@bruno said in BQ Aquaris M10 HD won't turn on [solved]: h am android package cause BQ don't provide an ubuntu package for the HD edition anymore. Afterwards i could reflash the device back to UT by using the UBPorts installer! Now i'm glad to have a running device and i stricktly avoid to power it down... Btw: after reflashing to android the battery power was only 1%. This after shutdown only 48h before. So the shutdown was defintly incomplete and the device drained the battery strongly. My question now: is this a BQ problem? Or is it a UT bug? I think your battery was drained just in time when you plugged it in. When that happened to me i could not connect it to my computer. Your reflash was most likely not necessary. Bug is with UT. Never happened to me when i used Android.
