Glauco Posted July 17, 2017 Report Share Posted July 17, 2017 If you find an image for your device, F77 or something, it will be about 8GB or 16GB, write it to an SD Card and replace the SD card in your device Can not you use the same sd card? Quote Link to post Share on other sites
Magister Posted July 17, 2017 Report Share Posted July 17, 2017 Can not you use the same sd card? yes of course Quote Link to post Share on other sites
Glauco Posted July 17, 2017 Report Share Posted July 17, 2017 yes of course So I have to download the image on the pc then go to a USB and then put it in the usb2 port and I can copy it to the sd card of the device? Quote Link to post Share on other sites
Magister Posted July 17, 2017 Report Share Posted July 17, 2017 If you cannot access the "test menu" because you overwrote something (like the kernel) in your unit and the displayed message comes from the bootloader, then you have to put the SD card in your PC and copy the raw image from your PC on the SD card. You have to open your unit to extract the SD card from it. Quote Link to post Share on other sites

Magister Posted July 17, 2017 Report Share Posted July 17, 2017 By putting the SD card in my pc, it gives no signal. There is no driver for the SD card. Can not shake the SD card? No because it is password protected, take a new one Quote Link to post Share on other sites
Glauco Posted July 17, 2017 Report Share Posted July 17, 2017 No because it is password protected, take a new one So in that case will not I be able to unlock? Quote Link to post Share on other sites
Glauco Posted July 18, 2017 Report Share Posted July 18, 2017 FAQs What does this mean? 1. WARP can be disabled 2. Internal SD Password Lock can be removed (Requires a new sd card afterward) 3. Debug can be enabled. 4. We can modify the Internal SD Card by inserting it into the computer with the above turned on. 5. Custom ROM development can truly begin. What the heck is warp? A: It's the hibernate function.  At the factory, they hibernate the device and every time it turns on it uses this information. This prevents us from loading custom firmware because the deck chooses this memory loaded information over the filesystem changes that we create. What is the BSP? A: The BSP is a special are in the NOR Memory (different from the SD Card), where U-Boot, EasyRecovery and all the low-level U-Boot settings are located. It is 84 bytes in size and has two copies in case one fails. What is NOR Memory? A: The NOR Memory is an area separate of the SD Card that contains, boot settings, recovery partitions and the boot loader. Why do we need to remove the SD Card Password? A: The Pioneer dev's decided to put a hardcoded password lock onto the Internal System SD Card that prevents you from just putting it into your computer. By removing it we allow the ability to remove the internal SD and to put it into any computer to modify the Platform files, without having to run an Update. What is the SD Card password? A: LKPFeD4BcVzESR2Y Can't we just unlock the password on a computer and not change the BSP? A: Yes, and no. In order to unlock the SD card you need to have the ability to run CMD42 on the SDCard which most linux distributions and os’s do not have. What is Debug mode? A: The Debug mode outputs more logs and turns on a console port somewhere on the device. We still do not know where that is. NOTE: It is most likely possible to patch the kernel to use the iDataLink port as a UART console for ADB. What are the device paths if I want to change the backup or restore locations? A: /mnt/udisk/ for USB1 /mnt/udisk1/ for USB2 /sdcard/ for external sdcard What is the Partition Map look like? A: For a 8GB internal SD Card (AVIC 5000) it looks like this: Disk /dev/mmcblk1: 8069MB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system MY Findings: 1 538MB 548MB 10.5MB primary android boot A BOOT/BOT.PRG 2 548MB 559MB 10.5MB primary android boot B 3 559MB 1830MB 1271MB extended 5 559MB 590MB 31.5MB logical android recovery A RECOVERY/REC.PRG 6 590MB 622MB 31.5MB logical android recovery B RECOVERYEASY/ERY.PRG ? 7 622MB 1159MB 537MB logical ext4 /system PLATFORM/PLT.PRG 8 1159MB 1293MB 134MB logical ext4 /cache 9 1293MB 1830MB 537MB logical ext4 /data USERDATA/DAT.PRG 4 1830MB 7702MB 5872MB primary ext4 /extdata How can I unlock my SD Card? A: Follow the following steps: 1. Set SDCard password in BSP 2. Place Test Key N3 on USB stick 3. Power on unit 4. When screen goes black turn unit off and back on 5. When unit shows Mode Change OK screen, remove the SDCard and power off the unit. Update 8/16/2015: Added how to unlock an SD Card. Could you give me more information on how to unlock the sd card of the avic device by computer? What system / program can I perform this unlock? Quote Link to post Share on other sites
Magister Posted July 18, 2017 Report Share Posted July 18, 2017 A lot of this info comes from https://fail0verflow.com/blog/2014/enhancing-the-avic-5000nex/ (there's a part 2 too). I never unlocked my SD card, the procedure is there but somewhat cryptic I agree... Put the password in the BSP, boot the unit with a USB with the N3 key, someone who know better could put better step by step explanations. Quote Link to post Share on other sites
Glauco Posted July 18, 2017 Report Share Posted July 18, 2017 In this sait only speaks as it does via JTAG. I want to see if anyone can unlock via any operating system.

borconi Posted July 19, 2017 Report Share Posted July 19, 2017 Hi guys. Nice work, not a Pioneer owner myself so I cannot test/try/brake/etc I have scanned through the topic but I couldn't see an exact answer. Can you install any app on the units now? If yes can you also remove any of the factory apps like (Android Auto)? I'm curious to find out if the factory provide Android Auto app can be replaced with my version ( http://forum.xda-developers.com/general/paid-software/android-4-1-headunit-reloaded-android-t3432348 ) which potentially could give a few benefits over the standard version: 1) It supports unlimited browsing 2) It allows you to connect to AA over Wifi as well. If anybody is interested in trying it out give me a shout on borconie@gmail.com and I can send you a copy of the apk for trial purpose. Quote Link to post Share on other sites
