[Honor 6X Questions & Answers] CodingAddict704:
so i have a bln-l22 on rr 8.1 and magisk and wanted to install pix3lify so i installed it and got stuck in a bootloop so i booted into twrp and tried to flash the magisk manger for twrp and doesn't work then tried the SUmount and it didn't work too so i tried the uninstaller from the original magisk thread didn't work too so i tried using a touch command to create ".disable_magisk" in /cache and that didn't work too, so please i really need help here. and thanks
[Honor 6X Questions & Answers] RedSkull23:
If you've already tried latest uninstaller and system still can't boot, I'd say that you'll need to factory reset it. If things won't fix either this way even if I don't think so, probably reflashing stock EMUI 8.0 ROM to fix boot.img and other affected partitions (if there are) and then reflashing RR would be another solution.
[Honor 6X Questions & Answers] :
Just use Hurupdater to restore firmware. It will wipe all your user data and requires you to have TWRP recovery
[Honor 6X Questions & Answers] CodingAddict704:
hey can u help me with a guide to to go back to EMUI 8 from RR please ?
[Honor 6X Questions & Answers] RedSkull23:
The fastest way if you have TWRP (i guess so since that you're rooted) is to rely on HuRUpdater, as the user Mannan Qamar said above.
[Honor 6X Questions & Answers] :
And if you want instructions I am more than happy to help.
[Honor 6X Questions & Answers] CodingAddict704:
yeah, it would be very useful because i just followed what was on the thread and still bootlooping -_-
[Honor 6X Questions & Answers] :
Since you already flashed once I am sure you don't have TWRP recovery anymore. And that you are on EMUI 8 India. So first Order of business is to flash TWRP. While the device is bootlooping plug device into PC and hold Power and Volume Down button. As soon as screen turns off release Power Button but keep holding Volume Down. Your device should boot into bootloader. Flash TWRP recovery from Elemental ROM thread.

Now download Hurupdater 0.4.zip from thread and the firmware for your model. Rename the firmware files as suggested in Hurupdater thread and place them all in the same folder on your SD card.

Now boot into TWRP with Power & Volume Up. Go to Wipe & Format Data. -> YES.

Now go-to Wipe-> Advanced Wipe-> Select:

Dalvik/Art Cache

Cache

Internal

System

Data.

And swipe to Wipe. Only mark these and nothing else. Now go to install, select SD card and navigate to the folder in which all the Zips are present and then select only Hurupdater to flash. Now pressbVolume Down when it prompts. Flashing will take around 10 mins. Be patient. You will also get error of no recovery.img and some other. They're normal.

After flash complete wipe Cache/Dalvik and then reboot system now. In the warning screen, press Volume Up to boot into erecovery and Perform Factory reset. Then format Cache and reboot system now. First boot will take around 10+min. Don't panic. Luck

Instructions

It is STRONGLY recommended to fully wipe your device before flashing and please avoid restoring system apps and system data with Titanium Backup as this can cause stability issues that are very hard to debug.

If you believe you know what you're doing - then fine, go ahead, but please don't complain if you experience any strange behavior.

How to flash:

(Again: Don't do it if you don't know it!)

1. Download the ROM and GApps and transfer them to your device.

2. Boot to recovery (TWRP recommended).

3. Wipe the System, Cache, Data and ART/Dalvik cache.

4. Flash the ROM Zipfile.

5. Flash the GApps (optional, needed for e.g. Google Playstore to work).

6. Flash the root solution of your choice (optional).

7. Reboot your device.

Reporting bugs:

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /sys/fs/pstore/console-ramoops and /sys/fs/pstore/dmesg-ramoops-0. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. Any bug not reported in the bug report format below may be ignored.

What is your--
LineageOS version:
LineageOS Download url:
Gapps version:

Did you--
wipe:
restore with titanium backup:
reboot after having the issue:

Are you using--
a task killer:
a non-stock kernel:
other modifications:

Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:

Issues

- SELinux permissive

- encryption

- audio through speakers is broken, headsets and bluetooth audio works

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheMadScientist:
I can say it possibly a bad download or something on your end I flashed this last night with very few issues I have not used LOS in a long time but I was impressed
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DJCodeBlue:
For some odd reason it's not working for me. At first it gave me Error 7 code telling me that my device isn't a T550. Then I manually removed the "assert" check lines from the ZIP file to force the install without a device check. It installed. But I can't boot into the OS. It just kicks me back to TWRP every time.

Never mind, after trying once more, it finally worked.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheMadScientist:
Hey does this lag like crazy for you

even setup took me forever to get passed I normally let a new flash sit around for about a hour to the the system calm down still real laggish
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DJCodeBlue:
It wasn't that bad actually, it seemed to settle in for me. But I switched back to an Oreo rom for the time being for the bugs to get ironed out. Now I'm dealing with a super sluggish ROM lol. Do you have any recommendations for a good Oreo debloated ROM that performs great on the T550?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] TheMadScientist:
Not oreo im trying to find anything that dont lag now

I ended flashing stock nougat and rooting it...

Been working on that....

I got so used to my s8 This tablet seems kinda slow lol:p:p:p I tried another rom I think that jazz rom but about the same lag and I couldnt remove home screen icons without uninstalling them the little popup menu wouldnt work

---------- Post added at 07:14 AM ---------- Previous post was at 07:13 AM ----------

I still have expectations for this old tablet without any doubts there are a few of us out here with the 550 so we can band together and get something going I just got mine so Im stuck with the device for a while
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Switched from a S8 to this tablet, that's real fortitude .. May I ask why you did this? The tablet is already antique. This is called a feature for slowing movement. Audio is working now, I will upload a new build tomorrow. I was able to install gapps without any problem and I don't feel like the device is "laggy as hell". Make sure to select Android 9 and ARM at opengapps.org, I choose always pico there and have no issues.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Sometimes that issue is caused by TWRP. It means that TWRP fails to get the device model, which is required for new install scripts. Consider updating TWRP.

Please make build for T555 (I tried to edit it, but then the animation doesn’t start up )

Put your aicp 13.1, which you did not even publish here, but there are two errors: the camera does not work, and there is no sound except vibro
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
I don't even get why you are trying to point the finger at me because of this. Trying to edit compiled builds is very dumb. Go ahead and compile it from scratch. I don't own a SM-T555 -> I can't test my builds properly. The result is a half-broken always-alpha build like the one on my afh account. That's the reason why there is no thread. Feel free to donate me that tablet, maybe I find some time to build it then for you.

I've updated the SM-T550 build now btw, audio is working now. I've tested the gapps-setup, too. It took me 30 seconds to get through. The device was fully wiped, maybe that's the reason for the speed..

Everything I need works fine

I just started thinking about using my old Samsung Tablet again as a remote.

When I saw that there is a LineageOS build available I just installed it.

Everything I need to use my tablet as a remote works perfectly fine and way better and faster than with the crappy touchwiz on our device.

Installation was done in 15 minutes or even less.

Thank you very much for your efforts!

Waiting for the stable version for this...

Thanks Virsys to keep alive this fossile :D
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Good morning layman,

the version is quite stable actually. The only things missing are SELinux and the encryption/decryption of the internal storage does not work. May I ask you for the build number of the original operating system made by Samsung? These builds are for the SM-T550/gt510wifi/Samsung Galaxy Tab A 9.7 WiFi only. Have you enabled OEM unlocking in the developer options if there is this option?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] layman22:
Dear Virsys, now I'm using your Oreo AICP build, so I can't tell you the original Samsung os's build number unfortunately...

But it was crap with full of needless ****s :laugh:

Than now I'll test this Pie build soon!

Thanks for your reply and have a nice day! ;)
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] DazzaHoy:
My model: SM-T550

Just tried to flash and when it starts i get

Android System

There,s an internal problem with your device . Contact your manufacture for details.

When i start to setup if i skip wifi setup all goes fine but if i sign into wifi i get setup has stopped , other than that all else works great.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
It's still an alpha version and it will stay alpha until LineageOS 16.0 is officially released. To minimize the bugs avoid dirty flashing and restoring apps with titanium backup. Use ARM Pie gapps from opengapps.org, I recommend using nano or pico.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] isaacmvmv05:
Thanks! I will do it
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
I am compiling the official Lineage OS sources with no modifications. You can always check the changelog for those sources here: https://www.lineageoslog.com/16.0

Device-specific changes can be reviewed on my GitHub account in the gt510wifi device repo. Because I am working on Android 10 right now there are basically no changes to the Pie branch, though.

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] AsukaZata8:
The SM-T550 coming soon about Android 10?? I mean, you have not problem the lineageOS? Is official your tablet? If you have SM-T555? As yes, I have too SM-T555. If your tablet doesn't work for lineageOS 16 (No SIM) - 4G? Don't worry this tablet. I will working about lineageOS 17.0 the Model only SM-T555 and I don't know who has working the Model SM-T550?

Thanks for your post! Soon...
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Erm.. what's your point AsukaZata8? Do you want to start developing for the SM-T555? LineageOS for those two tablets will probably never reach the requirements for an official build, because things like encryption and DRM were broken in lineage-16.0. Even though I am trying to get android 10 running, there are still major bugs regarding vold and vendor blobs. Still a lot of work to do there.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] elwhiteboy01:
Hey virsys, question, so if you get 10 working you'll stop work with 9? Just curious. Either way, I appreciate your Dev skills and your contribution to the sm-t550.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
I won't support two versions of android. Just like oreo, pie will be discontinued after I get 10 running. If that is not possible with our old hardware and my limited knowledge, we'll keep improving 9 and updating.

Hey everyone!

I was about to get rid of my SM-T550 as it has become slower and slower over the years.

But then I thought, why not try a new rom first?

Now it has been some time since I last flashed a device (last was an older smartphone several years ago - preLineageOS)

So, quick question: where do I get the correct GApps for this rom here? I tried google of course, but the amount of different versions and rather dubious download sites made me hesitant.

So I thought I'll ask here instead.

Thank you all for reading and thank you virsys for working on this!

EDIT: I think I got it. Turns out when looking on your phone or tablet, you don't get the really good answers ;)

Well ****.

I finally found a root file, managed to root my T550, installed TWRP, and flashed the LineageOS + GApps.

But now the Tab is completely locked. Screen is black and no combination of buttons (power, volume, home) has any effect.

I am grateful for any help here.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Have you managed to fix it yet? This should not be possible by just flashing some bad zips in TWRP. Probably something went wrong and you are stuck in the booting process. The force reboot command is Vol Down + Power + Home at the same time, does that help? Or maybe it discharged and needs some juice, plugging it in for a few minutes could do the trick as well.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] devicer:
Can you share files/method to root this device? All my tries failed. TY in advance
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
The latest Magisk release is recommended for rooting, just flash the .zip in TWRP. In case you are on stock and have no custom recovery, flash the TWRP .tar using the Odin method described here:

[Samsung Galaxy Tab A series ROMs, Kernels, Recover] Peabody0815:
Hey [MENTION=8846360]virsys[/MENTION]:

I finally managed to get it to work.

The issue seemed to be that after flashing your OS rom, TWRP always asks whether TRWP should be installed as well again. That step seemed to drain my battery.

Once I skipped that step, the OS finally booted.

One question though:

The OS constantly warns me about two things:

1) SELinux is deactivated and can't be activated. Is that the encryption issue you mentioned as an open "bug"?

2) It also warns about that the OS(?) was signed with a public key.

Would you be able to shed some light onto those points?

Thank you for all your time and effort!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Great that you were able to install it properly now. SELinux is not really related to encryption. It is rather a security model developed by the NSA in order to restrict access to system files. Since some device functions like the camera were not working with SELinux enabled, I turned it off again. Writing efficient SELinux rules needs a lot of time and reading for an unexperienced individual like me. For now I want to invest this time in developing android 10.

My builds are "signed" with the keys that come with AOSP, so those are public. On the other hand private keys are used by large corporations in order to verify data integrity. The only custom rom with private keys I am aware of is LineageOS official. Since my OS is custom and I don't really have a reputable key to verify, signing my builds is not my priority either. I can look at it on android 10 as well, I'll add it to my list.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StarryMinecart:
Hi,

I installed this ROM but there was an problem. After "Patching system image unconditionally", it prompts "E1001: Failed to update system image" and then error 7 appears.

How can I solve this problem?

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
This error code stands in most cases for a failed assertion. The installation script verifies whether your device code is the same with the one noted in the .zip file. The ROM linked in this thread is for the SM-T550 only.

When this is not the case, please clean flash the latest Android made by Samsung with Odin, install twrp official and try again.

I flashed the latest Android made by Samsung with Odin and installed twrp offcial and tried to flash it again,but...the same problem appeared.Maybe this is because my device's region is CHN and this ROM is not compatible with it?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ascendence:
hey guys, so how does this perform on that tablet? is it worth going through the hassle? is it useable? faster than the stock rom?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
I don't think that flashing this ROM on Chinese devices is any different. But on the other side I am not based in China so I can not confirm anything on my own. Does the global Samsung firmware work on your tablet?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] virsys:
Only by trying you will get a reliable answer. For browsing or usual apps it is faster for me, but DRM is broken so things like Amazon Prime Video or Netflix will require some work to function properly.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] StarryMinecart:
