(H918) Random Rebooting after Oreo update - LG V20 Questions & Answers

Forgive me if this has been posted already before, but I could not find anyone with the same problem after extensive searching.
I bought a used V20 off of Swappa a few weeks before the Oreo update hit. It was working great until I got the notification for the update from Nougat to Oreo. I updated right away and within a few hours of light use, had several random reboots. The phone doesn't feel hot or anything, just reboots mid-use. I can be doing anything, from talking on the phone, to browsing the internet or sending a text. I'd say for every hour of screen on time, I get two reboots. I thought it might be a bad/corrupted Oreo download, so I used the LGUP software to revert it back to Nougat. While on Nougat, the reboots went away. I updated to Oreo again and the reboots came back.
Does anyone have any idea what is happening here? I'll be reverting to Nougat again tonight and keeping it that way until I can figure this out.
Also, the phone is completely stock, except the bootloader is unlocked.
EDIT: Should of also mentioned I've done a factory reset as well.

It may be necessary to hard reset the device so back up thing's and do a hard reset.....

@stinka318 Thanks for the reply. I should of mentioned that I've done a factory reset from the settings too! I edited my original post with this info.

Oh damn. All my years of using Android phones and I never knew there was a difference. Then again, I've never had problems with any of my previous phones like this so I never needed to learn. Thanks for the knowledge! I'll try it tonight and then update back to Oreo and see what happens.

No dice. Got a reboot within the first ten minutes after updating to Oreo.
I guess my next option is trying to root it and see if a custom Oreo rom does the same thing. But that laf exploit thread looks like it's gonna take a bit of reading and learning before I attempt it.

Verizon G tab and root question

Hey guys,
quick question. I just picked up a G tab and used Z4 root app. My problem is, everytime I shut off the unit and power it on, for the next use, I lose root and app downloaded apps are gone. Is this a known issue or is there something specific I need to do?
Well maybe you did temporary root ?
I know for a certain fact that after JM6 the z4root wouldnt work well, you might wanna give a go at SuperOneClick.

I try the Z4 multiple times and it was the permanent root option.
Right now it's 100% stock. Where can I get the Super One click?
I just re-booted my VZW Tab and it was rooted with Z4 and it seems to be permanent here. Not sure why yours would not be. Mine is completely stock with root.

Yeah I don't get it at all. The Z4 root app disappear from my list and the new market I installed disappears as well. I have to reinstall both after every boot. Does anyone have any ideas what to do?

I would say you should try a hard reset and re-do it.
SuperOneClicker can be found here in xda.
I can also vouch for Z4 permanent root on the Verizon Tab.
I have a real problem I think. Before I go return it, does anyone have a system dump so I can try and reflash this tab and start fresh? I did a system wipe and now Im getting FC in masses. Nothing stays installed and it keeps asking me to log in after every boot as if I just bought it.
I had a similar problem - I couldn't remove anything I had installed to one point and couldn't install anything new. I ran 'dmesg | busybox grep error' in a terminal on it and had lots of errors on the device used for the /data partition. I had to bring it back to verizon and get it replaced. New tab had been fine since then.

I ended up returning mine. Best Buy said they've never seen anything like this and there was def something wrong...lol. Really BB?
Editing,,,
Well, it worked flawlessly on my new tab so I guess it was just the defective one. Thanks guys.
OK. I rooted using Z4 I added Rom Manager and some other apps. I wanted to created a back and the tab when back to the original state, I unrooted and uninstall all the apps and rebooted the Gtab but now it bringing back to the with Rom manager FC.... any ideas?
I'm trying to do a hard reset by pressing vol up and power.... it goes into recovery and it stop about 20% I get the triangle imagen and reboots....
Can someone help me to do the right steps?
thanks
I had the issue where rebooting my tab caused everything to revert back to a previous state and giving me various force close messages. This was on a completely stock Verizon tab with no attempts at rooting. I did a full factory reset dozens of times, and every time it went back to a previous state. I posted on here about it a few weeks ago, and no one seemed familiar with the problem. I ended up returning the tab to Best Buy and exchanging it for a new one. No problems since then.

Exact same string of problems here. I too returned mine and no issues since.

[Q] N7 4.4 update issues?

Not sure if I'm the only one, and if I am that really sucks, but I got tired of waiting for the OTA and decided to install the update via the fastboot method, unlocked my bootloader installed without a problem.
However the issue now seems to stem from transferring media files to my tablet, which I never had a problem doing, a pop up window will tell me that android.media.storage has stopped, giving me an option to report and to simply tap okay.
Not sure reporting ever does anything, and if it does I've never seen it change a single thing at all, but after I tap okay or send the report, any files transferring will just exit out, then if I unplug my usb and plug it back in, it doesn't seem to recognize the tablet at all.
I've so far remedied this, not sure if it's a permanent fix or temporary, by going into settings>apps>all, then from there tapping the app, clearing data and cache, restarting my tablet with a hard reset and it seems to be working for the moment.
However transferring files since the update are sluggish at best, and taking a 356MB folder of images used to take maybe a few minutes, 5 or 7 at the most, now it's hanging there at times with the transfer time increasing.
As a matter of fact I'm transferring said 356MB folder right now and it's stuck at 10 minutes to finish and hasn't moved for about 10 minutes.
If anybody else is having these problems, can you suggest ways you've fixed it? Or do I simply need to either do a factory reset or straight up flash it again to fix the problem?
Also, I made another article detailing my problems with updating, which I've since fixed obviously, but Recovery Mode isn't anywhere to be found, I do the regular method and before it showed the android with the red triangle and below him it would say no command, now it just shows the android with the same triangle with no wording underneath at all.
I've also re-downloaded the official factory image 4.4 from google's developer site and tried to manually flash recovery onto it, and it says that it succeeded but then when it goes back to fastboot and I choose recovery it loads then shows me the android with the red triangle.
I've even tried downgrading back to 4.3 but it tells me during the rewrite of the bootloader that there's a signature mismatch.
In addition, this should be the last revision to my issue, I've even tried re-flashing 4.4 and now that's kicking back an error saying there's a signature mismatch, so I can't go into recovery, I can't downgrade, I can't flash a recovery image to my tablet, I think I screwed up in ever updating to 4.4.
Im having the same problem with Media Storage when transferring pictures via Android File Transfer on Mac, tried it on Windows also, same problem.
It happens with my Nexus 4 on KitKat also!!
I still havent found a way to fix it, did you (OP) ever find a fix?
Cheers

Nope no fix yet, I haven't tried transferring a large number of files since, oddly enough, I finally did get the OTA update and it installed 4.4 again.
It didn't take long and the file size was puny, only about 32MB, I assume it installed what was missing, but I haven't noticed anything out of the ordinary since the official updated kicked in.
Yeah I have the latest OTA also, but I am still having the same issue!!

Not really sure why it's different for you, like I said I got tired of waiting for the OTA and manually flashed the factory image, that's when the problems started, but after a few days I got a notification that the new update was ready which really confused me.
But I installed the downloaded update without a hitch, booted like normal and I just finished transferring a 100MB folder of images to my N7 without an error popping up on my tablet saying something crashed, so I can only assume for the moment until I transfer a larger folder, that the DL'd update fixed the problem.
I've also heard people flashing it again, or side loading it, or even a factory reset would fix the problem, but there weren't many replies as to this actually fixing the data transfer problem.

Take anything I say with a grain of salt as I'm not the greatest guy to ask for help, I only really ask questions here and I'm just going to suggest what to do, if you do it is up to you and I take no responsibility for your device having further issues.
1. Hard reset your device and upon it rebooting, check for the update again and try downloading it again
2. If that doesn't work then back up your data
3. After backing up your data do a factory reset on your device and once you've booted back up to Android, check for the update again and install
4. If that doesn't work, I'm not sure what else to suggest, this is what I would do to try and fix the problem, but for my situation it was unique in that I tried fixing it various ways that seemed to make it worse before it got somehow better.
I hope issuing a factory reset works for you, if not then that hard reset does when you try to redownload the update.

Thanks for your reply back. Yep i also thought of the same 4 step solution as yourself but i also heard from 2 people that had the same thing happen to them and they thought it could be a goggle server problem, So i am going to wait to see if it sorts itself out over the next few days

won't factory reset or boot into recovery

I'm having a big problem with my sm-g935v. I've had it for about 6 months now. It's on nougat 7.0 right now and I've had it rooted numerous times. It always just looses root for no apparent reason.. I used engboot root and I did t do anything out of the ordinary that would make me think I did something wrong only this last time I lost root I was flashing the Sony soundmod. It never soft bricks or anything, it just resets from setup wizard. Ever since this last time my phone has been super laggy and kinda seems like its just doing its own thing. I had enough so I was gonna reboot into recovery and it looks like its gonna do it and the blue letters come up in the top left then after 10 seconds they disappear and it just boot like normal. I tried to go into the settings and factory reset it through there and again, it looks like its gonna do it and goes throigh all the steps and resets and when it restarts nothing has changed. Im all out of ideas. Maybe something I froze when I was rooted is still frozen? Im not currently rooted even though samsung pass says i am when i click on that setting. Should my next step be flashing a new stock rom with odin or should i try something else? In all my android days ive never heard of this happening. Any help would be much appreciated, and evwruone gets a thanks that helps. Thanks

Help me PLEAAASE!

MEGA HELP PLEASE!
Guys, the next thing happened with my cell phone. He had a headache from foot bugs. I decided to install the pixel experience, installed good but wanted to return pro 8.1
I did the downgrade procedure PIE> OREO worked out, but the IMEI was reset, so my despair started. I read somewhere that updating to the PIE via ota the imei came back, I updated, however, only if the wifi was connected. I went back to pixel to see if it worked for the same thing. I followed the tutorial about the imei of typing the code in the phone. But the code did not work and soon the program did not work. I decided to redo the process back to 8.1 so now whenever I try to boot the November Patch, it loads and restarts to its initial screen to put the language, it takes a few seconds and restarts again. I've been waking up since 22hrs yesterday and I spent the whole of the night awake so far and I do not know what else to do. I've never had as much of a problem as this cell phone, so I've almost played it out: /

i have attached a screen shot of what i se in the updated screen.
any help given would be appreciated.
many thanks.
Do a factory reset. Before that, backup all your data
hey there.
sorry to ask but iff i do this will it let me do the update as there is a lot on my phone to reinstall due to the fact that i kinda use it a lot for work.
i would hate to miss some things and not have the update work.
thanks for your reply.
mark
I cannot guarantee that it will work but in theory it should. Your update is stuck because some crucial files are missing and downloaded file cannot be properly verified to start installation. Factory reset should repair that.
