[FIX SOLVED] How to Downgrade iPhone 3G/3GS Baseband 06.15.00 to 05.13.04 using RedSnow

iPhone Dev Team has released Redsn0w 0.9.14b1 that allows iPhone 3G / 3GS users to downgrade baseband from 06.15 to 05.13.04.
iPhone 3GS with basebands 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 can be unlocked using Ultrasn0w. iPhone 3GS with basebands 05.14.02 / 05.15.04 / 05.15.04 / 05.16.01 / 05.16.02 cannot be unlocked with Ultrasn0w so they have to install iPad baseband 6.15.00 on their 3GS device which can be unlocked. That was the whole story.
Now we have seen a lot of iPhone 3GS devices using 6.15.00 baseband to get the unlock. Once they upgrade to this baseband, it cannot be downgraded back to any earlier baseband. Now the question is why would they want to downgrade 6.15.00 as they are enjoying the unlocked devices on it ? Well there are few issues with the iPad baseband installed on the 3GS devices and GPS not working is one of the main issue. This is where the dev team is working right now and looks like they are very close this team for real. They will be able to downgrade 6.15 to baseband 05.13.04 or earlier version which can be unlocked without any issues.
This is what iPhone Dev Team has posted on their blog:

The iPhone Dev Team is happy to announce a baseband downgrade option in redsn0w for those who are using the iPad’s 06.15 baseband on the iPhone3G or iPhone3GS.
Typically you’d have the 06.15 baseband if you unlock with ultrasn0w but updated your iPhone baseband past 05.13.04. With this new capability, you can now downgrade specifically from 06.15 to 05.13.04 (even if you never had 05.13.04 on that device before). This gives you the best of both worlds: ultrasn0w compatibility and a normal iPhone baseband with full GPS and the ability to use stock IPSWs again.
Here are the steps:

1. Use the “Extras->Select IPSW” button in redsn0w to tell it which firmware version you have installed (new-bootrom 3GS users can usually skip this step but it doesn’t hurt for them to do it too).
2. Do a controlled shutdown of your iPhone (“slide to power off”). This step is very important to avoid mount problems when the ramdisk is running!
3. Go back to the first screen and click “Jailbreak”. Enable the “Downgrade from iPad baseband” checkbox, disable Cydia if you already have it installed, and click Next to proceed through the normal DFU ramdisk steps.

After the ramdisk gets launched and you see the Pwnapple running on your iPhone, you’ll eventually get to the “Flashing Baseband” step. THIS STEP TAKES A VERY LONG TIME to complete and there won’t be any feedback while its running. Please just let it be for the next 3-8 minutes! When the ramdisk has done its job it will reboot the phone on its own.
For those who are wondering if you can update your 3G or 3GS to 06.15 solely for the purposes of downgrading to 05.13.04, the answer is “yes” for 3G owners, and “maybe” for 3GS owners. The iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later. If you have an iPhone3GS and if digits 3-5 of its Serial Number are 134 or later (xx134…), then you should NOT try to install the 06.15 baseband on your 3GS! It will brick your radio, preventing both the downgrade from working and normal iPhone software from using it as a phone! Be warned!

[SOLVED] How to FIX iPhone 3/3GS/4/4S Charging Is Not Supported With This Accesorry Error

What I have to do if I cannot charge iPhone using a car charger, iPod charger or external wall charger

One of our readers tried charging his iphone using the ipod power wall charger and he was successful in doing the same, but many times he used to see the error on the iphone screen that this accessory is not made to work with iphone and iphone charging stopped every time, in order to fix this he used to unplug the cable and then re plug it into the iphone charging of iphone get started again.

One other reader who has been using a car charger most of time while travelling got this error when iphone does not charge anymore with its old car charger which used to work perfectly and still works with other iphone, but now it throws the error most of time when he tries to connect his iphone for charging from car battery using the old branded company car charger.

There are many methods to solve these kinds of problem occurring with your iphone, you can try the methods mentioned below as per the nature of your problem.

Fix Charging Stopped With iPhone Using Wall Charger or iPod Charger

In most of the cases this problem may occur when you are using the iPod wall charger which has a ipod touch or iphone style connector at one end and Power charger on the other end like the one shown in the video below.

Now when you are charging using ipod or wall charger using this kind of cable, you just need to unplug the cable and plug it back in after 1-2 seconds and most of the time you will see your iphone or ipad starts charging again. If you still see the iphone or ipad does start charging, try some other power port and it should work in most of the cases, still if it does not work then follow the solution below.

Charge Your iPhone Using A Universal Charging Adaptor and iPhone USB Cable

You can also charge your iphone any model from 2G to 4S or higher as well using Universal USB Power Adaptor and iPhone USB Data cable, for this you will need to buy a USB Power adaptor separately from your local market near by your place or you can look over some of them at this link [ ebay.in ] or this link [ amazon.com ] – Once you have go the charger you can connect the USB data cable with USB 2.0 port and other end will go into the iphone or ipad and then you can connect the arrangement to power port to charge your iphone.

Please Note: The USB Power Adaptor you buy should not give output more or less than 1 Ampere of current, as it then it might be able to charge your iphone or may throw more current that could be harmful for your apple device.

Please Note: [ I am suggesting this way as the genuine apple USB power adaptor comes quite costly in most the countries ]

[ALL TIPS] How to fix iPhone 3 GS White Screen of Death after repair

I had someone bring me an iPhone 3GS they had attempted to take apart (to replace the glass) by prying apart the chrome bezel from the back case. Needless to say, they broke several components in the process. I had to replace the dock connector assembly, the power/headjack/mute-toggle/etc. ribbon cable and vibrate motor. I also replaced the glass digitizer and LCD. When I power it on, I never get the apple logo, and it goes right to a white screen. If I hit the power/lock button it will go black screen. Hit it again and white screen. The mute toggle works (phone will vibrate), and iTunes recognizes the iPhone just fine. Holding home button will bring up voice control. I have tried swiping the digitizer screen to see if I can get some sort of audible response, but no luck. I have tried multiple new LCD and digitizer's, and same symptoms. I have even restored the firmware 3 times, no luck. Can anyone help? Here you have some of the available fixes: Anyway, a white screen usually entails a defect in the actual LCD or corrosion on either the connectors of the LCD or even the connectors on the motherboard. Use an alcohol swab and clean all the connectors (1, 2, 3 and the pins on the mobo), then dry them off very well with a can of air. And other tips in video tutorials: No1 No2 No3

Video Tutorial: Unlocking 3G/3GS with Jailbreak using Ultrasn0w for iOS 5.1.1 / basband 05.16.05 (also works with iOS6 / 05.16.07)

This is the best way to unlock, as it preserves your GPS functionality!

3GS: In this method, even if you're stuck on 05.15.04(unlockable), we can upgrade to the iPad BB, 06.15.00, and downgrade again past 05.15.04 to 05.13.04, so that you can have an unlock, and preserve your GPS!

3G: If you have accidentally upgraded to 05.15.04, you can use this method. You can also upgrade to the latest 4.2.1 iOS using a custom IPSW, so that you don't upgrade your baseband, then upgrade to iPad BB and downgrade again to 05.13.04. Make sure you don't upgrade using an apple IPSW, it could upgrade your baseband to something you don't want. I don't show you how to make a NO_BB file, pwn DFU, then restore with it, but it's quite easy, refer to link below for that.

WARNING: CHECK YOUR MANUFACTURE DATE, IF IT'S NEWER THAN WEEK 28 OF YEAR 2011, DO NOT PROCEED. EVEN IF IT IS OLDER THAN THAT DATE, YOU COULD STILL RISK BRICKING YOUR PHONE!! DO THESE STEPS AT YOUR OWN RISK, THEY CAN BRICK YOUR PHONE IF SOMETHING GOES WRONG DURING THE BASEBAND UPDATE.

This method of unlocking your 3G and 3GS requires that you have not updated to iOS6 and updated your baseband to 3.00.00. If you have done that, you cannot downgrade the baseband. If you have saved your SHSH Blobs, you can downgrade your iOS, but your baseband is stuck for good.

Now, here is the hardest part, if you dont really want to pay the service to factory unlock your iPhone 3GS with baseband 05.16.07, now let’s go with the painful process to unlock iPhone 3GS 05.16.07.

DO IT AT YOUR OWN RISK!!!

The rule before install or downgrade iPad baseband (you should stop if you are not eligible), Serial number should NOT bexx134 or later (you can check it on Settings → General → About, because the iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later. If your serial number shows xx134 or later and you still want to continue, youriPhone 3GS will be dead for sure.

Get every thing prepared. These are things you need to download.

1. iOS 4.1 IPSW firmware for iPhone 3GS. Why do you need iOS 4.1 IPSW? Here is a bit explanation: Apple stills signs iOS 4.1 (means that you’re still allowed to downgrade to iOS 4.1 without SHSH Blobs). Once you have iOS 4.1 installed on your 3GS, you must install iPad baseband 06.15.00, and after that you can downgrade 06.15.00 to 05.13.04.
2. Download redsn0w 0.9.14b1
3. Download TinyUmbrella latest version from http://thefirmwareumbrella.blogspot.com/
4. Download iTunes 10.4.1: Windows (32-bit) / Windows (64-bit) / Mac OS

Part II: Let’s start downgrading

You will need to remove your current iTunes and install the older version of iTunes (10.4.1) you have downloaded earlier.

1. Once done, open iTunes.
2. Put iPhone 3GS into DFU mode, and connect the iPhone into the computer. iTunes will say your iPhone is in recovery mode, click OK.
3. From iTunes summary page, HOLD DOWN SHIFT button (on Windows) or OPTION button (on Mac) and click Restore.
4. Browse iOS 4.1 IPSW file you have downloaded and click Open. It will takes few minutes to restore, just sit and relax and wait until the process complete.
   SenseiPhone.com confirmed that iOS 4.1 signing is wide open, BUT only for 3GS. So you can downgrade iPhone 3GS with any iOS version to iOS 4.1. We don’t know why iOS 4.1 is still signed and not iOS 4.2.1 nor iOS 4.3.3.
   Might be accidental or it has some other purpose that is unknown so far. But it works for iPhone 3GS only.
   In short: YES YOU CAN DOWNGRADE WITHOUT SHSH BLOBS to iOS 4.1 only (3GS only)

If you get iTunes unknown error 3194, remove gs.apple.com line from the hosts file.
If you get iTunes unknown error 1015, exit the recovery look with redsn0w “Recovery Fix” option.

Recovery Fix Option on redsn0w

Part III: Install the iPad baseband (baseband 06.15.00) to your 3GS

2. Click the Back button to go back to redsn0w’s main menu and click Jailbreak. Follow the instructions til you get here, where you can select options. Select Install iPad baseband and install Cydia options.
   

   Install iPad baseband
3. Follow the on-screen instructions, once the process complete, your iPhone 3GS will have jailbroken iOS 4.1 with modem version (a.k.a baseband) 06.15.00 installed as you can see on Settings → General → About.

The last part: Downgrade baseband 06.15.00 to 05.13.04

• Read here: How-to Downgrade Baseband 06.15.00 to 05.13.04. Make sure to select iOS 4.1 IPSW instead of iOS 5.1.1 shown on the tutorial.
• The step is actually the same as Part III, except you need to select “Downgrade from iPad baseband” instead of “Install iPad baseband“.
