[Q] Infinite Reboot (Hardware or Software)? - myTouch 4G Q&A, Help & Troubleshooting

Hey everyone, I was wondering if someone encountered this issue before and can help me out. My MyTouch 4G has a pretty serious problem, it doesn't really want to boot up. When I power it on, it vibrantes ones, gets into the MyTouch 4G logo, then vibrates again and turns itself on, just to turn itself on a few seconds later and repeats...infinitely. I can always get into fastboot to flash the PD15IMG.zip using the volume down button but once it's done it does the same.
Now that's not saying it never boots up ever. Once in a long while of rebooting infinitely, sometimes I noticed if I leave it there it actually does boot properly and once that happens, it works just fine. However, if I ever turn it off fully (battery pull or turn off fasboot and power down), it does the same infinite boot loop with a small chance of booting successfully.
The phone did this when it was s-on and s-off, before and after it was unlocked. I was wondering if anyone ever had this issue. At first I thought it was software, but now it seems more like a hardware problem? Is there a sticky key that is being pressed down that is forcing it off each time it is loading?
Any help would be great, thanks!

Well what you will have to do is either flash the PD15IMG and restore back to 100% stock and see if that fixes the problem.
or if you can get into recovery, given you have Clockwork Recovery, is flash a different ROM to see if that helps.

I've tried it using this FILE but the same things happens once it is done and asks me to restart. Clockwork recovery doesn't work, if I choose recovery from fastboot it'll restart to the infinite reboot state.
Also, another problem related to the infinite reboot is that if I plug the phone into the charger, it will start up on its own and infinitely reboot. The only way I can get it to fully turn off is to yank out the battery and leave it unplugged, or turn it off in fastboot while leaving it unplugged. If I plug it in and any given time, the phone will power up on its own.

BUMP! Anyone else ever experience this issue?

I have. to fix it, hold the volume down and power. go into "factory reset" and press power. it should throw you into Clockwork Recovery. Clear out the cache/data then reboot your phone. hope this helps the next guy.

Since this thread was brought up -
For proper way to recover from bootloops or more severe malfunctions, or to determine if the phone requires warranty repair, please read Glacier Wiki, "Troubleshooting" section. Link in my signature.

if you cant fastboot/recovery/anything, it's pretty much bricked. If you get some blue LED, there isnt much hope for that either.
i got no blue led it just stay on the first splash screen no recovery mode or fastboot

Then you're bricked. Means you need a new phone.
no ooo
people there is a solution via the usb when it is stuck at the first splash screen just search
mine is totally bricked and still no solution !!!
call tmobile.
I did the same thing yesterday and I told them that My phone updated itself then wouldnt turn back on.
my new one is in the mail and will be here in 2 days
just act naive and clueless.
as long as your still under warranty, your all good.
thanks ppl i try everything but this its not going no where the pc dosnt want to recognize my phone and i try everything just gonna throug it in the toilet and call the insurence
At least sell it for parts, you can probably squeeze 40 bucks out of it or similar. Check the going rates on eBay for non-functional handsets.
I know its a bit late....but I fixed my 'bricked' MT3G
I was searching around the web for a solution to my problem, and needless to say, there wasn't much out there for me besides the typical... "it's bricked, buy a new phone."
So here's my story:
Earlier today I decided to upgrade my MT3G to Cyanogen's 5.0.7 Android 2.1 rom. I had used the experimental 5.0.6 rom, and found it to be a bit more "glitchy" than I was comfortable with. So, I went online for what I figured to be a very simple upgrade...and downloaded both the rom and a kernel (which was 32A not 32B).
Needless to say, after installing the rom, the kernel, my gapps update, and resetting my phone... it did nothing but hang on the MT3G screen. After about 30-45 min...I knew something was wrong and I freaked. It was unresponsive to multiple attempts to reboot, and was not being seen by my computer.
That's when the online search began... I looked for other individuals who've suffered the same fate and kept coming up with the same "you're screwed" response. Having recovered more "bricked" iPhones in the past than I can count, I knew this could not be the case. For me, as long as the phone turned on and flashed some sort of screen, there's still hope.
So what did I do...
Well, I first attempted to boot the phone into recovery mode...but it would not work. Next, i figured I would try doing a fastboot... and what do ya know... it worked!
From there I used multiple combinations of plugging in the phone via usb and resetting and putting into recovery mode until I found one that worked.
So here's my steps:
(Note: this has only been tested if you accidentally installed the 32A kernel on your 32B device)
1. Power on the phone... If you continuously sit at the green MT3G screen, take off the back and take out the battery.
2. Plug in your USB cable (VERY IMPORTANT, will explain later)
3. Next, replace the battery and hold down both the [home] and [power] buttons, if it merely turns on to the green screen, and you get no response from your computer's usb notification window...take out the battery again
4. Fastboot your phone (hold down [back] and [power] arrows) While your phone in connected to your computer, it should make a notification sound.
5. Restart your phone from Fastboot, AS SOON as it shuts off, hold down the [home] and [power] keys.
6. Continue holding until you hear a notification sound from your computer...at that point it should boot into recovery mode.
7. Wipe your handset (just for good measure) and reinstall your update package...DELETE that wrong kernel from your sd card so you dont make the same mistake again.
Summary:
I have no clue as to why it works, but I've done this 3 times now just to verify, and each time it has worked. For some reason, the USB connection to the handset acts as a precursor to the phone booting. I will stress that without plugging in the USB, my phone did not boot into recovery mode. However, after I did plug it in...Fastbooted....Reset....and Booted into Recovery it worked perfectly.
I am still suffering lags on my device (more so than before) and this could be a product of my stupidity, or this rom being laggy. Either way it works, and I don't have to purchase a new phone!!!
Mod. edit: not dev related, moved to general
I experienced the same problem which can not boot recovery.
I've tried your way above but no luck.
Is there another way?

T-Mobile myTouch 3G - stuck on splash
Today I probably flashed my phone with a wrong (32A) SPL. I can't access fastboot, recovery mode or anything, including access from PC (either Linux or Window$). But it's stuck on splash - if it was totally bricked, would it still load a splash screen? Is there any hope?
Sigh.. I have the same problem.. Blue LED If I hold down the track ball but can't get to fastboot or recovery..
My problem started after I flash the HTC rom from the website.. Sigh.. I think it was the radio that did it..
Anyone found a way to get around this (w/o jtag)?
I am also experiencing the same problems. Blue LED works, cannot get into fastboot, bootloader, or recovery. It just sits on the opening splash screen.
Any other ideas?
Looks like I will just sell mine as a "bricked" device and hope to salvage a few bucks. Sigh
THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU. I would keep going but you get the point. I downloaded ROM Manager, and I flashed a Cyanogen Nightly ROM from 11-5-2010 and I got nothing but a Green spalsh screen and a reboot cycle. You instructions ROCK!!!
I went crazy and prayed a few times to unbrick my phone. I tried different things and then nothing worked. So I had the phone on for a bit and it restarted twice and then ran. Just let in sit for a while. Give it time. Maybe itll work for u too. goodluck

Can I ship you my bricked device so you can practice unbricking? I can pay you in random electronics

I think I bricked my device any help to confirm this would be really nice

I don't know what I did when I was trying to install the orginal rom but, now my phone just shows the mytouch 4g picture, then it goes black and the same picture appears again, while the phone is vibrating. I am able to get into hboot but none of the options work. I upgraded the firmware with clockwork and unrooted the device. Is there a way to unbrick, or is the device just a brick?
Any help I would be thankful toward,
Luke
This may seem trivial, but it was not mentioned and therefore I am asking. Can you get into recovery?
Sent from my HTC Glacier using XDA App
No I can't get into recovery its locks up and stays on t mobile mytouch 4g screen. That is after i select recovery.
Good news is its not bricked. You're just hitting a snag on boot. Have you tried fastboot or hboot?
RIP Cotton Eye Jim
When I try the fast boot method it brings up bootloader i selct it and it takes me back to the main screen, at that point I try recovery again and the device show t-mobile mytouch 4g for a second then goes black and goes back to the screen and vibrates and repeats the same thing over and over.

You don't choose bootloader in fastboot. All commands need to be run from your machine.
Sent from my HTC Glacier using XDA App
It does not even show the device in adb. I have install the driver for hboot usb plug, but maybe I got the wrong driver. Do you have a link to download that so I can try to reinstall driver, or is the unit bricked? Or how do I fastboot with the unit not loading to android, but its on hboot screen with usb cable attached. Is there a way to do that?
Press and hold the back button while booting to get into fastboot mode. Then download the clockworkmod recovery img and flash it through fastboot. You can find more detailed instructions in the thread where you download clockworkmod. This will enable you to enter recovery and flash a new rom.
When I followed those steps, fastboot in red came up and it gave me choice of bootloader reboot reboot bootloader and powerdown, it does not load, I have tried the bootloader, it goes to the main screen.
Was being dumb needed to hit restart it boots, thank you I will be reading on clockworks. I a noob as you can tell.
I reinstalled clockworks but now I cant get the hboot up by holding the volume down and power key. Any suggestions?
Volume down+power does nothing?
RIP Cotton Eye Jim
Got it working just wasnt holding it long enough I need to be more patience lol
Lol, I had the same problem the mt4g when I first got it. Very different from the mt3g. For future reference, as long as you get fastboot to come up, or at least get adb to recognize the phone, its not bricked. I actually bricked a mt3g 1.2, and when they're dead they're DEAD. Nothing works except an led notification.

[Q] Stuck trying to fix mytouch

Hello,
I have a mytouch that i have been trying to fix for the past 5 days now and have been to every corner of the internet trying to find an answer.
Background:
I rooted my phone and was running CM7 with no issues till it wasn't keeping my accounts and wouldn't let me add my accounts back on my phone. I decided to go back to stock and read that you were to just run the PD15IMG file. With previous rooting experience i went to clockwork and made a backup and also wiped my cache just to make sure. The update went smooth till restart when the phone was stuck on the splash screen.
Issue:
If i try to re install the PD15IMG file the phone will start to update but gets stuck on "BOOTLOADER - Updating". If i enter recovery i get to the green sync arrows with a phone for a few seconds and then the phone goes black and vibrates around 7 times. When in HBOOT USB the computer will recognize but ADB will not. In Fastboot USB, fastboot will find the device but when i try to erase or flash anything i get "FAILED <Remote: not allowed>"
My bootloader reads:
GLACIER PVT SHIP S-OFF
HBOOT-0.89.0005
MICROP-0429

Phone vibrating 7 times, if it's the same as for Nexus One, means - overheating CPU, which in turn means - dead phone that needs warranty replacement, if still available.
Sorry for bad news.
Wait give it some time in a.cool place because that's what I had to do got mine if that's the case

It'll only be a temporary solution. Unless you really heated your MT4G before getting those signs (having it under the car glass in black jacket, for example), there is no way that the CPU will reach overheating temperatures on its own. And when it does - it means bad stuff.
I can suggest (not joking!!) to try and turn on the phone while it's inside a freezer. If it turns on and functions properly there, but starts acting funny when outside - it's 100% overheating confirmation, and nothing can be done.

myTouch 4g won't start up.

I was updating the phone to OS 2.3.4 and while it was downloading I was browsing the internet and all of the sudden the phone froze, it didn't do anything for minutes, and then I took the battery out, when I put it back, the phone didn't want to load, it got stuck on the mytouch logo. I started to read and I did some steps to see if it work. I used the method pressing volumen down + power to go on HBOOT. I tried recovery first, then when it rebooted I got the red triangle with the exclamation mark. Then I turned it off and I tried factory reset, it took like 30 minutes or so and it didn't do anything. I was reading some threads here about some similar situations and I don't really want to do anything because they're instructions for different situations.

Nope, it's not giving me any error, just the red triangle with the exclamation mark. I "restored the stock" following the steps and it didn't work, but it didn't give me any error either. It won't just load, and now I can't even select the "factory reset" option. When I select the recovery option, an update icon with a phone appears, then it vibrates seven times and shut down.
I had the same problem. When the phone vibrates seven times, it's due to a hardware failure. If you still have a warranty on the phone, get it replaced ASAP

??Strange Android Issues??

So I have a Mytouch 4G and its stuck in Fastboot... Okay no problem. Flashed RUU Exe still wont turn on. Flashed RUU zip still won turn on. Unlocked Bootloader and flashed recovery and ROM still no go. Everytime I turnit on it goes straight to Fastboot. Only way to turn on is in fastboot wait 30 seconds and navigate to Hboot. In Hboot go to CWM in CWM reboot system now and everything works. I just have to do those 3 steps to turn it on. Has anyone else had this problem? And is there a fix?

it sounds like it is a recovery issue or a sticking volume button on the side..(just a guess) try pushing it up and down (wiggling it) if still an issue.Try flashing a different recovery such as 4EXT instead of CWM and see if that make a difference you can find it here http://www.4ext.net/ it is just something to try in case your recovery image is corrupted be careful ! let me know if it fixes your problem

It was actually stock and never rooted when I had this issue. The recovery was stock and still had the issue. It was when I installed CWM and a ROM that I was able to get it on, but I have to do those 3 steps.
Clean your USB port, check if any of the keys (trackpad?) is stuck. If you boot to fastboot and not to HBOOT - it means the VolDown key isn't the culprit, but maybe there is a key combination that is causing boot directly to fastboot, or maybe there' something in USB (dirt caused some high impedance connection between some lines) that causes your phone to boot to fastboot.

I thought that the Vol Down button might have been stuck as well but its not. All the buttons are fine and the usb port is clean.
