Volsmart, 5.1, RK3188, root?

Hey guys! Been out of the rooting game for a while now. All these locked bootloader nowadays has that effect. Thank God for the Chinese! I just ordered a android head unit for the car from Amazon :
Volsmart 7 inch Android 5.1.1 Car Stereo Lollipop Quad Core 1024600 Capacitive Touch Screen without DVD Player support GPS Navigation Radio Bluetooth OBD2 USB SD WiFi ScreenMirror Backup Camera https://www.amazon.com/dp/B01FVV8U2M/ref=cm_sw_r_other_apa_5jF5xbJ1VW5C8
And I'm wondering what the root process is like for one of these. I'm not sure sure if I should be looking for this specific device, or just something generic based on the software version for instructions. Can anyone point me in the right direction?

I have Volsmart 5.1 Mtcd-kgl mcu version 1.75_1. If your Mcu version is older, you can ask the seller to give you the latest firmware.
You can use Malaysk MTCD ROM.
I used Malaysk Rom v5 and then upgraded to V6. My HU is running without issue. Malaysk ROM is a pre rooted ROM.
Make sure that you know how to get to recovery menu of the head unit.
Right after upgrading to Makaysk ROM, it is hard to get to recovery to clear cache and data. Keep trying several times, you will be able to. After this, getting to the recovery is normal.
If you don't want to use Malaysk ROM, use Kingo Root, just follow the Xposed LP thread under MTCB development. I did try it successfully before I used Malaysk ROM.

So basically it's just as simple as flashing a different rom, eh? Sounds a little too easy lol

Got it all installed over the weekend. Working great!

Volsmart firmware
Hi guys
I bougth a head unit Volsmart android 5.1.1 for my Toyota Corolla 2009 at Amazon.com.

Do you have a link for the latest mcu update? The people at Volsmart have not been very helpful with my inquiries.

mmm... MTCP? not MTCE?
Compatibility with MTCD/MTCE (this forum section) is not very clear...
BTW, this section is for the software development... you should ask in the general sections...

Yes, MTCP. As far as i understand P - is for 8-channel audio. Maybe there are some other differences, but this is the one i'm aware of.
Can you please share what you have? i will try to check if it can be flashed on my HU.
Thanks!

I have a MTCE_HF with MCU v. 3.30 (the latest known on the net), but I suspect it's not compatible with your HU, but anyway you have already a v 3.30, even if it's a v. 3.30_1 (for MTCP?).

Hello everyone. I received an updated Firmware directly from seicane for their head unit. This is Android 10 update for the 2/32 GB unit. Everything seems to be working great so far on unit. If you would like to try it for yourself please feel free to download and install. I'm not too tech savvy so if you have any questions I'll answer them the best I can. Thought I would share for anyone to update their own unit if possible
PLEASE BE ADVISED YOU USE THIS AT YOUR OWN RISK!
I will not be held responsible for any damages done to your own unit.
Thank you!

MCU Update before Hal9k rom install?

Hi all.
I would like to try the Hal9k rom update [ROM][PX3][RK3188][Nougat][7.1.2] Hal9k ROM 2 for ALL RK3188/PX3 MTCD/E head units.
I have an Erisin 3015v hu which is a PX3/ RK3188/ 1gb ram /2gb rom unit, MCU ver MTCD_LM_V1.56_1 Android 5.1.1.
Hal9k recommends updating to the latest MCU version before updating the ROM.
I have found MCU versions up to the lastest one I can see which is MTCD_LM_V3.06.
Does anybody know if there is a limit on how high you can go with MCU versions for units with this particular cpu / memory configuration.
Thanks

A little late but, it's always advisable to update your MCU to the highest (newest) available version (making sure it is the same letters)
eg: MTCE_GS_xxxx must be updated with an MTCE_GS_yyyy with higher yyyy's
You cannot update with MTCE_HS_yyyy as they have different letters

It is probably not a good idea to update MCU right before installing Hal9k or any other ROM. So like if you updated MCU, then straight away install new ROM, and then start experiencing new problems. You would have just made 2 pretty significant changes to your unit. How would you know which caused the new problems, the MCU update or the new ROM?
Perhaps a better approach would be to update MCU OR ROM first, run with that for a week or two, if no problems appear - then update the other.

MTCE Head Unit resolution problem, no usb, how to change DPI

Hi All,
I have a MTCE unit in my car.
With some tinkering I've managed to unlock its potential, Swapping the launcher, customizing a bit and so on.
The only thing that bothers me a lot is that the units DPI or resolution is ridiculous, every app is barely usable everything is huge.
the units screen is 800x600
and this is its info:
Code:
Model
A-MEDIA AUTO (800x480 O)
Android version
6.0.1
Core version
3.10.0
[email protected] #1320
Build number
px5-userdebug 6.0.1 MXC89L user.hct 20180130.142324 test-keys
MCU version
MTCE_HZC_V2.75b_1
CPU
8 core 64-bit CPU Cortex-A53 @ 1.5G
Memory
2000 MB
after searching the forum and the internet:
there is no obvoius usb connection for ADB, or wireless ADB
only 2 sd slots and a mini usb connector that apparently doesnt even work
no root.
no secret menus with passwords in settings
is there any way I can change the DPI on this thing?
any help would be greatly appreciated.

Your question is much better posted here: https://forum.xda-developers.com/f/mtcd-software-development.7379/
I´ll ask a mod to move it to there. May be have a look around there.
BTW: You really need to upgrade your unit to at least Android 9.

It has a bit issues with the Memory, but I think it would work fine... and you would be able to root, or use a custom ROM with it.

The resolution is changed using the dmcu.ext file. Choose the resolution of your inclusion, copy dmcu.ext to the sd card and update the MCU.

If you want to update the MCU, then yes. Before updating, save the settings in the dmcu.cfg file, it is a backup of your settings, in case of problems with dmcu.cfg, you update the MCU and everything will return to the original settings. Factory settings/126/EXPORT, you can find the file in the root directory, take good care of it, save it to external storage.
