Galaxy S6 - freezing and rebooting 50+ times a day

I've got a Vodafone UK version SM-G920F that has recently started to freeze, crash and reboot constantly.

I managed to back up my data and perform a factory reset from the Setting page, but it crashed 10+ times during the install process (would freeze at various different stages, either rebooting on its own, or requiring a Vol Down+Power reset)

I'm now on a fresh install, but it's still rebooting constantly. I managed to use it like normal for an hour today, but right now it's just rebooted 3 times and won't even get past the Samsung loading screen without several Vol Down+Power resets.

What other options do I have? And is anyone aware of a known hardware issue that could cause this?

I was considering flashing a different ROM, but I'm scared it would reboot during the process and corrupt something...

Maybe a battery issue?

a friend just gave me his very same model phone with the very same issues.. if I find out anything I'll tell you here, or if you solve it first please write down what you did.

Thanks Vibbuz.

I've been trying to download a stock firmware to flash via Odin, but download speeds from Updato are really bad.

• #5

So I managed to flash a firmware after installing Odin on a Windows laptop (painful trying to get it to work on my Mac)

Firmware installed OK, but after boot I was getting a constant "com.sec.epdg" pop-up box that wouldn't let me use the phone at all. Not sure if that's due to the tsar3000 firmware?

Wiped the cache and did a factory reset after booting into recovery, and now it's stuck in a boot-loop again (95% of the time it hangs at the Samsung logo animation)

Just tried using SamFirm v0.3.6 to find the correct file. Downloaded a 4gb file, but several attempts to extract only gives BL, CP, CSC files but no AP (throws up an Unknown Error during process).

So still stumped!

• #7

Yet another update. Left Updato running overnight and downloaded a firmware.

Flashed it with Odin, claims to have succeeded but phone then reboots and hangs at "Erasing" stage (Android logo is spinning, then stops)

I'm starting to think it's pretty broken...

• #8

I've been having this exact same issue since June. If your phone happens to boot try activating power saving mode (to reduce cpu speed) as soon as possible.

It seems that doing that diminished the frequency in which my phone rebooted. If it also helps you it might be a faulty battery that can't provide enough voltage. (I'm not 100% sure on this part though, just thought of it because of the apple batteries drama)

Please post your results! Looks like a lot of people are affected by this and it would be great if we could find the cause of the problem.

• #9

I just read your thread actually! Sounds very similar to mine.

I've got nowhere. I don't think it's hard-bricked as I can still access Odin mode on the phone, and sometimes boots to Recovery, but it freezes and various different points and is currently unusable (either freezes at Samsung logo, "Erasing" part after installing firmware, or once it started to run though new device setup then froze).

Went ahead and bought an S8, but still want to fix the S6!

Does it have twrp? Try a non stock ROM and kernel

Hi I have same Problem I send the my s6 for repairmen that Saied me this problem related to mobile Hard drive.
I didn't believe it and try some official rom and a rom from Philippine GLB solve my problem for 3 M/o but now developed as same problem whitout any successful rom installation.
I think this problem from incompatibility google play store version to my rom. please flash a custom rom without google apps and immediately after installation turned off data and Wi-Fi internet after 2 day whit sim card whit out any change in setting can use it.

Hello,
anyone found some kind of solution? Happened to me also - freezing, restarts and then my S6 stopped working.. Sometimes I can boot to recovery menu, sometimes it boots up to android (and then freezes again), but the chances are almost non existing. Service man told me the same thing as @ghasemzm - eMMC failure. Yes, it is completely possible, but i don't wanna believe it, because they only tried to reflash the rom. I've made some "google research" and found that there were some issues in power IC on S6/S6E. Could this be related to it?

Will test the theory and let the group know.

So i have installed philipines latest update 6.0.1 i think with PIT file provided on Sammobile.

I have tested it for a day with normal ussage like i set up every other phone and it still continued restarting.

Figured out let me test with no google account signed in and the phone is working perfectly. For a full day.

So i dont know what the problem is but i will try again with google account tomorrow for a day see what happens.

After that will install 7.0.1 uk update with PIT file for it and test with that.

• #16

I have the same problem and I am quite sure that it is the mobile hard drive.

I tried to use F2FS but didn't find a working rom for that.

Samsung refused repair because of root.... Never Samsung again!

• #17

same issues here - any solutions found? My best guess is hardware fault...
