[FIXED] - please help - stuck on permanent bootloop trying to return to stock

[suparuss]

Hi,
I've rooted my old Galaxy S2 plenty of times and flashed new ROMs before with no issues.

Last week I did it for my friend, we flashed a new ROM (NEAT) and kernel. He loved the look of it but found it too unstable apparently. He asked me today to put him back to original (stock).

I put the phone into download mode and flashed the latest firmware via Odin (I flashed the January 2013 firmware from this page Firmwares | SamMobile).

It's now stuck on the boot logo. What do I do?
I CAN get into download mode

He's UK, T-mobile and wants stock firmware

As far as I understood from XDA, all I needed was the stock firmware and download mode with Odin. But that doesn't seem to have worked

I definitely haven't ticked 'repartition' or anything

boot into recovery and , Select Wipe data, Wipe cache
Go to Advance and Select Wipe dalvik cache, see if will boot after that, if not

Go to Mounts and storage, select Format system

Boot into download and reflash

It's possibly a conflict going from neat jelly bean back to ics(latest T-Mobile stock) as kelis suggests, I'd do complete wipes in recovery if possible, if need be reroot it using siyah if required, do wipes and reflash stock(though if the initial stock flash worked, rooting with siyah may be able to get it working, just be stock Rom rooted!)

Thanks, I couldn't get into recovery or I'd have tried that. But I found information about performing a hard reset (volume up, home, power - hold for 5 seconds and then release).

The screen looked like recovery but had different menu items. I chose the factory reset option and it booted first time!

Hope this helps someone else one day

That is recovery as far as im aware ? but stock recovery not CWM which was probably lost when you flashed the stock ROM

Glad you got it sorted either way
