Caska CA712 4.4.2 Possible to upgrade to new ROM?

Hi all
I am the new owner of a Caska CA712 Android headunit. Pretty cool but couple of things. Firstly, Play Store is not working for me. No idea why. I have internet connection and all is good.
Other than that, the device is ok, kinda sluggish when running BT music. Interface kinda sucks and accessing different functionalities is kinda crap.
But besides that I like it.
Onto my question however. I have looked around to see if it is possible to install a different ROM but so far there is only really 1 thread about it and it is not really going anywhere.
From what I understand, Malaysks ROM has 2 different versions that work for the RK3066 and RK3188 and you use the one that is depending on your processor? Mine is dual core so from what I have read, I need the RK3188. My monitor is also 1024*600. That is all good. But has anyone bricked this device yet? Has anyone successfully loaded up the ROM with no issues? I read someone had an error half way and had to revert to the original ROM.
Does anyone have any info on rooting/installing new ROM onto this device?
Cheers guys and gals

Was messing around some more on the device there and figured out a few things.
Firstly, I get the suspicion that the firmware currently installed on the device is from a D200 android mobile. I realise of course that the build number says that its the D200 but kingo root clarified saying that the device was the D200 which it was trying to root.
Speaking of kingo root, doesn't appear to work. I have tried it several times and once it gets to 90%, it restarts the device. This may need to have a laptop introduced to it.
Turns out the Play Store worked all the time on it, not sure why it did not load before but all is good there.
Netflix works, Facebook works, everything fine apart from Google Play Music.
It opens the app but then just continues to load, then a black screen with no response from the app.
Another thing I noticed, I managed to install Kingo SuperUser app on the device (thinking it would allow me to root) and it showed a system app that is installed on the device called "RK K1102V1.1 ####" and then Chinese (hope that's not racist or anyting :S ).
Also, I tried to copy over the update.img file from iNand to card which is a 32gb sd card I put in but that did not work oddly. But someone here did mention that it was failing also because it wasn't named as "sdcard" or something along those lines.
Anyway, that's everything I managed to dig up from the device today. May take another root around (pun intended...).
Let me know what your thoughts are!

I have tried to install NewKingroot but it never loaded on giving me a failed error (nothing specific).

Thanks to wolf4.0!
This root (NewKingrootV4.82_C1) worked (sometimes not on first time - if it fails just run it again)!
Done at my HU (Caska CA712 analogue - RW6MS-33010-S1 headunit for Toyota Camry in variant 'Exclusive', made in Russian Toyota factory).
Tried some other programs before it - but they didn't works: Universal Root 1.6.9, Baidu Root.

Hello friend
I have a CASKA CA712-XL7 and it does not have the RK066 processor, has the ARM 32F101.
I took this photo inside the unit and as you can see it has that processor.
Excuse me, The forum does not permit me to link the photo, but I can send you by mail.

Sorry, but ARM 32F101 is just for MCU - not HeadUnit processor, and - as i see at aliexpress - CASKA CA712-XL7 has quad-core CPU with 1.6GHz speed (looks like an RK3066 or newer). You can try to download software like AIDA (from any apkmirror) and check by yourself.

My friend, you are right. Thank you.
¿Have you tried flashing with the Malasky ROM this unit CASKA CA712-XL7?
¿Is this reflashing convenient? ¿works?
Thanks for your reply

Did anyone manage to install new ROM on this thing? Or did root give any more functionality? Thanks

still would like to knowe best way to do a complete backup of factory rom and partitons ...thanks

unit came in the other day loaded up some the apps and all seems well.. so far im happy...

Thanks for reporting. What is the boot time? Is bluetooth working? Do you have any downsides so far with this unit?
Also, did you receive the firmware from the seller?

It's working good .can someone give me advice on the best way to root and backup original ROM/firmware.. what other roms can use with this unit... and if I were to root and something got messed up would a factory reset restore it to the state it was when it came out of the box

I installed TFS Launcher 3D shell, and it works fine and changed everything on the unit and it made it look great
The seller sent me a copy of the original ROM

I'm glad I found a thread about this unit. I bought the 2gb model. I'm generally pleased with it, but I have the weirdest audio "source" behavior.
For example Tunein radio will not output any audio at all. Poweramp will play half a track and then switch the output to the radio tuner, Mediamonkey will play a track and then switch to the radio tuner at the end of each track. It's incredibly frustrating!
Waze and Here maps' audio seems to work OK, and other internet radio apps seem to function OK. There seems to be no logic behind the behavior that I can pinpoint. Anyone got any ideas??? Perhaps there's a way of turning 'off' the radio tuner when it's not being used?
I very rarely post on forums, as generally I can find solutions myself in the end, but this one has me foxed!
Incidentally, I joined this forum back in 2004 when I got an original HTC-built O2 XDA 2 - seems a long time ago

Install Sygic on extSD. QuadCore-R16 1.6G

Hi, I have my head unit http://www.preston-i-c-e.co.uk/vw-006-oem.php but I think really an Audiosources D90-610, with iGo navigation installed, presumably a dodgy version as it came with it.
I already own Sygic with UK/Europe maps, and prefer this.
When I try and install it, I can't get the maps on anything bit internal memory, which is nearly full. I have 2 MicroSD cards, 32gb and 128gb visible in ES Explorer, but I can't get Sygic to work off them.
I've tried cut/paste the com.sygic.aura to the extSD, but it then asks me to download maps again on internal memory.
Any suggestions?

same POS
Hi Andycat,
Thanks for identifying the unit, also have one from same source.
All in all a disappointing POS.
slow boot, bluetooth drop outs ...., cant get to recovery or have perm root
Installed alk co-pilot to internal ( sdcard ) without issue , have you tried deleting the nav software and maps which came with the unit ? / factory reset ( this deleted the default nav app for me )
What have you got to fill up the internal ?
Passwords are as per https://forum.xda-developers.com/an...nd-generation-4-4-2-android-21u-ouku-t3230587
Kingoroot roots but only till reboot
Cant say Preston ICE either helpful or knowledgeable , nice touch putting usb chords into glove box, not mentioning vw input in arm rest no longer connected

Hi Ian,
I ended up putting iQNavi on it as a fresh install. I use Sygic as SatNav though.
Definitely a KItKat unit too, not 5.1 as advertised. Just hacked to look like it.
Does what I need though more or less. Radio average, DAB needs a better aerial. But use Poweramp for music, and iPlayer radio for most stuff anyway.
Keep in touch if you have any tips/ideas.

Cheers Andy,
suspected KitKat ( can't remember where/which but at least one screen says so ) - android names not so meaningful anyhow ( define loose set of software at various versions ... annually changed by Google , interpreted by vendors with the odd new feature ) and these are very grey units .
Intend getting the button lights to work ( orange wire not connected ) and moving usb to more normal place

What to do with the head unit?

I just bought this unit off amazon.
It's a Podofo Android 2din with 8.1
I hate the stock user interface. I've tried using some of the launchers like webcarguru but every time i switch back the the home screen my bluetooth music stops or the built in radio app stops. i'm just sick of seeing Adele on my home screen. I like the other UI's like UI4 and UI5. How do i switch to those?
I also hate the fact that my iphone can only play via bluetooth and only charges via the cable.
I know it's not a fancy radio but i expected a little more i guess as far as tailoring it to my needs.
I want to tweak the radio but I haven't really gotten any straight answers as to what my radio actually is by just searching and what root will work or which firmware or roms to use. Any help is appreciated.

Well I bought it because of some misleading info on Amazon. I tried to return it and they ended up refunding me but letting me keep the radio.
Now I just want to improve it. Different UI, add subwoofer output. It looks like from what ive been reading it's a matter of rooting and finding the right firmware. It seems like this unit is the same as all the others people are modding or updating.

Hello, I bought this unit too (the exact like martinique78) but my unit is total waste of money, it can't even properly go on playstore to update it own apps, do you guys have this issue too ?
I cannot install a single other app, I already tried deleting cache of playstore and so on...
Thanks

I didn't have any issues with the play store on the stock rom or the one i'm using now.. I did finally find a better ROM for this unit and flashed it in. I also relocated one of the video out RCA's to the subwoofer output pin to get sub control.
Basically I have been reading and tweaking this unit to make it what I want.

HI,
do you have a link and "how to" for installing the alternative ROM ?
I`m looking for a rom/apps which shows album covers for music and have an RDS-Function.
At first I had some trouble with the battery, too as the device did not turn off when ignition was off....2 days later battery down.
I had to remove a cable connection and now the radio is out when i turn off ignition and put the car key out.
Hope that the (new) battery now lives for the next 5 years...

I don't know of a good link that describes the process very well. A lot was taken from a russian site using google translate. I can describe what I did that worked for me.
1. Get SPflash tools - https://mega.nz/#!LAl1FI6D!CJa2AHokZkZj120q5C4Dn_vuPeea-N6eSp2FJ6js2xY/view
Install the drivers for mediatek located in the download file. (this will take a while and give you warnings for possible risk installing) If you have windows 10 there is more work needed to install due to security. Just look up installing mediatek drivers on windows 10 for a youtube video.
2. Get or make a male to male type A usb cable.
3. Open flash tool click download. Choose (MTK_AllInOne_DA.bin) for Download agent. Should be located in the Same extracted folder you opened up the flash tool.
4. Locate a rom that works for your version radio. Should be YT9216/17 or YT9218. This is the rom I am using right now. Only flash this if you have the same radio as me.
https://drive.google.com/file/d/17cFt2W7YaKiA20TilCP5bF6lJhsIfYEl/view
5. Choose the scatter file inside the folder of whichever rom you downloaded and load it into flash tool where it says scatter-loading file. Go down to the list and and check every box but UNCHECK Preloader. Hit download button.
6. With the radio powered up, plug in the male to male usb cable into USB-1 on the radio and the other end into your computer. Hit the reset button on the front panel. You should see hear the laptop connect and the flash tool should show download progress. DON'T REMOVE POWER OR TOUCH ANYTHING!!!
7. Once you see download complete on the flash tool, remover the USB from the radio and hit the reset button on the radio again. The radio should reboot as normal with your new rom. It will take a while for the first boot but after that it should start up right away.
Post the about device info before you do this though so I can tell you if it is the same as mine. As for finding apps and roms that work for you it's just a matter of trying each one out.
Are you trying to see album art from a memory stick, usb connected music player, iphone or android phone, bluetooth? Depending on what you're trying to use it's a different route or not possible.

Trying to identify a UIS8581 unit

Is anyone able to help me identify what unit this is? Its meant to be a higher end unit but finding it really sluggish and also looking at some of the reports its using > 6GB of ram OOB out of 8GB (Not sure how the 2GB unit would have worked) .
Sometimes when turning it back on from standby when playing music etc its really jumpy as its its doing something in the background. Anyone got any recommendations on apps to show what using up all the CPU?
It appears to be a UIS8581 based unit, I have run the HWGetinfo tool on it but its reporting its not a FYT unit.

This is a completely known unit in here. Try search yourself in this forum for ZLA_ you won´t find anything.

Bit harsh - I have been search but how am I meant to know to search for ZLA not ZLH? Also, searching for "ZLA_" returns a total of 1 hit, a google search for `XDA developers "ZLA_"` also returns just a couple hits not in this forum?

I'm also with the same thing.

ZLA was a typo... sorry.
My posting was not meant to be harsh, but this unit is really completely unknown on XDA.

Yeah that looks like the BMW equivalent to mine with a slightly different CPU

Talking with the seller, mine was sold by COIKA.
It seems that it follows some patterns that are very similar to other HU's, you just need to make the following to update for example, the boot logo:
Folder structure:
- HUTUpdate
- OS
- bootanimation.zip
- logo.png
- upgrade.en (empty file)
- upgrade.system (empty file)
So, if you find other examples of HU types that are Android-based, this may work.
To upgrade the MCU is
- HUTUpdate
- mcu
- upgrade.mcu
- BMW_8581.bin
I was trying to make backups with other tools, but no success yet.

BMW_OS_8581_1920_720_1.86.zip
drive.google.com
This worked for me as an update, but I have a BMW. Hope this helps!
Just unzip the HUTUpdate to a blank USB

Which HU do you have?

I have also an UIS8581 Unit von Coika. I have software version ZLH_AD_OS_1.86, and MCU LZH_qxha20830A_Q3H0_8581...
I have also some problems... the bluetooth does only work as a headset. you cant switch it on and use it as a normal conection for apps.
Once you switch to original system and then back, all apps are closed( spoitify etc) you need to restart them...
also my sim does not work at all, cause there is no APN setting in the system. once i try to enter it it says user is not able to change settings...
all in all the system is nor really well programmed and has lot of bugs.
If there is anyone who can help with get all the normal functions back pls contact me?
Best regards

I use my phone via original Bluetooth on the car. I don't use zlink anymore. As I have the headunit online it makes it easier to use gmaps etc directly.
Do you have a SIM card installed? Does it work? My one does not connect as there is no apn and I cannot set new one. Did you bought it from coika?

i use only zlink...because i like the home of carplay..i don't use the sim card ...yes i bought from coika by aliexpress. for me you need disable original bluetooth of car..and use only headunit..one question..but the our unit is mtcd?

I don't know who is the main manufacturer. Coika says they are the own manufacturers. But don't belieb them. Struggling with the service people since days... Apps are closing after you switch to car system... bluetooth is only working with mobile phone...no obd device etc... SIM card is not working...but they keep me waiting

Similar unit here (Mercedes version):
Version: ZLH_BZ_OS_1.80
MCU: ZLH_BZL221030A_8581_13
Android version 12 (fake - it's 10 - see below)
More info in attached photos.
The 8888 code gets you into factory settings, as in this thread: https://forum.xda-developers.com/t/...-not-fyt-based-read-first-post-first.4525675/
I installed the "Fake Device Test" app and it closes after 1 or 2 seconds (possible sabotage by the device?) but I managed to get the OS info by quickly flicking down the screen while videoing it, then playing back in slow motion. This confirmed the Android API level as 29 (ie Android 10). It also seems to confirm the claimed 8GB RAM and 1920x720 screen are correct.
I want to have a poke around with ADB and busybox, but so far haven't been able connect. The unit claims to be rooted.
Wireless Android Auto works, but one minor annoyance is that my phone seems to give up on Android Auto before the unit is ready to connect. A quick toggle of bluetooth and reconnect to the unit once it's ready is necessary. Also, you need to use a cable for AA when the ZLink app on the device is set to HD - wireless AA on HD delivers a pillarboxed display.
And despite all the images on AliExpress showing 5 icons per page in the launcher, I've only got 3 per page. Is this launcher configurable?
I don't know why exactly, but I have a nagging suspicion that the screen might be a lower resolution than reported, I need to see what the kernel/sysfs says. Do these units have a dmesg somewhere? Or could there be a problem caused by the screen being reported as only 7 inches, as I saw in the output of one of the System Info apps I tried? (Screen is actually 10.25 inches.
One thing I really want to do is get a full backup in case of future problems. Is using TWRP possible on these devices? There is a 1.5 GB "update.zip" on the internal storage, I need get a copy and examine it.
Investigations continue, I'll report back. In the meantime, does anyone have any thoughts on the above?
