My g'ness... I just, barely remembered it... phew! So that's taken care of from a functional perspective.

@shapley Up near the start is a section on flashing twrp with fastboot then using that to reset/fix cache, system and data. After that just rerun the installer and all should be ok.

@Flohack thanks a lot for helping me open my eyes.

I still don't understand the difference in vendor files but android_device_oneplus_bacon-1 seems indeed to be used for building the images.

Thank you @Ingo. I've added it to the code and it works.
As this is the reboot approach I'd still leave the issue open as maybe someone might come up with the preferred refresh solution.

@normandc Thanks, this hack works for me 😉

Was Android > 5.1 installed before? You might need to go back to stock Android from an older verison to get the cache partition right.

@dbosley No problem. All sorted.

@Lakotaubp Good to know, I’ll try that if it happens again. Thanks.

@Stefano Thank you for the advice. I'll try asap.

Use SSH {PuTTY on Windoof} or ADB to login into phablet's shell, export the sqlite DB as indicated and move the files to your PC, use notepad or gvim to read them.

@lduboeuf Good idea. There have been several on this topic over the years and all seem to end the same way though, no conclusive fix, yet. @UniSuperBox has pointed to a good starting point https://github.com/ubports/ubuntu-touch/issues?utf8=✓&q=is%3Aissue+is%3Aopen+mms

@guru The drawback is that if we do not mark messages as read, your unread count will explode: All groups and chats will show the blue bubble with 999+ unread messages after some time. You will not know which message you have already seen and which not. How will that work?

Telegram server expects in order for you to keep track of unread messages (and also positioning the view when opening a chat on the last unread message) that you submit read receipts. They will be relayed to all other parties in this chat, if needed. You cannot influence this.

I will not implement a "shadow db" that keeps track of "locally read" and corresponding network messages, since that defeats the purpose of the tdlib library which encapsulates the whole Telegram protocol and also message store for us. You m,ight however want to file an issue here: https://github.com/tdlib/td/issues - those guys could in theory provide an option to not send read receipts.

Again I expect they will refuse, since if its not implemented on server side, its complicated and unreliable.

@dobey Thanks, yes, that makes sense. It would be great to have the same basic set up on various devices. One good thing about Ubuntu Touch is that the MTP set up with a desktop is far smoother than it is with Android/LineageOS.

@todrab 15sec adb from XDA developers is best for windows installed system wide. That might have been an issue.

@Pingu it works - cool !

@dobey Oh right, I read bandwith instead of band.
Let say it because of lack of sleep 🎊😎
