update:

Flashed with no problems. I elected to keep all my data during the flash which made it unbearably slow after the process was complete. I let it continue to poop its diaper for a bit and things have gone back to normal. I think I accidentally left the wipe cache button clicked. oops. Overall it's pretty nice!

if you are rooted and flash 4.0.4, u will end up soft brick your device after the first time you turn off the phone on ICS. I have tested it. If you want ICS, make sure you flash back to stock first. this will prevent this happen.

HI，I‘m夏一一（Alan）

Thank you for share it.
HI，I‘m夏一一（Alan).
Remember!!!
DO NOT ROOT USING 2.3.7's way.
It will let you 28i shut down forever.
If you do it, unload and loading battery then flash a new FTF again.

I flashed it to my lt28at with no problems, so have at it.

For those having problems downloading: do a quick search in your engine of choice for "udown 115 download." You should find a link to their downloader app (Windows only, boo-hiss). Click all the buttons that are glowing blue and you'll be ready-to-roll. It's a very easy app to figure out even if you don't read Chinese. The big buttons do what you'd assume they do.

    sorry to revive an old issue, flashed phone like 4 times already and still can't get room. When running step1.bat, should the phone be ON or in flashmode? And pretty much same for step2. Does anyone have a screenshot of what a successful step1 prompt should look like?
    Click to expand...
    Click to collapse

    Step 1 - Phone = ON, USB Debugging = ON, Unknown Sources = Checked Rom = GB .111

    Run Step1.bat

    Press any key to close command prompt. Turn OFF phone and disconnect USB.

    Flash ICS without wiping anything. Exclude baseband only (you can exlude partition and TA is options are available
    ScreenShot2012-08-16at54007PM.png


    Once ICS is flashed boot phone.

    Phone = ON, rom = ICS

    Run Step 2.bat
    ScreenShot2012-08-16at55623PM.png


    Once done you should have Root, ICS, LTE, and tethering ability.
