Extremely confused - Galaxy S II General

I've had the SGS2 for close to a month and in this time, i swear to honest God i've been more confused then i've been during my Symbian authoring days with my N95. I'm a tech savvy individual that reads up and researches things to death before acting but i'm just dumbfounded.
I have a Vodafone Romania SGS2 with the fallowing firmware: PDA: KE1 / Phone: KE1 / CSC: KE1 (CNX). I want to update to the KE5 firmware Kies is apparently showing me but due to a CTD Kies refuses to work and actually froze up my PC.
After repeaded tries, reinstalls, updates and tweaks i gave up on using Kies, especially after reading that it bricked some phones. So on i went to manually flashing it with Odin. I didn't get far because i've stumbled upon the thread with the official ROMS. So far i just want to install the official honest to god KE5 update for my network, to not mess anything up and still keep the warranty.

So, i assume i need the BUKE5, which is the KE5 update, the full one, not the kernel alone? So i go there and the filename is: GT-I9100_VDC_I9100BUKE1_I9100BUKE1_I9100VDCKE1.exe (265.11 MB)
Am i just paranoid or is that not the correct firmware update? Also, upgrading the firmware needs to delete all my apps and app data. I backed them up using astro and the kies software to the best of my ability, but i ended up being stonewalled that doing anything, from firmware to rooting to etc, lands me with more work to be done restoring the apps and settings after i'm done with it.
I just had so many issues with the phone, and in the end it doesn't seem as 'smart' as i though it'd be. Everyone had high praise for it and to be honest, after beating around with it so much, i really wish people would have told me about the numerous issues it has before buying. Sadly, only glowing and positive reviews. -.-
In the end, can someone please help me atleast update the firmware?
LE: Forgot to mention in case of the Kies, Win7 Professional.

external sd card doesn't get wiped. Internal sd card doesn't get wiped.
You could try a no wipe root by just flashing a rooted kernel like chainfire rather than full rom. Then backup user apps using titanium.
Use odin for both and generally only use PDA file, and defaulted options like reboot and do on. See various kernel threads for that.

The difference its that chain fire adds recovery tools but its only a kernel. You can add that later if you want.
After that, first full custom rom or rebranded rom does mean /data which are user app data directories may get wiped.

Ok then, so i'm installing CF kernel to make a full backup for one thing. I get to the post, stumble around only on google with fake versions to see Odin at the bottom of the post attached. Get that, get the Zip, then get to the 'put your phone in download mode'. Ok i guess that's the USB mass storage? Two minutes later.. nope. More google. Realise it ment to reboot the phone in download mode by pushing Volume down, power button and the home key.
Right, finally i manage to install the CF kernel without issues. Now i accessed Titanium Backup and begin backing up all it can.
Will keep updated here.
After a bit of searching, i found Intratech actually put the wrong link up for the BUKE5 update on the vodafone network for Romania. I PM'd him and waiting for an update.

Good Luck. I'm sorry to hear you have had so many problems.
With regards to your warranty, you can always Odin the stock firmware and buy a USB Jig (devs are currently working on a software solution, should be cracked soon removing the need for the jig) from ebay to reset the custom ROM counter before you return the phone if needed.

The very next day, i got the BUKE5 firmware update and installed it succesfully. I will continue by rooting the phone with CF again and i should be done.
Atleast i got my 'totally painless easy-to-update firmware'.
Later edit: Seems there is no KE5 CF root. -.-

You probably do not need ke5 root.
So called insecure kernel only needed for two things.
1) flash secure rom (ke5) then insecure kernel (ke2 or ke7 kernel only) that you flash over your secured rom (ke5).
Insecure lets running one click root, that installs super user and busy box.
That is what you do I guess.
Then optionally you flash regular kernel (ke5) kernel only, not whole rom. You will keep super user and root but I lose adb root which you probably will not miss.
2) flash custom kernel. E.g. one like tegrak for cpu flexibility, or one like chain fire keep for custom recovery if you like
Cmw recovery
.
So get the latest that is compatible. New over old its often okay.
ke7 or kf2. Or do what some are doing and wait for ke9 (rumoured gingerbread upgrade release from samsung) that on my magic was a big upgrade in performance)
You get to do great stuff like tegrak over clock app with both 1 and 2.
Advantage of (1) is that flashing a genuine kernel after an insecure one used just too get root gets rid of that yellow ! you get with custom kernel when you boot the phone that could alert an engineer with a warranty claim.
Or stay on custom kernel and use a jig like previous poster said to clear the alert. Two pounds fifty well spent.
Advantage of (2) is that recovery installs are very convenient, and do not put the ! warning. Oh and updating phone on the train gets funny looks from fellow passengers looking over your shoulder.
On the other hand some people like using odin anyway "because that's what samsung engineers use"

First Get your selft updated to 2.2 or 2.2.1 if available.
1) then look for CF-Root in xda ...that will help you...
2) If not then install OCLF from Market and root it.
3) Use SuperOneClick ... Be sure to read manual first.
To elaborate a little on the last post....first try to update to 2.2 or 2.2.1 through your local service provider or by using Kies (available from Samsung, their official firmware updating tool). However Kies does not work in all regions and is very finicky, and you should research it here before you try to use it.
As for rooting, I rooted 2.2 directly using SuperOneClick but I believe it can be used for 2.1 as well. You can learn about it and downloaded here at XDA (http://forum.xda-developers.com/showthread.php?t=803682). It is very simple and easy to use but be sure you read the entire thread about it and even watch the video included. Remember forewarned is forearmed.
If you then wish to install a lagfix without changing any other element of your software, then you can use OCLF from the Android Market. Look for it here on XDA and as always, read up on it before you use it. Some people feel that the Ext2 lagfix method OCLF uses is unsafe, but just as many people swear by it, so read up on it, and make your own choice. Lagfixes will often improve your user experience dramatically, especially on on stock firmwear.
Next, you may wish to flash a new kernel. Even more then swapping mods, kernels can bring some very impressive changes to your phone and is also essential if you wish to use Clockwork Mod for backing up and flashing your firmware. The best guide I have found for doing this the first time is put out by Hardcore, and his SpeedMod kernel is a great choice for new users. Find out all about it at http://forum.xda-developers.com/showthread.php?t=822756 and be sure to follow his instructions EXACTLY for best results.
If you decide you want to flash an entire new Mod, there I can't help you (haven't had the nerve to do it yet, but likely will once final Gingerbread mods are released), but there is plenty of great advice around here on that topic, seek and ye shall find.
Good luck
If you want to download paid apps for free you don't need root, you just need to find a place to download the apps from. Discussion of warez is not permitted on XDA though, so you better find yourself another place.

2.1 is a pos against the new very good 2.2.1 roms
Before flashing read more and test your 3btn combo
yea my 3-button-combo works

You can for example install titanium backup and make a backup of your apps and backup your efs folder never know when you need it
Next i would suggest you reed about flashing and if you are comfortable with everything install a custom rom like darky's (beginner friendly) be aware of the risks and have fun with a much better phone
But I think my phone is still Android 2.1 as it says under Firmware version; 2.1-update1 this I obtained from the Settings->About phone.
do i need to update or something cos i still can't update via kies
2. Flashing stock firmwares.
--Why, when, where: You should usually do this if your phone doesn't work with your current firmware, if there is a new firmware out that might work better or if you just want to go to a stock firmware.
--Prerequisites: Odin, a stock firmware (from www.samfirmware.com for example).
NOTE: Apparently there are people that report that using Odin v1.3 might interrupt the flashing and leave you with a soft brick and that v1.7 doesn't have this problem. I have always used v1.3 and never had problems because of it, but if v1.3 isn't working for you, you might give v1.7 (or even heimdall) a try before giving up.
The steps to flashing a stock firmware are already described in a couple of other threads, like: http://forum.xda-developers.com/showthread.php?t=818556
Nonetheless, here a quick sum-up of what you have to do:
2.1. Open up Odin.
2.2. Put your phone in the "Download mode" with the 3-button-combo (Volume Down + Home + Power).
2.3. Connect your phone to your computer (DO NOT CONNECT THE PHONE BEFORE OPENING ODIN OR THIS WILL NOT WORK).
2.4. Odin should recognize your phone and one of the "com" boxes should light up yellow. If this isn't the case, try repeating the previous steps and eventually connect your phone to another USB port.
2.5. Select your firmware in Odin.
2.5.1. --OPTIONAL-- If you want your phone to be like new, you can select "Re-Partition" in Odin, which will make it repartition your Internal SD. In this case you also have to use a .pit file (WARNING -- you will lose all of your installed applications and settings).
2.6. Take a deep breath and click the "Start" button.
2.7. Wait for the firmware to be flashed and for the device to be restarted.
2.8. You now have a stock firmware. If you also selected "Re-Partition" in Odin, all your programs and settings will be gone and your device will be like new.

ok so that is what I am trying to do but when I go to the site I'm not sure which files I should download
I have already downloaded odin 1.8 so does this mean i download the 2.2 america/australia firmware for galaxy s ?

Steep Learning curve these last couple of hours

Excuse the long thread title lol..
I've been gently lowering myself into all this tampering with my phone as I've always been a bit of a tinkerer with everything i've ever owned.
So back in march my phone, an unbranded handset on o2 uk was on 2.2.1. My first foray into modifying my handset was to flash the jvk gb firmware. I then rooted it using cf root. All very simple. I then flashed it using cwm with Simply honey 3.2 and then the latest 3.5. No issue.
So this afternoon, I flashed it with the "unspoken ones" kernel just cos I could lol. Something didnt seem right though. There was a bit of lag and I got one or two forced closures so I decided to restore one of the cwm backups I had. Thing is, it hung upon reboot at the i9000 screen, for about 10 minutes so I pulled the battery. Now I couldnt get it restarted. Panic set in. This was my first proper issue and I just wished I was back in march on 2.2.1 again.
As said, couldnt get it started so went hunting some advice. Install a base stock rom with 3 files and a 512 pit. I struggled. Could I find 3 files ? Nope. Not on samfirmware. Every file I downloaded was one file. JP1 JPU JPY. All 1 file. So. As JPY was the firmware I was on originally, I chose the 1 file version, put the phone in download mode and flashed it via odin. It worked !!! And then I plugged it into kies and up popped the box, I have an firmware update ! JPO GB! So i installed that. I'm quite surprised that I got the update because you always see lots of threads regarding people being unable to update by kies once they have modified their phones. Why did mine work? Because the handset in unbranded perhaps ?
Anyway, I wanted to get back to the Simply Honey rom because it ran really well and the battery life is fantastic but Simone hasnt done a version based on JVO yet as far as I could tell so I thought, I know, I'll root with cf root, again and try that backup again using cwm. And it worked, and here I am back where I was earlier today ! Ace ! lol
Sorry about the essay but I'm sure that there are some questions in there worth answering.. ?...and also to serve as a bit of help to those that find themselves in a dodgy situation. Just calm down, search for the advice, it is out there and do as it says and everything will be cool
Posted from my restored and working handset...
the files you download from samfirmware are rar files (have a .rar extention). This means you need to decompress them into a folder and the "three files" will be in there. You need a rar extractor app. You can use 7-zip which is free.
You need odin (or ezodin or heimdal) to flash the stock rom but I am sure you know that already. There are a few guides around for all tools.
There is a lot of information here, especially in the "sticky" posts. If you feel like learning what you are doing rather than copy instructions (as I think you do), it may be a good idea to go through them.
Anyway you got your phone working in the end so that's good!
simple solution when an install hangs is only to reflash the kernel in odin: that restarts the phone.
cwm is not invincible and the restored rom is there but the phone hangs on the boot because of the kernel hiccup. Reflashing the kernel to the one you now want will allow the phone to boot and access the rom that matches -- you do have to ensure the recovery version rom and the kernel you are flashing are in sync.
Persist. You only really panic the first time this happens -- after that you know it is a possibility and how to fix it.
Worst case scenario: pull the battery, reinsert, go to download mode and reflash the kernel and base rom of your choice. At least now you have a clean phone!
Two things are important to remember: (1) always do a backup before installing a new rom or kernel and (2) use titanium backup for all applications -- easy to restore everything.
Also I find it easier to use google calender and my internet email as bases for dates, appointments and contacts -- that way if I loose everything on the phone I can quickly reload my data by sync with online accounts once I have the phone "rebuilt".

gingerbread for sc-02b

For those with NTT sc-02b. there is a new firmware available on KIES. it is 2.3.3. baseband sc02bomke3. i updated my phone but in my opinion, it kinda suck.
Works good for me. Its much smoother than the previous rom. But, i cant figure out how to root.
Tried super one click and the gingerbreak .apk. they just run forever.
Sent from my SC-02B using XDA App
I just upgraded too.
Works good for me too (actually seems faster from the get-go and I like the new status bar design).
Unfortunately One Click Root is not working for me either.
There are some instructions on how to get it to work already on komugi.net but they are beyond my abilities.
Unfortunately XDA won't let me post direct links yet so here are the instructions copied directly from the site
In Japanese...
この画面を見た時は\オワタ/と思ったのですが生きてました。
・やり方
1. アップデートのdecode済みファイルを入手する。
2. boot.bin と Sbl.bin を抜いてリパックする。カーネル単体のも作る。
3. リパックしたファイルを Odin3 で flash
4. 適当な rootカーネルを Odin3 で flash
5. リカバリモードから suコマンドを送り込み chmod 6755 su する。
(ドコモロゴで止まった場合でもadb shellから操作可能)
6. Odin3で純正カーネルをflashする。
7. 起動後に root になって Superuser.apk とか busybox とか入れる。
8. おわり。
・問題点
リカバリモードに入れない。
毎回起動時に↑画像のように画面が乱れる。
(画面が乱れるのはbootloaderを更新していない事が原因の模様)
・追記
bootloaderのアップデートを行っても特に問題無く「4.」以降の作業が行える事を確認した。
この場合問題点は全て解決される。
従来のCWMはRecoveryの仕様が変わったため使用不可。
English Translation (from Excite)...
It lives and [mashita] . though thought \ [owata]/when this screen is seen.
・Way
1. The file that is decode of the update is obtained.
2. With boot.bin Sbl.bin is pulled out and [ripakku]ed. The kernel unit is made.
3. The [ripakku]ed file With Odin3 Flash.
4. It is suitable The root kernel With Odin3 Flash.
5. From the recovery mode The su command is sent Chmod 6755 su is done.
(It is possible to operate it from adb shell even when stopping in the DoCoMo logo. )
6. Flash does a pure kernel with Odin3.
7. After it starts Become root Superuser.apk Busybox is put.
8. End.
・Problem
It doesn't put it in the recovery mode.
The screen falls into disorder like ↑ image when starting every time.
(It is a pattern that the screen falls into disorder caused by the thing that bootloader has not been renewed. )
・Postscript
The thing that it was possible to work especially unquestionably since "4." even if bootloader was renewed was confirmed.
In this case, all problems are solved.
Because the specification of Recovery changed, past CWM cannot be used.
Hopefully someone will figure out a simpler method soon or dumb it down a bit for me
Yeah. . . Looks rather complicated. I'm hoping for something that can be undone as well, but alas. I may have to finally study up on using Odin and all that jazz.

Chainfire's cf root method can be used to root this version with one additional step. After flashing and booting one time Chainfire's cf kernel you will have to go back to download mode and re-flash the original ke3 kernel. This will leave you with busybox, su, and superuser install in the correct places. You will not have 2e recovery or cwmod and there will be a couple of Chainfire's utilities that won't work on our kernel that you should be able to uninstall. Since none of his kernels are the same as ours I used the newest one from around post 6. I've done this a couple of times and it seems to work well. As always I take no responsibility if you brick your phone. I have attached the original ke3 kernel the tar file inside the attached zip may take a long time to flash possibly because I made it in 7zip instead of booting ti Linux to make it properly.
If your not comfortable playing with Odin and flashing phones I recommend waiting on someone to come up with a safer process.

Thanks for the tips dejanet...
I gave it a try using CF-Root 3.7 and my SC-02B is stuck in a startup loop now... Maybe I did something wrong though? I don't need to select a PIT file in Odin, do I?
I'll give it another go with an older version of CF-Root, but if you have a specific version that you know works and any tips, that'd be great.
I used the newest one. And you for sure don't want to use a pit file or repartition. You might want to flash back to the ke3 kernel first.

OK! Had to reset my phone to factory once for some reason, but then I was able to flash just as you suggested and it worked fine this time. No looping.
Maybe there was something dirty in the system that was interferring? Maybe I should have tried clearing cache from recovery instead of just restoring to factory first...
Anyway:
Used Cf-root 3.7 flashed PDA with Odin once, rebooted... no baseband..
Used the stock kernel you provided (thank you very much) flashed PDA with Odin and done.
SC-02B 2.3.3 version KE3 Rooted!
(Only really sad thing about resetting to factory was that I hadn't been able to run Titanium Backup without root, so I lost all my Angry Birds progress since the 7th. (T_T) ... some lost spmode emails too, but no big deal.)

My sc-02b rooted 2.3.3 but gps cannot work. I used Angrygps/GPS status/GPS test to connect the satellite, but it's all failed. I also followed the instruction to set up angrygps and gps.conf. Any one know what happen? Is it caused by rooted rom?
Thanks.
Glad you we're able to get root working. Can't think of anything in the root process that would break GPS I rarely use it with this phone sine it has never worked well for me I'll play with it tomorrow.

Stock ROM download?
Anybody have links to this stock firmware? Maybe modem and pit files too? I've been looking all over the net and on Japanese sites but the best I can find is a place to download a pre-rooted KE3.
how's the battery life compared to froyo? Can the camcorder & camera shutter sound finally be muted on the gingerbread update???........
can someone please upload the 2.3.3 firmware for SC-02B here because for some reason my Samsung Kies says "this firmware cannot be updated", so the only solution for me is flashing the firmware via ODIN
Guys, I am stuck in a bootloop after flashing latest CF-root then flashed back original kernel. How can I fix it without reflashing the whole kernel? I have tried flashing the original kernel provided by Dejanet many times but to no avail.
hello people, long time no see
I myself got the upgrade to gingerbread 2 days ago, and rooted that evil thing yesterday, using CF kernel
well, as I was expecting, that damn CWM just wiped away my mmcblk0p3 partition (fortunately I have a dump) so some original apps don't work anymore, but those were expendable
odd enough, I don't even have root access when using the shell in recovery, get some segfault at best
bad news is that I don't have the sources for Samsung's version of the kernel, so I'm not even able to make my own recovery-2e
it's very annoying to see all the good work done by the community that we're not even able to enjoy... sigh
Can you please post the sc-02b OMKF2 Kernel? I already update to the latest version. Last time I follow your selotion. Is worked well. Thanks !

FAQS/Guide/Additional Info For Rooting S2 - High level summary

I rooted my S2 a few days back... there is a lot of info in the forums but spread all over the place and it took quite a long time to find the specific answers to some of the questions i had. Thus I've done a short form guide to help anyone looking to root and give them a bit of extended background and *hopefully* reduce all the copy threads/posts in the forum.
NB/ I'm no android expert. Please don't flame if something i've said is wrong. Let me know/PM me and I'll change it. This is only meant to be high level info!
1. What is rooting?
http://en.wikipedia.org/wiki/Rooting_(Android_OS)
2. What are the warranty implications?
Warranty is void BUT you can return the phone back to *stock* (standard manufacturer ship state) so, as long as you don't bone anything in the root process you can get still get warranty returns.
3. What is [recovery]/[kernel]/[rom]?
Your samsung device memory is separated into different partitions to load different parts of the software to make you device work.
http://www.villainrom.co.uk/vBwiki/index.php/Glossary_of_Android_Terms
Typically you have the kernel partition which tells the device what to load on power on), you have the system partition where your ROM (main operating system is loaded) and you have the recovery partition which allows a user to access and write to the system partition (i.e. load custom roms).
Only difference on the galaxy s2 is that the kernel partition and recovery partition linked. What this means for you is that if you change the kernel, you also change the recovery.
4. What is stock [kernel][firmware]?
http://forum.xda-developers.com/showthread.php?t=1125282
Essentially the stock kernel is the original Samsung kernel shipped on the device (split into many different variants subject to location, sub model, carrier, date etc...) and firmware essentially is the kernel with the Samsung Rom.
5. My current kernel is KG*|KF*...n, can i install any other stock kernel? What are all the different stock kernels? Can I install one over mine?
http://forum.xda-developers.com/showthread.php?t=1075278
Yes you can use any Kernel from any country as long as it is for SGS2 with the correct hardware
Check the models are the same.
6. What's the difference between Cf-Root and Clockworkmod and which do i want?
CF-Root is simply a customised version of the clockwordmod recovery. It still functions the same but cf-root has it's own app for making direct recovery calls from within android as CF-root doesn't function with Rom manager, where pure clockworkmod recovery does work with rom manager.
As far as I'm concerned, it's a question of whether you want to use Rom manager really?
7. How do I root the samsung galaxy S2?
All I will say is..ENSURE KIES IS NOT RUNNING IN SYSTEM TRAY OR TASK MANAGER. KILL THE WHOLE PROCESSS TREE IF YOU FIND IT BEFORE DOING ANY ROOTING!

You can also use the root toolbox method for some stock firmwares without having to flash the recovery:

8. What is superoneclick and what is odin? Where do i get them?
Odin is a flash utility to allow you to push a kernel to your phone from your pc.
Superoneclick is a flash app that will root your phone from your pc.
If you don't want to use superoneclick then simply flash an unsecured kernel (i.e. CF-Root) using Odin and you'll get root already.
Look in the kernel posts and you'll find latest versions there.
9. Can i still get OTA (over the air) updates to my stock rom eventhough I've rooted?
you can update via Kies and root again. Kies wont detect if your phone is rooted or not as long as you are on Stock firmware.
10. How do i get back to stock (as if nothing has ever happened to the phone/factory ship)?
http://forum.xda-developers.com/showthread.php?t=1075278
Flashing a full stock rom and kernel (firmware) using odin will remove everything.
11. What is this yellow exclamation mark and how do I get round it?
Whenever you access the download mode, and write a new kernel, your phone will know you've changed the kernel. The exclamation mark is simply a flag for samsung to easily know whether you've messed with the kernel on returns. You can easily get rid of it by using a jig OR re-flashing the stock kernel following an initial root...then re-flashing the zimage from the CWM image. - Jig is far easier and quicker though.

12. What is the custom binary download counter and how can I restore it?
A counter living in the kernel to record the number of times you've changed the kernel. Only way to remove it is to get a usb jig...
13. What is a jig and what does it do?
it's a little usb plugin from ebay then puts the phone into download mode (even if you bricked a kernel update) resets the kernel counter and removes the yellow exclamation mark.
Simply boot off the phone. Plug it in. The screen will say something like 'Erasing boot information'...then unplug it and re-boot. Very simple.
A jig is a cheap and essential piece of hardware that everyone rooting should invest in!
14. What is download mode and what is recovery mode and how do I access them?
Recovery > enter recovery with the key combination of Vol Up + Home + Power
Download > Accessible on all phones, regardless of kernel via Vol Down + Home +

16. Once rooted I can install custom roms, but can I overwrite the kernel?
Yes, so long as the kernel is compatible with the hardware and in some cases the rom.
17. I've rooted and put CF-Root XWKF(...n)...But I want to put a different kernel on and still have the CWM recovery?
Simply flash the CF-Root over the current CF-Root. However if you are updating a major version (i.e. CWM 4 to CWM 5) just check on CF-Root's thread first.
18. I've pwned my device? What do I do now?
Get a jig to put back into download mode and then flash the original stock firmware.
19. My device is sim locked and/or full of carrier apps? How can I get rid?
To get rid of carrier branding and apps simply flash a different firmware/rom that isn't branded from a carrier. See questions 4 and 5 above for lists of the different stock firmwares.
To get rid of the sim lock you have two options:
1. Root and then use one of the apps from market place (mixed success across the boards); or,
2. Extract some data from your phone in hex code and try and calculate the unlock code yourself.
I bought mine sim free so not done any of this but a quick scan of the forums turned up these two posts which may be useful.

20. What is a 'cooked' rom?
Cooked roms are just roms that someone has made based on the stock rom with slight high level changes. They are different from developed roms such as Cyanogen or Villainrom which receive significant low level modifications and developments.
Check out the Rom kitchen project which when released in stable version will allow you to build your own rom on the fly and select all the apps etc.. you want in it: brilliant example of the benefits of Android!
http://www.romkitchen.org/beta/index.php
21. What is CSC and how do i change my ROM CSC?
CSC = consumer software customisation. The file contains the software packages specific to that region, carrier branding and also APN settings for data connection, SMS, MMS etc...
Three ways to change it (NB it will wipe your device!):
1. Flash a multiCSC ROM and that use CSC Select from Market;
2. Flash a multiCSC ROM and type *#272*Device IMEI# into the dial pad and selecting the csc of your choice;
3. Flash a ROM using ODIN, then flash the desired CSC separately using ODIN.
22. Do you just install Rom over an existing?
Some people do and 9 times out of 10 it works, however I personally boot into recovery, wipe all data/factory reset and wipe Davlik cache > then power off > boot into download mode and install the new rom as above. Best way to ensure a 100% clean install.
23. What is the best way to go from Android 2.x to Android 4.x (Ice Cream Sandwich)?
I struggled trying to get Titanium to quickly and efficiently migrate my data (I'm sure it's very possible but I didn't have the time nor inclination to work around it) therefore I just restored my apps data after manually installing the apps from the marketplace. Once you have a stable working phone on ICS future titanium backup/restores are easy as normal.
24. Titanium Backup? What's the difference in app colour?
Menu => Legend;
Green = App - with data that you should backup;
White = App - should be fine to backup;
Red = System app/service - Wouldn't backup as typically installed by default.
Other tools apps that will be helpful are Titanium Backup (from Android Marketplace https://market.android.com/details?id=com.keramidas.TitaniumBackup&hl=en) and also get a Dropbox account (for free) from Free 2GB Cloud Storage from Dropbox as Titanium can sync to Dropbox.
25. Anything else of note?
Other tools apps that will be helpful are Titanium Backup (from Android Marketplace https://market.android.com/details?id=com.keramidas.TitaniumBackup&hl=en) and also get a Dropbox account (for free) from Free 2GB Cloud Storage from Dropbox as Titanium can sync to Dropbox.
Also slightly linked, if every you want a good UK based hosting for blogs/web/dev - I couldn't recommend TsoHost enough. They are the best hosting company I've ever worked with! Unlimited sql databases and PHP setting modification! If you want 10% off all hosting packages use the code 'wibbsy' at checkout!

New OTA update today

Hey guys, thought I would make a discussion thread about the new update today for the Sprint S5's. Looks like todays update was just over 200 MB. I don't know if it affects the latest chainfire root yet or not.
But yeah, make your stock S5 search for a update and you should find one waiting.
I've noticed:
The Android Security Patch Level is now December 1, 2016
Software version is now G900PVPU3CPL2
Do we know how long Samsung will continue to update our phone OTA? I appreciate that we still have support. It's not so bad being 1 month behind in security updates since even with security updates we are still vulnerable to 0-day exploits anyway.
Does anyone have a copy or link to this update? I want to see if it helps with signal on nougat based roms.
Thanks in advance

The best way to actually try and get this is through Kies or SmartSwitch apps. Sam Mobile does not have this, and it would be, about another month from now, till they even have it... Been there too many times looking for this so call update.
I know that is does state 01dec2016 security update. I also know, that Knox is added to (at least, all Knox is added data (Kbs, not Mbs) I also believe, they (Samsung, tech side phone updates) have added more apps for Knox. However, we don't have anything that is related to these new updates. heck 2 of them, state they have DATA. Through the stock app manager, you have an option, to erase this, because it is not installed....
not sure if this helps you find what you are looking for. ...
( me 2cents on this),... Why extra apps and data../. Why do we have to download a complete new Stock Rom, when we already were stock anyway ???) (Me dog did a real number on the phone. had to be a good eBay and Amazon shopper... Completely rebuild my S5.
Wondering if the S5 will be having A real update, such as 7.1... ??? !!!) we S5, was not on or in the press release early this month, regard the Samsung, Android updates... 7.0, 7.1 NOUGAT !!!
I certainly believe that they will in time update the S5 to 71 Nougat
This may just be a hunch but I have a feeling that if the Note 8's don't blow peoples faces off that the S5 probably won't be seeing Nougat officially (from Sammy).
Well there's a new update today for me anyways. This one is just over 27 MB's. 2 new updates in one month!
The new software version is called G900PVPS3CQA2
New antutu score updated.
It's very unlikely that S5 will receive an official N OTA from any carrier(or any msm8974, for that matter) as Qualcomm had planned 'no official support' for msm8974 past M. It was already very late in the cycle for M, and may not have made it onto the list for M had the msm8994 sucked less.
Does anybody know if we are still able to root our phone model with this new update?

I don't know for sure myself, as I have not gotten the update bring on aftermarket firmware. But I would imagine if you flash twrp and apply the latest supersu, it should work. I know that's how I did it with the cpk1 update.
Someone please correct me if I am wrong. I don't want anyone bricking their device based on what I've said.

Yes.. I did
I ran into some issues and factory reset, deleted my Internal Storage, and then ODined PK1 Stock onto my Sprint S5. I then got a prompt that G900PVPU3CPL2 update was available. After the phone restarted I was then prompted to update to G900PVPS3CQA2 After that one installed and restarted.. I successfully rooted using CFAutoroot and then put the latest TWRP Recovery on.
Now.. what screwed me up is me trying to put a 7.1.1 Rom on (LOS and even Resurrection Remix). Phone froze and would not allow me to enter any info in or select Wifi. When it did.. I had ZERO signal/data. I then re-odined.. PK1.. without the updates, rooted, and Twrped, then flashed the 7.1.1 (LOS and RR) with no problems. Made back-ups of both (within TWRP) and was able to Restore all three at will. I am currently back on the STOCK/ROOTED w/all updates including the QA2.. as I didn't feel like doing the customization of the 7.1.1. Roms with the game (SuperBowl) getting ready to come on.
Personally I like the Stock- Rooted -Updated- Twrp config as the only thing that bothers me is the heading theme being that Samsung Aqua blue. If I could theme it.. I might stay with it

Thank you for the info!! This is what I wanted to hear!! Someone who had the newest update and then went into detail of what they encountered. Thank you again!! Much appreciated!!
You can always see the latest official stuff for our phones here: https://www.sammobile.com/firmwares/database/SM-G900P/SPR/
The only way we'll ever see Nougat on the S5 is via rom ports, or CM14/CM14.1 Official, which is supporting the S5.

No problem. After using the STOCK/ROOTED MM version with all the updates , I have decided that I really am just gonna stay on it. It is smooth, fast, and has all the things I need. I killed Bloatware so outside of the pull-down bar being aqua blue.. and background being white I'm very content.
Anyone know of an app for rooted phones that will allow me to rectify those things?

@cmicasa the Great, I keep getting a failed when using Odin, CFAutoroot, KingoRoot, KingRoot, and even when I try to use TWRP. I also read somewhere that I would have to unlock the Bootloader in order for this to work? Do you mind sending me a message in PM about how you did your rooting? If you don't mind sir. Thank you again for your time and assistance.

This is everything I did including putting PK1 on my phone, letting it then upgrade to G900PVPU3CPL2 and then update to G900PVPS3CQA2 After that one installed and restarted.. I proceeded to Root and put custom recovery on. Because U will not get the OTA updates once U root
Here are my steps Len:
1) First make sure U have the ODIN 3.10 or above> Links are here SamsungOdin or here Odin Download
2) Then go into Download Mode by pressing the "Volume down +home and then Power buttons" Once device boots hit the volume up button and Android dude should appear
3) open ODIN (I used 3.10) and plug phone to computer.
Load the PK1 tar in the PDA Slot, put your phone in Download Mode (power off, hold Vol Down, Home, and Power), and connect your phone to the PC. (I checked F.Reset and Auto Reboot)
Then after that is successful run CF Auto Root or whatever root injector you have in the PDA slot again. Once that finishes (wait until Odin tells you it was a Success before doing anything), get ROM Toolbox or something of that nature and remove any app with Knox in the title or that has the Knox symbol.
Load your phone into Download Mode one last time and then put whatever recovery you have (I use TWRP, make sure you grab the .tar format instead of the zip) and put that in the Bootloader slot in Odin. Then you're good to go, rooted and custom recovery, sky's the limit.

LOL.. no issues. Definitely go to those bottom links. They even have pictures. Be careful though.. I tried to experiment and see what checking the "Nand and Erase" in odin.. and damn near bricked my phone. Had to get PIT file and rebuild. Working smoother than ever now.. and like I said.. I'm sticking to Stock/Rooted and Xposed

So just to clear, there is no need to unlock the Bootloader? Also, if my phone has a password, does it need to be disabled? I.e. lock security feature such as creating a pattern in order to unlock the device to use.

I'm confused on that. Your phone will be booted into DOWNLOAD mode during the time of ODIN. Your Password will be inconsiquential
