How to Fix Corby 2 Infinite Restart Problem

For this post I will going to teach you how to;

  1. Solve Corby 2 infinite restart problem and
  2. Solve Corby 2 hang problem

To do this you will the following application first;
  1. MultiLoader  v5.65 [ DOWNLOAD HERE ]
  2. GTS3850 Flash File (S3850XEKC5) [ DOWNLOAD HERE ]
You will also need;
  1. a computer or laptop to plug your Corby 2 phone and
  2. a USB cable connector
Now here are the simple steps,

1. After you have downloaded the 2 applications above, extract them both.
2. After extracting, setup your Corby 2 phone first. Remove the memory card if there is. If there is sim card then just let it there.
3. Now connect the USB cable connector to your Corby 2 phone and the other end to your computer or laptop.
4. After connecting make sure your Corby 2 phone is ON. Just wait until your computer or laptop install your Corby 2 phone driver to the designated port.
5. After that open the MultiLoader  v5.65 and do the following.
  • Select BRCM2133
  • Check Full Download
  • Click Port Search
  • For the browse file see the image below

6. Note that you will find and browse the files above in the folder of GTS3850 Flash File. After that click the DOWNLOAD button on your MultiLoader  v5.65.

7. After pressing the download button, the MultiLoader  v5.65 will now perform the process of downloading the needed files to repair and flash your Corby 2 phone. This process will display the message below.
Download Start Ch[3]
Bcmboot 123.8KB OK[0.3s]
Boot2 580.4KB OK[1.2s]
Patch_dsp 49.4KB OK[0.2s]
Sysparm_dep 6.2KB OK [0.2s]
Sysparm_ind 80.7KB OK [0.3s]
Wait Reset!!
8. After that you will notice that your Corby 2 phone will restart and it will have a full black screen with a DOWNLOAD message.

9. Don't do anything because the download it not yet finish. Under the Wait Reset!! the following process will follow.

All files complete [398.0s]

10. Now when finished do not do anything let your Corby 2 phone restart once again. After restarting, a Welcome message will be seen, next to that is a message to wait for about 30 seconds. After that your phone now is REPAIRED!

  1. If there is a serial port error check your ports, usb connector and port driver if properly installed.
  2. You may need to restart your laptop or computer after installing the port driver for your Corby 2 if there is a port error while downloading the files in the MultiLoader  v5.65.
  3. If there is still a port error try your other computer or laptop ports.
This troubleshooting is 100% proven and working, because my phone was repaired using this steps. Even though this is a repost, I reposted this troubleshooting for you my fellow Corby 2 users and I hope this one will also help your repair your Corby 2 phone. God bless pals!

August 3, 2013 at 4:40 PM

@alif firdaus

ports are automatically detected by the multiloader, your corby 2 phone (FRAPPE) will appear to a port in the multiloader once your USB port which connects your corby2 to your PC/laptop is successfully installed.

August 4, 2013 at 2:42 AM

maybe i should install samsung kies to find port,

August 30, 2013 at 9:58 AM

After that connect your USB connector to your corby 2 then to your PC.then a large icon of cellphone with arrow will appear in your phone and the port can be used now :)

November 10, 2013 at 6:37 AM

i have downloaded everything, i have followed every instructions. but after I press the DOWNLOAD button, multiloader gives me an error message saying "serial port open error". what does it means?

November 21, 2013 at 7:42 AM

its working. tqvm

November 28, 2013 at 4:59 AM

whenever I do the download mode (menu + vol up + on)..GT-S3850 starts then a green data like appears suddenly then my phone restart and then a blue borded together with a yellow line appears and it says, UPLOAD data to pc..even the multiloader cannot process my only says warning: security fails when I start to download the firmwares I inserted in the multiloader..what should I do..? thanks..!

November 29, 2013 at 2:34 AM

ask ko lng po if mawawala po ba lahat ng files sa phone q? like ung mga messages po.

November 29, 2013 at 5:16 AM

@patricia pamplona

tingin ko po sa sim card naman nasisave ang messages. try mo din po muna insert yung simcard mo sa ibang phone para sure. Yung mga files naman kung may memory card ung phone mo dun mo nalang isave wag sa default memory ng corby 2 mo. para di mabura pag-format mo.

December 6, 2013 at 9:49 PM

I'll try it :)

December 7, 2013 at 12:23 AM

Tnx poh maayos na cp koh tnx poh talaga

Pero poh ang language ay dutch

December 7, 2013 at 11:46 PM

Bkt poh walang cgnal sim ko poh

December 8, 2013 at 3:05 PM

But what if I cant start the phone at all because after I've inserted my sim pin, it'll start itself again and again the same way. :-(

December 8, 2013 at 5:52 PM

My only problem is that the serial port open is always on error even though I've downloaded and installed Kies 3 times and repeated the steps. This is frustrating.

December 25, 2013 at 6:36 AM

Wow! after a lot of tries, finally it worked!! thanks a lot dude!!!

January 20, 2014 at 2:23 AM

Thanks bro ! this is really helped me . i appreciate .

January 21, 2014 at 5:47 PM

@Deanil Vicente

you can check bro whether the samsung driver is properly installed by going to DEVICE MANAGER. If you find a question mark or exclamation point there while installing then you can restart your computer and reinstall the driver. by the way just google the USB DRIVER FOR SAMSUNG MOBILE PHONE to download and install it.

January 27, 2014 at 7:50 PM

F**k! What did you do to my phone!? It's fixed! 3:D Thanks a lot, buddy! :))
