[Q] Low Signal - T-Mobile since Cyanogen10 Update - HTC Sensation

Hello all,
Have been striking out on ways to solve this. I flashed the newest CM10 about 4 days ago, and so far have been lucky to get 1 bar in outdoors areas where I usually get full bars. Indoors is essentially a no-go for signal. Wi-Fi cuts in and out.
Does anyone have any experience with this? I haven't flashed a radio since I was using HDR about a year ago, not sure if that will have an impact. Can't figure out why updating from February 10th CM10 to June 30th CM10 would cause such a reversal in quality. Using the specified firmware as per CM10 thread.
Thanks in advance

Bump for insight.

Maybe you can make a nandroid backup and try flashing albinoman's cm10.1 ROM. It seems to have a build.prop setting related to T-mobile data drop which you can probably give a try

So I flashed Albinoman's 10.1, unfortunately still getting frequent Mobile network drops on T-Mobile 0 Bars in every building since flashing, intermittent connection outside.
Edit: I was under the mistaken impression that the build.prop change was *default* in Albinoman's build. It is not, the change still has to be made in build.prop. Will report back with update.

Scratch that - No improvement making the build.prop change.

[Q] Signal/Reception on ICS (4.0.3)

So let me start off by saying I've used both stock Gingerbread, and ICS probably about equal time each so I'm used to the signal behaviours of each.
My signal was always bad where I am at University and all of my flat mates had great signal (3G, HSPDA). I took my phone in for repair and they replaced the main board, they also reinstalled Gingerbread, even though I had already S-ON'd unbranded etc etc.
My signal was great and I could use my phone properly again, internet everywhere and it was amazing.
Now I have my new SD card and I've just rerooted S-OFF'd etc and now my signal is playing up. I thought well hey if ICS is coming out soon why not just install it now anyway, because if my signal is bad on ICS i'll know it.
My question is what is your signal like since upgrading to ICS, if you have that is. I'm averaging 2/5 bars of HSPDA whereas before I was getting 2/4 HSPDA, and the overall loading is slower.
I'm running latest Insert Coin with the firmware from the user-friendly firmware thread.
Any help/tips or insight on the matter is greatly appreciated, also this is my first post so I'm sorry if I missed something.
tl;dr, since upgrading to ICS signal is crap, what's your signal like if you run ICS.
Edit 1: Done some things and found stuff out.
It seems to be for sure that ICS is to blame for this, although I'm getting weird results. I installed the ROM from MrT's (I think that was his name) and my signal did improve slightly, from 0-2 asu up to 6-8 asu, although it still fluctuates. I've tried ARHD and IC both have bad signal (definitely NOT the developers fault I was just saying).
I am gonna try the OTA next and see what the difference is. I mustn't be the only person who has much worse signal on ICS. There is zero point reverting to S-ON and going to GB, because we'll all be getting ICS this week or next anyway.
Will keep thread update in case anyone else has similar issues that they wish to fix.
Edit 2: I reverted to stock GB and then used the OTA file so now I'm at official stock ICS untouched. The signal is improved although still not as good as GB. I will wait until the release and see if I receive another update and then edit the OP again.
I also have bad reception and voice calls bad sound on ICS , I didn't use gb so I can't know the difference but on ics is crapy
Bought mine used, and the seller had just s-offed it. Ever since I've had it, all radio reception has been terrible in comparison to my N1, the worst being bluetooth, closely followed by wifi. Cell/data reception is acceptable but still not as good as the N1. I've just ordered a "new" back cover from Ebay in the hope that it's a hardware/antenna issue, I have reason to believe it might be based on the erratic nature of the bluetooth problems.
Should have mentioned first, I'm not running a 4.0 rom yet, I've been flipping between the original T-Mobile Sense g/b rom and CM7. Bluetooth's bad on both, but I've got a sneaking suspicion that wifi is better on the Sense rom, although that might be my imagination.
Thanks for your replies guys.
I will try installing the OTA file, maybe it has something different to the firmware and ROM I am using, it's worth a try anyway.
It's also worth noting that signal does go down upon picking up the phone into my hand. Right now it has 3/5 HSPDA but when I pick it up in my hand, 5 inches higher than it was, the signal drops to 1/5.
I changed firmware to 3.32 and it's little beter now. I think it's radio software problem

Yeah I'm using 3.32 but it's actually worse. I've tried a few different versions I've found around the forum and they're all the same. Signal is fine when not being used but goes down when I use it or hold it in my hand.
I hope the official OTA is not like this or I will have to send it in for repairs again or get a new phone altogether.
Mine is bad in ics too. It was ok. at gb.

Thanks for sharing, how much worse is it? For example with me I used to get about 7-10 asu in network section of settings, now its 0-2.
I guess I will try to cope until it is officially out for the Sensation in the UK and then after I can go into the shop and send it in for repair (second time).
I have the same problem before I used to get 2-3megabytes on speed test and now I'm getting half a megabyte and from the same place in my room where I used to have full 4 bars now I have 4/5 bars and I can't even buffer YouTube video

I have to say that my reception is worse on ICS. I was using gingerbread on sensation, from new, for about a month before I made any changes to my phone (root, s-off etc.) I would get a constant full 4 bar reception, it would never drop. Now on ICS, signal strength flits between 3 and 4 bars frequently, sometimes dropping to 2 or even 1 very ocassionaly. It is pretty annoying.
YES. i am experiencing the same exact problem. i have to say ics has been pretty disappointing. my signal in my room used to be 1-3 with an average of 2. Now its the same, but wit frequent drops to 0. Cmon. crappy browser, bad signal, isnt this supposed to be final version?
ok my receiption is worse at my office.. Not only worse can describe but i kinda suffer cuz of my connection. I think its related to the radio and i should try another one cuz its really annoying
im on ics, suffered the same fate, maybe this is due to DEATH GRIP?

Obviously I can't speak for everyone, but it is definitely not due to death grip with me. I can just leave the phone stationary, not even touching it and I can see the signal strength bars going up and down. I would really like to know what is causing it. I used to have perfect signal on Gingerbread.

i just wish its the ICS problem... i really love the phone, but im a little bit dissapointed as what i see on the google regarding death grip.
Same problem in my S2. I'm in a place which is like a Faradays cage, so signal fluctuates from 0 to 4. My new phone improved performance a lot because signal was fluctuating more quickly. I thought it was the hardware, I was very happy, but after updating to ICS it happened again. I think it's a kind of watchdog for signal, which is slower in ICS than GB. So should be a way to speed it. I decided to go back to GB but I can't: factory reset doesn't return phone to 2.3.5

Do all AOSP rom's have data issues?

I keep reading about data drops, 3g/4g issues on most of the Aosp roms like CM10, AOKP etc. Since we don't have the right RIL for our phones yet, is this a common problem?
You are going to continue to see data issues with jb based roms until either a) vzw releases tw jb stock rom or b) the current RIL gets improved. But yes, its an aosp jb issue.
data working fine on paranoid android build 9/6.
Try going in low coverage areas, it will drop. At work, whenever I am using an AOSP rom coverage keeps on dropping but when I am on ICS, it never drops.

I can deal with it on AOSP cause if far better then my galaxy nexus was with data drops lol

I am on liquid and I have much better reception. I work on the 18th floor and I used to drop all the time on touchwiz. Now my data is very stable. However I'm sure it varies depending on the phone. I had data issues on touchwiz, and this is noticeably better.

Supposedly there has been a fix in the last day or so. Some of the AOKP builds have them merged in from yesterday and today. I believe the CM was the ones who fixed it but not sure if they merged it in their Rom yet.

More info on this? Is it in liquid rc3?
The issue is strictly with handoffs and 3g reception, 4g should be just as strong as stock.
Also what are the chances of ever getting up to stock quality with the ril if we hypothetically never got the jb update. Just curious as to if we're going to be in this situation again next time a new version of android is released.

Liquids Rom was released before the fix. Lookhere for info and you can download the build in that thread. Other AOKP threads there are starting to add it in as well our have a flashable zip for it.

Aosp Data Problem
I have a similar problem with aosp roms.I flashed pa 2.18, and 2.17 yesterday and after initial install 4g was strong, and then i tried to switch to phablet mode and upon reboot i have no data at all. Same thing happened with aokp build 4. My imei is still there and my phone number as well, but no data what so ever. Just wondering am i doing something wrong?
I've been on CM10 Nightlies for the last month. Running CM10 M2 now.
4g reception is strong (no drops that I've noticed). In earlier Nightlies 3g used to drop every couple minutes, but with the newer ones it now stays up. However, 3g reception is still weaker than stock.
Fortunately it doesn't affect me too much. 99 percent of the time I'm in either a strong 3g or strong 4g area.

Q Radio and SMS

Currently on cyanogenmod 10 Nov 13 stable
I haven't done anything else to it. My question is that my data pretty much completely drops in malls. Which normally doesn't happen with Verizon in my areas. Is this due to the rom? If so, does changing to a jb tw rom change that? Or stock rom only.
Second if I do move to a custom jb tw rom will I be able to install the cm sms? I don't like the stock one. Ex cleanrom
Does changing the kernel on cm10 affect anything. A Grey area for me
Thank you for any input in advance.

That was/is a known issue with CM, data drops. Im not sure if its been fixed or not so not 100% sure if its still a issue. TW roms dont have that issue at so you should see better data with running those. Yes AOSP mms has been ported to work on TW, I use this one and it works flawlessly. As for the kernel you will see better performance and depending on the kernel you can underclock/overclock and undervolt. You can just make a nandroid of your current setup and flash a TW rom and try it out, if you dont like it just restore your backup.
I really doubt that it is the rom at this point in it's development. The SG3 has about the worst radio I have ever had in a phone. My SG3 can only make calls and send/receive SMS in two places in my house-- my old DX and friends and families other phones work in any room in my house including the basement. I restored back to the stock rom and took all the OTA's yesterday and my phones performance has not changed one bit. I had VZW replace the device once when about a month old due to this issue, the replacement they sent had absolutely no WiFi reception, they replaced that and a few months later that phone destroyed itself when I plugged in a OTG cable, I'm on my fourth now and the camera doesn’t focus, its got a giant black screen inkblot, and the reception issue is still the same. I am going to duke it out w/ Verizon again in a bit to try to get it replaced again. Supposedly some of these devices have working radios...
Later,

[Q] Signal Strength MD3 Updated - Possible Fix

Possible fix. jmxc23 got me thinking. Why does Moar 4 have a good signal and Moar 5 does not? So I compared the two roms, Moar 5 is MD3 and 4 is MB1. Actually all of the MD3 roms gave me a Bad Signal. I did some comparison and found the following files in the rom that were not part of MB1. I deleted them and zipped up and reinstalled and got my signal back, but only better than before. Anyone willing to give it shot to confirm or debunk. There are also two different files in Framework, but won't boot without them, so they are not included in this zip. I also deleted two lines in the build property that says required by Verizon. If they say it is required, I question it, probably a control thing. Unzip the attached and remove the files found in this zip from Moar 5, except build.prop, you can replace it with the one in the zip or edit it yourself. I now have 3-4 bars instead of 1-2. Now Moar 5 works for me.

I wish somebody could figure out what verizon changed with the md3 update that killed the signal strength for me. I have pretty much tried all the different roms that use md3 as the base, different kernels, modems and nothing seems to help. I lose approximately 10 - 15 deb on md3 meaning it goes from the high 80's sometimes higher but up to 111 or more dbm on md3. Something in the rom has got to be blocking the signal, maybe the build properties? I live in an extended network coverage area, so those of you that live in a strong signal area, may not see the difference.
On md3, lose signal, garbled voice, so it's not just the signal strength meter.
We don't know as Verizon pulled the update so that they can fix the problem.

That is why I asked the question, I knew that, but all the developers seem to want to jump to it anyway, runs fast, but signal not so good in weak signal areas.

If that was the case then why only 3-4 ROMS are based on MD3? If developers were that eager like you said then more MD3 based ROMS would released by now. It seems to me that the developers are looking for a temporary solution or waiting for Verizon to fix the problem. Also those that already have a MD3 based ROM basically using the previous modem. They might also be working on a temporary fix.
I've tried previous modems, kernels,still bad. It is almost like verizon added something in to gain more control and by doing so crippled the signal. I have noticed additional contols in the build property like wait times. The same code could be hidden elsewhere in the rom too. I don't have this problem on the ported md4 version from sprint. That rom has moved on to md3 and same signal problem. I feel that the develipers here are likely to find the problem before verizon does.

I am using MOAR ROM so I haven't gotten those problems.
I am also running moar 4.02 not version 5. Version 5, I tried and same issue. I think it is more noticed in weak signal areas only. Where I normally get 2-3 bars, I get 1 and dbm is a lot higher. I am also on a new phone.

It is always like that with weak signal areas regardless of ROM. Switching modems will either work or it won't. A network extender helps so does improving cell coverage in weak areas those are your only two options at this point.
Good hear you found a possible solution. To remind others try this only in weak signal areas.
No worries moar is going back to mb1 for better signal and thank you op for helping to make moar all it can be

[Q] Non-Open Source RIL/CSC for CM11?

MY QUESTIONS:
1) Is it possible to use the old Samsung RIL blob (not Replicant) with CM11? How would one go about doing that? The radios no longer include the RIL/CSC. Is there a version that does, that works with CM11?
2) Are there any ROM's that use the old/original RIL (not Replicant) while still keeping up with the latest Android versions ala CM? (Ie. KitKat)
Backstory:
Before I go barking up the wrong tree, hopefully someone with a little more knowledge can help me understand if what I would like is possible.
After upgrading to CM10.1, and ever since, I have had very poor reception (voice and data). Since moving to a new location, which should have had better reception, it has gotten bad enough that I started investigating things more deeply. The issue is that I will show 4 bars(-75-81db) then inevitably within a few minutes it would shoot down to -115, and then no service. Eventually it would come back. It was always really evident when trying to dial out too, either going into to no service from 4 bars while trying to dial, or within the first 30 seconds of a call.
It seems that with CM10.1 a new open source RIL was adopted (Replicant?). After hours of research, and trying new modems (UCMC1 & UXUMA7), old modems (and at one point thought I had lost my efs lol) that didn't work at all with 10.1+, I have found, as a few others have, that downgrading to CM10.0 dramatically improves reception (in service, instead of NO SERVICE) for those with marginal reception to begin with.
This is at home, usually with WiFi connected, so it is really about just having a working phone at home. I understand that it is possible that the WiFi might interfere with the cell service in some cases on this particular phone, but the dramatic difference (cell reception working vs not working) between CM10.0 and CM10.1+ with the same radio (UCMC1) for me leads me to believe that it CAN work with WiFi, at least.

honestly my first thought would be to ask about what carrier you have? does the issue happen on stock ROM? also I've never heard of a RIL helping aid with improving reception lol maybe you know something I don't.
The only time I've had your issue is when I'm in an LTE area with low LTE reception. My signal would jump from low LTE signal to 4 bars of H+ constantly trying to keep the weak LTE signal for some reason lol.

Not sure what other info you would need. Currently CM10.0 works best (not perfect but usable), so I am using that. I've tried a number of different radios(UCMC1 is currently installed, but tried many others) and settings under network preferences (currently wcdma preferred is my setting). I used twrp 2.6ish up until I tried CM11, and had to revert to CWM to get that to install properly. So the latest CWM. CM kernel obviously(?).
