That would be a great solution if my concerns with compatability could be addressed. hal9k talks about his ROMs being for MTCC and MTCD units fitted with Rockchip RK3188 processors and build numbers starting with RK3188. As you can see in the specs I posted, mine is an MTCE device with an ARM 53 processor, the Bluetooth/WiFi chip is MD725 (from 'Settings/Factory Settings') and the build number starts with HA.
Thank you for your reply.

I have downloaded (from links provided at the start of this thread) ROM images for V6.0 and 8.0. I will 'upgrade' to 6.0 using instructions posted in this thread, leaving 8.0 for the moment as this thread describes that upgrade as 'dangerous'. My hope is that the upgrade will at least give me 'Developer options' so that I can start a 'USB debug' mode and use pc.kingoroot or similar to root-access the device. Or maybe even open up the WiFi.

Youre getting very, very confused here, youve not read it properly - @Hal9k_ does not talk "about his ROMs being for MTCC and MTCD units" - MTCC units are software updated versions of MTCB its, he does not make any ROMs for MTCB/C units. What he says is that this ROM is a "further development of" his "Mod v2.x based on Android 7", which was for RK3188/PX3 units, ie he has made a ROM for RK3368/PX5 units just as he made a ROM for RK3188/PX3 units. MTCD and MTCE units are identical - MTCE is a software update for MTCD units - after MCU version around 2.00 MTCD was renamed MTCE. His ROM is fully compatible with your unit unless you have an MD725 version 2 BT module in which case BT wont work (the OEM Oreo devs did not update the driver), if you have MD75 version 1 it will work.

Upgrading to Oreo was ONLY "dangerous" before @Hal9k_ realised his ROM - he devised a foolproof, non dangerous way to do the update, so what you have read is out of date and now untrue, although what youre probably referring to is the usual disclaimer that youll find on any dev's thread about any update possibly bricking a device ie trying to flash the files youve downloaded already would be termed "dangerous" as would flashing anything or indeed attempting to root your device using an app like kingoroot. Most users on here use custom ROMs as the stock ones re very bad, there are 1000s oun 1000s of posts on here about it.

Using Kingoroot is a bit hit and miss, the stock ROM is rubbish, I d recommend flashing @Hal9k_'s ROM, its pre rooted, it may or may not solve the wifi issue, if it doesnt, at least youd have root access and a far better ROM.

Re: your first paragraph, I'm quoting from what is displayed on @hal9k's web site in english (what little there is) which I accessed by clicking on the reference which led to his profile on which the URL of his website is shown, how else was I supposed to get information given the reference? I tried a search within this thread for 'Hal9k' producing only other people's posts. This forum is NOT producing good search results when we (I) don't know the subject and don't know what I'm looking for. Over the last few days I've been working through the over-60 pages of posts in this thread and picking up a snippet of information here and there.
What happened to the updating of information in the first post in this thread? The currently valid information is scattered randomly through those 60 pages.
Where is the information on Hal9k's latest ROM? It's obvious I'm going to be searching for another week before I find it without help and a lot more snide, condescending references.

gifs of toyota touch 2 hybrid info

Good Morning.
I would like to know if there is any way to get the gifs from the hybrid information screen of the toyota auris, the battery and the different states of the engines, to put it in the Dasaita.
Thanks and best regards.

I found a new setting in the "other" page of my GS MCU v3.0:

"Three way calling" yes/no

Anyone knows what is it?

Hi Guys

I'm trying to use Graser's Dasaita Tool to register my OBDLink MX as my OBD module. @Graser

All the options are greyed out, especially the space where I need to enter 3. the names of your OBD adapter.You can specify several names separated by commas.

Is there any reason why this is greyed out, I'm using a Dasaita PX5 32GB+4GB Head Unit Android 8.0

:(

What changes have you noticed?

Not much really except the following;
USB devices are more stable and the DAB+ does not disconnect anymore.
The radio also doesn't freeze during boot, which is such a relieve..
The update to 3.00 has been made to support the PX5 board i recently installed.

It's now on android 6, and i have to install 8 but time is an issue.
I verified and i have the first gen of the wifi/bt card installed so it should be compatible.

I run a PX5 board with 2GB of memory, would it be enough to run android 8 smoothly?

Hi,
In the first post I see that the last version of MCU's GS is 2.78.
I know about the 2.94 (@page 60:https://forum.xda-developers.com/an...mtcd-px5-headunits-repository-t3619906/page60)
Why the 2.94 is not linked in the first page ?
There are new versions ? 3.00 ?

If I install the 2.94 i can rollback (downgrade) to the 2.78 ?

What happen if i install a wrong MCU ? There is a way to recovery the device ?

Thanks

      * Updated versions of Google-system applications (Market, Gmail, Voice Search, Voice Synthesizer)
      * The composition of preinstalled apps added to Adobe Reader, Terminal, Root Explorer, Titanium Backup
      * The composition of additional applications added Xposed Installer and ADBD Insecure
      * Added alternate application "Radio" (the staff of "Radio" has a "KSP" interface, alternative - "GS")
      * Three launcher (KSP interfaces, KGL, GS / MX) with an operational switch to any of them through the "Settings" -> "Home screen"
      * Added control icons (buttons, icons) state of the upper line (the "Options" -> "Display" -> "Status Bar"). By default, all of the icons included , but can be individually turned on and switched on again at any time
      * Redesigned "Options" -> "About your device": added information about the author of the assembly, as well as direct links for those wishing to reward financially
      * AOSP-enabled application "Contacts"
      * Added the ability to interactively change the screen density ( "Settings" -> "Display" -> "screen density")
      * Open the following items "Settings", "Data Transfer", "More / Ethernet", "For Developers"
      * Access to ADB console through the network (port 5555)

      * correcting defects in the assembly of the first embodiment EEPROM, doispravlenie Russian translation.
      * the introduction of support so-called "white list" - that is, applications and services (services), which will not be "killed" when leaving the radio to sleep. The most typical applications that require a "protection from killing" - is working in the background of the services associated with navigation, warnings about traffic conditions, etc. For example, "Antiradar Arrow" and "MapCam Info". Now, such an application can be stored in the "white list", and after the release of the radio sleep they will work. To implement this functionality is managed through the works of respected Graser , who wrote a wonderful utility PreferenceApp , a challenge which I built right into the "Settings" ( "Advanced Settings", select "White List")
      OTA2: V1.0.2 -> V1.0.3 (Required previous OTA)
      * added alternative application "Music" (from KLD firmware)
      * added the second alternative application "Radio" (in KLD EEPROM)
      * added "double" launcher (KLD of the firmware)
      * radically altered algorithms support the "white list" of applications that retain their efficiency when caring to sleep. For their work fervently thank (do not skimp on Desi) respected graser

    This thread is intended to collect all the information about MTCD PX5 Units:
    Roms (Stock & Custom)
    Launchers
    Mods
    Q&A Section

    ----------------------
    This Unit is an upgrade of the MTCD based on RK3188 Chipset.
    It has been released on late 2016 and it seems to be the MTCD advanced model, being an updated PX3 (2GB RAM - Andoird 7.0.1) the basic model for the MTCD family portfolio.

    The unit consists on two parts:
    • MCU board, which controls physical buttons and A/V inputs/outputs to/from the headunit. This board interacts with Android OS.
    • ANDROID part. The main Operating System.

    Both MCU and Android ROM interact together to achieve the functionality of the unit


    When an update is released two files are provided:
    • The Android ROM (update.img file) is currently based on Marshmallow 6.0.1 and it is common for all the MCTD PX5 Units from different manufacturers-
    • the MCU (dmcu.img) is specific for each manufacturer and it should never be updated with other manufacturer mcu update file (unpredicted response from physical buttons - or CAN bus responses, or bricking the unit)

    Manufacturers.
    The Manufacturer is identified by the XXX when consutling the device information [MTCD_XXX_Version]. Take into accout that you should always refer the MANUFACTURER name (not the seller) on the forums for help/assistance. Giving the name for the Seller does not give any information but confusion.

    e.g: MTCD_HA_1.93_1 (MTCD Unit with MCU for HOtAudio under 1.93_1 version)
    Known sellers & the respective manufacturers for MTCD PX5 are:

    • SELLER [Man. Acronym] (MANUFACTURER)
      ______________ _____________
    • Dasaita/HotAudio [HA] (Dasaita)
    • Erisin/Pumpkin [LM]
    • Erisin [KGL] (Kai Ge Le)
    • Xtrons [GS] (ShenZhen GESHI Electronics And Technology CO.,LTD.)
    • Witson [MX]
    • ????? [HLA] (Hualingan)
    • ????? [XRC]
    • ????? [HZC] (Shenzhen Hansong Electronics Co. Ltd.)
    • ????? [KSP] (Ka Si Pu ShenZhen)
    (this list will be updated according to users report new sellers/manufacturers)

    MTCD Unit Types
    All PX5 units are close the same. Only physical buttons or added functionalities by external CAN bus decoder (provided by the manufacturer) can differenciate them.

    • Xposed Module To overcome the OBD bluetooth limitation:
      Bluetooth OBD devices that name does not start with "OBD" does not communicate with the OBD app, as the app does not detect the OBD device and wants to open the Bluetooth connection.
      Fields:
      1. Class name in HCTBlueToothManager - by default, the class name for the AIC used in the firmware is specified.
      2. Method name in HCTBlueToothManager - by default, the class name for the AIC used in the firmware is specified.
      3. The names of your OBD adapters. You can specify multiple commas.

      In case of custom or non standard HCTBluetoothManager.apk, it is required that the user fills the Class Name and Method name

      Once done delete your OBD device from pairing, reboot and pair again. Now OBD apps will detect the device connected as Bluetooth OBD device and will not hang to try to open bluetooth.[/COLOR][/SIZE]
    • RDS Radio. ***XPOSED REQUIRED****
      Allows you to set the frequency of the current radio station in the notifications from status bar
      Fields:

    Reserved: Q&A
    1. I have a MTCD RK3188 unit. Can I use the firmware updates here published?
    No. All the stuff here published is for RK3368 (PX5) MTCD units. Only the MCU files could be used for your unit (if it is really a MTCD)
    2. My MCU is XXX and i can't find new updates from manufacturer for a long time. Can I update from other Brand MCU?
    Not all the MTCD MCUs are the same, but quite similar between them. There is a thread that is collecting all the MCU cross compatibility based on user experiences.
    https://forum.xda-developers.com/an.../mtcd-verified-cross-compatible-mcus-t3624724
    3. How Do I enter into recovery menu?
    Depending on the HeadUnit, the entering into recovery process could vary.
    • Reset Button Procedure (You need a needle to access that button inside the Reset hole)
      Applicable to:

      • [*] HeadUnits with no physical buttons on Headunit (just capacitive buttons) [Brands: Dasaita]
      1. Press Reset and hold until button light blinks (15-20secs)
      2. Release Reset and press again. Hold it until you see the Marshmallow logo
      3. Release Reset and wait for the Recovery menu to appear

      [*] Power Button Procedure [Brands: Dasaita]
      Applicable to:

      • [*] HeadUnits with physical power button on Headunit [Brands: Dasaita]
      [*]When none of the above procedures worked:
      1. Disconnected all power from the unit... ACC & BAT disconnected
      2. Prepared 12V power supply with on negative and two positive connectors
      3. Connected negative to GND & one positive to BAT
      4. Connected USB keyboard
      5. Press right ALT (ALT GR on some keyboards) and PrintScreen
      6. Connected the other positive lead to ACC (unit does not work if both BAT and ACC are not connected)
      6a. Start pressing repeatedly on E (not holding E pressed, but press...release... press... release..... rapidly)
      7. The boot logo shows (MarshMallow...etc) and after a few seconds the unit reboots itself
      8. Release right CTRL & PrintScreen and continue to repeatedly press on E.
      9. The Recovery shows on screen.
    4. I have a complete Bricked Unit with a continuous loop. What can I do?
    First of all, you have to try to reload the firmware into the unit. As you are not loaded into Android system, you must reload the firmware by using the recovery menu. To enter into recovery menu read the FAQ#3.
    Most of the times, reloading the Android firmware solve the issue. Try with different firmwares if you can't succeed at first time. When, even having tried to update your firmware from recovery, but it did not succeed, you probably have corrupted your NAND. In that case a more complex solution is available (desoldering/soldering is required) to come the unit back to life. Thanks @marchnz for the detailed description on the following thread:
    https://forum.xda-developers.com/an...tions-development/px5-stuck-bootloop-t3635412
    5. I notice echo on my Bluetooth Calls
    Echo has been reported on severla Brands/Models for PX5 firmwares. The echo is not instantaneous and it appears after some minutes of conversation. Currently @f1x is developing a solution based on tunning the Bluetooth drivers. You can follow the solution in this thread:
    https://forum.xda-developers.com/an...elopment/px5-solution-bluetooth-echo-t3638779
    6. My HeaadUnit never shuts off and, even several days, after switching engine on the Headunit starts in a few secons....Can I kill my car battery?
    These units are designed to enter into deep sleep state detecting ACC off, in order to avoid each time you connect the car, you had to wait a full cold boot (20secs) and they just wake up in 2seconds. During This sleep state, the Headunit consumes a small current (just 100-150mA). Such current can't drain your battery.
    Some manufacturers (like Dasaita (HA)) have implemented a menu in which, apart of Auto-Sleep you select at which time you want to HeadUnit shuts off completely, useful for long car unused periods.
    7. My apps are killed during Sleep and they don't start again after waking up
    These HeadUnits kills background processes (except specific ones) during deep sleep state (see Q&A#6). The killing process is managed by MTCManager.apk file. A developer (@graser) has been released a tool that is based on adding apps/services to a whitelist to pevent the unit killed them during sleep. You need root & Xposed Framework
    8. Google Maps Hangs when starting a route
    It has been identified that Google Maps hangs constantly. One of the reasons provided is due to corrupt data after not properly exiting Maps application, which occurs automatically bu the ROM when entering into sleep.
    Three Solutions have been reported:
    8.1 -> Install 9.46.2 version --> https://www.apkmirror.com/apk/googl...ation-transit-9-46-2-11-android-apk-download/
    8.2 -> Add Google Maps to the Whitelist on Graser's app (see FAQ#7) [Root & Xposed required]
    8.3 --> Clear Maps Cache before starting app (after each sleep). You can use this apk: https://forum.xda-developers.com/attachment.php?attachmentid=4295635&d=1507415766
    9. I cant find MTCDs MCU updates, but MTCE. Can I update a MTCE over a MTCD?
    HCT developers, starting from MCU version 2.65, has been renamed the MCTD as MTCE. It is reported to be a major software update and it is fully compatible with MTCD MCU. Therefore, you can upgrade to MTCE from MTCD safely.
    10.Can I replace Google Now by Google Assistant?
    Yes you can. extracted from https://forum.xda-developers.com/an...ment/px5-to-install-google-assistant-t3629660. Thanks @apollo1976
    1) change the resolution using the "Resolution Changer Pro" app (https://apkpure.com/resolution-changer-pro/com.nexter.miniscaler). I set the 1280x800 resolution, with DPI 280. Other user reported that thw working resolution is 1365x800
    2) Reboot the system
    3) Installed the Google Assistant apk (https://www.apkmirror.com/apk/googl...assistant-0-1-174051423-android-apk-download/)
    11.How can I root my unit?
    PX5 devices under MM can be rooted easily by means of using kingoroot app (not kingroot).
    http://es.kingoapp.com/
    When installing a Warning message will appear, but you can continue the installation.
    You need internet connection for kingoroot during root process.
    After getting root privileges, remove kingoroot and install SuperSU
