Hi,
I am new here, and this is my First post,
I am running stock ROM 4.03 (I9100MUGLD3_I9100MBMCLD3_BMC), I did a "wipe data/factory reset" and then update the new ROM 4.12(I9100MUGMA5_I9100MOYCMA5_BMC) by Odin 3.04.
In this case, my phone should be wipe and has a new fresh look and my setting should be all gone. but I found out my WiFi connection for work still list inside my phone, and when I back to work, the WiFi connected automatically.
so, I tried again, wipe data/factory reset, flash it back to above Original Bell ROM 4.03 (I9100MUGLD3_I9100MBMCLD3_BMC), when I back to setting, my company SSID still in the phone. so I root the phone and wipe data/reset, then flash it to (SuperNexus-2.0-i9100-BUILD1) by using the MicroSD Card. my company SSID is gone, so I did a wipe data/reset, then flash it back to 4.12(I9100MUGMA5_I9100MOYCMA5_BMC) by Odin 3.04. again, my company SSID come back in my wifi list. and when i back to work, wifi connect again.
is there something I didn't do it in the right way to flash a new ROM?
or how do I completely erase EVERYTHING in my phone, in case I give my phone to someone else?
also, after I flash to different ROM's(GalaxyMOD_XWLPX_v3.01_by_AJ, BestS2ROM v1.1, Galaxy S2 I9100XWLS8 (4.1.2) - Spain, I9100XWLSD_I9100OXXLS6_I9100XXLS8_NEE), the serial number of my phone became PPPPP, but when I flash it back to Stock ROM, my serial number back to normal. does anybody else have the same issue?
Thats because you log in with your google account and selected the option to restore a backup from your google account. Wifi passwords are saved into you google account (if you select that option).
Don't double post god damn it!

I'm having a problem since I flashed the sensation rom (by crysis21) on my SGS2 yesterday.
My internet connection (mobile network) doesn't work anymore
I checked the APN settings and already resetted them and enterd my APN settings again. But it still doesn't work. I also restarted the phone multiple times.
Does anybody know where the problem is?
Installation steps were:
*copying the rom to sd
*CF-rooting the kernel via Odin
*booted up in CWM recovery and chose "install from zip file" and installed the rom (without any wipes)
Before I had the default samsung factory rom on it.
Have I made a mistake?

Have you checked the APN settings are the good ones? One thing is to have ones enabled and other totally different is to have ones that actually work.
Also when you go from Stock to Custom ROM you should do a full wipe!
Go to CWM and format /system, /data, /cache and reinstall the ROM.

thanks, I'll check this out as soon as I get home.
I refrain a little from doing a full wipe because I don't want to get all my apps deleted (and I'm a little too lazy to perform a backup). Would mybe a new modem solve this problem?
And of course I checked the APN settings. I deleted the existant APN setting and added a new one so the settings can't be the problem.
I also checked some entries in Settings/Phone Info/Status.
It says here (translated from german):
Mobile Network Type: HSDPA
Service State: Function (or working rather)
Mobile Network Status: Disconnected (but sometimes it says also connecting here, though it never really gets conencted)

Even though I wiped everything, the data connection still doesn't work.
I did
"Wipe data/factory reset"
"Wipe cache partition"
"Wipe Dalvik cache"
and after that I installed the Sensation rom zip file again.
The data connection still doesn't work :'( (I added the APN after install, of course - the settings are 100% correct).
I also installed another rom (infected rom) but there's still no data connection.
Am I missing something? I'm getting really desperate over here.

You could try flashing another Stock ROM via Odin and see if in stock works or not, then try a Custom ROM.
Sometimes the phone takes a while once you flash a new ROM till it establishes a decent 3G connection. Having "Data enabled", how much did you wait for the phone to establish a connection?

I thought so too... Well, at work I waited some hours for the data connection being established but nothing happened.
This is crazy. I even restored my system with CWM and it still ain't working.
As soon as my GF comes home I'll replace the sim cards. Maybe the problems at the providers side...
after that, I'll try a stock rom (via odin).
thanks for your tip

I have the same problem and I'm on check rom.
i'm having the exact same problem, but with multiple roms and not just one. i tried omega and delv. both of these are giving me no data connection (only at the beginning) but once i restart there's no data connection.
did you manage to figure out what went wrong? I've resulted in my original rom that i had by restoring it using cwm.
dear sir,
my device is micromax canvas a1 aq4501. when I recovering a custom rom like cm13 my device Internet data not connected. I fully checked setting like mobile data, apn, but it still not working.
now I want my device situable custom rom. please give me the right information.

Hi all,
I've flashed quite a few times before I settled with my current Insanity rom. But then I decided to try out some new ones since I have time during the holidays.
I tried flashing Omega and Delv with cwm (Whatever version they currently have now), both at the startup didn't allow me to bypass by pressing the 4 corners. i thought nothing of it and just continued on and restored my stuff using titanium backup. before my sms, gmail accounts and call logs will get restored but it didn't for both. so i decided to restart my phone to see if it'll come up. it did not. in fact, the data connection goes missing. (i did get data connection when i first loaded up the phone right after the flash using cwm) i only have full bar of signal, but no data.
I thought it was just a rom thing or a bad download, that's why I tried flashing another rom, but once I restart my phone, the data connection goes.
I got so frustrated that I just restored my old (current) rom from cwm.
If anyone can help me on finding out what may be the problem, that'll be great. I really do want to start flashing different roms again because I'm getting bored with my current one.
thanks in advance!

I'm sorry my English award is not very good I am a Chinese.
can you make sure that you have wipe your phone 2 times?
wipe data factory reset and wipe cache partition? before you flash a new rom?
and the problem may be your kernel don't work well . you can flash another new kernel or flash a new cwm
wipe your phone is very important
if these mind can not make your data well you should flash your phone
by odin . use this software to make your phone well
thank you for your reply.
I have wiped my phone very thoroughly: wipe cache, factory reset and even dalvik.
aren't the kernels automatically installed when i install through CWM?
i'm not too sure about this kernel thing as the many times I flashed before, I never had to install kernels on its own through odin. i just flash the zip file of the rom through CWM and it's all good.
so you're saying i should use odin to flash instead of cwm? is there a major difference? i'm much more comfortable with cwm though.
Try flashing a new modem .
Check IMEI is correct .

Have you set your APN settings correctly according to your phone carrier's settings?
Also try your carrier's CSC on your phone.
Set your APN manually, I had this before as well...
Other options is to get the Tweaker App from the Market and when connected via Wifi then it sets your APN as well.

Thanks for the suggestions.
The APN one sounds easier to do. That option's under wireless and networks correct?
Currently, I only have one selected. I'll check it out when I flash the new rom.
What's this csc though??

So I was running a Shomans rom really liked it but decided I wanted to run 2.3.6 again rooted so I reverted back to stock build and now my modem dont seem to be working anymore it picks up signal then right back out my wifi works fine but cant make any calls or anything. Ive cleared data/factory reset even ran with a unrooted build but same issue.
Check your apn settings
Depends on a lot. Apn settings. The modem ur using. Did u do a full wipe between builds. (No this is not factory reset. A full wipe includes wiping /system /data /cache /dalvik partitions.) What apps do u have installed? Anything to turn on/off data like a power saving app?
Sent from my SGH-I777 using Tapatalk 2
full wipe, no miss
Ok, Sorry for the delay in response. So what it looks like is my modem it will have no service turning on then goes in and out and just drops it for a while. I starts working randomly. Like from Edge to 3G nework change I lose service. I went from ShoMans build to the stock build. I didnt wipe everything just factory reset. As Im a noob and just starting to get into all of this I dont really know how to do that step.
Just a interesting observation. I took my sim out and sd card restarted my phone and instantly had signal. Emergency calls only but it had service from the start as mine goes in and out for 5-10 mins before having and maintaining a signal. Wierd.
Well Ive fix the issue it wasnt a full wipe that solved it. The Build I used to go back to stock something was wrong with it. I grabbed the build from Entrophys back to stock. It was creepyncrawly's post that took it back to a stock build and able to fix the modem from going in and out. Thanks Creepy!
The one that didn't work was probably a bad download, or a bad flash.
Hi guys,
I wonder if someone can help me with this... really annoying problem!
I was checking out various roms i downloaded here, started with 4.0 aokp which was great, then gave cyanogen 4.2 a try, but then i wanted to go back to Aokp 4.0 cause it seemed to run faster
Now first thing, i couldnt get rid of cyanogen (no offense intended) cause when i wiped all data, cache and dalvik it just took aokp a few seconds to install from CWM recov, that doesnt seem right, right?
Then installed GAPPS, but still it ran on Cyanogen
So, i did a NANDROID backup, which made my phone like before i started with all this..
THIS IS WHERE IT WENT WRONG?
now it just wont read my simcard
i tried my sim in my old phone and that works fine, so the problem is in my phone somehow
is it something about the radio settings specific to my phone and network?
how can i change these settings and are they specific for my provider?
you guys always helped me out so i hope you know what i mean..

I've exactly the same problem.
Are your wifi and BT still OK ?
Is your IMEI (*#06#) still the same as under the battery ?
Was your phone locked ? Did you buy it with a SIM ?
My problem appeared after flashing several different modems/RILS : I got no error warning anywhere, but after reboot, I completely lost my netwerk connection. (no voice calls , no mobile data)
At first I thought a bad RIL driver, so I restored my Nandroid backup from the day before (after wipe cache/wipe dalvik/format system), but still no connection with the netwerk. and can't even make voice calls.
Then I was in panic !
After this I did a complete factory reset, and wiped/formatted cache/dalvik/system/data/SD-card and went in to download mode. After loading a stock ELLA for my region using Odin, still no connection. I was also never asked to enter the PIN-code for my SIM to unlock it.
Damned, this is an embarrassing situation : I can't think of loosing my SG3 for several weeks if I have to send it to Samsung !!
Mu phone is bought without SIM, so it's not SIM-locked.
My Wifi and BT are still OK, my IMEI is also still OK.
Any other ideas, please ?
How do I come in the service mode for the Radio ?
This is the way my netwerk is indicated : a circle with a stripe, much like the famous traffic sign.
Its fixed
So i have no idea how it eventually got fixed but if someone else has this problem, heres what i did:
Full wipe/factory reset blablabla all that
Did Nandroid restore again, put the AOKP ROM and GAPPS back on my phone
Installed ROM which was I9300CEDLI1
Used Odin to install latest CWM, which was already on there, but still
Then booted into CWM and installed .zip of course
This still went suspiciously fast since the very first time it took way longer, that worried me but,
Installed GAPPS again,
Rebooted... IT ASKED FOR MY PIN NUMBER!! hell yes that was what i wanted!
So now it again sees my simcard in there, so now i can make calls end use intnet again!
Still i think it started after the nandroid backup for some reason, or it may have been because of wiping Dalvik Cache?
I have no idea if that even makes sense

Good to hear your problem is fixed !
I'm still not able to make voice calls or enable mobile data : "insert SIM card" is the message I get.
I did already twice a full reset/factory restore and flash a stock ROM using PC Odin, but no avail.
Today I did a restore from my EFS folder using a backup that a had made before the problem appeared, but no avail.
BTW, did you also have the same indication from network status as on my screen-shot ?
Any idea what else I can try ?
I'm getting desperate .....
I'm having the same trouble after doing backup in TWRP when boot up it doesn't recognize the sim card.
I've flash CM10.1 and it only work after i remove the card e put it back on.
Try to see if it something about the simcard.

Hey guys
I need some guru help here :/
I've flashed cyanogenmod 13 with android 6.0.1 on my i9300 along with some gapps (stock version). Everything works well, besides the cell reception.
I've been able to see other networks around but couldn't connect to neither of them. (i'm on roaming, in germany, while my sim card and the phone are from poland)
I have applied no signal fix from here which didn't change anything.
Then I've flashed this (the one with "Poland" next to it), but that only made things worse, as the whole "cellular network" menu in settings is greyed out.
What I've figured out is that when typing *#06# the phone app makes some noise and hangs, and in the settings there is no IMEI number.
This leads me to the conclusion that EFS (seems empty in the TWRP file browser) is broken/cleared.
I've seen many instructions on bringing it back to life, non of them are clear to me, and all use Windows. Is there a way to do that on Mac OS, or.. basically is it THE way to go for?
I would appreciate all the help as I need that phone in the next days :/ thanks!
@krecio4:
1. Look for efs-backup. Some kernels create this. Or as part of TWRP-backup. Restore it.
2. Flash latest firmware with Odin. If IMEI is still gone afterwards, try KIES repair function.
3. Let it repair in service center.

thanks a lot @rp158!
I've tried searching for an efs backup but no luck :/ any idea where do they create it? restore option only has those files that I've backed up.
latest firmware you mean the official one, right? Is there a way to do it on mac os?
cheers
@krecio4: TWRP backup contains efs-partition, if you chose/ticked it. Kernels (Boeffla, Agni) store it in sdcard0, but if you never flashed a special kernel, it's over.
Firmware means Samsung's stock 4.3 from sammobile.com. Look there, if they offer Odin and KIES for Mac. Otherwise lean a Windows pc. It's useless to make it more complicated by struggling software.
@krecio4: read this. That's not the solution, but if that all caused by actual CM13-nightly, there comes perhaps any...
I have the same problem with latest nightly. This work fine: "cm-13.0-20160523-NIGHTLY-i9300.zip".
@krecio4 I think that you have to first flash latest firmware then root your phone and then you have to use z3x box, hope it will fix :good:
thanks for your sugestions guys
What I did is to get the latest firmware from sammobile, restored it with Odin, phone was working, I was receiving calls and texts.
So I installed TWRP, backed up EFS, System, Data, and one more thing that was marked.
Then i did a factory reset and installed latest CM13 + gapps in one run (as a batch of files, selected the CM13 first, than the gapps in the que)
rebooted
Again - CM13 works well, but it says "please insert SIM card" :/
No IMEI, IMEI SV (Unknown)
Cellular networks in settings are off, and greyed out inside, "preferred network type" is "Invalid Network Mode (-1). Ignore"
Do you think there is any hope?
I noticed that EFS is empty, after restoring it from backup, and rebooting, it's empty again.
so tired of everything, I went back to the original software using this method (even easier than Odin) http://forum.xda-developers.com/galaxy-s3/general/how-to-factory-installed-firmware-sgs3-t1838480
If you come up with some solution, I'd love to try Cynanogenmod for longer and.. for real
1. Be happy, that your efs-data are ok. Make in TWRP a backup of this partition only, for worst cases.
2. Try @mexit's advice.
Can I with no problem have a custom recovery installed while using original firmware?
So you are saying that it might be with the last 3 nightlies that they are messing up with backed up EFS? If so, I'll try installing the one you've mentioned, but now I've list 2-3 days for the whole crap so I will wait until I have too much time But thank you very much for your support!

ok, as I don't give up easily, as you can see, I did another approach. Backup, backp EFS only.
Installed the edition from 23rd of mai. All good! But during the "installing apps" during the initial boot, close to the end, the battery died (after the screen flickering). but reboot and it all seems to work well Any issues that could appear after an unexpected reboot during the first boot? Do you suggest to do factory reset and flash CM13 + gapps again?
If I understand well, battery died during compiling Dalvik/ART. Should be happen again after cleaning both caches. But to avoid any mess, I would clean flash the ROM again.
So you suggest to do the factory reset, install CM13, install gapps, reboot ?
No.
Wipe system, data, cache, Dalvik cache.
Flash CM13. Wipe cache, Dalvik cache.
and gapps installation shouold be along the CM13 in a que right?
@krecio4: flash GApps afterwards. Read the last posts of CM-thread: your problem was probably caused by a modem-bug in CM, should be gone now.
after the wipe cache & Dalvik?
so CM13, wipe, gapps, reboot?
Ok, very precisely:
flash cm13, wipe 2 cashes, reboot
if net and wifi ok, make a backup of this state
flash GApps, wipe 2 cashes, reboot
case closed
