Bricked Your HTC Desire Z/G2?

--- If you have bricked your HTC Desire Z or G2. I have a method that is sure to work! In the past I bricked the same device and I have found a way around it. Follow these steps and post and thank if it has worked for you! ---
How To Unbrick A HTC Desire Z or G2!​
Step 1: If your device is rooted and flashed with "ClockworkMod Recovery" and "S-Off"you want to start by holding down the Volume Down Button and holding the Power Button for about 7 seconds.
Step 2: You will suddenly be welcomed with the HBOOT Menu. Scroll down and select Recovery.
Step 3A: You will then be showed the "ClockworkMod Recovery" Menu. (Read the message below!)
Step 3B: First you will need to Factory Reset and Clear Cache Partition!
**If you have a backup or restore point continue to Step 4A if not you will need to install an alternate ROM and proceed to Step 5 or Factory Reset which will only reset for that ROM. For another possible solution a read end of post!**
Step 4A: Now from here you will of course scroll down to Backup and Restore, select restore and select your point of restore!
Step 5: Now if you have another ROM located on the SD Card of your phone you can scroll down to install zip from sdcard and find the zip file (gapps if required) and install all of the following and reboot!
Step 6: Enjoy your UnBricked device!
---Alternate Solutions---​-- Fix Permissions and reboot.
-- Factory Reset and Reboot

... lol I had to do this method long ago. Bad thing is I had to find out on my own but is good that you posted this. I think it will help out.

Am not really sure... I've never had this issue before. Well do you know how to use ADB? If you do can't you flash clockwork again maybe that could fix the problem. I really don't know how to use ADB since I used Unforgivens way of s-off.

yeah ive been getting help from someone from the cyanogenmod forums and we have tried many things flashing recoveries and all that but it keeps giving me errors.
I dont think that i can reflash clockworkmod because i dont have eng s-off just ship s-off

Thanks, very helpful!

If your phone is bricked then you won't be able to get into hboot at all. So it would be helpful if you would consider changing the title etc of your posting. This won't help a phone which really is bricked.

This method has worked for me in the past and there is a possibility this can work! So "Steviewevie" I wouldn't post a method I haven't tested in the past! I have Unbricked 2 devices with this same method. There is ways around everything. So "dragokld" keep trying and try the method "lainvalenajr" has given. I will check for more methods and experimenting. Sorry for the inconvenience.

I have tried this method, but I cannot reach the CWM menu, all I can do is try the standard HBoot recovery from PC10IMG.zip, but it dies at RADIO_V2 step after many Fail-PU on all other steps: what can I do?
My DZ was rooted, flashed with CWM and Virtuous ROM. I have a nandroid backup on the SD. It died today with "can't mount" error messages after a freeze and reboot.
Also tried Factory Reset from HBoot, but it hanged at the "androids on skate" screen forever..

These instructions are just "how to flash a ROM" or at best, what to do after a failed flash.
I don't want to sound like a jerk, I think it's great whenever someone takes the time to help others, but these instructions will not work for a bricked phone.

Allright, I'll keep following the other thread then.

~I think my device have a hard brick
SIGN-ON
normal HBOOT 0.82.0000
Rooted
Clockrecovery installed
radio: 26.02.01.15_m2
I can't pass the boot
I can't any radio
I can't downgrade radio version
I can't use misc.img

After I select recover the phone just froze at HTC white screen. Clockwork recovery was installed and flashed.

I think this is called "soft-bricked"
hard-bricked is when none of this stuff is possible and you have to send your phone and $40 to that famous dude here in the forum who un-bricks anything.

Hi, I have an unrooted Desire Z on Bell. I recently experienced a hard lock and upon battery pull, discovered that my phone would not boot up (frozen at the htc screen). I can hold volume - and the power button to get into the boot menu, but can't seem to perform a factory reset or enter recovery mode. Recovery brings me to the screen it should initially (with the green circle/arrow symbol) and then the screen goes blank and the phone vibrates a total of seven times before...nothing happens. Selecting factory reset just hangs up the Hboot menu.
All I can really do is go into Fastboot or IMAGE CRC, but don't see any options there. Any one have any ideas?

Before this, i also experience half brick. My DZ already s off. So i just flash the stock rom & gain the root again. Flash the custom rom & my DZ back to normal until now.

I was using CM7 for about a month, without any reboots at all. Recently i got greedy and wanted to try out MIUI, so i downloaded the latest ROM and copied it onto the SD card and ofcourse flashed the system with it. After rebooting i only get to see the lockscreen and after that the phone just reboots. I have tried everything there is, but with no luck.
It seems i can not revert the phone back to stock reco, rom etc. either, because first i need a working system to do that.
Any ideas, people?
Thank You in advance,
a worried Android fan from Estonia.

Bad recovery?

Question I bought a mytouch 4g and it was stuck on the boot screen and so I checked to see if it had recovery and I went into boot loader and it has s off and when I try to load recovery I get this message
E:Can't open /cache/recovery/log
E:Can't open /cache/recovery/last_log
If some one could point me in the right direction it would be greatly appreciated.

Did you buy it that way?

Yeah i bought it that way it was in mint ondition for $80 thought i might be able to fix it. Can i just restore factory rom through bootloader? Im still a newb at this.

The recovery i mentioned is Clockworkmod 3.0.2.4

I'd get your money back if you could. It sounds like this jerk knowingly sold you a bricked phone. When you get those cache errors in recovery, it's essentially bricked. Try searching for restoring by flashing PD15IMG.zip through the boatloader. It's basically unrooting and flashing the stock image, but it does not always work.

What tj said. One way you can try is flashing a clockworkmod 2.x.x recovery from fastboot and fixing the catches. However, if the recovery partition is too far gone you will truly brick the phone. If you can't get your money back try his way then try my way. If neither work you got jacked for $80 sorry bud.

Well i tried to flash PD15IMG.zip and it came back with failed PU. Im going to try and flash a 2.x.x.x. recovery image see if that works.

Update your findings, I'd be interested to know if it worked

Well I tried to set up SDK to use ADB to push the CWM 2.x.x.x. img and its not working properly. It will not detect my device. Ill have to check when i have more time tonight. So far not so good.

"It will not detect my device."
Did you install the HTC driver?
Did you do an "adb devices" first? ( when i do it it says daemon not found starting daemon etc etc or something to that effect, then it shows the device ID -- so in other words, it may have to start some services on your pc first with the devices command before you launch in to pushing files onto an unidentified device -- this last part is just my observation, not gospel)

You can't use ADB for pushing the recovery, unless you have a rooted phone and it boots far enough to use ADB. Otherwise you need to use fastboot, and if you don't have the engineering bootloader - you won't be able to.

Need Help! Phone wont boot up & restore is corrupt

The phone been crashing on me like crazy and it force it's self to reboot, just to crash even more weird. Well the phone won't boot up, it just get stuck at the t-mobile part.

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

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.

Can't open /cache/recovery/log errors. need help!!

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 .

That's the problem. I wasn't able to successfully flash a ROM so it's useless.

Had the same problem with the official MyTouch was the update successful? Just do a battery pull and try turning it back on.
Sent from my HTC Glacier ...Awesome... (MT4G) using xda premium

yes it is official update. already tried battery pull and tried to ruu back to stock

"RUU back to stock" by what?
If you just installed 2.3.4 in PD15IMG.ZIP form - this IS the "RUU equivalent" for MT4G.
Try installing it again.
If it doesn't help - nothing you can do, besides trying to unlock bootloader (don't know if you can, having no OS to boot to) and then flashing recovery from it and any ROM from recovery.

what happens when you flash pd15img.zip ???
