Hello all
First of all thanks for all the excellent work.
I posted this in another thread which I probably shouldn't have done in the first place, I did find a solution to my problem and I thought I would share it here.
I went (the Odin way) from laggy 2.2.1 to battery hungry 2.3.3 then to 2.3.6 which works very well.
I then installed the CWM root + recovery kernel by Chainfire.
However I then realised my phone was in KOR CSC.
After resetting it to XEU (using the USSD code method) the PIN lock screen disappeared completely and even if I set a new code the phone would never ask for it! The same applied to Password Lock.
(Pattern Lock worked but somehow it feels unsafer to me (even if I know that by deleting password.key anyone can gain access anyway).
I tried restoring from a previous Clockworkmod backup which had been made whilst PIN lock screen was functional, but it didn't work.
I then tried wiping the phone (except for internal SD) using CWM Recovery and then restoring from the CWM backup. It didn't work either - PIN lock screen was still not working.
Problem seemed to lie in the fact that I installed CWM (together with rooted kernel) *before* changing CSC from KOR to XEU.
When the stock recovery tried to wipe the phone, it failed.
I think that's what messed up the phone when it comes to the PIN lock screen.
So making sure that I had already a copy of the /efs folder safely stored in the internal SD and somewhere else, I overwrote /efs with the backup copy I had, and the phone went back to KOR CSC... plus a fully functional PIN lock screen!
Unsure as to how to proceed, but feeling safe now I had (more or less) safely tinkered around with /efs, I finally decided to delete the /efs folder and then change CSC.
The phone rebooted into stock recovery, tried to wipe memory and it failed, then rebooted, and voila, a new /efs folder had been created, albeit with a "generic" (and probably unusable) IMEI! Everything was working though, including the cellular data connection (I didn't check whether it was able to transfer any data but the icon and light up arrows did show up). And PIN lock screen was functional too.
I then replaced /efs with my backup copy (with ES File Explorer, rooted) and rebooted the phone.
My beloved phone then went back to my good old IMEI, kept the new CSC (CPW in this case, which is UK as well so it suits me) and PIN lock screen functionality!
So 'next time' I would follow the procedure below:
1. Flash 2.3.6 ROM
2. Change KOR CSC to XEU (or CPW for Carphone Warehouse) using USSD code command
3. Phone will restart and should wipe memory fully with its stock recovery.
4. Only then flash Chainfire kernel ROM which roots 2.3.6 and installs CWM Recovery.
I hope I haven't made any big mistakes along the way and that this humble contribution can help someone, other people's contributions have helped me a lot.
Cheers

PIN screen lock not working after CSC changed from KOR to XEU
Hello all
First of all thanks for the excellent work, I went from laggy 2.2.1 to battery hungry 2.3.3 then to 2.3.6 which works very well.
However it came with the KOR CSC.
After resetting it to XEU the PIN lock screen disappeared completely and even if I set a new code the phone will never ask for it!
The same applies to Password Lock.
However Pattern Lock works.
My phone is rooted and has CWM Recovery.
Thanks so much in advance for any insight!

Hey all,
I'm stuck, at a loss here...
I have a galaxy S4 GT-i9500 and am now stuck unable to boot up through my encrypted phone password. Here's what happened in choronological order:
Encrypted the phone (My unlock PIN = "0000")
Installed cofface cwm recovery
Rooted the phone with cwm superSU v0.99
Backed up with external SD
Flashed pacman i9500 4.3
Rebooted and... it said something along the lines of "encrypted phone, needs to be reset" and it wouldn't start up, it only gave me the option of "reset phone" and it would just reboot it.
So I decided to attempt to restore my backup. It said "wrong MD5" so I took out the sd card, popped it into my computer, and was told to just have a blank nandroid.md5 file in the backup and it should work. It did.
So my backup restore is totally successful, but now when I turn on the phone and have to enter the PIN, my PIN is WRONG! I can't get into the phone now because the PIN doesn't work.
I really don't care about my backup datafiles, I don't care if the phone is encrypted, I just want a working phone again with whatever ROM is available. Can anyone shed some light on my situation? I really don't want to drop another $600 for a new phone.
Thanks
Hi, i have problem after debranding my galaxy.
Wifi is not turning on, and i can't call, when i try, there is a black screen.
I have branded PL in "Plus", and i tried with xeo roms from april (I9505XXUAMDE) and may (I9505XXUAME2) and modems for them.
When i tried first time to change rom, i had error in odin (can't write or something like that). So i rooted my device using cf-auto-root, changed csc from btu to xeo, then I9505_OFFICIAL_STATUS_MOD, wipe and triangle away, then rom.
How i can fix that?

If I be you - i try to go to Advanced phills touch recovery menu, format there everything (system, data, partitions EVERYTHING) except sd card. Then i would like to try to flash Android OS (4.3) with repartition (pit file if I remember it correctly). After that, the good idea is install root, than phills touch again (I don't remember, but something overrides another one and recovery menu dissapears or...whatever, need to try) and test again if you have this issue.
Giving this information you gave, it's even for SUPER DUPER PRO EXTRA HIGH-RANKING with IQ over 9000 developer is actually impossible. Anyway, I'e just told you the best way how to fix it.
I found somewhere similar problem, and i tried to install 4.3 rom, and everything works fine
Hey guys quick question before I download and attempt it, I have an Australian i9506 (Cat 4 LTE) but we don't have an official 5.0.1 firmware yet.
Can I just download the Nordic version from http://www.sammobile.com/firmwares/database/GT-I9506/ and install it, or would it brick my phone/radios not work?
Thanks

Hi mate,
Yes you can !! it will not brick it , you may have (or not) problems with the modem as maybe is not the best for your region but you can always flash another...
should not be a problem
BACKUP first , nandroid and your EFS Folder, just in case there is a problem
Just to add to the previous suggestion, use Wanam's EFS Backup Tool rather than Samsung Tool, as it not only backs up the EFS partition but the hidden partitions where the IMEI and the modem are stored.

+1 mate!!
It also depends if your phone is carrier locked.
Thanks for the advice guys I'm giving it a try now, will edit as I go. My phone is not carrier locked (Voda AU don't lock them fortunately but they provide the codes on their website for free to unlock anyway).
So I downloaded Odin3 3.09 and the firmware I9506XXUDOA6_I9506NEEDOA6_NEE (this is the link from sammobile).
I'm following the instructions I found on another site but it's basically put the phone into download mode (home, power and volume down), agree to enter download mode, in Odin for AP select the .tar.md5, make sure Auto Reboot and F. Time Reset are ticked but not Re-Partition or anything else and start.
EDIT 1: The phone rebooted into recovery and updated something, now the phone is booting with a new boot animation. (for those referring to this I was on the latest AU Voda FW, then updated to CM12 5.0.2).
EDIT 2: After the usual nerve-wracking amount of time of first boot the boot logo finally went away and the usual "optimizing apps" message has come up and it's started (235 apps whoa the bloat). Waiting for that but at least it's working to a point where I can recover it. I just realised it's 6:10AM now and I FORGOT TO MAKE A BACK UP. I hope this works but worse case scenario there's a 4.4.2 Vodafone firmware I could flash and try my luck with if this doesn't work out.
EDIT 3: I'm not sure if it's part of the setup process but the word "UP" then a short progress bar appeared on the screen, now I've got only a black screen with a status bar (4G icon is there but no clock). I have rebooted from the power menu, let's see what's going on here.
EDIT 4: Cache wipe from stock recovery didn't work, trying factory reset from stock recovery. I note that the first time I set up the phone it was plugged into the computer with ODIN still running, I don't think it could have interfered but I unplugged the phone this time just in case.
EDIT 5: I'm not sure if it was ODIN or needing to do a factory reset but it's working now, I'm running through the set up. WiFi is working 100%.
Final EDIT: Everything is working 100%, tested the camera, proximity sensor, screen rotation, voice calls, mobile data, wifi and it's all 100%.

glad to hear it mate, you did it!!
Thanks for let in us know.
For any other Aussies out there trying this I'm on day two and everything is working perfectly, getting root is super easy too, just use Odin to flash a custom recovery (Solk's CWM from May 2014 works great), boot into the recovery and install UPDATE-SuperSU-v2.45.zip, exit and when it asks if you want to repair root say yes. Reboot, go to the play store, update to the latest SuperSU and all is well.
Hi Guys
This is my first post on xda even after using these forums for years. But today I cant find a solution on here or anywhere for that fact, and was literally hoping that I've missed something somewhere.
So to start. I have a Samsung Galaxy J5 Prime (SM-G570F). The other day I was flashing a custom rom when something went wrong during the flashing process and left me with a bricked device. Now I did do a full backup before flashing as I've learned the hard way how important this is. During the flashing it also asked me for a full wipe and to backup the EFS. Even though I did do all the backups and wiped everything< I've ticked both boxes and proceeded with the installation. Everything seemed fine but on 99.9% it froze. Not wanting to do anything I left it until it rebooted the phone by itself, where I was greeted with the download/flash screen. Didn't even give the warning about installing custom software and asked to continue. It just booted straight to the download screen. Tried getting back into recovery only to be greeted with download screen. No matter what I did it just kept booting into download mode. So I then re-flashed TWRP. Getting into the recovery I was able to mount EFS, System, Data, etc. Bu all showed 0mb of 0mb available. I then went to restore everything only to find that the SD Card was also wiped by the process. Thinking that maybe the recovery isn't reading everything correctly, I found the SD Card empty in windows also. No call me names or whatever, (I know my own stupidity) but I never backed up my backups on my PC. So I just proceeded flashing stock firmware as to start from scratch. Everything went as planned until the device got reset by odin. I was greeted with a screen saying "installing system update", but as soon as it reach 32% it changes to "erasing" and then "error" with the "DRK Missing" error. Then it boots to recovery where an error message is saying "unable to mount: EFS (Device or Recourse busy). I cleared cache and did a factory reset and it booted the system (Though mount error still appears in recovery even in custom TWRP/CWM recoveries also). Now I have a 00000..... IMEI number and no network connection. I've spent the last week on the web trying to find a solution with no luck. I'm tired AF because I didn't sleep trying to solve this. I tried flashing stock and custom roms, recovery's, boot-loaders, modems. Tried different software's like Samsung Tool, IMEI repair tool, Strings of adb commands, xposed modules, apps, terminals, etc. I even flashed factory binaries with no luck as to how to change it back.
So in short.
My EFS got wiped.
I lost my IMEI.
I don't have any backups.
Been awake for a week searching for solutions with no luck.
So please if anyone knows of a way to change the IMEI, please help me. I know It's illegal to change IMEI (though not in my country). But I down't want to change it for all the wrong reasons. I just want to change it back to the original found on the back of the phone and on the box. This can't do any harm can it? Please I just want my phone back please!

If this problem is still open, then on Your Phone box is writen imei, or take battery out and under serial number there will be your imei, root your device and use IMEI changer grant root access and type your imei in it, after that reboot and your imei should pop up! I had same issue and this steps made my day! THIS WORKS ONLY ON YOUR IMEI, YOU CAN'T CRACK, STEAL IMEI By this method, don't believe those Dumb ****'s from YouTube!
May I help You!
