[Q] Sim no longer available 4.4.2 stock samsung rom - Galaxy S 4 Q&A, Help & Troubleshooting

Hi I have been using the stock samsung rom of 4.4.2 installed OTA. It worked fine for several months and just recently the simcard is no longer visible which also means the IMEI number is also gone.
I have replaced the sim reader after trying a reflash of the samsung firmware to the same version.
I then tried rooting and using a custom ROM with some success for a few minutes but there were other issues so have used Odin to go back to the original firmware, hoping for a miracle, to get mobile network access.
Is this a common issue?
Is there a working fix?
Have I done something wrong or do I need to do something else?
Thanks in advance, my phone is a GT-i9505 4G

Looks like a hardware issue. Get it to repair to one service center.

I've been having the same issue with mine, although mine came about from being dropped too many times. My SIM stopped being read, then when I replaced the SIM/SD flex, both cards stopped being read.
Took it into a phone shop to have the flex replaced again (assuming that the one I installed was faulty) only to be handed the phone back and told that the motherboard is stuffed. Since mine's been damaged as much as it has been, it certainly won't be covered under warranty, so that's not an option for me. I'm basically up for a new phone.
Good luck

Help: No service.

I have a tmobile wing and I had it for awhile but just started using it again recently but when i put my sim card in the phone and turn it on it just keeps saying Searching...
I get service for like 2 minutes then it would just go away. This would happen when I leave the sim in the phone, it would get service once in awhile, like for 2mins every 2-3 hours, but never consistently.
My sim card works perfectly on other phones and when i insert a friends sim card into the wing it still has the same problem, it keeps saying Searching... I don't think its a problem with the sim card since it works fine with other phones.
I tried soft reseting it and hard reseting it but it still seemed to have the same problem. Does anyone have any idea what the problem could be or what I can do to try and fix it?
what radio rom does your phone have and what rom are you using?
you can check your radio rom by going to settings>system>about ( i believe). If not that, then settings>system> device info.
also, if you don't know what rom you're using, it's probably the stock rom.
It might also be that the particular spot you are in is just unlucky for reception and that other phones have better reception by design.

It says Radio version: 02.83.90
And i believe it is the stock rom since i never changed it or anything. and I doubt it is the area because I tried using it in several other towns.
anyone have any idea what could be wrong?
p4350
well on my p4350 over the past 2 weeks i have been receiving little signal like every 5 - 7 hours i mite get it for a bit but only for a sort time. i was wondering if it needs its radio updating?
any help?
Hi, I just want to share my story. maybe it could help you out.I had a wing for more than a year now. recently it had the same problem. it just don't have any signal at all, just keep searching. I tried what you did before. hardreset, softreset, and update the firmware. Nothing helps. since my phone is out of warranty, i can't send it to t-mobile. So i went to a local repair shop. They told me it could be hardware problem. I paid $50 to get it repair and no problem since. I don't know what they did, maybe replacing something inside. So don't just look at the software side, it could be hardware problem.
I have the exact same problem, and it's really pissing me off.

[Solved] HTC HD2 Touchscreen not working, not responding, frozen, malfunctioning

The Problem: My HTC HD2 touchscreen has progressively gotten worst over 2 months. At first, the keyboard was typing up wrong alphabets, then major function keys begun to malfunction, and later the whole screen. From XDA reviews, I found that changing Radio, WM, or Android ROM do not help.
Solution:
This instruction may apply to Tmobile USA users. In my search for a Do-It-Yourself fix, I searched internet for several days to no avail. Amazon.com sells Touchscreen and Digitizer but their results were inconsistent; the replacement also required time, skills & instruments that I do not have.
Tmobile: Tmobile (800 number) asked me to restore OS, but it did not work. They asked me to take it in the Tmobile store. The store associate looked at the phone, but they did not want to do anything with the phone as I did not buy my phone from Tmobile - they directed me to HTC or a local repair shop. Local repair shop was going to charge $100 for a repair and turn around time of 15 days.
HTC : I called HTC (888 356 2375). As the phone was still under warranty, they offered to take a look at it & repair it. HTC also mentioned that if the warranty is void for any reason, they would charge $39.00 for a triage fee and call me to confirm the repairing cost (in addition to triage fee). HTC mentioned that any illegal softwares found on the device would void the warranty.
Restore to OEM:
I had to restore my softwares to OEM as I installed a newer radio, HSPL, MAGLDR, and a custom windows ROM. To do so, following ROM was flashed :
RUU_Leo_1_5_TMOUS_2.10.531.0_Radio_Signed_15.34.50 .07U_2.08.50.08_2_Ship
Flashing above ROM restored ORIGINAL OEM radio, SPL, and Windows ROM. It also removed MAGLDR.
After restoring softwares to OEM, I sent the phone in. The repair was done by HTC without any charge. After sending the phone in, I had my phone back in 1 week - fairly quick service compared to all the other options I had at hand.
In the process, HTC kept me informed via email regularly. I talked to several HTC reps and they were very accommodating and courteous. I mentioned to HTC that my battery drains very easily. Promptly (in 2 days), HTC sent me a replacement battery for free. They mentioned that as long as the phone is under warranty, they will replace accessories ONCE for free. I will buy HTC again despite the touchscreen problem.
Immediately after receiving the phone, I installed newest Radio, HSPL, MAGDLR & my first Android NAND [HD2_Core_Droid_Desire_HD_V1.4_NAND_ONLY_LEO1024_TOUS]. The android ROM is rocking even harder straight out of box.
Enjoy.
Had the same, perfect service from HTC.
Got it back in a box that said "im back" .. Took 4 weeks though.
This made my decision to stay with HTC in the future.
Same problem, possible not yet solved
My UK T-Mobile HD2 started this in December 2010, I found that 3 or 4 hard resets got it going, but the next day it did it again so sent to T-Mobile repair center, they stripped it put it back together. No Fault Found. Updated the firmware (well re-installed it as there was no newer version avaialble at the time and sent it back to me.
It worked a treat for 5 weeks then the problem was back. Sent away again, Firmware update. No Fault Found (T-Mobile had now released the 3.14 ROM) so I did get an update this time, again came back working. Even better this time as the new radio version allowed me to run an SD Android Build.
You know where this is going, lasted 3 or 4 weeks, same again, Back to T-Mobile Store, this time I did not try a hard reset prior to taking it in, so they could see the fault, I did one reset in store and the fault persisted as it always did after the first two or three, and then off to the repair centre again.
Its due back in the next day or two, No Fault Found!!! Firmware updated
I guess it will be going back again a 3 to 5 weeks.
Perhaps I should drop an e-mail to HTC to see if they can help.
Do you know what they did to yours, did they replace anything?
Cheers Bashy...
My display was soo broken that an firmware upgrade didnt help, not even for a second.
On the repair note (0eu) it said that my screen was replaced.
I had the same problems as in the OP.
Running beter then ever now.

No doubt, Tmobile attempts to be helpful. But, I consider HTC, as a manufacturer, to be well-prepared to deal with their own product's issues. If you have these problems repeatedly, I recommend you contact HTC directly. They may send you a new replacement instrument altogether. I had several positive surprises from HTC.
HTC No Longer Repairs HD2
I know this is an old thread, but I have an HD2 with a digitizer that quit working that I wanted fixed. I just called HTC and was told that they have not been able to find a proper way to fix the phone and that they would not be able to repair it even if I paid them. This came from the customer service manager. Both the service rep and I were left without words. He couldn't believe that this was the response as he has never heard of such a thing. HTC has taken the HD2 out of their repair database. Seems pretty sketchy to me. Obviously they know about the problem and it sounds like they should issue a recall on the product if it consistently breaks on people with normal use and they have no way of repairing it.
HD2 screen not working
They fixed mine on Feb 22, 2011 for free under a warranty. I suggest you do not give them the diagnosis of digitizer is not working. Instead, just tell them the problems you have and let them tell you what is wrong with the phone.
If is going to cost an arm and a leg to fix the phone or a 1 month of outage from cellphone, I recommend you get a new phone from Craigslist or eBay. HD2 are dirt cheap now. Good luck.

Yep - i'm not surprised. I purposely bought the HD2 to get dual boot setup. Lasted two months and then screen stopped responding when screen locked. Eventually could not unlock at all. I stripped the phone, put in new screen and digitiser and new keypad buttons and then flashed back to original rom too.
GUESS WHAT??? STILL BUSTED.
So you can try many fixes found online, but I reckon once it busted don't waste your money just bin it.

From what i've seen too, it is very difficult to actually repair the digitizer without causing new secondary problems. I paid my repair shop over 155 usd to repair an hd2 with usb and touchscreen problems and they just replaced the virtually the entire hd2 (mainboard+LCD+digitizer). And it still had problems in the end!

hey dood, i had nand on my US tmoble HD2 touch screen went out, i have a few posts you should follow if you are going for warranty.
i had to download the software from the tmoble website..... You will need an IMEL number for this ...... or go and try to find your stock rom on the interwebs...... have a secondary SD card (not the one in your phone) follow the SPECIFIC steps and drop your new file on the new sd card and replace it with the one in your phone then follw normal booting steps in the tri color screen.,..... i do have a post that is a quck rundown with a little bit more info........ but the main thing is.... if you send it for warranty you have to put YOUR (country/carrier specific) stock rom on or they will fully charge you....... hope this helps....... other than that its a phone issue i belive its the screen digitizers.... so if not under warranty thats what it will cost to fix
Thank you
Thank you. that helped me as well.

Nexus 4 - No Service

Hi all,
I got a Nexus 4 from Ebay. Cellphone is in flawless condition, it probably has less than a couple of months of use. Unfortunately, I am not able to pick up a signal in any way. I just get a constant "No Service" message, and occasionally it will jump to "Emergency Calls Only".
Testing menu says Signal Strenght is 0 dBm 99 asu, no neighboring cells and location is unknown.
I've tried changing the prefered network to WCDMA only (as suggested in other threads), also tried with the other available settings with no luck. Tried playing around with the Change Bands setting as well but it makes no difference
Tried with a few different sim cards as well but that didn't work either, just got signal momentarily and but it would go on and off.
Cellphone came with 4.2.2 and I upgraded to 4.3 as requested by the system. Same issue.
Tried basebands 48 and 84.
Tried CM 10.2.
Replaced SIM card with a brand new one.
Cellphone doesn't appear to be blacklisted either.
Not sure what to do next. I'll try to get in contact with the seller but I don't expect much from him or eBay. Maybe I can sell off the device very cheap for spare parts, or send it for repair somewhere? Leave it as a dev device (which would virtually indistinguishable from a N5 that I plan to get anyway), Anyone else has any other suggestions or ideas?
Try to install a factory stock image: http://forum.xda-developers.com/showthread.php?t=2010312
If you pay with PayPal you get buyer protection so you can try to get your money back.
Could be a hardware or antenna issue.
To me it seems like its been blocked for certain reasons. Either it was reported stolen or the person who sold it to you didn't pay his/her bill for which the carrier blocked it. In that case you can't do much about it.
I would contact the seller right away. If you get no response contact paypal and eBay.

This problem is occurring for a lot of Nexus 4 users, including me. Its some sort of pandemic. Here’s what you can do to atleast restore service to your phone : flash the factory 4.3 image to your phone, again. However, try flashing a radio that is 54 or older with it. Make sure you wipe the cache and flash all the partitions, system, boot, bootloader and the old radio. This will bring back service to your phone (did for me), however you will be left with no in call audio and your phone wont connect to the internet through the mobile network, only wifi. After doing this, you will see your baseband and IMEI in the phone.
You can use this as some sort of “test” to verify if your phone really isn’t stolen. What is the ultimate resolution to this problem ? I really don’t know yet. I’ve been breaking my head over this for the past 4 days now. Maybe I’m going to try out the unbrick method mentioned over here to see if that helps.
As an update I am getting intermittent signal in some areas, but it's really spotty and only lasts a little while : (
I'll be giving different basebands a try tomorrow but I don't think it'll help much. I'll also try the full factory flash posted above.
Same problem here, had the phone for about 2-3 months, bought it off Kijiji, I tried flashing 4.2.2, went back to 4.3, flashed every baseband and still no success. The SIM works perfectly in another N4, tried a few other sim in mine and still the same results. Any other ways somebody got this fixed ?

I'm talking to the seller, see if the phone is still under warranty. My other options would be to change the antenna myself (see if it works), or resell it at loss for spare parts, or wait to see what eBay says.
Just to give you guys some hope, that this is not just a problem faced by second hand phones - My phone is bought directly from the Play store - I contacted Google service a few days back and they asked me to return the phone for a replacement. Only problem is I have to ship this back to the US (where I purchased from), since they dont provide replacement service outside the country of purchase. I'm in India now.
I've tried absolutely everything myself. Flashed many many radios, 4.3, 4.2.2, I'm only able to get it to the point where there is network coverage, I can make and receive calls but there is no in call audio, nor is there any mobile internet connectivity (Only through wifi).
Something tells me this is a problem with the latest OTA update that caused this issue - I was completely stock and everything was working properly, when this problem appeared one fine day - It started with me not able to connect to the mobile internet network for a few days, and then one fine morning, BAM. No service. It was only after this that I started flashing and re-installing stuff on my phone, desperately trying everything to get the phone back to normal again.
I think the last OTA update somehow "bricked" the radio (dont know if something like this is possible, just a noob guess). My only hope is the 4.4 update has some fix for this, else I'm going to try the unbrick method mentioned on these forums to see if that works. Only then will I take the pain to send this back to the US.
What's the unbrick method you are planning to follow?
I was considering using the unbrick method listed here : http://forum.xda-developers.com/showthread.php?t=2347060
Although I'm not completely sure it will work. Do you or anyone else have any suggestions for this ? I'm hoping 4.4 gets released ASAP, I'll download and root that as quickly as I can, hopefully Google has some resolution to this stupid problem
i have exactly the same problem
i have exactly the same problem. i bought my phone at US from Google play.
the phone worked fine for two month and then i got - No Service, and its swipe in a sec to emergency call only.
i try to replaced some sim cards, and factory reset with no success.
i also read a bug report that opened in Google : 58317
they told that there is a problem with the radio interface and radio driver at the 4.3 update, and they will fix it in 4.4 kitkat version.
i hope that 4.4 will fix this terrible problem, if not the phone is totally a door blocker..
Did anyone ever find a solution for this issue?
My friend has this problem with his Nexus 4.
I've searched A LOT and to this day (half a year later) haven't been able to find someone who reports this problem was solved.
I've also tried every suggestion I could find: flashed every stock image available, tried every combination of stock/custom ROM/recovery/radio, even tried the unbrick method mentioned above.
Nothing helps. I always get the same symptoms:
- Radios 54 and below - no in call audio.
- Radios 83 and above - Baseband unknown, IMEI / IMEI SV unknown, no cellular reception.
Also, RMA is not an option because the people at the store (a) don't know how to fix it and (b) claim the warranty doesn't cover this issue so they won't replace the device.
Any suggestions? I'm willing to try anything...
Maybe its a simple hardware failure like a loosely connected antenna? It doesn't really seem to be connected to any specific software setup
Something that happens to me rarely: when I'm in an area with very low/no reception sometimes the phone won't reconnect itself again and just stay on no reception until I reboot. Only happens like one or two times a month though.

Thanks, but I really don't think it could be an antenna issue.
I can see how a malfunctioning antenna could cause cellular reception problems, but it shouldn't affect IMEI or Baseband version readings. Those things have nothing to do with the antenna.
Also, the fact that the symptoms change with different radio firmwares says there's a big chance this is a software issue after all.
I just can't figure out what the cause is and how to eliminate it.
Flash any full factory image. If the problem persists after you can be pretty sure it's hardware. No signal for most of the time and occasionally picking it up could be something as simple as the antenna being unplugged, which can sometimes happen after a drop, or a forgetful repair.

Could be a broken or badly connected antenna. They are very fragile. Have a look at how to replace the antenna maybe?

I have the same problem no connection but the phone recognize the sim and the number of the phone. I've tryed to return to stock using a factory firmware but I'm not able to fix the problem... (this morning is working fine and my phone never fell down or something like that)
If I open btw the case and try to remove and reinsert correctly the antenna the phone will recognize the signal?

I'm in the U.K. and have the sim error problem. Phone has never been rooted always on stock.
1st occurrence within 3 months ownership but it got to a point, after a week, where it always read no sim even after restart. Samsung warranty repair changed mother/main board.
Phone was dropping calls after the warranty repair so went back to Samsung. Warranty repair 2. Changed 2 wires, don't know which ones. But now phone was working fine.
3 Weeks after repair 2, the screen went black. I could still hear all tones etc but no screen so can't answer calls (most basic function of phone). Samsung put new screen and another new main/motherboard. So now this is the 3rd mainboard. Phone came back on 2/10/14 after the repair. After 2 days I have again got message about 5 times at a time but restart is solving it for now.
So I think the problem lies in the faulty mainboards Samsung are manufacturing. Why? Because my 1st board failed and eventually always had the message no sim inserted. The engineer report said main board was changed. If it was too do with a faulty sim tray then wouldn't they have fitted one of those instead. 2nd board worked fine even though calls were dropping. This board was in phone for 3 weeks until screen got changed so I'm presuming had to change board along with screen. The latest main board which is apparently new has lasted 2 days. Like I said above its only happened a few times so far but I rather it happen all the time so I can send it in again.
I have spoke to Samsung UK escalation and they said if I require another repair then they will take it higher up but even with an exchange what is there not to say new/refurbished S4 wont be faulty down the line.
What is Samsung doing about this, absolutely nothing. My worst ever experience with a phone and I got a s 1,2,3 which all still work not even a glitch. Will buy another phone but keep fighting for a resolution with this one. Still has 17 months warranty.

[Q] note 3 won't detect SIM card, also won't shut down

I got this from a customer he bought a new phone and told me if i could fix this then i could keep it... Decided to start here... Everything seems to be pointing to a bad update... Tried to do self recovery but i feel it needs to be totaly reflashed... I had anothet note 3 and switched the bords to make sure that it wasnt an anntenna problem or anything else besides the motherbord or software... Is there a way to fully flash this again? Like the basband and Android? I know u all flash ROMs but id like to get stock working first... Tried Kies but wont reflash it... Maybe a way to get it into emergency recovery mode so it will reflash it?
I havent done any flashing since my SII i know Odin was relivent, where would i get 100 stock verizon 4.2? And its like the old ways right?
I figured out how to reflash it.. But im leaving it's off just in case someone else came across the same problem it's almost like there's no SIM card inserted even if you pull the SIM card out sometimes it does sometimes it does it never shows the network and it never shows a signal strength over .99 also its not showing IMEI number was just super weird, it keeps pointing to bad software... If reflashing it dont fiz it ill post some screenshots...
My first note 3 killed 3 sim cards before verizon finally replaced the phone under warranty. The phone may still be under manufactures warranty if the phone is under 1 year old. I cant wait for my upgrade so i can get a non samsung device. I love the size and most of the hardware but first and foremost it is supposed to work as a phone which is does not. Plus bloatwiz is a freaking joke even in rooted custom form.
