Nexus one Froze, Vibrates 7 Times, Wont Boot

---

So my nexus one froze today, and now whenever I pull the battery and put it back in, it will vibrate 7 times and wont boot. Is it bricked, or what can I do to fix this?


Thanks

What were u doin when this happened and what does the boot animation come up

Sent from my Nexus One using XDA App

I opened up the navigation app and it froze. Puller the battery and had that problem. I then decided to pull the battery, press the power button a few times to discharge the phone and it booted back up. So hopefully it wont happen again

Same thing happened to me. I was experimenting with an undervolted kernel which up until then had been behaving well. Received a bunch of texts and notifications simultaneously. By the time I got to my phone, it had gone to sleep. I was able to power on, but the screen was completely unresponsive. The powering on was also very delayed. I couldn't shutdown with the power button so I pulled the battery.

It could only do a 7-vibrate boot/freeze every single time I pulled the battery and replaced it. Finally, with the above advice, I left it out for several minutes, hit the power button a few times, then replaced the battery and got it to finally boot.

This happened to me today too, I took out my SD and it booted up just fine after that..not sure what happened. I checked my SD for errors but it didn't have any and had no problems after I put it back in.

hmm havent faced these errors yet, have u modded the rom at all?

mine just did it now when i changed the sd card.
taking the card out doesn't help.
i'm guessing it thinks the battery is flat or something similar, will try charging.

edit: just kept trying and it eventually worked.

I have the same problem, hitting the power button does nothing, I leave the battery out for ~ 5 minutes and eventually get a fastboot screen and 7 times vibrate, but no control, power button, volume and trackball not working. I have to pull the battery out, wait another 5 minutes or so and try again.

Does anyone have a clue about what that 7 times vibrate means? sounds like an error code.

If after have pulled out the battery for 5 minutes I keep pressed the volume down and the power, I eventually have a fastboot working screen, but choosing recovery from the menu takes me back to the fastboot screen with 7 times vibrate. Taking the card out or the sim does not make a difference.

How did I get here: Was using Cyanogen 2.2, rooted, screen froze one day, pulled the battery out and here I am.

Tried to do a reset with volume down and power, it freezed during the procedure and now it won't boot at all.

I'm still able just to start in fastboot. Recovery and clear storage do nothing useful. Booting normally gives me the nexus logo for a while and then the screen blanks after a few seconds.

I can do fastboot flash boot, but I can't do fastboot flash system, it just says sending and that's it:

[root@ds1 apps]# ./fastboot erase userdata
erasing 'userdata'... FAILED (remote: not allowed)
[root@ds1 apps]# ./fastboot erase cache
erasing 'cache'... OKAY
[root@ds1 apps]# ./fastboot flash boot Passion\ Google\ WWE\ 1.01.1700.1_ERD79/boot.img 
sending 'boot' (2044 KB)... OKAY
writing 'boot'... OKAY
[root@ds1 apps]# ./fastboot flash system Passion\ Google\ WWE\ 1.01.1700.1_ERD79/system.img 
sending 'system' (116663 KB)...

Any ideas anyone ?

Since you said you were using CyanogenMod, I will assume you are using CM6 RC2 not that it matters now. So you are running a custom recovery right? Try to wipe everything, data, cache, and the dalvik cache. Then flash a different ROM, either stock or any other really to see if that helps.
