HELP!!!
After i tried using App2sd on my rooted S3 I9300 (Intl version), my phne went into a boot loop, and apparently i tried fixing it by installing a new rom..now, here comes the real problem..I installed a wrong ROM, it seems (although the rom is for i9300, it is for a different region)..
So after installing this Rom using odin, i get the message "e: failed to mount efs folder"..
Now im lost, especially because i have no backup of any kind...Is my efs folder corrupted??? and the phone still wont go past the samsung logo..only hope i have is that i can enter into recovery mode
Any suggestions ??? Please..anything...

sent from the state where marijuana is NOT illegal !
it started when i was using offical firmware jelly bean 4.1.2 (I9100XXMS1) rooted and i wanted to flash Cyanogenmod 11
to do so you need CWM recovery 6.0.4.4 at least but i had philz touch cwm based 5.0.x.x. (that kind of cwm i had with root)
so i downloaded CWM recovery 6.0.4.4, copied it to my sd card, entered recovery mod and flashed that CWM recovery 6.0.4.4..
so if im not wrong i flashed different version CWM recovery that i had..
because of it bootloop started.
somehow i managed to restore my phone back to working status. i had a lot of problems like "cant mount E:/ efs" and bootloop all the time but now almost all is ok
almost except IMEI...
i used some SGII_repair app so now i have signal but my IMEI is different than before.. no idea how to restore it.. why i need it? cause i cant enter my sim contatcs
and no i did not backed up my /efs folder before so i cant just copy nv_data.bin, nv_data.bin.md5
no idea what to do now.. i checked every topic about it and still dont know how to fix it
help..
No IMEI & no EFS backup = service centre or local mobile repair shop.
but according to that [GUIDE] Recover your IMEI in 9 steps.
i dont need imei or efs backup.. i did same as on guide and it did not worked.. still IMEI changed to 004999010640000
Exactly my point
well at least phone is working..
i can call and ppl can call me..
but its not my IMEI so its not good..
if they can do it at service centre or local mobile repair shop i cant do it myself?
galaxy s2 9100 e:failed to mound/efs
this is one of my friend mobile
when he give me this its working but no imei with 4.0.3
then i tried to update to 4.1.2 after that it just rebooting
then am all most read and try all threats about this prob but still it unfixed
i tried all most all the way to get efs. i have no backup of that. can i manually write down that? bcz before i get an lenovo like this then i just manually enter the imei with mtk droid tools
now the condition is:-
cwm mode with cyanogenmod 4.4.2 rom boot loop
model GT-I9100
What have you tried? Bootloop...system,data,preload,cache format then flash the rom/gapps this should make it boot up ok. Is imei blocked? Have you asked you're friend? Sounds like it to me

Change thread name for correct or you probably won't get any help.
Hello,
I have ran into a problem. I am using Symphony Xplorer W69Q and I was looking for a custom ROM. I was liking mostly MIUI. So I have contacted them and asked if there has any Custom ROM for my device. They told me that there has not any ROM for my device. So I have searched on google for any other custom rom and get one of MIUI 7-
So I have decided to make a try.
One I have collected Philz touch recovery and flashed the ROM, I have lost my IMEI. I didn't take a backup of my current ROM too. Finally I have no way to get SIM card working as they are no longer being detected.
I think I made the mistake by wiping the cache and also dalvik cache as per their silly instruction. I have installed the ROM successfully and there have not any other bug except the SIM card/IMEI error.
When I press *#06#, I get-
IMEI1- Invalid
IMEI2- Invalid.
Then I flashed the following Stock ROM using SP Flash Tool
(Symphony_W69Q_1_FL_V03.0_V1.0)
But still I can't get RID of the Invalid IMEI problem.
I also tried to use the SN writer tool. But I couldn't find the database file listed here
androidmtk[dot]com/use-sn-write-tool
(I couldn't get any file of MDI_DB and AP_DB in my stock ROM)
Also tried this tutorial
on Youtube-
Android phone invalid imei repair
by Azeem Md
But it not also worked for me. I couldn't find the database file for my Phone.
So I am still stacked on Invalid IMEI problem. I also tried Chamelephon.apk and Engineering mode in MIUI 7. But there the CDC Information can't be selected because it is grey there.
So is my phone dead now????.
Please anyone help me by providing me a working solution with necessary file download link.
Have you tried this? There are video tutorials too.
