[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
Certain installations make their own subfolder, some don't.

Seems like Android SDK didn't create the subfolder, which means it placed itself completely in Program Files and also saved it as the main directory.

Now, you went for the uninstallation. During the installation, you installed it there, so the uninstaller went to remove the main folder aswell, which in that case was Program Files. The app cannot understand itself, how important this folder actually is.

In that case, it is actually your own fault, not Google's or the application's. It is always safer to choose a custom folder by yourself, then it doesn't matter if installation makes own folder or not.

Also, during the installation, the location given default would show, if installation requires a custom folder in the file path or no. You could have seen, that at the end, there was \android-sdk written, which means custom folder is not automatically there inside created.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Feanor88:
Yep, just tried. The installer does remove the whole installation folder. I'd say two things:

1) I attached a screenshot. You could have easily understood that the installation folder was Program Files itself.

2) The uninstaller is a little stupidly done, though: generally, uninstallers are programmed to remove the program's specific files and directories and then erase the installation folder. True. But it's also true that normally if the installation folder contains files and directories not created by the installer a message will be shown saying Couldn't remove some files or directories, you'll have to do it manually.

So yeah, this is both yours and Google's fail indeed :D
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] hagen1993:
It was indeed not my smartest move, but I got so used to programs creating their own subfolder that I did not consider to make one myself. And the uninstaller should only uninstall the program's specific files indeed.

Ah well.. I found out that all my savegames are not stored in program files but in My Documents! :p It still sucks tough, have to install everyting again..

Thanks for the help!

Which way did you use to unlock the bootloader?

What happens if you try to relock it then?

I'll see about that.

Repair your firmware with Update Service(if you have stock firmware).

Else, reinstall the custom ROM or another one.

These lines are no longer in ICS config files.

If someone would give me info about that, I would appreciate this.

I do not have Mini Pro so I can't check it myself.

Installing Modules

I have a noob question here.

The kernel that I will be using says that I should install the "wifi modules" after flashing the kernel.

My question is, how will I install the wifi modules? What are the process and tools to use?

TIA :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
Download the modules, they are in a .zip file. Enter the Recovery(which is included in the kernel already) and use the install zip from sdcard option.

Hi,

I'm having trouble with this downgrading part:

I did everything the multiple threads have said to do to flash to a lower firmware, but I got an error in Flashtool saying that I don't have adb drivers.

I ran the drivers from the ones provided in the flashtool install location and still it was f-ed up. Same error.

Pc companion installed, adb and sdk on, im with.62 and I wish downgrading to .42 was as easy as just uninstalling updates.

Someone tell me what's wrong and is the problem that I'm running XP or smth?

Wtf with this dangerous crap just to use a simple root patch.

P.S. Is hard-reseting or factory reset etc. worth a try? I can't remember if I had stock .62 or something lower. Maybe that would fix the OS so I don't need to downgrade this long and stupid path here listed? I could then just try the zergroot..?

Please help me out here. This is misleading...

Custom Kernel

Thanks for the prompt reply Someguyfromhell. I have another question and hopefully you can also answer this or anyone from this thread..

I have flashed a custom rom (MiniCMSandwich Lite AOSP) to be specific but not its custom kernel because my bootloader is still locked. My question is, when I have unlocked my bootlader can I still flash the kernel even if I already flashed the custom rom first? Or do I need to flash my xmp to stock rom first before I flash the custom kernel then the custom rom?

Thanks.

New to Android - Need help on rooting my Xperia Mini

Just bought my Xperia Mini a couple of weeks ago and I'm new to Android OS. I'm a formerly Symbian user and I switched to Android. I'm afraid of ending up with a bricked phone. In Symbian once your phone is dead, you can still revive it using Phoenix (dead phone flashing), it's different with Android, you can't revive a phone once it's bricked.:crying:

I bought my Xperia and after a couple of days I encountered the "overheating issue", but the ICS update solved that issue.

Now I want root my phone and I have lot of questions to asked.

I want to root my device but I already updated my phone to ICS (4.0.4). I've read that I need to downgrade it to GB so I can root the device.

Let's say I already downgraded the device to GB and rooted the device, can I still upgrade the device to ICS but still rooted? If yes, how?

And also I don't want to unlock my bootloader, is it possible for me to root my device? Thanks

EDIT - Successfully rooted to ICS 4.0.4 (bootloader locked)

I'm wondering if anyone knows a proper way to restore the entire phone to stock ROM so I can send it to a repair center to get my phone fixed.

I know how to unroot using the same zergrush method but after that how should I reset the entire phone?

Should I just unroot and then run PCCOMPANION and restore it that way or use Flash tool and restore it that way?

Ok thanks. I'm just confused because I've read some threads that after they flashed their ROM, CWM recovery is still there.

I have another question. In FlashTool we have FlashMode & FastBoot mode option. I know FlashMode is for flashing ROMs

and Fastboot is for Flashing kernels, aside from that, what are the other capabilities of Flashmode and Fastboot mode?

Also both can flash kernels, but what is the difference on using those method?

I wan't to try Custom ROMs & Kernels since I already unlocked my bootlader, but I'm really confused reading lot of threads with

different methods.:crying:

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] pikpok:
Flashmode is for flashing *.ftf files, in most cases Sony roms and basebands. You don't need to have unlocked bootloader. It can flash stock kernel included in ftf package.

In Fastboot you can flash kernels in *.img format and you need to have unlocked bootloader to enter this mode. You can also flash rom, if you have system.img file, but most developers are giving zips to install in CWM.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Someguyfromhell:
If you have custom kernel installed, then Recovery is installed inside the kernel, so flashing the ROM doesn't affect it at all.

Fastboot mode is used to flash all kinds of system partitions, you can flash boot(kernel), system, data and some other partitions.

Why did you make a new topic aswell after posting it here? And don't quote the whole post, it's f**king huge.

When you are relocking bootloader does in Service menu says that bootloader is relocked or locked. I've heard that it says relocked in some Xperia models so warranty is useless then. What says in XM St15i (my phone) when you are relocking bootloader, locked or relocked if anybody tested it?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] melander:
I think it would say "locked" again, never tried it yet so I cannot confirm.

SEUS will not work with unlocked bootloader. To relock it you need to use Flashtool and this file, that I attached here.

To remove SIM lock, there is currently Ominus offering free service for the next 2-3 days. Better make it quick, else it will cost for you.

Relocking mini pro, check this thread.

If it says "bootloader unlocked allowed : no" then it is network locked.

If it is network locked then you would have to pay to unlock it.

It's been long that I have been following your tricks to get the most out of my android device. I got stuck up at one thing, maybe it's something silly that I have missed here.

2. rooted my phone

You have to install Android SDK first, then after the installation, run the Android SDK Manager and install Android SDK Platform-tools & Google USB Driver from the lists of packages. Then run windows command in the folder where you have installed Android-SDK. You must be in the folder where adb.exe exist. I installed mine in C: (ie: C:\Android\Android-SDK\platform-tools\)

Android SDK

You can install custom ROM w/o unlocking the bootloader. Well it depends on the custom ROM that you're going to install. If the custom ROM requires custom Kernel, then you should unlock your bootloader.
