Lg G2 VS980 wont go past Lollipop for me? - G2 Q&A, Help & Troubleshooting

I need some help, anyone, please! I have a Lg G2 VS980, rooted supersu by chainfire version 2.79 latest, i guess. twrp 3.2.0-1 by blastagator, and running resurrection remix 5.4.7(Lollipop 5.1.1) from stock rom VS98024a which i pushed with lgtool14, i believe. From stock VS98011a which i also installed a year ago when my ParanoidAndroid os Lollipop rom 5.1.1 just stopped working all together dont know why, still. tried flashing over that with lollipop CrDroid rom Lollipop 5.1.1 when the phone bricked. So I proceeded to start from scratch again learning as i go, im kinda good like that sometimes. so i did all of this all is working well and good again, except for one thing, when I try to flash any custom marshmallow even nougat roms they install like the lollipop ones fine, matching micro Gapps packages every time for marshmallow and nougat roms. wipe the dalvik and cache properly, all is good til reboot of the system. Lg logo comes up then black screen and nothing else ever, Ive let it sit for hours and nothing. i dont know what i am missing here i know its possible to go past lollipop but im at a loss here. ive searched til my eyes bleed but there is no comprehensive guide on how this is accomplished and what to do with the black screen issue im facing. i dont know if i need to do a bootstack change or something else i dont know about. If i could get some guidance here maybe a solution to this issue. hell i dont care if i got to start from scratch again. something guys. if you need any info i havent provided ask. and yes i have all the proper latest drivers, adb, fastboot, and even latest android studio from google, which i dont have a clue as to how to use. im not a noob but by no means a developer, lol.

lg g2 keeps restarting

Hi.i have lg g2 d800 32gig.it was with stock 4.4.2 and from time. To time it freeze and restart itself. I install. Cm 12.1 lolipop snapshot.and it keep doing it,every houer or so.i even unolugged the motherbord and installed again.what is the prob??
Probably one or more than one apps causing this.
Try another rom. I never use CM base, let alone a snapshot/nightly. Install Resurrection Remix M, it's based on CM stable and is faster and has more features.
But the device also restart. With the stock rom 4.4.2. Is there maybe prob in the motherbord?

could it be or maybe a stuck or sticky power button?
Hi,idont think its asticky power,because it happends 6-8times aday.not all the time.i dont know how to fix this prob...
boot stack
I had the same problem. Install boot stack first then flash CM then gapps.
More likely its a hardware issues. Or May be something has to relate with Bootstacks.
I have lost My G2, In no point return mode! So move on with other device. Honesty G2 isn't made for all people. That's all I can say.

Could use some help figuring out what to flash

My girlfriend has been begging me to update her Verizon S5 for months, so I've finally started reading my options, and I'm lost. Right now her S5 is just stock rooted, still running 4.4.4. I was going to install Resurrection Remix N KLTE but I just realized it requires an unlocked bootloader, which I've determined isn't possible on her phone. I was hoping to find a ROM based on Nougat that she would like but besides Resurrection Remix I didn't notice one. Really all she cares about is being able to theme her phone like she has now using the Wanam module for Xposed. I'm thinking of just getting her to stock MM and installing Xposed but the post I read mentioned boot loops on Samsung devices, and that there were unofficial builds that fix that, but didn't link to any. I'm also not sure how to either keep root or to reroot once on MM. It's been over two years since I rooted her phone, and I recall having issues. Anyone have any advice? Links? a spare S5 with an unlocked bootloader? Ok the last one isn't necessary but the first two would be appreciated.
the only thing that i'm really surprised that your girlfriend
i mean you cant find a girl who knows in android very much everyday XDDD
anyway sammobile is the first place

Jiyu s3 basic 2gb upgrade

Hello thanks for letting me join this forum i have two stock kitkat 4.4.4 s3 basic mobiles that need updating any help would be appreciated in doing this as ive never done this before have tried to flash but dont seem to work ive got root gapps etc .looked at twrp etc but it wont update cleared cache etc can anyone point me in the right direction as i am a complete noob at this .Thanks .OK guys ive updated one to 5.1 have you any recommendations next operating system can i flash twrp flashify windows 10 a nightmare with sp flash tools got there in the end thanks.
Yeah, I had the same problem too. I'm using: [ROM] [6.0.1] Unofficial Sandstrangers LineageOS/CyanogenMod13 , Haven't had any problems so far, and it seems just as fast as the stock ROMS.
Assuming the lollipop ROM you flashed is the same as mine, you should be able to flash any new ROMs directly from TWRP now.

Moving to LineageOS worth it (and possible) from Cloudy G2.2?

I've been running Cloudy G2.2 for a year an a half. It's given the phone enough legs to mostly make it through 2017. However, about every other week I have to restore my latest backup when Bluetooth stops working because it saw too many devices. This wouldn't be terrible if it wasn't for Authy refusing to sync my newer 2-Factor auth accounts. I think I've convinced myself that the G6 (US997) is my next phone, but now is a silly time to buy as the price should drop like a rock as the next wave of flagships come out.
I'm hoping to make it another couple months and was wondering anyone's experiences moving from Cloudy G2.2 (or other ROMs) to the latest lineage? From what I've read, it's very stable. However, I'm on Kit Kat bootloader, so it doesn't seem like this will be a straightforward process. I was hoping to get some experiences from people who made the same move before starting.
I currently have:
LG G2 D800
Root using stumproot (I think, it's been a while) with supersu installed
TWRP 2.7.0.0 installed by autorec
Cloudy G2.2 KOT49I
So, after some research, I set off to install LineageOS. In hindsight, this might have been a bad idea since it specifically only mentions the D802 in the title. However, it listed links for D800 builds, though they were crossed out.
I updated TWRP to this version by Blastagator and that was painless. I then wiped the phone, made a fresh backup and flashed the latest nightly of LineageOS, and the latest GApps (Mini) for 7.1. That was disappointing since I got the quick "LG logo" followed by a blank screen, that I later found was mentioned in the same Lineage post. Should've read farther.
I think the issue is that I'm on the wrong bootloader. I thought I was on KitKat which the post requires, but in order to enter recovery, I have to press enter three times (rather than using volume buttons to navigate), which indicates I'm on JellyBean bootloader.
So, this is the scary step that I was hoping to avoid. My big fear is that I run Linux on my desktop, so I can't use the LG Flash Tool. As long as I can keep a working recovery, I have backups, so I'm fairly safe. Following the Blastagator bootloader post, I'm not really sure how you go back and forth between bootloaders so easily as it suggests. Is that really as simple as loading the zip file on the phone and installing it in TWRP?
Is there a safer way to handle this?
From my experience, it is that easy. Simply install the zip file and you have loaded a new boot loader. Also, I was in the same boat as you with Cloudy rom and moved to Nougat with crDroid. However it's not stable and I am considering looking for something else more stable but fast like crDroid.

When you updated your bootloader, were you still able to run the Cloudy ROM before you switched to crDroid? Once I flash the KitKat bootloader, am I only able to use the Nougat ROMs? My big concern is that there might be something a bit off with my bootloader, so I won't be able to get back to TWRP.
I think there's something a bit off with my bootloader as is, because about a year ago I flashed back to stock Jellybean, and took all the OTA updates. However, when the phone tried to take the KitKat update, it softbricked, and could only be recovered using the LG Update Tool, which I don't have access to anymore. Because of this, I'm a little worried that just dropping on the Blastagator KitKat bootloader may have some atypical issues.
i m using it for a while. u know, on Los you won't be able to use lg features such as qslide, qmemo, plug&pop, knockcode etc. Only worth it if you want your phone to look a little bit fresher and lighter or you need a newer android version for some reason. Else, don't take the risk if you can't use flashtool. You can consider installing another kitkat rom. There are lots and they are nice :]

My primary issue is that KitKat (or whatever Cloudy G2.2 is?) has the old Android bluetooth bug where once it sees too many devices, it stops connecting to anything. I have to make sure to turn off my phone if I go somewhere like an airport, and have been having to restore my clean Cloudy backup about once a month. It's getting pretty frustrating. On the other hand, I'm hoping to upgrade to an LG G6 (US997) in a month or two when the V30 release pushes down on prices. So, if it's a case of potentially hard-bricking my G2 at the worst possible time, I should hold off flashing.
I think you need hybrid bootstack for android 7.

That makes sense, but will I not be able to use my Cloudy 2.2 backup after that? It says that the hybrid bootstack will only boot CM 12.1, CM13, and LP stock roms.

These questions if this works with that or that are easier to answer for yourself by reading what goes with what.
Just Google LG G2 bootstack and you can probably find the ones you need for any available rom.
I use hybrid on Marshmallow 6.0.1 but I tried Nougat 7.1.2 too, it works.

Where to start with my second hand rooted G2?

I got a second hand LG G2 (D802) that appearantly was rooted, but is running a stock ROM and recovery as far as I know. It also has the SuperSU app installed. I wish to flash Lineage OS, but don't really know where to start. I've flashed custom ROMs and recoveries on Nexus devices before, but this is slightly new to me.
My worry is that I might not start at the right point, since my device is already semi-ready. Could somebody point me in the right direction, please?
