New base C9J7

Insufficient Storage Space for Google Play Service Update.

I've been experiencing this with the Stock Rom installation (500M partition setting).

It seems that the current Google Play Store Fix package has been out-of-date with Google Play Service.

As I tested Hangout, the system required the update of the Play Service which might need some huge extra space for the installation from the store.

After I deleted almost all pre-installed apps and system apps on the Stock Rom, I could barely update Google Play Service.

It's weird though I think 500M partition for Android seems not ok if you're a heavy Android user. :rolleyes:
[Teclast X98 Air 3G] jcespi2005:
If you're talking about system partition, 500Mb could be enough, cause is Read Only, but for Play Store fix you need to move APKs to system partition, so expect a bit increase... or you can test the Lite ROM C9J7 i post yesterday, with Play fixed.

If you're talking about Data partition, sure 500Mb is not enough. 2 to 4Gb should be. Data partition is used for data aplications, but for aplications installed too, so is normal 500Mb is not enough. Try to use Link2SD in combination with FolderMount, this gives you the best to reduce DATA partition ;) But use a good SD...
[Teclast X98 Air 3G] kinhvanhoa:
Thanks for the detailed explanation. Well, when I tried your Rom the other day, "Google Play Services" caused some error message and it didn't even ask me to update 'google play services" on the store. It worked anyway though .

Now with the stock rom (rooted, Google Store Fix applied, then the play services updated) seems working fine except the horribly small "storage" to download some apps from my backup apps on the Google store.

These days the size of apps are getting bigger and bigger. Over 40 Mb apps become common.

I think Link2SD would be a good solution. I already uses Class 10 SD on my device. But for the system partition, I am still wondering that 500M could be enough. I don't play any games on my device though.

After I installed Google Plus, Hangout and Facebook app, my device is already full with the internal storage.

(See the attachment.)
[Teclast X98 Air 3G] ImJamIN:
So you are telling me that 2gb after data isn't enough? Or are you speaking that 500mb of /system partition isn't enough?

Where are you installed g+ hangout and Facebook? As system app?

Oh man... I was only writing about the necessity of HW dump! You are telling truth that SW dump are faulty but there's no need of HW dumped BIOS (have you done it BTW? why you claim that it will work?) because as we have seen with dual boot bios, chinese can repair SW dump.

Suma summarum:

- pure SW dump will brick your device

- well prepared SW dump works (like our first dual boot bios)

- noone has tried to perform a HW backup so we don't know if it will work

[Teclast X98 Air 3G] Hendrickson:
Damn! How did you do that, I was really worried about frying my one to. I read on the Russian thread that the voltage of the usb programmer was more than the chip is meant to handle. But since he said it worked I had nothing to loose and went for it. I guess we were lucky? Or it could depend on the chips if they handle the extra current. Glad it worked as I would hate to have to solder and resolder that small winbond eeprom. My solder skills are not the best.

You have the dual boot option, but honestly it has it's faults. No bios options, no sleep, Windows clock issue and its just not as stable. I recommend to stay on Win 8 until we have a better bios from Teclast. Another thought is flashing the Air II bios, in theory it should work, but it has not been tested. It could render your modem dead or worse.

I'm running on my c6J7, just seems the best to me after my c6j6 has a slow touch screen and dual boot is average. I have discovered that my Air 3G c6J7 has much louder sound output. No complaints about the volume unlike my C6J6. Could be drivers I think, bios or hardware?

Echo of OKQI (Authorized Teclast seller) send me the link for the X10HD, http://www.aliexpress.com/store/product/Item Title/609719_32255560453.html

It will be sent at the end of the month. 2560 x 1600 with 299PPI would be nice, but the narrow 16:10 Idk. 64GB is a plus. The price is $299. Might get one for review only.

Winbond 25Q64FWSIG is the original with 1.8V (according to the datasheet) and one of the possible replacements is 25Q64FVSIG with 3.0V. So please be careful when programming with different devices.

I confess, that I don't know practically anything about these, just googled and bought some devices and chips.
[Teclast X98 Air 3G] kinhvanhoa:
The partition (500M) with the Stock Rom which I removed almost all Chinese system apps by Link2SD.

Practically, with 500M partitioned internal storage, roughly Facebook (damn it!) occupies 112 MB, Google Plus had 80MB, Hangouts 30MB, GMAIL 30MB, Play Service 76MB, Play Store 20MB ...etc plus probably around 150MB android system.

What could we install more on the device with 500MB internal storage? :(

if you format the card as fat32, both of OS will able to see it. the rest is just up to you. but some of apps (especialy in android) want to be installed as system app (in internal memory) and it can be sometimes trouble when you install them on an external card

Questions about Partitions allocating for Android and Windows

In my experience to install the Dual Bios system on Air II (HG6M), 500 MB internal storage for Android 4.4.4. seems too small for using apps. If someone prefers to use Windows 8.1 more, it would be ok though. People like me who are more inclined to use Android Apps on mobile devices would feel constrained by the shortage of the storage although some app data could be relocated to the SD card by Link2SD.

Now MSOFFICE apps are even available on Android. I don't think I should use Windows for heavier performances except some Windows only programs.

Then, my questions are:

1. How much space is necessary for Windows 8.1 pro (the images with Bing and Pro on the front page are gone. The links are broken) such as the OS and caches ?

- Windows system certainly doesn't allow programs to cache some data space on the external SD card like Android could be. I will definitely assign the larger partition for Windows 8.1.

2. My android phone uses about 2 GB internal storage for Apps currently. Would it be possible to assign 3 GB internal space for Android on the Dual Bios system?

I am a bit exhausted to start over from the Dual Bios to Windows to fix Google Play stores (hopefully to fix the camera problem on Windows sooner or later). I at least make sure the best partition allocations for the follow-ups in future.

Thanks.
[Teclast X98 Air 3G] jcespi2005:
i do this config for me:

Android: 5Gb data partition, 1Gb system, 512Mb cache (using my ROM)

Windows: the rest 23Gb.

SD: 32Gb partitioned with 26Gb FAT32 for shared win and android, and ext4 partition for Link2SD on Android (to move some big apps or app data).

---------- Post added at 02:34 PM ---------- Previous post was at 02:32 PM ----------

You can install apps on a FAT32 partition on SD from Windows. The point of having diferent partitions is limited by teh fact windows can't mount more than one primary... so take care of this when doing. Perhaps you can make the NTFS primary, a FAT32 extended, and ext4 extended too... but need to be tested.

I finally build working rom rot x98 air 3g .

Included play store, youtube, google services, tts from google ( not that ****ty pico tts ) normal keyboard , adblock, screen dp, chromei , etc

But I have still problem with root - I changed even boot.img but still not fully rooted....
[Teclast X98 Air 3G] kinhvanhoa:
Thanks! Could you share " partition.tbl " file ?

Could you explain more about the SD card partitions? On the front page, it was advised that I should format my Micro SD card by FAT 32 only for the windows installation. Is "ext4" partition made by Link2SD ?

Thanks.
[Teclast X98 Air 3G] jcespi2005:
You can take the TBL from one of the links on http://xdaforums.com/showpost.php?p=57548274&postcount=3196

Link2SD don't make the partitions, you need to use a program on PC (linux or windows) to make two primary partitions...
[Teclast X98 Air 3G] kinhvanhoa:
I see. I once tried EXT4 partition on Android phones but as I remembered the EXT4 partition should be allocated on the recovery mode if it can be recognized from booting. A bit confusing though. I will try to partition 32GB first anyway.

(BTW, why does the front page instruction suggest 500 MB for the android system? The TBL file among Chinese ones has 5GB as default though. Perhaps too much concerned with Windows system. ;) )
[Teclast X98 Air 3G] jcespi2005:
No need to use recovery for SD being recognized by the system, just partition on PC (Grupb or Partition Magic) and insert on Android, as soon you execute Link2SD, see the second partition, and ask what type is, choose ext4, and reboot.

In the TBL modified by me 500Mb is assigned to cache partition (default 1Gb). 5Gb is data partition and 1Gb is system. 500Mb for system is a bit low, sure we need to "lite" more the ROM to make it 500Mb fit.

Just wondering if it is possible to dual boot on the Air II (HG6M)? has this been tested?

And what is the latest non dual-boot bios that would work on the HG6M? do the bios from the air 3g C6J7 work on the HG6M? of course I'd never try flashing such as I have no way of recovering if it bricks, just curious if anyone has delved into it and tested to see if these things are compatible as the hardware is pretty much identical no?
[Teclast X98 Air 3G] ice.man:
Partitions

If you don't have a gpt disk and a uefi bios, old MSdos partitions works like this:

TWO options:

_4x primary partitions (just 1 active)

or

_3x primary partitions (only this will accept active/boot flag) + 1x Extendend (containing up to 64 secondary partitions - NON can be active/bootable)

.

External SD usage in Windows (partition must be NTFS formatted).

since WinNT hard and symlink can be used.

Starting from the internal disk (ex c: partition), you can either create a link to a directory in the sdcard (the name must not yet be present in the actual mother partition in C: es >mklink /d C:\NewFolder F:\test\folders\NewFolder

or

you can extend an existing partition to a partition in sdcard. For example you can extend the ProgramFIles dicectory of C:\ to take advantage of free room available in the SDcard es >mklink /j C:\ProgramFiles F:\test\folders\ProgramFiles

I have compared the dual bios that came from Chinese man, and the one that a user posted yesterday.

Both are software dumb.

The one of chinese is mod for work with c6j6 (and all the other version of x98), but it seems that the code is already modded with the one that is dumbed from a users yesterday.

So, probably the new c9j7 bios that was dumb with software is " OK " to use.

But we could be more sure if someone that have the tools for program the bios via hw, try this new one and see if it's work.

If x98 brick, he can reprogrammer his bios via hardware

Can someone try this test, may be I done something wrong.
[Teclast X98 Air 3G] pcbroute:

[Teclast X98 Air 3G] Hendrickson:
I guess I was lucky, I just used the flasher as is and all was okay for me.

Yes, my Air II is running dual boot I'll upload video proof soon that it's fine and works. I used the same dual boot bios and flashed it running the bat file from Windows. 100% non brick.
[Teclast X98 Air 3G] kinhvanhoa:
Did you fix the camera upside-down (and the screen upside-down) problem on Windows?

If so, which widows IMG or drivers did you use?
[Teclast X98 Air 3G] Hendrickson:
Yes I fixed that. I had to mess with the drivers a bit. I used the supplied drivers here. I did have the screen correct way up in landscape, but inverted in portrait. The fix was using the reg fix in the gsensor folder.
[Teclast X98 Air 3G] 25gee:
This, also is this dual boot bios only working because it has been tweaked and edited such that it works on all X98 devices? or can you literally take a bios designed for say the C9 and it'll work on most X98 devices because the hardware is the same?

This is why I'm curious, if one bios can be modified to work on a multitude of devices why can't we, if for example a new bios is released for one device say the x98 Air 3G that fixes an issue present on the Air II aswell, have it modified to work on both devices to fix said issues? just curious as to whether or not this is possible and what limitations apply since the hardware is almost identical no?
[Teclast X98 Air 3G] kinhvanhoa:
That's what I've been thinking too about the Dual Bios matter. Since the Dual Bios is not officially offered by Teclast, there is no choice to test the possible candidate of the universal bios until some Chinese guys develop the proper bios for a specific model such as AIR II (HG6M). Anyway, I found that the stock Android Rom for HG6M is working as smooth with the dual bios although I have a partition problem which I am fixing now.

---------- Post added at 12:15 PM ---------- Previous post was at 11:57 AM ----------

I tried more than twice with fixing the problem with the drivers available here. First time it seemed worked but in the latest attempt, it didn't make any changes. I am trying one more time now.
[Teclast X98 Air 3G] Hendrickson:
What are peoples thoughts on dual boot on these devices? I'm still messing with the Air II on D.B. and have found the follow:

Powering on issues sometimes, seems it doesn't shutdown correctly.

Both OS's seem a bit slower than if there were just Android or Windows.

Android takes much longer to shut down.

Android the eMMC is much slower than if it were just the single OS maybe its all the partitions?

Windows really need more than 8-9 GB free for installing games or apps. (Windows update eats up a lot)

Sometimes it will just boot straight into Android and never gave me the chance to select Windows (No dual OS selection screen)

Slower boot times

Sometimes I have to hold the power button for 10 seconds and then power on.

Minor annoyances, like Windows time gets screwed up.

All in all, I think the concept is okay, but looking at the negatives. Not sure it's really worth it. With the X10HD having 64GB I'm sure it will be better overall and more refined dual boot for Teclast. But is it really worth it !?!?!?!? :eek:
[Teclast X98 Air 3G] jcespi2005:
For the windows update there is a workaround to delete all stuff downloaded to install... Google for "winsxs delete" ;)

The slow boot, I can't see much difference on C6J6...and eMMC is not slower on android, copying or moving files seems the same for me... This are my thoughts...

[Teclast X98 Air 3G] HDtracer:
I have been following this thread from the start and I am lost as to where it is going atm.

Reading through it all, be honest. Before you start messing around dual boot do you really need it or will either Windows or Android be sufficient for you and are you prepared and knowledgeable enough to troubleshoot all the problems?

Before you say you need Windows to do "real work" go buy a laptop if that is the case!

It will be faster, easier to use, better on battery, have a proper amount of storage/usb ports/hdmi........ the list goes on.

I have seen some Acer and HP laptops for sale in shops here for not much more than what I paid for this tablet.

I tune some aftermarket fuel injection computers in cars, would I use a tablet for that, FCUK NO!

With dual boot Android seems so hobbled with such a small amount of memory, why bother with it at all?
