Hey, I have a LG K10 K425 with android 7, i want a stock LG rom without AT&T bloatware and i want to install TWRP. The problem is i cant get into Bootloader because the ADB command just restarts the phone and my phone isnt detected in Recovery mode, Please Help!
Bro did u find it?

I recently successfully unlocked bootloader on my H815 EUR version, v20a. I then proceeded to flash TWRP after booting into it from fastboot. I let the phone restart to make sure everything is ok. Then I went back into TWRP to flash SU. After that, I got a bootloop stuck at LG logo. Luckily I was able to use LG Bridge to flash back to stock and get rid of bootloop.
My question is, how come I got a bootloop? Is it worth it to try to root my phone again? I want to be able to use titanium backup to transfer stuff from my old phone. I also want to use xposed.
Has anyone successfully put a custom ROM on this device? I used to have an old Samsung S3 where I was able to put on CM and it was a piece of cake, but with this tablet I'm having issues with the bootloader being locked.
So far I've tried to install TWRP, CWM, and Philz custom recoveries. The problem seems to be with the versioning. Everything is customized for the v500. I was able to install Philz_Touch_recovery_V490.img which allowed me to boot into some sort of 'fastboot' recovery mode when before I would just get the message: "error boot certification verify" on start up. This fastboot mode isn't the Philz interface and it doesn't give me the option to back anything up or boot a ROM. It doesn't really give me any options except to restart, restart bootloader, or power off.
Were you on Lollipop or Marshmallow before you bricked it? (Which one?)
Lollipop.
The device is not bricked as I am still able to access the stock ROM. I just never was able to access my boot loader. I keep getting the error message "Error: boot certification verify" My carrier is US Cellular and they tend to lock a lot of features on their device. Is it possible they blocked boot loader access to be assholes?
BTW, my device is successfully rooted. (I checked with a root verify app.)
I'm looking into implementing the loki-master hack to unlock my boot loader and hopefully then Philz recovery will work as intended. (It is the only custom recover option that didn't give me an out-right failure message). This does seem to be an advanced developer tool requiring some code skills. Anybody have any tips for this Loki procedure?

I would doubt if you could still use the Loki method on a stock LG Lollipop ROM. For example, LG patched the Loki exploit on the VK810 LG G Pad 8.3 as of KitKat, and Lollipop on this device can't even boot the ROM using the old bootloader - it requires the Lollipop bootloader. In our case, the exploited bootloader can be temporarily reflashed to get into TWRP, but then we have to reflash the Lollipop bootloader to boot the ROM again.
sorry bring up old stuff
so i was able to root. have su i bcked up stock recovery and basicly any recover i flash i get the boot error but also gets fastboot.
ofcoarse ive tried most common commands and she wont reconize any of them.
im a long time lg user and thinking that this old of a sytem needs to be bumped like g3
att has always had a strictly locked bootloader state

can you point me to the files you used to root the device.
THank you
Lg g pad f 8.0 v495
I rooted with kingroot apk but make sure you use kingroot version no higher than 4.5 . Because you are going to want to use SuperSume to replace kingroot as superuser it runs alot smoother. And for some reason any version higher than 4.5 of kingroot the supersume always freezez u. Hope this helps. If u get time pm have a question totally unrelated to the g pad but could use some help.
Hi,
I am confused regarding my LG G4 model number.
Because Under About Phone -> Hardware Info it shows LG-H815.
But when I connect it to pc & using adb devices, adb lists it as LGLS991e484402e.
Also LS991 0423 is printed on back of the phone near camera & speaker.
But under the battery the sticker with IMEI displays LG-H815 !
What is the model number ?
I need to find it in order to update it.
Are you checking for compatibility with a rom? If so, H815 is the number you're looking for.

Don't worry about the LS991 number. H815 is the version of your phone, the G4 international.

How are you planning on updating? Flashing a rom from xda-developers? If you're not sure, I'd recommend something like imperium rom, which is based on stock and has much the same behavior but is rooted with more options. Just make sure to download the one for H815. Of course, you'll need to have an unlocked bootloader and custom recovery before you can do this. Do you have custom recovery already?

Is there any way to install custom recovery without Download mode (& of course without root !) ? Because there is one more problem ! I cant get into download mode. If I use Vol up+ & insert usb cable then I get "Secure boot error 1014" & if i use adb reboot-bootloader or reboot bootloader phone restarts normally. Also fastboot mode is not working. Fastboot devices either do nothing or waiting for device ! USB debugging & OEM unlock is on.

The only method we have for our phones at this point is to use Download mode.... have you done some research on that error? Google or the forum search tool?

Yes I have searched for that & some related errors. But almost all of them says that it is because of locked bootloader & to unlock the bootloader I need to enter fastboot mode (Not working as of now) also I have tried many drivers mentioned in the posts (LG universal, LG WHQL etc), LG Bridge, LG PC suit, LG flash tool, LG mobile support tool etc & Also tried the same things on Windows 7.
I don't really know much about fastboot problems, you'll have to look elsewhere for help. Sounds like that's your next step, though. Look for people who can help you get fastboot/download mode working.

Yes I am currently working on fastboot mode.
Hi Vishesh,
Were you able to rectify the problem and and update the phone ? I am facing the same problem with my g4 H815
Dear all,
I'm stuck and I don't know what to do.
I can't root my LG G3 D851 (T-Mobile) phone.
Recovery mode is only deleting the files (Original LG screen).
Purple, oneclickroot, kingroot they all fail cause they can't start in Recovery Mode.
I think that my Bootloader is blocking this, but LGUP doesn't recognize my Phone.
LG Flash no working DLL? I'm stuck and I'm starting to miss ODIN.
Is anyone able to help?
Cause I don't see it anymore
I have a variant of your phone, the LG G3 D858HK, I sort-of had the same issue and also found that KingRoot, Purple, etc failed, but Towelroot worked when I took the phone out Recovery Mode ..... after about the 10th attempt at trying to root using it that is...... Apparently it can take several attempts using the app before you obtain root

You can't unlock the bootloader. You have to downgrade to a lower version of lollipop, root with kingoroot, and run autorec.

Verizon doesn't support custom ROM, for your case, please flash the original firmware

Im trying to flash the original firmware into my phone but it cant boot into edl mode, which is needed for flashing stock rom.
dont plug your phone in usb while booting into edl, most of the case it wont work if you plugged in
if it dont work, force shutdown your phone and try EDL combo again
