I've recently unlocked my phone so that it can work with any SIM card, and I want to install CyanogenMod.

What I'm wondering is, since CyanogenMod is going to wipe most of the data on the phone, is the lock status going to be changed too? i.e. will I end up with a locked phone again?

Edit: My phone is HTC One M8, previous locked to EE. I got the unlock code from EE.

  • What phone is it, and how did you sim unlock it? Mention it in the OP

  • Do you have the unlock code with you or can you get it again? And do you remember how to unlock it? If yes, proceed to flash CM. Or else, try to find if unlock code is stored in phone (requires root I guess).

  • Actually I've already unlocked my phone and it works fine with any SIM. What I want to know is will it still be unlocked after I install CyanogenMod? I know that from CM I cannot SIM unlock (it has to be done from the stock ROM), so I need the unlock status to be preserved. Not sure if that makes sense.

CyanogenMod will wipe the DATA partition, all the CACHE partition and the SYSTEM partition while installing. It will not affect anything about lock/unlock of sim card.

    I confirm. After installing CyanogenMod, the phone was still unlocked.
