[Q] Avoiding losing IMEI

Hi everyone, i got some questions about the IMEI that i don't know so much about How do people lose their IMEI, get blacklisted and can it be fixed? does it depend how i/they flash things? i have flashed so many things and never losed my IMEI but do i need to worry ?

no need to worry.
it wont walk away
only with a fail during unlocking or rom manager usage on the wrong way will lose your IMEI. no need to worry

flash back to original dutch rom for your provider(vodafone, kpn, telfort, tmobile)
and try again.
try with different simcard from the same provider so unlocking isnt needed and you can check or it is your sim or phone.

what do you mean with backlisted ? couldnt find the dutch word for it
Sent from my GT-S5660 using xda app-developers app

In the US T-Mobile is now blacklisting imeis of people that buy their phone on a payment plan and then stop paying. They are also blacklisted occasionally when reported stolen. These phones sometimes make it to online sellers and work for a while then stop because the original owner stopped paying there bill.

Unlocked att note 2 reception issues on t mobile

This is my first post on xda. Ive searched high and low for a solution. I get very poor reception on my note despite my friends having full bars. I understand I wont get full speeds, but shouldnt I atleast get consistent enough reception to talk and text? Ive also popped in an att sim in to confirm it wasnt hardware.....consistent full bars. Ive tried t mobile roms (jedi x), modem flashes and factory resets. This is really stumping me so I would be very gratefull for any advice or suggestions.

I also had my t-mobile sim replaced to confirm it wasnt the sim card. I also popped my friends sim who had full bars on his s3 in my note. He also had little to no reception

I have the same issue. I'm wondering if flashing a tmobile modem will fix the issue.

I was plagued with weak reception, even got AT&T to send me a MicroCell as calls were dropping at home. I tried rom after rom going from Android 4.1.1 to 4.4.2 and they all had bad reception. I read about people putting wires and things in the external antenna port, but decided against that as I also read that LOTS of people damaged their phone doing that and had to replace the phone. Well, I decided to wipe the phone and normally I wipe Dalvic Cache, Cache, System and Data, then install a new rom...but this time I was going to go back to the original recovery and rom and start all over so I wiped the Internal Cache as well this time, BUT I could not find a stock recovery to install, so I went back to 4.1.1...to my surprise, once I rebooted my reception was strong! I then went back to my nandroid backups and loaded various roms...they were all strong!
Point is, make sure if you are having reception problems to wipe the phone completely (remove your SDCard if you don't want to lose what you have on that) then try reinstalling the rom and see if your reception comes back. Mine has been solid since I wiped the Internal Cache with TWRP and this is the longest I have had good reception in a long time. I am back on Android 4.4.2 and my reception is working great again!

Flash your carrier modem people....done...
And that can even mean a 2 year old modem ....but...
It "must" be the carrier you currently use....g

[Q] Is this blocked IMEI on my Note 2? im confused :(

Im a little confused and im wondering if someone can help me out or if someone is going through the same thing i am.... :crying::crying::crying:
So i just got a Galaxy Note 2 from my fathers friend at work and i am wondering is this considered when they say being a blocked IMEI cause its a little confusing...
So I have T-Mobile and i received the Note 2 it is not rooted or anything and the IMEI matches the same in the "About Device" and in the back behind the battery so anyways i go and pop my micro sim card in and notice right away it gets no service it just has a circle with a horizontal line accross like seen on the pics and the lock screen just says "Searching".. i go into mobile networks and try to manually select the T-mobile network and it just gets stuck on "Registering to T-Mobile" then i get an error in my notifications that says "No Service Selected Network (T-Mobile) not available" so right away im assuming that the IMEI must be bad so i call T-Mobile give them the IMEI and they tell me its NOT blocked so now it gets confusing.
while i was still messing with it i decided to turn ON wi-fi and all of a sudden the wi-fi calling feature turns on and viola! the circle with the horizontal line changes to empty service bars and in the notifications dropdown it now says T-Mobile so i go on and make a call IT WORKS! send a text IT WORKS receive calls and texts ALSO WORK! now isnt that wierd?
what do you guys think might be wrong with the phone is the IMEI really blocked but if it is will i be able to make calls and send and receive texts i dont understand please some one help me any advice will be appreciated.. :fingers-crossed:
Thanks (here are pics of screen shots)

Try switching the phone to 2g only ! *#*#4636#*#*.

Try calling tmobile with a differnt phone.

Generally, when your IMEI is blocked, you'll have bars and even data. Your phone just won't work. So I doubt it's that. The fact that WiFi calling works tells me that the SIM reader works. Do you know if the phone was taken apart? Maybe the antenna is messed up. Id just try going somewhere else to use your phone and try.
Possibly root and flash different modem?

The sim card reader does work cause sometimes out of the blues the phone will register on the network and im able to use it fully as it should and then it goes back to having the little circle with a line accross it.... today it behaved preety good it gave me a good amount of time of usage but it would still randomly cut off and come back on..... as far as being opened im starting to think it maybe was opened or something cause it doesnt have the "VOID" sticker on the screw in the back like it should..... and maybe what u said about flashing a different modem how can I check what modem I have now?? Cause the phone was rooted and had a custom rom but I restored it back to stock with Odin not sure if doing that will restore the stock modem or not.
Thanks for all your help :thumbup:

I don't think there actually is a void sticker.. When I opened mine up, I didn't find one . I could have just over looked it possibly. Just try flashing JediM14. Comes with everything you need much better than stock. I'm thinking maybe tmobile is working on your area so you have intermittent service. Could be anything. I'll try to help you look into it. The sticky for the modem, ,facotry img and such is in android development. I think the sticky thread is in top three. It's obvious

im having same issue but i can actually make calls and get text, the data side isnt working , sometimes it kicks in but its more on no data than on
im calling for a replacement tomorrow this was a replacement from a bad usb port phone i sent 2 days ago , tried everything and i know its not network cuz everyone in my house has t mobile . hope you figure it out as i gave up

JediM14 comes with the new MD1 firmware. Everything is for Tmobile. During installation, I think aroma gives you options for modem..not completely sure . but if you have tmobile, I'd stick with tmobile modem. Does anyone else have tmobile at your house you can compare signal to?

I actually just updated to the OTA MD1 update and still the same and my wife has T-Mobile aswell she has an iphone 5 and she never looses service here, not too mention we get LTE already in our area but she always has full or almost full bars, as for me as im typing this now this is what mines looks like but yet yesterday in the night I was getting service and 4g LTE
Im starting to think maybe its a hardware problem with my cellular antenna cause my wi-fi antenna works just perfect or what else might it be?

As long as you're stock and unrooted, you might be able to get a warranty replacement. I know you're not the original owner but it really depends on the rep that you get on the phone. If you get the right rep they'll warranty it based on the fact that no matter who originally purchased the phone, there's no way it could be more than a year old. Or, if you have the premium handset protection, you should be able to get it covered under the extended warranty that it offers.

Call Tmobile and tell them your situation. They'll reset your connection to the towers and it might help. They've done that for me. Just ask for like a connection reset. Even better if you just told them what's happening.

Could be antena problem. Had that happen to me with my skyrocket. The one end was not connecting to the right place. Somebody accidentally cut it off when I had the speaker fixed.

Could be this. I bought a replacement loudspeaker that was apparently for the T889 (which it wasn't)..[Most loudspeaker modules that say they are for the T889 are missing the third contact.] It was a missing a antenna contact which totally killed my reception. Try to take it apart and look at the loudspeaker. There should be three white tab looking things on the module itself. If there's only two, then that's most likely the problem.

[Q] Issues with O2 Mobile Internet (UK)

Hello folks,
I seem to be having some strange issues with mobile internet on O2.
I have been with them since October 2012 when I got the GN2 and everything has been fine up until 1 maybe 2 months ago when I noticed by phone was connecting to H+, which I had never seen with O2 in my city before. Normally it would always be on H, or occasionally 3G... both of which would work no problems. Now, I know what the different connection types are, but the problem is that now whenever it’s on H+ mobile connection around 80% of the time it’s either super slow, or simply doesn’t let me load any web pages or refresh any apps that require data connection. I often have to search for the network again just to get it to work. When it is still on H or 3G everything is fine... it’s just H+ that seems to be causing problems.
Also, around two or three days ago I also started having problems sending and receiving texts.
I’m on Wanam v2.9 with old DLK7 modem, however I was using this long before the problem first started so I don’t think it’s the cause. APN settings are same as always and I took the SIM card out, cleaned it and made sure it was in properly but all to no avail.
I will try calling O2 later, but their customer service is notoriously crap so I thought I’d ask here first.
Cheers,
Lee

Try using dmc3 modem see what happens. Sounds like a network problem more than anything

Flashed UBDMB1 modem and it seems to be working consistently again. I just hope it's not a battery killer! :silly:
Previous modem must not have liked HSPA+

I think if you're having issu with your antenna and already try other radio, modem, etc, you should think about bring it back to the shop... have you try complete wipe/factory data and /system reset? Or you could try to completly wipe every file in your phone, until you can only boot in download mode, after this, reinstall your stock firmware, recovery and modem with Odin.
Sorry for my english, I speak french!
