Ok guys, I need a little help understanding something. I have heard multiple times that you can't flash a kernel and recovery separately and this is contrary to everything I know about Android structure. Is this something specific to Samsung phones or is this complete BS? I have owned only HTC phones before this one and every one had separate things you could flash independently: kernel, recovery, radios and roms (though obviously roms came with kernels).
There are clearly differences between HTC and Samsung because I never needed anything like Odin before, but I just assumed that was something people used until a custom recovery was created or ported and never used again. Is there any reason we can't have the kernels and recoveries on separate partitions and not have to be flashed together? I feel like I'm missing something here.
Thanks in advance for the education.

You should be able to we just don't have the option available yet. On the original epic we rooted by flashing recovery in odin and then booting into cwm and flashing gmsu.zip and we were done without changing the stock kernel. I do not know why we can't do it for this phone.

Didn't realize Q & A had been created. I just had to look in the browser to confirm you were correct because the XDA app doesn't show it.
Jerdog, feel free to move this over. I'd like to keep this conversation going and get some traction on this.

It is being looked into. It seems the touch is different from other phones. You could do it on the epic. This phone is using it differently. From what I understand it is a backup of the kernel and overwrites on every boot.

Just popping over from the Infuse, saw this question, so here ya go. This is a Samsung thing. Yes, recovery partition is simply just a backup of the kernel partition. The kernel is actually kernel + initramfs image. The initramfs image holds the recovery binary. So what happens is, the kernel bootstraps, uncompresses the initramfs, runs the init, and then depending on the mode of boot, either runs the recovery.rc (which fires up adb and recovery). the lpm.rc (off mode charging basically) or the init.rc which bootstraps the rest of the Android system.
Very helpful info Bozo. Thanks for the detailed response.

Can someone explain to me the pros and cons of switching to TWRP? I want to move to TWRP because it's new and shiny but I'm afraid about the part of the backups not being compatible with each other. Is there anything I need to know before I make the jump?

... if your going to use twrp and not switch back... its not really any different other than backups not being cross compatible... but so what if your stick to twrp.

Nope you can inject twrp after flashing any rom or kernel to retain the recovery...

It's not compatible with some programs like rom manager and titanium backup, but can be "injected" into all ROM setups. I stick with CWM because I love the way I can name my own nandroids from rom manager. That's a deal breaker for me if I can't.
I use TWRP on my Kindle because that was the method at the time. Like mentioned before you cannot rename your backups which can get really confusing. I see no need to use TWRP over CWM, and personally wouldn't use it if you had CWM already installed. It would be like taking a giant step backwards IMPO.

I use TWRP mainly because it's easier to navigate.

You can go into /sdcard/TWRP/backups/(ur serial number) and there will be a file folder that contains your backup all you have to do is rename it

Twrp is interactive, newer, a little easier to use as it is more straightforward.

If you rename a TWRP backup file TWRP will no longer have the ability to locate it. Or at least this was the case on my Kindle using the method described above.

Not compatible with MIUI V4
I flashed this recovery with MIUI v4 and went into a semi-brick. It kept saying install Aborted so I went to reboot to system and it froze on the samsung screen and even the charge screen. I also couldnt get into clockworkmod. I had to odin back to stock PLZ DONT INSTALL ON MIUI LIKE THE IDIOT I WAS You could semibrick
I keep reading about everyone using CWM EL26 recovery so my question is, can I odin that recovery over my current agat one? If not how will I go about it? Also my nandroid of my stock rom will still be available when switching recoveries or do I need to go back to stock, switch recoveries then do another nandroid? I am fairly new to samsung so I want to be safe.....thanks.
If anyone can help I would highly appreciate it. Thank you.

What is your end goal?
I'm totally new to Samsung too. I use HTC. But I got my mom a gnex and rooted it with a custom recovery to maintain it properly for her. Maintaining Sammy is different from maintaining HTC.
How do I get the stock recovery back so I can take the firmware ota? I dont see a firmware ota I can just fastboot or recovery flash and the gnex forums are a total mess.

Agreed - please be careful where you post as each device has its own builds.
I understand it's not, and wouldn't use any files for another device. Just saw this post on front page of xda app, and since my question was similar, I figured I'd throw mine in, too. Thanks though.
Edit: and my god, the gnex forums are a MESS because the diff carriers and unbranded etc.

Ugh, don't listen to any of these guys. Anyone with issues on either recovery simply don't know how to use them. Best advice I can give you is to NOT USE THE DARKSIDE CACHE OR SUPERWIPE with CWM 6.0.x.x.
They break your CWM installation. Other than that I feel the same way you do. TWRP is great but I'm just used to CWM and prefer it. It's been on all 6 android devices I've owned and I trust it. Hard to break old habits!
Also, use the steps in this thread http://forum.xda-developers.com/showthread.php?t=1926754 to flash your ROMs. Should be smooth sailing. Either I'm lucky and my phone is perfect or my flashing method is key but I never have any issues with any ROMs that aren't already established by the original ROM developer.

Funny thing is when the Evo came out we all used AmonRA and that was the recovery to have and I must admit it neva eva eva eva caused me a problem. Clockwork was the bad stepchild over there so I stayed away from it. So to me old habits are not to use CWM not saying its bad but I had it on my Xoom and my Epic touch but now they both rock TWRP and itz the shiznicks..... To each his own
Is this really a bad recovery to be using. I always used clockwork on my HTC devices and when i rooted my epic touch i ended up with agat. Would it worth going through the trouble of installing a new recovery to get clockwork?

Sooooo, is it worth keeping or should i go through the trouble of installing clockwork.
And if i use Odin lite and flash the gb kernal with clockwork i can them boot into recovery and flash whatever i want?
And one more thing. I have a usb jig coming in the mail. If i am going to be doing all that should i wait till it comes in in case i need it or is it simple enough that i shouldn't worry.

Agat recovery is good for touchwiz based roms. I have flashed many ICS roms and zips using this recovery.
Regarding your questions if you want to flash a new rom follow the instructions in the OP of that rom, don't over complicate things. I use el26 recovery to flash roms. I load that using Odin from PC.
Its good to remember kernel and recovery are combined with this phone. Keep agat. If you want to go to jellybean get el26 kernel by chris41g. Also remember you will have a new kernel and recovery after you flash something.

This is one of the best two ways to root. Easiest simplest and fail safe. Stay away from kits everything goes wrong, wifi and data can break..

Good morning,
I rooted with the method that edfunkycold suggested above. Like I said things have changed dramatically since my Evo 4g on the rooting/rooted front. So I am still considering myself a noob. I flashed TWRP instead of CWM as I used CWM before and TWRP sounded interesting.
Here's my issue and I have searched the internet to no avail. I want/need to do a complete nand backup before flashing anything but wimax is not listed in TWRP backup. Am I missing something? Please help.
Also, I know I can flash within TWRP from the list of compatible roms but are those the only roms available for me since I TWRP'd?
Thanks!
Sent from my SPH-L710 using xda app-developers app
Wimax? You don't have a wimax phone anymore you have an LTE phone. just reboot into recovery click on backup and create a nandroid keep in mind a TWRP nandroid can not be restored with CWM or visa versa.
Do not download or flash any rom through an app first warning I will share with you. Do not flash from listed roms in TWRP. If you don't find the rom in the XDA Sprint S3 Development Section do not flash it. Or you risk owning a 600 dollar brick. Find the rom and download it from its source. At first I suggest you stick to TW stock based roms. Until your comfortable flashing and using your phone.

No don't use any of those apps to download roms. Your risking it. Search XDA threads Sprint S3 Development Section only.
Do it on your computer or the xda app or Tapatalk app to find the correct threads.
