Hello,
I am planning to do a twrp backup before i install a custom rom on my international (india) samsung galaxy s6 edge.
But as it does not have any external memory, the backup would be stored on the internal memory, so when i do factory data reset, wipe cache and wipe dalvik cache, wont the backup be lost ? And is there any way to access the s6 edge internal memory on a pc if the phone does not turn on ?
No. A factory reset wipes cache, dalvik cache and data. It does not wipe internal storage. If you wipe internal storage through the wipe options in TWRP, then you'll lose your TWRP backup. You can always copy your TWRP backup to a OTG USB device or a laptop and side load it later on.
A PC can detect the S6 in download mode. From there you can reload the stock firmware via Odin or Samsung Smart Switch. However you wouldn't have access to the contents of the internal storage.

I have got a samsung GS3 which i would like to flash a custom ROM on.
The phone is rooted and i have done
Get into the CWM recovery
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Install the wipe version of this ROM
The problem is that even after all of that formating and deletings there are still some old files on the phone like airdroid, total recall,....
Can someone explain please how to get rid of that?
Is there a way to flash a ROM from the external card and if not where do i need to put it in internal storage?
TIA
You won't get rid of all files on the internal memory. The wipe process does wipe the memory clean but the phne uses the internal for its own storage and sets it up respectively.
You may have a few extra files added if you flash a stock rom as it too may add a few system files....
To check, go to system>storage. You should have around 12Gb of storage if you own a 16Gb phone or about 28/29Gb if its a 32Gb phone...
thanks for that. Maybe got an idea how to flash from external sd card or where to put the zip file on internal memory?
You can flash Roms using Mobile Odin which claims to be S3 compatible but I never tried, and anyway i'd stick to flashing from Pc because it's a lot more reliable.
Hi All,
I did a factory reset today and flashed the stock 4.1.1 Polish ROM via Odin. This process seems to have wiped my files (including photos etc) from my S3 (internal memory, not SD card). I've flashed plenty of ROMS before and this has never happened.
Anyone know if it's possible to get them back? I guess I've installed new apps etc now so a lot of the data would have been overwritten. Frustrating!
Thanks for any tips.

You answered your own question with your first sentence : I did a factory reset...
Unfortunately its not possible to get back the data

Unless you backed up on PC or sd card...
Factory reset in S3 will always wipe internal memory as it shares internal memory for applications.
If you want to restore try some data recovery software that supports SD card.

That would be the only way. There is a very small window to recover data wiped from flash memory and on a phone it would be even more difficult. Maybe a Clockwork backup?
Internal SDcard is mounted on the system partition via Fuse..so if you format the /system partition..sdcard is formatted as well..
Pointers for future..
Use CWM for flashing ROMS..(I hate Odin )
Backup your internal SDcard on your PC regularly
Perform a Nandroid Backup on your ExtSDcard before flashing any ROM.
If you ever need to factory reset..use the wipe data/factory reset option in CWM and not in Stock Recovery
For a clean install, if you want to wipe system partition..use wipe /system option under mount and format in CWM..it just wipes the system files and your SDcard data will be safe..
You will not face such issues if you in the future if you follow these pointers.

Thanks for that. Lesson learnt I guess..
So,first time when I installed a custom rom on my s3,I used CWM 6.0.4.6,I think,I wiped data/cache/dalvik and when I boot up the phone,surprize my interal storage was wiped,so my question is:Is it normal if wipe data to wipe internal storage(on s2 wasn't hapening)?On TWRP is not happening.
Check in /data/media to see if your legacy data is still there. Internal storage is wiped if you factory reset from within rom or you format /data/media.

Hi all,
I've been using CWM to routinely backup my S3 thinking that if anything happened I could just to a restore to recover everything.
So, the other day I did a backup using CWM, then a factory reset via phone menus. Updated the firmware via Kies and restored my apps and data via Titanium Backup. However I'm missing a heap of photos that I believe were on the internal SD Card.
OK, so I do a CWM backup and restore my previous backup before I updated the firmware thinking it would recover my photos. But they are not there...
My questions:-
1. What deleted my photos?
2. What should I have done that I obviously did not do?
3. Does CWM or TB backup the internal SD Card Data?
4. Does CWM backup differently if it is to the External SD Card? ie: Include the internal SD Card data.
Any help would be appreciated.
TIA
Greg
1. You did, by factory reset using settings menu this wipes internal storage.
2. Used recovery to wipe. Factory reset in recovery doesn't wipe storage, only data.
3. Only if you set a custom backup and have space for 16gb on your external storage.
4. Not unless you change the default settings.

Many thanks for all the useful information.

My father had a softbrick of his Galaxy S2 without having done a backup in the last 6 month.
Now he need some data that are stored on the phone so I cannot do a wipe data factory reset and I was wondering if I install a custom recovery can I move all the datas on the Sdcard and then read them from a microsd card reader?
Will installing a new recovery change the data?
Thanks
EDIT:
I solved the problem.
First I installed the Philz CWM recovery, that I reboot the phone in recovery Mode and chosed to mount as USB drive so I could copy the content of Sdcard.
Then I did a backup of data and system Partition through the backup menu on an external Sd card, after that I did a wipe/factory reset and the Phone reboot regularly
To recover the information that you need from the Backup can you use TitaniumBackup
I'm quite sure that the /data partition will stay untouched, since the recovery image is installed in another partition.
BTW, on some recoveries I was able to connect the phone to the computer and to read internal storage. Are you sure it's the data partition you need? The only thing stored in this partition are apps and app data. Images etc are on the internal storage (sdcard0).
Hope this helps.
I thought that Data and Sdcard were the same partition, what I need is to recover contacts and Viber/whatsapp message and images.
If I install a Custom recovery can I do a backup of everything and could I use adb to do a complete copy of the sdcard?
Thanks
