[Q] T-Mobile Samsung Vibrant (Rooting Question) - Vibrant Q&A, Help & Troubleshooting

(Mods, sorry if I am creating a new thread of something that is already established but I couldn't really figure it out)
So I have a t-mobile vibrant running 2.2 which was previously running 4.2.1 rooted... recently the phone just turned off at night when I was sleeping and then next thing you know it doesn't make calls or sends texts and gives me notification that it is unable to connect to the network. I Tried to troubleshooting is several different ways and nothing worked out but finally figured it out that the IMEI number was messed up and it had reset it self to Dev IMEI and obviously that didn't match the IMEI that is in the back of the phone.
So after extensive research on how to fix it I just ended up taking a chance by unrooting and returning to stock and thankful it saved my phone.
The real questions, before I rooted the phone I didn't know that once I root the phone I was supposed to back up the /efs folder so in case the above mentioned scenario was to occur. Now if someone can please help me, before I root the phone again, what are the steps I should take to assure that I don't run into a similar problem again and if I do run into that problem what resources should be backed up so I can resolve the issue without much pain.
I would truly appreciate all you help.
Thanks.

I've never heard of having to backup the /efs folder after rooting...has anyone else?
I've rooted and unrooted my device a-helluva-lotta times and I've not only never had this problem, but I've never backed up
my /efs folder afterwards.

I need some help - No 3G Signal

I recently just flashed the .pit and .pda tar from this:
http://forum.xda-developers.com/showthread.php?t=1349895
to get to stock EH03 and work my way from there
My problem is, after booting my phone I have no 3g signal. I tried *228 and reactivating but that doesn't help. I can receive texts and calls but still no data. In my About Phone : everything shows EH03
Could anyone give me some help? I'm a little worried..
EDIT: Found what I did, I accidently had Phone EFS Clear checked when I ran everything... do any of you guys know how to fix this? *228 doesn't help me out
By looking at my MEID from Settings -> About Phone -> Status , it still seems to be there reading
DEC: 268435459603183741
Hex: 0xA000002430947D
This does match the number underneath my battery.
* I am trying to get root access now but SuperOneClick seems to be "not responding" when on Shell Rooting Device Step #7 - WaitforDevice
* I have an old phone lying around, but it's not a smart phone and I don't want to try activating that one and reactivating this - I hear I will lose my unlimited data..
Maybe you can try this link?

If you do activate another phone and reactivate your fascinate, you can get your unlimited data back, you just have to call them. I think there's a window where you can reactivate a smartphone and retain your current data plan but I'm not sure what it is, probably 2-4 weeks, so if you're just reactivating it real quick it wouldn't be an issue. Just the hassle of calling and having them fix it.
I have no idea if that would even help your issue though, I've always seen checking the "EFS clear" box in odin highly warned against but I can't say for sure what you did by doing that, maybe someone else knows, or google it?
I finally managed to get root access.. I'm going to look into both of these threads:

and see if I can magically fix it.. Thanks for your help so far guys.
EDIT: by #06# .. it shows my MEID as 45035996880868477 ..
I've looked for an /efs folder in my phone directory but it seems I don't have one. At this point I think I am screwed. I can't try what any of those links say because they require that you have the EFS.
As of now, I'm stuck with a stock EH03 rooted device with no data only call/text.
I'm guessing you probably already saw this thread? Did you try activating another device on your line, then reactivating the fascinate?
Yeah I already saw that thread, but thank you for the help.
I took my phone in today since I do have the warranty and I got it sent out.
Also, I got a Galaxy Nexus since I was due for an upgrade.
Thank you for all your guys' help though. It really does help.

[Q] Flashing custom FW, returns to stock.

Hey all, before I say my problem, firstly I have no idea if this is the right section in the forums so apologies in advance, secondly, I have held out for 3 days trying to work out various issues before I posted. I probably did just miss one thing or misread another but no matter how much I look, no idea what as new to this. Thanks in advance for your help.
Basically, wanted to flash some custom firmware to my phone, I have been having many issues with backing up on Kies, seems to be something related to my USB's and my computer, it keeps failing during the backing up of programs. I ended up giving up on this, made a titanium pro back up of System files and of programs, also made a Nandroid backup, both on my internal phone memory I believe. Have root access, installed busy box and such, backed up some other stuff using EFS Pro, now I am completely confused, I have followed a few guides dotted around the internet, tried to install some custom firmware, it was Carbon Rom 4.2 I believe. I went into the CMW menu, wiped data/factory reset, wiped partition cache, and wiped dalvik cache, installed the rom from my internal phone memory, as it would not find it on the memory card when I tried, and now after two attempts of it seemingly doing it, on rebooting the phone, I go back to the Samsung firmware.
I have tried to read up as much as I can but obviously I am missing something here and no amount of guides or google searches have hinted at my problem, could anyone help? I know people asking constantly for information on how to put on custom firmware will be irritating, but I have genuinely taken this as far as I can alone Cheers
Now after formating something under mount/system, my phone is stuck on the logo screen, reinstalling the ROM does not work either, no idea what to do now
reflash rom, wipe data and voila.
Hey, thanks for the reply. By reflash rom, which way do you mean, am pretty confused still. The rom I download basically bricked my phone, I don't know why, I think to recover it I use ODIN and get my stock software, so is that what you mean? Or can I somehow use my Nandroid back up..?

If you have a Nandroid restore that or flash your original firmware via Odin .
Never restore system files after a firmware change with TB .

Ok here is the situation now, I have made things 100 times worse, I possibly should not of been doing it this late... I followed guides exactly though and there is definitely something not working right with this phone, I just don't know what, all I know is its very temperamental with connecting to computers and will fail doing the custom firmware flashes half the time, no matter what I use, even using the stock ROM i got from samimobile has caused many problems. It might be me, I don't know, but in my frustration followed some advice on a forum and I think I formatted the mount/system. SO obviously I lost both my back up's. My fault and can live with that, phone was bricked and had to do that to get past it I think..
But now no matter what kernel I use and have tried quite a few including my original one, I am unable to connect to my home wifi. It definitely is not the wifi, it worked just fine before I flashed the phone and has been working with it for 4 months, now whenever I set up the phone its constantly stuck in this obtaining network ip infinite loop. No fixes I have used have helped at all so far Sorry to keep asking stuff, I am just literally at the end of my tether, was up until 7am messing with it to no avail.
Just to reiterate a point, the reason I wanted custom firmware was because the phone was crashing randomly and just dying on me and also the speaker had lost like 90% of the volume when I wanted to play music, also it would not connect to my computer with ease, now obviously before I did anything it had issues. So that is why I feel something might be wrong, not saying I did not break anything myself, just the process of flashing the firmware has been pretty straight forward once I did it a couple of times, it has just been failing and bricking every other time, so I am not sure what the problem actually is, did I miss a step, did I mess it up? If not what has. Please helps guys. Regards.

Usual reply if you did not know what and why and had never bothered to read the faqs and guides before flashing .Then its nearly always user error .
Best take it to a service centre and pay for a repair .

Found out something really handy
Hi guys,
TheGS3 has 1 huge trick when u got stuck in firmware, CSC, etc.
Especially when u used some super usefull toolkit (like me)
I used the Galaxy S3 Toolkit, option4 (ALL in ONE) just push enter 2 times
1 to start and the last one to exit...
Got all the issues i read on hundreds of pages searching for the solution.
Accidentialy i found this morning (its 4:45am right now and busy with it since 15:00)
Start Kies, connect GS3 with USB kabel and when it says not connected take out USB
Dont plug in USB for a while...
In KIES go to Tools and irmware upgrade.. Remember, DONT plug in USB
It will ask u for your model nr which is printed on sticker in baterycover
Confirm and it will ask u S / N' which is printed on same sticker
It will start downloading firmware and u will be guided through update progress
Good Luck to y'all.. Time to go to bed.......

[A] Simple IMEI Repair (efs folder repair)

Hi All,
I thought I’d share this as I’ve been pulling my hair out with trying to find answers to this, and sending it to old Sammy was the next option.
After trying everything on every forum, trying the QPST method, trying to use someone else's efs folder (which changed the serial as well) and every other complicated as hell method everyone had suggested, nothing worked expect his which I’ve not found mentioned anywhere as a solution to this (or any other) problem
In the Samsung Kies application under "Tools" there is "Firmware Upgrade and Initialisation,"
With your device unplugged (it will say not available for this model if its plugged in, don't plug it in until it tells you to when in download mode) select this and run the what it tells you to do,
After this is finished you will have a completely fresh install of the latest officially released firmware (for your original build eg. carrier branded) with original serial number and imei number :laugh:
It’s really silly how simple this is yet has not been mentioned or attempted by anyone else, or if it has, not mentioned by anyone else.
I crap you not…
Thanks,
[edit:] just as a note, I got into this problem by not backing up the efs, the world would be a much nicer place if everyone just backed up their efs :laugh:
This has been posted before and does not work in many cases .
Although the method can be useful to restore to original firmware .
jje
Yes, flashing a stock rom will sometimes fix the problem of the efs folder not being mounted or read. It won't fix a corrupt partition or damaged files.
The stock rom you flashed didn't contain any efs data so it isn't any substitute for a backup, you were very lucky it worked.
To my tests this work only when efs is completely empty while upgrade if not it doesn't work
sent from the state where Marijuana is NOT illegal !
Same problem
hello guys,
Well I'm to tell the story of how my aunt damaged apparently her phone
At first the phone is a samsung galaxy S3 from movistar (locked), and she bought a freaking iphone 5 to give the S3 to his husband and there it starts the problem he's in another company so she goes to a store to unlock the phone, the guys on the store supposedly unlocked the phone. So when she arrives home, she puts the sim into the phone and SORPRISE it says emergency calls only and not registered in network. After a week she calls me and hands me over the phone.
My surprise was when I put it in recovery mode, it says flash count 3, and then i did all these terrible things with thephone.
1) Flash it to a stock movistar rom 4.1.2.
2) Sorprise the IMEI sayd null.
3) Searching in the web, found the ariza patch, and I patched it without saving the efs (big mistake).
4) The phone imei's became 0049.
5) So I flash it back to the rom they put in the store and the imei went back I make sure it was the one on the back of the phone.
6) I still stuck in the emergency call not registered in the network thing.
7) Now I rooted the phone erased the whole content of the efs directory (this time with a back up).
8) Did the tutorial thing with samsung kies and I'm back with the movistar rom with the 0049 IMEI.
I don't what to do at this point besides going to samsung and send it to repair I really hope they can fix it at a low price.
Sorry for my english, I'm trying to improve it.
Best Regards
Andy Serrato... the spaniard
Start by reading the stickied faqs and guides EFS/IMEI sticky for one or just pay for a repair .
Galaxy S3(GT-I9300) having the same problem! HELP HELP HEEEELP PLEASE!!
Very unfortunately. this didn't solve my problem, the phone's Serial number is still that auto generated junk, and the EMEI is 00499901640000 as before. I had 4.1.2 on my S3 and Kies has updated it to 4.3 without resolving the issue!
can anyone give an idea on how to surely resolve this issue please. its about 3 months now ever since my phone got screwed up!
Pay for a repair
Perfect
I cannot believe this worked, but it did.
I messed up somehow by trying to flash the wrong cwm.tar file (for i9305) I needed i9300 of course and odin stopped halfway and got stuck, i then pulled the cable out and everything got very messy,.. i kept getting lots of errors etc. i somehow managed to install an old cm11 rom which worked lovely. BUT I had no baseband, no imei, no network, no number, nothing, #*06# or whatever it is, wouldn't work. nothing.
I then started to figure out how the efs filesystem worked, then foundout kies has an emergency thing where i guess they look into there database what your imei was when the phone was built. this would not work because I was using a custom rom (i think) but then I stumbled upon this post. thank goodness!!!!!
It's just restarted and internet, signal, imei is back, baseband version is back. all in order.
however, i think i was also very lucky, but for those of you who are in the position i was in, but this doesn't work, I do think there are ways to get an old efs going again and modify it to your "should be" imei,
if anyone needs an IMEI, I can give you one from a phone i had stolen in vietnam, (not sure its even legal to give it out but whatever)
thank you

WOW! This worked! I had been struggling for 3 months with my Note 2. Been flashing rom after rom and got stuck in boot cycle. Actually broke down and brought phone to a cell repair shop. She said it just needed a new battery. $50 later got my phone back. She had put stock AT&T rom on it but lo and behold, my sim card didn't work and my IMEI was null. I brought it back and she had it for a week and then said there was a hardware problem AND my USB port wasn't working and it would cost more to fix than it was worth, so she gave it back to me no charge. So I spent next months trying other roms. reading up on EFS folder, even learned some ADB stuff. To no avail. And BTW, my usb port seems to work fine. Finally this afternoon after Turkey Dinner, I stumbled across your forum message. And 15 minutes later I was downloading a repair and the son of a gun fixed everything. I verified it with a Sim card - perfect ! Apparently Samsung has a database of phone serial numbers and what IMEI code goes with them. Fanatastic! Thank you. I will be writing a serious neg review of that cell phone repair place soon.

Lost IMEI please help recover S4 i545

I have lost my IMEI after flashing a ROM. I did make a backup of my efs folder, but unsure how to use it to get back my IMEI. I could really use help with this, if someone could PM me and maybe help through skype that would be great.
I have tried every method I could find on XDA without luck. Sadly the replacement phone is an ME7. I have until this afternoon to try anymore possible fixes. My IMEI show's up now in the about phone, but I still have no 3g/4g or service for making phone calls. On top of that the phone likes to think it is in Airplane mode at all times and is basically impossible to turn off. Again I do have a copy of the original efs folder, but I fear that may do me no good. If anyone else has ideas that may help me solve this matter that would be great. I am willing to talk via thread, PM, or skype. The phone is currently unrooted and returned to stock to be sent in for warranty.
Thanks,
Muraki

[Q] I think I'm hard bricked

Ok, first of all, I take full responsibility and made some really stupid mistakes. I consider myself an experienced Android user and have been flashing ROMs and radios since the OG Droid.
I am, however, new to Samsung/Touchwiz, and made an error I'm trying to determine if I can repair.
I have not flashed any custom ROMs on the Note 2, but I was unlocked/rooted with CASUAL. I was having some issues with my proximity sensor and my capacitive button lights, and decided to ODIN back to stock. Here is where I screwed up, I think. Instead of flashing like normal, I think I want a completely clean slate, and I checked Nand Erase. I know, please don't bash me, the brick sitting on the table is punishment enough. I was thinking of erasing backups, as in Nandroid (Nand) backups.
Well, everything flashed as normal and the phone bootlooped. No biggie, booted into Recovery, and it gave the warning it couldn't mount the /data partition. I did a factory reset from stock recovery, and everything seemed fine. The phone booted correctly, but it wouldn't activate on Verizon. It finally allowed me to skip set up, and I found the dreaded "Unknown" IMEI.
No, I didn't have a back up of the IMEI. I began reading and studying on ways to fix this, and it seemed simple enough, but I couldn't get QPST to recognize my phone so I could repair the IMEI. The computer could see it on COM5, but QPST kept saying No Phone.
I tried a few other methods, including EFS Professional and NV Item Reader/Writer. But everything said it couldn't communicate with the phone. I made sure I had it in the correct mode in the Phone Util hidden menu, checked USB cables, ports, and drivers a hundred times, with no joy.
Then on a whim, I checked my /efs folder with ES File Explorer, and the contents are empty. Not sure how I erased all the contents, but now I'm pretty sure I'm screwed.
I wanted you to know my steps, before I started asking questions.
1. If I can get another working Note 2, is it possible to use a copy of that phone's /efs folder on mine? If I can get QPST to work, I could then use it to inject the correct IMEI back into the folder.
2. Is there anyway anyone here could upload their /efs folder so I can try it?
3. Any suggestions on QPST and getting it to recognize my phone?
4. Am I just completely hardbricked and out of luck?
Thank you.
I know there are other similar threads, and I have searched...a lot. I'm just trying to figure out if I'm missing anything.
Also, I've found some IMEI repair services online that will fix a missing or corrupt IMEI for about $25 plus shipping. Does anyone know of a reputable repair service for this issue? I'm getting somewhat desperate to get this fixed. I'd be willing to pay someone here to fix it as well if you have the know-how and equipment.
Thank you.
Hi,
There are success stories on this issue in xda...would suggest you to read xda articles on this issue.
