Thanks for the explanation and files xboarder56.
I have a problem here with an Amaze T-mobile, Hboot 1.90.004, it was bootloader unlocked and came with custom recovery. I flashed stock recovery using hasoon's all in one toolkit, and flashed stock 1.43 kernel before i relocked the bootloader. Now, the hboot checks the PH85IMG.zip on the sdcard but it doesn't ask whether if i want to update. I've triple downloaded files to sd card, changed sd cards thinking they might be corrupted but that wasn't the case.
What should i do to this Amaze to ask me if i want to update using PH85IMG.zip.
I tried both 1.36 and 1.43 ph85imgs, but no go...
