Best modem for n900w8 on att - Galaxy Note 3 Q&A, Help & Troubleshooting

I have a n900w8 (canadian note 3)unlocked and running on ATT US, but im having a very weak signal compared to my old att s4.
I wonder if anyone has been experimenting the same problem and recommend me another modem to flash and solve the problem
As far as i know I cant flash any att modem to a n900w8, but I dont know if a tmobile n900t modem work since custom roms are compatible with w8 phones
note: The phone is rooted and running a custom note 4 lollipop rom intended for n900t
any help will be apreciated:good:

Note 3 N900 Version on Tmobile?

I have the Note 3 N900 (Octacore version) on Tmobile and I was trying to figure out If I can use the Roms for Tmobile version of the phone on the N900 or not? Or is there a rom for Tmobile that can work for the N900?
N900 is kind of the least bought Note 3 variation, and so there is little development for it. Other than not having wifi calling and carrier bloat, what benefit would there be to trying a T-Mo ROM? Because of the differences in hardware, I would say that it's not recommended to flash a T-Mo ROM. Also, the point of getting a N900 or N9005 is that you don't want to be tied to any carrier isn't it?

[Q] SM-9006v - Using on t-mobile

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

mexican n900w8

Hello all,
Although a very experienced flasher and one point of time used to mod roms for symbian I seemed to be kinda confused of the note 3 i just bought.
I have this variant of note 3 n900w8 probably telcel /tigo and i got via ebay. I bought it cause I heard n900w8 is the best modder friendly device out of the available.options and also I plan to use the same in Canada.
As you can see in the attachement its on android 4.3 and I am planning to update kit kat and root it. Since its a mexican variant and I am.moving to Canada should I flash the canadian rogers/bell stock rom or the telcel one? Also should i root before flashing or not?
Incase Canadian firmware would be okay to flash, will the device work with Indian 2g/3g where I am currently at.
Thank you
Bump !! Any one please ??

Read first the threads in General about the W8, specifically those that talk about the "invulnerable" or "friendly" bootloader.

[Q] Do Galaxy S4 AT&T Firmware work on Canadian (Rogers) phones?

To be specific, the AT&T (jflteatt) has the CM12 with Lollipop on nightlies, however not the Canadian versions. As far as I know, both phones are identical except for carrier.
Has anyone tried to install the CM12 for jflteatt on a Rogers S4? what results did you get?
Also, I am seeing alot of safestrap and other new things I am completely noobish on, if I were to flash Lollipop roms, what is different compared to flashing kitkat roms?

Is it possible to flash a stock N910T ROM to N910W8? No difference in hardware.

Currently have a stock N910W8 (Unlocked, Telstra branding), thinking it would be a direct unlocked replacement for my N910T (T-Mobile USA SIM). However the N910W8 can't get 4GLTE no matter how many adjustments I make to the APN
The model number printed in the battery slot is the same, N910T. I thought this would be an easy switch.
I tried flashing the stock N910T firmware via ODIN but was unsuccesful. Kept getting a secure check fail about error using stock N910T DOK2 BL/CP and N910T EPK firmware. Do I not have the right versions?
Is there any other way to do this through ODIN without installing a recovery and rooting? Is it even possible?

Without root its impossible.
You need a modified custom rom from n910t that is compatible with n910w8.
in order to do that you need root and twrp recovery installed.
I beleive LTE bands are different in both models even if you flash n910t rom not sure you will get LTE.
And for wifi calling you will require N910T modem and with N910W8 its not compatible.

WiFi calling I can deal without, LTE I cant.
Just throwing it out there, why can't one flash N910T firmware on an N910TW8? The hardware between an N910W8 model is literally no different, the model number on the sticker of the N910W8 is N910T. It's not like I'm expecting N910T firmware to run on a Verizon or Sprint model.
There has to be some method to essentially brick a N910W8, removing all trace of N910W8 firmware, CP/CSC/BL data, then install N910T firmware and have it wake up in N910T hardware. Anyone?

Were you able to flash the Stock T-Mobile ROM to the W8 or did you have to root? I'm in the US and even after playing with all the settings the max Down/Up speeds I saw were 2Mbps/0.1Mbps on the Telstra N910W8, compared to my previous 50Mbps/50Mbps on the Tmo N910T.
No you will have to root....easy just flast team win with odin....then download su.zip and flash with your new recovery......why wouldnt you want to root?.......hell i still have my n910w8 motherboard rooted with custem rom if you interested in an extra. ..hope i dont get in trouble for saying that
I prefer to keep it unrooted for the OTA updates. Don't get that with root, updating would just be one more thing to keep up with.
Yes but me personally, like to update when i want to not when they decided i have postponed the update long enough and the next thing you know ur phones updated and u didnt get to have a say in it...but thats just me....not to mention first thing after root is removing all the blot and stupid apps ill never use...back ups are a life saver...iv bricked a device 6 or 7 times in a 12 hour period. ...
1. What about flashing the N910T PIT file along with the PDA, CSC, BL, and CP files for the N910T? What will stop this from succeeding?
2. What about a JTAG service?
3. Is there a differencertain between what ODIN does and using an unbrick image from a N910t from the SD card after a hard brick?
Open to anything at this point, except of course, using a 910TW8 firmware on 910T hardware which is all this is.
