Hi all,
I know that many of you have the same problem and I found that you have the thread about it.
But it's too long for me to follow up. So anybody to tell me what exactly I should do for this problem? When I press volume down + power to go to SimUnlock process, it has a error: MCCMNC, CID failed. On the phone, It can be searched the network.
Please help me, sorry for my bad english.
Thanks and Best Regards
Nguyen
well since you are too lazy to read whole thread...
return the cellphone and get a new one.
Btw, did you tried to unlock it after OTA, or you have not did the OTA upgrade yet?

I did it with OTA not upgrade yet.
You know, the thread about it is too long and sometime I read but cannot understand, it's hard for me to follow up to find the solution. So I want s.o help me clearly and exactly what should I do for this problem, and maybe, it helps others too.
Regards
As I said, return the phone and get a new one. At this moment there is no fix for unlocked phone that is not connecting to any network.
Personally I've tried to find the answer for wether OTA solves the issu BEFORE unlock, since from reports I've read that once unlocked and not working OTA does not helps.
Also iwas trying (unsuccessfully) find what OTA really upgrades.
Good luck.

sorry but I have to laugh, dude you need to read the entire post to understand the severity of the issue.
return your fone cause its done no service no fix.
I tried to contact with Tmo but there's no reply from them until now. Further more, many people got this problem too and no solution for this.

I ended up bricking a co-workers Wing yesterday and after some internal research, found out that there is a recovery rom that is developed by tmobile to reinstall the original oem rom. I am working with internal departments to allow the rom to be available legally right now. Prod development has the rom currently on t-mobile's intranet. Hopefully they will allow us to use it and essentially make it available to the general public.
No more bricked wings!!

Well that sounds good, please keep us posted.
Incidently it isn't nice to tease the animals . . . .
Well, I am just looking at the legal concerns of uploading the rom without express permission. Maybe I could do so on my home pc.
I now have a copy of the tmo wing RUU but I am trying to get tmo to release it to the public before I send it anywhere.

Just looking to try some different ROMs out, but I have no reliable way of backing out if something screws up. I've tried taking dumps but have been unsuccessful.
How'd you get t-mobile to release it to you in the first place? I'll gladly call up and get a copy for myself if I knew what to ask for without sounding like I want to void the warranty.
Xavier6303,... I would really like to get a copy of the t-mobile wing ruu. I bought a phone from an ex-t-mobile employee over ebay, and the bluetooth modem does not work correctly,... I eventually got though to t-mobile's level 3 support and they said my ROM version was old but could not give me the new one. Said I needed to replace the phone.
I have ROM version 4.10.531.3 WWE, dated 03/15/07,... he said the latest t-mobile has is 4.27....
What version do you have? Can I get it from you,... Pretty Please.
What!?!?!? They have a NEW rom and haven't released it? With all the problems this ROM has they are sitting on it?

To my knowledge this is the stock ROM that comes installed on the wing, not an upgrade.
Does anyone else have it or know how to obtain it from tmobile? What could we ask for that would make them give it to us without making it sound like we're going to do something that might void the warranty?
Edit: Sorry. Just realized that I had pretty much already asked this... long week... lol
Xavier just upped it here.

T-Mobile (Official?) Rom At last!!!!
http://www.mediafire.com/?21rtyxwyuyj
Posted from another thread (http://forum.xda-developers.com/showthread.php?t=321717)
of official T-Mobile Rom (original)
Enjoy
so this is the real deal?
My DVP decided to crap out yesterday for no reason. I read the "how to unbrick your phone" thread and was able to revive the phone using the TMO ffu file. It crapped out again so it looks like it's the SD card. I will be doing the flash again but does anyone have that file for AT&T instead of TMO? Thanks in advance.
It might be possible to use the TMO ffu, update to 7720, then use cabsender to send the ATT firmware bundle and turn it into the att version (as that's the only file that differentates the 3 versions)
It could also possibly brick you to the point that nothing can fix it, so I'm intentionally not posting the direct link to the files, but there are links to them if you search around for the VP on xda.

I think I'll give it a try, can you point me to the right cabsender? If it bricks I really don't care, went out and bought a Lumia 900 and actually like it. Thanks for the help.

I'm only make a (hopefully) educated guess on the whole thing, I believe there's only 1 version of cabsender(?), but it's the actual cab that i'm talking about that i'm not linking to.
Since the potential issue of permenetly bricking isnt an issue(?), look on the VP page on the xda wiki, it's listed there.

First, if you already had an unlocked phone, why would you do this?
Second, there are several warnings about this not working and possibly even screwing up phones. If you would have read, you would have seen them. Trying anything without first reading is your own fault. The OPs of these "unlock for free" threads should be shot for not putting HUGE disclaimers up about the possibility this could screw your phone up but it is still your responsibility.
And third, you are probably screwed. The people that I have seen this happen to have not been able to unlock their phone with any method or code. Though, you could always try.
Unlocked already, and you tried to see if something else would unlock..hmmm WHY?
Are you just doing things to just do them? I am confused.

Hi after flashing a rom not on xda my phone's IMEI became erased. unfortunately the EFI backup that I had wouldn't fix either. I tried going back to stock using SmartSwitch emergency recovery. Still no fixes.
Please help my phone cannot use cellular service!
Any idea Im all ears. I tried various methods for older Galaxys around the xda, none worked.
I know my IMEI and S/N how can I fix it.
Please help!!!!

With all do respect.... I don't think he was bashing anyone....he was just saying he flashed a ROM that wasn't posted to XDA...more than likely there wasn't any other option to ask for help elsewhere since XDA is very helpful with responses from developers and others.
I was wondering if anyone that is overseas (outside america) could share an EFI backup partition with me so I can fix my phone. Maybe that would fix.
keep watching the echorom thread someone else had the issue as well.
I cant they banned me from seeing their forum when I reported the bug.
O I see. If something gets posted that might help I'll let you know. But 1 thing I saw already is trying to flash multiple times with Odin
It might not work the first time. Or the second... or the third. Try like 10 times in the mean time until someone can help. If all else fails there has to be a way to make a working imei again since you know it anyway

This happened to me before in a old Tmobile S3 (T999) I had only edge network...
It was a headache and I was only able to put it back working going to a store that had BOX for flashing and do it myself with their box
and rewrite my IMEI manually during flash, as they were not able to do it (more say didn't have patience) .
I dunno if there is a easier way to do it... but this was how I fixed mine back then. But one thing is true, I lost a lot of time back then trying to fix it and if it happens me now again I would do a quick search and if not quick solution, try to find a guy that owns a box as it will literally save you days and sleep. However there are excellent devs around so they might be able to help..

Would u have any suggestions on where I could go to fix?
Quick question. What csc is in your phone now? Have to tried changing it again with a new one or the one that was originally on it when you got it? Like a flashable zip? Cos it looks like somehow the one you used must corrupt something in the efs... which is bizzare

I went to local store that usually unlocks/fixes phones, but I had a friend connection around.. hence they allowed me to go inside and do it myself.
Try to search 1st around if there is a solution, as it might be... I can't remember how it happened to my phone, but I was flashing lots of ROM without a problem and then it happened for some reason. There is a reason for it, however I couldn't find it as my knowledge is limited. I do remember that I tried, stock, odin, kies, whatever... and nothing worked until I went to try with a BOX.
IF you can't find a quick solution try to search around physical stores that flash phones, as they usually have a BOX and probably they might pull the S7 image already for their box... try to search a friendly one and take the purchase papers with you as most are not very comfortable with anything that might involve IMEI if you odn't know anybody.

It was the German based CSC
G935FDBT1APC5
However I flashed back STOCK which has
G935FNZC1APAX
The bizzare thing is my phone appears to still get a signal, but emergency calls only. When I #06# It shows 00000000000000 for 2 MEIDs. Which is weird as I don't have a dual sim model. This is even after Odin stock, no root.

Fair enough, I still have the original purchase, I got it from overseas, receipt, and sticker still on the phone. Even the box. at the same time i was wondering if anyone overseas, (not in the usa) would be willing to backup EFS and PM me with a G935F because I could use that meid in the usa. I have no intentions of going overseas to Europe anytime soon but I might go abroad if its oceana or Asia.
I've done a bit of research, searched through threads on this forum, and I still have no idea what I'm doing. The last phone I rooted was a Samsung Galaxy S2 Skyrocket.

First which firmware are you on now? 10i, 10j, 10k, what? I think 10k is not rootable. But... If you have older firmwares then you can root with dirtycow method. it is not that hard. I think the hardest part should be to try to flash the twrp (but even that was easy at least for me an average flasher and tester). If you have any issues, the system will usually restore to the original image as a last resort.

The 10j kdz version is to be flashed with LG UP if you needed it. but up to now it is better you dont move further from 10j, because 10k is not rootable (i believe I've seen). If you want to have 10k you can flash 10j and then flash via twrp a zip of the stock rom with 10k

T-Mobile won't unlock it for me. The day there is a balance owed on it. And when I tried the unlock app. It say failure in processing the request. Please reboot and try again.. If you can walk me through this it would be greatly appreciated. Thanks all!

Why did you reply to a post from last year for this?
Rooting has nothing to do with network unlocking the phone (and if it's on 10t or really anything past 10k it's unrootable anyway).
Your best option is to get T-MOBILE to unlock it, otherwise there are some other third party websites which may be able to unlock it for a fee.
