[akauts]

Please help,...

i upgraded the SX56 RSU to 4.21 version and upgraded the ROM to WM2003SE. after upgraded, it was resulting "NO GSM DETECTED" and the Phone Function cannot be used.

i follow an instruction from this forum http://wiki.xda-developers.com/index.php?pagename=Wallaby_HT_GSMError

And followed some steps and succeded, and constinued the next step but when i tried to upgraded the RSU to 4.16 there was a message "Flash Failed, Press OK...".
im sure that my battery was 100% charged,... what else???

pls someone help me to make the SX56 Phone Function could be use again,...

Thank You

SX-56 is PWA10B1, and the 4.21 radio stack is for PWA10A1 devices...you need the A20.10 rom from here: ftp://xda:xda@ftp.xda-developers.com/Wallaby/Radio_Stack/RSU_VA20.10_PPC.zip
I'm not sure you can fix it yourself, though.

Note: you can check your device version (PWA10B1 or PWA10A1) at start -> settings -> device information

KTamas,
Thanks for your advice,... i'll try;

============================================

KTamas,
it was a funny thing, i check the version in Device Information, it shown PWA10A1, but at the rear sticker of SX56 it shown PWA10B1.

Anyway, i downloaded RSU from your given link, and upgrade the RSU.

The process was stopped at 83%; hanging up around 10 minutes and then a notification appears "Flash Failed, Press OK to..."

please advice,..

Thanks

Uhm, you should not do that upgrade cause it seems you have pwa10a1 then...i have no ideas, sorry.

That´s WRONG. The output of the system (settins -> device -> ...) depends on the ROM installed. Only definitly thing is the rear sticker.
I´m sure you can modify a rom, so that there will be displayed "Blablabla".
So to confitm which device you have only check the rear sticker....

Finally, Its working...
May Steps were:
1. I downgraded SX56's ROM to its Original ROM
2. I installed the RSU Version A20.10 (Still Not Working)
3. I Installed the WM2003SE (Cooked in Stefans Kitchen)
4. Then, I installed the RSU Version 6.24.20 (Still Not Working)
5. And Then, I installed the RSU Version 6.25.02
And its working...

I dont understand that there was Nothing-Happened/Not-Success when i installed RSU Version 6.25.02 at the first time i assumed the SX56's GSM Error as adviced in forum.

Anyway, Thanks to Stefans who help me alot and also KTamas.

Best Regards
