Ah thanks for the info! I optimistically tried 22.2 again (20251011), still not working VoLTE not supported, 😠 (expecting the 23 I thought this might be the last 22.2, so wanted to test before 23) So going back on 22.1 (20250405)- where VoLTE works ☺️

As LOS 23.0 is now available for the Pro1X (see this), we can expect it for the Pro1 as well in a few days. Will try it ASAP and report back, if it is as useful as 22.1 or as useless as 22.2.

It will wipe it, sorry.

Strange as it may sound, the connection of fastboot is more picky than adb. Usually an older pc, a usb hub or a Linux OS seems to fix it. I primarily see the issues with Windows pc with an USB3 port. I got the issue on mine too, but even a USB3 port on a thunderbolt docking works. As an old tech guy it oozes of handshaking issues, that is a bug in the driver for Windows means it can not correctly handle if things goes too fast, and an usb2 port or a hub is enough overhead for handshaking to work...

I previously tried to report a bug - and frankly I do not want to to try that again. With neither calls on 4G nor multilingual keyboard working, and combined with ridiculous stamina, It is unusable as a daily driver for me anyway. for 22.1 it is only the keyboard that is messed up. And has been since perhaps 20.1 or even older. So more reporting the state here so others do not waste their time with it, than actually expecting anyone that can fix it to read it here,

I wish I had an answer for you for what is going on. I have no idea on how the legal construction/status is, and if any assets are left at all. The fxtec site has for long just redirected to some 'placeholder'-page, but some deep links (including this community) is still kept alive (AFAIK). I have no idea who is paying for them staying alive. I'm not sure if it was this thread or another, but a year or two back, some dug up info on the company from some official British site, and the company was still alive back then.

AFAIK stuff like flex-cables are custom, so highly unlikely to find. Best chance is to find a specimen with another bug and cannibalise it for the needed parts.

There can be some apps that will not work on Lineage - or rather the problem is not really lineage, but that they expect the phone to be locked, to reduce the risk of malware stealing your login.

Spotted a more important bug that could be related with the battery waste as we discussed earlier. With the same sim in the same phone at the same location, and set for LTE only, here VoLTE works just fine on 22.1, but not at all on 22.2. So 22.2 CERTAINLY introduced some important bug in handling of carriers and bands (the sim is TDC in Denmark).

Due to the changes @Hook reported here, I tried upgrading to 22.2 (again). Will edit this post in some hours with the result.... ADD: And it is completely USELESS!!! Went from 97% to 47% in short of 8 hours. (Idle overnight, as much as possible uninstalled/disabled,,,,) Will go back to 22.1, or maybe stock and just forget about LineageOS, that (like the AICP project) seems to have F.. itself up to a useless state... Went back to 22.1, though over four months old still much newer than Android 9 in stock....,

I would guess your best chance is to get a faulty unit on e.g. ebay. Note that the Pro1 and pro1x bottom parts are NOT 100%identical. They had to make some changes for the antenna they said somewhere a very long time ago. It has been awfully quite from fxtec for a very long time, so my guess would be that an official new one is highly unlikely.

I have not tried for a very long time, I just tried to adb reboot fastboot on the one on 22.1 and got a variant of the menu I've never seen before I can not remember what it used to fail with, maybe it was not until the flashing, OR something has been updated since last i tried.... On the one on stock the same command just reboots back into android. Booting into bootloader, it boots to android as soon as I attach a cable when in a direct port, but works fine in a port on the docking

Could you please test if it make any difference over night, if you turn VoLTE temporarily OFF? Just to test if VoLTE is somehow part of the issue. (I know turning VoLTE off will not be a solution, for carriers that shut down their 3G services. So just a test)

Really weird. OH just retested. VoLTE by this carrier now works! (TEST: selecting LTE as only band, restart, and do a call). Does yours (clam to) do VoLTE? It could be interesting to turn it OFF/ON. If it for some odd reason relates to the battery bug. @TeZtdevice do you have VoLTE ON or OFF?
