[Q] Huawei Honor u8860 Big Problem

Hi everyone

I have big problem with my honor
i read this forum about 3 days but i can't find anything that helps me

problem is that i bricked my phone
i was trying to change my stock ROM to custom
and i read that i need to flash custom recovery.img and also unlock bootloader (pink screen)

i couldn't install CWM and unlock bootloader
so i rooted my phone (everything goes fine)
then i install root explorer and renamed stock recovery.img to recovery-original.img (placed in /.cust_backup/image/)
next i placed custom recovery.img to /.cust_backup/image/
i think this will give me a CWM but my phone stuck

when i'm trying to power my phone i see huawei logo and then i see error "signature verification failed"
and nothing happen next :(

i was trying to flash new rom from sdcard (vol+ vol- power)
but i have update failed and in dload folder is .log

dload_sd_ram_data_proc->(retry >= DLOAD_RETRY) failed!

i was trying about 50 times with different Roms and allways have "update failed" at step 2/2

i have locked bootloader so i don't see system partition

i was trying also to flash some downgrade .app and b928 pink screen unlocker
but here also give me message "update failed"

I have
HUAWEI HONOR U8860
ROM: ICS B928
BOOTLOADER: Locked
Kernel: 3.0.8 but i'm not sure
Phone purchased in Europe


is there any option what can i do?
windows don't recognize my phone
adb toolkit also don't see my device :(

mayebe there is a program that let me go inside my system partition and change recovery.img back?

help please!!
