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)?

I have an international G2 D802.. We, in india have certain operators in Band 40 LTE.. Is it possible to activate Band 40 in D802 by flashing D802T kdz in D802??? Kindly Help..

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?

Here are the specs http://pdadb.net/index.php?m=specs&id=5448&c=samsung_sm-g900s_galaxy_s5_lte-a_samsung_pacific and here http://www.droidgod.com/2014/05/samsung-galaxy-s5-sm-g900s-full-specifications-features/. It looks quite similar for the G900F but check if the supportd LTE bands are compatible.

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.

should I buy international or carrier specific?

I will travel to the US shortly and want to buy an S5 to bring it back with me on my way home (Mexico). I think both the AT&T 'A' and the international 'M' version should cover my frequency needs ('M' has an extra band), but I would like to get some insight on which one might be a better choice in terms of Rom development and official updates (pushed out sooner). Thanks in advance to everyone.

AT&T have a locked bootloader so you can only use AT&T branded firmwares on a 900A.......
If you find yourself in an area/country that uses a different radio/modem band to AT&T, this could be a problem........

Thank you so much. Mexico (on my carrier) uses the same bands as in AT&T but seems like the international 'M' version might be a better choice isn't it?

I would say probably so.......
I believe the AT&T's locked bootloader makes it harder to root as well, and because only carrier specific OS can be loaded, I'm sure that's had an effect on the custom rom development for the device too......
I personally would choose a device with as few restrictions as possible.....

Different model numbers

Are A2017(Chinese) , A2017U(US) and A2017G(Global) three different device model numbers (hardware wise)?
OR
Are they three different firmware numbers that can be flashed on same hardware device?

They are different devices for different regions

And with the locked bootloader they aren't able to be flashed to different region.
Each have different bands for phone too...

Thank you for the quick response.
So I presume the A2017G global firmware cannot be flashed on c Hines model A2017.
I am planning to buy the chinese model A2017 for use in Singapore. I Have verified that it does support the LTE network bands used by Singapore telcos. The seller on aliexpress confirmed that it will work in singapore and has English language and all Google apps
Would that be a wise thing to do or should I buy the global device model A2017G?
Would you happen to know out of A2017 and A2017G, which model has better
Dev support on xda? (From the perspective of rooting, unlocking, AOSP Roms etc)

Both.
Hardware-wise, the three models are banded differently, and support different cellular connections. For example, the US and China models have CDMA support, while the Global model is not banded for CDMA. The three models have differing LTE bands as well (US model tailored to LTE bands used in North America, Global model tailored to bands used in Europe/Asia, etc).
Software-wise, they're pretty similar, but there are some differences. For example, the Global model has lowered audio output (compared to US model) potentially due to EU regulations. On the flip-side, the Global model has a special menu option for "Glove Mode", to make the phone easier to use when you're wearing gloves, which is omitted from the US model. The US model has an included theme called "Stock Android", which is missing from the China and Global models. The China model does not come with Google Play services by default, because China.
Support-wise, ZTE USA has a community forum that employees participate in to answer questions and whatnot, as does ZTE China. ZTE Europe, however, does not seem to, and can only be contacted via phone/email.
Someone here on XDA was able to flash the Global model's ROM on a US model, but had to specifically flash the US model's modem in order to get cellular working. However, it might have been because the US model can be bootloader unlocked, so the US model can be flashed with other ROMs. The Global and China models don't have official bootloader unlock yet (I'm not entirely sure if the unofficial method posted here on XDA works on the Global and China models)

Thank you for the detailed response. Much appreciated.

Search for Axon 7 reviews on Youtube. Any review that shows a white Android app drawer icon in the middle of the nav bar is a US unit using the Stock Android theme.

Damn I'd love that stock interface. Now I'm running Pixel Launcher.

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.

Engineering menu:
Dialer: 5457#*600#
Lte bands in Korean G600S/K/L:

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.

I will change my modele by another

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.

how did you bring up that menu with all the bands? I have the lg h870ds model with hifi dac and 64 gig, but I can't locate the LTE bands to turn them on

Try the same but with 870 instead of 600.
