[1.1.2OTB][HW Unlock] Guidelines to avoid bricks, virginizing and 1.1.3
After doing a couple of successful hardware unlocks with the help of this forum, I thought it was about time to give something back. I have payed attention to whatīs been going on with users performing hardware unlocks the wrong way and thought that I could help prevent people doing the same stupid mistakes. This is NOT a guide, simply a heads up on common errors that people do.
First of all, restore to a fresh version of 1.1.1. Install the latest Installer.app and follow the instructions on this guide as if your life was in danger:
Their servers are a bit slow at the moment, but I would imagine this is because people are following it.
Common "problem", or at least something that people cant comprehend to:
"Iīve lost WIFI, what do I do?"
The very first command that you write in terminal (if you follow he guide above, this is what you will be doing over wifi) on your computer is (simplified): Unload CommCenter. This command tells your OS to shut down the very heart of your wireless communication circuit on you iPhone. This means; NO WIFI, NO bluetooth and NO telephone functions. If infared was built in to the iphone, this most probably would not work either. The guide then tells you to write:
If you do this via SSH, nothing will happen. Why ? Because you have NO WIFI!! Turn to the iPhone, open Terminal on it and write the commands there.
If you are struggling with making the testpoints, your phone might stop to respond in some way. Use your Home-button to enter the springboard and run Terminal again.
DO NOT AT ANY POINT TURN OFF YOUR IPHONE, OR PUT IT IN DFU!!
Itīs important to keep in mind that when you exit Terminal, you will need to "guide it" to the path where iuenew is. When re-entering Terminal, write:
sleep (your option); iunew
I found it useful to put in 80 seconds, "sync" my start with a stopwatch and take good time to connect the A17 trace. I used needles and didnīt scrape the trace at all. I simply put the needle on the very, very side of the trace (a bit on the side and a bit on it) and applied some gentle force on it. Looked trough a magnifying glass to make sure where I was and connected to the capacitor with the other needle. This took patience and time, but hey, i had it. You should not do this unlock if you are about to hit the streets. After my time was up I held the needles for a 5 seconds extra, just in case.
After successfully getting the testpoint the process will finish of with the writing of the new bootloader. At the end it tells you to pray and write "bbupdater -v". Both times I got "baseband not responsive to pinging". After my experience, this is normal. Return to the springboard and put your phone in DFU mode.
Restore your firmware to 1.1.2! NOT 1.1.1!
Then you can restore again to 1.1.1. Continue with the guide from that point.
Notes on opening the case:
Follow the above guideīs tip of removind the black antenna-cover. Do NOT follow the guide when it comes to opening the rear case. This will surely leave the back with white stressmarks. I have one phone with them, and the last one i performed without a single scratch on it! Use a very small flat screwdriver and some (i used two) guitar picks. Not to hard, just a little soft (These will be broken at the end, but better them than your $450 investment). Put the screwdriver sideways in to the very side of the rear-cover, just at the side of where the bracket is. You will then be able to push the cover up a bit, enough to get a guitar pick in the gap, leaving the force of the screwdriver on the screw holding the chrome frame. Itīs a bit hard to explain, but if you read this while trying, you will understand. I will take a picture at my next HW-unlock. This is the strongest point of the rear cover, so you wont damage it.
I hope you found this helpful in any way, this is not something you should take ease on doing, if its not your daily job. If you have any more questions, leave them below and I will try to answer if/when I can...
