Unlocking a K750i with W800i firmware CID 49

[shogun]

Hi. With semc_v8.4 you cannot recover K750i CID 49 Phones, so after you have read and cleared the locks with the service cable you may get CXC version not supported and then your phone will not turn on at all even though it is now unlocked. What I did at this point was use xs++ and changed the CDA of the phone with the service cable so that then I could connect to SEUS with the standard DC-60 cable and SEUS would recognize that the phone could be updated. At This point you just let SEUS do the update like normal and there you go, the phone is now turning on again and unlocked. Hope this may be of help.
