hmm.. no one can't help me to solve this...

Hello roomraditz, right now this issue doesn't have any easy solution if you are entering on the APX mode means that the firmware has been corrupted anyhow and in order to install anything in this mode you would need to recover some keys that are not available at this moment.
I have been working on find these keys but I didn't have any result yet.

Xoom bricked seen as APX in devices need drivers

Bricked Xoom built a program cable but fails to install drivers when connected. I tried going to devices and troubleshooting searched for drivers but none were found.
Any idea of what i can try next?
Have you downloaded drivers from motodev?
Prior to the bricking, could you connect to your computer?
It will connect but it just shows up as APX in the devices and says its missing drivers. I went to moto and downloaded USB drivers but still does the same thing. The xoom does nothing when plugged in.
Windows 7 or XP?

Windows 7. I did manage to get some drivers to install. Don't know if their the rite ones though. I clicked on let me choose such drivers, found some in SDK for htc,Samsung,and Motorola. Chose Motorola and it had several adb drivers clicked next and they installed. So now it just shows it as APX in the devices but no longer has the missing drive issue. Still no sign of life when trying adb or fastboot.
What mode is it in when you are attempting to connect it to your computer?

It's just a black screen. Won't turn on at all even when pressing volume+power. All it does is the white light comes on when charging. Can't get recovery mode or fastboot.

I have the same problem.. doing my head in trying to fix it. I have tryed everything i can think off. Anyone out there know how to fix it in apx mode using a factory cable ?
Did you ever find a solution to this issue?
I currently have a black-screen bricked Xoom. I have tried all the 'soft-unbrick' methods, I can _NEVER_ get anything to appear on screen. The only signs of life are with a 'factory cable'
With this 'factory cable' I am able to see 'APX' in my Device Manager. I can make it 'reboot' by doing the volume up + power which makes the device disappear and reappear. No other key combinations have any effect.
I am able to install either the Nvidia NVFlash drivers. However NVFlash doesn't work. Possibly due to a lack of SBK (Secure Boot Key).
I am also able to install the "Universal Naked Driver" which makes the device show up as an "Asus Transformer APX" However neither fastboot or adb seem to see the device.
Does anyone have any suggestions how I can unbrick my Xoom?

Dear all,
I got the same thing.
I installed the driver from nvflash drivers. And I ran several commands to try, it showed no bootloader was specified. I guess maybe I damaged my bootloader. Does any of you unbricked your xoom?
Here is a link to my post, which showed my tries.
http://forum.xda-developers.com/showthread.php?t=1838002
Anyone could help us? Thanks a lot.
Wow, i've been on that Wagon for a long time. http://forum.xda-developers.com/showthread.php?t=1838002 Now I just gave up cause I don't think anyone has gone past installing the drives after it detecting as APX.
Thanks for your kindly reply.
So, you mean there is no hope.
Actually, I sent it to another MOTO local service center again. After one week, they told me they tried to restore the software in two steps, but only the first could be done, and then went back to brick again. And they thought there might be some damage on “the kit” of motherboard, and if I want to repair, the whole motherboard must be replaced totally.
If you still have the bricked XOOM, would you please try to draw the BCT and config.cfg from your device?
Again, I did another search. Although there is no available bootloader.bin, BCT and config.cfg for XOOM, I guess there might be possible to use SAMSUNG P7510's files, because the hardwares are almost same, and it's heard that P7510 could use XOOM's ROM.

Another Bricked TF300

Hi, good people. I have bought a TF300T bricked last week, the old user has stock OS, tried to root and failed.
Now im fighting with that. When i turn on the tablet, it stuck at 'The Device is Unlocked' with Asus n' Nvidia Logo, after a minutes it reset and keeps in a constant loop.
I tried to recovery [vol down etc etc] and no effect, i tried with a few of tutorial and nothing.
I connected the tablet via APX [VOL UP + power]. PC recognized it but i stucked in this. Tried to fastboot and stays in 'waiting device'
Someone with ideas? Thanks frr all and sorry for the inconvenience.

PC operating system?
Drivers for fastboot and adb loaded?
Look at my signature about universal naked drivers.
Also about getting into your bootloader menu.
APX will be useless to restore.

Did you actually use the link to attempt the bootloader access?
Did the drivers properly install?
Do you have an sdcard for this tablet?

I'll assume that means all ten methods to get into the bootloader failed.
If the adb drivers installed we may have a chance.
You didn't say about the sdcard.
At the moment are you still stuck in apx or bootlooping.
Sorry but I need a place to begin.

i have a sd, it doesn't have info [isn't from tf300, it doesnt came with]. When i introduce it into eeepad i can't access the storage from windows.
I can only interact with the tablet when i turn it on with VOLUP + POWER then is when windows ask me for drivers, now i have installed ADB drivers.
sorry for all dude. And thanks.

No problem we just need to get a starting place and have as much in our favor as possible.
I don't believe adb works in apx mode but we'll give it a shot.
No sdcards come with the tablet.
Go into apx mode (volume + power).
Go to your adb folder with cmd and type
adb devices - press return or enter
If it is working we should get your serial number in return.
Now get out of apx mode.
type
adb devices - do not press return yet
watch your unit and when the screen goes black and before it lights(rebooting) now press return
Tell me what is returned each way.

I have some bad news for you.
Without adb or fastboot access I don't know of anything else to be done.
If you could have gotten into the bootloader menu we would have had a chance.
Maybe someone else will read this thread and have more ideas.
I'm sorry.
Good Luck!
same problem here. i have a tf300t and can only access apx interface.
I got into this mess, after by "accident" choosed the "wipe data" option present on the bootleader.
!! adb, fast boot do not work!! "power key + down button" dont do anything!
i'm getting a bit resteless because no matter were i search on the web i can not find anything suitable on how to resolve this issue...
there are some youtube videos that show a solution for tf100. it seems the same problem.
http://www.youtube.com/watch?v=CwvfNIHCYlQ
there is also a tool for tf100, called easy flasher. to bad it does not work for tf300t
http://forum.xda-developers.com/showthread.php?t=1688012
i think it is a question of seaching and waiting. someone will help and get or point to a solution. because if we google for tf300t bricked that are lots and lots of links stating this issue...
what a mess...

Do you see anything after resetting by holding volume down and the power button? If you can get the tablet into fastboot mode you may able to revive it. If you can, ask the previous owner which version stock Android he was running before he tried to root it (it matters!).
This method worked for me!

[Q] The Device is unlocked Message and stuck at ASUS logo

Hi all,
I have an ASUS TF300T.
A friend of mine tried to root it and install a new rom. He said he followed steps that he found on XDA and was trying to flash a new JB rom.
Having said that, now the tablet is stuck at the ASUS Logo during boot and there is a message on the top left "the Device is UnLocked"
Nothing happens!!
I tried holding POWER + Low Volume button and it does not get into bootloader. ADB and Fastboot does not detect the device. Even Windows and Linux do not detect the device.
So i tried POWER + increse Volume button and it gets into APX mode. I used the Universal Naked Drivers on this site and windows detects the device.
But the question is how do i restore it or how to reformat it ...etc.
Is there a way to use External SD card to get help in this situation.
Can anything be done from the APX Interface ?
These are the links that my friend has followed ...

[Q] Cannot repair Hardbrick

Hello Community,
I joined XDA because I have a bad problem with my One Plus One.
It becomes Hardbricked =S
So I started to ask Google for help and there was this Thread:
//forums.oneplus.net/threads/solution-recover-from-hard-bricked-oneplus-one.104943/
So I tried it but I was not able to solve the Problem. At beginning of the Tutorial I have the problem that my device ist not recognized by the "chinese" software if I use VolUp + Power, but if I try it with VolDown + Power I can see it. So I go on with the tutorial but then I have to click the big button in the upper right corner and the line with my One Plus goes red, so I read this is wrong. After some more try's I gave up.
I think I have no driver problem, because there comes no error at or after the installation.
I use Windows 7/8.1 and the driver from the downloaded ISO not Qualcomm, because I don't get them work. Also I tried Windows XP as VM but there I was not able to install any driver =/
Now my question are there some more tricks and tipps to get Color OS installed?
Thank's for your help.

If you can get into bootloader mode you are golden. Just reflash stock firmware, such as cyanogenmod 44S.
Thanks for your answer.
I think I am not able to reflash something, because if I try to go into bootloader or recovery or simply to boot I only hav a black screen =\
In cause of this I used the tutorial from above.
Is the device recognized on the computer at all?
I am realy sorry of such an late answer, but I get into some trouble.
But b2t, yes the device is recognized as "QHSUSB_BULK" in Hardware Manager, also Windows recognize some partition wich should ne formated. I never have done this at the moment ^^
Have you looked here?

HUAWEI P40 Lite Soft brick

Model:Huawei p40 lite
Hello, recently I flashed most propably bad firmware version and now the device seems to be soft bricked.
Black screen, no vibration while pressing power button, nothing.
However when I connect phone to PC, it does detect a device, I download HiSuite and device gets detected as Sooner ADB interface, but via HiSuite shows that recovery is not supported within the model.
ADB is also installed but devices show no devices at all.
When I press power button and volume down it seems to enter another state but device name/driver is the same. No fastboot.
It seems like it is not dead at all but I would have to use somekind of flash tool.
Any ideas would be appreciated
Thanks
Hi, is there a solution?
I need a solution to. Someone?
I am in the same situation. Is there someone to help?
