Please help!

Today I tried to install the firmware v 1.85 from this message.

At first I tried to install it from working mode. But it was not installed and after reboot I see the message about package cheging was failed.

Then I tried to install firmware from recovery mode. But installation was with errors and my device was automatically shutdown.

Now I cannot turn on my device. When I press Power button I only see logo with "Platinum RM" (I suspect that this logo relates to new 1.85 firmware because I never seen this logo).

And now I cannot boot my device to recovery mode (according to instructions in the first message).

And also I cannot boot my device to bootloader mode. I tried this according to the instruction in the first message and also instruction in the Wiki.

My PC doesn't detect the USB connection.

FYI: My Device is 7618 model (Toyota Universal)

I downloaded it from the second link after googling :

www.devfiles.co/download/nzmXh3xF/gapps-jb-20130812-signed.zip

Open the zip and search for the GoogleCalendarSyncAdapter.apk . I didn't install it yet, yesterday I sat in the car head down to install the unit, today my back is sore ... But rear cam is working, GPS is working (TomTom), DVB-T is working, radio is working, Poweramp is working. I have to tweak the mixing of GPS and radio, seems not that simple as I thought. I guess overall settings take place only after a restart of the unit. Searching for a descent active DVB-T antenna now. Anyone some suggestions?

Next on my list is playing with Torque once the BT dongle arrives, and connecting my cellphone
[MTCB Android Head Units Q&A] J0sh_FG:
Why would you even try to put that firmware version in your "KGL" headunit in first place? That's an update for Roadmaster units. They have custom MCU version called "RM1", the same way Klyde radios use a "KLD" type.

The member who posted this update even warned you about that. Just...wait for KGL v1.85 release. Patience is so underrated these days...

I'm really sorry and I hope you can fix your radio somehow.

Cheers

I want to install my old firmware, and I have it. But I cannot turn on bootloader mode. Maybe there is another method?

Hello there,

I proceeded to update my KGAC-7682 device for Mercedes and I confirm that the radio works fine with the file mcu.img taken in MTCB-KGL1.

- MCU version: 1.77

- Android version 4.2.2

- Kernel version: 3.0.36 May 14 03:45:57 PDT 2014

- Build number: rk30sdk-eng4.2.2 20140514.19:44:15

Thank you for the work and information.

I haven't used Titanium backup before, is it possible to do a backup which will restore my screen layouts/background/app settings to the way they were before a firmware update, and still be market linked ?

If so, which option should I choose in Titanium backup - I'd like to try a new firmware, maybe it'll sort out my radio.

(this question specifically relates to changing firmware versions)

Bluetooth Headphones

Has anyone been able to pair Bluetooth Headphones to the HuiFei units, I have the KGL-7302 specifically. I have two different models and can't get either to pair. The HUIFEI can see the headphones but does not add them. I'm wanting it so my son can listen to his videos and I don't have too.

Does somebody here knows if I cann get the Dashboard infos on my Navi?

I am trying days with different apps , like changing Canbus, try to install carinfo app( doesnt open the app), noway...Everything else is working gps,sound, BT, when i put to reverse gear it shows "no signal" ( i dont have cam installed). Behind my HU are Key 2. and AMP not conected only Key 1.

I thought to buy a cam bit i dont know if reverse sensors will work on my navi. Now it shows me only in my small dashboard and this nervs me. SWC volume- + Next and Rew are working but up to the wheel are other 4 buttoms which are without a funktions.

1. cann somehow dashboard infos be placed on HU?

2. if i buy a reverse camera would show my parking sensors on the HU

3. SWC upper buttoms

Thanks to all here...
[MTCB Android Head Units Q&A] elkabong007:
This happens to me when i flashed new firmware, and what really happens is flashing erases the previous factory setting. you must select the correct radio chipset in the factory setting to correct your radio problem.
[MTCB Android Head Units Q&A] kaween:
Indeed. I too would expect somehow the selected FM chip type is wrong although Edit states he's pretty much sure he's running the correct setting for the radio chip.

[MENTION=309187]edit[/MENTION] : did you only update the Android update.img or did you change the mcu too ? Because in all anrdroid unit's I've used and tested so far, the Android part has not that much influence on the Radio chip : the radio apk is "just a graphic interface" that visualises the result of the communication between FM-chip and MCU and it provides a UI for the user to command the radio chip.

If the MCU settings get screwed up somehow (bad mcu, wrong setting) you could get such a "my radio not working anymore" result - basically, it SHOULD react that way if something's wrong with the hardware profile that the mcu is reading-.

But _just_ by updating the android part of the unit ? Should not have any influence as I understand the workings of these android car units in general.

But I remember a remark about resetting the unit completly after flashing an update as the previous setting parameters may be wrong for the new flashed firmware : in such a case, it could be possible that you still "see the correct setting" when looking at the factory settings screen, but the unit is actually running a completly different (and wrong) internal setting. I know this can happen on the AN21-U for example : after a flash, the config menu could show a certain BT-chip version to be active when in fact, it was not resulting in a failure to operate the BT board.

To solve it, you'd have to "select the wrong one, reboot, and select the right one again" to force the unit to re-initialise the correct hardware config file for the mcu although when you inspected the settings screen, everything looked okay.

What happens if you choose "the wrong one" (providing you did make a screenshot or noted down the original settings before starting to experiment ?), apply, reboot, go back to the factory settings, choose the correct one, apply, reboot ?
[MTCB Android Head Units Q&A] Udonitron:
Yeah total brainfart with the rar files, I know better lol.

So essentially I just need to backup, install some recovery software, reboot into recovery and flash the pre-rooted new rom, yeah?

The img is essentially for recovery back to stock firmware then?

The 1st page has info all over the place so it really follow a fluid 123 kind of layout like most rom threads do.

I assume Torque OBDII fine on these roms?

I mainly just need more app space.
[MTCB Android Head Units Q&A] KilrPilr:
Unfortunately Ive tried 5 or 6 different recorder apps and nothing has worked. Ill try some more later. Didnt think about a rca to usb converter. Ill have a look around and see. Thanks for the suggestions :)
[MTCB Android Head Units Q&A] edit:
No, I've updated only the android part. Read about the MCU and I was aware not to. It was odd sudently the radio had very low signal.

After I flashed the KYD firmware it came back to life.

I did not reset to factory because after flashing it wipes everything automatically so I thought that an factory reset was not necesary.

Thank you !

---------- Post added at 12:25 AM ---------- Previous post was at 12:19 AM ----------

I tried that. Entered the menu, changed the default one (that somewhat worked but had very low signal and extremely bad sound quality, like I said the automatic scan could not pic anything but if you go manually you could find some stations) with other 2 models, rebooted each time but each time there was only silence..... no hiss, no noise, no buzz.. it did not worked so i gave up after 2-3 tries and flashed another firmware (like i said, till i found one that worked).

Thank you for the feedback !
[MTCB Android Head Units Q&A] xcuter:
What is the latest MCU for my unit? Don't want dl wrong one.
[MTCB Android Head Units Q&A] edit:
I did not touch the MCU (Haven't seen anything new, in fact i haven't seen any on the file server) I have MTCB-KYD-V2.43

What I have flashed right now is written on the server at 26-Apr-2015 filename "updateKYD1024x600KK4.4.4"

All I needed was a bigger app space and root for Viper4Android.

Do you recommend a different (better) android image?

Thank you!
[MTCB Android Head Units Q&A] kaween:
Good to hear you got it sorted out. May I ask, which unit did you end up with ? The Witson you posted earlier ? Something else ?
[MTCB Android Head Units Q&A] edit:
Yes, the Witson.

P.S. The strange thing is as I am looking at the settings on the working KYD firmware I realize that the Radio chipset model was set corectly on each firmware the TDA7706 but for some reason it did not work the same. Also each time the region was chosen corectly Europe.
[MTCB Android Head Units Q&A] leckig:
I want to supply my Klyde with constant internet, but I am tired of tethering my cellphone.

are there any special requirements that the 3g dongle must meet?

for example, will the Franklin Wireless U770 from FreedomPop work?
[MTCB Android Head Units Q&A] Udonitron:
Trying to root with 2.1.1 so i can backup first but no reboot on my system to do once it is installed so having to use the reset. Updated to the lastest version and it has a language pack for English BTW.

It tells me my phone is too strong and it cannot be rooted. :(
[MTCB Android Head Units Q&A] Brendo:
You need one compatible with android. Search the thread (I posted a link a while back also)

What is 2.1.1?

You have 4.4 already? It cannot be rooted. You need to install prerooted image. Just download a prerooted image, copy the img file to root of sd card, insert in gps (map) slot, android will detect update and ask If you want to install it. This is all in the first post...
[MTCB Android Head Units Q&A] Udonitron:
Yeah doing that now actually :)

Didn't realize the MCU was rooted.

Almost done, cheers
[MTCB Android Head Units Q&A] xcuter:
I tether with my phone too. I use tasker to setup my Hotspot to launch when my phone detects that it connected to my units BT. Work pretty well.
[MTCB Android Head Units Q&A] leckig:
that is a great idea! However, in my unit BT does not connect automatically to my phone. I set the autoconnect switch but in nearly all cases it fails to connect and I have to do it manually.

Additionally, wifi radio in the unit randomly shuts itself off and I have to switch it on manually....
[MTCB Android Head Units Q&A] typos1:
That is strange, though I have heard of it happening occasionally.

Lol, I didnt upload the one you wanted cos I didnt have it, I said I would upload it today but I forgot ! So I guess one of the two I DID upload was what you wanted! ? :)

So, you dont think that they are trying to charge more money because more people want them and you dont think theyre charging more because their stocks are low, so why do you think the price is higher now then ? ! :)

No it does not - the MCU stores its settings to its flash, even when it is updated, the only time it will loose them is if the wrong MCU is flashed.

Yes, youre right, dunno why that happened to Edit.

Agh ! ! I told you before you cant backup without root and you dont need to back up anyway ! ! :)

v2.55. As the first page says and has been mentioned infinite times in the thread, you can use ANY MCU that matches your type !

Theres a couple of MCUs on there and a link to a page with MCUs on. Bearing in mind your radio problem I guess you better stick with that. But usually you can use ANY ROM, I ve tried every type on my Klyde and the radio has been fine with all of them.

Its NOT a Witson, its a KYD !! Witson are just a seller !! :)

Jeez !! I also told you before that you need a pre-rooted image for root - youre trying the 4.2.2 rooting method on 4.4.4 !! (bangs head against wall) :)

The MCU is NOT rooted, whatever gives you that idea ?

Kingoroot, an app used to get root on 4.2.2.
[MTCB Android Head Units Q&A] Udonitron:
Typo there...in the car on the laptop, sorry.

The newest MCU i just updated with, before doing anything, automatically has the app storage at 3GB so I will leave it as is for now.

That was paramount for me.

[MTCB Android Head Units Q&A] dark alex:
Did you Try the App named "Volume control +" and change notification volume with it?
[MTCB Android Head Units Q&A] kaween:
With a larger company, no, and I wouldn't expect this either in this case.

But with resellers : oh yes. I've personally seen replacement boards go from 50USD to "not available" to 150USD within days. I've bought a Bluecore board from a reseller for 15USD, and after a week everyone who tried to get a hold of these at the same reseller either got the "not availabe" answer or a price tag of 65USD.
[MTCB Android Head Units Q&A] typos1:
I m afraid ts already been established that these boards wont fit because the connectors are a different format, plus they are too big.

Klyde say the RK3288 is a long way off, at least the end of the year.

If you do not think they are rising the price to make more money because the SoMs are in demand and you also do not think that they have raised the price because they do no have many left and they want to put people off buying them, then why do you think they have raised the price ? Just to be awkward ? !

Apart from the 3 three reasons I ve listed there are simply no other reasons to raise the price that I can think of.
[MTCB Android Head Units Q&A] dark alex:
Probably just to have a chance to sell full units?

Btw they offered me wholesale prices beginning at 100pcs/Month so i doubt they are on low stock ;)

//Edit:
[MTCB Android Head Units Q&A] typos1:
Ok, but thats the "to put people off buying them" reason :)

Lol, "new tech" , the RK3188 is over 2 years old !! And so is the RK3188/2Gb RAM combo, its been available for ages !!

I asked about the 2 Gb RAM version and they said that their engineer said they couldnt do it cos there was not enough space on the baord for the extra RAM, I had to point out that for 2Gb RAM they would have to use 2x1Gb blocks of RAM , not 4x512Mb !! Then they said maybe at end of the year, or maybe with the RK3288.
[MTCB Android Head Units Q&A] dark alex:
So we're at te point where they seem to tell crap to get us silent?!
[MTCB Android Head Units Q&A] typos1:
No, I just think they dont know too much about the wider market, they only know about the RK3066 and to them the RK3188 is "new". They also obviously did not think about a 2Gb RAM version, I dont think they are lying, just that they do not know too much.

I suspect they maybe do not want to sell too many RK3188 SoMs as they may think it will affect the sales of actual units. Or they simply could have had several big orders in, some people buy orders of 100s of units, so maybe it is true they are running low ? Or maybe they thought $80 odd delivered was just too cheap for a SoM ?
[MTCB Android Head Units Q&A] ErAzOr2k:
Can anyone tell me if delayed shutdown (software based) is also working with KGL MCUs?
[MTCB Android Head Units Q&A] typos1:

The reason I have been using the 2.44 test mcu is everything works well and I have a 2hr sleep/dream mode fixed. The colors in system/element are correct, the audio on for the reverse camera is remembered.

I loose these features with 2.55. Does your script possible fix these? Did you get a select-able sleep/dream to work?

Hopefully what ever is needed or missing to communicate with the mcu will be coming in the next rk3188 firmware release. Hopefully the users with the HD display issues will get a release also.

Another question you may be able to help me with:

I'm still have a occasional animation hang on boot up. Is there a log file I can look at to see what program or process is doing this?

I found current and history of about 15 boot ups in /data/system/dropbox but I am not sure if these are help or pointing to something else.
[MTCB Android Head Units Q&A] typos1:
The first page gives 3 links on how to modify the mic.

I got an email from Klyde saying "the RK3188 1024x600 firmware is still uploading", I ve checked their site and I cant see it.

Although that was pertaining to the 1024x600 issues, not any fix for the shut down delay timer. That may or may not be included in any RK3188/1024x600 update that sorts the display issues.

I also tried a few similar apps, but without success.

In fact, I wonder why is seatbelt reminder and turn signal (too) silent, compared with the rest of notifications (reverse sensor, hand brake, door open...).

With the original HU, they are all at same volume.

I wish I can only make a turn signal louder... that must be defined somewhere, or?

FOBO tire bluetooth TPMS

Hey guys, longtime lurker first post.

I just recently installed my rk3066 running 4.4.4 from autopumpkin (SKU: KD-C0905). So far I love (almost) everything about it. I've been scouring this post to figure out how to root it and all the cool stuff I see you guys messing with.

I found something cool from a company called FOBO this morning. It's a Bluetooth TMPS sensor that has an Android App to monitor tire pressure. They are also about to release another called foboXtra or something that will allow for monitoring more than 4 sensors. So you can monitor a spare tire, or for guys with trucks like me, we can monitor air bag suspension system pressure or even duallys! Just wondering if anyone has any experience with the product. The only issues I can see are because it is Bluetooth, your headunit could only pair either with your phone or the TMPS sensor. Anyway thought I would share my discovery with everyone. Not sure if this it the right place for this post but seemed good as any.
