Installing - connection to device lost
-
Hi,
This is the first time trying to install UBPorts on my old Oneplus 3T.
It had the stock OxygenOS 9 and not rooted.
I first tried the Windows installer. That seems to be completely broken as it says it can't talk to UBPort servers.
I then moved to linux and tried both Snap, deb and appimage and get further but get the same result.
When it says its pushing the files to my phone. On the phone itself I have a yellow text Android Recovery screen.
But I get the following message just over half way through. I've tried 2 USB cables I'm almost certain that it is not loosing connection due to a bad cable or port.
Can any please help?
What log files do i need to be looking for to get more info? -
@mikeglover first flash twrp and format data to EXT4 and wipe cache and system.
Edit: or first wipe and then format...?

Known issue, under watching, see : https://github.com/ubports/ubports-installer/issues/1847
You can try with last working version : https://github.com/ubports/ubports-installer/releases/tag/0.8.6-beta

@thilov Thank you. That did the trick.
Needs a step in the installer to say to install TWRP then as I didn't know about that.
Phone is now setup and working good so far.

@mikeglover Hi, I am currently facing the same issue. I formatted, wiped, formatted again, wiped in whatever order you can imagine, but the result is the same. "Connection lost to device".
The cable is OK, the USB port is OK, I have used them both to install a number of custom ROMs on a number of devices.Could you specify the exact order in which you proceeded with the UT install? (i.e., first format to ext4, then wipe everything eight times, then format as ext4 twice)
Thanks in advance.I have seen a number of posts about this issue. Someone said that the install failed because the only ext4 partition was "cache", and it fills up quickly. However, I reformatted data, system and cache to ext4, countless times, so this suggestion did not work.
Somewhere else I read something about the data partition being named "userdata", and that you have to format it directly with fastboot [ fastboot format:ext4 userdata ]. Tried this with "data" and "userdata", to no avail.
The install goes as far as leaving the UT recovery on the phone, but it does not progress from there.

@en-ragegit It should all be avilable in the advanced wipe section of twrp. Wipe data and cache format to ext4. Some even wipe system .

@lakotaubp
Thanks for the reply. Yes, I am familiar with TWRP, I have applied the wipe and reformat functions. My inquiry was about any potential specific order to apply each step, and even if you have to repeat a few, reboot TWRP in between, because I have tried plenty of times, interchanging the order, repeating steps, all to no avail.Tried the .deb installer as well as the appimage.

@en-ragegit from what I remember in that order wipe everything then format. Then I used wipe and bbotstrap option on the installer with the devel option. Then there is the normal advice on trying another cable or two. Good luck.

Hi @thilov, @mikeglover
Would request you to kindly the steps and the sequence in which the Format/Advance Wipe should be used to successfully install UT on OnePlus 3T.
I've tried every sequence possible and those mentioned on the page.
I have the same observation as @En-Ragegit .
Also do mention the installer version, TWRP version etc.
The installer is able to successfully install the Oxygen OS but not UT using the same cable. On installing UT the process ends up saying "Connection to device lost".
Also if there is any manual step to perform the installation ?
Best Regards

No matter what version of twrp I used, this workd for me:- format Data to ext4
- wipe System, Dalvick, Cache and Internal Storage.
-
Thanks @thilov
Trying it now.
-
@thilov what about the OS ?
I mean if a previous installation failed, do I need to install Oxygen OS and then follow your steps or can continue directly after failure ? -

@geekyneo You don't need to install Oxygen OS. Just try it again.
From which distribution are you installing? Some failed with Linux Mint. -
@geekyneo Oh, you are using Windows.... Please try Ubuntu. No installation is necessary. A live system is enough.
-
@thilov It's linux Mint(based on Ubuntu). It's not windows...

@thilov , I can confirm that it's failing for UBports snap installer 8.8.0 on Ubuntu 20.04 live machine, with device on Oxygen OS 9.0.6.
I've followed all the wipe/format step as instructed by you. -
Just as a thought is that version of Oxygen ok for the OP3/3T or would an older version be better. Can't think why but are the partions off in some way? Probably nothing to do with it and the answer is easy but lost for now on this.
