What you can do is titanium backup your apps, flash mg4 rooted, install suppersu and titanium, and restore apps.... Oh, you might have to flash modem if you want the mg4 baseband as well...
I understand. Just forget it. I'll wait til 4.3 drop in a little bit and go from there.
ok your making me feel bad... i work 14-16 hours most days, i look at the forums a couple time throughout the day while waiting on a customer, its tough for me to type every thing out in a way for someone that does not understand all the lingo and how the main programs work/operate... nothing against you, im just short on time so when i do try to help unfortunately my details are short too.... sorry
but here we go....
- get
Titanium Backup ★ root
- backup all your user apps using titanium backup (system too would not hurt)
- make a copy of your internal sdcard titanium backup folder onto you external sdcard
- Odin flash
ODIN Backup for --> SPH-L710_MG2 (read instructions)
- install
SuperSU
- install
Titanium Backup ★ root again
- using titanium backup restore
USER APPS and data ONLY (you can restore some system data like wifi or Bluetooth but do them individually and be careful)
===========================
to update baseband:
- download
[root] adbd Insecure read the description for a link to get it free
- from the app enable insecure adbd
- now you got to use adb.... or you can use
Terminal Emulator
-----
here is a simplified adb
----- unzip
----- connect your phone
----- click on cmd.exe
----- type: adb shell
----- type: su
- backup what you got type:
[HIGH]dd if=/dev/block/mmcblk0p1 of=/mnt/extSdCard/modem.bin[/HIGH]- from your sdcard move the new file "modem.bin" to a safe place on your computer...
- then download my
modem_MG2.7z
- Extract the
7-Zip file
- move the modem.bin to your sdcard
- then push it to you phone type:
[HIGH]dd if=/mnt/extSdCard/modem.bin of=/dev/block/mmcblk0p1[/HIGH]-reboot
goodluck
