So to answer the first question, yes I followed the stickied guide up top, and yes, it successfully flashed the bootloader, wiped all data, and flashed stock ROM all to success. It appears my case is unique. I was told that it could be the battery connection, so I've done no fewer than half a dozen times of taking the back off, resetting the battery connection, and closing back up. It does not appear to be the battery.
I am stuck on the fastboot screen, the one where the android is lying down and blue squares project from an body. It shows me the controls I can make with the volume switches and the selection choice of 'Start'... but I cannot do anything. Before I went to flash I could move through the selection with Vol Up ONLY, but now I cannot even do that. Here's all the mode says:
Code:
FASTBOOT MODE
product name - grouper
variant - grouper
hw version - er3
bootloader version - 4.23
baseband version - n/a
serial number - ###############
signing - not defined yet
LOCK STATE - UNLOCKED
I've pretty spent the past twenty four hours on google searching through all the threads I've seen. They are either all dead, or most of them found the sticky fixed their problem. Has anyone heard of it coming to this?! All I can do is access fastbook VIA a DOS prompt and do fastboot commands, and if I disconnect the tablet from my PC, it'll remain in this mode with the screen on until the battery dies. Charging appears to charge the tablet, but again, no controls work. And yes, the buttons were set properly when I closed my tablet.
Anyone?
1) what is it exactly that your trying to do?
2) can u boot into the OS?
3) your recovery may be corrupt re-flash the recovery via fastboot

I'm just trying to boot up! I don't know what happened, but I haven't been able to use it for school all week!
I cannot boot into the OS. Any time I plug this device in it sends me to the fastboot screen with no controls.
OK I just flashed CWMR 6.0.4.3 and it did not fix the problem.
Any other ideas?
I just repeated all the steps again to see if any of them failed before, they have not worked. So recap:
Stuck in fastboot mode
Android will not boot
Loose battery connection is not the problem
I am able to access fastboot on my computer
I have followed everything from the sticky (wipe everything, flash bootloader, flash image)
I have flashed a new recovery
I am still stuck in fastboot
I cannot control options in fastboot with the volume and power buttons
I can only access fastboot by charging my tablet
The only way the tablet will power down is when it completely depletes it's battery
As far as I can tell, nothing was wrong with the tablet when it was functioning
This happened when I went to charge my tablet, presumably when the battery ran flat running android
If I charge too long the tablet gets fairly hot.
That's about all the information I can provide. Is there anything else I can try? Please, I need a tablet for school and I cannot afford a new one!
Okay, nobody say I told you so here - I was doing some reverse engineering on a ROM and wrecked it, so I went and used the LG Flash Tool to reflash the KDZ file.
This then crashed half way through, and seems to have deleted my recovery and everything. I've opened her up and disconnected the battery, then tried to turn it back on, and it can boot into recovery... sort of. It asks if I want to do a wipe, I say yes, and it suddenly boots to fastboot. Or, anything else I do, fastboot.
[EDIT] My previous problems are gone now, to be replaced by new, weird ones. Fastboot picks up my phone, and executes commands. For example, fastboot erase recovery shows on my phone as "fastboot: erase:recovery", as it should. My issue, is that it won't stop doing that. It's stuck. I have to unplug it and plug it back in to try any command, and they all freeze. fastboot reboot just shows "fastboot: reboot" on my phone, but stays on. Heeeeeelllppp!
Er, I replied instead of editing, sorry.
Hello everyone!
First of all - this is my first post here, so if I'm doing something wrong, please, correct me.
Three days ago i dropped my ALE-L21 into water closet (don't ask). I dismantled it and put into rice for 2 days. Today I decided to check if phone will start normally, but there is a following problem:
The phone is stuck into bootloop - after turning it on I see only the brand logo and after every 1 minute it vibrates for a while, the screen goes black and the brand logo appears once again. I tried to get it into recovery mode, but nothing happens. (none of button combination: holding power, power+volup or power+volup+voldown works. The phone always try to reboot)
I plugged it to PC and the only thing I can do is to get into fastboot (bootloader unlocked, phone rooted, but USB debugging is off, so adb doesn't see the device).
Any ideas of how can I fix that? Maybe just volume button is broken? Should I try to clean volume&power flex? Maybe there is an alternative solution to turn usb debugging mode on? Then I could try to recover it manually, with adb.
Flash the correct firmware in fastboot.

How can I do that?
I can run fastboot by power+vol_down, but probably USB-debugging is turned OFF. ADB doesn't see any devices plugged in.

If you pc doesn't recognize phone with adb or fastboot commands in fastboot you propably have some broken hardware.
But you can try this stuff if it recognize something.
Go to fastboot and flash TWRP with "fastboot flash recovery (recovery_filename_here).img" then try power + vol up, if it doesn't work you can try to extract UPDATE.APP app and flash system.img, boot.img, cust.img in fastboot. If TWRP works use this to re-install stock firmware https://forum.xda-developers.com/honor-4x/how-to/install-emui-4-1-4x-4c-g-play-g-play-t3515702.
Ok. Fastboot recognized my device, so I installed everything what you mentioned. Everything went 'OKAY', as it printed in cmd, but still there is no change. Whatever I am doing it freezes at brand logo and after some time reboots.
But I used branded ROM, which I downloaded from huawei website - it is the only one that not gives me "balong" error.
Any ideas before I give back my Huawei to the official service? Maybe there is some way to diagnose volume_up button?
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?
Try a different usb port. then rerun step 3.

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 ?
when reinstalling a ROM earlier today, I got an error 7 ... no problem. probably TWRP problems... so, i go to reboot phone to recovery to begin fresh, and now, TWRP boots, but the screen flashes blank every couple seconds, for a second, then the TWRP splash screen comes back up. blank screen, then TWRP splash screen again. never gets further than that. because I dont have an OS installed, i cannot access debugging for adb. because i deleted my OS, i cannot allow fastboot, to flash a new recovery and begin again. ..
I am broke, and cannot afford to pay for a new replacement thru insurance or to just go buy a junker phone and make do with that.
am i ****ed, or is this recoverable...? ive been searching the forums, but cannot seem to find the answer, and im starting to get nervous enough that its sorta beginning to compound my problems more than i can deal with.
edited to add again: .... battery removed + volume dn then insert battery will not enter fastboot. im about to paperweight this ****.
again edited - Sprint LS997 is phone model. no TOT'ing for me.
What about if you remove the battery, put it back in, hold volume down and then plug the usb cable?

tried this. still a no-go. phone screen does not power on when trying this or any other combo of steps. LAF works, which is vol+ and plug in USB cable. odd that vol- and plug in USB cable does nothing. maybe faulty vol+ button? never had a problem with that button functioning before now. i have access to: LAF (download mode), and TWRP. However, TWRP 'flashes' off n on... i see the splash screen for a second, then screen goes blank, but still powered on. then splash screen again. rinse, and repeat. no response to touch or vol/pwr buttons. tried pulling battery upon TWRP splash hoping this clears cache, but still just same story afterwards.
would having access to fastboot even matter, since I have no OS install with which to give fastboot/adb access anyway?

From fastboot you can reflash TWRP which from where you can reflash the OS which would unbrick the phone.

If you have access to download mode, can't you reflash your phone using the LGUP with the backup that did in the first place?(you did a backup of the original OS right?)

Sounds like empty or bad battery to me. When did your phone start acting up upon ya? Right after root or you had it working with root etc before u ended up into such situation.
Also, as XblackdemonX pointed out, you can still use LGUP to stock.
I'm pretty sure that happened to me. And I fixed my H990DS by flashing kdz file in download mode with LG BRIDGE.
There's a guide about how to unbrick any v20 around here.
@elijah420 What software version were you on before this started? Why does it matter? If you were on ZV7 or earlier, then you can flash a VS995 KDZ in download mode, root it, and then fix your phone. If you were on ZV8 or later, then you still might be able to salvage your phone, but you will have to run firmware from another model since you will not be able to root and flash back to Sprint firmware if you were ARB 1 or later. Better than having a totally busted phone though.
Last possibility is to use the debug firehose that I have, but that is an even bigger unknown than running firmware from another model.
