[Q] Fastboot 'FAILED (remote: signature verify fail)

---

This error happens whenever I try to use Fastboot. I don't think it is dependent on the file being flashed, as I have tried a number of recoveries and a few system.img files.


How can I fix this? I need a working fastboot to be able to install a ROM and fix my recovery.

Okay, this is solved. I was rooted using the one-click method, but it seems I can't flash anything in fastboot unless my bootloader is unlocked. So I used the command

fastboot oem unlock

And now everything works perfectly.

same error is there with my wildfire s..
nothing is working..
it gives error..
(bootloader) signature checking...
FAILED (remote: 12 signature verify fail)



please help..!!!!

1) You're in the wrong forum.
2) To use fastboot you have to unlock your bootloader with HTCDev tool, and you still won't be able to flash radio/splash/some other partitions.

i tried unlocking the bootloader.. but after running the RUU, during update something went wrong and a htc logo came up with "!" in all corners..

what do i do now? please help..!!

To unlock the bootloader, you don't need RUU. You should have just used the HTCDev tool.
I don't know what went wrong, soI can't help you. Try looking for help in Wildfire S forum.
