Use newer TWRP and try new lineage-14.1-20200608-UNOFFICIAL-v500.zip.

If you're still in trouble, do recovery.log in TWRP (Advanced -> Copy Log) after a failed ROM installation

and upload the file here or a link to it.

Hi there

I am still very impressed how we can receive updates on our old G-Tab. Thank you all very much for your efforts.

There is only one thing that i feel is slower than it used to be and this is boot time in terms of booting up until beeing usable.

When I see the unlock screen it takes approximately another 60-90 seconds until i can unlock without screen stuttering or other lag problems. I can hear the notifications coming in too only about 60-90 seconds after seeing the initial screen.

I my memories it used to take a lot less time after inital boot until the tab was fully usable.

I am using kernel adiutor which kicks in (and puts it's settings) only after 30secs after booting so i wonder if i am using wrong settings for I/O or scheduler.

Do some of you have any references what makes the Tab running smooth and snappy for "normal" use (browsing, netflix, spotify)?

I do not run games or other heavy stuff on it.

Edit:

I think (but i may be wrong here) that the slowdown started after migrating to the https://www.los-legacy.de/ builds

Hi!

My actual OS on my GPAD 8.3 is LineageOS 14.1, Android 7.1.2, 11.11.2018

[G Pad 8.3 Original Android Development] JackDaniel2:
Hi,

I had the same problem - Error 7.

The solution is simple. You have to delete the whole implementation by TWRP. I cannot remember now exact command in TWRP, but it is a subcommand of DELETE and you have to confirm this execution by "yes".

You have two choices after. First - Recover your old backup or second - Instal new ZIP.

I have installed a new system without any problem. The new one looks great.

But remember, you have to have the new ZIP file on SDCARD!! Whole tablet root is deleted!!

Thanks, well-done job.

[G Pad 8.3 Original Android Development] schitthoch2:
Update Error

For me it worked. But whenever i do a direct update from Lineage-Updater or out of TWRP I do get a "Secure Boot Error" after the first reboot.

Workaround:

If you did an update please make sure you go into TWRP first and uninstall Magisk by flashing the dedicated magisk-uninstaller-2020xxyy.zip

This will replace your boot-image with an original one.

I often do a reboot recovery just to make sure, but that's probably unnecessary.

Then again from TWRP I dirty-install the Lineage-Update-zip over the installation.

I reboot directly and let it boot completely once just to make sure.

Then reboot again into TWRP and re-install Magisk with the dedicated ZIP-File and reboot again.

You may have to give several apps root permission again from within the Magisk App, but at least you will not have the ominous "Secure Boot Error".

Hope this helps for the next time.

Hello guys, I'm trying to update my V500, I'm on the last original LG Rom.

Is this link the latest official version of Lineage?The oficial website link is broken.
[G Pad 8.3 Original Android Development] BackCheck:
That link is probably the closest you will find to the last official LoS build. I'm not sure is I grabbed the last one but this was pretty close to when they quit building for the V500. That said, the build is over 2 years old. I would highly, highly recommend migrating to the unofficial builds at https://www.los-legacy.de/v500
[G Pad 8.3 Original Android Development] Thiago Moya:
Thanks!

I was reading the first post, but I don't know if all the things applies to this unofficial rom.

Does I need gapps? Does I need unlock the bootloader? Is the right TWRP the version 3.2.3-0?

Sorry to question it, probably is on some parts of the thread, but I'm a litte bit afraid to do it as the 1st post maybe is not valid anymore.

Thanks again for the help.

Is there any way to verify lineage-14.1-20201029-UNOFFICIAL-v500.zip ? I tried it with the script from the lineageos wiki but it told me that verification has failed. Because the keys don't match. I assume this is normal, because I downloaded all 3 versions of the v500 unofficial and they all failed their verification. Is there any key I can compare this with?
[G Pad 8.3 Original Android Development] Exodusnick:
the script is only if you want to switch from unofficial to official build,

Nice to get an update.
[G Pad 8.3 Original Android Development] saintalfonso:
For other noobs like me: I encountered "Error 7" issues while trying to install the latest inofficial build for v500 (14.1-20201222) with TWRP 3.3.1. My previous ROM had been a rather ancient Lineage nightly build from back when the v500 was still officially supported. I needed to wipe both system and data with TWRP to make the update work (wiping system only did not do the job). After that, installing the LineageOS image, Open GApps and the Lineage su-addon all went well.

I had another issue afterwards though, probably caused by my own stupidity. After the update I tried to recover my APKs and data using a TWRP backup from before the update (selecting data only, of course). After rebooting I repeatedly got pop-ups saying SystemUI crashed. The device was unusable. I had to factory reset the device and re-do all update steps to recover from that situation. I guess I should have created a different sort of backup - some piece of the full backup I'd restored messed up my system.

I guess I'll have to try and restore selectively somehow ... if anyone has a clue what part of the restored data might have caused the issue (and thus should be skipped next time I try restoring), or how I could figure out what the culprit was, hints would be greatly appreciated.

Hello experts!

My goal is to install the official LineageOS 14.1-20181111-nightly-signed.zip. I'm planning on flashing using "twrp-v500-3.2.3-0.img". However, this requires rooting and in the initial OP they say to Root using "Root: https://download.lineageos.org/extras [su (arm)]".

Is "su (arm)" a rooter?

Should I use towelroot instead...is there any difference?

Thank you for your response! In the offical instructions for LineageOS (which is understand is discontinued now) it states to root the device first and then install twrp. So I don't have twrp install...can't I just execute magisk.apk once its on the device to root it?
[G Pad 8.3 Original Android Development] WayneJacob:

@WayneJacob

the last official rom is not up to day with the Security String .

I would not recommend installing the official rom if security is important to you. but in the end you have to decide for yourself what rom you want to use.

Official nightlies/weeklies available

Lineage official builds (nightlies/weeklies) are here (first post updated). For a correct transition from CyanogenMod or Lineage unofficial builds to Lineage official builds, you must follow this route:

CyanogenMod 14.1 >> Lineage unofficial build >> Lineage official experimental build >> Lineage official nightly buiId.

You must boot each build at least once before flashing the next one. Once you are on latest nightly you'll get ota updates.

WARNING: If you are on CyanogenMod 14.1 and don't install Lineage unofficial build before official builds, you'll get the secure boot error on splash screen. Just as a reminder, all this only needs to be done to avoid a factory reset, if you make a clean install you can directly flash latest official build.

I installed the EXPERIMENTAL build over the current CM14.1 but when I try to boot the EXPERIMENTAL build I get "Secure booting Error! Cause : boot certification verify".

What can I do to remedy this error?

Currently stuck at the LG screen with this error.
[G Pad 8.3 Original Android Development] nsmart:
I can confirm the above. Upgrading from cm14.1 nightly did not work. I wiped system partition and installed the experimental build, opengapps and addonsu-arm-signed.zip. After reboot the secure boot error appears.

[MENTION=3084173]bland.life[/MENTION]

Hold Power + Vol Down > Wait until LG Logo pops up and release from both buttons > quickly hold Power + Vol Up + Vol Down again

It will pop up with some message about reset to factory settings, but it's all a bluff.

Hit Power 3x times to confirm and you'll get to TWRP recovery and can restore your nandroid backup.

Update:

I restored boot.img from nandroid backup (cm14.1 nightly) and secure boot error is gone.

I install experimental build only (no gapps, no root.zip) and secure boot error appears again.

Update2:

I tried to install LOS14.1 nightly, this message appears:

"Can't install this package on top of incompatible data.

Please try another package or run a factory reset

Process ended with error 7"

Solution: Seems that this error is the compatibility warning, so that you are unable to install LOS14.1 nightly on top of CM14.1 build accidentally. If you boot up experimental build once, then there is something written to the data partition, and afterwards there will be no error 7. If you have a blank data partition it works too.
[G Pad 8.3 Original Android Development] fishears:
Upgrade from unnofficial Lineage went according to plan. Thanks. I love the new boot animation.
[G Pad 8.3 Original Android Development] BackCheck:
Can you get back to recovery? If adb is not running you can always use the button sequence. If I recall, with the unit powerd off you hold the power and down volume, release the power only when the LG screen appears (still holding the down volume) hit the power and up volume keys and keep all 3 down until the factory reset screen appears. It won't reset anything, just hit the power twice to accept and you're back in TWRP. From there you can restore a backup or try reflashing.

Mine installed perfectly. The zips took a bit longer than usual to install but that was about it. I love the new boot animation. Also remember, if you want root you have to install the addon from https://download.lineageos.org/extras.

Edit: Looks like someone else beat me to the recovery boot proceedure.

[G Pad 8.3 Original Android Development] fishears:
Exactly what [MENTION=4517918]fefifofum[/MENTION] says in post #82

Not sure why people are flashing the LineageOS Experimental build over CM14.1 when the instructions we were given say that you should flash it over the unofficial Lineage build.
[G Pad 8.3 Original Android Development] nsmart:
I booted experimental build with boot.img from cm14.1 up to the pin-entry dialog for encrypted devices. I did not test beyond this point because I use device encryption and adoptable storage and at the moment I do not know what kind of impact using the old boot.img might have.
[G Pad 8.3 Original Android Development] GXGOW:
Enter recovery and try flashing this. It's a zip file which converts the 'loki' kernel to bumped and therefore gets rid of the 'boot verification failure' error. There was a thread about it somewhere, but it's probably buried deep in the forum and I was too lazy to go look for it :D
[G Pad 8.3 Original Android Development] bland.life:
I have the impression that CM had converted to Bumped since 12.1 so 14.1 should be Bumped already?

Or is there Loki in the Lineage Experimental build?
[G Pad 8.3 Original Android Development] wizzardsk:
What means bumped?
[G Pad 8.3 Original Android Development] GXGOW:
It's only the experimental build which has the issue. Nightly flashed just fine. I still use that zip to get Magisk working, otherwise you also get stuck at the 'secure boot verify' error.

---------- Post added at 05:28 PM ---------- Previous post was at 05:25 PM ----------

That's the newer exploit which was used to unlock the bootloader of our device. It's been used in all ROMs since CM12.1 as far as I know. However, if you try to flash a ROM which uses the Loki exploit (the older one), the ROM won't boot due to incompatibility between both exploits. That's why that zip was made, to convert the ROM's kernel to use the newer exploit.

Hope this clarifies it a bit.
[G Pad 8.3 Original Android Development] nsmart:
Flashing experimental build and afterwards the above mentioned zip to bump kernel worked.

After booting up the experimental build I flashed the official nightly and it booted without errors (no need to install bump kernel again).

So far everything seems fine, even with device encryption and adoptable storage enabled.
