almost home from work and will try the KD1 first and see what speeds I get.

I do get the H with the current KE1 modem but the upload still mot over .40 and download has gotten max 2.01.
[Nexus S Android Development] pdxrealtor:
I just got back from running errands around town all the while doing speed tests around town :D

I even swapped build.props and radios.

The best combo for me in Portland OR. is the KB3 radio with the tweaked build.prop

Bursts of up to 3.5 Mbps that would settle down to 2-2.5 Mbps down and consistently 1 - 1.5 Mbps up. This was best case.

Worst case was below 1 Mbps down and less than .50 up.

I actually stopped into a corp. ATT store since I had to port a number over. It was busy so I decide to download the speedtest app on an Infuse and a Captivate (Infuse is 4g, Captivate is 3G)

The data was horrible on their phones. The Inspire topped out at 3 Mbps, never saw a 4 Mbps out of 5 tests. The Captivate topped out around .50 Mbps. Both phones were very jumpy.

My phone, standing next to the infuse, was pulling 1.2 - 1.4 Mbps down and doing the same on the other side of the store standing next to the Captivate. My phone had had the KB3 radio in the ATT store.
[Nexus S Android Development] pdxrealtor:
I agree... must be the location. I did verify it wasn't just the icon, that icon did actually represent the actual radio mode.

Coming from Tmobile 4G this is a definite slow down, however it is also much more consistent in terms of voice and data coverage.

I would miss a bunch of calls if my Tmobile was not on WI-FI calling, never happens on ATT (I've was with ATT for 6 years before my recent break to Tmobile)

Again... location specific.
[Nexus S Android Development] ElCamino:
That seems to be great speeds considering the Nexus S is not like the Infuse the so called 4G. :-) I will try the KB3 radio but can you post your settings you are using for build.props. thanks.
[Nexus S Android Development] pdxrealtor:
Ya...I'm pretty happy with the speed now that I got A chance to test it out.

Here are the build.prop settings I used;

ro.ril.enable.dtm=1

ro.ril.gprsclass=12

ro.ril.enable.3g.prefix=1

ro.ril.hep=1

ro.ril.hsdpa.category=28

ro.ril.hsupa.category=9

ro.ril.hsxpa=2
[Nexus S Android Development] ElCamino:
Thanks pdarealtor, now I have been testing the KB3 and getting great results. Average 180 ping 2.5 download and .85 upload. I will test without changing files till tomorrow and then add your settings. Looks like I will be keeping this radio KB3 for now. I'm getting H+ speeds :-) according to what AT&T considers 4G.
[Nexus S Android Development] ElCamino:
By the way I see you also have the Galaxy Tab 10.1 tablet? Good choice. :-) I got mine at Best Buy then two weeks ago Staples had the $100 off tablets so returned back to Best Buy and purchased at Staples. Best Buy didn't want to match discount.
[Nexus S Android Development] ~Reaper~:
hi all I just came from my captivate to the nexus s on att I love the phone so far but i would like to enable the hsupa but have no idea where to begin

i assume i have to root first duh!! which is no big deal but where do i go from there

I really do not want to run a custom rom as the phone works great out of the box and from reading i don't think i have to is that correct.

and which radio do I flash ? I live in the chicago area

any help would be appreciated

sorry for the noob ????
[Nexus S Android Development] ~Reaper~:
i must of missed this

will this work instead of flashing

1, Open "Root Explorer" and mount R/W.

2, Go to "system" and you will find there is a file name "build.prop".

3, Right click (By holding at the file) and there is menu pop out.

4, Scroll down and select edit in Text Editor.

5, Type in those few line of words below into the last line of the text.

ro.ril.hsxpa=2

ro.ril.gprsclass=12

ro.ril.hsdpa.category=14

ro.ril.hsupa.category=6

6, Save the file and reboot your phone TWICE.
[Nexus S Android Development] ~Reaper~:
i was just looking through my phone status and it say's

mobile network type HSPDA

does that mean i am already good to go ?

i am so confused

lmao
[Nexus S Android Development] window7:
Yes, this will work for the HSPDA tweak :)

And for which radio, I guess, KD1 is the best so far :p
[Nexus S Android Development] window7:
That's good you have HSPDA, this tweak is to enable you have more "agressive" HSPDA :)
[Nexus S Android Development] ~Reaper~:
ok so I really do not need to flash the radio as I have it already

but i can use the tweak to speed it up a bit

do I need to be rooted?
[Nexus S Android Development] window7:
Yes, you need to use root explorer :)

For root explorer, you need to be rooted :p
[Nexus S Android Development] ElCamino:
I have rooted and running CM7 nightly but yeah don't have to install custom ROM to install the radio.

Like Window 7 says you have to be rooted at least. Im on AT&T and yesterday tried both the radios KD1 and KB3 has been better for me. KB3 stays on HSDPA more for me then KD1. Also getting -91db with 5 to 7 asu. I don't have signal around my house so will test out later some more.

Also with KB3 radio my data speed is much higher at average of 2.8 download and. 80 upload. This is without changing anything on the build.prop file, which I will do today.
[Nexus S Android Development] ElCamino:
Here is this morning test I did on my Nexus S on AT&T.
[Nexus S Android Development] xLiljohnCx:
Need help getting my 3g back! I tried both methods but none work method 1 didn't do anything and method 2 gave me 3g but the imei is messed up! So I restored the /efs now I'm back to edge! -_____-
[Nexus S Android Development] ElCamino:
Check a few post back but if j remember someone saying to switch to wcmda or something by going to *#*#4636#*#* then turn off the radio within there. Then go and replace your EFS files. Then reboot.
[Nexus S Android Development] ElCamino:
I think battery drain is much more with KB3 radio running with H icon. Went from 98% down to 80% in 3 1/2 hours. Yesterday before changing radio using stock KE1 I went from 97% to 85% in about 4 1/2 hours.

I will still test as maybe the KB3 radio keeps the higher speed which I believe uses more power? Anyone?
[Nexus S Android Development] tkgod:
Actually I thought KD1 had more drain. I suppose higher speeds would likely drain the battery more. Just look at our first gen LTE phones.
[Nexus S Android Development] ElCamino:
Yeah i agree LTE is power thirsty. :-)

Seems that when i had KD1 it also would make my search button go off quite often so installed KB3 and actually has stopped or at least the search button has only gone off once since yesterday.
[Nexus S Android Development] tkgod:
I don't have search buttons issues, but my back button will intermittently become difficult to use or not function regardless of kernel. I'm really considering going back to HTC because even in spite of touch screen issues, I really loved my nexus one and HTC makes some very beautiful phones.
[Nexus S Android Development] window7:
It's not about the phone manufacturer. I think most of us has a very great responses for the back button. Probably you're one of the lucky person who get a phone with back button less functioning.

Try changing the digitalizer :)
[Nexus S Android Development] nonameduck:
I have a i9020a Nexus S with I9020AUCKB2 radio, and it looks like I have an upload limit of 40KB/s. What radio do you guys recommend?
[Nexus S Android Development] melvinchng:
Do you mean 'HSDPA'?
[Nexus S Android Development] melvinchng:
Which radio saved the most battery for i9023? I don't care about speed... my phone is in 3G connection... I put my broadband sim card here..
[Nexus S Android Development] window7:
There is not battery saving radio :) Just the difference of radio in terms of signal strength.

But then, I would suggest you to use KD1 as most of the people are using KD1 :p
[Nexus S Android Development] melvinchng:
I'm using KD1, my house has super low 3G, always use up a lot of battery.
[Nexus S Android Development] window7:
Malaysia has very low 3G signal. I admit that as I was from Malaysia too. I am in Australia now for studies.

Try KB3 then :) Maybe will be better?
[Nexus S Android Development] melvinchng:
I'm using maxis... widest 3G coverage... house don't have good 3G... but outside my house has...
[Nexus S Android Development] ElCamino:
If you have low signal, that will always drain the better as your phone is always trying to connect to cell towers so it will ue more baterry. I'm using KD3 on AT&T and also used KD1, but KD3 gives the higher speeds and stays on HSDPA 99% of the time. With KD1 it would go back and forth between HSDPA and UMTS.
[Nexus S Android Development] dario3040:
At least in Norway there is a lot of 3G coverage.

I always have 5 bars of 3G.
[Nexus S Android Development] tkgod:
Err...is that possible? I'm assuming you're meaning software right?
[Nexus S Android Development] melvinchng:
I set always on HSDPA only..

0 bar 3g, 2 hour 45 minute screen on, ebuddy xms-ing, from 90 to 23% battery left...

So which radio to use? I'm on i9023.

I will backup my phone IMEI first and flash radio tomorrow... any more things I have to notice?
[Nexus S Android Development] ElCamino:
I finally edited my build.prop files and don't see any difference in speed or anything. Still same as before. I'm using KB3 radio. I rebooted twice like instructions said. I also put the files at the end. Will leave files and continue to test. More likely will remove file.
[Nexus S Android Development] window7:
Digitalizer is the circuit board that connect your phone chip to the capacitative button :p
[Nexus S Android Development] window7:
Back up your EFS file, not the IMEI. Haha. Then, flash the radio. There is none of the radio will cause EFS file problem except the UCKE1 that I had removed, so no worries :)

Try different combination like what simms22 said.

ro.ril.hsxpa=1

ro.ril.gprsclass=10
[Nexus S Android Development] tkgod:
So what you're really saying is get a new phone... Going through all that trouble wouldn't be worth it.
[Nexus S Android Development] window7:
If you still have your warranty, then ask for a change. If not, then I am very sorry about that :(
[Nexus S Android Development] tkgod:
I lost my receipt or I would have sent it in for the imei issue.
[Nexus S Android Development] Southrice:
I wish I had 3g :(
[Nexus S Android Development] melvinchng:
Work very well... will try my battery one day... maybe it save more... who know?

Thanks!
[Nexus S Android Development] ElCamino:
Ok thanks will give that a try. :-) so far liking my uncapped AT&T speeds.
[Nexus S Android Development] window7:
I changed the setting a bit for the HSDPA tweak, maybe you would like to give it a shot? :)
[Nexus S Android Development] ElCamino:
What was the difference between not changing the file and after adding the tweaks?
[Nexus S Android Development] melvinchng:
KB3 doesn't works perfectly... my country has more 3G than Hsdpa... when I go to the place with 3g, the h changed to edge and not 3g... I set wcdma only...
[Nexus S Android Development] window7:
Hmmm.. I think this will able to answer your question :p
[Nexus S Android Development] window7:
I need those who are using UCKE1 radio (Original radio is UCKE1, not after flashing it) to extract the radio once again please. Thank you :)

HERE'S how you extract it :)

But not for california, would you like to test it for me? :p
[Nexus S Android Development] Dazog:
I am from Canada on Rogers I did a ton of speed tests in the same spot on both radio's.

The KD1 is an ATT radio since the 9020a phones are ATT verisons.

They cap there uploads on there network right now.

My phone does 2-3 upload with KB3 and like .80 with KD1.

[Nexus S Android Development] tankmaster90:
yea i'd be down to test it for you. But how would i go about that, signals are never perfectly consistent.
[Nexus S Android Development] Ok_Kaleidoscope5109:
I tested KD1 heavily too and it wasnt upload capped for me on AT&T. I was getting 1-2mbit uploads on both KD1 and KB3. Indistinguishable.

The KD1 I used was BEFORE the KD1 update came out for the 9020a. Is this KD1 from the 9020a? That might be the difference.

The KD1 I used was pulled from the 9020T. Maybe that's why? Maybe all the radios for the 9020A are capped...
[Nexus S Android Development] Dazog:
I tried the KD1 from the 9020T release, I didn't know the KD1 for 9020a is different?

Did you do a checksum to see if they were?
[Nexus S Android Development] entropy1980:
I have downloaded it on 3 different computers from the link on first page, recopied and I still get the error. What am I missing?

Here's what I have and what I am doing:

9020A running 2.3.4 Build GRJ22

Baseband I9020AUCKD1

I am doing the following:

- With the phone off, holding the volume up and powering on

- Selecting "Recovery"

- Get yellow exclamation and Android dude

- Press power and the volume up a couple times to get into "Android system recovery"

- Select apply update from /sdcard

- Select "Radio Nexus S [XXKB3].zip

Get the "E:signature verification failed" error.

Any suggestions?
[Nexus S Android Development] Ok_Kaleidoscope5109:
i9020a users please report:

When you switch to 2G only and then switch back to 2G/3G using either KB3 or KD1, does your phone let you go back to 3G? Seems like I can't get back to 3G.

I flash the stock KB2 radio and then a KB3/KD1 again to get back. Seems like the KB3 and KD1 radios are designed for euro frequencies and don't play well with 2G/3G switching on 850/1900.
[Nexus S Android Development] steve.garon:
window7,

For the sake of choice, you can add my UCKD1 radio from my signature to the OP. Its upload capped but on my i9020a its been the most stable choice of radio yet.

The flashable zip was made by extracting the radio from the official GRJ22 update to the i9020a.

I just thought I'd share with the rest of the world :P

Steve
[Nexus S Android Development] mr_raider:
Type *#*#info#*#* in the phone dialpad. Select phone info. Press menu button. Select band > USA
[Nexus S Android Development] mr_raider:
In what way is it more stable?
[Nexus S Android Development] steve.garon:
I've notice the following on my phone (i9020a).

Pros:

- Better signal in poor reception areas

- More consistent download speed (maybe related to the better reception...)

- Faster to pick up 3G signal when turning on/off data and airplane mode

Con:

- Capped at 40KB/s upload (But I don't care, when I upload stuff I'm on wifi anyway...)

Cincinnati Bell

Hey all,

So I've seen that the regional carrier (Cincinnati Bell) is now offering the Nexus S. I was wondering if anyone has actually purchased the Nexus S from Bell or if anyone has a system dump from that carrier. I've always had problems such as "writing" call settings for Call forwarding with my Tmobile Unlocked Nexus S running on Cincinnati Bell's Network. I've always attributed this to the Radio and thinking the Radio was made specifically for the major carriers. Does anyone care to enlighten me or better yet does anyone have the radio from this regional carrier?

Thanks!

[Nexus S Android Development] rentaric:
What does it say in the first post? UCKD1 = i9020a only
[Nexus S Android Development] daffyno:
I read that some people have been beneficial in Malaysia using uckd1 on 9020t (for low 3g coverage).

they had problems only with ucke1 (and 9020t), but i would use only uckd1

anyone can confirm?
[Nexus S Android Development] ykphuah:
I am from Malaysia, and I have tried UCKD1 on I9020T, results were inconclusive, sometimes I failed to get connected to GPRS/EDGE where previously I could. I have since then switched back to KD1, and seems like there's no permanent damage to my phone for flashing an "incompatible" radio.

Not sure about UCKE1 though.
[Nexus S Android Development] JuliusCes:
Hello,

Can someone please take the time to explain these basebands? I am currently on 2.3.4 GRJ22 9020AUCKD1 and I live in Morocco, which uses the same frequencies as France. Am I on the right baseband? I notice that it usually takes a long time for my nexus s to find 3g signals. At least much more time than my previous Samsung galaxy fit phone.

Thanks for your responses.

[Nexus S Android Development] rentaric:
If you weren't on the right radio version you'd have no mobile internet and phone signal.

What you can do is take older radios for your device and try them if they offer better reception then KD1 in your region.

In case anyone was on the fence after the fiasco involving the previous UCKE1 radio that was in this thread...

I went ahead and tried the new & corrected UCKE1 radio on the first page and everything looks normal here on my 9020A. 3G working as expected. Seems a little more "responsive" in terms of deciding when to use edge or UMTS vs the KB3 radio for me. More like the KD1 radio (only problem with KD1 for me was it would constantly activate my search button in low signal/change from H to 3G situations).
