Here we go:
Convert BROWN to RED using DCU-60 for K750/D750/W800/Z520 (CID36 only)
1. Get the latest SE Flash plugin by Darkmen (v.10 or higher) and get a older version of far manager(with cid36 in description). new versions dont see cid 36
2. Go to Flash folder in your phone
3. Copy erom_db2010_red36_44000000_00020000.raw from attached archive to this Flash folder:
* Select Flash raw image option and check that address is 44000000 and length is 20000 according to the screenshot:
