hi v10 folks,
just bought this v10 mobile 3 days before. it came with 5.1 android version, so thought of upgrading it and found some weird observations.
1. on connecting mobile to LG Bridge, model shows as H901 but update shows as F600S30D :crying:
2. downloaded lg phone info app and saw the provider name as SK Telecom
i have attached three screenshots of my mobile phone. is this a genuine t mobile version ? what needs to be done to upgrade my phone to Nougat ??? instead of bricking my phone thought of taking your suggestion guys
thanx in advance
Do NOT use LG Bridge, or you will brick your phone. Dunno where you got your phone, but it has an F600 IMEI, so LG Bridge thinks you need F600 firmware.
There is a v20L KDZ floating around here somewhere. Grab it, and put your phone in download mode (pull the battery / put the battery back in / hold volume up / plug USB cable in -- you don't have to hit the power button). Once you are in download mode, you can flash the KDZ with LG UP. That will get you to MM 6.0.1 which is still rootable using the dirtycow method (if you care about rooting). If you don't care about rooting, I am uploading the v30b Nougat KDZ right now. It is not rootable with any currently known methods. If you do want root, root on v20L, and then I will also be posting an update.zip that will take you to v30b and keep root.

My goodness, thanks for the prompt reply buddy, you saved my @SS im seriously not worried for root or bootloader unlock. im ok with stock nougat without root. so which kdz i need to flash ? im confused
As far as I know, no one has uploaded the Nougat KDZ yet, so I am in the process of uploading it. Google drive is being REAL slow. Since you don't care about root, you can use the same method that I described above (get into download mode, and use LG UP to flash the KDZ). I will make a post just a soon as it finishes uploading.
You might want to take this time to be SURE that you don't want root, because once you flash Nougat, there will more than likely never be a way to root this phone unless another exploit in the Linux kernel can be found...

No if you update h90130b your phone will be a hardbrick.
You have to upgrade F600S30d But you might lose the network !!!
@SandyKick If you can return that phone for an exchange, you might want to. As @dodo73 said, (in not so many words) you are boned. You are going to have to take a risk either way, but the safest route since adb sees the device as an F600, is to flash the F600 firmware. If you lose network, you can then try flashing the H901 modem. Let us know how it goes, but you are probably going to have to do SOME kind of fixup -- it will not be a clean flash / upgrade / happy phone
EDIT: If you flash the F600 firmware and brick your phone, that is also easy to fix -- and you will know that you DO need the H901 firmware.

I dont think going straight from 5.1.1 to nougat is a good idea. And after 1 hr of download if lg up is going to say incorrect kdz then why time waste
@SandyKick first we have to upgrade it to 6.0 to see everything goes welll then decide to upgrade it to 7.0
I have been searching for v20L kdz link but which model it is the huge problem
as we can not flash H901 kdz.
f600L?
F600s?
F600K?
There are three model with several updates. :/ Pretty confusing right.

Hi guys,
I bough a used LG G5 back a couple of days because i have a lot of love for the LG G series. I got the phone after i had a quick look over the phone when i was with the seller and i was very happy about the external look of the phone so i bought it.
I had read that there is an official update for the LG G5 to Oreo so it was a big surprise when i realized that the one i got was still on 6.0.1. What i did was come back to the house, connect to the wifi and try to do a FOTA upgrade. No luck. It said that the phone was already at its latest update available. What i did then was to do a manual upgrade with LG Bridge. All went good and the phone was updated to 7.0. After the first reboot, i got the message "Current version is not available for user....". I didn't bother at the time because i thought that after a factory reset all would be ok. Well that didn't happen . I did notice something strange. The software version i had was referring to "EU" but now it says V20r-OPT2-SI. Perhaps the previous owner had the phone rooted and perhaps that version that it had was not the official EU.
Now the OS is full off bloatware and there isn't an update to Oreo available.
I want to:
- Find the appropriate OS version that my phone should have
- Get rid of the message that appears during the boot
- Get rid (if possible) from the bloatware when the correct OS is loaded
I want to use an official ROM with no root because of company regulations where i work so, rooting might be an issue. If i do have to root, i then have to unroot it again before use.
Because i have been away from the scene for a long time, please excuse my lack of information.
Regards,
If you don't mind loosing VoLTE support for the operators your rom was made for, just delete the /cust/ folder and you'll get rid of both error message and most of the bloatware.

That is indeed a nice tip that i was not aware of but would it be possible to know if i am able to flash a rom carrier independent in order to be able to upgrade afterward to the Oreo? If so, how can i find out the version that i can flash without damaging the phone?
Thanx for the help so far.
You can flash whatever rom you want (of course an H850 one, never try to flash a H830 or H860 ROM on the H850!!!). If you want to upgrade to Oreo having an Open EU stock rom, follow these instructions: https://forum.xda-developers.com/lg-g5/development/stock-h850-30a-eu-rom-flashable-zips-t3850072
If you follow colsely the instructions and charge the phone before proceeding, there's virtually no risk of damage (avoid flashing form a desktop pc in a stormy night, of course).

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.

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.

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?

Yup - just as you said. 20e restored Download Mode.

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!

Hello i wanna thank all of you guys for the amazing support on this device, he LG v30 is an amazing phone just bought a US99830B , downgraded it with LGUP to oreo, unlocked bootloader in oreo and installed TWRP downloaded 99830B flasheable zip and flashed it , then i waned to try lineage 17 and flashed it in TWRP clean install booted up in android 10 but noticed lots of bugs and no WIFI, flashed modem for oreo in TWRP wifi came back up but wanted to go back to PIE restored from a backup that performed for PIE and got botloop maybe because of the incompatible modem, tried download mode, no USB activity back to TWRP restored lineage OS and im back in the system, i took your advice to flash 99820b in TWRP my download mode is back and im on oreo, my question is if i KDZ 99830B from 99820b will download mode still work even tho it doesn't when i flash stock 99830b download mode gets lost, i dont want to flash the KDZ and end up with no download mode and no TWRP and have a hard brick
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.

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.
Thank you!

Completely uninstall LGUP and remove all folders of it. Then install the Dual Mode LGUP from ChazzMatt's H932 ROM thread linked below, using his exact installation steps. That's important: LGUP isn't just LGUP!

You don't say WHICH V30 you have. That's important information you left off. If cross flashed to another variant, what was the last stock firmware you used before installing custom ROM?
You can either:
* restore the TWRP backup you made before flashing the LOS- based custom ROM.
You did make a backup, right?
or
* flash TWRP-flashable zip (ROM) made from stock firmware.
Made for V30 with TRWP custom recovery by our Devs; basically stock ROM but with DTS 3D and other stuff already enabled. We have them for several V30 variants -- which is why we need to know what you have.
or
* use Dev Patched LGUP to install LG stock KDZ for your V30 variant.
Your Bootloader will still be unlocked. You will then need to follow WTF Section 6 Instructions to re-install TWRP, reformat internal memory, root. Unless you have T-Mobile H932, which uses different method to install TWRP. Which is why we need to know what variant you have.
(Saying you have a "V30" is like saying you have a "Dell" computer. It tells us very little.)

LG Bridge isn't going to work for you on LOS-based custom ROMs. It's LG software looking for LG stock firmware to update.

Thank you very much to those who have answered me, and tried most of the forms and just brick the cell phone, finally I read on a page that served to let much of the battery run out and try again and I did it and miracle It worked, I hope this helps another person with a similar problem.
