v300+850mhz question from the hackers bible
(Click here to view the original thread with full colors/images)

hi, i have a TMo v300 and have been very happy with it. It's not flexed or flashed.
I modded the gain_table and i "think" i modded the 850mhz capability.
I'm just alil unclear on one of the directions for modding the 850 capability.

here's a quote from the hacker's bible:
How do I enable 850 MHz support without flexing my T-Mobile phone? Adjust seem 0025, offset 00 so that bits 0, 1, and 3 are all "on". Also, adjust seem 0032, offset 50, bit 0 to "on". If you're a stickler for detail, grab seem 0171_0001 and change the text in there to say "Quad-Band GSM" - this is what displays in the Settings > Phone Status > Other Information > Technology menu. Restart your phone and you'll have 850 MHz support. You will likely not be able to register on any of those towers, though, due to lack of roaming agreements

My question is in regards to seem 0032 bit 50. should you have ONLY bit 0 to "on"? I know when i opened the original seem in xvi32 it had 1,3,4,5 checked "on". Do I leave those on and turn 0 on as well or turn all those off and turn only 0 on???

What's puzzling me is that from TMo's website, using the personal coverage finder, i should b getting good to great service at my home. I'm not gettin jack! All-be-it, I live 1mile up a hill from the freeway with mtns around me. I can see a tower from my house even!!! I'm in a straight line, no obstructions to this tower! Maybe it's a Cingular tower and TMo has no roaming agreements with them in this area?? I used to have Sprint and had no sevice at home either. My sister is on Cingular and gets full bars here! Also, according to wireless advisor, I should have Sprint 800mhz iDen and 1900 CDMA, TMo 1900 GSM , Verizon 1900 CDMA and 800 AMPS CDMA, Cingular 800/1900 GSM, and finally Nextwave 1900 .
What is with the 800mhz? is it in fact an 850mhz tower??

I'm out in Cataic for any locals that are familiar wtih the area.

Thanks,
Randy

First off, set all of the bits in SEEM 0025 to on, hex value "FF". This is the way TMO is now shipping their phones. Guarantees that all bands the phone is capable of supporting are enabled.

Yes, leave the other bits checked on and enable bit 0. Each bit controls a different feature and clearing them could adversely effect your phone (bit 1, for example, controls web access).

I don't get signal at my house so when i make changes i don't see the results till i drive down the hill....
so, on SEEM 0025, i checked them all to ON. when i left home, i had no signal and i had no signal the whole time i was gone(ran errands in a range of approx 40miles where i normally get signal). As for SEEM 0032 i turned bit 0 ON and left 1,3,4,5 on.
One thing i wanna check is if i somehow messed up my backed up seems. here's what i'm showing for my backed seems:
0025-- bits 0 and 3 are on.
0032-- bits 1,3,4,5 are on.
correct me if i'm wrong according to the bible's directions, here's how my edited SEEM should look:
0025--bits 0, 1, and 3 are on
0032--bits 0,1,3,4,5 are on
RIGHT???
So, I'm using p2kman and when i upload the SEEMS in the lower dialog box it will say "uploading seem 0025 Nrecord 001 ok" so i know that's good. i restart the phone and everything's fine. i'll check back tmrrw to see if someone posts the original seem settings to compare to mine.

i'll go park intown tmrrw and bring my laptop and make various seem edits and see which one(s) work. i'll search for networks, try and register and make phone calls, use tzones, then lastly use the data connection with my laptop to see if i can get on the net.

i want to make sure i have the correct seem settings on my backed up seems as well

Thanks!

.

woudln't that depend on what flex version or software version your phone has? do all TMo v300's come from factory with the same versions regardless of manufacture date or whatever? My phone is not flashed or flexed
here's are my versions:
software version: TRIPLETS G_0B.09.1FR_B
flex: GS9V300TMBO2NA105
dsp s/w version: 62E2E000

As SEEM 0025 is only for band control it made sense to me that TMO was enabling all of the bits. However, it may very well be that the other bits in SEEM 0025 on older phones disable features. Quite weird IMHO. Just for reference my V330 hardware information is:

Firmware: R472_G_08.18.1DR
Flex: GSPV330TMB01NA0E6
DSP: 62313100

You definitely have SEEM 0032 configured correctly now. As for SEEM 0025, simply go back and set bits 0, 1 and 3 and clear everything else (hex value 0B). If that brings back reception then the other bits are definitely turning something off in the older phones.

ah! you''re on a v330, not a 300 so you're already quadband.
well, i have everything set to what the bible specifies and everythings working fine.

when i had everything checked in SEEM 0025 i did notice in the menu for NETWORK SETUP that for the BAND it only had teh option for automatic. when i switched it to what the bible specified it went to having automatic, 850/1900, and 900/1800. I set this to automatic. SEARCH TYPE is also set to automatic, and i have speed set to slow. I read somewhere that you could gain alil xtra battery life by switching this to slow so that's what i did.

i still don't pick up a signal at home so i'm guessing TMo has no roaming agreements with any local towers. I'm going to call TMo Customer Srvc. today and try and talk to someone about it, cz on the TMo website, PERSONAL COVERAGE map thingie it shows me clearly in the green with good signal.

This leaves me with several conclusions:
a- Maybe doing the SEEM edits to 0025 and 0032 don't give the v300 quad band capability like ppl state.
b- maybe i need to flex or flash for those seem edits to work.
c- the personal coverage map is not realistic and i just don't get signal here from TMos tower or anyone else's. Like I said, my sister has Cingular and has full bars in the house! Sprint has little to no srvc.

any other ideas?

Yes my V330 is quad-band but only because it shipped after July 1, 2005. As I understand it, had it shipped before then, TMO would have disabled 850 on it.

Do you have 911 service when you have "no signal"? This would at least tell you if you are getting any GSM signals. If you want to enable the phone to display "Emergency Only" under those circumstances, you need to set bit 6 to on in offset 4A of SEEM 0032 (from http://www.xlr8.us/hofo/map.txt. That will at least tell you if the phone is getting a GSM signal that you cannot roam on.

Yup! I see EMERGENCY ONLY displayed.

Then you are receiving a GSM signal, either on 850 or 1900, but you having no roaming rights.
