Hello,
I was on a custom ROM and tried to install UT according to instructions.
It is an OP3 in my case.

First I installed Oxygen OS, booted and enabled USB debugging, etc..
Ubports recognizes the phone when plugged in and also through the whole tutorial the phone was always recognized. Also Fastboot or then in TWRP no problems. but it does not go on pushing files. It always comes up with the message connection lost.

I tested it with Ubports-installer 0.9.5 on Ubuntu, also with xubuntu. Then also with an older version 0.8.6.

I have really tried a lot with the Telegram group, but unfortunately it did not work so far.

I have already tried Repair System. Then formatted to EXT4.
Device is unlocked.
Can someone maybe give me a hint how it could work?

Thank you

@wusa Have you read through all the thread above including about the not ticking wipe data and what to wipe in TWRP.

@wusa When you unlocked the device did you boot back into Android and set it up again?

If you mean the installer, yes i tried both versions.
First install and wipe data and
First install without wipe data.
Both runs into the same error.

No, first i installed OOS and set everything up.
Than i tried to flash UT. In Fastboot the message tells me the device is unlocked.
I unlocked the device years ago.

@wusa I found that devices would lose connection if I did not boot back into Android directly after unlocking and went straight into the UT install (trial and error).

I had an issue on a Oneplu3 where it would not load any ROM. I ended up re downloading the last ROM and installing it piece by piece in fastboot. This worked and then allowed UT to be installed.

I dont know which ROM was my last ROM i tried so many different custom ROMs my whole time i used the phone.
But i also tried to install TWRP through fastboot and i installed OOS again through the console in ubuntu.
Then i did the developer settings and connected my device.
Than i tried the installer again. Everything failed.

I dont know how to proceed now.

Maybe someone can tell me an order how to proceed step by step again.
What I should delete, how and where I should delete, etc.

@wusa Not just that. You might have to install TWRP and wipe and format cache, data and system to ext4.

@pranishres Great video. Successful install on OP3T A3003 (Europe model) with ubports-installer 0.9.7-beta. Had to switch Cellular Connectiontype to 2G/3G to receive calls. On T-Mobile in The Netherlands.
