Hello friend. I recently updated my 930ds indian lg v30+ to pie and i want to rollback to stock oreo. I did try your method with v20a and v20b.. However, i get the error always that please use the latest dll file.

I tried reinstalling. Different different ways but no solution till now.

Can you recommend me something please.

I appreciate your time.

Thank you.

You need to use the newer Dev Patched LGUP from the Pie thread and uninstall any prior version.

Hy All, When I am applyig for bootloader unlock code I am getting below system message. Do you think that I still can open my bootloader somehow?

Are we able to downgrade from Oreo to Nougat ?

Will wait for anyone advice :)
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Singapore is the "SEA" region for LG.

Here's your Singapore Pie KDZ (30c):

https://lg-firmwares.com/downloads-file/20706/H930DS30c_00_OPEN_SG_DS_OP_0903

Here's the last Singapore Oreo KDZ (20f):

https://lg-firmwares.com/downloads-file/19632/H930DS20f_00_OPEN_SG_DS_OP_0425

You can also flash EU H930 KDZ over any H930DS, and it is compatible. But if there are regional carrier features you need (like some carriers' VoLTE), you may not have that with the EU H930 firmware.

You can downgrade from Oreo to Nougat, but why would you want to? Oreo is much more polished than Nougat -- has less bugs, and also more features. In the latter Oreo releases, LG improved the front and rear camera, also improved anti-burn in, AND gave DTS Surround Sound stereo (but you still need root for that). That's why we tell people not to even remain on early Oreo, much less very old Nougat.

The best firmware for this phone is the last Oreo KDZ.

No OS installed

Hi,

After flashing the twrp flashable zip when trying to reboot I get a message "No Os is installed. Do you want to reboot anyway".

What am I doing wrong?

Flashing magisk immediately after rom zip and then rebooting will solve this issue?

Thanks for help.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
The instructions say to re-flash Magisk before rebooting. Why are you asking if you should do that?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] pvramk:
Thanks for your reply.

Didn't want root. Wanted an unrooted system. Hence didn't want to flash magisk. Should have worded my question better.

Is reflashing magisk the only option? Don't want to go the kdz way either.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
If you don't want root, then you need to re-lock your bootloader and flash the KDZ via Dev Patched LGUP.

(I really don't care if you don't want to flash the KDZ. You're not reading and following instructions.)

But until you root your phone you won't have DTS 3D Surround Sound stereo. This TWRP flashable zip has it enabled.

If you flash the TWRP flashable zip (ROM) and Magisk and still get that error message that there's no OS, then something is wrong.

You may need to reformat your internal memory. Or you can try rebooting to TWRP from within TWRP, and try re-flashing the TWRP flashable zip + Magisk.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] tech_infinity:
Why do you not want to flash magisk? It makes no sense.

If you don't flash magisk, because you've an unlocked bootloader safetynet will fail and many apps won't work.

But magisk with magisk hide will solve this issue.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] pvramk:
Thanks again for your reply. will try flashing zip + magisk later on.

You still may get that error message. That's why there are the dozen WTF Section 7 Trouble Shooting Tips. Only the first is about being on the correct firmware. The other 11 are to help the phone communicated with the PC in fastboot. Different cable, different ADB installation, different port, different computer. It finally works for everyone, just easier for some than others. Intel Windows 7 with USB 2.0 ports are the easiest. Windows 10 can work but sometimes people need to buy cheap USB 2.0 hub.

Indian H930DS

I'm at software version V20b and security patch - august '18[Screenshot attached]. Do I still need to flash the downgrade KDZ to be able to unlock the bootloader and root ?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ravi_blade:
Do we need to flash magisk after flashing this KDZ

I am using an Indian H930DS and flashed an EU kdz for Oreo previously and unlocked bootloader and rooted it using the WTF! method. The security patch level is at march-18. Now, if i try to flash the kdz from the OP (the Indian one) using the upgrade method,

I have few queries:

1) Will I be keeping the root access or do I need to be flashing magisk again?

2) I froze many packages using Titanium Backup Pro(thanks to root access).If I lose the root access after flashing this KDZ, will there be any issue due to the previously frozen packages?

3) Call recording function will be overwritten with the stock-LGIncallUI.apk?

Sorry for the long post. Any pointers will be appreciated.

Software version: https://ibb.co/27SPBXy
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] mehra1:
1st. Install magisk after installing the rom zip before even booting it for the first time. In order to keep root.

2. As the rom is complete, u have to froze all the packages again. Only if u have the root.

3. Yes call recording will also be overwritten...

None of the above is bad or difficult to re do it.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Not just Magisk but also the no encryption, no root check files.

You do have TWRP still (if you're Unchecking recovery partitions), but you have stock firmware and need to flash all three files.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Maybe flash ESA again using DL Partition mode. Sounds like something didn't install correctly, even though it said it was completed...
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Read the first sentence in post #1. It's the security patch that is the issue, not the firmware "letter" which LG has been inconsistent about. You need Oreo with pre-July 2018 security patch.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jhung:
I forgot to tell you that I downloaded my ESA firmware at lg-firmwares.com. Is it the same fw as the one you posted here? I'm going to try now the DL Partition Mode. Do I need to uninstall first the LGUP software I installed? I'm not using the modified LGUP.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Yes, it's the same one. Just easier to download here since you don't have to through the silly captcha challenges.

Best to use the dev patched LGUP. I'm not sure the "regular" LGUP has DL Partition mode. You don't need to uninstall the other, just replace the files with the patched ones. In the instructions below you would not be creating folder since one exists already. Just replace the existing files with the patched files from the zipped folder.

Here's how to install the dev patched LGUP:
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jhung:
Ok got it. Thanks.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jhung:
Done flashing DL Partition mode. My phone stucked again at bootup screen. Is this normal? I'm just going to do a Master Reset and I think it will boot normal afterwards. My concern is that why is that happening to my phone when I sometimes do flashing? Sometimes it will boot normally sometimes you have to do Master Reset.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
You are sure it is stuck? Sometimes takes a few minutes for first boot. How long has it been "stuck"? One time I did it and it took 10 minutes. Don't know why.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jhung:
Sweet! Problem solved. Thanks Chazzmatt for helping me out. ?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] jhung:
I waited for like 5 minutes and It's kinda long for me coz in my previous flashing the bootup wont take long. Yesterday when I reflashed it I waited longer but nothing happened. You think It's fine I'd rebooted the phone and did Master Reset instead?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Well, you got your data indicator and arrows back. So, let's just assume everything is OK. You are also on the the "right" region KDZ for Philippines, ESA.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] Zoki88:
So if I understood, I have to flash Indian KDZ, especially 20b version (INDIA H930DS20b_00_OPEN_ESA_DS_OP_0530.kdz) on my V30 which have Hong Kong KDZ, after that I can, for example, using some tools on PC, get root and supersu on phone that easy, like on my old lg g2, right? And I can update (flash) newer KDZ without worrying to delete root, supersu, twrp, unlocked bootloader?(and that update doesn't need to be Indian version to keep all that? I can freely flash any region KDZ with keeping root?). And one more question (didn't find that anyone asked this one): can I downgrade to Nougat (KDZ with version 10, 11a,b,c... whatever it is) and keep root just like keeping it when upgrade? And same question with this one: that downgrade doesn't need to be Indian KDZ to keep root, it can be any region, for example, returning to Hong Kong? I know that it's maybe crazy for some people why I asking for downgrading, but I read on some forums that battery life of V30 is worse with Oreo than Nougat, I guess because of that AI and ThinQ stuff... All answers will appreciate :D
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
For H930DS, you don't specifically need INDIA (ESA region) KDZ for bootloader unlock and root. You can use any region H930DS KDZ -- or even H930 KDZ, as long as it's pre-July 2018 Oreo firmware (which is easy to install/downgrade to via Dev Patched LGUP). After every question you keep asking if you can go to some other region KDZ -- so you must not want India (ESA) region firmware. Whereas, India users needs ESA region if they want India carrier Jio VoLTE.

You seem to want Hong Kong KDZ, so you can start with

a pre-July 2018 Hong Kong KDZ

, like I have posted at that link.

For V30/V30+/V30S bootloader unlock, TRWP, root You simply need

fastboot flash commands and

(temporarily) pre-July 2018 Oreo firmware for the WTF bootloader unlock exploit.

All H930DS phones already have fastboot flash commands. After that, you need pre-July 2018 Oreo firmware -- at least temporarily. You can use dev patched LGUP to flash to the pre-July 208 firmware of your choice. Use the

WTF Instructions to unlock your bootloader, install TWRP and root.

After those steps, then you can update to newest firmware, or yes downgrade to Nougat -- using dev patched LGUP attached to post #1 of this thread -- and still keep the bootloader unlock and TWRP. Every time you flash different firmware you will lose root -- BUT if you take steps to keep TWRP custom recovery, you just reflash Magisk (along with two other files). If you use a TWRP flashable "ROM" zip file, its even easier -- all you need to do is reflash Magisk.

If you lose TWRP custom recovery when flashing different KDZ, then you have to use fastboot flash commands to re-install it. It's not hard to do, and your bootloader is still unlocked -- but it's wasting time re-doing something you've already done before. So, be careful when flashing the different firmware after you've installed TWRP. You want to DL Partition mode, but UNcheck the "recovery partions" to save TWRP custom recovery.

All your questions are answered in the

WTF bootloader unlock instructions

. Read those Instructions and then if you have additional questions, ask in that thread.

[Variant: India H930DS]

Alright so I used the patched LGUP to flash the pre-july kdz and then unlocked bootloader, flashed twrp and got los running. But I had to get back to stock since my earphones stopped working and for some reason the guys at LG center wanted to check my phone before replacing the earphones. Anyway so I used LGUP to get back to complete stock and relocked my bootloader. Can I expect OTA updates now or is using LGUP the only option to upgrade ?
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Probably LGUP, but I'm not completely sure about that. Right now there's no update to test with.

Am in Havoc os ( H930DS IND), how can i go back to stock. But i need bootloader let unlocked. Help pls.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
Dev Patched LGUP with Partition DL mode. Flash stock KDZ, but UNcheck recovery partitions to keep TWRP custom recovery. You'll have to flash the no root checker, no encryption files + Magisk again, like when you first rooted.

Bootloader lock/unlock has nothing to do with flashing firmware. It stays locked/unlocked until you flash fastboot lock/unlock command.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] bgshankars:

[LG V30 ROMs, Kernels, Recoveries, & Other Developm] drone991:
I previously used your linked version(IDN ) of pre-july kdz to downgrade. Now If I were to use the IND variant of the latest kdz(0808) to upgrade, would I need to do a master reset ?

PS: I know there's hardly any difference between the two but since I have Indian H930DS I'd rather just upgrade to the IND variant if I don't have to reset the data.

I'm on complete stock.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] ChazzMatt:
If you are complete stock without TWRP custom recovery then you can simply use Dev Patched LGUP in "upgrade" mode to flash the latest KDZ. You will not lose any data. Make sure you choose "upgrade" as the default "refurbish" will completely wipe your phone.
[LG V30 ROMs, Kernels, Recoveries, & Other Developm] bgshankars:
Yes i have followed the steps and flashed successfully. Thanks for the steps.
