[Galaxy S7] Reboot fails on rooted phone - Android Q&A, Help & Troubleshooting

I've encountered a strange problem that i can't seem to find anywhere else. When my phone is rooted and i attempt to reboot it, it gets stuck at the verizon logo. But when it isn't rooted, it reboots perfectly fine. I've found that it was not caused by an existing app in the phone, as a total factory reset of the sdcard (CSC) was not necessary to get it working again.

[Q] Setup problem with Galaxy S6 Edge G925F

Basically after a little play around with my phone I decided to root it using Chainfire, which went absolutely fine. My first problem arose when I tried to flash twrp recovery which led to some weird screen whenever I tried entering recovery. I wanted to factory reset my phone (So I did it through the settings) and now on the phone setup it just sits on the software update screen saying it's checking for updates. Any ideas on how to solve this?
Get odin and reflash your stock rom from sammobile! I did that and keept all my apps and files nothing was gone! Good luck

[Q] Encryption unsuccessful on LG G3 D855 Stock Android 6 Marshmallow

Hi!
I got some major problems with my G3. I was on stock Android 6 (rooted). Worked fine for some months. Then I decided to encrypt the phone and activated this option in the normal android settings. After some time the phone restarted and I got the "Encryption unsucccessful" page and cannot do anything anymore.
After reading through the help forums I tried the following steps to solve it:
- factory reset
- wipe eveything in twrp and flashed system, boot, modem manually to Android 6 again
- repaired all filesystem partitions in twrp
- many many more factory resets
All didn't help. The only thing that changed is that when coming to the "Encryption unsucccessful" page now the phone hangs up after the next option I choose (shut down or restart or factory reset) so I have to take out the battery to restart or shut down.
Any suggestions how to solve it and maybe also any suggestions what might have gone wrong? Don't want to kill the next phone the same way by just enabling encryption!?

Galaxy s7 (G930A) At&T Root problem

Hi, I rooted my galaxy s7 from att using this method, https://www.youtube.com/watch?v=GNInTlCpv8E
It worked perfectly and I had my new rooted phone! So a couple of days after the root one of my apps stop working and I cannot get it to start working, it was a pushup workout app, so I restart my phone and it gets into a boot loop stuck on the at&t logo. I was very sad as I did not back anything up so I wiped my phone using the recovery boot and signed in and re-flashed the root rom through odin and re-installed supersu and it worked perfectly again. The next day I have the same problem but this time with snapchat and instagram so I knew what was going to happen and I restarted and it did the same thing. This time when I went into recovery boot I noticed "dm-verity verification failed" in red at the bottom. As of now I am just going to do what I did last time and wipe and re-flash as I made a backup this time and just restore my phone and hope it doesn't happen again. If someone could please explain why this is happening and maybe help me fix it I would be so happy thank you!
UPDATE 7/26/16: I re flashed the ap root file with odin without doing a factory reset and it is still stuck in a boot loop, meaning I have to do a factory reset to get it out.
Mine is doing same thing. I used chain fires root. Everything went perfect. Then couple days later apps started saying they had stopped and phone started freezing. Every app I tired to open would say they had stopped. Then it constantly kept saying Google play services had stopped. I tried to reboot and stuck into bootloop everytime. Rooted again same thing happened again. U ever find a fix or anyone no how to fix this

Encryption unsuccessful random! Need help. Galaxy S3 CM 12.1

Sup guys, so i just had a really strange problem that popped out randomly, i was watching a youtube video and i had to help a person quickly and when i came back just a minute later i saw my phone showing encryption unsuccessfull when i pressed the power button to turn my screen on. Well it said to factory reset my phone, i don't store any important data on my phone anyways so i just went for it, and it restarted went to my TWRP recovery and tried factory reseting it, to no success. It basically failed to access /data/ and other directories and i can't see any files in them through recovery. And so i can't even factory reset it, i can't install a ROM cause the partition is corrupt i assume. How can i "unbrick" this? I was running the good old Temaseks CM 12.1 ROM, has been working fine for a looong time. My PC recognizes the phone but i can't access any data, it just shows that it's connected, odin doesn't recognize it.
Can somebody help me please ? I use my phone alot and it's really important.

Galaxy S9+ G965F Bootloop problem, need help

I woke up with a black screen and unresponsive I soft reset and booted back up just fine, fast forward 2 days, apps are constantly crashing and often seemingly randomly the phone will restart and go into a bootloop anywhere from 1-5 minutes before it finally boots. Sometimes I get lucky and can use my device just fine for a few hours, then apps will crash and stuck back in bootloop.
I have factory reset in recovery, and also flashed latest stock rom via odin, I am new to this and this was my first time I might add, it passed but it hasn't resolved the issue, is there anymore steps with odin or anything else I can do to repair this? The device isn't rooted if that helps.
I think that's a motherboard issue
You could try installing a custom rom
