I am having the same problem, sometimes the screen is filled with vertical lines and then fades to white. Only thing that helps is sliding out the keyboard. I think this is due to the faulty flex cable that connects the motherboard and the screen. I have ran some tests when my device was disasembled (but powered on). The screen was working fine, even when i was bending and streching the flex cable, but after asembling it back again, screen glithes continued. I've then reinforced the flex cable connector on the mobo with some rubber pads and electrical tape, and this seems to be almost working :) (screen jerks only happen 2-4 times a week)As Whazoo pointed out, those screen jerks used to appear more often during power intensive tasks, like receiving a call. Probably this is due to the loose cable connection. Less power than needed is flowing through the circuits and this causes the sreen to "crash".

BTW I have T-Mobile MDA

[8125, K-JAM, P4300, MDA Vario General] Bebob_NL:
I've had the same issues. I suspect faulty hardware. Do you guys experience "dancing" pixels short before a WSOD? Those dancing pixels can be overcome when applying sufficient pressure to the bottom of the phone. I personally suspect a worn flatcable between motherboard en LCD unit which fails to make a solid connection between both. I have to mention that I too have jump started a "dead" battery once. WSOD problems started occurring several moths after. I doubt it is linked.

Currently, the phone is stuck in bootloader, being unable to flash a new ROM on to it since it keeps on rebooting itself every few seconds to minutes. I guess it is a total loss. The phone lasted only a few months when the stylus started to drop out and it took only 16 months before the dreaded WSOD started. At first only a couple of times a week while increasing after a few weeks. I recon a motherboard transplant could fix the problem.
[8125, K-JAM, P4300, MDA Vario General] PTG:
Hi,

got the same problem. And i have also "dancing" pixels, the screen seems to "flicker"
[8125, K-JAM, P4300, MDA Vario General] Whazoo:
oh dear!

I'l have to see if this is a simple flex cable issue. Of course I had just convinced the wife the MDA I have was a hopeless case. I replaced it this week with an 8925 off eBay that I unlocked and flashed to the HTC WWE for Kaiser. BTW, the Kaiser/8925 is a nice upgrade. So, I'll take apart the old phone and see if I can get it working. If so, I'll keep it for a backup.

One question I have is why does it seem to be related to radio usage and battery drain/short life.
[8125, K-JAM, P4300, MDA Vario General] tzunlee:
mine begun after changed 2.21.0olip

flashing bluring and reboting.

i´m trying find a original rom to see if fix it...

----------------------------------------- xx ------------------------------- xx --------------------------------------

7 days trying fix it....

My friend was think a batery problem... He buyed a new one and used the original rom on that. The defect not desapear. The screen still blur, flashing, and the batery begin to warm up to fast, one day the batery was near blow... the batery was too fat, like a pig near christmas!

He give me the Wiza200, I find a used batery, thats work for 4 days and begin to warm up, the celular was draining to fast, and the batery warm up to fasssssst tooo. after 2 days its just no signal...

Take of batery, wait 50 minutes on charging. Turning on, reboot, reboot, reboot, reset, then it begin to be normal, after 5 minutes, no signal, and flashing and bluring the screen and itelf reboot and lock on boot screen... Anoyed i used a ATX pc power suply direct on + and - contacts, soldered some capacitors on main board and same problem. Its draining near 500ma... with sim card its work fine. i can use the games for near 20 minutes, no blur screen just reseting. I take voltages near the processor and radio and sim card suply its almost stable... variation of 10mVolts - 50mVolt... I changed the capacitors for new ones... The mobile begin to be more estable, but bluring and rebooting when put the sim card, reseting near 4 - 5 times on windows... and be estable again... but no signal.

I made a full rom backup, radio etc... tryed to change ROM... nothing change, then I tryied change radio... used the hardcpl.... sucefull changed the radio and the the ipl and cpl.... puff its just reseting and reseting again... Just dont reseting when on it was on bot block screen. I lose time searching a original ROM... My friend send me last rom used... all software back to original and the problem.... Damn...

This device was used near a beach for 2 years...

Unescrewed, again open the case... lift the shields.... clean... clean and clean... this device stoped to reboot, but no signal... wi fi useful, windows ok... used it for 2 days with no problem... when its locked up, and i reset it... Damn dont turn on, just on boot screen, and blur and flash screen and reboot itself near 3 seconds...

I lose my mind. I dissasembled all, put all things on water and a little of a soap, washed all device... for 30 minutes.

Wow. its turn on again......!!!! And COOOOOOOOOOOOOOOOOOOOOOOOOlllll no more drain the batery!!!!!! Excelent signal and im using the fone! 40 minutes and its normal... y go to street, receive some calls and its alive!!!!

Resume: 90% of hardare celular problems is sweat of hands, just need clean.

I hope help someone with it
[8125, K-JAM, P4300, MDA Vario General] mr.incredible:
Same prob a year ago.

I had the same problem a year ago. Sorry to say I never found a solution. I ended up buying another used one from eBay. ROMs won't help I flash my phones a lot looking for the perfect combination. I think you are on the right track with the connector between the display and MB. I think it has to do with condensation and heat. Explains why heavier powered use causes the problem. The more battery drain, the more internal heat. When I finally gave up on mine, It wouldn't boot anymore. Actually it does boot and everything is working. I've even received calls with the screen white. I picked it up a couple months ago, tinkering with it. I put a fresh battery in and it booted up and lasted about 10 min. I was excited for a while thinking time had fixed it. Bummer. Good luck. I hope you find your solution.

i've been experiencing vertical lines & flicker with my tmobile mda especially within the submenus. found out that by lowering the overclock (omapclock) to a value near its default clock speed, the problems disappear. i'm guessing it might be related to overclocking my gadget.

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] googlephoneFKLenAsh:
I see there is no correct/clear instructions on how to update firmware when you already rooted your tablet without losing data.

Many people, including myself, are forced to factory reset by following wrong instructions floating around.

So I think it is necessary to post a clear guide on how to update with root without losing data.

There are two correct ways, and the key is never flash stock AP without patching vbmeta at the same time. Never let the stock vbmeta.img flash to your device. The stock vbmeta.img in stock AP will enable Android verified boot and will lead to factory reset in the next boot.

First and preferred method:

1. use magisk to patch the whole AP file and magisk will patch both boot.img and vbmeta.img.

2. Flash magisk patched AP in AP slot and BL in BL slot and HOME_CSC in CSC slot, and done.

Second method:

1. Download vbmeta_disabled.tar from https://xdaforums.com/t/how-to-exynos-snapdragon-root-s20-series-and-upgrade-firmware.4079353/

2. Patch boot.img using magisk: extract boot.img.lz4 from stock AP, compress it to a tar file and patch the tar file in magisk.

3. Uncheck auto reboot in ODIN, flash stock AP in AP, BL in BL and HOME_CSC in CSC slot, and vbmeta_disabled.tar in USERDATA slot at the same time. With the vbmeta_disabled.tar, Android verified boot remains disabled. Remember to flash them at the same time in ODIN so that Android verified boot remains disabled. If you flash vbmeta_disabled.tar after flashing stock AP, Android verified boot will be re-enabled and it will ask for factory reset.

4. Check auto reboot in ODIN, flash magisk patched boot.img in AP slot.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Skidoo03:
When you're using the preferred method to patch the AP file, are you just using a tool such as the Samsung Firmware Downloader to get the zip and then extracting that into the 4 .tar.md5 files? If so, how are you patching the AP .tar.md5 file with Magisk? It fails for me when I attempt it
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] googlephoneFKLenAsh:
I used Frija to download but it shouldn't matter where/how you download the firmware as soon as it's the correct firmware.

Just use magisk to patch the AP .tar.md5 file. You should see in the magisk patch log saying patching both vbmeta.img and boot.img.

It shouldn't fail if you are using latest magisk canary.

Any error message in magisk when you patch the AP?
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] joecaesar:
Thank you for the guide. Still haven't tried but cleared some doubts. I even thought of restoring and relocking bootloader. Will update my result after trying the preferred method.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] joecaesar:
Method 1 works like charm.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] umibuzu:
I didn’t update since one year. I was on UI 3 and android 11. I was not sure at all to succeed but it worked. Updated with no data lost.

Don’t forget to patch the all AP file before with the last magisk (25.1 for me). Then, use the patched file instead of the original AP.

Use the "Home" CSC.

Magisk can need a reboot before de wake up

Hi there,

is it possible to patch all 4 files (incl. patched AP) at once?

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] nakamiro:
I am not sure, but I did it like this, I hope it helps.

The resources/drivers/programs I used can be found at the bottom of this comment.

Firmware Upgrade Guide Samsung Galaxy Tab S7+ | SM-T970 | CSC:EUX | while keeping/retaining Magisk Root.

1.Download Latest firmware on PC via Frija (CSC:EUX & Model:SM-T970 for me)

2.Extract ZIP Open extracted directory and delete ZIP.(I like to keep a clean overview, so optional)

3.In the directory you find BL, AP, CP, CSC & HOME_CSC files. If you use the Wifi only version of the Tablet, you can remove the CP file.

This leaves the BL file (should be left untouched), AP file & CSC & HOME_CSC files.

Choose one of the two CSC files to keep.

4.a. Want to Keep your data? Use Home_CSC....tar.md5 file using ODIN, other file can be removed.

4.b. Factory reset? Use other CSC file instead.

5.Move (not copy, but move) AP file (AP......tar.md5) to Tablet and patch whole file in Magisk (I am using the latest Canary Magisk version)

When this is done, move the patched AP file called magisk_patchedsomethingsomething back to the first extracted directory (step 2) AP-file name does not matter.

Connect tablet to PC with USB.

Using Terminal in ADB directory, use " adb devices" to check if PC can find tablet when tablet operates normally. Use command " adb reboot download" to boot the tablet directly into download mode.

Open ODIN (no settings need to be adjusted in ODIN other than selecting the correct files)

In ODIN,

Select AP ---select ---> magisk_patched.#######.tar

Select BL ---> BL_####.tar.md5

Select CSC ---> HOME_CSC_####.tar.md5

OR use CSC_####.tar.md5 if factory reset is required

Click Start. Wait. And enjoy!

Resources used:

-Friji v1.4.4 for downloading latest firmware real fast.

-Minimal ADB Fastboot v1.4.3.exe for minimalistic ADB-installation

-Samsung USB Driver for Mobile Phones (for PC to recognize the tablet in Download mode)

-Odin (I used the latest version v3.14.4)

Patch whole AP take times, my device is ramdisk + no vbmeta so i just patch boot.img

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Drahy:
Hello,

I tried the first method but it still said vbmeta error and I had to reset all data...

I was using stock Magisk 25.2 version. Before I do it again after some months...

1) I know I have to use Canary now is there any specific version to have?

2) Is there any verification that vbmeta was really patched? In both versions of Magisk (stock and Canary) it always said in logs "patching vbmeta..." so how can I know it really happened?

3) Can I patch whole AP from stock firmware and just extract already patched boot img from that AP in the second option? Not to extract boot.img and patch only that file separately?

4) To be safe can I combine both options? Using patched AP from option 1 and use vbmeta disabled in option 2 in USERDATA?

Thank you!

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] onelly23:
The first method doesn't work for SM-A53 5G devices, i followed it exactly and didnt work. It prompted me to format the device, which means the vbmeta wasnt patched, even tho magisk said it was. Thank goodness i had backup before i tried it. Anyway i updated using the harder and longer way.

I'll try the other option next time.

i am clueless to this whole android thing..ive read all the threads and im still :confused:

is it possible that some one can write a step by step guide as to how to install the RC30 patched update...

im dieing to get it and ive pretty much gona cross eyed from all these forums...i justy cant seem to figure it out..

thanx in advance
[G1 Android Development] humble:
First you must Flash JesusFreke special signed recovery

Things you need to have and do

the debugging drivers,Android SDK, AndroidMod

(You must do it through adb shell so you need 32-bit OS)

Put your device into USB debugging mode(thats in settings/applications/development)

Connect your device with your PC

When it asks for driver location (were you put it)

You'll see sth like "HTC Dream Composite ADB Interface" on success

the drivers are in the attachments

to download Android sdk go here http://code.google.com/android/download.html

and Androidmod here http://xdaforums.com/showthread.php?t=443041

ALL WITHOUT THESE""

AT the root of your hard drive put AndroidMod folder ex."C:\Androidmod"

and from the sdk copy "adb.exe" and "AdbWinApi.dll"(it's in tools) and put them in there.(C:\Androidmod)

Now go to run and type "cmd", now when the command prompt pops up navigate to "C:\Androidmod" by doing

"cd C:\Androidmod"

Once your in there type "adb shell" then

"mount -o rw,remount -t yaffs2 /dev/block/mtdblock2 /system"

"cd /system"

"cat /data/local/recovery.img > recovery.img"

"flash_image recovery recovery.img"

"reboot"

Tada how do you feel?:D

To check if this was done properly hold "HOME" and "Power" to get in to the recovery Menu

when you do press "Alt + L" it should say "using test keys"

Now that thats out of the way the easy part comes

download JesusFreke Modified RC30 - full version rename it to update it should look like this "update.zip"

put that on to the root of your sdcard

Restart your device holding "HOME" and "Power" to get in to the recovery Menu, when you do, press "Alt + L" read and then press "Alt + S"

tell me how it went

I think the whole point is root.

I'm new but I think rootseems to give programmers the ability to do whatever they want to their phones. Kind of like a puppet and gives more freedom to do innovative and creative apps and other programs and not have someone cap their enthusiasm about "open" platform google is always ranting and raving about.

Also, everyone thank JesusFreke for being the great helper and hardworking guy he is to help us all out who are not as knowledgeable about the entire process.

You need to disable the OTA Update app.

Use a adb edit or a package disabler.

Your carrier can disable it from their side as well.

Stay away from wifi networks until this is done. The carrier may also have update towers which update very fast if you get in range.
