Guide: Enabling LTE Bands

[coolguy71261]

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 !

Someone please look into this.

Tried this on Lg K20 plus

my LG k20 plus was sent down from the U.S to Nigeria, it is the metro pcs version it is was unlocked, but i discovered dat it didnt work with any of the 4g or 3g bands in my coutry, it only gets 2g which is really slow...
so i Tried this on my Lg K20 plus, with Android nougat 7.0, rooted, unlocked bootloader.
i was able to succeed in unlocking some of the hidden 4G and WCDMA bands but the problem now is i cannot get any network unless i put it on GSM only setting...
Can someone help with a better method for unlocking bands??

Will this work on an UsU-unlocked H810 G4?

on my h815, rooted,bootloader unlocked once i connected my lg G4 and installed minimal adb and fastboot, opened the cmd when i try to execute step 4 of the installation (Step 4: Make sure you have adb, and connect your G4 to your PC. In an adb shell, execute the following:
su
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable)the pc says me that su isn't a command or an exe......if i try to type echo 1> etc etc the pc says that it's impossible to find the directory....so i can't continue to unlock all LTE frequencies .....i'm so frustrating !!!!!

I found this to be a real pain. Try what I did and use https://play.google.com/store/apps/details?id=org.vndnguyen.shortcutmaster.lite

In the app select secret code Explorer from the 3 dot menu then find a listing that says hidden menu.

The band settings are in Field Test >> Modem settings

It takes some patience but you can set different bands to use.

Warning' you could screw up your device even worse

Cheers!

I also doing my h815 without luck. However, you seem doing under your PC environment. FIrst you need to log into your phone by:
adb shell
then your phone respond (most llkely with the prompt $).
Then,
su
Command prompt now change to #:
Next,
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable
Up to this point, I could do. However, I totally stopped at this point.
