[Q] Locked HD2 - Android Q&A, Help & Troubleshooting

My friend here at work has the same phone as I do the HD2 and he uses a password on it and somehow he locked his phone and can't get into it anymore. Is there any way to unlock the HD2 without hard reset?

Will Upgrading the ROM re-lock a phone I had unlocked?

When you unlock the phone, what gets unlocked ? The phone or your sim card ? Here is my real problem:
I originally had the XDA 1 from T-Mobile, bought an XDAII on Ebay, was told it was unlocked, but it was not. Ran the xda2unlock program from your website, it unlocked the phone so I could use the phone itself with my old SIM card from T-Mobile. Now I see there is a new ROM from O2, the question is, if I run that, will the unit be locked once again, and since the Radio verison on the new ROM is 1.17, and the xda2unlock only works on 1.10 radio stack (as said on the download site here) will I then be stuck with a phone with a new ROM that is once again locked - that I won't be able to unlock ? I don't want to try this unless I am fairly certain it is a safe thing to do... :? :? :?
it wont re-lock the phone if you upgrade
When you unlock the phone, what gets unlocked?
Where is the information stored that determines if a phone is unlocked or locked then ? If it's on the SIM card itself, then I could see that a phone upgrade wouldn't (shouldn't) have any effect. If it's on the phone, wouldn't that lock/unlock information be overwritten when the phone's ROM is upgraded? :?
re-locked
Nope, I unlocked my XDAII then upgraded the ROM to the latest and nope it didn't relock it stayed unlocked!

It's not on the sim card
lock information is found in the bootloader of the device, so it wil be not affected due a normal firmware upgrade
so if I replace the boot loader of the device then will it unlock the locked phone.

[Q] Problems with SIM Unlock

Hey Guys,
Hopefully someone can help me out since I can't seem to find answers anywhere to my problem. I got an unlock code from T-Mobile but when I put a foreign sim into the phone is says "invalid sim, 0 attempts remain". I got the phone on craigslist so I'm guessing whoever had it before me tried unlocking it with the wrong code too many times. I have the right code now, how do I reset the attempts? I can't believe that the phone is hard locked and there isn't anything I can do about it. It's pretty frustrating so any help would be appreciated!
Thanks!!!
really???? no one knows anything about this issue?
So people here know how to put different operating systems on phones but no one knows if it is possible to reset the sim unlock counter?????
the phone is hard locked and (certainly in most cases) can now only be unlocked by using a hardware unlocker. (for most phones, you get three attempts via the keypad, and a further 10 via a hardware connection normally.)
thanks for the reply! what exactly does hardware unlocking mean? would i still need to use the code given to me by t-mobile?
speak to a phone shop (or better yet speak to t mobile first)
have you tried to restore the phone to factory(not a hard reset). I would try going to Tmobiles website and try to update the rom...

^is for US phones I just did mine today because the guy that put android on it removed the unlock screen and I was unable to unlock the phone. And no one on here was able to answer any questions for me so don't feel bad.
Got it unlocked last night! turns out the sim card i was using was locked. i tried a different one and it let me key in the code. thanks for all the help!
now that the phone is unlocked would doing a hard reset lock it back up?

Click to expand...
Click to collapse
good stuff. No, flashing / hard resets will not ever lock the phone now.

[Q] Does having SPL and a flashed rom (miri's rom) mean my phone is unlocked aswell?

Just wondering if this means that my HD2 is unlocked. Also, is there anyway to check to see if it is without trying another sim card? Thanks
SPL & a Custom ROM will not SIM unlock your phone...if you bought the phone from from the carrier call them to get the unlock code or buy one online if you need SIM unlock.

[Q] Unlocking bootloader on network unlocked phone

Hi all. Im about to order this phone on ebay and just have one final question. I am unaware if wether this phone was factory unlocked or unlocked from a network. I know on some phones (xperia) if they were network locked at any stage you cannot unlock the bootloader, is this the case with the HOX+?
So basically I want to know is there a possibility that I wont be allowed unlock the bootloader of this phone and be stuck on stock rom forever?
