Update: I upgraded my phone with XXKI3 2.3.5 firmware, from XXKH3.
The lag is gone, definitely a big improvement compared to XXKH3 version. The phone is very responsive and fast. Quadrant shows 4200+, pretty impressive:

The bootloader was updated, you cannot reset anymore your phone with a download jig. However, Intratech uploaded the old bootloader:
Intratech said:
If you've already flashed a full package from elsewhere and cannot reset your binary counter using the Jig just flash this package in the PDA or Bootloader (Yes both will work) section of Odin to replace the bootloaders and then you can reset the counter: http://www.multiupload.com/LQQBRQVJUD

Personally, I flashed the file with Odin (PDA).
The phone ring is set to silent, instead of default "Over the horizon" ringtone. Make sure you change it, your phone is not broken. See the complete list of changes, related to previous ROM.
Guide
I'm posting this procedure in a separate thread, as is easier to be linked into different forum posts. My Bell Canada phone came originally with the UGKG2 firmware, so everything listed below is based on my own experience with this version, I do not know or confirm it will work with other firmware. I currently run the official (?) XXKI3 Gingerbread 2.3.5 firmware, downloaded from samfirmware.com site (see details below). This is a wipe device release.
Personally, I read that other people flashed their phones with a different firmware... but I did not wanted to do it on my phone. I sticked with the same family XXKGx, just to be safe. Please read Electroz's explanation below.
There are 3 types of release builds: leaked, Frankenstein (compiled and tested by devs, based on demand) and official (Kies updates).
The procedure is simple (I presume you are familiar with Odin, Download Mode &Co.):
1) Get yourself the stock firmware and kernel (thank you Intratech)
2) Setup your drivers properly, avoid the Kies insanity (see below)
3) Flash the new firmware (my flash procedure, you can/should skip Re-Partition/PIT as Intratech explained)
4) Flash phone with CF-Root (I used the CF-Root-SGS2_XX_OXA_KI3-v4.1-CWM4.zip file)
5) Wipe (cache + factory reset)
6) Uninstall all Samsung crap and install additional system apps (i.e. Car Home)
7) Flash back the stock KI3 kernel (thank you Intratech, password: [email protected])
8) Wipe (cache + factory reset)
9) Connect your device to a download jig, to reset the flash counter (old bootloader needed)
Phone & Modem Drivers Setup
Note: This procedure was tested with Windows 7 Ultimate 64bits. If you already installed Kies, uninstall all related software/drivers and clean your registry. Or do a clean Windows install just to be safe.
1) With your anti-virus off, put your phone in Download mode and connect the USB cable. Windows Update will start to download right away the modem and USB drivers. Make sure you select the Windows Update option, when asked into driver install window.
2) Once the modem drivers installed, disconnect the cable, reboot the phone in normal mode and reconnect the cable again. A new set of drivers will be installed for the rest of USB interface.
Important: You need do it in the SPECIFIC order mentioned above, or else the modem drivers will not be installed and you will not be able to use properly Odin. I know this because I tried the other way around.
Initial Phone Setup
Once the phone rebooted, you will be welcomed to the Android Setup.
1) First, set the language from English UK to whatever you like.
A Network warning related to Date and Time will pop, tap on Cancel.
2) Tap the Android robot and setup your phone.
There is NO need to change any other settings, the phone will automatically detect the Bell network.
If for some reason it does not, once you completed your basic setup go to:
Settings > Wireless and Network > Mobile networks > Network operators
It will start the scanning and pop 3 Bell networks, pick the first one. Again, this is in case your phone does not work with calls, voicemail or SMS.
Notes
You should uninstall the CWM app once you flashed back the stock kernel, is half useless. I tested the new Superuser app from Android Market, it will properly upgrade to latest version and also upgrade the su binary on XXKI3 firmware. If you plan to poke around your phone with the Terminal, you will lose all the fancy Linux commands. (grep etc.)
Personally, I purchased ChainsDD's Superuser Elite key. It will allow you to pin protect your rooted device, among other useful things that are planned to be added (built-in terminal). I upgraded Superuser to version 3 and everything works properly.
Battery Power Savings
I always leave my phone with all default options, including screen auto-adjust. The only options I turn off are:
Settings > About phone > Software update > Auto update Disabled
Settings > Applications > Samsung Apps > Off
Personally, I have no idea who started the battery calibration myth in S2. It is useless to "overcharge" the battery, as the software has a check to stop automatically the charge once the battery is 100% while the battery itself has a build-in controller that can't be wiped.
Example of battery stats with the phone in idle mode for approx. 18hrs (86%) and 109hrs (2%):

CSC (Cell Site Controller)
The default CSC setting in XXKI3 is KOR. You can check it with: *#272*{IMEI}#
where the {IMEI} value represents the 15 digits of your IMEI (International Mobile Equipment Identity).
I personally used the default option (KOR) and the phone works perfect, with great reception:
There are some people who wonder if they should change the CSC. I will quote Intratech on this matter as he answered perfectly to my question:
Intratech said:
Some people do and some just use the CSC packaged with whichever firmware they flash. As long as your APN and SMS/MMS settings are ok there is no need to flash another CSC package.

Fast Dormancy
Some people noticed that their network idle on 3G, instead of HSPA+. That is absolutely normal, because of the "fast dormancy" feature. If enabled, HSPA+ will rapidly disconnect from the network once the information is sent or received. That will penalize the actual network you are on, unless the carrier network and your phone talk to each other in a way that takes battery life as well as network congestion into consideration. For this to work, both networks and smartphones have to implement a standardized version of the fast dormancy feature. Bell Canada supports this feature and by default Fast Dormancy is enabled into XXKI3 firmware.
You can check it with: *#9900#
You should call your carrier to see if they have it implemented. Probably your tech support will look like you are speaking Chinese and escalate it to a more knowledgeable guy. This is the average download speed I get on XXKI3 (network is switching automatically on HSPA+):
There are some reports where people confirmed that the UGKG2 build allowed you to reach faster download speeds (up to 9MB). Personally I think 6MB over a cell network is already more than perfect for tethering, not to mention that there are many factors to be taken into consideration when you deal with a wireless transmission. (location, tower antenna, weather, etc.)
Random Restart
The screen needs minimum 500Mhz to get out of Sleep Mode. Some custom ROM's use a low voltage or "underclock" feature that reduces the power consumption but also the number of CPU steps. That is what makes your phone crash and reboot randomly. If you use an external sdcard, do a sd wipe just to be safe. It should take several hours, so do it over the night. Personally, I did not experienced any random reboots using neither the XXKH3 or XXKI3 firmware.
Some people might have bad battery contacts on their S2. Basically, the phone shuts down while in your pocket. Clean the battery terminals with some audio head tape cleaner and cotton swabs, than make sure the contacts are proper.
You could also have a RAM (hardware) issue. Bad memory degrades fast so you will see your random reboots pop at a faster frequency. If you did all the above and still experience random reboots, run adb logcat to see what is going on at that specific moment. If you get error codes like:
Code:
code 1 (SEGV_MAPERR), fault addr 00000000
you are dealing with bad memory unfortunately and need to service your phone.
Manage system apps with Terminal
Personally, I decided to stick with a terminal for now, I feel more comfortable to see what is going on with my own eyes in my phone. A good alternative to Terminal would be the SystemApp Remover, is faster and more robust compared to Titanium Backup as it does only one task (backup/remove system apps).
I did an output list of all the packages:
Code:
$ pm list packages -f >> /sdcard/packages 2>&1
so I know now where each package is located and what is the associated name.
All I have to do is run:
Code:
$ su
# rm -f /system/app/package.{apk,odex}
# pm clear PACKAGE
# pm uninstall PACKAGE
Running "mount | grep system" tells me right away where and how /system is mounted:
Code:
/dev/block/mmcblk0p9 on /system type ext4 (ro,relatime,barrier=1,data=ordered)
so all I have to do is change the mount perms to write, instead of read:
Code:
# mount -o remount,rw /dev/block/mmcblk0p9 /system
Package Manager commands:
Code:
# pm
usage: pm [list|path|install|uninstall]
pm list packages [-f] [-d] [-e] [-u] [FILTER]
pm list permission-groups
pm list permissions [-g] [-f] [-d] [-u] [GROUP]
pm list instrumentation [-f] [TARGET-PACKAGE]
pm list features
pm list libraries
pm path PACKAGE
pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH
pm uninstall [-k] PACKAGE
pm clear PACKAGE
pm enable PACKAGE_OR_COMPONENT
pm disable PACKAGE_OR_COMPONENT
pm setInstallLocation [0/auto] [1/internal] [2/external]
The list packages command prints all packages, optionally only
those whose package name contains the text in FILTER. Options:
-f: see their associated file.
-d: filter to include disbled packages.
-e: filter to include enabled packages.
-u: also include uninstalled packages.
The list permission-groups command prints all known
permission groups.
The list permissions command prints all known
permissions, optionally only those in GROUP. Options:
-g: organize by group.
-f: print all information.
-s: short summary.
-d: only list dangerous permissions.
-u: list only the permissions users will see.
The list instrumentation command prints all instrumentations,
or only those that target a specified package. Options:
-f: see their associated file.
The list features command prints all features of the system.
The path command prints the path to the .apk of a package.
The install command installs a package to the system. Options:
-l: install the package with FORWARD_LOCK.
-r: reinstall an exisiting app, keeping its data.
-t: allow test .apks to be installed.
-i: specify the installer package name.
-s: install package on sdcard.
-f: install package on internal flash.
The uninstall command removes a package from the system. Options:
-k: keep the data and cache directories around.
after the package removal.
The clear command deletes all data associated with a package.
The enable and disable commands change the enabled state of
a given package or component (written as "package/class").
The getInstallLocation command gets the current install location
0 [auto]: Let system decide the best location
1 [internal]: Install on internal device storage
2 [external]: Install on external media
The setInstallLocation command changes the default install location
0 [auto]: Let system decide the best location
1 [internal]: Install on internal device storage
2 [external]: Install on external media

This is wrong. I'm not sure where you got that XXKG3 is remotely the same as UGKG2, but here's an explanation of the firmware version numbers:
This is standard across most Samsung Phones.
I9000 = Model #
UG = Carrier/Area code. For example, XX = Europe, UG = Bell Mobility Canada.
K = Year = 2011
G = Month = July (H = August, I = September)
2 = Revisions that month for the specific region (aka. UG, XX, XW).
A lot of people on here think the last 3 digits are important and that if you have 2 KG3 firmware that they are the same. However, this is not the case.
You need to go by all 5 letters due to the fact that each firmware is customized by different groups at Samsung. And to prove this, just look at KG2. There are 2.3.3 KG2's and there are 2.3.4 KG2's.
It's actually possible that one area's KG2 could have been newer than another area's KG4. The best way to check, is to look at the build date in the Build.prop for each firmware.
But your assuming that KGx means they're the same is wrong. All that those numbers mean is what month/revision the firmware is. Samsung has several different teams producing firmware independently of each other for different regions. The only letters that mean the firmwares are similar are the country/carrier code (ie. UG, XX, XW).
Also, your idea of what Official firmware is, is flawed. Just because it's on samfirmware, DOES NOT make it official. Most of their firmwares are leaked test builds. If it's not released on Kies, it's not official.
Thanks for the great explanation, much appreciated. It should help many people understand better how the versioning works. About the "official" part, that's the reason why I mark it with a (?). As you said very well, it is official once is released by Samsung through updates.
The thread is related to my own experiences with the Europe MULTI firmware, based on the fact that a Bell phone specs are identical to the Europe model.
Edit: I upgraded to XXKH3 firmware successfully just now, everything works great.
I currently have a Bell branded SGSII with baseband version UGKG2.
I originally flashed it with CF-Root-SGS2_ZS_OZS_KG2-v4.1-CWM4.zip and then I re-flashed it with the original UGKG2 Stock Kernel from Bell.
Now my phone is rooted and stock.
Any positive/negative feedback from users running XXKH3 firmware (2.3.4) would be very much appreciated.

I ran the KH3 firmware briefly with no issues. The only annoying this was when using the program monitor widget I would experience some lag or choppiness when switching homescreens(same on KG6/KH4). On the positive side the gps accuracy and lock time was greatly improved.
Aha, I had no idea as I don't use that widget... thanks for the tip.
I usually hold the Home button until the Task Manager pops, to see the running apps. But I got used already to press the Back key every time I deal with an app... that automatically closes it.
About the GPS, the accuracy is greatly improved indeed. It takes me 1-3secs max to get a lock (with wireless networks disabled) and the accuracy is always 5meters.
Edit: There is a new Digital Clock service running now... I have no idea what makes it start, please let me know. I use Beautiful Widgets on my home screen.
The digital clock service should be part of the digital clock widget. You can try to end the process under running services and see if it stops it.
I downloaded the XXKH3 firmware but I'm not sure which files I should be using with Odin (Bootloader, PDA, Phone & CSC).

I use Beautiful Widgets, so DigitalClock.apk should not be starting... Weird.
I just uninstalled the system app, no more running services. It was wasting my battery for nothing.

See step 3 and skip the PIT file (re-partition unchecked). Also see the Update note into OP.

I ended up re-downloading the XXKH3 from Intratech's thread and it was much easier flashing the one PDA file.
Now do I need to flash the XXKH3 stock kernel or my default stock Bell kernel?
You need the XXKH3 stock kernel, Intratech has it linked below the actual firmware link.
does it matter if CSC changes?
right now, (before root + update firmware), I still have BMC....
but once it's changed, would that create problems? If yes, what kind of problems. If no, then why do we care about CSC?
Personally, I used the samfirmware files and the phone works great. The pda.bell.ca info is present into ASN also.
Thanks for the responses everyone.
I ended flashing the stock XXKH3 kernel with the firmware. So far the upgrade has been good to me, I noticed improved battery life for the first 18 hours of usage. I will continue to use this build until I find something that is more stable and efficient then this.
A BIG THANK YOU!!!! I finally rooted and unlocked.
Originally: UGKF6
Now: XXKG5
Thanks for the guide!!!
Just 1 question though, do I HAVE TO do a factory after root? Any problem if I don't?
One thing is sure, the battery life degraded compared to XXKG3 firmware.
XXKG3 | XXKH3 (about 4hrs lost)
When I took the screenshot on KG3, I was using the phone for about 2 hours to read a book (notice the sudden drops because of the white screen), while the KH3 was always in sleep mode. So ya, there is a significant change in battery life with a tradeoff for the GPS gains.
I updated the OP.

Just curious, why you did not used the KH3 to take advantage of amazing GPS? The battery life should be a bit better also, compared to KG5. What do you mean by "do a factory"? You will lose root only if you flash back the firmware, flashing the kernel will not delete the su binary. You want to keep your phone rooted.
I strongly recommend you to spend $1 and get ChainsDD's Superuser Elite key, it will allow you to pin protect your rooted device. I upgraded to 3.0 Beta4 and everything works properly. Worth the dollar in so many ways, not just for securing the su access.

I use Titanium Backup PRO. It allows me to backup, freeze and uninstall the unwanted apps.
One thing i have see with the XXKH3. With the KG2 im stable on H+, now im switching between 3G and H+.
Anyone else?
See Fast Dormancy info in OP. Is normal and the intended way to save you battery and bandwidth congestion.
Hello,
First of all, I need to say I searched for weeks to solve this issue. I found no other way than posting a question. I hope someone could help me solve it. I checked the logs using "aLogcat" but nothing is relevant to the GPS. Any kind of help is welcome, I am not asking for a full step-by-step guide
* Issue: GPS cannot find my location, even when kept for long periods under clear sky (20 minutes). I tried "Faster GPS" and "GPS Status" apps to debug the thing, but useless. I simply can't get a fix.

Thank you
Ever since I upgraded to KitKat months ago I've had the same problem. Location is found, but satellite will never fix which means no turn by turn navigation.
I've downloaded every GPS app that exists, calibrated the compass countless times...and still nothing. In that time, I've installed and run at least 10 different ROMs and odined to stock as well.
I'm thinking it's a hardware problem and might exchange my phone for a replacement S4. Searched for GPS/KitKat/S4 problem, but never found anything significant.

Normally, the GPS should be able to fix satellites even without Data (In Airplane mode) and without AGPS data also. But I get zero fixes whatever I try. I am trying to keep the "hardware possibility" a last resort. I am trying to find a software solution to a software triggered problem (the upgrade, it seems...).

The fact that I have done everything possible and it still will not fix to any satellite makes me convinced this is a hardware problem.
However, since this only started when I first upgraded to KitKat (didn't take any OTAs) I'm holding out hope there is some type of fix that we're overlooking.
Any additional help or advice from anyone else would be much appreciated, thanks in advance!
I finally resolved my issue
Current situation: GPS fixes 8 satellites out of 25 even between high buildings.
Short solution: set the right CSC for your device.
Advice: Always set the right CSC for your device, even if you happen to mess with it (which is arguably your own right as you own the device...).
Long solution:
- Backup your data and your apps. During the procedure, the device !!!WILL PERFORM A FACTORY RESET!!!
- Root your device.
- Open a terminal emulator on the device.
- Type the following commands (let the terminal application gain root access when you get prompted):
$ su
# am start -a android.intent.action.MAIN -n com.sec.android.Preconfig/com.sec.android.Preconfig.Preconfig
- You will get a window with a list of CSC codes. Select the one corresponding to your device and stock firmware, and push the button INSTALL.
- The device will reboot, and !!!WILL PERFORM A FACTORY RESET!!!
- That's all folks.
- (Now go mess up things again, and again...)

Install SELinuxModeChanger app from google play and change the permission from enforcing to permissive. Should fix your gps problem.
A WiFi-related bug in Samsung's recent 5.0.1 Lollipop update causes devices to go into a continuous reboot loop (rebooting every 1-1.5 minutes) after certain conditions.
Known affected devices:
Samsung Galaxy S4 International (GT-i9500) on Android 5.0.1
Samsung Galaxy Note 3 International (SM-N900) on Android 5.0.1
If the device comes in range of an open wireless network with blank/no SSID, it attempts to connect to it. This adds the network to the list of known/configured networks with the network name being null. The next time WiFi is enabled (either through manual switching or a reboot), the WifiStateMachine goes through the list of configured networks as usual, checking each one. A String .equals() method is called on the name of each network, so upon reaching the null network the following fatal NullPointerException is caused, rebooting the device:
HTML:
I/WifiConfigStore(13460): null is a captive portal!
I/WifiConfigStore(13460): not authenticated yet
E/WifiConfigStore(13460): Not a HS20
E/WifiConfigStore(13460): Not a HS20
E/AndroidRuntime(13460): *** FATAL EXCEPTION IN SYSTEM PROCESS: WifiStateMachine

E/AndroidRuntime(13460): at android.os.Looper.loop(Looper.java:145)
E/AndroidRuntime(13460): at android.os.HandlerThread.run(HandlerThread.java:61)
Solutions:
Enable Airplane Mode: reboot loop will end after next reboot as WifiStateMachine does not check networks if WiFi is off at boot
Factory reset: the list of configured networks is cleared, so the error-causing network is removed
The ideal workaround would be to delete the error-causing network (or all configured networks) without a factory reset, but networks can only be removed the normal way when WiFi is on and removing them from the shell requires root access (to delete a system file).
I have not been able to find a way to report this to Samsung.
EDIT 1: It looks like this bug only applies to null networks that have captive portals/require browser sign-in.
Hey,
I've got this bug on the S6 edge too
Since I'm rooted, maybe I can fix it without factory reset??

If you're rooted, a possible solution might be to remove the null network from the wpa_supplicant.conf file. I'm not sure where it is located, possibly /data/misc/wifi/wpa_supplicant.conf
I don't think there is a real 'null' wifi anywhere...
Anyway, I managed to fix my problem thanks to application on the market, see this post : http://forum.xda-developers.com/showthread.php?p=60349787
Sent from my SM-G925F using XDA Free mobile app
For me it wasn't `wpa_supplicant.conf` that was causing the problem, it was
`/data/misc/wifi/networkHistory.txt`
I deleted this file and my tablet returned back to normal
This is stackexchange issue I raised on this issue :
<a href="http://android.stackexchange.com/questions/171241/wifi-hotspot-timeout-setting-gone-in-nougat-7-0-7-1-but-timeout-has-not">
Wifi HotSpot timeout setting gone in Nougat 7.0 , 7.1, but timeout has not</a>; .
(answered only by myself).
I have observed, on receipt of my new AGM A8 QualComm 410 MSM8916 Android 7.0 phone , that the Wifi-HotSpot keeps timing out
after 2-5 mins . I am trying to connect my Linux 4.10 x86_64 host, using its iwlwifi driver, and wpa_supplicant + ISC dhclient, and it
does connect fine, for 2-3 minutes, but then the android phone (default DHCP router) stops responding to ping requests, and the
link is dead , until I bring the device down on the linux host & kill & respawn wpa_supplicant & dhclient . The script I use to do this
is attached. One weird thing is that even though the Android device stops responding to pings, it may still be passing pings through
to the WAN internet , so my script has to trying pinging an actual internet address like www.kernel.org (one of the few public IP
addresses left that respond to ICMP).
This is really nasty of Android Nougat, especially as the previous Android version I used on my old phone (4.2.2)
had a Wifi-HotSpot Timeout Options Settings dialog , which let you specify inactivity timeouts .
So I had to develop this complicated workaround where my 'network' init.d script does
PID_FILE=/run/wlan_ping_monitor.pid daemon /etc/init.d/wlan_ping_monitor.sh
which keeps the link alive.
I really need to root this phone, so I can install my own /etc/hosts file / ISC BIND9, fix this issue in /etc/default.hostapd.conf settings,
and maybe try to fix hostapd , & be able to view logs .
Any advice on how to create a custom recovery for this phone ? latest TWRP & CyanogenModROMs do not support it.
It looks similar to the WileyFox Swift , for which there is a lineageos 14.1 build . Should I try this ?
I am focusing on trying to build android & android_bootable_recovery and android_rooting_tools gitweb gits, & then build AOSP
& TWRP & a recovery ROM - any advice gratefully received.
This is linux kernel bug : https://bugzilla.kernel.org/show_bug.cgi?id=194931
and stackexchange issue: http://android.stackexchange.com/qu...ng-gone-in-nougat-7-0-7-1-but-timeout-has-not
The kernel could be responding better to the empty data frame sent by Nougat hostapd on ap_max_inactivity=300 timeout.
Also wpa_supplicant should be detecting the link has gone dead & re-initializing .
