Hey, I had the same problem ( error 21)
But i solved got out of the restore mode by
download a ispw 4.0.1 (official) and restore it.
In the beginning of the process it will have an error,

Hey Guys,
This Is For People That Encounter Error 1600 While Restoring To Custom 4.1 Firmware! YOu Need To Place Your Device Into DFU Mode Then Shift/Option + Restore and select the custom firmware!

Thank YOu And GOod Luck

Niks October 26, 2010, 9:35 am

GUYS DON’T WASTE YOUR TIME. YOU HAVE TO RESTORE THIS CUSTOM FIRMWARE (WHICH IS COOKED IN MAC) ONLY FROM MAC NOTEBOOK. CUSTOM COOKED FIRMWARE FROM MAC WILL GIVE YOU ERROR NO. 1600 AND 21 IF YOU TRY TO RESTORE FROM WINDOWS. I HAVE TRIED THIS ON 3 IPHONE 3GS AND FINALLY GOT SUCCESSFUL FROM MAC.

54TRains December 6, 2010, 3:03 am

That’s what ireb is for…

james95121 October 23, 2010, 9:28 am

I think the 1600 is normal just use tinyumbrella to kick out of restore mode

Whish October 23, 2010, 9:50 am

it doesnt occur after installing or anything
it said checking the iphone then bump error 1600

sam October 23, 2010, 9:58 am

i get error 21 when trying to restore to custom firmware. I think i did something wrong in step 2. Does anyone know how to do right in step 2?

Warraich October 23, 2010, 10:47 am

I am also having errors as Whish. When i put the iphone in DFU mode and try restoring it gives me error 1600 and when i try with the iphone on it gives me error 21.

Warraich October 23, 2010, 10:51 am

Oh and error 21 when i try with the iphone in recovery mode. Has this worked for anyone at all?

rahulbelekar October 23, 2010, 2:39 pm

does not work with iphone 3GS firmware 4.0.1 gives error 21 …

Don Bilbo October 23, 2010, 3:40 pm

same problem here with my iPhone 4 (current iOS 4.0.2)
I tried to install this custom firmware but I keep getting Error 21

indi October 29, 2010, 9:31 pm

Don’t try with custom FW, search for update iOS 4.1 without upgrading baseband, be careful to keep your current baseband as is if you need an unlock, I successfully did it

Join ipsw October 30, 2010, 12:08 am

Indi,

what did you use? tiny umbrella for iPhone 4?

Is there any method you know of for 3gs?

Thank You

indi November 17, 2010, 1:42 pm

For iPhone 4: use tinyumbrella to restore ORGINIAL firmware, then JB with ra1n or pois0n; do this CAREFULLY to keep your baseband for unlock

For 3GS: drop me email ([email protected]), there would be a guide for you

freed October 23, 2010, 3:51 pm

It doesn’t work. I have error 1600 …..
Any ideas ???
HELP Please 🙂

Godfred October 23, 2010, 4:12 pm

Iphoneheat could you please test these custom firmwares if it really works as it has not worked for a single person.
i want to use it but dont want to go through that hell of getting the iphone stucked,i dont have an alternative phone to use if this happens
thanks

HermannTheGerman October 23, 2010, 4:16 pm

Hi Error-Guys,

have u ever tried to run iREB 4.0.x-4.1 to prevent the fuckin errors before installing the CFW via itunes?
iREB keeps away the 1600-1609 and 21 Error messages. So you are able to install the CFW successful without any errors.
Here you can fina a How TO for IREB:
http://jaxov.com/2010/10/how-to-use-ireb-4-0-x-4-1-bypass-16xx-1015-21-error/

Thumps up!

freed October 23, 2010, 6:21 pm

do iReb support 3gs ???????????!!!!!!!!!!!!!!!!!

Avi Alkalay October 26, 2010, 2:06 pm

Current iREB only supports iPhone 2G, iPhone 3G, and iPod Touch 1G/2G [MB]

Zaffar October 23, 2010, 6:02 pm

I got the same errors 1600,21.while restoring my 3gs to 4.1 through custom firmware.if anyone get the solution. Plz post and help. Appreciated.

srky October 23, 2010, 6:02 pm

Few persones pointed on dev-team webiste in comments that for first time you should restore on mac, because pwnage tool runs exploit on iphone when it is in dfu mode….. after you pwn it on mac every next time shouldn’t be problem on re-pwning it on windows

source: comments on dev-team web site

Avi Alkalay October 26, 2010, 1:47 pm

This is the only comment that makes sence here.

PwngeTool does several things:
1. Creates a custom firmware file which is not specific to your device but is specific to some settings and a profile (e.g. locked vs unlocked)
2. Puts your device in a state that is ready for iTunes to install that custom FW. This is where jailbreak happens.

My advice to non-Mac users is to stay away from from these IPSWs, do a normal non-jailbroken firmware upgrade and jailbreak it latter with limera1n or greenpois0n.

If you need unofficial unlock from ultrasn0w, your only option seems to use a friends Mac with PwnageTool.

The iReb link someone posted here seems interesting but didn’t checked yet.

Oh and YES, iphoneheat.com is quite irresponsible publishing this without more testing. They could at least reply to some questions, verify iReb or unpublish this guide.

I have a spare iPhone 4 which I intend to do some testings today and will keep you posted.

Kc October 23, 2010, 6:40 pm

iPhone 3G Custom iOS 4.1 Firmware IPSW
Activated (for UnOfficial Carrier Users)
Does not work as well, does not want to restore. I am downloading the not activated to see if that will work.

mazeeff October 23, 2010, 9:09 pm

Folks. Don’t be dumb. You can not jailbreak/update, by just restoring a file. Why do you think that folks go to the trouble of writing jailbreak software. The file that these programs produce are unique to each Iphone.

Anomux2 October 23, 2010, 9:49 pm

No news 🙁

Try doing the custom firmware with PwnageTools 4.1.2 Please

skynet October 25, 2010, 6:43 am

what is baseband version of the custome firmware?

ss October 26, 2010, 1:25 pm

Not working, lame post, a gat the error 21 and 1600

🙁 wait for sn0wbreeze it will jailbraik and unlock 🙂

yun October 27, 2010, 2:00 pm

3gs, old bootrom, [before / after] JB on [4.00 or 4.01]
This Custom F/W not working too with error no 21 or 1600 or 1604

i’ll try again after install sprit2pwn,
but now ‘repo.woowiz.net’ site under mainternance while in 3 days.

Anyway, seems better waiting for updated Ultrasn0w.

jax October 27, 2010, 11:46 pm

Guys, as far as i know, to install these firmwares YOU NEED TO BE RUNNING THE PWNAGE TOOLS!!! so obviously it wont work on windows because the program isnt running…

So dont waste your time downloading, IT WONT WORK unless you are using a MAC and running PWNAGE TOOLS…

its something about the limera1n on the program.

Re: iphone 3gs wont restore error 21
Posted: Jun 25, 2010 4:42 PM   in response to: itslindsay  
  Reply Email

Got a solution, on Windows Vista with 3GS phone.

I created a new user in the control panel, restarted, then logged in as the new user.

I then opened iTunes, which installs for the new user and then connected the phone. It then went through the OS software update no problems.

I stopped it at registering/setting up and switched back to my original user profile and it automatically restored from the back up.

Hope this helps – amazing how lost you feel when your phone packs in :-/

  iPhone OS 3.1.2    

Pacman77 October 29, 2010, 3:30 am

Hi Guys,

The custom firmware as Jax said, will only work installed through a Mac, i tried installing through Vmware(With mac emulation) but the Pwnage tool freezes when putiing the iphone in DFU mode.
The tool also “prepares” itunes to bypass the verification with Apple that’s why you’re getting the 1600 and 21 errors in itunes.
you have 2 options:

1 – wait for the relase of the tool in windows

2 – the solution that worked for me, ask a friend of yours who was a Mac to do this in his computer

yesterday, i made the jailbreak on Ipod Touch 3g, and iphone 3GS all went quite well.

The only problem that i have is that the ibluenova app does not work with IOS4.XX

hope i helped,
Pacman77

rajhere October 29, 2010, 10:46 am

Hey guys

Which baseband on custom firmare??

Please help me.

indi October 29, 2010, 9:38 pm

nobody care since you asked a “so complicated” question!

restoring with a custom firmare will keep your baseband as is, but it seems not to work for non-mac users

iPhoneHeat, do you have any res.???

Join ipsw October 29, 2010, 11:03 am

Is everybody joining the files with Hjsplit
so should I even try to do or not I have no access to mac

ipht3chone October 30, 2010, 3:34 am

For all those using windows & trying to install custom firmwares. check this link 1st. very important stuff that might shed some light on things.

http://wikee.iphwn.org/howto:pwnagetooltweaks

A little resarch goes a long way.

Dheeraaj October 30, 2010, 9:10 pm

hey guys My advice is to use limera1n it also work’s with new bootrom, I jailbreak my iPhone 3g 4.0.2 and 4.1 (new bootrom) with this software, it works well and none of the features are blocked, it will also save your time. After jailbreak you can install cydia and unlock with ultrasn0w.

mibaksh November 5, 2010, 3:27 am

hey guys just an update… you can use the latest redsn0w 0.96b2 to put the device into the “Special DFU” and THEN use these custom ipsw’s.

I just did it on a 3G it works… I got error 1600 and 21 before without the the redsn0w so i can tell u i am relieved!

get the latest redsn0w off the devteam blog/here:
http://xs1.iphwn.org/rs/redsn0w_win_0.9.6b2.zip

good luck all

mibaksh November 5, 2010, 3:27 am

ohh and thanks for the RS links! much love

Dmitriy November 7, 2010, 12:14 am

How did you do it with redsn0w? I don’t understand? Did you use custom firmware?

Dmitriy November 7, 2010, 11:21 am

Don’t work on my 3gs

Dmitriy November 7, 2010, 3:33 pm

It works. I had a error at first attempt (something about 0x000…), but at the second attempt everything was uploaded

brick__top August 30, 2011, 7:37 am

This is it guys! Use redsnow 0.9.6rc8 and only put device into custom pwned DFU mode. Then use itunes to install custom firmware.
Thank you!!

AfRoO November 6, 2010, 2:50 pm

hey,
I have tried it but 🙁 it says you can’t restore your iDevice with unknown IPSW. so what can I do????
my device is
iPhone 3Gs
Firmware.iOS4.0(8A923)
BB: 05.13.04
I Jailbroke it using jailbreakme & unlocked it by Ultrasn0w & I’m already saved my SHSH Blobs.

so ummm any idea??

Dheeraaj November 6, 2010, 4:01 pm

you have to use 4.0.2 or 4.1 IOS, with jailbreakme even after u did unlock with ultrasn0w and if it says no service then you should wait for couple of hrs it will get the carrier automatically it happened with me once, while jailbreaking with redsn0w browse to 4.0 ipsw instead of 4.0.2 even though your iphone have original 4.0.2 version.

AfRoO November 8, 2010, 1:57 pm

it wont I tired many time, when I use the custom thing it showing me error 1600 and when i use the official firmware it stick on load mode, so so

Info November 7, 2010, 2:26 am

I can comfirm this does work using iphone 3g. I used a custom firmware from a different webpage, however, I may have download a non hactivated version. I got the pineapple logo but i was stuck in activation. I treid to restore it again using the firmware on this site but I got the 1603 error in both DFU and Restore mode. I then tried to use Redsn0w to attempt to flash to 4.01 but even tho it flashed, the phone did not work. In a last ditch effort,I used redsn0w again to bring the phone in DFU mode and then use itunes 10 to do a restore using the firmware on this site… my 3g is now on 4.1, baseband 5.13… In the end, it works, but maybe wait until something is easier out… There are many ways to mess up.

AfRoO November 8, 2010, 1:52 pm

hey,
My iPhone is fucked up yep it does I have iPhone 3GS-hit iOS4.0 UNLOCKED BY ULTRASN0W, it was good but this custom thing fucked it up my iPhone stuck on recovery mode and when i tried to restore it with official firmware it kept sticking on loading mode with apple icon IDK what to do, help me???????

Dheeraaj November 8, 2010, 2:55 pm

use umbrella-4.1.4 to kick your mobile out of recovery and backup your ECID with cydia, then restart your Iphone while it is connected to computer use limera1n to put ur phone in recovery mode as soon as your iphone goes into recovery mode close limera1n immediately ( or you can also try limera1n to jailbreak) then download fresh original 4.0.2 ipsw file and restore it with itunes 10 if itunes gives you error 3194 then go to c:/windows/system32/drivers/etc and open hosts file in notepad and at the end of this file add 74.208.10.249 gs.apple.com if this is already existing then just insert some more space between ip add (71.208.10.249) and gs.apple.com and save this file. itunes will now restore your phone to 4.0.2 without any error. be care full with custom firmware you may loose your unlock with ultrasn0w do not use any tool that was/is meant for mac systems/software’s, most of the custom firmware are built on mac with pwnage tool. better jailbreak it with redsn0w or limera1n on windows OS.

AfRoO November 8, 2010, 7:42 pm

hey thanx for ur reply,
i tried to kick out the recovery mode using umbrella-4.1.4 but it only restaring the iPhone then it come back to the Recovery mode, like before

AfRoO November 8, 2010, 7:47 pm

sorry but I want to explain what is my problem, my problem is my iPhone 3GS keep sticking on the middle of the LOADING mode when i restore it with official firmware, I been waiting for may an hour but it wont done, IDK what todo.

asweproceed November 8, 2010, 6:37 pm

hi i got 3gs from bell now is jailbroken with limera1n work fine but not able to unlock unofficial carrier to put telus sims card .ultrasn0w not supported by cydia a this moment.i know the updated version should fix the problem.but does anybody know of a software that is able to unlock iphone 3gs right now.and also my 3g is not able to be jailbroken i tried 30 times and i`m stuck with this shit because my 3gs is jailbroken but not unlock !!!!this pisses me off big time….ty and hope to find some wiz kid that can fix my problem ..have a nice day.

tuna November 9, 2010, 7:30 pm

To put these custom IPSW’s on a 3gs, you have to use redsn0w first. (the latest version has an option to put the phone in a custom firmware friendly dfu mode that allows itunes to flash any custom firmware). Then, you can shift-restore the file with itunes. Do you want an easier solution? use a Mac…

tristan November 14, 2010, 1:27 am

has anyone successfully restored to 4.1 using these custom firmwares?

limys November 16, 2010, 7:21 pm

surencal November 21, 2010, 10:52 am

Use “iREB-4.0.x-4.1-RC2” to go into DFU mode and it should work. I will give it a try and let u all know.

Blade December 29, 2010, 4:07 pm

Hi everyone,

i need some help, i jailbreaked my iphone 4 with limera1n, however, after instaliing cydia i couldn’t install most of the app’s, therefore tried to do the “Install Complete Essentails” and the problem continued. After that i thought it would be better to jailbreak it again, so i restored my iphone but as the 4.2 firmware was released, now i have that firmware installed.
I going to downgrade it to 4.1, but the problem is that i’ve been reading a lot about SHSH blobs, and i couldn’t understand one thing, if i have firmware 4.2 installed and save SHS blobs, can i downgrade it after? Will i use this SHSH Blob for anything after downgrading my iphone?
Thanks in advance for any help

iVP January 2, 2011, 4:41 am

Hey, i finally have my iphone back! 3GS 16GB

Saved SHSH blobs 4.1
IOS 4.1 firmware (original from iphoneheat) not custom.
itunes 10.0.0.68
Tiny Umbrella 4.1.5, (ran TSS Server before starting precedure) didn’t work the first time without TU.
I also modified the Hosts File on
(C:\windows\system32\drivers\etc)
Added Strings : 74.208.10.249 gs.apple.com

Still had problems despite my prior posts. But saved the day when i went back to my original version 4.1. Ipone came up with everything that it should (not jailbroken). I will now look to upgrading it to 4.3.3 before i proceed any further. The problem is itune wants me to go to 4.3.5 and i know thats a no-no as it cant be jailbroken yet

I would like to take the chance of thanking you for the professional direction I have usually enjoyed checking out your site. We’re looking forward to the actual commencement of my university research and the overall preparation would never have been complete without browsing this site. If I can be of any help to others, I would be happy to help by what I have learned from here.
