Sim unlock your TP2 for free

I read somwhere that Simlock=7,0 unlocks the scurity_flag on some HTC phones, so this is either not unlocked in the patched radio, or it's not what we are looking for. We need to keep looking.

I'm looking at other options too. It looks like the actual problem with the Sprint TP2 with USA GSM is not in the actual radio itself. I flashed the Sprint TP2 with Verizon ROM, which has the Verizon version of the radio, and it still did not work, if the Radio was the problem that would have unlocked it since Verizon's radio does not block US GSM frequencies.

I think that the problem of locking out the US GSM radios on the Sprint TP2 is in the NV ram. What I found so far is that one of the frequencies of the US GSM is not assigned an antenna for broadcasting or receiving radio frequencies. I think that the reason it starts working after flashing a US Radio, when it is Security unlocked, is that the flashing of the radio by itself forces the firmware to update the NV ram and assign the spectrum TX/RX correctly thus making it work. So in addition to having an option of unlocking security and flashing a US radio, we might be able to just activate the spectrum TX/RX for US frequencies. I could be wrong but currently I think that that's what is happening.

You mentioned a US Radio... perhaps a WU... obviously Olipro & cmonex have made changes to the radio code itself...

Yes the US radio I was refering to was WU. But I don't think that the Radio itself is what frees the TX/RX of the US GSM frequencies. As I mentioned before, I installed a Verizon Rom which has the correct Radio that works with US carriers on the Sprint Phone but Still it did not pick up US GSM frequencies, which tells me that the actual locking is not in the Radio itself. NVram has assignments to each frequency used and from what I saw, it assigns TX/RX antennas to each frequency. I found that one of the frequencies used by US carriers was not assigned any Antenna, neither for transmission nor for reception. I played with one of the flags and it looks like the phone started to communicate, on limited bases, with the US GSM towers. I know because the Reception bar on top displayed a different message after I did that. So I think that If I can find all the NV items that should be adjusted we might be able to to turn On communication between the Sprint TP2 and GSM frequencies used by US carriers without the need to reflash a WU radio. I just did not have time to work on this last couple of weeks. I've been too busy. I wish I had a Verizon TP2 to compare NV items on both versions to see what is different, and I would have been able to test the SIM unlocking on the Verizon TP2 too. I'm trying to get a Verizon TP2 phone, off of ebay, but couldn't get one for a reasonable price so far.

Yea, not in radio software, but needs both... a wu & unlock "security/Radio"... the new radio code "WU" is not the unlocker, just part of a 2 step process: 1. security/radio unlocker 2. WU patched radio (not the 2.37 verizon radio, but the "patched" radio WU.

re. I installed a Verizon Rom which has the correct Radio that works with US carriers on the Sprint Phone but Still it did not pick up US GSM frequencies,

& re. Yes the US radio I was refering to was WU

You said a bunch there... just want to make sure you're not thinking the wu is the same as the 2.37 verizon radio code... rather the xda link I post earlier... Some confusion in the past from others, as the 2.37 verizon radio (unpatched version) works great on a sprint phone :>)) ... in fact, has solved some XDAndroid issues recently... but has nothing todo with unlocking

Just to be clear

I don't think I'm confused. Here is the story. Security unlocking is needed to be able to install the WU Radio, but I'm saying we might be able to activate GSM frequencies without a need to install WU radio, thus not requiring Security unlocking. I heard that Verizon phones work with US GSM providers without flashing a new WU radio, they only need SIM unlocking. Given that, then the Radio that comes with Verizon ROM should work with US GSM carriers. But when you install it on a Sprint TP2 it still does not work. I think that the reason it doesn't work is because of the Frequency restrictions in the NV memory, which we might be able to change using QPST, without a need to security unlock or Flash a new WU radio.
