3G Total Wipe

[sandman2]

3G/16GB 3.1.2/05.11.07 running 3.1.3 faker, JB and unlocked with Tmobile and clicked on make my life easier at Cydia.

I would like to wipe this phone and start from scratch with 3.1.2or 3.1.3. Bought this thing on fleebay and it has a huge battery drain problem...phone works great and yes the battery has been replaced.

What would be the easiest procure to accomplish this?

Thanks in advance.

Put your iphone into recovery mode and then shift + restore to 3.1.3 .
Jailbreak again with redsn0w 0.9.4 but point to 3.1.2 ipsw

[sandman2]

I have 3.1.3 downloaded...do also need 3.1.2 downloaded? Oh, running XP OS on PC.

[iYeow]

Yes, you will need 3.1.2 as well when you run redsn0w.

[sandman2]

1.Is there a step by step guide around here somewhere for this procedure (thought I saw one in the past)?

2. What about the unlock?

3. Thanks for the amazing response time.

[iYeow]

Yes, right here :

You can install ultrasn0w from Cydia to unlock.

You can download your firmware from here : http://iclarified.com/entry/index.php?enid=750

Should there be a link for the How To Guide?
Thanks Again for your help!

Yeow202 told me to put phone into recovery mode, but tutorial recommends DFU mode?

Are they the same?

They arent the same, but are similar. DFU you will see nothing on the screen, restore mode you will see the usb cable and itunes icon. If you are using redsnow to jailbreak you will need to put it in dfu like the guide says.

Is there a guide more suited to my situation around here anywhere?

Just put your iphone into recovery mode and then do the shift + restore to 3.1.3 ipsw.
Recovery mode : Turn off your iphone , while holding the Home button, plug your iphone in until you see Itunes cable logo.
Then Itunes will pop up telling you are in recovery mode and need a restore, you click OK

X98car posted DFU mode...confused (might not be cut out for this stuff).

OK, at Shift + restore do I select 3.1.3 ipsw that I downloaded?

[iYeow]

When you are downgrading, you put your iphone into DFU mode.
When you are restoring to the same firmware or you are upgrading you put your iphone into recovery mode.
Only cases like, if you are using Geohot's exploit, then it is a special DFU mode you have to put for the exploit to work.
In this case you are not using his exploit.
You can use dfu mode, either it will work or it doesn't and will not hurt your iphone.

JB and unlocked...wasnt to bad after the fear factor. Had to do it twice because I did not remove SIM I think. Thanks again for all your help (yeow202).

[iYeow]

Glad, it all works out.

[sandman2]

Yep, thanks again. I might try your custom 4.1 on a 3g 8gb junker I have laying around here.

Is the procedure the same?

Restore to custom firmware created by Snowbreeze 2.1 or Pwnage tools 4.1.2. If you run into errors, run Ireb 4.1 RC2 first and then restore to the custom fw 4.1
