Hey guys. I couldn't get AT&T to unlock my s3 so I downgraded to android 4.1.1 to do the free unlocking method. It worked, but my phone has AT&T apps in it, and when updating it says crap like updating from AT&T server or w/e.
When using ODIN, was I supposed to install the AT&T or the T-Mobile version of the 4.1.1 android?
I figured since it's an at&t phone I have to reinstall the at&t so it doesnt mess up the drivers or anything (I totally made up that conclusion myself).
Also, I don't get 4g LTE now and only get E internet. Do I have to do some settings so the phone cooperates with T-Mobile?
As always, thank you very much for the helping hands.

You're probably going to need to setup the apns for Tmobiles network to work for your phone fully.
It automatically made one called tmobile but I dont know if I have to edit it.
Was I supposed to install android 4.1.1 for at&t or tmobile?

As far as i know you should be fine on the at&t rom, You're just going to need to edit those apns probably.

Well, how about this? I install the T-Mobile rom. Shouldn't that have the proper apns?
Now another question comes to mind. Since this is originally an at&t phone, will installing the T-Mobile rom mess it up?
Anyone? Help plz

Hello everybody,
My Rogers Lumia 920 (unlocked and pentaband beforehand) was bricked mysteriously overnight and I came across the instructions to unbrick the phone. In my NaviFirm search, I noticed that the Rogers ROMs (releases 1232.2109.1242.1002 i believe) for the RM-820 have disappeared as there are many screenshots of them which were posted a few weeks ago. As a last resort, I flashed the AT&T ROM onto my 920 and I have lost the ability to use my phone on Wind mobile and all other AWS networks. Does anybody by chance have an already downloaded Rogers ROM they could share with me? Are there any other roms for the 920 that don't have the AWS bands disabled?
Thanks in advanced!

I just posted links to the Rogers firmware at http://forum.xda-developers.com/showpost.php?p=36686433&postcount=8 .
However, I hate to be the bearer of bad news, but there are reports of the AT&T firmware fully disabling the AWS bands, even if you re-flash the Rogers ROM afterwards. Maybe the posts I've seen are wrong, so by all means give it a try and please let us know the result. :fingers-crossed:
Good Luck!
Wow, thank you so much!!! I'll try it and let you know how it goes.
You have just made my week
Edit: Yeah, the band is still disabled on the Rogers ROM. CURSE YOU AT&T!
Does anybody know how to do a total clearing and re installation of the Rogers ROM then? A bit of a stretch, but hoping this phone won't have to meet Craigslist or something, I love everything about it minus the fact it doesn't work on my network.
Thanks again!

After reflashing the rogers rom did you do a factory reset? I really doubt that flashing an at&t rom permanently disables the aws band even after the original rogers rom has been flashed again. That would mean the at&t rom changes a very secure low level area of the phone and it just doesn't seem that likely or anything I've heard of happening before...

By factory reset, do you mean going into about and reset my phone? If so, yep, I tried it and it didn't help recover the aws band. Is there any way to access the system root of the phone, or am I dreaming at this point? Thanks!

Yeah that's what I meant for a reset. The only other way I can even think of getting the AWS back is possibly finding a dialer code that would let you select radio bands. I want to figure this out too b/c I have a sim unlocked at&t lumia that I want to flash the rogers rom to so I can get the AWS band.

I really have no idea then... But I'm 99% sure after flashing dozens of phones from different companies that the AWS band is not permanently disabled. We just need to find a way to get it back on. Problem is it's probably going to take someone with more technical skills about windows phone 8 (probably searching thru the root directory) to re-enable it.
someone would need to post the baseband of the rogers model and then you can flash the baseband and get your aws band back.
I read somewhere that all the lumias 920 are the same on hardware side, that they only have different softwares and firmware on the inside; rumor has it that if you could get the firmware and baseband that nokia flashes into the dev phones, you could convert any lumia 920 into a dev phone with anything unlocked.

If flashing the att rom to a rogers phone installs the att baseband (which disables AWS) then reflashing the original rogers rom would overwrite the att baseband with the original rogers baseband (should re-enable AWS) so I don't think that is the issue.

The AT&T baseband seems to stick though, maybe the AT&T rom has another file that has no equivalent in the rogers ROM that's sole purpose it to lock out the AWS band. Hopefully we can get this fixed soon, I'd love to love the Lumia 920, but at this rate, my eyes are starting to turn to the 8x.

I don't think the rogers firmware includes the rogers baseband, as the baseband is the one that controls the radios and frequencies of the handset.
One can install a firmware without a baseband and viceversa

The baseband for my stock at&t 920 with the portico ota is 1.0.202075.3. Someone who has a stock rogers 920 that didn't flash the att rom what is your baseband version? (about - more info) Then we need to compare and see what the baseband is on a rogers phone that has lost the AWS band.

I just updated my phone to portico and it seems that I've got the same baseband as you. Can anybody with a stock Rogers ROM post their baseband? After updating, my phone popped up with a new message when I put in my wind sim. It said "Phone mode changes. Your phone is now in GSM mode." I have no idea if you can change modes or anything like that.
Hey guys, I just wanted to jump in here and say that I'm having the same issues. I have a BUILD Dev phone that was bricked -> flashed AT&T -> flashed Rogers and the AWS band is disabled / vanished.
I've contacted Nokia Experts and was told the only option at the moment was to get me a new phone... and I've been waiting for months, lol. I'm thinking that they're going to send me a standard unlocked L920 without AWS bands but that's a bridge I'll cross when or if I get there... I was also told that the repair center did not have the ability to fix this problem and when I asked for the original firmware I was told they (Nokia Experts) did not have it.
Someone HAS to know what's going on here and how to fix it!
If anyone finds a way to get the AWS band back I'm willing to PayPal them $100. Maybe those with more skill will help if we offer financial incentive?
I'm in the US on T-Mobile for reference.
What we need to figure out first is what the baseband is on a stock rogers 920 that has never had the att firmware flashed on it. If it is different then it looks like you'll have to wait this out until nokia comes out with new firmware that has an upgraded baseband and hopefully that brings back the AWS
What about the base band from a Dev device like mine? If the Rogers would work as a reference point then I'd imagine the Dev base band would work too.
There are several users here with them. I can't provide mine because It's been flashed as I mentioned, but I'm currently running 1.0.202075.3 as well as others in this thread.

Is there a way to port TouchXPlorer to WP8? I think it has access to the system directory on WP7 but I've never actually used it before. That might help us extract the correct baseband.
Hi guys,
I need your help please. I bought my htc one m7 a year ago in USA. the phone is at&t branded but internationally unlocked for any SIM card. I went back home to Serbia and phone works fine with my Serbia SIM card but the problem that I'm having is that phone is not updating at all. I still have 4.3 android. In the settings the option is not saying software update but it says at&t software update, just to give you a clearer picture. So I don't know if I need at&t SIM card for it to be able to update the phone or what. Is there some other way to clear my phone like its not bond to any carrier?
Thx

at&t phone can only be updated using ot aupdates if they are connected to the at&t network.
To de-brand your phone you will need to s-off and flash the dev edition ruu.

I'm guessing you want t update to lolipop but can't because Verizon isn't in India? There's Muniz's rooted stock OF1 in the general section.

are you rooted? If not could you tell me which build number your phone is currently at?
As for Muniz, he's a guy who works on rooting our galaxy s4 =)
the latest build for verizon galaxy s4 ends in OF1. it is Android Lolipop, 5.0.1
his instructions are here.
you'll need root to follow the directions.

from the looks of things , this looks risky . i would rather have a unbricked s4 without lollipop thanks for your help. is it possible to root s4 with iroot ?
It's not really that risky.
best way to root kitkat Verizon galaxy s4 is to use towelroot with NC5 build kernal
Verizon's Galaxy s4 is supposed to be unlocked by default, its just rooting is an option just in case you dont like the look of the s4's lolipop. if you want just complete current stock lolipop build OF1 you can download it here and use ODIN to flash, or just use Samsung kies software.
just so you know if you use the sammobile method or kies method to update to lolipop, you cannot go back down to kitkat. Muniz's method with root allows you to return to kitkat builds if you so desire.
by the way what happens when we flash a rom with carrier to a unlocked phone ?

You do realize that Verizon phones are supposed to be GSM unlocked by default due to some agreement with FCC for their bands?
From here
Unlocking a Verizon phone
Even though Verizon uses CDMA instead of GSM, most of Big Red’s devices come with an unlocked SIM card slot. According to Verizon, its 4G LTE devices aren’t locked and, if you want to bring one of them to another carrier, there is no code needed to program the phone to play nice with it.
However, even though SIM-equipped Verizon phones can be used on AT&T, T-Mobile, or other GSM carriers, the phone will need to have roaming GSM radios in order to make phone calls and send texts in the United States. While most recent Verizon handsets will work just fine on American GSM bands, your mileage will vary when it comes to LTE support.
Even though Verizon doesn’t have an online unlock request, you can call 1-800-711-8300 and request a SIM unlock.

sorry for my lack of knowledge . i didn't know that . i bought it from my friend . i thought it was locked by verizon and he got it unlocked for Indian sims .
well, then the choice is yours, you can root your phone and use muniz's method to allow you the option of going back to kitkat if you desire, or just use normal methods like samsung kies to update normally, which will lock the bootloader so you can't downgrade.

thanks buddy you were very helpful . my last question what happens when we flash a rom with carrier to an unlocked phone .
well... if it was one of those international versions of the galaxy s4 like the GT-I9500, then you'd probably brick it by flashing a rom for a carrier version like the SCH-i545. or at the very least softbrick it.
I think unlocking phones is something more hard coded than the rom itself. cause, even if for example you have a att phone unlocked, it still has a att rom, and should be able to update the rom while using an att sim
though in your case, I have a feeling whoever "unlocked" your phone never bothered anything other than change the APN settings to that of whatever Indian carrier you were using.
your phone shoulnt have any problems with flashing an update via kies.
check your build number under settings> more> about phone. if they match any of the PDA here, you're on stock. using network signal info app in the play store can also tell you the build number (build ID) and bootloader.
though if your phone doesn't say "custom" when you boot it from power'ed off, that you're probably on a stock rom with no root

Sew the other firmware is not for 850a will not.
Hello, looking for some help to see if anyone can help me find the firmware of my A526U specifically for AT&T? I have moved my phone over from TMobile where I purchased it from, and am looking to re-flash it to AT&T. Was working fine for a few months, now I'm no longer able to make or receive calls.
After inserting the new AT&T SIM card, the TMobile splash screen still shows up. The Service Provider software version reflects TMobile still as well and I'm concerned that for whatever reason the phone did not fully update after inserting the new SIM. I spent 2 hours on the phone with AT&T support after the store said they couldn't help me. Pulled the SIM card out, restarted phone, put it back in, reset network settings etc. I've searched sammobile and I cannot find the AT&T firmware, only TMobile, Sprint, and TMK. I would sincerely be greateful please if anyone could help me by pointing me in the right direction for the firmware for this model phone.
AT&T doesn't make their firmware available publicly - for any device. I have a source who can get me Samsung firmware for any USA device - even AT&T. But he charges me for each one
I appreciate the quick response! Is there any option I have here? Could I try flashing a "U1" firmware to his phone then? He's currently on A526USQS4CVA6.

If I'm reading that correctly, I should be able to correct? If so, how can I tell if the version I'm downloading is "downgrading the bootloader"

1. Yes, you can try flashing U1 if you want
2. You can't "downgrade the bootloader" - Odin won't let you.
3. In A526USQS4CVA6, "4" is the position of the bootloader level/revision/binary. Make sure that whatever U1 firmware you download also has a 4 in that spot and you'll be fine. (Or just get the firmware from Frija or one of the other similar firmware download tools, because those throw you whatever the newest version is automatically)

My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though. Same sim card.
I would contact AT&T advanced tech support as there may be an easier way.
4G VoLTE needs to be enabled in hidden settings.

The U is the AT&T variant vs the U1 which is the unlocked variant, correct?

Yup. But OP has a T-Mobile model that they moved to AT&T. There's also no guarantee that a Note 10+ will work the exact same way as an A52. You're also running 3 year old firmware, while OP is fully updated.
So i don't see the correlation.

The old firmware works fine on 4G VoLTE... that's likely not the issue. What is the issue is it wasn't running on 4G VoLTE so it's likely the settings and sim card need updating not the firmware.
Hi All, thought I would provide an update... After spending hours on the phone with AT&T support this week and being frustrated with the AT&T store, I decided to proceed forward with flashing the U1 version. What started this all was last week my son could no longer make or receive calls on his AT&T A52 phone (we ported it from TMobile September 2021). The store and AT&T advanced tech support said there were issues with people's BYOD devices, even though the A526U and A526U1 shows on the supported devices list. The store rep said he's been getting people in left and right that can't make or receive calls, and all they can do is upsell customers to an AT&T branded phone.
SO... my son's phone was on A526USQS4CVA6. Startup screen showed TMobile still, even with the AT&T SIM card in it. I proceed to flash the A526U1OYM4CVB2_ATT that I found from Sammobile. Was hoping someone had just the "U" version but I couldn't find this anywhere. When doing the flash, I used the Home_CSC file (I had to download a patched version of ODIN as it was stuck as setting up connection) and when it finished it would just keep going back to the download screen on the phone and I freaked out. I did some more research and decided to flash again using CSC instead of Home.CSC (I did a backup using smart switch on my PC luckily). This WORKED! I'm guessing because the software version he was on was different than what I was trying to flash too so maybe this is why I needed the CSC for a clean flash (there was no user data file that downloaded from SAMMOBILE).
Now, calls are working on my son's phone again! AND his service provider software version now reflects ATT vs TMB! Man this has been one heck of a journey lol. I've seen numerous forums on google of people having the same trouble with me, their BYOD devices not working. Seems a flash of U1 worked for me, so hopefully this helps others out there!
