I purchased a T-Mobile T999 phone and need to unlock it.
I have tired the 4.1.1 unlock way but do not see the option [4] NW Lock NV Data INITIALLIZ.
I install the base rom for my device 4.1.1 but the radio is staying at UVUEMJC which looks to be a 4.3 radio i think. When I install the 4.1.1 radio baseband just goes to unknown. Can you please let me know how I can install the baseband for 4.1.1 so I can do the unlock.
Thanks
Steven

On the Top Level menu there should be something that says EFS Sync. I have yet to get another SIM Card to test, but all reports state that using that option produces the result you are wanting.
Did you try even though the baseband says unknown? Maybe try flashing an older rom too. If you did the full 4.3 update already you might be out of luck.
yes installed the 4.3 full install when i got it from ebay . Looking at getting a 4.0.4 rom just wondering why there is 3 different types for the T999 is there away to figure out which one i should use?
doing the unlock with baseband unknown nothing is on the menu to select.
going to restore my backup modem so that its working again but it will still be locked
thanks for everyones help so far.
My note 2 is from Telcel (México) and i'm having trouble unlocking the network,
i've tried the posts on General to no avail, when i dial *#197328640# the menu is different
(after network lock menu it says its missing), so i flashed ROGERS_MODEM_I317MVLALJ2 (Canada)
becuase thas was the OP (http://forum.xda-developers.com/showthread.php?t=2014982&highlight=telcel) option but i had no signal/unknown baseband,
but if i flashed GT-N7100_XXALJ2 modem i got signal but the same menu optiones were missing.
So i've tried Telcel roms for 4.1.1 and 4.1.2, i've read on forums where they use "boxes" to unlock that they had luck using
a Brazilian rom and then unlocking the phone, so anyone knows what can i do or if i flash brazilian firmware (N7100UBALJ1_N7100ZTOALJ1_ZTO)
to my phone (N7100UBALI9_N7100TCEALI6_TCE) is just like a custom rom or i may find complications?
Really need help guys.
I can't view any mobile networks nor connect them.
My SIM card isn't detected.
My basedband version is "unknown".
manually entering APNs does not work.
What can I do?
What baseband and bootloader are on your phone? You must ensure that your baseband, bootloader, and ROM are compatible.
I have a feeling your bootloader and modem need to be updated.
SGH-T999 got flashed to CM, everything works except I can't access my network. IMEI and IMEI SV and Broadbase are all showing as "unknown". Dialing the weird IMEI code crashes the dialer. Restored a 4.3 ROM, still couldn't get a signal. Tried installing the newest modem, no luck. What do I do? Is my phone completely ****ed and should I be looking for a new one?
Update: Tried reflashing CM again, now it says "No SIM card". I'm so lost.
Is the phone running the latest 4.3 bootloader and modem?

Hey I'm not sure what you mean by bootloader but I downloaded the UVUENC2 modem for T999 from this guy http://forum.xda-developers.com/showthread.php?t=1880987 and installed it. No luck.
The phone is a T999 or T999L?
NC2 is the latest for the T999. Does the bootloader match the modem?
Actually now that I checked the back of the phone it looks like it's actually T999L.
If it's a T999L, the latest firmware for the phone came out in October, 2014.
