Awesome! Another "powerful" device. Have you tried external display? I think this device supports it

[walidham]

@kugiigi don't have usb otg, will search for one and test

[trainailleur]

When I researched the h918 several years ago, there were concerns that the bootloader couldn't be unlocked it it had updated past a certain OTA. Do you know if that is still a problem?

[walidham]

for LGV20 don't support all fastboot command like flash and boot, so all time i use TWRP to flash halium-boot.img.

@walidham is the sound in calls working? Calling on to LG V20? 7.1 ports are having a problem with this, can you test and reply? Thanks.

[walidham]

@Stefano call work i tested it. Also got camera work 50%, photo 16mb , but can't record video

[Stefano]

@walidham Did you work/chat with @vince1171 about the calls sound? We need help with calls sound with OP3 as calls on to Op3 works, but no sound. Calling from Op3 works ok. Did you ever experience such an issue? Thanks.

[walidham]

@Stefano really can't test it now, my earspeaker is dammaged, can't found it her in my country, maybe will command it from aliexpress. but i tested last week and work but sound is very low, must change some xml config file to increase sound.

[walidham]

@Stefano i tested it now , yes there is no sound in ear speaker and high speaker

[Stefano]

@walidham you see, so we have same issue unfortunately

I've never flashed a phone but I have a h918 that I can use for this. Will the dd command work or do I have to install twrp? I cant seem to get twrp install on it.

[unklebonehead]

And that wont work either.
Think Im just gonna have to wait and buy the Pine phone community edition.

[arubislander]

@unklebonehead no need to wait. pre-orders are open now!

[unklebonehead]

Yeah I know they are open now. Just hope I can get the funds before they close. Lol.
But I would like to get it installed on this V20. I use it as my backup phone with my job as a truck driver I tend to break just about every phone I get.

[walidham]

@unklebonehead i will upload new version bugs fixed : camera.

[walidham]

@unklebonehead you can install using twrp.

[unklebonehead]

@walidham Thats my other problem. I cant get twrp to flash. I have the bootloader unlocked and when I try to flash twrp it starts and runs for a second and then fails. I've tried different usb cables, ports, different versions of twrp and I've also read that there is a problem with adb in Ubuntu 18.04 that adb doesnt work right. The only solution I found was to use a windows pc and that is not an option for me. I dont have access to one.
Any ideas on what else to try?

[walidham]

@unklebonehead you have h918 variant ? if yes you can't install twrp by adb , you must use lafsploit .
