Help recover a lumia 720 if poss please

its been one of those nights !!
My trusty old lumia 720 is on o2 Uk and Cyan became available today
currently the phone was running 8.1 dp but not update 1
as is the way the phone would not dl Cyan as 8.1 dp is blocked from recieving Cyan
tried to downgrade to 8.0 with NSRT but the software would not write to the Rom
reinstalled pc NSRT , ran the software and at 1% write, the process failed !!
NSRT as usual says power and vol down and click ok to recover on Pc
tried everything but the phone is now un responsive, appearing dead
no matter what i cannot get a flicker from it
my guess is the write process over wrote the start of the rom enough to stop a boot
i have had a dable with the NCS software but i am missing the top option ?? which is shown in the walkthrough
can any of you guys throw any light on or IF the phone is recoverable at all ??

It is very simple method dude.
1st install latest NSRT(WP8.1 compatible) with required drivers & tools.
Check your phone driver also Boot Manager driver sometimes it fails. check your .ffu online, download & write.

The Nokia Software Recovery Tool is a funny thing. I've been using it a lot the last few days, and I've had lots of problems. I used it on a 1520. The USB recognizes the phone and when it restarts to install the software the PC doesn't recognize the phone. That happens on ONE of my two USB drives.
When I used it with my 1020, the NSRT didn't even recognize the phone. The PC did because it opened up the WP app automatically but NSRT said "Please Connect Phone" still.
All of these problems were solved by simply using a different PC and that is my advice to you. If that doesn't work, take it into a Microsoft Store.

[Q] Teclast X98 Air 3G: Semi-brick

Hello XDA!
I Pray for Help
I have a tablet: Teclast X98 Air 3G 32GB C9J8.
- It all started with the fact that when you install Windows 10 I formatted all partitions.
- Windows 10 install. Everything worked well, except for the battery. The battery not charging while working in Windows.
- It was decided to return the Android OS. But it was not there. I was not able to install android through Manufacturing Flash Tool, because the partitions have been deleted.
- For a long time I was looking for ways to solve this problem, but the solution I not found.
- Well, to hell with it with android - I said. But the problem is that while I was looking for a solution to this problem - I created another problem:
Now tablet not booting to Windows 10. After turning immediately goes into the BIOS. And when I try to run the install from a flash - nothing happens.
- I tried to boot from a live usb, but no result.
- I think something happened to the EMMC.
- But there are two workable options: EFI SHEll and WinPE5_TechAdmin_UEFI.
- EFI Shell works, but does not allow to load the installation Windows with usb flash by running and bootia32.efi or bootx64.efi.
- WinPE5_TechAdmin_UEFI: Run the menu with different options:
- Installation
-diskpart
- Acronis
- etc.
Windows installation runs but produces different error types: ACPI_Bios_Error or 0xc0000XXX - winload.efi
Acronis starts, but after entering my tpad hangs.
- Who can recommend?

Hello mate . Any changes? Did you fix it ? I got techlast x98 3g 64 gb fully working maybe i can help you with somethig to take my os to upload on a server . Maybe you can fix it . I have no ideea . Just trying to help

Hi everyone.
Any idea or problem solution?

Nothing happened in the meantime ?
I am in more or less the same situation. So I liked to hear what now is yours.

I am in the same situation as you, i cannot boot from any usb device, i also tried booting from the efi shell but of course i had to same problem as you. At least i still have my android 5.0 rooted that works fine but i would like my windows to also work
I have tried a lot of things but am also nearing a wall and was just about to make a similar thread as you.
Edit: My situation is not exactly the same as you as my windows 8.1 is not working instead of win10... When i try booting into windows 8.1 i instead get a blue screen and get to the recovery options for windows 8.1, but none of the options work. Of course i can use the CMD option but chkdsk and similar commands don't help

Have you tried to flash a custom android rom like mireks?

With the windows manufacturing tool you can repartition your tablet. Maybe give it a try

Teclast X98 Air III 32GB Android version - Install Windows 10

Hey guys,
my x98 Air III will arrive in the next couple of days and I plan to run Windows 10 on it. i got the 32GB Android only version and hope since there is a 64GB dual boot version that the bios isn't locked and I can boot from USB. Has anyone tried this already?

http://techtablets.com/2015/09/teclast-x98-air-iii-gets-dual-boot-bios-and-files-released/

i want to give it a try but i'm a bit scared i mess up my shiny new tablet...
i found some more info and it looks like it should be possible to turn my tablet into a dual booting device. The 32GB version that I have is M5C5
http://bbs.teclast.com/thread-518225-1-1.html
i just connected a powerd hub and put teclast win10 on an external usb stick. i interrupted the boot by hitting esc on boot, tried to launch from usb, but it didnt work..

Ordered mine yesterday. My plan is also to put Win10 on it, so I'm collecting info/files on how to do it. Maybe Chris from TechTablets will make a video of the process before mine arrives?

he just released a review: http://techtablets.com/2015/11/teclast-x98-air-iii-review/

I've managed to install the dual boot bios on my Air III, but couldnt figure out why flashing was failing. Every time it would go to 10% and fail (when using that Intel's flash tool).

So how did you make it work? Could you post some instructions?

I was succeeded flashing dual boot bios,
and re flashing android 10G patition .
however, I cant boot windows to install it.
dual booting mod didn see windows logo.
I trid to make a booting USB, winpe USB.
didn work out.

Im at that stage now as well. I couldnt flash the rom automatically so I had to manually input the fastboot commands. Got few things to try in regards of delpoying Windows on it, but that will have to wait until I get home though.
I will put together a guide once I manage to get Windows working, hopefully sooner rather than later

How did you manage to install Windows? Can you provide links to files needed to install it?

I'm pretty happy with Android right now, but I wonder if the UI response is more snappy under W10. I already have a USB prepared with the Teclast W10 version. Just waiting for instructions on how to flash bios etc..

I have done a clean Windows 10 Home 32bit (TH2 1511) install and use the driver package from HERE.
All works fine yet but i know one issue with screen brightness:
When i tap the brightness icon (with 25-100%) there came a point with 0% brightness and i tick it and the screen was off and no chance to find the right button without screen
I restart the tab with 15sec. power button but after the short welcome screen, the screen goes back to dark.
So i must use a keyboard and start the tab in rescue modus and set the power managment to "standard". After this the screen was on after next restart.
My question: is it possible to delete the 0% entry in screen brightness?

How did you manage update BIOS? Did you flash it from Windows PC with USB Debugging enabled or from EFI Shell? My Windows desk cannot find Air III, it says 'no devices found'.

I have managed to put windows on it, by downloading all the files directly from Teclast forums. However, windows is in Chinese and I cant seem to change the language to anything else. Everytime I download a new language, it fails without oving me a reason any suggestions what to do?

arczi:
if you let me know how you flashed the bios and which files you used for the install, i will put it on my tablet as well and we can figure it out together

Thanks, did that and all is fine now. Only trouble was none of the drivers were included in the official ISO files, so I had to manually install a lot of things. The file that can be downloaded directly from teclast is optimized and preconfigured with all the drivers that are needed.

First of all get this: http://pan.baidu.com/s/1kTyAH2f
Secondly, follow this tutorial to install all necessary drivers and tools: http://forum.xda-developers.com/showpost.php?p=62823535&postcount=5
Thirdly, manually edit "Update_Android.bat" file (comes with a package that you have downloaded as the first step) to make sure that all file paths are correct - most importantly the 4th line of this wile, where it points to Intel Manufacturing Flash Tool. Also make sure that there are no Chinese characters in any of the file paths.
Lastly, run "Update_Android.bat" and follow the instructions there I've found that unless you get everything right (all file paths and tool) there isnt much risk of something going wrong, as nothing will actually happen.

thanks for the info! just installing windows 10 on my m5c5 32gb air iii right now, seems to work bios flash was easy and painless. after flashing it took a while for the tablet to power back on. it also didnt see my win10 install usb stick at first. after a few trial and error attempts it eventually booted into windows install.
I'm installing stock windows. which drivers did you use to get the tablet fully working? right now I'm getting the July 2015 Air 3g Windows 10 drivers from techtablets

I have used the same package, majority of drivers can be downloaded using Windows, but there are some missing and thats where the package comes in useful.

Best Rom and Bios for X98 Air III 32GB M5C5 FEB 2016

UPDATE MARCH 2018:
I finally converted my Air III tablet from an Android only into a dual boot Win 10 and Android system. I'm using my laptop a lot in the office these days and didn't feel like schlepping it home every day. My Air III is now my home computer.
I'm surprised that it can run one of my favorite games that just came out: "Into the Breach" with no problem. I connected a Apple BT mouse and it's a cool little portable system for Indie games. Other ones I tested that run well are Shovel Knight, Super Meat Boy, Celeste and FTL. As a gamepad I use an Amazon FireTV controller that I link up through BT.
For those of you who still tinker with this tablet, here are some instructions to get dual boot working:
1. Install Mirek190's v7 rom for Air 3g. Copy the 6GB partition table and also the "boot-air3-m5c5-moded - boot.img" (extra download from mirek) to the ROM folder. For your convenience, here is a ready to flash version for the Air III, already modified with the right boot.img and 6GB partition table: https://mega.nz/#!5xMVgRyC!gHfvg3L3kXzL-NOFfTHvk4_nalKRM-io8DtnGhRCUXU
2. DOWNGRADE YOUR BIOS! - This took me a while to figure out. 2.05 is still the best bios to use for Android only but if you want Win10, downgrade to 1.00. 2.05 Bios does not work for dual booting on Air III.
This is not without risk, but I confirm that the following link to the 1.00 bios worked for me: https://mega.nz/#!VgMWVZjZ!SgSzryJkn89RWMidg_Um8Ab1wgDnZ8JWGwgK-yR2dj8
Unzip the contents of the folder to c:\update_android - If you have Mirek190 v7 installed it will have Supersu and USB debugging already enabled for you. Execute c:\update_android\android\Update_Android.bat with the tablet booted to Android. Note that there is two Update_Android.bat files. Makes sure to use the one in c:\update_android\android\
3. After the successful flash, connect a powered usb hub to the tablet via OTG cable. Connect a keyboard and USB stick to the hub. Follow instructions from Techtablets: https://www.youtube.com/watch?v=rLjayeQJg4Q
In order for a successful Windows 10 install you need Rufus and a 32bit copy of Windows 10. I used en_windows_10_enterprise_x86_dvd_6851156.iso. Create the USB key with Rufus and make sure to choose GPT partitioning.
4. After everything is set up, install drivers for Win10 Air 3G from Techtablets
5. Android should have around 5GB of space and Windows will end up with 15GB of free space. It's good practice to install software to an external SD. Especially WIn10 can run out of space quickly with all the updates it loves doing.
Hope this helps someone

ORIGINAL POST FEB 2016
Hey guys,
I just installed the following bios and rom to my Air III M5C5. I switched back from Windows because Windows was somehow buggy and didn't have much to offer for tablets:
I followed Kuba's advice ( http://techtablets.com/forum/topic/best-rom-for-x98-iii-m5c5/#post-25075 ) about best rom and bios for M5C5:
DOWNLOAD ROM https://mega.nz/#!8s92TbCR!w-vVyqbnqVf3p3YJP_obj2xRm_7f7sx9YMqVhLm4hXA
DOWNLOAD BIOS http://forum.xda-developers.com/showpost.php?p=65166671&postcount=87 (thanks to skubidoo)
You will also need Mirek's ROM: http://techtablets.com/wpfb-file/x98_air_2_android_5-0_mirek190_v5-0-ultra-light-7z/
I can confirm my X98 works better than ever! Both cameras are working and the device feels snappier than the original Teclast Android rom that came with my device. The rom is the official Teclast X98 Air III rom for recently shipped devices. Thanks to guvno for making this available to everybody! I first thought I will install the debloated Google Now rom for the air iii but since this is based on the original Teclast rom that I used to run, it wouldn't have been an improvement in terms of speed.
Here's how to install the ROM
PREFERRED METHOD TO GET THE RIGHT BATTERY DISPLAY:
- Prepare guznos rom for MFT:
Go to folder "X98_Air_2_android_5.0_mirek190_v7.0-ultra-light" - "ROM-backup"
Copy and replace droidboot.img, efilinux-userdebug.efi, flash-full_with_REPARTITION.xml and installer.cmd to the guzno folder.
- Install MFT software following tecknight's tutorial (http://forum.xda-developers.com/showpost.php?p=62823546&postcount=6)
- Now start MFT and select "flash-full_with_REPARTITION.xml" from the guzno folder.
ALTERNATIVE METHOD:
- Install the drivers IntelAndroidDrvSetup1.10.0.exe and IntelDnXUSBDriverSetup.exe in Win7 from "X98+Air+III(M5C5)+-+guvno"
- I put my device in DNX mode (holding down vol up, vol down and power when tablet is switched off)
- Used the batch file "flash_rom.bat" from "X98+Air+III(M5C5)+-+guvno" which then installed a freshly rooted rom of android.
Here's how to install the BIOS
I downloaded X98_Air_2_android_5.0_mirek190_v7.0-ultra-light, replaced /data/BIOS/2-05.bin with the one from the above mentioned link (https://mega.nz/#!dYxVTQrL!J9h-bk-hWzE80UK2MSzRd2CBiAoYY8TF6XXr-JwpgdU). Then I launched FLASH_tool_Teclast_x98_air_devices-v3.0, hit 4, then hit 2 and select 2.05. IMPORTANT Make sure you select only this version and make sure you replaced the right file. Be very careful with this step because if you accidentally flash the bios from the Air II to your Air III, it can brick your device!
For me, it worked correctly and updated my M5C5 to the most recent BIOS. You can tell because the tablet doesnt start up displaying chinese letters anymore but instead showing the latin letters TECLAST
If you want to keep your Windows installation I believe you have to change partition.tbl but not sure how this would work. I'm Android only now.

please can you post a screenshot of the device versions (Android Version, Kernel-, Build-Number, etc.)?
Thanks,

Android 5.0, build number is V1.00_20151204, kernel version 3.10.2 (December 7th 2015 10:50:43 CST).
This version is already with root

This rom works really great but the notification bar is flickering in some apps, someone has the same problem?

Yes, I'm returning to Sikke1's Rom because the flicker annoys me
I tried mixing Clean Rom+System.img from Sikke1's Rom and is working very good, but unfortunately the rear camera is upside down.

I haven't noticed any flicker yet...which apps are you guys talking about?

Try to disable gravitybox if you are using it. That helped for me on the flickering issue on mirek's v7.0 rom

So is this new stock rom worth switching? what about ui fluididy and battery calibration problems? has anyone tested it, who really does know the problems of the other available roms?
greetings

There isn't gravitybox into that ROM as mirek's, so thank you for your reply, if i found how to solve it, i will write here

Right, there is no gravitybox in stock ROM.
The battery status is fine for me, the only thing which is not 100% OK for me (beside this flickering) is the touch screen sensitivity.
Some times a have to touch twice for reaction - is this normal for this screen?

battery is reporting the correct values and i don't seem to have the flickering problem. i'm very happy with my Air III now, it's a big improvement in UI responsiveness to the original one. i didn't notice any problems with sensitivity...

Glad this ROM was usefull to more than just myself. Thanks to ionioni and hordarian for the adb commands on dumping and packaging the dump files to a flash package.
I myself was using custom ROMs until one of my units came with a clean AOSP ROM which this is. Finally Teclast has started to supply their customers with this instead of their bloated versions. All manufacturers should do this IMO. Release their own customized version to the general public but give the tekkies a clean AOSP version to play with ☺

For me the best rom is android 4.4 mirek version or other.
With android 5.0 battery drain so fast, just try android 4.4
My bios is dualboot V1.00. (m5c5)

i noticed the flickering notification bar today in google photos and tapatalk when scrolling. clearing notifications seemed to get rid of the problem. considering all the problems i had with tablet in the past ( battery drainage, random freezes, screen unresponsive, slow scrolling, lagging, constant driver installations and updates in win10) this wont bug me much.

Just to complete the picture:
The BIOS Version is:
Project Verion: tPAD 2.05

Right?

You can fix the flicker by checking "disable hw overlays" in developer options. It doest seem to have major disadvantages turning this on from what I gathered...you basically force the use of the GPU for screen compositing which might free up the CPU but might have some unwanted side effects like obstructed image rendering. I think you have to turn it back on after restart or use a script like this one http://forum.xda-developers.com/nexus-4/help/disable-hw-overlays-force-gpu-rendering-t2227089/page2

Can I flash this rom over sikke1's debloated rom without any issue? Because sikke1 rom has 100MB cache partition and 1GB data size. Does this matter?

If you use the flash ROM batch file with the standard partition table it will completely reset your tablet. So no, it shouldn't matter. I had windows installed and it just repartitioned the tablet.

Has ANYBODY been able to dualboot a M5C5 Air III?

Hey everybody,
I do own a X98 Air III (M5C5) and after long hours of reading on xda I am wondering if there is a single documented case of succesful installation of a dualbooting system on the M5C5 model. Most seem to fail at flashing Mireks ROM in the first place. The lack of clear, concise instructions looks to me as if there is no safe way of flashing this particular model right now. Does this sound right to you or is there something I overlooked?
Thanks a lot!

I have successfully installed the dual boot v1.00 after a softbrick trying to install the 2.02 bios. I think the issue is that your tablet is not rooted, that is why you cant flash android. Look @ the ionioni tool to unbrick soft-bricked tabs on how to flash that dualboot bios. Keep reading you will get there

Well, you flashed the BIOS and - as I was stating - first of all softbricked your device, due to lack of proper instructions. There is absolutely no comprehensible information on how to correctly flash or modify this model of the X98 Air III on these forums right now.
Also: did you simply install the 1.00 dualbooting BIOS or did you succesfully install both Andriod AND Windows at the same time? I guess flashing the BIOS can be achieved but again: theres no information on how to properly install Windows & Android on the M5C5. Anf if there's people like you out there who've done it, I don't understand why nobody bothered to document their process and share it with everyone..
Thanks!

Installing Windows and Android is the easy part, once you get the dual bios working. Look at this page (http://forum.xda-developers.com/x98-air/help/unbrick-bios-softbrick-withouth-eeprom-t3285054) to find the files and how to flash them. The only duil bios avaliable is that v1.00. When you successfully flashed that you can install android in dnx mode with partiotion tables with less than full partition size (I personally used the 3gb partiotion, you can find it in mirek190 roms) and than you just attach a otg hub with a bootable flash drive with windows 10 32 bit(never go for 64bit - you will brick), boot in bios by holding Esc on your keyboard (that you also have connected to the hub, as well as a mouse btw), than select the boot drive (you can find a tutorial @ Techtablets youtube page).
I have swapped between the v1.00 dual boot bios and the 2.05 android only bios a few times, and it works fine. Read all the posts in the page above to better understand how dual boot works.
Good luck!

Hi, thanks for detailing things a bit. :good: Is there any major disadvantage to using the dualbooting 1.00 BIOS as opposed to 2.5? Missing features? Other relates quirks with the 1.00 BIOS? I was wondering since you swapped back and forth with both versions.
Thanks!

Hi, there a few problems with the 1.00 dual boot bios and I think its because it wasn't meant to be used with the M5C5, our version of Air III is supposed to be Android only and we are basically hijacking the bios from c6j8, that works but its not perfect (at least for me). The main issues I have encountered is not really with any of the device capabilities - the cameras, wifi, hdmi and everything else works as good as it was intended but sometimes I run in to troubles when switching on the device. When I let the battery run out I will not be able to turn the devise on until it is charged up to 40% (that takes around 45 min) that can lead up to a few minor heart attacks the first couple of times you encounter that. The way I deal with that issue is by never letting the battery run lower than 20% so its not a problem for me but if you use your tablets in such a way that they run out of juice constantly I would suggest you just stick with the android only bios - the one you currently have or the 2.05 version (you might already have that on your device).
Now the advantages of dual boot are many - I believe Windows is a superior OS, in the way that it gives me a lot more productivity and multitasking capabilities that I personalty enjoy. For some reason the volume goes a lot louder on Windows than on any Android rom I have tried. I do believe we should get the most out of our devices and that's why I stick with dual boot for now. It is far form a perfect solution but everyone that reads this should evaluate the pros and cons - if you don't mind the stress of not being able to turn on your devise for 45 min or so you might enjoy the dual boot (or might be able to find a better dual boot bios).
As a conclusion experiences with Chinese tablets always vary from one to the other and it might be just my unit that is faulty (the boot up issue) so all you do is at your own risk, but if you keep on reading and trying out solutions you can get a lot of stuff working (just remember to breath)

Well that was very helpful. I might consider simply replacing stock android with mirek190 v7.0 at this point. It seems having Windows 10 available is not worth the hassle for me, when it comes to the bootup issues you described. Thanks for clearing things up significantly for me! :laugh:

Is there any proper dualboot bios other than v 1.00 for M5C5?

Hi folks,
I ordered a Air III a week ago and I haven't got my hands on it yet. But from what I found researching the forums is that there's a version of 2.05 bios that's been reported working with the Air III. Refering to the following 2 posts:
http://forum.xda-developers.com/x98...m-bios-x98-air-iii-32gb-t3310436#post65204355
Then I downloaded X98_Air_2_android_5.0_mirek190_v7.0-ultra-light, replaced /data/BIOS/2-05.bin with the one from the above mentioned link (https://mega.nz/#!dYxVTQrL!J9h-bk-hW...8TF6XXr-JwpgdU). Then I launched FLASH_tool_Teclast_x98_air_devices-v3.0, hit 4, then hit 2 and select 2.05. It updated the M5C5 to the most recent BIOS. You can tell because the tablet doesnt start up displaying chinese letters anymore but instead showing the latin letters TECLAST
If you want to keep your Windows installation I believe you have to change partition.tbl but not sure how this would work . I'm Android only now.

DONE!
It's true the first boot logo is about BIOS. I made backup and flash it by mirek tool
Here you can find it: https://mega.nz/#!dYxVTQrL!J9h-bk-hW...8TF6XXr-JwpgdU
Just replace this file in \X98_Air_2_android_5.0_mirek190_v7.0\data\BIOS and run flash version 2.05

The only I'm not sure is if I have to (or can) flash Mirek rom using MFT BEFORE flashing the bios so it's pre-rooted.
Can anybody confirm this (@mrchrister ?) and also if you need the tablet to be rooted?
Thanks
