One should also be VERY careful that you have enough battery % left before you perform the RUU update. The software checks if your battery has sufficient voltage before it proceeds, otherwise it is impossible. And, if you have a custom ROM with a bootloader which has just been re-locked, you can get into trouble.

The reason is is that the phone will not boot into the custom ROM with a relocked bootloader, nor will your custom recovery (CWM or other) load and you will have no access to it in order to charge. You will be stuck in fastboot mode in which it's impossible to charge.

The following little script saved my ass when my battery was too low in order to even re-unlock the bootloader in order to get back into the custom ROM. (fastboot commands also check your voltage before it can perform a re-unlock).

Here's the script if you need to charge your battery if you're ever stuck in fastboot with a custom ROM, re-locked bootloader, and a low battery.

You need to create BATCH file that essentially reboots the phone every 6 or so seconds in order for the phone to turn off sufficiently long enough to accept a charge. (And, no, simply attempting to turn off the phone and plug it in turns on the screen in fastboot mode and it doesn't charge.) This was the ONLY way I could get enough charge to either re-unlock or perform an RUU update. Once your battery reaches around 1.68 V (1,680 mV), you should have enough charge to re-unlock it to charge normally the rest of the way so that you can again re-lock the bootloader and update with the RUU. Here is the script:

" @echo off
:start
fastboot getvar battery-voltage

fastboot reboot-bootloader

ping /n 6 localhost >nul

goto start
"

how do you extract a rom.zip from an ruu?
that was exactly where I get confused & thinking about.. :D

How will we extract rom.zip & cook a stock rom to be flashed?!

for example my CID is : HTC__J15

And i have already used a week or two ago : "RUU_ENDEAVOR_U_ICS_40_HTC_ARA_1.28.415.9_Radio_1.1204.103.14_release_25679_signed" to get back to stock and wait for OTA... but now running ARHD like written in my sig.

now what will I do??

I am really curious about updating radio & hboot through OTA or RUU since Mike is still not very sure about if his ARHD already updated those or not...

Guys does anyone know what is the RUU for VODAP102? I know it is vodafone Germany but finding it hard to figure out what is the original ruu file name from the shipped rom collection thread. Can someone please tell me what file I need to download for voda Germany?
