Hey all,
I have an S4 i337m model. I've installed a custom ROM that is essentially a rooted stock ROM (I do not remember the exact build/version of the ROM). I realize having this info would be useful, but at the moment, I cannot access this info.
While running this ROM, everything was fine. Last week Friday, I attempted to install FoxHound 1.6. Had to play around with the installation options, but I got FoxHound to work. However, I need to get back on my old ROM as I needed some files that were deleted during the FoxHound install. So I wiped my phone, and restored my nandroid backup of my rooted stock ROM. again, everything was fine. No issues.
Here is where the problem is; after restoring my rooted stock ROM, I could boot into the phone and access the files needed. However, when I reboot/shut down phone, upon restarting/powering up, my phone is stuck at the 'Samsung Galaxy S4' logo right after power on. So, I boot into recovery (the latest version of TWRP) and I navigate to 'file manager' to take a look at my storage/files. And this is where I believe the issue to be; I see virtually no files at all. I can see many folders/partitions, but there are virtually no files anywhere (i.e. the system and data partitions are empty). I am assuming this is the reason why my phone doesn't boot past the Samsung Galaxy S4 logo. Now, when this happens, I wipe my phone again and restore my working nandroid backup. Everything works fine. I can get back into Android without issues. Until I reboot/power off my phone. Then this happens all over again.
I believe I may have damaged(?) the partition(s). When I installed FoxHound, I also installed an option during installation titled 'EXT4'. I know linux uses ext2/3/4 partition tables. Did I damage my storage/partition by installing EXT4 from FoxHound? Do I need to repartition my phone via Odin PIT file or something similar? Am I totally wrong with my analysis? Any help/advise/insight would be very welcomed.
Thanks
Additional info
Baseband: I337MVLUAMG1
Build number: JDQ39.I337MVLUAMG1
ROM: Rooted stock ROM 4.2.2 (with some bloatware removed)
While my phone was in the it's 'logo stuck' state, I entered into TWRP and selected the Wipe option, then Format Data. I must select 'Format Data' in order for my phone to work on it's next boot. Manually formatting System, Data, etc... will not allow my phone to boot up at next boot. And, my phone will only work on the next boot. If I power off/restart phone, it will get stuck at the logo again. So my phone is only good for 1 boot up after a wipe.
And, after I restore a working backup and boot into the phone, everything works until next power down/reboot. Once I power down/reboot phone, I must go into recovery since it will not boot into Android. When I get into TWRP, I see that my Internal Storage has 0MB free and I am unable to see any files. I can see folders/partitions, but there is nothing in any folder/partition. My external SD card shows nothing as well. My external SD card however is unaffected as all the data is still there once I get into Android and look around.
Also, I just restored a backup I had before I was having this issue. After restoring and rebooting, the same thing happens. I get stuck at the 'Samsung Galaxy S4' logo.
So I'm guessing there is some partition troubles here. Maybe I'm wrong, but I'm scratching my head as to the cause of this problem.
It could be some hardware issues too. I'd Odin back to stock and see if the problem persists. If it does its hardware.

I thought the same thing. I'm downloading the stock ROM now and will give it a try.
One other thing I noticed during my last restore/fix attempt... After I perform a wipe -> Format Data (from TWRP), I notice that it reverts to my rooted stock ROM without me restoring anything. So, after I do a full wipe/format, and reboot my phone immediately after the full wipe/format, my phone will boot into the rooted stock ROM. I thought that wiping/formatting via TWRP totally cleans the internal storage of all data. So how can I be booting into any ROM after a wipe?
Unless I'm mistaken in my thinking and the full wipe/format option in TWRP just reverts back to the stock ROM I had installed prior to installing further custom ROMs?
If you wipe system and data there shouldn't be any rom it would boot. Don't try that though unless you have a nandroid because it shouldn't boot
What version of twrp ate you using?
Do not format data in twrp.

I hear ya... I have several nandroid backups. All work (minus this 'stuck at logo' issue I am having). I am using the newest TWRP version 2.6. It's very strange... after I perform a full wipe, I am able to boot into my rooted stock ROM that I flashed shortly after acquiring the phone. This was a bit over a month ago now. I do not know how this is possible.

Use twrp 2.5.0.2 or cwm. The newer twrp has issues.

Is TWRP 2.5.0.0 ok to use?
Ok... It's really starting to look like my partition table has been damaged. Every time I flash a new ROM or restore a nandroid backup successfully, and then restart my phone, I get stuck at the S4 logo. Upon starting recovery, my internal storage reads 0MB free. It seems like my partition table is becoming corrupt after a reboot, or it has already been corrupted.
I tried flashing the stock ROM for my phone (I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME.tar is the one I used), but that didn't help at all. After installing this stock ROM, and I go into stock recovery, I get an error: E:failed to mount /data (invalid argument).
This really is looking like a partition problem. Is there some way to re-partition my phone? I remember a PIT file was used to partition my old Galaxy S i9000. Is there a PIT file for the S4 i337m?
I would also like to try CWM but I am having a hard time finding a ODIN flashable version.
I wouldn't mess with a pit file and I haven't seen one anyway. It's sounding more and more like your memory is bad. I'd keep it stock and see if you can get an exchange on the phone under warranty.
Further investigation has lead me to the culprit... sorta. It's my /data partition that is screwing everything up. If I format /data and then reboot, I can get into my phone. But if I reboot again, then my /data partition becomes corrupt and my phone hangs at the S4 logo. And then if I go into recovery, I can see that my internal storage is at 0MB free.
However, after formatting/restoring /data partition and rebooting into android successfully, everything works fine. If I reboot from this point and enter recovery, I am still able to see my /data partition and files. At this point, everything seems to be fine. Once I reboot out of recovery and let the phone boot into Android, I get stuck at the S4 logo and my /data partition screws up/becomes corrupt. It looks like my /data partition is only becoming corrupt after the 1st successful boot into Android. If I enter recovery after the 1st successful android load, I am still able to see all files and partitions. It is only trying to load android after the 1st boot that my /data partition becomes corrupt. Very strange...
So, I can always boot into my phone as long as I format my /data partition prior to loading Android. Anyone experience this before? Any ideas? I realize my memory may be damaged, but I'm leaving that as a last resort possibility since my phone was working fine up until I started installing FoxHound with the EXT4 option as well as installing 1 or 2 of the kernel's FoxHound provides. Namely Adam kernel is the one I tried.
All good... I think/hope
Well, I think I got the problem solved. After toying with this thing all day. It seems like TWRP 2.6 was the problem in some sense. Looks like TWRP 2.6 does not format the /data partition correctly. I had to get restore/install a working ROM, boot into my phone and install ClockworkMod Recovery via ROM Manager. I then used CWM to format /data. Once I did this, and loaded back into my phone, and went through the setup process since /data was formatted, everything was working fine. I just rebooted 5 times and shut down twice and my phone booted back up into android without issue.
So as one user in this thread had mentioned, formatting /data with TWRP 2.6 was the problem.
Hope this helps others avoid a similar issue.
Thanks everyone for all the help. It pointed me in the right direction.
Glad you got it fixed.
I'll be giving these steps a try, having somewhat of the same problem!
i've been having this exact same problem but with TWRP 2.5.0.2 since July. Its been driving me insane and I have not been able to find any one else having this issue until now. I think i might finally try CWM instead as a last measure before I finally give up!
Try TWRP 2.6.3.1 version. It works pretty well even though it's unofficial http://forum.xda-developers.com/showthread.php?t=2262996

Hey,
I've had this problem for ages now, and always gave up on my data, but now I really want to fix this for good.
Yesterday I was ready to update my CM12 nightly to the lastest version (didn't see it was actually CM13), and did a backup in cwm before the update. The backup succeeded, but it gave the message that .android_secure couldn't be found and it didn't back that up. It always gives me this message after a backup and after google searching, it seems to me that it doesn't matter.
After installing the update, I noticed it was CM13, and my gapps wasn't updated to the marshmellow stock, as expected, so errors occured all the time.
I didn't want to upgrade to CM13 just yet, so I decided to restore my backup.
As always, the restore process goes without errors, but upon reboot I'm stuck at the CM logo. I can wait untill the battery is dead or ignites from the heat, but nothing happens. This has also happened to me every time I make a backup. I've watched about every video on youtube on how to do a proper backup and how to restore one, so I'm confident that I did it right.
For some reason, any backup I make, no matter what android version (didn't work with stock kitkat, either, before I switched to CM12) it never works and I'm forced to do a clean install and start over again.
I've tried to do partial restores from the backup file, and if I only restore the data partition (and wipe dalvik) It does boot, but gives me non stop errors that apps are crashing.
I've tried to do a dirty flash to no avail, always endless error messages.
When I do a clean install and check the MK5 of the backup with nandroid manager it gives no errors.
Is there anything wrong with my phone or something? I'm not making backups to be unable to restore them.
Can anyone help me out with this?
(I have a i9505)
Try a different recovery. CWM is outdated. TWRP is nice. Worked for ne every time. There are TWRP flashable zips so you won't have to mess around with Odin.

Won't changing recovery make my old backups useless? I'm all for changing to TWRP, but first I'd love to restore my CWM backup...
Yes it will. Unfortunately I don't know what to suggest. Haven't used CWM since I switched to the S4.
Hi,
I've flashed TWRP for a sm-G900f via heimdall, booted into TWRP-Recovery, made an backup from the working Stock ROM to sd card, flashed lineage open gapps etc., all works well.
Because of somtimes not working Sensors I've tried to test if the sensor problem is an hardware or an software issue, so recovered the stock rom backup using the installed twrp 3.2.1-0. Therefor I've made these steps :
Boot into recovery
Wipe cache, system, davlink-cache, format data
restore the stock rom backup
reboot
Every reboot results in booting to recovery, Samsung system won't start.
Tried to disconnect battery for a few minutes etc.
Where is my mistake ? Could someone give me an advice ?
Every restore of the lineage backups using this way works well.
Regards
Fred

Corrupted backup maybe?
A long time ago I made a backup of stock and was able to go back and forth with no issues. You can try and go back to stock, root again and try another back up.
Corrupted backup ? It's the only one I've made after flashing TWRP and before installing Lineage.

It happens sometimes, I had an SD card with a bad sector so every time I would make a back up it would get corrupted if I deleted the back up. I ended up leaving the backup so it will no longer write on the bad sectors.

I think, you have to flash or restore the right kernel.
Which partitions have you backed up?
Sorry for the late response, the backup includes in my mind system, data and boot partition because the backup consit's of the following files:
boot.emmc.win
boot.emmc.win.sha2
data.ext4.win
data.ext4.win.sha2
data.info
recovery.log
system.ext4.win000
system.ext4.win000.sha2
system.ext4.win001
system.ext4.win001.sha2
system.info
Hi,
Am just a newbie in flashing roms and stuff like that. I have a note 2 GT-N7100 that was running 4.4.2. KitKat. I decicided to root the device and it was successful. Flash TWRP all went well. Then I tried flashing a custom ROM. I read about backups so I made a backup before flashing the ROM ViperOS 7.1.2. Flash Gapps and it was successful. But my Sim was not detected. So I retored backup and was back in 4.4.2. and the sim was detected. Unfortunately for me, my backup was in the internal memory of the phone. I thought the ViperOS was just faulty somehow not to have read my sim. So I tried a Marchmellow custom ROM from a site I can't remember. The phone got stock at Samsung Logo. I waited long time to no avail. Instead of clearing cache n dalvic I included internal memory and data. That was how I lost the back up. It took me to the stock recovery. I wipe data / factory reset. Still got stock at boot loop. I flashed TWRP via odin and it was successful. I flashed the viperOS it works but no Sim. I read through some threads and understood I lost my IMEI. I checked it was unknown. Baseband unknown. Tried a couple of proposed measures but to no avail. I thought the best thing was to go back to stock.
When I flash the stock, with odin it fail. I don't want to believe it can be cable or port issues since I flash TWRP successful. I tried flashfire. The flash completes bit it says "failed to mount cache. Invalid argument. Read that I have to mount and clear cache. Did all that with no success. For 5 days now. I really need help. Don't know what to do. Pls help me.
Thanks.
Am sorry for writing too much
im having big problems about vendor. for start im giving some info:
device: mi a1 (tissot)
current os: lineage OS 17.1
root: yes
twrp: can install or use just booting .img
i unlocked my device and installed twrp. there is no problem.
i wanted flash lineage OS and i wiped my device. gives error about cannot mount /vendor
i installed treble supported twrp and installed lineage OS. flashed magisk. installed microg...
then i tried flash mapsv1.zip which is recommended for microg. then booom. another /vendor error.
now i can boot device. i can use everything except gps. google maps app cannot found location. yandex maps can found and i can use it until lock screen or going main screen (or another app). then it starts stopping everytime until i clen its data and cache. then again... in chrome when i open google maps and try found my location chrome stops.
i tried to change /vendor/etc/gps.conf. its still same.
what to do now guys? im worrying about if i try re-flash rom it doesnt flash and device bricked. any solution without re-flash rom? what causes to cannot mount /vendor after solved it?
What exactly did you wipe? I think you wiped vendor, or bumped your O.S. from an old firmware. However, wiping system, data and Dalvik was more than enough.
To solve this, the worst thing to do is trying to hook around. Just reflash the latest original firmware and start again.
Keep in mind that you might need to backup your stuff first.
Use adb pull and push commands in case your device is rebooting too much. Check if device works well this time.
Next, open adb access from device and reboot fastboot to reflash your custom recovery, then reboot recovery and wipe just these items. Finally, complete Rom flashing procedure, depending of your needs.

Dalvik cache , system, data, and cache. My device is not rebooting too much. Sory if i couldn't explain. Everything working fine except when an app tries use my location, app stops running, i cant flash anything right now.
İ thought anyone knows mapsv1.zip file(microg.org) and which files are replaced or added by this file when flash it. And can i do it manually? Btw i can read and write /vendor file with solid explorer
İf needed to re-flash rom thats ok but i think lineage OS was perfect for me until this error. And a last thing: can i backup my settings. (İ already took backup of everything in stock when unlocked bl)
Thank you for help
Edit: gps problems started when i tried flash mapsv1
ROM could be perfect, but what I doubt is how perfectly you followed the procedure. Again, better start from zero, being sure you have all the prerequisites (latest firmware included). My humble opinion.

Okey ilk try it and share the result night. But is it possible to backup settings of phone?
Well, that's why in step 0 is always recommended to backup you phone. At this level you should have nothing in settings, since you wipe it all... However, that's better, that's the goal of a Clean Install after all. Each ROM has its own flavour and is not recomendable to overwrite these values from a backup, if you're changing ROMs. What you could do, was to backup your apps and some settings with a third app like Swift Backup, or older Titanium Backup, before starting it all, or else, making a complete backup from recovery, in case you end with a problem with newly installed ROM (recommendation here is disable any screen security lock before doing Backups).

İ did it all. Step by step. But i realized something. That errors doesnt matter on my device. Bcs when i flashing stock mi flash tool said failed but i booted system and everything working fine. İ installed persistent twrp. Same error. Then wiped. Same error but wipe completed. Than i flashed this zips single and booted everytime: lineage os, magisk, backup of migrate. Everytime it said cannot mount vendor but all of this apps and os and recovery working fine
Thank you for your helps

if you didn't treblized your device then its not a problem. I have this error too but that's because there is no vendor partition to mount. as been said by unipo:

Are you sure? Bcs i can view and change /vendor in root path. Treblizing is updating and repairing system partitions right? İ am using treble support twrp, flashed stock rom via mi flash(said error but worked fine) then how to treblize a device? And is this required for anything(like a rom, an app)?
