best way to run multiple ROMs ? - G3 Q&A, Help & Troubleshooting

What's the best method to run multiple roms and switch easily between them ?
Also to backup/restore apps between roms.
I'm using multirom on my nexus 7, but don't think they will work on the g3 as twrp is bumped.
Ps I'm rooted, twrp'd with bump on a d855

[Q] twrp install and dual root / unroot roms

I'm new to this stuff so apologies in advance.
I'd like to root my nexus and run/install sky go (UK TV streaming app) at the same time but sky go does not work on rooted devices. I've searched the forums and the interweb but I can't find a solution to this issue with the latest/tablet version of sky go. It seems that the root detection is quite good in this app. very annoying.
so plan B is to setup my nexus with two rom's that I can quickly interchange. One would be stock 4.4.2 unrooted and I'd use this for sky go. The second rom would be rooted and what I use day to day.
Is there any way to do this? What are the options? I am assuming that I will need to use Titanium backup (or similar) to backup data.
Any thoughts or suggestions appreciated.
second question.
I think I need to install twrp using command line method - for general rom management. It says to download the file but is this to the nexus or the computer that is connected via USB?
It also mentions to 'Run the following command via the command line: fastboot flash recovery recoveryfilename.img'. I am assuming from the computer. correct?
Thanks.
MultiROM Manager might be a good way to go. Have your primary ROM rooted and a secondary ROM installed just for Sky Go.
I'm not sure how you would be able to install a custom recovery without root on the stock ROM. What you can do though is keep the stock ROM rooted and multiboot a different ROM that does not have root built into it. (Those Roms would be the ones where you have to flash superuser)

Forgive me as I'm new to this but soon as you install superuser you will not get sky go believe me I've tried all different ways it simply not gonna happen that's what stopping me from rooting my nexus !! Its a bummer for sure !!!!

Install xposed and this.
Oops, nevermind, I guess it can't cloak from Sky Go, sorry.

[Q] Root + Recovery question

Hello,
I always had a HTC, so I'm kind of a new with rooting and unlocking an LG.
I have a LG D855 international and I have been reading a lot in this forum and I think that I've figured it out. But I just wont to be sure.
So if I'm right than I can root my phone by running purpledrake. When I've done that I have to install SU.
But if I understand it correcly the only way to get twrp is with" Bump'ed TWRP" so it's only possible to have TWRP if I use a custom rom?
So it's not possible to have orig Rom an TWRP? Right?
But If I just root my phone with purpledrake, so without installing TWRP and without custom Rom, I would still be able to use EXPOSED? RIght?

Yes Purple Drake is currently the most reliable root method, once you have root you need to install the SuperSU app of your choice.
Don't confuse yourself with Bump! Just accept that this is the only recovery that works with the G3 and install it then use it like normal. You will only be able to flash custom kernels (and roms with custom kernels) after they have been bumped, this is something the developer will do for you not anything for you to be concerned with, and fairly soon (when this method is released) all custom roms and kernels you find on xda will be pre-bumped - so basically you can treat the recovery like you always have done.
Xposed is nothing to do with recovery and everything to do with having root access.
Does this recovery back up my stock rom safely? I'm hesitant to use it because I've never heard of bump.

Nope, afaik, once on bumped twrp, u can't restore stock recovery. For that you will again have to flash the stock KDZ.
OK so it's only for bumped roms. Thank you

The user above you is wrong and didnt read your question properly.
You CAN back up your stock ROM, just install bump, head to recovery and do a backup - you will never get stock recovery back though, unless you flash a KDZ with Flashtool.
But yes you can use TWRP to back up your currenty stock ROM.
Okay I get it the only way to restore the rom that I backed up is to add bump to it! ok I got it but in order to get back my stock phone I'm going to have to use the LG flash tool right

[Q] Lg G3 with Lollipop: Custom kernel & Overclocking ?

Hello everybody,
Recently I bought a new smartphone - LG G3 (D855) 32GB with Lollipop 5.0.
Until now I've always had Apple devices and I was very deep into jailbreaking and stuff like this.
So now I want to understand a little bit more about how this kind of things are done in android. I've already read a lot (tons of stuff in different websites and forums) but unfortunately I wasn't capable of finding the information I need.
I've already rooted my phone but now I want to overclock it because I feel it a bit laggy from time to time and that really annoys me. The thing is that in order to overclock the phone I need a custom kernel (as far as I know). And here comes the problem - to flash a custom kernel I also need a custom recovery (correct me if I'm wrong) and from the things I have read untill now I could not find a reasonable and simple enough solution of doing so.
So the question is as follows: Can I put a custom recovery on my LG G3 running Lollipop in order to flash a custom kernel and how, or if not is there a way of flashing a kernel without recovery or even overclocking without custom kernel at all on Android 5.0 ?
Here are some specifications of the phone if there is a need:
Android version: 5.0
Baseband version: MPSS.DI.2.0.1.c1.13-00048-M8974AAAAANPZM-1
Kernel version: 3.4.0
Build number: LRX21R.A1421650137
Software version: V20h-EUR-XX
And yes I know that I can do it by downgrading to KitKat but I don't want to. So I am asking all this things especially for Lollipop.
Sorry if there was already a post like this but as I told you I've read really thousands of stuff already and couldn't find working solution, so I decided to ask since this could be helpful for others as well.
Thanks for all your help and answers in advance.
Best regards and I hope we will solve the problem
First you'll need to root your phone. The easiest method of doing so is w/ avicohh's one-click script...
[Guide] Root LG firmwares (KitKat / Lollipop) - One click script
http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
Next is to install a custom recovery, the easiest method of which is via TWRP Manager...
https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager
And custom kernels are flashed via recovery. Just point TWRP to the download directory on you internal or external SD that contains the file to flash.

I have already rooted my phone, so we can skip this step.
The problem is that I can't install a custom recovery. I actually even tried your method with the TWRP Manager but nothing happened (the app actually installs the recovery but when I reboot into recovery, there is nothing happening, just a black screen), so I had to reinstall my stock recovery again.
Is there some other method to install a custom recovery or am I doing something wrong?
Today I tried to do some more research in order to find something but there is nothing on the Internet.
Please help
So finally I found a way to install a custom recovery. Now when I already have it I have flashed a custom kernel (rin kernel) on my Lg G3 running Lollipop 5.0 in order to overclock.
The problem is that when I try to overclock the phone with some CPU app like "setCpu" it actually shows me that I can set the max value to 2,7 but when I click it nothing happens. The device still sits on the default 2,5.
Please help.

Best upgrade path to lollipop

I'm currently rooted and bumped, twrp 2.8.5.0 and android 4.4.2
I was waiting for xposed to be available before upgrading, and am now thinking about using a newer 5.1 based ROM
What's the best upgrade method ? (Preferably giving me an option to switch back if I need to )
I like the idea of multirom, but I've got the 16gb version so space is at a premium

Depends on what you want? Do you want AOSP or Stock ROM
Aosp is fine, but what would be the difference between the two v methods ?

Nothing too significant
AOSP you would install from KitKat and then install most of the lollipop system partitions after if necessary
Stock Rom you would just OTA or Flash Lollipop KDZ and then root
Thanks, I'll look at this today.
easiest way to get to LP is by getting your current firmware from here: http://lg-firmware-rom.com/
then upgrade to that kdz from with lg flash tool 2014, from here: http://forum.xda-developers.com/showthread.php?t=2797190
then root with this tool: http://forum.xda-developers.com/lg-g3/general/guide-root-lg-firmwares-kitkat-lollipop-t3056951
then, use an appropriate method correlating to your model number. try imageprep.
I'd suggest restoring, not upgrading to LP.
to roll back, you can of course create a nandroid before all this. move it to your ext_sd card before any flashing, too.
as for xposed, it says it's in alpha, but i haven't encountered a single issue with it and i've been running it for a good month+. tweaksbox works like a charm too.
as for multirom, i've never tried it, so can't speak for it.

Rooting - Marshmallow best method?

There's a ton of conflicting info on the interwebs about "how to root" the htc one m8.
I've got an unlocked UK HTC One m8 running the most up to date MM at the moment.
I've just unlocked the bootloader (via HTCDev and ADB) and now I want to root it and then update to use Android Revolution HD rom.
What's the best method? I'm guessing I just flash TWRP and then Flash SU and then Flash the ROM?
Can someone confirm and confirm the correct files I should be using and where to get them... there's so many different places/info
Any help please? :good:
This belong in Q&A, I'll ask the mods to move it.
You don't need to root before flashing a custom ROM, unlocked bootloader and custom recovery is enough.
Flash current TWRP 3.0.2 using fastboot. Then put the ROM on the phone, and flash it.
Okay, that last bit is a bit over-simplified. Before flashing the ROM, you should do a few things: You should make a backup in TWRP of your stock ROM, so you can easily revert if anything goes wrong with the ROM flash (and just good to have a backup of the stock ROM). Backup any data you want to keep, with you method of choice (copy to PC, Titanium backup, cloud, etc.). Then do a default Wipe in TWRP, then flash the ROM.
After the ROM is installed, it will already have root. No need to do anything separate for root. If you were just trying to run the stock ROM, but with root; the proper process would be unlock bootloader, TWRP 3.0.2, and current stable SuperSU (2.78 at the moment).
Super, all done now thanks.
Although I think I'm going to look for a stock droid ROM I just don't get on with sense that much.
Any recommendations? Looking at GPE or CM13 I think.
Cheers

I prefer Sense, so no, I don't have any recommendations.
I'm also not big on ROM recommendations in general. This is a good case in point, as my preference is already different from yours (Sense vs. GPE,AOSP), so what good does my recommendation make? In the time you asked for a recommendation and waited for a response, you could have just flashed one, and tried it yourself for a few hours now. Which is a better path anyway,since only you can device whether you like the ROM or not.
Touché!
And thanks
I will probably do just that and flash this evening and test... I read somewhere about root on GPE being problematic and/or duo camera not working on CM13 guess I'll soon find out!

The ROM installer for the stock GPE ROM in the Development section, lets you pick root when you flash the ROM. It can't be any easier.
Other GPE based custom ROMs are all pre-rooted (as is typical for most all custom ROMs).
Even if stock unrooted GPE, the root process is the same as any other MM ROM for this device (which I already describe in a previous response): Flash current version TWRP 3.0.2 (which you should already have) and flash current stable SuperSU (2.78 at this time).
If you are reading root is problematic for GPE, its probably very outdated info.

Duo camera requires the Sense camera app, and there is no reason to think that Sense features would work on CM13 (which is somewhat obviously missing the Sense framework).
Not positive, but I believe it is possible to install the Sense camera on GPE, since GPE does include the required Sense framework.
