i almost lost hope with poco
my imei is gone randomly after reboot and it doesnt accept sim card and wifi mac address is wiped
we don't have xiaomi shop here in my country
i have bootloader unlocked
any idea to restore it ?
If you have a funtional nandroid of your own device, you could try to restore efs partition, but be very careful, that is a dangerous operation, that can kill your device. But i dont beleive that the behaviour of your poco is caused by software/partition error, for me that sounds like hardware fault. i would send it to Xiaomi repair centre ...

First post, long time lurker, so i'll start with a big thanks to the entire community for all the help you've unknowingly given me.
I just got a nexus 5 to replace my original n5 which has a broken screen. I took a backup of the original and restored it to the new one. Unfortunately i didn't know what EFS was, so i restored the old EFS to the new phone. IMEI went to zero. HUGE BUMMER.
I was able to fix the IMEI with QPST, but the new phone will not connect to the network. I've run a check on the IMEI and it is not blacklisted. Without incriminating myself, lets just say that i'm positive that the new IMEI is good.
The phone recognizes that i've inserted a SIM but shows no signal. I've tried to search for networks, i've checked the APN settings...
I REALLY don't want to send this to LG since they can't give me a price or even a ballpark figure without me shipping them the phone...
Any advice on next steps would be greatly appreciated.
What should i try next?!
flash the factory img and do not restore your efs on it.

I guess i should have mentioned that i've flashed factory also. Currently the phone is on the latest firmware, unrooted, locked bootloader. Flashing factory had no effect at any point.
I bought this phone on Swappa BTW, so i am assuming there are no hardware issues. I'm not at all certain what else may have been screwed up by having another phone's EFS restored over this "new" phone's EFS...
More Info
I am able to attempt to manually select the network. When i search for networks, the available networks are shown, but when i try to connect it shows the Registering dialog for quite a while, then fails. This is the same behavior as a working phone without a SIM installed. The odd part is that the phone will recognize when a SIM is installed or removed. It seems that my problem may be that the SIM is not being read properly or the data is being lost/corrupted between SIM and antenna. Is this possible? Is this EFS corruption? is this something i can fix? Please help.
Bump?
So I just wanted to share my experience with you guys. I bought a used s6, and flashed a custom rom. The problem is that someone has already done the same thing without backing up the efs folder. Now I`m stuck with having an LG imei, and being unable to connect to a network. I gave the phone to a guy who will try to fix it. He said that it is quite possible that the phone is permanently dead. So keep that in mind, don`t do sh*t until you have backed up your efs folder.
edit: the phone has been partially fixed. the repair guy flashed it via z3x box, put another imei on it ( I know it`s illegal ). Now the phone connects to a network but won`t save wifi passwords ( another issue that has to do with the efs files being corrupted )
same for me, so i just switch to the xperia z5 compact, i will never go to samsung again....
i accidentally wiped the IMEI off of my nexus 5 when trying to repair my EFS partion (which was corrupt at the time), since i had the original value on a sticker on the back i tried to repair it. i finally managed to repair it by reflashing the radio image, then using the qualcom nv tools to write it back. my main problem is i cannot connect to the mobile network (which is at&t) after the repair, i reflashed the stock rom and updated it to the latest version (i used android lollipop in the repair process), then i manually set the APN settings according to at&t support page and still no luck. is there anyway to restore my mobile connection?
I have no clue if my suggestion is valid in this situation or not, but I know there are root apps and Xposed modules that can change IMEI. Perhaps you can try one of those to re-apply the IMEI to the system? Sadly I have no experience with doing this myself. Note that if you try this it will apparently erase various data.
I am aware of the xposed modules, however they are only temporary and need to be set each time you switch to a new ROM. in my case I plan to switch to Ubuntu touch or Sailfish OS when I get everything working again, which xposed does not work on. I did make a permanent change via the qualcom nv tools, but I am beginning to think I erased more than the IMEI. I know the MIED is only a few characters short of the IMEI, so thats restored, but I ended up with an ESN being written to the device even though I had not entered one. I am not sure if it was randomly generated somehow or if there is a way to figure out what the ESN should be from then IMEI. I also heard of baseband data being stored in the EFS partition, although I did flash a radio image to it prior to writing the IMEI and i think a radio image would likely have that data. I have no idea about the other types of data that a radio image wouldn't contain that would be essential to connecting. Any ideas?
So I have 2 phones (both S7e), but one lost its IMEI / having "can't mount /efs" problem. This phone unluckily doesn't have a back up of its own EFS / IMEI digitally, but it still has the phone sticker that has its associated IMEI. Now, my plan was to TWRP restore a backup from the working phone to the unusable one so that I can fix the EFS problem and right after, "edit" the IMEI number to what it's supposed to according to the sticker left on the phone.
My questions are:
1) is this possible?
2) if so, can someone help me find out the proper steps/tools to help me change the IMEI on the 2nd phone with the temporarily duplicated IMEI
3) any tips on making sure I don't have both phones running and get blacklisted for having 2 phones with the same IMEI on i was thinking just to leave both phones on airplane mode or at the very least, turn off the first phone until I get the second phone working

I think u should look for repair your efc partition
There are plenty of artical about restoring your imei or baseband version
I don't think u can restore your efc with same s7 edge backup
1st thinng u have to repair your efc partition
I have read artical about How to restore your efc partition or imei and baseband version
U will found out this thread on same page
I had also loose my efc and baseband version
But now it's fine
What i have done it's also there
My OP 8T after converted to EU and update to ColorOS 12 suddenly lost it's IMEI. I tried to rollback to OOS11 even to stock TMO but still can not fix the IMEi. Baseband is still there, device still can recognize SIM's services but no IMEI and device can't make phone calls.
It may caused because my device's EFS partitions are damaged. I tried to look everywhere to find solutions but still no luck. If anyone know any leads, please kindly help to inform.
Thanks a lot mate.

Check if you have backup of persist partition stored locally, or it has internal backup on another partition (look on partition names). Critical partitions sometimes have backups.
