Caska Android 4.4.2 2 din

Has anybody managed to root android caska 4.4.2?
Thanks

Anyone?
It says:
mcu: v3.00h7_ca712_f7e1430
kernel: 3.0.36+
android 4.4.2
Thanks

Also looking for a way to root this HU too.

Why don't you just flash Malaysk's ROM? It's easier and the ROM is much smoother than stock.

I've never used Android, I'm a iOS user and very afraid to brick my unit. I just download ROM for 4.4.2 and boot it according to the instructions?
My unit shows:
MCU Version: V3.00F8_CA380_E55B_ECI1455
Build number: D200 Ver2.01 20141228.2309
TCON Version: V6.00_HSD80_EC28e
Many thanks for your help!

I actually tried a Malaysk's rom and It gave me error in the middle of installation. I had to return the original rom. Not quite sure if I used the correct malaysk's rom. I have a rk3066 android. 4.4.2

Hi Guys,
I also have a similar unit. Did you manage to make a backup of current image? I want to upgrade because I have two issue: sometimes the unit doesn't complete the startup and I can't use sygic navigator.

By your username I assume you're brazilian, right?
Where did you buy your unit?
This night I've managed to talk to a Caska sales director for LATAM and he said that they cannot give the stock ROM for security reasons. I still have problems with the clock and the startup also (blank screen). They say their engineering team is working on fixing that issue, but China has a holiday that starts today (Oct 1st.) and only ends Oct 7th. So I'll only have an answer after that day.
Maybe you can talk to your seller and see if he gives any support (I bought mine at www.rcmultimidias.com.br).

Sure I am, you are right.
I bought mine from aliexpress. I found a update.img file in some folder, but I'm not sure if it is the full image. I opened that image in a linux box and looks like we have everything, there some ext4 images, boot image and a lot of other files, but I'm not 100% sure about it. May be somebody with experience could verify that.
Another annoying thing is the music and video apps not reading files from sdcard, they only read USB and inand. I've modified the Music app to point it to the correct path, but I couldn't install it back to the unit (It fails to install without any error). At least if I could reassign music and video buttons to another app, that would be ok (VLC is working fine, just need to adjust volume).

Normally you have to boot in recovery mode, something that I still don't know how to do for this unit, and then use that update.img to restore. See this thread http://forum.xda-developers.com/showthread.php?t=2660662, there some possible procedures there and may be one of them work for the caska.
How big is the update.img file they sent to you?

Yeah. I have tried everything but could not boot. It is just a blank screen.
Here you go with the update.img.
https://www.sendspace.com/file/mjkgfj

Here I posted a video with all the problems I'm experiencing with this unit. The main problem is that I cannot setup the right time, so all Android apps are useless (they require a secure connection to their servers and this is only allowed with a valid certificate [that needs the correct date]).
I was trying to root my unit so that I could use ClockSync to fix the time every 30 seconds (it resets after 1 minute), but had no success on that.

Hi!
So, where did you managed to talk to Caska? I've tried contact with Caska Brasil with no success (they say they do not offer support for Android units), and Caska Global didn't give any answer ([email protected]).
I've downloaded your update.img, but it's for CA712 and my unit is a CA380-XLA, I'm afraid to brick it. Have you tried entering recovery mode pressing reset and power buttons the same time?

I can reassign the screen buttons in my unit. In the settings, go to the last menu: "Shortcuts". Not sure if there's a way to reassign the physical buttons without modifying the original ROM.

I'm newbie as well, but I know that you must need possible clue, since you brick your unit. I'm afraid to point you to the wrong direction, but I believe it deserves to try. I saw some threads discussing about the bootloader and connect via USB. Looks like to have to install the usb driver for the rock chip (RK3066, since it is dual core and there is a file RK3066Loader_uboot_upgrade2_4_16gok.bin in the update.img file). I don't have more details on that, but may dig deeper.

I've tried pluggin a USB to the unit and connecting it to my PC with no success, no devices are recognized. I have developer mode active but no options to enable USB Debugging.

So, I was able to extract all APKs from the file danylam hosted, and it's quite different from my unit: I have only one "Settings" menu, and in my unit some essential apps weren't installed (like HBS_Carkit_ChangeLogoUtil.apk and HBS_Carkit_SyncGPSTime.apk). I've installed them and solved one of my problems: car starting with a GMC logo. But the SyncGPSTime.apk isn't being called by any applications, so it's not starting (and I cannot start from itself).
Then I tried installing the Settings.apk that came with the ROM and ended up with a non functional setup menu, unfortunately. Since in that version most settings are changed from the "Android Settings", and I couldn't install that apk (it shows me an unknown error), I've lost some essential menus.

This is the linux tool to open the image http://forum.xda-developers.com/showthread.php?t=2257331
command:
Code:
./imgrepackerrk update.img
It creates a update.img.dump folder and the bin file should be in the update.img.dump/Image
Boot.img is compressed and if you want to see content do this:
Code:
mkdir boot
cd boot
gzip -cd ../boot.img | cpio -i -

Tried searching mine but couldn't find any *.img files. But at least I've managed to uninstall the CA712 settings from my unit and revert to the original one.
Looks like your unit is a little bit different from mine.

Erisin DR7090 MCU has stopped , Need to reset the unit

Hello, my device says MCU has stopped and i can't touch on my screen to make factory settings
Can someone give me some help?
What do i need to download to make the reset?
I search for hours and hours and nothing.
Thank you so much

Tried this from erisin website
E0056 ES8990G(Android 4 Core HD V2.72) Stuck in boot screen or other problem
I read the instructions, and when i start the device with file in sd card, it does nothing

Ok
Touch is working again, i download some kind of LM software and its working
But now the screen doesnt retain anymore. and most of the buttons doesnt work
Maybe i just install some kind of rom for 2 din head units
Still looking for original software to install on my unit
I email Erisin but i don't think i will get any aswer, the costumer service looks very poor

Finaly spoke to Erisin
They say that the head unit is not from their brand
What brand is this? Can someone tell me?

Installed the wrong software on it
It works, android looks the same, but i don't have bluetooth option and button to move screen doesnt work
How can i delete this " rom " ?

Here's correct firmware of not Erisin "DR7090 1 din android car head unit stereo, Android 4.4.4.'', 1024x600 resolution.
1. Please confirm the unit is in "off" condition
2. Copy all files (not folder) into a SD card root, plug the SD card into GPS card slot, turn on the radio, it will begin to update automatically...
3. After "OK", unplug SD card and restart unit.
1721831 DR7090 Update.rar

I have the same DR7090 radio with the same firmware uploaded by demiro and I still have bugs to use.
Do you know the brand or if there is already more updated firmware ??
Or if there is some alternative ROM that works better ...
Greetings comrades!

MCU version of Erisin ES6292B 9" PX6???

I received an Erisin ES6292B 9" PX6 for Mercedes Benz.
I don't know why but for some reason I was sure it was a MTCD/E version so without prior checking, I immediately went for the upgrade to Hal9K MOD.
The upgrade finished and the unit rebooted. I am not sure if I saw the boot logo (I think not) but as if this was not enough, during first boot, someone in the workshop cut the power to the car and the unit was bricked!
I wrote to Erisin and they sent me the Stock image to try to apply from recovery. However it is impossible to enter recovery with any way I tried. As long as I hold the reset button the unit is dead. When I release it the backlit starts but the screen remains black even after 10 minutes. No recovery, not even boot logo! It seems the MCU firmware is corrupted.
At the moment I have an ST-LINK/V2 programmer in my hands to go for unbricking with Wadzio method but STILL NO ANSWER FROM ERISIN IF MY UNIT IS MTCD/E or different.
Anyone knows?
Also, anyone knows a direct link to download recovery.bin for my unit?

What are the names of the files that were being applied for upgrade? Are you able to share these - assume you had two files, one MCU and the other android.
Also the stock image ersin supplied.
Note the wadzio Unbrick is for MCU unbricking, are you sure that the MCU is bricked? I.e. you are sure you were upgrading the MCU, because from your description, sounds like you were upgrading the SOM/Android.
Details are everything.

This is the link to the Hal9k PX6 Custom ROM
This is the link to my unit's stock ROM
I assume my MCU is bricked because I cannot enter recovery

When there is no boot logo, I guess it is the MCU. Correct?

The zip doesn't contain an MCU, and is an android OTA zip, therefore if your power outage occurred while applying this file, the SOM emmc/nand is probably corrupt, and you might not be able to enter recovery.
I've had a number of SOMs sent to me exhibiting the same symptom, so not uncommon.
If unable to SDCard boot, SOM recovery via OTG is the likely path to recovery. Refer my threads/signature.

I still have not managed to find out if my MCU version is MTCD/E or other. Still waiting for Erisin's response. They requested a video with symptoms which I already sent.
Supposedly my MCU's version is an STM32 and I tried to install Hal9k's ROM (specific for MTCD/E) wouldn't that corrupt the MCU? To my thinking, this is the most probable scenario.

The files you list are not MCU updates.
Its trivial to determine if you have an MTCD MCU using Wadzio's decryption tool, however & once again, the MCU is separate to Android. You cannot flash the "wrong" platform MCU (ie. MTCD vs STM MCU) in recovery.
Once again; the files you list are ANDROID and not MCU. Unless you havent described what you were doing to "upgrade" the unit, which lead to corruption; the SOM is bricked and not MCU.
Again, for clarity, MCU and ANDROID are not the same. They are separate images and cannot be flashed together.

Kind of getting there. Ha ha, my knowledge is very epidermic! Tomorrow I ll try the SOM recovery via OTG as you suggested and report. Thanks for your time

Just a (silly?) question: Could we say MCU is equivalent to bios on a PC and Android is the equivalent to PC OS? If the MCU (=bios) is still untouched, even with Android (=PC OS) corrupted, why is it impossible to boot from SD or simply access recovery?

For sure your MCU is STM32, as mine.

The MCU is more like say an auxillary fan and button controller, connected to a serial port, but still controlling the power supply to the computer.
Why impossible to boot or access recovery - corrupt emmc/nand.
Your unit doesnt look like an MTCD/E device.

Unfortunately hardware used in my PX6 implementation is quite different from what shown in SOM recovery over OTG page. I don't have the tools needed to uncover the SOM (75W soldering etc). Judging from the bottom, it seems the SOM is embedded on the mainboard and there may not be any pins accessible. However, rk3399 supports what is called MaskRom mode (a relevant link translated from Chinese) allowing programming of the SOM with the use of a male to male usb cable. But this would be possible only if we access the interior and find that the test points to bridge exist. My last resort if nothing else is possible.
Another issue I am facing is that my firmware is not in update.img format but comes in .zip split in several files. I think I need to repack it in .img format in order to be able to program my unit with existing tools and I don't know how
Just a last (stupid?) question. Accessing the MCU via ST-LINK/V2 programmer is possible. If we new the starting memory address of the SOM firmware or the various parts, would it be possible to flash from there?

It is an STM32 eventually. I managed to unbrick it but the MCU was changed. Both firmware and config. I am stuck with an 800X480 desktop on a 1024X600 display.
Can you export your MCU.cfg file and send it to me please? I think you need to go to settings/about then toggle between Kernel Version and OS Version 6 times in total to enter hidden menu. If a password is asked, try 666666 or 123456. From there you can go down and select export config.
Thanks in advance!

Need help with Android upgrade after bad one

Hi All,
I have a 1280x480 8227l headunit.
It was running android 8.1 and I had a few problems. I found a junsun upgrade on here I thought great!
It didn’t use the ‘update android’ button in settings as the instructions were to put the bin and upd file on a flash drive and reboot.
I did all this however the resolution is all wrong I’m missing a chunk off the bottom and the side is blank. I can’t find anyway to fix this.
A bit more google provided me a couple for 8227l firmwares for 1280x480 unit.
The problem is they are just zip files and the option is no long there for update android in settings? Is there a way to manually do this or something?

podofo android head unit zlink not working after trying to update

I got a podofo head unit radio from ebay at the beginning of the year and just recently tried to update my zlink to the latest version but was unaware that there are a bunch of different zlinks for different radios. After the update my zlink gave me a error code that said "Channel Err! CHANNEL-MISS-MATCH Apk:[zhangxun]". Then I contacted the manufacture who told me to contact the ebay seller and the ebay seller isn't replying. Has anyone else solved this problem? All I want is a functional zlink. I've seen online that apparently I have to update my android radio but I cant find a site to do so.

These are pictures that might help show what Im seeing.

That error message you are getting is giving you some useful information. It's telling you that you need to be have the zhangxun channel version of the software in order to recognize the license that came bundles with the unit. I would advise downloading the version 5.3.31 zhangxun firmware from here and following the instructions in that post. It should update you to Zlink5. If you have an issue with wireless android auto working on first attempt, try disconnecting your phone bluetooth, then reconnecting to the head unit bluetooth again while Zlink is open.

I downloaded the 5.3.31 to a usb drive plugged it into my radio and did the android update from the radio settings but now my radio keeps restarting. It starts up to the regular car dashboard for 15 seconds then says shuts down and restarts.

Can you get into Apps and notifications long enough to uninstall Zlink? If not try loading 3.9.44 from a USB thumb drive and working up from there. Make sure the file is on the root of the drive with nothing else on it. You can also try to use the reset button to see if that helps.

I tried the other files by putting them on my usb drive but i cant go the the android update through the settings because the radio keeps restarting. These are pictures showing the process it takes

Should I try the zlink apk's as well?

Unless you can uninstall any existing newer installed version of Zlink the apk files will not work. On the other hand, he gzipped files can overwrite whatever is already there. Looks like from your screen Zlink5 actually installed. By the way, just use the 4-pin USB connector when attempting updates just to be on the safe side.
It looks like what is happening is a bootloop following a failed system reset. Did this happen following the Zlink install or after pushing the reset button?

Looks like from your screen Zlink5 actually installed. By the way, just use the 4-pin USB connector when attempting updates just to be on the safe side.
It looks like what is happening is a bootloop following a failed system reset. Did this happen following the Zlink install or after pushing the reset button?

I'm sorry you got hit by this. Maybe you should cross-post this to the [APP] Z-LINK Channels thread with the screen pictures in case someone else has seen it happen.
