I've searched in web for screw guide/map for iphone 3gs but i didn't find anything.

can anybody make this?

i mean a photo that indicates each type of screws and shows the place of eeach one.

it's a weekness for this nice website that it doesn't have sth like this.

I also looked at iphone 3g pdf that shows screws but that was dumb.

Thanks a lot.

Plugging into computer gives 2 x "buzz" sounds and iphone is recognised on the PC but nothing on the screen. Completely dead in appearance

Here is everything I’ve tried and all the issues I’m running into:

• iPhone 3GS enters Recovery Mode normally (connect-to-iTunes screen).
• iPhone 3GS also enters DFU Mode (black screen).
• The phone definitely turns on — not dead or bricked.
• Cable and ports work; the phone is detected by Windows.
• Battery isn’t the issue — it charges and powers on.

• The latest iTunes version DOES detect the iPhone 3GS in DFU mode.
• But when I click “Restore iPhone…,” it immediately fails with this message:

• “This iPhone was previously in DFU mode, but restarted and is no longer in DFU mode.”

• So iTunes sees the phone in DFU, begins preparing the restore, and then forces the device to reboot — kicking it OUT of DFU before the restore starts.
• This seems to be a Windows 11 + modern iTunes issue where DFU mode is not maintained on older devices (3GS/3G).
• Older iTunes versions do NOT detect the device at all, which prevents doing a manual IPSW restore.

iTunes detects the phone but cannot complete a restore — DFU mode breaks instantly.

• The newest iTunes detects the 3GS but cannot begin a restore (DFU breaks instantly)
• Older iTunes builds won’t detect the phone at all

This makes restoring impossible on my current setup.

• Windows 11
• Using a 30-pin cable
• Using USB 2.0 ports
• Tried multiple ports and cables
• Apple Mobile Device Service restarted
• Drivers reinstalled through Device Manager

• Detects the iPhone in DFU mode
• But restore immediately fails with the “DFU mode restarted” error

• Does not detect the phone
• Stuck on Music screen
• Shows “The iPhone software update server could not be contacted.”

• Install fails with Error 7 (Windows error 127)
• Complains about incompatible Apple Application Support

I fully uninstalled all Apple components, in the correct order:

• iTunes
• Apple Mobile Device Support
• Apple Application Support (32-bit + 64-bit)
• Apple Software Update
• Bonjour
• iPod Support

Restarted the PC after each uninstall.

Reinstalled clean versions of iTunes, multiple times.

• Use Shift + Restore with the IPSW for iOS 6.1.6
• But since iTunes either fails to detect the device (older iTunes)⏎
  OR⏎
  fails mid-restore (new iTunes), I cannot reach a successful restore.

• A version of iTunes known to successfully restore an iPhone 3GS on modern Windows
• Whether Windows 11 simply cannot maintain DFU mode on legacy devices
• Whether I should be using:
  • Windows 10?
  • Windows 7?
  • macOS (older version)?
• Whether a custom IPSW or patched iTunes build is required
• Any known workaround or tool that allows restoring a 3GS today

I do NOT care about the data.⏎
I just need the phone restored to working condition on iOS 6.1.6.

I am no tech man when it comes to this stuff, but I have been working on it for hours on end.

Anything that might help, I will try.

I have an iphone 3GS with its power button not working.When I took out the phone after one year and charged it, I found the phone was stuck in recovery mode with a display 'connect to iTunes'. I tried all the procedures to come out of the recovery mode to bring the phone back to normal condition but to no avail, I tried a third party software Tenorware Share ReiBoot on Trial version. When everything seemed to be going fine, at the completion stage of software and firmware verification, alas, there came a pop out , that my iphone has a problem! And the operation got aborted.

Can anyone throw some light on this? Is it because of the non-function of the power button? Unless the button is set right or replaced one can not hope to resolve the problem?

I had Iphone 3gs 16GB and the ios was 6.1.6. It was from England and the carrier was O2. So for that I did the jailbreak and it was correct but after jailbreak it shows NO SERVICE. I asked lot of poeple and read some commentaries about that and I decided to Jailbreak again but also click "Install IPad Baseband" in redsnow. Then Jailbreak was going but It shows me "ERROR put your iphone..." in something but i dont remmerber "and then try redsnow again".

So after that It doesnt worked. I pluged in charge put show Chargong with red colour and shows Apple for some minutes and then sweaches off. I tried again but doesnt works.

The I went to Proggrammer and he told me that he must install Ios 4 , then jailbreak, then upgrade iphone to 6.1.6. He installed ios 4 and jaibreaked but in boot. So now my iphone is in boot jalbreak. I didnt sweached off my iphone because the proggrammer told me that if i do this my iphone will be die.

I wached that he cant do that and I decide to fix this by myself but only with your recommendation and good ways to fix my iphone.

Please help me in this.

Thank you for your attention!
