I recently got a ZTE-T U880 and rooted it with SuperOneClick and installed CWR v184.108.40.206. I added your MOD solidchips_U880_v1.1. I wiped everything before flashing. The phone boots up OK, but now I get no signal (it says there is no SIM, or the SIM is locked - I tried 3 different SIMS none of them work), I cannot sign into my google account, and my PC no longer recognizes the phone. Any ideas? Please help! I am in China on China Mobile.
Honestly, i am not sure what's the problem with your phone.
One thing that comes to my mind is, maybe it's due to missing sim-toolkit apk.
I'm attaching "stk,rar", unzip it and copy "stk.apk" in "/system/app"
Let me know what happens?
