I have an international n7100

After upgraded to 4.3. I noticed a significant signal strength decreased

Now i cant receive 3g signal inside my house. When im on 4.1.2 it get full bar strength

I tried to downgrade to 4.1.2 stock and try several aosp based rom but it still the same as 4.3 stock

I tried flash different baseband. Still have the problem :(


Anyone have the same issue as mine??? Plz help me :). Tks in adv

My friends have 4.1.2 gs3 and he didnt have the same problem as mine. May be the bootloader involved here. I dont know :(

Was on official stock Nordic 4.1.2 ROM, flashed Faria's deknoxed international 4.3 ROM & got exactly the same result as you.
Followed the roll back procedure in his description, reflashed original Nordic stock 4.1.2 again, & reception is back to normal.
No doubt it's the modem that's causing the decrease in reception. Thank God it's not irreversible.....

Here you go. It's the downgrade ROM (by Faria) that I used:

http://xdaforums.com/devdb/project/dl/?id=3117&task=get

After successful flashing of the above ROM, flash your country/area's
official 4.1.2 ROM, and you're done. You will need to wipe the device
before flashing Faria's downgrade ROM. This worked on my phone.

The Nordic ROM that I flashed after using Faria's downgrade ROM:
N7100XXDMG1_N7100OXXDMG1_N7100XXDMF1_HOME.tar
It's available through Sammobile, or similar.

Good luck, dude! :good:

I tried flash via odin PC but it keep showing "failed"
I flashed tar.md5 via mobile odin, it worked but the rom and the baseband still have signal problem like 4.3 roms


I dont know what to do next, tried many times and failed :(

Yes, you must flash the correct ROM for your country/area
after flashing Faria's one. Then you get the correct modem.
Get the appropriate ROM on your phone, & you'll be fine.
