[Q] Help Needed for LG LTE LU6200

Hi All,
I got LG LTE LU6200 as gift from my aunt. But it is loaded with tons of Korean apps, which I don't need. I am also unable to uninstall them.
Currently my phone has Android Version 4.0.4 and Software Version LU620167.
I couldn't find any complete help for rooting and installing custom ROM in this phone. Can someone help me in this regard? (considering me as a newbie)
I will be very thankful for any help or response.

So your'e saying that none of the threads in the LU6200 forum tell you how to root and/or install custom ROMs? There's a few threads on the 1st page about rooting, unbricking, and installing CWM on the LU6200.

If it's in download mode, can you resume the guide from where you place it into download mode? Have you attempted to perform a factory reset (press and hold volume down and the power button until the factory reset screen comes on)
If none of that works, there looks to be a couple other guides there; best bet would be to try them. If all else fails and you need your phone to at the very least, work as a phone, you might can try to update your phone to stock using the LG update software.

Yes, I performed a hard reset, and after that, LG logo appears and then again I am back to download mode screen
Can you please give me a link for other guides as this forum is flooded with topics and I couldn't judge which procedure should I follow?

Once rooted, you can use Root Explorer to remove native Korean apps (AhnLab, LG counsellor, Tservice etc.)

Can anybody please tell me if this phone is USB-OTG (USB Host) enabled?

Try to search again in the LU6200 development area for your question, if you are not able to find the solution in there you will have to translate vietnamense and chinese LU6200 sites with google translator

LG730 - Venice - Downgrading firmware to ZV5 from ZV8 so i can root it

hey all, just got my 1st smartphone here. the LG Venice.
i love it , but always wanted to root it. that was the main point in getting it.
so i went and got this the other day, and unfortunately the guy at the store
went and upgraded it for me from the good version to this new UN-rootable version.
at the time i didn't know this, or i woulda stopped him.
soooo, I've been reading all over and the consensus is to downgrade it to zv5,
then root it, then save the root, then upgrade back to zv8, then restore the root.
ok, no prob, but i cant get the zv5 firmware to take. i;'ve found only 1 place that has a link to a .cab file. and it don't work.
others have had this same problem, but i cant get ahold of anyone....
if i flash 5 on it, it gets stuck at the boost logo screen. only way to fix is to flash 8 back on it.
so if anyone has an idea or a good zv5 image, or a link or something! or a way to root it as is.. please help!!!
thanx

[Q] Downgrade from android L on LG G3

Hey guys massive noob here, wondering if it is possible to downgrade from android l to kitkat or to root android L on the G3. I foolishly updated and my root is gone, stump is not working (obviously not made for L yet) and I can't find any help elsewhere.
I need to root my phone and I don't care whether the the best way is to downgrade or to root if it is available for the new os. I will lose my data other than what is backed up via dropbox etc but it's not a big deal for me.
Help much appreciated thanks

Yes it is possible just downgrade to Kitkat using the lg flash tool then root using Purpledrake
You can get the KDZ file required from this link : http://forum.xda-developers.com/showthread.php?t=2791761 (make sure you select the correct file)

Root: http://forum.xda-developers.com/lg-g3/development/root-root-lg-g3-easily-purpledrake-lite-t2821000

Yup, what he said it's fairly easy. Give it try, let us know if you need help.

I've fallen at the first hurdle, which firmware do I need?
I have a UK vodafone LG G3, 16GB, LG-D855, and I want the last version of kit kat available. I'm more than a noob.. .
Also why do you choose Purpledrake over stump, is there any difference?
Thank you so much

This firmware you want is A6VF, it is near the bottom of the list.
The reason I use purpledrake over stump is because some times it won't root and says "...Not supported" but feel free to try stump if you want and if it doesn't work just use purpledrake.

Hi. I got trapped with unrooting and updating to lollipop lg g3 D85520e-EUR-XX and wanted to return to kit kat 4.4.2. It's the 32 Gb model. Can you help with the KDZ i must download (I can't understand the four first characters of the list!). Thanks!

What network are you currently using? or is it an unlocked phone. A country name would also be helpful as that's how the files are organized.

It's unlocked. It's in Spain. Lg g3 D85520e. 32 Gb model. It came with kit kat 4.4.2 and i aplied PurpleDrake succesfully. Then I unrooted to upgrade to Lollipop 5. Ver. 20e. And now, I can't root anymore. So I would like to downgrade to Kit Kat 4.4.2 to be able to root again with PurpleDrake to recover my root privileges, especially to manage apps and their writing to the external sd card.
Thanks very much for your help!

To get the exact suffix required use this website
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
Replace IMEI with your imei then press enter. Then post your suffix

It looks like if it were the same KDZ already installed... : FW9BRPVE022NAX045560S86/D85520E_00.kdz ??? What I need is the Kit Kat version 4.4.2 10x(a,b,c,...) to downgrade from this one (20e) and be able to root again the phone. I probably have explained myself wrong. Any idea?
And thanks for your efforts, by the way!

If he does a CSE flash he won't need to? Just making sure.

That's it! I'm going to download! Thanks very much. Everything is possible with people like you!

I'm glad we could help Keep me updated on your progress in case you have any problems.

I totally messed everything up (stuck with brick)

I am an idiot..
Long story short my LG-D852 RGS is showing as an LG-D857 in LG FlashTool and I am unable to flash the correct rom as I keep getting an error message:
"Download fail!! Device model is different"
I somehow flashed my D852 to a D857 while messing around, and now I can not find any way to recover to factory.
Anyone have any solutions that can rescue me from this bricked phone?! PLEASE

If you want some good help to recover your phone go to this thread and ask for help or ask even if it is possible since you flashed the wrong ROM.

Only way you can fix it is probably kick it into Qualcomm USB Loader 9008 mode

Yes I actually agree with that.
Here is the link to that thread which is actually closed but the OP of this thread here can have a good read and perhaps Google for the software to download.

I actually fixed it using a modified .DLL file that bypassed the model mismatch so I used it with the stock bell 5.0.1 and LG flash tool and it finally worked

Very glad you got it sorted. Another success story!

I am confident this phone is basically unbrickable, much like other LG devices I've had in the past

Hey,
Your question doesn't seem to be correct. You need to explain a little more about it. Before i can help you i want to ask these questions.
1: Have you rooted your device. 2: Have you flashed twrp recovery. 3: If you are running a stock marshmallow rom then how you installed it by LG Tool or KDZ method. 4: How are you trying to open this recovery (By key combination or some type of software)
I know these are strange questions but i can help you better in this way.

I suggest you do a lot of reading and when you think you understand it all read again because if you don't you may make your phone unusable.I give you this warning because obviously with the answers you have given you lack the basic knowledge of rooting and installing a custom recovery.
I recommend you read these links and then read them again until you are 100% sure you know what you are doing >> http://forum.xda-developers.com/lg-g3/general/lg-g3-sticky-roll-thread-t3123907 << if you have questions on any of the links just post the qustion in the relevant thread for the link given. I'm not trying to put you off just trying to make sure you understand everything so that you don't make your device unusable.
Good luck and do plenty of reading first..
