I want to unlock my bootloader but do but do not want to lose all data, so what adb script to pull out/system data and application data?
Thanks!
Hey guys,
I have Samsung S7 and I use iShredder v5 to erase all data but DiskDigger recover all data. So, I want a good Data Shredder which can erase all FREE SPACE and cant be recoverable.
Regards.
So my understanding is that in order to be able to make a complete backup of all my data which can't be backed up normally such as my browser data, game progress, protected apps etc I need root which requires unlocking the bootloader which wipes all the data I am trying to save. So how to I backup this data?
It's been many years since I rooted a phone but I don't remember the rooting process normally erasing all my data.
You can use HTC Sync Manager and Google Cloud services to save/restore apps and apps data. You have 3 hours or so to restore data from Google services cloud.
Hi all,
I know phone SD cards are generally very hard to recover once wiped, all the same, I wanted to make sure.
Wiped Data through custom recovery
Wiped Caches
Installed stock OS
Restored stock recovery
Wiped
Are these enough steps to sure the phone is secure and no data can be recovered? Thanks.
If you want to fully wipe phone before sale security, try phone data eraser tool. Such tool can help us wipe all information on phone without recovery and make it like a new one. Then there is no need to worry about data leaked. Just search it online and choose the one you like. Good luck to you.
The same zero out technique I use for hdds, with a 5 pound sledge; flatten completely and then some.
Sometimes a oxyacetylene cutting torch... a nice bonfire gets it too.
Zero chance of data recovery and fun to do

As @blackhawk mentioned: Overwriting Android's user-space several times with zeroes is fully enough. You even can do this by means of ADB.
I always just plug up to my laptop and do a: sudo fastboot -w
I've sold quite a few devices of mine over the years since Android began and t.ive always just did a format data using fastboot.
If you had some super top secret information on there maybe use some type of cleaner software program like another user here already mentioned. I've never used anything like that but I've read about them over the years online. I think a ./flash-all.sh and and not removing the fastboot -w flag is enough though, but that's just me. There are things you can purchase that will supposedly wipe it to where three is no possible way of anything ever being retrieved.
One of the most thorough ways to wipe the Android device is the factory reset.
The f actory reset deletes the complete relevant data - both the system settings data and the user settings and user data. The system applications are reset to the delivery state.
The factory reset deletes all subfolders of data (only lost+found remains) and deletes cache/dalvik-cache.
Hello Everyone.
So I have an unused phone that i wanted to sell, so I Factory reset it.
But then i look at some article and found out that Factory Reset doesn't completely wipe the Data, and it could be recovered by 3rd party program.
So the question is, if I Flash my phone to a stock firmware, would all the previous data be completely erased?
I just want to make sure that my data is completely lost before selling it, since it contain lots of sensitive information.
My Phone is Sony Xperia X Performance.
Thanks in advance.
A Factory Reset wipes ALL user-data and restores system apps to the state when phone was delivered.
BTW:
Wiping and Erasing data although can sound similar refer to different things data security business.
In short, Erase command erases or overwrites all of the data on the targeted drive, while Wipe command marks disk space as deleted / re-useable that is not being used by the Android OS ( unallocated space ). Wiped data theoreticaly can get recovered.
My recommendation: Do a Full Wipe
Code:
fastboot devices
fastboot erase userdata
