My mytouch 4g that i just rooted is stuck at the mytouch 4g screen. I downloaded a custom rom and since then its stuck at the mytouch 4g screen! when i go to the recovery it says cant load cache and missing things so something is wrong i really need help this is my only phone!! please anyone
did you try restoring your stock rom from from your nandroid backup?
i had a problem similar to that and i think it was because when i made my backup i didn't have enough space on my sd card so it just got stuck on the boot screen. i just flashed the PD15IMG in the bootloader and it completely restored my phone back to stock.

He's getting cache errors which usually points to a failed eMMC chip which he should've checked before rooting. A improperly made backup will not give out cache errors it will either error out or just bootloop your phone till you wipe and reflash a ROM. So if you can get ADB to recognize your phone and can check your eMMC chip it will most likely be the bad one.
Sorry for your bad experience with the phone just send in for a warranty replacement recheck the eMMC on the replacement. If its good go crazy but be careful in what you flash

Jst bcuz u have the bad eMMC don't mean anything. I have the bad one and I've flashed every sense rom, the liquid rom, miui.us, and demonspeed miui. And I haven't had any problems and I've even rooted and s-off and then put s-on and unrooted, and then rooted and s-off again jst to see if becuz I had the bad emmc it would bootloop or die, and nothing... works perfectly fine. So back to the question, since you can't get into recovery go grab the PD15IMG.zip and place it on root of phone, boot into bootloader, and when it asked for update say yes. Let it do its thing. Then reboot, and bam phone should work again. Then jst reroot and use rom manager to flash recovery and there you go.

You've been lucky so far. Just because your eMMC has not yet died, doesn't mean that it won't. If the OP's eMMC has failed, flashing PD15IMG.zip is not guaranteed to work either. Most people get the dreaded Fail-PU error message when flashing it, which means the phone is truly bricked. It's worth a shot though.
Oh, and I hit 'thanks' by accident, so you get your first one for free.

Yes, I'm afraid it is. I was just trying to give a more realistic account of what eMMC failure is like.
I love the smell of fried eMMC chips in the morning.

I did hours of research to figure out my error I'm getting on the phone, I can't find a way get this fix..When I boot up the phone to HBOOT it's trying to do a sd checking and try's to find PD15IMG.zip it doesn't find it. I launch Recovery, Once It loading up CWM v5.0.2.0. I get this errors
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
So this isn't good, I even know that. So what i did wipe data and cache it does it fine and works. So when I try to restore it wont let me at all, so that mean it corrupt, so im stuck now. Did my research on here, some say to flash a new rom, well i did and didnt work at all, it came to a point that it wouldn't let me installed a rom also. I just need help with this, I really need to use my phone. I had to installed the a rom doing a ADB way, it work but it still won't boot up at all. Can anyone help me with this?
Do you have a bad eMMC? Have you checked it?
At this time, the first priority is to boot up the phone. so return back to the stock Rom.
Just follow this steps for an error free installation.
1. Download the stock 2.2.1 rom here.
2. Rename it to PD15IMG.zip
2. Place it on the root of your sd card.
3. Remove the battery and Switch On your phone while holding the Power button & the down volume button.
4. The hboot menu will update your phone (do according to the hboot instructions).
Once you are in the stock Rom, check the eMMC. If it is good, you can proceed with rooting.

IF THE BOOTLOADER SHOWS FAIL-PU THEN YOU ARE BRICKED. Fail-PU means failed partition update, nothing could be written to the eMMC chip, since the chip has died.

I haven't check if the eMMC is bad or know how too, but I'll do a search to see how. I'm not getting a fail-PU at all. I can't get hboot to read the PD15IMG.zip file to update and get this to stock. It just saying no img. Is there a other way of doing this?

Is there a way to do it by adb? I know my sd card isn't bad cause it read fine on my laptop. Also if i did the gfree way, would I have to remove it?
I got a fail-pu, for some reason my sd port isn't reading. As I can see there no way on fixing this error. So my best bit would be replaced the motherboard. thank you guy for the help..

Fail-PU means failed partition update, which means the eMMC chip died, which basically, to sum it all up means you're bricked.

Need tons of help! I've been searching the forums for almost 24 hours now trying everything and still can't get it fixed. I rooted and got s-off on my wife's MyTouch 4g. I installed ROM Manager and flashed the latest CWMR 5.0.2.0. I did a full Nandroid backup. Then I tried flashing a Gingerbread ROM over the Froyo rom. It went to white MyTouch screen and never left it. I finally gave up and went back to recovery. When I try to restore using Nandroid, I get this:
Error while formatting /system!
E:Can't open /cache/recovery/log
E:Can't open /cache/recover/last_log
I can get into HBOOT, Fastboot and Recovery just fine.
I tried the RUU exe floating around and it always fails trying to reboot bootloader.
I tried letting it autoupdate the stock PD15IMG.zip floating around it always fails.
I've tried flashing different recoveries including older CWMRs and always get error about remote not enabled.
I'm at my wit's end. I'm leaving town tomorrow and need to at least get back to the nandroid backup before I leave. Any advice?
Wrong section dude ! Read the forum rules .

I put PD15IMG.zip on the sdcard. HBOOT checks the file and prompts me to update. When I choose yes, each option shows Fail-PU.

I had the same problem, bad chip, just keep the ROM you are currently running, if you try to flash some thing you will have a semi brick.I couldn't never solve that problem.

not necessarily.. i recovered one of my MT4G's thats had this issue... Engineering bootloader is what saved my ass...OP, Did you flash the Eng bootloader when rooting your device??
That's the problem. I wasn't able to successfully flash a ROM so it's useless.

Greetings
My phone is failing to boot after a failed restore. The phone is rooted and has S-OFF. After flashing a custom ROM I wiped and tried to restore a backup of the stock rooted ROM. That failed while writing the partition cache with an error like this: E:Can't mount /sdcard. During the restore I connected the USB cable right before that error appeared and I suspect that was the cause. I rebooted the phone from recovery, the boot screen came up, sat there for a while and then it entered a boot loop. I pulled the battery at that point. Afterward the phone wouldn't boot into fastboot or recovery. The LED doesn't come on when I plug in USB but the PC detects QHSUSB_DLOAD as new hardware. Is there anything I can try to fix this?
Thanks,
Boz
So you can't boot into the bootloader or recovery at all?
Sent from my HTC Glacier using XDA App
Nope, I can't boot into the bootloader or into recovery. The phone is pretty much unresponsive except for the QHSUSB_DLOAD device detected by the PC.
Wow. Sounds toasted to me. Sorry. Just play around with it using different ways of powering it up.....like without the SD card, hold the buttons then put it the battery, and other ways like that. If it still won't do anything, it seems like your bricked.
Sent from my HTC Glacier using XDA App
Yeah, that's kinda what I figured. I'll play with it some more but I ain't holding my breath. Can tmobile/htc fix this? If so, how much would it cost? I've had the phone for about 10 months but I don't have warranty on it.
You could take it to a T-Mobile store and ask them. They might give you a replacement if your lucky....or maybe a discount for a new phone. Don't mention that it was rooted or that you tried to fix it though. Just tell them it stopped working.

That's what I'll be trying after work today. Hopefully they won't give me too much crap.
Read my "if you think you're bricked" guide...
Its a sticky in the general section.

ask and answer these two questions to yourself:
1) can you enter bootloader?
2) can you enter recovery?
Note: if you can't enter either one of those, and your device doesn't show any signs of life, then don't bother reading on, you are truly bricked.

I installed the HORSEMAGEDDON ROM and it worked - for the most part. But it kept giving me annoying errors about different apps that were attempting to update every time I turned it on. So I tried to restore my backup that I had made with CWM 6.0.2.8. However the backup apparently did not restore properly because it now boot loops back into CWM any time I try to start it. I get the errors:
E:Can't open cache/recovery/log
E:Can't open cache/recovery/log
E:Can't open cache/recovery/last_log
E:Can't open cache/recovery/last_log
So I tried to reflash HORSEMAGEDDON but it still loops back into the CWM recovery screen.
I have wiped everything according to the instructions on the HORSEMAGEDDON thread.
HELP!! This happened to me on another U8800-51 phone and I wound up hard bricking it trying to get back to stock.
Anybody???
Does anybody have any ideas on how I can fix this?

Yes. I did a wipe of data and factory reset as well.
What I would do is get an SD card with a custom rom on it and try installing it from recovery menu

Obviously you have been having problems with that rom, so go with something different.

Okay. Here is what I did step by step:
1. I was on Stock 2.2.2 Froyo and flashed HORSEMAGEDDON successfully. But I had some errors related to updates since it was such an old ROM the updates were all for much newer versions of the apps tied to 4.x.x.
2. I attempted to restore my backup made with CWM 6 to return to the stock. It said it completed successfully but when I rebooted it just looped into the recovery screen with the error messages posted in my first post.
3. So I tried to reflash HORSEMAGEDDON and it said it completed successfully. But it still bootloops into recovery.
4. I can access most of the features of the recovery. I can access the pink screen and swap recovery versions. I can access my SD card from my PC when I mount it from recovery.
5. Yes, I did do full wipes with each attempt to reflash.
The ROM was not the problem. It worked and worked well other than update issues for apps. It was only after attempting to restore to stock I ran into issues.
The problem appears to be something was corrupted when I tried to restore my backup, even though it said it completed successfully.
So if I try to flash yet another custom ROM, even if I could find one I trust given all of the version issues etc., I don't think it would act any differently. But if somebody can recommend one I am all ears. Keep in mind I have a -51 phone so it will have to be for that or the PRO.
Given that, how can I get back to stock? Am I the only person who has ever had this problem? I don't believe that is the case, so somebody must know how to fix it or can point me to a procedure to repair the internal memory.
Help!!

None of the fixes on this link seem to apply to my situation.
When I said "bootloop" I may have misused the term. What happens is I power up, it goes to logo screen for about 10 seconds, shuts down and restarts to logo screen then goes into recovery after about 5 seconds. From other info that I have found it is due to a corrupt bootloader and I need to reflash the bootloader. Problem is, reflashing the bootloader i.e. CWM, does no good at all.
I am also hampered by lack of info specific to the -51 model. And I cannot find a copy of the stock ROM anywhere that is for the -51.
So essentially I am screwed. All of that said, I have found a new phone for $40.00 so all is not lost. It's a U8800 but not the -51 or PRO. I don't plan on customizing it, I'll just stick with stock. After trashing two phones even after following the advice to "BACKUP" I think enough is enough. Backing up did me no good whatsoever in both cases.
In my estimation, the culprit is CWM, or at least the versions I used.
If anybody has any advice I'm all ears.
