No imei on cyanogenmod - Xperia Z Q&A, Help & Troubleshooting

Hello guys,
So i flashed CM 10.1 on my Sony Xperia Z but i have a problem. All of a sudden the phone crashed and when i rebooted it, i had no cell reception anymore. What i've done to make it work again:
- Flash back to stock: no probel with cell reception, evertything works but back in cyanogenmod it fails again
- Format /cache, /data and /system with CWM
- Updated to the latest version of CM
- I called *#*#4636#*#* and tried to turn on the radio in 'phone information' (=> button always says "turn on radio")
- restore permissions in CWM
So what i've found on XDA:
Apparently i don't have an imei number when under CM, but I do have a valid number when using the stock rom. I checked some threads
on XDA and they all say I have to restore the /efs folder (or the nv_data.bin file in it). I checked the root of my phone, but there isn't any /efs folder... So no luck there.
What now? Or is it just the rom that aint finished? What would be strange because it did work.
Thank you for your help

[Help] My X8 reboots once enable Wifi

My X8 phone runs in reboot loop once I turn on wifi. After on wifi, the phone reboot in few seconds. Then, it goes into "Free Xperia" & CM7 logo, and then reboot again as a loop.
My X8 phone is E15i, running CM7.1, with FXP 43 kernel.
I tested some features are working, like 3G, dial calls, speaker music, multi-touch (dual-touch?). I can even install apps from market via 3G.
So, I uses CWM to do "wipe data/factory reset". The phone can load up successfully again.
Does anyone know what's going on? Any solution?
Thank you very much!
No reply? oh, did I post in a wrong location?
Confused
DOnt know!
oh it's confusing? oh sorry
Basically, My X8 phone reboots immediately after I turned on wifi.
and it's running CyanogenMod 7.1 (Android ver 2.3.7), with FXP 43 kernel.
I am having the same problem
I am having the exact same problem on my LG G2x Domination build 79 as well.
Every time I turn my WiFi on, phone restarts it self
I tried pulling out the battery but that didn't fix it.
if anyone have any tips please help us out
Thank you
Yea, Wifi is still not working up to now :S
Any guess or any related hint I can refer to as well?
Now I mostly just use bluetooth to transfer apps XD
Well , did you try flashing another ROM ?
The ROM and kernel are very old with many bugs, the development of them stopped a long time ago. Flash this kernel and this ROM.
I am facing the same issue.
After installing the latest MiniCM and nAa Kernel, my phone started rebooting constantly -when enabling the wi-fi or Data. .
I have noticed that it works only on charger. I decided to re-flash to stock 2.1 but it did not help.
I also flashed Android 1.6 stock on the phone but it did not help.
It is like it has no battery power.... What can I do?
I
Okay all!
I had that prob when my phone on old kernel and ROM
Root n unlock BL
Flash the latest kernel
Backup!
Factory reset, etc
Flash ROM
Done!
Do not restore data in diferent kernel!
It make some error like wifi bug!

Ow yeah..

If still not working use my instruction..
Sent from my E15i using xda app-developers app
I did it with no success. Any other ideas?
Tried to use the stock kernel,nAa 13 With MiniCM (latest version) I am getting worried. What could have happened? The phone is working only on charger without reboot.
I even tried afls9 kernel+GDXv28b.
The steps i have performed:
1) Wipe data/factory reset
2) Wipe cache partition
3) Advanced - wipe dalvik cache
4) Wipe battery stats.
5) Flash rom + addons
Nothing happens. As soon as the USB is disconnected from the PC or Charger it starts constant reboot...... :crying:

[Q] HELP! i think i bricked my 5830D!

So I, (like apparently many other 5830D users) was having the bug where it would randomly restart for no apparent reason.
i read that froyo did not have this issue, and figured id give it a shot. i downloaded the ZSKC2 2.2.1 files and loaded them into odin with cooper_v1.0.ops, connected my phone and hit start.
it said it installed everything just fine, but when my phone went to reboot, it didnt.
it flashed a black, blank screen for maybe a second and that was it.
so i tried to go back into download mode on it so i could reinstall the firmware it had before, and i couldnt get it to work.
it would turn on the screen, flash the "downloading..." text for a second, and then turn off the screen. it was weird, because the text was white, not the yellow it always seemed to be. odin recognized my phone for that second, but that was it. once the display turned off, the connection went away. i've tried other usb ports, but no luck
is there any way i can fix this? or is my ace bricked for good? i have no warranty with it because i bought it used.
ive read about a USB jig, will that help?
please, any help at all would mean a lot!
1) You should have taken the bill & the warranty card from the owner you bought this phone.
Coming to the point, it appears to me that there might be a problem with your battery, but I ain't sure about this. Try using a different battery with your phone. Also, are you sure to have used the odin & stock rom for S5830D & not S5830 ? Check these aspects first. If you've got them right, then there'll be either a multi-package or a single package filed stock rom for your device. You can google for the exact odin flashing, try again to boot into download mode again & flash. If your phone fails again to go into the download mode, use the search option here on xda to find out the issue with your phone or the best thing to do would be go to the service centre & tell them that donno what went wrong & this happened.

okay, i tried the battery from my other phone and got it into download mode, i installed the stock rom and it is working again, but the reboot problem is still there!
is there any way to fix that? i have a feeling it might have something to do with the kernel, other roms still reboot and apparently froyo doesnt, the only thing common between all the gingerbread roms that i can think of is the kernel.
i have flashed S5830,T,L,B roms with no issues, but the reboot still occurs. cyanogen hasnt helped either, do you have any clues?

After flashing via odin, if you face a bootloop, reboot into stock recovery & do a factory reset & reboot now. It should work.

..but it is not tuck in a boot loop. its doing what the stock roms did; it'll boot into the rom fine, and you can use it, but once it goes to sleep the phone restarts itself.

If you are having this issue with the froyo, try it out with GB. If the issue prevails, go to service centre. Sorry for repeating the same thing again & again but that's the best I could say of it...

[Q] Wifi problem

Hello everyone! The wifi of my G.Note turns off at any time. Even while I am using the phone!
This problem first occurred on an ICS rom but it wasn't on a daily basis. Each time I had to modify the "wpa_supplicant.conf" file by deleting a few lines (some networks) using the text editor and then right afterwards I could turn it on.
A few days ago the problem occurred a few times a day and it didn't turn on right after editing the aforementioned file.
Then I flashed a JB rom and it seemed OK the first day but then again the same problem appeared.
Is there anything anyone can think of?
Maybe wifi is dead for ever?
so whats the issue now? no wifi or disconnecting?

Now I cant't turn it on at all.

If you mean wipe data/factory reset /cache partition /dalvik, I have done all that.
Ok.. what kernel are you on now? Install Philz kernel and go to Philz settings and choose "clean before new rom install". once done.. choose advanced and reboot download. flash the rom again. let it boot and check.

I think wifi is dead...
Yesterday I flashed a stock GB rom and wifi was working fine. I have flashed many roms but it was the first time to flash one with pc odin.
Before flashing I wiped data/factory reset, cache partition, dalvik cache, format system / data / preload.
After that I downloaded a new stock JB rom and flashed it with pc odin again. All the afternoon everything was working nicely and smoothly.
This morning again wifi started disconnecting...
What I have to point out is that the problem occured when I connected to a few different wifi networks.
The phone after all these wipes and formats it keeps the wifi data. I connected to wifi networks without asking for a password.
I think I need to erase everything but I don't know how to do that. I want to make the phone exactly as it was when I bought it. I am not saying this will fix the problem but I don't know what else to do.
So you mean to say even after formatting system and data, the wifi connects auto?
When you install a new rom, the phone takes you through a setup procedure where you need to provide the wifi details and a Google account. Does that not happen in your case?

No, it does. It takes me through the setup procedure where I provide the wifi details and a Google account.
But after setting up the phone, when I switch on wifi it connects to some old wifi networks automatically. Though some of the old networks require password.
Is there any way to restore phone to factory settings?
I mean to delete everything... pics, videos etc.
thats because the google account automatically syncs these to the phone.. other data on usb storage can be deleted by mounting it on the pc and formatting it.
My school's wifi signal very strong, 64MBs, but i can't connect, it always "Obtaining IP Address", loop.
Install wifi analyzer from the playstore and check other wifi signals, just to check your phone wifi. Can you try other wifi networks ?

Phone turns off at any time and when power button is pressed it won't turn on.
Only when I pull out the battery or when I enter recovery and choose reboot system it will turn back on.
I just flashed a stock GB rom and everything is fine at the moment. I will leave it as it is to see how it will go...
I can't figure out what is wrong.

Can't get into recovery?

So After Installing Revolt Rom for awhile. I noticed I can never see the sony Logo and can never get into the cwn recovery mode. So I decided to Flash cwn again but now I'm stuck on cwn with no way of getting into adb mode no more as The device can't be seen. What am I doing wrong as I can't use my phone no more -.-. Hope for some help as this is doing my head in. Also my vibration is faulty as it stopped working for awhile also.
If I was you just reload stock ftf and exclude data wipe in flashtool

Problem is I can't access my phone as it stuck on the cf load with the 10 second restart. I can't even go back on bootloader mode some reason.
You phone won't even reboot when holding down power and volume up button for 30 seconds and you should hard reboot
Is you phone locked or unlocked bootloader
Sent from my C6603 using xda premium
Yeah I did a hard reboot for 30 seconds and still does the same.
My phone is unlocked bootloader.
So are you stuck in cwm and can't get out, holding the power and vol up should reboot you phone
Edit: did your phone reboot
Sent from my C6603 using xda premium
Yeah I have with hard reboot or even rebooting. Still stuck on cwn . It was smooth last time. Been looking around for a solution and noting yet -.-
If your phone does reboot then you can reload ftf with flashtool thought flashmode
Plug phone into computer and get flashtool prepaired with stock and then when it says put phone in flashmode hold power and vol up for 10 seconds release and then move your fingure so it holds down volume down this will put your phone into flashmode when phone reboots and flash tools will reload stock
TICK EXCLUDE DATA otherwise you will loose you data

Ok thanks I'll see I can do this once I work on it tonight thanks!
Well I've retool and did what you've told me. Now I'm stuck on boot sync where the rainbow waves keep showing non stop only.
Is it wise to flash the 253 ftf though?

What you can now do is flash dooms v9 via fastboot and then load up cwm and install custom rom, the new .244 roms are not compatible with v9 just to keep that in mind

Guess I better not flash dooms v9 then as it's not compatible as you said.
Does this mean I should Flash the outdated version and just get it working with v9? As there isn't other solution?

[Q] CM 10.2 Team Canjica - WiFi Lan Problem

Hi guys
At first, thanks for the ROM, is really good, saved my phone from the old stock updated Samsung ROM.
But the WIFI doesn't connect whit nothing - I'm not talking about WIFI DIRECT, but WIFI LAN and INTERNET -. It appears that the phone is connecting whit the router, but after a second it stop trying to connect, and shows me that the lan is "Saved, secure by WPA/WPA2". It's work whit all the WIFI LANS i had tried to connect. May be something in the RADIO setings?
PS¹.: The Google Play doesn't connect too, even in a good sinal of 3G.
PS².: Sorry if someonse have already talked about this problem in this forum.
PS³.: I am brazilian, so, this phone is the brazilian model (4GB Memory), and I live in Brazil (if it's important for the network settings).
Did you try it to restart your modem?
Sure, several times.
I had tried too reinstall the ROM, several times.
I had intalled the Omni 4.4 ROM too, but doesn't work, the same problem. But in this last, the Google Play had worked.
Edit¹: I tryed to connect in diferents WiFi Lans: protected, open, Hot-spot.
Edit²: Updating: I install CM 11 Maclaw Rom, and the same happens: no conection whit the Google Play, and no connection whit any WiFi Lan.
does wifi connect with stock ROM?

CM all roms r buggy sheet -_- use harshjelly stable rom or slimbean :good:
it happends sometimes.
usually simple phone reboot or enable / disable ariplane mode helps
sometimes after reboot you are stuck with "enabling wifi" ... that actually never enables it
in such case I enable ariplane mode, remove enable wifi widget from home screen, reboot phone while still in airplane mode.
when phone boots it will not ask for pin to sim card as it is still in airplane mode.
disable airplane mode
enter pin to get into sim card
enable wifi manually
it works from now on (untill gets bugged again ) same procedure to fix it.
I also have this enabling Wifi problem sometimes with the new 01.04.14 CM 10.2 Build. Is this Bug new or did it also happen on older builds? On Stock Rom I have no problem.
I can fix it like th3cr0w explained. Sometimes waiting one or two minutes solves the problem, too.
