[G Pad 8.3 Original Android Development] dark0shark:
I installed a 32 GB SD-card and use it as so called Adoptable Storage in latest nightly CM14.1 Official build by [MENTION=4517918]fefifofum[/MENTION]. When booting into latest 3.0.2-1 TWRP recovery that SD-card is seen in "Select Storage" option, but I cannot access any data on it (on rare occasions I can, strange), especially not the newly downloaded CM builds. Any suggestion?
[G Pad 8.3 Original Android Development] Treanthe:
I have the same thing. When I format the SD as portable storage it works ok.
[G Pad 8.3 Original Android Development] dark0shark:
Actually I like the idea of Adopted Storage very much, as it gives the G Pad additional memory for apps and data. As I learned from https://source.android.com/devices/storage/adoptable.html this storage is encrypted with a key stored in the Android. So I wonder, if TWRP is generally able to use that key and mount the volume...
[G Pad 8.3 Original Android Development] fishears:
Same here. If I select internal it shows contents at /data/media/0 which has basically just a TWRP folder.

If I select my SD card it shows just /Android and /.LostDir

To install updates via TWRP I've been copying the zip to /data/media/0 which is on the physical internal storage and accessible in TWRP
[G Pad 8.3 Original Android Development] dark0shark:
Yes indeed, /data/media/0 does the job! Great, thanks - made my day.
[G Pad 8.3 Original Android Development] GXGOW:
I've rolled back to 3.0.2.0 for now, since that version can properly mount the adoptable storage (most of the time). The most recent one doesn't, so I'm staying away from it for now.
[G Pad 8.3 Original Android Development] fefifofum:
New build released

3.0.2-2, for v500, where adopted storage works without issues. Also, the kernel is updated to cm-14.1 and the default brightness is set to 50%.
[G Pad 8.3 Original Android Development] dark0shark:
Can confirm, adopted storage shows up in Install menu. Justed flashed cm-14.1-20161130-NIGHTLY-v500.zip successfully from that part of storage, works well. :good:
[G Pad 8.3 Original Android Development] fishears:
I get this error when I try to use cm14.1 "reboot & install update" option so the script fails but is this a TWRP issue or a cm issue? Same guy though so I guess it's not important where I post ?
[G Pad 8.3 Original Android Development] Deltadroid:
Can you tell if this error is specific to the latest official version of twrp?
[G Pad 8.3 Original Android Development] fishears:
Not with any degree of certainty, sorry ?. I know it was there the last time I tried to flash a nightly and that was either this version of twrp or the last one you sent me... HTH
[G Pad 8.3 Original Android Development] fefifofum:
Are you sure you are using latest 3.0.2-2 build? Please, provide log, it's located in /tmp/recovery.log.

FYI Cyandelta's script runs fine and installs the update then reboots as expected. CMUpdater gave the same error with 20161202 nightly as before.
[G Pad 8.3 Original Android Development] Diego1751:
what are the actual hardware differences between the v500 and v510 that prevent the v510 from flashing v500 roms?
[G Pad 8.3 Original Android Development] tmihai20:
There are differences in how internal memory is partitioned and also what resides in every partition.

I have had issues trying to run TWRP 3.0.3 on the v500 that was built on the omni android-7.1 branch. Although, I have just successfully built and tested TWRP 3.0.3 (from android-7.1) on the omni android-6.0 branch.

https://github.com/syphyr/cm_build_scripts/commit/1be4f87b52d07ece6de6de15d65cfa35e837b86a

We can use TWRP 3.0.3 if the rest is built with Omni android-6.0 sources.

sry for my bad english

i`ve installed stock kdz 20d, and after that i`ve installed a twrp recovery version 2.8.0 through runme.bat (https://xdaforums.com/showthread.php?t=2698267)

will i have a problem with installation of newest twrp with twrp manager or not? i don`t know, which bootloader i have ( kitkat or jellybean) and what is my recovery (loki or bumped)?

may have been a better way to install a new twrp in my situation?

because these apps has a lot of bugs or problems, and easy for me will install img through twrp recovery, but it needed twrp 2.8.4 or higher

There are problems with TWRP 3.0.2 making and restoring backups from Android 7.1. This issue has recently been fixed in TWRP 3.0.3.

https://gerrit.omnirom.org/#/c/21634/

I don't think this new capability is going to be backported to TWRP 3.0.2.

Flashed image in twrp and now recovery boots to fastboot screen. Think I flashed recovery partition. Is there an easy way to recover twrp back without starting fresh? I am not rooted currently but can boot lineage is.
[G Pad 8.3 Original Android Development] Deltadroid:
Make sure to verify the md5sum before flashing. That could also be the problem.
[G Pad 8.3 Original Android Development] tmihai20:
I flashed it too and I had no issues to boot into it. Recheck the img file and make sure you are using the correct version (V500, I presume).

[G Pad 8.3 Original Android Development] corvus.corax:
Please bear with me on this. I am trying to move a friends V500 from stock 4.4.2 to Lineage 14, because it's at the point where he can't run some apps he likes. I am a Samsung user, so this LG is a challenge for me. Sorry for sounding so dumb in this post, but it is different with Samsungs because they are unlocked. You just use Odin on the PC to install TWRP, then flash the zips with that. I've never done the LG way before.

In reading the opening post, I see that before I flash TWRP (I assume the latest, right?) I have to do something with the bootloader and those instructions are confusing me. Do I leave the original KitKat bootloader or do I have to put in something else?

The instructions in the OP say Warning: builds for v500 require kitkat bootloader and a few lines down it says:

Device source (v500): https://github.com/TeamWin/android_device_lge_v500

So, is that the file I have to install?

When it says to flash TWRP from recovery, is that the stock recovery, after the bootloader issue is dealt with?

Thanks for your patience.
[G Pad 8.3 Original Android Development] fishears:
Is your friend's v500 rooted? If not then that's the first thing to do. If it is then just install the Official TWRP app and then use that to install TWRP. The details for the app method are here

[MENTION=4517918]fefifofum[/MENTION] hi, I'm in the process to buy a v500 for my daughter. As I understood, I need to be rooted to install twrp and so on.

My question is: once I am done with it, may I unroot the device or I must keep it rooted? My daughter's account is linked to my Google family link and it should sniff any root on device during setup.

Thank you!
[G Pad 8.3 Original Android Development] tmihai20:
What ROM do you want to use? You do not need to keep the tablet rooted after installing that custom ROM. Root is at Android level, wiping out the tablet and installing a new ROM would not root the tablet (as long as the ROM does not come with root included already).
[G Pad 8.3 Original Android Development] Flounderist:
Silly me I forgot that I must wipe data to flash a custom ROM. :D

BTW I would go for CrDroid Pie ROM, it looks like the most updated out there. Unless some hidden development...

My main concern is rooting and downgrading the bootloader to KK. I was wondering if I can use the dd if method from adb instead of terminal.
[G Pad 8.3 Original Android Development] tmihai20:
You can only root the KitKat Rom. Wait until you get it, maybe it is already rooted. It does not matter what original ROM it has, they can all be rooted. You should some data every time you change the ROM.
[G Pad 8.3 Original Android Development] Flounderist:
It is a 5.0.2 ROM. I will try some brute force approach.
[G Pad 8.3 Original Android Development] Flounderist:
I finally rooted the device while on LP firmware using KingRoot app. Then flashed KK bootloader and twrp using adb shell and flashed last Lineage Legacy build. :good:
[G Pad 8.3 Original Android Development] TheLoonyRebel:
Stay on TWRP 3.3.1.0 folks. 3.4.0.0 doesn't seem to liking to flash certain ROMs like CRDroid for instance.
[G Pad 8.3 Original Android Development] Magendanz:
@fefifofum, can you please create a new branch for android-9.0 in your v500 device tree repo and sync any recent changes you made for TWRP 3.5.1-9.0?

I have Root'ed my KitKat v500, Flashed 2.8.7.0 .img through [ROOT] Rashr - Flash Tool https://play.google.com/store/apps/details?id=de.mkrtchyan.recoverytools&hl=tr and now running on custom LP ROM, everything great thanks for the work, just awesome :)
[G Pad 8.3 Original Android Development] D4xel:
Thank you very much! I have updated TWRP from the previus bumped 2.8.6.0 to the official 2.8.7.0 flashing this last by recovery itself.

I want ask you another questions. I had on this tablet android stock 4.4.2 (v50020D), with root and stock recovery (I bought this tablet used and I didn't ever have an LG device so I don't know this world of modding). I know that "bump!" is the system to be able to install custom recovery and custom rom/kernel also, on KK bootloader.

1. In this situation, had I KK bootloader, hadn't I? So I only can install recovery and firmware "bumped"?

2. In this situation, Could I install this recovery or first I had to install the bumped one from thread linked and then, as I have done, install this one? Or is this recovery bumped too?

3. With this recovery, can I flash every kernel and rom or only signed/bumped kernel and rom?

Sorry for my bad questions, but I'm new of LG modding in general.

Thanks a lot!
[G Pad 8.3 Original Android Development] iko11:
If you have recovery and don't have any error text on boot left up corner of tablet you are running on KK Bootloader. If you want this recovery see my old post on the thread. Root with TowelRoot Flash 2.8.7.0 TWRP img with this https://play.google.com/store/apps/details?id=de.mkrtchyan.recoverytools&hl=tr you are good to go. You can install Bumped Kernels only. But there is no Kernel around for the Stock LG Gpad. You upgrade to LP with flashable zip by flashing through TWRP, see the GPAD Android Development Section.
[G Pad 8.3 Original Android Development] Deltadroid:
If your recovery is bumped, you can still flash all ROMs (bumped and not bumped). The difference is that if you want to flash ROMs that are not bumped, you need to downgrade aboot to 4.2.2 (it has nothing to do with the recovery being bumped). Loki requires the old version of aboot from 4.2.2.

The official TWRP in this thread is already bumped.
[G Pad 8.3 Original Android Development] D4xel:
Thanks, I understand something more, I'm informing about loki, bump and so on! :good:
[G Pad 8.3 Original Android Development] odjinan:
can someone share a flashable zip? not sure twrp can flash a .img?
[G Pad 8.3 Original Android Development] Deltadroid:
Twrp can flash the image.

Screen orientation

Have successfully installed this official version - glad to see we now have an official version. A bit disappointed that I still can't seem to choose to have the LANDSCAPE option as shown on the 1st page of the TWRP explanation screen :( Is this available and I'm just being silly or is there a theme I need to download and install? Or, as I suspect, is it a generalisation and not available for the v500? Any help would be appreciated. thanx guys.
[G Pad 8.3 Original Android Development] fefifofum:
Tablet UI was historically in landscape, but that changed a long time ago. The gpad (same as many other tablets) has the screen in vertical position, that's why you don't get a landscape UI. There isn't an option to change the screen orientation in recovery, so don't get disappointed, that's just the way it is...
[G Pad 8.3 Original Android Development] coubi64:
I flashed twrp 2.8.7.0 with rashr app (I have Slimkat, android 4.4.4 custom rom) but when booting to recovery i have this message "Fastboot mode started udc_start()" . How do i solve this problem?
[G Pad 8.3 Original Android Development] fefifofum:
I think that happens after a failed flash of recovery. Download TWRP again and flash it to see if that solves the issue.
[G Pad 8.3 Original Android Development] Deltadroid:
The gpad is meant to be held in portrait mode from the position of it's front facing camera.
[G Pad 8.3 Original Android Development] robroy49:
Screen orientation

Thanks fefifofum. Have to say that I suspected that. Only a small thing - it's just that I have my tablet in a case with keyboard so tend to use it in landscape mode. No big deal really, just thought that if it's possible . . . :)

Is something wrong with the download links? Keep getting a hml file of 5kb...with both links. :confused:
[G Pad 8.3 Original Android Development] fefifofum:
It's not a direct download link (that's why TWRP manager app doesn't have the latest updates). You have to click here, then click on "twrp-2.8.7.0-v500.img" (that's an html file, not the recovery img), and once it opens you click on "Download twrp-2.8.7.0-v500.img". And that's when you get to download the recovery img file.

TWRP 2.8.7.1 update for v500

There is a new build of TWRP for v500 with the following changes:

- F2FS support.

- Default I/O scheduler set to NOOP.

- Kernel updates from VK81035A.
[G Pad 8.3 Original Android Development] Deltadroid:
When I flashed the new twrp image and rebooted the recovery, the recovery started up with a screen that was asking for permission to modify the system. I've never seen that before.
[G Pad 8.3 Original Android Development] ol31:
Same for me
[G Pad 8.3 Original Android Development] fefifofum:
That is the system read only option, explained in the changelog of 2.8.7.0:

I'm not sure why we didn't get that prompt before with the 2.8.7.0 build.
[G Pad 8.3 Original Android Development] Deltadroid:
I've also noticed that the screen timeout is set to one minute by default. If I perform an automatic update, twrp times out before the update finishes and the update process stops until I unlock the screen.
[G Pad 8.3 Original Android Development] GXGOW:
For some reason, TWRP gets stuck when I try to reboot back to the system, so I always have to force-reboot my tab after I flashed something. Is anyone else experiencing this too?
[G Pad 8.3 Original Android Development] fefifofum:
Screen timeout is like a screensaver, the device doesn't enter any kind of sleep mode, so updates (or any other activity) don't get interrupted. You don't need to unlock the screen for the update to finish.

I never experienced that. Where does it get stuck, in recovery or in splash screen? Since when do you have this problem? Maybe you could upload the recovery log, you can find it in /tmp/recovery.log.
[G Pad 8.3 Original Android Development] GXGOW:
The screen gets stuck when I try to reboot after flashing something or by going to Reboot -> System. I then have to force reboot the device for it to actually reboot.

I've copied the log from my device (check attachments)
[G Pad 8.3 Original Android Development] fefifofum:
So you flash anything, select reboot > system and it gets stuck, but when you force the reboot it works fine. Is that right? I never heard of that problem, and your log doesn't show the error. Did you try to reboot into recovery, to see if that works? Did you try formatting system and reinstalling your rom? And most importantly, since when do you have that problem, only with twrp 2.8.7.1, or also with previous releases?
[G Pad 8.3 Original Android Development] Wingchundub:
So now will be able to install trwp without the hassle of sdk?, this was over my head and i was only able to root my sons lg's.

If so i will read up as my boys are still on original firmware and would excellent to put custom roms on them.

Best wishes :good:
[G Pad 8.3 Original Android Development] Deltadroid:
I think the problem is that, at one point, you had a bad flash which has left your boot or recovery partition with some dirty bits at the end of the flash. The solution is to zero out your boot and recovery partitions and put the boot and recovery images back on a freshly zero out partition.

These commands will zero out your recovery and boot partitions. Make sure you also use the dd command to flash the boot and recovery image back on before rebooting.

adb shell su -c "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/recovery"

adb shell su -c "dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/boot"

Copy boot.img and recovery.img to your device, and change to the directory with the image files.

dd if=recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

dd if=boot.img of=/dev/block/platform/msm_sdcc.1/by-name/boot

Hello, in the instructions, it says that "Note: Fastboot install is for Google Edition only".

But, if my V500 has the 5.1.1 AOSP, can i use this method ? Because i can't no more get into TWRP since i have this message when i try to enter into recovery : "Secure booting error : Boot certification verify in recovery mode" since i installed the 5.1.1 rom.

Thank you !
[G Pad 8.3 Original Android Development] fefifofum:
Doesn't matter what rom you have, your v500 is not the Google Edition model so you cannot use the fastboot method. Download the latest image and flash it with THIS APP (requires root), or use the dd method from terminal.
