3Gs in White Screen

[dark_drakko]

Hi, I don't know what anymore to do with a 3Gs. Yesterday my friend gave me his 3Gs because had broken screen. I replace it for a new one and then restore it with Saved Blobs to v4.3.3, for now everything working great. He ask me to unlock the iPhone, but the only way is by IMEI Permanent Unlock, so I buy the service on the internet and they unlock the iPhone. I check the IMEI and it says that is unlocked. Ok, so yesterday before the unlock, I restore it to v4.3.3 with a custom ipsw and jailbroke the iPhone as well. I leave it all night in my desk and this afternoon when I take to insert the new SIMcard, I notice that the screen is all black and won't turn on. I tought that is a battery dead so I connect it to my wall charger dock and leave it right there for about 3 hours. After that I go to check the iPhone but the screen still black. I just connect it to my iTunes and it say that is in Recovery Mode. I said, easy just load Redsn0w and try to just boot tether right now but stay in White Screen. I force it to DFU Mode again and try the Fix Recovery 4.3 but stay again in white screen. I give up and decide to restore it with iTunes to v6.0 and guess what, White Screen again and iTunes say Waiting for iPhone...

I don't know what else to do. Please if someone know how to fix this, please let me know.

The iPhone is on v4.3.3 and is Unlocked by IMEI, is a 3Gs of course with a 16Gb.

Thanks

same thing just happend to me ! :/ Freaking Iphones ! -_-

Try a iTunes restore and look at the Update log if there are any errors. This will give you a little bit more information about your 3GS.

Defiantly try DFU mode. Make sure your iTunes is up to date. Commen problems with white screens is that the LCD connector is not completely seated. Also when going to ios6 make sure your host file is not set to cydia. Good luck

Ya but regardless of the screen being attatched or not it should still restore to ios6 but it dont. Just says waiting for iphone....

[Nory]

there's 2 fix for this problem !
1st- is to disconnect the logic board from the battery for around 2hours than restore again ! this will force a HARD reset!
2nd- wait for the battery to completly drain ! ( this i'm trying myself now ) i have the same problem as yours !!

That reminds me of some problems I had before. For some reason it would not install the drivers properly. I had to uninstall the drivers for the iPhone while it was connected restart my pc. Then I put the phone in recovery mode and it installed the driver and then in DFU and installed a differen driver. Then it worked

Make sure the phone is charged and that the #4 connector is seated properly. That is the connector it uses to sync with the pc. I have had some that would charge but not sync because it was not properly connected.

Did your battery drain test fix your iPhone...? I will try to disconnect the logic board and let it rest for 2 hour or more to see if this fix my issue.. Please let me know.. Thanks

Hey guys, I found this in another forum and copy-paste it with the hope it helps
Reports are that it worked
I haven't tried it myself
Do it at your own risk

READ THE WHOLE THING FIRST!!!

"Getting white screen of death on your iPhone 3GS? Error 28? Read on.

If you ever tried updating your iPhone 3GS from iOS 4.x.x to iOS 5.1.1 while on 06.15.00 iPad baseband, there is a chance you had to deal with tons of issues when "by accident" selecting the wrong bootroom when creating the custom IPSW.

Selecting the wrong bootroom at the creation of the IPSW and then "force restoring" your 3GS to that firmware creates a trunk load of issues that include:

1. Error 28 - many times used to identify the "connector" issue.
2. White screen of death. Just can't get out of it.
3. Numerous errors in iTunes (when trying to re-restore thinking that that will fix the problem 1, and 2).

The truth of the matter is if you have experienced any of those issues the possibility of restoring to Apple's stuck firmware isn't available ether. Your phone stuck in a limbo mode referred to as "bricked state".

There is a way to get your phone back to life. Don't freak out although it is easy to do at first.

Today I would like to share with you how I was able to get my phone back up and running without any issues.

Originally, my iPhone 3GS was on 4.1. I've decided to upgrade by creating the custom firmware (5.1.1). The tricky part was when I looked at my serial number... according to it, my 3GS was created on the 12th week and was considered as having the "old bootroom". I never bother with checking what bootroom I have with tools like redan0w or others out there. Which is where it all went wrong.

After creating the IPSW, I have successfully restore my device to 5.1.1. It worked for about 15 minutes and then I got a black screen. After "force reset" my phone booted up into the white screen. From there, all hell broke loose. I've started to get errors I never knew existed (< exaggeration, but you get my point) including the hardware failure error 28.

Nothing worked. I had success putting my phone into the pwndDFU with redsn0w, but it simply wouldn't restore.

Here is what I did to make my phone work. I do have to mention this though, the method described below is not an encouragement for you to do this. I am simply sharing what worked for me and am not responsible if you brake your device.

1. Taking the iPhone 3GS apart. Yep, you read it right. The purpose of this was to disconnect the logic board from the battery for about 1 hour.

There are many tutorials on how to take your 3GS apart on YouTube. Please search there. This tutorial is focused on a software fix.

Keep in mind though, disconnecting all the connectors and leaving the logic board screwed to the back case doesn't count. I actually had to completely take it out as there is no way to disconnect logic board from the battery without unscrewing it completely.

I waited for about 1 hour before I started to assemble it back together.

2. While waiting, create a new custom IPSW with the "new bootroom". You can triple check your bootroom (new or old) with redsn0w. Extras > Even more.

Important: I was updating to the 5.1.1 (which is the current iOS version signed by Apple) I didn't stitch the firmware (with redsn0w) as there is no need. In the future, stitching will be required (when apple releases a new update and no longer signs 5.1.1).

Important: Make sure your "hosts" file is not pointing to Cydia. To check if you have it setup properly, visit this page in your browser: http://gs.apple.com. If you get Cydia's page, you need to change a few things in your "hosts" file.

- Navigate to /etc/hosts (Mac, don't know where it is on Windows)
- Open hosts file in TextMate and add "#" in front of any domain ending with .apple.com.
- Save the file. Test the gs.apple.com in your browser. You should get Apple's 404 page.

If you get Apple's 404 (not found) you are good to go.

Advice to those who follow: Don't bother with TinyUmbrella at this point. You don't need it. Starting with the iOS 5, TinyUmbrella is useless unless you want to downgrade to iOS 4.x.x.

3. Assemble the iPhone without braking anything. Now this step is super important. After, refer to step 4 quickly!

4. Connect your 3GS to a mac and launch redsn0w. Go to "Extras" and hit "Pwnd DFU". After about 15 seconds redsn0w will inform you that your device is in pwnd state.

5. Launch iTunes. Again, don't bother with tiny umbrella. It might be the reason for 16xx errors. Press "Shift+Restore" and navigate to your NO_BB_NEWROOM IPWS. This time, you should be able to restore.

When your device is restored, you can relax. Everything went well.

6. At this stage, your device wont be activated. Absinthe jailbreak wont work. You will need to jailbreak with redsn0w. Do so.

7. After the jailbreak process completes, make sure you go back and "boot tethered" from redsn0w because the jailbreak will be tethered (will fix in a minute).

After your device is booted "tethered" open Cydia and install Rocky Racoon. This package will untether your device.

8. If you are a unlocker, install ultrasn0w. Then add this repo: repo.iparelhos.com and install 5.1.1 ultrasn0w fixer.

If you get "No Service" still, don't worry. There is a simple fix for that.

If on T-Mobile, make sure to turn off the 3G in Settings > General > Network.

Open redsn0w again and hit "Jailbreak". Yep, re-jailbreak. This time, when you get to the screen where it asks if you want to install Cydia, make sure you have it UNCHECKED and install the iPad baseband CHECKED! This process will simply flush the baseband.

Unfortunately this process will require you to "boot tethered" again and reinstalling Rocky Racoon package (to make your jailbreak untethered).

So there you have it, those are the steps I did and now I have a perfectly functional iPhone 3GS on 5.1.1 with iPad 06.15.00 baseband on T-Mobile.

Thanks!"

That's the only thing I found that was reported to work.
So, now you know which scenario applies to you (if you're not on iPad BB, if you're not on new bootrom, etc).
All the answers you might need from this tut are answered in the forum, use the Search button or ask here if you just don't find it.
In case it worked for you, use this thread for BB Downgrade

I try this that post navarhos and worked for me. I just disconnect all iPhone completely and let it rest for about 3 hours, then assembly again and with redsnow use the dfu mode and restore to iOS 6, the first 3 attempts gave me an error (-1) (3804) (1600) but later I change the computer and restore it to iOS 6 and worked..!!!! Now the iPhone is completely functional. Thanks a lot for your help, Sinful iPhone... the best iPhone Forum...!!!!!!!!!

Excellent man !!! I know it's a daring choice to do what it says, but if it's the only one that works you gotta do it. Great job
