I have a bit of an issue here. I rooted an installed twrp using this method here:http://forum.xda-developers.com/tmob...using-t3382631
I got everything wotking and then I precced to download the two parts of this rom here: http://forum.xda-developers.com/tmobile-lg-v10/development/rom-v10h901v20estock-customized-t3360240
The discalimer said to not flash 20e if you had already flashed 20j but I assumed I hadnt done any of that ebcause I had just rooted using teh method above. the two files I installed were "V10_H901_V20E_Stock_MM_P1_20160417" and "V10_V20E_Custom_Stock_1e-signed" because I thought those two were the correct ones to install. I installed them in Twrp and now my phone wont turn on. Am I bricked and if so how do I get out of it? My phone wont turn on and is unresponsive to charging ( i was low battery when I installed so it could just be dead) . Any help is greatly appreciated
Can you get into download mode by holding volume+ and plugging the phone into your computer? If so, then you should be able to save the device.

So I rooted my sister's optimus v about a month ago. Today she installed a battery mod app from applanet and as soon as she chose which battery mod she wanted she had to restart her phone for the changes to be applied, but when rebooting the phone it would only get stuck in reboot. So I tried to start it up in recovery and got the blue screen that says fastboot mode started. I looked that up online and found a fix to it but I need it to go into emergency mode to fix it that way and it will not go into emergency mode, any combination of keys only takes it to either the blue screen with the fastboot mode message or it just reboots and gets stuck. So now what do I do? I really need to find a way to fix her phone. Thanks in advance to anyone who tries to help.
try to turn on the phone & use LGMobile update tool. That should recognise the phone & install original lg fw

I managed to finally get the phone into emergency mode. I had installed the LG mobile support tool and installed all the drivers and tried to go that route but it kept telling me I only had one of four drivers installed, even though I have installed several drivers. After all of that I had finally got it into emergency mode so I went back to trying KDZ. I'm supposed to select the rom where it asks for the KDZ file right? But when I go to browse for the rom file it doesn't show up in the folder I put it in. I've rooted 4 phones and have done so many other things with them and never bricked one, was always able to figure out everything I did and never had to ask any questions but I can't figure this out to save my life and it is driving me crazy. I do really appreciate you guys for the suggestions and thanks to your suggestions I have gotten this far.
Hey, I have the same problem. I rooted my phone then I installed that battery mod app on applanet. I installed it then when I had to restart my phone for it to apply it just got stuck and kept looping the reboot screen where it says "ANDROID". Did you get ur fixed yet?

I'm having the same issue right now, although at least you have managed to get it into emergency mode. How did you do it?
The other issue I'm seeing is that there is no .kdz for the Optimus V LGVM670. I found a .cab file that is supposed to be the newest update, but not even sure that will work with the the kdz manager.
It was my sister's phone and I had the same problem with kdz. Had the cab file so couldn't use it with kdz. My sister left her phone with me for a few days to try to fix it and when I couldn't she took it home and managed to fully brick it to where it would do nothing at all so she had to get a new phone. I got it into emergency mode by holding down the volume and it was either the back button or the home button I pushed at the same time, can't remember which. As I held those down I plugged in the USB cord that was connected to my laptop and it went right into emergency mode. Just make sure you disable that LG modem in the device manager on the computer before doing anything because my sister forgot to do that and that is how she fully bricked her phone. Good luck to you guys and if anyone figures out how to fix it I would be interested in knowing how you did it.

hmmmmm, I don't remember completely how I did it, but there was a very helpful guide floating around XDA. I bricked my Mom's Optimus one as well . I actually had to go to the LG support site, type in my Phone serial number and find a list of all the firmware available. From there I right clicked the page and got the page source. From there I got my firmware and I entered it in the KAZ or LG B2I Agent ? - Dont quite remember. Anyways, it ended up working out for me, but I accidentally flashed the German firmware, but in the end, everything was all good LOOL.
I recently tried to install a new ROM on my phone.
I installed it using ROM Manager, which I realize now is probably what caused it mess up. I hadn't checked these forums in a while and didn't realize it was causing issues, so that was my stupidity but what's done is done.
Anyways, after installing the ROM, it just sat on the boot animation endlessly.
I attempted to get into Recovery mode, but when I tried using Volume Up+Down+Power, it always went to download mode, whether it was plugged in or not.
I tried flashing it back to stock image and kernel using this guide but even after that, it still got stuck on the boot animation.
Any help is greatly appreciated.
In desperate cases I found myself in, I have had great success with the the jig method without the jig (for lack of a better term). Look around on the Captivate forum there is a description there. It works like the normal procedure for getting the phone in download mode but then you also (at the same time) insert the battery. I think that simulates what the jig does.
It is awkward to coordinate all the different movements but it works on the Captivate, and I believe I have been successful on the I-777 as well with the same method.

Thanks, I actually did get it to go into recovery this morning. I let the battery drain over night and afterwards, it got into recovery. I'm still having some problems with a few other things but I think all the problems I have now are solvable, although if I get back into the same situation again, I'll be sure to take a look at that method.
try flashing stock pda with odin.
problem solved
I really hope someone can help. I have had my HTC One about a month, unlocked the bootloader, rooted it, installed TWRP, made a nandroid backup, and flashed Android Revolution HD 11. I recently dirty flashed the newest ARHD, 12.1, and since then I can only charge my phone if it is powered off, and then only if fast boot mode is turned off. I tried to flash to my nandroid, but the file seems to be corrupted. I flashed back to my ARHD 11 backup, and that worked but I still cannot charge while the phone is on. I am currently downloading a nandroid from here:
http://forum.xda-developers.com/showthread.php?p=39588860
I'm going to try to flash this and see if it works. Until then, does anybody have any ideas on what the problem is? Also, can somebody provide a link to a walkthrough on getting this phone back to complete stock (unrooted, locked bootloader, etc) in case I need to return it? Thanks in advance...
EDIT: I just found a link to this video which I'm going to try also if the nandroid doesn't work: https://www.youtube.com/watch?v=n_KBYx0xuAs&feature=youtube_gdata_player
Phone won't connect to PC either...
So the video I linked to didn't work because my computer won't recognize the phone. I tried reinstalling the HTC drivers, and still nothing. I also found this seemingly great tool:
http://forum.xda-developers.com/showthread.php?t=2242635
...which didn't work for me because of the problem of my computer not recognizing my phone. I really hope there is either a fix for this issue, or a way to lock the bootloader again without connecting it to a computer so that I can return this phone and get a new one...
Bump for help...
My Lg G5 (Tmobile) keeps on rebooting to recovery mode (TWRP) no matter what rom I flash. I tried using LG Up software but no matter how many times I install the driver phone is not recognized. Firstly I flashed Fulmics ROM then I installed LineageOS (Cyanogenmod) after that phone was working fine for a while till I saw an update and tried updating it to new nightly version. Please help me out if anyone knows how can I fix this issue.
You probably need to put the phone in download mode and then try LG up otherwise try pushing a rom that works through adb

I am sure this method would fix it but I already returned my phone and got new one as I had 1 year warranty. I bought it from T-mobile and I locked the bootloader before turning in the phone so it doesn't look like I was trying anything fishy. Now instead of phone going to twrp each time it goes to boolop saying "device is currupted and won't boot". It won't go to recovery mode no matter what I do and hope I don't get charged from T-mobile saying this and that.
However, I am really grateful to all of you great people who tried their best to help and you sir actually threw me a solution but I was too impatient to wait for it. I know this method will work no matter what as I had been using this tool for my G2 in old days and fixed the worse bricks where I had to openup the whole phone take battery out and stuffs like this. I was looking for this method found everything but LG tool asked me for .dll file which I couldn't find anywhere and decided to give up on it...
Thank you for your help and now I know I am not going to be bricked anymore as I have this method to work with in future issues and am her waiting badly for Xposed to be available for Nougat.

Good to hear that, You are welcome,
And as you mentioned about "device is corrupted and won't boot", that's because you locked bootloader. And as you were using twrp which means modified system partition so phone said that. But you can still go to download mode and use the method to make it live or can try unlocking bootloader to start twrp.
I experienced similar situation. I thought I had to send my phone for repair. As I was able to put the phone to download mode, I used uppercut with downloaded kdz file from LG G5 development thread and restored my phone. I didn't use my phone for four days thinking that I had to take to a phone shop or send to service center. But after careful reading of unbrick tutorials, I brought my phone back to life. Now I can play flashing anything as I am confident that I can easily unbrick my phone.

A few days ago I got my G5 H830 and came with version 6.0.1 h83010i, looking for information on how to install custom rom, I read the post to install the .TOT file to be able to install TWRP and through this the Custom Rom, until there is Everything okay, I did everything right, but then I decided to go back to the Rom stock, on the night of that same day I saw that when I reboot my cell phone it stuck on the LG logo and it had some color pixels damaged (but no screen Damaged, if not because of small brick) then force a restart and continued the same, I did factory reset by stock recovery and then normal start, I went to sleep leaving it in 100% battery, and when I wake up in the morning the cell phone It is off, when I turn it on 5% and I get scared, then I wanted to go back to custom rom to leave those problems behind, but then when I install the TOT again and install the custom ROM it will restart half installed and any rom that installed it would stay Stuck and the LG logo and a bootloop until when it was flash the kdz several times until the cell did not want to ignite more, the pc does not recognize it or anything, I need help with this.
Hello guys and gals, so i just recieved my LG V10 H901 and tried to follow https://forum.xda-developers.com/tm...step-step-guide-rooting-lg-v10-using-t3382631 this guide, but eventually i ended up with a brick after trying to flash the .tot file.
I keep getting
Boot Verification Fail
- cause: MISHMATCH_SIG_LEN
The TWRP recovery i had is now gone, and i can't access Bootloader. I can enter Download though. I read a lot of things around the problem, but i always stuck on various software versions or phone versions i can't really understand. Is there any way to get the phone back working? Before i try any method i just want to be sure i wont mess even worse (if that is even possible).
I tried UnbrickMe thread, but it says only for soft version:h90120j I have soft version H90120c (i haven't performed the update to MM) so i don't wanna try without being sure its going to work.
I m leaving for vacations in couple of days and i don't have a phone :/ please give me your lights.
Also LGUP wont see the phone, the same for ADB.
OK I Fixed it!
I was able to get out of this maelstrom of bootloops and to finaly flash the default ROM (you can find it here https://forum.xda-developers.com/tmobile-lg-v10/general/stock-h90120j000712-kdz-t3436249 )
So what i did is to remove battery for 10 seconds
Put The battery in
Hold volume up button
Plugin the phone to my PC through USB
Then download mode will start
I opened LGUP and fortunately it was able to see my phone.
Then went to Upgrade and flashed the kdz file.
All went smoothly and the phone is back working.
