[G Pad 10.1 General] landj9697:
I'm hoping someone can help me here. I had to force myself to step away from the tablet today before I make things worse and brick it. I rolled back stock Lollipop to stock KitKat and them installed CM13 and TWRP. I did not read the part about the vertical lines issue until I had played around for several hours trying to figure out what was wrong. I would love to try the 'aboot' fix, but the vertical line issue is so bad that it is messing up my ability to see TWRP, so I can't do anything about it. The device will boot into CM13 just fine, and everything seems fine other than the lines. I've used Flashify to try to reflash to several different versions of TWRP to no avail. I reboot to recovery and I can tell that it has loaded because if I tap the screen I get the haptic feedback that you get when selecting buttons in TWRP. However, there is nothing on the screen but vertical smears.

I this point, I'm not picky. I would either like to be able to get rid of the streaking and use CM13, or I'd like to get back to complete stock Lollipop (also without the lines...lol).
[G Pad 10.1 General] landj9697:
Please disregard. After stepping away a bit and clearing my head for a while I went back at this and downloaded a fresh copy of TWRP 2.8.5.0 and used Flashify to flash and reboot. I don't know if it was the fact that I had never gone as far back as 2.8.5.0 or what, but this time it loaded TWRP clearly and without the smearing. I quickly hooked it up to my laptop and ran the 'aboot' procedure and it fixed it completely. I am now a very happy camper!

Thanks so much to marcsoup and navin56 for the vertical lines fix and of course fatbas202 for the ROM.

Nice work! Just went through the whole tutorial all from the tablet and the terminal in twrp in an hour or so. Kind of a pain but I had a child to look after that wouldn't put up with me sitting at my desk :eek: Worked perfectly, 16 GB showing on Candy5 and no white lines! A big thank you to fatbas202 for being so dedicated and marcsoup for the white line fix!

device not found adb shell-semi noob here

ok so knowing even the smallest thing can cause a problem ill say everything i did leading up this point....

first off tablet was on 5.0.2 i rooted with kingroot

installed twrp with flashify just to figure out duh it isn't supported on stock 5.0.2 got the whole certificate error thing just rebooted everything was fine

then today i found this thread thank god (flashing tabelt for nieces b-day)

i had previously had the small adb package installed which just had fastboot and adb with dlls but i wanted to follow this guide to the mother Fing T so i have installed android sdk and everything else (i had some trouble with debug mode being greyed out this may be the problem) i have advance to the part where i need to enter the commands in to adb shell while in recovery

i noticed commands did nothing so i did devices command and it show that there is no device

i have tried all 3 of my usb ports multiple cords and even switching between drivers (adb device) & (android composite ADB interface )

and in my devices its showing up as MTP under multimedia devices would this be correct ?

ty for any help and also TY OP for this tut

i haven't flashed anything since my galaxy s3 bootloader was locked up ......

///////////////////////////////////////////////////////////////////////////////////////////

i was able to find my device disabling mtp in twrp i followed the steps and at the flashing process i got /data errors, from not having data mounted i guess well when it rebooted it was still on 4.4.2

i looked around and i was told to do a factory reset in twrp and re flash so i did i still couldnt mount and still go those errors but this time i got the candy5 working yay right... actually no it works in all but there it doesnt think i have a sim card and almost every app besides contacts and flashify wont work it crashes i can even use the keyboard ..... sooo yeah just gonna wait for u guys to help me lmao im close enough to bricking it sooooo..... yeah quit while im ahead right ?
[G Pad 10.1 General] BlastMeOblivious:
Did you erase or flash any partitions other than userdata and grow? When your look at the partition table is it labeled userdata and type ext4?

When I did mine I had to change the process a little because I was doing everything from the terminal right in twrp and it wouldn't flash candy5 until I ran the make2fs command
[G Pad 10.1 General] Pktmouse:
i did nothing the deviated from the guide besides the factory reset i copy and pasted every command in to the adb shell just to make sure i didnt type anything wrong and i have yet to be able to find my device again in adb to check if it is now ext4 because i had to make it ext2 cuz "the tool only supports ext2"

i just wanna than you in advance for anything u say that may or may not help any input is good....
[G Pad 10.1 General] infamousvincci:
Hi,

I am trying to follow the instructions,

I have to stop after:

TWRP: unmount data... uncheck the data.

After that, Im lost. Where do i type those commands like

cp /sdcard/parted/sbin/??

I tried typing it in the terminal emulator inside TWRP but seems like some commands are not working.

for example, 'p' which prints the partition table. and rm 34 and rm 33 which produces error (no file or directory)

Im so lost. Im sorry im a newbie.

Where do i go type those commands and how do i get there?

Thanks in Advance
[G Pad 10.1 General] Pktmouse:
if u are connected to the pc hit windows key+R it should open run window then type in cmd and hit run when the cmd window opens type "adb shell" with out quotes and hit enter you should be ready to start entering commands

i really hope this helps and maybe some karma mite rub off and i can getsome help with my problem

sdcard file/directory not found.

If you are having trouble doing the white lines fix and getting "adb Shell" to connect to TWRP Here is how i got it to work

1: install the minimal_adb_fastboot_v1.1.3_setup.exe file from the same tutorial link where you get the "parted" file to fix the data issue.

2: Adb shell wouldn't connect to TWRP and gave a "closed" response so i just adb shell when i was connected after my phone booted up.

turn on usb debugging and connect usb cable then open Minimal adb Fastboot and type "adb shell"

3: Type "su" to get superuser rights. or you will get a permission error

4: do step 4 from original directions "`ls -al /dev/block/platform/msm_sdcc.1/by-name/` Let's make sure we are flashing the right partition. On my device "aboot" is /dev/block/mmcblk0p6. You should verify this on your device or you WILL brick your tablet."

5: For some reason i got a "/sdcard/aboot-fukt.img: cannot open for write: No such file or directory" error

I had to use "dd if=/dev/block/mmcblk0p6 of=/storage/external_SD/aboot-fukt.img" for it to work correctly

6: "dd if=/storage/external_SD/aboot.img of=/dev/block/mmcblk0p6" This got it to work correctly.

7: In Adb type "reboot" to reboot your phone and you should no longer see white lines.

Sorry if its confusing or poorly formatted i suck at explaining things but i wanted to share in case anyone else was stuck.
[G Pad 10.1 General] joeclark:
Ok, I am not sure what I have done wrong here. This all started when my tablet tried to install the 5.0.1 update. It force installed my rooted tablet that was running twrp. It if course did not work. I FINALLY got it fixed and updated back to stock 4.4.2 and tried to instill the update but it would not go. Even though I had completely untied my device, in download/firmware update mode it says it is still rooted, there for it would not install. I have up on the update and set up my tablet as I had before. Now after several days(and finally back to pre issue point) I picked up my tablet to be looking at the TWRP screen again and my system file is empty and I can't find my extsdcard in TWRP to reflash 442. What the heck is going on. I did not see a notification for the update so what happened now?

I swear if my Nexus 7 was LTE or was larger than 8gigs I would not be dealing with this.

Run the commands in step 29. Be sure that you run the correct commands depending on what OS you are booted into (Android vs. Recovery).

[G Pad 10.1 General] _xttandroidgamer:
Help?

Hey. I've gotten to the step where you have to create the new partition and rename it at 33, all went well.

As you've probably seen by now Candy5's site is down so you can't download their rom.

I said eh, why not just replace it with CM12 for V410.

OHHHH boy did I make a mistake

Flashed it, seemed to work fine other than errors about not being able to access /data or /storage as such.

Tried wiping and re booting the tablet, and all I get is the LG logo and a nice beautiful white-line dance party.

Any ideas on how I can fix this if at all?

*UPDATE*

I got the tablet working. I apparently deleted /data and needed to fix that, for anyone else with this issue:

Boot into twrp.

Open on windows ABD and Fastboot minimal

abd shell

DO NOT COPY AND PASTE, EACH LINE MUST BE ENTERED ON THEIR OWN

dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img

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

exit

abd reboot

But for some reason, now those weird white lines are ENGRAINED into my screen whenever anything is dark. Any help?

:confused::confused::confused:

New problem | minor

Hey!

I wound up fixing EVERYTHING as stated above. Seems I wasn't looking infront of my face.

I tried flashing GApps and wound up in an even more bricked state. Could barely get into TWRP.

I accidentally somehow deleted the internal storage on my entire device (whoops.)

I had to reset something (I can't recall it's been 24 hours of this nonsense)

in TWRP's factory reset thing, and the internal storage came back!

Flashed CM13 and all is smooth.

Except for one thing. (Of course.)

Those white bar animations seem to me all but drawn into my display, On the black parts.

Like whenever the pixels have to go dark (notification bar etc)

You can see a bit of those bars in the back.

This makes viewing weird and awkward.

Anyone have a fix that isn't too complicated for this? I don't wanna have to go through all of that again...

[G Pad 10.1 General] fatbas202:
The white line fix is in the OP. They will stay on the screen for a long time, but will go away eventually. I thought I screwed up my tablet at one point, but eventually the lines faded.
[G Pad 10.1 General] fatbas202:
The fix for the white lines is in the OP. They will fade eventually. Just leave your display on for like 30 minutes.

step#25 help please

In step #25 you say that your partition starts and ends at a certain point(ours may be different) but how do we know if its different? And how do we know where ours starts and ends? Also i am aware of the fact that this is an old thread so i hope you are still on here. And also thank you very much my tab was bricked till i found this thread and now the only prob is the internal mem fix. And is the parted that we are making chmod +x an android program? Or for windows? Meaning can i use parted from twrp terminal and not have to plug into a computer?

---------- Post added at 12:34 AM ---------- Previous post was at 12:21 AM ----------

I have 2 lg gpad 7.0 v410 the one i am currently on wich has been through the steps from OP and is now cm12.1 with twrp but i also have a 2nd gpad 7.0 v410 that hasnt been modded at all so if you could instuct me on how to extract the firmware i would be glad to help. ( aperently both the 7.0 and the 10 are both v410? As i had no idea that this was in the 10 thread until after i followed the steps to downgrade and root lol worked fine)
[G Pad 10.1 General] fatbas202:
Step 25 relies on the output of step 24 where it prints the partition table. If you are unsure but your device is an LG 7.0" V410 with an AT&T logo then you can just use the numbers that I have and you *should* be ok. The binary 'parted' is a linux program that runs on your tablet, so you can run this from TWRP. I *very* strongly recommend that you plug in your tablet and run everything over ADB because several people have bricked their tablets by mistyping things in the TWRP terminal.

If you have a 10" tablet then I cannot help you. I don't have one to test with. I'd be very cautious as to what you flash because I doubt the 7" firmware will run on the 10" hardware.
[G Pad 10.1 General] jazzespresso:
well, I am not sure how to extract lg gpad 7.0 v410 offical firmware (android 5.1, right?). Only thing you can do so if you rooted, take backup using custom recovery (TWRP), and upload files...keep in mind, TWRP creates data files, you do not need to upload data files, but need to upload all others.... if I have that I can maybe able to put together firmware....still not sure..

I have kind of gave up finding offical 5.1 firmware lg gpad 7.0 v410, no one has it...:crying:

Download mode

I completed all the steps exactly as OP said. After that, I did the white line fix. When I boot into system or recovery, the white lines are gone, as they should be. However, when I select "reboot bootloader", I am met with a black screen with a few white horizontal lines flashing across it. If I use the "reboot bootloader" option in ROM Toolbox, it reboots normally. When I reboot by holding volume up and plugging into PC, it boots to a black screen. When I used parted and flashed aboot, I used the twrp terminal. I am reasonably sure that I spelled everything correctly because my device works. It is just download mode having problems.. Should I use adb and redo the flash to be sure? Also, I edited /persist/rct/rct.cfg to say "Not rooted". Could that cause any problems? Thank you for making this thread, by the way :)
[G Pad 10.1 General] fatbas202:
Feel free to make a video yourself!

But seriously, if the instructions are too complicated then you are better off not attempting this procedure because you will probably brick your tablet. And you cannot copy and paste from a video like you can from a logical and plainly typed step-by-step guide telling you exactly what to do.

A lot of people have requested videos and zip files. I do not have 20+ hours to devote to building and testing a zip file. And I'm not a videographer. If someone wants to take this on, great. But I don't have the resources to build that sort of thing for free right now.

HOWEVER, I do have the time to answer intelligent and well-researched answers from people who will put in some sweat equity to trying to understand what needs to happen on their tablet and why. If you try to learn why you need to run these commands and get stuck, either myself or one of the other fine people that frequent this thread will certainly help you.
[G Pad 10.1 General] fatbas202:
Hey,

The white lines fix is just a hack that was put together by an observation. Since they are binary blobs, I don't have the ability to see exactly what they are doing. Long story short, I don't know. On my tablet the only time I got the white lines was during the boot animation. All other times the screen did what it was supposed to do. marcsoup noticed that these older versions of these partitions caused the white lines to go away on boot so we are flashing them here.

It may be reasonable to flash the aboot partition from the KDZ to see if you have white lines in the bootloader. I just don't know enough about what is going on with it to be able to tell you definitively what to try.
[G Pad 10.1 General] fatbas202:
That sucks. It sounds like something malfunctioned while it was flashing the MMC. You can try to get back into the bootloader mode and run step 6 again to see if it will be recognized.
[G Pad 10.1 General] BeeWall:

Maybe try rebooting into the OS and then twrp? Also, there is a white lines fix at the end of the op. You don'have to be in twrp for that, you just need USB debugging for adb, or a terminal emulator if you want to type it on the device itself.

Huh. Maybe it flashed wrong or something... Also, if you do the white lines fix, could you let me know what download mode looks like? For me it is a flickering black screen, I'm trying to figure out if it is a glitch with the image, or if I did something wrong.

[G Pad 10.1 General] BeeWall:
I believe this was mentioned earlier in the thread. The 8GB is hardcoded into the rom. There is a stock rooted rom by timmytim here. The rom in the link is zip. If you want to keep the stock recovery but still show all 16gb, you can use flashfire, which does not need a recovery. You will have to get flashfire from play store, download the rom, open flashfire, click plus and select ota or zip, select the file, check the mount system rw box, click plus, choose wipe (leave the default wipe settings), long click and drag wipe above flash zip, and then hit the flash button. Or you can just use twrp :)

Fastboot mode

After flashing the KDZ, it appears that 'reboot bootloader'(terminal emulator) or "adb reboot bootloader"(adb) brings me to fastboot mode, not download mode. I have flashed the kdz several times to be sure. The restart options just lead to a black screen, so it may not be functional. I am testing it now. (I can still access download mode with the button combination, so this isn't the same as the "zero laf" method)

EDIT: I have confirmed that fastboot can flash recovery images, as well as the aboot image. However, after flashing the aboot, the white lines boot screen has been replaced by a flickering black one. Any ideas why?

EDIT2: After flashing the aboot image, I can no longer access fastboot. It appears one must choose between boot animations and fastboot...
