  1. **For anyone having problems with Windows, save the tsschecker to your desktop. Then open command prompt. Go to the tsschecker directory (desktoptsschecker). Then type tsschecker_windows -d iPhoneyour-phone-model-identifier-here-with-no-space -e your-euid-here -i your-ios-version-here –buildid your-buildid-here -s

  2. my iPhone isn't showing up in iTunes anymore for some reason. New iPhone (well its a 6s) but my others worked on my laptop perfectly. My computer recognizes it because it pops up and iPhone asks me to trust the comp but still doesn't show in iTunes. Any way to do this without iTunes?

  3. Hey Brandon I was wondering I can't wait any longer for a gamma release jail brake so I'm just going to do it now but my problem is what Yalu jailbrake do I get? Do I get beta 3 or beta 4 I'm running a iPhone 7 on 10.1.1 thanks!

  4. When i write sudo chmod 755 /users… it doesnt ask me for password. I can continue the tutorial and IT says shsh blobs saved… bit where? I can't find them…

  5. I am on iOS 10.1.1 on my iPhone 7 Plus but I want to reinstall it. It's really buggy because I downgraded from iOS 10.2 (while iOS 10.1.1 still was signed) and now all iCloud Services are not working properly. Is there a way to reinstall iOS 10.1.1 without updating to iOS 10.2? Thanks

  6. My guess is this only works on the iphone you copy the ECID from right? I won't be able to save the .SHSH2 blobs from one phone and then try to downgrade a completely different phone, correct?

    please help

  8. Common Problems & Solutions:

    – 'sudo' is not recognized as an internal or external command
    Solution: Sudo doesn't exist in Windows, so you'd need to either use 'runas' or just use methods 2 or 3.

    – How Do I start a conversation w/ the Telegram bot?
    Solution: Click the link in the description & the first button on that page says "Send Message"

    – [Error] [TSSC] ERROR: either device iPhone does not exist, or there is no iOS 14C92 for it
    Solution: Make sure you didn't add any extra spaces anywhere, pay close attention.

    – Build 14C92 for device iPhone8,2 (or variant) IS NOT being signed!
    Solution: Use the Telegram method. This is usually caused by multiple model numbers/chips like the 6S and won't save if you don't specify in Terminal.

  9. Dear Brandon, thank you for this, method 3 was the only method that worked for me. (Maybe my error). Question: These are blobs saving for IOS 10.2, but will these assist me in downgrading to an earlier, unsigned version say 9.3?

  10. For the people having errors I had the error

    "can't unambiguously map model to boardconfig for device iPhone8,2
    [Error] [TSSR] cant find boardconfig for device=iPhone8,1 please manuall use –boardconfig
    [Error] [TSSR] Error: could not get id0
    [Error] [TSSR] failed to build tssrequest

    Build 14C92 for device iPhone8,2 IS NOT being signed!
    I tried all of the methods and had the error but method 2 (Telegram) it gave me a message saying to specify the board config and suggest me to download a app to the iPhone called BMSS once you open it go to system and it would say model after do the first method again and at the end after -s type –board config and the model I have a iPhone 6s Plus IOS 10.1.1 I hope it works for you as it did for me.
