Lenovo TB-X605F Installs fine but doesn't boot

stevetheobscure

So I have tried this a few times now and the UBPorts Installer always seems to install fine, but it goes to a boot loop with the Lenovo logo. It will stay like this forever if I let it. I've let it go for a day, 2 days. The installer doesn't give me an error, I've left it to charge and not touched it, I'm kind of at a loss now and thinking I either have to get a Pinetab or give up on this. Can anyone help me?

@stevetheobscure you try to install the version 20.04 of UT (it's seems, it is not possible to got a working 24.04 version).
And also how many RAM in your device ?

stevetheobscure

@libremax 3GB ram. I did 20.04 the most recent time. I did read that 24.04 wasn't booting and I did try to install that twice until I found that out. But 20.04 is the devel release and I didn't think that would work terribly well either and it didn't the last time. 16.04 shows as the last stable version so should I go all the way back to that?

@stevetheobscure The TB-X605F and X is functional on 16.04. On 20.04 there are things not working, mainly the cameras. On 24.04 it is not working (yet?).

This tablet can be a nightmare to boot, but with patience I have got there on all of mine. For some reason, some will boot and reboot absolutely fine. Others will just hang at the Lenovo splash screen and take some techniques to get booting, that are not software tweaks..

@MrT10001 do you have any tips? I'm planning to run fastboot continue on it to get it to force boot to see if that works. I've seen some people say it can take several attempts.

@stevetheobscure Tips:
Follow this and be patient, very patient...

First off, run it through the installer and install Xenial or Focal. If it boots into the OS, great, don't power off and leave it charged.

If it hangs though, at the Lenovo splash screen, this is the patient part....Follow these steps....

Power off.
Boot to recovery
In recovery Format data and cache, Mount the system and reboot to recovery.
In recovery now mount the system and reboot to recovery - do this at least eight times on the final time reboot to the bootloader.
Connect to the PC and with command prompt open run fastboot continue, leave it for 20 seconds, if no boot, power off and boot to fastboot and repeat this step four times.
Still no boot after step 5, boot to fastboot and run the command fastboot reboot. Do this at least four times, but by now, it should boot.
if the above steps fail, leave it for an hour and repeat.

It took a while for me to work this out, but it has worked every time on these tablets, I was just very patient.
