Is it possible to merge this with the Windows C:\ Partition? And which ones can I delete? Everyone except the C:\ + EFI + Restore?

Please confirm!
[Teclast X98 Air 3G] Mikha777:
If you upgrade to Win10 after the installation if you do an "image" backup you can also delete the recovery partition if you don't intend to downgrade on Win 8. Keep the system & UEFI partition.

You can always expand the partition after the Win10 Upgrade too with "Partition Master" :o
[Teclast X98 Air 3G] tecknight:
joq3,

If your aim is to have a Windows only tablet, Do not remove the first EFI partition, which is partition 1.

Everything else can be removed, either before booting into the windows installer (if you are using an automated install, such as a .wim file) or during the install (if you are doing a manual install) During a normal non-automated install, Windows will ask where you want to install to. It will then bring up a partition selector. Using the selector, you can delete any partitions you want to and select the unallocated space as the target for the Windows install.
[Teclast X98 Air 3G] pedralpi:
I cannot help , but I have the same eventos and like to understand it !
[Teclast X98 Air 3G] joq3:
F**k!!! I did remove all the android partitions, including the first, as Mikha said it was okey. What happens now? It does boot and work normally.

I will use the .wim automated installer. So i need to expand the system partition before.

But I am not able to expand the system partition as the android partition is on the left of the system partition. How do I move it to the right beside the other unallocated space?
[Teclast X98 Air 3G] dastimlein:
is there a win10 iso (especially German or englisch?)
[Teclast X98 Air 3G] tecknight:
It's OK, You can still add the ESP partition if you want to. I would recommend keeping the ESP partition,

but if you are still able to boot into Windows and you have no ESP partition at all and you never plan on installing a second OS, you might be able to live w/o it.

The only way to make your partitions all contiguous is to delete them prior to the Windows install and let the Windows install recreate them.

I have created an MFT image to restore the EFI partition.

Let me know if you want toi do it.

The image will also remove any existing partitions, so you would be ready to clean install Windows.
[Teclast X98 Air 3G] joq3:
Yes sure! But what does this partition do? Check the image i posted, there is one efi-partition, is that it? It does work as it should.

Please do that, thank you!
[Teclast X98 Air 3G] tecknight:
Yes I see that you have the Windows EFI partition.

That partition is not actually needed.

Non Teclast dual boot tablets don't have the Windows EFI part at all.

When my Windows 10 stopped booting and I had to reinstall, I deleted all of my Windows partitions, including the EFI.

The Windows install then used all available space, but only created 2 partitions instead of the 4 or 5 that I had before.

and both Android and Windows are working perfectly.

Your problem is, you have a bunch of empty space, then your Windows parts.

Unfortunately you cannot do an upgrade of Windows, you must do a fresh install and blow out your old partitions in order to use all of your emmc,

Does that utility you are using have the ability to move a partition ?

If it does, I would say move your Windows EFI to offset 0 (not actually 0, but at the first available slot after the partition table itself), the very start of the emmc., then delete the other Windows parts and do your install.

This is an MFT flashable image that will repartition an X98 and create only the first ESP partition at the beginning of the drive.

http://xdaforums.com/attachment.php?attachmentid=3479961&stc=1&d=1442742472

You could flash this image, then immediately install Windows into the huge unallocated space remaining.

or one other possible wildcard option.

You could install Windows into your existing partitions and turn the huge chunk of unallocated space into a new NTFS partition. You could map the NTFS partition to either a drive letter or to a specific folder on your C: drive

You cry for nothing since your EFI partition and system partition are always there if the EFI partition was not there you could not been able to boot the tablet at all . https://en.wikipedia.org/wiki/EFI_System_partition :p

Relax it's the Week-end ! :cool:

---------- Post added at 10:17 AM ---------- Previous post was at 10:04 AM ----------

Now you just have to add the unused space to the "main partition" and you're done ! Don't forget to make an Image Back-up after this way if something wrong happen in the future you will be able to start from "today" ;)

after clean install of windows 10, my mobile broadband option is missing.

appreciate if someone can show a screenshot of the network connection/adapter page to see what i am missing

GPS doesnt work as well, not able to get location. geolocation sensor device in device manager is missing.
[Teclast X98 Air 3G] tecknight:
I don't know what you told him, but IF you told him to delete the FIRST EFI partition., that was probably not the best advice..

If he had left the first EFI partition there, he could have deleted the second one and his Windows partitions and could have already completed a clean install of Windows with it using all available space on the tablet. As it is now, he is going to either have to figure out a way to move the existing EFI partition to the start of his emmc, or he is going to have to repartition the device and recreate the first EFI partition in order to use the entire emmc for Windows.

It's not earthshattering to be sure, but it will probably take quite a bit longer before he is done.

---------- Post added at 08:36 AM ---------- Previous post was at 08:32 AM ----------

jagr,

Did you install all of the Teclast drivers ? I am pretty sure I had to manually install my GPS driver at the very least.

Have you checked out Windows Device Manager to see if there are any unrecognized devices ?
[Teclast X98 Air 3G] jagr:
tecknight, yes i did install all of teclast drivers and tried the different sets of driver there were available as well. there were no unrecognized drivers and somehow the GPS geolocation was not in the sensor list.

i was able also able to find and install the comneon suspend modem drivers but i could only use it as a dial up connection instead of the mobile broadband option which is much better way to connect.

anyway i am redoing the whole thing now as i was trying to get it back to factory condition and upgrade from there but failed. so will be a fresh clean install of windows 10 again.

am on c5j6 version. will post a screenshot once i am done if the issues remain.
[Teclast X98 Air 3G] tecknight:
Here are the devices

The CDC MBIM is the mobile data

The Broadcom GNSS 4752 Geolocation Sensor is GPS

FYI: I don't use a SIM, so I can't confirm mobile data is working, but my GPS works great.
[Teclast X98 Air 3G] jagr:
thanks. dont seem to find the cdc mbim in all the drivers package. possible to extract it?

i'll try installing the gps first thing.

I get this error when trying to install this:

Making directories...
The system cannot find the drive specified.

"Failed to make w:\recycler\scratch directory"

An error has been detected.

And then it stops the script, nothing is installed. What can I do?

I tried installing a normal Windows 10 first, and then do the WINPE-install, same error. So I removed all partitions and kept one partition only (NTFS). Same error.

I use two USB, one FAT32 with WINPE and one NTFS with the images.

Any ideas?

[Teclast X98 Air 3G] Mikha777:
It could be related to firmware from what I know for

some

Hi everybody,

This week, I knew Teclast has a new X98 PRO international version different to the sold one from China. They closed a new International version for EU specially. So, it looks like, they will have 2 international versions. They will launch the new one on Sept 27Th and this new version has not Chinese apks, it has new apks, several new free accesories what I do not know yet, European warranty,…. I work in a media in EU and we received it. They will sell from Spain to EU (teclast.es) as I can see on teclast.com. Upon my point of view, this step from Teclast is very, very interesting for EU people. I will pay attention to teclast.es in order to see the new presale.

[MENTION=2695164]joq3[/MENTION] Does your main partition on x98 is Fat32 ?? If not it could be UEFI related... :eek:
[Teclast X98 Air 3G] tecknight:
I am not assuming anything.

I am just respecting what joq3 said and he said you told him it was ok to delete the partition.

The way I see it, there were 2 people involved in that discussion and their recollections are in conflict.

---------- Post added at 10:45 AM ---------- Previous post was at 10:42 AM ----------

Yes, 1.03 will consume about 3 times as much battery in sleep mode compared to 2.02

---------- Post added at 10:48 AM ---------- Previous post was at 10:45 AM ----------

The only thing you changed is your OS, correct ?
[Teclast X98 Air 3G] tecknight:
Ok, the Broadcom GPS drivers are here:

http://xdaforums.com/attachment.php?attachmentid=3480514&stc=1&d=1442772666

There is also another device under System Devices called Broadcom GNSS bus driver - 4752

and the CDC MBIM driver is a Microsoft driver, so it may be a standard driver that is part of Windows.

Partition - space wasted

A couple of days ago I wrote that even though I used the script to have a partition / cache 100MB instead of 1GB, I have curiously

the partition / cache equal to 1GB

-

Today I installed Win10 on the partitioner Aomei (like Esaeus) to understand how it is structured the device. I realized that I have a number of partitions of several tens of MB do not know if they are useful to Windows or Android, and partition /cache, of 1 GB that.

These small partitions 16 or 64 MB are part of the structure of an OS ? Which ? If not you can be added to the android partition ext4 /data, or to the Windows partition?

I can do the same thing with the partition /cache? It is risky?
[Teclast X98 Air 3G] tecknight:
Krel,

Here is some documentation for the partitions:

Reference: Teclast X98 Air 3G 64GB dual-boot default partition map

The first 15 partitions are used by Android

While there are 2 or 3 of them that "may" not be being used by Android, they are small enough that I don't think it's worth the risk of crashing Android for less than 100 MB of space.

FYI, the 3 partitions that I suspect are not being used at all by Android are:

reserved

reserved_1

[Teclast X98 Air 3G] mihaiolimpiu:
No, the Viva is X98 without Air... you will brick your device. There is another tutorial on 4pda on how to install windows or Android without dualboot.
[Teclast X98 Air 3G] tecknight:
I would just create a bootable USB key using the Microsoft Media creation tool, connect it to your X98 and go into BIOS and set it for boot override

When it boots up, delete every partition except your remaining ESP, then tell Windows to install to the unallocated space AFTER the ESP partition.

Let it install, then install the Teclast drivers and then turn the remaining unallocated chunk into an NTFS partition.

It won't require 3 different USB keys that way, only the 1.

I know it will work this way, because that is exactly how I reinstalled my Windows 10 about 4 days ago.

Its either going to have to be that way or you will have to completely reformat the drive and recreate the first ESP partition using MFT
[Teclast X98 Air 3G] kRel:
I understand perfectly. Thank you. I will not touch anything.

however, partition Table you've linked, correspond exactly to my partitions, with the exception of that from 450MB that I'll find out soon what is.

Thank you. Hi . . . .
[Teclast X98 Air 3G] Mikha777:
Windows ONLY use Fat32 or NTFS

anything else is related to the Android

[Teclast X98 Air 3G] kRel:
Exactly ....

also [MENTION=2651082]tecknight[/MENTION]

Now, I have just discovered that the 450 MB partition is a win10 recovery partition that perhaps is also possible to remove, but I leave them for prudence ...

Thanks :)
[Teclast X98 Air 3G] Mikha777:
To help you WRE = Windows Recovery Environment Partition) and ESP = EFI System Partition.

The 450 mb partition is the Windows Tools in case of Crash ao you must keep it but the other 4.69 GB is an image and you can delete it if you want more space BUT have an image backup in case of crash.

If you are don't "feel safe" about deleting them just rename it first and reboot the X98 and see what happen in the worst case the X98 will not boot so you will have to use the WinPe (32 bit) USB boot of Aomei Partition to rename it the original name ;)

[Teclast X98 Air 3G] Spectator_0o:
Hey mirek190, if I want to upgrade from your v4.2 Android 4.4.4 ROM to the v5.0 Android Lollipop ROM, can I Titanium Backup a few apps I've installed and restore them after the upgrade? (Obviously I'll make sure the backup files are moved somewhere safe as I'll be doing a wipe and install)

Or is there a problem doing this with apps backed up in 4.4.4. and restored in Lollipop? Currently have extremely limited internet and don't want to download some of these apps/games again due to their size.
[Teclast X98 Air 3G] jagr:
alright sorry its a firmware issue. mobile broadband and gps works fine in windows with 2.02. camera not working in android as reported.

in 2.05 camera works in android but mobile broadband and gps does not work in windows. workaround for mobile broadband is to install the comneon modem drivers and use it as a dial up connection.

dont know if this will save battery more as you dial on demand rather than mobile broadband which always detects the ISP signal even if its not connected.

thanks guys!
[Teclast X98 Air 3G] Mikha777:
When I will have completed the test for the Front Camera in Bios 2.05 in Windows ( I use only Windows) if you want test it I can try to solve the BCM4752 = GPS issue under Windows with 2.05, let me know if you could be interested.

short question: Can your lollipop rom for TECLAST x98air3g be used for a chuwi hi8, too?

Because the hardware are closed. If I search for 'chuwi hi8 + lollipop' I always get your rom as result ;- ) I'm very very closed to test it. hehe. The small linux distribution gparted runs already perfectly (just for test). Unbuntu is not a solution yet (later). And windows doesn't make sense with 32 GB HDD (or use win without apps. hehe) .

[Teclast X98 Air 3G] joq3:
Hi tecknight, thank you for helping me out.

I gave up on installing the .wim from Teclast, and installed Windows 10 the usual way.

Tablet boots, and works great (only Windows).

And before I installed Win 10 I removed all the partitions on the drive and let Win installer create the necessary ones.

What I don't understand is, what is this ESP-partition that you are talking about, that you tell me to flash with MFT? As the tablet seems to work normally, boot normally and everything, so what does this partition do?

I removed all partitions with GParted, so there is nothing there, yet it works great?

Is the Android 5 lolipop rom we use vulnerable to the long password attack?

http://www.engadget.com/2015/09/16/android-lock-screen-bypass-flaw/

Are we going to be seeing an Android 5.1.1 rom in the future?

Also does any one know if the 2.05 bios do anything for Android? I can't believe the amount of Windows 10 posts we get here now.. Windows 10 on my Tablet just sucks for basic usage of things I have normally done on my iPad or Android boot of my X98 Teclast..

For example in the Windows 10 app store there is the great "TuneIn Radio" app I think 'great, some of the good apps are in Windows' I start listening to the radio and its constantly cutting out and then it finally just gets stuck in a weird loop playing the last 20 seconds of radio over and over, I leave it for like 10 mins and it just keeps doing it... **** windows 10..
[Teclast X98 Air 3G] tecknight:
First, let me say I am very happy you got Windows installed and using your entire emmc.

You will actually have even more available space that way, but I do recommend that you create a recovery bootable USB, just in case you have Windows problems somewhere down the road.

Instructions are here:

https://www.winhelp.us/create-a-recovery-drive-in-windows-8.html

(never mind the URL, the instructions cover Windows 10)

The nice thing is, the recovery USB gives you the same functionality and frees up almost 5GB of emmc space.

#2 EFI partition: MY understanding was that an EFI partition was necessary to boot a host OS on a system with UEFI BIOS.

I will do some more research and get back to you.

Maybe it's only required for multiple OS support.

I am pretty sure [MENTION=3986785]Mikha777[/MENTION] said just that earlier today and quoted a wikipedia link

embedded unique Windows 8.1 software license key

OK let me get this straight: This update here is just updating the Bios and not the Windows nor the Android partitions.

But it will remove the embedded (unique) Windows ID and this might create a problem down the road wen trying to install Windows 8.1.

Question: Would this have an effect on a already upgraded Windows 10 partition? Reason: I extracted the software key in Windows ten on the tablet and tried to re-insert it as the unique key. The key was rejected by the system as not acceptable.....

Now, what are the consequences on running the BIOS update. I feel the need for it to make the pad more usable, yet if I remove the ability to run windows...

[Teclast X98 Air 3G] tecknight:
Matt,

There was another person with the same problem as you who posted this issue about 3 weeks ago.

I am running the same Android ROM as you and my SDCARD has always worked perfectly in both OSes under both Windows 8.1 and Windows 10.

I am using a SANDISK 64GB MIcroSD formatted into 1 64GB NTFS partition

Matt: Just noticed the errors you are reporting.

Try formatting it as NTFS: it should clear up the errors

---------- Post added at 05:53 AM ---------- Previous post was at 05:35 AM ----------

If you have already upgraded to Windows 10, the key isn't even being used any more.

The BIOS flashing script doesn't remove the embedded key, it just flashes a BIOS image with a blank key.

As long as you have the correct key (it doesn't HAVE to be in the BIOS, you can type it in during the Windows 8.1 install, you can install and activate Windows 8.1.

There are several reasons I didn't include trying to re-inject your key back into your BIOS in the tutorial:

1. The program that can do it is entirely in chinese, has multiple dialogs and is very confusing.

It will not work on an english system without modifications.

2. Every time you alter your BIOS image (including changing the embedded software key), there is a chance of bricking your device

3. The only difference between having the key embedded and having it on paper or in electronic form is that Windows 8.1 installer will automatically load the embedded key. Once you enter the saved key into the installer, it functions exactly the same.

4. Once you have upgraded to Windows 10, the software key is useless.

However, if you want to research how to inject your key, alter the Teclast program, decipher the chinese menus and inject your key, risking the possibility of bricking your system all for the sake of not having to type in the software key during the Windows 8.1 install, be my guest.
[Teclast X98 Air 3G] hbeil:
Got it - thanks

.

Ok thanks.

I think you are right, inserting the key is not worth the hassle. Especially after having moved on to Win10. BTW a move that I can only recommend on the Teclast Pad.

Thanks, Hartmut
