So what are the bugs? I don't want to risk bricking my tablet?

I have no idea. You have to test it.

Any update on this guys?

So I would really like to test this but if it bricks my tablet without a backup it will be almost impossible to fix it? Does lg offer a restore file or KDZ I think it may be called. God's Blessing, Ron.

Need Information Before Testing

I am willing to test your TWRP, but I would like a little information first.
Can the twrp be installed with only an unlocked bootloader and NO ROOT?

The Hard Reset LG G Pad IV 8.0 FHD LTE can be found here -> https://www.hardreset.info/devices/lg/lg-g-pad-iv-80-fhd-lte/hardreset/first-method/
Will I be able to use the Hard Reset to boot into recovery?
I want to know how to boot into recovery after twrp is installed.

I installed TWRP today on an v530 with an unlocked the bootloader and NO ROOT. I could not boot into recovery. I tried the command " fastboot reboot recovery.
After the fastboot reboot recovery command I got an error screen with the android ico an the message " no command" The screen hung for about two minutes and then the v530 rebooted.
I have now lock the bootloader and did a factory reset. If you could get this twrp for v530 working it would make rooting of a v530 safer and easier.
if you do a revision of twrp I would be happy to test it.
Thank you for your hard work.

I will do some changes to the tree in my free time.

Hi. The same thing happened to my LG K10 when we ported TWRP for it. I will recollect what we had done and I will post additional instructions here for booting TWRP properly.

How did you flash TWRP?

Reboot to TWRP using:

Turn off the device.
Press and hold the Power and Volume down buttons.
When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
'Factory data reset' appears.
Use the Volume down button to highlight Yes.
Press the Power button to confirm.
Erase all user data and restore default settings' appears.
Use the Volume down button to highlight Yes.
Press the Power button to reboot to TWRP.

Flash TWRP (Second Test)

How did you flash TWRP?

Reboot to TWRP using:

Turn off the device.
Press and hold the Power and Volume down buttons.
When the LG logo appears, quickly release and then re-hold the Power button while continuing to hold the Volume down button.
'Factory data reset' appears.
Use the Volume down button to highlight Yes.
Press the Power button to confirm.
Erase all user data and restore default settings' appears.
Use the Volume down button to highlight Yes.
Press the Power button to reboot to TWRP.

This second test was on a rooted V530.

I Flashed the TWRP as follows:
adb reboot bootloader
fastboot flash recovery recovery.img
fastboot reboot
I then tried the Hard Reset Keys as shown above. You should note that no factory reset is possible if the bootloader is unlocked. Anyway I could not boot into TWRP using the hard reset keys as noted above.
I also installed the Quick Reboot App, which I am using on other rooted devices that I have, Quick Reboot would not boot into TWRP on the V530.
Lastly I tried:
adb reboot recovery
I will be happy to try again if there is a revision.

I want to add some information: The Quick Reboot (App Requires Root) works on other rooted devices that I have TWRP installed on. If I select the boot into Recovery Option from the boot menu, it boot into TWRP.
The app is on google play at -> https://play.google.com/store/apps/details?id=com.antaresone.quickreboot&hl=en_US
The use of this app is a great way of testing booting into TWRP on rooted device.
Also please note that a factory reset is not possible on a V530 with a unlocked bootloader. If you want to unroot a V530 or want to do a factory reset, just lock the bootloader and when you reboot the V530 does a factory reset.
This actually is a nice feature because it allows you to do a lot of testing without doing any harm to your V530.

I want be clear about what happens when you use the hard reset key combo. The factory reset option does appear, but there is NO TWRP option.
If you select factory reset option the tablet will rebooted, but will not do a factory reset with a locked bootloader.
Again, NO TWRP is shown as an option from the hard reset key combination screen.

No you will not have "Boot into TWRP" option. Generally, when you press those hard reset key combo you will see a screen with two buttons.

When you reach this step, just select "Yes". I know the device won't reset because of boot loader unlock but it doesn't matter.

Can you send me boot logs?

I don't know how to find boot.log
I can send you the logcat as as logcat.txt.
Can tell how to get the boot.log?

Another Test of twrp_V530

Send me the logcat.

twrpV530 Test

Tested on: LG G Pad V530 T-Mobile Tablet with UNLOCKED BOOTLOADER and NO ROOT.

Test-1) I tried to download the recovery.img to the device.
adb boot "c:\adb\recovery.img
This method works with other devices, but here got FAILED (remote: command unknown) (See Fig-1)

Test-2 I renamed recovery.img to trwp530.img and tried
adb boot "c:\adb\twrp530.img
I again got the FAILED (remote: command unknown) (see Fig-2)

Test-3 I use fastboot to flash the recovery
fastboot flash recovery twrp530.img
I got a success screen (See Fig-3)

Test-4 I used the Power and Volume Keys try and get to TWRP
There was no twrp in the menu. After using the power and volume keys the tablet
did a factory reset.

Test-5 With an UNLOCKED BOOTLOADER I flashed the recovery img then:
adb reboot recovery
This command got BOT NO command Icon screen (See Fig-4)

Test-6 I used another device I have which already has twrp installed on it.
adb reboot recovery
The above command took me into twrp

The last thing I did was to get the logcat.txt

I have uploaded a file (link below) which has the logcat.txt and the screen shots Fig-1 thur Fig-4

I hope this helps.

I think I have figured out the problem. The stock recovery is replacing twrp.
I have searched XDA and I have found that this has happen with other devices.
The BOT No command Icon is actually from the stock recovery.
Also if I use the power and volume keys I only get the stock factory reset.
Twrp does not appear anywhere in the reset menu using the power and volume keys.
The only work around that I found on XDA was to flash the device with a custom rom which allowed TWRP to replace the stock recovery.
Right now there is no custom rom available for LG G Pad V530.
I would hope that I am wrong about this, because having TWRP on a device makes everything easy and safe.
If I am wrong about this and there is a work around please let know.

Thanks Again for you hard work.
