Unfortunately, Android System has Stopped! Help Please!

Last night I decided to switch to ART from Dalvick runtime. Ever since, when android finishes loading, I get the error message "Unfortunately, Android System has Stopped." I've tried returning to stock (I'm rooted) and neither of my windows computers can see my phone which is weird because I unrooted my LG G3 recently with no problems. I've performed a hard (factory) reset numerous times. Sometimes the android system loads up OK but as soon as I reboot or power down I have the error message again. I'm at my wit's end. I can't return the phone because it's still rooted and I can't get it to work. When it boots, the LG screen appears normally. The At&t screen appears normally. Please help! I'm desperate.

If you're okay with losing info, give this a shot. I'm not sure exactly why it's doing this unless you had xposed framework before. Anyway, follow the steps and it should fix it. I'm not sure if you've tried going into the boot loader yet and doing a factory reset through there. So you can try whatever you like

I can't get a computer to recognize the phone. I have tried a hard reset and I still get the error message. Any other ideas?

I had the same issue after I tinkered with something I shouldn't have tinkered with. I think I installed GravityBox, didn't like what it did, tried to factory reset, and started getting the Android System error consistently.
That link mcnick posted will serve you well. I would however use this thread since it's tailor made for the AT&T variant.

Boot loop on optimizing apps

I have the US 32gb unlocked version. Tried to do the downgrade to install CM using the method mentioned several times that changes the version from a command put in twrp.
First I unlocked bootloader, then installed twrp, then did the command line thing to lower the fw version, then put the v1.12 firmware on zip then rebooted to install.
Well, the install failed so I decided to stop there and try to put everything back to stock by using the latest ruu exe from HTC. The exe started sending a file to phone, then locked up and threw an error. I restarted the exe and it finally passed. I got everything set up and went to bed while it was updating apps.
This morning, shut off phone to put in SD, and when turning on it was optimizing apps then when done, would reboot and optimize again. The phone was stuck in this loop until I let the battery die. I couldn't do anything with it.
Battery finally died and tried to run the ruu exe again. This time it would not pass at all, no matter how many tries. I wanted to try to run the zip from SD but the latest firmware I can only find as exe.
Finally decided to just do a factory reset from recovery mode. This let the phone boot normally and I could do set up again. I tried doing a soft reboot, and it booted fine. Then I disabled apps I don't use, and did a full power down, now the phone is back to doing the 'optimizing apps' bootloop.
Right now I'm waiting for it to run its battery down again so I can at least get to download mode/recovery. Maybe I will try a full power off and app disabling separately, to see which is causing the loop.
Anyone have an idea what's going on? A link to the latest ruu in zip form? I really need a sure fire way to get this thing full clean stock (remember the exe is failing for me) to eliminate if thats the cause. Is it because I edited the version number?
Edit: just realized I put this in the wrong section

Update: Once battery died, I did factory reset again from recovery. Went through setup, and I then immediately shut the phone completely off and turned back on. It booted up fine. I then went to disable the same apps as before, EXCEPT for the "Google App". Phone still powers up fine, so I left it there and phone is working fine. I didn't want to see if disabling the Google App was causing the phone to boot loop. I had that app disabled the entire time I've had the phone, but don't think I've ever completely shut the phone down, so maybe that's why I never had the problem.
Still don't know why the ruu exe didn't work. Hopefully it was the computer, and I can still take updates.

I have the same problem, can't disable apps without phone going into bootloop on restart. Can you tell me what apps did you disable? Facebook, Instagram, Google docs, HTC apps etc,etc...

I think what caused my problem was disabling the app called "Google App". No problem disabling all the Facebook and Instagram apps.

What about Google docs, slides and news apps? Can those be disabled?

Same problem with my A9 bought a week ago. Like Rouyal, I recall disabling the Google App and then came the OTA update and the bootloop. Tried alll permutations of buttons and even when I could get to RECOVERY MODE, all the options looped as well, returning to the same screen: no bootloader, no recovery. The only alternative screen was the "Enter your code to decrypt your drive" after leaving RECOVERY MODE. It looped as well. Copied the stock RUU to an external SD card; did nothing (with HTC Sync).
SOLUTION: Enter wrong codes for the "decrypt your drive" screen 30 times; that is the limit before the drive gets a factory reset. After the 30th it was factory reset. On restarting, the systems asks for the SAME email that was used previously.

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...

Galaxy S7 G930U Unlocked stuck in boot loop - already flashed successfully but no fix

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.

Debugging J7 Prime Restart issue

Pardon for a long story but someone gave this Samsung J7 Prime(SM-G610F) to me with an issue "An Error Has Occurred While Updating The Device Software". So I gave Samsung Smart Switch a try sadly they removed the Initialize option and old version don't seam to do what it suppose to do so I wen to a traditional Odin flashing. I then look for a stock rom for the phone that I think is the right one. Started with android 6 MM region pakistan and flashing went well. I was able to use it for a good hour or two until I notice it restarted by it self, then it keeps doing it 10-20 seconds after booting up. I though its the firmware I'm using so I went and look for Oreo version this time I region india (I don't know if region matters). So I flashed it again and tested the device again. I'm still able to use it for a good while till it restarted again. I then keep testing it to see what may be causing the problem. I notice that when the WIFI is on it just crash the phone to reboot so as soon as the phone reboots I turned the wifi off and it didn't crash anymore. I then factory reset the phone cleared everything, wipe cache then installed benchmark tools first. Thing I notice is it crashes when Google Play store is trying to install or download something. I tested it a couple of times to see when it crash and it does crash when downloading or installing something. I was still able to install 3Dmark and run it with wifi off. It completed the test without crashing so it couldn't the processor issue. I then look for another rom and tried flashing it. This time I had issue with it failing at system.img even if I use recent rom that worked. I then keep trying till flashing TWRP worked and flashing the rest of the rom is fine again.
What bothers me is why doesn't it crash during the first couple of hours. I've search similar issues and they say it may have been and app issue. I've already disabled bunch of app but nothing changed. Run the phone in safe mode but this time instead of crashing and rebooting right away it freezes for a few seconds. I suspect if google play or something being an issue since I've tried disabling it and it didn't crash for a couple of hours. Looked for allot of related thread but none of them seam to solve my problem.
I suspect either its the rom that I'm using and it can only be fixed by using the original rom, or its having a memory issue but don't know how to pin point it. Anyone can suggest on how I can debug this? I'm used to debugging things in real time and my knowledge with android is a quite slim but as a programming understanding the errors won't be a problem. I hope.
Edit: Hmm. Does copying kernel log with TWRP work or the kernel logs get overwritten every time the phone reboots? Because I see the kernet logs but don't see anything failing except for something saying SHUTDOWN but I don't think thats it. :S

Still no reply. :S I think its /system dismounting it self while doing a write operation. but it doesn't trigger until a certain amount of time after the phone is flashed or factory reset. I have to go to recovery and mount system back but that only happens on marshmallow. over version it remounts it self after the random reboot. After factory reset I'm able to install COD mobile and play a couple of match. after a long while it just decides to reboot.
I also tried z3x and after reading PIT from phone OK. the phone just reboots and flashing completes without it doing any flashing.
