Unresponsive screen, dead PC connection, more. - Sony Xperia P, U, Sola, Go

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] bricked x10?

ok, devs and friends, i may be risking a ban here, i just can't find a similar case like mine through 'search'. Ignore me, ban me, whatever suits you.
Here goes; i have an x10, r00ted and the like, locked bl, tried a few fw's - all well.
then i tried a miui prime and flashed a lockedbl patch, as i thought i should.
since then i'm unable to boot, stuck at 'sony ericsson'.
no way i can access the cwm5 or xrecovery menu, the flashtool works at the beginning but then orders me to turn on debugging, which is impossible since i can't boot at all.
i hope someone will take the time to help me.
thanks a lot!
Locked bootloader patch..I am not sure but is that for phones with an unlocked bootloader to use a locked bootloader rom..or the other way around...
anyway..back to your problem.
Download pccompanion run it, attach phone to pc and click start in support zone.
It may say you have the latest software but their is an option to install anyway (Repair) phone..do that...
big thanks for the immediate response!
i've been trying to connect the thing but the battery won't even charge and when i managed to get through for 2-3 seconds, i had no luck with pccomp.
(btw, the locked bl patching was meant to be done - or so i thought, at least.)
i'll keep on trying tonight.
thanks again.

[Q] Bricked S5830, please help me

Hi all,
I have looked for a similar post, I found out that many people experienced something like that trying unlocking their phones, but I haven't found out any solution.
Here is my situation:
I have tried to unlock my s5830 (orange spain carrier), I have used a method which it seems to be dangerous for the phone, but of course I have found out it was dangerous after I have already tried it
Anyway after I discovered the unlock number contained in the perso.txt file in the efs folder, my phone restarted without service once and after that it went in a bootloop mode, it goes on a download mode, but there is no way to get back recovery mode or a normal boot.
I flashed the s5830 several times with many firmware, but no one worked, and the phone is still stuck in an infinite loop, in which I am not even able to see the samsung logo coming out at the very beginning.
I know many phones got bricked in this way, I wanted to know if anybody has been able to recover the phone or if anybody know any possible solution.
And if not, do you know if the warranty is covering this problem? I just got the phone a couple months ago; i have unlocked other devices before, but this is the first time I have experienced a problem so I am quite new about warranty as well. Please HELP ME
Merry Christmas guys!!!
Thanks in advance

with the cellphone off, put out ur baterry for a minute, then maintain ur finger into the volume down button and the power button tell a friend or if u can alone insert the batery while quickly pressing volume down and power button to get into download mode, and flash.
Hehehe,bootloop is horrible,you just have to get in download mode & flash with 2.3.4 firmware with Odin,just that steps and you save your SGA.
I got bootloop many times and Odin saved me.

If you can go to recovery mode than you can just wipe the data and cache. This saved me many times. Otherwise on what ever OS you may be , just create new user name after removing samsung android drivers. Login from new user name and than re install drivers again and now flash your phone from firmware which was installed on your phone before you bricked it. This helped me a few times.

It seems that you've already received a lot of help for unbricking your device. So I'll try to help out in unlocking your phone after you finished unbricking it.
This is the method I personally used on my locked Ace:

thank you very much I will follow your advice...IF I will be able to get my phone back which seems impossible =(
@dr_vishal
Thank you first of all, I have tried to uninstall and reinstall the android device driver, but it doesn't seems to be the problem, Odin ends with a "PASS" at the end, I guess there still is comunication in the between the two devices...
Hopefully it will be a Merry Christmas =)
It's not impossible. I'm relatively new here but I have noticed quite a few "bricked" threads already. Most of them (if not all) have been able to fix their device. I haven't seen a single person permanently brick their device, so I would guess that your chances of fixing it are really high. Just be patient and keep describing your situation and more experienced help will certainly arrive. I'd really like to help out but I have no idea how to fix it as I have not experienced bricking my phone yet.
Anyway, if the method for unlocking I suggested works for you kindly press the Thanks Button. Merry Christmas!

Guys,
I am out of ideas, I have tried each single firmware I have seen around internet, no one is working, any tip or advice or suggestion?
I messed up with the efs, and I guess that's all, the phone is gone....now it needs a JTAG or whatever is its name....
maybe to get the warranty still valid I should broke totally the phone over charging it....??

just a thought
a lot of people have talked about reflashing it and all but have you managed to get into the recovery mode at all once you have reinstalled the rom with odin? if you can get to that you just need to hit factory reset, wipe cache and wipe dalvik and normaly after that it will work fine... so far ive been stuck in soft brink 3 times and each time doing the wipes from the recovery mode has worked...

I've tried to use the oneclick, but it seems it doesn't recognize the phone, since, i guess, it's made for a galaxy s.
The others are not my case, since I am able to get download mode, and all these are made to can get it back.
Anyway I found out a post in which the people were talking about the s5500, which apparentely is similiar to my device, and the owners of that model experienced a similar problem doing the same process....anyway in that post the people needed to use a Jtag, which is the only way to get it back....so I though it could be the same solution for my problem...but I don't know anybody with Jtag, so the only way is contacting the service center.
thanks anyway, when I will be back at home after Christmas I will try to find the ticket and I will probably try to get it back in warranty, since is preatty new...
@torchwolfery
I am not able to reach recovery mode, there is no way to get it back, even flashing the phone with different firmwares, all I got is download mode, and apparently that is completely pointless...since the only change in the phone behavior is that if i install a certain firmwares it doesn't even have the back-light working when it is stuck in bootloop.
Warranty is your only hope (as it was mine once and it worked).
I didn't think it was possible to brick these phones. There I have tried so much to try and brick it but I have not been able to as it still always goes into 'download' mode. The only advice I can give you is double check that you are using the correct version of Odin which is v4.38 and that you use cooper v1.0 as your OPS. If dont mind me asking, but exactly what did you do or do you remember the steps you took to brick it? What buttons are you using for 'recovery' mode.
Also please clarify if Odin is going in a loop or does the phone come on and then keeps rebooting? If it is the phone that keeps rebooting, then wiping cache and data partition should do the trick. This can be done by going into recovery mode (which I am aware you cannot get into) or if you can manage to get into the dialler quick enough before the reboot, by dialling *7267*3855# and that should format the relevant partitions (data and cahce) and bring it back to factory settings. Without further info, I cannot really tell exactly what the situation is.
The fact that you are getting 'download' mode, I dont think that it is bricked because it will still allow you to write the relevant directory/files to the relevant blocks. Either way, would be interested to know.

[Q] WIFI keeps searching and didn't find anything.

Hi mates!
Few months back I unlocked my bootloader and recently used many custom ROMs and kernels. Unfortunately I could not use my wifi properly - I was on FreeXperia kernel and at very start wifi worked ok, but it stopped finding any networks after couple days of rom usage. Problem was reported on the Android Development sections in the ROM thread by many users, so I thought it will be fixed soon. Couple days ago I switched to DoomKernelv3, his wifi modules and Oodies MIUI ROM - worked perfectly but my wifi worked occasionally and stopped working again. I got back to stock now and I'm on Z's Recovery (very first one I used and had no wifi problems) and problem with no wifi networks still persists. Did I brick my wifi somehow? Is it possible? Does anybody experienced similar problem?
Any help would be GREATLY appreciated.
hey
honestly... i think there is a hardware problem in your phone....
cuz even after switching rom's you still have the same problem....
i would sugggest that your use seus and get back to stock version... and just get it fixed by them.....just keep saying them that wifi doesnt works and all.....

it does lock.... coz every-time i got f'd while flashing i used seus and had to unlock the boot-loader every-time.... even though i checked with s1 tool first if the boot-loader was locked or not....
any way if you r on stock rom... those repair guys... wont even notice that you flashed the device
Hi!
I have had the same problem as you. Still after repairing it in PC Companion, the problem was still there.
So I left the phone for couple of days because I got Xperia S, and when I turned it on one day and searched for WiFi networks, it finally found some networks!!!
I don't know what 'fixed' it, but I think it's a hardware issue and I was going to get it repaired until it fixed itself

[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.

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.

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.
Don't worry, All is Well!

I repaired phone using sony pc companion. But no use.
After updating again sony xperia logo comes and goes continuously.

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.
