If your s-on lock the bootloader first is all that's required to flash the RUU

Ok im s-off

So just to clarify steps for flashing this RUU.zip...
1) put phone in bootloader
2) *optional relock bootloader (i cant remember if i unlocked it)
3) fastboot oem rebootRUU
4 fastboot flash zip ruu.zip * twice
5) fastboot reboot-bootloader

yes
relock not needed with s-off
Ok thanks.

If this works this time around i will be back to stock. Should i just flash the firmwares 4.xx, 5.xx as before?

Finally after i flash the ruu.zip will i have to redo s-off?

Well the ruu.zip worked im back to 3.17
Tried to flash 4.xx firmware but still getting fail 32 header error..
Should i just flash the 4.xx zip? or should i just update via the setting on the phone??

So you have a bunch of different links in this post, are they all different? Do I need them all? What if my only way to communicate with my phone is through the TWRP and Command Prompt... For example, I can't just copy the .ZIP files to a folder location due to the fact that my phone doesnt connect to HTC Sync... I just want to put Android back on my HTC... I feel like this is what I need but I'm so dam confused with all your different links, and everything...

I can use TWRP, and Command Prompt, and ADB... But after my phone loads the HTC Screen on startup.. It proceeds to a Black Screen... and then stays on that screen until I go back to Fastboot to power down, or use my TWRP to power Down...

I Just want ANDROID ON MY PHONE... Why cant I just figure this out already... I am stuck and confused.. Please CLARIFY this for me..

  • clsA just provided options for those who are in different situations. Since, you have TWRP installed you can use the first link which is the Guru_Reset for your phone. If you have a good wifi connection you can download it directly to your phone and install it within TWRP. The instructions for using the Guru_Reset is the second link.
