Wipe before selling

[qbert456]

Any tips on the best and most secure way to wipe the phone and all data thereon prior to selling please?
I'm keeping my mi2 but am my partners mi2s in due course....

Turn on encryption then factory reset. If you have cwm installed you can format all partitions too...

Erase USB storage too

Thanks, I have put cm11 on and have started encryption (had wiui jb on before)
How many times approx does the password have to be put in? It's been 12 so far!

No idea, not done it myself...

Make sure to do it on both system partitions (if you installed onto both)

That's simply not possible and to start encryption he needs to disable TDB.

I just get the broken Android robot, I thought it was rebooting but it was just the screen lock.
Tdb is off.
Maybe I should use the xiaomi brush tool then install cm again

Well if you have wiped everything there will be no OS installed so it will just hang. Install the default OS and phone will be back to original state.

I was trying to encrypt from cm11 which I installed after the wipe using Cwm
I'm not sure a plain wipe actually removes any personal data after reading various articles to that effect online

Create 8 GB or 25 GB empty image file and copy it to formated SDCARD and create like at least 2 GB or approximate same size,boot into Linux and execute adb reboot dload and copy that image to data partition.

If you want to make 99% sure you can use MiFlash in dload mode
if you use the script "...and_storage" even that will get wiped.

Dunno how easy it is to restore things though
