Oneplus 6 stuck on 'unlocked bootloader' warning upon restart
-
@andorinhariver Okay, I've tinkered a bit with my device and I don't think this is a UT related issue.
I'm not sure really why, but the Oneplus 6 seems to just generally have a lot of trouble trying to boot to other OSes.
You just have to try and try and try over and over again.. would be helpful if there were logs of any kind showing what's wrong. Bafflingly, going into the recovery mode works just fine.

Im had a similar experience as well. Coming from a OnePlus One to a Oneplus Six that I received yesterday. T-Mobile Version. Messed around with it for most of the day, I was able to learn how to take it from the Tmobile version to the "International" version stock Android 9.0.11 version. From there I was able to push Ubuntu Touch on it this morning.
Switched over to dev channel (sad there is no Helium dev channel? ) and Updated to Version 511 under Dev channel. Rebooted and got stuck on the unlocked bootloader message screen. Rebooted couple times and same message - no boot into Ubuntu Touch
Just rebooted into Recovery, and the 3 spinning Ubuntu circles come up (believe it was installing the update), phone automatically rebooted, unlock bootloader message came up and then booted fine into Ubuntu Touch.
Checked and verified that Update 511 was installed.
Hope it helps someone

i think its the same issue mentioned in this post.It takes up to 12 attempts to finally boot into UBports on the OP6, just be patient, sometimes it helps to turn it on via USB cable, sometimes it helps to boot with volume+, and often its just retrying..
Oneplus 6 (A6003)
UBports 16.04 RC 2021-W32 -
Mine happens the same but with patience I go to recovery reboot for bootloader reboot again and if it does not start, I turn off and on with volume + power and at times it starts normally, you have to try the various options
-
@portu51 And you can reinstall again without format,normaly work
-
@magdesign Can you explain further? I have this problem. Do you mean I need to try and reboot about 12 times just to get the 1+6 to go into UT? Is that each time the device is restarted or just a one-time effort to get the device to restart into UT regularly?
-
@portu51 Is this an ongoing issue? If so that about kills any use as an everyday device.
-
I have the same issue. I flashed UT and things appeared to work just fine. As soon as reboot the device hangs on the warning screen and does not go to UT (or anywhere). I have read people's comments but nothing really seems very repeatable or logical of a solution in order to use the 1+6 as a daily phone if running UT?
-
@ronbillock - what works for me on my OnePlus 6t is to hold the volume up button and the power button simultaneously - and then it will boot into UT. Sometimes I have to do this more than once, but it eventually works.

@totalsonic Not for me. That puts me into Fastboot. From there 'Start' hangs me on the warning screen and 'Recovery' puts me on the Halium Recovery screen. I am tempted to select 'Factory Reset' to see what happens and maybe start over.
-
Not having the device myself I can only really use the the info on the device page. The help section at the bottom does give a Telegram group https://t.me/ubports_op6 that should be a good place to start for device specific help.

@digital_wookiee My Oneplus 6 has the same problem after I installed Ubuntu Touch. What works for me is I simply use the power button alone several times. To be precise, when the "Bootloader is unlocked" warning persists for more than 2 minutes, I hold the power button to turn off the phone, and then hold the power button again to switch the phone on. Two or three times usually does the trick, namely, the bootloader warning stays for only several seconds, after which Ubuntu loads successfully.
-
@toughcaddy P.S. This bootloader warning seems to get stuck when you choose the "reboot" option within Ubuntu on Oneplus 6. My advice is to always choose the "shut down" option in Ubuntu instead of "reboot" and then to use the power button to turn the phone back on. If the warning gets stuck, then use the power button alone several times as described above.

@ronbillock
Yes it is like this.... sometimes it will boot into UT on the first boot, sometimes on the 5 or so, and sometimes it takes up to 15 attempts..... it might make you a bit nervous in a stress situation but it will boot some time...
I am still trying to figure out any workaround, like connecting the USB cable, holding some buttons etc. so we could report a low-end trick to the devs
this should not be a daily usage breaker since you will not reboot your phone 100 times a day?
Edit:
As @fantastic_sky46 reported, the dev branch seems to boot better now... -
@magdesign The boot fix was merged into Dev last week and should be in the next RC update.
-
@toughcaddy I found a better solution than pressing the power button alone several times. First, enter the "Recovery mode" (not "Reboot to recovery"!) by holding the volume up and power button. When you reach the fast boot mode choose "Recovery mode" by pressing the volume up and down buttons and make your selection by pressing the power button. When in the Recover mode, select Advanced and then Power off. After that, try using the power button alone. If you still get stuck in the bootloader warning more than once, then repeat the Recovery mode procedure. With this approach, I never have to turn off and on my OnePlus 6 more than two times before it loads Ubuntu successfully.

@lakotaubp
Thanks,
switched to RC channel (on 04.Nov. 2021) and booting seems to work fine now!@toughcaddy
Just switch to RC channel or wait for the next release.@Digital_Wookiee
I guess you can mark the thread as solved or partly solved ... -
@magdesign Thanks, the Release Candidates worked fine for a while, but the latest small update (February 12 or 13, I think Ubuntu Touch 45, size 6 MB) resurrected this problem, I haven't been able to boot my phone into Ubuntu Touch for 2 days now. I have tried what worked before a hundred times, nothing works.

@toughcaddy
weird.
did you try to install stable with the ubports installer?
for me this always fixed stuff without loosing data on the phone. -
@magdesign You're a lifesaver!! Using my Ubuntu notebook and UBPorts Installer, I was able to install the latest stable OS, 16.04 OTA-21, without losing any of my previous data. It doesn't get stuck in the bootloader warning.
