You can try adding the ro.ril.gprclass line.

Since everyone is concerned with changing the hsxpa line at the top to 3 when the ace RF line is already set to 3, I'm betting ace RF is ignored.

Open up Terminal Emulator

Become root:

$ su -

Mount /system as rw

#mount -o remount,rw /system

Backup current build.prop

#cp /system/build.prop /system/build.prop.bak

Now use VI to edit the build.prop

#vi /system/build.prop

I use the navigation keys - h,j,k,l and remember that Vol down + 1 is escape and you should be fine.

[HTC Inspire 4G] dacket84:
Does flashing any roms or radios change this file at all? If not then I'm getting these speeds:

With these (unedited by me) settings:

ro.ril.enable.dtm=0

ro.ril.gprsclass=12

ro.ril.hsdpa.category=14

ro.ril.hsupa.category=7

ro.ril.hsxpa=3

Stock, unless edited by flashing roms or radios (because thats all I've done sinse having this phone as of Tuesday)

Also is there any way to enable the 850mhz band on these? With my Captivate once I used an 850mhz rom I have gotten incredible signal and speed everywhere opposed to stock where I would be half bars most places. Which is on par to the signal I'm getting with this phone now.
[HTC Inspire 4G] pmelt:
Thanks for the tip. Although on my phone to remount rw I needed to specify the device, ie:

mount -o remount,rw /dev/block/mmcblk0p25 /system

It should also be noted that busybox needs to be installed if not already.

I'm on 208 and using the dual APN's as well as these build edits I get up to 7mbps
[HTC Inspire 4G] CYRAXDroid:
is that a common settings to do? or what should you set it to? thanks still learning about this editing build stuff lol

Well Im trying out those settings and see what that brings..

I usually set mine to...

Not sure which is better...
[HTC Inspire 4G] XsceneXhippieX:
I'm getting 5000+ kbps or 5 mbps or whatever you want to call it, but some are getting 7 mbps, how do I use this dual apn and what values in the build.prop are being used to achieve such speeds, I'm pretty fluent in these simple tweaks all I'm looking for is a simple explanation because there are basically 20 pages of different values and I can't determine which ones will get 7 mbps down from the clutter, I'm sorry I just got this phone and I'm new to these threads, coming from a captivate getting similar download speeds and that confuses me because the inspire is built to handle faster data, not the same speed as the captivate

[HTC Inspire 4G] XsceneXhippieX:
i ended up using the "4g" H+ area values (with 112 in hsdpa and 12 in hsupa and wideband=1 and hsxpa=3, a simple search will show the post in this thread) and im getting the **most consistent ive seen personally** high-er data speeds of 2.6-3.6mbps down, and a VERY consistent 1.1mbps up (like every single test) which is a lot better than the latest nightly's stock settings that were capping at .5up and 2.4ish down for me.. i still envy these 5+mbps down speeds and wish to know what i might change to achieve this massively high speed.

anybody haveany input? i am debating reverting back to the OP values because they gave me similar speeds, what i find odd is on nightly 250 (NOTHING CHANGED IN THE BUILD PROP) i was getting *consistent* 5-5.1mbps down and now i cant even hit 4.. maybe its just AT&T but i would like to know how to "unlock" the full potential of my inspire's hardware.. from the looks of things so would everybody here on this thread lol
[HTC Inspire 4G] HTCinspiration:
I get 5MB to 6MB down & 1.2 up consistantly with the settings i posted on the last page a while back & using the dual apn settings posted in the stickies on the Inspire dev thread although i also have really good luck using the 3G Turbocharger script by Zepplinrox. I'd definitely recommend it to find the optimal setting for your device & area.
[HTC Inspire 4G] XsceneXhippieX:
Dual apn sounds fishy to me, I've seen and read into the thread and understand why it was implemented though and I might give it a try, may I ask you this one Queston about the 3g turbocharger script (that I have been repeatedly using in my quest for faster data btw) being: fast, faster, fastest, experimental 1, or experimental 2 works well for you? My speeds have varied so much on every thing I've tried I'm beginning to think I'll never hit 5mbps again.. But yeah I will try your settings out now and report back later
[HTC Inspire 4G] HTCinspiration:
The dual apn's is a good thing. The only thing about them is that it really depends on ur network & location whether they will make a major difference or none at all but they should never have a negative effect, worst case is no chang in speeds. Some networks need dual apn settings & some don't. Our Inspire came from AT&T with dual APN's after all. And personally, i seem to get the best, most cnsistant speeds with options 2 & 3(faster & fastest). I get amazing speeds sometimes with the experimentals but I also get really bad speeds. Just very inconsistant for me. But again, it really comes down to ur area :')
[HTC Inspire 4G] HTCinspiration:
And i should also add that a lot of people(myself included), are getting really good speeds with the Absolution ROM. They've got a pretty sweet setup that seems to benefit most people that try it. Not tn mention it's just a sweet ass ROM through & through. And this is the only ROM that I do NOT use the dual APN setup. For whatever reason the speeds seem alot more consistant with the single APN setup on Absolution :')
[HTC Inspire 4G] rasroygbiv:
Thanks for the recommendation! :cool:
[HTC Inspire 4G] HTCinspiration:
My pleasure buddy. Thanks for the "sweet ass" ROM! Lol :')
[HTC Inspire 4G] henrybravo:
Not sure why you think the dual APN is "fishy" - the stock ROM comes with the same dual APN configuration.
[HTC Inspire 4G] rasroygbiv:
And the dual apn setup works better on almost every ROM, in my experience!
[HTC Inspire 4G] henrybravo:
Indeed you are correct my friend. ;)
[HTC Inspire 4G] MarkF001:
I have had very good results with the following settings:

ro.ril.enable.dtm=1

ro.ril.gprsclass=12

ro.ril.hsdpa.category=14

ro.ril.hsupa.category=7

ro.ril.hsxpa=3

And one AP

The same settings with two APs, can achieve the same speeds; but are not as consistent.

I usually get between 6 and 8 mbs down and

Around 1 mbs up.

You mileage will vary by area.

Remember setting need two reboots to take affect.
[HTC Inspire 4G] berserkerx87:
Can I ask is it just my area or am I doing something wrong to not achieve the speeds that you guys get? I pull down at best a 2.5 DL and a 1.36 Up.

Also my up speed is faster than my DL speed a lot of times as well.

I am using the 26.13.04.19_M radio with the matching RIL.

My build prop is as follows

grpsclass=12

hsdpa=28

hsupa=7

hsxpa=3

I saw in a post that supposedly the 28 is how you really get the 4g network with att.
[HTC Inspire 4G] dark_angelfighter17:
finally got 4g in my area!

ATT FINALLY finished there backhaul here in Fayetteville NC and im getting a consistent 4-5.5mbps down and 1-2 up with regular build.prop settings. Before, I had to edit my settings to get anywhere near 4mbps down and I would get it only at night. Im about to try new settings to see just exactly how fast it really is.
[HTC Inspire 4G] fowenati:
my bet is anywhere between 4-7 during peak hours and depending if your in 4G, up to 10mbps in off-peak hours.
[HTC Inspire 4G] PsionX:
Can you share your all build.prop... i have some wifi & connection problem, so i want to test a good one !
[HTC Inspire 4G] dark_angelfighter17:
4 to 7 seems to be what imm getting at the momment but signal is verry flakey at best. it keeps bouncing from 3g to 4g towers but even 3g only towers seem faster. Imma try a new radio/ril combo and maby that will help. I would LOVE 10mbps lol.

1 more note, ATT is sending me txts about data throttleing so I dont kno if that is accually affecting my tests... probally wont kno for another week or 2 when my plan rolls over to next month...
[HTC Inspire 4G] stretch148:
Just did this. The only two values I had to change were the hsdpa and hsupa....did speed test last night vs after this fix.

1332kbps down vs 2979kbps

557kbps up vs 1116kbps

THANK YOU!
[HTC Inspire 4G] dark_angelfighter17:
so, I would do more data tests since ATT now has 4g in my area but they have officially started data throttleing me.... my fastest speed was .15mbps compaired to 7.0mbps non throttled... I kno 5% of users may seem like small fish in a rele big pond but imm pretty shure were phranahs and I hope we bite ATTs hand off cause of this rediciolus throttleing...
[HTC Inspire 4G] shugga101:
So is this why I can't go over 1mb download anymore? Because AT&T has been throttling me without notice. WTH if only Sprint got good coverage where I'm at. Shoot i'd settle for Verizon.
[HTC Inspire 4G] MarkF001:
Yes. and no. It's not specifically that AT&T has been throttling you. But, they do throttle most congested markets to 1Mb now, rather than the 1.5Mb, the same areas were capable of, not long ago.

The throttling he is talking about, is a full speed data cap; like T-Mobile does. Go over a certain amount, even on your grandfatherred unlimited plan, and they will slow you way down.
[HTC Inspire 4G] BereanPK:
Isn't it also possible that the cell system is like DSL, where the more subscribers using the system at any one time, the slower the speed?

I live outside the Pittsburgh area, where 4G is supposed to be, and I get average d/l speeds in the 4-5 MB range, but I work in the Oakland area, where University of Pittsburgh is, (and about 18 billion iPhone users, no doubt) and with 4G, my average d/l speeds are in the 0.75-1.5 range.

Am I right in thinking that the number of users actively using data services at any given moment will drag everyone's speeds?

[HTC Inspire 4G] gregsarg:

I'm anxious to adjust and test these values also ..

(Thank you button pushed )......g
[HTC Inspire 4G] Pick_A_Name:
Exactly right. At& t's Internet pipe is limited to the frequencies they have. Only so much data can be sent on those frequencies. The more people using the frequency the less each person gets. Usually at night you can get better speed on cellular networks because most people are at home.

I was one of the 5% . the data speed slow down , i actually called . the lady told the cap is 2 GB after they put the breaks in the pedal. she even told there was a survey for that, that is the average.

but now with the new settings i get a full MB which is may better than before crappy 334 kbps.that was the down speed the up speed was 156 kbps. i have to see when the speed get back to normal march 4 to see the new speed . but this is pretty good .

[HTC Inspire 4G] homeslice976:
Yes, some chefs edit build.prop in their ROMs, so values are changed from stock already.

And you can set your network to only connect to GSM, which gives me better signal most places, but only Edge data. You can do this by entering the phone's hidden menu (Dial *#*#4636#*#*), go to Phone Information, then change "Set Preferred Network Type" to GSM only. Some custom ROMs will allow you to change this in Settings -- Wireless and Networks -- Mobile Networks. Sorry if that's not at all what you're looking for
[HTC Inspire 4G] s1ickwi11y:
I tried doing this exact same thing on Atrix, and it kept reverting back to H+. Now, my Inspire's doing the same thing. It switches to Edge for a moment, but after a minute or two it changes back...even though I've chosen "GSM Only".

Thoughts? There are a few places on my commute that this could help tremendously on.
[HTC Inspire 4G] dacket84:
Mine seems to ignore the settings as well. Except when I switch it to EvDo only, then it actually gets no signal at all. (expected)

I have a question in regards to this build prop editing.

I am using Tmobile on the inspire unlocked with edge speed.

Ya I know its a waist .. but I figured that the mod might even help edge speeds slightly in its own way?

Or is this for 4g data only.

Fruits of my curiosities...and ~ALOT of reading...

led me to try the settings you see below. The "hsdpa=28" setting is actually a future 4G bandwidth setting....that also seems to work somewhat - right now!

These same settings have been used in ~EVERY INSPIRE ROM~ listed on xda....yes, I tried them all!...They are all VERY fine works of some extremely talented people...in my humble opinion.

ro.ril.enable dtm=1 (dual transfer mode for ATT "you know, the talk & surf at the same time" thingy)

ro.ril.gprsclass=12

ro.ril.hsdpa.catagory=28

ro.ril.hsupa.catagory=6 or 7 (with hsdpa set at 28 it doesn't seem to care)

ro.ril.hsxpa=3

reboot twice...that seems to be the norm for these settings changes to reach an operational state.

I live in West Texas..."da sticks"...."bfe"...I promise you, there are no towers up the street from me!...and these allow me a pretty consistent 3000kbps dwn / 1400 - 1900 up

gprsclass above 12 seems to revert back to a lower default, same with hsupa - 6 "IS" the actual protocall setting - 7 seems to push and revert lower at times...I opted to leave mine at 6

try it out, it sure worked for me.
[HTC Inspire 4G] substance12:
Where did you get the 28?

update1: woah, definitely increased download by 800 ish kbps by changing hsdpa to 14

update2: i may have spoken too soon. i didn't save the build.prop file so it was a fluke. I'm currently testing it at 14 but since it's raining the speedtests are a bit sporadic.

[HTC Inspire 4G] rickf2usa:
While combing thru numerous "I've got the magic pill for this" links, trying to get my Inspire to a respectable data rate (ugh)...I wound up at Wikki pages, sifting thru At&T engineering pages that covered

ALL

data packet tranfer protocols all the way up thru upcomming LTE, which BTW....that 28 goes up thru a setting of 32!! The 28 is the upper limit setting for the HSXPA+ packet rate categories that matches up to the hsxpa=3 protocol setting we're all attempting to use. That's as simple as I can lay that out...without subjecting you to the "extreme morosity" I went thru to find it...about 2 full cups of coffee later!!!

**For future reference...that setting will net you approx 42000kbps, once AT&T rolls out the real deal - the "second full layer" to 4G, the backhaul sidebanding neccessary to achieve it. Then LTE after that...that stuff is off-the-charts!...we won't be measuring our outputs by kbps anymore, but then...we won't be complaining either.

[HTC Inspire 4G] bella92108:
No these threads won't. You don't get it, do you? Nobody is ever going to be impressed by old technology. Right now, AT&T is STILL working on delivering 3G to some fairly sizable areas in the network.

By the time AT&T actually goes live with 4G via LTE, the other carriers will be on 5G, so 4G will just be "it's about time" lol

anyone seen this link

http://en.wikipedia.org/wiki/High-S...cess#HSDPA_User_Equipment_.28UE.29_categories

it says the hsdpa category for HSPA+ starts at category 13. I don't know what the default config is but i've seen 10 on a lot of roms. category 10 has 14.4 mbps and I recall seeing that number floating around but it's classified as HSDPA. what am I missing here?

switching from 10 to 14 also changes the QAM from 16 to 64. I'm have no clue about the actual effects of that occurring.

I just got a postcard from AT&T advertising upgraded 3G service for the New York Metro Area. Good thing I already have "4G".

[HTC Inspire 4G] dmacrye:
So based on this info our Inspire's theoretically are only capable of category 20 since AT&T hasn't deployed Dual-Cell HSPA according to the linked page.

According to this we should set the HSDPA Category to 20 instead of 10. And according to this: http://en.wikipedia.org/wiki/High-Speed_Uplink_Packet_Access HSUPA should be set to Category 9 to engage maximum speeds.

Am I incorrect in thinking this way? Anyone care to disagree?
