I did something foolish. I accidentally disabled USB from inside my Chinese Atom-based tablet's UEFI bios settings. With Windows still running I can reboot into the UEFI settings, but with no keyboard I can't work out how to enable USB again. Is there some way to access the UEFI from within the OS? Back in the end of the single-core era for desktop PCs we could flash the BIOS from within XP, so might there be some way for me to crawl through with a hex editor to try finding the variable to change? Maybe there's some software which hooks into the UEFI shell?
Thanks in advance for your help/commiserations.
MB there a way to reset the bios back to default config
ask the manufacture
Fixed. I found a firmware update for the new hybrid Android/Windows version of my Chuwi Vi8 tablet. This contained a dump of the new BIOS (still no touchscreen drivers in BIOS menu though). I then found a flashing utility bundled with a BIOS update for the Onda V820W (which I discovered is very likely to use the same circuit board as the Chuwi Vi8 after opening my tablet and finding an unpopulated micro HDMI socket). All I had to do was delete the Onda ROM from the second download, copy in the Chuwi ROM from the first download and change the extension from .rom to .fd, then run the updater. The same method should solve the issue on the Onda V820W but keeping the Onda ROM. If you (a Google searcher with the same issue) don't want to download 5GB just for the 8MB ROM file, here's the Chuwi Vi8 dual OS BIOS and updater in a package together (this is the BIOS for the 141 209 001 serial numbers, and works on my originally Windows only Chuwi).
I have the same issue, but my CHUWI serial number start with 150 1..... I have to download from needrom.com the rom 2 (Serial 150 100 000) and replace in your folder the file CHUWI.W86JFBNR01.fd and run the updater ?
Sorry for my english
Thanks
Anyone had problem with the touchscreen of the CHUWI VI8 ... after install windows?
The driver was installed, but it is not responsive.

Thank you for this detail, it's very useful and nice to know
I've downloaded the same package ( 5 Gb ) for my Chuwi VX8 3G ( mine is 16 Gb versione, I've downloaded 32 Gb package, the only I can find on that site ) in order to know if there's a new bios version or a bios dump to keep for panic moments :highfive:
But I cannot understand in that package what to look for... And generally, what there's in the RAR file Too many files... How it's possible to copy that files on a USB ? In what way ? And where's the bios ?
followed this guide, bricked mine.
I have S/N 150 9
I have downloaded bios from RU sites, and got video back, but audio is not willing to work.
Is anyone able to reffer me to correct bios for 150 9 model?
Similar story here, but with Prestigio Visconte Quad (PMP880TD). I can access UEFI Shell (and thus run startup.nsh without keyboard), any ideas how to fix it?
UEFI is Insyde H2o, I found that it's possible to modify it settings through setup_var shell command - but for vars addresses I need to have uefi dump. Sadly there's no EFI upgrade released for this device.

Is is possible to delete the Vista recovery partition from hardisk and free the space?
Hi
Have a look at this thread
http://forum.xda-developers.com/showthread.php?t=378890
Should be possible. Remember it looks like it is difficult to get full functionality from an alternative Vista installation so you may not want to destroy this partition unless you have a backup and/or HTC release full downloadable drivers.
Recovery partition
I have used BartPE to boot off an external USB DVD Writer.
From within BartPE you can then use Ghost to capture the ENTIRE drive.
The ***Hidden*** restore partition cannot be see by anything, not ghost, not partition magic, not acronis, it simply is not there.
My belief is that this is due to a BIOS restriction and the FN+F3 boot that does allow the restore is either.....
1. A special mode where the bios can see the hidden partition
2. The actual recovery image is on a separate flash area that we can't see.
Either way having the ghost will recover the hard drive.
I have installed both XP and Linux on the Shift and still been able to reboot, press FN+F3 and do a vista re-installation.
This makes me believe the image is on a separate flash device that only the BIOS section can see.
Hope this helps.

Dude my findings are the same, How did you get XP working did you use the vista drivers? did they work? if not where did you get the drivers from? Please tell as I really could do with a dual boot PC
XP.....
Hi there...
I basically tried installing XP SP2 and then XP Tablet Edition.
Both work great, minus a load of drivers.
You have approximately 800MB RAM free and it flies but you lose all the ability to do touch stuff.
There are drivers i've found out there for the sound/graphics/thumbpad and usb network but others i couldn't find.
As to installing XP it's simple, boot off a USB DVD with XP and just install it, format the entire drive (don't worry it won't see or kill the recovery vista partition if it is a partition, still think it's a separate flash card) and install.
As to the dual booting this is not possible.
I halved the drive using Acronis Disk Suite and whilst it would install, i created two PRIMARY partitions and made the second one bootable.
On restarting i installed XP but then i couldn't get VISTA to boot once i made partition one bootable.
Basically to dual boot XP/VISTA you must install XP first, then install VISTA.
However having investigated this I can find most of the additional software / drivers but the VISTA that is restored is a very optimised installation and just installing VISTA Ultimate or even normal Business may not provide the same experience.
Until we can get access to the RESTORE AREA and get at the image (whatever it may be) I think killing the drive completely to reload VISTA won't be possible.
Our only real hope I think is to get HTC to release XP Drivers (I'm still at a loss to explain why they chose VISTA over XP Tablet Edition). The performance increase with XP over VISTA is quite staggering but the loss of functionality makes it pointless at the moment.
Blitz
Whilst it does provide a much faster overall experience at this time without the driver support it's pointless.
Again Linux is the same, I haven't yet tried installing OSX on it, but that would be even more problematic as Apple don't do drivers for most of the hardware out here that XP / VISTA will detect.
I have resorted to going back to VISTA and removing Origami and a few other bits and pieces and updating to SP1.
I find the whole shift now is much better after installing SP1 and without Origami 2.0 on it.
Hope that helps.

installing Windows XP alongside Vista
I've used the method described in this link to install XP on my U810 as a dual-boot alongside the pre-installed Vista.
http://www.pro-networks.org/forum/about88231.html
blitzspear, what devices were not working in XP besides the touchscreen?
Missing drivers
Everything was missing,
had to download VGA driver from intel. but you lose some of the resolutions.
There is a sound driver and a USB Network device available and the mousepad worked.
There's a PCI device missing and no SD/wifi and chipset.
So basically not a lot works.
Regards
Blitz
IIRC the Raon Digital Everun has the same SDIO Wifi component. Maybe you could try its driver?

All, does anyone have the Pipo W4? It's a lovely little Windows 8 tablet.
Unfortunately in removing the recovery partition my tab decided to stop booting.
The manufacturer's recovery image (and my own) doesn't seem to work.
I was wondering if anyone has this tablet, and if they can, if they can download a couple of drivers I'm unable to find anywhere else?
Thanks.

Lost sound with update
Hi Guys. After days of setting up my cheap X86_64 Chuwi Android box to run PhoenixOS and windows and to boot normally I lost sound after update. I had the hacked 2.0.1 version with gapps and root from a forum on the PhoenixOS website. Sorry I can't post links yet. So somehow someone got sound to work on this device but not sure how they did it. Windows says my soundcard is a Intel SST Audio Device (WDM). So now I have 2.0.2 but no sound. . Any Ideas?
Hey , where to download 2.0.2 32bit ? 64 bit is not working for me , same Problem like remix 64, blisspop 64 and all other Android x86_64 ... Just looping before bootlogo. I dont understand why becorse win 7 and 10 64 also working fine like of all Android x86 32. thanks
Version 2.0 is available for 32b
@wizmart
I know but 2.0.0 is not the same as 2.0.2 i will try it today , but i dont understand why 64 bit is looping while win 64 is working. I hope soon every New Version would be arriveable AS 32 bit , many people i know only can use 32 bit on older PCs.
stucks at a black screen..seems to be a bootloop on my laptop..(amd a4-6210)
tried dual booting with ubuntu and windows..same result
but boots fine on my computer with intel i3 and nvidia card!
can anyone tell me what is the problem and if there is a 32 bit version that will work? i need this for development processes!
hi i have a nuvision windows tablet tm800w610l,couple days ago when windows updates installing blue error screen come and i think say(ssd error) after that windows not booted say(bcd error),so i downloaded windows frimware from website and put in bootable flash and connect with otg to tablet(via simple hub for flash and keyboard)now i have a problem with installing new windows,i think usb speed is very very slow,it cant boot windows for installing(take 20-30 minuts just on the windows install loading screen)after that black screen and nothing happening,im tested other bootable iso files but speed is very very slow i cant do any thing.im searched net some people think its on bios setting,some think usb hub is problem(before that i have a another windows tablet and installed windows via same hub)
so i dont know where is the problem,in bios there is very very settings i dont know which setting must changed.
thanks.
had to reload mine from scratch worked fine with a OTG hub, keyboard , mouse and flash drive .
Got touch working?
image
where did you get the image from?
the one on the nuvision website is corrupt.
I tried new and old versions of winrar and it has checksum errors
same with the drivers. what the f***. tried googleing filenames etc and get almost no results.

Just an FYI, the version that’s currently on the Nuvision website works.
It’s not an iso, at least it doesn’t download as one. I took that file and created an iso and used a usb bootable maker to create the usb drive.
It recognized it upon restarting in advanced mode. The installer is in another language but it got me up and running again.
Just wanted to put this out there.
You can use the NuVision image if you wish (You just extract the RAR to your USB drive and then boot it in your tablet), or you can create installation media using the Windows Media Creation tool (or UUPtoISO if you want to use Insider Preview downloads from another machine).
As long as you use the correct processor architecture, you don't need the NuVision restore package (It's also out of date and no longer supported by Microsoft as it's version 1511, or maybe it was 1603 either way it's unsupported as of now). Some drivers maybe, but a lot of those are available via WU (I've never had to actually install any drivers doing a clean install from a Windows ISO).
This also applies to the NuVision TM800W560L, any 32-bit image will boot and work properly for installing Windows. If you look into installing 64-bit Linux on the W560L though, it's a little more complicated (yes, you can install 64-bit Linux, but not Windows. This is because the Linux kernel can replace UEFI Runtime Services if it needs to, which booting a 64-bit Kernel with a 32-bit version of GRUB causes UEFI to disable access to Runtime Services, which is why Windows cannot run like this and bugchecks with UNSUPPORTED_PROCESSOR.)
Hi all, I've searched online for a solution, but anything, now I've found this section on XDA.
I've used Rufus to burn a USB stick with Phoenix installer iso from the official site, I've installed fine in my hard disk (to get windows and Phoenix separate), but when I try to boot it get stucked on Android x86_64 command line.
My specs are:
CPU: Intel Pentium dual core E5500
GPU: Integrated Intel g41 express
Motherboard: Acer m275 (the Acer veriton mini atx)
I've tried some kernel commands like nomodeset but nothing.
I have this problem with all Android iso, the same error.
Thanks in advance.

Just made an Installation video here on how to do it, downloaded the x64 iso version and burned it to a 16gb USB stick, partition scheme needs to be MBR for UEFI and legacy bios and format as FAT32, etc etc, you will also need parted magic on a seperate USB stick or bootable CD.
Installation for single OS video is here: https://youtu.be/c68qgPepjFI
If you want a dual boot, Windows and Phoenix, then boot into windows and use the downloader, the iso is for single OS only or Live CD/USB.
