Hello,

I tried searching for something similar but was unable to find anything.

I have a rooted Pixel 6 and would like to be able to archive (tar) and zip a directory via adb.

I have tried using the tar command via adb but it's not working as I expected.

I looked online and it seems that there is limited capabilities here for Android at least based on search results.

Are there any tools that can be installed for utilizing this via command line?

The bigger picture is I am trying to write a python script to automatically do this using pure-python-adb

Any tips are appreciated!

NFC Tag, one touch turn on Wifi hotspot for Head Unit in car.

After Android Oreo V.8 they cut off the command to open wifihotspot by NFC for some reason. I want to use this function to turn on wifihotspot to share internet for head unit in car.

Been trying for several days to find a script called Oreo Wifihotspot that he wrote that can send massage to turn on hotspot when we just touch NFC Tag.

when used for real It works as he said. But... when we touch Tag, there will be a diabog asking to run again. It wastes time having to press the screen again for the wifi hotspot to work.

I don't want to give up, just touch Tag once and the wifi hotspot works. I haven't been able to find it.. Until I came across an article of A foreigner talks about DIMPLE app. I went to search until I got apk to install in my device (can't load in play store) then try to write code to Tag NFC .....Bingo... .>>

Now I can tap Once and then the wifi hotspot works now.... This tool is useful. When we get on the car We take the mobile phone to touch the Heat unit 1 time, the mobile phone will release wifi to the car immediately, very easy.

i had successfully rooted my Galaxy A71 (Android v13) with Magisk, but then I uninstalled Magisk (Complete Uninstall), now I reinstalled Magisk v26.1 via APK and this is what I see:

View attachment 5903817

I lost root?

How can I go back to the previous situation? do i need to flash my device again with Odin?
[Android Q&A, Help & Troubleshooting] ethical_haquer:
The Magisk App (.apk) does not do the actual rooting, it is simply a GUI (graphical user interface) for the behind-the-scenes actual Magisk. According to your screenshot you only have the App part, so no root (see how it says "Installed N/A" under "Magisk"). In order to root your device do this:

NOTE: The below instructions have been copy/pasted from Magisk's official Installation Instructions

Before Installing Magisk

Installing Magisk WILL trip KNOX

Installing Magisk for the first time REQUIRES a full data wipe (this is NOT counting the data wipe when unlocking bootloader). Backup your data before continuing.

Download Odin (for Windows) or Heimdall (for Linux) that supports your device.

Unlocking Bootloader​

Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.

Allow bootloader unlocking in Developer options → OEM unlocking

Reboot to download mode: power off your device and press the download mode key combo for your device

Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.

Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.

Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.

Your bootloader now accepts unofficial images in download mode

Instructions​

Use either samfirm.js, Frija, or Samloader to download the latest firmware zip of your device directly from Samsung servers.

Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5

Press the Install button in the Magisk card

If your device does NOT have boot ramdisk, check the “Recovery Mode” option

Choose “Select and Patch a File” in method, and select the AP tar file

Start the installation, and copy the patched tar file to your PC using ADB:

adb pull /sdcard/Download/magisk_patched_[random_strings].tar

DO NOT USE MTP as it is known to corrupt large files.

Reboot to download mode. Open Odin on your PC, and flash magisk_patched.tar as AP, together with BL, CP, and CSC (NOT HOME_CSC because we want to wipe data) from the original firmware.

Your device should reboot automatically once Odin finished flashing. Agree to do a factory reset if asked.

If your device does NOT have boot ramdisk, reboot to recovery now to enable Magisk (reason stated in Magisk in Recovery).

Install the Magisk app you’ve already downloaded and launch the app. It should show a dialog asking for additional setup.

Let the app do its job and automatically reboot the device. Voila!

[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
Hello everyone,

I installed successfully LinegeOS 17.1 with this instuctions on my Samsung Galaxy A7 (2018). It works fine, but after installing system (it is rooted too) the charging is sooo slow (It takes more than one hour to charge only 7-8 %). I tried same cable (that charged perfectlly before installing LineageOS) and some others, but without success.

I tried with installing Magisk-modules too:

1) Notzeetaa - It is same

2) Magisk Fast Charge Version Green - When I try to flash, in the step when I need to choose option with volume up or down, it only shows numbers 1,23,.... and I cannot do anything. When I restart, it shows in Magisk, that FCGreen module is installed, but the charging is same

Can someone suggest, what should I do?
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
Why you installed LineageOS 17.1, It is like Android 10. If it was for the interface just install the Lineage launcher.
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
Reinstall the original firmware via sammobile.
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
And unroot.
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
But what if I want to use this system and dont want to root? Do you know how to solve problem with charging or not?
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
Flash the official ROM. It was almost unnecessary to move on LineageOS.
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
Yes, but then I will lost TWRP?
[Samsung Galaxy A7 (2018) Questions & Answers] cmfCyangenModteam:
Ofcourse, you will lost TWRP when you change ROMs, you will lost ROOT too.
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
Is there an option, that I install Android 10 and THEN TWRP (I want Android with TWRP)?
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
Yes, sure. Just install Android 10 and then, flas TWRP
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
But is there an option, that I install permanently TWRP?
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
What do you mean ?
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
I know I can flash TWRP after installing Android 10, but is it possible to have TWRP for always? I mean, will I have both: system and TWRP-recovery?
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
I think no, because when I flashed LineageOS in my Tab E Lite, I can't go to TWRP anymore.
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
What is this now??? I had blue and black colours when I boot (I could see logo, but barely). I could go into system (Lineage), but I see things only in blue and black colour. NOW I DONT SEE ANYTHING. Can someone explain why is this happening and what can I do?
[Samsung Galaxy A7 (2018) Questions & Answers] cmfCyangenModteam:
Failed flash.
[Samsung Galaxy A7 (2018) Questions & Answers] Samarimama:
Maybe you bricked your device, can you try again flashing the firmware ?
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
I dont understand. It worked perfectly, but now I see only black screen.
[Samsung Galaxy A7 (2018) Questions & Answers] dev_33:
I tried, but when I connect USB to my PC, PC detects it, but there is an error and I cannot see files from phone or do something with Odin.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Eon125:
Hey,

Whats currently the best available rom? I saw there is lineageos-14.1 but its kinda laggy on my Tablet.

There is SlimOS and few others and even a 8.1 if i read correctly. Basically I want most lag free as possible and good compatibility. If camera doesnt work, that doesnt matter.

Thank you for any recommendation.

Orion OS, Omni 6 and RR. Dont install gapps and it will run much faster
[Android Head-Units] texlaws:
So, I did some work and found Android 11 & Android 12 for the 8257 and both works, great. Along with the MCU update. The AC8257_Android_scatter.txt, found in both android files are known as project ac8257_demo, with platform MT6761. I have found that these android files are used by other head units such as Bosion ( true B200, I have it), Eunavi, VW Skoda Seat, and others that use ATCUPG update.

The kernel version of the 8257 head unit is 4.9 and is one of the most stable kernels out today, so it could go to android 13, if anyone finds it.

The only thing is to Root it, now. So, if anyone has a method, I could use it. Please try it first.

I also need to find a way to get to recovery mode.

Android Version: 10

Hardware Information: B200 - Core 8 - ROM 64GB - LPDDR4 - RAM 4GB - 1024x600

Kernel Version: 4.9.117+ #787 Wed Mar 23 14:24:04 CST 2022

OS Version: KC1G0101-PF3 - 2.1.2 - 20220323 – R06 - N4

MCU Version: STM32 - 202211229-11-BD2

CAN Version:

I started on Android 10, then Android 11, and now Android 12.

UPDATE!!!!!!!

Hello, just to let everone know I found an updated firmware version of Android 12, with update 2023.02.16 ATCUPG Android 12 and user themaang found a version 2023.08.08 ATCUPG Android 12, both are in my one drive for download.

Both need to be updated and they have updated features like the EQ has Bass gain for more Boom, but I'm looking for Android 13, "ATCUPG" file, along with how to get into recovery mode and Root.

As a reminder you must link to WIFI, update play store and update all APP's once loaded. the play store on the firmware is 19.3.26-all and the newer play store updated to "play store 35.2.19-21". you could try to update it to a higher one, but it is not needed, then update all app's through play store by searching for them individualy and update. This will link them to the play store account and update automaticly.

Second Update Android 13: B200 2024.03.11 ATCUPG Android 13 in google drive above

Found Android 13, loaded it and looking into API 33, looks good, on page 5

How did you update the unit? I have the same one and would like to update to android 12.

Does the wired android auto and apple carplay still work?
[Android Head-Units] texlaws:
Download the file : Extract/Unzip the  ATCUPG folder to the USB drive.

Your USB drive must be FAT32 only or it will not work / Not Take the update,

yes ***Fat32*** , Not NTFS!!!!!

Do not turn off the car radio during this operation and if needed start the car, brfore running update.

Turn on the car radio and plug the USB drive with ATCUPG on it.

Go to the “settings” menu and click on “ Upgrade and Reset/Update and Reset ” then on “local upgrade/local upgrade” find it and start the upgrade

A message could pop up indicating that the system will restart appears, click on “ok”

The update steps will appear on the WELCOME screen

once done, it will restart. Remove usb drive and Download file: mcu_202211111001BD2-1157.upd

step 2

Delete the “

ATCUPG

” folder and copy the file named “mcu_202211111001BD2-1157.upd”. Only the mcu file must be present on the FAT32 USB Drive.

Go back to “Settings”, then click on “Upgrade and Reset" and on “Upgrade Select “mcu” and click on “upgrade/update” The update is in progress, do not switch off the car radio.

Once done you should connect to wifi and set up your accounts, this will finish up the update needed.

Thanks,

TexLaws

I have a question. I have a Android car screen but my 360 app says I have to activate it. It says I can do this with a wechat mini app. But can not find how to do this.
[Android Head-Units] Rocket_rl:
Hi, I have the same unit but I dont have the 360 app? What is this used for? My guess would be to download the wechat app, make an account and scan the QR code from within the WeChat app
[Android Head-Units] vipinholland:
It's for the 360 camera. So I have 4 camera’s.

I have installed the wechat app and search for the mini app but it cant find it. Maybe it is in Chinese... But I can not write chinese
[Android Head-Units] Rocket_rl:
I'm afraid I can't help you then. Have you bought it from Amazon as well? From JoyX?
[Android Head-Units] vipinholland:
Yes from joyx
[Android Head-Units] Rocket_rl:
That sucks man. I see you live in the Netherlands as well. I am currently having the issue that Apple CarPlay isn't working anymore, while android auto is, and I have no clue how to fix it and the seller is pretty slow
[Android Head-Units] vipinholland:
Is it possible to flash an other firmware from a other manufacture?
[Android Head-Units] texlaws:
yes and no but know how to fix it before you start.

I need recovey mode to try some of the other firmware i have.

If anyone know how to get into recovery mode, I need the help. and I know nothing about the 360 camera sorry
[Android Head-Units] Rocket_rl:
Do any of you know how I can get SWC working? It has worked before but after I fiddled with some settings it doesn't work anymore. I'm really starting to get sick of this radio and things not working...
[Android Head-Units] vipinholland:
I don't want to brick my device so I think I will not try it 😔
[Android Head-Units] Rocket_rl:
I have no clue how to get into recovery mode... I think you would need to open up the radio and bridge the pin C17 pin (see pictures)
[Android Head-Units] Rocket_rl:
I have decided to return the radio I have because it just does not seem to keep working properly. Now the SWC is not working anymore, plus the Apple CarPlay does not work, and the seller doesn't seem to know how to fix this issue. So I am kind of done with it, and contacted Amazon to tell about these defects on multiple radio's the sell (this isn't the first radio of JOYX that I have tried).

So if you have a radio from JOYX and it works keep it. But if it doesn't, the chances are small that it will work again, and if possible you should return it.
[Android Head-Units] texlaws:
Sorry I could not help, but I do not have a JOYX brand. The system or USB could be loocked by not allowing updates or patches. You did the right thing early.
[Android Head-Units] Rocket_rl:
Noo my man, you did more than the support from the maker did. They might send a firmware update later, but I also ordered a new radio so I'm going to wait for the sellers response and then decide.

Again thank you for the instructions! :)

Hello,

Do you have any screenshots of android 12?
[Android Head-Units] texlaws:
Android 12 links through android auto or car play, mine is android auto and it links to phone once the truck is turned on, and it starts Spotify music. Here are the starting screen shots
[Android Head-Units] dj.shauny.g:
That seems like a fake version of android 12. I would flash android 11 as it is more stable
[Android Head-Units] taysco:
Hi there @texlaws !

I would love to get Android 12 on my device. I asked for it from the supplier and they hacked/faked it on Android 10 lol. I was like uhhh this ain't 12...

But seeing your post, I think I have a headunit that can support Android 12? It looks like I have the 8257 chip. Are you able to tell from my screenshot if my device is compatible with your Android 12 release? Also.. what does dude above me mean it's fake?
[Android Head-Units] dj.shauny.g:
By fake i mean it is based on android 11 and not android 12. Although it says Android 12….it is not.
[Android Head-Units] Miiick3y:
Perfect Android 12 image for me. Very fast Wireless Android Auto, with full 1024*600 resolution (which was not the case with an Android 11 image from another post, it was only 800*480 wireless and 1024*600 wired) Also I had a subwoofer problem with the Android 11 Image, almost no sub before 30/40 volume which was annoying, fixed with this image.

Thanks a lot !

You should be able to reboot to recovery via terminal emulator. Just type "reboot recovery". You may need a keyboard to navigate. I was able to reboot to recovery that way but I do not have a keyboard with me currently, so I couldn't navigate.

who ever made this rom,removed orientation option in factory settings.
[Android Head-Units] texlaws:
I had android 10, then updated to android 11, then to Android 12 and it is not a hacked out rom, for I have seen hacked roms in tablets and head units, but if you know of any others roms, that run for B200 Bosion, AC8257 or any 8257 head unit I would try, but I need to be able to get into recovery mode when the unit is turns on, not a emulator.

Recovery mode can fix bricked units and provide hope to all unit of silular problems but I cant find the short key to get there. once you find that if the unit is none responceive revocery mode can fix, just need to find out how to get there.

with respect to all post

Thanks

Mine is rooted
[Android Head-Units] scousemartin:
Mines rooted, with this version 12 that i flashed from here
[Android Head-Units] scousemartin:
To activate it you need to contact the author of the 360 app on the wechat app ,then you would send them that qcode and then , probably for a fee, they will activate the 360 app for you , so you can use it.

See if this video gives you any help, as its the only one i can find on the 360 app
[Android Head-Units] ahmad.alaa:
Thanks for this post.

i tried both and i got painful issues with both of the unfortunately

Android 12: very nice however my mic (INT and EXT) are not working at all with that rom, i tried may ways but seems to be not working

with Android 11: i can't run both radio/local music while having AA open and also can't have calls over Bluetooth from messenger /whatsapp etc.

[Android Head-Units] scousemartin:
Only problems i have with Android 12 , is that my touch buttons on screen, dont light up and i cant find a setting to turn them on, only a problem in the dark and another one which i will remember soon :)

I have just remembered the other problem i have with this rom, turning the beep off for when you have touched the screen. Anyone know how i can solve that?

Well i feel like a complete idiot, found both the settings eventually forgot the chinese use headlights for panel lighting and buzzer for touch :) Both enabled/disabled so everything is good for me. Thanks for thelinks to get this rom.
[Android Head-Units] scousemartin:
There are other ways to use apple car play than the default rom program. I dont use Crapple products though so cant recommend any i know working
[Android Head-Units] scousemartin:
I was going to go outside to try this out but have you tried pressing reset wh8ile holding the power button on? Cant remember which unit it was but i was sure that an old unit i had, i used to be able to get into recovery menu like that.
[Android Head-Units] scousemartin:
Does anyone know how to use navigation and music player, so they are both displayed side by side on screen, as i cant see any way of doing it with this android 12 rom? Even though the option is enabled in settings to allow it.
