Hi everyone,
Someone asked me to fix his phone and i'm stuck. The S7 is crashing randomly (black screen) and after a crash, it cannot be booted until the battery is dead (even by pressing power +home or power + vol-) and charged again. I don't know how to fix it and i'm stuck at this point.
Here is the story behind it :
The phone wrote the famous "moisture" message and then won't boot up. He never put it in water. So he put it in rice but it didn't work. The owner of the phone took it to a fixing store in Thailand where they changed the battery. After a day, the phone crashed and we send it to Samsung Thailand who told us a high cost without explanations so they didn't fix it and we got it back.
Hopping someone can help me about this problem :angel:
Update :
A deep-clean flash () got me stuck into "no command" and pushing vol+/vol-/home didn't change anything, it just bootlooped.
So then i tried installing TWRP 3.1.1, it's a success but after installing LineageOS 14.1 and booting the phone crashed at bootlogo and won't boot up again...
Another Update :
I finally managed to get it working saturday, but it crashed just today and it's the same. It crashed in a lightweight app with no app running in the background. I'm thinking of a material problem :/
New update, still hoping someone know how to fix this:
I tried to flash stock firmware over and over but it keeps crashing at the end of the boot animation... I'll try an oreo firmware, hope it'll fix it

Hi guys, so recently I bought a Galaxy S6 Verizon off of eBay. I got it for fairly cheap because it was stuck in a boot loop. I usually have no problem fixing stuff like this, but this time is different. So the first thing I tried when I got the phone was to do a reset and cache wipe from recovery. I rebooted the phone and it showed a screen that said "Android is starting, optimizing app 9 out of 31." when it got to 21 the phone rebooted and went back to 9. It did this several times before I attempted to wipe/reset again. I then downloaded the tar file G920VVRU4CPH1 and flashed it in Odin. I did a manual reset before the phone booted, and it is doing the same thing again. reboots to a green screen where it tries to optimize apps, stays there for about 20 seconds, and reboots over and over again in the same cycle. I have tried all other stock marshmallow roms that i can find, Odin won't flash older ones, (assuming its not letting me downgrade). Also another weird thing, every time I flash, the blue update screen goes to 32%, stops, erases, and reboots. Phone is on 6.0.1 version MMB29K.G920VVRU4CPH1 as seen in recovery. Any help would be gladly appreciated. Thank you!
I am having a similar problem with loading new rom. The farthest it gets is 32%. Sometimes it doesn't get even that far.
I ended up just buying a trashed s6 and swapping the motherboards. Only way I could fix it
I've had my S7 since March. Worked flawlessly until around 2 weeks back. The first issue I got was that the phone stopped responding. I haven't linked that to any specific application. It happened at random. So the phone freezes and screen goes black. I used the Power button + Lower Volume button to power up the phone again and it worked. But then the no response problem happened more often. So I decided to go for a factory reset. I did this using recovery. But I continued to get the freezing issue. And the last time I got it was a few hours ago. But this time when I used the power button+ down volume button, the phone got stuck in a boot loop. I managed to bring up recovery to power down the phone. When I booted into recovery, I got the a dead android logo with a yellow exclamation mark in a triangle. I tried to power up my phone back, but it again got stuck in a boot loop. I know I can resolve this situation by doing a reset again. But I suppose this is not the solution as I will continue to get the freezing and not responding problem again.
Any advice please?
Thank you.

Hi mate
after you factory reset it , did you use the phone for a while without restoring any app?..so you are sure is not an app making the mess
My first option would be flash ( odin) firmware again.....
Check his guide
Use home_csc instead of CSC so you do not lose anything
I actually didn't restore any app after reset. I rather re-installed only 2 apps I use most. And I've been using these apps since I started using my mobile. I don't think they could be responsible for the crashes.
If I have to flash, I've been wondering if I could have a go at Nougat.
Would that be a good idea?

Hi
Yes you can flash nougat, seems to be stable......but still is a Beta version
Hi
I got the same problem ... did you find any solution for this problem ??
Replacing motherboard fixes this issue. Its not software related. Faulty board. With Nougat this will happen even more. I know because happened to me..
ohhh
how much did cost you for that ?
I read in the thread guide that i should do this. just ignore it if i'm wrong.
Device: Samsung galaxy s6 edge SMG925f
Rom name: idk i can't even go to the home screen
Rom veersion: idk i can't evn go to the home screen
Build number: idk but i flashed an md5 file with the name G925FXXS5DQJ1_G925FOLB4DQJ1_G925FXXU5DPL6_HOME.tar
Rooted:????
no mods, i remember flashing twrp though
Okay to the problem,(sorry for my bad english) so my mom gave me a broken galaxy s6 edge if i fixed it then it's mine! but the problem is i can't ,it's been seven days since the first day i'm fixing this device.
at first it was stuck in a bootloop and 98% chance it will freeze during booting when it freezez it sometimes create lines of corrupted pixels i just press vol down + power to reboot.
I researched how to fix it and did a factory reset and wipe cache but still not working.
So i figured out i need to download a firmware to fix, so i downloaded one and it took two days because of the slow free download and frequent fails. i tried to flash it and i realised i downloaded the wrong one, so i downloaded one again and it took me a day. after that i tried to flash it using odin 3.12 and it fails during flashing 99% percent of the time because of the constant freezez and i need to press vol down + power for 1 minute for it to reboot now if i'm very lucky the flash will complete BUT during installation it froze at 24% so i flashed it again for the second time, that took 8 hours. and suddenly it to complete the flashing and installation BUT, upon completion it sudddenly says something like "No drk please install drk" i was completely infuriated and upon hours of research i found a tutorial where i need to flash auto chainfire so i did it, and it doesn't work it just cause bootloops
so after that i researcheed again and found this file kernel_G925f sforum i flashed it. and upon reboot it says 'Kernel is not seandroid enforcing' ,and it's not yet fixed it just cause bootloops and sometimes freeze on unfinished samsung logo animation.
I am now trying to flash firmware again to see if it could get fixed. every hour i am losing hope.
If theres any tips i could get that would be good.
If i fixed this s6 it'll be the biggest achievement of my life and own my first working smartphone.

Ahhhhh. forget it i finnaly fixed it the only problem is overheating. funny thing is i got rid of the freezing issue by hitting the phone against my leg.
Hey Samsung users.
my case is a bit weird.
i bought my s8 running nougat used it for 2 days and it was all good , so i received the Oreo update and updated it using the over the air when I received connected to wifi.
my phone started to reboot randomly even for 30 times per day , i tried several things like wiping cashe and the only solution that reduced the problem was uninstalling my installed apps. basically normal apps like facebook , whatsapp , spotify ,and even stock apps like calculator and music player.
today as usual I woke up picked up my phone and it started rebooting so i uninstalled some apps but it kept rebooting.
sometimes it reboots and get stuck at GALAXAY s8 boot screen [ not samsung flickering screen ] and all i had to do to overcome the boot loop is pressing and holding volume down and power button.
but one time it got stuck and boot looped once and for all. I tried to press volume down and power button to make it reboot again and overcome the bootloop but it rebooted and got stuck at the bootloop.
I tried to access recovery but i couldn't access it.
I can access download mode only.
my phone switches on itself when it is plugged in to charge , i can't turn it off completely to charge it while off.
I reflashed stock firmware and it succeeded using odin but the bootloop is still there.
please help me with my problem.
any slight help or idea would be a life saver for me.
sincerely,
Zack.
Hello
I am very frequent with root and roms etc. but i am facing a big problerm with my s7.
i had already rooted it long back and had twrp, worked great for a year.
but suddenly around a month back it started restarting on its own. and at times it would get stuck at the Samsung logo.
i didnt care that much but then it kept on increasing and happened very frequently. the system will boot up and within 5 seconds it will get frozen, and no its not an app coz it happened in Safe Mode also,
also the screen would become hazy, like the tv does when there is no chane, become greyish.
also when i boot in twrp it would get frozen, like during wiping cache or installing, it will just get frozen in between
i tried upgrading to oreo somehow it started but when i restarted it wont start up. it would be stuck at s7 logo.
TWRP still getting frozen also i have tried other versions, no luck,
then i installed resurection rom for s7, it booted up, was working fine but then when i restarted it would not boot up system.
thats the problem i am facing now,
i tried down upgrading to Nougat but now it will say updating system and then erasing, and then it would get stuck wont boot up the system. it will keep restarting and then get frozen.
Literally spent more than 24 hours on this and no luck
please help
