Mate 9 Pro, OTA after root & TWRP - Huawei Mate 9 Questions & Answers

What would be correct method to get OTA installed when current system is rooted and gave TWRP recovery? Rooted TWRP system still offers OTA updates but these can’t be installed coz update is not TWRP compatible.
Once I tried: Extracted stock recovery from update stock firmware, flashed recovery.img & recovery2.img with fastboot. Still I was not able to get update installed anymore. Ended up to install whole new firmware with FunkyHuawei.
Is there any way to update phone without losing all data and install everything again?

What happens if you get OTA on a rooted phone?

I heard the phone gets unrooted with an OTA? So what happens to the apps that need root access? They stay there and start working fine when you root again or need to be reinstalled?
Do you lose data in the process when you install OTA update on a rooted phone?
if i remember correctly , it will not have OTA with rooted phone even with stock ROM.
by root , you must have change some system file , most case, flash CWM recovery and install superuser, which will effectively fail the OTA.
You will get the ota.
it will install perfectly normal if you still have stock recovery.
if you have custom recovery manually flash the update.zip Then flash su.zip. You're now stock rooted.

I have stock recovery and I do have some third party apps installed as system apps but I havent deleted any.
I'll think unless I am one of the first to get OTA I'll prolly be too impatient to wait for it anyways and flash through CWM. But will I lose data flashing through CWM? I have flashed stock roms through stock recovery when it was allowed in GB and never lost data but I wasnt rooted back then.

Be patient, stay rooted, soon after the release I am sure there will be a stock rom that you can flash via CWM,
You won't loose data.
You can flash official updates through cwm no problem. In fact that was the only way to do it manually after 4.0.3. Stock recovery would not allow manually flashing the update zip. Would end up in a error 7.
So it was either wait for the update to be pushed to your phone or flash it manually with a custom recovery

Need help updating to Lollipop? DON'T MAKE A NEW THREAD, come here!

In an attempt to stop anyone else from making a "pls halp me" thread I decided to make one myself.
Before I go further let me reiterate the importance of regular backups. Before you do anything, make a full backup of your device in a usable state^. This serves as somewhere you can revert to if you accidentally tap something that screws everything up.
^ - If you're trying to recover from what appears to be a softbrick you should start by flashing and/or booting into recovery or fastboot at least.
Being overly excited about finally getting Lollipop (I don't check for updates often) I immediately went and installed the first update available OTA, forgetting that I had for some reason refused to update my E8 since unboxing it. I've since successfully updated from 1.09 to 2.33 (Kit Kat 4.4.2 to Lollipop 5.0) and installed the Xposed Framework, here's some issues I ran into and what I did to solve them.
PROBLEM: Update takes you to your custom recovery mode without doing anything else.
Having already rooted and installing TWRP the OTA update failed, only taking me to TWRP's recovery screen instead of performing the update.
SOLUTION: Flash the stock recovery.img extracted from the downloaded .zip update in the Downloads folder on the Internal Storage
You can probably find the OTA/RUU update .zip you need from this thread or let your E8 check and download the update .zip which you can then find in the Download folder on the Internal Storage. Transfer it to your PC and extract recovery.img from 'firmware.zip' in the update .zip file. Using fastboot, flash the extracted stock recovery image and reboot. You can now restart the update which will properly complete. Once your phone has booted back up into Lollipop and completed the update you should flash back your custom recovery of choice using fastboot.
PROBLEM: ROOT LOST AFTER UPDATE
This shouldn't be a surprise. OTA updates will unroot your device.
SOLUTION: Install SuperSU in recovery, NOT Play Store.
Download the latest SuperSU installable .zip and copy it to your phone. Boot into recovery and install.
My E8 is a single-sim M8sX but I believe these steps should work with any other variant.

Confusion with official Marshmallow upgrade for rooted stock rom

I flashed TWRP recovery and rooted my Moto g3 XT1550 but im on stock ROM itself. Now I got a OTA notification of Marshmallow update.
So, can I download the OTA & install it without unrooting or flashing stock recovery?

No! There should be no confusion here, the ONLY possible modification that can be done to your phone where you can accept a OTA update is an unlocked bootloader, NOTHING else. No Root, no TWRP, no Xposed... Your software status should show official and if the /system partition has been modified it will fail. PERIOD.
You cannot install an OTA without returning to PURE stock, not just unrooting and flashing stock recovery, you need to have an unmodified /system partition (root and then unroot is still a modified /system partition). Flash the factory image that matches your current software, then take the OTA, and flash TWRP and root again.

XT1562 upgrade to Marshmallow without losing data

Hello,
I have the Xt1562 Indian version running 5.1.1 - which I have rooted and also have TWRP as recovery.
The OTA upgrade gets downloaded but fails. I then reverted to stock recovery but still the OTA upgrade fails.
How can I upgrade to Marshmallow on this without losing my data or apps or contacts?
Thanks,
Padam
Ota fails since you're rooted. You can try TWRP flashable MM rom and dirty flash it without wiping /data
Ota is possible only if you are in stock firmware and stock recovery. Fast boot flash stock firmware and get ota or directly flash updated firmware. Githup has all stock firmware files.
Never use stock update via TWRP , you may brick your device.
During giving fast boot commands , skip fast boot erase user data will not wipe data , but while doing this I have some FC s. Otherwise backup all your files , apps data and flash firmware.

OTA doesnt work on rooted device

Hey,
i have a rooted opo and want to update with OTA.
But it just gets me into the TWRP Recovery and doesnt proceed.
I have Version:
cynogen os
12.1..1- Y0G8DAS2K1
5.1.1
what would be the easiest version?
You can't ota with modified system and you need stock recovery, quickest way would be to backup, flash the latest cyan build, otherwise unroot, flash stock recovery and try ota again.
Where can i get the newest cyan? Searched a bit but i could only find a non flashable rom.
Full wipe is ok for me.
You can get the latest version here https://cyngn.com/support you have to flash it via fastboot then reinstall TWRP and also will have to install SuperSU for root again.
