Back to life
My Galaxy Nexus is back to life again. I made a usb jig and then my phone went automatically to odin mode. After that, I flashed the stock rom via odin. Thank you all of you. Diwad, try it... It surely works...

[Q] help...my samsung galaxy 2 broke

hi, i rooted my samsung galaxy s2 and installed clockworkmod and everything was fine...until i flash the ROM (GINGERMOD). I decided that ROM wasnt for me so i hold on the power button and went into recovery mode. Now my phone goes into recovery mode everything i rs it and i cant exit recovery mode because the HOME OR power button doesnt work. It seems clockworkmod is unreponsive to the buttoms and i cant exit it. when i do a hard boot, it goes back to recovery mode and does the same thing....WHAT do i do? thanks.
Try using volume button to navigate in CWM.
You also could try a usb jig to force it in download mode.

You can't go into download mode? Try taking out your battery, and then going into download mode with vol down + homeĀ“+ power button so you can flash stock ROM via Odin

Galaxy S3 no power button, stuck at boot loop after flashing 6.0 cyanogenmod 13

Hi everyone,
I flashed the newest ROM from cyanogenMod to my old galaxy s3. I did this with the phone still on. After flashing, the phone is stuck in a boot loop. The problem is that I have removed the power button completely because it was faulty(even from the board). Has anyone had the same problem, or has any ideas what to do?
Thanks

I never had the same problem but you can try to hold vol + and home to go in recovery mode, or vol - and home for download mode
I don't have a power button. What you're saying can be done if you press those buttons along with the power one.

buy a USB JIG is a device that automatically enter download mode
Short the power button connections, if you can get at them.

Sure! First set it off by holding volume down and power for more than ten seconds. Then when it it off FAST HOLD BOTH VOLUME BUTTONS. Then connect it to pc.it will show download mode.
Now we gotta flash the stock ROM again. ;c
This will erase everything. Download the stock ROM from somewhere online. Then flash it using Odin. [Use a YouTube guide.] You should be ok. And do not worry.
