I dont know how the other was modded, possibly dynamic. This is a SSv2 mod and should be safe. There is a risk, but it is likely minimal. I have modded 6 gateway bios, as they seem a bit more difficult, and they have all activated..It is up to you though. Just be sure you read the recovery for gateway. I dont know what more to say.....Good luck and enjoy... A brick requires either board or bios chip replacement. A bad flash can be recovered. I am not seeing this brick..but you never know....
That is the only way...If you have a programmer, the bios can most of the time be modded..you cannot flash without the platform data..it is not written to EEPROM, so it cannot be backed up.. I think a programmer does not need this data, as it has its own software...
