Can you go from CM10(.1) to TW ROM? - Epic 4G Q&A, Help & Troubleshooting

I want to go back to TW, not stock though.
My laptop is broken so I can't Odin or flash anything. So I was wondering is it even possible to go back to TW by flashing or am I stuck with CM10?

YES WE CAN! Any MTD TW ROM will do.

I would go back to TPR but I'm scared. They say you should Odin to stock then flash TW but I can't Odin. I can flash though!
Are you sure?

I think they say odin to stock because (if I remember correctly) the /system /data and /cache partitions are different sizes on CM than the TW MTD ROMs. I would PM kennyglass and ask him if the partition sizes on TPR and CM are the same.

Cm10 actually has a larger system and smaller data partition. So if you are wiping data and installing clean TPR will work in that partition. If you are restoring a nandroid of TPR full of apps it probably will error out. YMMV. Worse case is either you could restore your CM10 nandroid or Odin stock and install TPR.

I wiped cache and factory reset and flashed TPR. It worked

Your choices are only CM7, MIUI, or the new stock MTD ROM. You have to repartition using Odin to go back to other ROMs besides those.

If you want to run an ei22 based rom that is not available on mtd yet, dl the ei22 mtd build and delete /system folder on there. Then add /system folder of the ei22 based rom of your choosing and bam! Mtd
Edit: I am 90% sure this will work. If it does, let me know and I will post in general.

You are probably on EXT4 now and trying to restore an RFS kernel. You can either flash a kernel like Samurai or Shadowkernel or run ext4toRFS.zip to return to that system. Other option is to Odin to EC05, root and then restore.

Going from CM9 to EL30

Can I go back to my back up of EL30 from CM9? The reason I ask is because CM9 is mtd and my rooted EL30 is bml. I have a back up using CWM5.

Nope... the only way to get back to bml is to odin back to it with the victory pit and repartition checked... somebody didn't study up on the subject before jumping in!!.

Lol. Thanks.. I didn't jump in yet. I was reading but must have missed the odin thing. I have not odin since froyo. I was hoping can just do a restore.

Just flash an MTD EL30 ROM and advanced restore data from your nand backup.

The EL30 ROMs have the hotspot too. If you are going to convert your backup here is the thread:

Is it worth it in your opinion. I will do research on the benifits but if someone wants to tell me the differences

Yeah, if you follow the procedure you will have your BML ROM converted to MTD, back it up as soon as you successfully boot to MTD, then you can try CM9 and restore your MTD converted ROM when you are ready.

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

It does help, a lot infact.
So this means I can back up my stock rom, flash cm9, then go back and restore the stock rom, it'll boot?

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.

I have flashed from GB to ICS back and forth a few times never really had an issue like that the only real issue I have ever had was a few apps force closing but a quick wipe of the cache took care of that issue

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.
