First your report :
first : there is no initlogo.rle anywhere, and when I checked the file "init" (which is binary file) I found a line
Its that .... Most of the chinese tablets do not allow changing bootanimation ..
If it allows ... Its said to be Unseen
"init" file ... You can find it while Searching deeply..
If u find its not available .... Then its said to be waste
Second the report :
After I have installed adb in linux and I made some changes to the tablet, after rebooting all changes not being saved
just like I didn't do anything
Check whether the adb Works properly ... most of the adb's do Such things
After you reboot the tablet " Everything becomes normal as if it was " Before changing " ..... This problem is strange as you can refer it by asking some Mod's r developers ....
This is my guide to you .....
Hit thanks if i have helped you
