Download patched LG UP

Download US996 10p KDZ

Place your phone into download mode. With the phone off, hold vol up and plug in the USB cable.

In LG UP, use the DUMP option and select modemst1, modemst2, persist, persistent and misc

Then while still in LG UP, use partition DL mode, select the US996 KDZ, select all partitions, and flash.

Enjoy your H910 converted to a US996.

If you have data or voice problems after the conversion, then you will have to root to fix it. You can't root on 10p firmware, so you will have to flash older firmware. Even though you will have flashed the US996 firmware, you can use the H910 root procedure here. Once you are rooted, you can flash a US996 stock ROM via TWRP to return to stock US996 (with or without keeping root -- tis up to you).

Once rooted, you can flash modemst1 and modemst2 (ignore the others, it is just a good idea to have backups of them) that you backed up in step 3.

Boot to flastboot. With the phone off, hold vol down and plug in the USB cable

fastboot flash C:\path\to\modemst1 modemst1

fastboot flash C:\path\to\modmst2 modemst2

Again, those steps will ONLY be required if for some reason you get unlucky and your EFS gets hosed.

[LG V20 Questions & Answers] AWT86:
Thank you, your post is the first one I found that makes it seem fairly simple.

I have 2 V20 h910s I want to unbrand, one running AT&T version 10m and one running 10r (which complicates matters further), and I would like to avoid installing a bootloader/root/etc. which prevents future updates/upgrades to later software versions (so other existing guides have put me off for multiple reasons).

Is what you listed all I need to do (in both cases), or do I need to root (or bootloader unlock etc.) first?

Can I install any future stock US996 ROMs (ie when Oreo is released) once I have done this, or will I have to reverse the steps and start over with h910/ATT software?
[LG V20 Questions & Answers] dark_prince:
Edit: Brain explained to you rather more profoundly. I rest my case of explaining it further :D
[LG V20 Questions & Answers] AWT86:
Hi.

I also have a few questions (as I'm new to this and have found conflicting information, and in addition I have two h910 phones running different firmware versions, one v10m and one v10r).

1) My phone's aren't rooted - Is what Brian explained all I need to do, or does his explanation require a bootloader-unlocked/rooted phone to work?

2) Are there any requirements/restrictions (eg. original firmware must be above/below version XYZ - if yes, does it make any sense to update the firmware to the latest AT&T version first)? Can I install any future versions of US996 KDZ that way too?

Thanks in advance.
[LG V20 Questions & Answers] dark_prince:
1. For 10m one, follow Brian's guide, for v10r, follow Brian's guide. Once you have unlocked bootloader/rooted, you have conceded official updates. Also there are no stock KDZ restoring methods to revert back to H910 but you can try a method to go bone-stock H910 if you're rooted and have TWRP recovery.

2. For H910? no, and no need to upgrade to latest att firmware. You can just jump the gun to US996 ;)

Edit: Make sure you take full backup dump with patched LGUP (from Brian's guide as well).
[LG V20 Questions & Answers] AWT86:
Thanks

Thanks a lot.

Two final questions (sorry to bother you):

1) Do I need to root/bootloader-unlock the device BEFORE proceeding to use Brian's guide, or can I just dump & then flash US996 straight away without rooting? (I read somewhere that root is only required if the signals fail after US996 conversion, but I'd rather ask than to skip root / just flash and then realize I messed up).

2) Will EFS be backed up in the process of dumping everything using patched LGUP, or do I need to back up EFS manually/seperately? If the latter is what I need to do, what is the best method? (I've found multiple, but most of them require root, which I'd rather avoid unless necessary)
[LG V20 Questions & Answers] dark_prince:
1. Make a backup dump and flash US996 rom.

2. I havent known anyone who ran into corrupted EFS after crossflashing between H910/H915/US996. The restoring of modemst1,modemst2,modem, misc solves the problem of No baseband/IMEI. Do that at your own risk, there is no guarantee that you'll be safe from apocalypse :P
[LG V20 Questions & Answers] runningnak3d:
You do not have to root, just follow my post for flashing the US996 KDZ.

You only have to root IF you have signal issues, because that is the only way to fix them. Even then, you don't have to stay rooted.

I doubt you will have signal issues, but make sure you backup those partitions before you flash the US996 KDZ.

[LG V20 Questions & Answers] AWT86:
Hi.

I'm having trouble with LGUP. When I try to dump all phone files, it gives me an error 0x2000 saying "not enough hard disk space", even though there should be more than enough.

Device Manager recognizes the device under Ports as "LGE AndroidNet USB Serial Port (COM8).

Help would be highly appreciated.

Thanks in advance.

EDIT: I managed to dump the files you recommended, but what about the rest? shouldn't I back those up too?

---------- Post added at 11:51 AM ---------- Previous post was at 11:24 AM ----------

UPDATE: I flashed the first device, but it asked for a password that wasn't set up. UPDATE 2: solved w/ factory reset.

Thanks a lot and sorry for bothering you guys.
[LG V20 Questions & Answers] runningnak3d:
Glad you were able to do it.

As far as backing the other files up -- no, you can get those from a KDZ, so no reason to back them up. The partitions I had you backup are specific to your phone(s).

-- Brian
[LG V20 Questions & Answers] AWT86:
Now flashed both devices, but noticed that the signals are unstable. Network jumps randomly from no network to 4G and back to no network etc - not in high frequency, but often enough for me to have noticed.

Does that mean I now have to go the route of rooting or is there anything else I can try?

Thanks and sorry to bother you once more.

PS: just noticed it seems to run stable with only 3G enabled, but once 4G is enabled the problem starts.
[LG V20 Questions & Answers] runningnak3d:
That isn't an EFS issue, if it was, you would have no signal.

Your carrier probably is using bands that aren't enabled on the US996 but are on the H910. There are several threads around here on how to check what bands are enabled, and how to enable bands that aren't.

If you can't with the US996 modem, then yes, you will have to root to flash the H910 modem back onto your phone since there is no H910 KDZ.

If the modem IS the problem, once you are rooted, and flashed the H910 modem, you can unroot keeping the US996 firmware except for the modem. It is a long, boring process though :)

EDIT: also, if you ever take an OTA update, the modem will get replaced and you will have to root to replace it. If it is no longer possible to root, then you would be stuck.

I don't advise people to run cross flashed models that aren't rooted, and take OTA updates -- there are just too many risks....

My advice to you would be to root, and then flash the US996 version of Alpha ROM. You don't even have to stay "rooted". You can uninstall Magisk, and just keep the eng. bootloader, and TWRP in case you need to fix your phone. When an update comes out, you can just flash it with TWRP instead of taking an OTA.

EDIT 2: You can try the H915 modem. Grab the latest H915 KDZ that is available, and use partition DL in LG UP and pick just the modem.

Hi Brian,

Thank you for the guidelines. I have LG V20 h910pr. Followed the above procedure. ROM updated successfully i.e. US99610p. Call quality is OK. For Data following are my observations:

1- Previously I had to dial code (*#546368#*910#) to enable 4G mode. But now it's already in 4G. Showing Global Mode and LTE in Network mode.

2- Wi-Fi Tethering was not working previously but now it's working fine.

3- 4G is working fine with Facebook, LinkedIn etc. but when I open Chrome or Edge browser it doesn't work. Any work arround on this will be highly appreciated.

Thanks again

[LG V20 Questions & Answers] AWT86:
Bands are ok, my carrier only uses GSM LTE Bands 3 and 7.

Will proceed now to flash the old firmware & install TWRP, then root, then flash current US996 and Modem files (obviously, those named "modemst1 & modemst2"). Is this the correct order in which to proceed?

UPDATE: the phone now enters a "Fastboot mode for bootloader unlock" if I attempt to enter download mode. What can I do?

Thanks a lot, once again. :rolleyes: :good:
[LG V20 Questions & Answers] AWT86:
I have now finished installing TWRP. Is the phone rooted at the end of the guide (where it says "you have twrp and h915v10e..."), or do I need to root now?

If I go into download mode, the entire screen is messed up (shows weird pink and yellow pattern of pixels, but won't display message)

However, LGUP detects the device, so I could flash the (entire?) latest US996 KDZ and then a root app (like supersu).

I wiped the data etc. but phone won't boot (stuck at "corrupted" screen).

Can I flash the latest US996 KDZ (everything) and then flash SuperSU via TWRP, do that the other way round, or what should I do?

Thanks in advance

Just to confirm, will this also work on the VS995/Verizon variant and if so, will it enable the use of Band 12 for T-Mobile and Band 17 for AT&T? Thank you.
[LG V20 Questions & Answers] Mirsaneli:
Is there any possibility to update H910 to Android 8.0 without rooting or modifying anything? I want stock ROM without root, but since I got a refurbished unlocked V20 H910 running Android 7.0, I would like to get Oreo, but no chance by tapping the software update in About phone... I guess AT&T recognizes when outside US.
[LG V20 Questions & Answers] Mirsaneli:
Is it possible to flash US996 Oreo KDZ to H910 Nougat?
[LG V20 Questions & Answers] Excudent:
Yes, it is. You will prob have to factory reset. My phone is faulty, i end up getting random reboots on any firmware other than 10r. If it goes wrong, you can always go back (recently had to use a firehose to go back, just as proof that there is almost always a way back).
[LG V20 Questions & Answers] Mirsaneli:
Where do you get KDZ for H910 in case flashing goes wrong? There aren't any on the Internet...
[LG V20 Questions & Answers] Excudent:
There are no H910 KDZ's. You either flash a compatible KDZ (Us996, H915 are sure ones), or use the firehose method (dont recoment it, just stay with KDZ's if possible).
[HTC U12+ Accessories] aaronc_98:
It pays to look in the box, as I did not realize there was a clear hard plastic case included with the u12. It fits well and allows you to see the beautiful translucent blue back. It works for now...

Yep. That case it quite o.k.

I was never using any cases, but this one is o.k. Using it now.

I'm waiting for the Brodit clip for use in my car. Probably won't use the case after I get the new Brodit.

This overlay APK it's "born" because of the necessity to overcome missing overlays (thanks Huawei, love ya xoxo) under /vendor/overlay .

What it does exactly?

Nothing more than adding AOSP overlay matching our device capabilities and also, inherits Prague power profile.

Do I need it?

Well, better having than don't.

This will conisderably enhance your experience on every GSI ROM giving better functionality overall.

Why you did that?

Because I'm sick of inheriting stuff that belongs to /vendor, in system.

Project Treble it's all about separating vendor implementation from system.

So why we should keep adding OEM stuff in there, if it doesn't belong no more in /system?

I have XYZ device with ZYX firmware can I use it?

As long as you're on a PRA-*** device (with a non-EMUI firmware), you're good to go.

Otherwise

DO NOT USE IT FOR THE LOVE OF MANKIND

.

I don't have PRA, but I want it on my Huawei device ! :( :(

Well, that's fine, join the Telegram group [MENTION=595670]GSI[/MENTION]_HI6250, so that you could help me with stock files grabbing to make an overlay for your device. :)

Overlay configs (aka "what does dis do, ser tell pl0x"):

Allows all rotations;

Configs autobrightness levels;

Configs autobrightness Lcd values;

Configs BLE;

Sets Doze Component;

Sets Doze After screen off;

Configs autopowermodes (doze related);

Configs power management on:

screen off due to proximity sensor interaction;

decouple on suspend state;​

Configs brightness doze value;

Configs Intrusive led;

Configs dual band wifi support (where available);

Configs hotswap (where available);

Configs Color Transform on HWC;

Configs VoLTE available (even tho it needs support on GSI side);

Configs WFC over IMS;

Configs wifi background scanning support.

Installation Instructions

Download the overlay from the Downloads session.

With root, push the overlay to /vendor/overlay. Create the folder if it doesn't exist.

Run the following command in a rooted terminal or ADB shell:

chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay;chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay/dil3mm4-overlay-PRA.apk

- i plan to go to LOS 15.1. Should i flash LOS 15.1 before, then install your fixes ?

- if i can go to LOS15.1 from Prject Treble, what device should i choose ? A or A/B ? I assume this is ARM64.

Hi

I've tried to install this file but after I've enter the code, it says system is readable only.

I've tried with adb shell and terminal(booth of them rooted) and it didn't work

I've even tried to mount system as rewritable but it didn't work.

I'm on Aex 6.6 latest version(and I was on PRA-LA1 8.0.0.370 C185 before i flashed this custom rom)

What should I do to fix this error?
[P8lite Themes and Apps] yorgen:
install terminal emulator , put the .APK (be sure to rename the last build taking the -P ) in the mencioned directory but first run the following command:

I was on nougat on my L21_hw_eu before i tried to upgrade manualy to oreo. i tried the twrp and terminal method and my phone started upgading. It failed at 72% saying "update verification failed". I lost my stock rom and bricked my phone.

Then i manualy flashed different Update.app images and was able to unbrick my phone .

I tried lineage OS and stock oreo.

Problems are:

1: I cant factory reset my phone using stock recovery it fails at 24%

2: FingerPrint Sensor won't work except for gestures (in Stock oreo. works in LineageOs)

3: Themes dont work

4: Flash light don't work

4: CAMERA is not responding. in both roms

in lineageOs everything works perfectly except Camera.

Please provide me details for what am i doing wrong..
[Honor 7X  Questions & Answers] mrmazak:
If you only have extracted images flashed from update.app, then you do not have the full rom installed.

As far as I know (which is not that far). You need three images to be correct for recovery to load on oreo based device.

1. recovery_ramdisk.img

2. kernel.img

3. recovery_vbmeta

try to flash those in fastboot first. and see if they complete without error.

then if they do flash, try to boot into recovery. (try with stock first-- can try TWRP after if this works)
[Honor 7X  Questions & Answers] iu.khan53:
i cant flash ramdisk images. ithink i m on naugat now because i am able to flash succesfully recovery.img and boot.img in recovery and boot partitions. but cant flash ramdisk and kernel.
