He guys, I have the same problem.
I tried to upgrade/update my Samsung galaxy s2 and it had been on 32% for 2 hours and I disconnected the phone.
After that I have Odin mode.
I read the stuff you guys wrote and I tried it.
This is how far I come:
<OSM> Enter CS for MD5..
<OSM> Check MD5.. Do not unplug the cable..
<OSM> Please wait..
<OSM> I727UCLF6_I727ATTLF6_I727UCLF6_HOME.tar.md5 is valid.
<OSM> Checking MD5 finished Sucessfully..
<OSM> Leave CS..
<ID:0/007> Odin v.3 engine (ID:7)..
<ID:0/007> File analysis..
<ID:0/007> Get PIT for mapping..
<ID:0/007> Firmware update start..
<ID:0/007> NAND Write Start!!
<ID:0/007> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
When I boot my phone normaly it says :
"Firmware upgrade encountered an issue. Pleae select recovery mode in Kies and try again"
When I boot my phone: "Volume down - home - power"
It says Odin mode. but it says
" Downloading... Do not turn off target!!
Further than that I cant come.
Oh please help me, my phone is my everything ;$
