I just received my sim unlock code from AT&T. Going to unlock the device tomorrow with a project FI sim. Should I then flash Samsung's s9 unlocked firmware? Or is it not compatible with AT&T hardware?
Thanks.
If you unlock it (with the help of AT&T), why would you mingle with flashing the firmware? I mean, there's no point in doing it. Your phone will work with any other network, so you don't have to do anything else with it.

In my research I read that firmware/os updates, such as monthly security updates, will not download/install without an AT&T sim card installed in the phone. So, if I were to use the phone with another carrier, I would be forfeiting any and all software updates.

Yes, that's right too. It's all down to how comfortable are you with these changes

I have a Canadian Bell S3 i747m which broke and I got some random guy to fix it for me. He frustratingly ended up installing a ROGERS circuit board(or so he says) without bothering to check the fact my phone was loaded with Bell bloatware or just asking me my carrier.
I now need to unlock the SIM in order to use it properly and I just want to be sure I have the correct information and I don't end up paying for an unlock code that will not work since I didn't provide the proper carrier.
My SIM card (not sure if that matters): BELL
My board/IMEI: ROGERS (Apparently)
I wanted to determine which carrier I was tied to but I see 0 bloatware in my phone which makes me think the guy is wrong/lying and it's not actually a Rogers board. Is there another way to determine which carrier my phone is tied to?

The carrier doesn't matter. Once unlocked, it's unlocked for every carrier (unless it's unlocked by code).
You could go check the APN to see which carrier it's from.

Oh really? I was looking at the gsmliberty site for unlocking and it asks for a carrier. I can't post the link since I'm a new account but here it is split:
gsmliberty(dot)net/shop/samsung-galaxy-s3-unlock-codes-p-3528.html
I then went into their Terms of Service and it specifies that if I provide an incorrect carrier and the unlock code doesn't work then I won't get a refund. Does this mean this site is BS and I should avoid it and find another?
EDIT: Oh I see you added info about checking the APN. Don't know what that is but I'll Google it. Assuming I find it should I still avoid gsmliberty or should I give them a shot?

I went to Settings > Connections > More networks > Mobile Networks and it tells me this: Insert SIM card to access network services
EDIT: Ok I finally found the AP and CSC by dialing *#1234# and then comparing it to sammobiles firmware to find out which carrier it is tied to. Still worried about the fact I get the SIM error above but hopefully that will go away when I attempt to unlock it

Umm I though you'd have access to it w/o a sim card.
I'm not sure how else you could determine which carrier the motherboard is locked to.

I just ended up editing my last post a minute before you posted this. I did determine the carrier and it is in fact Rogers. I was planning on just getting an unlock code through a website. You mentioned that means it will only be unlocked for them which I'm fine with but I'm just concerned about the fact I have a Bell SIM. Will that cause any problems with the unlock process or future dealings with BELL?
Actually I have a better question. Can I just put Bell's firmware on my phone instead of Rogers using Odin and then get an unlock for Bell and theoretically I'll be back to where I was?
What bootloader is on the phone? If you have the 4.3 bootloader, you'll have to buy an unlock code. If you have the 4.1.1 bootloader and you are running a stock ROM (doesn't matter about the carrier), you can use the free method to unlock it. If you have the 4.1.2 bootloader, downgrade to the Rogers 4.1.1 ROM and unlock it using the free method.

I'm running 4.3 so I know I need an unlock code unfortunately. I have a Bell SIM card but have Rogers firmware. The site I was looking to buy an unlock code from asks for my carrier so I presume I need to use Rogers. Will that be fine or am I able to just throw Bell firmware on my phone and buy an unlock code specifying Bell as my carrier?
I am not sure of you can load the stock Bell firmware and change the phone so it is locked to Bell. If this were the case, owners could switch carriers by flashing different firmware.

Unlocking is permanent and unlocks to every carrier. Knowing which one you're locked to only matters to get a unlock code, after that, it's free for all.

Gotcha, so there's no point in flashing Bell firmware at all. I just need the correct one for getting an unlock code in the first place. Thanks for helping a noob out.
Hello all,
I have an LG G8 on November firmware (I think) on Pie, not Android 10. I am looking to update to an exploitable firmware, but don't want to pay for AT&T service.
How do I go about doing this? I can see I can buy AT&T sim cards on eBay, but not sure what to go with.
My phone is also locked AT&T, but it looks like we don't have an unlocking solution yet. I know putting red pocket on the phone doesn't give me updates and still makes it so AT&T's unlock portal doesn't see my phone IMEI.

Unfortunately, there isn't really a way to do anything right now since the pie firmware isn't exploitable. The only thing you can do is try to call at&t tech support and have them add your imei to the update database

It looks like LG installs updates incrementally, so by purchasing an AT&T sim I think I can get to the exploitable firmware just by doing a couple updates. I'll post back once I get the sim
Has anyone flashed the retail/retus image from mirrors.lolinet.com on this to use with a different carrier? Boost requires you to use their services for 12 months before you're eligible for network unlocking
It will most likely work
I can confirm that flashing retus to the Boost variant works fine to unbrand the device.

Worked fine on the Boost network when I tried it.
Flashing RetUS firmware
Earlier this month I picked up a Boost Moto G Fast. I was disappointed to find how much bloatware came with it and that it doesn't include WiFi calling. I have not unlocked the bootloader while I decide if I want to keep this phone or not.
I just downloaded RetUS firmware from lolinet.com.
Do you have instructions for flashing this firmware? I couldn't find any for this phone so I was planning to tweak the instructions for flashing the Moto G7 series at https://forum.xda-developers.com/g7-power/how-to/guide-moto-g7-power-supra-flash-to-t3927138
Any idea if I can flash this without unlocking the bootloader? I'm assuming the factory image is signed by Motorola and should be accepted by the bootloader without unlocking.
Do you have to wipe userdata after flashing or can you keep your apps and data intact since the firmware should be the same version?
Does the RetUS firmware support WiFi calling?
I'll probably be able to answer these questions myself soon enough but I thought I'd ask first.
So after flashing the retus firmware myself on my moto g fast from boost mobile, inserting my active SIM card from tmobile did not work and the uicc said it's still lock to sprint network so I don't believe we can get network unlock simply by flashing different firmware on this

Nope. I bricked my phone trying. Do not attempt to flash anything without unlocking the bootloader first.
Flashing the the firmware doesn't remove the carrier lock. Currently have mine on RETUS stock and it still says it's on the Sprint network and the software channel says "Boost."
Unfortunately it doesn't look like there is anyone out there able to unlock these devices either.
I also been trying to work with this...no avail. So far:
Unlocked bootloader since unboxing in December...thanks Motorola developers..
I lost count on how many times I bricked this phone.... probably 7..
I sent it over to MX last month to see how it behaved. They couldn't activate. "Phone is too new'...WTH..
Now is sitting on my night stand. With games apps, Kodi...just waiting to be flashed again. PS: I hate you boost mobile!!

I switched away from Boost back in December and recently switched back, so now I can answer this question. No, the RetUS firmware does not support WiFi calling.
I got a new phone, the LM-G820UM AT&T version. I followed this guide: https://forum.xda-developers.com/t/tutorial-crossflash-bypass-opid-mismatched-error.4345963/ to flash the stock firmware. With my SIM card in it says "network locked", it doesn't prompt for the unlock code. I have the unlock code and I've tried the various unlock commands (2945#*71001# and 2945#*20001#), but nothing comes up when I do these. Do I need to get it back to the AT&T firmware to be able to unlock it? If so, how can I do this?

wow, yeah, that's unfortunate. First, yes, it's the at&t firmware that the unlock code works with, not any other firmware.
second, at&t doesn't make their kdz available, so you have no easy way to get back to their firmware.
you might get lucky and find someone who has backed up all their partitions from at&t. Then u would flash ea one back via qfil.
Important lesson: don't buy a locked phone. if u get a locked phone, don't to anything to the firmware until u unlock the phone.
cheers
@AsItLies would this phone work in it's current state with AT&T?

To the best of my knowledge, no. At&t is one of the carriers that has restrictions for their networks. Last I read (have never used them personally), they only allow phones that have their IMEI (they check that), and it's using their ROM, to access volte and vowifi.
so, would it work? yes and no. Volte and Vowifi may or may not be important to you.
Additionally, I'm absolutely no expert with at&t, so u might just try and find out, my info could be outdated.
Hi,
Can u pls let me know if it is possible to flash generic firmware(like firmware from Google Store's Pixel6 pro) on Unlocked ATT Pixel 6 Pro?
The reason I'm asking is, because i have ATT specific functionality on esim addition that prevents me to add Non- ATT esim.
Thanks
I would refer you to this link https://developers.google.com/android/images
@mindseye0803 If by unlocked you mean the bootloader is unlocked, then yes. If you merely mean it's carrier unlocked, then no - not unless you are able to unlock the bootloader as well. Keep in mind, unlocking the bootloader will fully wipe your phone including internal storage so be prepared.

Yeah, since it is carrier unlocked and ATT one, i can unlock the bootloader. Do i need to unlock bootloader before flashing generic firmware? Can i lock bootloader back after flashing generic firmware?

When you say generic firmware, you just mean the official Pixel firmware Google provides, correct?
As far as I know, all the carriers use the same official firmware, and would be the same as Google provides for manual flashing.
Yes, you need to unlock the bootloader before manually flashing.

Yeah, i know currently there is just same official firmware but initially there were individual versions. The leftover from individual version is that while adding esim , it shows ATT specific messages and might be limiting the additon of non ATT esims.
Nothing can be "left over". If your phone has been updated to 12.1, then you have the universal/only factory firmware build available. But note that there ARE carrier specific packages installed in that firmware, the specifics of which will be selected based on whatever criteria they've decided on. Might be whose sim card is installed, or could be some hardware model code.
In other words, the procedure you are attempting to follow will not yield the results you're looking for.
Are you certain that it is SIM-unlocked? If you put in a physical sim from a different carrier, does it work?

Ok, i was looking at options as I'm having trouble porting to US Mobile. Since this was sold as ATT branded Pixel 6 pro, carrier specific packages installed in the firmware based on hardware model code makes more sense.
