Your phone is the same as P768 but come with difference baseband. Mine also P768f and if you are on JB 4.1.2, you can easily root it using http://forum.xda-developers.com/showthread.php?t=2338816.
You must unlock bootloader before install any custom rom. read about it here http://forum.xda-developers.com/showthread.php?t=2313794
If you want to unlock boot loader, please follow every step carefully it should work at first try. But many people fail to unlock their bootloader so the result may vary.

1. Normally later version is better. But if you upgrade to JB you will notice reduce in battery life (V20A, V20B, V20C).
2. You do this when you want to restore stock rom. In most case it will restore your phone from soft-brick if you do something wrong with it. There's also LG mobile support tool that can recover you phone.
3. Please read my previous post about how to offline flash kdz

1.in the offline flash guide it says that flashing doesn't loose your phone data - as far as i know everytime i flashed my device with a stock rom (not LG phones) it always removed my data and booted up as if you bought a new phone so how in LG phones you don't lose data?
2.how do i check if my bootloader is locked or unlocked?
3.if my BL is locked so will this thread:

1. If your data is on sdcard, you don't lose it. And for internal data if you don't do factory reset with erase sdcard option your data on internal won't be deleted. But you should take precaution by do CWM backup before messing with these stuff.
2. Can know how to boot your phone into S/W update mode right? It print at top of that screen. If you don't know how to do it. Shutdown your phone, remove battery, hold down vol+ then connect usb cable, hold down vol+ for about 5 sec. S/W update mode show up.
3. For this and all you other question, most of it are answered in L9 forum please take your time a while to read and search for it. I've build unofficial CM and PAC for P768 in "Optimus L9 P760, P765, P768, P769 Android Development" forum. And there're patch from me in general forum to make CM based rom for P760 work on P768.
PS. Please read every step in that thread carefully because you can soft-brick your phone if you do something wrong. But don't worry you can recover it in almost all case but hardware problem.

We don't need to wait 30 minutes ?
Can this unlock be used to test out the CM10 builds on the P768?

Okay, Ive followed all of the guide and it worked. The only issue is that I left my WIFI running before I did it all, so when JB booted up, the phone updated all the apps to JB versions, after flashing back to ICS, the phone refused to boot, so I did a hard reset and then everything was fine. Bootloader unlocked. For some reason after doing all this, when I connect the phone to the PC, it says its a LG-P760 after flashing back to my 768 V10E rom?
I think you should add into the guide that you should turn off all data to avoid auto updates (if enabled)

I see you in four to five different threads doing various things at the same time, and I have replied you in most of them also.
I am sure you are gonna mess it pretty hard and make one fully bricked phone. May be you will be the first one to enter in "hall of fame" :laugh: kidding. this phone is unbrickable but that does not mean you should deliberately try bricking it. he he he
Haha, this is true. I've been doing a lot of things because I really wanted Jelly Bean, and I was trying to get every feature jelly bean offered in case they didn't release the P768 JB update. Now they have released it, I'll stop now and enjoy a relatively stock experience (apart from root + cwm). I also really enjoy doing things to the phone, getting more features out of it etc. It gives me a little buzz
I think I may have already done some things I shouldn't have. The phone has 3 different model names now. Under most it is still the p768. When I connect to the pc, it is a p760, and in some apps, it is a U2. It still works fine though.I'm going to fully flush everything out and start again. And I'm only ever flashing 768 KDZs/ROMs now.
Hopefully I won't be entering any halls of fame for the first bricked L9

LG fastboot for P768
My understanding is that the LG P768 variant, unlike the P760, does not have LG fastboot in rom. Hence the need to flash the P760 rom to the P768 phones to access LG fastboot, unlock the bootloader, and then re flash a LG P768 rom.
Nevertheless, many have managed to root the P768 and have installed CWM.
My question is whether it is possible to use CWM to flash LG fastboot on a rooted P768?

From what I understand, its not something which is flashable. I'm pretty sure its deeper in the phone. Lelus said it didnt work like that. The fastboot mode is just not accessable/present on P768's it seems.
Hey all,
I have a CWM backup of my current rom and have backups of apps and data but am stuck at a bootloop.
As I have read countless articles, it seems my error is because I have a locked bootloader(not actually sure). Though, I only tried to flash
clockcycle's wiped v20d cwm backup file. It failed part way saying it couldn't write to /system.
Since then, I haven't been able to fully enter CWM. just see the red triangle with the droid guy on his back.
I have read Cmahendra's unbricking guide but it doesn't work as I have installed JB and even the tips to unplug, wait 10s and reopen the program to flash again it still won't work. Still stops at 15% saying error connecting to the phone.
There is a similar thread which had this exact problem which said to
use the online method to recover your phone since I had already installed JB. I edited the hosts file to remove the fake offline server and opened up the b2CAppsetup.exe, clicked on customer support,
entered my model LGP769BK and my S/N and it began to start the process and 'analyze' then crashed and said "updating is not possible any longer due to a fatal error while the LG mobile phone software Update"
I've tried to search this out myself and not waste any space but I'm at loss here. If anyone has any help, it would be much appreciated
as I don't have a phone while this is not working.
I've tried all the ways to to hard reset, master reset and still I get the droid guy on his back. I can get to S/w mode like all the other posts say to do but none of those fixes seem to work for me. Am I missing something?
Do I have any options here? I have kind of read that I should just unlock the bootloader but I don't think that applies in my case as I can't turn on my phone fully.
edit: for the online method(LG support tool), it basically cancels when it goes to the 'downloading' phase --> this is what I've seen as most of the answers but doesn't work
Upon further reading,
many seemed to need to replace their u-boot and x-loader
I did so and installed fastboot using Lelus' script here:
http://forum.xda-developers.com/showpost.php?p=41768774&postcount=1
I used option 6 which allowed me to flash the u-boot and x-loader from p760(works with my 769 and others as it says in the options) for JB
I'm not sure if I needed this as I don't have an unlocked bootloader.
I'm not sure of commands in fastboot but I ran
fastboot devices and it showed something
I also ran: fastboot flash recovery recovery.img
and I put one of my cwm backups in the "yours" folder
After I activate fastboot, it brings me to the C:\fastboot\yours folder
I assume this is for me to put my intended files in but I'm unsure if I should use my cwm backup or something else?
After it flashed the recovery img, I sent a fastboot reboot command
but it still went back to the droid lying down with a red triangle.
As some of you may see, I'm not too great with this but I feel like I'm close. Does anybody have an idea of what I should be doing?
should I flash an update.zip?
I don't know many commands but hopefully this gets me going in the right direction.
PLEASE HELP ME!!!!
I guess your cmw restore formatted your system but couldnt load the new system
the recovery you run with a locked bootloader uses a technique called 2nd init which i think is somewhere stored in the system partition. so when the recovery formatted the system, it lost itself too.
I've had a similar problem. the way out would be booting into the SW upgrade mode--switch off the device, remove the battery, remove the usb cable. press the volume up button and connect the phone to the computer. wait for a couple of seconds and then insert the battery.
you should be in the SW upgrade mode
now use the B2C client. if it gives an option to upgrade, use that otherwise, go to the customer support menu and press recovery phone
I have already done earlier. It may have gotten lost in my frenzy of information. I have put the phone into software mode, as you said, and it won't work either; There's no option to click upgrade because it's JB(V20D) and when I click recovery phone and enter my imei, LG mobile support tool(B2capp.exe) analyzes and then has a 'fatal error'
Since I flashed the new u-boot and x-loader my screens are all backwards/mirrored. Maybe the tool flashed an unlocked u-boot and x-loader if that's possible.
Is a recovery possible by fastboot?
I have a clean and full copy of my cwm recovery as well as apps and data backed up, I just need to get this phone in working order

If you fastboot flash the u-boot and x-loader from p769(ICS) it should go thru with the offline flash detailed in cmahendras guide.
http://forum.xda-developers.com/showthread.php?t=2085344
Use the KDZ_FW_UPD.zip from this thread
Or try this
Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that

Use the KDZ_FW_UPD.zip from this thread
Or try this
Remove all of the stuff you have downloaded for this. Download the original B2C client from LG's site and use that

I have the updated kdz fw upd .zip from the unbrick and root thread as well as downloaded a new, official B2C client but they all still hang at the download part during phone recovery.
Tablechair, that did the trick.
Is this because the tool we use to flash for the offline method doesn't recognize the x and u-boot loaderse of JB?
After I installed the ICS boot loaders, my software upgrade mode wasn't mirrored anymore.
I did as tablechair and flashed the V20D.
Does anyone understand why this problem happened in the firstplace? Maybe I didn't get a full copy of clockcycle's backup cwm
or should I have not flashed his recovery in the first place since I didn't have an unlocked bootloader?
Again thank you for all your help and if anyone can provide answers to my other supplemental questions, that'd be great.
Off to root and probably unlock bootloader to be sure.
edit: I can't find the thanks button. but thank you very much tablechair. much appreciated. Hope this can help someone else
p.s. also big thanks to those who made the fastboot program for p769(Artas182x and sguerrini97). really an invaluable tool as I now know.

Things don't always go according to plan, maybe his Clockworkmod backup was made from the touch version and he didn't have artas182x second init recovery installed. So when the cwm failed the first time, did you try to restore your cwm backup?

Not yet. having problems flashing a kdz again. I've tried the 2 different software modes, as well as setting emerg and diag but still getting stuck at 15% again.
Do i have to replace my uboot and xloader with the ICS ones every time I want to use the offline flash method?
edit: yup, after replacing with ICS loaders again i'm able to flash using software upgrade. will update on whether I can restore cwm

I realized I misread your question. When I flashed before the incident, it failed to write to system and I didn't restore my other folder. I rebooted and it was all missed up. Anyway, now that I've got everything back and now with an unlocked bootloader, i was able to recover my old image. However, data isn't working so I have to find the radio to flash as I recall reading in other threads.
Can someone explain in laymen terms why this is? recap, i was on unlocked bl rooted jb and I flashed my old cwm backup when I was rooted but had a locked bl. My apps and messages were all there but the radio was different. I'd understand if I was going from ICS to JB but I was on JB both times. The only difference being a locked BL. It's got to be something about the Radio from p760 or V20B that didn't work on my earlier backup or something like that because the layout status bar is different with a "data" button and showing H instead of 4g(which are the same afaik).
Since, I restored to my backup from after my bootloader unlock and root so data is working showing 'H' with the different layout
Also, I had problems backing up and restoring until I noticed that it works better when I power off the phone and do the manual commands to enter recovery as opposed to using the app to send me to recovery(where I incurred /system backup errors).
My last question is which cwm recovery should I use? I currently have the one for a locked bootloader installed as per Artas182x's website. On that post he has a link for an unlocked bootloader recovery on the xda forums but that thread was updated to not working. Are there any disadvantages to me using a locked bootloader cwm recovery?
I don't think I have any option but to try it as I want to flash CM10.1 for p769. I also read that if your bootloader is unlocked, you can download the cwm from the googleplay. If this is true, can I just install over or should I uninstall the Artas182x locked bootloader one????
update: have to remove l9 recovery by deleting the appropriate system folders and then flash the appropriate .img through adb commands
Help.

Although I might be late, I have the same problem and the same phone and I really need help. I have a soft bricked phone lg optimus l9 and I had the same problems that you had exactly... Which is weird exept I don't have Clock Work Mod or anything ... If you get this I would really appreciate some help. Thanks
yup me too
I finally got software upgrade to work with my lg p769 that was security error cuz i still haven't unlocked the bootloader, if i knew what a good job lg and T-Mobile did in locking it i would have waited and got a g3 that my buddy rooted in like 5 min and unlocked the boot....
What worked for me is this LG FLASH TOOL 2014 THREAD ON XDA
http://forum.xda-developers.com/showthread.php?t=2797190
flashed both the 20H and 20D successfully i uninstalled everything lg in the control panel first though.
Hope this works for you cuz i was struggling on and off for a month to get this far lol
the 2014 tool ultimately worked for me too, once I fixed a couple things. I had rooted and forgotten to unlock, so it was at Security Error, and it would also disconnect at 15% .. in the 2014 tool, I had to install all the updates even though I'm in windows 7 or it would keep doing it. All good now.
I have been trying all these methods and I am still not able to get in the S/W upgrade mode. The only thing I am getting from the device is being able to put it fastboot mode (The inverted one). I really want to revive this phone
Thanks in advance for any help given

Hey, it's been ages since I have done any of this but IIRC, if you can get into fastbood mode u can still get into software mode,
- turn phone into fastboot mode
- open the software upgrader thing as you normally do
- maybe switch emerg to diag or something like that
- this part is where it's slightly different than the normal way(same program but u select a different option than the default 1st option on
I think if yoiu look through the tutorials it does mention an alternative method for getting into software mode
in one instance in my past, i had to reflash the ICS boot drivers so the software installer would recognize that
the flashing of the ICS boot drivers is done through fastboot. Should be a post in my history where I asked a question regarding this.
Sorry for the chaos but maybe this will help you get in the right direction since I don't know any of your phone history and what you've done etc
best of luck mate

Hey, I have been trying it with the fastboot but it keeps timing out and not allowing me to finish. One thing I should let you know is that, ever since I had put the device in fastboot, I am not able to get back the S/W upgrade mode. Dont know if that will help in seeing what my problem is or if you want me to explain everything from the beginning again, I am more than happy to.
Have you followed the steps that I linked to in the first 3 posts of this thread?
Follow the steps to flash the ICS bootloaders in fastboot and then you can do the fastboot trick for getting the software to recognize your device.
Right now your phone has the JB boot loader on it and is thus not recognized by the software.
recap:
step 1: flash the ICS bootloaders in fastboot (look at the linked thread in post 2)
step 2: use the software in emerg or diag mode but sitll follow the same steps as the tutorial. I think my earlier posts should explain precisely.
if you dont flash the ICS bootloaders, it won't be recognized by the KDZ installer

Okay, this is my first thread on XDA, the reason I'm making it is there is a lots of problems with progressing to lollipop. All of this is already mentioned in the forum, but this way it is much easier since it is all at one place. If I'm doing something wrong please warn me with explanation how to resolve the issue. If I'm posting in wrong forum section please move my thread where it is supposed to be.
1. Before doing anything check if your phone is ready to get updated:
1.1 Do you have a stock Kitkat rom or at least a rom that is kitkat based, since there can be a problem with partitioning if custom lollipop rom is installed
1.2 Create a backup. Don't be lazy LG backups will not help you since they can't go from kitkat to lollipop, don't try to do it from recovery because you will lose custom recovery. Copy your files from phone including extracted contacts, and back it up online with google or some other backup providers.
1.3 Check if you have a latest touch firmware, because you might have a problems after installing lollipop and it will be hard for you to check for updates since your touch might become useless.
1.3.1 To check it go to hidden service menu by typing 3845#*802# and go under HW Device Test, then Touch Test then touch firmware version and write everything down. After that go to touch firmware upgrade and after 15 seconds compare the touch firmware version values with those you written down.
1.4 In hidden Menu you can also go to wlan test then ota setting to check if it is disabled on your phone. After that check again if there is OTA updates for your phone, and also check if there is PC suite Update.
1.5 Check your phones version if it is D802, D800 or something else, and check which rom you have installed. You can do this in settings about phone or if you are happy about hidden menu found, go there and into settings then version info. This might not be interesting or fun to do, but it will save you the trouble if something goes wrong, because you will know what to ask.
1.6 Last but not the least, before starting to flash fill up your battery, i've read some posts that say there are problems with wrong capacity shown, and a lots of battery drain problems, and only solution till now is to have a full battery on start.
2. You will need LG FlashTool and of course installed drivers for your G2 on your PC.
All of that you can get in the thread by @quangnhut123 .
2.1 Just a bit of precautions, don't forget to always copy a kdz file in to Flashtool folder and then start a tool. All should look the same as in that thread, except you should always use CSE method because with this method you will install kdz from scratch, removing everything from the phone.
2.2 You should find the kdz file which suits for your phone on site . You can check for kdz by typing in imei in check new firmware section or find the one for yourself by searching the site. v30a is lollipop open while v30d is for branded G2's.
(I've read that this site is not allowed by Xda moderators, so if I can't post it please give me info on where should we download kdz's from).
2.3 I think it's all pure logic now but lets say it one more time. You have downloaded kdz file, and put it inside LG Flashtool folder. You should now start Flashtool and get your phone into Download mode. To do this you need to hold volume up button on turned off device and connect usb cable while holding volume up. Now just cse flash.
2/3 This is troubleshooting step, if you have a problem ask and i hope this great community will help you like they did to me, and ofc I will do my best to help.
3. Now we go to rooting.
Here is the thread by @avicohh which worked for my D802.
Just follow his step by step tut and you will have a rooted phone
3.1 The only issue that might happen here is you are stuck with # and adb waiting for your phone. To resolve this just go into download mode manually.
4. Okay rooting done, now let's go to custom recovery install
It's easy as installing an app from google play by @bender_007
4.1 After installing it open the app and follow the on-screen instructions. If it fails for the first time, try it few more times, it will eventually work. (OFC. I didn't install it with only one try).
4.2 To get into custom recovery hold volume down and power button till first LG sign shows up, then release both buttons and quickly press them again. It will ask you do you want to do factory reset, press yes and yes again, and it will get you to custom recovery if you installed it.
4.2.1 If you factory reset your phone that means you didn't install recovery correctly and you will lose your data, but again that should be no problem since you have that backup from the start.
Now optional steps:
5. Install system app remover to remove bloatware from your phone. You can do it manually but this way you will have those apps backed up.
6. Next suggestion is to install a few mods if you need them. In my case I had to have a Plug and pop, since it is lost from Lollipop and I loved that feature. Here is a thread on how to install that mod by @p_a_r_s_a7
//That's all, if you have any questions feel free to ask, since there is no dumb questions, but also try to read carefully before//
Thanks to:
@quangnhut123
@avicohh
@p_a_r_s_a7
@bender_007
A lot of others whose names i can't remember. If anyone else needs to be mentioned PM me and i will add you in this section.
I will add pictures and stuff if needed
Thanks, good all-in-one thread, + easiest methods. Ill recommend it‚to others
This forum is such a mess that a thread like this is like a fresh breath of air. Every advice given on other threads references something that you should already know how it's done, or you should already have done to your phone in the past and have a certain version of it, or non-working tools that are only around for a few months until an update makes them unusable.
No wonder that most of the first-page topics, including pinned ones, have the word "brick" in the title. This should signal the forum moderators that something is wrong around here.
My phone is stock international sim-free G2, never rooted or otherwise modified and yet no one was able to offer a coherent solution of how to update to Lollipop, until your post.
So, thanks for this thread.
Thank you, that is exactly why i made the thread. Every one of those threads has everything explained, but you need to search theough 150 pages to understand how something is done. That's why i wanted to make a thread with all explanations made in a single post and to make it noob friendly since the worst thing that happens in other threads is answer like use a search you have it somewhere.
Hi,
Thanks for the thread. It really helps noobs like me, but I still have a couple of questions...
I was running Paranoid Android L rom with root, twrp and kk bootloader on My D802.
I didn't see this thread before I decided to downgrade back to 4.2.2 stock rom, and now I don't really know what steps to take.(I have kernel version 3..4.0 and build number JDQ39B)
I haven't seen an OTA available, so I was thinking of flashing new Lollipop rom kdz file. But I've been seeing stuff about using LG PC suite to upgrade via OTA so i wasn't sure.
So my main question is that do I do an OTA upgrade on my current 4.2.2 stock rom or do I download an official Lollipop rom? Can you give me a brief idea of the steps to take?
Thanks

Updating through pc suite or ota is the best way if it is available to you. Flashing kdz is the same thing but that is doing it manually while through pc auite nad ota is pretty much automatic. Anyways which ever way you decide to use be sure to fully charge your battery and factory reset acter the update. If you need anything else feel free to ask

No need to flash bootloader if you didnt flash it for paranoid android. And definitely no need to root since you can root after update.
Problems with flashing KDZ
I have downloaded Spain Lolipop KDZ file for LG G2 D802.
Have backed up everything usint TWRP> ( Presently on Optimus G3 rom v 1.4.1 with dorimanx kernel and TWRP )
I have copied the KDZ file to the flash tool. When i use CSE flash .. it takes me to the next page .. in which I click on Start which then opens up the LG Mobile support tool.
Then it shows detecting ur phone .. unpacking or extracting file .. after that shows software updating .. reaches 2 % and then shows error .. asks me to retry .
Do you know what I am doing wrong ? or the cause of this prob ?

Had the same problem when flashing kitkat kdz. Are you sure that you have pasted kdzfile inside flashtool. If that is not the problem try other kdz. That helped me
Where are you from and more specifically whhere your phone is from so i can maybe help you with finding right kdz. And btw i think you might have a problem when trying to restore that backup so if you still can backup your phone manually or on the cloud.

Hi again..
OTA update to Lollipop has failed on my D802, LG PC Suite only upgraded me from Android 4.2.2 to 4.4.2, so can anyone help me out here?
Am I missing something for OTA update? If not, then which lollipop kdz can I download for my phone so that I can flash? I live in UK and i use a 3 UK sim if that helps
but also, In the process of trying to boot into my previously installed TWRP recovery, I discovered that i have been restored to stock recovery. I have rooted the phone, but just wanted to clarify: I flash custom recovery, then bootloader/kernel then lollipop kdz?
Thanks again

I am not sure but i think that update for the uk didnt come out yet. so you can't update to lollipop yet via pc suite or ota. and you got it all wrong. first you flash lollipop kdz but you will have to try out few of them since official for uk didn't come out yet, after that you root, and then flash custom recovery.
and as previously you will be back to stock recovery after update. you have it all explained step by step in first post. i know it is a bit long but that is the best way, since i didn't want to write stuff like "you should know that" and so on. so just follow the first post and you will be happy, or wait for official uk update over the ota you will be happy too, and i guess it should come out in a month.

Thanks for the quick reply.
I'll download all the lollipop kdz's and see which one of them works for me till the UK one comes out then I'll just do a normal flash over it.
But seriously, one month for the UK ota :crying: Right now, I don't even know which is worse: Google that takes forever to release updates with so many bugs, or Apple who generally release better stable updates but make older devices laggy...

its a good update, not that buggy, and be sure to fully charge your battery before the process. you should try europe open or something like that, but there is no german or uk release yet and some guys suspect it is slowed down because they found out bugs in other versions

Where from is your phone? Are you sure you flashed right kdz? Did lollipop even turn off? DidCSE flashing finished sucessfully? I would like to help you, but i cant if you dont explainme what is your problem. I am not some pro who faced every error on every phoneso please explain a bit more
And i suppose that erasing screen could have been factory reset on stock recovery

I believe mine is an international version. Where it came from, well, I'm from the Philippines and I got my phone from a local telecom, Globe.
The flash tool said that it was successfully upgraded, but judging from the phone's behavior I think there's something wrong. My phone never started successfully, and I got stuck in the LG logo.
Hi,
I tried to upgrade my US998 from Oreo to Pie using LGUP patched. The upgrade process went well until the phone restarted and have this error message:
"Your device has failed a routine safety check and will not boot..."
I did try using LG Bridge to fix = not working
I did try fastboot boot laf.img (using extracted laf from H93031a_00_OPEN_EU_OP_1105) not working.
Any other solution?
Thanks

If you have fastboot, why don't you flash a recovery and a custom rom? Ik stupid but it's the only thing that comes to my mind since i don't have a LG phone lol

Is that "Download mode" the same as the Samsung one? How do you NORMALLY access it?

I'm not sure. Normally I access download mode using volume up and power button. The download mode was there for a sec and then the screen back to
"Your device has failed a routine safety check and will not boot..."
again.
Ah ok so now I understand.
But why don't you unlock your bootloader then if fastboot works? Do you know for sure that TWRP doesn't work?
I really want to help but I don't have a LG phone

EDIT: The LG Bootloader unlocking page is "under construction". Guess you have to bring your phone to LG for them to fix this...

Unfortunately my LG V30 is US region. The official bootloader site not support my phone. Thanks for your info anyway
I'm not sure why a Samsung user was recommended this post. And no offense to the Samsung user, but the process for unlocking, etc is VERY different for Samsung than it is for LG... so I recommend not worrying about that. Believe me, I know, because I'm researching switching to a Samsung in the future, and the process is very different!
That being said, the best resource here is the WTF thread with the post by ChazzMatt. That post has everything you need in one place.
jacoozie, the error you're getting indicates that you had a non-stock phone when you flashed the KDZ on an unlocked phone. For this reason, it's no surprise you got this error - the phone must be COMPLETELY STOCK for a stock KDZ flash. I'm guessing you had TWRP or something else installed, which is causing this problem. Once you unlock, you cannot just flash things willy nilly... and generally you don't flash with KDZ unless you're trying to change models (aka Frankenstein) or on the way to a custom ROM.
It sounds like you've done some unlocking rooting... if so, I recommend you start over with the WTF thread, read it VERY CAREFULLY and ENTIRELY and then reflash as instructed there. I'm guessing you may need to go back to KDZ Nougat and then work your way forward. If you have questions, ask in that thread... but you shouldn't have any questions as the thread is VERY complete (been updated all the time with very detailed information, so everything is in there).

Thanks for the reply.
I didnt install TWRP or any recovery tools to my phone. My phone bootloader still locked thou.
I have read the WTF thread but the problem is I cant get into my Download mode.
Ok, what steps are you using to try to get into download mode? Presumably turning off the phone, then holding the volume up button and plugging in the USB cable (other end already connected to a Windows computer), correct? If that doesn't work, can you try other USB cables? Sometimes a bad cable could prevent the phone from going into download mode.
