Hello,
after root and bootloader unlock I was trying to instal recovery. Application says that recovery was installed succesfully, but after reboot it stops at logo LG. Now I have only 3 ways - recovery, upgrade and charging mode. Wipe data/factory reset didn`t help. I tried to install soft from beginning by LG Mobile Support Tool, but it didn`t recognise my phone, even after install drivers. Two months before it works good (LG software), but now it has problems. I used LG Flashtool (http://forum.xda-developers.com/showthread.php?t=2179126), but it still doesn`t detect my phone (device is in upgrade mode ofc). At the beginning I could change setting "LGE CDMA USB SERIAL PORT" and disable "PC MODEM", but now I can`t see that in devices manager. In addition when I plug in my LG, Windows sounds like its connected. Now I`m working on 8.1, but when I tried this same operations at 7 it also didn`t work. I was searching a sollution, but I didn`t found it. Do You have any ideas? Please help me, I need my phone alive. Thanks for replies.
I`m sorry, if I wrote this in wrong place.

Hello, I have the following problem. As in every other thing ive done to this phone (root, installing twrp, installing xposed) I always thought my model was LG-H502F. Though, my model is LG-H500F, I bought it from Greece, I recently bought Huawei P8 lite 2017 for myself and I gave my old LG to my father, he tell me that sometimes it lags and he is right. I think it lags because I uninstalled Xposed (flashed the uninstall zip using twrp) and also removed root, because he didnt need those things in his phone. The question is: Is there somewhere I can get the stock LG-H500F zip and what guide should I use? Ive been searching for a while now and can't find many topics related to LG-H500F. Thanks

I had installed CM 13 on my LG D415 and it was working perfectly until my phone battery died, and after I turn it on it shows the cyanogenmod logo and it won't load the lockscreen. It can enter download mode, but its not recognized on my computer and adb commands don't work on the work to enter recovery. Any ideas on how to get it back to normal?

If the phone enters download model (one can tell by its display) then you should be able to flash KDZ using LG Flash tool. Make sure you have the latest drivers and try different cables and/or computers.
