I have an Aquaris E4.5. Following the latest update, the software went bonkers and would get stuck with the Ubuntu logo on boot and then hang at that point. I am attempting to reflash the device (having done so multiple times previously with success) but I am receiving an error message on doing so:

ubuntu-device-flash touch --channel ubuntu-touch/stable/bq-aquaris.en --bootstrap --recovery-image recovery-krillin.img
2016/10/31 15:51:34 Expecting the device to be in the bootloader... waiting
2016/10/31 15:51:45 Device is |krillin|
2016/10/31 15:51:45 Flashing version 35 from ubuntu-touch/stable/bq-aquaris.en channel and server https://system-image.ubuntu.com to device krillin
can't flash recovery image

I have no idea how to proceed. The phone is apparently successfully booting to fastboot but then there is this error message.

So, if nothing helps, try the android flash tool. It will complete reset the phone (beside you unselect the userdata.img for keeping apps, settings and userdata).



Attention: First click download and THEN just connect the device via USB.

  • Hey, thanks for that. It worked great. I tried the simple download first without success, but then I set it to format first followed by the download, which worked. Thanks! It's good to know of this alternative approach.
