Note: You make any changes to the firmware at your own risk and without any warranty!
To patch the firmware, follow this step
Run UPLIBRIE_06160.EXE, this will extract three files UPLIBRIE.EXE, EBRCTR.dll and data.bin.
Rename data.bin to data.bin.orig (this file will be patched).
Copy FW06160_RxEN.bspatch, bspatch.exe and bzip2.exe to the directory where data.bin.orig is stored.
Run bspatch.exe data.bin.orig data.bin FW06160_RxEN.bspatch in a command box/shell. This command will patch the data.bin.orig and stores the result to data.bin. It is recommended that you check the MD5 sum of the new (patched) data.bin (see below) with md5sum.exe.
Connect the USB cable and AC adapter to Librie.
Remove the Memory Stick.
Reboot Librie and wait for the japanese USB message box.
The next steps are the same as in Sony's flash procedure.
Run UPLIBRIE.EXE and start the flash.
Hint: If the flash seems to be interrupted before the end is reached. Then wait five minutes, abort UPLIBRIE.EXE, start UPLIBRIE.EXE again and restart the flash procedure. Do not disconnect the USB cable or the AC adapter!
At the end of the flash procedure, disconnect the USB cable and AC adapter.
Librie should now have the English user interface.
