Any suggestions to get this thing working? Or could I just flash the unedited decrypted rom zip posted about and get the same effect?
unfortunately,you cannot run the decrypted ruu while s on,since it does not have htcs signiture.
typically error 155 is solved by simply starting the utility with the phone in fastboot,rather than the booted OS.
if you still have prollems,you can extract rom.zip in this manner:
the .exe utilities can be finicky,so if you have trouble getting it to run, you can extract "rom.zip" in the following manner:
-start the utility
-check the "i understand" box to move on to the next screen
-hide the utility temporarily out of site
-search your C drive for "rom.zip". you will find it in a temporary location(it will be in a different spot each time you run the utility)
-open the folder location,and transfer rom.zip to a safe location on your PC.
-unhide and cancel the utility,youre done with it.
-rom.zip can be renamed to PxxxIMG and flashed from fastboot
if you have trouble finding rom.zip,ive uploaded it to shipped roms: Shipped ROMs
you can flash rom.zip in this manner:
-relock the bootloader by running the following with the phone plugged in and in fastboto mode:
fastboot oem lock
if youre working with a booted,operational phone,you can flsh the file in the following manner:
-open a cmd window
-change to adb/fastboot directory
(cd c:\mini-adb if youve used any of my guides )
-place the zip file you want to flash into adb/fastboot directory
-enable usb debug,disable fastboot,plug in phone
-check for connectivity
adb devices (should return serial number)
-boot to fastboot
adb reboot bootloader
-check for connectivity again
-flash the file
fastboot erase cache
fastboto oem rebootRUU (will put you in ruu mode,black screen silver htc letters)
fastboot flash zip zipfilename.zip (will send and flash the file. dont interupt it while the cmd window shows its writinging,and the green status bar is moving on the phone screen)
*sometimes a file will fail with a pre-update error. this is normal,just enter again:
fastboot flash zip zipfilename.zip
and this time it will finish
-when you get "finished" and "OK"
fastboot reboot-bootloader (takes you back to fastboot)
-reboot back to the OS
you can use this if you dont have an operational phone as well. you just need to manually put the phone in fastboot(select from hboot menu) then skip the "adb" commands and start with fastboot devices
