How to ReadBack ROM using SP FlashTool, to cook CWM recovery & install SuperUser (get root) etc..
If your phone not rooted using the ROOT button.
Tips:
Make sure you installed all necessary drivers for you get started.DOWNLOAD ADB DRIVER
Here
Make sure USB DEBUGGING is enabled.
1. Make scatter by means of MTKDroidTools. Download (MTKDROIDTOOL) Here
Scatter is the text file with addresses of the blocks, necessary for the SP FlashTool program.
After creation of scatter don't close the main window of the program! Otherwise once again it is necessary to turn on phone.
2. In SP FlashTool choose this scatter and go on the Read Back tab.
3. Choose path and a ROM file name
Click on Add button. Double click of a mouse on the appeared line.
Choose a file name, the name has to begin with ROM_ as offers
FlashTool! Remember path and the name of ROM_ file.
4. Determine the ROM_ size
Type has to stand in HEX. In the field of Start Address it is necessary
to write down 0x000000. In the field of Length we copy from scatter the
address of the block following after RECOVERY or the address of other
block for fuller backup. For phones with type of the blocks EXT4 it is
the cache block address. The number in the Hex format has to begin with
0x
5 . Choose Read Page Only on yaffs2 type blocks phones
In FlashTool choose Read Page Only in the field of Read Method. If this
field isn't present, the window with this question can emerge, too we
choose Page Only. On phones with EXT4 blocks it doesn't get out (as a
rule).
6. Read Back ROM_
Click on Read Back button and connect the
switched-off
phone to PC. Here the options depending on a concrete phone are
possible. Maybe it is necessary to press at the same time with connect
of a cable the camera or volume buttons. Experiment and study work with
FlashTool in threads with similar phones! On some MT6573 models, for
example on B63, it can't be executed with any combinations and only
testpoint need!
7. Prepare files for FlashTool and make CWM
If everything passed without errorss, we open the MTK Droid Root &
Tools window which we left on 1th step. If for some reason the window
isn't present, it is necessary to turn on phone and to connect it to the
program. Click on
To process file ROM_ from FlashTool button and
choose the ROM_* file saved on the 6th step. At successful unpacking
rom it will be offered to choose CWM from similar phone. Chosen CWM it
is checked on compliance to the connected phone and if ok, the CWM is
created.
Starting with v2.4.0 CWM it is made automatically and the file from similar phone shouldn't be looked for any more!
Аttention! Yaffs2 type blocks from this backup can't be Downloaded to
phone, they aren't correct! Use backup on 9th step if phone have yaffs2
type blocks!
8. Download new CWM to the phone
Start FlashTool, choose scatter in the folder created on the 7th step.
Remove marks from all blocks! Click on RECOVERY and we choose the file
CWM in the same folder which was created on the 7th step. Click Download
and connect a cable to PC (phone has to be switched off) and expect
the end of process.
DANGEROUS! On this step the CWM
recovery block has to be marked only! Also it is necessary to use only
the Download button and not to use at all the Firmware Upgrade button!
9. Make backup, install SuperUser etc
Load phone in CWM mode, connect to MTK Droid Root & Tools, go on the tab
root, backup, recovery and, pressing on this tab the necessary buttons, we do:
- backup! ! ! (if in phone there is yaffs2 type blocks, do here surely, they received with readBack on 7th step aren't correct)
- install superuser (often mean "get root" under it)
- and other if need
Never needlessly Download preloader and DSP_BL
blocks! It is always dangerous! On some models of phones (for example
Alcatel) you will have a brick even if you download these blocks read
from phone which you own! Always remove from them marks in SPFT!
