Stuck in Fastboot boot loop after OTA update -- HELP! - G Pad 10.1 Q&A, Help & Troubleshooting

So I just got an LG G pad 10.1 VK700 from Verizon the other day. I rooted the device on the first day but never really added any additional apps or software.
Another member in the household was using the tablet and it asked if they wanted to accept the VZW Update for KitKat 5.0. They downloaded the update, and now the tablet is stuck in a bootloop at the Fastboot screen.
There are only 3 options I can select from this screen in the top left using the volume keys: RESTART, RESTART BOOTLOADER & POWER OFF. Any time I select either of the restart options, the screen just goes blank and hangs. I have to manually power off, and upon turning back on I am right back to this limited Fastboot menu.
Bottom left reads:
FASTBOOT MODE
PRODUCT_NAME - E9LTE_VZW
VARIANT - e9lte_vzw Toshiba 16GB
HW VERSION - rev_10
BOOTLOADER VERSION - N/A
BASEBAND VERSION - N/A
CARRIER INFO - N/A
SERIAL NUMBER - VZ7005xxxxxxx
SECURE BOOT - disabled
LOCK STATE - locked
I booted into Recovery mode, but any of the options I select from the System recovery menu send me right back to the Fastboot screen.
Is there anything to be done at this point?
UPDATE: Problem solved. Research into the other variants of the LG G Pad lead me to the the LG Mobile Support Tool, which you can find by googling B2CAppSetup.exe.
Now, if you are stuck in a Fastboot loop as I was, I ended up having to restart the device while holding down the Power + Volume UP & DOWN. This brought up a screen displaying a bar code and the device MSN and IMEI number. Using this number return to the LG Mobile Support tool and select Options>Upgrade Recovery. Even if your device is already plugged in via USB, the software will not recognize the device -- you may want to double check to make sure your device drivers were installed prior to this step. Input your IMEI number into the box and restart the device in to download mode. It took a few attempts due to the quick action of Fastboot, but I was finally able to access the menu while USB was plugged in to the device and restarting while holding the Volume + key. Now you can continue with the installation and you will be back into your tablet in no time.

I have access to the device via usb / fastboot, adb is not registering. If anyone has any suggestions on what I can try, please let me know. I do not have a backup or a version of the OEM ROM. Every effort so far just sends me right back to the Fastboot screen with 3 options. Anything I can run from command prompt using fastboot alone that would help in this situation? Any way to do a factory restore without having an actual OEM image?

Well im stuck at the verizon screen too but for a different reason

Hello I have the exact same model I got 28th my g4 and successfully rooted with kingroot and used supersume to change it to supersu. Everything was perfect and running fine and I tried an entropy engine I use on my other rooted phone and it was not help so I disabled it and rebooted like I have with my other one before and it stuck at that horrible red screen lol. I haven't done anything else major to alter anything to do with the OS like installing an OTA and I can only get to the same screens as you. My problem is I don't have a PC and haven't in a very long time and if I get to one I wouldn't know where to start out, last computer I owned has a floppy disk lol but I don't see how I would need to re flash the entire OS because of an entropy engine hickup. If you or anyone know of a way to slap this thing back to reality I would highly appreciate it. I got very familiar with the android os and how it works but never had a PC to go beyond a basic root so technically I'm still a noob in a way. I only care to expand dual window to other apps if I get it fixed cuz I'm not gonna risk screwing with it any more now than I have to, my luck is too bad lol thanks in advance

If you are stuck in this particular Fastboot loop without a computer I am afraid your options are going to be very limited. The only thing I can imagine that you would be able to try is restarting the tablet while holding down the Power + Volume Down keys to access the stock System recovery menu. You can try to use Factory data reset and Wipe cache to see if that can resolve the issue, but for me every attempt to perform actions from this menu brought me right back to the Fastboot screen. The only other way I could communicate to the device in this scenario was using command line, and even then I could only access fastboot and not abd.
I would highly advise getting at least a cheap older laptop with Windows if you plan on rooting any device, otherwise the dangers will far outweigh the benefits. I'm just hoping some development comes along for the VK700 G Pad 10.1, at least a TWRP or CWM release.

Thanks for your response, I have unfortunately tried that too and wipe cache, reset , all back to fastboot. I figured it would be impossible without a pc. Oh yea my stock recovery says modified in the top left corner, but anyway I can get access to a PC But honestly it's been awhile since I even needed to use one and don't know exactly where to start, like navigating around, and how to install what software on the pc. I can't find anyone that will walk me through it locally or online and every tutorial I find is missing some lil step I need. I know Android in detail but after basic root my experience hits a brick wall. I'm capable of more jus got to get broke in on a pc again. Now I only care to root for stuff like freezing apps, gesture control, and really want to use any app in dual window. Ain't screwing with any system tweaks again it was pointless lol I guess I need all the right files and hit up the pc...can't really do worse no??

Oh yea I almost forgot I got side tracked earlier. I know there is already a twrp, I have 2 versions (2.8...something and the next version strait off twrp site. I was the one guy it wouldn't flash through flashify for but others claimed it did. God knows really, but I'm gonna wait till I have a PC of my own before I touch my g4 but man the ability to open any app in dual window is just too damn sweet...if I could only change that one word on build prop to false without all the other hassle

I tried following your recommendation, but the LGMobile Support Tool said the device wasn't plugged in no matter which combination of buttons I pushed while running the Upgrade Recovery option, and I wasn't able to figure out how to get to download mode either.

If your problem is from an OTA failing due to taking it while modded and you can get to fastboot the following command might fix it:
Code:
fastboot erase cache
That will delete the OTA zip and break the bootloop.

[Q] Help desperately needed - Galaxy Nexus not booting after installing Jelly Belly!

I really hate to join under such a condition (it's an amazing site which I thought I would join for better reasons when time permitted), but my new Galaxy Nexus just went to hell on me after flashing the (apparently) popular Jelly Belly mod.
I started with a rooted 4.1.1 Jelly Bean OS with ClockworkMod Recovery, and now it looks like disaster after using that to flash Jelly Belly - what happens now is my phone boots up to the point where it flashes that colored Google "X", but it never proceeds beyond this point. I cannot put a different mod on my phone because there is no connection with my computer, and I can't stop my device from thrashing without a battery-pull. Is there any way save this phone and put plain Jelly Bean back on it?

When I do, I have that "Downloading..do not turn off the target!" message. Why this - I did remove the supersu file, although I think I left my clockworkmod file on the root because now you have to re-flash that every time you use it. Now I have no option other than "Start" - any chance of breaking through now?

thats not fastboot, thats odin mode. use vol up and down and power button to get to fastboot mode
the entire reason your phone is behaving the way it did is because you didnt wipe data/cache before flashing the rom.
you really need to do some reading before you start modifying your phone

Do you mean that I need to continually rock the Volume key up and down while holding the Power button? Volume Up with Power put it in boot mode, and when I tried rocking it a couple of times I got the same result. It I understand you correctly, the idea sounds tricky. Is this supposed to work on a Galaxy Nexus?
press and hold both ends of the volume button and the power button... its really not that hard.

What I really should have done was slow down, or quit while I was ahead to get some rest last night! I had researched the root process for my phone ad nauseum, which I know is why I succeeded at getting ClockworkMod safely installed. By the time that was done I was tired, but I counldn't stand the thought of living without my files loaded on my phone - I was in the bad state of needing too much to complete what I had intended to do. I see I had the wrong impression that ClockworkMod would take care of the whole process once I had that working, guess it didn't. When you've been through the process of installing a hundred versions of Windows and Linux on a PC, which never needs to be pre-wiped (the new OS does that), who would have thunk it's that much different with a phone computer?
Did you get this solved? Just reboot into recovery (hold down power, volume-up, and volume-down simultaneously to get into bootloader, choose recovery using volume buttons, select using power button), full wipe (system, data, cache), and reflash your ROM.

This is another thing I never would have guessed without being told specifically, that it's even possible to hold down both ends of a rocker switch and have it do a different function - I tried this, and now it works! I had used my PC to root my phone last night, and right now I'm at work, where there will be time to go through this in a couple of hours. I took a brief look at the tutorial recommended by Zepius, and am wondering if I am set to proceed. I plan on using my work PC, not the one at home with the drivers I used to root my phone. Nobody else uses it and I have never used it for anything phone-related. Can I presume any drivers which I'm warned should be uninstalled would be on the PC which is used, and not the phone?

Sorry, I had to work, but now there's time and I thought I would try my work PC, which is virgin (so to speak) of mobile devices and drivers. It's a Windows XP system, and right now it's not looking good because when my phone is plugged in, there isn't a "Portable Devices" or "Mobile" category under Device Manager. Do I have a better chance of this working on my home Windows 7 system?

I guess that's a never-mind, I should have had my phone on! It's in Fastboot mode now, but I still don't know if what I see in Device Manager is good for what I'm trying to do. No portable device, phone, nor galaxy nexus, but what did change is I have "Broadcom Nextreme 57xx Gigabit Controller" appearing under "Network Adapters". Is this a problem to be dealt with differently when your phone is bricked?

1) your phone is not bricked. dont call it that
2) best way to check if your drivers are installed correctly
open a command prompt in the folder where your fastboot.exe is and type: fastboot devices
if you get a device ID, your drivers are setup properly for fastboot
3) at this point, just return to stock: http://forum.xda-developers.com/showthread.php?t=1626895

I got a device ID (long string of characters) on that fastboot command, but I'm still concerned that my phone won't talk to Device Manager at all. Windows 7 doesn't pop up a connection window when it's plugged in, should that be expected?
What I mean by "not talking to Device Manager" is that the only item under Portable devices is just E:\ - no device listed here! The tutorial in your signature hinges on there being a device listed "without thde yellow exclamation point", for the installation of new drivers, therefore I don't know how to follow it from here. The adk drivers which were used to root my phone (they were good, the problem began when I tried to flash a rom and missed a step or three) are stil there, but I'll replace them if I can find a process which can talk to my phone in it's present state.
On a side note (and only because it held me up in responding tonight from my Windows system), is this site partial to Firefox? I am able for the first time to login, and I wonder if it isn't because I quit trying to through my Windows 7 system. It has only Windows IE, and Chrome (which couldn't even browse this site). I am currently on my Ubuntu system with Firefox.
good lord... you have a device ID so just use the fastboot commands... start at part D

I said much the same myself.
For the fastboot devices test, I have a string of characters, but no device name, only "fastboot" on the single output line with those characters. Is this a valid device ID?
"...just use fastboot" Ok, but how? Should (can I) even do this use fastboot to transfer files to my phone under it's somewhat anonymous status with Windows? Since last night's fiasco nothing was named under "Portable Devices", only "E:\" was displayed. I have no graphical display in the file manager, so how am I supposed to transfer the necessary files to the root of my phone? I don't even see a way of addressing it to install drivers now.
I will need drivers because I attempted to follow this tutorial (which doesn't account for what I am (not) seeing on my system. I got as far as uninstalling the good drivers which I used last night in favor of what was offered for use with the tutorial, and now Device Manager doesn't even have a Portable Devices category. The "Universal Naked Driver" was to replace my uninstalled drivers, and interestingly the contents of it's expanded folders don't even contain fastboot (the adb package which I used last night did). In light of this, how am I supposed to have even fastboot?
I hate to be a PIA about this, but I guess I'm more a n00b than was presumed in this tutorial - it's either that or my situation really is too different that I can use it as is. Could I please get a few clues in light of what the tutorial doesn't address? Do I have any means of installing anything and transferring files with my device-PC communications as they are, and if so how can I do it? I'll give it a run if I understand how.
Thanks.

I see now that Part D calls for flashing JO03C from my PC, not the device root, ok.
Also, after rebooting my laptop, the E:\ is back under Portable Devices in Device Manager. When I double-click this I get the statement
Device: Portable Devices
Manufacturer: Generic-
Location: on UMBus Enumerator
I don't think this looks better than the Microsoft default, but is it good enough for what I need to do?
I still have the driver package android-sdk-windows, which contains adb and fastboot, so perhaps I should just use this according to Part D and see what happens?

Good god, I never should have read Zepius's tutorial - I didn't need my PC at all! If I understood what bananagranola had said, I could have saved a lot of time!
Oh, no, now I can't connect with the server!
Could I have possibly lost my radio from what I did earlier? I was able to boot up, and I was upgraded to 4.2.1 when I did the data wipe. Starting over, I should have had a prompt to connect with gmail and download my contacts, but this didn't happen. My People app is unpopulated, so I chose to connect to "sign into an account". While I am sure of my login input, it didn't recognize this, and then the process ended with a "couldn't finish - couldn't open connection with the server" error. Any clue where to go from here?
Some standard apps are missing too, including the Play Store app!

[Q] Bricked - No LG Logo, No DL Mode, USB "Sounds"

Hello, first I'd like to thank you for your time reading this.
Note: I've searched the forums a lot, even for other LG Devices (G2 for ex) but I couldn't find a solution.
Trying to flash CM12 by _infected (amazing rom, working as a daily driver on my other lg pad btw) and messed up something on TWRP.
-First trying to do a Factory Reset via TWRP gave me "failed to mount /data" and "/system" I rebooted and the device went straight to TWRP Recovery, I rebooted again, this time making sure I selected "Reboot to System" and it went again to TWRP Recovery...
- I did another wipe, this time wiped everything (all checkboxes in TWRP), reboot and... no boot...
Now my LG Pad is at the following State:
- Black Screen (No LG Logo)
- Connecting USB to Windows gives the "connected sound"
- Adb doesnt find device (driver was installed and working).
- Device Manager "refreshes" on USB plug but doesnt show the device (or I can't find it?).
- Holding Power on the tablet while USB plugged to Windows gives the "disconnected sound" -> "connected sound" -> "connected sound".
- Can't boot into Download Mode.
- Can't turn off the Tablet... only Reboots holding Power key.
Please? Any help?
What can I do?
Is warranty void at this point?
Thank you very much for any help you can provide.
I have a G pad in the same situation, and I wasn't able to fix it. I managed to pick up another cheap one, but I'll follow this thread in case you get an answer.
You have to find a way to get it into download mode or you wont be able to fix it with LG Tool
What did you mess up, and how did you install twrp ? Also what twrp version abd base.

For me personally, I assumed it'd be as easy as the twrp page makes it out to be , or my nexus 4 was, so I just went for it. I ran into that secure boot error with twrp, and rebooted back into stock. There was an OTA update, so I did it (stupid I now realise) and that bricked it on reboot. It won't turn on at all. If i plug into USB on a computer it OCCASIONALLY brings something up on the screen, the LG logo I think or something, but I cannot for the life of me get it into download mode. It's at home right now, so ic anot remmeber the exact thing it shows on screen, but almost certainly not download mode, and none of the hardware buttons seem to be responsive for doing factory resets or download or anything.
I managed to send the LG G Pad to warranty and got a new one... Lucky me...
Guess that if we can't get into DL mode they can't either.
However after much investigation I've realized that the problem was a corrupted system partition...

Really Screwed Up - need some guidance

I hope I didn't end up with the proverbial brick, but I think I did. I was trying to restore my D-850 G3 to a native CM12 state to give to a family member. I did a good job with it but got stuck on not being able to change some settings. So I decided to wipe the cache and do a fresh install of CM12. I got far too aggressive and ended up wiping out everything. I have no recovery file on internal or external storage that I can access, and it appears the entire operating system is gone. I can't boot into recovery. When I try Power+volume up, nothing happens. I just get the LG startup screen and it's locked there. TWRP was on the phone but now I don't know if it is or not. If I could get to a menu and flash TWRP then CM12, I'd be OK I think (I just did that on the OnePlus 3). But I don't know how to get into the bootloader. I can probably find another way to load files onto the microSD card if that's necessary.
I tried downloading and using various LG support tools but I can't even get it recognized on USB - no adb, no fastboot, no way to get to anything.
I'd love to be able to rescue this phone from death but it's looking bleak.
Is there any hope here?
Do you remember which software you used?
I tried it on my laptop and I know it works with other phones (that aren't bricked), but all the G3 does is charge.
I installed LGMovileDriver_WHQL_ver4.04 and nothing.
Also LG PC Suite and it doesn't see anything.
I'm on Windows 10 - I do have an old PC running Win7.
If I could just get the device recognized via USB, I think it's salvagable.

I wish that worked but only resulted in the LG splash screen staying on until I removed the battery.

Question Bricked my Prixel 6 after flashing stock rom

Hi there,
I am looking for some guidance on my bricked Pixel 6 Pro.
I transfered the data from my old pixel, but then decided to do a full flash to refresh. Downloaded the stock image from google, used the fastboot-all script to flash the phone, but as soon as it was done, I never reboot. my phone is looking completely dead since.
Attempt # 1
- black screen, with no sound to any actions of response to any key combination (power or volume keys).
- tried holding the power button for 60 secs, no response
- tried holding power and volume down, no response
- tried holding power and volume up, no response
- when I plug the phone on charge, no response. neither the charging display.
Atempt # 2
- Only time the phone shows some sign of life, is when I connect the phone to my PC, it makes a sound of detecting a device, but then instantly it get a disconnect sound, (in 2-3 sec).
- I tried holding the power button, while plugged in. it makes a sound of usb detection, (but no visual response on the phone) after holder for 30 secs, it makes another sound of usb detach.
- While I am experimentating with PC connection, I also tried fastboot reboot command, it only shows waiting for a device and nothing happens, either on the console or phone.
Not sure, if I have bricked the bootloader, and if yes, what can be done? Any guidance in this regards will be highly appreciated.
Thanks
Call whoever you bought the phone from and do warranty claim.
I struggled with a soft bricked / bootlooping phone after removing Magisk. Although my phone at least booted to bootloader and a connection via fastboot was working, the factory images wouldn't flash properly. Google support couldn't help me and I thought I had to send it to repair.
In the end I could solve the issue by switching to the Android SDK 31. I know your case is different, because your phone is bricked worse than mine was, but you could give it a try.

Bootloader unlocked?

If I remeber correctly flashing factory images forces you to unlock the device. So yes, the bootloader of rao_hamza's device should be unlocked.
From memory you can revive it through QPST and orher Qualcomm utilities, however hard part is to get the files. the phone is too new and many shops dont have the unlock tools yet.
" While I am experimentating with PC connection, I also tried fastboot reboot command, it only shows waiting for a device and nothing happens, either on the console or phone. " - this is still good news, as phone is being detected by windows, try to install Qualcomm drivers and see if you can get it to boot into EDL. GOOD LUCK.
Pixel 6 uses Google's own new Tensor chip - so no Qualcomm tools
Like @Baumhouse I went through something similar. Two things for me: it took way longer to hold power and volume down than any other phone I've owned. I was seriously concerned I wasn't going to get there. Two, the factory images all made it to fastbootd and then failed all because I hadn't updated to the latest SDK.
Just throwing this out in hopes you don't have to send it back.
What @ridobe said. Make sure you're using the latest official Google Platform Tools (there's a link in my thread at the top of my signature below if you need it, or just Google for it). If I had a nickel every time someone didn't update the tools when they went to use them...

This and a bad/wrong cable seem to be the most common culprits

Any idea how long you had to hold that button combinaiton? I tried longer, maybe 60 sec, but still no response from the phone.

What is EDL? and had the Google usb drivers installed, to get the fastboot working.

Yes, I don't know who to get into a bootloader in this situation, if that were working I would have some hope.
If you can get to the bootloader you can use google's flashing website, flash.android.com. I just use that to go back to stock, even with an unlocked bootloader.

Thanks @pysklona. you are right, but the problem is I can't get into the bootloader. This is what I am seeking help for.

Sorry, misread the post.
@pysklona came here because I'm in the same boat, hard-bricked my device after running the flash-all script. Was using the most recent version of platform tools and the brand new cable that came with the phone.
Was getting the same result, attaching it to a windows pc makes the attached device chime, but disconnects after a few seconds. It came up first as "Setting up Pixel ROM Recovery". I let it sit overnight and now it doesn't auto-disconnect and I get a serial device under com3 on windows. Attaching it to macos gives me a "Pixel ROM Recovery" device. Despite "recovery" in the name, I think it's actually in EDL mode, not recovery mode. No devices come up for adb or fastboot on windows, linux or macos. Screen is completely blank no matter what.
Not being a Qualcomm chip makes this whole process from here a bit of an unknown, but will assume the process for recovery is more or less the same. Looking into QPST/MsmDownloadTool/OpenPST, although as pointed out, I'm not sure any of those tools will work since this isn't a qualcomm chip. MsmDownloadTool is for oneplus, but maybe something can be modded.

Thanks for sharing your experience. I just returned the device and got myself a new one.
anyways, i am not sure what is causing this hard brick. thats is something we all should be careful about it.
same thing here. pixel 6 from google store. magisk installed on the december update and i downgraded to the november one using the flash-all.bat script. phone reboots and am told the software is corrupt
reboot back into fastboot mode, run the script again. and get this software is corrupt message again
this time I cant' even boot into fastboot/bootloader mode. and plugging the phone into windows gives me the "pixel rom recovery" message
phone seems dead (black screen, not responding to hardware buttons)
any other solutions than to get it replaced?
Hmm, maybe plug it in to a PC via USB to supply it with power (maybe the battery is down) and just do a very long press of the power button - at least 30 seconds - until the phone starts up. If it does and isn't in fastboot you could try "Power-VolDown" to get into fastboot...
If it just doesn't react to all of this and waiting a bit (in case the battery was at 0% and needs some minimal charge) I think a replacement is the only way to go....

You could try Official Google Android Flash Tool. It's merely another method of doing what you effectively tried, but from what I've read, it's helped some folks. Sadly, others have reported that the Official Google Pixel Update and Software Repair hasn't been updated for the P6P yet.
If that doesn't help, hang in there. There are others in here who will likely have even better advice.

appreciate the links. right now, I can't even get into fastboot/bootloader mode. so neither of those tools detect the phone.
@s3axel the battery definitely isn't low. I charged it up before all this specifically so that I know it had plenty of juice (was at 93% or something).
I'm thinking maybe after letting the battery die, charging it back up will let me boot into a special boot mode
but any other ideas, please, I'm all ears

Question Phone probably hardbricked

Hi to all, yesterday I tried to root my phone following a guide here on XDA Developers (I don't remember which one). I have a Pixel 6 Pro and I tried to flash boot.img when the phone, after being restarted, starts to bootloop and then I try to turn it off. Then, the panic. The phone doesn't seem to be recognizable by ADB nor fastboot and the screen is permanently black. When I try to hold Power button and other combinations (while plugged to my PC) Windows emits some system sounds like "plugged" or "unplugged device" but I can't find my phone like recognizable.
Phone isn't hardbricked, but softbricked.
Re-flash Stock ROM.

I can't interact with phone, I just see "Pixel ROM Recovery" on devices when I connect to my PC. I don't even know if it's in recovery, if it's on or off
You might be better off if this thread was moved to the Pixel 6 Pro forum -- I can move this if you request.
But determining if you can get into Fastboot/Bootloader Mode will determine whether this is soft-bricked or not; whether this is recoverable on your end or you'll have to bring it to Google/repair shop. At this point, the only way to get into that mode is through the button combinations -- I've seen some instances where user had to hold the button combination for 1-2 minutes before it popped up; and obviously the device will need to have sufficient battery charge...

If you could move it to Pixel 6 Pro forum I'd be grateful, btw idk if I can reboot into bootloader. In fact I would like to know if I can. I tried to read this https://forum.xda-developers.com/t/...evices-with-deleted-bootloader-sboot.3573865/ but I can't understand many things. So if you know how to repair it, I would be very grateful

First and foremost is seeing if you can get to Fastboot/Bootloader Mode; When your device is off and not connected to anything (at all, no cord connecting to PC or power plug or anything), hold the Power & Volume+Down buttons simultaneously for up to 2 minutes. If you cannot power on into this mode, you will not be able to flash your device's stock firmware to re-establish any system data that may have been corrupted. It is unlikely, but you may have other options if you can boot into Recovery Mode or somehow into the OS, but if you cannot get into Fastboot Mode, it is too unlikely that you would be able to boot into these. But if you are successful into loading Bootloader/Fastboot Mode...
There's two ways i would suggest you go about it...The first and easiest is to run the official Google Android Flash Tool -- You should be able to load up the latest factory firmware version for your device (Raven), and it should be able to flash the factory image onto your phone to get it working; BE SURE to check the "keep data" (or do not wipe; I can't recall off the top of my head) and to flash to both slots (just to be safe). The second way is to follow THIS GUIDE (as directed by roirraW "edor" ehT's Pixel 6 Pro guide who holds the defacto quintessential central guide in the Pixel 7 Pro forum in which is most up to date, but not catered to "raven") -- specifically you will find what is needed in the "Update and Root Factory Image" section; play close attention to the method using the "flash-all.bat" as that is the simplest and most straightforward way to go about it.. Please read everything and place close attention on being sure to go about it without "wiping" your device (removing the "-w" in the flash-all.bat file), else if you are able to recover your system, your data will not be there when coming back to it and everything would be factory reset.
