[Q] Samsung Galaxy S2 i9100 Stuck on Boot Screen - Can't Even Flash via Odin topic

Hello,

First of all, im sorry for creating a new thread for this very common issue.
the reason i decided to create a new thread is because i tried everything to solve this problem but no post on the internet was helpful.

so here it goes,
My brother has a galaxy S2 i9100 and it was rooted. few days a go he decided to factory reset the phone before unrooting the device first.
the phone then got stuck on Samsung galaxy S2 boot screen with yellow triangle at the bottom.

since then i have tried following but no method has worked so far...
1. downloaded Odin and the firmware file (tar/MD5)
2. i put the phone in download mode
3. i open Odin and only ticked Auto Reboot and F. Reset Time
4. clicked on PDA and selected the firmware file
5. after it finished checking the firmware in Odin i connected my phone and hit the Start button.
6. the process got stuck on boot.bin.

now, i have tried the above process with the following combinations,
3 different USB cables,
3 different Odin versions (Odin_3.10.0 , Odin3-v1.85 , Odin307)
3 different USB ports on My windows 7 ultimate X64 computer
2 different firmware files downloaded from different websites.
and restarted my PC several times before starting the procedure again.

The process always gets stuck on the same place (boot.bin)
i have also uninstall and reinstall the drivers.
finally i downloaded the Samsung Kies to avoid the driver confusion.
i also ended all the Kies processes from the task manager before running Odin as an Administrator.

i have also fully charged the phone few times and tried the whole procedure many times.
also kept the battery aside for few minutes before starting the procedure


somebody please help i have no ideas left anymore.
sorry for my bad english.



Thanks and Regards
