Hi Guys !! I currently own an optimus one running on stock froyo 2.2.2 (unrooted). Quite a few times (including today) I noticed that the icon showing signal strength in the notification bar blinking. Whenever I return from my college to home via bus..I find the signal strngth changed to null. At college signal strength would be like( 3 out of 4 bars) but at home it stays at full strength. But the day I go to college and return home ..on the way i find my signal strength on the top most notification changing to null for 2 seconds & then returning to full..again going back to its previous state & returns full & again....(fluctuation takes place aft 2 seconds each). Even after I return home where signal strength is supposedly full...the problem does not vanish unless & until I restart the phone. after restarting it doesn't fluctuate anymore. Why does this happen & how to get rid of this ? Pls note- I am on Airtel 2G network with network mode- GSM only. As most Indian users know airtel network is superb !! & I too stay in the capital city of my state so there's no chance of poor signal. i think it's a hardware issue. what u guys say ?
1 more query- can someone provide me the download link to android 2.2 firmware for indian optimus one. I found all the download links to have got expired except for 2.2.2 (v10d). main reason to downgrade-to be able to run ndrive on my phone. pls note that ndrive doesn't work on other optimus one's which come with android 2.2.2 preinstalled.
I wonder....
Airtel's signals are very strong even in the remote areas...
i dont think your hardware causes you this problem it could be your sim card
try changing your sim card and if necessary change your number as you say you wanna be on airtel so buy an another airtel sim and try your luck
or else borrow a airtel sim from your friend and check if its working for you...
If not switch on to vodafone as i did
I was also encountering some problems like gps can locate me.
So i switched.
Vodafone is also good if u try.
sure. thanx 4 replying
Hi all.
ive been floating around the forums for some time as an unregistered user but i now have to resort to posting for help.
fist of all heres my details
Android version 4.0.3
Baseband 19100XXLPQ
Kernel 19100XXLPQ
Build IML74k.XXLPQ
ok so first of all id like to know if it matters that the serial on the phone does not match that on the sticker behind the battery although the IMEI number does,from what ive read on the forums this may be because i flashed a non official ROM?
when i originally flashed to ICS the signal was poor but i still used the phone and now i have no signal at all at home,
if i try and dial a number i either get `mobile network not available or not registered with network.
ive flashed the phone with so many roms,kernels and modems now that im in a complete mess with what ive actually done.
i checked with my provider `3 UK` if the phone was/is blacklisted but its not,ive had the sim replaced with a new one and also tried another 3 payg sim.
im not normally one to give up but i admit im getting close to it.
in hind sight i wish id taken a full back up whilst on gingerbread or even never upgraded to ICS in the first place ..ah well
so my thanks in advance if someone can help me and apologies in advance also if ive missed any information out.
cheers

just to add to this,
i just stood outside and scanned for networks,the 3 network appeared but when i select it it says:
your sim card does not allow a connection to this network
i spoke to 3 just incase its their end but they insist its nothing to do with their sim and is my phone thats the problem.
this is a sim only contract by the way the phone did not come from 3.
so u hav no signal??
imei may got reseted..
flash stock rom an c....
jus my sugettion wen in xda don float get registered
i have no signal or at best its extremely poor,just enough to scan for a network.
what do you mean imei may have been reset? the imei is the same as it was originally.
and ive flashed lots of stock roms and had no luck as of yet.
just tried android 2.3.5
Baseband 19100XXKI4
Kernel 19100XXKI4
Build gingernuts XXKI$
and its exactly the same :S

Should be on xda I9100_radio_NELP2_CWM

Clean Slate for those that balls up the firmware .Or need to return to service or decide if its hardware/firmware problem .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .

I meant have you entered the networks settings as supplied by 3 or are you hoping its auto set up after multiple flashing you may have wrong CSC .
jje
so is ur prblm solved did u enter settings as jje said,,,,if ur phone is working fine now,then post
no my problem is not solved however i have some updates after driving around the area (going to the pub)
ive not changed any network setting as i see nothing there to change.
i managed to get a few signal bars and searched for available networks,3 was ther,when i selected it i got this message:
unable to change networks while data service is in use.stop using current data service and select another available network?
i said ` ok`
...registering on 3...
...registered on 3 network.
after this i was able to make a call.
i noted some info at this point incase it has any relevance :
Signal bars: 2
signal strength -109 dbm 2 asu
Mobile network type:9
service state: in service
network:3
phone number : unknown
this happened in one spot on a 1 mile journey.
and now im back at home the signal is back to nothing.
the 3 signal in this area is normally pretty good so something isnt right
the info now is:
Signal bars 0 - 1
signal strength -111 1 asu
Mobile network type: unknown:0
network: unknown
service state: out of service
mobile number:unknown
ive always had a good signal at home and for all of the journey i just made but now it seems to only pick up in a very limited spot.
ive not entered any network settings at all,like i said theres not much i can see that needs changing?
thanks for your input guys its really appreciated.
I don't know if its your issue,but I had several phones on 3 which all had awful signal strength- I just changed to a different network.
Sent from my GT-I9100 using XDA
3 isnt the problem here,everything was fine until i started fixing things that arent broke, and im old enough to know better :S
ive been with 3 for as long as i can remember with lots of different phones and never had any signal problems where i live up until now.
still unsolved
Weird. I have exactly the same problem. except Im on irish network meteor. same symptoms. ben on ics for ages, flashed a cm9 rom. nothing unusual,bam. no signal or very little.
try flashing NEKF2 or NELP3 modem
I have issues with 3 UK too, mainly because I like having the option to switch back to 2G to 3G to H, but 3 doesn't like the idea of GPRS so that's out the equation Plus, the network is pretty piss poor. I'm looking for a better modem, in all hope.
Baseband: XXLPW. Running ICS 4.0.3
Hi to all.
I put Cofface's cyano into my Redmi 3 a week ago and it worked fine except for the network signal that seemed to me to be weaker than on stable or dev miui rom. Yesterday I don't know what i did, i just switched the network type from the services menu (*#*#4636#*#*) to see the signal strenght of 2g/3g/4g and after doing that, the phone stopped to take signal with my SIM in any network type. So i switched back through MiFlash (and selected flash all option), to the Dev and also to the stable rom, but now I just have 4G working.
I tried to put again CM and i get no signal in every network type, even trying to restore a nandroid backup that i made when the phone worked. I also tried to flash through fastboot the NON-HSLO.bin took from developer rom, but nothing changed. What could it be? Where I live the 4G is not everywhere so most of the time I'll be without signal and it would be really frustrating.
I tried my sim in a Samsung phone and it takes both 2g/3g (the phone doesn't have 4g) , but trying another sim in my phone (of the same carrier) gives me the same result of above : only 4g . While on CM that sim could connect (only 4g) but mine not.
Please help me! :crying:
sorry if i didn't explain myself well, but I'm not english
EDIT: with the 4G i can only surf on the net but i can't make or receive phone calls. I'm giving up on this phone
EDIT2: following some guides I erased modemst1 and modemst2 but now I'm unable to get IMEI and I have unknown baseband
I have the same problem as you (almost)
http://forum.xda-developers.com/redmi-3/help/cellular-network-redmi-3-t3370459
I also have poor reception and can't make any call or receive them on any band 2g/3g/4g and i have this problem since I received the phone.
Did you fix your problem??
I have the same problem of very bad cellular signals.
with the same carrier, when other phones 2 samsung, 1 chinese (cheap unbranded), one very old nokia all have good reception, xiaomi redmi 3 pro is inaccessible from other phones.
today I'll try to install some signal booster apps from thestreet.com/story/11733410/1/7-apps-that-improve-smartphone-reception.html hopping for the best.
if anyone find any solution please update
Hello,
Ive been facing some network issues on my new OP3 (bought 1 month back)
The phone didnt have any problem at all till yesterday when there was a sudden loss of signals in both my airtel SIMS.
OP3 is recognizing the SIM cards but doesnt show any signal. I tried swapping SIMS, my SIMS are working in other phones whereas other SIMS still dont show signal in mine.
However there were 2 instances where i regained signal and was able to make calls while is was at a particular location, but even that lasted for just 20-30 min.
I was using android vers 3.2.4 when this problem happened, tried updating to 3.2.7 (latest) but it still hasnt fixed the issue.
Thought it was a null IMEI problem, but Settings show IMEI nos. of both the SIMS
Tried manually selecting networks, mostly it says cannot connect...sometimes it doesnt do anything
Tried changing preferred networks in *#*#4636#*#* , hasnt helped either
And yes I tried soft and hard resetting too, hasnt helped.
Please do suggest any probable solutions.... Thanks You
Hello Guys does anyone experienced this?
Ive been using network signal guru for 3months to lock lte band 1, Then one night my phone suddenly lost its network signal.
whenever i lock it in lte band 1 or put on 2g only networks it just dont work. No network signal at all.
I dont have problem with Baseband and imei its still there i just dont know what goes wrong.
Solution i tried
Factory reset
Flash new rom (xiaomi.eu miui12)
Restore EFS (via twrp)
Still no luck. Is there any other solution? Or it might be a hardware issue i think?
Tnx
