      Good luck.

  1. Is the blacksnow install supposed to be slow? I just clicked it, then a black box that says ‘Post Install Log for sn0w’ appeared with a spinning circle.

    It’s been sitting like that for a few minutes now.

    • I had no issues with my 3gs on blacksn0w but when i did it on the 3g it sat at the post install log and was blank for a ggood 5 minutes i ended up saying screw it.

      • i downloaded blackrain like a few days ago, but anyways. i have a iphone 3gs and it shut down on me, i believe it crashed on me. and know it dosen’t want to turn on anymore? or sync with my Mac..what should i do?

  9. Ive tried running BlackRa1n several times now and still it comes to the first screen lock where it only allows emergency calls. I tried running it with the SIM card (Im T-mobile, phone has never been unlocked) and without it. I actually restored it yesterday thinking that was my problem, but now I cant even use wifi or access my itunes or anything. Its just a paperweight with an annoying message No Sim Card Installed. Insert a valid SIM with no PIN lock to activate phone and iTunes wont recognize it either. This sucks!

  10. I got the same issue – sitting on Post install log for sn0w and beachballing……tempted to hard boot it but dont want to turn it into a paperweight…

    • 1) On your iPhone 3G and 3GS, navigate to Settings –> General –> Reset –> Reset Network Settings.
      2) A dialog will prompt you with “Reset Network Settings” button
      3) Hit this button and turn off your iPhone by holding down power button on the top and then slide to turn off your phone. Now turn on your iPhone by holding down the power button on the top again until you see the Apple logo.

      • I reset the network. It did not ask me to power off but goes into apple logo. Now I cannot power it off at all and it won’t go into recovery mode. It keeps cycling thru the apple logo multiple times evey one minute. I cannot even restore it. Please help.

  21. Hi,

    I installed blackrain RC3 and unlock works fine, only with a reboot the iphone comes in recovery mode. With the iphone connected to itunes and de blackrain jailbreak open the iphone starts up.
    When i disconnect te cable to the PC or MAC, the iphone keeps comming in recovery mode.
    SW 3.1.2 (7D11) Modem 05.11.07.

    Someone has a tip to solve the problem ?
    My workaround is to connect the iphone to PC or MAC whith blackrain jailbrak open. Then the iphone boots without going to recovery mode.
    Even wifi is working.

    Kind regards, Edwin

        • Have you heard any answer yet? I am able to get into recovery mode finally and now restoring. I used RC2 before and did not have this issue. But once I ran RC3 to re-jailbreak, I get into this weird issue again. Resetting the network makes it worse.

  22. Does anybody knows what happen if I unlock my iPhone with this software and I update the firmware with iTunes when Apple release a new one? thanks !!

  23. can any body help? i have jailbroken i phone 3gs 3.1.2, i have installed new docks but it wont let me change it :S ive ticked it in winterboard but it still dosent change… can enybody help me with this? i have downloaded themes, lockscreens, dialers etc with no problems and used them fine.

    Thanks hannnnah 🙂

  24. hey it worked great but i am having problems with my wifi it is not working what can i do to fix this problem i have an 3gs iphone

  25. Will blacksn0w unlock my 3G iphone with firmware version 3.1 (not 3.1.2) on baseband 5.11.07? i updated to 3.1 when it first came out (but never upgraded to 3.1.2) and was able to jailbreak but not unlock, i have cydia so if i add the blacksn0w resource and install, will it unlock properly?

  26. I jailbroke and unlocked fine, but iTunes says “The sim card in this phone does not appear to be supported.”
    What can I do to fix that?

    • I just got a second 3GS today and unlocked it the same way and it works with iTunes. something must have gone wrong with the unlock on the first one..

  27. Which USA carriers will work for an unlocked 3GS? The jail break worked perfectly. Would consider the unlock but which network is the best alternative?

  28. For some reason when I insert the sim it wants me to connect to itunes and it then says there’s a problem with the iphone and to contact apple. I’ve read that the iphone needs to be activated with the original sim or something like that but it was bought second hand and I don’t have the original sim. Any ideas??

  29. OMG thanks sooo much. I have been trying to unlock my phones for AGES. I did both mine and my husbands (3 phones all up) and the only hint I would give is once you download the .exe file use it to jailbreak/unlock one phone then delete the file and download it again for the next phone. I initially tried the same .exe file for the 2nd iphone and it wouldn’t work. Once I deleted the original file and re downloaded it, it worked fine.


    • I jailbroke and unlocked my Iphone 3gs 3.2.1 with 5.11.07………
      MOST of it works. I had to use the “push/wifi” fix to get the wifi back and I have signal MOST of the time……….but after not using the phone for a while, when i either get a call or make a call, the call will “fail”, then the signal goes, then the “searching” appears then the signal comes back strong……..then all the other calls within a reasonable amount of time are fine………if i don’t use the phone for another hour or so, the same thing happens again………

  30. OMG! I am not very experienced at all at this… I actually paid to have my iphone unlocked previously and decided it was time to teach myself… there were a few little things like the blacksnow freeze up which i hit the home button and tried again (per comments from others) and it worked phone is on t-mobile running 3.1.2 with no problems.. I will definitely donate.. All I can say is WOW! If I can do this anyone can.. keep the info coming!

  31. I cant seem to get the unlock to work on this Rogers iphone 3G. When we insert the new SIM card from Bell we get a message asking to connect to itunes and then it says theres a problem with the phone. Am I missing a step? Does the new SIM card have to be IN the phone when I run blacksnow? I also noticed that if I go into the About section of my iphone it says Not available for the carrier. I checked on a Bell iphone and they have Bell 5.1 listed for the carrier. Any help would be appreciated! Thanks!

  32. I unlocked my phone using blacksnow and jailbroke using blackra1n rc3. The jailbreak worked without any issue. After unlocking the phone I put in a tmobile sim card and I have not had 3g coverage or the internet. No safari nothing. Its been nearly two weeks. I have tried the network settings reset. Wifi works fine but anytime I try to connect to internet or facebook it says no data package but I am paying for data package. How can I fix. Please please help me.

  33. Okay i accidentally uninstalled blackra1. Is there any way to get it back on my iTouch without restoring? Thanks. Please help

  34. Ok, I have read here where many have had the same problem after jailbreaking with 3.1.2 firmware on a new iphone, instead of booting it goes to the apple screen for a second then into recovery mode with the itunes and usb cable picture on the screen. Only way to boot is run black rain on the pc while cable is connected to iphone and phone will boot right up. Why? Why will the phone not boot on its own? This doesn’t do any good if you have to repower your phone while away from home. I have seen 10 comments on here, and I would LOVE for someone to address this. I really like having my phone jailbroken, but I have to have it boot up without the assistance of my pc and blackra1n. Please help. thanks. J

    • its the ne iboot thats been installed by apple in ne iphone to help deter people from jailbreaking, there is no fix as yet so every time you turn the phone off or reboot you will have to connect to comp and run blackra1n again!

      sorry but i guess a fix will come in time x

  35. blackra1nrc3 will work for you… just restore your device from itune(shift+restore) and run blackra1n…. if u have wifi&youtube problems… reset network and download push/fix from iphoneil repo… everything should work… thank geohot for the great job…

  36. After much research, the jailbreak on a new 3gs with 3.1.2 is “tethered only” at this time which means that you have to have it hooked up (tethered) to your pc with your usb cable and you must run black rain each and everytime you wish to boot your phone. That sux, but it is a fact right now, no other choice if you want it jailbroken. Word is that development team will have an untethered JB eventually. So I am sticking with the tethered break and hope I can just keep my phone on all the

  37. I downloaded and went to install but when it got to the reboot part. no picture of the guy came up and it was just a blank screen and never ended up restarting.


  38. Hey i have a problem where my service go’s in and then out, fluxuation, then NO SERVICE, then again! and theirs many people with this same problem! but i NEED help, its very anoying! lol.. but either way, i wonder whats wrong.. reseting network setting does not fix it! i need SOMEOTHER thing tp try maybe?? any ideas?

  39. very easy, worked perfectly for my iphone 3g upgrade to 3.1.2 firmware and 5.11.07 baseband. now i can use my iphone with other network. it is very important that you have a working wifi, because after jailbreak with blackra1n, you need to download cydia and blacksnow in you iphone. i had a hard time unlocking mine because of the wifi connection in my area.

  40. i unlocked my phone using blackrain, but now i dont know how to get cydia on my phone. does any body know wat i can do step by step???.. i cant seem to figure it out!!!

  41. I accidentally updated my IPhone with iTunes at version 3.1.2. I bought it second hand and it was already unlocked. After I updated it it worked for 4 days and then all of a sudden I didn’t had signal anymore. I tried to unlock it using blackra1n, downgrade it to 3.1 and then unlock it, update it again and try to unlock it. All in vain. I don’t know what method the previous owner used to unlock it and I am kind of desperate to unlock it, because for the moment it’s just an expensive iPod. Please help…

  42. hi i ave try 5 time and always ave to whait about 5 mins for reboot and after it still not working. what can i do.

  44. i downloaded blackrain like a few days ago, but anyways. i have a iphone 3gs and it shut down on me, i believe it crashed on me. and know it dosen’t want to turn on anymore? or sync with my Mac..what should i do? if i was to take it to the apple store with it been hacked, what would the apple store say????

  45. Just wanted to chime in…. running a 3g previously jailbroken and unlocked on t-mobile(2.2). I froze it and it sat for a while and I decided now was the time to update the phone. I decided that blackra1n was the way to go. It went so smoothly till i couldn’t get the “no sim” error to go away. After lots of hair pulling I figured out that I had to leave in my at&t card in the phone until the very end of my jailbreaking and unlocking then switch sim cards after the final reboot, and now its all good. Thanks to everyone who posted on every site i came to. Without you guys I have no idea where I would be. Goodluck to the rest and most of all thanks to Blackra1n and everyone that had anything to do with it.

  59. I did all the steps, after “make it rain” the iphone automatically reboot. now i have “blackra1n” in the list of applications. i ran “blackra1n” app and selected to install “Cydia” and sn0w packages. After the package install i see pop-up screen saying iphone has been unlocked. I tried different AT&T 3G sim, i see on iphone a different SIM is detected, but only allow to make emergency call, but i can receive incoming call. Has anyone run into the same issue. Please help? thanks in advance for your reply

  63. if you get stuck on the post install log screen with spinning ball for several minutes as i did and many of you have mentioned, just hit the home button and re-run the application again, install snow again from scratch and it does it in like 5 seconds. IT SHOULD NOT STAY ON THAT SCREEN FOR MORE THAN 10 SECONDS!

  64. i ran the blacksnow and everything was working fine all day,all the sudden the phone locks up,I rebooted and now all it will do is keep going into the recovery mode.PLEASE help.The phone wont do anything else.

  67. Hey guys!

    This is weird, because before running blackra1n, I have the “No Signal” screen.
    Please, help!!!!

  68. Hi.
    I restored my iPhone through iTunes and for some reason it got stuck on the “connect to itunes” logo. iTunes wont properly restore the phone since i dont have a “valid simcard without a pincode” in the phone. Blackra doesnt do anything to the phone but just says “running” while the “connect to itunes” logo is still on the phone. I have tried restaring the phone, charging it fully, letting it die and everything else I can think of but nothing works. Do you have any idea of what I can do? I don’t have the simcard that came with the phone.

    Thankful for any help!

  69. if you lose the simcard that came with the phone just go to att store or buy to go att, activate the sim care

    insert ur att sim in ur iphone


  70. i’ve successfully jail breaked and unlocked phone so i could use overseas. now i would like to get rid of it so i can update to 3.1.3 without jailbreaking i tried restore, but said cannot restore invalid. why is that? is it safe to update the carrier settings not the iphone if its jailbroken?



  71. I Have Iphoe 3.1.3 no wifi successfull jailbreak from sn0wbreeze , i dont know how can i unlocked my iphone plz help me 🙁

  72. Tried to jailbreak and unlock iPhone 3GS 32GB with 3.1.2 and 05.11.07 using current blackrain from the mentioned homepage. Program ran through, iPhone went in DFU mode, but afterwards no was there on the iPhone but only a link to a download page, that didnt work in iPhone Safari but required a registration and wanted to download a blackrain app with a couple of hundred megabytes. What is this? Anybody with similar experiences?

  73. Can’t seem to get Blacksn0w to work.

    Restored original iPhone 3G to 3.1.2 (7D11) firmware version, and baseband 05.11.07. iTunes version 9.1 (79), current version. Blackra1n used to jailbreak; that worked fine.

    Tried installing Cyadia and snow. Cydia installed, but snow got stuck on the “Post Install page”. Re-ran Blackra1n on the iphone and installed snow again … it appeared to work, and I got the full Post Install page.

    Unfortunately, it doesn’t appear to be unlocked. iPhone works fine on Rogers (my native carrier), but I get “No Service” on a Telus Sim card. Both carriers support GSM networks in this area.

    Any suggestions, anyone? I’ve run the full install process twice (with iTunes restores in between), but the end result is identical.

    Thanks in advance…

  74. I have problem that I can’t access the internet or any application that using data. I have T-mobile with data plan. The iPhone keep telling me that I don’t have data access plan. I can call out and receive calls but no accessing the internet. Help please?


  75. Raju, one thing is not clear that why Blacksnow is required ? I already unlocked my 3GS with Blackra1n, after that it starts working with Airtel but it is not connecting to sites on Internet. Also after restarting my phone, always need to run BlackRa1n…Can you give some suggestions regarding this whole matter..Thanks in advance for your help

  76. I have already unlocked and jailbroken my iphone 3G 3.1.2 with blackra1n and snow when it first came out. I do have slight issues with my wifi and push notifications. if i upgrade to blackra1n RC2 Final will that wipe my phone of all my apps and info etc? or will it keep all that info?

    • uhhh i have the same ordeal/problem i keep jailbreakng the iPhone with blackrain but i ended up to the same iTunes logo this is so frustrating!!!!!!!!!!!!!!!!!

  77. I’m very impressed! I didn’t have any problems with these directions and I am not very techy. Really appreciate the ‘easy to follow’ step by step directions. I moved to Germany recently and have been thinking about unlocking my iPhone 3G and now I finally did it and it only took minutes, if that! THANK YOU!!!!

  78. hi, i hv some problems here. my iphone is 3GS 3.1.2. i accidentally uninstalled blackrain application on my iphone. then, my iphone screen shows itunes logo and the “connect to itunes” logo. i’ve tried to jailbreak it again with blackrain, but it can’t be done. after the jailbreak picture shows on the screen, it goes back to the itunes logo again.
