bootloop after KDZ HELP!! - G3 Q&A, Help & Troubleshooting

Okay so i tried flashing multirom kernel and after reboot from twrp i got a message saying fastboot and the screen stayed blank
i reentered twrp flashing twrp multiboot thinking that it would help yet problem persisted. i then decide to flash a kdz using normal flash then after that was complete my phone basically wiped and bootlooped. tried the same with CSE flashing still got a bootloop i then decided to repair upgrade from the pc suite and it worked but it downloaded a bloated rom because my carriers simcard was inserted in the process i think. so i decided to not waste time and flash a kdz in normal and factory reseted and the same happened with CSE now im currently doing the pc suite again. any help with this?
also id like to ask that if i flash cloudyg3 will i beable to return to stock without using tot or does it have to use tot to restore to pure stock?
my twrp was 2.8.6.0

Help Needed With Flashing After Bootloop

I recently flashed CM12.1 on my S3. I was running rooted stockmod 4.3. Everthing went fine. I made a nandroid first. I was able to flash back to with my nandroid and then back to a nandroid of CM12. I tried to flash back again and booted into Touchwiz ROM with no Google services and most of many (too) many apps gone. I then tried to flash back to my CM12 Lollipop nandroid in recovery and got stuck in a bootloop. I could not get past the the Teamwin screen.
Even though my USB port is dicey I was able to use ODIN on my pc to flash back to stockmod_root 66. I then installed TWRP using TWRP manager on device. This went fine.
I then tried to flash back to CM12 in recovery using my nanback but the phone reboots after a few seconds with any task, even just wiping partitions. I am also now getting an error message after trying to load the same stockmod I used successfully earlier. The message is in Chinese so I have no idea what it says.
Any hope here?
Edit: I managed to load the stock image in ODIN and it is flashing now. Still do not understand what did wrong so as not to be able to restore my nan back of CM12. Was there a problem with my installation of TWRP with TWRP manager?
Thanks

Recovery is gone but i have cm12.1 ?? Help!

Ok so recently I soft bricked my lg og pro (e980) and I tried to flash back to stock using the lg flash tools method from madmack and it only sorta helped me, It for one did not flash it back to stock as I still have CM12.1 installed, but it did get the phone to boot, after that it booted in cm and I set it up as usual and then went to flash GApps, I went to do this and the custom recovery is gone and every time I try to flash again using LG Flash tools I get stuck at ...recovery error! F0000002, and if I try and reboot the phone it factory resets so nothing I do is saved, Thank You in advance!

Help!! Full wiped LG G4

Hi. Im new to rooting and on the attempt to install lineageos, i got stock in full wipe.
First i unlocked my bootloader and then installed twrp. everything went well so far, but in twrp i made the mistake of doing a full wpe. now i dont know how to boot into custom recovery, if it even still exists on my phone. i also tried the lg flash tool, but i always get the connection to server error. would be really gratefull if someone would help me out. thxs
so... you don't tried enter to recovery via key-combo? (Vol Down+Power).
If you can enter to Download Mode, try to flash a KDZ with LGUP.
I can't flash kdz because lgup not recognized the device because i flashed a old marshmallow system on my lg4 with v30 port ..any help

Try connecting to your phone in Android SDK/Platform Tools.
Type adb reboot recovery and see if it will boot into TWRP. If it works, you have choices to restore a backup or flash a new rom.
If it doesn't boot into TWRP, make sure your TWRP recovery.img is in the same folder and try re-installing by typing fastboot flash recovery TWRP.img (using the file name of your TWRP image).

Help flashing back to stock, tried everything.

Hi, i'm having trouble flashing back to stock.
I've got the latest stock firmware from sammobile.
Using twrp to install it says missing META-INF as the firmware zip isn't made the same as custom firmware.
Adding the tar.md5 to ap in odin flashes the boot and recovery but goes extremely slow when it starts flashing system (left it 2 hours and it hadn't even got half way) I'm guessing that's not normal.
I took a backup with twrp before I started flashing in twrp which flashes fine but I get endless boot loop when trying to start it.
I've tried fastboot but it doesn't detect the tablet.
I've tried different usb ports, cables, different versions of odin and different stock firmware. I'm ready to throw it out the window.
One thing to note is the [P600][Touchwiz] Marshmallow Rom 20170622 works great but also boot loops when I turn it off and on again, I have to boot into twrp then choose reboot in there and then it boots ok, that doesn't work with my twrp backup though.
Anything I'm doing wrong?
Thanks.
Well for some reason after installing marshmallow rom again then installing my backup it boots fine, havn't a clue why it failed to boot the other 4 times.
Nope
Back to continuous boot loop after second reboot.
All I did was turned developer options off and it's boot looping again.
Flashed original stock boot.tar.md5 and recovery.tar.md5 then factory reset and wiped cache but still boot loops.
Is it because I flashed a Marshmallow custom rom so it so you can't downgrade to a lolipop rom even though it's stock? Boot loader changed? Kernel?

I'm not quite sure what your problem is but you should be able to downgrade, I've done it before.
Try this guide first. I've had success with it.
If all goes well you can then try to flash your stock ROM. The one I've flashed successfully in the past is the one in this post.
Good luck!
You may need to repartition your system. Tick the repartition in Odin. **All data will be lost**
