I bought HTC one from Ebay, which was suppose to be Europe version but turns out to be HK version with OS - 2.24.708.4. OTA was not able to install with red triangle error in recovery, after some search i found out that the CID number must be tempered, and i saw that it is 11111 with S-off though it showing to be LOCKED. Which means i can install any custom ROM. I want to have 4.4 with sense 6, So i unlocked flashed twrp 2.6.3 and rooted. I downloaded Android revolution custom ROM (for international version) and flashed it. But afterwards the phone is in bootloop. I can load bootloader and use fastboot along with twrp. But i can't see anything in /sdcard, so data mount is not working it seems. There is no nandroid backup (my mistake ). I repeated the unlock/rooting process when the phone went in bootloop, that might have messed up with sdacrd access, as I flashed revolution rom from there only.
I am aware that by flashing RUU i can get back to stock, but I cant find any RUU for this particular baseband and HBOOT, if yes please let know what should be the closest RUU for this version ? If RUU is not the option, what should i do now ?
Current situation: NO ROM installed, only access to bootloader (fastboot) and recovery with no sdcard mounted.
Also, even though i rooted properly, i cant see "TEMPERED" in the bootloader.
HBOOT - 1.54
