Currently I am troubleshooting my iPhone 'sudden turns off after lock' issue. I found that it ONLY happens after I activated the phone.
My test log (using iLiberty+):
1. Restore iPhone with itunes and stayed for 1 day (no problem)
2. Jailbreak + unlock and stayed for 1 day (no problem)
3. Activate (problem comes out)
So now I wonder what the Activation does in both software and hardware part so that I can make sure it is hardware problem before replace one from Apple Store.
More information:
1. Refurb phone
2. Firmware 1.1.4
3. Baseband 04.04.05_G
4. Bootloader 3.9
Actions tried but problem still here:
1. Use other software like ZiPhone 3.0
2. Downgraded to 1.1.3
3. Downgraded to 04.03.13_G
Thanks.
