Going away, wanted to unlock by Rogers Samsung S5 so I can use a local sim card. Bought an unlock code on Ebay, but it was not accepted. Now I'm doing some reading, says that phones with customer ROMS sometimes have trouble with legitimate unlock codes.
So if it's true, I think I need to go back to stock and try. But I wanted to see if anyone had any experience doing this, if they think that customer ROM is the issue. Also do I have to just go to stock, or also stock recovery, and what about bootloader, does that have to be changed back if I've installed an updated bootloader?
Thanks a lot.

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
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 guys,
About 22 months ago I grabbed a UK Note 3 (n9005 iirc) on the O2 network and loved it to bits. I requested my unlock code in early April, received it and proceeded to grab a new phone and passed my old Note 3 onto my Dad.
The Note 3 had it's bootloader unlocked, rooted, custom recovery flashed and running SlimLP and is till pretty great.
So my Dad pops his Three SIM into the Note 3, it asks for the unlock code, he puts the code in direct from the email I received from O2 and... code failed, unlock unsuccessful. My Dad being my Dad, asked me to input the code and nada, no go. O2 sent me a new code today after I spoke to them this morning and informed them... that new code is exactly the same as the old one that didn't work.
I checked the IMEI number against the one in the email and they match perfectly.
Could the fact that the the bootloader is unlocked, the phone is rooted, there's a custom rom on and/or a custom recovery installed be affecting the unlock code? My Dad has everything else working to his satisfaction on the phone all except this whole network issue.
At this moment in time I am quite frustrated that despite having the code it's not straight away simple and working as expected.
Any assistance would be most welcome.
The bootloader has never been locked on the phone afaik.
The unlock code needs to to be entered using a stock Samsung dialler.
I recommend flashing back to stock, sim unlock, flash back to a custom rom.

I'm sure the bootloader was locked as it triggered the void warranty bit but it's been so long ago that anything could have happened.
SlimLP uses the stock dialler for Lollipop anyway but it's no pain to flash the phone with a stock rom (does it matter if it's an O2 stock ROM or can it be a stock Lollipop Rom?) and give that a go.
Personally I use PixelPro dialler which doesn't seem to take over the phone part like it used to, only the dialler side.... But that's by the by.
Knox and a locked bootloader and two different things.
Knox is present in almost every Samsung android phone running 4.3 or higher. It is Knox that triggers the change from 0x0 to 0x1.
Locked bootloaders are present on phones from att and Verizon. There could be others but these seem to be the most common. Att and Verizon note 3 bootloaders, once locked, have never been successfully unlocked as no one has been able to find a working exploit.
When I say stock dialler, I am referring to the stock Samsung dialler.
Flashed back to a 5.1.1 stock O2UK network ROM, entered the code and voila.... network unlocked.
Thanks for the assist.
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.
Bought "Unlocked" phone, has sprint branding, seller insists that's how Samsung works
Hi everyone, I bought a Galaxy S10+SM-G975U (same model that all 4 major US networks use) that was sold as "Unlocked" without specifying that it is Sim unlocked, Network unlocked, or Factory unlocked. Most of the time unless a seller specifies which unlocked then it means the phone is Factory unlocked, I gathered this from 9 years of buying and selling Android devices so it's not just a guess.
When I got the phone Sprint OMADM pops up and tells me I have an incomplete activation, "about phone" told me it was Sprint Network Unlocked; after a week it now says unknown under "Brand" in the "status" section.
The seller said that when you buy a factory unlocked Samsung phone and put in a network sim card that Samsung then loads the branding (bloat in my opinion).
1. Is this true that Samsung could have loaded Sprint OMADM?
2. If true can I remove it so that I don't have to "Force Stop" it after each startup?
3. Is there any piece of software or database that I can look up the origin of this phone so that I can either change my eBay review of the sale and apologize for my mistake, or affirm that indeed the seller failed to disclose branding that he knew wouldn't go away when a buyer puts in an ATT simcard such as I have.
I've read one single thread by a user and not a Samsung official that claims that you can pop in a network sim card and then restart to change some software but I have not found even one more thread mentioning this phenomenon.
My background:
I've bought factory unlocked my Moto Pure X and a OnePlus 5 and neither did any ridiculous **** when I switched networks, so that's why I doubt this claim.
I bought a AT&T branded one for use on TMobile. It kept popping up errors. I flashed the unlocked firmware and it works great. I get unlocked updates and everything. You'll need to look on here but there's a walkthrough somewhere. But there are a few advantages for running the carrier branded version so you could flash the AT&T firmware instead. I wanted less bloat so I went with the unlocked one.
Think this might be the thread:
https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
That said after I did all this I did read there was going to be a update to the firmware which would do what you described.... Switching firmware based on the sim card. Never seen it happen on mine still on unlocked unbranded firmware. Maybe this phone is running old firmware prior to the update that implemented this?
not normal. LIke you, I purchased an 'unlocked' phone and when I powered on, it was a Verizon phone. I popped in my TMo sim, and it worked OK, but I would get the annoying Verizon popups reminding me that I'm on on their network. I installed the unlocked firmware and it went away.
But there's more: when the phone had a problem, I sent it back to Samsung under warranty (still unlocked) and when it was returned, I just installed the original sim and powered on. Now it seems to be a TMo phone, and when I look at the phone's software version, it shows TMB/TMB/VZW. It's been receiving OTA updates and I've disabled bloatware, so I'm OK with it.
Just to be clear I'm not going to flash anything. I'll just turn around and sell it. I need a stable phone for work and I used to mess around with flashing different roms and while it was fun it was a frequent activity and I don't have time for all the annoying trouble this phone has been. Thanks everyone.
Flashing rom is different from flashing a stock firmware. In your case the only way to be completely off from the previous network you are getting the notification from is to flash a G975U1 or G975U stock firmware which is unbranded or your network branded respectively and you are good to go. I switched my yesterday and am okay ?. I will be happy to assist should you change your mind
