I would like to thank this wonderful community for all the help I have gotten over the years, I think this should be my first post.
For technical details of all I have done and learned on recovering the damn phone, skip to below the line, the rest is more of an introduction + some history.
In the past I have had a Canadian (BELL) Samsung Galaxy S2.5 as I like to call it. Specs similar to the S3 but not quite.
That was fairly easy to root thanks to odin.
Anyways, I have an LG G2 that I inherited from my brother, so I have some emotional attachment given he passed away 2 years ago (Age 36)... Reason why it is critical that I fix it.
I feel it's a great phone with excellent specs, with some flaws.
Hardware wise, this phone's digitizer seems to fail after a few years and stops registering touches.
Failed on my brother after 8 months, he got it replaced by videotron.
8 months after my ownership, same issue. I replaced the screen, which is a pain.
I dropped it a year later and broke the screen, replaced again.
Replaced the battery twice (First replacement battery was DOA) and... The internals of this phone are a pain to work with... to my limited experience at least.
The get to the point line as stated above.
___________________________________________________________________________________________
I wanted to flash my 4 year old never reinstalled phone, give it new life.
Researched a bit everywhere, verified in the phone what version it is, even most google results tell me this and the replacement screen is all the same.
it's a D801
After some work and research being clueless about working with this model, I finally installed
Started with getting Dev powers by spamming a specific key, setting usb debugging...
Using some application manager.
Installed
D801_AutoRec.apk
Towelroot.apk
From autorec, I installed the twrp and... fastboot... had no idea what that was.
Here I learned how to recover my phone.
This guy... super helpful.

Originally, I only did boot aboot recovery and iaf
After that, my phone rebooted to the LG logo and stuck, but the Download mode is working again.
At that point I did flash a twrp recovery and was able to run it using the command abd reboot recovery
I pushed different roms, but no matter what I do, always back to fastboot.
Found this video later on, originally found a thread here but for the life of me I can't find it anymore (too much history) (How to recover with LG Tools the original kdz
youtube link removed
Now... I could not find the correct firmware
I used this
T-Mobile KitKat D80120A_00
IT worked, my phone restarted as it was before my adventures, but under a tmobile d801
Here I am happy, I get the proper D803_AutoRec.apk
Install the recovery again...
Now I really broke my phone.
Retried the steps above of flashing aboot and so on...
Refuses to work.
So I figured, hey, I recovered it under D801 tmobile... I probably broke it with the D803 recovery.
Back to the download site, made another folder and downloaded all the D801 img's
Ran my script (well that's when I created it from being sick of typing it)
Now I boot Tmobile but it's stuck to All Auto Test - FTM Mode
SUrprisingly on wifi,, shows missed calls and picking up exchange emails...
When I try to Flash as I have before under download, it fails.
SO hey, it found a 300MB tmobile update... why the hell not at this point.
Can anyone link me the proper software I can try to recover the LG Tools ?
csmgdl link removed
and
csmgdl link removed
Don't seem to work
Did I mess it up beyond repair ?
Any recommendations ?
I am hoping for one of the following
If I get tmobile OS working
Retry the D801_AutoRec.apk given it matches the tmobile recovery that somewhat works and then attempt the original goal of setting up CloudyFlex_2.8, CloudyStock_2.7 or cm-12-20150325-UNOFFICIAL-d803
Pretty sure up there, most of those wont work, I just want a working twrp
All I want is this phone wiped with a clean efficient rom to use as a reliable daily.
All I do is phone, text, exchange, camera, some apps... nothing too fancy.
I am off to sleep
Whatever I do, I can't get out of All Auto Test = FTM Mode
Reboot, hold volume up
Down
Up and down
Power up
Power down
Power vol up and down...
Always to all auto test.
Swipe down, get to options, general, do a full factory rest...
Same thing. Grr
Okay dude, take it slow. There's only one way to correctly root/install recovery on this device - that seems to work for everyone.
Tell me if this works. Plug a usb cable from the phone into your PC. Shutdown the phone holding power, release power, hold up. Keep shutting it down and doing this again until you get into "Download Mode". Tell me if you manage this.

I have gone to download mode before to recover an oem image.
Now, I can't get to download mode after trying a number of times.
Ill give it another go tonight. Yesterday I got tired from the research, trial and error.
Thanks for your reply
With a calm mind, I fixed my issue.
https://forum.xda-developers.com/showthread.php?t=2613404
Press and hold power + Vol up and tap normal boot.
Didn't understand that at first.
Now let's see if I will break it again.
Still unsure if I should root it using D801_AutoRec.apk or D803_AutoRec.apk
Reason why I hate this phone.
Videotron LG G2 writes that it's a D801 but I read in other sources that it's a D803.
Now however, it's been restored to a Tmobile Firmware...
Okay, take it really slow. I've just completely rooted, put a custom recovery on and am now on Android N. There's many things which can go wrong - requiring you to restart the process.
Treat it as a D801, as the T-Mobile firmware booted. AutoRec does not root the device. Are you on KitKat or Jellybean? If you're on KitKat, do the following.
You must use IORoot to root the device - it does it in such a way it'll accept custom recoveries.
(You already have the phone's USB drivers obviously)
1) Download IORoot V25 from here.
2) Extract the file.
3) We need to unlock USB debugging, so make sure the phone is not connected to the pc. Settings -> About -> Software -> Tap on "Build" like 8 times fast. Go back into settings and you'll see "Developer Options", tick USB debugging. Now if your device freezes up like mine did when tapping build, then download an app which lets you go directly to developer options.
4) Hook the phone up to the PC, make sure it's not in lock screen.
5) Double click "root.bat" normally (not as admin). Keep going through this process until it brings you to the stock recovery area where you can flash over ADB.
6) It'll walk you through the process where it boots back into Android.
7) Open SuperSU, which it installed.
8) In the settings somewhere, make the grant always accept rather than prompt. My device was bugged not allowing root unless it was forcefully granted like this.
AutoRec - Recovery Install
1) Copy the contents "bumpboot-v1.0-blastagator-signed.zip" and "busybox.apk" and "flashify.apk" onto your device. Download here.
2) Download TWRP for T-Mobile 2.8.6.0 from here, extract recovery.img and copy that onto your device.
3) Copy AutoRec KitKat for T-Mobile here.
4) So you should now have "D801_AutoRec.apk", "recovery.img", "busybox.apk", "flashify.apk", "bumpboot-v1.0-blastagator-signed.zip" on your phone.
5) Proceed to install "AutoRec.apk", ticking unknown sources. Let it boot into recovery. Now reboot.
6) As my recovery didn't stick, install and open "busybox.apk", click install in the program itself. Install and open "flashify.apk", flash recovery, browse using flashify to the location of "recovery.img", let it reboot into recovery. This is where I had to flash "bumpboot-v1.0-blastagator-signed.zip", otherwise I couldn't boot into the OS. So flash that file.
7) Reboot back into the OS. Until we flash lollipop, there wasn't any other way for me to reliably get into TWRP recovery without repeating step 6.
8) Copy over the Bootstack and Stock Rom from here. Don't worry about SuperSU or anything else.
9) Repeat step 6 to boot back into recovery.
10) Wipe everything except internal memory in TWRP.
11) Flash the lollipop bootloader.
12) Flash the lollipop stock rom.
13) Reboot.
14) Now you're able to get back into recovery any time by holding the power + volume down combo, releasing when the screen goes on - and holding it down again.
15) Feel free to flash LineageOS 14.1 or anything afterwards. Make sure to backup your EFS partition at some stage before this - just incase you can't connect to cell towers in the near future.
As you can see, I had to improvise a bit. No guide was good enough to just work in 2017 for my D800. These should work fine for your D801.
Thank you so much for such an amazing and detailed response !!!
After quite a bit more research and work, I got it rooted and got TWRP working.
Once done I uploaded cloudyflex 2.8
Installed it and of course, me being me, chose the wrong install when prompted. It asked Tmobile, other and Canadian 803.
I chose Canadian and after that got back to fast boot.
After that I simply erased boot, aboot and laf, getting ready to restart from scratch but it rebooted on a clean cloudyflex 2.8.
At this point, the phone is running better then stock and I am very happy with it
Your walkthrough is great and I will certainly redo my phone soon again.
For one, practice makes perfect and I certainly like that with your instructions, I will be able to call on the recovery when I want it instead of asking my way into it by adb command.
Thank you again for your time
This community rocks !
Feel free to thumb me. I also have a request for you, I'll PM.
After flashing dirtysanta successfully I wanted to move over to the magisk installation. Following the steps and attempting t use magisk I must have mucked something up very well.
after flashing the initial boot image and twrp from fastboot I hoped that it would fix these issues. Instead it seems to have corrupted fastboot. I did a kdz restore with reset hoping this would help but the touch screen still doesn't work and now I cannot setup the phone to allow adb. Booting from the system menu into usb-debugging mode just boots the phone normally
Currently I can boot into only into android but because I am stuck at the setup screen I can't connect through adb. I am not sure where to go from here.
The only thing that I can think of is getting a usb-otg adapter and connecting a mouse and attempting to allow adb by setting up the phone that way but I still cant flash anything from adb so I wouldn't know what to do from there. Does anybody have any suggestions?
Is there a way to install a boot image without fastboot?
I was very excited to start using this phone and this sucks. Any help would be appreciated
Do u have twrp at all? Some guys used a mouse and got threw the setup with it.
Sent from my LG-H918 using Tapatalk
I can't access twrp at all attempting all methods leads to a normal boot routine. It doesn't even go to the stock page where it asks to wipe data. Just LG logo, black screen (assuming it crashes and restarts), then regular boot
I have successfully restored touch functionality by reflashing multiple different kdz files over and over again.
This has not fixed my inability to enter fastboot. I can enter the default android recovery from the no command screen after using adb reboot recovery but any other command just restarts the phone. Rebooting into bootloader from the default recovery just restarts the phone. I am not sure where to go from here, really upset because any fix requires fastboot

Is this afternoon running step 3 and waiting for boot? Because when I did it I waited around 30 min on the Verizon boot screen before pulling the battery to reboot.
In reference to LG bridge. Is this different than LGUP?

I mean you have to wait at least 30 sec for the step "fastboot flash recovery twrp-3.0.2-1-xxx.img", & also have to do it multiple times in order to load the TWRP successfully.

The strange thing is that I could access twrp for a while but then after restoring with LGUP I can't access even stock recovery. And flashing the notsostock kernel messed up the ramdisk it seems, because it said it couldn't write over it. The thing that concerns me is restoring with LGUP doesn't make any difference to these two thiñgs
I am suffering with a similar issue, VS995s model. The touchscreen stopped working after the TWRP flash, using OTG I was able to access TWRP. I restored both the dec16 kdz and the feb18 kdz with no affect on the screen. I was able to use OTG mouse and bluetooth mouse to reflash TWRP with dirtysanta and used OTG mouse to flash lineage OS v14.1 this did not solve the issue either. I re-flashed stock and am at a loss on the next possible step.
tgtrottier, you mentioned that it worked again after flashing a bunch of different KDZ files, do you know the specific one? I am looking for a useable touchscreen at this point and can deal with no root.
@frownyface
Did you discover the solution to the touchscreen not working? After flashing TWRP I have the same issue.
Nope i used an otg mouse and reverted to stock and returned the item.
I felt super bad about it, but i didnt have the time to invest in disassembling it to find the cause which i suspect was a loose connection due to the extended vibration during the root process.
Thumbs down sorry i could not be any help,
Alright so where i'm at now is basically the aftermath of a failed attempt to install a cyanogen unofficial rom for my phone.
I have a p9 lite VNS-L23 dual sim and well basically, i unlocked the bootloader and i rooted it with twrp and installed superuser using the srk tool. Everything worked fine up to this point until i booted into recovery, cleared cache and data etc to do a clean install and the install failed with an error code 7.
I thought doing a twrp backup before the flash was effective but because it didnt take any length of time, i sort of thought it definitely wasnt a full backup but i didnt pay it any attention and tried to flash it anyway since iv'e never had probs flashing anything with other of the phones ive had before which was my main mistake.
Usb debugging was enabled before trying to flash. I thought it failed because i didnt change my file system but i had no idea how to do that so i avoided it and tried to install a newer version of twrp to see if the rom would work with the updated version instead. When flashing the twrp img file, it asked where i wanted to install and i think i selected bootloader instead of boot cause there were only 2 options.
After than finished and i chose to restart in recovery, recovery never loaded. I was getting erecovery but that couldnt help me either. I was just stuck with no os and a phone stuck on the bootscreen. I tried to unbrick my phone by installing the update file for the international version firmware which i downloaded which was the only one not to fail after trying 2 others before it before realizing the error i was making. I read online that it would restore my phone back to ofw and that was great considering i had no os installed. Now, after the update, i think i reached like 100% then it went blank. I tried to wait a couple seconds to see if it was rebooting but nothing happened. tried all button combinations with and without the charger for varying lengths of time but no luck. I hear a sound when its connected to my laptop tho so idk if that matters. Its a bit frustrating right now and i have no clue how to fix this problem and i havent even had the phone for a long time. If someone. anyone can help me, id more than appreciate it
So far, nothing is responding to anything. No lights, no vibrations and i dont see anything when it conencts to my laptop, my laptop just makes the connected sound. I see Fastboot 2.0 detected but the srk tool cannot detect any emulators or devices :/ im so depressed at this point. More or less just bought the ****.
Sounds bad, try using the dload method and if that doesn't work you are ******.

its the dload method that has me in this mess. It didnt reboot from the upgrade and since then i think ive been in fastboot mode. I get a response with the fastboot devices cmd and i manage to flash the boot, recovery and system of the stock firmware but still no luck. Think my only option is to use dc phoenix but i cant buy credits for that

not getting to the upgrade screen with dload, the phone restarts but nothing on screen. I can use fastboot only to flash and unlock bootloader, check specifications but thats it. I flashed the stock image which is mm thru fastboot but no luck. I read that i might wait for my battery to drain since my battery isnt rly made to be removable. Can i still use dload without any on screen response?
Have you also tried flashing vendor, cust ... partitions ?

Fastboot doesnt flash certain img's such as xloader etc, no vendor img included inside the update but i doubt i'd be able to flash it anyway, but i flashed everything i was allowed to incl. cust, boot, recovery, system, cache, . Everything else is giving error: command not allowed. I've hit a brick wall so far til my battery drains or i take it to a repair shop which is i guess, last resort. Can't seem to find help anywhere on the internet, nothing returns anything to the screen.
Looks like a hard brick, take it to an official repair shop. But remember: unlocking the bootlader does NOT void the warranty.
I think I messed up my PH-1 something royally.
All I was trying to do is unlock my bootloader and load Magisk.
To preface this, my PH-1 seemed to act a little wonky from the get-go. I bought it 3rd person from a guy on craigslist so anything warranty involved I think I'm out of luck.
The phone would take a while to power on, it took something like 10secs on the power button just to turn it on. And if I set it to reboot , it boots into the bootloader. Also, I was never able to access the recovery (even using power + up). It always felt like I had to hold the buttons for way to long to get to its destination; e.g. up and power to get into fastboot.
Ok where I'm at now. In can occasionally get into fastboot mostly after it bootlooping a few times. It won't get past the Essential logo if I try to boot it up.
PS I was able to unlock the bootloader.
Steps I took to remedy this:
> erase all user data in fastboot
> hold power + u + d to hard power off
> follow this guide https://forum.xda-developers.com/essential-phone/how-to/guide-rooting-essential-ph-1-magisk-t3701976
> attempt to install stock system image via flash-all

The issue I was having was a bad usb connection which wouldn't allow me to unlock_critical.

You have to flash magisk in twrp recovery NOT bootloader mode.
It's right in the OP from the rooting guide you followed:
Do not set up a password if you are on 8.1 twrp doesn't work.
You need to read through that rooting guide and make sure you know what you're doing before you try.
This phone is easy to hard brick and there is no solution to recover from that.
OREO 8.0/8.1
REQUIREMENTS:
An unlocked bootloader.
A working ADB/Fastboot environment on your computer. Knowledge on how ADB and Fastboot works is also preferred.
The stock boot image for whatever build you're running/trying to root.
The latest TWRP build for our device.
If on 8.1, remove your pin/pattern/passcode until the root process is done.
1. Download both the stock boot image for whatever build you're running and the Magisk or SuperSU zip. Transfer both files to your device's internal storage.
2. Reboot your phone into the bootloader, then open up your command prompt or terminal and flash the latest TWRP build for the device using:
Code:
fastboot flash boot twrp.img
3. Once TWRP has finished flashing, reboot into your recovery. When prompted, enter your pattern/passcode/password to decrypt your data in order to gain access to your internal storage.
4. Once you're in TWRP, install the stock boot image and then the Magisk/SuperSU zip.
5. Whenever Magisk/SuperSU finishes installing, simply reboot your device! You should now be rooted.
*NOTE: TWRP will NOT remain installed on your device.

I realize all that, the issue is I cannot access any sort of recovery because I think my bootloader is defective.
For example from a cold restart if I press the power button for say 3 -5 seconds it wont boot, just boot to the Essential logo and loop. To get the phone to boot I have to hold the power down for 15-20 seconds while it bootloops a couple times then it'll boot.
Is there a possible way to reflash the bootloader software if it is defective? It's unlocked btw
There is a way to install magisk via fastboot with a patched_boot img which I'm working on. Cant seem to find the right boot img to patch for 8.1
PS Is it possible to flash .zips through fastboot? e.g. custom roms etc
Was finally able to get into recovery, so all is well. Thanks for the help yall
OP, what was your process to successfully get into recovery and fix your problems?
It may help others sometime?

It's really hard to say, my phone has a serious problem with it. sometimes I cant get it to boot, it will boot into the bootloader over and over and over. I've managed to get Lineage 15.1 on if for a bit until I tried to get back into the recovery which sent it manic.
I just got lucky I was able to get into TWRP and flash lineage.
my first issue not being able to flash the stock image via fastboot because I didn't unlock_critical which can sometimes fail when the usb connection is bad.
Currently flashing stock again if my phone will boot up. I'm not sure whats wrong with my bootloader but its causing a ton of havoc

Same boat for me - just keep rebooting to show Powered by Android Screen and then reboot again and again. Was able to see my device using fastboot devices command but all attempts to access recory just repeat the bootloop entry. I would happily check the OEM UNLOCK option in dev settings but can't even get it to book to any OS to make that option happen. Still shows bootloader locked on bootloader screen - any help someone can suggest?
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.

I am in the same boat. I tried to re-install the OS, but because my USB debugging was not enabled, Fastboot worked but ADB would not and since I basically wiped the recovery area, my phone will only boot into Fastboot but will not allow any loading of recovery. I would pay for someone to help. This is so hard to figure out. I have contacted Essential but since my phone is over 12 months old, the warranty has expired.
Help please. It seems like such a waste to have a bricked phone.
I found the instructions on how to successfully use the jasminetool to flash my Trek 2 tablet which worked great and had TWRP installed on my device. Even though I was running B15 I still wanted try out B17 so I used the *.zip TWRP-flashable file to install, and performed a cache/dalvik wipe as well. Immediately after performing this, my tablet stopped booting up completely except for booting into the new recovery menu giving me the option to choose fastboot, adb, factory reset, recovery, power off, or reboot. No matter which option I choose now the tablet always either goes back to this screen or loads the AT&T logo and will not ever boot and remains stuck on this screen. I can no longer even turn off the tablet's screen, and when I try to mount the SD card using the menus it says "SD card not mountable." I'm aware that I can purchase an EDL cable for the Qualcomm 9008 port and possibly flash the stock recovery back on to the unit and then flash either Marshmellow or possibly Nougat back on to the tablet, but I have absolutely no idea how to do this.
Will the EDL cable allow me to actually reboot the tablet back into EDL mode to perform this flash using zadig and/or the jasminetool app? Are there any guides out there that explain how to use the EDL cable in Windows or Linux in order to flash my stock recovery image back on to the tablet? I feel that if I can flash it back on to the stinking thing that I can figure out the rest from there, but I'm hoping that an actual EDL cable will allow me to unbrick this tablet and at least get me back to MM or Nougat and leave well enough alone. Originally I tried flashing the stock B17 image but it kept freezing at the AT&T logo but still allowed me access to TWRP, but after trying the latest builds of AOKP and Lineage none of the firmwares would allow me to boot into Android at all, and after the last B17 flash is when I started to lose access to TWRP or any functionality at all. Some quick instructions on how to use an EDL cable with this particular tablet would be great and highly appreciated. I've RTFM'd but haven't found any solid instructions on how to use the cable to put the stock recovery back on to the tablet.

1. forgot to remove dm-verity
2. There is a specific guide to return stock rom and undo warning menu, but it has flashing stock recovery b15 with jasminetool and install update.zp b17
stock recovery
stock rom
edit.
this is what appears if I am right?

That's correct. The guide I followed mentioned nothing about noverity so it seems that's where my problem is. It boots to that screen and then will either show the AT&T logo or you press a button and it goes into the menu where you can restart, bootloader, adb, reset/power off/etc. and none of the options work. Access to TWRP is completely gone and any option I choose makes the tablet reboot and go right back to that screen. Whoever wrote the guide I used missed a huge step, but I do have the stock recovery file from jasminetool and an EDL cable on the way just in case it's needed since I can't even get the tablet to be recognized in adb when plugged in.

it happens that dm-verity is from android marshmallow and also the developer that created the guide thinks he will use the rom, because the rom of LineageOS and AOKP remove dm-verity without using the file already mentioning, but if he will use stock rom with root you must use the file that you mention

That makes more sense to me than just not including it in the guide. When my EDL cable comes in, I should be able to force the tablet into EDL mode and use jasminetool to return the tablet to the stock recovery image I backed up, and then use fastboot to push the original firmware on to the device or re-install TWRP and attempt to flash a working custom ROM. That makes me feel better about not knowing about the no-verity situation. I've seen the video of someone using a piece of copper and plugging the tablet into their computer and removing it about 5 seconds after plugged in, which forces the tablet into EDL mode just like a physical EDL cable does, and use jasminetool to restore the stock recovery. I will probably do it in Linux this next time around since you need to do some rather wonky things in Windows 10 to run jasminetool and zadig, including booting Win10 into Test Mode to remove driver signature reinforcement.
