App Error 523 reset - Curve 8320

Hey there. My BB curve is showing the app error 523 reset screen over and over. I cant get it to do much. Every now and then when I do a battery reset it will eventually load the main screen on the phone and say something about exception 3 error...something like that then the app error 523 shows up... but for the most part everytime the phone comes on, within 15 seconds the app error 523 pops up and locks the phone up.
Now I have been reading online for the past day or so trying to troubleshoot the issue, and I've read where I have to load the desktop manager and either d/l the new O/S and/or delete any apps that might have caused the issue. My problem is I cannot get the phone to stay connected to the desktop manager long enough to do anything befor the app error 523 pops up and shuts the phone down again. I have tried taking the memory card out and doing it, also tried taking the sim card out, but that error 523 keeps showing up.
Does anybody else know of anything I can try with this phone? It's really starting to get annoying.
Thanks for any advice..

If your BlackBerry stays powered off with a black screen, follow the instructions below. The only indication of life might be the blinking red LED light in the top corner. Nothing seems to wake it up and Desktop Manager doesn't recognize any device is connected.
1) Make sure you have Blackberry Desktop Manager installed.
http://na.blackberry.com/eng/services/desktop/
2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
"c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
3) The Application Loader Wizard will appear -- click "Next."
4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
Now, See if you uninstall any apps you question that might be cause the error --or theme.
NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.
http://www.blackberryfaq.com/index.php/BlackBerry_Operating_System_Downloads
Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.

App Error 523 Reset

Will somebody please help with my BB Pearl 8110 by walking me through
the complete resolution to this problem?
It all began by turning itself on and off, on and off.
I checked for updates an began the update process to v 5?
Unfortunately it must've turned itself on and off, on and off causing
App Error 523 Reset.
I followed other advice like hard and soft reboots? and my BB began
Blinking 4 times then once repeatedly.
So after going through, what I thought were the correct steps to recover
I've once again returned to
App Error 523 Reset.
At this point all I want is my BlackBerry back. Forget any personal items
I once had. I'll start all over again.
Thanks a bunch for any help and if it helps I will surely post so.
Scott

Hello!
We are so sorry that you are having so many difficulties. While many experience the same (a search here will reveal that fact), there are also many who have very positive experiences with their BB. Not every device is suitable for everyone -- which IMHO is why there are so many choices.
FYI -- these forums are a user-to-user support channel, not a user-to-RIM conduit. As such, it is unfortunate that we all missed your post and did not provide any useful responses to you...but, we are volunteers and not paid RIM support folks...sometime we just miss things. But a perusal through these forums will I think show your experience to be abnormal (as far as helpfulness in these forums is concerned). But, yes, I am biased...I volunteer a lot of time here when I can.
For the benefit of others who search and find this thread, here is the relevant KB for resolving the 523 error:
KB11816 Error "523 app.error.Reset" appears on the BlackBerry smartphone
Good luck!

Re: app error 523 reset... PLEASE HELP!!!!

Hi! Ok, i am totally lost! My blackberry pearl 8100 stoped living as of this morning at 8 a.m. I has a white screen with the same message as yours did, "app error 523 reset" No matter how many times i hit reset, it doesnt RESET! I have been off work since 6 and online looking for solutions. I read what the guy told you about yours, but i dont think i understand. I purchased my bb from someone, and i dont have anything on my desktop manager as some websites say. I do have the usb that came with the phone. Please help me if you can. I cannot afford another cell at this moment and i really like the one i have now. I have also tried the holding down the alt cap del button; NOTHING. I JUST WANT MY PHONE BACK. PLEASE! SOS!

Hi and Welcome to the Forums!
(FYI - we had this split off of a closed thread so that it could receive proper attention...)
First, you need to take the red out of your posts...please.
Second, you need to do the following:
I suggest the following steps (insert plenty of reboots of your PC...not just restarts, but full power down reboots). Also, it is advised that you be logged into the PC on an account with full admin rights. Further, under Vista, use the "Run As Administrator" option for everything. If you have never installed the Desktop Software to your PC, then skip steps 1 and 2.
1) Remove your device OS update package from your PC (add/remove programs)
2) Cleanly uninstall the RIM DTM software:
KB02206 How to perform a clean uninstall of BlackBerry Desktop Software
3) Get a fresh download of the RIM DTM software:
https://www.blackberry.com/Downloads/entry.do?code=A8BAA56554F96369AB93E4F3BB068C22
Choose the version that is newest and (if applicable) compatible with your PIM (if you are synchornizing via USB):
KB12268 Applications supported by BlackBerry Desktop Manager for synchronization
4) Download (to your PC) a fresh copy of your device OS package from your carrier:
http://na.blackberry.com/eng/support/downloads/download_sites.jsp
5) Install DTM to your PC
6) Install (also to your PC), the device OS package
OK...next, follow this KB (including the other links within the KB) for recovery from the 523 error:
KB11816 Error "523 app.error.Reset" appears on the BlackBerry smartphone
Good luck and let us know!

App Error 523 - Reset on 470_b059_multilanguage.exe - BB Desktop SW 4.7

I'm just upgraded to the 470_b059_multilanguage.exe BlackBerry Desktop SW 4.7 and, after step 9, on step 10 waiting for device comes again (can't remember the name of the step) on my device appears the "App Error 523", even after the battery pulled out. Please HELP me.
Solved!
Go to Solution.

installing desktop software does not reinstall software to your device. you shouldnt have even needed to have your device plugged in to install desktop software. you would have to install desktop maanger, plug your device in, install device software to windows, open desktop manager, use either the update option, or application loader option to install the device software to your BB.
and during this installation it went bad. and previous poster was correct... you need to reinstall
close DTM
goto control panel- add/remove progs
check for bbdesktop manager 4.7 and see if there is any other bb program installed... this will be your device software... im hoping its 4.5.x.x
dont uninstall anything here, just for informational purposes, close add/remove progs and control panel
open my computer and go to c:\program files\common files\research in motion\apploader
open the program loader.exe
remove your battery.. and run the wizard, till its complete
you will get a multistage error, close wizard
put battery in and wait till it boots to a 507 error
run loader.exe again

BB 8320 showing APP error 523. How do I back up data before installing new os

Help me pls I'm very desperate> my BB is just over 1 year old. Woke up to find the screen with APP ERRor 523 reset . I've tried all tricks in previous treads without success. Only thing left is to install new os. Trouble is that the BB is not backed up yet. How can I back it up before removing old os and installing a new os

Hi and Welcome to the Forums!
Sorry, but it is highly likely that your data is already lost...so there is nothing to backup now. This simply proves the point that there are two kinds of computing device users...those who have lost data...and those who will. Backups before things go wrong are simply not optional.
Good luck and let us know!

Unique App Error 523 problem

I have a BB 8350i
I installed no new themes or applications and the device was sitting idle and locked. I pressed a button to check the screen and noticed it first told me "Uncaught Exception Index 37 >=37" and then goes to white screen with "App Error 523 / Reset" I tried removing battery, and pressing reset many, many times to no avail.
Now though, when it tries to boot up after reset, I hear my ringtone sound for incoming text message (same ringtone for BB messenger notification, and voicemail) and still goes through the same loop with the uncaught exception and ends ath the app error.
I've tried hooking the device up to my desktop manager but once the device gets into the error messages, my dm software says it can't connect and freezes..
I last performed a backup of my device about 2 weeks ago but I'd still really prefer not to have to wipe out my data.
Unless I'm mistaken, I understand that I can either wipe out the device somehow (don't know how) and start from scratch with my backup file and hope it works, or replace the device if I can.. ? Am I right and what is the best way to fix this?
I tried researching on my own on the internet but couldn't find any other reported problems combining the Index 37 error with the App Error.

Sometimes when you download stuff like themes, apps, even updates to yahoo msgr it causes that error code (someone told me its a corrupted file), I had it happen weeks after the update I did. I think BB App World even caused it for me once. I have about 200 phones and this comes up from time to time, if you get that message you have no choice but to wipe, re-install the software, and then use your backup to reset your info (I've tried avoiding it but you really can't). If you really didn't download anything or update anything then I'm not sure what caused it, I just know how to fix it.
I use JL_Cmder to wipe my devices and then hook the device up to BB desktop mgr and it will tell you that you need an update to your software and will install the newest version of your software for you, then you go back and do a restore.
Make sure your BB desktop mgr is the most current version. I don't know the link to get JL_Cmder, it's all over these forums and on the internet too if you do a search. If you don't like JL_Cmder try BBSAK. BTW, you found a great place for help, I've learned tons from the people here and now everyone at work and of course my friends think I know everything about BB...really I just come on here and do a search.
Happy Berrying!

App Error 200 - Reset, BB curve 8520

Hello,
While I was downloading the new BB software via BB desktop manager, my laptop suddenly closed. After that, when I re-opened my mobile, after reloading, the screen went blank with an "App Error 200 - Reset" in the middle of the screen. I tried pressing the reset button, but it repeats the same system again! How can I solve this problem?! Pleasee Help

Just enter an incorrect one 10 times and the phone will reset itself back to factory settings without a password and then you are good to go. (P.S: note that the device wont lock out it will start fresh as a new device). Have you made a back-up of your BB at any given point in time?
If so, then you can just load the backup through the Desktop Manager.
Please follow the below threads and would give you some more idea on the issue and a feasible solution if mine doesnot satisfy you:
