Hello,
I come here and make a new thread after I spent the day inside various forums to solve my problem but wasn't able to.
Here is the thing I tried to install the cyanogenmod earlier today. I unlocked my N1 properly and think I rooted it properly as well. But I was unable to install the custom rom. Actually my N1 won't even boot, it's stuck on the cross image with the unlocked lock and I can't boot the recovery either. I tried to install a custom recovery, the amon ra thing, but it still freezes on the cross screen.
I assume my N1 isn't completely bricked since I can still power it up, start the fastboot mode and my computer recognize de USB connection (however ADB won't find the phone even after I re-installed the drivers).
So here I come for help to either bring back my N1 to its former stock rom or any functionning rom.
Thanks.
Try the unroot/restore guide with PASSIMG of FRG33. Look at my signature.
oh thank you !!! It worked perfectly !
EDIT : Well spoke too soon I rebooted the N1 after its apparent recover and it froze again, so I started the operation once more and while updating the files ravio_v2 was checked "fail-pu" instead of "ok"
EDIT 2 : Well I rebooted after the update and the N1 never powered up again ... I guess now it is really bricked... though I can't figure why

You can't even get into fastboot any more?
Also, you say you followed the right steps to unlock the device and the right steps to root the device... What steps did you take exactly?
Hi,
to unlock the phone I used the oem command in the fastboot mode. Then I tried to install the amon ra custom recovery and I think that is what brought all this trouble.
Can you still see your device through fastboot? If so you should be able to flash a recovery image and a ROM of your choosing.
It should boot up fastboot like Dirk said. You can not brick the phone by flashing a recovery.

I guess there is some HW fault - might be a recent bad sector in one of the system critical areas. It's not something you can cause with SW - unless you're flashing hboot or radio, which should have been covered in the first restore attempt, which worked.
Anyway, if it doesn't power up at all - and doesn't react to charging - try pulling out the battery for several hours, and then put it back and try again. If it doesn't work - then you're up for a warranty repair...

No the phone doesn't boot anything. I'll try to remove the battery and wait a few hours like said above, if it doesn't work I'm still under warranty I think
Hey there.
I flashed a new ROM (Kaos Droid 7.0.0) and the fitting gapps some minutes ago from CWM Touch. Everything worked as supposed, no errors, no warnings, nothing. Then I rebooted the Nexus 7 and now it's stuck in the worst bootloop I have seen so far:
The Google Screen appears, stays for some seconds, then I see a screen with the CWM Logo and the text "ClockworkmodRecovery 6.0.38", after this the device seems to reboot and the sequence starts from the beginning again.
I can not get into recovery, I can connect to my PC via USB but connection and disconnection happens every few seconds (because of the bootloop).
I guess that's it for my Nexus 7 or does anyone have an idea what I can try to do. I'd be really thankful.

Hi, Jagutherrschaften...
Try pressing VOLUME DOWN + THE POWER ON KEY and HOLD BOTH for 30 seconds (or as long as it takes to break out of the 'bootloop').
(or BOTH VOL KEYS + POWER ON if the above doesn't work... although it should).
Keep them pressed until you boot you into the bootloader....
You should now be free to run fastboot commands, to either fastboot flash back to factory stock... or you could attempt to just boot into recovery, and maybe do a Nandroid Backup restore from your previous setup (assuming of course, you created one).
Anyway... as long as you can still access the bootloader... all is not lost.

Sorry, I forgot to mention that I can't boot into bootloader. I tried every single combination of keys. The bootloop goes on and is completely unimpressed by my keypresses. Bad bad thing.

How fast is the bootloop? and how long are you pressing the buttons for?
Lean on them, as it where, for a good minute or so... the device has to pick up the 'interrupts' sooner or later.

Thank you for your answers. I tried every combination and kept the keys pressed for 2 mins. Nothing. The only thing I can actually do is shut the device down by pressing POWER + VOL UP for a long while.
If bootloop doesnt stop and you cant get into bootloader....then just long press power button..that should stop the cycle...and then volm down plus power button....should get u into bootloader..atleast worked for me..

Mmm... this is a strange one...
Just had a look a your video... and I've seen a few bootoops, but never one involving a Custom Recovery and ONLY the Bootloader Unlock screen (yes, that is the Bootloader - it's just not normally recognized as such, because it's not in FASTBOOT mode).
If you've shutdown the tablet by pressing VOL UP + POWER ON, you've effectively booted the device into APX mode (it looks like it's shutdown, but it isn't) - if it is in APX mode, the device is now awaiting for you to run some nvFlash commands, which currently can't be done (though there is now, a very specific exception, which is not applicable here).
I agree with the previous poster, @neo45215, VOLUME DOWN (hold), then POWER BUTTON, (whilst still holding VOLUME DOWN), should boot you into the bootloader... but I think precise timing is required. Please read the following, carefully, several times.

QUOTE from http://forum.xda-developers.com/showthread.php?t=2133986
"Starting from booted or boot-looping OS:
Power (10-15 seconds) -> Normal OS Boot**
** Bootloader Interrupt: In any of the cases where you hold the power button down to try to break out of the current operating mode, if you press the Vol-Down button right after you first see the black and white screen with the Google logo, the tablet will proceed immediately to bootloader/fastboot mode, rather than booting the normal OS. You need to be ready though - you only get about 1 or 2 seconds to do this! (Thanks to RMXO for pointing this out) Note that this means you can get to the bootloader directly from any other mode!
This also explains why, when attempting a cold start using Vol-Down + Power, if you accidentally let go of the vol-down button when the screen first lights up, the Nexus 7 will boot to the normal OS. In this case, pressing Vol-Down initially is actually superfluous - what makes the device go into bootloader/fastboot mode is the Vol-Down press immediately following the google splash screen - there actually is no unique "Go to fastboot from a cold start" method."
----------------------------------------
I'm at loss to suggest anything more helpful... this looks like the bootloop from hell! But I'm convinced, that with the correct timing and persistence, some key-combo interrupt could break the Nexus 7 out of it.

Thanks a lot for your help, I have tried everything, I can't get anywhere... neither bootloader nor recovery.
Additionally I can't make the device do anything I want by adb.
And as a "bonus" I can't send my Nexus7 to repair because this stupid bootloop shows "ClockworkMod Recovery v6.0.3.8" :silly:

Really sorry to hear this... it is baffling:.
I've been hanging around on XDA since January, and I've come across a lot of weird behaviour, reported by other posters. But this is something that is outside my experience.
A few questions... (no guarantees, but I'll try to see if I can come up with something)...
Can you post download links for EVERYTHING you've flashed...
The ROM, the Gapps, the CWM recovery.
Also, what order did you flash them in?
Did you use fastboot? or a Toolkit at any time?
Where you rooted BEFORE you embarked on this endeavour?
How did you acquire root?
How long have you had the Nexus 7?
Is it a WiFi only model or a WiFi and 3G model?
Have you flashed any other Custom ROMs prior to this one?
If, so, any problems?
Do you know your current bootloader version number?
What was the battery status (percentage) prior to you flashing this ROM?
Sorry for all the questions... but something, some tiny litlle detail, might set a 'eureka!' light bulb off in my head.

OK, I'll try to answer as detailed as possible:
ROM KaosDroid7.0.0
FittingGApps
CWM Recovery (Touch) was installed through ROM Manager Premium
The order of what I did was: I made a backup in Titanium Backup Pro, then I made a nandroid backup by ROM Manager Premium. I went to recovery, wiped /cache and /data, then flashed KaosDroid7.0.0, flashed GApps and rebooted. After my Nexus7 had fully booted I restored some user apps and settings via Titanium Backup Pro. I had to reboot. After that I explored that clock was force closed whenever I tried to access the alarm clock. I wondered if I could possibly have overseen a checkmark when restoring with Titanium Backup Pro (maybe forgotten to untick a system app or setting) which could lead to the force close. So I decided to start over again.
This time I thought about using ROM Manager Premium for wiping and flashing. I started the app and it told me there was an update for CWM Recovery. So I installed this update through ROM Manager Premium - CWM Recovery Touch 6.0.3.8. I rebooted and went to recovery to flash ROM and GApps again the normal way. Before flashing I wiped /cache and /data again. Everything went fine until I rebooted the tablet and found myself in this "bootloop of hell" as you called it... After having tried a lot to break it, I opened the Nexus7 to remove battery for the first time.
OK, now the other questions:
I bought my Nexus7 about 11 months ago, it's the 16 GB WiFi only version. I aquired root by using this Toolkit and everything went really smooth. I tried several ROMs yes, after some time I came across KaosDroid (don't exactly know which version I started with, maybe v5.0.0) and really liked it. I flashed a new version whenever there was one and never had any problems before.
I am not sure about my current bootloader version, I have some not too long ago nandroid backups on my PC, can I find out anywhere in there? About battery, it was 55 % or so before I started flashing, maybe even more.
The way I see this is: It looks like ROM Manager has messed something up. I have never seen a screen like the ROM Manager screen that occurs in the bootloop right after the Google screen before. Unless maybe when making a nandroid backup through ROM Manager, not sure about this. But it shouldn't be there in a normal boot sequence as far as I understand it.
The only way I can access my Nexus7 is via USB on my PC. And I have like 5 seconds to act while this ROM Manager screen is on, that's the time frame when my PC says "Nexus7 connected" and even the Toolkit finds the device and says it's in "ADB mode", then prints the serial number, but sadly after that it waits for the device to enter adb mode forever.
EDIT: And of course I can get access in APX mode, but from what I have read there is no way to do anything because commands etc. to install a new bootloader are not known (yet?).
Thanks a lot for your help and patience, it actually helps to know there is someone who reads this :good:.
It's not the end of the world if I can't reanimate my Nexus7 but it served me so well for almost a year and I really like it .

Hello again, Jagutherrschaften...
Sorry for taking so long to get back to you, but I've been really busy with non-Android stuff all day.
Before I signed off XDA early this morning, (Fri, UK time)... and before you posted your explanation of how you got into your undesirble predicament, I was trying to think why your Nexus 7 is attempting to boot into CWM. It's something I've never seen before... it occurred to me, CWM may have been incorrectly flashed to the boot partition, instead of the recovery partition. This would go some way to explaining why your Nexus 7 is attempting to boot into CWM instead of normal Android.
So in an attempt to replicate your situation, I fastboot flashed CWM on my Nexus 7, to the boot partition with...
Code:
fastboot flash boot recovery-clockwork-touch-6.0.3.8-grouper.img
...instead of (and correctly)...
Code:
fastboot flash recovery recovery-clockwork-touch-6.0.3.8-grouper.img
Upon completion of this flash, I hit START (from the bootloader)... and as expected my Nexus 7 booted into the Google logo, and then directly into CWM.
...but it didn't bootloop as depicted in your video, it just ran CWM as normal..
I booted several times into CWM, but no bootloop. (It's kind of weird having two custom recoveries installed... there's an option in CWM to restart Recovery, which upon tapping, my N7 booted straight into TWRP !, which is my Custom Recovery of choice. And resides correctly in the recovery partition. I had to make a conscious effort to reboot as normal, in order to boot into CWM).
Anyway, more puzzled more than ever, I fastboot flashed the Jellybean 4.3 stock boot .img back to it's rightful place, rebooted the tablet, to make sure everything was working as normal, and went to bed.
Later, after you posted, I re-read it many times (and took a look at the links), and re-watched your video several more times (by the way, Nandroid backups don't backup the bootloader), and nothing occurred to me; no 'euraka' ! moment.
The bootloader is obviously still intact... if it wasn't, then your Nexus 7 wouldn't boot at all. Besides, it's there, visible, with the unlocked padlock symbol !
I'm inclined to tentatively agree with your assessment that ROM Manager screwed something up. I haven't used ROM Manager for ages, due to known issues on my Advent Vega. And on the Nexus 7, I just use fastboot. On the Vega, you use a command called flash_image to flash images, and is syntactically very similar to fastboot.
Sticking with my Vega for a moment... some users are unable to boot into CWM at all. And nobody seems to know why. But a while ago, somebody did some research into this problem, and it was speculated that on some Vegas there are BAD NAND BLOCKS (like bad sectors on a hard drive, only on a chip instead) in the MISC partition, where a binary state flag is set, telling the tablet to boot into Recovery instead of Android.
Now it's a bit a leap... and hugely speculative... but I wonder if the MISC partition on your Nexus 7 may have become corrupted... ?POSSIBLY? as a result of using ROM Manager... and that is telling the tablet to boot into Recovery instead of Android.
This is a far from satisfactory explanation, though, for several reasons...
* I'm not sure how far you can extrapolate the partition structures of one completely different tablet to another completely different tablet.
* It doesn't explain why your tablet is bootlooping and mine didn't (after replacing the stock boot.img with the CWM recovery .img in the boot partition.
* And finally... I'm still baffled why VOL DOWN+POWER ON doesn't break out of the bootloop and boot directly into the bootloader. Everything I know about the Nexus 7 tells me that this should happen... and it's always been the case, that as long as you can access the bootloader, the tablet is recoverable.
I'm afraid I have nothing else to suggest or try... other than what you've tried already.
I can only offer my apologies that I was unable to assist you... maybe somebody with more technical expertise might offer some new insight or suggestions.
Rgrds,
Ged.

Hey again GedBlake.
The last thing you have to do is apologize for helping me a lot, reading through all my text and making things clear for me. And even more you flashed stuff to your device to test if my situation can be reproduced - good that it's not . You've spent a lot of free time just to help, that's really great :good:.
With my bootloader still being intact and the device being recognized by my PC I wonder if maybe I can manage to fastboot flash a different bootloader and/or a new recovery which might maybe break the silly loop when booting. That's my only idea left but if the bootloader isn't in fastboot mode at some time during the loop this won't work too. But I'll give it a try, it's better than cutting tomatoes on my Nexus7 :laugh:.
Thank you very much for your help. If there is anything worth reporting I will of course.

Thanks for your kind words... they're appreciated.
Unfortunately, before you can fastboot flash anything, the Nexus 7 needs to be properly booted into the bootloader (the screen with the green Android lying on its back, and the word START adjacent to the POWER BUTTON)... and that requires breaking out of the bootloop first.
Indeed, if the VOL DOWN+POWER ON button combo was working as it should... breaking out of the bootloop would AUTOMATICALLY boot your Nexus 7 into the bootloader.
Finally, your bootloader doesn't need to re-flashed. One you have a stable bootloader boot, normally, (and the easiest way), would just be to flash back to factory stock.

Hey again.
Thanks for your explanation, I am not really a newbie with PCs and Tablets etc. but some things are not very interesting until you really need to know them. Like bootloader and fastboot in Android.
So the conclusion in my case is that maybe some day someone will find out how to get access to the N7 via APX - or to be precise, someone finds out or gets to know the necessary commands to flash something to the N7 over the APX-interface. Right?
Because from what I've read it doesn't really make sense to send my N7 in for repair right? Although it hasn't even had its 1st birthday yet I have no chance to get a warranty repair or exchange as it's very obvious I rooted the device and flashed stuff (the damned ROM Manager-screen clearly shows this). And ASUS charges 90 $ (or €, don't know) just for diagnosis, that's a bit much for a device that cost 199 €.
Any further advise? Could I buy a broken N7 from eBay for example and repair mine this way? I would have to change the mainboard right?
Have a nice sunday everyone .
U said you opened the battery...so wen u plugged it back in again,u shouldn't be in bootloop technically... Just a boot!...wat happens if u press the volm down and power button combo just as u insert the battery?

Hi, Jagutherrschaften...
Really sorry it had to end like this... but... perhaps it doesn't...
Nothing about your situation makes logical sense... but reading through your posts again, I find this- On the 3rd October, you posted...

Thank you for your answers. I tried every combination and kept the keys pressed for 2 mins. Nothing. The only thing I can actually do is shut the device down by pressing POWER + VOL UP for a long while.

QUOTE FOR EMPHASIS:- "...by pressing POWER + VOL UP for a long while..."
This key press combo doesn't actually shut down the device... it just pushes it into APX mode. It just looks like it's shutdown.
But that's not my point... my point is your Nexus 7 detected that key press interrupt... and acted accordingly.
It did what it was supposed to do.
Maybe you hit the buttons at JUST THE RIGHT INSTANT during the bootloop... and if it can do it for one key press combo... it can do it for another. Namely, POWER+VOL DOWN.
And for this reason... I think you need to try and try and try and try and try again... until you hit the same PRECISE TIMING SWEET SPOT... such that POWER+VOL DOWN takes you into the bootloader.
Vary the timings a bit here and there... alternate pressing the buttons, both before AND after when the Google logo appears.
By your own account... you've already done it once (you just got into the wrong mode... APX mode instead of bootloader mode).
But here's the danger... if after your Herculean efforts, you do manage, finally, to access the bootloader... you absolutely cannot afford to reboot the device normally until after you've fastboot flashed back to factory stock... otherwise the whole cycle will begin again.
So... you need, in preparation...
* A fully charged Nexus 7.
* All the drivers needed (if you don't already have them) installed on your PC.
* The Jellybean 4.3 Factory Stock image downloaded (see my Sig, second link) and unzipped and ready to go.
* A working knowledge of how to use Fastboot.
* And finally... an indomitable spirit! of perseverance... and, of course, a fair amount of free time.

I am convinced that your tablet is recoverable.
It's gotta be worth a shot... "once more unto the breach, dear friends", as old Bill Shakespeare would have it.
Anyway... the very best of luck.

@neo45215:
Technically yes, but my N7 doesn't seem to know this . Of course I've tried to get into fastboot mode right after putting back the battery as well. No chance, same bootloop.
@GedBlake:
Thanks for the encouragement, I will for sure give this a try (or several long trys to be precise). Hopefully tonight I'll have a lot of time to press keys .
And my answer to what Bill says would be: "To infinity... and beyond!"
No success so far, I tried pressing buttons for at least 1 h, nothing...
Just wanted to update the status .

Facing same problem
Hello guys. I've done pretty much the same thing and my tab is in the same boot loop that this thread is all about.
The interesting thing is that the ROM I flashed is also KaosDroid7.0.0. I'm unable to prevent any further insight. Sorry for bumping. My clockwork mod version is btw, 6.0.4.1 which proves that the problem might not be clockworkmods or even ROM manager's problem. Since I hadn't used ROM manager.
Also, Is there any way whatsoever to use this APX mode? To fix my nexus.
---------- Post added at 02:05 PM ---------- Previous post was at 01:57 PM ----------
Well, I followed OP's steps almost exactly. First I'd restored the Kitkat factory image, and then I'd proceeded to install the KD 7.0.0. And after that, I realised I'd forgotten to flash Gapps. So I rebooted and then went into CWM to reflash and after that is when my Nexus 7 became useless :crying:
---------- Post added at 02:14 PM ---------- Previous post was at 02:05 PM ----------
Jagutherrschaften, did you send in your Nexus 7 for repair?
A couple days ago, my volume buttons were not working so I thought a quick restart would fix it. But when I restarted it, it went into bootloader. Its stuck on the 'Restart bootloader' option and I can't select it with my power button nor can I select other options with my volume keys. I try and hold down the power button and it restarts into bootloader again. I booted into recovery and tried to restore it with a nandroid I made that had everything stock but that didn't work. I also did a factory reset, but every time I try to boot into system it goes to bootloader instead. The only problem I can think of was that I held my phone when my hands were wet so maybe water went inside? I'm tempted to get rice to get the water out but I want to be certain that this is the result of water damage. If it helps, I had TWRP and a very early version of Lineage OS on the device before it happened.

Hi... How did you manage to boot into recovery without the volume rocker?
Have you tried a simple:
fastboot format cache
fastboot format userdata
fastboot reboot
From bootloader?
Is your bootloader unlocked? If yes, try loading a factory image from Google if none of the above work.

I used 'fastboot boot recovery.img' to get to recovery. I tried to format the cache and userdata again, but still didn't normally boot. I also tried flashing the stock images from Google's website but still it won't boot.

I never seen this before. If you type fastboot reboot, it reboots directly into bootloader, right? I first thought avout the bootloop issue many currently report. But if you can boot a recovery.img or if your phone only reboot into bootloader, I think this scenario can be excluded.
Hmm you said you touched you phone with your hand wet?!
Could it be the moisture that oxidized the volume down contact inside of the phone? I don't have another idea. Wait for other people to chime in. Hopefully it's another (easy to solve) issue which I am unaware of.
Good luck.

No error came up when I flashed it and holding power button at bootloader restarts the phone back into bootloader. I might just stick it into some rice and use my old Nexus for now unless another solution presents itself.

Sorry for late reply, but I did manage to get if fixed. I sent it back to my phone company to get fixed since it was still under warranty (even though its rooted with unlocked bootloader). Though, they didn't really tell me what went wrong. I assumed it was a hardware problem (a piece of rice was stuck in the speaker hole and was impossible to remove but was gone when I got the phone back).
Hi, I don't have enough posts to ask this in the actual DirtySanta thread.
I meticulously followed the steps in the DirtySanta thread making sure I had all the correct software, all the pre-requisites, all files in my ADB folder (except SuperSU zip, which is on the SD card on the phone). Suffice it to say that I did all the steps exactly as written in the guide. I was prompted when to run the next batch files each time, etc. Entered the proper commands in the terminal utility, and so on. Everything as written.
After clicking on step3.bat, the phone immediately rebooted to a Fastboot screen. In the meantime, the batch files disappeared off my desktop.
So, for the past 15 minutes or so the phone has been sitting on Fastboot and vibrating away.
Here's what I see in the small Fastboot screen:
Fastboot Mode (in red)
stuff like Product_name, Variant, HW_Version, etc. up until it says LOCK_STATE.
Ok, after all of that basic stuff, it says:
[1090]
[1140] Fastboot mode started
[1670] fastboot: processing commands
[17600] usb_read() transaction failed; txn_status= -1
[17650] usb_read: DONE: ERROR len=64
[1700] fastboot: oops!
[17750] fastboot: processing commands
And that's where it sits, doing seemingly nothing and vibrating away.
Can anyone assist?

First off, a big thanks for helping me.
Update: OK, changing the USB port worked I re-ran Step3.bat. I have made it through getting to TWRP, and have done these steps:
Verizon(VS995) and ATT(H910):
4.1) Flash SuperSU.zip
4.2) Go back to Main-menu > Wipe > [Format Data] > Type ?Yes?
4.3) Go back to Wipe > Advanced > Check Dalvik, Data and Cache > Slide to wipe
4.4) Go back to Main-menu > Reboot > System
So, with that all complete, it's rebooted to a Verizon screen (horizontal progress dots) and a low buzzing.
I did try what you mentioned in the guide to get over the wait time by pulling the battery, reinserting with vol down key pressed and re-attaching the USB to flash boot2.img via fastboot, but it didn't get back to fastboot after the battery/voldown/usb. It went back to the same Verizon screen after the obligatory "Corrupt" screen came on.
Can I assume that I can wait this out for 20 minutes, or did I miss something in how to interrupt this waiting period for first setup? I do want to (and know I have to) flash boot2.img.
EDIT: wasn't holding vol key down long enough to get into fastboot. Doh. Just flashed boot2.img and rebooted.
Looks like I made it! It's at the "Prepare your Phone Screen". Fingers crossed.

Are you still stuck?
I ran into this EXACT same issue on my brand new Verizon v20 on step 3 (both 13a and 12a firmware gave me this issue) and I had to figure out my own solution, even tho I read that 'dirty santa root' thread a thousand times front to back.... (no disrepsect to the OP/Devs of that thread btw!)
Anyways, below, is the link to my solution on my brand new Verizon v20, in case you're still stuck. I've actually reflashed (via LGUP) back to stock a couple times, then re-root/unlock to test out 13a and 12a firmwares to benchmark various battery life/performance markers for a tech site I write for. Ultimately, I have to go through the exact same steps everytime for my Verizon v20.
I know I wasn't too specific in my post below... but if you have any questions, don't hesitate to ask

I read your "fix" post to see exactly where you got stuck, as I got stuck first due to the USB port not being able to work correctly and had to switch USB ports on my pc before I could re-run step3.bat.
I see now that you're talking about the long Verizon logo screen with progress dots issue after rebooting post-running step3.bat that I ran into, as well.
OK, what worked for me was much easier in the end than what you did. After step3.bat and the reboot, it would just sit there on the Verizon logo with the progress dots, as you know. There is a notation on the first page of the DirtySanta thread that in order to get around this, unplug the USB cable and remove the battery.
This is the actual note from the DirtySanta thread for Verizon users with the long Logo screen issue:
*****VERIZON USERS******
It has come to my attention that some users have encountered abnormally long first boot time(over 20 minutes before first time setup)
To resolve this issue:
Boot into bootloader by pulling the battery and reinserting it and holding VOL- and phugging in the phone. then typing:
Code:
fastboot flash boot boot2.img
fastboot reboot
**************
Click to expand...
Click to collapse
Once I removed the battery and usb cable, the phone was completely off, of course. Then, I just needed to get it back into "fastboot" on the phone, itself, in order to flash boot2.img via ADB on the PC. When the phone was on the never-ending Logo screen with progress dots, I found that ADB could see the phone ok via the adb devices command, but if I tried to flash anything at that point, it would just say something like "pending", as if it were waiting for the device to be free to flash. So, that wasn't going to work, obviously. I needed the phone to be in the flashboot screen, not the logo screen. I did a ctrl-c to cancel out of the adb flash command, and then set out to pull the battery/usb cable and then reconnect the battery, and while holding the Vol Down button reinserting the USB cable.
The first time I tried this, it booted up fine, but it went right back to the Logo screen. Doh! I figured perhaps I wasn't waiting long enough with the Volume Down button so I tried it again. What happened the first time when it rebooted to the Logo screen is I released the Volume Down button the moment the phone started to turn on (you feel the vibration). That's when it booted back to the Logo. This second time, I removed the battery again while it was on that never-ending Logo screen to power it off and disconnected the USB cable again. I put the battery back in, then with the Volume Down button pressed down, I reconnected the USB cable. The difference this time is that I did not release the Volume Down button this time UNTIL I saw it was in the Fastboot screen and not the Verizon Logo.
So, at this point the phone was on the Fastboot screen and I saw it was it was ready to go, so I initiated the ADB command to flash boot2.img. It went through its paces and once it got back to the ADB command prompt, I did an ADB Fastboot Reboot command. It rebooted, first with the obligatory corrupt warning, then the Verizon Logo and progress dots, but then after a short while I got the "Hello" screen in red and I knew it was actually going to finish. Whew! Relief! At that point I was eventually at the phone's setup screen for a new user, and I finished setting up the phone, reinstalling apps, etc.
One caveat in this: I don't know why, but even though I had gone through all the steps in "4" section of the instructions, when I checked Root, I wasn't rooted! Huh?
In other words, I had already gone through this part:
Verizon(VS995) and ATT(H910):
4.1) Flash SuperSU.zip
4.2) Go back to Main-menu > Wipe > [Format Data] > Type ?Yes?
4.3) Go back to Wipe > Advanced > Check Dalvik, Data and Cache > Slide to wipe
4.4) Go back to Main-menu > Reboot > System
Click to expand...
Click to collapse
After setting up the phone and reinstalling my apps, I opened up the SuperSU app, and it said there was no executable installed. In other words, it didn't recognize that I had flashed it in step 4.1. Perhaps flashing boot2.img overwrote that? Not sure, but at this point, I set about to figure out how to boot into TWRP Recovery on the phone (not fastboot) to flash it from there (again).
It took me a while to find the instructions on how to boot into TWRP, lol, and it's a little unnerving that before it boots to TWRPyou are warned that all your data is going to be overwritten before you can boot to it, but it did get me back into TWRP. Once in TWRP, I re-flashed Supersu-blahblah.zip and rebooted via the system reboot. (did not wipe any caches again, though).
After reboot, I checked root again, and this time after a bit SuperSu brought up the permissions screen for the Root app that I had to allow, and it brought back a successful Root message.
I then set about to do what I really wanted to do with root - bypass the Verizon entitlement check for hotspot usage, and got that working fine.
All in all, I have to say this was the diciest rooting I've ever had to go through. I guess that's because of Nougat and that there can't be (at least not yet) a "one-click" root. But man, was I worried when I was at the point where I first posted in this thread. I bought this phone as a "new-resale" (never used) phone from Swappa.com for $450, so if I bricked it, I was out of luck. But it seems to be ok now.

I saw that 'fix' and it never worked for me at the point in the rooting process I was in... sadly. You have to be able to even get to TWRP, do the SU install then format/wipe, then you can flash the boot2.img to speed up the booting process. In my case, I was never able to even get to TWRP. Trying to flash boot2.img before being able to get to TWRP, would soft brick my phone with the 'password' screen on bootup and I was never able to get around it, requiring me to LGUP back to stock and try again. Luckily I was able to still figure it out.
As you said, definitely the 'diceist' rooting process I've ever encountered... and I've been rooting phones since the original Motorola Droid 1/Milestone phone. Good times tho! Haha

Late response - sorry.
There must be something we each did differently, as we both have the same phones, same carrier, same software revision (13a). I was able to get to TWRP via the button method on the phone. Didn't use ADB for that. I was presented with an ominous white screen about all files will be wiped/deleted, but when accepting that (and hoping for the best, lol), it just went to TWRP. So, again...something or some step(s) must be done differently to get to that point on your end from what I did.
I'm guessing you're through with doing the flashing on this thing, so this is all moot now.
Hey guys i actually was having the same issues as you were now however after the SU install the wipe etc i reboot to TWRP no matter what i do even when i restart through bootloader or take the battery off it keeps booting to the same place instead to the verizon wizard help please

Sorry for the constant posts but i followed the steps on that thread, deleted the misc/fota files and it stopped it going to twrp and booted to the lg logo with the black screen, i waited there for about 2-3 hours to no avail rebooted into bootloader tried the fastboot img 2 and the same thing happened it was just stuck at the lg logo now when it boots to the fastboot screen however adb doesnt recognize the device anymore but fastboot does. Is it time to kdz and start over ?
Through my searches I couldn't quite find a problem like mine.
Here goes.
My device will not reboot into fastboot mode, using adb reboot bootloader or restarting and entering recovery mode it just restarts the system.
If I instead enter adb reboot recovery it shows a black screen with the android droid laying on it's back with a yellow triangle with an exclamation mark. text on the screen reads waiting for command but fastboot commands do nothing.
any help would be appreciated.

Hold volume down while plugging in the usb cable. With the other end of the cable plugged into your computer.

It just shows the lg screen then the charging screen.
I am having the same issue with the LG V10. There are very few mentions out on internet of the software version I have on my phone (21J). Maybe T-mobile is silently patching with and OTA to remove fastboot access?
I have the same issue. I'm on the December 2016 security patch.
Fastboot was pulled by the carriers (except TMobile, but even their fastboot is only good to unlock the bootloader).

ls996 sprint i have the same problema ....there anyway to get fastboot please
I am having the same issue on my VS995, and I was wondering if there was anyone that has found a fix/work around? This post is literally the only mention on not having fastboot, or not being able to boot into fastboot. Any help is greatly appreciated.
LG V20 Fastboot

Why on earth would they remove fastboot? Currently I am having an issue with texting, I can text everyone except my wife... I have cleared the cache, rebooted the device, removed the years of text message thread that we had on it.. Since I can text others and get no failure to send messages, (most of the time), and can make calls to my wife, (and everyone else for that matter), I believe it to be a software issue, resetting the phone to factory default I think would be a good troubleshooting step.. Also if I were to sell the phone I would love to be able to reset it to factory default, and clear all my data off the phone???

Because the carriers are wicked and want to control what you do with your phone
Sent from my LG-H910 using XDA Labs

You can do that in recovery. Hold volume down press power until the screen turns on then tap power repeatedly and itl prompt you to factory reset. It does this in stock recovery, if you're rooted itl boot into twrp (and youll have to manually enter the wipe menu and format data)
just got an "h910" from aliexpress (it says v10l), can't go into fastboot mode using the buttons or "adb reboot bootloader" ...
(but "adb reboot recovery" seems to go into recovery ...)

PS : I was fool enough to try DirtySanta for Newbies ( https://forum.xda-developers.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278 ) and it worked - at one step I had to go into fastboot with the buttons and this one time I was lucky enough and fastboot mode worked

Read the thread you just posted in. Post 8 in particular.
Dirty Santa replaced aboot (the part of the bootloader that provides (or not) fastboot) with an engineering one that does have fastboot with the ability to flash and also doesn't care if the bootloader is unlocked or not.
As much as this intrigues my curiosity, I'll take a pass for now........... I've rooted and TWRP'd phones in the past, but my past was a more simple time, with phones like the Droid, Droid-x, and those variants............ you just rooted it and it worked, simple. Nowadays, you have to jump through so many hoops, and if you miss just ONE, you probly brik'd yer phone. Nah................ will just wait some time, non rooted phones seem to do more these days
All I wanted to do was unlock bootloader and install twrp. what a bunch of bullcrap! Screw you Sprint for removing the bootloader and trying to control our phones. This phone is complete trash. I can't even install project treble for android 10.0 Q. I'm thinking about just getting an xs max and jailbreaking it. Forget android and all these fragmentation issues. At least iPhones receive updates past 2 years.
Having the same issues as everyone else. VS995. At first I thought it was only verizon... Just ordered a OnePlus 7 Pro. Hoping for something better than what the carriers can lock down.
