GSM-Forum - S3850 hang on logo [Solved]

Hi everyone!

I had Samsung S3850 hang on Samsung logo after Chinese firmware, did not start even with original firmware

I don't want to say the best boxes but the only SOLUTION. I have all JTAG Boxes: ORT, Riff, GPG JTAG & SMTi Did try every possible solution to fix this Samsung BADA phone, but after 2 days of suffering finally thanx to Medusa & Octopus Box, especially to product manager & supporter

However here is very simple SOLUTION:

1.Download & install the latest Medusa & Octopus software.
2.Solder & connect S3850 in Advance Mode
3.Full flash erase & disconnect
4.Connect in Easy Repair Mode
5.Repair BOOT with new downloaded Repair.mf file
6.Disconnect!
7.Now download S3850 firmware from support
8.Hold volume up(+) + Call then press Power to enter Download Mode
9.Flash with Octopus Box

After all when your phone is on & working, think how deep Medusa Box can go into the phone.
