Ubports installer issue - OP5T

[alextcranglesim]

Hi,

Unsure if this is the right place to create a ticket, so please let me know if it needs moving somewhere!

After reading the great progress of the OP5T port, especially the installer handling TWRP in the recent forum post, I decided to give it a go with my old OP5T.

Enabled developer mode, usb debugging and oem bootloader unlock; the installer correctly found the device and asked what I wanted to install.

After selecting firmware (as it was recommended) the installer crashes with error:
Error: core:download: Error: core:download Error: Error: Download Error: https://deac-ams.dl.sourceforge.net/project/crdroid/dumpling/6.x/firmware/firmware_9.0.11_oneplus5T.zip Error: certificate has expired

This is an issue raised on github: https://github.com/ubports/ubports-installer/issues/2422

Is it a case of just wait patiently for a fix?

Many Thanks,

Alex

@alextcranglesim Does it actually crash, or does it just throw an error message that has the option 'Ignore'? If it's the latter, just click 'ignore'. I've flashed that phone recently and it worked.

[alextcranglesim]

@moem hi! Thanks for replying so fast, it has an ignore option, I just didn't want to click it and not have the recommended firmware installed. It works by simply clicking ignore?

[Moem]

@alextcranglesim Yes, for me that did the trick.

[alextcranglesim]

@moem Thanks, I have clearly made a mistake somewhere - in the android developer settings, I have enabled OEM unlocking, but if I click ignore on the error above, the device reboots to bootloader and says device state - locked and my only options are start phone, turn off phone, and restart bootloader.

Thanks,

Alex

Please try without the Oneplus firmware upgrade (uncheck the box). Its an optional step to bring some firmware to altest version, but will also work without.

[flohack]

@alextcranglesim No do not ignore the error but uncheck the option before installation begins also:

• If your device ran Android before with an ecrypted partition its good to format data with TWRP before, to really ged rid of that for sure. The installer has issues removing encrpyted partitions sometimes

[alextcranglesim]

@flohack Hi! Thanks for helping out - it previously did have encryption but I did a factory reset in the hopes that it would have cleared that out. I have no real experience with using TWRP, I have been following the progress of ubports via my BQ E4.5 but as that is basically a brick now, I decided I should give it a go on my old OP5T. Do you have a guide/link somewhere to using TWRP to remove the partition? If not, no worries!

Thanks,

Alex

sidenote: the .zip it tries to download can be downloaded through a PC, so I'm not sure why the installer can't reach it.

[alextcranglesim]

@flohack If I try without ticking the box for the latest firmware, the device reboots to the same bootloader screen which says device state: locked
the ubports installer shows flashing firmware, instead of rebooting device - but nothing appears on the phone apart from the bootloader menu - so I suspect nothing is happening.

Then that is the problem. You will need to unlock the bootloader first. The duck knows how.

See, you did enable unlocking the bootloader; you did not actually unlock it yet.

[alextcranglesim]

@moem ah thank you! I knew itd be something stupid, I'll take a look later thanks again both for the help!

[alextcranglesim]

After moving to using a mac, the installer ran successfully (it doesn't work with the firmware ticked though!)

So what am I missing without that firmware, and will it be possible to re-install at a later date with that firmware included?

Also is it possible to re-lock the bootloader after installing ubuntu touch, to remove the screen that appears on reboot?

Thanks,

Alex

@alextcranglesim

Hello, yes you can reinstall it later it's not an issue.
What you're missing are vendor's updates on some firmware.
Featurewise I don't know what it means but probably not much.
Securitywise it's better to update as it often increase stability and fixes bugs.

Regarding the bootloader: you should not

No. The best way to deal with that screen is to look at it and gloat, because it means that you have freed another device from Google's evil grip. ️

[alextcranglesim]

Thank you all for the swift responses!

I will enjoy my new phone - and check the installer every so often to see if the firmware updates are working!

@alextcranglesim
If your phone gets OTA updates, you don't need the installer anymore for normal use.
Just wait for any update release (like coming OTA22 the 18th february) to be announced here and then go to phone settings and then "updates".

Edit : sorry i didn't see that was relative to vendor firmwares, not UT

[alextcranglesim]

Hi,

I was advised on the github for the installer to try the latest installer to get the firmware working.

The installer had no errors attempting to download the firmware, however when it tries to install the OS the phone turns off. (installer gets to rebooting to bootloader)

Current OS is ubuntu touch, developer mode is enabled & bootloader is still unlocked.

It is recognised in ./adb devices
However the same issue occurs when running ./adb reboot fastboot - the device powers off.

Any ideas?

Thanks,

Alex

@alextcranglesim Can you put it into bootloader manually and go from there. Hold power and volume up (iirc) go to fastboot and the installer should then do the rest.
