Changed Sim - White Screen

So I have been using my imate PDA2k without a hitch, purchased it unlocked, and was using a local carrier somewhere in Europe (Voda). Went to T Mobile in the same country and put the sim in - BOOM - white screen on startup and it seems to have reset because I heard the pings to indiate screen alignment.
Took it home, used My Mobiler to looksee what is happening. Its all working fine, the screen and everything, its just white! And after several Power/Reset button resets everything is still there but on the device - white screen only. Power on battery and backup indicated 100% but backup battery for a while said "needs replacing" - then on settings now its 100%
The touchscreen works! I reinstalled the password and when I touch the white screen in the places of the four numbers, its ok!
But its all white! What can I do?

hi and welcome to the forum.
there are basicly two options to what could have happened, either something got messed up with the rom and after the sim changed it was triggered and went completely wrong or while changing the sim, you accidently caused a hardware defect.
another way to try that is: put the device into bootloader mode!
the way to do that is press power+record+reset. maybe hold the power+record a little longer after resetting.
if your device screen shows SERIAL V2.0x (where x is a number from 5 to 7), apparently your hardware is ok and just your rom broke. in that case, after you claimed you already hard resetted, you might want to flash that rom again. if i read your post correctly, you are still running wm2003se. if your carrier does not host your rom anymore, you can always refer to xplode's shipped rom archive here: http://firmware.atspace.com/Blueangel.html
if your device still shows only white, either when trying to access bootloader mode, or after re-flashing, yo might have harmed your hardware. you might want to check for a replacement screen. if you want to have a look inside your device, whether the display cable maybe broke, here is a link to the service manual: http://rapidshare.com/files/336406555/HTC_Blue_Angel_Service_Manual.pdf
i don't think it can have anything to do with the backup battery, but if that really was the reason, here you find a thread with someone, selling them: http://forum.xda-developers.com/showthread.php?t=551886
or you could upgrade your rom to wm5 or above, then the backup battery is not needed at all.

Thanks for the great response!
So I waited about an hour of using it with My Mobiler but with a white screen only on the device, and then waited a bit, and and just pressed power and reset again to see if yet another reset would work - and it did.
It was so strange that the previous times I tried to reset it didnt seem to work at all. But I knew that the screen was ok because I used My Mobiler and could press the password for the device on the white screen ok, guessing where the numbers were, and it activated fine.
So strange, but its all ok now. Thanks guys - this device is 5 years old!

mymobiler is a remote connection to the device, so that does not necessarily shows, that the screen is working, because it uses the usb port to determin, what the display would show, just like a remote desktop connection to a pc can work, even when your vga or dvi cable is broken, because picture information is sent through lan or wlan then, with a virtual graphics driver. also for some people, the touch feature worked fine before without the screen showing anything, because that is also another layer, that is transmitted through the digitizer. it could really have indicated that your display flex cable was broken, which is why i went both ways in my answer.
i am glad to hear it works again, just posted to clarify a few things
also, if you ever get tired of wm2003, make sure to have a look at d-two's wm6.5.3 rom in my signature and in this thread here: http://forum.xda-developers.com/showthread.php?t=569869
back in the day, when i still used wm2003, i felt quite excluded in mobile developments of the last few years, because many 3rd party applications would just work on wm5 or above and with that rom you can be up to date and use a lot of new features, which make the phone feel less like an old pda and more like a new phone. but now, that your device works again, of course that is completely optional.

Great Tony!
Although I am a little afraid to flash the rom to WM5 or 6 I should give it a go.
Im happy with the BA the way it is with some GUI software!
Thanks again!

i also had different gui improvements installed on wm2003, but still it didn't feel to fingerfriendly, which is important for me, because, let's face it, the BA is a modern phone, not some geeky 90s PDA , so fumbling around with a stylus is just not cool. also, whenever i looked on engadget i was incredibly envious of all the cool apps and GUIs. whenever i looked at ppc freeware pages i saw that most games, media players, browsers... would just work with wm5 or above, and after i found out, that it is incredibly easy to make your BA become a modern device (i would even go as far as calling wm6.5.3 a 2010 phone), i decided i want that, to kick every iphone's butt, to install any app i want, not to be forced to install 20 programs after a hard reset anymore, because everything already works fine and looks nice. i mean, these days, you hard reset, the extrom installs windows marketplace for you, you log in with your live account, it downloads everything you had installed/bought from there, including microsoft myphone and when you start myphone, you are already logged in, so it syncs all your pim data with the internet, and you have everything back. back in the day i was afraid i would lose everything i set up for ages if i ever had to hard reset, these days it just takes an internet connection and 20minutes of your time, to have your phone completely back up after flashing a new rom. it is amazing. before upgrading (the procedure for windows xp is to be found in the 2nd post of the link above) you should still make a backup of all your data, either through pimbackup (freeware by dotfred) at http://www.dotfred.net/ or with spb backup, available at spbsoftwarehouse as a trial version, in case you want to go back. about those backup apps, pimbackup is great because you can schedule backups of all your important information, also stuff that is not synced, like sms or the call history and restore it to any other rom or even other device, but it does not back up your installed programs (most of which you won't need anymore anyway.). spb backup on the other hand makes a backup of the entire system, and can restore the exact state of the device after a hard reset, including all installed programs and those programs settings, on the downside, those backups are worthless on another rom, just work for hard resets.
that was just a fair warning, because not everybody is happy with wm6.5's battery life and performance, especially when coming directly from wm2003. i started with wm6.0 and so i am used to those disadvantages, and since the roms get better with every new release, it is actually an improvement for me every time.
also i need to tell you, that by tomorrow, there will be a new rom released build 23518 by egzthunder1. yes, although the number is not higher, that rom is newer. but since none of us know, if that rom has any bugs, it might not be right to start with that one right away, you should probably try the one from my signature / from here: http://forum.xda-developers.com/showthread.php?t=569869 (same thing) because there, the bugs are known and listed. when you have found your way around the new OS, you can still switch roms in about an hour, as stated above, you travel light with the new roms, and as long as your pim data is backed up and you follow the instructions, everything will be fine.
with best regards,
Chef_Tony

I don't know if I can post this here, kindly let me know if this is the wrong thread to post.
I have xv6600 yes I am still using it
It seems that I have broken my Display cable as I don't get any display.
But sometimes when I Slide the keboard in and out many times I do get display.
I took it to the local mobile reparing shop and he says that the cable is broken but I will have to change the complete LCD, as it's not possible to change only the display ribbion.
I was a bit worried in changing the complete lcd as I am not sure what quality of LCD he is going to use.
I would like to know if it is possible to change only the display ribbion. and where can I get one. Your help will be greatly apprreciated I really love this handset and don't want to leave it
Thanks in advance

have a look in the service manual, there you will find the exact display used in the device. there is a photo of it on page 55.

Thanx a lot Tony for your quick reply, this forum is great I have learned a lot from this forum over time.
I saw the display from the service manual, infact the mobile repair guy had opened my phone and shown me the display, but I was concerned if there is any chance that i can just repair or change the ribbon instead of the complete diplay.

i haven't opened up my device, yet. i'm glad i never had to, but from all lcds i know, i think that the flex cable is integrated in the display unit and only has a plug on the other side, so you cannot detach it. also, you should think about costs. the cable alone probably wouldn't be any cheaper than the entire display and if you had it assembled in a local shop, changing the flex cable only (if possible) would be much more work than replacing the entire unit, so causing more costs. actually, i believe the cheapest way would be, buying an entire new BlueAngel. new devices go for 100eur here in germany. the official retail price for a display unit alone is 130eur.

[Q] [?] Total noob needs help

Hi,
I am what you might call a total Apple zombie, in fact I never had any other SmartPhone but an iPhone since '07. Due to the huge disappointment with the 4S, I was finally fed up and switched to the Galaxy Nexus. However, while this seems to be a cool developer phone, I have huge issues with using it in a productive environment. But that is probably just due to my own ignorance ...
[Backup&Restore]
Poor me is hit with an update notification like 50 times a day. I suspect that I will lose all data when I hit install so I am quite hesitant here. With my iPhone I did not even had to bother with stuff like that, it synced with iTunes over WIFi whenever I was in one my home networks. The Nexus does not seem to offer such functionality.
What I expect to be backup'ed is all:
of my mail (around 4GByte) that I frequently need to have available offline
my Navigation system and maps (Sygic + Navigon atm)
my music would be nice due to reasons I elaborate on later
SMS, phone records, etc ...
I tried the following means for backups already:
ADB: with command line "adb backup -apk -shared -all -f ./backup_all.ab" --> result was only 700MByte so I won't trust it a bit (my data is around 13GByte)
Titanium Backup: told me all worked fine but my phone has not enough free space for saving the backup to the pseudo-SD, the file is corrupted, and dropbox is rejecting the maps and my email account data (looks like they are bigger than 400MByte or something ...)
Google Sync: is missing all that des not have a google stamp on it
[EDIT] Noting is worse but to switch on Navigation and get the message that the map was not downloaded and to reload 400-800MByte of maps over a roaming 3G connection at the airport or use a super slow paid airport WiFi. Same goes for my e-Mail, I need it searchable and accessible.
What are the pro's suggesting here? I only have around 3GBytes of disk space available on my phone, the cloud services does not like big files, and the ADB backup seems to lack some stuff (though I cannot really tell what it is leaving out).
[Navigation]
I am abroad very often and do not like to pay insane roaming fees for online navigation systems. That is why I acquired two products, Navigon and Sygic since Navigon Europe is crashing right away.
I am used to the iPhone 4, which means: load App, set destination, boom, go ... My Nexus however, needs a warm-up of around 15 minutes and then constantly loses its signal. Furthermore the screen is not always auto-rotating so that I go in the wrong direction from time to time. Am I just too stupid to operate such things?
[Music Sync]
As I said, I am used to iTunes and all is synced automatically. With the nexus I tried Google music but it is not originally available in my country and it cannot find any management software apart from sync. The Music webpage does not let me logon since a couple of weeks now but the Music Manager works on Windows and uploads some of my files. However, how do I add or delete new songs? Am I stuck to add the to iTunes, import them by Music Manager, and wait for an upload?
I also tried Winamp sync but it crashes whenever I want to sync by WiFi and my Mac is not seeing the device sometimes.
[Car Mode]
Both of my cars support the iPhone by cable and BT. I usually use the cable mode because the phone needs to be charged anyway. My cars are playing the music right away and I can use the steering wheel controls to skip tracks, etc. With my Nexus all I see is "cannot play". When I use Aux-In, which sucks btw., I have no knowledge of any way to make the buttons bigger etc. I needs some filigrane fingers to operate that thing when on the go. The Google car App does not want to install itself because it seems to be incompatible with the nexus ...
How can a fit-finger syndrome person like me control their phone in a car?
[Network Access]
Whenever I am in highly shielded environments (that happens often), such as a underground parking garage, a hospital white room (MRT, CT, etc.) or in a research center with much electromagnetic interference, my Nexus is losing its GSM network access and this is okay. However, it does not gets it back when I am out again when I am not switch the phone off and on again! I have already had overflowing mailboxes so often that I have a habit now to restart my phone whenever I am outside again. That is ridiculous! Is that a hardware problem of the phone or do I just have a bad model?
I hope you could enlighten me, as I am totally ignorant concerning Android and their phones. They are indeed a world on their own! Please keep in mind that I am not very knowledgeable so I would appreciate human-understandable information

Included too much information. What update? I'm assuming you're stock and didn't root or do any tweaks?
Just update, all of your settings and such will still be there.

OTA 4.0.2, it is rooted for the Titanium Backup, stock ROM and kernel (4.0.1, KK1-Baseband, 3.0.1 Kernel), no other tweaks I am aware of.

An OTA update doesn't erase anything..

I'm in a similar kind of position and I think that provided you have standard recovery the update will work fine and you'll lose no settings although I've seen some suggestions you'll lose root by updating. Not sure how it would affect you if you have a non-standard kernel tho...

Having root doesn't mean anything. As long as you didn't do any changes to the kernel, or anything outside of /sdcard/ even though you have root. You'll be fine, it won't wipe anything. Just accept the OTA and everything will be okay.
I'd recommend using https://market.android.com/details?...m9yZy5wcm9qZWN0dm9vZG9vLm90YXJvb3RrZWVwZXIiXQ.. as it will keep your root access post-OTA.
@daz.g: Not having the stock kernel provided by Google and accepting the OTA is a huge-nono and will most likely fail. You can keep root with the app I linked above. But using stock ROM + stock kernel + root, your options are rather limited and it's better off going off with Custom ROMs. If people are going to be risky and root, might as well go all the way. Risking and flashing ROMs aren't even that scary

[Q] Experiencing major issues with any custom rom. Please help!

((if this is in the wrong place or has been covered before, I apologize...))
Hello all.
I just became the new owner of a family member's Samsung Galaxy S3 (AT&T). Already owning and tinkering with two xperia Ion's I wanted to have a little more freedom and experience Kitkat on the GS3.
I had no experience in unlocked bootloaders and all that, so I figured that I would let the Cyanogenmod Auto-Installer do the work for me and install CM11 on my device.
It worked great initially! No problems whatsoever aside from minor glitches here and there. As soon as I started installing some more apps and Xposed modules, I noticed that things were getting odd.
Eventually, my phone wouldn't connect to google's play services whatsoever. Despite countless resets of the phone itself and my modem/router, nothing seemed to help. Flushing the cache and dalvik didn't help either, nor did a factory reset. The issue kept coming back.
Thinking that perhaps another rom wouldn't have the problem, I installed C-Rom (which was based on 4.4.4 KK). It ran BEAUTIFULLY! It is sure one hell of a rom. But then, not too long after I had everything installed and running the way I wanted it to, it had the same errors as before.
I don't know how to explain the error other than the phone just generally messing up. I don't recall it ever having those issues on stock, but then again, it wasn't my phone on stock, and the first thing I did upon receiving it was put a custom rom on it.
But the error can only be explained as a general f***-up of the entire OS. Commands run brutally slow (I will launch the flashlight and it wont turn on until seconds, even minutes later. Alternatively, text messages take eons to send and receive, which I am positive is not an error on the AT&T side of things). Then, whenever I try to download or install an app from the play store, the application will download partially and then stall for what feels like eons. Some of the applications just stop there, and some I will find installed on the device some 30 minutes later. Not to mention that the signal icons on the quick setting tiles are all turned orange for some bizarre reason. Another bizarre issue is that no matter what, I can never launch the terminal to execute an htop, logcat, or anything! The terminal just stalls and eventually crashes, while it worked fine before.
I've checked online for errors similar to this, but haven't found anything that has helped the phone. Anyone out there who is willing to give this a crack or just point me in the right direction?
Thanks in advance.

It sounds like you're the modules you're installing are crashing your system. I'd suggest you do a clean flash of w/e rom you wanna rush (you seem to like C-rom) and run it clean for a few days. You can install apps and such but don't restore system apps and don't install modules.
If it runs fine after a few days, you can cherry-pick the modules you wanna use (make sure they're made for the sammy phones). Install one or two, test for a couple days and so on. You'll eventually find which one is messing with your system (if that's actually what's causing the problems).

All seems to be well now. I've isolated the problematic app after slowly restoring all my app data one at a time. I have since moved to a different rom (SOKP) and everything is going running smoothly! Surprisingly, it wasn't Xposed causing the issue, but a market app that displays system info similar to conky on Linux computers. Once I installed it, the system just crapped out. Signals dropped, the terminal froze, and none of my apps seemed to work properly. But once I uninstalled the app and reset my phone, all was well.
Thanks for pointing me in the right direction!

Note 4 Verizon no 4g and now lost 3g - in a strong 4g / 3g area

SOLVED! - see post #7
This SM-N910V is rooted and had 3g but apparently I lost that when mucking around with things trying to get 4g. I've got other phones like a Galaxy S5 and Galaxy Note 5 both Verizon models that get 4g or 3g fine in this same location.
First odd thing I noticed on the Note 4 was a setting that popped up seemingly by itself while in 'More Networks' and 'Mobile Networks' that showed VZWInternet with a circle by that which was not yet checked so I tapped that and it turned green in the circle. I have never been able to see that option again. I don't think this caused the problem though. I've looked at apns-conf.xml in the /system/etc folder and can't see a problem there. I also tried replacing that with another one that is supposed to fix LTE mode. No luck so I put back the original. I wiped cache and reflashed a backup with TWRP which had been working on 3G but that didn't help - no 3g even. I did not wipe Dalvik/ART cache. I had been messing around in the 'Service Mode' menu with a bunch of different settings in an attempt to get 4g working but I'm fairly certain I got everything set back the way it was before I started. I noticed that one setting I had left different in the Service menu did not change back after flashing a restore with TWRP (full restore - all boxes checked). The one setting I left changed was the under the 'AS' protocol menu where I changed the Release version control to "LTE 3GPP REL 9" from LTE 3GPP REL 10". I know enough to be dangerous
Open to any suggestions - am wondering at the moment if I should have wiped the Dalvik/ART cache before the whole TWRP restore? At this point I'd be happy just to get 3g working again.

I also tried Dr. Ketan's LTE Enable. That didn't fix anything. Although I see MNC and MCC numbers in the apns-conf.xml file when I look at the SIM with a SIM info App I just see blanks in those spots on the SIM. Not sure if that's relevant - just giving as much info as I can here.

Did another restore with TWRP after wiping Dalvik/ART cache but that didn't fix it either. Strong cell signal but no 3G or 4G.

More info - I put the SIM card in another phone and it sees 3G at least.

It seems the "lost 3g or 4g" problem is very common and it seems I've looked through dozens of message threads here but I'm not finding any solutions. I'm looking at flashing the 'ltefix.zip' from this thread but it seemed to be for a custom ROM and I've just got the stock - more or less - 5.1.1.

Hmmm.... Been at this all day reading here, searching, trying everything but still no Mobile Data. Is this as elusive as rooting a Verizon Note 5? LOL - it was working at least on 3G. I'll take hints or even wild guesses at this point.

Okay - it finally flashed on me to do a restore of my EFS. Oddly I had done a full restore with TWRP which include EFS but that didn't fix the problem. That TWRP backup was done the same day I did an EFS backup using Dr. Ketan's IMEI tool for the Note 4. When I used the IMEI tool to restore the EFS backup I then had the 3G come back on. This is a 4G SIM so I still don't know why I'm not getting 4G but at least I got 3G back. I did have a hiccup using this IMEI tool which initially caused the phone to repeatedly shutdown after a minute or so and could not be restarted without pulling the battery. I believe it had to do with the 'Restore' button needing to be held down a certain amount of time instead of just a tap. I probably held, released too soon then held longer which I suspect caused a partial or damaged EFS restore. Be careful in how you use this tool or you may end up in that situation. I had to work very fast after a bootup to get it properly restored. After that it was stable again and had 3G.
Now if only I could figure out what it takes to get 4G.

..

I wasn't getting 4G for the longest time, checked the PRL in settings on my GFs phone and noticed my PRL ver was like 50 thousand something while hers was 15518. Got a new Sim card and all my issues went away, PSA do not use *228 programming...EVER.

Update/more info - I've continued to try and figure this out to no avail, although I got fed up with stock unrooted 5.1 and am now running modestrom v9 with a CQI2 base. And all of that install went fine, except for 4g of course.
I think this is worth mentioning as it might have something to do with the situation:
Way back in the beginning, I had gone through the entire unlock/root process, and everything actually worked fine the first time. This was right about the time the unlock became available, I bought the phone based specifically on that being possible, and got a brand new one at that time. Well, it was awesome for about 2 weeks, fully functional 4g and everything.
I had a very particular goal - I wanted this phone totally unlocked, but I was also very interested in the advanced/wifi calling that was supposedly coming out at that time - I was planning to move to a place with no vzw service and would be reliant on wifi for calls at home. Verizon wasn't clear about the fact that the wifi calling feature wasn't coming until MM, and this was before MM was released, so I was running a completely functional, 5.1.1 rom. I believe it was jasmine. So, under the impression that "advanced calling" would have given me wifi calling, I tried to enable it.
I cant recall if it was immediately, or a few hours after, but this is when the phone lost 4g for the first time. I immediately tried to deactivate the advanced calling feature on my line, but it didn't help. And nothing I could do would bring back 4g. I tried everything possible, and ultimately gave up and threw the phone in a drawer and went back to my note 3.
Fast forward several months, and my note 3 began to have issues with call audio, forcing me to use the 3g-only note 4 in order to actually handle day to day business. Again, I went through the processes of trying to fix 4g, with no success. Now by this time, MM had been released, I believe PD1 was the current firmware. I figured at this point it was time to just odin back to 5.1.1 and start everything over.
So I odin flashed the phone, and it booted into 5.1.1......with no 4g. Again I went through all the things I found here, no improvement. Finally, one day when the phone was bugging me about an OTA, I figured "what can it hurt at this point, its nearly useless without 4g anyhow."
And low and behold, the OTA update from verizon booted up and immediately jumped to 4g.
Now I felt I had a chance, a method that I'd finally proven could fix the problem. I left the phone in that state for a couple weeks, just to prove that it was holding. No problems during this time.
But I got sick of no root, and so I figured it was time to try and go through the steps again. And again, I lost the 4g connection. No big deal, just odin back to 5.1.1 and let it OTA like last time......
Except this time it didn't work. So I odin flashed back to 5.1 again, and let it try to OTA, again. I let the phone continually try to OTA all the way up to current, and flashed back to 5.1 at least 3 times to repeat the process in hopes it might fix something. No change at all. At this point I actually began to try and see if possibly Kies could help me here - maybe there was something related to the phones EFS? Which I don't understand very well btw - it was only through reading this thread that I began to research EFS and its significance. I also attempted to use some of the checkboxes in odin - the ones to erase all NAND and to clear EFS and rebuild it. Neither option made any difference. So I figured next logical step was to start playing around in service mode, which would require unlocking/rooting again......
And thats how I landed here. About an hour ago I got sick of the stock 5.1.1 and went through the whole root/unlock process and I'm currently running modestrom on CQI2 or whatever was just most recently posted. Every other part of the phone seems normal, but still no 4g. I can actually see the radio making an attempt to connect in the service mode - but I don't understand service mode menus well enough to interpret where the actual problem is. Upon boot the phone tries about 3 or 4 times to get an lte signal, during this time there is simply bars of signal, NO data indicator of any kind. Eventually, it gets frustrated and gives up, connecting to 3g and staying there. I realize now that when 3g drops, which is roughly every 10 minutes or so, its actually the phone attempting to establish LTE again. But still, I cannot make any sense of this.
Apologies for the giant post - I'm trying to put anything that could possibly be relevant info into one place here.
So........ anyone got any suggestions?

PM sent. Just to share a little of that here I think the first thing I would do is tell VZ you suspect your SIM card is bad and have them put in another one. Tell them it fell out when changing a battery, the dog ate it and by the time it came out you suspect it wasn't quite right anymore - LOL. I do think SIM's flake out sometimes and I know a bad one can prevent 4G from working. If you ever had an EFS backup from anything try restoring ONLY the EFS (if you use TWRP). No guarantees that will fix it but my best guesses at this point. Good luck.

I supect Verizon's doing this ...

I got a used stock note 4 to try and compare and see what I could be missing here....
Tried new sim card at least twice, unfortunately no dice, and the same card pops right into the spare note 4 and it wakes up on 4g just fine.......
EFS is something I probably should have been quick enough to dig in deeper on before this, as I don't have any backup of it....... however, I'm not seeing any other symptoms, I can see my imei fine, and every other function works. Is it possible that corrupted EFS can cause the loss of just one type of connection like that?
For giggles I tried a friends att sim, and no lte on that either.
Playing with the app LTE discovery, I can tell that the phone sees 4 different LTE towers just fine, showing db numbers exactly in line with the stock note 4 sitting right next to it, theres just something there under the surface thats stopping them from hooking up...... it stops trying after a couple minutes, rejects them all and connects to 3g.
I'm convinced its some kind of software thing, but I can't tell exactly where the failure is happening.....
I also odin flashed it back to stock bpa1, and still no dice. Is there a means to make an EFS backup without root? I want to see what happens if I try unlocking the other note 4 as well, but this time I want to have the backups......

I've been running on Emotion 7.1.1 for months with NO issues (well, some minor stuff, you know....)
Suddenly, two weeks ago I got a notice from Google that I had to sign in on my phone. Verrrryyy odd. At first I suspected some hack attempt, but my Account checked out fine. Having changed my password recently, I had to wait until I got home to login.
After I logged in, all ~appeared~ to be OK. Then I opened my Calendar. B L A N K. All ten years of appointments gone. I freaked out. I have two calendars, one for personal stuff, birthdays and the like, and another with my business appointments, INCLUDING FINANCIAL STATUS of the account. Gone.
Went online on my PC, signed into Gmail and switched to my calendar. Empty. Looked in Trash. Nothing. Vanished. Nada. Niet. There's a long story here about recovery efforts, troubleshooting, Googling, etc, suffice to say that TWO separate, redundant, backups had quietly failed, without the notifications they were supposed to send. I did manage to get from the first week in April back 10 years, but lost the whole summer. Thank YOU-KNOW-WHO that I'm good friends with all my clients.
Fast forward to last week. Suddenly I get 3G only from my Verizon account. Like you, I spent days on the boards, downloading ROMS, wiping, re-wiping, trying everything short of smoke signals to get it back. No joy. I did NOT go back to stock, I must thank you greatly, as that was my next road. Now i see it's a dead end. I will NOT give up my Nougat root just to get 4G.
Perhaps this is a bit conspiracy theory sounding, but I've become convinced that Verizon is playing some game, perhaps to force us to upgrade to a new phone. I learned long ago that corporations have no soul, and will do anything they like to increase profits. They exist for two reasons; to make money for their officers and to make money for their stockholders. Any other semblance of a "Product" or "Service" exist ONLY and SOLELY for that reason. Anyone who is a Yahoo or AOL member knows the level of intrusive ads and attempts to trick people into putting spyware in their machines under the guise of "protection" or "cleanup" programs has jumped to a new level of absurdity since Verizon sucked them up. "Oath" indeed. It's what is coming out of existing customer's mouths! M O N E Y H U N G R Y.
When I chatted at length with a Verizon Tech, she made it clear that she knew the answer was to upgrade to the latest stock (I never admitted to rooting, but she knew, we spoke "between the lines" a lot). She sent me a SIM card, but it., of course, didn't fix the problem, in fact it would not even initialize properly! I had to go back to the original SIM.
Now that we've found a way (after YEARS of trying) around their stupid block on rooting, they change the game. What person who is so into their phone as to root it, will put up with 3G? This is something Verizon is playing at, Sprint too from what I gather.
My only consolation is that I've got so many WiFi's nearly everywhere I go, and when I'm not near one, my Wife's Note 4 (not rooted, on latest update) works fine. I'm glad I decided not to root hers too.
Frankly, this really ticks me off. I have better things to do than spend days copying files, flashing and reloading data. Verizon knows that, and let me tell you, it won't be THEM who sees my money when I finally do upgrade.
Thanks again for saving me from the Stock route, you saved me hours of grief.
Peace out!

I have run into 4g issues with this as well and almost came to conclusion is a modem issue. I want to say but can not confirm that modems that are flashed are relative to bootloader on the device. Just something I've been pondering on as I had a unlocked bootloader device and flashed for wife to use with no root and recently unlocked again.

SIM card recognized but no service

TL;DR
Moto Z2 Play - XT1710-07
The phone recognizes the SIM card but there is no signal (no service). Tried several things, including flashing a custom ROM. I'm considering buying a new motherboard and changing it myself, but first want to know if anyone knows more about this issue or has an idea/suggestion.
Edit: As an added bonus, something that only now I realized. Now when I charge it, it gets EXTREMELY hot. Like I-can't-even-use-it hot. I used to use the phone while charging all the time, but now I can't even hold it. Seems like the problem is when it tries go past 80% charge. It gets super slow, keeps trying and gets hot. Now I don't know if it's a software problem caused by the various flashings or if it's something that would remain even after swapping the motherboard.
Edit 2: I did a full discharge of the phone and recharged it while turned off. It seems to have normalized the battery problem
Edit 3: RIP. I tried to remove the screen before deciding about buying a new board. In the process, I ended up tearing the digitizer flat cable apart. Now I don't think it's worth it buying both a new screen and a motherboard.
The full story and things I've tried
My phone was working all nice and dandy until it stopped having signal/service. Wifi works normally, but anything related to the SIM card doesn't, like phone calls or mobile data.
A list of things I've tried somewhat in order (both of time and of complexity):
* My SIM in another phone: it works normally, so the problem is not the SIM itself
* Another SIM in my phone: it doesn't work, so the problem is definitely the phone
* Using the second SIM slot
* Changing "Preferred Network Type" between the available ones (4G, 3G, 2G, including Enhanced 4G LTE Mode on and off): this one and the next two items don't really make sense to me, since these options seem to be only related to mobile data (4G/3G internet) connection, not to phone calls which is also not working, but I tried them anyway
* Manually selecting the network: Errors with "Selected network unavailable" and, after trying to register for a while, toasts another error saying "Can't connect to the network, try again later"
* Manually selecting the APN: Tried both selecting between the two options available and manually adding an APN by googling the correct info for my carrier
* Simply booting into fastboot and restarting bootloader: a video on YouTube claimed that it was a temporary solution and that I'd need to do it every time it lost signal. But it didn't even work the first time
* Disabling CQATest and then restarting bootloader (and also clearing its data/cache and removing its permissions): a lot of videos on YouTube claimed this was a solution, including for other Motorola phones. Apparently CQATest prevents the phone from working properly in some scenarios. But I think only when you de-google your phone? Not sure. All I know is that it didn't work either
* Using the phone connected to the wall charger: I think this was another YouTube suggestion, and it actually worked for a few minutes. But I guess it was just a coincidence, as it never worked again
Now for some more... "forceful" attempts:
* Factory Reset: Not sure where I saw this suggestion, but it was pretty much the next logical step. Gathered courage, backed up all my data, etc, aaand... nothing again
* Flashing another ROM: Guess it was here at XDA that I read that it was a problem with Motorola's stock ROM. That, paired with my belief that it could still be related to CQATest being installed, I again gathered more courage to flash a custom ROM. I chose LineageOS and found out that it was no longer supported, but decided to install the last official release. I also read that the problem was the Pie modem firmware, so it all seemed to be going fine since the last official release is Oreo 8.1. I flashed it and BAM it worked! ... for a few minutes and never again. I messed around with LineageOS, tried some of the previous things again, but nothing.
Then, I tried to restore my TWRP backup but it didn't work. So I searched a bit more and downloaded the Stock Pie ROM, flashed it, and closed the bootloader. And then I realized the restore probably didn't work since my backup was made using Pie and my phone was on Oreo. Maybe some files/partitions were missing? Also, when I was creating my TWRP backups, I tried creating a full system image backup but it kept erroring. Only later I realized the problem was that the USB Drive was FAT32 and the full system image was bigger than 4GB. Oh, well, now I know.
So now that I'm with my phone pretty much back on square one, I take it to an authorized repair shop. The clerk said that it was a common problem, and that sometimes it could be solved "by software" and that they'd try that. The other option was to change the whole motherboard, which they didn't do because it was "not worth it" and "almost the full price of a new phone". After two days, my suspicions were confirmed: they didn't fix it with their "by software" attempt. At least I didn't have to pay anything.
When I got the phone back, I put the SIM in again and it showed the icon as if there was signal. But when I tried to call someone, the signal disappeared again. I tried searching a bit more, went through all pages of Q&A here at XDA forums and there were like 3 posts regarding loss of signal. All without any response. On YouTube, I found some videos offering a suspicious .bat file. Upon inspection, it merely erased the modemst1 and modemst2 partitions and then wiped user data and cache. I tried it, nothing to lose. Also didn't work.
Now I'm contemplating a few options:
By watching some disassembly videos, I saw that, when opened, the phone has some parts that act like antennas. I thought that maybe those were not properly connected to the board? Maybe they got dislodged during a fall? Seems unlikely tho, since they are screwed in. I searched for a new motherboard to buy and it's a reasonable price. But I'm afraid it'll have the same problem (or develop it in a short time) since I can't find anywhere what the true cause of the problem is.
Another option is to just give up, buy a new phone and use this one as if it was a "small tablet" lol
So, do you guys have any other suggestions or ideas as to what might be the problem? Maybe a tip like "solder a wire to this spot to create a make-do antenna"? I don't really know where else to search.
If not, thanks anyway for those who read it all
