xda exec blocked

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 ?

How can I enter my sim unlock code?

I'd like to try out a sim unlock code I generated for my 8525. However, I only have the one sim. How can I get to the unlock process without having to insert another sim? Really I just need to test it.

I'm not really sure what you're asking.

Huh?

I'm not really sure what you're asking. Why not ask the person whose sim card it is for the unlock code? If you are just "testing" the phone at this point, I'm assuming it's not even your phone.
If you want to see a Hermes in action, go ahead and return it to the rightful owner and I'm sure they will give you a friendly walkthrough.

Doom Tints' Score: ZERO for reading comprehension.
I have an 8525 that belongs to me. Shall i forward you a receipt? Very helpful. Anyways, to clarify for anyone else who gets confused easily, I was curious how to I can test my sim unlock code on my own locked Hermes. Obviously I could remove the sim lock with the stickied utility in the forums, but that is not my purpose. I simply need to verify that my unlock code generating algorithm is working. I don't believe that I've seen anyone discussing the ability to generate unlock codes for any arbitrary IMEI before. Although I could be mistaken.
The wiki states that I can use:
[email protected]=0,<facility>,<code>
Facility is a number between 0 and 32, code is a 8 digit code.
What shall I use for the facility? "SC"? "PS"? Those are the only relevant facility codes I know of. Should then I convert SC to 0x5343? Maybe I just answered my own question...
Thanks Doom Tint!

I'm not sure there's a way. I just ended up borrowing a friend's T-Mobile sim when i was unlocking my 3125 - it takes about 2 minutes so it's not big deal to do quickly then hand back the sim chip to the friend.

Thanks for the clarification instead of the tiny 1-sentence question without explaining what you were doing.
BTW, I had already edited my message before you posted your response.

woohoo!
yay! it works.

anyone know if there are any HTC models which cannot be sim unlocked through published means? this unlock code generator should be universal,

This only works on devices with qualcomm msm6250 (universal) / msm6275 (hermes, trinity...). It needs a bootloader with 'rtask' command but you can also do it in a simple CE program with RilDevSpecific() functions, communicating with the radio through RIL dll if you don't have an 'rtask' enabled bootloader.

[POLL] Did you subsidy unlock (sim unlock) your G2?

IMPORTANT NOTE: Before choosing option 2 or 4 (G2 CAN NOT register to networks), open Settings > Wireless > Mobile Networks and attempt scanning for networks. If any networks appear in the list, pick option 1 or 3 regardless of whether you have voice/data access. Also, you may wish to try multiple sims, including the T-mo us sim included with the G2 package.
If you entered a subsidy unlock code in your T-Mo G2, please choose one of the poll options above. The purpose of this thread is to determine whether the source of the subsidy unlock code has any correlation with recent reports of G2s being rendered unable to register/see networks. Please see/reply to further discussion in the thread here:
http://forum.xda-developers.com/showthread.php?t=805024
Please only reply in this thread if you chose option "Other (specify in reply)". General discussion about this issue should be posted to the thread linked above.

My code is from unlock-now.com and I got the same code from freeyourhtc.com
I can not search for or connect to any network (as you probably all know by now)
(and sorry I did not read properly that I should only post if I select "Other")

It's fine, i'm just tryin to keep all the discussion in the other thread so we don't end up splitting the topic.
Results look inconclusive so far. Looks like we might be hunting down this radio problem for a while.

this poll should be Pin on top, otherwise will be down to 2-3 pages and ignore

I am very interested to see the results of this. I'm currently in Japan and waiting on the unlock code.

Stuck
Is there any resolution to this problem? I bought an unlocking code from
Free Your Htc Unlock Code Server <[email protected]>
I entered the code, it confirmed unlocked and rebooted. Now can't see any network with the original T-mobile SIM or local network. Want to use this unlocked phone here in Brazil.
Called HTC support, they say talk to T-mobile. Am I stuck?

I certainly hope your not the last haha

If you need a code for your G2. PM me.
I can help you.

I got a code from TMO and i tried to use it but the code would not work. I figured it was becasue i got it for one G2 and use it for another G2.
Was going to wait until im settled on a good G2 before i asked for another unlock code but from what im reading it sounds like these codes will work on any phone.
Is that correct??
Sent from my T-Mobile G2 using XDA App

Code is unique to each IMEI. If you give T-mo the IMEI for G2 #1, it will only work for G2 #1. Entering it in G2 #2 will be pointless and possibly even dangerous if you attempt to enter the incorrect code too many times.

No luck
Got code from third party unlocking solution. Entered the code. Successful unlock message, reboot.
Now NO SERVICE. can not search for and register for any network.

Thanks that's what I figured.
So these other unlock codes must be a different type of code?

Other
I have an unlock code from T-Mobile (that matches my IMEI).
When I entered it, I got "unlock PIN: Unlock success, reboot immediately!! OK"
I pressed "OK" but the phone seemed to hang at that point. (The OK button stayed highlighted.)
After a minute I pulled the battery and rebooted. When it came back up (with foreign SIM still inserted) I got the "Enter unlock code" message. I didn't want to try again due to T-Mobile's warning that there are a limited number of attempts until the phone is permanently locked. (T-Mobile later told me the number was 3.)
After this, I put the T-Mobile SIM back in and it worked fine.
I called T-Mobile and after talking to four customer service reps, they finally found a memo describing this as an active problem and that they were working on it. I won't try again until I hear from them (or I get a software update.)

Network sim unlock pin tmousa?

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.

[Q] HTC HD2 unlock problem

I am looking at purchasing a HTC HD2 from ebay. Unfortunately, it was from a "batch of phones that had left the suppliers locked" The supplier eventually offered a refund and he also, maybe inadvertently kept the phone as well. When he now puts in the SIM card the message reads --"Service provider is locked. Please input unlock code." Apparently you can have these unlocked, but one site states that "This service will NOT remove your phone’s security lock" Can somebody please explain to me what this means? Is it correct that you can only enter the unlock code 5 times and then it is permanently locked? Is there any way round this? It seems a little strange that the phone provider supplied a locked phone, then provided the unlock code, which for some reason didn't work? I would appreciate any advice. The emei number appears to check out as far as it is not blocked. I will pay for an "official" check, if it appears that I can get round the unlock problem. I could always approach the original supplier and request an unlock code, and hope that their unlock procedure works the second time round?
Thanks

Which carrier is this from?
Usually when you enter it wrong x number of times you now have to enter the "unfreeze" code, which you should be able to get from the phone provider. Most online unlocks also have the unfreeze code.

What country & network was it locked to ?
Most can be easily unlocked via codes matched to the IMEI
*Do make sure IMEI on sticker in battery area matches that of actual mainboard IMEI when you dial *#06# to view IMEI on screen
Have entered more than 5 myself & been on a time out wait for quite some time ...
Security lock is to do with firmware certificate checking & nothing to do with SIM lock ...
I get all my codes from http://www.pdamagician.com/unlocking.html but if you tried some code already without success I would ask them if they have another code not matching what already been tried.
Other option is getting it unlocked via cable & software & this method can unlock SIM, CID & Security as required but you need to find a local shop that supports it ...
Also worth noting you need to be on Windows Mobile ROM to fully support the code unlocking.

Thanks for the replies
Supplier was Virgin UK
Just to clarify:
"Service provider is locked. Please input unlock code."
​• This is security lock and can be unlocked by using:
​o code from original phone supplier (Different one in this case).
​o code from 3rd party online supplier such as pdamagician.
​o cable connection using specialist software at local shop.
IMEI sticker number matches mainboard
• This can only be checked after unlocking security on phone as above?
I presume by windows mobile rom, you mean not running on other operating system such as android? The phone has never been used, so it will be on windows and therefore not be a problem?
Are these phones still available new anywhere?

I can still buy them new here in Bangkok but getting harder to find.
Vodafone UK should be easily SIM unlocked by genuine HTC code & if for some odd reason not software & cable will for sure.
I would get likes of pdamagician to verify the code you have already tried as suspect a genuine HTC IMEI database code will be different .
