Newbie to installing Roms

I have a sprint variant of the LG G2 running Android 4.4.2 kitkat and I'm interested in trying the CloudyG3 Rom, and I was wondering, what are the most simple steps to installing the CloudyG3 Rom so that I won't make any mistakes? Appreciate all the help I can get. [emoji4]

Make sure you are up to date with KK baseband and modem...then follow the instructions that he has posted, it is basic as that...
Granted that you are already rooted with a custom recovery since you are inquiring about flashing a Ported ROM
this is what I did:
DL the ROM
Place on SD card
reboot recovery
Make a back up of your current ROM
wipe everything except Internal Data (Do not wipe internal data.)
after wipe you can now choose the ROM and install
if you have white lines after first boot there are Kernels that fix it in the second post FAQ on the original thread
if you do get the white lines power your device off and boot to recovery by holding Volume down and Sleep/power button, entering until Recovery mode appears on the screen..

Ok, thanks, I'll try that. ?

Ok, I'm in recovery mode and went to wipe, then I went to Advanced Wipe, and it shows these options: Dalvik Cache, System, Data, Internal Storage, and Cache, which ones should be checked and unchecked?

Be careful of what you delete!

As hooover stated, check everything except the Internal Storage. Wiping the internal storage will delete the OS!

I am on official/stock ZVD & only rooted so far. So if it's official then it must be already on KK basband, right ?

D855 Factory reset issues

I have a question, what is the cleanest way for factory reseting the phone?
I am using a rooted LG G3 D855 now, wouldn't like to flash kdz or TOT because it is pretty complicated and although I understand most of the steps, I don't want to take the risk...
Now I would like the wipe everything clean and completely reset it to the time I buy it.
Should I just go to recovery and apply "Factory reset" option? Because I was using a special recovery to do a 5 wipe including emmc wipe (internal SD), /cache, /data, dalvik chche and /preload wipe previously in my Note 1, I was thinking that was the cleanest wipe.
But since I didn't install any recovery kernal and everything is stock except rooted, I want to know the cleanest way to wipe all data completely. Also, because the recovery (Philz touch recovery) has the option to wipe external SD as well, it makes me think it wipes things more completely and more powerful...
So can anyone please give me some suggestions? Thanks in advance. Something just tell me "Factory reset" in stock recovery isn't enough to completely wipe the phone...

You are correct. Factory reset wont completely wipe the phone. It will wipe cache, dalvik cache and data partitions. That is all the apps, personal settings and such.
Your phone will still stay rooted.
Idk what to do since you don't want to restore via kdz/tot. I suppose you could try to full unroot via SuperSU app. Idk if that works, haven't tried it.

Alright... Is this method working? http://forum.xda-developers.com/showthread.php?t=2785089
My firmware is 4.4.2 (v10n-HKG-XX), I wonder where can I find the exact KDZ or TOT (actually I don't understand these two firmware files' meaning...) because I cannot find it on the internet nor www.lgkdz.com, and I don't know which kdz or TOT I should be using exactly because it can be serious if I flash the wrong one...
Glad that you answered, was planning to reset if nobody answered me...

That guide is valid.
Don't really know if you can find the exact same version as you have now.
HKG stands for Hong Kong correct? If so I would suggest you tot flashing
these: http://lgg3root.com/lg-g3-stock-factory-firmware/
Scroll down till you find d855 Hong Kong and download the correct one
16gb vs 32gb. Also download the dll. For the rest follow the guide you found.
These are from july 2014 so they are pretty old, probably 4.4.2 same as the
one you have.
Or if you want kdz which is probably easier to flash
you could use this one: http://lg-phone-firmware.com/index.php?id_mod=41
Scroll down till you find: 145 HKG/HONG KONG V10N LGD855, download
and proceed with guide.

Alright, thank you for the information and reply. That means flashing kdz and tot will really completely totally wipe everything clean from my phone right? Including those system files, /preload, /data, internal SD card, /chche and dalvik cache and things like that?
It is the only method and there is no need to use any extra custom kernal or recovery to wipr those things manually? Is that correct? Thanks for advise.

That's correct, full wipe.
Ofc no need for any of those, you need LG Flash Tool, kdz/tot (+dll if tot), drivers. That's it.. Follow the guide you posted previously.
Happy flashing and best of luck.

[Q's] Custom ROM flashing

Hey,
My LG G3 currently running Android 5.0 (V21-SEA-XX), rooted, lastest TWRP flashed with AutoRec.
I want to CLEAN flash nightly CM13 and I have few questions:
1. After downloading ROM and GApps, where should I put them? Internal memory/SD card?
2. What should I backup in TWRP to get full backup? and where should I move the backup to before wiping?
3. What do I need to wipe to get the cleanest install possible? I own my G3 for over 2 years and it has a lot of junk on it. (of course without wiping the SD card)
4. Anything special you recommend me to backup with Titanium Backup?
5. Do I need to flash Modem? (My device is running 13.00002)

1. You can put them wherever you want. In internal or sd. If you are wiping internal, don't put it there
2. You can do a full backup using TWRP if you want a full backup of your current Rom, kernal, apps and so on. But it's not necessarily needed of you're sure that you don't mess things up.
3. A normal wipe(dalvik, cache and system) on TWRP is quite enough for installation of a rom. But if you want to wipe internal you can do that as well.
4. If you're not doing a TWRP backup, you can backup your apps using titanium backup. This is what I normally do, because I only usually need a backup of my apps and data, and not of the current rom(because we can reflash it later of needed).
5. You need to flash a 21B modem. Usually changing from stock based to cm roms requires change in modem.
And one more thing, you're just flashing a rom after 2 years [emoji15]
G3 D855---ROM : #DU ---Xposed

Thanks.
Few questions -
1. Why not flash 21C modem?
2. Can you tell me exactly what do I need to wipe in TWRP to wipe everything except SD card?
System, Dalvik, Cache, Internal Storage.. Data too?

Need help to install custom rom

Hello,
I don't know why my lg g3 phone doesn't want boot on custom rom.
I have the LG G3 d855 model, 16gb memory and here are my procedure to install every custom rom :
1. Flash Stock ROM using LGUP (the version of the firmware is not important but the possibility to root is)
2. Install KingRoot and get root
3. Install AutoREC and enter to the recovery
8. Flash Recovery TWRP 3.1.0-2
9. Reboot to the new recovery
10. ADVANCED WIPE (wipe cache, dalvik cache, data and SYSTEM)
11. Flash baseband 21C
12. Flash CUSTOM rom
13. Wipe cache and dalvik cache
14. Flash Gapp
15. Wipe cache and dalvik cache
16. Reboot
I think I did nothing bad...
but the phone does not start and it stays at the initial logo screen (not the LG logo, but the custom rom logo). I waited over 10 minutes to boot but nothing. Even though I install the identical rom again or install an anoter rom, each time the same issue.
This happens with all custom rom (xenonhd, resurrection remix, and now lineageOS)
I can use and boot on stock rom but each time I want to install a custom rom, my phone doesn't want to boot. The phone display stays at the initial rom logo screen.
It seems that I am alone to have this problem.
I don't know why and I search everywhere to find out the solution...
PS : My phone never restart by itself. I never have bootloop with my phone when I using stock rom and same with custom rom..
The problem is the boot with a custom rom. The phone don't want to boot and stay on logo loading...
Any suggestion may be help.
Thank you.

1. Once you installed TWRP you don't have to go back to stock to switch roms. From then on you can just download zips and flash them.
2. You need to delete everything (including system) except internal and external storage ( so you can still flash the zip for xceed, otherwise you will delete it). Remember that you will lose all your apps including your data with it. You can backup them with titanium backup tho. Pictures and video's will still be there as they are stored on the internal or external storage.
3. You also need to flash the GAPPS package after flashing rom, for xceed (7.1.1), pick nano (ARM)
4. Wipe cache and dalvik after flashing and reboot.
5. Make a backup before you do so !!!!!!
Good luck.

Hello,
1. I think that but with specific rom, some people tell us to flash stock rom before flashing a custom rom. eMMC bug related ?
2. Deleting the system changes nothing because the system is wiped when I flash the rom, right ?
3. if the rom boot first then I will install Gapps. Else, I don’t install because the rom doesn’t want to boot.

1. Well .. I've been switching between fulmics,xceed,rr, .. etc without any problem so no, there is no need to go back to stock everytime.
2. Try it, you won't be able to boot until you flash a new rom, but it could help. That's why you take a backup in the first place. It is more 'clean' and if you don't try it you won't know.
3. Sometimes you have to flash gapps directly after the rom or you will be in for a bad time if you do afterwards.
Once you have TWRP recovery installed it's the easiest thing ever to flash a new rom. Make sure your zip files are downloaded okay. Download the MD3 to check it. Try to download via MEGA app or so, because browsers downloads tend to have errors sometimes.
Apart from that. Don't root via kingroot. They have had some suspicious cases where malware was installed on the phone when rooting.
If nothing's works. Go back to full stock through KDZ, root wit your PC, install TWRP via autorec, go to recovery, wipe everything, install modem 21C, install rom and gapps, wipe cache, reboot. Don't try anything other than that.

I have the same problem

Hello,
I have a question.
Can you give me a gapp 100% compatible with all custom rom with android 7.1.2, because i think opengapp are not reliable. Maybe the gapp will cause my issue and the rom won't boot.
Can i use this one https://forum.xda-developers.com/on...isited-slim-gapps-6-0-7-0-unofficial-t3462088 ?
I always use PICO version of gapp
Thank
