Hi,
about 2 years ago I rooted my S2 Galaxy Tab (T719) and now I would like to upgrade from Android 6.0.1 to Android version to 7 or 8. I have googled for instructions on how to upgrade a rooted S2 Tab but did not find anything useful (most info is on OTA upgrades which no longer works on rooted devices). Could someone please post step-by-step instructions (please bear in mind that I only ever deal with this kind of thing once every 2-3 years so I do not have much experience). I have TWRP v 3.0.2 installed (do I need to update this as well?) and the tablet is not encrypted (so hopefully I won't have to wipe the system partition and re-install all the app?!?). Thanks.
I also noticed that there is now a huge variety of ROMs out there. How can one know which ones are trustworthy? The main reason I rooted the tablet was to be able to increase privacy (control app permissions with XPrivacy). So I do not want to install some custom ROM that maybe contains spyware or other compromising features. Any advice on this would be greatly appreciated. Given my motivation (privacy) for rooting, would it maybe be better to go back to Stock ROMs (i.e. non rooted) and simply control web access via netguard (by preventing net access for some apps, they may still spy on my contacts, location, or email but cannot phone home to transmit the information)? At least I would still get OTA updates because being excluded from the OTA channel also poses a security risk in itself I suppose. Ok so any advice would be appreciated.
Thank you in advance!
There is no official Android 8 for our device. If you want 8 or 9 you have to install a custom ROM like LuK1337's LineageOS port. It is as safe as LineageOS is by itself on any device. Only problem you might have then is that calling is not possible anymore for now, but LTE works. If you want to use LOS, you HAVE to format data because it's not compatible at all. If you wanna stay on official Android you might keep it. Installing is done by flashing the official firmware with the correct country code over Odin. This will remove TWRP at first so you have to reflash it by Odin afterwards. For firmware download I always use: https://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 and Odin is found by google. If you wanna got the way to LOS you have to do all the steps I mentioned before too anyways to have a recent Modem firmware and bootloader. In that case you just have to flash LOS and OpenGAPPS by TWRP and delete /data aka Factory reset.
Regardless what you do, after ODIN is done, you HAVE TO boot into TWRP immediately to keep it from being removed by official firmware. While you are in there anyways you can install magisk to keep it from encrypting /data
Many thanks emuandco. So I guess I will stick with the Android 7 as I do not want to reformat the tablet and reinstall all the apps. I have started to download the Android 7 stock ROM, but it is taking quite long so in the meantime just to confirm, the steps to follow are:
1- use odin to flash the stock ROM (no steps required prior to this? I simply overwrite the existing ROM? I suppose that I will loose root then and need to re-root the device using the standard procedure as explained here: http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html ?)
2- use odin to flash TWRP (I will need the newest version I guess and cannot use the same as for Android 6?)
3- boot into recovery mode to ensure that TWRP does not get overwritten
4- done
Is this correct? Do I then need to reinstall Xposed, SuperSU and Xprivacy or will they be preserved?
Thanks again!
P.S.: BTW, I also found these instructions: https://forum.xda-developers.com/tab-s2/development/twrp-3-0-2-1-galaxy-tab-s22016-sm-t713-t3390627 which are slightly different from http://www.samsungsfour.com/tutoria...nougat-7-0-using-cf-auto-root-all-models.html and require a wipe of the data partition. Does this mean that for an update to Android 7 I definitely do need to wipe the data partition? If this is the case then this would be a major disadvantage of rooting in the first place and maybe I simply flash the stock ROM and do not root at all but go the "netguard" route as mentioned in my original message?
I never used the official Firmware that much. Fist thing I did was going on LuK1337's nerves to get a port of LOS for it up and running So no clue if Samsung manages to keep /data but I guess so. Yeah, looks fine what you list there. You COMPLETELY overwrite ANY modification in kernel or /system, so reflash your mods and root (Magisk). I always recommend to uase the MOST recent TWRP. (https://dl.twrp.me/gts28velte/ should be it in your case).
Ah and looking at your manuals... Check OEM unlock just to be rather safe than sorry if things go mad.

Hello!
I'm a bit of a noob with the whole Android scene, but I hope to one day be able to fully understand the root process and how magisk works, but as of right now I'm in a bit of a conundrum.
As some of you know, Samsung is pretty rough when it comes to rooting, particularly with the OEM problems and the Knox e-fuse. Dr. Ketan made a fix for the OEM problems, using a special tool which installs magisk 18.
However, I want to upgrade to magisk 20, but I'm not sure if the SM-G965N (S9+, Korean version) can actually run it.
Now, the question:
Does anybody know if I can just install it normally via TWRP like with any other phone? Or I'm stuck on magisk 18 until another developer updates the ketan OEM fix to magisk 20?
And secondly, can I update my phone to Android 10 and still install magisk normally, if the latest version of magisk supports the S9+? A while back they released the Android 10 update in Sammobile, but I don't know if I can flash my phone and still be able to run magisk in it.
Thanks in advance!
EDIT: I used the old Android 8 method (No-verity-opt-encrypt 6.0, RMM Bypass and Magisk 20.3) and it just bricked my device. It was stuck on the Samsung S9+ screen, so that was a no go. Had to revert to my latest backup via TWRP
Hi everyone,
I had updated my Galaxy Note 9 with March 2020 update and I am one among many poor souls who are suffering from display discoloration, horizontal lines during low brightness and over heating.
- I have tried all possible methods as suggested by Samsung team in their US community page, tried factory reset multiple times, nothing worked. Took screenshots of the screen and shared it to other to check if the problem is with display, but the screenshots were just fine, no colour distortion or verticle lines. So i am of the opinion that, its basically software glitch in March update.
So, I have some following specific queries. I tried looking for these queries in the forum but did not find any, so, have collated all my queries below:
- My current Bootloader version is 5. Is there any process by which i can downgrade my Bootloader from 5 to 4? I would like to go back to January update.
- If I root my phone and install custom rom (latest version of Linage OS. You guys can suggest a good OS, if you have tried one), will the display problem be solved?
- After installing custom rom as mentioned above, can I go back and install stock firmware with Bootloader version 4?
As you can see, I am just trying to find a solution to come out of display problem. Any other suggestions or any tried and tested solutions are welcome.
Thanks everyone in advance

I am facing same issue ...display distortion from 20% to 80% ..after that display looks fine.
I tried to downgrade to pie ..still no success...it has same issue...
I also believe that its software issue or some connection issue
Sue samsung for trying to force user to change screen. Samsung's screen is so expensive. Apple was fined for throttling the iphones.
I have same issue on my N9600... :'(
What is causing the distortion? Sofware bug? Can shot a picture showing the issue?

Ita all over the internet. Just Google Samsung galaxy note 9 display discoloration.
I don't know if this will solve your problem but you would be able to flash a Android 9 ROM on a Android 10 bootloader. If you're like me you hate Android 10. What you do is you flash Android 9 bootloader made for twrp flash the Android 9 rom of your choice. Than flash the Android 10 bootloader that you want via Odin, than fastly reflash twrp for Android 10
For me it works but I kind of jerry-rigged it to work. I regret every day updating to Android 10 but since I'm able to still run Android 9 on an Android 10 bootloader, I'm okay with that.
Hope this kind of help you.

only way is to trip knox by rooting and then flashing an android 9 rom. as you know once it has been tripped you will instantly lose access to samsung pay, secure folders etc. however on the plus side you have the choice of root or non root.
Hi guys,
Me and my mum are experiencing a similar situation.... I'm trying to downgrade my galaxy Note8 boot-loader, everything was working till I press the button to upgrade. Now I cant use any memory card all i see is 'the Sandisk card is not supported' and for my mum's Note 9 when she activates the biometric sensor the phone restarts each 15 - 30 mins. I always bought Samsung but now I'm considering to don't do it anymore...

Hi, ok so assuming we don't care about tripping knox, rooting and flash.. still, how would this be done?
I'm on a SM-N9600 atm, with latest Android 10, rooted and TWRP installed. Where do I find a custom Android 9 Rom (compatible with my model) that I can flash via TWRP?
Thanks in advance

All you do is just flash the android 9 rom. Downgrading the bootloader makes no difference if you have already unlocked it. The whole point of it is for people who are on later bootloaders and still have knox and want to go to android 9 which is not possible without the trip.

Hi @A|ex , thanks for your answer. I still don't know where I can find a custom Android 9 rom, compatible with Note 9 snapdragon (SM-N9600) that I could flash via TWRP... (Assuming it's impossible to flash stock Android 9 via Odin even if my phone is currently already rooted on latest Android 10 (bootloader == 5).
Here on XDA there are some ROMs for the Exynos model but nothing except the 'WETA' rom for Snapdragon model, which is not a full rom anyway from what I understand.
If you could shed some light on this it would be much appreciated: where can I find a custom Android 9 rom, flashable via TWRP, compatible with a rooted SM-N9600 (currently on latest Android 10, with a BL==5, unlocked)?
Thanks again for any help!!
I have this phone P9 since 2016 and I still love to use it, but I can't update it anymore.. I have already rooted the phone and install TWRP recovery, is there a way to update this phone to android 10?

Huawei stopped supporting the phone, last official updates were Nougat.
For Chinese market last update was Oreo - by rebranding, you can install and use it worldwide (find and follow HWOTA-7 thread from the ROMs section ).
Upon rebranding and installing that Chinese Oreo, you can install LOS (AFAIK, 16.0 - again, look into the ROMs section
There is no such thing as A10 for this phone (maybe you could find A9 GSI - again, upon finishing HWOTA-7 and Chinese Oreo), but of questional usability

On that day, the newest magisk version was 25.0, I followed all the steps in the above thread but the device was still bricked (boot loop).
I searched the error log and figured out that this was due to something called "avb flag":
Samsung system init check fstab avb flag cause boot loop · Issue #6141 · topjohnwu/Magisk

github.com
Since I don't have much time on this, I simply did a factory reset and kept using the tab without root.
I am actually not sure whether the "avb flag" is the root cause. The only thing I am sure of is using magisk 25.0 and s8ultra android 13 ROM leads to a boot loop.
Today, I found that magisk is now updated to 25.3, and nobody here mentioned the boot loop.
So, I want to know whether magisk 25.3 is working well with the newest ROM. If it works OK, I will give it another try.
I have a Tab S8 Ultra which was on Android 12 / OneUI 4.1 rooted / Magisk. I just finished updating it to Android 13 (image SM-X906B_2_20221208191241_81t9w4gald_fac) without any dramas. I did a factory reset before flashing the patched AP, not sure if that helped avoid any potential bricks or you were just unlucky.
I'm only on Magisk 25.2 though - I don't see the 25.3 that you mention anywhere. So make sure you're downloading from topjohnwu's GitHub page, not some other sketchy place. That might be a factor.

Well, I think “25.3” is a typo. I always download the magisk APK from github. I also tried a factory reset.
May the issue is already fixed in a way. I'll try it again some time.
