I changed the build.prop file with the LG G6 one thinking that I would be able to install FORTNITE . But the phone failed to boot after the reboot.
The phone is stuck on the LG logo. I can access adb and shell but I cannot access SU so there's no advantage of that as I can't modify /system.
I've tried
hard reset. Does Nothing at all. Fastboot doesn't work
Installing KDZ via LG FLASH TOOL gives error "Couldn't read settings. Contact System Administrator"
LGUP gives a unknown device and When I select it, It gives an error "Please select a known deivce"
I know I have been a idiot but can anyone out there please help?

Well long story short, my G2 is semi-bricked, and i dont think i have CWM on it, but i still can get to bootloader/fastboot. But the problem is, i cant flash or do ANYTHING! when i try to use adb (example: adb devices) on a command prompt, it doesnt detect my G2 HOWEVER when i use fastboot and on the command prompt i use (fastboot devices) it detects it. and i understand that fastboot can flash boot, recovery, system etc. but when i try to flash, it gives me "FAILED <remote: signature verify fail>"
I've been working on my G2 for the past weeks already and im still stuck please help!
I've spent lots of time looking through forums trying to answer/solve my issue so I hope it's not something stupid I've missed. Sorry for the trouble if it is though.
So, my issue is that I simply cannot unlock the bootloader of my Nexus S (i9020T). The phone's connecting to my computer via Samsung Android ADB Interface as seen under the Device Manager. I see the proper device ID when I type "fastboot devices" into the adb command prompt w/ phone in fastboot mode. Then, when I type "fastboot oem unlock" the phone starts the unlock verification process -- I select yes, the phone restarts, but it goes back to the stuck Google screen. Then, if I pull the battery and go into fastboot mode directly, bootloader's still locked. I've tried this quite a few times and same result -- same result trying to unlock w/ some of the toolkits here (WugFresh's NRT, m.sabra's root tool). Haven't tried Odin but from what I've read it would also require an unlocked bootloader to do anything. I've even tried a few other things like pushing recovery and bootloader images onto the phone via adb, but these also failed due to the locked bootloader.
I also cannot enable USB debugging under phone settings either b/c I now can't get past the Google logo/fastboot mode menu. Didn't think this was required to unlock bootloader though.
Background: Phone had the latest auto updated version of Android when the phone all of a sudden turned off in the middle of the night recently. Weird b/c the battery was basically full. It now always gets stuck on the Google logo upon normal restart. It goes into fastboot mode OK if I remove the battery and press power/vol. buttons -- I then first tried the restore and recovery functions there, etc, but no effect.
Any ideas? Or is the phone just dead now?
Thanks! :fingers-crossed:
Edit:
I've now tried what's described as a possible solution here: http://forum.xda-developers.com/showthread.php?p=44753413#post44753413. It didn't work since that also needs bootloader to be unlocked.
I've also tried to solve it w/ all versions of Odin. None of them detect my phone even after installing Kies w/ drivers. I think I have the required drivers though since I can command the phone fine through adb. And Odin should need bootloader unlocked to work anyway...
Edit 2:
To add, one of the first things I tried was to do a manual factory data reset in the recovery menu (selecting 'yes' to erase all data).
And I tried adb sideload of the OTA .zip file. But installation was aborted. The following appeared immediately under the regular adb sideload instruction in the system recovery menu (under "Now send the package you want to apply to the device..."):
Finding update package...
Opening update package...
Verifying update package...
Installing update...
file_getprop: failed to stat "/system/build.prop": No such file or directory
Installation aborted.
Bump w/ more info.
Hi
This is short guide on how to install latest available Firmwares on a rooted lg stylo 2 plus ms550 [Note: this will remove root and twrp from your device and you will need to re apply the steps in my twrp thread to flash twrp and get the root back]
Steps:
1- download the latest kdz from here
https://lg-firmwares.com/lg-ms550-firmwares/
2- download lg up 1.14 from here
http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/LGUP_Store_Frame_Ver_1_14_3.msi
3- install lg up, open it and choose the upgrade option
4- choose the downloaded kdz and press start
5- wait for the phone till it reboot to the download mode, install the new firmware and after the flash is done your device will automatically reboot back to the system.
enjoy
Awesome appreciate your work!!!

I want to first thank Messie2050 for all his work on this. I know I'm making a mistake when I'm attempting to root this phone but I don't know what exactly I'm doing. I follow each step to a T. When I get to opening the command prompt and type in fastboot etc, windows says it doesn't recognize the command "fastboot" and to make sure I typed in correctly. I also tried on my netbook which is running Linux. It's slightly easier however it just waits on the device. I don't know how to extract the twrp file on a Linux machine. Can anyone help? I've tried everything to root this phone!
I am getting a msg that says invalid kdz....
Yeah, still not sure whether to use MTK or MTP.
My LG UP said LGUP can't load the model (C:/Program Files (*86)/LG Electronics/LGUP/model/com
HELP NEEDED !
I have an LG v10 H900 with F600s board. I am unable access to recovery in ANY way. and the phone is in bootloop because of editing build.prop.
Now:
1. The phone isn't rooted.
2. Fastboot mode doesn't work. Flashtool 1.8 gives previous load failed ()
3. LGUP shows Unknown | COM 10, unknown (even with UPPERCUT TOOL 1.0)
4. Flashtool 2.0 says Required info not found please contact administrator.
5. The phones stuck in LG logo although it is shown in "ADB devices " and adb commands work but useless since the phone isnt rooted.
6. "Fastboot devices" does nothing.
7. "adb reboot recovery" reboots the phone with " secure booting error 1002" & just reboots again to logo.
8. "adb reboot fastboot" simply reboots the phone.
9. upon exploring adb shell the device shows all the data is there safely.
10. Used every tool out there KDZ updater, Flash tools, LG support tool, LG bridge EVERYTHING. No luck.
Shall i say good bye to my LG v10 H900 or XDA is up for the challenge?

Hello
Well, I'm going to start from the beginning. I tried to unlock the bootloader of my lg leon lte h340ar with a guide to root and install twrp on h340n (it's supposed to be no difference in model, just change the country). Well, what I did was delete the aboot partition and "flash" through python commands an already patched aboot.bin, I did the same for the recovery. It wouldn't get into twrp, so I tried several times. I deleted it again and flashed it to aboot and twrp recovery, I also did it with the stock files to see if it works because apparently the problem was that the bootloader was not patched. Until it happened. My lg turns on, it shows the logo but a little sign appears above that says:
Error: boot certification verify
610 -
620 -
620 - secure boot error
620 - cause boot certification verify
620 -
620 -
and restarts as in an infinite loop. The only thing I can access is the data factory reset mode where it asks me if I want to return it to the factory state, but it does nothing, it restarts like this cyclically, I cannot enter the download mode either and the worst of all is that the PC does not he recognizes it. It doesn't show anything, I tried it on windows 7 and nothing. I have the drivers installed, before doing this the pc recognized it perfectly. Please, I am very worried. Any solution? This is the guide I was following to install twrp: https://forum.xda-developers.com/showpost.php?p=72501544&postcount=25
