hey guys,
I have just gotten my phone back from repair. It was getting the cracked lCD replaced.
So i went and put my SIM card into the SIM slot then i rebooted my phone, just to see a "No SIM" message which then proceeded to say "Insert SIM card". My wifi and everything is working and i can make emergency calls. I have previously had problems with my EFS folder and a corrupt IMEI but i fixed that issue and i don't believe that these two incidents are related whatsoever.
This is the thread with all of the information of my last problem. http://forum.xda-developers.com/galaxy-s5/help/service-t2898890
To try and solve this new problem, i have done the following:
1. Taken the sim card out and restarted phone and entered the sim card back in numerous times in various different sequences.
2. Done a full factory reset, reflashed a new rom, modem and bootloader.
3. Restored the EFS folder.
4. Tried a different SIM card.
This could be a hardware issue, but i feel as though it is software related, but i am no genius so i am open to any suggestions as to what it may be and how i may be able to fix it. If i am not able to fix it i will just send it back to the phone repairers and see what they can do to resolve the problem, but that would be the last thing i want to do.
thanks for any help.
not to worry. I have now solved the problem and everything is working perfectly.

i was on android 4.4.2 thouchwiz, i then upgraded to android 5, which also meant i had to upgrade the modem, which seemed to fix the problem. I then downgraded back down to android 4.4.2 touchwiz and that solved the problem.
so maybe you could try upgrading your modem or something? let me know if that works.

By modem do you mean radio?
It's an unrooted phone in my case, unfortunately.
the modem is a file or software i guess you could say in which controls the the signal on your phone.
hmmmm, im not sure what you could do then... im guessing you do not plan on rooting either?
My samsung galaxy s5 g900t started having problem this morning. I;ve been using blisspop rom since 3 month ago and everything was fine. But now my phone wont even find a signal. The signal bar is empty. I though it might have been because of an app. therefore i deleted any unusual app, and nothing happened. Then i proceeded to factory reset and nothing happened, then i decided to change the rom, and nothing happened ( i changed to 6 different roms, all between LP and MM. I proceeded to flash the stock firmware via odin, it successfully flashed the stock firmware, However nothing happened. It has an empty signal bar with and x on the inside. So far I've tried with different sim cards and it happens the same. NOTHING. My phone has been using heavy duty covers since day 1. The last cover i bought was the Love Mei one. Which is Extremely heavy duty. (combination between aluminum and rubber).However im starting to think that i will have to buy a new part of the phone. I know about phones, and software related, however i dont know as much as a professional or amateur would about hardware (external)
Can someone please give me suggestions about what to do before proceeding to buy a new part? If i have to buy a new part, which one do i have to buy? the antenna? or what? I've posted the picture of the screenshot ( look at the signal bar) Forgive me if someone has posted the same issue, however the suggestions xda was telling me are far from being the same than my problem.
Do you still have an IMEI if you type *#06# ?
If not, I hope you backed up your EFS partition before flashing ROMs

No. I didnt. Okay i though it was a lost cause. Here is what happened, somehow my EFS folder got erased, and my imei and S/N were gone along with it. After you lost those 2 essential things every company turns their back on you. So, it is either you fix it by buying one of those boxes that fix imeis and networks related, or buy a new logical board on ebay; or just give up and proceed to buy a new phone. However, even though i saw that my imei was null, and my S/N was also gone, Having no backups of EFS, I was at the edge of giving up. Until i decided to do the following: I installed the firmware that came with the phone. which it was a 4.4.2 version. Then i upgraded it to 5.0. And..... Everything was back... however my IMEI is not the same that came with the phone. Which is kind of odd. How did i get a new IMEI by just goning back and for between upgrades? Who knows.... Anyway, now I have full bar as its supposed to be. And currently 4g. (There was another thing i did but i will refrain from telling, since it isnt that interesting)
Very strange, but good news it's working
I'd would strongly advise you to back up that EFS partition asap now just in case

Ueah. I never thought that would happen to me. Thats why i never did the backup. I did it as soon as i saw that i got signal, service, imei and sn back. Haha
No-one ever thinks it will happen to them, that's why I backed mine up before I even decided to flash anything custom at all
Is there any p8 lite users or just me have problem.. cant connect to wifi even my password is correct
"Denied access to network. Connection Failed"
help me or if there's anyone have same problem let's find solution bout this
thanks in advance :crying::crying::crying::crying:
up for this , thanks in advance for helping me dev's and modders
Same issue....need help
Sadly a common problem. Have read a lot of tips on how to fix, but none have worked for me (clear cache, factory reset...).
Will probably return the phone soon as it doesn't seems like WiFi will ever work properly.
Update:
Talked to Huawei Customer Support (in Sweden) and they suggested a factory reset and trying to connect to a different AP (to verify that there was no problem with the AP). Which I have already done, so next step was to return the phone. So I just did that and they (the store I bought in in) are going to send me a new one, that hopefully works. Fingers crossed.

For me there was a problem straight out of the box. So I tried updating, hoping it would be fixed but the problem persisted.
Saw no difference in before or after update.
thankyou for your response guys ... i'll try to reflash my firmware and back to stock i'll update you guys if i have a same problem after flashing
- done flashing .. same problem still cant connect to wifi !!
someone said that the problem is the wifi chip ,, much better if i go to service center since no solution =.=
Anyone any solution to this, i can get wifi sometimes when flashing some modems, but never manage to get service.

I am assuming your IMEI is 0 now and no amount of reflashing, factory resetting helps? If so, there is no permanent solution short of having Moto fix it, although you could try this software fix for the Moto G 2015 (but change the necessary pieces for the Moto X P/S) described here.
Hello all,
Ok let me tell you what happened first.
In March I bought said phone on ebay from a guy which seemed a legit person, 150 or so reviews, a lot of stuff sold, positive reviews etc.
For the past 6 month everything worked fine and i used the phone in the UK on EE (phone is locked to EE) without problems.
on Saturday the phone suddenly has been not geting any signal so I did some invetigations and it turns out the guy who sold the phone is on contract with EE with the phone and did an insurance claim as lost or stolen.
So now the phone has been Blacklisted and i cant use it anymore, to make calls etc on any network.
I tried to get Info from |EE, Ebay etc but with no luck.
I did some research and found that i can change the IMEI number to make the phone work again.
So I must say first up that I dont have a clue from rooting or any modyfing stuff with phones apart from the normal ANdroid things.
So I did some research and after misserably failing to root the phone myself, I got a company "one click root" to succesfully got my phone rooted.
Now I tried the options to change the IMEI number but none of them works:
"ok i cant post outside links:
the 2 versions to change IMEI which i found and tried are : with xposed and imeichanger app, and also one where you have to dial a number which opens radio frequenzy and then another number where you can change IMEI number
this does not work because the xposed framework is not compatible with this phone (yet)
this does not work as i dont have signal and the "call" does not go through.
thats the only thing I found and i thought as a last resort I try my luck here if anyone knows of a different way tho change the IMEI number for this phone apart from the 2 options above before i go and spend another 350£ for a new phone (this time from a shop )
thanks in advance

I take it this means you didn't create that all important backup before modding your device? :silly:
Try downgrading the firmware first then flash the latest updated firmware

Hi guys,
I have an issue with My SM-A520F. I bought it to a particular and according to the initial network provider, this person stop to pay his subscription.
So, I'm looking for solution to change IMEI for this model. I think the nv_data.bin is encrypted. Perhaps if I change the nv_data.bin(whith the corresponding nv_data.bin.md5) with another which not blocked in my country it will work. So, if someone want to exchange his nv_data.

Hi Xposed and IMEI changer will not help you. If you want I can explain you how to install it on this phone. But the IMEI changed by IMEI changer with xposed framwork is not the IMEI sent to the network provider. The IMEI changed by this app is used to mask your IMEI to the apps that track you by using the IMEI. So it's just a spoof of the IMEI for apps using IMEI and not a really IMEI change.

Backup the EFS with TWRP then delete the EFS folder. The EFS should rebuild and give a default IMEI when the devices reboots or try deleting NV_DATA.bin, NV_DATA.bin.md5, it should get replaced by NV_DATA.BAK.bin if it's any good.
You can also attempt to Format and remount the EFS partition. It works for some devices.

Guess not in that situation, but you may be able to delete the EFS and enable the default Imei.
