Hey guys, I had my V20 rooted, then after a while, I returned to stock. Upon telling a buddy of mine this, he was wondering how I did it, and sure enough my method didn't seem to be known that much. So here's a guide to restore the T-Mobile V20 (H918) to 100% stock.
First off thanks goes to cbucz24 for extracting the TOT into IMGs. Also, thanks to meraz9000 for making that possible.
Ok, first off there is one draw back. You MUST have access to TWRP, or the ability to install TWRP. First you want to download the system, boot, and recovery images. I pulled them from the IMG zip mentioned above and zipped just those three. You can download it here.
Secondly, unzip those onto SD card, or internal storage if you don't have one.
Boot into TWRP. Easiest way is to use ADB "reboot recovery". If you can't do that, hold volume down and power button, and when you see the LG logo, release the power button for about a second, then continue pressing it. Say yes to both prompts and you'll get into TWRP.
Next BACK UP /SYSTEM! This is very important. Whenever you make a change to anything, make a system backup. DO NOT SKIP THIS.
Next, go to Install and in the lower right tap images. Find system.img and choose that, and choose system image. Install boot.img onto boot. Now reboot to system. If it boots properly, go back to recovery and flash recovery.img to recovery. When those are done, reboot to bootloader, and relock the bootloader (for SafetyNet).
You're done!
If you have any questions, just ask.
Please use LGUP and the KDZ file to restore from now on. It is a much reliable way.

Vuciz, so basically you flash system, boot, and recovery images in twrp one after the other, reboot to bootloader and relock the bootloader? Or you reboot after each flash?
What do u mean by relocking the bootloader?
Thank u so much for your help
Only reboot to the bootloader after everything is flashed.
Once back in the bootloader, connect your phone to a computer and run the command "fastboot oem lock". Make sure you have ADB and fastboot installed.
Thank you. That worked perfectly.
It's really good to see that the bootloader unlock is reversable, unlock with the US996 official unlock. I'll be rooting in a few weeks now for sure.
This works perfectly. Thank you!
Quick question, after i choose the system.img do I just swipe to flash from there and not select a partition? Thanks.
I went ahead and swipe to flash but it wont says to select partition but my only options are boot and recovery?
Hi, I got a quick question. When you relock the bootloader, does the triangle go away or does it stay when you boot? does it turn red then?
Thank you,

Sweet. Last question, TWRP stays in correct? I am trying to get stock recovery but I am not sure if I can do that! I know we don't have the proper flash tool yet to do that, but was wondering if anyone here was able to achieve that!

The OP describes flashing recovery.img, so I'm thinking it probably restores after a reboot.
I'm fairly sure that TWRP is overwritten when you flash the recovery.img partition with the stock recovery.img. I didn't try to access TWRP following my return to stock efforts as I was going to warranty repair my V20 due to the blown speaker issue.

Do be very careful with this, I've found from experience that there is no going back from stock recovery if the system won't boot until there is an LGUP dll or equivalent. TWRP is your safety net in regards to everything else going on in development right now, but if you flash the stock recovery and the system decides not to boot, you'll have a paperweight until development catches up. The stock recovery is very limited (VERY, about all you seem to be able to do is factory reset, which likely only wipes the data partition from the speed that it goes through), and fastboot flashing and partition management have been disabled in the v20.
Wanted to do this bit I can't seem to download the files fro m the op

never mind i figured it out
Yeah... what the hell is the point of backing up SYSTEM if you also are flashing the RECOVERY? You won't be able to save yourself even if something does go wrong. Leave TWRP on until the system boots properly. Then go back into TWRP and flash the stock recovery.
Is there any download for the US996 stock?

That's my fault. I thought I mentioned to boot into system fully before flashing the recovery. I'll edit OP.

Hello, I've recently completed the Bootloader unlocking method with Easy Ace Root Tool. Bootloader is unlocked and SHIP S-ON, I need to flash a rom. These roms require S-OFF and have no method to flash them with only an unlocked bootloader and S-ON.
So let me get this straight, us 'low level' and unexperienced users are left without any method to gain S-OFF privileges without following the vague guide provided at tau(dot)shadowchild(dot)nl/attn1/?p=411 Yeah... I can't.
Trying to find alternate methods I have only gone in circles and keep running into old how-to guides. The more I read the more confused I become. I hope someone can point me in the right direction, I would really appreciate it!
Thanks,
Ninjewbag
You don't need S-Off. Flash a ROM in recovery, then flash the ROM zip's boot.img in fastboot.

Good deal, thanks for the reply!
I put the ROM Android Revolution HD 9.0 on the root of my SD card, booted in recovery mode and chose the recovery option, I got the red exclamation mark icon so I pressed VOL up + power button which didn't work so I pulled the battery. I tried all above steps again but this time I was able to successfully get into "Android system recovery <3e> with VOL up + power button. With 4 options:
Reboot system now
Apply update from sdcard
wipe data/factory reset
wipe cache partition
I chose the option to wipe all data, said it could not find Efolder name)'s and "data wipe completed successfully".
Then I wiped cache, then chose the option to apply update from sdcard, it said "Invalid operation" then "success rebooting by reason 00" and proceeded to reboot by itself.
Phone factory reset, I rebooted into recovery again with the same red exclamation mark error. Pressed Vol up + power and back into "Android system recovery". At the bottom in yellow text it says "E: Can't open /cache/recovery/command". I tried another "update from SD card" and recieved error: "success rebooting by reason 00" and reboots.
I don't have a nandroid backup as I read I needed Root to make one, but the phone still works fine as far as I can tell. I don't have a working simcard in it though.
Also from what I've read my eMMC chip may be fried so it looks like I'm retiring early. I'll keep an eye on this thread among others with the same problems.
Cheers,
Ninjewbag
Volume + and power brings you to the factory recovery; you need to use vol - have you flashed a different recovery? If not, flash 4ext recovery through fast boot and try again

You can install the app and then open the app and use it to manually download the recovery zip which you can flash or copy it to your pc and extract the recovery.img file and flash with fastboot. It's a good idea to familiarize yourself wiht the adb and fastboot utils as they come in handy.

Thanks for the reply but as for installing the 4ext free updater version, it wasn't on the market so I used android injector to place and install that APK. None of the options worked as they all give the same error "it seems your phone is not rooted, this option will not function" etc.

Nice! Wasn't expecting to find the 4ext recovery within the adbfastboot.zip. With that I was able to move on, create a nandroid and successfully install a custom rom, thanks! Was a little scared after rebooting, it took around 5 minutes to load past the "quietly brilliant" screen but is working fine now nonetheless.

Glad to help. Wanna hit thanks?
Like the title says, my Nexus 5 won't boot unless I manually plug it in, hold down volume buttons and power, then wait 15 seconds for fast boot to appear, and then select "start."
Thats the problem. Now for some more information:
1. Nexus 5 32 gb
2. ROM: CM 11 Dec 13s Nightly
3. Kernel: Bricked 3.4.0
4. The phone is totally functional. The only thing wrong with it is that it can't reboot. From the system, TWRP recover, or anything, it simply will not reboot. Every time I must go into fast boot then press the power button when it says "start." After this, the phone works just as I would expect it to. I can still flash kernels and backups through recovery, it just must be restarted manually through the fast boot. This is a problem for me because I don't always want to have to plug it in when I want to reboot it.
When did it start:
Let me start off by saying that I thing the root of all my problems was the TouchControl app that allows the knock to wake function to work. I downloaded the app and was told to install the developers custom kernel. I did and not only did the app not work, it also seemed to brick my phone. I was scared, but, after doing some research, I found the method of plugging it in and holding down all buttons for about 15 seconds and my phone was saved. Ever since then there has been the problem. I must always do this to reboot my phone. Since the app didn't work I decided to install the Bricked Kernel and everything went fine except that I wasn't prompted with the interactive installer. The kernel works fine and I am now using the Knock to wake feature built into the kernel and am very happy.
Seems to be caused by swipe2wake aka knock 2 wake aka knock knock (but not totally sure)
What I've Tried (don't assume I've tried something I haven't. I could have missed something obvious.):
1. Resetting permissions through TWRP (just thought I'd try)
2. Putting back CM 11 Kernel
3. Restoring to a time when my phone did restart
Any help would be greatly appreciated. I will try to keep the original post updated with everything I try.
FIXED with the help of jd1639 and meangreenie
------------------------------------------------------------------
1.Follow jd1639's link in 3rd comment to the page and
A. Install adb and flashboot drivers
B. Install your version of factory images from google (if you are running 4.4.2 get the image for 4.4.2)
2. Plug in phone to AC CHARGER and hold down power and volume buttons for up to 20 seconds. This should put it into fast boot mode
3. After getting phone in fast boot mode, plug it into your mac or pc.
4. Out of all the instructions in the "How to flash a factory image" thread go to method 2 and ONLY DO THE FIRST TWO LINES OF CODE. All that needs to be flashed is the bootloader.img
5. After it says complete and your phone restarts you should be able to push "start" on your phone and be good!
I would try and fastboot flash boot boot.img. where boot.img is the boot image from the factory image.

Thanks so much for trying to help. I installed all the things and flashed Boot.img from fast boot, but once I restarted my phone everything was messed up (booted to home screen but basically the system started failing). After this, I retried but deleted my cache and delvik cache. This time the system simply wouldn't boot. Luckily I backed up and restored to my previous version. Thanks for trying, but this did not work.

no it won't delete your data.. but please triple check your files and fastboot commands before executing

Hello,
Yesterday there was an update for the Moto G, I confirmed to do the update. Since then the phone is in a reboot loop. I mean it doesn't matter what ever I do,the phone restart itself in every 2-3 minutes. The phone is rooted.
I've tried to do a factory reset from the setting,however nothing happens when I want to erase the settings. In the bootloader if I chose Recovery or Factory reset,the phone reboots.
I've got a tip that I should remove the update file from the /chace directory,however I don't know how to do so,as the phone keeps reboot itself.
The only place,where the phone is not restarts is in the bootloader.
Is there any way to somehow solve this problem without flash a stock rom ?
Thanks for your help!
Regards,
Péter
The same here. Help!

You have to press volume up instead of power to choose something in fastboot menu.
Unroot and if used custom recovery go back to stock recovery.

However I can't enable the usb debug,as the phone restart faster,than I'am able to do this.
Yes I know I have to press volume up,however if I chose recovery it's reboot itself,so I'am not able to select Recovery from the bootloader.

My is rooted and cwm 6.0.4.6
May be we must do something with fastboot command
my GF's Moto G did the same thing, luckily it was a simple fix.
I had already rooted her stock 4.4.2 and installed CWM Recovery 6.0.4.6.
If you havent installed, CWM or TWRP, then I recommend to do so by fastboot command and the recovery.img.
Here is the forum link to install CWM Recovery for your Moto G:
http://forum.xda-developers.com/showthread.php?t=2563599
So I just Powered Off the phone. Then go back into the CWM Recovery by:
- hold down Volume Down and hold down Power Button for about 4-5 secs
- then let them go and you will see the Fastboot menu
- Press Volume Down (to highlight Recovery)
- then Press Volume Up (to select and go into Recovery, in this case the custom recovery)
- then just Wipe Cache and Wipe Dalvik Cache
- then Reboot Phone.
Done.
I think I will install CM11 for her and not have to deal with the stock ROM that gets official updates pushed onto it causing issues like this.

At the moment i am confused. But yeah i'm assuming it will work.
Cause if i understand it right, the superboot method is a modified kernel.
So you should flash motoboot.img.
There are several ways now. Either you flash cwm and wipe /cache as described above.
Or you flash motoboot and then , in my opinion, it should work.

I used the method to root the phone what is on that site,I followed that description and it worked. I'am not an expert in it,so I just followed PaulOBrien guide,so I can't answer for it for sure.
At this point I'am really desperate as the phone is completely useless, so I don't care even if I had data loss,as I can't access it anymore,nor save it to my PC.
In my knowledge, which seems not to be true anymore, the phone needs to be stock to install any update.
I am not talking about installed apps. It is more about system partition, recovery, kernel and so on.
I would try now to flash the motoboot.img and see what happens.
If this does not work i would flash cmw and try what was mentioned above.
Sure you can go completly stock. But in my view you are not that lost.
I'll stay with you
......but max 5 hours =)

What happens if I try the chace wipe via in command line, I mean:

This should delete the cache right ? Shouldn't this command remove the problematic update file ?
Oh yeah this should be also an option.

I was able to enable the usb debugging,and then to start the bootloader. However If I connected the phone and tried to execute the adb reboot-bootloader command it didn't worked. So I restarted the phone and entered into the bootloader,then I've done the following:
fastboot reboot-bootloader
fastboot erase cache
After the first command,the phone rebooted into bootloader,then the second command finally cleared the chace. Now my uptime is more then 8 minutes,so the phone is working great now
However I will do the complete process on the weekend,but not now as I'am really tired,but I will flash a stock rom at the weekend.

Hello,
I am getting myself deeper into trouble working on this.
First I will explain what I did, I wanted marshmallow and read TWRP needs to be updated to load it and also that that I cannot restore from older backup, so I figured I update TWRP first then do a backup.
I did the TWRP update via app, verified the partition and when done and rebooted to recovery, TWRP was still v2.7 and the phone won't boot, the OS was gone.
so then I figured I flash Dottat M8firmwareandRecovery to get the new TWRP and backed up the Data partition.
then found out that I can't use that Data partition with a different OS. So I figured I flash KitKat back on.
did that, now I can not get back into recovery, holding the Vol down with power will not go to HBOOT.
now KitKat loads, had root, but the dang thing auto updated to 4.4.3 and now lost root. I thought it can't auto update with s-off
so it as asking for another update now and I turned it off. Waiting for someone to help , I keep making it worse.
my phone was unlocked and s-off, I hope it still is, can anything undo that?
Please help

I've personally never seen a device go back to S-ON without the user doing it with the cmd.
That isn't to say it's never happened before.
I'd assume you are still S-OFF.
What happens when you flash a ROM that has a power menu and you select to reboot to recovery or bootloader?
Or you can root and download an app that works the same way. curious what it does.
Also how long are you holding the buttons?
If everything else is working you should be able to get to hboot/recovery - but I honestly don't know.
My suggestion?
Get a more recent RUU .exe and run it on your PC and see what happens.

I would, but I don't know how to flash without the HBOOT, I got some research to do to learn how to do it from the PC.

Download the .exe and click open. Follow directions on the screen. It doesn't get easier, trust me you'll be fine. Wouldn't steer you wrong.

The only time I've seen a phone be a pita when trying to enter boot loader is when it's connected to USB.

My Galaxy Tab2 did that. I tried the M8 again today with USB unplugged, did not get boot loader menu, but then while it was on, I did a Vol up and power (forced shutdown) then while still holding the power button switched to Vol down right when the screen blanked, then I got the boot loader! :victory:

and to correct myself.. one other condition. The older version of software included a "fastboot" option in settings->power that was more like a hibernate feature. That feature when enabled would prevent you from getting into bootloader.

That makes sense, 'fastboot' was on, its now off.
The bootloader works, KitKat OS is working, but not recovery. I get 'Entering Recovery . . .' on white htc screen and stuck there.
I used adb command prompt to flash recovery with fastboot then I tried HTC_fastboot and different versions of TWRP.
tried flashing with Flashify , no errors, it just doesn't load. I think something else is broke.
dottat, do you have an image of RUU rooted Kitkat with TWRP?
Thank you for the help.

Your firmware is too old. That's why the newer recovery won't work. Do you want to update everything first and then RE-root?

Yup , that was it, the older one worked.
So dumped the idea of getting KitKat back and I flashed the Marshmallow custom s-off RUU with TWRP that you provided. so far good now I just need to re-root it.
Thank you
So over the past day I had rooted my oneplus 7 pro and all was going well until I decided to delete the netflix stock application. Then I restarted my phone from holding the power button and pressing restart and then I booted into fastboot. Everytime I pressed start it would send me back to fastboot but I was able go to twrp recovery. Stupidly, I wiped the whole phone thinking I had no other options. Then after that, I found a setting in advanced that allowed me to leave recovery mode I think? Whatever it was, I was booted back into the oneplus start screen and reset up my phone. Then I tried to re-root my phone and couldn't get it to work because it said the magisk zip file was corrupt. Then I just decided to give up and go back to stock.
Little did I no, you are NOT supposed to relock the bootloader, because that is exactly what I did. After doing that, I got a message saying my phone was corrupt and I looked up quick solution and it said to press my volume buttons and power buttons. Now my phone won't even turn on. I am freaking out right now, knowing that my phone is probably bricked and I am going to have to pay probably a third of what I even paid for this phone to get it fixed. When I plug my phone into my pc the device is shown as "QUSB_BULK_CID:0404_SN:3BB285D7". If any of you guys can help, I'm all ears.
edit: I meant I locked oem/bootloader. Also, I got the phone to power on. It is in a bootloop where the oneplus logo shows up and then it gives me the message "Your device is corrupt. it can't be trusted and will not boot"
edit 2: After two hours, I finally fixed it. I downloaded the MSM tool and found the qualcomm drivers and after a few trial and errors, I finally got it to work

U probably should have flashed stock firmware before relocking the bootloader
As long as you can boot into fastboot you should be good. Make sure you have correct drivers etc etc. Boot into fastboot and just boot into twrp, don't flash. Wipe data, system, vendor, dalv, cache. Recheck on what to delete and what order because it has to be the correct things and I might be mixed up off the top of my head, delete them in twrp. Then boot back into twrp after all that and reflash your custom rom. Take note if your ****s bricked you wont be able to install the zip via regular twrp swipe, you will have to use twrp sideload feature with adb and install from pc and install it that way. If that doesn't work at all just do a complete reflash of stock firmware via fastboot. Reflashing custom should work though I got mine out of a brick this way. As long as fastboots working you can get out of anything. Also Linux is 100x better than other OSs for this stuff.

OK here's the order. Boot into twrp, don't flash.
Wipe -> ADVANCED -- select system + vendor -> SWIPE TO WIPE
reboot bootloader
fastboot boot back into twrp
-- then --
Format data, Wipe cache & dalvik-cache
Flash ROM.
Then reboot system. Boom.
Remember you will most likely have to flash the ROM via sideload. As transferring will not work in a bricked phone.
