Upgrading to Froyo 2nd handset

Afternoon All,
I am lucky enough to have two handsets i9000 international versions locked to Bouygues Telecom, France.
When I received the first handset I quickly upgraded it to JPK without reading the forums and therefore I was unable to unlock it. Also I deleted all the contents from the efs folder thinking that it would regenerate the contents on reboot (stupid me).
Now I have received my second handset I have kept it on stock 2.1 and have successfully unlocked it using the sgs unlock apk available on the market.
Is there anyway i can use the intact efs folder on my second handset and transfer it to my first handset ?? If this is possible does this mean that both handsets would have the same imei ?? is it possible then to change the imei to the imei that it came with when i first got it ?

Help unlocked phone now it wont read any simcards

Hi
I unlocked my phone today using a hack method, it worked but the IMEI had changed, I had backed up my original nv_data.bin file so put that back over to the phone. The IMEI is now correct but when I put any sim card into the phone and try to unlock it doesnt work. I did *#7465625# to check the lock status but it does not say ON or OFF for anything, it is all blank. Have a bricked my phone? Hope someone can help.
Its ok all now fixed thanks another section on this forum. Thanks Guys.

Restore TA Partition

Hello so i unlocked the bootloader and checked the bootloader status which was unlocked but before doing it i backed up ta partition of my device. And to test it i restored it and checked again and it was showing bootloader unlocked allowed yes.
So I went ahead and unlocked the bootloader again tried many custom roms in a year.
Now after a year I am trying to restore TA partition with the help of backup ta tool but somehow I am getting error in restoring it.
So all i am asking is there any manual way to do it except for the software??

Tell us which error you are getting?
Are you already back on stock?
My feelings are that maybe you need to be on stock bootloader or kernel to restore your ta partition.
How you searched the TA thread for a solution?

Recover IMEI?

Well I have been modding phones for a while, and I've been able to avoid anything this catastrophic so far, but yesterday while using Qfil, I clicked on erase entire flash.
So far I have recovered everything except my IMEI so my phone is not connected to my network. My question is can anyone help recover or restore my IMEI to my ATT Locked LG V40 with unlocked BL and Unlocked Rom?

probably my guess is a no, you can get those back by flashing a kdz or using qfil unbrick method see if they restore imei

Not long enough obviously, one of the first things suggested before flashing anything is to backup the IMEI partition, EFS for Samsung, to avoid having an expensive paper weight like the one in front of you..
Might need to find someone with a box now.

Really I've never heard that before...I only backup what's tickable in TWRP .-. I think IMEI might be one of those options...
