Downgrade works for unlock BB5 phones using MT-box PRO??
 

e.c. MTbox PRO doesn't support unlock for 6280/6288 ver. 6.43 .

if downgrade phone to 6.10 then is possible to unlock it??

Upto 6.10 versions (6280/88) - handsets can be unlocked. TESTED. Though there were some handsets which could not be READ by mtpro + TP {i doubt some prob with hardware i.e faulty track near pop port or water rusting etc.}.

Regarding 6.43 .. not got any such handset yet. So cant guess.

There were some 6233 and 6234, which were quite challenging cases. Also one thing that came to my knowledge > phones having SP data damaged .. FFFFF etc.etc. also were not unlocked by this box.

6300 completely unlocked {though it is under TESTs only}. 5200 - 5300 also ok.
BUT problems were in unlocking models like 7370, 7373. N91 not supported at all. 5500 also not supported.

REST i ve not came accross variety of handsets yet, so cant tell much.

I received 6288 which I tried to downgrade from 6.10 to 3.81 and now its sp area is corrupted and displays all FFFFFFF like below posted log:

IMEI: 355547012426749
Operator: FFFFFFFFFFFFFFFF
Profile bits: FFFFFFFFFFFFFFFF

Is it possible to unlock this phone now?

No this phone have corrupted simlock arena now you can't unlock it. Must write 308 filed from pm and check that this will work .bye

I read the field 308 from working 6280 v6.10 but I am unable to write the fields into phone. MT-BOX displays Unable to authorize use SX4 or something like that...
Any advice

reflash again to 6.10 and restore simlock backup to be ok then unlock it
