Hello...
Sorry for my question, but I didn't find any answers to it.
The question is: What is the advantage of custom recovery? And, what advantages of custom roms?
Thanks for your attention and sorry for newbie question.
Umm custom recovery let's you flash custom ROMs on your device. Custom ROMs have many more options over stock, like 720p video recording, themes for Your status bar and icons, transparent widgets, more control ever settings and more options, etc. The list goes on and on, its endless. Custom ROMs are far better.
custom recovery is really just a GUI to make it easier to run commands you would normally have to do in a terminal or command prompt... makes flashing roms, kernels, wiping data, recalibrating your battery, ect. all much much easier...
custom roms have a lot more features built in, have some bug fixes and hacks that allow you to do things that you would not on a vanilla rom...
But is necessary a custom recovery to install a custom rom?

I believe that the stock Recovery will only flash ROMs that have an HTC digital signature. Whereas the custom Recovery will flash whatever you want.
So if you want to put custom ROMs on your phone the first step is to put on a custom Recovery.
The #1 greatest reason is nandroid backup.
It's like an image backup of the whole phone.
So if you make a nandroid backup, and screw the phone up, or do what you want, you can restore the nandroid backup and it will be 100% exactly as it was.
Yes custom recovery best function is certainly the nand backup. You can restore your phone to any instant in time exactly as it was at that point, down to every single file.
The last question. What is the difficult to back to stock rom from a custom rom/custom recovery?
I have seen many peoples here with problems to upgrade your custom roms (custom eclair rom) to a stock froyo when it come out.

There is no problem at all. You can flash any ROM you want in a few minutes.
Newb question, to which I have been unable to find the answer, but:
Is it possible to flash a custom recovery (which I assume must be done after unlocking the bootloader), but keep stock Android? Despite all the advantages of custom ROMs, my heartstrings are tied to OTA updates and pure stock.
My biggest reason for wanting Amon Ra's recovery is the nandroid backup as well.
Would a custom recovery/stock ROM still get OTA updates?

Yes you can have custom recovery but everything else stock.
And No you will not get OTA updates with custom recovery installed.
You can always just keep flashing custom recovery to do nandroid, then flash back to original recovery. Takes seconds on the PC.
From what I understood, if you were on stock 2.1 with Amon-RA recovery, you couldn't update to OTA 2.2 due to an error.

There is no difficulty in reverting, sinc ea custome recovery will allow you to flash anything.
BTW, you can also flash ROMs from your PC using the fastboot command line.
The main issue with reverting to stock is that unlocking the N1 bootloader voids your warranty. There is now a method of flashing a custom recovery without unlocking the bootloader. I recommend that method.
Hi,
I'm on stock 4.2.2 rom with root, custom recovery and franco kernel. What's the safest way to change kernel without losing my settings and data (and without breaking anything)?
I know that some kernels on the Nexus 4 modify files on the system partition. Does this apply to kernels on the Nexus 7 as well? If so, I'm guessing the best thing would be to reflash the stock system.img before flashing a new kernel. Would I lose root by doing this?
You can change custom kernel, you won't lose anything... If you want to return to stock kernel, you have to download factory image of your ROM and extract boot.img and then flash it with fastboot.

The safest thing for you to do is make a Nandroid backup before you begin. (Maybe get a copy of that backup off the tablet also to be extra safe.)
You can always go back to exactly where you left off that way if things go south.
BTW, you should have also done this before you flashed the Franco kernel, as well. Any future OTAs are now unlikely to succeed on your device (unless they do not include a kernel update, and that is somewhat uncommon). But having a full-stock backup allows you to roll back to that state, take the OTA, and then re-apply your customizations (e.g. Franco kernel).
good luck

I have used the twpr and I made a wipe cache+dalvik and I flashed the kernel and I didn't lose anything
As many people, I'm coming here from the e4gt. What I'm looking for is a stock kernel with a capable recovery repack that can do the usual cwm things and be capable to disable to reinstall the s4 mdl tenancy to reinstall stock recovery. It appears that shabby had his post locked with the recovery he had involvement in. I'm looking for stability overall. Sorry for being a newb all over again with a new phone.
I am not sure I follow your question ("...and be capable to disable to reinstall the s4 mdl tenancy to reinstall stock recovery.") No offense but just so we are clear, recovery and kernel are separate on the GS4 (each can be flashed separately). I don't quite understand what it is you are trying to accomplish. Are you trying to get back to 100% stock? Are you trying to install a custom recovery and/or root your phone? I would recommend starting with these threads for installing a custom recovery and/or rooting your phone:

Drunk posting. Used to recovery and kernel packaged together, like the e4gt. From what I've done, it appears I still have stock kernel with shabby's ou812 recovery. Yeah I know it's not called that. Attempt at humor because of my forgetfulness.

oscar, the S4 has separate kernel and recovery unlike the egt4. Take a look here
Using the stock rom for almost a year now and I'm mostly happy with everything I've done with this phone with rooting and Xposed modules except the fact that the only way for me to get functionality similar to LG's knock on is to flash a custom kernel. The knockr app is close but it sometimes messes with the power button.
Now, I don't want to have to do a factory wipe and right now I'm okay with triggering knox, but what kernel is closest to stock but has tap to wake support enabled? and is it possible to flash a new kernel without having to factory wipe? If not, how do I use titanium backup to backup directly to my PC?

I can't assure you that there is a Knock-On capable kernel, because no kernel on here features that officially.
You can flash a different kernel onto your device without losing data, it's not like the other fastboot devices where when you unlock the bootloader you will lose all your data. All you have to do is flash the custom kernel in Odin/flash it through TWRP (flash TWRP in AP slot in Odin and then flash the kernel zip in TWRP).
The only problem here is that usually people replace stock ROM because of the KNOX software and it gets annoying when it detects a breach in the TrustZone, so you'll need to disable KNOX using SuperSU and then TitaniumBackup freeze anything else that you may think is KNOX-annoying.
Being without a pc and being new to rooting, I had someone else root my Tab. It's only rooted. As far as I know there aren't any custom recoveries or roms for my device (SM-T330NU). When custom recoveries and roms become available I would like to start experimenting with this side of Android. My question is, what is the most strait forward way to go about flashing a recovery and then rom? I already have Rom Toolbox Pro installed on my Tab. It appears to have everything I need. Is this sufficient for my needs? Please list any drawbackswith this method. I'd like to avoid bricking my tablet. Thanks.

I've never used Rom Toolbox to flash a recovery or rom because there are so many cases of that causing trouble. There is TWRP Custom Recovery for your device. You can download either the img file (which you can install using a normal play store app called Flashify) or the tar file which you can flash using Odin. I would strongly recommend AGAINST using Rom Toolbox to flash anything, especially if you'd like to prevent against a surprise brick.
Edit: Just remembered you don't have a PC. Download the TWRP img file for your device and install using flashify. Worked for me
Almost forgot, you guys have a couple stock-based roms located here. From glancing at the OP, it's based on the stock OS but has a lot of under-the-hood improvements and most of the unnecessary bloat removed
