[Q] Both USB Debugging and ability to mount gone - Legend General

So, last night I decided to install ali ba's CM 7 build. After a few false starts, I ended up with a boot loop. Since then I reverted with fastboot using a LEGEIMG.zip, and I can't mount my microSD card via my phone anymore. USB Debugging is all but gone, I can access it for maybe a minute and then it dies.
To be clear, the icon on my phone indicating that USB Debugging is active, but `adb devices` stops showing it after a minute or so.
When I plug in the phone, Windows tells me "USB Device Not Recognised". I've tried removing and re-installing HTC Sync.
I'm lost for where to go right now, suggestions?
Thanks

I had the same problem. I'm not sure how to get ADB back, but I can help you with the MicroSD mount problem. Go into Fastboot on your phone, with it plugged into your computer. In the cmd prompt navigate to the folder where adb devices is and type fastboot oem enableqxdm 0
Let me know if you figure out the adb bit. I'm still trying to fix it.

[Q] Yet another boot looped N4, tried all, need expert help to recover user files..

I have been using the stock 4.4.4 for a while with some occasional crashes and reboots in Skype. Then one day, when I turned on my device, the boot loop struck out of the blue! I had only installed some apps, nothing ROM related was changed.
I need some expert help with recovering my user files (some images in non standard folders, game saves etc..)
Symptoms:
*The device is stuck at the circle logo and won't boot up.
*The boot loader is unlocked, USB debugging is enabled and the device was rooted before with version 4.2, upgraded to stock after that at least twice and lost root.
*When connected to PC, auto driver loading fails with MTP but I hear a USB connection sound when I turn on and off the phone. Although, the device is not recognized in "My computer". I see an "Android Device" and/or "android bootloader interface" in Device Manager.
What I tried:
*Tried wugfresh's toolkit and re-installed all google drivers but when I run adb/fasboot commands from within the toolkit, my device is not listed in either list. I get a blank list of devices.
* I can get to the recovery mode in stock boot loader after the "No data" screen and tried wiping user cache, did no good.
What I would like to achieve:
* Ideally I would like to be able to boot into the system without losing any user data and run my backup app and/or connect via USB to backup files on PC.
* If above wouldn't be possible, accessing files externally would also do as a last resort.
Any help is appreciated!
Thanks

Do you have clockwork mod installed?
You might be able to pull the important stuff over ADB when the phones in recovery
If ADB on your computer recognizes and can connect to your phone you can probably pull off the files

Thanks for the suggestion. As a matter of fact, while waiting desperately for a reply here, I tried to flash TWRP recovery and managed to adb pull data and sdcard directories over to my PC. And then a factory reset brought my device back to life.
It's a bummer that all of my home screen settings and account settings are reset..
The question now is how to copy over the backup data back to the phone..
adb push will put them back, but your phone will probably mount normally and show up in 'My Computer' now so you could just do that.

I'm glad you were able to pull off the files from the phone.
You can use the adb push command to put the data back into the phone
Try this : adb push /path/to/local/file /mnt/sdcard/path/to/file
or
adb -s [yourdeviceserialnumberhere] push /system/[whateverdirectory]
You can check out this too : http://forum.xda-developers.com/showthread.php?t=2167651
The post clearly explains multiple adb commands
Hope it helps!

Nexus 7 with no OS and no adb connectivity. Sideload doesnt load.

I need some help guys.
My Nexus 7 all of a sudden stopped sending data through usb OTG and i tried to erase cache through TRWP but ended up deleting the OS. Now I am stuck with a device with no OS. I cannot mount the USB for my computer to recognise it so that I can restore it. I tried ADB sideload but it doesnt load and gets stuck on starting...
If I click on Mount, I cannot click on the USB-OTG box. My computer does have the correct drivers for the USB as it used to work on it before but since the OTG stopped responding to data I am now stuck and cannot push a restore image to the device.
Any help would really be appreciated.
Many thanks.
I've tried almost everything I can think off. I tried different OTG cables, different computers. None of the computers even detect a device as plugged in. Whether I boot into bootloader or recovery I just cannot get the PC to even acknowledge the fact that something is plugged in. As a result I am just not able to flash it at all. I tried NRT with the soft-brick option but that fails too because it says no adb connectivity.
any help please?

System does not mount and i need to extract files by ADB

hi
While working with the device, it reset without prior warning, and since it trying to start and when the Google logo disappears and the animation stage arrives, 3 seconds later it turns himself off.
I entered into the Recovery mode and cleaned Cash - did not help
I thought to take out the battery in case something might be stuck in my memory but I still have not done it because when I dismantled the small panel (on the part of the camera) I accidentally turned on the device and it showed me that it upgrades the apps, which was a good sign for me so I closed the panel and waited for it to finish The 147 applications. At the end he turned himself off
I did not proceed with the matter of dismantling the battery.
I have the default recovery, I did not install recovery applications that expand the possibilities in the recovery mode.
and i don't remember if i turned on the USB debugging.
I decided to transfer the files (pic's, whtsapp) by ADB befor i try the factory reset
but I get sideload instead of recovery
C: \ adb> adb devices
List of devices attached
R ********** sideload (I changed the stereo to asterisks)
and every command I try to run I get
error: closed
Does anyone have an idea of how to copy files or repair the system ?
thanks
You should be able to bring it to fastboot mode by powering it off, then holding Power, Volume up an Volume down until the robot appears.
From there you should see the device with "fastboot devices". You might need to install some drivers at that point.
When in fastboot you should be able to start TWRP with "fastboot boot twrp-3.1.1-0-manta.img". When in TWRP you can see /sdcard in Windows or you can start Advanced > File Manager and copy your data to a USB stick.
thanks bornheim2
i succeeded to load the TWRP
but when i unplug the USB for plugin the OTG the screen start blinking and the devices turned off.
i have charge the device all night
so my guess is that my battery is bad.
can i use usb a male to usb a male adapter
or Hittime smart 3 in 1 Micro USB OTG/Sync/Charging cable
( i can't put links )
to connect the device with OTG to the computer for power and for transfer data to the computer ?
thanks

You should see the device in Windows when TWRP is running (and the device is charged by the PC). That should be enough to save your files.
i don't see it on windows (computer)

That might be a driver problem. Do you see it in Device Manager on Windows? Probably with a yellow triangle?
it's good in the devices manager "Android Bootloader Interface"
but after the TWRP it upload, the devices no longer appears in the device manager
and the screen is still blinking
when i run the "fastboot boot twrp-3.1.1-0-manta.img"
it turn in the device manager to "Android ADB recovery interface" and after 1 sec is disconnect

Nexus 6p boots into fastboot, not detected by pc

The other day I was trying to flash my 6p back to stock so I can sell it, and I was flashing everything through cmd, until all of a sudden cmd stopped working towards the end for some reason. Now my phone only boots into fastboot mode and is NOT being detected by my pc. When it's plugged in, the fastboot menu says to connect the data cable. I've tried restarting my computer and reinstalling the drivers, but nothing seems to work. When I go into cmd and type adb devices, nothing shows up when it's plugged in, and device manager doesn't show any changes whether it's plugged in or not.
I've called local cellphone repair shops, but apparently if it's not Samsung or iPhone they can't help
Btw I've searched the forums and haven't found a solution to this problem.

H E L P - bootlooping, COM does not recognize phone

Hi everybody,
ill try to make it short:
My 6p has entered into the bootlooping mode.
I have never unlocked the bootloader/changed ROM/kernal.
After I let it bootloop until the battery is dead it's changing from bootlooping into blinking red dot. Then when I charge it for a couple of minutes it comes back to life after 10~ min it's bootlooping again - so I have a window of possibilities to play with the setting. In that window I have used the "OEM unlocking" option.
In the bootlooping state when I boot into the bootloader and connect it into the PC the device doesn't recognize that it has been connected and a PC ,and the PC recognize a entry of new device but doesn't recognize it is a Nexus 6p.
this situation is the same when I connect the phone when it is alive.
I have installed adb and fastboot with this software
https://forum.xda-developers.com/showthread.php?t=2588979
with the 1.4.3 version it shows in the end of the process "0 files copied" and then I tried the 1.3 version and it showed that 4 files were copied but it also showed an error.
I have also downloaded ADB from google site but it does not work either.
When I try to open the powershell in a folder where I have downloaded an img and type in a fastboot command the computer doens't recognize any type of command.
So if anyone can help me ill be glad.
Thanks in advance,
Matan.

What is the new device identified as....Qualcomm HS-USB QDLoader 9008? Your phone may be stuck in EDL mode. If that is the case you need to search XDA and attempt solutions for that problem first.
Did you previously have your PC setup properly with the correct USB drivers and it was working OK, or just now trying to get your dead phone to communicate? If the former it may be the EDL issue above. If it was the latter, the communication problem may just be the drivers were never set up in the first place. Have you tried a different cable or port on your PC, or another PC?
With no access to the OS you will be unable unlock the bootloader or access to ADB because those have to be enabled FIRST in the OS, so there's no helping you here until you can actually boot into the OS. Do you have access to Recovery mode? Tried a factory reset? If you don't have recovery, that was a major omission.
