Fastboot: booting...FAILED (remote: bootimage: incomplete or not signed)finished.
- 
 @advocatux when the installer tells me: press the volume down button first and then pressing and holding power button as well. 
- 
 @josepjc I see you have filed a bug report (*) already, let's wait to see what the experts have to say about it. 
- 
 @josepjc wait, are you using a VM to do the installation? 
- 
 @advocatux no  
- 
 @josepjc right, then let's see what the devs have to say 
- 
 I can access to the recovery mode and I have a SD 2GB 
- 
 When I put de SD I can't access to the recovery mode, black screen... 
- 
 Hello, 
 this issue is still relevant for me. The workaround with the installer 0.1.12 is just to ignore the wrong image or whatever error occurs. In version 0.1.15-beta I can still not get beyond rebooting in fastboot mode.
- 
 @humungus what OS is running on your computer? What installer package are you using exactly? Do you have adbandfastbootinstalled on your computer? Have you tried to run the installer withsudo?
- 
 @advocatux Hello I seemed to have fixed the issue. It is not a tool problem, but one of the installer. The tools are called asynchroniously and eventually hindering each other. I will clean up my code and send the patch to the maintainers. 
- 
 @humungus perfect, I'm glad you found a solution  
- 
 I'm eagerly awaiting this update too. After a failed attempt at flashing 16.04/rc I had to resort to flashing a Fairphone Android stock image (urgh!) Is there a .zip of the current 16.04 image I can flash manually, preferably with a "flash all" shell script? I'd be more than happy enough with that in the absence of a functioning ubports-installer. 
- 
 Hello, afaik the zip is build on the fly from the archives on the recovery system. I did not find a complete zip.

 @scott-marley you can see here http://system-image.ubports.com/ how the system images are organized. If you have trusty or xenial [*] running on your computer, you can try to install UT using the command line. You can also try to install that tool on bionic too, I heard it works but I haven't tried it myself on that distro. sudo ubuntu-device-flash --server=http://system-image.ubports.com touch --device=FP2 --channel=ubports-touch/16.04/rc --bootstrap --wipeEDIT: I've just remembered that that method worked on other devices but FP2 on the early days of 16.04 development. I think that's fixed now but I wanted to tell you. Anyway, you can give it a try. [*] ubuntu-device-flashis only officially available for those releases

 Hi on bionic I can not get ubuntu-device-flash (I am on aarch64 arch). I did not find the sources neither. I commented my fix on github. Best regards  
- 
 @humungus ah I didn't know you're using aarch64  
- 
 Not sure if it helps, but in the Fairphone forum there were some instructions how to sign TWRP images so that they can be used for a one off boot (without installing). It's basically this: https://z3ntu.github.io/2017/06/16/Signing-boot-images.html I tried to fiddle around with the ubports-installer sources and added some debug output to see the exact command that fails and gives the "FAILED (remote: bootimage: incomplete or not signed)" error: fastboot boot "~/.cache/ubports/images/FP2/boot.img"If I sign the image according to the link above and use that instead, I don't get the error. Edit: it seems this is already being worked on https://github.com/ubports/ubports-installer/issues/184 and the problem is not with the file being signed or not. 
- 
 @josepjc , @Scott-Marley : 
 I also had to reflash my FP2 with android stock image, because the ubports installer version 0.1.13 "broke" it.
 After that I used the ubportsinstaller 0.1.9 and it worked like a charm...
- 
 Cheers for the advice everyone, I also stumbled with the unsupported "ubuntu-device-flash" in bionic, but as @Luksus also mentioned, v0.1.9 worked fine for me too (eventually, took a couple of goes). I'm now on 16.04/rc and just now got the W26 OTA update.  
- 
 Hey, 
 in github is stated that the issue might be fixed. Maybe you can give it another try. I will do so later.
