Hi all,

My TX has decided to go into a perpetual reset loop. All I see is the orange Palm logo with a black progress indicator on the bottom, then the grey "palm powered" screen, then screen goes blank for a second or two, and then it all starts over again. I tried hard resetting it but it did not respond.

To my recollection, this was not preceded by installation of any new software or any other unusual event.

What to do? (Right now I'm looking at the pretty logos and waiting for the battery to die, but I don't know whether that will finally return the handheld to a working state.)

Thanks for all and any suggestions,

let battery die, and then wait a day or two. then charge it for a few hourts. should come back. if not, have it replaced.


it is a bug in the system that makes it possibly for NVFS to errorneously write to the system area of flash, making the system image invalid and unbootable.

Actually the thing to do (in my experience) is to reset and hold 'up' on the d-pad. Let this go when you get to the grey Palm logo. This should stop it from loading whatever it causing your TX to do that.

If this doesn't fix it do a zero-out reset and let Hotsync put everything back.

Fixed it for me after I installed a few apps that didn't play nice even though they were supposed to...

This being done the same way as the zero-out reset on the T5?

Thanks,

I know you once talked of setting system area to read only in the MMU. Have you thought any more about a utility to do that?

Thanks, Dmitry. Will try this.

I guess I got lucky then. Mine had the same situation go on where soft resets didn't fix it, nor did letting the battery drain.

Doing the zero-out and then letting the standard palm backup reinstall everything put it back just fine... along with deleteing the software I ran right before it happened. Installing the program didn't hurt it at all - running it caused the reset and loop.

Thanks for the info. I'll know if it happens again.

Hi!!

I had the same problem, as I posted in this forum, and after trying all kind of resets, and having the battery down for many days, I finally sent it to Palm to get it replaced.


Bye.

Just to let everyone know:

I let the battery drain for a few days and then powered up the TX but it kept going through the loop. I then tried a hard reset (the one where you need all your friends to push the buttons), with no success. So I sent it back to Amazon for an exchange. The new one is behaving so far (about a week).

Thanks for everyone's ideas. You guys are great.

The problem is probably a corrupted Saved or Unsaved Prefs DB file. If you do a warm reset as instructed above, and then (or move) these files, your problem should go away. However, all of your preferences will also be deleted.

My TX got stuck in a reset loop as well. None of the different types of resets had any effect on the unit. I even disconnected the battery for several hours to no avail. Had to have Palm replace it. I believe that dmitrygr has the right idea. Let the battery drain and see if that helps. Best of luck.

no good. nand is non memory-mapped [WHY OH WHY??]

Lemme get this straight; there's a bug in the NVFS system that can brick the TX? Does anyone know what conditions trigger it? Does Palm know about it? GEEEEEZ - PALM GET YOUR HEAD OUT OF YOUR ***!!!

dmitrygr

very low stack in Arm native apps/PACE when a Dm* call happens is one of them



Do they know? I'm sure they do.
Do they care? Now THAT is another story.
It is not common enough for them to care really

How about patching the NVFS code to prevent writing to that area? Or do we not know enough about the NVFS code to do it.

By the way, how does NVFS work? I assume the Dm*() functions get redirected to access dmcache as well as to functions that access the hidden volume. Are the functions that access the hidden volume just the standard VFS*() functions (maybe with some global flag set to enable access to the directory where all the stuff is stored)?
