I would like to add something:

For some who are in 4.3.5 and who restore in 4.3.3 and who have a problem with the fix recovery, which does not change anything, there is a trick, but you have to go back to 4.2.1.

Prerequisites:

-Itunes 10 mini-iphone 4.3.5 or lower-TinyUmbrella-SSH: 4.3.4, 4.3.3, 4.3.2, 4.3.1, 4.3 and 4.2.1

1) Launch TinyUmbrella 2) Click on Start TSS Server 3) Put your iPhone in DFU mode 4) Launch iTunes 5) Restore in 4.3.4, you have error 1013, ignore it. 6) Return to DFU mode 7) Restore in 4.3. 3, you have error 1013, ignore it. 8) Return to DFU9 mode) Restore to 4.3.2, you have error 1013, ignore it. 10) Return to DFU11 mode) Restore to 4.3.1, you have error 1013, ignore it. 12) Return to DFU13 mode) Restore to 4.3, you have error 1013, ignore it.
