Can not go back to stock from Concept - Sony Xperia X Questions & Answers

I have decided to roll back to stock firmware on my Xperia X, but every time I try to do a software repair in Xperia Companion it says "Initializing" and after a few minutes "Network problem:a network error occured while downloading the software. Make sure you are connected to the Internet and try again. Your device remains unchanged." Under that it says "UEDownloadServiceFailed UE_2001 1.9.2.0./Windows 10 64bit/ Win 32/US/F5121/38.4.A.0.45" I tried multiple cables and multiple ports on my laptop, but with no success. My question is did anyone have the same problem as me? If so, have you found a solution, and if not, is there any other way to go back to stock? Thanks!

You can go back to stock by flashing ROM through flashtool.

[Q] x10i won't start

first of all let me say that i've don a lot of searching before posting this, and i know it seems pretty long but please try to help me.
i got an x10i from a friend few days a go. the reason i got it (for free) was because it's not working and he didnt want to mess with it anymore.
when i first got it, if i tried to turn it on, the led would flash red. once in a while it got turned on, the sony ericsson text appeared for a few seconds and went off again. now if i try to turn it on the led would flash green for a sec, there is a vibrate but thats it. screen wont turn on at all.
i'f i try to connect it in the SE PC suite it detects it, but fails installing it. i've managed to enter the repair tool, but it failed a few times. however, the last time i tried to repair it said that it was repaired succesfully. still, not turning on.
tried to flash a firmware via flashtool, seems like its going well all the way but in the end it says "error flashing. aborted".
i'm pretty much out of ideas now, so ill really be grateful if anyone could help me.
a little update:
i've manged to flash a firmware via flashtool and it finished without any error, but still it won't turn. only the quick green flash and vibration.
any help will be appreciated.
ok, big update:
the phone is starting, i get past the boot animation and see the main screen (!) but after a sec or 2 the screen freezes and the phone shut down and won't start again unless i replace the battery?
please? anyone? im feeling so close yet so far away. could be a battery issue? when the screen starts i see that the battery is almost empty (connecting it to the charger won't help)
Yesterday i had the same problem ... i had to flash the hole firmware with X10Flash-2.1 and then updating with seus.. after this it restarts and it boot correctly
Not sure if u tried this, try having the phone plugged into the charger and let it charge for a while and then try booting it up again. Firmware wise, I would try a stable 2.1 or the freex10 beta 2.2 for a start to ensure that the software installed are stable ones. Hope this help.
try to fix it with seus...
nothing else willing to work as it seems there is something wrong a little deeper than flashable files...
This is I believe 1000th thread about this.
1. run seus
2. run PCC
3. run flashtool
Done.
SEUS seems to be the most effective way of repairing this.. Although you might also want to try pulling the battery before it freezes, it can help to recalibrate the battery.

thanks to everyone who replied.
i've downloaded and installed on the phone the version by SEUS, but i still cant turn on the phone.
in PC companion nothing is happening. when i go to the support section to get the new version, it just connecting with the phone and then tells to disconnect the phone and turn it on (which of course don't happen).
i've tried to run a repair in PC suite but it fails.
i've also tried to flash a firmware in flashtool, but it also fails.
any ideas?

with the first and the third ones i get an error, but with the second i don't. however the device still won't turn on.
is there any chance that because i'm using win 7 64 bit it causes problems?

If i am not wrong windows 32/64 bit does not affect how ur phone is gonna be installed since the installer that is downloaded is for the phone only and the installation process will only be done by the phone itself.
Not sure if u tried a different software such as xrecovery to install the OS into ur x10, since xrecovery with freex10beta4 works for almost all of the users in here, it should work for u if ur x10 has no hardware faults. If all still fails, it might be most probably your x10 hardware has failed or something along those lines.
It work for me, then with the 1.6 you can after that update with seus to 2.1update 1. If your phone doesn't work anymore you have nothing to lose.

the original 1.6 is on this forum also... please make some commercials somewhere else... k thanks...
4 out of the 9 posts u made had something to do with this website... could you stop please?
@the win7 part... you could get problems if you dont got the right drivers but it would tell you or error out...
the only thing what you could do in my opinion that is is short the pins while battery has been removed
this should effect total emptied phone and hopefully also the memory.... maybe than you are capable to flash/start it...
now if this wont work.. im sorry but im out of ideas and u shud use it to make a new barn or house ;/ im sorry
Didn't know the 1.6 was on the forum, thanks for the cue. I won't talk about that anymore.

x10i wont start up

Hey guys,
I have an x10i that just went dead one day, I thought it needed a software re-install so I did it. Now it wont turn on and I just get a quick green blink and a vibrate when I turn it on. Ive flashed it 10 times via sony update too and pc companion and flash tools. I dont know what to do, any help would me much appreciated.
Download SEUS from Sony and flash. Make sure it is fully charged and make sure you are using the right USB cable and try using several different USB ports on your computer if the first one doesn't work.

Thanks for the response, I have a fully charged battery and just re-flashed with still no luck. What did you mean about the "right usb cord" ?
Thanks again.
I mean reflashed with SEUS (not PC Companion) and by right USB cord, I mean the one that came with the phone. Or if you have the possibility, try another one.
Tried with 2 different usb cords and on 2 different cpus. I think Im S.O.L
One more question, after a flash how long does it take for the xperia to boot up?
During a flash with SEUS it tells you when the phone is rebooting....same with the Flashtool.
Screen turns on...still black...then Sony logo, then your bootlogo followed by desktop.
http://www.youtube.com/watch?v=HmX-IYNYqL8
Is it successfully flashing using SEUS or flashtool? Does it actually flash and then not boot? What does it say when you flahs using the flashtool?
But again, if the flashtool isn't working, you are going to have to use SEUS to get back to scratch. Run it as Admin...let it boot up and do nothing to the phone for at least 2 minutes. Do not swipe or move a thing....let it settle down.
Some of you people who ask for help really don't provide much information at all.
To me it looks like a wrong firmware problem... version you have installed isn't the same as kernel.
I would flashtool....root....turn off phone....SEUS full reflash....

When the flash finishes up it says to turn on the device and the start up may take some time, Ive let it sit for hours and still nothing. IDK what the hell is wrong with it.
K well I give up. Ive tried 3 more times using a cpu with xp and still the same thing.
If any one else has had this problem please let me know.
looks like the faulty motherboard issue to me, some users are experiencing this problem, if you have warranty get a new phone if don't then i don't know what else can you do :/
Great. I have no warenty so looks like I'm screwed.

[Q] Xperia X10 OS Reinstall failure

I have been trying to reinstall the OS on X10 using the Sony PC comp and also tried with the Sony Update service but get stuck at the same stage in both.
Everything goes ok till downloading the files from the internet i.e preparatory stage. It then tells me to remove and turn off the phone and reattach while continuously pressing the back key (IMAGE 01). It says to select USB connected and mount the SD card. I am following the instructions to the T but nothing forward happens. I have repeated it over 50 times but no reward. It just does not go into the next stage of installation even after waiting 30-45 mins but sends out an error (Image 2)
I thought maybe xrecovery, OS Monitor, superuser, Antivirus might be interfering so I removed them too. Has rooting got anything to do with it?
Searched Google and here but did not find anyone who has encountered like this.
Any suggestions or solutions would be highly appreciated.

Question Sony Companion UEUpdateFailed UE_200

Hi all,
I tried several times to repair my phone with Sony Companion after flashing a different region. Unfortunately, it doesn't work, as it stops with the message to prepare the phone and need more than 50% energy. If I try to repari it with the flash mode, I get following error:
UEUpdateFailed UE_200
Click to expand...
Click to collapse
As it seems that I am not the only one with this error, I started this topic.
Does anyone have a solution for it?
At risk of breaking things further, have you tried Newflasher?
Newflasher works, I did also an update with it.
But making a clean install with Sony Companion doesn't work.
months ago i've tried the Software Repair with Xperia Companion (on 5 II), but it doesn't work. The phone shut down during the process, and of course everything fails. The same with 10 III.
I think SONY seriously needs to upgrade Xperia Companion or, why not, give the community another software for updates/repair on Windows.

Question Broke my Sony Xperia 1 III trying to root it. Any help is gratefully received

Hi guys
I followed this guide for unlock bootloader and install magisk: https://forum.xda-developers.com/t/...re-and-gsi-rom-flashing-without-twrp.4344371/
I don't blame the author of the guide, it is my device, my responsibility, my decision to attempt this. My fault.
Everything was going great, I unlocked the bootloader successfully and my device wiped and rebooted. It boot back into android, I turn off, go to fastboot mode, and try to flash magisk img file I made earlier in the guide. It says success, then last step of the guide is to wipe with fastboot -w. This fails, says cannot wipe metadata. Reboot, now my phone says "your device is corrupted and cannot be trusted and will not boot"
No idea what to do here, so i try to use Xperia Companion to restore. But it refuses because it detect bootloader is unlocked. Now I try to use NewFlasher to flash firmware from XperiFirm, this starts off fine but then NewFlasher reaches this point
"Extracting sparse chunk super.040"
"Uploading sparse chunk C:\temp\xperiafirmware\flash_sesson_super.0.40"
"download:03b4c9c"
"ERROR: TIMEOUT: failed with error code 997 as follows:
Overlapped I/O operation is in progress
I have tried to do this with another computer, I have tried 2 other USB cables, I have tried another firmware (originally tried the latest version with open carrier but also tried with carrier specific one) I am now running out of ideas to try.
I can get to fastboot mode or flash mode, but if I try to boot OS it says "your device is corrupted and cannot be trusted and will not boot"
Any help or a point in the right direction would be much appreciated
Thank you so much in advance
Last week that happened to me. As long as you can go to fastboot you're good. First is relock the bootlaloader via fastboot then repair it using xperia companion. Or if you can download the firmware via xperifirm then flash it via flasher.
Also make sure that the PC your using has both an Intel CPU or AMD CPU and a full windows install not that cheap windows store only crap..but one you can actually install windows .exe files and make sure you have installed the Xperia drivers by turning off driver verification...o tried without and my 2 in 1 couldn't find my phone for Xperia companion nor the other flashing tool...
Thank you @Mangtas_666 @Ainz_Ooal_Gown I have no idea why but I just couldn't flash the UK firmware, tried 2 versions but neither would flash with NewFlasher. kept getting these timeout errors. But then i randomly decide to try the US firmware (XQ-BC62 instead of XQ-BC52) and it worked 1st try. My phone is up and running again!
The strangest part, when it connect to the internet and I apply all my UK settings, it somehow change back to XQ-BC52 on its own. It is detected as such in "about phone" now even though I didn't re-install firmware since fixing it with the US one. Oh well, i'm not going to complain, I'm just happy it's fixed. Thanks for replying
