GIT STASH

Use git stash when you want to record the current state of the working directory and the index, but want to go back to a clean working directory. The command saves your local modifications away and reverts the working directory to match the HEAD commit.

The modifications stashed away by this command can be listed with git stash list, inspected with git stash show, and restored (potentially on top of a different commit) with git stash apply. Calling git stash without any arguments is equivalent to git stash save. A stash is by default listed as "WIP on branchname …", but you can give a more descriptive message on the command line when you create one.

XOOM DATA AND BLOCK MANIPULATION

FLASH IMAGES
./fastboot flash boot boot.img
./fastboot flash system system.img
./fastboot flash recovery recovery.img
./fastboot flash userdata userdata.img
./fastboot erase cacheB

MOUNT FROM SHELL

LARGE BLOCK ON DEALING WITH SBF:  NEED TO SORT

convert image for splash image

#!/bin/bash

sudo apt-get install imagemagick

convert -size 1280x800 xc:black logo.bmp
dd of=tmp.bmp if=logo.bmp bs=1 count=54
dd of=tmp.bmp if=logo.img bs=1 count=3072000 conv=notrunc oflag=append
convert -flip tmp.bmp logo.bmp
rm tmp.bmp


chmod +x sbf_flash
./sbf_flash filename.sbf
The output looks something like this -
SBF FLASH 0.01 (mbm)

I found a guide for the E2, the E6 and A1200 are identical except for the different code groups, which was posted on your forum I b
elieve. Well heres the guide(for the E2 but its applicable to the E6)

Use SBFTool for parsing:

1. The cg34.smg is picture, ringtone, power up off image, and so on icons
2. The cg37.smg is secure setup ( notice that has 0x1000's FF head file, delete it first when modding). It's important because the flexbit in it
3. The cg39.smg is boot logo(not the poweron image,but before it)
4. The cg41.smg is usr/language , so we change fonts here
5. The cg42.smg /usr/setup , some setup config files
6. The cg43.smg / , main file system, the bin, lib, the SYSqtapp ( 0x1000 FF head file)
7. Beside cg39.smg, the other cg34 cg37 cg41 cg42 cg43 are cramfs file systems, you can mount -o -loop the smg in linux(root)

# tar zcvf xxx.tar.gz mountedsmgfolder
# tar zxvf xxx.tar.gz -C targeteditfolder

so you can mod the files in target edit folder then

# mkfs.cramfs targeteditfolder/xxx cg##.smg

so you made a new cg##.smg yourself
You can overwrite the smg content in sbf, be carefull the 0X1000 ff head file, and the origin size of smg , plast FF to your new smg to make the size the same
Make the sbf this way will failed when flash finished ( but it works, it really flashed into your phone), because there're checksums in the position 0x300 ~ , 2 block the end of each line
Use checksum.exe to see the checksums( if you got the value EC FA, it should write as FA EC, it must be the opsite of checksum.exe value)
Overwite the checksums, flash will be perfectly finished"

sudo apt-get install cramfsprogs fusecram
mkdir /tmp/image
