I was just wondering what the point of doing this is? Like is it just so I could use like the Verizon CDMA network or what?
I have the Sprint Rhodium400 and its STOCK radio version is 2.32.00.WU, so I mean according to what I read this is unlocked.
anyway, I was just wondering what if any point doing the Security Unlock has for me?
the SIM unlock is to use it on US GSM networks such as ATT and TMobile, it doesnt allow it to work on other CDMA networks like Verizon
Oh ok, thanks for the heads up on that one.
Good looking out (I was wondering about that for the longest time)

If your radio says WU that means that you can use any GSM sim card (not CDMA) on any network w ur phone. Security unlock - HSPL will let you flash your phone with custom roms. You can find more info about HSPL by following thread by OLIPRO. Of course thank him for his work. Have fun flashing.
FYI... Do not flash your phone w CDMA roms.

This is not true. The stock radio in verizon roms has a wu but all sims are locked minus the stock vodaphone sim. The locked sim does not have to do with the radio on the verizon tp2.

first. he has sprint..
second. verizon doesnt have wu.. unless you flash it w one (stock is always wv)
i do give you credit cuz i did not know that wu may still be locked.
no hard feelings.
peace
The Sprint TP2 has no SIM lock in the system, but the radio ROM is lacking support for the US bands. So while the Sprint TP2 will accept any SIM it will not get a SIGNAL in North America unless you pay for the security unlock and apply a patched radio.
The Verizon TP2 HAS a SIM lock in the system, but the radio ROM has full support for the US bands. So if you just want to use a SIM card, then all you need to do is get an unlock code from Verizon.
Both version radios have support for Euro bands.
Default behaviour:
Sprint = Use any SIM you want, but only get a signal in Europe and Japan when in GSM mode.
Verizon = Can't use *any* SIM except Verizon until you unlock, but to unlock you can do it by requesting a free code from Verizon CS.
so u can use ur phone on a different network (phones with sim cards obviously)

Yes. Once unlocked, you can switch the phone to GSM mode and use any GSM SIM card.
I do have Sprint (The Rhodium400).
It has been HSPL Unlocked for about 6 or 7 weeks now, just was curious about the Radio unlocking stuff (as I have never messed around with it).
I have already run the gauntlet of the various Custom ROMs out there. All (well most of) them seemed to be very VERY well built, however none seemed to suit me to quite 100%, so I have been working on my own for about 3 weeks now give or take.
It is a slow going process (mainly due to working so much), but it is very fun and a learning experience none the less. Looking forward to the day it is finished (So that I can start on the next one, lol).

..also thought I read somewhere in CMONEX thread a recap saying if unlocking sprint radio/SIM you'd be able to use Verizon towers... (will look for post & put hyperlink here soon)
also, from ppc/cmonex sticky:
BIG NOTE: if you have the Sprint branded TP2, then after running this SIM/Sec Unlocker, you'll need to flash a patched sprint radio (in other thread) to finish the process.
... sprint is a Security (CID) unlocker, which needs unlocking first, then a "patched" (unlocked?) sprint radio also...
"Originally Posted by Syriel View Post
By default, the stock Sprint radio only has support for GSM 900/1800 (Euro bands) even though the hardware supports GSM 850/900/1800/1900. When you flash Oli's WU radio to the Sprint TP2 it re-enables support for GSM 850/1900 (NA bands).
The reason that Sprint disabled the (NA bands) is because the Sprint TP2 (unlike the VZW TP2) is SIM unlocked from the factory. The VZW TP2 ships with full band support, but it is SIM locked from the factory.
"
Guess I'd just make it simple: Sprint needs a band enabler - 850/1900 (security unlocker?) & then a radio that works on it... (patched WU)
So I have Sprint service on my TP2.. if I unlocked it would I be able to receive a call from either network or do I have to manually select one and swap back and forth?
I can understand having a default outgoing radio (choosing CDMA or GSM).. but it'd be more useful to have the ability to take make use of both lines..

you would have to switch back and forth
and of course have a SIM card from a GSM provider like ATT or T-Mobile
Verizon itself uses the XT1028
But if I got a XT1031 which is from Boost, could it be activated on Verizon?
I assume it would need some kind of carrier unlock but not familiar with cdma vs gsm.
After much more research I've come to the conclusion that it would be impossible because Verizon restricts devices by imei and knows what devices are real verizon or not.
So even it had the radio for Verizon, it would not be allowed on the network.
I have a rooted S6 edge unlocked for US Cellular (G925R). I see a lot of ROMs here on XDA but moslty for other variants .
Is there a way to safely flash a ROM belonging to different version for the version that I have ? Is there a workaround that can accommodate this ?

I assume the G925R has an unlocked bootloader, which is how you got root.
You should be able to modify the updater-script in a ROM to allow it to flash properly on a G925R (zerolteusc), I guess a ROM for the T-Mobile S6 Edge could be edited to work on a US Cellular.
Don't try it without confirmation from a more experienced member though. I'm just saying, editing the build prop will work, but T-Mobile is a GSM based carrier whereas US Cellular is CDMA, so not sure if the ROMs for the G925T will work on your phone.

Thanks, I will look further. Pardon me if I am asking a silly question but I see an option to choose the preferred network mode as LTE/CDMA or LTE/GSM. Also my device has a SIM card slot so is this device capable of both CDMA and GSM ?Currently I am using a Tmobile SIM in it and I have also tried an AT&T SIM, both worked as I could make calls. I am asking this as I am planning to use this phone outside US and if the device is CDMA only it will not be able to work on the networks outside.

No problem.
Pop in a SIM Card of your choice and you can use the phone on most GSM based carriers even abroad.
You mentioned that AT&T and T-Mobile were working, so you're all set.
Verizon, US Cellular and Sprint devices are CDMA but they have a SIM slot. So they will work with GSM carriers provided they are unlocked.
Oh, and about the network mode, select the right one depending on your network. If you're on a CDMA network, choose LTE/CDMA or if you're on a GSM carrier, choose LTE/GSM.

Does any one know if a sprint version U11 will work on verizon ? Yes no CDMA compatible with verizon but as published on line verizon no longer requires a phone to have CDMA as per the unlocked version being able to work on verizon and the verizon version itself having no CDMA support either.
I"am asking because I know someone that can get me a discount on a sprint U11 I just need to know if it will work on verizon.
I tried looking up the gsm bands and all I get is one set I cant find any just specific to the sprint version. I know that even if verizon wont activate it I could just pop in a sim that was activated in a verizon phone previously.
Here is a link to an article that lists verizon no longer requires phones to support CDMA to be activated on their network as they are getting rid of CDMA.

Question for those who know more than I do... If someone gets a sprint S8+ unlocked (A SPRINT DEVICE THAT HAS BEEN UNLOCKED NOT A FACTORY UNLOCKED DEVICE) to use on GSM (T-mobile, AT&T, etc) will it get all the GSM/LTE freqencies and bands for usa gsm services like T-mobile, AT&T, etc... Or are the SPRINT S8+ crippled on the GSM frequencies?

If you flash the U1 firmware that comes from the unlocked US phones, you should be good if the phone's already network/SIM unlocked-that firmware doesn't have the carrier bloat, but it detects the SIM card inserted and will adjust the network stuff accordingly so that it operates on the right bands, etc. If you'd prefer to have all the carrier apps/ bloat as well, there are several threads on carrier switching. Flashing the U1 firmware is fairly straightforward and easy, and most carrier features work; Switching from Sprint firmware to another carrier's firmware is a bit more involved but still totally doable. You're going to have to do one of the two though.
Edit: All of the US models have the exact same hardware, with all of the same radios...the unlocked model is the exact same as a variant from T-Mobile/Sprint/etc. It's just the CP & CSC firmware files that dictate the network stuff.
