@formel No, I elevated the command prompt in windows Powershell using ./ and it has always worked so I have never used fastboot flashing unlock_critical on this device. Most of the times I have installed using Windows with no issues. Have you upgraded to Noble (24.04.1.x)?

Imagine you only had one hand to work with. It's not beyond the realm of possibilities.

That is one scenario, but with a big screen device you would struggle to get across the screen in some scenarios one handed too.

@PringleMingle Have you put it onto the required version of Android before installing UT? Was the device fully charged before starting the process? Noble (24.04.1.x)does not work on this device so use Focal (20.04) instead. Someone is working on this to get the upgrade to Noble.

From experience a crashdump is usually a weak/dying battery or battery requiring a charge.

@penserv What tablet are you using? If the tablet is running Windows there is a possibility of dual booing Ubuntu. I

@Shriharsh-Kulthe It is an old phone (with the micro USB port) and the fact it updated to Noble may indicate further work may be done. It is not a common device though and I did use it for my main UT device for a while.

@Shriharsh-Kulthe Go to the devices page and scroll down to near the bottom of the Asus ZenFone page and have a look on the Gitlab pages by following the link. You can also contact the maintainer, they may/my not reply. If it is working on stable, it is working, you don't need anymore unless you have found a bug or are developing ...

@undrwater It's called having two hands. It's like a browser, Chrome's back button is hidden so you have to have two hands to use it. I think that would come under "nice to have" so it would be way down in the priorities of development unless the app developer decides to do so. For one handed gestures, large screen phones and tablets have their limitations.

@Moem I remember that a while back, I cannot remember which device at the time, but have duly forgotten over time, mainly thanks to the ludicrous way you have to unlock the bootloader on an Xiaomi device!

@KJU in a word, no. It is down to CPU architecture, the UT installer won't run from an arm device.

@shengchieh It means USB Debugging is enabled...

@Vlad-Nirky Yeah, there is only daily at the moment. I have researched this issue and albeit not common, it is there and something to be aware of.

There is a bug with the Nothing Phone (1) "spacewar" where SIM1 is not detected. This is NOT a Ubuntu Touch issue and looks like it is hardware related. On Android it shows as "SIM 1 is not allowed", on Ubuntu Touch SIM 1 is not detected at all. This only happens on some devices. SIM 2 works fine and has full data, VoLTE and 5G. See Reddit posts, XDA Developers and I have two devices suffering the same fate. This is not a bug, more an unpleasant surprise.

@muskist No, the device must be in EDL mode. I have never got the tool to run in Linux yet, Windows only unfortunately.

@Mario.CH 5G works on this device. Tested and working.

@Futura Doing a bit of research, Fairphone seem to have been strangled by Qualcomm with the use of EDL, unfortunately you have to send it back to them to repair - another reason I won't buy a Fairphone as that part is just not "fair" - you should be able to repair your own device!

@Futura The low level flash tool doesn't work with a VM, even with USB passthrough. You need a Windows machine, running windows as the OS. The EDL cable is handy, but not really necessary.

@formel Can confirm it works as well. I have installed it successfully on TB-X306F and TB-X306X multiple times to breath a better life into these older tablets.

To help you, you must have the following before attempting the UT install:
a) A TB-X306F or X that is the 4Gb/64Gb version - that gives you the best experience.
b) A return to Android strategy - You need a windows PC and the Lenovo Software Fix tool - by far the easiest way to restore a Lenovo device is with this tool.
c) Decent USB-C cable
d) The tablet has to have Android 11 running on it for technical reasons
e) The latest version of ADB and Fastboot installed on the PC - Windows had an issue with FastbootD (not fastboot), but it has sorted itself out now and works.
f) Patience and leaving things alone. Moving the tablet when things are going on can cause a loose USB cable to move and stop things working.
g) This tablet on the installer does everything for you with minimal interaction, as above, leave it alone and things take time, the reboot from fastboot to fastbootD can take a couple of minutes and the reboot from fastbootd to recovery can take 2~3 minutes. Be patient and persevere.

I hope this helps, but do make sure you have the TB-X306F 4Gb/64Gb version.

There is a Telegram channel for this device here as well as help with installation here where you will get help and quickly.

@tacetion so is it up and running with UT? A prototype is well worth keeping, collectors may seek something like that out..... It could also have had a screen replacement...

@kugiigi After researching I have come to that conclusion. If it had UT on it it may have been a one off experimental/test/promotional device. Check this out.

@PianoStudent4569 That is usually the sign of the incorrect Android version being installed. You may have downgraded to Android 10, but there are versions within that.
