H910 TRWP Recovery - LG V20 Questions & Answers

While following DirtySanta's guide I believe I may have accidentally copy/paste the whole post and it may have read these commands:
fastboot erase system
fastboot reboot
In TRWP Recovery it shows no OS installed.
Am I SOL?

[Q] Possible Brick?

I'm selling my Nexus 7 and I think I got a little click happy while clearing it out.
I had reinstalled 4.3 and then for some reason I formatted the data. Got stuck in a boot loop.
When I try to install the image again I get the following:
Updating partition details...
E:error opening '/data/media'
E:error: no such file or directory
Any help would be appreciated!

All this means is that your userdata partition got all jacked up. It's restored when you boot into a rom, but of course you can't boot into a rom cause something else must have also went awry. So I suggest you wipe everything and start over. Follow along with me, this will be fun!
Boot into fastboot, send fastboot unlock command if your bootloader isn't already unlocked "fastboot oem unlock." Accept on screen. Reboot back into bootloader/fastboot. Issue FASTBOOT ERASE USERDATA, FASTBOOT ERASE RECOVERY, FASTBOOT ERASE CACHE, FASTBOOT ERASE SYSTEM. Then flash TWRP recovery using FASTBOOT FLASH RECOVERY [NAME OF TWRP GROUPER IMG]. Then adb push your rom and gapps back to your tablet using ADB PUSH [FILE] /SDCARD, then flash your rom and enjoy a fresh clean tablet!
That's why I prefixed with 'possible'...
Thanks - I followed this guide later in the evening and got it all up and going again.

I can go into the bootloader and then went to recovery get the android red exclamation mark guy so stock recovery has been flashed. I just don't know why it's bootlooping?
Did you backup and restore EFS at any point. If so you're bricked.

And if you are bricked (TWRP 3.0.2-1 EFS restore?) you need to erase those partitions via ADB to fix it.

ok what is the command to do this. I put my phone in bootloader and what command do I fastboot. and would I reflash the factory image afterwards. thank you
how do i erase efs partition
so I have stock recovery how would I erase my efs partition?
Solved
thanks to @ ultyrunner I flashed twrp and then ran the follwing adb commands to make my phone boot up and it worked. you sir are my hero!
If you have been bricked you NEED to Erase the EFS partitions and that will fix it immediately.
For the Nexus 6P go to TWRP. Then on PC Open Command Prompt with access to ADB ( Android Debug Bridge) and execute the following commands:
ADB shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384
and
ADB shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384
This should fix it for ANY Nexus 6P users.

You can run ADB commands on stock recovery. You need to ensure you have current ADB/fastboot drivers installed and that your computer recognizes your device.
Once that's working, do some research on the exact process but in a nutshell boot into bootloader, reboot into stock recovery and get into the recovery menu, use the rocker to select "update over ADB" and then you can doublecheck your computer recognizes your device and should be able to issue the commands to erase the EFS.

Fastboot Stock ROM and TWRP together?

Is it possible to install TWRP directly after Fastbooting ROM and rebooting? I.e adding twrp install instruction between the last two ROM install lines lines. Obviously twrp will have to be with the ROM in the Minimal ADB folder.
fastboot oem fb_mode_clear
fastboot flash recovery twrp-3.2.3-1-potter.img
fastboot reboot

[SOLVED] Can I install Nougat Fastboot ROM even if I am on Oreo?

I do not know whether my EFS and Persist are intact but I have backed them up. I had installed Pixel Experience 9.0 and then restored my TWRP backup to go to Stock Oreo, Build Number: OPSS28.85-13-5. This is my current Build, unlocked, rooted and has TWRP.
Can I follow this (https://forum.xda-developers.com/g5-plus/development/stock-firmware-npn25-137-67-5-fastboot-t3694738) guide to go back to Stock Nougat and then upgrade to the latest official update from moto?
I am asking to confirm as the Stock ROM given in the guide is Nougat ROM and I am on Oreo as mentioned above. I won't have any problems right? I do not want to lose VoLTE and my IMEI.
Any help will be appreciated.
Installed Oreo ROM via fastboot on my Moto G5 Plus [RETIN/Indian/ XT1686]
I am sharing my experience here so that it might help someone looking to flash stock ROM via fastboot. This is not meant to be a tutorial, but I will list out the steps I followed. I am not responsible if you mess up or hard/soft brick your device when following the steps I mentioned below. Always make a backup of your data/photos/videos/music and whatever else. Also make a backup with TWRP to be safe.
So instead of following the guide linked in the above post, I followed this one and successfully unrooted and returned to stock: https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-fastboot-flash-stock-oreo-t3848433
But I did not use the ROM linked by the OP in that thread. Instead I downloaded this one : https://mirrors.lolinet.com/firmwar...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
This RETIN ROM works for me because I have the Indian XT1686. I don't know if it matters but I had the same version (13-5) before, but I am not sure whether it was RETAIL or RETIN.
Anyways guys make sure you download the right ROM for your device if you are going to install via fastboot. You can download the right ROM for your device from here: https://mirrors.lolinet.com/firmware/moto/potter/official/
There are different folders for ROMs of different regions in the above link. So carefully download the one your device is compatible with.
Also, I installed fastboot drivers from here: https://forum.xda-developers.com/showthread.php?t=2588979
Follow the instructions and also follow the video tutorials in the post to install fastboot drivers if your phone isn't detected in fastboot.
Then once I had downloaded the ROM and installed ADB, I extracted the ROM zip into a folder. Copy pasted ADB Files into the same folder (download ADB Files that worked for me _ attached to this post below).
FInally I put my phone in fastboot (turn off phone, then press volume down and power simultaneously till fastboot shows up). Connected the phone to my PC. Then opened CMD in the folder where I had extracted the ROM and copy pasted the ADB Files. To open cmd in a folder, just type cmd in the address bar of the folder and press enter.
And then I copy pasted the following code into the cmd window:
Code:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash dsp adspso.bin
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash system system.img_sparsechunk.6
fastboot flash system system.img_sparsechunk.7
fastboot flash system system.img_sparsechunk.8
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot oem fb_mode_clear
fastboot reboot
The above commands will run when pasted in cmd and your phone will be flashed with the ROM. It took a couple minutes to install and then I had to press enter while still in cmd to reboot the phone. Then the phone rebooted. Took a couple minutes more to boot, so stay patient. Then once the phone booted, I disconnected it from my PC and set the phone up as usual. DO NOT disconnect the phone when the fastboot commands are running and the ROM is being flashed. Note that the above fastboot commands will only flash the ROM. It will not lock the bootloader.
If you want to lock the bootloader then follow the instructions here: https://forum.xda-developers.com/g5-plus/how-to/moto-g5-plus-fastboot-flash-stock-oreo-t3848433
Note that I haven't locked my bootloader. So you will have to try and see for yourself whether it locks your bootloader.
Also once I booted up I got update notification and was able to update to the Feb 2019 OTA security update. So I can for sure say that updates work. VoLTE, calling, camera, almost everything I checked works.
Cheers. :victory:

can‘t install or boot images on Oneplus 6t

Hi! My goal is to install twrp recovery on my Oneplus 6t but when i flash it with the command fastboot flash boot twrp.img it does just boot into fastboot mode and the OS is deleted. i can’t use the command fastboot flash recovery twrp.img because i believe i have an A/B Partitioned device because everytime i use this command it says soemthing like: can’t find recovery_a. I can‘t use the command fastboot boot twrp.img because everytime i use this command the phone is stuck on the fastboot splash screen. I need help!
You should flash a fastboot rom of your device to fix this problem
The command is fastboot boot twrp.img. You can only boot it not flash it from fastboot. Once In twrp you can make it permanent in the settings
