Hello, here is a very simple guide to be able to use revone to s-off on the 1.31 update.

Make sure you have dev unlocked and you flashed a custom recovery (CWM or TWRP both work fine)

After that, you need to make sure adb works (if you can't figure out how to do any of this, I will not help you. If you can't find out basic things about Android, then you shouldn't have s-off)

So, as we all know, HTC has made it so with newer bootloaders, you cannot downgrade to older firmwares. Well, this is true except when the software version changes but the hboot version doesn't. So all we need to do is this:

Boot into recovery


adb shell
echo "1.29.651.10" | dd of=/dev/block/mmcblk0p19 bs=1 seek=160
adb reboot bootloader
fastboot oem lock

then just flash an RUU of 1.29 and it'll work out. All you do is flash the misc partition to contain the proper mainver and it works.

Flash an ruu.zip or can it be ruu.exe also? Should revone be done after the ruu?

Just to be sure cause I'm having issues. This will allow me to flash a 1.29 ruu after having the 1.31 update? This could save me!

So I didn't see this post but did something slightly different and it worked perfect.

Unlocked the bootloader via HTCdev
pushed TWRP for Sprint
Flashed SuperSu

Then followed the revone instructions particularly step 3 su (and going onto the device to grant access.) and everything worked perfect and never had to downgrade from 1.31.

Indirect... you saved many a phones. I have been searching for this and read many a post where people were scrambling (not necessarily for s-off, but the fact that they relocked the bootloader and could not run the 1.29 RUU. I encountered the same thing but just unlocked again and flashed my stock nandroid. Thanks!

If I run just...
Boot into recovery
adb shell
echo "1.29.651.10" | dd of=/dev/block/mmcblk0p19 bs=1 seek=160
adb reboot bootloader
fastboot oem lock
then just flash an RUU of 1.29

Does that leave me with a stock build and s-on? In the event I had to part with the One, etc.
