[Q] Flashing roms

Hi,
I have SGH-M919V and its unlocked.
I am on Bell and want to use LTE. But this model has LTE disabled. when i enable it, cant make phone calls.
I cant seem to flash T mobile modem via odin. there is this secure boot issue. the AUTH: Fails.
I was thinking of installing Bell SGH-I337M rom on my phone. Is that possible? If so, how do I go about doing it?
Thanks!

Since you have a T-Mobile variant you should ask in the sgs4 tmobile forum...
However your problem with lte/phonecalls is likely just an APN issue
To further assist we would need to know which carrier you are using the device on

Hey. thank you for the reply, I really appreciate it.
I've been asking a lot there. No one is answering.
Please help me out, please.
My phone is Canadian variant, originally from WindMobile - SGH-m919V. Wind uses Tmobile freq. = 1700/2100 (AWS) only. No LTE.
I got it unlocked two days ago, and switched over to Bell carrier. Bell uses the other freq and LTE.
When I do force LTE by *#2263# - and enable all LTE, i get LTE speeds. But NO calling or texting. this is with the original Windmobile stock rom. No modification. No root.
I tried to flash Tmobile modem via odin 3.07, didnt work. I used the phone button to load the modem.bin. It gave me AUTH: Fail, secure check fail.

I agree, wrong forum, but we are here to please....
if you have a M919V then you would flash the rom you want, before you boot, flash a tmo m919V kernel, it will boot, manually add your apn settings for your device, it will work with data/wifi/calls.
Good luck....

Hi, im sorry for posting in this forum.
so if I want to flash the bell rom - I337M stock original rom , how do I flash it without booting??
And then how would I flash the tmobile kernel so then I can boot??
I dont mind keeping my current rom - wind stock. But, I want to be able to use LTE like how tmobile has pentaband 3g plus lte.

4G on D802 HKG version

I have a D802 Hong Kong version. In the secret menu (3845#*802#) i have found this: LGD802AT-00-V10C-HKG-XX-NOV-30-2013
Now, I would like to use the 4g connection in my country (Italy, carrier TIM) but the 4g option is not avaible in "network mode". After a test with another G2 (italian version and same carrier), I can say that the connection don't switch automatically on 4g but keeps the H+ one. So i think is necessary a modification.
Solutions?
Is it necessary to flash an europe radio? or something else? I'd like to keep the stock rom Lg but is not a fundamental.
Baseband: M8974A - AAAANAZM - 1.0.190036
Kernel: 3.4.0
Build: JDQ39B
I have the g2 for two days. I know it very little. I do not have much knowledge about it. Some good soul can explain to me how to do?
I need your help!

Did you verify that the device has the correct radio bands for the lte on that carrier?

I don't know how to check! On the box of g2: gsm 850/900/1800/1900; wcdma 850/900/1900/2100; LTE 2100(B1)/1800(B3)/2600(B7)/900(B8)/800(B20).
My carrier is Tim but i don't kwow which band uses.
In secret menu/LTE Band section: avaible band 1,2,3,4,5,7,8,17,20,40. No one is selected.

Can i flash V10E firmware for Italy on V10C firmware for honk kong (actually on my device)?

Flashing different firmware wont help. Its either your apn is wrong or you didnt enable lte correctly. I checked and TIM uses 1800 (band 3) lte which your phone should work with.

maybe i should enable "band 3" in LTE setting in secret menu.

Hi,
I've a similar question and I hope someone could help me: I've a G2 phone using the D80210e-ESA-XX firmware.
In the product specifications, supported LTE frequency bands are 900/1800/2100/2600/850. I know that in Italy working frequency bands are 800/1800/2600. Now, my phone does not support 800 MHz: do you think is possible to upload a different firmware (IT or EUR ones) on my phone? With one of these firmware, does the device will work at 800 MHz?
Thank you so much.

I also had the D802 with Korean firmware!
Even though the phone itself supports LTE the Korean firmware doesn't!
I flashed the EU version and everything worked fine afterwards!!!

Hi @zacharias99, are you using the LTE in Italy?
@sunshonic, I didn't understand if your LTE works in Italy using the secret menu. Is it working?
Thank you

No no i am using the LTE in Greece!!!
But LTE is LOCKED in Korean firmware!!!
In older Korean Firmware you could activate LTE from secret menu but in newer version this option has been removed!
The only solution in my case was to flash a european (or in your case italian) Firmware and everything worked like it should

@popsi, @zacharias99 did you follow a specific procedure to upload the european firmware. I'm not so sure to perform it cause some month ago I've bricked an old Motorola (I don't remember the exact model) using simply a firmware of a different country. The result was a brick cause two firmware did not use the same way to allocate the memory...

My friend i don't really know where in this forum the instructions for flashing a new stock firmware are... (I am also new in this community)
And i flashed it with Greek instructions so my link won't help you and i don't want to post some link i haven't tested by myself...
Sorry i hope you can understand!
At moment i have no time, but if I would be you I would search in the G2 Section for instructions!
They must definitely be somewhere!

Did you subscribe for LTE with your carrier?

@zacharias99, I've checked that 4G can be enabled using the secret menu
1. Go to LTE-Only
2. Modem Settings
3. RAT Selection
4. Select GSM / WCDMA / LTE auto
as in the post http://forum.xda-developers.com/showthread.php?t=2494751
At the moment it doesn't seem to work for me, probably because my sim still has not been enabled for 4g.
Have you ever enabled this option (with the previous korean firmware, I mean)?
@zacharias99, @popsi: the new european firmware allows to navigate over the 800MHz frequency band for you?
Thank you

Hi,
the procedure using the secret menu definitively works on my D80210e-ESA-XX, but I need to re-select it after every reboot.
Does anybody know how to make it permanent or how to automate this selection on boot (maybe using Tasker or something similar)?

[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

[Q] Can I flash UK firmware on my canadian GS5?

I bought my GS5 from Canada which means it's set on canadian LTE bands, now I'm trying to use my phone in UK and it doesn't connect to data network, not even HSPA so I was thinking that flashing a UK firmware might solve the problem because I read somewhere that since GS5 runs on Qualcomm its hardware supports all LTE bands by default but I am still afraid that the wrong firmware might brick my device. Can anyone please confirm that information. thx a lot

As long as that firmware is supported by your specific GS5 model this should not be a problem.
I live in South Africa and have flashed many stock firmwares from different countries.
Just a note... you might not have to reflash the entire ROM but merely flash a supported modem/change the csc. Changin the csc does however factory reset your phone.

Yes but a different csc file from the stock rom version will prevent the phone from receiving ota update. Anyway it's not my phone so I won't take any risks and the owner seems to be fine with hspa connection.

Search sammobile.com for the phone model and stock firmware from UK. Just flash that and then you won't have to change the csc

Looking for UK Three Network 4G Super-Voice enabled firmware

I currently own the Galaxy S7 edge UK (unlocked) unbranded handset, however my network is with Three. Supposedly you need to have bought the handset from them to have 4G Super-Voice (VoLTE/HD-Voice) enabled, so I'm wondering if anyone can help me source the firmware. I'm sure this will be useful to anyone else on the Three network with an unbranded handset.

Do you know what csc code they use?
Might it be this one?
Please note that this is just pure guessing. But it was the only one I could find that had anything to do with "three"

I'm not sure the CSC code, but this looks promising. Couldn't find anything regarding Three myself. Thanks

Three is a brand of CK Hutchison Holdings (Hutchinson 3G -> H3G). More info about: HERE.

Just download the app from playstore

I'm trying to do the same thing. Have you managed to get it workking. I found the following three firmware: H3G-G925FXXU3QOLD-20160111115713.zip

Latest BTU firmware has it as default (3 sim on unbranded S7 Edge).
Use the Samfirm tool (http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647).
1. Set "Model" as SM-G935F and "Region" as BTU.
2. Check "decrypt automatically".
3. Extract the decrypted file with WinRar or similar, then use odin to flash.

No need to lock will stay default unless it auto changes by itself but for me its okay and 4G voice works fine as default like on all devices

There is no need to flash H3G firmware any more. I have returned back to stock unbranded volTE works.
Just use smartswitch to revert back to stock firmware!

Sorry for the bump but does anyone know what settings were changed on the S7 root directory to allow unbranded devices to connect? I looking at modifying the files myself for the 6P as Three don't seem to be taking the rollout seriously for unbranded devices - so far the only thing I've found that relates to H3G is the mcfg_sw.mbn that states "No VoLTE" within, though the Swedish H3G configuration allows VoLTE, so I'm going to try modifying that unless anyone around has any ideas?

I've got a three s7edge couldn't get volte to work ended up flashing btu firmware and there is it listed in Network and it's working when there is no coverage as I get a volte displayed along with the empty signal bars

My stock firmware on a UK model has VoLTE enabled for Three UK. It's just not prioritised and only kicks in when low 3G signal.

As far as I understand it it will only work when u have no or very little signal
It's worked for me a few times such as deep inside a building
