Dont be afraid to flash the whole thing. Nothing bad could happen.

I managed to end of at no booting. I think I faced the worst case scenario.

Just find the firmware for your head and other files. And repeat my steps.

The link I sent you has also firmwares for your unit. You gotta test them all...

Папка из Облака Mail.ru UIS7862_UMS512_UIS8581A _SC9863a

Check all the folders and download all FW for you head. If they will install in Russian language use google photo translator to navigate the menu to switch back to english.

Can anyone help me out to fix my device? It is 12.3, BMW.

I am willing to pay someone to assist me.

Thank you.

I do not have firmware!

Reseller is broken and out of alliexpress,
[FYT Android Head Units] surfer63:
The link to firmware is mentioned in the first topic of post #2 of this thread.

Hey all. Quick question, if you don't mind — how much space is (typically) taken up by the system + default apps on these units?
[FYT Android Head Units] sk8xnick:
13.5 gb for my

I have 8gb + 128gb and with carplay it still sometimes slow.
[FYT Android Head Units] InElement:
Thanks! Are you on an 8581 or 7862 unit?
[FYT Android Head Units] sk8xnick:
7862. And feel good now. I have accord 2008. And it feels like im in a new modern car lol. Decided to not to buy MB C350 2015 and drive accord for a few years more.

The only issue is that wallpaper is cancelled after every relaunch. And I cant custom set up steering wheel buttons.
[FYT Android Head Units] InElement:
I'm in a similar boat. Would like to go electric, but decided to stick it out with my existing (antiquated) ride for a couple years longer. Appreciate it — thanks a bunch.
[FYT Android Head Units] surfer63:
Then don't use carplay or Android auto.

If you have a 4GB or more unit, a 7862 it is very fast. The fastest you can get.

Only making it a Carplay or Andrpid Auto emulator does indeed makes it slower: 3GB, 4GB, 6Gb or 12Gb or whatever. Why buy an expensive unit which can do everything very fast and then turn it into a slower emulator?

I have a 4GB/64GB unit is and it is very fast. From the 64GB 12 GB is taken by the system, leaving 52GB "free".

Then read the forum.

Setting up steering wheels is at least a 100 times mentioned and depends whether you have a Canbus or not. And in case of a Canbus you have by default no alternate settings as it is hardcoded. In that case you have two programs to change it. @seb21 modded com.syu.ms or my FytHWOneKey.

Which wallpaper is lost after relaunch? Ther unit one or the Carplay one?

And what is relaunch? relaunch of carplay? coming out of sleep of the unit? or after a reboot?
[FYT Android Head Units] WeelkooPL:
Hi! I just bought FYT unit with UIS8581 unit for my Lexus and noticed one thing - the amount of free/available RAM is very low - my unit is claimed to have 8GB of RAM and CPU-Z is showing the same amount but only 7~8% is free (after restart with no extra apps opened). Is it normal? Can anybody check free amount of RAM on Your devices?
[FYT Android Head Units] Teslic:
What is UIS number?

If you mean processor it is cortex a55 (9863)

I will attach, photos of my motherboard.

Device is in a boot loop. It shows logo and then restarts itself.

It broke during firmware update, because I did not check swipe data on update.
[FYT Android Head Units] surfer63:
Via Developer options you can see the amount of RAM used, just like CPU-Z, but if you click on it you can see which programs use how much memeory in the past xxx

What if you simply try to flash an update again. Now with swipe_data.

Ans also read post #2, especially section IX.

I guess @sk8xnick means the Fyt manufacturer id.
[FYT Android Head Units] Teslic:
That update was carried out from settings menu that I cannot access now, cause device is in bootloop
[FYT Android Head Units] surfer63:
FYTs do not support upgrades from the Settings menu.

So I checked back on your first post.

You don't have a FYT, but as this is the FYT forum I assumed you have a FYT.

I am afraid nobody in this forum can help you and certainly nobody with a FYT has your firmware.

You should try in the General head units forum.

[FYT Android Head Units] sk8xnick:
As I mentioned I have 8gb ram + 128gb and it still slow somwtimes to me. I mean sometimes it take 0.8 seconds instead of 0.2 seconds to open an app. Navi has 0.6 seconds delay.. This is very slow to me nowadays.

Highly appreciate the info on steering wheels controls. I spent around 40 hrs browsing forum but never found the answers. Will try to find these solutions.

Unit wallpaper. After I turn off the car, turn it on, wallpaper is back to stock. Tho I uploaded my wallpaper picture into the Pictures folder.
[FYT Android Head Units] sk8xnick:
UIS - head unit (model number) number UIS 7862 or whatever.

I think they meant Available in usage RAM 8% of total. Therefore the head is using 8% of total capacity.

Its easy to test - run all the apps with navi and whatever you have and see the difference in the RAM number.
[FYT Android Head Units] sk8xnick:
I'd start to install every single firmware one by one untill I hit the jackpot. What I did to my head a few weeks ago. It resulted in less time spent that trying to find a solution online.
[FYT Android Head Units] surfer63:
This is due to the EMMC "harddisk". Modern phones use UFS. That is so much faster than EMMC. That causes the startup delay.

And also: 8 GB allows you to keep apps longer in memory before they are swapped out for a new app. But the unit firmware is still optimized for 4GB and then rolled out over all units. That is where @mariodantas kernel MD-Edition helps those users on 6GB+ units. It has memory management that makes better use of memory if the unit has it.

-----

If you had the wallpaper not on internal memory but on USB, that could be a reason. Upon deep sleep but also cold reboot, the system is up-and-running and only then the USB-devices are mounted: much too late for the wallpaper that the launcher wants to load. Now in the Pictures folder inside internal memory it should correctly work.
[FYT Android Head Units] mariodantas:
Hi fellows, I saw somewhere (don't remeber exactly where) that sometimes Wifi 5GHZ and bluetooth cause issue ?, I mean I can't connect to a 5GHZ network, but randomly and after passing days searching the cause i didn't find anything.

Can anyone here help or did anyone here heard about these BT/WIFI issues ?

Thanks in advance !
[FYT Android Head Units] Matt Devo:
BT operates at ~2.4Ghz, can overlap with some WiFi channels in that range. 5GHz is no problem

3 -NAVIGATION
[FYT Android Head Units] j0hn83:
You would add that line to your config.txt file.

Post #4 in this thread shows you how to backup your current firmware including your config.txt for your head unit.

Once you have backed the unit up you can simply edit the config.txt as you like.

Then put the new config.txt on a USB flash drive along with your current lsec6315update (or lsec6316update) file and insert in to your head units USB port and it will flash.

Hello!

I bought a MEKEDE m6 pro. I have several problems.

1. Unfortunately, it does not work with a Hungarian LTE SIM card. In question 23, I read that it can be made functional by changing the IMEI number. Can this work even if there is no field strength signal?

2. My car is a Peugeot 308 Hatchback (year 2007). A Raise RZ-15 CANBus adapter (fw: 04.23) was added to the head unit. The steering wheel switches work, but I can't set the clock on the center display. The climate feedback doesn't work either. Is this adapter not fully compatible with my car? Has anyone managed to find a setup that makes these functions work, or does it require a different adapter? Which other type would be suitable?

3. My cell phones open the 5 GHz mobile hot spot on channel 149. Unfortunately I can't join them. Is there a solution for this, or will 2.4 GHz remain?

Thanks for the help!
[FYT Android Head Units] surfer63:
1. You can change the IMEI but I have no idea about your field strength signal.

2. Search the forum on Peugeot 30(0)8. There is a thread "Problem with Canbus Simple Soft XP on Peugeot 308" from @Specy01 . Multiple CANbusses are discussed in that thread.

3. Search the forum. What's more: search this thread! See post #2087 and around it.
[FYT Android Head Units] Specy01:
In answer to your second question/problem: I have a 2012 Peugeot 308, I have here been the Canbus XP because the Canbus Raise supplied with my M700S NaviFly did not give me air conditioning feedback and some steering wheel controls did not work.

With this Canbus things have improved but I had to play with the choice of the type of machine to be set for the options of the canbus, in fact the best solution was to set the 408 although I have the 308.te I highly recommend it.
[FYT Android Head Units] darudon:
1. It was not clear from the descriptions that this helps even if there is no field strength display.

3. Yes, I read it. The problem with this solution is that you have to connect to the hotspot with the lower channel first. This is possible at home, but elsewhere it is not certain that if you turn it off, you may not be able to connect again.

The question was, does the head unit recognize the higher channels? Is this capability a feature of the WiFi module, or can it be modified in software?

Thank you very much!
[FYT Android Head Units] darudon:
I read your post about your CANBus problem. Have you changed your adapters several times, is everything fine with XP now? What functions are available? There are no buttons on the central display, the time could be set from the factory radio, does that work for you?
[FYT Android Head Units] Specy01:
With XP everything seems to be fine, certainly much better than the Raise canbus I tried. In practice I have all the controls on the steering wheel that work in the right way, except what the "carousel" does, this if it is pressed in fact, it only switches to Bluetooth calls, that is, from the home screen (or from the radio or media player or from Spotify) goes directly to the Bluetooth app, and if it is pressed again it remains on that app. If I act on any control or physical air conditioning, I see at the bottom of the screen a relative screen that shows the button / command pressed, even the set temperature is shown.

As for the various messages of the on-board computer, these are absolutely not shown on the radio unfortunately. These messages are shown on the original small top screen of the 308 (I don't know the right technical term).

As for the time, I realized that if you set the right car in the canbus menu, the time is almost instantly shown at the right time, while if you change the right type of car the right time is shown after a long time. As for adjusting the time, the brightness of the display (the original small upper one), the language etc, these can easily be adjusted thanks to the "vehicle setting" app. I hope I was helpful, for other doubts ask without problems. As for me, unfortunately for about a month I have a problem with LED daytime running lights that no longer light up during the day with the headlights off. I thought the problem was due to the firmware, but despite installing the latest firmware from Mekede, I didn't fix anything. Surely I should have the ECU fixed by an electrician, but for now I don't want to spend money, so I keep it that way.
[FYT Android Head Units] darudon:
Thank you very much for the exhaustive answer. Maybe I'll give it a try with XP as well.

I've got a new M700s plus with 2k screen, but I have the issue with Wi-Fi. It show Wi-Fi connected but still show the x symbol on Wi-Fi icon on the top right. I tried with many routers but it's the same.

I searched in the forum but there is still a mess. Does anybody know how to resolve this issue.

Thank you.
[FYT Android Head Units] j0hn83:
The head unit simply does not see 5GHz channel 149+

It isn't unique to these units either. There's are millions of wireless devices that cannot see these high channels.

I gave the example of Xiaomi phones as that's what I have and what I have experience with.

Xiaomi phones will use a 5GHz hotspot channel on whatever channel the phones WiFi is currently connected to.

If you Xiaomi phone isn't connected to any WiFi then it uses 149 by default every time and the head unit will never see it.

The only workaround I could find for this was starting a hotspot on the head unit, connecting the phone to it, then starting the phone hotspot.

If your phone insists on using a 5GHz WiFi hotspot with channel 149+ then it is simply best to change to using the phones 2.4GHz hotspot.
[FYT Android Head Units] Specy01:
How do I see which channel is being used by my phone and HU?
[FYT Android Head Units] danilaur:
hi guys, i cant find "settings" to start apps in background?

a launcher can influence the running of some programs?
[FYT Android Head Units] surfer63:
That is because it is no longer allowed to do so after Android 9.

What malware/spam/virus/phishing software did you want to start in the background? (to give you the reason)
[FYT Android Head Units] j0hn83:
I use an Android app called WiFi Analyser
[FYT Android Head Units] surfer63:
I use it too for many years already. Also to find the most empy spot in the 2.4 GHz range when necessary.
[FYT Android Head Units] danilaur:
adguard
[FYT Android Head Units] darudon:
On most phones, the desired channel can be selected in the 2.4 GHz hot-spot settings. I have auto, 1..11 ch options.
[FYT Android Head Units] surfer63:
You can't start it in the background. Some of those programs use a second service to be able to switch to the background and stay in the background.

Ok, @surfer63 , I feel like I'm in over my head with something bizarre here.

I just replaced my Atoto S8 with a new one under warranty (old one kept hard resetting itself and eventually they were nice enough to replace it). So I've been trying to put everything back the way I liked it. Should be easy, right!?

Ugh.

I updated to the latest firmware and then flashed Mario Dante's kernel, but I remember not being fond of the clockwork boot animation it comes with so I decided to try replacing the zipped boot animation folder with a different one for my car (Toyota). I found another thread here with samples of boot animation files, replaced the part0 and part1 folders in the zip along with the desc.txt, and flashed the firmware.

Well, it didn't take. Now my unit doesn't play any boot animation. It shows the startup screen logo, then goes right into the system. Bizarre but ok. I found a zip you had shared here: https://xdaforums.com/t/teyes-cc3.4189041/page-27#post-84711041

you made that a long while back to flash another boot animation, so I tried it. Untouched, just wanted to see if I could get even your animation to play.

I got an error about the update file being too old. So I took the lsec6315update and 7862ksec.sh from @mariodantas kernel and did it again. Still no boot animation. Just plays the opening logo and then stays until the system boots. So weird.

In addition to that, now my whole system is acting funny. The display shut off on me, and the buttons remained lit up when I removed the key. Hit the reset button pin and started over... I'm not sure what I'm doing wrong here but this is so bizarre. And this is a brand new unit! I had my old one working fine outside of a hardware problem!
[FYT Android Head Units] surfer63:
That's not the way to do it, and even if you do it make very sure your create the bootanimation.zip with method=store. So NO compression at all. The PNGs are compressed already.

For a bootanimation.zip you only need the lsec6315update and the bootanimation.zip. Nothing else. I do not really understand which 7862lsec.sh you took and why.

EDIT: That post is old and the script in there is not necessary. I corrected that post. That was how it was done on the Sofia, the PX5 and the sc9853i and I just copied that way of working to the uis7862. Maybe it was not even necessary anymore on the sc9853i.

The bootanimation.zip or a logo.bmp is a separate step in the lsec6315update binary. The 6315_1.zip, flashing, the AllAppUpdate.bin flashing, the bootanmiation and logo.bmp flashing, and finally the lsec script execution are all separate steps.It should not have made a difference either with or with the 7862lsec.sh script.
[FYT Android Head Units] dishe2:
Ok, so perhaps that explains why it initially broke the boot animation (it wasn't using store, it zipped it probably using whatever windows explorer defaults were in play), but it doesn't explain why I couldn't even get YOUR zip to work. I left the bootanimation zip untouched just to use as a control test, and it still won't play.

To be fair, something else has gone fubarred as well

I wasn't sure what I needed so I grabbed those files from @mariodantes firmware. Interestingly, I noticed that even in your zip there is an 7862lsec.sh with the following code inside:

#!/system/bin/sh

#

mount -o rw,remount /system

cp /storage/sdcard1/lsec_updatesh/bootanimation.zip /system/media/bootanimation.zip

chmod 0644 /system/media/bootanimation.zip

printf "Done!!"

printf "Wait for the system to tell you to remove the USB-stick/SD-card"

You're saying I don't even need that?

Meanwhile, I don't know what's going on but my unit is acting very very odd. I don't understand what I did wrong but I'm thinking maybe I should go back and flash a stock firmware. I didn't do a backup. 😫
[FYT Android Head Units] dishe2:
Good news, flashing the more recent firmware from Atoto brought it back to operating conditions. I'm assuming it overwrote Mario's kernel and everything, the original boot animation is back. But the apps I installed are oddly still there. Weird.

I want to install Mario's kernel again but I'm hesitant to mess with it at this point.
[FYT Android Head Units] matrixx1:
Hi all I have an issue with car link app. When I start the car and the headunit hot boots, 7 times out of 10 I have to manually swipe away the car link app from recent menu, otherwise it won't connect to the phone. Once swiped away it opens again and connection is established. My HU is not rooted so I cannot set-up a macro in macrodroid to kill the app once the devices boots up. As Carlink is a system app I also cannot put it to sleep because this (hidden setting under battery) won't show system apps, it lets you only to put 3rd party apps to sleep. Does anyone have any suggestions how I could solve this?
[FYT Android Head Units] surfer63:
No, you don't need it. Just the lsec6315update (or lsec6316update) and the bootanimation.zip in the root of the USB-stick.

What's more: The script is now even wrong and will not do anything anymore. (I will completely remove it from the post).

The first uis7862 came with the old partition scheme. After 1-2 months they came with the new partition scheme (the super-partition) where the system partition can't be made read-write anymore at all.

Hi surfer63,

i tried to use your script to backup my uis8518 unit.

but i got an error during the backup proccess.

/storage/sdcard1/7zzs........ failed

the BACKUP directory do created, and the size of files there is 382 MB.

it it ok? because the 7zzs command failed.

no other errors, this is the only one

also, i have searched online for universal kernel/core for uis8518.

but i didnt find anything... i will appriciate if isomeone here has this file, and can share it here.

Thanks

Hi, can these units output anything other than 2channel stereo via Optical?
[FYT Android Head Units] surfer63:
That's my stupid mistake. The 7zzs is an ARM binary. Your 8518 unit needs the x86 version. I updated the script but forgot to adapt it for the correct binary. Please find attached an(other) updated zip

Hi Harry, that a super idea to backup directly to AllAppUpdate.bin, is it possible to add the "360res" dir ?, conaining the 360View software (on some units) ?
[FYT Android Head Units] surfer63:
Yes, of course it is. I don't have it in my unit, but I can easily add it. I did not even think about that. I saw it already in your universal backup script.

If 7zip can't find it, it will simply skip it.
[FYT Android Head Units] mariodantas:
I this that when we boot with lXXXXupdate file, ,the 360res dir is not visible, that was my problem when I tries with my universal backup script !
[FYT Android Head Units] surfer63:
I didn't realize that, but then again: I don't have it.

Is it a special mount point that first need to be mounted before starting the backup?
