Ok i was in recovery mode and i had planned on installing a ROM called Megatron(makes cpu faster). I had a bad signal on my computer so i decided to hold off on downloading the ROM. However, i remember downloading a theme and i saw the update.zip file on my desktop. I copied it to the root of my sdcard and on my phone it read,"update.zip.zip"(didnt really bother me because i figured it was STILL considered a .zip file). Anyway, I flashed it from the sdcard and i tried to reboot my phone and it went normal until it got to the Android logo. It would have the sleek light going across the logo but then it would freeze, go blank, then come back and do the same thing again. Now i tried to backup my phone before doing this but when i tried, it wouldnt let me and it told me to do it from the adb(I dont know how). Its obvious im new to this. I dont think its bricked because it turns on and i really dont know if i voided the warranty on it or not. PLEASE HELP ME!
You're bootlooping. I'm not very advanced in all this just yet, but after reading through different forums you gotta flash a factory rom.

If that doesnt work, find a .zip file of the original firmware and flash it through recovery.
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 have an Lg Optimus G AT&T. So i had it rooted and i wanted to unroot it so i downloaded an app from the play store like it said to and i did it. So i restored my phone and the boot logo i applied is still there. I cant get my phone to re root even though i go through all the steps and re try it gives me this ( Screen Shot)... itll say choose restore my phone and when i do itll act like its doing it but then itll just stop. I need help because i may need to send my phone back for repairs NEED HELP!!!!!!!!!!
go into irc chat and use LGNPST to bring it back to stock.
Hello,
I have a Asus zenfone 6 however my problem also occurs on the zenfone 5 phones.
The poblem is as follows,
After updating from stock to latest android (v1,18 at the time) the phones battery display became incorrect making the Phone unreliable at bestand nothing seems to help fixing the problem.
I have tried a million calibratnig apps with zero success as suspect the phones software doesnt actualy understand that it has a 3230 mah battery.
I have found and compared files with a working zenfone6 where the file displays 2070mah for me and 3230 for the working Phone.
I then tried to manualy change this file had no acces even with root but every reboot or unplug it just resets the file anyway as it gets its data elsewhere.
I have tried a factory reset but not everything was actualy reset it just deleted my data but roo and all othr crap that the update screwed up was still there.
I tried ADB sideload but that didnt work and udupdates as ota so will not factory reset and remove root anyway.
I contaced asus but they are as clueless as a goats rear and just say a future update will adress it...Which we al know isnt going
to happen as this has bin a issue for some users for over half a year and they didnt fix it.
So as a final attempt to fix this Phone im planning on unlocking the botloader which i really didnt want to do as im new to all that and just want a rooted stock rom...
So to my question.
If i unlock the bootloader i know the Phone will be wiped. Will i just be able to flash any version of the stock rom via ADB or is there other things i need to do to either the Phone or the rom?
I cant go screw up my Phone without knowing how to fix and flash it again directly.
And do apps like the one asus provide usualy also allow relocking of he bootloader again after flashing the rom as i dont want to leave it open if there is no need to?
Any other ideas are welcome aswell but i have bin trying to solve this for over a month.
Heres a screenshot of the error i get when i try to reflash current rom with ADB.
http://oi60.tinypic.com/2eefzuv.jpg
But as long as that doest a full clean rom install its not helping me anyway.
i really hope someone has a easy and quick way to do a fresh install that will really make the Phone like it was just out
of the box software wise. no root no changes or anything as factory reset is not doing that for me.
Thanks in advance.
Hutjeflut.
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.
