[Q]how do i fix low signal TB stock radio with CM7 - Thunderbolt General

Good Afternoon all:
Im running a stock radio, CM7 on TB. My Signal is on 1 bar no matter what location I am at. I tested the signal using a signal app and it confirms that i have a low signal.
Is there a kernal that will fix this? I did some searches but could not find an answer to my issue.

No, CM7 is still a pre-alpha, and 1 bar doesn't mean anything, when I use it with 4G it shows no bars. What is your network signal strength in Dbm?

im running about -90 dbh. sorry, i should have put that in my first post. what do you think on the cell strength?

i put cm7 on my phone with the stock radio, and had ZERO bars lol
until a call came in , then i'd have a few bars
no market access, no data connection...

i dont know if this has already been said or fixed but i am getting 4G with CM7. i have no idea what i did... but it seems to be working

Any way to increase the radio signal strength

My signal strength isn't the best, coming from a droid x I'm spoiled.does anyone have a fix or know if an update will fix radio issues and 3g or 4g from dropping.

You can download and flash the latest EP1W modems here.
Also you can check out the 3g Turbocharger script here.
All the info you need is either in there or linked accordingly. Be sure to read everything in full.
You could always try flashing the Ep1w radio and see if that helps. I personally have not had any signal issues. At home I get full service while my gf sitting next to me has to contort herself in some pretty freakish fashions to get even one bar of service on her Dinc2. I would say the stock radios are pretty good on these phones.

That 3G turbocharger script will likely do nothing for the 1X/3G connection, and in reality, it does nothing for signal strength. It is meant for GSM networks, and can potentially improve you up/down data speed. The best you can hope for when using it is a faster 4G connection.

Poor signal

I got my NS4G a few days ago..n my signal strength sucks!!..i know i get good service in my area n at home cuz my girl also has sprint..so my question is is there anything i can do to fix this...im on 2.3.7

[Q] Can a ROM effect calls (that is - dropping them)?

Hi
Just wanted to know.... since I am dropping calls so often, can that be ROM-related? Or does that have nothing to do with that?
Because if there is even a slight chance that it is ROM-related, than I will go back to STOCK
Running WeaponG2x right now
I have had signal problems on every Rom I've tried.

Doesn't this make you want to sell this phone and get a different one?
I found that cm7 based roms seemed to not switch towers as quickly as stock roms.might just be my device though. I get notably fewer dropped data connections on tsugi.

Me too.
Yes, but I broke my screen and have been too poor to fix it to resell. LoL
I have had the same experience so far.
I've not had any dropped calls on any roms I've tried. Currently on Tsugi and even wifi calling is working.
My signal everywhere but home is at least 3/4 bars and I always have 4g speeds >3mbps down.
I live in central Florida, Polk County.
The G2X just seems to be a little bit less robust in low signal situations.... so you will only have a problem in marginal areas usually...
Now I just discovered something odd with mine... If I set to WCDMA only, and force 4G signal, I don't seem to lose signal at all in my apartment. When I had it on WCDMA preferred, it would constantly switch between 4G and 2G modes, and I'd lose signal frequently, even if I was on a call... so it seems to me the problem may actually be in the switching between GSM and WCDMA.... Or just with GSM... need to do further experimentation.
I live in the middle of Orlando, so I really don't think that's considered a marginal area for a signal. Tmo said there was a tower not that far from my house too. I'll have to try the forcing it to 4g next time I am out and about and see how that works... Thanks for the suggestion lotherius.

[Q] 4G symbol with no bars?

Hey guys I just recently got a samsung t959v as a replacement to my nexus one that got its screen cracked. So far I am loving the phone and had no problems with it. I recently updated it using the Kies mini software and updated the phone to 2.3.6. After updating, I rooted the phone using superoneclick and everything worked out perfectly. The only thing I have noticed is that my signal bars are now always empty. I have the 4G symbol on green, however the bars next to it have not turned green at all. I am signed in to google talk so I know it is not the grey/green signal issue. Before updating and rooting I always had FULL 4G signal here throughout my apartment and throughout the city. Anyone know what the problem could be? Everything seems to be working fine using the network however it is just a little annoying not knowing how strong the signal really is. Any help would be greatly appreciated. Oh and I also installed setcpu and changed some of the settings, not sure if that has anything to do with this issue....
4g and"the bars" are two different signals. Cell it's used for calls when not connect to wifi and for SMS. 4g is your data: internet,g talk, market, and most everything else. if your not experiencing issues I wouldn't worry about it. Set ovum doesn't have anything to do with this but here we have found tegrak paid to be more stable for oc/uv.

that is a UI bug with the stock firmware.
Don't worry.
Flash AOSP style. It will remind you of the N1!
Leave your battery out for 10min and try again
DON'T FORGET TO THANK!!!

Kernel And radio Combo Question......

Whats the best Kernel to use with the i727UVLE1 radio? Im on stock 4.0.4. Using T Mobile on my Unlocked Skyrocket. Im trying to get better signal bars. Mine is 1 to zero most of the time.
Just wondering...does different ROMS help increase the bars? If so...whats the best combination that somehone has while having 3 or more bars of signal constantly.
By the way..mine is showing 3.0.8 in the about phone.
Kernels and roms don't increase signal strength that has has to do with the radio.

Man...what can i do to increase my signal bar if you know? I see the 4G...but 1 or zero bars. I did a reformat 2 hours ago thru odin. It had the wrong radio because i had no 4G or edge...BUT...the signal bar was all the way FULL. In my room..where its never full. That makes me thing my room IS capable of getting the signal. But what can i do...tweak wise...to get the bars high?

I tried the Blaze...which people say is the best. Gave me 4G...but 1 bar of signal. Then now i have the i727UVLE1....4G...but 1..maybe sometimes 2 to zero bars of signal. I mean...there has to be some tweaks that i dont know about. In the settings or anything. Ive only tried those 2. I see a KiD radio....same base..T989...isnt it all the same...just different people uploading em?

I'm not sure if they're different. The area youre in may not have great coverage. Ummmm you could try some other T-Mobile apns if there are any. Not sure since I don't use mine with tmo.

It has to have good coverage. When i put this sim card into my old Slide phone right now...i get 4 or 5 bars. With a 3G symbol. Also...when i factory reset my skyrocket a few hours ago...all my bars were FULL. I mean perfect...but no 4G. Because the radio was wrong. So when i put the radio i had in it before....4G came back...but so did the suck signal with 1 bar. So i know this area CAN get good signal. I need to know what some people on here are doing to get it. What combinations to use and stuff. Im on stock 4.0.4.
Can this ROM:
http://forum.xda-developers.com/showthread.php?t=1763195
[ROM]SKY-ICS 4.2F6-2.5 (8/2) (UCLF6 Base) AT&T-OFFICIAL ICS.PROJ MARGARINE, W/ G-NOW be used on my skyrocket unlocked to T mobile? Or is this radio in here NOT for T Mobile?
[Edit] See,,right now this second...i just installed the 4.0.4 tar again from odin. It has 5 strong bars of signal right now. But no 4G. meaning the radio in there is wrong. Its showing i727UCLF6. Which is (I think) the AT &T radio. I have a T Mobile sim in it unlocked with TMO. Any radio i add from here...will make my signal go down to 1 bar. BUT...it has 5 strong bars now. Man..wish there was a way to keep those bars.
Sounds like you're in a good 3G area...but only borderline 4G area.
I travel constantly & have encountered this many times.
So..shouldnt i at least have bars with a H or something? Bars are 1 or none. Weird. I flashed thru odin 1 hour ago. Got done...5 bars strong. Filled. But no 4G or data. Had put in the right radio. When i did....4G and data came back...bars gone.

Can you share what rom and kernel you are also using.
I experience the same issues as DJR0D. The blaze radio gets me worse signal, I lose about 4 bars. This was with sky ics and stock kernel.
Right now I am back to the att modem since I need good call quality. It might be a placebo, but I think the calls sound worse with the blaze modem.
No one can help you pick a modem. Its relative to area and device. Flash compatible modems until you get the "best" one for you. Locked
