Need 4.4.2 firmware?

[Guide] Return-To-Stock [V400]

Need recovery?

[RECOVERY][UNOFFICIAL] TWRP 3.1.0-0 (+legacy) for v400 aka LG G Pad 7.0

Want to compile yourself from my sources?

Setup Android build environment -> https://source.android.com/source/initializing

Open up your terminal and initialize the repo:

$ mkdir lineage
$ cd lineage
$ repo init -u git://github.com/LineageOS/android.git -b cm-14.1
$ git clone -b cm-14.1 https://github.com/MyczkowskiAdam/local_manifests .repo/local_manifests

Now sync repo:

$ repo sync --force-sync --no-tags --no-clone-bundle

Once syncing is finished all you have to do is build:

$ source build/envsetup.sh
$ brunch v400

Once build has finished go to out directory:

$ cd $OUT

and flash lineage-14.1-*-UNOFFICIAL-v400.zip onto your tablet.

:good:

Wifi Not Good and don't work
[G Pad 10.1 Original Android Development] amdev0101:
Everything works fine on my tablet.
[G Pad 10.1 Original Android Development] Alias X:
Well, the problems are identical to these of slim:

Camera (obviously)

Wifi doesn't connect automatically (but it does manually)

YouTube 60fps

The performance is a bit worse, I'll probably test another launcher than Trebuchet and Google Now.

Off topic: Is there a place where I could download the apk of the new Lineage Gallery? Looks quite nice.
[G Pad 10.1 Original Android Development] amdev0101:
Camera is a WIP, YouTube is related to kernel, and I will look into wifi bug.

Tho this will be in the next two months as my GCSE exams start in May so i have very little time to start revision.

Tho, eventually we will get it resurrected ?
[G Pad 10.1 Original Android Development] DaRk_dOg:
Really thank you for your time and effort.

The builds feel a little less fast than the CM13 nightlies I was using before (but nothing that cannot be handled by lowering the transition speed)

Keep it up!
[G Pad 10.1 Original Android Development] amdev0101:
Android Nougat isa bit heavier especially for older devices that use msm8974 HALs, but these builds are still faster and smoother than official nightlies will be due to Cake-Kernel brought by Paul Keith :)
[G Pad 10.1 Original Android Development] DaRk_dOg:
You're right, expecting more from this old device would be foolish. The latest build is working nice for me in daily use basis ;)

Hello, i tried this rom for a few days but unfortunately there is a wifi bug. When i leave the tablet and go for a few minutes and come back, wifi shuts itself and you need to turn off in the settings and turn on again. This is little bit annoying and i deleted the rom because of this problem. It'll be so good if you fix it very soon and i'll install it again because this rom has a great battery life.

Thanks!

whats the status on lineage os 15 is it working yet
[G Pad 10.1 Original Android Development] amdev0101:
Is anybody else experiencing incorrect battery reading so it drops down to 1% even though battery is like 80% or is it just that fact that i might have damaged the connectors?
[G Pad 10.1 Original Android Development] googlephoneFKLenAsh:
I experienced incorrect battery reading in the past randomly but not down to 1%.

Sometimes, battery would only charge to about 80% and then after reboot it would show something around 30%. I don't think it's because of bad battery. It's just the rom has issue with correct battery reading.

I didn't see this problem in the past 2 months.
[G Pad 10.1 Original Android Development] amdev0101:
Then I must have damaged my battery connectors when fixing the tablet, ehh
[G Pad 10.1 Original Android Development] williambright80:
i think mine does that too or lg has a secret turbo moe that charges it 20% in 5 seconds lol but i was on stock too so...
[G Pad 10.1 Original Android Development] jason2678:
My battery has always been a little funny on custom roms, but the actual life has never been bad. Sometimes it only charges to ~80% when left on overnight. Sometimes it stays at 100% for a few days even with some mild use then suddenly drops to 30%. Actual standby and screen time are fairly consistent, but the percentages reported seem a little suspect occasionally.
[G Pad 10.1 Original Android Development] williambright80:
what about android 7.0/ did you have any issues
[G Pad 10.1 Original Android Development] jason2678:
Just that nougat seemed to get a little laggy. For that reason, I've mostly kept this tablet on lollipop.

How to re produce WiFi problem

Dead guys, I want to thank you all for the good work done. However, I want to provide my contribute.

Regarding the wifi issue, I think I've found the way to reproduce the issue and (maybe) help somebody di fix it.

At home I have a dual band access point (2.4GHz and 5GHz). If on the LG G PAD 7 (v400) I register to the 5GHz signal, sometimes the device disconnects and the only way to reconnect it is to manually go in wifi settings, search for networks and manually reconnect to the 5GHz signal.

However, If I delete all known networks, and I register only to the 2.4GHz signal, the wifi is perfect. Also coming from sleep the tablet is still connected.

Only rebooting it I have to manually reconnect to the wifi.

If this can help I would like to suggest a fix that was done for oneplus2 review.lineageos.org/#/c/198597 regarding wifi issues similar to our problem: in some situations, the system was configured to manage 5GHz frequency with higer priority over 2.4GHz. Maybe this bug is similar to our situation.

Please tell me if I can help with more info or anything else.

Thank you
[G Pad 10.1 Original Android Development] bedwere:
I have only one network at home and that's the only one the v410 is registered with. Yet the device disconnects.

As suggested on the Lineageos web site, I edited /etc/wifi/WCNSS_qcom_cfg.ini and changed the line:

gEnableSuspend=3

to:

gEnableSuspend=2 ,

but it still disconnects after a while. :confused:
[G Pad 10.1 Original Android Development] williambright80:
even when i wasn't on the 5 ghz it would still do it it also does it on the 2.4 ghz band too but maybe it might work the wifi bug wasnt present in the other versions
[G Pad 10.1 Original Android Development] surricani:
Dear guys,

I overridden the file in the system partition (avoid to rebuild the whole image for change only a single file) and I have to say that after one day I can't reproduce the issue of wifi disconnecting.

Plus, If I restart the device it automatically connects to wifi.

It is stable for both 2.4 and 5Ghz.

Please, can you also try this change?

Regards
[G Pad 10.1 Original Android Development] nicospanas:
Hi, could you please give details as to which file and how to do it exactly, to a noobie? It would be amazing if it would finally work.
[G Pad 10.1 Original Android Development] jason2678:
Seems to be working for me. I made the change last night, and WiFi survived overnight. It doesn't seem to automatically connect after a reboot, or it's very slow if it is trying. It does seem to maintain it's connection once it's connected once, though. A definite improvement. :good:

OK, so it disconnected again overnight tonight. It's still better. It's not disconnecting every time it goes to sleep, but it's not 100%. Also, it seems like every time my tablet flakes out it kicks everything off my home network. Maybe it's a coincidence, or something unique with my router. Anyone else seen this?
[G Pad 10.1 Original Android Development] jason2678:
I did it in recovery with adb. Boot into twrp and connect to a computer. In twrp go into Mount and tick system.

Then, in a terminal on the computer:

adb pull /system/etc/wifi/WCNSS_qcom_cfg.ini

That will pull it through to your computer. Use a good text editor that won't mangle the line endings. Open the file in a text editor, find:

gEnableSuspend=3

And change it to:

gEnableSuspend=2

Now use the computer terminal again to push the modified back to the phone:

adb push WCNSS_qcom_cfg.ini /system/etc/wifi/WCNSS_qcom_cfg.ini

Then, just to make sure the permissions are still right:

adb shell chmod 644 /system/etc/wifi/WCNSS_qcom_cfg.ini

Then reboot to system. It's a little clunky. If more people report success, I can probably make a zip to automate it.
[G Pad 10.1 Original Android Development] nicospanas:
Hi. Thanks for the info. At the moment I am travelling and I do not have access to a pc, only the tablet, so it will have to wait till I return home. Someone should merge it to the updates.
[G Pad 10.1 Original Android Development] surricani:
Hi,

my original post referred to changes applied for oneplus2 related to 5GHz/2.4GHz roam:

gRoamPrefer5GHz=1

gSelect5GHzMargin=5

I tried those two and I can say that in my case it works correctly.

Maybe we can also try to mix those with the suspend.

Regards
[G Pad 10.1 Original Android Development] bedwere:
I changed to

gEnableSuspend=2

in my mom's v410, but it still disconnects after a while.
[G Pad 10.1 Original Android Development] nicospanas:
Is there a way to do the change without the use of pc?
[G Pad 10.1 Original Android Development] jason2678:
/system is probably mounted read only when you're booted up so changes wouldn't be saved. I could be wrong. You can check it by entering this in a terminal app:

mount | grep system

In parentheses at the end of the line will be a bunch of info on how /system is mounted. If you see rw, you're good to go. If you see ro, you'll have to remount it to make modifications. Do that by entering this in a terminal:

su
mount -o remount,rw /system

If that doesn't return any errors, /system should be mounted rw now. Now you can use an app like Root Browser to change the configuration files in /system discussed earlier. That app provides RB Text Editor that should be good enough for making these small tweaks. When you modify anything in /system be very careful with permissions. Most files are 644 (rw-r--r--). Check permissions on anything you edit and make sure they are the same after the edit, just to be safe. Root Browser can check and set permissions from the menu you get when you long press a file.
[G Pad 10.1 Original Android Development] nicospanas:
Thanks directions are working.

---------- Post added at 03:30 PM ---------- Previous post was at 03:27 PM ----------

[G Pad 10.1 Original Android Development] jason2678:
Did you add those lines? Checking that OP2 commit on the LOS gerrit it looks like they deleted them. I haven't checked yet, but guessing from nicospanas' post a few below yours, I'm guessing they aren't currently present in the V410 default configuration.

Is it possible to include this change to our device so that we can have a working IR remote?

Off the shelf apps will never work because like Adam said, there's some stuff missing. Try the method I linked to, might work, but do make a nandroid backup beforehand (of course)

If you don't want to try the above, you could try the Peel app, there's a chance it will work out of the box. It did for my LG G3 phone...
[G Pad 10.1 Original Android Development] PaideLis:
Ok, I will give it a try when I have my tablet again (I'm on beach now :laugh: )
[G Pad 10.1 Original Android Development] googlephoneFKLenAsh:
Sure it won't work for our device directly without adding proprietary codes.

It is confirmed working on the LG L90 device, which has almost identical hardware as V410.

Maybe we can use this change as a base.
[G Pad 10.1 Original Android Development] amdev0101:
Yeah that's what I mean, its to be worked on, bofore I started my break we had a quick look at it and iirc it seemed like the ir dtb was incorrect not 100% but it definitely wouldn't start correctly

is anyone else here having really slow response with 14.1?? I am still not able to get WiFi to stick
[G Pad 10.1 Original Android Development] googlephoneFKLenAsh:
Yes.

Based on my experience with multiple devices with custom roms, LOS/CM 14.1 is slower than old cm13, but LOS 15.1/ android 8 Oreo is much faster than any previous versions, especially with Android Go which is optimized for devices with 1gb or lower memory.

Wish v410 can get LOS 15.1, which will definitely bring a new life for our device.
[G Pad 10.1 Original Android Development] williambright80:
we need new blobs
[G Pad 10.1 Original Android Development] ericcl:
I had the wifi problem for the longest time, going back to the ROMs prior to the official builds. Any time the device idled for more than about 20 minutes, I would have to reconnect wifi. Sometime in January, the releases started holding the wifi on for days at a time. I generally update once per month to get the security patches. I don't know if it was a deliberate fix, a side-effect of another fix, or some happy circumstance.

I've finally tired of it being a dog, so I am reflashing this evening minus GAPPS. Going to use fdroid and microg for what little Google services I need on a tablet.

[G Pad 10.1 Original Android Development] aaronDroid80:
So I've been reading, and the threads for this device are somewhat of a cluster. I recently picked up a V410 and it came with 5.0.2. From what I've seen, it looks like the only way to root this thing is to downgrade to KK, but a lot of those posts are very old. Was there ever a means to root LP found?
[G Pad 10.1 Original Android Development] nicospanas:
Some people rooted it with kingroot, but it is not recommended. But even if you do, you cannot flash a custom recovery or any other custom rom. I have done the downgrade, without any knowledge, just by following the very detailed steps, and was successful. I now run LOS.

However, most of the custom roms like CM or LineageOS are a bit buggy for v410, so be prepared. Check also this thread: https://xdaforums.com/g-pad-10/help/stable-rom-lg-g-pad-7-0-v410-t3705780/page2
[G Pad 10.1 Original Android Development] jason2678:
You have to downgrade to the KK bootloader if you want custom recovery/roms. If you choose to downgrade I would not recommend messing with the test KDZ for the V410. It messes up the internal storage and it is a fairly long process to get it back to normal. Users have found a KDZ for the V411 that works for downgrading the V410 too.

Kingroot will root stock LP. Don't try to replace Kingroot with SuperSU if you do. That has been reported to brick this tablet. The only guy left who seems to be interested in maintaining LOS for the V400/410 has said he'd like to get the LP blobs. If you do happen to root 5.0.2, a system dump might be helpful. This should pull it:

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

I can not copy files from my pc to v400's sd card because the copy process stops after a few seconds.The sd card works fine with my mobile phone.Is this a problem of the rom or i need to change some setting value at my tablet ?

Has the wifi issue been solved? Actually I have G Pad 8(V480), but both devices seem to have the same problem.

The commands below will fix the issue that wifi doesn't connect automatically. Please try it from TWRP console or adb.

cd /data/property

chmod 000 persist.sys.timeadjust
chcon u:object_r:system_file:s0 persist.sys.timeadjust
