Re: 9900 restarting again and again

I've a same problem. I was using v7.1 on bold 9900, suddenly after a year it has a problem with restarting again and again. Now i can't use my phone for anything because it keeps on doing this. When its plugged in with usb with my laptop it comes back alive. So I backed it up, downgraded to v7.0 and again keeps on re starting. So upgrading and downgrading doesn't help. Please tell me what to do now.

Hi and Welcome to the Community!

You may also want to investigate the use of BBSAK (bbsak.org) to perform the wipe it is capable of.

You may also want to try the "Bare Bones OS Reload Procedure" to attempt to narrow down the precise causal item:

  1. Load your OS "bare bones"...if anything is optional, do not install it.
  2. If the behavior presents immediately, then try a different OS with step 1
  3. If the behavior does not immediately present, then run for as long as it takes for you to be sure that the behavior will not present.
  4. Add one thing -- no matter how tempting, just one.
  5. If the behavior does not present immediately, then again run for long enough to be sure it will not have the same problem
  6. Repeat steps 4 and 5 until all things are loaded or the behavior presents

When the behavior presents, you know the culprit...the last thing you loaded.

If the behavior does not re-present, then you know that either step 1 or 2 cured it.

If the behavior presents no matter what, then you likely have a hardware level issue for which no amount of OS or software can cure.

You may also need the use of these tricks:


Good luck and let us know!
