GDFS Problem for my W810i

[Blackcat]

so if u get the service cable the program won't give the "Protection card error" anymore? and heres a link for a cable is it the right one? Sony Ericsson Cruiser Cable: Sony Ericsson Multiserver cable
Does getting the service cable and the program, reformat the GDFS? what does it do?
Adreane I dont get the last procedure (And In 1 Step U Have To Made Unlock And Repair In Order 2made Some Order In Phone Then Use Flash Main 2 Flash It )

thats the correct cable, u need a working w810i gdfs to use a as a template theres 1 in the download section, u can use GDFSEdit - SE-NSE Forums to edit the CDA etc to match ur phone,
then u need SEMC 8.4 cracked also in download section it's a cracked there for free version, then u use this to write ur oringal old imei number which u can find on the side of the box the phone came in or old setool logs, now u use semc to flash and write in ur imei number to the new gdfs then do a full flash and ur phone should work
