I have this behavior in my u20i phone that the phone will not boot. When i connect it to my PC, the PC detects the phone momentarily for around 5 seconds and then it disconnects and this will continue until i disconnect it. Does this mean my phone is bricked? Is this what a bootloop is? I read many threads on this forum, and for whoever was facing the problem of bootloop, he was atleast getting SE logo.
Now coming to my problem, i used s1tool to get the present details of my phone and it shows the following:
RUNNING S1_EROM VER "R8A029"
SOFTWARE AID: 0001
LOADER AID: 0001
FLASH ID: "0020/00BC"
LOADER VERSION: "R4A045"
MODEL (from GDFS): U20i
SOFTWARE VERSION: 1235-3411_2.1.1.A.0.6
CUSTOM VERSION: 1238-7170_R4B
SEMC SIMLOCK CERTIFICATE
The loader version tells me that the bootloader is not unlocked. Tried using SEUS update service to fix my phone back, but after completion, i still am stuck with this boot-looping. Any other suggestions? Any more information required to debug my problem? I had installed a custom rom which was working well (MiniCM7Pro_V21) until i restarted my phone which is when i got this problem. (had got a problem like this before but using SEUS had worked that time)
I can enter the flashmode of the phone atleast but thats it (this gives me some glimmer of hope )
My last resort will be to give my phone to the SE service guys but i wanna know what the problem is before i give it to them.
