Flashtool V0.8.6.0. 22
Marsilius Boa
The best kernel (my personal opinion) for the 2011 Xperia devices is built by kamarush, a recognized developer of XDA community. I will use this kernel for this tutorial. You may choose any other kernel, but the ROM I am going to flash on the next section works best with this kernel.
1. [OPTIONAL] Perform a full wipe in CWM: factoy reset, cache, Dalvik cache and battery stats
2. [OPTIONAL] Relock your bootloader using this FTF file. That is, turn off your phone. Open Flashtool on your PC. Select Flashmode and browse to the folder where you put the relocking FTF file. Connect your phone accordingly when prompted and done.
3. Flash your phone using the stock FTF file. From here, you can download the FTF file for the Sony Ericsson stock 4.0.2.A.0.62 (the latest version of Android 2.3.4).
If you want to downgrade your phone to Gingerbread 2.3.4, you do not need to root or unlock your bootloader. The downgrading process is very easy and will take only 5 minutes of your time. Just download the FTF file (you will find it here) for your XMP. Download and install Flashtool. Start Flashtool, click on the lightning sign, select Flashmode, then browse to the FTF file you just downloaded, wait for a while, follow the on-screen instructions to connect your phone and you are done.
hi man i have cynogen mob 9.1 installed in my xperia mini pro and i get borred with it so i think to get my real sony system back so i flash the device with ics4.0.4.ftf file and also it get flashed but after unplugging the device from computer and when i switch it on it starts and on screen comes sony after xperia but after these it is again rebooting agin and again and also it is not flashin back man now what i do man please help me
hi there Hafiz bro i read all the conversation about sony xperia ics upgrade etc but plz can u help to tel me can i update my device sony ericsson xperia mini pro sk17i using flashtool from ver 4.2 to 7.2 i have ftf file???
Hafiz I like the details but I am not sure if this is what i want. My problem is I live in Turkey and I have a Galaxy which is registered to me bought in thr UK. But I broke my thumb and cannot use it so I brought an Xperia Pro unlocked new from Sony UK. Under Turkish law a foreigner can only have one phone registered to him. How can I take the Galaxy IMEI number which is no good and the same IMEI number on the Xperia pro? I will never use the galaxy as I cant.
I hope you can help?
Best regards
Nick
The question I want to ask is.. After you upgraded your Mini Pro to ICS by the procedure you have written, what are your observations? Is it an improvement over GB via usage? Do some features of camera that were present in GB disappear when upgraded to ICS [i read abt this many times so am asking]?
Also, if I upgrade using MiniCMSandwich or after upgradation decide to rollback to GB and flash using the ftf link you have provided, are there any further things I need to take care of post the installation?
Please could you tell me the difference between restoring to stock and downgrading it? And, in case I too face problems after upgrading to ICS via official firmware or MiniCMSandiwich, which approach should I use?
I guess you are talking about the FXP releases. I have tried FXP 142, it is good but may not be suitable for day to day use as it is not yet stable. Many applications tend to force close every now and then. When CyanogenMod will come with a stable CM10 for Xperia 2011 devices, FXP will be very usable, I am sure of that. Meanwhile, I will wait for Kamarush for his JellyXProject rom.
The instructions are alright. You can flash any kernel that I have mentioned (krsh kernel, panic kernel, rage kernel, MESA kernel). Regarding the google apps, I cannot re-upload those kernel or rom files as those are not mine. You have to search google for finding the GApps.
sorry, I am using original GB 2.3.4 rom. even I am also cant see 2 router . symphony w10 device show all router & conect with all router successfully.
Q2: if I want to use coustom rom ( cm 7.1 & cm 7.2) between them which is best. can it solve my wifi issue. I want 2 see all router & connect with them succesfully
Q3:which kernal is best for this Rom?
please help me. bro?
I am afraid I cannot mirror Kamarush ROM or kernel (as requested by Kamarush). You have to search the internet for those ROM and kernel files. Regarding bootloop, I guess you tried a ROM with an in-compatible kernel. Please use the kernel that is suggested for the particular ROM.
thank you for sharing this powerful guide! tried it and it worked although I had to download an alternate rom as the link for your suggested rom was unavailable. here are several sites where I got the alternate roms from _07_01_archive.html and -developers.com/showthread.php?t=1748576.
That was really helpful tutorial. I searched a lot and i finally found your page to be useful and complete. I have a Xperia mini. I recently rooted the phone. I tried to install CM10 but i got an error. After going through your tutorial i came to know that i need to unlock bootloader and flash a kernel in the process.
Bootloader unlock is necessary as you will need to flash the CM ROM (or most other ROMs) through custom recovery (like CWM), and for flashing custom recovery, you need to unlock the bootloader. However, bootloader unlocking is completely reversible. You can always go back to stock recovery.
For using CM ROM, you need to use the CM kernel included in the zip file of the CM ROM. There are some kernels, which are written specifically for CM-based ROMs. You can also use those. Any CM-based ROM will/may not work with stock kernel.
Thanks buddy. I have successfully installed ICS custom ROM as mentioned in this post. Now i have relocked my bootloader and i have found custom ROM of JB for my Sony LWW wt 19i. Do I have to again visit the sony site for unlocking the bootloader?
after loading any custom ROM from CWM recovery its getting only Sony logo after that its getting restart please guide me is my mobile is compatible to change OS how can i find wether my phone is suitable or not???
Locking or unlocking bootloader has nothing to do with flashing the FTF file. Your bootloader might be locked or unlocked and you can still go to stock by flashing the FTF file. It will not change the status of the bootloader.
