Not sure why people say KD1 is best for Australia, I'm in the Illawarra/Canberra and the KI1 works perfect (it was the stock BB when I got the phone) and KD1 seems slow and intermittent.

Anybody else compared KD1 with KI1 in Aus?

Just going to put this out. I'm using the 9020a Fido, with Cyber ROM Speedy 7 Kernel. I would like a good radio with 3g, not caring about H because I don't believe Fido has that going yet, could be wrong.
[Nexus S Android Development] floydlloyd:
Glad you asked this. I'm in the same boat i9020a on Fido Matrix kernel V3.5 and Stock ICS 4,03

Current radio uckd1 I've tried the ones here in this post but only this one seems reliable.

Any wisdom out there to achieve better speeds on FIDO (mostly concerned with upload speed)

Either new radio or specific tweaks

How do you remove the tweak it's giving me abysmal service in some places where it continuously switches back and forth between umts3 and hspda9 and is slower than edge.

Once again I have to ask. Is it bad my radio constantly switches between 3g and H speeds? I'm not sure Fido is equipped for H speeds but I imagine that does a weird battery drain on it? How can I get it to remain as one connectivity vs flipping
[Nexus S Android Development] caliban2:
I always wondered why Android normally just shows 3G in the status bar - I'm beginning to see why...

It took me 10 seconds to look your provider up on wiki. Yes, it does provide hsdpa. Wonders of the internet...

3g and hspa are the same network, also known as umts, hspa just being an extension for faster data. 3g reaches 384 kbit/s Max, whereas hsdpa normally tops at 7.2 mbit/s. (Hspa+ goes even beyond that, but that's not the point here)

Standard behaviour is to use 3g when doing nothing or during phone calls, while hsdpa is only used when data is received. So, normal behaviour you're getting.

Some providers break that standard and will always show you the H - cosmetics.

If you want to save battery, switch to 2g only. There's nothing to gain from disabling hsdpa. (Same network as 3g, remember?)
[Nexus S Android Development] Paragon_X:
Thanks mate, the wonders of the inet truly put to use. Well, then I guess next step is awaiting 4.0.4 and the OS bug fix. Other than that I'll stop my flashing and remain with my radio, thank you for googling unlike my lazy ass.
[Nexus S Android Development] caliban2:
4.0.4 ported from nexus s 4g runs fine and it's better on battery. Also, next official update for us is 4.0.5 (french provider announced it coming to nexus s "in march"...) ;)
[Nexus S Android Development] Ok_Kaleidoscope5109:
Uh but if you go to Settings => About Phone => Status there's a different status for Mobile Network Type when it says UMTS or HSDPA.

I believe there IS a difference between UMTS and HSDPA. Most providers will stay on HSDPA in my experience. I've traveled across the US and to many countries on my Nexus S and it always shows H. SOME radios will default to 3G for some odd reason and fail to connect to HSDPA. It's a pretty big speed difference.
[Nexus S Android Development] caliban2:
You believe?

Please at least try to get your facts straight before spreading false believes... ^^

Lost Connexion HSDPA

After several flash rom and radio for ICS .. tired of the instability of my Nexus S I9023 Gsm .. this morning I restored the original gingerbread through a file taken from this forum .. but I realized that the radio and the baseband is different than when I bought the phone. Since I lost my HSDPA connection .. now does not go beyond 3G .. I install the radio XXKB1 ..IML74K.. as it was originally on the radio? Currently I XXKF1 Build Number GRK39F ..

Radio Question

Sorry if this is kind of a stupid question guys, but I ahve the 19020T version of the Nexus S, just wanted to verify. the most recent/stable radio for it would be the KF1 correct?
[Nexus S Android Development] caliban2:
Why, what's wrong with KI1? :confused:
[Nexus S Android Development] mahanddeem:
I never saw "H" symble on my Nexus S ... Not in GB nor in ICS !!!! not even in the user manual !

what's "H" ?
[Nexus S Android Development] caliban2:
relax, you're not missing out on something. don't let yourself be fooled by the believes of someone... H stands for HSPA -> Wiki. As i wrote earlier it's a data-protocol for the 3G/UMTS-network. But it's not some special sort of hack or secret mod to get faster speed.

Android always shows 3G, unless you have a modified SystemUI.apk (aka "hspa-fix"). then it will show 3G while nothing data-related is happening and H when data is transferred. That's how it is specified in the technical standard (only use HSPA-channels when needed).

to make things a bit more complicated, some providers have set their network up to always let your phone show the H-symbol. technically, that's a violation of the standard, but no harm - no foul. it's just makeup.

on an unmodified system, you can check in settings -> about phone -> status:

there it will show umts:3 (3G) or umts:9 (H), depending on what's going on...
[Nexus S Android Development] Klash6543:
nah, i'm not saying anything is wrong just, that i'm on simple mobile now, and my 3g speeds arent that great so i was wondering if its becuase i never updated radio after coming from CM7.
[Nexus S Android Development] ShadowVlican:
My phone is always switching between 3g and hspa.. And it's annoying because I only have data when it's showing hspa..

Yes.. I can see my data stop working whenever I see 3g while I browse the internet.. Cuts on and off

I have a feeling this is because my preferred network is gsm/cdma auto... It should be wcdma preferred, but that setting doesn't stick..

what's the best radio for a 9023 on Italian networks?
[Nexus S Android Development] Ok_Kaleidoscope5109:
the "new version" for UCKF1 for 9020a doesn't give me 3G at all. Is this what people are experiencing or is it just me?

Furthermore, I believe the OP should edit the KF1 under the "Radio for I9020a/I9020t/I9023" section and say that it doesn't work for 9020A either. Both KF1 and KI1 don't work for 9020As.
[Nexus S Android Development] benniebeeker:
im curious about this myself... i have an i9020t (says under the battery) or i9020xxjk8 (in about) radio and flashed to jk8... the speeds marginally increased... not sure if i should try flashing to:

Radio Patch for I9020T ONLY

Radio KD1 =>> KF1

in chicago by the way....
[Nexus S Android Development] litanyoffail:
I don't know what I'm doing wrong here...

I started with UCKE1.

I flashed XXKB3, and it worked for a few speedtests.

I flashed UCKF1 (new version); also worked for a few tests.

Flashed back to XXKB3, still worked.

So I reboot my phone to create a backup, and when the phone's done booting, I don't have any service (No voice or data connection).

I tried the 3G fix, no luck. Read somewhere that flashing the stock radio fixes it. So I flash UCKE1, and my service is back.

Now, if I try and flash anything, I lose service, and flashing back to UCKE1 brings it back.

I'd really like to use XXKB3, because speeds were ridiculous for the two times i was able to run tests. Any ideas?
[Nexus S Android Development] benniebeeker:
forgive me for being such a noob here but i can't seem to find the information that i'm looking for... i own a nexus s 3g... the model on the sticker under the battery reads gt-T9020T... when i check settings/about phone/baseband version, i see I9020XXJK8... from what i gathered by reading this thread, the baseband version is nothing more than the radio flash currently in use... i'm assuming its okay to experiment with different flashes as long as i use one that is appropriate for my phone model...

on the first post of this thread, i read what i lined below and assumed that the ONLY radio i was to flash was the one in bold...

Radio for I9020a/I9020t/I9023

Radio JK1/Radio JK8

Radio KB1

Radio KB3

Radio KD1

Radio KF1

Radio KI1 <<= I9020a DO NOT FLASH!

I'm assuming that i can flash ANY radio listed above since my phone is the i9020t???

would it be safe for me to flash the following???

Radio Patch for I9020T ONLY

Radio KD1 =>> KF1
[Nexus S Android Development] caliban2:
No, you can flash any radio from that list you posted, not just the bold one. They're oldest to newest from top to bottom. (KI1 came with ICS)

About the patch:

Nope, that's just an incremental update from kd1 to kf1 only.

HSPA Tweak 1st

Greetings All,

I'm not so noob, but I am still a reluctant Nexus S root user.

I rooted my phone yesterday and installed CM9.0.0-RC0-NS.

I have the KI1 kernel and am having trouble connecting to 3G. When I try to search a website it take forever to load and when I try to send an email/tweet/text it takes a long time to send.

I did a HSPA tweak today because of these issues. Can I work backwards and flash my radio/kernel after doing the HSPA tweak?
[Nexus S Android Development] sean1984:
just flash your rom again
[Nexus S Android Development] benniebeeker:
ki1 isn't a kernel, its a radio flash... try a different radio flash... ;)
[Nexus S Android Development] jonhdoe1000:
Can i flash any radio to the ICS build?

Does the HSPA tweak work also for the most updated radio (KI1)?

Is the radio also effects the poor reception and speeds i get for wifi?
[Nexus S Android Development] xda<3:
Ok so my understanding of this is that I can flash any radio on this post compatible with a canadian (fido) nexus s (i9020a) on any custom rom... Am I correct?
[Nexus S Android Development] mahanddeem:
you can flash any radio after any rom (if compatabile with your phone)
[Nexus S Android Development] jonhdoe1000:
does the radio also impact the wifi performs? or wifi signal strength?

regarding the hspa tweak:

if my phone under settings/about phone/status/mobile network type indicates 9 (hspa) then do i still need to use the tweak in order to take advantage of the network capability or it means that it is already configured for that?

thanks
[Nexus S Android Development] litanyoffail:
Alright, I'm at a loss here.

I'm not a noob, but this has me scratching my head here. I've done everything short of ODIN flashing this damn thing.

Any radio I flash makes me lose service, except UCKE1. No amount of moving/backing up/deleting stuff in the efs folder restores service. Flashed using methods 1 and 2, method two only working with signed radio images. Using the *#*#4636#*#* steps yields no (positive) results. I've even done clean ROM installs, also nothing.

Is there something exceedingly simple I'm missing here?
[Nexus S Android Development] theadb:

[Nexus S Android Development] litanyoffail:
Update on my own issue here: after completely deleting my efs folder, I lost my smsc. still no luck with other radios. Fixed the smsc, and flashed KB3, and it's miraculously working. I get decent speeds for about a minute, then it got erratic. Rebooted phone, and I get no service again.

Baseband read NO DGSXXKB3 before and after service loss. Back on UCKE1, it says I9020AUCKE1... Whaaaat is going on :confused:
[Nexus S Android Development] Andrew1998:
What is the better for Nexus s i9023 italian 3g GSM with ibox.tim.it?
[Nexus S Android Development] ChargingPaladin:
Radio revert is odd. It should read I9020XXKB3 when on KB3. Are you using fastboot or just flashing through recovery? Should be using fastboot, flash and reboot bootloader, see if the right baseband is listed at top in bootloader immediately after flashing radio.

I get the exact same thing regardless of flashing through recovery or through fastboot. Fastboot does show the radio I flashed correctly but in about phone I get the NO DGSXXKB3 unless I flash the capped radios. Again, i9020a on ICS. I tried flashing the radio in GB and got the same thing. One more thing, I updated my bootloader to the new KL1 rather than the original KA3.

Is it OK(and better) if I flash KB3 radio on my Nexus S I9020T stock ICS on t mobile ? is it better than the stock ICS radio KI1 ?

thanks
[Nexus S Android Development] .:Crack:.:
Hey,

is there any performance difference between UCKF1 and XXKF1 (especially for my country - Germany)? Or is it just a device compatiblity thing (-> different GSM frequencies used)? And why shouldn't i9020a users flash XXKI1?

Edit:

My i9000 supports:

GSM/EDGE : 850Mhz - 900Mhz - 1800Mhz - 1900Mhz

WCDMA/3G : 850Mhz - 900Mhz - 1900Mhz - 2100Mhz

And my carrier uses 1900mhz for uplink and 2100 for downlink (I think - see "EPLUS" here)
[Nexus S Android Development] .:Crack:.:
Another question:

UCKF1, XXKB3 and XXKD1 work perfectly fine on my i9000 but XXKF1 and XXKI1 don't. What could be the reason? (especially concerning both KF1's)

Thanks in advance guys!
[Nexus S Android Development] caliban2:
You don't make a lot of sense... you keep writing "i9000", but that's the galaxy s! Nexus s is i9020/i9023... what do you have?! Never, ever cross flash, especially not radio!!! (And boot loader)

That said, IF you have a nexus s, in Germany it will be the 9023 (slcd-screen). So the xx-radios are for you, all others are either capped (limited in speed) or for another model/frequency. Again, don't cross flash!

KI1 is the latest, and so far it's the best for me here in Austria, no problems in Germany as well. This means reception quality and battery drain. (In general, better reception means higher drain - it's always a tradeoff)

So if you're really unhappy, try one of the older xx-radios, but monitor batt-drain and don't expect any wonders (like making gold out of **** etc).

Oh, and if you're downloading stuff:

I9020T = I9023 (same phone, just different display; don't have to care, use it)

Everything else = not for you! (9020A, D720...)
[Nexus S Android Development] .:Crack:.:
Thanks for the insight but in fact I'm talking about Galaxy S i9000 running ICS 4.0.3 (MTD).

There's some testing with i902x radios/modems on i9000 running on MTD.

UCKF1 works perfectly and XXKD1 and XXKB3 work if you flash them over UCKF1 (otherwise there's no signal)... I'm testing KD1 atm, seems quite solid. XXKF1 and XXKI1 do not work (why? :O).

Well how can cross flashing harm in this case (-> I know crossflashing Bootloaders and stuff is the worst thing one can do. [not a noob :P]) since the hardware is very similar and the software (AOKP M4 Android 4.0.3) is quite the same.

Thanks again ;)

Edit:

So for now just UCKF1, XXKB3 and XXKD1 are working. Which of these is the "best", i.e. signal strength and call quality, for the Nexus S (I assume it will be best for i9000, too) in Europe/Germany?

Another Thanks !

So does anybody have an idea why XXKF1 and XXKI1 don't work, i.e. is there a known problem + fix for the Nexus S?
[Nexus S Android Development] ChargingPaladin:
Well, there does happen to be a search function on this very forum, but to answer your question(s): No,there is no specific trending issue with either of those radios. In fact, none of your previous questions will have a specific answer; radio performance is exceptionally case-specific, i.e., it differs by carrier, hardware model, hardware revision, ROM + kernel version, cell site specifics like capacity, distance, etc etc etc. The answer to every single question is ultimately "whatever is best for you" and that's what it's always going to be regardless of how many times you ask.

More importantly, this is STILL the Nexus S forum and since you're on the i9000 everything I just said stands double. I respect the ambition, really I do, and I'm a little jealous that you have that kind of hardware flexibility, but seriously.

Yeah, I should have made clear that I'm searching reviews by Germans or Austrians in order to get some halfway representative answers :P

Haha :P Actually I don't quite understand why 2G works since people over there stated SGS and GNS have the same 3G chip but not the same 2G chip...

So I did get (by reading :O) that UC*** have capped upload speeds but I did not find definite numbers, i.e. to which speed. Could you provide these?

Lol, if they have one thing in common it's the 2g-chip (heard of quadband?). Difference is in 3g-bands...

Anyhoo, since you're in Germany, the xx-radios will be best for you. Everything else is either capped or uses different freqs on 3g.

No, there are no problems with the nexus s-radios in Europe. Bootloader probably is the reason why the later versions don't work for you. There's a list on google-support which versions of the two correspond best. (Don't think you're going to try flashing bootloader...)
