[Q] Baseband / Imei / No sim card Trouble topic




I've been researching and fiddling with this phone since Saturday. So here it goes:
First off the cell doesn't recognize it doesn't have a sim, because the "No SIM card, emergency calls only",doesnt show up on home screen.
When i press *#06# , I get a blank IMEI .
Settings, About phone,Software information, more.. Baseband Version "unkown"
Sim Toolkit says " "Sim tollkit is not ready or unsupported"
*#4636#*#* Phone info: "Signal stength: 0 dBm 99asu" ( get -79 dBm 17asu on test phone)
Location: LAC=0 CID=0 (LAC=0 CID=0 on test phone)
Now this is very weird on my test phone(GF's phone) the set prefered network type is GSM/WCDMA/LTE auto, and when I to to set this phone to that setting it will go back to CDMA+LTE/Evdo auto in 2 to 10 seconds (so thats no gsm/sim only cdma).

Now when i connect to Windroid HTC Vivid it will show me the CID, MID, IMEI, SERIAL# AND GETVar (shows everything except unkown baseband there)

Phone is running 4.0.3,software number 3.26.502.56 710Rd, Baseband number 3.26.502.56 CL 302737 ,Bought the phone like this, any help would be apreciated. Saw a post on GSM Forum while googling for similar problems that said, its a cold solder joint on the chipset. So any suggestion tips or tricks, im all ears(eyes).Already did the RUU, tried to get to GB but the file is impossible to get, and heard you cant because of upgradede bootloader.


P.S. can you tell I've been doing a lot of reading?? :laugh:

Also just saw this, dont know if its of any use, On the Test Page, when I press the Edit Key(next to home button) and select "Select Radio Band", the working HTC Vivid shows "Automatic" and "USA Band" , while the broken one displays "Automatic" ,"EURO band" ,"USA Band" ,"Japan Band" ,"AUS Band" AND "AUS2 Band"
