4G on D802 HKG version - G2 Q&A, Help & Troubleshooting

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?

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)?

I can't find Canada Bell S8500M firmware anywhere! Need help ASAP!

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.

Please help asap

HI, really sorry if this is a noob question but would someone be able to answer this asap. I live in the UK and purchased an S5 off ebay it stated it was the SM-G900F (UK varient I believe) but upon delivery I checked and its the SM-G900S which is the Korean vairent.
So I put my sim in and it displays that im roaming which is obviously wrong. Can I just flash a UK rom and will everything work like uk varient or is the radio bands or anything else different. Please answer asap as I will need to contact ebay.
Also is this 4G version and will it work in UK?

No, LTE bands are defined in the radio chip. You cannot change these bands by flash a different rom or modem.

Yes, as the cpu/gpu, screen and reoslution are similar i guess you could do that. Don`t know the supported LTE bands of the 900S though. Maybe its best to file a complaint to Ebay about the seller misleading you as you probably will not have warranty either.

Help me decide what to do now. [NOOB][VS980]

Hello everyone! I recently got a second-hand verizon G2 VS980. I live in India (location is relevant in my case because of this being a US only model). I had ROOT pre-installed and it stays even after factory reset. This indicates that it is NOT stock.
This phone has legit hardware, as in it has all VS980 components. I have checked it. BUT IT HAS THE IMEI OF A D800. Does this mean that i also have the bands of D800 enabled?
Now what i want to do is,
Above all i want this phone rooted and flashed to the latest and most stable ROM atm.
Second, i would like to use 4G LTE on it, here in India. I know that VS980 supports only band 4 and 13. I NEED band 3,5,40. I have trawled the internet for this specific info but to no avail. Does the VS980 has the hardware it takes to use other 4G bands? Or is it manufactured only with band 4 and 13 in mind? The only pieces of little info i came upon was this
jacob019 said:
After spending a few days hacking around with the VS980 (LG G2 Verizon Model) I wish to share some findings.
1. NV edits to the bands will only work with baseband 11A or earlier. All later radios have the NV values hardcoded into the baseband and any changes will be reverted. You can successfully edit the NV values, and they will survive reboot on baseband 11A, but as soon as you install a later baseband they will revert to stock. CM11 works well with 11A. Perhaps binary modification to later basebands would be possible.
2. LTE Band 17 does not appear to be supported by the hardware. I copied all the values from a D801. Android now reports my phone as a GSM model instead of CDMA which is nice, but it just won't connect to LTE Band 17. If I delete band 4, I can't get LTE at all, so I know the settings are having an effect.

and this. So i am confused where to start, i currently have a 26A baseband. Is it possible to enable band 3,5 and 40 on VS980?
I found the guides much confusing and complex relative to other devices i had. I am confused what to do first.
Should i flash TWRP first? or
Should i flash stock firmware?
I see that bands can be edited only on baseband 11A or earlier, so should i downgrade to that etc.
I have the phantom touches, and i read that they were gone after a specific update, so can i still get/flash that update with
a 11A baseband?
I do not understand this baseband, bootloader, exploits, and ROM compatiblity things.
I am willing to try even low level edits if someone is able to help and guide me.
Lastly, i just want my VS980 to run a good stable ROM with (if possible) 4G LTE on band 3,5 and/or 20 (India) and NO phantom touches update.

Bump. Noone?
Can't anyone tell me that does the verizon model even includes hardware capability for 4G band 3,5 and 20? If this gets cleared, more than HALF of my problems will be gone.

Yotaphone 2 Frequency and Radio Firmware - AT&T

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,

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.

Korean G600L LTE bands

Hi, I have a korean LG G6 G600L model. I am based in Germany and use the T-Mobile (DTAG) network. LTE Band 3 works but I would like to check the LTE band list on the device itself. Does somebody know the network test menu code for this specific device/network?
Additionally is it theoretically possible to exchange the modem driver to enable additional LTE bands (Band 20 in my case) ? Is it only possible with root?
Happy to test stuff on this device as I would really like to keep it and improve the LTE reception. I love the DAC btw.
Thanks.

Hello
Just a question
Do you think if i flash a different firmware (H870) in my mobile (G600L) i can receipt UMTS 900 ?
It will not help u to add WCDMA b8 900 to supported bands, because:
1. Korean submodels probably have no hardware antenna support for this band, which is totally unusable in Korea;
2. U will not be able to flash another submodel's stock to Korean models without root and some rom cooking preparations, flasher just restricts u to flash another submodel's stock;
3. In case u modify another submodel's stock enough to sucesfully flash it to Korean model, but without Korean kernel, modem and specific patches - it will probably softbrick ur device.

So I can confirm that G600L is not only showing the bands but also work with them. Band20 and 3 successfully tested here in Germany. Now if it would be possible to configure VoLTE with T-Mobile or cross-flash the german firmware but still keep the DAC would be perfect for me...
Looks like the Korean version has the most international 4G LTE Bands. The rest of the models in Asia barely have any 4G LTE Bands. Not sure what is used with this. Is the Korean version a dual sim version as well? Anyone have a picture of the box of the Korean version? There is usually a sticker on there that shows which 4G LTE bands are supported on box
---------- Post added at 02:58 PM ---------- Previous post was at 02:54 PM ----------
One more question.. Anyone here that has the Korean version able to tell us if it comes pre-installed with facebook? Do not want a smartphone with Facebook preinstalled that can only be disabled and not uninstalled.
