[Q] N7100 Emergency Calls Only

Okay my phone has been working fine till now.
My IMEI is intact still displays *#06# the correct no. It has been unlocked. I have rooted installed a custom ROM all was working okay till yesterday. When I turn the phone on emergency calls only is displayed. When I try to make a call it pops up with not registered on network. My data works okay though so I know am not blacklisted. Has anybody got a fix. Been searching but can seem to find a solution. Please help.

you have a backup of your efs folder?

Try a data clear.
Make sure you already have a backup of efs.

Gonna have to bump this, since I have the same issue.
Phone was working fine until I tried this rom. Now every rom I try, including flashing stock using odin, leaves the phone as "emergency calls only". I've tried different modems etc, nothing.
Current baseband N71000NEDLK1.
Even flashing the proper UK 3 network stock rom, nothing.

Have you tried with another sim card? Maybe you have a damage sim.

Ive tried my mrs' o2 card, same issue there.
It feels like a rom has changed everything, my modem even. I've tried to flash one recommended for Three UK, but it didn't seem to stick in recovery.

I fear for the worst. I've read a few entries from people saying when this happened to them (some never rooted or on any custom rom) they had a paperweight.
I've tried about 6 different stock roms, many custom. Many modems. Nothing will get it working.
The phone has full signal, can scan for networks, but will not allow calls or connect to data.
I've tried the sim elsewhere and it's fine.
Since this is my only means of communication, I'm extra worried.
Any help on this matter, is greatly appreciated!

Sorry, I never had a box. My dad has been using it great for 6 months, I have it a day, stick a rom on it and boom. But I'm smelling something with the kernel. I changed the kernel and now there is no signal at all. I need to find the right one for this UK model.

I've got the same exact problem as well, my N7100 bought it from china ( not copy) and after install Hong Kong version of stock rom via Odin,I have the same exact problem.
1. I can search for all the available network.
2. Under settings-about-status, it shows my phone number, my carrier, HSDPA mode...all looks normal except "emergency call"
3. I tried calling the sim that was in the N7100 and text message, the line works,text message shows as delivered, but nothing turns up on the N7100.
I've tried custom,stock,per-rooted from many versions of the world but the problem is still there.

Correct. The IMEI is totally different. But as I said, I am not going to fix it. I'll just sell it on cheap for someone else to. It's a shame and annoying that something like this can go wrong and potentially brick a phone. I know theres risks to all rooting/custom roms, which I accept, but it still doesn't stop it stinging when it does go wrong, which to my knowledge, wasn't my fault.

First thing before you try anything else make a backup of EFS folder search for the thread you will find specific to Note 2.
then try to make a ROM backup
then Flash the stock Firmware see if this works.

Don't be paniced mate. The problem is easy to solve. With a root explorer find the folder efs_Backup, location of the folder varies from rom to rom. If you are in a custom stock rom, you'll find it under sd card. It also may locate on root/media. Every time you flash a new rom the efs backed up automatically in zip. After finding the folder, open it, you'll find many zip files mentioned dates. Extract the one you remember when your phone was fine. Then copy the whole content of the extracted folder and paste to the root/efs.
Before pasting, erase the existing contents of the efs folder.
DONE!

If the MD5 of the downloaded file matches the MD5 given in the thread, then you do not have a T999, and you bricked your phone. I would guess that you have the intl version. If that's the case, you are in the incorrect forum.

What can i do ?

That file is designed to not flash unless the checksums match the ones stored in the update script. I'm a little hesitant to link this thread without knowing what went wrong, but here: http://forum.xda-developers.com/showthread.php?t=2439367.

Everything you have said so far leads me to believe you don't have a T999, but an I930x. In which case, you are in the wrong forum.

on the back its written sgh-t999
when it was on on about section it's model was sgh-i747. phone had no imie, no baseband so i went through this process

I agree with aerowinder, your posts all suggest it's not a T999, as that's what happens when you flash that firmware to a different model. Are you absolutely certain it does not say SGH-T999L?
If it says it's a T999, then your only chance is the thread he linked to a few posts back.
Our bootloader has never been locked btw....

I had an issue with flashing back to stock after cm10.1 as well. Kept saying error but don't remember what it was specifically. But I finally got the backup to work after data format. Of course my backup was on sd card. Hope this hepl.

Try this video first listen carefully, http://www.youtube.com/watch?v=dU5H8NJ7vTM... do not download his debricked img file. Download one from this page http://forum.xda-developers.com/showthread.php?t=2345860. Your phones hardware may be a i747. I had the same problem , behind my battery says it's a I9300 and when I rooted for I9300 didn't work after 2 tries. Then I noticed when I plugged my phone in the usb it was looking for T999 drivers. So I just assumed it was t999 ... well, I ended up bricking the phone and I found that youtube video and presto, fixed. I use the img file for T999. If you think you have an I747 here is the download link http://d-h.st/iEy...do at you own risk. I don't think it matters anyway if your phone is already bricked. I just sayin it worked for me, it may also work for you. Good luck!

AOSP on Sprint $$$

$20 to the dev who gets AOSP to work on Sprint's latest 1.80.651.30, WITHOUT using foreign firmware.
We're about a year into this device, and apparently we have no developers on the Sprint side working on this.
Not sure if that price is worth it to anyone, but I'm a man of my word.

You contacted me multiple times about editing the Verizon guide for Sprint.. I took my free time to respond.. and now you post this.. A bit of a slap in the face, no? :silly:
I would contact the Devs working on AOSP personally, however with N already here (and coming soon to the rest of the carriers), I personally don't see anyone taking their time on MM (just an opinion).
I do hope you get it working. :good:

I have your zip, but haven't flashed it, because I'm not sure if it needs "modified" for Sprint.

I responded last night, and I quoted you so you'd get a notification to see it.
http://forum.xda-developers.com/showpost.php?p=70256059&postcount=15
The whole point of this method is to get back to stock Verizon/Sprint.
If you do my method you will be back on 100% Sprint (Since you are flashing the Sprint RUU AFTER the modified firmware) AND AOSP ROMs working. I don't know why, but it works. It's been confirmed on a number of Verizon users AND Sprint.
"Plus, I am looking for it to work with Sprint firmware first"
Then why did you contact me multiple times? I am not going to apologize for taking longer than you'd like to respond.. I wrote the guide for Verizon, so excuse me for not wanting to brick your device with rushed info..
Like I said, I hope you get it working.. I did respond in the thread, and as I said if you need help editing the android.info.txt, let me know. :good:

I didn't get it. Responded to the linked thread /post.
Thank you.
I understood your instructions for the firmware and RUU, but didn't think your zip would work with my Sprint device. Thank you so much for the deeper explanation.

AOSP/CM ROMs are a great way to change up the device so I understand the want to use them, hence how this method was found.

Just to make sure (on both threads, sorry), my CID is 11111111.
I don't use the Sprint CID, I change the android text to the Super CID number, right?

Okay.
Everything done and I didn't brick.
New problem.
I only have 3G, even after the RUU.
Something tells me I shouldn't have GSM options?

I can flash CM, but I can't use it.
I cannot make calls or message anyone.
If I restore my Sense backup, then I have no data. I have to erase modems again, just to get messaging back and to get my Sprint ID to return and give me my phone number again.
This has been a major headache, and I don't think this will actually work fully on my device.
Curious to know if you know why I had to input a PIN after flashing that modified firmware zip after reboot?

Can't say about Sprint usage and AOSP ROMs or sprint anything really so can't comment on that.
After flashing the firmware it wiped my system so it had no ROM to boot to, so I had to hold volume buttons and power to get into bootloader and then ran the VZW RUU.
I have been using multirom personally since this method as well.

I still wish someone would find a way to get AOSP working on Sprint firmware.
After wiping modems, updating PRL and Profile, I have a working phone again on Sense.
I'm not sure what flashing that zip did, but I'm thinking it changes the internal partitions of firmware, and that Sprint either blocks partitions or doesn't have them, and the zip modded them, or added them.
But WTF do I know?

As I. It seems once/if theres a fix for Sprint, it should also hopefully be the same for Verizon.
Your input is as good as the rest of us.

I've gotten CM/Lineage to work on my Sprint HTC 10. I did have to flash an international firmware zip to get it to get past the boot logo but now it's fine. Note though that I did delete the modems, radio, cache and recovery out of the firmware package before I flashed it. This is likely why you have issues with data now if you didn't do so.
That said, data is still iffy at times on AOSP without toggling some settings after rebooting so it might be worth it for some people to wait until that's fixed before proceeding.

How?

New carrier unlocked GSM M8

This is the first carrier unlocked phone I've purchased. It's brand new and I bought it because I'm an M8 fanboy and my first M8 is dying. I'm on AT&T. I just got the phone and installed my SIM and setup my google accounts and all that stuff. I want to update Android but when I go to setting/about/software updates all it says is "checking". It's been checking for over an hour. Did I do something wrong? Is there a way to get the latest OTA Android for an AT&T M8?
My plan is to get to MM then unlock the bootloader and flash TWRP so I can start flashing custom ROM's. I never did anything to my original M8 but have done rooting etc on my old HTC Vivid and both my ASUS tablets.
Thanks in advance for your help.

First, thanks for your reply ckpv5.
Second, not sure I'm following you. I can connect via ADB and it show this when I use the devices command:

Is that the correct ADB command or am I just doing it wrong. Could you please provide more information. I'd really appreciate it. This is my first carrier unlocked phone so I'm a noob at this.

Download this RUU.zip
Rename it by deleting everything in name of the .zip except for 0P6BIMG (and .zip of course)
Place the renamed .zip onto your extSD card and put it into your phone. (the card must be formatted to FAT32 for this, and if it is 32gb or less, it probably already is)
Boot to bootloader and follow the prompts (vol up to confirm the flash ~ power button to reboot after it's flashed)
And that's it, super easy.
Make sure to delete the renamed .zip after the flash, or every time you boot to bootloader it'll try to update again
Good luck!

Awesome. Trying it now.
Can you school me on the information that I posted? I'm used to messing with WiFi only tablets and this is my first time messing this deep into a phone. I don't want to brick my brand new M8 so I'm going real slow.
Here is some more info if needed. I see it says s-off, is that correct? Also, once I update can I then proceed to flash TWRP and custom ROM's?

Thanks. Updated to Android 6!!! Now beware I'll have a lot more questions.

Cool! glad I could help.
A little info: since you are S-Off you shouldn't need to unlock the bootloader before you flash TWRP and ROMs, S-Off is all you'll need.

So it IS s-off! Cool. Any way you could tell me how you knew what RUU to use? Just trying to learn.

Your version-main in your getvar/ OS in your bootloader is your current firmware version. To find what you need for updating, the third series of numbers is what is important to match. In your case that was 401 which = WWE/Interanational
But that won't matter with your M8, only if you get a newer HTC device. The RUU I linked you to is not only the latest, but also the last firmware/ROM update for the M8. It won't be updated anymore and hasn't been for almost a year. In general, manufacturers and carriers will only update a device for two years.

Understood. I have one more problem. My mobile data is not working. I checked all the APN settings and all of them are grayed out. Any ideas on what to do? I'll post a screenshot in a while. Just got to work.
I also tried *#*#4636#*#* but I really don't want to do anything with that yet as I really don't know what to do there and don't want to make things worse.
Texting and phone calls are working just fine.
Well snooping around the internet at work tonight I was able to figure out that I need to set my APN setting. More snooping and I found an APN setting that works......kind of. It will not go 4G LTE only HSPA. Here is a screen shot and the APN settings that get me HSPA.
I will try and duplicate the APN settings from my old phone in the mean time does anyone have a known good 4G (or 4G LTE) AT&T APN that will work with this phone? Hopefully I've posted enough information for the experts to help me get back up to speed.

Either of those APNs should work fine. Literally, the grayed out one (nextgenphone) is the one I'm on now, and it works flawlessly for me (3G, LTE, MMS, etc.). The one you entered (ATT Phone) I believe is actually the new/current one being used as default on most newer ATT phones, and should work fine as well. Your problem isn't APN, I think it's the RUU you used.
I would suggest using the AT&T RUU 6.20.502.5 from here (see RUU section): https://forum.xda-developers.com/showthread.php?t=2751432
Note the red text below the RUU. If you get Error 155 installing the RUU, you'll need to fastboot flash the firmware, before the RUU will install properly (peculiarity of US Marshmallow RUUs).
Reason you need the AT&T RUU, is that by flashing the Euro RUU, you installed the Euro radio, which is only intended to support LTE bands 3, 7, 8, 20. AT&T uses LTE bands 2, 4, 5, and 17. Therefore, you are missing support for every LTE band used by AT&T (the band or bands used by AT&T in you local area being the most important), and explains why everything works but LTE.

Great information redpoint73. I'll flash the other RUU this weekend.
Please bear with me, when you say flash via. fastboot you mean using ADB and pushing it though USB from my computer? Forgive me but as I said this is my first phone I've messed with this deep. My experience has been on ASUS tablets and most of the custom stuff done on them is usually flashed via SD card (or internal storage) 99% of the time. I can do it with the help of XDA I just don't want to render my new M8 inoperable.

If you read the red colored note regarding Error 155, under the RUUs in my Index thread (which I linked) you will see another link there, to a separate post/thread that will tell you exactly how to flash the firmware (if needed). Follow those instructions, and you will be good.
Flash via fastboot uses your computer and USB. But keep in mind that adb and fastboot are similar, but not exactly the same.

I see the RUU you suggested is an .exe file. Just connect via ADB and run that file? Also I downloaded the firmware you suggested as well. To avoid any issues should I flash that first before the RUU?
Thanks

Just hook up your phone and double click on the download. The .exe will install a lot like software for your PC
If it fails to install booting to bootloader first before starting the RUU.exe sometimes helps.
On HTC's US website, there are both manual update instructions and a download for the RUU
I'm not sure if you'll need to flash the firmware first since you are already on Android 6, but it couldn't hurt to do so, and you might actually need to.

Awesome, this place is full of great people willing to help. I just wish I could reciprocate more.

It wouldn't hurt to flash firmware first. Only reason I would suggest folks to run the RUU first (and see if it works) is because not everyone is comfortable using fastboot commands to flash the firmware (and therefore may avoid having to learn how to do that). But if you are comfortable with the process to flash the firmware (it's not hard), then go ahead and do so before running the RUU.
Like xunholyx, I'm not sure if you need to flash the firmware first, or not. If you were coming from Lollipop, you definitely would need to. I have a feeling that you will indeed need to flash the US firmware before the RUU will install. Even though you are on Marshmallow firmware, it's the Euro one, so I think (but not sure) the RUU will still fail until you flash the US MM firmware.

EDIT - Forget it I found it........duh.
Thanks redpoint73. I'm going to flash the firmware first because of what you said (Euro phone vs. US).
I can't seem to find your post on how to do that again in the sea of posts. I thought I bookmarked it but it's not there. Can you be so kind as to link it up.

No service on HTC ONE M8 (no network signal bars or emergency calls only)

I'm not an expert but I'm not new to this either. I just don't have enough technical experience to figure this out. I had the Phone working and everything was amazing!
A few Days ago due to flashing the phone came up with a message 'No service' and i cannot get the phone to connect to my network at all. The phone cannot make emergency calls yet it cannot connect to any of the networks. When i turn off the Airplane mode it just get stuck on it and it never gets off even if you leave it for a day.(Check screenshot attached) When i dial this code *#*#4636#*#* nothing happens. I don't get the information although The code just vanish away from the dialing screen.
So far, Ive checked both covers on the back ensuring the pins connect properly for the aerial and there is no damage to either panel.
Hard reset did nothing to help, it booted straight up with the same limited service message.
I have tried my SIM card in another phone and it works perfectly, so i know its a problem with the phone.
I've had the IMEI number checked and the phone is not blocked.
The SIM card appears to be detected as you can see in the screenshot i attatched.
If the phone had been dropped, gotten wet or experienced any other form of potential damage, then I would assume it was a hardware repair issue. But because nothing has happened to obviously explain the issue I am experiencing, I am unsure.
Any thoughts would be greatly appreciated!

What exactly did you flash (include file name, any version number, etc.)?
If the "no service" occurred right after flashing something, than that is mostly likely the cause, and the road you should pursue. Not things like checking IMEI, etc.
Tell us exactly what you did, exact sequence of events, etc.

First of all i want to Thank you for replying. Actually one of my friend Flashed it i have no idea what he has done even though he don't get it but he flashed it somehow and made my device in this Position.

You need to ask your friend what he flashed. It's extremely important. Ask him what file, with the exact file name, version number, and source (whatever of those he can give you, all of them if possible).
It sounds like he doesn't really know what he is doing? Why did he even flash anything at all? What was he trying to do? He shouldn't be doing anything to your phone, unless he intend on buying you a new one when he messes up (and it looks like he did).
Seeing as the phone is s-off, it's very possible he flashing the wrong file, and damaged the radio. The damage might be permanent (we've seen it happen before).
Also, we need more info about the phone. If you know how, do fastboot getvar all, and post the results (delete IMEI and serial number before posting).

He is a complete noob but act like if he is a Pro ( I came to know after he did this to my phone and when i forwarded him the Questions you asked)
Actually my Phone was a bit laggy which made me pissed off and my bad luck was that he was sitting right next to me. He told me to leave my Phone for a day and he would fix it up at the end result is in front of you.
He have no idea what he has flashed i.e. (exact file name, version number, and source). He said i downloaded from a random site by searching it from google. LOL!
I will give you the info whatever you want to know.

That type of behavior is extremely careless, and my opinion, that person should not be messing with yours or anyone else's phone.
If he had truly "no idea" what he was flashing, then he had no business flashing it! Him having "no idea" what he flashed to me says he had little or no understanding of what he was doing. And best practice is to fully understand what you are installing to the phone, and also keep track of exactly what those files were, steps performed, etc.
The file (or files) that he flashed still aren't on his computer in a folder somewhere, or even in the PC's recycle bin? Another best practice, I always keep files (I've flashed) on my PC for a while "just in case" I need to use them again or reference them.
Really hard to troubleshoot the problem, without knowing what he did. One thing I can suggest, is to flash the RUU, which is a complete factory image, and will hopefully clear up the "no network" problem. See the following post for files and instructions:

I'm forwarding all of your Messages to him. He is ignoring them he ain't answering my calls either. I cannot contact him right now. I don't think whether he have the files anymore.
Anyways, apart from that is there any other way to Flash it back to the normal state?

Leave it S-Off till (if) you get it up and running. Then its entirely up to you.
Looking at the bootloader screen. It appears as though it is a faux bootloader as the status is official.. Cid is 11111111 which is supercid, so be careful.

If flashing can damage M8 radio files then there might be a file that can fix it also. What do you say?

If there was such a file maybe. But such a file does not exist (not that I know of) or it's not available for the general public.
