I've usu'd can't flash lineage

So, turns out that the soft brick wasn't a brick... but a display error. I decided to attempt and flash with twrp-3.2.2-PREVIEW-131_g4_O.img. I was succesful! However I've run into a couple of issue's.

1. after flashing my us991 baseband. My phone lost all cellular service.

2. I figured that I might need to go ahead and flash lineage-15.1-20180719-UNOFFICIAL-h811. This is where it gets interesting. My phone is still being recognized as US991, and won't flash the rom because it is incompatible.

So now, I'm stuck in between a rock and a hard place.

Again, any help would be very appreciated.
[G4 General] Pete_Mitchell:
Very likely this is a stupid question but what if we try to unlock and root h818p with nexus root toolkit just changing the twrp? the two phone are pretty much the same
[G4 General] sdembiske:
Flash your MM modem.bin file from your SALT backup or modem.image from your SALT stock MM rom extraction. Do not reflash the us991 baseband pakage.

Did you remove the top Assert line in the updater-script in the H811 zipped rom file? Refer to post # 947 if not.
[G4 General] Pete_Mitchell:
Maybe this is a stupid question but what if we try to unlock and root the h818p with nexus root toolkit choosing the nexus 5x line? this two phone are almost the same... Obviously twrp has to be the g4 one

---------- Post added at 07:42 PM ---------- Previous post was at 07:34 PM ----------

other stupid questions : I have extracted from oneplus 3t the engineering mode apk that can be used to inject root without bootloader unlock... can that be useful in some way? I have even downloaded the dirtycow apk, but my 20h rom has received the october 2016 security patch, will this app work if I format? the security patch should return the stock one, right?
[G4 General] steadfasterX:
this is not a h811 unlock thread and especially not for SIM unlock.

Read and follow FAQ #25 . Then boot to TWRP again and share the recovery log again.

Check FAQ #13 for your install issues and share the TWRP log when you still encounter issues (see my sig).

[G4 General] cablematicman:
That must be it. I flashed the TWRP from the OP instructions...

Downloads

YES. ALL of them:

Latest unlock package by steadfasterX (only download for your device model required) --> <model>_UsU_unlock.zip

Latest baseband package (only download for your device model required) --> <model>_UsU_baseband_flash-in-twrp.zip

Latest TWRP (PREVIEW-103 or higher!) by steadfasterX --> http://droid.binbash.it:8008/TWRP/N

trying now with the O TWRP. that'll probably fix it. Thanks!

yep, it's good now! :)

Hello, MultiRom Manager can work with the vs986 after unlock ?

I want to install more roms but i dont want to unistall this ROM.

Can you check this? https://xdaforums.com/g4/development/mod-multirom-v33-lg-g4-t3414496
[G4 General] sdembiske:
That particular project you linked was abandoned. steadfasterX tested this approach as well and abandoned it early on as it led to soft bricks (https://xdaforums.com/showpost.php?p=72790331&postcount=327). You want the ability to run two different roms? Backup both of them and restore as needed in TWRP - that's your safest bet for now.
[G4 General] lowtiertrash:
now functional no sim.

for some reason my post is getting flagged, and I can't quote anyone.

anyway..

1. I was successful in booting lineage. Everything is functional now! thank you for pointing me in the right direction!

I was operating, originally, under the assumption that all of the ROMS posted in the download section were already altered and didn't need to be touched on my end.

2. As for the SALT backup. When I try to extract a kdz from backup. FWUL\SALT doesn't recognize that I have any. I backed up my phone first thing before I started flashing UsU.

Just to confirm that the Issue wasn't on my part. I backed my phone up yesterday afternoon to see if I might've done something wrong, but alas, SALT doesn't see my backup's. Nor, can I find them in FWUL.

I don't know if this issue belongs on this thread, but I've done as much research as I could before coming back empty handed.

What I do know is that my firmware version is US99121a_03. Unfortunately, my specific model. Which I can make out to be to either the unbranded model or the rent a center model has no backups that I can find on that firmware. No dice there, unfortunately. So, I'm unclear on whether or not I can use earlier, or later MM kdz's to extract the modem.bin. Which seems to be my only course of action at this very moment. Again many thanks for the help, I do truly appreciate it.
[G4 General] steadfasterX:
Its not active developed anymore and I guess it will not work properly with UsU'd devices.

Consider to try efidroid.

Its still in Alpha state (so backup often) and it has some known issues (like the TWRP version and device detection while in TWRP is not working - due to the old TWRP version) but quite usable (I use it actually for several ROM testing scenarios)

SALT questions goes in the SALT thread. Reproduce the issue and upload the SALT log from the advanced menu and post the link in the SALT thread.

[G4 General] JMLS15:
Thanks for answering me, now I have a problem with my device.

Every time when i want to watch a video in youtube or other video player it freeze and turns in green.

I can only watch videos at resolutions less than 720p because the video freeze when i put more res than 720p, example 1080p, 720p60fps.

Im trying dif roms but all have the same problem.

This is the list:

1>lineage-15.1-20180719-UNOFFICIAL-h811 > oreo rom. >with his kernel

2>aoscp_vs986_usu-4.2-20180421-unofficial > nougat rom > with his kernel

3>lineage-15.1-20180719-UNOFFICIAL-vs986_usu.zip > oreo rom> with his kernel.

4>G4_ARB-any_v29a_FULL-STOCK-ROM_UsU > nougat stock rom 29a > with his kernel.

That's the only problem I have, everything else is good, I can play any game and it does not get stuck.

I am available 24 hours a day, in case you need to connect to irc to help me.

PD> this problem did not happen with the stock ROM MM 6.0 VS986, happened after installing a ROM.
[G4 General] JMLS15:
This is what happens when i put a 1080p video.

[G4 General] JMLS15:
Please, someone know what happens with the phone?

I think is not a hardware problem.
[G4 General] sdembiske:
The camera function is one of the most complicated in your phone's operating system. The problem mostly stems in adapting Google's software to the LG G4's hardware - the original camera app software in the LG G4 is all proprietary coded (i.e., closed source) by LG and unless LG makes it open source it makes it very difficult to properly code something akin to the original that will mesh properly to the hardware using the latest google drivers

The camera does have some issues still:

- video recording in the app works for 720p and 1080p but does not work at all for UHD 4K[/U] (the setting it loads to on install - it has to be changed in the settings gear icon in the app as it indicates cannot connect to camera for video recording but it does work on the UHD 4K setting for camera pictures).

- Video play in YouTube in 1080p 60fps still lags/freezes and has buffering issues with longer plays. Some devices seem to have more problems than others on 1080p etc.. It is also dependent on the quality of the video recording in the first place and the length of the video with respect to buffering issues that account for the lags and freezes.

My go-to camera app is still Camera FV5 Lite and Cinema FV5 Lite (free on Play Store )for video recording. Frankly, I have yet to find an app from Play Store or any of the modded Google camera apps to give me a better quality picture or better video recording than the FV5's.

Re: phone issue - You will have to go on to IRC (Monday - Friday - see the OP) and wait until steadfasterX gets to you.
[G4 General] JMLS15:
What is the point of having a 2k screen phone if you can not take advantage of it?

Before I could perfectly watch videos at 720p 60 fps / 1080p 60 fps / 2k videos.

Now I can only watch videos at 480p, because if I INCREASE the resolution the video freeze
[G4 General] ThePiGuy:
Then stick to stock LG where you could use higher resolutions - nobody is forcing you to use custom ROMs.

I think a congratulations to [MENTION=5545101]steadfasterX[/MENTION] is in order for developing UsU in the first place - without it, you would have no choice but to use LG software.
[G4 General] sdembiske:
Oreo 8.1 higher resolution Video Play workaround for You Tube videos, etc.

Not tested on AOSCP Nougat but should work on it as well.

@JMLS15; [MENTION=4256326]vsTerminus[/MENTION]; [MENTION=4302074]bdasmith[/MENTION]; [MENTION=5485572]spartan268[/MENTION]; [MENTION=9021252]Vauff[/MENTION]; [MENTION=8135713]adam_s_459_[/MENTION]; [MENTION=3110350]hey_joe[/MENTION]; [MENTION=7673578]NummerEinsNerd[/MENTION]; and any other members that have had video play issues on YouTube etc.

While this may not be the most ideal solution (ideal would be perfect play within the YouTube app, etc.), it does work extremely well and overcomes the inability to play YouTube videos on the LG G4 Oreo 8.1 roms (by [MENTION=5545101]steadfasterX[/MENTION]; [MENTION=5461026]kessaras[/MENTION]; [MENTION=8699949]ThePiGuy[/MENTION]) at higher resolutions (up to 1080p 60fps - tested).

The idea came when after playing my go-to 1080p 60fps testing video (Battlefield 1ps4 on YouTube - search it in the app) and I got a pop-up in the YouTube app suggesting that in order to overcome the buffering issues (that creates the lags, freezes etc., on higher resolution video play) I could subscribe, download their videos and pay-to-play at $10.00 US a month ... hmm, eh?... what the F... ? ____ F... that noise !!!

Solution

:

- Download Videoder: https://www.videoder.net/download/

Install the apk via adb. You can download for android and/or for your Windows/Mac PC/laptop.

You can download videos directly on to your device (recommend wirelessly to save on any data charges) at your preferred resolution or transfer the downloads to your device from your Windows/Mac PC/laptop.

Note

: I found it just as fast to download to my device directly with the app on my device. The app works a charm and even better ... it's free to install, use and download videos from YouTube.

- Download Video Player All Format - Full HD Video Player (free on Play Store) to your device:

https://play.google.com/store/apps/details?id=video.player.videoplayer&hl=en_CA

Note

: Editor's choice on Play Store.

Direct the video player to the video and enjoy problem free video play at your chosen resolution. Works a charm!

No download mode just fastboot

Model: LG-H815P

I unlocked using UsU and it seemed to be fine.

In FWUL (virtualbox)

fastboot flash recovery twrp-3.2.2-PREVIEW-131_g4_O.img

and it seemed to flash ok.

In FWUL (virtualbox) terminal I did a

fastboot reboot

and got the expected secure boot error, but code 1003.

I got into TWRP once, and only once, and realised I needed to get an sdcard to make rom installation easier, maybe.

And that's all she wrote.

I can't get into Download mode in order to check my UsU status with SALT. When I try to go into Download mode, the small blue initial Download mode image pops up and then it goes into bootloader mode. I can only go into bootloader mode now.

I've tried reflashing recovery but the same result.

Any advice?
[G4 General] steadfasterX:
Do you have grabbed the SALT debug log after unlocking as the popup told you to do?

If yes share it.

if not.. sigh..

Try FAQ #25 do bring back download mode and connect with SALT and share the debug log once connected.

Can't root after UsU

Hi

Lg g4 h810 10o successfully Usu'd and successfully install TWRP and now installing Magisk 16 via recovery, install seems correct but system ca't boot, startup screen (LG logo and secure boot error) is there forever. After sometime I again rebooted to recovery and only restore boot partition , nothing else. Rebooted and system booted successfully. But without root (obviously). So pls what is wrong. Recovery log (https://bpaste.net/show/804b6554734c).

Same thing happens when I use supersu.

Please advice, what is wrong?:confused:
[G4 General] rock2rap:
Who can make a HOW-TO Video for this method?. because I have a problem about english language. thnks advance.
[G4 General] steadfasterX:
That bpaste seems to be expired.

ensure you set the drop-down at least to 1 month

What ROM do you use? still 10o stock?

what supersu version do you try?

up to here I have no idea what device model you own. I guess its a vs986 as you mentioned the vs986 LOS rom.

so vs986, correct?

well no. Assuming your device is a vs986 I NEVER ever said you should upgrade your bootloader to v29a! Even more clear the aoscp and LOS UsU threads clearly stating that too.

That would brick your device as the bootloader stack of v29a has an ARB of 0 and - assuming again that you have a vs986 - it will have a higher ARB.

Thats FAQ #25. When you see chinese chars the raw_resources is mixed up so read an follow that FAQ.

Like I said flashing v29 bootloader on a vs986 was a STUPID idea. The FAQ you linked btw

CLEARLY

mentioned to check your ARB!

yea and to make it even more worse you started playing around with QFIL. I clearly mention everywhere that QFIL is f*** dangerous but anyways ppl still using it .

you have more luck then understanding. sorry to say that such rude but its like that. QFIL is nothing I mean really NOTHING for the average user out there. Especially not for the G4 models.

So if that was the only messages you got you may have luck as the flashing failed. otherwise you would have converted your device very likely.

a) my sdcard unbrick is the best and recommended way but you need the sdcard -> or you borrow it maybe?! Its just needed for the unbrick process

b) using a box like infinity or z3x or similar can help too but costs money

c) find someone with such a box in your local area (hard to find) or online (usually costs money)

d) find other QFIL files with the following risks (you have 0,00001% chance that the following will NOT happen - in other words a 99,99999% chance that the following WILL happen:

- will very likely convert your device

- sets a higher ARB (so never UsU anymore)

- make it useless due to conversion (no signal, no data, maybe no boot)

- hard brick (like it is rn)

- or even hard-hard brick (mainboard replacement only option)

Again I can just

highly recommend to take away your fingers from QFIL

as long as you know what you are doing.

There are several files out there named for a specific model but containing NOT that model - so will convert your device!

A video is useless as long as you do not understand all clear warnings, requirements and other stuff like the FAQ.

The whole process is complex while made as easy as possible for everyone - a video will never be able to make things such clear as written language.

I can just highly recommend you find someone who is able to translate that into your language but a video is nothing which will help you - instead it can make things more complicated if you encounter any issues.

.
[G4 General] xperia modder:
Thank you for replying , and yes my model is vs986 , and i undetstand why are you warning against qfil and i am not using it anymore , and i didnt mean to say " upgrade to v29a "

What i meant to say is i followed this becuase before i usu'd when i was on lollipop stock so i followed this:

--> Your*bootloader*stack should be on*latest MM with ARB-2*(see*FAQ #20*for how to upgrade your bootloader stack)

And after following this my phone went to qdloader, so i think am going to try the sd method , still thank you for everything and

Im planning to unlock my H12 so that I can install lineage os oreo by steadfasterX. But the op in LOS oreo says that it if ever a baseband has been flashed, clean flash the modem in twrp back up. My questions are:

1. Is it necessary to flash the baseband provided in this op during the unlocking or it is ok to skip it.

2. Or does clean flashing the modem partition from twrp back up means restoring the twrp back up modem partition?
[G4 General] steadfasterX:
Then you have not flashed either the right files (e.g wrong ARB) or you missed a partition to flash or you have a frankenstein.

Reg 1: no. The baseband package is a workaround for non USU ROMs

Reg 2: you can restore from your TWRP backup as long as this contains your pure Modem Partition or from your SALT backup which you really should do before unlocking
[G4 General] dapat:
Reg 1: no. The baseband package is a workaround for non USU ROMs

Reg 2: you can restore from your TWRP backup as long as this contains your pure Modem Partition or from your SALT backup which you really should do before unlocking

So, to summarize ur reply, I will just unlock and flash the twrp package provided in the op without flashing the baseband package. Then install LOS oreo and gapps without restoring the modem partition from my Salt or twrp back up since I would not flash the baseband package.

Am I correct, sir?
[G4 General] steadfasterX:
You forgot the most important thing ...

Besides that there is no TWRP package for unlock.

wouldn't make any sense, right because you do not have TWRP atm ;)

Basically it's like that :

Upgrade to latest MM with ARB 2 max

SALT backup (basic)

Unlock by SALT with the unlock zip

Flash TWRP in fastboot

Boot directly to TWRP afterwards (otherwise TWRP gets overwritten) and do a full TWRP backup and name it meaningful (e.g "pure stock after UsU")

Now flash a ROM of your choice or root or whatever you like to do :

If you wanna use your current stock or a non UsU ROM you have to flash the baseband package in TWRP or an UsU kernel.

If you wanna use an UsU ROM it's enough to just flash the ROM and nothing else

If you decide one day to use a non UsU ROM and so have flashed the baseband package and wanting to go back to an UsU ROM you should flash your modem partition from the "pure stock after UsU" TWRP backup or from your SALT basic backup.

Ohhh My bad I think I overlook the time period of expiry.

I'm on 10o stock from "nagalun" this post

https://xdaforums.com/showpost.php?p=77165038&postcount=38

which he had provided me as I had no backups before and after UsU, and superSU version I used 2.82.

Actually my phone didn't connected to 3g network services only edge, so slow data rate. Thats why I decided to unlock it, maybe some new ROM can change it and i can connect to faster data services. My data plan is 3g confirmed. And I need root too. After failed attempts I find this thread

https://xdaforums.com/att-g4/development/root-h810-10o-t3535028

and I flashed rootedsystem.img in twrp and its a success boot and root but again on 2g. Sometimes in both systems (both r h810 10o stock lollipop) it converts to 3g service for a short while than change back to edge. I checked my sim in (LG g3d850 unlocked, rooted and on debloated stock MM) and it works fine, not in my Lg g4h810 10o.:confused:

So thats the whole story

If u remember my posts from "[ROM][UNOFFICIAL][N][UsU]CypherOS 4.2 [H810]" thats also not worked as I was on LP not on MM. I don't have original backups before and after UsU even twrp backups.

Good point my friend. But as I have said in my previous posts, Im not used to linux or to command line. My other devices are Samsung phones and tabs and they can easily be flashed with twrp via odin in Windows.

I still do not understand why people asking random questions in random threads. If you have an issue with a specific tool for example SALT then why not asking in the corresponding thread? I mean who else than the developer of the tool you have problems with can help you best?

And when you use the right thread there is maybe a FAQ in there because many questions already have been asked or if not there is maybe described how you can report a bug by for example sharing a log file

HELP-No Cell Service after USU

I have successfully unlocked the boot loader in LG US991. I have not tried any custom ROM and using same MM ROM before unlocking the boot loader. My problem is there is no cell service. I tried flashing different modems from stock MM and Lollipop roms (US99121a, 10c, 25a, 21a, 24a) but if I do not flash _UsU_basebands_flash-in-twrp.zip after flashing stock ROM it is in a LG logo boot loop. My concern is that _UsU_basebands_flash-in-twrp.zip flashing over writes the stock Modem which I flash before that. But I have to flash _UsU_basebands_flash-in-twrp.zip at the last to get out of the boot loop. What is the solution? Please help. Also there is no kernel USU for my model or GPT compatible model. My GPT compatible model is H811.

I read FAQ 5e and LIMITATIONS / KNOWN ISSUES No.4
