then probably you had got a sim lock . i guess . i never had that before .

Hey again peeps :)

Am getting quite addicted to the whole rom flashing thing now and after looking through the MiUi roms on offer, i saw someone comment about "for those too lazy to port their own..." or similar so thought i'd have a go :)

Saw someone's thread with MiUi4Xperia in it and have used their software. I downloaded MiUiAndroid LT18i 2.8.10 and took a CWM backup from my phone with Nordic 4.0.4.

The instructions ask for the system.img but CWM was system.jaff2.img or something. M4X didn't recognise the original CWM img so i cleared out the folder and then renamed CWM img to system.img. M4X seemed happy enough and rattled through with signed zip at the end.

I flashed it through CWM over the stock 4.0.4 kernel and it booted first time (i w00ted :D). One slight problem however, touch is a bit wonky. When i touch the screen i get a blue hoop about a centimeter below my finger. I found i could drag it around the screen fine and shift the screen with 2 finger dragging but it's not really usable.

Just wondering if anyone else has come across this? Tried googling but couldn't find much. It's not exactly a matter of life and death or anything, have gone back to rooted 4.0.4 for the time being. Just my first foray into any kind of techie stuff like this since senior school and wondered if anyone has any experience with this without needing to research.

cheers in advance for any help and thanks to all the devs for the roms i've been playing with :)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] -Jesco-:
go to settings --> developers options ---> Show touches or something similar <---- make sure that option is disabled .
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Eldwafio:
cheers for the quick response matey.

when i had it on yesterday I did have a look through the dev options and it was off. Worried i'd borked something i turned it on and got what looked like coords at the top of the screen and a multicolour square around blue hoop. Turned it off and got rid of those, blue hoop remains below my finger when i touch.

I also checked for pointers and that was off as well. Think the only option in the dev menu switched on was usb debugging as i'd been pratting about earlier. Maybe i've done something wrong renaming the cwm img :S

ta for the suggestion though.

What build number is your ray? The last stock builds for GB and ICS cannot be rooted. You have to use flashtools to downgrade to rootable builds.

Strange Issue

Hello Developers.

After I have tested several ROMs, I would like to return to the stock-ROM. But now I get the following messages in the logfile constantly.

E/CMarlinMediator( 135): Error : MarlinMediator Failed to get TrustedTime
E/SemcSettingsParser( 1320): key not found. key=[brand]
E/SemcSettingsParser( 1320): key not found. key=[group-visible]

What can I do to make these messages in my logfile does not remain so unnecessary flooding. I fear that one of my attempts have corrupted my DRM keys or destroyed .. I unlocked the bootloader with the test point method.

The detailed log file I've appended with.

I hope someone can help me with the problem.

Have you installed the drivers for the Ray in flashtools?

EDIT: It's all a bit of a PITA but you'll get there in the end. It took me about 3 days to get root and then to unlock my bootloader (official way), combination of messing up my IMEI submission and getting an incorrect unlock code/not understanding fastboot/typing in commands wrong.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Parkside:
If you are able to use flashtools to flash a ftf, I'm pretty sure everything you need is in place.

Do you have Sony's PC companion installed on your PC too? This also installs drivers, when you connect your phone to your PC by USB.

So lets start again, do a full flash of 4.0.4

Check your phone boots up ok, go to about phone in the settings menu and make sure the android version is 4.0.4 and the kernel version is 4.1.B.0.431

Make sure you re-enable USB debugging.

Power down the phone again.

Use flashtools to flash just the stock kernel for 4.0.3 (the small file, under 5mb)

Re boot your phone - check your kernel version, you should now be on 4.1.A.0.562. This kernel is rootable.

Make sure USB debugging is enabled.

With your phone on and USB connected in MSC, open the rootv5hack on your PC - follow it's instructions.

Once it has worked, your phone should be rooted.

You should have the super user app in your app drawer, update this on the market, download busybox, download the CWM xperia app. Install the lot.

Power down the phone and flash the just the 4.1.B.0.431 kernel. You should still have root.

These things are sometimes inexplicable - yesterday I flashed a new rom, followed all procedures correctly (I think) and my phone wouldn't boot. Re-flashed and it worked fine. Often it's just one part that you missed out, our did wrong which causes the problem.

I bought recently an Xperia ray, bootloader blocked, updated to 4............62 Then, I realised that this firmware cannot be roouted. So I`ve downloaded previous firmwares, 042 and 058 and tried to flash via flashtool so as to revert my 062 firmware to those 042 or 058. ut there is no way to flash. I start flashing win the phone switched off and ge this message:

Another touchscreen stopped working problem :/

I did post something a while ago, and as I ve been told i sent my phone back and they changed my screen (my battery was apparently dead too) After 20 days i got it back fixed.

I had to re unlock and put a MIUI rom which stops working during one night so i tried to use blendmiui software which recommends to dl a desire hd rom etc ... I did it then my screen stopped working again.

I don't know if I m cursed or just plain stupid, but I can t get it back to work again.

When I flash back to stock the kernel just hangs at Sony Ericsson logo, and if I flash a custom kernel I boot to the welcome screen but then my screen isn't responsive at all and animations are showing so it s not frozen :/ I also tried to relock the bootloader and use the seupdate which didn t work (stuck on logo again)

I reunlocked it and i can install cm9 or miui no problem from a recovery flash but no screen action whatsoever...

could it be a baseband thing ?

I don t know what to do I would really appreciate any suggestions

Thanks

Could you be more detailed? What custom kernel, what method of unlocking? Are you sure it's st18i not st18a? What was the experience when you got it back before you flash the MIUI?

@bazonga: well I don't know, cause he said he never unlocked the bl so why relock?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bourrinlepoulpe:
I used the fastboot unlocking method. When I got it back everything seemed normal as far as i can tell, but I had it for less than a week and didn't get to use it much. the first the screen died within a week too.

So far doomlord's kernel seems to be the only that can access the stock rom, I tried the one from 4pda without success, although i can access clockwork recovery from it.

Yes i did make sure to use only st18i, i tried to flash *.42 and the *.62 (each with their respective baseband, .58 and 64 if I remember correctly) stock wise and no luck at all and flashtool doesn't give me any errors.

go to where your fastboot.exe .. And copy the kernel in the same directory where your fastboot.exe is .. then press SHIFT key right click your mouse and chosee open command window here

then it will open your cmd make sure that you are in fastboot mode (the LED is in Blue) and type: ( fastboot devices ) to make sure your device is connected and the fastboot recognized it

the just type:

( fastboot flash boot your_kernel_name.img ) >> if your kernel is named Ray.img For example you'll type the command like this: (fastboot flash boot Ray.img)
