[Q] Is this recovery safe? - Samsung Epic 4G Touch

I recently installed the rom: http://forum.xda-developers.com/showthread.php?t=2285290
It includes AGAT_Recovery tREC_v0.3.5
I made a nandroid backup with it (it looks and functions identically to CWM). When I flashed back the EL26 ODIN one-click and tried recovery, the system image failed to flash. My question is: if I need to make a restoration with a system image created in AGAT_Recovery tREC_v0.3.5, is that image safe to restore with AGAT_Recovery tREC_v0.3.5?
Thanks for reading!

You must restore using the same kernel that you used to create the backup.

OK, so in every case the 'safe' recover is EL26 (Gingerbread). That is a different kernel than my current ROM runs. So basically, what do I need to do to nandroid backup & recover? Like I CWM failed when doing the above. Next time, are you saying that I:
EL26 CWM-->(flash kernel of ROM backup)-->(restore ROM)-->??

Yes, you can flash the Agat kernel from EL26 and then restore the CWM to restore the backup.
The Agat is a safe kernel and fine for backup & restore and flashing mods but many phones have issues with flashing entire roms with it (no need to flash a different kernel unless you are reflashing the rom) so we recommend using the older EL26 CWM or EL29 Directboot kernels just for when you're flashing JB roms. The only time you would need EL26 or EL29 is for flashing a fresh JB rom. This why you see instructions for flashing the Project X rom using EL26 or EL29 Directboot and the same applies to any custom JB rom.
Note: Of course, always follow the special flashing instructions that are provided for any custom rom.

So the basic procedure in this case would be (from Agat Kernel CFW) --> flash EL26 cwm --> Flash CFW kernel --> restore CFW
Am I understanding you correctly?

Not sure why the extra step there.
You created the backup with Agat, you have to use it to restore it too.
If that's what you said, then yeah go for it.

My only concern was with the the fact that the rom is indeed JB based. Thanks for the help

nandroid restore kernel?

Took the plunge and flashed custom ROM and kernel. Battery is being sucked dry at a rate about 10x faster than my stock config. If I restore my nandroid backup from before flashing anything, will the Kernel be restored too?
On the Epic4G three kernel was ina separate partition that had to be flashed on its own. Nor sure if the new memory architecture works the same way.

yes, nandroid restore from CWM will restore your kernel too... and you always have a fastboot option to flash your boot.img again if you want run a custom rom with stock kernel
Ahhh... thanks! Wasn't sure if the boot.img listed in the status messages from CWM was the kernel, or something else (like the bootloader, the recovery image, or something else). I'll submit a request to koosh to maybe add parenthetically to the status messages something like this:
backing up boot.img (kernel)
restoring boot.img (kernel)

[Q] ICS nandroids and cwm

Hey all,
Is there anyway to get a version of cwm that can:
A) backup and restore nandroids on ics safely, ie, backup cm9, and restore a backup of fc15.
B) safely do all of this without bricking.
If not, do you guys think this ice, cwm, and bricking will ever be fixed? Thanks in advance!.
P.s., tired of having to Odin back to el29 to flash new roms from ics...........
Thanks!

I use mobile Odin for replacing stock kernels with repacks then use ROM manager to boot into cwm recovery and flash away. Never wipe data in cwm or use reset as partitions changed. Calks format all

[Q] Alternative reliable nandroid?

Ok so after the AOKP hard brick debacle, what is the preferred method of Nandroid backup (if any) for ics roms or even just gingerbread roms. I am not messing with rom manager to backup my roms anymore. Someone said rom manager is taboo on this forum lol
Odin/Mobile odin the el26 cwm kernel and backup your setup there. Once done, you can either just reflash the rom or flash a compatible kernel so it will boot.
If you ever want to restore, just odin/mobile the el26 cwm kernel, restore nandroid, then flash compatible kernel so it will boot.
So i can use this method to backup an ics rom? I would be using mobile odin pro. The EL26 kernel.
Yes. And you would also need the kernel for the rom. After you backup or restore you will still have the el26 kernel. So you would need to flash the kernel actually meant for your rom

[Q] Can you Nandroid ICS using AGAT's?

I was wondering if I can Nandroid my current ICS setup using AGAT's? Whenever i backup using the EL26 Kernel, I have to go back to 1.85 odin, and Flash an ICS Kernel. This also adds the yellow triangle (ugh). I use mobile odin to flash my ICS Kernels. But when i restore using th EL26 Method, It requires me PC odin'ing a ICS Kernel. I learned my lesson hard bricking messing around a few days ago. I seemed to have no Problems Flashing multiple ICS roms with AGAT's recovery using the regular method (which was not how i bricked), And i even restored flawlessly a backed up setup without having to use Odin to flash a ICS tar since it can't boot without one. Anyone have a more convenient way? Or can i just use AGAT's to backup and restore my ICS roms?
Yes, the AGAT Recovery supports nandroid backup and restore.
Done it a few times going back to his earlier repacks. With the additional safety he has built in with the help of Chirs41g and sfhub I think they are very safe.
I actually create a nandroid close to every day to copy to my PC. Keep trying a few other ROMs; wiping flashing checking them out etc., but come back to Agat's work (via nandoids) because, for me anyways, everything works. And works very well.

[Q] Restoring From A Different Recovery

Hi all. I'm coming from a HTC Evo so some things on the touch are a little different to me. My question is this: I have noticed that some roms require a specific recovery be used. I am running AGAT recovery now but the rom I am wanting to install requires CWM. If I flash this rom and recovery, how do I get my AGAT backups if needed. Do I just reflash AGAT and use them? Like I said coming from an EVO, I only had one recovery (AMON) for all my needs. Switching back and forth between recoveries and how to do it is new to me.
Thanks,
LJ
CWM backups done in CWM or CWM based recovery should work in any CWM recovery of compatible version. TWRP, being a different case.
This phones recovery is packed in the kernel which you might have found out by now. You can flash kernels in recovery if they have a zip or you can use mobile odin (desktop odin as well) to flash tar's.
You can flash the kernel you used for the backup and then restore the backup if you want. If AGAT's recovery is CWM based (many are) you can flash most roms with it. Thats the entire point of it. But once you flash the rom you will have whatever kernel/recovery that rom has until you flash another one so it will change on you. If your going AOSP (cm9 etc) then stock cwm is of course recommended.
Thanks for the info.

Recovery restore
How about if I backup using 4EXT and would like to restore using CWM ?? will it be still supported?

There is not 4ext recovery for the epic touch. And no cwm wont restore backups from any other recovery except cwm or a cwm variant
