Manually Editing bands with R1CBU firmware


 

I have managed to edit the bands on Oleg's excellent firmware.

Here's a basic procedure:

Prerequisite.??
a: A PC running Linux with some sort of SD card reader.
b: A pretty good knowlege of Linux.? (It may be possible to do this in Windows but I'll not go there).
c: sqlite3 application on the linux box

Steps:
1: copy the params.db file from the DATA partition of the SD Card to your Linux box.
2: dump the params.db database to a file
echo .dump | sqlite3 params.db > <DumpFilename>
3: Edit the <DumpFilename> , lhe lines starting with INSERT INTO bands VALUES are the band limits.

4: Once you're happy with the resulting file, create a new params.db file
- rename (or delete) the old params.db file
- cat <DumpFile> | sqlite3 params.db

5: Copy the resulting params.db file to the DATA partition of the SD Card.

- I don't think file owner and permissions are important because the file finishes up on? a FAT partition but i keep it as root:root and 777.
6: Cross your fingers and try to boot up the X6100 !

If all fails, and nothing works you can always get back to a working system by copyong the latest RICBU image to the sd card.
Remember that any modifications will likely be lost when a new patch is applied or a new version of the firmware is installed.
