Dear all...

After skirting round the forums and doing my best to help (I am not a coder/hacker/programmer), I thought I would give some advice for people coming to Ubuntu Touch (UT) from Android based ROM's. Most of you are looking to install UT on a spare device or looking for an alternative to Android to use as your main device (daily driver), so you kind of want your device to function like and Android device which I get.

UT is open source and maintained by people in their spare time, hobbyists, enthusiasts - people from all walks in life who have interests elsewhere. This means that a device may be well maintained, may not be, may full of bugs and so on, so before jumping in to install on your device, please:

1. Make sure it is on the devices list

2. Check the maintenance state of the device

3. Read through all the issues. If you want fully functioning telephony and there is no sound in calls for your device, then don't put UT on and/or look at a better supported device.

4. Plan ahead - backup anything you want to keep, make sure you read up on the device, read @Lakotaubp Frequently asked questions, read the forum pages for the device you wish to install UT too for tips and tricks to install, that are not always clear.

5. Plan ahead - plan and think what to do if UT fails to install with the installer. Have you installed the correct version of Android? Is the bootloader unlocked? and so on...

6. Plan ahead - download and keep the version of stock Android that is required for UT and look at how to install it, in case UT is not for you and you wish to go back to Android. This should put any partitions that have been resized back to the original size.

7. To run UT, the bootloader on the device has to be unlocked. Google search (or whatever your search engine may be) for that particular devices way to unlock the bootloader. UT will NOT install or work with a locked bootloader.

8. If for whatever reason you return to Android my advice is and the consensus of opinion from other forums is DO NOT RELOCK the bootloader. This can brick the device, i.e., render it useless, unless you get a new motherboard or split it for parts.

9. If i didn't mention before plan ahead and read up on what UT is all about.

10. There are reasons why you have to install a particular version of Android in order to install UT. This is usually down to Vendor BLOBs (ie think of it as drivers for the hardware and on devices a lot of these are closed source (proprietary)).

11. Follow the installers instructions.

12. Keep it simple. Use the installer, that's what it is there for. Even if you are good with the command line, the installer can make it easier. It can also make it easier to back track if any issues arise.

I have too many PC's and devices (as my other half continually reminds me). I mainly use windows 10/11 to install UT (I need M$ stuff - being polite - for work) which works the majority of the time so I install Android Studio and update it -

13. Have the latest version of Fastboot and ADB drivers installed on your PC. This resolves a multitude of issues. I install Android Studio to get the latest versions. You don't need to, but my advice is that it does help.

My go to Linux is Ubuntu as it works for me, so I have a low powered Ubuntu machine to install to certain devices if Windows fails, but that is me.

14. Your PC (inc laptop) which you use to install UT to your device, make sure the operating system is up to date, nothing worse than in the middle of pushing UT to a device the PC reboots after an update (thanks windows).

@UBportsNews Please don't apologise for this issue. it happens. This is done by volunteers in their own time and is way above what myself and others can do, for which myself personally am very grateful for. Please keep up the good work it's greatly appreciated.

Just found Tweak Tool for Focal and the parts I use are working, yeah.... :beaming_face_with_smiling_eyes:
Many Thanks to Imran Iqbal for this most useful of apps!

I have held off on this thread, but I thought I would put my bit in now!

Bought 2 x BQ Aquaris e4.5 when Canonical and BQ put them on the market that day. One was mine and the other was mine too, but I handed it out for people to play with.

As a phone, text, MMS, camera and web browsing, most used and thought it was adequate. For social media, it was no and a resounding no at that.

Ok so come to 2022/2023. Canonical has devolved Ubuntu Touch to the community when the phones and tablets did not take off as planned - you have to try these things! So now Ubuntu Touch is run as a charitable foundation (UBports) by volunteers. There is some commercial working from what I can see, but most is run by enthusiasts and volunteers. This means your data is not going to be scraped and sold to the online bidders so you can get spammed with ads (thanks Amazon, Google, Apple, Xiaomi......). It also means that some things work, some things don't and it is not for everyone as they want a device that just well works for what they they want.
Some things won't work as UT is open source, i.e. Internet banking apps (encryption), Social Media, such as SnapChat and Whatsapp and so on. (BTW this is my opinion from what I have observed and read).

The Browser issues has been strongly covered with reasons why Morph is used and not Chromium or Firefox, but I find Morph overall very usable and suitable for me.

The Apps issues has also been extensively covered and again a lot are coded by volunteers and enthusiasts who spend their own free time and money running and maintaining them (kudos given for that). If you want an app that is not in the store, create it yourself, or use the browser, or heaven forbid, use your Android or Apple phone. It is that simple. What I cannot use on UT, I will use on my computers, or Android phone (my Iphone is out of Action, but was needed for one app).

I don't use Waydroid as I don't see the point personally (using UT is to avoid some Android apps), as I said if I need to use an app that is not in the store, I will use it on another device. But for some Waydroid is convergence with Android apps and I see why people are enthusiastic about it and again Kudos to the people setting it up and running with it.

Options, options and options, there are so many to do what you want. There is always a way and work around.

Thank you all for your hard work on UT and also the criticism as criticism makes things better in most cases.

Kind regards to all,
Mr T10001:zany_face: (I pity the fool).

Volla Tablet is launching tomorrow - 17/4/2024 on Kickstarter.

Got hold of a Oneplus 6. Running Android 11, so downgraded using OB25 build from here.
Unlock the device (open developer options by tapping build in about device until it states "you are now a developer", back to System, Developer options, enable OEM unlock and USB debugging). In a command prompt use ADB to reboot to bootloader and then use the fastboot command "fastboot oem unlock", then when done reboot the device and set Android up again. Set up developer options and USB debugging, set it file transfer and copy the OB25 file to the root of the device (i.e. not in a folder). Go to system update and check local update and tap the zip file. Allow it to do its thing and tap reboot when done. The set android up again and hey you are on Android 9!
Then just follow the UT installer.
Installed so easily, I thought it was a Nexus 4 (apart from the Halium splash). Less than an hour and it is up and running. Good device so far!

@daemonicvs It is more than that, it is about Lineage support and getting hold of Vendor Blobs ( a lot of vendor blobs are proprietary so they have to be reverse engineered - think of a blob as a driver in PC terms). It is the ability to unlock the boot loader so vendors like Huawei are out. It is also the ability to get the right Android on the device, some devices the Android version needs rolling back and it cannot be done without bricking the device.

And one of the main restrictions is having an enthusiastic person who has the ability and time to a) create the UT port and b) to maintain it.

@SpecterFortress This is a fantastic guide to installing on the Rabbit R1. I followed it, had to deviate some bits as even though I had rabbit.tech enable developer options, it didn't sync so I had to unlock it manually and booted to fastboot using chrome.

Not a question, but please give a shout out to Brian for his work on the App store:

Link here to new store

It is looking good. It requires testing still.

@snailc it is always best to use the ROM the porter specified, some may work, but most won't.

@MarcelloTogg what issues are you having? The MSM Tool requires a windows pc with Qualcomm USB drivers installed.

@Dieter42 Not yet, but the port has been taken on, so hopefully it will arrive....

@majorquibble Check this thread out on the Nord N100.

@linhmieu2 Before ubuntu.img is sent to userdata have you formatted it (to EXT4, being Samsung it should be EXT4)?

@linhmieu2 Have you flashed vbmeta.img?

@zeust No, just downgrade and then install UT.

@toniox EDL is different on Xiaomi devices. You have to use the MIFlash tool and use a MI account to log in (a complete f*&*&^$$ around to put it politely to get that done), then download the latest fastboot ROM for that device and I mean the latest fastboot ROM, unzip it and direct the MI flash tool to that. Hold Volume UP and Volume down together and plug the device into the PC and it has to be a Windows PC, MiFlash will not work otherwise, ensure you leave the bottom right box ticked for clean and install, do NOT lock the bootloader. Then start the process. If it fails, keep trying, it will work eventually. Unbricked my Mi A3 using this and it took a lot of attempts.

The other EDL mode is mutch the same, but requires opening the back, removing the mainboard cover and shorting the two EDL points, which requires fashioning a tool to do so so you can short the points and plug the USB cable in without requiring 4 pairs of hands.

EDL mode should work as it is the lowest point of entry to reflash the stock ROM and as the phone boots with that dialogue it should work.

What I cannot understand is an Xiaomi repair centre couldn't do this procedure! Any pro repair shop should be able to do this.

The other alternative is to buy a broken one and swap mainboards to get a functioning device.

It depends how far you want to take this.

@0xecution3r Yeah they wear out over time. I have replaced the ribbon cable and buttons on a lot of used devices. You can mark this topic as solved by marking it as read and then solved.

@linhmieu2 Could that be the issue, you have built of LineageOS21 (Android 14) and used Halium 14, however as far as I know (which is not a lot with porting) UT generally likes a stock Android ROM.

What version of Android was installed on the device?
