[Q] G1 SIM unlocking - G1 Q&A, Help & Troubleshooting

I have my old G1 sitting around having no use since I have had my Desire HD for a while now. I want to give my G1 to a friend that recently busted his phone. My G1 is rooted and running a custom ROM and I can comfirm as of this very instance I have su access in Terminal Emulator right now. So whats the issue?
My friend is on O2's network and obviously the G1 is stuck on T-Mobile, I believe I was told that when you root an Android phone it becomes unlocked but when we put his SIM in it asks for the unlock code.
I dont fancy paying for an unlock code since I'm giving the phone away. My Desire HD which is rooted excepts his O2 SIM despite being locked to T-Mobile due to it being rooted etc. So why wont my G1? What methods should I undertake to fix this?

I take it the lack of response means I'm buggered and I cant do it without like throwing my phone at a wall?

I think the lack of responses is because these phones are so old there isnt much traffic on this forum. I wish I could help you but I cant get my recently aquirred G1 to function past the signup screen. I am just chatting with myself on the thread I started.

Shame, I figured the G1 is pretty much dead, I have been using my Desire HD for so long, the support on the forum is great for it, I wish for the same with the ol' G1 but it ain't so.

I unlocked my subsidy lock today. Just call tmo and ask for the unlock code. The phone is so old now that they shouldn't hassle you. It did take a day for them to reply but they did it.
sent from XDA app using darky 9.5

i bought an unlock key off ebay for 6.2$

i've recently bought my G1 on amazon.seller mistakly snet the sim locked version.
so i started to research and found that ther is a good idea FREE o obtain unlock code.it is said that T-mobile gives you unlock PIN code for free if you've been active account for at least 90 days.so contact them and they'll give you the code

T-Mobile G1 Unlock

Heya all, well i just menage to finally buy a new g1 off ebay been trying for awhile now but finally got one for the right price but the thing is.. being new its locked to t-mobile now from what i have found there are only two way's of unlocking both are via unlock codes and from what I've read i can get it free from t-mobile but i also believe you have to of been a t-mobile customer for 2 months plus or something any you guys know if this is true?
The other option is to get one of these websites that give you unlock codes has anyone used these could you if possible tell me what sites are genuine and safe to use?
Another thing is there any other way's of unlocking the phone?? that i have missed? i haven't actually got it yet but its being posted as we speak..
Hope this is the right place to post this and cheers for you input ;D

T-mobile will give it free if your a longstanding customer. If you want to buy it, buy it from ebay. There is another thread in this section (actually more like 20, one of which has a link)
Yea they wont give you the code unless you have been a customer for 90 days or more. The site I used was http://www.unlock-tmobileg1.com it took about 10 hours for the code to arrive, they have detailed instructions on how to register an ATT APN so you can do the initial google setup too. I think they offer codes in 2 hours now, but either way its a good site and I think its just over 20 bucks, like 22 or 23. I looked on ebay but it didn't have a good feel to it, for me anyway.
edit: One great thing about using it on att is that they wont know its a smartphone because its not in there system so you can use the $15/month dumb phone unlimited data plan and it works great, I have been using it for about 3 months now, only downside is att and tmobile use different 3G bands so it is impossible to get 3G with att.
Only use unlock sites who people here say they have used. Don't be fooled by some of them which are *very* cheap (as in, a quater or the cost of most), these will normally tell you *how* to unlock your phone (call t-mobile or buy a code, but they dont give you the code).
I bought my code of eBay, that way you can look at there feed back and you know that the testimonies on their flashy website aren't fake.
Cool cheers guys thought that'd be the case phone still hasn't arrived yet so until then...

Some unlocks can be done for free using a custom ROM flash. The operating system is only setup to bar off any non-TMobile sims, so do a flash, and bang, that SIM restriction should be gone.
I have never heard of any rom unlocking the phone, the carrier lock is much deeper in the phone, hence why you dont lose your unlock status when you switch rom's. I did a ton of searching before I unlocked my G1 and never saw anything like what you speak of, I had already rooted and flashed 3 or 4 different roms when my phone was still locked and it never made a difference, so could you please provide a link to this type of rom? And just so you know, in your sig you list phone OS's but what you are talking about is rom's as the only OS for the G1 is Android.

I don't think that's right either. I've heard quite a few people say that after rooting and flashing a non-tmo ROM their SIM was still locked...

He might be confused with something else because of all the smartphones I have had I've never heard a rom to unlock your sim/carrier. I wish there was though but if you think about it you would never be able to change your rom because you would lose the unlock status.

Solved: Unlock the Acer Liquid E

(Edit: see post #10)
Not to get hopes up... I haven't figured this out yet, but I thought I should start a thread.
Has anyone discovered how to unlock the Rogers Acer liquid e. I havent found a website or forum - yet - that is able to do this. It must be possible. I called Rogers, who told me to have it unlocked by someone.... yeah, thanks boneheads... i hadn't thought of that.
Surely it can't be legal in Canada for them to keep something -that i have purchased- locked to their network? Right now my phone makes a nice door stop.
Anyways here's to hope.... and a Canada Day beer once ive finished my post.
mmm.... tasty beverage.....
I bet the LCR rom is unlocked.
Realistically, once you've rooted your LiquidE you should be able to unlock it using the shell like in any of the other android phones. All it takes is root access, and that's fairly easy.
See here for instructions to both root and install LCR 1.7 on the Liquid E:
Code:
hxxp://howardforums.com/showthread.php/1655375-Acer-Liquid-E-Owners-Unite!
One more thing to note is that the Rogers ROM comes with out the voice-command-input, and it cannot be activated (even with root access, I repeatedly failed to get it working). Once on the LCR 1.7 ROM, it works like a charm (enable HTC IME keyboard).
Just be sure to make a nandroid backup before each step, so you can recover (especially immediately after installing the Malez 0.5.3 recover tool, when you still have your Rogers ROM untouched and unrooted).
If you can get me a non Rogers/Fido/7-11-pay-as-you-go SIM card to test with (e.g. Cingular, AT&T, etc.), I would be happy to test it on my LiquidE with the LCR 1.7.1 ROM to see if it's network unlocked.
I am in Vancouver.

Okay, Ill give it a shot and if no go than ill get you a card..... thanks for the reply. After being on the Hero forum with its numerous users for the past 9 months im glad to get a prompt response from someone here at the Liquid forum.
Cheers
Okay rooted with LCR 1.7.1..... now how do i sim unlock using the shell? Anyone?
If I remember well, it's impossible right now to unlock Acer Liquid E shipped by Rogers.
One dev from France has tried to flash his phone (unlocked) with a Rogers dump, and after that, his phone has been locked to Rogers's network.
No way to unlock it, he had to buy another Liquid.
So, for now, I think nobody managed to unlock the phone, but there must be a trick to do it I think.
Good luck.

Impossible? Nahhhhhh. Where there's a will.....
I am confident that someone here at XDA will figure it out soon enough. There are some pretty smart folks around here.
I suppose i should buy another phone in the meantime as I am without at present. When I bought my LiquidE used ($250cnd), I never expected this unlock problem.
Now Im less $250 and a phone. Damn.
Bad for you
No way to ask Rogers for the unlock code, even by paying a little ?
Rogers is about as helpful as telus on these matters. "we do not have unlock codes available... we dont have access.... blah blah blah...."
Edit: I have now tried Rogers again and offered them money... still no go. I also called Acer Canada support and they state that they have no way of accessing unlock codes for Rogers exclusive phones. Corporate rubbish.

YEEEESSSSSSSS!!!!!!!!!! Thank you so much. The above link from EBay worked! Booyah!
I paid, sent my IMEI, and within a couple of hours..... voila; unlocked. I am now on the telus network with a Rogers exclusive(?) phone. Feels so good to stick it to em!
Now if I can only get a refund from the other sites i tried..... ????!!!????
I thought I read in one of the threads here or at modaco (by malez maybe?) that said there was a text file that has a line that says something like 'lock = 1', and by rooting and editing that to say 0 is enough to unlock. Not sure if it was verified. Worth a try anyway if the phone's already rooted. Just have to search for 'lock' string in the system files.
Apparently, some people have tried that (like vache) and it didn't worked
Solved: Unlock the Acer Liquid E
That's exciting news !!!! I have tried 3 different online sites all of whom
could not find a code for my 1 month old rogers liquidE.
I have asked the site mentioned in this thread if they can do it and gave them my IMEI as I do not want to send another site more money just to have them say no and wait and go through the refund process or worse, chase them for the money.
Hoping for good news from them.
When you got you code, was it as simple as inserting it into the little window that pops up when you put in a different (non-rogers) sim ?
Thanks
Yes, the little window. You get ten tries before the phone self destructs taking the world, the universe, and everything with it.
I went through the same process as you and lo and behold it worked.
Good luck.

Can anyone confirm that you cannot use a Rogers Acer Liquid on a Fido account without it being unlocked. They are the same company after all. Thanks!
I confirm, you must unlock first, or nothing but 911
Cheers! I guess I will have to pony up and get her unlocked. Thanks!
Didn't work for me
I have a Rogers Acer Liquid.
I made the purchase but he couldn't find the unlock code for me.
But he gave me a refund.
Rogers must be tightening security on this.

[Q] UNLOCK AT&T Samsung Captivate (SGH-i897)

New on this android thing - noob question:
Has anybody a prove link getting an unlock code for AT&T Captivate (SGH-i897)?
Want to use this phone in Europe with vodafone...
Thanks in Advance for you help

No, there is no solution available at the moment. A couple of people have been able to persuade ATT to give them codes after many days of phone calls and support chat. A few have had some varying success with turbo sims that supposedly fool the phone into thinking the sim is an ATT sim, but that's it.
based on what I have read online. ATT often will unlock your phone when you are in the contract for like 6 months or a year.
I called them with my tilt 2 about a year into my contract. Tell them that I am traveling oversea and want to use the phone internationally. They gave me the code without much hassle.
Not sure if this is partially due to the fact I have been with ATT for years.
Online search also shows that ATT will often unlock almost all smartphoen for you except iPhone, so keep try them and if the CSR does not help, ask for supervisor.

The official requirements are:
1. at least 90 days into a contract
2. Have a post paid account with contract
3. Paid all bills on time.

Captivate has proven to be an exception to this. There is already a long thread about Sim Unlock. The bottom line is AT&T won't give you a unlock code for Captivate until 10 months later.

If you're not an AT&T customer, they typically won't help you with unlock at all. Good luck.
Not sure why there is another unlock thread, but At&T told me they would. Unlock in 90 days. I have no reason to doubt them.

unlock Captivate with froyo
today i unlocked my captivate with an app called Galaxy S Unlock get it in the market very easy to do also on youtube i am running froyo 2.2, version I897ucji6 and i am rooted (need to be rooted)
Finally got the captivate to unlock and accept the tmobile sim today. Everything seems to be working fine so far. No data on the plan but using wifi til I add data. One thing I'm really curious about is.... Now that the phone is unlocked and working, If I flash a custom rom (say cognition for example) will I lose the "unlock" ?
*edit* forgot to say how I did it... I just simply flashed back to stock 2.1, master cleared,rooted, installed busybox and galaxy unlock app, used the #2 method with the unlock app and it worked. PATIENCE IS KEY! ===> It takes a good 2-4 minutes for the tmobile signal to kick in so it may seem as if the unlock failed but it just takes alot longer than the at&t signal to kick in.

[Q] Unlocking tmobile usa HD7 a sure thing?

Hey guys I've asked this in some thread before but never got an answer. I live in Canada and was thinking of telling my friend who's in the US right now to get me a contract free HD7 from tmobile so I can unlock it and then use it here. So I just want to know if it's a 100% sure thing that the phone can be unlocked before I buy it since I won't be able to return it in case it can't be unlocked. I don't want to end up with a 500$ paperweight since I've read that some people couldn't unlock theirs.
Because if it's not a sure thing, I guess I'll be getting the optimus 7..
Thanks!
T-Mobile will give the unlock codes after you've been a customer for a certain period of time. The length of that period and what happens to it when you've bought the phone at the unsubsidized price are somewhat variable and honestly I would not rely on this happening if you are not a T-Mobile customer.
However www.htcimeiunlock.com will probably be able to unlock the phone; I personally unlocked an HD7 in 15 minutes with their service. Bring a laptop or something and check the IMEI right in the TMOUS store before completing the purchase -- the site will tell you definitively whether it has the code for your specific device.
Like I said I'm not personally going there. My not-so-tech-savvy friend is so I can't ask him to do that. But do u think that eventually after a certain period of time that ALL htc phones' unlock codes will be available or are some just never unlockable?

It's almost certain that it will be available now. And if not, it will be soon enough. I wouldn't worry about it. Worst case scenario is that you have your not so tech savvy friend call tmobile and get the code for you. It shouldn't even come to that though.
I am having trouble getting my HD7 unlocked. I tried www.htcimeiunlock.com and it does not recognize my IMEI. I'm trying to get it unlocked at a different website and they have to contact HTC directly to get the unlock code.
Hi...
I bought one from T-mobile and he told me after 45 days I can call him to give me the unlock code.... But I couldn't wait and I used this website cellunlocker.net to unlock my device and it's working without any problem....Thanks!!!
I also ordered an unlock from Cellunlock.net last week.. Still waiting on a code for my HD7. Apparently HTC is way behind on providing codes to the unlockers for newer batches of phones. Getting annoyed either way, I have this HD7 in Toronto that I can't use.
It's a sure thing as I am using a T-Mobile HTC HD7 on FIDO, so the phone is unlocked. I'll sell you mine if you are in Toronto. T-Mobile phones are different band so you can only get Edge data through it. Kind of sucks if you are use to 3G speed. If you are going to use the phone on Wind then it's same band and you will get high speed data. Anyway it is possible to unlock - I've been using the phone on FIDO for almost 3 weeks now.
I have used www.cellunlocker.net to successfully unlock two of my HD7's. Codes came via email within 30 mins, both times.

Thanks Guys,
So, Rooting does automatically unlock the G1?
I purchased a G1 on ebay, and apparently, it is unlocked, but it looks like the original 1.6 is still there. So I am wondering how that is done.
Doesn't really matter anyways, I am going to root it when it gets here.
Heeter
You can unlock G1 on 1.6, that is what I did with my G1 from T-Mobile. Once unlocked, it stay unlocked.
Unlocking has nothing to do with rooting your G1. Rooting give you administrative privilage so you can do what you want on the phone.
So, BA.
How did you unlock it?
Heeter
Got the unlock code FREE from T-Mobile. Basically, call them up and requested the unlock code. After a certain time T-Mobile will give you the unlock code (when you requested) if you needed to unlock your G1 when you go on a trip (that required you to use the other network) to different place (IE: other country). That is what I did.
In your case, if you are not the original owner of the G1 with the T-Mobile account, and the G1 is not unlocked. You'll probably have to pay for the unlock code. My brother pass me down the G1, so that what we did.
Awesome, thanks for explaination, BA

Rooting does not unlock your phone. Nor does it work the other way around, they are completely separate.
The only way to get the unlock code free is to get it from T-mobile, which they will really only give you if you got your phone from them. You can use virgin mobile without unlocking.
advice please

the phone belongs to my brother but he was told that he will have to pay £15 to get unlock code from tmobile.
if i buy unlock code from e.g. ebay will the phone stay sim unlocked even if i upgrade/downgrade operating system?
also - after sim unlock- will g1 be able to access data from other networks at registration stage (just after booting)?

Yes & yes, the network lock has nothing to do with the OS.
I looked around for a bit when I first got my UK G1 a few days ago trying to figure out the same question.
Unlocking and rooting are completely separate. There is no way to unlock your phone by rooting it or installing software hacks or mods. Also, once you unlock your phone using a code from TMB or eBay, etc. it will ALWAYS stay unlocked, no matter what you do in terms of rooting, installing custom ROMs, etc.
I just paid £3.85 for an unlock code from eBay instead. I got it within a few minutes and it worked immediately. Now I'm using it with my Orange SIM card without any problems. I would have phoned T-Mobile up but I'm not the original owner of the phone and I didn't want to hassle the original owner with it, since he had already given me the phone for free. So paying a few quid for an unlock code didn't really bother me.
Wow, I went a bit off-topic there, lol
