Hi everyone
I recently updated to B609 and (as expected) my phone was un-rooted.
I decided it would be better for me to just install a ROM instead of waiting for a new way to ROOT every time a new OTA comes out. (I have seen some very interesting ones that include Xposed)
This would be the first time i install a ROM on one of my phones but i do know how to use custom recovery's and i will always keep a copy of a backup close so i can flash back when something goes wrong.
A problem i have with starting all of this: I can't seem to find a way to unlock the Bootloader on my phone.
I have looked online but i always get links for older versions/other phones/German stuff.
Second problem: The recovery. As far as i understand, there is no working TWRP for EMUI3.0. BUT there should be a working CMW recovery. Should i go fot CMW?
Third problem: Which ROM? There are 3 that grabbed my attention. Se7en-Rom (But it seems like it hasn't been updated in a while), My-RoM (which seems the most interesting for me at the moment) and Miui (which i just found out about). Which should i go with or should i use another one? I can already say that i want my phone Rooted and Xposed is something i would love to have back (since i used to have it on my previous phone).
Any advice and help would be appreciated

I have a P7-L10 with B609. I was able to successfully root it with RootGenius. When you root it, the bootloader is unlocked at the same time. As far as I can tell, the root is 100%. As for CWM, you can get it from here:
http://forum.xda-developers.com/ascend-p7/development/mods-tweaks-kernels-recoverys-emui-2-3-t2966670
TWRP doesn't work with B609/emui3.0.
My L10 has faulty flash memory and won't accept a custom recovery, so I can't test CWM or any custom ROMs. Perhaps others can advise. Good luck!

RootGenius was the first thing i tried. It went up to 66% then i got an error but that was a fully Chinese version.
I just tried it again with the one i found by using Google and it goes up to 72%, then tells me that the root has failed.
Which version did you use?
This is what I used and it worked fine (root genius): http://forum.xda-developers.com/showthread.php?t=2789337
As for bootloader, as far as I know from, starting with firmware 133 (Emui 2.3) all devices have unlocked bootloader
CWM is the only custom recovery for the moment;
Did not try any custom ROM (I'm happy with stock ROM for the moment).
Cheers

That's the first one i tried out. The first few times it ended in an Error. I tried it again today and when my phone reboots during the process, RootGenius loses contact with my phone.
And there is a bootloader-ish thing, but the only options i have is reboot, factory reset and cache wipe.

Hmmm, strange problem. Assuming you have the latest version of HiSuite installed and your drivers are current, all I can suggest is trying again with RootGenius (I used version 1.8.7) with your firewall and antivirus disabled or perhaps trying with Vroot. If you do decide to try Vroot it probably won't work unless you disable your firewall and antivirus.

I disabled my firewall and antivirus and gave RootGenius another try. Normally it goes up to 71% and gives me the error. Now it went to 71%, rebooted and then it gave me the error. The weird part is that right before i get the error, it says the installation is complete.
Moved on to Vroot (which is called Iroot now apparently) . It took a while longer but it wasn't able to do it either.

Get in bootloader mode, if your bootloader is unlocked, it will be written and highlighted with red color. I will point out again, starting with firmware B133 (Emui 2.3) all bootloaders for L10 version (I don't know for Chinese versions) are unlocked
Cheers.
update to b615 and flash or just flash this >> http://forum.xda-developers.com/ascend-p7/development/b615-unlocked-boot-img-t3050926 and use rootgenius remove inmutable etc...

You were right! (not that i every doubted you). I found the problem i had: For some reason, i couldn't boot in bootloader trough my phone BUT i was able to do it with 'adb reboot bootloader'. After making some idiotic mistakes and having to re-flash the stock ROM, I finally was able to install My-RoM v3.3, its rooted, i have Xposed so i am happy
So thank everyone for the help!

Hi,
First post on here. I have bought the SM-N9200 in China after my Z3 screen broke for the second time. I live here (china) at the moment but did not realise that you would be unable to install google play services and therefore google play on the phone. I have a fair few apps purchased on GP and would like them on my phone.
I have read that I would need to have root access prior to being able to install GP but I am running into problems. I have never rooted before even though I was aware of the process etc but have so far been unsuccessful using kingoroot and I cannot seem to find a root method for the Chinese n9200. I saw today that the spaceX kernel supports N9200 so I thought that I would flash twrp with odin and then consider flashing spaceX. However when I try and flash TWRP it fails and the phone displays a message in Chinese that I cannot read as my Chinese is not that great still.
I am not in a hurry to install a custom rom at the moment and mainly just want to be able to get my apps. Can anyone suggest a method? is it possible to install HK Rom onto Chinese n9200 for example?
Many thanks

To flash in Odin you need to enable OEM unlock in Developer Settings.
I tried installing Chinese on HK and it failed (Cache.img)
OEM unlock and USB debugging are on. Odin was run as Admin.
If you try flashing the wrong TWRP (i.e not for your phone) will it fail or will it still flash. I was trying to TWRP for the DUOS version which i am assuming is my phone as DUOS is the dual sim variant?
I will get a chinese friend to tell me what the message is and take a photo of what happens.
Essentially i boot into DL mode and then attempt to flash when the bar fills up the odin still says recovery but the screen on the phone gives me warning (triangle with exclamation) and some information including a the web address for samsung.com/cn
I can help with that Chinese message. There are some problems for you to use GP in China. First, you can use Odin to install HK (TGY) Rom( remember to backup before u do so). After you install HK Rom, you need to connect to a VPN and then go to Google settings.
Hope these info would help you.
Possible solution found in another thread. it seems that the bootloader is locked on some devices and therefore you cannot flash anything.
http://forum.xda-developers.com/not...ote-5-root-t3214234/post63073600#post63073600
One question. What would be the difference between the HK and Chinese versions of N9200 other than some restrictions. Is it safe to use guides like the one linked for a chinese version?

TGY is the name for HK ROM. You can find it on samsung-updates. Both Mainland and HK variant share the same specs, which is N9200.
SUCCESS!
So after much stress I have a rooted, TWRP'd, Romd N9200 Chinese version. I say stressed as I had some problems when i flashed TWRP in that it would not let me boot back into the stock rom. this leads me to one unanswered question. When flashing TWRP with ODIN is it a requirement to flash a new rom?? I say this as I had the following problem. When I first flashed twrp the phone booted into stock so I rebooted into recovery only to find stock recovery and no twrp. I checked that the KNOX counter had been tripped (it had) but I was confused. I read on twrp website that on some devices if you let phone reboot into stock after twrp flash rom it overwrites custom recovery. I eventually flashed twrp and quickly pressed key combination for recovery and I had twrp but then I could not boot into stock rom (bootloop).
After spending the afternoon in a state of panic I reflashed the stock rom from Sammobile and was back in business. crisis over and a bit of confidence gained.
I am now using SpaceX kernel following this thread:
http://forum.xda-developers.com/note5/development/kernel-spacex-pure-edition-stock-t3236317
so far no problems so thanks to @Manh_IT
Here is my step by step if anyone finds themselves in same position:
1) unlock OEM and USB Debugging and backup everything using SmartSwitch (this replaced Kies I believe)
2)download CROM apk from Samsung appstore to unlock bootloader
3)Download SpaceX, SuperSU.apk, Gapps and twrp and place all except twrp onto phone memory
4)Flash TWRP with ODIN and reboot into recovery using method described above if need be.
5)factory reset in twrp
6)flash SpaceX and Gapps
7)reboot system and install SuperSU
I hope this helps someone.:good:
Anyone rooted in n9200 with latest OKA firmware?
actually you don't need to root your device...
just make sure OEM unlocked and find a HK version stock ROM and install it with Odin

well if you use N9200(CN)...you can follow the steps to get gapps
Once you use Crom.apk, you lose your warranty , so DON'T use CROM to unlock the phone
Make sure OEM unlocked
Reset to factory in case of some issues
Turn off the phone
Take the sim out of the phone
Get into download mode
Plug to PC and use ODIN to flash the HK stock ROM.
gapps will be install , no root, and you wont lose you warranty , but the battery saving is not as good as CN version.
I have gapps on my note 5 n9200

Hi great to heard that you have managed to resolved this issue. I have the same problem ( I bought my Note 5 in Beijing recently), so please can you explain what I need to do? I can do point 1 & 2 but stuck on point 3 and the rest. Where do I get all these files from?

Hello there!
Following these steps, you'll be able to root your freshly marshmallowed P8 Lite.
The method was tested by several other users, with not just this model.
Requirements:
Huawei P8 Lite with the Chinese 6.0 Firmware
Unlocked bootloader
TWRP Recovery (Kirin Chipset)
Do you have everything above?
Good, here are the steps:
Go to THIS post, and download the attachment of it. (BETA-SuperSU-v2.67-SYSTEMMODE.zip)
Put this zip on your SD Card.
Boot into recovery and flash it.
That is all what you need to do.
Credits goes to: aufarxda for making the working zip, zirangua for trying and successfully rooting our device with this, and of course Chainfire for making rooting phones possible and easy.
Note:
If you tried with the official zips from Chainfire's thread, you should rooted your phone as well, but the root was lost after a few reboots.
At least it was like that for me.
The reason for this, Chainfire introduced a new way of rooting the phone, which called "systemless" root. It means, no modification is made to your /system partition, only to your boot image.
The install script of this zip checks for compatibility to do "systemless" root, and if it can do that, it'll do that.
However, with our device, something must be messed up with the boot image, because it seems to be resetting after few (or the first) reboots.
The downloaded zip was modified in a way, that the script only root your phone via the old method, modifying your /system partition.
The whole point to have a "systemless" root is not rerooting after every update, or system reset, however, it seems like it's not working well with our phone, so only the old method remains.

I'm wonderin too. But this is not only difference in Chinese ROM. On B524 not feature like Touch Plus, Smart Care, Mobile data traffic counter, HiCloud and many others
So my opinion is Chinese firmware is much better that European. For that I change my ALE-L21 to ALE-UL00

Hi,
I rooted my device over the weekend, and it became soft bricked a few days after - that is now resolved.
I recovered my Huawei P9 using TWRP to b136 rom - but now its not allowing me to use the Themes built in (wont allow me to amend icons, lockscreen display, home wallpaper etc).
I am not 100% sure that I have used the correct ROM - is there anybody that has a Huawei P9, who has rooted successfully and using a good ROM that supports all?
Also worth adding that my device will show the intial "Device is not secure" screen when booting - but when running a Root Checker app, it states it is no longer rooted.
Any advice would be great!
I'm on rooted B136 and never had issues with themes. Maybe you should go back to stock recovery and reinstall B136?
The "Device not secure" message has nothing to do with phone being rooted or not but with bootloader being unlocked.

That makes sense about the bootloader. Thanks

Hi
I have installed many of the Android 7.0 ROMS for Shamu and all of them have this annoying problem:
When I dial out I cannot hear the ring or the other person.
When I receive a call I don't often hear the other person but they may hear me.
Yes I've installed the N6 boot loader and radio and do not load any other mods, custom kernels.
I just can't figure this out. Any ideas? Is there a Android 7.0 firmware that I need to install to prepare my Shamu for Android 7?
Thanks
Aussie
I had this same problem, I had to re flash stock 7.0 and the problem was gone. No idea what caused it

Did flashing stock 7.0 re-lock bootloader? Were you able to unlock the phone?
Thanks

Flashing stock does not relock the bootloader.
Didn't work
Ok I flashed stock 7.0 using Wugfresh's tool.
But still when I use the phone I can't hear who is on the other end.
Really odd!
Anyone have any suggestions?
Thanks
Aussie
I'm having the same issue on a stock Nougat phone as well. The problem appeared a few days ago out of the blue. The only band aid fix I've found is the sound about app and force assigned the mic and earpiece functions.
Sadly, this doesn't address the main issue in the first place.
none
Why are you using Wugfresh? Plug the phone in the computer and when it communicates with the phone tap the menu bar that says it's charging, when you open that tick allow files/folders, the second option. Then put your files on the root of internal storage, wipe the entire system then flash your rom, you don't need Wugfresh.
If you lose your data who cares, just set the phone up again and you should be good to go, this is much more dependable as I use to use Wugfresh, you do know how to get into recovery and install that way? You will want to do a full wipe, then flash

I didn't realize there was a thread on this already.
I'm using Pure Nexus and the other end would go silent for about 5 seconds and then come back...so that's a bit different than what you guys are experiencing.

have you tried reflashing your radio? Maybe try flashing a MM radio as well
Just wanted to chime in, I think this is actually more of a VoLTE/HD issue. It happens to my N6 that's still on MM. Sometimes the dialtone/ring is there, other times it's not. Would love to know of there's a fix!
Found a fix..
Hello all.
I found a fix to Shamu+Nougat ROM problem when I am called I do not hear the other person and vice versa.
To install Factory Nougat from Google: https://developers.google.com/android/nexus/images
FIRST backup your phone (contacts, files, pics, movies etc) as this will totally erase EVERYTHING!
When you are on the Factory Images for Nexus Devices page click "backed up to your Google Account" then go click 'back' on your browser and click on 'Acknowledge' to see the list of Factory Nougat ROMS for Shamu come up on the right.
Download the Android 7.0 Factory ROM for Shamu/Nexus 6.
Do not flash this stock ROM using Wugfresh's tool. Instead follow precisely the 'Flashing Instructions' on the page https://developers.google.com/android/nexus/images. Allow the phone to reboot and fully set up. Restart the phone again.
Then use Wugfresh to Root the phone and also to install custom recovery (I already have unlocked bootloader).
Now, nothing against Wugfresh Tool (I do not know why the flashing method above works better) as Wugfresh has saved my phone many times.. Its just that Googles recommended flashing instructions worked best.
Now I use the phone and not only do I hear the caller and they hear me I have much better reception (Australia). Yes I did previously flash latest radio but the above method seemed to improve my Shamu 100%.
What I have not done yet is flash a custom ROM in case the problem re-appears. But my phone is rooted and unlocked so I can install other mods that work with Nougat.
Hope this works for you.
Cheers
Aussie
Another Fix Part 2
Hi
I stumbled on another method that has seemed to work:
Ensure you have unlocked bootloader.
Flash Tupacs Android 6.0 MOB31H ROM from http://forum.xda-developers.com/nexus-6/development/rom-rooted-deoxeded-fast-stable-t3252922
(*Note I used his MOB31E Android 6.0 ROM so I am presuming current MOB31H will work).
Credit to this ROM goes to tupac4u as I am not a Developer.
I then flashed SuperUser but did not flash a custom kernel.
Setup the ROM as usual.
Selected Settings - About Phone - System updates and let the phone install the Android 7 OTA update. Be aware its a 878Mb download.
Let the update download and fully install. I had TWRP recovery and the update still installed fine.
After installation fully completed I enabled Developer Options and USB Debugging.
Then using WugFresh's excellent tool http://forum.xda-developers.com/nexus-6/development/toolkit-wugs-nexus-root-toolkit-v1-9-8-t2947452 I applied Root and Custom Recovery.
I also flashed Radio 5.39R which I found works best.
Now my phone works very well and (for now) now I can hear the caller and they can hear me.
Cheers
Aussie

Has there been a listed fix for people who haven't rooted their nexus?
Hi guys, like the title says. I'd like to flash OK Pie onto my old but still working P9 but after so, so much time i have forgotten everything I did to my phone to get to where I currently am. I've been searching for specifics to my situation but the guide to go from EMUI 8 to OK Pie is complicated enough as it is. If I have to factor in the "back to stock" procedure etc I think my brain would explode xD
So I'm looking for any links, guides, personal help or WHATEVER may help me at least get to chinese OREO 9I think I'm capable of taking it from there)
My current setup:
EVA-L09
Build number: EVA-L09C432B378
EMUI version: 5.0
Android: 7.0
My phone is from Latin America, So IIRC I unbranded it, changed it to cust 432 and flashed the latest (stock) firmware which at the time was B378.
I also have TWRP (the latest one) installed. If I got it right, I THINK I need to go back to stock recovery, flash the latest FW and go to Chinese OREO from there before trying to flash OK Pie, right?
Could somebody please be so kind as to either help me or at least point me to a thread/guide made for idiots such as myself xD that can walk me through the steps of going from my FW to stock recovery and stock latest FW?
I'll manage to get to oreo and custom after that.
I appreciate your help in advance.
Thanks.
EDIT: Forgot to mention that yes. I kept my unlock code so thats no problem
Thanks again!

General link for Open Kirin ROMs

P9 thread for OK ROMs (under the P9 ROMs, Kernels... collection)
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806
In short:
1) You must rebrand and update your L09c432 Nougat to AL10c00 Oreo, it is PRECISELY explained in the OP posts (mainly the post #2, but read #1 - #5 to get better picture) in the corresponding thread:
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
2) Once you will be on EVA-AL10c00b540 Oreo, you have to follow the OK installation guide from the first link.
You will have to install OK Omni Pie for Android 8, not for Android 9 (there is no stock Pie for P9)
If you search for Pie in the given two XDA threads (Search box at top- right on any XDA page), you will find that many people have undergone (and some returned back from OK Pie to stock Oreo) with no problems - but it is important to carefully follow the guides, first for rebranding and installing the Chinese stock Oreo, then to install OK ROM EXACTLY as described on their site (common guide for all OK ROMs and for all Huawei phones when already updated to the stock Oreo)

Hi, thanks for replying. I'm aware of the PROCEDURE not so sure about the "how to".
Thats why I posted. Your post basically told me what I already knew (and talked about in my post)
What I'm looking for is help going from my current TWRP/STOCK/ROOTED FW. Back to full stock so I can start updating the ORIGINAL FW. I can't find any info on how to go back to stock recovery for instance. Do I need a specific recovery for the FW I'm running? Is it generic? Where do I find it? How do I flash it? Where do I get the stock firmware? (Huawei firmaware finder?) Which one do I flash? Does flashing the stock firmware automatically flashes the stock recovery? Things like that. I appreciate you trying to help but I already read and knew the things you linked to. My issue is, like I said: going back to stock before I can follow any guide to go up to oreo.
Thanks anyway!

If rooted by Magisk, there is Uninstall option in Magisk Manager, it will unroot.
Similarly SuperSU had an Unroot/Unistall option.
In both cases you can flaslh back the stock Boot partition but it is cleaner to unroot by using their Uninstall options.
From TWRP or Fastboot you have to flash stock Recovery (corresponding to your current stock Nougat firmware) to revert back from TWRP
Generally, if you download from FirmwareFinder update.zip corresponding to your current stock Nougat (must be from FullOTA-MF or FullOTA-MF-PV), unzip, then by using Huawei Update Extractor, you can extract Boot.img and Recovery.img that you can flash then from Fastboot or from TWRP to go back to stock Boot and to stock Recovery
Once you go back to stock Boot and Recovery, you can boot to eRecovery (switch off, connect to charger, keep pressing Vol+ and boot by Pow) and choose Download latest firmware and recovery
----
But in fact, since you already have TWRP, use the HWOTA method from this post to update to c432b504 or b505:
https://forum.xda-developers.com/showpost.php?p=75787151&postcount=2
You can do the same with HWOTA7 from the corresponding thread I gave you (before you will go to rebrand to AL10c00b399).
In both cases, you have to download three update*.zip files for eg L09c432b504 (must be FullOTA-MF), rename one or two of them as described in the OP posts (be careful, some people have Windows 10 that hides zip extension and they wrongly rename files to have double zip extension and then HWOTA/HWOTA7 scripts cannot find the file and fail to flash resulting with half-brick), put them to DLOAD file on the SD card and follow the guides

Thank you. Thats exactly what I was looking for. I really appreciateyour help.
Btw, no one should have the "hide extensions for known file types" checkbox marked...
Edit: Should I flash the same FW version Im currently using and then update regularly? To prevent any issues? (Cause i noticed there are some rules as to the version jumps that can be made flashing like this...

It must be the same model and cust, c432, but safer if you also apply the same build number (b387 ?)
Once you are back on stock you should start receiving OTA updates (have WiFi and a valid SIM card). Give it some time but check also manually from Settings / System updates.
As mentioned in my previous post, you can also use eRecovery / Install latest fw and recovery (if OTA coming slow), and there is a similar option in HiSuite. You will probably not need to use HWOTA or HWOTA7 to jump from clean stock b386 up to b50x

Hi again. First of all I would like to thank you agaib for your help. You made the process so much sinpler and quixk for me and I do apprexiate it.
Second, I updated to the latest "original" fw for my c432 phone OTA but then had to modify the HWOTA7 procesa so I could dl and install the latest/latest fw (because it wouldnt even register when searching for it) I used huawei fw finder to verify it and dl.
After that I went to chinese Oreo, flashed the network fixes and installed a TINY OTA update which fixed some sexurity issues apparently (thankfully it went Ok cause I THINK flashing OTA in a "converted" phone is a big nono?)
Anyways, I ended up on omni pie (the latest beta whixh is 5.2 I believe) as going AOSP was the whole point of this endeavor.
So far I'm LOVING it. Its such a refreshing thing not having to deal with all the bs OEMs bake into their roms... But Im experiencing a couple of issues as well. Not sure if its the rom, my phone or the android version (particularly my issue with battery life since I was having issues with the duration way before I updates, actually that was one of my motivations for updating since I read that pie had better battery management)
Anyway, my issues are as follow. Hope you can help (once again)
Battery life SUCKS (like really, it went from bad to terrible... Not sure if stock oreo would make it better, or perhaps omni pie needs some optimizations?)
The camera (huawei one, not sure about the aosp) has issues. Multiple issues. The biggest one being that if I try to go from back to front camera the app locks in a black screen and I have to go into the app, delete data, reboot the phone and relaunch it (and that doesnt fix it everytime)
The last issue is with pop messages from apps and/or settings. Sometimes, when installing and app and/or changing aome setting a white popup shows up with ONLY an OK option. I cant read anything on the popup. Everything is white. Not sure if its an issue with the theme (I changed from default to "hell" or something like that) but it is VERY annoying not knowing what youre agreeing to.
Last but not least I have a question about the stock rexovery, factory reset and flashing new versions of omni (if and wheb they come out)
In one of the steps for flashing omni the guide asks to perfomr a factory reset from the stock rom. Thing is, it doesnt work. I mean, when I confirm the factory reset the process starts and approximately at 15% an exclamation sign appears and the process percentage stops working. I can reboot the system and everything works fine (using the phone to post this actually) but Im left with that feeling of not knowing why something failed... You know what I mean? Is that nornal?(the failure to factory reset, not the feeling ) also, does factory wiping the phone removes root access? Or does it only renove magisk manager?
Also, if I ever wabt to update the rom (not change it mind you, but flash the next beta or stable or whatever they come up with) do I need to flash the stock recovery again? (Currently rooted with magisk) or is it a separate partition? (Sinxe I had to modify the ramdisk and not flash a custom recovery) also, will I need to do the whoooole thing again? (Backup everything, restore tk factory etc etc) or is it just like with lineage for exanple where you could flash and updatr and keep your data untouched?
Thanks for EVERYTHING my friend. And I hope you can answer my questions (particularly the ones about battery life and thebfactory reset issue since Im planning on doing one last factory reset before settling with the rom. Just waiting for my new micro sd. The one that will stay in the phone)
Sorry for the typos. Writing this huge post on a phone is a PITA.

This small OTA bringing Patch02 over b540 installs even over TWRP (but that was not the case for OTA from eg b535 to b540)
Cannot discuss/compare battery for Omni Pie, since not using Omni
Problem with Camera app does not show on stock Oreo. Even if the app was somehow ported from Huawei, there are maybe problems with integration to Omni.
Various Huawei/Mate models come with different cameras, but there is only one OK Omni ROM (with one Camera app) given to work on all Huawei/Mate models
Btw, somebody else also complained about issues with Camera (and GPS) and decided to go back to stock Oreo.
Similarly, issues you described about black notifications or so must be related to the custom ROM, theme or so.
As a general rule:
- for installing OK ROM, you flash System partition, and nothing else
- you also wipe Data partitiom (containing all your installed apps, incl Magisk Manager, also containing your user settings)
It does not affect any other partition.
Therefore, changes given by NW patch persist - without, you will have (also in that OK ROMs) problems with SIM card(s) and connecting to the network
Also, Magisk, which was flashed to Ramdisk, persists. You must only install Magisk Manager again, because it is user apo, installed to Data partition that was wiped
You must check on the OK side how they advice installing the updates of OK ROMs
(It is questionable if they will get updates any more, since OK team switched to development of ROMs which install over the stock Pie, whereas on P9 you have no stock Pie - only Oreo, and most likely, we will never see stock Pie for P9.
Just check when OK team released last ROM for stock Oreo, and compare with their releases of OK ROMs for stock Pie:
https://openkirin.net/download/
Hence IMO, for updating the OK ROM (if/when it comes), you will again just need to flash its System and to wipe Data (and then to reinstall user apps like Magisk Manager).
Hopefully, you can backup and restore some apps and settings by Titanium.
Whether you don't need to wipe Data for such update - check from the OK support.
On the Open Kirin site you will find Support pages (Faq, HowTo) and also a link to the live Telegram channel
