To apply any of the rescue packages you need to unzip the file to the root of a micro sd card and follow the steps in the
wiki.
In other words: copy the folder
OS Firmware with all sub-folder to a Micro SD Card.
Obviously, as you can't access your readers via USB you will have to use any other card-reader to do so.
1.) Charge battery to 100% or you may brick your reader on power failure!!!
2.) Power off the reader (keep power pressed until it asks to shutdown and press yes) if reader is frozen, press RESET button to power it off.
2a) insert Micro-SD-card with folder OS Firmware
3.) Press HOME and MENU simultaneously, keep it pressed while powering on the reader and wait until the progress bar has reached 100%
4.) Now you can release HOME and MENU (this is crucial, don't release earlier!)
5.) Now it will take up to 20min for the rescue process to finish
6.) Reader should reboot automatically, if not - assure that the LED for the micro sd slot does not blink anymore and press RESET. Release and power on the reader.
7.) Reader should now ask for initial settings. Also there should be a file on the internal sd named diag.log, that tells if rescue did complete.
Remark to 6: it will probably not reboot automatically. RESET and restart.
