Smashed myTouch 4G. How I fix? - myTouch 4G Q&A, Help & Troubleshooting

after a slight impact with the floor, my phone is in a restart loop before the cyanogen boot screen. the only screen i see is the white "mytouch 4g" screen before it powers off and restarts. i can get into hboot, but the recovery option goes back into the restart loop. starting hboot gives some errors about being unable to locate these files:
PD151diag.zip
PD151diag.nbh
PD151img.zip
PD151img.nbh
i think i may have damaged the storage subsystem for sd + usb. last night i was getting a restart loop when i attached a usb cable to my pc, and i think these files are supposed to be saved on microsd.
any ideas?

Those files aren't located on your phone by default so your good, just download PD15IMG.zip from somewhere. I think it's in the development section. but download it, keep it named PD15IMG.zip and put it on the root of your SD card then boot into hboot it should recognize and ask if you want to update or not (vol up or vol down) choose yes and then wait for it to be done. make sure that you aren't low on battery because if this get's interrupted it will brick your phone. Once it's done just reboot and you should be good but this is the equivalent of a factory restore so you'll lose everything stored on the device (not the SD card)

i find it terribly difficult to read text that has no punctuation as well as all lower case because it is very difficult to follow you need to comprehend the damage that was done to your phone by water which may render it entirely unusable for a variety of reasons there are two flash devices in the phone the external sd card that came with it and an internal flash memory built in to the hardware which contains the android system the bulk of applications and your application data replacing your external sd card will not solve your problem if the internal flash memory has been damaged the red triangle is produced by the stock recovery program which can only recover if you have a recovery image loaded on your sd card here is something you can try download the pd15img file and rename it to PD15IMG.zip copy it to the root of an sd card to do so you will need to find another microsd device a phone or camera then insert the card into your mt4g phone insert the battery and hold the volume down while powering up you will be in the bootloader use volume up down to mouse between selections and the power button to select select bootloader select factory reset if this works and if there is no other damage your phone you should be good to go

You need to comprehend the damage that was done to your phone by water, which may render it entirely unusable for a variety of reasons.
There are two flash devices in the phone: the external SD card that came with it, and an internal flash memory built in to the hardware which contains the Android system: the bulk of applications and your application data. Replacing your external SD card will not solve your problem if the internal flash memory has been damaged.
The red triangle is produced by the stock recovery program, which can only recover if you have a recovery image loaded on your SD card.
Here is something you can try:
* Download the PD15IMG file and rename it to PD15IMG.zip.
* Copy it to the root of an SD card. To do so you will need to find another MicroSD capable device -- a phone, or camera.
* Then, insert the card into your MT4G phone.
* Insert the battery, and hold the volume down while powering up. You will be in the Bootloader. Use volume up down to "mouse" between selections, and the power button to select.
* Select BOOTLOADER
* Select FACTORY RESET
IF this works and IF there is no other damage your phone, you should be good to go.
same thing happened to me.had the exact same problem. i just let the phone completely dry out,for about a week then it jus started working.i did have to install the stock rom.
A few days later the phone just went blank again,so i sent it in to tmo and got a new 1 for free

[Q] Bricked!?!?!

I've heard about how it's pretty much impossible to brick the nook... Mine seems about as useful as a brick though. I was trying to set up a dual boot following these instructions. Basically, I had HC installed to the internal memory. backed it up, formatted system and data, then flashed update-nc-stock-1.2. CWM said that was successful. Then I rebooted with my CWM SD card out. Screen said "read forever" or whatever, then went blank. I waited for about 5 minutes, and pressed the power button. The screen went from an 'on' blank to an 'off' blank. Since then, I haven't been able to get it to turn on at all. Just an 'off' blank screen with no signs of life, even with charger cable connected. Tried it with CWM SD in and out. None of the buttons seem to do anything...
Thanks in advance!!
I'm pretty new to the Nook having just got it today, but I did some reading prior to attempting anything to see how easily I could back out if I had to.
Have you tried basically starting over (ie. Let go of the multi-boot dream for a bit and get back to basics)
You know, take a SD card, use diskimager to put the clockwork 3.0.2.8 image on it with the CM7 full ROM and boot to that, then format system, data and cache with clockwork and finally install the CM7 zip image (and gapps I guess) just to get going again.
If it all works, maybe take another run at whatever you are trying to do with the multi-boot stuff.
Thanks for the reply.
Sounds awesome; problem is I can't get the thing to do ANYTHING. boot period, into recovery or otherwise. I plug it in and it displays nothing - no 'wait 15 minutes and try again'. Just a black screen no matter what I do. I have an SD card with recovery on it, and i've tried making it do something with or without the SD card. No luck.
Good luck with your nook; I had really been enjoying mine.
So holding the power button for 10-15 seconds doesn't do anything?
Or when you plug in the power does it try to boot?
I mean in a complete worst case scenario you could grab yourself a T5 and open it up, disconnect the battery, and then reconnect it.
Then something is wrong with your Recovery SD card, as no matter what, hardware dictates that it reads the sd card first. The problem with what you did through dual boot methods is you resized partitions. So even if you do back out of all of this, you're going to be losing space unless you setup dual boot.
Recreate the CWM recovery card, either redownload the image and reburn it. Find a different one or something else, because it should load on startup.
Thanks for the help!
Reformatted SD again, then tried powering up with the power cord unplugged. Apparently it won't boot into recovery as long as the power cable is in, and whatever the boot was on EMMC was messed up. Happily running stock 1.2 now, next step, dual boot with HC!
Anyone know how I can delete this thread as it's pretty unnecessary?

OTA update broke my phone

So my friend has an EVO that was Rooted with Unrevoked. He sold it to his brother who did the OTA update like last week. Now the phone will power on and get stuck on the white screen that says "htc EVO 4G"
I have been working since 7:30 this morning trying to get it to work again. I have read pages of info on this problem but nothing seems to work for me. I Downloaded two different PC36IMG.zip files onto his SD card while it was in my EVO, then I had to move the PC36IMG.zip from the "downloads" file on the SD card to the main list of files using Astro.
I then put the SD card back into his phone and held the vol. down & power button to get in the hboot screen. The phone scans the SD card finds the file, does its little loading thing with the blue progress bar on the right...then it says "checking..." then it says
"Main version is Older
Update Fail!
Do you want to reboot device?
<vol up> Yes
<vol down> No"
I am at a loss
You did how much reading?
http://forum.xda-developers.com/showpost.php?p=15048543&postcount=1551
Check your bootloader. Is it s-on or s-off?
If it is s-off:
Get a pc36img of amon ra's recovery. Flash it like you have been trying to flash those other img's. When it is done and it asks about rebooting, say no. On the next screen, select recovery. Once in recovery, hook your phone up to your comp and enable usb. Put a Rom, such as CM7 or Mik's in the root of your card by drag and dropping from your computer. Close usb. Make a nandroid backup. Wipe everything, except sdcard. Don't format card right now! Flash the Rom you dropped on your SD. Reboot.
If it is s-on:
Find the official ruu. Run it. Learn patience, because it may be months before they find a root exploit.
This may help

Run the RUU and it may recover your Evo.
***THIS WILL REMOVE ROOT***
His phone says S-on.
I am trying the RUU now but at the HBOOT menu it never says HBOOT USB when its plugged in.

Dont use HBOOT USB use fastboot, Watch the video on the site i posted @ 2:28min it shows what to select in the bootloader
Im sorry, lol, thats what I meant. I push the power button when highlighting fastboot and it goes to the screen that says fast boot on top in red then says bootloader, reboot, reboot bootloader, power down....but it never changes to Fastboot USB.
Is your USB cable plugged in ?
or you have the wrong driver on your PC, there are 3 or so different drivers that can load mabe you need to change it to the one posted at the bottom of that page. or your phone is borked, if it is S-On take it to a sprint store and thay may be able to flash it for you.
Yes the USB is plugged in, i even tried 3 other USB ports. I downloaded that driver and after it was done I extracted the ZIP...but what now? In his video he didnt have to do anything.
I know it sounds a little too simple, but have you tried to clear storage from the bootloader?
I don't believe there is an official RUU of 4.22+ available yet, which leaves you kind of screwed. Since the bootloader is s-on, you cannot run any unofficial PC36IMGs through the bootloader. Since the update stuck you with the new bootloader, every RUU is going to give you that error.
Good news is that since you're s-on, you can take it to a Sprint store, tell them what happened (minus the root details, duh) and see what they can do.
Good luck!
i will give it back to him and tell him to try that. Thanks
Make sure you copy the files off the SD card and wipe the SD card before you take it to sprint!

MyTouch 4G/Panache bootloops? Freezes on loading screen? Recovery shows errors? Here

I guess the guide below is long overdue, so, here it is.
If your phone was or wasn't rooted, and one shiny or not so shiny morning or evening one of the following happened:
- It suddenly froze
- It suddenly rebooted by itself
And since then -
- it doesn't boot, but gets stuck in a bootloop or only shows the splash screen (stock splash is green "myTouch 4G" on white background).
- you're getting "can't mount /cache" errors when entering recovery (in case you're rooted)
In that case, keep reading this thread.
There are multiple reports of eMMC failures for a specific kind of eMMC on multiple devices. Please read this thread for more information.
There is a way to find out the eMMC type without rooting. Download Terminal Emulator from Market, install, run, type:
Code:
cat /sys/class/block/mmcblk0/device/name
Watch the result.
SEM04G - good.
M4G2DE - bad.
Both can fail, even without rooting. The "bad" has been shown to fail more.
All those steps are relevant when the device isn't failing yet.
When it fails:
If the device bootloops (boots through splash screen to bootanimation and then reboots, going in circles):
- Reboot to bootloader (remove the battery, insert the battery, press Power + VolDown simultaneously).
- Select "Factory reset".
- If getting to Clockworkmod recovery - select "Wipe data / Factory reset".
- Reboot.
In other cases, or if factory reset didn't help:
- Download the stock ROM in PD15IMG format:
http://www.filefactory.com/file/b4f....140e_26.03.02.26_M_release_155771_signed.zip
- Rename to PD15IMG.ZIP
- Put attention that you didn't rename it to PD15IMG.ZIP.ZIP! If Windows doesn't show you file extensions, like ".doc", ".exe" etc, then the file name should show PD15IMG only, without the ZIP.
- Copy the file to the root of the phone's SD card (do not put it in any folder).
- Reboot to bootloader (remove the battery, insert the battery, press Power + VolDown simultaneously).
- Answer "YES" when the phone will ask if you want to update.
- Wait approximately 10 min.
If the update passes cleanly - you'll be back to stock ROM and functional.
If the update shows "Fail-PU" - send your phone for warranty repair, because it won't function anymore.
how long does it take to update ?
mine gets ok on everything in hboot zip update but then "bypass" the 2 tp section....hmmm might be my diff .zip (it is a couple bytes off yours) currently waiting for download...Phone turns on to white mytouch screen, vibrates and turns off then back on continuesly
Yours just fails...curious gives me hope
Sent from my SPH-D700 using XDA App
Yours is just 211mb All others are 312mb...Yours seems to fail.. But unglitched my img crc menu...curious gives me hope
You have corrupt download. It's 312MB.
If it turns off and isn't stuck on the "MyTouch" screen - your problem is different.

my says main version is older!
update fail!
is there any chance of the phone being resurected
Find a newer RUU - the 2.3.4 version in RUU format, and I believe the link in my post is 2.2.1.
i followed the steps and the phone says "update complete... press power to reboot" but when I do the phone still bootloops. what could be the problem?
Could be HW problem of some kind, not eMMC-related.
Hi,
The problem I have is it only shows the splash screen (stock splash is green "myTouch 4G" on white background) when
starting the phone.
Before this happened I had rooted the phone and updated the ROM and was putting some patches on the phone, Recovery shows
info as s-off.
To do a recovery downloaded the stock ROM from your link
(PD15IMG_Glacier_TMOUS_1.17.531.2_Radio_12.28b.60.140e_26.03.02.26_M_release_155771_signed.zip I also did a hash check
and it downloaded fine no corruption) renamed image with the exact name PD15IMG.ZIP (made sure it was not a
PD15IMG.ZIP.zip) and copied it into an empty 1 gig SD memory.
I re booted, did a factory reset x 2 after going to boot-loader, that did not help so I inserted the SD card with only
the PD15IMG.ZIP image in it and rebooted to recovery, but recovery does not ask me anything when it looks for the
PD15IMG.ZIP it says no image or wrong image (it also looks for PD15DIAG.ZIP, PD15IMG.nbh, and PD15IMG.zip same
message) and puts me back into recovery.
Any Ideas on what I should do ?????
Thanks
you're suppose to flash PD15IMG.zip in the bootloader/hboot not the recovery.

I know this is a bit of an old thread, but did you ever get that newer version of the .zip file? The 2.3.4 version discussed above? Or anyone know how to find it?
My phone says the same thing. Thanks
2.3.4 updated Stock Rom
I'm up and running again !! I found a PD15IMG.zip file on the t-mobile support website that worked specifically for the latest 2.32.531.1 update !! After downloading it, renaming it to PD15IMG.zip, copying it to the MicroSD card and booting into HBOOT, it found the file, loaded and checked it and asked me if I wanted to update. Everything is working since. Here is the download link (I've uploaded it to megaupload): http://www.megaupload.com/?d=X1EAIPBJ
I hope this helps !!
This is what happened: I bought two MyTouch 4G's on craigslist from the same seller (a couple) and his phone works fine, only hers was corky, it wouldn't go past the MyTouch 4G screen. Both HBOOT screens are identical too, I checked his software version and it is the latest one (2.32.531.1), so I assume that hers is the same, it also shows the same date, July 15 2011 and the same radio 26.13.04.19_M in HBOOT. After trying both different PD15IMG.zip files (2.3.4 and 2.2.1), I've been getting the "main version is older" errors on both. No Fail-PU though, so that made me hopeful that there was a solution. I'm thinking that she updated to the latest version and somehow it got corrupted, that is why the phone was stuck at the MyTouch 4G loading screen and wouldn't go any further.
My phone wouldn't turn on this morning so I found posts suggesting to download one of the PD15IMG.zip files. I keep trying to update my phone but it freezes after I select yes to update. Does anyone have any suggestions? I've run out of ideas.

My phone is unrooted. I tried a different sdcard earlier, I'm starting to think my phone is just done for. I just want to be sure before I have to give in and buy a new one
i downloaded
PD15IMG​_Glacier​_Gingerbread​_S_TMOUS​_2.19​.531​.1
renamed, went thru the whole install process and instructed me to power down to begin using the phone
keeps doing the same thing... stuck on the My circle logo, then powers down. either that, or does the factory reset, powers down, and goes back to it again once powered up.
suggestions?
Reflash again.
If the same problem occurs, and the reflash completes ok (no "Fail-PU" message on any partition) - then you most likely have some non-eMMC-related HW problem.
My phone was performing the update and turned off for some reason now wont turn on at all, not to boot screen or hboot screen.... what now? it shows the charging light but thats the only sign of life
---------- Post added at 11:26 PM ---------- Previous post was at 11:21 PM ----------
i got it to start the update next thing i know i look over and the phone is off and wont power on at all, wont go to boot screen, wont go to hboot nothing, the little flashing battery light is the only sign of life... any ideas on how to fix this?

Bricked Evo... stuck at bootscreen, wont boot into recovery

I just partitioned my SD card and flashed a new rom (RunnyBliss HybriD) tonight. Everything was working fine, I just reinstalled all of my apps and everything was perfect. I went to unplug my phone from the computer (which was on charge only) and just unplugged it. After that, all of the apps I downloaded were gone and the home screen pages that I just setup were gone. I decided to reboot and see what happens and to my surprise it wouldnt boot back up. It is stuck at the white "htc evo 4g" screen. I tried to boot into recovery and it vibrates 3 times and then does nothing. I assume that the phone was actually in USB mode and I corrupted the usb by removing it without ejecting it. Long story short, I have an Evo that doesn't work and I dont know what to do. My computer wont recognize it so I cant access the SD card. Please help.
Correction: If I press volume down I can get into hboot. What do I do from here?
try to install a recovery via the bootloader
How would I do this?

I'm kind of new to this but, in HBOOT there should be a recovery option, select that and recover the latest backup.
EDIT: If Recovery doesn't load then I'm at a lose, sorry.
I figured it out. I got a new micro usb and placed AmonRA on it and then booted into recovery, then went to usb mode and dropped a new rom on it and flashed. Big bam all fixed
