Recently I received my cousins Note 10+ 5G and was cleaning it up. I deleted an app called Magisk (Which I later found out was some kind of ROM?? or something like that) After opening the app and pressing uninstall my phone shut down after a few seconds. after I powered it back on, it goes to Samsung recovery. My cousin said I should reinstall Magisk, but the phone won't work. I have even factory reset from Recovery mode. Even if I force shut down and then power on, it goes to the "Hello, Select your language. Connect to a Network" like you would normally get from a new device. After about 15 seconds it powers back off. I have read that I should flash the Stock ROM using Odin, but I have no experience in Phone technology whatsoever. I would appreciate any help or guidance on how to fix it. Thanks,

Ok so I'm not a noob around here. I'm pretty good with the android stuff, but this one has got me stumped. I have a perfectly working sidekick 4g with B2b 2.5 on here. All of a sudden it forces itself into a repeated reboot. It shows me the white sidekick/samsung screen, and about 3 seconds later reboot into the same thing. And it does this over, and over, and over again. At some point it stops and functions normally, but only for a few minutes, then repeats the process. I've already changed roms, back to glorious overdose. It will even reboot in CWM. The only time it stays stable is when it's in download mode. Another problem there. ODIN doesn't recognize when the sidekick is plugged in through USB. So even if I wanted to ODIN, I can't. I tried booting without my sd card, and my sim card. No avail. and i disabled lagfix, still reboots. I take the battery out, and when I put it back in, it turns itself on just so it can continue restarting. There's nothing stopping this phone. Please help if you can. Thanks for taking the time to read this!
first, enable voodoo. i tried disabling voodoo once and it just kept rebooting. i pulled the battery, put it back in, enabled voodoo, and it booted normally. however, in your case, i would run fix permissions before trying to reboot. to run fix permissions, while in recovery mode go to advanced. select fix permissions, wait for it to say done, hit the back button, and reboot. see if that helps. if not, you may want to ask someone more experienced.
Thanks for your reply. I found out that my windows(8) didn't correctly install my sidekick drivers. tried it on my xp machine and bam, ODIN worked like a charm. Unfortunantly, the problem persisted. So i know it's not a software problem. I contacted samsung yesterday and sent in my phone today. I ODINed back to stock then updated to kj1 through kies. I read up on it a little more and people said it was maybe a loose connection on the phone. I'm still in warranty, so I'll let samsung deal with that.
Need suggestions for this.
A few weeks ago I rooted my phone to remove some apps that I never used. I just kept using my phone as always and did nothing special except removing those apps. Today I decided to unroot my phone because I felt it would be safer in case anything should happen to it (HOW IRONIC). It's only 3 months old and I didn't want to loose my warranty. I opened the SuperUser app and clicked full unroot and clicked continue. My phone instantly returned to the home screen and then powered off. Then it turned on again, but now the message "Samsung Galaxy S7 powered by Android" keeps flashing on the screen. I went into recovery mode and tried wiping the cache first, but nothing changed. Then I wiped all my data and did a factory reset, but my phone keeps flashing and won't turn on. I'm really desperate and don't know what to do because I'm afraid I can't take it to my retailer because my phone is rooted (if it still is rooted, but I have no idea). What should I do?

Hi mate
I would reflash again with odin using home csc instead of CSC so you do not loose your data and settings......
Edit : once it has been rooted the knox bit is set , there is no way back
I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
Hi, it is an older device so you might have experienced everything possible.. so,
After a long time of trying to fix that phones mind, I wiped everything avaible in TWRP
multiple times(got mad). Last thing was data.
That way I went from a bootloop to an active nothing.
Phone does not react to any command, it does not react to USB charging or on PC.
That's the case a few months back, the phone halfway in the trash and I bought
myself a iphone (hate it).
I put the Galaxy S7 on a charger today and it starts immediatly in to TWRP.
From there I tried to install a ROM that's left on the SD card, which forced
a restart into TWRP. Into download mode I managed to install the stock Oreo ROM via Odin.
It went through like a charme, all green. PASS!
The phones screen is black and does not react to any command, nothing.
I had "auto-reboot" activated.
The phone is active it's warm and I'm waiting for the battery to die again, to restart.
..meanwhile,
Can you give some advice please?
Why would the phone have struggle with the boot with stock rom installed.(which has worked before,no updates installed)
When should I install TWRP?
When do I install what kernel?
Last thing running was the LightROM with moro kernel with nothing tweaked.
Also. The issue why i deaded the phone was a camera/flash thing, where I could only take pictures with flash activated.
Front and back camera. On all camera apps, I couldnt scan my ID for banking due to that.
Also on different kernels and different ROMs including the Samsung stock.
Why would that be
Could not accept...

OK so what you've done is correct flashing stock (which includes stock kernal). You have to make sure the stock ROM is correct for your device and region or it will not start.
It's not unusual to have to flash it twice with Odin.
Next up you don't need to wait for batt to die to restart. Press volume down+home+power and keep them pressed until phone restarts. Should now be in download mode, reflash correct ROM with Odin. TWRP is wiped off the phone when you flash a stock ROM.
If it doesn't go through the boot up/freezes/ does nothing etc. You need to "wipe cache" then reboot from the recovery menu.
Press and hold volume down+home+power. As soon as the screen goes black move your finger to volume up (it may take more than one attempt). Once your in recovery menu use volume up and down to move through options and power to execute. Wipe cache then reboot and allow the phone to go through all the reboot stuff. It can take a few minutes just leave it alone. It will also reboot a couple of times.
If it does nothing after 15 minutes then start again and repeat the process.
Thanks for reply.
The Phone was off for a day and after charging for 1h it still does not react to any command. Vol down + home + power does nothing. Same with vol up.
Is there a way to force a boot? Even if the PC does not recognize a device on usb?
I Tried the commands 30 secs each, plugged in and off. Also usb port is not broke since the phone is getting temperature after a while charging..
