Hey Folks , I've been using 9790 for around 4 months and it was working well... Suddenly today i came up that it was just not responding to any action i perform. Its not responding and all over just black screen. I tried to plug with wall charger but still no action... Nothing is happening nor the device is starting.., need help with it.... Note : ive checked my JM1 battery and its fine but i dont know if the problem is with decive hardware or software... Any help i tried that kick start process too and still after 4hours no action.... Any other suggestion is welcomed :smileyhappy:

Re: Blackberry 9790 Not Starting Up....

Hi and Welcome to the Community!


Normally, the "kick start" attempt is only half of what is offered...usually, there also is a sequence to test your battery as the causal item...have you done that?



Otherwise I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.

If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.

But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.
