Welcome! I bought a DZ7Y-M300S type head unit! Unfortunately, the firmware update failed. Now the head unit is unusable, I probably used the wrong firmware! Can you help me? How to bring up the recovery menu? Can I get a working firmware from you? Unfortunately, the head unit is unusable! Thank you very much for your help in advance! Akos

Vagvolgyi Hungary

The image is now skewed by 45 degrees, so it is unusable! Please help me!

Thank you very much!

Now I want to update any firmware, it says that only firmware after 2022-07-02 is possible! Could I get a good firmware with a more recent date?
[FYT Android Head Units] Specy01:
I'm sorry I didn't think about putting the language of the car radio back in English before taking screenshots, also because I believe that the icons are the same for all languages. However, I apologize, I am a guest and for fairness I should have done it anyway. Unfortunately now I'm at work and when I go out I won't have time. I will be able to do it tomorrow in the early afternoon. I will edit my previous post with the wording in English. I apologize again
[FYT Android Head Units] Tweak-NL:
I think you could use the same firmware as i have.. But now it wont boot right? So putting the firmware on usb wont start the upgrade i think. Maybe someone can tell you how to fix it. (and maybe i could provide the firmware)

I got the M300S to but the 8 inch version. And why u tried other firmware because of problems?
[FYT Android Head Units] deejayold:
I accidentally upgraded to the 8 inch version instead of the 7 inch version! Any firmware would be accepted, the USB firmware update works, but I can't go back, since the firmware I installed is dated 2022-07-02. You need a newer one or a downgrade! I don't know the downgrade solution!
[FYT Android Head Units] deejayold:
I had no problems with the original firmware! I just wanted to update! Since I put the latest firmware on it (only the 8-inch one, not the 7-inch one), the image is turned 90 degrees to the right and is unusable! I should restore the original firmware! But how???
[FYT Android Head Units] surfer63:
On 4pda they released a modded kernel update that will disable this option. Then you can again flash whatever you want.

If you had read the "VIII. Flashing a Full firmware, an AllAppUpdate.bin or a new system/kernel/core from another reseller" in post #2 of the General FYT based Spreadtrum uis7862 (unisoc ums512) - Q&A, Mods, tips, firmware, you would have seen that that is the first point I mention when you flash "something else FYT" to your unit.

Simply write a script to set the property to the correct "ro.sf.swrotation=xy (values 0, 90, 180, 270)"
[FYT Android Head Units] deejayold:
I cannot find the modded kernel update in question on 4pda… would you be so kind guiding me to the git link or the forum link, please? Many thanks!

Or perhaps enjoy taking the time to solve your own problem that you currently have and then sharing the results and steps here.
[FYT Android Head Units] Tweak-NL:
What is that for a response? Flashing a radio like this is peanuts. Put the files on a usb stick/drive and there it goes.. If something goes wrong then you need more 'skills' to fix it. So i think it is not so strange to ask for help?
[FYT Android Head Units] surfer63:
Yes, it is strange. Asking for help is ok AFTER you did some reading. He obviously didn't do that. First read, then ask for help.

Hi.

I have medeke 6GB/128GB installed in Kia Cadenza Premium with OEM AMP.

Previously I had issues with sound quality there was background noise increases with RPM acceleration.

I tried every thing finally I replace the canbus and the noise disappeared.

The old canbus was from Simple Soft HY-SS04 and all functions were working.

The new canbus is Raise and is working OK except that I can't control the sound volume it is fixed at one level.

When I change the canbus setting to NO AMP the volume become adjustable but the sound volume is very low compared to AMP.

Any idea how to solve it?

I notice also the new harness doesn't have connection for AMP-CONT wire int HU compared to the old one. Is it OK?

Appreciate the help.

I'm considering to buy this one as well from Mekede: some stupid question, do they ever participate in AliExpress sales? I had the past experience, that on AliExpress there are many sales. But those are usually the bigger brands.

Also is Mekede the cheapest to buy this FYT UIS 7862 device? My requirement is that it ships from Poland, or any other country within the EU. As above € 150 it would be troublesome with the taxes.
[FYT Android Head Units] bovcan:
Aliexpress sales? They have quite a big discount and it should be shipped from Poland. I just placed an order for M700S.

https://www.aliexpress.com/item/1005002137438718.html?spm=a2g0o.store_pc_groupList.8148356.8.169233bdiDsP30&pdp_npi=2%40dis%21EUR%21%E2%82%AC%20157%2C91%21%E2%82%AC%2085%2C27%21%21%21%21%21%402101d91e16598063048723250e154a%2112000028664984631%21sh
[FYT Android Head Units] DexterMorganNL:
Yes starting from 22 of August: I believe Mekede doesn't participate in these sales, but you are able to use AliExpress Coupons. I received a $ 5 coupon which I can't use on the moment.

Mekede only has an $ 2 coupon: not sure if I can combine both though. But yes price is already quite good, considering they ship from Poland.

Hi guys, can someone guide me how to connect the reversing camera to MEKEDE M500s unit?

So far i did this:

Is this correct?

Other side:

The black wire should go to any metal part of the vehicle?

Does the red wire remain unconnected?

here theirs documentation:
[FYT Android Head Units] daviddosa:
From the camera, you have a yellow and a red connector. Yellow has to run all the way to the headunit. This is your video signal.

The other one is the actual power. There should be 2 wires on this, a red and a black.

Red connects to the other small red cable coming from the yellow one, like on your first picture, but it should be on the other side of the cable. Both sides should have a small red wire.

Black wire connects to ground. This can be a clean metal bolt. You can strip around an inch of insulation, loosen a bolt somewhere, wrap it around and then tighten it back.

Alternatively, you can connect the red wire to your reversing light. I've connected mine to the reversing light and it's ground. Turns on when you put it in reverse and the light turn on. Takes around 1.5-2 seconds. The reversing light should also have a ground wire, you can join your black ground wire there.
[FYT Android Head Units] OG_Seat:
I'm fammiliar with the reversing light method. But in their documentation it appears there is another method without connecting the red wire to the +12V reverse light. where do they want me to connect the red wire ? A3/ACC? what is it?
[FYT Android Head Units] arca114@gmail.com:
See this image friend.
[FYT Android Head Units] marchnz:
Find an experienced installer?
[FYT Android Head Units] Specy01:
I have the M700S and a rear camera. In most of the posts and of the videos I have seen, it is suggested to make the links as explained daviddosa.

So I made the connections as explained by daviddosa regarding the red wire of the video cable (ie the one where at each end there are yellow rca connectors). The power supply of my rear aftermarket sensors is taken from the reversing light cables. So positive and negative sensors (red and black cables respectively) are connected to the positive and negative of the reversing light, respectively.

So I made the connections as explained by daviddosa regarding the red wire of the video cable (ie the one where at each end there are yellow rca connectors). The power supply of my rear aftermarket sensors is taken from the reversing light cables. So positive and negative sensors (respectively red and black cables) are connected respectively to the positive and negative of the reversing light.

So the links are made as explained both in the various posts and in the various videos and also on the instruction booklet of the rear camera. But I had a problem: the sensors were always powered and sounded all the time while driving when crossing other vehicles. I then disconnected the red cable (+12V) from behind the M700S and now everything works fine.

This is my experience, hoping it can help someone.
[FYT Android Head Units] albertron:
Having the same price, is mekede or navifly better?
[FYT Android Head Units] Specy01:
I think they are the same thing. I took the Navifly only because in the chat my questions were answered much faster than those of Mekede. Mekede, between a question and the answer, more than 24 hours passed

Hi Guys,

I recently purchased this MKD M600S and having some issues with it lately, hoping to get some advice from an able person please.

1. The system keeps having me select the default launcher, I searched and searched but found nothing that could help me have the system remember once and for all the default launcher app. I even bought pro launchers and nothing, makes me choose the default launcher every time I hit Home button or after unit restart.

2. In the unit's app store there are 3 updates available, I'm only able to download and install the canbus update, for the 2 other (see attachment) keeps on saying "download failed"

Previously to posting this reply I have searched on the forum but was unable to get some information or perhaps I may have missed it.

I'm begging for some help here guys, thanks for all your input.
[FYT Android Head Units] arca114@gmail.com:
The other options don't even update, I don't know why they leave an App that is useless..
[FYT Android Head Units] Bitza37:
whilst I do appreciate you taking the time to respond, that is far from being an useful information or an information at all, my plea had 2 points, you responded to neither one.

again, thanks but I would value applicable information not spam responses.
[FYT Android Head Units] daviddosa:
There's an app which can bring up the original android settings.

Take a look at this thread's first post, at the bottom, called "Android Shortcut Settings": https://xdaforums.com/t/general-fyt...unisoc-ums512-q-a-mods-tips-firmware.4396339/

Use this to open up the settings and set the default home app, like you would set on your phone. (You can search for "default apps").

I wouldn't bother with updating those apps, I haven't noticed anything different after I updated mine.

I was using my phone's hotspot to share my internet to the headunit and I was able to update them. If it's not working, try restarting your unit, then trying again. (You can do so by pulling down the notification bar and select Reboot).
[FYT Android Head Units] ziddey:
@Bitza37 I saw the same behavior with the default launcher constantly resetting. Changing the config.txt file may help: https://xdaforums.com/t/weird-launcher-behavior-on-uis7862-machine.4479071/post-87315929
[FYT Android Head Units] Bitza37:
thanks @daviddosa, will give this a try today and also thanks @ziddey - I will give these options a try. Today it was just a mess of a thing, now instead of having me choose the launcher it wanted to combine 2 of them.. jeeeeez, talk about going haywire

Hi all,

I have been searching for a solution but don't seem many has this issue.

For my set, even if my phone mobile hotspot is turned on, I always have to access the wifi setting to allow my headunit to connect. Else it refuse to auto connect even if the headunit wifi is turned on.

Not sure if anyone has this issue and resolved it?
[FYT Android Head Units] Bitza37:
Hi All

@daviddosa @ziddey @Pavel-71 - thanks for all of your input - in the end the one solution that was able to get it resolved was to flash the unit.

I used @surfer63 instructions on full firmware flash Step VIII. Flashing a Full firmware, an AllAppUpdate.bin or a new system/kernel/core from another reseller

It ended up having better sound, functionality and even got to have wireless android auto (something I did not have and had to use the cable). Unit so far is behaving freaking awesome and hop it stays this way. I kept my USB stick with the files for just in case, fingers crossed it will not happen again.

I could not be more thankful for people that share knowledge and help others!!!!!

@earthtk - If you do not have any help from the reseller you purchased this from just do as I did - this or nothing :)) may help you.
[FYT Android Head Units] albertron:
From the last comments I read here, there are quite a few problems with these units. WiFi doesn't turn on automatically, you can't save a default launcher, and now I find out that Google Assistant doesn't work either. I want to buy a unit, but seeing these problems I'm thinking about it. From what @Bitza37 says, it is solved by flashing a firmware, but I don't understand how they can deliver a new product with many things that don't work.

[FYT Android Head Units] albertron:
I have read that page. I'm not saying it can't be fixed, I'm saying it's unbelievable that users have to fix firmware problems on these radios. That indicates the little quality control that these Chinese companies have, and it does not give confidence to buy from them. If they have not tested the firmware enough to fix their errors, and something as basic as Wi-Fi connecting automatically or a launcher being saved by default does not work, they give 0 trust.
[FYT Android Head Units] ziddey:
Well yeah, sure. But depending on the features you desire, there may not be a better alternative, and certainly not at this price. At the end of the day, it's still worth the compromises for most users here. If you really want to be appalled, check this thread: https://xdaforums.com/t/google-account-hacked-new-joying-head-unit.4257535/

It's certainly inconvenient to use an alternate google account, but there's just too much tied to my main one to risk it.

[FYT Android Head Units] mkb_1989:
Any help guys.
[FYT Android Head Units] marchnz:
Given a quick read through the forums for the various device types, you might have to get in line :)
[FYT Android Head Units] Bitza37:
Hey, yeah so I downloaded the firmware from the "official" website - in my case highlighted below. To download you have to register in the next step, be advised the have limited download, so you'll be able to download one time after which the bottleneck it and want you to pay cause why not, so make sure you choose it correctly.

Than follow the steps as provided by @surfer63 (is what I did anyway) - be prepared tho as this may not go well so make sure to read 10 times before starting the process. I still have my original head unit and with no real solutions from either reseller or manufacturer (both failed to respond to any requests) I was like it's either make it or break it, couldn't care less at this point.

As many saw the units come with issues and people have to fend for themselves as they, the manufacturers, provide no real solutions. This forum here is by far the best solution I have found to start troubleshooting my unit.
[FYT Android Head Units] Bitza37:
I think they are well known for making crap products, or partially crap products, these head units, hardware wise they are the best I found, but they have absolute rubbish of customer support and software solutions.

When it comes to security I chose to create a new account and have a new data card just for the unit, not much of a hustle and with a bit of attention you should not have any worries for being hacked into.

Speaking of potential security risk this was just posted lol

[FYT Android Head Units] albertron:
Just now I was reading those security issues. I wouldn't mind using another Google account, the problem would be with the Tidal or Spotify account, although they can't steal anything from those music accounts other than access to the account itself. It is true that for the price of these radios there are no alternatives. I guess you will have to resign yourself and try to fix those problems yourself that they have from the factory. Thanks!

Today I recived Mekede M700S, so far everthing is working. Must say, what a difference, before I had PX3 7".
[FYT Android Head Units] DexterMorganNL:
The way I understand is, that actually 99% of the users have no issues whatsoever. Because it they would, than these Chinese companies would already cease to exist. And I believe for most people, the firmware is actually okay.

It's just that people visiting XDA like to improve their device. That doesn't mean all users are having issues. Most people wouldn't even bother changing the launcher.

I ordered a Mekede M500s today, I'm hoping to receive it soon. Currently I have a Quad-Core FYT unit, which does its job. Just It's a bit slow, so I wanted something faster.
[FYT Android Head Units] Tweak-NL:
@Pavel-71 today my radio changed back to a UI i dont want to use.. Should removing the others i dont want solve that to? It happened 2 times in a row. I like the default UI with google maps on the home screen but that gives problems when opening google maps. So i changed to a simple UI that was also installed.
[FYT Android Head Units] Tweak-NL:
I wonder if you can find out what they mean in the manual. I had the same 'problem' the wire i tried was always giving 12v and most rear camera's have IR led's so you know what the problem will be.. with a permanent 12v.

My previous radio was connected on a different way that worked perfectly. I did not even use the ground for the camera. It was getting the ground from the yellow RCA connector. Let me try to explain, when u put the car in the reverse the canbus box is picking up that signal from the BCM? And the only thing that the canbus box does is giving 12V on a wire that goes to the radio so the radio knows to switch for the rear cam.

You can use that 12v cable for powering the camera, that worked perfect for me with previous radio and also with the new one. But with this new radio i needed to cut the wire so i could connect the 12v. If u want to know wich wire let me know. If i am correct look at the plug that goes in the radio (black connector) there is a big black wire (ground) from there it is the 3rd wire on the same row.
[FYT Android Head Units] Tweak-NL:

I have finally bought an rcd330 taking advantage of aliexpress offers and coupons. It doesn't have Android, but it does have Android auto and it integrates well with the VAG group (I have a skoda Rapid). I liked the idea of having an Android unit, but because of the ease and speed of use for both me and, above all, my girlfriend, I think I've done well.
[FYT Android Head Units] DexterMorganNL:
Nothing like that available for my car: but I'm sure whatever kind of bugs, are in these Android head-units. With the help of an active community, which is the case with these UIS 7862 device's.

Than I'm sure most issues can easily be resolved: one of the reasons of ordering the Mekede M500s, was because it has a lot users here. And there is also TS10 which is similar specs, but that device looks even more buggy.

[FYT Android Head Units] surfer63:
The FM widget is of course based on your radio, not on the HAL9K launcher. The direction is based on what your navigation app can show, which in this case is probably Google Maps or Yandex Navigator.

If you really want a freely modifiable launcher you should go for FCC launcher or CarWebGuru or Nova. For complete freedom and "design" options you need the paid version of all.
