Lemur 5.3 update won´t start

Rayk Nov 21, 2015 12:45PM CET

I just updated to Lemur 5.3 via AppStore on an ipad running iOS9.1. Since then Lemur crashes upon start and closes. Can i downgrade until you´ve fixed that? The previous version was running fine.

only way to "downgrade" is if you have made a backup of your iPhone/iPad with a previous Version on Lemur which was running fine for you. Then yes.
1. Delete Lemur from iOS Device.
2. Connect your IOS Device with itunes (via Cable or WIFI)
3. Besure on iTunes "Automatically Backup" is deactivated)
4. re-install Lemur from iTunes to your iOS Device.

I Just did it. Takes 2 Minutes and works.

me too - seems OK on iPhone5s but not join iPad3. I tried everything including complete reset (not a restore) of iPad and only default apps plus Lemur... luckily had an old backup on iTunes so I'm back with 5.2.2 Just wasted most of the day.

I just updated to Lemur 5.3 via AppStore on an Ipad2 running iOS9.1. Since then Lemur crashes upon start and closes. My lemur oldversion was running very well and perfect.
I use Lemur every day and now I am very angry! Grrrrrrr!

Claude, what device did you grab that backup for? was it perhaps a 16gb iPad 2? if so wondering if you could maybe upload the backup image to drop box or something. I never made a backup of my device. Not one that had an older version of lemur.

it works from an iPhone restore as well. So if you have it on your iPhone do this.

1. create a backup from the iPhone
2. delete lemur app
3. restore from iPhone back up
4. it will download the iPad 5.2.2 version

PHEW I can now gig.

Same. iPad 3 and iPhone 6 Plus both iOS 9.1. Seems to open then immediately goes unfocused on iPad. On iPhone it behaves differently. Opens normally can access the templates but goes to unfocused when I try to display iPad template only opens ok otherwise. Try to display iPad template and it goes unfocused. Still active and loaded in memory on both. Can be quit normally by double clicking button and swiping up. Seems like maybe iPad templates are messed up.

***Lemur 5.3 update crashes - advice***

Dear Lemur users. A significant number of users are experiencing crash on startup with the iOS 5.3 update. We recommend that existing users do not update for the moment. We’re hugely sorry about this - the update was tested properly with all of our in-house devices, but there are so many device configurations out in the real world that occasionally new issues arise on release. Please accept our sincere apologies.


If you are experiencing crashes you will, of course, be able to download the fixed version for free shortly.


If you have already updated, are experiencing crashes, and have an iTunes backup, please follow this procedure to roll back to the previous working version:
1- Delete crashing app from your device
2- Click on Apps section in iTunes then click on My iPhone Apps or My iPad Apps on the top bar
3- Locate Lemur app, this should be a previously backed up version
4- Drag Lemur onto your iPhone or iPad device
5- Sync your device

If you don't have a backup then, unfortunately, you will need to wait for the update which we're rushing to the store as fast as we can. Unfortunately the App Store offers us no mechanism to roll back the active download to the previous version.

Thanks so much for your patience!

I found Vs 5.2 in my iTunes Mobile Apps folder on Time Machine. I restored it to my current iTunes Mobile Apps folder, so I wound up with two Lemurs in my Mobile Apps Folder, 5.2 and 5.3. When I deleted the Lemur app on my iPad, then connected to my Mac, the only app it would look at was 5.3, so I deleted it from the iTunes Mobile Apps folder, leaving 5.2 in the folder. That one will not load to the iPad. I have no clue as to why. Anyone have a suggestion. I'd even email you the 5.2 version if we could figure this out.

Indeed, the latest version (5.3.1) is not running properly on iPad 1 (iOS 5.1.1) for some users. I’m very aware of the inconvenience, please accept our sincere apologies. Our dev team is looking into this right now and we're hoping to have an update as soon as possible for this device.

Thanks for the update - I just updated (on an iPad 1 (iOS 5.1.1) and discovered the crash - and discovered I didn't have a back up - happy to wait for the fix - I was worried that I might have just nuked Lemur and then found iPad 1 was no longer supported - super happy that you're still supporting the older hardware, as Lemur is primarily what I've been keeping this older iPad for....

If 5.3.2 is crashing on your iPad 2 (and assuming your unit is not jailbroken), try the following. Delete Lemur from your iPad 2. Power-off your iPad 2, and reboot. Download Lemur from the App Store and try again. If it is still crashing, please email with your crash report. After syncing your device in iTunes you should find recent crashlogs at ~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>
