LG D620r bricked - LG G2 Mini

Hi, I have tried many times to edit the /system/etc/mixer_paths.xml , but when i saved it I change permission of system, and i unchecked the last one, now i cant run my phone and in twrp options there is no os. I forgot to make a backup. Can someone help me ?

In TWRP's file manager, choose the file and press chmod 755

[Q] SGPT12, modified build.prop, won't boot anymore!

hi,
I still have adb access,
already tried to adb-push of the original build.prop backup back in place, it is actually uploaded, but won't boot anyway.
backup done by build.prop editor, and file pop and push from a linux machine (so no CRLF thing for sure).
attaching snapshot of logcat.txt
... *HELP*
thank you
the problem was in the file permissions. i had to remove write permissions to the group. (rw-r--r--)
You can fix permissions using adb

First of all DO NOT WIPE DATA / FACTORY RESET
This will remove adb access. Depending how far you can boot, do you get adb in recovery or normal. Can you use adb shell? If you can you can us adb shell chmod 644 /system/build.prop
EDIT:
Failing that try to install a zip. Sell my links for both current and older zips

[Fixed][Q] Can't exit Factory Mode

Hey guys, I had lost my IMEI today.
I was lucky to find an auto-backed up .tar.gz file of my EFS folder.
Restored that folder and my IMEI is back and calls and everything is working.
Problem? I'm stuck in a permanent factory mode.
There's no lock screen, power menu directly reboots phone and there's a frustrating yellow overlay of my phone information. These things just won't go away whatsoever. Tried ODIN and a lot of methods on the internet.
Tried these via terminal emulator:
Code:
rm /efs/FactoryApp/keystr
rm /efs/FactoryApp/factorymode
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
and tried to do these via root explorer apps also.
Please help I need to bring my phone back to life.
Edit: How I fixed it:
Not sure if step 1 is needed but this is how I did it. (I've used X-plore File Manager for all the file operations)
1.Change permission of every file and folder in /efs folder to 777. Reboot.
2.Delete the folder /efs/FactoryApp (NOT ENTIRE EFS FOLDER).
3.Wipe data/Factory Reset. (/efs/FactoryApp will get regenerated here)
4.Open /efs/FactoryApp/keystr file and change its contents to ON.
5.Open /efs/FactoryApp/factorymode file and change its contents to ON.
6. Reboot and your problem should be fixed now.
Are you doing it as root "su"?
What errors?

If you look at the 4th command in post 1, if you browse to and open that file, does it say "on" in it?

OK I tried to logcat it and these are just a few of the unhealthy statements(A lot were repetitions I guess).

I know almost all of these are pointing towards permission problems but I don't know why they're occurring. I've set all the permissions according to all the suggestions I could find here on xda.

Why don't you try setting perms to 777 and if it works start removing until it breaks.

What if I delete the /efs/FactoryApp folder and factory reset the device?
It should automatically get regenerated right? And will my IMEI stay after that? :-|

God it's finally gone. I think my whole FactoryApp folder was messed up.
I deleted it and wiped data from CWM. Rebooted and factory mode was still there. Opened both factorymode and keystr files and changed them from OFF to ON and rebooted again.
And I was greeted with the new phone setup on reboot
Thanks a ton all you fells. Problem fixed

OK I can confirm that you only need to delete the FactoryApp folder and do a factory reset for this to work. Dont worry about permissions. I couldnt get rid of the yellow writing even though my FactoryApp files said ON. Obviously corrupted because after deleting they said OFF, so changed to ON and fixed (6hours later!!!). All the abd stuff and terminal commands didnt work, only this solution. Dont worry the folder regenerates itself as he says so no risk.

i have swipe to unlock and no mobile data
if i set unlock to pattern it does stop and wait
if set to swipe to unlock it just goes right on past it on reboots
factory data mode is supposed to turn off isnt it?
what exactly is its function
well i just follow the directions with the echo commands and it actually made my phone worse
now i dont even see the swipe screen AND my power button has no menu to restart phone. when i hold power button in when phone is at ui it just shuts off now

[Q] Android won't boot after modifying system file

This is (nearly) my first post, so hi all !
Before I start with anything else: I searched a lot and found a lot of things, but I'm so newbie that I'm afraid to do anything because I don't quite understand what I'm about to do.
Oh, and I don't speak english natively so forgive me if I make any horrific mistakes :angel:
With all that said, let's begin with my problem...
I have a HUAWEI Y300-0100, and it comes with a funny feature: every time it can't connect to WIFI a popup message appears saying that if you switch to data plan charges may apply.
I am constantly switching between WIFI/no-WIFI zones so that message really bothered me, and I searched a way to disable it.
Presumably, the only way to do that is by modifying a system file called "build.prop". I already had my phone rooted so doing so wasn't very hard.
I used Jota+ to change a setting from "true" to "false" (ro.config.hw******), and saved the file in the root of the SD card. Then, with ES File Explorer, I renamed the "build.prop" in /system to "build.prop.bak" and copied there the "build.prop" I previously saved in the SD root.
All seemed to be fine, except that after rebooting my phone it could not get past the HUAWEI logo.
Android recovery mode seems to work, but I don't know how to use a lot of its options nor I want to do a Factory Reset if there's a better alternative.
Is there a way to modify system files before booting Android? I really would like to try to delete the "build.prop" file and rename the "build.prop.bak" back to "build.prop".
Does any of that make any sense? What do you recommend me to do?
Thank you very much for your help!
From within recovery open adb
adb pull /system/build.prop /some/location/on/PC
Now edit build.prop back to how it was
adb push build.prop /system
adb reboot

Thank you for your response!
I managed to restore the original build.prop, but the phone still doesn't boot.
..Maybe that wasn't the problem. I guess I'll factory reset...
--------------------------
After that it STILL doesn't boot. I have no idea what happened, I did nothing strange apart from editing that file :crying:
If you changed something in /system factory reset won't work
Try either fixing permissions in recovery or
adb chmod 644 /system/build.prop

URGENT: Build.prop deleting itself after each reboot

got an urgent and important question.. please urgent help required.!!!
I edited something in build.prop and restarted. phone goes blank after boot. Tried adb.. [build.prop not found] restored a backup of build.prop into system via adb but after reboot, same thing again and adb shows [build.prop not found again]..!! Can anyone help..?? Also didn't make nandroid backup..
Is there anyway to get the phone running again without losing any data..??
URGENT..!!
Are you either hitting fix permissions in recovery or using adb to chmod the build.prop after pushing it? If not this will happen.

TWRP edit mixer paths

I had some problems with an in call echo. So I tried to fix this by some changes in mixer_paths.xml. I copied the original file to my sd-card so I thought I have a backup. But after I made some changes the phone get stuck and won't reboot. I didn't expect this to happen!
I restarted my phone in TWRP and tried to copy the original file from the sd-card. But I don't know how I can do this. Does anyone have an idea?? Is it possible in terminal? Or should I connect the phone to my computer and try with ADB?
Hopefully there will be a solution and I don't have to reinstall everything!
Edit: In terminal and file manager (in TWRP), I can't find the folder "etc" in "system". There is only the folder "usr". Or should I look at another folder?

Could be just that you forgot to change permissions on mixer_path.xml....you could chmod it from twrp terminal.
chmod 644 /system/etc/mixer_path.xml
You could always restore your nandroid or dirty flash you rom.
