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 ...)

I've used those values for many months, along with

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

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!

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.

Hi all
I have an annoying problem with my sensation, well i say annoying its more frustrating.
I noticed when i look at my phone the 3G symbol is next to the upload and download arrows, when i click on a web page it pauses for about 5-10 seconds and then changes to a H symbol and away it goes.
I understand what it all means that H stands for HSDPA and its faster etc.
The problem is this, my wife had a HTC wildfire and my Mate has a HTC Desire and were all on the three network, so tonight when we were ll together mine was the only phone showing the 3G symbol both of theirs was showing the H constantly and was quicker of the mark when we compared speeds on the net.
anyone any ideas why i have the 3G symbol showing when the other 2 on the same network have the H symbol?
Thanks all

Each HTC device most likely have different radios, whereas you will get different speeds.
would you not think the sensation would have the best radio? with it being the better phone??

That's subjective. That's why there are so many various radios available here to try, depending on where you are.
I mean, at home, my Nexus One gets better reception than my Senny.
Just a quiick update, i have restarted my sensation by holding down the button etc and since then its had a constant H symbol. Can this be a fault of the phone do you think? does anyone else get the 3g symbol on there phone?

Just a quiick update, i have restarted my sensation by holding down the button etc and since then its had a constant H symbol. Can this be a fault of the phone do you think? does anyone else get the 3g symbol on there phone?
Thanks again

Right now I have the 3G symbol as we speak, as soon as i hit the submit button I will get the H icon.
Edit: and it did.
Still my Sensation might not be as fast as previous phone which was and LG G2x and it would constantly beat my Sensation when it came to speed test but what I can assure you is that I can now watch HD videos streaming off YouTube without constantly buffering like my previous.
I look for reliability and real world experience more than numbers, statistics and benchmarks.

Thanks for your reply, do you get an annoying little pause when it goes between 3G and h sometimes?
I have the same problem.
I had it also in my previous smartphone, HTC Desire.
I tried to change my SIM with another (different carrier), and the other SIM went perfectly on constant HDSPA.
If I put another SIM which has the same carrier (I have Wind) it will have the "3G-standby" problem.
I haven't tried to put my SIM on another smartphone (not HTC), so I don't know if it's an HTC-specific problem.
I've ever wanted to figure out the problem and searched everywhere for a solution, but nothing. I've tried thousands of tweaks, hacks and speed improvement guides, but none of these solved the problem.
Which carrier have you got, and where do you live in?
EDIT: Oh, and I have the same problem with every radios, so I think it doesn't matter.
This isn't a bug it's a feature... Depending on the rom, typically the phone switch from H to 3G when no data is being transferred.

I doubt it, if i put another SIM in the sensation, it will show H icon everytime.
By the way, you know how to disable this feature?
yea i doubt its a feature too as since i have restarted the phone i have nothing but H symbol.
I am on the 3 network and in the UK
Not 100% sure, but think it maybe a feature in that when signal strength is low it drops to 3g when idle to conserve power as hspda uses a lot of juice in poor signal conditions. There are lines in build prop starting ro.rill which can be changed to alter your H and 3g and g values. Did it on my X10 a year ago following a guide on here.
ro.ril.enable.3g.prefix=0
ro.ril.enable.dtm = 0
ro.ril.gprsclass = 12
ro.ril.hsdpa.category = 10
ro.ril.hsupa.category = 6
ro.ril.hsxpa = 3
ro.ril.enable.ganlite = 1
These are my values on my sensation xe, running aosp rom, and I don't see 3g very often. Take a back up and give it a try, don't forget to reboot after applying new values to see if it works. If no change or worse, then just restore your backup file.

I will try. Thanks.
What are that variables referring to? Are there a guide explaining that?
(many thanks)
I tried editing build.prop like that, but it didn't solve anything.
Maybe here I should increase or decrease some values. But I don't know which variables should edit to.
Cincinnati Bell 4G vs T-Mobile
I bought an unlocked HTC Sensation made for Cincinnati Bell about 3 weeks ago. Since day one, I could only connect to T-Mobile 3G network. Occasionally, the H symbol showed up, but it was very rare.
Called T-Mobile, they asked me to come in to one of their stores to swap a new SIM. In addition, they reset the network service on my account and confirmed that their computers showed that I'm in a very strong 4G network. Still, I could only connect at 3G.
Finally, called HTC. After asking me for the IMEI, the HTC rep. told me that the Sensation 4G's made for Cincinnati Bell have different frequencies. That's why it could not connect to T-Mobile 4G network.

So, with your Cincinnati Bell you could only connect on T-Mobile 3G network? Is that roaming?
If that, I think you're not talking of the same issue on switching between 3G-HDSPA.
Just wondering if any one else gets this, sometimes my signal just drops out and I get no service.
Then it comes back it does not happen all the time, I live in a big city Leeds infact so signal is quite strong.
Just wondering if it could be a fault with the phone?
Thanks
I've noticed it happens to me too.

It is definitely possible.
I'm on AT&T and have the correct APN settings and have called AT&T with my IMEI. I have significantly worse signal than with my HTC One X. I am not comparing bars to bars, but rather where the signal drops completely. In places where I had low signal but still connected I now have nothing.
Straight talk using at&t Sim and notice radio drops..

T-Mobile on stock ROM i had my first signal drops.
I was fine (or at least never noticed them) from the time i got my phone (day one) without any drops here in orlando.
Drove over to Tampa/Venice Beach area this past weekend and noticed some drops. Had about 6 drops according to my battery stats in 2 days. i had good to excellent coverage the entire time except when it would drop comlpetely (outline of signal bars)
would connect in a couple seconds, but i noticed over night, it would drop for a pretty large amount of time (like 10-15 minutes at a time.)
Mmm defo seems like were all having the same issues, wonder what it could be
Sent from my Nexus 5 using Tapatalk
I had this issue too, and here's how I fixed it:
By default LTE is enabled, meaning the phone will periodically scan for a LTE network. If you're in a big city, you're likely to find one. Your phone will attempt to connect. However, it fails, meaning it will have to rescan the HSPA bands to connect back. That results in a few seconds of no service. Why can't it connect to LTE? Because by default, the APN is not the LTE APN, for Rogers at least. I'd assume AT&T would be the same. You can test this by dialing *#*#4636#*#*, selecting phone info, and selecting LTE only. You'll see that there is no service. I tested this in an area I knew had great LTE coverage, and that led me to the conclusion that it's LTE causing the signal drops.
So how to fix? Simple, just change your APN to the LTE APN for your carried. To do that go to Settings -> More -> Mobile Networks -> Access Point Names. If you're experiencing this issue on Rogers, change the APN field to ltemobile.apn. If you're on another carrier, you'll have to search for their LTE APN configuration.
After doing this your phone should start connecting to LTE again, and you won't get those annoying signal drops.

So yeah the next update will probably fix the issue. It's not so bad in the meantime, Lightflow sill notify you that your nexus has lost signal, and you still get the internet and incoming calls.
We're not alone. Supposedly Google is "aware" of the issue.
i've hcanged my setting from '4g' to '3g' to see if i notice a difference (hopefully will) then when 4g is released or i get a 4g sim, can move it back up
Yes, I'm having issues too. The real problem is the fact that I have a Wilson cell booster in my home (supposed to have up to 5000 square foot range) and my n4 had full bars most everywhere inside. With my n5 It shows 1 to 2 bars if I'm lucky and quite often drops to none! The only way to get full bars Is to stand right under the indoor antenna. Not impressed, and I sure hope this is fixable!

I hate to revive a dead thread, but I was wondering if people were still having problems. Once or twice during the day that I can see I will lose signal for a few seconds only to have it reconnect. Running 4.4.2 so the latest update did nothing to help the problem as far as I can see and I have messed with my APN settings. On AT&T. The Google thread seems to have a lot of different problems on the same thread, and it is a bit unclear if people are still having this problem. This is very annoying for such an otherwise spectacular phone. Thanks and sorry again for reviving the thread... :fingers-crossed:

Actually, there have been several threads on the issues associated with this (emergency calls only, missed calls, no signal,etc.). Ongoing and unresolved for some.

Appreciate the speedy reply. Hope Google gets on this fast. I also have LTE connection issues which has plagued both this and my original device so I am pretty sure its a radio issue. The phone loves to stay on HSPA+ even when there is a decent LTE connection: it's last in the pack to connect to LTE and first to disconnect when compared to others on AT&T.

My N4 with a combo radio sticks to LTE a tad better than my N5 with stock radio. Sadly, morrislee hasn't fiddled and combo'd N5 radios, and I'm not sure they've been tested and sussed out like the N4 radios. Citing the fact some with issues have flashed all the radios so far with minimal success means we wait for Qualcomm, after Google kicks them in the you know where.

Hey everybody:
This is kind of a last gasp for me. My HTC One S suffers from the usual that you read about - "Preparing SIM" messages, constant error reports on bootup, random reboots. I honestly hate the phone.
So I installed a custom ROM. I unlocked the bootloader via HTCDEV, then I used the 12/20/13 CM11 (KitKat 4.4.2) with the 12/15 GAPPS.
The phone worked OK except now I was able to see what I've read about, and probably unknowingly experienced with the stock ROM, and that is the phone constantly flipping between Edge, 2g, HSPA, HSPA+, etc.
So, I decided to try a new radio. Did it a million times on my old G2. In order to get S-OFF to update it, I used the RLL to bring it back to stock Jelly Bean, then Moonshine to set S-OFF, SuperCID'd, and restored it with CWM. Then I installed the 1.20.x radio and at that point, all heck breaks lose with the data network connectivity and even cell signal. I might have no cell or data signal. I might have a cell signal with Edge. If I get up and move, it might go to HSPA, then I might lose everything again. This is much more pronounced than what I witnessed when I first installed the CM11 ROM.
I've tried reflashing the original 1.13 radio and it's no better. I went back to the 1.20 radio and even wiped and reflashed CM11 and GAPPS from scratch. Still very inconsistent data connectivity, so I'm not necessarily convinced it's the version of the radio because they're both pretty darned bad including the original version.
Has anybody been through this and gotten it straightened out? This is strange that even going back to the old 1.13 radio doesn't seem to help.
Thanks for any ideas...
Type: HTC One S, S4, S-OFF, SUPERCID
HBOOT: 2.15.4444 (Moonshined)
Image: CM11 (12/20/13 - 4.4.2)
Radio: 1.20.50.05.16_10.31.50.08L
Who is your carrier? If it is TMOUS you will probably need to make some adjustments to your /system/build.prop file. When I flash a new ROM I have to make the following additions/changes before my data connectivity is stable:
Code:
pm.sleep_mode=1
ro.ril.hsdpa.category = 24
ro.ril.hsupa.category = 6
ro.ril.hsxpa = 4
ro.ril.radio.svn=19
ro.ril.fast.dormancy.rule = 0
The setting "ro.ril.fast.dormancy.rule=1" probably already exists in the file, so it will either need to be edited or removed. The other settings should not exist.
The changes that actually allow the phone to maintain a data connection (as I recall) are "ro.ril.radio.svn=19" and "ro.ril.fast.dormancy.rule = 0". "pm.sleep_mode=1" allows the CPU to completely power off, and the "ro.ril.h*" settings set max speeds for different data connections. I'm going off of what I've culled from various posts and forums, so I may be off the mark on some of my descriptions.
Here's one post briefly talking about these settings:
http://forum.xda-developers.com/showthread.php?p=48276115#post48276115
You will need root access and your /system partition will need to be remounted as read-write to make the changes. Ask or search if you need help with those. Of course if you're not on TMOUS, then I have no idea...
Yes, T-Mobile US is my carrier. There's another thing I found. If it go into the phone's testing facility (*#*#4636*#*#), I notice that it's set to WCDMA preferred. If I set it to WCDMA Only and give it a few, it does go to an HSPA/HSPA+ connection. However, that setting appears to be lost between restarts.
What I don't get is that when I first flashed the CM11 ROM, I at least had the intermittent E/2g/3g/HSPA connections. How, if I go into that testing facility, it is stuck on Edge (and more consistent since my last flash). I will read the thread you provided a URL to. Thanks very much!

OK, I did these build.prop edits. Unfortunately, they've gotten me nothing. Then I went and investigated them a bit more and tried two other minor changes to build.prop (one of your parameters and added another). I'm still stuck on the Edge network. If you do a lookup, you'll see plenty of others. I think this phone is pretty much worthless - as it's been from day one. It will be my last HTC phone. By contrast, my old G1 and G2 are still working. There are tons of reports about One S phones suffering serious issues like this.
I appreciate your help and certainly, if anybody has a eureka moment, I'd love to hear about it. For the time being, I'll most likely see about getting my old G2 reactivated. Others have reported that the only way they've gotten this fixed is sending it back to HTC under warranty. Mine is out of warranty, which is the only reason I decided I'd do it. It was such a bad phone, I had nothing to lose. The next one I buy will most likely be the Moto X.
Thanks again for the help. I absolutely appreciate it.

Sorry I can't be of more help. I'm still fairly new to this phone, but I quite like it. I suppose I've been more fortunate than others in that I haven't had any real problems with it.
It's not a problem and I'm grateful for you trying. The information you provided was also interesting from a learning perspective.
I reran the RUU on it, just to see if it would make any difference. This made it so I USUALLY have 2g connectivity, but that's as far as it goes and it's not good enough. I have lost that at times, but for the main part, it's consistent with 2g.
T-Mobile is sending me a new SIM to get my old G2 reactivated. While it's only about a quarter of the One S speed, it'll suffice. Unfortunately, the SIM it had couldn't be used because too much time had elapsed since the phones last use. That should be here Monday and that particular phone was WAY more tolerant of different images and radios (knock on wood!). It's currently running a Jelly Belly image of Android 4.2.2 (if I remember), so this should be interesting.
As for my HTC One S, I'll most likely give it to my son to use for games and media. With nothing more than 2g speeds, it's worthless to me. This phone has been a complete and utter piece of garbage since the day I got it. It's funny that my excellent experience with the T-Mobile G1 and G2 by HTC was my reason for buying the One S over a Samsung model. Now that phone is the reason I won't be getting another HTC. Strange how that works.
Again, thanks VERY much for the help!

Weird, I had a desire z (same phone as g2) and it had really bad reception while holding it. Would lose all signal in the house. All my other phones used have been fine and pretty well equal - nexus one, desire hd, one s, my girlfriend's iPhone are all about the same.
This summer at a cottage my sister gs3 had no service all week, same network and the one s and iPhone
4s both could squeak some signal if you didn't touch them. A slight edge going to the iPhone most of the time I think.
Probably either a radio issue with that phone on your provider or defective hardware?
Sent from my HTC One S using xda app-developers app
It's not the provider (T-Mobile). My wife's Samsung has 4g here in the house - no issues. I took the One S out and had 2g everywhere. It's the phone.
I'm also guessing it's most likely the radio, as in a bad chip. Once you try to burn a new firmware into it, it finishes it off. Don't get me wrong, I'm certainly no engineer. It may or may not be that, or may be WAY more involved. Some people said the only way they got it fixed was by HTC replacing the main board.
The phone was a POS even before installing a custom ROM. Random reboots, constant startups with messages asking if I wanted to report the errors to HTC, random instances of NO data connectivity and then a message saying the phone is "Preparing the SIM card". I finally realize now that the occasional drops I would get while working remotely in Mexico (using a Movistar SIM) were most likely a result of this thing losing it's data connectivity while "Preparing the SIM card." The issues with this phone and the fact that it was out of warranty were the only reasons I took a chance on installing a custom ROM.
I'm sorry that I most likely sound like I'm ranting. However, I've searched all over and found SO MANY issues with this phone, that there's no way they should NOT have been recalled. Even T-Mobile told me there were many reported issues with these things. Both companies failed their customers.

Here in Canada we don't even have 2g on Telus, Bell, virgin mobile and koodo (I am on Telus), so the several phones that seem to have network problems on 2g or switching back And forth only have those issues on Rogers/fido or the small carriers like wind.
A guy I knew from highschool years ago works at fido and I remember him telling me last year this phone had some reception issues.
When telus had this phone on their website still they had pretty well all 5 star reviews. So my phone would probably be a piece of **** on a 2g/3g network too luckily they work perfectly on hspa only.

Interesting. It's nice to have the option in the case of there ONLY being Edge/2g/3g service available, but not to be stuck on it when HSPA is there.

True, at least around here though the amount of area without service for Telus/bell or Rogers seems to be pretty equal. So I'm happy not to have the issues with switching between 2g, 3g and LTE. It's hspa or hspa I guess.
