Updating oxygen os without losing TWRP possible ?

Hello,
i am using oxygen os 3.1 with TWRP recovery. No root no modifications other than TWRP.
Is it possible to update without factory reset to the latest oxygen os without losing my custom recovery TWRP?
I read about signed flash able zips - but i am not sure on how to proceed.
Guidance is appreciated !
Thank You

You want to upgrade to latest 3.5.5 ? You'll have to wait until signed flashable zip for 3.5.5 is made. For now 3.1.0 is the latest flashable zip.
Check this thread -> http://forum.xda-developers.com/oneplus-2/general/rom-mirrors-official-oxygen-os-roms-ota-t3209863

Thank you,
so i will wait for the full signed flashable zip.
still - my questions remain - i do not completely understand this :
Note: Since OTA incremental update zips will fail on rooted devices or devices with modifications to system files, it's not possible to use these to update without reverting back to completely stock, unrooted first.
To update you must either wait for the new, full, signed flashable zip to appear (usually a few weeks after the OTA update) or use the following workaround:
Boot into TWRP recovery
Flash the latest full signed flashable zip
Flash the new OTA incremental update zip
Flash the SuperSU zip
Reboot
Is it possible with the full signed flashable zip to keep twrp and my settings ?
Thank You

As it says you can't use incremental update zips if you're rooted or has a modified system. You can either Flash the latest full signed flashable zip & then Flash the new OTA incremental update zip (without rooting) OR just wait for the Full signed flashable zip & then flash it(whether you're rooted or not). As for now neither "Incremental" nor "full" signed zip exists for 3.5.5.
And Yes. You won't lose TWRP.
To understand more about "Incremental" & "Full" update packages, read this -> https://source.android.com/devices/tech/ota/tools.html

you can flash full rom zip and without restarting flash twrp image in twrp itself, its kinda tricky but it works

3.5.5 Full Signed Flashable Zip's now available. Check the thread I sent before.

I was on 3.1.0 with Hybrid recovery and root before the OTA for 3.5.5 came through. It installed itself via the ota (1.2gb) and when it was done I was back on default recovery and no root...which i fixed in few minutes..So I am now on the latest OS 3.5.5 with Hybrid Recovery and Root..everything is perfect! No network drops so far e.t.c
Edit: I didn't have to unroot for the OTA to work..It just did. Also didn't lost any data. all apps +data still intact

Thank You B!Gguy.
Signed flashable worked flawless

OTA Update Root

Hi everyone ! I'm here because I want to do an OTA update. But i'm root and I have a custom TWRP and the ota file. If I flash it from twrp it will be working ? (Doesn't matter if I need to reroot and reflash twrp) Thanks !

you need to extract stock recovery from you current fw, and i am not sure if even then ota will work, I think you need full rom and flash it from huawei recovery

Install Custom B602 rom by persona, you won't regrete

Moto X Play - Can I return to stock with nandroid & perform OTA?

Hi folks,
I am using Lineage 14.1 for a while. So, I want to go back to stock once Lenovo released Nougat.
I have a Nandroid backup of my old Marshmalow stock rom made with TWRP.
My question is: If I restore the nandroid backup, can I make the OTA update or will I brick my phone?
Hope someone can help
Thanks

You backup probably doesn't contain the valid recovery for OTA update (because, to make your backup, you need to replace the official recovery with TWRP). So, once you restore your backup, you must also flash the original recovery with fastboot.

Check if System Status is still official in the boot loader. If its 'Official' you can flash stock recovery after restoring your backup and then can install OTA update. If status is 'Modified' you have to flash the whole OS with fastboot commands to get OTA. But dont downgrade to Marshmallow after getting Official Nougat, your will hard brick you mobile and there is no way to ressurect it as of now!

can I flash ota update in twrp?

I received ota update notification. I downloaded the zip, it is npn25-37, currently my phone is on npn25-33. I have magisk root and twrp. I wonder if I can flash the ota update zip in twrp? Thanks

It will not work, OTAs require the stock recovery. Since you hace TWRP there is also a chance that it might have mounted your system before, so your system image isn't vanilla anymore and the OTA will fail to apply. First try flashing stock recovery from here (search for the version you currently have, which is -33) https://forum.xda-developers.com/g5-plus/how-to/firmwares-moto-g5-plus-t3593160 and then apply the ota. Since the firmware you're on is quite outdated, you'll probably have a couple more OTAs on the way.
Now if that doesn't work, you'll need to back up everything you have (apps and data) and flash system, oem and recovery, and then apply the ota updates, then restore your data.

Xiaomi Mi 9T Pro EU ROM - How To Install OTA Updates Through TWRP?

Hi so recently today I was able to successfully flash my stock ROM from Global 11.0.3 to Europe 11.2 (20.3.5).
All works, I have a new and version specific TWRP recovery which solves the decryption issue and such.
Only problem though is I can't seem to update my ROM from the latest Europe 11.2 (20.3.12). I am aware that we cannot install OTA updates like we normally would because we are on a custom recovery. I tried flashing it from the 'choose update package' where it brought me to the TWRP and executed OpenScript to flash, and also tried flashing from TWRP itself. No luck. Bootloop into Redmi Logo and TWRP recovery, so I end up restoring the working Eu version.
An updated tutorial on how to install OTA roms on custom recoveries would really be appreciated, thanks!

IMO, if you want to update by "choose update package'", you should be also on stock recovery, not TWRP (but I'm not using eu weekly ROMs)

You use "xiaomi.eu" custom ROM ; saying "Europe" could be confused with Official EEA ROM. ^^
You can use the Updater app in this custom ROM and update/flash ROM updates.
You don't say if you use Magisk or not. Magisk could be the raison of your issue after flashing new ROM version.
