Soft Bricked D855

Okay, so a few days ago I had a completely stock LG G3 D855 v30n Marshmallow. Then I decided I wanted to root it and flash fulmics. So I flashed the v30b kdz with lg flash tool and rooted the phone with rootking. Everything worked perfectly until I flashed the ROM. I made a nandroid backup with TWRP and I downloaded the fulmics 6.6 zip of the xda forum and put it onto my external sd card. I tried to flaash it onto my phone but it wouldn't work (it kept reloading into recovery mode every time I tried to flash it). I thought the problem was I was using an old version of TWRP. So I flashed my backup and soft bricked my device. I have access to download mode. Could someone please help me in unbricking my phone and is it even possible to flash a rom in my situation? Thank you very much in advance.

Ok so,
Connect your phone to your PC.
Go here TWRP and select the "official".Download the latest one,move it to your phone's SD Card.Flash it with TWRP.
And after that,Full wipe and reflash Fulmics.

Backup your data of the current ROM and do a full wipe.
If the same thing happens,reflash the ROM.

Well if you tried Flashing MR.Bump and nothing worked,the only way is to go back to stock.

If you have access to TWRP you can also directly flash a custom ROM as well.
You just need to format everything without the internal storage first.

I've the same model, working fine with me, so let me tell you what I'd done..
downloaded the recovery from moto.shreps.fr by choosing my device and the last 3.1.0 build and renamed it to twrp.img
try the same and first, boot this twrp temporarily using
fastboot boot twrp.img
if twrp works then return to fast boot and flash using
fastboot flash recovery twrp.img
done. ?

is that problem persisting during backup or restoration?
if you're having problem in restoration then
Decide which backup file you want to restore.
3. Rename that file from "msgstore-YYYY-MM-DD.1.db.crypt" to "msgstore.db.crypt"
4. Install WhatsApp
5. When asked to restore, tap [Restore]

Help required with bricked Oneplus 3

Hi,
I have installed MIUI in my OP3 this morning, which was working fine. There was an OTA update, after installing it, device rebooted and entered into recovery mode and it was hanging there for more than an hour. Whrn I tried to reboot, it was off and never came up. Tried unbrick using MSM Download Tool and then I am able to get into boot loader screen. From there I have tried to flash TWRP, but if I reboot, I am getting this message only. Currently I have access to bootloader, if I flash TWRP and choose to boot from recovery (from pc), I have access to OTG also. But even after flashing a ROM, If I reboot, I am getting attached screen only.
I have access to TWRP, only when I chiose to reboot from All in one tool from PC.
Please help me.

you have to use method 2of unbrick not method1.it will flash whole stock rom , then reboot enable developer options etc then flash twrp recovery then go ahead.

Use Method 2. Make sure to follow all steps. Please do quote me otherwise i do not know if you need any further help.

You flashed oficial beta update on mui rom and you have a mess.
Download official OP 4.1.6 rom and try to flash it.
if its not fixed the try wipe everythng (system data ect) and then flash the rom

I am in travel now, having limited internet connectivity. I will reach home and then try to download official OP as you suggested.
I do not have data in phone, all the data is already copied to laptop.

I was having the same problem like you how did you solve it ?

Screen stuck at boot after flashing ROMs

So I tried flashing roms using OrangeFox. I cleared everything but internal, sd, usb memory. Added ginko firmware to queue, McLaren OS, disable dm verity. Rebooted to system and it was stuck at the redmi logo with powered by Android at the bottom.
After some time I went back to recovery and cleared everything but internal blah blah and flashed just an Oxygen OS gsi for AB (.img). Rebooted to system same result.
Next I did the same with an Xperia for AB gsi and then Oxygen for A only. Always same result. What do I do?

imho you need a guide special for RN8 how to flash GSI rom's.
I only saw one guide on XDA for RN8Pro, which is another phone.
For RN8 (gingo/willow) you can use a generic guide
On russian forum I found a complete guide. Maybe you can see there what you can do better.
Use Google translate or Chrome for reading.
