Lenovo A780e Locked Network


Do anyone have an idea how to remove network lock on China Telecom Lenovo A780e?

When booted into download mode or whatever mode it is, all the written were in Chinese.

It appears like the phone may not be locked after all. I tried to check the IMEI but it was just eight zero digits that turned up. The phone can't possibly register on a network if the IMEI is broken.
How can I fix this without any service box?

Sorry for the trouble. I think the phone is CDMA. I didn't take a pretty good look before and the SIM slot was misleading. It is having MEID instead of IMEI.
