    Ah, that one, yes, unfortunately that too is a fairy tale

    See, there's a keep-alive protocol between the APE in the device and the flasher executive running in the device, the same protocol BTW which tells the flasher to display the charging precentage on the window: 1%...2¤...3%... and so on until it finally reaches 11%.

    If you kick the flasher with ctrl-C, it will break away from the loop in the device, too, and it will reboot. (with the existing APE, of course, my mod is a bit better on that )

    impatiently waiting ...

    Blessed are the patient

    flasher -R? Sorry I got the case wrong in my previous post. I could have sworn someone once suggested that but can't find the reference now.

    I should let juice answer, but:
    flasher -R
    will boot the device up.

    I do not know exactly when charging kicks in but from my experiences I would expect that the left juice in battery is not enough to load/execute kernel and get the device to the charging state even while it is connected to (USB) power.

    I know, but will it boot it up right away or after the battery charge reaches some threshold?
    I guess I could try it myself but how do I get the battery to such a depleted state in the first place?

    For me charging didnt kick in with only flasher -R, it'll say device not recognized. Only with the main.bin string it will say to charge the phone. But some other time the scarywarningmessage(c) didnt show up, boots into juiceme's ubiboot and it boots Harmattan while charger immediatly was plugged in.

    It's a damned DOA phone but i like it.

    Using Nitdroid or even juiceme's ubiboot console should get you into such state (if you really like).

    But I think vincr already gave the answer.

    Yes. And I love it too. And even more the N950.
    But at the end the N(eo)900 is the one!!!

    Had this like 5 times, you won't want this happen.

    But anyway, I like the OP way to charge it. Reminds me building weird dc suppliers for my beloved Philips K11 tv.
