Guys
I've searched the forums and realise I can buy a SIM unlock code for my Blackstone, however I'm trying to clarify the following.
1. If I install a different ROM do I still need to buy the unlock?
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
Thanks in advance for the help.
Regards
Its an unlocked phone my friend so obviously you pay a higher price for the phone itself able to use with any sim card. Carriers phone that are branded with the carrier logo are usually cheaper with a plan that could cost more then the phone overtime and is locked to the phone carrier which requires a sim unlocking code to use with other sim cards/ other carriers.
The answer to that is you can install any rom on the phone and if it an unlocked htc touch hd which you paid a lot for then it will be unlocked forever
if its locked to a carrier im not sure about that maybe someone can clarify.
any ideas please guys, I get the phone in a couple of hours.

Anyone?
Try to keep this short
1. If I install a different ROM do I still need to buy the unlock?
No Simlock is based on the radio and hardware (short version).
Once unlocked yoiu can up your rom and your radio, it stays unlocked.
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
Got me lost on this one.
Simlock is based on radio and Hardware.
So your IMEI is part of the phone which is either Sim Locked or not.
If you put your sim into what ever is in phone is in your car your number will be the same.
Once you have sim unlocked a device it remains unlocked.
Like I said you lost me.
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
No - Once done it remains unlocked regardless of rom or radio upgrade.
(and if you buy a new Simlocked Blackstrone you cant use your old code as the lock is based on the hardware)
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
--->point me to the page that you feel needs updated, i will have a go at it.

ive been trying to get my samsung s4 SGH-i337m Bell unlocked.
ive tried a few internet companies and they said they cant unlock the phone for many possibly reasons.
ive swapped the motherboard with a smashed screen phone because my first s4 had the sim card issues and many other issues so i swapped with a newer mobo.
now i want to unlock my phone to work with my carrier (wind mobile) but im not finding any ways to unlock it myself. ive tried using menus trying to unlock "PERSO SHA256 OFF" through the menu but i have 4.4.2 and 4.3 is the android version that can be unlocked easily through menu screens. once the phone is at 4.4.2 it seems like its unable to flash back to 4.3.
ive got the idea to change the IMEI so my phone will be basically original but with the newer mobo...but im having problems changing my IMEI.
ive used QPST and changed the hex code and reset the phone and it wont take and ive used NV reader and still doesnt seem to change the IMEI. each time i check my IMEI its still the original.
is there a way i can unlock it or change the IMEI to my first phone and use my first unlock code to unlock my phone with the new motherboard?
thanks
Changing your imei is illegal in many countries. You went get any support on doing that on XDA.

PROBLEM: A sprint V20 was brought to me to have the carrier swapped from [Sprint] to [Cricket]. So far sounds easy right? Read below...
Please Review the following of my step by step :
ESN IS LISTED AS CLEAR ON SWAPPA, please note that means this device "should" not have issues (first thing I checked)
Under APN settings there is no way to +add APN as there is with every other phone I have touched. Is this because it was a lease?
I considered perhaps rooting the phone, throwing on a custom ROM, and therefore hopefully having that added. Looks like bootloader is locked.
Of course, I am 1 security patch too late, DIRTYSANTA will NOT work on my firmware.
Searched everywhere, seems as though you CAN NOT roll this back.
Next I looked at using Chimera Tool to roll back the firmware. I cannot seem to find a ZV5 firmware file.
Next I looked at using chimera for IMEI repair. I figured if I change the IMEI just long enough to modify the APN settings then revert it back, I would be golden. Chimera gave me an error of not having access to the ports. I tried to dial in the following codes to enable port check but none have access to the "hidden menu". 277634#*#, 3845#*997#, *#546368#*997#. I tried to factory reset the phone, no luck.
I was able to use ##DIAG# (##3424#) and enable DIAGNOSTIC mode, yet this seemed to do nothing about ports.
I was able to enter ##DEBUG (##33284#) but there is no ability to ediit in here. Although at one point in time I was at a screen asking for an SVC code, no idea how to get back there though.
Tried to do a "fix" on Chimera, which is the same as refurbish on LG Up (I need the phone in factory condition), but apparently this device does not support refurbish mode. So flashing software is not wiping anything.
I cant seem to boot it into recovery, for god knows why.
QUESTIONS I HAVE
How do I completely wipe the phone of all user data?
How do I open these ports since the codes provided bring up no menu?
Since sprint is the only one recognizing the bad ESN, is this device able to even swap carriers?
What reason would APN not have an ability to edit or modify?
What additional tactics can I use to get my goal accomplished?
Hopefully we can brainstorm together
Please refer to this thread, it should work and do what you need to withthat apk. I belive its under IOT menu then under lte and put it in lab mode and turn on all the bands plus adding APN .. Im not to sure but ask the OP im sure he is way more helpful... asfar as adding the apn without this you need root to be able to do this and for nonroot i believe you must use ADb commands to tgecdevice and add them from there. there is threads oithere....

if the esn is now listed as unpaid, or lost /stolen cricket will not be able to add the esn to their system either. its a nation wide list that blacklist's the device.
Unfortunately changing the apns etc wont fix this.
ZV6 currently does not have a way to be rolled back, so there is 0 root/custom options.
APNS have been blocked by sprint for some time now and using some root methods they can be unlocked, in your case you wont be able to access them due to being unable to root.
Tools like CDMA WORKSHOP, QPST, QXDMA, etc may be able to write the apns and such you would need, if you could get the msl for the device, but if it is no longer active, and the device has a "bad esn" then you wont be getting that from the carrier. I dont believe youll be able to access the nv items etc without it and probably not going to be easy to locate the msl.
##diag# is how youll talk to the device on cdma workshop etc, youll need to go to your installed devices and change its com port to a port thats free and remember the port as the tools need you to select that port, but again they wont work for you without the msl anyways.
so in a nutshell, it looks like your best option is to sell the phone as parts only, or if recently purchased on swappa and it was listed good esn and its not then file a report at-least to make swappa aware.

Is the SPC the same as the MSL

Yes
What if I have the SPC?

As of this point the warranty on it has long since expired (for both Motorola and Target, the place where it was purchased) so we're pretty much willing to try anything to get it working
I've got with me here a G5 Plus XT1687 that, at best, I can describe as being in a state of "limbo". Its bootloader mode can only be set to flashing_unlock and flashing_lock. We've obtained the unlock key from Motorola's tool and have tried fully unlocking the bootloader multiple times following the guide on XDA, but it seems to not want to accept the command fully and remains on flashing_unlock. When I try to relock everything to start over, it gets stuck on "flashing_lock" and won't go back to fully locked. When it's in the flashing_unlock state I am able to flash ROMs and TWRP builds, so technically it's unlocked.... sort of. I'm unable flash SOME things, like new bootloaders or gpt partition tables, but other things will work just fine, albeit with the occasional "invalid signature" message following flashing. But this right here is only the start of our problems.
Having purchased the US retail XT1687 model, it was supposed to come carrier unlocked out of the box. My friend who got this didn't have a SIM when he got it at the time, so he just used it as a WiFi-only media player sort of thing. When he finally got a T-Mobile SIM and put it in, it asked him for an unlock code. This of course doesn't make any sense, because we didn't get this from a carrier, so why would it be locked to anything in the first place. It was tried with multiple different SIM cards, running multiple different ROMs (and even stock firmware) all with the same result: the phone seems to be network locked to nothing at all.
I tried calling Motorola and they said they can't make an unlock code for us since it's the carrier that decides what algorithm to use for network unlock codes... but this phone didn't come from a carrier, so I don't know what to do.
Fixing the bootloader thing would be nice, but my main goal here is to try and remove this nonsensical network lock so my friend can actually use it with T-Mobile. At this point he doesn't want to send it back (since we'd have to pay for the repairs, and he got a cheap LG to use as a primary phone anyway). That being said, we're pretty much willing to try anything to get it working. Any suggestions?
EDIT: just want to mention as well, we've never had a problem with the IMEI being set to 0. It's always been what it originally was
Hi, I have an ancient D802 that is locked to Three UK. I have decided to resurrect it on EE but when i put the EE SIM in it doesn;t prompt for an unlock code. So, I've been into the hidden menu and it says that the phone is permanently locked and cannot be unlocked. I've had a look around and can see others asking the same question but no answers. Any way around this or shall I just throw the phone away?
TIA
