I had MBR error, i used another card reader and it worked
[Android Head-Units] kalinkamaen:
Yes, I am getting the same error on 3 different computers. I am using Sdmicro to SD adapter, and I think this is the problem. I need to get a usb to micro SD.

No issue at all on all usb stick on all computers.
[Android Head-Units] 9932ymx:
you have to try with a micro sd 4go format (fat32) 2 times after taking sdboot. can be an accounting problem with firmware me I have a 7.1.1 firmware if it can help someone

i use 16GB emtec micro SD with and SD adapter.

on my DELL E5440 laptop it give me MBR error.

on my 8 year old acer it work ....
[Android Head-Units] 9932ymx:
me it works with a USB key too .. try to change the firmware
[Android Head-Units] kalinkamaen:
Firmware did not help.

After using this tool, bot my SD cards is showing 3.86 mega byte in windows. 1 is 16 gb and the other is 64 gb. How can I get it back?
[Android Head-Units] 9932ymx:
Format (fat 32)
[Android Head-Units] kalinkamaen:
Had to format it with my phone, windows didnt work. Phone identified it as corrupted.

I am trying on a Windows 7 pc 32 bit. And SDboot software sees my sd cards as 0.0 GB. Even if woindows shows 16 gb. It must be som write protection on my adapter?

---------- Post added at 11:58 AM ---------- Previous post was at 11:36 AM ----------

Man I tried everything to get it to make a bootable sdcard. On windows 10 firmware tool recognize sd card, but not in windows 7 32 bit.

Windows 10 i get MBR write error, Windows 7 error on formating. I do not have a windows XP.

I hav now tried with adapter and with sd card in phone. Failed with 2 different sd cards.
[Android Head-Units] 9932ymx:
I'm looking tonight to make a sdboot micro sdboot I'll let you know
[Android Head-Units] kalinkamaen:
Ok, perfect, I have sent a mail to shop i bought my unit. And asked for tools, firmware and guide. Crossing my fingers. But I do not have any high hopes.

I could see there is a new firmware out. created yesterday.

hxxps://drive.google.com/open?id=1BgvReQ0y3ZFF5XXf_-89L7Py0t6K8Fx6
[Android Head-Units] InZone01:
Thanks, it is for 7.1 right?
[Android Head-Units] kalinkamaen:
Yes this is 7.1 only.

I have managed to make bootable SD. The problem was not SD cards at all, but deffault windows driver. I updated the SD card reader drivers from original site. And now it writes firmware on sd card with no issue. But trying to flash on boot, was not possible. The screen went directly to no signal. Nothing happened. So I think we are missing something, a file etc?

Here is another thing. If you want to try out different img files. I think you need to change it in the loader batch file. And write the file you want to use?

del SDBoot.bin /F
copy [COLOR="Red"]SDBoot_V2.19.bin[/COLOR] SDBoot.bin
SD_Firmware_Tool.exe
del SDBoot.bin /F

[Android Head-Units] InZone01:
Updated today. XCDVR app doesn’t work, writes that SD card isn’t inserted. IPTV app can’t open streams. Othewise everything is working fine including Google Play Services.
[Android Head-Units] 9932ymx:
the sound works well with the new firmware
[Android Head-Units] kalinkamaen:
Sound seems the same as last FW. Only change I have seen is brightness controll, but I am unsure if this was also on the old FW.
[Android Head-Units] 9932ymx:
is there a firmware 7.1.1 rooter ????
[Android Head-Units] 9932ymx:
I received a message from the Chinese seller who told me to repair the sound must connect a son to the chassis da unit and connect to the chassis car (to try)
[Android Head-Units] kalinkamaen:
You mean ground to metal chassis on unit and from unit to car chassis. My unit has an ground to chassis. Could be that they have fixed mine then. Did he give you any metod to sd boot to recover your unit.

I downloaded jpg file, but i cant get open. Thats a first time for me. Are you sure that you shared it with key. If not its encrypted
[Android Head-Units] teletype:
Yes, I have Debian 8 bootable from an SD card. Currently it's only working with the serial console I added. I've been having trouble with drivers, and haven't been able to get framebuffer, wireless networking or access to the internal flash working yet. So, not very useful. I haven't been able to track down the actual manufacturer of the SOM board in these units. They appear to be called "ZXW", if they release kernel source it would be super helpful but I have found nothing.

I am going to try working with the stock kernel a bit and see if I can use that to build some sort of useful recovery SD, which is my actual goal here. So far I've been pretty obsessed with getting an open source kernel going since that opens a lot more doors.

TL;DR: If you just want to edit system files then the method I detailed in post 400 should work. It just doesn't give you Magisk or anything to access root outside of adb.

Are you sure that we do not need to download mode for SDboot to start? If we can get our unit in to download mode, its possible to flash it with rockchip batch tool.

Here is a rockchip SDboot guide, and they put it in download mode:

[Android Head-Units] psy460:
Yes but we have any way to put it in download mode. :confused:
[Android Head-Units] kalinkamaen:
No, but I have seen a rst solderpoint on our unit. So it is possible to solder a switch for this easy. But I am not sure to where. RST to ground or RST to 3.3 volt.

I will take a picture of this on the board.

[Android Head-Units] kalinkamaen:
With sd card mounted? Thats not good.

with and without SD card.

the only good point is that device try to boot from SD card.
[Android Head-Units] kalinkamaen:
Yes I agree, It seems like its booting from SD, but cant find the correct file, bescause it get stuck. Coukd it be the wrong name compared to what its looking for? I tried to change name on img to PX3, but it did not help.

---------- Post added at 04:31 PM ---------- Previous post was at 04:02 PM ----------

psy460 i have a new suggestion for you!!! You have to try this.

Delete or get rid of your old flash sd tool and download this one: https://mega.nz/#!XQ02hSyK!1uYXo1VEsu_lEY2LxUKrZABA1Wjrw2nQqMydhBVlxI4

Unpack it and and move the folder flash folder to C:

Open: SD_Firmware_Tool as administrator

un check on third option: Upgrade Firmware And check ONLY SD Boot.

Load firmware and push create. It is now makeing a unusable sd for Windows, Go and try it. Please report back asap.

It will take 1-2 minutes to finish. In the end it will look like image below. And you will no longer find you sdcard in windows. To restore SD card, use restore button in tool.

This is what windows says trying to open SD afterwards:
[Android Head-Units] psy460:
will try tomorow :)

My first try also went to error. Changed usb pen that helped.
[Android Head-Units] teletype:
Definitely not. I have a custom built Linux kernel and a Debian install on an SD that boots fine. If you have an SD that's not booting, if you can dd an image of it I can try it on my modded unit and see what the console output looks like. In general if you have an SD that should be bootable but get a "No signal" error, the bootloader is being recognized and it's running into some other problem.
[Android Head-Units] kalinkamaen:
Hello Teletype.

Thank you for your info. If you want to try to make a bootable sd with stock firmware and test, please do.

You need to download this windows software.

https://mega.nz/#!XQ02hSyK!1uYXo1VEsu_lEY2LxUKrZABA1Wjrw2nQqMydhBVlxI4

Extract it. I ussaly move the extracted folder to C:, because on som win 10 computers i get config error when trying to open it.

download firmware from here:

https://drive.google.com/drive/folders/1iVDOXHbqL10G0An5l_b0SYl285RLrom8

Open config file

Change language to english like this:

Save as allfiles and not as text file.

Open as administrator "SD_Firmware_Tool.exe"

unhook upgrade firmware

hook sdboot

load firmware

and push create button.

U need to have a SD card mounted. It wil be formated by program.

Try another usb pen.

try both usb ports.

remoive all other connected usb harware.

format your usb pen to fat32

[Android Head-Units] splashboy:
Hi guys.

I have this screen also in my e90. Before i had the gen1 with 1g, updated to gen2 2g because i had some problems.

With this headunit i got 2 problems.

1: youtube app in full screen has a big black line at the bottom, 1gen didnt had this problem. Tried older firmwares but doesnt change anything, seems to be a problem with the software of the screen.

2: bluetooth music streaming with an iphone is really bad, the sound has much static in it, with my samsung i didnt had this problem. In the ram settings i changed bt module to “feiyitong”, this makes the sound quality 10 times better with no static. But the problem is that it disconnects bluetooth after 20sec.

I hope we can fix this problem, all the rest works perfect.
[Android Head-Units] psy460:
just tried SD BOOT, device do not boot on SD card. just boot loop.

now i'm trying to do firmaware update, using v1.46 instead of 1.43 and the 2.12 bin which came with 1.46
[Android Head-Units] kalinkamaen:
Dammit, sorry to hear.

You need to restore sd card again. If you get MBR error, I fixed it with format SD inside phone.
[Android Head-Units] psy460:
I tried 2.19 and 2.12 SDBoot with the 1.46 programm with firmware upgrade ticked, but it boot on device.

so i think we have to use 1.43.
[Android Head-Units] aclearersky:
So with that sd card tool I had to use 4 different SD cards before one would work. They all gave me some sort of error. And I thought it wasn't working as well but my screen showed no signal but if i touch the screen or I drive buttons it comes up. It still displays no signal every time I start my car

Oki , did som soldering today to see what this rst solder pad was. Check images under here.

I soldered 2 wires, 1 on RST pad and 1 on ground pad.

And soldered a switch on the other end.

I tested to power it and turn on switch, and I now can confirm that this is the same switch we have installed in front or back on our units.

But on this first picture, can some one tell me what these 2 pads named CLK and DIO stands for or used for?
[Android Head-Units] 9932ymx:
I'm going to take apart a touch pad to see

---------- Post added at 07:26 PM ---------- Previous post was at 06:43 PM ----------

2 touch pads disassembled but no informatio
[Android Head-Units] kalinkamaen:
CLK I think has to do with SD card. Clock serial as I have read.

http://www.xess.com/blog/accessing-the-xula2-microsd-card/

But I do not have a clue what it does. I doubt it will help us to boot in recovery mode.
[Android Head-Units] teletype:
Pretty sure that is an SWD port. Haven't messed with it yet but it's probably quite useful.

I've been working on getting a recovery method going that doesn't require disassembling or modifying the device. I'm getting close, and have TWRP booting off an SD card. I'm trying to work out how to set the video mode correctly. Currently the display is severely distorted, but touch screen does work.
[Android Head-Units] kalinkamaen:
Wow, you are the man Teletype, thanks for sharing. I wish I could help out, but this is way out of my skills.

What do you think we can use this Serial Wire Debug for?
[Android Head-Units] teletype:
It depends on the implementation but it should allow a lot of access to the device. There should be JTAG access to read/write the flash directly, debugger access, etc.

Getting closer... Still not working from SD boot, but it looks like my TWRP kernel/ramdisk is good. I guess the bootloader initializes the display and sets the video modes. I got a bit ballsy and flashed TWRP over my stock recovery partition (as root using ADB over tcp) and then ran adb reboot recovery. Don't know how much further I'll get today as Gin and Tonic will probably be a factor later in the afternoon. :D
[Android Head-Units] kalinkamaen:
Wow, you got some balls there. Be carfull to not brick it when trying. TWRP is a good step forward, but if we can`t boot in to it without android software installed. It is not helping against bricked units?
[Android Head-Units] teletype:
That's why I'm working on a bootable SD version. These units will boot off SD instead of internal MMC if the SD is built correctly. I spent a couple weeks trying to get a custom kernel going, and did make an SD card that will boot Debian without going into Android at all. I ran into a lot of trouble getting drivers working so it wasn't very useful. Currently working with the stock kernel just to get something running. What I have now would be enough to unbrick for someone with a fair amount of Linux experience, I think. I don't think I'm too far off from a fully functional TWRP SD though.
[Android Head-Units] CleanKM:
Do you mind listing what you think might have caused this boot loop issue so that i don't find myself in the same spot? Was it changing it to ART?
[Android Head-Units] jeffc83:
For once, I am 100% without a doubt POSITIVE that switching to ART caused it. I am now understanding why they LOCKED the dev settings out! (for people like me that "try" things they shouldn't) Hence the smashing of the unit as one single setting change cost me $600;) Either way, it wasn't stable in the past nor has it been today so to me, it was STILL worth a try. Damn shame the folks at Avin butchered the system up so damn much, it caused this loop. I say that because I have done this on a ton of units when running KitKat and never had this happen. I did check for ample disk space as it needs it for ART too, which was enough.
[Android Head-Units] CleanKM:
Ok. Don't switch to ART. Got it.:eek:
[Android Head-Units] jeffc83:
Correct and I am hoping this works tonight and/or Tommy can help! Just keep thinking what the button does except for "reboot" :D

I also found this unit, which has the same specs after investigating yet it was JUST released in August -> http://safedrivesystems.com/bmw-andro-10-3-touch-screen/

Shady you know what going on there as it TRULY just looks like a different launcher on the Avin screen.
[Android Head-Units] CleanKM:
Yeah I posted about it at bimmerpost. They supposedly demoed at bimmerfest this year. But my guess it's the same thing just rebranded...
[Android Head-Units] jeffc83:
Sorry man, must have missed a few posts over there!

I'm also going to play with the reset button as there mist be a method to boot to recovery.

Nothing is working so before I get really upset, I'm just going to stop and wait for avin to reply. I want to be sure that I cannot boot into recovery using the reset/combo of buttons before I uninstall it.
[Android Head-Units] jeffc83:
The friggin suspense is killing me but Avin got back to me with a possible solution. It's a program that creates a bootable SD and I am praying to the Android gods that this will reverse the runttime change. If not, I'm gonna have to fess up and tell him what I did and BEG for a recovery image. :cyclops:
[Android Head-Units] CleanKM:
What's the program? If they share those things then let me know, I'd be interested in having a copy.
[Android Head-Units] jeffc83:
I don't speak nor spell Chinese so I can only tell you that it is a program at the moment LOL! It's working but it is not an update tool, it is a recovery tool so this will take a bit. I have to be thankful as this is even better than I expected since it creates a bootable SD. I will ask if I can share the files and instructions here and if he says no, I'll just send you the files via PM so we have something to fall back on in an emergency. It may wipe the device but it deletes it ALL including the bootloader, which is fantastic. I think I'll try swicthing to ART again:silly::rolleyes: Avin support rocks and I have a sneaky suspicion that Tommy knew what I did. I probably shouldn't have asked him to edit the build.prop for the next build and which line of code to edit for our time issue;) I also asked if I could send a few bucks to buy him a beer and am willing to on this one lol.

Okay, he kindly declined the brewski and also asked me never to share the files so I cannot. It's a tool that not only could fail but there are too many issues that could arise if this gets out there. I'm just thankful he understood what I did, why and wanted to help anyway. I'm also hoping to help him sort out a few things behind the scenes once I get up and running comfortably again. (not rooted again, haven't pulled anything nor have I tested these edits) I'd prefer to work with him on making a recovery image of MY setup but it's a lot to ask so I'll tread lightly this time:p
[Android Head-Units] CleanKM:
That sounds awesome. Keep us updated. Hopefully it clears everything out. I'd be interested in the MCU and APP version after it comes up so we can compare. Does the program download the latest file from somewhere or is it all included in whatever he sent you?
