Menual rooting for opi plus android 4.4.2

garyang

Hi~~
I've finally found rooting method.
You have to connect opi plus to PC via uart.
You need usb-ttl device or other serial device.
Connection baud is 115200/8/1/none/none.
Open terminal(I use putty).
Power on opiplus. you can see the booting message.
extract su.zip and copy all file to /sdcad/su on opi. (you should make dir /sdcard/su on opi before copy it.)
here is command
--------------------------------------------------------------------------

su

mount -o rw,remount /dev/block/by-name/system /system

cp /sdcard/su/su /system/xbin
cp /sdcard/su/daemonsu /system/xbin
cp /sdcard/su/install-superuser.sh /system/bin
cp /sdcard/su/Superuser.apk /system/app
cp /sdcard/su/.installed_su_daemon /system/etc
mkdir /system/bin/.ext
cp /sdcard/su/su /system/bin/.ext/.su
chown root:shell /system/xbin/daemonsu
chown root:shell /system/bin/.ext
chown root:shell /system/bin/install-superuser.sh
chown root:shell /system/bin/.ext/.su
chmod 755 /system/xbin/daemonsu
chmod 6755 /system/xbin/su
chmod 755 /system/bin/.ext
chmod 755 /system/bin/install-superuser.sh
chmod 755 /system/bin/.ext/.su

reboot

Make sure your opi same as directory map before reboot.

Enjoy rooted system~~~~~~

With root, I can change the resolution and install play store?

Not work with OPI2

Hi there!

What is the result of rooting? As I understand, the aim is to install "su" to xbin and give it 6755 access rights. And after that you can test "su" in terminal emulator, right?

I don't want to change working eMMC image (and haven't tried UART yet), so I played with TF image. I can change files on TF card using linux box, or using imgRePacker. I tried different binaries of su and none of them working: file is present, filesize is correct and access rights -rwsr-sr-x but return code is 1 and no hash symbol after execution in android terminal emulator. Superuser application complains on su binary, and every Root Checker says system is not rooted ("su is present but Superuser.apk is not installed correctly").

What is the difference between "su" on eMMC and "su" on TF?

There is no difference between "su" on eMMC and "su" on TF, but it is not so somple as to copy su binary.
There are some instructions and scripts about how to install root support on this forum, search.

Instructions are useless if something goes wrong.
I need information like what executes install-superuser.sh and when. Or information why copy of "su" must be in hidden ".ext" directory.

Hi, dear friends!
I found how to root OPI2.
After all task from head-top, you need rebot your device. After restart in TTL do:

mount -o rw,remount /dev/block/by-name/system /system
/system/xbin/daemonsu --auto-daemon

In graphical start SuperSU and make update su-file.

After this manipulation, I have root on my OPI2 mini


p.s. I change SuperSU.apk to last version (2.49) form http://4pda.ru/forum/index.php?showtopic=318487
