Trying to set write permissions on /system ends in bootloop

hi,
i did a big mistake. I wanted to install some vpn apps, which requires write permission on /system. I downloaded root explorer und tried to set all permissions for the system folder. But the app stills lacks the wanted permissions, so i started root explorer again and additionally checked the checkboxes under "special permissions". After doing that android crashed, the "systemui" process crashed and restarted and crashed ...
I rebootet the device, but i only see "google" and then comes a reboot and the device boots into recovery (TWRP 2.6.3.4). I already tried the "fix permissions" under advanced, but it didn't helped.
Is there any way to fix whatever i did wrong and not lose any data?
Any help would be greatly appreciated

Thanks for your help. I don't want to miss something this time and complety brick my device. Could you/anybody tell me exactly what and how do flash to recover my device?
I did all the rooting stuff with the "Nexus Root Toolkit" program and followed strictly guides, except this time
Do i have to flash the rom with ADB? which file(s) should i flash system.img only? Or i have to flash more files?
A short noob guide would be really appreciated :good:
Greetings k1x1987

So you are just rooted on the stock setup? Then you should be able to flash a stock odexed rom that matches your current set up (4.4.1 or 4.4.2) and you should wipe, but just the caches. You'll likely need to adb push rom.zip /sdcard when in recovery. You probably could adb sideload as well, but not sure if that wipes anything else. Never had to mess with sideloading.
For future reference, once you are up and running, I think what you would need to change is the SELinux permissive state. There's an app do that. Then the most you would need is to hit the R/W button when you're in /system with Root Explorer. Or with the newer Root Explorer versions, once you try and make a change that needs R/W permissions, it'll stop and ask you if you want RE to switch it for you to complete the task.

Thanks for your help. Yes, i am complety stock besides root and franco kernel. I already downloaded factory image (4.4.2). Should i flash the zip, which contains all the system.img, userdata.img etc. (i think it was 5 files) or just specific ones? It would be n1 if my data dont get lost.
Thanks in advance.

Just flash the system.img in fastboot.

Most devs recommend wiping /system first.
fastboot erase system
fastboot flash system system.img
I would also erase cache too.
fastboot erase cache
That will clear the cache, not the dalvik, but think that should be enough to get going.

...and once it is fixed, never change system permissions again.... Same a Linux, never change permissions at /root

.. phone works again
thanks at all for the help. But now i cant get any cell service. I looked under settings/about the phone/status and saw that my "IMEI" is "unkown". Could this be the problem? I read about restoring imei, should i try this and it this the cause for me not getting any service?
Thanks

Using fastboot, flash the cache image from the factory image, fastboot flash cache cache.img

^ That should do the trick. If not, well, let's not go there yet. The cache should fix it. If that does, do yourself a favor and back up your EFS folder and save it somewhere safe. Either use TWRP or flash the EFS backup tool from here: http://forum.xda-developers.com/showthread.php?t=2514095

CWM Backup file

Hi all,
Just wanted to know where the nandroid backup from cwm gets saved? It says sdcard/cwm/backup .But there's no folder such as backup in the cwm folder, although it shows up in recovery mode (the backup file). I was hoping I could find the file and move one of them to my PC so as to save some space on the phone.
Any help would be appreciated..
Thanks

I just backed up my N5 with CWM and I can't find the file... I tried all locations shown here with ES file explorer and these dirs are empty... Or at least they show empty.
Any idea what I'm doing wrong?
N5 - rooted - Stock rom - franco kernel - CWM recovery

After a backup has been taken, does the storage show less space available?
How about taking another backup and see whether it's working or not?
PS: Instead of CWM, can you try Philz? It's based on CWM with added goodies! I find it a lot better.

Figures. I thought it wasn't showing hidden files even though I checked the "show hidden files" box.
Clicked "Root Explorer" and lo and behold, there's a **** ton of stuff in there.
This was driving me insane (and filled up my storage too grrrrrrrrrrrrr), thanks rootSU.
Ok one last question, is there a way to view all files in windows as well when the device is connected via USB?

No probs

[Great Trouble] Apps stopped

[My first post on xda, plz help!]
My N5, 4.4.4 not rooted, has faced those problems for about a month or two:
1.My gallery force stopped when I tried to use the default gallery photo editor (the little pencil button at the left corner of the screen) to edit a photo of any format, but luckily I still have Pixlr Express and Photoshop to edit photos, nevertheless, it is still uncomfortable to see. ?
2.My YouTube and YouTube studio app also force stopped when I tried to share a video. It is very troublesome to me as I need to share my videos for promotion! ?
3. My Instagram also force stopped when I tried to choose a picture from my gallery in the camera page of the app. However, when I go to the gallery and directly share the photo to Instagram, it works. It is kinda strange.
4. It is a terrible problem and limitation for android users, but still not the worst for me (you will see when you read the next bullet point). My phone can't install apks! I have no screen filter and the install page doesn't even completely show up as the package installer stopped message comes up ahead of it.
5. The worst problem of all... Settings is malfunctional, I can't force stop, or clear cache, or change default settings of the apps because when I go to the list of apps and tap one of them, "Unfortunately, Settings has stopped" message jumps out and I am never able to solve the problems of the apps above. What's more, when I go to "About Device" and keep tapping on the Android Version 4.4.4, the easter egg animation doesn't show up! ?????????
So, this is it. I plan to factory reset my phone but I am not free to back up my data yet, so would it help? Additionally, one more piece of information may help you guys find out the clue: I have a File Manager that can open folders over the sdcard folder (I am not pro so I can't explain well) so I can access to system folders containing things like system apps, boot animation, kernel etc. So is it abnormal for a unrooted phone?
Hope that some of you can help me. ???

No... Its not abnormal for a file manager to view system folders... U can't edit the folder nor can you see contents of other folders... Actually just boot a custom recovery and wipe data without wiping the internal storage... It may solve the issue... To do that use towel root method of rooting flash the custom recovery using some app or unlock the boot loader using bootunlocker apk...

Then in case you are a noob just go to boot loader after downloading the recovery image as well as adb drivers and use command fastboot boot name of your recovery.zip or fastboot flash recovery nameofrecovery.zip...

you don't need to root your phone and flash a custom recovery to wipe data. 1. you can do it in stock recovery 2. you can do it in the main settings, backup and reset(factory reset).

Because N5 doesn't have removable SD card... In phones with SD card also, the internal storage will be wiped and only the SD card is left alone as it gets unmounted on power off...

By the way, if I ignore these problems now and wait until the android L update, will they be solved after the update? I am. using stock android, no root.

Just fix it. Pretending it doesn't exist and hoping an update fixes it gets you nowhere. Copy your SD card to a computer, and wipe it. Just do it. Stop putting up with this crap.

Thx, I fixed it now (temporarily) by turning to recovery mode and wipe data.
However, before I did so, I used the factory reset in settings and when it came to erase data, the 'erase all data' button had no response, it is weird. But anyway the problem has solved ?

FYI you could have used ADB to back up the phone data.

so, deleting data in the stock recovery did not wipe your storage?

need help - how to copy TWRP nandroid backup to device?

how to copy TWRP nandroid backup to device?
I need to restore and I don't know how to copy from my hdd to the phone.
The phone is not booting but I can get to twrp recovery.

Latest TWRP has MTP mode.

but it doesn't allow me to copy one of the backup files which is: data.ext4.win000 and it's 1.5GB

You'll need to give us more information.
Why did it fail? Why did your phone stop booting?

1. flashed bigxie_hammerhead_LRX21O-signed.zip
2. flashed CF-Auto-Root-hammerhead-hammerhead-nexus5
3. booted fine but still had apps like Ti backup & TWRP not working due to root permissions
4. Went to recovery and performed Fix permission.
5. stuck in boot loop

I have had the same problem with my motox 14 the way I found around it was to copy the file to a different fold and use twrp file explore to move it to the back up folder. That has worked for me and a few others try it out it will work.

how can you copy using twrp while in recovery? are you able to access your PC from recovery?

You'll need to factory reset then reflash the ROM
Fix permissions was not required here. You need titanium beta from his twitter feed.

ok i got the phone working and lost my data but I have it backed on PC.
I just see that 10GB is used but when I browse the phone using file explorer, the device is empty.... what??

Is it a known issue?
when the phone is connected to PC I see that 10GB is used but when I i browse the device it shows as empty

No. Do a full flash of userdata.img

Well the answer in the 100 other threads about space say that you must wipe data and cache.
Root should be fine, but as already mentioned, not with official titanium release.

I already did a wipe data and cache. So I don't understand why I still get this but I'll try again.
The Ti Backup link in the twitter feed is no longer valid, but for example, ES file explorer and clean master and also TWRP app are not performing as if they are rooted.
I'll try to re-install CF-Auto-Root-hammerhead-hammerhead-nexus5

ES doesn't work properly, correct. Not all apps have been updated to work with L yet either.
L is much more secure than KK. There are ways to root.
1) chain fire - makes small change in RAMdisk that allows sudaemon to work at boot
2)flash a permissive kernel - this lowers protection within selinux.
More apps work with the 2nd method, but still not all.
New titanium coming to play soon.

[H918] TWRP Flashable Stock Firmwares

with little to no activity lately for the LGV20, specifically the H918 T-Mobile variant I decided to look into creating a TWRP flashable package for the recent H91810k release. these zips flash every partition included in the latest KDZ package with the exception of recovery to keep TWRP. standard disclaimer applies, you do all of this at YOUR OWN risk! I've tested this on my device after backing up and so far so good on the latest 10k release. please report back in this thread on whether it was successful or not.
NOTE: you can find the partitions that will be flashed in the updater-script. to be extra cautious you can back up all of the partitions that will be overwritten with the following: dd if=/dev/block/bootdevice/by-name/{partition} of=/external_sd/backup/{partition}.img.
Instructions:
download H91810k.zip file listed below and put on microSD card
backup any data from internal "SD card"
boot into TWRP (requires TWRP recovery to already be installed)
create a TWRP backup of the device
flash zip from microSD card by using "Install"
flash your choice of root, either Magisk or SuperSU *Note: v12.0 of Magisk does not work with the LGV20 device in general and v11.6 is recommended.
reboot
profit!
Download:
H91810k
md5sum: ab181ec82315b656a7af48f0017f4e8c - version 1 with misc partition included (SORRY)
md5sum: 8ad07ae70c4299b3ea6e2bf747dbec1c - version 2 with misc partition removed
Flashing Process:
flash necessary partition images with the exception of recovery (to keep TWRP) from the KDZ
rename /system/recovery-from-boot.p to /system/recovery-from-boot.bak to prevent stock recovery from being installed on boot
wipes dalvik-cache and cache
BIG thanks to @McNutnut on guidance, as well as his script to put all of this together!
also thanks to @bullghost for the KDZ extractor (https://forum.xda-developers.com/showthread.php?t=2600575)
@Tilde88 for the original updater-script template w/root (https://forum.xda-developers.com/v20/development/us996-nrd90m-modded-notsostock-rom-v5-1-t3526542)

First! This is sweet!

I just tried this and it works great. I prefer to use the stock rom and to get a rooted 10k that doesn't have any known security vulnerabilities is awesome. Some notes for others:
Copy SuperSU to the external SD card and flash it after this zip in TWRP.
Make sure to select all the partitions for back up in TWRP.
On the first boot after flashing, the phone will reboot by itself. This is probably normal. You will get an "Android is upgrading..." white screen. This is expected since the cache was wiped by the script. This will take a while to complete. Even when you get back into the system, an "Android is upgrading..." message will appear in the notification bar.
Clarification: The data on /sdcard doesn't get wiped, but it's a good idea to back it up just in case. The TWRP backup of the data partition does NOT include this stuff in the backup.
I had Busybox installed before, but I didn't have to reinstall it after the flash. I'm not sure why. I assumed that wiping out system would have required me to re-install Busybox. I guess Busybox doesn't get installed on the system partition?
Adblocking using apps like AdAway need to be rerun since the hosts.txt file will be reset.
Ignore the stuff under "Process" in the OP. It's explaining what the script does. You don't have to do any of that.
The script disables the updater software. You never have to worry about the next stock release causing you trouble!

You did something other than flash the rom in this thread. Maybe you're confusing this thread with this one? https://forum.xda-developers.com/v20/how-to/t-mobile-lgv20-h91810k-kdz-t3618021
If that's what you flashed, you will definitely end up with stock recovery and no root.

I've tried to install this ROM but it skips through each of partition rather quickly and it never installs. I'm on H91810j with root and TWRP installed. Any ideas? Thanks.

Can you provide more detail on what you did? You made a pretty strong statement that you lost TWRP.
Did you follow and flash what was written by the OP? Did you do flash something else after flashing what was provided by the OP? Or did you really have TWRP the whole time?
Not looking to cause an an argument but your 2 posts in this thread have made me hesitate flashing.
