[Q] bricked my phone

hi...guysss.......i bricked my phone how can i put zip file in sd card......no system in my phone or sdcard also been empty

Make sure all power is off, then hold both up and down volume and connect a USB cable then restore from kdz. Your phone is just soft bricked.

[q] cant unroot my phone or delete super su

I RECENTLY UPDATED MY LG G3 TO LOLLIPOP 5.0 AND I CANT OPEN SUPER SU, I TRIED DOING ABOUT 5 DIFFERENT THINGS TO UNROOT MY PHONE... WHEN I DO THE PROCESS WHERE I PLUG USB INTO COMPUTER AND HOLD THE VOLUME DOWN WHILE PLUGGING IT IN, THE PHONE WONT DOWNLOAD IT STAYS AT 0%. .. THE LG FLASH TOOL I CANT DOWNLOAD. IT KEEPS BRINGING UP ERRORS.. I TRIED DOWNLOADING FROM 3 DIFFERENT PLACES... I JUST WANT TO GET BACK TO MY STOCK PHONE....
After trying all of that to remove the issue when launching SuperSU "There is no SU BINARY installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 4.3, you need to manually re-root - consult the relevant forums for your device!", it still isn't resolved.
Any help?
THANK YOU IN ADVANCE..

Well there is a lot of ways to restore back to stock just follow this thread. Best method is the KDZ or flash a restore zip via TWRP

Make Sure the LG Usb drivers are installed. Then The phone must be off. After that hold the Volume Up button, plug in the usb cable to the computer while holding the volume up button. Let go only when you see the screen get to the download mode. Only then can you use the LG Flash tool for KDZ

That is exactly what I did when I plug in my phone it shows the download mode icons in the middle for about 0.3 sec and goes straight to the "fastboot mode started" with the whole screen black. it does it very fast it doesn't go to the downloading firmware part

If download mode doesn't work you need to push these files fastboot with adb commands. Go to THEPagel's thread with all the stock zips and extract those out and push each and every individual files via fastboot. Remember you need fastboot and adb installed on your computer before proceeding. If you are new to fastboot and adb then suggest searching for a tutorial on that before even attempting this.

why don't you just flash a stock 5.0 lollipop rom that isn't rooted. Don't flash su and then you'll have a stock rom without root and twrp.

like I said in my other post. Download a stock 5.0 lollipop rom. After your done flashing don't flash twrp. It's going to ask you that you're not rooted and if you will like to root. Press no then reboot. There you go back to stock without twrp and root.
ThePagel has an untouched stock rom

Thanks alot man I will try that later today thanks

LG G4 flashing CM13 Fail

Hello everyone. So, yesterday I flashed the new CM13 on my h815 international. I have TWRP Installed but CM13 has overwritten my backup, so I don't have a backup to go to.
Current state; What should I do? The only thing i need is to get into ADB/TWRP because when I start my phone, it crashes instantly. And USB Debugging isn't on, I cant enable it because i only see "System -UI" has crashed. ADB won't find my phone, not on usb 3.0 or 2.0. I tried to get into TWRP with Hardware buttons, that also didn't work.
My phone is rooted and has a unlocked bootloader. What should I do? I can see my phone on my Windows PC when plugged in. Please help
Greetings from Switzerland

EDIT: I WAS ABLE TO RESTORE EVERYTHING WITH A KDZ. THANKS GUYS

Which version?

Which version of the KDZ are you trying to flash? And chances are that your device isn't being picked up because of the lack of USB debugging.

Put your phone into Download mode.
You should be able to flash a .kdz then.

My PC is not recognizing phone at all so the process won't even start. That is maybe because the battery is empty. I will try that after I charge the battery with my colleague's phone but I think that is impossible.

The same here, when powering the mobile on it shows
Boot verification Failed
-cause MISMATCH_SIG_LEN
I don't have a custom recovery. The only screen I could see is the default mobile recovery which only offers erasing data, any suggestions.

Not at all, just open it, shortwire the 2 pins, use boarddiag to flash proper partitions and in the end when download mode is fixed just use lg flash tool or lg flash tool 2014 to flash your kdz(or tot)

I stored even the kdz file in the intern Memory, but I have no Chance to get it wether in download Modus nor in twrp Modus. What do you mean with "now flash your rom with lg up" . What is lg up??

Hi, I solved my Problem bei using Google Universal USB Drive. There it's possible to specify your item and edit the right ID's. There is a description in the net. After the USB ist connected now, you can normally Flash your Gadget.
