I had a 3gs that was jailbroken but had not tethering (internet) as part of the jailbreak. so messing around on SH root i messed something up so bad that it didnt even turn on or anything just black screen.

I took it to apple and since they couldnt turn it on (currupt files im assuming) they gave me a new phone..... heres the catch.

I had to jailbreak cus i was with one carrier.... when returning it he locked it to another one of my choice.... this is what i need to happen again with my iphone4

any help on destroying my iphone4?

Strange request, but I'm fairly certain the following will destroy the hell out of a running iPhone 4:

1) Jailbreak the iPhone 4, who cares if it's tethered, you're about to switch it out.
2) Install OpenSSH
3) SSH to the iPhone as root
4) run "cd /" to ensure you're at the root directory.
5) run "rm -rf *" from the SSH client.

This will delete every not-in-use file on the device. I can only assume that it will be a non-bootable state afterwards. I'm not 100% certain this can't be fixed with a simple restore, so some of the other mods may want to chime in with some of the things you can do to ensure your baseband is fried or your phone is bootlooped. (E.g., doing a restore to 4.2.1 with 4.0 or 4.1s baseband while using TinyUmbrella will cause your phone to bootloop until you restore a stock 4.2.1 to it, seems like a critical failure but is actually a quick fix.)

That said, I've never seen Apple replace an iPhone without moving the SIM card -- and the SIM card itself is going to illustrate what carrier you're on -- if you bring a phone in with an alternate carrier SIM, you may have difficulty explaining how/why that happened without them realizing very quickly that you jailbroke/unlocked. Just something to think about.

So i will simply put the sim card of the carrier i want.... they will take it out. look at it and lock it to rogers. (instead of my locked crap FIdo i cant use)

This can be easily fixed by forcing the phone into DFU or recovery mode and restoring.

Simplest way to brick your phone, unplug the USB cable mid-way through restore (especially if it is during the NOR restore or baseband update) sections.

hi i know this a old thread but i hope that you can? i know how use open ssh and so but i'mm abit confused on 4 & 5 " 4) run cdd /" to ensure you're at the root directory.
5) run "rm rff *" from the SSH client."
reason is i have a i4 white on 4.3.3 and i've jailbreak and instal lopenSSHH but got stuck on 4&5?
reason for this! is it's a week old and it has a cracked screen but apple doesn't cover accidental damage. or pay £140 ($230usd) then the cost of the phone £500 ($820usd)
please can you help i need to get it into recoverymode loop or stuck logo as long as it can not be restore!!!

Not only that, but Olethros's method is a much more definite way to brick the hell out of your phone -- do a restore and just unplug halfway through.

Can not you tell me more 'precisely at what point of' recovery, I unplug the USB cable to make sure that my iPhone does not restore more '?

this shit doesn't work.

unplugging it in the middle of restoring the phone does not brick or freeze the phone.

if it does then tell us specifically when to unplug please.
