No network after installing CM7.1

HI ALL, Im pretty new here. after so many tries finally i was able to install cm7.1 on my defy. but im facing some issues. before the installation i forgot to take a back up of the existing ROM so if i have to go back to the previous ROM how to do that? and also there is no network coverage after the installation. please please anybody help!!!!!!

Have a vibrant myself but I'm helping a buddy get cm7 on his defy and after flashing didn't have a network signal. I looked at the cm7 install guide and it referenced a defy base band switcher app for better coverage. Had him try that and he got his data connection back. Might want to look into it or read the guide.

If your previous ROM was stock that came with your phone, flash the corresponding SBF file from the sticky on the Dev section to go back to stock. If it was some other custom ROM, wipe data/factory reset in CWM and flash the old ROM. Make backup of your apps using Titanium Backup if you want.
For CM7 network issues, choose the correct baseband from Defy Baseband Switcher. For India, pick anything that is 900/2100MHz...
Also, make sure you have read as many guides and First Posts on important threads as you can. Here is a collection of good threads you can read for these questions, and more that you might get later:

Hello! Noob here as well.
I installed CM7.1 stable on my Defy (running 2.2.2 foryo) 2 days ago.
All went well, except that network connection is lost after a couple of minutes after boot. Sometimes it takes an hour or two but I still end up with no connection.
I've googled everything about it in the last days. I played with the Baseband Switcher and although most options in the BB Switcher work right after a reboot, it still looses the signal after a couple of minutes.
One thing I noticed, when the signal is lost, trying to set the "Airplane mode" will fail. If trying to set Airplane ON - the notification icon will not replace the signal icon and will also be unable to set Airplane OFF (since it didn't finish turning ON).
I also noticed that if I force stop the "Dialer" system app, then the Airplane notification ico shows up, but still there's no way to turn it OFF (it's disabled in the menu). After a reboot Airplane can be set OFF and everything works for another small period of time (..until baseband crashes again?).
Hope it makes some sense. I'm quite sure this is not an operator issue or hardware related, since my Defy worked just fine before CM7.1
Also, I am located in Romania, operator is Orange.

I have the same issue, except that it is much rarer (ranging from every other day, to even a month between such incidents). It can also be triggered sometimes when I turn off Wi-Fi and the device tries to regain mobile data connection (not sure if it matters, but I set the network mode to 2G on my phone). The battery drain is increased if this occurs without the user noticing - the phone seems to search in vain for the signal.
Using the latest SEA baseband on M1 (Singapore).

I get this problem too. Happens every so often when I'm at work. I've always put it down to a bad signal where I work but as I always turn the wifi of before leaving home it could be down to that. If anyone has any solutions it would be great

Ok, a little update on this:
At the office now, further playing with the Baseband Switcher, I ended up selecting "Italia RT 2.51.1" which has the same 900/2100 freq that my operator requires and it seems to work. Even getting 3G.
If "2.51.1" is some sort of protocol version, then all the other options I've tried were either 4.x or 3.x or even 2.21.x ..and none of them worked for more then 30 minutes.
Also, not sure if signal strength has something to do with this because I did a test, going to the basement of my office in order to loose signal, then back up and it worked - got the signal back, without reboot or anything.
Also, I would really appreciate if someone could explain in a few words what those version numbers mean (ex: "Italia RT 2.51.1"), as I know nothing about gsm bands and protocols.
UPDATE: Back home, lost signal again, after a whole day without any problems. Funny.
UPDATE 2:
So after much google searching and trying literally every option in the Baseband Switcher, I switched my SIM card with a friend's SIM and guess what.. IT WORKED! Even more, when I inserted my original SIM into the other phone after a few minutes it lost signal, too! It was a faulty SIM, that has just started to "die".
Conclusion:
- Keep playing with that Baseband Switcher until you get something that works for you.
-Make sure your SIM is working properly in other phones, otherwise ask your operator to replace it.
Thanks and hope this helps.

ZeDevil did you try using other Basebands to see if you get better battery life ?

Not really. As long as you have a working Baseband selected (with correct frequencies) I don't think it matters.
But overall CM7.1 has better battery efficiency then stock ROMs, or at least that's what I felt.

update:
Well, I had a play with the baseband switcher, realising i was on 'international'. I switched to uk t-mobile and from there it seemed to work much better. A slight blip at work today (think it's a bit of a signal black-spot though) but restarted and it seems fine again. I've also just realised it's gone 37hrs since its last charge too
Strangely my other problem, the backlighting on the soft-keys not working, fixed itself at the same time. dunno if these two things are linked or not?

i use the CEE one.

[Q] Moto Defy voice call/data usage freeze problem

hiya...
i'm posting this thread because i've been struggling to get some help with this issue. i.ve googled for any fix but didnot find one...
motodefy on CM7
just unlocked my motodefy which was locked on orange before(unlockcode used),
i am now using a 3uk sim... 3uk settings is there in the APN
problems:
1.hangs when i am in the middle of a call ( cant here anything/cant do any call/ and cant receive any call) handset does not hang coz am able to move between menus, open and use apps)
2.after it hangs i cannot use data I.e download, google store coz that one freeze as well.
3. sometimes when its hangs, i cannot end the call (like if the dialer hangs is frozen, i press the end call button, it says hanging and it stays like that, but sometime it hangs the call !
4. the signal icon and the 3g/H icon is on the status bar, but they dont react.
5. i reboot everytime i have this issue... someime comes back online very nicely( with signal/3G/H icon showing on the statusbar) and some time it doesnt (meaning the signal is there but not the 3G/H) ... when it does come back online nicely ... i start to use some data... example i am using google play, it will let me download some apps .. but eventually it will stop working in the next 5 mins ??? and after this again i will not b able to call blablabla ... same stuff as above ...
ANYONE, OTHER THAN ME EVER HAD THIS WEIRD ISSUE WITH THEIR DEFY BEFORE ??

Try wiping all data/cache in recovery
hi,
why dont you try wiping away all you data from the recovery mode and then reboot it once again.
Thanks

oh.. u know i like changing/trying roms ...eventually at first when i had this issue i did a factory reset/wipe from the recovery and installed the cm7 again but its a persisting issue ... i just took to 3uk shop .. they told me they cant do anything coz its not a 3 handset their customer service was not able to help me either ... i am really really desperate to get it fixed ....

No problem if i use an orange sim
i would like to point out that i do not have any problem when i am using an orange sim in my defy ... callss/txt .. unfortunately no credit to try data but i can surf a bit of orange pages without any trouble ... why is it like that with 3uk

I don't know the reason, but sometimes I had this type of problem with my Defy (green lenses) and CM7. After a hardware issue I take it to the service and they replace the whole main body. So now it has red lenses and I switch to a CM9 nightly ROM (CM9-NIGHTLY-120613-Defy+ from Eclypse3). Don't know why, but my problems with the calls hangups and connectivity solved.

Thank you for your help everyone ....although i am in uk am able to use the Vecton sim with USA baseband its on trial for the moment .. we'll see if theres a glitch i'll keep updating

Questions go in the Q&A section

Issues sorted..
Ragarding to my post above ... i managed to work aroung this issue ....
just have to set scaling to Conservative and enebling all modules in cpu settings in revovery...
Can be closed now Thanks

Signal "unknow" on my N4, Help

Hi, im having some issues with my signal on my N4...it randomly started a few days ago. This is what it happens:
While my N4 shows to be conected to my 2G / 3G network, sometimes (very frequent now) it totally drops the conection, the signal triangle seems empty, and going into airplane mode and coming back wont fix it, and when i log into the *#*#4636#*#* menu, it shows "Unknow" on a few options even on the preferred conection type, and i cannot choose any option there because it will go back into Unknow. The only solution is rebooting my N4, but this is just a temp solution because the problem shows up again not too long after its ON.
I have seen that if im constantly sending and recieving data, it keeps it conected longer, like when streaming a video. This problem started to occur while i was in baseband .48 with stock 4.2.2 rooted/unlocked. I did a complete wipe, and reinstalled 4.2.2 stock, but this time with .54 baseband, and the problem persist.
its been hard for me to find old posts about this problem in particular, seen other people posting about alike problems, even losing the imei number, but that doesnt happens to me, i still can see my imei number on *#*#4636#*#* even when everything else there shows unknow. I will attach an screenshot, its not in english, but i think you guys can get the idea.
details: My N4 didnt drop or anything, i already tried removing the simcard to check it, so i have no idea what to do now. I appreciate any help

Maybe your SIM card is bad or not seated properly.

Its well seated, and yes, a bad simcard is another option, but i wont be able to check that till tomorrow i guess, but just wanted to make sure this doesnt seems hardware/software side

[Q] S4 - disconnecting from network and not reconnecting again

Hi all,
Regular reader but hardly ever post!
I have a Galaxy S4 (GT-I9505) - with Android 4.4.2. Unrooted.
Purchased and used in Singapore on the Starhub network since around October 2013. Everything was working fine until approx Feb or March when the latest Android version, 4.4.2 got rolled out.
Ever since then I am experiencing regular disconnections from the network. But the phone does not re-connect back to the network again, the only fix is to restart the phone.
These disconnections are often once or twice a day, and are very frustrating because if I don't notice it, I may be off the network for hours before noticing it - and are therefore missing out on calls emails etc etc.
This only happened after the Android 4.4.2 got rolled out, so I am pretty confident this is the cause of the problem.
What I tried myself to fix:
- restore APN's back to default state
- Factory reset (both via settings, and via boot screen)
What I have been able to narrow down troubleshooting, is:
- Disconnects seem to only happen when Network Mode is "LTE/WCDMA/GSM (auto connect)"
- If I use network mode "WCDMA/GSM (auto connect)" the disconnections have not happened (yet!)
- When the disconnection does happen in the first mode, I cannot manually change the network mode. The radio buttons are greyed out, and if I try to select "WCDMA/GSM auto connect" the request times out (I forget the exact message - it does respond to the tap but then nothing happens)
So it seems to me this is some sort of software bug/fault introduced with Android 4.4.2 that affects 4G connections.
After that, I have taken it to Samsung for warranty service. I have now had 4 visits to them and they have not been able to fix it yet. This is what they have done so far:
- First visit - factory reset (despite telling them I already did that) - did not fix
- Second visit - checked hardware and replaced mainboard. Did not fix.
- Third visit - checked hardware again and factory reset again. Did not fix.
- Fourth visit - who knows. I think same as visit three but done via a Service Manager instead of staff, Did not fix.
When I first called them back in Feb or March, they said it was a "known Issue' and sugegsted to "wait for a patch". However since visiting them, they said the known issue was only with Note 3's (not with S4's) and replacing the mainboard on the Note 3's fixed the problem. In my case replacing the mainboard - twice - has not fixed it.
I'm getting very annoyed with Samsung who seem to just be trying the same thing each time and are not fixing it. Staying in 3G only mode is a workaround but not an acceptable solution.
Now they've asked me to take if back again - for a 5th time.
Beginning to wish I had never bought the S4, or at least never got Android 4.4.2.
So I thought I would turn to here for help instead, I think you guys and gals probably know more than the Samsung service staff!
Any suggestions?
By the way, I don't run any memory/battery saver apps. I do run one data usage monitoring app that I thought perhaps was conflicting, so I tried not installing it after one of the resets, but the problem continued.

you CAN try other modem flash, but be careful with your warranty.
I do not know about the warranty conditions in your country, but in EU normally 3 unsuccessful repairs = phone refund or replacement.

I would try reflashing stock file or just flash a different modem

Hello, just like you i have been reading the post but never posting because i just came here to learn, nothing to share from this side...sorry.
But i am having the same problem as you. I bought my phone in Switzerland on march 2013 but i live in Uruguay. I was just thrilled with my s4 until the 4.4.2 update came out. My connection keeps on crashing and it doesnt matter if its on 4g or 3g just make me miserable all day. Only the two of us is having this type of problem??
I believe is some kind of issue with the new bootloader i just updated with a patched rom that came for Germany last week (the one with kids mode) the phone work fine for a hours and then crashes, so this update didnt work. I have also flashed very differents official roms and modems but nothin seem to affect the problem.
I have another problem even though my s4 is 4g i cant connect to 4g network, every configuration is fine i just cant connect, any thougths??
Thank you very much.
Sorry for my english.

I should add, I took it in *again* to Samsung, to the Service Manager. Said they would replace the antenna and try that, which they did.
Still have the same problem though.
Not sure who to believe, Samsung are starting to run out of ideas and starting to say it may be a network issue. But if the network is down, then the phone should automatically reconnect once the network is back available again. And it doesn't.
I'm convinced it's a bug introduced with KitKat, as the problem only started then, but of course I cannot prove it...

Sounds very similar to my problem, that it just started with Kitkat only. I'm sure it can't be just us two having this problem! I don't have anything special or different installed on my phone, and it's too suspicious that it was working fine, 100% perfectly until the KitKat software came out...

Chikara71:
I know it just cant be the two of us from such diferent places in the world but, i just cant find any similar in any post or google. It has been almost 3 months from the update an me using another phone...

Well I thought I would post again to close the loop.
After Samsung tried 5 times to fix my phone, checking hardware and trying to reinstall the OS with no luck, they suggested I try replacing my SIM card.
Surprise surprise, it has fixed the problem with no recurrence yet after a week so far.
I still don't understand how the sim card could be the problem, especially as my phone was working perfectly right up to the Kitkat software update. All I can assume is somehow KitKat either had an incompatibility with my simcard (maybe the new sim is technically slightly different?) or maybe KitKat somehow changed something on the simcard, if that's even possible.
Interestingly, I did contact my telco first, and they told me to contact Samsung. As it turned out, the fix was in the control of the telcom right from day one.
Anyway, so far the problem is resolved, so I thought I would post this here to help anyone that may have this problem.

Serious connection problems with my note 4 ...Desperation.

I recently bought a second hand Note 4 in absolutely immaculate condition and at first it worked really well.
then ......
I started being told by friends that i wasnt answering my phone i said that was strange as i hadnt been away from it so i rang the phone myself and got a ringtone on the caller phone but absolutely nothing happened on the Note 4 (no vibration / ringtone ) also no data although it showed full signal bars for both. A reboot made it work again but this now keeps happening and the only way i become aware that it has happened is if i try to access a website on data when it will say connection took too long. this happens maybe 15 to 20 times per day at random.
Occasionally for variation it will show no signal or network and when i go to search it says insert sim card to access network services.... again a reboot sorts it temporarily.
so far i have tried
1. new / different sims
2. running in safe mode (all 3rd party apps disabled)
3. sponge on top of sim holder applying pressure)
4. clearing partition cache
5. Full factory reset
6. flash new rom
7. button press (home for 2 secs then start for 15)
and probably loads of other things i cant remember so now im DESPERATE !! has anyone any idea what this could be its a UK spec 910N phone IMEI is valid i have no warranty HELP me please

Are you sure you have the model number correct? Haven't heard of a Note 4 910N variant before, and the only place I can find it online is on foreign (non-UK) websites such as http://mg.olx.com.br/regiao-de-uber...lares/samsung-galaxy-note-4-sm-910n-128225596
Apart from that, a Samsung 910N comes up as a monitor! (https://www.amazon.co.uk/Samsung-SM-910N-TFT-Monitor/dp/B0002TNVGO)
Just FYI, I'm using a N910C in the UK on EE with no problems.

My mistake it is an SM-N910F-32GB

Are you having issues with bluetooth or wifi as well? My note 4 N910W8 has issues with keeping a stable bluetooth, wifi or LTE connection, and occasionally drops calls.

The batery
Try with other batery, i know, that is crazy but, in my note 4,it fix network conection problem. (no network, no sim, no registered on network) my problem start after use a motorola turbo charger, it damage my batery and (and the signal) but just changing batery the network was fixed. Sorry for bad english
---------- Post added at 02:49 PM ---------- Previous post was at 02:36 PM ----------
I commented that I was the same . wanting to find network said without sim . Sometimes if I showed sign, but with only emergency warning . Change my battery and everything is perfect but I can not understand that relationship can have . Hopefully I can help my advice
