[lg l7] bricks after downgrade - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

Hello, so i tried to downgrade my phone from v20d(4.1.2) to v10k(4.0.3) everything went good, but then KDZ_FW_UPD closed(error) with message SUCCESS, and phone quit from emergency mode and stuck on 2nd LG LOGO(gif).

L7 P700 bricked, need help!!!

So after installing cyanogen on my phone for the first time it all worked fine but I had no mobile data/signal at all, so I decided to try something else, but once I tried the install failed, and I didnt have access to my SD card from recovery mode, so when I tried to reboot the phone it just went into the LG logo and now its stuck at the battery screen. I've no idea how to get back to recovery mode, I can only get into emergency mode, PLEASE SOMEONE HELP! :crying: :crying: :crying:
If you can get into emergency mode, that's enough to save your phone! You can flash your phone with stock firmware (pick the one you need from this site: http://lg-phone-firmware.com/index.php?id_mod=13)
You can probably find multiple threads on how to flash a KDZ file to your phone on this forum!
Good luck!!!

you didn't have signal because you probably didn't have v20baseband flashed. You can enter emergency mode by taking out phones battery ,holding vol up and connecting phone to usb. Then flash this with kdz http://forum.xda-developers.com/showthread.php?t=2176430 ,after that you can try flashing cmw again but you will need to change baseband to have signal if you come from ics(v10) to JB+(v20)

[Q] LG Optimus L7 won't do stuff [SOLVED]

Hello everyone,
I have a somewhat big problem.
I recently installed a custom ROM called MIUI V5 for my optimus L7.
When I installed it I forgot to install GAPPS.zip
I didn't think much of it, so I just booted my device it booted normally and showed the android jellybean logo with a loading bar saying "Optimizing apps please wait" after that some error messages showed up saying : "Unfortunately, System UI has stopped." "Unfortunately, the process com.android.phone has stopped." "Unfortunately, Xiaomi service framework has stopped." Clicking OK on these pop-ups would close them and then they would re-open in an instant.
I have looked everywhere for a fix but unfortunately I can't boot into recovery mode using the volume up( or down, tried both stuck on LG logo) + home + power button combination. I also tried to flash the phone a stock rom while in "Emergency mode!!" with KDZ and KDZ couldn't find my phone, I had installed every driver I could find but it didn't work. I searched the XDA forums for hours and yet still, no fix. I am truly desperate for a fix because I want to be able to use it again.
Can someone please help me out/ provide me with some more options?
Thanks for reading and thanks for helping in advance
If you have any questions about things I left out, feel free to ask I will respond to them all
Hi. Try putting phone in download mode, in my L5 i had to pull out battery, and while pressing vol - plug phone into USB - do this with battery pulled of your phone, dont insert it!!!. Next use LGMobile Support Tool, then go to options>upgrade recovery. It should find your phone. Then go what app wants u to do Hope it solved ur problem, it solved my bricked L5, i couldnt use KDZ. Good Luck

Completly messed up LG G2 , very complicated case :X

Hello to everyone here is what happened.
I rooted my LG G2 and i started messing with the uninstal application, after an hour it happened that i uninstaled stuff that i need and when i tried to back it up i couldnt, i noticed that my gallery isnt working, i decided to make factory reset, after the reset i couldnt work with settings-->general-->everything there i try to open says "unfortunetly settings has stopped working"". Then after abit of research i decided that the only way to fix the phone is to flash stock firm, so far so good but i cant enter download mode, actually i cant enter recovery mode with buttons too. Phone is working though, you cant work with settings like turn on USB debugging but phone works otherwise. Then i decided to instal TWRP manager, via TWRP manager i was able to enter android recovery mode, in which u dont have ADVANCE---> TERMINAL COMMAND, so i decided to flash TWRP recovery, after flashing now i cant even open the android recovery mode, phone still boots and works!!! Sorry if i explained it bad, please help i am actually very desperate at this point
bump :good:
Great news, we fixed it thanks to KitKat recovery for LG g2, and to SQL lite, if someone has the same problem i can help him, good luck

Cant boot up LG G2

Hey
I was on ressurrection rom and tried to go to Cloudy G2. Since cloudy asks for kk bootloader i used http://forum.xda-developers.com/lg-g2/general/d802-bootloader-changer-1-1-jb-kk-lp-t3104380 with the kk file. Installed cloudy with no issues. Rebooted phone and never again saw the light...
Been for several hours trying to fix it, reading, but it's 04am and i cant see clear anymore. Its my only phone and i need it
So... it does not enter recovery... After flashing i try the combo keys and nothing
I tried to use use the LG Flash tool to revert to stock. I downloads the kdz file but when starting to upgrade it gives an error.
Also tried follow the thread about reverting to stock using lg flash tool 2014 but the same error happens,,, switched usb cables just to be sure...
ideas are accepted... thanks
hmm, maybe wipe your phone AND try another flash tool perhaps?
Can you enter download mode? Do you get black screen or LG logo?
I would wipe if I could get into something to wipe it
Yes. I did get into download mode. But it failed using LG flash tool
I got it figured out and will post on case someone needs it.
I was able to enter agAin in recovery by using the combo keys, power + volume down and when LG logo appears release them and press both volume keys. That did it. Once again in recovery I flashed again kk boot loader, wiped all and flashed cloudy Rom. This time went all ok. Go figure, I did the same thing
well atleast it works now eh?
its working great now.. even better now that today i managed to make my gps work and fix in 5 seconds
Kudos m8! Glad you fixed it. Its annoying having a great device thats not functioning or give us back enough for what we paid for.
