[Q] LTE Bands G850Y - Samsung Galaxy Alpha

Hi guys. I've a question. There's a way to unlock LTE bands on g850Y? I've bought my phone in Chile, but in Argentina LTE doesn't work on the same frec.
On theory, Panama's ROM for G850Y should work in Argentina's LTE frecuency, (band but i'm not really sure to flash, and i'm not sure if i'm doing something stupid and end up with a soft brick.
If that's possible, could someone explain the steps for flashing? (If i have to do a complete flash, or just modem.bin.. etc)
I need a ROM that get's BAND 4 AWS.. is any of this possible?
Thanks!

Same here
I have the same problem, if anyone can help please.

[Q]How to get data working on T-mobile (USA)

how can i make my phone work with T-mobile in Usa, i Have unlocked it but i dont know if i can make it work with Data because i have read that it's impossible to make it work with data on 3g. My Phone is S5830L and i have the kp3 modem from telcel.
You need to see the UMTS frequency that T-Mobile uses, I think it's 1900, so, you need to use the baseband for that frequency.
What rom are you using on your phone? You could try this one: http://forum.xda-developers.com/showthread.php?t=1399917

[Q] How can I get AWS bands back on a bricked Rogers Lumia 920?

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.

##3282# (Or ##3282 call) will present you with a thing that lets you change the bands used for 3g and lte, but it doesn't have the aws band (band IV) for selection under 3g D:

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

Hmm, I guess we're basically just hunting for the Rogers baseband then. If only there was a way to browse the system root of a windows phone device D:

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.

"World phone", also known as a quad band phone. If you want an unlocked phone to work on T-Mobile's LTE, it'll need to support band 4.

Well, I don't think there's nothing much you can do with your phones as the US mobile network operated at different band and your device may not be supporting that band better option for you would be getting a new phone form the vendor other than this no other option can help you much with the problem you are currently experiencing.
Hi. :laugh: today my problem is solved, i can use 3g network all time, thanks all everyboby , so happy :laugh::laugh::laugh:

4G band firmware or hardware?

Hi
bought a p20 lite LX3 in USA, which it's not prepared for 4G bands here in Spain as per link and image information
https://www.kimovil.com/es/frequency-checker/ES/huawei-p20-lite
Does anybody know that if I apply a stock custom rom from LX1 model the 4G bands will work? or it's an issue that it's non solvable through firmware?
Thanks in advance

dont know if using stock custom rom will help, but, with my old p9 , wen i instaled android 8 china version, phone didnt connect to operator, only when i patched it with europe network patch, all bands worked as needed for me, but ofcorse, its european phone with china software, so i guess it is software related not hardware!
