Hello everyone, I am facing a problem with my galaxy i9100, can not switch the wifi on when I bought the unit was also problem with IMEI (EFS folder) then after I could hardly repair the EFS folder so recovering my IMEI, however, the wifi problem still persists.
Problem: WIFI not connecting when I try to connect the wifi icon returns to gray
What has already been done: Flash custom rom 2.3.4 Full, Full 2.3.6 and 4.0.4 complete, open the phone to see if there was BAT500 oxidized but not have on my plate, and is in great condition.
I'm currently in RootBox-JB-i9100-V4.2 / Kernel_Siyah-Dorimanx-V9.16-[21-14] - [04-05] CM-JB-AOKP-SGII-PWR-CORE
I believe it is somehow related to the EFS folder, because it was already damaged and also found some files related to WIFI inside the folder ...
Please if you can help me I will be very grateful ..
sorry my english (google translator)

Hello,
After searching about 10 pages & search engine i haven't find exactly same problem as mine but i think i'm not the only one who had this problem...
I saw that all guys having same problem as me have an IMEI problem with a file on /efs, which is not my case for the IMEI
Problem : no phone, no sms, all data is OK. is someone calls me it rings busy.
Here's what i tried
- My SIM on another S2 = everything OK, the other S2 sim on my phone gives same problem.
- Many ROMs official or non official (also a release using pit+pda+phone+csc), without solving my problem
- Using the appli GSII_Repair but i can' t download (message appears 2mins after click on install, from PC or from market)
- Phone is operator free and with no signal problem.
- At the moment i just put an official rom (nothing more) with baseband i9100xxki3, kernel 2.6.35.[email protected] #2, Version number gingerbread.xxki3. Network State=Connected, IMEI= same as behind battery, IMEISV=01
I bought the phone to someone living 150km from me and when i wanted to test it...i locked my SIM (and no puk code with me) so i bought it for not having done the 300km for nothing...and i can't use it since a week i'm trying & reading things everywhere on the net but i think here is the best place, great members, great place, and great roms i used on my HD2 before the USB connector broke. The guy to wich i bought the phone kept it a month and have no idea to what has been done the phone
So help needed....Thanks

Have you already tried to do a factory reset?
Shut down the phone, reboot into recovery mode (Volume UP + Home + Power, hold the keys until the recovery menu appears), choose factory reset and then reboot the phone.
If that does not help, you could try to flash a newer stock ROM, such as XWKJ3.
Have a look at Intratech's Official Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278
If that does not help either, it could be a hardware issue.
Hope that it is not.
Good luck !
I already have done both, and i just have done the 2 things again just in cas
Factory reset => still having problem
XWKJ3 => i'm getting permanently a message like com.android.phone crashed, i now remember why i changed for an older ROM
Sounds like flashing many roms syndrome .
Also the no no of using PIT files .
Suggestion
Download full stock rom .
Backup all data .
Go to recovery Mounts and storage Format > Cache System Data > SD Card .
No boot now clean empty phone .
Download mode and via Odin flash stock rom .
Test if still faulty return under warranty .

I dont want to be a negative ned and throw a spanner in the works here but if the IMEI is intact and the phone was bought second hand(and no offence with what im about to say) but is it possible that the IMEI has been blocked cos yourve unknowingly bought a stolen phoneIt just seems strange that only calls and sms are blocked with the IMEI no being changed.Sorry if ive miss understood the question.No offence intended.
Hello all,
I have a MID1125 (bought from france as MEMUP seller, not coby), so i upgraded from GB to ICS , the problem i have is WIFI wan't turn on.
so i'm thinking about the wifi chip is different.
i have a CWM backup, so i checked the files within /system/wifi/, it appears different to the ones from ICS.
so may be this is the reason of this issue.
then i think to put back the files from CWM backup into the new installation.
What do you think about this ?
Thank you for your help.
Hey Guys,
First time poster.. so please don't flame me...eh!..LOL
I have searched and better searched without success to my question..
I would like to revert back to JB 4.1.2 on my S3 which is SIM locked to T-Mobile UK, would I need to ROOT the phone beforehand or can I just use Odin and the relevant stock firmware.
would this affect the IMEI and the EFS folder that would make the phone unusable?.
if the procedure is straightforward would I be able to revert back to perhaps 4.1.1 (which would allow me to unlock the SIM myself..).
Hope I have made some sense with my first post..
cheers for any help guys...
4.3 changed your efs to v2. You cannot go back to 4.1.1 unless you have an efs backup from before you upgraded (an efs v1 backup).
Going back to 4.1.2 will work provided you use a firmware EMGx or later (efs v2).
Follow the guides in general stickies on how to flash stock using odin, root afterward with CF auto root.
There are many threads on efs changes, efs 'know this stuff' in particular.

Do you mean this firmware I9300XXEMG4
cheers
cancel all that... I have managed to flash my s3 with the I9300XXEMG4 firmware..... and truth be told I was crapping myself when the phone kept looping on the logo screen.... I did a factory reset and cleared the cache.....all is working.....
just a quick update...
My phone is working fine and dandy with the 4.1.2 stock firmware.... I have also discovered that the SIM is unlocked (or was not locked to begin with), tried a Tesco mobile SIM in it last night and it worked fine, was not asked to input unlocking code for it!
result all round..... :laugh:
You help me too. Thx.
So guys, please explain this to me.
After I did an update to 4.3 the efs was changed. I was ok with that, until my hard drive died and I had lost 4.1.2 backup and so, I can't restore my efs.
The problem is: Can i downgrade to I9300XXEMG4 without problems? I mean, I will not have IMEI and network signal problems? I did flashed some 4.3 roms, but I'm not satisfied with them.
after effect in this downgrading process on my s3
I have upgraded from 4.1.2 XXEMH4 to 4.3 GMJ9 VDI first. liked that very much, display battery backup[battery doctor] was on my phone but drains quickly though in reality with lag issue. i found few things in 4.3:
1. time lag,
2. emulated drive
3. IMEI shows correctly but its SW ver shows 11 instead original 01
there were dozens of good features over above these aforementioned issues.
Sometimes wanted to use Samsung's Indian keyboard, downgraded therefore back to xxemh(4.1.2)..
Problems I found,
a. IMEI shows correctly with original SW version 01 but mobile shuts down suddenly quite frequently.
b. my csc becomes unknown while typing *#1234#
c. Both USB and UART options change to modem every phone boots
d. rooted and found csc folder is missing
e. wifi gpars work but Bluetooth can not be turned ON it becomes gray . sometimes phone hangs when I try to put it ON. it restarts automatically at times.
f. phone lags just like that of 4.3
is there any method settle problems of a., c., e. and f.??

Suggest wipe phone via recovery

Boot to download mode and flash stock rom for your network .

@JJEgan, thanks for the reply and tips!
a. IMEI shows correctly with original SW version 01 but mobile shuts down suddenly quite frequently.
>>>Mobile as in what network or the phone ??
---Mobile is in Vodafone India on my I9300
b. my csc becomes unknown while typing *#1234# [SOLVED]
>. Flash the correct CSC for your network.
--CSC folder has been recovered this way in the process: re-flashed 4.3 (swc) on existing 4.1.2 (xxemh4), sw version of imei changes to version 11 however IMEI remains same, them flashed another itv (4.1.2) as explained in another thread. I lost imei as it becomes 049....
then I flashed back to my country's 4.1.2 (xxemh4). got IMEIand its sw version correctly and my CSC folder also.
EVERYTIME I FLASH I DO FACTORY RESET AND CACHE WIPE compulsorily FROM stock recovery 3(e)
--------------------------
I HAVE BEEN READING A LOT SINCE LAST FIVE DAYS, basics of flashing I guess I know as i have been doing this since 2009[Samsung Bada on GT-S6353]. I use only stock recovery and stock roms. my problems now reduce to:
1. Bluetooth non functional- can not make it ON. When I slide Bluetooth button to make it ON, phone either hangs and restarts automatically or Bluetooth button goes back original OFF position
2. phone's utilities reset to modem automatically [both UART & USB]. I check this when my s3 can not connect to pc or kies to reload my contacts on s3. This is checked by typing *#7284# and I need to set it UART => MODEM & USB => PDA. But these two setting reset to MODEM automatically whenever I check at later stage [when i found pc doesn't recognise s3].
3. phone lags just like 4.3 even in 4.1.2 [xxemh4]
I will do flashing again! Thanks once again!
=================
Flashing done! It doesn't help me
Khaaba,
When your problem solved (Bluetooth, phone lags and so on) please do post here.
I am also facing same issues.
Thanks and regards

Use this link and flash with "I9300XXEMG4_KOR_MULTI_FACTORY". That's the method I followed!
Everything is normal. Then I flashed my country's FW using Odin in PDA mode only!

AFAIK not all drivers can be modified because they are not all open source , i guess your tablet is chinease and very cheap , maybe it is just a hardware issue , do you have the same problem when you try to connect to another router (in a public place , your friend's....)? , since when did you start having this problem i mean did you already manage to connect to that same router with your tablet while being farther than 5 meters? and are your other devices connecting without problems to your router ?

AFAIK the only way to be sure if it is a software (android?) or a hardware issue is to reset your device after backing up everything (nandroid backup if rooted or something else), if the problem is still present after reseting your device i am 90% sure it is a hardware issue , in this last case you can go to your manufacturer support center or send them your device to repare it , if your device is still under wanrenty it might be free of charge , if it is a software issue , resseting your device should solve the issue but you will lose your data (if you backed up your apps on your sd or on the cloud it will be easy to get them back) , to reset your device if you are rooted (after backing up everything) go to your custom recovery (twrp , clockworkmod...) and then go to factory reset (or something like that :silly: ) and select the only "yes" option that you will see in the screen , if you are not rooted (stock rom) you normally will find an option for resetting on system settings/personal/backup and reset (i am on cm9 it might be different for you but just look for reset option in settings you might be asked for your gmail account to be sure you are the owner of the device) , normally resetting is a natural process but i am not responsible for any damage that might happen to your device (be careful with cwm and BACK UP everything)
So I have had been jumping Custom ROMs lately, and after a couple of ROMs I had tried my phone stopped connecting to WiFi(it works fine for Cellular networks)! So I came back to CM11 (May 24 nightly build) and the wifi still didn't work!
Now, I thought this might be a modem issue so I installed Perkas File Stash but I don't know which modem to install..
I however downloaded the latest one(the last one) xxemg4.zip and flashed it and now my phone connects to WiFi but only if I keep it on top of my router with open WiFi
It would great if anybody could help!
ps: I have a i9300 with
FCC Id: A3LGTI9300A
SSN: I9300GSMH
BASEBAND: I9300XXEMG4 (After Flashing)
ps: I know questions similar to this have been asked before, but none of the solution work including:
Reverting back to official ROM
Using 91WiFiFix
Changing Baseband as mentioned above
Editing wpa_supplicant.conf (Adding #pf = 1, fast_reauth=1, deleting all configured APs)
Making my Wifi work on different channel, mode, Band, encryption etc. etc.
Here is my bugreport and logcat:
Probably failure of the aerial module or motherboard issue.
Any news about this?
I got the same issue today.
It says it's connected to the Wifi, but it can't really use the Internet for anything.
All other devices work just fine with the Wifi connection...
EDIT: it's something weird with the router. For some reason, it has this behavior for Samsung devices, but not for anything else.
