Hi CafeKampuchia / Zombie591

am having this problem with my device, it says "No OS" and it all happened because of Supremo_v30.....

i cannot install any custom Rom, nor can i flash a stock rom, i've tried all the possible ways but no avail..tried to update custom JB it gets updated but keeps looping boot,
I tried even to flash ubuntu on it but it says could not mount "sd ext"

i can get only till Hboot, i get options such as fastboot, Recovery, Factory reset, simlock, Hboot USB, Image CRC and show barcode.

Before you start, you will need to set up your computer to properly recognize the phone. You probably did this when rooting originally, but just in case... Install SDK tools for Android, Java runtime, and HTC Sync.

About HTC Sync: The only reason you need HTC Sync installed is for the USB drivers that come with it. But the program itself has been known to cause conflicts. Make sure that HTC Sync is not running in the background by opening Task Manager in Windows and killing it if you find it lurking in there.

Here we go:

1. Download the correct RUU (ROM Update Utility) for your device from androidfiles.org. Make sure you download a Primo_C RUU for a CDMA device (no sim card) or a Primo_U RUU for a GSM device (uses a sim card)!! Also make sure you get the correct RUU for your carrier.

2. Charge the battery above 50% or for at least one hour. If the battery dies during the flashing process, you could hard brick the phone!

3. Run the RUU until the wizard comes up. While the RUU wizard is open, find the temporary folder it created. (Open Explorer in Windows and type %temp% in the navigation bar.) There will be two folders with long encrypted names. In one of them you will find ROM.zip. Open it with 7zip and extract recovery.img or recovery_signed.img. Put it in the location were you've installed Android SDK tools. This is the stock HTC Recovery and it is needed to run the RUU.

4. Boot the phone into bootloader (power off, hold down volume and press power) and highlight FASTBOOT using the volume rocker and pressing power. Then connect the USB cable. You should see FASTBOOT USB.

5. Open a command prompt in Windows and navigate to the folder where you installed Android SDK tools. Flash the stock recovery extracted in step 3 above using the following command:

Code:

fastboot flash recovery recovery.img

or

Code:

fastboot flash recovery recovery_signed.img

6. Relock the bootloader using the following command:

Code:

fastboot oem lock

7. Re-run the RUU. It will restore the device to it's original condition, locked (though *** RELOCKED ***) and unrooted.

Once the install is done you'll have unlock the bootloader again using the token you already have from the first time, reflash CWM Recovery and re-root. All this will be 10x easier than the first time.

If you do re-root your phone, be 100% you backup the stock ROM in ClockworkMod Recovery before making changes!

I ran HTC's ROM software for my HTC One sv Boost K2_CL, did the temp search & found the ROM zip. I have winzip ver. 18. When you go to unzip it gives an error. I tried inside the temp folder because I had copied to another file where I have the HTC ROM software and it still would not unzip. Downloaded the 7zip software (nice, see where you can extract to ROM) and it gets error trying to unzip as well. I tried to just extract, another different type box opens and it has a password entry on it. So HTC has password protected to prevent using their ROM flasher if your phone is having trouble.
All I can think of.
