s3 bootloop switching to cyanogenmod with cwm As i managed to mess up, I need your help!
I wanted to switch from samsung s3standard 4.3  to cyanogenmod11nightly:

What I did:


with odin flashed CF-Auto-Root-m0-m0xx-gti9300.tar.md5 to get root
backed up data,apps,efs (no nandroid, didnt know at which point that would be done)
because I could find out ho to get the cm-11-20140121-NIGHTLY-i9300.zip to install without a custom recovery, I
reflashed philz_touch_6.07.9-i9300.tar.md5
deleted everything (data/factory reset, then "clean for new ROM", cache, dalvik)
went to Install from .zip -> SD Card -> no CM11 zip file there anymore!! I put it directly in the root of the sdcard


=> now bootloop. In the recovery I see only the standard folders, no usefull .zip

How do I get the CM11 zip again on the phone (or show it up if it is still there)?? And where exactly do i have to put it this time, as my "just in the root" option seemed bad.

I tried this
Problem with updating CyanogenMod - Phone will no finish booting up
but i cant get the ZIP to the phone, its not recognised in Windows as Phone/Folder =(

What is the next step before I brick everything?
As your device supports an external microSD card: take that card, put it into a card-reader (if you don't have one: now's the time to buy it; they come for less than 10 bucks), attach the reader to your PC. Now, copy the file to the root of the card, safely unmount, then put the card back into your phone. You should be able to flash it then.

For what possibly happened: you might have placed the file in the root of the internal SDCard. Recovery is looking on the external card.
