Hello to xda-forum's community!
I've bought new unbranded SE Xperia Mini Pro and it's my first Android device. I'm new to this forum and Android phones, but I'm aware of possibilities custom mods provides. I want to change stock Android to cyanogenmod 7.1.0.2 from official cyangoenmod site. But before I'll try all this I have couple questions for you:
1) Should I update my phone's official firmware before unlocking bootloader and flashing cyanogenmod 7.1.0.2?
2) Is there any option to make a full copy of my official Android before trying to flsh new one? I heard about NANDroid backup available in bootloader, but will it restore Sony Ericsson's Android if anything will go wrong?
3)What is the difference between mods and kernels? I assume I will flash new rom (cyanogenmod 7.1.0.2), but what will be the kernel?
4) How can I prevent bootloop problem during flashing cyanogenmod 7.1.0.2? From what I've read, it's a pretty big problem and nobody presented a full solution, in fact there wasn't any help at all. I searched a bit on other Sony Ericsson Xperia's forums, and this problem is not exclusive for Xperia Mini Pro, but appears in i.e. Xperia Neo, Xperia Mini etc. People claim that removing AntHalService.apk from zip archive (update-cm-7.1.0.2-XperiaMiniPro-SK17i-signed.zip/system/app) made flashing new stable cyanogenmod possible. But I don't know what to tkink about removing one of system apps. I have no idea what is it doing and if it's safe. What do you think?
4) Is everything working in this cyanogenmod 7.1.0.2 release?
5) What's the difference between cyanogenmod 7.1.0.2 from official site and the cyanogenmod 7.2 made by freexperia team? It's completely new cyanogen or maybe they're upgrading version 7.1.0.2? Or maybe they're making their own version of cyanogenmod and that's why it's still in development and some things arent fully working now?
I really hope someone will help me. Have a nice day
1) Yes you should update to the latest firmware .62 because the latest FXP106 requires the latest baseband to work properly.
2) Yes, once you have access to CWM, you can backup your rom.
3) I don't understand what you mean by "mod", you mean like a visual mod, like a .zip file you flash in CWM? A kernel is "a bridge between applications and the actual data processing done at the hardware level". People flash kernel for extra function, like CWM, Root, and Overclocking.
4) I never had any bootloop with custom ROMs, you just need to follow the instructions step by step and everything should work perfect.
4bis) Yes the phone is very functional with Cyanogenmod. Screen, 3G, Camera everything seems to works good, at least for me.
5) Freexperia Team makes both versions to my knowledge. 7.2 is an RC version, it has the latest fixes, changes.
Hope I answered your questions. If I were you, since you are new to Android phones, I would not try to switch to Cyanogenmod for the moment. Get used to your phone before doing anything serious (Cyanogenmod requires an unlocked bootloader, meaning you lose your warranty). Read information, threads, on your phone and Android to learn how things work.
I think I'll take your advice and won't try serious things right now. But I have couple more questions, it will be great if you'll answer
1) I see FXP106 requires the latest firmware, but there are some things not working properly in this version (i.e. radio), propobably because it's a RC. So are there things not working in latest stable cyanogenmod 7.1.0.2 from wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Mini_Pro:_Full_Update_Guide? I prefer older release where everything is running than new but buggy.
2) Should I update my firmware to the newest one in order to install cyanogenmod from the above link? I still hesitate to do this because there is no way (at least for now) to root latest baseband .64 and rooting seems to be less complicated operation than flashing new rom.
3) In my previous post I asked about the difference between rom and kernel.
4) There's something I don't understand in the guide I linked. At first I'm unlocking the bootloader. Can I make a full backup of my firmware just after this point? Or should I update the kernel (via step with boot.img) and then make a backup?
5) Is it possible to boot firmware after step with updating the kernel? I mean, can I boot the phone after this step?
6) If I follow the above guide, at which point am I rooting the phone?
I'll try my best to answer your questions.
1) Honestly I didn't try Cyanogenmod much time but the latest FXP ROMs worked great for me, no major bugs and pretty stable! I would prefer the latest release if I were you.
2) Anyways if you want Cyanogenmod, you NEED an unlocked bootloader. That will make the ROOT process easy. First you ROOT your device to get access to recovery with a new kernel then you will flash the ROM. And yes you should upgrade to the latest version for Cyanogenmod.
3) ROM = it's the complete system, think of it like installing the OS on your computer. KERNEL = the drivers that allow software and hardware to interact.
4) Once you unlock you bootloader, you will be able to flash a custom kernel that will give you access to recovery (CWM) and there you will be able to perform a backup.
5) Once you flash a new kernel, it depends. If it's a kernel for stock ROM yes you can boot right away. But Cyanogenmod used a different kernel.
6) If you follow the guide, you are rooting your phone at the moment you flash a kernel that gives you root access.

Hope you enjoy your Xperia Mini Pro! I'm loving mine
1)Yes, you should update your phone to the lastest firmware. It worked for me when I did it
2)Yes there is, after you unlocked the bootloader and flashed a kernel on, in the ClockWorkRecovery Mod, there is a "backup or restore" option to backup the Xperia Mini Pro stock ROM
3)ROMs is the UI your phone will be using for example HTC Sense is HTC Sense UI and Kernel is the driver for yours phone software and hardware to interact and process
4)I tried to flash CyanogenMod 7.1.0.2 and I got stuck on the bootloading screen, I did many methods and such and I couldn't stop the looping. Plus the Official CyanogenMod team has given a statement or a bug fix to fix it. Though CyanogenMod 7.1.0.1 works but has many bugs to fix out, the biggest one is that Vibration doesn't work.
5)The FreeXperia teams works more on the Mini phones then the Official CyanogenMod team because the CyanogenMod team, usually ports the ROM from another phone and then does all the bugs fixes. While the FreeXperia Team, works fully with the Mini and Mini Pro phones, building a ROM around the phone instead of a port. (Thats what I heard, not fully sure)
If your new to the Android community, do not root or flash a ROM without getting to know how it all works. Plus it will void your warranty. Hope all this helps
Hi there
I am a total novice so i apologize if my questions are a completely non-sense.
First of all a really big thanks to the developer who built this amazing and helpful toolkit.
My father is using an S3 European version Orange branded 4.1.2 Android version .I wanted to unlock it so it can work on different gsm carrier.I've installed ALLINONE option(Flashed Insecure boot,Recovery,Root,Busybox,Rename restore Files) Twrp Custom Recovery using the UNIFIED TOOLKIT.Then i used GalaxySimUnlock apk to unlock it.All went smoothly everything is working perfect the phone is unlocked.
Now i have 1 question:
If i'd like to use the official samsung software update because now is not working due to the rooting i am guessing or send the device back to warranty (unexpected undesirable event) I will have to use option no.8 present in the toolkit(Download extract +Flash Stock Rom via Odin).And will my phone remain unlocked OR option number 2-Unroot Option will be enough?(I mention that i didn't yet installed any Custom Rom).
Thank you so much!
The most stable custom Rom available
Going to flash my first custom Rom.Need your professional advice.Which one is being considered the most stable Custom Rom?Which version of Omega Series to be more precise,already downloaded the latest version V42 but read on the forum there are some little bugs I will be very grateful for your help Thanks

What rom best rom posts are banned .
You choose .
No custom rom is bug free decide if the bugs rule the rom out or not .
Later is generally better for any rom build .
Omega is updated very frequently .

I am still new at this stuff, and did research on the forums, but cant find an answer
For example, one of the Roms I want to install had this description;
(http://forum.xda-developers.com/showthread.php?t=2133763)
YOU MUST BE ON THE VERIZON (USA) JB KERNEL(either through dualboot or the leak) TO FLASH THIS ROM
YOU MUST FOLLOW THESE INSTRUCTIONS EXACTLY.
~~~~
I am using Safetrap 3.11, and my stock rom is running just the regular stock that came with the phone (4.0.4) android
(My phone is CDMA too I think.).
Does that mean I have to install a different rom that has a JB kernel on slot 1, and then I can install this rom into slot 2,
does it work like that? It can get a little iffy for me trying to understand rom requirements.

No,you just install JB kernel and then Jb rom on system 2 (if you want) and you´ll still have ICS on system 1.
Be sure that before anything,you do a backup of kernel and cid,so you can go back to ICS if you want.
Here is the very good rom http://forum.xda-developers.com/showthread.php?t=2142593 ,everything is working,good battery life...
Just follow the instructions
I have a Galaxy S2 GT-I9100G (bought in China 2 years ago).
In the past I have changed it's rom to SuperROM#v1.1 found here : http://forum.xda-developers.com/showthread.php?t=1374135.
The current Android version is 2.3.6 (oldddd )
Kernel version is : 2.6.35.7
Baseband version : I9100GZCKI1
I also have CWM-based Recovery v5.0.2.6 for GS2.
I would really like to upgrade to JellyBean.
I have seen a couple of versions here:
* http://www.ibtimes.co.uk/articles/4...100g-android422-jellybean-aokp-mr1-build6.htm
* http://www.ibtimes.co.uk/articles/4...-android422-jellybean-vanilla-rootbox-rom.htm
* http://www.ibtimes.co.uk/articles/4...droid422-jellybean-update-slimbean-build5.htm
and of course all the ROMs here on the site (too much to choose from !)
My question is : can my *Chinese* device be upgraded to JellyBean ?
If so - I have read on some forum threads that I need to somehow get the stock roms first, but I have no idea where to get them for the Chinese device.
Any help would be very much appreciated...

officially yes, unofficially(none samsung) yes
official:
take a look at this: http://forum.xda-developers.com/showthread.php?t=2171269 (thanks to hacbaoklhh for posting this thread)
unofficial (none samsung)
first you need to do the official thing (so you can get the ics/jb boatloader in), if you wish to stick with the official then you're done, no need to continue.
then you need to do this: http://forum.xda-developers.com/showthread.php?t=2113545 flash via stock recovery (thanks to Ryuinferno for his great work)
then you can flash whatever rom you want (AOSP, AOKP, MIUI)
to revert back to original:
take a look at this: http://forum.xda-developers.com/showthread.php?t=1916623 (thanks to Harchaoui for his hard work) or you can do the official thing again via odin, end of story
but i wouldnt revert back to chinese stock rom, we have the best developers and our 4.2.2 has become so stable
good luck

Wow, that was fast !
Thanks so much for the response.
I have 3 questions if you could answer:
1. In your first link it says "Instructions For Flashing ICS:".
Does it mean that is will flash ICS or that I need to have ICS to flash it ?
because I don't have ICS... I have Gingerbread ...
2. Does the process in both your links change the Kernel or the Rom ?
(I managed to forget all this stuff since I last did this 2 years ago)
3. Which ROM would you recommend to use ? (out of the AOPS, AOKS and MIUI)
Thanks !

1. its ok, that's probably just a typo, the android version there is 4.1.2. should state JB. via odin you can flash that and you will have official JB
flashing via odin doesnt care which version of android you currently have
2. the process of the first link will basically put a whole new kernel and rom in your system. you will have official JB kernel from samsung along with official rom from samsung. your version will be 4.1.2. (this is required to get the ics/jb bootloader which you dont have)
the purpose of the second link is to change the kernel so that it has cwm or twrp recovery integrated in. this will allow you to flash mods and roms and all that. but it is not necisary if you are not willing to use AOSP AOKP MIUI. if you'd like to stick with the official and see how it performs then you don't have to do the second link
3. personally i think the simpler the better, i use CM10.1 (CyanogenMod 10.1) <----- thanks to codworkerx, i also like Thinking Bridge http://forum.xda-developers.com/showthread.php?t=2199527 (thanks to Black_Prince for his great work)
couple any of those roms with http://forum.xda-developers.com/showthread.php?t=2251840 kernel (thanks to biagio7xD) and you will have a super fast rom with no SOD

Dont worry about CSC.
every rom comes with its own kernel, if you're refering to step one as in the official then that's the kernel for official and nothing else
the blazing kernel is also for official and nothing else (or official based roms)
the kernel link i gave you last was for aosp aokp based roms

So I am a bit confused now ...
You say 'don't worry about CSC'.
Does that mean I don't have to install CSC ?
Or that I do have to install it, but not worry about it...
also - I understood from your 1st comment that I have to go through the official kernel & rom, before I can put a custom rom.
Did I get it right ?
Because now from your last comment - I am understanding that if I want a custom rom - I can go ahead and just install it with its own kernel, without having to go through the first step of installing the official rom and kernel.

CWM = clockworkmod (this is the recovery integrated with the kernel. you have a few main types- cwm, twrp, official). this recovery allows you to install roms and such. version 6 is the latest. if i'm not mistaken the version you have for gingerbread would be (if you have cwm) 4 or 5.
cm = cyanogenmod (this is the rom)
they are two different things.
let us go through the basics:
what does a ROM have?
it has a kernel (this allows you to do the basic io stuff, it has cwm or twrp >> if custom, or official recover if official)
it has a bootloader (this allows you to get into a specific version of roms), official roms have the bootloader
it has system files (this is the actual rom base, it has all the modules)
it has basic apps (well, these are the apps, dialer, messaging, etc..)
it has csc
it has baseband and ril
let us elaborate a little bit:
your phone currently has gingerbread bootloader. so it is version 2.0+
to use Icecream sandwich you need the icecream sandwich bootloader. 4.0+
different version means different bootloader
this is where flashing a rom via odin comes in handy. it will install that specific bootloader into your phone
ofcourse along with other things, like the kernel, actual rom, apps. so you will have a full 4.1.2 system.
notice: ics and jb bootloaders are the same, reason is simple, the base version of both is 4, if there they introduce a version 5 android then everyone has to get the newest bootloader for version 5 to use it.
it doesnt matter where the 4.x+ comes from, if it is aosp aokp official miui, the bootloader is REQUIRED to run any of those
now your first step is to install the official rom (this way you ensure that you have the proper bootloader, and at the same time you get the official 4.1.2). now if you want to keep the official then there is nothing else to do, if by any chance you need to change csc then the steps there are simple, but it is not required. look up what is csc
next you need to install a kernel that has either cwm or twrp (this way you prepare yourself to install custom roms)
next you select the rom you would like to install, download it and put it in your sdcard
next you boot into recover (notice it is different from the official one, it has many options)
install the rom from the sdcard location
and in many cases you will have to install gapps (google apps, and do not make a mistake and install the wrong one, every version of android has its own gapps, if you have 4.2.2 install ONLY 4.2.2 gapps)
done!
as i mentioned above, every rom comes with whatever that it comes with. a kernel, csc, blah blah blah.
so basically what happens when you flash the custom rom?
simple, you change the kernel (zImage) it has its own and that's what it needs to run, and official kernel cannot run an aosp rom. period.
you put a whole new framework, system, apps, based on the android version they have been developed in.
next if you want to modify things, you can get into themes, installing another kernel, changing baseband and ril(Radio Interface Layer), and so on.
well i hope this helps

and in many cases you will have to install gapps (google apps, and do not make a mistake and install the wrong one, every version of android has its own gapps, if you have 4.2.2 install ONLY 4.2.2 gapps)
done!
as i mentioned above, every rom comes with whatever that it comes with. a kernel, csc, blah blah blah.
so basically what happens when you flash the custom rom?
simple, you change the kernel (zImage) it has its own and that's what it needs to run, and official kernel cannot run an aosp rom. period.
you put a whole new framework, system, apps, based on the android version they have been developed in.
next if you want to modify things, you can get into themes, installing another kernel, changing baseband and ril(Radio Interface Layer), and so on.
well i hope this helps

How to give a "second life" to my old galaxy s2 ? wipe, kernels, roms, repartition ?
So i have my old galaxy s2, and i want to completly wipe everything and make it better.
There are a lot of tutorials, but im really confussed. For example there are roms that require android 4.4 or sth like that. I just want to do a fresh install. I also don't get what's going on with kernels.
Right now it runs old android 2.3.3 gingerbread and it's really slow.
I want:
- Some stable, battery friendly android lollipop rom, with all functions working (like usb internet tethering, wifi tethering, camera and so on).
- Only one partition like in new phones (like in galaxy s5)
- kernel ?
- root
- custom recovery
Can anyone give me some step by step instructions, what should i do first ? I would also appreciate if you could send me links to appropriate tutorials.
4.4.4 any custom without GApps then microG it.. with MOAB and Fdroid. All can be found in the forum.. Cheers.

I assume it's on non-rooted stock ROM (android operating system). Backup all data you don't want to loose, format the external SD card (the one you can take out) if you have one (not required, but a good idea to start from scratch) from settings, then do a factory reset from settings.
Then connect the phone to Samsung Kies (download from samsung.com) and update the phone to the latest stock ROM (See which in your country here: http://www.sammobile.com/firmwares/database/GT-I9100/)
Let me know if you succeed in doing so.
I just installed stock Android 4.1.2 ROM, it's not rooted right now.
Android: 4.1.2
Modem, Baseband version: I9100XXMS2
Kernel: 3.0.31 - 1155032
Build number: JZO54K.I9100XXMS7
What to do next ? I want some good lollipop rom (or kitkat if it's faster), custom recovery and root.
@edit:
Ok, i managed to repartition my device memory and i flashed CyanogenMod 11 (m12) with cwm recovery (compatible with kitkat).
