Will new ROM require SimLock Code to be entered again - G1 General

I've recently bought an unlocked G1 from eBay. It's works with a Vodafone Sim I have, so the Unlock code has already been put in, but the seller didn't provide the code to me.
My question is, if I root the phone, install a new SPL, Radio and, say, Cyanogen's ROM, would it require me to enter the unlock code again?
Or, is the fact the phone is unlocked stored forever?
This is a UK G1 btw

no, unlocked forever

Noob new Blackstone - Unlocking clarification

Guys
I've searched the forums and realise I can buy a SIM unlock code for my Blackstone, however I'm trying to clarify the following.
1. If I install a different ROM do I still need to buy the unlock?
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
Thanks in advance for the help.
Regards
Its an unlocked phone my friend so obviously you pay a higher price for the phone itself able to use with any sim card. Carriers phone that are branded with the carrier logo are usually cheaper with a plan that could cost more then the phone overtime and is locked to the phone carrier which requires a sim unlocking code to use with other sim cards/ other carriers.
The answer to that is you can install any rom on the phone and if it an unlocked htc touch hd which you paid a lot for then it will be unlocked forever
if its locked to a carrier im not sure about that maybe someone can clarify.
any ideas please guys, I get the phone in a couple of hours.

Anyone?
Try to keep this short
1. If I install a different ROM do I still need to buy the unlock?
No Simlock is based on the radio and hardware (short version).
Once unlocked yoiu can up your rom and your radio, it stays unlocked.
2. If I changed the EMEI (I want the phone to match my in car fixed EMEI - I realise the blackstone has to be switched off when in the car else conflicts) does that mean the phone has to be unlocked again?
Got me lost on this one.
Simlock is based on radio and Hardware.
So your IMEI is part of the phone which is either Sim Locked or not.
If you put your sim into what ever is in phone is in your car your number will be the same.
Once you have sim unlocked a device it remains unlocked.
Like I said you lost me.
3. Once the phone has been unlocked if I change the ROM will it have to be unlocked again?
No - Once done it remains unlocked regardless of rom or radio upgrade.
(and if you buy a new Simlocked Blackstrone you cant use your old code as the lock is based on the hardware)
What prompted the question is reading the Wiki few areas actually simlock the phones....therefore my assumption is a different ROM means it could become unlocked.
--->point me to the page that you feel needs updated, i will have a go at it.

I can find the simlock part but how can you use it to unlock the mobile ? It looks like a key file is needed.
worked htccode.com for me also
I have purchased a code from this site also but it's not working, when I put in my o2 sim it asks for the unlock code but then gets stuck on a screen saying "unlocking sim"
what rom are you flashing?
ive got the htc .exe one which I flashed after creating a gold card & updating via my pc.
Did you update from the memory card? if so can you provide a link to the rom you used.
Tried a few sims now & the APN options are greyed out, so there must still be some orange stuff stuck on there.
It is fully recommended to flash before trying to unlock
follow the instructions to flash: http://forum.xda-developers.com/showthread.php?t=603286
I bought the code from HTCCODE.COM and got UNKNOWN UNLOCK CODE
I flashed rom from this tutorial http://forum.xda-developers.com/showthread.php?t=603286
and tryed again but same problem code doesnt work...
This tutorial works fine. You should contact htccode and ask for help there.
I followed the tutorial but even after changing the rom the phone doesn't accept the unlock code.
For those who said it worked, was your phone locked to Orange UK??
Mine is locked to orange uk, and I cant remove the sim lock even if I flashed and entered a correct code. I got a refund for my code not working.

System Updates Questions

I just purchased a unlocked my touch 3g ( I believe Magic) no slide.
At times my phone asks me to do a update.
When I look at what the update is it shows "Android System Update 1.2...The system is required to install Android version 2.2.1 on your device."
My phone states my firmware version is 1.6
So my questions are:
Do I need to perform this update?
Will this update lock my phone again ?
This is my 1st android phone and truthfully I'm not real technical. I have been going around googling different thing to make mysel more familar with the phone and Android.
Any help woul sure be appreciated.
Thanks in advance
Ok so 81 views and nobody knows.
Anybody have any idea what other sites out there may deal with this type of thing that they may be able to direct me to?
Thanks
Could you please provide the info on your fastboot? You can get to fastboot by turning the phone off, then turning it on while holding down the volume down button.

I hope this helps and what you were asking for
Thanks
First off, you do not need to update if you don't want to. Second, I think the update will relock the phone, so I recommend not updating at all, unless you have a reliable method of unlocking again.

I appreciate the info
Ok there are two things:
1) Sim Lock.. if your phone is sim unlocked it will remain sim unlocked.. actually I don't think there is any documented way to re-sim lock the phone.
2) Root.. if your phone is rooted i recommend installing a rooted version of the upgrade if you desire to upgrade.. otherwise the upgrade will either unroot the phone or fail because the phone is currently rooted (possibly causing it not to boot into android until you restore a good firmware)
Remember the sim lock is different from root.. and you can be rooted but sim-locked... or sim-unlocked but not rooted.. the simlock is just the tie in to the carrier and part of the Radio.. not part of the android firmware. Further its in a special radio settings region that is not flashed when you change the phone's radio.
So if you have the stock un-rooted/un-modified firmware and wish to update feel free.. just note you may want to back up what you can first.. some people have had problems with the update going slow until they factory reset after the update..
ezterry,
Thanks for the info.
Truthfully I'm unsure about many things on this phone.
I purchased this phone off Ebay as a unlocked only phone.
When I received the phone I just popped in my sim-set up the phone and was done.
At this point though I'm not even sure its unlocked because it is a T=Mobile phone and my service is myfamily mobile,which is just T-Mobile sold at Walmart.
I put in a sim card from my neighbors AT &T and it asked me for a pin #.
I skipped putting in a pin and the phone opened up but said no service. With that I am just assuming it is truly unlocked.
Am I correct?
Um.. if it asked for an unlock code its locked.. if it was sold unlocked and showing the code you ought to have been provided the code by the seller.
Pin usually just means the owner of the sim locked put a pin on the sim to prevent it from its data/service being accessed by others. (The sims owner ought to know the pin) This pin needs to be entered into any phone the sim is put in.
As soon as I find another person with a different sim card I am going to try it again.
I do think it was a pin # that was asked.
Unfortunately the owner did not provide any sort of code when I purchased.
Its my understanding,and I may be wrong,that you can purchase unlocked phones new,and if so I'm not sure weather or not codes are provided for new phones.
This is all very new to me so I am not sure.

If a HTC Dream/Sapphire was sim locked at the factory you must put in a sim card from another carrier and unlock the phone.. If it was never locked (such as the Google versions of the phones) this is not needed.
Once Sim Unlocked it will remain so regardless.
Yes, this is a My touch 3g google version phone

MT3G = T-Mobile = locked to T-Mobile US but running the Google firmware
ION = Google Development Phone = factory sim unlocked

So does this mean the phone is not unlocked and can only be used on T-Mobile?
or
Is it possible someone paid a 3rd party for a code to un-lock it?
I guess I really need to try like a AAT & T sim and see if I could service,as that was my undrstanding. I was under the impression that any gsm service provider uising a sim card would be operable.
You have gone in a circle now.. I told you if its sim locked when you put in a sim of a diffrent provider it will ask for an unlock code.. once sim unlocked it will *never* be locked again.
You will of course need a non tmo-us sim to be sure.
All I know is the MT3G will have been shipped from the factory locked.. I will not know the current state since the seller prob made sure it was unlocked if it wasn't already so if the phone was sold unlocked ..
The only other way I know to test is harder to do and possible risky with the firmware changes to do it w/o special htc serial wires.
And FYI a pin protected sim will ask for the sims pin before the sims carrier can be read (thus you need to provide the sims pin before it will ask for the unlock code if the phone is sim locked)
Ok,gotcha.
Sorry,told you not to savy
So I'll test another sim again and see what happens.
Thanks again for all the support

Ok.
So I pulled the sim card from my neighbors AT &T phone and when the phone booted up it asked me for :
"sim network unlock pin"
unlock
dismiss
My neighbor told me he didn't have a sim pin,but he used the code he has to lock his phone.
I received the same message when I tried someone elses sim who also states they have no pin number.
Message being: "Network Unlock Request Un succussful"
So am I correct in my thinking that this phone is not unlocked? and or it is sim locked?
I just e-mailed the seller asking him if he had the unlock code for the phone,so I can now only wait for his response. In the past he was not very responsive to past e-mails

Samsung Focus Carrier/Sim Unlock Question

I have an 1.3 rev Samsung Focus. It was an unlocked model I got from outside. I was in the US at the time of Mango update and updated my phone with Mango from AT&T. Now I have moved out of the US and want to unlock it. AT&T doesn't have the unlock code because I didnt purchase it from them. Any Ideas on what I can do? Will a custom ROM help me with Unlock? When I check lock status, it is SIM Lock is Disabled, only Network lock is enabled.
I'm not sure what you meant by "It was an unlocked model" in the context of "out of the US and want to unlock it". Was it unlocked or locked? Anyway:
Read the wiki, (carrier) locks are in NVRAM, no relation to flashing whatsoever, so any custom ROM won't SIM unlock your phone.
Have you tried ebay? Unlock is cheap as $1 and it doesn't hurt to try (unlock via IMEI - I unlocked AT&T and Rogers Focuses). If that fails, I recommend fastgsm, I've unlocked my own AT&T Focus with them, via USB (no affiliation).

It was carrier unlocked, as in I could place any sim in the phone and it would work. After I updated it on my Zune with Mango, it was loaded with AT&T's version and hence locked to AT&T. Now AT&T doesn't have the record of the IMEI in their database and aren't able to provide me with an unlock code. They were able to provide the unlock code for my other windows phone that I purchased from AT&T. Thereby lies my predicament. Let me try the ebay version, if not I hope FastGSM works. Thanks.
I was not able to get the unlock code from ebay. But FastGSM seemed to work wonders. I used their USB unlocking tool and it worked just fine. Thanks for the tip.

[Q] Carrier lock and CM7

I'm about to change carrier and my phone is currently simlocked. I have the unlock code but would like to know if CM7.2 will ask for the unlock code at boot with my new SIM card like it is described on my old carrier procedure, or if I need to flash my carrier's SBF to unlock the phone.
