Hello, I'm on 20c with Magisk, now 20d OTA fails, is the solution the same? i.e.: flash boot_20c.img, take 20d OTA and flash boot_v20d-magisk.img?You said you were on 20b right?. Just flash original 20v and then update
Edit : 20b not 20v
Yeah thats right you need to flash it back in order to update. Also you dont have any way of flashing magisk-uninstaller and it will still not allow you to updateHello, I'm on 20c with Magisk, now 20d OTA fails, is the solution the same? i.e.: flash boot_20c.img, take 20d OTA and flash boot_v20d-magisk.img?
To flash boots, it was like this right?
adb reboot bootloader
fastboot flash boot_a Boot.img
fastboot flash boot_b Boot.img
Thanks in advance
p.s.: Or should I just flash Magisk-uninstaller.zip and reboot and then I could take the OTA and then flash boot_v20d-magisk.img???
Thank you so much!Yeah thats right you need to flash it back in order to update. Also you dont have any way of flashing magisk-uninstaller and it will still not allow you to update
I think we are describing the same procedure Step 1 -> flash boot_20c.img, Step 2 ->take 20d OTA Steps 3 & 4 -> flash boot_v20d-magisk.imgTo update I do the following:
1. Uninstall Magisk from Magisk manager restoring the original boot image.
3. Prepare or get a Magisk patched image of the newer firmware.
4. Boot this image in fastboot mode using the "fastboot boot imagefile.img" command.
5. Now you have verified that the image runs and you should have root access again. Run Magisk manager and install Magisk again(it will patch the firmware).
Using this method you allow the Magisk manager to manage the firmware patching without flashing any boot image that might not match your firmware and there's much less risk I believe to create any complications. I updated many times without an issue. Note that most likely it won't be possible to uninstall Magisk if you didn't use it's manager app to install it in the first place so you could use this method after you flash an original boot image that matches your firmware version (you could try to boot it first with the above command just to check it runs ok).
From LG site. I guess I can't root or flash?Unfortunately, your device( Guatemala, (CLARO(CENTRAL AMERICA)), LMG710EM.CAO )does not support unlocking the bootloader. Your account will be locked if you enter the wrong information more than 9 times.
Hi, how did you extract the vbmeta.img? I found the kdz extract tool, but as you said dz is an issue than.In order to get bootloader unlock you need to type
"Fastboot OEM unlock unlock.bin" you already know that. The problem is that you need an unlock.bin witch is a combination of your IMEI and other info. Obviously we can't use this method of gaining any root access to the phone.
Our second option is to open a kdz file and put a pre-patched boot image and vbmeta image. We have them but opening the kdz file is the challenge here. In the kdz there's a dll file and a dz file. The dll file is used to recognize the phone in LG up and the dz file contains everything about the system. How do I know that? Simple, there's a LG g2 firmware extraction tool that was able to read the g7 kdz. The dll and the dz files can be extracted but nothing from the dz file (but there is still a list of everything that I contains). If you want to experiment with the kdz files there are 3 versions uploaded on my Google drive that's available for everyone.
Also to point out an "adb update" command doesn't exist but you probably mean "Fastboot update". That's why I got confused. We don't use "fastboot update". We use "fastboot flash" witch flashes individual partitions because we don't have an update zip that has everything.
Also the bootloader is not in the boot image nor a partition on the phone. It's embedded in the firmware and so far I haven't heard of anyone editing it.
Just to clarify, telling people that they are stuck without root doesn't make me happy. Im just a bit tired of telling people the same thing but I have to since there's no one else to do that. I really hope for someone to make a breakthrough and get root to other models. So far there are 4 developers that are dedicated to the phone and we definitely would benefit having more.
Also "fastboot OEM unlock critical" doesn't really help is that much. It's still not sure what exactly it gives us.
Really I have no idea how to help everyone who are with locked bootloader. If you want to help us or any type of help from us you can join j0sh1x telegram group.
Use qfil to extract your own boot files and rename to .img.Hello,
the thread is a bit older, in the meantime Android 10 has been delivered fresh from LG. Does anyone know where I can get the boot image V30b (V30b-EUR-XX)?
Many greetings Torsten
