My defy is gone to meet his maker

Well, I thought I'd let you guys know, my defy went to the official motorola service, now, before someone starts posting "room full of people who cares" pics, I'll tell you what where it's symptoms and maybe you can tell me if any had any similar issues.
A little background:
I'm in Argentina, and I got my defy from "Personal" ( that's the carrier) which has a 2.2.1 rom ( if I'm not wrong )
I used it for a bit and it was working so well that I didn't feel the need to mess with it.
Then, I started missing some stuff and I decided to install CM7 (rc1, v2), to see how it performed.
All good, for a while, but then, the following started happening:
- 5~8 times out of ten, sms's wouldn't go out ( and I had to re-send them until they did )
- I got delays on getting messages, and on other people receiving them.
- Sometimes I wouldn't get to answer a call, just got a "missed call notification SMS"
- Sometimes calls would drop when answering them
- FM radio started being CRAP, and getting either stuck on, or wouldn't turn on after being interrupted by other notifications.
- frecuent freezing .
I guessed it was CM7, so, deceided to get back to stock, and maybe rooting, just for kicks.
I went back to stock, but the problems kept happening.
And that's why I sent it to service.
Anyone got any similar issues?

I wounder if you had forgot ‘full wipe’?

This sounds like an intermittent connection somewhere in the phone hardware.

lol, of course I did wipe, I didn't got into GREAT detail of everything i did because it would be WAY to boring, but, I did tried a lot of stuff before sending it back.
I kind of know my way around android, but I don't blame you for asking, I've seen a lot of uninformed posts around here ( nothing wrong with that, not everyone has time, the patience, or the interest to spend HOURS figuring stuff out, and learning about android )

Yup, I also thought it could be either a SEVERE overage problem ( like a signal black hole in my apartment) , or a defective sim card , but I'm using my old HTC G1 for now, and it's working great, so, both of those are out.

Maybe ,your phone’s baceband does not fit for the sevice,download some app to change the baseband.
Many peope have the same problem reflected by forum in my conutry as far as i know. Most of them solve the problem by changing baceband.
(My english is so bad...but I really want to help you.)

If the baseband was incorrect, it wouldn't get signal at all.
Plus, the phone was bought in argentina, so the argentina stock rom for the carrier HAS the right baseband, and I still got issues.
I have no other explanation for it than faulty hardware.
Thanks, though, I know you're trying to help ; )

Sim not detected.

Phone arrived yesterday for my partner and after a lot of fun and laughs with the the update bootlloop ,it just gets better.
After fastbooting latest Elephone rom from Needrom,everything works well except I can't phone.Put in my Virgin T-Mobile sim ,not detected,so cut down a nearly year old Asda freebie mini sim from EE,still not seen.Both working well in My Doogee Dagger 550.Have heard some having problems with Virgin, but this phone should be ok .
Thinking of trying another rom ,tried Eragons did not put a sim card in, but thought partner would prefer more vanilla rom.
Any help please as partner going through a very trying time at mo,mum not well.

Any help please,never seen this before,just blank in both sim holders when sim card inserted .Presume even if wrong sim for phone it would show something.
Seems it may be hardware?
Wow problem solved ,reflashed rom again ,still not there read about disabling all added apps and on power on jab volume down button and sim know seen .
Relieved an understatement,and now to bo bos well after drinky poos.

Hi morrig. Please can you be more specific in your steps here? How do you disable all apps and in particular, at which point do you 'jab power down'? All I get is the Chinese recovery bit :/
I have successfully managed to revive my phone using the '909' ROM but like you and many others, my SIM isn't being detected in either slot.
It's a frigging shame really. The P8000 is a great phone in my opinion let down by shoddy developers and lousy customer service. I hope Elephone get it sorted soon.
Cheers

Have'nt a clue why it worked initialy,lost sims again.
Only work round was to flash Elephone rom 7/25 which has the right kernel to support sim,then flashed recovery and intalled Eragon rom.
Then found yesterday morning that after on charge all night battery nearly flat,partner(whose phone it is) was spitting blood.
Problem fixed by wiping cache,then charged well.
Cracking hardware and value,rubbish software, thankfully being solved by great developers.

EXCELLENT! Cheers morrig! 7/25 does indeed return the use and detection of sim. Thanks very much :good:

That;s weird.. I have a similar issue.
Been trying out a bunch of ROMs - well, Nexus and Eragon and Stock.
Nexus won't detect my SIMs at all and the other 2 detect them but can't make a call (can send a text oddly enough... not receive though).
Something to do with IMEI not being picked up.
I flashed 7/25 using SP Tools but no joy.
I did use:
http://bbs.elephone.hk/thread-3088-1-1.html#.VksvG_nhCHs
.. that to manually put the IMEI in but it's a bit odd.
Just gonna try Eragon 6.1/Philz and that weird IMEI 'fix' and see if it works.
It'd be nice if I could just stick the Nexus ROM on and everything worked...

Great danes,you buy a smartphone to use mainly as a phone and without it working its nearly useless.
Did you use Win 7 to flash ,very easy to install MTK drivers ,tried everything on Win 10,did the restart with digital signing,noticed that on Win 7 had two digital signing yes or no yet only one in Win 10.Think thats why couldn't get Win 10 to install drivers properly ,yet others have,maybe because I'm on build 10586?

I used the rom on Needrom,no problems and never bother using nvram backup on install of new rom on my DG550 or the Elephone.
http://www.needrom.com/download/p8000/
Just to add don't try Eragon 6.1 its beta and some have sim problems ,use 5.9.2,that's the one that works.

Yeah, I've installed 5.9.2 now.
Basically, I put in the IMEI manually, used *#*#4636#*#* to enable the radio and the 4G works now. I can make and receive calls.
However, I can't RECEIVE texts (standard SMS). I can send them but not receive.
Why do you think that would be?

M8 can't receive calls, flashed wrong ROM? (4G problem)

Yesterday I flashed my AT&T HTC M8 to a custom ROM (Wolla) because my phone was really laggy after the Lollipop update, and I noticed that although I am still able to make calls, I cannot receive calls anymore. I am wondering if it is possible that I messed up a step somewhere (especially step 3), or if I flashed my phone with the wrong ROM?
I also looked around on XDA more, and realized a few people also had this problem, and it was resolved by turning 4G data off. Apparently this is a problem with AT&T activating Voice over LTE, and the custom ROM not supporting/compatible. Is there a suggested fix to this problem (eg. flash back to the RUU on HTC's site)?
Here are the instructions that I followed to flash the new ROM:
Unlocked my phone via the HTCDev website
Installed TWRP
(Here is where I think the problem occured). I downloaded the Wolla Marshmallow ROM from the XDA thread, and took the boot.img image from the .zip into my fastboot folder.
Then in fastboot, I typed in "fastboot flash boot boot.img", then "fastboot reboot" to reboot my phone.
HOWEVER, my phone would be stuck in white Android booting screen, and wouldn't move for around 10 minutes, so I thought it was stuck.
I redid step 4 a few times, but the same thing always occured.
Finally, I decided to take the boot.img file from an RUU from HTC's website, and use that instead of the boot.img from the Wolla .zip file.
Now my phone boots, and everything seemed to work.
The only issue is that although I can make phone calls, I cannot seem to receive phone calls. It doesn't "ring" on the caller's end, and goes to voicemail in the end.
Does anyone have any experience with this?
My phone is an HTC One M8 bought from AT&T, unlocked about a year ago.

You're on the right track (AT&T's deployment of VoLTE is the problem), and there is one more suggestion I can make: call AT&T and have HD Voice (their branding of VoLTE) turned off for your account. Details here: http://forum.xda-developers.com/showpost.php?p=62001970&postcount=28
Not a true "fix" as obviously, you will not have VoLTE if you do this. But its not a bad compromise, IMO. Not may folks are going to miss VoLTE, and at least the above workaround will allow you to use the custom ROM you want, and have LTE data.
Your other option, is to use an AT&T-based ROM. But who the heck wants that?

I think I'll hit up AT&T chat support today to turn it off, thanks!
I'm sure there are a lot of other AT&T users using custom ROMs on the HTC M8 on this forum. Are all these people getting this problem too, or are they using a special ROM that doesn't run into this issue?
Edit: I'm also a little worried if this problem might occur on other 4G networks internationally? I tend to go abroad once or twice every year, and have a SIM card for the other countries I go to. Is this an AT&T specific issue, or would I run into this problem for every country that also uses HD Voice?

Note that the base level customer service probably can't turn off HD Voice (won't know what you are talking about, or even wrongly claim it can't be done). Ask to talk to a Tier 2 (or some such term) tech support.

If you click on the full thread, for which my previous linked post is from, you'll see that there are a good number of folks that had the same issue. And that is just on that one thread, there have been others (like this one of yours).
Plus, there are other variables that will effect whether AT&T users (on "international" based ROMs) will see this issue or not, such as whether HD Voice has been deployed in their market or not (heck, lots of places don't even have LTE yet, much less HD Voice), or whether the HD Voice feature was ever turned on for their account.
Personally, I have yet to see this problem, despite being on several different non-ATT ROMs and frequently travelling to various US regions. So I'm guessing in my case, HD Voice was never activated on my account.

From what I can gather, this is entirely an AT&T issue. Although nothing is a sure bet when travelling international, I'm sure you probably already well know if you travel abroad occasionally. In particular, LTE implementations seems a lot less standardized from one country to another than 3G or 2G. But falling back to 3G is not a bad option, if you end up needed to. Really, unless you are streaming video a lot, or downloading huge files, 3G is really all you'll need most of the time.

So I think I found might have accidentally found a way to deal with this problem without calling AT&T.
On my stock ROM, I turned of the VoLTE (HD calls or whatever) options under data connections.
Made a few calls to myself to made sure that it was dropping to 3G (ect...) when I called it.
Afterwards I flashed a custom ROM (the new sense 8 rom by sundream) and my phone could still receive calls as it dropped it for 3G.
While you don't have VoLTE you could avoid the hassle of calling AT&T.

Phone remains unlocked. Unfortunately, it wipes APN data and now I can't go in and edit APN. Anybody have any work arounds? I can't add an APN (no option) in the settings menu (settings - more - mobile networks - access point names) nor in the ##3282# menu with the MSL. It's been a huge pain and I'm currently trying to use this phone in Peru. It can make and receive calls/texts but will not access the internet without being able to add/edit APN's.

But if anyone knows how to do it please i beg you i need help as it was my gift to my father and i fu..ed it up :crying:

Why,LG, why?
Gah this is so frustrating. I had my phone unlocked by sprint and am currently abroad, but had the wonderful combination of ideas to both update to ZVE and reset network settings. I've already been using this international sim for five months and everything was fine and dandy, but now I can't add an APN so I can't connect to the internet (the apn settings are greyed out) - I even spoke to Sprint for 3 hours and they concluded there's nothing they can do. I'm thinking there's one of three things to be done: change the APN by some "hack" like a dialer code or ADB, revert to previous firmware, or connect to the internet somehow without an APN.
Does anyone know how to do either of three things? Please help.
Update: I called LG and Sprint for a combined total of about 5 hours. LG confirmed that indeed with ZVE they disabled manual changing of APNs (due to "security") and they don't even have a special code or anything to fix that. They said I should ask Sprint to maybe push an ota apn for the international carrier but they said they can't do that. The LG guy said that he would add a ticket (they can't even talk to anyone higher up) to tell the dev team to add an option again to change APNs but I don't know how likely that'll be. It's just super frustrating that LG pushed an update to break international data and now says they can't do anything about it. Reminds me of my bootlooped Nexus 5x that they said they couldn't do anything about. Smh lg, smh.

Welcome to my hell. I tried to warn the community in my comment about this exact issue. I spent weeks talking to Sprint and LG's useless "technical support." LG reps kept insisting that LG has nothing to do with software updates which is completely wrong and extremely ignorant of them to think that. Sprint advanced tech support even conferenced LG in on a call once that lasted about 45 minutes and the LG rep kept saying they don't have anything to do with the updates. Finally, we got him to agree that they did make the updates. But, even that was a waste of time. It wasn't until I wrote to LG through their website that I got several responses (mostly the same as before - walking you through how to change APN settings) but, finally in those conversations, I was able to get LG support to admit that they had a problem with ZVE and that they are the ones that broke it. The last response I got was that their developers are aware of the problem and are working to fix it. It probably won't be fixed until the next software update and they won't give me any timeline as to when that will be. It's been a couple of weeks since I last talked to LG. My advice is to do the same and file a bug error on their website. Calling in is a complete waste of time. They need more reports on this so that they know this is a big issue. You can't even go in with your MSL and change APN's. If they were really worried about security, they would at least allow the carriers to give you permission to modify the APN. Seems completely nonsensical to me.

Never update if you have an unlock. I've said this a hundred times... Maybe you can get on eBay and get a remote unlock.

How does one file a bug report? I looked and couldn't find it.
As to the reason I updated my phone, I'm very involved in security and need the newest security patches I can get. Also, I don't know/don't think a remote unlock will help, I think it is actually fully impossible to add an APN at this point... I even had sprint lock and unlock my phone...

Sometimes you can't have your cake and eat it too. A bug report will get you nowhere. I've filed legitimate bug reports with solutions and didn't even get a reply. They did this on purpose and don't care if it effects you. They don't want you to use your device the way you want, they want you to use it the way they want.

I read this in other post
Idk this work
HiddenMenuCall
Google, download and install HiddenMenuCall_1.7.apk
Go to LTE Settings
Go to APN Settings
Set APN there and use "default,dun,fota" as APN Type
Restart phone
Done!

VoLTE and WiFi calling

Hi
I am trying to enable VoLTE and WiFi calling on my Nexus 5x. My carrier supports these features, and as far as I know, Nexus 5x is capable of supporting them as well. My phone is rooted, and runs Pixel 2 ROM which I found on xda (https://forum.xda-developers.com/nexus-5x/development/rom-pixelmod-lg-nexus-5x-t3486862). I have Magisk flashed and I just enabled the "VoEnabler" module so that I get the necessary toggles in Settings. They appear, but unfortunately, they do not work. When I check IMS registration in ##4636## (##INFO##) it still says "Not registered". I have learnt that I need to enable a certain "profile" for the Qualcomm radio chip as well, so I downloaded QPST_2.7.460 and managed to see the phone in PDC.exe after installing the correct Qualcomm drivers on my PC, and setting the DIAG PORT to on for the phone by issuing the command 'su; setprop sys.usb.config diag,adb' in a Terminal emulator on the phone. Where I am stuck now, is in PDC, because it only shows me 3 profiles: HW_DEFAULT, SW_DEFAULT and ROW_Generic_3GPP. I read that Vodafone_India, or Telefonica UK, or Telia Finland would be profiles that may work with my carrier and allow my phone to register with IMS, but unfortunately I do not have those in the list. So, my question is, does someone have more experience with this, can I load MBN files for this profiles using the "Load" button in PDC? If so, do files coming from other Nexus 5x, or even other phones work? If anyone has any experience with this, any help would be grately appreciated.
A little update: I tried with some of the mcfg_sw.bin files from the stock ROM, unfortunately, it just cannot activate for Sub0 and switches back to ROW_Generic_3GPP. Furthermore, I downloaded an LG G4 firmware, as that phone uses the same chipset, and tried to see the files extracted from the KDZ file usig 7zip, yet none of the "mcfg_sw.bin" files actually appear in PDC so I cannot "activate" it on the phone. Would really appreciate someone with a bit of experience to guide me on this one.
Thank you very much.
PS. Sorry if this is the wrong section, feel free to move it wherever it belongs to.

Your carrier needs to have enabled these features in their network for your phone model, too.

I've found that support for VoLTE is very spotty among custom ROMs. Some don't seem to pay any attention to it, some say they "support" it but it doesn't seem to work. That may be a per-carrier issue. FWIW I'm on Verizon in the USA and CandyROM is one of the few I've found that "supports" VoLTE, *and* it actually works for me, *and* the ROM is actively maintained. So maybe try that one if you're not too attached to PixelROM. I wish this feature was paid more attention by developers, it really makes a big difference in call quality.

The carrier supports it, of course. Do you have the same phone (5x) and run CandyROM on it? Have you got a link for it? I don't see how ROMs really have to do anything special, since they do not touch the radio partition, which is still the one from stock. You just have to add the toggles to the Settings app by editing build.prop, I guess. But I will take a look anyway, maybe it actually works, although my carrier does not support this actual model, I was hoping I couod change the modem config on it and force it to work with WiFi calling and VoLTE.

Yes, I have a 5X, run this ROM, and VoLTE works.

Maybe I'll try it, although I am pretty sure it won't work by default on my carrier, since it has the same default radio which lacks the proper config for my network. That's what I am trying to get, a proper config that will work with my phone, by switching it with Qualcomm PDC.
For Verizon, the necessary config is already in the radio image, of course, and probably gets picked up automatically when the device signs into the network. For Europe, all I see is EE UK...

In the UK the operator EE does support VoLTE for many phones but not for the N5X, even if you've "provisioned" it in your ROM.
