V50020a assist?

Hope the OP is still active b/c I could use those detailed instructions...

I have the following:

LG GPad - V50020a...

Rooted w/ towelroot.apk

Recovery installed w/ Flashify

Trying to reboot into TWRP gives ==>>> Secure booting error! Cause : boot certification verify

Questions:
*If I unlock bootloader will I be able to boot into TWRP recovery?

*Is the locked bootloader actually preventing me from having a soft brick?

*Can V50020a (4.4.2) actually have a custom recovery/rom?
NB, through searching and reading, I've come across one person claiming to have TWRP working on 4.4.2 V50020a. (No guide/instructions were provided though)

Also, there doesn't look like any roms are available for my version...

*If there aren't any roms etc. for my variant, there probably isn't much point going to all this trouble.

*If it can be done, how to down grade from current scenario?

There is a fix of sorts... Will prevent you from official OTA updates :meh:

I'll see if I can find it again

....from the TWRP terminal command type (hit little centre square at bottom of terminal command screen first)

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

then hit enter

Now type

dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

then hit enter and reboot.

PS - make sure you do it exactly like above :thumbup:

Thanks a ton, this was super easy and fast. My only holdup was it took me a few minutes to realize I had to grant it access for an ADB shell in my SuperSU app.

@id10terror The link to step 1 really blew my mind because it had too many steps and files. Luckily I found this LG Flash Tool 2014 - The best way to Flash L… | LG G2 | XDA Forum
I successfully flashed the v500 with KDZ file using this.

Hello, I have an (admittedly crappy) windows xp sp3 computer. I cant get the script to work. Image #1 is when going to cmd and trying to run it from there #2 is when clicking the .bat (stays like that)

Any help please?

take this as a guess, as I haven't been using XP for long time... for some reasons between heaven and earth, your computer starts adb daemon correctly but later cannot find the application. First check the script if the path to the adb that starts the daemon is the same throughout the whole script (my guess it is). If so, copy (not move) the adb.exe to the c:/windows/system32 directory, including all .dll files. This is the directory where windows looks for the commands.

About to get crazy...

Hello everyone

I am posting here as I definitively ran out of ideas... All I am trying to do is to simply installa a custom recovery to install a new rom on my Gpad 4.4.2 build KOT491v50020d. I tried almost everything I could think of, including the step 3 at the beginning of this thread, using flashify, using some other tools that I don't even remember the name... None of them worked! I was just able to break the factory recovery and managed to restore it with the LG Mobile tool. After that, I got completely stuck. Using the method described at step 3 here seemed to work (i changed the model number as suggested to 500d), the script runs fine, it tells me it finishes, it restarts the device and then go back to the Android normal screen. Tried both with cable plugged and unplugged, no success. What else I can try? Can you help me? Thanks a lot to whoever will find me a way to get out !!!

Got my refurbished tab 2 days ago ... two OTA updates to get to 20d ... I didn't do step#1, just step# 2 then 3. After step#3, just ran flashify to reboot to TWRP recovery (I've only used flashify for that purpose) ... then update to latest TWRP 2.8 (4.4.2)... no issue whatsoever. I've tried Mahdi just for fun, but will stay with (rooted) stock for now.
(I have mahdi on my N7s and G2)

I did it!!!! Thanks for your suggestion that convinced me to try one more time!! The only thing I changed from the last time was a full wipe of the device. Done that, followed the entire procedure again and it worked like a charm!!!

Thanks again dude

Hi, I'm trying to install the TWRP recovery and have had the same problem as you, I made a cache wipe and factory reset but couldn't get the recovery to get installed. Could you please tell me how you solved in detail? thanks

Bronando · Dec 6, 2014

Is there any other way I can install TWRP without the computer or without scripts? Maybe inside the tablet? For some reason my computer works horribly with using .bat files it just doesnt recognize the directory or something.

Im itching to try out the new ROMs but unfortunately I had to factory reset.

Gmobilize · Dec 16, 2014

Hello ,as many others i want to get the aboot and flash recovery on a V20D gpad but do i really have to flash the required kdz version or can i do it in other way like modify the script or something?

Schrotty35 · Dec 24, 2014

I can not install twrp on 20b.

chris24680 · Jan 22, 2015

Does anyone have a link to the TWRP install zip, since the link in the first post just seems to go to an adware site now.

bouss · Feb 7, 2015

It seems that when in 4.4, there is no way to install a custom recovery or revert to 4.2 to do it the old way. We will wait I guess though after all this time I'm not actually optimistic.

xdax1 · Sep 9, 2015

for people on 4.4 KK 20d

this is what i found and got it working

you have to change the runme. bat from 20b to 20d like this guy below
http://xdaforums.com/lg-g-pad-83/help/current-installing-recovery-running-t2790834

then the script will run fine

and the rest, i just followed this guy and got TWRP 2.8.0.0 on my stock KK
