Hey guys,
Does anyone know how we can get the rollback number on our devices? I was reading this thread here:
http://forum.xda-developers.com/g4/...wngrade-g4-t3197675/post62748057#post62748057
I guess you need to know your rollback number to do a KDZ becasue there is a chance of a hard brick. I tried the numbers highlighted below but it didn't work for Verizon. Anyone know how we could get this information?

This was not written anywhere specifically on the LG G4 forums that I could find. But every flash-addict needs to be warned. It is something you want to know before you continue tinkering.
Several users (myself included) have made the unfortunate mistake of attempting to downgrade their bootstack (for various reasons) to a former version.
DO NOT DO THIS (at least for the USA T-Mobile H811 version, and possibly other USA versions, per @autoprime)! It will result in a hard brick! Specifically, this results in the "Qualcomm QDLoader HS-USB port ( 9008 )" error. Connecting your phone to a PC will pop up with this active connection, but nothing else. There is no download mode. There is no publicly available fix as of yet.
This WILL happen both through KDZ restore as well as flashing bootstack .zips.
Yes, an official KDZ image can BRICK your USA phone, if you try to rollback.
This is in stark contrast to other manufacturers (i.e. Samsung), where the attempt to flash an older bootloader/modem/radio will simply fail, but your phone is not bricked.
I have conferred with @autoprime, who confirmed that with each OTA firmware release (on T-Mobile it was 10H, and now 10N), the version # increments. Flashing a lower version # will result in brick.
I have searched far and wide for a DIY fix. Without the proper firmwares in the right format, as well as the right flashing software, your phone is done and must be sent in for LG repair.
To check what antiroll-back version you are on, input this sequence in the dialer (T-Mobile and ATT) and scroll down:
*#*#244773825625#*#*
Flashing a bootstack version less than this # (through KDZ or zip) will brick the phone. You are free to flash anything equal or higher than the version listed.

If you are still on the original software version 10b, then you have v0. If you took the OTA (or flashed the KDZ) to 11a, then you have v1.
We have a new OTA out now, 12a. I'm not sure what version that one is, but I'm willing to bet it is v2, and you will not be able to rollback if you install it.

Yeah right now I'm stuck with 11A and I'm not sure what I should do. Even though my phone sucks the way it runs, I'm gonna hang in there and wait a couple weeks. See what comes out of 12A.
Well I don't believe there is a way to check or there is a known way of finding it yet. Apparently there is an APK app that reads it. Perhaps we can rip it from another rom and access the APK via the same method we do for accessing the Themes (using a launcher to do custom shortcuts).
The inability to KDZ back to original software is ridiculous. Just like 12A and the broken notifications. How stupid is it to force broken updates yet make it impossible to go back to previous backup/software. I am half tempted to just take the 12A update and force Verizon to give me another phone just to emphasize my dislike for their method of locking the system down.
Hello XDA,
I got an LG G4 gifted, and as one of the first things I want to do is to root it. However I seem to have quite some difficulties with it.
My previous phone was a Nexus 4, and I simply rooted with 'Nexus Root Toolkit'.
For this phone there appears to be many, different ways to do that.
First thing I need to be sure is what exact model my G4 is.
In 'Phone Info > Hardware' it simply says H815. In the LG Mobile Support Tool it says H815B (Which gives no result on Google). The phone is from Germany if it helps.
Second thing is that it says I can update to SW version v10c. But when I download the update, it simply throws a 'Invalid Software Package' error at the end of it. The LG Mobile Support Tool says I have no update avalaible instead.
Third thing is that I don't remember if I have to unlock the bootloader to root my phone (did that only once on my N4, forgot if it's needed). If yes, can somebody link me to the appropriate page? (I've read around LG itself released a tool to unlock that?) (Also, I will loose all my data IIRC?)
Last thing, obviously, the most appropriate Root guide for my model. I've read many of them, one requires you to have linux on your PC (Which is a nope), others mentions '10c' (which I suppose is the update I'm unable to get). So far I got myself only very confused. (Root voids warranty? IIRC LG still covers phone with root?)
Thanks in advanced for your help
EDIT: Currently trying with LG Bridge software, seems to work and says my phone is H81520A (So I suppose the part after the device code is the 'SW Version' ?).
EDIT2: Apparently updating with that software worked. Now on v10c (Marshmallow 6.0 - Unless there are other updates waiting)
You can indentify your model by adding your IMEI to the following link: csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
(look for the field buyer)
The unlock process is described in this thread.
But don't fash SuperSu If you are on Android 6.0, because it will fail to boot. First flash an custom kernel (like this) and then SuperSu.
If you're unable to unlock the bootloader, then there is no possibilty to get root on Android 6.0.
Thanks. It says DEU at the buyer line.
D(eutschland)EU(Europe) I suppose.
And thanks for the link. In the kernel page it says 'download 20a or 20b? What's that number? So I need a Kernel that inclused SuperSU as flashing it on its own will cause that problem in few words?
What about this? http://forum.xda-developers.com/g4/development/repack-kernel-root-android-6-0-t3232387
From what it seems, it's a custom kernel + root. Would I still need to unlock the bootloader? Perhaps using the 'LG Site' section from the thread you linked (http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241)?
The software versions are quite strange on lg phones. 20A was the first test version that was released in poland. The official version now is 20B but phones with a branding have different versions. For example my phone has a vodafone branding and has the version 20A, but it is the same as unbranded 20B. (so it's really strange some times)
Look what is written in the settings under software information.
You need to unlock your bootloader to root your phone on Android 6.0 (this will void your warranty). You're right, it seems that SuperSu is already integrated in the kernel so you don't have flash SuperSu separately. But i am not complete sure because i didn't unlock my bootloader.
Thanks a lot for your help.
I managed to unlock the bootloader, but then I fuffed up..
Accidentally installed SuperSU (Was following that guide, and forgot about what you said).
Now the phone is kinda stuck at the very start, with the LG Logo (Not the animated one, the very first one)...
I'm hopeless now? D:
EDIT
I'm trying to recover with this video (LG G4 KDZ Firmware Restore Unbrick and unroot tutorial -- can't post links yet..)
But the LGFlashTool throws an error at 9% (imgur link -- can't post them fully yet) imgurDOTcom/pR1NYHD
EDIT2
Apparently I'm trying to flash a KDZ with Android 5.x while I'm on 6.0, which is a no. Will try with a 6.0 KDZ if I find one...
Else I hope for LG assistance (Or Amazon support, since the phone is less than 1 week old)
EDIT3
No luck with KDZ, but now the phone is going past to the animated logo, but being stuck there..
EDIT4
This saved me: http://forum.xda-developers.com/showpost.php?p=63843511&postcount=146
Worked perfectly, my phone is back and fully working
Sorry, i wasn't online the last couple of hours, but i'm glad that all worked out for you

No problem, you were of great help.
I'm currently not trying to root until there is a safe procedure to do so for 6.0
I don't think that there will be an easier option in the near future. You can make a backup with twrp and try to flash the kernel again.
Mmm, currently I have only the bootloader unlocked. No root, no custom recovery.
I don't feel like to play more with these stuff in the near future, after I nearly bricked the G4
Perhaps later on.

My apologies if I misunderstood. Is this a way to apply alternative ROMs even on models with locked bootloaders and the ADB Commands stripped out such as the H 933? I know you said already that it will work on any variant but I had lost hope that this model would ever allow modding of the rum. I just want to make sure I'm not misunderstanding the intention of your guide.

Out of interest, will this work on a rooted V30. I seem to struggle to get LGUP to boot my phone into download mode. Is it because I have twrp as recovery?

It will work as long as your /laf partition is in tact. It containts the DL mode. It has nothing to do with /recovery partition where you most likely flashed TWRP.

Just so I don't brick my device, I have an H930DS, therefore any firmware marked for this model (https://lg-firmwares.com/lg-h930ds-firmwares/), regardless of region, would work on my phone? My phone is currently on HK region version, can I flash the Indian firmware for the same model?

I have no idea about cross region firmware flashing. I have not found any official documentation about how each of LG UP's functions exactly works, it's all user experience here on XDA. Supposedly, every region has firmware signed with different RSA key which is verified upon trying to flash and it will reject you if it's a mismatch. Also I doubt Indian region has the same bands as HK so you might cripple your mobile signal if you happen to be on a band that is not supported in Indian firmware. Personally I don't recommend trying it but its up to you Please share your experience if you do
I know for sure that all H930 sold in EU, regardless of what carrier can be flashed with the same H930 unbranded EU firmware, which removes all carrier bloat and branding.
@sasc Check the RSA signature of your firmware and compare it to the firmware you want to flash. If they match, then it won't brick your phone. Your phone may not work, but at least your will have access to DL mode. If they don't match, you will definitely brick your phone..

India and HK are both global GSM regions. The bands are the same, just like Europe.

Okay.. I bring good news! You can definitely flash any KDZ as long as the model number is exactly the same. I flashed the HK Reginal kdz on my H930DS from India and I now have working VoLTE and VoWiFi.
In short, get the CORRECT kdz of the desired region for your model number, use LGUP, Upgrade option, and let it do its thing. Simple. This keeps the device official and under warranty.
PS - Please backup all data before doing this. Even though it is just an upgrade, play it safe. Just in case!

So...kind of didn't work.
I used the H930DS marked India in lgfirmwares. The flashing process went fine, except for the phone getting stuck right after the last restart and the screen went blank. Waited a couple of mins and forced a restart using the power button..booted fine but all data was gone. Thankfully i did backup some stuff, but not all..
Checked the Software version, it says V11i-GLOBAL-COM, which is obviously not the India version. And, I still dont have Volte!! So, this was futile..
Can anyone point me to a certified H930DS India KDZ?
So I've just recovered my phone from my 1st attempt at updating to Pie on my unlocked AT&T v35.
But I'm left wondering if the process for updating from Oreo to Pie is somehow different than when I successfully updated from Marshmallow to Oreo.
The process I thought was:
1. Put phone in download mode
2. Connect phone to pc
3. Run the Modified version of LGUP
4. Select your ULM KDZ choice (any of the three will do)
5. Select Upgrade
6. Flash phone
Are any of these steps incorrect and should step 5 be Refurbish instead of Upgrade?

I used upgrade, when going from ULM 8.0 to ULM 9.0. I would assume you would use refurbish if going from stock to another firmware. Of course assumptions aren't really reliable.
I've been trying to figure out if I should do UPGRADE or REFURBISH as well.
I found this: https://forum.xda-developers.com/lg-v30/how-to/guide-how-to-upgrade-downgrade-restore-t3738917
Says REFURBISH wipes user data, UPGRADE does not. If moving from one image say from AT&T, to the Unlocked firmware I'd assume you want REFURBISH.
So since I used refurbish to go to the ulm software from 7 to 8, do I still need to refurbish going to any of the ulm pie variants?

That's what threw me for a loop on my first attempt. Since I'd successfully upgrade from the AT&T 7.0 firmware to I believe the Amazon 8.0 ULM firmware without issues, I thought the process would be the same going to 9.0. But I ran the upgrade through LGUP which was the modified version, and it crashed at 74% and sent me down a wonderful rabbits hole of brickage.

I don't understand how were you on Marshmallow before flashing to Oreo. I'm pretty sure the the V35 launched on Oreo 8.0. But I'm also looking for a way to get from Oreo to Pie on ULM kdz.
I went from AWM12k to ULM10i choosing REFURB and all went well (I followed xatokk's post on the lgV35 subreddit).
When I try to get from ULM10i to ULM20d (Pie .kdz) I guess I only have to drag ULM20d kdz in LGUP window?
I just want to make sure that's not how you bricked your phone before I try REFURB from ULM10i to ULM20d
Any advice would help, I'm a noob at this.
FWIW, partition DL worked fine going first from AT&T firmware to Oreo ULM and then again to Pie. Sadly I had to set up the phone again.

Sorry, Brainfart, I was completely out to lunch on that. I wanted to flash the latest available security update, but since I'm in Canada I could never get that from AT&T so I had to find a way to flash it and that led me to XDA and the whole LGUP process. So you were correct on that, and I did flash the Amazon 8.0 KDZ I believe without issue.
My brick happened when using the Amazon pie KDZ and using the same Upgrade process in LGUP. The update got to 74% and then crashed. I then tried to run the refurbish option but that crashed as well so by that time, my phone was beyond my knowledge of how to fix it

Partition DL was not available in the process list of the modded version of LGUP I used. Which one did you use? I think I found the right one.
Now, selecting PARTITION DL, do I need to select all like mentioned in the Frankenstein Phone thread for the V30?

This phone launched with Oreo and had nothing prior. He's mistaken, confusing some other model.
That's what I did.
The error you experience may be due to a usb cable. a particular usb port on your computer, other software on your computer, and maybe bios settings. The v30 WTF and Frankenphone forums would be good places for background and solutions.
Fingers crossed for a successful flash.

Here's what I did if you don't already found a way. I also faced an error trying to flash to Pie ULM.kdz.
I don't know why but LGUP for developer patched from 9to5lg.com didn't work for me. I tried PARTITION DL it crashed at 91% and I also had to reboot my PC. I kept the phone plugged and reinstalled LGUP.
My V35 was on AWM12k when I got it. I followed xatokk's post on the lgV35 subreddit to get it to to ULM10i choosing REFURB.
I kept the same .dll I extracted from to ULM10i and I did a REFURB to ULM20d .kdz just dragging it to LGUP.
I hope this can help you.
To update my earlier reply on this topic. Somehow flashing REFURBISH from AT&T stock Oreo to ULM(Unlocked) Pie it failed and bricked my phone. As mentioned in another thread regarding unlocking the bootloader and root, I had to call on @motogvasyag to not only unbrick my phone remotely but he also unlocked the bootloader and rooted it. If anyone has any issues with bricking you might want to contact him. He's fast and does amazing work. I only mention this because I am very appreciative of him and his work. I'm not sure why my flashing failed at around 70 something percent but I'm glad to have my phone working again along with the update to pie and root.

To update my earlier reply on this topic. Somehow flashing REFURBISH from AT&T stock Oreo to ULM(Unlocked) Pie it failed and bricked my phone. As mentioned in another thread regarding unlocking the bootloader and root, I had to call on @motogvasyag to not only unbrick my phone remotely but he also unlocked the bootloader and rooted it. If anyone has any issues with bricking you might want to contact him. He's fast and does amazing work. I only mention this because I am very appreciative of him and his work. I'm not sure why my flashing failed at around 70 something percent but I'm glad to have my phone working again along with the update to pie and root.

@motogvasyag unbricked my AT&T V35 that was stuck in fastboot from a failed flash. Took care of it right away. Phone is now factory LG on Google Fi, Pie, wifi calling and all three carriers. Highly recommended!
I have LG G8 Alexa variant. Model LM-G820QM.
I think ts on latest firmware "qm21e". Right now I live in India so the VoLTE is not working. I tried to cross-flash it to Open firmware but LGUP gave error "Cant change the device(AMZ_US > OPEN_US)".
I have three questions.
Can I cross flash Korean firmware ?
And if so, will i get VoLTE working ?
And my G8 has 2 cams while the Korean varient has 3 cams. Will my cams work with Korean firmware ?
Thank you.
Do you by any chance still have the OPEN_US Firmware?
I've been looking everywhere for it but I can't find it.

Thanks for your reply
Unfortunately, neither one worked.
I tried the first one, however the flash tool didn't work because (OPEN_US_>NAO_US)
The second one would not download at all. I don't think it would have worked anyway since my phone is not the Alexa version. It's factory unlocked, purchased from Best Buy.
Hey man, I was able to figure out my problem! Not only that, I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root!
I appreciate your help, and I want to help you if I can.
As for the cross-flashing, you can't do it via LGUP. The only possible way is to download the firehose for your phone and to use the Qualcomm Image Flash Loader(QIFL) tool. You can extract the firmware you want to flash, and load all the images into the QIFL partition manager. There is no guarantee your phone will boot from it, but you can try it. NOTE: Do NOT modify the OP partitions! This will cause your phone to throw an OPID mismatch error and it won't boot!
As for the cameras, you may be able to extract the current Camera APK from your phone and install that on the Korean firmware so that you are still able to use them. No guarantee this will work, and they might work fine with the Korean camera APK, but it's worth doing before you flash.

I see, but I just want VoLTE to work. I don't mind using stock rom or custom rom too. So keeping that in mind what do you suggest? And also, Do you think that your solution " I discovered one of the NAO_US Firmwares was actually OPEN_US, and that worked for my phone. I am now back up and running, with an unlocked bootloader and Root! " could work for me too ? If so do let me know how did you figured that NAO_US was actually OPEN_US. Maybe I can find out one for AMZ_US.
On the box Model : G820QM
SKU : G820QM8 (QM8 stands for AMZ)
Thank you.
I'm really not sure how VoLTE works internally, so I couldn't tell you if using another firmware would actually work for you - but the way I found out one of the firmwares was actually OPEN_US was by extracting it using the KMZ extractor tool someone made. This is how I was able to reflash the partition on my phone that I screwed up on in the first place and created a brick with. Like I said, you could manually reflash all those partitions one-by-one in QFIL, but i don't recommend it as it may not even work and could potentially brick your device. It's really up to you in this case, if you'd like to try though:
Download the firmware you want to try, search for KZM extractor on Google, download QFIL and all of it's prerequisites, and finally the firehose.
Use the KZM extractor and place the firmware inside of it.
Once it is done extracting all the files, put your phone into download mode and open QFIL
NOTE: DO NOT FLASH THE PARTITIONS WITH 'OP' IN THEM! Your phone won't boot for sure!
From QFIL use the firehose file and manually, one by one, sort through the output files of the KZM extractor and find the partitions that match their name and flash them with the file.
Zero guarantees this will work, and you may end up with a brick for a phone at the end of the day, but if you're that desperate it just might work.
Hi there.
I am still looking for solutions for VoLTE to work. I googled a lot and came on this post " https://piunikaweb.com/2021/06/07/unlocked-lg-g8-thinq-now-supports-att-volte-after-april-update/ "
Mine is Amazon version "QM8". Yet I did received april update via OTA. But still no VoLTE. I can OEM unlock from devs. Can I flash AT&T "QM7" on Amazon "QM8" ?
What do you think of this please let me know.
Thank you
VoLTE seems to depend on files in the OP partition, so crossflashing other partitions but not OP will not get VoLTE to work. LGUP will not allow crossflashing.
See my experience to get working VoLTE and Wifi Calling: https://forum.xda-developers.com/t/lg-g8-volte-fix.4113291/post-85455109
You will need to be bootloader unlocked and rooted.
