[Q] EMERGENCY: Recovery doesn't mount USB! - Nexus 4 Q&A, Help & Troubleshooting

Hello,
after trying out a few roms i wanted to go back to stock and wanted to have a completely clean device.
So i went booted to TWRP recovery and wiped everything i could (including the currently installed ROM and internal storage).
So I wanted to mount USB to copy the ROM on my device but it doesn't connect to the PC.
So I'm stuck in recovery and have no idea how to connect it.
I hear the sound of the PC recognizing a USB connection but then comes that USB error sound you hear when it fails to connect.
Please help

Of course it doesn't. Internal storage is not UMS.
Use adb to push files.
Also, if you want to go back to stock you don't use recovery. Use the bootloader and fastboot.

Can you please explain why UMS had been disabled on custom ROMs? It was so easy to transfer data to memory using UMS!

I did try to push via adb but as I said the USB didn't connect
but thanks I did go back to the thread u posted and noticed there are two links for the drivers
it seems that the 2nd one (it's the one I had installed) doesn't actually include adb drivers so my device couldn't connect
well so I installed the drivers from the first link and it's resolved thanks a lot!

Well I have gone and done it now... …..

Downloaded cm11 went to flash it and it failed. I have no other Roms on my phone. I'm in recovery right now and every time I go to reset the phone it just comes back to recovery. My question is how do I load a ROM on to the phone while in recovery? At this point I give up and just want to go back to cm 4.3....:\

U could use adb and push it to your phone but I have had no luck in trying to set up adb. IG I were u I would use recovery yo shut down yo save battery and search the development thread if I remember right and download the lg flash tool and stock firmware hold down all 3 keys while plugging in USB and follow the onstructions

Should be able to plug your phone into a PC and mount storage like a flash drive. Copy ROM to storage from PC.

I had the same issue and I installed minimal adb and fastboot to desktop and also installed pdanet for drivers and then used sideload to push Rom to phone. Stock lg drivers in pc don't recognize phone in recovery so used pdanet to install lg drivers and all worked well.

Do you have a step by step process for that?
1. Download and install minimal adb and fastboot in ur pc.(make sure to install it in desktop for easy access)
2. Download and install pdanet.
3. Download paranoid 4.3 and gapps. Rename them to 1.zip and 2.zip for easy reference. Copy these zips to step 1 folder.( does not have to be 4.3 Rom I just referred it as it is small in size and sideload sometimes has problems to push larger files.)
4. Reboot phone to recovery and perform factory reset followed by all wipes in advanced tab.
5. Go to advanced in home page of twrp and start sideload(connect usb to pc) and open step 1 folder and hold shift and right click mouse within the folder window and select command prompt and command opens and it should display in which folder it is opened in. Type adb devices and it should show your phone and if it does not close command.(keep phone connected to pc and in sideload mode) if it does detect as sideload go to step 8.
6. Open pdanet which u installed and go through options to install lg drivers and now your pc should detect your phone.
7. Exit sideload in phone and restart sideload again. Then do step 5 again. Your PC should show and sideload under devices.
8. Google how to use adb sideload as I don't remember the commands it's not hard at all. Once you knew commands push Rom first to phone followed by gapps (it
PS I am not a developer and had to learn these and don't remember sideload commands but it worked for me.

I'll try when I get home. I just went out to try and get a otg cable and is not recognizing the thumb drive.
lingarajug you saved my life dude lol. might not have been a big thing to some of the better informed guys on here but i was freaking out. lol
Glad it helped you, which Rom did you end up flashing, my thoughts is lg g2 is still very new so stay patiently for at least 6 months until more development and support develops for our devices I am staying out of flashing business for the next 6 month's.

Cm10.2 is very very stable. That's what I flashed back to. What's funny is I went to about three local "android gurus" on Craig's list and none of them could fix it. This board is valuable as hell
Yes these forums tell everything but you have to take time to search entire forum. Glad that ur phone is up and running smooth, have fun with ur great lg g2.

Nexus 4 No OS Installed TWRP

Guys I need your help.
I have Nexus 4 16GB pre owned. Bought it with Cyanogenmod 10.2 installed already and rooted. Then CM11 nightlies came and I installed it OTA but it seems that it has a lot of bugs so I rolled back to CM10. When I rolled back and rebooted, it does not come up (Google and Cyanogenmod logo only). I rebooted it to bootload mode, then recovery (TWRP) and accidentally wiped out everything including ROM/OS. I don't have that much knowledge in restoring my phone. I tried connecting it to PC (WinXP) and it does not recognize the device. Tried everything posted in different forums on how to connect my device to PC but to no avail. Cannot do USB debugging thing 'cause I can only utilize device's recovery mode (TWRP). I'm thinking now on having this device repaired by cellphone repair shop just to install OS.Anyone can help? Other forums look like too technical for me. Noob here, really.
Hi I've just had a quick look, try this
http://forum.xda-developers.com/showthread.php?t=2010312
It mentions about installing drivers and says the USB Debugging ones are not required.

Boot up holding vol down so you are at the android part.
Then attached your phone to your PC and use adb push to push a custom rom or download your source image from google.
Grab the google factory image here https://dl.google.com/dl/android/aosp/occam-krt16s-factory-2006f418.tgz
Then do adb shell
mkdir /sdcard/Download
exit
adb push /donwload folder/name of the zip /sdcard/Download
Then go to recovery twrp and install the zip
Should get you up and running

No OS, using TWRP help?

So, short of it is I installed TWRP using freegee, which worked correctly. I had a rom on my storage, and did a wipe twice, but now the rom I had on the SD isn't there anymore and not sure what I should do. I search to figure out how to mount or side load the rom on the SD again, but not sure. Any ideas?
My last resort is to go to Best Buy where I bought the phone the other day and just say my phone is stuck on the LG logo and not sure why, it is possible to swap out phones, and hope they let me?
If I get an OTG UBS cable, and put the file on a external USB or USB sd card reader, will that work?

Did you not create a backup before flashing?
Backup was deleted too, or else I would have used it.
Ok since you mess up ! And dont know how to use adb. I suggest you use LG Flash Tool to go back to factory stock so you can go back to stock. And Noooooo returning the phone when it's rooted won't work you have alvery void your warranty by doing that they won't take the phone like that since they can just check if the phone was being rooted and there is no way right now to remove the counter.

Well I tried to ADB via adb sideload, but it didn't work? It said it was starting sideload features, but nothing happens. I tired to use ADB push, but the device was not recognized. Any suggestions there?
So, is there a link to using the LG Flash tool? Thanks
Did you set up adb in the computer? Do you have the drivers for it? If yes check the cable or the computer usb port is the problem.

Here ya go buddy.. This is the easiest way.. Flashtool
http://forum.xda-developers.com/showthread.php?t=2432476
Well I would think ADB flash tool should work if I was able to root via command prompt. I know I had the drivers installed. I will try a different usb cable, and usb port. On a side note if I get an OTG cable and use a SD card with a usb reader will I be able to use that to just flash a rom?
With adb, I click adb sideload, and then let in starting sideload features mode in the fastboot folder I open command prompt and type adb push rom.zip with rom.zip being the new rom i want to install, right? But, when I tried that nothing really happens.
This one is specific for Verizon, if you have the Verizon model since you never specified. Try this or the other one posted. And also read up a little more you seem a tad on the short end lol ? http://forum.xda-developers.com/showthread.php?t=2448960
Yeah that is the one I am reading as I have the Verizon model. And short end how so?
It worked correctly and I feel relieved. Thank you all. I just re-rooted and installed CWM touch via command prompt and it all worked correctly. Now I am just waiting to download another rom and see how that turns out. Again Thank you all.

[Q] broken N4

phone got wiped, os and all. can only get into team win recovery (no android with !). in recovery file manager there is NOTHING on the phone. can not get phone to be recognized by computer. used sdk to install drivers still nothing. can not activate usb debugging as there is no os. reboot in recovery gives warning no os on phone. there is nothing to restore, all folders in install tab are completely empty. is there anyway to save my phone? there is nothing on it...just enough for safe mode and recovery.
You need to get the computer to recognize your device. When booted into recovery and the device connected to your pc go to device manager and see what the issue is.

You've got two options
1. Flash the factory image.with fastboot. You'll then have to re-install twrp amrd root
2. Push a rom onto your device using adb in recovery. Then flash that in twrp

ok...it is recognized in fast boot but not in recovery. as far as i knew i only need the usb drivers that come from sdk as it is a google device. is there another driver set i need from recovery. where could i find super simple instructions of how to flash image? and if i didnt care about re rooting could i just use fast boot to flash iamge and run with that?

Simplest way is to download the factory image. Google nexus factory image. It's a .tgz file. Extract it using 7-zip. There's a flash-all.bat file in there. Boot into the bootloader and with your device connected to the pc just double click the flash-all.bat. It will wipe your device so if you can, backup first.
