Again after step 7 when restart ...the message. (only official binary vbmeta allowed). In red .????.

So disturbing .i do googled revise my steps .even on odin this appear.

On thing i noticed. In developer mode .the oem unlock tab not appear at all.. but before was there ....what i miss ?? Any suggestions
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Did you boot to system and verify that bootloader was in fact unlocked, as, vaultkeeper will lock bootloader if you don't boot to system after unlocking...

Edit: if you directly flashed without booting, bootloader will relock and you have to wait for 7 days for OEM unlocking to be available again...
[Samsung Galaxy Tab A series Guides, News, & Discus] drsanusi:
Now. After few days of lineage 19

Works like charm wow ...i am happy how lineage rom evolved over these years .

My main concern is battery life i left the tab for 24hr no any drop at all.before on stock was strange drop .

Other things . brightness fix didnt work .

Now one quistion ..if i want to try another one rom what i do .? From the bigening or what step i start

Thank u in advance
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
If you want to try another ROM, I suggest you to start from setup 15
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Also, the battery drop may be because of GSI roms not setting cpu frequency according to usage, it just locks it at full frequency causing heat and heavy battery drain, try lowering clockspeeds using a kernel manager

edit: I use smart pack kernel manager
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I found the actual brightness fix from the thread which we downloaded kernel from, I added the commands in the OP here...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
If you're flashing big GSIs and flash fails due to insufficient system space, I've added a way to do so in the important notes...
[Samsung Galaxy Tab A series Guides, News, & Discus] wEER1234:
Also! This tab does not have a Vibration motor so you might wanna remove that from the "What doesn't work:-" List.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I didn't know that this didn't have one, thanks for the information, will do the necessary changes now! :)
[Samsung Galaxy Tab A series Guides, News, & Discus] duyfken:
This may be a silly question, but why exactly are we using the SM-T500 firmware here and not the SM-T505 firmware?

samfw.com
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
The firmware is of the t505 version, only the kernel, recovery and other stuff is from t500 as they work and are the only resources available for this device...

Edit: The link preview itself mentioned SM-T505, so, yeah...
[Samsung Galaxy Tab A series Guides, News, & Discus] duyfken:
I ask as Post 1 instructions has SM-T500 firmware, hence why I linked the SM-T505 firmware here.

Also for reference for those trying to work out which type of GSI image to get when downloading one (from a stock as a rock SM-T505):
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Oh my! Thanks for the sharp observation, I corrected it now in the OP

Edit: I also added the type of GSI that should be used for this device!

Edit 2: I also mentioned you in the credits, as you're the one who caught the errors! And once again, thank you very much for the corrections you saved the day!
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
huh? i used it in my stock one ui 4.1 firmware, any custom gsi i ever installed. works fine. try it. you may not be able to install dynamic system updates but installing a gsi through it is very much possible.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
It isn't there for me...
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i tried arrow os 13 new builds by nazim... they were smooth. way better then any gsi i ever tried. but wtf phh treble settings are replaced with something else that is terrible. half of the stuff is gone. then game dashboard also poofed? wtf even game dashboard was in arrow os 12.1. i have to reflash my other gsi again. i should have use dsu sideloader for this... iam very dumb
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
oh you need a seperate application for it. called DSU sideloader. you can find it here. just select your gsi img file let it compress and then enter ur pin when it asks. once done just look at the notification panel. once it asks to reboot. just press restart it will boot into the gsi. after yet another reboot you will be back into your own system. i use the rooted method. there is also ADB commands that does not require root. but the sucess rate is not as high.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Oof, that's sad...

I'll send a screenshot from treble info app, this device runs one ui core so maybe it isn't present because of that...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I'll try it, it didn't work for me previously...

Is this the one you are talking about?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
yeah. it should work?? if samsung cut that in one ui core i am seriously gonna be mad. what the hell samsung.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I'll try it again today, fingers crossed...
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
okayy hope it goes well
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Huh, it needs 40 percent storage to work... I'll free up more space ig...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Yes, dsuloader works with more than 40 percent free space
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
glad to hear that. right now i am trying to get game space to work with arrow os 13 build. its so god damn smooth i want to daily drive this... but some stuff is making me go back
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
nevermind i spotted the game mode i was too blind to see it.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i cant find the gsi .img

edit; it works now
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I got the pixel experience
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Nice, how is it?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
It's pretty good, but lsposed doesn't work sadly, the taskbar size is perfect I just need to put something on it or it will be broken, I put zarchiver on it!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Hmm, it should work just fine try removing magiskhide for the shell app, that is one reason lsposed doesn't work...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
you mean com.android.shell ?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Yes
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
It worked! But ram is always full and crashes my tab, any optimisations? (I mostly game on the device)
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
what gsi ru using? if its PE 13 then use Spark os 13 instead super smooth also have game space. PE 13 is currently in beta and issues like these are bound to happen
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
You have to use smart pack kernel manager and set the swap size to 2GB
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
AFAIK, the kernel we have at the moment doesn't support A13...
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
oh. wierd A12 shouldnt have such issues.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
A12 except swap is mostly stable, but the kernel can't boot any A13 gsi that I tried, ti crashes or reboots to recovery....
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
what one ui version are you on? i had to downgrade to android 11 (one ui 3.1) to get spark os booting. i am loving it. although since i have a diff device idk if it will work for you
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
what the hell. i am just using YouTube in the background. with bluetooth headphones. why only 1.8 gb availible.. i am also using ram swapper from @huskydg
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Can u help me with that?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Can i use microg instead of the normal google gms on pixel experience?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
uhh then you might wana switch to LeOS... its fully degoogled gsi. it has microg and everything.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
But i need pixel experience
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
whats the point of it when you have no gapps? pixel expirience has all the pixel specific apps. if you want microg on it its no point of having PE then. because no exclusive features would work. half of the features will break. if you want to go down the microg route i recommend. LeOS
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
The only reason i want PE is that it has proper gpu speeds
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I found this: https://xdaforums.com/t/mod-flashable-microg-unofficial-installer.3432360/
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i didn't know that. i am suffering from terrible battery life with sometimes laggy but mostly MUCH BETTER THEN STOCK performance. my device heats up here and there when doing simple tasks e.g. listening to music on spotify/youtube in the background. i fixed it to some extent by using kernel auditor by changing cpu governer to ondemand. any PE except v414 doesnt boot for me.
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
still tho you can give LeOs a go with dsu sideloader
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Can u help me install the microg?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Is there a way i can install twrp on samsung m22?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i have personally never installed it myself. you should degoogle your system first that's why i think i may be wrong. you can find tutorials on youtube
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
C

An u send me a vid?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
if there is a twrp build availible for it then yes. check its XDA forums and follow the instructions there.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I can only find for A22, wish i got it instead
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
you could try this one
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
don't worry you can post a thread there asking for devs to work on it. it will come for it soon. if you want to install a gsi maybe you could use the unpack and repack .sh using odin. although it is only tested for galaxy A32 and galaxy A12. if it bricks your device you can flash the old firmware again
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I only need it when warranty finishes
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
oh i was gonna do the same but samsung fooked me with an update killing half of the CRTICIAL stuff. i was forced to void warranty and trip Knox screw you samsung
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
that stuff is still broken e.g. fingerprint mobile data. mobile data was fixed with an gsi but not fingerprint.. its just gone never coming back. the sensor itself may have died but i cant send it for repair
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Im on february 2022 update, which one where u on?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
You can repair it yourself, just request the part from samsung
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i am using a different device as i said. i own a galaxy A32 4G. mobile data bug was fixed by downgrading... but fingerprint is never coming back. its gone...
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i dont have the skills nor stuff to do it properly i dont wana end up with a half working main device
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Ik but im asking which update your using?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
last one was august. right now i downgraded to A11 update then flashed android 13 gsi on top of it. loving itt
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Send it to a 3rd party, just keep an extra eye to watch them, you know why
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
i think i am fine for now i'll see later
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Ok, im lucky my tab doesnt even have fingerprint or 4g i got the t500 not the t505
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
It just says no root
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
then give it root
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
It doesnt ask for root it just says no root
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
seems like you dont have magisk installed there is an easy way to do so without wiping data
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I have magisk delta bruh
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
wtffff. you could go into magisk manager super user tab and maybe grant it there. if its turned off for the manager turn it on
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Nope
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
try reinstalling the kernel manager.... otherwise you could also try kernel auditor
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Nope, is there a link for kernel auditor?
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I need to set the swap size to 2GB
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Both dont work bruh
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
you could use ram swapper module for magisk then. install fox's magisk module manager. grant it root permissions. let it download the list of modules as soon as new modules appear tap the search icon on right bottom. type swapram. install it. reboot. after that download terminal emulator. type in "su". grant it root perms. then type swapram add [ammount of ram]

replace [ammount of ram] with your desired ammount in GB. i use this module.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I fixed it, it was just my magisk settings lol
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
hehe told ya
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
after flashing the product.img, run command fastboot erase system and then flash the twrp 3.6.0, i didnt resize the system participant, i continue to flash the dynapatch, reboot to recovery again and then i wiped cache, dalvik cache, i flashed pixel experience a/b slim and then the t500 kernel that you attached. After that i reboot the device and it got stucked into bootloop with no bootanimation. Now i cant get into both recovery and download mode. Any suggestion or solution for this?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
What is the model of your device? If it's something along the lines of t505N or something else, this can be expected, if not, im not sure, you could hold the power volume up and volume down keys for 5 seconds and then hold both the volume keys again to get into download mode if you're stuck in a no boot animation bootloop, and, as for recovery mode, I have never been able to access it from key combinations, I always have to reboot to recovery...
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
My device is T505 and is the download mode accessable by plugging the device into the charger brick and not a computer?
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
Can anyone share the link to the ProtonAOSP/ PE gsi that booted on their device? I can't find any of those to be able to boot on my device
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
OHHHHHH so will it be able to boot if i dont flash the kernel or i need to downgrade
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
proton AOSP is very outdated and i have heard its buggy. it didnt boot for me. i have a completely diff device. idk why i am on this thread lmao.
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
You must be connected to a computer to access download mode...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
You have to downgrade to one UI 3.1 as the kernel will result in a bootloop if you flash it on one UI 4.1...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
The pixel experience 12.1 gsis used to boot, but for some reason they bootloop if I try them now... (Basically gsis are not working at all for me even on downgrading...)
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
T

They work for me im on android 11 and didnt update
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Don't update to one UI 4.1 as long as you want to run gsis for now...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
oki!
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i dont even update my tab or non roooted phone
[Samsung Galaxy Tab A series Guides, News, & Discus] Shadow128:
As in the other LineageOS19 thread writte I've bought the last days a SM-T500 Tablet, which works almost good. Now I've updated it to an current Andy Yan GSI ROM (lineage-19.1-20221011-UNOFFICIAL-arm64_bgS-vndklite) and here I've also the same problem like in the LineageOS19 rom from the other thread.

After some time of using (during chrome or a game) it has a slowdown and sometimes it come's back, sometimes I've to reboot it.

I found some hints for a Z Ram fix, which should be the following?!

Where do I find that module? I searched with the module manager, but didn't find it. Via google only https://github.com/VR-25/zram-swap-manager but I think it's something different?
[Samsung Galaxy Tab A series Guides, News, & Discus] Captain_cookie_200:
that module got removed. gotta find another one
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
its not a module, i use smartpack
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Hey all, it's been a long while, but here's a small peek into what I was ble to run on latest one ui 4.x vendor this weekend, I will update the future soon on how to run A13 GSIs...
[Samsung Galaxy Tab A series Guides, News, & Discus] Shadow128:
I found that magisk moduole from a previous fork of the original repo. So now the tablet is working very great and smooth :)
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
did you flash the kernel that you attached in the original post
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
No, it results in a bootloop, and it doesn't install on A13 either way...
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
lol so you used another kernel or just the stock kernel
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Stock kernel
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
ZAMM nice, lemme try some a13 gsi tonight, One UI 4.x is so lag on this
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Also, 2GB of swap is allocated by default, so, no need for magisk modules to get SWAP...
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
wait so to be clear that the tutorial is the same as before just don't flash the t500 kernel then im good to go?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
No, I rewrote the first post, don't read the second post, is there for legacy reasons
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
ah ok lemme try it tonight
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
There's a command that needs to be run at every boot for the GSI not to randomly reboot! Also, the work in progress in the title indicates that i have to describe some workarounds like for headsets,etc, but the GSI flashing and running part is complete
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Also, don't use trebledroid GSIs they are buggy(magisk also won't work for them for some reason :( )... So far pixel experience is stable...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Check post #1 for A13 GSIs, is fully updated now...
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
can you send me the link to PE A13 gsi that you used to flash?

[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Nice work! The only thing I would say is after you flash the gsi is to do a factory reset before booting,, I've been looking for away to just flash the recovery.img instead of using Odin for sense I feel Odin doesn't actually know we're to put it on its own!! But if no one else has made a module for the command I'll look into how to make one sense I'm running lineageOS 20 on my smt500 and it doesn't start randomly restart after I set zigiest and flash gapps!!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
The problem i have with odin is that if the power goes out while doing something, I'm scared that it'll hardbrick..., I'll add the factory reset part now, thanks for the mention! And the random reboots are due to watchdog service used by samsung... (That's what the command disables...)
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
oh nice thanks
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Yea I feel that!! I've hard bricked plenty of phones on accident but it's the matter of the right software To bring them back, I had a straight talk s3 back in the day I killed and the qualcomm chip was still able to talk to the computer so you could send the stock firmware through a program or command it's been awhile so don't quite remember if it was Odin or cmd. And noice sounds good!! And if I teach my self something new or fine a way to shut down the watchdog with out breaking something else I'll post it here!!?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Actually there's no need to rediscover how to disable watchdog, all we need is a way to disable it on boot as of now, but if you find a permanent solution, do post it!
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Oh most definitely!!!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Another small piece of info, I was able to modify @mrspeccy brightness fix module to include the watchdog fix command, so, now you can just install that module in post #1 which fixes brightness and watchdog together...
