For me "bricked" in addition to "unusable" means: there is no software way any more to change the fault because the hardware does not boot up into a state where it could read(...) any attempts to change somethinb. The device is now "dark" and does not communicate anymore by no means. Only a hardware change (for example replace some chip) would help. matthias --=20 Matthias Apitz, =E2=9C=89 guru@unixarea.de, =E2=8C=82 http://www.unixarea.d= e/ =F0=9F=93=B1 +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub Thanks to the Soviet Army for the Victory in Stalingrad! -- =D0=9F=D0=BE=D0= =B1=D0=B5=D0=B4=D0=B0 =D0=B2 =D0=A1=D1=82=D0=B0=D0=BB=D0=B8=D0=BD=D0=B3=D1= =80=D0=B0=D0=B4=D1=81=D0=BA=D0=BE=D0=B9 =D0=B1=D0=B8=D1=82=D0=B2=D0=B5! --T4sUOijqQbZv57TR Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEXmn7rBYYViyzy/vBR8z35Hb+nREFAlp4ft4ACgkQR8z35Hb+ nRF9axAAlsX2HtX3YBBCWTBPk37UKgHGZH/HVeIMl0e7pF5Q9UHB7ncPDsBzDHMC YAE1Ayz2opUrDEXm93EhEMxAzviYe73SI1f6LM3II3RZQrQpEDTWFsXisQuATqdT dPvD/IrBFHu033UA9IBOGi7MSsk0OLM0I18kAPJa/Z9AbYhWiDSkG9tHciyOEWlU O7g3Q4BUps0Bk9swtW45gfiBplBjKnU363cTmp73EBZ5VJPE43wYwF1ZUxXxIZJR T1rAjvtEv903H4e3vqRtVwluZrx3rq9tbQJLv1pNitKY5djSziUVsshkdRaXBTkM IzgJSNwecjqdhIGUMYLUVGDOjMJWia78Q4rKv5+6DadhqU7DHTBDwndbMxioKQO/ Yn7uGAEruCZQEJc7OfpLz56vCzctSweOGcSJUHrDHLJkaVvmv4OJYiraHCvNm1ON d6XQJJLUJODc3J1UwgrlCfg5JvWmATkxnafDRSOxeqr/zLO1IoCCZHBDhD7iKf/o 2F53rVLc/9h7qV3bkTSw5hWPrkLOVKzTsr4Z2MX7A52VFjRpqoPbzUjdzv39aLy2 L8LN+Sxz9/UNncOCAIiY/ALaF96CB4UAq94SgxELzB9FFcCWNs/tr4CUTQyA/had Usn4G+8qGj2dUcBB6Mlfa3ddPhKNApjVB6KZrKxlt57TGHHTf3k= =3l76 -----END PGP SIGNATURE----- --T4sUOijqQbZv57TR--
