2.0 and 2.0.1 Troubleshooting

BigBoss BigBoss has written a nice article that gives a lot of 2.0/2.0.1 troubleshooting hints and tips. Below is a snippet of the article.

Many comments on various issues in 2.0 or 2.0.1 upgrades. Many questions have been answered numerous times. I am adding a summary of a lot of the problems and solutions in this post for reference. I can also update it over time if we need it.

Problem: Mail App crashes after my update.
Solution: This is caused by the sync of the backup from iTunes. The permissions on the mail folder are incorrect (it’s owned by root). The easiest fix is to run bossprefs, click more, and click “fix user dir permissions”. You may need to reboot.

Problem: I have AT&T or a contract carrier. I jailbroke with your guide and now I have no service.
Solution: You activated and you shouldn’t have. iTunes will activate for you but because you clicked the activate button, iTunes did not get to activate. Now your account is not validated. You need to redo the steps and not check activation on your image.

Problem: I have an unlocked 2g phone. I updated to 2.0. Now I get incorrect SIM.
Solution: You did not activate and unlock. Redo the steps and make sure you activate and unlock. In winpwn, this is “activate” and configure boot neuter on the last tab. (See my guide). On osx, this is saying “I am not legit” when asked in pwnage.

Problem: Winpwn IPSW will not complete. It just errors out.
Solution: This one is caused because the size of the image is larger than the partition space. Generally resizing the partition to 550mb solves it.

  1. Thx guys!

  2. I’m still on 1.1.4 but am updating to 2.0.1 today. Can I create the custom 2.0.1 firmware and just restore to it from my jailbroken 1.1.4 phone?

    • Simply you can only restore to a custom ipsw “just like that” if your iphone is pwned already. Otherwise use pwnagetool or winpwn (follow their instructions or read one of the several pwn guides on the net) to restore your device using the dfu exploit (to pwn it ;-)).

  3. aye.. that first one covers the problems I had. I ended up moving back to 1.1.4.. I’ll probably stick here until 2.x.x gets video…

    Mail crashing after upgrade to 2.0 on non-jail broke iPhone:
    I have been jail breaking since the beginning so I am in now way against it, but wanted to mention a solution for those who are not jail broken. I had a few jail break hiccups on the new 2.0 firmware so I decided to go un-jailbroken for a while which lead me to search for a different fix. I found these instrution on the apple discussion boards and it worked great for me.
    1) Restore your iPhone to the latest 2.0(.1) firmware. Use either the local copy on your hard drive or press Option key (Mac) or Shift key (Windows).
    2) Let the iPhone to a clean install of the firmware.
    3) When you are prompted to restore your BACKUP (not firmware) WAIT. (The original instructions said to disconnect iPhone but I was worried it would exit the restore process in iTunes so I left mine plugged in and just followed the next step)
    4) Go into Settings -> Mail and create any email account (Yahoo, GMail, etc.) and verify the connection.
    5) Open the mail application to ensure it is loading properly.
    6) Connect the iPhone back to your computer (only if you disconnected it)
    7) Select the backup that has the data you wish to restore.

    Upon restore of the backup, your mail application will be working again.

    everytime i sync all my app store app to phone soon after if i use cydia or installer phone crashes requireing a restore done 12 restores now a bit sick og it all i woould rather use my app store apps than installer and cydia because they always crashing is anyone going to sort it out come on dev team

  6. Too late for me. I had to sync an old calender to my phone…
    I had stopped rstoring…but i was bummed that my mail was crashing..

  7. Yea, I had the e-mail problem as well. I just went straight into BossPrefs and it worked.

  8. thx for this doug…..although im having problems that it seems NO one else is having. After HOURS of searching i found that i forgot to install the bootloaders 3.9 and 4.6 when pwning……so ever since the performance has been AWFUL……anyway im restoring now…..thx again!

  9. I have had to restore to a custom 2.0 firmware twice now. The first time the phone crashed I was respringing after editing my system strings in Customize and the second time was during a reboot after installing the retro iPhone dialer.

    Each time the phone crashed it displayed the connect to iTunes logo.

    Has anyone else had this issue and if so, how did you fix it?

    Thanks in advance.

    and the develpoers from installer and cydia have not had the decentancy to even comment why release something which is so so flawed

  11. steve anderson says

    you cant resize partion to 520 its 547or 552

  12. I just upgraded my iPhone 3g with the 2.0.1 firmware, no problems. One annoying thing tho, when u do the restore settings wizard, it puts all the things on, contacts, messages etc. But when the iPhone restarts it brings up the same wizard in an endless loop? Make sense? Anyone else had this problem?

  13. Hello,

    you already have reports of problems in the maps after upgrading to 2.0.1. I have no problem after that maps updated to 2.0.1.

    It can help with that point?


  14. Someone please help. For some reason my earphones jack volume is very very low. I tried changing my earphones and restoring my iPhone 2gen. Is anyone having this problem? I even tried to clean the earphone jack with a Q tip. My earphone volume is just really low. I know it’s not the earphones becuase I tried them on my iPod and they worked fine.
    What ca. I do?

  15. Do anyone having problem with WiFi after upg to 2.0.1 jailbreak? I can’t connect to my WiFi any more, but when I downgrade to 2.0 jailbreak. I don’t have any problem.
