HELP - Stuck with black bars - Samsung Galaxy A51 Questions & Answers

I was just trying this open source app, which required enabling USB debugging and then it apparently changed the resolution and now I'm stuck with black bars like this:

The issue has been mentioned before here and was solved, but the fix is not working for me. I've already opened another issue over on github, but I'm quite worried I ****ed up my phone and I'm looking for any fix I can find.
Any help is appreciated. Thanks.
EDIT: I managed to change it back via adb shell. Here's a link for whoever goes through this: https://nerdschalk.com/change-screen-resolution-adb-android/

Issues accessing usb diagnostic mode in Lollipop/cm12/pa

Ok, after searching quite a bit, there doesn't seem to be any way of configuring usb diagnostic mode (sys.usb.config diag,adb) in CM12/PA 5.0.2. I've tried several times, and the closest I get is adb working and the diag port either constantly turns on and off, or doesn't read at all. I'm thinking it might be due to the fact that I can't seem to fully shut off mtp in storage. It only turns off (meaning the screen to switch doesn't open) after I issue the diag,adb command. I'm not sure, but I'm leaning towards this being some sort of new setting for Lollipop, which, if so, I guess I can try writing a script that might allow diag access. But, if anyone has any insight into this, please let me know. Thanks for reading.

Shameless bump is shameless. For shame...
Hello, did you find something out?
I'm looking for a solution too. I think we are screwed until there is an OS update that fixes it

hi guys...
any news from diag mode for CM12..?

Issues with Android Control

I'm trying to get AndroidControl working, because my screen and digitalizer is broken on my XT907. The issue I'm running into, is that AndroidControl never recognizes the device.
Running through the cmd, adb devices doesn't list it, so it's not picking it up. I understand that adb must be enabled on the phone, but can't find a way to do this, since the screen is broken. Every fix or workaround involves some other program or action that requires seeing the screen or having touchscreen capabilities, which I obviously don't have.
Is there anything I can do to get this taken care of ? Neither my roommate nor I can find anything that works. Please help!

New Verizon Ellipsis 10 Tablet

I purchased the new Verizon Ellipsis 10 in late November. I believe the tablet was released for sale in mid November. My question is can it be rooted? I see the Ellipsis 7 and 8 can rooted. Wondering if anyone would be working on this or because it from Verizon no one cares. I can't find the tablet mentioned on any search that I do. I Have been checking daily to see if the device will have development on it. Thanks in advance for any information.
In the same boat. Need some help you smart tech guys out there. How can I root my Ellipsis 10?
I have the same tablet, and I do not think it could be rooted, at least not in the near future. The tablet comes encrypted (which I am not too happy about....I just noticed it) and cannot be decrypted, even if you do a factory reset. It runs fine as it is, but would be greatly enhanced if it could be decrypted. I also think there are very few devs on this forum that really care a lot about this tablet, so you may not see too much work being done on it.
Same here, just picked one up. Really hoping that there will be a root for this at some point soon. Someone please help us all out!
wish I would have saved the 50$ now, and got the Samsung tablet for free... it's OK, the biggest problem for me is the audio output being too quiet. all the "volume booster's" on the play store have been jenky, to say the least. if anyone has suggestions of a "good, volume booster", or work around, please let me know. thank you for you time.
Oh, No! Sadness!

qtair7 firmware files
https: / / " www dropbox com " /s/f8ye7yw24mjqiva/IR7-20C59.7z?dl=0
just fix the text when u enter in address bar (-""'s,+.'s)
so i downloaded the IR7-20C59..7z package from the software upgrade/repair tool from verizon... I extracted the files and sent the boot.img to my tablet (qtair7) and used magisk manager to patch the boot.img then I used ubuntu to adb pull the magisk-patched-boot.img and modded it using abootimg and changed a few things from default.prop.. ro.secure=0 ro.debuggable=1 and drm.service.enabled=false .. (just saying im an amateur android enthusiast with little experience. ive played with image kitchens and compiled a kernel and ported a rom for the samsung on5 indie variant to have sound on my smg550t1. worked but all google services and apps crash constantly.. but anyways) i dont really know what im doing just saying this is what i did. repacked magisk-patched-boot-new.img then i sent the adb reboot fastboot command to my tablet and it fastboot flashing unlock , fastboot flashing unlock boot, fastboot flash boot magisk-patched-boot-new.img. fastboot continue, fastboot reboot.. the tablet boots and is rooted with magisk.. now i installed busybox to sbin. i have done this 2 times. im not sure if its the busybox or the magisk, but when i reboot following the above steps i get the verizon splash screen and in the bottom righthand corner of the screen it says modified. then boots to recovery. and now can only boot to recovery. now i have the upgrade/repair tool .iso on usb flashdrive that i use to repair my device from this state. which sometimes is a pita.. i have to continually attempt to repair sometimes it takes 2 days.. before it finally works.. i dont know why.. but it boots from fastboot the first time fine. and would like to know how to stop the soft bricking of my device or how i can obtain a twrp.img for this device QTAIR7.. please help ive been working on rooting my tablet for over a year. and feel that i am very close . thanx
Anyone interested in the system.img or any other partitions.. the Dropbox file is only the recovery flash files. I think. I know I couldn't edit system.img from the file with any kitchen but the system.img I dd'd from my device can be edited with kitchen. It's is 3.7gb so in not going to post unless someone can do something with them
Please share some info on the file you posted,..

Hello, THANK YOU!! This is the most progress I have made in months! I don't know what it is, what it offers, or what to do with it yet, but it is a step!
Could you maybe say what it is, what it will do (how it helps..) and what to do with it?
My Verizon Ellipsis 10 (qtair7), even after wiping the cache, even after doing a factory reset, (even after 'disabling' all but FEW APPS!) JUST SPONTANEOUSLY REBOOTS every time i try to do anything, I try to watch a video it is fine for 5 minutes or an hour then I push volume up or touch the screen and suddenly it reboots, totally random, Clearing the cache gets it to works for a while but it always does it again it has NEVER been usable really,.. It pops up some screen often like"Google Play Services have stopped' something like that,.. Will this help with any of that? Make it more,. stable?
I wish I could just do ANYThING simple to make it better I just use it for video playback,.
THANK YOU!
I have the same tab with the same issues. Rebooting, random cut out and full on reboot. Just before it became target practice I decided to take it apart, just because that's what I do when I'm bored and my ADHD is taking over. I looked up the tab on youtube to see if there was any vids of how to get it apart and found a guy that said he fixed the with the tablet that no one could figure out. Meh I was like ok I'll give him a couple seconds checked it out. He found that all connections, screws holding boards down, and power were all loose. Once he went through all of that it had fixed the issues. So I tried it and damn, everything from screws holding boards down to power feeds were all loose, really bad loose. Got mine working good now. Haven't had issues since. Now if I can get it rooted I'll be good. And I suspect the loose connections would also potentially cause the battery to go bad from excessive amperage draw and charge in short time, over time.

LCD Display got broken - Black Screen how to make a backup of Pictures?

Can I authorise ADB with a broken screen that does not show anything?

Hi all!
Unfortunately, I dropped my OP6 at a gig last night and the screen is decimated, cannot see anything and I cannot interact with it.
I took some photos and videos that I really want to keep but as wifi is off Photos will not back up.
My hope is to switch on wifi using adb, not sure if that is even possible but before I can try this I need to authorise adb on the device, which I cannot do with the screen being in the state it is.
I can see the device when issuing adb devices but of course it tells me it is unauthorised. Is there a way I can authorise adb on this phone to allow me to switch on wifi?
All of the research leads me to solutions where the digitiser is broken but the screen is still visible and the issue is solved using OTG adapter, this solution will not work for me.
Any feedback is very much appreciated!
Thanks!

If you have the developer options already activated and have already used adb with your phone in your computer I think it authorizes automatically.
In my case I don't have to authorize my phone every time.
If you haven't done this I think there aren't much options but to replace the screen
Hi There,
That is my problem, I have not yet used ADB with this device so I had not yet authorsied ADB on the device.
So far I have not uncovered a way of doing this, it looks like I will be losing a lot of photos and videos
