I think its important to update you about iOS 5.0.1 install issues using latest redsn0w 0.9.10b2 on Windows for iPhone 3GS having iPad baseband 06.15.00. Read further how I spent a FULL day without any success and only 30 minutes today with success.
First of all, not all of you may face this problem but I surely did and some others would. They might try too many things since they’re unable to install and may look for some solution.
To begin with – here is a preparation I did before trying for an update.
- Saved SHSH Blobs for my iPhone 3GS with 06.15 baseband using TinyUmbrella on Cydia server. Cross checked if they’re stored successfully.
- Backed up my iPhone using old iTunes 10.2.2
- Copied my backup from c:Documents and SettingstusharApplication DataApple ComputerMobileSync to C: drive
- Clean Uninstalled iTunes 10.2.2 to including all the folders, registry and also removed AppleMobileDeviceService to avoid error 1601 & 1602
- Installed latest iTunes 10.5.2.11
- Created a folder on desktop for iOS 5
- Downloaded & extracted the redsn0w_win_0.9.10b2 in this folder
- Downloaded Stock IPSW iPhone2,1_5.0.1_9A405_Restore and stored in the same folder
How Actual Process took place
After setting up myself with all the required files etc, I began with redsn0w and the first step was to create a custom IPSW so that it can save my baseband for unlock.
My iPhone 3GS is definitely not from new fixed bootrom series so I clicked NO for question asked by redsn0w prior to create custom BB iPSW. After it finished creating a custom IPSW – redsn0w named it to NO_BB_OLDROM_iPhone2,1_5.0.1_9A405_Restore. This was nice, so that I could find my custom IPSW easily.
Now, before I install this from iTunes – I had to put my iPhone in DFU mode. To do this I selected Pwned DFU from redsn0w and successfully managed to put it in DFU mode with black screen.
Since my iPhone was in DFU mode, which is perfect for restoration, I opened iTunes and it could detect 3GS in restore mode then I selected NO_BB_OLDROM_iPhone2,1_5.0.1_9A405_Restore.ipsw by clicking SHIFT+RESTORE
iTunes went ahead with the upgrade process and successfully installed custom cooked iOS 5.0.1 which was jailbreaked by redsn0w while creating it. I was getting excited to see this new version when iTunes prompted me about my iPhone will reboot in ten seconds.
Then I tried using a JUST BOOT method from redsn0w as described by Dev-Team but I kept getting identifying IPSW error. See image along.
I kept waiting and my iPhone could not reboot. *BUMP*
I tried all possible methods to get my phone rebooted including kicking it out from recovery using various tools, using home + power buttons for several times etc. But, my phone never woke-up!
I started getting frustrated, worried too because I was not carrying any other phone yesterday and hence had to bring my iPhone running. But, I had to give up 🙁
What happened after this?
Then, while in search of a solution, I found on Dev-Team blog that – we’re not supposed to redirect gs.apple.com from host file to Cydia server in order to install iOS 5.0.1 which otherwise we were doing as mentioned in 4.3.3 Install Tutorial. It clicked me like a perfect solution only to get disappointed further in my case.
I tried installing iOS 5.0.1 several times using custom IPSW after I changed my hosts file, but as I said – my phone remained in black screen DFU mode. iTunes however was showing my iPhone software is up-to-date.
Few guys helped me by answering to my queries but I knew my situation isn’t the same they think it is.
After a good night’s sleep with my sleeping iPhone, I remembered something 🙂
I had saved my custom IPSW created for 4.3.3 using sn0wbreeze – the same which I mentioned in a 4.3.3 custom install and jailbreak tutorial here. I felt like I am a proud owner of this IPSW and thanked @iH8sn0w for giving us sn0wbreeze last time
I quickly jumped to iTunes thinking my iPhone is already in DFU mode showing just the black screen. And selected sn0wbreeze_iPhone 3GS-4.3.3.ipsw using SHIFT + RESTORE. A few minutes later got 1601 error.
I was wrong. So, I opened newly downloaded and went to redsn0w 0.9.10b2 > Extras > and selected Pwned DFU to make sure my iPhone is in DFU mode. Then, opened iTunes and started with Shift+restore process for downgrading from iOS 5.0.1 to iOS 4.3.3 using latest iTunes. I was skeptical for few minutes.
AND looking at the sn0wbreeze logo on iPhone brought huge smile on my face but I was still not jumping much because the problem was not about installation – it was about rebooting after the process…
AND Voila!!! My phone rebooted after iTunes prompted me it will. This is something was not happening on my iPhone while installing iOS 5.0.1.
I finally managed to downgrade my sleeping, semi-dead iPhone from 5.0.1 to jailbreaked 4.3.3 preserving my baseband 06.15.00. After quitting iTunes once my phone was detected well, I quickly re-copied my backup as mentioned earlier to c:Documents and SettingstusharApplication DataApple ComputerMobileSync – started iTunes to see Restore from backup option.
I was happy and jumping to see this option and managed to restore my backup as well.
OLD is always GOLD.
iPhone 3GS with jailbreaked iOS 5.0.1 using redsn0w is having few issues to get untethered jailbreak, varied from person to person and iPhone to iPhone. Some also report they have bricked their phone since GPRS, 3G and WiFi are entirely missing from their phones.
Now after restoring back to 4.3.3, I am feeling lucky not to see rebooted iPhone similar to those guys…
I am writing this entire story here to help you guys just in-case you’re looking for a suggestion, solution for installing iOS 5.0.1 using redsn0w. I wouldn’t blame to anyone but it could be happening entirely for me if I have made any mistakes…
The world doesn’t end here and we all know Dev-Team members are extremely talented which is how I could eventually revert back to usable iPhone. Lets wait to hear from them if such issues are already on their roadmap.
If you don’t face any issues, you’re lucky but if you do then, I will definitely update you guys right here for more. Hope this helps 🙂
