Hello fellas
This guide is just a quick how-to on dual booting. Many people have doubts on how to dual boot on Siyah, because it's something new and perhaps "scary" because they may think it can brick their phone.
___________________________________________
Requirements
A Galaxy S II I9100
3.x Siyah Kernel (3.2.x preferred). For latest version, visit the Siyah Kernel thread
90% charged battery
2.5GB of free space in your internal SD card
Patience
Time
So, do you complete all those requirements? Time to go to action. BUT BEFORE, a brief FAQ in a simplified way, based from this post made by the amazing droidphile
___________________________________________
FAQ
Can I dual boot Ice Cream Sandwich and Jelly Bean?
Yes you can, using Siyah v3.5.2.
1) What is dual booting?
Dual booting is the ability to boot into two different Ice Cream Sandwich-based ROMs (like CM9 and AOKP).
2) How is this done?
This is achieved by sharing the kernel and using a hidden partition in dev/block to store the 2nd ROM's /system and the /sdcard (Internal storage) to store /data and /cache inside a hidden folder (/sdcard/.secondrom)
3) How much does it take to clone a ROM?
It should take around 7 minutes
4) I want to dual boot fasturr. wat do?
When you get the splash screen to choose between ROMs, touch the screen or press volume UP to enter the PRIMARY ROM, and press the Home button or volume down for the SECONDARY ROM.
5) How can I remove the Dual boot and its partitions?
Just use the "Remove 2nd ROM" option in the Dual Boot options menu.
6) If I format my /sdcard, will my second ROM go kaput?
Yep, because you're wiping the folder that contains /data and /cache.
7) Can I dual boot a gingerbread ROM in a ICS ROM?
Niet. No.
___________________________________________
Now, the PROCEDURE
You must flash the Siyah kernel, either with CWM or ODIN
After you have flashed the kernel, reboot and let Android upgrade itself.
All done? Alright, move up to next step!
Download the desired ROM that you want to make it secondary, and place it in a safe place in your internal SD card
After that, reboot to CWM Recovery, and navigate to "Dual Boot options"
You'll see a list of options, namely :
View current status
Clone 1st ROM to 2nd ROM
Clone 2nd ROM to 1st ROM
Swap 1st ROM with 2nd ROM
Swap 2nd ROM with 1st ROM
Remove 2nd ROM
Install 2nd ROM from Internal SD card
Install 2nd ROM from External SD card
Wipe 2nd ROM data/cache
Wipe 2nd ROM dalvik-cache
Fix 2nd ROM permissions
What does each one mean, you ask?
View current status - This option will show you the stats of the dual booted ROM.
Clone 1st ROM to 2nd ROM - This option will copy (clone) the current ROM that you use (for example, CM9) and paste it to the 2nd ROM directory. Takes around 7-20 mins.
Clone 2nd ROM to 1st ROM - This options copies the 2nd ROM (after installed of course) and pastes it to the place where the 1st ROM was, replacing it.
Swap 1st ROM with 2nd ROM - This will swap the 1st ROM with the 2nd ROM, making the Primary ROM -> Secondary ROM and the Secondary ROM -> Primary
Swap 2nd ROM with 1st ROM - This will do the exact opposite of the above option
Remove 2nd ROM - This will completely wipe and remove any 2nd ROM files and folders
Install 2nd ROM from Internal SD card - This option is to flash the ROM to the 2nd ROM directory from the Internal SD card
Install 2nd ROM from External SD card - This option is to flash the ROM to the 2nd ROm directory from the External SD card
Wipe 2nd ROM data/cache - This will wipe the 2nd ROM data and cache. When it's done for the first time, it'll create data.img and cache.img and create the folders inside /sdcard/.secondrom, preparing your phone for the 2nd ROM.
Wipe 2nd ROM dalvik-cache - This will wipe the dalvik cache of the 2nd ROM
Fix 2nd ROM permissions - This will fix the permissions of the 2nd ROM
Select the option Wipe 2nd ROM data/cache. This will prepare your phone to flash the 2nd ROM. It takes around 5-7 minutes.
After having that done, select the option to wipe the dalvik cache.
After all that is done, select either "Install 2nd ROM from Internal SD card" or "Install 2nd ROM from External SD card" depending on the location of your ROM
Wait a few minutes for the flash
Reboot
Press the Home button or volume down to enter the Secondary ROM
___________________________________________
After you have done all that, you're set and you're in the Dual Booting world! I hope that this guide helped you, and if it did, press the thanks button!

Droidphile - For his great FAQ
Nice. Great for people who are not sure how they going to set up their dual boot option.
Edit: What about mounts and options, where you need to format the /secondrom_cache, /secondrom_system and /secondrom_data when you try to setup the very first time? If this step is not taken, you won't be able to have the option to choose either 1st or 2nd rom. Only subsequent reflashing of 2nd rom, then you just need to wipe 2ndrom cache and data.
Unless Gokhanmoral had changed his kernel, I think this is the most important part.
Please correct me if I am wrong.
Nice tutorial, very clear...
One question: I want to dual boot to a stock ICS rom for use a MHL adapter (resurrection remix dont support it as most of the AOSP/AOKP roms)... appart of that, what uses can you give to dual boot?? I cant imagine more!
whats wrong with this guide which is in the first post of siyah thread if people fail to read the faq prior to doing this instructions are pretty easy anyways even tho your guide is more clearer and pretty lol and you have taken the time to do this you will still get the some old questions beening asked lol.
anyways best wishes to you
Maybe it is time GM gets a section in XDA specifically for Siyah ...

It seems that kernel was changed recently. What I did for my current dual-booting (used Siyah 3.2.3 that time): Wiped data/cache and dalvik of 2nd rom and just flashed new rom from recovery. I didn't format any partitions and had no problems at all with possibility to choose a rom at boot. Regards
Perhaps you can put in the GUIDE FAQ that step 9 doesn't flash the kernel image if present in the zip. (Assuming that it doesn't flash anything other than the /system and /data partitions correct me if I'm wrong)
The first time I used it I feared that I would mess up because I knew that the zip had the kernel img inside.
Good tutorial, thanks!

What about the 1st time when you set up your dual rom? I remember that there were a few people who had written in saying they do not have the option of booting into the 2nd rom after following the method describe by the OP.

Belive me I did only what I wrote to you. I did not format any partitions and had no problems at boot at all. (Boot option to choose 2nd rom has been available). To be sure I have asked this afternoon also droidphile (author of very helpful guide and experienced on this topic). This is his answer: http://forum.xda-developers.com/showthread.php?p=26742671 Regards. Happy if helped.

My intent was to make it even easier and more accessible/straightforward. My guide is meant for first timers, while that guide is more for people who have basic knowledge, which isn't always the case.

Replying to both of those quotes, wiping data/cache creates data.img and cache.img. GM did a great job on dual booting, now it requires fewer steps.
Not booting second rom!
Hey there its a good tutorial but the problem is that its not booting the second rom! My primary rom is Resurrection Remix v2.0 and I want to dual boot Cyanogenmod 7.2.0 RC3 but I do everything and when I go to boot it and press the home button to boot into the second rom it just displays a blank screen with no boot animation. Any help would be appreciated!
Thank you!
Catley!
Sweet...Siyah
Cool Tutorial...Been using dual ROMS on my GS2 for about a week now...works like a charm...gives a chance to try out all those cool customs ROMS...

Currently ICS Sammy and AOSP roms can be dual-booted so it's possible.
If you have .zip CWM flashable rom file:
1. Flash Siyah kernel
2. Flash your rom as 2nd from dual boot CWM menu
If you have .tar Sammy rom file:
1. Flash Siyah kernel
2. Clone 1st rom to 2nd
3. Flash Sammy rom as 1st rom from for example mobile odin - remember not to loose root so when you open rom .tar file then when all partitions are recognized change in odin stock kernel to Siyah.
4. Swap 1st and 2nd roms.

Great info and easy to follow, will give it a try and see the results
Hi,
I have Resurrection Remix 2.0 as my 1st ROM with Siyah 3.2.7.2. I'd like to add Slim ROM as a 2nd, but Slim comes with the Fluxi kernal as part of the zip. Will that screw things up?
Greetings everyone. I wish to know more about flashing Resurrection Remix...
I watched the brief instruction on official XDA thread but I wish to know more detail...
- Current Phone Status -
My G3 D855, 32 GB memory, is running stock Android 4.4.2, ROM version “V10n-HKG-XX”, stock recovery, rooted with PurpleDrake (script by xda developer”. Kernel version 3.4.0. All things are stock except I have rooted, with SuperSU.
- Reason of wanting to flash Remix ROM -
I wish to change resolution to 1080x1920, even 720x1280. So I did this using build.prop editing and “wm size 1080x1920”，“wm density 480”. However in stock rom, build in LG apps like Phone, Messaging, Calender will crash. I fix this by installing Xposed & app settings with DPI 530. But I don’t quite want this to be the solution...
Plus I noticed there really are battery difference between 1440x2560 and lower resolution. So I started to think about custom Rom. I found that Resurrection Remix and Paranoid Android are quite slim, good looking, most importantly very customizable.
And Stock ROM has many software that I don’t need, so I wish to give it a try.
- My question -
I haven’t flash any custom rom before (I have flashed on my previous phone but messed up quite a bit).
- So I wished to know what is the prerequisite, anything that need to pay good attention into? I want to avoid bootloop or hard brick...
- Should I install official TWRP recovery on my current status and make a full system backup image? (is that called nandroid backup?)
- If any error occured, can I use TWRP recovery to restore everything in my current status (everything in stock but have root access)?
- Are the custom roms contain build-in Root access? Because I want the phone to be rooted.
- I use LG Flash tool 2014 to flash stock firmware kdz files), with CRC method to completely wipe the phone and back to stock. Is this method still applicable if I want to back to stock after flashing RR rom? Because I want everything to be clean each time I flash a new system...
- I watched YouTube video that changing AOSP rom resolution won’t mess up icons or apps. So I can still receive SMS, dial, calender sync to Google etc. Correct?
--------------------
Finally, I wish to flash the latest STABLE version of the Remix ROM / Paranoid Android ROM. Would be good to hear some recommendations. I wish things to be more customizable and slim. Thanks for reading this long article in advance!

1- you're good to go now, you don't need any prerequisite, you should pay attention to the steps you make to flash TWRP and rom not to do it wrong.
2-yes you should install latest official TWRP for your phone and backup these partitions (system, data, boot, efs -if available-), and that is nandroid backup, and you will use TWRP to flash RR or PA.
3-yes you can restore from nandroid backup.
4-yes both roms has built-in root access that can be activated from developer options, and you can simply flash SuperSU.zip in recovery after the rom and gapps to use SuperSU app to manage root access if you don't like the built-in root.
5-yes this method is still applicable, because all you need to get back to your stock or flash another rom is wipe (system, data, cache, dalvik cache) and flash the rom, so as long as the tool does that, then you're good.
Also if you're not sure you can do the wiping in TWRP first, then boot into download mode and then flash with the tool.
6-changing dpi in custom roms may cause some apps to crash, however i don't recommend lowering the dpi value too much or you will get some issues like that.

Mr. Migo, thank you for replying. But I have more to ask/... Sorry for being annoying, because I am a beginner and I wish to make things clear, to minimize the chance of accident...
1. you said i'm good to go now, but shall i need to .kdz flash the stock v21a-HKG-xx which is Android 5.0 first? because i remeber RR rom's post in xda said i should upgrade to 5.0 first... i'm not quite sure...
https://forum.xda-developers.com/lg-g3/development/rom-t3507493
above is the link of the rom, I wish to know is my phone appropriate for doing this before everything... Hope Mr. migo you can have a look for me when you have time...
2. regarding twrp recovery, i read this: https://forum.xda-developers.com/lg-g3/development/recovery-twrp-3-0-0-0-t3309475?nocache=1 however in the official download link it said twrp for d855 europe... I'm D855 but not europe... If I want to flash official latest twrp recovery, shall i use 'twrp manager' from google play?
plus, it said i should backup the original stock recovery, how do i do that?
3. Doing a full nandroid backup which can be used to completely restore current status, only including 'system, data, boot, efs', the 4 partition, correct? because i didn't use any custom recovery before, so i wish to know more... any other things need to pay attention before doing a full nandroid backup?
4. I wonder which version of Gapps I should flash / appropriate for the RR remix... the post said Download Gapps (ARM 7.1 Pico/Nano/Other), but which I should use? 'cuz it is essential I think...
5. Hope you can check my understanding below: if i want to flash RR rom now, should:
--- flash official latest twrp recovery
--- go to recovery mode (twrp) & backup 'system, data, boot, efs', the 4 partition in ext.sd card
--- still in twrp recovery, do 4 wipes 'system, data, cache, dalvik cache' (I want a very clean installation, not 1 byte of previous rom data will be left, so how can i wipe it to very clean status?)
--- after 4 or 5 wipes, do i need to press 'factory reset', 'wipe cache partition' these 2 options?
--- alright after all the cleaning, still in recovery while the device is like a shell (nothing, no OS inside), browse to ext.sd card which I will be putting the .zip ROM file, and flash it.
--- after completing flashing, do i need to press 'factory reset', 'wipe cache partition' these 2 options?
--- then I shall flash gapps?
--- then, reboot device, and I am done?
6. I want to know is this ROM really appropriate for my phone... because all those screenshots are in foreign language, not even English, I live in Hong Kong and I bought this phone in Hong Kong... So will the RR remix rom not compatible with certain regions...
7. Again this link: https://forum.xda-developers.com/lg-g3/development/rom-t3507493 below 'Download on AndroidFileHost (AFH)', there are several version built in diff. dates. It seems that the latest build is Nougat android 7.0...? Willing to try that, but is it better for me to go to Resurection remix official site and search for d855, then download the latest, stable (not Nightly) builds?
8. This is how i change DPI. I calculate using dpi calculator, 1440x2560, 5.5inch device should have 534.06... dpi, then i use nomone resolutrion changer to view the default settings (1440x2560, 5.5inch = 640 dpi), then 640 / 534.06 = 1.19836...
then, dpi calculator agaim -> 720x1280, 5.5inch device should have 267.6532... dpi, then 267.6532 times 1.19836 = 320, I will do this in terminal with command 'wm size 720x1280', then 'wm density 320'. and go to build.prop, find "ro.lcd.sf.density' change value to 320, then reboot.
Is my method correct? I think it is not too low... Approproate value for 720x1280 res. monitor.
----------
That's all for now, sorry for so many questions... really... I just wish to minimize and get everything clear before proceeding, since this can be dangerous... thanks a ton Mr. Migo.

1-sorry i didn't know that you have a lollipop update, yes you must upgrade to lollipop first to have the latest bootloader.
2-about TWRP, if the model number is d855, so it's for you, the country won't matter, like for me if i have i9100g so i can't flash TWRP for the i9100, so if you are sure about the model number then it's ok.
You can flash it with adb or by using flashify app from phone, you don't have to use the TWRP app.
As your phone is already rooted, you can backup stock kernel and stock recovery using Flashify app, just download it from playstore and open it, grant root access and choose the tile "backup/restore" and you will see the options to backup stock kernel and recovery.
4- gapps are not complicated, "ARM" is your processor architecture, "7.1" is the android version you choose based on the rom you are flashing, "Pico, Nano.." these are the gapps types, pico has the least requirements to run the play store, Nano has extra functionality that isn't available in play store, and micro has more apps..and so on, However, if you want to understand more about it, you can read the wiki of each package from here.
5- flash the TWRP, in recovery backup is based on the phone partitions, every phone has those 3 partitions (system, data, boot) some phones have efs and some not, so when you are in recovery you will see what part are available to backup, now for wiping, you only need to wipe once not 3 or 4 times!, navigate to wipe and choose advanced wipe and mark (system, data, cache, dalvik cache) and swipe to wipe, you won't need to use "factory reset/wipe cache partition" option at all, now flash the Rom and then Flash Gapps directly, no wipe between, now reboot and wait, that's it!!
6- as i told you in (2), your model number is d855 and the rom is for d855 then it's compatible with your phone, people use their own language in their phones so don't let that bother you.
7- RR remix doesn't have nightlies and never called stable it's only official, if you go to the download page of RR of your phone in sourcefrog you will see only "official" and the "nightly" folder will be empty, however, latest build for you is in 12/2 but i don't know what CK is in the file name, i suggest you ask in the rom thread what CK mean because i don't know.
8- in nogut you don't have to do any calculations, in display settings of the rom, there is an option called "screen size" where you can adjust it to (small, smaller, smallest, normal), anyway you method can do the job if you didn't like this new feature in nogut.
OMG, i never wrote that much..?
-------------------------------------------------------

1-sorry i didn't know that you have a lollipop update, yes you must upgrade to lollipop first to have the latest bootloader.
2-about TWRP, if the model number is d855, so it's for you, the country won't matter, like for me if i have i9100g so i can't flash TWRP for the i9100, so if you are sure about the model number then it's ok.
You can flash it with adb or by using flashify app from phone, you don't have to use the TWRP app.
As your phone is already rooted, you can backup stock kernel and stock recovery using Flashify app, just download it from playstore and open it, grant root access and choose the tile "backup/restore" and you will see the options to backup stock kernel and recovery.
4- gapps are not complicated, "ARM" is your processor architecture, "7.1" is the android version you choose based on the rom you are flashing, "Pico, Nano.." these are the gapps types, pico has the least requirements to run the play store, Nano has extra functionality that isn't available in play store, and micro has more apps..and so on, However, if you want to understand more about it, you can read the wiki of each package from here.
5- flash the TWRP, in recovery backup is based on the phone partitions, every phone has those 3 partitions (system, data, boot) some phones have efs and some not, so when you are in recovery you will see what part are available to backup, now for wiping, you only need to wipe once not 3 or 4 times!, navigate to wipe and choose advanced wipe and mark (system, data, cache, dalvik cache) and swipe to wipe, you won't need to use "factory reset/wipe cache partition" option at all, now flash the Rom and then Flash Gapps directly, no wipe between, now reboot and wait, that's it!!
6- as i told you in (2), your model number is d855 and the rom is for d855 then it's compatible with your phone, people use their own language in their phones so don't let that bother you.
7- RR remix doesn't have nightlies and never called stable it's only official, if you go to the download page of RR of your phone in sourcefrog you will see only "official" and the "nightly" folder will be empty, however, latest build for you is in 12/2 but i don't know what CK is in the file name, i suggest you ask in the rom thread what CK mean because i don't know.
8- in nogut you don't have to do any calculations, in display settings of the rom, there is an option called "screen size" where you can adjust it to (small, smaller, smallest, normal), anyway you method can do the job if you didn't like this new feature in nogut.
OMG, i never wrote that much..

Sir you helped me alot, no problem I pressed the thanks button! But can I continue asking? Won't be too much I guess, hope I didn't bother your time...
1. That means I have to use LG Flash tool to flash stock 5.0 firmware (.kdz)? Which is 'V21a-HKG-XX'. But stock firmware 6.0 (V30c-HKG-XX) had released too. What exactly should I do beforehand...? Because before you said I am good to go but there seems to be something missing...... I am not challenging you sir, I just want to be sure and not missing any important steps so that my phone turns dead... (for sure information I wish to flash resurrection remix latest official 7.0 Nougat firmware)
2. So if what said in (1) is true, I need to flash stock 5.0 or 6.0 kdz first to turn the phone into clean stock 5.0/6.0, root it , then use Flashify to backup stock kernel/recovery (these are 2 things? I thought that was the same thing...), correct?
3. I found twrp recovery here: https://twrp.me/devices/lgg3europe.html by typing 'device' on the upper right, then type D855, all it appeared is only "TWRP for LG G3 Europe"... Plus, I notice in ROOT G3.com that twrp had different version for Android 5.0 and 6.0... So I am confused again, because if the above link is official website for twrp, it didn;t state that lollipop(5.0) and kitkat(4.4) has different twrp...
4. Derived from (3), as I am not sure which twrp .zip file should I download, I saw on official twrp web that it recommends "official twrp app" to install the recovery, I think it can detect my device and find the only appropriate one for me? I saw quite some people flash it using Flashify app, but I just want to know more and make it clear...
5. https://forum.xda-developers.com/lg-g3/development/rom-t3543815 <- In this page, I found
"ROM OS Version: 7.x Nougat
ROM Kernel: Linux 3.4.x
ROM Firmware Required: 4.4.2/6.0 + TWRP
Based On: LineageOS"
On below. Is that mean 4.4.2 or 6.0 as the current system android version is also okay for flashing it?
6. In this page, which is another RR rom "stating" it is official: https://forum.xda-developers.com/lg-g3/development/rom-t3507493, said that:
GApps - opengapps.org (ARM-7.1-PICO)
On below. Firstly, can I download Gapps on here: http://opengapps.org/?
If possible, than shall I choose like what it said, ARM, then 7.1, then PICO ( yes I think I only need minimum package)? Because I am not sure I should use 7.0 or 7.1, and ARM or ARM64...
7. Seems there are quite many version of RR, I googled "resurrection remix' go to their offical page, redirected me to sourceforge, https://sourceforge.net/projects/resurrectionremix/files/d855/Official/ I think I will download the latest date "20170110" version. If I am not wrong this should be the official not nightlies build (you will notice there are nightlies).
Refer back to (6), which type of Gapps should I use... AMR64, ARM, 7.0? 7.1?
8. So wiping 'system, data, cache, dalvik cache' these 4 things will really erase all things and get clean enough?
Also, https://forum.xda-developers.com/lg-g3/development/rom-t3543815 here, below:
-INSTALLATION INSTRUCTIONS-
- Download the latest build
- Download Gapps (ARM 7.1 Pico/Nano/Other)
- Take a nandroid backup
- Recommended - Full wipe and factory reset
- Flash ROM using latest TWRP 3.x Recovery
- Flash Gapps
- Reboot.
- Enjoy!
They recommend press factory reset... Should I do the same? Is it better to press because if the 4 wipe 'system, data, cache, dalvik cache' is clean enough then reset is not needed...
--------------------------------
Opps....... Really sorry sir... When reading your reply one by one that much question appeared again... Really sorry, hope you don't find me annoying... SInce you are the only one reponded and you are experienced, so I wish to grap the chance to learn about it... Thanks a ton. You can have as many thanks button pressed if you want, I have no problem!

1- ok, when they said rom firmware required:4.4.2/6.0
I believe that it's ok to root and backup the recovery, and directly start the process of flashing, because you already have 4.4.2 installed which is kitkat and it's compatible with latest TWRP, you can make sure by re-asking in the rom thread if you can directly install the rom right now or upgrade the firmware to 6.0 first.
2-(2) is connected to (1)
3- just use the latest TWRP you find for your phone in the official TWRP page, you don't have to use TWRP app, you can flash it with flashify, but it's OK if you want to use TWRP app, in fact, it's more safe to use it, and it has nothing to do with your android version because you will format the phone after all.
4-(4) is connected to (3)
5-(5) is connected to (1) and (2)
6-you choose ARM then 7.1 then pico or nano
and again, you must know that android version must be known in order to choose right, so if it's 7.0 then choose 7.0 gapps, and if it 7.1 or 7.1.1 the choose 7.1 gapps.
7- (7) is connected to (6)
8-yea. Wiping those 4 is completely enough, and don't worry about (factory reset) because it's a part of the full wipe, (factory reset) means wiping data, cache, and dalvik cache, which is already a part of the wiping process.
No problem, it's ok to ask, we all want things to go well

Okay. Some offtopic question if you don`t mind.
- Did you use any app to manage app start on boot? I mean when you boot the phone which app will auto start. I knew that AutoStart and ROM Tool box pro contains that option but I dont know how the process works.
- Which app you use to kill tasks? I use Greenify to hibernate apps when locked screen，plus recent task built-in to do the job. Any good suggestion?
- Do you use Titanium Backup to uninstall system app? I will but sometimes I am not sure what the app does but still think its useless to me and delete it. Such as WAP service. I mean in stock firmware，which still dont know although Googled. Do you know how can i know what the app does?
- What is the custom rom you recommend the most and what is the good point of it?
- I have installed Xposed framework in my current status, I mean stock rom, although I am goong to wipe anything but will it affect the process? Shall I clean uninstall it first?
I think thats it. Almost finish my questions. Thanks again.

1- ES Task Manager, i used it to manage start up apps.
2- i also use greenify along with an app called "Advanced Task Killer Free", they make a good team for me ?
3- i don't use Titanium backup, uninstalling system app is an easy process and can be done using many apps, for me, i use Lucky Patcher to uninstall system apps, works good for me.
4-custom roms differ from phone to another, for my s2 i use AICP, i always liked it in marshmallow and in nogut, i also used RR but it has a huge battery drain, also many users like XOSP, it's a wonderful project, and it's very common, so overall i use AOSP roms, but when it comes to battery life, i use Neat Rom, it's stock based with many customizations and great kernel too.
5-no xposed won't affect the process, because you will wipe everything eventually.

I will try the process later to see of this works... But...
1. customization & battery are the 2 factors I concern, i dont know how to see if the rom has good custmization and battery tweaks in their threads... https://forum.xda-developers.com/lg-g3/development Any tip or suggestion?
2. titanium backup has the option of "wipe data" of app when uninstall, which I think is cleaner for uninstalling, I mean no leftover of apps including system app. or you have better ideas about doing this?
3. Internal Storage is part of the full wipe, is it? I mean "system"/"data"/"cache"/"dalvik cache", because it contains many current status' files, I should wipe it. Correct?
4. Can I wipe external SD card in TWRP after installing the rom? Because I saw Android/Data or Android/obb files there, so I think some data files are in ext. SD card. For clean installation, I should wipe them too right?
Thanks.

Well, the as a 8 don't have lg g3 then, it's a something i can't advice you about, but AICP is a great project that can balance between both; battery life and customizations and it has a good performance also.
Uninstalling apps isn't that big deal, when an app is removed all its data is removed except media files and some low size or even empty folders, so it's a something i don't usually think off neither should you, it's nothing.
Internal storage isn't a part of "full wipe", but wiping it is up to you, it's your choice.
You do too much thinking, you don't need to wipe neither internal nor external sdcard, i have a 16GB phone and i don't think that much about this
