Nvflash-ICS Restore!
This guide will not provide information to install Nvflash-ICS as that is covered well elsewhere.
Once you have read the information on that page click Guide.
All necessary partitions are backed up with Nvflash and you can restore only the ones necessary to recover your unit.
The second method to restore has been removed until further study can be done!
If your problem can't corrected using this information and normal use of recovery, adb, and fastboot go to this post to access the IRC channel for all Asus transformers using nvflash.
I have finished installing Nvflash but where are my files?

Nvflash recovery and going back to ICS for a fresh start.
Use blobunpack to unpack a stock ICS blob. The blob is found by unzipping the stock ICS firmware twice.
You can find the ICS firmware at this link (9.4.3.30) (post #3).

Please give philos64 a thanks while there, without him you would have a very hard time finding these downloads if at all.
these files have to be in the folder with Nvflash
wheelie -r --blob blob.bin -created with Nvflash install
nvflash --resume --download 4 blob.EBT -created with blobunpack
nvflash --resume --download 10 blob.APP – created with blobunpack
nvflash --resume --download 6 blob.LNX – created with blobunpack
nvflash --resume --download 5 recovery.img-ICS twrp recovery image name
nvflash --resume --go
then press volume down to enter twrp, flash root, flash rom or whatever you wish

see post #7 for info - http://forum.xda-developers.com/show....php?t=1068548
There were no dates for the following information.
The current AndroidRoot.mobi bootloader versions are
Transformer Prime: 9.4.2.28r01
Transformer TF300: 9.4.3.30r01
Transformer TF700:9.4.5.30r01
ChangeLog:-
Patch: Enable ‘fastboot boot’ command (removes ‘fastboot continue’, use ‘fastboot reboot’ instead).
Patch: Force unlocked state (protect your unlock status no matter what happens to your token).
Patch: Remove blob requirement from ‘fastboot flash’ (Flash the raw images (example: ICS_recovery.img) and not blob files).

When failing to get into APX mode you can try the following suggestions.
Special thanks to wha2do and daws for their input!
Also wha2do has posted a guide to enter APX that provides detail not found here! Please see his guide and give proper thanks if you find it helpful!
http://forum.xda-developers.com/show...3#post36159253
1.To enter APX mode you either have to boot, choose reboot (if available) and hold volume up pressed until it reboots and then the screen should remain black. Or if that doesn't work, completely shutdown your tablet and wait a second or two and then hold volume up pressed while pressing power on and keep it pressed until screen is blank.
or
2.fastboot -i 0x0B05 reboot (hold volume up)
or
3. adb reboot (hold volume up)
or
4. with unit powered on hold volume up and press reset with paperclip - (don't press hard)
reset is located about 25mm or 1in below the sdcard
or
5. su
reboot -hold volume up.
This is done using a terminal; Android terminal is free from the play store. You must be rooted for this to work.
or
6. Another way:- Provided by daws
Power off the tablet and don't touch the power button again.
Connect USB cable to tablet but not to PC yet.
Press volume up and then connect USB cable to PC.
Wait a few seconds before releasing volume up button.You should now be in APX mode.
Thanks for the help daws.
or
Only if there is no other resort!
7. remove cover from unit, disconnect battery, press and hold volume up, reconnect battery!

Due to my dock smoking my motherboard I have purchased a new motherboard and luckily it came as 4.0.3 ICS.
I now have installed and use Nvflash on my tablet.
In case anyone is interested this is the unit I purchased.
The box shows - Manufacturer's Reconditioned Parts - 90 Day Limited Warranty.

See the original thread for details:
[DEV][TOOL][BRICKPROOF]TF300 NVFlash release!
There's something I've not been quite clear about with NVFlash.
So I do my backup and keep my files.
Afterwards I upgrade to Jelly Bean (because I need the JB bootloader for ROM's right?), put TWRP recovery on, and flash a new ROM that uses the bootloader version I have.
So now I have the JB bootloader, can I still enter APX mode and do a restore, or do I have to remain on ICS bootloader to do a restore?
Is NVFlash truly unbrickable? A glance at this forum shows loads of bricks, would this have sorted their problem if they backed-up first?
Thanks!

I played around with your instructions today. Ran into 2 snags:
1. Using blob UI, I typed "u" for unpack, then "blob." It returned with "cannot open 'b'";
2. Typed blobunpack.exe blob. Gave me all the files as shown in attached thumb, except LNX. Where did I go wrong?

I'm having problems with the UI myself. It worked properly when posted. We probably have had an update that broke the UI. I'll remove the link. The tools are easy to use without the UI.
You don't have an LNX extension but you do have boot.img which is the same partition. Did you possibly rename the file and forget? Packing and repacking are still working properly for me including LNX.
I also updated the download link. The link now shown is for the version that can sign when blobpacking.

No recovery
Hello Everybody,
I followed the instructions to restore my device however when my tf300t reboots I can't get the device into recovery mode. It will start up into android or if I hold the volume down during restart it says "platform pre os boot configuration cold booting linux". I download a ICS twrp img recovery file from here for the tf300t. "http://techerrata.com/browse/twrp2/tf300t"
My only options at this point are to enter APX mode or boot into android.
If somebody could help me install a recovery so I can use custom roms I would appreciate it!!!!!
Thanks,
Mike

Use nvflash again to flash only twrp.
or
Other options
fastboot -i 0x0B05 flash recovery twrp.blob
fastboot -i 0x0B05 reboot
or if rooted
adb shell
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4 Then reboot to complete installation.
adb reboot
I use 2.5.0.0 twrp as I have problems with 2.6.0.0.

Thanks tobdary for replying back. I tried other versions of the recovery but none seem to work. I can't do that fastboot method because I dont get the fastboot option when the I hold the volume down and power like I did when the tablet was bone stock. I can't get su access on the tablet because its not rooted anymore once I reinstalled the nvflash rom so I cant try and flash recovery that way either. I'm really stuck and not sure why this isn't working!

Try flashing stock recovery and recheck your bootloader menu for fastboot.

Do you know where I can find the stock recovery? Is it something ziped in the original rom file?
I was able to root the tablet using a program that that uses a exploit while android is running. I then could adb through su access and flash different twrp recovery blob files to the tablet. Though the tablet rebooted and showed a blue line with recovery being installed when I restarted I have no options to load recovery, fastboot, or linux. I'm thinking the bootloader is corrupt. I own a tf201 and might have accidentally used one of the hairybean 2.3 (4.2) bootloader updates for that device on this one. Is there a way to get my bootloader back to the original and maybe that will fix it?

The first thing you flash in this guide is the bootloader. nvflash --resume --download 4 blob.EBT
With nvflash you can flash only what is needed for your situation. If you feel the problem is the bootloader you can flash just that and try again.
What you describe sounds like stock recovery is still working on your tablet. If flashing the bootloader does not help I would use stock 9.4.3.30, unzip once and place the remaining zip on your internal sdcard. You may get an update notification. Accept it and let your tablet do the work. If you don't get the notification reboot your tablet and you should see it then. Doing this will write stock bootloader, recovery, etc.
Stock recovery is the blob.SOS when you blobunpack. Just use the stock 9.4.3.30 blob and use the resulting SOS (recovery.img).
TF300T Bricked accessible using APX Mode.
Hello @tobdaryl
I have read your thread fully, but my case differs a little bit and need your advice:
I have unlocked ASUS TF300T.
I cant access FastBoot or ADB.
I can access the APX mode.
The ASUS shows only the ASUS logo when powered on.
I don't have BackUp of anything.
I have flashed everything from my ASUS, even the recovery. (I was novice):angel:
Any suggestions or advices please?
What should i do and from where shall i get the needed files, etc...
Thank you in advance.

I have read your previous posts in addition to this one.
There are four vehicles to restore your tablet. (some things can be done within android but you have no access)
1. recovery - stock or twrp
2. fastboot
3. adb
4. nvflash
I notice you also posted in my guide for accessing adb, fastboot, and apx. You were unable to access fastboot, adb, or recovery with those methods.
I don't know of any way to recover through apx without nvflash previously installed and you have no access to the other three methods.

Thanks! *I'm glad you found the info useful.
So he was following some random youtube video that was years old so it probably was outdated...
the phone state is currently unlocked, not unrooted yet..but with clockwork mod .
it responds to fastboot commands using the nexus toolkit by wugfresh but i can't get adb to work? all the guides i see say you have to have the phone booted normally before installing it and we can't do that
any help is appreciated
Your situation is a bit unclear, Is the phone boot looping? What you can do is flash a factory image while the phone is on the bootloader mode using Ncry toolkit or something similar. This way doesn't require the phone to be on or have any flash files already on the phone.
hey thanks for relying so fast, yes it is boot looping, ill try what you said now and update status, thanks again
edit: where would i get the factory image? does that toolkit download it for you?

you didn't go into the stock recovery after unlocking bootloader
here is the factory images page - https://developers.google.com/android/nexus/images
you could probably just flash the recovery.img in the image-*.zip file to recovery, then go into recovery, wait for it to do it's thing then flash clockworkmod, philz or TWRP with the toolkit and do root etc.
you can also just flash the factory image, then do the stuff with the toolkit (easier)
sorry if I've confused you o.o
Easiest way to do this is to use Ncry (http://goo.gl/l0iuEn):
1. Put phone in bootloader an connect phone to pc with Ncry ON.
2. Click on the one click menu.
3. click SR mode.
The programme will automatically download the files and do the flashing, when finished the phone will auto boot.

You will need a way to copy Stock Firmware file to a SD Card
You will need a few files
Drivers
Stock Firmware
update-kindle-37.5.2.2_user_522054520.bin.zip - AFH -
Custom recovery I used Twrp
UPDATE-SuperSU-v2.46.zip if you want to root
Open Gapps zip if you want Google Services (I suggest ARM/5.1/pico)
Instructions
Install Drivers
Change Stock Firmware file extension from .bin to .zip
Copy Stock firmware to sd card
Insert SD Card in the KFFOWI/Ford
Boot to Fastboot Mode
Boot Custom Recovery
In Custom Recovery, Install Firmware.zip, SuperSU.zip, GApps.zip
Reboot
I covered most of these steps in

Can I perform a full, stock recovery on 5.1.1?
I lost some stock Amazon apps (launcher, Amazon Video) during Root using AutoRootScriptFirev4.12.
I have used ADB to restore the 5.1.1 Update but it returns still missing the apps deleted during Root and no Launcher.
Both factory reset & sideloading the 5.1.1 Bin restore my tablet still with missing components.
Is 5.1.1. only an update and not the full restore?

I installed the OS from Amazon OS 5.1.2 to Android 5.1.1. (Lollipop). It worked a few days and started intermittently working sensor and I decided to reinstall another Android 5.1.1. After reinstalling the tablet does not turn on. Then I went in fastboot and through ADB installed Amazon OS 5.1.1.
The result: the tablet when turn on does not show screen AMAZON, that is does not react to pressing the power button. When connected to the computer constantly appears and disappears "PreLoader USB VCOM Port".
Tell me, please, how can I restore the tablet after that?

i have the same problem. So far the only fix is to order a used motherboard on the web and hope it isn't bricked. Amazon should really release a program to return the device to stock from the PreLoader USB-MTP mode.
There is this thread for the possible solution:

Amazon has a generous 'no questions asked' exchange policy during the warranty period which runs 90 days to 2 years depending on model and region. Device is not intended for enthusiasts as evidenced by aggressive lockdowns. Why would any company in their right mind release such a tool given the target audience?
Bricked my tablet but I'm able to boot into fastboot mode
Hello,
I have just softbricked my tablet because the wrong OpenGapps were flashing.
The problem is I can't start a custom recovery because the boot loader is too new
And I can't access my stock recovery because I've tried flashing TWRP from it in the past.
What can I do now? As I said earlier, I can access the device using Fastboot commands, but I don't know how to get at least one ADB interface working on the tablet so that I can upload the stock image to the device.
Thanks for any help!

So what can I do now? As I said, I'm able to access the device with fastboot commands but I don't know, how to get at least a adb interface running on the tablet so I can sideload the stock image.
Many thanks for any help!

You will not be able to reload stock FireOS from fastboot as the necessary commands have been disabled by Amazon. Pretty much game over if you can not access stock recovery and bootloader version is >5.0.x.
Can you describe "softbricked" symptoms in more detail? At what point during boot process does device hang/loop?

When I press the power switch, it turns on. Then the Amazon logo appears and after about 10 seconds the screen goes black again. The whole thing then repeats itself in a boot loop
i flashed stock update-kindle-37.5.2.2_user_522054520.
following a link in the forums
had to do it for pokemon
can i just flash any newer version as well this way or will ability to fastboot boot twrp then be gone?
thanks for any help

Hi @Teligen,
There is already an ongoing thread, about this very topic over here... that shows it's current status.
At the moment, we're just about getting there... but it's by no means an easy feat yet....
Cheers, Lister

That twrp is for a different device. I wouldn't flash it unless you have a backup of your boot/recovery or stock firmware for your device

The only difference is that F has no Modem and SIM Slot for mobile Data but it works fine.
I only use it to root the device without actually flashing it.
Just put the twrp image in your ADB Folder on your PC, then run fastboot with the command:
Fastboot boot twrp.img
This uploads twrp on your device and boots it to twrp. You can leave the system recovery untouched and flash supersu for rooting.
The bootloader has to be unlocked of course.

Ok cheers. Appreciate the info. So I'm wrong in assuming the Tb3-850f came with an already unlocked bootloader? Like many lenovo tabs
Edit. Also the yoga yt3-850f is a different device to lenovo tab3 tb3-850f

No, no. You have to unluck it via fatboot as well.
1. Enable Developer Options
2. Enable "OEM unlocking" Option in there
3. Reboot to Bootloader (Restart and hold down Volume down)
4. Run fastboot oem unlock-go
Next, the Android Bot and a process Bar appears on the tablet and does it's thing. Once that's finished the Tablet restarts and enters the initial Android Setup Screen. So it unlocks the bootloader but ALSO performs a factory reset.

Yea I think your referring to the yoga tab 3, not the lenovo tab 3
Lenovo_TB3_850F and Lenovo_YT3_850F
I can see why one would get confused lol

Yes, I have the YogaTab 3 (X50F). But there probably won't be any harm done unlocking the device and booting (not flashing) from the afore mentioned twrp.img.

That's a good point, fastboot boot is a safe method

Here is TWRP recovery and a SuperSU 2.78-SR3 flashable zip for the Lenovo Tab 3 8/TB3-850F.

Credit goes to @Hemphiz for his tutorial and files on TWRP + Root for the Lenovo Tab3 8". https://forum.xda-developers.com/android/general/guide-lenovo-tab3-8-tb3-850f-t3559786
Brilliant! Thank you very much. Just got this Tab 3 yesterday and love it. Will love it even more with root+adaway.
It works great. I used adb & fast boot to unlock the bootloader & then boot from twrp image on PC and install SuperSu. Have been using Samsung for a long time but fast boot is much nicer, especially being able to boot a recovery without modifying partitions or filesystems on the device.
Hi
I have been unable to find a TWRP build for my Android device (a Lenovo TB-X306F) anywhere online. I'd like to get into custom romming, which is pretty much impossible without TWRP. Does anyone know if there's a stable, reliable build of TWRP that has been tested to work with this device that carries the smallest risk of bricking my hardware or getting caught in a boot loop, and will allow me to interface with TWRP via ADB shell?
Thanks in advance!

yeah it was very easy -- download the current firmware for your tablet, extract the boot.img
install the magisk app, then run it..
copy the boot.img to the tablet, tell the app to patch it, download the patch BACK to your pc..
then put the device into fastboot, and run
fastboot flash boot boot_patched.img
BTW, I could not find a TWRP that worked with our device.. it was not necessary anyway.. flashing the boot partition was enough

Ok a bit more information for what I tried like 3 months ago
- I downloaded adb and fastboot
-adb was working fastboot was not
-i read about mtk drivers and that they are the problem I did download them but still my tablet doesn't show up in the pc (fastboot devices)
I can't get past that step
when you say that fastboot is not running, why is that?
what error do you get? you know you need to put the tablet into fastboot mode before fastboot will be useful,, right?

Try different cables (or drivers if you are using windows).. they make a big difference.

No sorry - I use Linux which doesn't need drivers.
