Any solution so far?
Were you guys able to get this problem solved?
Right now I am in the same situation.. if I change ESN/MEID I lose signal and I can't seem to change the IMEI at all .. DFS shows that it changes but after restart, only ESN/MEID is changed, IMEI always stays the same. I beleive that is the problem because ESN/MEID and IMEI aren't matching somewhere in the code.
Please do let me know if there is anyway to get the signal back.
