A couple of years ago, I'd fruitlessly rooted and installed TWRP, and all I remember for the end of it was that I went back into the stock launcher using the LG User Support Tool.
Earlier today, I thought of doing it again, found what seemed to be a reasonable guide on it (little did about the 10/20/a/b/etc things), followed it.
It turns out I was already rooted. So I installed TWRP, worked pretty well, no problems. Most of what I really wanted was to get rid of the stupid menu button and replace it with the multitasking button for almost every other device. I know CM lets you do that from doing it with previous devices, so I grabbed the most recent one just to test it.
While going through the welcome screen, it wouldn't properly connect to any Wi-Fi networks. Entering the correct password just changed the status to "saved", and it wouldn't connect.
I flashed another ROM, and the same issue persisted.
Could someone please help me to figure out what I did wrong? I'd really appreciate it.
The SM600 works well and has had various version of CM and now Lineage on. The last version to work was the nightly 20170302, which if i install works fine.
Both nightlys since cause the tablet to sit there on a black screen (after you tell TWRP to reboot), with nothing ever appearing. If you turn the tablet off after about 30 minutes , it goes in to a boot loop with a black screen then the samsung logo , then the black screen etc.
Whats changed in the nightlys after 20170302?
I have even tried an advanced wipe, clearing all file systems. Lost for new thing to try , and think it i a fault with the build
many thanks
Any one able to help, Is this the right location to post a question like this , or is the a more appropriate location?
Hi, I have the latest CM12 installed in my tablet, but I have a lot of issues, especially when installing multiple apps or if I try to change the Launcher. It gets into boot loop and there is nothing one can do but re-flash the rom, which is pretty annoying. It has happened to me already 3 times in a short while and I am thinking of flashing LineageOS. However, I hear it is still very buggy, especially the issues with wifi. So I would like to ask which is the least buggy Rom for 7.0 v410 or if there is a way to avoid CM12 from getting the problem with boot loop.
Boot loop has been caused when trying to change Launcher (because trebuchet regularly crashes), when installing x-plore file manager and in a clean flash when I attempted to install multiple apps at the same time. In all cases it got stack in boot loop, or would start only to restart after a while, endlessly.
Finally, I opted for LineageOS 14.1.
I had the 11-11 Nightly for some time and seemed fine. Today I updated to 25-11 Nightly. It feels maybe slightly laggy, but still checking it.
I have also installed "Best WiFi Keeper" app from play store and it generally keeps me connected. However, if connection is lost (e.g at restart or if I get out of range), I have to reconnect manually. I tried few apps for reconnecting but nothing worked. It appears that although the WiFi network is seen, the tablet cannot really re-establish the connection automatically.
I found Nothing stable yet.. In last few days, I have installed CM 12.1, same trouble.. I installed Tipsy and Tesle, unable to install apps from playstore. Tried CM 13 and Lineage OS latest build as you, Wifi Teathering and USB teathering not working and same problem with wifi connectivity. Keed posted if you find something better.. I shall too...
Tesla works great for me. I'm running a lollipop version that's still on androidfilehost; I'm not sure if GZR ever got updated beyond 5.1 for V410.
I've had CM 14.1 (long enough ago it was still CM and not LOS) on the tablet, and it felt like it would get laggy. That could just be from junk my kid installs though, but I don't seem to have that problem with Tesla.
I installed Tesla (Tesla-v410-5.1.1.High_Voltage.2.2.1-Release-20150902.zip from https://androidfilehost.com/?fid=24052804347807214) with open G apps but getting errors while installing apps from Play store(Some error code 963 - tried cleaning cache of playstore, play services download manager, removing google account and adding again - Nothing works). Same situation with tipsy. Any help?

That is probably what I'm running, I don't have my tablet right now. I think I flashed it with opengapps nano. I didn't have to do anything unusual to get play store to work.
Tipsy uses the same base as Tesla and Validus. Since it is persisting across multiple flashes and roms, consider formatting the internal storage if it isn't too much hassle, the TWRP wipe where you have to type "yes" to confirm. Sometimes some remnants in userdata that aren't touched by the normal system/data/cache/dalvik wipe cause problems like this and can persist the way you're describing.
Just make sure you have rom and gapps on an external SD or you have confirmed you can push files to the tablet in TWRP over usb via mtp or adb before you blank the internal storage.

I'm on Tesla, but it has the same base as Tipsy. I don't have data on the tablet so it isn't a 100% conclusive test, but it doesn't seem to work. The switch for USB tethering never turns on. Wifi turns on but never connects properly. My laptop does briefly show connection then disconnects with both USB and wifi tethering. It could be because there is no data connection on my tablet, but looking through dmesg on the laptop gives me the impression that something on the tablet isn't working right.

I'm on lineageOs 14.1 which is alright though the wifi issue is still there. However, someone may have found a solution, but I don't know how to implement it. Check posts 207, 210 and 215 in this thread: https://forum.xda-developers.com/g-...eageos-14-1-v400-lg-g-pad-7-0-t3583952/page22

Would you (or anyone who sees this) please tell me is it possible to flash TWRP if I'm on 5.0.2? Or must I downgrade first?
I'm rooted already. TBH stock is pretty solid and if the custom roms have too many bugs I might pass. But I would like to flash Viper4Android and don't think I've ever installed it without a custom recovery. Many thanks in advance.

I made the same question more or less, over a year ago here: https://forum.xda-developers.com/android/development/help-installing-cm-t3483074
You cannot flash another rom over lollipop and I've never seen twrp for android 5.0.2 for v410. I am not 100% sure because my question was a bit different, but I assume from the replies, that probably not.

Thanks. That's more or less what I thought. From what I'm hearing there are some bugs in the roms that no doubt aren't being maintained at this late stage so I think I'll stick with stock (would be nice to have a custom recovery though.)
Not that it matters (a year later) but lots of people root with Kingroot when there isn't another option and there's several ways to remove all the bits left behind and switch it to supersu.
Thanks again!
Well, I have a work around to stop wifi from disconnecting in lineage os. After that I did not know when wifi got disconnected and reconnected.
Just download E-Robot from playstore.
https://play.google.com/store/apps/details?id=com.bartat.android.robot
And set it to settings as per screen shot.

It works! Thank you so much! It seems the LOS developers have stopped trying to fix the wifi issue but it is important. The workaround even works at restart, with some delay, but it works!
Just to clarify to newbies like me, where ssid you have to put the name of the network you want to connect. I wonder if one can add more networks, so it can connect to any saved network according to where you are. You think that's possible?

That would be great.. I shall try.. if successful, I shall post results.
I have a uk410, the US Cellular variant of the v410. I tried the CM12.1 "stable" release cm-12.1-20151117-SNAPSHOT-YOG7DAO1K5-v410.zip found here (archive.org/download/cmarchive_snapshots), along with Open GApps nano for 5.1 (opengapps.org/?api=5.1), and quickly got the infinite rebooting issue.
I then switched to the Telsa ROM mentioned earlier in this thread (Tesla-v410-5.1.1.High_Voltage.2.2.1-Release-20150902.zip) found at androidfilehost.com/?fid=24052804347807214, again with Open GApps nano for 5.1 (build open_gapps-arm-5.1-nano-20180922.zip), and have been running it with no issues for two days. My wifi is connected, and stays connected (tested two different routers), Play Store and apps have been working fine, and no crashes so far.
I'm using TWRP 3.1 (twrp-3.1.0-0-v410.img).
Thanks for mentioning Tesla, @jason2678 !
So like all of you I was looking for a rom to install on this v410 7" tablet, and it looks like I should just give up or stick with 4.4.2 stock if I want to go through the rooting process.
Basically all the development roms end with the same problems, wifi dropping, hostspot not working, no ir blaster, volume problems, bluetooth errors, and several hundred posts about lolipop memory leaks crippling the tablet because of only 1gb mem.
So, I am asking all of you, is there any real reason to root it, besides going back to stock 4.4.2?
And lastly, is the stock 4.4.2 kdz image that is floating around a test version, and if so is there an actual official kdz image somewhere that isn't a test image?
Thanks...
CrDroid by far in my opinion. Lineage based, 7.1.2.
Also, e/ os has been unofficially released. No Google anything...an entirely new Google list operating system by lineage. It's lightning fast and runs magisk perfectly. It's basically like nothing you've ever seen before and if you look under LG g pad 7.0 on Android file host, go to the second page and click on the last user who goes by the name anonymous and you'll find the ROM there. I had no idea what it was until my g pad boot it up and I saw the e logo. I pretty much **** myself in excitement
I believe I've deeply messed up here. I was trying to update to 8.1 while keeping Magisk root and ElementalX, but now I've got various UI problems including the home and app switch buttons not doing anything, the cell signal indicator never shows whether I'm on any data network, and notifications never show up. I also get a pop up right after boot that says my device has an internal problem, when I open up the phone app it says that my device isn't supported but I can still make and receive phone calls, and the USB OTG is not functioning at all. Almost if not everything else is working.
I followed the instructions to the T (I'll post a link to instructions a little later) then installed EX but, I didn't have root. At one point I also forced the phone off when it was presumably setting up final things after the ROM switching reboot. After booting up again, several apps were crashing and the problems above came up, so I followed different instructions specifically for installing EX and Magisk, which only fixed app crashes and Magisk.
I'm thinking where I messed up is that I didn't make a Magisk patched boot image for 8.1 before installing it, but at this point I'm not sure if that's the problem. I don't want to wipe the user data partition, but I'd do it if I have to. I have backups of everything anyways.
I just figured out that I was having the same issue as Cristiano Matos, though my OTG cable seems defective. The type-C connection is not working in one orientation, so I'll just have to use it in the other. This thread can be closed. Sorry for my stupidity
Hey,
some days ago i went from 7.1.2 to 8.1. I haven't had any issues whatsoever.
For some reason tho it seems like there's something wrong since my bug isn't listed as known.
The first ROM i tried was RR 6.0, and i tried it 2 times with this ROM. Same bug, just like with crDroid 4.1 which im running now. I even performed a COMPLETE wipe and made sure to flash the latest twrp recovery.
Whenever I setup a displaylock (PIN/Pattern/.. except swipe which is default) the device freezes immediatly afterwards, becomes totally unusable so im forced to pull out the battery. Rebooting then takes me to the lock that was just setup but entering the code just freezes the phone again. There's no workaround so far - everytime it happend i had to go back to factory settings.
Since i need to setup a displaylock to install a certificate I could really need your help. Im thanking in advice :good:
Regards,
furi
