Excuse me. I do this a couple times every year or so and I'm still confused as to what's going on? And why do I have to keep doing it? I just got a new AIO sim card and it requires some code to unlock. Does that mean my phone unrooted itself when I flashed the latest stock rom in here, which btw finally a fully functional ROM, go figure... And what's the difference between using odin and this code sequence from the dialer method I found somewhere where you punch in a long *#blablabla# code which puts you in the matrix where you do a little dance here and there then viola your sim is unlocked? Anyway, if these are all unrelated, what is this unlocking my sim business and when the heck does rooting actually occur within the maze of steps Odin takes you. And why all this after I flashed the stock rom? It's supposed to retain your rooted state still no?

So let me see if I understand your statement. You flashed another ROM... and then got a new SIM for your phone, but when you turned it on it will ask you for an unlock code? Rooting and unlocking are two different things, you can be rooted and not unlocked... so what you need to do is follow the unlocking method. Or... I don't seem to understand what you mean, can you be a little more specific?

Sorry. It's confusing. I'm stuck at the sim unlocking part, where you can put in a code from the dialer as shown here: http://forum.xda-developers.com/show....php?t=2024514

Unless you know your unique code to unlock your sim whatever that means. So I should still be rooted but now somehow still locked or something? Or is it just the sim that is locked? I'm fine with my old tmobile sim/account in place as in as I'm writing this, but as soon as I pop in my aio sim, back to that thread but id need to install uvle1 but b4 I do all that I just want to know what and why I am doing. Should I continue? What exactly will I be doing? Thanks

Sounds like right now your phone is carrier-locked; i.e. your phone will not work with a sim card for a network other than T-mobile's. Rooting will not unlock your phone for use with another carrier's sim card, however, the instructions in the thread you linked in your post will. If you really want to use that AIO sim card without paying for an unlock code from T-mobile or some other source, then the instructions in that thread are probably the best way to make it work. UVLE1 identifies particular modem/radio firmware and stock ROM that needs to be installed on the T989 in order to have access to the menu items required for the unlocking process. You can switch to the most recent radio or any ROM of your choice afterward without losing the ability of an unlocked phone.

My friend, you have a lot of studying to do....I'm sorry, but you seem awfully confused. No insults intended.

Please read all the stickies and then some.... before you attempt anything on your device. Very bad things can happen if you don't understand what you are doing and exactly how to do it.

Good luck!

2 search terms for Google will answer everything too.

One: how unlock t989 free XDA

Two: how root t989 xda

Those will get you started. 😉

Okay in up to speed now on all this. I've known this stuff at different points in my PDA phone assisted life but due to my own RAM deficiency i easily forget this stuff. Especially since I only learn it over a few days of the year.

Anyway, I forgot I never unlocked my phone because I never even needed to till now. My phone had always been rooted as I've been swapping ROMs for a while now. Well I'll go work on that solution now. Thanks for the replies
