Hello,
I just got my Hero this weekend and I was interested in partitioning the SD Card. I have been following a guide and when I boot into recovery(Screen that shows phone with triangle and exclamation point) the computer does not seem to see the Hero anymore.
When I plug the phone in while it is running Android the computer picks it up fine in Device manager. Once I type adb shell reboot recovery it boots into the screen the computer no longer picks it up. I have tried unplugging and replugging the USB cable while in the recovery screen but still get nothing. If I type adb devices before I run the recovery command I am able to get the serial number, once it boots into the recovery screen it no longer shows me the serial number when I type in adb devices. But this is due to it no longer being picked up once in the recovery screen.
I'm not really sure what I am doing wrong here. Can anyone help me get this issue sorted out?
I have tried it on Windows 7 and read that a lot of people had issues with the syncing so I just finished attempting it on an Windows XP machine and still get the same issue.
One more thing, when in the recovery screen the phone does not respond to the power button anymore. It seems almost like it locks up or something. The only way I can get back out of the screen is by taking the battery out and putting it back in. Is this normal?
Any help would be really appreciated!
Thank you,
Mizex
You need to root the phone and install the recovery partition first.

Exactly what jonnythan said. If your recovery screen shows the triangle then you haven't installed a modified recovery image yet. Follow any of the guides on this site for rooting.
Oh wow I feel dumb the guide I was following said nothing about the phone needing to be rooted. I attempted to follow a 1 click root and while attempting to do the backup step I get a message saying that it can't complete the command. According to the guide if I get this error then it means I have a patched firmware and need to downgrade to a cupcake firmware.
Anyone know of a good guide for doing the downgrade? Or can perhaps share a bit of knowledge on the error?
Rooted my LG G2 (ATT) recently. Yesterday i got an error on bootup stating that system UI has crashed.. After that all hell broke loose. Phone when powered on only boots into the TWRP, friend thought he could "fix" the issue by doing a format on the device.. FML. SO now when trying to get into download mode to perform the Stock Rom/Unbrick process it just won't allow me to do anything. It just keeps booting into TWRP.
My laptop has all drivers needed, but phone won't be detected by my laptop..
Anyway how i can get my LG back to stock & working? Didn't have a custom rom or anything, only the Camera Mod which never gave issues..
The system UI came on before i did the Camera Mod by the way..

Holding volume up & plugging in usb cable boots into TWRP.. Holding both vol down & up, while plugging in USB makes device stick on LG logo screen..
Hehe i have same Problem
Flash a Rom
start at the recovery, go to Advanced, then Terminal Command, press Select,use this code,
dd if=/dev/Zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Then reboot,this works.

Copy a Rom on a USB stick and install it in TWRP via OTG, run back into TWRP and enter this line
start at the recovery, go to Advanced, then Terminal Command, press Select,use this code,
dd if=/dev/Zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
That should solve your problem, for me it just works
Only in this way can be turned off Trwp as default and the phone boots normally
Good Luck!

Have you tried to use the "sideload" option to see if you can load a rom onto it yet? This requires that your computer sees your phone with the correct drivers and adb working too.
Did you try to do a complete wipe/reboot and see if you can get into download mode?
If none of those methods work then I'm not sure what to tell you. I ran into two problems only so far.
First one was when I accidently wiped everything and had to sideload a rom onto my phone.
Second, I took the OTA update and had the bootloop TWRP problem which was solved by using the LG Flash tool to flash the stock Sprint rom onto my phone by following the directions for the Verizon Method but used a Sprint rom and dll file.
If you can't sideload a rom or get into download mode then you have a major problem there but it could be just that you've overlooked something.

Copy a Rom to Usb and install the Rom via Usb/Otg Cable,it is self to install from internal Storage.You can Select OTG or internal Storage in Recovery to install the Rom.Its easy,I can Backup or install Roms on Otg.
Sorry for my Bad English,i hope you understand me!

nope doesn't work.. Won't connect to PC... It did before fine.. Sideload is stuck at loading screen or something. I'll try loading rom onto USB & from usb to phone once i get an adapter for USB Female to Micro USB.
He got out.
I was stuck in the bootloop for about 6 hours before I realized I had the correct dll, and tot file, the correct utility from LGE, and I turned the noodle of a brick into a "unbranded" phone temporarily, until sprint came to the rescue, and branded everything back from the production image I loaded just earlier. I just wanna say this... DO NOT PLAY WITH PHONE DIALER CODES MEANT FOR THE KOREANS WHO TEST YOUR PHONE!!!
You can brick that **** fast as hell. TWRP kept coming in, and I didn't know how to deal with adb sideload, or the basic dd command to get things back to download mode. Now I have a real working knowledge of recovering from an otherwise hopeless state. Take your time, and explore slowly.
Your mileage may vary, just sayin'

I experienced this situation for a while.
The solution is doing a normal procedure to install custom rom from USB.
Just copy custom rom to USB, choose advanced wipe, then wipe dalvik, cache, data, and system. Then install custom rom in USB, and, reboot phone after installation finished.
Phone should be back to normal again.

***i try second one but i jusy says:dd: can't open '/dev/block/platform/msm_sdcc.1/by-name/fota': No such file or directory. :crying: ***
I have the lg g2 from at&t and yesterday i went from cm10.2 back to the stock backup i had for the g2 and received the OTA update. I didnt think much of it and downloaded it, now i am stuck on the endless loop ending in the TWRP screen, I have about 3 back ups but every time i try to restore it it just ends up back in the recovery screen. I've tried to do what i've found on the forum as far as using terminal command from twrp , but all i get is a list of folders, i tried using adb but because of the phone being in it's current state the drivers wont install correctly on the computer, so it doesnt register. Pretty stuck right now and dont know what else to try or do , any help will be appreciated. thank you
Look this
forum.xda-developers.com/showthread.php?t=2451696
I cant do that method because option 1 , adb cant communicate with my phone due to the drivers not being able to install correctly and i tried option 2 but i dont see where to enter the command in terminal command , all i see is a directory of folders
In Twrp,go in Terminal and Press Select
Write this line:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
And go - finish
Here again accurately described
dd[space]if=/dev/zero[space]of=/dev/block/platform/msm_sdcc.1/by-name/fota
[Space] stands for space bar
I can't thank you enough for taking the time to help me out with this, thank you and forgive my ignorance with the whole terminal thing i am still new at all of this .
The LG G2 is rooted then I got an update on my phone that asked me if I want to do it and then I accidently did that.
What happend I'm stuck in Teamwin recovery with no rom and no backup and nothing left on the phone everything is erased.
When I try to do a the button thing with volume down and power button I get in to some reset but that won't work as well.
I hope someone have had the same problem or have a solution for it. Please guys help me if no one can help me with that I have to ask you if it's possible to send it to a certified LG workshop and get it fixed thru the warranty.

ok if you have adb access on the pc then try the following commands(if you don't know what this is then skip this part)-
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
if you have twrp 2.6.3.3 or later than go to the terminal app inside twrp and type the following-
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
if that one doesn't work you can aso try-
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
and if the above does not work then you are going to have to flash back to stock using the following guide http://forum.xda-developers.com/showthread.php?t=2432476
If you can get in to TWRP, you should be able to plug in and send a rom to it over USB (I think TWRP has this ability, but I have not used it). Alternatively you could use ADB to push some files to it also. Anywhos, once you have a rom it sounds like you should be able to flash away and be good to go unless I missed something in your OP
I've tried everything and it won´t work. I need to know how to send a rom in to a phone thru usb, but I have another problem the computer recognize a product "g2" but when I plugg it in I can't find it, the drivers that I installed can't find it as well. Please somebody help
I was a complete idiot and accidentally deleted the internal storage on my G Pad 7.0 v410. I can still boot into TWRP. I've tried flashing stock and Skinny ROM. They are successful according to TWRP, but I cannot boot into anything besides TWRP.
All attempts to sideload in ADB have failed. All attempts to factory reset or wipe dalvik multiple times worked, but did not help. I am currently at a loss for what to do next.
Fixed finally!!!
this took me hours of searching plase hit thanks
1. if you dont have adb setup adb you can get a minimal adb here
https://docs.google.com/file/d/0B1S0LCuXCnnmSWh6NGJmSE1BUWc/edit
install it, navigate to program files (Or if your on a 64bit system program files(x86)
Right click and click "Open command window here"
plug in your device if it isnt already pluged in, and type the following commands pressing ENTER after each line
DO NOT COPY PASTE THE WHOLE THING EACH LINE MUST BE PRESSED ENTERED separately
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
exit
adb reboot
Your phone should boot into your rom now

I tried this but it didn't work. I tried adb sideload and directly used the commands in twrp's terminal command.
Worked like a charm
This saved me! I am not sure what I did wrong but this did the trick. Thanks a million for sharing!!!!
Holy crap i love you!!! My tablet decided it wanted to do a system update while i was sleeping after i told it not to. Long story short the commands worked!! and i have a working device now!

Boot : Error Certification Verify
Hi. I am new to this thread although i had used this thread many times with issues i have had. There is this one issue im having that i can't seem to figure out which im usually good at doing by following forums or threads.
A couple weeks ago i had rooted my LG G Pad 7.0 V410 LTE tablet from AT&T. I had TWRP downloaded into it and i had flashed Candy5 it worked perfectly i just didn't like how it looked so i tryed to flash it back to original stock OS. But now when i boot my tablet up it goes to the LG screen and at the top left it says Boot : Error Certification Error. This has me dumbfounded on what i should do. when i connect the tablet to the computer nothing pops up no tablet connects to the computer. I tryed downloading the drivers and everything but nothing seemed to work. I need help with this issue please!!
I didn't know where else to post this issue due to being new!!!
This worked for me, THANK YOU, however, I thought I would try to flash the LG Lollipop update to the device, it downloads, but when I go to install it, it reboots straight back into TWRP. How can I replace TWRP with the factory recovery and unroot the damn thing??

As a general rule, when you can't access recovery, or you need to go back to stock etc etc you have to go into DOWNLOAD MODE and use an official or unofficial tool to go back to stock. It will remove twrp root etc etc but at least you'll have a working device and you can start rooting again.
This is a guide for the 8.3 but it should work on yours.
To put your device in download mode turn it off, press and keep pressing vol+, then connect the cable. If the official tool isn't working, you can use lgflashtool 2014 and follow this guide (the only difference should be that the official tool download the factory image from the internet while the unofficial one let you use an already downloaded one. If you use the unofficial version, be sure to download the CORRECT firmware for your tablet. I don't know if at&t require a special version, look it up.
Having read this thread and trying everything here plus other things, I still have a bricked LG V410.
I'm using Linux. Doing lsusb shows the device, but thats about as far as it goes.
from lsusb: Bus 001 Device 012: ID 1004:61f1 LG Electronics, Inc.
from adb devices: List of devices attached
from mtp-detect: libmtp version: 1.1.8
Listing raw device(s)
Device 0 (VID=1004 and PID=61f1) is a LG Electronics Inc. Android phone (ID1).
Found 1 device(s):
LG Electronics Inc.: Android phone (ID1) (1004:61f1) @ bus 1, dev 12
Attempting to connect device(s)
PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt
Unable to open raw device 0
OK.
So, it appears as though Linux can see the device, but that's about it. Interestingly, if I put the device into Download mode (holding down the Up Vol while plugging in the USB cable), Linux will not see the device.
I can also put it into Factory Reset mode using the combination of keys, but that just get it stuck at Factory Resetting on the screen. I've even left it like that overnight and it's still sitting like that the next day.
I'm open to any ideas you folks may have.
I have to backtrack a tad. Putting the device in Download mode, Linux DOES see the device in lsusb.
Bus 001 Device 013: ID 1004:633e LG Electronics, Inc.
and MTP-detect:
libmtp version: 1.1.8
Listing raw device(s)
Device 0 (VID=1004 and PID=633e) is UNKNOWN.
Please report this VID/PID and the device model to the libmtp development team
Found 1 device(s):

PTP_ERROR_IO: failed to open session, trying again after resetting USB interface
LIBMTP libusb: Attempt to reset device
LIBMTP PANIC: failed to open session on second attempt

OK.
Nothing showing in adb-detect.
dmesg shows:
