Hi guys I apologise for the noob question in advance but would really appreciate some help.

I bought a H931 not knowing it cannot be updated unless you are in the States. Unfortunately, the phone that I received, the data is not working currently.

So I presume I need to update but am not quite sure how to do so. I am on the original Nougat Sept 2017 version for the H931. How should I go about turning this into a US998 exactly? Can I flash with the LG UP (I believe) mentioned here to US998 Oreo straight away? What are the precautions prior to doing this? I've done lots of flashing in the past but am not familiar with all these new devices with locked bootloaders etc.

Thank you!

Look at the frankenstein thread. You should be able to use the patched LGUP to flash US998 20a oreo to your phone. Once you are on us998 20a, you can decide if you want to unlock your bootloader and root.

For the h931 which is at&t, this is a one way trip. AT&T does not release its kdz files.

I have a strange problem... I don't see the pop up box that the OP screenshot shows to select all when flashing Nougat US998. Currently seeing if I have this problem on other PCs too but if anyone knows why, I'd appreciate greatly.

For those having issues getting 20E installed with root, TWRP, and LTE on Sprint can try this:

1. Flash the 20E kdz with LGUP and Partition DL
2. Select All and leave all checked
3. Phone completes and reboots
4. Setup initially to enable USB debugging and PTP mode
5. Setup APN
6. Make phone call to voicemail
7. adb to bootloader
8. flash the newest TWRP currently
9. fastboot to boot TWRP
10. TWRP should decrypt files
11. flash magisk, no verity, rct disabler, and reboot system
12. You should now have 20E, TWRP, and root. Also at least 3G. If no 4G on reboot give it time and it will come in eventually. You can also restart once or twice if you like and/or call voicemail again. I make the call to verify connection to Sprint.

I did not flash the Sprint modem as I am testing to see if I get the delayed SMS issue using the US998 modem. I started having that issue again so I am doing more troubleshooting.

Also these are steps that should work coming from any rom and you are using an LS998 to start with.


edit: I have not had the delayed SMS since taking these steps a couple of days ago.


And this works for us Sprint people?

is there a link to help setting up APN and how to for Sprint?

Also, is this that much of an improvement from the Sprint 21a if it's running smoothly? The radio is the same I think we have discovered.

I used the screenshots in the OP post of the US998 to LS998 *Sprint LTE + Root* thread.

I am using the US998 modem not the Sprint modem this time. With the Sprint modem I get delayed SMS.

I am just thinking that if everything is fine on my Sprint 21a set up, there is no great reason to mess with it, right? 20E is still same I think

Well 20E has September's security patch. Also no real bloatware unless you count Google apps lol.

My problem was always getting LTE speeds that would work like they should outside of the Sprint stock rom. I briefly tried DotOs and it was working fine also. Plus if you make a backup of your current build you could restore it if you wanted.

How do you even know what LTE speeds your supposed to get?

With newer TWRP, no-verity-op-encrypt can be skipped in clean install... When installing Magisk and lg-rtcd-disabler, ADB 2.0/dm-verity is not preserved. This doesn't matter since dm-verity just checks if device is encrypted and prevents boot if not, right?
Thus device encrypted without the encryption boot check w/ Magisk installed.

Question I ran fastboot oem lock and now I'm bricked with "your device has failed a routine safety check and will not boot" Does anyone have the fix for this?

EDIT: Sorry, thought you meant you UNLOCKED it.

______
It's not bricked. That's just the stupid bootloader unlock warning. Give it five minutes to boot the first time.

After that will reboot in 30 seconds, but you'll still see the stupid warning graphic.

    For bootloader unlock purposes, use the US998 KDZ versions with pre-July 2018 security patch: I recommend 20a or 20b.
    Look at the names for dates in the title. You can always update to newer firmware later, AFTER bootloader is unlocked. Flashing a newer KDZ will not relock your bootloader. See bottom of post for instructions on how to downgrade to earlier firmware.

    ONLY USE MAGISK 18.X ON OREO TWRP-FLASHABLE ZIPS!

    If you are installing/updating latest US998 firmware for the first time after bootloader unlock/root, you should flash 20e zip (below), then 20f zip, 20g zip, 20h zip back-to-back in TWRP, then flash Magisk. If you go straight to 20h via TWRP-flashable zip from very early Oreo, you will most likely have problems. There were massive changes starting with US998 20f and you need the prior 20e as foundation before going on to 20h. You should also do this if coming from a custom ROM.

    Also flashing magisk in between each and rebooting in between each is not needed. You can add all (zips) to the queue and flash at once then flash magisk and then reboot. Tested this method with the us998 zips and works just fine

    Flash the "ROM" with latest TWRP, after wiping caches. Reflash Magisk immediately afterwards, before rebooting to system. It's just stock KDZ but in TWRP-flashable version. Not debloated nor meant to be updated in the future. It's just a very convenient mechanism to have newer stock firmware instead of using dev patched LGUP to flash partitions, etc. Go to this thread and thank him.

    Screenshots below are for previous firmware and only demonstrate how to upgrade full KDZ using LGUP.

    HOW TO (temporarily) DOWNGRADE BACK TO OREO FOR BOOTLOADER UNLOCK
    (or DOWNGRADE BECAUSE YOU DON'T LIKE PIE)

    1) DOWNLOAD FIRMWARE AND DEV PATCHED LGUP

    * Download Oreo KDZ you wish to install -- for bootloader unlock would be US998 20a or 20b. You can update to more current firmware AFTER unlocking bootloader on early Oreo.
    (If you just don't like Pie, then choose the most recent Oreo KDZ, which is US998 20h at the top.)

    * DOWNLOAD THIS DUAL VERSION OF DEV PATCHED LGUP, made by @tecknight:
    https://androidfilehost.com/?fid=11410963190603845019
    (Or use attached file from bottom of this post. Thanks to @tecknight! Please go here and click the THANK BUTTON!)

    _________________

    2) INSTALL DEV PATCHED LGUP

    0. Uninstall any prior LGUP you have. Uninstall anything like Uppercut, which no longer works and causes conflicts with this Dev Patched LGUP.

    1. Extract LGUP_DualMode.zip to a folder on your PC.

    2. Browse into the folder and launch LGUP_Store_Frame_Ver_1_14_3.msi.
    Follow the prompts to complete the install.

    3. In that folder, right click and select "Run as Administrator" on "SetDev.bat" to set LGUP to developer mode

    4. Launch LGUP using the desktop shortcut, NOT the Install folder shortcut.

    Choose Process : PARTITION DL (all partitions) or REFURBISH

    ----------------------------
    3) DOWNGRADING/UPGRADING ANY LG V30/V30+/V30S TO OREO KDZ FIRMWARE

    1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
    2) open patched LGUP and flash OREO KDZ to DL PARTITION mode. In the pop up box "Select All". Use the attached patched LGUP in this post.
    You can also use REFURBISH mode, if you wish.
    3) Master Reset (post 101 of Frankenstein thread)
    5) DONE.

    It's fairly easy. Most people breeze right through this. But if you have any problems, go through this list:

    • Make sure you in download mode BEFORE opening the patched LGUP file.
      This is at the top of the list as some people forget to do that. The remainder are in no particular order. If that doesn't work,
    • Try different USB port,
    • Try different USB cable,
    • Try different computer.
    • Reinstall LG mobile drivers on your PC.
    • Reinstall dev patched LGUP again, making sure the files are placed where they need to go (LG Electronics folder, etc).
    • REBOOT THE COMPUTER.

    If you ask for help, that's the list of items we are going to give you anyway. ;)

    WARNING: In LGUP do NOT go messing with modes not mentioned in these instructions. Especially do NOT use Chip Erase.

    3) ChipErase: Dangerous, This will erase IMEI/efs, Do not try this if you do not have a NV backup.

    No, not worth it. It's just September security update. We'll have November in a few days (probably), and TWRP flashable.

    Sent via open market LG US998 V30/V30+

    Yep im working on the us998 20E flashable now. Ive have it uploaded later tonight when i get off work. Ill also be taking over the kdz flashable zips for us and verizon from now
    9
    Added US99820b_03_0524 KDZ (2.76Gb)

    Right now with this full KDZ, if you are already bootloader unlocked and rooted, to update you need to flash via dev patched LGUP with DL Partition method -- but leave off "recovery" partition to keep TWRP custom recovery. Then in TWRP, reflash Magisk, the "no encryption" file and the "don't check root" file.

    If you don't do that, and flash the full KDZ, you will also have to reinstall TWRP.

    If we do get a TWRP flashable zip, I'll post the link here in this thread. Then you can just flash THAT in TWRP like a ROM... Until then you can NOT flash this with TWRP. Do NOT post messages that you cannot flash in TWRP. I'm telling you that already. ;)

    If you are not bootloader unlocked and rooted, then just flash via LGUP with "upgrade".

    ________
    @westwood24, can please make us a flashable zip of this KDZ please? You can make your own thread like you did with the H930 update and I'll link to it. Thank you!

    Tommorrow i will upload the rom
