Downgrade while S-ON for sunshine purposes

Feeling an imminent need for this... :)

If you are currently on OS 4.17.605.9 you can downgrade to 4.17.605.5 while s-on by using a signed RUU.

Why might one need this? Perhaps a sunshine app update will support it? Dunno :)


Option 1

For Lollipop
Download DOTTAT_VZWM8_S_ON_5.0.1_RUU.exe and doubleclick. Allow file to extract and install dependencies and then follow on screen prompts.

Option 2

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 3

(use this fastboot https://www.androidfilehost.com/?fid=95784891001612150 )

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.

example



## assuming flash completes and no further flushing/reboots are requested from the cmd output you can now reboot 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!
