Selling your Android phone? Don't. It keeps your data. - Sprint Samsung Galaxy S 4 General

I found this article online regarding Android phones:

Does anyone have any input on this ? It says a factory data wipe DOSEN'T actually clear the entire phone ?

Older phones did not clear the internal storage. Newer phones wipe the internal storage completely with the Factory reset in Settings. However TWRP has a wipe data option that does not wipe everything, just the /data partition. If you have any pictures on your phone, run the factory reset from settings. If afterwards the pictures are still there then it does not remove all.
If you really want to wipe the phone just Odin in a full factory tar image.

How do you COMPLETELY wipe a Samsung Galaxy S GT-I9000?

I am looking for a definitive way to COMPLETELY wipe a Samsung Galaxy S GT-I9000. I mean the equivalent of doing a full factory restore on a PC. I've noticed that no matter how many times I flash or factory reset that there are still remnants that remain. Files like the license for Titanium Backup, or just miscellaneous files. Is there a way to completely wipe the SD card clean first, then do a fresh flash? I really would like to know that the SD card is completely clean since I've flashed 3-5 different versions of firmware and not one has been stable. I just want a real fresh slate.
Please advise.
Thanks.
setting>privacy>factory data reset. thats what i do...im assuming its a clean sweep.
If you have an sd card you have to reformat that as well.

This will not format internal SD. After "factory data reset" you'll need at least to format this one as well.
Sounds like the OP wants to return the phone
Ha, ha. Not even! This is the best phone I've owned to date when it's working properly. I am tired though of it crashing on me. I'll notice I'm not getting calls or email, then I check it and the phone has shut off. I'm also tired of flashing it every week, and spending days trying to get it back to the state I like it. (I wish there were better cloning apps that saved ALL of the settings including how you have the home screens set up, and all system preferences. It sucks having to reconfigure 10 email accounts, among other things.) I'm thinking if I can wipe it and start totally fresh it will help.
Glad to hear that, that's the spirit!
it just that recently we've been getting quite a few anti SGS fans in the mix, and many people are returning their phones.
Yeah, I have no intention of sending back my SGS. The good far outweighs the short list of negative items; those only being lack of flash and a poor battery life.
I just want a stable system! I'm going to keep searching for a fix.
out of the box i performed a full wipe by doing this *2767*3855# (this code applies to all samsung models i think). HTH.

thank you sir.
Is there a difference between these three ways of reseting?
odin
best way is odin
do the full odin re-partition with pit
then flash the 3 files.
but you will still need to go into recovery and format the internal sd as pictures will still be safe on the internal sd.
What if you mount the phone as a storage device and "rm -rf" the sd-card(s) ?
Windows users could use cygwin...

You may try rebooting your phone and while rebooting holding volume up, home, and power until you enter the factory menu mode. From there select "Format internal SD". That may be what you're looking for?

Same problem in wiping Galaxy Tab
Hello,
I am also completely unable to wipe it properly. downloaded apps (like amazon shopper) remain and function even after formatting internal SD storage, and wiping it like 10 times.
Very disappointing.
Any suggestions more than welcome.
Thanks.
as mentioned above.
boot into recovery > mounts and storage > format system / cache / data / datadata/ sd card.
also do a factory reset, then wipe the dalvik cache.
flash rom thru odin with all 3 files and PIT
that will leave phone completely EMPTY
i thought the factory reset in the CWM should be fine

I have done that with the phone and its really empty cause it wont even start haha so what do i do now? how can i install somethin on it?
Personally I copy everything from my internal sd card on my pc into a samsung folder with that days date.
Then I then delete everything off the internal sd card.
From there I boot into recovery & format sd card. Then I do a factory reset, clear cache, clear dalvik cache and thats it. Everything gone. Now at least if I discover there is something I need missing I have it ready on my pc.
This saved me when I flashed an ICS Rom & lost my IMEI number. There it was sitting on my pc ready to go.
If you have flashed with Odin using the 3 files & the pit file with re-partition checked I've found that I often end up with the phone not starting. Usually a 2nd flash with the 3 files without the PIT file and re-partition unchecked and my phone is then fine.

How to do a full wipe?

Hello,
actually I have CM10 on my SGS. But recently the SGS has a lot of crashes when I'm using it. I want to completely wipe the phone(not just Data Wipe...) and then install CM10 again. How can I do that?
Like factory format, including wipe all the settings, apps and also files from the sdcard? If so, then you can type this code *2767*3855# (it won't ask for confirmation).
I think factory wipe is the same as "data wipe" in CWM. That won't help because I do a data wipe before flashing a new rom.
Format everything in "mount and storage" in CWM
I think the same

Hard factory reset isn't working, doesn't actually clear my data fully

Hello, I've been trying the hard reset function on the Samsung Galaxy S i9000 but it simply doesn't work fully.
After pressing VOLUME UP + HOME button along with the POWER button, and going to the recovery menu, I select the 'factory reset' option and it says it was 'succesful', even though it was fairly quick, around 5 seconds maximum. I also did the 'wipe cache' option and the 'format internal SD card' option, once again, it says 'successful' each time, but once I turn it on and finish the setup (language, network etc.) and then I head over to settings, it still has my Google account linked and it even remembers my wireless routers password? It also has a few apps left in there.
Keep in mind, I removed my sim card and SD card before rebooting after the factory reset, I still haven't stuck those back in so I can make sure I get a full factory reset.
How can I do a HARD reset, which removes EVERYTHING. So it's kind of like taking out of the box for the first time ever?
Any help is appreciated, thanks.
Have you tried wiping / formatting the SD and USB Storage in Settings
In recovery make sure you do the 4 wipe process (data/factory , partition , dalvik and battery)
Before installing any new Rom

Hello, and thanks for replying.
I'm not trying to install a new ROM, I'm just trying to wipe the whole phone because the phone has been freezing alot.
I have wiped out the internal SD as mentioned above, but for some reason, after I hard reset the phone and turn it back on, in the set up part, my WI-FI password is already there, and so is my Google account/password? Along with a few apps (and the memory card was removed the whole time).. that can't be right?
Sometimes a Hard Reset doesnt resolve the issue thats why we do the full wipe process in Recovery
Along with Unmounting USB and SD and formatting them both in Settings
In settings just Forget Network on your Wireless connection
In Accounts just remove account for your Google Account with menu
What Rom / firmware are you using
can u gives us ur cwn version n hav wipe dalvik?
btw, no juz wiping, fixing permission also can help a lot.
if u say some app still there after formatting, try to disable sync or remove account using gsetting first. then try to factory reset again with wipe cache partition n dalvik cache, manually wipe datadata and data on mount & storage n try to reboot again, and may i ask u what firmware or custom rom r u using?
and sometimes, taking battery out n press power button for 1 minute n release it n put back battery n reboot help resolve many problem occur on i9000

[Q] Install New Rom Without Deleting Photos,Video & Music?

I AAlready Rooted My Phone HTC One but Wanted to know. If There is a possible Way to install a New Rom without Deleting My internal Pictures Videos & Music What are Some Options?

The best option I have found is to use the Superwipe Script. It does a full wipe and optimizes your system for a ROM flash. It does not touch your internal SD card.

Wipe
This section is dedicated to wiping all standard partitions on your Android device. By default, TWRP offers you to perform a full factory reset upon hitting Wipe, since it’s the most common form of wipe operation that most users need in recovery. This will wipe all your user data from the phone, including your installed apps, cache, and dalvik cache. This will not effect the internal or SD card storage area of your phone, meaning your documents, downloads, pictures, music, videos and other files will stay safe.
If you would rather want to wipe EVERYTHING including the aforementioned data, tap ‘Format Data’. This will wipe all your apps, backups, downloads, pictures, videos and media, and will also remove encryption on your internal storage, if you have applied it, essentially leaving nothing but the operating system itself on the device, in a complete factory state.
If you want to be more specific about the partitions you want to wipe, hit ‘Advanced Wipe’ instead. You can then select one or more common partitions to wipe specifically, leaving the rest untouched. The partitions available for wiping include system (where your operating system is stored), data, cache, Dalvik cache, and usb-otg in case of our Nexus 4, but may (or may not) include other partitions as well. Just remember – if you are unsure of whether to wipe a partition or not, NEVER touch it, especially if it’s the system partition. If you are following instructions provided somewhere, wipe only the partitions that the instructions clearly specify to wipe, and leave the rest untouched. Otherwise, you might be stuck with a device with no operating system installed, or lose all your data stored on the device.

Perform a factory reset from the recovery, including the usb storage. Or you can delete the usb storage manually from android with file explorer before factory reset
factory reset does not delete the data completely susceptible to recoverable .
