Hello, I have a question concerning OTA updates. Should I perform a recovery before installing the OTA Update? Is my data wiped during the process? And do I need to flash a new boot.img?

But having a recent nandroid backup could be usefull.
Hi,
I've a Nexus 5X since few days. I've unlocked bootloader, installed TWRP and rooted.
1) Update
When there will be an update, what can I do?
OTA doesn't work, it is?
I must download the firmware and..? What do I flash (I don't want to lose user data).
Then.. Must I reroot my device or reflash TWRP?
2) Decrypt
Do you recommended to decrypt the Nexus 5X?
How can I do this with/without lose data?
Can I update the o.s. also if it is decrypted?
What? What are you trying to do?

1) Read my guide (section 9) for your first question:
http://forum.xda-developers.com/showthread.php?t=3206930
If installing factory images, install your mods before boot. Also, you need to root or install a modified boot.img for stock 7.0 to keep TWRP installed each OTA.
2) Can't be done. You must format your phone aka wipe internal storage to remove encryption. Then install a modified boot.img or custom kernel to keep encryption removed from the phone. Installing the stock boot.img from any OTA will automatically encrypt when you start up. It's not worth the effort it this sounds confusing to you.

Hello all-
I have looked everywhere for clarification on this to no avail. I am currently UN-rooted, Unlocked Bootloader & TWRP (OOS 4.0.3, 12/1/16 Android Security patch). Can I take the OTA for OOS 4.1.3 or will that make me lose TWRP? I know there are instances when you can take the OTA and where you have to flash the entire ROM but I can't locate the differences and which route I need to take? Please advise if you know this answer.
Thank you!
I'm not sure, but, you can just flash the ota in twrp and make sure to flash the twrp img after flashing the ota. And, always make a twrp backup
AFAIK you need stock recovery for OTA to work (not 100% sure).
If downloading whole 1.4GB ROM is not a big issue, it's safer to dirty flash the whole ROM. Otherwise you could flash back stock recovery, install small OTA, then flash TWRP again. A bit more work, but less downloading.

Let me make it clear, the full rom flash is a better option and you can do so from twrp. You would not loose twrp after the flash and need not flash the recovery again. SuperSU/Magisk flash is optional after the ROM flash. I see that you are running 3.0.4-1 which is a 7.1.1 compatible TWRP so there is no need to worry of any data loss. TWRP is also able to flash the OTA's provided you have not made any changes to your system partition and have remained unrooted.
You can come to General / OOS thread and ask there for further understanding :fingers-crossed:
You can flash OTA as long as your kernel is on default, what I mean is stock/untouched which is basically same situation as yours since youre unrooted. ? So yes you can flash OTA no need for full flash
If me, i like waiting full ROM zip release and do clean install.
Sometimes, flash OTA getting error (cause root, bla bla bla hahaha )
Yeah, it could be lazy gonna install back all apps at least you backup it
My advice, if you update same Android version, no problem to do a dirty flash (same ROM like LOS 14 to LOS 14, but if different ROM, i suggest better do clean install)
But if different version, mean 7.0 to 7.1.1, better clean install (dirty also no problem, but wonder in future got problem)
But hey, different people, different way right? This just my 2cent
It is my understanding that when moving from whole version number changes (6 to 7, 7 to 8) etc that a clean install is definitely way to go but even from 7.0 to 7.1? Also when you download the OTA, is the file saved somewhere so you can then locate it in TWRP for flashing? I don't want to allow the system to install the ota automatically correct?

It is best to clean flash if you've major upgrade like 6->7 or 7>8 something like that but if as your question you're still on marshmallow so you can flash OTA zip through twrp and make sure after OTA you've to flash twrp again to maintain it. If the system shows OTA it can't flash it via open recovery on twrp, you must have stock recovery to do it.

I have bootloader unlocked on my pixel 2 xl. On android 9 with magisk.
I was wondering if I could flash android 8.1 and keep my user date (apps, photos, settings and everything) in take and just downgrade? Is that possible? Or do I have to do a full wipe and flash 8.1 and install everything?

You will have to do a clean install and wipe. No other way around it.

Ah okay. Should made a twrp backup. Oh well. Thanks.
I inadvertently updated to A12.
I'm not sure I like it and I'm thinking about downgrading back to OOS 11.
I know it will wipe my phone, but will I also lose root and need to go through the rooting process again?
I still have the last full OOS 11 update downloaded on my phone storage if it makes things easier
Alternatively, right now I'm booting on slot B (after going to 12) if I force boot to slot A will I be on 11?
U will be fully stock after downgrade
