AdamOutler Posted August 3, 2015 Report Share Posted August 3, 2015 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.   Quote Link to post Share on other sites

AdamOutler Posted August 4, 2015 Report Share Posted August 4, 2015 Have you tried to insert duplicated sd card into internal slot? Â 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? Quote Link to post Share on other sites

Lucca Posted August 4, 2015 Report Share Posted August 4, 2015 Ok. Â I got the full SDCard image from my AVIC-8100NEX deck. I'm not exactly sure...,but it seems that the S.N. of your original SDCard is 74020007D6 Quote Link to post Share on other sites
AdamOutler Posted August 4, 2015 Report Share Posted August 4, 2015 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?I wanted to save the extra SDCard if possible. The SDCard is expensive (80x SDCard). Â 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. Quote Link to post Share on other sites
AdamOutler Posted August 4, 2015 Report Share Posted August 4, 2015 I'm not exactly sure...,but it seems that the S.N. of your original SDCard is 74020007D6 Ok. Does that need to be accounted for/encoded, on the new image? Quote Link to post Share on other sites

AdamOutler Posted August 4, 2015 Report Share Posted August 4, 2015 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?
