Installing 2.8.x.x TWRP - AT&T LG G2

What method are people installing newer versions of TWRP newer than 2.7.x? The latest .img file on official TWRP site is 2.6.x, AutoRec installs 2.7.x, which is too old to utilize the flash .zip install. The "dd" method also says to use an .img file. Am I missing something? Can I do it via fastboot? Thought that's like the "dd" method. I also tried to download 2.8.0.0, 2.8.1, 2.8.3, hoping to incrementally flash, but that did not work either. I just did a LG Flash tool revert back to KK because my attempt to root LP resulted in Security Error boot screen.
I did notice the recovery.img file in many versions of the .zip file have the same date and it's from 2008. Is it supposed to be the same and so old?
I don't know if this is related, but whenever my G2 screen turns off now and turn back on, I'm getting whitish vertical garble screen. I did something wrong by trying to flash .img file I extracted from .zip file not knowing it's not the right image file.

I've come across this today (my OPO was rooted and I had TWRP installed), I was able to install the OTA via returning the OPO back to an unrooted stock build. You can easily do this via getting the 'Fastboot' zipped version of your current .....1NO build.
Once you have this, you only need to fastboot flash the following: - boot.img, recovery.img and system.img
After flashing just these three images, yes you'll loose root but you'll be able to OTA update to the ......2QL build via the normal phone method - hten if you want, you could then reflash a TWRP recovery and re-install a supersu.zip
One thing I forgot to add, which maybe helpful to others as it took me a moment to realise, both boot.img and recovery.img flash without issue, but due to it's size to flash the large system.img you'll probably need to brake it down into flashable chunks, notice the change in fastboot commands: -
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot -S 512M flash system system.img​

OTAs can only be flashed through stock recovery..applicable to all devices
Hello,
on the same subject, I am looking for explanations on how to create twrp flashable files for ota updates. Do you know where I could find any resources?
Thx
I had the same issue while installing the incremental update (I got root and TWRP); I solved it simply installing the signed zip of ...2QL version which was pulled out yesterday afternoon. My only concern was about root that could be wipe away with the new installation, so I directly installed SuperSU via zip. Everything works fine till now

Broken recovery on Huawei GX1s (SC-UL10), Fastboot works

Hello,
I tried to flash TWRP, and selected the Huawei image closest to the GX1S (SC-UL10) (Ascend Mate 2), and flashed this to recovery. I probably shouldn't have done this...
I am now stuck in fastboot. Though fastboot itself works fine.
I am unable to get into recovery
I am unable to boot the phone
I am unable to use ADB
I have tried flashing other twrp or cwm recovery images to recovery without success (the flash succeeds, but still unable to get it to recovery or boot)
I have downloaded what I believe to be the official firmware from Huawei
Forced Upgrade (by putting update.App into dload folder on SD card) did nothing (Does it need working Recovery for this to work?)
I tried various Huawei extract tools and perl scripts to extract stock recovery.img, but none work on this update.App file (It seems not to follow the structure these scripts expect)
My theory at this point is:
If i can flash a working stock or modified recovery, I can then use the force update method to get it working
There should be a stock recovery.img inside the update.app, though i seem unable to extract this using available tools
I have been unable to find a cwm or twrp recovery for this phone (SC-UL10)
I am hoping that someone might point me in the right direction to find a working stock recovery.img, or a working custom one. Or any other ideas that might help me get the phone running again.
Thanks!

Flashable zip of factory Android 5/bootloader?

Does anybody have a recovery image or zip of Android 5?
I seem to be having problems flashing via adb. I have previously flashed the factory img file but can't seem to get things working any more and flashing zips is much quicker/simpler anyway.
Re-installed Android SDK and not fastboot etc work.

I installed twrp on my pixel on 7.1.1 it reboots to tarp again I got it to boot to the p.s. by clicking reboot / a on bottom left option but get error codes and can't open a lot of apps. I tried to install a tom and clear device cache and cause fails. Anyone know how I can fix this. I thought I used all the latest files

Did you fastboot boot into TWRP, then flash twrp-pixel-installer-sailfish-3.0.2-0-RC1.zip? Were you stock prior?
Installed img through pc then installed the zip file with twrp. I found a article here stating I need to flash stock ing to get back to normal

Yes, you are not supposed to install twrp, just boot into it. If you install it by mistake, you go back, flash stock boot.img, and do it again.
This is from Dees_Troy's post located here
https://forum.xda-developers.com/pixel/development/twrp-alpha1-pixel-devices-t3500314
Installation:
If you already have TWRP installed: Download the latest zip and install the zip using TWRP.
If you do not already have TWRP installed: Download both the img and the zip. Copy the zip to your device. You will need to have fastboot binaries and the correct drivers installed. Power off your device completely. Hold volume down and turn on the device. Your device should now be in the bootloader. Connect the device to your PC. Open a command window and run the following command from the proper location:
fastboot boot path/to/twrp.img
This will temporarily boot TWRP on your device. If you are using a lockscreen pin/pattern/password and do not get prompted to enter your passord, reboot to the bootloader and try again. Go to install and browse to the zip and install the zip. If you are currently rooted with SuperSU, you will need to reflash the stock boot image before installing TWRP. After installing the stock boot image, follow the instructions for installing TWRP. Once TWRP is installed, grab the very latest SuperSU released on 2015-11-15 or later and install SuperSU.
If you accidently flash TWRP to your device using fastboot instead of temporarily booting the image, you will need to download the latest factory image for your device and reflash the boot image.
@Tulsadiver First off, thanks for the post on this. I installed TWRP to slot A by accident and am finding myself in this same predicament (though I found that I can boot by switching to slot B). I found another post online that mentioned what you commented on, specifically:

Having previously downloaded Oreo 8.1 and setup root, I had loaded into TWRP, went to install, selected the TWRP zip, and installed (as per what you had suggested and what I read earlier). This is what led me to the current problem, making me realize that I'm missing something in the description. Now, I likely don't need to flash TWRP (I don't develop and used flashfire to do upgrades) but my last upgrade left me rootless and I felt having it installed would make life a little easier. I was hoping to ask for a clarification on the TWRP install.
Also, you mentioned flashing the stock img. Do you mean from the android OTA downloads? I was getting a corrupt file error when I tried flashing that to slot a...

Things have changed with 8.1. you have to root with magisk. From slot b you cannot fastboot flash boot_a boot.img?
I believe the instructions now are to boot to TWRP, install TWRP pixel installer zip, then flash Magisk zip
Here is where TWRP files are here

I hadn't tried yet. I was worried about messing things up further without asking for help online first. I'll give this a shot later. Does boot.img refer to the android image file? (ie: what I'd download from the OTA site?)

Yes, the zip file that is located where the flash-all.bat is. Unzip it and flash the boot.img.
I bought a Pixel 2 on swappa. It had different bootloader's on slot a and slot b. I couldn't flash updates when on slot a. I thought I was hosed but from slot b I could flash to slot a so now I'm fine. Slot a had a preview bootloader.

Can i flash a kernel with odin?

Sup!
My phone is unable to boot due to the error "Could not do normal boot. Invalid KERNEL LENGTH!"
I already downloaded the kernel i need but since i can't even boot into recovery, i need to flash it with odin.
The file format is .zip, i couldn't find it in .tar format and inside of the zip also isn't a .tar but two .img files and some other important looking stuff.
Is there any way that i can flash the kernel back on?
TIA for any help
Will this work, its a bit old but you can give it a shot.
