Is there a way to flash between ICS roms faster?

I usually one click back to el29, install CWM, and then flash another ICS rom but it's very time consuming. Is there a faster and safe way?

What I did was nandroid my gingerbread system. Then I can flash whatever I want and restore gingerbread whenever I want to go back.

Restoring a GB nandroid on an ICS ROM won't cause the phone to brick?
Sent from my SPH-D710 using Tapatalk 2

It can. I'd suggest just keeping chris41gs ICS aosp/tw kernels in SD card. That way you can just Odin his kernel (if you're not already using it) and flash whatever from there

I have done it dozens of times using Chris41g and agat's ics kernels.

so i got a question that ties into that statement. i am about to use the auto root tool to get cwm. i am currently on stock ics rooted. would i be able to flash whatever rom i choose without having to one click back to a GB Build?
(this used to be way easier on my OG Evo, lol)

Yes you would. Just install FF18-CWM-agat-src kernel. Of course make a backup first just in case you get into trouble but I have been doing it over and over with no issues... So far :laugh:

Awesome thats just what i Wanted to hear

Restoring back to nandroid.

I'm on cyanogenmod 10 beta 3 and wanted to go back to AOKP Milestone 6 but I'm having problems with superuser (and therefore cant use mobile odin) so I was wondering if I could just restore my nandroid back to EL26 via the JB recovery mode and then flash the aokp ROM through that recovery like normal? Or would that not work/brick my phone?

Bump, really need some input on this. Any help is appreciated. thanks.

Safe bet as I had the same issue: use sfhub one click to go back to el29 w root, then one click root to el26 cwm access and then you're good to go. Just make sure whatever road u take it leads you to el26 cwm by chris41g.

I don't really have a PC at my disposal at the moment though is my biggest problem :/ which is why I was asking if restoring back to my nandroid back up via JB recovery would be safe?

Hey, quick question.I'm just trying to do some reading about safety and such, and came across your post. Wouldn't it be safe to JUST Odin EL26 CWM alone? Without going back to EL29 first? Is that necessary? Again, not being a smartass and trying to call you out, I'm just really trying to get a hold on what is safe, or not, and procedures.

Well the main issue is it seems he lost root access....just saying its safest to start fresh. Only takes 10 extra minutes. If he had root he would've been able to just mobile Odin el26 like he stated, but its not an option.

Exactly. That's the problem I'm having, which is why I'm asking if (since i dont have a pc to use) It would be smart and safe to just restore my nandroid (which is el26 with root and cwm) from the JB recovery (cwm6) and then just flash my original ROM through el26 cwm.
Anyone think this is safe?

It sounds safe, both are quoted as being safe recoveries. I even restored a nand from a broken phone onto my replacement one yesterday so I'm sure what you're doing is far less risky. Its the wiping in non-safe recoveries that caused bricks, you should be OK as long as you don't do something stupid like pull the battery during the restore.

Someone else told me that even while restoring a nandroid backup, it still wipes data, so if you're on an unsafe kernel, it still can brick. Just so everyone knows, I was on a safe kernel when I bricked mine. Apparently there was a mis-merge that happened that caused the safe kernel to be unsafe for a few days. I was very unlucky, but its one of the risks we all take when doing this. I'm planning on odin-ing el26 kernel whenever I need recovery from here on out!

Thank you both for the replies. I guess I'll go ahead and try the nandroid restore.
Wish me luck haha. Hopefully this recovery is as stable as people have been saying lately.

Just thought of something: if you lost root, how do you still have a custom recovery? You may want to wait til ur near a PC to do el26 flash!

No idea but I can boot into CWM just fine, its just superuser won't give me root access. I even tried to do the su binary update and nothing.
I'm not flashing El26, I'm just restoring to my nandroid backup which is el26.

Bml/mtd?

Excuse my stupidity, but I'm just curious.
I'm about to get an et4g and id like to know if it has the filesystem type Change like on the original epic; where the official Odin Rom is bml and cm9/aokp is mtd, and how once you're on mtd you can't go back to bmp without Odin

No because the kernels are different. AOSP kernel and TW kernel.

For that I would read how to not brick your phone here: http://forum.xda-developers.com/showthread.php?t=1525495
and make sure that your in a safe recovery. Agats recovery is safe for ICS restore and flashing. so to restore a back up flash the kernel in odin/mobile odin boot into Recovery then restore back up.

Our phone uses ext4 file system. Don't have to worry about bml vs mtd like the og epic. No worries though I was wondering the same thing when I made the switch a few months back
Just make sure you read up on the emmc bug before you flash any roms as that can cause hard bricks.

If you are on Stock GB then your fine its a safe recovery. Flash GB to GB or GB to ICS. ICS to ICS or ICS to GB is another matter Agat's kernel(TW) and Chris41g kernel(AOSP) are safe for ICS. ICS to GB i'd use EL26 Direct boot kernel to GB recovery and restore or flash GB rom's from. Odin or Mobile odin work.

Going from ics to gb

So basically I was having issues with my phone and ended up getting a warranty replacement. So b4 I sent my old one back I needed to revert it back to stock. I found a flashable zip from zedomax that returned the stock kernel, recovery, and ROM. Only thing it was 2.3.5 gingerbread. I was running infamous 3.1 and did darkside super wipe and cache., well after flashing the zip I got the stock recovery, and part of stock boot animation, well after the stock boot animation then came the infamous animation then nothing. It wouldn't boot up past that.,I ended up using Odin and fixing it and converted stock that way. My question is... Is there a special method going from ics to gb?

Yeah just use odin or a flashable zip to return to stock no big deal

I know how to Odin and get stock...I'm asking if there's anything special to go from an ics ROM to a GB ROM? BC when I did it I soft bricked, using all the darkside
Wipes.

don't use the CWM flashable zips. if you do you should flash the rom and kernel too? you probably did but sometimes it doesn't work correctly. I would suggest flashing via odin to get to stock then wipe data/factory reset through stock recovery. that is the cleanest method to get to stock. the CWM flashing to zip sometimes leave stuff behind from earlier flashes.

Odin back to the recovery you made the nandroid in. If it was el26 and you are now on a agat odin back to el26 boot imto revovery. And restore backup or whatever recovery it was created in

I deleted it because it was a stupid question that I should have known the answer to. It was when you recover a nandroid does the recovery and kernel from when you made the android come with it.
My problem was I am and was on king kang and decided to flash a modem. I didn't realize the jb modems were only for tw roms so when I had no data I though I needed to update prl and profile. I flashed a stock rooted rom from repository, it was rooted but didn't mention had no recovery. Odin kept falling when trying to put a new recovery on. And after 5 hours of fail I finally succeed with a one click from repository. After flashing a modem (fi27) I think. I just wanted to make sure I want going to be stuck with no recovery again because that really sucked. I didn't mention this in the original question but all is well now and I'm back on king kang
