[Q] Why can't I root my L5?

Hi, I seem to have a few problems rooting my Lg optimus L5. I am on android version 4.1.2
I have tried the Framaroot method, as suggested in this tread. The app opens and I select the Gandalf exploit, as suggested by the maker of this app, but after I select my exploit, the app just closes.
I have also tried the method on this tread but after I open root.bat, it runs a few lines, says there are errors with a few ones and closes itself. I have tried this method 2 or 3 times
I think I tried another method, but I can't seem to find it, I'll post here if I eventually do find it.
Edit: I found the other method(all I had to do was look at my desktop, there was still a folder with the name of the method there... silly me!)
The other method is Super One Click, and that didn't work either...
Also, can someone explain to me what does V20D mean? Is it a rom, a kernel version?
P.S.: Please forgive me for beeing such a noob, but I really did search through the forums (maybe not well enough...) and didnt find any method that works

Sadly, there is only 1 method available to get lg l5 4.1.2 rooted.
Install a pre-rooted firmware (and, that's what v20a or b or d is) using kdz.

Thank you for the answer, could you link me to a guide? Also, will this"wipe" all my apps and their data?

4.1.2 pre-rooted. Flash any one using kdz updater.

1. Install supersu.
2. Install ROM manager, select e610 as your device and flash cwm (or twrp) recovery.
Here's a guide to do the same. (use the rom from the first link, since the link to the rom is broken in the second link)
http://forum.xda-developers.com/showthread.php?t=2230679
IMPORTANT : If your phone is e612, download the recovery.img (for clockworkmod) of e610 only. Otherwise, you will get bootloops.
Yes, it will delete all your applications and data. It will delete all the contents of your internal sd card.

God dammit, my phone wont enter emergency mode!
Thanks, my phone is now rooted! Funny fact: My data was not wiped, I still have all my apps, and I have checked with root checker if I have root , and I have, so thank you :good:

Wut?
Using kdz update tool, wipes all data...
How did yours not get wiped?
I guess, flashing a v20 on another v20 doesn't wipe the phone

[Q] The phone stuck at the LG loop, bricked, help needed!!

Australian unblocked version, said D802T I think. 4.4.2 official kitkat upgraded.
I rooted the system this afternoon using Ioroot25, and it seems like succeeded, coz I saw the supersu icon.
Then I installed the Autorac.app, which said to be working on all models, but later the admin told me not fitted for this D802T, I got really confused honestly. What's the difference between this D802T and international D802? Even installing firmware haven't seen any Australian version, for gods sake!
Anyway, I could get access to TWRP interface, and could go to download mode.
How should I bring the system back?
And plus, or maybe later, how to install TWRP on my G2? Just need that bloody 4K/120fps camera rom...
Really appreciate your help!!!

Download some aussie rom(not aware if there are any?)
then adb sideload rom.zip (enable ADB option in twrp).

Wait..you can go to dload mode ?

if you have TWRP installed then you can flash modified MM stock or custom rom (zip file)
or you can update to MM stock with kdz file and use kingroot for temporally root if needed

There is permanent root for MM but there is one problem, modem from stock MM will be replaced with old modem version v21a\c when you permanently root. Dont ask why its just the only way right now.
And a lot of people having problem with sim wifi bluetuth gps after that.
Any stock marshmallow modem can't be used on a rooted device, so you have to make a choice, either you want root and twrp and probably problems with sim wifi bluetuth gps, or stock modem that works always good and root when needed with kingroot. I choose the last option for myself.

Cannot downgrade from MM to LP
I bought a second hand LG G3 Cat. 6 (F460S) which is currently on MM.
Then I decided to go back to LP by flashing F460S20C_00.kdz file using LG Flash Tool 2014 method. (Download mode)
I went back to Lollipop, but then decided to be on Marshmallow with the use of LG PC Suite/ LG Mobile Support Tool.
But after some time I realized marshmallow drains battery faster that is why I want to go back to Lollipop again. But when I use the LG Flash Tool 2014 method (which I have done successfully for 2 times before), I cannot go back to Marshmallow.
Please help
I have done the connect cp, open LGUP, then restart cp. but still LGUP says unknown device

I can make it even easier... instead of downloading my 10E COMPLETE ZIP
Just download/flash my 10E BOOTLOADER ZIP. It'll make LGUP work again with M KDZs and the BOOTLOADER ZIP is much smaller!

I had several problems with this procedure (coming from V20a):
1. After flashing 10C BOOTLOADER ZIP via TWRP, LGUP was not able to detect my device type anymore, but this worked with previous bootloader. Why?
2. Flashing the 10C COMPLETE ZIP did result in a loss of TWRP (although recovery.img is not part if complete ZIP). Why?
3. Flashing the 10E COMPLETE ZIP caused FCs and a bootloop Reset in system recovery did help to get the device up again.
After that LGUP did find again my H850 and upgrade option works now with M KDZs (which did not work under Nougat). But the refurbish option is still not working and says "not supported".

1. I suggested 10E not 10C.. not sure why LGUP 1.14 + UPPERCUT wouldn't see it. But UPPERCUT is geared towards recent devices on recent software. It's possible 10C is too old to fall under the UPPERCUT 1.0.0.0 umbrella.. and you're always welcome to use the older LGUP methods instead.
2. You will always lose TWRP if you boot into Android without patching the boot.img or flashing supersu zip first. The stock system.img has a patch in it which always tries to replace the recovery partition with stock recovery.. and zips like supersu stop such things from happening. The procedure is to flash twrp.. boot into twrp.. flash supersu. flashing twrp then booting into android = no more twrp. this is standard android stuff for awhile now.
3. The refurbish option isn't needed and I've already explained in the UPPERCUT thread that refurbish is not supported. All refurbish option does is force the phone to run a factory reset after KDZ finishes... the user can just run a factory reset manually after the flash to achieve the exact same end result.

At first: Big thanks for your quick response!!!
to 1.: The reason for 10C instead of 10E is simple: you do not have a KDZ file for 10E on your codefire drive (only a ZIP), but for 10C the KDZ was available. And the links to LG server were not working yesterday for me.
I read Uppercut the first time now and will give it a try today in the evening (German time). :fingers-crossed:
to 2.: Understood. Thank you! :good:
to 3.: Then how can I get rid of the 3 error messages on start-up related to NT-code ("Can't find matched cust for NT-code" + "OP name for Buyer-code...")? I understood, that refurbish will flash new cust partition and this will solve the problem. I see cust.img also on your drive, but it is not inluded in the COMPLETE ZIPs. Would it help to flash this?
Or can LG Bridge help in this case? It does refuse to flash my phone, maybe because of the bootloader unlock?!
I read so many threads yesterday, but nothing solved this issue... :crying::crying:

cust should be getting flashed regardless of selecting refurbish or not as far as I know.. but perhaps I'm wrong.
if you have root/twrp just zero out the cust partition or simply delete the files inside the cust folder using a file explorer app... and the error msg should go away on next reboot.
this is in the FAQ/Q&A section in the OP of all my stock threads for H850.
if you're on M and must flash a KDZ with refurb option... just use the old LGUP methods. but if you're sticking with TWRP there's not really any need to flash any KDZ.. you can flash whatever in TWRP instead.

"and the error msg should go away on next reboot." I get 3 error messages related to this. Will I get rid of all of them?
"old LGUP methods" means tool version 1.11 instead of 1.14? So use version 1.11 for MM and 1.14 for N?!
Unfortunately, refurbish does not work even under MM for me regardless if I use version 1.11 or 1.14.
BTW: The old version 1.11 asks my each time I trigger the refurbish process to "Input new NT code" (the new version does not behave like this). Is my problem maybe caused by this or can this be used to input a working string there?

i dont have an H850 so idk.. but any time ive had someone zero cust theyve said errors have gone away. so if they dont for you.. you must be special. try it and find out... then report back. if it doesnt work... ¯\_(ツ)_/¯
old lgup methods = 1.11 + dll msi installer, yes. but i see no reason to use 1.11 simply for refurbish option. most people should be able to use LGUP 1.14 + UPPERCUT for most situations on G4/G5/V20.
i dont know abotu the NT code stuff with LGUP.. again.. I dont have a H850. but if you have TWRP then there's really no need to be messing with LGUP at all unless you want to be 100% stock/unrooted with no TWRP. just zero cust or try flashing the cust.img that's in the folder.
I cant help any more on this NTCode subject without a device that uses it. good luck.

@autoprime Can't we just flash 10E with the refubrish option? Somehow I'm unable to get into recovery with the button combination after downgrading and updating again, even though I'm doing it properly and I was able to do it before.
EDIT: So refubrish stopped working now too. Dang. I installed the recovery through Dirty Cow, flashed the bootstack and went back to 10E, but I still don't have a recovery. ;_;
Ok, I've tried everything and button combination for recovery still doesn't work, so think if you really wanna risk being unable to easily factory reset your phone.

Well I am trying to flash stock EE rom, which I have the KDZ for.
I am flashing via upgrade, and all that happens is when the phone boots it is unstable, phone app crashing etc.
All settings still intact, no myee app, app from open EU rom still exists, very very strange.
Is it possible to convert a KDZ to a twrp flashable zip as twrp seems far easier.
I suspect if I used refurbish it would fix this issue as upgrade seems to not be clearing everything.

Did u try what I suggested in other thread? Wipe internal storage before first boot, reboot recovery afterwards before booting system; are u clean flashing? Are you trying to restore any data at all besides things like messages and call logs?
Going from an openEU.kdz to a branded .Kdz would definitely require a Twrp data format and a recovery reboot, perhaps do all this b4 using LGUP with kdz.
Yes it is possible to make a .zip from a kdz, but it's not a simple process and there is no EE branded 20a.zip
Autoprime already stated that refurbish option can be used if you use LGUP v1.11 instead of latest 1.14 but don't forget the .DLL file. Also all refurbish does is wipe data and internal storage; which can be done via TWRP using the method I mentioned above. Try what I mentioned and then reflash kdz;forget about any data besides text messages just take the extra 30min to resetup device from scratch.
What version of LGUP are you using? Can u give more info be more descriptive about what's happening?

it is resolved now but I was just trying to get it in a good state to return the phone to EE.
Doing a factory reset in twrp didnt work, but what did work is I did a reset from in the rom, and after the reboot it was properly reset.
What was odd is when I wiped system and data manually in twrp that also didnt work.
I think I forgot to check if I completely wiped the internal storage, photos etc. As I was rushing to get the phone to be sent back. But the description for the reset option in android says it does wipe all personal data so hopefully that did it.

How can I downgrade LS992?

İs this possible for lg g5 H860?

For H850 just download H85010i_00_OPEN_EU_OP_0923.kdz flash it with LGUP 1.4(uppercut) after it's finished reset the phone then just flash android 6 firmware that you like.

i have h850 ,
current firmware is v20a updated via fota
no root , no bootloader unlock ,,, compleatlly stock phone
i want to downgreade to any 6.0.1 firmware without losing data (if possible)
if not, what to check and what steps to do without tripping on cust ot drk or modem or .... issues ?
pleas advice me ....

LGUP corrupts whenever i hit Start, but it works just fine with N kdz (mine is 20a). I have tried to flash bootloader but still ended up with the same outcome.

I rooted H850 following autoprime's LG G5 H850 Bootloader Unlock instruction with autoprime's modded "Minimal ADB and Fastboot" {[ 1.) selecting port 41 in device manager (maybe was not necessary) and 2.) pushing TWRP twrp-3.1.1-0-h850.img 3.)booted into recovery (Using 2 hands.. use one hand/finger to press/hold volume down.. and use the other hand for the power button. Press n hold both buttons.) 4. flashing SuperSU (UPDATE-SuperSU-v2.82-20170528234214.zip) ]}.
Installed 20a with lgup because for a strange (windows 10 folder administrator permission) reason nether UPPERCUT_1.0.0.0.exe nether LGFlashTool.exe worked properly).
Unfortunatly I installed [ROM] [Nougat 7.0] Fulmics ROM 3.3 ◦ v20D ◦ H850 but, because the very big LACK of xposed framework on nougat, I had too much difficulties to patch correctly the core jar with lucky patcher getting a lot of error "app not installed the package appears to be corrupt" and other play store error 504 app not installed.
So I decided to downgrade and leave from any Nougat 7.0 based rom in order to move on Marshmallow 6.0. In particular I used TWRP to wipe everything and flash [STOCK][M] H850 10E OPEN EU ROM autoprime's 10E COMPLETE ZIP then Supersu then framework.
On android this time I skipped google registration and LG software updates with data and wifi OFF.
Then I activated USB debug in developer section
Then I followed these step in that really precise order:
a) installed super su again with twrp (want to be sure to have got ROOT);
b) configure Super Su setting in android to activate pseudo PRO option then uncheck the "separation mount space" in order to share .init;
c) configure Super Su setting giving permission always without asking and also during in boot (to everybody);
d) installed xposed-v87-sdk23-arm64.zip in TWRP
e) installed lucky patcher and using it to unistall every LG apps;
f) activate for the very first time wify in order to update immidiately lucky patcher (update available in lucky patcher settings) than download patch update;
g) installed xposed apk (in android obviosly because I refer to apk pattern) and run it following app procedure for a correct detection of framework then activate Lucky patcher module in xposed apk then reboot to permit lucky patcher using framework;
h) installed busybox (after the check I choose the "smart install").
i) and now I enjoy the freedom that I haven't got in Nougat to test some application before buying them, just to be sure to not waste money for fake apk like voice pro or other expensive one that fools me before so many times. :good:
Update: G5 H850 Genisys Theme 1.3 v10e MM is a great choice for stability and battery life.

Before flashing it to another variant G4, you must take upon oneself the consequences

LG Taiwan H815 v20E KDZ
Installation:
We need to downgrade 6.0 to 5.1 before flash Nougat
1. Check Anti-rollback version in *#546368#*815# -> SVC Menu -> Version Info (Important!!!)
If the value is 0, fine, goto step 2
If the value is v1, v2, v3 or above, DON'T USE THIS GUIDE OR BRICK YOUR PHONE
2. Install LGUP and Driver, shutdown your phone, goto Download mode by press Vol-UP, connect to your pc
You should see Firmware Update shows up on your screen
3. Open LGUP, select REFURBISH, and choose BIN file "H81510F_00_0113.kdz", press Start button
Code:
On the LGUP you first need to select :
1. UPGRADE
2. Choose the .kdz file
3. Go back to REFURBISH
4. Start ( Begin the flashing of the device ).
( thanks @lekk for these missing guide :) )
4. When rebooted, do a simple set, and go to Setting -> Backup & reset -> Factory data reset
Reboot again, do a simple set, copy rootsystem20160214.img & eu.chainfire.flash.v6.apk & LG-H815_Official_v29A.zip to internal storage
5. Shutdown and goto Download mode again, open LG ADB pack, double ports.bat , you should see\Device\XXXXDIAG1 REG_SZ COM#
The # is a random number, remember it, we'll use that at next step
6. Open cmd and change to same folder, type
Code:
Send_Command.exe \\.\COM#
"#" is the number what we just seen in ports.bat
You should see Enter, Leave and a #, copy
Code:
dd if=/data/media/0/rootsystem20160214.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
then press enter
Wait a while, another # will appear, pull out battert and reboot
We finally downgrade to 5.1 with root, and now we gonna flash Nougat
7. Now you should see SuperSU in your app drawer, install eu.chainfire.flash.v6.apk, then open FlashFire
8. In FlashFire, click "+", click Flash ZIP or OTA, choose LG-H815_Official_v29A.zip, and don't tick anything, go next step
9. Scroll to the bottom, click FLASH, click OK, wait till the phone reboot to FlashFire mode
10. When the phone reboot again, you should now see Android is Upgrading
11. Goto Setting -> Backup & reset -> Factory data reset, do a full factory reset
12. Wait the phone earse and reboot itself
13. Open LG Backup, mount your SD Card, select Restore, and enjoy your new nougat 7.0

Before asking any question, be sure you have already checked this Q&A list!
Known Issues:
Q1. I'm stuck at LG Logo after flash 5.1 KDZ
A: Pull out battery and enter recovery mode to do factory reset
Q2. Will my G4 overheat or dead while flashing?
A: All G4 still alive now won't dead, while flashing, they mutation
Q3. Should I upgrade to Nougat? Is there any feature better than Marshmallow?
A: Google "Nougat vs Marshmallow"
Q4. I'm now at 6.0 and Anti-rollback version is 0, do I need to downgrade before flashing Nougat?
A: Go to the top and read this topic again, GO
You can't unlock bootloader that mean you can't dump out system.img to do root injection
And you can't use TWRP cuz you have a locked-bootloader
So, we need to downgrade, using the 5.1 Download mode to flash our modified system.img
Gain the root permission and use FlashFire to flash that firmware
This method looks like HTC's Bootloader firmware flash, but we use FlashFire to do this
Q5. Will Nougat cause G4 overheat or battery drain?
A: No, but smooth and stable, surfing web just a little warm
But I don't play games, so you need to try this urself
Q6. Hey! Is there any root injection in this Nougat firmware?
A: No, this is an official firmware signed by LG, un-touched, so ... sad
Q7. Can I do a root injection to this nougat system.img?
A: No, you can't, go back to Q4
If you modified the system.img and flash it
You'll get a fully bricked phone
Q8. Why I should do factory reset again after nougat boot up?
A: FlashFire flash that firmware just like when you receive an OTA and flash it
That a dirty flash, will cause lag, overheat, or other issues.
Q9. Can LG Backup restore all my data?
A: Some applications can't backup their own data,
but I know Steam Guard can!
Cuz I just logged in my Steam through that restored Steam app!
Q10. Can I roll back to Marshmallow or lower version?
A: Yes, you can!
But wait, check Anti-rollback version, if the value is 0,
then use LGUP, "REFURBISH" your phone to European v10 KDZ
Check anti-rollback version still "0"
After flashed European v10 KDZ, REFURBISH your phone again to any country/version's KDZ
Q11. Hey! Why my rootsystem20160214 not a img file, it's a 7z format file!
A: Don't you know that a zipped format? Go search it.
Q12. OMG! My phone stucked at LG Logo with breathing light
A: It's still boooooting, don't take out battery or anything else, let it boot up.
Q13. My phone realllly stucked at LG Logo, and LGUP show Unknown Model or Unknown Port!
A: Try LG Flash Tool, flash TWN v10F KDZ or other country KDZ.
If your LGUP or LG Flash Tool can't recognize your G4, and you surely the driver correctly installed...
The reason is: Windows 10 with USB3.0 port won't work, try Windows 10 with USB2.0.
Quickest way: Why not use Windows 7?
Q14. Can I get Android Pay working if I upgraded to Nougat?
A: You can't. Some "root" files still in the system partition (I don't know where are those files stored).
So your phone can't access SafetyNet now.
Q15. Is there any way to get my Android Pay work again?
A: Try REFURBISH your phone to a European KDZ
Then REFURBISH to any country/version KDZ, that's would get your Android Pay work again.
Oh.. I didn't try this but I think it would work, cuz I don't use Android Pay
Q16. So, why can't we access SafetyNet?
A: Some "root files" can't removed from the system partitions, if Google Play services detected those files, may cause "CTS Profile match: Fail"
Q17. Everything worked fine after this upgrade, but it shows "Current Version is not available for user. Can't find cust for NTCODE=[XXXXX,FF}", how to solve this?
A: It's normal cuz the firmware doesn't match to your phone's region / country, dismiss that, and enjoy your nougat
Q18. I can't get 4G+ on my G4, why?
A: This firmware's baseband doesn't match to your country's band, not a major issue.
If you really care about this, downgrade to Marshmallow

See attach

The method is working fine for international H815. Freshly updated

Thank you bro!!!

Kinda sad that it voids your warranty tho.
That is legit the only thing that makes the fact we cant unlock our bootloader a good thing- whoever has a warranty keeps it.

at least here in Israel, all G4s are sold with a 2 year warranty.
Honestly if it didn't have the warranty I'd use this, but I do want to keep my warranty. It's kinda odd how this does void your warranty, and another bootloader locked rom that i know doesn't void your warranty. I assume it has to do with the fact that the method of flashing this rom does require root.

Hey, thanks for the guide.. Will give it a try immediately. Was waiting for this for a long time.
Can we use this method to flash LineageOS Nougat or Oreo as well or does it only work with stock LG firmware?

This is a fully stock ROM, downgrade to 5.1 no need to unlock the bootloader, we are using the bootloader's bug to flash modified system.img, and then, upgrade to nougat, a fully stock Nougat ROM, you can't root, and the bootloader still locked.
But I don't know what if we flash this, the phone still in warranty or not.
And here, in Taiwan, Taiwan LG is selling LG G6 now, they don't sell G4, our warranty only 1 yr.

This method only works with stock ROM, if you try to flash a third-party ROM, you'll stuck at LG Logo cuz the bootloader don't know what the fxxk is this system, See "Known Issues" Q7

After updating to the V29a lift LG backup stop working notifications restore 2 times the two failed, I had to perform wipe and returned to normal.
Do we have root to delete apps that I do not use LG?

The com port was the one you need.

Or a screenshot

Don't do that if you don't have any confidence
But you can try this guide if you find a 5.1 version KDZ for your H815TR.
If you bricked your phone, try to flash back to stock KDZ
Good luck!
