Froyo - no HSDPA - Desire Q&A, Help & Troubleshooting

I have an HTC Desire.
When I install any Froyo-ROM (I am currently running Modaco r20, based on frf85b) i lose my HSDPA, and I can only run 3g.
Can anyone help me activate HSDPA in Froyo?

I believe that FroYo does not show the H symbol, even though you may have H speeds. To check, go into your settings and Status. Look under Mobile Network Type.

T-Mobile HSDPA

I just purchased T-Mobile's version of the Touch Pro 2 about a week ago. I moved from AT&T and the TyTN II.
On the TyTN II, whenever I was on HSDPA, the connection icon would display an H. On my Touch Pro 2, I only ever see a "3G" icon. However, my connection settings are set to use HSDPA/HSUPA. I have unlimited web service, for what's it's worth.
Is this normal? Am I in fact getting HSDPA service? If not, is it a registry fix? Is there anyway to check for sure what protocol I'm connected with?
I would like to know that as well, Its normal same thing on my tmo tp2
I see the "H" symbol, but only when actively downloading data. It switches back and forth which I think is a good thing. No problems on this end running the stock T-Mo ROM
yeah I kept getting the 3G icon too, but after i put on tsowen's taskbar, now I get the H & i don't think i've seen the 3G at all.

I have only seen the H icon after installing a custom taskbar as well. I'm not sure if it just replaced the 3G icon right out or if it is correctly displaying it.
My g1 displayed 3g when i had the t-mobile firmware on it. When i put a different one, H or something was displayed. The tp2 i have is the same way. I put a different firmware on it and it went from 3g to H now. I am not using the t-mobile firmware but one of the 6.5 roms. I would bet t-mobile put the 3g icon on purpose.
H and 3G are the same thing on the phone. It just depends on what your ROM is setup to show it as.

they are not the same:
3G = 364 Kbps
HSDPA (3.5G) = 1.5-3 Mbps
i get at least 650kbps with 3G only icon. So i think im on the H

I was referring to the phone just showing 3G or H not the actual speeds.
I'm in the same boat as you guys. When I was on the stock ROM I only saw 3G with 2 bars and this was at my house. Now that I'm on a cooked ROM, I see H all the time with my 2 bars at my house. I only get the H when I'm at home, but when I'm at work I get 3G with full bars. I don't even have the option to use HSDPA checked, I have it unchecked in the options.
I'm sure the H has to do with the cooked ROMs or custom taskbars. Idk!

Is there any way to disable automatic switching between UMTS and HSDPA?

In my apartment my G2 constantly switches back and forth between UMTS (3G) and HSDPA (H). Is there any way to stop this? Both look like they have the same number of bars, but it seems like UMTS is way slower. I also should be in a 4G market, so is there a way to tell if I'm on HSPA+ or not?
I've honestly never even seen the 3g icon on my g2. whenever im in kent, when it drops it drops from h, to E

I don't think the stock G2 ROM has a specific icon for 3G, if that's what your'e on. It shows H for 3G/HSPA/HSPA+.
I think the original poster is on Cyanogen, where it does show the type of connection a bit more accurately.
I'd also be interested in trying to force an HSPA connection. I don't think Bell has UMTS data so if I'm labeled as on 3G I can make calls and texts but have to wait for it to switch to H when I start using data.
It's a feature of cyanogenmod that it switches to 3G when heavy data is not required and switches to H+ when you need a faster data connection
That is of course if your running CM on your phone...

It's not a "feature" of CyanogenMod. This also happens on the stock ROM but we do not see the H icon, only the 3G one. Cyanogen himself explained this a while back.

You mean stock sees only the H icon, not the 3G one XD
Also note that if you're not actively using data, it'll show the 3G symbol (on Cyanogen or Sense ROMs) - as soon as you start a connection, it'll switch to an H. This isn't necessarily because the phone is switching between a 3G and HSPA signal, but rather because 3G is also used to carry voice - so if the phone isn't using HSPA for data, it obviously doesn't need to show it.
Thanks for all of the information, guys!

[Q] No 3g Download, only HSDPA or EDGE

Various apps (Facebook, Market, Head to Head & Internet Browser) will only download data when there is a connection to the HSDPA signal.
The 3G signal has shown as 3 or 4 bars but will consistently not download any data. Once the HSDPA signal is found, then the download starts. This can be frustrating as there isnt always a HSDPA signal.
i tried to insert another network provider sim card and it showed 3G and when i tried to launch for example browser it instantly changed to HSDPA icon and loaded pages so i didnt check anything... (i couldnt recreate a situation when only 3g was available, no HSDPA)
I currently am on DHD by baadnewz 1.7b but this also happend on Stock Desire Froyo.
any advices ?

It's difficult to comment. If you're rooted, try another custom rom with an updated radio.
i have the newest radio

If the "3G" signe appears in your phone, this means that it's trying to connect to your carrier's network. Once you're identified your can start to use data connection, then you get "H" "E" or another depending on the technology used by your carrier.
H goes for HSDPA, E Edge and so on...
So the lagg time is when your carrier tries to search whether you've got acces to a data plan or not.

[Q] Does the GNex have H+?

I'm on the 3 UK network and my SGS2 would show H+ when I'm at work. The GNex only shows H. Is it actually connecting at H+ and not showing it? Does it show H+ differently?
Why don't you run a speedtest to see if you are getting HSPA+ speed? Previous Vanilla Android doesn't show the H symbol at all, just the 3G symbol.

It supports 21 MB HSDPA
so defo yes
Hmm, I'm on 3Uk as well, but speed test shows that I'm only getting 0.3~0.5mbps, even with the H symbol...
Is there something wrong with my settings?

most likely issues with your coverage area.
It has 21mbps HSPA+. Who cares what the status bar says?

The H+ icon is a result of Samsung adding their own icon.

It's true that stock builds usually just show it as 3G. It's just a single value you enable the option in AOSP though. It was probably initially not set to the default because some older devices with older radios and RILs didn't differentiate between them so the OS had no way to know.
I have seen H but not H+ yet. Someone with a galaxy S2 managed to get H+ 5.2mbps in my house. Fastest I have so far is 4.8mbps. It keeps switching between H and 3G though.

Those custom icons just seem useless to me. I have no problem getting 5 Mbit/s on normal HSPA (ie. out of a theoretical 7.2 Mbit/s) in my apartment.
The reason the icons switches from 3G to H and back is because it will go back to normal UMTS when the connection is idle. It's totally normal.

[Q] Force 3G connection

I have a AT&T Play 4G. I was wondering if it would be possible to force a 3g connection on the phone? My Play is rooted and has the bootloader unlocked. I am currently running DarkForest's 3.1 rom. I know you can force 2g. To me my phone switches 4g to 2g alot and thought maybe 3g would be a better way to go.
Thanks in advance Andy.
You force 2g by selecting ' GSM only' and 3g by selecting 'WCDMA only' afaik on a stock rom. No idea about darkforest.

I know how to force WCDMA. But it has H in the signal. I was try to get just 3g.
WCDMA refers to 3g. The H symbol stands for High-Speed Downlink Packet Access (HSDPA). Both are indicative of 3g itself.
