Latest download not working for RK3066 800x600

Hey,

is there any suggestion what to do when the latest download link error message is:

Firmware Assembly Tool for KLD_20161226_mod_root_boo_2017-03-09

~~ Sorry: RK3066 CPU does not support in this firmware ~~

Any idea?

thank you
[MTCB Software Development] typos1:
Yes - you CANNOT use the 5.1 version of this firmware on your unit because it is dual core and this ROM is for quad core units only because only quad core units support 5.1. You can use an older, 4.4.4 version though.
[MTCB Software Development] bleee:
Thank you! I undestand this now, but I think its misleading in the topic, as it is stated there that its also for RK3066. But again, thank you to clearify this issue. Then I have to ask, what is the latest booroondook version with fuse on RK3066? I cant find anything. Id be happy to go with a 4.4.4. booroondook on my unit.
[MTCB Software Development] typos1:
If you read the thread your ll see that there was a 4.4.4 version first, then a 5.1 version was released, but this was only for quadcore units as I said.

Also your ll need to read the thread to find the download link for the latest version of 4.4.4 for dual core units.
[MTCB Software Development] jonnymacs:
In case you haven't located it yet Post #677 in this thread I shared a link to 4.4.4.

Problem with head unit Fuse

Hello,

i have a head unit rk3066 with the touch screen no buttons, after a few months fm radio part stops working no pickup of stations and no sound static or play station music and no search of stations there is nothing to receive.

i have this problem with a stock rom also, to fix this fm problem a flash the stock rom and fm radio works for a few months.

last week same and the stock rom didnt fix it so i try fus rom 1.00 better head unit and radio fm oke all stations etc

just for 1 day fm radio dead also on the fuse 1.01 .

i tryed all mcu 2.16 2.58 2.73 and 2.86 nothing. is the fm radio a board in radio of a chip? but the fuse is a great piece of software i have now 6.5 gb in the unit instead of the 1 gb stock

is there anybody for to fix this now,--- i have now (L0L) a very expensive mp3 player in car.

Thanks in advange

Ron
[MTCB Software Development] typos1:
Did you check al the connections to the radio module ? Sometimes the earth comes off, also, there are several radio tuner types in factory settings, have you tried them all ?
[MTCB Software Development] ronny1960:
well i have not puth the radio out of car and opened it, now i am thinking maybe this ground cable did come loss i follow the mtcb tread for a while and saw the pic of lose ground .

i thought much deeper software or chip,

i will saturday get unit out and open it to see.

Thanks for response i will get back when i opened it
[MTCB Software Development] ronny1960:
RK3066 No FM radio

@ typos1

Opened the head unit and no ground wire,

inside is a casing soldered to another casing

So how to go further open the 2 boxes or take board out completly?

or leave it as it is and buy usb dab+ module with a rtl driver?

i saw one at ebay for about 24 euro

because soldering the antenna connecter or the other part out i maybe do more damage to the board i think

ron

I cant attach the inside pic of unit if you can go to link below

http://imgur.com/a/BFXae
[MTCB Software Development] typos1:
Theres nothing visibly disconnected ?
[MTCB Software Development] ronny1960:
Nope the 2 aluminum rectangle are the only visible items the left one is soldered (ground) to the antenna connector.

To see more i have solder them out and open them. but i think thats not a good idea

ron
[MTCB Software Development] m00n61:
Most likely your problem is due to the unit losing radio chip info at boot. Enter factory settings (use password 126) and try to change the radio to a different one.
[MTCB Software Development] typos1:
Right, if nothings visibly wrong then leave it.

I ve assumed you are using the correct radio tuner setting in factory settigns, as [MENTION=834020]m00n61[/MENTION] says, try all of the ones in factory settings and see if the problem goes.
[MTCB Software Development] ronny1960:
i tryed all ..TDA7706 is standard will try it again

is there for the fuse rom maybe a script that leaver the radio at the TDA7706 setting.

the strange thing is that all fm stations where there and 9 ours later none (with installing fuse)

i installed even mcu 1.16 now and then it says music stops goes out i press music and start again normally i will install mcu 2.86 and return to TDA 7706

i will get back with info

i thank everybody for support.

it a great thing if every thing works and with the fuse its even better

Ron
[MTCB Software Development] typos1:
Theres nothing for the ROM re the radio because its MCU controlled.

What unit do you have / Most KLDs can be updated to the MTCC KLD v2.98 MCU which saves stations.
[MTCB Software Development] ronny1960:
I have the JY unit and i think KLD can not be installed or is there a JY 2.98

i have the JY 2.73 normally installed

Pic of side of unit

http://imgur.com/a/UoCUu
[MTCB Software Development] typos1:
If you have JY you cannot install KLD MCU. XposedMTC will save radio stations though.
[MTCB Software Development] ronny1960:
well the stations where all there only no sound

Thanks for the suggestions i wil try them all
[MTCB Software Development] typos1:
Right I see, thats not your problem then, but still knowing how to save them will be useful for you. Have you tried all radio settings yet ?
[MTCB Software Development] ronny1960:
Nope will doe this tommorow unit still not together,few bolts to screw in

Question: The first fuse Rom 1.00 does not have a build in MCU? will a install the 1.00 ROM instead of ROM 1.01

And MCU 2.73 or 2.86? higher number of mcu maybe not better

Second what do you mean with exposedMTC i have not fully used the rom because i have the FM trouble.

Is there explanation about the exposed MTC (manual) googled but did not find briefly something.

Ron
[MTCB Software Development] typos1:
ROMs and MCUs are entirely separate - no ROMs have "built in MCUs".

XposedMTC is an app that will make your unit save radio stations among other things., you need to install the Xposed framework and root your unit.
[MTCB Software Development] warata:
Today I received OTAupdate(ROM:Ver161226)

Anyone know what features were added, or what was fixed?
[MTCB Software Development] ronny1960:
Okay i have build unit back in car

Put MCU 2.72 back changeed the radio band from something back to mid western regio applyed it

application of radio TDA 7786 alpply it

and reboot unit all stations are there sound okay. then i turned ignition key off, i wait more as 30 sec everything gone no stations and no sound well the frequenty of stations is on the buttons but no radio noise.

have this unit more then a year never have problem with power car can stay on fore long time and car starts also in the morning

do the fuse ask for a differnt wire for power to keep the staions there its a factory plug in the car and connets normally to wire plug of unit.

its like shutting down power the problem appears?

it looks like when sutting down power for unit more then 30 sec something is erased in unit maybe i must switch wires in plug to get a constant power but this is strange because from first day getting unit in car it whas good

Ron
[MTCB Software Development] typos1:
Its not a cutting power problem, I dont think, it seems to be something else, what I dont know. Have you tried a previous version of the FUSE ROM at all ?
[MTCB Software Development] ronny1960:
Yes

i tryed first the fuse 1.00 rom maker then the problem ocured with the stations, then i flashed it to fuse 1.01 same problem (with the stock rom only after several months)

i have the stock rom this will probely work but no 6gb disk space and after 6 months this same problem ocure with the stations and stock rom

its a flaw in unit but with one.

can i flash stock rom back to unit or will fuse give problem

i am a painter of houses etc ,i have my own shop and i know a (very) little of this matter, i am so busy i can mostly only fix things in weekend.

ron
[MTCB Software Development] typos1:
Its very strange, I ve not heard of it before. Have you tried [MENTION=6041319]dsa8310[/MENTION]'s ROM ? Its not FUSE but it has 3GB for apps.
[MTCB Software Development] ronny1960:
No i haved heard of it i did not look at this site for over half year.

if you could give the link i download this one and try it directly

I searched a little bit but can t find it for JY 3066 800 x 480

i thank you for the guidance.

Ron
[MTCB Software Development] typos1:
Oh sorry, I dont think there is an RK3066 version, there maybe an old 4.4.4 on the fileserver but it is down at the moment.
[MTCB Software Development] m00n61:
This is not a software issue and will be the same with any ROM.

It could be a power line issue. At startup, variations in power may affect your unit and cause exactly this behaviour. The issue can be solved but with some minimal knowledge of electronics.

You should check 12V filtering capacitors in the unit (could be dried and ineffective).
[MTCB Software Development] Oldpapa49:
Ahh, The famous fish cap smell I remember so well..
[MTCB Software Development] ronny1960:
yes you could be right this mornning everything works, stations al there and later they where gone also with power turn off

i take unit out and open it make pic of board and you tell me wich capacitators to change i have googled motherboard huifei unit and there,s a copper winding close to the powerplug inside and there are 3 or 4 capacitators i think you mean this 3 or 4 and then replace them.

i have this indeed with any rom i used stock from joying a different one from joying and now with the fuse rom

there is a electro shop near my house, so capacitors are not rely a problem solder them out and in alsno big deal.

Thanks for pointing in to the right direction,

Ron
[MTCB Software Development] m00n61:
I suggest you first check the wiring. Do you still have the wiring diagram attached to your unit? It should look like the one in the attached picture.

Make sure the red and yellow wires are correctly attached, most important you should have permanent 12V on the yellow wire - even with no key. The red wire gets 12 V only with the key on "accessories" or "ignition". Also make sure you have a good ground, i.e. the voltage measured between the unit housing and the car frame should be 0.

If all these check then you can go look at the capacitors and see if any one of them smells funny or has bulging tops.

HERE is a great article on filtering capacitors and how to check them.
[MTCB Software Development] ronny1960:
sorry for late reaction

Yes i have the original sticker on the unit but a have also wire diagram.

Saterday i will measure and look at the wires and take unit out open it for look of a bad capacitors.

If i find nothing funny i post pic of board so then you can guide a little witch one but i think it the big one close to copper winding

Ron
[MTCB Software Development] ronny1960:
[MENTION=834020]m00n61[/MENTION] hello i checked wiring like you sayed all oke no volts between the ground and chassis unit yellow wire +12v and red only 12v when ignition key is turned in accessories stand.

Picture of board here http://imgur.com/a/6oXjM

Strange effect now is that waiting for more than 30 seconds unit das not boot again,turning key after 30 sec. unit is directly ready no boot ?.

is this also effect of bad capacitor.

Nothing has a popped cap ore smells funy inside !!

So can you tell me at first sight of pic wich capacitor or should i take it to a shop wich repairs tablets ?

Greatz Ron
[MTCB Software Development] m00n61:
Board looks OK at first sight so yeah, taking it to a repair shop sounds like the best idea.
[MTCB Software Development] ronny1960:
oke i will not mess with it and take it to a shop. when a go somethimes to a phone repair shop and tell that a have a android car radio unit they all look at my of a become from different planet "you have a whot" so here its not embedded to put this unit in your car.

Thanks for your help if a now more from the shop (this is a good one hy repairs android phones and tablets) i will let it you know

[MENTION=834020]m00n61[/MENTION] still searching for my sound problem i think i found solution for fm tuner sound.

i think this is the english version of 4pda

https://w3bsit3-dns.com/forum/index.php?showtopic=695716&st=300

and then scoll to post #311 here is a solution for fm tuner sound on JY board ,but i do not know how to implement this.

in the 3 picture is talk of capacitors and resistors, must i take the old one out and replace them with the parts listed under the 3 pic?

Ron
[MTCB Software Development] m00n61:
Are you familiar with de/soldering SMDs? This kind of hardware mods are not so simple and it is very easy to permanently damage the motherboard.

The post you mention shows several different mods for different types of motherboards, all involving the replacement of several SMDs so, if you have one of the models described in the post and are OK with messing with SMDs then go on.
[MTCB Software Development] ronny1960:
Hello m00n61 i have the JY model mentioned in the post

i will not do it myself reparing smd,s (i will never get that right)

i found after phoning and mailing several shops,one shop that will fix it for me voor 10 euros, but in the post on the site mentioned there is no speak howe much the voltage must by of the smd capacitors (0,1 V or 0,3 V or more)

Do you Know ? how much the minium voltage could be of the capacitors,

i found a datasheet of tda 7706 and thats about 0,1 v (i guess it was a bad ready pdf)

But i thank you for the support on this

[MTCB Software Development] Tumke32:
I noticed something strange. In the past i flashed several roms on my mtcb-mx carstereo. Also dsa 5.1 rom. I few months back i went back to boorendook 4.4 rom. Today i looked in settings and is Saw that my mcu is changed to mtcc-kld2 2.275. i this because dsa rom spoofed the mtcb to mtcc or has It nothing to do with that. If not...it means that its possible to install another mcu type on a Mx carstereo (in this case kld2).
[MTCB Software Development] typos1:
AFAIK know [MENTION=6041319]dsa8310[/MENTION] only spoofs the OS rather than actually change what MCU type is displayed in the about device field. Apart from BN and HA MCUs which are known to be interchangeable I think this is the first time we have someone report a device fully working with a different MCU on it.

[MTCB Software Development] m00n61:
Hi Ron,

Sorry for the late reply, I was traveling and had random access to internet.

Since this is a 12V unit capacitors should be at least 12V(16 or 25 is better). However, this is mainly interesting for large electrolytic or tantalum capacitors, ceramic ones will resist several hundred volts without issues.
[MTCB Software Development] nicolapit:
is there some function or some apk or some hardware modification for increase or decrease screen's contrast and brightness? I don't see well the display with the sunlight, can it be improved?
[MTCB Software Development] m00n61:
short answer: no

These are cheap units using cheap LCD panels. Don't expect AMOLED contrast.
[MTCB Software Development] typos1:
AMOLEDs are known for their lack of brightness compared to normal LCDs, particularly in bright sunlight . . .

Someone on 4pda has added some hardware that allows adjusting the brightness.
[MTCB Software Development] nicolapit:
can you send me the link to the discussion please?
[MTCB Software Development] typos1:
I dont have it I m sorry, your ll have to look on 4pda.ru.
[MTCB Software Development] m00n61:
I don't know where you get your info. That was maybe true 10 years ago :)))

Samsung Galaxy S series rule in term of sunlight legibility and all use AMOLEDs.

Here's a comparative test:

[MTCB Software Development] typos1:
Recently bought a new phone and read lots of reviews of lots of phones and many many times I read how AMOLEDs arent as bright as LCD screens. Also AMOLED screens really oversaturate the colours in my experience. I also bought a 2nd hand S6 Edge and was not impressed, not so much with the brightness (unless I m in bright sunlight I have my screen brightness on almost the lowest setting anyway) but with the colours theyre way too overs atured for me personally.

why 7floor's sound mod doesn't work on the latest booroondook's rom 5.1? I have RK3188 my head unit is rooted, xposed is installed, I only copied libjnidispatch.so to /system/lib and the permissions were already to 644; I have files i2c-0 .. i2c-4 under /dev directory and MTC Sound plugin is enabled in xposed, In the log it says MTC Sound status: mcu, Error setting permissions for i2c devices files, possibly root access.... on malaysk's ROM it works fine without no problem
[MTCB Software Development] typos1:
I get the same error message on [MENTION=6041319]dsa8310[/MENTION]'s latest ROM, but I didnt get it on booroondook's latest, strangely, especially considering that dsa has done 7floor's mod to his unit.
[MTCB Software Development] warata:
Did you check the enable su during boot?

I don't have any problem the booroondooks 5.1.1 with mtc-sound2.0.5 by dsa.

And I don't do "copy libjnidispatch.so to blah blah blah"

Just install mtc-sound and activate it,finish.

[MTCB Software Development] Johny DJ:
If you install twrp recovery you can but I think no one did this... So simply answer is: you can't.

You can do it by 3rd party apps but the problem is you cannot restore...
[MTCB Software Development] oldman_58:
try on-line nandroid backup https://play.google.com/store/apps/details?id=com.h3r3t1c.onnandbup

it works well.
[MTCB Software Development] nicolapit:
I know that app and I saw a video on youtube some year ago https://www.youtube.com/watch?v=HM4mWvgCnpU

but I don't have trust in them because as already told by Johny DJ after you can't restore the backup

as you can see here https://twrp.me/Devices/ on the official website of TWRP there isn't the recovery for our devices but only for phones

maybe the developper of booroondook's rom could tell us how to cook the rom with our favorite apps
[MTCB Software Development] pcmender2005:
There is TWRP image on filesever but think it's for jy unit not sure never tried it. Edit sorry my bad it's KGL.
[MTCB Software Development] typos1:
TWRP is not advisable because you cant flash MCUs and for other reasons that I cant remember (search the original thread if you wanna find out).

Why dont you simply use the app "apkextractor" to back up your apps and re-install them ?
[MTCB Software Development] nicolapit:
yes you can create the backup with online nandroid backup, I have done it on my old Eonon time ago, but if you want restore the backup you must install TWRP recovery on your device and you can't because you need a specific TWRP recovery for your device and the developpers didn't released it, if you try to install it you could brick your head unit
