Sprint lg g pad f7.0 (lk430)

[JimiGEE]

I just rooted with KingRoot. SuperSu will not work as it states the binary needs to be updated and fails to do so. Once KingRoot is uninstalled, it appears to lose root access. I just left KingRoot installed as it acts like SuperSu anyways when something is asking for Root access. Still no recovery, i saw on a different thread a process for another G Pad 7 (mine is lk430) but now I basically have no recovery long story. Anyone have success yet with a custom recovery?

 

[hank00]

I'm in the same boat as JimiGEE above. I took a few bad steps in my root process and now I'm looking at "Life's Good" for eternity. I'm not knowledgable on the recovery process, though I've tried the recovery tool to no avail. After reading this thread, I know why.

I did find the Chinese forum that was referenced earlier. It looks like the software that we need is located there, but it can't really be readily downloaded. I even went as far to create an account, translate everything, but downloads are earned, not just given.

I can only be so bummed. This was my own fault. : (

Ugh

Pretty much in the same boat as everyone else looking at the LG logo forever. Completely frustrating. If anyone is able to find the KDZ files or an image that actually works they will be my hero forever

Same thing happened to me,, but on the spark screen. But how i got passed it was to remove the sim card and sd card. But i have to do that every time i reboot.. A bit frustrating but, a temporary fix i suppose.

ok i just read this entire thread.....
i used king root 4.6.5 to quickly root this device. my friend brought it over and had to leave suddenly so i didnt get to replace king user with super su like i usually do. the next day he came over and said something was wrong with the tablet and pretty much all google services framework, playstore, gmail. etc...are no longer present on the device....i traded one of my unlocked/rooted phones for the tablet and now it belongs to me. so, of course i am immediately in search of recovery img ...nothin...custom rom is obviously out of the question...so now, like u guys, i am in search of a way to flash stock rom....ill get back to that though
real quick i wanna mention the supersu me app everyone uses to purge kingroot and install supersu....DO NOT USE IT. i encountered a similar problem with alcatel where everything was fine until i used the supersu me ap ....bricked. so after that i found a different method that works very well and is probably the reason my device is not bricked. here is the link--http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html
download the simple zip file and keep it on sd card...when u root a device and need to purge kingroot simply extract the contents of the zip to the root of internal storage and run terminal command sh /sdcard/mrw/root.sh it runs the script and next thing u know your updating supersu binaries ....people need to stop using supersu me app period!
--so back to the restoring stock firmware issue. someone posted about doing a titanium backup of all the apps on a fully functional gpad and sharing it with us...that would be cool! but still we need a way to flash the original firmware and it looks like no devs are trying to do it. at the beginning of this thread there is a link to the source code from lg. i downloaded one of the files and extracted the folder. in that folder was a readme file that looks like it is explaining how to use the contents in the folder to build the android rom....this is what it says

1. Android build
- Download original android source code (android_5.0.1) from http://source.android.com
- Untar opensource packages of LGLK430_L_Android.tar.gz into downloaded android source directory
a) tar -xvzf LGLK430_L_Android.tar.gz
- And, merge the source into the android source code
- Run following scripts to build android
a) source build/envsetup.sh
b) lunch
c) make
- When you compile the android source code, you have to add google original prebuilt source(toolchain) into the android directory.
- After build, you can find output at out/target/product/generic

2. Kernel Build
- Uncompress using following command at the android directory
tar xvzf LGLK430_L_kernel.tar.gz
- When you compile the kernel source code, you have to add google original prebuilt source(toolchain) into the android directory.
- Run following scripts to build kernel

- cd kernel
- export ARCH=arm
- export TARGET_PRODUCT=e7iilte_spr_us
- export CROSS_COMPILE=../prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi-
- make e7iilte_spr_us_defconfig
- make zImage

* "-j4" : The number, 4, is the number of multiple jobs to be invoked simultaneously.
* lz4demo : More information can be found at "https://code.google.com/p/lz4/"
- After build, you can find the build image(zImage) at arch/arm/boot

3. how to build chromium38_lge (vendor\lge\external\chromium38_lge\src),
please refer to README.txt at the folder mentioned above.

i lack the experience of pulling off a procedure like this, but i have the patience and intelligence to learn how to do it. just like everything else....i taught myself with google, lol. seriously though im sure there are some devs on xda that know exactly how to use that readme file and the source code files to make a flashable kdz file we could use to fix our devices....im going to try and learn how to do it myself, but hopefully someone more experienced can save us all some time

also, has anyone even tried to flash the recovery file from gpads from the carriers that do have twrp recovery and cyanogenmod? i know with other devices u can flash virgin mobile rom onto a device that is boost mobile, and it works fine because is it still the same device....i dont know why there is no development on the sprint version of this tablet , but we gotta figure this out

So the method detailed here for using kingroot for root access then using terminal emulator to install supersu and deleting kingroot works. It also works on the Amazon fire 7 2015 model.

This whole process takes about 5 minutes.

I wish there was more development on this tablet since it is basically an embiggened LG Volt and it's gsm counterpart has marshmallow ugh i guess you get what you get for free service as of now i just have it rooted..it is activated on RingPlus for free 1.5 gb per month

 

[gershee]

Accidentally corrupted mixer_path.XML in system/etc

[Kolczyk]

LK 430 soft brick

I too am stuck at the spark screen. I would like to get back to the stock rom but have frozen and deleted some system apps. Can't find the ROM online anywhere. Can anyone help? I have downloaded the SDK via Android Studio and I am stuck. I also rooted with Sume-pro...

Fixed my Lg LK430!

I stumbled across a site this morning on google which hosted the stock rom for the LG LK430.

Website with the 430 TOT zip.

The above file contains two files:
lgup_etablet.dll
LK430ZV4_11_User_Secure.tot

I used the LGFlashTool:
Select Manual Mode..
DLL: lgup_etablet.dll
S/W: LK430ZV4_11_User_Secure.tot
Action Mode: Board DL

I'm not going to tell you how to flash.. you can find many tutorials on it.
Example Tutorial (Scroll to the .TOT part)
Another tutorial on flashing..

Remember to use Action Mode: Board DL!
The first time I flashed I used Upgrade DL as the action mode, which put me in a boot lock on a screen that said "factor reset status 2".
The second time I flashed I used Board DL as the action mode, which booted me into mini os.

At first I thought Mini OS was just another bust because I couldn't do anything and it kept booting into a screen where it displayed two QR codes (barcodes) in the top-left corner and bottom-right corner and the top-right corner said "PASSED" and bottom-left said "PID". If you come upon this screen its possible to return the previous menu where you can choose to boot normally. I had to do some google searches but the way to interact with the menu options is to hold the power button down then click the button "Normal Boot" option. A popup window will appear with NO and YES buttons, same deal, hold down the power button then click the YES button to boot normally.

FYI: I was stuck in the mini os boot for a bit so before I managed to click the normal boot option I did a factory reset and cleared the cache. (I don't know if it made any difference though).

So long story short, I managed to fix my LG LK430 -- which has been disabled for a good many months.
And all the thanks goes to the person who uploaded the stock rom @ http://www.rwilco12.com/

Thanx so much for this ive been looking for literally months on how to fix this thing to no avail till this i couldnt thank u enough for the info it worked like a charm

 

[runt]

Power + Normal Boot doesn't work for me, anyone have a suggestion on what I can do to fix this?

<edit>
Somehow I managed to go back from the PID/PASSED screen and then I could do it.

sorry if this is the wrong place for this, there just isn't much of a community online for this particular tablet

I got a lk430 through freedompop via a groupon, I had been looking for a cheap wifi tablet for the kitchen for awhile but I figured, why not snag this up as it fit my basic functionality needs, syncs well with my G4, and could act as a backup if I lost my phone and do other light work out of the house on the free plan. Overall im very satisfied with my purchase, I just wish I could free up some more space on it but it's you can't move a lot of apps to sd card anymore without root. (i'm also hoping to trick it into thinking it has a bit more ram via root and sd partition so it doesnt constantly reload web pages when switching windows but that's secondary)

So is there an actual safe way to root this tablet, people seem to say stay away from king root, and it seems like a lot of people have been bricking them. Is there recommended way to root this device on 5.01 or is it better to downgrade to 4.41.

Is this the kitkat firmware or the lollipop ?

 

[mofeed altayeb]

I updated my g pad using the firmware you sent
It works good but i lost hotspot and bluetooth tethering which i use a lot
Is there any way i could have them back or a link to the previous rom lk430ZV3 ?

 

[fh8]

a link to the previous rom lk430ZV3

Seconding this because ZV4 will not allow the necessary steps to fix that Lollipop memory leak.

 

[donyjunk]

Is the memory leak fix that you are talking about this one on the Google play store?
fixlollipopmemoryleak
ZV4 pushed (oct 2015) after the publish date for this (april 2015) so see how it might fail unless the memory leak fix was updated.

This module was developed by tonyp, and it basically just adds the Color Fade-related bugfixes that Google applied in Android 5.1 to devices that are currently running Android 5.0 or 5.0.1. These same bugfixes were applied by manufacturers and custom ROM developers in their initial 5.0 builds, so only devices that run stock Android need to worry about this issue.

ZV3 and ZV4 are 5.0.1. People have been complaining about sluggish performance and high memory usage and a few people who've tried the fix say their LK430s seem to run smoother, so I'm very skeptical of that last sentence.
