[Samsung Galaxy S7 Questions and Answers] L1feGuard:
has it happened to anyone to fix it? after warming up the screen is fine but when it cools down it still works. help.
[Samsung Galaxy S7 Questions and Answers] dbotop:
Hello,

I have a similar problem, but mine is about three quarter black. I will try to describe the problem in a more detailed way. My good old Galaxy S7 served me well for a couple of years, but recently produced a weird behavior with the display. It started with some flickering and now and then some thin black horizontal lines. After a while the lower part of the display turned black, finally resulting in the lower three quart of the display remaining black.

After a clean swipe of the cache and a factory reset the display became normal again and remained so after a couple of hours reinstalling apps, passwords, etc. Even after a short while standby, the display returned to normal. However after a prolonged standby time of a couple of hours the display became three-quarter black again. A new factory reset resolved the screen trouble, but again after a prolonged standby the trouble reappeared.

To me this does not look as a hardware problem, but it might be a firmware glitch. Has anyone seen a similar problem with the S7 and could it be resolved with flashing the firmware? Any ideas where I can find a reliable firmware version and eventual suitable Android (now 8 installed) version for the S7? Preferable with a decent installation description. Most downloads I have found seem to offer a manual in Sanskrit and are hard to understand for other people than the guy that wrote it.

Appreciating your help.

Greeting,

Dave

[Google Pixel 4a Questions & Answers] kadeta:
Please advise how is it with the speakers: I have google pixel 4a, it plays audio songs from the web or with youtube or mp3 stereo through 2 speakers top and bottom speaker and very loud. However, it plays all ringtones, including the original ones on the phone, with only one speaker, and with a speaker. It should be like this? That's right, or the phone is a complaint. Thank you very much for the advice.

Prosím o radu , Jak je to s reproduktory: Mám google pixel 4a, přehrává audio písničky z webu nebo s youtube nebo mp3 stereo přes 2 reproduktory vrchní a spodní reproduktor a to velmi hlasitě. Ovšem všechny vyzváněcí tony, v četně originálních co jsou v telefonu, přehrává jenom jedním reproduktorem ,a to s podním. Má to tak být? Je to tak správně ,nebo je telefon na reklamaci. Moc děkuji za radu.

[Nintendo Switch Questions & Answers] JCnut:
Hi there! I got my switch modded by someone because I was total noob and wanted to just , pay a guy, get my switch, and do what I wanted to do with it. Anyways, after having my switch for over 2 years now and enjoying it, I decided to install Android on a New/Fresh SD card so I can boot Android on it. So, I had no idea what was installed and from what I gather, I can't load TegraRCM as I have a hard-soldered TrinketM0 chip to skip the JIG/RCM Payload injection step. ... I guess? lol, sorry, I am not very good at this stuff.

Anyways, I have a folder named "0" that it seems the chip looks to and whatever payload .bin I need to use, I need to rename to "start.bin" for the chip to recognize to boot whatever I want. So here's the step by step that I do now. I install the lineage zip from https://wiki.switchroot.org/en/Android/Setup-10 that is explained to me. I also got gapps zip and the joycon zip because the purpose of this is to remote play my xbox (im a nerd...) on my switch and I do all the things correctly and I actually boot in Hekate, I do the Joycon dump, I do the 16gbs Android partition and then when it comes to "More Config" step of booting Android 10 for "Switchroot Android" , this is where I have things not working anymore. I click on it, I hold the Vol+ button and .... nothing loads. I also tried to "Flash" my SD card with this link "https://xdaforums.com/t/rom-unofficial-8-1-switchroot-lineageos-15-1.3951389/" but it seems to corrupt my SD card. I have a 64gb sd card and I tried flashing with the 64gb download and the 32gb download. Also, I should mention I am on a MAC (Please don't start a PC vs. MAC thing). I am assuming I can't load "Switchroot Android" because I need to rename it "start.bin" somehow? When I click on "Switchandroid Root", Hekate IPL logo loads but then, it just goes black... all this is while I hold Vol+ and I have waited for over 2 minutes and it is just a black screen. I am super confused and I asked on a few discord channels regarding this and I was ultimately referred to this forum.

I formatted my 64GB SD Card to Fat32 and also tried formatting it to ExFat just in case.

So heres the resume of what I am working with.

MacOSX

TrinketM0

No TegraRCM/NO JIG

Brand new SD Card

If anyone can help, awesome!
[Nintendo Switch Questions & Answers] ELY_M:
need to use hekate payload. you have to name hekate payload as payload.bin

my android switch have trinketm0 in it.

Bumping this thread. Wondering how I can backup the apps and ROM.

I also want to check dmesg or interrogate hardware in some way to see what radio IC it uses. The manufacturer claims in supports RDS, but the built in radio app not showing any RDS info. Unsure if its just the app, or the hardware. I'm assuming I would have to root the unit to get this info .. if any rooting tools available, would be much appreciated.

Many Thanks :)
[Android Head-Units] Anton TNT:
Search for firmware in this forum by - mtk (device type) A-media 007 (model) android 11

You'll probably find a match.
[Android Head-Units] nevoz:
Thanks for the guidance Anton, but unfortunately such a search returns nothing (except for this thread we are in now..). Sounds like I must have purchased an obscure unit with chips that hardly anyone else has..! If any further guidance to point me in the right direction, would be appreciated.
[Android Head-Units] marchnz:
It's an Odd ball. I've never brought a car without knowing what it was.
[Android Head-Units] nevoz:
It's easy to say that you wouldn't have bought (not brought) a car without knowing what it was, but we don't know what we don't know (also it's just a head unit I bought, not a whole car (?)). You would be way more experienced on what to look for and what should be asked. I thought the specs like ARM etc would be enough, didn't realise that deeper research would have been needed. I can still return it if I'd like to, TBH it isn't a big deal the head unit seems to work well - Google Play, Android Auto Wireless .. working wonderfully. It just would have been nice to root it to enable more flexibility. I assume I can't do things like backup apps without rooting.
[Android Head-Units] Anton TNT:
I didn't mean to search mainly here, expand your search on net there is a Russian forum with updates and firmwares 4PDA, bunch of video files on youtube for specific devices and with links to firmwares etc.

Thanks Anton, I did search Google but didn't find much. I'll check YT / 4PDA, as you suggested. Thanks for the guidance again.

Hi! Are you currently using this device?
[Android Head-Units] TboneL:
I have an A007 (KingPad_SA10_EEA) manufacturer SPRD, brand VastKing. My display is 1280x480. It was made for a BMW E46 but I am going to use it in a Plymouth Prowler because of the size. Anyway, I found that it has a UNISOC UMS512 CPU. Not sure but it maybe a T610. I did have a problem with Zlink v5.2.3 when using Android Auto. It would stop the music when the nav was speaking and never restart. The vendor sent me an update zip file. THIS IS AN MCU UPDATE!!! This updated Zlink to V5.3.72 and now it works. https://wetransfer.com/downloads/d9...825a62dba56f89108144fdff20221009064018/eedc8a This is only good until Oct 16, 2022. Just had to copy the .zip to a thumb drive (Fat32) and insert it anytime and watch for the message quickly appear to Install. I did get it from Alibaba Navifans Franchised Store.

I got this unit, too. Guess there will be some more information around soon since these are new and very fast units on the market. Mine has 8/128 GB of RAM. Don't like the resolution of the 32 band Equalizer and Radio but everything works pretty fast, so its ok for me. If there are more informations around also how to upgrade to a better Equalizer and Radio App, please share your information
[Android Head-Units] Rom80:
Guys, can you show me the factory settings as I have a major problem finding an option to switch off the standby mode? I can drop some screens from my radio if needed.

Brand: Wondefoo 8/128GB
[Android Head-Units] bytechus:
Hello Rom80.

I have the same equipment as you, a Wondefoo 8/128G. In my case everything works fine except that the reversing camera shows the inverted image (the sky and clouds are seen at the bottom of the screen).

If you want to send us the screenshots of all the factory setting screens, there are about 25 images. Or we share the settings configuration file "ZQ_FACTORY_SET". The latter is more dangerous because we can have a nice brick.

Have you touched anything in the settings?
[Android Head-Units] Rom80:
No i dont , i just runs through the all options and didnt find anything that has something to do with standby mode at all. I might be blind and just missed it but i think its just my low skills with new type of the HU with android 11. I go and do screens of my FS.
[Android Head-Units] bytechus:
I agree. I'm also going to make screens and we change them to see. By the way, make a backup copy on the last screen "Setting Export", enter a usb, and select "Export Config", and save it to the USB. That creates the "ZQ_FACTORY_SET" file, which you must save in case you modify anything. I take the pictures and put them in a pdf and we don't exchange them.
[Android Head-Units] Rom80:
Good then. Going do it asap to show you mine settings. Maybe i find the diff. to solve my problem.

So your HU just starts from cold start every time you start the car ? Or pup up quick like from sleep mode ?
[Android Head-Units] Rom80:
Here is mine settings but i would like to know wheter your one puts in cold sleep or not. Mine still pops up as from sleep mode on.
[Android Head-Units] bytechus:
My unit boots fast. If I want it to turn off completely and start from scratch I have to keep the off/on button pressed for a few seconds and the next time it starts from scratch. In yours, does the rear camera give a normal image? Let's see if comparing the two configurations, we solve both problems.
[Android Head-Units] bytechus:
Sorry I couldn't reply earlier. I send you my configuration. Let's see if between the two of us we can solve our problems.
[Android Head-Units] bytechus:
I have only changed the bluetooth microphone that I have put external, in the ARM setting screen
[Android Head-Units] bytechus:
Remember to make the backup of the configuration before carrying out any operation, in a USB formatted in fat32.
[Android Head-Units] Rom80:
Ok i try to pass over your settings but as far as you wrote you do complete shutdown of the HU only with pessing the power button. Its not solving my problem to find the option to let control the HU and switch it off completly. My previous HU has that option turn off the standby mode......

Plus this unit has Fake system installed , pretending to be 11 ... and is 10.
[Android Head-Units] Rom80:
Mine camera was hooked only for testing because i didnt get to it to tear down the 5th door and mount it properly. But when i turn it on. It shows regular image plus 2x guidelines which i need to turn off in basic settings. But works fine to me.
[Android Head-Units] bytechus:
Well, it must be that the Chinese seller sold me a defective camera. I have put its configuration and it does not solve it either
[Android Head-Units] Rom80:
Could be the issue of faulty camera.

Now the issue is whether the radio drain too much battery when car is off. Have to take multimeter and try it through the fuse box how much it takes. Red somewhere that some units doesnt have that option to turn standby mode at all...install new system ? Maybe ?
[Android Head-Units] bytechus:
I don't know if I can help you. Did you connect the yellow cable to bat+ and the red cable to acc+ (positive after the ignition key)? If you connect the two cables to the ignition after the ignition key, the equipment will completely disconnect when removing the key. Although you will lose the memories of the radio. What does it mean that it is an android 11 fake?
[Android Head-Units] bytechus:
On the "can setting" screen there is a "radio switch" option. Have you tried it? It's a matter of testing, if it doesn't work it goes back and if you don't remember what you did, just put the "ZQ_FACTORY_SET" file in the root of a usb and when you enter factory settings it asks you to update. I do not see the battery on the screen, although I activate the option. I see that it works for you.
[Android Head-Units] Rom80:
I think its just radio option as physicall FM radio but i gonna try and see what happends.

Regarding the fake version of android , you may test your one with some Fake test system apps from Google play. Try to download and run it , you will see your real hardware specs same as soft specs....mine is 10 but pretend to be 11. Why those fake systems ? Simple cheatings from the sellers....
[Android Head-Units] bytechus:
Thank you very much, I didn't know that. If his is android 10, mine is surely him too. If you want us to do tests together, don't hesitate to tell me, let's see if we can solve the problems.
[Android Head-Units] Rom80:
Just download the app direct in your unit. It will show you whats your settings.
[Android Head-Units] Rom80:
Here is how it looks like when someone cheating a little....just a little 😂🙊

Android version 10 not 11.
[Android Head-Units] Rom80:
And here are the measurements that i made today. With all down and locked. The draining is too low and looks like it takes only few mA around 12 in standby mode.

Plus few things that take too it makes around 29mA when car is off and the battery is measured within 30 mins distance to let battery calm down.
[Android Head-Units] bytechus:
Phew. You are very advanced in handling electronics. Today I finally managed to reconnect the rear camera but not in factory settings, but in the general settings. But the image is reversed. I think I bought a camera for the front area. I'm going to buy a different camera and try it, because the seller knows less than
[Android Head-Units] bytechus:
In case it helps, I'll send you a video where they do what you want. But in our team I don't know where the engineer mode is.
[Android Head-Units] bytechus:
They won't let me link to the video. If you want give me an email
[Android Head-Units] Rom80:
ok then. Thank you in advance too. It's not a big work to find the energy loss if... but the radio seems that be working well with canbus.

Gentlemen, do you know how to upload an extra bootlogo? Into which directory? in the factory settings I have only one image (internal) and selecting external I see nothing

Hi Guys , i got one unit for my Audi A6 C7 with RMC radio. The android display works pretty fast and i like the display its antiglare with blue filter it seems. Have problem that the units freezes - dont turn on on ignition ON, only for minute or two on ignition OFF. Lost two days figuring the reason. The seller tries to help me but he redirect my problem to his engineers and it takes the time. and now are the holidays in China.
[Android Head-Units] edealcity:
Hey guys, I just got the exact same unit a007, have you figured out the RDS and equalizer options? Also the password to get into factory settings
[Android Head-Units] cobanoti:
try 8888

0000 worked but I’m looking for engineer settings

For engineering menu use password 99992

Has anyone found a way to disable the auto-dimming function when car lights are on?

Due to local regulations, lights need to stay always on and the screen is too dim to be used...
[Android Head-Units] edealcity:
Yes that worked thanks…

Anyone know how to change the screen size on this unit? I’ve looked everywhere and I don’t see any options.. my screen is smaller than the setting I’m getting some display cut off the left side

Hello,

Can anyone please help me with a way to boot into recovery mode my A007 Android 11 chinese head unit (Wondefoo 8/128 Gb) ?

Oh hey, I have this same unit too, was asking about it here https://xdaforums.com/t/wondefoo-8g-head-unit.4563803/post-88269419

It's in my 2009 Focus. Works OK except that it doesn't detect when headlights are on. So display doesn't dim, and panel buttons don't turn on. Does headlight detection work for you guys? On mine the Factory setting passwods 0000 and 99992 worked. CANbus is working for the steering wheel controls.

Also, the factory head unit I replaced was the Sony with integrated 6-CD changer. I believe it had an external mic mounted up by the dome light. I'd like to connect that since it's already mounted, instead of the external mic that Wondefoo provided. Has anyone done this? The Mic pin is not present in the quadlock connector/harness they provided. I've ordered another quadlock connector and pin kit from Aliexpress so I can try to insert the required pin.
[Android Head-Units] Jgn_:
Something wrong in canbus config. is it selected correctly in the factory settings?
[Android Head-Units] Anton TNT:
If your unit has online update , update MCU system and can version.

And set CANBUS settings that works with headlights! If still not working check your lights (orange) wires at the back for misswiring.
[Android Head-Units] highlandsun:
I've checked the wiring already, the orange Illumination wire comes from the CANbus module. I'll try online update again, but I think I tried before and nothing was available.

...

Ok, I did an MCU update to latest version. But CANbus update is grayed out, can't do anything there. Do you think a different CANbus module would help?
[Android Head-Units] Jgn_:
Go to settings, system info. factory settings -> 8888 and check that you have selected the correct CAN
[Android Head-Units] highlandsun:
Here's my old and new MCU versions
[Android Head-Units] highlandsun:
Ah yeah, the MCU update appears to have reset my CAN device to 0x00... I changed it back and the button is selectable now, but it doesn't have an Online update. It wants a local file. I have no idea where to download this. Any ideas?
[Android Head-Units] Jgn_:
go to the CAN modification option in the factory settings. Some software versions for the A007 have the option to select the brand and car model. You may only have one to choose from but you may have a whole list. check this
[Android Head-Units] highlandsun:
I've got a long list of CANbus manufacturers and car models to choose from, but I've tried all of the Ford variants already. I think maybe I just need to connect the ILL wire from the Ford quadlock jack to the radio and forget about CANbus for this. The pin isn't present on this wiring harness but I've already got a pin kit ordered.
[Android Head-Units] highlandsun:
It seems the ILL wire on the Ford harness isn't used in these model years, so it has to be CANbus. Dang.
[Android Head-Units] Anton TNT:
Buy on Ali Express new one (but change model - like if now box is simple soft take Hiworld - it says what model and software is on the rear side of box - but first check in your system settings for canbus what models supports - SIMPLESOFT, HIWORLD, GENERAL, RAISE) or ask seller to give you new better canbus box. This one obviously doesn't work.
[Android Head-Units] highlandsun:
Yeah, good idea. This is the box I have right now, no idea what name.
[Android Head-Units] Anton TNT:
I don't know either strange, maybe it is "GENERAL". Use HIWORLD canbus it's the best, but must search correct one for your car. And similar software to use it on car settings (see available softwares on canbus settings - for your car model and year)
[Android Head-Units] highlandsun:
This looks like the right Hiworld box for my car, Mk 2 Focus (2009). https://www.aliexpress.com/item/1005004464351772.html

I also ordered this one yesterday before I saw your recommendation which looks to be RZC / Raise https://www.aliexpress.com/item/1005005218512049.html Will know in a few weeks when they arrive.

Has anyone found a better interface for the radio with station logos? The March update has logos but the radio hangs.
[Android Head-Units] bytechus:
If anyone knows how to edit and modify it, I would appreciate it.
[Android Head-Units] Anton TNT:
It must be used apk tool and android studio to unpack and develop radio app and then integrate it back as apk installation
[Android Head-Units] bytechus:
Thank you. But I am unable to do it
[Android Head-Units] highlandsun:
Actually, according to the factory service manual for this model year, the ILL wire is still provided. So adding the pin to the wiring harness may be the right approach after all. I noticed that some of the cable sets on Aliexpress appear to have this pin (from their photo) while most don't.
