Hi, I am canada, with fido/rogers and currently with the lastest 4.2.2 update and my signal is driving me crazy .
I've tried different radios using fastboot , but it is the same issue
it will be 5 bars than 3 than 0 than 1 than 2 etc
It can't hold a steady signal.
i've flashed the phone a few times to try to fix this issue with takju images and nothing
anyone else? is the phone bricked?
I found a rogers nandroid back up on these forums.. not sure if this will do anything
I'm on Bell and I have had a similar problem before. I wouldn't get good signal at all and the data speed was pathetic.
Try flashing the UILH1...it improves the signal a bit.
Hi. I recently bought (almost new) second hand N7105 and having really little troubles with it, one irritates me pretty much.
On are where Im living there is really good 4g and 3g signal. Everytime I reboot the phone and give pin, it goes for roaming mode for
aproximately 1 minute before getting to network. If its on 4g and I make a call or someone calls, it switches to 3g but after the call,
dont switch back to 4g.
When I switch it in network mode option, com.android.service crashes EVERY time. But it still switches it.
And when im in 3g mode it seems to prefer 3g more than H+ so like browsing on net it drops to 3g but when clicking a link etc.
phone does nothing before it has switched to H+.
I did call to customer service and they thought its maybe a update that didnt install correctly and adviced me to do factory reset.
That just made it worse. I really dont fancy to send it for repair since it seems to be only software problem but on other hand,
I dont wanna loose warranty by flashing custom rom at this point. Any advices or ideas?
Let me put it this way... What is the easiest way to install stock firmware without losing warranty?
And does it contain risks like changing imei?
Hi
(sorry for bad english)
I'm living in Persia, and I have a T-Mobile Galaxy S4 M919
MY Original ROM was MK2
I rooted my phone with this method :

I unlock my phone with this method and everything went very well.

(The antenna signal is always between 5 and 4, but the sound was good, as the case may be due to differences Frequency Band between T-Mobile and my Operator)

I updated My phone to NB4 ROM,and I noticed in Battery Graph the Mobile Network Signal is always black, except for the occasional bit of green. However, coverage is still good as before
I've read the black color means that the radio is turned off or disconnected. it's True?
Should I be worried about this ? , that case makes it use more battery? (always searching for a better signal)
Generally how reliable is the Mobile Network Signal?
I've tested the modem NH7 as well as NB4 and often Mobile Network Signal is black.
Now I've installed the modem MK2 in NB4-ROM, and the Mobile Network Signal mostly green. Photo is attached. (Antenna still vary between 4 and 5 ,and is acceptable)
The difference between modem and bootloader is causing the problem?
I have this problem only on Android 4.4 ,is this coming from Android 4.4 bugs , or difference band of my operator and T-Mobile ?
Friends: What is your suggestion?
Which is better? NB4 ROM with MK2 modem OR original NB4 and I do not notice the Mobile Network Signal?
Both GSM and 3G have this issues, But i use often GSM
Thanks in advance.:fingers-crossed:
It's normal, don't know if its a bug but it doesn't mean you had no signal or that its searching for a better signal.. I've had that since 4.3 or 4.4.2 can't remember exactly.. Just don't worry about it, if you lose signal it would have a red bar. Mobile network is just as dependable as it's always been, I've made calls and received notifications while showing black..
This is my graph with a little bit of black on full 4.4.4 firmware

It just doesn't display correctly I'm assuming.. Why don't you update to NH7?

'm not sure about upgrading to NH7 because i cannot downgrade if it has problem or etc . (and for root most use CF-Auto-Root and unlock boot-loader )
I hear some issues of NH7 and not want update at this time.
i stay in NB4 , unless Android 5 come for our device. or have major issues with this rom
but now i search to resolve this issues (Mobile Network Signal's Color is completely black in NB4 modem) and i hope i find solution.
difference between Bootloader and modem , May create a problem? if yes , In what context?
I have not problem with signal and could be a problem later?
thanks

People post they have problems with every firmware, but I never have problems, most of the problems are user error I'm sure.. It could be a bootloader mismatch issue, but like I said earlier, having a black bar doesn't affect signal or battery
I have purchase F240l from online store but i have serious signal reception issues with this mobile.
1- In outdoor Network reception is around 5-10 dbm less than other mobiles. But the real problem comes when i am in low signal areas. This phone will disconnect all of sudden after -95dbm. while other mobiles are still locked to network.
2- The wifi reception is poor as compared to other phones.
3- The GPS never locks. in GPS test it shows 28 satellites in view as soon as GPS test is started but actually all signals remain at zero and in view satellites also remain to zero.
I want to know if this problem is related to hardware or software.
Also if you guys can suggest some solution to this problem from your experience it will be very helpful.
Note: I have reflashed stock jellybean and kitkat roms by lg flash tool but there is no change in situation.
Replace the build.prop

You should try this Method.
This might solve your problem. You should backup your original build.prop in case things goes wrong, also make a Nandroid backup.
Btw it didn't work for me actually 'cause I had other radio issues with my phone.
All the credit goes to Akhtar Ali Jatt... Thanks him if it works.
I was already on custom build.prop to get rid of the Korean rom problems.
Yesterday i also installed Sphinx 3.0 which is supposed to have better signal strength.
But all of this did not work.
I want to know if other f240l users have same problem because it is not optimized for international use.
Or this problem is specific for my phone.
For hardware issue, i improved the antenna connections with pcb but still no change.

Many users have the same problem so there's nothing you can do to get better wifi signal.
Ps: my F240L is also has very weak wifi signal.
Any news about this issue? I have F240L with weak WIFI and GSM signal.

Guys, unfortunately i have this same problem. My only option was just use the 3G signal (selecting on network settings). Its been passed 5 months and i still dont know how to fixed. I tried every ******* thing and the problem remains, at least choosing the 3g signal i can use my phone as a phone !!
obs: the problem started after updating to original MM.
I also have this issue, or similar.
Mine occurs when i connect to wifi whilst using 4g. If the 4g signal drops it wont automatically switch down to 3g. I have to do it manually , by changing to 2g/3g in network settings. auto/2g/3g/4g works fine whilst not connected to wifi though.
Mine seemed to start doing this when i first flashed MM or Fulmics.
I have tried flashing old radios, doing a complete unroot factory stock kds flash but nothing has fixed the issue.
Anyone any pointers or an explanation as to what could have possibly happened?
Cheers all
I had the same problem.
I flashed RPM and correct modem.
No signal drop anymore but no LTE.
Flashed modem again and RRom and it works perfect now!
I guess I should flashed the modem twice at the beginning.
