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.

The only way to talk to caska global is using skype (coagent,service). Normally they are online at 9pm (Sao Paulo time).

I found the update.img in my CA712 with a simple search for update.img. I used the file browser and and did the search from / device.

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.

Help!! Bricked Seicane H605E t3 k2001m Android 6.0.1 Head unit

Guys I have a huge problem. I searched day and night for the last couple of days, still no solution for my problem.
I bought the cheapest Seicane head unit (model H605E). It's one of those head units that doesn't have any depth. It's very shallow/thin/short however you may wanna call it. It doesn't have an SD CARD SLOT or any PHYSICAL BUTTONS, just a touch panel. Specs showing on their website and in the settings of the device are:
QUAD-CORE T3 K2001M 1.6GHz
16GB ROM
1GB RAM
Rooted my device with kingroot. installed CPU-Z and ES file explorer. Noticed that the actual RAM was 752MB. From which the half was being used all the time. Actual capacity was 1.94GB not 16GB. From this 1.94GB only 1.5 was usable. There was an additional 10GB of space showing on the board as an sd card. Weird thing is that my device doesn't have an sd card slot. CPU clockspeed was 1104MHz.
Anyways I couldn't even run spotify in the background. It was auto killing all processes in the background. Actually pausing not killing. I searched the net and it was supposed to be power saving mode causing this. Funny thing is my head unit also doesn't have a battery. So whatever I did I couldn't solve the problem. I even accessed all the additional settings with settings editor pro. But no luck. So I decided to delete some system files with system app remover. Till finally everything seemed to stop working.
It was time to do a system restore. Oh forgot to mention I did one succesful system restore earlier. Anyways this time, it gave me the option to format my sd card. So Again.. I don't have an sd card slot. So I thought "Yeaaah, why not?" It rebooted and now I'm stuck in an infinite bootloop.
It's giving the following error:
supported api: 3
E: Failed to mount / cache (no such file or directory)
Rebooting..
I contacted Seicane and they're not exactly the most helpful reseller. They ignored my questions about where I can find a stock rom. I did find one on 4pda tho. I think that one should work. So far so good right. I ordered an usb male to male cable. Because the only slots the head unit has are 2 usb slots. I didn't succeed with connecting tho. It's not working. I totally bricked my device and in desperate need of help. And no, there's no one on the internet with the same device and/or problem.
Any help with telling me how I can put this thing in recovery mode (because of the absence of pysical buttons) and how to flash it would be greatly appreciated. I tried with phoenix suit and live suit btw. Maybe I did something wrong I don't know.

usb bridged cable?
My ordinary male to male usb cable doesn't work for the connection. Would a usb bridged cable do the job?

You need a USB SD card reader.

You need the correct firmware before you try to get into the recovery. At least the firmware on the SD card would open the recovery itself.
Manually there are at least more than one possible options to get into Recovery:
Long press of the reset button (until your softbuttons are blinking)
Pressing the reset button and volume up or down
Pressing the reset button in combination with any other soft button
...
...at least: You should ask the seller for information and firmware. Without firmware you are not able to get the unit back to life.
Ah... the hardware contains a so called SD Card, called "Internal SD", this is correct so far.
If your uni does not have the RAM and ROM which was written in the shop... send the trach back and use some more money to get a good one.

Thanks a lot man I will try it tomorrow with a usb card reader. I need to buy one. Here’s the thing with sending back. I paid $69.99 for the device and $28 for shipping. So they’re only refunding 69.99. I also have to pay money to send it back to china.
Thus it’s not worth the trouble of sending back and waiting for a louzy 50 dollars. That’s the reason I rather save the thing than waiting another month.

The USB sd card reader came in. But still no luck. At this point I'm not sure about anything anymore. I really really really have a giant urge to smash this thing to pieces. Rather on one of the employees head from Seicane. Doesn't matter who. Just anyone from their company will qualify for this ****. So if anyone wants to volunteer feel free to pm me.
anyways, any other ideas?

i have the same problem
Did you have any solutions ?

Had the same issue. The HU (with 2 USB ports) was some unknown brand called Funrover loosely based on Joying firmware. What worked for me was
- Download the suitable firmware
- Extract it on the PC and then copy the firmware files on to a freshly (FAT32) formatted USB drive
- Plug in the USB drive to your HU USB port (1?)
- Since your HU is already bootlooping, plug in a keyboard and use the following key combination> Alt + Print Scr + tapping i (or e, both worked for me) to get in to recover
- Ideally the recovery option will detect the plugged in USB and start reflashing the firmware so that you will be able to use the HU again.

Hi. Was it running fine b4 rooting? Or it went weird after kingroot?

i have same unit and its workin with some problems. if you help me i can backup my unit rom vs whatever and upload than share with who need it.

Do you place firmware files into directory alone, in zip file? what format? Mine doesn't seem to recognize the usb how I have them.

Extract the zip file your downloaded on the PC itself and copy the extracted files on to the USB so that all the files are on the root of your USB.
eg: If your USB is F: drive, the content would be (For Sofia 3GR)
Code:
mcu <- folder
oem <- folder
5009_20.zip
5009_60.zip
bootanimation.zip
Allapp.pkg
config.txt
crruptoff
customercfg.txt
logo.bmp
rksofiacfg.fg
SQLSOFIA

I have the same unit but with Android 7 and I fight the same problem with auto-killing apps.
Have you tried putting spotify to sys.keep_app_1 in /system/build.prop?
I'm hoping you recovered your system.
Edit.
Actually chemixzgz's tip helped me solve app-killing issue. Apps need to be added to Whitelist in device settings.

Followed everyone's suggestions, nothing worked. Followed videos for taking unit apart to reset battery. (find on you -tube) easier than I imagined. Recharged battery and it works. Wasted 2 days trying software fixes.

Boot up / unlock password

Bit of a strange one.
So my Android 8.1 generic car stereo has been working perfectly for a few months. Today I locked the stereo on my Google account not recognising it as my car stereo under devices. I finally managed to unlock it on the car stereo, but am now left having to enter the password on the stereo everytime I boot it. I have even changed my google password and removed my Google account from the stereo and it still asks for the password used to lock the device remotely.
I've reset settings under the car settings menu and no joy. I've noticed that in the settings it shows logged on as the name which I set the device as on the Google manage device settings, but I can find no way to remove the password associated with the profile or just remove the profile. It appears the profile is now on the stereo and I find no way to change the settings etc.
How the hell do I stop it asking for a password and just boot normally again.
Thanks. Mike.

I had prettry the same issue with my Android HU.
only way was to perform an OTA Update with full data wipe.
at my unit i had to add "_format.zip" to my file, and then performed the OTA update, this way the system was truly virganized.

Ahh ok. Where do I start with this. What do I need to do.
Thanks

You have to ask your vendor for an OTA update, maybe he also can tell you how to rename the file for your device.
Then you need to put the file on a Fat32 formatted USB Thumbdrive (best not over 16 Gb large).
then just plug it into your device and wait until the "Update" message does appear.
but as said before, you will loose all your afterward installed programmes, configurations and files.

Wondered if you could help me further.
I've been sent the 9.0 update files for my unit from the supplier which is good. The problem is that I cannot get the unit to recognise the files. I've placed the 2 files being a bin file and update file onto the root folder of both a USB drive and sd card. I've tried both and when tapping the screen on boot up it detects the screen taps but fails the update immediately saying, fail check usb and files.
I've tried everything do you have any idea.
Thanks.

So you got an update from your vendor from Android 8.1 to android 9 ?
do you have a picture of the exact error message ?
What are the exact file names ? or do you have a DL link to check the files ?

Hi, I have the same, but with Android 10. It can' remember settings, video out is not working, is overheating, lights under buttons don't work. Looking for a firmware for this unit.

For settings that are not saved: try to extract the USB stick from its slot, re-enter the settings of your interest and check if they are saved.
First, maybe do a factory reset.
For the firmware have a look here: https://forum.xda-developers.com/t/junsun-v1-pro-mtk8259-4gb-64gb-android-10-headunit.4193061/

Thanks man, pulled out the USB stick, it did saved the settings, but only hardware settings. Android settings like radio stations and equalizer or display and volume are still not saved. But, as I have put the USB stick back to the slot, everything is lost, don't save the settings. I think it may be something with file system. That's why re-flesh new firmware may help. Still looking for one. Seller refused send it to me.

You have to change the reading settings of the external usb stick. By default it is used as phone memory, instead it must be set as file transfer. Surely the problem is that at every restart the radio goes to look for the settings right on the USB stick, but system detects the USB stick only after it has booted, so it assumes the default settings, not the customized ones

Thanks, how do I change the reading of the USB stick. You know a lot.

Go to settings->system,->developer options-> default USB configuration, then choose "file transfer"

Thanks, I don't have there such a option. Now I can't see the file system.

Man, I put everything back together, reset, and get STORAGE/EMULATED/0 can not be found. And can't see USB. I don't know what to do. If you may have any suggestion, please. Now the radio is useless for me.
Thanks in advance if you may help.

To activate the developer options take a look here:: https://developer.android.com/studio/debug/dev-options.
To set the USB stick as file transfer go to the radio settings, select "info system", then "storage space", then "storage settings" and here select "internal memory" for all items
To detect the USB stick, first you have to format it in fat32, then reboot the radio and try to insert USB stick in both USB slots, one of the two must necessarily see it

Hi again, seller has send me a new firmware, if you will need it let me know. 8259P_芬那威UI01-国外_v9_20210820.zip
He claim that is the newest firmware. Just still don't know how to install it.

I'd love to have that Firmware... though i may just have bricked my unit :/

I see USB sticks now, just in the "storage space" don't have the option "storage settings" and "internal memory".

Try to dowload it here, it is pretty fresh link from today. If not, I will put it somewhere else.

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?

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.
