Hello, I can not get my Erisin Es3093p update and I can not get into the recovery either. The update menu tells me no image update file. I remove all SD and USB minus 1 and formatted in fat32. It is android 5.1.1 with MTCD_LM and rk3188. What I can do??
[MTCD Software Development] typos1:
Read the entire thread, carefully, its clear from your post that you havent paid full attention to the details, I really dont want to type out again what I and [MENTION=5092263]Hal9k_[/MENTION] have already typed several times.
[MTCD Software Development] saltofx_v:
everything perfect with the rom. Is there any possibility to have volume adjustement according to the vehicle speed? i had this at my old ford fiesta.
[MTCD Software Development] inscriber:
here you are.
[MTCD Software Development] typos1:
It clearly says "PX3" in one of those apps PX3 = RK3188, also in settings/about device it says its quad core - "x4", RK3066 is dual core.

You have a 2Gb RAM Nougat MTCD/E unit, ie RX3/RK318.
[MTCD Software Development] inscriber:
so CPU Z mistake? I apologize and will delete my first post so no one will flash this on rk3066
[MTCD Software Development] typos1:
Its ok, dont worry, its best to leave it how it is, dont delete, then everything that was said can be seen.
[MTCD Software Development] Pattond:
I have a MTCD RK3188 with 1G. I have failed at moving from 5.1.1 a couple of times, and right now I am stuck at the 5.1.1 recovery screen after trying to roll back to Hak9K v1.3. After driving to work with my system stuck on the Lolipop screen (SD card was out),

I figured out that I was missing that I needed 2 media devices, one on the SD card to allow the boot and a second for the ROM. And the recommendation is to boot from the SD Card in the GPS slot and put the ROM on a USB and upgrade from there. My challenge is that my unit does not have a traditional USB port that is accessible without removing the system, but it does have a Mini USB and a second SD card slot.

Since a USBMini adapter is locally unobtainable, can I take a MiniUSB to USB A cable, then get a USB female to female adapter and put the Flash card there? Otherwise is there a way for the system to recognize the 2nd SD card for the ROM?

[IMG="Headunit"]https://i.imgur.com/kWrP4iM.jpg[/IMG]
[MTCD Software Development] typos1:
Once the unit starts to boot to recovery from the sdcard, eject it as soon as "Lollipop" appears on screen, then insert another sdcard into the GPS slot with the ROM on and flash it from the GPS slot, you dont need to do it from USB.
[MTCD Software Development] masri1987:
so i'm confused for a min , i got a pop up saying that version 2.3 is out but i barely got the pop up for it, was it really released june 25th? lol
[MTCD Software Development] Pattond:
Thanks, I got 5.1.1 running again (nice upgrade from v 1.1), will try to move to 7.1.2 again tonight
[MTCD Software Development] Hal9k_:
Many users note a significant improvement in performance when using microG.

For maximum performance on the your HU, I recommend using Mod 1.3 with microG. I myself use microG in a test environment with the old core board.

Hard to tell.

All the necessary actions are described in the instructions.

Is the HU booting from the boot card in the recovery ?

Is the HU booting in the normal mode ?

Unfortunately, this logic is not available from Android. Android can only turn AF on or off.

Moreover, I doubt that it is available from the MCU. It can hide in the radio IC module.

It will be in the next version.

This pop-up message informs you that you are using the old version 2.2, whereas for almost a month version 2.3 with new cool features is available. :D

And very soon there will be an update 2.3.1 ;)
[MTCD Software Development] raptor_demon:
All the necessary actions are described in the instructions. - Yes, but i assume i must be making a mistake

Is the HU booting from the boot card in the recovery ? No

Is the HU booting in the normal mode ? Yes

Rds alternative frequency

Hal9k

Thank for your answer, unfortunately there is no chance to solve rds problem. Question is am I only one with this problem? Anyone else occurring this? :confused:

Cheers

[MTCD Software Development] Hal9k_:
Then try to create a new bootable SD card and try installing the firmware again.
[MTCD Software Development] LordAnpu:
Unfortunately it is problem with HU designed in China. I think I read somewhere that in China they don't use AF.

Few months ago my unit change to another radio station instead alternative frequency, but now after updating the MCU (I do not remember which version it was), my device start changing to the appropriate alternative frequency, but the device does not store it in memory and after restarting HU the radio station is set to original frequency. In my region one of my favorite station has 3 different frequencies in 100km radius, so that is problem. I don't found any solution, and I don't think there is any, at least until they start putting some good radio tuners like Pioneer or other manufacturer do.

---------- Post added at 07:39 PM ---------- Previous post was at 07:33 PM ----------

I hope that version 2.3.1 will have a menu allowing you to choose which sources toggle the mode button, or at least 2.4 will have :)
[MTCD Software Development] typos1:
The problem is app or MCU related, it coud easily be fixed by someone who knows what theyre doing, in fact someone did it on the closely realted MTCB/C units a few years back.

But it sounds like its now working on your unit - why would it store the different frequency ? The idea is that it changes to another frequency of the same station if its stronger than the one currently being used, not to overwrite existing presets. Store the stronger frequency if thats the one you want.

Pioneer and other manufacturers use the same amp and radio chipsets as these units, its not the hardware, its the software.
[MTCD Software Development] LordAnpu:
I checked and after update to MCU 2.65 and now 2.88, AF works (I think all MCUs that change name from MTCD to MTCE).

On Sony, Blaupunkt and Pioneer I had before, alternative frequencies was restored after shutdown. Especially Pioneer had excellent radio tuner, and its reception was much better than this HU has, so I don't think they use same hardware.

If radio app would stored as default new stronger frequency, the problem would be solved. But for now, I manually save new frequency on different memory position if I know I must shutdown car.
[MTCD Software Development] mariuscov:
Hello

I'm doing like you explain in post. The HU show me updating system but after a few minutes the screen ibecame black and nothing happens.

Help me!

What I'm doing wrong?

---------- Post added at 11:59 AM ---------- Previous post was at 11:46 AM ----------

I have done exactly as you described in post. I have EONON GA2169 MTCD RK 3188 with Android 5.1.1

It's starts and after appears on the screen updating system, that least few minutes, the screen turn black.

What I do wrong?

What should I do?

Please help me!
[MTCD Software Development] typos1:
Lots of big name brands use the same or similar chips, it is fact, but as I said the SOFTWARE is different - hardware can work differently with different software.

This is when using the bootable sdcard or flashing the ROM ?
[MTCD Software Development] mariuscov:
I use the bootable SD card to enter the recovery, after the picture with nougat appears I switched the SD card with that where I putted the image.

It starts installation and after that black screen

Maybe I have to wait more than 10 minutes?
[MTCD Software Development] typos1:
It can take a while to install.
[MTCD Software Development] R4m80:
Thanks. That worked. Maybe the description in the Op should be amended to reflect this.
[MTCD Software Development] typos1:
Well, [MENTION=5092263]Hal9k_[/MENTION] says he can do it without removing the card, but every time I ve done it it only works if I remove the card as soon as Lollipop appears on the screen.
[MTCD Software Development] alexgabi3007:
Can someone help me find out what the CANBUS protocol is for my Audi A4 B7 2008 in North America? Steering keys work w/o one but I don't have vehicle info. I don't know which protocol of the numerous ones is the right one for me.
[MTCD Software Development] typos1:
These units dont generally give vehicle info for Audis, you would have to write an app for it yourself.
[MTCD Software Development] alexgabi3007:
Ok, but how come the factory CANBUS options give me a few different protocols on simple, bagoo, hiworld for my A4.

Anyone got it working for their B7? Which one worked?
[MTCD Software Development] typos1:
Theyre not protocols, theyre CAN Bus dox manufacturers.

Only a few car types have an app that appears ("Car settings" app, "Vehicle" app, "Control Settings" app), Vws, BMWs and Opels usually do, for some reason none of the Audi units I ve seen have one, which is strange considering how closely related to VWs some of them are (A1 is Polo based, A3 and TT are Golf based).
[MTCD Software Development] alexgabi3007:
I'll go ahead and remove my unit to uncover the different wires since it was also wrongly wired for the rear amp and see if I can find any info about my canbus decoder info and I'll get back here early this week.
[MTCD Software Development] R4m80:

[MTCD Software Development] alexgabi3007:
I've went ahead and looked at the wiring harness and the quadlock for some information about the Canbus. It seems like CAN-HI and CAN-LO go to the quadlock and to the decoder, but only CAN-RX is received to the HU. Could this be what causes the canbus to work only w/ my steering wheel? There isn't any pin or cable hooked up to CAN-TX so the signal is "lost" at the decoder. Anyone have a wiring diagram for my decoder or a general one? I'll attach some photos.

Hi, thanks for this mod.

Just posting for reference, that it works on a Corehan CDUN-ZZH-VW-A. The device itself is of questionable quality, but this mod made it a little more tolerable. Thanks.
[MTCD Software Development] nomorebigideas:
Sorry to hijack the thread - was wondering if anyone could help...

Does anyone know how to flash / unbrick the RKPX3 units (mine is for BMW in particular)? I've only got a USB connection to it and mine, not an SD.

Without warning it's loading up on the Android side with 'No Signal' and nothing else. The BMW OEM side looks like it's EGA GFX (for anyone of a certain age). Have checked cables etc, all are connected.

I have a hard reset button if that's any good. Have heard about trying to get the bootloader responsive by using a USB keyboard and 'alt' + 'prtscn' + 'i' trick...

Headover to the first page

· How to install this firmware instead ofAndroid 5.1.1

Download the attached archive with the _Firmware_Tool utility and unpack it.

Prepare a micro SD card for 2-4-8 Gb. It will be

completely 0verwritten

Prepare USB flash drive with the same firmware.

Insert the card into the PC card reader and run

SD_Firmware_Tool. Exe as Administrator.

Choose the removable disk.

Clear the"Upgrade Firmware"check box.

It's important!

Press the"Firmware"button and select

nupdate. Img file.

Press the"Create"button and wait for the

Drocess to finish.

Insert this card into the"GPS"slot on the radio.

Insert the USB flash drive with the same

firmware into the USB slot on the radio.

Hard reboot or turn off and turn on the

power of the radio.

The radio will boot the recovery from Android 7

from the card and will go to the menu.

Select"Apply system image from SD card or

USB">"From usb storage"

Wait for the flashing process to finish.

Then select"Wipe data/factory reset"

Then"Reboot system now"

Radio will ask you to remove the SD card

Remove that.

the radio will boot android 7

[MTCD Software Development] drizzor:
[MENTION=6579214]imran a[/MENTION]lready got Android 7 with Firmware 2.2 installed. I still need the way you quoted to Upgrade to 2.3?
[MTCD Software Development] imran0487:
Have you tried the below steps

How to install the firmware ?

Extract the nupdate.img file from the archive to the root of the USB flash drive or SD card. It must be formatted in FAT32.

Take out all the other flash drives, SD cards, modems and other devices from the radio jacks.

Insert the USB flash drive into the USB connector of the radio. It is desirable to use the connector in which it is defined as USB1 (can be seen, for example, in the player).

Or SD-card - in the GPS slot.

The radio will prompt "Firmware Updating".

Click "Install".
[MTCD Software Development] drizzor:
Did that. It tries to Install but ends up on a blackscreen saying "failure"
[MTCD Software Development] imran0487:
You should try the sd and usb method with sd firmware tool..that should work..
[MTCD Software Development] Hal9k_:
Also, this may mean an error when writing the firmware image to internal memory.

Take another flash drive and unpack the nupdate.img file to it again.

Check filesystem on the flash drive.
[MTCD Software Development] Hal9k_:
not yet ;)
[MTCD Software Development] imran0487:
Thanks mate for 7.1.2 love this rom..ill upgrade my px3 to px5 so was wondering...will come back later to check if you have something for px5:good:
[MTCD Software Development] drizzor:
Tried to update via the Popup and the Recovery modes with a USB stick. Didnt work. Yesterday i copied the nupdate.img to a SD Card and installed it via recovery mode. Works like a charm, thx Hal9k!
[MTCD Software Development] 666cin:

[MTCD Software Development] BlinkyTrojan:
Is it possible to increase the delay/threshold of "Application not responding" (ANR) message or speed up the startup?

Is malaysk or hal9k rom better?
[MTCD Software Development] meazz1:
Wrong question to ask here.

You may wanna try both to see which one you prefer.

I never tried malysk rom. I'm very happy with Hal9k's rom. No lag or reboots. It just work for me.
[MTCD Software Development] Yeahmään:
I tried both but older versions. I installed hal9k latest version today. But it feels same. Sometimes slow, sometimes installing apps take for ever. I have a px3 device with 2 GB ram
[MTCD Software Development] BlinkyTrojan:
I personally think that Hal9k's ROM is much cleaner but some optimization should be made on older RK3188.

This is also true for my older RK3188 unit (refer to quote above), with the annoying "Waze isn't responding" on every startup. Hopfully the next version can tune the respond time.
[MTCD Software Development] Yeahmään:
How can I change to microg and will there be problems with apps?will it be a little bit faster?
[MTCD Software Development] Hoppengeist:
Within the Mod settings app. It will be faster. It will create problems with apps that need a google login or in app purchases under some circumstances. It will als require you to cache wipe for each update of the firmware (was the case for me)
[MTCD Software Development] mariuscov:
I installed this ROM and after I solve the issue with screen resolution everything works fine. One single issue remain unsolved. The DVR app doesn't work: I see de image but when I touch the record button in 2 seconds the app closed. What should I do to solve this?
[MTCD Software Development] HamzaMehyar:
Might be a stupid question, but i currently have malaysk 5.11 rom and im upgrading to this one, my unit has an sd card and a usb port, do i really need to use the sd card? i currently do not have an sd card reader, but i could boot into recovery because its rooted, is the sd card used only to boot into recovery or is it needed to install the rom?

Thanks a lot
[MTCD Software Development] Hal9k_:
[MENTION=8611603]HamzaMehyar[/MENTION] you must boot your HU from the SD card if you upgrading from 5.1 OS.
[MTCD Software Development] HamzaMehyar:
Thank you for your reply, I have tried I have tried upgrading directly because I'm an arrogant person but I got an error, sorry and thank you.

I'll prepare an SD card then!
[MTCD Software Development] Overmann:
A little thing to note

I finally got a PX3 2GB coreboard, to upgrade my 1GB. Since the PX5 doesn't wifi or bluetooth, I figured this is my only option without breaking the bank.

Initially, it didn't work either. However, I flashed this ROM, and then I reflashed the MCU to the new SP one up on top of the forum, and that did it. Now I have wifi and bluetooth on the MD725 and it has a 2GB PX3, for all of the speed.
[MTCD Software Development] Drezki:
I just installed the ROM and Bluetooth (A2DP) and Wheel Controls are not working. How can I figure out which options to select under factory settings to fix this?

My HU is an EONON GA8198 PX3 2GB 7.1.2.

Currently when I open Bluetooth I get empty fields for name and pin. If I set the name and pin, I still cant find it on my phone.

As for the wheel keys, I just see a "Save" and "Reset" button and the rest of the page is empty. I've read in other posts that I might not be able to adjust the wheel controls from here. Where can I go to adjust these settings?

[MTCD Software Development] mosquitogang201:
First off, this ROM is awesome. It has finally made my head unit worth using.

I have one remaining quirk to solve. A2DP volume is too quiet. If I turn the head unit to maximum volume, connect my phone to bluetooth/A2DP, and use the volume control on my phone, I have noticed when increasing volume that I get to about half way, and although I continue to increase volume, the output from the head unit does not increase further. It's as if there's a volume limiter for A2DP on the head unit. This effect doesn't happen on another bluetooth speaker I have... that one continues to get louder and does not limit the volume.

Is there any way to fix this to unlock a full volume range for A2DP? I don't mind tinkering with system files, just not sure where to look.
