[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.

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.

system deleted, TWRP ready

Hello,
i delete the System and Data on my LeEco Le Pro3.
TWRP is installed.
Can i flash a rom with an usb flash drive in TWRP or fastboot?
greeting gizez

Boot into TWRP and use MTP to transfer ROM file from your PC to Phone. Then flash the ROM.

I have this problem, but I can't see the phone when connected to a PC. adb sideload doesn't work (adb devices doesn't find anything). Do I need to install driver for the phone? I originally used fastboot to unlock the bootloader and flashed TWRP, then installed LineageOS and gapps just fine. I then proceeded to wipe system in TWRP (I was trying to get back to new phone setup so I can transfer stuff from old phone, which I skipped the first time).
Any idea how to get around this? I tried plugging in pen drive through an micro USB OTG and a usb-c to micro usb adapter, but it's not recognized in TWRP, either. Would very much appreciate any help!

You can get your data. First try to connect phone while is in TWRP. Your phone can be detected as file manager. Try this.
If not, check my theme;

Go Advanced -> ADB Sideload, type "adb sideload aicp_zl1_n-12.1-NIGHTLY-20170516.zip" (zip of OS should be downloaded and put into "Minimal ADB and Fastboot" installation folder with name as same as the text of command). It should let you turn on system.

Also "adb push" command can be helpful. Sometimes phone is not current on adb devices list, but you can also try. As i remember, target should be /sdcard/0

Thanks, but unfortunately no luck. Both adb sideload and adb push said error - device '(null)' not found. It seems like the PC is not recognizing the phone. I checked device manager on the PC, it showed LEX727. I right-click and had it install the driver. It says driver successfully installed. Then device manager showed MTP device with a !. I again tried having driver installed, but this time it doesn't find any driver.
I'm at my wit's end... Any more suggestion?

TWRP and/or Minimal ADB isn't trouble here? Tried you both on main menu of TWRP and in ADB Sideload mode? You can also try do it trough bootloader, for this check my link and read all.

Actually, the problem is solved, by using another PC. This one showed LEX727 in windows explorer as soon as i plug in the phonr (in twrp). I was able to drag and drop the zip files to the phone and go on my merry way. Now back in business!

Meizu MX4 Pro boots into recovery mode "no firmware found"

Hello XDA community, I come to you for help after messing up badly, trying to install cyanogenmod on the Meizu MX4 Pro.
Now the data on the device is fully cleared and it keeps booting into the stock recovery that has only 2 options:
1. System Upgrade - which doesn't do anything since the device doesn't contain an update.zip file
2. Clear data - no point in clearing nothing
(I did root the device when the Flyme OS was installed.)
When I connect my device to my desktop computer, the pc recognizes it but neither "adb devices" nor "fastboot devices" show anything and there is no option to open the internal storage and insert the update.zip file. When checking the device manager. the phone shows up as "LeMobile Android Device" and the driver as "Android ADB Recovery Interface".
Same thing for my Laptop, except it shows up as "Kedacom USB Device" and the driver as "@oem34.inf,%SingleAdbInterface%"

Device bricked

Hi!
I bricked my axon7 g.. I had a running CM15.1 and wanted to restore a CM14.1 backup. First of all i downloaded and flashed the modem and bootloader for cm14.1. after that i wiped system and data and rebootet into recovery. Here I noticed a bug wich i already had when I updated to CM15.1: the data and system partition are unable to mount. So i download and installed a other recovery (nfound) and rebooted. And here is the Problem: I'm unable to go into the recovery.
After some hours of trying different methods I need your help. This is what I found out:
1) I can boot into FFBM and fastboot
2) when I boot into fastboot the windows device manager shwos me Android ADB Device
3) when i try to use the adb tool i says:
Search >>> interface found >>> Android ADB Interface
Checking ADB Interface:
Command execution adb devices >>> !!! Error !!! no answer from phone
This is becuase usb debugging was not enabled.
4) When i use the dfu tool and wnat to confirgure the ports it only says: this device has no usb ports or (when i turn of virus scanner and reboot..) "the tool is running"
Is there any way to flash a recovery?
Thank you!

I solved it via fastboot and adb
