imei and wifi problems after flashing custom rom - Android Q&A, Help & Troubleshooting

wifi & imei errors after flashing custom rom
i own a q mobile noir a2, if you are not familiar with the brand,its the same as micromax a 45(sold in india).it runs on gingerbread 2.3.6.
i recently rooted it but accidentaly deleted some stock apps which i wanted back.so i thought unroooting the device will maybe bring back my stock apps.
i unrooted it but what was deleted,stayed deleted.i decided to flash stock rom for noir a2.i did,got back all the apps,
ISSUE #1
but imei of my phone changed.i have tried many times to repair it with mtk droid tools,maui meta,sn write tool,imei fix., etc, but i dont succeed.my phone is not reading my sim cards at any cost.
when i take out both sims, and check with *#06# it shows the correct imei,which is written on the back of my phone. but as soon as i insert the sims and check imei,the imei 1 is invalid, and imei 2 is some incorrect imei.
please guide me how to get the networks back in my phone
ISSUE #2
my wifi also doesnot work after flashing the rom.it detects wifi network,attempts to connect,but never establishes a connection
also the engineer mode in my android doesnt have cds option(i found about this on internet that maybe this is a fix for my problem but it doesnt work for me.)
please guide me i am very new to this.looking forward to your help.

Your problem is that the custom ROM that you flashed messed up your /efs folder.... apparently some files of the ROM you installed changed some of these settings.... did you do a backup before flashing the ROM??

maui meta,mtk droid tools, i have tried them all.other users say these methods work.maybe i am making some mistake in the steps .
i read somewhere that while repairing imei both sims should be inserted in phone.
can you please tell me step by step what to do with these softwares?
ALSO
is the same problem causing my wifi not to work?or the wifi issue is because of kernel?
can you give me som insight what kernels are?what they do?
thanks

Just flash stock rom again. It's the only way.

are stock roms the original roms which mobile companies give us pre-installed in our devices?
when we have a new device we donot get the imei problem. if stock roms are same as the pre-installed roms,then why so they give imei errorr after flashing?
also,does the imei error have to do something with wifi not working?why does wifi not work too?can you please throw some light on it.
confused

Yes.... stock roms are the roms that are installed when you buy the phone.... the wi fi problem and the imei problem ( i think) are not connected together even if they are found in the same folder ( that is /efs)

i have fixed thew wifi issue,the mac address was messed up ,just fixed that and wifi works.
only network (imei)issue left.
i have heard that best software for getting imei back is mobile uncle tools.
tutorials say i have to enter engineer mode>cds option .in mobile uncle tools for this.
but there is no cds option in it.
any thoughts please?

Did u make out with this problem ?because I am facing the issue with my gionee m3 ,and I have done same as u have done.but got totally screwed..I restored my imei with an app called champlephon.even after fixing the imei issue its not reading my sim card..I hope this app will help u.. If u hav already fixed it well and good..please help me to fix it if u have any idea wt to do next..even after fixing imei its not reading sim cards...

This is why you don't let your buddies do random crap to your phone.
I don't know if you have already flashed a radio or not but you could try it, honestly I don't think it will help but it is worth a shot. I'm fairly sure you lost your EFS, your IMEI and all that good ****, and I don't think there is a way yo recover it on the Note 2 without having a nandroid backup with the EFS backed up into it. You could go the Verizon S3 forums and try their IMEI recovery method.
It's hard to diagnose what's wrong without knowing exactly what your buddy did, if he did mess phone up for good and you can't recover the EFS I would make that buddy buy me a new phone.

How did he flash it? Where did he get it from? It most definitely should not have done this unless he flashed the Odin file in recovery.

What exactly did he flash in recovery? The same file or a different one? If a different one what was it. If it was the same one that's where the problem is.

Were you unlocked prior to him screwing up your phone? If so, I would say try restoring to stock and see what happens.

Soo, i have tryed every single rom on www with build date 2013.06 ++ and on any single one mobile network is not working i get the same message when i try to search for network "error when searching network" i have tryed all methodes i could find on net : galaxsim unlock, efs backup, efs backup on pc,efs backup and restore with Ktoll app, i extacted efs files from a nandroid backup, i matched ril with getril, flashed diferent kernels, flashed diferent modem's, went into sistem debug,changed sim, changed network provider. all of this had the same result NO NETWORK :S.then i went for flashing roms with build date 2013.05.++ and they are all working network is working on them soo it seems this month builds are not for my nob phone.

That's weird, you should wait for a user who knows his way around custom ROMs.
What I would do is to perform as many EFS back ups as I could, placing them both in internal sd & external sd.
I think this is about trial & error, but then again what the hell do I know.

What carrier /country are you with? Is it possible that there are no APN's that come with the latest ROM's which give you connectivity? That's a huge long shot, but I can't thing of anything else sorry. You've tried all I would normally suggest.

baseband unknown?
Sent from the little guy
even mine when i use AOSP (Carbon ROM in my case) the network will just suddenly drop off and it doesn't come back even after reboot/toggling airplane mode but i dual booted with a samsung rom and just rebooted to that it was working then! any idea why the network will just stop working?? any fix for this!?
Carrier is Orange , country Romania, baseband I9100PBVLP , and if its no apn set what shall i do??
Sent from Maniac`s GT-I9100
ok , i reflashed RootBox-JB-i9100-V4.1, i set apn to original one, and now after reboot i get signal for 3-5 seconds then i lose it again, in phone status i see signal strenght is normal network carrier unknown, network tipe unknown, restored efs again, i am soo angry right now cos i am unable to find the origin of this prolemno matter what i try, i go in Settings>>More>>Mobile Networks>>Network Operators ,when i click it it say Erroe while searching for networks and if i click Choose Automaticaly it says Cannot connect to this network right now. Try again later.....and again after reboot i get the network working for 5 seconds, i see carrier and all then it disapare and get status unknown, somehow the rom cacnot stick to the network or somehow i get kicked from the network...
I think its the universal ril that cm released. I'm on pac26/6 and has pants sig. Same as rootbox and pa3.60. If I go to stock custom like neat. I have no problems at all. Sig is better "2bars" better. Only difference is the ril.
and how do i change or flash a stock one on the custom rom?? i may ask some nob question cos i rooted phones 1st time few days ago and dont know much, thanks

Thought he was on rootbox v4.1. go to stock custom say neat, alliance. They have no problems with sig. Iv bin on all the good Roms in past week and custom 4.2.2 sig has changed for the worst. I thought it mite be sig in my area but its not nothing to do with masts or mobile network. This is what makes me think ril. Btw op don't flash ril/modem on custom Roms or bye bye imei :thumbup:
Also don't use get ril its not working.

Please someone could help me would be very grateful.
Did you try flashing a different ROM when this happened?

no friend makes unlocking the APK SSU and had the signal good for a few seconds but then no longer had signal upgrade to 4.4.2 via Odin and is still the same. I want to know if I can retrieve the IMEI again.

Does your imei show as blank or as a 0049 number?
You never made a previous efs backup?
Did you try flashing a different 4.4.2 ROM than the one your phone already had? Did you do a factory reset in the process?
I am curious of everything you have done so far
You may need to contact @cvxcvx for help. He does Samsung efs repair that works. Seen him help many.

This appears when setting * # 06 #. the phone had the version 4.1.2 and upgrade to 4.4.2 before updating but I was just thinking the IMEI update would be solved.
If you don't have an EFS backup, probably time to contact cvxcvx.pl

I have no copy. is cvxcvx.pl?
http://www.cvxcvx.pl/en/ I have seen him remotely fix multiple people's Samsung efs. I think he charges around 20 euro.
I believe he remotely logs into your device. Your device never leaves your hands from what I understand. I've seen at least 5 similar cases on the n7000 forums where he fixed it.
He is polish.
It looks like In your case its not 99% fixable like if you had a 0000 or 0049 imei. See this page as well

To me it looks like your situation is more similar to the 50% that he says.

Worked for me , i never had a problem with data. On setup screen check agree and don't send diagnostic data.and once in rom make sure to check that apn is selected.

Okay I'll see
I take it you are talking about cellular data not your stored data as in files right? If its the foremost then I suggest checking your APN settings.
nothing is happening I cant fix my data I even fixed my apn codes it still wont work it shows I have bars but no 4glte Icon or 4g what so ever
