I can access the boot loader but if I try to go into recovery I get an icon of a phone with a red triangle and exclamation mark.
If I connect the phone to a PC, no devices are listed under 'adb devices'. I believe I need to install the stock rom (PG59IMG.zip) from the boot loader to recover the phone. I have a couple of different stock roms and although these are automatically loaded by the bootloader without error, the phone doesn't boot.
Not sure if anyone knows of a confirmed clean stock rom or another method I could use.
The bootloader is unlocked but the phone is S-ON, H-BOOT 1.45.0013.
Because you are S-ON, you need to flash the boot image as well. Extract the boot.img file from the ROM, and (while in FASTBOOT USB mode) run fastboot (on the connected computer) like the following:
fastboot flash boot boot.img
AFAIK, adb only works when you are fully booted up, fastboot is what to use while in the bootloader. Blue6IX has a return-to-stock
RUU as well, but we'll cross that bridge if/when we come to it.
