[Q] REEDER W7iC TABLET=EMDOOR EM-I8170 WINDOWS 8.1 TABLET WON'T TURN ON

Hi,
Sorry, for my poor English. I'm from Turkey. I bought a Reeder W7iC windows Tablet in Turkey. It's the same EMDOOR EM-I8170. I installed the wrong bios file, while android trying to install. Now, tablet won't turn on. Back light is on. I connected keyboard and mouse on usb otg. It all works. l I found the original bios file. How do i run again it? How do i install android? Thank you in advance for your help.
Tablet specifications:
Intel Baytrail-CR Z3735G, Quad Core
1GB DDR3 FLASH 16GB
Windows 8.1
16:9, 7" 1024*600 IPS

Does it have hdmi? Then connect it to a monitor or tv. What happens if you keep pressing both Vol- and Vol+ and then power on the tablet?
Please send a link to the correct bios, then I can try to make a bios flash package for a usb pen drive.

Yes it has hdmi. I connected to tv. I keep pressed Vol+ and vol- and power on the tablet. dnx mode on the tv. Then, what will i do?
I can't write outside link because i'm new users. [*] is [.]
Correct bios file link:
www*reedertablet*com/reeder/yazilim/reeder_w7ic/bios/ReederW7iC_BIOS_UPDATE_V1.6.8.zip
I want to install android.
EM-I8170 Android Files is here. There is bios file, too. I think for android.

How can i install android to tablet? Thanks for reply.

Ok sounds good. So first thing to do is to flash the original bios/firmware. I will prepare a package in the next half hour. You need a usb hub, a usb stick, a keyboard. Power off the tablet now and try to enter bios menu (press del or escape or f12) and post which bios version is installed. Best is to post a photo. PS: I don't own this tablet and will only help you to recover it with the original bios.

I'm at work right now. I can try them when you get home in the evening. I'll write the results.

Assuming you could enter bios and you have a USB hub, usb stick and keyboard, then you can flash the original bios as follows:
============
Flash new bios
============
1. Connect the USB hub to Reeder tablet and plug in the keyboard and the USB thumb drive containing the new bios files. Power on the device and press DEL or Escape to enter into BIOS.
2. Navigate to "[email protected]", and then choose "Launch EFI shell from filesystem device"
3. After entering shell, type FS?: and then press ENTER
( ? stand for a numeric character. It depends where your USB drive resides, for example, if your USB drive is at FS4, you type FS4: You can always try between FS0 and FS4 )
4. Then type dir and then press ENTER to check if you selected the correct drive
5. Type fpt32.efi -f ReederW7iCBIOS_V1.6.8.bin and press ENTER
6. Type fpt64.efi -f ReederW7iCBIOS_V1.6.8.bin and press ENTER
(PS: you may get an error after either running fpt32.efi or fpt64.efi, but make sure at least one of the flash commands succeeded !)
7. Type exit and press ENTER
8. When you return to BIOS, choose "save changes and reset"
Good luck!
Note1: there is a readme.txt which describes how to install dual-boot Android/Win8.1 on a Voyo A1 Mini (also a EMDOOR tablet). This may be helpful for you to install Android on your tablet.
Note2: if you can't enter BIOS then we must try to flash your tablet using DNX protocol

I tried what you wrote. It installed bios from fpt64.efi. Installation completed. I selected Save Changes and Reset in Bios Menu. Frozen in bios menu. I closed the tablet keep power button. It won't turn on. Now, backlight is off. I think it hard brick. Is there anyone who can help me?

I connected to the tv with hdmi cable. Nothing happened.

Are you sure that bios was the original version? Check if battery is charged and also if you can still enter dnx mode.

İt was original bios file v1.6.8. Battery is full. I can't enter Dnx Mode. I connected it to pc. My pc don't see it m3 or m6 chip also. I think it isn't hard brick. It is Deep Brick.

Try also power on with only Vol+ pressed, alternatively with Vol- pressed. It could be it will then switch to 32-bit mode. Otherwise try disconnecting the battery from the mainboard and reconnect after a minute. If that doesn't help you must buy a flash programmer. There are various at Alibaba for about 30$ with cable connectors for on-board programming.

I tried vol+ or vol- and power button, vol+ and vol- and power button. Nothing happened. I cannot try disconnecting the battery. Because i haven't soldering iron. I think i'll send service it.

Can't install Fastboot drivers - windows 10

Hi all,
So I'll cut right to the chase if I may, don't want to waste your time and I appreciate the help.
I trying to root my 'nVidia Shield Android TV Pro 500GB
The problem:
Trying to install fastboot drivers in order to unlock the bootloader.
Steps & Solutions I tried:
After booting the nVidia Shield into bootloader, when connecting it to my Windows 10 64bit PC , I get a yellow explanation mark in the Device manager.
After getting it, I :
1. Right click on it
2. Choose update driver
3. Browse my computer for driver software
4. Choose 'browse'
5. Select the folder SHIELD_Family_WHQL_USB_driver_201801\SHIELD that contains the .inf file
After doing all of that, when pressing next to install I get a message "The best drivers for your device are already installed", which after nothing changes and fastboot is still not recognized.
Also Tried:
1. In the Browse for drivers window
2. Choose Let me pick from a list of available drivers on my computer
3. Choose Have a disk
4. Browse to the .inf file
5. When pressing next to install I get a message: The folder specified doesn't contain a compatible software driver for your device (The full message can be found in the screenshots attached)
I tried rebooting in driver signing disabled, didn't help.
I have already searched everywhere for the answer, including:
1.The original NVidia Shield Zone
Shield Android TV and Tablet Resource Center
root tutorial
2. https://forum.xda-developers.com/shield-tv/help/fastboot-drivers-t3562822
3. https://forum.xda-developers.com/shield-tablet/help/properly-install-android-fastboot-t3312300
and more... No luck
I'll attach screenshots to show how it looks on my side.
Thanks

Tablet Samsung Ativ Tab3 - XE300TZC Windows 10

I recently wanted to install windows 10 on my Tablet Samsung Activ Tab 3 - XE300TZC-K01PT through the windows update but in the process I had an error in the windows 8.1 installation process that damaged the boot partition.
I contacted Samsung Portugal to request the recovery disk and until today I am waiting for an answer ...
I decided to search and after a few days I managed to get everything worked.
here is the installation process that worked for me!
1 º We need some things.
1- Micro USB OTG (I made my usb otg)
2- Usb hub
3- Keyboard
4- Mouse
5- usb to ethernet (I used D-Link DUB-1312)
6- USB Pen 16Gb
2º We need to download a specific image of windows 10 (February 2016 Windows 10 HOME / PRO) (heidoc(DOT)net) find (Microsoft Windows and Office ISO Download Tool)
3º Make the USB pen boot with rufus(DOT)ie
After the creation of the bootavel pen is completed we need to download and put this on the pen drive :
HD Graphics Driver - downloadcenter(DOT)intel(DOT)com/download/25027/Intel-Iris-Iris-Pro-and-HD-Graphics-Beta-Driver-for-Windows-10
SW Update - [samsung(DOT)com FIND XE300TZC-K01PT ]
Drivers for your network card to USB
On the Samsung Activate tab 3 let's bios (press Power and Volume -) and we need to turn off the secure boot and disable fast boot. do save
We turn off the tablet and we go by the micro usb cable (OTG) + USB HUB + mouse + keyboard + pen of windows 10
We started the power the Samsung activ 3 tab and loaded it several times in the volume - to enter the boot manager
Then we should see our pen drive we created earlier
at this time it is just like a windows 10 installation as on a normal computer.
After installing the PC there are no drivers for the internet card and for this we installed the external network card drivers for USB which mine is the D-Link DUB-1312
We installed the graphics driver - HD Graphics Driver
We installed the Samsung-SW Update drivers and look for our XE300TZC model and downloaded all drivers (1.70Gb)
(DO NOT INSTALL the graphics driver contained in this package)
In the end it is only to do the windows update and install the microsoft office.

Any idea where to get the drivers serperate? I try Windows 8.1 but I have no touch/wifi etc

Hello,
I need just Wireless / Bluetooth device's driver (or just model number's name). SW Update's working or not is depending on the wireless driver. If wireless device doesn't work, so SW Update doesn't work, unfortunatelly. Could you help us on this matter, please? Thanks.

I just downloaded the SW Update on a different PC where I can choose the XE300 and download its drivers, nothing works on windows 10, but at least I have something. You can DM me if you do not succeed to download yourself

Hello, Thanks for your help.
I installed SW Update on another PC as you said. I found the drivers from the model's number. I tried to extract them to the desktop. Wireless LAN Driver is 5,92 MB. But, unfortunatelly it's not extracted to the desktop.
SW UPDATE says "İt's successfully extracted" but it doesn''t extract unfortunatelly.
And also unfortunatelly SW UPDATE doesn't show the Wireless Card's manufacturer's name. But the version number is 3.2.2.3662. If I know the manufacturer's name, I will try to find it on internet. But unfortunatelly it's not shown on SW UPDATE.

I've installed a clean version of windows 10 on my samsung xe300tzc but cant get the touchscreen, wifi, sound and bluetooth to work with many problems showing in device manager. I used the threads in the previous comments but they appear to be dead or of not use. Please can anyone advise where can I get these drivers.

Help for flash with USB-Key YT9216B Chinese Android Head Unit

Good morning all.
I'm trying to flash my firmware but it doesn't work.
I tried more configuration for the usb reader: reader or host but the result is the same.
I reboot with the small reset button and a wooden pick.
here are the pictures of my process:
1: I format the USB-KEY
2: I choose the Firmware and EXTRACT in the USB-KEY
3: I take out the XYAUTO-UPDATE.bin file from the XYAUTOPG file and I put it in the ROOT of USB-KEY.
4: I put the USB-KEY in the reader and I do RESET with the wooden pick.
I get the rebbot but no change to programming the HU and the HU turns on normally then
sets the time ...
5: when I place my USB-KEY in my PC I check the USB-KEY and I see the files "LOST.DIR and Android"?
Can you help me please
I try to redo the firmware of this thread:
https://forum.xda-developers.com/android-auto/android-head-units/everything-yt9216b-t4007063
My pc does not recognize the HU when I connect the usb cable A-A, I don't know why, nothing happens,
then I cannot do the procedure indicated with ATC Flash-tool...
I d'ont remember if there is an USB 4 pin or an USB 6 pin behind the unit, does it matter?
I've been looking for a week on this forum as well as the Russian forum and I can't find the solution

You just have to boot the os with the usb stick(ota zip file and XYAUTO-UPDATE.bin) inserted. It will reboot spontaneously and install the new firmware. You don't have to use the reset.
I wanted to use the pc with spflashtool to upgrade the firmware to android go 9. I don't know if this is possible, cause my device only has 1 gb of ram. I do know if you want to use spflashtool(under download options select both checksums), you have to set it on download, connect the usb and press the reset button. it will start flashing at boot of the device.
A lot of parsing errors, so time for upgrading the firmware.
*edit: systempartition of android 8.1 go seems to be 1.5GB, so the 1200MB of android 9.1 go could very well fit with the 'Download only'-mode.
*edit2: to answer the original poster, there is this topic with a rooted, twrp real android 8.1 rom.
The way to install it is to use spflashtool, connect it through usb with the radio and flash the new rom. So first you have to install the usb drivers(driving signing turned off), then you have to run spflashtool, pick the scatterfile from the rom, and either choose 'wipe and download' or 'upgrade'. Then you select download, the spflashtool vagues, then you have to connect the usb with the radio usb. It should install without the radio turning on. So the radio can be left without power connection.
Just, there might be differences between the yt9216b and yt9216c revisions.

T95MAX Android12 Allwinner H618

Hello,
I bought the android box 12 T95MAX H618, the box boot looped when I received it (it turns on and after 5 seconds restarts).
I managed to get the stock firmware and I reflash it with Pheonix card, but it continues, if I unplug the box or leave it off for more than 5 seconds it boots in a loop.
I tried to connect the ox to the pc with phoenix suit and phoenix USB pro but they do not detect my box, while in windows it detects the box but marks me as an unknown device.
Do you have a solution to stop restarting in a loop?

which Android version? can you show pictures of the tvbox?

the T95MAX runs on android 12, and here is a photo of the model.
and the stock firmware link: https://mega.nz/file/Vpsl1RQQ#pwUFrrZOGTgvzjoUpuoOHiO9dG3UkwWRB5V7bBDaDVU

I can't connect the box to the pc, I use a usb A -> usb A cable.
1 I connect the usb port on the pc but not the boxing and I disconnect all the other cables.
2 I keep pressing the reset button in the AV port
3 I connect the usb port on the box
I hear a sound like what the box are plug and in the device manager I see this:
"Unknown USB device: Device descriptor request failed"
Everything I tried but didn't work.
- Connected turn on usb debugging mode
-All the usb ports of the pc
-Install drivers
Do you have a solution I'm desperate

first thing you need plugin your box again to the computer, then you need to start to remove all unknown usb devices from your device manager, you may need to click on "view > show hidden devices" in device manager to see all unknown usb devices, remove them all, then disconnect your box.
if you have anything in your programs related to drivers for your box, uninstall them before you plug the box back in.
if this is a desktop computer, try to avoid front usb ports if possible.
if you have a second A-A USB cable, test with that if possible.
now before you plugin your box, you need to install the correct drivers, normally the manufacturer or your supplier can give you those, don't download any random T95Max drivers online because there are at least 3 different models of T95Max tvboxes as far as I know, and yours is a newer model.
after installing the drivers, then follow these steps exactly:
- unplug all cables from the tvbox
- plug in one end of the USB cable to the computer only
- have the firmware flashing software open
- press and hold the reset button which is usually placed inside the AV port in most boxes
- while holding the reset button, plugin only the USB cable, then release the reset button
if it's detected correctly, you can move on with the rest of the steps, if it's not detected, then unplug it and repeat the steps but this time plug the USB cable to a different port on the tv box, because not all ports support firmware flashing.
- i'm sure you know the remaining steps since you have the firmware and probably the software for flashing the firmware.
if you try all ports on the tv box and still not working, I would probably still try on a different computer, if that fails as well, then all I could say it might be a defective box, you could maybe try the sdcard method if possible on your tv box, or contact the supplier where you got it from
good luck

first thing you need plugin your box again to the computer, then you need to start to remove all unknown usb devices from your device manager, you may need to click on "view > show hidden devices" in device manager to see all unknown usb devices, remove them all, then disconnect your box.
if you have anything in your programs related to drivers for your box, uninstall them before you plug the box back in.

my box t95MAX is well detected by my pc but in the device manager there is written
"Unknown USB device: Device descriptor request failed"
How to solve this problem?
Maybe I need special drivers?

My friend, this exactly means it's the drivers aren't installed, that's why I sent you the steps you need to follow.
Also you can't say it's well detected if it shows unknown usb device in control panel, hearing your computer making a ding sound doesn't always mean it's a good thing

I bought this same exact box, but my issue has been not being able to install Teamviewer QS nor the Host file. I downloaded that stock firmware image and tried burning it onto a microSD card, but I kept getting failed to load error. After doing further research, it turns out you need to install MS Visual C++ Redistributal Runtimes. I downloaded the all in one file which installs all the Redistributal files.
Then using PhoenixCard Tool (v4.24), I burned the image onto the microSD card. BTW, when the process is done, you'll see many partitions were created on the card. I unplugged the power to the box, popped in the microSD card, plugged the power back in and upgrade process automatically started. It booted back up, screen loaded up all the software and all was running. Teamviewer apps still won't run though.
I wish there was a way to downgrade to Android 11, 10, or even 9. Good luck!
