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.
I cant seem to find a working sbf for the US. When I flash the UK I get a black screen, when I flash personal Argentina I get everything but I have no service. Can someone help me please? My network is the same as att. the Argentina says that the network is not supported.
Well, you may be out of luck as of now. If your baseband is not same as Personal Argentina (or similar LatAm ROMs) for which there is no root, you can't use baseband switcher and may just have to wait until those ROMs get a root option.
So there is no way back to my original sbf?

No, at least not yet... You can't root nor apply other sbf, you're stuck with it until someone finds a way to change it.
Is it not possible to root through sbf files? I cant believe I spent all this money and now I have a paper weight.

It's not possible... You can look at the discussion about Vivo BR and Personal AR In This Thread, although there's no solution yet.
OK, so will having another country's sbf make you now be able to use the phone? I get "Mobile Network not available".

What's your carrier?
Brazil uses 850/900/1800 bands for GSM and 850/2100 bands for 3G.
Argentina uses the 850/1900, the same band AT&T uses.
I've been in the US and used my milestone 2 in AT&T network without any problem. It won't work in T Mobile, since it uses 1700/2100.
Try with an AT&T (or one MVNO which uses their network, like H2O Wireless) sim card to see if works.
Maybe you could try using Vivo BR sbf. Our phones in Brazil are all carrier unlocked nowadays.

I'm using Straight Talk which is on the ATT network. I have not been able to get the phone working no matter what I try. I have checked the settings over and over.
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.

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?

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)?

Hey guys -
So like many of you, I reflashed my two Yotas to the latest RU Lollipop and was wondering if there was another radio firmware file that might wake up the AT&T US LTE bands. Any thoughts? Has anyone tried flashing the different radios to see if you can get a 4G LTE signal stateside?
Thanks,
Rootdude

HSPA+ can be sometimes very good - 3-15Mb/s - what is your speed at the moment? can you check through speedtest.net ?
At&t firmware
I have around 3.5 mbs to download and 0.6 uploaf. Too small comparing local 4G. So, can you help us?
I do not think you can change that easily, there's a thread talking about changing Radio Bands but the conclusion I got from the reading is that it does not work, at least with current "user" knowledge, YD206 is from China or HongKong, and some of those LTE Bands can work in Europe, not so much on the USA, the bands that USA telephone companies are very different than Europe or Asia, and as such YD206 IS NOT compatible with USA LTE bands. UMTS can have much higher upload speed than the ones you posted, so it might be your network problem, don't know if they are any better in LTE over your region.
Should be possible
Qualcomm 8974 supports all LTE bands. We just need proper modem firmware for US bands. Method in those threads definitely doesn't work since Qualcomm introduced some hidden filters inside firmware
BTW, there is lte_prefferedband file in the modem folder of Yota EFS. Does anyone know how to edit it?
That might be a anti-tampered code against our NV changes
Ok, I found out. For AT&T we need qcn file from Yotaphone 2, model 205. I don't know it such thing exist on the market but this reference says that it might be compatible with At&T.

interesting thing is that YD205 model was never launched, so it doesn't exist at all, unfortunately. The inquiries about future developments of this model were negative...
Hi there. I bought an 'unlocked' AT&T H910 LGV20 from ebay.
I thought would work in the UK as the phone hardware has compatible 4g bands that my provider (EE) uses.
The stock at&t firmware only allowed me to use 2g/Edge.
So I have flashed several other roms / kdz files using LGUP
( h910 Puerto Rico, H915 Canada, US996 unlocked US - variety of android 7 and android 8)
Some roms (particularly Android 7.0 Canada and Puerto Rico) work with 2g and 3g but there isn't even a 4G option in the base menus.
Some roms have global or allow you to select LTE/3Gpp but they don't allow me to get a 4g signal.
One even said 4g at the top but when I checked the connection in phone settings - about - it showed 3g (and this was consistent with the download speed too)
II only got videotron Canada to work. Bell and Rogers should have an overlapping 4g band but I got the CUST error on those roms.
I have tried going through service menu but all that can do is sometimes force a 3g signal from 2g
So what should I do?
1. I s there a rom with overlapping 4g bands that would work? Can I flash a HK rom onto H910?
2. Can I root the phone to unlock 4g bands?
Would this survive unrooting to allow me to access microsoft intune (for work email), banking and sports apps (which sometimes don't like root?)?
3. Would a custom rom work? Which do you recommend to keep as many features as possible eg remote control, camera, DAC?
Do they also work with microsoft intune, banking apps, sports apps etc?
I have followed a few of the posts out there but given the ebay seller I wonder if a few more people in Europe might have been tempted!
Thanks!
Hi
You need Band 20 (800) to use with EE UK and according to GSM Arena list of specs for the H910 that version of the V20 does not have it and I do not know if it can be added.

Thank you!
I was led to believe the H910 (same as H915 in Canada) supported all of EE's 4g bands.
But for sure, the carriers seem to have locked some out. But not having any luck with other roms either...
I cannot post the url but
frequencycheck . com
carrier-compatibility/wwW4hXP/lg-h910-v20-lte-a-h915/ee-everything-everywhere-united-kingdom
Compatibility - 3 out of 3 bands supported
100%
Interface Name Supported by device?
LTE B3 (1800 +) Yes
LTE B7 (2600) Yes
LTE B20 (800 DD) Yes
As I said in previous post the H910 does not support Band 20 (800) check GSM Arena site select LG V20 and then H910 and select LTE bands and you will see that Band 20 is missing. The H915 is not listed.

I have a similar issue, having bought an "unlocked" H910 and having only 2G. Is this the file name of the H915 kdz file you flashed to enable 3G: "H91510e_00_VTR_CA_OP_1205.kdz"?
Thanks.
