ZAMM nice, appreciate that
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Just out of curiosity, do you have a strong internet connection without any limits on usage?
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
well I do
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
If possible, and only if you want to, do try as many GSIs of A13 as you can and report whether they work or don't, and which is the most stable, etc... (As I'm on a limited data plan, i can't download more than one GSI per day)

Edit: What I've deduced so far is that

1. Trebledroid GSIs are a no go on this device as magisk won't work

2. Pixel experience GSI is nice and stable and magisk also works on it

3. Google GSIs are way too barebones and lack basic fixes
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
I did find this but I'm at work and my z fold 4 arrived so I haven't got the chance to do much about it yet
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I already modified an existing module to do the same, and it works flawlessly!
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Right on I don't suppose you can share said module lol I finally tried zigist back on and now it's restarting
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Um, i attached the module in post #1 itself, is right next to dynapatch...
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Oops I did see ill take a look, oh you added it to your brightness fix my smt500 won't flash that unfortunately, so imma just need to put my big boy pants o. And make something myself lol
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
You need to install it from magisk, not twrp, are you trying from twrp?

Edit: I downloaded the module from here itself and it flashes on my device...
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Yes I was ill give that a shot now!!!

update:: Ooffttaa I never said I was the brightest bulb from the bunch but it did flash through magsik and brightness worked at first then I turned but after turning zygist on brightness stopped but removed the module with zygist on and re flashed see how this goes!! No cigar on the SMT500 it the brightness doesn't like zygist but I don't have random reboots and zygist is on so extra dim toggle will doo for mee, thank you 😊
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Actually, zygisk works on my end, actually, try permissiver_v5 in twrp and then the magisk module...

Also, do not rely on the extra dim toggtoggle, i ruined the edges of my screen due to the panel overheating, what extra dim seems to do is an overlay to make the brightness seem leader...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
https://androidfilehost.com/?fid=6006931924117940902

This is permissiver, download it and flash in twrp, then install magisk module, both watchdog and brightness fix should work...
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Okie dokie ill do that and going through my down loads I just realized you don't have the latest dynapatch
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I didn't test the newest version, but the older one is working just fine so,... , Also, is it stable for you? (If it's stable I'll add it in)
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Aww noice it worked sweet thank you, and to be honest I didn't think of that I just assumed it was how everything is running ATM I can only assume it's stable
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
So, did you try permissiver, and, if yes, is everything working as normal? (Namely zygisk)
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Yes yes it is my kind sir, you've helped alot take care of this head ace blahahah now only if I didn't need to flash mulitdisabler everytime I need to flash something that should require a format, boy do I m8ss the old days of rooting and recovery balala
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Actually, since you're not running one UI anymore, flashing multidisabler is not needed every time, as long as you flashed the disable dm Verity package in twrp, which entirely disables storage encryption...
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Huh really? But are you talking about the vbmeta disabled r tar? I don't believe I have seen anyone talk about that in the smt500 posts!!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
No, after a GSI is installed, vaultkeeper is becoming tame, as only one UI can use that to lock you out if you don't connect to internet...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Also, if you patch your AP file using magisk, you won't need any vbmeta manual flash as magisk takes care of vbmeta during the patch process...
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
Huh that's something new I haven't found yet on any posts I just downloaded one is there one that's been updated after disable_dm-vertity_forceEncrypt_20201008?

And yes I found that out pretty quick as well magsik has been updated to have vbmeta disabler built in!!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Afaik that should work without issues... (disable_dm-vertity_forceEncrypt_20201008)
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
The only issue is it doesn't help with I'm seeing is backup in twrp update:: never-ending it does it just has to be format data not just a factory reset
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
Sure I'll but for some reason I currently cant expand system partition idk why

edit: nvm i figured out that i need .\ before the command lol
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
There's also steps in post #1, to expand system partition...

Edit

If the gsi ROM you're trying to flash doesn't fit on current system partition, then,

*This process will wipe your system partition and will reset your recovery, so, keep the dynapatch zip and gsi image on hand, you will need it!*

Download latest platform tools from AOSP site, link below

SDK Platform Tools release notes | Android Studio | Android Developers

Android SDK Platform-Tools is a component for the Android SDK.

developer.android.com

https://xdaforums.com/t/...xy-tab-a7-10-4-sm-t500.4371123/#post-86050459

a) download the product.img from above link

b)Reboot to recovery from magisk app, then, in twrp, click on 'Reboot' button

c) click 'fastboot'

d) the device will now reboot and then after a few seconds, a twrp ui will appear with the text 'fastboot'

e) connect your device to a pc with the latest version of platform tools and drivers installed

f) run these commands in order

fastboot flash product product.img

fastboot erase system

fastboot resize-logical-partition system 3940000000

fastboot reboot recovery

g) after doing so, again reboot to recovery, flash dynapatch zip first

h) again reboot to recovery and flash your gsi image

i) this time images up to 3.9GB will be flashable

j) no need to format data if you're flashing same rom

And that's it you'll be able to enjoy bigger ROMs on your Galaxy Tab A7!
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
thanks

btw do you have any solution to make this taskbar on PE look a bit... not weird
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
No, sadly i have no solution, and it's an issue on the mainstream PE as well, and also, i used the full size taskbar, which for me felt too clunky and took up more space on the bottom on the screen...

Edit: its the same for me as well, just to be clear...
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
How did you enable full size taskbar

I cant find any option to change that as well
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I tried trebledroid GSI which had full size taskbar... (Which of course I'm not using at the moment)
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
ah ok, lemme try with evo X gsi
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Sure, report back on what works and what doesn't, and, also, did all 4 speakers work on setting convolver to 100%?
[Samsung Galaxy Tab A series Guides, News, & Discus] Pewdeadcake:
it didnt work tho, still 2 speakers only but if i change it to 50% I will get 3 speakers working, the bottom right one don't work

Btw how did you make the headphone jack to work, i cant find any option related to it in the phh setting
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Follow the updated step 1.2 in important notes, i made a mistake, the option is in Misc features not Samsung features

Edit: For me all speakers work on setting convolver to 100%, strange...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
nice, does the custom rom support sim card?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
It of course does as long as your device has a sim slot, i.e. SM-T505!

The post #1 has been updated to run Android 13 GSIs too, take a look at it and try it!
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Id stick with android 12, i usually stick with older versions, and i didnt update my stock rom to oneui 4.0
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
@Hausemaster Oh do I feel dumb lol I didn't realize I needed to flash both multidisabler and the disable.zip facepalm but I now running a smooth ineageOS 20 secured so I now have work gapps again with back up and restore!!! I'll keep you updated But for the magsikhide I as well recommend hiding ad services and any thing else API related and I'll update on what I find works the best and doesn't, as we ell I did find this module for removing boot warnings but didn't seem to work for me it flash through magsick fine but as far as I see no changes if you like when I get a chance I can attach it if you wanna play around with it!!!
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Nah, I cant play around with pram based mods(i.e. boot warnings and other things are stored under pram),as the hdd in my ancient laptop could fail and leave me stranded. Also, congrats on your success!
[Samsung Galaxy Tab A series Guides, News, & Discus] shorty9210:
I feel it if I find out more about it I'll post it, and we'll thank my kind sir , now time to attempt to crakc the US z fold 4 balababah
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
What laptop is it? I have a 2006 laptop with a hhd that still didnt fail

Its the dell inspiron 6400, dell used to make really good laptops

If you need a laptop that has no screen/broken screen, get the lenovo ideapad 3/L3, the only problem is the crappy screen
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Mine was bought way back in 1998(i wasn't even in this world at that time), and no parts have been changed ever since, so, yeah...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Rip... I think you should optimise and overclock it at that point... You could install the os through a usb flash drive
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
You aren't really serious about using a Win 98 era machine as a computer, are you?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I really am doing that right now, it has an Intel atom processor 2Gigs if ram, and a 120GB hdd... It might seem like a joke but that is what I use...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I run a modified windows 10 instal which is debloated and use it only for adb and odin... I don't want to overclock a poor Intel atom as it's hot enough already... I do have a usb drive with an OS but it takes 1 Hour to install and 30 minutes after that to reach the desktop... And not to mention, driver installation, which takes more 20 min, add them up and it's a lot of time!

Why dont you use your raspberry pi?
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:

[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
Don't, it's not really that bad, i take proper care of it, so it should last more 5-6 years or so...

Im trying to get a custom firmware for my mk809iv tv box but its too old and no one supports it anymore, if you have a firmware does it support rk3188 and RTL8723BS
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Same
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I don't have it, sadly, all my devices i have are in my signature, so, yeah...
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
Thats ok, it runs but the firmware is trash and always crashes and doesnt even support 2gb ram that comes with it
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
Then it can't be that old. Win 98 machine's RAM was measured in MBs and not GBs and didn't have HDDs that large. I know because I was a computer consultant during that time and worked on many of them. As I recall, it was XP Service Pack 2 before they even supported sata HDDs. It was also a hybrid 16/32 bit and wouldn't run most of todays apps.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
i mean... windows 10 supports 32bit
[Samsung Galaxy Tab A series Guides, News, & Discus] lewmur:
Yes but not 16 which was what 98 ran. The 32bit was only for graphics. 32 bit apps only started with XP. And a 98 machine wouldn't have anywhere near enough RAM even for XP, much less anything later.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
mine was a 2006, which handles win 11 max, but with extreme lag, i use a modified version of win 7 x32 so it would be usable
[Samsung Galaxy Tab A series Guides, News, & Discus] JaneValley:
Here is a tweak to make the brightness adjustment working, if the brightness-fix zip doesn't work.

MAGISK ROOT ONLY

Create a folder in data/adb/modules, naming whatever you want, then create a service.sh file in the folder you created.

Open service.sh, and put this line in here, then save.

echo 100 > /sys/class/backlight/panel0-backlight/brightness

And boom, you are good to go.

Each time you reboot, the service.sh will auto run itself and make the brightness adjustable.

Or, you can just run this command in Terminal, noted that you need to manually do this on each reboot

Hello!

Flashed LOS 19.1 GSI through this guide couple days ago on my T505 model. So, for now i got some problems with this ROM:

1) Portrait orientation by default. Autorotate works well, but still. It's annoying a bit for me when u unlock device and it is always in portrait mode.

2) Hall sensor doesn't work at all. I mean flip case cover with magnet to lock\unlock your device.

3) Screen brightness. Fix makes slider a bit wider as I see, but regulation is so irregular (only 60% of slider length works). Also there is no autobrightness at all, so sad.

Is there any solution or another GSI ROM with gapps without this bugs?

P.S 4 speakers work by default, MTP and Sdcard too. Mobile Network is not tested yet.
[Samsung Galaxy Tab A series Guides, News, & Discus] ljgjm:
I reccomend using pixel experienceto fix the lag issues, and i have the same portraid lock screen issue. Looking for a rom w/out gaps that support normal cpu clock speeds and tablet 100%
[Samsung Galaxy Tab A series Guides, News, & Discus] Diutcid:
Hi, I recently bought a used SM-T500 which has the Android 12 build from Samsung pre-installed (T500XXS4CVJ1), One UI v4.1.

Can I use the method in the OP to install LineageOS (Android 13) on this device?

Reading across these forums it seems like the stock build version that I start with matters and must match the recovery and custom ROM that I am about to install. Is this correct?

EDIT: One more question:

In the flashing steps in post #1, in step 2 is patching the AP file using Magisk:

Should I use vanilla Magisk for this, or the Magisk Delta Canary build that is used later?

Thanks, and awesome work!

hello, this is arrowos spark os crdroid, in short, except pixel and aosp and lineageos, no gsi is booting for me, how can I solve the problem sm-t500 and sm-t507

I'm using the latest version of one ui 4 right now
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbas 2:
is there a way to run one ui 5 nippon gsi in this
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I tried it, it boots, but it shows a "SSM warning" stays on for 30seconds and then infinitely bootloops, don't use it...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I think it's the Samsung vendor that's the culprit, the gsis you mentioned have been heavily weighted on for maximum compatibility, so, yeah, just try everything, whatever runs, runs, if it doesn't, leave it, and also be sure to have selinux permissive while trying new gsis...
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbas 2:
thanks for your help we need to assign a vendor port for this gsi or we need to edit the gsi and I wonder if there is a twrp flash that can solve this problem
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbaş:
If we make miui gsi samsung compatible and install it, will it work and how can we do it?

hello, can you name this topic not sm-t505 but sm-t500 sm-t505 and sm-t507 because all of these devices are compatible with each other and they are the same.

What exactly does permissiver v5 do? is it a selinux fixer?

hello, is there a way to make the system size 5.2gb, the product makes it a maximum of 4.5gb
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
A vendor modified for GSI is needed, but I don't know how to go about making it, and either way, this guide is based mostly on stuff that's already available to everyone, I've just put them together at one place for the user's convenience...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
It will work, but I do not have the knowledge on how to do it...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I sadly can't, as I only have the t505 variant, and it'll be misleading when something doesn't line up in the other devices...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
It changes selinux to permissive, that's all, it's a security concern (usually), but we don't want selinux denials to spam the logs and use up the precious battery...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
No, some other partition has to be deleted to do so, but I don't recommend deleting anything else other than product, as we're working with a Samsung device, and a hardbrick could render the device unusable...
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
None that I know of, as I said once, it boots once, stays on for a little while, and bootloops indefinitely, if you find some way, please let us know, one ui 5 would be nice to have on this device, as one ui has some unique features...

hello, if I return to android 11 and flash sm-t500 kernel, will one ui 5 boot problem be solved?

I'm using sm-t507 and all the instructions you said don't cause any problems are in both. sm-t500 is no different from this device, the only difference is that there is no sim card, they are the same, I have experience, there is no difference in the version
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I'm not sure on that, all i can say is, there's a high chance of it not working,as, we need a proper vendor that has all the HALs, which the Samsung vendor doesn't have all of those
[Samsung Galaxy Tab A series Guides, News, & Discus] Hausemaster:
I've read on other posts that after installing gsis wifi breaks sometimes(sm-t505), I'll still as a note that it will probably work on this variants as well!
[Samsung Galaxy Tab A series Guides, News, & Discus] ismail demirbaş:
I created a topic for those who use sm-t507, nobody gives information on the internet, and for those who do not know gsi, I wrote the title of custom rom next to it, it is gsi rom in parentheses. I learned whether it exists or not, I have already added a few articles to direct you to your topic, the aim is to spread the information to more people.

Link : https://xdaforums.com/t/sm-t507-sm-...e-it-for-those-who-dont-know-gsi-rom.4536025/

and nippon gsi android 11 still doesn't work. Is there a way to port vendor? Google tells it a bit complicated. According to me, the source of these problems is not only vendor, but the system is A/b, but it is actually A only, but somehow they made it A/b compatible. we need to port, no one is giving any information, do you know a little bit about this, maybe I can try porting

Also, for those of us who don't need root, do we need to use magisk? Is the Magisk AP patching for obtaining root and the recovery/dynapatch/kernel for getting the GSI up and running?

I initially tried to flash recovery by first flashing vbmeta but it ended up in a softlock, the process went smoothly on the magisk patched way...

So, to put it simply, I first tried the non root way which didn't work out for me so I stuck to patching using magisk, but do try it without root, it'll be interesting if it works for you...

Magisk isn't mandatory for recovery, kernel or dynapatch.... So all in all, if you can get recovery installed at flashing vbmeta first, then you don't need magisk...
