3.1.0 public beta crash after install

TheMaxxGnL · Aug 8th 2015

I just today received my KPA/remote bundle. When I fired it up the remote prompted me to update the KPA firmware. When I logged on to the site I saw the 3.1.0 public beta and decided to be optimistic. The f/w seems to have installed correctly but upon reboot it crashes when loading performance data. The error message reads:

expr=sqlite3_step( mGetSlotids ) == SQLITE_ROW
file=./src/profmodes.cpp
line=3270
func=void Profiler::ProfilerModes::RetrieceTracksIDs(Profiler::ExtractedPerformanceData&)
swvs="Release: 3.1.0.11311" (CRC-44CDA158)

Is there a way I can force the machine to factory reset? I tried holding down the System button while powering up but it still tried to load the 3.1.0 firmware.

I've done nothing to the KPA except browse a couple of presets. Any advice?

Hi, I just updated my KPA - same problem.
Help!

Yeah, same error here. Moved back to 3.0.2.

How did you move back?

hi
just put 3.02 in the root of your stick and you can go back to 3.02

digbob · Aug 8th 2015

i think to use 3.1
install 3.02 and wait till all is working ink remote with 3.02
then try to update to 3.1 the usual way
copy chaos bin to the update folder
and then let the update run till all looks like its working, ink remote

Yeah, I've tried these things already. I've got the 3.02 kaos.bin in the root of the Kemper-formatted USB stick. The stick is mounted in the KPA and when I power on the KPA it just loads the installed 3.1.0 f/w and crashes. No opportunity to revert to the older version. Is there any key sequence to hold down when starting that will give me a factory reset or force a check of the USB stick?

Put the 3.02 in the root, not in the OS update, or any other folder. then when you power up the kemper push in both of the PAGE buttons simultaneous. should start the downgradeing to that firmware.

I just did this and then tried to update back to 3.1 but with no luck. still get that error message. gonna have to downgrade again and wait until kemper comes with a fix or a solution specified to this.

Anyone tried putting 3.1 to root and then push the PAGE buttons? would that be forcing the update? don't dare to try personally

You rock, Rownie. I've successfully up/downgraded to 3.02 and the remote is communicating. I don't have time for further messing with it, and I may wait for 3.1.0 beta 2 before taking another shot at it.

Same error.

Just out of curiosity, how is it that the same update can brick some units but not all?

I'm fairly illiterate when it comes to computers, and the update worked fine for me. However, figuring out how to upgrade to 3.0.2 after first buying my KPA was a bit of a struggle until I figured out how to do it.

paults · Aug 8th 2015

What versions of the operating system are you all updating from?

Lokasenna · Aug 8th 2015

3.0.2 here.

Frodebro · Aug 8th 2015

Upgraded from 3.0.2

please open a support ticket and send a backup with it, so it can be investigated.

Rownie · Aug 8th 2015

I've got a feeling its related to the profiles or the performnce rig, I think removing all the performace rigs and added profiles or reset it back to factory and re update everything would solve it.

A factory reset solved my problem with crashes.

Any advice?

We identified the bug and will provide a fixed version shortly. In the meantime, you can restore 3.0.2 by putting the 3.0.2 operating system on an USB stick and hold the PAGE buttons whilst powering on. this will re install 3.0.2.
