What i did
okay so first i installed SGH-i957 cm10 rom and it did boot but i had to turn back to stock rom bc i had only 128mb for internal memory and it was partition on SDCARD1.
so i turned back into stock and i tried to fix the problem so i decided to clear cache and etc before i flash the rom. and also i saw that they said to use twrp recovery so i tried to find how to upload img file on my tablet then and i just installed rom manger and goo manger(i didnt install recovery from that tho)
but they didnt have option to install img file so i found out that if you use terminal with this code (su) (dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p6 bs=4096) you could install recovery so i used it (dd if=/sdcard/twrp214.img of=/dev/block/mmcblk0p6 bs=4096) and then i used titanium to backup all of my info and i restarted my tab and booom it was hardbricked TT (i also saw some cm10 apps when i was doing backup i guess stock didnt erase the files so that could be reason too)
Whats not working
Black screen (not even glowing)
Won't detect on the computer so no odin no adb
its not even on apx mode
all combinations of buttons doesnt work no recovery no download mode
so i tried turning on while tab is plugged on wall/pc but still doesnt work
also i tried taking out battery and tried it again but failed again (i cracked my screen on second try while opening my tab)
i tried charging it for 20hours but failed
i tried dying my battery and also failed again
but im still trying both method.
i found out that when i push power button i hear beep sound from top right corner and i hear tic tic sound while charging(i guess that beep sound is replacing booting vibration bc it takes 8sec to make that sound after i pushed the power button and to hear the sound i have to keep pushing the power button. and then after that beep it just keep making beep sound per sec. but both of this sound is super quiet so i have to put my ear at tablet.(combinations of buttons are same, tab only focused on turning on when i press other buttons with power button
Also after dying my battery, my tab wont make the beep sound without charger. but its still charges bc i could hear the beep sound without 8sec of delay when i plug charger while pressing power button .
so if i have no answer, im going to try this:
1.Unbrickable Mod (but i dont know how to find the ox stuff or mapping and im not sure if galaxy tab unbrickable mod will work)
2.Samsung (since my bro works at there and he is in developing team)
3.Jtag (im not sure if they provide Korean GT-8.9 but no choice if their isnt anyway) www . youtube.com/watch?v=BgL5vWRwh5k
