How do I choose a kernel? - Desire HD General

Hello. I searched the forum but didn't really find an answer.
I was until 5 minutes ago with the MIUI rom. I know the last kernel I flashed was the cyanogenmod kernel (which I used with another rom...can't remember which one because I flashed 5 roms in 1 day).
I wanted today to abandon MIUI because I was having problems with the display timeout...and some other things, compatibility with applications and details were not really good for me.
So I flashed now the rcmixhd, downloaded from rom manager. What kernel should I use?
And....is a kernel independent from the rom? Will a rom not work with the proper kernel?

*deep breath*
By going through the kernel threads, reading about them, seeing what others say then choosing a few to try, add them, try them, make a decision, keep one.
Just like your radio question and your ROM question it comes down to two things:
1. Your particular hardware capabilities - Some devices like some kernels better than others.
2. What YOU want from the kernel and how much YOU think it's the best one for YOUR situation / wants / needs etc.
Only YOU can decide what one YOU like the most subject to them working ok with your particular handset (this is particularly true for overclocking).
As a rule of thumb, if you're not fussed about over-clocking or BFS vs CFS etc. then what ever kernel the ROM creator advises.
Now please, pretty please, use the link in my sig to find more in depth answers as this question has been asked too many times already.

You don't pick the kernel, the kernel picks you.

Request to all Kernel DEVs

Hi,
I have request to all Devs that also compile kernels by themselves.
Please use ipfilter owner kernel module along with iptables. It is essential for DroidWall application to work. It won't make difference to you, but to many people it will and this little fact does matter when some of users choose to or not to use particular ROM. I know you're not getting paid for your hard work so this is a kind request, definitely not a demand. In the end, it will make your ROM more popular.
In 1.5 times I could always flash Teknologists Kernel, but now almost everyone customize kernel for his 2.1 ROM.
As far as I tested many 2.1-2.2 ROMs, only CM6 builds and Villain have everything needed.
Thanks.
As I have promised you, ChocolateEclair will have the requested modules. The update is coming tonight, in 2-3 hours or so.
Thanks, I've also checked Vanilla one and would welcome its default @691/176 kernel with this module if you could be so kind. Just one more compilation to make me (and others) happy
I will add it next kernel compile. Thanks for the hint.

The Best Rom for Note 2

Well I will tell you this I'm not a developer but I am experienced in roms, the rom that I found worth it all is Ditto note 3 as if you are looking for a Note 3 and Samsung galaxy S5 for note 2 (and their theme and all of their features), keep in mind that it has minor problems that can be solved if you search the forum (Agni kernel is capable to solve them). Not to mention it has more than 4 million views. Link to the roms Thread: http://forum.xda-developers.com/showthread.php?t=2504016.
They are also working on a new rom fixing all of their bugs which I personally am excited for, you can ask me any question.
This is a best rom and i'm used it. but my question is..May this rom have some issues, we flash some file to fix it?
Agni Kernel will fix everything

You only need to download and flash this file (Kernel): http://d-h.st/users/psndna88/?fld_id=36625#files Which is Agni Kernel it will make everything run smoothly
Here is the main page: http://forum.xda-developers.com/showthread.php?t=2311094
Dear junior member - don't make threads about best ROM. Ever.
I totally disagree with your ROM choice, but that's beside the point. Didn't you watch the intro video for noobs? DO NOT JUDGE ONE DEV'S WORK OVER ANOTHER.
Reported to mods because these threads are sooo annoying.
Mod Edit
"Best" or "Recommend" ROM / Kernel threads are not allowed on XDA.
Please test these things for yourself. That is the only way you will get an unbiased opinion,
and then, you can decide for yourself if it meets YOUR needs.

Going crazy - ROM and Kernel suggestions please

Hello,
I recently rooted my Galaxy Y and installed CyanogenMod 7.2. After spending time trying to get Google Play to function (I have tried different things and searched on here) but being unable to I decided to try another ROM.
It seems very hard however to get straightforward and comprehensive details on here for anything i.e. whether a different kernel is required, what the installation procedure is in terms of wiping and mounting things. There seems to be a lot of assumed knowledge when things are posted.
So, can someone please recommend a ROM or ROMS with links to precise instructions on installation. I'm looking for something stable, quick, clean and customisable. Things that sound like they might suit are AOSP, EVO and Oxygen.
Thanks in advance.

Best Rom for note III

I tired from flashing the roms every days cannot find stable rom to stay with
can you share with me everyone here which rom you use now and happy with
Firstly, flashing a rom everyday isn't going to help with stability issues, and sometimes you will have scripts left over from previous rom that messes with new rom. You need sometimes 3-4 battery cycles to see if phone is stable.
We don't know what you're using your phone for... but generally it depends if you want stock rom experience or AOSP/CM.
Generally speaking, sticking closer to stock will be more stable because less modifications done. But current Lollipop isn't the best most stable android either.
With that in mind, go to http://forum.xda-developers.com/galaxy-note-3/development and find some stock (TW based) roms to try out. Make sure you do full wipes to clean previous rom (include wiping system).
*PS - it's not a good idea to ask people what's the best rom (and actually against forum rules). It's too subjective. Same with stability. How I use my phone and how others use it will also determine how stable the phone reacts, etc.
Good luck!
Best rom threads are frowned uppon and are usualy closed within hours.
But as said before try a rom for more than a day.
And make sure you wipe caches and such (also mentioned in almost every howto)
Try factory reset, and make sure you have the correct software for your hardware. As there are like 8 different types of Note3's...
And as in the nice post above this one Lollipop isnt all that stable.
Just get the rom that has what you want and test it for a week or so. and then for stability issues go to the forum thread you got it from and read up. As it might have a solution for your issues.
I would add to the above only this - Read the thread BEFORE you flash and make sure you understand the steps to follow AND what the issues are. Nothing worse than someone posting on page 10 of a thread that they have 'X' problem when it was dealt with on page 2.
Read many times, flash once is the best policy

I see a pattern emerging - lack of guides

Hello! This will be a quick post about how it was good earlier and how it can be better today, so please, stay with me.
I've been using Sony's for a while now, starting with small and cute Sony Ericsson k510i, then k550i, then wt19i (LWW), and then Xperia SP. My "flashing career" started after I've lost warranty on my k510. At that time there wasn't a lot you can do to your phone - there were several official firmwares, various customization options, and a lot of custom patches. No competition, one latest official firmware, a big library of patches that you could port to your device, if someone didn't do it already. The only competing area were a lot of graphical patches, but you could compile them together on your phone. Like today, if you were doing something wrong with your phone - you'll get a brick and it's your fault. But for every device there was an instruction, a beautifully crafted instruction on what to do and how to do everything, step by step. Almost every thread included a complete set of links to get you started. If you needed to flash a customisation after installing something, there would be a link on how to flash custom right there.
Today I have my XSP and try to do something to it. So I open one link (non-sticky, needed to bookmark it), see a lot of ROMs, part of which are no longer maintained. Finally open one of them based on performance rating, and see that it needs some kernel. So I go to kernel list, and see that it can't be flashed without recovery. What recovery? One specific recovery, because another one can't flash it. Now how do I flash recovery in the first place? I need a manual for that. Now I go to kernel and ROM page and see that no manual is available for them, too. So I open main device page and don't see any manual, so I open a sticky thread. And guess what? I don't see manual there. And that's when I start a new thread, type my problem in, and see a non-sticky thread with last post made 2nd of May 2015, and no pages link to that thread at all.
Is that how it goes this days? A newbie comes in, spends whole evening, opens 10 tabs, and still can't find anything relevant? I think we need to do something with this, revisit old threads, compile a new one-for-all guide, or at least a list of guides. And stick it, so people can actually see it. Otherwise there will be small closed community of those who already can develop and flash, and all the others who either got brick or is afraid to get a brick. Thanks.

UPD: And then I see that the kernel which I almost decided to flash is closed and all developers migrated to another one. I'm talking about tangerine and helium. Again, no info in the first post. And main developer openly says to users of his work - if it didn't work for you, don't use it. What's wrong with you people...
I'm deeply sorry if I offended somebody with my previous post. I'm happy that you guys do such amazing things with this 3 year phone. But damn, FULL INSTALLATION took about 10 minutes, counting PC reboot into linuxes to get fastboot working. In case someone struggles like me, use CyanogenMod instruction to get to Cyanogen Recovery; download TWRP Recovery, ROM of choice and GApps of choice; place all three ZIPs onto your sdcard; go to recovery, flash TWRP, reboot into TWRP (by pressing volume rockers while loading), do Wipe - Factory Wipe, flash ROM, flash GApps, reboot to normal. Wait for about 5 minutes (black screen is normal, there will be dots flying after a minute or so to keep you entertained).
Yes, It's that simple nowadays, so why bothering typing so much? I was in that situation with my SP, too, but if the are so many answers to these questions and so many threads... "You have to read" is the answer! A lot! It's for your own good, trust me. Now I can do anything I want with my phone with nohow! So a little reading and searching here and there is just positive experience for you. Don't complain, the people here ( well a part of them) are hardcore coders or themers or whatever. You can't just ask them to tell you all the stuff. If want help I'm always available.
Thank you for linking to my very dusty and lonely Flash ROM guide hahaha
No you didn't offend anyone at all. The guides are actually there, like how to use Flashtool, how to unlock bootloader, how to flash recovery and everything, it is just that they are buried deep with time as the development goes. The thread are there, in the General section and are awaiting to be searched. Though some are outdated, some are not and you can benefit from there.
Some searching will normally do, but if it didn't, just ask in the threads, someone will probably answer to you!
I always have my eyes on the General and Q&A subforums of the Xperia SP, and I will usually respond to a help-able problems. So if you have any problems, feel free to post in the Q&A subforum, and if not me, someone will help you. If there are nobody, don't feel offended. Maybe people don't know what to help or suggest (but lets just hope that is not what it will be )
About recovery, PhilZ and CWM is way outdated, and its time for everyone to make TWRP as a standard as it is a still updated recovery. Cyanogen Recovery in my opinion is crap as there are far too less feature plus, it enforce on signed flashable zips.
About the thread on Tangerine, the developer said dont use if it doesn't work is because of the norm of the Kernel. The kernel is made by using an AnyKernel template, hence render support for almost all Lollipop ROMs. Since ROMs can be updated and all ROMs have different sources, a simple change in the system part can render Tangerine unsupported, and the developer cannot do anything (definitely his choice, please respect that) to only fix the problem on one ROM which could possibly break support for the majority of the ROMs! This also appplies to Helium. Therefore, his words of "dont user it if it doesn't work" has a meaning, and it is not something to degrade new users and so.

Thanks for the answers and offering help, happily I was able to install my ROM of choice and it still works flawlessly, I was even able to squeeze 20 battery days from my old XSP.
Thinking about it, I start to understand why that dev answered like that. I was a python dev in the past and know how one feature can kill two others. Just in my head there is one current linux kernel, and all things that are developed should work with that particular kernel. Kernel comes before OS, if you will. Isn't it the case with ROMs and droid kernels?
About TWRP and reading: I honestly did read a lot of info before doing something, because it's my only phone these days. But it's so hard to find information on whether something is deprecated or not. As a new user, you wouldn't just google "is this deprecated and no longer used?", because that search will not provide any info. That is why during that evening and following morning I lost count of how many times I just shaked my head asking which recovery/kernel should I use and how do I install it? Latest being the easy one, because I already found TechnoSparks thread by that time.
In case anybody is interested, I installed Candy 5 on default kernel. But I still don't know if installing android 5 on a kernel used with android 4.2 was a good idea. It went well, however.
