TWRP wont start ADB sideload

Hi folks!
I wanted to install Cyanogenmod as described in Cyanogenmod Wiki.
So I downloaded ioroot, rootet my phone via adb and used AutoRec to install TWRP (version 2.7.0.0).
Then I rebooted into recovery mode, wiped EVERYTHING and wanted to sideload the CM image via adb.
So in TWRP I selected Advanced/ADB Sideload and swipe to start sideload but all that happens is the notification "Starting ADB sideload feature...".
Consequently the phone is not recognized by adb on my PC.
What can I do to make the sideload feature work?
BTW: TWRP tells me that my devices doesnt appear to be rooted when I want to leave TWRP (reboot). Moreover when i want to enter TWRP again (by pressing POWER + VOLUE DOWN) I first get a screen that asks me if want to do a factory hard reset! Only if I agree (by pressing the power key) I get into TWRP.
Contrary when I enter the Download Mode (VOLUME UP when when connecting the powered off phone to the USB port) I am told that the phone is rooted. Moreover the LG Mobile Support Tool is able to detect the device and tells me that the installed software is up to date.
Thx!!

have you tried typing 'adb sideload rom.zip' on a command window on your pc? name the rom, rom.zip, and have it your adb folder.. also type the command from that folder

Make sure you're in the proper folder in prompt and the device name will be sideload if you do, adb devices.

Thanks but this doesnt help either. Same error message "error: device not found"

boot into twrp, don't start sideload
try adb devices, if you get not find you need to change the usb drivers
when you have it working, type, adb push /sdcard/ rom.zip .. check the syntax on that command, but i think that's right from memory

[Q] installed twrp recovery but bootloop with no download mode

After flashing recovery via flashify i get TWRP 2.6.3.3
but when i try to get firmware update mode (download mode) it stucks says: download mode.. and cannot recognize by PC whatsoever, so cannot use lg flash tool or support tool or dp-tool.
and in this mode phone gets really hot!
when i enter recovery i couldnt manage to install any rom because my sdcard is empty and otg-usb is not recognizable.
and in recovery mode, pc cannot detect the device only unknown device as "LG D802"
so i found android adb driver and manuelly install to windows.. but still i cannot pust any file over usb via adb.
adb push command gives me "read only system" error.
i also tried adb sideload to install custom rom from pc..
adb sideload command still gives me "read only file system"
i am assuming this is due to secured Kernel.. but i don't know what to do..
i also try the terminal command in twrp for adb commands.. but still no luck.
what can i do to push any custom rom.zip or any way around to install kdz?

i manually installed usb adv driver.. do i need to install as lg adb device..
can you give me a link to adb "inf" driver file?

Y uninstall current lg driver and download newest driver then reinstall( y can use google to find). Good luck

thanks i solved the problem via ubuntu.
i used "adb push" to /sdcard still got "read only" error.
but when i used "adb push" to /tmp i can managed to send/copy some zip files into my device.

Does fastboot work properly?

Windows 10 Home on host computer, and ADB tools installed.
USB debug mode on and host computer allowed.
USB PTP mode.
LG Unified Driver installed.
I opened command prompt, locate adb platform-tools. Ran the following commands
Code:
adb reboot bootloader.
The phone rebooted to bootloader.
On the bootloader mode on the phone, I typed
Code:
fastboot reboot
The phone rebooted properly
Does it work right?
Currently the phone is not ready to unlock bootloader until there's no problem, especially speaker problem, found.

Windows 10 laptop can't detect softbricked Nexus 4, TWRP, no OS

I've checked other threads but other similar threads were able to get the phone detected in Device Manager so...
I went to factory reset my old Nexus 4 after using it whilst my LG G4 was being repaired. Instead of wiping the data, I accidentally wiped the entire phone, OS included. I wasn't paying attention to what i was doing due to working at the same time and as a result the phone now only boots into TWRP and fastboot mode, but nothing else.
I tried to connect it to my windows 10 laptop so I could flash a new ROM but my laptop can't find the nexus 4 at all. Not when in recovery or when in fastboot.
Opening device manager shows that it is not there at all. There is no ACER usb device driver, nothing that resembles the nexus 4 at all. I've attached an image showing what device manager shows when the nexus 4 is connected and in recovery mode.
As you can see, there are no drivers I can uninstall. I have installed the google USB drivers from Android SDK manager. Still doesn't show. ADB doesn't work either.
I have tried multiple USB cables and every USB port. The phone charges when using an AC adaptor and charges when connected to the laptop. I can't try a different computer because I do not have access to one. Frankly I'm at a loss as to what to do.
When my nexus 4 was previously unable to connect I was able to see the device and just had to uninstall/reinstall/update drivers to get it working. This time, I can't seem to do anything. My LG G4 connects fine and without issue.
Anyone able to help?

The only way to really tell if it is a software or hardware issue would be to try another computer with Win7.
You may be able to flash a custom ROM with a OTG drive as well.

I had the same problem. When using adb and fastboot I get errors about like "error: device '(null)' not found".
Youtube video with id t0pV2pSw2N0 (sorry I am not yet allowed to post external urls) was helpfull and now I can see Android Composite ADB Interface again in the device manager. I still can not use commands adb and fastboot with exception of adb sideload. Unfortunately I have not yet succeeded to flash an image succesfully with sideload.

first try 2 remove any current drivers that are installed.
then u should experiment with different drivers.
the SkipSoft ToolKit have a huge selection, try each one of them (one of them should work).
begin with the ULTIMATE drivers and Adb/Fastboot Installer and if it don't work use the toolkit drivers.

For me it turned out that MTP was enabled by default. After each restart MTP was enabled again. Now I have disabled MTP and my device is found by normal adb command.
Steps:
1) Start your device in twrp recovery mode
2) In main menu go to mount and tap "Disable MTP"
3) In main menu go to advanced -> adb sideload. Wipe caches and slide to start sideload
4) On your pc go to the command shell
5) Start "adb sideload <image_name.zip>" (replace image_name.zip with a valid image). It does not matter whether this fails or succeeds. Only thing important is that adb connects to your device.
6) Start "adb shell getprop persist.sys.usb.config". As result you will see the actual setting of the USB configuration your device when starting up. In my case it responded with "mtp,adb".
7) Start "adb shell setprop persist.sys.usb.config adb" to enable only "adb" configuration
8) Repeat step 6 to check result
9) Restart your device in recovery mode
10) Start "adb devices" to check if your device is now listed.

I tried removing all USB drivers and then using the toolkit and tried installing each driver. None of them allowed my PC to detect the nexus 4. As you can see in the attachment, nothing in device manager remotely resembling my nexus 4. This is after uninstalling and reinstalling and also updateing the LG G4 drivers (it makes no difference).

Unfortunately I don't have access to any other PC for this purpose. I can't connect download software or connect USB devices to the PCs at work due to security. I tried an OTG drive but TWRP wouldn't let me mount it, apparently OTG is not enabled by default for the nexus 4.
I've tried all 3 USB ports, several different cables but no luck. I guess that's it for this nexus 4 then?

If the phone is not booted into its ROM, ADB commands won't work. You need to use "fastboot devices" with the phone in bootloader mode.

You android device will reboot in several different boot modes (fastboot, recovery, normal). For each of these boot modes a separate device drive might be installed on your Windows. So check the device drive after each change of boot mode. If needed uninstall and reinstall the correct device driver.

Fastboot doesn't detect my phone, please help

I want to install LineageOS so I closely followed the fastboot and adb instructions on the official site. During my first (failed) attempt, there were some old Google USB and ADB things on my PC, so I deleted everything and started again with a clean slate.
I managed to make ADB work (adb devices detects my device, could authenticate the computer, all seems good there). But if I start the phone in fastboot mode, connect and run fastboot devices, I get nothing back. It doesn't give any sign of the connected device. Windows's "Devices" window lists a device called "Android", but it's under "Unspecified" and has the yellow triangle/exclamation mark on the icon.
1. Am I right to assume that this will stop me from unlocking the bootloader (if I will use the unofficial method) and flashing TWRP and a custom ROM on the device?
2. More importantly: What could be wrong, how can I make fastboot see my phone?
Many thanks for the suggestions!

hi,
first do you have latest ADB and Fastboot
then connect your device and run adb devices. check if it detect the device means from the command prompt run "adb reboot bootloader" (without quotes)
now once after device reboots to bootloader check fastboot devices it will detect now
if not then goto device manager,right click on the device and click on update driver software and choose android fastboot interface
you are done now run fatboot devices,it will detect the device

Solved!
