[Q] Question about overclocking~ (Note 2 N7100)

Hey xda~ :laugh: noobynoob here and I got a few questions about overclocking, here we go:
1. Is it safe?
Just bought a Note 2 N7100 and got it in a bootloop [scared me senseless, thank god i fixed it]
2. Kernels?
Um what are kernels and what do they differ?
3.Are all kernels for overclocking compatible for my device/rom?:fingers-crossed:
Note 2 N7100 with Dr.Ketan's Custom Rom v10.0 android version 4.4.2 (I currently have my eyes on this kernel: http://forum.xda-developers.com/showthread.php?t=2001838)
4.What kernel do you guys recommend (in case this one isnt compatible or if you just know a better one):victory:
I'm open to suggestions, I just want whats best for my phone
5.If something goes wrong flashing the kernel is there a chance I get bricked/stuck in a bootloop?
already messed up once when trying to flash my custom rom, im afraid itll happen again
ThanQ :laugh:

The kernel, in the simplest terms, is the piece of software in the operating system that tells the OS how to use the hardware.
Custom kernels typically take the stock kernel and modify the settings, and/or add features and setting parameters (often ported from other custom kernels).

I don't know. It's your responsibility to make sure it's compatible. I know Samsung makes many different versions of their Notes and Galaxy XS models (for different carriers, different regions of the world, etc), so a kernel for one version of the Note 2 might not work with your Note 2.
Further, just like it is with computer processors, not all are created equal. After manufacturing, processors are tested sorted into "bins" (literally) according to how well they work. Typically processors are all underclocked below their potential to some degree. That way they're not maxed out and overheating won't be a problem. Since they're underclocked, that means they can be overclocked to their true potential, but how far is a roll of the dice. One guy's Note 2 might have a processor from a higher bin and stably overclockable to 1.9GHz. Or you might have gotten one from a lower bin, and all you can OC it to is 1.7GHz. OC'ing too far will cause glitches and crashes.

I can't help you with that. It's best that you just read up on the kernel(s) you want to try, and by "read", I mean start from the first post, and read every post until you've read them all. That way you know about possible problems and how to sort them out if you encounter them.
5.If something goes wrong flashing the kernel is there a chance I get bricked/stuck in a bootloop?

If you have a custom ROM, that means you have a custom recovery (TWRP, CWM, etc). From within the recovery you can do what's called a nandroid backup. It probably won't be labeled as "nandroid" (even though that's what we call it), but just a backup. This creates an "image" of your phone as it is when you run the backup. Store it on your SD card or PC (or both). If something goes wrong, you should still be able to reboot into recovery and restore your backup. Or, if you have a copy of your current kernel (custom ROMs sometimes have their own kernels, and might be available to download), you can just reflash the old kernel in recovery.

ThanQ
hmmm I guess ill need to read up more, I read on the kernels page something about needing a touchwiz based rom? what does that mean and how do I tell if my rom is tocuh based? As for that backup idea, that seems pretty useful, im gonna do that right now

TouchWiz is what Samsung calls its interfaces.

Installing New Roms

I recently purchased a photon Q, unlocked the bootloader and rooted it. All went well until I tried installing a new ROM. I've tried installing both Carbon and CM11 but with no luck. Thankfully, I've been keeping backups of my stock ROM so I'm still able to restore the phone and use it.
I'm currently using cwm 6.0.1.3 , and I had been trying to install the new ROMs via rom manager. I'll try to get more error details up Friday as that's when I'll attempt to install the new roms.
I tried installing the latest nightlies for both CM11 and Carbon.
Any advice or help would be greatly appreciated.
Thanks

CWM 6.0.1.3 doesn't support SELinux and so it doesn't support any KitKat ROMs (CM11 and newer).
Use TWRP or OR as a recovery.

I wondered if that was the problem. How would I go about putting twerp on my phone? Do any threads cover that? Would it cause an issue with CWM or would I have to get rid of that in order to install TWRP?
Thanks, by the way.

The TWRP page for the Photon Q goes over how to flash TWRP.
http://teamw.in/project/twrp2/137
Any recovery you flash will simply overwrite the previous one. Simply flashing TWRP as normal will just replace CWM.
Same with OpenRecovery, simply flashing OR over CWM will replace CWM with OR.
Let us know if you have questions. I like the fastboot method, but there was an app in the Play Store TWRP Manager - which I have never used, but should work fine.

Awesome! I replaced cwm with twrp last night. I'm going to try installing Carbon either tonight or tomorrow. Thanks a bunch for the help guys!

Well, it worked...sorta. i tried installing Carbon, but there seemed to be some kind of bug that didn't let the wifi turn on(along with some performance issues) and I have horrible reception at my place so that didn't get too far in setting up the phone.
So I installed the latest CM 11 snapshot and that's working great! Pretty awesome to be on the latest version of Android for a change!
Still want to try Carbon though, do they have more stable releases or do you just have to go out on faith with the nightlies?

I run Carbon as my daily driver, no problems.
Post in the thread if you have issues. As always, clean flash before reporting any.

I posted this in a couple other threads as well but since you guys are talking about it... do you think the Carbon is superior to the CM10/11/12 roms? I've found mine to be laggy lately. Maybe it always was I'm not sure.. lol but I was thinking of going to 10.2.1 .. someone on another thread said he did that and it was like having a different phone .. it was so fast.

Please quit cross-posting. You are severely diluting any community effort to respond to you by posting the same question in so many threads...
Truth be told, YOU need to make the decision for yourself. Take a backup of your current setup and try something new, you have nothing to lose but some time. If you don't like it, restore the backup you took (please please take a backup IN RECOVERY before making any changes).

LOL sorry lets not kid ourselves. There are 4 active threads since May 24 in this sub category of the Photon Q. My intention was not to spam-post, however given the slow movement of the forum I posted in a few relevant threads in the thinking that those who were active would have subscribed and were maybe notified Sorry if I did a few too many... for tonite I probably have had a few too many Coronas (Cervesa Mas Fina!).
This device is in a production environment. There is not much room for any downtime on the device so I do not have that luxury of playing with it. All these Photon Q's I would think have the same specs so there must be a general consensus or benchmark'ed result as to which ROM offers best performance with the usability balanced. I do need more of these devices moving forward.
Funny thing, I live within 50 miles of Blackberry's campus and they have failed us yet again. Their passport phone is a little more reliable and less buggy than last years Q or Z models, however I'm still lacking a row of numbers and a dang home and back key. When are they gonna figure it out! Just using the gesture/swipe to get to the homescreen doesn't appeal to me. You can't give me a home button? Anyway #offtopic a little.. but is there no general consensus or are they so close its difficult to pick a winner?

Have tried a number of ROM's carbon, PAC, Cmod, stock ICS, & JB.
Tried different flavours & unofficial versions.
I'm now happier than ever, running stripped JB - removed bloat ware & other obsolete APK's, plus added a few niceties using xposed framework.
Phone is fast - as in no slow downs & pauses, like I was getting with carbon & PAC, battery is unbelievably long life - using an xposed battery saver module, plus I added extended power menu options.
The main killer of all the other custom ROM's is the persistent Bluetooth error during calls. This is something that has been in the ROMs since Cmod wrote the first one, as all the other are built off of it.
If you don't require Bluetooth for calls, then go for it - personally I am finally happy with the JB stripped & tweaked stock.

Miui 8 on Mi 4C

Hi guys!
I installed yesterday Miui 8 alpha from here: http://en.miui.com/thread-295006-1-1.html
ATTENTION!
This will be locked your bootloader!
I tried the recovery image, but it didnt work. I flashed first stable miui 7 from eu.miui than got I drecly a system update to Miui 8.
Unfortunately it's still based on android 5.1.1.
Here are screenshots.

How is Battery life... SOT? Thank you!

I dont know. I didnt so much used. Now Im back to sMiui. But I think its not beter than sMiui.

I use xiaomi.eu version which doesn't lock bootloader. Everything works well...somewhat. Back camera got downgraded features (only 720p max?), front camera can still record 1080p. Battery life, SoT and RAM consumption are similar to 6.5.26. I enable the battery saver, though. Plus only some apps are allowed for full background processing. I'm sticking with it, next updates should be better.

I'm using MIUI8 for nearly 24 hours now and I'm quite satisfied. Have not recognized heavy bugs (not even small ones).
The battery life seems to be similar to MIUI7 builds and worse than CM13.1 from TeamSuperluminal, which I used over the past few months.

I've been using first version of MIUI 8 from the first day it came out, on xiaomi.eu and I haven't got any issue what so ever. I find it works well, no bugs on my type of use so far. The thing is I don't find a significant change over Miui7... Do you guys? Generally speaking. There are a few functions on sharing that are diferent but it isnt something you should worrie about to hurry up updating.
My suggestion for everyone is that if you are in Miui7 (whatever stable or dev version) dont feel you are loosing something without having version 8... it is almost an appearance thing only changes. I'm not dev so i dont actually know what changes in the inside code and stuff, just speaking over a consumer and tester view.
If there is some devs who can tell what important changes are made over I would appreciate.

miui 8 6.6.23 beta. full wifi usage

what i feel is xiaomi added new theme to MIUI 7 and brand it as MIUI 8.
Nothing significant, everything same as MIUI 7.

totally agreed, i had some overheating and touch issues btw

I'll wait Miui8 on android MM for Mi4c before installing that...

Hi! Please help me out
I will receive my new Mi 4c with the Bootloader Unlocked from the re seller , Rooted and with Multi language ROM.
Do I have to unlock the bootloader with the official method (which means flashing Cina Dev ROM -to re lock the bootloader- and go on with the Xiaomi's code procedure..) or it is possible to get all things done by choosing an unofficial weekly miui.eu international ROM and install it normally from the Updater app as soon I get my device but also be able to update it every week via Updater without issues?
My problem with flashing is that I don't have my laptop and the one I have now runs win xp.

If your MI4C is rooted you can install Flashify. With Flashify you can flash TWRP. Then you can download any desired rom and install that from TWRP.
No need for a computer.... unless you brick your phone at some point.

First, just see first if you can access to the recovery rebooting with Vol button pushed.
What's your rom version.

Hi! it's been a while since I made this post and I've changed the MI4C with a Mi4... thanks anyway! Best!

How to know which kernel to use ?

Hi guys
I have a old Moto g 1st gen (xt1032)
And been trying to get it running now but with not much luck.
The bootloader is unlocked and twrp installed and I installed a stock rom but it keep crashing about once or twice a day so I formatted everything and installed another rom can't remember the name right now but was comparable for my model .
And that won't get passed the black "android" screen
So been looking into it and people mention kernels but I haven't got a clue about them tbh so how can I tell which kernel I need or do they suit all ROMs
Can anyone suggest a matching kernel and rom
Cheers

I'm a lot really late but just a try a few different ROMs and make sure they say XT1032 or Falcon. ID crisis and Exodus are good 6.x ROM that are very stable. As for kernels, unless you really want to do some low level tweaks that require kernel intergretaion like Overclock, DT2W, CPU governer, etc., I wouldn't worry about it.
If you DO want a kernel I can't recommend ZERO Byte kernel by @BryanByteZ enough. Under volt/clock and over/volt clock, DT2W, it's got everything. Works great with Exodus

Sooo about that a good start is to flash the latest stock 5.1 then flash twrp and choose a 6.X rom (based on cm13) and that depends of your likes and wishes if you want a stable like rock rom i recommend AOSP+OMS 6.X/EXODUS/VanirAOSP if you want customizations there is Ressurection Remix,Dirty Unicorns and others, you just "need" to flash other kernel if you want more advanced features. This is just a recommendation for roms but lucky we have Kitkat,lollipop,marshmallow and nougat roms.

Thanks for the replies guys
I'm beginning to think I have a hardware problem on the phone.
I installed 3 versions of stock 5.1 on it last night
Eu,Brazil,and US I think they were they all install without errors
But only the Eu one boots up the other 2 stay on the "android" black screen.
The one that does boot us unstable though and crashes quite often .
That's why I thought about kernels and maybe it was that as I'm not sure if I need a certain one on my phone or any compatible one will do.

Well I already passed on that I change my bootloader to the one from BR stock 5.1 and now everything works fine. Try to change data partition to f2fs file system.

Anyone still have this phone?

Does anyone here still have this phone? only for curiosity
I just noticed that I enter the low activity device group
It's really a shame ... it's not a good phone, a newer rom would make it explode
See Ya!

Yes me I have one. I search in the net to find a debloat rom to go in. Can't find anyone even in XDA! It's a sm-g386w but if if found a ROM for sm-g386t I'll try...

Yep I still have my GT-18262 and I use it for experimental stuff only though but it was my first samsung phone...

I got it in my pocket in this very moment. (It's
a core G-386W. More or less a late model with better parts. 0.5gb of more RAM iirc
Really run smoothly in most conditions. Still love it. Only replaced it with a LG V20 (not letting go of that removable battery) for OS reason.

I still have mine works great for me I just wished I could update it so I can get some newer aps so at least I could connect my smart watch with it. the only thing I did was years ago installed rooted it and installed kitkat ( I think it was back in 2014) other then that haven't done anything but bought a new battery

Does Wi-Fi and cellular networks work? I installed CM12.1 on mine, everything works perfectly, except the Wi-Fi and calls/sms

I know I am almost 2 years late to the party but I will leave this for those who are willing to dive into the rabbit hole. I managed to build a "functional" lineage18.1 for the SM-g386W Afyonltecan and I am willing to share it as well as the source so that hopefully someone more knowledgeable than me will take the lead or help to fix the bugs so that we can enjoy this piece of history for few more years. Don't get me wrong, it is far from perfect and so far only worked on my device. I also successfully build lineage 16.0 and twrp 3.7.0 but they are too buggy to be useful as is.
