Hi,
I recently got asked by a friend to flash his google nexus one phone. like a mug i said yes and now i have a issue where it turns on, vibrates 7 times and stays at the splash screen with the x on it. I can boot into the fast boot / recovery mode but nothing works.
this happened after i tried to root the phone, it said waiting for device and didnt do anything so i killed the app (Superoneclick) the phone disappeared from device manager and now wont go past the splash screen.
Does anyone have any idea how i can get it back? .. thanks in advance for any help.

I'm guessing, since you used S-O-C, the bootloader is not unlocked. The only way I know how to fix it is if you OEM unlock it. You'll need fastboot and your Android SDK setup correctly.
Once you have the setup done, change directories to the tools folder, wherever you put your sdk. Boot your phone into fastboot by holding the trackball while powering it on.
Code:
cd C:\asdk\tools\
Plug your phone into USB, and check if the computer sees it
Code:
fastboot devices
Unlock the bootloader (THERE IS NO GOING BACK! You can never re-lock a Nexus)
Code:
fastboot oem unlock
Now you can flash a boot.img and system.img (preferably pre-rooted) from fastboot, and it should boot normally. If the phone boots, the phone is perma-rooted, and won't need any other rooting procedure (you just need to flash a rooted rom). Next time, be a little more careful
Hi wdfowty
at running the risk of asking for more help and making you cross could you post some links to these downloads?
I am a total newbie to these phones and want to make sure i have the right apps.
thanks again for the help and the quick response... and if i manage to get this phone back believe me it will be the last one i try to flash !!
cheers

Nah, you've got me wrong. I'm all about helping people that are willing and able to be helped.
Follow this guide, it'll walk you through the steps to set up your sdk and unlock the bootloader. The guide is a little dated, so the info might not be 100%, but it's generally everything you'll need to know. If you get stuck, feel free to ask.
Hi again,
when i run the command fastboot devices i get an error AdbWinApi.dll is missing.
it tells me to reinstall the app but i have done that and also run all the updates and i still get the same error?
Interstingly i also get the phone to fastboot and it says in red text on the phone fastboot.usb but i cant see anything in device manager that says Nexus one etc?
any more help appreciated.... worst case you dont fancy a christmas break over in England do you?
cheers

With the latest version of the SDK tools, they changed the directory for adb and fastboot. Unfortunately I'm not on my Windows machine... but check in the directory where you have the SDK extracted to and look for a platform-tools directory (iirc). From there, you should see fastboot.
So basically where it says this "Type: cd C:\android-sdk-windows\tools" change it to "C:\android-sdk-windows\platform-tools". Keep in mind that directory name may change... again, I'm not on my Windows machine right now.
Hi again,
thanks for the continued help. I have managed to get past that, i have OEM unlocked the phone and managed to copy the flash image to the device using the commands in the link you sent me.
problem i have now is when i go into recovery the phone again just pulls up the splash screen and vibrates 7 times.
i believe what should happen according to the link is to follow the 6 steps below.. even i can do that, but the phone doesnt get that far
//Turn phone off -> Hold Volume Down, hold Power button
//Press Volume Down to highlight Recovery -> press Power to select Recovery
//Backup/Restore -> Nand backup
//Wipe -> Wipe data/factory reset
//Wipe -> Dalvik Cache
//Flash zip from sdcard -> alpha-r##-update-modacocustomrom-nexusone-desire-withadditions-signed.zip (Or whatever other ROM you're using.)
another point is it runs a couple of lines of blue txt relating to the sd card, but it flashes up and dissapears too quickly for me to be able to read it and send across to you.
thanks again and if you can work this out i owe you a beer !!

Have you flashed the recovery image using fastboot, or did you only copy the recover image to the sdcard? Step IV in that guide.
It sounds like you need to reinstall your recovery.
Download the recovery found here: http://forum.xda-developers.com/showthread.php?t=611829
Rename that file to recovery.img and place it somewhere you can remember
Boot the phone into fastboot by holding down the trackball and pressing power button.
Code:
fastboot devices
Code:
fastboot flash recovery C:\path\to\recovery.img
If all went well, there should be no errors. On the phone, use the volume keys to select "Bootloader". It will take you to a white screen with the blue text (ignore it, it's looking for update files like "PASSIMG.zip"). Select recovery, and it'll boot into recovery. If you see menu items, you are good!
I ran the fastboot command and used the flash image ending 2.0.0
this is driving me round the bend !!
What happened when you used the fastboot flash command? Did you see a bar on the top right of the phone?

i do that and it accepts the recovery file and the progress bar goes up on the right hand side and the cmd prompt says its all good. then when i select recovery the phone goes to the black background with the four coloured cross and the unlocked padlock, vibrates 7 times and just hangs on that screen
beleive it or not it booted up a moment ago and the phone worked like it did before with v2.2 on it. so i am happy now it can be recovered... i just dont know what to do to straighten it out!
yes. the bar goes up on the right hand side of the phone. and i have definitely unlocked it as it now says unlocked at the top of the menu.
Have you tried to reimage the phone with the passimg method? Directions are provided in the wiki, under the unlock/restore heading:

Follow PASSIMG method (filename is case sensitive).

There's no exploit that has been found yet to S-OFF your HBOOT 1.16.0000 Incredible S, but you can unlock the bootloader, flash a recovery image, and install a custom ROM.
If you're not sure about doing this, I'd advise against it - things can go wrong, and there is a chance you'll damage your phone. Also be aware that HTC's unlock process effectively voids your warranty, and it will erase everything on your phone, as if your stock ROM went back to how it was when you first bought the phone.
1. Go to http://htcdev.com/ and create a free account. Once done, click the "Unlock Bootloader" link, or click here. Note that the Incredible S v1.16.0000 wasn't listed at the time of writing this, but the process still works fine.
Follow the instructions there to the letter; it's a pretty simple process - the guide says you'll need HTC Sync installed, but you may just need USB drivers. I installed HTC Sync for this process and then uninstalled it from my PC afterwards.
Part of this process involves grabbing some files from the Android SDK; you might not have that installed, so download them HERE. Put them somewhere easy to find, like the root of your C: drive in a folder called "android" (I'll use this for the rest of the instructions).
2. You'll know the process is going well when your phone flashes up an image asking if you're sure you want to unlock your bootloader. If you're still sure, select yes, and the process will complete.
3. Once done, your phone's bootloader will be unlocked, enabling you to flash a recovery image.
4. Go to here and download the recovery image for the Incredible S. Put it in the "android" folder along with the other files needed for HTC's unlock process, above. This file is the ClockWorkMod recovery image for the IncS.
5. Shut down your phone. Plug it in via USB to your PC which you set up during the HTC unlock process. Hold volume down, and press power and the phone will boot into the bootloader. Wait for it to scan your SD card (takes a few seconds), then ensure "Fastboot" is highlighted and press power.
6. On your PC, load up a command prompt - open the Start menu, go to Run, and type "cmd".
7. In the command prompt window, type the following, assuming the HTC unlock files and the recovery image you downloaded in step 4 is all in C:android.
Code:
cd c:android
Then type:
Code:
fastboot flash recovery <recovery_name.img>
Don't forget the .img on the end, and replace "recovery_name" with the specific name of the recovery image you want to use. For ClockWorkMod linked to in step 4, you'd type:
Code:
fastboot flash recovery cwm-4.0.1.4-vivo.img
After a few seconds, ClockWordMod will have been flashed to your phone.
8. Reboot your phone, there should be an option in the fastboot menu (volume up and down to navigate, power to select). It should boot as per normal. Put it into USB disk mode, and download a ROM that you'd like to use. CyanogenMod is a good start: http://www.cyanogenmod.com/devices/htc-incredible-s
Download the ROM and place it in the root of your SD card (ie. not in any folders or anything).
9. Power off the phone. Hold volume down and press power to boot back into the bootloader. Use volume down to select "Recovery" and press power. ClockWorkMod recovery will load.
10. Using volume up/down and power to select, go down to Backup/Restore. Select it, then hit Backup. ClockWorkMod will backup your stock ROM in case there are any dramas and you want to go back to it.
11. After that (takes around 3-4 minutes), go back to the main menu. Select wipe data/factory reset and confirm. Go back to the main menu, select Advanced > Wipe Dalvik cache > confirm. Always best to do these 2 things before flashing a new ROM.
12. Go back to the main menu, and select "Install zip from SDcard". Next choose "Select Zip from SD card" and select the ROM you'd like to install. Confirm this action, and ClockWorkMod will install your new ROM. After that's done, shut the phone down.
13. Ordinarily you'd be done after that, and you could boot into your new ROM. However HBOOT 1.16 does some weird stuff and tends to cause issues; I think it interferes with the installation of the boot.img that ordinarily would be flashed with the ROM. Anyhow, grab the ROM that you downloaded earlier (CyanogenMod, in my example), and on your PC, unzip the file somewhere. Once unzipped, inside you'll see a file called "boot.img". Put this in the same folder as your other Android tools that you used earlier. Power your phone on, hold volume down, and instead of loading recovery by choosing "recovery", choose "usb fastboot".
14. Open up your command prompt again (Start > Run > "cmd"), and type (using the "android" folder for this example):
Code:
cd c:android
fastboot flash boot boot.img
This will flash the boot.img to your phone.
Power off the phone, reboot it, and you should be good to go. There may be more efficient ways to do some of the above, but I'm not a massive guru at this stuff, I just haaaate Sense and bloatware. If any gurus notice any errors, please let me know.
* Edit: Bear in mind that by default, a CM7 install won't include any Google apps (this includes the market app); this needs to be flashed as a separate update via recovery. At the time of writing, a link to information about the Google apps package for CM7 is here:
http://forum.xda-developers.com/archive/t-1297579.html
Have updated the title as this should work with HBOOT 2.00+; haven't tested this myself though.
Apologies, not around this site too often these days, at least until an official ICS ROM is out, so I probably won't respond to PMs. Good luck, and hope the above info helps - but it may pay to do some due diligence yourself first, in case it's out of date.

I second that. Great job. Thanks for your contribution.
Excellent job Lynt, I will try this later...
Yeah good work dude. Should put a stop to the constant h-boot posts. We just need a mod to sticky this.
I bought one XTC Clip to unlock Incredible S but now i'm Xperia ARC.
If someone wants buy my XTC Clip, contact.
I sell by one lower price.
After flashing the boot.img, you may need to install the ROM one more time (if the phone cannot boot). But this time, do not wipe any cache. Just install the ROM from Recovery.
I wanna do that but i am afraid that i may end up making my device useless

You dun learn when u dun try. Go ahead, it's quite safe if u follow the steps carefully. You will be glad if u did. The custom ROMs are way better than the stock ones.
thanks mate! works perfect!
just need to add a little bit steps u were missing
after step 12, have to restart the phone to fastboot in order to flash boot.
another question, if i flash a custom rom, will it unlock my sim lock as well?
i cant find it out just bcos i already unlock my IS by purchased a unlock code online 3 weeks ago.
many thanks
and thanks and thanks again!

No flashing a custom ROM will not SIM Unlock a phone.
i heard some dude downgrade the HBOOT to 1.13 by using gold card.
i tired, but IS checked version somehow, said version is old.
can we flash UUR instead of flash a custom Rom? and if it works is that mean Hboot will be 1.13?
i tried before, got an error says unable to open the file. any ideas?

Hello today I attempted something that I thought was going to be a quick video tutorial fix. I tried Rooting my HTC one. I followed several guides and read many posts I easily managed to unlock my phone. The problem started when trying to flash the recovery onto my phone, first I tried through commands: fastboot flash recovery and I received the error (FAILED data transfer failure unknown error) I've searched for 7 hours looking for a fix. Since I cant root reverting back to a fresh install is impossible, I cant find a RUU for telus, (I live in canada). I just don't know what to do, when I try to flash anything my bootloader freeze, drivers are up to date, tried restarting computer. Used One_M7_All-In-One_Kit_v1.0 doesn't work. This is a nightmare come save me before I jump off a cliff.
EDIT: What I did from beginning was followed this video "How to Root the HTC One-FlamingArio"to the point where you try and flash the recovery fastboot. That didnt work so after trying to fix that I tried How To Root HTC One & Unlock Bootloader - Easiest & User Friendly- The smoking Android ( super boot a 1 click install) that made my bootloader screen turn to tampered. after that I tried One_M7_All-In-One_Kit_v1.
Note in all in one kit I did erase cache and standard recovery works fine, I've re-installed it may times.
Cant post links yet but I gave video names.
EDIT: when I do the cmd fastboot devices my device shows up when I do adb devices nothing shows up could this be part of the problem?
Thank you all for your help, I re-installed all the programs on my laptop and redid all the steps and it worked. Bye!
Try this in ABD fastboot erase cache then flash the recovery again i hope this helps:fingers-crossed:
What did you do from the beginning? Could you post a step by step traceback of what got you to this point? Let's see if you missed any steps

Keep an eye on this thread http://forum.xda-developers.com/showthread.php?t=2302870
Many people are looking for the Telus RUU.
Can you still access standard recovery? If so try reverting to factory settings (all data will be lost) and try to boot.
If you can get it to boot you should have more luck in trying to root your device.
I know that I had some issue's trying to get root on my device. But once I got S-off with revone, I was able to install root no problem.

Nice to see you sorted it
Assuming you have actually flashed a recovery image to your device, you will then need to push a ROM to your sd card so that you can flash it in recovery.
Just do the following:
1. I am guessing you have the HTC drivers installed on your PC.
2. Download the attached adb.zip and unzip it to a folder on your C drive and call the folder whatever you like.
3. Boot your device into recovery and plug it in to a powered USB port on your PC.
4. Navigate to the folder that you just created on your PC and copy your ROM zip into it. rename the ROM zip to 'rom.zip' to make life easy.
5. Inside the folder, press and hold the shift key and right click in a blank part of the window and select 'Open command window here' (screenshot attached).
6. Type 'adb push rom.zip /sdcard' (don't use the quote marks)
7. Press 'enter'
8. Once the zip has finished being pushed to your sdcard, you can reboot into recovery and then flash it as normal.
EDIT: That will teach me not to read to the very end of a post. I'll leave this here for someone else.
************
First, I am not responsible if you damage your phone in any way.
Also you might back up your phone's data completely because after unlocking bootloader you can lose all your installed data.
*************
So, first step is unlock the bootloader. First go into
Setiing> About Phone > Press Build Number A couple of time until it shows you are a developer now > go back > Developer Options > Turn on USB debugging.
After that, go to your bootloader, by powering off your phone and once it is powered off press the Volume down key + Power button until something appears with a vibration.
Now download adb and fastboot from this link:
http://*******/1Zsyme
After downloading it, install it. And you can install it easily with no problem. Just make a folder in your windows drive of :
C:\Android-adb\
And you are good to go.
Now goto that folder (C:\Android-adb\) and press SHIFT+CTRL+RIGHT-CLICK together or just SHIFT+CTRL first and then RIGHT-CLICK and then click "open command window here".
Now connect your nexus 5 and check if your PC makes a sound like when you connect a external device.
If yes, then you are good to go. Else try connecting it several times to automatically make the PC install any drivers.
After this, go to that DOS type window and write:
fastboot devices
(press enter to activate any command)
If you it shows a serial number then you are doing fine.
After this, write this command in that CMD.exe window:
fastboot oem unlock
and wait until something pop-ups in your phone. It might be a warning, read it carefully and using your volume up or down key cycle through the options and using power button select yes. And it might reboot on it's own else restart manually by pressing the power button for 10 or 15 sec until you see your screen with a unlocked lock which means you have successfully unlocked the device.
Now after that, it's finally time to FLASH recovery file.
For this to happen you need to download CWM latest version from here:
http://*******/1Zt1Fs
It's latest for HAMMERHEAD or NEXUS 5!!!!
Now, again go to the bootloader as described in the beginning.
Now you can also copy the recovery zip file by your data cable of your phone by turning in on normally and also from bootloader.
How to do it from bootloader? Here's how too.
Now you have to be on the bootloader screen. Now goto the same CMD.exe and write:
adb push filename.zip /storage/emulated/0/
adb push filename.img /storage/emulated/0/
If you get any error ask me.
Now it might get some time to be moved to that.
(Data Cable should be attached to do so, also the RECOVERY img file should be in C:\Android-adb\ this folder to be moved to PHONE)
Now, you might have successfully moved the zip file to your phone. So now write this command to flash Recovery.img file:
fastboot flash recovery your_recovery_image_name.img
After this, it will FLASH the recovery file. Until it's installed successfully wait till then.
Once it is FLASHED, now cycle to recovery mode using volume buttons from the BOOTLOADER and wait till it gets there:
Now you will see some options, but you need to flash a zip file so cycle again using volume buttons and select anyone using power button. So select:
install zip
Now select choose zip from /sdcard
Now you are in your internal storage's directory where you moved your zip files from CMD.exe. Just select it and you are done. go back and reboot system now. And you are done.
Don't forget to say thanks if you find it helpful in any way.
Also report to me if you get any errors between in it. By the way, I didn't have any errors in my journey to do this in first time.
You should point out and highlight that unlocking the bootloader will wipe all data.

You do not need USB debugging for fastboot, you do not need to open fastboot or adb within the directory they are install in, you...
There are already guides, which are more accurate and up to date, to direct people through the process. Who uses CWM?

TWRP not worked for me. I use and recommend CWM. TWRP is full of bugs and does not show errors and hangs. But CWM is the best.

Thanks. I did mentioned but didn't highlight.
Except for the fact that CWM is out of date and not maintained for our device.

What is the point of this thread? Isn't this all common knowledge?
Google says you need to hold VOL UP, VOL DOWN, and POWER to boot into fastboot, but I've used just VOL DOWN and POWER on my N5.
fastboot oem unlock has been superseded by fastboot flashing unlock, though it still works for the N5.
You can download the Android ADK CLI tools from https://developer.android.com/sdk/index.html . Always point to the authoritative source.
You'll need to be in the \platform-tools directory UNLESS you add it to the PATH.
So far's I know, ADB will not push a file while you're in fastboot. You can just flash the recovery file from the directory you have it, e.g. fastboot flash recovery .\your_recovery_image.img.
Very nice of you to post, OP, but you've got a few things wrong in your guide. Read some others to find your errors, and keep writing, Android needs informed enthusiasts and writers.
Yeah, it's 2016. Why was this thread even made? It's either common knowledge, or there are a hundred other guides about doing this.
Plus, who the hell uses cwm these days? Twrp or don't waste your time.
This whole post feels like something from 4 years ago.

It's outdated, no updates. Last I heard some of the CWM team are now contributing to TWRP. It's pretty much the official unofficial Android custom recovery at this point. You will also have a lot of issues trying to flash or update on older versions of TWRP or other recoveries that aren't updated due to file structure changes in newer Android versions.

I see the light. CWM team seem to have abandoned Helium, too; no longer works on systemless root. That's second or third app they've simply gotten bored with and not continued development.
Note : This guide is for H-81120-I & H-81120-O the latest update any firmware version below it will cause hard-brick so be careful before attempting anything, i wont be held responsible.
As a user with less knowledge about Commands and all, i was searching for answers by reading threads here and there and found my answers though some time tricky and sometimes easy.
Also in reading those threads i found many fellow members stumble upon resulting Soft bricks and in some cases a Hard brick or can say making their beloved G4 a paper weight.
So i thought i must put some really easy steps in order to clearly guide people like me who are too noob to understand the sophisticated developers steps.
Another reason for this Thread is also i saw many people asking about how to etc after updating to 20-O update for our H811 MM.
Few things to Prepare before Start
1- Properly Install Drivers for your H811 Variant of G4, cant find them Install LG Bridge.
2- Read the Whole thread before starting anything.
3- Confirm that all requirements are full filled and your variant is capable of everything mention in the OP.
4- Enable Developer Option then inside it enable OEM unlock and Usb debugging.
5- Always use Command prompt as Administrator.
6- Make a folder name G4 and paste all the file required for the unlocking in it for easy access and remembrance.
7- For Safer side after unlocking the bootloader boot into TWRP from fast boot and do not install TWRP.
8- Flash your SuperSU after that boot into android and see if all works.
9- Again Via Fastboot boot into TWRP make a backup of everything working fine. Boot into android.
0- Again same Via Fastboot boot into TWRP and now install your TWRP image via TWRP install function. So if by any means this is the culprit you can still revive your phone via your backup.
Attachments to Download
1- Adb Package can be found Here.
2- Download the latest TWRP.img 3.0+ from Here . This file needs to be on your computer and external sdcard.
3- Download the latest SuperSu zip (2.67+) from Here [Thanks to Chainfire] and stick on external sdcard as well.
Since downloading is complete now simply unzip the adb folder (containing fastboot by default) and paste both the TWRP image file and SUPERSU zip inside it.
Now Hold Shift and Open Command prompt here.
1- Input command to see if your device is visible in ADB.
Code:
adb devices
if you see your device and the status is off line then there will be a prompt on your G4 screen waiting for approval, accept it and input same command now all will be fine.
2- Now input below commands one by one. ( All credits to Autoprime )
Code:
adb reboot bootloader ( This will reboot your device to Fastboot mode )
fastboot oem unlock ( This will wipe all your data )
fastboot getvar unlocked ( This will check your bootloader status: Should be successful )
fastboot boot twrp-3.0.2-0-h811.img ( Phone boots TWRP ) Please put the full file name with .img extension or it wont work.
3- Now the Phone should be in TWRP install SuperSU from there which you have already pasted inside your external SD card.
4- Reboot to system and see if SuperSU is installed. In some cases First flash of SuperSU does not work if your case is same the again boot to Fastboot and from there boot into recovery, since your bootloader is unlocked no need to repeat the unlock OEM command.
5- Now for safer side follow the steps 7, 9, 0 mention in Preparation heading above.
Hopefully all will be in your favor.

I know several guides are available for same purpose so if any body finds it offending any rights can ask the moderators to remove this thread. The purpose only is to guide simple people like me to save their devices from getting bricked.
As by reading the thread many people are falling for permanent TWRP installation as its mention in the OP anyways for people not getting permanent Recovery follow below:
Boot to TWRP from fastboot Bootloader
When recovery comes up click Install >>>> then in the right below corner you ll see a tab for IMAGE >>> press it browse the recovery IMG which you stored in your SD card >>> swipe to flash >>> From asking where to install >>> select recovery >>> DONE.

Indeed needs to be in both but needs to be in the same Folder as Fastboot file, if not wont work.
beside will be cool if you add a NOTE about if they are in 20o they must stick with 20o base roms, if not they'll get Hard-Brick.

Guys,
If I read it right:
LG G4 must be on 20o (stock) to follow this instruction.
If it’s on 20i or below, it must be updated to 20o (OTA or whatever) first!
It might be obvious for you, but not for me.
Again, but better be safe, then sorry.

Thanks for clarification. I’d change 1st post a bit:

0. LG G4 with 20o (stock) firmware.
When I do adb reboot bootloader it just boots me back into Android... shouldn't it take me to the Fastboot screen?

Nevermind, I forgot about OEM Unlock...
thanks for the write up
This is not specific to 20o. It's the same steps we've been using all along. Nothing new to see here.

problem with fastboot
Thanks you for helping:fingers-crossed:
problem with fastboot
Hi,
I am a newbie in xda. I am trying to root and install TWRP into my lg g4. I am using software version H81120o. I checked enable OEM unlock and USB debugging. I have downloaded lg driver though lg bridge and all the files from the post. However, I got two problem while installing the twrp-3.0.2-0-h811.img.
1st problem (stuck here and need to reboot also not showing h811 on "the list of devices attached" after typing command "adb reboot bootloader"):
C:\Windows\system32>adb devices
List of devices attached
LGH811xxxxxxxx device
C:\Windows\system32>adb reboot bootloader
C:\Windows\system32>fastboot oem unlock
...
FAILED (remote: Already unlocked)
finished. total time: 0.012s
C:\Windows\system32>fastboot getvar unlocked
unlocked: yes
finished. total time: 0.004s
C:\Windows\system32>fastboot boot twrp-3.0.2-0-h811.img
cannot load 'twrp-3.0.2-0-h811.img': No error
2. 2nd problem(stuck here and need to reboot):
C:\Windows\system32>fastboot boot twrp-3.0.2-0-h811.img
< waiting for device >
I checked online this problem might do with driver not up to date. Under device manager, my lg g4 is recognized under android device with android bootloader interface.
What should I do now?
Thanks you for helping:fingers-crossed:
This Root-Method worked like a charm... The only issue I'm running into is for the TWRP recovery to actually stick. When i manually reboot into recovery I get the little android guy with his chest open and the red triangle with the "!" in the middle.....am I doing something wrong by any chance??
I did everything but can't seem to get TWRP installed
Thanks a lot for this write up. I have been trying for about 2 weeks to root my g4 and it worked finally, So many thanks to you

same problem here but I just now got it working...sort of . I still can not make anything come up except the factory data reset when I use the phone volume and power button.
I thought it might be just that I wasn't coordinated enough so I downloaded this small app to do a recovery reboot.
After I installed the app and used it, I got the little android guy with his chest opened with the red triangle. I took out my battery, put it back in and booted my phone with the power button.
I then connected my phone to computer via usb and went back into adb and opened TWRP and installed the twrp-3.0.2-0-h811.img again but this time I looked around a little more first, and noticed a setting to either install in boot or recovery partition. I selected recovery partition (neither were selected) and installed it. Now I can boot to TWRP recovery with the app I installed but still nothing but factory data reset with the volume and power buttons. I can live with this for a while until I can maybe find a solution.
I had the same issue but when u get into twrp make sure the IMG is in your SD card and to permanently have twrp installed go to home and press install.. Choose from image and install hope this helps

In regard to booting into TWRP recovery with just the power and vol buttons, I just read this on another thread:
It boots into what appears to look like a default LG G4 factory reset page. For me, i clicked reset, and then yes, and surprisingly it brought me to where i wanted to go. TWRP Recovery.
I tried this and it worked for me as well.
I had been there before and tried it and it did a factory reset after I had spent an hour or two tweaking my phone, I was not a happy person. This time I did feel almost positive I had TWRP installed correctly and did not have nearly as much time spent getting things set up like I want them on my phone...It was still scary pressing that reset button and yes button.
If you don't have TWRP (or maybe some other recovery) installed it will factory reset your phone. I just thought I would share this and what happened with me. Do it at your own risk.
