If I have an unlocked G1, can anyone tell me if I root my phone and update to some of the firmwares posted hete (RC33), is it possibel that my phone becomes locked again? I now have RC19 and the phone is fully unlocked, but I'm afraid it can become locked again if I root it or flash it with another firmware. I have enough technical background to do the rooting and flashing as I have expoerience with windows mobile, but this is something new for me. Btw - i totally love the G1 and regret not leaving windows mobile.
The Sim-Lock is in an area of the phone that can not be "flashed' by the user. You are good to go!
Thanks a lot for that !

I have been looking for this answer, as well. I have a brand new g1 that I traded my 3g iphone for. It's unlocked and on my AT&T account with no problems. But I had my iphone modded to the hilt and so of course I want to do the with the g1. That was the answer i was looking for!
Anyone else?
Yes. Please, anyone who has rooted and upgraded their UNLOCKED g1 , share experience. It may seem like a stupid question to some of the "advanced" users
bt remember - you weren't born with knowledge, so share it!
For example - an ulocked Iphone can be locked when upgrading so are you sure that the G1 won't lock as well!
What do you mean unlocked? As in sim unlocked, if so it can not be locked by upgrading software.
If you mean unlocked as in you have access to root. Then yes, but that is why you use JF's firmware.
alright ive got a rooted rc33 and im on at&t, ive upgraded from rc30..
so even when you upgrade you're good to go
I mean sim unlocked
I mean what unlocked means - SIM unlocked. My device is rc19 and came unlocked for any sim cards. I haven't done anything with it yet - root or upgrade and I wanted to ask if it's safe root and upgrade a sim unlocked device.
I was concerned it may become locked again because I don't know anything about the unlocking process on the G1 - I know there is a code that's generated according to the IMEI and tahat's about it but I wanted to know if this code can be erased by flashing newer firmware. I have read the steps described on this site for root and upgrade and I plan to do those with my device but I wanted to gather some opinions first. I hope this topic will be useful to others who have bought the G1 unlocked and are concerned.

youre safe to upgrade and root, ive done both and mine has stayed unlocked..
Ok. That sounds encouraging. I recall that there were more than one ways to unlock the Iphone. Is it the same with the G1 - I know the main way to unlock
it is by entering a code but I also know there are HARDWARE unlocked devices (as the developer edition of the G1) - Is yours only simUnlocked or is it hardware unlocked too? I'm sorry if I'm asking too much, but I don't want to pay 30$ to get an unlock code again.
It's not like the iphone. The iphone is has to be 'unlocked' by hacking the firmware, since apple have never released any legitimate way of unlocking it, and seem to take great delight in re-locking 'unlocked' iphones every couple of months (this is one of the reasons why my iphone sits at home gathering dust).
The G1 has a standard unlock code, just like just about every phone on the market. Once that code has been entered the phone is unlocked permanently. There's no such thing as a hardware unlocked device - it's merely never been locked to a provider. In the same way if I buy a 5800 from Nokia it's unlocked but it's no different to one got on contract, it's just never been locked.
Google don't care much if you run JF firmware or something you cooked up yourself... they give away the source code so you can do just that.
Thanks.
So entering the simunlock code is irreversible process, having nothing to do with the firmware. That's what I wanted to hear. Thanks guys.
Successfully rooted, upgraded to Jf RC33 with multitouch, put apps on SD and very happy now

Is it possible to unlock for free ? Couldn't find an manual (only jtag).
should I risk to buy an locked phone?
This has been covered elsewhere.
Your simlock can be removed by the service provider.
either that or there is a site out there that charges about £20 to send you the unlock code.
Ive just got a G1 off my cousin today and have suffered the same. Luckily for me he is still a tmobile customer and should be able to get the unlock code from them for free.

Thanks for your confirmation (wasn't sure about this).Jtag can also be done (but thats madness)
Just another question:
I've read that the locked version uses different gsm networks(dual band), while the unlocked versions use quad band.
Can an locked phone that has been unlocked use the quad band (with the right radio) too?
Anyway I've bought the google phone
I found that unlocking on ebay is the fastest and the cheapest way of doing this.
BTW: the phone I'm going to buy has already CM 4.6, should I root again after every build I flash (the kaiser builds were always rooted) ?
I wouldnt have thought you needed to root again if it already has the Cyanogenmod on it as i think its already rooted.
im still learning the android stuff!
i do know that within 3hrs of having my (still locked to tmobile) "virgin" G1 i had the Danger-spl and the latest release of CM on it!
ebay i will have to look into as i have discovered that because im in the UK Tmobile will charge £15 to unlock even though my cousin has had this phone since release.

Simlock has nothing to do with the rom, and a rooted rom has nothing to do with the simlock outside of prompting you for the code if the radio firmware tells the rom its needed to proceed.
There is no reason to unroot/reroot besides increasing the chances you make a mistake and brick the phone.
If you want a different rom that's your choice, but it will have no impact on the simlock.

So after flashing a custom rom (phone was already rooted) , the phone is still rooted?
Reroot is only needed when flashing the original image back (if you want a custom rom later) ?
Sim unlock code is best to unlock the HTC G1,But free unlock code is not possible to get for this Model Phone,You need to pay for it,Get the unlock code from the site Superunlockcodes.com/htc/rs12wp8/ and Unlock it.
I have a T-mobile uk Arc that has been network unlocked using Octopus SE.
Unfortunately when I go into the service menu it still says "Bootloader unlock allowed - no".
I though that unlocking it from the network might have changed this.
Is there anyway to unlock the bootloader and/or root the device if the bootloader unlock says no? i tried re-flashing using the namaste guide, but it didn't work.
I really don't understand why this is the case though. What is the determining factor for the bootloader status?
(sorry i know there's a few questions here but i'm so frustrated from having no look in researching this)
Thanks for any help you can offer!
In the service menu if your Bootloader Unlock says no then you cannot UNLOCK it.
The only way is VIA TEST POINT method (which carries RISK of bricking your device) can be done to have unlocked.
You can still HOWEVER root your phone. Cheers mate.
First of all thank you for the quick response.
I unlocked my phone from its network using the testpoint method (using Octopus Box). Is this the same as what you are referring to or is it a method of re-flashing that uses the testpoint?
Thanks!
If you done it correctly "TEST POINT" method your Bootloader should be unlocked.

Hold the menu button, plug in your phone.
If the LED turns blue (fastboot mode), your bootloader is unlocked.

You now have a unlocked phone, not a SIM-FREE phone. Only a SIM-FREE phone that was never sold via a network will come with a unlockable bootloader.
It's why these sell for a bit more (£30ish).

... he's already said he unlocked it from the network. Therefore, he does have a SIM/network free/unlocked phone.
However, SIM/network unlock is completely separate from the bootloader.
If the Service Menu says bootloader unlock is not allowed, you need a paid tool like SE Tool to unlock it.
Perhaps it's a regional terminology thing.
In the UK, unlocked means it was once locked to a network (but usually still with network branding)
Sim-free, means it's totally unbranded, not sold with a contract and not sold by a phone network. ie. totally independant of any phone network.
Only Sim-free is unlocked bootloader.

I agree with you, I don't think they really understood exactly what you meant.
I remember Rikard from the SE Blog when they announced about bootloader unlocking on the new xperia phones. He also said that phones with generic firmware will be allowed to unlock bootloader.
So just because, you have unlocked a phone from t mobile it isn't a Sim free phone.
Sent from my LT18i using xda premium
I have to be thankful that my actual carrier doesn't do sim-lock.
First of all, thank you for your contributions.
So to re-cap, it is a T-mobile branded arc, that is now network free, but not sim free.
Is it possible to flash the phone to make it sim free? Would would using SETools acheive this?

Ugh. SIM and network are the SAME thing: locked to a specific carrier / cannot use a different carrier's SIM card.
The bootloader is different. Generic (unbranded) phones have unlockABLE bootloaders through a FREE process. Carrier-branded phones ALSO have unlockABLE bootloaders but the process is NOT free.
Any bootloader can be unlocked, regardless of SIM/network status. I suggest you watch the video and pay attention to the FAQ.
There is no firmware or software that you can flash onto a phone to SIM/network unlock it. Buy an unlock code or tool credit (Omnius, SE Tool, etc.).
There is also no firmware or software that you can flash onto a phone to unlock a bootloader. Either use http://unlockbootloader.sonyericsson.com or pay to get it unlocked.

Thanks for the answer but CrazyPeter is right. There's a regional terminology issue here that is not not translating.
That being said it does look like SETool is the way forward. I should've checked exactly what result unlocking with Octopus box would have.
Contact Jinx13 who will be able to unlock and open bootloader
I had sim locked three phone he did mine Sunday and it is easy and quick
Thanks cheify009. Heard his name being mentioned a few times now.
If u don't mind me asking, was it expensive?

Although you can still update via PC but not ota as it will brick the phone.

Good morning to all! I have a big question! I have a Sony Ericsson Experia ARC vodafone brand new and comes with android 2.3.4 compilation: 4.0.2.A.0.62, and when connect it via the PC COMPANION tells me there's a new update 4.1.A.0.562, should I update it?
I've seen in many forums that updating the phone slow down the performance and assure me I'll regret of that. the other thing I was thinking is to make a backup of my original rom, but there is some way to make a backup of the original rom if something goes wrong? with the update? thanks
Sup all...
Simple enough question. I've spent many days doing searches here in XDA and google but haven't been able to find a clear answer. Or maybe I didn't look hard enough or understand the responses to others questions regarding this topic.
I recently got an S4 (i337m) from Telus. From what I understand, this is the Canadian model (jfltecan). I am not sure if it is unlocked or not however. I know that I should just use a sim from a dif carrier to test, but I don't have access to one at the moment. No one I know has a micro sim that is with a carrier I could use to test with.
I've installed TWRP and flashed Slimbean and afterward I flashed Paranoidandroid roms successfully if that is some sort of indication as to the lock/unlock state of the phone.
So is there any other way to tell? Is there a method of unlocking this phone other than using the *#0011# method or similar methods that I've tried and do not work. Is an Odin method available?
Thanks
If you got it from Telus, directly, 99.99% it's locked
The only way to confirm is by popping in a SIM from another carrier.
I think it depends on how u buy the device. I think if you get the phone on a contract, its locked, but i think if you purchase the device for full price, it should be unlocked. That's atleast how i think it works.
You are most likely sim locked. There is no Odin method to unlock. You should really just buy a code to unlock. Be very careful using the free unlock methods. After a number of attempts the phone will lock itself so you'll never be able to unlock. Others have also messed up their phones trying it.
Buy a code or even safer, FastGSM.com USB cable method to unlock
I am also on telus, if this works like the s3 unlock you need to be on the stock Rom, can be rooted but must be stock.check the s4 thread to be sure though. You can go back to the custom Rom after you unlock and the phone should still be unlocked
Your phone's boot loader is unlocked. Meaning we can install a custom recovery and install a custom ROM very easily. Your phone is Sim locked if you bought it from telus. This means you cannot insert a Sim card in your phone unless its telus. Any other carrier will not work. You can unlock your phone through Telus. They have restrictions on this however. You're better off buying an unlock code off the internet. Its fast and most likely cheaper and no it does not void warranty. Hope this helps
Thanks!
Just wanted to thank everyone for the replies/info.
My phone was sim locked. I did the easy method of purchasing an unlock code from a local shop here. All is good. I can use the phone on any supported GSM carrier and I am able to flash custom roms and what not.
Thanks again to all for the info. Much appreciated and it helped me increase my understanding on this topic.

Hello,
I just acquired a new 'Huawei Ascend XT' phone which is sim locked to AT&T. I am currently in the process of unlocking the boot loader and rooting the phone.
I was wondering is there any tool available to Carrier / imei unlock this phone after I have rooted it (or may be even befor rooting it)?
Thanks.
I'm fairly certain you just need to change the apn settings manually.. need to do something weird to bring up the option to add/edit, believe it's holding down the tasks button
Without being carrier unlocked, the phone can only be used on AT&T Prepaid, AT&T, or AT&T based MVNOs. These days AT&T won't give you an unlock code unless you use the phone on AT&T Prepaid for 6 months. You can check eBay to see if any unlockers will sell you an unlock code for a few bucks. Only buy from sellers who have a money back guarantee if their unlock code fails.

Bought 2nd-Hand
I would like to ask if there is any way to carrier unlock. I bought this phone for 20$ on offer up. But when I contacted at&t to request unlock they said it has to be used for 6 months. For me that does not work, as I am already with tMobile and bought the XT for a second phone because of the large device support. I actually love the phone, but as is it is just sitting around. If anyone has or has heard of a way to accomplish an unlock please p.m. Me.or answer in forum. Thanks in advance.
Ps. phone is already bootloader unlocked and rooted with magisk 14.0. And latest TwRP.
I'm just having a really hard time finding an answer. I just had a OnePlus 6T T Mobile edition find it's way to me. It's carrier unlocked and Bootloader unlocked and it's running the latest T Mobile version 10 OOS. Since the bootloader is unlocked, can I just flash the latest non T Mobile OOS Android 10 version to it? In other words the US 6T edition? Or must I use the international version? I'm really confused and sure this has to be answered somewhere but just can't find it. Can anyone help and point me in the right direction? I have lots of experience flashing ROMs, but this one has me stumped at this point. Thanks.
I'm no expert... lol, but based on what I do know, I believe these are your steps...
So I'd take a look at this post-
[T-Mobile / Guide] - Full SIM and Bootloader Unlock + Root for locked devices
Background: I am writing this short guide for people like me that want all the info about the T-Mobile 6T unlock capabilities. None of this is my work. I wanted to have a central thread where T-Mobile users can discuss the T-Mobile specifics of...
forum.xda-developers.com
Follow Step 4, and then from that point allow the ROM to update via OTAs. The MSMDownloadTools are basically a fix-all, but set you back in time update-wise.
I do not believe there's a full TMo ROM for the latest updates, but once again, I could be wrong.
You could also use the International Version if you want, that is what I am running now, but if you want root access, I believe getting 11 working has some extra steps/workarounds (so i'm still on 10)
I initially changed to International because of quicker security updates and it works fine, no issues to complain about, but my wife (on TMo stock) seems to get better signal than I do in more rural areas.

Thanks for the input. I have seen all those threads, but the main purpose there was for people who did not want to wait for the SIM unlock. That got them past that and also got them so they were able to unlock the bootloader. I already have an unlocked SIM and unlocked bootloader. So I know I could load up lineageos if I wanted to without doing anything special. I would think I should be able to use TWRP to put the International version on using TWRP. And maybe the US version. But that may not be the case.
It just seems like any work on this device stopped after the above. Of course once you are bootloader unlocked, there may not be need for much more and people may just move on to other ROMs.
Thanks.

The more I search, I guess that it appears there are some privileged partitions. This method you mention gets around that irrespective of the SIM and Bootloader being unlocked already.... Sigh....
