i tried installing a custom rom on my g pro 2 but eventually the device got some errors. i tried to restart but the phone wouldnt start. it boots to LG logo (not moving) and blank screen and same thing over and over again. so i tried to go for download mode, which is half gone. when i plug the phone into download mode, the first screen comes out, download mode. then screen goes blank and nothing else. my pc doesnt detect anymore, it just shows an unknown usb bulk device and 8 usb drives pop up.
i tried factory reset too but nothing. stays erasing forever.
i have the KDZ File already and the flashing tool. i just don't know how to flash it like this.
solved

Hi,
I have a Galaxy S (I900) which I attempted to root yesterday. Stupidly, I used the wrong root kit and when I rebooted I was left hanging on the startup screen with the network logo (orange) flashing.
My boot menu was disabled for some reason but I could however access download mode - which I did. Whilst trying to rectify this I downloaded a couple of kernels that were recommended to fix the problem but to no avail.
Finally, running out of options I downloaded Odin3Execution v1.00 One-Click downloader, connected the phone and clicked start (which was also recommended to me). This completed successfully but when the phone tried to re-boot I was left with a flashing AT&T logo (which is not my carrier) and download mode no longer executes when pressing the buttons. Also, when I plug the charger in the screen just goes black.
I realise that this is my own stupid fault but i'd really appreciate some help on the matter.
(would a USB jig get me back into download mode?)
Okay so I'm pretty new to the whole forums thing so please bare with me a bit. I flashed CloudyG2 3.1 and wanted to do a a factory reset so that I could start anew but whenever I tried doing so it would fail and lead me to TWRP. So I tried doing the format through there and then that's when I believe it even deleted my OS. Now the only thing it does is sit at the LG boot logo while the notification light slowly flashes blue and green. I can still go into TWRP but am unable to go into download mode. I've tried sideloading but whenever I connect my phone to a pc (I've tried multiple cables and pc's) I get a message that says "The last USB device you connected to this computer was malfunctioned". I went to get my port replaced and they said the screen stopped working so they put in my old one. I don't know if I should just get the port switched to the new one and try to flash it and pray the screen turns on afterwards or is there a way to get this USB to work. Any advice would help a lot! Thank you!
Hey everybody,
I just have a serious problem with my LG G4 H814. Yesterday I was just sitting there, using some Apps and suddenly the application ges frozen and after that the phone just more or less turned off. (So the screen gets black). I tired to replace battery and all this stuff but doesn't work.
Next thing to do for me was to boot into TWRP try to fix problem with wiping dalvik cache and/or restore by nandroid backup...
Problem beeing: I cant boot in Recovery Mode either! Just doesn't work... So I tried to boot in the Stock Recovery of LG to do a factory Reset, wasn't able to do that either!
So last try... reboot into Fastboot Mode (Download Mode) and try rebooting into recovery via adb comands...!
Problem beeing: can't get into Fastboot Mode!
I tried to connect Phone via Bootloader but deosn't work.
So now I'am at a point where I can't turn on my Phone! I mean it wont start up...The screen stays black, no Logo is showing up, no LED NOTHING!
The battery icon doesn't show up when I try to charge my phone...
So tell me: WHAT THE FVCK IS HAPPENING HERE? Do you have any idea on what to do except for bringing it to carrier?
I just want to get to my Data on phone...rest doesn't matter. I could set up everything again?
Device information:
LG G4 H814
TWRP
Xpsosed Framework running (v75 i think)
Modules were working just fine (before everything happened I did an reboot so that the modules are active!

You might want to post in the G4 general or where the H814 model is specific (is that T-Mobile?) This forum is specific to the H810 ATT version.
Additionally, you can see the posts about TOT method for restoring your phone, however this will completely wipe your data.

I think H811 is T-Mobile.
Lg G4 H815 T mobile
Same here with my H815 from T mobile. After a forced update of a start up T mobile screen it stops working and gets in a boot loop. all key combinations don't work so can't start in safemode
my g4 h810 does not turn on. no download mode, no recovery, black screen but can be detected by PC when connected via USB. recognized qualcomm 9008 thing. drivers were successfully installed. Mobile feels lifeless except when connected to PC.
any ideas what's going on, does it mean that my phone is hard-bricked? how to resurrect it?
Hi all, have a rooted OPO that was running ExodusOS. I decided to try a flash of Lineage and so booted into recovery, backed everything up, flashed it. Everything seemed to go okay but after the boot logo the screen just goes black and stays that way until it gets shut back off. I went back to TWRP, loaded my backup and all seemed well as I was still able to use my old backup just as normal. Well, I tried reflashing Lineage from TWRP again and I still get the same black screen issue. This time, however, the phone will neither boot into Fastboot nor into recovery mode and just goes straight into loading Lineage. Because of this I am left with a soft brick until I can get this straightened out. I tried connecting the phone to my PC but it is not detected as a device. I only need to boot into my backup one more time so that I can back everything up, so even if it's only a temporary fix, I'm okay with that too. Any suggestions?

Sounds like a Hardware issue? Sorry to say what your saying doesn't add up and or make sense. Fastboot should work no matter what even if you soft brick it and mess up recovery. I suggest letting the power fully drain maybe and google how to fast boot in case you are doing it wrong.

I've tried that but it can't find the phone. The phone gets detected as a new device in windows as evident from the device connection sound but it also never shows up in the list of devices from My Computer.

I agree with what @Shinobi_warrior said.Seems like you just have a soft brick,so you should be able to boot into fastboot mode without any issues.Are you sure you're doing it the right way? Did you try draining battery completely and then booting into fastboot(yes,you don't need much battery to boot into fastboot mode)?
Well I was finally able to get the device detected by ADB, but it just shows as offline. I attempted to use the repair kit and nothing seemed to happen. I also attempted a different tool (https://forum.xda-developers.com/on.../oneplus-one-toolkit-manudroid19-gui-t2807418) and then booting into either fastboot or recovery that way, a terminal window pops up and quickly disappears, and then nothing else happens. I still see the TugaPower boot logo and it still goes to the blank black screen after this.
Had it for 3 years now, it first looped in October 2017, broke all the sensors but has otherwise been working fine since. I also rooted it about 7 months ago in case that makes any difference with recovery. During both of these loops I have been unable to reliably get into recovery/download mode. I left it alone for an hour earlier today and came back to find that it was somehow in Odin/download mode with the text in the top left but still on the boot screen. So I plugged it into my computer, it was detected and then I flashed it with the correct G930T firmware and home csc. Got the success message in Odin and it seemed to be working but it was just stuck on the boot screen now. So now I've just been trying to flash it again with the other csc but it has been failing for a lot of different reasons and I don't know what any of them mean. I did manage to get it to power on a lot more reliably and into download mode, but still having problems. The biggest problem is when I get to either the download screen or warning screen, the screen suddenly gets all glitchy and I can't do anything. Whenever that happens it also shuts off after 10 seconds. This also happened on the Smart Switch emergency recovery screen when I cancelled a stalled flash and then tried to flash it again from that screen. I've also gotten errors when trying to flash from the download/boot screen. The ones I can remember are "unsupport dev_type", "secure check fail : tz eMMC write fail : tz" and "secure check fail : hyp eMMC write fail : hyp". I can't even find anything else on these errors and have no idea what they mean. I also have no idea how it is getting into Odin mode on the boot screen but so far that is the only way I have been able to do anything since I can't get into download mode the proper way. Lastly I tried to check in Smart Switch to recover it but it says the device is unsupported and there is nothing in emergency recovery.

When you flash with Odin tick "'re partition" in Odin options.
When "pass" appears disconnect phone from pc. Force reboot by holding home+volume down+power.
As soon as screen goes black press volume up while keeping home and power pressed. When recovery menu appears choose wipe / factory reset. Then reboot.
What is obviously very important is you are flashing the correct firmware for the device in the first place.
