I tried to root my phone for the first time.
I booted into TWRP and installed SuperSU and TWRP, then my phone rebooted.
When I try to reboot it or turn it off it does the following :
it starts booting up, then after a second it reboots again, then flashes the boot screen and repeats this a couple times until it gets stuck on the boot screen.
My phone is a LG G6 (h870) ThinQ.
Android version 8.0.0.
Everything I did prior to this :
unlocked my bootloader and that reset my phone,
after that I accidentaly wiped it again using the hard reset option (while booting holding the power button and volume down button),
then i booted into TWRP again and installed SuperSU.
This is what I followed after unlocking my bootloader : android blog.gs/how-to-root-lg-g6-and-install-twrp-recovery-on-it/
Thank you for any help.

I have been trying to update to the newest version of Lolipop for the nexus 9 and so I tried to flash the stock image. While flashing the the system.img fastboot hung and forced quit. The tablet now rebooted to the google screen and wont boot up any help is appreciated!!
I got it to boot into bootloader and just reflashed stock and this time it worked. Getting it into bootloader was tricky for some reason it wasnt letting me in for a while! I had to unplug it and hold the power button and last second push volume up,
Ok, so something seems to have gone very wrong with flashing my phone :S
I managed to get recovery working yesterday, and followed the steps in this thread, http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155 , to create a pre-rooted 5.0.2 image. I put it on the external SD card, booted into recovery and installed the flashable zip, then used flashtool to flash with the instructions (though I also cleared Appslog, Cache and Data to get a fresh install). This went fine and everything appeared to be ok. I then tried to get the Xposed Alpha installed, but after that whenever the phone was rebooting it just hung if trying to boot to Android. I tried re-flashing with Flashtool, but still got the same issue. Would boot fine the first time, but then any restart it would just hang and crash out. Tried clearing the cache from recovery, but no difference.
So today, I went into recovery, re-installed the flashable.zip, then powered off the phone and flashed using flashtool, just as I had yesterday. Now though, my phone wont boot. It shows the Sony logo, then a blank screen, then restarts. Even worse, it will no longer boot into recovery. I hold the volume down button when the LED shows, nothing. I try holding the volume down button all the way through several bootloops, nothing.
I've tried to re-flash using flashtool which goes through the process ok, I can hold the volume down button and connect the cable once its in the process of rebooting, and it goes through all the process fine. It then powers off as expected and I can just disconnect and power on the phone. But it's still stuck in the bootloop and I don't have TWRP recovery.
Is there anything I can do to get my Z2 working?
Update - Re ran flashtool, this time not excluding system, only Partition. It now gets a little further, going to "Powered by Android" and giving the purple wavy lines, but after a minute or so it just hangs and restarts again. And still no recovery sadly....
I think I've got it sorted...
Used Flashboot again to do a flash, excluding System and Partition. This time the phone does boot up normally. The downside being that my root was gone. Despite my flashing a pre-rooted image, it seemed to just put a stock image on. And my recovery is still mysteriously gone.
In the end, just to get things completely back to a stable/stock starting point for later on, I ran a repair from PC Companion. Seems I was in the none rooted position anyway so figured I'd get myself to a more certain position. At least this way I can wait for someone to come up with a root for 5.0.2 so I can root and get recovery back.
Edit:
Problem solved - phone recovered, and rooted successfully. I think the problem was that I didn't use the most recent version of SuperSU. I was using version 2.46 iirc, but I finally got the root working with version 2.76 (filename UPDATE-SuperSU-v2.76-20160630161323). The TWRP version I used is twrp-3.0.2.0-0-h960a.img. (I used this version of twrp both in the failed root attempt as well as the successful one). After I attempted root with 2.46, the phone just hung at the "your device software can't be checked for corruption". To get my phone back, I booted it and connected to USB (you might have to enter fastboot by holding the down volume button and plugging in the USB cable, keeping the down volume pressed until the phone boots, or you might just boot the phone normally and plug it into the USB cable, even though the phone will "hang" doing this, lgup can detect it and you'll be able to "refurbish" with marshmallow kdz which you should have on your computer. I updated my phone to marshmallow before attempting the root, so I had the kdz already. The one I used is v20a. Anyway, after refurbishing, the phone is recovered and usable again, you still get the "can't check for corruption" screen on boot but it only stays for 5 seconds, and then the phone starts. This is normal for an unlocked bootloader. What I did after recovering the phone was to save SuperSU 2.76 (again, filename is UPDATE-SuperSU-v2.76-20160630161323) onto my phone's SD card. Then I reflashed twrp (boot into fastboot, then from console window "fastboot flash recovery twrp-3.0.2.0-0-h960a.img". Then I had to disconnect from the USB cable, and remove the battery. Apparently some phones will perform a factory reset if you attempt a reboot via the console after installing twrp - this is why I removed the battery - then I put the battery back in and booted into recovery mode. To do this (contrary to most instructions I found online which give the wrong button presses), I held the down volume arrow, and then pressed power until the LG logo showed up. Keeping the down volume pressed, I released only the power button, then tapped the power button until I got to a recovery screen (again, keeping the down volume pressed this whole time). Select "yes" both times and you should be in TWRP. Just follow instructions from there that you can find in rooting guides. When you're ready to restart the phone, you'll get the familiar "can't check for corruption" nag screen, but this will go away after a few seconds - LG logo will briefly appear, then disappear and back to that stupid nag screen. But after a few more seconds, the phone starts up. Confirmed rooted with rootchecker!
Below is my original thread where I describe the problem
So I unlocked bootloader, installed twrp and everything fine so far. I put supersu zip file into download folder, flashed with twrp, cleared cache, and went to system reboot - now the phone just hangs at "your device software can't be checked for corruption"
I should say that instead of pushing the supersu zip to sd card, I just saved it in 'downloads' folder of the phone. I also had to do the trick where I flash twrp, and then remove battery, restart phone to recovery mode, because a reboot of the phone would not allow me to use twrp (it just did factory reset)
I can get back into twrp via recovery boot via down volume + power, and I can get into fastboot via down volume + USB cable, but I can't get anywhere else.
I installed stock recovery image from here: droidviews. com/install-stock-recovery-on-lg-v10-using-fastboot/
Went into recovery boot, the android icon shows up and starts to work, but then goes right back to "your device software can't be checked for corruption"
How can I recover this phone? It's H960A
edit:
Ok, so lgup was not recognizing it, and I couldn't install kdz to recover android. I installed lgbridge, then plugged phone in via fastboot (down arrow + usb). lgup then recognized it, and I refurbished with mm kdz. Seems ok now, but still not rooted, and I still get the "your device software can't be checked for corruption" when I boot up (afaik this is because bootloader is unlocked). Tried to root again, same issue. Except this time lgup would not recognize from fastboot, so I just booted phone normally and connected via USB. Then lgup recognized it and I was able to refurbish again
How can I root this thing? at least I have a working phone again
Hey there,
so I wanted to update LineageOS to the latest nightly (1st August) coming from an April nightly. I did it OTA, entered TWRP, installed the update and got stuck in TWRP, which is apparently a known issue with TWRP 3.0.2.0. But I didn't know that, and tried to fix it by installing a backup of CM 13 WITHOUT wiping data, because I did not want to lose my data. Stupid, I know.
I then found a fix to leave TWRP and tried booting into CM 13 but now I'm stuck in a bootloop. It shows the CM logo, then prepares apps, shows the logo, prepares apps, logo, and so on...
I can't enter Download mode or Recovery mode using the keys and adb/fastboot commands don't work while the phone is turned off or booting.
Any ideas what I can do?
Some more info:
It only bootloops when plugged into my pc. When it's unplugged (or plugged in to just power) it stays at "preparing to start". Sometimes it even leaves that screen but then the System UI keeps crashing leaving me with nothing to do but hard reboot. I still can't Recovery or Download mode tho. And whenever I plug it into my PC, it reboots
So you can't get into downloadmode with holding [Vol Up (+)] and plugin the cable into your pc at the same time?
[Edit]: Sorry, [Vol Up] is the right key.
So I got myself a cheap TF201 tablet and decided to put Android 7.1 on it using this guide. I followed the instructions completely and everything went perfectly well.
Had TWRP 3.2.3.0 installed, Android 7.1 installed and it was working great. Rebooted a few times, set up my Google account in Android, started installing a few usual apps such as Chrome, etc. when suddenly the Pad completely locked up. It then rebooted and went straight to the TWRP logo screen, sat there for 10-20 seconds then rebooted. And now that is all it does - ASUS screen comes up for a couple of seconds with "This device is unlocked" in the upper left, then tries to go into recovery but it reboots instead.
I cannot access fastboot mode at all - holding PWR + Vol DN does nothing. I can access APX mode and I can briefly use ADB while the TWRP is up.
I have backups of all blobs and I have nvflash installed - I got through the whole guide step by step without a single problem.
Any help would be hugely appreciated!
I got quite the same issue here, I also flashed 7.1.2 yesterday and installed some stuff. Then today I wanted to install Magisk to root it. After the installation (I can't remember that it was successful but I think it wasn't because there was no Magisk app to find) I wanted to boot another time to the recovery and went into a bootloop. When I'm trying to boot to TWRP it stucks at the teamwin logo. Sadly I have no cable here at the moment to maybe reflash the recovery or try some other stuff.
