As many of you are aware, flashing roms to our phone comes with risk. That risk is dimished by the availability of an RUU for our phone.
I have created as much of an RUU as we can put together at this point. This is for s-off users only. I repeat...s-off only.
This zip is an RUUmode/hboot flashable stock RUUish compilation of the current boot/hboot/system/recovery/radio/firmware images. Just like an RUU... this WILL wipe your phone (internal memory). IF you are able...backup data prior to using this. This works EXACTLY like an RUU for s-off users. Two options exist for using this zip. This will land you on STOCK kitkat 4.4.3 pre-rooted with stock recovery. I have tested this on my
NOTE...HTC started preloading some files to /data on the latest Rom. There's not a clean way to add them to an ruu so please flash the following file in recovery after getting your phone back to stock. If you don't, the only problem would be that gallery is missing the sticker files under edit.
If coming from 4.4.4 firmware you will need to flash 4.4.3. in RUU mode prior to flashing this..
Copy 0P6BIMG.zip to root of a physical SD formatted to fat32. No exfat! No internal storage! Must be external SD formated to fat32!
Reboot phone to bootloader and follow prompts once RUU is detected by phone.
Option 2 (Might not be working!)
Fastboot RUU mode . This method assumes you have a working ADB/Fastboot directory on your PC. Download RUUish file and place in your working fastboot/adb directory. Boot your phone to fastboot mode and connect to PC. Issue the following commands.
fastboot oem rebootRUU
###while in this mode your phone will display an HTC logo on the screen
fastboot flash zip 0P6BIMG.zip
##while in this mode you will see an HTC logo on the screen and a green status bar across the bottom of the screen. When command output ##completes it may say reboot required to flush etc... if that's the case issue a "fastboot reboot-bootloader" command and restart option 1 again.
## assuming flash completes and no further flushing/reboots are requested from the cmd output you can now either do one of two things 1)##reboot or 2)flash a custom recovery. IF you simply wish to reboot the system you can issue "fastboot reboot" which will reboot system.
## expect a good 5 minute plus first boot!
Optional If you wish to flash a custom recovery before leaving RUU mode you can. This is helpful if you have relocked for any reason as you CAN flash a recovery using this method while locked (since s-off). Download the ruuM8TWRP_2_7_1.zip below and place it in your working fastboot/adb directory. Once in place, issue the following command.
fastboot flash zip ruuM8_TWRP_2_7_1.zip
