Unlock forgotten pattern

A few years ago, my bro has set a pattern lock for his old "G-Tide E66", then the phone was left abandoned. Now, I need this phone for some reason.

Info:

1- USB Debugging disabled.
2-Volume Up/Down corrupted.
3-Wifi / Mobile data are turned off.

Details:

- I get to the pattern screen.
-Andriod: Chocolate II
-Drop down menu, not working from the lock screen.
- No shareit to try open Wifi glitch.

Trials:

1-I tried looking for a pinhole to reset the phone ( Couldn't find where it is.)
2- Using Andriod Debug Bridge (ADB):
adb reboot recovery ( I got No command, Fixed it by holding the power button. then stuck in the recovery with corrupted volume down, I thought of triggering the key event from adb)

adb shell input keyevent 25 (25 = VOLUME_DOWN) ( I got this error: - exec '/system/bin/sh' failed: No such file or directory (2) nRet(-1) - Not sure about solution so I thought of another method.)

3-Using FastBoot:

adb reboot bootloader ( the phone reboots in recovery mode)
fastboot devices ( the device shows)
fastboot -w ( Loading for about 9 hours in "erasing 'user data'...." , I got this error: "FAILED TO read user data too many links" , I saw suggestions about rebooting the device, PC connecting to another socket ( In my case I have 5 , 2 of which are SS v3) triple failure.)

Other manual erases like:
fastboot erase cache (fail too).

4- Using Android Multi Tools v1.02b FAISAL JEE from SE-Thiland.
Reset Face/PIN Lock : rm failed for /data/system/password.key, Permission denied
Reset Face/Gesture Lock: rm failed for /data/system/gesture.key, Permission denied

Reset GMail:
rm failed for /data/data/com.android.providers.settings/databases/settings.db, Permission denied
rm failed for /data/data/com.android.providers.settings/databases/settings.db-shm, Permission denied
rm failed for /data/data/com.android.providers.settings/databases/settings.db-wal, Permission denied

Wipe Data/cache:
erasing 'cache' (forever.)

Wipe Data:

Wiping /data
Error opendir'ing /data 'Permission denied'
Done wiping /data

5- Looking for G-Tide reset code , I failed too ( Found None and I got Not Emergency number pop up).


6- Using the wisdom " When you are stuck , start to F***" , I started typing random ****, eventually failed too.

7- Calling 999 and trying to unlock fails.

8- Rooting using superSU

I tried this command not sure if correct:

adb install <PATH of SuperSU.apk>

"com.noshufou.android.su.apk"

I got success and not sure what to do next.

9- Recovery img:

fastboot flash recovery < RECVERY IMG>

I used this

cm-13.0-20160901-NIGHTLY-d851-recovery.img

Result:

sending 'recovery' (11648 KB)...
OKAY [ 0.373s]
writing 'recovery'...
FAILED (remote:
partition 'recovery' not support flash)
finished. total time: 0.392s


10- MirrorGO software.

11- Google Android Manager , apparently no internet so no luck too.

12- <I didn't try this> Installing a ROM

not really sure if that will work or screw everything, any ideas and how to install ?

is it ?

adb install <PATH of ROM.zip>


NOTE: I know the phone is dirt cheap , but I have to unlock it whatever the hell I do.

NOTE: If you think you can help through operating my PC through TeamViewer, give it a try.
I will connect the phone and you do the job.
NOTE: It seems like I have a masterpiece no info regarding E66, like the company created a single device.

Thanks in advance.
