I have this same issue. Creating the keystr file doesn't seem to be working for me either. I have the same symptoms as others, upon reboot the file is gone, bluetooth is enabled and screen timeout time is set to 10m.

This is beyond frustrating. Also like others I already tried reseting to stock using ODIN (before reading this thread).

Any thoughts or something else to try?

Thanks guys.
[T-Mobile Samsung Galaxy S II SGH-T989] deadbeatcocoa:
Yeah same here! Also, I would add that my phone works fine besides that. It's only frustrating that I don't have access to Power menu and stock lockscreen and knowing something is wrong with the phone.

I saw other people mention that when they received updates with Kies, it resolves the problem by itself. But since Telus didn't released a 2.3.6 update, I think I have to wait for ICS to be released for SGH-T959D. Might as well wait for Dr. Dre to release DETOX :p

lockscreen fix

Link for efs files is down..you can also save the efs files from eb's cyanogen mod 7 which has the lockscreen files and save them..copy and paste to internal storage efs folder ..then reboot!

This worked for me...thanks a million, I was worried that I may need to return the s2 I just purchased off eBay..

OP it would be a good idea to add this the first post itself. I did copy the keystr file to efs/imei however it did me no good...maybe the issue comes up for different people for different reasons...this could be one of them :)
[T-Mobile Samsung Galaxy S II SGH-T989] brambi42:
I have the same problem, I have tried with the termonal emulator but nothing, the file in efs/imei is ok and in ON.

All work with the aopk rom, but when I change, for example MIUI, nothing, dont work a power menu and lock screen...

Please help me.

Tks
[T-Mobile Samsung Galaxy S II SGH-T989] quincyfbaby420:
U still may be missing a file in your efs folder..any custom rom with a working lockscreen efs folder just needs to be copied and replaced in your efs folder..worked for me I lost my lockscreen by turning off the lockscreen toogle than I flashed another custom rom before I turned it back on...the only thing that worked for me was to copy efs folder from eugens cm7 and add to your efs folder using root explorer

ics black edition custom rom r4 which I'm currently on and everything works great ...its easy
[T-Mobile Samsung Galaxy S II SGH-T989] MARINERMOOSE241:
Could you post a link to this rom that contains an efs folder? Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] deadbeatcocoa:
Figured out the problem!

I figured out my problem! Appears that when I was creating the keystr file, I added the extension .txt ...

So here is the solution that have been posted on other threads

i actually figured out a way to restore my lock screen back.

Note: This involves messing with the efs folder. So do this at you own risk

also, your phone must be rooted in order to do this.

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.

[T-Mobile Samsung Galaxy S II SGH-T989] MARINERMOOSE241:
This works but didn't survive a reboot. keystr file gets deleted upon reboot. Anyone know how to keep it persistent?
[T-Mobile Samsung Galaxy S II SGH-T989] deadbeatcocoa:
If you keep a copy of keystr on your sd card, it shouldn't be too hard to paste it whenever you're booting. I know that it's not the best solution but it should do it.

If you're on T-Mobile, I would suggest you to flash the original 2.3.5 software through odin and then upgrade your phone through KIES. Some people mentioned that it restored the properly efs folder on their phone.

I'm on Telus in Quebec, Canada and they didn't release 2.3.6. So I'll have to wait the official ICS update if there isn't any solution posted.
[T-Mobile Samsung Galaxy S II SGH-T989] MARINERMOOSE241:
I do keep a copy on my SD card it's just a minor pain in the ass. I am on T-Mobile and downgraded to stock 2.3.5 went through the upgrade to 2.3.6 though KIES but it didn't help.

How I fix the problem,

I had this problem for long time, and I could not figure out how to fix it, Many thanks to guys who gave the hint, and direction to fix it.

Step A, B can be done on any level , meaning at your current rom with root/ superuser

Try may be it will work.

Pre - requirement: ROOT and Superuser

Step A:

A-1:	Download “920 Text Editor” from the Google play

https://play.google.com/store/apps/details?id=com.jecelyin.editor&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5qZWNlbHlpbi5lZGl0b3IiXQ

A-2:	Download “root browser lite” or any root explorer

https://play.google.com/store/apps/details?id=com.jrummy.root.browserfree&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5qcnVtbXkucm9vdC5icm93c2VyZnJlZSJd

A-3 Download Any Hex Editor

Step: B

B-1	Open 920 Text editor Type “ON” and save as “ keystr” in SDCARD or anywhere you can remember.

B-2	open saved “keystr” in hex editor

B-3	Make sure in first line 4F and 4E is there, and then close the editor.

B-4	open Root browser lite, locate the “keystr” file in your SDcard, and copy it to

/efs/imei/

For copying this file in your main memory you need superuser access.

Note: if in “efs” folder you don’t see “imei” folder just create one.

Then copy the file in it “keystr”.

Now how I fix this bug:

Step 1: reinstall the stock rom 2.3.5 using ODIN;

1.1: need to install CMW and Superuser (if you dint install yet)

Try step A and B it should work; and reboot you device to see if file don’t delete. (Some user complaint files “keystr’ get delete once you reboot, though my dint deleted)

Note: make sure to change the setting of screen lock time to “immediate”

Step 2: Install stock rom 2.3.6 using ODIN

Check power button, and screen lock is working

Step 3: Install custom rom

In my case I install RomChicago - ChicagoFire [ULCD2][skinny] 4.20.12

Since the skyrocket and t989 are so similar, many of you are still, aving issues with the above solution, or one in the open, because the fix won't stick. This indicates a corrupt efs partition. If any soul is brave enough to flash the fix here:

F.A.Q.

(1) Will this ROM work on the Exhibit 2 4G?

A: No idea. Ask the devs for the Exhibit 2. The hardware is quite similar but some things do differ.

(2) Is this CM7?

A: No, it is not. I'll get on that when I can.

(3) What are the advantages of this ROM over stock?

A: It is rooted and much faster. Try it out yourself. :P

(4) What are the surprises you were talking about?

A: Unfortunately they couldn't be released at the same time as this ROM, so you'll just have to wait.

(5) Will you update this further?

A: As of V3, I dunno. I pretty much done everything I had to do to make it work as powerfully as possible.

(6) Is this overclockable?

A: It is as of V3, download the OC Rom.

Now that the phone reads the external sd as the internal memory, I can finally see some use for the 16gb micro sd I was given for Xmas.

But I do want to keep all the data I already have on the one I was using up to now, so if I transfer the whole card on my PC and then on the other (bigger) card and finally put it in the phone, will I have all my data or will I be missing something because they are hidden Android system files?

The most easiest way is using the app Root Explorer (or other file-explorer app with root capabilities).

* Browse to the folder /system/csc

* copy the folder /system/csc to your "sd-card" --> /sdcard (the folder contains mostly 3-letter folders)

* Exit root app and plug your Tab to your pc.

* Copy it your pc and zip :).

I can still access the original stock rom, if I nandroid back to stock.

But before I do I like to know what are these csc files and are those of my P7510 similar on the P7500?
[Galaxy Tab 10.1 Q&A, Help & Troubleshooting] joramteusink:
I checked the firmware code of the P7510 in a shop, but that wasn't the same.

Perhaps the CSC code is. CSC stands for Country Sales Code. You can see it by installing the app "SGS CSC Selector" or "Samsung Galaxy S / S2 CSC". The selected CSC code is then shown. DONT change it, as it will wipe your tablet to factory defaults.

Edit:

App "Samsung Galaxy S / S2 CSC" works for sure. You can safely click the first button.

It is also possible to open the folder /system/csc/customer.xml.

Line 5 and 6 describes the selected Sales code.

I finally restored my official ROM (Honeycomb 3.2) with correct CSC code. Still can't use Kies upgrades, but hey...that's whats Odin for. This is how.

Go to:

http://www.sammobile.com/firmware/?page=3&t=3&o=1&m=GT-P7500&r=1#regiona

Download:

P7500XWKL1 ##	2011 December	P7500XEUKL1	Europe

--------

(Or use client from http://fus.nanzen.se/ and select

- Firmware: Android - GT-P7500 - Europe

It shows now:

- Product code: GT-P7500UWDXEU

- PDA: P7500XWKHD

- CDC: P7500XEUKH3

- Phone: P7500XWKG1

Check your firmware and download.

But it is the exact same firmware as from the other website and that one is easier to flash (I guess) through Odin.

--------

* When you have downloaded the Zip-file, extract it.

* Please clear and wipe data and cache and do factory defaults.

* Boot your Tab in Odin mode.

* In odin select your downloaded firmware in Boatloader, PDA and CSC (leave Phone) blank. And click start.

* After a while it reboots (if it bootloops, then clear data and cache partitions again).

When you start your tab you'll have the official ROM version for The Netherlands active. And in my case, the Dutch CSC code PHN. Finally! :)

Edit:

* And then install all your apps and stuff...grmbl :D

I'm trying to follow the instructions for using alternate keyboards. However, I don't know where to put the anycut APK. When I look at my NT on my PC, I don't see a lot of files I know are on there. I'm only seeing that 1GB of space, and whatever's on my SD card. For instance, there's an image I'd like to use for wallpaper, and I'd like to move it from where it is to the wallpapers folder, but can't see any pictures in that 1 GB of space.

So, two questions:

1. Where do I put APKs, and how do they get installed? (Okay, so that's two questions.)

2. How do I get access to the files on the rest of my NT?

Thanks! And yes, I am searching through the forums to find this.

UPDATE: Okay, figured out how to get to the root of my NT, using ESFileExplorer and eventually getting to the point where I gave it root permissions. And from there was able to find the anycut APK and install it. If anyone can answer the second question, when viewing files on my PC, that would be awesome.
