[Google Pixel 4 Questions & Answers] V0latyle:
Never ever lock the bootloader unless everything is 100% bone stock. Not even a patched image. If anything is modified, locking the bootloader will prevent the device from booting Android, and it may not be possible to unlock it again. I'll have more for you on ROMs in the morning, specifically GSIs.
[Google Pixel 4 Questions & Answers] Sanman99:
Or I think I got that confused with the Settings menu OEM Unlock

Not the fastboot command.

I just did whatever the GrapheneOS instructions said.
[Google Pixel 4 Questions & Answers] V0latyle:
Well, GrapheneOS sets a custom root of trust, so as long as nothing is modified, you can relock the bootloader. You won't be able to have root, though. I generally advise against locking the bootloader unless you're on bone stock firmware.

As for ROMs, I don't have a lot of experience with custom ROMs, especially not in the past 6 years or so. My daily is a Pixel 5, and I'm pretty happy with the OEM firmware. I do have a Samsung tablet that I'm running an AOSP Developer Preview GSI on; I had tried LineageOS first, didn't like it that much, then figured out how to install a GSI. The Pixel 3 and newer should be Project Treble compliant, so you could potentially use a GSI if you wanted.

By the way, GSI = Generic System Image. The idea is that it can run on almost any device, utilizing the stock kernel, and does not require porting or any other customizations to get it to run on other devices.
[Acer Iconia A700 and A510] Darmach:
Hi everyone!

I just found an old tablet of my kid - Acer Iconia A510. i'd like to reuse it for something, but it seem I flashed some old cyanogen back then - Android 4.4.4 so pretty antique, and troublesome in 2023...

Can someone point me to what newest possible ROM I could use to bring the old guy back to work? Or it's too old to flash anything newish?

Sprint uses LTE Band 41, which your Xiaomi Pocophone F1 supports. However, you need to check if there are Sprint masts in your area that transmit on Band 41.

[FYT Android Head Units] cryptyk:
I went to developer settings and turned on USB Debugging.

Went to USB mode and turned on File Transfer

Tapped the 3 dots at the top right of developer settings and chose the second option.

Now I have the USB harness connected, which gives me a USB cable, but it's female so it doesn't plug directly into my computer. I used a USB-A to USB-C adapter on that cable, then used a USB-C to USB-C cable to connect to my laptop.

But I can't get adb devices to recognize it. I've tried every combination of the "three dots" menu and USB transfer mode, but nothing works.

How do you get USB debugging to work on this device? I've been using wifi, but USB would be much better for what I'm doing.
[FYT Android Head Units] cryptyk:
And maybe more importantly, how can I get fastboot to recognize my laptop?
[FYT Android Head Units] Gunde:
Should work. Try a new cable without the adaptor.
[FYT Android Head Units] cryptyk:
But the cable that comes from the headunit is usb-a female. How can I plug that into my laptop without an adapter?
[FYT Android Head Units] Gunde:
You'd have to get a new cable that plugs in directly. It's the only thing I can think of. I got it to work on mine, with the second option on the 3-dit menu ...
[OnePlus Nord CE 2] John Scrambler:
Soooo, flashed boot, forgot to flash vbmeta b4 rebooting. Rebooted, got device is stuck on a bootloop.

Now fixes to stop the bootloop require going into fastboot mode, but how can I stop the loop, and start the fastboot mode?

Thanks in advance!
[OnePlus Nord CE 2] John Scrambler:
Somewhat fixed, gonna leave here how for the future. When stuck on a bootloop, from the moment the OnePlus/Android logos appear on screen, press "Volume Up" and "Power Buttons".

IMPORTANT: when the screen turns off, release the keys, or the phone will reboot and not break the loop.
[OnePlus Nord CE 2] John Scrambler:
So now., can turn off the phone. Have been trying to get to Recovery mode with no success.

Have tried starting the turned off phone by pressing:

Power + Volume Up -> powers on or off the phone

Power + Volume Down -> nothing

Power + Volume Down + Volume Up -> nothing

So now, just need a way into recovery/fastboot. I must be doing something wrong, maybe pressing the buttons for too long or smth like that. Has anyone unbricked an phone like this before?

Also, something wierd is happening, the phone auto boots when I connect it through USB.
[OnePlus Nord CE 2] ko_hi:
if you're on android 12 theres no way you can recover from it without going to the Service center. if you're on android 11 volume down + power should go into bootloop.

the main problem in Android 12 is that fastboot is broken. and it will boot into fastboot for a milisecond or two then reboot out of it
[OnePlus Nord CE 2] John Scrambler:
Hey! Thanks for the help ko_hi! Sadly It is on Android 12, so I guess I'll go to the Service center!
[OnePlus Nord CE 2] ko_hi:
if you decide to try root A12 again i can see if i can help you getting it "safe"

[OnePlus Nord CE 2] ko_hi:
You need to flash back stock boot
[OnePlus Nord CE 2] Keycard755:
i guess i download wrong boot now im stuck here

in orange state

telling your device is unlocked cant be trusted your device will boot in 5 seconds

serial number not matched

fastboot unlock verify fail and keeps rebooting
[OnePlus Nord CE 2] ko_hi:
If you're on A.09 just use exploit to flash full rom
[OnePlus Nord CE 2] maverickluke:
Hi ko_hi,

I have my Nord2 5G as the first with the original “update” back to the last A11.

Then I pulled the boot image via TWRP (adb shell -> dd if=... of=...), patched it with Magisk and flashed it again (with VBMeta).

Until now everything was ok, but suddenly I had no more root access and a reboot ended in a bootloop

With A11 I still have fastboot and there I reflashed the boot image previously saved via TWRP (with dd). But I am still in a bootloop.

Do you have any other ideas?

edit: i hope this can be fixed without wipe.
[OnePlus Nord CE 2] ko_hi:
Nope it can't be fixed and since it kills adb it's hard to say why it happens

[Android Head-Units] smsm_elnabawy:
Hello everyone,

I have the following chinese head unit. When I switch the ignition off, it only closes the screen but the head unit itself keeps operating.

It keeps paired with my bluetooth and hotspot. Doesn't shutdown.

I tried to install an application for shutdown and when I use it is shuts the unit down and then reboot it..

I tried to enter the factory settings and switch it to direct shutdown but no use. I also tried to enter from the factory settings (Engineering debugging menu) and switch it to user settings but still no use.

Can anyone help how to shutdown this head unit?? It keeps draining my battery as it when I tried to measure the parasite load when it is running but screen shutdown and it was 0.6 Amps. which is a lot...

My last resort is to make an external power switch to it.. which I really don't like but what can I do...

Waiting for your feedback as you might help me with it!

Thanks in advance.
[Android Head-Units] theking095:
Mine has a connector for demo mode that I had to unplug so the head unit will turn off when the switch is off
[Android Head-Units] smsm_elnabawy:
So you have to physically pull out a connector for it to power off...

But in this case it won't shut down... you will just cut the power off it. Isn't that harmful to the unit hardware and software?
[Android Head-Units] Anton TNT:
There are two reasons why unit is not to shuting down...

First - in "settings" or "infotainment" area find UNIT TIMEOUT / SHUTDOWN SETTING , must be at value "0 min" instead of max min.

Second - Red wire (ACC+ KEY) from cable harness is connected to 12V battery constant (usually it is yellow wire), switch those and see if helps. Key for ignition must turn unit off when shuts down engine.
[Android Head-Units] smsm_elnabawy:
I already connected the Acc wire to the Acc, that's why when I switch the engine off and remove my key the unit only closes the screen but it doesn't shutdown.

For the Unit timeout option, or shutdown option, I can't find it on my unit OS... tried the search function and tried going through each and every bailable list and choice but didn't find it!!!!!!!!!
[Android Head-Units] m00n61:
Connect both ACC and +12V wires from HU to car ACC. This way, when ignition is off HU power is off.
[Android Head-Units] TorstenH:
Don't think that's a good idea. Because this will interrupt power supply completely when you turn off ignition. This way the head unit has no chance to shutdown or switch into sleep mode. It's like removing the battery from your laptop.
[Android Head-Units] TorstenH:
I don't know your head unit but there may be an ACC delay option.

Some head units allows to set up a waiting time up to 60 minutes before shutdown/sleep.
[Android Head-Units] smsm_elnabawy:
Exactly, that's my point of view.
[Android Head-Units] smsm_elnabawy:
I can't find it t all in my options!
[Android Head-Units] Anton TNT:
There is an option for that just need to find it, if not in settings or in infotainment area try in factory settings
[Android Head-Units] smsm_elnabawy:
Okay as an update for the situation,

I couldn't find an option for it, however, I installed an APK file for shutdown and restart.

In addition I rewired it so that the main +12V wire to an (on/off) switch, when I want to shut it down, I just use the APK I installed, wait until it shuts down, when it tries to restart again I use the On/Off switch to permanently power it off....
[Android Head-Units] Anton TNT:
Ok , but there is no need for application, on factory settings when you type in PIN codes just enter PIN 1414 and device will shut down, that is code for my device.
[Android Head-Units] smsm_elnabawy:
Really?? didn't know that.. I will try it and let you know the result.

Thanks a lot :D
[Android Head-Units] kabelgleichung:
Did you find a solution for this issue? My head unit stays in sleep mode forever and does not turn off, although I have set the sleep delay in factory settings correctly.
[Android Head-Units] marchnz:
What is wrong with sleep? Answer: Nothing!
[Android Head-Units] TorstenH:
Sleep delay? Are you talking about ACC delay?

Nothing is forever but how long is your forever? Usually the head units stay in sleep mode for around three days before shutdown.
[Android Head-Units] kabelgleichung:
Yes ACC delay. The delay is configurable. I have set it to 10 - there is no unit, but the unit does not turn off after 10 (seconds|minutes|hours). As maximum is 3600, I presume the unit is not days.
[Android Head-Units] TorstenH:
ACC delay means: how long to wait before entering sleep mode after ignition is off. This has nothing to do with the sleep duration. I don't know any head unit which allows to configure sleep duration.

[ign off] --> [ACC delay] --> [start to sleep]
[Android Head-Units] MrDSM:
So, you said that the sleep mode can not affect the battery, and causing a battery drain ?
[General Questions and Answers] lagrabow:
Could not find a forum for OTT boxes.

Please direct me to it, if it exists.

I was given an M8S OTT box and am trying to get it to work.

I have plugged it in to my TV [HDMI cable].

I have connected it to the internet via cat cable.

When I turn my TV on all I get is a M8S logo that states amlogic, H.265, 8 core, Mali 450 and Quad Core A9.

I have downloded the users guide but it is not a lot of help in the info department.

There is a USB dongle in a USB slot at the back for a bluetooth keyboard, the keyboard lights up, but again no reaction from OTT box.

The box that the keyboard came in says it is for an Android TV Box.

The remote flashes red when I hit buttons but does not seem to react.

The remote does not seem to turn machine on/off.

I have found a site that shows how to reset to factory defaults.

I have read about getting into recovery mode using a USB keyboard.

I have not done either.

Can anyone suggests what my next moves should be?

Thanks

First and foremost, thank you to everyone who has helped in this matter. I do understand that this is an older piece of equipment and my knowledge of it is on the low end. I was hoping that being a Linux derivative there was some hope for it, as I don't like waste. There are few markings on it, which doesn't help. As well as my inexpertise about these devices.

So, now, I am looking for a "brand" name tv box (other than chromecast, roku, fire, etc.) that I can look into. Not really interested in used. Android(configurable) preferred. I live in CANADA if that makes a difference. My use for the tv box is mostly news and documentary with a little entertainment thrown in. Netflix, et all, I am not interested in, although I like movies. I have cut the wire so to speak and do not subscribe to any of the big TV/Internet providers.

I do not recognize any names of the Android TV boxes I have seen in any internet searching, so, if someone could provide some names that are good equipment in this line, I could check them out and get on with this.

Thanks.

Edit2: are you sure that Fastbootd (or regular old fastboot) is not working like on the A52s? Try enabeling adb in Developer Options and issue the command 'adb reboot fastboot' and if that doesn't work try 'adb reboot recovery' to see if that one does work.

Oh, after looking through the git repo mentioned in that post I think I am starting to connect the dots. You currently have the sammy default recovery patched and installed, and now you want to modify and 'build' twrp to include the fastbootd daemon for this device? Cuz that is completely unnecessary, fastbootd has been implemented into twrp since oct 21 2020 (according to the git enviroment of the developers).

All you would need to do to enable fastbootd is reboot to the bootloader/fastboot from within twrp (at least I think, I cannot test this currently as my daily driver (A52s) is still vanilla OneUI with untripped knox fuse, and will stay like this untill it's out of warranty and I don't have any of my old devices with twrp installed on me 🤣)
