Hi guys,
ok... I have an HTC desire... originally on Virgin Mobile and now unlocked. I'm an O2 customer...
I have rooted and installed the Leedroid rom... originally at version 1.8b. Everything was fine.... until I had a corruption on the SD card.... which I fixed when I got a second following a couple of days of "mounted read only." A day or so later, I lost connection to the O2 network and have been unable to regain it, despite several ROM (I'm now running Leedroid 1.9) and radio reflashes.
I still have access to wi-fi, gps etc.
I have tested my sim card in another phone (all ok) as well as other sim cards in my phone (doesn't work.) I have also swapped and tried another O2 sim.
The phone detects all the major networks... just won't let me connect.
The error message I get when trying to connect to a network manually is "your sim card does not allow a connection to this network"
I've obviously checked that the phone isn't IMEI blocked etc. I've also tried the sim unlock from the fastboot menu, the switching on and off of the radio, airplane mode... lots and lots of stuff.
I really am at my wits end with this issue. I love the desire... but it's obviously of no use to me without the phone element!!!
Can anyone please suggest something to solve this problem???? Could the corruption of the sd card have caused this in some way, despite several rom/radio reflashes since? I really want to stick with the desire, but at the moment I effectively have a £400 brick....
Thanks in advance for any help you might be able to provide.....

Firstly this is not a development issue, its a question.....
But anyway, when the phone is telling you that you cannot connect to the network is it allowing you to enter an unlock code at all? Or have you ever "unlocked" the phone in the past?
You're right Lenny... apologies for creating the thread in the wrong part of the forum.... perhaps a mod could move it....
Yes... the phone was unlocked from Virgin mobile prior to me buying it [from ebay.] I didn't perceive this to be an issue, given that I actually had connection to O2 for a day or two before losing it...
No... the phone/sim is not asking for a code when I attempt to connect.
Thanks,
Shep

and did it stop letting you on randomly, or did you do something immediately before?
Nope... completely random. I was in a poor reception area and initially put it down to this... but then it never returned and I'm now back at home having had zero connection for a week.
I think that my repair of the SD card was after I initially lost connection. But as I said, I'm not sure whether the SD card corruption is a red herring.
Call me sceptical, but I doubt you would of been able to check whether it was on the IMEI blacklist or not unless you worked for a phone network.
It's not public knowledge and someone working for O2 shouldn't have told you if it was or wasn't.
Also, even if they did and the IMEI listed on the handset is NOT blacklisted, as was possible with WinMo devices, you may have unintentionally changed the recorded IMEI on the handset to one that IS blacklisted - unlikely though I'll admit.

the sd card should not have anything to do with radio.
Go to dialer and dial *#*#4636#*#*
then press phone info
done.... what info do i need to post?

try to go down the bottom and press the "turn radio off" button
then when its turned off try to turn it back on, then see what happens.
Just done it and no changes.
Did it several times between reflashes too... not so much as a flicker...
No idea then, unless the IMEI has been blacklisted.
Ok.... thanks anyway.
Any luck getting this to work? Am in the same situation - t-Mobile unlocked Desire with a 3 SIM?
Edit: I have intermittent reception/connection to 3 now - I did a lot of recovering/trying RUUs which would partially load on Win 7 then just disappear...assume they should have done something more than that. What seems to have helped - and I partially had this problem in my Nokia E65 - was to place a piece of paper (SIM sized) behind the SIM to 'push' it onto the contacts. Well, maybe it was a software issus but it's now my luck paper and I'm not removing it!
Gone again. Very annoying.
RUU'd to RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed (unbranded 2.2) and still no luck.
Any ideas?
Hello all,
my Defy is stuck in emergency mode and can't find my carrier anymore (o2). Details:
- only emergency calls possible, no network found
- another mobile in my house gets outstanding connection (o2 aswell), when switching SIMs, it's still my Defy not getting a connection
- wiping the Defy has not changed anything, even with stock settings all I see is the red cross (put my settings back with clockwork recovery)
- an hour or two before this happened I was listening to music with my headphones, but between taking the headphones out and GSM failing I was sending texts
- When doing a search for other carriers I can see some (though not reliably), but not mine
- I bought my Defy via Amazon, so no SIMlock, obviously.
- WiFi, Bluetooth and GPS are all working fine, so they probably have different antennae
- I rooted my Defy, but this was over a month ago, and it was working fine. I also did not install apps or update some existing ones before this happened. I also did not reboot. It just happened. Put it in my pocket and next time I got it out there was the red cross.
In Phone Info -> Status it says under signal strength "-111 dBm 1APU". It all looks like the antenna is broken, but I didn't hit it, drop it, put it into water or hurt it in any way before this happened or the 3-4 days before. So I'm really lost here.
Anyone? Thanks in advance.
Hi. Have the defy for about a month now. Same issue since first day. Dont know whats wrong. Found out that after 4-5 reboots its ok and lasts till next reboot/switch off. So try turn it on/off 4-5 time or just download a quick reboot app and do the same to see what happens. If aneyone has any idea on how to fix this?
i get this all the time when i flash my defy thru any other rom......and thus roll back every time to stock (indian) rom.....
try flashing your phone with any compatible rom....new radios might get ure phone working
Same problem here. First time today, spontaneous, after a month of use my Defy, non rooted, never unlocked, standard noMOTOBLUR, just like as it was bought from store. Moto_Versiuo.2.34.1.MB525.Retail.en.SEA
None of these worked to restablish the radio connection: succesive reboot, manual/automatic network search and choose, succesive airplane on/off. I didn't check the signal parameters.
I thought that the SIM just burned, removed and try it on another phone and everything was OK. When put it back in Defy, the network connection was established.
The experience was very strange and my final verdict was that the SIM just moved a little from its initial position.
BUT now I realize the problem is more complex and I don't know what caused it !
I have also noticed that the sim card slot gives a little more space for the simcard to move (at least on my defy). Might be a prob with the sim card being old or something (mine is from 2005). For now i'll just try to keep my phone on (seems i finally found stable settings for setvsel, so no more unexpected reboots).
An answer from motorola's official support forum is just remove the simcard and clean it with some cloth...
This is definitely a sim slot/card problem. If bought from amazon they will oblige to change it without any money. I did the same but not for this problem.
If you think there is some problem with software, which is unlikely then flash an sbf and see if things are fine.
To begin with flash chinese froyo sbf. It is downgradable to any previous firmware you were using and very flexible.
Hope this can solve your problem. Get back on what the result is.
Same here...
My defy got network yesterday at 07pm til mid-night.
before, since 16 (11pm) til 19 (7pm) before it function again.
and now, its bloked.
i rooted my cell one month ago, then, probably thats not the fault of z4root.
Sorry about my badass english, i still in upgrade mode.
any idea about it guys ?
thnx

Problem solved replacing sim card with a new.
Hello there, this is my first post here, I searched all the forum but could not find any solution to this.
I have a Optimus G E987. Unrooted, unflashed, with original rom, didn't do anything to the phone yet as I recently got it from a friend.
My friend was under a different carrier that I am. Since his contract had expired I was free to contact his carrier and get the unlock code to unlock my phone by IMEI. After succesfully unlocking the phone, I inserted my old sim card, it was a Standard Sim so I had to trim it to fit on the Micro Sim slot the Optimus G has.
Everything worked beautifully until I started having signal issues, both data and phone.
It does not happen everywhere, but it definetly happens at places I had perfect signal with my old device like my work place. To solve it, most times I can go to the network settings of the phone and choose the auto select option. This restores the service but I lose it again in a few minutes. Sometimes this does not fix a thing and I can not recover service at all.
I know its not a hardware issue as my friend had no signal problems whatsoever. Maybe I need to set up something in my phone to get it to work properly but I am completely clueless. I suspect it may be the sim card as well.
Any help will be greatly appreciated.
I have a T-mobile G3 (obviously) that I've had for about a year and recently it has been saying that the sim is either invalid or not installed. This is the same sim card I have been using for a while. Occasionally after several restarts and removals/re-inserts I can get it to work for a bit but then it will to back to invalid sim. Does anyone have any suggestions of what the problem might be or how to fix it? I get both the invalid sim and sim not installed messages.
Is a SIM card from a different carrier installed? Have you tried a new SIM, performed a factory reset, or possibly shimmed the card so it fits tighter in the slot?
Nope. T-mobile sim card and a T-mobile phone...all my previous phones I have rooted or at least unlocked or something. I have done absolutely nothing to modify this one from stock.

did you figured out the problem? It just started happening to me.. super annoying...
Nothing that I tried worked. Ended up deciding it was a hardware issue that wasn't worth trying to fix.... I was thinking of replacing the Sim tray but that's close to impossible on that phone. Ended up just trading it in for a G4

Old topic but the same thing started happening to me this week. At first, it wouldn't happen till I would reboot the phone and it was pop up with the no SIM card symbol and subsequent reboots wouldn't clear it.
EDIT: Tmo D851 with same Tmo SIM card since purchase, on Tmo network this whole time.
Surprisingly, flashing an old backup img would fix the issue for a day or two and upon another reboot, it would be back.
Now this morning, phone was sluggish and locking up, rebooted it and the dreaded symbol was back and no matter which backup img I used, it wouldn't clear. I had thought it was one of the app permissions I had blocked (though none were system apps) and reset all permissions, cleared all caches, thinking it was a software issue. Still wouldn't clear.
I even went so far as to do a complete factory restore via the LG flash tool, right back to out-of-the-box-new, and STILL the no SIM card error was there. Tried rooting and flashing another backup, still there. Add in numerous rinse and repeats of various steps and still there.
Went to T-Mobile and they swapped for a new SIM card and it was still popping up. They did the normal, factory restore from the settings menu, still there.
I was starting to think Tmo was blocking my account due to my data usage (paranoid, I know...) and asked if my account was being blocked or my number and was told nothing listed or said.
Of course, the 1-yr warranty on this phone just ended in September and I'm high and dry with getting this fixed.
Also of note, none of the pins are broken, misshaped, flat or other. I even tried placing a business card piece on top of the SIM card to try and see if it wasn't making contact, still no joy.
The SIM card does work in one of my old Tmo phones, so it's not the account.
Just sucks that this phone is now crippled from such a silly mechanism as such, first time with an error/problem like this with SIM card phones. And I kept this phone in pristine condition, no drops, water, glass protector, etc. And it has never been dropped or other, just started up as such... My wife has the same exact phone and no problems with her's. Yet.
schneiderm3709, did you trade it in at a Tmo store? They took it with the SIM card error or you didn't mention it? Did they take it with the SIM card error at a reduced value? If either, what did you get for it?
Thanks.
Yeah, I determined that it wasn't the sim card either. I'd have no problem putting my sim in another phone, and another sim in my phone would have the same issues.. All the flashing and everything did nothing for me. I also tried a piece of paper on top of the sim card when I slid it in to help it make better contact. This worked for a little while but eventually didn't do anything. My hypothesis is that one of the pins was going bad/had a crack, and when the sim card was installed it would lose contact, and when you took it out it would pop back up to where it's supposed to be, so you couldn't see the problem without microscopic inspection.
I told T-mobile exactly what was happening with mine, and they tried all the same things they tried with you, also still to no avail. Their requirements for trade in are very simple actually, 1: NO Water Damage, 2: NO Screen Damage (General wear scratches are okay), and 3: The device turns on. Mine did all of this, just wouldn't connect to the network. They gave me $100 credit towards the new G4. I Love it and don't know if I'd ever be able to leave LG world....Unless maybe the droid turbo somehow comes over to T-Mobile. I don't know if that trade in value has changed now since the LG V10 came out or not. Hope this helps. Let me know if you have any other questions.

I have the same problem too! Really frustrating, I've tried everything and I cannot pinpoint the problem.
I found the following solution by stevenpurwadipura on Reddit
Guys, i found a fix for this. I just figured out this trick, so i don't know if this is a real fix or just a luck. Go to settings - apps - choose option - configure apps - modify system settings - choose option - show system - select NETWORK - change it into 'No'. Then restart your phone.
I restart my phone and it detects my SIM again. But as I said, I'm not too sure if this is really a fix or just a luck.

Invalid Sim Card error in LG G3 tmobile
Hi.. I'm getting the invalid sim card error after restarting my Lg g3. The sim card works fine on my husbands phone.. so guess its same issue as yours. Did you have a valid warranty when you got the 100$ credit from Tmobile for Lg G4?

Invalid Sim
I too have the same problem for sim 2 in my LG G3 D858HK. Factory data resetting did not solved the problem. I do not know what is the reason, But now i could solve it by resetting network settings. Software version - Android 6, D858HK 30b, In back up and restore there is an option to reset network settings. Done this for sim 1 and sim 2. Problem solved.
i am having this invalid sim problem after upgrade to 30e;
I found a fix for this. i don't know if this is a real fix but just flipping from yes to no and vice versa followed by reboot seems to work consistently.
i copied it. credit should go to the original poster
Go to settings - apps - choose option - configure apps - modify system settings - choose option - show system - select NETWORK - change it into 'No' or vice versa (from no to yes). Then restart your phone.

Same thing happening to me. I took it to a t-mobile store and they said the network upgraded and some phones are now obsolete because of it. Also, because they don't have contracts anymore, I cant get any deals on a new phone even though they didn't warn me that my phone would stop working.
Hello everyone,
First of all thanks to all who had solutions. All worked temporarily. I have a stock TMO D851 30G with the stock MM 6.0 TMO ROM. It has worked awesome for the past three years I have had it. I have it unlocked via IMEI and no root....yet. I started having this issue about a 4 months ago. I sent the phone to LG and the "techs" there checked the phone and found no issues. Still having the same issue. However, I found that if I restart in safe mode it acknowledges the SIM and works fine. Use it in safe for about 30 minutes and restart. I get my network back. I am stuck. I figure there is something in the firmware or ROM that is causing a conflict. Any ideas???? I am completely fed up and out of ideas
Sent from my LGE LG-D851 using XDA Labs
Update to this problem. It is actually a hardware issue. However it does not have to do with the sim Tray at all. It is due to a bad connection on the processor. Took mine to a repair shop here in my town in mexico. He did a reball on it (flux and reheat of the processor) this was two weeks ago and it has completely fixed the issue. Hope this helps the group out. Thanking all of you that threw in your two cents. It was all helpful
Hi..
I have a Zenfone 5Z, bought on GearBest, so yesterday it updated to the latest WW version o it's on. After updating it lost the Network Signal, even after a several restarts. I've downgraded it to WW__ZS620KL_80.10.8.54_MP_user_20180517175955 , but still no network signal.
I've tested my simcard in other phones, other simcards in my phone, but still nothing. When i try manual network seach, it gives an error, and when i select automatic network, it says that is already registered to network, and when i try to make a call, it says me to turn off airplane mode to make a call. Also when i remove and reinsert the simcard it recognizes it a makeme chose betwen sim 1 and 2.
I've attached few screenshots too.
Pleaase help me guys!
P.S. i gave this phone to my wife on her birthday, now, she is mad with me!
HI,
I had this same issue, later i checked up with service center, they told charging pcb(which contains antenna lines) was water damaged.
Then got replaced the part and started working again.

Hi, Yes, even I had not let my phone get wet or dropped but phone is so worst when it comes to water resistance.
Smallest moisture in hands while using the phone is enough to spoil the PCB.

Nop, i had to send the phone to Asus authorized service center, they changed the SUB PBA...
I works for exact 30 days and, after a restart becouse the system crashed, it has no network again!
so i sent it to serce center again today...
As I don't see a reply stating how it got resolved, I will post my experience of this issue. Firstly, this issue is fairly common with Huawei 5Z. The reason given by local service team here is at times if the phone experiences some jerk the contact from antenna to motherboard breaks. At times it could still remain connected in which cases person may get signal some time and get airplane mode at others, in many cases airplane mode is ON permanently. Apparently they have some kind of a glue with which they can attach the antenna permanently. Once I got it done, the problem has not resurfaced.
P.S. this problem has got nothing to do with software, so restart, factory reset etc. will not work, nor does it happen with software upgrades. It is purely mechanical in nature and does not need even require a drop. but the solution is quite simple provided the service centre team knows. In case they don't just ask them to stick the antenna connector with a proper glue and it should be sorted.
What am I supposed to do with my set. I imported it to my country and can't find a service center anywhere in my country. Apparently I can't find any solution online so I am out of luck. If there is anyway I can fix it, or anyone could share what should be replaced will be immensely helpful.
Need your help guys.

Based upon above comment if the root cause is same as described i.e. connection b/w motherboard and antenna bands is broken then you can watch teardown video on YouTube for 5z by wit rigs. It shows how you can disassemble each part of the device for repair.
Apparently you will need to have some expertise and tools available to perform the task yourself. Better work with some local mobile repair workshop and explain them by showing video and above comment.
i am currently using 5z and i can says its due to updates especially from oreo to pie ( yes this problem is originated from that update). Its a software problem and they cannot solve the bug till now. There are still lots of 5Z with this issue pop up every week. The solution is to send to service centre to replace the motherboard and pray it wont happened again. This is my second time sending my phone there for the same issue. The antenna or motherboard dont simply fry or disconnect after an updates thats for sure.
Randomly changing different sim cards in the sim slots along with fiddling with the mobile data setting that comes when you insert the sim card tray worked for me, it worked for someone in zenfone forum also. Give a try and let everyone know..
Same here, after update signal lost... damn ASUS
My network signal stopped out of the blue and not after an update.
I tried changing sim cards in a lot of different combinations, but nothing worked, but the phone always found the sim cards.
I disassembled the phone, removed the antenna cable and attached it again and now the network signal is back again.
I had same problem. After the latest update, Everything working fine untill one day i restarted my mobile. Damn.. After reboot, the signal disappeared and can see 'x' at signal bar. I have rebooted many times but of no luck. Then i removed the sim tray , swapped the sims and then the signal starts showing. Initially after the update, one time I faced same issue but that got cleared after I disabled and enabled the sim in "Sim Card Information". The only issue i a, facing is the signal drops for every few minutes or hours and comes back automatically. That's what making me to replace my phone other than ASUS. Does anybody have a solution for this issue?
Update :
My phone had a sudden reboot and since then there is no network. Showing no service even if i swapped sims and re inserted. frustrated with ASUS

No. In my case/In most of the cases, its not the harware issue. initially i thought the same. But later found that only after updating to the latest update i faced network loss issue. sim not used to detect even after taking the sim tray out, shuffling with sims. I downgraded the firmware to previous version and then immediately i could see full network signal. So the issue is only with the latest, not with the hardware. Just give a try and confirm..
The same i have mentioned in that post also. Just give a try and update. Definitely that will work

So I can do the same as you: downgrade to get fine.
But how to still updated firmware and keep the signal?

The only solution is to walk to the nearest service center and make the antenna fixed. I have given my phone to the authorised service center and they resolved the issue by applying glue to antenna (they told same). They charged for the diagnosis as well as for glue. They guaranteed that the issue wont repeat. But i hated the service by ASUS and planning to go for samsung or Oneplus.. My suggestion is go to service center to get it fixed
For all of you still facing the issue, the solution is extremely simple. And yes it is purely mechanical in nature just like someone mentioned too. I just wrote a post regarding this. Check it out.
