[Q] Someone please help - Sony Xperia P, U, Sola, Go

Hi,
I have upgraded to ICS Swiss initially and the phone was working fine.
It was little bit laggy and I switched to HK and as there were many language problems I flashed Singapore ICS.
From then onwards my phone started behaving weirdly.
I used the pattern lock to unlock and lock and my touch wasn't responding and the pattern used to do weird things on its own.
I reflashed Singapore ICS and my touch isnt working.
I gave my phone to the Sony service center and I lost my warranty for rooting.
The touch is responding few times and most of the time it is not working.
I am stuck with this phone which doesnt work.
Please help, I lost my warranty and cant afford to get a new one at this stage.
I asked the technician at Sony and he informed it is the software problem and their system is not allowing it upgrade or change it.
Someone please help me, I am freaking out....
I would like to go back to GB, can someone provide the steps to do that. I do not have a backup of my previous version.

Why you didn't use flashtools?
You have unlocked bootloader???

I used flashtool to flash the ftf files.
I have unlocked bootloader.

Did you untick the boxes to save your data each time? If so, flash the swiss again, tick everything so you get a full wipe
Sent from my Xperia S on which The Kernel has been installed but he bought no chicken.....

Or re-lock your bootloader and use sus( sony update service) to repair the software and choose factory reset.

I checked all the boxes and followed all the steps everytime, but to my vain the touch doesnt work now.

I have done as you said, relocked the bootloader and downloaded SUS and did the factory reset.
The touch doesnt work. I think its a hardware problem.
The service center person informed that they have to change the mother board and its 70% of the cost of the phone.

I have the same problem. Flashed different firmwares with flasher and Setool, but touch still not working.
I have read that ther is an issue with flashing the stock Kernel on some Mini and Mini Pro
As i read that i decided that i Don't try to unlock the bootloader and Flash an insecure Kernel to obtain root because it is to dangerous
Lets hope that there will be an other method to root this device

From Setool support. You must have Setool box or dongle to be able to flash/unlock sonyericsson devices.
setool3-box.org
files.setool.net/support/SETool2
So you unlocked the bootloader flashed the Kernel and then got the Same Problem like me and your solution is to Flash the older Firmware and this worked for you?

Hello all,
I'm also fighting with this problem. Has anybody more information for the reason of this bug?
My Phone:
Xperia Mini Pro SK17i 1249-0812 TYPE: AAD-3880104-BV
Bootloader is unlocked.
The Status:
My Phone is booting and all physical keys works but the sensor buttons and the Touch display is completely unresponsive/unusable.
I' ve tried different update tools (flashtool, wotan, install from CWM) and different roms:
FXP052-update-cm-7.2.0-RC0-XperiaMiniPro-SK17i-KANG-signed.7z
SK17i_4.0.2.A.0.58_(1249-7380).ftf
SK17i_4.0.2.A.0.58_GLOBAL.ftf
SK17i_4.0.A.2.335_FRENCH.ftf
also tried to update the kernel from [KERNEL] KRsH Kernel v2.0 (MiniPro)
It always results in a nearly working phone with no response from the touchscreen.
Would be very appreciative for any help!
Thanks,
Bernhard
Bought my wife a mini pro which was a SK17i
It came today and worked for about 20 minutes while I put all her stuff on it.
Then all of a sudden the touch screen and capacitive buttons stopped responding.
I had a similar issue on my x10 mini pro which related to the homebrew dual touch driver. Stock restore from SEUS fixed that.
Tried that on the xperia mini pro but it didnt help.
I've sent the phone back as faulty now.
Would be interested in hearing if the problems here are software or hardware.
Cheers
Hi guys, I have the same problem like everybody else - the touch screen doesn't work niether the capacitive buttons.
It happened when I thought I caught a virus after downloading an aplication : THE SEARCH ICON
Probably this was really stupid thought, but then I decided to make a full factory reset. My phone was rooted and after the reset the super user icon was still in the aplications. Then after 2 minutes using the phone it crushed, so I decided to unroot and then to make another factory reset and I did it.
Then the home button didn't work and the phone crushed few more times.
So I used PC Companion and update to .62. The phone was Ok for a week then it's screen and the capacitive buttons were useless.
I did 6-7 repairs from Pc Companion but still nothing.
Then I use Flashtool to flash it to SK17i_4.0.2.A.0.58_GLOBAL.ftf and again nothing. Then I flash it to SK17i_4.0.2.A.0.42_Generic_Trade_United_Kingdom_(1248-7407).ftf but still nothing. After that I updated again to .62 and no result.
IS THERE SOMEONE WHO CAN HELP PLEASE
Try Sony Ericsson Update Service to restore firmware completely.
I tried Sony Ericsson Update Service, too! Even with full factory reset and update to the latest firmware .62 and still the same problem! What should I do?
Someguyfromhell thanks you for your answer. I don't know why there are no posts for fixing this. Everybody asked for solution, but still none answer! I can't use my phone for a week now. It is really annoing . Please I really need help!
Sounds like the same problem I have. I was using hybrom + krsh kernel for months and was really satisfied with the phone. Then about a month ago the touchscreen went suddenly unresponsive for a 10 seconds or so. After that these lock ups started to became more frequent. I installed logcat and noticed it had something to do with touchscreen driver in kernel.
Next I tried bbooff's kernel but no avail. Then I used wotanserver to install stock kernel and rom, relocked bootloader, updated with pc companion, uninstalled all software I installed from market, did a 100% complete factory reset...
Then after using the phone for 5 minutes without lock ups I was really feeling victorious. I guess I forgot to knock wood because the touchscreen froze again. Now the phone is at the service center.
Either there is some really weird bug in these custom roms we all used or the hardware is bad. I never overcloked my phone more than 1,0 GHz -> 1,1 GHz so that can't be the reason.
I hope the service doesn't cost too much. I think I voided my warranty when I unlocked the bootloader and installed a custom kernel. The saddest thing is if it is a hardware problem caused by a bad hardware or a design fault I would still have to pay for it.
I understand, but it is really wierd, because I didn't use custom ROMs at all. I just made factory reset on a rooted phone (without unlocking the bootloader) after that I update to .62 from PC Companion and then I used the phone for a month and like yours the touchcsreen was dead for a little bit and the capacitive buttons, too. After that these lock ups started to became more frequent like yours. Do you thing that I will void my warranty, too and is there a solution for me?
Anyone with solution?

[SOLVED]Xperia Neo dead after Flashing

Hi,
I bought my neo just a month ago and I got an indication for a new update available for my phone yesterday. I did a FOTA and my phone just stopped booting.When I press the power button all I get is a blinking green light, nothing on screen.
I had unlocked my neo a while ago.
I tried flashing it to MT15i_4.0.2.A.0.42_Global version. Still nothing.
I have tried SEUS and PC companion. My phone gets detected but they say i have a modified software and thats it.
Please help me, it hurts having lost a month old phone......
Thanks in advance
Well i got my phone up and running.....
For those who are still struggling check out the following link.....
http://forum.xda-developers.com/showthread.php?t=1324707
First of all , if your bootloader is unlocked-RELOCK IT.
After that , try flashing the stock firmware or use SEUS.
That's how i got my NEO V up and running.
No harm in trying the same method with NEO.

Yes, try this! It should work! If there are news just tell us!
When people go to bootloader unlock their phones, do they completely miss the prominent warning or what?
Some customers with unlocked boot loaders have experienced problems when they are accepting over the air upgrades (FOTA - Firmware upgrade Over The Air). For customers that have unlocked the boot loader, please do not accept any over the air upgrades. For additional information, check out the hints and tips from the community on the XDA forum.

Unresponsive screen, dead PC connection, more.

Hello people, I really hope you can help me out on this one. I own the Sony Xperia U, which I had succesfully bootloader unlocked and rooted months ago. It had been runing ICS smoothly and everything was working great, until two days ago, when the screen started ocasionally missing/ignoring taps/sweeps. It was a real pain to type since it would miss a letter or more in every word I typed. I decided to do a factory reset, and so did I. The problem was not fixed. Now, I'm dealing with more: My computer does absolutely nothing when I connect the XU, and the phone itself only recognizes a charger. The same in debugging mode. Superuser does not work (can't get root access despite it says it has granted the rights), I can't even uninstall Superuser. What are my options? Can I somehow flash some things and do a full reset of the phone? I have CWM Recovery installed!
Thanks in advance!
PS: The main ambition is to get rid of everything but the screen problem. I'll probably replace the digitizer after that.
Anyone? Sorry for second post!
Proberly hardware problem. But you unlocked your bootloader and your pc is now as good as nothing. Just pay for the repair :-\

Well, I would recommend to flash stock again to remove root and relocking the bootloader and if the problem gets solved, root it again.

[Q] Xperia Ray Boot STUCK!

Hello everyone i had a serious problem with my friend Ray (ST18i) . My friend said that his phone is freezing and restarting when playing some games, and then BOOT STUCK (not boot looping) at the SONY logo when gonna enter the system (when the screen light up) forever.
I already tried to flash stock firmware many times with build 4.1.B.1.13, 4.1.B.0.587, and 4.0.2.A.0.42 but the result is the same, i even thought that this phone is updated via OTA with unlocked bootloader so i do flash Xperia 2011 Range_FreeXperia_ALL.FTF by FXP and Xperia_Relock_bootloader.FTF . And the result is still the same. I even tried to repair via Sony PC Companion and Reflashed it via Sony Update Centre, but the result is the same.
The thing is my friend is just some average Android user that don't know and don't need to root or even unlocking his phone bootloader, so he's never did that thing. so i can't go to recovery (cause there isn't any) but luckily the phone still can go to flashmode and fastboot, and even showing battery chare image when charged in Turned Off condition.
I really need help from you guys to fix this issue, cause the other problem is, there isn't any Sony Service Centre in my city, and this phone isn't even bought with official warranty. I had some exprience with samsung, and many Xperia (Now using hTC though) but this is the first time i'm facing this kind of problem.
Thank you.
Have you tried unlocking the bootloader and flashing the stock kernel with cwm? Then i would wipe everything incl system and format the sd card (make back up to pc) so you have a complete empty phone. Afterwards try installing stock firmware.

Thank you for your kind reply
Yeah i would like to try that too, but, correct me if i'm wrong isn't to unlock bootloader you need the IMEI code from the phone? and as i know it, to get the IMEI code you need to enter *#*#7378423#*#* or such in your phone dial and see the IMEI code there. After reading your suggestion, i come up with an idea to unlock it via someone else Ray Unlock code from SONY, is it a good idea?
When i reflashed it with flashtool, there isn't any sdcard and simcard in the phone btw.
Or maybe there's some way to do a full wipe without entering a recovery?

Yes it was successfull like always with the final word, Flash complete and please unplug your phone. and device connected in flashmode.
I'm about to try unlocking the bootloader first (If i can't locate the IMEI, then the test point way will do) and then, flash a stock kernel with CWM and do a full wipe first.
I think it's still early to give up, because i think there's still so many way to fix this thing rather than just flashing a stock firmware.
I hope many awesome developer like Doomlord or bin4ry will at least take a look at this thread

no there is nothing much fr us to do.
and if u would like them to fix it please contact them personally
I personaly suggest you to unlock your bootloader using the test point method rather than the sony method. That way you still have your original drm-keys.

UPDATE on UBL
Hi Everyone, yesterday i tried to unlock with 2 ways, the first way is with the SONY Official method even though the phone doesn't boot, i can get the IMEI from the back of the phone, and from the BOX (which is basically the same IMEI) and got the code from SONY. but unfortunately every time i'm in the final step i got : Remote oem unlock failed. And i'm sure i'm updated and using the latest Android SDK. i even tried to do fastboot command from other laptop but the problem still there. (Tried to google it for the same questions like that but what i got is only people that had a mistake in inputting the code number) Note: I already cross checked it for many times, that now in my inbox i had 5 same codes from SONY :silly:
Next is the Test Point with s1 tools method. But like always in the final step, i got another error which is: test point qcreceivepacket can't get packet start i tried to google it again (which is always leading me to XDA cause here is always the source lol) many people answered that same questions which is because the Xperia you're trying to root got a new version 2012 and something like that.
Note: I'm pretty sure the Xperia Ray i'm unlocking is Bootloader Unlock Allowed: Yes, because when it's still alive i already checked it via *#*#7378423#*#* and 1 more thing is because i already tried to unlock an Xperia Mini Pro that is Bootloader Unlock Allowed: NO. Which is really can't be unlocked because the phone with that kind of status can't go to fastboot (always go to charging mode instead)
Maybe you can say i had a lot of experience with Android, but i'm just creating the forum account yesterday, so i'm still a NOOB here
which is why i appreciate all the help from you guys.
I'm gonna try Contacting the top Xperia developer (which is i still don't know how) ASAP
EDIT: Just read someone questions on Q/A General chat thread. That the reason i'm failed is because i haven't rooted my phone? Is it true to unlock you need to have a root access first? cause in my other Xperia (Active, Sola) i always root first before unlocking so i don't know if unlocking first will do.

But after restarting only sony xperia logo comes and goes.
I repaired phone using sony pc companion. But no use.
After updating again sony xperia logo comes and goes continuously.
Please help me as service center is very far from my town.

No friend...its not rooted
Your phone seems to be stuck in a bootloop.
Press the Power button+Volume up button and hold, till you get a screen which is the recovery screen!
Now, you should be able to see options like Wipe Cache, and Factory reset.
In order to get out of this bootloop situation, first tap on Clear Cache.
Then tap on Factory reset.
THIS METHOD WILL DELETE ALL USER DATA.
But you can't really backup anything since you don't have access to the phone.
Try this out, and keep me posted.

Download flashtool, flash http://forum.xda-developers.com/showthread.php?t=2489955
Set it up correctly and instal;l the drivers.
Download the ftf file for YOUR DEVICE, use this http://forum.xda-developers.com/cro...xperifirm-xperia-firmware-downloader-t2834142 ,or the last tab at the top of the flashtool.
Once you have found it, click it and download it by clicking it on the far right, make sure unpack automatically is checked.
Let it download and then flash tool will assemble it as the ftf file for you, and it will be in the correct folder. Cick the lightning button and select flash mode, select the ftf file that should apear in the list.
Folow the on screen instructions, it will take a while to flash, once finished it will say "unlug and reboot phone£
Do that and your done.
Cant fail with the flash tool
Let me know how you get on. Goodluck.
is your display ok (no small hairline cracks UNDER glass)?
I did all from your instructions and even try repair option in PC Companion but, had no errors but my e2303 remains stuck on the Sony logo (looping). I bought the phone online second hand and it arrived like that. I did bootloader unlock procedure in flashtool successfully and when i run it again it offers relock now so i assume it was good. However, if i try sony official bootloader unlock instructions via adb, i get error. I guess it's debug over usb and unknown sources related but since i can't boot to system there is no way to check that.
I'll mention i did try several ftf versions and all flashing went without errors (as with pc companion repair) but no result. Did i got scammed totally (i know i am as the phone should be working) and bought a phone that even can't get repaired?
Help guys
Do you have deleted or disabled my Xperia app before unlock? Maybe beacause this. I read when unlock and active my Xperia, phone is like paperweight
I got the phone like this, stuck on Sony/Xperia logo so i don't know what happened and what is the cause
Hi,
Apparently this is a more frequent issue than I'd have thought.... A relative of mine brought me his M4 Aqua e2303 with the same symptoms: it tries to boot, shows the Sony Logo (Xperia on the bottom of the screen) and it just loops. Screen goes off-then-on and the same thing. I've tried EVERYTHING. Bootloader was locked, so as a desperate measure I even unlocked it via Flashtool. First I tried Sony PC Companion App and automatic repair. It went smoothly but the phone was still stuck, then I flashed the last ROM via Flashtool. Again, everything went OK, but the phone was still stuck. I flashed a different ROM, the European Press version, since it's a little bit older, and suddenly something changed. The boot sequenced advanced from the Sony Screen to the waves screen, even with the music, but it just freezes and reboots itself 3 or 4 seconds after the blue-ish waves screen appears and the melody starts playing. Fastboot works, and I even pushed a custom recovery image. It boots, works, touchscreen and everything, and I can wipe everything (which I even did) but to no positive result. I've read about theft protection bricking some M4 Aqua phones, but this one had a locked bootloader, so it's out of the question (I think)
I'm absolutely dumbfounded... the only thing that comes to mind at this point is a hardware failure. My relative got the screen replaced, but everything was working fine after that, so I guess some cable/ribbon/whatever could get loose over time? Any idea?
I've learned a lot reading this thread and XDA Dev generally. Thanks, guys, great community.
hi,
i got to this problem too - M4 E2303:
1) unlocked bootloader
2) played around with the infinite possibilities of an unlocked bootloader.
3) killed android one way or another (debloating by hand, etc) - but it all worked again, thanks to the custom recovery
4) repeated step 3 a few times, until i liked the result
5) when creating the backup in recovery mode, the phone overheated constantly - so i submerged it
and this is how it went sour... i am still not sure, if the killing blow was dealt by heat, water or some other action - the phone just shuts down when i start it, while custom recovery works. flashing works also - over fastboot and the normal fashmode.
the interresting part is, that after flashing the bl back to locked even the sony recovery tool accepted it and flashed it again - but it won't boot anything else, just recovery (after unlocking and flashing it again, of course)
the only possibly useful info i got for you, is this log message in the twrp-console, which i did notice since then:
unable to recreate and-sec folder
maybe this helps others to identify the problem/solution for these strange bootloops
p.s.: even though it is only one possibility for what killed my phone: DO NOT use "the waterproof phone"(tm) under water
p.p.s: Cyanogenmod 12.1 works (well, as "well" as on any other m4) - i just installed that from an sdcard via twrp
I have a xperia m4 aqua, it have the same problems, but I´m thinking if a break glass or a crack has something to see with this problem, can you e-mail me? [email protected] please.
Hey, mine is also stuck in a bootloop.
had the wifi of for 3 days straight. Next time switching wifi on the phone just shuts down and gets stuck in a bootloop for like 45-60 minutes. Wifi is off, as soon as I activate wifi again. Same all over.
Any suggestions?
Did a restore from the original software also with other versions.
I guess its a hardware problem. But no glue how and why
got same problem here, could it be because glass is cracked?

Ahm i have the same problem too. Please tell me how to use flash tools on mac os
Hello everyone,
I have the same problem. It started when i saw that i had no 4G internet connection, so i thought lets restart my phone and yes now its in the bootloop .
I tried all kinds of resets, i tried to flash my phone which i did with succes, but still have the bootloop.
Now i have some questions:
- when did your bootloop started?
- Did u play pokemon Go?
- Was your phone warm or cold?
- Could it be a storage thats full?
- Do i have to bring my phone back or do i have to buy a new one?
- Could it be an software update that caused this?
The pokemon go thing is because it is a possibility that the game overheated your phone and maybe some hardware got damaged because of that.
i'm not sure of this, but there is a great change that thats the problem.
Hope we find the answer.
