Need reccomendation to buy unlock code for ATT N900A - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I have an ATT N900A that I want to use on US Tmobile but I cant use the chainfire regionaway method since I am on baseband MJ5.
Can anyone reccomend an unlock seller for this phone?

Unlockunit.com - they offer a 50% refund if you post a YouTube video of unlocking

What did you put in dialer to be able to input an unlock code?
Bump.
I'm having this issue too.
Disabled the unlocking app, and have no where to enter the unlock code.
Whenever I reboot, with the foreign sim, it says: This device is eligible for auto unlocking through the sim unlocker app.
I hit close and have no where to enter a code.
---------- Post added at 03:21 PM ---------- Previous post was at 03:12 PM ----------
With an active T-Mobile sim inserted, I was able to do this:
#7465625*638*#
It asked for unlock code.
It said accepted.
Rebooted with new AT&T SIM, still asks for network unlock.
I wanna unlock the device to use here in Brazil with brazilian carrier sim card. Sugestions? I have a G925T.
I already bought a unlock code on eBay, just waiting for the code to test it.

Where did you get the code from???
Has anybody tried flashing an international firmware to their g920t to try to get the sim unlock code to take?

That's a good idea I think I am gonna do that now.
BTW if I do this, then we find out if we can flash international firmwares on the G920t
EDIT: Didn't work failed
I got the unlock code from a seller on eBay. Was $25

This whole issue started when tmobile started testing the Samsung Galaxy Avant (SM-G386T). I had bough 13 of these phones (I'm a reseller) but unlock code did not work. But this same phone was released on Metro PCS that works on Tmobile networks. The model numbers was same with Tmobile except the roms was different. What i had did was flashed the Metro PCS roms entered the unlocked codes from 3rd party (It worked)
Now with the S6 and S6 edge, these phones are not yet released on Metro PCS and i am not sure they will even release them. But if they do i think it will be good to try. I am not sure if the international Roms will work since as there might be a slight hardware difference.

I tried that but it will not accept the code because of that unlock app. Do you have a link to the Metro S6 rom you flashed? Please can you share? I have looked on sammobile but could not find any s6 rom on there just yet.:cyclops:

Switching From Galaxy S6 cricket to at&t

I have seen the forums that its easy to shift from cricket wireless firmware to at&t but the problen is i have saw people saying that you will lose your unlocked sim or it will get relocked by the carrier as it upgrades.....is that true?
Also wanted to know if someone can post a tutorial or something like that... im currently on buildnumber g920aztuu3boj6
And im looking forward to upgrade to MM
It would be great if somone helped me out?

Link is right above....
Yes, it is easy. Only benefit to do it at this point is better android security updates in the future...right now ATT and Cricket are on same android security update.
Downfall is, I have not found a way to go back at all. You get ATT bloatware. Some of which it terrible....you also don't get OTA updates. and yes it relocks your GSM Sim unlock....(However, all you need to do to fix this is call Cricket again and get a new unlock code if you do not have the previous unlock code and reinput it.)
At this point however I would not do it, and wish I could go back.

Once you physically do an unlock on a Samsung S6 device(*putting another sim in and booting up the phone and inputting the code.) then the device will remain unlocked and you can flash threw odin, or backups or factory reset the phone without losing the unlock. Only way I know the lock can be re-enabled is if you do an emergency factory recovery on the phone or you have the phone serviced(in which they do an emergency factory recovery on the phone.) and I don't even know if you can force an emergency recover in Smart Switch anymore like you used to be able to do with Kies.

Anyone flash the unlocked Note8's firmware on T-Mobile?

Wondering if anyone has been able to flash the unlocked firmware onto the T-Mobile Note8.
Previous to my Note8 I had a Galaxy s8 which was flashed with the U1 firmware using Odin...
I looked and didn't any post/thread about this, however my apologies if I missed it -- if said thread/post exists where it explains how-to I'd LOVE to see it.

No bloat from carrier, no boot sound, "stock" Samsung. You'll lose Wi-Fi calling depending on your carrier, you'll lose rcs, 256Q, and 4x4 mimo.
Overall I found the tmobile firmware better with just disabling the bloat through adhell.

For me that's too much to lose.
@all I appreciate the responses. I'm gonna try it I'm about an hour and report my experience.
I can't find much T-mo bloatware on mine. What else besides T-mobile, T-mo TV, visual voice mail and device unlock is there? I think carrier IQ is gone for good, anything else?
Will I trip Knox if I flash the unlocked firmware on my T-Mobile? or will anything change in the download menu showing unofficial status?
it will not trip knox and its reversible if you don't like the unlocked firmware. I went back t mobile firmware and used bk disabler to disable the bloat and crap running in the background. all in all you'll have about an extra GB taken up on internal storage which isn't much on a 64 GB device IMO.
With unlocked tmobile N8, if I flash unlocked fw, then device should work on Verizon?
hello - i also have this question. (sorry noob here).
I got my tmobile note 8 unlocked by paying off the the pending amount and followed the Tmobile's device unlock procedure. But even after that the phone did not work with Verizon's network.
Reading BlueFox721's post for carrier switching (link)
Is my understanding right that, first I have to follow the Carrier Switching procedure and then I can choose between 2 options
(opt 1) flash a specific carrier FW or
(opt 2) i can choose to flash the phone with the unlocked firmware.
Am i also right that flashing the phone with a carrier specifc FW provides some advantages that are specific to that carrier's network setup (features such as wifi calling, 4x4 mimo) and that also adds some of the bloatware from that carrier.
appreciate your help in advance.

Yes
Dumb question. If the device is carrier locked, say to tmobile, will flashing unlocked firmware on it unlock it as well? or is it based on imei?
Nope, unlocked FW won't sim unlock the phone. And if you want to use Tmobile's unlock app you need to use it with Tmobile stock FW.
Doesn't unlock firmware support 256 qam and 4x4 mimo? It has band 46

De-Brand a G977P, Sprint S10 5G?

Just got the phone, unlocked it, works fine on T-Mobile, but I was wondering if we can debrand this or rebrand to another carrier like most G9xxU phones out there. I know this is a P and probably isn't simple, but has anyone tried yet?

what csc are available on your device/firmware? for example my N976V has VZW and GCF.. i switched to gcf and its basically unbranded.. at least in my case..
problem with the carrier specific models they might have slightly dif capabilities such as network so putting csc on that doesnt go with the device might not work right

so u took full tmo firmware for a g975u and flashed it to g977p without unlocking the bl or anything?
can u take a pic of ur about phone and software info and post it so i can see what its reading as?
this is very interesting since it would mean that the regular U versions are signed with same keys as the 5g sprint version which is unlockable.
also, did u flash everything? BL AP CP CSC etc?
I flashed the G977tuvs2ash_8_tmb_[www.unlockguy.ca]. I have since paid my sprint bill, refreshed the sprint firmware, and it is good as new, with the OEM unlock button now showing up. You want me to try it again without enabling oem unlock and see what happens?

Well it has only just been released, and verizon is notorious for their security
So can someone summarize what can be bootloader unlocked? Not sure why there is no thread dedicated for this, maybe it wouldn't be asked 1,000 times over and over.
SM-G977P: Sprint 5G, can be bootloader unlocked like Exynos and other Android phones easily and rooted.
SM-G977T: TMobile 5G....????
SM-G977U: Verizon 5G, not unlockable or flashable?
SM-G977N (Exynos): ?

How about the note 9 through tmobile?
Better size, micro sd card slot and headphone jack. Don't know what Samsung was thinking.
Anyone know the model of note 9 tmobile sells and if it's bootloader is unlocked?
How about the note 9 fron tmoble?
Earphone jack, Micro SD card slot, great size. Thru say unlocked bootloader.
Anyone confirm that tmoble note 9 is unlocked?
