[Q] Stuck in download mode and broken Volume Buttons - Galaxy S II Q&A, Help & Troubleshooting

Hello there experts,
The volume buttons of my S2 don't work at all. I bought it 2nd handed and the seller told me this beforehand. It seems they were broken in the process of replacing the screen, God knows who made such mistake.
I installed cyanogenmod with CM installer, as it does the job almost automatically without the need to go to the Download mode.
Once everything was installed and set up I thought, well let's try to remove that yellow triangle image...
After installing Triangle Away, it brought me to the download mode. I knew it was risky but I thought the phone would restart normally.
If I remove the battery, it'd always go back to download mode, and there is no way to start the phone normally.
as I'm unable to either press VOL up / down, i'm stuck in the download mode.
The only solution that comes to mind is disassembling the phonem, play with the volume buttons and see what's happening there, and try to fix it (if there's even a possible fix)
Does that look like it could be fixed? or it would need to replace and solder something else?
also, is there a way to get rid from the DL mode with some USB method on the PC? also flashing the phone as it is right now is impossible I guess.

this is what I found in the volume parts,
it's the first time I dare to disassemble a device like this. I have no clue about this kind of stuff;

Try ADB Fastboot commands. Maybe it detects S2 in Download Mode. But not sure about that. First of all,
Download Samsung USB Drivers.
Download Minimal ADB & Fastboot
Connect USB Cable
Open that command line tool
Issue command 'adb devices' or 'fastboot devices'. If it detects your phone, your IMEI will be shown. Then try,
ADB Fastboot Reboot System
If all good, your S2 will be rebooted.(presuming that you're Rooted). If it doesn't you have to repair those keys or try to press them by some sort of sharp thing but easy you go, otherwise you will be damaging your phone. I recommend you ti get them repaired

Thanks for your help.
Yes I was root, the solution you gave looks like it could have worked to get rid from the download mode.
Anyways, the flex that connects the buttons internally was broken, maybe this was a good thing that had to happen to get it repaired, as sooner or later I'd have to do that.
Finally I found a guy who is a beast at these things and he had lots of parts of S2's, so he repaired it in about 10 minutes.
Now I have a fully functional S2. It's still a good device in my opinion.
I bought it 2nd handed for a lower price that any chinese phone, good cam and speakers... makes me wonder if we should get ex-flagship devices instead of newer chinese cheap phones. I paid only 55euros for this phone, I know it's usually more expensive. After using a chinese android phone, my experience is much better with the S2.
So far I'm using cyanogenmod11 as my first rom. I know this question can be dumb and repetitive, but could you tell me what are the best roms/rom in your honest opinion? As usually, the smoothest running and more lasting battery are the most demanding needs.
Thanks again man!

Thats good to hear that. Yeah chinese phones are not good at all. Samsung S2 is a demanding phone still. I am also using S2.
As you asked about ROMs, personally i haven't rooted my S2. But in my opinion, i am listing three links about Top Custom ROMs. Visit them you'll find something for your S2.

I'm not sure about the s2 but in other devices, the stock updated roms+root access have always been the best configuration. Thing is I don't like TouchWhiz much.
Thanks for the info man. I'll check that out.
