I updated via Kies to version 4.0.3 and now I have no lock screen. I've tried using slide, face, pattern and pin but when I wake my phone it goes straight to the home screen. Holding the power button also doesn't bring up the power options .eg. flight mode, power off and silent, it just turns the phones straight off. I asked Samsung about it and they just said sorry try doing a factory reset, I did and it didn't help. I used odin and went back to stock 2.3.4 (the lock screen worked fine on this version) and then updated again but I still have the same problem.
Country - United Kingdom
Phone - Unlocked
Model - GT-I900
Baseband version - I9100XXLPS
Kernel Version - 3.0.15-I9100XWLP7-CL340913
Build number - IML74K.XWLP7
Any help would be much appreciated.
Thank you
do *2767*3855# couple times, if that doesnt fix, use odin to flash. and after flash do the code once more.

Sounds like you are either missing your /efs/imei/keystr file, or it is corrupt, or has the wrong setting in it.
Google this: "site:forum.xda-developers.com i9100 ics no lock screen keystr"
You will need root to apply the fix you find. If you don't want to root, you will have to go back to Gingerbread.

-Exact model phone? (e.g. GT-I9100, or GT-I9100G?)
-"ics 4.0.3 any firmware" means what? Which ones have you tried?
-Did you try the OFFICIAL RELEASE 4.0.3 version? (i.e. through Kies?) I mean you could have been trying one of the leaks, which were known to have bugs.
i have gt-i9100, i tried leaked 4.0.3 europe I9100XXLPH_I9100OXALPH_OXA I9100XXLP2_I9100OXALP2_OXA and today i flashed it with I9100XXLPQ_I9100OXALPQ_XEO_2 4.0.3 official andi flashed it with odin
my handset directly shutdown when ever i press power button, no flight mode and no other option comes
Reads like a wrong firmware flashed .

Take a look at this.
EDIT: the thread linked only talks about the lock screen, but this reportedly also fixes the missing options on a long press of the power button.
problem solved as ctomgee mention
thanks
For ALL whoever are facing problems with the LOCK SCREEN here is the solution :
Tools Needed:
1. Hex Editor
2. Root Explorer
Steps to restore:
1. Using root explorer locate the /efs/imei/ folder. In that folder there should be a file called keystr. In my case the file was missing which is why the lock screen was missing and was causing my problems.
2. using root explorer create a new file called keystr
3. also in root explorer open the file keystr in text editor and type ON
4. now go into hex editor and locate the /efs/imei/keystr file.
5. using hex editor the first two values in green should be 4f and 4e. all others should be 00.
6. make sure you save the file.
7. reboot.
Press Thanks, if it helps you...
Hey I'm having a somewhat similar issue... I was trying to update to the latest cm9 and a different kernel codeworkx made and in the process the kernel instal failed... right after that my power button stopped responding completely... and now it.seems.to.be responding buy not always... seems.to maybe be a hardware problem but I'm.not sure... because the issue started right after this bad instal... maybe its my imagination. But feels like when pressed at a certain angle it works... :-|
Anyway I was trying this method to see if it helps but my hex editor doesn't show me anything inside the efs folder to be able.to.edit it... with root explorer I see two ketstr files... one is just keystr... the other is keystr.bak... should I only have one file or what may be the issue here...?? Both of them are set to on tho... :-|
Any help will be highly appreciated since I really don't want to need to repair the button since there is no warranty on this...

Samsung S2 Screen lock and Flight mode not working
Hello
today i upgrade my Samsung S2 from 2.3.6 to ICS 4.0.3 with the help of ODIN
Details
Phone Brand: Samsung
Phone Model: GT-I9100
Build Date: 03/04/2012
Android Version: 4.0.3
Type: Unbranded
PDA: XWLP7
PHONE (Modem): DDLPA
CSC: ODDLP9
File Name: GT-I9100_INU_I9100XWLP7_I9100ODDLP9_I9100DDLPA.7z
After successfully upgrade i am not getting the option of flight mode after pressing the power button for a long time( my phone simple restart) also screen lock is not working in my phone.
I tried to check the file under /efs..but this directory is empty in my phone,
Can you help me in resolving this problem.
The answer is already in the thread. You'll probably need to be rooted to do the fix.

First off; are you rooted? If not, you need to root first. Then try the fix linked above.
Edit: oops... didn't see oinky's post.
Hi,
Originally my phone was from the UK Carphone Warehouse (CPW)
I have upgraded it from 2.2 to 2.3 etc...
The last time I did a firmware upgrade to ICS was a few months back and I didn't have any problem doing it.
After the upgrade, I had a few bugs. I used this file - GT-I9100_XEO_I9100XXLPW_I9100OXALPW_I9100XXLPW.tar and the main bugs I have are - The screen won't lock and when I press the Power Button, it will turn the screen off but when I hold it for 1 second the phone closes down.
So today I thought, lets see if I can change my firmware to a CPW version, so I downloaded GT-I9100_XEU_I9100XWLP7_I9100XXLPS_I9100XEULP5.tar and installed that. It went through the usual stuff and upon restarting I was getting an "android.core" crash. The screen stops working and after several reboots nothing change. I also booted up and cleared the cache, and this didn't do anything either.
I have just reverted back to the first ICS upgrade but still has not screen lock or when I press the power button for 1 second it closes down.
I wondered if anyone else has had these problems or could recommend to me what may fix it.
I appreciate all help
Thanks

You're in the wrong section, this has nothing to do with development
Sent from my SGH-I777 using Tapatalk 2
First of all wrong section mate... By the way u hav written it seems that u hav not wiping the DATA or factory reset after every flash. Try wiping DATA before and after flashing.. Also wipe cache..
Hi and expect anybody could help me. I recently updated my GT-I9100 by Kies to Android 4.0.3, but that was not working fine. I wipe de cache and reset to factory, but my problem was the same:
I can't lock the phone by any means, is not wotking PIN, Patron, Face, even the slide, I can config but doesn't works. And one thing more, If I push the power button by one sec to show the Options menu (where you sould activate silence mode, plane mode, restart, activate data or power off the phone), the phone is turn off inmediatelly.
I back by a ROM to Android 2.3.4 and works fine, the I installed another ROMs (even one to 4.0.4) and the previos problem is allways the same.
What can I do?, Some body could help me?.:good:
Thanks in advance.
Search for keystr along with whatever other terms you've already been using.
Hi
I have a 4.0.3 france firmware installed samsung I9100G.But lately the no lockscreen problem (holding the power button will not bring the options and just shuts the phone off),ringtone and a few other problems started to annoy me really bad.
I'm thinking to install the 4.0.4 german firmware from samfirmware but how stable is it? is there any problem with the 4.0.4 or anything special i should know about it?
i have reflashed the 4.0.3 but those problems didnt go away.
thanks for any helps.
Go back to GB.For me that is more stable than ICS or JB.

If the firmware is official, it should be stable. So, your choice: or GB, or ICS.

updated to 4.0.4 but nothing changed.
ok here are the problems:
- The power button options are not showing up. if i hold the power button it just closes the phone directly.
- The screen lock doesnt work. Wont lock the screen with any option there.
- The sim lock doesnt work. If i put the sim lock on (put a lock on the sim) the phone starts normally but wont let me call or text. So i have to disable the lock on the sim to make it work normal.
Now these are the problems i have seen so far. When i got the phone it was GB and there was absolutely no prob until updating to ICS. So whats the suggestion, should i give a try on custom firmware ICS or go back to official GB? if you say custom firmware then which one?

It's always recommended to perform a factory reset after upgrading your phone software

For me the samsung stock roms are like windows o/s.
GB=xp
Ics=vista
Jb=w7
A crude comparison......but vista was a pile of crap.....

1. If your phone is not rooted, root.
2. Create file /efs/imei/keystr, containing the word ON.
3. Make sure the file has rw-r--r--, or 644 permissions.
4. ...
5. Profit!

ok thank you very much bro. that did it
i first rooted the phone from here: http://forum.xda-developers.com/showthread.php?t=1679778 with the option 2.
then used this little guide:
- Download "Terminal Emulator" app from market
- open it
- type into the command:
su
echo -n ON > /efs/imei/keystr
sync
Go to home, force close your terminal app, shut your screen off, and when your turn it back on your lock screen should? be there.
Obviously you must be rooted the "su" command
And for Signal Problem Simply do not put any pin on your sim ,,,
I hope someone has some experience of this problem, I will do my best to explain in some detail.
It is as out of the box currently running version 4.0.4 firmware.
The history, initially stock firmware version 4.0.3 was running, the USB was a little loose, so I swapped the complete pcb with another S2 I have with a faulty display, to make things a bit more complicated I also put in a 2Gb SD card, when I rebooted the problem appeared, on pressing the power button to wake up, the screen comes on to the lock screen in dimmed mode, and it will stay like it for anything from 5 to 15 seconds, then the screen will go to full brilliance and the screen can be unlocked.
What I have tried, removed and rebooted with sd card removed, swapped back the original USB pcb, and swapped back again as the problem remained, also upgraded to firmware version 4.0.4, that is more or less where I am now, the problem remains.
Have tried researching but unable to find anything relating to this problem, do you have any ideas?
Update:
After further reading, it appears the original firmware may have been customised, because I was not able to get Kies to connect with the device and the CSC was stated as 'unknown', which from what I have read indicates a custom ROM.
Having flashed the stock firmware , on the recovery menu I get still the message #Manual Mode# Appling Multi CSC.... Applied the CSC code: XEU Successfully applied multi CSC, which was also present with original firmware but it never actually applied the code as it stated CSC 'unknown'. but I can now connect with Kies and the CSC code is stated as I9100XEULPA.
Is it normal to get this message at the recovery menu?
Is it a symptom of the same lock screen delay issue?
Solved
I spent 6 weeks trying to fix this, the most aggravating of problems are sometimes very easy to cure when you know the answer!
Disable auto brightness, easy, your long wake up delay has now gone.
Let me know if it helped you.:good:
