Hi guys,
I have a Note 4 on ATT. Im wondering if SIM unlocking will affect the way my device works with my provider in any way, like my updates, or the phones OS or anything. For example my phone automatically downloaded this new lollipop update, but if my phone was unlocked would it update the OS automatically?
Also I was going to buy a code from cellunlocker, is this a good choice?
Thanks!! BTW I am a noob and this is my first post on XDA ;D

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
Hey guys,
Saw a very good deal on ebay india, the seller is selling an unlocked version Note - 3 T-mobile (US), so it can work on Indian GSM carriers.
Now, if you see the description: it mentions:
"The OS Software is Unlocked to Work with all GSM SIMS.
You are not supposed to Update the OS Software as Unlock code is applied to it"
2 quick questions:
1) Can you help me understand what does the seller mean here? The device will obviously be running on JB, so i wont be able to update it to the officially released Kitkat? Will manually flashing a firmware from say Sammobile, revert the unlock code and make the device useless?
2) Buying a US phone for Indian use.. Will i miss out on any features? or will it be a problem in any way??
Please help me out guys
Hi guys,
i've got an oportunity to buy a SGSN4. It comes from USA with the AT&T simlock. Is it possible to install a custom rom on this (i dont care about the warranty) with european language? Is it possible also to unlock this phone to use it in every network?
Waiting for your reply, thanks a lot
The att Note 4 has a locked bootloader. Only a limited root is available currently. It resets every reboot and supposedly disappears randomly between reboots. A permanent root is still trying to be obtained, but it isn't clear as to if it will ever be obtained or not.
No root means that you can't install ANY roms or kernels. There aren't even any for the ATT Note 4 because we don't have permanent root yet.
You CAN unlock the phone though. I don't know how personally though, but it can be done. Go to the ATT Note 4 forums and read through there.

Hello Guys, NEWBIE HERE<NEED HELP WITH ROMS AND CARRIER UNLOCK OVERSEAS FOR THE 350T>
So, heres the deal, I'm currently abroad, so I've got no idea of, if I can flash the Global Unlocked version of the Stock UNLOCKED rom for this variant of the GRAND PRIME.
Since it is the tmobile variant I did had my doubts when buying the phone, but I got it Dirt Cheap, either way i'm stranding of path, tried to unlock with preinstalled tmobile app, checked the imei on the tmobile - us database to see if that was the problem, not reported lost or stolen anywhere, so I figured, what if removing the preloaded apps that interfere with region lock of sim card reader locking, might help me?
Therefore, my question PLEASE HELP ME lol, its the only phone I have on me and need to use it here.
Regards.

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.
If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??
I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.
...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool
