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 )
Strange: At "LTE Band Selection" I get "FAILED" on every band.

I get the same on my non-carrier H815 running v20d-EUR-XX - when trying to enable individual LTE bands via *#546368#*815# - I get FAILED for every one.

DFS can see my phone but I cannot read or write anything

Enabling more bands on LG Urbane 2nd Ed Verizon W200V

Hi, has anyone tried to do this on a LG Watch Urbane 2nd Ed from Verizon? It comes with Band 13 enabled only and need to add Band4 for Mexico. Is this possible?
The AT&T version W200A has this enabled.
Thanks a lot.

Need help on tmobile H811

Hi.. I am new to XDA. I want to enable the LTE band 40 in my LG G4 H811 tmobile US version. I tried the steps you have given. But when i select Band 40 from hidden menu, it still shows "FAIL" only. When i retry "Read" in DFS tool, Band 40 is shown in enabled bands.
Please help me to enable band 40.
In your steps it is mentioned as "it's somehow necessary to flash HSDPA and LTE bands both in one go before restarting the phone". I need some clarification on this step. i am not sure whether i am doing this step or not.

Note: I have rooted my mobile and unlocked bootloader.

wich band would give me 3G? i dont undestand...i have 4G but would like to have 3G instead..

According to this awesome japanese guide - https://booleestreet.net/archives/8826 - we'll need to replace some NVRAM files to actually unlock LTE bands, along with modifications that was already done here, of course.
This all sounds very promising !

I want to enable LTE band 40 for 4G only. not for 3G. While click on Read in DFS tool, it shows enabled in LTE tab. But in LTE band selection, if i select Band 40, it gives Fail.
