[HELP] [Q] No Mobile Data Signal

Hi,
I recently was getting frustrated with the ROM Gummy. ROM GUMMY: (http://forum.xda-developers.com/showthread.php?t=2563973) so i wanted to try something new and never thought i'd get a problem as when i flashed GUMMY it was so simple and everything worked.
However, when i flashed to the ROM S4 Google Edition: (http://forum.xda-developers.com/showthread.php?t=2544474) i noticed my signal / network won't stay connected. It may work for 2mins then disconnect - so i tried another ROM thinking it was caused by the S4 Google Edition.
I'm now currently on KOT49H【4.4.2】Google Play Edition (http://forum.xda-developers.com/showthread.php?t=2557353) and still getting no signal, only if i keep changing it to automatically find a network.
I've been reading it could do with Modems, or have i really messed something up and won't be able to fix my phone? I'm sort of new to this all so if you could explain more than tell me to do something that would be great.
Phone: Samsung S4 i9505
Baseband Version: i9505DVUBMGG1
Network Provider: GiffGaff (o2 Company)
Any help would be great.

You have to flash a new modem for 4.4 like nb9. If you have a bootloader without knox, flash only the modem.bin file. If you have knox, flash modem and non-HLOS.bin. there's a nice modem thread in the general section.:good:http://forum.xda-developers.com/showthread.php?t=2192025

[Q] Can I flash G900F modem on G900W8 and how?

I've been having a problem on my S5 where the data symbol is stuck on 4G and doesn't show anything else. It might be a baseband/modem error since I'm using a Canadian model in Cyprus. Can I use the modem from the Cyprus G900F firmware and flash it on my G900W8? Also can someone explain how I could do that so that I don't screw it up, if it is possible?

!
RE UP!
Same pb...

To flash a modem you need a .bin file and odin.
Clear your delvik/cache,
put your phone in download mode,
load phone with the .bin file and flash it.
I also am having data issues with all custom ROM's. If it's not one thing it's another. Canadian phones always get left in the dust it seems.

Probably not. You neglected to tell us what your W8 baseband and firmware are, which is rather crucial information. Making it impossible to give you a definitive answer. In most cases Odin will refuse to allow the change.
That isn't really an issue most of the time. There should be a variety of W8 modems for you to choose from if you want to change your modem.

[Q] Carrier Specific ROMs

Hey Guys!
I have a question regarding stock roms. I've been looking at SamMobile for an official release of Lollipop here in Philippines, the only download I can see is for a local carrier Globe. Will it cause problems if I flash this on my international N9005?
I also want to ask the same question for an S4 I9505, but it's the other way around; the phone is from Globe, network locked, and I am thinking of flashing an international version ROM. Will this cause problems? I know this isn't the right forum but just in case someone would like to answer.
Thank you!

1. Yes, you will have problems with the radios. It's not importat where you live that what CSC have your device. Install this APP and look for your CSC. Go to Sammobile.com, look for your csc, download and flash the latest stock rom for your device via ODIN. (Pic attached)
2. Regarding GT-i9505: Yes, it will cause lose of signal. The best you can do is unlock it by IMEI.

I flashed a rom from Brazil. Everything works great it's just that the bloatware included is annoying. I figured the best option to flasha ROM from my country but the only one with a Lollipop ROM is carrier specific.

Samsung allows users to use roms from their own region interchangeably. In most cases, even globally.
I've never encountered issues with radio or signal loss when flashing different providers and countries in my own region, and I've had thousands of people flash and use all sort of different EU firmwares. (you can find the region on the sticker on the box.)
(US users have different devices with real carrier locks, so those are excluded.)

Samsung note 4 not getting anything more than 2G

Hey all im totally new to this and i apologise if this has been covered. I had a samsung galaxy note 4 and my darling kids thought it would be an epic idea to stick things inside the charge port totally ruining it and making the phone unchargable. So i contacted samsung repair center and was quoted a ridiculous price to repair and i just bout a new one to only find that its not an australian version i have a sm-n910k and my original one is a sm-n910G what can i do i cant get 3g i cant get lte i can only get 2G and minimal bars of service at that if anyone can help any advice atm is great advice thank you all in advance.

Go to settings/mobile networks and set apn settings manually depends on your sim carrier and country.
Just google your sim carrier apn settings and you will find easily.

I have already done apn settings and still to no avail i cant work this out for the life of me the only thing i keep thinking is that this model may not be compatible with my country as i know the sm-n910g is australia and the sm-n910k is korea i think ive bought myself a dud unless theres something i can do software wise idk any input is great imput though :/

Did you bought a new device, n910k or was it a replacement part? If you're comfortable, you can always change the USB port itself. I've done it for my Note 2 before. The USB port should be just a ribbon cable so you don't have to worry about soldering and stuffs like that. The prices are also way cheaper too.

Apparently the usb port is tricky to replace as its apart of the screen as samsung has told me and its a whole new device its the korean version im not sure what to do as the place i bought it from is a long distance away from where i live and i was wondering if there was a way i could install like the sm-n910G firmware to it. Im at my wits end with this and not sure what to do.

Oh right. I forgot about that. It was a simple plug out and in for my Note 2.
The issue right now is that the n910k, most probably does not support Australia's LTE bands. Hence the reason why you can only connect to 2G. You can check out gsmarena for the supported LTE bands for different models.
You can install a stock Note 4 Exynos firmware from another country with a carrier that uses the same LTE band as your carrier. It should be safe as some members here are able to install different firmwares meant for another device on their device, example N910G on N910F provided the CPU are the same.
Go to SamMobile, and find the firmware for Note 4 and you can see a list of Note 4 firmware available for download. You need to do some leg work though to ensure that the firmware you're flashing is meant for the Exynos version and the modem supports your carrier's LTE band.
This video shows what I'm talking about.

Ive found the firmware for a sm-n910g can i use that to go over the sm-n910k? It has the firmware aswell as a csc which i think im going to need to research to know exactly what im doing as i have no clue atm lol but cheers heaps man i feel like im getting closer

No don't install over the n910g over your n910k. N910k is using a different cpu than N910g. N910k uses Samsung's Exynos processor and N910g being a Snapdragon processor. Idk what would happen if you flash a N910G over a n910K but I think it would be considered lucky if your phone would be able to boot up.
Your n910k should be able to run on another firmware meant for an Exynos processor like n910c. I just don't know if, after installing over your 4G would work because of different LTE bands. But this website says there's a chance it might work.
https://www.frequencycheck.com/compatibility/zYzu9/samsung-galaxy-note-4-sm-n910c/australia
Usually in most cases, when a user accidentally installs a firmware meant for another variant, assuming they would get past the samsung boot up scene, they would not be able to get any network connections. This is due to different firmwares having different modem files for the different LTE bands. However if you were to install over a firmware with the same internals as your current device and more or less uses around the same LTE bands, it should work.

Here you go. It's every firmware ever listed. You need to create an account before downloading though and the download takes forever. You can install the firmware when your phone is in download mode using Odin via your computer.

You can try a random one. Preferably one without a telco. Example, N910C and not N910C (telco name). It shouldn't matter much as the difference would be that the one with a telco would come preinstall with the telco apps. Also, preferably from a English speaking country because usually the language would be based on country.
I would recommend you to download the original firmware for the n910k in case if this fails, you would be able to fall back to the original firmware.

G900F Rom Recommendation

Hi,
I have a G900F I got in the UK and I've just moved to Canada with. Problem is it doesn't support some of the bands here so I find I often have a poor signal. I'm happy with the stock ROM but I believe if I am to open it up for all bands I need a custom ROM.
I don't need anything too flashy, but I'd like everything to work and be responsive.
In terms of the most complete ROMs it seems LineageOS Official and Resurrection Remixed are the most popular. Can anyone comment? How about Android 6 vs 7?
Thanks

Used to use resurrection but now that I've moved to lineage os I can say that its better and getting improved every update it gets

g900f is almost identical if not the exact same as the canadian s5 g900w8.
you would need to use correct freq for your carrier, search will provide a howto. worse case scenario is to flash a canadian 6.0.1 modem from any canadian 6.0.1 stock fw

if trying to figure out connectivity, stay w/stock first as modems are from stock fw.
imo try superlite 6.0.1, it stock based and only takes a few minutes to install that way you can test out your carrier connectivity issues
https://forum.xda-developers.com/ga...-superlite-mini-mm-v1-0-361mb-g900w8-t3497158

So I can keep my stock firmware and just replace the G900F baseband (G900FXXS1CQAV) with the Bell Canada SM-G900W8 Modem and everything will be the same except the phone will work on the Bell Canada frequencies?
I had been planning to follow this guide: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 to enable the 1700MHz band which is disabled on the G900F, but if flashing a Canadian modem will enable this band that sounds easiest.
Do I need to download the full 1.5GB firmware and extract the modem from it?
Thanks

ive never tried flashing a mdm from another model as ive never needed to for the s5.
ive not read enough to know if its possible or if it has any neg consequences.
easiest would be to change freq w/current mdm, search for samsung secret service codes to view and maybe change current freq
good place to start is here https://forum.xda-developers.com/showthread.php?t=2729694

I've done a lot of research on this forum. Most people say that installing G900W8 firmware on G900F isn't possible. Also it seems that it is the NVRAM which stores what bands are allowed on what model, so simply flashing a different modem won't make a difference.
Some people are saying that the hardware is different and this is what limits the bands, but I don't believe so, the radio/modem chip is the same version between models.
Trying to follow the link I posted earlier to change the NVRAM values after installing a custom ROM appears to be the only way. Some people say it works, and others say it only appears to work. The original thread was closed years ago so I guess I'll just need to try it and see.
Alternatively I could buy 2 phones, one W8 to use in Canada and a F to use in Europe, this seems silly though.
