The tool to flash recovery (after root) V50020_aboot_twrp_v2.zip worked when I plugged into usb 2.0 port; usb 3.0 port didn't work...however it did work for rooting. An easy alternate way to get recovery (after root) is using the Flashify app - use ES fileexplorer to browse to the download location, click on the twrp zip and it will ask to open with Flashify : ).

"Secure Booting Error! Cause: boot certification verify"

All day I try to install TWRP 2.7.1.0 to my tablet and all I get was this error at boot time.

I know there is a zip file in this forum with the same build of TWRP to install from within TWRP (smaler build) witch I ended doing after a day of trying.

The reason for witch I was trying to install this file (img file) instead the zip was the boot logo of TWRP, on youtube I saw another boot logo for TWRP and I was under impression was the new boot logo in img file instead the old logo from zip file with 2.7.1.0 build from here.

another reason was the dim screen at boot time in CM11. Again I see same comments on web in witch this bug is related to TWRP not to CM11, and I hoped to solve this also.

I was trying the dd method, the TWRP manager method with the same results, same error.

Lucky for us (lg owners) for the back to stock routine with lg tool, and the intial backups for may previously install (CM11 and 4.4.2 stock) on SD card from the TWRP 2.7.1.0 (zip file from here).

so anybody have a solution for theis error, I was unable to find one on this forum and the boot logo is different from this TWRP boot image, or I was wrong about this.
[G Pad 8.3 Original Android Development] jonup:
2.8 is up for our device too http://techerrata.com/browse/twrp2/awifi
[G Pad 8.3 Original Android Development] ckret:
thanks flashed via flashify

working like a charm
[G Pad 8.3 Original Android Development] json30:
same here,

flashed via flashify and now testing, the dimming on screen at boot in recovery time, seems to got away.

Edit

after I was able to restore a backup previously made with 2.7.1.0, first trouble is with CM nightly updates, it seems that update directly from Android with reboot in recovery and automated flashing is no go.

The error is like this with the latest CM update (20140911) "Error executing updater binary in zip ...." and a path to file an also this "Error installing zip file " and again a path to file.

And it seems neither from TWRP with install command doesn't work.

I think the culprit is flashify app that passes this "palman" info to the update script from cyanogenmod.

EDIT

And neither in 2.7.1.0 (made with flashify) will not work now. same error with "palman" device.

I will try to go back to 2.7.1.0 with flashify

Upon inspection it seems the scrip witch is responsable to pass all the variable at reboot to install procedure is culpable. The message witch take me to this is "This package is for "v500" devices; this is a "palman".

I do not know why it see my table to be a v510 when it is v500 model (and twrp 2.7.1.0 sees like v500).

This file was OK in TWRP 2.7.1.0 with direct update from Android

EDIT

Now got to go back (all ready in update recovery from LG desktop app
[G Pad 8.3 Original Android Development] Hibble:
I tried the official dd method from teamw.in to flash 2.8, but whenever I wanna try to access recovery I am hanging at the boot screen.

Does anyone has a hint for me?

[G Pad 8.3 Original Android Development] jonup:
I updated with Flashify and was able to boot into recovery, however I didn't do much more in there. So for those of you that are having problem flashing ROMs, I cannot guarantee it is working, but recovery did flash fine on my end and it is operational. [MENTION=3869625]json13[/MENTION], did you wipe system/data before trying to flash the ROM? It is a known issue that you need to unmount system or simply reboot recovery after full wipe. The upside, mounting and unmounting system forces to purse deleted data and in effect acts as a nice nand trim. :D

On the other hand if it was a dirty flash and you were unable to flash then it is a problem with recovery.

Also, I've used Flashify to update recovery every since the first working TWRP recovery for our tablet and haven't had any issue. Unless CM doesn't play well with Flashify, I wouldn't blame it on Flashify for bad recovery.
[G Pad 8.3 Original Android Development] legmando33:
It seems as if the recovery.img is for palman or something like that, even though file says awifi. I flashed the recovery twice. It is bootable but Anything v500 doesn't flash. Fails.

[MENTION=5029685]jonup[/MENTION] Flashing 2.8.0.0 was OK from flashify , but when I was trying to get any cm update directly from android or from install procedure from TWRP was a no go because "palman"error. So hence my idea of flashify to be the culprit. But it seems it was the build of TWRP from the download link. I will try the new link and report here.

---------- Post added at 03:00 PM ---------- Previous post was at 02:49 PM ----------

it seems there is no new build on TWRP server ( http://techerrata.com/browse/twrp2/awifi) because the date of build for 2.8.0.0 is ''2014-09-10 2:12:57 PDT'' not a a date after 11 September , so where is the new build of this
[G Pad 8.3 Original Android Development] json30:
now with the report.

link from first post (zip file of TWRP) it seems to work, update of CM from android is working . All seems to be OK, apart a slow boot at first time after update of TWRP, nothing else to mention now.

---------- Post added at 04:45 PM ---------- Previous post was at 04:12 PM ----------

another report :) from 2.8.0.0 TWRP

1. It seems if you have a usb connected (for charging purposes) and you make a reboot from android or from TWRP you get a boot loop.

2. Booting time in 2.8.0.0. for me was way more long. Exactly at error message it take like an eternity to pass to boot animation from CM 11.

3. key combination to hard reset vol down + power + vol up and again power do not get you in a reboot, it left you with same error on upper left corner and with last message from LG routine to hard reset.

so for this reasons I will get back to 2.7.1.0 for now
[G Pad 8.3 Original Android Development] BigK:
There is v2.8.0.1 out at http://techerrata.com/browse/twrp2/awifi

Is it ok if I replace recovery.img with the new img file and flash it in recovery mode?
[G Pad 8.3 Original Android Development] json30:
It is possible to work but I do not know for sure this. my bet for a good install of a new recovery file from thecherrata servers is with Flashify.

but on front page on TWRP site for build 2.8.0.0 the only new info is this :

none of the issues witch I had with this build was mentioned at solved.
[G Pad 8.3 Original Android Development] json30:
Report from 2.8.0.1

flashed img file from http://techerrata.com with flashify, reboot in recovery, wipe data,cache, dalvik, reboot system, screen was so dim I need to guess where are things on screen to configure'it.

I was able to restore a nandroid backup with a CM 11 from 12 september.

I will wait a new nightly to try update from android to see if it works now.

the good

-Boot loop with usb connected is gone.

-Slow boot time is gone

-Now it seems we are able to backup recovery partition also in a nandroid backup
[G Pad 8.3 Original Android Development] json30:
Like I was saying in previous post when update was offered I will try to update from android or from TWRP .

So today one nightly for CM 11 was on update sever, and I try to make the update, but..........no go, neither from Android or directly from TWRP.

Error message is about my tablet being a "palman" device not V500. so the update could not be applied.

Now I am back to 2.7.1.0 from first post on this threat, with this recovery update is working OK from Android

4.4.2-v500-TWRP_2.7.1.0-recovery.zip
[G Pad 8.3 Original Android Development] Drgravy:

[MENTION=4557482]Drgravy[/MENTION], thanks for suggestions, with 2.8.0.0 from OP. I flashed from TWRP with install and my experience with this version is this:

Yes it works to update CM11 from within Android via openscript

But, boot times is way much more compared with 2.7.1.0 and also reboot in recovery.

What I do not understand is how the TWRP team doesn't change the files from theirs servers with correct ones.

[G Pad 8.3 Original Android Development] woody1:
Sounds like some people are reporting issues with this version. Does it offer any major advantages over TWRP 2.7.1.0? I don't like to take chances with a recovery installation, so I'm inclined to wait until it's working without problems. What's the story from people who are using it?
[G Pad 8.3 Original Android Development] json30:
2.8.0.0 from OP, give you a slow boot in recovery. 2.8.0.1 from TWRP site give you "palaman error" on CM 11 update from Android, boot times are good. If you have a full nandroid backup you can try 2.8.0.0 or 2.8.0.1 without worry . With restore from backup you get also you actual recovery image, in your case 2.7.1.0

I download the v50020_aboot_twrp_v2.zip and the instructions say to extract and run runme.bat (but the instructions on that post say it is for v50020a)

No dice ...it wouldn't boot into recovery after I used flashify
[G Pad 8.3 Original Android Development] jonup:
Probably, I think you need custom recovery for flashify to work. Use the method in the OP. My advice was geared toward flashing twrp with your current base and change the base later. I understand the screen will be dimmer till you change the base but it won't be too dim that you wouldn't able to use recovery to flash different base. So flash recovery and then change the base. Download the base zip first.
[G Pad 8.3 Original Android Development] json30:
you need to edit runme.bat , change v50020a to v50020d . save. run and follow instructions.

and to go in recovery after succesfuly running runme.bat you can use combo from power + vol down .....….. use search for exact combo

[G Pad 8.3 Original Android Development] nigelhealy:
Help please.

I got my Gpad 8.3 (not the GPE) yesterday and I used the batch scripts out there to do a loki hack and I did install a version 2.6 of TWRP recovery which is working fine. I picked that method as it seemed to get thumbs-up works posts, albeit an old version of TWRP recovery.

I would though like to move to the most recent TWRP a 2.7 or better 2.8 because I'm sure some things I want to with custom ROMs and filesystems in the future will need newer TWRP.

I'm nervous though simply booting into recovery, my current 2.6 TWRP recovery, and flashing a newer recovery.

What is the newest recovery image I can install, should I flash it in recovery or use adb command?

adb reboot-bootloader

sudo fastboot flash recovery recovery.img

FYI my non-Android USB system is Ubuntu, so I've been copy/paste typing the commands from the Window scripts.

Dim screen

Hi all. I've scanned over many many pages in this thread and can't find an actual answer... Since flashing 2.8.00 whenever I power on or reboot the screen dims on the LG logo so dark I can barely see anything at all. This continues all the way through bootanimation until I turn my screen off and on again. I've tried flashing back to the 2.7 versions but still the same thing remains. Has anybody found a fix at all for this? Thanks in advance. :good:
[G Pad 8.3 Original Android Development] json30:

[G Pad 8.3 Original Android Development] Meakii:
Thanks I did that but it just flatly refused to boot to recovery from recovery. Instead booting into the ROM. So had to use kdz method back to 4.2.2 and start again. Now that have done that though and upgraded TWRP from 2.6 > 2.7 > 2.8 and just flashed latest Liquidsmooth nightly my dim light boot has disappeared. Took a while to get there but the end result worked out. :good:

Edit: I think because I went back to 4.2.2 and skipped stock 4.4.2 instead to LiquidSmooth 4.4.4 I managed to have sidestep the dimming issue. Hope that helps anyone with the same issue.

The description of Flashify says that it supports automatic loki support, although I have never tried using Flashify.

So, if you have to lokify the recovery image first with loki_tool, then you might as well flash the recovery.lok file with loki_tool also.

But, the recovery installation script in the twrp package provided here will automatically lokify the recovery image and install the recovery.lok file if you flash it with any custom recovery.

Help -- no adb, no recovery after flash

Hi,

So, I'm embarrassed, but I managed to clearly flash the wrong recovery from recovery -- I flashed the main linked recovery from TWRP 2.7 over the 4.4.2 base (stupidly thinking that the instructions below the link applied to the link above them). And now I seem to have lost both recovery and ADB support, and my tablet won't shutdown (it just reboots on power off) ... this seems fairly bad!

Does anyone have any suggestions? I've never encountered this situation before, and as the GPad doesn't have a fastboot mode I seem a little stuck for means of getting the right recovery back onto it ...!

Any help or advice would be greatly appreciated at this point :)
[G Pad 8.3 Original Android Development] Zeljko1234:
Flashify maybe?
[G Pad 8.3 Original Android Development] owenjm:
Sadly, no ... flashify just uses your builtin recovery to do the flashing, it seems -- not much use if your inbuilt recovery doesn't work :(

I've also tried CM's flash_image via wireless ADB (the only way I've managed to get adb working), but that gives me a very imformative "failed with error: -1" on the recovery img files I've tried so far ... :(

Any other thoughts? Really don't want to have to go through the whole LG software restore and root again (if I can even remember how to do it after all this time ...!)
