Hi z4reg, sorry I'm not active on forum these days... However,
I thought the topic is well covered in the thread... here's the procedure:
STEP:1 : Install Nokia PC SUITE is you don't have it already and connect phone with data cable at-least once. Now go to mass storage mode and delete all files and folders named "Private", "Resources", "Sys", "System" etc (Better if you can format your memory card). Now make a backup of ur Contacts and Messages if you need to.
STEP:2 : Download and install JAF from here http://www.mediafire.com/?yn1ywy5cunj
STEP:3 : Download V60.0.003 PNHT Core FOR 113 MB (This is important). Please ask some1 with RM356 to reupload the core.
STEP:4 : Okay, we now have all the files needed
i) The ROFS2 with a name : RM-356_60.0.003_prd.rofs2.V20
ii) The UDA with name : RM-356_60.0.003_000_001_U001.uda.fpsx
iii) The core with name :RM-356_60.0.003_prd.core.c00
STEP:5 : Now rename the CORE exactly like this: RM-356_60.0.003_prd.core.c0r
Okay cool Now copy all this files and put them all in a new folder in your Desktop (Or anywhere else you like)
STEP:6: Now start the OGM JAF (Blue icon on your desktop/start menu) and click on go
Alrighty, an error might come up, just ignore it by pressing OK.
Now ""UNTICK"" EVERYTHING "without" -- "Manual Flash" , "Dead USB" and "Normal mode" (you can even untick Normal mode).
Now it's pretty easy!
----Click MCU button and select that RM-356_60.0.003_prd.core.c0r file in your desktop folder (MCU Button will glow green!)
----Click on PPM button and select RM-356_60.0.003_prd.rofs2.V20 file (PPM button glows green)
----Click on APE Variant and select RM-356_60.0.003_000_001_U001.uda.fpsx (Ape button glows)
---- WE DONT NEED CNT BUTTON
Hmm we are ready to FLASH! So click on the Flash Button and a scary sound effect is played with a warning popup
Click on Yes and in the log window on the bottom of the program, you'll see some lines are being logged. It will eventually display
Searching for phone...
Press Power Button now...
And you do just that! Click on your phones power button once (not too long! just once gently...)
Wait for it to end. When again a scary sound plays and it says Done!!!
You're done finally! Remove the battery from your phone, reinsert and restart your phone!
