[Q] Please HELP unable to make calls- No sound in-out after upgrading to JB LT4

Hi all,
Last week I upgraded my Note to new LT4 rom.(s). Couple of days later, my Note was unable to make calls. When I try to make call or receive a call, there is no sound neither from earpiece nor from the speaker. If I reboot the phone I sometimes be able to make some calls with a great noise on the background then it stops.
I re-flashed the rom and flashed other roms even re-flashed LZS roms with all clean install even finally formatted the internal sd card . No change.
Since I can make one-two calls after each reboot I still think it may be a software issue rather than hardware.
All other functions including cell reception, 3G, internet, wireless all working very well but cannot use it to make phone calls.
If you have any suggestions I appriciate.
Best Regards
Update - I installed the stocked LZS Rom but the problem still continues.

have you checked that your IMEI is the correct one? maybe it got corrupted...If that is the issue, should be solved by restoring your EFS backup .

No, I haven't checked. But I don't know my previous IMEI . How am I supposed to know if changed or not? I haven't backed it up. How to restore to original status?
Thanks

Below the battery you have the original IMEI number...if it is changed, then that is the issue. If you don't have a backup of your EFS, I am not sure but you can try to flash the stock rom by selecting EFS in ODIN PC. That is stuff is quite delicate, so I would recommend you to ask Dr. Ketan that he is more familiar with it.
But again, make sure that your imei is fine first. If that is not, then might be a hardware issue..

Thank you for your kind suggestions. I checked and it looks O.K. there is no change on IMEI. Actually I can receive SMS and 3G is working very well, my phone rings if someone calls but cannot talk.

Problem continues
Hi There,
The problem still hasn't been solved. Somehow all is going fine and suddenly re-occures. Has anybody come up with same problem and found a solution? Please share.
ı am on xlt6 Rom with Philz kernel

Phone doesn't read my SIM

I have been using CM11 (14-03-2014 I believe), without major problems until yesterday. Sometimes my phone seemed to disconnect from my SIM and I had to re-enter my pin code to reconnect to my operators network. But as of yesterday my device doesn't seem to recognize the SIM card, It doesn't ask for a code at all and can't make any connection whatsoever. I didn't change a thing, this problem started out of the blue.
I wiped cache and dalvik, updated to the latest CM nightly (08-05) but that didn't make any difference. In other threads I read about the baseband that might need an update, but I can't check which version I have now because when I try to enter the hidden menu I get the no network connection error. The strange thing is that CM11 has worked with (I guess) the stock baseband.
Is my phone tripping or could it be that my SIM card is broken?
Help and thoughts will be very much appreciated

Try it on stock to be sure about it.

After some searching I found a phone that could fit a regular SIM card, a Blackberry 9900. My SIM worked perfect in this phone, so that is not the problem.
I Also did a complete wipe and installed a stable version of CM 10.1.3, but that didn't seem to help. I hoped that a downgrade would have done the trick. I might try a ICS ROM or the stock firmware, but I kind of lost hope and i'm starting to think this problem is hardware related in stead of software. I'll report back with results on stock firmware and the ICS ROM.
How can I make sure the SIM reader in my phone is working properly?

Sorry for double posting, but I got an update:
SIM wasn't working with ICS so I decided to go back to the stock ROM. However, when I tried to flash V20B.kdz with KDZ_FW_UPD, the program got stuck at wParam=2010 and iParam=210. The phone is now stuck in S/W Update mode, and I haven't found a way to restore it yet. I will argue a little more with my phone when I get back from work, I'll open a new thread on how to unbrick when I can't do it myself.

I too had some problem with last R13 update:
- Contacts in SIM are no longer seen, so they can't be transferred to phone,
- Found WI-FI and mobile network turned off, may airplane mode have been set on by itself?
Now went back to R11

Brightness issue
Hello, loving the ROM so far!
Only thing I dont know how to solve is max brightness after I reboot the phone (I have set mine to minimum).
It gets back to minimum after the screen turns off or after I manually set it off.
I tried factory reset, didnt help.
Thanks for the help!

upgrade new rom
Hi,
last week i installed this version
20140910 Release 12 on my samsung galaxy s plus
followed all steps from the openings post of this thread:
http://forum.xda-developers.com/showthread.php?t=2579431
I used CWM.
My question is with steps should i take if i want to upgrade to
20141011 Release 13 [EOL]?
Thanks a lot

First you have to update TWRP to 2.8.0.0. from there you can flash R13 and reboot.

Installing CM11 rel11, serial disappeared - best way to restore?
Hi folks!
I've upgraded the stock firmware to CM11 rel11 from this thread on a i9001. Now it is on EOL rel13.
By the initial upgrade I assume the serial number turned unknown, so now I am only able to make emergency calls. Until now it didn't make me upset at all, however recently my priorities have changed. (In a nutshell: VOIP telephony was kicking in, thus it would be handy to turn my GPS device a 3G and callback capable... well... phone.)
Before the upgrade operation I followed the recommendation and created a backup of /efs and /persist. Not surprisingly the backed up and current images of these partitions do differ on some bits. However at this point I became a bit confused, and teh internetz didn't answer (yet?) my questions:
- Shall I simply dd the original images back, reboot, and problem is solved? Or doing so I will brick my precious device (being even unable to restore the current state of these partitions) thus lose even navigation?
- Is there any better restore tool around that supports i9001?
- Am I totally off track, and should make some other magic? (Like using some 2013 patch that kicks out S/N check, etc.)
Thank you in advance!

Project dead?
I have tried to download R13 files. All downloads hosted by devhost failed because the files seem to be unavailable. Tested with Chrome and Dolphin on i9300 and i9001.
Can you or someone who has already downloaded the files please provide an additional mirror?
And why is R13 EOL if there is no clue of a newer Version? Have you stopped the development completely or are you preparing for Lollipop?

I have the same problem as PsychoGame
"Hello ADC-Team,
First of all thank you for all your hard work on this device, it's much appreciated.
Second I want to report a small bug which I've encountered and am unable to get past. I followed the next steps in flashing:
I flashed TWRP 2.8.0.0 on my Samsung Galaxy S Plus.
Rebooted into TWRP 2.8.0.0
Completely wiped the device (Cache, Dalvik Cache, Android Secure, SD-card, System & Data)
After full wipe installed the cm-11.0-20141011-ION-dev_connection_team-release13-ariesve.zip
After flashing CM11 installed GAPPS package
Cleared Cache and Dalvik Cache once more
Rebooted and set-up device
After the device has been set-up I'm unable to use the contacts app for some reason.
I've tried clearing Cache/Dalvik Cache and Fix Permission but this error still persists
Reflashed the CM11 package again but still no luck, the error still persists.
Does anyone have a suggestion, or is anyone also facing this same problem?
Greetings PsychoGame "
I'm unable to open my contacts, i din't have the problem with release 12. Is there a know solution?

Yes I share the same problem, as said in post 21 oct 2014 at 07:30 PM.
I can't use the contacts because they can't be read in the SIM and can't be exported to the thelepone memory.
Tried with wiping, cleaning, etc., but I had to step back to a previous release (R11) very well working.
Looking at the lenght of the files I could see that R11 is 210.888 KB, R12 is 211.708, and R13 is decreased to 189.921.
Something lost

I don't share this. The contacts are properly downloaded from Google and I can access them normally. I can also add contacts and save them!
Edit: were did you save your contacts? If you've saved them on your sim card, I'd suggest an app called 'sim contacts'. I found out I had some very old contacts stored on the sim card! I almost forgot this possibility...

I reinstalled the rom and gabs again in my pc at home and the problem is gone. I have another question I like the english language on my phone because if there is a problem and a solution it is mostly written in english. I live in the Netherlands, i tried language english us but that gave problems with reception. My provider signal (t mobile) disconected sometimes ramdomly. My solution was select english united kingdom instead of Dutch and Nederland. My question about that solution is: Is it possible that i have slighter worse reception than if i select country Netherlands and language dutch of shouldn't that change make any difrent i means of reception signal strenght?
Thanks for the fast response smitharro

I don't think the language settings of your interferes with the signal of your provider. I always use English with Kpn..

Hello folks,
I still am having problems with contacts from SIM.
To make short a long story:
-1-I have my contacts (216) in SIM.
-2-I must have them in SIM because sometimes I have to put SIM in other phones neither Android nor Google.
-3-That means I do not save my contacts in Google Cloud.
-4-CM11 doesn't use SIM directly (R/W), so I used to select all contacts in SIM and transfer to Phone Memory (not in Google Cloud).
-5-I could do that until R11 and R12.
-6-(Note_1 : before an update I perform a total wipe and a factory reset)
-7-Now I installed R13 with the same procedure: factory reset and instal ZIP
-8-The transfer of contacts is not possible because contacts in SIM are no longer visible,
-9-If I install R12, copy contacts to phone, then install R13 on it without erasing nothing (cache, dalvik, reset) then i can see contacts previously transferred under R12.
Note (tried as suggested by smitharro) "sim contacts" from market. It Reads and Writes contacts on SIM, but cannot transfer to Phone, I get this message "operation failure. try again".
My question is: how can I transfer contacts from SIM to phone under R13 as per step -7- and not pass via step -9-?
I may make something wrong, but do not understand what.
Help please
Many Thanks

I tried to copy one of my old contacts from the Sim to the phone with 'Sim contacts'. It works perfect! The contact is visible in in 'contacts' after this operation! It isn't visible when it's only on the Sim card however... Sorry but I'm afraid I can't give you a solution for this, other than just use Android phones...

Hello people,
Thanks smitharro for the test you did with "sim contacts" with R13.
It doesn't work with me; if I try to copy with "sim contacts" (by Needom Studio), it gives me the message "Operation Failure" and stops.
BUT
Then I tried with "sim manager" (by Robotobia) and all was perfect: I could copy from Sim to Phone and from Phone to Sim.
(Info: my sim operator is WIND, memory capacity 64 KB)
I hope this could be useful for other people that might have same problems.

Glad it finally worked out for you! I used the Needom Studio app. That one worked fine for me. Don't know why it didn't work for you. Most important: your problem is (somewhat) solved, although it's just a workaround. The Rom still doesn't read the sim-contacts 'by itself'. For me, personally, that's not an issue. Hope the rom will be made 'perfect' before it reaches it's real EOL... On the other hand, nothing in life is absolutely perfect! remember: this rom is brought to us absolutely with no charge by people who volunteer to do this development, just because they like doing this.

Still confused
Hi again
I'm still confused, whether it is safe to dd my saved partitions back to restore my serial number. (Still not 100% sure if these partitions are bound to a particular firmware revision, e.g. only usable as a source to harverst my serial from, not to restore anything; and neither 100% sure if dd is the best tool to rewrite them.)
Having no - even a short - answer means I am asking something pretty obvious? By my opinion if it were obvious, google had answered it already - but it didn't.
Any answers appreciated.

First of all, your question is not fully clear to me. What doe you mean by serial number? You're IMEI number? If you've lost that, your phone is nothing more than a small tablet. This is a unique number to identify your phone on the provider's network. So you'll have to restore the backup!
The serial number in my phone however is 'unknown' in the rom. But the rom works fine! There's no need to have that for the use of this phone. I don't know where it was stored in the original rom, but be very careful with messing with the 'EFS' partition!

Thank you for your reply!
My IMEI number remained well, however I learned that both IMEI and serial (S/N) is needed to have a phone (e.g. to connect to carrier) instead of having a tablet.
For example here is said: "IMEI is showing now but still no calls and sms. I also noticed that the serial number is not the same as the one written at the back of the phone. I have read that restoring EFS solves this problem".
There is also some magic ("azira patch") to S3 that states the same. It operates by bypassing serial check, but since it is old (2013) and originally for S3, I'd rather stuck restoring my /efs partition.
Backing up /efs is written down everywhere. Restoring it... well. Mostly external tools are mentioned, that don't support i9001.
Even further, suppose restoring /efs and /persist is the solution for my problem, I think I know how to do that. At least by dd. What I don't know is that the structure of these partitions is fix or may change between Android versions. And of course: if I rewrite them to original, will my device boot again?
Considering these, any idea if I'm off track, or not?

I never touched my /efs partition nor will I ever! My phone is running fine without the serial number displaying in the rom! I can make phone calls, send text messages and I have mobile data! So you really don't have to restore the serial number. Possibly it's still there and still used by the provider, but is the settings app simply not reading it... Sorry I can't help you more. I'm not a developer, just a user...

- Tried to flash and wipe the latest nightly without luck
- decided to try the V20A kdz and it works again for few restarts (root and stuffs)
- Tried kdz without doing anything, just restart. After 3 restarts, lost IMEI again.
Thank you for your time and thank you in advance.

I had the same problem...
In my case, as far as i can tell is hardware related.
The connection (imei and baseband) returns only if i use brute force, and start to press the phone very hard near the edges, near the the sim. .But they disappear if i turn off or reset the phone...

Is hard to take pictures because this is not a tutorial, i press different parts every time i lost my imei, until it works. What i do is pressing really hard (even bending a little the phone) everything above the battery, especially the sim card holder. Sometimes take 5, 6 , 7 attempts until the signal returns. When the phone turns on wait a little, because takes a few minutes until the signal returns.

I have kind of the same problem, but with slight differences: if I restart the phone, most times than not I get the signal back (at least for a few more hours) and using Zaiben's RC17 ROM it manages to get the signal back by itself after a while, no reboot needed. What I've found to be a "hack/solution" for this problem is to use the app Tasker to change network mode from 3G to 2G when the screen turns off. It appears than while in 2G this problem doesn't present itself...

@sergiohinniger apparently your brute-force method kinda works for me as well.
My phone started losing IMEI and baseband version after I replaced the audio jack and "small" PCB (the one with USB - now I'm back with original one). I then re-chcecked all connectors and coaxial cable, but the issue persists.
I think it works after few reboots with pressure on the back, so I believe that most likely it's caused by some bad cennectors. I have no idea though what to do with that Help, anyone?

It's true, with Zaiben or any stock roms the signal returns far more easily and sometimes resists the reboot. But now i have a new problem, the mac address, even when the signal returns, stay 00:00:00:00:00:00. I can only fix with a mac spoof app. This problem doesn't happen when i use custom roms, but the 3g signal is harder the return.

Some news, bad news
I have asked some repairers and here is their answer:
It's baseband file problem, if you have original Nandroid backup then it might help otherwise you can say bye bye to it

basically, the baseband/IMEI file is damaged due to flashing rom, if you dont have origianl file, there is noway to save it

Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)

I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)

A repairer told me that some rom might contain RIL or baseband bugs that accidentally **** up our IMEI partition/files, so if you have NANDroid backup then try to restore it

[Q] Xperia Z c6603 Sim card not detecting problem

Hello Friends,
I am sorry to create this thread if already a discussion going on under the same topic( I am that much frustrated as well as desperate). I updated my set to 10.5.1.A.0.292 few weeks back & when it reboot I get a popup window saying nfc firmware update error 000004 which is present till the date. Then it starts a new issue like loosing the signal and reinserting the sim card rectifies the issues at first. Few days back it completely lost the signal & a sign appeared on top right corner like a red "X' mark with sim card.I tried to reinsert the sim and when I does the set shows 'sim card inserted , restarting' but after reboot again no signal, when i removes the sim again it popup as 'sim card removed, restarting'.
I tried many other sim cards. Result is same though all are working in other phone. I tried every thing starting from factory reset to flashing using PCC as well as Flash tool but still the problem persist. When I flashed CM 11 and searched the set shows all the available networks ( Though no signal was showing in status bar) but fails to register in any of them. Any idea what happened to my set and is it curable. Please help it doesn't have warranty.

does it work for CM11? maybe there is something wrong with your hardware, check what does it display on baseband, maybe try a reflash once again.

Hello Zennis thanks for the reply. I tinstalled cm 11 on it and then also there is no signal bar in the status bar but under mobile operator option i was able to check the network and all the available network were showing there but when i tried to connect my service provider it failed. I dont think there is a hardware problem coz i use it that much careful and hardly 5 minutes before this issue i attended a call.
Looking forward for your valuable reply.

I think its a baseband problem.... I previously faced problem like no signal,no imei,no wifi, etc...then i flashed different version of stock .ftf
And my problem was solved.

Hi puneet its sad to know that you too are in same situation. As I said in my post the unit was functioning for about several weeks and suddenly it fell into no network state again and this time all my trials went vain. I just sold that unit at a cheaper price to a mobile repairing shop. i dont know what they have done with it. In my opinion dont waste your energy for xperia crap.
Thank you & sorry that i cant help you.
