IMEI number change when I upgrade/downgrade OS(firmware)
I have a problem with my IMEI number, it change by it self whenever I upgrade/downgrade OS. When the IMEI number change, it always ended with number "0" and I can't use my BIS. I tried almost all 8830we v4.2 & v4.5 and still the same result.
The only firmware that works fine right now is v4.2.2.176
Is there anyone else having this problem too? cause my friend who use 8830we doesn't have the same problem like me? I really want to upgrade to v4.5 cause most of the programs I need only works on v4.5
