A few days ago, my samsung started to act funny. I tried to send texts, but my phone just kept saying that it was sending the texts and hours later it would tell me that it failed to send the text. I thought it was weird, but I left it alone. Then, my phone no longer let me download any apps, every time I would try to download an app it would just stay loading without actually making any progress. Finally, I got sick of it so I tried to factory reset my phone. Only now, I can't get past the T-mobile splash screen. I bought this phone off ebay about 10 months ago and when I tried to update it, I was informed that the device was modified even though it was running stock firmware (no sd card at the time). Can someone please tell me how to fix my phone? I don't exactly have the funds to get a new one.

Try re-flashing a stock ROM from Just make sure that the ROM you flash is not older than the ROM currently on the phone.

If you are unsure about the ROM on your phone and there is no warranty left, you could flash a custom recovery and custom ROM too.

I agree with audit13 that you should flash the stock firmware. It's the only way to reliably troubleshoot problems such as this.

I'm assuming it's a T999 or variant. If so rather than go to, you can find all firmware in my thread stickied in the development section and linked in my sig. (Much Faster download and you don't have to register on another site)

As warned above, just do not flash any older firmware (if your already on 4.3) than what is on the device. Only the same or newer.
