Hi, any anyone advise me how to confirm whether my phone is still 4G?

I have downloaded LTE Discovery app and it says my phone is HSPA on the Wellington waterfront. When I had Jelly Bean before it was showing LTE on top of the phone. Now it just says H with the two up down arrows.

I am with 2Degrees $19 combo pack.

Cheers.

Do you see 4G / LTE when doing a manual network selection?

Thanks I will do this tomorrow when back to work. I am in Churton Park now which I think Vodafone should have 4G coverage it only says:

2 Degrees
RAT: WCDMA
RAT GSM

Vodafone NZ
RAT WCDMA
RAT GSM

Is 4G turned off on the handset?

I am running Kit Kat now - is there a way to turn 4G off?

I had it with Jelly Bean unless I am needing to back date the OS.

Under settings it just says Use only 2G networks - is NOT ticked.
Under Network Operators it just have search networks or select automatically.

Sounds like you installed a Kitkat ROM without LTE support. Was it an official update for your device or did you flash manually?

Yes notification on handset. Late last yr might have been this year. LG via eBay Korea.

I know some manufacturers only enable LTE on networks they know support it. This is by means of a list on the handset, so usually regional or country specific. Its possible LG went this way with the Kitkat upgrade for this phone, so if it is from a different region then it won't know the NZ networks support LTE - just a guess. In which case you might be able to enable LTE by flashing a ROM from another region closer to home (or some unlimited international version).

Under manual network selection. If there is LTE support, what should it say?

A bit of google search found that this handset might have been only available mostly at Korea. This phone was not available at all in NZ via the proper channels. The G2 was released here but not the original G. It was said that software outside of Korea might have the bug or the intention that 4G was not enabled. Some said switching to the Korean software.

I did that now my phone shows no signal. I have downloaded the "base band". How do I apply it?

Grab the international ROM and Baseband then apply those. There will be guides on XDA of how to flash these.

For the life of me I cannot find a guide to load this baseband. I have downloaded a 20A international baseband and I have loaded a international version of 20A Kit Kat ROM. Just no signal now. WiFi works.

Anyone know how I load the baseband in layman terms?

If its anything like the Nexus range (haven't checked), you go into the bootloader (assuming unlocked), connect to a PC and use the 'fastboot' tool from the android SDK.
Then you type
fastboot flash radio RADIO.IMG
and then reboot.

Alternatively, you can often flash them from a zip file once you have a custom recovery installed (TWRP recovery).

Will look into today after work.

I held volume down and power key ut booted into factory restore startup. Is there no recovery mode on this yet?
