[Q] Softbrick?

Hey guys!
so, i just wanted to get my HOS back to jellybean stock to get the latest HBoot and now have a big problem. I am S-On and had a O2 branded HOS, changed the CID to 11111111, relocked the bootloader to run the RUU, but now i am stock in the bootloader. My phone is Relocked as i said, S-On, fastboot USB works, but i cant boot to recovery, nor in my rom. i am also not allowed to unlock the bootloader or flash anything else, because i always get this error: " failed (remote signature verify fail)"
would be very nice if someone could help me..

[Q] K2_UL not rooted after update to 4.2.2

Hello guys!
My story is short I had rooted and unlocked bootloader on Android 4.1.2. Then i want to update, so i get moonshine s-off, downgraded hboot, ran RUU and installed updates. Now i have 4.2.2 and sense 5 of course. And now is my problem. I don't have root! What should I do? I tried to flash twrp recovery by fastboot but i getting always the same failure:
FAILED (remote: not allowed). Every thoughts about it?
When you RUUed you had to relock your Bootloader
Unlock your bootloader again then either boot twrp recovery or flash it
Then flash root again

I unlocked bootloader (by htcdev of course), then i flashed superuser. Should working fine, but Titanium Backup told me that don't have root rights...
PS. Of course, after unlock i flashed TWRP
PPS. Problem solved, just flashed SuperSU instead of superuser Big thanks!
Awesome

[Q] need some help installing custom recovery on already rooted device

hi!
i have a k2_ul device, rooted, 2.00 hboot, locked, S-OFF. i rooted it via moonshine last year and later upgraded to android 4.2.2. i never installed a custom recovery but want to install TWRP now.
when i wanted to install TWRP via fastboot i got
Code:
writing 'recovery'...
FAILED (remote: not allowed)
i suspect this ti because my device is LOCKED (i think that it was unlocked after moonshine but got locked when upgrading to 4.2.2, but not sure).
would need some help here. how can i unlock my device again? can i do it without htc.dev and without deleting all user data.
i searched threads in general section but couldn't find my answers, i appologise if i overlooked something.
ps - also, is my hboot 2.00 ok for the latest TWRP?
Here is the guide you are searching for: http://forum.xda-developers.com/showthread.php?t=2541843
Go a bit down to "- To unlock"
And yes, you need to be unlocked to flash recovery.

Can't rollback to Android MM to relock bootloader

Hello,
A few days ago I managed to go back to a stock rom from a custom one. I have a FRD-L09432B360 firmware at the moment, but the bootloader is unlocked. I don't remember the code I used to unlock the bootloader, and I'd like to relock the bootloader so I am able to update to the latest firmwares. I've read that by downgrading to Marshmellow the bootloader will relock itself.
I am following this guide to do so, but when I reboot to apply the UPDATE.APP of the rollback package, it get stucks on 5% for a while, and after a few minutes it reboots, leaving me with the same firmware.
Is there something I am doing wrong?
Is there another way to relock the bootloader without the unlocking code?
Thanks a lot,
Mcat
I still haven't been able to fix this issue? Any idea is appreciated, thanks
You don't need to relock the bootloader to update. Use hurupdater

Possible to downgrade bootloader?

I want to downgrade my bootloader so that TWRP will work again since I havent succeeded in getting it to work on the latest bootloader. However when I try to downgrade the bootloader fastboot gives me an "invalid bootloader" error.

As long as they are the same bootloader revision yes. Or if your bootloader is unlocked you can flash any firmware you like for your device

What firmware are you on now and what are you trying to downgrade to? You're being very vague in your question
