Current status- Note 3 running stock 5.0 Lollipop and root is unavailable. No Mobile Data connectivity
Model SM-N900T (Tmobile) Baseline - N900TUVUFO86
Story- Three days ago I updated from 4.2.2 to Lollipop 5.0 . Shortly thereafter issues appears such as not being able to set PIN security.
Factory resets didn't help. Re-flashing again with 5.0 (BTW, all done through Kies) resolved the issue but other issues appeared. Mobile data connectivity via Tmobile was lost. Couldn't select a Tmobile network- times out. APN is correct + all other settings. I downgraded the phone back to 4.2.2 hoping it would correct the issue but not. Still no mobile data connectivity. Tmobile in-store tech were no help. IMEI appears intact when viewed through *#06#- matches the back of the phone; however, when looking into the details (*#0011#) I see a IMEI FAIL CERT -4. Besides this issue everything else is perfectly fine.
My thoughts are the modem needs to be re-flashed via odin. I found one specifically for Tmobile Note 3 US (from around 2013) on this site. It's a BIN file which I've compressed to a TAR ( suppose I could flash the BIN using phone in odin too). I need some advice here if flashing this modem is the right thing to do. If not, any other suggestions?
Thanks
