Disadvanges of multiboot - Nexus 7 Q&A, Help & Troubleshooting

Hello there. I was thinking about putting ubuntu on my nexus 7. however I was reading that i needed a special kernel. So I wasent sure if I wanted to only run one kernel. Can someone tell me what I would be looking into if I decided to use multiboot?

(Help) Making and trying to port a rom for the first time for galaxy s

hi all, first of all i know this is a question and im posting it here and its the wrong place. It will soon be moved by a moderator. I get no replys in the i9000 Q&A or i9000 general so im asking here .
Ok so all my time at xda, i have been in the theming department and now this is my first go at developing. but before that, i have some really noob questions to ask. All i want to try is to port awsome roms onto galaxy.
1) first of all, if there is a rom for an another phone and you flash it, it doesnt boot up because our kernel for i9000 doesnt know how, am i right?
2) if so, can we make a custom kernel that knows how to boot stock froyo (nexus one) roms?
3)is it possible to change the entire system of our galaxy and make it stock so it is easier to port roms?
4) can i use a another rom (for i9000) as a base and then modify it to make my own rom. Basically use an another rom as a base?
And any other bits of information about roms is appreciated
COnsidering that cyagenmod stuff are straggeling to port it to galaxy s, with their very considerate experience and skills - I dont think you should touch it =)
but can i at least get answers to my questions
Thanks

2) i think the Problem ist the Recovery and that stuff we must change the whole system of this f******* "Samsung made" Android and i thin its to difficult..
3) Same at 2)
Maybe i could answers a bit of your question?
I want to try to make an AOSP clone for Galaxy S (just like gaosp is for spica users) that uses as less from samsung as possible. But that's a long journey, and I'm low on free time recently. From AOSP getting to cyanogen would be easy, although getting to cyanogen from non-aosp might still be easier. And there is also the possibility that the "Nexus Two" will be very stock-like with a hardware similar to our SGS, that would hopefully make porting current and later AOSP based roms and ports much easier. Until we find that out I don't think it's worth the investment in re-creating everything from scratch.
Eugene made a aosp clone but it still used twframework although everything was stock. The nptification pulldown didnt even have those tabs for wifi and stuff but when i was about to start theming it, it still had twframework-res in the framework foldrr, is the galaxy s touchwiz dependent?

Ubuntu on Android! Question

Hey guys, im just about to install ubuntu on my android phone, think im running froyo atm.
My questions is it requires what i remember hearing as loopback compiled in the kernel, which stock android has. Im wondering if samsungs kernel build has this also?
If so its just a case of installing it from shell and im away

[Q] Why should I put a Custom Rom on the A500?

Hi All,
I am a new A500 owner and a long time Viewsonic G Tablet owner; I know why I put a Custom Rom on the G Tablet (Stock Rom Sucked and VS dropped support). However after playing with my new A500 for the last week I really can see no reason so far to put a custom rom on this tablet.
The stock rom rooted and a few extras added/fixed like...
GPS Fix
NTFS Mount
Rooted
CWM Added
have really made this a very stable and very effective rom. I have been reading through the forum and I see a significant number of custom roms out there. I am sure they are there for a reason however for the life of me I can not determine why I would want to install any of them. I do also understand that I am coming late to the game on this tablet as I am sure these were probably developed to fix deficiencies in the stock rom when the tablet was first released.
So can someone explain to me why I would want to switch to a custom rom today given the stability and fixes available for the stock rom?
This is not meant to be a dig on any individual, group or any dev of these roms; I know these folks do an outstanding job and I appreciate every single one of them. However for someone new to this tablet it would be great to know what makes the custom roms better than what I already have with the stock/fixed rom I am running. I am currently running;
Android Version: 3.1
Kernel Version: 2.6.36.3
Build Number: Acer_A500_4.010.11_COM_GEN2
This is a sincere question and I would appreciate not getting flamed or bashed for asking. This is in the Q&A section so I am hoping this is the right place to get the answers I am seeking.
" The only way to learn is to ask... so I am asking "
To me I think everyone installs custom roms for all diffrent reasons. Each rom has its own benefits and restrictions. I have tried a few and always go back to stock.
Good luck and flash with great Caution

Hi Erica Renee,
Thank you for the quick reply... I was just not sure if there was a relevant issue that would persuade me to move from my stock rom to a custom one. I very much appreciate your response!!!

I'm coming from a Viewsonic Gtablet, and with the gtablet a custom rom was a must, here with the iconia I don't see any advantage to use a custom rom, Android 3.1 has everything I wanted. I only rooted it for ad-hoc support, but barely I use the ad-hoc, is only for emergencies, besides that, even rooting is not really necessary. Android OS backups all application settings, so each time I uninstall and reinstall an application, my former settings are there.
Just enjoy your Iconia
Frankly, I haven't felt the need to flash a custom ROM to the A500. I did root it to be able to use certain apps.
I have tried a variety of ROMs and kernels on my HTC EVO 4G, but that's because stock Froyo and even stock Gingerbread is boring. I think stock Honeycomb looks and performs great. It makes me really look forward to Icecream Sandwich.
I did add ADWLauncher to my A500, so maybe that's another reason why I haven't felt the need to flash a custom ROM.
i find myself in the same boat...
Running stock 3.1, rooted, cwm running - quite happy.
If you want to take it a step further, install Richardtrip's custom kernal and SetCPU and you will be amazed.

Hi entropy.of.avarice,
Thank you for the feedback, it is truly appreciated! I would not mind installing the new kernel as long as I knew for sure it would not break all that works well on my tablet right now.
Still on stock since I got mine - though I have since rooted - I'm not really making any use of it, only for file permissions and dropping boot animations onto the folder directly rather than through ADB.
I shopped around some of the ROM's floating around here and other that a few of the Touchwiz UI functions from Galaxy, [I don't even think it's supported or still available right now] there's nothing out there that would add to my experience in any appreciable way to risk going through all that [and back again] when I want to.
Stock is stable, runs smooth and fast and is supported if something ****s up and that is all I need - my life doesn't live and breath by the tablet so it's perfect for what I need it to be and what I need it to do.
I am using self-cooked official honeycomb 3.2 ROM (rooted, ad-hoc fix, etc)
with self-compiled 3.2 kernel, OC and apply different kind of fixes & patches.
Installing custom ROM & kernel is the act of tailor making your own OS.
It is why android is so attractive and additive.
Whay a non-stock ROM?
There are about as many answers to this as there are ROMs.
I have CWM / Recovery / Taboonay 2.0 w/ richardtrip's OC-able kernel (oc'd to 15000) and the tablet is Super Snappy! It has ad hoc support for tethering to my phone via WiFi, no random wake ups, Netflix with no broken cameras, Good GPS lock (after a bit of futzing...)
I was originally just gonna put 3.2 on there to experiment with and flash back after playing with it, but I got REALLY lucky. Did a FULL CWM backup and just flashed the ROM & Kernel over my existing ROM without wiping and...it just worked without me having to redo everything. So I just kept going..
I'd say at this point on the tablet no one REALLY needs 3.2, but a few of the modded kernels out there fix a number of sore spots that I wish ACER would just take care of...
I love our DEVS!
So...Up to you! But I currently LOVE taboonay 2.0 and the RT kernel...No issues at all for me...
(p.s. I still have two preceding backups of a couple of states of working 3.1 on my SD card that are 3 weeks apart that function wonderfully Just In Case! so, yeah..nothing really to lose by playing and testing...)

I rooted to gain performance. Taboonay and Richards kernel have given me a huge performance increase, no more lag.

Don't change unless you don't have a life and you want to spend all your hours figuring out what is wrong, have tried them all and stock is less head ake.

[Q] loop devices, does the stock kernel support them?!

n00b here to XDA and Android, 1st post, here we go..
Currently running international GN3, ROOTED omegadroid ROM with a stock kernel and trying to run linux on android(complete linux installer).
failing miserably and researched my list of probable faults back to no loop device support for my kernel.
My question(s) as the title so simply puts it is does the GN3 stock kernel have loop device support, if not is this something i could change myself? For my information how could i check?
Does anyone know of a kernel (for SM-N9005) that has this support? (I looked to no success[maybe im retarded])
If no then are there any ways in which i could help in the development of this feature for the kernel.
Also post if you have had any success with running linux ontop of android.
Any help would be greatly appreciated
Cheers guys!
I've spent hours trying to find a solution to this and as far as I know the stock kernel does not. And I have yet to find a custom kernel that does either. I would graciously donate some money to a dev that could build one
SM-N9005 stock rooted 4.4.2
Leankernel on jb worked fine for chrooted linux for me.

Kernel for ResRemix/CM12.1

Hi guys,
I would know if someone is starting building a new kernel for resurrection/cm12.1, 'cause there's only stock kernel, without oc/UV and new governors/tcp algorithms/schedulers.
I think there is no one trying this.
