Note: Do not put the iPhone in DFU mode with less than 20% battery

According to the errors that the update to iOS 5 has caused, which have been many more than ever, because there are many more iOS terminals than ever, we have detected that if you put the iPhone in DFU mode with less than 20% battery, you run the risk that neither redsnOw nor iTunes will detect the iPhone, for which we will believe that it has been hung and that it is in a loop (DFU loop). None of that, you just need to reload it and put it in DFU again.

Always remember to update and jailbreak with the iPhone loaded.

The other common errors have been error 3200, which is due to a server crash and error 3194 due to having the host modified (with TinyUmbrella surely).

    But doesn't the host need to have it modified with the Cydia server IP to install a Custom Firmware?

  4.   kanyo said

    No Juan, modifying the hosts file is to downgrade, that is, to download firmware as long as you have the shsh saved

    lol, how good the comment for a moment had seemed to me to read Joaquin Reyes, you have to tonticoooo, and I say, where does 20% come from? Because I have been restoring iPhones for 5 years, with 4% battery, recovery, dfu, ect .. precisely those modes are in case the iPhone does not have that 20% battery to be able to recover it, that is why it is called like that. Think, that if the iPhone has the 6.15 baseband, and you have restored it to official ios5, because you had forgotten to use a custom, it remains yes or yes in recovery, and in that mode it DOES NOT CHARGE

      If it is not a battery problem, what can it be ???
      My iPhone was low on battery power and I put it in dfu mode without being connected to the pc. From then on, the pc does not recognize it, nor can I get it out that way, dfu, what do you recommend ??? The same minutes later I jailbroken another iPhone 4 that was good on battery and everything was perfect. The only difference was that I put it in dfu mode connected to the pc, any ideas ???

    Let's not make things up. An iPhone can be restored in DFU even if it has been turned off at 1% battery, because the iBoot does not check the charge level, since you skip it.

    I just restored an iPhone 4 in DFU just shut down due to running out of battery. It has been restored, and when it has finished it was still not at 5% (here the iBoot is operational, not as in DFU mode), so the battery icon has appeared in red; When it has had the necessary charge, it has been switched on and configured quietly.

    Hello, I just want to know if I can charge my iPhone while in DFU mode so that itunes or redsn0w will recognize it because now it is downloaded and I cannot remove it from the DFU, it has damaged buttons and it only works again if I leave it for a few hours without connecting it. but if I charge it for pal of hours being in dfu mode it does not detect it.
