Just got my lp2 and it's a neat little minimal android device. The farthest I've gotten is not very far, but I can post here in case anyone's looking.
lp2, software v48 (48-release), firmware 4101.0.A.0070
fastboot:
you can enter fast boot by "hard rebooting": hold the lock and tool button simultaneously for 20-30 seconds, the phone should vibrate, then the screen will flash and it will show the "go light" screen, then turn off. Hold the power button again to turn it on, but hold the vol down button. It should stay on the "go light" screen. If it's plugged into your computer usb,
Code:
fastboot devices
should now list it. I also found it in usb info as having manufacturer "Google", while in the normal mode it has manufacturer "Android".
Code:
fastboot oem unlock
does not work.
To resume normal booting, press the lock button again.
safe mode:
if you reboot and hold down the ringer up + ringer down keys, it'll boot the phone into "safe mode". I'm not yet sure how safe mode is different from normal mode, other than there will be faint text at the bottom right of the screen saying "Safe mode". Rebooting will return it to the "normal" mode.
Has anyone else gotten any further? It's running a nonstandard base for android, so developer mode doesn't seem accessible from the menus. I'd like to at least get adb shell on this thing, but my endgoal is sideloading apps.

This is an extremely simple guide for those who are not familiar with the opportunity of going into safe mode. Safe mode disables all your third party apps and prevents them from doing anything on your device. You can install and remove new apps, but you can't open any. This is also helpful to determine whether your battery genuinely is bad, or if it is an app or two who are the culprits.
To enter safe mode:
Press and hold the power button until the 'Phone options' menu pop up.
This gives you three main options - power off, restart or turn airplane mode on.
To enter safe mode you have to press and hold 'power off' for about 3 seconds. It will then ask you whether you want to boot into safe mode or not. (Tested on D802).
On some device models, you have to tap and hold 'reboot device' in order to get that option.
It works flawlessly and in order to turn it off, you just reboot your device. During safe mode, the phone can be used as usual, with the exception of 3rd party apps.
Hope this helps!

Or, from the phone turned off, press power until the LG logo appears, release power and press the volume up button + volume down until the phone boot. You'll boot in safe mode

Thanks for guide
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks
I installed TWRP 3.0.2-1 on my Sprint Galaxy S6 Edge. I booted into recovery mode, and I'm on the normal TWRP screen with the 8 options. But it doesn't let me open any of them. After a few seconds, the lock shows up, and after a few seconds more the screen turns off. I can turn it back on with the power button but I can't use the TWRP's swipe to unlock. Holding the power button does nothing. Holding volume down, power, and home (download mode) will make the loadup screen start to show up, but then it'll stop there for a really long time, before eventually going back to TWRP recovery and repeating all over again. If I keep holding the combination, it'll just loop the loadup screen over and over again. What do I do?
EDIT: I actually can get into download mode if that helps at all, my home button is just really messed up and does not always click well.
I enabled the setting earlier where your touches are shown, and that is the only thing I can see on the screen, apart from the grey pop ups that come from the bottom when you try to use Bixby (it says that Bixby cannot be used while the power saving mode is on) or if I plug in a usb (it tells me that I can't transfer data until I enable the option to do so on the phone)
The power meter when the phone is shutdown and charging is shown too, and so is the Samsung logo on boot.
The phone still vibrates.
I don't mind factory resetting, but I cant actually transfer any of my data to my computer since it denies the permission without me enabling it on the phone.
Power button + Volume down doesn't fix it.
Power button + Volume Up + Bixby send's me to a list with a few options.
I've already tried resetting the cache, which did nothing.
Safe mode shows the words 'Safe mode' in the bottom left of the screen, but everything else stays the same. The rest of the screen is still black and the phone behaves the same way.
I have USB debugging enabled, so could I run an adb command to turn off power saving?
When someone calls me, it rings, but nothing shows up on the screen. I know that the touchscreen works but trying to press and guess the buttons didn't answer or decline. I could just be pressing on the wrong area though.
So the dog tried to eat the phone, thus the bottom part of the screen is dead so there are no software buttons to use.
Now where the problem comes in.
You go into TWRP to see if you can make a more resent backup but you can't see enough due to the strips on the screen and since the software buttons are gone you're stuck and it will lock itself and you can't even swipe to unlock. Since newer phones don't allow the battery to be pulled you're stuck until you run it down which will take days.
TWRP and any other recoveries should reboot when the power button is held down IMHO but obviously they don't. Few things are more annoying than something electrical that you can't turn off.
I found that if you hold down the volume up and volume down buttons then press and hold the power button it will force a reboot.
Forced power off is holding power down and power button: https://www.verizon.com/support/knowledge-base-215164/
This is also provided as a popup instruction when you first boot the phone after setup. So, there is a way to force it off, just not with a single button as you might prefer.
You may have found another option with the reboot process.
I can confirm this procedure worked on my Redmi Note 4 (MTK) stuck in TWRP after I executed "/sbin/recovery" from adb shell, which killed the touchscreen and USB connectivity (??). The standard way (volume down + power) did not work, but this volume up + down + power worked, strangely enough.
