SOLVED [HELP] LG G4 (H815P) Bricked "Authentication Fail #9" - G4 Q&A, Help & Troubleshooting

Hello everyone
So, this is my problem here, I got my G4 last week, rooted it to debloat, followed the instructions I found here on XDA, and it was working as a charm.
The problem came when I wanted to change the (micro) SD card to another phone, I took the back cover off, took out the SD card, and a warning message about the SD card might be damaged came on screen.
So I turned off the G4, after I was ready to put back the SD, tried to power on the phone again and the error message appeared.
"Security Error, Auth Fail #9" and then it just won't boot.
Hope anyone can help me.
I was on stock Telcel Firmware, had rebooted the phone several times before with no issues so far.

Never mind, I just reflashed stock firmware found
here: http://devtester.ro/projects/lg-firmwares/
then followed this steps
Tutorial: http://devtester.ro/projects/lg-firmwares/install.php
So, after a clean flash, it booted again, as Iv'e had it for just one week, nothing was lost.
Hope this helps anyone else facing this strange problem.
By the way, if anyone know something about the possible cause for this malfunction, I woud really appreciate you sharing info.
Cheers!

i Have had the same problem i was woundering if you could please walk me through the steps on how you fixed yours.
I recently just bought a new LG G Stylo with MetroPCS. this is my first time being with android so i took it upon my self to root the phone and see what all i could do with it. Everything worked fine for a couple of days then i tried to reset my phone and when it tried to come back on the lg logo cane up and it said Authentication fail #9. I try to factory reset the phone but it goes back to the same screen. I can not put the phone in download mode and my computer does not detect that there is a phone there. If there is anyone who can help me please it will be greatly appreciated.

How can be LG G4 H815P be rooted, have read many tutorials, but no one is for the variant "P" (Telcel).
Thanks!!!

Hello!
Well, I found out the source of the problem on "error 9".
As it happened again a couple days after posting the thread.
In my case, when I uninstalled LG apps, such as music and video apks, "error 9" would come up on next boot.
Follow the tutorials, the most important thing is to have the right version of SW to your phone.
Also, I had to download LG bridge, then a pop-up came telling that drivers for the phone should be updated, I just accepted the update and then my phone was detected on my PC .
If you encounter a problem, please provide me a little more info (with caps if possible).
Hope to help you.

@joyousfrank. I've just been de-bloating my phone and managed to get a Security Error problem and was hoping to use this method to get the thing live again. Trouble is that Google is blocking the LGFlashtool download link. Any chance you have another link or could maybe upload a copy of the tool somewhere? Cheers

I used this thread as a guide
http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
(Follow the steps for International H815 10c Version)
This is the rooted image I used http://forum.xda-developers.com/g4/...on-root-lg-t3164765/post62251256#post62251256
After you download it just unzip it, and rename the .img file to "system.rooted.H81510c-EU"
The file must be system.rooted.H81510c-EU.img
Hope to help.
Cheers!

Hello!
The first thing to do, is to find the right SW foy your phone model (and carrier) as I read some problems when flashing other different than stock.
Look up here http://devtester.ro/projects/lg-firmwares/download.php there's where I found the SW for Telcel. Just input your IMEI on that page and it will give you a download link.
Then, follow this steps http://devtester.ro/projects/lg-firmwares/install.php
It's important to tell you that my phone wasn't detected by my PC until I downloaded LG Bridge as it comes with the latest drivers, so I recommend you to do this if you face the "not-detecting phone PC".
And for last, I suppose that there should be thread with a list of safe to uninstall apps (this is my first LG so not totally sure).
As there's enough room for apps on the phone, I just ended freezing annoying apps with Link2SD to avoid having the "Authentcation Error #9" problem.
Hope to help you, cheers!

[Q] Sprint LG G2 LS980 - no data, no signal, PLEASE help

Here is my OG post...please, anyone, help me to know what YOU would do in this case. I'm freaking out that I have a $500 paperweight I can't take back to Sprint because I'm rooted and on a custom ROM. AHHHHHHHHHHHHHHHH

Please help me, anyone. I am freaking. I flashed this ROM per the instructions (no I did not do a backup, my fault). However, although the ROM loaded, it told me I needed a T-Mobile SIM for WiFi calling to work. That may have been discussed before. That is irrelevant.
Since flashing this rom (Yes, I did the ROM, Modem, Reboot, and Firmware as said)...I can only make "Emergency Calls," I can't connect to data, can't connect to Sprint cell signal, and for the first time I can't get LG Flash Tool to work to get me back to Stock.
Can someone, anyone please tell me what to do? I need my phone soon because I'm leaving, but nothing works!!!!
Billy

Hi if you have LS980 you need to download room for LS980 here is the link: http://forum.xda-developers.com/show....php?t=2754167
Than you need to boot into recovery twrp and than you need USB OTG Cable here is the link on ebay: http://www.ebay.com/itm/13cm-Micro-U...item35d4da865d
Copy LS980 room zip file to to flash drive connect to your phone thru recovery mount usb otg than flash ls980 zip
You will be back on Sprint and after that LG Flash tool will work to if you needed

Thanks again for your instructions and help. I got the OTG, followed your steps precisely, and it SAID it installed Stock ZVC successfully (twice, actually)...yet it still will only boot back into TWRP. In download mode, LG Flash tool still doesn't work. This computer has all drivers, Windows 7, and had no issues before this ROM.
Do you have any other ideas? Now I've bought a cable for no reason. Help, please!
__________________________________________________
EDIT: I used these instructions to get me out of the TWRP Bootloop:
http://forum.xda-developers.com/show....php?t=2451696
Now I have the Stock Rooted ZVC Odex ROM installed, but STILL, no data, no signal connectivity. I try to update PRL and it says authentication error. I try to make a phone call and it says "Emergency Calls Only." This stuff ONLY happened after this (TMobile ROM). Please help me if you can. I've made major progress with your OTG instructions and getting out of the OTA TWRP Bootloop. Now how do I get past the "authentication" error and get the data and signal restored? Can Sprint do that from their side?
Edit # 2: I called Sprint, they walked me through fixing the MDN and MSID, factory reset, nothing works. It still shows "NO SERVICE," "AUTHENTICATION ERROR," AND ALTHOUGH IN MDN AND MSD my # is correct, in SETTINGS it shows my old (pre-port) phone number.
He told me to take it to a Sprint Store but clearly I can't because I'm rooted and on a debloated ROM. Please, any advice is so much appreciated.
Thank you,
BIlly

This SOUNDS like the answer...but I'm missing an EFS backup and these 2 files. Can I get my hands on these two files?
modemst1.img and modemst2.img????
Thank you... http://www.shiftpda.com/archive/index.php/t-12042.html
I've had this problem. I do think this phone can be wonky when using custom ROMs. Some people have no problem, others have constant problems, and some have problems SOMETIMES. There is no right answer so far.
I would just continue flashing different ROMs until something works. This worked for me: http://forum.xda-developers.com/showthread.php?t=2775888
But unfortunately now I have the dreaded touch dead-spot.

Yes, they did (hence the reference to LG Flash Tools). It sounds likeyour EFS partition got wiped. If you didn't back up your EFS, I think you're kinda SOL. From what I've read it's nearly impossible to get back your EFS data if you don't have the files. If you can find a way to hack it out by using someone else's files, let me know. I have mine from every backup I've done and if I can remove my info from them I'll post them. Sorry to hear about your issue, hope you find a solution.

I think I have great news. I looked in my ioroot folder and found both of the files (3 MB each) that are modemst1.img and modemst2.img.
I created a folder on the Internal called EFS_Backup, and I copied and pasted those two files into the new folder, renaming them efs1 and efs2. They renamed and stuck in the folder just fine, but running the ADB commands didn't work. So I used the flashable EFS zip in TWRP and it said FAILED.
I'm thinking since I have these 2 files I should be able to fix this, right???? But...the thing that's driving me nuts is that LG Flash Tool, no matter what version, will NOT work on my device anymore. Not with either of my PC's.
Does anyone have a suggestion for what to do now that I found those modem files in my ioroot folder?
I feel like this is the closest I have gotten and now I'm stuck. LG Flash Tools never worked on Windows 8. The OLDER versions worked fine with .tot files BEFORE all of this happened, in Windows 7. Now even Windows 7 won't work to use LG Flash Tools, after I created this mess.
Can anyone PLEASE help me take these 2 files and get them to fix my EFS? I really don't know what I'm doing, clearly, or I would have backed up my EFS first. Problem here is probably same everywhere...I've always done this, never bothered with Nandroid or EFS backups, but also never had the issue of only having an internal memory on an Android device. Stupid mistake.
I would greatly appreciate any help that can be offered. I have one more day and I can still take this phone back...IF I can fix it. Thank you in advance!
PS: I Have my ESN, MEID HEX, MEID DEC, IMEI, ICCID AND IMSI - ALL POPULATED WITH NUMBERS IN SETTINGS. WHAT IS "UNKNOWN" IS MY PHONE NUMBER AND MY PRL.

[Q] [x-post from LG G3] D851 unroot / restore to stock

I recently picked up a D851 (TMobile). I rooted it, but did not replace the ROM or install a custom bootloader.
Last weekend, the phone started randomly rebooting. Watching logcat via adb showed me several random apps throwing sig11s, after which the phone would give up and reboot. Cycle repeats.
This looks like a hardware issue, as the apps that crash change on each boot cycle.
I arranged with TMobile to swap the device, but they cautioned me that the phone must be returned to an unrooted state.
I've had a hell of a time with it from here. My first try was to install the LG drivers and the PC Suite under a Windows VM, as I do not run Windows at home. Enabling USB passthrough for the phone to the VM let Windows see the phone, but the LG drivers would invariably fail with 'Device cannot start. Code 10.'. Likewise, the PC Suite couldn't find the phone.
Next step was to throw together some spare hw and install Windows 7 on that (a desparate move, to be certain. ). The LG drivers can now recognize the phone, so that's a definite plus. The LG PC Suite, though, claimed that my phone could not be upgraded. Wonderful.
Next step was to try this tutorial: http://www.androidrootz.com/2014/07/how-to-unroot-lg-g3-all-variants.html . I was able to get further with this method, but as it begins to flash SYSTEM, it pauses, and then dies with 'We can't communicate with Phone'. End result - I now have a soft bricked phone. On the phone, I see the port - COM41 - appear, and the usb animation starts to spin ... and after a few seconds, stops. It's at this point that Flashtool throws the Can't Connect error.
I next tried following this tutorial: http://forum.xda-developers.com/showthread.php?t=2785089 to flash a KDZ. The newer LG Flash tool used here can't create a connection to my phone for flashing.
I've run into a wall here. Any ideas on where to go next? I need to reset this phone back to a working stock state so that I can send it back.

Also - as silly as it sounds, make certain you're using the USB cable that came with the phone. This has solved problems for a lot of people when trying to revert to stock.

I wasn't initially, but I did switch to it last night. Still no go.
I suspect it's either the phone itself (see above: re suspected hw failure), or the PC in question (nVidia chipset on this old motherboard, and I've had more than a few problems with adb talking to phones on nVidia motherboards). I'm going to try Bacardilimon's suggestion tonight, on a PC that has *nothing* nVidia-related in it, before I throw in the towel. As it is, the failing phone needs to be back to TMO by the middle of next week, so I'm all but out of time to resolve this.

There is a link in the general thread on how to return to stock including a method using twrp. It's a sticky thread at the top I've never done the twrp method myself but it can more than likely be done without a computer. Twrp can be installed via Playstore if you don't already have it

Holy hell. That site's links are absolutely infuriating. Anyone who puts each and every download link for software referenced by a howto behind separate timed appearance links that you have to ALSO enter an annoying captcha to enable should be shot out of a cannon - or, at the very least, have their howto ignored by the rest of the world.
Suffice it to say, the quality of that page doesn't give me much confidence that this will work any better than what I've tried already. Since I've already wasted a crapload of time on this project, and more on following those damned links, I'll give it a try tonight, but I'm not going to hold my breath.
Is the author of that page an XDA member? If so, please let me know who he is, so I can berate him personally. Thanks.

I'd consider doing that, except as I mentioned, the G3 in question disconnected during a run of Flashtool, rendering it without a working OS to boot to. The phone now boots straight to download mode. The good news is, it's now officially unrooted. The bad news is, it's also officially bricked until I can get an OS flash to work.

After going through the painful process of clicking his links, I found that everything I downloaded is the same thing I already had, except for Flashtool - lgg3root's is actually older. Even the TMO firmware for my phone and the dll are both exactly the same, and I checked by running md5sum on them.
But hey, it must be me. There's clearly no other technology-related cause for this issue. I obviously don't know how to follow a howto, right?
Thanks for 'keeping it real'.

Not likely.
In any case, it failed again. The video he did gave me the exact same steps I followed elsewhere, and unsurprisingly, it failed with 'We can't communicate with Phone', after beginning the flash process. There is something else wrong here, though I'm not certain if the failing phone is at fault or the PC in question is causing the issue. To be crystal clear, the flash process starts, and then, at a random point during the flash, it completely stops, and Flashtool eventually gives up and throws the aforementioned error.
Any other ideas? If not, I'm going to have to try another PC to rule that out as the culprit. Sigh.
Mine gave the same error as well as couldn't communicate with server but the flash process continued running and the phone rebooted took about 3 minutes u learned not to touch any of the popups on the screen during flash and sorry I missed the part about no OS I thought you were booting to recovery... Driving while reading not the best idea

Nope, the phone is definitely not doing anything - the usb animation on the G3 completely stops before Flashtool throws the error.
And damnit, quit reading while driving. You can do that later.
Moved the hdd Windows is installed on to another PC with a different chipset. After it updated drivers, I tried again. Flash proceeded partway, then died. Reset phone, Flashtool reststarted flash from scratch, flash died at 15%.
15% is interesting. While I've seen the flash die at various points, 15% is the one that was most often repeated. This tells me the failure follows the phone, not the PC - which makes sense, as the phone has a suspected RAM failure.
At this point, it appears that flashing this phone is impossible due to faulty hw. Hopefully TMO (and eventually, LG) will accept the faulty phone back with no OS, because there's no way an OS is being written to this device ever again.

[Q] Hard Bricked D851

I bricked my T Mobile G3 D851 by flashing Dark Knight 5.0 rom that was in this thread. I didn't think much of it because normally roms are in the right places in xda, I understand its my fault and there is no one to blame but myself. I just need some help restoring it. It does not turn on at all. I plugged it into the computer however, it showed some life. My computer was installing the drivers automatically but it fails. So there has to be a way to fix this right??

If you can get into Download mode, then your softbricked and can reflash full firmware.. If not, Then sorry, unless you have a Jtag, there is not much you can do.
The drivers you think are installing are not the ones that you could use to do anything. I only know this because I have hardbricked a G3 before as well.
Hopefully yours is only softbricked.

When plugged in and your computer recognizes it, starts installing drivers it could be drivers adb, I would think if the phone was truly off it wouldn't do anything. Could be wrong tho, do you have adb set up? What happens when you run adb devices?

Its not the adb drivers your thinking of, Its something else. I forgot what its called but it only comes up when you brick your LG, its something as in the area as nullUSB or something liike that.. I been though all this before. But I hope its not that.. I hope he can access his phone some how..

What drivers are installing is what im asking. what are they listed as .

So when the phone won't power on at all the computer will still detect it to install drivers? Not trying to be a smart ass, I have never bricked anything and truly just curious.

Its not really drivers for the phone.. anytime you plug anything into a USB slot something shows up.. doesnt mean its what you want.. I had something NULL show up when I bricked mine. I by mistake formated EAF partitioned and messed up to the point of NOTHING........... I got my money back and bought another someplace else

don't waste your time trying to get it fix.i did the same thing and i never found a way to fix it.i bought the phone second hand so no t-mobile warranty then my only solution was calling lg and since the phone has a one year warranty with lg it do not matter if you have a receipt or not. i send it to lg with label and ra# they provided.took 2 weeks but lg fix my lg g3 for free. try that.for what i found out is the only solution at the moment for hardbrick.
If it doesn't turn on, I suggest you either use your warranty for LG Repair Service ( like I did) or get a new replacement from LG or T-Mobile. There is no way to fix this problem atm and if your computer recognize the device, its going to be called QHSUSB_DLOAD. It took me a week to figure out that I had to send it to LG. Remember guys, this is hardbricked( can't turn on/ dead motherboard) so no download mode
I really don't want to send my G3 to Lg because I'm a senior in High School and I don't want to lose my pictures :/ I have an animation on popping up now but its for low battery i guess. other than that nothing is happening. I'll post a pic

sorry to tell you this but everything on that phone is already lost.send it to lg for repair it will only take 2 weeks and you will have a working phone again.when i bricked mine i spend 2 weeks trying to fix it i even offer a bounty to anyone who can figure how to fix it and no one could finally give up and called lg.

If you dont wanna loose your pics, that should have been backed up on external or cloud then your prob out of luck. but you can also find some phone repair place and let them hook your phone up to Jtag and reflash your phone... jtag is hard to explain, it requires soldering...... So if you dont know what it is, then dont try it your self.
PS:.. Tell us what it says in Device manger when you plug in your phone to USB.. click view and view hidden devices in device manger. take screen shot if you must.
you might just might be able to fix yor problem. if you can see the bat thing. then could just be a softbrick.. but without download mode you wont be able to fash anything.

Your pictures may still be available to you. I had to turn off auto syncing for Picasa so maybe log in from a pc and see if you got lucky.
Update 2/15
Okay so my g3 was hard bricked I sent it to factory, they replaced the internal storage and sent me back same phone (I checked IMIE) It came updated so It was patched. I downgraded it and rooted it again I put latest version on TWRP and now I'll be paying closer attention to what I flash and don't flash. Thank you guys for your support and trying to help me. I really appreciate it.
Guess who hard bricked his phone again?
So this is kinda a rant because I went where I was supposed to go this time and I read for the most part but again error in the posts and forums. I went to the reference guide and was looking for a stock version of lollipop (I didn't know it hasn't come out yet)

install another rom so everything is good in the hood, wipe cache and reboot
I check my phone and nothing. It's hard bricked. THE F***king base band bricked my phone. I have to send my phone to factory again if they do it for free, most likely not because this is my second time. then if they do, i have to pay shipping and handling, then pay someone to unlock the sim because im not on tmobile anymore I'm on cricket :/ Not everyone here is an expert on all of this, i understand its no ones fault but my own but **** when i go here i think these guys are pros and experts on mods,roms,etc. when a legitimate post is stabled and says its the guide i expect it to be right and not have to worry.

This ROM no longer support my variant since 2.0? I'm using D850/D851/LS990/VS985, can I flash this Lollipop version?
- No, you guys cant use this Lollipop version (2.0). You must wait till LG release official ROM for your variant first to have new kernel & baseband.
- Anyway, if you wanna use my KitKat ROM, you can get it (version 1.2) here: http://forum.xda-developers.com/devd...6315#downloads

I guess you paid the price for rushing thru the process. Sometimes we get caught up in the moment. Its been clear for days, weeks and months that stock LP for TMO G3 has not been released and much development is hinging on that release. I myself have been rooting phones/tablets for years and been fortunate not to make mistakes (or catch myself in time before doing so) and never even had a soft brick experience to date. I hope you got it sorted out

Blu Advance 4.0 L A010U ROMs

Hey guys,
I really need to find at least the stock ROM for the new-ish Blu Advance 4.0L (model A010U), because the most recent OTA update unforgivingly bricked mine. Now I want to try to re-flash the stock ROM, but I am also open to custom ROMs, if there are any available. Please help me out! Thanks in advance
I am really surprised no one has replied yet, but again I am facing the same problem and I've been searching the Internet for one month now and I found absolutely nothing for this phone (specifically for version A010U).
So I am going to post a different question in the hopes that someone will read it and help us out:
I have two Blu Advance 4.0 L A010U phones, which are identical except for the color (white and green). They were manufactured a month apart one in 10/2015 and one in 9/2015.
Unfortunately after only a couple of months of light use and for no apparent reason (did not drop it, or wet it, etc) it started going through a boot loop. It will start, show the "bold like us" logo then restart again without making it to the operating system at all. Like I said I've been looking for over a month to find a ROM (stock or modded) to reflash but with no luck. Then I had an idea. Since I have the other identical phone that's working fine, is there a trick I can do using the working phone to create a ROM that I can use in my broken one. By the way, the non working phone will allow me to get into the recovery menu, but unfortunately nothing happens if I wipe the cache or even if I reset to factory defaults.
Anyone knows what's causing that "boot loop", how to fix it and where to find a ROM or even "extract" or "create" one using a working Advance 4.0 L ???
Thank you very much!
Man I wish I knew. I'm kinda a novice. I have the same phone with a similar problem... I downloaded the recent ota update and the first time it said it couldn't unzip it. I tried again and it seemed to work but when it rebooted into recovery it said there was an error... So it won't boot up, it just goes to the screen that says "no command". I'm pretty sure the there's a way to make a copy of the working ROM but since I don't use a PC for anything I've never taken the time to learn the method.

I just got ahold of a couple of these devices myself and am in the process of going through all the in's and out's of them....I'm a Samsung nerd so I haven't messed with something like these in a while but I got one (that was supposedly dead bricked per the lady friend of mine I got them from) at least able to boot into factory mode and recovery via ADB and just as I'm posting this I'm in adb shell going through the device's internal memory.....so we'll see what all I find and can pull out of this one and possibly know enough to post an intelligible reply with solutions next time
The boot looping sounds like a common problem with these and when I get to that point I'm going to get rid of the stock bootanimation.zip ASAP and try something else. I get the idea that these things aren't exactly power houses built for much so the littlest thing or small bug in their coding could lead to this kind of crap happening.
Hopefully you figure yours out before I toss these out the window! lol
Cheers y salud!

Forgot to add a couple things about your post, sorry! I beleive (and I just started digging into this phone) that the no command part is the locked bootloader these phones appear to have. I think it was a combo of holding both volume buttons down from a powered off state then pressing power button on that came up with the option for factory mode or recovery (which led to the sad 'no command' droid), i went into factory mode and theres an option for Tp Upgrade which Im assuming is F/W or something similar but I just hooked up to the PC and in that mode it's reading the internal and external memory of the phone and that's about where I'm at so far.
Wow! I'm surprised this thread is still going.
Anywho, I found a repository that is storing the default ROM for the 4.0L. The files were just added recently. I would have liked to have seen a custom Lollipop ROM made by now, but this device is far too irrelevant to get any attention, unfortunately. Just root and forget, I guess.
I can't wait to try it, thank you! And btw, were you able to get root successfully and if so, how?

Hey Deuler93 -
You have my respect for digging out that BLU ROMs link and sharing with the rest of us. I downloaded the one for my Advance and used SP flash tool to flash the phone that was stuck on a boot-loop. Of course first I had to download and install the MediaTeK drivers for USB connectivity with my PC. Everything worked flawlessly, no glitches what so ever. All these links are easily found and widely available online if anyone is interested I can share here too. I just hope that this boot-loop was due to some software glitch and not hardware failure. Everything seems to work fine for now, keepint my fingers crossed it will NOT happen again.
Well, one less headache to worry about. By the way we're not that far, if you're ever in the Chicago area, I owe you a beer or something. Thank you!
Hi guys !
Thank you very much for the Advance 4.0L Roms.
I have successfuly recovered my phone, but the IMEI got lost.
So, I need to root it in order to recover the IMEI, but I just can´t get success on any method :
Kingroot
Framaroot
Towelroot
is there another way to root it ?
Thank you very much.
I got temporary root using the kingroot apk. But it messed things up and I don't trust it anymore. None of the other mentioned methods worked for me either, maybe try the PC kingroot method
well this helps one thing

umm. . . when the no command option comes up just press the power button and the rest of options will appear. doesnt exactly solve your problem however unless you have the ZIP file to install, which is what I'm looking for.
What might happen if a ROM is used for another blu phone. ??
A similar phone as well.
Plz advise.
Damn! This thread just keeps going!
I haven't even looked here in a while, so I will bunch my commentary here. I'm also salaried now, so I bought into a OnePlus X (onyx), a more expensive cheapo device, so I do not use the 4.0L anymore.
As for rooting tools, I used the Kingroot APK successfully in the stock environment. I never tried flashing something SuperSU myself, but it could work. Is flashing a SU app possible from the fastboot interface?
And to Steve's question - it is technically possible to flash a ROM for a different device onto your own device, but is considered a bad idea due to the possibility of introducing incompatibilities and missing proprietary requirements. I feel like this would hold especially true to stock ROMs because the manufacturer probably has no interest in supporting anything more than the device that they are manufacturing for. Doing so removes many possible "compatibility" issues from even having to be considered, but I digress. In short, try to find a ROM made for your device and your device only.
Did you find the zip file for the recovery

You dont need root to recover imei all you have to do is type *#*#84666364#*#* in your dialer and you will be entered in EngineerMode then go into connectivity ,CDS information and radio information phone 1 or 2 then you will see AT+ type something eg.A then backspace and select the first thing you see. Put a space after AT+ and then put you imei code here "IMEI" between these "" You can find your imei by removing your battery it willl be there. After sending command reboot and imei is back.

Hey guys, links here seems to be down .
Maybe this link would be useful for you all... stock firmware can be downloaded and useful help on videos is available too... Enjoy

lg g4 connection to server failed

this is the error message i get when trying to flash the stock rom onto my lg g4. i bought a phone that had the google account locked out, so i figured i could get around that somehow. when i got to the part where the settings needed accessed in the vision menu, it was greyed out, so i did some more research. this led me to the lg flash tool i used today.
i went to this forum and downloaded all the items needed and installed the drivers, then put the phone into download mode and opened the tool as an administrator. i browsed to the file leaving it at cdma, diag, 33000. i hit cse flash to wipe it and it verified the phone connection. then it said connection to server reset. please try again later and made me exit. i tried again, then this time it it got to upgrading sw and went to 5%, then counted 6, 7, 8, and 9, and then said upgrade stopped due to an error. i have a log if that would help, it looks like it is having trouble extracting the file. i got the US99110c_03.kdz because that is my model of phone, but also tried an 815 in case it was a bad file. any suggestions are much appreciated.
looks like i have figured out what happened. finally, i got a tool started which gave me a thorough error message. it said the new rom was older than the one already there. now, the one dated 28 aug 15 is the newest one i can find anywhere. any ideas where i can find it?
