How To: Downgrade iOS 5.1 To iOS 5.0.1/5.0 On iPhone 4/3GS, iPad 1G, iPod Touch 4G/3G

thanx a lot   
  its working 101 %

where is it for mac version?

Worked for me as well. I used this guide to actually upgrade from iOS 4.3.3 to iOS 5.0.1. before this I kept getting error 3194 “This device isn’t eligible for the requested build.”. this was due to Apple has stopped signing iOS 5.0.1 I think. custom firmware I buld with sn0wBreeze didn’t restore either but this guid worked great. thanks very much

is there anyway i can downgrade 4s? please!! =(

so do i, i didnt save shsh on 4.3.3 and 5.0.1, what should i do?

WOW ! It works !

Thank you !!

I Had the same problem then i jailbroke my ios 5.1 and cydia had a saved SHSH blob so what i did was that i used tinyumbrella to save the 5.0.1 shs blob and then followed the steps above. hope this helps

you can´t downgrade to a older version like 5.0.1
you have to wait for a jailbreak on 5.1

 This thing worked perfectly for me !! Thanks a lot !

how can i jailbreak ipod touch 4g … i downgraded but while using redsnow 0.9.10b5c and also 0.9.10b6 to jailbreak it doesn’t jailbreak plz help me

Dík moc byl to boj, ale úspěch se dostavil.. ĎĎĎ

 i thought that too. if you had cydia before, the download tiny umbrella and click there “save SHSH” (something like that) then it will show you all your shsh blobs. if you didn’t had cydia ever, then you’re screwed

Downgrading from 5.1 to 5.x, also works using redsnow, if you’re on a mac.  (provided you’ve saved shsh blobs and APticket.)  Just open redsnow, and stitch a 5.0.1 firmware with your shsh blobs and APticket that you saved.
Then open redsnow again, and get into pwned DFU mode.  Option-click restore in iTunes, and select your custom firmware you just created.
Let it do its thing, and at the end most likely you will get: “error 1, this iphone could not be restored, an unknown error occured.”  When that happens, open redsnow and click “fix recovery” and follow the directions (it will tell you to enter DFU mode again” then it will exploit with limerain, and when its done, you will be on 5.0.1!
No tinyumbrella, or ifaith needed.  Redsnow and iTunes are all you need. 

This delets all I have in version 5.1 ?

thank you it worked !!!

ifaith created  the custom firmware file and i also did the DFU procedure but when i open up itunes and click on shift and restore, i have to select a file which was said to be on desktop but i don’t have any extra files on my desktop, not sure what to do now. please help.

My friend as an iphone 4 5.0.1 can i use his saved SHSH blobs on my iphone 3gs on 5.1?

u can downgrade a4 devices with shsh blobs, but u can never downgrade a5. so downgrading 4s to ios 5.0.1 is a no no. If you do have ipad 2 with shsh blobs saved for ios 4.3.3 then gr8 for u

can some one help me? i to downgrade and it says 5.0.1 but there is no cydia .. i have ultrasn0w + 5.0.1 ipsw but it gives me a error if some on can please add me on skype: Flamerulerz

ok thats good boss….i got it……  thankuuuuuuuuuuuuuuuuuuuu….

Hey guys, I currently have my iphone 4 jailbroken on ios 5.01, it entered a recovery/respring loop and it’s been impossible to fix (I’ve mainly been trying to shift+restore the 5.0.1 custom IPSW I saved when I jailbroke it, but I keep getting itunes errors). I’ve been thinking maybe I should re-jailbrake to 5.1 and then downgrade back, however I HAVE NOT backed up the blobs on my computer (they are on Cydia but since I’m in the recovery loop I can’t get them). If I run tiny umbrella in it’s current state, the iphone (and blobs) doesn’t show up, I’m wondering if I upgrade, re-jailbreak in 5.1, and THEN run Tiny Umbrella, will the old blobs show up? I’m thinking they should as I’ve had Cydia for over a year, but I don’t want to mess up and end up with a tethered jailbreak I can’t get out of… Any suggestions? Thanks!!!

what about error 10 no one is talking about tht
 

same here need help please.

No…Blobs are device specific!!

So guys I also had some problems downgrading my iTouch 4 from 5.1 to 5.0.1, but still I managed to fix it now: SHSH Blobs are necessary, so use a shsh blob from another iTouch with iOS 5.0.1 and save it using TinyUmbrella, then use iFaith to search the file and follow the instructions above. Without shsh blobs you can’t downgrade it :/ or jailbreak the iOS 5.1 and save your shsh blobs when cydia is installed, again use the instructions from above! Hope this helps.

Hi, it doesn’t work for me.
I saved my shsh using tunyumbrella before upgrading to 5.1 by mistake.
I followed the instruction but when i select the 5.0.1 (9A405) firmware it says:”INVALID 5.0.1 (9A405) ipsw for the iphone 4!”

What the hell is that!!!

Yes, i selected the right fw for the same shsh i saved

iphone 4s 5.1 downgrade 5.0.1  ?

so i had 5.0.1(jailbroken) before and yesterday my ipod 4g updated to 5.1 and was stuck in recovery mode. i was wondering is it possible to still get my 5.0.1 shsh blog from cyndia or am i screwed
 

Hello iJailbreak

I have downloaded to iOs 5.1 not knowing it is an iOs which dosent have jailbreaking options on it. I am planning to use your method but I want to know 100% that it is completely safe, and will not cause any viruses as I will be extremely mad and stressed out if it will do anything unusual to my computer. I have all of the listed things and am ready to do your method though the health and safety conditions must be good. Please answer back soon

got an error “1600″ on an iPhone 4?  any idea on what 2 do?

Thank u sooo much!!!!!!!!!

a zillion downgrades, but this one works and simple. thanks1

Step 5, after browse firmware you want to downgrade then press “download it for me”?

I have everything , SHSH files and my phone is 3Gs on 5.1 now and i wanna go back to 5.0.1. I did Exactly the same as the Steps showing above. But the Error 1600 is just annoying me. Can anyone help me out with this error ? Thz 

can it work on 4s?

Everything was successful till the itune restore. Keep having the error of restoring iphone in itunes error 1602-1604. Tried windows 7, error 2005? Any help?

Did everything right, but it just goes back to recovery mode when its done with no errors. So confused.

does this works for the iphone 4s?????

my friend has iOs 5.1 on his iPad mine is iOs 5.0.1 can i use my SHSH BloB file to his?

i havent saved my shsh blobs for iOS 5.0.1 and updated to 5.1
can i save the blobs for 5.1 and then downgrade to 5.0.1
will it work??

it gived me an error 37

 sorry pare dapat may save ka talaga na shh..

Done,, I’ve already downgrade my iPhone 3GS from iOS 5.1 to iOS 5.0.1. Thanks for your information.

hi,
is there anyway i could stop ios 5.1 download other than disconnecting WiFi? because whenever i connect the download starts. i have a 4s.

 I had in my 3gs the 5.0.1 jb and unlocked, so my cellphone is currently kinda bricked because it doesent get the network… anyone knows if can I do something?, I have the shsh files.

so if you have an iPhone 4, that has been upgraded to 5.1, where does one fork fond the blobs and is it possible to downgrade?

 pare na update ko yung ipod ko sa ios 5.1 na naka jailbreak ako ngyon na nag break yung ipod ko pero na irestore ko sya nawala lahat ng games and files and music ko.pano ko magagawa idowngrade sa 5.0.1 ipod ko?

what r u trying to do with ios 5.1 with ifaith it is made to build older firmware versions not the current if you are trying to save them than use tiny umbrella

you can find out a way to do it to your 4s online somewhere just search on google

me2 we’re all screwed thanks to itunes

 help me! how to out pwned dfu state

how did you that

 I had all but given up on my 3gs on 5.1! Mine’s the old bootrom version so I updated to 5.1 to use the untethered and ultrasn0w fixer for 5.1 but it didn’t work out. This post eased my frustrations! Thanks a lot Bro!

NO

you either get them when your signed or you don’t get them at all, simple as that, (have to get them when the firmware is fresh and live) not when its stopped being signed by apple

he followed the instruction? this is a off basis question

perhaps follow the instructions posted by ifaith?

same here, thanks for your reply, made me feel good and secure to do it myself too

nope your SOL until 5.1 jailbreak untethered comes out, sorry man

if you want to save it too you have to also make a file that will save your BB as well, I believe you had to run it through redsnow first then stich your ipsw file with ifaith to restore, (google it I recall seeing a method for you)

perhaps bad SHSH’s files?

 glad to hear, just like me, although I got it on the first try

bad SHSH for sure

from tinyumbrella, google a tutorial for it, it will walk you through it

you SOL , please understand your going to have to wait till a 5.1 jailbreak thats untethered comes out, sorry man

great to hear your back up and running! I did my iphone 4 without issue, even on the first try. 

no your good to go, grab them with tinyumbrella, once you have them from there you can cook up your own custom firmware with this guide at the top of the page, as long as you have an iphone 4 like you say you do, then your good to go, as well you actually saved your SHSH’s to cydia’s servers 

 bad ipsw file, download from a different sorce,

read the above comment

which device did you restore (others might be wondering like me)

why not grab them from cydia servers via a tool called tinyumbrella, google it and it will tell you how to do it, simple then you can come back and use this method to restore

bad shsh’s blobs sure you got them for your device?

OMG your SOL if you didn’t save them tired of writing this!

did you make your IPSW file with Ifaith? did you even read this guide or did you scroll down and just skim through it, I am not typing any further here

yes it will, save everything and then do this method, good luck

check if your device has any with tiny umbrella 

on what device?

put the device into DFU mode, do a google search for the method

NOOOOOOOOOO your SOL without them if you had them at the top of cydia saying 5.0 or 5.0.1 then you can grab them from cydia with tiny umbrella then use this guide to restore hope that helps

on what device sir?

on what device did you do?

pare bakit ganun na stuck ako sa recovery mode

can you downgrade and then restore from backup and have everything from when you had ios 5.1? 

i must have done something wrong as my phone wont work.
ive tried everything even downloaded sn0wbreeze and found the thingy i wanted there but once itunes extracted my iphone it then said it cant work and now my phone is stuck off and broken HELP!!!!

Oii,nao estou conseguindo rebaixar o meu iPhone 3Gs,pois quando vou em restaurar durante a restauração da varios tipos de erro 16xx,21 e mts outros,Alguem me ajude

how do i upgrade my i touch 4gen which is jailbroken with a ios 4.2 to ios 5.0?

WORKED LIKE A CHARM. THANK YOU

what about Ipad 2 please

Apple is still signing iOS 4.1 you can downgrade to it with out the blobs.

 No. They are unique for each device.

it is a good idea to save ur 5.1 blobs

 i believe ios 4.1 works without shsh blobs.
try it.

anyone know when untethered version of 5.1 jailbreak comes out?

Man, don’t be rude, he just wants information….at least have the attitude to behave and give a little as the developers give us their sources.

i have iphone 4 IOS 5.1 i want to downgrade to 5.0.1 but i want to
preserve my baseband actually is 03.10.01 how can i do that? becasue i
dont have shsh in this iphone? but i had another iphone that i saved it
can i use it those?

excellent article !!!!!!! i am successfully restore my iphone 4

so i will have to restore it?

Finally, something that works! Thank you so much.

IT WORKS, THANK YOU SO MUCH!!!!!!!!!!!!!!!!!!!!!!!

version for mac? 

i dont have any saaves shhs blogs what do i do

Dumb Question?
I have my SHSH blobs but no aptickets for 4.3.5 or 4.3.3
I have tried to down grade using this method but It seems to only be good for downgrading software, not baseband…
can I downgrade baseband without apticket?

thx this worked on my iphone 4

i have an ipod 2g will this program work and if it fails is ther a backup file

Wooo Hooo this worked…thank you very much.!.:)

like the guide says, you need a windows computer. There is no way (until iFaith comes out with a Mac Version) to do this with a Mac.
…I know. Sucks to be a Mac user.

many thanks!!!downgraded 5.1 to 5.0.1 complete novice in this!!

no

jeeze that all sounds hard to do

hi everyone can you help me with my  ipod touch 4g   i bought it from a guy but it isn’t jailbroken and it was updated to ios 5.1 this is how i found it so i jailbreak it  and i put cydia on it but some tweaks don’t work for me i heard that ios 5.1 firmware is the problem so i  went to downgrade it to ios 5.0.1 but the problem is i don’t have 5.0.1 SHSH blobs  i used tinyumbrella to find if any blobs was saved but nothing
  what can i do ?
 tnx in advance

as in i didnt upgrade to iOS 5.1 so i dont have SHSH blobs from previous versions as there was NO previous versions for me… am i screwed completely??

i have upgraded my ipod touch 4g to 5.1 not knowingly that it wont jailbreak untethered, now i want to downgrade it to 5.0.1, i had an untethered jailbreak on 5.0.1, i am following the instruction given above but ifaith is not able to find the firmware of 5.0.1, i have downloaded the firmware twice bt it is not recognizing, i have 1.4.2 ifaith for windows, i want 5.0.1 on my ipod to jailbreak bt it is not downgrading, i dont understand what to do, someone please help……

My iPhone 4 was running 5.0.1 befor I update it to 5.1 without SHSH blob saved. After I jailbreak tethered iOS 5.1, I take a look in cydia I have SHSH: 5.0.1 and 5.1. Is that mean I have SHSH save for 5.0.1? If yes, can I grab it for my 5.0.1 SHSH blob?

if you have jailbroken your iphone 3gs before you can save your SHSH blobs by using tiny umbrella

does it work for iphone 4s too?

i got error 1600..help me

5.0.1 refresh to 5.0.1 by iFaith, and then jailbreaked, but can’t installed cracked apps…

what did you do to jailbreak your 5.1 when i try to jailbreak it i alyaws get A5 error so i couldn’t jailbreak my iphone 3gs or unlock

 Shammer: no, it doesnt.

If I download an earlier version of iTunes, can I just download an earlier iOS version on my 3gs? I seem to remember that iTunes now doesn’t allow that, but earlier versions did. Am I correct in thinking that, because if so I would like to think that I can just downgrade the 3gs to an early iOS version(i.e. 4.2.1) and then do an easier method of jailbreaking and unlocking?

I do not find the signed file IPSW

I just purchased an ipad2 last night and unknowingly, my wonderful boyfriend upgraded the version to 5.1.1 =/buuuuut, i have an i phone with version 4.3.5 is there anyway that i can downgrade the ipad to a lower version if i have a lower version on my iphone???

I just accidentially downloaded the new update for ipod 4g. I had no idea about shsh how to i make it where i can downgrade? could i use my bfs ipod 4g, download that shsh and use it for mine so i am able to downgrade? Thanks

can i use another 3gs shsh files for downgrading

how to do step 4?

i want downgrade iOS 5.1 to iOS 5.0.1
but i don’t have iOS 5.0.1 shah blobs.
is it still possible to downgrade.
