I asked in another forum but they couldn't help me.
They said development for RK3188 stops with KK running on a 3.0.36+ kernel.
I have Lollipop
ro.build.fingerprint=FiiO/X7/rk3188:5.1.1/LMY48Y/FiiO02172023:user/release-keys
Unfortunately.
Boot is locked:
ro.allow.mock.location=0
ro.debuggable=0
Selinux is present.

Kernel is present in kernel partition for 3.16_Beta, however bigger then 8 MB:
3.0.101+ #561 preempt 17 Feb 2017
Also it seems the tab uses eMMC:

The update.img file is inside this archive, which contains the kernel, boot, fw, etc. FW 3.1.6_Beta.Zip
I used This to extract it. Downloaded RK3066_IMG_Mod_Tool.zip and renamed the update.img file "wendal.img" and dragged it inside the RK3066_IMG_Mod_Tool folder, then simply pressed "Runme" and then 1 to unpack, but you most likely already know all of this.
Here are the extracted files just in case MEGA
Let me also link an older FW that contains a RK3188Loader(L)_V2.15.bin and 3.0.36+ kernel inside along with other boot files that are also compatible with the newest FW, which are all Here
I tried using the CWM/TWRP generic which I got here to flash, but TWRP does not boot (maybe due to the 800x480 res), CWM does but it gives me these errors;
"E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
E: Can't open /dev/block/platform/ff0f0000.rksdmmc" errors and more.
None of them work yet sadly.
I can only root as of now, so no Viper4Android, no TWRP or CWM, or Xposed Installer. Would greatly appreciate some help.
