Making a TCL Read & Write

General
1

I want to delete the browser permanently. I have the commands to do it (su mount -o rw,remount / rm -r /system/app/Chromium) but I believe it’s not working because it’s read only.

I tried adb shell su /vendor/bin/write_protect 0 reboot a few times and it didn’t work.

Credits to @FliphoneBochur for those commands.

Those commands probably require root

I am rooted.

Insert a && between commands. Also, go to /proc/mounts and open as TXT, and check what can be mounted… sometimes you gotta go

mount -o remount,rw /
mount -o remount,rw /system
mount -o remount,rw /vendor
mount -o remount,rw /product
mount -o remount,rw /system_ext

And so on…

You need to disable write protect first with the command adb shell su -c /vendor/bin/write_protect 0 and then reboot i usually remove it with fx in system>app>chromium delete the whole chromium folder

That doesn’t help for tcl

I did that already but it did not work, I am still read only.

Are you getting an read only error?
My personal experience was that it would work to delete but it would return after a few minutes or a reboot. I had tried on close to 10 phones and was never able to delete it. I saw on the to do list on @netroscott 's page (about a year ago) was to figure out why some phones won’t remount.

Try it in recovery. I remember having this issue once, if I recall correctly using neutrons recovery image it worked

12

Where do I find his recovery?

13

Didn’t work for me in recovery.

14

Whats the step’s? fastboot flash recovery... and then?

15

Then use adb through recovery like before

16

So after flashing it I should put in adb shell su /vendor/bin/write_protect 0 without rebooting first?

17

This is what I got when doing it in neutrons recovery:
C:\Users\\OneDrive\Desktop\ADB Latest>adb shell
$ su
# /vendor/bin/write_protect 0
/system/bin/sh: /vendor/bin/write_protect: inaccessible or not found

When I rebooted I still had my browser.

18

it should be set to 0 already anyway.

19

Is there any reason I should flash the stock recovery back on?

Is there any way to delete the browser permanently without read write permission? (Maybe a third party app…)
