Have you tried installing the original firmware for your U8510?
In case you haven't, the links can be found at the wiki: http://wiki.modaco.c..._Firmware_U8510
Within the zip file there will be a .PDF document explaining how to flash it. If it works it will restore your phone back to it's original state thereby losing any changes you've made. If it doesn't then you're screwed. Good luck.
yes i try and he say update fail, the possible problem is the "time machine"... if you read the U8650 and U8510 pdf you see compatibility models (upgradable_versions.txt i think)
file02.mbn appears to contain CRC checksums for some of the files. I'm guessing that it's not a 4096 byte checksum in this one, coz I can't find the checksum for larger files, so I just need to work out the size used... leave me on it
eg for the Time Machine rom$ hd file02.mbn 00000000 27 91 42 fd f9 ac 26 fc 87 21 01 3e 48 9a de c9 |'.B...&..!.>H...| 00000010 d1 64 af 9f 4d 42 4f 10 04 1d 09 9d |.d..MBO.....| 0000001c boot_versions.txt 2791 (bytes 1 and 2) upgradable_versions.txt 099D (last 2 bytes) version.txt 099D (last 2 bytes as well... ahem) file01.mbn 2109 file02.mbn 7A7A (It can't contain the checksum for itself) file04.mbn 42FD (bytes 3 and 4) file05.mbn 01C9
