custom kernel for stock .236? - Xperia Z1 Q&A, Help & Troubleshooting

hello everybody, I have a question its maybe a little noob but Im still reading and can't find the answer. is possible to flash a custom kernel in a stock rom without lose the camera quality? and if it's possibly which one is the best.
I trying to change governors in the stock kernel/rom but they keep reverting to initial values, in slim rom can stop the cores which is what Im looking for but the camera is very bad compared with stock.
thanks to all.

Flashing a custom kernel requires an unlocked bootloader.
Please read THIS if you're interested in unlocking your device's bootloader.

thanks for your answer but I got the unlocked bootloader, I'm asking because I can't find if there is any problem flashing a custom kernel on a stock rom, for now I'm a little tired of flashing roms so I don't want a bootloop again XD

If you stick with Sony's firmware, you must have a kernel based on it. Flashing any CM/AOSP-based kernels will conflict and bootloop.
Most people seems to use this kernel.

thanks that's exactly the kind of answer I've looking for downloading and try

[Q] Which roms and kernel should I use

Hello
It's been a while since I've got my htc one and I was waiting for the release of the stock 4.3 firmware before going into the custom world. Unfortunately, it's been quite some times now and I'm pretty tired of waiting.
So which rom should I take as a daily driver.. I'd like to be able to control tv (so I think I need to look into stock based roms?)
I'd also like to put a custom kernel and to be sure there is no problem betwen the rom and the kernel
So I was thinking about Android revolution and elementalx (no **** ahah) or can you suggest some?
is there a big chance that android revolution will be updated to 4.3?
(I'm still on 4.1.2)
Thank you!
Ps. What's s rev-on?
This thread's probably going to get closed because some people here are a little sensitive about people asking for ROM suggestions, but before it does... I LOVE ARHD and Elimentalx kernel lol. They're both super srabel, which on a phone like this with its awesome stock set up is a necessity for me... There's just no incentives for me to flash a custom ROM that's gonna be anything but perfect when stock is so close to perfect itself...
I get great battery life, performance, and stability. So that's my suggestion
And if you're talking about s-on, that means that certain partitions of your internal memory are still locked... You can still flash a custom rom, but you wouldn't be able to update your firmware or anything like that without getting s-off first.

You can update your firmware without S-Off. Android Revolution is stable because it's boring, just like stock. I'd recommend Viper Rom due to the vast customisation options, and it's just as stable. As for the kernel, stock kernel is best for most people. It's the perfect blend between battery and performance. Custom kernels such as ElementalX overclocked to 1.8/9GHz will give better performance but will drain your battery faster.
Everything can be done without S-Off. All S-Off is good for is changing your CID, MID, removing tampered from boot loader, and easily unlocking/locking without wiping anything or alerting HTC to your request of an unlock token.
the best rom is stock and the best kernel is stock. you sound like a man who will end up with a brick so i'd stick with stock

I flashed viper and messed around with it for a couple days and it was just a little too stuttery and I had apps force closing every once in a while... Tried a clean wipe, and still a couple problems.. Nothing huge or intolerable, I just value performance over the colorful theming and fun appearance settings of viper, but that's just my opinion and experience ... Everyone is different.
And I wouldn't worry about bricking... Being stuck on 4.1 sucks lol so if you wanna stay close to stock, arhd with stock kernel is the way to go. As long as you stay s-off and don't mess with your hboot (and always read read read before you do anything) you'll be fine.

Thank you for your reply ahah
Well so I'm like a noob because of my poor skills with english then...
I don't mind going with miui or cm10.. but I really love the remote control app ahh
Also, I want to do the s-off thing because.. I'd like to install ubuntu when it will be stable enough ahah
And i'd like to have the s2w function
Oh! I'm also very tired of the touch menu button on the bottom of many app... Dunno if stock have solved this tough.
Thanks again!

if you want no problems then you have to stick to stock kernels and rom.
android revolution is just another fancy name of a stock rom with minor tweaks Incorporated from other developers (such as APM). so thats the only rom which might fit your needs and has stock kernel too. actually there is nothing which is revolutionary in that rom... lol.
note : i am not a hater of that rom, but there is nothing i like about it too and it did sound funny so i wrote. anyways chill out arhd lovers .

yeah ok if the OP REALLY wants to do it and knows what he's getting into, then id recommend ARHD.
i'd recommend S-OFF first, then it gives options later
So Ubuntu touch will never be good on this phone :/ sad news ahah
Okay... I'll stick with stock roms then or arhd... I do like aosp roms too... But since nobody suggested one.. seems like I need to use stock to fully use this phone.. another sad news ahah...
Nofrills vs setcpu?
Anyway.. thank you then..

and if you want logo2wake then i recommend tbaldens 2.1.5 kernel
I'm surprised my thread isn't closed yet.. but I'm happy since the htc one world is very different from the xperia ahah
and.. well ahah I didn't s-off since the only reason for me to s-off was to get ubuntu someday :/
Anyway, such a big difference in rom size vs the xperia play ahah 150mo for xplay vs 1go o,o
Thank you everyone for your reply
what's for S-OFF ? is it mandatory for installing custom rom ?
what's kernel ? what's the function, sorry for noob, I've read quite a lot threads on xda explaining this, but I don't get it in a simple way ??
still confuse....

Stock rom

I know it is a little bit stupid question, but I am not sure and coz of that asking.
Right now I have stock rom and kernel.
I like it very much, but ther are some lags going on.
I didnt unlocked BL or installed CWM, so I want to ask where are the stock modified roms.
I have searched and looked in dev forums but without result. Or I am not sure for some specifics roms.
On my earlier htc sensation I had CM, AOSP, MIUI, etc...but everytime I am moving back to modified-improved stock versions.
Tnx

or you can just root your phone, clean the bloatware on it, put some apps for maintenance like greenify, and rom should be smoother and more battery friendly
best bet is to unlock and put zaiben rom on it, but it's your call what you want

Help. my phone's ram is full!

I have this problem for a while now but in the last few days it became more annoying
At the best time I have only 200 mb of ram and the rest is unavailable. I can barely write these thread because the keyboard keeps closing.
I have a c5302 and I use latest build 4.3 stock
I hope someone can help me because using my phone became really hard

Unless you're an advanced user, there arent any way to fix so. It is a DEFAULT problem on the stock ROM.
I'm familiar with flashing custom roms and cwm and kernels. That'll work out?

Flashing other kernel would deal some fix. But I am not so sure as I am not a stock ROM user. Applying Java heap modification might help as well. About the kernel, I recommend doomlord's or currently still maintained Williams Kernel.
Have a look in this index thread and find under the section Kernels to shed some light on other kernels.
WARNING: Do not flash kernels that are not designed for locked bootloaders when you are on a locked bootloader. I am sure you know the consequences.
But if you want to deal hardcore with this RAM problem, custom ROMs are recommended.

[Q] Difference between kernel and CWM/recovery

Hey there everybody,
I'm a newbie and about to flash my Note.
Though by now having a quite solid idea of the process,
I'm still stuck on this difference.
Is the kernel different to a CWM (like Philz)? Does the
kernel include the CWM (or viceversa)? CWM is the same
of modified recovery?
Is a kernel flashable afterwards , when a custom ROM
is flashed and working, but non satisfying in regards of its
performance (just an example)?
Also: what is a safe kernel compared to a kernel? A custom kernel?
Or.. safe kernel equals modified recovery? I'm really confused..
Thanks for your time
welcome
i understand your confusion, dont worry its very simple. I will explain it.
kernel and recovery are different things. kernel makes your device hardware run the software you put on it and recovery well as the name goes its recovery which lets you do stuff like installing zips, taking backups, doing wipes etc.
i hope you have understood the difference.
Now in N7000 i.e " Note I " the kernel and recovery are in the same partition thus every kernel has its own recovery bundled with it. So if you flash a kernel then the recovery that comes with it gets flashed along it.
to make it more clear take the example of galaxy s3. In GS3 you have to flash the kernel and the recovery seperately because each has a different partition. So there you can choose to have an X recovery for a Y kernel.
I am not sure if you can do so with the N7000 and as far as i remember the last time i tried it, it didnt work and the recovery remained the same even though i tried to flash a different recovery over it. I could be wrong though since i havent actually tried such in a long time.
About CWM, it is a modified recovery which gives your device the ability to flash custom roms which you cannot do so in the recovery that comes with the device. So if you want to flash custom roms then you root your device and install a custom recovery such as CWM or TWRP and flash the zip from it.
Every ROM comes with its own default kernel which gets flashed along with the ROM and thus we do not have to flash kernels seperately for each ROM that we flash but yes you can flash a different kernel for a ROM if you are not satisfied with the performance but make sure its compatible with the rom and supports it by which i mean dont flash a touchwiz kernel on a AOSP ROM etc. Make sure you read the description and instructions in the kernel thread and take a backup in the recovery before flashing anything onto the ROM. Be sure you understand what you are doing or else you risk messing the device
As far as i remember all the kernels are safe for JB and KK, it was ICS that had the unsafe/brick kernel issue but that was solved a long time back so i dont think you need to worry about safe or unsafe kernels anymore unless you are flashing an ICS ROM which i highly doubt you will.
A pro tip would be to make sure you read the instructions and a bit of thread pages to understand whats going on and what you need to do with whatever you are planning to flash
Hope i this helps you and not confuses you even more
Thank you very much
A big fat thank you!!

no difference, they are modified versions of stock android with different names and each has a community where they keep introducing features and support ROMs. if you look at the features list nowadays there is not really much difference between the two, the only difference I see is CM developed it's own kernel and recovery which can also be used on aosp/aokp based ROMs obviously
hope that helps

Mods or apps that make changes to system settings/files always require root. Try for instance custom launchers to add some features if you don`t want to root.

There are no other mod packs that I am aware of, though there is always Xposed, but it is in Alpha stage so if you're not a confident modder, probably stay away.
Why not use a custom ROM though?

Stock is better and more stable. Custom roms are fine, but a hassle to install and the easiest way to end up with a bricked phone. I have installed a custom ROM before, stock is a better experience.
Sorry, before I answer, my question was to find out your reasons and see if there was anything I could help you overcome. My intention is to help set your mind at ease, but given the reasons you've given, I apologise in advance of my answers seem like I'm just being a git.

I think that would be a sweeping generalisation and mostly the opposite of my experience. There is a nack to choosing roms though.

a hassle how? Download rom and gapps to sdcard, flash via recovery, wipe data, restore user apps. Don't forget you can't get OTA updates with root, mod packs and custom recovery so that's even more of a hassle imho.

I think that is another sweeping generalisation. I haven't ever seen anyone brick their phone with a custom rom.. Assuming you're using the correct definition whereby phone must be sent to the manufacturer for repair... The most I've seen is someone flashing a kernel or bootloader from the wrong device, or disconnecting mid-flash which can all be fine as stock too.. Though there was that time when cyanogen tried to downgrade the bootloader, though we tend to stay away from them anyway.
Maybe your reasons are born of a lack of confidence and that's understandable. The reasons you have however aren't really reasons though.
I would agree that it's mostly lack of confidence. I mean who would be confident in installing a custom ROM when there's always that warning about bricking and damaging the device. Why risk it? In my experience, it's not installing the ROM that's a hassle, but switching roms or returning to stock. And also having to factory reset the device constantly is very tedious.

The warnings are a general disclaimer so there is no come back on the dev. Ever wonder why some packs of nuts say "may contain nuts"? Its the same sort of thing.
There's no more risk flashing custom roms than flashing stock roms or OTA updates. In fact I think there is less risk. And by flashing mod packs, you're already taking the exact same risk as flashing a custom ROM, so I don't understand the logic.

Mostly people with none or very low understanding of rooting, flashing, adb and such are a high risk for bricking their phone.
The big picture is:
- make sure the fastboot drivers are installed correctly
- Enable adb debugging and enable oem unlock, both in developer options
- Unlock the bootloader in fastboot
- Flash TWRP recovery and make a nandroid backup
- Flash a custom rom and Google apps
- Optional flash a custom kernel
- Flash superSU.zip
- Reboot and thats it

No not at all. A while ago, I always installed custom roms, but I wanted to see how much can be customized with the stock ROM. Now I'm pretty sure I've done all I can w/ stock. I've heard Euphoria is pretty good also. Is that true?

Best way to find out? Try it for yourself. Also, returning to stock on a Nexus is the easiest thing, just a basic understanding of fastboot. There's a guide for that, in the general forum. Look in the sticky roll up thread.
That's the beauty of a Nexus, the simplicity of modification. The amount of development.

I cant comment on that because I haven't tried it or seen it recommended anywhere. That's not to say it's not good, I'm sure it is.
Best way to find a ROM in my opinion, look at the feature set and find one you like, then read a bit of the early pages of a thread them a few at the end to get a feel about what the users think.
Hopefully soon, Xposed will become stable and a whole world will open up to 5.1 users.
