I hope you can help me back up a new version of the system, or update the system backup! My phone doesn't detect system updates, I can't OTA

Hi everyone
I want to upgrade my Huawei P6 phone from B119 to Kit Kat
after reading all the post I want to do a full backup before doing anything
I have rooted my phone using an App called Root Tool
I recently installed Rom Manager and it says I have installed TWRP
but when I select "Reboot into Recovery" It reboots and I get a screen that has blue options
Android system recovery <3e>
Android system recovery utility
-- reboot system now
-- apply update from external storage
-- wipe date/factory reset
-- wipe cache partition
-- apply update from cache
But I see no option to do backups or restores
Did I miss installing something...?
Thanks
In your case you need to install custom recovery first in order to make a full nandroid bkp. The one that you go in at this moment is stock recovery and it doesn't have the option to backup. Since you have JB atm, I suggest you find the thread for JB TWRP and follow the instructions.

Thanks
I was able to install TWRP successfully and backup my phone completly
After I was able also to upgrade my phone to B132 then to B510
and now finally im at B513 with TWRP 2.8 and everything is looking good
My device OP 3 is rooted with twrp and I have received update for oxygen 3.2.4 but one note appears saying that - Root detected downloading full upgrade device will be unrooted
If I upgrade and the device unroots will I loose all the data such as apps msgs pictures videos app data contacts etc
No you won't lose any data. TWRP and xposed and root will all be gone though
Will the super su wipe out?
And why is 1.3gb heavy whereas others have got size of 26mb?
The incremental update (Small size) fails if your device is rooted, they check for changes in the /system folder. So you need the full zip (1.x GB). You have to reflash TWRP and su again. (And the other zip stuff like xposed). But no data of your apps will be removed.
U can't flash incremental updates via twrp, download the full zip and just dirty flash, wipe caches, I also wipe system for myself but I don't think u have to
Oxygen OSS 3.2.4
As 3.2.3 came out i flashed the normal OTA update with FlashFire from Play store, my twrp was gone but the update worked
After installing the Full Update on 3.2.4 none of my data was gone but i instandly reflashed supersu and xposed + wiped dalvik and cache
I made a backup of my 5x when it was running rooted/xposed 6.0.1 but then decided to update to 7.1.1 to try out the new features. But now I really miss a lot of xposed modules so I decided that I want to restore my 6.0.1 backup that I made a couple of weeks ago. So I flashed the 6.0.1 factory image from Google's developer website and was able to successfully boot into Marshmallow again. However after installing TWRP I tried restoring the backup (through USB OTG) after wiping system and cache and a doing factory reset but it pauses on "restoring system image" for a brief moment then proceeds to reboot by itself despite that it's only 27% complete. The reboot however does not go to completion and so the phone is stuck in a bootloop. I'm really not sure where the problem is here. Is it TWRP? Or the backup file? What can I do?
Which version of TWRP have you used? By any chance the backup also contained EFS?

I used version 3.0.2-2.
And isn't EFS supposed to be backed up anyway? I just checked the backup folder and it contains 4 files that begin with "efs". Should I delete those and try again?
Format everything from TWRP except internal storage. Restore your backup without EFS. Next time you want to come back to another version just be sure that you also backup the vendor or you flash the vendor corresponding to the version you're restoring beforehand.

I made the backup while I was running 6.0.1 and I flashed the 6.0.1 factory image so they both should have the same vendor image.
I also tried wiping everything except for internal storage and I unchecked "EFS" when restoring the backup but the same problem still persists, the phone automatically reboots itself before the restoring is complete and gets stuck in a bootloop. I'm not sure where the problem is at this point. I guess I'll just have to start from scratch again
haven't updated my phone in quite a while now, and was wondering if there is a method to update to latest OOS without having to perform a backup-->clean flash-->restore.
obviously the backup should stay, is it possible to update without clearing data?
what about oxygen updater app?
thanks

If you are changing Android version, it is better to clean flash. Clean flash involves wiping System, Data, Dalvik and Cache. Internal Storage where your photos and other files are stored need not be wiped. That said, it is prudent to have a backup of the photos and other files stored on your PC/Laptop since you never know whether ultimately you end up wiping Internal Storage also.
Obviously, you will lose root (and TWRP) which you have flash again. For root, Magisk is better than SuperSU on Oreo.
I have no experience with the Updater app.
Need some help
Today I check if there was new updates for my system lineage 16. There was two new updates, on of 26-04 and another of 27-04. After choosing to update lineage 16 to the last version of 27-04 using the updater in settings, the system doesn't boot anymore and goes always to recovery twrp 3.2.3.
Tried to wipe dalvick and cache but with no effect.
Unfortunately I didn't do a backup before updating.
I noticed when the system was updating it simply rebooted itself without showing any information of update installed successfully.
What can I do to go back to previous version? Is there a way to reverse the update without installing again the ROM and lose my data and installed apps?
Before the update everything was working well.
The device is a Pocophone.
Thanks.
