I recently wanted to change something in "build.prop". I did this action on Huawei Y530-U00. Plus, the phone is rooted too. I would not do anything without backing up files. Now I'm in recovery to solve this.
I got this backup file "build.prop.bak" on the computer via ADB, since then ADB commands can also be used via recovery. The problem is that I can no longer punch the file into the system.
This command will even crash the ADB: "adb root". This is just this command that just crashes. Others like "adb remount" work fine before I type "adb root". But there's also an error with the text "remount failed: Operation not permitted."
I've already checked these commands very well:
adb devices (yes, very good…)
adb pull /system/build.prop.bak (my backup file)
But this command gets on your nerves:
Command: adb push build.prop / system / (renamed from "build.prop.bak" to "build.prop")
Error message: adb: error: failed to copy 'build.prop' to '/system/build.prop': remote Read-only file system
I also checked one thing. This is the official build.prop file, which should also load officially. Then I entered the command "adb pull /system/build.prop C: \ Users \ Admin \ Desktop \". Works just fine. I open the file with Notepad ++, and see that everything was deleted there. No line left. Zero bytes.
I already know that if you enter any other file instead of /system/build.prop (for example: /system/dshndsfuvh.prop), an error message would show that this file does not exist. Did this restart really erase everything?
I would really wait for an answer. Please answer as soon as possible because I only have this phone to make calls (see my posts entitled "No services can be loaded from SIM card - what to do?" And "SIM card works on another phone but not on mine?").
Did you do a full backup via recovery? Then play that back and stop fumbling around there. If you don't have one, it was very stupid.
In that case, download the original firmware or the custom ROM and flash it.
And then stop fiddling with it again.
First of all, I can't make backups via recovery, because there's no tutorial at all to e.g. Install TWRP. That was my idea too, but I would rather need a scatter file to flash it.
Yes then… Flash the original firmware again.
It's best to go for Android help, or the XDA developpers if you are fluent in English.
