if Appratio boot in CE, and reboot after without SD - you HAVENT cis.exe or ither files at \"NAND FLASH\CE66" forlder.

i has this before when delete my cis.exe.

you need try update again or copy files by hand.

@Xradeon, thanks for the file. It is not working.

@carver: you post on the beginning some windows folder files contents for instance a file named "c66shell" what I understand thta this file is the main application of the radio system. My question is: Should I put this file or those files on the nand memory?

Guys,

The problem is solved! The updated files were be sent corrupted by the microSD card. Only today I realized that the card could be a problem. I bought a new one and sent the all firmware files including the 2 ones sent by Xradeon.

I would like to say Thank you guys for the help and support.

Cheers!

no need put c66shell to nand disk. it files only windows switcher to testmode or main shell.

it already present in windows folder, but you cant see it.

main shell - CIS.EXE, from nand.

Guys -

Really on to something here. Have had my AppRadio since July in my Evo X. A few weeks ago, it started spuriously rebooting. It progressively got worse. Instead of only working for the first power on after sitting for a period of 12 hours, it wouldn't work at all. Called Pioneer. They wanted me to tear it out and ship it back for replacement. I decided to do some checking on the web to see if anyone was having the same problem. Brought me to your thread. I tried to re-flash the 2.22 update. It wouldn't load the flash. Just sat there at a blank screen (but it wasn't rebooting every 5 seconds like normal). So I downloaded the CE66Tool and put the contents of the 2.22 update on the SD card. It booted into CE and I was able to run the update EXE from the SD card. It updated the NAND 100% and rebooted. When it rebooted it came up just fine and asked me for my Language settings. Once selected, it booted into CIS no problem. I will test it out over the next few days, but I think interrupting the normal boot process long enough to run the flasher did the trick. I'm guessing the NAND developed a blad block after the update. When I pushed the update again, it likely failed to write to said bad block and moved to the next one. But I'm not certain.

Anyways, thanks carver.

its work to appradio 2 SPH DA100 ?

Will this work on the AppRadio 2 (SPH-DA100)?

Guess that's a no!!

In the middle of a long night of hacking my AppRadio (SPH-DA02), I nearly bricked it. My friend and I had disassembled the firmware and were attempting to get rid of those godawful caution messages. An ill-conceived jump opcode wrecked all of the deck's app functionality and sadly, the firmware upgrade mechanism so we couldn't restore the old firmware. 

We came across this thread but were unable to get the CE66Tool to work (possibly because of said earlier hacking). After a bit of hair pulling we hatched up a workaround that I thought was worth sharing here.

Another way to boot into Windows Explorer:

If you take a copy of CIS.exe (I just used the one from the 4.17 firmware), rename it to "CE66Tool.exe" and put it in the root of the microSD card (with nothing else on the card), and reset the device, it will crash into Windows Explorer. You can then force CIS.exe (the local copy on the deck) to quit and then you are free to do anything in Windows you want without being bothered by Pioneer's interface. You can even replace the copy of CIS.exe on the deck with the one on the card (after renaming of course) thereby recovering your borked deck.

The reason this works is because there is a bit of code very early on in CIS.exe that checks for multiple instances of CIS.exe running at once. By causing a second copy CIS.exe to run from the microSD card at boot, you get an error and access to Windows - even though your second copy has been renamed to CE66Tools.exe.

You can also connect a full size USB keyboard to the iPod USB cable on the deck. This makes navigating Windows on the deck a lot easier - it also helps you force CIS.exe to quit a bit easier! I didn't see this mentioned earlier so I thought I'd point it out.

If anyone has had any luck getting rid of those miserable caution messages (both the one at startup, and the one when running an app the deck doesn't like when the brake isn't on), I would love a patched copy!

Happy hacking!

can someone figure out how to do this on the da100?

any luck for the da100 mine is bricked in the boot loop after friend tried the upgrade incorrectly
