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.

@kimo There are many great phones out there for Ubuntu Touch and asking a question like this you may get confused with varying responses, but here is my bit.

Volla Phone and Fairphone are expensive for what they are. They may lead in free and open source software, but there are cheaper phones that work with Android that lack the foibles seen here and in other forums as well as working with UT.

The easiest to install on and most things work is the OnePlus 5 and 5T. The 6 and 6T follow close behind. The bootloader on these devices is straightforward to unlock and a soft bricked device can be recovered without having to go back to the manufacturer.

Xiaomi phones are a pain as they make it irritating to unlock the bootloader, but they have solid hardware. Redmi Note 9 Pro is a great start and is well supported. I am partial to the Redmi Note 7 as I used it a lot, good screen, but voice in calls was a bit flakey.

The OnePlus Nord N100 and N10 5G are good solid phones too and well supported, again most things work.

OK, here is the disclaimer. most devices have requirements to install UT, such as downgrading or upgrading the Android ROM that must be stock. Some are more difficult to install on than others (the Pixel 3a/3aXL was not a 100% straightforward install without a bit of working out). The Asus ZenFone Max Pro M1 and Xiaomi Mi a2, were and are a bit of a challenge to get UT up and running, but work well.

So you can see there is not a definitive answer, couple that with what is available in your region. If you have money and want UT preinstalled, Volla and Fiarphone are the way to go.

If you don't want to spend that amount and want an easy install, I recommend the Oneplus 5T.

If you are in North America and require VoLTE, the Xiaomi Redmi Note 9 pro is going well on that.

Ok, to install on this device:

1. Boot into Android, enable Developer Options and enable OEM unlocking and USB debugging.

2. Ensure you are on Android 11 and your device is the 4Gb/64Gb version.

3. Open a terminal on the PC - if using Windows go to the folder where ADB and Fastboot.exe are and right click, Open in Terminal.

4. Plug the device into the PC and in the pop up window accept and then type in to the terminal on the PC, ADB reboot bootloader. This will boot you to fastboot mode.

5. Once in fastboot mode type in fastboot oem unlock or fastboot flashing unlock and follow the onscreen prompts. Once you have selected to unlock, the screen will freeze. Hold the power button and let the device reboot.

6. Set up Android again. Enable Developer Options and USB debugging.

7. Fire up the UT installer and follow the onscreen prompts. I suggest installing Stable 24.04.01. When it is installing, leave the tablet alone and allow it to do its thing.

@as1234 Thats the first bit. You then have to boot to fastboot and unlock it there running the command in terminal of the PC fastboot oem unlock

@as1234 Is your bootloader unlocked? What version of the tablet is it - 2Gb32Gb version or the 4Gb/64Gb version?

@rheomie Press power button and volume buttons together for at least forty seconds or until the device reboots. If not leave it on charge for a few hours and try powering up.

The system pushes the Noble upgrade to devices running on Focal, but don't seem to work with Noble. The specific example I am talking about is the Lenovo Tab TB-X605F/L 3Gb/32Gb version. The upgrade notification appears, upgrade and it just boots to recovery after installation. Running it through the installer results in the same thing. (Yes I know this tablet is a problem child). Would it be possible to stop this and/or remove the upgrade path for Noble from the installer?

(Similar things mentioned with the OP Nord N100 and OP Nord N10 5G, installer is fine with them).

Is the installer now working with Apple based Silicon Macs (M1 - M5) as Apple have just released the M5 version?

@robinsing the software fix does it for you, follow the instructions. You need to create an account or login with Facebook or Google account. You must also have your devices serial number to match the firmware.

@robinsing Use a Windows PC and the Lenovo Software Fix Tool to go back to Android. It is the easiest and quickest way.

Performance is not great, but it is far better than Android 10 and 11 for which I had to tweak to stop getting black screens when doing stuff.

@rheomie Delete all the files in the C:\ProgramData\RSA\Download\RomFiles folder labelled "TB_X306X_S120712_230301_BMP", but not the folder.

Replace the deleted files with files from your downloaded version (Android 11 and make sure it is Android 11).

(My version which I downloaded was Android 11 and was a folder labelled: TB-X306X_S230973_240402_BMP)

Then recover the device and you will get Android 11 installed. Then you can install UT.

@rheomie You need to delete all the files in the folder and replace with the Android 11 files for the 4Gb/64Gb version. This is the version I used: TB-X306X_S230973_240402_BMP. If you know the firmware file is Android 11 from the your downloaded version, extract it all and copy all the files in the extracted folder Firmware into the blank RSA\Downloads\RomFiles folder.
