Persist partition permissions and owners - ONE Q&A, Help & Troubleshooting

Hi everyone. Got a bootloop, so had to format the persist partition. I made a backup of it with adb before formatting, but forgot to save permissions/owners of every file.
Could anyone just make an "ls -l" in all folders of /persist? Thank you.
P.S. I'd appreciate if anyone makes a full image backup of /dev/block/platform/msm_sdcc.1/by-name/persist
To make it, just do a dd if=/dev/block/platform/msm_sdcc.1/by-name/persist of=/sdcard/persist.img and post the file on any file hosting.

Why don't you just try doing a factory reset after bootloop?
Anyways,here's the file that you were asking for-

Because it was a bootloop just right after a flashed the ROM on a completely clean factory reset device. Now I understand that it was a problem with the ROM, that's why I made a backup. And your image will help me know if I miss any files in this partition and know their permissions.

hyperUnicorns. For some reason any build I try to install since the end of June gives me reboots. I thought it was some incompatibility with Multirom 33e and MIUI, but after I flashed the full Cyanogen package, nothing changed, that led me to google and some posts, saying it can be a damage of persist partition.

That rom worked fine for me..maybe it doesn't support multi-rom.
I think you should ask on the rom's thread.

[Q] Tried to format /data with CWM, E:failed to mount /data (Invalid argument)

Hello,
I recently rooted and installed a custom ROM CM10 nightly onto my transformer, and proceeded to wipe data as normal. I went to do it, and it was taking a long time, 5-6-7-8 mins passed and I thought something is wrong. So I force turned it off. Not that all it said for that time was "formatting /data..." or something.
Well, it failed to boot as expected, so I tried wiping again with no luck. Went and flashed TWRP recovery and it's showing errors:
E:Unable to mount '/data' (tw_mount)
E:failed to mount /data (Invalid argument)
I'm not sure how to proceed due to lack of knowledge. I noticed there's a file manager and terminal on this recovery so perhaps it can be fixed using those, or ADB or something.
Either way, I would like to request help from the TF300T community.
Thanks in advance,
Kris
Problem solved. Made a new blob without the bootloader included and flash it, then the system told me the data was unreadable and it fixed itself after that.

Greetings. I did, so far as I can tell, this exact same thing. I feel like I'm taking crazy pills.
Kind of wandering if someone put a "wipe data" label on the "destroy your transformer" button by mistake.
Can you please elaborate on what you mean by "made a new blob without the bootloader included"?
Are you meaning new zip without the boot.blob? I'm tripping over the words. Or maybe I simply do not understand what you are meaning.
I would be so grateful if I could get anywhere with this.

I don't remember the specifics, but are you familiar with using fastboot to flash .blob files? You use this to flash the new recoveries over, etc. First off I used the blob tools I found around here to extract the various parts of the stock blob I got from the ASUS site. After that, I rebuilt it simply containing the system and the kernel. Then I flashed that .blob file to the device, and it decided to boot up and tell me my data was ruined and gave me the option of fixing it. So, I let it fix itself and that's how I got out if it.

i had the same problem during flashing cm10 on my brandnew tf300t.
the system could not mount /data...
...solved this problem with the "wipe -> format data" command in TWRP.
sounds too easy?
How can you Wipe Data, if the /data isn't/can't be mounted?
I'm having this same issue with my RazrMaxx...

Well, in my opinion, I think the rom wasn't readable or working. If you have taken a backup before flashing the nightly rom, you can restore it.

[Q] WifiStateMachine: Failed to load driver

After formatting /system (via CWM) and installing CM11 the WiFi on my I727 fails to turn on. CatLog reports "WifiStateMachine: Failed to load driver".
I've read in various other threads that an Android device's /persist directory should have the driver files, but that directory is empty (did "ls -l" through rooted shell). Would anyone be able to post a listing of that directory from their 'rocket or otherwise provide some insight into what is going on here?
Thanks,
INCANDE

I think you should not format /system. I have seen this causing problems to other devices too.. I suggest you to try flash a ROM without flashing /system.. You can either do factory reset and wipe all cache..

Thanks. I have to admit I've heard the same thing, but I did so to rid the device of GApps (including Google Play/Services). I'd be curious to know of a better way of accomplishing that.

+1 or if you've already flashed them and want to get rid of them just delete 70-gapps.sh from /system/addon.d and re-flash the ROM.

Possibility to return to STOCK ATT ROM after KDZ flash of PR version?

I'm noticing that FlashFire has the option to backup the system parition file based. I'm wondering if someone who has flashed the PR ROM could simply do a restore of a STOCK ATT system partition backed up this way and if it would work? If anyone wants to try, I can make a backup and upload it and post a link.. Let me know!

Yeah.. probably right. It was real late when I posted that LOL
Actually doing a system restore via file based shouldn't hard brick the phone. Only if it was raw based possibly, but either way it would only be the system position so the kdz/tot would still be able to be flashed to the phone as before. This might work! Or at least be a good base to try.

I agree with this theory. It should only flash the system over the system. You would have to make sure the boot loader is correct for the system rom. So say a 10b bootloader for an equivalent 10bPR rom.
(If any of the above is confusing or slightly off, I blame it on the fact I have been battling a bad virus this week with a bad headache.)
I just warrantied my PR rom device a few weeks ago, or else I would have tried this for you.
Edit: You would also have to edit the script in the file to flash to designate the correct partition to flash the system to.

Unless it just extracts the tar'd files it copied from the system partition of the stock device. Still some ambiguity regarding that app. For example, it shows no option to allow me to make backups on the external SD card...

I would think it still needs an address as to where to put the extracted files.
I will look and see if I have any twrp backups on my computer from some of the roms I made. I have never fully looked through and studied the backups as much as I used them for system dumps. It just seems to make since that the recovery would need to know where to write the system files. Just flashing an app is alright without the address.
In writing the flashing script for ROMs, I have always had to give the recovery the address as to where to write the system files or else it would result in a flash failure or soft brick.
I may be writing my scripts wrong too. I just know what works for me.

How to Install Gapps ? (/system and /data on sd-ext)

My mmc got fried while formatting my /system and /data partition using twrp, so I moved my /system and /data partition to sd-ext partitions which I made using 4EXT recovery using delta-roh Turbo-DATA mod.
Here is what my partitions look like
1st partition -> SD-card -> vfat
2nd partition -> sd-ext -> /system -> ext4
3rd partition -> sd-ext2 -> /data -> ext4
Currently I have cm-11 by Ivanich on my phone but cant install Gapps. I ve been editing the update-binary in the Gapps zip but it always returns me the error that
"This Gapps pkg is for android version 4.4.x ...... Your rom : 2.3.7"
But I have a kitkat installed. I am guessing that its not reading the build.prop correctly. So how do I install Gapps ?
Any help is appreciated ...
More info about my phone
S-off
Bootloader unlocked
Rooted
Recovery : 4EXT
Rom : CM-11 by Ivanich
A recovery with modified ramdisk might be necessary. Maybe @hinxnz can help you with that.
Ok. Can i use the android kitchen to unpack recovery.img and modify it ?
If yes what modifications do I need to make it work ?

Yes you can use AIK for recovery image, you'll need to modify fstab like you did with the boot image. I have never unpacked 4ext though and it's a bit outdated now but I've always used ivanich's twrp builds when modifying recovery.
Otherwise you could just modify the updater script in the gapps package to not mount data etc but this will have to be done every time.
Edit: I just read your first post and I'm not sure how you even flashed ROM if your system partition is bad, did you modify the ROMs updater script to flash it to your new system on sd-ext or something? If so gapps could be reading your old system, then I'm thinking is it actually bad or just your data partition is...

Yep I modified the roms updater script to mount sd-ext as /system and sd-ext2 as /data.
I cant modify the gapps updater script because its just a dummy file and all the code is in update binary and it needs some experienced programming .
I ll try modifying the recovery's fstab and post the results.
"/etc/recovery.fstab" is that the file I need to modify ?
Edit:
I also tried adding the gapps to the rom zip itself and flashed it but that made the rom useless because it kept rebooting.

Just open update binary with a program like note++ if using windows.
I haven't modified recovery for a little while and haven't got the files in front of me but there are a couple to modify to get everything working, just have a peek round in the folders.

First I tried using the google installer to install gapps but playstore kept crashing so I ruled that out.
Then I modified the recovery.img and flashed pa-gapps-4.4 and it worked . The playstore was still crashing but updating google play service has fixed it, but I am not sure about this, gonna keep testing for a while. Atleast now I have gapps
Thank you very much

If you mean shutdowns then yes, otherwise if rebooting then it's something else.
If a full reboot happens, it will show in /proc/last_kmsg

[J710FN] need help, TWRP crypto footer and unmout data. (SOLVED)

Hi, you can see my question.
I've try wipe, but only data works. And no change.
I've try to réinstall the custom rom, you can see result.
Ttry to flash stock rom with odin, odin failed.
and try to réinitialise with smart switch ( he say me i havent tow slot for sim, i know). And ... nothing change.
The device has been already root, and i've already change for this custom rom with no problem.
Thanks for your help.
Edit: with format data after wipe data and after reboot on twrp, no red line, i've install the rom. good : i've the rom, bad : the problem is come back.
Just for to be sur, this screenshoot is just a example. Other installation make me the same error.
This rom work really good and other people haven't any problems.

do't worry it is normal i explain you
when you format with twr the data is readable
and the first time starting system Samsung encrypt the file so txr can't mount again data
but don't care about it

It's all because kernel has encrypted /data and data encrypts after a reboot. Some changes in the kernel solve your problem. Data will mount always after some changes in the kernel

When you flash anything that modifies or replaces the boot partition you need to reflash the patch afterwards or the data partition will be re-encrypted.
