Acer Liquid Z2 Z120 IMEI invalid and no netword
 

Hi,

I have 2 pcs of Acer Z2 Z120 single sim with the message invalid IMEI. I fixed the IMEI using SigmaKey, but the phones do not detect the sim card and no network. I flashed using official firmware still same error.

Any way to fix this?

BR,
Florin

Have you got any news regarding the Z120? I have a single sim, z120 with the invalid imei as well. I have repaired the imei which has done absolutely nothing as far as I can tell, but the problem is the simlock. My box says it cannot find it, and I didn't backup the nvram before hitting the direct unlock button and causing this problem. p.s. NCKbox is the one I have, and I used the new 1.7 android module. Btw, when the imei is read, the last number that appears (5) is missing.
