[Q] what goes first? recovery or kernel? - HTC Jetstream

hi.
what should go first? the kernel flashing? or the recovery flashing? does it even matter?
thanks.

Hi Guru_shastri,
I don't think it really matters. I am fairly new at this but from what I understand is that they are 2 different partitions so I don't really see how they would affect each other by order. The only thing I would suggest is having a working recovery first and doing a nandroid backup just in case the kernel installation goes sour.
Hope that helps.
Cheers bud!

thanks mate.
another question:
is there a difference between the insecure kernel that comes with the root process and the other kernel?
can i stay with the insecure or must i flash the other one on it after rooting?

Yeah probably would be a big difference. The insecure kernel was just made for the rooting process to my understanding. The actual DooMKernel has all the customizations, patches, improvements, and overclocking ability. I am running DooMLoRD kernel and its awesome bro. I've had no issue's what so ever and it runs so much better, I would recommend. Maybe DooMLoRD can explain this better if he is around...
Cheers!

thanks man,
i think i just figured out what crashed my device for so long...

No problem bro. Glad to help

[Q] Questions about new OS's and most things root and kernels... For Vibrant T-959

Hello everyone! I recently began contemplating rooting and doing custom installs for my 959, for something fresh and better performing, also seems my music player has been acting up recently and am really interested in something new along with voodoo sound... If necessary anymore ? Thing is, there are so many ways to root, and there are so many custom roms??? I don't know where to start or what to look for? I just want one of the better, stable, new custom roms available as of this date for the t-959. I search but seems there's no definitive answer? Just a lot of roms haha?
Also when downloading a rom, do I have to download like 30-40-50 kernels and add them? I see all these roms, kernels and update??? Is it just download a rom and that's it, am I making more of it than it should be?
I'm just really noob'ish, really confused, and really, really nervous! I can't afford to brick this phone, but I really want something new.
Thanks for reading, and I apologize for some of the silly questions I have asked .
I fell in love with rom flashing as it greatly improves performance and gives phone a new look. Especially since Vibrant isn't supported anymore.. I can't live without voodoo goodies=) Definitely improves sound.
Negative side of custom roms is it takes up some of your time.. Finding a rom you like, tweaking it.. Not too mention you might brick you phone.
If you decide so.. the most important thing is always read OP...
I used superoneclick to root. I recommend Bionix 1.3.1 as a first rom very stable though a bit outdated. After playing around with the rom, you can try different 2.2 kernels and modems. Then go on to gingerbread roms.=)
Extremely easy. I'd suggest reading some of my guides in my signature.
I would Odin
Then download a ROM (nothing else needed)
Download my option b update.zip
Move both to internal sd
Reboot into recovery
Click reinstall packages
Choose to install zip from sd, select ROM, reboot.

Thank you trailblazer and thanks s15....
Any roms you would recommend s15? I appreciate the starting rom you gave me Trail, I'm looking for something a little more up to date I suppose? I was looking at cm7 or Simply Honey 5.0 Revolution(JVR GB 2.3.4)? Something with voodoo already in it? Something pretty stable with a bit of features. Maybe a lil less lag than stock 2.2, better performance, audio and battery life as well?
Thanks so much again both!
cm7 in nightlies still, though seem pretty stable, i havent tried for a while. Lots of features though dont think battery too great.
Simply Honey is a good one, stable, lots of features, great developer support.
I'm currently on RevolutionRom 2.3.4, stable and smooth for me, only bad is itfreezes like once or twice a day. More of a sgs2 look which i like. Good battery.
FYI Flashing Gingerbread roms, you will need to flash gingerbread bootloaders to remove rainbows and see recovery ( theres a post on it)
Also GPS isn't stable on gingerbread.

I think I'm gonna try the simply honey one or wait till he does a final release?, as for the bootloaders, what do I do or go to there? Also for the kernels, do I need to download one for simply honey? Should I download one for it?
I seen some roms or kernel can improve wifi and signal? Is that true, if so point me in that direction hahaha...
Thanks so much bro by the way.
search for Vibrant gingerbread bootloader, it's flashable via odin..simply honey roms comes with bullet kernel & there's Simply Honey Talon Kernel build by simone201 =)
Thanks man, do you mind if I ask which one you would recommend (Odin or Clockwork?)... I stumbled upon this youtube how to called "Custom ROM installation tutorial for the T-Mobile Samsung Galaxy S (Vibrant)", and was just wondering if I can apply all his methods to SH 5.0? Sorry tried to link it but cannot due to my post count... Oh and when I'm done, how should I proceed with the new talon kernel?
Also if there's a new release of honey or the final release, say I installed this one... Do I have to do it all over again? Same wit kernels? Finally, do I need to revert my unrooted stock 2.2 froyo back to a previous version before gingerbread or any of this?
Thanks for your reply. I'm actually feeling like it's almost go time with this rom and kernel haha. Really thanks heaps!
D bootloader is only flashable by odin..you can read the OP for simply honey, what you need is all in there in d development area..flash kernel that works 4ur phone u decide on that wether bullet or talon..you can use sgs kernel flasher to switch bet the two..

One last question before I do this, I seen SH 5.1, but I seen it was for the i9000? Which one should be used? or the one you may recommend? Im looking for voodoo sound controls.
Thanks
EDIT:
Nevermind I read it will be up tomorrow... gonna do 5.1, this is pretty exciting as long as I don't screw anything up hahaha
i reverted back to stock firmware via odin and one click rooted my phone, factory wiped all data and now I remember after I rooted my phone I had unzipped file in my sd card and it told me that i can just delete it after I was done, well i did and then watched a video on clockwork that said not to delete it?
EDIT: Nevermind I fixed it, I just unrooted and rooted again...
So sorry for being a pain, I know you guys have better things to do.
3 questions and this thread is done... thanks for the help...
1. Does the market work on simply honey? Like can go in and search and download it like usual?
2. should I use odin to install 5.1 or cw?
3. how does the kb5 work? is that like default or do i have to flash it?
Thanks a million in advance!

From cm 7.1 to stock?

So i rooted by flashing, via odin, CF-Root-SGS2_XW_XEF_KJ2-v5.0-CWM5 over the stock 2.3.6 rom from kies update. I then flashed cm7.1 stable successfully after a nandroid backup of the original rom.
Now question is, if i perform a cwm backup, do i get back to stock rom, with my apps intact?
Another question about kernel: My kernel version doesnt have I9100XXXX in it, how do i pick a kernel version if i wana change/update my kernel with cf-root?
Thanks for the answers .
just restore from nandroid backup and everything will be as it was when you did backup
restore backup or reflash it
Thanks for the answers, any thoughts on the second question?

what kernel have you got? what kernel you want to have?
I managed to flash siyah kernel successfully with no crashes and what not. but one problem persists: when i start the phone everything is ok, but after i lock then unlock, display quality drops and everything becomes grainy, poorly drawn and somewhat pixelated. Anybody has an idea about that?
Should i just flash another kernel all together? what do you recommend with cm 7.1? I read somewhere about the stock cm7.1 kernel, where could i get that?
Seriously sorry for so much questions, but i think you can see how the issue is bugging me. Big Thank you for answers..

Recommendation + Question about kernal :

My Rom is Rasbeanjelly
first , i have to say its the most stable rom !
i have Paranoid and Rotbox and a its much better rom (without offense , just my opinion).
sure a less options , but too much options its not always advantage... so thanks for that.
question
I have a question now... i am still new on android area , and the developer wrote after we the ROM i need to flash a Karnel
name Trinty , i have no idea how to do that, where to download that karnel , and what's happened if I just flash the Rom
without the kernal (what I just did), or if I can flash it now without format my all system and do the process again...
thanks a lot guys.

You flash the kernel just like the rom, AFTER you flash the rom. You can find the trinity kernel in the original development area.
You can flash the kernel anytime, you don't have to flash the rom again, just clean cache+dalvik cache after you flash the kernel.
thanks, But i heard that all ROMS COME WITH A

Yes, all ROMs come with a kernel. Most of them come with the stock kernel from samsung. Trinity, ktmanta, franco and others are custom kernels, based on those from samsung but with some small modifications for performance and battery life.
I'm not an expert in android coding, not even close, but from what I understood so far kernels are some kind of drivers for the CPU, GPU and the other hardware parts like bluetooth, gps and so on.
Short story: with custom kernels you can overclock the cpu or gpu, adjust the voltages etc.
Trinity kernel is a good choice, flash it and dont chage anything.
Nothing will be wiped.
thanks... but if i dont know how to change my
GPU , CPU and stuff, that it actually will improve anything ...
i guess if i was an expert its should help me... but for some one that not understand what the advantage and disadvantage of each parameter
you recommended that also?

It really depends on what you want out of your device/ROM. KTManta lets you hand-set a lot of tweaks, but also benchmarks just a smidge slower than other ROMs, for example, while Trinity is fairly fast.

There's a thread in here somewhere about just that. Have a search at it, although there's really no one kernel that's "best"-- they'll all interact with your ROM of choice, so it becomes a kernel/ROM combo to look at. Personally, Carbon's stock kernel does best by me.
@samwheat Oh look, the person who complains about how atrocious his battery life is and how it's all the device's fault is back to try and recommend kernels and ROMs to users.
for a lot of modification, KTManta is your best choice I think.

[Q] e10i custom Kernel change?

Hi community, this is the first time I post something and maybe this is the wrong category:silly:
I have an e10i, I love it, and following the instructions of this forum I managed to flash custom roms and I'm extremely happy with CM7 2.2.2
But yesterday I read that this ROM supports nAa .32 kernel and I'm wondering if it's worth it to flash this kernel (since I read it is intended for newest androids) will this kernel improve the mobile performance with CM7?
And in affirmative case, how do I flash it over nAa .29? Directly over the old kernel? Should I wipe everything before? Is there any way to don't loose all my mobile data and settings?
In cas someone needs it: http://imgur.com/dOKFR6j

You can just flash it over the old kernel and it will work. You will only lose data if you flash different ROMS not different kernels. (ofcourse, don't do the recommended formats for the new kernel, because they destroy your data)
In any case, perform a backup in CWM first, so you can restore it in case anything goes wrong.
It will be a little bit faster, but on the other hand, you will most likely loose bluetooth capabilities, because the .32 kernel has a few issues with that. So just try, and if you're not happy, you can always flash .29 again

i9100 stock with root: which recovery?

Hi everybody. I've been using my i9100 for a few months so far, rooted but without recovery.
I need to flash some files now and i don't know what to flash for having cwm or any other kind of updated recovery.
Can you suggest me what to choose?
i've found PhilZ-cwm6-XWLSW-OXX-5.15.0-signed.zip, which seems to be the perfect choice but i'm afraid it won't support kitkat rom (and also i'm afraid it'll break my current rom by changing my kernel and taking me back to old superuser binaries.
Hope you'll help me, thank you so much in advance :victory: :highfive:

The zip you mentioned is for jelly bean, not kitkat. Here is the correct one for kitkat: https://goo.im/devs/philz_touch/CWM_Advanced_Edition/i9100/. Don't worry about superuser, you can always update the binaries (through supersu).
wonderful, flashed and it's working (i thanked you with the button as well)
just some more tips if you can: what are the best improvements that you would flash on the stock rom via cwm? thank you

Stock rom is pretty awkward, I personally recommend flashing SlimSaber + DorimanX for best stability, performance and battery.
