Ok.  I got the full SDCard image from my AVIC-8100NEX deck.  You can find it here https://builds.casual-dev.com/index.php?dir=random%2FAVIC%2F8100%2F.  I verified the sha256sum after upload.

root@adamoutler-desktop:/var/www/html/sd# sha256sum ./fullsd.img.gz 
e5682db410963d0b57b5eec94f3aa66eb9ae078ffeb1dc3ec4c02c0b7f426da6  ./fullsd.img.gz

This file and the others which are required to enter testmode and obtain this image were included.  Place them on a USB stick, insert into USB1 port to reboot into test mode, then use the write program forcedly>Copy Script option to recreate.

This image came from my deck and is unsanitized.  

I copied it to my other 8100, with testmode_N.key (2), in hopes I could bring it back to life, but I got the "Software Error" screen.

Have you tried to insert duplicated sd card into internal slot?

 

Have you tried this? http://avic411.com/index.php?/topic/80945-upgrading-nex4000-to-nex4100-work-in-progress/?p=333868

Key 1 just sits at software error. Key 2 copies the SDCard. Just to verify, key 2 copies TO internal SD, not from, correct?

I love reading this thread, keep up the good work. Wish I knew just a little of what you guys are saying. Cant wait for the outcome.

I'm not exactly sure...,but it seems that the S.N. of your original SDCard is 74020007D6

I'm totally confused. Can you take a new blank 16gb sd card, record the data on it back using dd command and your fullsd.img file and insert this cart into internal slot of device? Is this method is not working? Or you need to set correct password for this new sd? Device rejecting unknown cards? Why are you trying to use testmode's copy device capability?

The SDCard password is set by the deck according to bass_rock's similar experiment. This renders the SDCard unusable after power on, because we don't know the password.

Ok. Does that need to be accounted for/encoded, on the new image?

According to sources it is possible to change/remove SD card password setting in NOR flash using U-Boot console command:

	"bsp passwd  <passwd> - set sd card password (16bytes)\n"

So all we need is access to console

 

Also it is possible to get password using JTAG or SDCard sniffer/logic analyzer

 

@Lucca is this SN linked to iGo device.nng and/or licenses?

I will be doing that soon.  

Tell me, are there any commands that allow memory read in U-Boot?  U-Boot has the ability to get through many memory protections which it emplaces.  If anything can read the password from inside the device it's U-Boot.   I forget the commands, but I believe it was two letters, then two parameters for offset and length..

yep.. just found it.  http://www.denx.de/wiki/publish/DULG/to-delete/UBootCmdGroupMemory.html 

The command is "md".  Is that in the u-boot sources we are working with?

Adam's device id:

My ids is completely different (UPD: seems like my second id is very close to this two and third id is something like incremental id)

As I mentioned above,each unite has its unique ID,the second strings in your example proove it,so,the last thing I need - those missed connected_services lyc.All the other steps to make Pioneer iGO NextGen works at any android device 2.3 & UP -- not a problem...

hello guys
greats from brazil

i used testmode to replace some IGO files 
here in brazil we have new maps from nokia here (2015 Q1) for old IGO devices
i've put then inside the HU, but didn't work. I believe maps licenses are individual (each map have your own license)

now, i've extracted IGO folder and apk and will try to use it in anothers android plataform (as cellphones and tablet)

and investigate things about new igo licenses

 

Pois new files working well
Speedcam files works too

only new maps doesn't work (fpa e pbl archives)

i wil disseminate it in Brazilian gps forum to work together and solve things

any news will be posted here

thanks and sorry for my bad english

 

@Lucca is it possible to patch system libraries (there is calls from igo to system in disassembled sources to get hardware ids) to change licenses? Or you know easier method?

 

Not needed to change licenses...,it's a bit another "technology"

New maps doesn't work,because the latest *.lyc for Brazil content is (Pioneer_Primo_Brazil_14Q1_HM_ExtPOI_3D_DEM_HNR_TTS_JV_CAR_NF_) .

Unfortunately my friend,those licenses are useless for iGO NextGen.
