I am having signal issues with the n9100 (china mobile). Currently I am in Canada on Rogers network. I have rooted the phone and currently using a custom Rom (Aurora). The firmware is on 5.1.1 and baseband is on the latest. I do get 4G signal but it gets weak when I am inside my house and usually is in Edge mode. The signal was decent when I was in China. I am sure its a modem issue, but is it possible to install a rogers modem onto this without bricking (probably lose dual sim but thats ok)? If not, is there a fix? Can I force my phone to use a certain frequency/band that Rogers uses and see if that helps?

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
Hi well I have the i337m it was for Telcel Mexico the baseband is i337MUMUEMK6, but i'm using it on AT&T, I'm running Phoenix Rom V9.4 but on reboots it takes quite a while to register properly on the network, however once registered is rock solid with Cell Signal and LTE. So I want to know if I need to change the modem and if so, which one.
When I was using Google edition 4.4.2 by Danvdh the delay was less than the one i'm experiencing now.
Thanks.
Nevermind problem solved, the problem was the "special" magic sim elite dual sim adapter. This adapters are expensive as hell for the lifespan they have. They start to fail gradually until they broke...
Hi all,
I own a SM-A500M phone. The phone has unlocked stock rom (original rom is not modified by carrier) and updated trough OTA to android 5.0.2. I know 4g does work in my phone because I could use it with my prior carrier, but I recently changed to CLARO and with this new provider I don't have 4g acces, only H+ and it is really slow and laggy connection.
I know the following:
1) Sim card is a compatible 4g nano sim
2) The carrier CLARO has 4g coverage where I live
3) The phone is not the problem
4) I have tried all the usual FAQS (APN's, select LTE in config, reboot) with no success.
5) The phone's variant is right (latinoamerican brand), so It can't be due to frequencies or bands problems.
I asked for help in CLARO and told me that this has happened amongst users with unlocked phones (that is, rom not modified with CLARO's bloatware), and the solution is to flash CLARO's rom. But the problem with this solution is that CLARO hasn't released android 5.0.2 update (and I think it will never update) and I really like android 5 and wouldn't want to return to 4.4.
So, is it true? Is there a chance to fix this problem with minor tweaks? What is the problem here?
Since I recently acquired this phone, I would prefer not lossing warranty, so rooting and custom roms might not be an option.
Thanks in advance. Kind regards!
You could try to flash their rom and check if it works. Then you can be 100% sure that hardware/chip/network provider are fine. I have the same phone on since last week, but still did not go to get the chip at a movistar office. Maybe you need to activate the chip and they refuse to do it unless you get their rom. Maybe just getting their rom, and then flashing back the updated stock one or a CM or whatev would be enough.
Hi there, I would like to know if other people are having signal problems after the MM update. I am on Tmobile on a AT&T Unlocked Priv that WAS working perfect (signal strength wise) when it was on Lollipop. Since I upgraded by OTA to MM using a friends Simcard my signal is a mess. It cycle between LTE , 4G, 3G, EDGE all the way to GSM (G). And when I hit the road it stay in EDGE most of the time. That didn't happen in Lollipop and have never happened in my Nexus 6 and Nexus 6P. So is no TMO signal, is something that AT&T or Blackberry change on the modem firmware.
I tried to flash the old modem (lollipop) but it won't boot and told me the data was encrypted and corrupted and needed to wipe my phone. I flashed back the MM modem and booted. I flashed the TMo modem and I don't think it is sticked or maybe is it just the same one. Can you reply with your baseband numbers. Mine is MPSS.BO.2.6.2.c2-0007-M8994FAAAANAZM-1.55185.2
Any help will be very appreciated.
