Was fiddling around in the settings, hit check for system update, installed a >20mb update, and now my tab is stuck on the Acer boot screen with the text "booting recovery kernel image" in the upper left corner.
Anyone else had this problem?
Should I leave my tab for a few hours and hope it boots, or force a restart?
update:
held down the power button for about 5 seconds and reset with no problem.
"Update failed" window on reboot.
System update 4.010.13 (14.49) update still available when I go to system update->check now.
Currently running build 4.010.10
Does anyone have info on update 4.010.13? Hesitant to try and install it again.
You have to unroot it then install the update then root again.
Sent from my SPH-D700 using XDA App
how do you want to unroot if you can't restart?
i hope you have an external sd-card
dl one of the stock 3.1 roms and extract the update.zip (eventually you have to use the un encryption tool available in dev).
put the update.zip on your external sd-card
hit volume- and power simultaneously.
if cwm is installed you will see the cwm menu. if it is not installed it will start with the update.zip and reinstall you system, without root and cwm.
My tab is stock and unrooted but ill try the update again.
Tried to install the update a second time.
Tab restarted then displayed the same "booting recovery kernel image" screen again, but this time only for three or four seconds.
Then went to a screen with the green android guy, a bunch of turning gears, and a progress meter for a little while.
Rebooted and displayed a window "apk process installer" and some text. Looks like it worked this time.
Good to hear it worked out. Not many people have had issues with installing these OTA's while rooted and on stock. I'm sure it was just a fluke. Nevertheless...
Hello all,
Any help with this would be seriously appreciated. I rooted my Nexus 10 a while back, maybe two years ago. I'm not very proficient with this stuff. Anyhow I decided to do the OTA upgrade to 5.0...I was concerned something would go wrong unless I went to stock first, but I read that the only thing that would happen is root would be removed.
Anyhow, the tablet appears stuck while booting. I see the Google screen first with the unlocked indicator on the bottom. A few seconds later is the Android logo on its back, a red triangle over it with an exclamation point and "no command" written below". It stays that way for a minute or so, tries to reboot and goes back to the no command screen. I can't even power off, when I try to do so it just powers back on by itself and ends up at the no command screen again.
I tried booting into recovery (power, volume up, volume down). My options from here are either Start, Restart Bootloader, Recovery Mode or Power Off. Every option I choose leads to the No Command Screen (except power off, which powers off). No idea what to do from here.
Any help at all would be appreciated. As you can probably tell I don't have much experience with this and just wanted to go back to unrooted stock. If you have advice, please be clear. I can follow directions well enough, just don't have much experience here. Thanks in advance.
Same here, bootloop.
Same thing here. A seemingly short download of Lollipop (even though I have 50Mbs internet). Installation, reboot, and now it loops endlessly. I can get to the bootloader or into Download mode, but that's all. Recovery mode just reboots. I was rooted and had TWRP installed. Other than that, I was running stock 4.4.4.
I've rooted all my devices, and installed various ROM's on several devices. I have the full ADB installation. I have the Nexus Root Toolkit installed. The problem is, the device will not show up under "Devices" on the computer itself. I've installed every USB driver there is (and uninstalled each one after it does not work, so no I do not have several USB drivers installed). Of course nothing shows up using "adb devices" either. Nexus Root Toolkit also cannot find any devices. I've read everything on this subject I can find, and there are no answers out there. Anyone have ANY ideas??
Thanks
Guys, if your device is connected in fastboot (try "fastboot devices") then you can flash roms or recovery (and then flash rom) from there. There are multiple threads with the same problems out there which were fixed. E.g: http://forum.xda-developers.com/nexus-10/help/bricked-t2948546
In my example, I flashed TWRP recovery from fastboot, then installed custom ROM from recovery (official ROM failed to install for some reason). Try this, it might help.

Go to Fastboot mode (pwr+both volumes), Than select recovery after a while an android with Exclamation mark appears which is a stock recovery screen. To access the stock recovery menu press and hold power than press one of the volume keys so the menu will appear. Than do a factory reset and clear caches. You can than reboot and wait for boot animation to finish (it wont take long this time) and you will boot.
If this doesnt work you can flash a stock factory image easily from fastboot again.

I also had the same problem... I followed these instructions and now my Nexus 10 can boot normally (it took a long time to boot).
Only problem is all my data was deleted.... stup*d f*cking sh*t!!!!!!!
I was trying to upgrade from CM11 to CM12, which went smooth except for GAPPS closing constantly. I read online that this was caused by an old version of the recovery, so I tried to update TWRP to 2.8.4.0. I first tried using the TWRP app from the Play Store (after recovering my Nandroid backup), which locked the phone where it would only try booting into recovery, but couldn't get there. Holding the power button to turn it off would result in a reboot right back into recovery, which of course never went anywhere. Now I am trying to re-install TWRP using ODIN but It fails every time [Complete(Write) operation failed.] I have an early S4 from AT&T and it has never had an official update. I can't remember which firmware it is using, but it is the original so I shouldn't have any problems there. Can anybody help me get this thing up and running with either TWRP or CWM and CM12 please?!
If someone here can help you, they will. But you might have better luck asking over at http://forum.xda-developers.com/galaxy-s4-att as this is the International S4 section.
Sorry, I didn't catch that. Thank you.
Just for the record, I have been able to get the phone to boot by first booting into Download mode, then hitting the Volume Down button to cancel. This has twice booted it back into the OS. Still no recovery though.
Solved
I was able to install TWRP 2.8.4.0 from the app after getting the device to boot. It worked correctly this time and all appears to be well. Odd that ODIN didn't work though.
Just a quick suggestion...
You just need to hold down both VOLUME buttons + POWER button + HOME key to REBOOT. No need to CANCEL, etc. This is how to reboot at any stage.
Hi Guys,
Long story short, I got the root to work at first, but I was having issues with PlayStore as I couldn't install most of the apps. Then I tried wipe data and restored TWRP backup which didn't fix the problem and lost SuperSU. I tried to reflash SuperSU and failed. Lastly, I did a factory reset via the OS's settings menu and my phone would never boot into System again. I tried using LGUP tool to flash the TOT tool, but it doesn't find my device. My phone is now officially softbricked. Any help is appreciated. I will donate if that is needed
Thanks

I haven't run into this on my V20, but a couple times on my V10 when i'd softbricked my device and couldn't seem to revive it (even with ToT or KDZ files on LGUP) i was able to recover with LG bridge. Basically you go to the third tab titled "software update" but instead of selecting software update, select the "update error recovery" link at the bottom right. It takes awhile but i think it downloads and restores files (or maybe partitions) that other recovery methods don't. Give it a try and let us know if it worked.

When you plug it in does it even show up in Device Manager on your computer? If so what does it show up as?

Yeah windows sees it as a Portable Device (Attached), I can transfer files to it.
This is very similar to what happened to me, I couldn't get into TWRP though.
I could not find a resolution then and still havent, but I did return my phone for a new one.

I guess I can only wait for a custom ROM now
I'm having the same issue. I've tried every step here. I've flashed multiple ROMS, just hoping one would boot and every one keeps booting right back into TWRP after showing the "your device software cannot be checked for corruption...".
PLEASE HELP! LOL...not sure what else to do. I'm, using the latest version of TWRP and I can get into bootloader.
Tried running the "EasyRecowvery.cmd" and it loads fine. I go into twrp and do the format data and then attempt to run any of the options and I get a "This Device doesn't look like a T-Mobile V20. Proceed anyway? I stop and can't get anything. But when it initially ran it said SUCCESS when locating adb .exe and found the device as well omni_h918.
No matter what it continues to go into TWRP. ANY ANY ANY additional help would be great. I want to return this device to T-Mobile before my 14 days is up. Please help out if you can.

I had this issue on my Verizon variant the other day and I tried everything I could think of. I flashed roms, restored backups, redid the dirtysanta method several times, flashed the boot images in fastboot, and nothing worked. What finally did work (can't make any promises but this worked for me): steps below
*restore your full stock backup (if you have one)
*after the backup is restored, in TWRP, go to mount, and mount the system. Check the box and press the mount USB storage button
*power off device
*use the button combo to boot into TWRP. It's volume down + power, as soon as you see the LG logo let go of power for a breif moment and press and hold it until a white screen comes up. Choose yes for the next two options. This will bring you back into TWRP.
*now go back to mount and check system, and press the mount button, and reboot system.
This got me out of TWRP and booting normally. I haven't had an issue since.

You, sir, are a lifesaver. I jumped through all the same hoops as you and was actually starting to panic a little, as the last time I got into a similar string of unsuccessful fixes, I managed to hard brick my Note 2. This worked like a charm on my Verizon variant (the backup part was seemingly unnecessary, as my backup was toast by this point). You definitely have my thanks!

Awesome. I was getting a little worried myself when I was stuck in TWRP because I was trying everything I could think of.
I didn't think the backup part was necessary but it's one of those things where you mention everything you did just in case.

I had some trouble following this at first but it indeed worked.
My v20 was stuck in TWRP (3.0.2-1) after forgetfully hitting OK on the System Update, it was running H91810q and was previously rooted.
I first backed up my phone in TWRP to my SD card and then copied that to my laptop.
In TWRP: Mount > System, I have 3 buttons on the bottom: 'Mount USB Storage', 'Select Storage', and 'Disable MTP'. If I choose 'Mount USB Storage' it goes to the next screen and the only button is Unmount. I cannot get it to shutdown without pulling the battery.
What is missing here is to press Unmount go back to the main TWRP menu, then Reboot > Power Off.
I held Power+VolumeDown, released Power while still holding volume down and I got the white Factory data reset screen. I choose Yes on the next two options to perform the factory reset.
Then it restarted and went back into TWRP. I choose Mount, selected System, pressed Mount USB Storage, then Unmount, Reboot, System.
It booted and took a while since I also flashed the H91810t rom to do an upgrade at the same time from here:
https://forum.xda-developers.com/v20/development/rom-h91810q-stock-rom-twrp-flashable-zip-t3681312
Interesting all my apps, and settings were still on the phone.

Glad you got it working. As far as the issue with the instructions that could be down to a change in the newer versions of TWRP. I posted this 16 months ago and many new versions of TWRP have come out since. I remember trying to be extremely accurate in my instructions but it is possible I screwed up. Been too long ago and I can't remember now.
I saw it pop up on the stable channel. I waited a few days, checked here and saw nobody complaining so I went for it. Recovery saved it, so no big deal, but still killed about 20 min. 20.4 has been working fine for me.
similar result, updated and just made the phone crash at boot; restored and I guess no more updating for the meanwhile
21.3 still has the same crash.

I confirm - crashed on boot. But I am not sure that the reason is Magisk itself, may be the Magisk Manager is the reason ....
21.0 works all after do not.
Bricked my V20 VS995 this morning trying to update to 21.4. Notification had been nagging me for a week and I finally gave in, now my device has a gray screen with very small text, and at the top it says "LGE Crash Handler: Crash on the LK!". I cannot get into TWRP, and a factory reset has no effect. Still no boot into Android.
I was just talking to my girlfriend yesterday about how it was getting time to upgrade. Careful what you wish for, I guess.
that's why I finally turned off the update notification.
Have you tried booting into recovery by the holding keys method?
Assuming you have TWRP installed
hold vol down and power.
when the LG appears, release power the press and release power (one time) while still holding vol down.
you boot to the factory reset screen. select Yes twice
that will boot into twrp
Same here, updated Magisk and bricked my V20 H910.
Then I've used TWRP to try to queue install the following zip :
1 - H910_20h_Oreo_full_rooted
2 - H910_v2.2-mk2000
3 - Magisk-v19.3
4 - Hide_warning-att
Back to Oreo setup, all good even if datas are lost. Then again I've updated Magisk (was not really sure it was because of that, should have read here first!) and same problem, the unfamous "Crash on the LK!". Magisk killed my phone, again.
So I was ready for another run (but the magisk update of course). Stupid me.
I know can't even acess the recovery tool, ok for the Down/Power then Power to get the first recovery prompt and then the confirmation but no TWRP but the crashed multi-colored messy pixel screen and boot again to Crash LK screen.
I have no clue of how to get out of here, guys any help is more than welcome!
Anyone install 23 yet?
I don't see 23 on the Beta channel, nor on the stable channel.
I have 22.0 installed and running fine.
Does anyone have 22.1 installed? Is it fine?
i had an app update waiting for me 23 installed fine on note 3 and on my v20
