Den här guiden kommer visa hur du uppgraderar din Iphone 4 till iOS 4.2.1 utan att uppgradera baaseband med hjälp av TinyUmbrella för Windows.

OBS: Det här fungerar ENDAST med iPhone 4!

Steg ett
Ladda ned TinyUmbrella här ifrån. Se även till att ladda ned iPhone 4 iOS 4.2.1 som du kan hitta här.

Hur du uppdaterar IPhone 4 utan att uppgradera baseband (Windows) 4.2.1

Steg två
Dubbelklicka på den nedladdade TinyUmbrella.exe-filen.

Om du får ett windowsmedelande angående brandväggen, klicka i båda rutorna och klicka Tillåt åtkomst.

Steg tre
Var säker på att enheten är kopplad mot pc:n, och att Umbrella har identifierat eheten och dess firmware.

**Om du inte redan har sparat din iOS 4.2.1 SHSH blobs klicka då Save SHSH. Se till att den sparats innan du fortsätter.

Steg fyra
Klicka Start TSS Server och se till att du inte får några felmedelanden.

När TSS Server körs igång,kommer umbrella att stänga iTunes. Lämna TinyUmbrella öppen. Du kan klicka för att se att TSS server är igång under: Log-fliken.

Om du får något felmedelande, fortsätt INTE. Din återställning kommer inte fungera om TSS server inte kan startas.

Steg fem
Öppna iTunes genom att dubbelklicka på dess ikon.

Håll ned Shift tangenten och klicka Återställning

Välj din iPhone 4.2.1 firmware-fil från rutan som kommer upp och klicka Öppna.

Klicka Återställ för att börja återställa din enhet.

Steg sex
iTunes borde ge dig Fel 1013. Det här är vad vi vill, som noterat har inte baseband uppdaterats :) Klicka Ok och stäng iTunes.

Om du får ett 16XX fel, sätt enheten i DFU-läge och gå till steg fem.
Om din återställning inte slutar i en 1013, så har din baseband uppdaterats. Detta beror troligtvis på att inte TSS server var igång ELLER du uppdaterade utan TinyUmbrella ELLER du använder någon annan enhet än iPhone 4.

Steg sju
Sätt din iPhone i DFU-läge genom att hålla ned både hem och lås-knapp i tio sekunder, släpp sedan lås-knappen och fortsätt hålla in hem-knappen i 5 sekunder till. Du kan hitta hjälp med att sätta enheten i DFU-läge här.

Steg åtta
Du är nu redo att följa våran Greenpois0n-guide vilket kommer att jailbreka enheten och ta den ur DFU-läge. **Obs: Du behöver inte sätta enheten i DFU-läge efter att du klickat Jailbreak -knappen i Greenpois0n för det har vi redan gjort :)

Steg nio
Din iPhone kommer nu att ha 4.2.1 med 1.59.00 baseband! (Vilket betyder att du kan låsa upp operatörslås genom att användaden här guiden)

**Tack till semaphore för hans jobb på den här också!

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,

JF Gauthier - June 3, 2011 at 11:20am

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

Khoi Ky Pham - May 22, 2011 at 11:49am

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

as_usual150 - May 9, 2011 at 1:29am

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!!

Trickdaddy - April 22, 2011 at 1:19pm

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

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?

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

Saumil Bhavsar - April 27, 2011 at 5:48am

Fancyvpp - April 3, 2011 at 10:29pm
