[Q] cyanogenmod 7.1.0.2 & cyanogenmod 7.2 - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

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

[Q] SK17i, restore latest stock/official Gingerbread?

Hey Folks,
I Googled, I really did, so don't get angry at me...
As many others, I updated my phone to ICS, and found it really disappointing. Laggy, choppy, and the UI was messed up in few places(like getting to favorites in phonebook). Not to mention the annoying notification LED issue.
So, I went and installed CM 9.1 and tried also the CM 7.2.
Didn't like it, decided to go back to latest stock Gingerbread.
What is the latest OFFICIAL GB?
I've seen a thead about 4.0.2.a.62 on XDA forums, but the link to rapidshare wasn't working. I tired one I found on shady site(yeah, I know, stupid), but it had issues with physical qwerty, and I just didn't trust the software of a random site.
Currently, I'm running 4.0.2.a.58, but I'm receiving notification about an update to .62 via the update center in the phone, but it fails to install. (probably cause I put in a boot.img from CM 9.1 package) Also, the notification is annoying as hell. Any way to remove it?
Can someone please point me to the latest, RELIABLE GB rom? Also, is there a way to put back the original recovery image? (working download links and step by step instructions for a noob would be very appreciated)
To sum it up, how do I get my phone to be like a regular, stock phone from SE with the latest 2.3.4 android?
And no, there is no Sony service point in my country, and the vendor previously refused to honor the warranty and roll back official ICS to GB.

Welcome to the forum. Thread moved, please post all your question threads here in Q&A in future.
Also normally common questions can be answered by reading the sticky threads at the top of General like this one as they normally cover all the basics.
Thanks
AvRS

Of course you can't do an over the air update on unlocked boot loader, this can brick your phone!
The latest official firmware is 4.0.2.A.0.62 and for Germany (only?) .69 that you can download as a flashable zip
There is no recovery image, xperia devices don't have a stock recovery
You could flash a prerooted kernel for gingerbread (e.g. rage kernel), boot in cwm and flash .69 :good:

Thank you for the information
Now, is there a tested and working .62 image laying around? I've found one, but it messes with my qwerty, and I don't know where it came from and if someone put in bits that shouldn't be there....
The ones shown here in the forums is 4.0.2.A.0.42... (I have the sk17i model)

[Q] First time flashing Cyanogenmod: Help needed on installing CM10 or CM10.1

Hello there!
I'm a complete noob when it comes to rooting and other related stuff so I could use some help. I want to install Cyanogenmod 10 (or 10.1 if it actually is usable and mostly stable / it is easier or more noobproof to install) for the first time and I would like to know what do I need to know before starting to follow any tutorials for flashing new kernels etc. There are just so so many tutorials for this and I don't know which one I should follow to not brick my phone as I just can't afford a new phone if I manage to brick this one and I just want to get everything out of this phone.
All this Clockworkmod, Odin, Rooting and everything just confuses me and I don't know where to start. If I've understood correct the first thing I should do is I should download some custom kernel as this is something which runs "under" the Android (kind of like bios for computers?) and allows me superuser access=rooting? Then after I got new rooted kernel done I should install Odin or ClockworkMod which acts like a "backup" if something goes wrong? And lastly I should flash in the Cyanogenmod 10 or 10.1 depending which is more hassle-free for everyday use (I'd like to get as much customization as possible for my phone) and has more features and more stable.
My phone model is GT-I9100 so it's the international one (I live in Finland so no Verizon or other model of it.. that much I understand at least) and my Android version is 4.0.4 the 100% stock version of it.
I'm tired of waiting for the slow Samsung people in Finland to get the official Jelly Bean release to be done and I want all that project butter goodness NOOOOOOW. So...
TLR: I have Samsung Galaxy S2 (GT-I9100).I want to get CM 10 or CM.10.1 the noobproofest way possible, can't afford to brick. Can you guide me to a good tutorial with easy to follow orders and up-to-date versions of Cyanogenmod as I don't want CM7, but the latest GOOD Jelly Bean version or just tell me how to do this? I will answer any questions you might have about my phone or anything. I'm not stupid when it comes to computers, but phones are totally new thing to me and I don't want to flash new jelly bean with some random tutorials from youtube as I'm afraid of getting a bricked phone (or missing out some great features from other Jelly Bean releases). I want the best for everyday use, most stable and the one with most customization options version of CyanogenMod Jelly Bean for my S2.
Thanks in advance! I will be monitoring this thread actively so I answer possible questions quick.

I think you're a bit confused at some points.. I assume you're on ICS now. First you have to root your phone by flashing a custom kernel (which gaines you root access) like Siyah WITH Odin. Steps are descriped in enough guides on xda.
When you've rooted your phone, it's best to make a Nandroid back up in Recovery Mode (CWM), you get CWM automatically with flashing Siyah, just in case anything goes wrong.
After this you may choose to flash a custom rom, mostly done with CWM recovery. Steps for this part are almost always written at the instructions on the first post of a rom thread, so read them carefully.
About Project Butter: this isn't fully implemented in CM, so flash the JB-leak from Samsung, or a rom based on it (or wait for the official release).

Yes I'm running 4.0.4 forgot to add that sorry. That clears many things up thank you! Oh... I thought that Project Butter was fully implemented on every 4.1.X ROM. Now I'm having hard time deciding if I should flash CM10 or just wait for the official Jelly Bean release which is supposed to come next month in Finland... I just want my phone to be really, really fluid and I'm not really pleased with this current 4.0.4 and all these unneeded programs like all the Samsung Hub programs.

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

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

[Q] How do I remove Cyanogenmod 11.0 & install this custom ROM

Hi there,
I'm sorry if this has been covered before in another thread but after searching with limited success I have been unable to find a detailed answer, perhaps I'm just a little bit dim & have missed something however.
QUESTION:
After installing CyanogenMod 11.0 [KitKat][4.4.2] by "Gava97" I have found that it is simply not for me. I would very much like to install Destro316's "Proformance" ROM [4.0.4] http://forum.xda-developers.com/xpe...m-4-0-4-proformance-rom-long-battery-t2547481 as it seems much more stable having been based on a stock Sony ROM.
Do I just flash the new ROM over the previous one? Do I return to a stock setup & redo the rooting process? If so, how?
Being extremely new at this android thing, I'm a little stumped as to how to proceed. All instructions seem too vague for me to confidently follow without bricking something. As I said, it may just be that I'm a missing something.
Phone was originally running [2.3.7] when I bought it, though I soon flashed to stock Sony ICS [4.0.4] Firmware version 6.1.1.B.1.100.
I unlocked my bootloader, rooted & installed Clockwordmod Recovery via this tutorial: www(dot)youtube(dot)com/watch?v=V232-3tZddE
I would be very grateful if anyone could fill me in with a step-by-step guide on removing all traces of CyanogenMod & installing this new ROM. Any suggestions for different ROM's are welcome as well, of course.
-----
Bootloader unlocked: Yes
Root: Yes
Clockworkmod Recovery: Yes
Kernel version: Transcendence v 1.1.6
Flashtool Version: 0.9.14.0
PC: Windows 7
-----
I really am sorry if I missed something in my search, I'm very new at this.
I appreciate anyone taking the time to read this & help me out.
Cheers,
Miles

Just follow the instructions on the ROM threat, this is erasing your CM 11, then install your ROM through CWM.
Good luck!

U could Just follow the instructions that included at the ROM u want, that will eras your CM 11, then install the ROM U want through CWM.
Clean Install is required

Woops
Hi everyone!
Sorry for the late update.
So I attempted to follow the instructions outlined in the new rom I was attempting to install and it did nothing. Absolutely nothing. Phone continued to boot into Cyanogenmod 11 kitkat as if nothing had happened.
Now obviously I messed something up, but I needed a properly functioning phone for work asap so I bought an Xperia Z1 Compact just to be done with it. Over the hassle.
However it's been bothering me that I still have a basically pristine Xperia U minus it's software tantrum.
So, how do I go about restoring this phone to the factory Gingerbread and removing Cyanogenmod?
Baby steps please.

I'm by no means an expert.
I follow the guidelines here to flash my Xperia Sola from ICS to a Kitkat rom.

I'm not entirely sure but downgrading should be similar? Fastboot (via flashtool) and flash boot.img. Then in recovery mode, flash the stock Gingerbread rom?

[Q] SGP511 Does running different base firmware under cyanogenmod make a difference?

Hey Guys
Having some trouble with my z2 tab. Might be hardware related not sure yet. Regardless, can anyone tell me if the firmware a sony experia is running before flashing cyanogenmod makes a difference? I am unclear on this being an HTC user for years I know that firmware in HTC land updates modem and wifi drivers etc so base firmware makes a difference. Is this the same in xperia land? Seemingly I have two choices moving forward with my z2 tab as doomlord has stated that there are two firmware versions that are compatible with his root and CWM recovery.
He says:
7.1.1.A.0.402 - v03
17.1.A.2.36 - v01 or roms based on that firmware. Not sure what he means by roms based on that firmware. Can anyone please shed some light?
Thanks

Bump

I am running CM11/CM12 since last summer on my SGP512. No problems whatsoever.
To run CM12, you don't need to install a recovery with a stock kernel. Just flash the CM boot. img via fastboot as described in the thread, it contains the recovery and the kernel.
Note that the CM12 recovery has some bugs, so sometimes the CM11 recovery has to be used. Everything is explained in the CM12 thread in the original development section.

Thanks. I too have been running cm11 and now 12 since may. I am more curious if the base firmware before u load cm makes a difference
