Cannot reboot into recovery mode - tried lots of stuff - Android Q&A, Help & Troubleshooting

So I want to make a clean hard reset of my GoClever Tab R974.2 but no matter what I do it won't load the bootloader. I tried all pssible combinations of all 3 abailable buttons (power,vol+,vol-) and all possible pressing times from a few seconds to a minute.
I also tried rebooting into bootloader via the ADB but without any luck (device not recognized).
My main problem with this system is that I tried to root it and it seemed like it worked, the superuser.apk was installed, however when I tried to start Titanium backup or any other prog that requires root access, it shows that there is no root access. Then I also tried z4root, but no luck either and SuperOneClick just freezes when restaring the ADB daemon.
The tablet still works nicely but I need to root it so bad
I am at the end of my powers, please help anyone?
Here are the tab specs, maybe there's a similar tab?

I have tried Gingerbreak (left it for over 30min in rooting screen) and SuperOneClick (remains in waiting for device, have tried troubleshooting such as turning on and off Debugging Mode".
I have scoured over "unofficial CyanogenMod7 port for RK2818 tablets" however it says that this will likely brick you device if it is not listed, which this device is not. I hope I don't sound like a noob here, and any help will be appreciated.

Anyone there? haha
try this
try with the attached superoneclick in case you can't find one from the net.
Use super manager app for root access.
Cheers.
Good luck
To root your aocos n19, you need:
-VTC Driver v4.01 for 2000 XP.exe (to install driver of your device);
-and SuperOneClick (personaly, I did it with superoneclick v2.3.3);
-your aocos n19, a PC with windows 2000 or XP and a USB cable.
First, run "VTC Driver v4.01 for2000 XP.exe" to install the driver.
Then plug your aocos n19.
Finally run superoneclick and press "root" button.
Your aocos n19 is now rooted, and if you want you can unroot it with superoneclick.

Hardware Initialization sequence change - HELP

Hello guys and gals
I am not a developer and my knowledge is not that perfect but from my experiment with different x 86 Roms I have come to conclusion that when a rom starts up there is a hardware initiation that happens with in the rom instructing what hardware with what drivers should load first.
Here is the thing, I do not know how to edit the sequence of this as I have a laptop that in which the built in wifi gets initiated first then followed by the USB ports on the system.
When this happens since my laptop is the latest model running on Intel 6 Gen hardware, the built in wifi card is not supported by android M which causes me not to have a working wifi.
I have a compatible wifi usb dongle that is 100% compatible but since the system initiates the internal wifi card first, android locks into the first card initiated and ignores the wifi dongle plugged into the USB ports.
Now I need help to find out what file needs to be change in order to change the hardware Initialization order and let the Rom load up the USB ports first, and then later on search for the built in wi-fi card in order to fix this issue I have
Laptop spec and model:
XPS-9550
I7 6 Gen, 32GB Ram, Samsung 512GB Nvme SSD, 4K touch display
Do let me know

You should be able to blacklist the module for the internal wifi; via grub or a file in /system/etc

Tablet has never been modified in any way.
What I've tried:
Tried to boot to recovery/bootloader to reset tablet.
Key combi power + volume up does absolutely nothing, just boots normally.
Key combi power + volume down goes to a recovery screen but it has the android with the red exclamation mark & no amount of key presses does anything.
Key combi power + both volume keys does nothing.
When tablet is at lock screen, I can connect to my pc & see the tablets sd storage.
Placed a stock rom in the sd storage & the device detected it, rebooted, installed & then restarted with no problems.
Sadly the password was still in place.
Ran android sdk tools.
When tablet is at lock screen, adb/fastboot command adb devices will not detect it even though I can access the sd storage.
When the tablet is at the recovery screen with the exclamation mark android (described above), if I enter "adb devices" adb comes back with "G82XOIPUY0 recovery"
If I issue command adb reboot recovery, it reboots back to same recovery screen whereas command adb reboot bootloader goes to a black screen & I can't tell if the tablet is on or off.
In windows device manager, when the tablet is in the recovery screen, it show as an Asus Android Device & the driver sub menu is Alcatel.
When at the lock screen, Asus Device disappears from windows device manager & NEXT7D12F appears under Portable Devices.
Thanks in advance for any & all advice.
Cheers

Archos 50 Diamond - how (is possible) to custom recovery or ROM without touch screen

Hello, i have Archos 50 Diamond with stock Android 4.4.4 Kitkat:
gsmarena.com/archos_50_diamond-7042.php
archos.com/us/products/smartphones/diamond/archos_50diamond/index.html
postimg.cc/gallery/ctjgb6yk/ (images of Archos 50 Diamond internal parts and removed LCD glass, digitizer and battery)
Issue: Phone is restored to factory default, screen displays good, but is cracked in the corner and touch does not react.
My aim is to run Android app on it and be connected to the internet via WIFI or run general Linux app like SSH, rsync on any ROM that would work on the device.
So i need to somehow control the device via either USB (manufacturer says MicroUSB V2.0 support), bluetooth or via wifi (i read some apps can manage phone via wifi thanks to higher android version (maybe lolipop and up).
1.
I want to ask if i can connect USB hub with the mouse and keyboard or if there is hardware limitation. I tried to connect the mouse, but it not shown any cursor in post installation menu after boot (where one select language).
If there is a SW limitation, i found there is Android 5 Lolipop beta (blog.archos.com/en/beta-version-of-android-lollipop-for-the-archos-50-diamond/), but i am unsure if i can use that update.zip on sd card and update from sd card in stock recovery menu. (from the article they speak about internal storage)
2.
Next question is if i can use some "update from SD card" package that would enable ADB and USB debug mode or
3.
if there is any ROM for this phone that would support connecting USB peripherals and WIFI. I found no ROM for this exact Archos phone.
4.
is there any custom recovery for this phone? i also not found any that would indicate this phone type
5.
is there any package for rooting the phone via stock recovery "update from SDcard" function?
6.
the repair of the touch function is doable by me or for low price under $50 ?
Thank You

Bell is shipping me one of their streamer devices and looking at the specs, its just a repackaged ADT-3 device with a custom Bell ROM on it.
Since all my TVs already have capable devices attached to them, this frees up the streamer for exploration and fun. I was wondering if anybody has managed to unlock the bootloader and load custom roms to this device?

Hello
They send me one for free and i tried installing ADT-3 Stock ROM after reading Bell Terms of service and ended up bricking it
I tried using Amlogic tools to unbrick it but i unfortunately the board is Password protected since the Frederic exploit.
I have currently wiped all partitions to make the processor (Amlogic S905Y2) look for SD and USB Boot devices. which it is now doing.
Serial output:
G12A:BL:0253b8:61aa2d;FEAT:F2F939B2:32060;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8;

I'm currently searching docs / forums to read to get a better grasp on the required images and bins to make a Bootable USB for this device.
If you are wondering how i'am getting USB Drive on that device i'am just using a OTG Converter and using an modified HUB To inject current in the device, you can basically achieve the same by cutting the USB Lead and injecting voltage.
I will keep this thread up to date if manage to unbrick it a flash custom ROM on the device.

The ADT-3 uses an unencrypted bootloader. The Bell Streamer doesn't. The device is looking for the encrypted Bell Streamer bootloader, but in this bootrom mode it will only look on the emmc or a sd card. As far as I know, at this stage, it can't boot directly from USB. If you discover otherwise, please let us all know.
The reference to USB that you see in the above string is for a bootrom worldcup usb connection. As you noted, this mode can't be used for much if it is password protected.
