Someone sent me a htc m8 from uk(not locked on a specific network) to fix it because it was broken, i did and i also unlocked bootloader and installed custom rom(leedroid). Everything is working fine, except the phone si not reading any sd or sim cards.
Before changing the sim and sd card part from the phone with a new one, is it possible to fix it without replacing it? Can the problem be because of unlocked bootloader or some firmware incompatibility ?

What exactly was "broken" and how did you fix it?

Unlocked bootloader, no that isn't the cause.
Firmware? Maybe. It seems strange that both the SIM and the SD are broken. Those slots are separate, and on opposite sides of the phone. So it would seem that a hardware problem would also seem unlikely, unless they happened to have been broken separately, and coincidentally. SIM not working due to a firmware or radio issue, is a pretty common issue. But I haven't seen SD issue related to firmware/software, that I can recall.

[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.
i having same issue in M919
Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution
Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.
Hello I have an unlocked SGH-T989D phone but the problem is it will only detect sim cards from Koodo even though it is unlocked, I've tried flashing many different roms and different radios but nothing is working. Currently on stock 4.0.4 /T 989UVLE1, yes the phone is unlocked I checked multiple times. Anyone know how to fix this?

How do you check if a phone is unlocked if any SIM you try from another company is not read by the phone?
I think you need to try the unlocking procedure again, I don't think it was properly unlocked

What method did you use to unlock it?
I did it with this (http://forum.xda-developers.com/showthread.php?t=2024514) and not a single time was I asked to check with the code that you have showed me
This IS for the T989 though, not sure if you can use it for the T989D or if it's different in a way.
Sorry that I can't help, I hope you get the answers you are looking for

My brother used that method a long time ago and he was able to use different carriers, but now nothing works but Koodo, and I never get asked for an unlock code, just says 'No SIM card'

Yeah, this phone will not ask you for an unlock code, if you follow the procedure correctly it will read any other SIM card on it's own
Try unlocking again with what you have, the stock 4.0.4 and UVLE1 combination, it should be the right one. Do the procedure again until it reads the SIM card you want.
Another possible problem could be that your SIM is damaged or not well placed. It happens to me when I try to fit a Micro SIM on it, if it is not well placed it will not detect it. Try using other SIMs or try it on other phones to see if your SIM is the problem

I tried unlocking it again, doesn't work, tried different sims, and still doesn't work, but those other sims work on different devices. Only the Koodo one works on mine, which was what it was locked to before unlocking.

Well in that case I'm all out of ideas.
One final question, when you insert a SIM on your T989D that is NOT Koodo, do you get an "Invalid SIM", "No SIM" or just an empty signal bar?

It says "No SIM card.|Emergency calls only"

My conclusion is that it's having a hard time reading the SIM card. When you put another companies SIM card in to a LOCKED phone, it will show as invalid SIM (sometimes it even shows signal but is unusable). Since it says "No SIM card", I believe it's more of a hardware problem than a software one.
All I can think of is try moving the SIM card around, turn on. If nothing changes turn it off and move a little again, the turn on and repeat until it reads it.
Apart from that, I have no clue what could be wrong with the phone.
Turn on your phone without any SIM. If you get the same message (No SIM card.|Emergency calls only|) then it is most definitely your phone not reading your SIM correctly. If you get Koodo signal WITHOUT any SIM inserted (which I doubt but it CAN happen) then that means you have a faulty SIM Card Reader on your phone.

It works on Koodo but only if the sim is inserted, also I tried moving the sim around and it still isn't reading. I think this is a software issue.

Sorry man, I'm all out of ideas. I mean I've experienced the problem with the "No Service" thing, but I basically fix it by switching to 2G since I know there are some areas that I can't get 3G coverage. As for your problem, it's basically not reading your SIM entirely (by either software or hardware issues) and I wouldn't know how to get around that.
Best of luck to you
As above really. Not really sure if it's a hardware or a software error here. I've read that the sim card readers can be a little fragile but there was no fuss during the removal so I would be surprised if that was the issue. What I'm wondering is if I've missed something when un-rooting my phone.
I was using a custom ROM, all working fine, but I've got a new phone so I decided to unroot my old one to sell on. I flashed my original firmware using the LG Flash Tool. Firmware file is "UK Vodafone 16G D85510A_00.kdz". It all went great as far as I could tell and I started upgrading. The final upgrade was the install of Marshmallow 6.0.
In order to find out if my phone was locked or not I put my Wife's SIM in. Rather than coming up and asking for an unlock code it simply stated that there was no SIM inserted. I thought that was potentially down to the wrong SIM being in but when I tried mine I was met with the same error.
Have I missed something? Did I need to change the baseband or something during the process?
Any help would be greatly appreciated.
Thanks
I've had kinda same problem since a couple of weeks ago...eventually SIM card gets read for a short while and get back to that No SIM card inserted state.
It has happened with any ROM as well as OG FW flashed through LG tool.
I haven't tried another SIM on my G3 but my SIM does work on other cell phones.
Hello.
one part of the problem is mentioned in the title. here I will elaborate. my guess is that the SIM slot has it's contacts dirty or bent.
now,please bear with me,this is my first post on XDA. I tried pretty much everything,and I've turned to this wonderful community .
anyways,my IMEI is still intact, and the only big problem about this phone is the SIM. I'll gladly wait for your help. My SIM card is intact, and I've changed ROMS. Currently running Eclipse V9.
.
Does this happen with the stock rom? Is the phone running the latest bootloader and modem?

Yes,it happens with pretty much any ROM . And I've forgot to mention, sometimes I'll make the SIM work ,only by twisting and putting it back on.

Phone detects other sim cards?
Your sim card works in other phones? If yes, then you might want to try changing the sim reader.

No, the phone doesn't detect any SIM card.
My SIM Card works in any other phone.
Sounds like a defective sim reader that needs replacement.
I used to have a problem close to that. While using the phone I suddenly got a " no sim card" message and needed to restart. I placed some tape on the back of my sim card so that the tape will press the sim card towards the contacts and it helped me. You might try it.
Hello friends.
I am encountering a very strange issue with my A70 (FN model). I have a SIM card dedicated for internet and I was using it without any problem on my A70. Then one day I was trying to root my phone while SIM cards (I have 2 different provider's SIM cards) were inside the SIM tray. I had to reboot the phone multiple times during the process. Later on, when I finally set up my phone I noticed there were 2 circles in place of network signals signs. And an error MM2: SIM CARD 1 IS NOT ALLOWED. SIM card 1 is the one I use for internet. I swapped both the SIM cards places inside the tray but the same error kept on popping up. Eventually both SIMs were not being detected.
I tried many cures for the problem, went through a number of possible solutions by watching videos but....NOTHING!
Next day I got new SIM cards with the same numbers as I thought that maybe my SIM cards were damaged while I was rooting my phone.
Now the SURPRISING thing is that the other SIM card started working but my internet SIM card still didn't work. I put that in my LG G4. It worked there flawlessly. Further, I tried few other SIM cards of my family from the same provider....NONE OF THEM WORKED!!!!
Now my question is IS IT POSSIBLE THAT ONLY A CERTAIN COMPANY'S SIM CARD DOESNT WORK/STOPS WORKING ON A PHONE WHILE OTHERS HAVE NO ISSUES ???? is there any way that the SIM provider has blocked my phone?
Can anyone plz help?

You are absolutely right. As far as I remember I did click on Nand Erase as I was unable to flash the Patched AP by normal settlings of Odin. (Although it still didn't work. I had to flash fulll Stock ROM). Can the damage be reversed?
By the way, I did flash later on full latest stock ROM of the same CSC (SEK) but still the problem persists.
