[Android Head-Units] Allan_Hun:
Rear speakers playing as loud as front speakers will destroy your stereo stage.

So if you are serious about sound guality you want your rear speaker at low volume.

13.5V should not cause any problems. But I would definitely not power any amp from the head unit. Car amps normally have a "remote" signal input that doesn't really pull any power but tells the amp to turn on. Car amps draws a lot of current through a heavy gauge wire directly from the battery.

So I am pretty sure the "amp wire" from your head unit is designed as a remote signal telling the amp to turn on.

Bad things are likely to happen if you draw any significant power through the tiny amp remote wire so I would check how the amp was powered with the OEM headunit and use the OEM power wire. Alternatively you could run a new heavy gauge wire directly from battery to your amps power input.

You could install a simple NO relay to solve the low antenna voltage with engine of problem.
[Android Head-Units] Scooterran:
Thank you for your answer.

With the original cd-player front and rear speaker had the same volume. So I guess the audio system was designed to work this way.

However, new HU has a different design which was clear from the start since I had troubles event starting it up and now I must find some way to overcome it.

I was hoping to find someone else that had similar issues.

The low antenna voltage while engine is OFF is not a problem for me. Mostly I listen to music and rarely radio and since the car is ON doesn't really matter. :)
[Sprint Samsung Galaxy S III] Fafy:
Tried to test different custom firmware to stop at one of them later.

And I didn't replace it after that almost all firmware on androd 6 and 7 stopped launching.

All problematic firmware installs, but after a long wait for the first startup it produces a black screen error: "Process system isn't responding" and the "Close app" button. "Wait." which are not responded to by the system.

There are firmware versions that do not output errors, but after startup a black screen is displayed, and the firmware that is bootable and displays the desktop, do not respond to touching the screen.

Stock firmware and its modifications work fine, as does CyanogenMod on the fourth android.

What could have happened that these firmwares stopped running?

I need an android version 7 system.

I ask connoisseurs do not pass by, tell me how this case can be fixed?

Hello,

I'm trying to bootloader unlock this phone and have encountered the above error. I am using the OEM cable, and basic ADB commands work (adb reboot ______, etc.) The command fastboot oem device-info yields the same error message. I'm thinking I don't have the right USB drivers but the phone is so new I can't find anything for it.

Do you guys have any ideas?

https://xdaforums.com/t/rom-10-hadesrom-q-stock-v2-0-for-exynos-s10e-s10-s10-12-04-2020.4058441/)
[Xiaomi Mi 11 Ultra] Filip.Z:
Hi,

I wanted to know if this is normal on Xiaomi mi 11 Ultra, but

when I shoot in 4k 60 fps in HDR10+ (10 bit colors), I'm getting weird artifacts in the video. Look at: StockCamera10Bit.jpg

It's such an unusable mess. I'm shooting at PRO. It doesn't matter what ISO, shutter speed and white balance is selected. It's always this. Subject has to be moving.

If I select 8bit, it's ok, just normal motion blur.

Is it normal on this phone? Can anybody confirm it?

I have the same problem in McPro24FPS in anything over 30 FPS even in 8 bits, so that's troubling me a bit.

I have the phone for a few weeks now and it's just amazing how the video footage degrades, when you do not want to film in AUTO :)

And even, if you satisfy with AUTO and only lock exposure and focus, it's also crap, when you move the camera or something is moving in front of it :)

I can see, that the only thing that manufacturers are interested in is AUTO mode which gives you nice HDR, but is always changing exposure, so it's interesting only for YouTube reviewers and DXOMark I guess. But for semi-serious video shooter I'm still amazed how they market 8k video and I cannot get even decent 4k 60 fps for slow mo :( (not even usable Full HD in 60 FPS).

I would satisfy with 8 bit, but it's unusable in stock app, because it's changing exposure even if it's locked and other app give me these artifacts anyway...
[Xiaomi Mi 11 Ultra] GuyWithRootedPhone:
wait... did they convert 8-bit to 10-bit using bad dithering?
[Xiaomi Mi 11 Ultra] Filip.Z:
Alexander from McPro24FPS said, that it is a bug in HDR merging. It should have phones with HDR on by default.

It is some setting, that can be be turned off programmatically, but it's the matter of finding it.

Same issue unfortunately. The recovery doesn't boot. I've tried the lineage-18.1-20210725-recovery-lemonade.img version as well and still doesn't boot and I'm not willing to do fastboot flash to try that.

Hopefully someone can figure this out soon.
[OnePlus 9] toyanucci:
OK. So I figured it out.

You have to do fastboot flash boot recovery.img

Reboot to recovery then select the following on the phone:

Apply Update

Apply from ADB

then on the computer do:

adb sideload ROM.zip

Format data in the recovery then Reboot to system and it will boot up!

Did it just now and it works!
[OnePlus 9] mattie_49:
I figured just booting the recovery wouldn't work. Have to flash it. And it's fastboot flash recovery recovery.img

Then do adb sideload through recovery!!

I figured it out and got the recovery to boot. So i did the copy-partitions and now im sideloading the rom. Ooooh! Im excited :)
[OnePlus 9] AnierinB:
You're running the wrong command. You want to flash the recovery img to boot, not recovery.

Also, by the looks of it, you're not explicitly calling the fastboot binary in that folder.

While opened up in a PowerShell window in that directory, explicitly define that you want to use that fastboot binary by putting ./ before fastboot.

So

./fastboot flash boot ./recovery.img

./fastboot reboot recovery
[OnePlus 9] illusiveairforce:
okay i actually got the recovery flashed now. I installed the update. did all the steps and its just at the boot animation again.

Question. I also sideloaded Omega Kernal and Magisk. Could that be why its not fully booting? Its still at the E right now.

I just tried the commands you suggested ./fastboot and actually copied your commands and it says unrecognized at internal or external command
[OnePlus 9] AnierinB:
Afaik omega kernel only supports op9pro, not base op9. And on top of that, it's only for OOS.

Not sure why you're flashing custom kernels during the initial installation process anyways.
