[Android General] hackwerk:
Hello

Hey guys (and gals?)! Great to see there is a Lenovo Tab 2 A10-70F thread! At first didnt find it, but as you see I did.

Today I received (in The Netherlands / NL) a Lenovo TAB 2 A10-70F (16GBE-SE (ZA000016SE)) which is manufactured at 2015-12-09.

It came with Android 5.0.1 preinstalled (the A10-70F_S000120_150907_ROW version). This means I can update (OTA) to 1 newer version I guess (you posted the S000121)?

I have a lot of experience with MTK/MediaTek, as I started the big thread about my former Acer E380 with MTK.

I love playing (backups, rooting, tweaking etc) and I will do so with this tablet too, but I have some questions first,

because I want to make a scatter file AND full backup without rooting or even connecting WLAN or updating etc first

(on my Windows machine):

1) My MTK Droid Tools (2.5.3) shows all info of the Lenovo nicely including the (shifted?) block info (see image), but I can not press the Create Scatter File button (is greyed out). I see the error "--- ERROR : --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!!" so how do I get a good scatter?!

2) I tried "cat /proc/mtd" (empty) and "cat /proc/emmc". This second command gives good info so put it to firmware.info and loaded it to MTK Rom Studio. This shows a wrong list, and makes an even shorter/more wrong scatter file! When I manually add the preloader block (0 to 4000) it is way better, but the end is still totally wrong. Why?!

3) My scatter files and /proc/emmc is TOTALLY different (addresses) than the ones in this/your thread (for TWRP, Android 4 AND 5). Why?! Will they change when updated to latest OTA or?!

Guess my main question is how to backup up the whole machine and have seperate images and a correct scatter file for THIS state (no root, no sd, no updates etc)?

Or shall I first update anyways, and the do the root recovery method?

Here are my files:

cat /proc/emmc (seems good, but no preloader?!)
