Have a boot loop problem after editing build.prop file - General Questions and Answers

I tried to install system UI tuner on rooted lenovo A 5000 ,it was not compatible with my android version.
Any way i tried to edit build.prop using build prop editor app on play store the modification gone successfully(I changed android number from 5.0.2 to 7.0-and SDK version from 21 to 29),then i rebooted my phone for the modification to take effect,after the phone booted most apps stopped working-including the build prop editor app- i tried to reverse my actions by changing numbers to the previous state by using ES file explorer in the root explorer but the text editor also stopped working .then the last try to fix my phone was by using ADB on linux i used the terminal to pull system/build.prop to my PC then editing it by the text editor manually ,then i copied the file to my phone then i opened ES again and moved the file to system/build.prop and it deleted the file and replaced it then i rebooted the phone then it did not stop the boot animation then i knew that my phone had a bootloop
please help me find a solution,How i can reverse everything or shall i install a custom rom or anyone has any other idea.
NOTE : All lines inside the file were like that :"something = x" except one line which was "something = " only .

[Q] Issue editing build.prop

I recently rooted my Inspire and loaded CM7.2 RC1 and I was just trying to increase my download speeds by editing the build.prop file. I'm using explorer v1.1 to get to the system folder and then editing the build.prop file using the text editor. When in explorer it says r/w and I can actually edit the file and save it but it never seems to actually save the changes even though it says it did. I tried using mount/system(rw/ro) to ensure that it was actually mounted but I am getting the same result. Any suggestions would be appreciated!
ES file explorer
Hi, I use the es file explorer, when you open it up hit "menu" scroll to bottom and make sure both root settings boxes are checked, then restart app. You should be good to go.
I recommend ROM Toolbox. It has a root file explorer and many other tools which come in handy on a rooted phone.

System "semi" Writable?

I recently Wiped my Phone completely and decided to Re-Flash Viper 1.2.1.
I noticed a problem prior to re-installing but thought nothing of if since it wasn't crucial at the time.
In Root explorer, I am able to delete [i normally delete boot animations] system files but not add where I need to add. Example, I wanted to add a ringtone to my system/media/ringtones folder. I normally [for the last six years] could just copy and paste such files using a root file manager.
However, when I any these files to for example /system/customize/resource/ it doesnt add it. BUT IT DOES rename the file and save it under a dif folder.
Example. Tried copying-copy to-moving to "androidtwirp.mp3" from sdcard to /system/media/notifications and a message pops up saying"notificationsandroidtwirp.mp3 successfully copied-moved to" and it saves notificationsandroidtwirp.mp3 to /system/media/ and it stays there. retrying from that location only results in "notificationsnotificationsandroidtwirp.mp3".
So not only does it rename the file but it saves it in the wrong location. I am at a loss for word. I tried the basics to tryand fix this but i cant seem to hit it on the head.
Thanks!
Edit: Not updating Super SU app, file explorer seems to have worked. Will attempt to duplicate problem to see what actually caused.it.
FOUND IT!
Updating my ES File explorer broke my system writing ability. DO NOT UPDATE is because when you do...
Any file you move, copy/paste to the system will not work properly.
This first happened when I tried to copy and paste a boot animation after I updated ES root explorer. It would rename whatever file i was trying to paste/move/copy over and save it under a sub folder.
example.
copying a ringtone [i.e. androidtwirp.mp3] from SDCard to System folder, the path is /system/media/audio/ringtones/ and it would rename it "ringtonesandroidtwirp.mp3" and save it under /system/media/audio/.
So basically not only was it renamed [which i didnt want it to be] but it would save it to the folder before the actual folder i needed it to be in, plus it would corrupt the file deeming it useless.
moving "ringtonesandroidtwirp.mp3" into the correct folder would only result in "ringtonesringtonesandroidtwirp.mp3"
this happened across the board with all files being moved around
The ES File Explorer version 1.2.1 comes with works flawlessly so don't update it.
I uninstalled ES [also any folders in SDcard related to it] and downloaded JRummy's root explorer and everything is back to normal except i have to reboot the phone to see files [like ringtones and notifications] that i added to the system.
I think it has something to do with our devices having an unlocked bootloaader, but still S-ON. There's S-OFF in the Dev section now if you really need to write to the system folder a lot.
I came from the Vibrant so I know what you're going through
Yeah, im on a low hboot so s-off might not be in my plans since I can practically flash what I want but it was ES file explorer, when I updated the apk the root permissions broke when writting to the system. I emailed the dev and they said they'd have it fixed on the next update.

[Q] Build.prop reverts when I reboot

I've been trying to modify my build.prop to enable carrier billing on my T-mobile One S with Zen Rom 1.05, but every time I reboot it reverts back to the one that came stock with the rom. I'm mounting R/W and I've copied the file onto my SD card after editing it to be sure it was actually saving. The copied file shows all of the changes, so I'm sure it is, but as soon as I reboot, the one in \system reverts. I've tried build.prop editors from the market, and editing it from root explorer's text editor, and it's all the same. Any ideas?
Thanks!

I need help PLEASE!

Hello guys. Maybe you can help me. I tried this:
http://forum.xda-developers.com/att-...using-t3088431
As the step 6 says, there wasn't such a line so I created it. As some of the first comments stated, when I restarted, I got stuck in the AT&T logo screen. After a few attempts of restarting it wont do anything else. so I tought that a master reset would fix it. I was able to reset it however, it asks me to set up the phone (common stuff, set language, pick wifi, set google account etc) but when those steps are done it takes me back to language screen, and then repeats all over again
Im stuck in that infinite loop. One thing is that at certain screen I'm able to access the settings, and we managed to put the phone in "easy mode" which allows me to use the phone, however, I cant go back to normal mode because it will get stuck in that same infinite loop. This is what I have:
LG-H950
Android 5.1.1
Kernel: 3.10.49
V: H95011x
I need HELP!!
Thanks
First of all, the link doesn't work. http://forum.xda-developers.com/att-g2/help/enable-tethering-att-lollipop-using-t3088431
So you said that your phone is stuck in a boot loop. I think that you have to reflash the original kdz.

I just checked the link and is working. If you still cant see it, this is what it says:
Things needed for this
Root
ES File Explorer File Manager
SQLite Editor
Steps:
Open ES File Explorer and from Fast Access Bar, From "Tools" Turn "Root Explorer" on
Go to this folder "\data\data\com.android.prodivers.settings\databas e" and copy "settings.db" file to "\SDCARD\Downlad" path
Open SQLite Editor and go to "FILES" tab from the top and open "settings.db" file from "\SDCARD\Downlad" path
Hit "system"
Search for the term "tether" in all fields
Change the value of "tether_entitlement_check_state" to 0 (If the entry is not there, create such)
Copy and replace original "settings.db" file from "\data\data\com.android.prodivers.settings\databas e" with our edited "settings.db" file from "\SDCARD\Downlad" using ES File Explorer
Restart the device immediately
Enjoy your ability to set up a mobile hotspot!
And, sorry for my ignorance but, how do I reflash the original kdz?
Can someone help me?
Use LGUP, select refurbish, choose the tot file, press start.

[Tutorials] How to enable Wireless Display/screencast/miracast in Lenovo K8 Note/Plus

As many have asked about this, I am writing this tutorial. It is a simple trick. But for that you need to root your device or atleast have TWRP recovery installed. I am going to give two methods, if first simpler method does not work (it does not for me), then go to second.
If you know how to edit build.prop, then just do this, add 3 lines given below:
Code:
ro.hdmi.enable=true
ro.hdmi.mirror.enable=true
persist.debug.wfd.enable=1
If you have any issues see method 2.
If you don't know what is build.prop don't worry, I will say steps.
Method 1
This method involves directly editing the build.prop using es file explorer.
Download ES File Explorer from play store
Enable "Root Explorer" in ES and give root permission. Click the "Root Explorer" and then "mount R/W" and then mount system "RW".
Now click "device" in ES and then go to "system" folder, you will find a file named "build.prop".
Open that file in ES note editor which is already installed by ES. Click pencil icon to edit.
Scroll to last and then add the 3 lines I mentioned in this thread and save the file.
Now simply exit the app and restart your device.
Now open settings then display then cast, click 3 dots on top right and enable Wireless Display.
Method 2
As I seen in many phone, the build.prop file restores to original during reboot, which is causing the method 1 to not work, so use this method to to do the edit from TWRP file manager. This method worked perfectly in my phone. See steps below:
Follow till 3rd step in method 1 and just copy the file "build.prop" to Internal storage.
Now edit the copied file in internal storage as mentioned in 4th and 5th step of method 1 by adding 3 lines.
Reboot to twrp recovery, you may use the app named Quick Reboot [ROOT] from play store.
Now in TWRP go to Advanced and then choose file manager.
Scroll down and go to the folder "sdcard" that is your internal storage. Now click the build.prop file there and choose copy.
Now go to system folder and copy/paste the file.
Reboot to android. Now do 7th step in method 1.
Screen cast can be enabled by magisk too. See this https://www.xda-developers.com/magi...iracast-and-tethering-and-disable-adb-notify/
For me that did not work so I myself made magisk module zip. Please check the attachment. Just download and install from magisk or twrp. It is tested to work in magisk 15.0+
Note this method may work in other phones too, but I don't have those phones with me. I have received many messages asking how to do this, so I am making this to help all of them.
Thanks to Dhruv_Agarwal in Telegram for giving me the 3 lines of code.
