I recently bought a brand new i9505 while on vacation and would like to use it on the Wind network here in Canada. Given that Wind uses AWS bands 1700/2100, the phone did not work out of the box. However, I read this thread that discusses unlocking AWS on i337 phones which have the same hardware as the i9505 (Qualcomm Processor and 4G). The fix didn't work on the i9505 given the difference in model numbers and the QCN files.
Can anyone help me get access to the correct QCN file for the i9505 to unlock these bands? or if you know of another way to unlock the bands, I would really appreciate your help.
Tried already. DIDNT work.

I have the same issue, got phone from 3 UK, i9505 and paplied the process you have in your link and now all other network modes disappeared.
I don't know how to fix it.
I have the exact same problem as the thread starter too. Got my i9505 from HK and would like to get it working on Wind Mobile/T-Mobile which uses 1700 for AWS. I read the same page about enabling AWS bands for AT&T s4 but the model number is different and the QCN file won't work.
Any helps are appreciated
bump for this, I'm in the same boat, any help would be appreciated. I did however, out of curiosity, try the instructions posted in the OP but it messed up my phones radio and couldnt recognize my bell SIM. Good thing i made a backup of my I9505 QCN before flashing the 337_AWS.qcn file, I was able to restore from the back up.

Can you PM me the file as well?
thanks & regards,
~Laudri~
I've been researching this for a while all over the internet and been hearing mixed things at both ends of the spectrum as to whether it can work or not, if there is a concrete answer to this please post or pm me about it, in all honesty this is the main reason I joined the forum , it would help and i appreciate it greatly
Sent from my GT-I9505 using xda app-developers app
Need help as well
I cannot find a QCN file to save my life for this. I have the nv writer reader program and it works perfectly to restore my IMEI. SaHiLzZ, do you have a file that would unlock ATT or TMobile bands? Or perhaps we can develop a guide of what NV items to modify to unlock bands? As far as I know it is a world edition phone and is compatible with all GSM and LTE frequencies. Mine makes calls on a SIM, but no data.

You can count me in on this.
I am also looking to enable AWS on my recently acquired S4 i9505.
Has anyone tried one of those many tutorials to unlock LTE band 4 on i9505? Sorry for bumping this, but I've found some traces here and there, but no confirmation
I tried it and nearly bricked the phone.
Hi all,
I have a Rogers LG G2 D803. I'm trying to enable AWS bands, and to do this I'd like to attempt to restore a TMO EFS backup. I'm doing this because I want my Rogers phone to work on WIND.
If it works, it means we might be able to enable bands that devices aren't supposed to support, like switching between TMO and AT&T bands, or even unlocking them all! But to test if this might work I need a TMO EFS to restore, as just flashing the TMO modem locks down my radio.
Just PM me if you're willing to share one, thanks!

EFS is a Samsung term, not an LG or universal term. What you want is a .QCN (QPST) backup with the IMEI stripped out. I've done this mod on my AT&T S4 and Note 2, so I know where you got the idea from.

Thanks for the encouragement. As it happened, I did use the EFS backup in TWRP and restored a TMO EFS. It didn't work - My phone kind of just refused to cooperate. I have a feeling that between the D801 and D803, there are some hardware incompatibilities. Until a real dev gets this phone and plays with band settings, we won't see this stuff happening.
In any case, I returned my Rogers G2 and ordered a T-Mobile one off eBay today.
Hi,
I just purchased a Galaxy s5 sm-g9006v. This is the chinese unicon Samsung galaxy s5. It's unlocked.
I have a t-mobile sim. The phone works fine but the only problem is that it's only running 2g speeds! and i've been reading and i think it's a problem with the bands the phone is working on.
I've also been reading about changing the firm-ware modem but I need a little help.
My question :
Can I change the bands that my phone is using to t-mobile compatible bands to run hspa+ or lte or 4g ?
If so, is it as simple as flashing flashing t-mobile firmware from sammobile (sm-g900t) to my phone via odin?
And if I can fix it without having to flash the whole original firmware by just flashing the modem (which is 5mb), where can i get the modem for that firmware and how do I flash it alone ?
Thank you
Hello community,
I bought a original Samsung S5 G900F from T-Mobile USA.
Currently I unlock it and is open to all network. This cell phone is selled here in Portugal with all the carriers.
I have put the Cyanogen Mod (latest one) and now appears on the name of the cell G900T.
I need to configure it to get LTE Signal in Portugal (it currently only get LTE when I´m in the center of big cities). Don't reach LTE from all the antennas.
I think it is a problem related to the kernel cause I only root it and change the rom.
Thanks and please help me.
Help please
Anyone can pls upload a modem.img file ATT (H910) , I lost baseband. and my phone lost signal. So please help me. :crying::crying:
