[Q] help understanding kernels - Samsung Galaxy Nexus

Hi I might want to flash another kernel but gather it would be best to know more first. Firstly I get that it is the bridge between software and hardware.
If I flash another one that didn't come with the rom (I am using cyanogenmod 10.1) is it likely to cause problems? Also if it did would restoring a backup from rom manager return it to the former kernel or is the kernel on a lower layer which would remain unaffected?
I read that it is responsible also for managing processes/performance so if I flashed the stocked kernel would that then mean that the battery drain etc would be as if I were running stock android?

Search the forum or try it out. I guarantee you'll find the answers to your questions.
If you don't like it restore your backup and try again

Let me start by saying I've never flashed a custom kernel separately, one which did not come with a rom. But let me say this: since a nandroid takes a backup of the boot.img, which i believe is the kernel, i would think the backup would restore the previous kernel. As far as problems, I'd say you'd find that only by reading through the kernel threads, but it would seem that kernels would be optimized to work with many roms, undergoing updates as needed and having particular problems here and there. I say try it and report back. While I support reading and searching, and am aghast at how many posts repeat the same questions, i also think there are learning opportunities here, and sometimes repetitions teaches others, and digs out threads and topics we would not have otherwise accessed.

Body is mostly right. A nandroid restore will restore your kernel if you want it to. A kernel won't necessarily work the same on different ROMs though. Try 2 or three and see if you find one you like. I always end up back on the stock kernel myself, though I've previously had good luck with Trinity.

Well yes it did flash back to the original kernel because I had to restore a backup and luckily its OK.
After flashing the stock kernel it wouldn't boot up properly. Kept doing continuous force close errors on the lock screen after ages trying to boot that I couldnt get past coz they continuously popped up.

[Q] HELP!!!!

Hi, hope im posting in the right section.
i have had my desire since it came out , rooted it straight away , flashed loads of diffrent roms (from here) but now all of a sudden my desire has started crashing all the time and when i say all the time i mean about every 15 mins. I take the battrey out, boot use it for a min then when i next go to use it it wont do anything and i have to take the battrey out again and boot.
i have tried lots of diffrent roms it still does the same, i have even tried to run backups from rom manager and still the same. i have run antivirus still the same.
any ideas
thanks
It sounds like a kernel issue (too much undervoling or overclocking maybe, and some ROMs might not contain a kernel image), but first of all it would help us if you told us what ROM you're actually using right now.
Try to flash your sd rom.
If you use a2sd..partition again.
Full wipe again and flash you favorite rom.
If the problem still percist....Flash an official rom better old one 2.1 for no change to newer boot. Test the device if still freeze.
If everything ok, root again your phone ...partition again sd and then flash your favorite rom.
I've been having the same problem mate. Just flashed back to stock 2.1 and all seems fine now. Will reroot later this week and see what happens!

well tried everything so then tried flashing back to stock but it carnt find bootloader (using magic mem card)
any more idea's?
ps im using aurxtsense 8.0
i was thinking it was something to do with clocking as well.
mine seams to have calmed down now, it still couldn't find bootloader though when i tried to flash a stock ruu.
i formated my memory card and re-flashed aurxtsense 8.0 and it hasn't crashed since.
haven't tried doing anything since because i aint got time to sit and sort it out at the mo if something goes wrong again
Not sure what the means but you should be able to flash the ruu from HTC or if your phone is branded then one from the network. There's a like to them all in the dev section.
Can tell u though that I flashed back to stock and had no problems. Bit since rooting again its back. Even wiped my SD card and recreate the partitions. Doesn't seem as frequent this time though. I went straight to a hd Rom. It never used to happen on older custom roms and do think its something to do with the volting & clocking.

Unfortunately, we don't have anyone in the community who has inside access to that information. Some of our members are affiliated with Sprint, and so have slightly more reliable rumors, but even their sources have thus far been wrong if they quoted a specific date...
So I hope you understand that I'm not being a jerk when I say, we won't know until it actually happens (and this will probably always be the case)
That being said, this most recent leak (DK28) seems stable so far IMO, so it could potentially become our official update
ok im a total noob to all this stuff. i followed the guide to update my epic to 2.2. the problem is, that the camera, gallery, and a couple other apps dont work. Can someone help me? Should i go back to 2.1, if so, how do i do that?
EDIT: Angry rant removed, thanks to the mods for a quick response (and to the member who's post was removed: no hard feelings, I hope you understand)

Whenever flashing a ROM using either recovery, it's always a good idea to wipe the phone (as in factory reset - I'm not referring to wiping the cache or the dalvik cache, although both steps are also usually recommended)
If you used the odin method described in this thread: http://forum.xda-developers.com/showthread.php?t=861213
then you might have flashed the wrong tar - DK05 and DK17 both had the camera problem, make sure you have the DK28 file.
If you have the right tar, then you could have an incomplete download... I doubt that though, when that happened to me, my phone wouldn't boot at all. But you might want to redownload the tar just to be sure (double check the filesize after it finishes and before you flash, if it seems too small then it messed up again)
That's the best general advice I can offer, but if you'd like to provide more details about the method you used (especially a link to the guide you used, if it isn't the one I provided), someone here might be able to identify where you're going wrong
i followed the instructions from http://forum.xda-developers.com/showthread.php?t=861213. i didnt use odin, i just used the .zip method. it took me a lot of tries cause i kept getting errors. the second mirror link worked for me, but like i said, my camera, gps, gallery and some other apps dont work.
oh and everytime i try to flash again, i get the error.
It sounds like you're either starting from the wrong rom or not wiping the phone before flashing the zip. All of the zip updates I have seen require you to start from DI18 stock (root an clockwork seem to be okay in my experience, all other mods must be removed) - if you have installed any custom roms, your best bet is to follow the odin method using the stock DI18 tar - so you may as well just skip the zip methodand odin to the stock DK28 tar
And you absolutely must wipe the phone (again, factory reset - I suspect many people are just wiping the cache and/or the dalvik cache).

Odin flashing
I've got a quick question. I'm looking to move to a build using the DK28 information release and it requires that I update the pit and modem files on my phone using Odin. Do I need to flash a 2.2 rom right away or am I safe to boot into my current rom first?

Are you doing the strictly odin method (full froyo in a tar file)? Or an update.zip?
The odin method *should* include the modem and everything (and you use the updated pit in the same process) - you'll have to read the particular thread that you got the download link from, but I haven't noticed any odin tar files that required the modem separately
For the update.zip method, I don't know if it matters whether you flash the modem before or after applying the zip through recovery - I don't think either one overwrites the other, but that's a part of the process I can only guess about. But regardless of when you odin flash the modem, that's when you'll use the new pit file (the same as the odin-only method above).
As far as I know, the primary difference is that the update.zip doesn't inherently overwrite user data (but you'll probably have broken programs that FC all the time, which means a wipe is necessary, making this somewhat null). I prefer the odin method because it is a fresh flash of the entire system (I usually let it repartition as well - no one else has posted about that feature so I have no idea if it's a fluke that it hasn't given me problems)
Hope that helps
which is the best
so i have updated to dk28 froyo 2.2 i like battery life and performance can anyone offer info on which is the best rom for me or just some insight on which rom is the best overall
How do I stop running applications from starting every time I restart my phone?? I have the start up auditor but for some reason everytime I restart my phone the apps I have disabled keep restarting themselves and I have to go into the running programs and disable them manually. WTH?? Doesnt programs constantly running in the background kill the battery life?? How do I disable apps from starting?

How I understand it, especially with Froyo, you shouldn't have to kill programs in the background, if said 'background' process or service is working normal or efficiently. I still kill the DRM process when I reboot my phone, and not sure if it's still causing drain issues.
Also (someone else confirm this), I believe that constantly 'killing' certain background processes actually uses MORE battery, since it has to constantly restart itself. I've had a much more stable device *not* using auto killers, and just sniping one here and there that I know to cause drain.
Some reading material on GC, tho, in regards to memory management
Ignore me!

A lot of it is personal preference - this early in the game, the primary differences between the roms are going to be mostly cosmetic. So for now, the best advice I can offer is to try each of them and decide which theme you like. Regardless of how you upgraded, you had to use odin, so you have succeeded at the most difficult step of the process - and odin can bring your phone back to life if something goes wrong, so it's an invaluable skill to have.
In the meantime, keep watching the threads (quietly, unless you have a question that hasn't been asked already - we're working on cleaning up the forum to make it easier for everyone to find answers... but I digress...)
It's too early to be sure of any of the fixes out there - we have at least three separate fixes for the GPS issues; some people find success with one, others with another, and a lucky few don't need the fixes at all... so in summary, we can't say which is better or worse just yet, stay tuned and decide whether you want to experiment on the bleeding edge, or wait for these things to be stable and thoroughly tested.
And if you have any doubts, just stick with the stock DK28 for now
tl;dr, questions in BOLD.
Okay, after spending the entire night scouring the internet/this forum and starting from absolutely zero-knowledge about the Android OS, I managed to update my Epic to 2.2, and root the phone. Now, I'm kinda stuck as far as customization goes. I see all these cool skins and battery life mods and stuff, but they don't exactly offer any steps as to how to install them. Since I don't exactly know what file-types do what, I'm kinda shooting blindly at trying to update/install something "custom" onto the phone. So, my question(s) is/are:
What does the ROM do?
What does the ROOT do?
I know the root basically "unlocks" your phone, but that's all I know. The process of customizing the phone still remains a mystery. (that's the problem with following step-by-step instructions, rather than actually knowing what you're doing.)
I also don't understand the purpose of flashing a phone. Flashing, in my experience is to update something, like say a BIOS. But that sets the system back to square 1 as far as all settings go, in this particular example.
If I flash, with say Odin, after having updated to DK28 and "rooting," won't this make all the "customization" that I've done prior basically 'null' because I've just flashed the phone into a blank-state?
Sorry if these are questions easily answered by searching, but I just spent my entire sleep-cycle trying to find the answers to these questions, and managed to only get so far. I look forward to the answers On another note, I am now EXTREEEEMELY pleased with my phone. Before this evening, I was just the regular, old run-of-the-mill enduser. I liked the cool built-in customizations and all the apps and what not, but never dreamed of being able to customize my phone to THIS EXTENT. So, now it's something I'm very interested in doing..it makes my phone truly mine.

It depends on what you flashed with Odin. If you only flash a modem file, then your customizations and apps are untouched. If you flash an entire ROM in "tarball" form then not only does it re-write the modem but it also overwrites all user data. Think of the latter as resetting the phone to stock and works even if you cannot boot up.
When can we expect a custom Kernel with netfilters for wifi tethering?
n00b question.
If an SDK version is released (say, like, Gingerbread today), does that mean chefs could take it and cook up a ROM for ANY phone (say, like, the Epic)? Or do they need something else to do that?
Remove Touchwiz Launcher (consequences?)
Hey-- I'm using Quantum 2.0.0 ROM, and I never use the touchwiz launcher. Does anyone know if it's safe to just remove the apk? (TouchWiz30Launcher.apk) or is there other functionality tied to it?

I use titanium backup and am now running the DK27 froyo build by noobnl. My question... How do I restore my e-mail accounts to the phone everytime without having to re-type them in? I've been flashing a rom every other day on average since I got the phone and it's getting REALLY old.

[Q] Rooted my Dinc, now want to do more

Alright, so I rooted my Dinc yesterday, and there are several ROM's that I want to try out but am a little confused about a couple of things and the more I'm searching and reading, the more I'm getting confused. I'm probably over-analyzing it but I wanted to make sure before I venture on just to be safe. So if ya'll don't mind (as I'm sure these are total n00b questions that have been asked before):
1) My initial Nandroid backup - Does that backup the entire phone. So if I want to restore the phone to the original stock ROM and everything I can just restore the whole Nandroid backup and be good to go? My fear is flashing a new ROM, wanting to get the phone back to what it was stock, and not having a backup of it.
2) ROM's/Kernels. I thought a ROM included a Kernel to go with it, but I keep reading about people trying different kernels with certain ROM's. I'm really confused here so any info would help.
3) It is obvious that a lot of people have put in a LOT of hard work here. I just wanted to personally thank you all for the hard work and support, if it wasn't for what you guys have done and documented here, n00b's like me would be stuck with bloated handcuffed phones. So thanks a ton.

1). Yes, it does. If you were to restore it, it would be restored to the point you made the backup. That's why it is recommended before you flash anything, do a nandroid. It saves the headache of reflashing a ROM, or going back to a really old backup and losing anything you've done since then.
2). Yes, the developer will include the kernel with the ROM. People flash a custom kernel to overclock/underclock the CPU, better battery performance, among many other features. One thing to keep in mind: A Sense based ROM (HTC Sense) takes a Sense kernel, and an AOSP ROM (like CyanogenMod) requires an AOSP kernel. Don't flash an AOSP kernel on a Sense ROM (and vice versa), won't work and you'll need to restore your nandroid.
In the Development section, the developers are really good with explaining what it is they've produced, so you'll know what you're downloading, and if you are unsure, ask!

thanks again and happy rooting
While I am not going to hold your hand as there is plenty of information on these forums and the internet, I will steer you in the right direction. Since you are rooted, all you really need to do is download the rooted version of the latest stock rom. There are a few in the development section. The version is 4.22. After downloading you will flash this rom in recovery. Make sure you do a nandroid backup before flashing the update.
DO NOT unroot just to install the update. You will lose the ability to root hour phone for the foreseeable future.
Good luck

Ur not going to see much difference. The update dissapointed lots of people expecting a new look. Install a couple of custom roms if u want to have some fun. I am using the MikG v1.03 Rom with new sense incorperated and its waaaay better than the stock update we just got.

Pleat try to see this as advice and not being an ass.
Rooting your phone is really for being able to dig in to your phone and get all you want out of it and be able to customize more than the average evo.
What were your initial intentions for rooting? I get the draw to have free wifi tether but, that just happens to be one perk of it. Of course, there are the options of kernels and cpu clocking.
But, really the developers are attempting to bring the newest and most useful and functional features to the roms opening the full potential of your phone.
Aside from that, if you are unclear and confused about the process of flashing, you should really hold off and do some more research.
Go to the wiki page and read up! i spent about a month reading everything I could find on rooting, flashing, kernels, radios, prls, threads on roms and their issues and up sides. I knew what I was doing and what rom and features I was going to use.
Honestly, youtube will also be your friend. A few devs also post videos people have made about their roms including how to flash them. You should also read up on the results of mistakes made during flashing and how to fix them.
Get to know your phone and submit it to do your will!
Good luck!

Your apps were gone because you wiped data. Try Titanium Backup - there's a free version in the market that allows you to backup and restore, get the Pro key to avoid agreeing to the permissions/install of each individual app. The Pro version also allows for a larger number of backups per app, where the free version limits to one and when you make another backup it overwrites the first one. You can also freeze apps with the full version, but if you enable "Chuck Norris Mode" in settings the free version will allow you to uninstall system apps. There are other perks to the Pro Key, but I digress...
If you backup your apps & data, you can restore them on the new one. Whenever you flash a new rom, always wipe data, cache and dalvik (dalvik cache is under advanced in Clockwork). If you're simply updating the rom (ie to a newer version by the same dev, like Cyanogenmod nightlies) you can just wipe cache and dalvik unless otherwise stated in the rom. Whenever you flash anything other than a rom - kernels, themes, mods, radios, etc - do not wipe data.
If you don't know which rom to use, as long as you have a nandroid backup you can always go back to your setup that you like... so flash away. If you want to stick with something closer to what you're used to, try Myn's Warm TwoPointTwo... it's still FroYo. If you want Gingerbread/Sense, I've heard great things about MikG. I would avoid any rom that needs you to partition your SD card until you get your feet wet & know what you're doing.
Oh, and if you decide to flash the new radio update, don't pull the battery when you see the screen you've never seen before - you'll brick your phone. Just wait it out, and it'll take you back to recovery where you can then reboot normally.
(from... Evo/MIUI/Tapatalk)
Definitely look at Mik, and learn all you can about partitioning your card for APS2SD, you'll want that for the bigger ROMS, about flashing radios, very important to do that correctly, about theming, and so many other things that being rooted opens up for you.
Mik is great for sure, also kings roms. If you want something that is still htc sense there are many great developers and right now is the time because they are able to merge ports with the ota for the max performance for our phone while running gingerbread and having nifty new 3.0 sense features.
And maybe someday you will venture to the aosp world some day...

Please explain the ICS Recovery Warning

Alright, I'm no noob and I've successfully rooted and flashed several phones over the past couple of years, I get what we're doing - above a basic knowledge, well below an "expert". But it seems somewhere around FC05 I started seeing warnings about using the Rogue Repack to both flash ROMS and restore. I fully understand people were have major issues with touch recovery/ROM Manager, but this is different. This is what I've been able to pick from filtering through threads, it's a little tough to put it together because it's a few dozen post in many places. Please, in detail if you can, fill in the blanks.
1. Obviously, DON'T use an ICS recovery to restore a GB setup or the other way round. That seemed a no brainer.
2. Steady is advising people to NOT flash any ROMS using the FC kernals. I've waited and used the sfhub's one-click ODINs since EL26, but I found this interesting he's advising to not use it to go from FC06 to FC07, for example.
3. Some say don't flash an ICS ROM zip from ICS recovery, some say it's no problem.
I've slimmed down quite a bit during the ICS transition because, I knew I'd be doing a lot of flashing. So doing a manual restore is not too big of a deal. But is there, in an experts opinion, any perceived issue restoring an ICS nandorid in a FC recovery?
Data is formated differently in ICS, so it is best to just leave it alone. They say not to wipe data in ICS recoveries because of the format difference. Your best bet is to play it safe and use gingerbread EL26 kernel with CWM.
Thanks, and I get the difference between ICS and GB formatting, but are these warnings only for those trying to go back to GB? Or are you saying NO MATTER WHAT play it safe and if you must restore use EL26 (ie One-click back to stock/rooted), since the new ICS kernal would get flashed over it anyhow?
Forgive me for asking for a complete breakdown, but I'd rather play Devil's Advocate and get the info posted.
I would recommend ALWAYS going back to the EL26 CWM kernel. I attempted to wipe data from FC07's CWM and bricked my phone.

This has been regularly updated with advice and links as the OP is trying to get it stickied. It also helps those of us keeping a close eye on the topic to consolidate what we're looking at versus going through many threads.
As for flashing ICS ROMs there is a good link in that first post that should give you the requested breakdown. Hope this helps!
