iPhone Stuck at DFU Mode
Hey friends, I need a help here.
These days, my iPhone's 4 GPS has gone, it was able to get location only by triangulation/w
After a month without problem, the gadget starts to show the famous "white screen of death" (WSO) after the phone went to sleep state (screen became white when I pressed "power" or "home" button to wake it up). So, after restores, disassemblings and contacts cleans, I had the "great" idea to put it back in the oven (God knows the oven could fix this issue too...). Bad idea, now the iPhone is stuck in DFU mode. I tried to restore and didn't work, I keep gettin' "error 1600". Actually, iTunes shows the "preparing iPhone to restore" message (I got shsh saved since 4.1, so, I used Tinyumbrella), showing the server accepted the phone's request, but the restoration stops there. As I need the unlock (I live in Brazil), I can't directly update the firmware. I tried to update to a custom Sn0wbreeze current firmware (4.3.3) too, but iTunes shows the same error, even if I use iReb or Redsn0w to put it at pwned dfu mode.
So, the point is... did I brick my iPhone forever? I tried iRecovey too with no success (it says something like "invalid parameter"). Does somebody got any different idea? Even it involves complety disassemble the iPhone, I'll try it!
Thanks in advance!
It's been a while since the last time I post here! Well, sorry to say that guys, but the only solution I found was to change my phone to another one at Apple Store. I tried everything avaliable on internet, and nothing worked. But in my case, after some research, I discovered it was a hardware fault (more specific at the flash memory, the "oven trick" (as I said in the original post) burned the solder joints, making it unstable for a while and finally culminating in a unplugging of the flash memory from the mainboard). But my case was different from yours, there's an oven in the halfway that bricked the phone. But, if the problem persist even a restore, there are strong clues that's a hardware fault. So, don't worry your head too much: go to a store and change your phone!
If you are using a Custom Firmware (Snowbreeze is great) at 4.3.3 you must have the SHSH for 4.3.3 on your computer, if you want to use TinyUmbrella Server. SHSH for current firmware is easy to get as Apple will still send it to you. You can also let Apple Sign the current firmware instead if you want, but you will have to use TinyUmbrella Advanced Settings to Remove check mark regarding Cydia, because this is Blocking Apple from signing firmware or even sending SHSH to your computer.
The reason for the 1600 Error is that your iPhone is not truly in Pwned DFU Mode. Try again using those tools that put it into true Pwned DFU.
Also be certain you are using Sn0wbreeze 2.7.3 to create the Custom 4.3.3 IPSW, and make sure you let it put your iPhone into Pwned DFU.
My problem is I have 2x iPhone 4 and just after trying to upgrade them to they never ever get out of DFU mode, even when using the original firmware.
I have tried every resource there is on internet,
one of the Iphones is on 4.0.1 firmware and on an old base band, so I don't want to try to upgrade it to the last 4.3.5, I also have disconnected the battery so it will reset. on new windows, on mac. I have used old iTunes, old redsn0w versions, greenpois0n, just about everything.
it even updates and itunes dn't give any error, then
it kicks in DFU again. #$%^#$%^#$%^#$%
Please, Is there someone with the same problem that has an answer for me?
Thanks a lot.
Eu tbm estou parado nesse modo :(
E eu fui burro o suficiente de esquecer de usar o tiny umbrela! e agora nem voltar atras eu consigo
eu fui tentar atualizar para 5.0.1 preservando a minha bb mas na hora de sicronizar com o itunes da o erro 1600 ou o 1604
