Back up kernel - T-Mobile Samsung Galaxy S II SGH-T989

I was wondering what is the easiest easy to back up a kernel for our phone? I want to test others out but still have the stock kernel incase I need to send it in to Tmobile. Thanks

Don't worry about that, you can easily restore the phone (ROM, Kernel and Recovery) to Stock (Factory).

Also, to be absolutely safe, do a backup after you install Clockworkmod, then later you can just restore the backup and flash the stock recovery.

Lol. Why don't you just save them on to your SD card? On mine i have like 3-4 different kernels along with the stock just in case i feel the urge to do something stupid to my phone.
Kernel zip files only take about 5-6MB max anyways.

I'd also like to point out this is the development section of the forum.
This is not the forum for questions of any sort.
Please refrain from posting in this section unless you are a developer releasing something you built.
Thanks!

Neldar's sgs kernel flasher on the market can make flashable backups of your kernel. Haven't tried it on this phone yet though.

Not sure why but the .tar file is followed by a .md5 extention, so I just removed it and it became a .tar, just for others to know, thanks
the md5 extension is so you know it hasnt been messed with, and so you know the download is not corrupt...
odin flashes md5s and checks the downloads...
What would be the benefit of flashing this versus your other similar kernel? Sorry if this is a stupid question....
Thank you so much. This is perfect. Do have a question. Does this have a new version of cwm or the same one from yesterday? I ask cause the back soft button wasn't working and the storage mounts were reversed. Just checking to see if that has been fixed.

It is the same just without root and busybox. He made it for those of us that prefer having root controlled at the system level versus the kernel. You don't lose anything either way. If you use this you have to make sure you are running an already rooted rom. There is less conflict by doing this since most, if not all, roms are already rooted.

Once again thanks for you help. One last stupid question before I retire from stupidity, but how do I know which way I am rooted? I thought the only way to root was FROM the kernel. I ask because I'm specifically on midnight rom v2 and have no clue which way I'm rooted.
Is there any way someone could upload a mirror to a different site? I'm wanting to flash this but I'm at work and my company is blocking the site that the link is for. If you can that would be awesome if not, no big deal. I'll try and get it when I get home.
Edit: Nevermind. Managed to get it from my phone.
I can up it to megaupload if that helps Tiffany.
Link deleted.

Yes you will keep root cause the rom is rooted. As long ad the rom is rooted the kernel doesn't need to. be.

Just curious, if someone has flashed chris' previous kernel, what benefit is there supposed to be? Is it not the same stock kernel with some tweaks? Especially if you're concerned with losing root. Not singling anyone out, just curious as to the rationale.

Because kernels that have forced copying of root & busybox cause issues when you start using complete custom ROMs because they overwrite files that are already included. Plus if your including a custom recovery, what the point of including root, etc when the user can now flash what they want?
Also, Chris, the recovery you have included in this won't mount the internal storage or even make a backup to it or recover, it only wants to use the external sd card and since I don't use one because of the delay it causes coming from sleep, I can't do anything except test flash stuff
I flashed this around noon and once my phone rebooted, I updated my 'profile' under 'about phone'. Everything seemed fine, an hour later...I had a LOS, rebooted and got it back, an hour later, same thing...LOS. Rebooted and I updated the profile again, it's fine for now.
Do we have to update profile every time we do a reboot??
Didn't have any issues when in stock.

[Q] question about installing roms

Hi all, this is my first post and i hope to take advantage from it.
I've done a lot of research in the android development forums. The first thing i did to my phone was to get it rooted. So far so good, i followed the instructions and everything went ok.
Now i want to install a ROM. Thing is there is a lot of terminology i do not quite understand and i want to know for sure how this process is done correctly. In theory i know how to install a ROM but some disclaimers keeps me from doing it.
The main question here is, my phone has to meet some prerequisites in order to install a ROM? I mean, the android version of my phone, baseband version, kernel version and build number necessarily need to have the same characteristics from the ROM i will be flashing? For example, Team Kang's Juggernaut base band version is T989VKID mine is T989UVKL1, the android version is 2.3.5, mine is 2.3.6 and so on. That basically is it. I do not want to mess up my phone but at the same time i wanna enjoy those great roms.
Thanks in advance and i wish a happy valentine's day to all
Download ROM manager. Pick install from sd card. Wipe data and cache. Pick the ROM you downloaded. Just make sure you only install roms from this forum
Sent from my SGH-T989 using xda premium
The answer to your question is basically no. Roms don't change your baseband. So that doesn't matter. If your on 2.36 and you install a 2.35 ROM you'll just be on 2.35. But in the case of a kickass ROM that would be just fine.

instead of using rom manager, I would suggest doing everything from the CWM recovery itself. The manual way is always better and you encounter less problems along the way..
i.e. backup/restore isn't complete. didn't wipe everything clean... etc.

Yeah that's what I do, besides I hate how rom manager saves backups on my internal memory
Sent from my SGH-T989 using Tapatalk
I could be wrong but I think the last version of CWM wont let you make backups to the internal but you can flash from the internal. But the newest touch version that just came out a few weeks ago does have internal suppoert for backups so you have to flash the latest one. And I would listen to them when they say not to use rom manager there are far too many problems with it. Also the latest version of juggs is 4.1 and that is 2.3.6. I would use that one. Good luck

Yes i hope that newcomers take the time to read everything carefully. Hey i got a question... This is the very first rom i flashed to my phone. If i want to switch from one rom to another, i just cant flash it over the current one right? Phone might brick? What do i need to know before flashing a new rom to my phone. Thanks

You normally have to do a full wipe b4 installing a different ROM.
Chk out this site (galaxys2root.com) it gives me a lots of EASY TO UNDERSTAND info when i started playing with ROMs.Currently i am on my fifth ROM .
Yes do full wipe, Clear caches and do a nandroid back up first thou and make sure after flashing and re booting to let it sit for 10min

Where to begin?

Hey guys, im coming from a Galaxy Nexus, so all this is pretty weird to me. Usually the kernel is included with the ROM, but it seems like you have to worry about your kernel here. Then you have to worry about if your recovery partition has been wiped.
And the dreaded EMMC bug.
So im running FF18, and i need to root and install a custom ROM.
I dont have Kies installed on my computer, but my device registered in Odin.
Can someone give me a run through on what exactly i need to flash?
If you guys have a TWRP recovery port instead of CWM5.x.x, id love to have that.
Or a CWM touch recovery
I regularly change ROMs, so of this FF18 bug is going to brick my phone sooner or later id like to know now
Sent from my SPH-D710 using xda app-developers app
TWRP is usually a no-no with E4GT, if you want a kernel/recovery use Chris41g for AOSP and agat or rujelus for TouchWiz based ROMs.
Whichever comes in a Odin flashable format with root.
alternate to that you can use sfhub's autoroot package to root your stock FF18.
And you need to read more as all/most of the ROMs come with Kernel.
If you use sfhub's Autoroot to add Agat's safer kernel you should be clear of the brick bug. Agat, Chris41G and sfhub along with the other developers have gone a long way to stopping the bricking from 'factory resets' and wipes. However many users who don't take the time to read the stickies, how tos and the OPs of the ROM developers still get caught by doing something that has been explicity known to brick the device.
As rovar said make sure you read the ROM developers recommended install method and follow it precisely using the kernel they recommend.
With some earnest reading (through entire posts) you will have loads of fun and enjoyment. The developers in this section are really good and pretty cool. Just do some searching and you will surely find what you're looking for.
Good luck and welcome to the E4GT.
Ive just given it a quick glance, and it looked a little similar to the EVO 4G days where you had to find a kernel to go woth your rom, so rhats why i jumped to conclusions. My bad lol
Ill take a look again for an odin-flashable stock kernel
Sad theres no TWRP. Oh well

Sfhub has the Odin 'One-Clicks' available (by far the safest for people new to this phone) and rwilco12 has a repository of virtually all the kernels and modems flashable via Odin or CWM. Check them both out.

Just read read read then when you're done reading do a bit of reading. Honestly it's not as scary as I thought. I don't know how you would hard brick one but if you soft brick it then you can Odin out. Make your backups. Wouldn't hurt to have a full stock img or root66 img on your pc. Don't flash the wrong gapps like I did.
Back up IMEI and read some more.

Yeah if you go on flashing international roms, other modems then your asking to get hard bricked.

[Q] Anything i should do before i root?

I'm planing to root my Sprint S3 today using QBking77 video then i'm thinking to stay with stock rom but remove bloatware using Titanium backup.
But is there anything i should do before i start rooting? i mean do i need to backup the stock rom or anything like that just in case i mess up something? i saw a lot of threads about people looking for sprint stock roms to put it back to their phones.
Please let me know before i root my phone.
Thanks in advance.
You won't be able to do a backup until after you root.
Do anything before rooting. Yes. READ.
THEN, READ SOME MORE.
and don't try installing an international ROM.

READ, and when you have read it all READ it again. Make sure you know everything. Once you root, go back into custom recovery (CWM) and do a nandroid backup. Then you can start messing with it, if you screw up your can always restore that stock nandroid you have.
Then READ some more.
