[Q] (Q)How to install the official 4.2.2 update with root

Ive downloaded the 4.2.2 official update on my HTC one,When I click install now it goes into TWRP and doesnt allow me to update.
Do I need to flash the custom recovery to update?
and if so will I need to flash TWRP later after upgrading or is there another way?
Can I locate the update file on TWRP and install it ?

Search for the stock recovery, download it, flash it with the phone in fsstboot mode.
fastboot flash recovery recoveryfilename
This should be documented in the returning to stock sticky thread. Or one of the other many similar questions here.

after you are done with the OTA, .... Unlock the bootloader again, and then whichever recovery you like you can go for it..

U can grab the rollback package from my signature, there is pdf file with instructions on how to use it. inside the zip file.
You have to use the same method for the mm firmware you like to rollback to.

You need a stock recovery to flash stock firmware...
I overflashed only the kernel, so the phone didn't boot, so i tried to find a kernel to flash back, so the phone is booting again, the only one worked was that custom one, but not stable.
So I'm trying to find another better working kernel to flash, or an alternative way to reset my phone, but my recoverys aren't working.

I'm afraid you'll need to reflash your firmware if you don't have the stock boot.img

Firmware from firmware finder website.
Flssh via dload or extract the boot.img from update.app file via Huawei extractor and flash via fastboot.
Also i posted a guide for rooting see if you can use that twrp and SuperSU.

Currently you have TWRP installed which is not stock recovery so dload method doesnt work.
Inorder to dload method work you need to have stock recovery.
Follow the procedure.
1. Take a nandroid back of the current system,boot, and other partitions, make sure the backup is not corrupt.
2.Now wipe all partitions through TWRP.
3.Now extract stock recovery.img from update.app of the version you like to downgrade using update extractor tool.
4.Now flash the the stock recovery.img using adb.
5.Now place the update.app in root dload folder of SD card and use there buttons to boot the system.
6.Wait the process to complete and you will have downgraded version.
Note the above method will work but proceed with caution.

Hi, I did not get the first option right
What is the second option wipe cashe-wipe reset factory,.. ?
If i did it
Option III extracted recovery.img file
I flashed through the adb and then placed the update.app file in the dload folder on the memory card and using the three button method, I did not accidentally happen, and the phone will remain in the logos.
2 questions asking:
1. Which version of twrp should I install?
2. Is the Android 6 CASTOMRAM available for my device
