[Q] Change csc without data wipe - Samsung Galaxy S7 Edge Questions and Answers

So, my location is ZTO but I've flashed BTU when I debranded my S7E. Turns out, Samsung Pay just launched here (but my phone doesn't support it... My guess would be the CSC).
But, as far as I know, changing CSC results in factory reset. Is there any way to flash ZTO without wiping all my data?

You could try the csc zip in the roms kernel etc thread. That doesn't wipe data.

probably better to do a full wipe before any flashing however. or backup data, wipe/flash away, restore data.

Would reflashing the stock firmware via odin wipe data?

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 )

Fix freeze , lags etc.

Hello people my phone getting old i think 1.5 year so far my phone started to freeze having lags getting too hot while browsing. And bootloops started without flashing anything. First bootloop happened 2 weeks ago. Today happened again twice i wiped dalvik cache and everything is fine how can i fix it? I thought rom cause it i flashed stock firmware rooted it and removed bloatware. Still happens lags,freeze,getting too hot and bootloop. Is it lollipop update? I never had this issues with kitkat. How can fix this and keep my alive?

Try a full factory reset. Be careful as this will wipe your internal storage.

Thank you for your answer but I did it after flash stock rom via odin. Wiped data / factory reset , cache partition , mounted cache , system , data , wiped dalvik cache..
Wiping data does not equal a factory reset. Wiping data does just that, wipes user installed apps. But generally leaves the internal storage alone.
A factory reset returns the phone to the settings it came out of the factory with, including a clean internal storage(If you have the stock rom). I heard that changing roms and just wiping data, dalvik and cache will still leave behind some files.
But it could also be untrue.

Flashing stock rom is same with factory reset i think clears everything.
I don't know. Haven't flashed stock on this device yet.
But don't most guys recommend doing a wipe before going back to stock?
I dont know i'll try that when i have free time. I did research some guys saying lollipop causing these problems. I'll try wipe before flash stock rom again , if issues keep happen i'll use lates 4.4.2 custom rom. Thank you for your answers i'll report back.
Real reset
This method will wipe everything, including operating system and efs files. Before you do this:
you must root
Download twrp recovery
Install the recovery using the app from the play store
Boot into recovery mode and have twrp backup everything
save your backup to an SD card and the computer (can't hurt to have two backups)
Doing the above will preserve your phone important data like your imei and efs
in case something goes wrong.
NOW
after you have backed everything up use twrp recovery to wipe data. Have twrp wipe everything except for your SD card (don't won't to lose the backup)
After everything has been obliterated have twrp boot you into download mode.
Download Odin from XDA preferably 3.09 (most stable release) and then grab an official stock firmware from a trusted source. The latest stock firmware should be at least 4.4.2
If you have carriers other than t-mobile you will also need to find a PIT file for partitioning.
When you have all of this open up Odin with your phone connected in download mode and make sure repartitioning, clear efs and nand-erase is checked along with the defaults.
Select pda button and choose your firmware (unzipped tar.md5 format.) Then select repartitioning PIT file button and direct to where you have the PIT file downloaded.
now click start (be sure that the Com port is recognized by Odin: will be highlighted in blue or yellow.)
This will take a while depending on your computer.
when it finishes your phone should reboot with a fresh os and filesystem. If you get stuck in a bootloop reboot into recovery mode and do a wipe data and wipe cache. Reboot and your phone should be good as new.
IMPORTANT!!! It is vital you keep your TWRP backups for as long as you have your phone if you lose them and something goes wrong while flashing your phone you will lose important things such as IMEI baseband which will prevent you from connecting to your network and Sim card recognition.
Thank you so much i'll try this now.

Is that another custom recovery?
If so then yes just make sure you have all of your system files and most importantly your efs backed up.
Run odin as administrator if that doesnt work, try using another version of Odin.

Doesnt work another versions both twrp and odin. I'll keep my custom recovery and try it.

What carrier are you using, model number of the phone, etc.
Have you backed everything up? And can you flash the custom recovery through Odin if it fails?
Try it without wiping efs first just to be safe
Look here for your device you will be able to find standalone flash able versions of twrp that should work through odin.

Using i9500. And i did what you said and works fine thank you! Mods close thread please.

Wipe and Flash

Hi. I have installed Doctor's S6 Port ROM in my i9500. I'm having some signal issues so I want to go back to stock rom and try signal. Here's the question. Can I full wipe my device with custom recovery (wipe data, dalvik, cache, system, preload) and then flash stock firmware with Odin?
Another Question. The Stock rom file I have is HOA7 and my current bootloader version is I9500XXUHOA7 and the modem is I9500ZCUJOH2 (this modem came with doctor's ROM). I want to download stock rom HOH4. This stock firmware will upgrade bootloader and flash a new modem? Also, what happens if i have a higher bootloader than firmware. Example, if i have HOE3 bootloader and install HOA7 firmware?

Yes that would be the correct procedure. Wiping with the custom recovery and then flashing rom with Odin.
The bootloaders are not that strict. You can switch freely between Lollipop versions.
If you are having signal issues why not just swap between custom roms? Maybe try a few different Lollipop modems.
Make sure you do the advanced wipe in TWRP.
Doing a factory reset will only wipe /data, /cache and /dalvik.
Select andvaced wipe and select the partitions manually.

[Q] Flash to stock with full reset

Sorry to start a thread for something that I think is simple. I want to update my S5 to the newest PF4. I was on a rooted 5.0.1 before. I didn't care about keeping root, etc.
I used SamFirm to download the newest firmware. Then ODIN to flash the newest firmware.
The result was it upgraded my phone to 6.0.1 instead of a clean install. In the old days, I recall having to clean cache, clean Dalvik cache, and maybe some other steps.
I simply want to nuke my phone 100%, and load it with the stock firmware PF4.
If I reboot my phone into recovery I see Wipe Date/Factory Reset and Wipe cache partition. I envision that is what I need to do, but looking for confirmation. Also, does the order matter?

You just need to flash a full factory tar from odin
Where do I get a full factory tar? I used SamFirm, the screencap is below.

You can use Samsung smart switch emergency upgrade and initialization option to fully wipe and upgrade your device.
Or just flash the stock firmware, and then go to recovery and do a factory reset.
Sent from my Galaxy S 5 using XDA Labs

From 6.0.1 to 7

I'm still on 6.0.1 if I download and install Nougat via Odin will all my data, pics etc remain or get wiped?
if you use your home csc it should not wipe the data (if your region still dont have Nougat use Csc from latest MM ROM in sammobile), if you flash other csc then you phone is on now it will for sure wipe your data. On the safe side do a backup Also worth mentioning that Nougat is a big update and a clean flash wouldn't be so bad After OTA I was going to factory restart my device but now its running very good so decided not to do that Maybe wiping cash in stock recovery did the trick
