I heard that was released some IMEI generator with which you can unlock your phone on any network. As it has for Nokia phones.
Does anyone have experience with those related to LG GT540?
If there would be useful to put on the net.
Dont know if this is true , but somewhere i heard that not many android phones are actually locked to a network, they just have branding on them , and may have system apps.
But i havnt tried it out as everyone in my area is on the same network.
Well, I know it's a little phone is locked, but all of them will be more. Actually here is the word that if anyone knows and help those who have locked phones to network operators that have purchased the machine do the opposite. More specifically, to unlock and simply use any sim card.
Most Android phones are locked only at the software level. This is true for GT540 as well I guess. It's not usually locked but when it's locked, it's just software lock. Not an IMEI lock. You just have to root it and unlock the phone. Or, flash an unlocked KDZ.
IMEI locks are not used on phones generally. They are used only one stolen phones.
On the other hand, in some networks where SIM cards are not used, the phone is authenticated into network using IMEI/IMSI/MIN/ESN. When this is done, you don't need an IMEI generator, you will need the IMEI/IMSI/MIN/ESN of the phone/SIM tied to your account.

if i change the rom to an i-mate jasjar or any other will it be unblocked?
No
why is that ?
I'm not an expert but Sometimes I wonder why is that, If we replace ech and every file of locked mda-pro with unlocked jasjar ?? then there should be no reason for a locked mda-pro.
can anyone explain inside science of locking & unlocking ?
I think it also depends on the definition of "blocked"
If the phone iteslf has had its IMEI blocked, then no amount of reprogramming/reflashing will unblock it.
If the phone has a simlock on it, then I believe this would be to do with something within the phone hardware itself.
Hi guys
That old chestnut again, locked and blocked are 2 completely different issues and unfortunately neither of these actually involves anything that is didrectly under the control of pocket windows.
There are 2 types of locking.
1) PUK locking (SIM Locking), this occurs if you incorrectly enter the SIM pin code 3 times in a row. If this happens you need to contact the network provider to get PUK unlock code, better still if you enter the PUK code incorrectly 5 times you will destroy the sim and need t get a new one.
2) Network Locking is a flag that specifies the LAIN of the mobile network that supplied the mobile phone and if this feature is enabled by the operator it will mean that only a SIM card that has the corect LAIN will work in that phone. I forget what LAIN stands for but basically it is used in the GSM international roaming world and therefore each operator has its own, the first few digits indciate the country then the last ones the specific network.
This can be disabled in 2 ways firstly by using and encrypted code specifically issued for your handset. Or secondly by trial and error by writing different values to the registers on the EPROM on the GSM unit itself. Eventually this will result in the phone unlocking itself. In order to do this the gsm engine needs to be removed from the handest and interfaced to a serial port. A 0 or a 1 is then sent to each register 1 ata time and the phone is then tested to see if it works. Depending on the size of the chip this takes a long time. However when you no the memeory location of the register this can then be done to any phone in a matter of minutes. this is basically the way modsyt of the unlocking systems are developed.
Finally IMEI blocking. This is done where the network has evidence that a crime has taken place either fraud commited on the handest, abusive phone calls or the unit has been stolen. If the network IMEI blocks it you have 2 options, 1 sell it in a diferent country ( Nigeria) or some chip sets contain the IMEI details on a flash chip. Again the registers are read over a serial interface and this can be rewritten. The first phones to support this IMEI in flash were the siemens TC35 gsm engines also the wavecom gsm modules support this. I am not really sure of any legitimate application for changing the IMEI of a mobile handest or even why this data is not writen in ROM but there you go.
I hope that helps to clear up issues relating to locking and blocking.

thanks for such informative essay, we all are concerned about the network locking. I have noticed a tool to remove simlock from HTC wizard using same OS as HTC Universal. but in the above post its mentioned that OS has nothing to do with unlocking ..
But unloking tool of all old HTC devices running WM 2003 never took so long as in the case of Universal ? or may be quite possible that all good brains of our forum dont use Universal ?
Hey guys, strange problem:
Got a Telus LG Optimus 7. Want to unlock it to Rogers. Got the unlock code, however when I use my Rogers SIM the Optimus asks for a 'PUK' number.
Long story short, I called Rogers, they gave me the PUK for my SIM. When I enter it I get 'SIM Error'. So I went to a Rogers store and got a new SIM card with a new PUK--same error. Tried someone else's Roger's SIM--still asks for PUK.
I called around, no one has any idea what's going on. Google can barely help. Telus tells me I have to pay $50 to get it off their network, but I can't trust the rep knew what the problem was and they won't just give me an unlock code I already have. A 'cell phone repair shop' tells me LG phones are impossible to unlock anyway (? really?). So my question is:
How do I unlock this phone? What kind of security is this (could the PUK refer to someother other than a SIM's PUK)? Anyone have experience unlocking a Telus Optimus? Can I flash this thing and see if it'll bypass the PUK part?
Any help would be deeply appreciated. Other wise I have to try and resell this phone.
So, I re-flashed the phone anyway, just to see if it works.
Now it's a little different. Now it asks for a PUK and once I enter that it tells me to create a PIN. When I do it says SIM ERROR! So while I can get a little farther it still errors out!
I've tried both the Telus flash and the Mexico flash.
So if it's not the firmware, what could be causing this?!
PIN & PUK security depends on SIM card functionality, in this case phone software is transparent and does not verify PIN. IMHO it looks like incompatibility between SIM card and WP7 phone or strange configured SIM card. Try on another non-WP7 phone, maybe if you set or disable PIN code card will function on WP7 phone.
Thanks for the tip elektryk. I think you're on to something.
I have tried the SIM in a non-WP7 phone. It works fine. I put it in both an iPhone and BB. Using the iPhone I created a PIN then tried the Optimus. It now asks for a SIM pin--which I input, then goes back to the PUK screen which still fails.
It seems to be a very strange incompatibility with the SIM, even though I've read reports of Telus Optimus being unlocked for Rogers SIMs.
Bad luck I suppose?
I have exactly the same problem. I put a SIM with PIN security enabled, and after I enter the correct PIN requests the PUK!! and if I disable the PIN secure, request inmediatly for the PUK. The Phone say: Your phone is Blocked. Contact the Service provider for an unlock code.--- the only problem is that I don't use the AT&T service, so I can't contact them!! HELP!!!!!!!!!!
Fabian, I could not find a way around the problem so I sold the phone. Luckily there was another e900h which was unlocked for sale. The guy followed the same steps I did but it never asked for a PUK. Weird how some phones do and others don't (especially considering both phones were from the same provider).
EDIT: Hey, try this, see if it works: Try without sim card for enter the unlock code. and type 2945#*900# for enter the unlock menu

Hey, start the phone without sim card, but no unlock code required, no where to type.
I've a E900h where none of the 5 unlock codes provided worked for some reason. Haven't ask for PUK yet but lost as to what to do right now.
Typing 2945#*900# just produces a failed msg - top left hand corner is a file icon with lock on the left.
In our country ones you buy a sim from network provider.
they give us a card with a PUK code for the sim we buy.
Try to contact your service provider.
Unlock codes is For unlocking SIm Only.
you can switch different SIM f u have unlock codes.
it is different with SIm Pin Code.
You can get Ur PUK Code to your service Provider.
what country were u from??
PRESS THANKS IF I HELP!!
I work as a repair tech for a used cell phone company. I recently had this quantum come across my desk to be unlocked. OK, no biggie, I order up the unlock code, It comes in, I put my store sim (incorrect sim, non at&t) in to get the unlock screen to pop up, Instead, I get a puk code error. Now I know for a fact that my store sim does NOT have a puk lock on it, I took it out and put it in 5 other unlocked phones on my desk, and it worked fine in each of them. Is there some sort of glitch with the quantum that causes this that anyone knows about. Maybe something in the software corrupted? I cant unlock the phone, If I cant get past this PUK crap. Thanks.
EDIT: I "have" done both a hard reset using key combinations on start up, as well as a full phone reset through the menus, didnt help.
just tried a few t-mobile sim cards as well as a couple other non-at&t providers, it asks for puk code regardless of the sim as long as its not at&t.
Sounds like someone's done something weird to that phone. My Quantum unlocked from AT&T with no problems at all.
You need to call the company the cell phone is from (at&t) to get the puk code, I have heard about this before

Unfortunately, when we buy used phones from people, they rarely have the sim in them. I'm pretty sure you have to have the sim that the original PUK code was attached to, to get the code from AT&T. Guess we'll just have to resell this one as AT&T only...
I have the PUK code and nothing happens. Is asking me to the PUK code again and again.
The phone is locked to the ATT, think so or something weird that nobody knows, cause is impossible to fix.
seems like an LG issue, i'm having the same issue with an LG E900 Optimus 7.

And, what do you do Adam?
In my case, the Rebel Sim doesn't work.
it's been permanently locked to at&t ( if you have bought it from them) or whatever ..... because of too many (usually 5) wrong unlock attempts . you can't unlock the device using unlock code . you gona need some software to unlock it through usb cable
I'm having a dispute with tmousa regarding them locking my phone to their network. I own my phone but put one of their prepaid sim cards in my phone. I guess they thought it was one of their phones and they locked my imei number to their network. Now for over a month I have been trying to get them to provide me with the network sim unlock pin so I can take my phone to another network but they're saying my phone has been modified and they can't find my imei number in their database so my phone is basically a brick now. They claimed they contacted HTC to get the number with no luck. Is there anything that I can possibly do now? Thanks.

IMO you should contact one of the ebay's unlockers and check if your IMEI is unlockable(it is cheap to unlock, about 2-5US$).

Did you give them imei number shown in the phone software (not the back)?
Wow thanks for the eBay tip! Just paid for the code so waiting for it now... I thought this was a different type of lock. I thought the Rom itself (tbd sense) unlocked the phone to other networks but I tried a wipe and re-flash and it was still locked so I should have asked the question sooner. Will post the result.

Also just so you know it was not the sim card you put in it that placed a lock on the device to just use T-Mobile. The lock was on the device from factory, all US cellular providers do this to all devices they sell. It is a effort by the providers to keep you from changing providers so easily. They figure if you have to buy another device to change providers you would not be so willing to change to another provider because it will hit you in the pocket book harder. It is a very under handed practice in my opinion and should not be illegal. We pay for ower devices and should be able to use them how we want and with what ever provider we want. But then again we live in the worlds greatest country right.......what a joke.
I have had an HD2 since they first arrived at T-Mobile. As stated, all phones in the US are carrier locked by default.
It was easy for me to have mine unlocked. I called T-Mobile and told them I would be traveling out of the country. I asked for the unlock, gave them my IMEI, and serial (maybe). That was all it took. I got a text message with the code.
Hi XDA,
I was wondering if there is a way to unlock/openline both sim card slot in other networks.
My Samsung s8 is lock in Smart carrier network here in Philippines.
I am aware of the flashing but i not a tech guy so I might need step by step procedure and the resources needed to do so because i do not know which firmware to use and to be sure not to kill my phone. Hehe
I searched for openline precedures for SM-G950FD variant here but no luck what i found are for other variants.
Hope you can help me.
Thanks in advance!
Have you tried contacting your network carrier to do the unlocking for you?
As a side note, I don't recommend trying to unlock this phone via unlocking codes as Dual SIM devices are usually problematic when it comes to this sort of unlocking.

Sorry but I dont not recall that there are such services offered in our network carriers here, thats why people like me we seek help in forums and service shop that dont have 100% asurance of good result.
Thats to bad, so i will be unable to use the 2nd sim card slot anymore but can still use it as memory card slot? Anyways thats fine with me because 2nd sim card slot is also locked in the same carrier.
I dont know the point of locking both sim card slot, what would i even do with the 2 sim card with the same network? Hahahaha
up on this one. thanks
Networks lock the whole device, so they don't care if the device at hand is a single or dual SIM.
However, this becomes an issue only when trying to unlock the phone by unlocking codes. But, bear in mind that you could still unlock the phone but by other means. You could try an unlock via USB in your local phone repair shop.
You have to try.
Also, can you let me know where are you trying to use this phone (with what SIM card)?

Alright! I should just unlock it as a whole.
Is there a way i could just do it myself, i dont really trust those repair shop because of bad experience.
I am new to this unlock thing but i rooted several phones way back and flash in odin, so i think i might able do it.
The phone is Smart Communications locked an i also want to use it in Globe Telecoms.
Check other forum threads, I am sure you will find information on how to do it yourself.
Smart said that the 2nd sim slot is open to all networks as long as you have sim 1 as smart or sun. I emailed their support. So it may be trustworthy. Have you tried yet?
how did you resolve this problem sir? i have the same scenario but the difference is my phone is globe locked and i want it unlocked to use smart i have the code for unlocking the sim and when i did unlocked it i can use different sims now but the problem is i cannot use the data. it is greyed out. any inputs?
