From what I've learned so far, the Roms are edited versions of the original firmware. So, KLD(whatever number you have) will work with KLD(whatever revision you want to reflash). The kind "KLD" and the screen resolution are necessary details.
[MTCB Software Development] typos1:
Cool. :)

I assume youre referring to [MENTION=6041319]dsa8310[/MENTION]'s modified MTCC ROMs ? If so then if you have to flash one of his previous MTCB ROMs first if you have a KLD MCU that doesnt work with an MTCC MCU or any toher MTCB unit and use an app to change the "C" at the end of the MCU to a "B".

If youre not talking about his ROMs, then for ALL MTCB ROMs it does NOT MATTER what version you have (KGL, KLD, JY, GS, HA etc) you can flash ANY MTCB ROM on your unit you like as long as it matches your screen res and processor type.

[MENTION=882008]dvpmike[/MENTION] was referring to the fact that has a KLD MCU and the previous advice that if you have a numbered MCU (eg KLD2) then you should not use an MCU with a number after the manufacturer code, this is now wrong and sometimes you CAN use a numbered MCU on a unit that came with a non numbered MCU (as long it is the same letters in the manufacturer code).
[MTCB Software Development] AlfredKinsey:
I guess the question that stands now (after that elaborate explanation, thank you) is... What's the most preferred (commonly used/liked) rom for the KLD 1024x600 head units?

Can you guys all recommend your preferences here, then us noobs can get an idea of what to try first?
[MTCB Software Development] AlfredKinsey:
I've flashed a version of Malay's modded rom that I'm liking, except for 2 very irritating issues:

1) The GPS is not adjusting to my actual timezome, it's adding 7 hours that I can't seem to fix. (I.e. It's saying 9:18pm at 2:18pm) This is an issue because it's seemingly causing my screen briteness to automatically go to 0%. There's a "crescent moon" icon at the top left side of my screen, I assume this has something to do with it. It's driving me crazy.

I finally got an OBD2 connector to connect to the unit, but torque won't see it. I got some others on Amazon to try a few out, but my head unit will not un-pair from the first one it paired with, won't forget the device, won't re-connect to it now that I've tried others. It will find and connect to my phone, but refuses to pair to a new obd2 Bluetooth device and forget the old one. Is there a way to compelletely recent the Bluetooth device, so that it forgets everything, so that I can start over?

Any help I am very grateful for, thanks everyone.
[MTCB Software Development] War-Rasta:
I have the same issue, but it's an easy fix for me. I just disable automatic timezone in the Date/Time Settings and manually set the timezone to the correct one. As long as you don't move between timezones (I don't even know who's CONSTANTLY driving that much in the first place) this won't be an issue.
[MTCB Software Development] AlfredKinsey:
Nah... I tried all of that, on or off, automatic or not, no matter what I try, it dims itself no matter what.
[MTCB Software Development] War-Rasta:
Is the clock ok after you manually set the correct time zone? 'cause if it is, then the problem with the dimming is something else. I would still set the timezone manually while you keep troubleshooting, just in case.
[MTCB Software Development] AlfredKinsey:
Yes, I have turned off manual dimming, changed the time to the correct one, shut off GPS location and it still does it.

---------- Post added at 06:09 PM ---------- Previous post was at 06:07 PM ----------

I mean, I turned off auto-dimming
[MTCB Software Development] kruuth:
Hi everyone. I managed to get the radio going again. While I was back there I found out why the USB want working now I've fixed that as well. However I can't get mirroring going. I use easy connected by it tells me to connect my mob and then nothing happens. I have an HTC One m9. When I plug in I get options like mirroring, fine transfer, etc. I select mirroring but no luck. I got it working once but no idea how. Usb debugging is on. I've I got a warning that said "no access to the serial number of service hardware". Can someone help?
[MTCB Software Development] AlfredKinsey:
Pulling my hair out

I have tried everything, I've cleared the cache, re-flashed, flashed a new rom, cleared all the data, went into the factory settings and turned the Bluetooth off. THE HEAD UNTIL WILL NOT UNPAIR WITH THE OBD2 DEVICE AND ITS NOT EVEN PLUGGED IN. No matter what I try it's still there, somehow there's some portion of the device memory that won't forget it's there. HOW DO I REMOVE THE DEVICE, SO THAT I CAN REPLACE IT WITH ONE THAT IS ACRUALLY THERE?

Please don't say go to Bluetooth and press "unpair device", I've already tried all common sense options.
[MTCB Software Development] Brendo:
Through both android settings and Bluetooth mcu app?

Have you tried removing power to see if it resets it's memory?

Not ideal, but can you try flashing your mcu?

For someone who has never done this sort of thing before (flashing, etc), you've jumped in the deep end with this device
[MTCB Software Development] AlfredKinsey:
I have ref lashed the device with 3 different Roms, I've turned Google data save off, if used different sd cards, I've gone into system settings and disabled all Bluetooth features, cleared all caches, rebooted and deleted all saved data... THE DEVICE WONT GO AWAY! It says is a paired, but it's not even plugged in. The device doesn't exist to be paired, there's no way it paired, it has no power going to it and no batteries in it. This is just insane... There has to be a way to get the system to forget the Bluetooth device.

---------- Post added at 12:29 AM ---------- Previous post was at 12:27 AM ----------

Are you using the easy connect app that comes on the head unit?
[MTCB Software Development] Brendo:
Not the system setting; the settings in Bluetooth app (the one that allows you to make phone calls/play music)

The Bluetooth on this device is separate to android. the mcu interfaces between the hardware and android itself. It's not like a phone
[MTCB Software Development] AlfredKinsey:
I don't really consider flashing a rom to the device and pairing a Bluetooth device to be jumping into any deep ends... I'm not doing brain surgery here. There's obviously something in the device that is hold on to memory of the paired obd2 device. If there can be something that has potential to remember a device that can or cannot be connected, then logically there's a way to remove the memory of said device. Someone on here knows a way I can clear all saved Bluetooth memory, or memory of any paired devices. There is always a logical answer to all things, wether I know the answer now or later, I will have to learn it somehow.

---------- Post added at 12:37 AM ---------- Previous post was at 12:35 AM ----------

I have tried to remove the device in both the system settings and the "Bluetooth" app... Yes, that is a very simple and logical premise. I am way past simple and logical... I am at the, how do we go into the system and remove this device manually phase.
[MTCB Software Development] Tisho85:
By cut the power off he mean to completely disconnect HU from all cables or easier way is to remove the wires of your car battery. Usually that resets MCU memory.
[MTCB Software Development] Ojeda87:

First time user... Which file is update.img?

Howdy,

I'm running the 800x480 version of the rk3066 with 4.4.4.

The instructions for first time users (that's me) say to not use the fuse but only use the update.Img file.

All the files I see have both image and fuse in their names. Thus I'm confused.

Will someone please tell me where to find the file "update.img" like the instructions say or provide a link to the correct file.

Also is there any special meaning to what Malaysk calls a "Fuse" file? I understood fuse files were temporary files that are supposed to go away with their associated app.

Hope I'm not being to cautious.

Thanks much for any pointers and links.

He's just trying to help you. Clearly you don't understand that these head units function differently from other Android devices. This is due to the fact that part of the hardware is separate from the system, hence the mentioning of the separate chip inside called the MCU (micro controller unit). This is it's own thing and controls the radio functions as well as... Wait for it... The Bluetooth functions!!!

Even those who are experienced within the XDA community would acknowledge that these devices can be tricky as there are so many different variations in hardware and such differences can lead to confusion. I myself even bricked the first one I got before I totally understood what I was doing with these head units, so I feel I am able to explain to you in this way.

Go and read a lot more about these devices and how they function before you go tinkering with yours incorrectly and possibly end up breaking it.
[MTCB Software Development] AlfredKinsey:
Okay, so... I've removed the wiring harness (no power to unit for 5 min and I even pressed the reset button while the power was unplugged). Obd2 device was still paired and connected, even though it is still not plugged into the obd port.

Next I flashed the MCU, turned device on, checked and it was finally gone... Restart the car AND THE DAMN THING IS BACK!!! I FLASHED THE MCU, DELETED ALL BACKUP ETC... It was gone, then this thing that said Bluetooth #2 connected or something like that pops up and there it is.

[MENTION=3590033]Malaysk[/MENTION], you must have some idea what's going on... I've done everything that anyone has suggested, this is insane!
[MTCB Software Development] AlfredKinsey:
I at no point said that he wasn't trying to help me, I also sent a PM thanking for the help... Why you are assuming I don't understand that is beyond me. I took all of his advice, I tried all of his advice, I posted after I tried to let him know that it didn't work. I am not blaming him, I'm merely asking if anyone has a new idea. Please don't assume I am ungrateful, I've made no attempt to attack/blame anyone nor have I been crass.

[MTCB Software Development] hans109h:
A couple of questions and a couple of suggestions.

Q: are you able to pair your HU with other Bluetooth devices than the one you are trying to delete?

Q: did the BT device ever work with Torque?

Q: what's the MAC address of the BT device?

S: Reconnect the BT device and attempt to connect to it.

S: Try all of the other Bluetooth protocols in the factory settings.

S: install torque lite from the play store and see if you can communicate with the device.
[MTCB Software Development] AlfredKinsey:
I can pair it with my phone, but not the other obd2 Bluetooth device I have and not with the one it says it's connected to.

The device never connected in torque, just in the head unit Bluetooth.

The unit has parrot Bluetooth, is it still okay to switch to the others?
[MTCB Software Development] typos1:
I ve never understood the point of a BT OBD device - Bluetooth is designed to link 2 devices together wirelessly so you can move around freely - seeing as the head unit is fixed in the dash. I cant see any benefits at all to having BT OBD, only downsides - its slower than USB OBD, its less secure (can be hacked, especially with "0000" as the PIN !).

To me its as pointless as having a remote control for your smartphone.

Reading all the problems, youre having, [MENTION=7692928]AlfredKinsey[/MENTION] only reinforces my views. Have you considered just getting a proper, fast, secure USB OBD connector ?
[MTCB Software Development] AlfredKinsey:
I have considered it, I was mainly after the convenience factor of being able to leave it plugged in. I also have a wifi obd2 device. Unfortunately I cannot use my hotspot and connect to a wifi device at the same time. Thus making the head unit either torque or music but not both.
[MTCB Software Development] hans109h:
Are you saying the existing factory bluetooth setting is Parrot? If so, yes you can change the setting, BT probably won't work with most of them, but you can always set it back to Parrot, as you know that works with your phone. We're just troubleshooting here.

Depending on the BT OBD device you have there are settings in Torque that control the connection headers and ECU communication speed...you may need to change some of these settings to get your device to communicate with your car.
[MTCB Software Development] typos1:
I leave my USB OBD plugged in, how does BT help with leaving it plugged in ??

Doesnt sound like a good idea, but I cant see it doing any harm. I ve heard of the Parrot BT modules available on MTCB/MTCC units, but youre the first person I ve read about on here with one. It could be the answer to your problems - are you following the normal procedure for BT OBD on these head units ? If so, the procedure is designed for the BT hardware that most MTCB/MTCC units have, not the Parrot module.

Does anything about the BT screen look any different to units without Parrot ? Whats the BT sound quality like ?
[MTCB Software Development] hans109h:
Warning! "Proper" police! USB is a bit more straight forward to connect to, I have both. Yes, it took me a while to get BT to work, but it sure beat tearing apart the dash again to hide the USB cable. Besides that, it sure is convenient when I'm working in the engine compartment and can switch the connection over to my phone and view all my gauges, can't do that with a USB cable behind the dash.
[MTCB Software Development] typos1:
Ok, cant argue with that !! First valid reason for BT OBD I ve heard !
[MTCB Software Development] AlfredKinsey:
No, the factory settings is the only thing that offers a parrot specific setting, it's just a drop down list to select your internal Bluetooth adapter. The only difference between parrot bt and any other is quality of signal. Parrot bt is just more stable hardware, but functions identically otherwise.

My obd2 bt module has a sleep mode that activates after 10 min of inactivity and is secure. Obdlink is the company that makes them, they are hack roof for the most part.

When I connected to it initially, yea I was following the regular procedure to connect, how the unit got stuck thining it is paired to the device is beyond me.

The sound quality of parrot Bluetooth is better, that is the only reason to worry about parrot or not parrot... Parrot has made its name for that very reason. I read a bunch before purchasing the unit, the standard bt models had many many complaints about call quality and a low grade "hiss" when volumes were low. I do not experience any of those issues with my head unit. Unfortunately, I cannot connect any obd2 bt adapters now, because I cannot disconnect from the original unit.

It has to be a memory that is updated after the software is booted up... As I said earlier, I got it to go away when I flashed the MCU, it was definitely off the list. Then somehow it came back, listing as connected, in green letters. After removing the power for 5 min, flashing the MCU, flashing the rom to a completely different rom... I was sure to clear all and erase all backups, it was a fresh boot. The cause has to be winding down to something that is obvious to someone who makes works with these head units. It's in some internal memory device, that isn't erased by flashing the MCU or the Rom, that must be reset in a way other than simply disconnecting the power source and draining the capacitors. There must be a kernel packet, or very simple basic based memory of the device somehow.
[MTCB Software Development] hans109h:
In recovery did you do a full wipe? Prior to installing the ROM? That would be a way to be certain that everything was cleared.
[MTCB Software Development] AlfredKinsey:
With the sd card in gps slot, I choose update and clear all, or whatever the third option is. Then when it gets to boot screen, I shut down wait 30 seconds for full shutdown, reboot in recovery, then choose second to last option to clear all the saved stuff.
[MTCB Software Development] hans109h:
There is a complete wipe option that you could do a couple times prior to installing the rom, I don't know if you did that, but it's worth a try. Two complete wipes and then install the rom.
[MTCB Software Development] pcmender2005:
No problem Dr Dan we are here to help each other we was all newbies once.

Lol They are my grandkids but thanks I will pass on your comment to the parents.
[MTCB Software Development] typos1:
Yes, I ve seen the it in factory settings as well.

It can still be hacked USB is much faster and it CAN be left plugged in.

I know about Parrot and their BT units, so I was expecting a positive answer about BT quality, although I guess you must have had a unit with the standard BT units as well if youre saying its "better" ?

Anyway, youve TOTALLY ignored the one thing in my post that could potentially answer your problems, I shall repeat myself :

"I ve heard of the Parrot BT modules available on MTCB/MTCC units, but youre the first person I ve read about on here with one. It could be the answer to your problems - are you following the normal procedure for BT OBD on these head units ? If so, the procedure is designed for the BT hardware that most MTCB/MTCC units have, not the Parrot module."

Or, to put it another way - AFAIK no one on these forums with these head untis has reported ANYTHING at all about the Parrot BT module and it sounds like it works differently - how did you set it up, did you follow the normal procedure for BT OBD with these head units ??
[MTCB Software Development] AlfredKinsey:
What do you mean...? I answered that question. If you're asking me if I went to the Bluetooth list, pressed search for devices, waited for it to show up, pressed on it when it did, paired with it, then yes... That's he normal procedure for all Bluetooth devices since the birth of Bluetooth connectivity. I had previously said I connected through the normal procedure.

Parrot Bluetooth is not any different than any other Bluetooth, in connective theory... It is purely made from higher quality components, but all functionality is identical.

You're asking me a question that is not clear enough to be answered, if you still feel I have failed to answer it.

Please refrain from being insulting... It isn't my fault you didn't read what I wrote in reply.

---------- Post added at 07:23 PM ---------- Previous post was at 07:14 PM ----------

I'd also like to add, that "Parrot" is a subsidiary of Android, or the other way around as of the past three years or so... So, I'm not sure if you know, but AFAIK, there shouldn't be anything close to functionality problems between android and parrot.

It seems like you are working more towards selling me on your ideals than delving into what the cause is. Perhaps you can just leave my post for someone who understands the functionality of the software, as you obviously don't know any more about the issue than I do.
[MTCB Software Development] AlfredKinsey:
Anyone who can help, please read before replying...

I successfully paired an obd2 Bluetooth device with my head unit.

The device has since been removed from my obd port.

I have made multiple attempts in both the setting Bluetooth section and the "Bluetooth" app on the home screen, to disconnect the device.

The unit refuses to disconnect from the device, no matter that it's not even plugged in or even near the car.

I have flashed the MCU (When I did this, it was gone from the list at first, but the then magically came back somehow).

I have flashed the ROM

I have taken the head unit out and removed its power source for 5 minutes.

I have gone into factory settings and attempted to turn the Bluetooth off and restart the head unit, turned Bluetooth back on, and it still thinks it's connected to the device.

I plugged the device back in and tried to search, found it, it won't actually re connect to it, but still says it's connected to it from the initial connection two days ago.

I'm not trying to be rude, but I have been over this 1000 times, if you don't actually know, please don't reply, I'm waiting for someone who understands these units thoroughly to reply.

It is obviously left now to some internal memory of the device, but because all backups are deleted when the flash (MCU or ROM) I couldn't possibly guess where the memory is stored or how to remove memory of the adapted from it.

[MENTION=3590033]Malaysk[/MENTION] please help of you have an idea.

[MTCB Software Development] RWerksman:
If a reflash didn't work, and you followed the formating instructions that come along with the rom, it's not going to be rom related. You should probably contact the vendor. If you cant, you're most likely out of luck.

FWIW, I'd suggest starting a thread for this issue as opposed to continually posting in this one and engaging with a troll. Neither of you are really contributing anything here with the back and forth BS.
