There are no custom roms that are built from source. Those are just modified versions of stock. You most likely won't be able to get it working on stock you will just have to wait. I am trying my best

t111 has no usb host feature. It is only usb client. It means that you can hook the tablet to a computer but you can't plug a usb in to the tablet.
This is about hardware. A rom can not help you on this.

download
sorry... where is the download link?....

Hi guys, does anyone have or care to upload the wallpaper that comes from flashing the custom rom? I didn't removed it, and it simply disappeared when I did a reset.

SM-T116 rom dilemma!!

Good day XDA!! This is my first ever post or thread on XDA, for about 5 years I have been a spectator to this site, and it has been an essential source for all things us android foondies want and need. But for the past month I have hit a blank when it comes to my new tab3 ve 7.0 sm-t116nq (goyave3g).
It started when I wanted to root it, little to no support for this model was available (at least through the search function) I managed to root through Kingo root on a pc. But now my dilemma is finding/porting rooms for this model. I have no problem with all my Mediatek androids, but I'm in the dark when it comes to samsung. I don't even know where to begin, for other popular Samsung's it's not a problem, obviously because they're popular.
SO, I need some help. I hate this abomination they call touchwiz, I want a vanilla aosp rom for this model, or even better CM or PAC-MAN rom!! I am prepaid to put a lot of time and effort into this. I have extremely limited experience, most of my past successes was actually the success of other xda members (you guys are awesome BTW.) Any info would be apriciated.
So let's revive this tablet and let's start a revolution for budget tablets.

pit file
Can anyone help me find pit file for galaxy sm-t116NU??????

OMG, Im also stuck here with SM-T116BU which was officially upgraded to Tab E (somehow) how it happened, i don't know since this was my son's Tab 3v originally.
lately. i have rooted tru inception (nice job for the rooting guys) then tried TWRP 3.1.1.0 but couldnt boot, down ver to TWRP 2.8.7.0 bcos the others are either not TAR for odin or files are missing to boot TWRP recovery.
so far, i have tried CM-13 but failed miserably, perhaps those files are corrupted as well
I enjoyed loading with my "Note3 with touchwiz" DO NOT TRY THIS UNLESS YOU KNOW HOW TO RECOVER, so i tried using the same ROM N9005_TouchWizMM_V4_16-04-2016. installation smoothly with TWRP into TAB E but could NOT make it BOOT.
I guess some files are missing while downloading those as well or those files have been corrupted thru the years.
N9005_TouchWizMM_V4_16-04-2016 not difficult to find but NEED an expert to cook a SM-116 version since this is best "complete" ROM (need kernel) in my Note3 now
I'll keep trying ROM N9005_TouchWizMM_V4_16-04-2016 into THIS TAB E and mixed with SM_116 kernels n I KNOW I MIGHT BRICK THIS SM-116 Tab E, what the HACK so let it be, NO VENTURE NO GAIN hahahaaa

What exactly are you trying to do?

Well. The TouchWiz works perfectly on my note3 so I'll try to cook a TouchWiz for Sm-t116 from the note3 platform. If u have ready ROM, do send them. Tks in advance !
Ps. Out of town next few days ??

Guys please give the firmware rom for TVRP on the TAB-3 Lite SM-T116 ! Cause when I for some reason flashed TVPP I realized that there are no custom firmwares for this device , But I need 100% working FI-WI, and cyanogen mod does not fit, cause Wi-Fi doesn't work there!

Is there more ROMs?

I recently purchased an tab S4 just an update from my previous Samsung tablet. I was wondering is there more ROMs for this tablet or ROMs currently in development? I noticed theres like 2 ROMs for this tablet. I have a note 8 and I'm currently running deluxerom on and it, and I really enjoy the tweaks and customization I'm able to do. I was looking for a same kind of feature for my tablet. Would greatly appreciate the answers I'm looking for. Thanks!

Pretty much zero support. You can get a few 9.0 GSI ROMs to boot, but they all have issues. Mine has been sitting around since it was purchased while still using my old 2014 model.

I had thought the same thing, but it seems the S3 is the last tablet to get real support.
https://forum.xda-developers.com/project-treble/trebleenabled-device-development
Some of the ones for 9 will work, but most features won't work too well, if at all.
You might be able to get another rom to work, I know I had no luck. Even trying ones with similar hardware, they all failed to even flash since the booting numbers are different.
Kind of have to be satisfied with Samsung, half baked custom roms or sell the thing.

Hey Veekay I tried it and you're right unfortunately I came across the same issue as you brother
Now I'm stuck and I need help sorting my device out, was wondering if you knew this issue or could help?
When I got the stock firmware back and then when I flash TWRP with odin after going into TWRP I get 0mb as internal
so when I format and then go back into my load up the screen after SAMSUNG says "verification failed" and then reset
on the bottom. I tried other options as well. Without even wiping on TWRP the devices boots up into the setup wizard for the firmware fine
but after I wipe TWRP so I can get access to my internal drive my samsung boots into that verification reset screen. Got any clue as to how I can
resolve this issue? Thanks a bunch!

Have you tried just reloading the latest stock firmware from scratch?

Yup, its unfortunate that there isn't much community support for this device. The Tab S4 is Project Treble supported and a few GSI ROMS do work. But as others have said they are unstable and not for use as a daily driver. We have a few discussion threads here talking about them.

Would that work? If I did that I would still be able to download and install TWRP and have a root? Because of it being PIE

Generic System Image (GSI) list :
https://github.com/phhusson/treble_experimentations/wiki/Generic-System-Image-(GSI)-list
you can try only "Android 9 Pie" official or unofficial gsi roms..
and remember ! Some GSIs roms maybe are not compatible with some devices! you can ask for your device on each thread
(for example look here): https://github.com/phhusson/treble_experimentations/issues/777
(usually this Gsi aosp 9 phh, generally works on most devices...BUT! ask first,and discuss it in the thread)

Sorry,but I don't understand what do you mean " without stock rom and only twrp"...
you can install a Gsi rom, with two ways
Via TWRP, or Via Fastboot : https://www.xda-developers.com/flash-generic-system-image-project-treble-device/ (Tab S4 is a-only arm64)
for any other question, it is better to ask in the thread : https://forum.xda-developers.com/pr...vice-development/aosp-9-0-phh-treble-t3831915
(read carefully in OP & you can post,every single question there for your device,and you will get certainly help from the developer or from any other user..)

You are going to have to just wipe it and start over from square one, unless you made a TWRP backup before starting all of this.
Download and flash the latest stock rom from recovery and then you can load twrp again.

I was looking at the possibility of using GSI's on some devices, and while they can offer new life to older devices, they're not entirely stable all the time unless you're willing to make your own changes. I know Lineage has made some excellent progress, but it's not fullproof yet and I wouldn't try it unless you're willing to not use your device as a daily use device.
I had an extra T-Mobile Revvlry which is basically a rebranded Moto g7 Play that I installed the Lineage GSI image and it works fairly well. However, this is more the exception to the rule and Moto devices, I feel, are far simpler in design vs certain Samsung devices. It also had a ton of trial and error involved for me to get it up and running properly.

Is it possible as the s4 becomes older, more people buy it and Samsung stops releasing official updates that someone will come along and create a ROM for it? Or is it more like Samsung locked the bootloaders and its close to impossible to write a ROM for it? Is it still possible to root the s4?

Thanks. I took a quick peak at the roms and kernels in the roms and kernels forum and they are pretty much all abandoned.
Someone did mention that the LOS 16.0 and ArrowOS GSI's work alright but are a bit buggy.

samsung,maybe at the end of july to give the upgrade to android 10....it is very likely to happen I think
yes,all Gsi Roms still have various problems unfortunately...
my opinion is: stay to stock rom for now....you can "uninstall" many applications if you want & without root, via "samsung package disabler"(paid) from playstore, or with this way:
https://beebom.com/how-remove-bloatware-android-without-root/
also,you can Install "NiceLock Downloader Companion App" ,to add some features on your device : https://forum.xda-developers.com/galaxy-note-9/themes/nicelock-module-download-links-module-t3923844
with this way I operate my device until now..

Galaxy j6+ Android 10 TWRP and downgrade

Hy,
i, got a Samsung Galaxy j6+ (SM-J610 FN) that was before automatic updatet to Android 10.
So i want use it for me now and want to root and change to a Twrp recovery and any custom Rom.
-----
I had the last years many devices as Sony, HTC, and older Samsung and nevertime i had so much problems to understand and also start to flash Twrp and any rom... Yust now with this device i starting cracy :-(
-----
So the problem to understand proper/my questions (my english isn,t very well):
1. i read now nearly two day,s a lot of treads ther and on other Forums. And i starting realy confused now becaus it seems al lot of problems with newer Android System (and also Bootloader) to flash and permanently root,...
2. as i read: something on Android 10 dont want work (is broken) after Twrp/root or have other problems,...?
3. If the TWRP is flashed with existing Android 10, only Magisk is then flashed (with TRWP or ODIN) not: RMM_BYPASS_V3_CORSICANU.ZIP and not J4 + J6 + _oreo_forced_encryption_disabler.zip. Is that right?
4. So, also i read things about the existing bootloader Version that must be have to do this? I have now U2.
must i have a higher version? So many things make me realy unsure what i have to care bevor i can flash some rom e.g.
###################
So what I had made before (already):
1. Set the device back to factory setting ...
2. unlocked OEM
Then i wanted flash TWRP (and i also try,d to flash stock-Rom first after it not work,...) but everything dont want work about Odin failed e.g....
3. Did I find that the bootloader State Prenormally stood ---> I have now fixed that with date. That should fit now.
############
What i wont to do:
Preferably downgrade to Android 9 (or 8?), as the device with Android 10 is very slow now. :-(
- Flash TWRP
- Flash Magisk (get root)
- Flash Resurrection Remix (vx.x.x.) for Samsung Galaxy J6+
(????BUT I NOT SURE WHITCH ANDOID VERSION IT IS????)
- (or) Flash lineage-17.1-20200318-UNOFFICIAL-j6primelte
(????BUT THIS IS ANDOID VERSION 10 ALSO IS,NT IT ????)
*If there a good stable Version Rom with Android 9 or 8 so where/which,...?
And if i can flash to downgrade must i then flash the files: RMM_BYPASS_V3_CORSICANU.ZIP and J4 + J6 + _oreo_forced_encryption_disabler.zip? And when then in which way?
After TWRP (before Magisk), or after downgrade already,...?

So i have a lot of Questions here, i know, sorry and somewhere it can read part,s of this, but i,m not sure what right for me . :-(
But there many treads now from 2018 til yet and it isn,t easy for me to understand, or better to find the right information's for me in this case (Android 10, downgrade,........ which Rom,....)
I would be very happy if someone can tell me understandable as I have to do exactly and which files are really needed to successfully downgrade with root on Android 9 (or 8?) and maybe even which Rom is recommended. Thanks for the time to have read this here.
Regards, paulhu

As I don't know the version, you can follow this video on YT, I hope it helps you.

Hello @hakli,
many thanks for your response.
Which version do you mean? The Galaxy J6 is: Galaxy SM J610FN / DS.
Thanks for the video, it's certainly very helpful.
What confused me most is with the two files that have to be flashed in a TWRP TREAD stood that it is not needed at Android 10, but there was no feedback from other users and in other places it's about it?
As far as the downgrade is concerned, another thing again ....
Greetings, Paulhu

I will honest with you, it is not easy to install twrp on j6+ (any version) watch every vid on YT. but follow the video and install the stock rom, and there will be a file called , you have to follow and use the magisk app to root the phone. Sorry for the late reply. I am kind a busy.
And I don't know where do you live, if you are an American , Italian or Indian. once I know , then I can embed the video that you can follow, First follow the above video and install the stock rom from sam mobile. You can PM me too.
