I had this kind of problem, and to start the flashing process, I had to
plug, then unplug the power cable. The linux flash failed, the windows
flash suceeded and I get back my Nokia, after having spent a few hours
trying everything possible.

After a couple days of using my 770, I innocently turned it off and<br>took out the battery to read the product ID. Now it won't boot past<br>the initial "NOKIA" splash screen. I've seen others recover from<br>
similar situations by flashing, but I can't get to a point where the<br>WinXP or Linux flasher will talk to my 770. I'd really like to avoid<br>doing a warranty return, because I know my local CompUSA doesn't have<br>anything with which to replace it. Any ideas what's wrong and how to
<br>fix it?<br><br>My experiments so far:<br><br>1) Pressing and holding the power button for a long time, with or<br>without the power adapter attached -- nothing happens.<br><br>2) Pressing and holding the power button without the power adapter,
<br>then connecting the adapter while still holding the button -- the<br>display immediately turns on and the "NOKIA" splash screen appears.<br>The progress bar at the bottom of the screen never shows up. If I<br>
release the power button, the backlight goes off after a few seconds,<br>but in the right light I can see the display is still on and hung<br>at "NOKIA". It stays this way until I unplug power, at which point<br>
the display goes off. If I continue holding the power button rather<br>than releasing it, the backlight cycles at about 3s on/2s off.<br><br>3) Repeating the previous step with the USB cable attached to a WinXP<br>PC -- The PC complains that an unknown USB device is attached, but the
<br>device isn't working correctly. If I continue to hold the power<br>button, the display and backlight flash about once a second until I<br>release the button. At the same time the PC cycles USB plug-unplug<br>events until I pull the power adapter. I'd successfully transferred
<br>files from that PC to the 770 via USB before the 770 started<br>misbehaving.<br><br>4) Repeating the previous two tests, but holding the home button<br>before pressing the power button, makes no difference. Likewise for
<br>the menu, escape, full-screen and plus/minus buttons.<br><br>5) Attaching the power adapter with the unit off does nothing. The<br>charging screen does not appear, and the display and backlight stay<br>off.<br><br>6) Attempting to flash from a WinXP system – the 770 never comes up.
<br>The PC cycles USB plug-unplug events, and eventually complains about<br>an unknown USB device that isn't working correctly. I know positively<br>this 770 + USB cable + WinXP system combination worked before, because<br>
I'd used it to move files on and off the MMC.<br><br>7) Attempting to flash using the Linux flasher -- I first tried simply<br>resetting the device using flasher:<br><br>"./flasher -R"<br><br>That didn't work, so I tried actually flashing it:
<br><br>"./flasher -F Nokia_770_SE2005_3_2005_51-13.bin -f -R"<br><br>In both cases, I never got past "Suitable USB device not found,<br>waiting". However, I could hear the Linux system's disk churning a
<br>little about once a second when I was holding the 770's power button,<br>making me think my Linux system is seeing the same USB plug-unplug<br>cycling I got on my WinXP system. I tried all of the USB ports on my<br>Linux system, to make sure no internal hubs were getting in the way,
<br>and unfortunately the 770 behaved the same on every one. I also tried<br>both as a regular user and root.<br><br>This is the first time I've tried to flash my 770, although my saga<br>began when I took out the battery to get the product ID so I could
<br>flash-up to the latest release.<br><br>I also tried flasher's "-c" cold-flash option, but it wanted a serial<br>connection rather than USB. Anyone know the pinout to the connector<br>next to the battery? I'm guessing a few of those pads are the needed
<br>serial port.<br><br>8) I considered maybe the flash code on the 770 is clever enough to<br>check for a charged battery before allowing flashing to proceed. My<br>battery could be low by now. But I measured it at 3.78V
, so that<br>pretty much rules that idea out.<br>_______________________________________________<br>maemo-users mailing list<br><a href="mailto:maemo-users@maemo.org">maemo-users@maemo.org</a><br><a href="https://maemo.org/mailman/listinfo/maemo-users">
