[Q] Restart loop(not bootloop) - really weird

Hey lads,
I got a really weird problem and I've tried nearly everything I can think of. I had EMUI 2.3(b121sp06) and I tried the online OTA update to b307 if I remember right(was automatically suggesting the update) and at the update screen it loaded to about 99% and then stopped. Said not to press power while on this screen but obviously it wasn't going to finish. So I reset the phone and it started the "recovery loop", so basically keep trying to apply the update. I had to flash CWM to break out and flashed the whole system by hand(recovery,system,boot,cache,cust and userdata img files) and it starts up but it keeps resetting and seemingly it's random. Android boots up, I don't touch the phone--> boom reset. Weird thing is it even does it in recovery.
If I really want to explain the problem it's like as if my finger got stuck on the power button(that naturally made me think that the button might be f*cked), but booting into fastboot and not having resets cleared my suspicion. What I also noticed is that every time it boots up it doesn't recognize the sim card and I have no signal or whatsoever.
Tried multi tool unbricking method -> doesn't work
Tried factory reset from stock recovery(had to be fast so it doesn't reset before) ->doesn't work
Tried wiping dalvik cache and factory reset from CWM ->doesn't work
Tried killing battery by letting it keep resetting -> battery drained, reset loop stopped ->put the phone on charger->reset loop started again
I have no f*cking clue how can I get out of this, will keep trying though. Any help is appreciated, thank you!

Hi
Did you try to remove the Sd Card ? Honor 6 reboot is often due to faulty SD Card.
Which model do you have ? L04 ?
B307 upgrade sure ?
Seb

Yes, that was my first idea, still does it though. I have the L02 and I'm not positive it was b307, but it started with 3, could be b303 if there is one.

I don't know for L02 but for L04 there is a Full ROM that you can flash with the three buttons method. (Vol+,Vol-, power and put the ROM in /dload folder on the SD card).
Maybe there is such thing for L02 ?

There is, but as I said the phone restarts even in recovery. It's like the phone restarts every 30 secs except for fastboot.

if it's not SD card or internal flash problem so, it seems to be hardware related to me (

Would make sense but it occurred only after I tried OTA. Would be really surprised if that killed that hardware :-/

Unfortunately not, I'm out of ideas, trying to negotiate with the seller to sort something out, I think the phone is beyond saving

Same thing happened with me. Don't have any solution. Have you fixed it?

Its might be a battery problem Or power flex cable. Try to turn on the phone during charge

guys im facing the same problem now... waiting for any solutions

I have tried stop & uninstall some app
I've tried as quickly as I can when the phone (nokia x) is on, then I stop> uninstall I consider potentially cause this problem (facebook, whatsapp, uc browser) and then it managed to prevent the continuous restarts. but problems arise even though the application had me uninstall and then I restart the phone. and it is back again, I uninstalled the app that has remained with the error settings and restart repeatedly. who knows what else : '(

Did you follow the guide here?
Sent from my Honor 8 using XDA Labs

In the past my battery lost it's endurance pretty much. Furthermore I've read that a defective battery causes lots of weird behaviours on our Honor 6, which was the same to mine.
In my case a replacement of the battery worked well, to get my Honor 6 back to life:

It's not that difficult and lasts approx. 30-45 mins. Spare Batteries are available for 6 - 10 bucks on ebay or directly from the chinese internet stores.

It's really important that we use original chargers for the health of our device.

S7 Keeps (randomly) rebooting

Hi Guys,
My S7 (SM-G930F, Netherlands PHN device) randomly reboots. I cannot use my phone anymore because it reboots somewhere between 5 seconds to max. 2 minutes after it reboots.
What did I do to try to fix it:
1. clear cache + full wipe via the recovery mode.
2. downgrade to stock (PHN via Sammobile and ODIN install) Android 6 rom (and after that upgraded to Nougat 7).
3. Fully charge battery and let it drain down all the way.
- My device is not rooted but original Samsung
- My device does not have a single scratch nor it ever fell down
It looks like a hardware problem to me or am I missing something?

I had the same problem with the Galaxy A5 2017. Couldn't fix it, decided to return it, and even the carrier couldn't fix it so they gave me a new one which didn't have the problem. So, if you're still under warranty, return it.

Hi @sanderh
I had the same problem with my G930F for a week. I left it off for 5 days. After that time I turned it on and it's fine now. Two months without reboots :victory:

No reboots to this day :fingers-crossed:

After one year the restarts returned. This happened while updating to Oreo. I left the phone switched off again for 5 days but the problem remained.
When I made a backup files from phone to PC, I noticed that everything works when the MicroSD card is removed. No reboots. I decided to change SD card - it worked. Formatting the memory card also helped so... I'm enjoying again with the working phone

Samsung Galaxy S6 randomly restarting / gets stucked

Hello guys!
I am encountering an issue with my Samsung Galaxy S6 G920I. The phone suddenly started to restart on its own every 30 seconds or so. After some restarts the phone started to get completely stuck in a randomly time matter, and the only way to take it out of there is by doing a hard reset (volume down + power buttons).
I tried everything. Did wipe cache and factory reset in recovery mode, flashed a new stock ROM with Odin several times but it is still doing that.
The stuck issue also happens on screens like "installing update" or "erasing", after doing the ROM flash with Odin.
Any thoughts?

Try device initialization using SamsungSmart Switch. it Should solve the problem. But that method wipes entire internal storage. So backup before you do anything,
Device initialization is something like resetting it to factory setting by clean install of the firmware.

Hi, could you fix it ? The exact same thing happened to me. I was using stock firmware (I never rooted it or anything) and it suddenly began to reboot by itself. It can be stuck in a bootloop for 2 straight days and then suddenly boot normally and use it for a couple hours until it starts bootlooping again. After a month of having this issues I decided to flash stock 7.0 firmware with ODIN and also with Smart Switch but after succesfully applying the update the phone reboots with the "installing system update" screen and then it gets to 32% and it says "erasing" after which it starts the bootloop once again. I'm stuck with a $500 paperweight. I'm afraid it could be something with the motherboard any help is greatly appreciated!

My G930F Reboots every few seconds even in recovery or charging when powered off

I recently bought Galaxy S7 with nougat updated. after few days I received an OTA and updated it. After updating I got my phone restarting every few seconds. I tried to wipe cache but it wouldn't help. Then I tried to factory reset using recovery but it restarts every time during the reset process. If I try to charge it powered off then again it does the same and startup automatically after few seconds. I tried to downgrade and tried 3 previous nougat roms from updato. Also I tried to downgrade to Marshmallow but nothing helps. Even I tried nand erase all option but all in vain.
Any help would be appreciated. Thanks

RMA. it looks like motherboard failure.

Latest fw is causing such problems, search the s7 edge thread and google

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.

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!

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...

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.

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

So did anyone manage to find an issue in this rebooting. I am having the same issue.

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.

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!

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