[Questions] Relock Bootloader before flashing RUU? - HTC U12+ Questions & Answers

Hi,
My HTC U12+ just have a broken screen. I wanted to revert to original by flashing the RUU zip file. May I know if it is necessary to relock the bootloader before flashing the RUU?
Thanks in advance.

No, it's not necessary

Thanks for replying.
Some people said it is required to ***RELOCKED** the bootloader first and some said no need. So I relock it by FASTBOOT OEM LOCK just for safe.
And I also followed the guide for U11 and it worked.

Quick Qestion About Relocking The Bootloader

Couple quick question regarding locking the re-locking the bootloader.
First off I have the ATT One X rooted with TWRP Recovery. To go back to stock if I so choose, would I have to reflash the stock recovery then do fastboot oem lock before running the ruu or can i just fastboot oem lock the bootloader without flashing the stock recovery, then run the ruu?
I think I have to reflash the stock recovery first before relocking the bootloader. If that's the case, can someone link to the stock recovery img file?
I also read that if you're currently rooted and has your CID, you can update to 2.20 and root again...is that still the case?
Thanks

You can just fastboot oem lock, the RUU will take care of restoring the original ROM.

If you want to go back to stock just fastboot oem lock then run the RUU. This is what I did. You can then re-unlock the bootloader and install SuperSU to reestablish root. It's pretty easy. Keep in mind, once you go to 2.20 you can not flash boot.img or radios from TWRP. You have to use adb to flash the boot.img, then boot into recovery and flash the ROM.
If you go into the Dev section, one of the first threads covers this and actually has a guide so you wouldn't have had to ask a question.

So even though I have a custom recovery (TWRP) I don't have to flash the stock recovery before I relock the bootloader?

Here. You don't need the 1.85 RUU though. Just use 2.20 and skip the manual update from AT&T.

No, it's the opposite: You can't RUU until you relock. It will fail if you try.

Oh ok...gotcha...so fastboot lock bootloader then run the ruu...great.
Like I mentioned before...I just got a little confused because people on YouTube is also flashing a stock recovery IMG before running the ruu.

RUU will restore your recovery to the stock recovery.
Just keep in mind that once you lock your bootloader you won't be able to boot your phone until you run the RUU. So make sure you're ready to go with the RUU before you fastboot oem lock.

supercid says 11111111 on 2.20 but cant unlock bootloader

very simple to fix. The fact that you got to the "ready to unlock?" screen means the unlock token works.
go into settings on the phone go to power. Turn OFF fastboot.
Power off the phone completely.
Boot to bootloader
send the unlock.bin again
this time it will stick.

Sometimes the phone can get confused about its locked state.
To fix:
-Force reboot the phone. Hold the power button for 10+ seconds until bottom lights flash and then stop.
-Boot in to bootloader
Now force the phone to lock even if you think it is locked already.
-fastboot oem lock
-fastboot flash unlocktoken Unlock_code.bin
Sending "fastboot oem lock" tends to get the phone back on the right track so it doesn't just keep rebooting in to a relocked state.
get into bootloader manually volume down + power.
Wow, so I've been under the impression that if I updated to 2.20 via the RUU that I couldn't do anything. I know my supercid is definitely 11111111. I can still unlock the bootloader if this is the situation? Root wouldn't happen though right?

unlock bootloader. Install twrp recovery. Flash the root package found here http://forum.xda-developers.com/showthread.php?t=1673935
Thanks so much gunny. One quick question. I got the bootloader unlocked without a problem. Now, twrp recovery...can I just do that through GooManager, or should I do it another way?

I think you may have to use fastboot flash recovery recovery.img because of the new limitations of the new HBOOT. It might be only for boot.imgs though
That worked rohan32 Thanks so much to both of you. Now I have an unlocked bootloader and TWRP installed. Going for root now. Thank you thank you thank you! You guys have saved me from wanting another phone!
[EDIT]Rooted as well. Again, thank you both so much!

If you stay away from the AT&T cid you will be fine.
In theory things could change but at the moment so long as you have super cid prior to RUU flashing you will be fine.
OK I just got my AT&T HOX today and from what I've read hear there is no way to root it? Since I have 2.20.502.7 710RD but if I use super cid I can flash roms?
Without root you can't get super Cid

is there a newer RUU that you can run on your device?
http://forum.xda-developers.com/showthread.php?t=2094414
The only tips that I have are
put back stock recovery on your phone if you have changed it. (you will have to unlock bootloader to do this)
relock bootloader.
OH, and one time even though usb debugging was checked on the phone, I had to uncheck it and check it again before the ruu worked.
Will relocking bootloader automatically restore stock recovery? Cause I am trying to return to stock from S-off back to S-on and I am following this guide but in the HTC One S toolkit, the recovery section doesn't have a stock recovery to flash. I can use some help with this also, I want to see if returning phone to stock will fix signal drop issues and if not I will have to return it on insurance. My biggest problems are I do not have an RUU from my carrier so could use some advice as to which one to use? here is the link for RUU's but there isn't one for Cincinnati Bell wireless.
You need S-OFF

Do you mean stoc ROM? We need your CID to get it. to find it boot to bootloader and use the following fastboot command:
fastboot getvar cid
If you are unlocked and just want a ROM to flash, all ICS and JB ROMs are compatible.

It seems that you re-locked your bootloader. Can you try to unlock it? it may help restore your phone without using an RUU. Use th following command:
fastboot oem unlock
Edit: also, how did you get to this situation? It might help solving it.

Because you are on S-ON you need to flash the boot.img of the Rom via fastboot command or
flash 4ext recovery
Enable smartflash from it
Flash the Rom

RUU doesn't regain s-on and it doesn't relock bootloader. To relock bootloader you should be running a command in fastboot that's similar to
Code:
fastboot oem relock

To ruu you need to relock bootloader only if you are s-on, if you're s-off you don't need to worry about that.
Ruu also might not set it to official, because you would have a modified boot.img, though correct me if I'm wrong.
