I had the same problem with my Samsung Galaxy Ace S5830, after accidentally deleting important files while using Titanium Backup (doh!). To fix it, I tried the common solutions already mentioned:
- Factory Reset in Recovery Mode (several times)
- Removing SD Card (several times)
- Removing Battery (several times)
- Many reboots in-between the above
... and still no luck. Same annoying loop with the startup screen rebooting constantly.
Finally, I found the answer: Reset the firmware!
There are a few steps involved, but essentially what you do is the following:
1. Download and unzip the version of ODIN Multi Downloader that is right for your phone. To know which version to use, click here:
I had to get ODIN from a torrent site, and apologies, but I don't have any further information on that. Just know that if you search for "ODIN" on most popular torrent sites you will find it (I got mine on the pirate bay). For more info on how to use ODIN, you can follow these instructions:
2. Run ODIN Multi Downloader, select the *.ops file from the ODIN folder, select "One Package", then select the image file in the ODIN folder (should be obvious).
3. Plug your phone to your PC via a USB cable, then reset the phone holding power and volume DOWN. The phone should then reboot with the message "Downloading..." on it, meaning that it is trying to connect to the ODIN Multi Downloader.
4. If all goes well, you should see messages on ODIN Multi Downloader that show the phone is connected. Then click "Start", and wait for all the tests and flashing to happen. Once the message "Passed" is showing in ODIN, you can unplug your phone.
5. Occassionally, I have to reboot the phone again to reset the factory settings after ODIN is done. To do this, hold down the Start and Power buttons until the phone boots up in recovery mode. Then select "Reset to Factory Settings" (or similar), then reboot.
6. Your phone should now be completely reset to the original firmware and factory settings.
The nice thing about using ODIN now is that I can now try installing different mods, and if I get the same problem again, I can simply boot the phone with Power+Home+VolumeDown, connect it to my PC, and run ODIN 4.38 instructions above, and the firmware is reset within 5 minutes. It's been well worth the few hours of headache I experienced searching high and low on the web to get the above info (and hopefully others find this helpful).
