Allwinner T8, no way to enable developer options - Android Head-Units

Hi guys! Reaching out to see if someone encountered this or have any suggestion on what I can try.
So I have this head unit for a while and I don't have major complains.

}
The only being that it has a version of Torque installed as a system app and I can't update it via Play store, as is says the signnature doesnn't match, and I can't sideload it either for the same reason. So I was hoping to be able to uninstall it via adb and that's where I problems started.
For me to use adb, I need to connect it via usb. problem is when I connect it via cable the pc doesn't see it, probably because the unit doesn't report itself as a phone. So I figured I could try adb via wireless. But either way I need to have usb debugging on. Which is a simple matter of enabling dev options right?
Problem is, when I go to Settings >> About Devices, I don't have a "build number" to enable dev options.
With this info, have anyone encountered a unit blocking dev options like this? I checked for videos of other Allwinner models, even some with the same specs, and it seems my unit has something different that doesn't have that option.
Any other way to get dev options? Or maybe a way to root it?
Thank you!

Did you try on clicking Android version several times? That will show a symbol (in my case, an oreo cookie) that will let you know that is has been granted developer mode.

I have dealt with a couple of these. Both of them had ADB already enabled from the factory via "Wireless debugging." I found this out after NMap'ing them and saw port tcp/5555 open on each. The SU binary was already on them too, all you need to do is open a terminal emulator on them and type "su" & hit enter. I suggest installing F-Droid on it if you can get to a web browser and get some apps from there like Termux. Curious if this one has the same thing (Cryptocurrency miner worm. Lookup "ADB Miner.") Here is a simple port scanning app you can check the device on your lan,...

[Q] Help! Screen broke with PIN lock, need help mounting file system with CWM.

So I had the magical luck of having my S4 fall out of my pocket while closing my car door, shattered to pieces, no touch response from the glass.
The problem is, I had the device locked with a pattern & pin, so I can't just plug in and backup all my photos and stuff that were saved with local device storage. I also can't get adb to connect to the device (with developer options enabled), I always get a "device offline" error (I've updated ADB to the current 4.2.2 version, but I cant whitelist it because I can't allow it from the phone without touch)
Now, I still have root, and I was able to blindly install CWM (the OUDHS-Recovery-jfltespr-1.0.3.3.tar) version with Odin. I'm assuming it went well because I heard the sprint chime on restart.
WHAT I NEED: Is someone to either give me some screenshots (or number of button presses) to enable internal storage to be accessible by usb in cwm (also how to get into it too). I figure if I'm able to use volume presses and the home button I can get to my internal files. Other than this option I'm at a loss before I return it. If anyone can help I would be so damn grateful.
I'll draw you a picture too.
EDIT 1: I have a picture of the main CWM screen from a youtube video here:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now all i need is the mount and storage menu
So nobody can help? I didn't think a cwm menu was that hard to come by with an S4.

Were you able to connect with adb before? Was usb debugging checked in settings before the drop?
If you could get adb to connect, you could use a program like android screencast to view your phones screen on your computer.

That was my first move actually.
Problem is, even though debugging was enabled, I can't whitelist my PC from my phone. This is a new 4.2.2 feature to prevent data theft ironically.
All of these options will just return an "adb: device offline" error when it's connected. Trust me, I wish it was that easy.
You can't connect while in recovery either?
It would be kind of a pain, but you could pull multiple files that way.

Unable To Unlock Bootloader

Hi,
Have been an owner of an M9+ for a few months now and it's taken me this long to not manage to unlock the bootloader so have caved in and decided to ask nicely for some help / advice.
Firstly, I live in the UK. I bought the handset from Fonis who are located in Dubai (best price, unlocked to any network, etc, etc) so am assuming this handset has got nothing to do with Verizon?
Problems..... the check box for 'allow OEM unlock' is not there. Doesn't exist. There is nothing in Developer Options to do with OEM.
When I boot the phone into Download Mode my pc does not detect it so am unable to proceed in getting the identifier token thingymabob.
Things I have done.... enabled dev options, enabled usb debugging, downloaded all the adb / fastboot stuff, shouted a lot and referred to the handset as a s teaming pile of s**t.
So, am I being extremely thick here and missing something obvious? Have I bought a complete donkey of a handset? (Fonis have good reviews online and that along with the price was a deciding factor in using them).
If anyone can help, great. If any further intel is needed then ask and I shall provide.
Cheers,
Rick
Do you have HTC sync latest installed? That contains the USB driver for the phone for fastboot to work
Yep, latest version of sync is installed. When I open HTC Sync with the phone connected to the PC while in download mode Sync states 'no phone connected'.
Have tried different usb leads and different usb ports but nothing is happening.

If you didn't try, maybe try connecting device, remove/uninstall driver of phone device instance in Device manager, reconnect and see if it installs correct driver. Sometimes wrong driver sticks with the phone device, if it was connected before HTC sync installed.
In developer options (in settings) you have to enable the bootloader unlock.

Help with this alps 825X_Pro device

OK, I just received this device:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
which is sold under various names from vendors @AliExpress.
I'm trying to match this unit with one of the threads here and it seems like no one is dealing with it, but I may have missed some relevant posts, can you please help me with that? Or maybe you know about other forums where they discuss the unit...
The device has several issues (bottom line: do not buy it, the hardware is okish but the software is horrible) and I'd really like to explore ways to customize it but I'm not even able to connect to it via adb, let alone become root or install a custom firmware...
Seem like no one heard of it. Bad luck.
I'm trying to gain root access and fix some of the bull***, but I'm running short of options.
What I know so far:
Invoking "su" from the command line (or via adb) returns a "not allowed" message;
I have no firmware to patch with magisk;
the amazing temp root does not work, the device is patched.
What else could I try?
I may try the MTK Droid Tools, but I think they use the same exploit used by the amazing temp root so I guess this is not a solution. Moreover they need Windows and I can't connect to the unit with adb in windows, only with Linux (heavens know why, the Universal ADB Drivers says it's all "ok" but adb does not see the device).
Did you get anywhere with it? I just got 825x_pro for my R56 Mini.
Nowhere. There seem to be some info in the 4pda.ru forum (in russian) but I did not dig deep into into.

Hi,
You have to go to:
- The settings
- "Car infotaiment" and click in the high right corner on the "cogwheel" and you get a little window where you have to type the numbers (example: 5678; 8888, ....etc ) And you get the hidden menu !

Yup this was my experience of "Fake Device Software" Could it mean it is fake? I downloaded another and found the device advertising it's self as Android 10 but with an API level of 28 which relates to Android 9 or wear devices so ???

[SOLVED] Unlock BTV-DL09, problem modem

Hello everybody.
I wanted to unlock an BTV-DL09 [ Android 7 EMUI 5.04 EU ], but I'm stuck like the_wing was.
Modem no found !
Phew, got it unlocked! Moments of terror when entering the commands on the cmd...
A few mentions where I got stuck that may help someone else:
Regarding point 3:
In case your model has LTE (i.e. BTV-DL09), you actually should have a dialer application that you have to use instead of the calculator app, which didn't work for me. This is also mentioned in the DC unlocker app. In case you do it with the dialer, you have to enter following code: *#*#2846579#*#*
Regarding point 4:
Inside the "DC unlocker" app, I also got the "device not found" error, and I was wondering why. Two things I noticed:
- To enable USB debugging, it was not sufficient for me to activate the switch in the developer options, as the default USB mode for me is "charging only". I had to change it to i.e. "Device File Manager (MTP)" by tapping on the notification and then re-activate USB debugging in the developer options (which turned off after switching to MTP mode) to get USB debugging working.
- After enabling "manufacturer mode", the mode was turned off as soon as I quit the menu. So I had to stay in the menu to make sure manufacturer mode is on.
- You can check your device manager in Windows to see if the current mode is active: When doing USB debugging, the device "Android Composite ADB Interface" should show up under "Android Phone" list, whereas when you turn on manufacturer mode, some COM ports should show up under "Ports (COM and LPT)"; the one DC unlocker is searching should be named "Android Adapter PCUI". If you got some devices with not properly installed drivers you should consider installing HiSuite software on Windows first.
Regarding point 8
- When I bought the credits for DC unlocker for PayPal, I had to click on a link arrived to the PayPal e-mail for confirming your account. I then still got the "Server login error", but closing and reopening DC unlocker eventually fixed it.
Hope this helps! Happy unlocking to everybody!

I have installed Hisuite and Huawei data card driver.
Impossible to activate Device File Manager (MTP) and manufacturer mode, one deactivates the other, I do not know if this is the problem, but according to the tutorials it is a must.
I have a hard time understanding where the problem comes from, I even tested different USB cable, Win 7 and Win 10, I really did everything, but I'm dried.

I finally managed to unlock the bootloader, DC unlocker did not show me information from the tablet, but despite this, I could go to the next step and proceed with the unlocking, it is because of a msie security update according to Valdemaras on cd-unlocker forum, thanks to him.

[GUIDE][Tool][WindowsOnly][NonRoot] USB Reverse Tethering

Hello there!
Since the most recent guide thread ((that I found) [GUIDE] USB Reverse Tethering - New method) does is quite
complicated for many and requires root and for the sake of simplicity, I wanted to present a simpler alternative
to you here in a separate thread, which works without root and is not outdated.
If this violates any XDA rules, please close the thread.
-This method works 100% on Android 9. For other versions you need to check.
-Very useful for people whose wifi module is broken (like mine x.x)
I will attach the .zip here as well as pictures for a better understanding.
Requirements are:
-A working USB connection
-USB debugging enabled.
-A Windows computer
-adb
First, of course, we need to unzip the .zip.
In this case it doesn't matter where.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Second, we need to open the console and go to the path of the extracted .zip
CD path\to\gnirhtet-rust-win64
Third, we press tab 2 times in the cmd, space, write install and press enter.
When that's finished, we press tab again twice, space and write run and press enter.
Alternatively, if "gnirehtet" is already installed, you can use the .bat, provided in the .zip to start it.
That's it! You got reverse usb tethering!
thank you for sharing, i followed the steps but didn't succeed in getting internet
i think you should mention having adb in systempath or just extract your program in adb directory
my steps were
get adb fastboot and extract it
get your program extracted inside adb directory
start cmd normally without admin rights
execute first command in your post to install ( returned success)
execute second command ( returnt 1 at the end ) but no internet
Code:
2022-07-30 00:41:44.389 ERROR Main: Cannot start client: Command adb ["reverse",
"localabstract:gnirehtet", "tcp:31416"] returned with value 1
i should am running AOSP 7.1
**solved
i report it working on AOSP 7.1
solution = use an up-dated version of adb-tools

I think that's a problem of the application, which wants a specific connection e.g. wifi or mobile data.

This should be no problem.
It was creating the problem but then I just reflashed whole stock ROM and bam my phone is better than before
working thank you for this program.
You may also check the re-link app at https://re-link.io, as it doesn't even need ADB on Windows, making it safer to use
