Sep - October 24, 2011 at 9:05pm
When i download the iPhone2,1_3.1.2_7D11_Restore it's not a ispw file is a zip file.
Rachel - January 7, 2011 at 11:58pm
I can't get past step five. it says" Unable to recognize ISPW " what does this mean? and how do i fix it?
Awn - January 8, 2011 at 1:57pm
rachel, why not try ver 4.0? much faster and easier on the battery.

Is it true that if I currently have OS 3.0.1, I won't be able to upgrade to 3.1.2? I tried to JB and kept getting the 3194 error when I tried to restore to 3.1.2. What's the way to upgrade??? Do I have to wait until someone come up with JB 4.1 in order to upgrade my OS? Please advice. Thank you so much.
Awn - September 12, 2010 at 12:58pm
if you have never jailbroken, then now is NOT the time to jailbreak, you have to wait till 4.1 is jailbreakable.
AY - September 28, 2010 at 5:18pm
Hello Awn, My 3Gs is jailbroken and unlocked running 3.0.1. I still should wait for 4.1?

I'm following all the teps to jailbrake my 3gs 3.1.2 but when it comes to dowload iphone2,1_3.1.2_7D11_Restore.ipsw it actually dowload a Zip file. Someone can help me and tell me why?
Awn - July 25, 2010 at 1:39pm
try downloading with mozilla
Chigger - July 19, 2010 at 10:37pm
Quick question, i am currently running a jailbroken 3gs with 3.0.1. I want to update to 3.1.2 but not 4.0.1/ I tried to do the shift click restore method, but it wouldnt take. probably because i never had this firmware installed in the first place. is there any way to install a specific firmware, without updating to the curent one and backtracking? thanks
Awn - July 25, 2010 at 1:41pm
if you have not backed up signatures for your phone, i highly doubt you could upgrade to 3.1.2/

Dear Team, i have been observing all the post in regards with jailbreak iphone 3GS but it seems that thre is something still to be explained or provide a little bit guideness as i know those who have 3GS (old botroom) are experiment some issue at the time to restore the IPSW created by the seems that apple constantly refuse to update with the firmware...i am been trying to do everything according with your guideness but i can not get through to unlock or jailbreak my iphone 3GS (old botroom) I would like to ask a simple question; why it is that when you finish to create the IPSW with Redsn0w or Pwgnage tool this IPSW when you are using Itunes does not upgrade that IPSW, why is keep giving an error message? your response to his inquiry will be highly appreciated.
Andy - June 17, 2010 at 2:50am
Ok this is frustrating....I followed step by step based on this tutorials. After I restore the firmware 3.1.2 and install the redsnow all I see is the completely black out screen nothing comes up and I cant power on/off ...NOTHING. But when I connect to the Itune it says im in the recovery mode but you cant really see it because the screen is black. Anyway, I have 3GS 16gb and if anyone experience the same please share. Thanks in advance.
unix - June 28, 2010 at 3:26am
The same problem , any help ?
Awn - June 30, 2010 at 12:30am
i have not experienced it, however; i could think of the following: 1) try the procedure on a different pc, with a freshly downloaded FW and redsnow, 2) try restoring 3.1.2 then balckrain it, just to see what happens 3) if all fails and you have an OLD bootrom, try OS4
///AMG - June 16, 2010 at 1:40pm
I read the link that someone metioned below but i dont understand this did you add this anyway ? " So, open the file C:\Windows\System32\drivers\etc\hosts (Windows) or /etc/hosts (Mac OS X) and add the following entry to the bottom of the file. "

i just have a question, i have two iphone 3gs, both 3.1.2 / 05.11.07 / 51week, one i didn't touch at all, fresh from at&t, locked and not in use, the other one i did redsnow several months back, so now its tethered jailbroken and unlocked. is the perfect jailbreak out yet? do i need to treat these two phones with two different methods if i want to unlock and jaibreak them perfectly? if yes what should i use? its been bothering me for months, since the untouched phone was a birthday present for my dad but i still haven't give him yet cause he doesn't know how to tethered boot it, any help?

if you have new bootrom, do 3.1.3, or wait till 4 is jailbroken for your phone, otherwise, upgrade to 4 reading the guide.

Hi All, I have just bought factory unlocked Iphone 3GS (3.1.3), and I am totally unfamiliar on how to install applications etc on my phone. I would request experts for step by step instructions on how to install applications on my factory unlocked Iphone 3GS. Thanks and regards, Anees

Hi, I have tried jailbreaking my iPhone using redsn0w but I keep going back to recovery mode (the USB + iTunes logo) after reboot. Even if I just tick the "'just tether to reboot'" it still doing the same thing... Any idea how to fix this? Any help will be greatly appreciated. Thanks
me - April 17, 2010 at 2:46pm
Hey, noob question, do you jailbreak with or without SIM card in your iPhone? Thanks!
Awn - April 18, 2010 at 1:47am
doesnt really make a difference
kelvin - April 2, 2010 at 9:50am

My old iphone just crashed and got a replacement one. was relieved to see 3.1.2 7D11 and the correct 5.11.07 base band. I have tried Blackra1n and redsn0w several times but i can't get it to Jailbreak Redsn0w: hangs at uploading exploit and that's it Blackra1n: seems to go through fine, but the blackra1n icon never appears! the interesting thing is that my old restore file kept the #% for wi fi and battery.. should I try a fresh ipsw file and see if that works? but then I have to rebuild everything from scratch! Thanks for the help!
luvrama - March 9, 2010 at 9:53pm
I also could not install the .ipsw file as Apple server denied the restore. I read the saurik post and modified the host file, included the following entry, but still I'm not able to restore the ipsw file. any help would be greatly appreciated.
Awn - March 10, 2010 at 6:17am
did you ever read this message when you turned Cydia on, "This device has SHSHs on file for iPhone OS 3.1.2"? if you did, then you have a problem following the tutorial, if you are certain that you have never seen such thing on Cydia's homepage, then, you have to follow this link; awn
///AMG - June 16, 2010 at 1:44pm
How did you modify the host file ? Thanks.
venkat - March 6, 2010 at 7:33am
Hi, I followed the exact steps and the firmware is installed and jail broken. But my Carrier is not listed in the Network settings. I upgraded from 3.0 to 3.1.2 using redsn0w. Could you please some one help me. Urgent
Awn - March 6, 2010 at 1:22pm
did you unlock?
Ravi Dawar
Ravi Dawar - February 25, 2010 at 2:47am
I was able to jailbreak into my iPhone after several tries. It also got unlocked but i am not able to connect to my belkin wireless router, it says 'unable to join network' even after i supply the correct password. I am using WPA aecurity. After that, i tried with WEP(using index key 1 passkey) but that did not work either. When i switch off the security on my router it gets connected. Can some one tell me what security and encryption technique should i use with my iPhone?

Qaisar Salim - March 6, 2010 at 1:52pm
Reset ur network settings
mrkhamsani - April 16, 2010 at 5:14pm
usually,resetting the network setting on the iphone will do.
hardcore - February 24, 2010 at 5:00pm
Does anyone know if there will ever be a crack for the fixed bootrom on the newer models?
HO - February 24, 2010 at 1:32am
So I decided to do a new Jb using 3.1.2.....IT DOESN'T WORK!!!!, when the ipsw is checked with the fkn Apple servers it gets denied, so this tutorial is useless unless there is a workaround or may be that the ipsw is not the rt one?
Awn - February 24, 2010 at 1:36am
try reading this
HO - February 24, 2010 at 2:08am
Thx I forgot that and also that I just installed my full ver of Win7, so it means that there is a small mistake on the tutorial and they skipped the step about the Host file. Thanks again! :) My only issue now is my baseband is 05.11.07.....unlock.......
Awn - February 24, 2010 at 2:41am
try black snow
HO - March 1, 2010 at 9:08am
I tried doing my second phone, it has the newer bootrom, for that I will need to run redsnow everytime i restart the or turn off the phone rt?, btw, I still don't get the way it works after 2 tries i gave up, supposedly the phone got jb but when it reeboted i got back to the "connect to itunes screen", so now it's running 3.1.3.....I hate Mapple.....
Awn - March 1, 2010 at 9:52am
unless you updated it to 3.1.3, do not assume that you are running it on your iphone. try running redsnow again to boot your iphone, if that did not work; restore to 3.1.2 (using the method in then run blackrain, AND REMEMBER, DONT upgrade to 3.1.3.
fey - March 7, 2010 at 12:51pm
I also could not install the .ipsw file as Apple server denied the restore. I read the saurik post but what are the exact steps to modify the host file in system32?
HO - March 8, 2010 at 2:15am
It depends on what OS ur using, Xp is just look for the file and "shift+rt click", then select "open with", use Wordpad, after finished click "save" so the name and type stays the same. On vista or Win7 u have to open Wordpad as and "administrator", so look for the program on ur start menu, instead of left click to open use "rt click" and select "Run as Admin..", after finishing the mod just select "save".
HO - April 29, 2010 at 12:28am
...tried unlocking with Blacksn0w and now phone is frozen, won't go beyond the ugly Apple logo.....3.1.2 already Jb... :(
Ceav - February 21, 2010 at 12:58am
Got a failed message, it says that Apple won't validate the restore !!!! Any ideas ??. Recently update the firmware 3.1.2 through itunes, does it has anything to do with the error??
kasper007 - February 14, 2010 at 7:17am
i have windows 7 x64 and i tried many times to jb my iphone but nothing.. I've done all the steps but in the end when says rebooting it never opened... please help..
Eren - March 28, 2010 at 9:12pm
This happened to me to and i have windows 7 x 64 ... exact same thing happened help please :(
Awn - March 29, 2010 at 2:15am
Try keeping a flash disk plugged into a USB port while you are restoring the firmware and jb, and tell me what happens!!!!!
ptl - February 12, 2010 at 9:54am
hi, i have jailbroke my 3gs but no carrier, anyone help please
x - February 15, 2010 at 11:48pm
if you have wifi - install ultrasn0w from cydia
Adrian - February 9, 2010 at 9:10pm
I have an already jailbroken and unlocked iphone 3gs my question is if i still need to the whole step with itunes or can i just load the .ispw with redsnow, do I have to restore the iphone with itunes? because i tried to do that and itunes says that my devide is not eligible for update thanks
Adolfo - February 6, 2010 at 8:09pm
itunes says my device is not eligible for update after i choose new ipsw.Help
x - February 7, 2010 at 9:18am
I'm hoping that cydia will save us by hosting the shsh file - my request is still pending, so i don't know if it will verify the 3.12 firmware as apple will not (only 3.13 right now)
coolpilot - March 30, 2010 at 2:58am
this thing doesnt work for the 3gs on 3.1.2 or 3.1.3 either... i have a older 3gs- week 05. iinitially it was on 3.1.2 i tried jailbreaking as mentioned above and the process ran smoothly until it had to reboot at the end. well it did not reboot and remained stuck in the recovery mode. I then did a restore to 3.1.3, didnt have any other option. And again tried jailbreaking with the method described above. Now redsnow says jailbreaking done, rest of the process to be completed on the iphone. But nothing actually happens on the phone. Then i normally tried switching it on again and it came to life but not jailbroken. I am still on 3.1.3 without a jailbreak.... SO THIS METHOD DOESNT WORK.... PEOPLE WHO HAVE 3GS 3.1.2 BE AWAY FROM IT OTHERWISE YOU WILL HAVE TO RESTORE TO 3.1.3 IN THE END.... BEWARE GUYS!!!
termal - February 5, 2010 at 4:43pm
itunes says my device is not eligible for update after i choose new ipsw. (my iphone is on 3.0 and jailbroken& unlocked) so i'm stuck at step two. any ideas?
x - February 7, 2010 at 9:17am

z04 - February 3, 2010 at 5:13pm
The iPhone2,1_3.1.2_7D11_Restore.ipsw doesn't exist in the zip file downloaded from the link shown above in this tutorial. Is there somewhere else we can obtain it since it looks like there's a new firmware (3.1.3) now?
Carlos - February 21, 2010 at 12:50am
If you are using Explorer it won't work, try dowloading the file through firefox.
RespondBack - February 2, 2010 at 3:13pm
This seems awfully complicated! Isn't BlackRa1n easier if you don't need custom logos???
Dave - February 2, 2010 at 1:54pm
I have week 49 of iphone 3gs, i selected yes for when it ask me if its older than 41 week. Redsnow began jailbreaking, but after its done and it reboots Im still stuck at the plug cable into itunes. Did i do something wrong.
Fernand - February 3, 2010 at 2:57am
Same problem! but I do not have a simcard in the phone so I just figured that was the problem.
Stanci-E$ite - February 3, 2010 at 3:24am
I have the same problem !!! After using this JB I still have to after rebooting the device plug it to computer and run redsn0w or blackra1n again :((( Any idea ??? I did all the steps correctly ! Many times :(
kkkkcccc - April 17, 2010 at 12:42am
same probleM!!! how solve?
Derek - February 2, 2010 at 12:00pm
Hey, which means everytime i reboot, i will need to run redsnow? and anything special about this jailbreak?
mes2005sd - February 2, 2010 at 1:20pm
I you follow the instruction and read all the information it will tell you that if your Iphone manufactured in week of 40 or 45 it will have fixed bootrom and you will need to plug your device into computer and using either blackrain or redsnow every time you turn off and turn on your device... please re-read carefully the instruction.. another word for it tether jailbreak
jason - February 2, 2010 at 10:47am
Everything went on smoothly until the final part where the installing take part on the phone itself... it shut down automatically but never reboot. waited for almost 20 mins but it still never boot up... restored and jb again for 4 times.. still having the same problem..
termal - February 9, 2010 at 1:30pm
same here : (
termal - February 10, 2010 at 4:35am
i figured it out. i was checking "already pwned" option on redsnow (beacuse it was) and i was getting a bright black light on iphone but nothing else after step eleven. then i tried to do it without checking "already pwned" and it worked. other than that blackra1n unlock brings issues about wifi and gps. but there's solutions on the net.
Darren - April 2, 2010 at 3:06am
i also have this problem. but for my case i do not have the option of unchecking already pawned. please help!
wee - February 2, 2010 at 7:49am
oohmygod You just run redsn0w again but now tick 'jsut tether to reboot' (not install Cydia) iphone will autamatically reboot properly
backstep - February 2, 2010 at 9:37am
That we know, but after shutdown or reboot, u still need to use redsn0w or blackra1n.
MiMi - February 11, 2010 at 11:57pm
after shutdown/boot, how come i cant find the cydia icon? it says DONE...
MiMi - February 12, 2010 at 12:00am
and i tried both 'just tether to reboot' and 'install cydia' i still cant find the cydia icon after the screen is back on, it seems like nothing had wat does that mean? so where can i find cydia on my phone?
oohmygod - February 1, 2010 at 11:20pm
After i finished step 11, my iphone screen just show a pic of cable connecting to itunes and it just freeze there.
wong - February 2, 2010 at 12:43am
you did something incorrectly that why it hung you there. I have done 4 3GS just about 30 mins and all of it work perfect....
Chheng - February 3, 2010 at 1:40am
Hi Wong! just to confirmed with u that after JB with above instruction than after restart or reboot ur 3GS iphone there is not locked anymore (no need to run Blackra1n) to go normal mode. Thanks for your reply. Chheng
