Cm 9.1.0 on xperia min pro mango - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

Hi
This is the first time I will be trying out a custom rom. Basically I would have just tried rooting stock rom but I want to go a little further. So I have picked cynanogen mod jellybean based rom.
I found the instructions here
https://wiki.cyanogenmod.org/w/Install_CM_for_mango
So before I start there are few questions I have which I would like some help with.
1. The last step of installing from zip says to use Cwm if using cm 11 and using cyanogenmod recovery if using cm 12 or newer. But the latest stable is 9.1.0 so what method to use ?
2. Does kernel mean boot.img?
3. Will I ever be able to get back to stock if I wish in future ?
4. I am currently on stock 4.0.4 is that good enough to start unlocking bootloader and flashing cm 9.1.0
5. What other issues can I expect ?
6. Should I wipe dalvik , user data and all that before I start with the zip ?
Apologies if some questions are stupid

Anyone with some pointers ?

@rajdeeprath
6.) Yes.
4.)To install CyanogenMod or to flash any kernel ,you will need to unlock bootloader.
2.)Yes. boot.img = kernel.
1.) The recovery is in the boot.img so ignore that instruction
3.) You can just go back to stock ROM by flashing FTF.
5.) Yes you will. Check Bugs and issues in relevant thread for details.

[Q] Important Questions on Flashing Custom Roms on Xperia Phones

Hi , I want to ask some question about flashing custom roms like cyanogen mod on xperia phones
Currently i have Xperia ray with unrooted gingerbread 2.3.4 , 4.0.A.2.0.42 firmware
I want to flash cyanogenmod 7 and my questions are --->
[1.] How can i unlock boot loaders without messing up DRM ? bcoz i heard after unlocking boo loaders update service and some apps wont work.
[2.] How to re lock boot loader in order to get warranty back ?
[3.] Will i need to root my phone in order to install CM7 because , in cyanogenmod wiki they not mentioned root, but i think i need to root my phone
If yes then can i use "Xperia 2011 Easy Rooting Toolkit" to root my phone running on gingerbread 2.3.4
http://forum.xda-developers.com/showthread.php?t=1320350
[4.] how to install full functional clockworkmod recovery on xperia ray ?
[5.] While installing cyanogen mod after flashing boot.img , will i able to make backup of my stock rom ?
and how to restore it even i bricked my phone ?
or is it possible to flash ftf firmwares anytime using flashtools, or wotan . is there any official firmware tool for sony phones ?
and how to get official firmware in FTF file format
[6.] When i successfully installed cyanogenmod , will i get all option to install another custom ROM over cyanogenmod (i.e. CWM recovery and rom manager)
No developer replied my questions , after hours of research i found answers
[1]. http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/
[2]. re-locking bootloader is not possible this time for xperia ray , sony will solve bootloaders issue very soon , then we will not need to worry about this, although we will lose warranty
[3].no need to root your phone , it is like installing ubuntu on windows without knowing passwords
[4]. fxp made CWM for ray but this time it only works with cm7 and MIUI, there are some experimental kernels with cwm are available but i dont recommend them
[5]. of course you can make complete backup of stock rom
to restore follow this = http://forum.xda-developers.com/showthread.php?t=1382088
you can also revert to stock using flashtool , follow this = http://androidflip.com/how-to-install-android-2-3-4-gingerbread-update-on-xperia-ray-st18i/
[6]. definitely you can flash any custom / stock rom over cyanogenmod
maybe u can try my tutorial, but that's language indonesian, u use google translate dude, hehehehehe....

[Q] cyanogenmod 7.1.0.2 & cyanogenmod 7.2

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

Chinese Galaxy S2 (I9100G)

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.

dont worry about the csc means really dont worry, every official rom, custom rom, comes with csc. some of them have multiple csc.

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

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

[Q] Huawei ascend y300 cyanogenmod

Hi!
I was rooting my phone and flashing recovery by tutorial on thumblr with bootloader unlock code from huawei.
I had flashed TWRP because I did all the same as in this tutorial. Today I want to flash on my phone cyanogenmod rom from modaco for example (write "huawei ascend y300 cyanogen mod" in google ).
But if I'm flashing it by TWRP it isn't working (when I'm flashing it there is an error). I have read that I must have CWM to do it, but now is the problem - how can I remove TWRP and install CWM? (Rom manager method isn't working, and when I flash CWM by TWRP it isn't working too). And when I flash CWM with unlock tools from thumblr recovery isn't working.
What can I do?
Sorry for my bad English And sorry for post without links to pages I was writing about but "clever XDA" blocked links for new users :/
If you flashed TWRP Thru Fastboot just flash A CWM image as you would flash A TWRP image
Sent from my HTC Desire C using xda app-developers app
it's working now
I've downloaded wrong ver of rom, the good version works with TWRP. Now can you give me good kernel working with CM 10.1?
And which one of this roms is the best in your opinion? And without video playing and recording issues (artefacts).

Hi...could you help me too??
rootet my y100-0100...so i´m looking for a good costum rom but dont know how to flash it
greetz Marc
I have a y300. Can someone help me step by step how to update with cyanogenmod plz
Greetings,
I'm sorry if I'm posting this on a wrong place but I couldn't find a topic describing my problem.
I have Huawei Y300 for a few months now, and recently I installed Cyanogenmod 11 (Kitkat) on it (Root + Clockworkmod Recovery + KitKat + GAPPS).
The look of this ROM is fantastic (compared to the stock) but the performance is terrible (lag, restarts, app crashes...).
Now I would like to downgrade to Cyanogenmod 10.2 or 10.1, hopefully to get more stable and overall better performance.
Here is my procedure:
- I downloaded cyanogenmod 10.1 with gapps and placed it on my SD card.
- Entering the recovery I did a complete wipe/factory reset, formated data, system, cache, dalvik, everything!!
- Finally, I tried to flash new 10.1 but without success. As soon as I "click" on the file I want to flash, several lines of code appear and everything stops returning me to the recovery menu (later today I will upload a screenshot).
I've read on some forums that the "old" kernel install is necessary before trying to downgrade KitKat.
If anyone has the advice/sollution for me, I would appreciate it!

Do I need custom Kernel for this ROM?

Hello
I'm new to the whole android development
I've had my S2 for some time now and you can tell what I'm dealing with when you know I have the stock rom and haven't tried rooting it
I found this "pound rom" here: http://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-pound-rom-t2535113
there is no "Steps" tho that I can follow
as this will be my first ever time
can someone be kind enough to tell me If I can root my phone and flash this rom using any tutorial out there?
or do I need different kernel? cause it says this in the thread: " Need to flash this ROM with a cm10.2 or newer kernel for best results. "
hopefully this thread isn't against the rules of the forum

first it is not against forum rules
second it means you just need to have a cwm version 6.0.4.3+ which you get in cm10.2 kernel so flash cm10.2 first reboot recovery then a full wipe and the install pound rom
root your phone - http://www.youtube.com/watch?v=OOaTscV92gU ( make sure you are running official jelly bean 4.1.2 xwl.x.x )
after rooting follow this - http://forum.xda-developers.com/galaxy-s2/general/cwm-kit-kat-compatible-t2546597 ( follow this carefully )
after completing the above two steps , you can flash the rom after you wipe data , cache , dalvik cache ... flash the rom and its respective gapps and reboot system .
if you want a kernel , you can flash it after you install the rom you want ( just make sure that is the kernel compatible with the rom and its android version )
feel free to ask anything regarding to galaxy s2 i9100 and you are in no way breaking any forum rules so ask any thing you do not understand ..all the best and happy flashing
a tiny warning after flashing kk comp. cwm
reboot to "recovery" not to system
sometimes i can be missed by newbies like me
