[Q] Restore or flash a new rom? - Galaxy Note II Q&A, Help & Troubleshooting

well i think that maybe it is stupid but anyway.
I was at 4.1.1 stock rom just rooted and I made a backup(just in case) but since I found the SDS topic(I have the chip affected) i updated to 4.1.2. The first days my battery was more or less normal but I was studying and I didn't used it a lot so my believes were wrong, i have a potential draining and I want to flash the 4.1.1 stock rom and put the kernel such as perseus or red pill.
It is better to restore the last backup or flash a stock clean rom via odin?
Thanks!

[Q] Help with a rooted/flashed Galaxy S2

I rooted my Galaxy S2 then rooted Blazers Sexy Can I rom. I did a back up of my stock rom after I rooted it. Now that Sprint/Samsung MAY be releasing stock ICS, I may want to switch over to that. The battery sucks on Blazers rom. Anywho, if I restore to my stock GB backup with root and get the OTA update, am I doing any damage besides losing root? Could my phone be bricked just restoring my backup and updating? Also, if I decide to not do the stock update and keep my root, can I restore back to my stock GB backup then flash a new ICS custom rom with no issues? I keep wondering because I see how if you flash an ICS custom rom, you have to go back to a stock version before you flash another. I am just wondering if my backup is enough.

if you want to go back to stock el29 i would use sfhubs el29 1 click odin, then restore your backup....
if you want the stock system while keeping root just use the ff18 rooted 1 click as opposed to accepting the ota
if you're just upset about battery life but otherwise like the rom you're on now look into kobridge tweaks, and good practices for battery conservation- i.e. sync manually, set brightness low, etc... these could potentially greatly extend you're battery life

[Q] Quick kt747 kernel questions

I want to install a custom kernel on my Rogers Galaxy S3. I am currently running a rooted STOCK ROM. Which means I am still running Android 4.1.1.
I have been looking at this kernel here: http://forum.xda-developers.com/show....php?t=1756776 (I am using the Touchwiz JELLYBEAN version)
Here are my questions
1) I shouldn't have any issue using my device with this kernel right? I mean it's outlined pretty clearly but I don't want a nice $600 paperweight. I am running 4.1.1 on my device using a rooted stock ROM. (touchwiz)
2) WARNING: This kernel has updated WIFI and Bluetooth drivers. If you are going back to stock, you need to get those drivers back or those 2 devices will not work. Simply flashing a kernel will not do it unless it also flashs back those drivers (they are in "/system/lib/modules" folder).
What exactly does this mean? If I do a CWMR and restore back to the previous kernel, what will happen? What happens when I want to revert my phone back to stock? Do I just use Odin3 and load the stock S3 ROM and the kernel and drivers will be installed? Or do I have to do a special process to get WiFi and Bluetooth working again?
Also, this won't trip the flash counter will it?
I really appreciate your help guys, thanks so much .
Closed as per OP.

Thanks alot. Just what i wanted
Actually i have just thought about this and it does not include the zip. So this will not do the job.
Stock modules are in the stock nandroid (or ruu) these stock boot.img files fit the stock HTC modules. Modules are restored when a stock nandroid backup is restored
The stock 3.20.401 from Mike's thread is fully stock only in a custom rom install way. Only thing after the rom install that is not stock is the recovery.
So basically ive got to restore a Nandroid backup to do this?
Actually im guessing what you really want, you ask for the latest stock kernel. What's your goal with that ?
A custom rom has in 99% a tweaked kernel. A nandroid backup has stock modules + boot.img
So maybe you can point out what your goal is and i can give you the answer to that
Currently i am on Stock rom which is rooted. I basically want the phone in shape ready to receive any OTA that might come out in the near future. Im keeping root with the voodoo rootkeeper.
Ah oke and you flashed a custom kernel on it ?
Yeah i flashed the Tegra 4 one. Gotta say really good kernel, slightly disliked what it did to the screen though.
The easiest way to go back to full stock (modules + kernel) is indeed to restore the stock nandroid. Then its all stock, flash the stock recovery and you are also able to update official ota's (like upcoming sense 5)
Okay thanks a lot for that. Can't wait for that Sense 5 beauty, tried it on the One and certainly an improvement on the very good Sense 4.
Well i used an old Nandroid i had 3.14 software, factory reset, dalvik, then restored the nandroid. The Nandroid restored well except i was left with the kernel. Good thing is though the OTA still works as there is an update to 3.20
Ahhhh false alarm sorry. Me not thinking straight. -_-
The boot.img doesn't flash its self :L
Lol....solved ?
Yeah everything is good now thanks
Good :thumbup:
CASE CLOSED !

Cannot revert to 4.1.1 or 4.1.2 after 4.3 upgrade HELP

Alright guys I think I may be screwed here but I'm hoping someone can help me.
A couple of days ago I flashed a 4.3 stock rom from Samsung for my SGH-i747 and decided I wanted to go back to CyanogenMod for a bit. Today things happened with the rom that have caused me to want to revert back to the stock ODIN tar that I downloaded from XDA. It's a pre-rooted stock ROM on 4.1.1
I've made two nandroid backups (1 for CM and 1 for 4.1.1) both of which were before I attempted to flash the 4.3 rom.
I wanted a fresh start and restored back to the 4.1.1 and noticed I had accidentally uninstalled some important components via TiBu. So, as usual, I went to revert back to stock using Odin and the pre-rooted 4.1.1 build I downloaded. Only this time when I went into download mode I noticed a few new things I hadn't seen before.
In red was "Warranty Bit: 1" and something about the bootloader. I researched a little and I know it has something to do with Samsung's implementation of KNOX in 4.3.
My question now is what can I do about reverting back to stock 4.1.1 using Odin? Every time I've tried flashing it since seeing those new things, Odin fails.
Am I royally screwed or is there someone who can help?

Read around in the general section. you'll see that if you try to odin back to 4.1.1 bootloaders from 4.3 your phone will die. be careful. The developers here are trying to figure out solutions for this new update. I hear it's going slower than usual.
Well crap lol thank you. I'm on a pretty stable version of CM 10.2, should I just leave it until reverting to stock is fixed?

You installed CM10.2 after you ran the stock 4.3 update? i've heard of a few here that have done that. I'm not real big on CM builds; I actually prefer TW based ROMS so I'm gonna wait out upgrading (since I'm on a stable 4.1.2 ROM). If you've upgraded and you're running something stable right now I'd stick with it until the experts here find out more info.

No I installed the CM 10.2 M1 Snapshot before running the stock 4.3 upgrade but before doing so I made a nandroid backup while on CM 10.2 so I just restored back to it.
