SM-T350 Android 11 flickering issues - Samsung Galaxy Tab A series Questions & Answers

I have a Tab 8.0 SM-T350 that is running the latest TWRP from NubianPrince and am running his CRDroid android 10 ROM. Whether I dirty flash, clean flash, and even format, I cannot fix the screen from glitching/flashing on any Android 11 ROM. I have tried multiple GAPPS packages, but to no avail. Any help/thoughts are greatly appreciated.

were you able to fix this - I have same thing

Lineage OS stuck on boot animation

I attempted to reinstall the stock rom on my rooted XT1580 Moto X Force from LineageOS 14.1 using this guide below so I could install the Android 7.0 update
released by Motorola which was released a few months ago.
http://www.stechguide.com/update-moto-x-force-to-android-nougat/
After finding that the internet wouldn't work (as I couldn't flash NON-HLOS.bin for some reason and now it says baseband not found in fastboot)
I reinstalled TWRP recovery and tried to download and flash the latest LineageOS rom from the same place I got my old LineageOS zip:
https://forum.xda-developers.com/droid-turbo-2/development/rom-cyanogenmod-14-1-kinzie-t3536148
except now, it won't get past the boot animation screen. I left it to boot overnight and it was still stuck the next morning. (I can still access bootloader and TWRP recovery of course). Same case when restoring a backup
I even tried flashing CM13. Same issue with the internet.
Any help would be greatly appreciated!
Did you ever figure out how to get this fixed? Thanks!
you gotta reinstall LineAge OS from a MM rom, the Nougat files won't work with the LineAge ones...

Problem with TWRP, boot, stock ROM and custom ROM

So, to begin with, yesterday Mi A1 got the Android 9 update. As I always do, I went to uptade it with Magisk (it worked with 8.0 to 8.1 and with every security patch, so I, as a newbie, thought, "why the h3ll not?"). Obviously, it didn't work and I got into a boot loop. So, here are the [lot] of things I have tried to do.
-Downloaded MiFlash and the latest OS version from Xiaomi site (8.1 witch november patch). Tried flashing a lot of times, I always get the boot loop after installing it. Wiped all data with TWRP and still didn't work. Always the same problem. Tried with with march security patch and it actually boots. But if I try to uptade via Settings or flash the newest room, I get stuck again.
-Downloaded latest AOSP ROM for the device, flashed it, wiped cache and data, instaled TWRP (3.2.3-0), but the system never initiates. It freezes in the boot animation and nothing happens.
-I've tried the same thing with Lineage 15.1 as well. Checked with MD5 in both roms. Doesn't work at all. Followed every tutorial I could, step by step, don't know what I'm doing wrong.
Can any one please help me? I don't know what to do anymore. Don't wanna get stuck in 8.0 either.
Also, if someone could .zip the Pie update, I would apreciate that. Could try that
Here's the latest flashable pie for you:
https://drive.google.com/file/d/1q9O_F-TB4l3yWthYjw4jkL2prWfh7ClQ/view
Fastboot boot into twrp and clean flash the above latest rom and everything will be fine

It worked and it didn't at the same time. The boot animation doesn't freeze anymore, but it's stuck in an infinite loading screen
EDIT: Nevermind, it worked in a second flash. Thank you again

Trouble flashing roms sm t350

Hello all, maybe you can help...
After finally getting a stable TWRP from @ashyx that finally booted, I attempted to flash roms and Gapps on my SM-T350. This should be simple enough, but every rom I flash either doesn't boot or boots with only sound and no display!!!!
Yes, I'm running TWRP 3.2.3-1 courtesy of @ashyx
Yes, I've wiped several times.... wiped internal storage sometimes too
I'm running the latest official 7.1.1 release from Samsung.... I cannot get anything else to boot!
Please offer some support, I need some help y'all!
-------------------------------------------
EDIT: THIS ISSUE HAS BEEN SOLVED
Check the latest comments for more info
I'm having the exact same issues, never experienced this before with any device. Hope someone can help or we can find a fix.
Same - SM-T350
I was able to install Jazzrom but none of the other SM-T350 roms. I can hear sound when I press the power button, but no display when trying Lineage 15 or 16. Jazzrom runs slow, that is why I'm not sticking with it. I have tried several versions of TWRP as well. 3.2.3-1 seems to be the only one that got Jazzrom installed. Thanks in advance for your time. Same issue with crDroid rom ver 5.2
my suggestion would be to use odin to reflash to stock, and reinstall twrp. i've never encountered that specific issue with the device

Tried that.... no luck. Everyone else who reported a problem is having the same exact issue as me.... it's strange.
Here is what I posted in the crDroid area:
I might be posting a little soon but finally on the road to success after only getting a blank screen after boot. Downgraded the stock 7.1.1 to marshmallow T350XXU1BPK1 using the BL, AP and CSC files in Odin. Used TWRP TWRP-3.2.1-lineage-15.1_j1_20180418_gt58wifi. Versions of TWRP that worked before didn't work after the downgrade. Installed April 9th crDroid ROM and gapps pico. I am now at the sign in screen.

This solved it!!! Finally!!! For clarification, anyone who is having this issue must downgrade to stock Marshamallow (BPK1) and flash twrp 3.2.1. It must have something to do with the newer oreo bootloader, so just downgrade and Viola! Success! :good:

Stuck at bootloader--HELP!

Let's get this out of the way. I don't have much experience flashing ROMs. I've done it on a few phones, but I can't say I really understood what I was doing. I'm just good at following directions. So, I know about enough to get into trouble.
And ...I've gotten into trouble. My goal is to install LineageOS on my brother's Essential Phone. Based on directions I found here, I determined the active slot was b, so I installed TWRP on slot a. TWRP worked in recovery, but without touch. I then flashed twrp-3.2.3-0-mata.img to the non-active slot. Lastly, I sideloaded twrp-installer-mata-3.2.3-0.zip. I then changed the active slot back to b and rebooted. It now boots only to the bootloader and not to the OS. No matter what option I select--Start, Bootloader, Recovery--it reboots to the bootloader.
Any help to get out of this would be greatly appreciated.
Lineage can be installed more easily using Lineage's own Recovery rather than using TWRP. The Lineage Recovery is a pre-built replacement for your boot.img file.

Thanks for the suggestion. I had actually already tried that. That's when I got desperate and tried generic TWRP. When I try to flash the Lineage recovery image I get a "No such partition" error, no matter which partition is active. I read somewhere that the flash boot_[letter] command might work, but I get "Couldn't parse partition size '0x'.

Try:
Fastboot flash:raw boot_slot recovery.img
So, I found a solution. In order to overcome the errors I was getting, I had to use the raw command. So it was fastboot flash:raw boot [image file]. Once Lineage recovery was installed, I could boot to recovery and sideload Lineage.

I guess our replies crossed. At any rate, the raw command did the trick. Thanks for your help.
I'm having the same problem, and the raw command doesn't seem to help. Trying to install twrp causes it to be stuck in the bootloader. I somehow was able to install the lineage recovery, then to install the lineage OS. Because I am thinking of trying other ROMs, I decided to go back to trying the TWRP install. Now everything seems broken. When I use the a slot (where I installed TWRP), I'm stuck in the bootloader. When I shift to the b slot, I'm stuck on the Lineage splash page.
(By the way, while I was in the Lineage recovery at some point in the middle of all this, I also sideloaded the TWRP install zip.)
I've tried flashing the TWRP numerous times, and it always seems to work, but the result still is the same.
Any help would be appreciated.
Edit: I was able to get out of the loop by reflashing the Lineage Recovery, booting into that recovery, then doing a factory wipe. I was able to boot into Lineage. But why can't I successfully install TWRP? Or, I guess, alternately, is it possible to use the Lineage Recovery to flash different ROMs? (Sorry if this goes beyond the scope of the original question.)
Is Lineage using an Android 10 security update after January? January is the last update for Android 10 that TWRP worked with. Once Essential went belly up the TWRP devs just stopped updating when it broke with February security update. Anyway, I just thought I would mention it.

I installed Lineageos directly on the february android stock version. (which is the last one from Essential)
Simply by following the tutorial on the LineageOS website.
Everything worked the first time.
So there is no need to switch back to the January android stock version. The image recovery provided by Lineage works very well.
And for your information LineageOS is updated almost every Monday.
Moreover the developers of the TWRP are not the developers of Essential. Company which closed at the end of February.

I'm of two minds; one is just to go with something stock android-ish, which leads me to Evolution X or Pixel Experience. The other is to cut myself from Google entirely, which leads me to /e/. I'm also looking at Paranoid, just because it looks like it's stable. Any thoughts on any of those?
I had updated Essential to the February update; would that be why TWRP would not successfully install on my phone?
Would that still be true if I had flashed Lineage?

Paranoid Android: What I heard is VoLTE broken, if you enable it, SMS/MMS might not work properly.
Evolution: No update in Android 10 since August, not sure they contine to support Essential phone for Android 11
Pixel Experience: I don't think they Anroid 10 for Essential phone, only official Anroid 9 which is too old
TWRP issue: You need to go back to Jan stock rom before going to any rom if you just flashed LOS
What current stable rom with Nov security update: I'm using crDroid 6.12 (unofficial release but from XDA reliable source)

(S4 GT-i9506) TWRP for Android 13 ?

Hi, so my phone is running Android 13 (LineageOS 20.0) and i have TWRP (3.5.2_9-0) installed, recovery was working before flashing Android 13 but now it wont boot for some reason (stuck on TWRP splash). I think i need an higher version of TWRP. If anyone could help or provide a link it would be really helpful. (Also my phone is currently rooted using Magisk)

LineageOS uses its own recovery. If you wanted to keep TWRP, you should install it in the second step after ROM.zip.

TWRP doesn't need any android to boot as it uses the recovery partition (in case of S4). All it needs is access to the data partition to save the configuration.
