Hi,
I`m curious how/if undervolting (and overclocking as well) works on Nexus S after the ICS update. First, I must point out that I have a NS with stock rom, never been rooted, bootloader locked with official (now not working) recovery. The reason for this question is that the only reason I see for rooting this device is to undervolt to get more battery life. Btw I`m satisfied with the battery life I can get but why not to try to get some more ...
So, if I would root my device, what do I have to do next? Do I need another kernel? If yes, which are compatible with stock ICS? I want to stay on stock cause thats the reason I went for Google phone, the official updates without the need to flash roms ...
if the only reason to root just to undervolt...maybe there is an app in market can help u..
but if u use custom kernel...u can have more room to tweak it to ur best preference.
u can get custom kernel here: http://forum.xda-developers.com/showthread.php?t=1336529&page=91
but still in testing phase
for rooting...here: http://forum.xda-developers.com/showthread.php?t=1396959
Hi
Thanks for your reply, but I`m afraid root is always required for undervolting ... But thanks for the kernel link!
I'll start off by giving some background information. I ordered my Nexus 4 back in March and ran stock up until about July/June. Prior to the Nexus I had the HTC G2. I don't know how to root and and use custom ROMs and I have looked at the root guide for the Nexus but it's a huge barrage of information and some terms that I don't know what they are. However, this question doesn't involve rooting. I gave my Nexus 4 to a friend, who also has the Nexus, to root for me and use a custom ROM. In this process however, he did something that he told me to never do (I really don't know why..) and he ended up soft bricking my phone. He did that because my phone was stuck on the "Google" start up screen for over 40 minutes. Basically, he wiped the entire phone, I think. Due to some issues, we are no longer on speaking terms and he was the only person I knew who knows how to deal with rooting and custom ROMs.
Now I don't have the original back up of the stock. My question is, if I ever needed to send my phone back to Google for repairs or anything else, would I be able to somehow get the phone back to it's stock state?
Also, where could I find some resources that aren't a barrage of information? When I go to those threads like the Nexus rooting guide, it's just so much information and I get lost (I don't even quite know what a ROM is, my current interpretation is an operating system). Currently, I think I know how to update the ROM, I'm currently using Paranoid Android.
I apologize if this issue of mine can easily be solved with a search. I have googled this issue numerous times and I could not really find a solid answer.

Is the phone booting into PA? If not try holding the power button and the volume down at the same time. It should boot into recovery. If it does all you need to do is flash a rom "install a os".

Ohh yes, I should clarify. Currently the phone is working and I have it up to date on Paranoid Android. The only issue I had when updating Paranoid Android was that I could not use the kernel my friend had supplied me with (I think it was the Franco kernel). When I would flash the kernel, it would get stuck on the Google logo screen. I would have to get out of that by re-flashing Paranoid Android again and I've been unsuccessful in flashing any kernels. The main reason I wanted to root my phone was a custom kernel, to help with battery life.
My main question is that I wanted to know if I could ever get it back to stock (as to not void a warranty) if I were to ever need to for any reason.

which franco kernel, was it compatibke with your rom? i mean are you on android 4.3 and the kernel 4.2.2(or vice versa)? when you flashed the kernel, did you flash with the rom then boot up, or did you just flash the kernel alone? did you try redownloading the kernel, maybe a bad download? was it a jss kernel or a jwr kernel?

Yes you can.
Read the guides as slowly as you need to...stopping to research anything you don't understand...
Or just use those no brainer toolkits that teach you nothing.
And stick to stock until you know what's going on within your device when you do these things.

I'm not sure what version it was, I guess that might have been the issue. Would that have caused it to stay on the Google logo screen? I'll make sure to double check for that next time I try to do something.

Thank you for answering. Could you link a good starter thread for me? I was hesitant to use a custom ROM or even to root my phone. What compelled me to do it was the kernels extending battery life. Because I was so lost and felt overwhelmed, I had my friend help me but now we are no longer on talking terms so I'm lost.
Again, I wish to apologize, I know I should just look this up myself, but with the possibility of bricking/soft-bricking my phone, I want to get as much help as possible. Whatever small nudge, I will take.
Your questions can be answered by reading the stickies thread in the general section. Just follow the instructions to flash back to factory stock:
http://forum.xda-developers.com/showthread.php?t=2010312
If you flash a kernel and the phone won't boot, that kernel or version of the kernel isn't compatible with that rom or particular version of Android.

I hope it's not because he messed up your phone, it's not his fault that you trusted him to do it in the first place. If not, well nevermind.

It's very simple to get it back to stock. You'd just need to find a copy of the stock Rom (which I can assure you is probably on this very website floating around somewhere) and flash it in recovery like you would any other Rom.

Also keep in mind, custom roms usually come with custom kernels. So you shouldn't even have to worry about kernel flashing. If you want to preserve battery you should focus more on under clocking and thermal throttling...
You can find guides on here somewhere for that too...

It takes some time for the CPU to exit deep sleep. Are you on the stock kernel?

Ok, so you are on the stock kernel. Usually, installing a custom ROM helps with response time, due to tweaks. Try reading this, maybe it helps you understand:
http://forum.xda-developers.com/showthread.php?t=2367406
Try to use custom kernels it should help not just for the waking up but also the over all response of the device. There are really good custom kernels out there, Matr1x, Franco, Hell's Core, AK, and so on.

Why not? What are you waiting for?
Lets be honest here guys he was unsure what a stock kernel is and does not want to replace his rom on a phone made to have its rom replaced. This is one you leave alone so he does not do any damage to his phone.
OP the best thing I can suggest at this moment that may help you is to factory reset your phone and start from scratch. Maybe some corrupt files from all the installing apps and deleting them. This is probably the only suggestion outside of rooting it and joining the rest of us in flashing rehab....

Well said. +1 on the factory reset.
OP, if you ever decide to root and flash don't use a toolkit. Read up on using fastboot to unlock your bootloader and flash a custom recovery. That will get you on the right path to fixing your phone quickly, should you ever run into an issue.
Possible and weird solution was the flip magnetic cover case i removed the magnet and the problem is fix for now
Thenks all till ill root
Hey,
I'm thinking about putting a custom ROM on my handset, can anyone help me out and let me know the benefits of this and if it's really worth it?
Performance, customisation, more storage space
But generally at the expense of stability

Thanks for that,
If I did put a custom ROM on my S5, could I reset the device and it would go back to normal if I didn't like it?
Also in regards to the stability part, with the new update I have got on my S5 at the moment. The phone isn't what it used to be, they don't even display notifications on the phone without opening it.
Yea you can return to stock, but you can't do it by just resetting, you need to flash the stock ROM using ODIN, once you flash any ROM, resetting it will just reset that specific ROM, to change ROMs you need to flash the one you want
Factory resetting after updating from KK to LP is always recommended with stock, for the notifications, you have a load of lock screen settings you can look through, might find what you need in there - possibly in the security settings too, there are some that disable sensitive notifications when the phone is locked

Thanks for the help, I think I'll use a custome ROM. I've never actually used one since my days as an apple user. When I rooted my phone just to change the ringtone.
Is rooting on an android device relatively easy?
Or if anyone else has a good custom ROM I could use, I'm pretty new to this.....so something that isn't too stressful would be good!

It's very easy. You can use CF Auto Root for whatever android version you have.
keep in mind that rooting voids your warranty and will trip KNOX flag which leads to that you can't update using official methods such as via kies or OTA.

Hello Friends
I have been searching the internet for days on how to root the Note 5 N9208 dual sim and finally found something that seem stable.
DISCLAIMER: I am by no means taking credit for this root method, I am just sharing what I found because I know how hard the information can be to find on the internet. As you should already know, with flashing there is always a risk so you are always responsible for you own device
1. First you are going to want to enable OEM Unlock and USB debugging in the developer option.
2. Go to Samsung app store and get the CROM service app. (this is needed so you can flash custom roms, on some phones you won't be able to flash anything if you don't do this step)
3. Download Permissive kernel (from xiaolu) for N9208 with auto root: N9208-TW-Root (0909) .tar flash it with Odin3.10.7 (extract tar-file from zip, put it in section and flash AP)
At this point you should now have root, beyond this step will explain how to get TWRP recovery.
4. Official TWRP for Samsung Galaxy Note 5 DUOS you can found here ... (download tar-file, put it in AP section and flash with Odin3.10.7).
This information was accumulated by searching the web. My thanks goes out to all developers who help me to arrive at a root solution. If you, a developer come here and see a violation that I overlooked please inbox me and I will rectify it right away Thanks again
Thanks for the guide. Do you have more information on the kernel?

Sad to say, I didn't find much information on the web about the performance of this kernel. It just showed up as a way to gain root.
Not being about to accumulate any data on the kernel I kinda was back and forth in my mind if I should use it or not. after hours of thinking and really wanted root I decided to give it a go in a all or re-flash moment(nothing).
Turn out to be pretty good with no change in performance vs the stock kernel. Once flashed I saw superSU there installed and ready to go.
Now I was concern about the random reboots I heard about with other kernels but I have been using the phone for 3 days now and I haven't encountered any lags, no reboots, no drop of signals or calls. I have not yet installed any games on my phone so I don't know how it will be with heavy usage of that nature.
If you decide to give this a try please post any findings of abnormalities here. Thank you

Nice guide for obtaining root!
I already have rooted my Note 5 using the SpaceX kernel, but as some of you know this kernel has the random reboot issue.
What would be the procedure for me to flash this kernel. Can I just flash over the current SpaceX kernel or would I have to go another route?
Appreciate the help.

Cheers for the quick help! So just Odin flash this kernel directly over my current setup...will get right to it
Flashed the kernel and rebooted...all seems well. Now further testing and hopefully no weird issues like random reboots and/or deep sleep bug.
and We still don't know where it came from ??
but it Works
I seen it on a russian site thats all I know
but it works !!
Indeed...it's all rather strange No dev, no nothing...but it does work :good:
I got 4% battery usage in some 10 hours standby and that's pretty decent in my book.
Performance seems on par with stock kernel. Now for another couple of days of further testing to see if it holds up...(no random reboots and such).
I was at about 6%at 7hrs.....but I have one drive syncing. ..but before I had 15-20%....
and no reboots and I am rooted!!!!

lol yup, there is no data at all on this kernel as far as I can search. one thing I can say for sure is that its doing very well in terms of performance. I play games, listen to music, make calls on both sims, send emails and have dual whatsapp going all day. with all that activity I manage to get 13 hours out of the phone, I plug in at 18%. to me thats good. What do you guys think?
l think we have a rooted in 9208 dual sim that doesnt reboot and works fine
curiousty leads me toWonder Where it came from and whats been done to it
Guys, will this work with the hong kong version (9200)?
