I recently discovered how to fix imei on our Spica.
(Added support to i5800 too)
I can not explain the process, as this would be very dangerous in the hands of someone with bad intentions.
I need two photos, one showing the imei on display, and another showing the imei under the battery, without this condition no process any request.
Restore imei on spica will have a cost of 6€(Paypal only)
Contact me with a private message to request this service
There are no discounts, do not obligate anyone and my work it costs me (because I test on my phone and that makes it inoperative but the time it takes me)
If you do not want to pay 6€ I'm sorry but my work and my time is precious to me and not much money for the work.
