Hello there,

I just rooted and flashed a custom recovery to my S3 today. Afterwards, I installed CyanogenMod through the CWM recovery and rebooted, however,after the reboot the device powered off completely. Now when I try to turn on the device I get a grey battery icon with a static circle on it, and it does not proceed any further. I cannot access recovery mode or even get to the Samsung loading screen. Plugging the device into the wall charger doesn't seem to be doing anything as it has been 'charging' for over 30 minutes and still does not power on. I've been scouring the net for hours looking for answers, but the few people who seem to have the same problem have not found any sort of resolution. There are all sorts of tricks people are suggesting such as putting your battery in and plugging the cable in, vice versa..etc but nothing seems to work. The phone was working just fine and the battery still had a good 30-40% charge when this happened. Does anyone know what the issue could be? I cannot even get it serviced because I had JUST rooted/custom recovery'd it when this happened, so just my luck with that. If anyone could help me it would mean a lot. Thank you for reading.

Regards,
Mike

Copy and paste the name of the zip that you downloaded and flashed for me so I can better determine what you did bud, I don't want to say hard brick because this could be battery cells going bad coincidentally

Hello there,

Thanks for the reply. I followed the instructions as per this thread:

http://forum.xda-developers.com/showthread.php?t=2179330

The CWM mod version I got from following Step 2 of that guide, which led me to this: http://www.epiccm.org/2012/06/cwm-recovery-on-all-sgs3-lte-variants.html

Afterwards, everything seemed to be working fine, so I grabbed a copy of the official CM latest nightly for my device, wiped/factory reset, and installed the ROM + gapps. After I reboot, the phone shut off, and this has been going on since. I am able to get into download mode, as I have just discovered, but I cannot get into recovery mode or turn the phone on past this mysterious grey battery icon.

Thanks for your time,
-Mike

kk download you're stock firmware and flash it in odin, something went wrong my friend so you're going to have to start over

stock roms are here http://forum.xda-developers.com/showthread.php?t=1968625

the good news is download mode = soft brick so you are in luck! My guess is the ROM was corrupt or just a very horrible flash =/

Thanks very much! I was able to use the stock firmware in conjunction with Odin to get myself back up and running!

Now the issue remains, is there any way to install CM 10~ on this device? I cannot find a proper version of CWM aside from the 'universal' one which I mentioned above, however, if I try and flash any version of CM using that recovery, it gives me a Status 7 error, which people say is due to an old recovery version. Any idea as to where I can find a working (new) version of CWM for this device?

Kind Regards,
Mike

I've solved the issue. Thanks for all the help.

The problem was that apparently I had an outdated bootloader which wasn't compatible with newer versions of CM and CWM. I installed the new bootloader from a thread here in the S3 forums and then flashed a new version of CWM and managed to get CM running.

I'm having new, unrelated issues now, but I'm sure I will be able to solve those.

Thanks again
