[Q] switching between lollipop roms - G2 Q&A, Help & Troubleshooting

Hi, my g2 is running stock lollipop. If I want to try an aosp lollipop based rom I just need to wipe the old system and flash the new one? I do not have to flash any other stuff life "back to kk" or be worried about the sensors or modem, or recoveries am I right?

anyone?

no sir, if you are on stock Lollipop you are not clear to flash any ROM's, do you have a custom recovery?
Apologies, as I have not tried the OTA lollipop....how is it? Worth trying in place of a constantly rebooting CM12-based phone?
You will need to be running a 4.3 bootloader before flashing the Lollipop ROM's, so you will need to take some steps to downgrade.

So we just have to flash jelly bean bootloader true recovery if I come from stock lollipop to an AOSP rom?
And what if we want to go back from AOSP to stock lollipop?

Root after manual update?

So I finally found some time for my unlocked and rooted nexus 4. Right now it is on 4.3 stock and I want to update to 4.4.2. Now the question which I couldn't find an answer on Google: Do I loose root after manual update? I've seen some videos on that, but some say that you need stock recovery (I have TWRP), but nothing about root.
Also, I'd install Franco kernel after that.
Help and possible tutorial would be appreciated, I'm still kinda new to android.
You can have a stock experience by installing the Experience ROM in the development thread.
Make sure you are running the latest TWRP before trying to flash a 4.4 ROM.

Yes, always when you flash another stock Rom, you will lose root.
But it's a matter of seconds to reroot after flashing latest supersu.zip through TWRP.

Flashing CM11 on Knox-Enabled Device

Hi there,
I have a Galaxy S4 i9505 with official Samsung 4.3 Stock ROM from a different country which I had flashed using ODIN a while ago. I already have my knox counter tripped to 0x1 because I had also installed custom recovery and rooted.
Would I be able to flash CM11 (Android Version 4.4) on to this and then if I don't like it or want to return back to this exact version I have now by a Nandroid backup, could I?
I have searched around and can't seem to find the answer and want to get rid of Touchwiz (like nearly everyone else)
Baseband Version: i9505XXUEMK8
Build Number: JSS15J. I9505XXUEMK8
Thank you in advance

Yes you can easily return back to the saved nandroid backup you have in recovery
I first started on cm11 before picking a daily ROM that was suitable for me
Happy flashing

I have read somewhere that if the build number is updated then you cannot downgrade or something?
Was yours a knox enabled rom and have you tried going back to it?

Apparently once you update to 4.4.2 you can't downgrade to 4.3 but IMHO why you would want to go back is beyond me ? Mine was on Knox after 4.3 ota but took the plunge & glad I did & wouldn't need to go back to an outdated OS. My baseband has stayed mk9 even after trying a few ROMs & love the smoothness of Google edition ROMs over cm11
I would suggest making the move over to kk & trying a few ROMs out there.

I have been on CM10.1 before and the only reason I went back to Touchwiz was because there was bugs with it and that's the same reason I might want to go back if I flash it now so I just want to be sure
I was thinking that if I update and my baseband/build number stay the same then I might be able to downgrade again if I wanted to later?
Absolutely hate Touchwiz right now but everything works too

I wouldn't like to say that if baseband stays same that you could go back for sure ? Touchwiz is just too bloated IMO that's why I decided on a custom ROM ?
I found cm11 okay but feel that kk GE is so much fluid :highfive:
I think it isn't possible to go from a knox-enabled rom to one without knox?
So I have knox-enabled 4 right now and guessing when I go on CM11 it'll still be there so when I try to downgrade I should be able to?
As it's not going from 4.3 (knox-enabled) to 4.2 (knox-disabled) but from 4.4 (knox-enabled?) to 4.3 (knox-enabled)
I'm not really sure but can someone give us some help .

So you was able to go from one CM11 to GE which both are on 4.4?
I think I'll update to stock 4.4 and then from there create another nandroid and move about ROMs? Would that work?

Yes initially I was on stock 4.3 then went on cm11 for a week or so then started trying out GE ROMs ?
If I needed to go back to official stock (warranty) I would just find & flash 1 through Odin :fingers-crossed:

If you needed to go back would you go back to an official 4.4 or 4.3 then?
Do you think it would be a good idea to just titaniumbackup everything and Nandroid and flash cm11 and so if there are any problems I could just flash stock 4.4 and install all the apps back via titanium backup?
Would there be a problem with the bootloader?

If I needed to go official I would flash back to 4.3 as that's what I'm meant to be on.
Always make a backup before flashing that way you can reinstall.
Can't see a problem with bootloader even if you had to flash official I would just use chainfire to gain recovery/root again ?

But this new knox thing on the S4 means you can't downgrade the bootloader or something. So I think going from 4.4 to 4.3 is downgrading the bootloader? And so would risk bricking your device which is why I don't want to attempt it unless someone has done it and had to problem

You are already on the new bootloader with Knox triggered so there is no downgrading to old bootloader.
You are safe to stay on 4.3 but if you put 4.4 or cm11 on your phone you may not be able to go back to an earlier version?
Hi, I hope I can clear something here. If you are on stock 4.3, rooted and Knox 0x1, you can flash cm and you can restore your 4.3 backup. If you once triggered your Knox to 0x1, it's not possible to get it back to 0x0.
If you flash a stock Samsung 4.4.2 KitKat with the new KitKat bootloader, you can restore any custom 4.3 ROM. You can not flash a 4.3 stock ROM with Odin once you are on the KitKat bootloader. In this case you have to flash a stock KitKat ROM.
Another thing: if you now are on a 4.3 bootloader and you flash a 4.4 ROM, it could break wifi. But there are fixes possible with editing the build.prop.
So fact is, no matter what ever you do, if your Knox is already 0x1, it's not possible to get back to 0x0.

Hi there and thanks for your help but could I clear this up
You said 'If you are on stock 4.3, rooted and Knox 0x1, you can flash cm and you can restore your 4.3 backup.'
I am on stock 4.3, did you mean CM10.1 (Android 4.3) or CM11 (Android 4.4)? And if CM11 then that would mean I could go to android 4.4 and then back down to 4.3 stock if I wanted?
And flashing a KitKat ROM on 4.3 ROM would give me that wifi problem?
So do you think I should flash stock 4.4 using Odin and then flash CM11.. and then if wanted I could just go back to stock 4.4? Would there be a change in bootloader between 4.4 roms?
Hope you understood this, thanks again

If you want 4.4, you can flash the stock Samsung package including the newest bootloader and modem. Wifi and everything else will work then. Once you are on the 4.4 bootloader, you can switch between all 4.4 ROMS, stock or custom. You be able to Odin flash the stock Samsung 4.4 ROM again. But you can not flash a STOCK SAMSUNG 4.3 ROM again. 4.3 CUSTOM Rom is possible.
Remember: if you flash the Samsung stock 4.4 package, you have to root and flash a custom recovery before you can flash cm11 I suggest TWRP 2.6.3.1, works perfect.

Understood, Thank you!
Hmm, would I need to delete data and stuff when flashing stock 4.4? If it does, titaniumbackup backup/restore should work fine?
I will flash twrp custom recovery using odin but how about a root? Which root works on 4.4 with knox?
Thanks

Try CFautoroot first. Then recovery. Restore most of your data with titanium should work. But don't restore any system apps.:good:

[Q] Flashing Kit Kat Based Custom ROM

Hi ,
I just got my G2 Yesterday , rooted and flash TWRP right away on the stock 4.2.2 . I am tempted to try out some Kit Kat based custom roms now. I have a few questions
1-) Can i directly flash KK based custom rom ( after a full wipe of 4.2.2 ) ?
2-) Would i be able to go back to my stock rom via nandroid after KK custom rom ? i.e going into recover and flashing the backup again ? ( heard there are not custom recoveries for KK ? )

1-) Yes, kinda. Just look for instructions in OP of the roms. This one works pretty well: http://forum.xda-developers.com/showthread.php?t=2667714 (Only D802 there are LG KK Roms for other variants though, just search the forums)
2-) No, there's no custom recovery for 4.4.2 yet, but devs are getting close. Read more about that here: http://forum.xda-developers.com/showthread.php?t=2667227
Edit: One more thing: You can of course flash AOSP 4.4.2 roms and will keep custom recovery.

Only AOSP? I just got this phone and I'm familiar with adb and the rooting/recovery process but does this mean I could install a 4.4.2 version of cyanogen or paranoid android or BeanStalk over 4.2.2 and keep my custom recovery?

This depends on your variant. The D800 kitkat has been moded to allow a mixed match of partitions that allows the previous loki enabled recovery to run. This was released yesterday But Is only possible thanks to the release of the kernel source for the D800 from LG. Other variants will follow. In fact the D800 versions from AndroidUser0011001 and garyd9 will flash from your custom recovery, no LG Flashtool required

Thanks guys !
I think its better to stick with stock rooted for now and jump to KK when all the necessary stuff is made available. So that jumping between KK and JB is easy .

Stock Rom

Hello guys. I need an advice pls.
I flashed a galaxy s4 i9500 (international) with sokp Rom. (Aosp based 4.4 Rom)
Now I want to flash a pure stock 4.4 Rom. Which I never had on my device. I started with custom Roms from 4.2.2, moved to 4.3 and then the custom Sokp Rom. So I need words of advice.
Is there a flashable latest stock rom which I can flash in twrp? If yes, are the steps the same as flashing custom Rom?
Where can I get a link if such?
Thanks in advance.

You can flash through odin a stock rom from sammobile or a custom rom generated from stock from xda where you can flash the zip file you pput on the microsd card for i.e. with recovery. But original stock rom which might be used to restore original condition (for warranty reasons for i.e.) should be flashed with odin or kies.

SOKP
I like SOKP rom but i can`t figure out how to make S VIEW Cover work?!

I don't even know lol

Its been a very long time since I've had to dig this deep into flashing and I've always been a Samsung user so I'm somewhat use to the less difficult route. I'm running the 4.4.4 mokee ROM with the kitkat boot loader. Im trying to get miui running on my phone. The miui ROM is on 4.2.2 and I'm guessing requires a JB bootloader to flash. So my question is, is there a pre-rooted rsd package to get back to 4.2.2 so I can flash miui or do I have to flash back to stock, re-root and re-flash a custom recovery? Honestly I'm trying to get back for stability also. Unless someone knows where a KitKat miui ROM is for our phone? Other than the "V6" tablet ui ROM. It isn't no where stable enough.

simplest route for you: install rsdlite, flash stock 4.4.2 which will upgrade you to kk bootloader. then install supersu from play store, then towelroot and root your phone. thereafter, use motocalypse to unlock bootloader.
after that you are free to pick and choose which rom you want to install. if you wish to install a jb rom, you will have to downgrade to jb bootloader. otherwise, you're free to install your favorite recovery followed by your favorite kk rom while still on the kk bootloader

You don't have to be rooted to flash custom recoveries, so just downgrade to stock 4.1.2 (there was no 4.2) and then flash a custom recovery for the old bootloader.

If meant for 4.1.2 kernel then use flash back 4.1.2 then when recovery reboots flash the 4.1.2bl rom. Which 4.2.2 ROM are you trying?
We cannot teach people anything; we can only help them discover it within themselves.

Miui. I'm gonna try the 4.1.2 miui and then after it boots see if it will flash the 4.2.2 ROM.
I can't get any jb ROM to flash using the flashback zip... I guess rsd it is
