Probably you are not using the proper TWRP for the firmware on your phone ( https://xdaforums.com/lg-k10/development/mtk-portable-twrp-porter-t3536123 ).

Thanks for help about recovery ... i tried 3 times with supesu v 2.82 even after i downgraded to firmware from 2016 .. after installing rceuniv second time just bootloop ...
[LG K10 Guides, News, & Discussion] gottlasz:
There is one thing you can try. Just install rce_univ twice skipping the supersu install. If your phone boots up normally then the problem is with the supersu. If your phone goes to bootloop then there is something else during the preparing steps...

Or you if you are using the latest TWRP build (3.1.1) you can also test just by deleting a system app in TWRP (system app you would not use e.g. evernote or any google app) and try to boot up. If it doesn't boot up then again there is something wrong with the bootloader unlock process...
[LG K10 Guides, News, & Discussion] oblyvision:
I can confirm the only SuperSU that work for K8 2016 is v2.79 (201612051815). Above that it will bootloop (already flashed recovery 3 times, took 3.6 Gb of my bandwidth -_-).

Thus, beware not to update it via playstore.

Just wanted to say thank you... Your amazing explanation allowed me to root my LG K10. From the bottom of my heart: Thank you!!!
[LG K10 Guides, News, & Discussion] losoollenos:
Hi, partner, very good tutorial thank you very much !!!

I have tried to apply it on my LG K220ar and everything went well but in the end, after the message "corrupt system" the mobile goes off. The bootloader has been unblocked and TWRP installed correctly, and already having the message "corrupt system" entered the twrp and flasheo the rce ---> supersu ---> rce. I had no error or anything but it did not start, any ideas ???

Maybe testing a more updated twrp, I'm with the 3.02 ???
[LG K10 Guides, News, & Discussion] gottlasz:
Hi, i took a look into the kdz files of k220ar. Its very similar to our k8 and k10 so it should work.

However as you can find in our threads firmwares after 2017 febr. are not rootable 'cos after the february patch lg corrected the earlier mistake that the boot image is not properly checked during boot up so we had the possibility to root.

You should find a firmware that has a security patch date before 2017 february and flash that and try to root that.

If you were able to do so there is a description in the thread how to put a hybrid firmware on your phone so you can use the bases of the earlier firmware but the system partition is the latest.

Also i think you can give a try to my twrp porter for you model (you can find that thread here as well). I'm not sure if it works but in case it does you might have a more updated twrp.

Keep in mind that the twrp has to be ported for the exact firmware you are using on your phone (even the patch date matters!)

Let me know how it goes.

PS: If you already use an earlier firmware make a recovery log so i can take look at what goes wrong.

Anyways i found no firmware for the k220ar that is from before february however there are other k220 models that's firmware might fit your model.
[LG K10 Guides, News, & Discussion] losoollenos:
Exactly, I am with the version after February and I did not find the previous firmware anywhere either ....

If you indicate which of the others would be compatible I will (I am not very sure), but you would have to explain how, with lgup? do not recognize the device ...... guess for the dll, I do not know.

And if, by the doubts I will carry the last twrp to see what happens, thanks for everything !!!

I'll keep you informed :bueno:

Unlock boatloader lg k8?
[LG K10 Guides, News, & Discussion] gottlasz:
I have a guide for lg up:

https://xdaforums.com/lg-k10/how-to/flashing-firmware-using-lg-t3517839

As for the other firmware:

https://lg-firmwares.com/category/lg-series/lg-x-power/

i believe the k220z or k220h firmware might work (from before 2017 february). You can test it by flashing it via lg up.

In case any of those firmwares boots up but you face any problems or you just want to use the k220ar firmware (since thats more up to date) you can make a "hybrid" firmware:

1. flash the firmware you want to use for good (k220ar)

2. get into TWRP and allow system modifications - then reboot (you will get the device corrupt message but it will boot up)

3. get into TWRP make a backup of your "boot", "system" and "system image"

4. flash the last firmware which was rootable (any firmwares before february 2017).

5. get into TWRP, swipe to allow system modifications, reboot

6. get into TWRP restore those partitions listed above then in TWRP's "reboot" menu chose "power off" and make a hard reset (http://www.hardreset.info/devices/lg/lg-x-power/).

(Here is my detailed guide for the k8: https://xdaforums.com/showpost.php?p=72414225&postcount=250 )

If your phone boots up after these steps then you can go for a root.

Keep in mind that each of these firmwares requires ported twrp for that particular firmware:

https://xdaforums.com/lg-k10/development/mtk-portable-twrp-porter-t3536123

and that most likely you will need to make some changes in the lg up's reg file and add it to registry after each firmware is flashed in order to use lg up again - you will understand this part once you looked into my lg up thread.

Don't forget the oem unlock options before getting into twrp after any firmware is flashed (the bootloader stays unlocked but i think in the developer options you need to tick it every time).

Before you proceed look into the firmwares via lg firmware extractor to see if there is no significant difference from your stock firmware to avoid hard bricks. Still i can not take any responsibility if the process causes you any hardbricks!

Help me I have the lg k8 2017 (x240F)

I want to rootearlo but I do not find anything, I was wondering if anyone knows anything about this new model because the truth is full of bloatware and I would like to roote it. Thanks!
[LG K10 Guides, News, & Discussion] losoollenos:
How about gottlasz all right ??

I wanted to tell you that the method actually allows root access on my phone (k220ar), as you said with a kdz before February 2017. I followed all your guides and managed to run the lgup, porting twrp with your script and finally rooting the mobile.

The problem is that when the RCE-SuperSu-RCE process is finished, the phone starts up perfectly, the root apps work and everything is normal (what a joy !!!), but when I reboot my phone it does not start anymore, I've tried a couple of Times and the same thing happened to me. In the last test I took the precaution of not modifying any system files (which I had done before) but also at the start it shows the message "your device is corrupt ......" and then it just goes out.

Hopefully you can have a solution friend, here I am to prove what you ask me !!!

Thank you very much ;)
[LG K10 Guides, News, & Discussion] gottlasz:
Well... this is an interesting problem.

We can try a few things to sort out the problem.

1. when you are on a clear firmware get into twrp swipe to allow modifications -> reboot -> this will get you the device corrupt message but the phone will boot up and system modifications will be allowed. Get into twrp again and delete one or more system app ( https://xdaforums.com/lg-k10/themes/stock-google-apps-delete-root-t3518613 ). Lets see if it boots up and what happens when you reboot. (i think you need to have twrp 3.0.1 or above to be able to see the system folder in twrp)

2. When you are on a clean firmware do the root process whitout installing supersu (only install rce twice) and test phone rebooting a few times.

If these two tests are passed (so phone works without a problem in both cases) maybe the problem is supersu related so you should test with a different version. Or maybe you have to turn off automatic updates for supersu in playstore.

There is also one explanation like what if the boot image is returning back to stock after the second reboot (i never heard such thing before but who knows). I know that there are some devices in which the custom recovery is not sticking but returns to stock after a reboot. This leads us to a third test:

3. After you are done installing rce - supersu -rce before you reboot make a backup of your boot image in twrp. Then after you booted up and root works go back to twrp and make a backup of your boot image again then compare these boot images with carliv image kitchen (unpack them and compare each files see if there is any difference).

You can even look up how systemless supersu works (how its triggered at every boot up and which partition its using not to be deleted after reboot). Maybe your phone is deleting the supersu.img after reboot. (As much as i understand when you install supersu systemlessly it makes a supersu image somewhere - like onto the cache or data partition - and the boot image is modified to load supersu every time the phone boots from that image. Maybe that image gets deleted after the first boot up and thats why you cant boot up again - could be some automatic cache erease at every reboot. But i have to say i regularly empty the cache and i have no problem with reboots so its probably something else).

Do some tests and let me know the results!

I have problem. I have data free 669mb, forum one hour my phone eject that I no have memory data!, cache memory clear, rooted phone, I have instalacije five applications near system applications.

What I do, where and what I look on internal memory that not full. I dont touch anything.

Gottlasz what I do?
[LG K10 Guides, News, & Discussion] gottlasz:
Unforunately our device behaives exactly the way you describe. Even if it sais there is some hundred megabytes free there is not. It's holding it up for something.

Usually in those cases i clear cache at options/storage/internal storage and just click on cache.

There is nothing else you can do. (Maybe delete some pictures/videos/music from internal storage)

Also i use the app FolderMount ( https://play.google.com/store/apps/details?id=com.devasque.fmount ) - if you are rooted it helps you put some apps data onto sd card/external storage.

[LG K10 Guides, News, & Discussion] losoollenos:
What about my partner, I'll tell you. In the first test that you suggested I had no problems, I had already done that even when I was with kdz after February, I eliminated as many apk as I wanted and I had no problem (although it was not so when trying to insert a MOD by twrp, I wanted to change the hosts file and the mobile did not start any more).

In the second test there was not the same fate, after the rce-rce ...... the same thing, started well for the first time but when I rebooted, it only came to the message "corrupt system ..." and it went out, I tried a More than twice but with the same result.

Maybe this error is better than if it had more relationship with Supersu no ??, can you solve it ?? A greeting, I hope so!
[LG K10 Guides, News, & Discussion] gottlasz:
I'm afraid it is gonna be the little kernel (bootloader) is checking the boot image even on earlier firmwares not like our k8/k10 (since when you boot from twrp it migth skip the little kernel part during boot up).

Maybe give a try to do the second test again and when you booted up don't reboot normally but go to twrp and reboot from there (you can even test what if you make a backup of your boot image before the tweaks and restore after the first boot up - this would give you a one time root so you can do some tweaks).

I can think of one more thing to try:

https://xdaforums.com/android/software-hacking/signing-boot-images-android-verified-t3600606

download the zip version and install it after installing rce twice.

You can also take a look at my old thread:

https://xdaforums.com/lg-k10/how-to/twrp-root-lg-k8-k350n-t3475807

Rce-zip-rce or rce-rce-zip ?? Excuse me but the translator is not clear to me

How is complicating android ..... at any time I recycle my LG G2 and in the future we will have to go looking at iphone if this is still closed like this
[LG K10 Guides, News, & Discussion] gottlasz:
rce-rce-zip.

Just a little explanation:

rce - changes the ramdisk compression to gzip - required by supersu

rce - changes the ramdisk compression back to lz4 - required by lg system

verified boot signer (by Chainfire) - signing the boot image because signature gets lost during the compression exchanges

please read them threads carefully so you understand what you're doing. ;)
[LG K10 Guides, News, & Discussion] losoollenos:
But if I'm not getting supersu, why the rce-rce?
[LG K10 Guides, News, & Discussion] gottlasz:
Just to test what happens if you tweak the boot image. Then when you can make it work supersu will work too.
[LG K10 Guides, News, & Discussion] oblyvision:
Maybe the purpose is to know if changing ramdisk compression once might affect something during the second booting, which I doubt so.

Btw which version of SuperSU did you flashed? I still recommend 2.79 (afaik the only working SuperSU for K350K, probably for others too)
[LG K10 Guides, News, & Discussion] losoollenos:
Nor did it work ..... rce-rce-zip and again first correct boot then reboot-message corrupt-off system.

Luckily reinstalled with lgup checking "update" and everything is fine as it was. I'll try the 2.79 total .....

We have some alternative gentlemen ???, in any case many thanks for having tried as much as I, giving me tools and information. thanks again

PS: Since we are also tried with supersu 2.79 but in this case did not start nor the first time ....

regards
[LG K10 Guides, News, & Discussion] gottlasz:
No more alternatives i'm afraid. The little kernel (bootloader) should be tweaked but it can easily create hard brick so i don't suggest modifing it.

for anyone who can't root their devices, please read carefully on 1st post , especially about making

"DEVICE CORRUPTED"

- after boot into twrp hit cancel decrypt then swipe allow modification THEN REBOOT SYSTEM

- when boot your phone booting, you

MUST SEE

remember you

MUST SEE

"DEVICE CORRUPTED"

IF NOT GO BACK UNTIL YOU SEE THAT notice, IF YES >>

- go back into adb command again, fastboot into twrp again then ready to install rce_univ.zip and SU , make sure to use

SU ver 2.79

, then install rce_univ.zip again

then you can safe reboot system, just wait be patient dont unplug anything.

if something happened to your phone , please read this thread https://xdaforums.com/lg-k10/how-to/flashing-firmware-using-lg-t3517839 , also you can use for downgrading your phone ( security patch into 2016 )

download your KDZ : via my guide or https://xdaforums.com/lg-k10/development/stock-versions-model-lg-k10-t3457319

I can simply say this; I had rooted it in the same thought you think. It was just forever for me. But it wasn't like I thought.

Hey,

First reboot into bootloader (fastboot): adb reboot bootloader

then check if oem is unlocked: fastboot getvar all

somewhere in the last few lines you will find if you're unlocked.

Then boot into recovery: fastboot boot twrp.img
