Does software or hardware determine a modem? - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello, I have a Sim unlocked bell Canada note 3 and an planning to rent/borrow a NTT Docomo Sim card from a friend in Japan for use while on a trip in Japan.
I have a stock firmware and modem and am wondering if I can flash another modem to gain access to the NTT Docomo spectrums because right now as is my phone will only be and to access the UMTS 2100 spectrum.
Technical info
Bell Canada stock note3
LTE: 700/850/AWS/1900/2100/2600
HSPA/UMTS: 850/1900/2100/AWS
NTT Docomo spectrum
LTE: 1700/1500/800/2000
UMTS: 2100/800
If any of my facts are incorrect please advise.
Thank you.

I think what I'm wondering most is I'd modern hardware is what locks frequencies or if it's all software and ask it takes is installing student drivers?

SM-N9005 variants have completely same hardware but different software (firmware)
so if u have problem with modem u should flash another rom that 1. compatible with ur device (for N9005) 2. compatible with region.
:good:

I am not entirely convinced that is a good idea - modem files are now notoriously difficult to write with Odin on Qualcomm devices. You should also look into the US threads where I believe there are sensible bounties for making one model of phone to work on the frequency of some other carrier, and none of those being claimed should suggest things are far from simple.

I can't find Canada Bell S8500M firmware anywhere! Need help ASAP!

Okay here is my situation. I have a Bell Canda S8500M phone that I flashed with S8500XXKF2_Full_SHP_sYCO firmware but now lost my UMTS 850/1900 bands so no more 3g signal =( I only get edge. I looked all over the web and can not find the S8500M bell canada firmware anywhere!! I found the Latin America firmware S8500L S8500LUHJL1 that i flashed and got my 3G back but Kies wont let me log on to Canada Samsung appstore anymore.
1)Is there a way to flash my phone with a European firmware while maintaining my UMTS 850/1900 bands from my now S8500L?
2) Does anyone have the original Canada s8500M firmwares??
3) Can I flash part of another Euro S8500XX firmware but keep my 3G bands?
4) devs can you implement a North South America 3G friendly hybrid firmware?
Any help or suggestions will be highly appreciated.
1)you can use the European firmware and get 3G signal too by flashing the whole European firmware except amss.bin (contains modem config) use the one from S8500LUHJL1
2) Don't know where to find those
3) if you mean by the bands 3G then it is same question as 1 with same answer
4) i am not a developer so i don't know if they can
Best Regards
Thanks for your response I will give it a shot and see if it works to flash the Euro firmware without the amss.bin.

I flashed the modified S8500DDJI2 on my phone without the amss.bin file and it worked! I still have my 3G connection and hacked firmware!! =) thanks a million!
Has anyone had success doing the above (keeping the amss.bin file to retain phone's frequency band) while flashing with a Bada 1.2 firmware?
I too want to keep my phone (8500T) 850/900/1900/2100 compatibility.
I have tried flashing S8500XXJID (Euro 1.2) while maintaining my S8500L amss.bin on my Canada Bell S8500M and no luck. No go on the 3G on 1.2 BADA for 8500mhz/1900mhz devices. Maybe a DEV can help implement this in a Hybrid 1.2 firmware with those bands supported.

I9505 on T-Mobile USA

Hello
I'm thinking of buying the international Galaxy S4 i9505 and use it on T-Mobile here in the USA (rather than the T-Mobile m919 variant) ...I am aware that i9505 doesn't have HSPA on AWS band and that's fine because most of my area has T-Mobile LTE which works on the 1700/2100 MHz band (band 4)...
Does anyone from the USA use i9505 on T-Mobile and get LTE ?
Another thing, is it possible to flash m919 radio on the international i9505 to have the lacking LTE bands if any ?
A note : according to gsm arena,i9505 has APQ8064T but couldn't find what chipset the T-Mobile m919 has...If they use the same chipset it would be likely possible to interchange radios between the 2 I suppose...
Any ideas are welcomed..
Thanks
I am in same situation.
We need answer about this From the user or developer who has Experience with this case.
Best Regard to all
any help???
I9500 is the international version, i9505 is the US version

The is not what we want to know.
Will m919 modem work on i9505 ?
It is not wise to flash another carriers modem, but yes, you can.

Recovery, go get the modem you want from tmo forum. and flash it, I do not think it is a good idea, but if you feel it is needed. So be it.
Thanks for the Thanks.
DO NOT flash modems. Flashing modems to enable frequencies has NOT worked on S3, Note2, S4 i337. Don't do it.
"You don't think" doesn't mean "it's not possible" or "a disaster will happen"
I used my skyrocket on T-Mobile after flashing a T-Mobile radio from Hercules (very closely related device to skyrocket... both are s2 variants)....
So please stop the useless advice of not recommended, or not advisor or such... It's xda not Facebook..
If 2 devices has the same chipset and/or the same hardware platform it could be very likely that the only difference between then is the radio software and the commercial name,. Unfortunately I couldn't find enough detailed (deep hardware details) info on the T-Mobile S4...
The main purpose here from this thread is that did anybody here try it and connected to T-Mobile LTE in USA successfully ?
Any update??

I would also like to know if the i9505 can connect to T-Mobile's LTE in refarmed areas. I'm holding out on the purchase right now but if it does work then I'll go ahead and buy 1.
As I understand it, I don't believe that the I9505 can connect to Tmo's LTE frequencies but it should probably get unto the refarmed (1900 mhz) 3g areas if you're in one of the big cities (ie; NYC, LA).
It looks from the specification that out of the box it will not work..It doesn't have the 1700mhz LTE band(which T-Mobile USA uses for the LTE uplink)..
For sure it'll need some"modding" or radio flash to work...
We need a guinea pig big-time here lol..Probably somebody buys it, flash the S4 M919 radio on it and report back...If it doesn't, ship it back to seller for a refund...
PS: it is useless if it won't connect to T-Mobile LTE(i.e. just 3G)..Pretty much everywhere will get LTE eventually...
We are still waiting for real Solution.............
so is it mainly coming down to the radio thats built into the chipset and not the software side of things, I wanted to flash the modem but I dont know if it will brick, blow up, or turn into optimus prime.... any ideas lads,
cheers

You have I9505 ? Are you on t mobile ? Do you have a good return policy for the device ? And in the return period ?
If so and you're brave enough, look for a flashable m919(T-Mobile S4) radio zip and flash it using any custom recovery ...Beware that this action might corrupt its imei or might cause a big problem that can't be corrected easily... So you're responsible for that ... But if successful you'll be able to use T-Mobile LTE and do the community a great service...,
Please let us know if you have any updates.

[Q] galaxy s4 gt-19500 compatibility with wind(Canada)

I bought Samsung Galaxy s4 Gt-19500 with Android version 4.2.2 out of Canada. The phone is sim unlocked. My original plan was to get a plan back in Canada and use it there. I found out that it was compatible with Rogers, Fido, and all the carriers who have a band 2600. Wind, Mobilicity, and the cheaper carriers is 1700/2100 and my phone does not work with there sim cards. I searched online and found this link:
http://forum.xda-developers.com/showthread.php?t=2291589 which is also with xda-developers but the download links on the bottom, downloaded 77zip which crashed the computer twice and also downloaded lots other programs with out permission. Is there any way to make it work with wind?
I don't need it to work with Rogers, Bell, Fido, or any other carrier after.
Much appreciated- Tyler
Hello i am sorry to tell you that the GT-i9500 does not have the chip needed to run on the wind net work (T-mobile in USA) the chip you would need is a qualcom chip the only international version that has that chi[ is the LTE variant of your phone GT-i9505 and no you cant swap chips nor can you flash a modem and get rid of that file that is crashing your PC if it does what it claims it does than its a lie and most likely a virus sorry for the bad news but my uncle had the same problem and thats why i have some experience with the phone i recommend you sell that one and buy the GT-i9505 or the T-Mobile SGH-M919 i personally have the T-Mobile version and no complaints just the bloatware but i flashed a rom and no more bloatware
Best Of Luck

N-9005 to use for AT&T?

Just a very quick question...
I moved to US recently and bought AT&T sim, problem is i cant get any data in my Note 3 N9005 LTE international. can I install the AT&T firmware 900T to be able to get the data?
Any particular firmware version?
Thanks in advance.
No, you will brick your device. The reason you can't get data is because the international LTE is not the same frequency with AT&T frequency. Try switching your data to WCDMA (4G in Europe)

Decided to pull the trigger and do this following a guide on Youtube. I used firmware G935VVRU2APD2 and followed this how-to https://youtu.be/WVzXvMa5FQ4 and everything worked out perfect.
