Mijue T200 MTK 6735 - how to backup Stock rom from phone
(14-02-2016, 12:37 PM)swimmer3000 Dear,
I have been looking around how to make a backup of my rom.
The phone is a Mijue T200 with the MTK 6735 quadcore processor working at 1.3Ghz.
The reason is simple. One way or another these 'tools' at Mijue have implemented the idea of splitting up a 16GB interal SD rom into 2 partitions - with only a 2GB partition to install apps on (and 10GB of user data). Can you believe it? This makes the phone almost completely useless. You can install a few apps, and that is it.
I have found a potential solution to resize the partitions on xda
http://forum.xda-developers.com/general/...l-t3180978
however this is only possible when a custom recovery is installed.
This leaves me with a problem. How to install a custom recovery, if there is one.
The phone cannot be rooted with any of the available tools. I have tried!
I do NOT ave available a stock rom. (I think Mijue is bankrupt or something, because nowhere there is information to be found of the company anywhere). THEREFORE I NEED TO DO A READBACK OF THE STOCK ROM FIRST.
My plan of attack.
1) Use SP flash tool - to read back the rom BUT problem - I do not have a scatter file.
2) I have found scatter files from another mt 6735 phone, but they are not exactly the same - thus
3) Using Engineer mode, I have been able to read back information from emmc memory of the phone and I think I can change the few things that need to be changed.
If successful, this allows me to read back the entire rom from the phone and store it.
Question:
1) how to proceed from there?
2) Do I need to read back entire rom, or should I read back any single partition?
3) If I read back any single partition, how to name them?
4) How to create a custom recovery (TWRP/CWM) out of this?
All help is gratefully acknowledged!
Sven.

(14-02-2016, 03:19 PM)swimmer3000 So, I managed to download the 'd' version of MTK Droid Tools 2.5.3 and.....
NO GO. It is not possible to create a scatter file. The button is 'greyed' out.

(14-02-2016, 04:13 PM)swimmer3000 That is it. This is how far I am.
Apparently I can readback some files from the phone rom, but I have to way of checking if they are the correct ones.
Any updates on this are highly appreciated.
Thanks,
Sven.

Using the method @ https://www.hovatek.com/forum/thread-526.html, readback only recovery.img
No need to create a scatter file, you already have one.
Start = Linear start address
Length = Size
(14-02-2016, 11:17 PM)swimmer3000 Dear Hovatek, thank you for the quick reply.
I will do that tomorrow.
I suppose that the recovery.img is enough to make a custom recovery?
How to create a full backup of the rom? Probably after I installed a custom recovery I suppose?
After I have the recovery.img, what then? Should I post it?

(15-02-2016, 11:22 AM)hovatek You can't process ROM_0 using MTK Droid tools since it doesn't support your phone model so you'll need to readback one partition at a time.
Send the :
Phone model
Recovery.img
