Hey,
i have a Sony Xperia Sola with the Firmware .10 and i wanted to know if there is any way to flash directly from this firmware to a custom rom, and is it possible to backup my things such as SMS history to get this right over in the new ROM?
Thx for all your answers.

You can backup all your data using Backup&Restore app.
To flash a custom rom you need root access and cwm (Make sure you follow the instructions carefully. Also, don't use cwm from another device except sola; Some root methods are universal but you have to take a look if they support sola and ics too)
Once you root your device, you can install cwm.
Once you installed cwm, you download the rom you want to flash (always be sure that's is for sola and not for other devices) and you flash it via cwm (to enter in cwm, press the volume down button once you see during the boot the Sony Logo; You have to press continuously the volume down button for 4-6 times.)
Before flashing the rom, in cwm, you have from the cwm menu, to wipe cache, dalvik cache(advanced menu) and personal data.
Notice also that if your bootloader is locked, you can only flash roms based on ics and gb, not those based on jb. (unlocking the bootloader, you will make you loose your warranty).
For any further help let me know.

I did unlock my bootloader and root my phone. But can i flash custom roms with my .10 firmware, because there are some newer builds available?
MfG RammsteinCyan
Yes, you can.
And if you want new build .54 look in stickies for link. It is tft file which you can flash with flashtool.

Lots of backup apps on Google Play also if it's not a stock based ROM you are going to flash.
Ok thx y´all, but one last question. Can i flash CyanogenMod from FXP with my old firmware?

Hey
Currently have a rooted Xperia Mini Pro on 2.3 Gingerbread but it seems the official ICS 4.0 update won't be coming to my SI number so I have a few questions. I have decided to install a custom ICS ROM on my phone so would like it to be as fast as possible and very stable. So got a few questions for you.
My phone is rooted, do I flash Clockwork Mod onto it and then clear the data etc and flash the new ROM?
How do I unlock the bootloader and can I relock it later? Any easy method? And if I need to do this, do I do it before flashing the recovery?
I have apps installed on my SD Card. I know the ones installed on my phone will be wiped and I can re-install those few but will the large games and apks installed on my SD card be wiped too? Or will they still show up in the menu?
Do I flash the kernel that I'll need the same way as the ROM too?
And finally the most important question: which the quickest ICS ROM for the SK17i?
Thanks a lot in advance
There is 2 ways to unlock the bootloader, one official and one non official. I used the official http://unlockbootloader.sonymobile.com/ the other one you have to find on the forum. Both is possible to relock bootloader by flashing a ftf file thru flashtool.
Kernel is flashed thru flashtool and the rom thru cwm thats usually included in the kernel.
Apps on your SD card will not show on the new custom rom as the phone doesnt know that you have them installed so you will have to reinstall (or use titanium backup).
First of all I tried the official ICS on my SK17i and I didn't like it, it's alot slower than the GB with no super feauters that deserve it
I am now using the MiniCMSandwich Lite ROM. IT'S SOOO great and working very will. You can find it in a thread here.
Follow the instruction in the thread.
If u unlocked bootloader u can relock it but if u decided to unlock it follow the testpoint method not the official one because it's better.
Anyway .. Installing the official ICS or th ROM I told u don't need unlocking bootloader so don't unlock it.
If u want to root ur ICS u have to read that before Updating to ICS

Right firstly I decided to attempt to unlock my bootloader. It turns out for some reason I cannot unlock it (says not allowed in the menu). So suddenly a lot of the good ROMS are out of the question.
I have decided on the below ROM as Tayyar states that I don't need an unlocked bootloader. I know how to flash the ROM etc but how would I flash the Kernel? Or would it automatically flash with the ROM? I remember reading somewhere an unlocked bootloader is a MUST to flash the ICS Kernels hence my question
The official update has also not been made available for my phone and I doubt it will be so I will stick to my current version and flash the ROM now
About the apps on the SD Card, how should I go about it then? Should I get Titanium Backup and then do what with it? I have quite a few apps, it would be very annoying to need to re-install all of these.
Thanks a lot
Since your phone is rooted, try editing the region codes/CDA strings in /system/build.prop to a CDA code/SI number that has the ICS update. I did this myself when I reflashed my phone to get root on GB. I connected using Sony Update Service and was able to get stock ICS customized for my country using "CUSTOMIZED PH WORLD I 1254-1952"
What I changed was the CDA strings inside:
ro.product.name
ro.build.fingerprint
ro.semc.version.cust
You do not have to replace the whole value, just the XXXX-XXXX CDA string you already have there.
More info on these XDA threads:
[SOLVED] force update by editing build.prop, Also: [WIP] list of CDA strings!
Here's a list of available WT19 CDA codes for different countries/regions.
Credits go to original posters.
Titanium Backup is always a great app to use. Only caveat is, you might want to manually restore apps instead of doing a batch restore; some of them might not work with the jump from GB to ICS. Also it would cause a lot of trouble if you try to restore Contacts Storage from a GB ROM to an ICS ROM. Just stating my personal experience

Kernels can only be flashed with an unlocked bootloader. Kernels get only flashed via fastboot mode. A cwm flash is not possible at the moment.
You can flash custom roms via cwm. Your bootloader is locked, so you have to look that your choosen rom is compatible with your bootloader.

My friend, ICS for Xperia mini/minipro sucks.. Its was slow compared to GB. I've tried all the tweaks, hack and other bullshits.. now i am back to GB. and i am very happy i did. But if you really want ICS, then Minicms/CM9 is the best choice.
Guys, i have Xperia Sola ICS stock rom with root. I downloaded GB 184 for sola.
1. Can i downgrade to GB without unlocking bootloader? (with flash tool for example)
2. Can i flash custom ROM on my sola wihtout unlocking bootloader? (with some software)
And if so can someone guide me to how can i do it, thread may be?
Thank you

1. Yes u can, with GB ftf file.
2. If u think on ROMs like CyanogenMod ROM answer is no, u must first unlock ur BL.
1. Of course u can, just download the file and flash it with flashtool
2. Some custom rom need unlock bootloaders to be installed, but another rom no need that.
I think if u want to install more custom rom, mod, root and etc, unlock bl is the best way

Guys, thank you very much. I succesfully downgraded to GB official stock ROM.
Now my last but very important question is - i dont like GB and i still dont like ICS (i downgraded only because of better battery life in GB), but i want to test some custom ROM (like AOKP rom posted in Sola section).
As much as i red i can not flash this ROM without unlocking the bootloader and installing CWM on my phone, is that right?
Actually the question i wanted to ask was - if i unlock bootloader can i flash custom rom with Flash Tool or i can flash only with CWM (which i dont know but i dont want to use)?

Hey guys,I own optimus one and I m used to rooting and stuff but my brother owns xperia mini pro so I need to install cyanogenmod (9 or10) whichever is stable.I had gone through various guides and stickies yet I want to be dead sure that I don't mess up my brothers handset. Its kinda new coz bootloader needs to be unlocked and also kernel image needed to be flashed separately unlike in optimus one.
Now I want help of you guys in the following manner like:-
1. My brothers mini pro is on ICS 4.1.B.0.587 and the rooting tutorial provided here for the said firmware
http://talk.sonymobile.com/thread/41119?start=0&tstart=0 is not clear to me coz it says that first I need to install some kernel [only mini mentioned here] then next I need to flash another kernel according to firmware. Can someone explain what is being done in this and why rooting is so complicated in this.
2. Certain ROM's say that you need to flash kernel first using flashtool
My query is that all ROM's that I flashed till now on optimus one included kernel and I only needed to flash ROM zip through cwm.. So do I need to flash kernel everytime I flash ROM!! and isn't there flashable zip for kernel too!!
3. FXP ROM's do not contain things like what's working and what's not, it only has issue tracker so it become difficult for new comer to know the bugs in ROM. Can anyone tell me the least bugs cm9 & cm10 ROM and what are the bugs present.
4. Lastly, should I proceed like this!!
i. Root device (though method isn't clear to me)
ii. unlock bootloader
iii. install cwm (I guess I can do this using flashtool)
iv. backup current ROM along with kernel (for future use,I know its optional)
v. flash kernel using flashtool
vi. flash ROM through cwm.
I m a quick learner and I just need some guidance on this new device (double checking coz its my bro's device) . Looking forward for support. Thanks

You needn't root first if you want to unlock bl, just unlock bl and flash a custom kernel (in most custom kernels cwm is included).
Backup your rom and install the rom...
hmmm....
1. Unlock Bootloader........
2. Flash Custom Kernel (all custom kernel is per-rooted and have CWM).......
3. Boot into CWM and Flash CM9 or CM10 (factory format/wipe dalvik/cache).....
4. Boot into Fastboot And Flash FXP kernel for CM9 or CM10.....
xperia phones aren't like sammy, lg or htc where recovery is a separate partition from kernel. in fact, by default xperia phones doesn't even have "stock recovery" like on other phone. by that we integrate cwm in kernel ramdisk.
and to answer the question:
1- flash custom kernel mean't for your phone only, never ever flash kernel intended for other phone. and its done via fastboot and should be flashed before flashing rom.
2- like i said u can't compare xperia phone with other phone like sammy etc, its different. kernel must be flash via fastboot.
3- for cm10, bugs that i notice is slow accelerator, but fixable with some text editing, and non working front camera for lww and minipro.
4- should be like this, according to order:
- unlock bootloader.
- flash kernel via fastboot.
- boot into cwm.
- backup rom if u want.
- wipe data, cache and dalvik cache. don't wipe system partition or u will get error when flashing rom later.
- flash rom, and gapps if its cm/aokp/pa rom.
- profit :good:
thank you guys.... this made me clear...
one last thing :- which kernel should I flash on stock 4.1.B.0.587 which is pre rooted and have cwm after unlocking bootloader.I mean the one compatible with above firmware and also do I need to do anything with baseband or will it be compatible. After this m ready to enter the custom xperia world
Remember to backup your stock rom before unlocking the bootloader as everything will be wiped clear.

hi everybody!
I need an help. Sorry for my bad english, I'm only 16 and I'm Italian.
I have an Xperia Mini, it's my first android phone, so I'm not very good at android modding! I downgraded it from ICS (Official) to Gingerbread (4.0.2.A.0.42 build) and I rooted it. Then I installed ClockWorkMod recovery. I don't have an unlocked bootloader, but I want to flash a custom ROM based on gingerbread. If I flash it, can I go back to stock rom with CWM's restore function? And If I can't, can I use flashtool to flash it (I have the .ftf file that I flashed for downgrading)?
Thanks very much.
Welcome to our forum
You can flash a gingerbread custom rom for locked bootloader with cwm, but be sure it is for locked bootloader!
If you take a backup in cwm, with backup/restore -> backup before you install the custom rom, you can restore this backup to go back to stock. Flashing the stock ftf will also work, you have to decide if you want to restore or flash, but if you take the backup in cwm it will backup the whole firmware with all apps etc :good:
Thanks! :good:
But do I need to flash a custom kernel? Or can I keep the stock kernel?

Normally it should work, but the problem is there's not specified if it is for locked or unlocked bootloader. It's stock based so it could work on locked, but it is recommend to flash a kernel. You could try it, but it could be you get a brick
When it's bricked, (mostly) you can't boot in recovery so you have to flash the stock rom with flashtool
Another little advice: If you install an ics custom rom on a gingerbread phone it could end in a brick. I had this when I was on locked bootloader, so I updated to ics (while keeping root, how to do this is in my rooting guide) and installed it again.
You can try an ics custom rom on your phone running gingerbread, just install it. But if it won't boot, flash the stock gingerbread rom and update it with root to ics
Ok. But before installing a rom, I have to do a full wipe, and wiping all will delete the CWM recovery?
I think I'll first upgrade to ICS officially. Can I use pc companion? or I have to flash the .ftf file of the stock 4.0.4 firmware with flashtool?

1.) make nandroid backup
2.) factory reset/wipe data
3.) wipe cache/partition
4.) format system
5.) wipe dalvik cache and battery stats.
6.) flash ROM
7.) flash supersu fix, there are lots of links out there just incase you have problems with root. this will solve your problem if u have locked BL
8.) if you lose CWM, you can use led deletes x-recovery tool to install cwm after you boot your rom
BUT TAKE NOTE THAT THERE ARE CERTAIN THINGS YOU MUST DO IN "SOME" Custom ROMS like Hasa(flashing lockscreen after 1st boot)
MAKE SURE TO READ THE THREAD's INSTRUCTIONS FIRST

hi all,
i tried the methods mentioned in the links pos9ted earlier to upgrade the phone to ICS first using SEUS and hen root it. unfortunately it did not work out. i can confirm that the steps mentioned were done correctly. what i have done is have downgraded to Gb and then rooted it. Post that i have installed a custom rom. is there any way i can install a custom rom for ICS now?
AW: How to install ICS based rom on a rooted Mini pro
for most custom roms you need to unlock your bootloader, or look if the rom you like to have is for locked bootloader too. for some roms you need to flash different kernel first. i would suggest you to flash a prerooted kernel with built in recovery. then you can install new rom via that recovery.
For installing custom roms like cm etc you need to unlock bootloader, if you don't want to do that go here and find a rom that does not need bootloader unlock. if you didn't unlock bl, download xparts and install cwm.
for unlocking, go here
then go here find a custom rom, copy zip to sd card, extract boot.img to pc, flash boot.img in fastboot mode of flashtool or fastboot, boot device, enter cwm and flash zip from sd.
thank mihann for the excellent guide.
hope it helped
