Hi I wanted to try Cm10 and data kept blinking a on and off. I tried get ril to see if it would help the situation. No joy. I am running 3.33 firmweare and I am s off. I ended up matching the radio with different ril from xda. Result was no data at all. I restored a backup and used get ril to match my current radio and I have signal again. However I would really like to run Cm10. Is there any suggestions to help with this problem. I've never had any data problems before? Can someone suggest a possible fix for this issue? I appreciate your input.
try flashing it again, this happened to me about a week or two ago and appears to be common with AOSP (the reason for this, I have no idea) but yeah if you absolutely need data, just restore a backup for about an hour or two
Here is everything there is to know about this problem.
http://forum.xda-developers.com/showthread.php?t=1873374
The short version is...there's no permanent fix yet. It will fix itself in a few hours. But it might come back.
This problem is getting much less common on CM10 over the last 6 weeks or so. Prior to that it was a VERY common issue. It could be a combination of other problems in the AOSP framework that cause instability and T Mobile refarming their network nationwide.
Thank you for the answers ! That's good to know! I am Tmobile so yes the incompatibility makes since. I will give it another try and see how it fares. If I still get the issue, I'll just restore my nandroid. Again thank you.

Restoring your nandroid won't fix it. The problem has something to do with how the data network authenticates your device and how that authentication is done with the CM Framework.
The variable (whatever is changing so that this is not occuring 100% of the time for 100% of t mobile users) is on the T Mobile network side. So simply switching back to your nandroid backup won't fix it even though everything was working fine with that backup. Both your nandroid and the updated version of the ROM have the same flaw that can provide that unstable data connection. And whatever T Mobile is doing that is causing that flaw to show will occur on every AOSP rom with an ICS or JB base.
Switching to your nandriod, switching to CM9, AOKP, Opensensation 1 or 2, etc etc etc...none of it will make the problem go away. Your best bet is to turn data off for a few hours and try later. Just ride it out until the network is no longer creating that data instability.
Just for information purposes the developer of the basic CM10 and OpenSensation 2, Bruce, thinks that the problem has something to do with the T Mobile network not being able to differentiate between it's MMS network and it's Data network. Those two operate on the same bands and are very similar, but there's some subtle difference in them so the phone knows the difference between and incoming MMS and an incoming data transmission. Bruce has done some work to try and help that. Some people saw the problem stop cold and other people have seen it greatly reduced. That's not confirmed that that's the issue and the improvement may be coincidental. With T Mobile refarming it's network city by city they may be gradually changing changing the way that's done and inadvertently fixing the problem.
How bout a Sense ROM? I flashed ARHD when I had this problem and had instant data
Sent from my HTC Sensation
Thank you both. And thanks for the explanation. I suppose I got lucky that my backup did restore my data after using get ril again it was stronger. I did also hear T-Mobile is having tower problems or something like that. I'm wondering if that had something to do with it also. Maybe I'll give sense a try again. Too bad I was really hoping to give Cm10 a go. But I do need data. Again, thank you for your help!

We cant blame T-Mobile for this issue when we can clearly see it occurring ONLY on a specific handful of Sensation ROMs.
I've gone from a solid data connection on the stock Sense directly to a very unstable blinking data on bruce's CM10/Kang and OpenSensation 2 within minutes. Not a coincidence. All the while, my T-Mobile CM10 Nexus One sat next to me without an issue. Over the next day my gf complained about her Sensation's lack of data and still my Nexus One is fine.
Is being S-ON to blame?
idk, I guess I'll try the Android Revolution HD ROM next.

What build date of Bruce's ROM did you use? This was fixed about 2 months ago for most people.
When you downloaded the ROM, did you get the first one on the list?

I just flashed last weekend. I used the latest builds from http://goo.im/devs/bruce2728
This one: cm-10-20130109-bruce2728-pyramid.zip (data blinking on boot)
Then this one: OpenSensation2-20121123-pyramid.zip (did not fix) (so I followed it with OTA Dec 3 - did not fix)
My Method (coming from Official ICS Sense w/ hboot 1.27 on T-Mobile Sensation 4G):
HTCDev unlocked
left S-ON
flashed latest CWM then did a "wipe data/factory reset"
extracted boot.img from cm-10-20130109-bruce2728-pyramid.zip and flashed it via fastboot (necessary for S-ON)
flashed cm-10-20130109-bruce2728-pyramid.zip via CWM
switched recovery to latest 4EXT with SmartFlash enabled
flashed OpenSensation2-20121123-pyramid.zip over CM10 (no wipe)

Hi. I was using my Sensation last night, went to bed and woke up the next day only to find that my 4G connection wasn't working! The signal bars were white and the icon (currently an H) is flashing. What does this mean? How can I fix it? I can only use Wifi at the moment, and I DO NOT pay an extra $10/mo to deal with this! How can I fix this? I've checked my data settings, rebooted my phone, scanned fir viruses, but can't figure it out!

this happened to me the other day, even in 3G/4G mode my data would never connect and E would just keep flashing over and over again (in like 10 sec. intervals) thought it was a ROM problem so I restored a backup and sure enough, the problem was still happening. I could still make calls and send texts fine tho. its not happening to me anymore, but I found it weird. could it possibly be T-Mobile messing with their towers or something in preparation for LTE?
Well, I'm not sure what caused this very same issue for me a couple days ago. I can say that it ONLY effected my AOSP (CM9) rom, but my Sense rom was unphased. It seems to be a common recent complaint in the OpenSensation thread...
I've since then done a fresh install of CM9 RC1 with the addition of Tamcore's kernel. Although I'm not experiencing the described symptom any longer, I can say that my data speeds are far from exceptional. I'm not sure what is going on, but it does seem to be carrier related.
I experienced the same 1 day after flashing CM9 RC1. I re-flashed the Virtuous Inq. ROM I was using previously and the problem went away
My phone went back to normal later on. I think you were right mulletcutter, they might have been servicing it.

Same data connectivity issue
I have two sensations, both shows similar data connectivity issue on TMobile. Data signal jump to connected and not connected for couple hours, and eventually problem will go away. I have both phones rooted running either CM9 or Kang. So far I have tried couple following things but no solutions. I believe its HTC Sensation hardware issue:
1. Flickering so far seen usually after night long charge in the morning. It will last couple hours, some time days.
2. Changing/reflashing ROMs did not help at all and saw same issue continued.
3. One of my friend has Sensation and he also has seen same issue.
4. Some time going into Phone application(Dialer) and then Settings/Advance settings and come back without doing anything helps but not always.
Please post here is you have temporary/permanent solution or even know the root cause of this data connectivity issue.
Also thinking to call Tmobile to get some kind of help but not expecting much as I bought phones more than year ago but less than 2 years. I don't want to give any more commitment/agreement with Tmobile as planning to move to value plans to save some money. If Tmobile does not help, thinking to try American Express to conver it under extentended warranty as I paid by AMEX credit card.
Thanks
Have you tried the application get ril? I was having some issues myself, I'm also T-Mobile. I tried get ril and found out my radio and ril we're not matching. The application suggested a ril for download and once I did that I went from one bar of connection to five bars of connection on H. It made a big difference for me. Perhaps it could also help you? You can download get ril from the market. It sure won't hurt to try. Best of luck.

Its a defect in the basic aosp framework. There is nothing you can do to fix it. There is also nothing your usage did to start it.
The good news is that it should disappear on its on after a few hours.
Check my threads started history. You will find a thread near the top of that list showing almost all there is to know about this issue. I think my thread might be linked in the first 2 posts of the cm10 faq thread too.

Hi, i hope someone can help me but im running a Mytouch 4G slide with Cyanogen Alpha 5 with s-on and everything works great and has been for the past 2 days since purchased and rooted it, Today however i have been having constant data loss. What happens is on my signal bar i can see the H come and go come and go come and go for about 5-10 seconds intervals, when it comes, it immediately goes away and then comes back after about 5-10 seconds. I tried to do a factory reset and after losing everything i hoped it would fix it but it only fixed it for about 5 minutes then it continued doing the same exact thing as before but i have great signal reception. If anyone has any clue on how to fix this or maybe get a new Radio that fixes it, i would be more than glad to turn S-OFF as it is currently S-on. Thank you and i really appreciate all the hard work and help!

I'm having the exact same problem and have been running CM9, Alpha 5, S-ON since a few days after it was released with no problems at all. I didn't notice it until I got to work since I have wireless at home but have not had data all day. I called T-Mobile and they're not experiencing any outages in my area (Philadelphia) so that's out of the question. The only changes that have been made to this phone have been making sure to keep my apps updated.
I know this isn't an answer to your problem but you're not the only one having it. Hopefully, someone can provide some insight.

Note that I've had the same data issues on CM9 Alpha5 with two different devices. I was able to replicate the intermittent data issue on my sister's mt4gs. Her's was s-on. Then I s-off'd her phone using revolutionary and still had the data issues.
I reflashed back to stock 1.63 and data worked fine. Then I used JuopunutBear to s-off and flashed CM9 Alpha5. Data has been consistent and flawless on both devices ever since.

Changing the APN setting to internet2.voicestream.com worked for me but I'm still curious as to why after a month of running CM9 A5 with no problems, the data just dropped on me today.
I think this is nation wide and not just a rom problem a couple people I've talked to have been having data/signal problems all different phones.

Not necessarily, i think its just the Mytouch 4G slide running the cyanogen.. Im running an HTC Amaze with revolution ICS 3.6 sense s-on for over a month now and it has worked great no problems whatsoever... as for this Mytouch 4G slide, i still cannot get this problem fixed, they phone gets data back at times and then the problem hits it back just a couple hours later and it is very frustrating. I have also tried to fix it by doing the whole root process again and that only fixed it for 24 hours till the next day so thats out of the question as to answer post #2. I guess i will just have to wait and see for a new cyanogen update to come out for the Mytouch 4G slide.
Ive been having problems with my data for a while. My conclusion is its not any roms or radios ive used, its the phone. T-mobile thinks the same thing. After seeing bruce's CM10 thread clogged up with posts about it i figured we could discuss it here.
A little more explanation would help. Problems with data is vague. Specifically, what about your data connection is considered a problem ie is it not connecting? Is it disconnecting? Do you only get 3G or 4G

I used to have data issues all the time with CM9 & CM10. Sometimes reflashing the ROM would help, but it got to the point where I had to flash a Sense ROM to get my data working and then flash CM again. That would work for a few days, but then my data would start cutting in and out again, usually after turning off WiFi. I finally formatted my SD card and have been free of data issues for over a week now.
It seems that perhaps some file or other from Sense ROMs that is left on the SD card is causing a conflict with AOSP and/or T-Mobile's APNs.

the service is shown with signal flashing h then it will go off and drop its connection why =[!!!
it works when i flash a sense rom but not bruce's rom!
I just did a quick format. I forget to mention it in my previous post, but I also changed my radio and ril from the latest ones to the official T-Mobile ones - 11.69A.3504.00U_11.23.3504.07_M2 and 4.0.0024HMQ.

what was your problem with your service?
and could you provide those links please?
threw the OP up this morning before an interview just to get people to shut up in bruce's thread about it. most people with issues that sound similar to mine dont seem as bad. basically, i just have terrible service. even in places where i shouldnt. my network when i get to either 3g or H just bounces between the two. even the one time i actually got full bars of 3g it just kept bouncing to H and then bouncing back. if i have two bars of edge in my livingroom and try to send a text, itll just drop the service completely. if someone makes a call to me and im on 2 bars or less of any network it will just drop the network completely. happened once i moved from vegas to phoenix, flashed every ril/radio combination i could find. every one is the same. talked to other users in close proximity to me with a sensation and they said they get great service everywhere. happens on every rom as well. messed with APN settings, went to the store and got a new sim card. everything. Like i said, im certain my issues are worse than everyone elses but itd be interesting to see what different groups of people are experiencing with data issues to see if its something with our phones.
BTW - tmo at the store said "buy a new phone" AWESOME customer service i must say.

I had this exact same problem on cm9. I've had to take refuge in viper's sense 4 rom until I could figure out what caused it. I was able to fix it once before by flashing a combo of roms and radios. Then it happened again and just stayed on viper as it doesn't reoccur on a sense rom.
Note: This happened to me before cm10 was even developed. I was running AOKP at the time. It also happened on a backup that was 2 weeks old before the problem first happened so its not entirely rom related.

So this sounds just like my issue. I've been running on BADOSP's ROM which is based on AOKP M6 for the past week or more with zero issues with data connectivity. Never a problem getting 3G/H where I was supposed to. I flashed CM9 last night to check it out and decided against it and reverted to my backup. I was running fine through the night on my backup but then set it in airport mode last night, came out of it and flashed a basic AOKP install for fun this morning. After that I can't get a data connection to stick on any AOSP type ROM. Not in CM9, not in AOKP, I've cleared/formated EVERYTHING went to backups of systems that used to work and now don't, nothing. Finally, I had a nandroid from Vipers Sense4 rom as well and it was basically exactly the same - seeking refuge for a working system in the mean time.
Seems no matter what now I cannot make an AOSP ROM work but I'm at least functional in a Sense 4 ROM. I would love to know what happened if anybody figures it out.

So in case anybody else finds this. I was having no problems in sense based roms it seems and only AOSP roms fail to establish a data connection. I had read a few posts in different places about wiping the SD Card but I didn't want to do that for nothing. So I restored a nandroid of an AOKP ROM and then selected to power off from EXT4 instead of rebooting. I then popped out my SD Card and powered on. It took a minute for the data to establish but it worked. I put the SD Card back in and it kept working. I have rebooted since then and it STILL works. I'm not sure what prompts the problem but ultimately this solved it for me. Been running 24 hours now with no issues. Hope this helps somebody else.

Unfortunately, this worked for a day and a half. This morning it suddenly started doing what it was doing again. Haven't had any time to troubleshoot or try anything as I'm about to be traveling so I had to revert to Viper's Sense ROM again.
I'm also having the same problem. It just started a couple of days ago when I was running CM9. I figured a wipe and flash would fix it. I am now on CM10 and still having the same problem. Anyone have a solution?
5/19/2013 Update: The bug might be dead! Like for real this time. See this post, post number 14 in this thread with an explanation of what to do.
10/25/2012 Update: TRY THE LATEST BUILDS OF BRUCE'S CM10 STARTING WITH THE 10/25 VERSION!
Bruce has made a change that helps differentiate between the regular data stream and the MMS data stream in an attempt to see if that was what was causing the instability issue. This is only on Bruce's CM10 Kang as of 10/25. If you are only another CM ROM, flash Bruce's (even if just for a minute or two) and see if the data bug goes away. Please report back if it did!
If this does cure it, I'm sure Bruce will share the sollution to all other devs and your favorite other AOSP ROm will have the cure shortly.
Updated 10/24/2012
This is a detailed description of the 6 million or so things that various people have attempted to do in order to rectify the blinking data connection problem plaguing T Mobile USA users on AOSP ROMs for the Sensation. This issue is non existant in Sense based ROMs.
The problem has something to do with how the Sensation authenticates itself with the T Mobile Data Network. It's not based on the cell towers as voice calling is unaffected. The theory is that the AOSP framework lacks the proper authentication certificates for part of the data network and when the phone is routed to that part of the network, it gets kicked off teh network, then continually retries to connect.
This was and issue on the Sense Gingerbread Stock ROM in 2011 but T Mobile and HTC patched it. All Sense ROMs are free from this bug. But no one knows what exactly the patch was so AOSP ROM's have not been able to be cured yet.
Short version....
Problem started for me on Bruce's CM10 rom. But it's reported on all CM10 variants and most CM9 ROM's as well.
One day I noticed that data wasn't connecting well. It would blink on and off. Sometimes it would stay on, but if I turn it off then right back on, it might go back to blinking.
The problem exists on all AOSP roms (AOKP, CM9, all versions of CM10) even after full wipes and restores of known working nandroids.
Cell signal for voice calls works perfectly. No problems whatsoever. So the phone is connecting to T Mobile. It just won't get data.
Long version....
To fix this I've tried the following...and how each does or doesn't work.
Switch to 2G networks only and switch back. Problem remains, and still blinks E on the EDGE networks rather than being solid on them.
Updated the radio. Problem remains.
Updated the entire firmware package. Problem remains.
Superwipe and flashed Sense, verify data works well. Then regular wipe and flash a fresh install of CM10. Problem remains.
Flashed clean version of CM10 and fixed permissions. Problem remains.
Made calls from the phone. Some people have reported that this helps temporarily.
Sent myself a text message. Some people have reported that this helps temporaliy.
Turn on airplane mode for a minute then go back to normal. Some people have reported that this helps temporarily.
It's not related to Wifi at all because I've created the error on fresh installs of CM10 before ever turning Wifi on.
Formatted SD card. Problem remains (and just to be sure I got the error while the blank formatted SD was removed from the device)
Checked the APN's 100 times. They are correct.
Spent an hour on the phone with T Mobile. Their tech said everything looked good on their end. He cleared the SIM and reactivated it. Problem remained.
Other people have gotten new SIM cards and found that while they helped right away, the problem eventually came back.
The only things that have shown any help to multiple users are in bold above. There are various reports of 100 other 'fixes' that people swear fixed the problem for them. But all of them involved the phone disconnecting from the network and reconnecting. That appears to be the key to get data working again temporarily. Making calls and sending yourself text messages also forces authentication on the T Mobile network without breaking the original connection.
If you want more details or want to review the logs to see if you can figure it out, logcats of the problem are located in this post! Click here for logcatty goodness!
Here is the real kicker....
Everyone once in a while...it connects. And once it's connected it'll stay connected until I turn the connection off or reboot the phone. Then it'll go back to blinking in and out when I try to turn it back on.
Just another note, the data is finicky on my old LG G2x also on TMobile with AOSP based ROMs, talk works, but cell data won't come back after going into airplane mode and out, until a reboot. It works fine on official TMobile ROMs. I suspect there may be some proprietary cell data negotiation between handset and Tmobile towers that AOSP code doesn't have.

Okay here's an update on this for anyone who finds this thread through a search or Google or something....I'll try to describe this using the simplest terms possible so those of us who aren't cell tower engineers can understand it. (And I assume that's most of us, including me!)
The latest running theory is that the issue occurs due to the way the phone is handed off from 1 tower to another.
As you move your phone is handed off from one tower to the next. You get unregistered with tower 1 and reregistered with tower 2. That's normal.
However if you are within range of 2 towers you can't be on both. You have to be registered with 1, and that's supposed to be the stronger one. But AOSP ROMs lack a T Mobile certificate that authenticates which tower is supposed to have priority. So when the data is blinking you are getting bounced between 2 towers because the phone is trying to register with both.
The latest version of Bruce's CM10 ROM (Dated 10/10/12 and with TMOUS DATA in the rom name on the download page) supposedly includes patches that fix how this authentication works. And I only say 'supposedly' because the patches have only been up for about 12 hours so the jury is still out on how well it works. Personally I've been on it all day today and haven't had the data issue yet. But it can be days in between seeing it. So it'll take a while to know for sure that it's fixed.
If this turns out not to be the exact cause of the problem, it's something similar and a final sollution should be found soon.
Update: This have never been substantiated, and several users with the bug have reported knowing for a fact that they experience the problem when in range of only 1 tower.
Hi,
I have noticed with JB ROMS that you get 7 or 8 APN's,most of which do not apply to me.
Have you tried (making a note of your one first) and deleting all the APN's
Reboot,and just install yours.

That's one of the 1000 things that's been tried, to no effect. If he APN is set to the correct one the extra APN's are ignored.
Nothing that you do within the phone can cure the problem. At most, forcing the phone to re-register with the tower is the only thing that can help, and that will be temporary if it works at all.
The best bet now is to hope that Bruce fixed it with his latest additions to CM10 now that we understand what the actual problem is (or at least that we think we do)
Update....
T Mobile data is still broken. It has not been fixed yet. The latest theory may just be one more in a long line of theories that turned out to be wrong.
There are days when I really hate this phone.
Thanks for the update. I've been monitoring that thread occasionally, but it has way too much traffic for me to keep up. I was close to switching to it, but I need good battery life and reliable cell service over any smoothness benefits of JB, which is why I'm sticking with HyperNonSense ICS for now.
been experiencing this issue for a couple months myself. currently stuck in a no data bout as we speak. i'm wondering if it has anything to do with the amount of data we've used. i noticed this last bout started right around the time i passed 5gb. should also be noted i'm on the unlimited 4g plan and tether like crazy. i guess i'll know if the problem persists until my next billing cycle. for now i'm stuck with a sense nandroid and crack flashing aosp daily to see if it's fixed.

I have tried the SIM swap fix. And that has apparently worked. I've been using in good for about the last 6ish hours without any problems. :good:
So i'd give that a shot if your willing.
I've been using CM10 KANG since it was available for HTC sensation. Never had the data blink issue. Recently, my phone started to have this issue. Data would simply not connect with CM10 or CM10.1 with any radio/firmware combination. I also noticed that when I travel to work, i get data say after 10 miles away from my home and it continues to work after coming back home. However, after restarting the phone, i hit the blink problem again. Wondering if its because of some cell tower maintenance/upgrade near my area.
So I was on bruce's ROM until a week ago and this never happened while on his ROM. Just upgraded to albinoman's ROM and this started happening. I have to send myself a MMS picture to get it back again. Hope this helps
Fix
Ive had this problem on and the only thing that seems to help is flashing a new ROM but then a few weeks later it returns... I realized that this only happens when I try to send an MMS message or attempt to receive them. I don't know how to stop receiving an MMS but just delete the picture message you're trying to send and your data should stop blinking on and off. Can't guarantee it'll work for you but it worked for me! GL!!
It appears as though this stupid annoying silly obnoxious bug has finally been squished, sprayed with 3 cans of Raid, and its' mangled corpse then burned to a crisp...I hope.
3 weeks ago W1ldFl0wer brought this fix to Albinoman's attention...
In the build.prop under phone>system was the following line....
ro.telephony.ril.v3=datacallapn,signalstrength
This line appeared like this on all AOSP roms for the sensation.
The fix was to add skipbrokendatacall to the line so it looked like this....
ro.telephony.ril.v3=datacallapn,signalstrength,skipbrokendatacall
Save the file, reboot, and data should spine right up and work fine. So far the peopl ewho have run into the data bug have implimented this change and BOOM, data fixed.
So if you use any AOSP ROM 4.0, 4.1, or 4.2 other than Albino's CM10.1 Kang just add skipbrokendatacall to that line and see if it fixes it. Only do this if you on in the US on T Mobile's network. If you are in parts of Europre making this change will screw up your data.
If you are using Albinoman's CM10.1 Kang ROM, he has already included this line in the build.prop for you. You just have to activate it. About 30 lines into the build.prop is the new line that reads...
#ro.telephony.ril.v3=datacallapn,signalstrength,skipbrokendatacall
Just delete the # in front of that line. (The # makes the ROM skip the line when loading everything, but lets it stay in the file so you can read it. Deleting the # means that the phone will read that line when it reboots.) Then go up to the line that says the same thing without skipbrokendatacall and delete that line entirely. Save the file and reboot. If you don't delete the original line without skipbrokendatacall, your phone will go haywire, data might not work at all, and you might inadvertantly trigger Z Day. So if you're not ready to fight in the zombie apocolypse, only leave one of those lines in the build.prop.
Hope this cures it for everyone! Again, don't make this change if you live outside the USA or are not on T Mobile's network! Doing so on other networks in other parts of the world could make things worse for your phone!
Here is the link to the post where W1ldFl0wer informed Albinoman of this fix.

I don't think W1ldFl0wer invented the fix, but he certainly is the one who made it public to Sensation users so go to that post and thank him/her bcause I might finally be able to stop obsessing over this stupid bug because of this user!!! :good:
Okay, so I flashed Paranoid Android 2.16. Everything went great, flashed fine. But I could not get wifi to work at all. It would turn of and back on randomly, would not connect to any network, etc. So, I flashed the ROM by Team Viper. Again, flashed fine, worked fine, but Wifi would not work, it would do the same thing.
So, then I restored my nandroid backup, and wifi works grand. Is there something I missed? Stock isn't too bad on this phone, but I'm a flash junkie, and I'll miss JB on my GNex. PA works beautifully, except for the damn wifi issue.
So, any suggestions on how to get wifi to work on my custom ROMs? Loving this phone so far, I've missed HTC. The three things that would make it my *perfect* phone is SD card slot, bigger battery, and 720p screen. But the phone is gorgeous and feels amazing physically and performance wise.
Same problem...

Okay, I'm glad that it's not just me. I'm going to try again, sometime tomorrow or later today. I'm hoping that it's something that can be fixed with a little more digging, or if it's something that we need a wifi module for.
Same thing here. Just fixed a soft brick now I got utb ROM working. Flashed trick droid and WiFi is gone.

Okay, there was another post with this issue, something that I missed. But apparently it's because of the last update (ICS 4.0.4 & Sense 4.1).
Flashing ROMs over this update seems to be breaking wifi. Here's the other post: http://forum.xda-developers.com/showthread.php?t=1913757
I'm having a lot of trouble with this as well. I just bought a One S a few days ago and got to work rooting, etc. After trying to install other ROMs, I can't get wifi to connect.
I have a T-Mobile version One S and can only assume it's gone through the latest updates prior to my purchase (got it through craigslist).
I have a decent idea of what I'm doing with these phones most of the time, but it seems like this time around I may need a little hand holding through the potential fixes. Like an idiot, I didn't bother to do a backup before jumping into flashing my first ROM, so I probably shouldn't be surprised that I'm having troubles.
Anyways, any help would be greatly appreciated. Right now I'm just stuck here.
What info do you need and how can I find it?
Extra info:
I did try the 1.84 and 2.35 partition fixes but still couldn't get the issue resolved.
Yeah.. I flashed the international version of trickdroid and my wifi signal was great, then I flashed the TMO version (I have a tmo one s) and it messed up my wifi signal completely, weird.
Have you guys found a way to fix it? Im having the same issues with all the custom roms, I've tried several of them and even different versions of the same rom(I thought it was an issues with that rom version) but the wifi never seems to work on any rom I flash. I'm using a htc vivid with att. If you found a fix could you pm me?
