TWRP not installing

Bayernholic · Jun 24, 2017

I recently unlocked my T-Mobile HTC U11 and I'm trying to flash TWRP recovery on it. However, when I enter the command "fastboot flash recovery twrp-3.1.1.img", command prompt gives me an error "FAILED (remote: Not allowed on PRODUCTION device)." My Fastboot screen shows me:
FastBoot
Product name - QC_Reference_Phone
Variant - MSM UFS
Bootloader version -
Baseband version -
SECURE BOOT - PRODUCTION
SECURE STATE - S-ON
DEVICE STATE - UNLOCKED (U)
***Software status: Official ***

Any Help would be appreciated

I haven't unlocked yet, but did you try and use htc_fastboot.exe instead or vanilla fastboot? Not sure if it is required or not.

Well this is my first HTC phone so I'm not exactly sure what htc_fastboot.exe is

but if I find a link or something I will check that out. Thanks :good:

Did you unlock the boot loader from htcdev with the code that they emailed you with? If the boot loader is locked it will reject the twrp flash.

Flash recovery in download mode, not in bootloader mode.

I tried that and it did install correctly but now when I go to Reboot to Recovery, it says " Your device can't be check for corruption. Please lock the bootloader" and proceeds to reboot my phone. I tried to lock my bootloader with fastboot but when I type "fastboot oem lock" it gives an error saying "Failed (remote: unknown command)"

Check MD5 of twrp-3.1.1-0-ocn.img. Should be 925ebc3f6416dd8ac7b509670ca26095.

When booting to TWRP use bootloader mode(does not install TRWP on Device), Installing TRWP requires Download Mode(replaces stock recovery with TWRP).

Ok, I understand.
So do I need to backup the stock recovery first before change it to TWRP recovery. If yes how to backup?

Ok. It's done. Thx alot.
Another question I want to ask. Why before I install the TWRP Recovery, when I go to recovery, the screen only shows Red Phone with Cross?

It has been a long time since I have seen that, but I do believe that is what the stock recovery looks like.
