Galaxy S9+ G965F Bootloop problem, need help - Samsung Galaxy S9+ Questions & Answers

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

Nokia reboot problem when trying to update

Hello!
I have a strange problem with my phone it wont update to latset firmware without get in some kind of boot loop.
The phone was runing the lastest firmware 1232.5962.1314.0017 before the problems started, it all started when some systems apps like camera, settnings, messeging. etc, stop working. All that showed up when entering the apps was a black screen say something like "reconnecting" and then it jumped back to home screen.
So I restarted the phone but then went in som kind of reboot loop where it wouldent go past the nokia logo. I tried everything soft reset, hard reset. The last thing I tried was to reflash the phone, I tried diffrent ROMs and it finaly worked with the ROM 059Q5C6 RM-821 GLOBAL BLACK SWAP.
The phone is runing now and almost all functions work exept camera and automatic brightness (all that I discoverd so far).
Its currently running the 1231.5951.1249.1004 firmware.
But like I said now when I try the update the phone it goes to the same boot loop state.
What should i try next?
Is the thread in the right place?

Same thing happens to my phone!! Did not think that it could be the latest firmware (1308 for me) could have caused it since I don't think there are a lot of us affected by it and my phone has been running fine for months after the update! I've restored 5 times, by the time I thought to flash it, it wouldn't charge anymore.... I'd sent mine for repair now... Have you fixed yours?

[Q] Continuos hangs issue

Hello,
since yesterday my Galaxy S2 (summer 2011) started to act wierdly and I am trying to figure out what is the problem.
I was running the latest Sentinel ROM, and I found it "freezed". So I forced restart long pressing the power button. After the restart, I found it freezed again after some (short) time. It also freeze on the boot process.
Apparently in a random way.
So I tried from recovery a factory reset, full wipe, and reinstalling the ROM. Problem still present.
Today I tried logging with ADB logcat, but I can't figure out the issue from the log. I thought a problem with Mali driver shipped with the ROM, but actually it freezes sometime also on boot (so before loading the drivers)
I tried then to flash back the Samsumg original ROM (JB 4.1.2), which apllied nicely. However it freezes also with Sammie's ROM. Also on boot. By example I one time I got the black screen with the writing "Samsung Galaxy GT-9100" getting grey, with some horizonatl black lines. So frozen.
Flashed again with ODIN, again nicely, but it keeps on freezing on boot.
I am clueless. Could it be some issue with the battery? (it's the original, never replaced)
Any help or suggestion appreciated
Thanks
Update:
I tried to flash it back to GingerBread stock by Samsung with Odin. Applied nicely.
It still keeps on randomly hanging :-|

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

What could be wrong with this phone?(Freezing, restarting, doesn't detect carrier)

Ok hello i'm pretty new to this, but I have looked around quite a bit and nothing seems to help. So my friend gave me this Galaxy S6 edge(more specifically the SM-G925I - TCE Mexico (Telcel)). The issue with this phone is that it freezes then restarts randomly and it also doesn't recognize the carrier. It recognizes that theres a sim but the carrier is not recognized and I don't have access to mobile data. The bigger issue at the moment is the crashes though. I already tried resetting to factory defaults, booting in safe mode, wiping the cache and wiping all the data/ factory reset from the recovery menu. I thought it was the OS or something so I installed twrp wiped EVERYTHING(pretty sure I did since when I rebooted twrp told me if I was sure since I had no os installed) and installed the official 7.0 firmware update from sammobile. It was previously 6.0.1 and I thought having a different version might fix the issue. Yet the issue remains, within a few minutes of me using it it freezes, turns off, and reboots. At this stage I might you might think its a hardware issue but when i'm in recovery or download mode it doesn't turn off. Also I decided to leave it charging when I left for work and when I came back it hadn't turned off at all. I checked the uptime and it was at 7 hours and yet within a few minutes of me checking the settings it froze and turned off. I'm not really sure what to do anymore i'll probably take it to a service center to see whats up but I wanted your opinions first. Thanks.

Boot loop

Hello. I have a boot loop issue with my SM-G850F. It happens immediately after camera launching, boot loop can last for minutes, but eventually the phone turns on and works alright except camera. Sometimes camera may work fine for some time but later it goes to boot loop again. Also if i restart my phone manually it also goes to boot loop. I tried to reflash it using Odin, different firmwares, home and factory, Kitkat and Lollipop, i did it with data and cache wiping from recovery every time. When Odin finishes it's job and a phone tries to reboot after reflashing - here boot loop starts again. But when i reflashed 4.4.4 and got a Lollipop OTA update, my phone got back to life, camera worked fine, it restarted fine with no boot loop anymore. But after about 6 months it happened again. The same situation, wiping didn't help, reflashing didn't help, and again reflashing 4.4.4 + OTA update did help, i don't know for how long. What may be the reason? I assume it's not a camera problem, OTA update shouldn't fix it, and it's not a battery for the same reason. What do you think?

Maybe a hardware issue? Did you try ozcan or epsil rom? Do you have the same issues on those roms?

After several hard resets the problem has gone, i don't know for how long though. So i have no idea is it a hardware issue or not. May it be a flash memory problem?
