[Q] MyTouch 4G Boot Loop - myTouch 4G Q&A, Help & Troubleshooting

Now, This may have been answered or tied into the post by neidlinger, however I've found my problem to have some strange symptoms and was wondering if anyone could help me out.
I had my Glacier working just fine using the ice Glacier ROM, decided to try out some new ROMS including a couple Gingerbread roms. I updated Clockwork Recovery to 3.0.2.4 and flashed the roms, they seemed fine, but they weren't my cup-o'-tea. So I flashed back to IceGlacier 1.1.6. Ever since then My phone has had a boot loop issue that seems to be effected or triggered by power management. Not always, but sometimes If I plug my phone into the stock charger or otherwise, it'll reboot and sit there looping at the MyTouch splash screen until I pull the battery. Same happens on occasion when unplugging the phone. I can get it to boot into Android by letting it sit off for a while then come back to it a couple minutes later and power it on. Is there anything totally wrong with my device outside of what neidlinger posted?
Any help or advice will be greatly appreciated, Thanks!

Update!
Update: I found some time finally to look through some roms and flashed "Royal Panache" using CWM recovery 3.0.2.4. I still get the boot loops described above, still related to power, seemingly. If I plug the phone in while it's off, often it will start up on its own. Any help is still greatly appreciated . Please tell me if I'm just being stupid and/or blind.

try changing charger, or use pc charge and see if that happens

Thanks! I'll give it a whirl. Though I will say, it happens when using my car charger which is just a usb port.

You keep mentioning the cwr version as part of the flash process. Have you been reflashing recoveries each time you flash a new rom or something?

I have not, it's just added information. From what I've heard some recoveries only support froyo or only gingerbread.

It still happens when plugging into my pc.

Try restoring your phone to stock using PD15IMG, and see if it takes care of the problem.
If you have engineering bootloader - remember to reflash it after PD15IMG (it'll restore 0.86 stock bootloader when flashed).
If the problem won't be cured - it means that somewhere in your flashes you've probably damaged/overheated something in the phone, and now it needs replacement.

Thank you very much for that bit of info. As soon as I get some time, I'll try that out.

Help! Droid 2 stuck in boot loop.(solved.)

Ok, so I was playing around with the new Root Tools app and made a few, what I thought were safe, tweeks to the system and rebooted the phone. It gets past the M screen, runs the boot animation and then starts the boot animation again. No way out except to pull the battery.
How can I get it out of this endless bootloop? If I have to factory reset and start again from scratch, so be it. I would just like to know how.
I've tried holding down different button combinations on boot but haven't come up with the right sequence I guess.
I've also tried pulling the battery as the animation starts, then putting it back in and rebooting which is supposed to call up the recovery mode, but it doesn't. I'm not sure what to try next? I wish these things had a reset button
It's a Droid 2 Rooted with the stock rom running Froyo 2.2. I have the Bootstrap recovery loaded and did a backup with the clockwork recovery. I also have, and use, Titanium Backup Pro for Root.
After bootlooping pull the battery and put it back in. Then plug the droid 2 in with the cable either wall or USB will work. Then turn it on and it should get you recovery. The phone has to be completely off when you plug it in though.

EDIT: I tested it and USB won't work (at least for me) better off just using the wall plug.
Thanks, but that not working either. When I plug in the cable after the battery pull it starts up automatically and goes to the battery charge screen. I then shut it off and start it back up with no battery but plugged in and it goes right back into the boot loop after the M screen.
The batter charge screen is what you want. Just press the power button after you get the charge screen and you'll be booted into clockwork.
But in order to factory reset from a bootloop you have to flash an .sbf theres a few different tutorials. One in Windows, Another in linux/mac, and another in linux but for windows machines through an Ubuntu livecd(that I made).
Oh, OK I thought it was going to go right into recovery mode. Good to know.
I finally figured out how to get into the stock recovery and bootloader, so I tried to run the stock restore but after it wiped the data, it couldn't find the recovery file! So then I read in another post about using RSDlight 4.9 to do an sdf restore so I used that method. Of course while it was flashing I did come across your Ubuntu method and that does look like it would be a simpler process. I'm going make one of those CD's to have for next time.
Anyway, I was able to get it back to stock. It looks like most of my stuff is still on the SD card, so that's a bonus! I'll have to re-root before I can restore everything via Titanium, but that's going to be tomorrow's project. As for now just happy to to have my phone back. Especially before the wife (who has been telling me for weeks to stop F'in with it) found out .
I really appreciate that you took the time to help, thanks again!
No problem.

[Q] MyTouch 4g: Multiple problems... PLEASE help.

Okay, I've searched and searched and no one seems to have the specific problem that I'm having with my phone, so I'm taking to the forums myself. I've been rooting since the G1, I know how to adb push things, I have used google and multiple forums to try to fix this problem. So here goes, anyone that can help I thank you in advance.
1-My phone, like some other MT4G users, reboots itself each time it's plugged in. Initially I thought this was because I was using a Kindle cord to plug it into the pc, so I bought an MT4G usb cable from tmobile, and still it boot loops (just the first white screen for maybe 4 seconds, then black then again and again). The only way to charge it is to let it start boot looping, take the battery out, turn it on, and if I'm lucky enough that it begins to boot up correctly I plug it in mid boot. If I wait til it's fulled loaded it just starts rebooting again.
2-It will not at all from any angle go into Recovery mode. If I try to go to recovery from Rom Manager, or from the screen you get when holding power and lower volume key or by flashing a rom through Rom Manager, it just boot loops just like mentioned above, until I pull the battery for a while (it is currently sitting next to me with the battery out) and then put it back in.
3-If by chance it's on, and plugged into the computer, it is not at all recognized. Ever. While it's booting up my computer finds something, but doesn't know what it is, and doesn't allow me to view any folders on the SD card. Yes I've installed the HTC drivers file. I've adb'ed things to this phone before, now it says device not found. I don't know when it stopped being recognized...
4-I've even tried to fastboot something over to it, but to no avail, still not found.
If I try to do a factory reset, it boot loops. If I sneeze it boot loops.... I don't know what to do, and if I trade it in under warranty, I have to reset it to stock rom, or they're going to charge me for a new phone. Any ideas!?
I have Cyanogen mod 7 on here.
have you tried a fastboot wipe? or have you tried to reboot to recovery from adb?
First, I don't trust using the actual ROM Manager app to do the flashing/installing.
Since you've been flashing since the G1 days why not use Clockwork Recovery? Just go into recovery and do the necessary wipes.
So I suggest to do a complete full wipe in Clockwork, meaning wipe data, cache, and dalvik cache. Install the newest CM nightly (Which is working wonderfully BTW) and see if your problems still persists.
Edit: I didn't realize you tried to enter recovery, oops. But yeah try what the buy above me said. Try re-installing the latest CWM recovery, if that still fails then try heading into there via ADB.

I second that, flashing ROMs from ROM Manager a terrible idea.
Well...if all else fails and if you are really thinking about returning it and still under warranty...few seconds in the microwave method should work just fine. They wont be able to see that its rooted if the phone wouldn't turn on, would they???
glimmer of hope...
So by the grace of god I did get it flashed back to unrooted, stock 2.2 by putting it as pd15img.zip on my sd card and going into bootloader. Once that was done I thought I would be out of the woods... I even plugged it in last night and no boot loop!! but this morning I unpllugged it (and I'm using a tmobile cable for the phone attached to my pc) and here it sits, next to me again with the battery out of it because everytime I try to turn it on (for over 40 minutes now) it boot loops to that stupid white screen (that is honestly driving me insane at this point). I know that it isn't rooted (because I dl'ed rom manager and it won't let me do anything without being rooted) so do we think that I'm safe to go to the store today to request a new one be sent? Thoughts? And thanks for the help thus far!
yeah I would send that back
Bad emmc chip? I'm sorry man, that's a terrible story.

[Q] Boot loop but can get into recover and flash

OK heres the deal. I have done tons of searching and it looks like I SHOULD be able to get out of this, but I cant figure it out and I may have gone to far(by unrooting with 4.24 and bootloader 2.16).
So long story short, my launch day evo got lost about a month after I got it. Got a replacement from Sprint(or whoever their insurance is), my original Evo got found about a month or so after that. It has not been powered on since then(a year realistically) with no battery or SD card in it. I got bored and decided to power it up and update everything(because I cant do **** with my new Evo3d, yet since im on a Mac and have no access to a PC). Here are where things went bad.
Phone was rooted with the very original Toast method including S-off with the .76 Eng boot loader. I was running some form of CM6 on it when I lost it.
-Went to power it up and it boot looped at the white Evo4g screen.
-Went into bootloader and tried to get into recovery(had Amon RA 1.7 I think). No go.
-Flashed the new TWRP recovery and got into recovery just fine.
-Flashed the CM7.1.0-RC1
-reboot into a boot loop
-battery pull and a reboot and it loaded, but after about 30 seconds, reboot into a boot loop.
-Thought maybe TWRP didnt like the phone so I flashed Amon RA 2.3
-went into recovery just fine. Did complete wipes of everything using Calkulin Wipe all.zip
-re-flashed CM7.1.0 RC1
-boot loop
-flashed latest radios
-rebooted back into recovery
-reflashed cm7.1.0 rc1
-boot loop
During all of the reboots I would occasionally get the CM7 splash screen and then a reboot into boot loops. I THINK everything was flashing ok.
At this point I was frustrated and was thinking it was something I was doing that was jacked up so I decided to unroot and I flashed the newest RUU(which obviously removes root, S-off, .76 boot loader, etc...) so I did it. Figured I was just trying to get the phone running to sell anyway. Flashed was successful, chose to reboot and guess what. Boot loop. I pulled the battery out for about 10 minutes and it boots into the rom, runs for about 10-15 seconds in the rom and then reboots, back into the rom at least, but only about 10-15 seconds later, another reboot.
Every thread I read on these infinite boot loops were guys saying they couldnt even get into recovery or flash anything, which I had no problem doing(obviously cant really do that anymore with losing root and s-off). So I am stuck.
So current state of the phone is boot loader 2.16 S-on with 4.24.651.1 with all current radios, etc... flashed(as far as I can tell) from the RUU posted on Goo-inside.me.
Does anybody have any ideas for me to try? It seems like I am so close to getting it running because it will run for about 60 seconds but then reboot. I am guessing a hardware issue, but I honestly at this point have no clue.
Sounds like a hardware issue to me.

Thats what I am leaning towards, but why, if a hardware issue, will the phone run in the boot loader or recovery for basically forever without rebooting? It will also successfully(or did) flash everything I asked it to. I would think it would always reboot around that 60 second time frame if it was a hardware issue.
damn, too bad you ran RUU & lost s-off. now you couldn't do anything to test/troubleshoot even if you wanted to.

I know. I probably should have posted up and waited, but I got impatient and thought that was a last ditch effort anyway since I tried everything else I knew to try.

because in the boot loader and recovery menu I'm sure the phone is not accessing radios, audio components, gps, and all manner of other hardware components that get activated once the phone tries to boot up for real.
It sounds like according to this thread: http://forum.xda-developers.com/showthread.php?t=805612&page=4
That my NV is FUBAR, but since I ran RUU and lost S-off, I cant do the fix. Oh well, I am sure eventually somebody will crack the boot loader and then I can fix it. Otherwise I have to send it off to HTC and I am sure pay them to fix it.
Just to clarify. The thread you linked to is for people who wrote nv items to their device.
What I'm afraid you are experiencing is the bootloop commonly complained about by those running CM roms.
I have yet to find a solution to the CM bootloop and all signs point to hardware failure.

Boot loop not past Evo Splash screen

I know this is a known issue but I wanted to see if anyone has had any luck yet.
My phone only gets to the HTC Evo splash screen and reboots. I can get into hboot and when i choose recovery from hboot it goes back into the boot loop.
This just happened to me a few days ago. I went from MikG to Deck to CM7. I just flashed CM7 over Decks 1.3 wiping only cache and dalvik. I was starting to really dig CM7 and I was planning on sticking with it. When it happened I was using the stock web aplication. I finished reading the page I was on and hit the back button (the one at the bottom of the phone) and next thing I knew my phone started rebooting. It never made it past the Evo splash screen since. I've been able to flash different hboots and it takes but it does not take any of the recoveries or RUUs. Has anyone had any luck with this yet? Or does anyone have any different advice with the extra info I have provided?
To reiterate I cannot get into recovery only hboot.
Thanks a ton in advance all.

To thee root of your SD card and then boot into HBOOT to load it.
Make sure it is named PC36IMG.zip
You may be missing your recovery.

I appreciate the link but my issue is that I can flash the recovery files from hboot but to my dismay I still cannot get to recovery from the recovery selection within hboot. There seems to be an issue where hboot hands the reins off to recovery or android. I'm not sure how to troubleshoot or overcome something like that. Maybe my assumption is wrong but who knows.
You don't have to go into recovery to flash a pc36img. It happens in Hboot.
In theory, you should be able to flash that, then flash recovery.

Is the link provided not Amra recovery? That is what it looks like to me, but I could be wrong. Please advise. I can flash the recoveries in hboot but when i go to recovery from the hboot screen and select it the boot loops commence.
Unfortunately, that is a problem that you can search and see a fair number of people have had and I don't think anyone has fixed it as it means bad blocks and/or something to do with partitions being resized and I hate to even say this, but all but a very few cases were running CM7

I wish i could flash it back to stock so i could use it again. I paid $200 for this thing. I'd like to get a few more years out of it. Nothing like the OG. I've tried running the RUU files from windows while in hboot and the files do change as I flash different versions. I noticed this when during the ruu program it shows you the from/to screen. So I know the RUU programs are working, it's just that the hboot recovery/ROM handshake is not happening. I guess I'm hosed ATM.

[Q] phone wont boot or charge?????

Just picked the phone up yesterday. Not new to the mt4g but they said it was a software issue so I was like hell that's an easy fix. Got it to flash the pd5img but still has a amber light that blinks 7 times then tries to boot but it loops at the mt4g splash screen. Anyone know a fix for this? Can boot into the boot loader but can't do much cause the battery won't charge. Prolly need a new battery but if anyone knows how to force charge let me know.
edit: tried charging the phone by blocking off the middle two contacts on the battery. that got the orange light to stop blinking and i managed to get the pdimg to install again but still loops... it installed everything fine it skipped one of the tp's but the other one did its thing. guy i got the phone from said it wouldn't start up for him it was a software problem he assumed and put it in a drawer for like 3 months so the battery is completely drained. gonna keep the other two pins on the battery blocked for 30 minutes or so to see if it will boot. fast boot kept throwing me a error about the battery not having enough voltage to install the pd15img.zip update so battery might be toast not sure will keep everyone posted. any ideas just throw them my way
Edit: OK got the battery to charge and no voltage errors in hboot anymore but can't boot to recovery or factory reset the device. Is hboot screwed? If so how would I flash another without being able to use they phone?

no errors flashing the emmc chip i would guess is good still because it flashed. I've already read the q&a sticky about this stuff and nothing is helpful. phone is stock as far as i know. before i flashed the pd15img i looked at the radio it was the same one from the zip and the phone still had s-on i got it from some guy that looks like he wouldn't root or anything since he had an iPhone... and like i said hoot said s-on and had the latest radio so i would assume everything was stock. might be the battery but i won't charge every time i connect the phone to the charger it tries to boot and ends up looping at the mt4g splash screen. ill try another battery tomorrow when i get a chance to swap it from my brothers girlfriends phone. but I'm working a 24 hour shift today so i have plenty of time to mess around with this phone so i figured i would
ok i can get into fast boot but can't do much since i have s-on but if anybody has an idea please let me know id like to come back to the mt4g
To save yourself the time, you could try HTCDev unlocking it and installing recovery by fastboot, since the warranty on the phone is long gone anyway. This might allow you to try flashing ROMs from recovery. Don't forget to flash boot.img from fastboot though!
If this route brings your phone alive, you can try to relock and S-OFF the thing, to have normal flashing access from recovery.

I did HTC dev but when I tried to flash stock boot.img or recovery it didn't wanna work saying that the boot loader was locked which is weird since its supposed to be unlocked
Anyone have any ideas?
