[Q] Network or Phone Problem ?
If my problem is already exist in other thread, please link me to those thread. So, I think nobody have my experience. I'm still completely clueless, but will try to restore to very original condition tomorrow.
I got very weird issue. My phone not work normally today, as it get low signal for a day and that horrible, make me want to test DX modem speed and signal stability.
So, here it is
I already rooted my device, and flash new modem because I install new ROM. After many reading, I read that my original modem DXUBMF8 one is more stable than my modem atm, the XXUBMG9, so I want to test the network speed. I already test my XX modem, and the result is not that bad (for real, it's good anyway), so I'm about to test my original modem. I flashed the modem, and also custom ROM that support it, and, my phone got the signal but it can't connect to the network (the signal shows bar, but not show the H+ with the up & down arrow, or the 3G). Then I tried to restore the stock ROM that I backed up in the first day after I rooted it (it was normal that day), and same things, the signal bar is filled, but no network indicator (H+, H, or the 3G), then I flashed the stock ROM and unroot it with firmware from sammobile.com. Same things happened, the bar is filled, but no network indicator. So it's like my connection is locked in my ROM which people say it's not stable, and haven't try the connection of my original modem.
Anyone experienced or know how to fixed this things ?
