[LG V20 Questions & Answers] rasveee:
Ok I was getting ghosting which has been getting worse and wore the past month but in the past 2 weeks its been getting really bad on both displays, ontop of that my phone was dying in 20-25% range and going up to 100% charge just to drop like 10 minutes later to like 50% probably just the battery idk

I sent my phone in and here is what they marked on the warranty page

Symptom: Software failure

Repair: Download new software

I honestly hope they don't think its because I wasn't on the latest version of android because I kept putting it off or i'm gonna be pissed, especially since my warranty ends 3/18/2018 and these 2 issues have slowly been getting worse.

Hi!

Here is a working fix if your device is rooted.

[LG V20 Questions & Answers] Jaws4God:
so is this an LG LCD specific issue ? I am just curious when I switch phones should I consider AMOLED / OLED or stick with LCD but maybe a different vendor ?
[LG V20 Questions & Answers] dark_prince:
The culprit behind this is low contrast with high blue-output or cooler color temperature. If you are rooted, you can easily tone down the blue channel by a count of 20 (out of 256) and all is good. Also you don't have to use the phone as maximum brightness all the time, the screen itself is way too bright even for the least level.

2ndly, this ghosting is temporary and develops over time of use. It goes away for LCD.

OLED screens suffer from the permanent ghosting aka burn-in, though its coming over time is delayed by quality and improvement of the manufacturing process. Honestly, OLED's have higher saturation, more vibrance, higher contrast which makes them appeal to human eye but it comes at a cost.
[LG V20 Questions & Answers] Jaws4God:
Oh cool. thanks for explaining that! I am not rooted... 1. too nervous of causing issues after root .. 2. mine isn't rootable (on most recent security patch)..

so is there anything I can do to help with the blue output?

yeah that seems to be what i've read too... I just typically keep my phones for a while and burn in or ghosting worries me...
[LG V20 Questions & Answers] Sadistic_Loser:
Using root right now and I have taken my problem away with these settings. Here's what I did to fix it

=======================================:

1.Install Kernel Auditor from the play store.

2. Install the MK2000 kernel and aftwerwards wait 5 minutes for the phone to cool down.

3. In KA, Grant Root Access and go to the screen setting.

Type These Values:

======================================:

Red: 240

Green: 245

Blue: 256

Minimum RGB Value: 40

Saturation: 45

Screen Hue: 1532

Screen Value: 120

Screen Contrast: 140

You don't need to use all these settings, I found that lowering the screen value a bit can/maybe will help get rid of screen ghosting.
[LG V20 Questions & Answers] dark_prince:
I actually had to turn the RGB down to 230 230 and 210 for the retention to completely go away. I put the saturation up a notch to 50, Screen value and contrast both sit at 135 and Hue is at 1520.

I'm wondering if there is a way to turn off the keypad light.

The keypad light only makes sense. I know you can dim the display backlight (a registry change) and that helps a bit, but it would be even better to turn off only the Keypad.

My device is a Trinity but I guess a standard registry hack could exist.

I've searched around and haven't found anything. Any help is appreciated

go to pocketmax.net and look for the keylight version.

[T-Mobile Samsung Galaxy S6] ashal:
I had gotten a T-Mobile Galaxy S6 off ebay (refurbished), and I'm not a US resident. The phone and network worked perfectly fome until today, two days after the nougat update, the phone automatically restarted and said that my device is network locked and it can be unlocked using the Device Unlock app. Now when i opened the device unlock app it stated that my device is not elegible for unlock. What should i do now? There is no chance of me going to US or any way tgrough which i can send this phone back to US. Is there ANY possible way in which this can be unlocked? Additionally, the IMEI has changed I guess, the IMEI on the back is different from the one in the *#06# menu. Is there any way to restore the network on this phone or am i stuck with a $250 brick?
[T-Mobile Samsung Galaxy S6] Katybbbb:
Same thing happened to me. I know the person who I bought it from, she has called tmobile and requested another unlock to be sent to the phone, aftet 48 hours they just sent an email saying the device can only be unlocked through the app. Have you found any resolution? I'm thinking we'll have to downgrade the software somehow.
[T-Mobile Samsung Galaxy S6] ashal:
First check your IMEI if its changed you'll have to get it fixed by Z3X box, I got my phone fixed through Z3X box, you can't fix it yourself, and after the repair I had to stay on Marshmallow as the latest update at that time (a month ago) didn't support Nougat. Only unlocking the phone won't fix your issue, it'll keep showing (Searching) in the network name.

[MTCD Android Head Units General] solmer:
Hi! Confirmed, I've upgraded to PX5 (JY UL135). Flashed KD2.40 over JY 2.06_2 then flashed HA 2.52 and everything is working as it should be. Thanks for your work. :)
[MTCD Android Head Units General] nadkp:
I can confirm a cross compatibility as well.

My Unit is a xtrons device with die MCU firmware GS 2.43 and yesterday i did flash the HA 2.52. But be sure to save your mcu config

first

. Otherwise the hardware buttons won't do what they were supposed to do. But after flashing the firmware and restoring the config, everything is back to normal.
[MTCD Android Head Units General] typos1:
To make it easier to re-apply the settings, you can use the mcu.cfg function and flash it with the MCU, just in case anyone didnt know.
[MTCD Android Head Units General] f1x:
Some time ago I tried to investigate what actually those abbrevations mean. In my understanding GS, JY, HA is related to the canbus profiles, not directly to the reseller. It seems to be reasonable because MCU has really tiny flash capacity and add all canbus configurations to one chip would be impossible.
[MTCD Android Head Units General] typos1:
No, you are wrong there - the letters very definitely relate to the manufacturer, NOT the CAN Bus profiles KLD = "Klyde" KGL, = "Kai Ge Le", JY = "Joyous" etc, this has been established for years.

The seller has NOTHING to do with the software at all.

The CAN Bus profiles are named in factory settings

On MTCB/C headunits there was a slight difference in the code between MCU types so they were not interchangeable (apart from BN and HA), it would seem that on MTCD units there is no such variation in the code.
[MTCD Android Head Units General] SpeedyCarv:
Does this also apply to LM_ (Erisin) MCUs?

I have a Erisin 5048 HU with MCU 2.41_1. Does anyone have any experience in flashing a different MCU to a LM_ type MCU? I´m worried to brick my HU if a flash a higher HA_ version.

Any info would be highly appreciated.

Greetings

Speedycarv
[MTCD Android Head Units General] typos1:
There are no "Erisin" MCUs - Erisin are a seller only, they sell units made by several manufacturers. You have an "LM" unit.

I would stick to what [MENTION=4974080]marchnz[/MENTION] has tested already, although having said that, on the MTCB/C units if you flash the wrong MCU you can simply flash the correct MCU to correct it, cant say if its the same for MTCD units, up to you if you want to risk it.
[MTCD Android Head Units General] SpeedyCarv:
My level of knowledge has not grown in any way after reading your post. :rolleyes:

Thank you anyway..
[MTCD Android Head Units General] typos1:
Maybe read it again ?

Basically, you could risk trying it - MTCB/C units can be restored if the wrong MCU is flashed, maybe MTCD units could be restored if the wrong MCU is flashed also ? But maybe not, so that is your decision whether to try or not.

Otherwise stick to what [MENTION=4974080]marchnz[/MENTION] has said and do not try it.

And your unit is NOT an "Erisin" unit, they are sellers and sell units from many manufacturers, you have an LM MTCD unit.

Cant make it any clearer than that. :)
[MTCD Android Head Units General] SpeedyCarv:
Not necessary to read again. I already knew that. That's what i tried to express in typing "my level of knowledge has not grown" Sorry if i write misunderstandable, i'm not a native speaker (German).

Thank you again for your time and patience
[MTCD Android Head Units General] Wout2426:
Can you explain me how ? Do I put the mcu.cfg file with the new mcu in the root of gps SD ?

In factory settings I see only the option to export, not to import. Or did I miss something ?
[MTCD Android Head Units General] typos1:
Thats correct, just put the mcu.cfg file on the SD card with the mcu.img.
[MTCD Android Head Units General] marchnz:
Or, once mcu has been upgraded, you can remove the mcu update (.img) from the root of the gps card and apply the config (.cfg) on the root of the gps card separately - by running the 'upgrade MCU', it will see .cfg file and apply it.

Update for 800x480 users who update to the latest MCU - you must also apply a dmcu.ext

DMCU.EXT details

[MTCD Android Head Units General] screwey:
KD --> HA for 800x480 Screen

I have had quite an experience over the weekend, but am able to report successfully updating a PX3 MTCD_KD unit to a PX5 with the HA2.52 MCU Code.

For those of us with 800x480 screen sizes, as now noted in the main thread, we need to create the dmcu.ext file with the appropriate screen size to be flashed with the dmcu.img file.

Just a note that if you run across the issue of not having the appropriate resolution; don't freak out.

One interesting note I hadn't mentioned before is that after the PX5 started thinking it was 1024, I replaced it with the PX3. The PX3 booted thinking it was 1024 also. After reverting the PX3 to 800 (flashing with screen:3), I replaced the PX5. The PX5 however, did not revert back to 800, but remained at 1024. The PX5 did not revert back to 800 until after I reflashed the MCU, specifically stating it was to be 800 (screen:1).
[MTCD Android Head Units General] 1-2-Hak:
So I tried HA 2.52 on Xtrons TB706APL

I get the following error on reboot.

After I update from dmcu.cfg it goes away but if you go into factory settings and change anything it comes back.

I also didnt see the option for the shutdown that this mcu is supposed to have.
[MTCD Android Head Units General] Bose321:
I assume you mean "dmcu.img" and "dmcu.cfg"? That's how my downloaded img and backup cfg are called.
[MTCD Android Head Units General] typos1:
Yeah, thats right - the "d" is just there to show its an MTCD MCU not an MTCB or MTCC one.
[MTCD Android Head Units General] screwey:
The shutdown option is under System Settings --> extra settings. You wont find it in the factory settings. Just FYI.

Which dmcu.cfg did you use? I might be wrong, but it seems to me it might be dangerous to use different dmcu.cfg files with different versions of the MCU Code.

Hi

Just installed GS 2.56.1 on my TB706APL, no problems, only issue are until now when I reboot my unit all the radio stations are gone and need to be installed again. (never noted that before)

One good thing are that I have had some issues with Goggle Map freezing after new MCU Goggle Map are running perfect. Except that I have not discovered any big changes or issues compared to the old GS MCU

XTRONS TB706APL

MCU GS 2.56.1

[MTCD Android Head Units General] Bose321:
Thanks, sounds good. I believe the radio stations not saving is a ROM issue that I've read multiple times. I'm still on the 2.0 version of the ROM. I'll try this MCU soon.
[MTCD Android Head Units General] meauses:
On the 2.43 mcu I had one phone call which had pretty bad quality. Today on the 2.56 mcu i had a phone call which was of a lot better quality. So maybe they made some improvements on that part. In other topics i see similar experiences on that part.
[MTCD Android Head Units General] Bose321:
Without or without an external microphone? 2.56 GS?
[MTCD Android Head Units General] meauses:
And today Xtrons announced Android Nougat 7.1.1 for their head units on their Facebook page. Wasnt clear if that would be available for all units, px5 or others....

---------- Post added at 09:17 PM ---------- Previous post was at 09:16 PM ----------

Without, just the mic on the head unit.

Im looking for an external mic, but i want to be a 100% sure that that will improve the quality further, and make sure people can hear me better.

Too bad I cant use the already available microphone on my Ford Focus 2 phase 2 :(
[MTCD Android Head Units General] typos1:
Think I said this before in this thread or one if the other (four !!) RK3368/PX5 threads, but the BT issue sounds like the internal and external mics are wired together like on the MTCB/C units and also the motherboards are the same for all MTCD units, or at least they can all take either RK3188, RK3368 or Intel Sofia, so its worth searching the entire MTCD forum to see if others have had similar problems, has anyone done that ?

You mean other MTCD forum threads not necessarily RK3368/PX5 ones ?

Xtrons have probably just started selling the RK3188/PX3 with 2Gb RAM and N, like other sellers have been for a few months.

Have you tried using your OEM mic ?
[MTCD Android Head Units General] meauses:
Well a.o. the topics about the bluetooth echo and also where the hotaudio 2.56 is discussed. thats where i read something about improved experiences with the bluetooth/mic echo.

I have a Ford so the mic doesnt have like a jack plug as far as i could find. Unfortunately the head unit / canbus is not compatible with Ford SYNC, which would support the built-in mic.
[MTCD Android Head Units General] syk02jcb@hotmail.com:
I have wired the HU to my oem mic in Ford (Mondeo 2009). I have connected it to the lock connector attatched to the BT module located in dashboard above glove compartment (using a 3,5 jack with open end wires direct in to the pinholes in connector). In my case its pin 3 (+) and 4 (-). With both internal and external mic it's echo, but i have put a tiny black tape over the int mic hole, and the echo is gone (also testing [MENTION=7621504]f1x[/MENTION] echo solution, right now i'm testing the "c" alternative).

The quality is way better with oem mic, i think the location in the roof is a big part of it (dont need to speak in direction of HU)

I'm on malaysk v4 and MCU HA 2.56
[MTCD Android Head Units General] meauses:
That is very useful information, thanks a lot. I have a Ford Focus from 2009 btw.

When i get in some of the stuff i ordered on aliexpress for my car and going to install it, i will have a look.

Would you happen to have any pictures of it when you installed it?
[MTCD Android Head Units General] syk02jcb@hotmail.com:
Didn't take any pictures, unfortunately. But its lots of guides to do this. The glove compartment is four screws in front and two bolts inside. Once the glove compartment removed, the module is easy to feel with hand under dash, it is fixed with a bolt in centre. Once getting it out you loose the lock-connector and pin 3/4 is numbered. In my case the module isn't used anymore, so i left the connector with the mic wiring unconnected to the module (sold it for around 150 USD, it was the kind with usb and a2dp)

I also mounted a switch in the glove compartment making ACC-Power on without ignition. My Ford turns off ACC-power when opening front door, sometimes i want the HU to continue playing for my kids when i leave car (without the car running or ignition on)...

[MTCD Android Head Units General] typos1:
It sounds more and more like the same as MTCB/C units - the mics are wired together causing and echo, removing a capacitor separates them and stop the echo, then the built in one works for google now and the external for phone.
[MTCD Android Head Units General] marchnz:
In an mtcb and mtcd unit, its a matter of removing a wirelink/zero ohm resistor or desoldering internal mic. Halfnof the issue is the rubbish internal mic and placement/hole.

Sounds easy enough. Do you have more information about this?

[MTCD Android Head Units General] Sventastic:
my Device was running on KGL v1.92a with PX3

I changed the SoM to PX5

and installed Malaysk ROM.

I tried to update the mcu to KGL v2.54

the flashing run fine, but at the end there was the very nice "Version Unmatch -01" message...

Flashing back to KGL v1.92 was not possible.

aborted with message "MCU mismatch".

After i run over this Thread I started to flash several mcu images which are mentioned as "maybe compatible".

At the end the error was gone with KD v2.40.

But I wanted to double check.

So I flashed KGL v2.54 again - negative result (Version Unmatch -01)

back to KD v2.40 (everything ok)

then tried version HA v2.52 - negative result (Version Unmatch -01)

Back to KD v2.40 (everything ok)

after the first error occoured I flashed all following without dmcu.cfg.

so not all devices seem to be cross compatible.
[MTCD Android Head Units General] typos1:
Youre not in a "PX3/5" thread, youre in an MCU thread - MCUs are the same, regardless of processor type - the MCU is on the motherboard, its separate from the SoM.
[MTCD Android Head Units General] OldRon:
Good to know, since I run a KGL unit, too.

I also tried to upgrade from 1.92 to 2.54 and got the same failure... So I will have the HA ready when my PX5 upgrade arrives :)

[MTCD Android Head Units General] Sventastic:
be careful!

I run on KD 2.40 now, not on HA.

I had to re-assign all panel Buttons in factory settings.

So a compatible USB keyboard and mouse may be helpful.

Oh... I overlooked that... Well at first I will try the KGL again, maybe I had a bad image or a badly formatted SD-card...

Thanks
[MTCD Android Head Units General] Sventastic:
Never heared of CHS.

I suggest you contact the seller ask for update because of problems.

usually they provide the actual version matching your system.

don't tell them what you did exactly, just some bla bla that the system has problems.

alternative posability: try out different type of mcu versions... maybe you are lucky and one works out.
