[TUT] Downgrade and Conversion F350L/S/K to D838 using KDZ

For F350L/S/K:
On a stock android 5.0 lollipop you must be rooted first.
download the one click root script by Unjustified dev http://www.droidviews.com/easily-root-lg-devices-using-the-one-click-root-script/
credits goes all to him.
After root.
download buildprop editor.
edit ro.product.model change to LG-D838
Download any D838 KDZ here http://lg-phone-firmware.com/firmware-LG+G+Pro+2-Tutti-62.html
Using LG Flash Tool 2014 download here for tutorial and LG USB driver http://forum.xda-developers.com/showthread.php?t=2797190
navigate your downloaded KDZ of your choice and click CSE Flash leave everything untouched
note: CSE Flashing will factory reset the phone and internal storage will be erased so back all your files on PC or SD
credit all goes to the author/dev and for their greatness

Thanks.

Any confirmation??? it would be awesome if it works

Would be ery happy to know. I dont want to brick my device

It works! My device was f350l and now is d838 with lollipop rom of d838，clean of all korean apps. I followed the tutorial，edit build prop and flash kdz of d838. All perfect!! Thanks a lot

Think you this will work with an Lg G2 F320 S to G2 D802?
F320 S had Micro SD Slot and D802 have not.

I dont know，im sorry. I made the tutorial afraid and step by step because i didnt like the korean apps and because lollipop on f350 was a sh... In your case. But i can supose that this dont serve to you because of the micro sd

Ok Thanks for the Answer.
But flash the D838 KDZ Modem,Cust,Recovery,etc.on your F350 and this works?

First i edited model with build prop editor. Then i only flashed a kdz with flash tools
Enviado desde mi LG-D838 mediante Tapatalk

Not working for me, any ideas?
I have F350L (Korea U+), i done a clean F350L CSE KDZ flash first, then only rooted it and changed model to LG-D838, now when i try flashing 2 different D838 32GB KDZ's it fails at 3% on the pc (the phone shows no progress)
I can easily flash it back to F350L.KDZ so i know my driver & flash tool 2014 is working ok..

we need to downgrade to kitkat first? it didnt work for me also. I have the Korea L version

Thats what im gonna try tomorrow

Still no luck for me, i downloaded Kitkat TOT & DLL files for my F350L loaded that fine, so now on stock Kitkat, i just rooted it and changed model to LG-D838, same result as before, someone who has successfully done this conversion please help!

Can i do this on my g pro 2 f350l on 4.4.2. Is there any video for help?

I think its more of the bootloader being upgraded once you loaded OTA lollipop for F350. So I am going to try this first: http://forum.xda-developers.com/lg-...covery-cwm-recovery-lollipop-booyaah-t3035831

I will try this too, what custom/stock F350 flashable rom are you going to get the system img out of??

I think it doesn't matter as long as you get the unlock bootloader, then we try to flash the official D838 ROM

Yea thats what i thought, i have got the system.img out of Future3.2F350L rom, just making the new zip & about to flash it..

KDZ method still not working for me, but i did get it converted to D838 a different way , using this method as above: http://forum.xda-developers.com/lg-...covery-cwm-recovery-lollipop-booyaah-t3035831 and inserting D838 system.img from a stock D838 lollipop flashable zip i downloaded

And now after doing the above i have just successfully flashed a D838 KDZ via LG Flash Tool 2014 :good:

Finally! Thanks for the test. Now I need to downgrade to KitKat.
BTW, can you post your build.prop; so , I can compare that of F350L. I want to see how going that route - editing build.prop and successfully flashing D383 without downgrading to kitkat. Thanks in advance.

The AT&T D850 is TOT method only that's why there's no kdz at all. Only official lollipop you can get is to insert an AT&T sim.

You cannot update it with a tot file. As there's only KitKat. Your only way is to have an AT&T sim or root / custom rom. Or it might be possible to root and load the update file. Never done the img update file before but if it can be done it would be in the general section.

So is it possible to flash/ install a stock rom after rooting my device?
If yes, can you provide me with the link and some steps to follow.
I will be very thankful to you.

How to install twrp recovery?
Even in future if any updates were released then i need to install either with sim card or flashing custom roms for my at&t model?

if you're going to go through the effort of rooting your phone you might as well install twrp which instructions you can find on these forums or even on twrp website I believe. the link clearly states that it is a stock rom. furthermore the guy was even nice enough to include his own instructions! what more could you ask for.
a little reading goes a long way. personally, I would vote to stick with a stock rom like the one linked above as it will be most stable and support all the features of the phone out of the box.
once a 6.0 rom is released for the d850 it will be real easy for you to wipe and flash that to upgrade again.

Android 5.1.1 Update for AT&T G Flex 2 Unlocked in India.

Alright So I just got the G Flex 2 here in India, it's a AT&T device which is unlocked to work on all networks. the phone is currently running 5.0.1 which is Slow and laggy and heats up bad and I desperately need to update it to 5.1.1 even if it's not the latest one. I'm not too technical and can't flash anything so maybe a simple install package or something is available which would be helpful.
also, since I tried to check the update after manually taking the date forward and took it like 2-3 months ahead I can't check for updates till 2351 hours so maybe a work around with that too, please. I have a stable WIFI connection at my disposal.:good:

you can upgrade with H950PR A 5.1.1 , HAS A POST OF HOW TO MAKE THE PROCESS , I FEEL MY BAD ENGLISH

Flash directly to 11z, .tot presented in that topic is also some debloated and rooted, so near to zero other manipulations.
Btw, search for another Mega Lock dll file, the one mentioned in that topic didnt worked for me.

no no no. dont do TOT
I am in India and am happily running 5.1.1. Claro. I have done this and have a youtube video as well. check it out

Tapnięte.

Is there any way we can update the AT&T H950 variant to this Korean update?

According to a Chinese forum, http://bbs.angeeks.com/thread-3956441-1-11.html
H959(32G) is the same as F510k, they can cross flash the kdz.
But there is no kdz for F510 on the internet.

none from korea here to share experience ?

Well, at least it's happening. Just be patient, we waited for so long and I don't think a few more days will be a problem.

Do not try it even if tot or kdz is available for that..
H950 has qfuse set and anything that is qfuse<1 ie 0 will hard brick the device..
I just hope that there will be some exploit that can give us custom recovery and kernel someday..
However kernel hijacking is a possibility but devs with enough knowledge arent interested in this device ...
Also MM may not have root simply also due to dm_verity in kernel..
For us h950 users outside USA there may never be a MM either...
I was wondering if we all take it to twitter to demand a solution for custom kernel bombing their twitter we may get a good response
We can even say our devices heat up so much that it reaches temp of 60-70+ so we need to modify vdd freely for all g flex 2...
They may acknowledge the sd810 problem and send a method to unlock all variants..
What do u say guys?

I saw a few disappointments ahead when it's fully realised that without a unlocked boot loader we can't root marshmallow.

[Firmware] [V30A KDZ] [D850+D850PR] [All-In-One Thread]

If Any Moderator See This Thread , Please Remove It Completely Because I Don't Know How To Delete A Thread By Myself

I'm confused about your post.. There is NO kdz for the D850.. Also theres already a guide in the general section. The D850 uses tot files and in which there is no MM tot. I think you may be thinking of the D850PR which those files are already in my guide and in which there is risk by downgrading/upgrading a D850 to a D850PR.
So you may want to change the title to D850PR if you keep this thread.

Yeah but it's D850PR firmware not D850. Which can cause issues for some people if flashed on a D850.
Is it rootable? I didn't think the D850 had root unless you downgraded to kitkat to root? (Sorry haven't really kept up with root)

How is it fixable if MM is not rootable? Where you able to successfully flash back to the D850 KitKat firmware? as normally it causes issues with flashtool when changing around models. But you should really mention that its D850PR firmware so those don't get confused as its not an AT&T D850 firmware.

Yes I know its stock unmodified its a kdz I already had the kdz. But looking around MM 6.0 is not rootable on the D850 thats what I was saying, Only way to root is if you downgrade to KitKat. Unless MM is rootable for the D850PR. But it doesnt seem so. I don't have a D850 anymore to test it.

I don't think you read my post correctly, Yes I know how to go back to stock, I created the guide for it years ago What I am saying is you cant fix the cust_error without root and MM 6.0 doesn't seem rootable.
