[help] Really slow boot time on LG V30? - LG V30 Questions & Answers

My V30+ was fine until I flashed a new ROM (LineageOS 16.0) and then it started booting slow, now taking like 2-3 minutes. I reset everything in TWRP recovery and flashed back to Lineage 15.1 but it still occurs. Is there something I could have messed up? Has anyone else had this issue?

You're saying on stock your phone takes 3 minutes to boot?
On rooted stock firmware, from the time I hit "Power off and restart" through bootloader unlock warning, LG boot animation and back to my wallpaper is 56 seconds.

Have you tried flashing an Oreo KDZ? I'm not sure, but you may need to do that if coming from a Pie ROM like LOS 16. You can then try flashing the Pie KDZ afterward.

I tried Resurrection Remix 17, and then I flashed stock Pie - that was a problem.
In download mode I saw, that something is wrong with partitions - some notice in red. So I go back to Oreo - flashed KZD Oreo in LGUP, and then again KZD Pie. Now boot time is normal. Thanks for tip

flashing error?

So i had a hardricked phone(i thought) but than it worked again. So i flashed pacrom and it went in a hardbrick like state again (using twrp btw)I flashed it with nano gaps and the b330 package so you could get the fingerprint scanner. Than after an hour or so it worked again. Than i started running my battery low on purpose so i knew if it was just stuck or if it was something else. When my phone dies it will reboot again and work. And then i flashed rr with the nano gapps and the b330 package and it did this again, I thought it might have something to do with the b330 package so i flashed it without and it still did this. Then i thought it might have something to do with my twrp because i was still running on version 3.0.0 so i flashed the newer version through fastboot and it did this again!!
I dont know what is going on but my phone is acting really strange.
Does someone know of this problem or has ever heard of it or is my phone just strange?

you need to consider putting your phone back to stock using the dload / update.app for your version nd leave it their until you figure out if your phone is broken or not. flashing roms is just confusing the situation.

Hi Jim, Indeed you need to fully revert back and see if it works.. i will provide you some links since we are from the same region/country.
1. Flash the stock recovery
2. Download this file and put the update.app in a file named 'dload' on the root of your sdcard.
3. Shutdown the phone hold Volume Up+Down and Hit the power button it should start booting and applying the update. Just leave it for like 30 minutes and u should be back at B130 firmware. Then you should receive a update for B140 and once you are on B140 u can upgrade back to B330.
Report back if it worked or you encountered any other issues!

did you take all the updates to b330 ? if so you can pretty safely go to CM13 + gapps nano without any worries.
use one of the newest versions of TWRP
Do a factory reset and flash only CM13 and gapps
reboot let it fully load .. reboot to recovery / backup your fresh install to ext-sd
boot back to the OS and setup your new device.

Phone stuck in bootloop for no apparent reason.

So recently, my phone went into bootloop for no reason. I was using stock firmware, no root or modifications of any sort.
I'm not able to access recovery mode, boot the phone(in safe mode as well). The only screen I was able to get to was download mode.
However, I don't want to flash custom firmware on it because that would make me lose my data.
Help of any kind to help me backup my files or fix the problem would be appreciated.
UPDATE: I was able to install TWRP onto the phone, but it freezes after the first of seconds of boot.
Is there any important data on the phone? If not, did u factory reset it?

It's the G925I - the international variant. I bought the phone in India and it was latest on nougat.
Should I restore the Marshamllow version instead?

Hey sorry for the late reply... I had to travel and bought the OP5 in a hurry.
Tried flashing the firmware you gave, but it had the same result - bootloop.
Any luck? Mine just did the same thing this morning. To be a little more clear, my ph-1 (USA, Sprint purchased) ran the battery out last night. When I plugged it in, it bootlooped. I entered boot loader and shut it down. Fast forward - charged all night, no difference. Bootloader is locked and there is no recovery (phone hasn't been modified at all, unless you count Holy Diver as a ring tone

Sorry for the late reply.
I gave it to a service center. They simply replaced the battery and it was working fine for a day. The next day the same things started happening again, and I sent it back to them.

help! signal drops

I upgraded to nitrogen os 8.0 few weeks back. all going ok but flashed firmware update few days back and continually getting signal drops. the signal does not hold for longer than few minutes then disappears and comes back while later. Every rom I have tried since suffers from the same issue.
I have tried to flash miui 8 and miui 9 but although they eventually flash they stay on bootscreen (poweredby android screen) and never load. I left it overnight on that screen and never loaded?
Any help greatly appreciated. any help of any kind :crying:

U should flash miui using Mi flash tool or if u wanna stay on nitrogen oreo or any custom rom u should first flash the latest firmware available before flashing any rom

Having the same problem of signal drops in evry single rom. Its really bad to see developers not doing anything about it. And regarding that flashing, if u flash official miui by official twrp, then it will not boot. U have to use modified twrp to flash the official firmwares.

No solution till now. Getting frequent internet disconnects. The only thing which is keeping me in the custom rom is the adoptable storage , cause m using the standard variant 16gb and its internal storage sucks.
For twrp, refer here:
https://forum.xda-developers.com/redmi-note-3/how-to/guide-redmi-note-3-available-twrps-t3406708
same issues here, running LOS official with default kernel, had the same problem always. I thought it might be antenna related as I had to order a new usb daughterboard due to poor microphone, (had reception issues with a note1 in the past due to a fake usb board lacking gsm antenna) but I think this is not the case here. Always updating the latest firmware hoping that can help but so far not.

soft brick help please VS996

Hello friends:
seeking help with a soft brick V30+
Story: I've been running stock VS996 20i on a converted LS998. Now TWRP gets stuck on splash screen(TWRP-3.2.3-7-IntSD.img) after trying to dirty flash VS996_20j on an encrypted device. Mistake??? I think so, cause now phone wont boot to OS or to Recovery.
In download mode connected to LGUP+V30DLL_PATCHED; phone shows the VS996 20j.
Question: How do I get recovery back? Can it be done via download mode? Do I need to downgrade back to Nougat or can I reflash recovery from LGUP?
Thanks all!!!
20j TWRP has been having some issues. Take a look at that thread for help on how to get it back. You may just have to KDZ back to a working version. I hear the KDZ works fine, just the TWRP is failing. It's a work in progress still.
When I got stuck with 20j only way out was to lgup us998 N then to us998 O.. That was with DL partition tho.

So you basically Frankenstein'ed again, but your bootloader was already unlocked.
I'm sorry but has no one tried flashing 20i again................... Because that literally worked dozens of times for all the debugging I did for john.

The first guy said he lost TWRP, so he couldn't flash the 20i zip again. And flashing full KDZ 20i in LGUP would just give stock VS996 with no fastboot flash commands to reinstall TWRP. Unless I'm misunderstanding your suggestion.

The zip wouldn't have gotten rid of twrp. It does nothing to the recovery partition. It just doesn't work that way.

Let me add a quick query here or start new thread, idk. Us998, messed up recovery, laptop says unauthorized device in adb. No boot either, what are my options?
Been out-of-town for a bit, so just wanted to thank everyone who contributed remarks.
As described before...after the dirty flash of 20j, phone could/would not boot back into recovery. It either boot-looped or got stuck on the splash screen. So I decided the easiest way to get working was to use LGUP to downgrade back to N. Essentially, repeating the Frankenstein process. Now I'm back to 20i again.
I'm just wondering if it was the encryption which caused the issue to begin with. Perhaps there is a conflict with dirty flashing ROMs on an encrypted OS?
IIRC, flashing over encrypted Data partition almost always ends up with bootloops, no boot or in worst cases a brick. But then that's in twrp. I don't think lgup flashing does that since it repartitions everything if you go with DL..

LG V30 bootloop

I tried restoring from a twrp backup when I got stuck in a bootloop. the phone boots up into lock screen then after a couple seconds restarts.

Also, after you go back to US998 Nougat with Refurbish, then do the Master Reset, and when you refurbish back to Oreo go ahead and go to 20H KDZ.
Your bootloader should still be unlocked, I would think. (However, if you don't see the bootloader unlock warning after Nougat and Master Reset, then go to 20b)
From 20H, then you can reinstall TWRP, and flash the three root files again (no encryption, root check disable, and Magisk).

I don't see that you first flashed Nougat, then did Master Reset before going to Oreo.
Nougat would be 10c or 10d (your choice).
Oreo starts in the 20's.
Frankenstein Instructions say to flash Nougat, then Master Reset, then go to Oreo. There's a reason for each step I don't have time to explain here.
Something about your phone is messed up and doing Frankenstein over (Nougat, Master Reset, then Oreo) should fix it.

It DOES work if you flashed the right firmware.
If you have a constant bootloop and Master Reset doesn't fix it, it means you usually have flashed the wrong firmware.
I'm betting that you tried to flash Oreo first instead of Nougat.
What letter/number US998 Nougat did you flash? Did you use Partition DL mode?
Please read Frankenstein Instructions again. You should be asking in that thread if you are trying to convert one North American variant to another.

If you already have US998 V30+, why are you flashing US998 Nougat? What are you trying to achieve?
You don't need that for bootloader unlock -- you need early Oreo 20a or 20b. The only reason to flash Nougat are for North American variants who have to convert to US998, before flashing US998 Oreo 20a or 20b. Most can't flash directly to Oreo 20a/20b, they have to first flash Nougat, and do Master Reset, then flash early Oreo.
Were you using Partition DL or Refurbish? Read the Master Reset directions again.

If you press the buttons long enough, hopefully it will reboot.
Still didn't answer why you were flashing Nougat, when you already had USS98 firmware? You only needed to flash USS98 20b.
I'm afraid you unneccessarily flashed it because you didn't read instructions carefully, so I don't know what else you didn't read carefully...
Hope you get it working again!
