no expert here and not sure what your asking. I had rooted mine then stuck on a cust rom but had to exchange it. So I used TriangleAway to reset the count then just stuck on the official 4.0.4 and it was back to stock.. no root. Anytime you put on a stock rom it is then unrooted but the counter is still the same so I used TA and perfect.

[Q] Question on stock rom

I am selling my Tf300t and am wanting to return to 100% stock. I dont really care if the bootloader is relocked or not, id rather it be left unlocked.
I am currently running 4.0.4 build IMM76I on aokp_tf300t_build-38 with and old cwm recovery.
I have not messed with this thing in a LONG time.... I've been sifting threw some post about returning to stock.... but it all refers to some stock 404 file that points to asus website that I can no longer get.
My question is... can I just download the latest firmware off asus site "US_epaduser_10_4_2_20_UpdateLauncher" and just flash this in cwm? will this replace cwm with stock recovery? will this install a jb bootloader? can i do all this from ics with an old cwm?
Thanks for any help all...

Returning Recovery to Stock?

I'd like to turn my recovery back to stock. I'm currently running 4.2.1 stock rom with TWRP 2.5. I'd like to get the original recovery back and reverse root. It's ok if the bootloader is unlocked.
Can I just flash the original firmware and it will remove root and return the recovery to normal?
I have the TF300T-US_10_6_1_15_3-UpdateLauncher.zip file downloaded for that purpose...just want to make sure.
Any help is much appreciated - I searched but only found info on other devices.

That should work (follow this guide here), but you can't relock the firmware yet.

That's all the confirmation I needed. Thank you!

[Q] Come back to stock (P5100)

Hi
I'm coming to flash Pac ROM 4.2.2, but if I want to come back to stock, I have only to flash Rom stock (4.2.2 XEF)?
thanks

Yes, that will get you back to stock, but will not make your warranty valid. You must use TriangleAway to reset your flash counter and unroot if you want it to be completely stock and have a valid warranty.
Hope that helps. ;]

OTA Question

Unlocked U11 with unlocked bootloader, trwrp recovery and rooted stock. Have not flashed custom rom. Steps to take OTA Oreo?

Flash back to stock. Use the firmware zip it is on now to reset. You should then be able to take ota's. No need to unroot, relock etc.

Flash stock unrooted FW due twrp?
Sent from my HTC U11 using XDA Labs

Believe I have bricked my device. Flashed RUU using appropriate RUU exe from HTC. Intaller ran for @1hour with 0% process. Battery was at 93% and ran to under 30% halting process. Had to disconnect to recharge. Will call HTC to see if they can help.
Update- All cool. Battery died, charged phone boots up fine. Still on stock. Need to restore stock recovery.

If I'm not mistaken, flashing back to stock with the ruu will in affect unroot your phone. You'd still have twrp and an unlocked bootloader, but you'd have to install SuperUser or Magisk again.
Am I correct?

Flashing back to stock with the ruu will replace TWRP with stock recovery, thus making it able to take OTA.
If it's rooted or TWRP installed, it will stall at beginning of OTA process .

What if you just remove twrp and go back to the stock recovery? Would it then break root?

You could remove root of SuperSU or Magisk and then flash stock recovery over TWRP.
Haven't tried that and not sure if it would work. A rooted phone won't take OTA.
Would save restore chores if you could.

only way to take OTA is go back to stock rom by using RUU (will lost data, back to stock recovery, unroot already).
On rooted stock rom, i tried unroot and flash stock recovery by ADB but it still cant install OTA update

Flashing back to stock will unroot and flash stock recovery. If you dont do it that way you cannot update ota as the signature of the firmware is broken. You have to 're-sign' the firmware by flashing it again.
Flashing stock firmware will NOT relock or lock the bootloader. It will NOT s-on. If your bootloader is unlocked and/or s-off do not change them as there is no need.
3 essentials for the m9 are:
Stock firmware ruu.zip
S-off
Charger cable.
