Hi everyone.
I have an LG G Flex 2 (H955) that suddenly went on a fritz. It used to be rooted fine, it was on default firmware, 10 something (wouldn't OTA due to rooting), no issues, but as I am a heavy user, enabled multiuser, had a bunch of apps installed and running it started to slow down on occasion, but nothing unexpected. Anyway, few days back, it shut down on its own while I was typing a message and the phone entered bootloop - on it's own. I decided to cut my losses and did the factory reset the hardware way, it booted up, did the "optimizing apps thing", got to welcome screen and - froze - then just restarted. It's been doing that ever since. Sometimes it boots all the way and then freezes and starts, sometimes it gets stuck on LG logo, sometimes even boots and works for a minute or two but still freezes and reboots.
I can access Download mode, and HW factory reset. I flashed several stock ROMs I found with LG flash tool 2014. It goes without a hitch, boots up, again gets to the welcome screen and reboots. I tried to to the dd cmd way to flash the only system.img I found online, but I get a security error at boot. It gets fixed when I flash the stock ROM again with flash tool. I am at my wits end. I have no warranty, I have no backed up original dump. With my limited knowledge I have somewhat of a hunch that one of the partitions might be corrupted as it boots most of the time but as it tries to write or read something from somewhere (hence showing the Welcome screen) it dies.
Would anyone have a suggestion as to what I might try next, or had a similar experience?
Thank you all very much in advance for any help.
Have you tried this tool with the appropriate image?

Hi and thanks for the tip. However, no, I have not tried this method as my device is H955, International version, and I am not keen on messing up the phone worse then it already is.
I will look it up in more detail, but as far as I can see it only pertains to the H950 (ATT version)
Edit: I looked it up in detail, and the developer removed the H955 support as there is a KDZ for it and he claims the .kdz is a much better option - however - .kdz does not work for me. It flashes the rom all right, both in Normal and CSE Flash modes, but the problem persists. Turns on (if I'm lucky), freezes, reboots and so on.
D'oh, didn't see the H955 part. :-|
Sorry to hear you are still stuck, can't offer much more unfortunately.
I know one of the flashing modes does a reset, but maybe a reset after the flash might help.. i think it's, from powred off, down plus power until the lg logo then release and then hold power on its own until you get to a recovery screen where you can reset.
you probably already tried that I'm guessing though. taken memory card out if you're using one?

Hi and thanks for yet another tip. However, you guessed right - I tried everything - reset from the recovery, before the flash, after the flash, in the middle of flash, with memory card, without memory card, tons of times - you name it, I've tried it. And still, it boots up (sometimes, though), freezes and go bye-bye. I'm completely out of ideas. If I could somehow rebuild partitions from Download mode, or use ADB, or push some image I found and flash it directly, but there is no way to push files to phone in Download mode (and 5.1.1. disabled external memory, so that is out of the option too).
It seems I'm stuck for now. I'm wondering if the repair guys have some tricks up their sleeves, perhaps with those hardware boxes, jtag something or other...
im on same boat with h955p, any solution?
the battery is the problem 100%. i had the same problem and i managed to fix it with buying a new battery and replacing it. 10$ on aliexpress plus you get the tools and it is really easy to replace.
hi. i was stuck in this situation. you can reflash the original stock rom back from LG UP software. at me this was the problem. my friend have a korean model and at him the 4g data connection was the problem...i was on the update of the marshmellow and freeze and reboot...factory reset didn't do something cool and keeps rebooting...but i was smart and lucky and my brain was thinking at the reflash of the phone...so i was to the reflash so my phone was completely and fully functional...no freeze , no reboot...and look for the v20a italy firmware (stock rom)...i say this because this v20a italy rom is so f***in stable and no battery drain...better than other stock rom marshmellow. Thanks me later.

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 :-/

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 : '(

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.

Guys i want to know whether lg g4 bootloop issue is truely a motherboard problem and if the motherboard is changed to a new one, does the problem also vanishes for forever.
Today I got my bootloop fixed!
After some weeks using Android 6.0 Marshmallow I got my battery empty over night. Next day I tried to power the device on again, no success. It was looping the boot process. First I though it was because of too low battery level, so I went into download mode and charged to 100%. After rebooting with full battery it was still in bootloop, so it was not because low battery...
I tried two days to get on my feet back again using LG Bridge ("Fix update Errors"), trying to get my internal memory copied ("Send_Command.exe") which gave "FAIL" only and to fix that beast trying factory reset, but it was not possible to get into recovery mode. So no success at all. I read about hardware issues and was close to give up.
Then I've found LGUP. First I tried "UPGRADE" using that KDZ-file from the previous attempts with LG Bridge. Two times, no success. Still bootloop. I decided to give up any chances for recovering any data and to go for "REFURBISH" ... YAY, It worked! Bye-bye bootloop! Now I have a fresh working device.
So, if you think it is not a hardware issue (mainboard) you might want to try this. Especially if you've used old apps (from previous Android 5.x times) or if you have deactivated too many pre-installed apps (maybe the LG ones). I think something of that was causing my bootloop and the first reboot because of the empty battery was finally showing the bill for that.

Sorry if its been asked, i tried a search but couldnt match my problem.
I bought a used samsung s6 for my son, it seemed fine when we checked it.
But its got an odd bug where if it restarts it gets stuck on boot up.
I've used smart switch to reinstall the offical samsung stock rom
The re-install all his apps.
The phone works fine and re-boots fine.
But after a few days, if restarted it wont boot and just gets stuck on the boot loadung screen. None of the special boot options helps, clearing cache or reset.
The only fix is to use smart switch to do a complete wipe and reinstall official software.It has never had Knox tripped, and the guy didnt seem to be the type to run a custom rom.
It getting to be a pain as he cant turn his phone off and if his battery runs down gis ogone will become useless until i re-set it and wipe all his data and settings. Which I have to do on an almost weekly basis
I have a few questions...
Is it a hardware issue? (It the stock rom on a phone thats never been modded afaik)
anybody know whats causing this to bomb in stock firmware?
Any idea how to fix it?
Would a custom rom fix it?

I had this problem with my brand new S6 when I first got it. Yes, random reboots were occurring every now and then, which I could live with. Then one day it just got stuck at the boot logo and didn't boot no matter how many times I re-flashed stock firmware with Odin. Turns out it was an issue with the Main Board inside the phone. Once I got it repaired it's been fine ever since.

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...

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!

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...
I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
