I extracted the bootloaders and param.lfs from the latest AT&T Firmware, I897UCKF1 and created an OneClick ODIN package.
Flashing bootloaders is a dangerous deal but you take the same risk every single time you go back to stock using OdinOne CLick.
However, if you decide to go ahead with this method, you do it at your own risk.
I tested the package 3 times on my phone so it should be safe.
Now, you might ask why would you update the bootloaders again?
Mainly because I9000 bootloaders are not designed for I897. We've seen that there are a several differences between I897 and I9000 so is not hard to believe that having I9000 bootloaders might impact stability and even performance.
WARNING! Make sure you have a stable USB connection between your computer and your phone!
I really cant tell you how to check that, but is THE MOST IMPORTANT prerequisite.
WARNING! Key combos after flashing the bootloaders will be the same as in Froyo:
Vol UP + Vol Down + Power = Recovery
Vol UP + Vol Down + USB insert = Download
WARNING! If you have troubles connecting the phone to PC, download samsung Kies and install it to get the latest samsung drivers but make sure is not running while flashing the bootloaders.
Cyanogen MOD users, stay away!
The steps which you will need to take are as follows:
- Download the package from here
- Extract OneClickI897UCKF1-bootloaders.exe
- Restart the phone in Download Mode
- Run OneClickI897UCKF1-bootloaders.exe - with administrator permissions if on Windows 7 or Vista!
- Connect the USB cable to the PC and the phone
- Click "Start"
Note: ANY version of Android should work with these bootloaders.
Note: Some users reported that after flashing the package, the ATT logo didnt appear but some black screen with colored points. If that happens, flash the package again.
