[Q] IMEI changed after flash

Installed the CM7 rom as usual but
my imei was changed to 000000000000000 and can not make calls and send sms
(Although not show signal, you can
access the internet). In the system
does not contain the efs folder and
had not backed up. Is there a
solution?
not want to change, I know it's
illegal, I "only" repair the original. Yes,
I googled before posting, but found
nothing satisfactory. thank you and sorry for my bad english.

that was a bug of the rom which was fixed
try flashing the firmware through odin

thanks for the reply. Had already
restored the 2.3.6 rom by odin and
several others with cwm and not
solved.

then its a big problem

I guess its a hardware problem.. something wrong with the motherboard.. if flashing stock ROM or custom ROM didn't solve it then i guess you have to take it to the SC..

had tried this method but the efs
folder (And their archives) do not exist
in the system, unfortunately ...
I've been exploring the system files and view the log Custom recovery found the problem. Recovery was an error during the flash unfortunately could not solve the problem (yet) but anyway it was good to know where the error happened. Any help will be important, since that time my phone is just an MP3 player lol
Once again thank you and sorry for my english

Happened with me once and i think a trip to one of the samsung care center won't hurt much
Just be sure not to tell the people there that you flashed the cm7 custom rom on the device.

OK, thanks for the reply. I will try
a downgrade to Froyo in any
carrier to recover the efs and if it
fails it'll follow your advice. Thank
you very much

[Q] IMEI unrecoverably lost. EFS wiped. Help needed.

Hi everyone.
I've got to this bad situation where I wiped my IMEI. I was trying to flash CyanogenMod, and it flashed fine except that IMEI was turning into zeroes and radio did not worked. Reverting back to stock ROM helped pretty much, it worked there. So, I decided to back up EFS prior to flashing again. I did it on a rooted stock firmware using online nandroid backup from market. It told me that backup was done fine, and I did not actually check, which was a huge mistake. I reflashed CM, gapps, and then that backup. Obviously, as that backup did not really contain anything, CM did not start. Original firmware flashed by Odin starts up, however, I immediately get "blahblah.gapps failed to start", I cannot connect to wifi because I cannot enter my password for Wifi - kayboard doesn't show up (if I remove the password on router, it connects fine). If I proceed, SetupWizard just crashes.
So, without backup, the only thing I can do is possibly flash EFS from another S Advance i9070P. I know that it would contain others' IMEI, but I can swear I fist change it before flashing. Or, if anybody's willing to help, you can just replace your IMEI with something generic but recognizable, as 123456789012345 for example. I'd try to deal with it.
Or, if there's any other suggestion, I'd gladly listen.

Did you do factory reset and wipe cache? Go back to stock with flashing stock firmware. That: "blahblah.gapps failed to start" is because of wrong version of GAPPS installed.

Hey, time to rise the topic again. After I repaired my phone, after some time I decided to flash a rom for a different region, 2.3.6 also (i did not update it to 4.1.2 anymore). I used ODIN 3.07. But now it does not turn on. At all. It does not react to the power button. No vibration, nothing. No recovery mode, no odin mode. Looks like a complete brick. Why the hell is that?!
Ah, by the way, as I stated in my first post, it's NFC model. The downgrade guide was for non-NFC. So I did not have any NFC functionality after downgrade. Here I wanted to return it as well, so I used a FW for i9070P version. Never had an idea it wouldn't turn on after that.
What can I do?

is it possible???
Hi. I ve experienced the same problem, except tht I ve completely lost IMEI and baseband. Sent it for repair.the person said 1st we ll recover the baseband then IMEI would b recovered. Blv me its been 2 weeks now. I ve read every possible solution I could find but it didnt help. As far as i could understand, IMEI has to b there for baseband to recover. Tried efs pro. Tried 9 steps for IMEI recovery but nothing helped. Tried to downgrade to GB acc to the guide but repartition fails on ODIN 1.85. Used triangle away to reset counter.the counts turn 0 with device status 'samsung official' but as soon as I flash stock JB, the current binary shows custom. IMEI folder in efs is empty. Tried to do the complex methods but got scared coz rest of the fone is f9. Is it possible tht it will be repaired or not. Is there a way out?

imei deleted after kernel flash

hey guys please help me
i have note 5 n920c i tried to flash unikernel v9 on twrp
after flashing i got no reception and i lost my imei
i tried to flash back to stock rom with no result
i tried to flash the custom rom back and got noting
can you please help me and tell me what to do?

unikernel, unfortunatelly not compatible with N920C variant. This kernel for N920P... Probably your efs sector is broken.
most in case, stock firmware fixes this issue, but in your situation not!
if you have efs backup, make restore. but if doesn't, only way for special boxes from services. z3x fixes your issue, with repartition efs sector.
Only way is this i thing. Sorry !!!

z3x

first try reflashing, if that doesnt work, grab a n6 factory image and flash that.

I tried re flashing dp2
Followed by flashing factory images of marshmallow
Followed by persist fix from this link : http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576
But still no result... The phone has just gone out of warranty and cant be given for RMA..
Can efs backup of someone else be flashed as I have seen the same somewhere in Samsung galaxy forums

The OP got his phone fixed by the guarantee. I would suggest to flash stock firmware from Google's download pages. Get it back to stock and see if the problem persists.

How does the efs get deleted ?

I had an LG G2 that it happened to. Something must have went wrong during the flash. Just happened. Nothing I did wrong, just happened. Started backing up EFS after that. Backed it up during initial flash of N6, save it to Gdrive. Haven't worried about EFS since.

There are a couple of reasons for people not replying.
First of all, the lack of details on your problem makes it impossible to determine the solution.
1. What do you mean bricked? Bootloop? Stuck on OnePlus logo? Hard brick? How did you get it bricked in the first place?
2. The restore tool removes TWRP. Have you installed it again?
3. What do you mean you can't install or the update the ROM? Is there an error message? Are you trying to flash a custom ROM in the stock recovery?
4. You waited less than 2 hours. You realize there are different time zones? Some people are sleeping, others are at work.

Hey you self-entitled prick, transfer a copy of the full ROM onto your phone through adb/USB OTG/MTP and flash it through the stock recovery. If you had previously unlocked your bootloader and have TWRP installed, use that to flash instead. If you do not know what any of the above means, look for it yourself through the forums.

Reflash with the MSMtool after re-downloading everything and verifying all downloads first before proceeding. Use the tool I have posted at https://forum.xda-developers.com/oneplus-3t/how-to/guide-official-op3t-stock-reset-to-oos-t3598864
Ensure you verify before starting the flash. Also uninstall or deactivate any anti virus application installed on your PC.

should i change the data partitions and everything to f2fs or other thing. system to ext4 data to f2fs

For now, don't worry about the data partitions. As mentioned above, reflash from MSMTools, verify the downloaded package first, and then check. All your issues are probably caused by a bad file.
