RK3066 does not power on (recovery works fine)

Yes, I know that this sounds illogical but... I had this issue several weeks ago. After a normal power off the unit does not power up again. I disconnected it for a few days and then it started again. After that I saw a new ROM version here, installed and used it for weeks without any problems. Today it happened again. I think it it something about pressing/turning a know while it starts. However.

The strange thing is that I can get into recovery by reset button + power on. The fan turns and and the recover menu appears. I even wiped data, etc. but even a reboot does not work (unit stayes quiet - no fan - like dead). Any ideas? Feels like it does not get a "start signal" from the car (though it beeps when I press the reset button or plug the main connector in). Does it need a signal from the can bus adapter to start?

Hi guys,

I'm going to buy MTCB unit to my skoda and I have a problem to decide which model should I pick.

Joying is offering two units with exactly the same specs but different android os version, kitkat based unit is almost 40% cheaper.

I'm nexus user for years so I know differences between these os's well, IMO on car radio is not that relevant. Are there any noticeable advantages of LP model which make it worth additional costs?

Kitkat model: JY-VN130

Lollipop model: JY-VL130

I know that kitkat can't be upgraaded to lollipop so this decision will be final. I've checked all recent post on XDA and didn't find answer so I count on Your help guys

best regards!

My system is currently on Android 5.1.1, could anyone tell me if this Rom work for me?

---------- Post added at 05:37 PM ---------- Previous post was at 05:07 PM ----------

Also my system shows MTCC, is this ok?
[MTCB Software Development] Oldpapa49:
That's a good question. It's a MTCC with 5.1 already. Do you put the 5.1 for Mtcb or 5.1 for Mtcb.

MTCC is supposed to be like mtcb.
[MTCB Software Development] elyl:
The GPS is accurate, it'll be your speedo which is wrong. Most speedometers overstate your speed so their margin of error doesn't cause you to break the speed limit. The GPS will be more accurate.

HI,

I'm using ROM: update _4_4_4_FUSE_800X480_RK3066_40_MAL_12_06_2016_FIX_R ADIO_MTCB

The Music icon, where does it pick songs from? from SD slot or GPS Slot?

I create a folder called "songs" in root SDcard and placed in GPS slot but when clicking on Music icon, no mp3 show or it's doesn't have any click to click to browser to the SD.

I had to JetAudio icon. I think that what it called.

Thanks.
[MTCB Software Development] Oldpapa49:
In the Music App, touch the screen and slide your finger towards the right. It should display usb/Sd card locations

Hi,

as i can't get any respose from Pumpkin or in he hardware section:

Does anybody know, if actual Pumpkin Devices have internal sensors as acceleration, proximity, light.......?

Torque Pro finds nothing on RQ 0176E but the ODB2 data, even diagostic tools like elixir show not one sensor on board. No acceleration, to temperature, no gyro, no compass - absolutly nothing. So the question is: Are there really no sensors or is there an issue with this ROM (Malaysk 4.4.4)

As i flashed a lot of images i' not absolutly sure, but i believe to remember that with the stock FW 5.1.1, elixir showed some sensors.

Thanks for help!

Michael
[MTCB Software Development] Oldpapa49:
As far as I know, nothing is in the pumpkin on mine.

Compass is from the GPS

I think some GPS software will do acceleration.

Thats about it.
[MTCB Software Development] MiLe-SB:
Thanks, but i hope you're wrong ;)

In the other case, as lateral aceleration is the most important data to me, i'll probably sell the pumpkin and try to build another solution - probably with a sony Z3 pad :rolleyes:
[MTCB Software Development] Furniss91:
I'm still waiting to find out if this can be used on android 5.1.1.

Could someone let me know? Thanks.
[MTCB Software Development] typos1:
There are no Pumpkin devices, Pumpkin are re sellers only, they sell units made by several MCTB manufacturers, Pumpkin "model numbers" mean nothing to anyone and besides, all units from all MCTB manufactures are pretty much the same inside, regardless of what number Pumpkin gives them (all this is in the wiki).

To find out what device you have go to settings/about device, the letters preceding the MCU will tell you what manufacturer makes your unit.

However, no MTCB devices has the sensors you require, you may be able to add them yourself though.
[MTCB Software Development] MiLe-SB:
Thanks for your advice!!

I checked the wiki before, but it could'nt answer my question.

My unit is a Model.Nr.: S07, MCU: MTCC-KLD6-V2.91, so one of the rare MTCC. Manufacturer should be Klyde for HuiFei for Pumpkin, but this does'nt help, as none of these sources offers a complete datasheet.

But if no MTCB device has these sensors wich are standard in most smartphones or tablets, probably the MTCC won't have neither.

As i don't have the skills to add the sensors (and probavbly i never will reach this level) it would be probably easier to choose a base more close to my needs, so a tablet will be first choice.

Best regards Michael
[MTCB Software Development] typos1:
You could probably add them via USB or something, it was mentioned in the original thread, maybe worth searching it.

I ve only heard of MTCC once before, earlier today and it was a mis-type, AFAIK there are only MTCB and MTCD, can you post a pic of your about screen ?

MTCB RK3066 Sound and beep switch to home/main menu

Hello,

Love the new Radio,Music and DVD app, my issue is with the sound processor and the constant switch to home/main menu.

I am not new to updating rock chip devices or car audio.

Sound issue:

Before new Firmware was able to set max volume 28 of 34

After new Firmware I can only set max volume to 24 of 34 and it does not sound good at 24, speakers are distorted (only great at low volume)

&

Constant home screen switch from any application I am currently in. I cannot be in an application or any screen long enough to find what i want to change before it auto switches to the home screen.

I have tried both Malaysk ROMs NEW on June 12, 2016 and NEW on May 22, 2016 with the same results. I activated the exposed with the settings on the gps sd card in the gps sd slot. Only updating the Firmware and not updating the MCU.

I have the Pumpkin 6.2

ebay.com/itm/Android-3G-WIFI-6-2-Double-2-DIN-Car-Radio-Stereo-DVD-Player-GPS-Navigation-Cam-/191931296135

800 x 480 RK3066 original Firmware was 5 22 2015
[MTCB Software Development] MiLe-SB:
Here we go :)

Shortly, i had a MTCB MCU on the unit wich did'nt work at all (proposed from pumpkin support). Then i tried with the MTCB 2.85 from the HuiFei Page witch worked generally, now i have again the stock MTCC 2.91 as shown in the pictures.

Perhaps the developpers made a writing error?
[MTCB Software Development] Oldpapa49:
MTCC is real.. It is like a MTCB type what I understand but with 5.1 I think as OS
[MTCB Software Development] typos1:
Right, you mean you flashed a different MCU to get MTCC or you have a new unit ?

No, MTCC may indeed be real, but MTCB and MTCD have 5.1.1, so does [MENTION=7653139]MiLe-SB[/MENTION]'s MTCC - being 5.1.1 has no bearing on the MCU type.

What ?? Your question does not make any sense - you can see that Malaysk has a 5.1.1 version.
[MTCB Software Development] MiLe-SB:
The unit came with the MCU (KLD6-MTCC 2.91) and ROM shown on the screenshots.

Due to a small problem, Pumpkin support provided me another MCU to flash wich bricked the unit so i had to enter the recovery screen by a USB keyboard. As this was the best i could do with this MCU, i even don't know what type and version it was.

As it took some time to get the originally delivered MCU from Pumpkin, i flashed MTCB 2.85 (sure about the MTCB, not exactly about 2.85) from the HuiFei ressources wich worked.

A few days later i got the original MCU MTCC 2.91 from Pumkin and flashed this. Works great with Malaysk 4.4.4 but not so great with Malaysk 5.1.1 due to some lagging and boot problems. With the stock 5.1.1, there was no lagging and no boot problem.

As i know really nothing about Android, this was a hard time for me ;)
[MTCB Software Development] typos1:
Thanks, so it seems we have a third type of MTC unit then.

The lagging is nothing to do with the MCU, its to do with the ROM.
[MTCB Software Development] MiLe-SB:
If someone wants to have this MCU KLD6-MTCC V2.91 to analyze differences or what else, let me know
[MTCB Software Development] typos1:
Yeah, I ll try.

I have a suspicion it may be an update for MTCB MCUs, partly because the version number is so high (you d expect it to start lower if it was a new type of unit - MTCD and MTCB units started with v1.XX) and partly because the MTCB MCU worked pretty well on your unit, just gotta decide how confident I am about that before I try it on an MTCB unit . . .
[MTCB Software Development] Oldpapa49:
Do not confuse MCU vs Firmware. MCU is usually tide to KLDX like KLD6 with a version like V2.89.

What you are flashing is the firmware.

Android versions 4.4 or 5.1 with in Man's is FUSE meaning it combines the 1 or 2 gig with the 16 gig like making you to add as many apps with less hassle of a limit. That's a simple explanation.

As far as MTCB, MTCC and MTCD.

The MTCB was with android 4.4.x and when the MTCD showed up, it was 5.1.

To me the MTCC is a MTCB with 5.1.

The vendors said mtcb can't go to 5.1

But I can be wrong.

But for sure, do not flash the MCU unless you have a copy of it. Vendors don't usually release that part.
[MTCB Software Development] typos1:
I m fully aware of how MTC units work, I have had several for 2 years.

Thanks for your input, but I am afraid you are completely wrong about numerous things and your knowledge is seriously lacking :

I am NOT confusing firmware with MCU, I am NOT flashing firmware, I am talking about flashing an MTCC MCU on a MTCB unit (although technically both MCU and Android ROMs can be called "firmware")

I am fully aware of FUSE and which ROMs have it - ONLY booroondook's custom ROM is FUSE, NO others are, including factory ROMs.

MTCB is available with 4.2.2, 4.4.2, 4.4.4 and 5.1.1.

MTCC IS NOT MTCB with 5.1.1 - 5.1.1 for MTCB units works with MTCB MCUs as has been established for months, as I have said, I suspect MTCC to be an update for MTCB MCUs.

The "vendors" are only sellers NOT factories and they usually talk rubbish as you have clearly proved by saying "The vendors said mtcb can't go to 5.1", see above post and check the forums for more info (specifically the thread "5.1.1 for MTCB units", the thread title says it all).

I have flsahed MCUs more times than I can remember over the last 2 years, your advice "do not flash the MCU unless you have a copy of it" is I am afraid also incorrect, you do not need a copy of your original MCU, an earlier or a later one will do or even a numbered one - after updating a KLD MTCB unit with a KLD non numbered MCU the radio app stopped working (no sound, common), no other non numbered KLD MCUs would make the radio work the solution was to flash a KLD6 MCU which fully restored the radio.

Oh and who the hell is "Man" ?

Good evening,

I tried to install the latest update for my rk3066, and a error occurred (The message just says "error"), and now it does't show the user interface anymore.

What i did was:

1) I have downloaded the last update (update_4_4_4_FUSE_1024X600_21_RK3066_MAL_12_06_2016_FIX_RADIO_MTCB.rar).

2) Extrated the file and copied file update.img to the root of an sd card.

3) I placed the sd card in the unit, then i went to Settings --> About --> System updates, the update was detect, and i use it.

4) The update have started, but an error occurred in the middle of the process.

I turn off the radio, and when i turn it on, i just see the logo on the screen and i can listen the music on the background, the unit responds to the steering wheel controls, but there is no user interface, i can't do anything.

I'm very worried right now, what can i do to recover the unit or install the ROM?

Please Help.
[MTCB Software Development] Oldpapa49:
Sorry was having dinner and typing on a phone keyboard and autocorrect hits.

Man which I missed was for Malasky.

Maybe I should say OS for android.

4.x, 5.x etc which is the update.img file.

I usually suggest to leave the MCU file alone for the one in the radio is for the radio.

Vendors vs manufacture yes. Wide statement and sorry.

Another part hereyes has a list of MCU'S and if your MCU is not listed and you end up with wrong one, then it could a bad day.

What I have seen MTCC is newer and seems under 5.1 mostly.

But I see a lot of posts where people have done something wrong, either wrong update on the wrong mtcX unit.

I always update the img files.

Carservice with SWC and Google Play Music

Hi guys,

I updated my system (RK3188 1024x600) from the March Version to the April Version and unfortunately lost the ability to control the Google Play Music App with my SWC. I do get the toasts of the carservice app but it seems that either it doesn't forward those commands to the app or I missed something I have to do after doing an update from one ROM Version the a newer one. I updated Xposed installer and also turned off and back on again all modules. Volume works fine on the SWC but can't rev/fwd/play/pause on play music. Any ideas?

Update:

Whoever has the same problem: Check if you have installed XposedMTC and chose Google Play Music as your default player there, too. It seemed that I lost it over the update and forgot about it. Don't forget to restart afterwards.
[MTCB Software Development] typos1:
Well, I flashed the MTCC MCU today and everything works fine on my MTCB unit !

Previously with factory L and your L ROM [MENTION=6041319]dsa8310[/MENTION], the radio app worked, but on Malaysk's and booroondook's ROM, the radio did not and even re-flashing the other versions of L didnt not bring the radio back. In the end I flashed a KLD6 MCU (my MCU was a non numbered KLD MCU). This restored the radio and verything worked, but the xposed app that made the radio app save radio presets did not.

With the MTCC MCU the Xposed module that saves radio presets now works !

So, my theory that MTCC units are MTCB units with an MCU update seems to be correct and seems to be supported by some people using MTCB ROMs on an MTCC units.

[MTCB Software Development] typos1:
Ok, well sometimes the radio stops working after a ROM update and updating or even downgrading the MCU can bring it back again, so its probably worth updating to a newer version if you can, or to an older one if not.

After of course, checking the antenna lead hasnt come out the back, the antenna is still getting power etc.

I completely agree with this idea to customize the trajectory lines. The coding for the same is already there in MTCBackview.apk.

Try several and try changing the tuner type in factory setting as well - often after an MCU update the settings change, so that would be a good thing to do before you test it. Make sure its on the correct type and hasnt changed, try them all if you cant remember what type it was on originally.

Yours just failed randomly, not after a reset, so I would also take the top off and check that the earth lead has not become disconnected, this has happened before.

You could check out Auto Guard if you need a black box. The second question you ask is really confusing. You mention the radio while calling someone and also maps? Not sure what you mean there. Does your unit have a dedicated hardware button for navigation that you could assign to your preferred mapping application?
[MTCB Software Development] ankerede:
so auto guard is capable of doing an auto start and record?

[MTCB Software Development] flieswithhawks:
I believe it will do as you are asking yes.

If your unit does not have a hardware button set to launch navigation, you could always set up a "gesture anywhere" based event to do so instead.
