I have a tytn and I used the pof application to unlock the simlock?
For purposes I won't get into, I need to restore the simlock. It was originally with Rogers. I have already restore the ROM, not the radio, and have yet to downgrade the SPL/IPL but will do so after I am satisfied with the restoration.
Thanks
unless I missed something on pof's thread, once u sim unlock then it's always unlocked.
I actually don't see it posted anywhere if it is possible to reverse the sim unlock for warranty purposes...

Hello,
I'm trying to find a solution for my problem. I've searched the whole xda developers forum but I can't find an answer.
I've unlocked (and unlocked the CID) my T-Mobile MDA Vario with Lokiwiz, how can I put the CID lock back on my Vario. I need to send my phone in with a problem. Anyone who has an answer?
Thank you in advance.

I've read that cid restors automatically when you install backed-up rom with CIDlock, but I'm not sure when it comes to it and I'm also looking for sb who can prove it [;.
I've sent my phone to HTC for repair without doing anything to CID lock it. I did a hard reset though. I guess it locked itself up upon hardreset or the HTC people just don't borther if it is CID lock or not.
I am thinking about polish mobile operator - orange an its warranty and I know that he cares about cid lock.
Anyway, are you sure, that after hard-reset CIDlock comes back?
You can restore cid by restoring the lock_backup.bin file that was created during the unlock process.
to do that see here http://forum.xda-developers.com/vie...postorder=asc&highlight=cid+locking&start=400
look for britman's post.
Hard reset will not restore cid.
Thanks again ^^'.
sorry about the dumb question but why would one unlock CID?
Besides, the fact that I dont know what CID really is, I am not able to find the answer to the need/advantage of an unlocked CID.
If I purchase a SIM unlocked phone from any third party vendor (not form a Phone provide under a year's contract) I am able to flush the ROM (such as the GPS enable HTC ROM) as I like, correct?
So, why the need to unlock this CID? Is this procedure only necessary for phones sold through a provider or in order to flash with ROM releases from Dopod, O2 or any other then HTC directly?
Thanks for any explanation!
SIM unlocking is different from CID unlocking.
SIM unlocking lets you put a sim card from any phone company in.
CID unlocking lets you put any ROM on that you want because your phone is not looking for specific security codes to authenticate the ROM as official or genuine.
Just because the phone is SIM free, doesnt mean it's CID unlocked.
Actually CID unlocking only lets you install signed ROMs from other vendors than the one you originally bought your device from.
Des developed SSPL which allows you to do the same, and even flash unsigned (cooked) roms, you can also use CustomRUU which automatically pushes Des SSPL on your phone for you before flashing the ROM or use HardSPL (which is SSPL but flashed into the phone).
This means nowadays you can flash any ROM without the need to CID unlock your device, and retaining your original CID keeps the warranty, so there's no real need to CID unlock your Trinity anymore.

thank you very much for the explanation!
I am still not understanding everything (Des SSPL, HardSPL, etc) but apparently I am not really required to unlock CID, since I am planing on keeping the warranty alive and only use official HTC ROM's.
Thank you!
So i'm sending my wizard/mda back to t-mo for warranty and i need to relock it (i assume) i have all of the files from my unlock using lokiwiz, but i can't find a clear answer on how to relock it. i looked all over the forum, can anyone help? thanks.
--- I found a method,
http://forum.xda-developers.com/showthread.php?t=285253&highlight=relock
but it didn't work for me... anyone else have an idea? i found no lock function in a menu in lokiwiz as mentioned in the following post unfortunately.
If I remember correctly I saw the lock-function on the menue of the lokiwiz-tool when I used it to unlock ...
Drop it down to buttons 1.05 ROM. Using lokiwiz relock and then reflash it to T-Mobiles original ROM. That is what I recommend so far
I had my ex Charmer to send back to the factory (HTC Europe) to have the rear speaker fixed.. twice. I had the Charmer SIM unlocked and CID unlocked, it went through the warranty check without problems.
thanks guys. and i DID find the "lock" function in lokiwiz, i guess i was goin too fast.
It's my first post here. Done a lot of reading but still couldn't find the answer to this.
I got a sim locked T-Mobile Wing from T-Mobile. Still waiting for the unlock code. This could take a long time for my case. Should I wait until I get the code and unlock the Wing before flashing ROM??? I am very eager to play with the custom ROM's a lot of people are using.... If I do it now, will it cause problem later when I try to sim unlock???

What problem did you have? I thought if you do Sim Unlock first, there shoudn't be any problem. I am just worried about if I flash the phone first, the unlock code I will get from T-Mobile later might not work. Can anyone comment on this? Thanks.
i sim unlocked then flashed
the unlock code is stored in the phone operating system not on the sim card
but dont worry the phone will always recogize the unlock code every time u flash it. it never changes unless you hack your imei

So I don't have to unlock now and can go ahead to upgrade ROM and then unlock later with the new ROM? Just want to confirm. Thanks.

yes you can flash before sim unlock. I have a wing and its not sim unlocked and I can flash and go back to stock with no problems.

that doesn't make sense.. everytime you flash your flashing a new operating system. theres no way the sim unlock code is part of the operating system.
It Probably Makes More Sense To Me
Basically With The Unlock Code Your Unlocking The Phone Not The Sim Card So It Is Saved To The Phone When You Flash The Phone You Erase Everything On The Phone
This is exactly why I am reluctant to flash it now since I have not unlocked the phone yet.
I know that, with some other phones like motorola, even if you have unlocked the phone, but if you flash with a wrong stock, you can lock it again and it is very difficult to unlock later...
Can anybody else share their experiences about the Wing?
If you follow this thread
http://forum.xda-developers.com/showthread.php?t=358225 you can unlock your phone without worrying about the code from T-mo. You will be able to flash any ROM you choose. Just follow it to the letter. Worked great for me.
My main reason to flash was because of all the memory the stock ROM sucked. You'll be amazed by the chefs in the forum.

The unlock is not in the phone's operating system... its in the phone hardware. I think many will get confused if you are telling them its in the OS since you flash the OS when you flash the ROM.
Everyone should know that the IMEI is hardware based like the MAC address of the phone. To change the IMEI would not only break US law's but would void you from unlocking it from a service provider. Flashing a ROM will not change the IMEI.
I need to return my MT4G to HTC as it has a hardware problem. Hence I need to reset everything back to factory settings so that my warranty is not void. This means pre-root, pre-unlock, pre-modifications, etc.
Please can anyone tell me how to turn SIMLOCK on again? I had used the gfree method to remove it. And also how do you return the CID settings to its original? What are the original CID settings? I have searched but I don't see any thread on how to turn SIMLOCK on again so that it is locked to T-MO only.
Thank you much!
Please read the rooting thread in Development section.
It has unrooting procedure.
Search would have helped you.

Here is a link to the thread you need http://forum.xda-developers.com/showthread.php?t=858996 Procedure to revert is about half way down
Hi WOLF26915, prior to my posting, I had followed the procedures that you've listed on that link. Through a mix of flashing a stock ROM and using gfree, I can unroot, can turn S-ON but I am unable to lock the phone again through that listed procedure. I believe many posts deep in, others have said the same about that procedure that it unlocks, turns S-ON but it doesn't return the SIM lock back. My phone remains unlocked. The ./gfree -S command removes the SIM lock but there seems to be no equivalent command in gfree to return the SIM lock. Flashing of the stock ROM does not return SIM lock because it is located in another part of the phone. Sounds like there are specific commands to execute to return SIM lock. I just don't know what they are. I've looked hard. Seems like all the many procedures on the Web that I have found is about removing SIM lock, not returning it. I also want to return the phone back to its original CID but I don't know what the original CID is.
I am quite sure I did not make any errors in my following of the step by step instructions that have been listed on XDA.
Please help. Thank you so much.
There is a section in the guide, called:
Procedure to revert
Execute that section.
If you don't have a backup file part7backup-<numbers>.bin that is required - you won't be able to return SIM lock.
In addition, you're most likely wasting time - nobody is going to check the CID. Return the stock bootloader with S-ON, and it'll be more than enough.

I sent mine back with s-on but with the custom cid and Sim unlock. They only check for the problem. You should be fine as long as it appears stock
Sent from... It doesn't matter!
