Samsung Galaxy S II :: Firmware Upgrading And Unlocking?
Sep 2, 2011
I am living in Toronto, Canada and bought the phone from a cellphone shop and paid the shopkeeper extra for unlocking the phone. Q-1.) Will my phone be locked again if i was to update it?Q-2.) How can i update my phones firmware to 2.3.4 without voiding warranty? or it is not possible?Q-3) Is there any way to know what is the unlock code that was used to unlock my phone so in case i update it and gets locked i can put the code myself without having to pay to have it unlocked?Phone Info:Model Number: GT-I9100MOS Version: 2.3.3Baseband Version: I9100MUGKG2Kernel Version: 2.6.35.7-I9100MUGKG2-CL371789dh130.yoo@SEP-48 #2Build Number: GINGERBREAD.UGKG2

I just rooted and unlocked a SG2 that was on the 3 network. I ran Galaxy S2 SIM Unlock after rooting using ODIN etc - I put in the unlock code and it said unlock successful. After putting in my Orange SIM and switching on, I am getting the network error symbol and am unable to make calls. (Interestingly, I do get the Orange SIM Plus app icon on the phones desktop. Also, the phone still boots with the 3 logo - was expecting this to have disappeared completely!).

Is it possible to change the look of the unlocking screen on the S2 to something a bit more interesting like the one found on the htc?

Just updated via Samsung Apps the camera firmware to a CDE11 or something version. Took 4 minutes to update and flash this firmware. I wonder what exactly it changed in the camera firmware? Hopefully improved things or bug fixes.I will test a few videos and see if the bitrate has changed or not.

Connected Galaxy S11 to Kies and was informed a Firmware upgrade was available. Current was shown as PDA:KF3/ PHONE:KE7 / CSC:KG2 (O2U) New shown as PDA:KJ1 /PHONE: K14 / CSC :KJ1 (O2U)It started off Ok and downladed firmware. Checked encryption of binary, unpacked binary, changed the picture of computer/phone to grey panel and started downloading to phone. Phone shows gren robot and "Downloading... Do not turn off target". It downloaded 11% and stopped.That was at 1540. It is now 1710 and it still shows 11%?

samsung galaxy s ii a month ago and i noticed 2 bugs (i hope not faults).the first bug is the notorious pink spot.even after 2 firmware upgrades,it`s still there.the second bug and the most annoying is the fps drop.in low light conditions (and i mean inside or night),when autofocusing,the fps drop dramatically,like in this video (http://www.Internet.com/watch?=wkqe_62ee6y).again,after 2 firmware upgrades,it`s still there.i really don`t know what to do.i searched various websites and forums and the only "solution" i found is for the pink spot [the solution is updating to ke7,but my version is kj4 (the latest in my country and above ke7)],but still no luck with that.

PC is running Windows Vista Ultimate SP2 (64bit version) I have Kies version is 2.0.2.11071_128, The upgrade starts ok and runs until the phone displays 'Downloading...' at which point I get the message 'PC failed to recognise the mobile phone.' and says to disconnect phone, remove battery, restart phone and try again. This i have done several times but the same thing happens every time.

I accepted doing it, so it backed-up some of my data and started the installation. The progress bar remained at 0% for more than 40 minutes and I became suspicious that it was not working. I tried interrupting with the cancel button and that didn't work, so the only way was to remove the cable (yes there were warnings not to do it... still I assumed that this scenario would have been foreseen). Kies woke up with the interruption and asked if I wanted to do an emergency firmware recovery, I said yes and proceeded with it. It gave me some instructions to switch off the phone, replace battery, and remove the cable. I switched the phone off and on again and there appeared a symbol representing the loss of connection to the PC, so I re-connected. The recovery started fine, but half way through it, it failed due to a problem on the phone. Since then the phone is dead. It won't start anymore.

I got my S2 a few months ago with O2 and I noticed that they had released the firmware for ICS. So i was forced to download the truly terrible Kies software, and after 24 hours of it not even connecting to my phone, I actually got it working. Of course, now, it wont even recognise that i can get ICS. I says I have the latest firmware -which I dont- and wont even let me search for a new one!

I''m trying to update the firmware on my Galaxy S2 (or GT-i9100) phone through Kies 2.1.1 on Windows 7 x64.. If finds the update available for the device and shows windows to update firmware. The new/latest update version available is PDA-KL1/PHONE:KL1/CSC:KL1(INU) After clicking to update, it downloads the update and goes into next step of "Preparing firmware update components", but then the process terminates after few seconds and nothing happens. The phone reconnects to kies s/w and again the firmware upgrade window is shown. So cannot update the firmware.

Kies (2.3.2.12064_9) stated that a firmware upgrade was available so I started the process. The files were downloaded and the connection to the phone established. All seemed to be going to plan. Then the phone dropped out of Kies and is trying to reconnect. The computer flashed up a message that the device was not recognised. The phone is still attached to the USB and has the android icon with downloading...do not turn off t Is the phone already disconnected..?What should I do to recover? Can I recover?

I've got the latest version of Kies 2.3.1.12044_18, and have checked for updates.I'm an UK O2 customer, but with a replacement handset that was provided by an insurance company rather than the original carrier supplied one.Kies says the current firmware version as:
PDA:K14 / PHONE:KI1 / CSC:KE1 (MTL)
And says this is the latest firmware.Which seems incorrect, as the phone is still on Gingerbread.

I thought I'd start a new thread to prevent going too far off topic on another thread that I asked this question on."If you want to go down that path you are better to root, unlock (via the market app) and then flash the XEU to your branded phone, and it will debrand it.It's all in a sticky on the Development link.EDIT: I've been using this root method and works well.For me downloading this file worked best and selected he 'touch' option http://clockworkmod.com/rommanagerTo avoid confusion it's this download: 5.8.1.5"Completed the above as advised by greenman and am now rooted (superuser installed and rooted apps work OK), but when trying apps to unlock phone I get no luck. Messages like "No code found etc from 2 apps I tried.

Kies recently updated firmware on my SII & loaded kies update to PC as well. Now when I sync with outlook 2007 it sets all meeting times to start & finish at the same time on the phone. So apt created in outllook to start say 8am & finish 10am. Sync then puts it in phone calendar but set start AND finish to 8am. I rely on this so really need it fixed.

After the firmware upgrade I seemed to have lost the 3g signal, before I would hardly see the "E" signal, mine was always the "H" or the "3G" but now all I get is the "E" with rare signs of the 3G signal, this has of course made my internet very slow!

I have an S2, running latest firmware and cannot add my IMAP account to it. I have my gmail, hotmail and exchange accounts setup fine. But when I try to do the IMAP account, I enter the login details, server etc., and when it tries to test the incoming side of things it force quits. I've rebooted etc.
