curve 7 always rebooting

my BB curve 7 which is barely 2 months old from the date of purchased is always rebooting. The phone was showing 'JVM error 545' just a month after purchase from an authorised dealer and was taken back for repair. Since after the phone was swapped, it has been rebooting at least 5 times daily. what may be the cause of the problem and possible solution.

Re: curve 7 always rebooting

Hi and Welcome to the Community!

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.

You may also need the use of these tricks:

Good luck and let us know!

Re: curve 7 always rebooting

i have tried all the suggested methods but the problem still exists. please note the the rebooting started immediately the phone was swapped after it experienced the "JVM error 545". the phone reboots even in an idle state. attempts to downgrade the OS always shows that there is no software available for downgrade for the phone.

OK...that means that you are using the "automatic" methods, which sometimes fail. So, you need to override and take control. With a PC (not MAC), you do that via this process:

1) Uninstall, from your PC, any BB OS packages

2) Make sure you have the BB Desktop Software already installed

3) Download and install, to your PC, the BB OS package you desire:

4) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:

  • C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
  • C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML

5) Launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC. If, during the process, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.

Or, instead of step 5, you may need to use now one of those prior "tricks" provided above, but with the installed (to the PC) configuration rather than other means that might be suggested (e.g., the Update website).

 

Good luck and let us know!

Re: curve 7 always rebooting

i followed the steps and installed a new OS. it is still rebooting but the frequency of the rebooting has reduced. it has rebooted like thrice in the last 12 hours. before the installation of the OS, it will reboot like every 20 minutes. how do i completely eliminate this problem?

Re: curve 7 always rebooting


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.


 

Good luck and let us know!
