Try flashing the superv20 rom by going here https://hassaanmirza123.wixsite.com/superv20/downloads and look for the H910 varient of your phone, this should give you a custom rom.
Things to note:
1. Use this custom recovery for it to work and don't worry it's for your version of the LG V20 (H910)
https://androidfilehost.com/?fid=674106145207485129
Flash the recovery you just download via flashfire from the Play Store or within the custom recovery.
2. Flash the prerequisites if you have them from the v20 rom, if not just flash the rom. (I believe the prerequisites only apply to the V20 H918 but I may be wrong.)
3. Next, you need to select the rom you downloaded and choose the stock rom version in the aroma installer then select your options.
4. Make sure you use Magisk and also choose the Custom Kernel option VERY IMPORTANT.
5. Then reboot back to the recovery and flash the same zip again and choose the modded system UI selection, if you want or you could skip this and enjoy the custom rom without any modded system UI
That should do it. If something like failed to mount system or set permission failed. Just wipe everything but the microsd card if you have one and then repeat the steps above.

need help no os in nexus one

i accidentally deleted my stock os in my nexus one. i found some stock roms but i keep getting this error every time when i try to install them
E:signature verification failed
What recovery are you currently using?
If it is stock recovery you will need to use the official google file and rename it "update.zip" and place it on the root of your SD card. Make you sure you visit the development section and read up on the procedures, as your radio version and recovery are not listed, its hard to tell from your post. If you are indeed in stock recovery...
Here is the original, official ROM http://forum.xda-developers.com/showthread.php?t=614057, make you sure you load it correctly. And of course...I am not responsible for anything that may go wrong. You will soon get the OTA update to 2.2 Froyo.
If your on a custom recovery, you should download a custom ROM. Some are based on the stock AOSP so if that's what you want you can find one like that and flash it through custom recovery after the triple wipe (factory/cache/dalvik). If that doesn't work try switching to the other custom recovery image. Aman-Ra is one, ClockWork is the other.

Black Screen, not able to get custom rom

Hi, so I've tried my best to follow all kinds of tutorials en guides but unfortunately I was only able to get miui v7 on the phone, but all the apps didn't work at all. So I tried to install other custom roms.
What I have done is to revert back to KK 4.4.2 and then root it(towelroot.apk) and flash twrp recovery(with autorec.apk). I get into twrp recovery and wipe cache/delvik & data + factory reset after that I tried
to install with the Aroma installer, but after the install I end up with dead black screen. I've read on the net that it says that I have other kernel, but I did install the roms which were meant for D802 LG G2. So I don't know what
I am doing wrong. Could someone help me out. Thank you.
You will need Kitkat basebad for this to work... Look use search button and download flashable Zip for your device... Good luck!!

Starting the root, recovery and custom ROM procedure from KitKat (D80220d-HKG-XX)

I've read pretty much every source I can find on getting a custom ROM up on my LG G2, which I haven't even rooted in the past 2 and a half years. My warranty ran out a while back and I'm getting a bit bored with stock now, and I want to start flashing, but the last time I did this was with my old HTC Desire HD.
As you can see I'm on 20d on my LG G2. It's a Hong Kong version for some reason, lol. What I considered doing was the following: update to the latest Lollipop official ROM using the LG Flash Tool (it gives me an available update to 30d); root using the rooting app, install a recovery with AutoRec Lollipop, flash a thermal recovery from the installed recovery (very scared of my phone overheating, I'm even considering putting it on a large, fast-running fan while doing anything, read too much about the phone overheating and making the screen yellow); back up my phone's IMEI data; use the recovery to install a brand new (I'm hoping a Marshmallow) ROM. I also understood that I need to flash a bootstack to change my bootloader to a KitKat, because it can be "fooled" using the BUMP thing. Is that correct? Do I even have to update my phone to Lollipop in this case? Also, how likely is it to overheat while doing all of these procedures?
Thanks in advance!
Sorry for the necroing my old thread, but I have yet to do anything with my phone. I am also still on KK. I saw that I can start rooting and install TWRP from it straight away. After that I need to flash a bootstack, right? How likely is it that I can brick myself? By that I mean what could get mixed up to get a brick while flashing. Also, has anyone had overheating issues while doing root, recovery installation and flashing things (newer TWRP, bootstacks, new ROM)?
Hi, i can understand your situation as i was in same till today, g2 with stock kitkat.
i finally installed cm13 after rooting it and the phone feels fresh.
you have understood most things right and ready now.
you dont need to upgrade to lollipop if youdont want to, you can start from kitkat itself.
few things i can tell you to begin here,
Root your G2,
for kitkat i found few good methods. Either do it via ioRoot using pc. or you can use towelroot or kingoroot apps to do it from phone itself. I used kingoroot since i didnt have a system with me. You can find these apps by searching at google, jst tyoe kingoroot. At first i was skeptical but it worked nice.
after root, you download autorec app, this is to install a custom recovery(twrp) for kitkat. you just have to install the app and run it and press install recovery/twrp and it'll do the rest.
after you have twrp installed, you need to upgrade it to latest version. For that download blastgator's twrp for your model and flash it through your recovery.
oh and dont forget to learn, how to enter into recovery yourself, since each G2 model has different method.
once you have these things you can start flahing roms. Most of the instructions on how to flash certain rom with what bootloader and bootstack etc. is written in its own thread, so you can learn that from that rom's thread that you will flash.
but basically, you need kk bootloader and lp bootstack for cm13 and above. usually both these things come in one zip. (if not you check for hybrid bootstacks)
Just make sure you are downloading things For your Model, if you try to flash different models stuff into yours, itll brick.
The autorec app, blastgator's twrp and ioroot can be found in a sticky thread in G2 general section, along with many other files and guides in that thread, theres complete index in that thread of all thing for all g2 models .
here : http://forum.xda-developers.com/lg-g2/general/05-10-index-guides-fixes-roots-t3218178
also usually the phone doesnt heat up while flashing, just make sure your battery is more than 80% before you start and itll be ok. Even if it does a little, after a custom rom itll be fixed. I suggest you try cm13 for starters as your first custom rom.
hope this helps you :good:
Good Luck ::highfive:
Thank you very much, appreciate the vote of confidence, lol.
I've actually considered installing Resurrection Remix Marshmallow. In the thread they point to the hybrid bootstack I need to install. I am on a D802 phone, so I'll be downloading that boostack. Anything I should really know before flashing that particular stack, except that I need to run the latest recovery from blastagator? Can I boot back into my old stock KK installation before putting the new ROM and Gapps on my phone and wiping + flashing, or will the phone not be able to boot that old firmware with the new bootstack? Theoretically, can the phone still get bricked even if I'm using the latest recovery + the proper bootstack? I've read that the CM13 devs don't recommend flashing bootstacks but instead using the kdz flashing method to flash the latest Lollipop release...

to upgrade from kitkat you need lp or hybrid bootstacks. they have images (. img files) that are needed for your phone to function properly., like aboot, modem, radios etc. Hybrid bootstack contains aboot from kk and everyhing else from Lp. So when youll flash a bootstack, youll need to wipe everything, except internal storage(or external if you have one) , before you can flash it. that wipe will include, cache, dalvik cache, system, data. so basically all the old system stuff will be gone before you can flash this bootstack. i hope after reading that youll know that you cant access your old kk installation since itll be wiped, therell be nothing to boot to. if youll try, it will give you errors on lg logo.
understand it like this, to install new 21 inches tyres to your car, you need to upgrade the rims to hold a 21 inch tyre right? what will happen if you just put the 21' tyres on old 15' rim or old 15' tyres on new 21' rims?
the cm 13 devs dont recommend you to flash bootstacks because most of the models took the official lollipop update, which put everything in their phone to lolipop level. since there is no official marshmallow(MM) bootstack for our phone (because no official update), everyone developed ways to utilize lollipop bootstack to function on a custom MM Rom. Since most models are already on lollipop, theres no need to flash lollipop bootstack while flashing custom rom. That step is mostly for those who are still on stock or custom kitkat based rom. So they say to get official lollipop through kdz method, instead of flashing Lp bootstack before gettig their rom. But remember if a rom developer asks to install a bootstack for their rom, you should consider it if you dont have much knowledge about it, cause if you dont follow instructions, you can soft brick, in that case youll need hybrid bootstack.
see if you are using everyhing proper for your phone then your phone wont brick. only thing that can go wrong with that condition is your execution, your steps. As long as you dont make a mistake in these steps everything will go fine.
ill explain it what you should do.
1. first root your phone.
2. when done rooting, install "root checker" from google play. itll confirm if you have root or not.
3.Then you come back here and find autorec app from the link i gave you in my previous reply. download that, install the autorec app. and follow on screen instructions and itll install twrp recovery for you.
4. then come back here again, and find blastgator's twrp, from the same link in previous post. itll be the one whih says "twrp with f2fs". download it and remember where you put it.
5. turn off phone, boot into recovery (i hope you've learned by now how to get into recovery of your g2 model). Now youll be in recovery, hit install button there and find where you put that file, flash it, then reboot recovery, youll have new recovery after that. then you reboot into system.
now upto this point, you can play along in your kk, have fun with features, say last goodbyes and all lol. Because everything stock kk related will be gone, past this point, including all the apps you have installed.
[IMPORTANT] : after rooting and installing recovery, get bootstack zip, rom zip and gapps zip files downloaded and placed together in a folder on your phone, before you start with flashing bootstack. Because you wont be able to boot back into system after flashing just bootstack.
now you prepare for MM, boot into recovery, now since you are in kk, you need to install LP bootstack, and for that you need to wipe everything using your recovery's wipe feature.
6. in recovery, hit wipe, hit advanced, select cache, dalvik cache, system, data. [ Dont select internal storage otherwise all flashing files will be gone and youll be left with a brick.] and wipe.
7. Now hit the back button to go back to main recovery screen once wiping is finished. hit install, flash the bootstack zip.
8. now your phone has new bootloader but its still empty, like you got a body but no soul . so hit back button, hit install and flash the rom zip you downloaded.
9. now flash gApps same way.
10. once its done, just hit reboot system. no other steps needed.
11. be patient, first boot takes longer than normal boot.
12.enjoy MM :highfive:
you probably know these steps from all the reading but its for your reference, so you dont screw up at all and be safe from bricking.
you can get google apps from opengapps website. you need to get ARM-> 6.0 -> (your prefered ones) pico/nano/micro/etc.. pico has the least amount of gapps, all important ones are there in pico, then extra will increase as you go up from pico to stock. stock has all the gapps. size will also increase as you go up. so choose as you prefer.
now once you have a cm13 /MM based rom, you wont need to flash bootstacks for other roms from next time unless the developer instructs to do so.
good luck

Does the cwm mm come pre rooted? Or unrooted ready from whatever idiocy I'm ready for?
1.stock
2.root
3.autorec twrp
4.upgrade to blastagators 3.0.2-1> or a different version I'm missing? This one says blastas twrp bump
5.put cwm rom, bootloader, gapps <where to get gapps zip?> onto internal memory somewhere familiar to me
5.wipe all but internal memory
6.flash bootloader
7.flash rom
8.flash gapps
9.???
10.profit
Check my steps teacher? I'm gonna start it anyway when my phone hits 80+ percent

cwm is clockworkmod, its a custom recovery. i think you meant CM 13, mm rom.
yes, the Cyanogenmod team have placed root access into the rom, so once youll be finished wih installing cm 13 rom, you can just go to settings, Tap build number repeatedly until a message will show "congrats you are a developer now". that'll open developer options in main setting screen Go into that and youll see root access. turn it on. youll have root.
you can check in root checker app to confirm root access for confirmation. you wont need super su app in any of these roms anymore.
your steps :
stock
1. root
2.autorec (for installing twrp on your phone) for kitkat its on forums, for lollipop its in google play. just get the one for your model, search for autorec in google play.
- blastgator's twrp requires you to have any version of twrp beforehand in order to install his version.
3. download and save blastgator's latest twrp, when youll go to download his twrp, itll be written there which one's is the latest version, just download that one and flash it through recovery.
4. Yes place all files in your phone, you can get gapps from opengapps.org/
select arm- 6.0- whatever size you like(, pico is lightest contains all essential gapps, stock contains every gapps)
5. wipe yes.
6. flash bootstack
7. flash rom
8. flash gapps
9. once gapps done, just hit reboot system.
10. enjoy
yes go for it when you have more than 80% battery, this is to ensure that all flashing steps go through without any issue, you dont want your phone to run out of juice while flashing rom do you that could cause soft bricks. so always keep battery more before flashing.
[IMPORTANT] : remember to read instructions of the rom you're installing and adjust the steps as instructed in there.
Goodluck :highfive:
Awesome, I forgot to.flash gapps prior to something I just did, not sure if it will cause increased global warming or thermonuclear war...update soon
@MarshisnotMellow
Gapps installed!! No Internet connection on the d800 and something sinister has happened to my unlocked WiFi Hotspot so I'll have to check for play store capabilities later!! Thanks for the help!!
I decided to go with the latest 29.10.2016 nightly of CM13 for my first run on this phone. Everything went through, no one died, lol. I'm going to start installing and restoring stuff now, get Xposed on, like I have on my TF701T tablet and trick out my phone's appearance. Just a note - after you install new bootstacks your phone's MAC address will change, so if you have a WiFi network with a MAC filter you might want to add your new address.

Need help flashing ROM on I545

Hi it is the first time I am flashing Android ROM. I have done some reading already. Before I start, I still have a few questions and also want to make sure I am doing it right.
I own the Galaxy S4 Verizon I545. It is running Samsung ROM Android 4.4.2, Baseband I545VRUFNC5. My goal is to flash a new ROM with recent Android versions, hopefully 7.1.1 (but I would settle with Marshmallow if that is more stable), it can be close to AOSP, I don't need ROMs with extra features.
In my understanding, the bootloader is locked, it will only load signed kernels and recovery. And then the kernel would load the system. In order to flash the system, it is best to flash the recovery first with TWRP. TWRP is modded with loki hack so it would load with the locked bootloader.
So here are my questions:
1. Does it matter which firmware/baseband I am currently on? For some phones (LG G2) I heard newer firmware fixed the loki hack. Should I update to the latest Samsung rom or leave it at NC5?
2. I don't see many ROM posted for the i545, which one is the most recent and reasonable stable? The Cyanogen website is down, should I try LineageOS?
3. I see different instructions for flashing TWRP. Can I flash it with just Odin? Some instruction mentioned rooting the phone first with KingRoot or other root, and then use dd. Does the phone have to be rooted? (I prefer not to if it is not necessary)
4. If after I flashed recovery, it fails to boot into TWRP, what can I do to restore everything to default?
5. The kernel will be untouched in the process right? I am only flashing recovery and system ROM, and the kernel will work fine with the new system ROM?
Here are the step and software I plan to use:
0. reset the phone to factory
1. use Odin to flash TWRP 2.8.7
2. download a ROM compatible with I545 and place it on the phone
3. flash the system using TWRP
Any feedback would be appreciated.
PS: Also I have a LG G2 D801. I would flash that phone instead if it is easier. I just want to get started and learn some things along the way.
https://forum.xda-developers.com/galaxy-s4-verizon
Oh Sorry. Didn't notice there is another forum. Should I repost there?
Yes.
1. Yes, it does matter. As you said, newer firmwares have fixed the exploits which make the phone harder to hack.
2. Any ROM should support your phone. They are generally unified.
3. In the name of anything holy, do not root with KingRoot. If you want to root, then the only way to go is CF-Auto-Root.
Rooting is sometimes necessary because recovery won't always install with Odin.
4. Flash stock ROM.
5. Kernels are specific to ROMs. So no, the kernel won't be untouched.

Won't boot into system or fastboot

Hello,
Just got it and already bricked it, hooray.
I did the Nougat update and allowed modifications (the swipe in TWRP). I'm dumb
So here's everything I did :
First I used the Axon 7 Toolkit by BKORES to unlock bootloader and flash TWRP.
At step 9), It failed to boot TWRP even tho I could access it with power+volume.
It eventually would get stuck at the ZTE logo when I wanted to boot system.
I flashed SuperSU with an SD card in recovery.
So : Fastboot and system won't work. Recovery would, and so does bootloader from this.
What should I do ?

Nah this is a soft brick, nothing to worry about
Maybe your SuperSU did some bad stuff on the rom. For exampls if you flash SuperSU 2.79 or higher on Android 6 (at least in the stock rom) it won't boot. Maybe try flashing Magisk B13? I think it gets rid of SuperSU
There's a no-verity-opt-encrypt file too, somewhere in this forum, maybe in Kernels, ROMs thread. Maybe give it a shot
Another way is going back to the stock recovery and flash an official package. I have made an easy guide for the A2017G, not sure if it works on the U or chinese. you can find it over at Guides, should be pretty close to the top
If you have an A2017U you can get the DrakenFX system files and install them, maybe you can fix the stuff
Or take the easy way, and install a custom ROM. Not the best choice unless you're willing to withstand some small bugs and stuff. The way to install them is get the A2017X_Universal_Bootstack and corresponding modem for your model, plus the ROM and OpenGApps 7.1.2 arm64 (Or beansgapps if the rom specifies), and of course the ROM itself. You wipe system, data, caches (not necessarily internal) then flash the Universal Bootstack and tbe modem, then the ROM, then GApps if you want to have them, then Magisk or SuperSU if you want root (some roms come with self-installing Magisk in the same package, too).
Or use MiFlash and flash a complete stock image of your phone's system. That one works like a charm

I flashed DrakenFX's B29 stock rom. Didn't thought it would work with recovery but anyway ! Thank you.
Do you recommend some ROMs, kernels, etc ?

Nah, they are all mostly bad. The best of the bunch seems to be NucleaRom, it has an okay kernel (Radioactive, not too good battery-wise but I've never seen so little UI lag, like, ever) and okay features (like 1/3 of what ResurrectionRemix has), an awesome maintainer (OrdenKrieger) and boots in like 15 seconds
But the stock ROM is currently the best of them all, not battery wise (you can get some obscenely high SOT numbers on LineageOS with Substratum black themes) but it's fluid and stuff runs well on it. The status bar is hideous though, and MiFavor is white themed, on an AMOLED screen, what the crap ZTE?
Don't try PureNexus, permanent hard brick from the looks of it.
LineageOS works okay but it has some compatibility problems with some apps I use, dunno
I think you could try the dual-boot patcher, that way you can test the roms and keep a working stock rom to use it as your daily driver without losing data. i never used the dual boot patcher though, so good luck if you will use it
I've bad experiences with Dual boot on my old 1+.
