[Q] How unlock sim on HTC Desire X? - General Questions and Answers

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.

How to input unlock code for G2x

(mod, please put it sticky for reference)
First of all, you have to obtain unlocked code. You can obtain from T-Mobile if you passed 3 months after you requested last unlocked code, and the phone passed 14 days (30 days in CA) trial. It is recommended to request it through online chat to ensure it's 100% correct (you can obtain your IMEI by key in *#06# from dial. Make sure you triple-check it).
After you obtained your unlocked code, go to dialer (you don't have to have foreign SIM but it is recommended to test) and input
2945#*999#
(this method works with ANY LG GSM Android phone because #*xxx# is actually your phone model. For example, Optimus T is P509 then #*509# and G2x is P999 so #*999#)
Enter unlock code correctly. Once you verified everything is correct, you can press the button below, and the phone will reboot, then the phone is unlocked.
-----edit-----
Notice: you must with stock ROM in order to make it work. If you flashed it with custom ROM, use your Clockworkmod to backup your current ROM and install stock ROM (2.2 in order to root it).
After you successfully unlocked it, you can go to CWM and restore it back.

Did you purchase from corp store or from my t-mobile?
I wasn't asked for proof of purchase.

This is strange because I was not asked for receipt for the phones purchased from corp store or my t-mobile. It may be possible you didn't purchase under your phone number.
If you are in good standing, thet wouldn't ask you for anything. I bought my g2x off CL, and I got my unlock code through email with no problem whatsoever, got my code 8 hours after i've requested it.
sweet added to the sticky (rollup and forum).
Thanks,

It didn't work on my Optimus T. I exactly followed the instruction but there's NO prompt when I put in old Wataniya (from Kuwait) SIM, so I did a search and found the working instruction.
It was used for Optimus P540, but I found it also works with Optimus T (change to 509) and G2x (change to 999) and I got an unlock prompt even with T-Mobile SIM.
Got my unlocked code from tmobile within 12hrs for my G2x that I purchased from ebay. All the lady ask for was the IMEI number.
do u noe the unlock code for phonetestmode or hiddenmenu?
Just wanted to say the OP was correct. I used the 2945#*999# to unlock my G2X and it worked perfectly. Only thing I should have known is that it won't work if you are on Wifi Calling. It needs a GSM signal to request the unlock.
P.S. I got the unlock code from unlockthatphone.com for $15. Took 12 hours to get it.
Wanted to say thanks for this thread. I chatted with a T-Mobile representative yesterday via the website and the request got sent in around 12:30 Eastern. Twenty-three hours later I had the code waiting in my inbox.
I decided to try an old, deactivated AT&T SIM I had in an old phone and it worked just fine to enter the unlock code. I would have used the Dialer method mentioned in the OP if that didn't work though, as I was able to get the unlock text box by entering the Dialer code as a test yesterday.
Thanks for the information, everyone!
I found this guide to be very helpful. I thank you as I am still waiting for my phone to arrive.
So unlocking does what? You can use it on ATT with what internet speeds? You can also use it in other countries to right? Whats the data speeds though?

I got my unlock code from t-mobile. I put in an ATT SIM & nothing appeared - so I tried this method. What happens to me is my phone says "USSD code running..." and then it just sits there - never pops up anything for me to enter the unlock code.
I'm running CM7, so I'm wondering if I actually have to flash my phone back to stock just to unlock the damn thing - sure hope not..hahaha
Any suggestions anyone?
Thanks!

[Q] Droid 2 Global

N00B here! but tried to gather as much info as I could..
Got a VZW droid 2 global from ebay that the seller profiled as "unlocked"
I'm in Central America and trying to register it with a GSM 850/1900 carrier but it won't connect to the network at all.
It had a 14 IMEI code... found it's translation to 15 to 17 IMEI and bought a the unlock code on a site. I got the unlock code but the phone has nowhere to enter it.
Found a post stating that it should ask for the code after inserting a foreign sim card or waiting 30 minutes if nothing happens. tried that and there's no prompt.
I have accessed the testing menu with *#*#4636#*#* and select the GSM only and WCDMA preferred (I got an HTC Inspire 4G working with that one here) and it is recognizing the GSM 850/1900 local carriers but unable to get any network access from them.
Found that VZW locks the carrier's network ids but the phone is recognizing them.
Again: ir recognizes the networks but is not asking for an unlock code... all the posts states to enter the code but they don't say how (the phone must prompt it automatically)
Please let me know if there is any way to manually pull up the field to enter the unlock code or if I can try anything else to unlock it
Thanks!
First, the phone's IMEI is written on the label under the battery.
Second, if you switch it to GSM mode it will output the IMEI in *#06# and in Settings, About phone, Status.
The 14 digit code you mentioned is probably MEID in hex form.
Switching to GSM is done by going to Settings, Wireless & networks, Mobile networks, Network Mode.
Using the service menu you mentioned is wrong and can lead to the phone being unable to connect to GSM at all, in which case you must reflash the SBF.
Actually I got the unlock code but there is nowhere to enter it.
Also it allowed to me to at least view the available networks after changing it to GSM/WCDMA and seems to be trying to connect to one but there's no signal at all.
If I do a network search now it will show me the available networks 5 or 6 (2G&3G), selected one and it just shows that it is not able to connect to that network
BTW, found that the radio was off as well and had to switch it on using the testing menu because by going to Settings, Wireless & networks, Mobile networks didn't allow me to access it at all, it was just grayed out and there was no way I could turn on the radio using that option..... sorry... I think I got everything I need except where to enter the unlock code
It looks like you have successfully (like other people before you) fried the GSM radio settings. Congratulations.
You need to flash the SBF to reset the phone's radio module to its original state.
If you actually bought a phone that was already unlocked it won't ask for an unlock code.
A locked phone asks for the code the moment you power it on and let it boot with a non-Verizon SIM card.
The code you supposedly bought is not for your phone at all, because you requested it for an IMEI you made yourself from something that was never an IMEI.
For me, The unlock screen appear only on original rom with non-verizon sim.
not appear on custom rom.

Phone wont SIM unlock

I've used the method described in the Sim Unlock thread to generate my code, but I can't get the unlock code request (dialogue box) to come up on the phone. I've turned it off and inserted a different SIM (it was originally O2, now it's GiffGaff, although I believe they use the O2 network) but I don't get the prompt to enter my unlock code. I can scan for networks and register on the O2 network, but I get No Service errors.
Tried a variety of ROMS. I got asked for the code on a Cyanogen one but it always refused it and asked for it at every boot. I've also SuperCID'd to 11111111.
Any clues?
Just reset phone to 1.78 stock and on first boot spotted a message "Restricted Access Changed". Does this mean anything?
So it would appear that putting a GiffGaff sim into an O2 locked phone won't trigger the unlock request. But putting a T-Mobile one in does. It's accepted the code, but I'm still getting 0 bars of reception.
Does anyone has any ideas?

SIM/RUIM is Perso locked - No service

I have looked into what this could mean, and finding that I have a pin on my sim but I dont
I can put my sim in my origonal device and works fine
this phone has been flashed with 2 roms both no signal only the 2nd rom was giving me this message at top of screen
one thing though, I am having to enter the sim unlock(phone lock from Three) code every time I reboot the phone, I obtained this code using the famous term emulater and running that specific string, this code enters fine and says
SSIM network unlock PIN, enters code, then gets - SIM Network unlock successful
any ideas
Forgot to add, if I go to settings, security, setup SIM/RUIM card lock
I click lock sim card and specify a code
Then tells me it cant because there already is one
I can choose Change SIM PIN, by entering the old one (12345? guess) then a new one
I have 1 attempt remaing before I have to contact my phone carrier
Phone is from 3 Mobile but my Sim is from O2, if I put this sim into my origonal device there is no PIN
Any ideas?

I would follow the other method on that guide and SIM unlock that way. It will be 100% successful and then you will know if your SIM card has a pin lock or if your device is having trouble. Remember that you need to be on gingerbread firmware to use the diag.nbh so search the forums and read up before you act

Galaxy S8+ not prompting for unlock code

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.

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.
