Running HARD-SPL/Flashing ROMs without Windows? - XPERIA X1 ROM Development

Hi,
Just got an Xperia, and I'd like to follow the tutorials on flashing the WM6.5 OS onto it.
My problem initially is that all my PCs run Mandriva Linux, not Windows, which means that the .exe files etc provided won't run on my machine.
Is there a solution for this problem? Obviously I have no ActiveSync etc and although I can still connect the phone via USB, I'm a little nervous about trying to work out how to do this off the cuff - don't want to end up with a brick after all!
Cheers
Dave

If you have just got it, then start searching and reading first !!!
sticky threads have the most information you need.
anyway, quick response, hardspl with no windows i don't think so, but rom flashes yes you can with the microsd method.... you'll find info everywhere....

I recommend you to use a xp boot cd or other windows boot cd that can mount the OS in your pc or to make a partition with windows...
Because to do a hard-spl you WILL NEED WINDOWS....Activsync from microsoft...Shuold by active and running conected to your xperia of course...
For roms flashing you can use MicroSd method so not problem with your pc OS...
READ and Study a lot after doing....ANYTHING
Wish you Luck

Thanks guys.
I had already seen and read through the points on using Micro SD cards for the ROMs, but hadn't been able to locate anything on doing the Hard SPL any way without using Windows. Thanks for clarifying what I thought was the likely answer.
Looks like I'll be spending my lunch hour productively at work next week...

the easiest way for you will propably be :
1. Go get Virtualbox (free!) or VMWare Workstation/Server
2. Setup a new virtual machine.
3. Install Windows XP in this machine.
4. Install virtualbox guest additions in virtual machine.
5. Install Activesync
6. Connect your X1 to the usb while virtual machine is on focus.
7. Put Hard SPL on that sucker.
That's how I did it and have done it for some friends.
Alternatively just do it on one of your buddie's pc who has got Win.
It takes only few minutes.

Easiest way ever to install win7 on shift

I had many difficulties to install windows 7 to my shift, maybe because of my USB stick. And then every guide was a little bit complicated - too many instructions, too many steps, too easy to make a mistake and then go back to the beginning..
Didn't want to buy an external dvd-drive either..
Anyway, all this before I found this article.
Check this out
Installing Windows 7 without using a DVD or USB via direct method - No USB stick required. No USB drive required
In this method we install Windows 7 on a clean partition like the normal DVD boot method. Only change is we don’t use a DVD drive in this guide. Please follow the below instructions carefully and don’t skip any steps to make things quickly!
1. Download the Windows 7 ISO files from Microsoft. I hope you have already downloaded one.
2. Download and install Virtual Clone Drive from http://www.slysoft.com/en/download.html
3. Firstly, go to the directory where you have saved Windows 7 ISO file. Right-click on the ISO file, select Open with and then select “Mount files with Virtual Clone Drive” to mount your ISO file.
4. Go back to My Computer (or Just Computer) and then double-click on the Virtual Clone Drive icon to start Windows 7 installation process.
Yes, you are installing Windows 7 without a DVD or USB drive!
5. Next, follow the normal Windows 7 installation procedure to finish the installation. Windows may restart during the install process. Worry not, everything will go fine.

ok, now the short way to make a bootable USB Disk to install Vista/7
cmd
diskpart
list disk
select disk $ [where $ is the number of the USB Disk listed in the list disk command]
clean
create partition primary
select partition 1
active
format fs=ntfs quick label="InstallUSB"
assign
exit
exit
Copy the content of your Installation Disk on USB and boot from it, just simple as that
do this method install the new windwos over the existing windows, or on a new partition in HDD.
As far as I know, no version of windows allows installing of a new windows except from booting.

I just tried it out and it installs it over the existing running windows, doesn´t matter if it was downgraded to xp, or already upgraded to 7, it will install a new and fresh copy of Win 7 in your local drive, regardless of the existing vista recovery partion, which can be used in any time... (I hope to get ride of it once Win 7 final version comes out...)
When the installation is complete, a folder called "old windows" saves all the files from the preivous running operating system, bt since it´s over 10 GB, I suggest you erase it..
Win 7 is fantastic!! I have my shift now running both Internet Explorer 8 and Opera, Office Pro 2007, Skype, Live Messenger, Eset Smart Security 4, Adobe Reader, and more.... as smooth as butter
Great..............Shift on W7.
Please someone could tell me if the differences are big using W7 instead Vista.
So, it's a great solution to move Shift to run on W7, or not ?
I upgraded my hard drive then changed to windows 7 with a clean install. It is amazing how much better my shift runs now that it is on W7. It is really worth it to upgrade.

Windows mobile 7?

flash tells me it isn't a BA, when I know it is

I have definitely got the blue angel. It is an O2 Xda 11s.
I have downloaded the how to flash your BA pdf by D-Two, and followed the instructions. It gets through to the stage where it's about load the software onto the phone, and then it quits saying that he phone is not the appropriate model.
device information
Operator version: PDAViet.net
ROM version: 6.01.10 VH
ROM date: 07/08/08
Radio version: 1.06.00
ExtROM: diamond (01)
RAM size: 128 MB
Flashing eyes: 32 MB
Storage size: 60.3 MB
At present I have windows mobile 6.1.
And suggestions please?
for upgrading, you use the MAupgradeut_noID.
that program avoids country id errors but it was originally made for the magician, hence MA, whereas the original BA upgrade utility is called BAupgradeut.
that is why you get that error. you have to put the device into bootloader mode before connecting it to the pc and before starting maupgradeut_noid, that way, you avoid the device id check.
make sure to follow the correct upgrade procedure, found here: http://forum.xda-developers.com/showthread.php?t=630416
These are the instructions I used;
Temporarily remove your SD Card (it may work for you with the SD card still in your BA, but you may not be able to enter USB mode when cradled).
Put your device into Bootloader mode by pressing and holding the "Power" & "Record" buttons, and then press the Reset Button. Help me with this step
Connect the phone to the sync cable/cradle. sarcasm ahead Note: Did you see a sign out in front of this point that said: "You can flash using BlueTooth connection?" You know why you didn't see that sign? Because you can NOT FLASH using BlueTooth!
Now you can execute the installer file. (something like "MaUpgradeUt_noID")<--------------- Used This
Here is the screen just before boarding the software.
http://i627.photobucket.com/albums/tt356/Pterodactyl_2012/ba1.png
And here is the error message.
http://i627.photobucket.com/albums/tt356/Pterodactyl_2012/ba2.png
nope, you are not using the proper maupgradeut_noid, because that would show a magician on the left, whereas your pictures clearly show a BA, so download the Chef_Tony RUU from my signature and try that. it has the right maupgradeut_noid, that will avoid errors like that.

you are trying to flash using vista/7 have you read d-two's manual about that, with the customized driver and everything?
alternatively try a windows xp pc and follow the tutorial in my signature (the read first link)
and make sure, that you don't copy around the rom too much. download the rom and the ruu directly to the pc you flash from and use it from that folder directly. i use windows 7 on my main pc and can only flash from my netbook which runs windows xp, and due to too much copying, i had similar errors, because after copying the rom to a usb flash drive without problems, still the crc changed.
don't worry, your case is far from hopeless, but you seem to be unlucky and go through every problem there is

Okay yes, I should have said this. I am using windows seven on a Lenovo N500 4233 32g. The problem is, trying to get hold of an XP machine. Have you tried running this programme in compatibility mode? I will have a look at your instructions and see where I get to.
Thanks for your help,
Is d-two's manual, the HTC service manual in you sig?
no, it is to be found here: http://forum.xda-developers.com/showpost.php?p=5456317&postcount=6
compatibility has nothing to do with it, neither has the xp mode or any virtual machine, because there must be suitable windows 7 drivers present. but i cannot help you with his tutorial, since i use windows xp for flashing and have never successfully used windows 7 for flashing.
the htc service manual in my sig is the official htc manual for hardware repairs, you can learn to disassemble the device there and have a list of spare parts

What's Wrong With My Computer!?!?!

I have two PC's, one is a XP Media Center Edition. It had a virus on it and kept getting a corrupt file, so my techyish relative came and wiped the hard drive from scratch ( or so he says but it was a partial wipe) and reloaded the OS onto it. It worked fine, but then kept getting the corrupt file again. I then decided to order the recovery disks from HP, which is the computer manufactuer. They arrived and I put them in, followed the steps, and all wen well until I came to the recovery partition. It was backing everything up ( one time process only) into the recovery partition all fine and dandy until it came to a file that had to do with Microsoft Office. It stayed their for about 45 minutes backing up this file where the longest had been 10 minutes max for all the others. I looked the file up and it said it was a small 10 mb file, so I turned the computer off and went to normal without the recovery partition. Worked fine until one day something happened and I guess I needed to do the recovery again (it's been a few months since this has happened) and did all the steps, but it wouldn't take. It gets to about 4% and then dies with a BSOD and this message:
A problem has been detected and Windows has been shut down to prevent damage to your computer.
DATA_KERNAL_INPAGE_ERROR
If this is the first time you’ve seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.
Technical information:

Copied it down word for word, space for space. Can anyone help me get this thing up and running again? It's now getting important.
Forgot to mention that I get the same problem each time I put the recovery disk in.
I'd recommend using a NON-Recovery Disk, but rather a Clean, Non-OEM, Windows Disk. If the issue pertains to the Kernal, it's usually unfixable without a Hard Boot of the Drive. You should do more than Re-Format.. you should delete all the partitions off of your Hard Drive with a Windows Disk, then pop in the Recovery Disks and do the OEM install.
So I need to wipe the hard drive clean again and put in another non OEM OS?
Not quite. Wipe the HDD clean with the NON-OEM Windows Disk, as most Recovery Disks do not allow you to alter the Partitions [Everything is done for you], then pop in your Recovery Disk and let it install the new Primary, and possibly the Recovery, Drives.
I see what your saying now, so what exactly happened to it?
Get Windows 7
I have windows 7, that's my other computer.
The guy at the un paso store got you too!!
At the step store? Lol.

When your supposed "Tech Savvy" friend attempted to fix your computer.. he, I'm assuming, did a simple "Repair" of the partition with an XP Disc. That is LITERALLY the most unwanted version of a fix ever... All it does is replace the system files, but keeps all of the other software that may have been conflicting with the system itself, BUT usually, all of the software is inaccessible. It's still on your computer, f*cking it up, but you can't see it.
Thus I always say, "If you get a bluescreen... more than once, and don't know what the code means... don't repair your computer.. re-format that b*tch after recreating the partitions."
But, if your XP compy has the specs to support Windows 7, your best bet, all in all, would be to install Windows 7. Doing so will save you the hassle of having to manually download all of the drivers for it... unlike installing a non OEM Windows XP [have to download & install the drivers manually].
PurpleLlamaLover
it sounds like the HP recovery disk could well be corrupt,
So you now have 3 options:
1. Try Linux Ubunut 10.4 LTS (Free Distro)
2. Buy a ligit copy of Windows 7
3. Download Windows Vista / 7 / XP from a torrent
and try untill you find a OS you lyk

I'll try and get 7 for it. It was the last of the XP models, just before vista so i'd think it should be able to run 7. Think I need a new hard drive?

Really? Well, i'll keep in mind if I can't get XP back on it. I'd rather just have 7 and XP. I don't care what it runs as long as it runs again.
the best suggestion in this thread was install linux , however i take it that isn't a possibility. so here's what you need to do, you will require the following:
1) a fresh mind
2) a freshly burned copy of XPwhateverflavoryouwant
3) you do not care about anything on that drive.
put in freshly burned xp into computer, boot to cd drive, follow onscreen instructions, delete all partitions, create new NTFS partition, install to new partition.
if error comes back, it is not a software issue. fixing a xp bsod really is simple if it isnt hardware related.

But I can't get this step:
reset your device and within 3 seconds push together the Vol_Down + Back button (the one on the right above the hangup button) and keep pressed until the boot loader appears (the one with the color stripes)
I have a broken button..
so you have to use mtty, but you need anyway a windows based PC (as I know) to install crude usb drivers...
Ok, Thanks for your help
I use VirtualBox on Arch Linux with Windows XP... I can't flash directly on the cell as ActiveSync doesn't recognize the device, but maybe MTTY, with different drivers, works
I use virtual machine with windows xp,, to use mtty on my windows 7 based pc.
All you need is an virtual machine,,

Teclast x98 Air II

Hello
I bought a Teclast X98 Air II . It says it comes with android installed. Does anyone knows any way to install windows 8.1 on it?
I managed to obtain win8.1 from the teclast forum, the firmware for this specific Air II.
But there was nothing mentioned regarding the bios part. Any ideea?
I will upload 8.1 firmware soon on some share.
Any help? Anyone else with an Air II?
Thanks
Subscribed to this topic as I will also receive my air II very soon and want to install Windows onto it.
via tapatalk
done
good news:
1. received my teclast x98 air II
2. managed to install and fully run windows 8.1 bing edition.
will post in the short future a full tutorial that will include rooting, installing, activation
will also provide every software / files needed.
does anyone recommend any file sharing service?
Try firedrive.com - as far as i remember you get 50gb for fairly fast storage.
And most of all - thanks for your help, it would be great if you could write a tutorial here.
via tapatalk
Subscribed too, I'm also very interested in how you managed to install windows. I ordered my x98 air 2 a couple of days ago. I will be going to install windows as soon as I get it.
bios brick
can someone send me a right bios for the teclast x98 air 2? i only find x98 air or x98 3g.
i want the bios for android or for windows or both, i take all i can get.
now my tablet cant startup, without a bios. i need a new for external flash.
sorry for my bad english, im from germany, i hope u can understand me
edit:
if i get the bios data i can install any other windows not only the bing version. but with the brick i cant do anything, and i cant find any bios for windows and cant find for android...
i get the hardware driver from another(german) side for display and so on, i just only need the bios data ...
Thanks. I'll be watching this thread as well.
I am seeing conflicting information on whether this tablet has GPS capabilities or not. I would love to have someone confirm what it actually has. If this doesn't have GPS then I'd be curious to know if there are any alternatives.
I am too new to the forum to post links but you can search on YouTube for videos from user HONGKONGEEK where they have posted an Unboxing video for this version of the tablet.
that's awesome, mkdk!!
Instead of the Win8.1 Bing version, is there any chance of flashing a Pro version instead?
I bought this tablet with the high resolution with the intention of installing Win 8.1 so I don't have a pay a premium price for a nicer screen.
Can't wait until instructions are released!
This will be my first post of many .
Awesome work mkdk, did you follow instructions for the first air or the 3g version?
Bought the 3g version for my girlfriend and the android version works well for her. No luck for me with my air II since google play wont work, so now im looking to install windows instead .
Looking forward to the guide!

AFAIK you can install Pro if you integrate the Teclast drivers into the image (use Wintoolkit & Rufus).

So how do you go about his, are the instructions from teclast x98 air 3g also valid for the air 2 when it comes to flashing the bios?
FIY i did the latest OTA from teclast on android and google play/services still does not seem to work so i guess android is a big nono, atleast for now.

best man! you made my day! thanks!
*** I would count these instructions as obsolete due to some gripes with drivers, please refer to JonMichaels instructions in a later post. I will however leave this post if someone needs it as reference or has problems with the other method ***
Ok, so i managed to install both windows 10 32-bit and windows 8.1 pro N 32-bit!
I would not recommend windows 10 since i had a couple of issues there, but win 8.1 works very well with some small gripes that we might solve together!
First a small guide .
Guide to install windows 8.1
For the most part i could use the instructions in the thread for teclast x98 air 3G. I did however not use Teclasts bing version of windows, i created a win 8.1 pro iso instead and embedded the drivers.
Step 1: prepare the image
I only used one usb-drive for my installation (not the WINPE way as described here ), at first i tried with a 32gb drive but it did not work, a 8gb kingston memory did however work. So you might have to test a couple of drives to get it to work. Checkout this post to grab Wintoolkit and Rufus, you will use wintoolkit to inject drivers and refus to prepare a bootable drive.
Once you have these tools you will need to find a windows 8.1 pro 32-bit image to use, i took mine from dreamspark (for students), but you should be able to get one from microsoft directly. Do however mind that i could not bypass the "insert key stage" for a trial version, i had to get a key for this. If you want a fully working win 8.1 pro you will need a key when you install the OS (I don´t know where they are the cheapest, perhaps G2A).
Download the drivers for Teclast x98 air 3G and extract them to a folder. Start up wintoolkit and press all-in-one-integrator to start the embedding process. Browse and select the image that you downloaded earlier. Select the drivers tab and press the Add selection in the menu bar, select the folder with the teclast x98 air 3g drivers, then press start and select a place for the modified image to be storded. Once this is completed (takes some time) close the all-in-one-integrator and select ISO maker, select a place to create a new iso and name it something like "win8.1".
Insert the drive you want to use as a boot-device for your newly created image. Go ahead and start up Rufus and select the drive you want to use. Under partition schema make sure that the GPT partition schema is selected, also make sure that you format it in FAT32. Press the little CD symbol and select the image that you created earlier and press start (this will also take a while depending on the drives writing capabilites). If all goes well you will now have a bootabel usb-drive with win 8.1 pro that the tablet will accept.
Step 2: Flash the bios with the one given to us by nandika6
The next step is to flash the bios to the version that nandika6 gave us. Follow the instructions in this post and use the commands for "if you have not rooted your device".
I had some gotchas with this, simply downloading the adb driver did not work as i could not detect the device in the command prompt. This was solved when i ran the intel manufacturing tools and got the correct usb drivers for the tablet. I did however not do anything with these tools ( look into this if you dont want to keep windows forever, said something about that, i will however not switch back to the buggy Android).
Step 2: Install windows
Once the flash is complete you will have to shut down the tablet and insert the boot-drive. If you end up in the EFI-Shell this will probably be due to the usb-drive not being compatable (this happend to me), in that case repeat step one with another drive. It could also be because the drive is not first in the boot priority, connect a keyboard and pres ESC when booting to get to bios, select the drive and reboot.
If all goes well you will only need to connect a usb-drive since the drivers for touch will work on the fly, if not you will need a mouse and keyboard. The drivers can be manually installed via the device manager (alot of warnings here if this is the case, solve them all by inserting a usb-drive with the drivers folder from earlier).
When this is done you will hopefully have a working istallation of windows on the tablet!
Some gripes
Screen rotation does not work for me at the moment. I solved this in windwos 10 with a file that comes with the drives, this did however make the tablet rotate the wrong way. I will look into this and post a solution if i can, please feel free to inform us if you find a solution first .
The camera is not working for me right now, will look into this.
The tablet will automatically adjust screen brightness even if you turn this of in the power management. This is caused by the intel driver that overrides this, open the intel controll panel and disable active dimming here to solve the issue.
@Thundermeister: helpful guide. Maybe your gripes can be fixed using an updated driver (from the Air II Windows image).
Did you by any chance look into making a WIMBoot image instead of a normal install?

Thanks for the tips mtr33, will take a look at that image (if i can find it ). A WIMboot looks very nice, the space saving would be real nice to have. Right now the install takes up around 8 gb on the tablet. I also found some Onda users having the same problem with the rotation, gonna take a look at that image as well, the tablets seem to use the same sensor for orientation.
For all of you having problems with Google Play store, I have a fix here : http://forum.xda-developers.com/showthread.php?p=56779242
This works on both 4.4.2 and 4.4.4 ROMs.

How to install Windows 8.1 on a Teclast X98 Air II Android Tablet:
You will need:
2 USB Memory sticks - 1 small (no more than 8 GB) & 1 large (6 GB or more)
1 USB Hub (preferably USB2 & powered)
1. Go to this web address 1drv.ms/1EQ1X5v (Microsoft Onedrive) & Download all the files to your computer.
2. Plug the small memory stick into your computer & format it (Right Click on the drive's icon then scroll down & Click on Format) using FAT32 File System & set the Volume Label to WINPE (all caps).
3. Decompress WinPE_User_20140814.rar to your computer & copy the files to the root directory of the memory stick. Eject & remove the stick.
4. Plug the larger USB memory stick into your computer & format it using NTFS File System.
5. Decompress X98_Air_II_Windows_20141022.part1.rar to your computer & copy to the root of the 2nd memory stick. Eject & remove it from your computer.
5. On your Android tablet, go to Settings, Developer Options, & check USB Debugging (then Ok).
6. Decompress X98-Air II-WIN8 bios.rar to your computer.
7. Connect one end of the USB data cable to your computer & the other end to your tablet (close all running programs on your computer & make sure the tablet has at least a 50% charge).
8. Open the X98-Air II-WIN8 bios folder & Right Click on X98-Air II-WIN8 bios.bat & Click on Run As Administrator (enter password if prompted).
9. Type 1 & press enter to install the USB driver (Install driver dialog box should pop up, click Next to finish the installation).
10. Type 2 & press enter to Root the tablet (wait for it to finish).
11. Type 4 & press enter to flash the tablet's BIOS (do NOT disturb tablet or do anything on your computer while it is flashing!)
12. If there are no error messages, press the tablet's power key for 10 seconds to turn it off & pull out the data cable.
13. Plug both USB memory sticks into the USB Hub (& plug it in to the wall, if powered) then plug the Hub into the USB adapter (that came with the tablet). Plug the other end of the adapter into the tablet's micro-USB port.
14. Turn on your tablet & leave it alone until it is done installing windows (should take several minutes).
15. Hold the power button for 10 seconds to turn it off, then turn it back on.
16. After Windows 8.1 loads, change it to your desired language (it will be in Chinese) & enjoy!
