I am a Hermes owner as well. On my Hermes, the icon shows '3G' most of the time until the phone needs to download. At that point, IF HSDPA is available, then the icon changes to 'H' then back to '3G' when download is complete. However, on the Kaiser, when the HSDPA switch is enabled, it never shows '3G'. Always 'H' wherever it's available, then 'E' everywhere else.
Why doesn't it scale back to 3G at all? I would rather the phone be in 3G mode than H all the time to reduce battery drain? Is this right?
You're right in that the phone should act the same way as the Hermes (H when using it, then 3G when idling). I remember vaguely some 6.1 ROMs had an issue where they displayed H all the time, whether it was using HSDPA or not.
Which ROM are you using, my friend? Might be worth looking through the thread for that ROM and seeing if it's a known issue with the ROM, and if it isn't mentioned, posting in that thread to see what other users are experiencing.
I'm sure you'll find that it's just an icon quirk rather than the phone's in the "wrong" state, so your battery life shouldn't be affected.
When I first started using my Tilt, it would switch back and forth between 3G and H icons depending on the network. For the last 4 months, it has remained on H the whole time.
I use KaiserTweak to auto disconnect HSDPA/3G after 1 minute of inactivity, so regardless of the icon being displayed, I have no adverse effects on my battery life.
In freeware PocketToolman, under OS Tweaks, there is an option that allows you to "Show EDGE network icon instead of GPRS". Untick this option to disable the "E" display.
HSUPA
I've seen in some threads that when your icon stays as an H that you are in an HSUPA enabled area. As I don't seem to live in one I couldn't tell you for sure.
When I'm in NYC, my phone is always showing "H." On my train ride between home (CT) and NYC the phone will switch between all bands depending on my location.
So, it's not just always showing "H" irrespective of the true band. And, when home it'll always show 3G until something is downloading, just like you note.
So...it has to be the band in NYC (for me) that's causing the continuous "H."
The best thing is that there is no difference in the battery drain even though the phone is constantly showing "H," and my download speeds have never been faster. I'm constantly in the 1+ mb range.

I have used Dutty's and uDK ROMS. They both act the same. I guess we really don't know EXACTLY which state the phone is on for sure. Since mine only show either 'H' or 'E'. Never ever see '3G'. On my hermes, it's mostly '3G'. I have to see if this really drains my battery quicker or not.
But all of you guys think that it's bug in the icons then?

I've never heard that. I always thought 'H' was for HSDPA. I guess they should make it distinguishable from each other like 'Ha' and 'Hu' or something.

Yes...maybe that is close. My observations:
The alpha letter(s) refers to the data connection technology. AT&T Q1-2008 network software upgrades enabled the HSUPA feature. At the same time I also noticed the constant "H". However, I caught it early and depending on where I was, I would observe "3G" (idle) - "H" (active data session) - 3G (idle)...or...constant "H". I asked some AT&T contacts and learned that they were rolling out SW upgrades across the market, over a 2-3 week timeframe.
I now get the constant "H". Same ROM through all of this.
"3G" (data) refers to older R99 technology. "H" refers to HSxPA (high speed packet access). It may be that in upgraded areas, the network now defaults to HSDPA (and eventually HSUPA) data connections if the device supports HSP...and the handset is simply reflecting this. Prior to the SW upgrades, HSP enabled devices were still getting pushed to HSP when the data session went active so there is no real difference in performance.
This "H" business has nothing to do with voice. Voice is always plain old UMTS WCDMA.
My point is that I don't think it is an issue with some ROMs. Can't really say that I have noticed any difference in battery life either.
as stated above, when I first got my phone I was getting 3g and H during download and as of late its been an H everywhere, I flashed to dutty's 6.1 rom and everything went back to 3g it dosent even give an H during download.
Might be network specific. I've tried so many roms (on TYTN II) and it has always acted that way where it shows 3g or H from time to time although sometimes it would go down to "G"
I have had the same thing on my kaiser on T-Mobile in the UK, both using the original WM6 rom and that of Dutty (6.1). But it only happens where I live! In most parts of the country, it reverts to 3G. But where I live (North London), it stays constantly on H, irrespective of the rom and the radio used. This started maybe thre months ago. Before that, it would revert to 3G. Any idea?

That only happens I think when you have HSDPA turned off. Did you check to see if it was on?
FWIW...
I just flashed to Official *TEST* ATT Build 6.1 AKU 1.0.2 Build 19209. Default icon behavior was constant "3G" after flash. I enabled HSDPA via Kaiser Tweak and icon behavior changed to constant "H". Speed tests report 875 kbps (or so) regardless of HSDPA setting via Kaiser Tweak. Toggling HSDPA on/off via Kaiser Tweak does not appear to change radio performance and speed test results. It only changes icon behavior. The radio is always operating in HSDPA mode, irrespective of icon indication.
YMMV
Im using Dutty WM 6.1. On my Tilt, H only shows up when I have an active data. It reverts back to 3g when there is no data connection or not active data

Hey Bro, I was doing the same thing with KaiserTweak; and I ran into my tilt not being able to simultaneously do data and voice when I selected anything other than: Disabled (Default)
I use Wayfinder and Google maps while driving and often talk on the phone while needing to download data such as map data.
I raised the question in another thread and a another member pointed out the bug in KaiserTweak.

I was using the same rom as you were and the NIKI radio (1.58.21.23 ). Just this morning I loaded the new Dutty rom with radio 1.58.16.27...H is shown with active data and 3g is shown with no data or not active....my location ROCKLIN CA.
Well I have just upgraded my Vodafone UK V1615 to the new official Vodafone release of Mobile 6.1, before that I had WM version 6.0.
Before the upgrade my icon like many here would stay as H in HSDPA enabled areas and then change to 3g or even G in other areas, regardless of whether I had a data connection or not. Now since the upgrade the strange thing is it varies between G and 3G but does not, ever, go to H. I am absolutely certain that I have HSDPA enabled on the phone.
The funny thing is that when I am work which is definitely an area where HSDPA is constant it still reports 3G but when I run a test it downloads at 1350kbps which is definitely HSDPA. Go figure. This rom has only been out a couple of days so it may be a bug. Be interesting to see if anyone else reports this problem, or it may be deliberate because 3g is more familiar to users here in the UK then HSDPA - maybe its to do with marketing!

So I know that ROM choice is a matter of preference...but what about Radio version?
I assume (haven't tried i yet) that the ROM is flashed separately from the radio (as it was on my 6700)?
Is there a good post somewhere regarding the pros and cons of each radio version? I could not find one...
Should I assume that the latest version is the best, and if so...what is the latest and where do I find it? (again list of all radio versions would be nice if anyone has a link to thread)?
I have a Tilt BTW with AT&T...so if there is a particular version superior for my service that info is appreciated.
Thanks again!
yeah right here http://forum.xda-developers.com/showthread.php?t=369282
Unfortunately, it isn't as simple as: The latest Radio is the best. It also isn't as simple as: A particular version works best with the Kaiser. Another factor to take into account will be your location, as the radio will determine what kind of signal you get when using your phone/GPS/GPRS/etc. Your best option is to try each of them out and see which one is best for you, i.e:
Which seems gives you the best signal?
Which seems to give you the best Battery Life?
As it seems you're new to the Kaiser, you should know that nothing is as straight forward as it seems

Is this radio capable with stock TILT? I'm currently using that at the moment while I familiarize myself with the device, and would like to recieve HSDPA and am in the philly area. I have applied the necessary kaiser tweaks, etc. but still no H on my screen and mid range 3G bars.

No. This radio requires a WM 6.1 ROM and AT&T has yet to release their official upgrade from 6.0. HTC just released their versions yesterday, so AT&T will probably have something within a week or two.

For all of you who don't have an H, only a 3G. Make sure you've enabled HSDPA. The simplest way is to install "kaisertweak." You should all be useing it anyway because it's such a great tool.

"H" means HSDPA (2nd Generation after GPRS), "3G" means UMTS, (3rd Generation), i think so...
Because ive a "H" with my non UMTS-compatible, and a "3G" with my UMTS-Compatible phones...only a idea...
I'm running Dutty's Apr29v2 with the 1.64.08.21 radio and I have 3G and H signal in Santa Ana, CA... I also tried the Niki radio, 1.58.16.27 and had great service w/ 3g & H. Battery life is a little better with the 1.64.08.21 from what I saw but gonna go back and try that radio again soon... Let you know...

and to those running Dutty's ROM- there's an option to enable HSDPA in the connections menu and/or you can use the registry hack to enable the icon.
For what it's worth, the stock tilt ROM never gave me the "H" icon- it always said 3G no matter where I was

Hi all,
First time poster, long time lurker I'd just like to say thanks to everyone in the community. You guys rock.
That said, I am having a minor issue with my G1. I have T-Mobile & my phone is SIM unlocked (I don't know if that would make a difference) and currently running JFv1.5 with the latest radio (2.22.19.26I). The problem is that when I disconnect from a wireless network, my data connection to T-Mobile doesn't pick back up. When I go into Call Settings / Network Operators I let it search for networks and sometimes my phone will have to Re-Register on T-Mobile and other times it will say that its already registered to T-Mobile but the data connection still won't work. The only thing I've found to solve that is a reboot of the phone.
This has happened a few random times when I was on RC33 and one of the Haykuro builds but it has become more frequent since I've updated to JFv1.5. Also, I dunno if it helps to mention but I went to a T-Mobile store earlier this week & swapped out the SIM card with a new one and have gotten the same results.
Is anyone else having this problem? I've searched to no avail and was curious. Thanks.
dissconnect
That's just typical crappy T Mobile service have the same prob here since I'm not close to a T Mobile tower when it loses web access it dumps the connection to reconnect
So that's it? I should chock this up to my carrier's signal being ****ty in random places? No one else has had this issue at all?

I am having this issue. Never had a problem until I updated the radio to the latest version
I have had the new radio since the JF build with cupcake. My signal was great until yesterday. It will go from the lowest to highest in the case of the bar. When I reboot my phone it takes much longer to connect to the network. BUT I think my issue is with the fact my market (Columbus, Ohio) was rumored to get 3G by this june. So I am guessing its just TMobile doing the upgrades and whatever they need to do to impliment the 3G rollout.
lately ive been having horrible service. dont know if it has to do with the new LX being released.
Hi,
I am on 5.02h and was having random disconnects on .26 radio.
I went back to .22 saffaire radio and my connection is more stable now.
I am not sure if others have experienced this as well.
I have flashed my phone yesterday with latest from Haykuro with CUPCAKE. (NO SD APPS)
Phone is running a little slower and I started having the issues with the DATA connection.
In the middle of the Web page loading, the phone looses data connection and I am only left with ability to use voice. The data connection comes back in a few minutes and same thing happens as soon as start using the data connection again.
I do not know if previously stable connection at my location all of a sudden became bad or the new build is causing this.......
just to add
Not to dissenlighten people here but t mob has crappy serivce to rural areas. I myself live in brunswick md usa. I have had. 2 bars since I first got this phone with rc30 with constant dumps to no signal all the time when it upgraded to rc33 still the same thing. Then I rooted my to jf rc33 still the same thing. After that I used jf 1.5 and it still craps out. When I go 20 mins to the north to frederick,md I get full bars and no dissconnects so if it where a radio issue there would have been some kinda difference between radio updates. I myself am a ham operator so I should know how radio signal works so when I chock it up to t mobs crappy service I do not do this lightly since the nearest tower is 20 mins either way from me. People need to stop blaming other peoples builds for this issue since the radio update is from google. If I pop a att sim I get full bar and no dissconnects cause the tower they use is closer that's how I know it's a t mob problem not an issue with the radio. Remember troubleshooting is the best way to see where the problem is. Till t mob puts up more towers and fixxes the packet loss to the phone to remedey this then we will all have crappy service which does not seem to be in the near future for anyone.
I had a similar problem when I was on stock RC30. I called in to tech support and they set up a new APN on the phone so it would switch back to EDGE faster if I lose the wifi connection. I would suggest if you're not around stable wifi, just turn it off.
Anyone having issues with network auto roaming switching on WM 6.5. I have recently installed one of the Kaiser Roms v21232.5.0.1 by "Chinhe"; Everything works great except the auto roaming feature. By that I mean that usually in areas where T-mobile (USA) don't have coverage my phone used to switch to ATT, but not any more. I have all the network settings to Automatic. Personally in my case I have to manually go to phone settings and switch to ATT as a roaming provider. Is there something you guys can suggest I should do.
Anyone else having same problems?
Appreciate your time. Thank you
Try another radio. Maybe that helps. Please check the ultimate radio thread for more info.
Cheers
Hmmm did your network change anything? I know I had chinhe before, and the place where i work there is not signals in buildings, and it was roaming! But i downloaded data and stuff even with that ROM!
My Radio Rom was at 1.71 by Emo and may be that was causing the problem. Chinhe recommends version 1.70.19.09. I have recently updated my phone but I have not got a chance to fully test it.
I will post some additional comments later on. Thanks for your prompt replies.
Radio
I had almost the reverse issue on a WM6.5 ROM. My provider is T-mobile USA and it would rollover to AT&T too often. Then would have trouble "rolling" back to the T-mobile network. (leaving me unable to make or take calls for 5 minutes or so as it connected and disconnected) It was so bothersome that I switched it to manual network connectivity. While the problem was limited to when coverage was weak(one or two bars) it had never happened on previous ROMs. I've been using the EmO 1.71.09.01 for probably a year now on various ROMs and this was the first time I had experience Radio issues. Long story short, I switched to another WM6.5 cooked ROM and the problem was resolved.
Hi there,
I'm using Revolution HD 3.6.1 with its radio and relative RIL (which becomes with the rom by default). Obviously I have S-OFFed and rooted.
I'm experiencing some hiccups in 3G data connections. I don't know if it's due to the carrier (Wind Italia) or something in the phone (maybe the radio doesn't support it at all?). I'm in Europe, precisely in Italy.
Maybe should use an european version of radio? Or what?
In detail:
I activate data connection. The phone shows 3G before, and quickly goes in H (HDSPA). Then I use many apps that needs internet connection. Within a short time it goes again in 3G and i have absolutely NO data connections. After a delay of 5-10 sec it goes again in HDSPA and everything works. When it goes again in 3G i have no data, then again H and data working.
What's the problem?
EDIT: Problem solved! See in this post.
P.s.: Sorry for my bad english
I was going to ask about something similar to this, so rather than start a thread I will post it here. I too am running the 3.6.1 with its radio, S-OFF, & rooted.
What I am seeing on boot up is the standard progressive upgrades of data networks (just bars, then 2G, then 3G, finally H). The H only stays for a few seconds then drops to 3G and basically stays like that. However, as soon as I open an internet requiring application, it jumps to show H and typically stays that way as long as a data connection is active. My Speed Test results show its 4G speeds (same as stock ROM and radio) when its showing the H, so obviously its working, I'm just wondering if its intentional that the display only shows 3G? Or maybe its set so the ROM "relaxes" on 3G, but switches to 4G when data is actually being sent/received?
~T.J.
Maybe you used to have a 'background' app updating constantly.
The G, 3G and H usually depends on the signal in your area, the H is usually for high data transfer. If you're not using the internet,downloading anything or updating anything on your phone, then why would you need it on all the time?
3g is usually the norm, so I wouldn't worry!
For my issue, my stock ROM showed me what was available in the areas as I moved around, including showing 4G all the time if I was in a coverage area (which pretty much everywhere around me is). If I moved out of the 4G area for instance, it would drop to show me 3G.
This one just shows 3G all the time, even when I'm in areas I KNOW are 4G; UNTIL I use the data connection, then it switches and shows the H. I know its silly, but I liked actually gauging my providers service by being able to see what kinds of connections were available in various areas.
The fact I have to actually open the browser or run a speed test to see if 4G (H in this case) is available in that area is a little odd to me, why doesn't it just show the connection that's available?
~T.J.
Guys, I found a solution to my problem, googling around. That's awesome.
FYI I'll post here:
1. dial *#*#4636#*#*
2. Go to phone information
3. Toggle ciphering so it's off
4. Turn off radio
5. Turn on radio
6. Toggle ciphering back on
It seems to be working to me. An half hour without hiccups till now.
I have had this problem ever since my hd2 two years ago. I thought it was normal. I'm about to try the fix. If it fixes it you are a life saver.

Aww man same thing. Maybe its supposed to be like this.
Basically for me its for example on the xda app when ill refresh something it will always say processing as soon as the 3g symbol turns to h with both arrows on simutaneously.
Maybe that's how its supposed to be idk.

Only a brief temp fix? Are you sure?
I'm not having the same problem as before, now. I hope it remains still as it is.
Everything started when I've made some tests and I've noticed some strange things:
- on every KK ROM I've tested, mobile data drops completely after some talk time. It is happening only during calls (long calls usually). It is regardless of the radio used, I have tested it with 1.13, 1.15 and 1.20...the same with all. It is also happening regardless of the call type: on BT (car-kit or headset), speaker, headset, handset. EDIT: Now I made some tests and seems like I don't have this issue anymore but instead I have the issue below. I don't know why and when this started to happen
- as soon as I make a call, the mobile data icon switches from H/H+ to 3G. As soon as the call ends, it switches back to H/H+. I've run some speed tests and it's not only the icon, it's the speed too. I get about 0.09 Mbps during a call with the 3G icon and up to 8 Mbps when not in a call with the H/H+ icon.
Now there are some build.prop entries I don't understand and I couldn't find any explanation on them. There are many threads in which some of them are recommended, some say they work, some say they don't, I am really puzzled. Below there are a few about I couldn't find any details:
- ro.ril.radio.svn = usually value here is 19 but I heard about 01, 02, 03 or 04 as well. Nobody seem to know why it's one or another and more important what does this does.
- ro.ril.hsxpa = usualy 2 but I saw many people recommending 3 or 4 without any arguments on that. What does 3 or 4 do here? Don't say it's enabling HSDPA or HSUPA because the lower values already do that: 0 = UMTS, 1 = HSDPA, 2= HSDPA/HSUPA. So why 3 or 4?
- ro.telephony.ril.v3 = now this is a nice one. Mostly I've seen this set as skipradiooff but I found more: icccardstatus, skipbrokendataca ll ,datacall, signalstrength, facilitylock. What's this all about? What any of these options do?
Now why I ask such stupid questions you'll say. If they work who cares...ok, but DO they work? Has anyone tested if they change something? If yes maybe those persons could bring some light here because nobody seems to know. And I mean if one of the above do change something, the ones that tested and recommend these settings should at least tell us what happens if one or another option is included.
Has anyone commented out for example the ro.ril.radio.svn and see what's happening? Or put 01 or 04 instead of 19 and see if any change? Cause I couldn't find any difference with this option set or not. Why is then recommended? Maybe it's particular to some carriers (I saw alot of settings related to US T-Mobile). If it's true, maybe it's good to know that only for that carrier it does something and on any European carrier it has no effect (or it has, I don't know)
Please anyone who knows some info or made some tests post here. Maybe we could shred some light into this cause after searching and searching I couldn't find anything clear. Everybody is mentioning those with one or another setting but nobody explain.
EDIT: I've start testing
ro.telephony.ril.v3 =icccardstatus - this seem to show a "no SIM" or "insert SIM" icon instead of the cell signal icon. Even so, calls CAN be made, I've tested a few. Probably this disables the ability to read SIM card status so that's why it shows that no SIM is present
ro.telephony.ril.v3 =datacall - this disables completely the mobile data. Icon for mobile data is gone and there's no mobile data access. Browser and any apps are reporting "no connection"
ro.ril.hsxpa = I hope it is not my imagination, maybe others can test as well but here's what I found. If 4 is there, most of the times I get H indicator and speed. If 2 is there, I mostly get H+ indicator and speed. So strange but at least in my case 2 seems to be better than 4 (which anyway I don't know what means). EDIT: Ok, after further testing and searching it seems that value of 3 means HSDPA "uncapped" and 4 means HSUPA "uncapped". So it could be that 4 is better than 2 or 3 but this has to be tested for each particular carrier to see if it's really improving something or not
ro.telephony.ril.v3 =skypbrokendataca ll was the fix (100% of the time) for a data acquisition issue on the HTC Sensation for TMOUS customers. Ironically, it causes a lot of 3g connection problems for non-TMOUS customers though. The problem it fixed was a blinking H or E with corresponding lack of data. Many times, sending a MMS would fix the issue as well, but not always. (thank you @nicknc for clarifications)

Thank you, I'll add this info in OP. Also that should have no impact on Ville in this case
I've also read alot about that H/H+ switch to 3G during calls. Unfortunately I cannot test myself because I don't have 2 phones but I'll keep searching. As I read, it seems there's a similar issue with those having LTE networks (or 4G how it's called). It is known that the LTE network is not capable of having voice but only data. The only way of having voice in a LTE network is via voice-over-IP that is not implemented. That it is called VoLTE (Voice Over IP over LTE) and the project for introducing it has already started but it'll take some time till it'll be finalized. Therefore, if someone is on LTE network will notice that during voice calls the mobile data switches/drops to 3G and resumes on LTE as soon as the call ends (or not...for some carriers it has to be manually switched back). This is implemented by the carrier and it's called CSFB (Circuit Switched Fall Back). The internet is full with complaints and questions related to this data drop, especially in US but it is also in Europe or other zones in which LTE was implemented. Lot of people asks how can they prevent this to happen...short answer is they can't, only way is to change the data plan back to 3G from LTE. More details can be found by searching on Google and also I found this technical article HERE (for those interested in such details)
Now what I believe (but I can't prove or test), is that for the same reason I have that switch from H/H+ to 3G. Vodafone RO has LTE implemented and it could be that when someone makes a voice call, mobile data is automatically dropped to 3G even if it is not on an LTE data plan. When I tested with someone else on the same carrier, he didn't have that dropped data but also he was not living in an area with LTE coverage so it could be that this is happening only where LTE is implemented (that's why I need more time to test and find persons who can help me).
Okay-- a few updates for TMOUS
I tried ro.ril.hsxpa set to 2 for a few days. No appreciable difference, other than an appearance of a tendency to hold onto 2G longer than the phone should in a high-coverage 4G environment.
I also tried hsdpa set to 24 and hsupa set to 6, as everyone likes to whine about how our phone doesn't support values of "28" and "7".
This is where it gets interesting. Regardless of the setting of ro.ril.hsxpa to "2" or "4", I do not get H+ indicator with hsdpa set to 24 and hsupa set to 6. When I flip it back to 28 and 7, I get the H+ indication. There is no appreciable difference in speed, but then again, I am currently getting a speed lower than what I get when at home (10 mbps vs. 14 mbps). So, it could be 10 mbps is the max available on the tower to which I am currently connected.
The upload seems to be lower than normal (2mbps), so it is likely that conditions are not ideal.
When I return home in a few days, it will be interesting to see if there is a difference there between 28 and 24.
It does appear some of these settings might have infiltrated from other HSDPA+42 or even LTE phones, and wouldn't necessarily apply to ours.
The 24 for hsdpa and 6 for hsupa is from the table I found and tells the maximum speed at which device can download or upload. It is useless theoretically to set higher values since the device is not hardware capable of achieving them

Yeah, I understand that, but the strange thing is the lack of H+ indication for me on 24/6.

Should be another reason...I have H+ and I have the same 24 an 6 values. I am currently using the following
ro.ril.hsdpa.category=24
ro.ril.hsupa.category=6
ro.ril.hsxpa=4
ro.ril.radio.svn=19 (still don't know what it does but ...)
ro.ril.fast.dormancy.rule=0 (my network doesn't support fast dormancy)

I've used those values for many months, along with
ro.ril.disable.power.collapse=0
ro.telephony.ril.v3=skipradiooff
and I always get the H+, though my data rates have really gone to hell in the last few months...5Mb is good for me these days.
Ok, and what does that "skipradiooff" do? Because nobody seems to know. All are putting that setting in build.prop or recommend it but nobody could tell why. To be honest I didn't notice any difference with or without it
Could be something specific to T-Mobile and in this case that's why I don't see a difference

Very likely does nothing. According to this commit, the hooks were removed in CM10.2 anyways

Well, I have these as default in cm on my mako. Interested to see if that HW_powersavings or the quick power on would be useful in getting fast dormancy to function without the data drops
proximity_incall=enable
power_supply.wakeup=enable
ro.config.hw_power_saving=1
ro.config.hw_fast_dormancy=1
ro.config.hw_quickpoweron=true
persist.sys.use_dithering=0
