Help please: reboot loops following USB port repair
 

Hello everyone

I am having some issues with my n900 and I need your help, around a week ago my n900 usb port got broken and it came off the device, I took it to a friend who fixes cellphones and he resoldered the usb back again, its the second time he fixes it for me, the first time there were no issues, so when he put it back together and turned it on a reboot loop started and it kept going for a couple minutes then it finaly turned on, for a couple hours it was working just fine but then out of a sudden it rebooted again and started with the reboot loop again, this has been happening since then, i did some research around and it apears that flashing sometimes helps, so i flashed the device, vanilla first and combined latter as it says on the wiki, it worked just for a couple hours and then it rebooted again, the only diference is that now it doesnt loops most of the times, these reboots happen at all times no matter what i am doing with the device, some times it also happens when its charging, i havent seen it reboot when its on stand by.
I am takeing it back to my friend to check if theres anything wrong with the hardware.

Can you please help me to find out what is the reason for these reboots?

I installed HealthCheck and it shows:
Boot Reason:
sw_rst

Please help, I really like my n900 and dont want to change it for an other cellphone.

Thanks.

Re: Help please
 

if you haven't installed rootsh yet, do so
once you have done it, open a X Terminal, type
if it doesn't show anything conclusive wait until it crashed and try again

if you have a µSD card, put it in the N900 (next to the camera lens area) and do
and attach dmesg.txt it to a post here

Thank you for your fast response

Here it is

eeeh, silly me :eek: ~:c)
dmesg only shows the messages since the last boot, thus won't show what caused the last crash / stop :confused:
instead

and let it run 'til a crash
and attach kmsg.txt to a post here after the crash

Re: Help please: reboot loops following USB port repair
 

Done, just waiting for that reboot
Thanks

Sorry i think i had it but aparently I am doing something wrong
I typed

root
cat /proc/kmesg >/media/mmc1/kmsg.txt &

but its giving me:

Nokia-N900:~# cat: can't open '/proc/kmesg': No such file or directory

It did created a kmesg.txt file but once the device rebooted and I tried to open it it was empty

took a while here too, sorry 'bout that :p

good news is there doesn't seem to be anything wrong with your HW.

bad news is, ain't exactly a HW engineer :confused:
i merely compared your file with what happens on my N900 when i slide kbd, switch from 3G to WLAN aso.
all looks perfectly normal to me :o

i know it is frustrating if you don't have another N900 possibly even another mobile phone, but could you try & made a STOCK standard install (still with your personal data, of course, but WITHOUT any extras-testing, leave alone extras-dev SWs...) :(
even better, not even extras stuff :mad:

my way of saying that it could be SW
also hinted at maybe by the fact that if the device is idle, it doesn't crash.
i assume that even when idle, you have 2G/3G or even WLAN on, right?
slide HW kbd to check if you are still online aso?
