Hi, I installed an update to my S7 Edge (Australia) - I think it was Feb security updates.
My phone would occasionally reboot by itself once in a while before this.
After this update, my phone crashed while making phone calls, and then it would mostly reboot itself after 3 minutes every time.
I didn't want to play around with Custom ROMs just yet, so I installed Odin and flashed the stock XSA firmware for my device.
This was successful, but now my phone still keeps rebooting while going through setup, join the wifi network, and... reboot. Or up to add your google account, Just a sec, and ..... reboot. Or gets up to "which apps do you want to sync" and then reboot.
It's also been freezing on me in recovery mode.
Is this a physical fault? Any ideas? thanks
Tried another factory wipe after flashing stock firmware?

Good day everyone
I'm having strange issues with my sister's S4.
Not long ago, I saw that there was an OTA update available for 5.0.1, and I started to download the update.
It installed without a hitch, and it works very nicely and is noticeably smoother and more responsive than when her phone was still on 4.4.2.
However, for some strange reason, sometimes the phone will not wake up after pressing the power button, or letting the screen timeout.
Nothing will wake up the device, and not long after becoming non-compliant it will reboot itself. More often than not, it won't even reboot and you have to remove and reinsert the battery.
This behavior is completely random. It can happen 3 times within an hour, then be fine for the next 5 hours before it does it again.
I have done almost everything within the realms of keeping knox set to 0x0 (phone isn't even a year old yet, and it never had a custom ROM/kernel/recovery or even root!)
The first thing I did was wipe data/factory reset within the built-in recovery, as a first step to see if that might help, but the problem still arose.
The problem came back without even touching the phone at all (no apps, accounts or anything was installed after the factory reset was done, and the problem showed up within a hour)
I decided to flash the phone via odin to see if that will fix it, and thankfully I had the firmware for the phone ready and waiting long before the initial OTA update (I've planned the initial flash to 5.0.1 long ago)
So, I flashed it via Odin to the lollipop firmware I downloaded months before (United Kingdom (Black Edition) from 2015-03-16) and it succeeded without problems.
BUT, the problem is still there, even after resetting it, flashing via Odin then resetting it again!
I really don't want to trip knox, so my options are limited.
I haven't tried using Kies, but I doubt it will fix it, if even Odin can't fix it.
Any ideas on what I can do?
Hey all,
I found few similar threads, but none of the solutions worked for me. So here's my situation
Problem : N910G Singapore Starhub, used for more than 1 and half years without major issues. Suddenly started to randomly freeze and then restart.
Got worse very quickly. Started to get freezed at Samsung logo. Most of the time had to remove the battery to re-try booting.
What I've done so far:
Cache cleared -> Didn't work
Factory reset -> Was ok with less lag (Freezing) for sometime, then same again
Installed TWRP. Flashed PIT file. Following an XDA post, flashed Samsung stock Android 6 released to India -> Was ok for couple days, was better than 5.1 in terms of responsiveness and battery life. After few days, again freeze. restart
Flashed with stock 5.1 released for the correct region. -> freezing, restarts. Wifi passwords are not getting saved (Have to re-enter upon restart). Restarts end up in download mode. very rarely passes the Samsung logo
Rooted and tried to change build prop ro.securestorage.support (or something similar) and see whether passwords are getting saved -> Still passwords are not getting saved. /efs is accessible.
Now the device never boots properly. Some apps are missing after restarts. Always ends up in download mode. Recovery is working fine though.
You guys have any idea what else I should try before throwing this away?
Thanks in advance.

If you know how, I'd use Odin to restore the factory image if you're running the factory software. Performing a hard reset is always the best way to go, however if you're still having problems then I'd download the latest firmware from Samsung's firmware site and then Odin.

Thanks for the reply Android Ninja. As the last resort, I did flash the correct stock firmware which I downloaded from Sammobile. But it didn't really fix the issue. So should I unroot and use Kies instead? Because I can't find a way to download the fireware from Samsung, if that's what u meant. thanks
For a week my G935A worked fine... direct out of the box I flashed ENG Kernel and Rooted, then installed apps and configured - no issues.
Today it was working then it hung on wake.. I tried to reboot and now it gets stuck at the AT&T logo and vibrates 3 times - over and over
I can get to Odin and Recovery screens easily so I tried to flash the ENG Kernel again & deleting Cache Partition few times - didnt fix it.
Also tried booting into Safe Mode - it never gets there, stays at AT&T logo.
When I go into the Recovery menu, I see at the bottom, in red... "dm-verity verification failed"
Anyone know how I can recover from this without Factory Reset? It took 6 hours to reinstall and config all my apps - really want to avoid that.
thx for the help!
as far as I know there is no way to fix and save your stuff. I had the same problem with G930A and even doing a factory reset would only allow my phone to boot but then I get apps crashing and then a reboot puts you back at ATT logo and the vibrates. Best to ditch the whole engboot and go back to stock until a more stable rooting method comes out.
Some searches shows posts that say using Odin to flash HOME_CSC without having to wipe and everything survive
... Where can I get HOME_CSC? I dl'd stock rom and dont see it in there.
thx!
Same here this morning on my 930A w/ PK1....went to watch a youtube vid and everything google related began crashing.
Only been on engboot for a couple days but did flash the v15 debloat last night. hmmmm.
Any luck with the files or procedure LivinOne?
Update: Flashed the PK1 CSC and got into recovery.
Wiped cache and reboot, same failure mode....sad face.
Flashed CSC again, into recovery, factory reset, wiped cache.
Back to setting my "new" device up.
Dec 30 update: Same crash, SEMI same problem.
I get the single vibration followed by the 3 vibrations after I put my pin in from a restart.
Same symptoms prior, all background activities began crashing.
Running all PK1 files from QRhinehardt post.
Any thoughts?
I ended up wiping and flashing the T-Mobile firmware and using the ENG bootloader (but not rooted yet). It is WAY faster than the AT&T was. I've only had issues with Wifi Calling (it doesnt seem to work most of the time)
s7 at&t
Hi, did you first flash with eng bootloader and then tmobile rom? I miss this step...I appreciate your help please
Single vibration followed by the 3 vibrations
Hi, were you able to fix the problem? I'm also getting the single vibration followed by the 3 vibrations.
Do you know why is this occurring? I performed a wipe cache and factory reset but still nothing.

I had rooted my S7 edge (Exynos) a few months ago. I tried installing the ambasadii.zip rom.
I also followed there instructions to the letter.
Upon restarting the phone it started loading the apps, but then stopped halfway and froze. Sometimes restarting to then freeze again.
I reinstalled Recovery ROM and after many tries was able to install via Smartswitch the Stock ROM (Sammobile) 7.0 DQB3
Since then I have had a couple of crashes (average 1 a week). Once when opening Alto (game). The screen froze with a horizontal bar with stripes in it. Booted into recovery and factory reset but had to install stock again via Smartswitch.
Yesterday again a screen and system freeze. Thankfully I was able to restart.
I tried wiping everything with TWRP once I was in TWRP. But it seems that there is something else wrong. I would not mind going right back to full stock (I know the knox counter is tripped). Am I doing something wrong in trying to install the stock fw thru Odin3.12.3? Do I need a specific Revovery file? I am wiping with TWRP but someone else suggested that I had to format with TWRP, could this be the issue?
Or are others also having random crashes?
So i was simply updating youtube through google play, and messenger through messenger it self and suddenly the phone went into boot loop and can't get it out.
opening recovery mode is hard but when i managed to do it, it simply shows the android icon and installing system updates then restarts again. (tried it ~4 times). thanks to that i can't try clearing cache or any of that stuff on the list that is supposed to appear in recover mode.
trying force restart also does nothing.
trying to remove memory card and sim also didn't work.
i read that flashing HOME_CSC from a rom could fix it but the rom websites i know offer limited sizes and speeds and i don't have a strong internet which ends up timing out, can someone help me out? G935FOJV2ERGE is the one i need.
if you have any other ideas that can help, i would also greatly appreciate it, i really don't want to have to buy a new phone atm, and don't want to lose all my data because i don't used backup services cuz they ate up data .
edit: I am on latest official rom, only used OTA updates, haven't rooted the phone.
edit 2: i managed to get a different region's rom and flashed it's home_csc file, and force restarted it and seems to have worked booted, then it started doing it again just 1 second after that. i didn't even have time to unlock it.
edit 3: managed to get into recovery mode list once, wiping cache didn't work. couldn't get into recovery mode again after that. then i gave up and tried flashing a full rom. still the same problem.
