BB 8100 keep restarting itself

I have a problem with my 8100;it restarting itself after reinstall OS

I was forced to reinstall OS because of this problem,but nothing solved

First i tried to reinstall the 4.5.0.55but after the reinstall,a box wich say" verifying security software" appear and i think that everything is just fine,but when the initial setup appear(a box containing 3 choices:run setup wizard,remind me later,dont ask me again) i wasn't able to scroll up or down.If i try to click the trackball or enter key nothing happen.Afer aprox 1 min the phone restart itself.

After that,i've read somewhere that is need to downgrade your OS and i've downgraded to the 4.2.1

Now i'm able to scroll up or down in intial setup box,but the enter or trackball event isn't assigned and the phone keep restarting.

The install procedure was this:

install desired device software on PC

delete vendor.xml

running loader.exe and conecting the device without battery so that the pin number appear in the box(pin:xxxxxxxxxxx or somethime pin:unknown)

after that plugging in the battery and load the instalation and wait until finish

 in one case i tried with commnad line (loader /nojvm) option  but the same story

 

in the past when i've upgraded my device os,i had similary problems(than i failed the upgrade and i was forced to reinstall the os like now ,but despite now ,with succes)

This problem appear from nothing,my phone was working,sitting on my desk and when i want to see what time is,i realized that the phone was turnned off and i wah thinking that the battery is discharged,but when i realized that the phone is restarting...........

The ideea is that my phone was working and after 1 min was crashed without my interaction 

Sorry my english

Hope that somebody have the"cure"

Re: BB 8100 keep restarting itself

Greetings, and welcome to the BlackBerry.com Support Forums.

 

The method upgrading the device you described is the best to use. It should work.

 

You might have some third party applications or a theme on the device which is not compatible with OS 4.5, which could be causing the restarts.

 

I would recommend a complete wipe of the device.

You will need to use JL_Cmder to wipe the device and subsequently load the OS to the device. Follow the instructions here:

Re: BB 8100 keep restarting itself

i tried the method described in the link but the same symtoms

I wiped the phone(i must say that when i wiped the phone the battery was plugged in(without battery i can't connect to the handheld and succesfuly wipe))

After i got the 507 error,i opened desktop manager and install the software 4.2.

but in the end the result was the same

 

I gues that is some hard problems(some internal conectivity issues on mainboard)

Once time ,i charged the phone with other charger than bb charger(the pins format was the same) but was working after that

 

Thanks anyway

Re: BB 8100 keep restarting itself

ok, I didn't know you had done all that and that it had not worked out for you.

 

That's the only suggestion I can make.
