Mytouch 4g Stuck in Bootloop - myTouch 4G Q&A, Help & Troubleshooting

This is my friend's phone she told me to try and fix it for her. It's 100% stock 2.3.4. Stuck in a boot loop. I can get into hboot but if I press anything it just freezes like factory reset. I also tried flashing pd15img.zip and it starts but then gets stuck at flashing bootloader and doesn't go past that...any ideas? Is there an RUU I can use through fastboot like other HTC phones?

No RUU's. According to my understanding, if the device repeatedly freezes on updates and refuses to install them correctly, your device is toast. Anyone care to verify?

Confirming estallings15's answer above. The device is dead, most likely corrupted bootloader.

Experiment
If the phone is truly unsalvageable experiment with the ADB you might find something interesting.

Have the same problem on my gf's glacier. Powered it down, borrowed the sum card for a sec, replaced it and turned it back on. Got stuck at boot loop and the other problems in the 1st post. Can't we check if its corrupted with image crc?

Unable to flash with RUU

I did all the steps to root the phone, 1 and 2, but got stuck in a bootloop. The sprint log stuff would come up, the the 4g, then back to sprint etc. I flashed the PC36IMG.zip of the shipped version, but now I can't get the RUU to take the phone into a fully factory state. It starts, then gets stuck waiting for bootloader with a black screen and htc on it. I really just want to make it factory again and start over with the root process. Any ideas?
Hold power and volume when turning on phone, then select fastboot and have the selection for bootloader highlighted, then start the RUU it should work then.
OK, so I tried the volume down + power btn deal, but still no dice. I really don't undestand wtf happened, cause before doing the 2nd part of root, I was able to load Damage ROM, now anything I load besides the PC36IMG.zip from part 1 just bootloops. Crazy

ive seen this answered in the RUU threads. they mentioned the RUU doesn't automatically reboot the phone into the correct mode, i think it was bootloader? manually booting it into the correct mode, then connecting the USB, resolved the issue.
you might want to search/reference the RUU threads for more details as i never had the issue and am only recalling off the top of my head what ive read, which cant be 100% accurate!
When RUU stops/freezes and your phone has the black screen with "HTC" on it.... do not restart your phone or anything leave it the way it is. What you do is exit out of the RUU program by clicking "exit" when it freezes up. Then without doing anything to the phone, just restart the RUU program and it should pick up where it left off and complete the process. I found this fix in "Q and A" part of the Evo forum and it worked for me.

You need to format the phone rest and format cashe then install the rooted image and it will boot. I had the same problem.
Thanks for the responses, it is working again, YEAH!

Is my HTC Magic totally bricked?

I bought a Rogers HTC Magic for a pretty cheap price. It had The Rogers 1.5 Sense UI update on it. I decided I wanted to root it and load other ROMs, etc. So I read that the easiest method was to use Universal Androot to root it, and ROM Manager (from the Market) to flash the appropriate recovery image.
So, I installed both apps. I first ran Universal Androot and rooted. I confirmed root through ADB and also Super User permissions. I then restarted the phone just for peace of mind. After the restart, I ran ROM Manager. It automatically popped up and asked me if I was running an Ion/My Touch or an HTC Magic. I selected HTC Magic, because that's what this is. So then it flashed the recovery image and restarted the phone. When it restarted it went to the Rogers boot screen for a few seconds, and then started a loop of restarts. That's all it does now. It shows the Rogers screen for a few seconds, goes black and reboots over and over. I have tried booting into HBOOT, Fastboot, and into recovery. I cannot boot into any of them. One thing I did notice is that when I'm pressing any of the combinations (volume down + power, home + power, menu + power) for a very brief half a second right before the phone restarts, the bottom of the screen says "ClockwordMod ..." where ... is the version of the image (I'm at work without the phone, so I don't recall the exact number there).
So, is this thing officially a paperweight now, or is there some sort of hope?
Thanks.

Well, I don't know if you are full-bricked but here is what went wrong. The HTC Magic recovery is incorrect for the mytouch3g (at least the 32b). There was a top option for "saphire/mytouch 3g" which is what you should have chosen. So, you can't load the incompatible recovery. Can't you boot back into the rom you were using? The recovery flash shouldn't have messed with it. If you can, boot back in and flash the correct mytouch3g recovery in rom manager.

Okay. That's weird. I mean, my phone is a Magic so choosing the option for the Magic instead of the Ion/MyTouch seemed to make sense.
Anyway, I cannot get anywhere. Holding vol+ and power does nothing, neither does home and power or back and power. Are there any other tricks to getting anywhere beyond this endless restart loop?
Thanks.
Starting to think I'm screwed.

You may be, I'm not sure exactly what state you are in but the recovery you installed was for a magic 32a (that you have) with a 3.x radio (that you don't have)
The rogers sense rom uses the 6.x hero radio and needs a hero recovery.
The mt3g uses a 2.x radio thus yet another recovery.
Try booting with volume down to see if you can get into the hboot/fastboot screen, but I think you tried this already.. you may also try letting it loop unplugged until the battery drains it may error out giving you access again..
Besides that there is the option of jtag and fixing the software stack that way.

Right, I cannot get into fastboot or hboot. I'll try running the battery down when I get home today. Interesting idea.
Unfortunately running the battery dead with restarts didn't do the trick.
Any idea if there's any place I can send it to who has the smarts to jtag recover this thing?
Thanks.
me too
I did the same thing on a 32B. Rooted. loaded ROM Manager. Ran the recovery, I choose the Ion/MT3G option. tried to load CM6-FroyoRedux-v1.7-32b-blk.zip. Now it's stuck in the boot screen.

I don't think it's the same thing.
I rooted, loaded ROM Manager and installed the recovery. I was never even able to get into recovery in order to try to load any ROMs.
I have a Rogers magic, and its a 32a. One way to fix it is to go to the HTC website and punch in your serial number and download the rogers update. Only problem is that will make it a pain to root again. But should fix that reboot loop. But do that as a last resort to get the phone running again.

The phone does not identify itself to the computer, so this doesn't work.
The program should try to put the phone into fastboot mode, and install the upgrade. Have you tried pulling the battery and pressing the power button + back, once the battery is installed again?

Oh yes. I've gone crazy trying every key combination with every combination of taking battery out, plugging it in, USB cable attached, detached, etc.
The phone never identifies itself as a piece of hardware to the computer in the 5 seconds between reboots.
I had the same problem yesterday, and i was doing the same rooting with Universal Androot and flashing recovery witch Rom Manager (choose the same options). I tried to go into recovery and then it started to bootlooping the whole time.
I was pretty scared when that happens, can't open fastboot menu and the only thing that my phone was showing was HTC logo and a quick blink of clockwork sign over and over.
I don't know exactly how i managed to fix it, but it started to work when i quickly plug off baterry and i immiediatly plug it in (I was doing it at the exactly time when the phone reboots) while holding the power button.
Now my magic turns on, but recovery won't work (just flash for a moment, and reboots) and it always say at the beginning of booting system that SD card was removed which means i can't use any SD card.
I hope it somehow helped you.

I tried doing this quickly for about 5 minutes this morning but didn't get it to go anyway. I can try some more after work today.
When you say it booted after this battery pull thing, do you mean the phone booted right into Android, or you were able to get to hboot or fastboot?
Thanks.

I wasn't able to get hboot or fastboot. I pluged off and on the battery in the exact moment when the Logo came out after restarting. The logo was on the screen for the whole time, even while battery plugged off. I guess, i've done it so quickly that phone didn't switched off.
I think i was holding the power+home or power+back buttons all the time.
Can't really rember the exact way, sorry.

Try removing the SD card and booting if its not restarting due to the wrong radio too soon that may help.. if you get into android restore the SD card and run the exploid process I posted a bit back for rogers magics, or the older goldcard method.
I've played around with taking the battery out and putting it right back in at all different times during the booting and can't get the phone to behave any differently. Iv'e tried it with SD card in and SD card out, USB cable in and USB cable out. I can't get anywhere.
I did notice that the phone does show up as an Android device for a second when it's booting. Tried to catch it in adb but no luck.
Starting to think this thing is shot. Any other ideas?
Just so everyone can see what's happening, I recorded a video and uploaded it. Linked below:

try to hold and KEEP holding the back + power... Not volume down!
Don't push and release like you did in the video.

[Q] Nexus one modem seems busted, bricked?

Hi all,
I've bought a Nexus One from a friend that went to US a while ago (I live in Brazil). My N1 was exhibiting an overheating & reboot issue whenever I used the 3g connection.
2 weeks ago, just after a phone call, it rebooted and did not come back. I took the battery out for the night, but still did not come back.
The bootloader is unlocked, but I was using stock gingerbread. I can get into fastboot, but not recovery. I tried the PASSIMG method a couple of times, and tough the flashing did succeed, the phone keeps stuck at the X logo.
The last radio flash was 5.08, when ginger came. Does this means my device is bricked? To make matters worse, it seems I'm out of warranty...any of you guys have any clue to help me? Or is it all lost and I should get a new phone??
Thanks!
If you're booting - you're not bricked. Brick = NOTHING on the phone, no reaction whatsoever to anything, won't turn on.
Anyway, since you have your bootloader unlocked - fastboot flash recovery recovery.img, and then try to boot into recovery, see if it works. Read the Wiki to help yourself.
Hi Jack, thx for the reply!
I already tried that; the flash succeeds, but I cannot get into recovery. If I try to reboot into recovery, it still gets stuck at the X logo.
I understand that brick == nothing at all; but I suspecting that the GSM modem is history. I was already having rebooting problems with it, and now it seems that it's dead and the phone will not boot because of it. Does this makes sense?
Have you tried "fastboot boot recovery.img"?

Just tried it, the phone reboots, but vibrates 7 times and does not boot, still in the X logo...
7 vibrations - means you have some HW problem, and the phone won't boot. Yes, I guess that even though you're not bricked, the phone isn't usable and needs to be fixed/replaced. Sorry.
That was what I was afraid....I had this "7 vibration" stuff happen before, but I was able to get it back on track...
Thx all for the help, time to get a new gadget

mytouch s-off in bootloader nothing else works..bricked?? fixable??

I had freezing issues, my mytouch 4g would just end a call and id have to take out the battery and restart it or it would freeze on a screen, even the start screen ans wouldnt do anything and id have to take out the battery and restart it. I tried deleting apps to make it stop doing this but nothing was working. I talked on my phone the other night and as soon as i hung up it froze, i tried restarting it and now all it will do is go to the mytouch 4g boot screen, but it wont boot up. usually it would flash that screen and go to the sceen with the green dot the wrote my in the center then reboot, but it wont go past the mytouch 4g screen.
I have tried holding the volume down button and set back to factory settinfs, but all that did was sit on the skateboarding androids screen until the battey died, I have tried this many times both with and without my sim and SD cards in.
I have tried recovery and my phone acts like its going to restart then flashes and phone with a red triangle and exclamation point on it and wont do anything, wont even come back on until i take the battery out and put it back in and turn it on again.
things to note: i am able to get into the bootloader screen via power and volume down but anything after that such as factory reset and recovery fails, i rooted the phone and it is S-off. I wont mind sending it back to tmobile but i need to get s-off in order to do so. I would do adb but i am unable to get into recovery so i cant. i also would flash the pd15img.zip but the phone while in hboot i keep getting failed pu on everything then nothing happens.
any help on possible solutions would be greatly appreciated. I dont even really need it working i just need s-off so even if it wont work i can send it back to tmobile. thanks in advance
if you are getting the 'fail pu' message your phone may be bricked. unfortunately there are a lot of other people that have experienced this. I'd send it back to t-mo anyway, they are aware that this problem exists.

Ok so I wont be charged anything by the insurance company although I rooted it last year. I don't want to send it in and then get a a crazy bill for
like $400 because they receive the phone and find out that it was rooted.
Hi, did you try and go to T-Mobile site and select your phone and download the OTA through their program in the support section. It will restore it. Then redo the downgrade if u don't have s-off

Stock phone, unable to boot under any mode

Hi all,
I have a stock mytouch 4g and yesterday it froze during an update. After rebooting it a few times to no avail, I did a factory reset and still got nothing, it just kept getting stuck on the beginning image.
I factory reset it without the SD card, and it booted (showed me the introductory video) but then as it was asking me to set-up my e-mail accnt it froze again, and that was pretty much it. I reset it every which way after that and got nothing but it getting stuck on the first image.
I also can't go into recovery mode, nor fastboot. On recovery mode, it shows me the alert red triangle sign with an exclamation point.
Please help?? (I refuse to believe my phone crapped out bc of an update! =[ )
Thank you kindly,
Nasja
You need to find the stock rom and place it on the root of your SD card and then boot into hboot and it should ask you if u want to install update then just wait for it to install and your phone should work fine again

You'll probably need one of these. I'm guessing a gingerbread version.

PC not seeing the phone
Hey, thanks much for the reply, but I plugged my phone to my PC, but it doesn't see it (or read it rather, it pops up as removable disk but if I click it, it tells me I have to insert a disk ).

I had the same type of thing happen to a phone I'm looking at for a friend.
He lent it to me because it wouldn't boot past the mytouch logo. It would boot into boot loader, but wouldn't allow us to select wipe data / factory reset. I tried to apply the update through the Bootloader like preciously mentioned, but it kept hanging and wouldn't load after 10 minutes or more.
I've noticed it's extremely delayed when it even runs the scan in Bootloader for new recovery and other updates. It probably takes about 45 seconds to do the scan.
Anybody have an idea what's causing this? I read in another thread that it may have been caused due to the phone overheating.
