From where can I found the update to 4.4 ? can you give me the link so I can download that update ?

---------- Post added at 05:30 PM ---------- Previous post was at 05:13 PM ----------

i dont see this version listed KLD V2.20
[MTCB Android Head Units General] m4f1050:
If you dont see it I suggest you dont upgrade to a newer one, in case the newer one does not work on your unit and be stuck with something not working like a knob or button...
[MTCB Android Head Units General] thewesman:
My new GS unit, looks like that means UG Electronics Ltd., has a newer MCU version I don't see listed here.

PF73AA3AR (XTRONS)

SN: 000D18A15208

MCU Version: MTCB-GS-V2.73 ; August 13 2015

Android Version: 4.4.4_26082015

Build Number: rk3188-eng4.4.4 26082015

CPU: ARM Cortex-A9 @ 1.6GHz (x4)

Memory: 1024MB

I have asked XTRONS for the MCU, and the KitKat image that came with the unit... but they are totally playing dumb.
[MTCB Android Head Units General] m4f1050:
I would wait for them, or if youre feeling lucky like I did, just install update.img, no mcu.img
[MTCB Android Head Units General] typos1:
I dont get the UG Electronics bit - what makes you think its them ?

Xtrons are dumb - theyre just resellers.

---------- Post added at 08:58 PM ---------- Previous post was at 08:53 PM ----------

Nothing to do with luck, you can install MCU and update.image separately, always have been able to.
[MTCB Android Head Units General] m4f1050:
You did not understand what I said. I told him to either wait for the stock rom to be available or try his luck and only install update.img
[MTCB Android Head Units General] thewesman:
I read in the Wiki that the 2-letter seems to infer the maker. My actual unit came in a factory fresh box from UG Electronics, with a pretty XTRONS box inside... which leads me to believe UG is the actual manufacturer of these units. Just a hunch really.

---------- Post added at 10:22 PM ---------- Previous post was at 10:16 PM ----------

Thanks dude, I ended up putting the Malaysk ROM on the unit the second day I had it installed. I was just trying to get the MCU image for the community. This system has some interesting features like DIS CanBus display, vehicle emblem load screens, and apparently a better Bluetooth module (my mic and volume sound good).
[MTCB Android Head Units General] typos1:
Ah, I see, interesting, thanks for the info, although I d expect the MCU to be something like "UGE" if they were the manufacturers.

---------- Post added at 09:29 PM ---------- Previous post was at 09:22 PM ----------

I understood you perfectly and like I said, there is no "luck" involved - you do not have to install the MCU and update.image together. :)

---------- Post added at 09:32 PM ---------- Previous post was at 09:29 PM ----------

Can you post pics ? - all units have had vehicle emblem load screens and some form of CAN Bus display since they came out - I m interested to see if theyve been updated.
[MTCB Android Head Units General] m4f1050:
Jesus Christ, when did I say he HAD to install both? You know what, forget what I wrote, he understood me.
[MTCB Android Head Units General] typos1:
Calm down dear :) - using the word "luck" suggested it may not work.
[MTCB Android Head Units General] m4f1050:
He mentioned it was a unit that the mcu thread had no mcu.img, so I would call it lucky if it works... like everything here, its use at your own risk. :)
[MTCB Android Head Units General] NemeGuero:
Hi

does anyone know what the difference from JY v2.68 and v2.73 is?

the version on my unit is currently v2.68

Does the 2.73 have the modified(upgraded) sound processor?

THanks!
[MTCB Android Head Units General] raggatwins:
hi m8ty

just been sent the image for xtrons ta696A if thats any good kitkat 4.4.4 :)

cant link yet as not got 10 post's to my name :( have to go on a troll to knock up the numbers ...
[MTCB Android Head Units General] typos1:
Theres no changelog for MCUs I m afraid.

Only MCUs modified by Dark Alex have the sound mod and your ll have to look in the list at the beginning of the thread to see if hes done it to the one you want.

Thanks, but theres no such thing as an "Xtrons ta696A" - Xtrons are sellers only, they just re-badge units made by the manufacturers, look in settings/about for what machine you have so we know what version the update is for, unless you mean you have a GS version like in the post you quoted, in which case we need to know what screen res its for.

If you pm me with the link I can upload it for you.

Also, this thread is for MCUs, when you say "image" do you mean an update image for Android or an MCU ?
[MTCB Android Head Units General] raggatwins:
Any joy in finding mcu for the td696a as in real need for it right now :( allready have the factory firmware for it .
[MTCB Android Head Units General] typos1:
As I just said, theres no such thing as "td696a", look in your settings/about screen to find out what unit you have and what MCU type you have and therefore which type you need to update it.

Also you DO NOT need the MCU to update the Android firmware, they can be done separately.

If you DID mean you have the same unit as [MENTION=7297653]thewesman[/MENTION], then you have a "GS" unit and you need a GS MCU, AFAIK 2.73 is the latest GS MCU anyway.

Kld 6 2.81

Hi

Could anyone point me in the right direction. Looking for MTCB KLD 6 2.81 for my Pumpkin RQ0364E , updated to v 2.83 & now my on/off, home, Nav & volume touch buttons don't work.

Any help very much appreciated :good:
[MTCB Android Head Units General] typos1:
See if anyones poste in this thread and check out the links to the Mega site where theyre uploaded.
[MTCB Android Head Units General] gk66:
I currently run KGL MCU 2.55 I've no problems with it and do not intend updating unless the benefits outweigh the risks. I see the same version available with redesigned sleep and audio handing by darkleo but can't find any info on what if any improvements this would bring.

Does anyone know the specific enhancements that would allow me to decide whether to risk it.

Thanks

gk
[MTCB Android Head Units General] typos1:
Dont worry theres no "risk" involved in changing your MCU, if something doesnt work you can just change back, in the 2 and a half years I ve been on here theres been very few problems with people on here updating their MCUs and when there are thy just go back to a version that worked best for them.
[MTCB Android Head Units General] m4f1050:
What if the original is not available for dowoad, how exactly would you change back to it? :)
[MTCB Android Head Units General] gk66:
Thanks for that. A few folk have basically been saying if it's not broke don't fix it. It's not broke but I'm curious about the work of darkleo and whether I'll see any benefits using a modified MCU. Improved audio controllability would be a reason to upgrade if that's what the redesigned sound processor does.
[MTCB Android Head Units General] typos1:
Soz, forgot to say about Dark Leo's mod - I think it sounds better (I ve been using his version for the last year), so do lots of others, best thing is to give it a go and see what you think.

Of course theres always the other mod that gives Android full control of the audio chip which apparently gives a massive improvement in sound quality, its in the hardware section and it involves some soldering though, I ll be doing it at some point in the future.
[MTCB Android Head Units General] gk66:
Thanks mate. I think I'll try the modded MCU first. Will leave soldering for another day!
[MTCB Android Head Units General] balders01:
I now have the v2.81 from autopumpkin. Flashed it last night' touch buttons are still not responsive. It seems to have lost its config keys ? I do have the steering wheel controls to fall back as they are fine, is there anything else I could try ?
[MTCB Android Head Units General] typos1:
Try the previous MCU and see if that one works.
[MTCB Android Head Units General] :
None of the mcus are solving the problems

[MTCB Android Head Units General] themissionimpossible:
IMHO there must be some settings that are model-specific and not included in a generic MCU file because this file must be suitable for more HU models assembled by the same manufacturer (KLD, KGL, etc.)

These settings are initially configured at factory and definitively wiped away by flashing a new MCU... unfortunately the user has no way to access and reset all the original values through the factory settings menu, and neither reinstalling the original MCU (generic) version can recreate the correct model-specific configuration.
[MTCB Android Head Units General] balders01:
Thanks..... the mission. Have emailed Autopumpkin, not expecting much help as I flashed the MCU but you never know !! They seem very helpful.
[MTCB Android Head Units General] m4f1050:
Thats why I say DO NOT update MCU unless you can get the stock MCU it came with.

---------- Post added at 10:20 AM ---------- Previous post was at 10:06 AM ----------

Not the ones for DL, but the stock one that came with your MCU.
[MTCB Android Head Units General] themissionimpossible:
The problem is just where to get it, maybe directly from the manufacturer if willing to help...

However I suspect that at factory the manufacturer uses some special tool/utility to setup some hidden configurations like:

buttons (physical or touch) enabling and mappings

radio tuner module setup

the 2 most common malfunctions occurring after MCU flashing and very often not recoverable.

In this case, also getting the original factory MCU couldn't succeed to completely restore a full HU functionality.
[MTCB Android Head Units General] m4f1050:
I get mine from Autotop (seller of YINUO MCU's and I am sure they get them from the manufacturer?)

The one I posted in this thread is a stock one, not modified with sound but hey, I thought it would be a good idea to share it, Autotop got it for me since I downgraded to v2.80 and all hell broke lose on my unit. I had to install the v2.83 I got from them...

I see what you mean though, they have some settings that are not accessible very easily or maybe not accessible at all? Interesting, maybe that explains why my buttons stopped working on my F150 radio, but they are hidden so I never cared to find out why or how to fix it. That would be something to really look into, maybe that's how all these MCU flashing mistakes can be resolved..?
[MTCB Android Head Units General] typos1:
Sorry, but this IS NOT the case.

Why are you bothering with pumpkin ? They are just sellers, get the MCU from the manufacturer or this thread. Shenzhen Klyde make your unit, find them on Alibaba and email them.
[MTCB Android Head Units General] balders01:
Great minds think alike Typos1 .... emailed Klyde last night, had no response as of yet. Had another reply fro Autopumpkin with another firmware, so will see what that does !!

Thanks for the advice
[MTCB Android Head Units General] typos1:
By "firmware" do you mean the Android side of things or the MCU and Android ? If they are different from anything thats been uploaded before can you provide me with a link so I can upload them ? (If you dont know already, you can flash the MCU and Android side of things separately, you dont have to do them together)
[MTCB Android Head Units General] balders01:
Yes Android side its a little larger, not by much. 1st one they sent was 684.5MB this one is 688.7MB.

Yep can upload not a problem, not sure how to do that mind & am at work so wont be able to do anything until later today. I also have the V2.81 MCU
[MTCB Android Head Units General] typos1:
Sounds like its a different Android version, has it got a date on it ? No rush if youre at work, pm me the download link if its easier, so the MCU is the same as the one youve got already that doesnt work properly ?
[MTCB Android Head Units General] balders01:
No date on the Android firmware, the MCU is V2.81 which is the one the unit came with. I will PM you the link from my gmail for both if you like.

Paul
[MTCB Android Head Units General] typos1:
Oops, soz, its was 2.83 that didnt work, have you got your button controls back ?
[MTCB Android Head Units General] balders01:
Nope still not working, hoping that that new firmware will sort it !!!

PM'd you have you received it
[MTCB Android Head Units General] typos1:
Yes, thanks, just eaving for work now so I ll upload it later, be useful if you can tell me the date and version from the about screen when youve flashed it, but I really dont think it ll help the button issue though as thats controlled by the MCU not the Android side of things.

I ve read about this occasionally over the last 2 and a half years, but I cant remember how it was sorted I m afraid, all I can say is search the original thread to see if you can find a solution.
[MTCB Android Head Units General] balders01:
Yep will do, hopefully flash it tonight if it stops bloody snowing .... Lol
[MTCB Android Head Units General] balders01:
Update... Update new firmware installed & guess what all buttons now as they should be , Thank God

What exactly does the darkleo mod do? Trying to decide if it's worth downgrading to the older mcu (joying unit)
[MTCB Android Head Units General] Mr Bigglesworth:
Hello,

Could some one please help me with knowing how to backup my existing MCU (I have MX2.72 which isn't listed here).

Also does updating the MCU reset your device?
[MTCB Android Head Units General] typos1:
Great, glad its sorted!

Improvements to sound quality, try it and see what you think.

You cant back up MCUs, updating it does not reset your device.
[MTCB Android Head Units General] Mr Bigglesworth:
Thanks.

So is there a way to extract my current MCU firmware. Just wondering because if I update with the latest MX version, and then want to roll back because there is some kind of issue, I assume I need to have it saved somewhere?
[MTCB Android Head Units General] typos1:
No, theres no way to back up or extract MCUs, but there are 3 MX MCUs at the begining of this thread.
[MTCB Android Head Units General] Mr Bigglesworth:
Thanks typos1 - appreciate the info.

Next possibly silly question but how are people getting these MCUs if you can't extract them from the HU?

(I'm also currently on MX2.72 which isn't one of those listed on the front page)
[MTCB Android Head Units General] m4f1050:
That is correct. Do not update MCU unless you have the stock one handy.

---------- Post added at 11:45 AM ---------- Previous post was at 11:44 AM ----------

From the manufacturers. I got my stock one from my reseller but they have a good relationship with manufacturer...try both.
[MTCB Android Head Units General] typos1:
This is NOT necessary - he can use one of the THREE MX MCUs in this thread.
[MTCB Android Head Units General] m4f1050:
Ok, if he runs into problems do you want to be the one who told him "go ahead, everything will be alright" and then "BOOM, no buttons?" I sure wouldn't.... At least from other posts that's what's going on with some of the users here.. FWIW testing "better" sound is not worth messing up buttons unless you have no knobs/buttons that you can't replace with steering wheel control, my $0.02
[MTCB Android Head Units General] typos1:
Thanks, but as I said, there are THREE MX MCUs posted in this thread so if he runs into problems he can go back to one of them.

Is it possible to repair KYD MCU 2.55 with Darkleo modification, or create new one? Because 2.55 is not working with steering wheel control buttons and it is not just my case. I was waiting for a half a year and nothing happened and I dont wanna push it but it would help me with music quality a lot.

Thank you

[ONE General] evronetwork:
Hi there guys,

Although active in the rom part of the 1+1 forum, I rarely spend any time in the general section and I thought why not post something? so a little backstory on the cable.

I want the fastest way to charge my phone and what can I do to improve that?

- Get a better charger

- Get a better MicroUSB cable

Our stock charger is capable of 5v 2.1A well the actual amperage it can give is less than 2A, I can't draw more than 1.8-1.9A on my phone even with my custom cable

So I got a quickcharge 2.0 charger just to try it and have a spare one, finally it became my main charger as it's rated at 5v 2A but actually can output 2.1A!!! phone is drawing that much, ranging from 2 to 2.1A - with stock cable it's a bit less than 2A but pretty close(around 1.97A to be precise)

So how's this custom cable I've build? it's like this:

[IMG="Custom MicroUSB cable"]http://oi63.tinypic.com/2zfqut1.jpg[/IMG]

So it's a 18AWG and it's rated for "Maximum amps for chassis wiring: 16A" and "Maximum amps for power transmission: 2.3A" ..so it's capable of sustaining 2.3A without any problem(heat or power loss), if you use a very cheap microusb cable it can take up to 6 hours to charge your phone(as you can imagine the cable can play significant part) - Cable wire is of course copper so you know
[ONE General] naeem76:
Nice work, I've also noticed I get 1.6 to 1.8 amps on stock cable and charget
[ONE General] pbergonzi:
Very nice. Maybe a photo tutorial or youtube vid on construction?
[ONE General] evronetwork:
I'm close on stock(cable+charger) :p

I'm too lazy to do that hhahaa(as a computer tech guy I do many stuff and I have record many of my actions but I'm too lazy to edit my videos and post them online), but honestly trying to fit an 18AWG cable in a usb and microusb jack is pain in the a** because the wire is quite thick :p but it's an one time hassle, I permanently fix the wire(can't be removed even if I wanted to, the only way to fit new microusb and usb jacks is to cut the wire) - Trimming plastic inside the jacks without doing any damage just to fit the cable can be time consuming :crying:

Something that I didn't mention is the size of the cable, its the same size as stock :D

P.S. At best you'll find 20AWG cables in the market and some cost quite much
[ONE General] pbergonzi:
Thanks. Really I was simply wondering to which contacts the wires went, but I'm sure the layout is on the web, and I'm probably not gonna do it anyway.
[ONE General] evronetwork:
If you were close to me(same town or next one) I could do it for you for a small fee :p but don't do it if you're not very capable with ur hands and soldering iron

P.S. soldering them wrong can actually damage the phone permanently or even make the batter explode and/or charger(it's basically a short circuit) - you've been warned :D

My jacks are filled so after I solder the connections they can't be removed ..there are airtight :D also this cable is suitable if you use public chargers as no data would be "stolen" if one of the public chargers is modified - this uses only two wires and it's for charging
[ONE General] pbergonzi:
Nice work. Thank you. The data security is a nice feature.
[ONE General] evronetwork:
On the bad side, if you need to transfer data you can't with this cable ..but I rarely use cable for data(I mostly use wifi connections to transfer data, or bluetooth) - Why? unessesary small-chargings will harm your battery, so if you connect the phone to your computer to transfer data better let it charge up rather than do your job and remove it, less than 1% charge frequent uses it will shorten ur battery life significantly

Even if I wanted to make it a full fledge cable with 18 AWG wire this is impossible, also it will become heavy for a usb cable. I barely fit 18 AWG cable(but it's capable of up to 2.3A(constant use)!! our phones can't draw 2.3A(no phone can ..at least not one I know) so it's great)

I wanted a wire with 2.1A constant use so it would have nearly no power loss(or voltage drop), putting a thicker wire won't make any different but 18AWG compared to stock, there's different. Especially if you compare a cheap 1 euro Chinese microusb cable with this one

--------

Although I'm really happy with my cable and it's my first pick when in hurry and need the faster charge available, two days ago the Chinese were celebrating something so I've bought cheaply(compared to original price) a Wsken magnetic micro usb cable(original), if you don't know whats that it's a microusb cable with magnetic tip. How does it work? check the picture:

I'll measure charging rates when received but I don't expect to be as good as my cable ..but in the night when in the dark a magnetic connection seems wonderful(also great if someones trip in the cable ..it won't make ur phone fall, it will be disconnected). If you put it backwards, it still works(but only for charging) so you can safely use it on public, just connect the cable in reverse. What's bad about this? well this comes with 2 microusb adaptors and one cable, you need that specific cable so if you have lots of devices you need to carry a cable with you(and it's not cheap) - Hope it has similar thickness as our stock cable so charging won't take long, can't wait 5 hours charging(as with some very cheap microusb Chinese cables)
[ONE General] pbergonzi:
Very good, thank you.

I'm a big numb-nut in terms of electrics, but when you're pushing the capabilities for charging, is there also an increased risk of damage?
[ONE General] BarnOwl:
experience?

Did you recieve this cable? I'd like to know your experiences. I know for a fact that the Znap cables are experiencing a lot of delay but there are a lot of Ebay clones on the market now.

Was going to buy this one but I have no clue if it works though.........
[ONE General] gyanbhartip:
How do you measure the current drawn by the phone while charging?
[ONE General] evronetwork:
Yes I receive the cable(if ur talking about the magnetic one) and charges up to 2.1A ..max amps for our phone

Too many apps in the internet but I prefer the "Charger Timer", measures from 20% until 80% ..where the phone gets the "fastest" charging because when battery is low or way to high it draws less power(so battery will last longer)
[ONE General] gyanbhartip:
Thank you. I will give it a try for sure.
