ROOT

Files and programs necessary for receiving ROOT:
in archive the TPSparkyRoot program with Root Explorer.

Instruction:
1) turn off phone
2) hold vol+, menu and press on button
3) screen should be blank - download mode
4) insert usb cable to phone.
5) run TPSparkyRoot.bat
5.1)Phone will reboot the first time. After a full load of the smartphone we press «ENTER» a TPSparkyRoot.bat program window.
5.2)Phone will reboot in the second time. After a full load of the smartphone we press «ENTER» in a TPSparkyRoot.bat program window.
5.3)Phone will reboot in the third second time. After a full load the smartphone will be root (but I recommend to overload once again phone manually).
5.4)After phone loading in the list of appendices there should be 2 appendices (SuperUser and Root Explorer). It means that, ROOT is received.
6) rooted!!

For my way the basic (and most likely in it your mistake) are the correctly established firewood on 6575 and the included mode of debugging on USB. If firewood stands "exactly" that in a task manager should be here as on a screen.

The guide to an insertion by means of SP Flash Tool for all MT6575/77 of devices


It is required to us:
1). SP Flash Tool program. SP_Flash_Tool_v3.1224.01.
2). MT6575 USB VCOM drivers.
3). A factory insertion for your smartphone.
4). CheckSum_Generate program.
5). (unessentially) Modified recovery.img for your smartphone.
Download already ready Modified Recovery with all necessary files:
modified recovery for i9300MT6575.zip

Instruction:
0). We unpack archives SP Flash Tool, MT6575 USB VCOM, CheckSum_Generate and archive with an insertion. We copy the CheckSum_Generate program in the folder with an insertion and we start it (in the folder the file of checksums Checksum.ini will be generated). If you have modified recovery, the recovery.img file in the folder with an insertion is replaced with your modified.
1). We switch off the smartphone. The cable isn't connected to the computer.
2). We take out and insert back the battery.
3). (pass, if drivers are already established) we Connect phone to the computer a cable. The operating system will find the new device — specify to system the folder with the MT6575 USB VCOM driver (for the version of OS).
4). (pass, if drivers are already established) we Disconnect a cable from the computer.
5). We start the SP Flash Tool program.
6). We press the Scatter-loading button and we choose the file MT6575_Android_scatter_emmc.txt or MT6577_Android_scatter_emmc.txt (it lies in the folder with an insertion).

7). We press the Download button.
8). We connect phone to the computer a cable. The program should see and begin it an insertion. If phone isn't found, disconnect it from computers, pull out and insert the battery and anew connect to the computer.
9). After the termination of an insertion we disconnect phone.

10). It is ready!!!!!

The guide to installation of modified recovery (separately from a full insertion) for all MT6575/77 of devices


Download already ready Modified Recovery with all necessary files:
modified recovery for i9300MT6575.zip

It is possible to establish modified recovery together with installation of an insertion of phone.

But, if the insertion at you is already established, the system is already adjusted under you, and anew to stitch an insertion it would not be desirable, it is possible to establish modified recovery, without mentioning system and other parts of the device.

For this purpose use "The guide to an insertion by means of SP Flash Tool for all MT6575/77 of devices". Only before an insertion (Download button pressing) remove ticks opposite to all points, except RECOVERY. The prevention of the SP Flash Tool program we answer Yes.

No, I have no such problem, it seems everything well works!
At me only GPS badly catches satellites and the program of navigation doesn't work, i.e. satellites aren't found by GPS...

Thanks for creating this thread. Hopefully theres someone with dev knowledge or who can read chinese blog will be able to find other info on this phone.

I just bought this phone a couple of days ago and able to get root access using this method : http://forum.xda-developers.com/show....php?t=1886460

My 1st problem that i found is that the wifi signal is very weak and occasionally drop. Even Im next to my wireless router. I've checked with Wifi Booster apps, this phone indicates my wfi router signal strength is -200 wheres my other phone indicates -80 (lower is better).

And i cant really understand your instruction on how to flash custom recovery for this. What is factory insertion?

If you are having trouble with SP Flash Tool, search for a video tutorial on how to use it, that worked for me! [COLOR="Silver"]
