So you installed with that guide? I believe that the guide is the same that there is on 4pda in Russian. When it arrives in other languages, it can change exponentially. It is true that it is not long to put into practice but also a small mistake, it becomes fatal. Apparently, the update installs the new Oreo recovery. All in all, can you go back to marshmallow if something goes wrong? Thanks for the friend answers.

Hi!

did this procedure, finally hu was shutting down properly.

But starting from today unit won't turn on...I've tried to reset, reconnect all cables but unit seems dead...haven't done anything, hu did turn off during a trip and now there's no way to turn it on.

Any idea what to do? Replace fuse?

update from 7.1 to 8.0

Hi Guys, I'm new on this forum...

I have a Dasaita PX3 with Android 7.1.2 with 2gb Ram and 16gb of ROM.

Some days ago, i read on aliexpress that they have produce a new unit with android 8.0, i'd like to know if it's possible to install this rom on my unit.. if yes can you please tell me wich one update i need to download?

Thanks a lot

Hope there's a solution
[MTCD Android Head Units General] typos1:
No, so far 8.0 has only been released for RK3368/PX5 units.

Can we use this other upgrade in HA unit or only mcu is adaptable to other units?
[MTCD Android Head Units General] typos1:
You can update to Oreo on ANY RK3368/PX5 MTCD/E unit.

Correct, only that it is MTCD/E and has an RK3368/PX5 processor.

hi,

For the MCU, i am on 2.59 now. which is under MTCD.

I planned to update to PX5 6.0 UPDATE HA (20180201)

do i need to update the MCU to latest MCU 2.75? but that is under MTCE.

Is there a difference?

thank you!
[MTCD Android Head Units General] typos1:
MTCE is a software update for MTCD - ALL MTCD units can be flashed with later MTCE MCUs (as long as theyre from the same manufacturer).

Its generally a good idea to update your MCU to the latest version you can find whether you update your ROM or not.

Hi thank you for the advice.

Hi

I have HA px5 MTCE with latest Oreo from Dasaita.

Just for try I replaced my firmware with GS version (20180118) which works alo good, and theres also split screen working correct.

I keeps MCU (MTCE_HA_V2.75_1)

I would like to go backto stock firmware, but As I see, here is only link to donwload PX5_8.0_hct3_1_ota_20170108 version, which is pretty old and with mising some widgets in lanucher

this version was on my device originally:

px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20180118.210918 test-keys

where can I get original firmware?
[MTCD Android Head Units General] PekeMM:
I'm bit reluctant to do a upgrade due the GS MCU and would not like to take a chance to brick due the flashing GS firmware to HA MM 6.0.1 unit, unless I'm 100% certain I can unbrick. (Device I have is in Attached pic Board should be v8.0 due the 4/32 board)

I'm guessing that Hotaudio will release new firmware after they get back from holidays.
[MTCD Android Head Units General] nobody7799:
Do you have link for rockchip rk3388-userdebug?

And wich are the laste rom

Thanks
[MTCD Android Head Units General] typos1:
Why are you reluctant to upgrade due to the MCU ? - You can flash any RK3368/PX5 ROM you like, you dont need to worry about the MCU.
[MTCD Android Head Units General] PekeMM:
I Wonder wouldn't soft brick also erase MCU also? Before I do anything I must be certain that I can enter Recovery 100% of times and for that I need to have it on my desk. For now I'm not willing to disassemble dashboard on -20^C outside (-11^C inside the car).

Also I've talked today with Dasaita and he confirmed that he told HCT to make Universal UI like GS one in new Oreo Firmware :) I also told him about issues with BT MD725 Module not working at all on Oreo.

In addition I also made big progress with iGO NextGen (iGO_PAL version) that now boots within 4-6s fully. What a difference to stock one. So there should be HA Firmware update very soon.
[MTCD Android Head Units General] typos1:
No a soft brick wont erase the MCU.

The MCU and ROM are separate, you can flash them separately and flash any ROM without worrying about the MCU. The only exception would be a very new ROM with a very old MCU.

Hi, I am not new to xda forum, I had to re-register due to missing email address!

I have purchased a 10.2” dasaita 8 core/4gb ram/32 gig shipped with Android 8 for my 2013 Jeep wrangler. I am trying to find the updates for this unit. It came with:

MCU: MTCE_HA_V2.75_1

ROM: px5-userdebug 8.0.0 OPR5. 170623.007 eng.htc.20180122. 155617 test-keys

1) Is this the correct thread for updates for my unit? (title says 2G ram, I have 4g ram)

2) is there a way to back up my current software? Just in case something goes wrong with the update, I would like to have the original ROM and MCU to go back too. I don’t see them listed on the 1st page.

3: What is the difference between the 3 android 8 images? I think mine shipped with the “gold” version that has the side dock which is annoying. I would like to try something that utilizes the entire screen... Which one should I use?

4) does anyone know the actual model number and brand of my unit?

Thank you

Re. MD725 Bluetooth not working for some on Oreo 8:

The latest [20180305] update is missing [system/bin/sdsdk] Adding this back in might solve the issue of MD725 Bluetooth not working for some people (MD725 Type = 2)

Update: Latest [20180305] PX5 Oreo Update contains [/bin/gocsdk] but not [/bin/sdsdk]

Explains why [MD725] type="1" works = GOCSDK but [MD725] type="2" doesnt =sdsdk.

These are called from BOOT - init.hct.rc:

on property:bt.md725.type=1

start gocsdk

service gocsdk /system/bin/gocsdk

class main

user root

group root

disabled

seclabel	u:r:shell:s0

on property:bt.md725.type=2

start sdsdk

service sdsdk /system/bin/sdsdk

class main

user root

group root

disabled

seclabel	u:r:shell:s0

Can you please supply an updated Oreo 8 containing this needed system file or provide the appropriate [sdsdk]?

For same date the Roms are identical except for the UI. Hct is the developer and they release their own Rom.with their customizations...as well as they do for other manufacturers...just change some kind of UI appearance (launcher) or other (minimal) things.

If date is significant different...then some changes or bug fixes are involved....currently we don't have the latest log for changes

God, I almost hate to ask this..

First, my unit is a Dasaita Hot Audio, 8.0 4Gb 10.2 I a Jeep wrangler. I, as many others do, don't care for the look of the buttons that are always there on the left side.. Regardless of launcher. I emailed Mr. Quick @ hot audio and he informed me that the now have a "blue UI" update and sent me the file.

This morning, I was able to download the file to my computer and send the file to a thumb drive. I kind of assumed that once connected, I would get some prompts etc but it didn't do anything other than open a player. I see the file if I open it but when I select it says that it can't open. Ive gone through just about everything in the settings to see if something else would make it go..

Am I doing something wrong? If someone could give me a pointer, point me to a better place to post or whatever, I'd really appreciate it. Search brought me to this page.
