Has anyone unlocked their g1 running on cyanogen?

Well, the story goes like this:
Bought a g1 and the second logical step was to put in cyanogen. After a while I thought that an unlocked phone would be even better. Went online and purchased the unlock code and tried to use it while running cyanogen. Did not work. Flashed to rc29, tried again, did not work. Then I went to another unlock provider and this guy, gave me the same code as the first, based on my IMEI ( I don't have a fake IMEI), he tried it as well and did not work. Then he searched for different version of the code based on the IMEI for different htc products ( it seems that they have some accounts with htc and for IMEI they receive the unlock code). We also tried it with a goldcard which only made my g1 scream that I don't have a simcard inside.
Bottom line, did cyanogen mood do something to the unlock procedure ( hard locked the phone on tmobile - on tmobile the phone works fine) ? Or I just happened to have a weird phone, Thank you.
Btw, my unlock code is 92179512. Feel free to try it. It would be funny as hell if it were to unlock someone elses phone, and if it does, let me know as well.

I unlocked my phone on a MUCH older version of CM, so I wouldnt be able to tell you if anything has changed to effect the process. However, if you're a TMO customer, you do know that after 90 days they will GIVE you the unlock code for free, right?

I also have unlocked it on Cyanogen mod, but I believe I was on 4.2.7.1 at the time.... not that long ago really.... but T-Mobile does indeed give away the unlock code for free, and it worked flawlessly.

Neither the ROM, SPL or radio can effect the simlock. It's not Cy's ROM that's causing the problem...
What do you mean 'it doesn't work'? Does the phone reject the code?

Thank you for the reply. Well the problem is that I don't have a contract with Tmobile since I don't have the money for it. I bought it off from someone and used Tmobile prepaid sim card, which works fine. And, because of that, Tmobile won't provide me with an unlock code .
Regarding the code, when I type in the code it says network unlock unsuccessful, so I can't do much about it. I'm trying to update to the latest stock donut and see what happens.

Ah that sucks :-( I really can't of any options for you, since any codes generated will always be the same...

nope -

notice in the replies above, that cyanogen nor spl, nor anything software related can change your unlock status.
you already have an unlock code, and since you've had it generated from two different sources, i believe that code is correct for THAT IMEI number. that being said, did you copy the imei number from the sticker on the inside, or from what the phone shows in "PHONE INFO" ? I'd make sure they both match.
i also have a phone that is flacky about SIMs. haven't found an explanation yet, I think some of the boards have bad solder joints, or there is another hardware problem that causes similar errors. no proof yet.
try a friends Tmo sim card, and if his is recognized, and allows data connection, you'll know it's your phone that is locked, and that all the hardware is working. i'll bet you entered the wrong code because the sticker inside was wrong, or you fat fingered it. just a guess.
good luck, please update the thread when/if you find a definite answer.

I would bet the IMEI on the sticker and on the board are different... where did you buy said phone and for how much? It could very well be a refurb, which will have bits and pieces from several different phones, and thus could have the SIM locked guts for phone 666 and the case from phone 888 type thing.

Yep, checked it 10 times the first time I bought the code online. The same imei in about this phone is on the sticker. After I saw it did not work, I went to a local unlock shop around my place and the guy there checked it again more than 6 times. So.. weird eh? And both guys got the same code from HTC based on that IMEI

Sounds like this may be a hardware error. If that is the unlock that is generated then it should just work. The unlock does not really pertain to the rom or anything else that people usually mod. Also, maybe ask that dude why he was giving up that phone, maybe there is really something wrong with it.

the only other thing left is get an turbo unlocker chip that sits between SIM and phone
pain in ass to install but I have done it with out cutting the SIM card
I am guessing someone had typed the code in incorectly .. they can be permiatly locked if wrong code has been entered
also just because it was another person does not mean their MEI source wasn't the same
I guess they worked out they work ,,, I payed $5 for mine .. now 4x the price
http://cgi.ebay.com.au/NEXT-SIM-TUR...wItemQQptZPDA_Accessories?hash=item4cec3cab8c

The unlock codes sources are all the same. I lost over 100$ trying to get unlock codes from them but 80% of them don't work (only the ones for htc phones). I use a turbo sim with my G1 and is really easy to install. just buy one and cut your sim where the CHIP from the turbo sim is located. It works flawlessly.

Im just throwing this out there to say that I was able to successfully unlock my g1 with CM 4.2.10.1
Other than that I would just be repeating what was already said if I was to give any advice.
Best of luck man.

You're welcome to try it with my sim card. But you're probably far far away.

Actually, they will give you an unlock code after 90 days of being a customer and every 90 after the last time you got an unlock code. They will give you an unlock code the same day you buy the phone if you meet those requirements.

Sorry if this is irrelevant to the rest of the thread, but assuming I unlock on JF 1.5 (yea I'm behind) to ATT, and wipe everything to install a HeroUI ROM of some sort, will the unlock still be in effect or will I need to unlock the phone again?
Thanks.

You'll be ok.
I actually like JUST did it on a coworkers(I admit, going from WiMo to Android is a learning curve, but its easy), he got his from craigslist, had JF 1.5 on it. He used it for like a week, complained about sluggishness (he did have like 20 apps constantly running) Anyway, after a few beers and lurking here (it was when I was deciding what HTC to get) we decided to go to CM (latest build). Everything went fine step by step.
I cannot vouch for your particular ROM but for CM it was fine.

need to unlock this without a non-carrier sim

i have the unlock code from att but i was like "nah i don't need the instruction emailed to me...youtube bro" little did i know...is there a way to do it without a non carrier sim?

I don't think...

Just by coincidence I've been researching around lately to unlock my Motorola Bravo phone so that I can use it on any network I wish. I have already "rooted" it, which I remember was quite easy (I think what most people complain about is the amount of time it can take and the number of steps that can be involved), but, as you most likely know, rooting and unlocking are completely separate, independent functions on the phone. I searched Google, a bunch of message boards like this one here (this has always been my favorite...lots of extremely intelligent people), even some torrent files, but despite hours of searching, I unfortunately couldn't find any way to unlock the phone without just paying for the code. Yes, you can get it free from your carrier, but my account has been cancelled for months and I no longer have that option. Luckily paying for the code is very cheap and should cost you less dollars than the number of digits on your hands...if not keep looking b/c you're getting ripped off.
Theoretically, that is if my theory of how the phone functions is correct, there should be a way. I mean, if unlocking is done purely through software, there's gotta be a way to crack that part of the software and trick the phone into thinking the correct unlock code has been entered. I know the whole IMEI number to unlock code generation process uses an encrypted algorithm to work, so I don't know how difficult or impossible that would be, but that's one way I can think of doing it. Another way I thought of that seems like it should work, although I haven't heard anyone that has done this specifically say that it also unlocked their phone, is to totally wipe the phone and reflash it with a generic/unbranded version of Android. Would either of these options work anyone?

You might, MIGHT, be able to use the Defy Soft Sim Unlock, but its for a different baseband than what we use (not in /system/etc/motorola, but in /dev/block/mmcblk1p14 -- actual radio partition). I attempted to flash the Defy radio.img, but I ended up having to flash the sbf so don't flash the baseband zip on that page. Go to Defy General and go to the Stickied Wiki or Beginner's Guide and it'll have all the info you need on this.
'
While I'm hopeful for you, I doubt it will work but its worth trying. You can also try motofan.ru and see if they can provide an unlock code for your Bravo (its free). Its a 50\50 chance that they can or can't.
Your only other option is forking over the $$$ and buying the code. Don't try to randomly guess it -- you only have 10 tries and once you use them all you're (possibly) screwed.

Regarding unlock problem(network re-locked)

Who already got permanant unlocked guys, Can you let me know "Device Unlock" app icon dispaying on the App drawer after Factory reset.
I known that Device unlock icon should be gone(Exactly Disabled in App manager) and first permanent unlocked success, Device unlock app gone(As Disabled). Do factory reset then still Device unlock app gone(Disabled) in the App drawer? If keep permanent unlock and run device unlock app, what kind of message dispaying in the Device unlock app? Can you capture and share to here?
Also have you ever been network relocked symptom? I had Tmobole note5 and it suddenly network relocked. Reason is mystery. One day I just eject the sim then insert the sim. Thats it.
Who same experinced guys, how can you resolve this relock problem?

Yes, Actually i asked at least 10 times or over about this re-lock problem.
But no luck. They said that network relocked meaning is just network locking problem and this Note5 IMEI indicate outstanding balance or financing.
T-mobile REP. said device contract & financing problem only resolve account owner. But this account owner(ebay seller) cant't reach now. Because I bought this item one year ago.
Yeah, I was using this T-mobile Note5 unlocked status about one year. But after one year and one day, it suddenly relocked. Still i can't believe why my Note5 re-locked.
The important thing is previous owner(ebay seller) now can't reach out. May he is busy or he no longer login to ebay.
At least i don't have to request T-mobile unlock officially. Because i am not real owner of this Note5 device.
So i found 3rd party unlock service, but recently t-mobile device unlock app service price is increased to $130. Its too high cost for unlocking.
I am very confusing how can i resolve this network relock problem.
Think of it, when i first reviced this unlocked T-mobile note5 from ebay buyer, Device unlock app exists on app drawer.
(Refer the Attachment #1 image)
So, when i executed the Device unlock app, message indicate as below.
(Refer the Attachment #2 image)
Code:
Unlock failed
Unlock approved : Mobile device is permanently unlocked.
I think above unlock fail message is wrong and above message keep since network relocked.

So.. Have you tried a different carrier sim on it to confirm if it's locked or not? If you're using only T-Mobile, why are you worried about device unlock app?

Sure, Actually I am living at South Korea, So everytime korean SIM insert into this device and still locked as attached screenshot.
I hope to verify this "Device unlock" app's concept for verify my Note5 relock problem.
As I already said my Note5 device unlock app keep displaying at App drawer since permanent unlocked.
I think that is incorrect symptom and hope to know this T-mobile unlock concept
Code:
https://support.t-mobile.com/docs/DOC-14011
If you completed a Permanent Unlock, the applications disappear from the device app list.
verified or changed on Galaxy S7 edge(G935T) model.
Really curious point is When permanent unlocked, Device unlock app disappear /disabled from App drawer even though after Factory reset.

I'm not sure if it was factory unlocked by T-Mobile or if it was unlocked by 3rd party and sold on ebay.. my opinion is that several people have unlocked by T-Mobile and they have installed G935U Rom so it doesn't lock itself.. your best bet might be T-Mobile support with details of your usage or 3rd party unlock..

Thanks your detail explanation and good advice.
Regarding official T-mobile response, they said as follows.
Code:
That being said, it's definitely important to know that if it's a T-Mobile Note 5 and you try to use a different carrier's SIM card in it, it may not work unless the device is SIM unlocked to accept service from another carrier. Even more important to note is that the device will ALWAYS be tied to the original owner. This means even if it has a clean IMEI now, if something happens down the road (it's not fully paid off yet, and the original owner stops making payments on it, or if they report it as lost/stolen to insurance, or if they simply reach out to us and request to block the IMEI), this can change that status at any time. There is no way to prevent this, and if it does happen, the only way to get it unblocked is for the original owner to reach out to take care of whatever the issue is. Does this all make sense? I want to be sure, so you don't run into an issue where you buy a phone that you someday cannot use! Let me know what questions you have!
In short, T-mobile device always tied to original user if device have finaning, only original user can resolve this problem, not second buyer like me(ebay buyer)
Yeah, I think remain key is only 3rd party unlock solution. But 3rd party unlock solution price is now too expensive. About $130
Hope to 3rd party unlock price go down nearby $50.
To. ALL
My main question is still not resolve. Can you let me know following my question if you have permanent unlocked G935T model?
Can you let me know "Device Unlock" app icon dispaying on the App drawer after Factory reset.

Yeah, At least not blacklisted.
Yesterday I found another solution and resolved this problem.
My conclusion is it's double fault both Samsung and T-Mobile. It meaning first unlock not processed perfectly and it would have been cause relock problem.
Detail things of this provlem will update soon with timeline and evidences.

My GS7 recently re-locked as well after trying the G930U ROM. It was unlocked via the app after 40 days of service, and worked fine on AT&T for a little while. I recently went back to the G930T ROM and the device unlock app showed back up. It now throws the same error - "Unlock Failed: Mobile Device is Permanently Unlocked". Device is not blacklisted, and I no longer have an AT&T sim to try.

T-Mobile OnePlus 6T OEM Unlocking Option Greyed Out... Why?

Have you not been paying attention?
The T-Mobile version is BL locked until paid off.
Once paid off the IMEID must be provided via a form to get an unlock code.

Do you own it the phone or you're financing?

Good, after you get the unlock code and unlock the phone the option will be un-grayed. Also, if you haven't got the code yet, just try the unlock app, it's likely that'll work.

There is no SIM Unlock code to get on T-Mobile phones,you're either eligible/approved to get the phone SIM Unlocked or not.
When you select Permanent Unlock,it will unlock,reboot the phone,the Device Unlock app disappears & that's it.
Then,if you wish,you're free to OEM unlock/get the token from OnePlus,etc.............

OnePlus 8 T-Mobile Repair Nightmare

Figured I share my repair experience here as OnePlus has set a new low in my book for customer service. Started when I sent my device (unlocked by T-Mobile) for repair last month. I was given the option of repair or replacement but chose repair so I wouldn't have to unlock again. I received it back about a week later but with no documentation as what the repair was (found out through my calles it was a motherboard replacement. I did notice the SN was the same but the IMEI was different. Used it for 3 days and called T-Mobile to have it unlocked but their system now sees my device as a non-T-Mobile phone and they can't unlock it (and they have tried 4 times since Sept 25th). Over the past few weeks I have conferenced on T-Mobile support with OnePlus support in an attempt to get it unlocked and every time I call it's like starting from scratch with OnePlus. Four times now I've been told to wait 24-48 hours so they can hear back from there repair facility, I've made 14 total calls to check status (they have never called me back once). T-Mobile has been absolutely great and were on the phone with OnePlus with me for over an hour. So for know unless a miracle happens I'm stuck with a phone that can't be network unlocked by any carrier. Looks like the repair facility perhaps used a standard motherboard and flashed the T-Mobile firmware on it from what I can determine. If you need service for a T-Mobile device ALWAYS choose a replacement if you have the option)

Rule #1: Never ever choose repair when replace is an option. XDA is rife with people complaining about repair issues with every phone manufacturer. But I think you know that now. Also, I would hardly fault OnePlus in this situation. Its a simple issue of the IMEI not being in the T-Mobile database. Thats not OnePlus' fault. Thats a T-Mobile issue. IT can be added to there database. Verizon does this but for a completely different reason. But ultimately fault is in the eye of the beholder.
Also, to further support my claim think of it this way... T-Mobile (and Verizon) request the bootloader / SIM lock. If you buy the non carrier version from One Plus this would be a mute point. Again, a T-Mobile issue, not OnePlus. If you really want to get technical fault the US Congress for allowing them to lock in the first place. Ok Ok... Way off on a tangent...
Now... Some questions for you...
Have you ran the IMEI against an IMEI check database to see what kind of device it returns as? I would be curious to see. Another way to find out if its a T-Mobile device is to check the IMEI against your last phone. If the first few digits are the same or different will support your claim of the device being different.
Have you tried to tried to toggle the bootloader unlock switch or is it gray'ed out?
Have you tried popping in another carriers SIM just for giggles?
Lastly, have you tried to unlock it yourself by using the built in unlock program in network settings?
If that fails you may want to consider sending it back to OnePlus again for replacement. I can only assume that you do not have insurance? If you do then you may want to check with them about replacement faulting the IMEI as the issue. Might be a hard sell but I'm sure it could be done.

Same situation here, mine was unlocked did a replacement and it was locked and T-Mobile has no record of it. It took me 17 days to get the replacement and every day I checked the status I get told wait 24-48 hours. Now after I got it I'm told every day to wait 3-5 days for an update. Really one plus?

One plus sucks at anything customer service. Can you not do a warranty through tmobile?

Hi, i have the same problem. I was able to unlock my OP8 the moment I bought it. But after sending my OP8 for repair, it was locked when sent back. I got the error "server 255" when I tried to do a permanent unlock.
I contacted Tmobile and they said I need a valid tmobile account, which I don't:
"One of our mobile device unlock requirements is an active T-Mobile account. Since you don't have one you're going to need the get the unlock via a 3rd party company. Our apologies for this."
I have contacted OP 4 times now. They say they'll escalate my problem to the relevant team.
So how did u ppl solve it? Anyone tried the mtd below:

"One of our mobile device unlock requirements is an active T-Mobile account. Since you don't have one you're going to need the get the unlock via a 3rd party company. Our apologies for this."
I have contacted OP 4 times now. They say they'll escalate my problem to the relevant team.
So how did u ppl solve it? Anyone tried the mtd below:

I hate oneplus with a passion I'm 8 months and still going with an issue they keep BS'n me on

Hi, I would like to post an update. After contacting OP support a few times thru chat, they agree to help me talk to Tmobile directly. I told them I can't use the phone, I'm overseas (really, no joke), and I contacted Tmobile but they refused to help.
After waiting for a few days, my IMEI is whitelisted and I was able to unlock the phone. So I guess if you are persistent enough and tell them tt you've exhausted your options, they will help. So I guess they're still nice ppl (kudos to Sophia!)
Hope someone with similar problem can try what I did.

Just wanted to fan the flames that OnePlus is still up to their BS. I sent my phone to repair the back glass after I recovered from unbricking my phone rooting after the Android 13 OTA. When I get it back, after all these warnings signs something was off I realized when I tried to put my unlock_code.bin and it kept failing that they gave me a new motherboard. Luckily I AM a Tmobile customer, but holy heck, what if I was not? Luckily somehow I was able to get in to get the info to request another code to unlock my bootloader even though I'm still carrier locked.

I just had my op8 repaired back with a motherboard replacement so that it can't unlock the sim as I am not a T mobile customer. I used online chat several times and complained about sim-unlock. Finally, after I gave them both old and new imei and strong complain, they unlocked my sim card. Not a good experience, but the result turned out to be good.
