Please help recover Teclast X89 Dual Boot - Android Q&A, Help & Troubleshooting

I wanted to reflash Android after unsuccessful Xposed install and accidentally used the wrong file in the Manufacturing Flash Tool.
I now have no Android, no Windows -- just BIOS and fastboot are functional. When it boots normally all I see is a UEFI shell with the list of partitions.
I've tried using MFT with the correct file and it didn't help.
I think I need to set up proper (dual-boot) partitions thru fastboot and only then try flashing Android again. Can anyone please help?

Android flashed just fine once I switched from a Windows XP running in a VM to a laptop running Windows 7 64bit.
I'm having problems rolling over the Windows image, I'm guessing it's because I've messed up the partition table -- it can't find the drive with the images now. Anyone had that?

Mediapad 10 FHD root and custom recovery

Hi All
I got myself a Mediapad 10 FHD two weeks ago, 1.2MHz 1GB Ram, 8GB Rom, Wifi.
It looks like I cannot get root nor custom recovery installed on the device. I have tried all I could find so far, without any luck.
What I have tried so far is:
Hi Suite Setup v1.7.00.1006
Hi Suite Setup v1.8.10.1506
custom USB driver from Team Android
standard Linux ADB driver (which work on my Nexus 4)
Windows XP in a virtual box running the driver above
standalone Windows XP computer running this drivers
toolboxes for ADB / root
Genotools v2.0
Root with Restore by Bin4ry22
auto recovery installer for huawei mediapad
root with repair
Genotools seems to work for some people, no luck here.
When I follow the steps for root manually from a Linux console I can move all the needed files onto the device but cannot change permissions or dont have access to the desired folders.
The weird thing is that that I cant access the device when in recovery at all, while access with ADB debugging is ok.
adb reboot bootloader boots the device into recovery
afterwards fastboot devices doesnt show anything
fastboot flash recovery cwm.img just waits for the device forever
Anybody have an idea what else I can try?
Recoveries in that installer are ONLY for 7" mediapad (hws7300)

Lenovo p780 can't do anything after wipe

I have a problem with the phone, it all started with errors com.lenovo.email error, then launcher was not open. I was decided to do a factory reset, but after resetting the error persists. Then I ran the wipe command in the terminal. Now I can't install any of the firmware, the phone can only see it in restore mode - install from adb. In my Mac I see only:
List of devices attached
0123456789ABCDEF sideload
I tried to download the firmware on adb sideload, but got a simple answer - error.
Also Im trying to soft reset phone, pressing red button under back cover.
I don't have a computer with Windows, only Mac OS and Ubuntu.
Can I recover my phone?

Pc no longer booting to windows

I have a Dell Laptop running windows 10 and boots via UEFI. I have installed Remix OS beta (64 bit version) several times on the HDD using the Remix program available when downloading from their website. Apart from one occasion only, Remix usually hung and I remained patient, waiting for a version that would work. That happened with the latest version (2.0.403) i.e Remix finally works and the OS boots up normally. However (as is usually the case with life in general) whilst Remix works, when selecting windows from the Grub loader it says that it cannot find the path to windows and I cannot boot into windows. I appreciate that this is a Android forum but this problem is specific to Remix I think and some entry in the grub loader and as such I turn to this forum in case anyone has any ideas so that I can fix the grub loader or whatever and be able to boot into windows - I am of course happy that I can boot into Remix but I also still need my windows!
Thanks a lot in advance
Andrew
did you installed them in 2 separate hard drive?
and your computer use bios or uefi.
if it is uefi you should check if the old windows boot loader is still here.
and if it is 2hdd you should boot directly to windows hard drive. by changing your boot settings.

Thanks. They are on 1 hdd and it is UEFI. I don't know how to check if old boot loader is there but I have tried the repair option on the windows CD/USB including repair MBR without any luck. So I think the old boot loader is gone and replaced by Grub.

to see if the bootloader is still here you should go to your uefi and boot option.
it is generaly holding del while booting to acces it.
you should see in boot windows boot loader and grub.
you should be able to switch them
if your windows installation is not gone.

Thanks. On the Dell laptop it is F12 and there is an option under UEFI BOOT to choose Windows Boot Manager but selecting this goes to the Grub Loader. I need somehow to edit the Grub loader to point it back to where windows is residing unless Remix has deleted the windows partition??

Many thanks although this did not work. Clearly something went wrong when Remix was installed but I cannot understand what exactly. Anyway, I feel that I should not trouble this forum further since it seems like a problem now more to do with a corrupted Windows or Grub Boot loader issue than a Android issue. What I was hoping in particular was that someone had had the same issue after installing Remix and how therefore they dealt with it but it doesn't seem that this is the case. Looks like I am the only (un)lucky one!
Thanks again
Andrew

UPDATE: I placed a Windows 7 installation disk in the laptop and turned it on (as I had read that trying to use the bootfix from a USB may not work). The laptop then started to boot windows 10 normally and by-passed the Grub loader! I cannot explain how this is possible but once Windows booted I uninstalled Remix. I rebooted and the Grub loader was gone. I then installed Remix 3 (as I am a sucker for punishment) and the new Grub loader works fine - the laptop now boots into Windows & Remix!
Thanks for those who replied
Regards
Andrew

ASUS MEMoPad 8 - Aaargh...

Hi folks,
I am a total newbie to sorting out tablet problems.
My MEMoPad 8 "bricked" a while back and, try as I might, I cannot get it to recover. I had not "rooted" it and now, it is stuck on either the normal boot screen or I can get into the Droidboot screen - but I cannot enter commands such as
fastboot flash system system.img or
fastboot flash boot boot.img.
What should I do? I have followed, as far as I can, the directions on "post58341834".
I don't have a PC running Windows - my options are either a PC running Linux Mint 18.3 or a MacBook Pro running MacOS 10.13 (High Sierra). I can get into a "terminal" but that is where I come to a horribly grinding HALT!!
Can someone take me through what needs to be done, in a "step-by-step" fashion, please? (Be gentle, though...!)
