HiT THANKS IF THIS HELPED YOU. AND POST A REPLY FOR IMPROVEMENTS

Nloooo

Respect for the effort but there are a few misunderstandings:
1. Locking of bootloader??? Why for God's sake??? A ton of people lost their hair trying to unlock it!!!!
2. Downgrading? What kind? You have to explain the reason (1.03 bootloader or what)
3. Quoting "2. Download the HTC Desire ROM (RUU)". Don't mix rom with RUU (Rom Update Utility), they are not the same.
Plus: which RUU to download, you have to explain, what version (Android related), which region based (for branded devices)...
Ok you mentioned goldcard-explain why (for branded devices)...
My recommendation: suggest 2.3 RUU, it's usable with all phone types (amoled or slcd) and all regions (no goldcard needed applicable for all brends).
Also you have to mention that all RUUs can be used from PC while phone is connected via USB.
4. S-off process: revolutionary-yes but for 0.93. and 1.02 hboots, for older versions of hboots alpharev reflash utility needed
5. Rooting: Unrevoked-yes but when you don't use Revolutionary (gaining s-off using Alpharev reflash utility).
Revolutionary itself gives option to flash recovery (Clockwork Mod) which you use to flash Superuser app to gain root access (explained on documentation page for
Revolutionary, all you need is to read http://unrevoked.com/rootwiki/doku.php/public/revolutionary)
6. Quoting "The process will flash your recovery partition back to stock" - no, Revolutionary will flash ClockworkMod recovery.
7. Quoting "The downgrade installs an official stock HTC ROM with Hboot1.02 (You can s-off with revolutionary and after it You can flash any version of Hboot)" - not necessarily the hboot will be 1.02, it depends on which RUU you choose to flash.
Plus:
Downgrade package contains virus, warn potential user - what is it, a virus that will ruin their PC or just an exploit used to gain access to restricted phone partitions.
I hope I helped...

Try the 2.3 RUU. Check my sig.

my phone was sent for repair, got new motherboard and after one hour of using it he just froze. I removed my battery and put it back, after that it stuck on HTC logo screen. So I went to flash RUU but I couldn't install it I got singarure error, so I made bootloader unlock and after that I don't know what to do next.
Nothing in bootloader it says: "checking PB99IMG.zip - no images found"
so I really don't know how to make downgrade because I can't get into the OS I can't flash RUU's and PB99IMG's, some PB99IMG's are read but after that it just stops, I don't get the screen with recovery...OK, boot....OK, etc (I don't get parsing message). He just get's in the bootloader again :/

PLEASE HELP ME TO FIND THE RIGHT RUU or any other method that would work.
bear in mind iam unrooted.
What am i supposed to do to fix my phone? any clue?
via RUU or .... ............

If your aiming for a stock rom, Just create a goldcard and try flashing your stock rom.
You can extract the rom.zip file in ruu by
The process:
- Download a RUU from anywhere (you already have one)
- Open/Run the .exe You'll get something like this
- Click the Start button
- Select the Run command and type in: %temp%
- Search for a folder that has a bunch of characters and looks somewhat like this: {XXXXXX-XXXX-XXXX-XXXX-XXXXXXXX} just keep on searching in each folder, if you have patience you'll find it.
- And inside that folder should be another folder that looks the same, and has the format above.
- Find a zip file called rom.zip -
-Rename the rom.zip to PD98IMG.zip
If you already created a goldcard. put the PD98IMG.zip in the root of your sd card
Go to bootloader and pressing -volume and power button.
Rom zip will automatically detected and you will be ask to update.
Hope it helps "newbie here" :fingers-crossed:

Iam not aiming on stock. actually i dont care. i just want my phone back working.
i dont have a goldcard. can i make one with unrooted and locked phone?
i tried with flash from sd card extracted rom and renamed as PD98IMG - it comes to do you want to update? pressed vol.buton up than shows update in progress and stuck for over a hour.
doesent work
thanks for effort

Its easy to create a goldcard, any sd card will do.
Links is http://forum.xda-developers.com/showthread.php?t=970157
if you cannot get your cid just use the attach file goldcard.img below
i dont know if it would work, but since you haven't find any solution yet, you could at least try.
Hope it helps your phone...:fingers-crossed:

Have you tried with a different sdcard? have you also checked the md5sum or the RUU? maybe you can flash it in fastboot (read the guide in my signature to find out how)

[Q] Unrooted HTC Desire Z on boot loop

Hello everyone. First of all, please bear with me for I am absolutely a newbie here and have a very limited knowledge on android(or any other) os. Not much of a tech savvy so please, go easy on me. I just wanna try the possible solutions you guys could give me and help my sis save hundreds of bucks from acquiring new phone or going to pricey repair shops.
The phone's HTC Desire Z A7272 (unrooted)
So here's the problem: When I try to turn on the phone, it's just stuck on the HTC logo(w/o the quietly brilliant tag below it). Prior that, my sister was just using the fb app when it suddenly froze. She waited for a couple of mins for it to respond, but nothing happens so she pulled out the battery. When she turned it on, it's stuck on a boot loop (HTC logo+quietly brilliant). We tried removing the battery for a while to let it cool before placing it back but still, same thing happens. We even tried booting it after draining the battery and having it fully charged, w/ and w/o the SD card and sim, but to no avail. Now, it's still stuck on boot loop: HTC logo(w/o quietly brilliant below) then green arrows icon with gray loading bar.
We're able to access the HBoot and here are the details:

system: 0xADA36D23
On Fastboot, I tried the Reboot and the other options but it just goes on a boot loop.
When I select Recovery, it boots on logo, then there's green arrows icon with gray loading bar below, and then a red triangle with down arrow inside. I read somewhere that it's the stock recovery and from there I could wipe/clear cache, but then when I tried pressing and holding the Up+Down+Power buttons, it says E: couldn't wipe cache/ mount command/recovery - something like that.
When I select Factory Reset, it just loops on the HTC logo and the green arrows icon.
I tried installing HTC sync and connected the phone via USB, but it can't detect the phone(though the PC can, as mass storage and on HBoot it shows 'HBOOT USB PLUG')
My sis downloaded an RUU from HTCDev and copied it to SD Card. She said she was able to Clear/Wipe Cache Partition and data
via bootloader but when it reboots, it's still on the same state.
After looking on some threads with similar issue, some say the ROM may be corrupted so I downloaded stock recovery, stock ROMs (changed the file name to PC10IMG.zip) and copied it to the SD card hoping that it'd reinstall the ROM but still, no effect.
Probably, the ones I've downloaded aren't compatible to the unit, but I don't know how and where to get the exact official ones for the device.
Others are suggesting that I should flash a ROM, but then it requires to root the phone - I don't wanna risk doing it 'cause I'm afraid I might do more damage.
Is there a way to simply reprogram or reformat it(just like what you do on PCs) with fresh/original stock ROM?
Some say that it could be hardware damage (eMMc/Mobo) - hopefully not >_< , but others tell that since we could access the boot loader it's more likely a software issue.
We also see people mentioning things like Gold card, adb, kernels, etc. but we just get more confused upon reading them(too much tech jargon to take)
Are we doing everything wrong? Please let us know.
Most of the solutions we find online are for rooted phones. Hers isn't and just want her phone to get fixed.
Please help. We're really clueless. Do you think this is a hopeless case?
Sorry for this very long post, but I hope I was able to explain the problem well.
Thanks for taking your time in reading this post. Any help would be greatly appreciated.

Sounds to me like its a fried eMMC, in which case there's nothing that can be done.
Seeing as the phone is completely stock, there's not many ways to check if this is the case, but trying to flash a new stock rom won't hurt the phone at all.
Any chance you can run (in fastboot mode) 'fastboot getvar all' and copy those results here?

Hi, i've had a similar problem and found a suitable ruu rom in 6th attempt
i've tried with 5 random rom's until i've downloaded one with radio version of my Desire Z.
try with official from shipped-roms_dot_com under Vision folder and search your rom with radio version (26.10.04.03) - there are 3 available;
change zip name, save on sd and try :good:
p.s.
maybe your emmc is still ok

Hi merslavics!
Yep, phone's okay now I was able to find the right ruu after reading through the threads here regarding that matter. You're right, we should take note of the CID and radio versions to get the right match. Success after 3 attempts! Cheers!

Taking a photo caused brick?

Hi, I took a picture of something with my phone and then locked it. After checking it again the screen was flashing between blank and a stock wallpaper. I reset using the power button and volume up. Ever since then my phone will not load past the HTC splash screen, not showing my carrier splash screen and instead just being stuck on a blank black screen. This is a stock phone which I haven't even attempted to modify.
I have tried to clear the cache, factory reset and all of the different combinations of holding both the power button + both volume buttons etc. I've tried booting without a sim, without a memory card or with one of each. Still no dice.
If anyone could provide me with the answer to my issue that would be amazing.
Thanks!
Edit: I should add I've tried using adb/fastboot and it will not detect my device when I type 'adb devices'.

ADB only works when your phone is powered on. Not when you're stuck at a boot screen. You'll have to boot into the BL and type a few fastboot commands.
Turn your phone off completely.
Press the following combo:
Power + Vol Down
That's the HBOOT menu, press the power button once if FASTBOOT is highlighted. It will go to fastboot mode.
Type 'fastboot devices' and if it shows your serial number, proceed to type this command:
fastboot getvar all
Once you get that, copy the result without the IMEI and Serial Number. Post the rest of the stuff here, so we can guide you on which RUU to flash.
Should be a simple fix hopefully.

Sadly, Three UK RUUs are impossible to find.
Your bootloader is locked I think and you're S-ON. Making things a bit hard for you.
You can try to unlock the bootloader through HTCDev, once you do, flash TWRP recovery, download the 3 UK backup from ckpv5's thread and restore it to your phone. Then flash the stock recovery for your build and re-flash that. Wipe data and reboot. You should be up and running.

See bold. What do you mean here? Re-flash with the stock (non recovery) backup?

Think he meant "Then find the stock recovery for your build and re-flash that".
In any case, just flashing the TWRP backup (nandroid) should get the phone back up and running. Restoring the stock recovery is only necessary to get future OTA updates.
In any case, even if you want stock recovery, I suggest waiting on restoring stock recovery until after you've restored the nandroid, rebooted, and confirmed it boots properly into OS. That way, if it doesn't boot for any reason, you still have TWRP and can try to restore again.
Here's the TWRP backup collection, if you haven't already found it: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
You'll find the stock TWRP backup (and corresponding stock recovery) for 6.13.771.4 there.

Oh, makes sense. Just to make sure, I need to wipe data by just using the 'swipe to factory reset' option in TWRP right? Then I should be good to go? As without wiping the phone is still just a moderately heavy paperweight.
Edit: Factory reset via swipe in the wipe menu, rebooted and so far all is good. Currently optimizing apps.

It tells you exactly what to wipe in the thread I linked, top post, step #8.

Phone is back to normal working condition so far. Thanks guys!

Sorry about that. Wasn't reading what I typed.

Fastboot

I need to unselect fastboot in my settings, but my phone wont even turn on pass the htc logo. Can someone please help me?

You don't really need to unselect "Fast boot" in settings. Its not even an option in Settings anymore in Lollipop or Marshmallow.
Even if you are still on Kitkat (few people are) the only thing that "Fast boot" affected, is that it prevented booting into bootloader from a power-off condition. But if you force a reboot (which is distinctly different from power-off), you can still get to bootloader:
1) Hold power + vol up until phone reboots (may take a minute or more, if you are stuck on the HTC logo screen)
2) Once the screen goes dark to reboot (but before the HTC logo screen comes back up) let go of the buttons, and hold only the vol down button. Don't let go of vol down, until you see the bootloader screen.
3) If it didn't work, you just didn't get the timing right. You either started pressing vol down too late, or let go too early. Just repeat steps 1 & 2 above until you get it right.

Thank you for help. I already unlock my m8(by HTC dev) and I get recovery and install from recovery superSU zip file. But i cant finished superSU parts(so I am still without s-off and root?), because my telephone still cant load android(I am still on ``HTC one`` logo). So question can I put original firmware into memory card and reinstall all system?

Many folks get fail to boot after trying to root; due to using an old SuperSU version. If the phone is on Marshmallow (Android 6), you need SuperSU 2.52 or later (2.65 is recommended as the latest stable version).
If this is the case for you (on MM and used an old version SuperSU) then flashing SuperSU 2.65 should allow the phone to boot (and with root).
You should also use current version TWRP 3.0

yes i am using TWRP 3.0.2 and superSU version is 2.65. I am still stuck on `HTC ONE logo`.

Probably your best bet is to restore a stock nandroid that matches your version.
You didn't make a backup in TWRP before rooting? You should always do that, for this very reason (in case you run into problems and need to restore).
For more specific help on what version, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

Its not clear, were those the versions you used to begin with, or you tried them after my recommendation?

I tried those versions before your recommendations.

after several tryings, telephone trying load. I mean 'Android is starting optimizing app 21 of 133'

And still after optimizining stuck on ``green HTC``...even i can regulate sound, but this is it.

Not firmware but a RUU zip.
Note : MUST relock bootloader
Boot to fastboot/bootloader mode then run command in terminal
fastboot oem lock
What you need :
1. a MicroSD
2. Download the 6.12.401.4 RUU zip - https://www.androidfilehost.com/?fid=24369303960687057
3. Rename the file to 0P6BIMG.zip (that's a zero not "O")
4. Put the 0P6BIMG.zip on your microSD
5. Boot your device to bootloader/fastboot then select hboot, it will scan the update zip and ask whether to update - volume up to select yes
6. Let it do its stuff
7. Once completed, reboot
8. Delete the 0P6BIMG.zip on your microSD (or remove the microSD)
9. done

I to do relock, but still cant find right file in microSD card...why? I check several time of file name...

And now telephone cant even load himself, recovery etc. How to back from RELOCKED?

Having the bootloader unlocked or not (relocked, locked) , has nothing to do with it finding the file. It will find it either way (but fail to install if bootloader is unlocked).
You sure you named the file properly (first character is "zero" not letter "O")?
Also, make sure you turned off the Windows option to hide file extensions (which is ON by default). Otherwise, you may have named it 0P6BIMG.zip.zip and not know it.
