(FlashKDZ/Root/Recovery/Hiddenmenu/troubleshooting) (noob2noob guide)
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

@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...
Thanks again for all the help.

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

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.

You can flash stock rom by using lg up and kdz. Make sure you use the correct kdz file for it.
Keep in mind, KDZ flash will erase your data, so be aware of that.

Yep. If you can get some kind soul on here to extract the stock recovery and turn it into a flashable zip, then you can download it, boot to TWRP, flash it, and viola -- stock recovery.
It doesn't matter what model recovery is from -- they are all the same with the EXCEPTION of the H932. If you have an H932, you must use the H932 recovery. You won't brick your phone, but you will be flashing a KDZ if you ever want to take OTAs again. Also, if you don't have an H932, do not use the H932 recovery -- same outcome.
EDIT: if your phone is rooted, you will not be able to take OTAs (the hash check will fail). So, if it is rooted, you need to unroot it (install Magisk manager) before flashing the stock recovery and taking OTAs.

Ironic you wish to remove TWRP from your phone when for several months that's what we would have given large sums of money to have. Finally in May 2018, the WTF exploit allowed us to do that. You can root your phone, since you have TWRP and install recent TWRP-flashable zip based on stock firmware.
But if you wish to return for full stock without TWRP custom recovery, you will need to use LGUP to flash stock KDZ. And yes that requires a PC.

I'll have to let one of the Korean users answer that. I'm not an expert on the Korean models. They have to do extra step to get TWRP, root and get radio back. So if your phone works and has TWRP then at over point in was rooted with Magisk.

If you are going to keep TWRP then I won't bother, but if you want to go back to stock let me know and it just so happens I have that KDZ sitting in my archives so I don't even need to wait 40 years for lg-firmwares.com to download
Just ping me and I can make you a flashable zip that will take your phone back to stock without having to flash a KDZ.
Again, I am not going to bother right now since it sounds like you may actually want to keep your phone as is.

Sorry -- I just haven't had the time -- and it doesn't even take that long. I have a few minutes right now, let me see if I can throw something together for you.
Keep in mind, that I have no way of testing it. It won't brick your phone, but I might have a typo and it will just fail (I have a tendency to have typos ;P ).
If that happens, you will just have to tell me where it is failing, and I will fix it. *crosses fingers that I have no typos*
EDIT: I am not going to do something half assed. I am grabbing the latest firmware available on lg-firmwares (V300K21r) and going to make a FULL zip.
As long as you don't wipe data, even if you are on a lower version, you should be able to flash it and keep your data. I will flash all the partitions that usually get flashed when using a KDZ.
I should have it up in about an hour.....
EDIT2: It is up -- https://www.androidfilehost.com/?w=files&flid=286970
Download and flash that in TWRP. Wipe cache / dalvik. Reboot and you will be fully stock. Again, you should only lose your data if you factory reset or wipe / format data.
Enjoy,

So, got my V30 here, Frankensteined H931 to US998, never had basically any issues with it so far. Decided to attempt to install the TWRP flashable US998 30b from John Fawkes and that's when all hell broke loose. But I won't get into all that, here's the primary issue now:
I get Download Mode when I power the V30 off and hold Volume Up + insert USB cable (and I've done this with multiple USB cables as well as multiple USB ports), but I never get a connection to the computer anymore in that mode. Nothing, no connects at all, no sounds to indicate a connection, while the V30 shows it's in Download Mode and is waiting for a connection.
If I power it off back to TWRP (3.2.3.7, just flashed earlier as instructed because of the Pie attempt), I get all the proper connections, sounds, etc, can copy files over to the internal as well as external storage, no issues.
Normally when most people say they can't get into Download Mode it's some issue where the device won't power on into that mode when the USB cable is attached - that's not the case here as stated: it powers on and says Download Mode and waiting for a connection, but regardless of any USB cable or port there's never a connection.
I'm suspecting it's a software issue since obviously on a reboot into TWRP the USB port works exactly as expected.
Any suggestions? Because of this I'm unable to do a clean proper US998 20h KDZ flash or the 30b KDZ flash either so thankfully I did have a backup of my previous 20h Oreo install. Of course, because it's all pooched now that is effectively useless because of course of the encryption and upon restoring the backup it won't boot because of the password crap and forces me to format DATA and start all over again.
/me hates encryption when this BS happens, seriously...
So, any tips or tricks that might get me back to a working connection with Download Mode? Flashing a particular partition or something? I'm basically about to redo it with a clean 20h TWRP flashable here in a bit, not left with many other options now.
Anything is appreciated, thanks...
1) Try flashing US998 20e TWRP-FLASHABLE zip. See if that gets you download mode back.
If not, then
2) Try different LGUP.
______
After you get Download mode back, try these steps. Helpful people been testing this out...
For users with TWRP who get stuck on LG logo.
* Flash Verizon VS996 Nougat Partition DL -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose all partitions!
You will probably lose download mode, but you've prepped your phone, corrected any partitions. (This is not just for Verizon users, this is for all North American variants -- except for T-Mobile H932.)
* Flash US99820e TWRP flashable zip to get back Download mode.
* Then REFURBISH to US998 20h KDZ.
* Now flash TWRP recovery again and then flash John's zip US99830b.

See Instructions above. Going to write something up in the US998 thread.
Yah, the 20e thing got download mode working normally meaning when the device went into that mode I'd get the traditional notification from Windows that a USB device was now attached - that's what was missing previously for whatever reason.
So I flashed 20h clean with the dev patched LGUP, no issues with Partition DL because I wanted it truly clean without anything that shouldn't be there, and that meant the factory recovery partition as well.
Then I attempted to flash the 30b KDZ, no joy, just stuck at the LG logo and I've wasted enough time on this now so, I'll just wait till some other point and maybe give it a shot in the near future.
Kinda sucks starting over totally clean but hey, this phone has worked near-perfectly since I got it in May so it'll be fine with a clean fresh start. I'm not even going to install Magisk this time, I can't think of a single reason I even need root anymore but if I do I'll worry about that a later time.

Yah, the 20e thing got download mode working normally meaning when the device went into that mode I'd get the traditional notification from Windows that a USB device was now attached - that's what was missing previously for whatever reason.
So I flashed 20h clean with the dev patched LGUP, no issues with Partition DL because I wanted it truly clean without anything that shouldn't be there, and that meant the factory recovery partition as well.

You need to do the VS996 Nougat Partition DL step. It preps the phone.
This is what you need to do:
I have all the steps above. The first 20e flash was just to get Download mode back.
ChazzMatt said:
After you get Download mode back, try these steps. Helpful people been testing this out...
For users with TWRP who get stuck on LG logo.
* Flash Verizon VS996 Nougat Partition DL -- EXCEPT for Recovery partitions, to keep TWRP. Do NOT choose all partitions!
You will probably lose download mode, but you've prepped your phone, corrected any partitions. (This is not just for Verizon users, this is for all North American variants -- except for T-Mobile H932.)
* Flash US99820e TWRP flashable zip to get back Download mode.
* Then REFURBISH to US998 20h KDZ.
* Now flash TWRP recovery again and then flash John's zip US99830b.

Let me start firstly by saying, thank you ChazzMatt! V30 owners around the globe are incredibly fortunate to have your dedicated write-ups and support for these terrific phones. FWIW, I'm seriously impressed with the level of knowledge and your willingness to deep dive issues with folks... thanks again!
Getting to the topic however; I have the identical issue occurring with my LS998U (V30+) that I just went through the unlock process with yesterday. This morning I TWRP flashed the VS99630c ROM and everything worked A-OK except download mode. Exact same symptoms as br0adband is describing - phone appears to enter download mode as normal (though the initial "LG V30 ThinQ" boot screen appears to have replaced the bootloader warning screen?) but is not initiating the USB port for a connection at all.
Connections are established and work normally in TWRP and when booted into the OS so there appears to be something fundamentally wrong with Pie or the flash method.
I'm 99% confident it's not a PC side issue as there isn't even a connection for LGUP or drivers to fault out on.. I also tried my other US998 phone which is on dotOS and everything worked normally.
I'm about to try the TWRP flashable 20e per ChazzMatt's suggestion and will report back if I have success (or not).

VS996 firmware doesn't have bootloader unlocked warning. Verizon never thought it would ever be unlocked.
While flashing 20e should give you download mode back, to me or seems both of you are sort of missing the point of the preliminary VS996 Nougat Partition DL flash (while omitting the Recovery partitions to keep TWRP)
Maybe in your case you don't need it -- since you made it to the other side of Pie, but that Nougat flash fixes any Partition problems. Just be sure to keep TWRP during that.
You may temporarily lose download mode again
Then TWRP-flashable zip US998 20e fix that.
Then REFURBISH to US998 20h. You'll temporarily lose TWRP at that point.
Re-Install TWRP and the three root files.
Then flash US998 30b TWRP-flashable zip.

While my "missing the point" is entirely possible ChazzMatt, I was under the impression that I was already AT the preliminary Nougat step after having just stepped through the Frankenstein and unlock methods?
My progression through those steps was simply;
Frankenstein per your post here; https://forum.xda-developers.com/lg...ssflashing-t3780969/post76510671#post76510671
Unlock the bootloader, install TWRP et. al. per your directions here ;https://forum.xda-developers.com/showpost.php?p=76584629&postcount=193
Upon completing these steps, Nougat is already installed at which point I figured I was ready to flash VS99630c. What am I missing here... should I have reflashed Nougat?
I didn't have any issues like others are reporting with the upgrade to 30c (TWRP flashed it flawlessly and it booted right up).
It wasn't until I decided I'm not ready for Verizon Pie (tastes gross) and went to step back to US99820h that I realised Download Mode was broken.
Is all of this not just a case of Download Mode being broken in 30c for everyone?

Does Download Mode work for anyone after this step or is TWRP back to a 20 series ROM the only way back to a working LGUP?
Sorry if I'm only confusing things more but I figure I'm not the only one tripping up on this... once I understand it better, I promise I'll step in and help educate other folk
It really is true about ChazzMatt's willingness to help around here.
What I never could understand is why some users, after receiving help AND successfully using it to fix their phones, don't even bother saying thank you. I'll happily spend my daily Thanks quota on helpful posts, even if they have no relevance for me at all. And I see Chazz do the same, every day. Others too, of course. But it seems some people feel being thankful is beneath them. Or something... I just don't understand it.

No, download mode isn't broken for everyone. Most people flash to Pie with no issues and download mode still works. It's when reverting to US998 Download mode seems to go away for a number of poeple (not sure how many and may depend on the LGUP used)
_______
OK, if all you wanted was for Download mode to be restored and you had no problems getting to Pie before that, then ignore what I said.
I thought you were trying to get to Pie and couldn't. In that case the workaround involves flashing Verizon VS996 Nougat -- NOT US998 Nougat like in Frankenstein -- via Partition DL mode except for Recovery partitions. That's a necessary prep stage for Pie. Both people in this thread weren't doing that. OK, so you had good reason. :silly:
THEN going to US998 20e via TWRP flashable zip, which restores Download mode. But if the goal was to get to Pie (yours wasn't) flashing 20e to get Download mode was also step zero. It was also necessary to restore Download mode so you could then flash VS996 Nougat via Partition DL mode (except for Recovery), to then flash back US998 20e TWRP flashable zip AGAIN, to then REFURBISH to US998 20h.
The VS996 Nougat part is important for those people hitting the LG logo wall.

This is good news... thanks for confirming!
I've likely done a few hundred ROM flashes and plenty of roots/unlocks in the past 15-20yrs and this was the first time I had a genuine "Oh crap" moment where a low level mode like Download Mode truly failed.
I was also having trouble getting back into TWRP (Noxx PM refused to work on 30c) which fostered a rapidly growing concern that without TWRP and Download Mode, I was effectively bricked (or at least in for a few hours of work to find a resolution).
I breathed a sigh of relief when attempting a Master Reset led me back to TWRP... I still had options!
Anyhow, it's probably fitting for me to exit this thread on the same subject I entered on by saying thank you again for the information share and willingness to help out :good:
Cheers!

Update : I have KDZ 99820a using LGUP and locked bootloader I'm back to stock is there any issues if I update to the 99830b which is the original software that the phone came with? Can I perform that update via KDZ?

Losing your download mode has nothing to do with stock.
Why did you lock your bootloader back? You can run stock rooted firmware just fine and have lots of advantages like DTS surround sound stereo.
I don't understand why people lock the bootloader back just because they decide they don't want custom ROMs. The best thing to do is run rooted stock firmware, have everything you want.

Don't get me wrong i like having rooted devices because of the endless possibilities it offers but this time mayor newer games that are coming out they have the ability to detect if you are rooted or if your bootloader has been unlocked and they kick you out of their servers, that's the main reason why i want to go full stock, and I was so afraid to do so because some people are reporting when moving from oreo to pie it creates bootloop and since I had issues when I was rooted and flashed via twrp 99830.zip download mode won't detect the USB cable only when I rolled back with LGUP to oreo downloadode started working and I KDZ oreo to have official recovery and relocked bootloader but I want pie is just I am not sure if I can go up with LGUP to pie using 99830b (which my phone originally came with pie) from 99820b
Could you please help me with the same problem with download mode on h932? I'm on stock pie now. I want to downgrade to nought but my PC not recognize phone in download mode. Thank you.

First try a different USB port, different cable and/or different computer. If you never rooted the phone, there is very little chance that your actual Download Mode got corrupted, and one of the above will most likely solve it (although many doubt it because it sounds too trivial).
Also, make sure you're using the latest Dual Mode Dev patched LGUP from one of ChazzMatt's ROM threads.
Next I would try the Update Recovery mode in LG Bridge (on the Update tab).
Finally, if none of those work, you can try force installing the Pie OTA using LGUP FOTA mode (doesn't require Download Mode). It's described in the thread linked below. Best to read the whole thread for context, it's just a few pages.
[H932][T-MOBILE] URL for the H932 Pie OTA file
https://forum.xda-developers.com/lg-v30/help/h932-url-h932-pie-ota-file-t3991417
Hopefully one of those will work for you. Please report your results, regardless of outcome.
Good luck to you :fingers-crossed:

I tried all things with cabels, PCs and drivers, i'm not sure but as i know LG phone in download mode should be recognized as anything, but in my case i have no any devices in the device manager. I didn't root this phone but i bought it with unlocked bootloader so it is possible that it was rooted. I tried lock bootloader but it didn't helps so i unlocked it again. Now i'm going to try to flash OTA file. Thank you so much for help.

Does Download Mode start on the phone?
Just to make sure: From Power off, press and hold VolUp while plugging in the cable. Then load LGUP. Again make sure you're using the Pie compatible LGUP from one of ChazzMatt's ROM threads.
Otherwise I'd try LG Bridge next.
As for force installing the Pie update with LGUP FOTA (the thread I linked) we've only had one confirmed case of it fixing Download Mode so far, although not many tried it yet. On Oreo we had many users confirming it, but Pie is different.
I should add that if you have working Pie, but just would like to roll back, there is a risk that the FOTA will mess up what you have. So if it doesn't fix your Download Mode, you could be worse of. Just a heads-up

Actually the main problem is that phone doesn't recognize by PC when download mode is on the screen. I have tried to use lg bridge to recover, but anyway it reboots my phone and then my phone doesn't recognize. Now i'm trying to solve lg up error with FOTA update, it looks like wrong dll file. I'll keep you up to date.

Good day everyone, I'm new here so i hope i'm posting this right
This month i got an LG V30 V300S (korean variant), it was supposed to be H930 but they sent me this one instead, it didn't bother me much at first since the phone supports my country's frequency and XDA still supports the korean variant V30s, and I can't return the item too cuz of pandemic.
I came from the LG V20 so I'm quite familiar about cross flashing, but even before that i still did a little reading regarding on unlocking and rooting the phone on the V30 XDA thread (kind of easier than the V20 tbh).
The first thing i did was unlock and root the phone, installed TWRP and installed V300S firmware
(Based from here: https://forum.xda-developers.com/lg-v30/how-to/korean-variant-bootloader-unlock-root-t3804505)
It was ok at first, but now i decided to cross flash to US998 30b (Pie) via TWRP because V300 firmware is full of bloatware , and i stayed there for a few days.
Now i was wondering of installing Custom ROMs on the phone, it was a messy thing for me to understand, but as far as i knew since i want to install Android 10 based roms (Havoc OS), i needed Stock pie blobs.... Unfortunately it didn't work, i ended up in a bootloop, so i went back to US998 30b again.
After a while, i wondered that maybe the whole crossflashing is wrong? So i backed up the phone and flashed an H930 31a instead, but has no signal
Previously i can just easily bring back the modem using backed up V300S modem via LGUP or TWRP, but this time it didn't work, i also picked an older version (H930 30q) to match my phone's modem version, still no avail
And even disregarding the signal, i attempted to flash the custom rom again... Still bootloop
So I gave up at this point, and decided to go back to US998 30b, but this time i can't go back to US998 anymore, it also bootloops
I don't know what i did wrong now, i just followed the same instructions.
V300s > H930 > unlock > TWRP > US998 (TWRP)
Only difference on this one is i no longer flashed V300 kdz cuz i don't have one
So now I'm stuck at V300s_21e_Oreo cuz it's the only ROM that worked
I know I'm doing something wrong here, but due to a lot of procedures i have done I don't know where to start anymore, the phone is fully working with signal right now, but it lags on this ROM, US998 30b was way snappier
Sorry for the long post, I'm just desperate
Any help or suggestions will do.
Update: managed to go back to US998 Stock pie (30b) no idea how, 4G is painfully slow but i guess this will do for now
I got an odd problem going on here..... So i used lgup to update to a newer firmware worked fine booted fine so decide okay im ready to flash twrp & do so with no problem. got all the encryption stuff out of the way & was ready to flash a new rom so i do it. I reboot my device & ive tried this with 2 roms they both bootloop & ontop of that i flashed the zip version of the kdz us998 everything flashed fine. Reboot. Same thing bootloop so now i say okay im just gunna go back to stock but now the firmware update or download mode will not connect no matter what i do & i had just used it with no problem i think the zipped kdz flashed something that is making it unable to communicate. I cant see any way out of this im bricked but i got recovery theres gotta be something i can do. appreciate any kind of help thanks
Even though you wrote a lot, regrettably you give very little useful information. And you have almost one long run-on sentence. Makes it hard to read.
First, what variant do you have? Do you have a US998? Or did you previously have another version -- like AT&T H931 or Canada H933, which you converted to US998? As you know, you can't just flash LOS custom ROMs to those two variants without extra prep steps. Read the V30 custom ROMs FAQ -- which you were told to read when you used the WTF instructions.
Were you trying to flash LOS-16 ROMs or LOS-17 based ROMs? You need to be on last stock Oreo firmware for LOS-16 and on stock Pie firmware for LOS-17 ROMs. You said you flashed "newer" KDZ firmware, but don't say WHAT you flashed.
Nor do you say which ROMs you tried to flash.
Later, you say you flashed zip version of US998 firmware. WHAT zip version did you flash? 20d, 20e, 20f, 20g, 20h, 30b?
Flashing US998 Oreo 20e zip will give you download back. Boot into TWRP and flash that. But you need Magisk 18.x or you may bootloop. If you have later version, uninstall Magisk in TWRP and reinstall 18.x.
And answer all the questions.
