SL91, EF81 and other BREW without IMEI

[adfree]

It is possible to use self tweaked/patched Firmware on BREW devices.

But only on special devices.

"Signs"

1.
*#0606#
brings an Errormessage

2. Maybe NO IMEI...

Successfully tested on:
SL91 confirmed
EF81 confirmed
E81 confirmed
SF71, EF82 found but not confirmed yet

NO 256 Byte Signature for AMSS.MBN needed on these devices.

You can for instance remove Camerasound...
Or use SVN 23 on SL91. After u make this Production Key to an Fieldtest Key...

Best Regards

EF82 confirmed.

Now I have found SXG75 Prototype where I can flash selfmade Firmware.
