Does anybody know details on how semaphore does a TSS downgrade of an [[K94ap|iPad 2 (GSM)]] firmware, without modifying the baseband and without running into a recovery loop? (see [http://cl.ly/2i151c3x1C3z3W2i0l0q this screenshot]) The latest TinyUmbrella release supports such downgrades and there is no bootrom exploit that would allow a kick out of recovery. I thought such a downgrade is possible by getting the [[SHSH]] from the local backup and the baseband SHSH from Apple (because of the nonce problem). As long as Apple signs the same baseband, even a baseband downgrade from an iOS5 beta baseband would be possible. Or, in the more common case, a complete restore from iOS 4.3.4 to 4.3.3 (including baseband). But TinyUmbrella doesn't even try to change the baseband, so his method must be totally different. He also twitted me "it is WAY more complicated". Anybody knows more? --[[User:Http|http]] 06:13, 20 July 2011 (MDT) |

Didn't he used to support Linux? --JakeAnthraX 19:59, 7 May 2011 (UTC)
- Not that I know of. --Balloonhead66 21:56, 15 July 2011 (UTC)
- The JAR file is in the Mac .app file (right-click>show package contents), wouldn't that work (sortof) with Linux? --rdqronos 20:02, 18 July 2011 (MDT)
Restore / downgrade iPad 2 GSM without baseband
Does anybody know details on how semaphore does a TSS downgrade of an iPad 2 (GSM) firmware, without modifying the baseband and without running into a recovery loop? (see this screenshot) The latest TinyUmbrella release supports such downgrades and there is no bootrom exploit that would allow a kick out of recovery. I thought such a downgrade is possible by getting the SHSH from the local backup and the baseband SHSH from Apple (because of the nonce problem). As long as Apple signs the same baseband, even a baseband downgrade from an iOS5 beta baseband would be possible. Or, in the more common case, a complete restore from iOS 4.3.4 to 4.3.3 (including baseband). But TinyUmbrella doesn't even try to change the baseband, so his method must be totally different. He also twitted me "it is WAY more complicated". Anybody knows more? --http 06:13, 20 July 2011 (MDT)
