I've been using CM11 nightly on my i9500 and probably due to a lot of **** I'd done to this phone recently it has become quite unstable so I decided to wipe everything and do a clean installation when I remembered there's a way to enlarge internal storage up to 11.8G by flashing PIT, BL, AP, CP, CSC from I9500ZCUCMG1.
And I tried and it failed. So I only flashed PIT. Then I tried to flash BL and I see "SW Rev. Invalid magic string." on my phone. I googled it and it seems to be that Odin doesn't allow flashing an older version of bootloader. So I tried to flash I9500ZCUGNH4 but still fails with messages like "sboot.bin", "NAND write start fail".
Then I tried to flash a regular PIT provided here: http://forum.xda-developers.com/showthread.php?t=2269941
Then I tried to flash I9500ZCUGNH4 again, and this time it works. However when the device try to boot, it stuck at logo. I tried to go into recovery and it says:
E:failed to mount /data (invalid argument)
can't mount '/data'(Invalid argument)
E:failed to mount /data (invalid argument)
can't mount '/data'(Invalid argument)
Now I ran out of ideas and came here for help. Help plz. Thx in advance. :crying:
Almost forgot, I did a FULL 14.6G backup (probably all partitions) using method from this thread: http://forum.xda-developers.com/galaxy-nexus/general/guide-phone-backup-unlock-root-t1420351
Is there any way to restore it now?

If you have old twrp backup of any rom which is earlier(in yout mobile not other mobile only your mobile don't try backup of other mobile if the mobile is same then also not try only your mobile backup) then to goto twrp hit restore and restore efs only
Or try to reflash ypur rom using this method
Use this method
1- swithoff your galaxy grand 2
2- power on to download mode( volumedown+download+power)
3- open Odin choose tar file(stock framware)
4-(most important) unmark auto Reboot, mark F. Reset time & Nand Erase All & phone bootloader update & phone EFS clear. see attached image
5-connect your grand 2 to your pc it will be shown in odin like com?
6-start odin to flash firmware to your grand 2
7-when odin finish don't reboot just remove battery for 20 sec.
8- re-insert battery and power on in recovery mode( volume up+home+power)
9-leave it do its work till samsung logo appears on screen remove battery again.
10- re-insert battery power on to recovery mode.
11 - in recovery do factory restore twice then reboot.
You can download the firamware from samobile google it and search for girmware of your model number with country code of country
Hope this will help you

Or box of your mobile and its bill

PLEASE HELP WITH THE FRP LOCK WITHOUT BUYING A BOX
this is seriously affecting my business and cutting into my playing Destiny time!!
thanks in advance Mike
This all happened when my phone got drained then when i charged it and tried to open it, it got on bootloop. So i flashed another rom wiped all partitions then rebooted to twrp then this errors are present
Failed to mount /data (invalid argument)
Failed to mount /system (invalid argument)
Failed to mount /cache (invalid argument)
And in the twrp on install>select storage my internal storage shows 0mb.
Tried reverting back to stock rom but after i relock bootloader then flashed stock recovery it leads to usb logo, so i unlock bootloader again to see and access recovery and it directs me to twrp like i didnt flash anything
Need help or my phone is dead already. Thanks its my first thread btw
Well I screwed up somewhere. I tried updating my modem and then it got stuck bootloop and now i keep getting that error in twrp no matter what I do I tried to return to stock but twrp can not find the restore as in this guide https://forum.xda-developers.com/le-pro3/how-to/guide-return-to-stock-lock-bootloader-t3539513. I tried flashing everything Manually except system.img as in this guide. https://forum.xda-developers.com/le-pro3/how-to/guide-how-to-manually-upgrade-firmware-t3609786. Still no dice. I'm unfortunately stuck and can't figure out how to fix this. All i have acess to is TWRP which always gives me that error Failed to Mount '/firmware' (invalid argument) and Fastboot. I'm sorry if this isn't posted right. I tend to not post very often. Thank you in advance My device is X727
Help! My phone is now stucked on a boot logo. I tried rooting and flashing via odin on Oreo, after then, it stucks on boot loop, on which I know how to fix, going back to stock rom works, but then signal is gone (boot loop wasn't expected, didn't managed to see bandbased version) I then, flashed this: https://forum.xda-developers.com/showthread.php?t=2420881 through odin via AP, which is a wrong method on which I know I am stupid enough, right after then, OS won't boot up but stuck on boot logo, also tried using TWRP and Official Lineage OS 14.1 and the same thing happened, it starts to boot up, it rebooted after a few mins, then it goes back to TWRP.
HELP, I think the wrong method of flashing of this: https://forum.xda-developers.com/showthread.php?t=2420881 file is the mistake, idk what did I messed up with it, it was supposed to be used for EFS restore app not flash through Odin, what should I do? Any OS just stucks on boot logo but download menu and recovery mode (official/twrp) is still there, also the phone is still viable to be flashed.. Please help.. I just got this phone not even 24 hours ago.. Lol, I know stupid me, that I didn't checked the file carefully, I learnt my lesson, criticize me or anything.. But please, help if you can.
I had not known that the Marshmallow, Nougat and Oreo was pretty harder to do things on, I'm quite new with this new OS release, I was pretty confident because I was doing this all over the years (I only know step by step, not really in-depth information). Way back, odin only requires AP, now it requires 4 columns on which I cannot reflash without unchecking the Bootloader.
P.S. Before boot loop starts to happen I tried rooting on Oreo, downloaded my own country region openline version(I am openline, yes) and also tried Lineage OS 14.1, Now, I am trying to download Russia(not my country) Stock Rom Oreo, it might be the case that it doesn't allow me to flash bootloader as this was the downgrade, and I skipped right through it. But I am worrying about the wrong flash file and after the download finishes, the same thing happens and I won't be able to get passed out of boot
EDIT: I've did everything and ODIN works for the flashing the whole columns including bootloader with russian full stock ROM, but its still stuck on boot logo, EFS not detected on recovery. I'm losing hope, this is not recoverable yeah?
Here's the error code on recovery mode:
#fail to open recovery_cause(No such file or directory)#
