  1. Ok
    It is working on kitkat 4.4.2 (Lenovo s820 4g). Two thinks: 1. After using the Mateos app, I had to reboot in recovery mode manually. 2. I had to format my sd card. This wasn’t a problem, I took all important info out from the sd card to my pc, and back again. ALL is working, so thank you again Andy for this guide.

  2. Hello, I have a problem here because I did the wipe date on stock recovery… I didn't have data on SD Card and didn't want to backup and restore so I didn't do it… I got rebooted on stock recovery from the meteos software… Please advice…

    1. Hi,
      This cannot guide cannot done with stock recovery and it will 9nly brick your device, need custom recovery format function ext4. Are your phone still can completely boot? If not just reflash your device, because i think the partition is already brick because cannot format.

    1. hello,
      sorry for what you got. Stuck on lenovo logo mean you got bootloop, have you format /data from CWM, if you saying that you cannot go to CWM then please try again power button + Volume Up + Volume Down, it need to format /data from cwm before booting

  3. Hi,
    I have Lenovo S820 CN 4GB.
    I am using TWRP and when I get to step 5 (Wipe Data / Factory Reset) i get this error – E: unable to mount '/emmc'. If I try to Restore Data I get the same error. When I reboot the phone can not start and I need to flash it to get it going again. I think this error is occurring because I am using a custom recovery.
    So can I ROOT the device with the factory recovery mode or with out the recovery mod at all and then do thi guide with the factory recovery mode?
    I dont care if I lose my data, so I can skip the backup and restore steps.
    One more thing – is this repartitioning permanent? When I flash another ROM the next time do I have to do that again?

    1. Hi,
      No you cannot root using standard recovery unless you root your devixe using one click method, framaroot, vroot or root genius and other. If you don't need to backup and restore you can skip it. What you use 2GB or 2.5GB for the partition?
      If you are using 2.5GB try using 2.0GB and if still error try using another mode, thus cyange will keep unless you format when installing the new rom, if you just update this change will keep in your device

  4. So there's only 1 person which has been succeeded in Re-Partition Internal Memory on Lenovo S820 Android Kitkat 4.4.2
    I'm afraid to do it, cause i don't want a brick. Anyway will try it soon! By the way Andy could you please confirm that it'd works like a charm in Kitkat version?

  5. Hi Andy
    Is there any way to move or install apps to internal USB storage? Because I have 1.29GB Available for USB storage. And in My Internal Storage has only 149MB left 🙁 that sucks… Please reply how to do it or make a nice tutorial

    1. To install on internal storage is ROM capability and for kitkat i think there is some applications that on the internal usb storage and the other is on internal memory but the applications size is small the big one is the data file and it always install on internal memory, when use jelly bean or ginger bread you can use link2sd but on kitkat i don't know because i am not lack of memory

    1. Hi,
      To use link2sd you must have 2 partition on your sdcard. Are you have it, but i think you not on that step. Link2sd package invalid i think it the package need to redownload, but i don't know is link2sd work on kitkat since kitkat not allow 3rd party wriite to sd card

  6. Hi bro,
