HTC One M9 relock help

iHave a Sprint HTC One M9 currently stuck in boot loop displaying
"This build is for
development purposes only
Do not distribute outside of HTC
without HTC's written permission.
Failure to comply may
lead to legal action."
I'm not sure of the CID nor firmware version(i'm sure it was the latest 3.41.651.4.) iForgot to backup my device before rooting(stupid iKnow.) I've already found the RUU for 3.41.651.4 it's saved to my SD card. iCan still reach bootloader, recovery&download mode, should iJust enter recovery&flash the RUU? iAlso have S-ON. iWould like to relock the bootloader&start the root process anew. iUsed TWRP 3.0.2 as well as Super SU 2.76 during my first initial attempt. I've already tried to lock the device once but when iType adb devices into the command window no device is displayed.
I'm not sure where to go from here. Can someone help?:confused:

Need rooted stock TW ROM that won't re-lock bootloader or touch recovery partition

Short story: I need a TouchWiz ROM that I can flash from TWRP that won't re-lock my bootloader or touch the TWRP partition. What's the best one to use?

Longer story: I have SM-G900V running CM 13 that is currently unable to get a GPS lock unless airplane mode is enabled. So far I've been told the only fix for this is (high level instructions):

1. Nandroid backup of CM 13


2. Flash TouchWiz ROM


3. Get GPS lock in TouchWiz ROM


4. Restore CM 13 nandroid backup

Some of the troubleshooting steps involve root, hence the need for a rooted ROM. Can anyone help?

honor 7 bootloader relock issue on PLK-L01

hi,
I have successfully installed multitool and then using multitool - unlocked bootloader , installed TWRP and installed super SU.
I have tested the phone for native call recording using the changes suggested. once testing is finished I wanted my phone to go unroot and relock the boot loader. I have tried that but it is not working. It is coming up as FAILED (remote root type is at risk).
I have also updated after that to OTA B370 successfully. I have checked with root check that there is no root access to the phone. how can I relock my bootloader on this phone please. thanks in advance.

Can I re-lock bootloader (or is it needed)? Must send out for warranty.

The camera module's pooched (started failing in 5.1 with not being able to focus on near objects, now it won't run at all). Weird shenanigans in 5.1 as opposed to the stock 4.3 that it came from. In 4.3, I can run Flashlight, but Gallery crashes when Camera is run. Front camera works intermittent - rear camera not at all. In 5.1, I cannot run either the camera app or Flashlight (quick access menu) and if Flashlight is pressed, the LED will shine for 5 seconds, turn off, and the Flashlight icon will stay half-lit until the phone is soft-reset. 5.1 gives the notification "cannot start the camera - make sure 3rd party apps (such as Flashlight) aren't running" (with everything disabled).

The only constant is that the rear camera will not function in either Android environment.

It's still under warranty with Wind, do I even need to worry about the unlocked bootloader or no? Either of these were stock Android with no root.

[Q] No update after relock?

So I restored stock system and boot, flashed the stock recovery and locked (relocked) the bootloader. (I'm S-On)
Is it normal that I still can't take OTA updates?
