Unlock the G1 without unlock code ?

got root on the G1 already ,possible unlock the G1 without unlock code
anyone working on it ?
I think there are 3 possible ways:
1:find the unlock flag then rewrite
2:find the IMEI code and change it to a IMEI code that has already got the unlock code
3:find the unlock algorithm

hack the baseband
Did you figure out something? I got my T-Mobile G1 bought off eBay in the brand new packaging with a SIM card. Probably someone stole it from BestBuy or Futureshop, whatever, but I generally don't care where it came from bradn new that cheap
But now NO ONE can provide me with an UNLOCK code for it
I tried several different unlock sites, including the most famous one mentioned here, but no one can actually calculate an unlock code based on my IMEI.
I tried some solutions like Gevey 3G / TurboSIM for G1, but eventually the phone with a "proxy" SIM sort of "sees" my SIM card, but still unable to register to the network.
I was wondering if any cable unlock solution was found for the G1 already.
I got the phone rooted with the latest baseband and with the latest self-made build off the android repository, but cannot figure out how to unSIMlock it now..

find someone with t-mobile, have them activate the phone on their line, then use a site or hopefully they have been with t-mo long enough to add international calling, tell them you require the phone unlocked to use a euro sim and your set
disclaimer: in theory
all of the above except adding a stolen phone to t-mo actually work [might still work, not like your responsible for ebay origins] and t-mo's great customer service will unlock it for you immediately if your account qualifies for international calling,

Call T-Mobile

Sounds crazy, not sure at all if it's been mentioned before but try www.htcunlock.com
They claim to be able to get any code for almost any htc phone including the G1, you can also buy codes in bulk to lower the cost, and its paid through paypal, so its kinda secure
Just my thoughts anyway
Oh and if you are unlocked but have no network, try setting up the APNs in wireless settings

Be prepared to wait several days for an unlock code from tmobile.

I got mine in 3 days. They were even faster when I had my BlackBerry.

yup, been much faster than estimated all 5 times I unlocked my mobiles

I was unlocking the G1 for £3.50 using a site I had access to. I was getting the unlock codes back within an hour too.
PM me if you want your phone done.

No in fact, don't PM me as I don't have the access any more.
The website that can do it is Uniquephones.com

LMFAO...GNR

Hi all, I have a similar experience. We have a G1 here that was never linked to a contract, and T-Mobile refuse to acknowledge its existence. I have tries one unlocking company so far, and they claimed they were unable to get the code. Does this mean I will not be able to get the unlock code for my phone at all?

if its saying that its unable to register on the network then that usually means the sim has been disabled or that the phone has been reported stolen and the IMEI blocked

seems like nobody have a "flash scan" to get our SIMUNLOCK code

Thats the strange thing, it is simply locked to tmobile, a tmobile sim works in the phone, and all is good, but it is locked from other networks (asks for code)

how to unlock g1 without foreign sim card?

I just received unlock instructions from tmobile, including the unlock code. The first step, howwver, is to insert a foreign sim card. I haven't left the country yet so I don't have one. Is there a way to proceed without a foreign sim card? I had a brand new sim card lying around and I tried using that, but after reboot it never asked me for the unlock code it just booted up into the home screen and asked me to sign into gmail. Any suggestions?

In wich carrier is the phone locked now? Tmo? If is on Tmo, and the sim isnt from Tmo, then your phone is already unlocked...if the sim is from the same carrier than your phone, then you need another carrier sim to unlock it...

He wants to unlock his phone without a foreign sim card. When you unlock, to be able to see the Unlock Code input screen a different sim card than your carriers must be in the phone. He wants to unlock without the second sim card.

You are perfectly allowed to post that, however that is not what he is looking for at all.

Just find a friend with AT&T and borrow their SIM card for the 5 minutes it takes to unlock the phone.

Dang, I used to work for T-Mobile in the PDA dept and never realized this limitation. I don't *know* anyone who has an AT&T phone and am selling my G1, need to be able to get it unlocked. Everyone I know uses either T-Mobile, Verizon or Sprint. I would hate to have to send the buyer the unlock code and have them do it themselves. Almost any other phone has a # code to type in, why not the G1?

Looks like it's not a G1 thing but a T-mobile thing. I had to use another non T-mobile SIM to unlock my HD7 as I am selling it.

The best thing you can do is see if any of your friend has a different carrier sim (IE: AT&T, Verizon, Sprint) and put it in. After you turn on the phone, it will then come up with the box that prompt you to put in your unlock code.

I have a UK SIM card coming in a couple of days, and I have received my unlock code from TMO. I will not be traveling to the UK until September, but want to test the unlock code now just in case TMO messed it up. is there any downside to inserting the UK SIM card in the G1 in the US just for unlocking purposes?
For more input, my phone is rooted, running DWANG 1.6 ROM. I intend to do a full nandroid backup prior to testing, and will also delete quite a few of my apps prior to traveling since I don't want to have lots of data usage when I am overseas. When I get back home I will restore from my backup. Anybody see any flaws with this plan?
Thanks.

having problems unlocking the sim on my phone.

I'm not sure if this is the right place to ask this question but it did say general for the htc kaiser.
I've recently acquired a htc kaiser from a friend. I contacted at&t for the unlock code but they gave me the wrong one. By the time I recieved the correct code I could no longer attemt to unlock the phone because there had already been 5 attempts. I have seen on some of the posts here that after 5 attempts the phone is permantly locked. Is there any way to get past this issue? Can i still use the kaiser sim unlocker without bricking the phone?

If you used your PIN 5 times you will need to enter your PUK code (You should ask AT&T for it, If you didn't get it when you received your sim)

I appologize I wasn't specific enough. My carrier is T-mobile and the phone is from at&t. I trying to unlock the phone so it will recognize my sim. There has been five attempts to unlock it and now it will let me input a code but I can't use the ok button to process the code. The message on the screen says "please wait until timeout is over." I did try using the puk code but it wouldn't let me confirm the code.

I already have the 8 digit unlock code from at&t.

Unlock issue with UK i9305 - won't work with Three (3) network sim!

I'll try and keep this breif but getting pretty frustrated with this...
I bought this handset sim free from T-Mobile UK. It was brand new and sealed. When inserting my Three(3) sim it would say "invalid sim" - which was expected as it was locked to T-Mobile. I paid a third party UK company called mobileunlocked.co.uk who have a very good reputation and lots of good reviews for an unlock code so I could use it with a Three (3) UK 3G Sim card. I received the unlock code and an un-freeze code and used both several times, resulting in "unsuccessful". Thinking it was a bad code, I paid ANOTHER unlocking company off ebay (again, reputable) and was supplied with the same codes and the same results but a slightly different method which involved entering * and # keys before the codes in the code box. This resulted in a popup saying "Network control code is blocked".
Following this, I tried the *#197328640# method to access the hidden menus as detailed in this thread http://forum.xda-developers.com/showthread.php?t=2014982 (this has been proven to work with Note II, Galaxy SIII and Galaxy SIII LTE).
I followed that guide to the letter and restarted the phone. At first, I had hope as there was no sim lock code entry box, however I waited and waited and waited and the phone did not pick up my Three (3) signal, despite it no longer saying "invalid sim".
Basically, it just shows several bars but does not pick a Three(3) signal or any date. I have tried manually selecting the network and manually entering APN settings, but I get the same result. When I try connecting manually it just says "Cannot register on network".
-I have tried using this sim card in other phones, it works OK!
-I have tried using other network sim cards (Orange, T-Mobile, EE, Vodafone) and they all work.
-I have tried using a different Three(3) sim in this phone and it still doesn't work.
I can't return it to the T-Mobile store as the warranty is invalid as I have unlocked it (or so I think!). Can anyone help? I know three(3) sims are compatible with this phone as others on this forum have stated they are using Three (3) sims in unlocked i9305s.
Any idea why my unlocking codes that were valid wouldn't work and why it said "Network control code is blocked"?
Any idea why my Three(3) micro sims won't work but other networks do despite this phone being compatible with three (3) sims?
Help!

It doesn't appear that 3 UK has any publicly available LTE network at this time, but that they are rolling one out. Perhaps it is physically available and being picked up by your phone, except 3 isn't allowing just any sim card to register on that network at this time? Try disabling LTE and attempting to connect again.

I know I won't be able to get LTE as Three (3) aren't offering LTE until Q3. I am perfectly happy just using 3G. I have tried disabling LTE and using 3G only and the same things happen.
I have tried 2 different Three (3) micro sims in it and it still won't register on the network. I know Three(3) sims work in the i9305 as others have unlocked their's and used Three (3) sims.
It's either something wrong with the unlock, something wrong with the hardware or something isn't enabled/disabled. Like I said I've tried automatically connecting and manually entering APNs and still NOTHING.
Frustrating having spent over £450 on a brand new handset which I can't return as warranty is invalidated through "unlocking" (which hasn't unlocked it fully!)

Shouldn't be a problem to be honest. Have you tried calling three to say that you're using the i9305? I love three and their unlimited data plans I plan to do this once samsung/EE unlock my phone.

Hi,
I am in the same boat, I actually got the S3 LTE from EE in December (GOT IT FOR 359).. Initially, it worked with three after unlocking via xda..*#197328640# method ..But it stopped working or it was working intermittently...
So tried rining three..they said..ohhh our network is best and our (three) sims will work only in three mobiles..
Anyway I tried all other methods..re-set..factory etc..
Finally sent the mobile to Samsung...
after 10days, I got it back...Now as soon as I insert three sim..it says invalid sim..So tried *#197328640# method again..unfortunately..i can't do that as (the last option INITIALIZE...) does not show up now..
Anyway managed to get unlock code from ebay...NO USE..it shows the same problem as yours.."network control is blocked"...
Donno what to do??? might ring samsung again tomorrow...
Have you tried speaking to T mobile about getting it unlocked????
If you find any answers..pls let me know
Thanks in advance

I'm having the same problem. Any updated on how things went with T-mobile or does anyone have a fix?

Should I cancel my order?!
I just bought the S3 LTE i9305. I purchased it as an upgrade and its arriving tomorrow. I wanted to give my sim to my mother and keep the phone to use with Three's DC-HSPA+ which will work on the S3 LTE. So can I unlock it or will it be facing the same problems as mentioned in the thread. Sorry for not helping out, ama noob and GOOD LUCK! :good:

I recently put in an unlocking request at EE. They get a samsung unlocking code directly from Samsung. So I'll give this method a go. I am getting my Sim Card in soon from three. Decided to jump the boat on to the one plan @ £25 a month. =) EE's london signal is pants. =(

I tried to get an unlock code from T-mobile, they said that Samsung wouldn't release it for another six months, since it's a new phone. Even though we've been with them for donkeys years!

Right today, I recieved my sim. I'm glad to say everything works. I'm getting around 8mbps down and 1mbps up in West London.
If yours doesnt work then it probably is a damaged sim.
Tell T-Mobile you want to speak to someone that knows what they are talking about. It takes up to 60 days for direct Samsung unlock code. You might have to pay a tenner but worth it jn my perspective. I'm glad I have unlimited data again. It feels like freedom. No Joke. o2 Used to do an unlimited tariff and I loved it. There reasoning was to improve their network but instead it made it worse. I know Three arent known for their calls but they certainly know what customers want and thats data.
PS how do I know if im getting the optimum speed?

I think you have updated the software via OTA.. you need to downgrade to I9305XXALI5_I9305EVRALI5_I9305BVALI5 (this is for people who have got phone from T-mobile). Download from Sammobile.com, flash via odin (this wont affect ur warranty as this is stock firmware and doesnt increase the binary counter).
once you are sure that you have the above software, then follow the instructions on the below in first post in the mentioned link, again no rooting involved:
http://forum.xda-developers.com/showthread.php?t=2014982
People have confirmed that after unlocking via this method if you go ahead with OTA, you will still have the phone unlocked.
I have followed the above procedure but havent updated the firware and have not used the phone yet. But its unlocked and I have tried using Three UK sim, it works,
Do let me know how it goes.

On the site, it says it's for EE, is that still ok? I know T-mobile, Orange and EE, are all pretty much the same thing now, but I just want to be sure. I wouldn't want to put something that starts putting EE logos all over on boot up etc. The one that came with the phone doesn't mention anything about T-mobile on boot up.

It won't EE is unbranded

Thanks... I've zapped it with 4.1.1, used that trick, and then allowed the 4.1.2 update + plus another update of some sort through OTA, and I'm now using O2 happily! Cheers!

H811 LG G4 Network Unlock Help needed or different stock firmware

I have lg g4 from tmobile with a tmobile device unlock app. It does not ask for network unlock code either with a different carrier. Also it does not pop up the network unlock code window even if i type the 2945 code (ithink). IF i use device unlock app it says device unknown by provider please contact customer care. I ordered service remote unlock they where unable to unlock but they had to refund the money because they could not unlock.
Funny think is T-Mobile is saying its not a T-Mobile phone because they cannot find the IMEI number in their system.
The phone is an original T-Mobile phone, with original T-Mobile packaging, software and original labels with the imei.
The only way to unlock this phone is if i can flash stock firmware on the h811 without the tmobile crap.
am i screwed?

How long have you used that phone for as of now? T-mobile requires you to use the phone at least 40 days on their network and it needs to be paid in full if it's financed. I yours is still financed maybe the op that thread could help you http://forum.xda-developers.com/g4/general/t-mobile-free-sim-unlock-promotion-t3138438

Can you link us to the App that unlocked it?

please read my post again. tmobile sim is working fine on it. It does not reach even the permanent or temporary unlock option.
T-Mobile customer service does not even recognize the imei number at all. They say its not tmobile phone and clearly is.

1) Does the IMEI in settings match the IMEI on the box/back label?
2) Are you sure this is a T-Mobile US phone and not a T-Mobile european phone?
3) Where did you buy it? (direct from TMO, eBay, CL?)

please read his post again. you must use the phone with your t-mobile SIM card in it for at least a week until its IMEI (dial *#06# to display it) shows up in the "Check Unlock Status" pop-up in the Phone section of the My T-Mobile website. If it doesn't show your IMEI there, the phone is not associated with your account and the unlock app will not work.
