I'm lookong for a LG G4 H815 but I would like to activate LTE band 12 just for data, not for call over LTEVoip. If there is no signal for calling, I'll turn LTE off to force the phone to call on GSM. Of course I'm on T-Mobile.

So, was anyone able to add LTE band 12 and verify that it actually works on a LG G4 H815?

Has anyone succeeded to to enable lte band3 on Verizon VS986?
[G4 General] guilamu:
I can't find anything like that for the LG G3. Am I missing something or is there no way to unlock bands on the G3 ?
[G4 General] shoiebarshad:
[MENTION=5144561]guilamu[/MENTION] you can only enable the bands which are available on the other variants of your phone with same chipset. i.e. qualcomm 801 etc [MENTION=7027804]davidoes[/MENTION] i have enabled the bands for galaxy s5. if it doesn't work for you try flashing an AOSP rom with AOSP kernel. some anti-tampering code is found in some vendor firmwares.

Yeah of course, but how do I do that with the G3 (not the G4)?

Thanks a lot for you help.

DFS CDMA Tool crashes upon Write

Hi,

I have a G4 H818P on v10i, rooted. Phone gets recognised correctly.

I tried to follow your guide and each time I click on the Write-button the CDMA tool crashes. The last message in the diag window says "Write NV Item (BAND_PREF_16_31) Skipped".

When I start CDMA tool, I see two options under the "Add port" tab: COM3 - LGE Mobile USB modem" and COM6 - LGE Mobile USB Serial Port"

When I click on the USB modem line, the device name in the "Devices online" box stays empty ([]), whereas the USB Serial Port displays "[LGH818PA] ....".

No matter whether I enable onle COM6 or both, it crashes on write.

Btw. READ showns on my H818P LTE band 1, 3, 5, 7, 8, 17 and 20 as enabled.

I run it on my Win10 x64 notebook, I do not experience any other issues with it, e.g. rooting went flawlessly.

Any thoughts welcome!

Cheers, Stefan

[G4 General] ruijay:
Tried this method for the VRZ version VS986 and I got the error in the attachment when I tried to write (add more bands)

Is this exception cauze by bootloader being locked for the VS986?
[G4 General] petermg:
I just did this with the Verizon G4 to see if I could use my Cricket SIM in it, which works fine in my AT&T G4, but even though the software claims the bands are enabled, it doesn't connect to the same bands as the AT&T one does and I can't get 4G/LTE unless I force it in a hidden menu, and then calling doesn't work... so..?

[G4 General] Knowbody42:
So, I just tried unlocking a couple of bands on my H815 EUR

cdma tool is able to read the bands fine, but if I try to write, the program just dies, with a generic Windows error message saying it "stopped working".

In the log window I see it says "skipped" for the two "write" steps that were there.

[G4 General] WTF?:
The H815 comes with hardware (radios) and antenna for the following LTE bands - 1, 2, 3, 4, 5, 7, 8, 17, 20, 28

they are all enabled by default, and nothing you can do, regardless of whether your bootloader is unlocked, or you are rooted, etc, is going to get you any additional or different bands
[G4 General] Knowbody42:
The OP says he unlocked band 40 for LTE, as well as WCDMA 800 and AWS. So there are certain bands that will unlock.

The hardware is there for it, because they are available on other variants. And it's far cheaper for LG to lock them in software than to have separate hardware manufactured for each different variant.

I'm specifically interested in unlocking band 40 LTE, because Optus uses it.
[G4 General] WTF?:
what I was meaning is that certain models only have certain bands, and those variants that are country coded rather than carrier coded are nearly always completely band unlocked - so for example, I have an H815 - it comes built with hardware (radios) and antenna for the following LTE bands - 1, 2, 3, 4, 5, 7, 8, 17, 20, 28 - and on my country coded version for Czech republic, ALL of them are enabled by default. So this phone would actually work in many countries, though I only use a couple of the bands here in USA.

there is no way to turn on band 40 in this phone, because the hardware for that band is not inside the phone, so no magical software, even Qualcomm's in-house software, can turn on a band that is not built into the hardware.
[G4 General] Knowbody42:
The H815T has band 40, and OP said he did unlock band 40 successfully.
[G4 General] autoprime:
it's not always the case.. but many phones have hardware capable of more bands than advertised. With the EUR H815, band 40 is able to be turned on. while not enabled by default.. both the modem and the antennas are capable of supporting this band if the proper edits are made.

the EUR H815 hardware is also capable of band 12.. but due to "politics" it is disabled in the modem.. so even with software edits it's blocked.

Write was successful. When I re-read the LTE values after reboot with DFS, Band 20 is enabled, but I don't get a connection (Vodafone Germany).

If you want to try it yourself: On Marshmallow you have to use *#546368#*818# for the hidden menu (Thanks to some Russian forum: http://forum.androidbg.com/showthread.php?tid=79632 )

then your phone respond (most llkely with the prompt $).

Then,

su

echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable

[LG G Watch R] Obiwanhug:
Last week i had the same problem (again), but this time after upgrading my Honor 3C! I try all the solutions I could find on the net, but none have solved... so after 2 days of trying everything (I even factory reset my phone and watch) I solved the problem... so you could try this!

1 - reset your watch;

2 - pair with other device (not your phone) like a tablet (I pair mine with my tablet);

3 - wait until the watch get set;

4 - go to the configuration menu on the watch and select bluetooth connection;

5 - put your phone bluetooth on and in visibility mode;

6 - wait until the watch find the phone and pair with him;

7 -with the phone and watch get paired, reset the phone;

8 - pair with the phone via android app!

I know that is a little confusing and with a lot of step, but in my case solved the problem since this way the phone received the correct pin from the watch, allowing for connecting with android wear app!
[8125, K-JAM, P4300, MDA Vario ROM Development] scotch whisky:
I am a bit surprised that so many new WM6 ROMs are appearing on this board. The majority just appear to have been created using the Pandora kitchen.

The Pandora kitchen is so incredibly easy to use so why not just create your own ROM. We all have different requirements so no downloaded ROM is likely to suit anyone other than its originator.

The current Pandora kitchen is IMHO close to perfect. Cook your own it really is easy.

Provided you only flash the OS and nothing else you are no more likely to "brick" your Wizard than if you flash one of the preprepared ROMs - perhaps even less likely.
[8125, K-JAM, P4300, MDA Vario ROM Development] WizeMan:
Dude, not all ppl have the patience, the knowledge (to edit files, edit/delete hex strings), and probably neither the courage to flash their own device for uncountable times in order to make something that will suit their needs.

I am not trying to tell you that I've got balls and super-knowledge to do that and someone else doesn't. The Pandora's Box is awesome, so is the Core Pro Kitchen also. But If it was THAT easy, MS would have also released a kitchen for every user to cook their ROM.
[8125, K-JAM, P4300, MDA Vario ROM Development] Whiterat:
Im afraid I must agree with scotch whisky.

It reminds me of all these "WINXP UTILITIES AIO 2007 XP GOLD" packages that you often see.

I moderate a few boards and I do remove such things, Its not to say that what is being produced here isnt worthy of recognition, but I think it is certainly an idea to thin it a little.

For example lock the topic as soon as it is created and then have simply 1 well moderated thread for bug reports.

[8125, K-JAM, P4300, MDA Vario ROM Development] mfrazzz:
Yep, I sort of agree... I'm about to work on the next release of XM6, but it basically is just going to be from the excellent Pandora Kitchen and packages, so was starting to question even releasing it (I may do some customizations to things, but really not sure). There are so many slight variations with minimal "custom" changes (other than splash screens) that pretty much any of these can be built by about anyone with minimal work (or thats the way it appears).

Faria and Doubleofour opened the cooking floodgates with their easy to use Kitchens. The Core and Pandora kitchens have just increased the proliferation.

mattk_r's work on providing a "Complete" solution (kitchen, excellent base rom, and tons of oem packages, and even cleaning up MMS and all and giving multiple versions) makes Cooking like a Instant Dinner. Just add the premade ingredients that you want, mix, and bake... Presto, your "perfect" rom just for you...
[8125, K-JAM, P4300, MDA Vario ROM Development] Hmoll:
While the shear quantity of ROM's is, perhaps, unneeded, I for one sure hope you release the next version of XM6! Part of the internet community's ideals is reuse. I surely appreciate mfrazzz's (and the others' he built on!) ROMs.
