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 PLEASE!! Strange issue, moto x XT1056 Sim not working

model written on back fine print: xt1056
firmware when i got this phone from ebay: xt1053 retail LP
Bootloader version: 30.BE
i checked imei by dialing *#06# and it showed 0 as IMEI number. i inserted sim and it worked, i even changed sims from different networks and they worked.
everything was ok, but i wanted to fix this imei thing, and downloaded qualcomm nv tools and then read items, and it showed ESN and MEID items correctly but IMEI was 000000000000000000.
i put IMEI similar to MEID with adding 9 at the end for make it 15 digits. wrote it successfully into nv items. rebooted phone and whoaaaa.. IMEI got changed.
later on i flashed xt1056 lollipop stock rom, IMEI was removed, dont know how. and since then no sim is working, no signal, nothing. checked with nv tools, tried to read IMEI and it is shown as 00000000000000.
i cant change them now, it gives read only error even when it accepts SPC code and unlocks phone successfully.
please help, my phone is useless right now.
strange is this phone allows any rom to be flashed on it regardless of carrier specific.

Help ! Imei and Serial number corrupted G620S-L01

Hello everyone
I don't know if this is the right place to post it but I have a problem with my Huawei G620S-L01
I got it from a friend with Stock Rom 4.4.4. Everything was fine for 2 months until it starts bootlooping. I never tried to root this or something like that... After googling a bit, I found the solution to the bootloop in flashing Stock Rom via Sdcard/dload method. Everything was fine again... Then I noticed that the Lineage 14 (7.1.2) was out and I wanted to get it. But in order to flash it, I had to unlock the bootloader and flash a custom recovery. It wasn't a problem for me since I've already done it with other phones. The problem was to get the bootloader code from Huawei because I noticed that my IMEI changed and my Serial Number changed and shrinked ..... so I used those who are on the battery to obtain a bootloader code from Huawei (because the corrupted ones doesn't exist in the IMEI database even if they seems to be real). I thought that will finally work.... But no, the fastboot command to unlock the bootloader says : FAILED (remote: invalid key, unlock fail)...
So this is where I'm stucked. What should I do ? Did I flash the wrong firmware at the first time even if it seems to work like a charm?How can I get my IMEI and S/N back ? Does flashing another stock firmware will help me? please help me :crying:
I'm still unrooted
Thanks in advance
Please help me ! Anyone... :crying:
It seems that there is no solution...
