Apx Device and USB device not found. Please help! - T-Mobile LG G2x

Ohkay I am trying to restore my g2x using oneclickrecovery. I successfully do all the steps until I click on flash stock rom. I'm the beginning, when my hold both volume up and down and plug it in to the computer it will not say Apx Device. It would say like USB device not installed. But then I follow the steps anyway and it says Nvidia boot for mobile devices then I take it out open oneclickrecovery then I select flash stock rom. There would be a blue window and it would say USB device not found. I would look at my phone it wouldn't say S/W upgrade.
Is there anyone who can resolve this problem? I need my phone back.

[Q] help! got a real brick, cant go APX

i've just flashed prime 1.9 mobile data ver over CWM. have to say the whole proccess ended faster then normal. after rebooting i get nothing. black screen.
tried holding power for 10-20 sec, even 30. nothing.
so tried going into APX mode and nvflashing through pc. but when i'm doing that the pc recognizing it as "unknown device" and not an APX.
so i've realy got nothing. and i cant communicate with pc to nvflash.
obviously i tried manualy install APX driver from nvflash folder. but still get unknown device.
please help!
what should i do?
im not a newbie i've done those things dozens of times. (nvflash, apx, cwm..) but i've never faced a totall brick
so you already had nvflash connected to device before it is bricked so you are sure all is setup corectly ?
cause it is a real pain in the but that when the tf is in apx it just looks dead.
If that is the case than I dont have a clue because nvflash is kind of a last resort
Uninstall the drivers, reboot, install the drivers again and try for apx, if its a no go then reboot pc and try for apx.
Sorry i cant be more help.
Edit - Make sure the TF actually has some juice in it. Leave it on charge for a couple of hours.
i've done nvflash before and i'm familiar with the procedure.
about uninstalling drivers and rebooting, maybe will help altough i've tried going into apx with other computers with no success aswell.
please help!
no one knows maybe theres a reset button or something inside the transformer. just a way to bring APX back!
if you can get back into revovery, try to flash again.
check md5sum yo make sure you have a good file

thats the thing. ive got nothing. the screen just stays black no matter what. so i thought maybe APX will rescue me but i now dont have even APX. is it even possible?
apx mode on ming leaves the screen blank and off. leave your tablet on a charger for a while to make sure it is charged, a couple of hours at least reduce as many errors as you can. if you have the apx drivers installed right when you plug it in to windows you will hear a beep saying you plugged a device in. You could also try to install the apx drivers again.

this thread has better instructions though.
have you ever installed nvflash drivers before...or is this the first time?
ive already told yall. i done this proccess before (nvflash and going into APX. i know the screen should stay off and only the computer should say APX device been detected or something like that. but the message im getting from pc is "unknown device" connected. and when i try to manually install the apx drivers from device manager by directing it to the nvflash folder where the drivers should be- it just stays unknown device and says that the most updated drivers for it is already installed
I'm having the same issue. I can't get into APX mode anymore. Just appears as "Unknown Device" in device manager.
I'm currently running PRIME 1.7. My clockwork recovery also fails to recognize the SD card, so I can't flash a new ROM that way either. I really want to switch to Revolver, but with no APX, it's not going to happen.
hmm maybi you can try it on a other pc. if you have luck it can be recognizedd
Unknown Device......?
Uninstall the drivers, reboot pc, reinstall fresh drivers, reboot pc, connect TF101
Next time use the search function or google.

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.

Feiteng H7100 Bricked

Hello,
I managed to brick my new Feiteng H7100 phone, i flashed wrong rom to it and got a greenish screen when trying to start the phone.
So i formatted the phone in SPFT tool "Format whole flash" and from then it stopped responding, i cant start the phone anymore, and the charging indicator wont light up when charging.
When connecting the phone to try and reflash it the computer recognizes that i have connected the phone to the computer, but flashing doesnt work.
It is the S7180 with 1GB ram.
I hope there is a solution to it and it can be fixed, iam not sure if this can be called had brick or soft brick.
Was very close to throw it out of the window yesterday, but then thought i can give it a chance
Thanks

Same mine is completely dead after I flash it - Its not recognized by the originally drivers in windows 7. Showing up as an Unknown Device.
if it is showing up as an device, it isn`t bricked. you need to get the right firmware and flash it again. force install the drivers for the unknown device or take the drivers for Rom you flashed. (e.g. flashed wrong preloader from ZTE to a Star device, need to install ZTE drivers)
While I don't know the specifics of the Feiteng H7100, I've "bricked" many an android phone and tablet. Fortunately it's usually easy to fix.
1) Reboot the device into CWM Recovery Mode (usually by holding power and volume buttons at the same time)
2) Plug it into your computer & run "adb devices" - if you device comes up as a Recovery device, then you're probably home free
3) Run an "adb push newly_downloaded_cyanogenmod_rom.zip /sdcard/" - the data location (/sdcard/ in this example) might vary depending on your device
4) Wipe Cache
5) Install Zip from sdcard and choose your new_rom.zip

I am assuming you have taken out the battery before the two button APX mode connect attempt. Try that if not. Also the first time you connect in APX mode you have to wait until driver install fails, then install the driver manually, then reconnect and it should work.

[Q] phone bricked and not getting detected on computer

Hi,
my friend's Nexus S was stuck in a bootloop. i went into recovery mode and hard reset the phone, so that the phone would come back to stock. however, the phone was being reset when the battery of the phone came off, switching it off.
the phone fails to start. there is no response when i try charging it. Also, it does not go into DOWNLOAD mode or FASTBOOT, so i cant even run any utilities to flash the stock rom back. adb commands as well as the nexus toolkit show that there is no device connected.
can anybody suggest me what to do?? i was gonna try odin but i read somewhere that it is only useful for custom recoveries, not to flash stock roms.
i've gotten some usb drivers mentioned at some thread, saying i would have to update my 'android' device listed in the device manager using them, but i cant seem to find any device mentioned in my device manager either.
any suggestions as to what i should do??

Something like this happened to me a week ago. I have Nexus S 4G. So, I ordered USB Jig from usbjig.com and now I have download mode. It worked! :laugh:
You can buy USB Jig from that site, or build it yourself, or borrow it from someone.
