Help! Phone crashes after booting OS! - G2 and Desire Z Q&A, Help & Troubleshooting

Well, this sucks. Upgraded from the Hero to the Desire Z 1.5 weeks ago. Downgraded it, rooted it, tried out a few ROMs, settled on Virtuous Unity and all was happy.
I used the phone in the car this morning as a GPS, 3G data connection was working fine, etc. I had a couple of client meetings, after which I pulled out my phone to check for messages. I noticed there was no mobile signal at all. I figured it was building interference, so I went outside. Still nothing. Wifi was working fine, GPS was working fine. I enabled airplane mode, then disabled it again to see if that would kickstart things. Still no go.
I decided then to power cycle the phone to see if that would help. It went through the usual reboot cycle, displayed the lock screen, then the SIM unlock screen. Then no matter what I do or don't do, about 5 or 6 seconds later, the screen suddenly goes black and the phone reboots.
Now it just does the same thing over and over again. The phone boots up fine, displays the lock screen briefly, then the SIM unlock screen, then it crashes and reboots. Whether I unlock the SIM or not doesn't matter. Within 5 or 6 seconds, the phone will reboot. I can see notification icons popping up, so everything appears to be working fine otherwise.
I have not changed anything on the phone this morning: it was sitting in my pocket the entire time. Same ROM, same radio firmware. I restored last night's nandroid backup just in case, but it didn't help. I thought perhaps it was VU's built-in overclocking that wasn't agreeing with the phone, so I restored a MIUI-based backup. No go. I went all the way back to the stock (but rooted) Bell Desire Z image I took when I first got the phone. Still no go.
I've tried booting up without the SIM card, and without the SD card. Nothing works. I'm guessing the phone suddenly developed a hardware problem. It would be something that is triggered soon after the OS has successfully loaded. Maybe something to do with the 3G radio?
There are no obvious errors or kernel panic messages in logcat. Everything appears to be proceeding normally, until it just comes to a dead stop. Anyone have other suggestions I can try?

Search this forum for "boot loop" and you'll find some things to try.

Thanks, burtcom, but none of the threads I checked apply here. Other boot loop problems more often have to do with the phone rebooting while the boot animation is still playing. My phone successfully boots and is in the process of loading user apps when it crashes. Also, most reports come as a result of something attempting to root their phone and then installing a ROM. I've already made it past that stage. I am able to boot into CWM, do my nandroid backups and restores, etc. The ROMs have all been working fine up until some point this morning. The fact that several different ROMs now all have the same problem makes me suspect a hardware issue.

Moved my SIM and SD card back over to my Hero, and everything works fine there, so I strongly suspect some hardware just broke on the DZ this morning. I'll try flashing a new radio firmware, but I can't see how that would fix anything, since the old version was working just fine all along.

taob;15238893I'll try flashing a new radio firmware said:
Huh... so I flashed the latest Bell Canada 26.06.02.25_m2 radio.img, (up from my old 26.03.02.18_m3 firmware), and now the phone no longer crashes. I'm thinking maybe it isn't an issue with old vs new firmware, but that the old firmware was somehow corrupted during the course of the day. Re-flashing the original radio probably would have worked too, but now I have the latest one...
Hopefully this will help someone in the future with the same problem.

The phone no longer reboots, but I still had the problem of not picking up any signal whatsoever (voice or data), even though wifi and GPS work just fine. APN settings were verified to be correct. It turns out I had to go into Settings -> Wireless & networks -> Mobile networks -> Network operators -> Search network and manually re-register my phone on TELUS. Bizarre.

I had the same problem, update your radio and flash this zip on the Unity Thread
"For people experiencing random phone Freezes, this is due to overclocking, it's solved by lowering max speed.
Just flash this patch over: (link is on the thread)"

That's a different kind of problem, sengalang. My phone was working just fine overclocked to 1.2 GHz for over a weeks, so why would it suddenly start crashing like this? Problems due to overclocking tend to result in reboots at random times, and not at 100% predictable times like my problem. I did also boot with the MIUI and stock DZ ROMs, which do not overclock... same problem. Thus the root cause was not CPU speed.

Anyone got anys ideas on whats wrong with my TP2???

I have been using the Energy Leo Rom’s since September updating whenever I new rom is released, everything has always been fine with them and I absolutely love them. Me and my fiancée both use them, but lately my phone has been restarting over and over and will not boot, it gets to you boot up splash screen and restarts. When this began to happen I wasn’t even using my phone it was recharging as I was updating my computer to Windows 7, anyway I am able to revert back to T-mo’s stock rom and everything works, but whenever I go back to any none stock rom, even earlier ones it keeps doing the reboot thing, our second TP2 is fine. I have done research and haven’t found much I have ran Mtty at least a dozen times, even upgraded my radio, and nothing works but the stock rom, I have cleared storage both the software route, and the power, talk and end button route. Any help would be greatly appreciated, I just can’t handle this stock rom.

Are you able to re-do the Hard spl?
Yes, I have redone it and nothing changed, it goes through the initial TP2 screen showing the radio and other info in red on the bottom, but as soon as it goes to set up the rom is when it restarts. Whats weird is it is never at the exact same time, sometimes will be a second, other up to five seconds.

I know this sounds obvious and dont take it the wrong way but are you sure that the rom you are trying to flash as been unzipped properly and is named correctly. Try re-downloading a fresh rom and unzip it and rename it Rhodimg.nbh and put it on the root of your Sd card and try flashing it from the card. Also is the battery charged?
I am certain that the roms that I have been using are unzipped and named properly, there was actually a flahed rom on this phone that was workig fine until it started resetting with the rom on it, I wasn't updating or anything when it started to act up. Plus I use the same roms on a second TP2 which are working fine. I did try now to flash from my SD card, Hard SPL said it installed correctly but when I rebooted phone its doing the restart thing over and over still. Battery has been at 100% or close to for all flashes.

phone is acting weird

Well my phone has been acting weird recently. It seemed right after I upgraded to radio 4.49.25.77 as well as upgrade to cell evo 7.5 (http://forum.xda-developers.com/showthread.php?t=622883) now when in the os it seems unresponsive and acts weird as well as it is unable to boot now. (it booted fine for a while until now) Is it the radio i flashed bad or what? Ive tried a different rom as well and it turns out the same.
All it does it gives me the white att screen, then the red info comes up. then the screen dims a bit and freezes.
Any ideas? thanks
change radios and see what happens

Tried, changed from that to 4.49.25.91 and no go.
Could it be the device is corrupt? I flashed back to orig radio and then tried to restore the phone by hitting the power + end and start and it does the same thing.
did you install any applications after you flashed the device? you mentioned that it worked fine for a while and then the issues started. Sometimes, applications conflict with one another and either the phone freezes or one of the conflicting applications become unusable. I would try to recreate step by step any applications you may have installed to identify the culprit.
hard reset.

HTC Desire Reboot Loop Problem

I have an interesting problem, kind of. Bought my phone second hand as supposedly unlocked & debranded but on boot up it after the HTC logo I get the Virgin Media logo, not really an issue though. Anyway the problem is when I switch the phone off and then switch on again it boots up fine to the home screen and then it will reboot itself and carries on doing this. i.e. boot up to home screen then reboot again continuously.
To get out of this reboot loop I have to remove the sim & boot the phone with no sim in it then switch off and insert my normal Vodafone phone sim and switch on again. after that the phone is fine until I power down and then the same thing happens.
Anybody else experienced this or got any ideas?? It came with 1.15.405.4 firmware already installed and I have tried reflashing with the same firmware using the goldcard method & it worked but the problem remains. When the sim registers on the network is when the reboot loop seems to start.
did you try reflashing it ?
hold down the side button (down) and press on at the same time.
then select erase data and press on again
if you bought it second hand, its hard to say what the previous user has done with it ...
Yep tried reflashing it, just about to reflash again with an older rom. It's just wierd that a sim card authenticating to the network would cause a reboot loop.

Maybe it's a dumb question - But I'm having some issues that doesn't seem to get solved by a factory reset - Would it be an idea to reflash it for this, so the phone gets a fresh rom?
How would I do it specifically? Do you know of a guide somewhere?

have you tried a different sim card ?
Ye tried a different sim card, boots fine and all is good till you reboot the phone and then the same happens again. Anyways flashing was a disaster this time round as I was doing it on my work pc and Symantec kicked in thinking it found a virus with adb.exe and halted the process & quarrantined the file. Now everytime I try and reflash on a different PC I get the dreaded error(110):file open error. Disconnect the phone & all I get is a black screen & HTC logo. Nice. Thanks Symantec you've just bricked my Desire!!
*UPDATE* - Fixed.
Removed the battery, left it for a few hours then reflashed on a different pc and it flashed fine. Then thought I'd try & repeat so reflashed with the older rom from here (originally used the newer rom posted on Modaco) and got the error again and again couldn't flash back to the newer. Removed the battery left for an hour and then could reflash again and get it working!! Wierd
I had the same problem.
My Solution: remove battery, remove the SIM, put battery reboot, turnoff, remove battery, put SIM, put battery, boot
first i want to excuse my bad english,hope you will undestand what i´m trying to say.
i have the same problem since a few days.
first time i notice it,was when the desire was charching and i used it a bit,it restarts again and again.so i put out the battery and wait a few minutes,than it works.
it´s also,when i use it a long time with wifi or 3G....the the phone turns off and i have the boot loop.
but when i take out my sim,it works fine.
my question is,do i need a new sim or is it a hardware problem?
does anybody know?

sorry, wrong thread

i have the exact same problem!! any solution? after that the phone will boot loop over and over! damn!
I had the same problem last week.
I suspected it had to do with the EXT3 partition.
Solved it by first flashing the OTA 2.2 ROM (for rooted users) as this does not use the EXT3. Then used Rom manager to recreate the EXT3.
Now all ROMs that use the EXT3 run fine!
hmmp
as long as i know, i did not install anything on my phone lately so thats the problem so far and i think tequila98 also having the same problem as me, cause when i remove my sim card the phone works fine. but ive reset my phone yesterday and not restarting so far hope this will continue.
I really wished there was a dead fix to this problem we are all having!
My problem:
My phone was running fine until a few weeks ago. There was no rebooting problems when I first got my phone (April) and when I flashed my phone for the first time (May). Happened a few weeks ago when I was browsing on YouTube where my phone suddenly restarted on it's own.
Before it was once a couple of days, now it has gotten more frequent and annoying.
I don't think the heat is the problem because I don't go on the internet much because of my data plan. I use wifi when I browse the web, youtube, etc. And I certainly don't use Google maps or any heavy duty applications. That's just what I think...
My phone rebooted 3 times today in a time span of 4 hours? I noticed that my phone rebooted itself when I use the camera to take a picture or video. Doesn't happen everytime, but that's what happened today. Also, when my phone rebooted today, my application Advanced Task Killer was automatically removed from my phone! That was weird... But I experienced another reboot even after having the app removed.
I really hope someone can find the core of this problem and fix it!
My phone is running on DeFroST 2.0b Android 2.2
My battery stats: 42% for display, 26% for cell standby, 21% for phone idle, 4% for android system, 3% for voice calls, 2% for android OS

It's probably hardware problem with motherboard. Therefore I recommend you to take your phone to repair center and they should replace mobo with new one. That's what I did and now everything is ok.
I am having the exact same problem. Seems to be related to the SIM.
But the SIM works fine in another phone.
Did anyone find any more information?
If you get random reboots its most likely ther motherboard there is a massive thread about it on the forums. You need to send it off to a HTC repair centre.
Just got this problem.
I rooted yesterday. Today I made a nandroid backup. After that the phone is in a reboot loop.
How is this possible from just and backup???
Tnx.

Edit:
Restored backup and is working fine again.

2.29.405.2 update bugfest - any way to roll back?

Did the 2.29.405.2 update OTA initially and noticed problems. So reinstalled it from SD card but no help.
Bought sim free, unbranded/locked and never rooted:
Cannot dial out from phone lists or contacts. Going to phone and clicking on an entry in the call list does not launch phone call any more. Going to contacts, opening one and clicking on an available phone number does not launch phone any more.
The only way I can make a call is to punch it in on the keypad! Grrr.
Wifi connects to my home base after a reboot but, after an undetermined amount of time it drops the connection and cannot get it again. Going to Wifi settings shows it scans, connects and tries to obtain IP address. After a short time it gives up, turns wifi off and starts over. Again & again.
Cannot get it to connect again without another reboot.
This is a crippling loss of functionality for me. Can anyone suggest a way to roll back this update so my phone works as id did?
Many thanks all,
M1
First try a hard rest(you will lose all personal data on the phone,pictures and other stuff on the SD will be fine). If that does not work try either the 2.29.405.2 or 2.10.405.2 RUU.
More info - to my horror, around 15 minutes after I had tried and failed to make calls from contacts the phone started making them one after the other as if they were stuck in a spool or something! Ouch - any thoughts?
Backup everything you can and flash the same ruu from shipped roms.

Thanks to all for help on this. Decided worth a trouble shoot before a hard reset and culprit seems to have been an app - extended controls widget. Removed this and all seems well again.
Try this one. This definately works! i have used it.

I was stuck at 2.29 update.
Then i used this guide and windows tool.
So i did this process and it rolled my phone back to stock android 2.1 rom 1.X
The first version that the phone was bought with.
This tool will boot the phone into bootloader and load a stock 1.x rom ota off the sd card as the tool will extract it to sd card and then load it.
This will wipe all your data not sure about the sd card as i dont remember any of that because i formatted my sd card after i had used the tool.
Thats because i had rooted my phone and tried custom sense hd rom.
The only reason i had was of the battery usage as the consumption was very badly increased and that the 2.29 rom was unstable.
PS: I did first try the htc service in Denmark. They couldn't help me and said i was stuck with the 2.29 rom update. :/
After my phone got rolled/flashed back to stock android 2.1.
The next day in the morning i could upgrade again to android 2.2 rom ver. 2.10 OTA from htc servers.
Maybe this works for you as i did for me and others.
Turns out it wasn't the app.
After a couple of days playing ok my sim free stock htc desire is unstable again.
Cut me off mid call - went to phone and clicked on last call entry - absolutely nothing happened, repeated with same problem. Exited phone to home screen then opened contacts and tried to make call from there - same behavior, a complete hang.
No web access either so opened wifi manager to find it hanging on "obtaining IP address" from my home network and continually shutting down and restarting wifi automatically at this stage.
Noticed general UI lag and several apps failing to open too.
Left phone alone and again, around 10 minutes later all of the actions - including trying to make the phone calls started running one after the other. Like everything had been caught in a spool or something. After this all seemed OK until it happened all over again later.
Although the UI seemed OK and some apps worked as expected, the only way to get phone and wifi working whilst it was hung was a warm boot.
Dreading a hard reset as it's going to waste another day or two getting everything reconfigured just so (can't find a back up solution that does everything - multiple mail account settings etc) but looks like only option.
Will try going back to mikep99's suggested rom as soon as I have time and will not be responding to an HTC OTA auto update offer again.
Grrr.
I still suspect an app conflict.
Can anyone recommend a util that might give me a clue which app / sys process could be hogging system / radio resources?
just got another OTA update pushed to me. installed (nothing to loose) and Congratulations my phone has been updated to 2.29.405.5.
Not sure whats going on here as that was the update I got 2 days ago. This time round it was only 4.8mb download so I'm assuming it's an update update. Hope it fixes things .....

[Q] Desire seems to restart when using 3G

I've been using my desire for about 1 year now and never had any problems until I decided to go back to Leedroid gingerbread rom and install the patches for A2SD+ with ext 3.
I was having restarts every 10-15 minutes on Leedroid, went back to CM7, currently on cm7 7.0.2 and I'm still getting restarts when I wasn't previously.
I have asked this question before and thought it was an issue with the SD card. Now the reason I thought it was the SD was when I was having loops of restarts I would take it out and it would be quite stable for a while. Formatted everything (SD and internal + cache) put on the latest radio rom and then put on the latest CM. Seemed to run fine for a while and then started restarting again. It locks up on the HTC screen occasionally and requires me to pull the battery.
I've noticed that it only happens when I'm using 3G internet connectivity. Just recently it tried to get a lot of updates and would start downloading them only to restart. It does eventually get the updates though.
To test this I can start watching a youtube video and it will crash. For example I just watched 1 minute of one video before it crashed, after reboot I started youtube again and it crashed immediately.
Can I stop log cat removing all the logs when the device restarts so I can have a look what's going on? Any other ideas on how to diagnose or fix would be much appreciated.
What's your radio?
My Radio version is
32.56.00.32U_5.17.05.23 and I'm running CynogenMod 7.0.3
I used something else before I switched to leedroid an old one, I changed it to go to Leedroid then changed it to this hoping it would help.

RIL (by System of a pWne!^)
Radio interface layer. This is a layer between the Radio and the ROM. It communicates with the hardware over the Radio and supplies an interface for the ROM so it can use the hardware. This is similar to a driver.
Whenever you flash a new Radio, you should also consider flashing the corresponding RIL for it. This makes sure, the Radio is getting adressed correctly.

I was running the RIL suggested above yesterday, had about 11 hours and no issues, updated all my apps, was watching youtube etc.. I was trying to do stuff that usually would make it crash. Eventually I turned on my wifi at home and as soon as it came on the phone rebooted. It then proceeded to reboot every time I tried to go on the internet, with either 3g or wifi, I tried about 3-4 times. Leaving it with internet off for about 30 mins, I came back to it and it started working on wifi fine. Strange. TL;DR ril didn't seem to fix it. Seems like if I can get it back to stock I can go to the shop and change it.
