[Q] Desire z, dead! frezzes in fastboot mode.

Hi,
I have Desire Z, that is dead, the only thing i can access is fastboot mode, yesterday i was able to enter "fastboot oem rebootRUU" and it seems to be ok, but today my phone frezzes every time to something i fastboot mode, og sends comands to it.
can som one help me, my phone is not rootet,
i have tried to flash recovery, but i'm not allowed, i need help, some ideas?
every i have put the P10IMG on Sd card, the phone starts to update, but it frezzes in the first step ( bootloader )
some info:
if you need more, just ask, and i wil provide it.
S-On
Hboot 0.85.0013
radio 26.10.04.03_m
( sorry for my bad english)

thirst thing i would try is to wipe cache...
so enter bootloader, choose recovery = a red triangle should show up then push power & volume up; select wipe cache and reboot
if this didn´t help do a foctory reset = same procedure as above only select factory reset in recovery...
...and remove the PC10IMG.zip from your sdcard so you can enter recovery

I have tried that, but the bootloader, frezzes, and the phone shuts down, and vibrates many times, then its dead again.
every thing i do in bootloader, results in a frezz, and i must start over again.

hm.. not good
another thing you could try is to enter usb fastboot mode (power & tp) connect your phone to pc and then start the ruu (.exe) on pc and maybe it does the update..
after it´s done enter recovery and wipe...
be sure that the ruu is higher or the same like the one previously installed and that it is the right one (asia, europe, bell, ...)
you can´t flash a recovery or anything trough fastboot if you do not have eng hboot or a rooted phone
EDIT: or when you in fastboot mode start cmd.exe go to your tools and type "fastboot oem boot" - maybe you are lucky

When i start the update it stops at the first step ( bootloader ) and its the same version, so it starts, but stops right away.
when i but it in recovery mode, the phone just vibrates a lot, and shuts down.
is there away to install a custom boot, or maybe root the phone now? nothing seems to work.. please help me..
every time i type somthing in cmd, it states to many links as an error. when i type "fastboot oem rebootRUU" the answer is "to many links"

sry, but i think there is not much you can do anymore...
maybe someone else knows better

Trying to recover M8 that suddenly stopped allow WiFI/Mobile Signal

I have a barely functioning M8 and I could really do with some help.
A friend gave me his M8 a few weeks ago, the M8 would not boot. It was getting stuck on the boot animation. From what I could tell, I think the device had been interrupted during an update.
The M8 is Europe model, with MM installed. Bootloader was unlocked at HTC.com but is still S-ON. CID is HTC__001 and MID is 0P6B10000
I installed a custom recovery and flashed the latest ARHD. Finally the device booted fine and showed the correct software/baseband etc. in hboot and settings/about phone. Made test calls etc. it worked fine.
A couple of weeks later the guy is back to me saying the phone suddenly stopped sending/receiving signals, wifi no longer turns on and the phone will not acknowledge any SIM that is inserted.
First look shows the baseband, in settings/about phone, now shows "unknown". But booting to the hboot shows the correct radio version.
I went searching XDA/the internet for the MM radio.img but was never able to find it.
So next I looked for the Europe MM RUU, I needed to ensure that the radio was repaired, which I apparently found at this url:
Code:
https://www.androidfilehost.com/?fid=24369303960687057
it has a file called 0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4_Radio_1.29.214500021.12G_20.72.4196t.01_release_464360_signed.zip
Now I have come across several XDA threads that say this file show be renamed to 0P6BIMG.zip put it on the root of the SD card and then boot to hboot where it will automatically find and install it. But with this file, when doing that it says image fail press power to reboot and never installs the file.
Next I came across an XDA thread that said I need to boot the phone into RUU mode and use htc_fastboot to flash the file, having renamed it to RUU.zip. but despite this being a 1.6Gb file it is detected as 53Mb by fastboot and again fails saying the file is corrupt.
I downloaded the file several times and no matter which method I us, it is the same result it will not flash the RUU. I have found a different hoster with the same file, same end result.
I need to fix this poor M8 and at this point I am out of ideas. Please, if any one can offer some advice on fixing this thing, I would appreciate it.

1. Is the bootloader unlocked when you flash the RUU.zip ? It needs a relocked bootloader - command : fastboot oem lock
2. It needs RUU mode to run the RUU.zip - command : fastboot oem rebootRUU

Many thanks for the response.
1) how do I unlock the bootloader once it has been relocked? I believe it is problematic so I have thus far avoided relocking.
2) Yes, the phone was in RUU mode, as my post explained. It had the silver HTC on the screen.
I have already followed that guide and it wasn't successful. I am assuming due to the unlocked bootloader. But as I explained the PC only uploaded 53Mb of a 1.6Gb RUU to the phone, I don't know if that is due to the unlocked bootloader or not.
Do I have any other options to repair the radio (and any other partitions without relocking the bootloader and flashing an RUU ?
Kind regards

A S-On device must have a locked or relocked bootloader in order to install RUU or firmware.zip
Only on S-Off device you don't need to relock bootloader.
To re unlock the bootloader, just fastboot flash the Unlock_code.bin that you can get from htcdev.com
command - fastboot flash unlocktoken Unlock_code.bin
You also can try to flash a full signed firmware.zip instead of RUU.zip to see whether that will fix your problem... but still require a relocked bootloader on S-On device. (RUU.zip is highly recommended)

Bootloop on HTC M9

Hi, as the title says my HTC is stuck in bootloop and the OS wont load. Tried the data wipe clean and the factory reset it the problem was not resolved.
Read about 101 solutions but each the my problem with all these solutions is it requires my phone bootloader to be unlocked and S-OFF. My phone bootloader is Locked and S-ON, now a lot of you will tell me to unlock the bootloader by turning on the developer options in my phone but the problem is how do I do so when the phone doesnt load the OS at all?
Summary :- Bootloop
Bootloader Locked
S-ON
Doesnt Load the OS for me to enable the Developer Options
HELP!!!
Thanks

Put the phone in download mode, plug it into your pc, obtain and run htc_fastboot.exe with the cmd command "fastboot getvar all" (must be executed from the fastboot directory/folder)..
Paste the results in your next post..
