I Think You Should Have Sent Price To Him In Pm As It Could Earn You A Barn

Is there any Bootloader for SXG75 also ?
How to use it, do I need to remove any IC ?
Thanks in advance.

I don't think so, that you can "remove" something and flash Offline.

I have open 1 EF81, there are no removeable Chips inside...

If you read Manual from QPST 2.7 Build 264:

Quote:

An unsuccessful software download will generally render the phone unusable. The only
recovery is to reprogram the Flash device through the phone’s JTAG interface.

And if u read and see Schematics of EF81... It seems JTAG Interface is missing...

But maybe I'm wrong. Rumours could be so nice.

Did I need for the Bootloader spezial Software and (or) Drivers. I got a dead EF81 and want to Test it.

Hmmm interesting... JTAGs are everytime problem

Btw.:

Devices without IMEI are "unfrozen"...

You can also flash patched/tweaked AMSS.mbn (Firmware).

256 Byte Signature is then not more important...

Check *#0606#

If u get an Errormesage you can try something... For instance remove Camersound...

Confirmed on:
SL91
EF81
E81
SF71 known
EF82 known

@adfree:

great news!

But it's possible only with "unfrozen" EF81s, right?

@ SNSOFTKILLER

Read 3GSwupFU2_manual.pdf

Quote:

keep the # and Power On key pressed for 5 seconds

You need the Download Mode.

If this not work, then NO real chance to Flash again...

@ lalo.lerry

Yes. Only these "special" (unfrozen) devices can flash manipulated Firmware.
But I think this is the first step to "develop" homebrew Firmware

Best Regards
