hi guys
im not new to flashing but this is the only problem that makes me very nervous
im on v20e by szymel i have cwm 6.0.3.2 and when i tried to install the slimbean i got status 7 error so just rebooted the device to install rom manager to update my cwm recovery but i cant download it just stays at 0% so i cancelled it and downloaded the official recovery image from clockworkmod web site and i installed it thru terminal emulator using this command
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17
i thought it was success becoz i tried to reboot to recovery it boots to recovery but when i saw the version its not updated, then i recall i missed a sumthing on the command, the command should be like this
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17 bs=4096
now my phone is stuck at lg logo cant boot to recovery, didnt try to boot into emergency mode though
ill report if i can boot to emergency mode and flash a kdz

Use the KDZ to get back to square one.
Seems to be the best solution to your problem.

Good to know i wasn't the only one
Im just able to start researching now, i'll update if i find anything, but i assume there's some kind of command that can be given via adb to disable the fastboot and allow the phone os to resume functioning, as my logic indicates since the restore worked for you, your phone is now simply at a point with no attempted update. i did the same process of clicking reboot, twrp looping, restored a backup and twrp still looping
EDIT: Pretty sure it's going to be a flag in a flat file. Combing over my init.rc file now, and i found a strange file called smpl_boot with a single 0 in it, not sure what it does

Can you enter Download Mode? (Holding volume down when G2 is turned off and plug the USB)
I also experienced this when restore using TWRP. But fortunately I can flash back to stock.

I think you dont understand me, when i did restore twrp shows that restore was completed, and when i do a reboot it shows
450 Fastboot mode started
500 udc_started()
Now i cant do nothing with phone, i try to power off and turn on it just go to
450 Fastboot mode started
500 udc_started()

ahh i misread your post thinking you somehow had status messages on your screen during boot and that you got into TWRP each time. the question above this post asking about download mode may help you

specifically:
adb shell

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
fixed it for me for anyone finding this post that CAN get to TWRP, the above linked post has other hints as well that may work for OP
I got this same thing when I tried to update TWRP using flashify, I can reboot to phone , running CleanRom 2.0 but not to recovery in order to flash other stuff.

I somehow managed to do this as well. Did you get yours working again?

My situation is a little different than yours, but you may be able to do this method (which is what I am working on at the moment). As long as you can get into download mode.

Hi, sorry for my english , I'm french
I wanted to flash a custom rom on my LG G2 D802 .
I wanted the Paranoid Android (PA +) with 4.3 JellyBean .
So I made the
Backup
Wipe data / factory reset
Wipe cache partition
Wipe dalvik Cache
After I
Choose zip ( custom ROM ) from sd card
Then I
Reboot System Now
And turn on my laptop, I get an error message saying
[640 ] started Fastboot Mode
[ 690] udc start ()
I realized I had to flash AOSP kernel before changing to a ROM paranoid . But my kernel is blocked and so I have to go back to the stock ROM
When I did this tutorial using lg tools , flashing stops at 49% with an error message .
I also saw that I could access the recovery mod by following this link http://forum.xda-developers.com/show....php?t=2565904(but I saw that I could not otherwise reboot my phone after it was bricking ) and therefore flash my stock Rom which I had made the backup . But I do not know if the ROM has been saved and if it remained in my files after the Wipes.
If it is not there, is that in buying a micro USB ====> HUSB adapter, I could install a stock ROM from a USB key ? Or is there a way I can put files from my computer to my laptop which has no port micro sd?
And is what I could with my kernel "blocked " ?
Thank you very much
Same problem here too. Can't get a recovery installed no matter what i do
Does anyone have a solution yet?? Same thing has happened to me.
If you can't go into download mode but get fastboot mode instead first repair download mode using http://forum.xda-developers.com/showthread.php?t=2477595 and than flash back to stock 4.2.2 using http://forum.xda-developers.com/showthread.php?t=2432476
My G2 can not go into download mode and recover mode, and my computer can not recognise it so I can not put anything to it.
fast boot
udc error.
CAN SOMEBODY
EXPLAIN IN SIMPLE WAY STEP BY STEP.
Thank you
Had this exact error too, fortunately flashing furnace kernel fixed it.
Tahir, I had to try several times until i succeed to boot to my recovery mode, try several times.
was having this issue. but i figured out my problem. the rom i was installing was a note3 rom. hahahaha. thats what happens when u have too many phones. and files in your computer. anyways.
i ddnt have to revert back to stock. i was able to reboot to twrp via hold power button and volume down buttons, when lg pops up, let go and press and hold both buttons again. when white screen with words comes up, press power then power then power. then ur back to twrp, at least mine did. and restored my recent back up.

How did you flash the kernel if you couldn't get into recovery?
I have download mode, but lg support tool only goes to 49% and I get error.
Would like to flash this kernel if you have another way

Try booting to recovery after you charge your phone for at least one hour and while it's NOT CONNECTED to the computer
If that's doesn't help try using ADB
My phone was install flex rom, but I do nandroid backup back to stock still rooted. After update to kitkat on stock rom, the phone automatic reset to twrp recovery. I can't press volume up while plug in usb cable to get into download mode for make factory reset. Is there anyway I can go to download mode from twrp recovery? My phone still keep going boot to twrp even i tried to restore different backups. Help me!!! plz
Usually the update software conflicts with twrp. U are trying to go into download mode? Or trying to boot phone. I think I had to remove twrp before I could receive the update. . please clarify what u are trying to do thanks!!

"If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:"
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
That got me back to a working rooted 4.2.2. After that, download mode and everything else will work.
Hey guys, earlier while trying to switch superuser apps i guess i accidentally unrooted my phone. I was running Resurrection Remix 5.0.2 Rom and had TWRP recovery. The first thing i tried to do was re-root the phone using TowelRoot but i couldn't cause for some reason whenever i entered the app it was completely zoomed in and couldn't move around to click the "make it rain" button so i was like ok since i don't have a backup of this rom ill just restore to the original firmware backup i made before i switched roms, root and then install a clean version of this rom again. I reboot into TWRP and restored the backup only now it just shows the LG logo the plays the AT&T boot animation, screen turns black and it plays the animation again. Over and over.
I tried to get into recovery using the power and volume buttons but it just takes me to the Factory Hard Reset screen. I really don't wanna lose all my files i had on the phone.
Ok so after hours of searching i finally fixed it and thought i'd post here exactly what i did in case somebody is in similar situation. I didn't realize that you could just press the power key on the Factory Hard Reset screen, since it really doesn't reset your phone if you have a custom recovery installed so it just took me to TWRP. Once there i wiped everything except internal then i decided to flash the KK Baseband and Cloudy G2 since i had those saved in internal. I pressed reboot system and it loaded up the LG animation boot screen and then hit another bootloop. So i turned off the phone and went back into TWRP (again i had to hit power twice in the Factory Hard Reset screen for it to actually go into TWRP). This time i found a post to enter some commands in terminal on TWRP: **I was unable to post external links since i am a new user so ill try to post the commands below** then i rebooted and it told me that it appeared i no longer had root and asked me if i wanted to install superuser and i slid the thing for yes, it rebooted and got stuck in a bootloop again. I then went back into TWRP, wiped everything again except for internal. Then i flashed LGD800 10O Radio (I think that's the JB baseband for lollipop to be able to run without a problem) and then flashed CM Resurrection 5.0.2 Rom and gapps. Rebooted and it started up without losing anything saved internal!
On Terminal Command Type this:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit enter
type
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.
I made a mistake and I am hoping to avoid finding a jtag service to help me out.
Phone LG G2 D801 - T-Mobile
OS Android 4.2 factory load
I made a huge mistake, I recently downgraded my OS from lollipop back to jellybean using kdz files. I went to install twrp on this device and found an installer on the google play store called (D801) LG G2 AutoRec-Lollipop. My mistake as I was so used to running lollipop instead of jellybean that I installed this:
Now when I rebooted I currently go into a boot loop and never get past the LG screen. I also can not get into download mode using the volume up key/usb cable combo, it just gives me a LG prompt/boot loop. I can get into twrp (recovery mode) but can not install any custom rom, it fails. I tried running the following commands and they fail saying I have no space available.
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
Since I have little on this device I wiped the data which did not help. I also tried repair permissions and this did not help.
When I plug my phone into my pc I get a drive mapping and can copy files to the /sdcard directory but any zip I put in their I can not install from twrp. The command adb devices gives me no device found. I think this is because I am not in usb developer mode so I do not see how I can side load a new twrp .
At this point I just want a working android on this phone. my goal going into this was to load cm12 but if the stock load is my only option then I will go back to that.

Why not try the flash tool and a kdz install again?
I had an issue with TWRP causing screen burns and no boot.
I turned off my phone by holding power button at least for 10- 15 seconds & then press the volume up & connect USB cable connected to your PC
Flash tool + KDZ = Unbricked Phone.
This should help most people.
I know this response is too slow, but hey I am not tech support
If in in the USA I got my brick fixed for $20 on eBay. I was stuck in the same scenario.
