Hi. I would like to know if this procedure works to upgrade an iphone 4 from IOS 4.3.5 to IOS 5??? Thanks... JC

Hi, I have upgraded to 4.3.3 using this tutorial, everything worked as given. However, after using FixRecovery43.exe, I am not able to get out of emergency screen. Can any one tell me how to get out of emergency screen? Thanks,

Does this also apply to update to 4.3.3, I can see in tinyumbrella that my SHSH is saved for 4.3.3, my guess would be to say it is safe to do so. But I may be wrong.
youngplay - May 20, 2011 at 1:44am
I can confirm that this works also on 4.3.3

how did u get it to work with 4.3.1? Can you give us step by step what you did and where you get the files? Thanks

Is this method work for all future ios versions????
mikaljan - May 4, 2011 at 1:30pm
I can confirm that this works with ios 4.3.2 also, make sure you are running tiny umbrella in the back ground and have TSS server running!! The steps for upgrading to 4.3.2 without upgrading the baseband is the same as 4.3.1.
rolly - May 3, 2011 at 9:32am
Worked for me after trying loads of other sugestons...thanks!!

it seem like 4.3.2 is out but I like to keep my baseband so I am updating it to 4.3.1, the problem is that I am getting 16XX error which then I went back to step 5 but it like a loop getting the same 16xx error. I have TSS server running, and I try using Tinyumbrella 4.3 and 4.32 same problem. I also have try ignoring the error 16xx and ran the fix Recovery but I end up at the restore screen in Itune. I got this working before on another iphone. Anybody know what I am doing wrong?
RBrasil - May 24, 2011 at 5:37pm
I get the same loop. Let me know if you got an answer for this problem yet.

followed the instructions here, and successfully updated my iphone 4 to 4.3.1without the change to baseband 01.59.00. But how do I jailbreak next? I don't have Mac, but running redsnow will update the baseband again as far as I understand. Without JB, I can't run ultrasnow. HOW TO JAILBREAK?
blue2005 - April 11, 2011 at 3:23pm

thyago231 - April 10, 2011 at 8:48pm
No! Redsn0w will not update ur baseband!!!! Go ahead and Jailbreak and install Ultrasn0w, it fixed the bars not showing right...
ywu1012 - April 10, 2011 at 9:46pm
Good! But do you have to run Tiny Umbrella again while Jailbreaking with Redsn0w? Thanks!
thebrij - April 9, 2011 at 1:22am

thyago231 - April 5, 2011 at 10:59am
It Worked updating from 4.1 to 4.3.1 but only one bar showing... but voice/data seem to be fine... does anyone know how to fix the bar issue?
hebs - April 5, 2011 at 4:10pm
Ive just found this.... trying now. it was Tiny Umbrella stopping the Apple 4.3.1 update getting signed and seemed to stop the Baseband being updated. To fix the problem go into TinyUmbrella and in the Advanced preferences, unchecked "set hosts to Cydia on exit" and then restored by iPhone. Restore didn't force me into recovery and now I have full bars.
ashdas - June 3, 2011 at 6:43pm
what was the BB after the update ?
beks6 - April 4, 2011 at 7:54am

Marco - April 3, 2011 at 6:24pm

Awadh - February 28, 2011 at 10:38am
Hi, My iPhone 4, is running on iOS 4.2.1 with baseband 3.10.01. Will this procedure work for me? As I don't see any detailed note about baseband here in tutorial. Please help me. Thanks
viren - March 5, 2011 at 8:35am
Awadh, You are already on a higher baseband!!! this tutorial is for those who want to preserve 1.59.00 ....
Frank - April 3, 2011 at 2:29pm
yes, but this will keep him at 3.10.01

Mi Bear - April 3, 2011 at 5:59pm
IHave a iphone4 on 4.1(8b117) fw 2.10.40 will it keep me there.thanks much
mateen - April 3, 2011 at 6:11pm
Yes, it preserves any baseband
TT - February 18, 2011 at 10:46pm
I'm on (iPhone 3GS) baseband 05.15.04 with iOS 4.2.1 jailbroken. Should I just wait for a way to unlock 05.15.04 without upgrading to 06.15.00?
madcow - April 3, 2011 at 5:58pm
Well, this won't work for you it's for iphone 4 only. What you should do is wait for the untethered jailbreak to be released and an updated pwnage tool (or sn0wbreeze) then generate a custom ipsw and restore with that. That will keep your current baseband which is always a good idea even if it is not currently unlockable. NEVER update the baseband unless you are 100% sure there is an unlock OUT for it.
riceboy - February 18, 2011 at 8:14pm
I did the update recently and after doing it i get the insert valid sim and can't get the iphone4 to work anymore. is there any workaround? thanks!
YoGuy - February 16, 2011 at 11:38am
What does 'baseband' mean?
MINH CHI TRAN - April 3, 2011 at 2:46pm
baseband mean modem firmware.This should be work on modem firmware 01.59.00 without ypgrading modem firm ware. Thisdoesn`t work on modem firmware 02.10.04./03.10.01/04.10.01.Please carelly for this becuase some one use this and upgrading the modem fimware too
Tom - February 15, 2011 at 9:12am
Will this work same way for Mac since TinyUmbrella works on mac?
venkat - February 11, 2011 at 11:41pm
hi i have followed the same process it worked great. but after running greenpoison my phone stuckedup in emergency call screen top activate with official sim card. then i used redsnow to get that issue solved. and later unlocked with ultrasnow. worked like charm. but now am unable to use internet on my phone except wifi. does anyone have the smae problem.
DAGR8DON - February 13, 2011 at 12:36am
Im having the same problem..... Helpless and clueless....Can u give a detailed decription what u did... Even iTunes says that I need an official simcard to activate... HELP!!!!
venkat - February 13, 2011 at 5:28am
hi. after u r stuckup at insert sim card. just download redsnow latest version and follow the instructions by selecting 4.2.1 ipsw and then select install cydia. it will get u out of that emergency screen.
ViK - February 17, 2011 at 11:15am
Got the same thing as you guys described, stucked on the emergency screen. Downloading redsnow now and hoping to unlock my phone soon. When i finish it i will post the results, even about wifi thing.
ViK - February 17, 2011 at 2:27pm
So i did everything. Jailbreaking.. Needed redsnow to bypass the SIM activaction thing. Now I am stucked at Cydia, that just wont open, crashing when i try to start it. Any tips?
neonshad0w - April 3, 2011 at 3:10pm
??? The untethered jailbreak hasn't been released yet for 4.3.1, PROBABLY why it's not working...
Venkat - April 4, 2011 at 12:49pm
Hi am stuckedup previously when updating to 4.2.1. But i downloaded tethering and edit vpn settings apps from cydia. Just install them and u will see editing option in settings-general-network-mobile network Worked like charm. And no other issues from then. If anything else also worked for u pls post so that i will also get updated:-)
Thunderhawki - February 11, 2011 at 5:58am
Okay, so I usually don't have this kind of issue, but I've been trying to update my iPhone 4 for the last two days. I keep getting the following error message: "The iPhone 'iPhone' could not be restored. An unknown error has occurred (6)." What am I doing wrong? I read someone else note that their error was because of old itunes, so I just updated that. Still the error. TSS server is running, says the log... I'm stumped. Any ideas??
viren - February 10, 2011 at 9:18am
Hi SORRY the error is [0xE8000013] cheers
viren - February 10, 2011 at 9:14am
Hi Am on 4.1 with BB 1.59.00 on iphone 4 and am getting error [E0x800003] with tinyumbrella TSS running.... then I do the GreenPoison it runs EVERYTHING on my iphone including the greenpoison logo and then ....NOTHING the iphone returns as if nothing was ever done to it!!!! Running 4.1 on BB 1.59.00....NEVER seen anything like it!!! any tips??? Any help at all will be highly appreciated...cheers
William - February 10, 2011 at 2:38am
It worked great!!!! iTunes
macoy - February 9, 2011 at 10:11am
hi, i'm currently on a 3.10.01 baseband and 4.2.1 firmware, can i use this method to change my baseband? i'm not good at this.. help will be appreciated. thank you
Mansur - February 8, 2011 at 9:30am
Is there something similar to this for iPhone 3GS running on 4.0.2? Thanks
Jessica - February 7, 2011 at 6:35pm
Do you need to use TinyUmbrella if Cydia already has your SHSH blobs stored via the "make my life easier.." option within Cydia?
Crank_E - February 7, 2011 at 7:31pm
If you made youre life easier Cydia will gets the newest blobs as firmwares are released from Apple. If you want to upgrade firmware , then yes you must use tinyumbrella with the TSS server running to prevent the modem update piece. Then you will stay at the current baseband.
Vinstant - February 7, 2011 at 4:13pm
I ran this and had some trouble figuring out if I properly put my iPhone 4 into DFU mode, but when I did get up and running every thing worked perfectly! Just make sure you are running tinyumbrella all the way through the process. THANK YOU CHRONIC DEV-TEAM for all your hard and iClarified for posting this tutorial!
Crank_E - February 6, 2011 at 1:58pm
I ran this last night and it worked great. I had to kick the iphone out off recovery mode and then everything was fine. Updated to 4.2.1 and 1.59.00 baseband. Triple check making sure the TSS server is up and running in tinyumbrella. If not you will update your baseband.
wezz69 - February 6, 2011 at 9:39am
JBiG17 - February 9, 2011 at 10:30pm
I got Error 10 also at the beginning. The reason i was getting it is because i had an old version of iTunes. I updated to 10.1.1 and redid the process the update went through properly without upgrading the baseband.
Rounak - February 6, 2011 at 8:26am
Please tell us whether official SIM is required or not
Ron - February 6, 2011 at 9:21am
yes you need an official sim after you jailbreak it requites activation
mo3tasem - April 7, 2011 at 4:48pm
i need a way to unlock iphone with0ut official sim
BLITZNEP - February 6, 2011 at 6:08am
