My basic question is can I repeatedly reflash the same ROM to my Epic without wiping data between flashes?
I flashed a ROM and then manually flashed a number of add-ons and optional installs from other ROMs. My phone is now in a state that I don't like. I thought I did a nandroid backup after the initial ROM flash, but I didn't. I'd like to just reflash the same ROM that I already have on my phone, hopefully just wiping cache + dalvik first. I'd rather not wipe data and go through all that again if I don't have to. Is this safe to do?
Yes its safe. Only reason they say to wipe is going from one rom to other rom u may get some probs.

Hey,
I had G3mod kernel on almost stock JPU. I wanted to try the Astrum Kernel so I flashed it. Although now my phone only seems to boot to recovery. Once it reboots it automatically goes to recovery. I tried wiping cache and dalvik. Also tried flashing the G3mod kernel again, doesn't work. Anything I could do without flashing the whole rom again? Please help.
did you try a factory reset?
Why dont you flash again?

Thank you for replies. To anybody having the same problem. If you want to preserve your phone data (messages, contacts, log calls etc.) you have to flash the firmware again (in my case it was default JPU) without the 'data.rfs' file in the tar package. It will let you boot up the phone without losing your data and you will be able to backup them.
So, I'm on Stock 4.3, with Xposed Framework and franco kernel. My question is, can I flash the factory image for 4.4 directly, or do I need to wipe data/cache? I know I'll lose Xposed since it's not supported for 4.4 yet, so if my first question is not possible, and I have to wipe, I might as well get a custom rom. A second question is, once Xposed is available for 4.4, can I return from custom rom to stock one just by flashing factory image, without wiping data? Thanks!
to flash the factory img, you have to flash it via fastboot. itll wipe out your partitions when you do flash it, so wiping anything is pointless.
So I'll lose all data anyway if I update? Well damn.
Im planning to reflash my phone back to stock as a few things are messed up, will be flashing via odin the base firmware is UEND6 and will reflash the same firmware so that I can still root w/o tripping knox, would reflashing via Odin clear user data?
i guess not

I guess just flashing the firmware won't wipe the data.
I flashed stock over a CM install and forgot to wipe data. My stuff was still there but the install was definitely a little bit unstable with background apps crashing. It didn't wipe data, but the phone needed a data wipe afterwards to be usable...

I kinda need to get my data back before wiping, I installed 3 new xposed modules and I am not 100% sure which of the 3 is causing the issue, Im stuck at the Samsung logo.
EDIT:
Im wondering if factory reset would delete camera photos stored on the internal memory, if not I have most of my impt stuff backed up online.

Install TWRP recovery (will trip knox) and make a TWRP backup of the entire phone including data partition. Once inside TWRP recovery you can also mount /data and adb pull whatever data you need from it, including the backup. Not sure what to do if you need to access embedded app data that you can not pull through adb.
When I flashed stock without wiping data my files were still there though.

My data is not that important to trip knox

In that case I would just flash stock and see what happens,

Still waiting for the download to complete. Samfirmware is only giving me 300kb/s and I dont know where else to get stock firmwares.
To close this issue with a resolved status, I would like to say one thing.
If you flash a leaked firmware - it will wipe your phone.
If you flash a stock firmware - it will NOT wipe your phone.
Factory reset will not wipe your internal SD.
Installing TWRP or anything unofficial will trip your KNOX. If your data is worth losing warranty - go for it
I was with a UEND6 firmware and just gonna flash the same to get my data back and factory reset the phone.
EDIT:
Got my data, everything seems to be perfectly working aside from the task manger, Gonna factory reset the phone and probably reflash with odin to have a clean start, would ticking repartition be necessary for a fresh install ? ( but I remember that required a PIT file )
The reason I ask this question is because I recently flashed stock ROM of 5.0 when I already had 5.0 installed to do a fresh and clean install. I noticed that after the flashing all my data was there like my phone was never flashed (I'm 100% sure I done it right).
If I were to be on 5.0 rooted, and then 5.5 comes out and I flash to 5.5, will I just lose my root or would I lose both root and all my data?
No you won't lose your data unless you reset after flashing, you will likely lose root though, definitely if using ODIN
I recommend clearing the data when flashing any new rom. You can get bugs otherwise. Why are you going from stock to stock? Down grading back to kitkat?
