[Q] fastboot mode inoperative

One N7, strictly stock, is recognised in Win 7 and in fastboot mode i.e no issue.
The other N 7 is root and unlock.
Under Win 7 home premium:
All of a sudden it is not recognised and device manager shows Android composite adb interface
but the windows driver is missing ( when I plug it Win 7 is not showing that a driver is installing).
There is no mention of N 7, not even a yellow exclamation point, let alone no mention of portable devices.
In adb mode the N 7 is recognised. Bootloader is accessible but fastboot devices does not show the N 7.
I cannot access CWM recovery 6.0.1.0 neither through bootloader nor from Rom manager.
This N 7 has stock JB 4.1.2 (JZ054K). I have installed SuperSU, Rootkeeper and Rom Manager.
Under Win 7 professional it is recognised, it shows in device manager and in adb but not in fastboot mode after going in bootloader mode, and still cannot access recovery mode (waiting for device if I try to do that).
I need help to solve this issue. Thank you
I prefer not to use a toolkit.

[Q] Nexus 4 factory rom deleted

Good day guys,
I need a help with my nexus 4, I had a rooted rom in my nexus 4 with clockwork mode recovery, I tried to wipe my data through clockwork mode but by mistake I did system wipe. Now there is no rom in the device, I can only access to fastboot mode and clockwork recovery mode, also I tried to install rom through toolkit but my PC & Mac doesn't read any device connected and no device shown in device manger in my windows 7 with using different usb cables and ports. I installed samsung drivers and adb drivers but still I cannot see the device in device manager.
Please if any body can help me to install rom back to my device.:crying:

In cwm there should be an option to mount the device as usb storage. Try that. It should let you plug the phone into the pc and simply copy the zip onto the phones internal sd.
If thats not working try this to set up the drivers. Then plug the phone in and boot into the bootloader/fastboot mode. The open command prompt and cd to the android-sdk/platform-tools directory. Then run the following command:
Code:
adb push /path/to/rom/on/pc/ /mnt/sdcard/

still not working
Still not connected to windows, I cannot do any thing with my device

Download any ROM and do the following:
1. Connect phone to PC when in fastboot
2. Install drivers (if required)
3. Flash latest version of CWM using fastboot flash recovery name_of_recovery.img
4. Reboot phone into fastboot using fastboot reboot-bootloader
5. Boot into CWM
6. Install drivers (if required)
7. Select 'Install via sideload'
8. Flash ROM using adb sideload name_of_rom.zip
9. Follow instructions in CWM
If that still doesn't work, go back to stock using this guide (and read ALL of it):

Thank you for your quick replay
My problem now that I cannot connect my device to PC, I installed drivers every thing and when I open fast boot or recovery mode and plug the cable, nothing indicates on my PC that there is a device connected even device manager not showing any device connected... I am stuck now, I cannot install any rom to get phone life back.

don't worry! the biggest problem would be that you had no drivers installed!
nexus are super easy to recover and you can play with them safely (except if you flash wrongs kernels from other devices haha)
do what my mate gets up in the post! and it will fixed it.

It's not that it's not showing, it might already be installed correctly. When you have the Nexus 4 connect in fastboot it will show in Device Manager as 'Android Bootloader Interface' under the heading of 'Android Phone (see attached)

[Q] Nexus 4 will not connect to PC and stuck in bootloop NEED HELP

okay so ive just rooted the device (nexus 4) running 4.4 kitkat and i had downloaded beanstalk and all the needed files to my computer, and followed this guide and wiped my cache, dalvik, and factory reset from TWRP recovery mode. i plug my phone into my laptop to install the ROM folders onto my phone and the laptop makes a noise meaning the phone is plugged in but the device is nowhere to be found in file explorer
i try to restart the nexus 4 to try with USB debugging on but it turns out it just keeps bootloop. so what can i do
please HELP??

Do you have a nandroid backup? Always have one. Boot into recovery and flash it. If you don't, shame on you, you're going to have to get your pc to recognize your device when booted into recovery and push your rom onto, or sideload the rom

Don't know if this addresses your specific problem but:
1. If you boot your phone into recovery, or just leave it at the bootloader screen, the Nexus 4 will not be displayed in Windows File Explorer. Only when it is booted to a full system will Windows recognize it.
2. Nevertheless, if you hear a tone from your PC that indicates your phone is connected to the USB port, then you can open a command window on the PC and start flashing your system images via fastboot commands.
3. follow the useful guide here (it is for a nexus 5 specifically. just substitute the appropriate Nexus 4 mako factory image)

Nexus 7 2012 Hard brick after downgrade?

Hello guys! I come now to the point ..
I bought the Nexus 7 WiFi only for in-car use .. When I received it, had the CyanogenMod 12.1! so I decided to install the rom AUTODROID 1.2! I downloaded the ROM, install the .zip TWRP (latest version) and so I had a bootloop .. Restore backup done previously with TWRP! I am looking online and I see that making the dowgrade from lollipop kitkat, first I had to flash the rom original KitKat!
ADB and fastboot drain, drain the "ROM" (the right one for the Nexus 7 2012 wifi), reboot into fastboot mode and do the command .bat adb .. but something went wrong
"Fastboot.exe stopped working"
From here you have begun problems: recovery is no longer accessible, and restart I always brought to the fastboot mode! I had the bright idea to turn off the tablet ...
From here .. Black screen, fastboot mode is not available, recovery is not available, so I can not even give commands ADB .. When the connection to the tablet pc, windows gives me input connection, but during the driver installation I give me the error "Unknown Device" ..
I do not know what to do .. Can you help?

You could try using the nexus root toolkit ( wugfresh NRT ) to fix your nexus

No OS Installed

Hello, yesterday I was going to update my system and I press system and internal storage delete so I have nothing on my phone and I tried connecting usb to pc and transfer os.zip but its not working..:fingers-crossed:

You can use sideload if you have twrp installed. You must enable mtp in twrp to get a connection.
But i think you should open this in the q&a thread...
More information: https://twrp.me/faq/ADBSideload.html#

i dont think your phone is without an os, they have a particular part of storage for this very reason.. i think you should just do the unbrick process and you should be fine

If your fastboot is working then install fastboot images of oxygen OS

install first qualcomm or oneplus drivers in pc first then only it will detect ur device internal storage in recovery mode then go into recovery connect usb ur internal storage will show there u can put any rom to flash
disable signature verification before installing drivers on window
