OK, it might sound silly but this is what I am trying to do.
I have ex-Sprint Touch Pro 2 phones (so CDMA versions) that have been unlocked using the Olipro htc-unlocker tool. The phones work fine when the sim cards are in the phone and GSM only is selected (I use many different custom roms, no problems). Global mode or CDMA is obviously no good as they try to use sprint network. If the sim is removed (or swapped for a different sim) or a reset is done, when the phone is turned back on it attempts to activate on Sprint again (as it has reverted back to global or CDMA mode). Is it possible to stop this from switching back to CDMA or Global when the sim is removed (or a reset is done), so that the phone stays as GSM only. Ie, so that if a sim is removed it would just say "Insert Sim" or similar.
What I have already tried:
Changing/Removing settings while in Diag mode (both phone mode and PC mode). This includes deleting ex-phone number and voicemail settings etc, even disabling every CDMA option I can find.
Flashing a custom ROM for Tmobile only (designed for CDMA version phone but setup specifically for Tmobile settings).
What I would like:
A ROM (designed specifically for the CDMA version) that has no CDMA option at all, or at least the factory/reset default is GSM only, not global and not CDMA (and where it doesn't revert to CDMA mode if a sim is ever removed).
Or
A setting perhaps in the diag mode (##3424#) that would allow me to completely disable the CDMA radio so that if no sim is in the phone then the phone is useless.
Or
Some other way of achieving what I have said above.
If I can offer any help in making what I have said above more understandable just ask, it makes sense in my head.
I have flashed / unlocked / modified many phones in my time but this problem really annoys me, any help would be great.
Thanks
I'm really not an expert on what you're asking (sorry..), but if I understand you correctly, you're saying that a CDMA TP2 can actually by used on a GSM network?? That would be something for new since I thought that CDMA phones had different hardwares than GSM phones. Do you have a link on that topic?
Correct, the CDMA version still has a SIM slot for use when you are outside the US (called a Worldphone). Using the unlocking tool provided by Olipro (link provided below) the phone can be unlocked to work with GSM SIM cards here in the US.
**Do take note though - if you ever flash a ROM onto the phone it is still considered a CDMA version not a GSM version - Don't flash a GSM ROM onto this type of phone**

My problem is that I often remove or swap SIM cards, use different GSM networks etc and want to completely remove the existance of the CDMA network (as the phone always reverts to CDMA if a sim is removed or changed).

I would love to have this exactly,I am using a sprint touch pro2 on tmobile,and it drives me crazy that it keeps jumping back to global mode.
I had started to wonder if I was the only one who wanted this.
It must be possible (somehow) to set the "Mode of Operation" not to change if a SIM is removed.
what does it mean that my phone is not personalized in any option of the sim unlock process, in fact i hace 10 attempts to unlock my phone
I'm confused my old x10 said it was network locked
Hi,
Someone know how to unlock sim, without use IMEI unlock code payment)?
My original HTC Desire X had Hboot 1.25.00, Ratio 1.15.40.04, CID ORANG309 (lock sim).
After a few weeks I have Unlock HBoot, I made S-OFF, it´s Rooted, I have SuperU and super CID 11111111
I have flashed Custom Kernel ViMiRo ROM v1.0-1 (ROM1.10.401.4). and ROM 2.20.401.6_Deodexed
Now I´m stuck unloking Sim.
Can you help me?
Thanks
Normally if you have a super CID (11111111) your sim card is unlocked
A handset can be unlocked by entering a code provided by the network operator. Alternative mechanisms include software running on the handset or a computer attached to the handset, hardware devices that connect to the handset or over-the-air by the carrier. Usually the unlock process is permanent. The code required to remove all locks from a phone is referred to as the master code, network code key, or multilock code. There can also be multiple levels of locks placed on the phone by networks, which block the use of other networks SIM cards. These are usually referred to as "Network" (NCK) or "Service Provider" (SPCK) locks and can be removed using the corresponding unlock codes, which are unique to each phone depending on the its IMEI.
Typically, a locked handset will display a message if a restricted SIM is used, requesting the unlock code handsets may display different messages such as "Enter special code" or "Enter unlocking code" or in some cases the handset will simply display a message stating that it is locked. Once a valid code is entered, the handset will display "Network unlocked".
The unlock code is verified by the handset and is generated by the network provider, typically by an algorithm such as a one way hash or trapdoor function. The algorithms used in many handsets are based on the IMEI number and the MCC code and have been reverse-engineered, stolen or leaked. Most handsets can be unlocked using software that generates an unlock code from an IMEI number and country and operator details using the algorithm specific to the handset. Other manufacturers have taken a more cautious approach, and embed a random number in the handset's firmware that is only retained by the network on whose behalf the lock was applied. These handsets can still be unlocked, but need to be connected to special unlocking hardware that will rewrite the part of its firmware where the lock status is kept, and often even recover a phone that is bricked or completely damaged in the software sense. However, other handsets, notably the high-end PDAs and smart-phones, can be unlocked by the use of software that can read the unlock code directly from the firmware. In case of Android handsets, the bootloader of the device can be unlocked to flash a new CID number(11111111, which indicates an unlocked device) and hence the SIM Lock is effectively removed.
Most handsets have security measures built into their firmware that protects them from repeated attempts to guess the unlock code. After entering more than a certain number of incorrect codes the phone becomes hard-locked and unlocking hardware must to be used in order to unlock them.

I have a Moto G XT1548 that I want to use with Mint Sim. When I insert the Mint Sim card, I'm not prompted to enter an unlock code - I received a CDMA unlock code from an online service.
I did a lot of searching, but nothing seems to be working for me. I can't even seem to get the msl/spc code for this phone so I can unlock the ##DATA# menu.
Any advice?
I had no problems unlocking the bootloader and installing lineage os 7.1.x. I'm currently back to running the stock osprey sprint 6.0.1.
Thanks.
Anyone?
No advice from anyone here?
I'm currently trying to brute force the ##MSL#. At max, it would take ~30 days.
There currently is no way to unlock a Sprint device without a Sprint SIM unlock code.
Getting your Master Subsidy Unlock code doesn't help on this device, you can't unlock it from there either. In Sprint devices since February 2015, DSU and MSU are two distinctly different things.
Most (not all) online unlock code providers are just scams, avoid them if possible unless they offer guaranteed refunds.
My understanding is that I need the msl so I can set a nv param which will enable the sim card unlock so I can use the code that I bought.
Does this make sense?
If not, what can I do with the phone?

I am not familiar with what your trying to do... but there should be no need to do any "pre-unlocking" in order to use a DSU (Domestic SIM Unlock) code on a Sprint device, but I am not the expert in Sprint either, but @MotoJunkie01 is kind of our resident Sprint guru (well, he is pretty good with all things Sprint anyway) might have some insight here.
I would advise 4 possibilities, and the first depends on a number of factors I have no idea about.
1) Get a friend who has a Sprint post paid service, and has for over a year continuously, to put their SIM in the device and use it for a couple days... then request an official unlock code. This requires that you have a friend you trust with Sprint service and that Sprint will unlock for it's customer's like AT&T (I can unlock any AT&T device with a simple web page submission since I have been a customer for some time). Then it will be GSM unlocked in the US.
2) Sell/give/trade it to someone who has Sprint service
3) Switch your service to Sprint or one of it's MVNO's
4) Use it as a WiFi only media device

I agree 100% with @acejavelin's analysis of your options. There is no known user-end mod or hack with which to perform a Domestic SIM Unlock of the xt1548. So the options he outlined are your only viable choices.
There are some Chinese hackers who have claims of being able to perform a DSU on the xt1548. However, their method has never been proven, nor have their claims been substantively backed up.
If I were to call up Sprint and ask for the MSL, they would give me a 6 digit number, right? ##MSL#?

Yes. I have MSL/SPN numbers on all 3 of my xt1548 devices. Trust me, you can edit all you want with the MSL and you still won't SIM Unlock it. These devices are network locked via encryption in the partition index (/hob, /dhob, /pds). As of now, nobody has figured out a way to decrypt these network restrictions.
The menu used to edit with the MSL on the xt1548 is ##DATA#. You can edit a lot of parameters on this device with the MSL, but unfortunately DSU isn't an option. There are MSL mods to stop data throttling on plans with limited high speed data, for example.

Is your xt1548 Sprint, or one of its MVNOs like Virgin, Boost, FreedomPop, etc? If you have Virgin or Boost, their respective websites will give you the MSL numbers via the activation page. Once you enter your IMEI (MEID Hex), and prompt for activation, you can select "Pay Later with a Refill Card." Your device will be tentatively activated, a phone number assigned, and the MSL code will also be displayed under the "Activation Status" heading. I'm not certain if the same holds true for Sprint prepaid on their website, but it's a possibility.

Yes. This worked. I now have the MSL code.

You can pull some nice mods with the MSL, like hard coding APN settings, network configs, reverse tunneling toggle, bypassing data throttling, etc. Unfortunately, however, due to the encrypted network restrictions, no MSL mods will enable the device to recognize a GSM SIM card.
I have one galaxy s8 which was claimed to be unlocked b4 buying it,put in my sim and it's writing "invalid sim card,sim card not supported"if i go to settings and search for available networks,it will bring different networks but wont allow me to register on it.if i try to call...it will say "not registered on network"
I made an enquiry and they said if it is locked,it should prompt for an unlock code immediately i put my sim inside.even if i wana unlock again,d phone is not asking for any unlock code neither is it asking for unfreeze code.i also tried secret codes with it and it is not working #7465625*638#.it is a branded at&t phone
You may need to configure the APN for the new carrier manually. Go to settings, connections, mobile network, then APN (Access Point Names), select add and type in new APN settings.
However if that doesn't work, It may be hard locked. Meaning that an invalid sim unlock code was entered too many times. In my past experiences if it doesn't prompt you for the code when you enter a new sim card it is either hard locked or already unlocked and needs the APN settings configured. However after inserting a new sim card the phone would normally configure the APN automatically and only on occasion would I need to modify it to get data/text working properly.

invalid sim card,sim card not supported means it is locked device, i would like to help you to unlock it if you're interested
I'm facing this same issue. When I got the phone I installed an unbranded firmware (XAA/XAA/ATT) and I've since upgrade to Oreo. I can't seem to restore an ATT firmware so I can be prompted to enter the unlock code. Any suggestions?
make sure you using non at&t sim and it must be an active sim card. submit an unlock request to at&t on their website or use an unlock service like attunlocker.us to get your code.

The issue is there's no prompt to enter the unlock code.
is the SIM card active that you are using? what SIM is it?

Yes, it's a T-mobile SIM.
Sorry to necro, but does no one have a solution for this? I've seen plenty of threads such as this but very few solutions.
Necro double-post, I'm really asking for it...
First, you have to get an unlock code from the carrier. I had AT&T and it told me my phone was active under an account (previous owner). When you call AT&T and ask for an ulock they loop you to the website and you can't progress there, so you just have to ask for "customer service" twice and then get to the second level support. They can get you an 8 digit code for unlock. But I still never got prompted for the code and neither AT&T (5 calls), Cricket (3 calls), or xFinity (3 calls) could tell me how to get to the unlock screen. The following did it.
My solution was to use the following method, as found on https://www.tenorshare.com/samsung/samsung-unlock-code.html:
Step 1: Open the phone and type #7465625*638*# in the dialer.
Step 2: Then, it will ask for the Samsung Reset Code, it is an 8-digit code.
Step 3: Provide it and you will be done.
