I recommend to use tool from this thread to fix such market problems: https://xiaomi.eu/community/threads/universal-tool-for-managing-mipad-2.36891/ This is another option how to fix 963 error if you already have unlocked, installed TWRP and so on and still nothing working. If you are going to do something like that, that means that you are familiar with driver installations and command line. 1. Download this archive: https://pucina.dedyn.io:8181/data/public/74a019 2. Extract archive downloaded above to somewhere (let's say c:\adb, let's call it N1) 3. Download this image: https://pucina.dedyn.io:8181/data/public/4bd3d9 4. Put downloaded image to N1 folder 5. Connect pad to PC 6. In Windows explorer, when adb (N1) folder opened press Shift and right mouse button and select "Open command window here". 6. Boot into fastboot with buttons combination or write in black window "adb reboot bootloader" And now you can try 2 ways: 7.1 When you tab in fastboot mode write in black window "fastboot format data" or 7.2 When you tab in fastboot mode write in black window "fastboot flash data userdata.img" Reboot your tab. Note, all your user data will be lost and you will need to setup your tab once again. Then flash ROM version you would like to stay with for now. When you are on ROM version you would like to stay, I suggest to do Factory reset and re-setup. FLASH WIPING DALVIK, CACHE and DATA. DO NOT TOUCH SYSTEM NEITHER BEFORE NOR AFTER FLASH!!!!! If you will stay with latest version from xiaomi.eu, you need to install GAPPS separately. Use installer from OpenGapps for x86_64 system. Link to original post: http://4pda.ru/forum/index.php?showtopic=713227&view=findpost&p=49824875 P.S. Small explanation about source of error 963. During unlocking your PAD, system informing that you will loose your data, but system not wiping data, but killing data partition. So if after unlock, you will flash TWRP and will go there inside and will check partition information, you will see partition type of data="auto". If you will leave as is and will continue to boot into system, data partition will be marked (IMHO android system not really formatting it during boot) as ext3, but this is not enough for Gapps. And you getting error 963. So if you will change format from "auto" to ext4 from TWRP or by flashing userdata.img or by using "fastboot format data" you will never get error 963. From my perspective "fastboot format data" command should be added to unlock script. Also ROM makers (probably) can add check of data partition format and re-format if needed.
