About two weeks ago I updated my Samsung Galaxy S II to the latest nightly build of Cyanogenmod (through the updates part of the phone). Unfortunately I do not remember the build number of the nightly I updated to - but it must have been near 2014/04/07 (7th april 2014). It made quite a few things not work (It still worked as a phone), so I decided to downgrade to the latest stable build. (Again usint the updater built into the phone)
Now when I turn on my phone, the Samsung Galaxy S II screen comes up. Then it changes to the Cyanogenmod rotating circles boot animation, and stays on that boot animation.
I cannot access recovery mode.
I could not access download mode - but I got a jig and now I can. However when i connect my device in download mode to odin 3 v1.83 to flash it to stock the following error message appears: "USB Device Not Recognised. One of the USB devices attached to the computer has malfunctioned, and Windows dows not recognise it. For assistance in solving this problem, click this message."
I installed the samsung drivers from kies, then uninstalled kies but not the drivers. I disabled my antivirus.I do NOT have the android SDK installed.
Does anyone have any advice on how I can fix my phone?
I rooted the device and installed cm 10.1 a while ago - my custom recovery was CWM
I got a notification that a nightly update was available
I updated to the nightly using the updater built into the phone. That was my only update since i installed cm 10.1. (Nightly was from about 7th April 2014 - not exacty sure)
It worked fine as a phone, but some functions didnt work.
I went back into the built-in updater and chose to DOWNgrade to the latest stable version.
When I turn on the phone now the Samsung Galaxy S II screens appears.Then the cm rotating boot animation appears.
The cm boot animation doesnt stop and the phone doesnt turn on
If I try to enter recovery or download mode using the buttons, it goes to the Galaxy S II screen then the cyanogen boot screen - same as if I wasnt pressing buttons
I bought a Jig which I can use to access download mode.
I have the drivers installed on my computer however I still get an error when trying to connect my phone in download mode to ODIN, which prevents me from flashing stock or recovery.
My other phone works fine when connecting to odin on the same computer
Any help in fixing this is appreciated. cheers
