Hi, I have an S7 edge that started to reboot and hang everyday a while ago (2 month and have it for 4 month). Lately after reboot it got to a boot-loop point where neither clear cache nor clear data solved it and had to reinstall firmware. Did that for a while a couple of times which was frustrating and don't really know what the problem is, probably the motherboard as I read online. not sure at all.
Nevertheless, that is not my only problem since the last time I flash the firmware (always used stock firmwares), somehow it broke the efs mount point or something and now is says "Failed to mount /efs" in the standard Samsung recovery mode. It is still on boot-loop, with no root access, no USB enabled, and no OEM allowed to be installed, so I am in a bit of trouble, can flash a non-stock and I don't really know what options I have.
I bought it overseas so Support says they won't help me.
Any Ideas?
Thanks

Hello,
Earlier this week my nexus 5 refused to boot after i powered it down while at work. The phone begins to boot up but hangs at the spinning colored circles, i have left this over 24 hours and there is no change.
The device is stock and unrooted, I have tried a factory reset from recovery mode which completed OK however did not fix the problem.
At this point i would of normally just RMAd the device however i bought it on amazon, and the seller appears to have imported it from Hong Kong, so there was no valid warranty for me to claim under. Lesson learned there for the future but not a great help for me at the moment.
Because the device would still power up and since the warranty was already invalid i decided to try flashing it to factory. I unlocked the bootloader and flashed a factory image to the device in hopes this would resolve the fault but again just had the same results, I am however totally new to doing this so may have made a mistake here, but from what i can tell i followed the process correctly as i did not receive any errors.
The phone still boots to the same point, and i am still able to access the bootloader, is there anything else you think i can try or is the device bricked?
Flash the factory image with fastboot. See this, http://forum.xda-developers.com/showthread.php?p=47156064

So i attempted to flash again, followed method 2 on the linked post this time.
It all appeared to go through OK until i came to do the final factory reset when i noticed an error on the screen this time.
E: failed to mount /cache (invalid argument)
E: failed to mount /cache (invalid argument)
E: can't mount /cache/recovery/command
E: failed to mount /cache (invalid argument)
E: can't mount /cache/recovery/last_locale
locale is [(null)]
stage is []
reason is [(null)]
After running the factory reset and rebooting the phone it is still stuck at boot
So today after reading around I've found a number of people with similar issues that made some progress by reverting to Kitkat, so i re-flashed the phone to 4.4.4.
The phone now boots up again however i have no reception at all, Google Play store and the camera also appear to not work. All other functions I've tried seem to be OK so there's at least some progress.
I let the phone update back to 5.0.1 but just ended up not booting again so i downgraded once more.
I would be perfectly happy to remain on 4.4.4 so long as my phone actually worked, but at the moment nothing I've tried has managed to correct the lack of reception. I've not found anything online to solve the problem even though some people have mentioned the same issues after downgrading.
Can anyone point me in the right direction?

Indeed he is! :good: Saved my phone too. I had the exact situation as you http://forum.xda-developers.com/goo...p-lollipop-t3098632/post60491129#post60491129
I am wondering though: In my case the error I got was "failed to mount /persist" , and bitmodo's guide is exactly for that. In your case it was the cache partition. Is there a different command to fix the cache partition?
Hi all,
Long-time lurker - used info here ages ago to mod a tablet, but right now I'm working on my fiancee's phone, which is an unrooted Galaxy S7.
Yesterday, her phone took a complete **** out of nowhere. It spontaneously rebooted, said it was applying an update, and then the Android dude fell over with an exclamation mark next to him. She had just finished recording some audio that she *really* wants to get back (a press conference she got into at Comic Con).
The message now on the phone is:
Phone storage corrupt
The data partition has been corrupted. You need to reset your phone to factory default settings. This will erase all your data.
I've tried to connect to Windows and I can't get at the device - I have no way to change whatever connection mode it's going into by default. I've also tried getting into the phone through ADB, but the device isn't recognized.
I could really use some advice here
Anyone?
Thanks,
-Jeff

Reboot into recovery/download mode and see if you can access adb. If not flash stock firmware in Odin (Not csc, as that will wipe data)
If flashing stock works, I would flash stock again after you get the data you want (including csc the second time)

Eek. The data header gets marked as corrupt when this message appears. Chances are it will reappear after reflashing and because Samsung encryption is proprietary it will be hell to recover. If Craz's suggestion fails you may need to chalk this one up as a loss
Hi, i have samsung galaxy tab 2 (P5100) with no root. It started to restart 5-10 seconds after android starts... (i dont have time to go the settings or to do something before restart).
I tried to clear cache and factory reset from recovery but it doesnt work. (in recovery it shows done but when i reboot system, no changes are made)...
I also tried to flash new stock room with odin but it failed every time ( i use different versions of odin, different rooms and different pits). it fails after NAND write or system.img.
Im also not able to flash new recovery... in odin it pass but when i start recovery mode there is no change...
Does someone have similar problem? Im afraid that it could be problem with motherboard or memory.
In recoveory i see this error:
# MANUAL MODE #
--Appling Multi-CSC...
Aplied the CSC-code : ORS
failed to compare '/system/csc/common/system/app/MH_10_TCS_Tablet.apk' '/system/app/MH_10_TCS_Tablet.apk' (no data available)
Thank for any help.
Your tablet may have the emmc bug, sorry but only a mother board replacement or emmc firmware update will fix it
Same problem, not yet solved.
I also have a samsung tab 2. We bought it around 2013 and started to have problems around 2015. My device started to reboot out of nowhere, infinitely, randomly. I tried to look for patterns. Couldn't find any. But i noticed something, it's stuck on it's current state. When i do things like install an app or take/delete pictures, when it restarts, everything i did would be gone and it's back to it's "current state". App that i installed? Not there. Pictures i've taken? Gone. Pictures i've deleted? It's there again. Even a hard reset won't do anything. When i do a hard reset and it reboots again, guess what, back into it's "current state" again. I've read about it on some forums, i think it's hardware related. Emmc. A notoriously bugged chip, where when you clear your cache or flash it with a new os or something like that. Boom! Brickbug. I tried sending it to the samsung dealership where i bought it. They checked it. They said the motherboard needed to be replaced, which was very expensive. I'd rather buy a new one. Now it's 2018, i'm hoping they've found an alternative to fix this tablet.
Just realized i posted this in the wrong area and I'm not sure how to delete. Phone is a galaxy s7 edge. Sorry.
So i rooted my phone, deleted something i shouldn't have, then had to use odin to fix it after i got stuck in a boot loop (i think i used this: G935AUCU4BQF3). The phone starts up, says there was an authorized attempt... etc, ask for a wifi connection, then gets stuck on checking network. I bought the phone in the US, but I am currently living in China. I have tried 3 different wifi connections, and tried using a VPN.. but it still hangs. I have also tried wiping cache partition and wipe data/factory reset in the recovery. I believe i was originally on whatever update came out in November (i think i remember my phone doing an update). Any help would be greatly appreciated. I have been looking for a solution for 3 days, and have yet to come up with anything. Asking for help here was my final option.
There's been a couple of other members with the same problem, unable to connect to enter Google credentials and remove the FRP lock
Not sure if a solution was found but if you search this Q&A forum section you should come across a couple of threads about it
Hello everyone, first of all I want to apologize for my bad English, I'm Argentine.
I'm in a serious problem that I've been trying to solve for a year now. First of all, my cell phone is a Samsung Galaxy Ace 4 Neo, which I tried to install an unofficial rom based on CM13.
This is where everything began. When I flashed the rom, I accidentally disconnected the USB cable, causing my phone to completely crash. Determined to recover it, I had already installed the TWRP. When I proceed to want to format everything, the /system, /data and /cache partitions gave an error when being partitioned. So I stayed for 2 weeks until I visited a forum (which by the way, I do not remember what it is) that said that changing the ext4 format to exfat would allow you to format well. SERIOUS MISTAKE IS MINE WHEN TRUSTING IN THAT FORUM. By doing this I not only screwed up the phone already, but it did not even turn on. As a last resort, I used Odin to nand erase and reflash the stock rom. Surprisingly, there were no errors when reflashing, but when the phone is turned on, it remains in the boot screen. Investigating Odin's options, I realized that I can not use the re-partition option, since I get the error "Can't open the specified file. (Line: 1831)". I do not know what else to do with this phone, so my last hope is you. Please I need help!!!
