I need a little help my device is stuck in apx mode (blank screen with power led on) i have uid (cpuid) and sbk i have read a lot fom this forum and have all the tool to root, flash, load.. But my main problem is that when i reset my acer a500 and the usb is attached the windows 7 recognizes the driver and (sound pops up) and the driver (acer picasso usb boot recovery driver) is there but no tool e.g apxtool or fastflash or ics rooting nothing works or regocznies the device coz when i press any option or press the key to continue the drive drops and vanishes from the window usb list in device manager and i have to manually reset acer again to get the driver back but still no use as command prompt tells me that no device is attached or found. Please help as this acer is my wifes gift to me and im trying hard to get it back its totally dead

I wanted to use nvflash to bring back to clean slate. Could not get the USB driver issue resolved in Windos 7 or XP, Read the threads, just did not work. Also noticed that the USB connect to the GTablet stopped working, it woriked fine for before trying adp. Tried Linux and the device is not seen using LSUSB did see the device is I tried via USB debugging mode. I power on and hold the vol- button see boot screen then unit goes black. No usb connect to PC either after trying.
Reset the device to stock with CWM and PC USB comes back. Is there a utility or something to check the ADP functionality at boot level, has anyone had USB issues that can help? Is it a possible hardware issue?

Try USBDeview: http://www.nirsoft.net/utils/usb_devices_view.html
Disconnect the G Tablet from your PC. Then run USBDeview as administrator (i.e. right click and Run as Administrator in Windows 7). Then uninstall any drivers related to the G Tablet.
Now plug in G Tablet and it should be detected again and you can point it at a properly working ADB driver on your PC.
Have done that, but it seems that it is something on the GTablet that is causing the error. When is is malfunctioning no USB connections work and driver issues pop up, after set to factory the USB works and driver issue for storage go away.
So far I can tell that adp mode from power and vol - unroots my tab and I can not connect to pc. After re-rooting I can connect. Linux can not see device in adp mode.
Update. Returned the unit to sears for a new one and problem solved. I must of had a clinker.
hi
i bought a transformer last night
it has B50 serial number
it has 3.0.1 hc and i update two times with OTA and now it is on frimware 8.6.5.13
the problem is that i cant get into APX mode
i turn it off and press vol up+power same time but screen is blank
sorry for my language
It's supposed to be blank
Its supposed to be blank. If your in windows open device manager and see if its installed under USB or Portable Devices. Make sure you install the correct drivers for it. If you are running linux type "lsusb" into console to display connected usb devices. Also when using adb you can do "adb devices". It will show if your device is connected "properly"
thank you guys
FIXED
Ok here is my problem and I will try including all the relevant information that I am aware of. I can't see my TF300T when I enable fastboot mode on the tablet.
1. I turned on usb debugging in tf300t settings
1. I unlocked the tf300t using tool from ASUS
2. I installed the android sdk kit
3. turned off tablet
4. Plugged tablet into usb
5. Held power off and volume down ( boots up with 3 icons. RCK Android Wipe ) pc comes up with failed usb device. I go into device manager and
under usb controllers it shows unknown device. I click update driver select the naked driver winsub and it says it is not compatible. I tried deleting device and rebooting etc but no matter what I do or what driver I use I can't get the computer to recognize the tf300t in fastboot mode. It will work fine when it is not in fastboot mode I can transfer files all day long. but no matter what I do I can't get computer to recognize the device in fastboot mode.

asus H87-pro motherboard

I am really befuddled and could use a hand.

Just a quick update. I used a different computer that I had never plugged the tf300t in and before I plugged it in, booted it into fastboot, It showed up as a fastboot device and installed the naked driver. So that problem is solved.

How to set "usb debugging" on my softbricked phone.
My phone shows as "android phone ->android composite adb interface" in device manager.
When I try open command windows and type : "adb devices" at platform tool it not shows my device.
I've installed adt bundle and qualcomm driver on my win 7.
I tried install pda net-32 bit but I failed because pda net doesn't find my device.
I can not enter to recovery mode by press power + vol up it stuck on the red screen with little word "recovery" at right up at the screen, just it.
By pressing power + vol down it just show boot logo.
Can I make it show as usb mass storage devices other than android phone in device manager? So I can flash my backup rom.
I try search related topic in this forum but my problems is different.
I hope somebody like to teach me to solve my problem. :crying::crying::crying:
Thanks in advance
as i know Your phone should must be open in download mode to flash rom
if you are not able to open download mode then you cant do anything
that sucks
damn that sucks:crying:
My lenovo a3300 was flashed few months ago due to some rom problem by service center (and it was showing rooted while I checked using few apps).
Yesterday I tried to upgrade my firmware(available in phone update) but while restarting, it showed the boot screen and then I tried reboot now option. But then No command and a lied down android bot appeared.
None of the other option worked, and after 30-45min the screen became off and from then showed nothing. I have tried every possible button configuration but they failed.
I have inserted it into computer and system recognized it as a "MTP USB device" under portable device(win 8.1) .
But today it showed the start screen too(finally, hope ) and I tried to reboot it by holding the power button. But the same screen returned after a vibration.[it used to vibrate when switching on]. When I right clicked the "MTP USB device" It was showing update driver, uninstall etc.
But after I tried to reboot(also after disconnecting and reconnecting it) , there are only one option i.e. "Scan for Hardware change".
I have the sp flash tool and the stock rom from xda site. I have also installed VCOM driver (android gadget vcom driver) but while flashing the download is not starting, though no error or popup showed.
How I can get my tab work again? pleaaaseee help
Thanks in advance
