No Signal !

: Hi guys, I have been having this issue with my dash, most of the time its saying "searching" and I cannot get any signal, I have flashed different ROMS and none of them seem to be solving the problem, sometimes it switches to "phone off" by itself, and then it continues between 2 bars of signal and "searching" and I know its not the service because when I switch to my RAZR it works just fine, any suggestions please?

This may or may not help, but to eliminate all variables I would suggest trying a new sim card just for kicks. I know that it works in your RAZR, but the smart phones are a little touchier with older version sims; especially if there are any divits, scratches, or obviously any build up on them. The latest TMO Series 3 sims look like a globe (the gold contact area).
I can't tell from your sig what country you are in or what provider you have, but if you are with TMO US they will swap it out for free at any corporate store; at least ours does. Besides it never hurts to have the newest version anyways.

also if you're on tmo, you can check on their site the coverage area, and see if you're on a bad part of their network.

Can't turn Desire on from standby

Hey.
I have a big problem with my desire. The phone is fully working, but when it goes into standby, and I try to turn it on using the "power button" at the top, the keys light up, but nothing comes on the screen It just doesn't turn on again.
Any ideas? Thanks!

In the general section on the desire forum there is a topic related to defective proximity sensor. i,m a new forum-user so i can't make a link yet

Thanks for the help so far, but couldn't find anything that solved my problem :/ Have to restart the phone every time it goes into standby

Like many others, I am also experiencing this standby-of-death (SOD) problem: the lights in the buttons under the screen turn on, but the screen itself stays black. I have found out that it has to do with switching from 3G to 2G networks: the problem occurs after I have been at places where there is no 3G signal, but only 2G. For example, after a car trip or when going into the basement.
A workaround for this problem, is to type the code *#*#4636#*#* in the dialer. You will then end up in a hidden menu. By choosing "Phone information" (first item) and then scrolling down in the next screen, you can change the "Preferred network type". By default, it was set to "WCDMA preferred" on my phone. After I changed this setting to "WCDMA only" (so, 3G only), I have not seen the SOD issue anymore (for 4 weeks now, before it happened almost daily).
A disadvantage of this workaround is that the phone will never use 2G anymore. So, when you are at a place where there is no 3G signal, you will be disconnected (i.e. you cannot receive phone calls). As an alternative, I have now reverted the setting to the original value ("WCDMA preferred") and I have installed an older radio image (version 32.44.00.32U_5.09.05.30_2), which is considered to be more stable by many people. I'll test and see whether the problem reoccurs. If the problem stays away, it is apparently a software (radio image) issue. If not, it must be a hardware issue.
Anyway, if anyone has additional information about the root cause of this standby issue, please let me know!

OMG I love you!
Seriously this has been doing my head in for weeks! I have posted a couple of times in this forum. First time, constantly remvoing and replacing the battery left me with a bricked phone. HTC revived it under warranty but after a week I got sick of Sense (and the poor battery life) and tried rooting again (tried Redux and CM7) but the problem came back. Makes sense because it works fine around Bristol (loads of 3G) but constantly SODs in Bournemouth (flicks between 2G and 3G at my desk). Also, just had data off for a few hours and didn't get SOD once.
I am not up on the lingo yet as I am fairly new to rooting but running Baseband version 32.49.00.32H_5.11.05.27. Is this the radio?
Please keep me posted on the older radio version. Shouldn't need a long test period, just need to go from a known 3G area to a known 2G area while locked.

Baseband version 32.49.00.32H_5.11.05.27. Is this the radio?
Click to expand...

Yes it is the radio.
I have got GingerVillain (Based on CM) and I use the Power Control widget to switch between 2G and 3G. You can customise the widget (just add it to a screen) to get this feature.
I haven't got any 3G around my house so I don't need to activate it all the time .

Yeah Redux has a similar thing so I will use that until a proper solution is found.

Small update: enabling 2G only didn't fix the issue (I think 3G only is okay) so perhaps the issue is with 2G rather than switching between the two.
Instead I am using an app called "3G Data Only!" so that 2G can still be used for calls but not data, working great so far.

I have tied the latest Radio (32.56.00.32U_5.17.05.23) and the problem does not go away.

How come this problem doesn't occur to (many) others? Could it be related to your network provider? Maybe you could change the SIM with another, from another network, and see what happens. Also, you could make use of the phone warranty - if it's still covered by it.

On o2 (in UK) right now, will try out another sim later. As for warranty, never had any issues on non-root Froyo Sense so can't do anything.

Try to change the network, say, from O2 to 3 or Vodafone. If your Desire is branded, there is a free way to unlock it - just look for Desire SIM-Unlock utility in the forum, by sieempi

Been running radio 32.44.00.32U_5.09.05.30_2 for a couple of days now and the issue seems to have gone away.

I also have this SOD issue with the older radio ROM versions, so installing an older version is not a solution.

I can confirm that. I have tried most of the radios listed here and here, they all have the SOD issue.

Great, I'll try this application! Would be very nice if that fixes the problem without disabling 2G phone calls. I never use 2G for data (too slow anyway), but I would like to be able to still make phone calls when out of range of 3G cells.

It might be, I don't know. I'm using a Telfort SIM, connected via the KPN network (Netherlands).

3G data only works a treat for that, you can make calls.
Found with the old radio that it is a lot more stable than the new radio but not 100% perfect. Where I work I only have 2G and it would SOD all the time but now it doesn't. However on a journey I make with intermittent 2G/3G I did get a SOD.
Sent from my HTC Desire using XDA App

3G Data Only doesn't work well enough. The SOD issue does occur less frequently, but the phone still hangs sporadically. So, if have disabled 2G completely again.

You should try Insertcoin. I haven't had this issue since I started using IC v32 a2sd.

Hi there. So i get the same thing on mine. I thought I should report my experience.
Had it over a year old then all of a sudden it started acting like this
heres what i tried
Factory reset, rooted it twice, boot with no sim, no SD card, dismantled it via instructions I found on an android forum to check for loose connections, gave it to a friend who ran some different roms, overclocked it, underclocked it. Its currently on the Oxygen rom, no difference. I tried the secret menu from page one of the comments. I tried living with leaving the screen on for 30 mins..but its so impractical
I should add that if i leave it for say a couple of hours, the damn thing comes on just fine. Its only from being on, to off, then back on..
I think its hardware related, maybe something to do with the power being held back for the screen or something. All i can say is that its really doing my tits in and i'm currently using my old phone which is functional but not as fun.
What can i do next...send to HTC, i'm out of warranty but their repair centre can still have a look, or buy a faulty phone off ebay and harvest some parts...
I dont want to give up on it, because apart from this the phone works fine.

guys i had this problem too, when i force to use 3G only everything works perfect but in area with no 3G signal your phone become useless cuz you are out of network, i also had a self-rebboting problem and i sent my lovely desire to htc repair center, they replace mobo and now i am waiting to receive my phone back and i will test this issue, if everything will works correctly in 3g/gsm etc you guys need to do the same and sent your phone to repair,

A few questions about the GNex - Network, Mail etc.,

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

Why data connection lost and why reboot fixed it?

Hi,
Using GNex, stock JB 4.11, Wind Mobile Canada, $40 plan, unlimited data & Canada wide.
Please excuse in advance for the novice questions. I am not yet familiar with Wind Mobile. The customer support is too long and submitting a question to their website required around 5 days to get an answer which is generally irrelevant in my short experience. Hope some expert users here can share some of your knowledge.
Last week, suddenly during a phone conversation, the phone became totally disconnected voice & data. The next morning, the situation didn't improve, so I rebooted the phone (power off / on). Then the phone could connect to voice, but no data (gray icon instead of blue). I stayed with no data for 3 days. During that time, I tried a few reboots, changing various network settings (APN, Network Operators, Data roaming, etc.). None of that worked, then I made another reboot and suddenly everything is back to normal (no roaming and data OK).
Q1. Signal strength variation: what is the cause that makes a signal vary? For the same location, sometimes signal changes from 3 bars to 1 within a few minutes.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data). I purposely disabled roaming, I admit a network could have some issues, but I have hard time to admit that a disruption could last 12 hours. May be the issue is my phone? It was not rebooted since 7 days.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Thanks in advance for any help.

Welcome to the Nexus and its crap radio. Try turning off 4G, once I did that I never lost signal again. With 4G on I get disconnected from the network randomly throughout the day

How to turn off 4G? Wind Mobile operates on AWS network 1700/2100 MHz (UMTS band 4), and HSPA+ for data. I believe it is not 4G. On the phone Network Settings, there is only an option "Use only 2G Network" which is not a good option for me. If I enabled "Use only 2G Network" the phone shuts off data and changes to roaming mode.

just set ur nexus on airplane mode for a second..
then disable the airplane mode instantly..
u ll gain ur net working widout reboot... )

Any number of influences. A microwave, air ionization, temperature, humidity, output from the tower not consistant, and plus just the variations of the phone. Going by bars is a bad way to gauge anyways, it could have only dropped signal for a split second but it doesnt update the bars frequently so it would appear to be low signal longer than it could have actually been. Your phone works by line of sight, picture a tight wire from your phone to the tower, anything that crosses in that line reduces signal.
Q2. What caused a network to black out temporarily? That's what I got last week during the entire night. The reception icon is a black outline triangle (no voice, no data).

It was not rebooted since 7 days.
That actually is hard to answer, you would need to contact your provider to see if they have a log of an outage at that time before going into whether it was the phone or not.
Q3. How often should I reboot the phone? By reboot, I mean power off/on. I hope this is the correct term. Is it possible that a frequent reboot help the phone to be more responsive? I tend to think so because all the network issues I got were magically fixed by reboot.
Never unless things act funny. A reboot is usually healthy for operating systems (i know many do not). I personally don't intentionally reboot mine, it usually happens because I'm screwing with clock speeds
Q4. Why would a reboot fix a data connection issue? In my case, a few reboots on day 1 didn't fix. Many network settings changes didn't reconnect data. Then finally another reboot on day 3 fixed data connection.
Like any software there are chance of a 'glitch' where the modem and the driver have issues communicating. Toggling airplane mode off and then back on re-initializes this and in most cases fixes the communication problem. Rebooting will have the same effect. I would only worry if you are needing to do this often.

Hope this helps a little.
I would also contact your provider. They may have an issue with the tower you are connecting to.

Perfectly understood, appreciated very much your detailed answers. Can you please clarify below?

Makes sense. Indeed, when I said "For the same location, sometimes signal changes from 3 bars to 1 within a few minutes". Actually, I mean a room and I was walking/moving so may be the orientation of the phone explained why the reception was inconstant.
Regarding your answer above output from the tower not consistant. Is it possible that the tower reduces its signal strength when the number of users increases? Similar to users sharing a finite band width?

Yes, even orientation of the phone can have an affect, depends how the antenna is set up inside the phone, i havent seen it so i have no answer for that.
ya, as you move around you could have been what blocked the direct sight of the tower, signal passes through nonmetal objects but each time it does, it loses strength depending what it passes through

@OP I also have the same problem, I am also with Wind and had to do force reboot to make it reboot.

Flash the UGLC1 radio to your nexus. I'm with Wind as well and that radio gets me good service!

H812 Keeps Losing Signal (Please Help)

Hello everyone, I've been lurking here all weekend as I've been trying to stabalize this phone I bought off of Kijiji. Right off the bat, when I
installed the sim I forgot to turn off the phone . Haha, I was extremely tired & only when I removed the battery (of course) did I realize what
had happened. Ever since the sim has been in, the signal has been unstable every 5-10-15 to 30 minutes (this is without running POGO). By
unstable, I mean both data & most importantly calls. I won't be able to make or receive, when I place the call during these failures it will
say dialing, connecting... and just continue until "call ended". And when I"m called, outside of LTE just say we've forwarded your call to VM. On
LTE, it will say something along the lines of this customer isn't able to receive your call at the moment.
Troubleshooting Attempts:
- Tried SIM in a different phone & it worked perfectly
- Power Cycled Several times, Factory reset it 3 times
- Set up 2 APN's (sorry can't link yet, but google them if u like they're ez to find. LG G4 VM Canada APN's)
- ^ Tried both, both unstable, but PDA gives most stability
- I've registered to all available networks under GSM/HSPA/LTE all unstable
- Connected Automatically & Manually to GSM/HSPA/LTE together & separately. All unstable
- Phone is not in Air Plane mode
Model: LGH812
Unlocked, Original Carrier: Rogers
Current Carrier: Virgin Mobile (Canada)
Android OS: Marshmallow
Kernal Version: 3.10.84
Build Number: MRA58K
Software Version: H81220x
Now, I have just recently come across a very interesting development. Using the App Network Signal Refresh Lite,
In pokemon go I've been able to transition to a signal that will stay solid for up to 5 minutes, 3 on average. It will still
lose connection, but will usually reconnect in-app in moments. I do have to minimize it & do a refresh again in NSRL
every now and then but it's a big improvement. Before hand, when I would use go, the service (calls included) would
completely rip in seconds.
So... any ideas? I'll appreciate any & all help.

I've flashed every stock rom I can for the device too, but the signal continues to drop regardless of the OS. Some error messages I' ve gotten are emergency calls only, no service & service disabled but usually it just shows that its connected to virgin but I can't make or receive calls.
Other than the cellular service, everything else with the phone works perfectly. The wifi, the camera, the gps, etc it would be a shame to have to get rid of it but the essentials first. I have to be able to make calls.
Please, anyone, any ideas? Are there any apps I can install to fix the broadband or something.

It won't remain stable no matter what I do... and no one has any solutions
tips, thoughts or ideas? Really regretting this purchase now... It's been a
month and I still cannot get a stable connection. This is ridiculous.

You may want to check out this link (https://lg-firmwares.com/lg-h812-firmwares/) for an H81220X Bell/Virgin kdz (H81220x_00_1122.kdz) and use LGUP-NEW to install it. It might help but if not, you may be facing a hardware issue ...

Solved lg g4 losing signal
I bought my lg g4 K450 and within days l noticed my phone was losing signal constantly. By the grace of God l tried this and it worked.
Go to settings---Then to Network---To more---To Mobile networks----To network operators. Select search network. All available networks will be displayed after a thorough scan. Select your network provider with a WCDMA instead of GSM and it will register it. After it done registering, restart the phone. and u are good to go. It worked for me, if it works for u give glory to God.
