Fix: Hash Sum Mismatch Cydia Error While Installing Installous 5

Hash Sum MismatchEarlier we talked about Installous 5, which has one of the major feature now (Download files via torrent), but many users faced issues while installing Installous 5. Earlier, an update was not showing in my jailbroken iPhone 4 and later when Installous 5 update was visible, on Installing I was getting this error : Hash sum mismatch error. Here are some of the workaround to fix this issue.

2 Ways to fix Hash sum Mismatch error in Cydia:

If you getting this error for the first time, I suggest you to retry or try downloading any other app in Cydia and see if it works. Else, here are some of the possible solutions which you can try.


This is the basic step and this worked fine for me. I closed all the apps, restarted my iPhone and tried updating to Installous5 and it worked for me. Even in forums, many users reported the same and it’s working for them without any issue.

Use Alternate source:

Usually we use http://cydia.hackulo.us to install Installous, but you can also try alternate cydia sources like SinfuliPhonerepo. here is the repo address: http://sinfuliphonerepo.com

simply go to Cydia > Sources > Edit > Add and add the following source and then search Installous 5 under it, and install. I tried this method in iPad 2, and it worked for me.

Reinstall Installous:

Another method is to delete installous and remove it’s source and re-add it. This is one method, which I have not tried but many users reported it worked for them.

I tried the first 2 fix for fixing Hash sum error in Cydia and it worked for me. Last but not the least, if nothing works for you: You can start from scratch by re-jailbreaking your phone and installing Installous on fresh device.  Though, I suggest to use this only, when nothing works for you.

Here are few more fixes, which are suggested by users in forum:

Reset Network settings:

You can try resetting your network settings in iPhone or iPad and it may work. Also, reboot your modem once.

Reload Cydia:

On the cydia homepage, reload it to update it and then try and see is you still getting “hash sum mismatch error“.

I tried the torrent feature and for now, there are very few apps with magnet link available, but in coming days we can expect way more. Anyways, do let me know which solution worked for you and if any of these worked (It should), don’t forget to share this post on Facebook and Google plus.

Apple iPhone and iPod Touch Forever Confused over Daylight Saving Time (DST)

Ever since the United States and Canada have made an early shift to daylight saving time (DST) it has caused DST-related malfunctions across several iPhone and iPod users across the globe.

There is no known solution to this problem. While some users have reported that simply restarting the phone seemed to solve the problem, no has found an exact fix to this issue. While initially the problem was perceived to be with the 4G devices it seems that even 3G and earlier Gen users were also affected. This problem is not specific to any version of the Apple iPhone or iPod Touch nor are they specific to any network carriers. We have understood reading through the Apple forums that the Clock application on the devices has been displaying very erratic behaviour.

Users have reported that their phones kept adjusting their time back and forth automatically and then later self-corrected back to the correct time. Behavior such as this from the Apple devices has caused several users to be late for work and others to wake up a few hours before their alarms were actually scheduled to go off.

A user from the state of Arizona, the only state in the US which does not observe DST claimed “When I got up on Sunday morning, my 3GS showed an hour later” Later his wife informed him that the phone was showing the correct time. The phone had managed to self-correct within a couple of hours after it started showing the wrong time. It’s amusing to find this happening in areas where there is no need for any DST corrections.

Has anyone here faced this problem? If you have observed this happening with your Apple devices please write to us and tell us what exactly happened and how you went about finding a solution to this weird issue.

Fixing iPhone update server could not be contacted Issue

In my earlier post I told you about iPhone Error 1603 issue and here is another issue which I faced while  updating my iPhone to iOS 4.1. After few unsuccessful update, I started getting message on my iTunes:

iPhone Update server could not be contacted.


This is again an unusual error as everything was working fine for me and all of a sudden I started getting this error. To resolve this issue I followed following steps, which might help you to resolve iPhone update server issue:

  • Check your Internet setting. You should not be connected via Proxy.
  • Restart your modem.
  • Restart your computer.

Out of above three, for me restarting my computer fixed the issue. If you are also stuck with iPhone update server could not be contacted issue, I would suggest restart your laptop/computer and it might work for you as well.

iPhone Restore/Update Error 1603 [Solved]

I was trying to upgrade my iPhone 4 to iOS 4.1. Since it’s an unlocked iPhone, upgrade should not be an issue, but my iPhone started giving error 1004 and error 21. Initially I was trying to update using Windows system but after this issue, I moved to Mac.


While trying to update my iPhone, I started getting Error 1603 which is unusual error. I tried lots of time to restore and fix this issue (As suggested by many other forum) but it didn’t helped.

Luckily after some hit and trial I was able to fix this issue by removing my sim card and sim tray and updating it again. Voila! within minutes my iPhone 4 is updated to iOS 4.1.

So if you are also stuck in the same situation like me, I would suggest remove your sim tray and try updating your iPhone.

Do let us know if this doesn’t helped you in your case.
