Sony Logo And Reboot - Sony Xperia XA Ultra Questions & Answers

Hello,
Whenever I try to turn on or charge the phone, it keeps showing the sony logo and restarting the phone. I tried the Sony Companion program, the blue light is on on the phone, but the program does not progress. I changed the battery as the problem might be in the battery but the result is the same. What should I do ? Factory operating system is enough for me. Can you share with me what I should do and related topics? thanks. operating win11 and phone is all stock

[Q] constant reboot after Titanium Backup app uninstall

Hello.
I've a Sony-Ericsson Xperia X10 with the lastest official ROM (2.3.3), rooted with Flashtool.
I've tried to uninstall a ROM app (Wize Drive, a GPS app without interest) with Titanium backup (lastest version). It annouced me the phone will restart 2 times to perform the uninstall.
But actually the phone just reboot again and again.
If plugged on power it restart itself. If unplugged, I must start manually (power button) and after a few seconds it powers off.
The cycle is Sony Ericsson logo, and after that a logo on black screen: a phone with a blue arrow and a yellow caution triangle for a few seconds. And it reboot again.
This loop is endless, I can't use the phone anymore, so please help me !
Thank you for your help.
Repair your phone using PC Companion, SEUS or Flashtool
Thank you for your answer.
I've tried with Flashtool and the phone is connected when I plug it but disconnect itself very quicly when reboot, so I can't access to flash tool function (they stay grey the 10 seconds before the phone reboot). Sony PC Companion lose the phone quickly, too.
Update Service has accepted to perform a full restore.
Now, I've to boot it again. When I want to start, I've a blinking red LED. So I plugged the phone but I've a loop again: SonyEricsson on black screen and when the battery logo must appear, the phone reboot... Seams to be a battery trouble, I think it's empty.
Is there a way to fix this ?

The phone don't want to boot even after a night plugged to charger. Just this damned red blinking LED...

My mt15i died during a system update

Hi, i was updating my phone, previously i flashed with flashtool and rooted by DooMLoRD method, all goes good and then the phone required a system update, i tried but as soon i pressed the update button the phone powered off and have no more red light, tried to recover with sony pc companion, no chance cause this program said no software for my phone. I dont know what to do, the phone was able to enter in flashmode, not in fastboot, and when i try to charge the phone to the electrical the green light is always blinking. Any idea to recover my phone?
I fixed the phone with x10flashtool and now the phone works. It's strange i have the phone charging before fixing and when the phone was fixed and started the level of charge of the battery is 2% so i think that no real charge in effect during his "died" time but now the battery charges as usual.
I flashed and rooted my phone to make it able to install versions of Android newer than the 2.3.4, but now i'm a little scared for system updates, my phone died during a system update, there's any incompatibility?

[Q] Xperia Neo won't start

Hi. My xperia Neo crashed, I tried to send a photo via bluetooth and the phone just turned off. I tried to turn it on, it appears the "SONY" screen, then the "XPERIA" screen, and then it restarts, over and over again with the same 2 screens. I searched topics, they say that I have to flash it, but I can't start the phone in flash mode, with power and back buttons, any software (Companion, flashtool) don't detect the phone. Is there any solution?
Just like death

Hi, I´ve got similar problem. A year ago my Neo V went dead (I thought so). Just for fun, I tried to connect it to PC yesterday and what happened? It started charging and after few minutes I started it (YAAAY)! So I thought It was just some bug that disapiered after discharging. So I did a hard reset, to gain factory settings, repair the firmware via PCcompanion, everything was OK until I shove a memory card inside. After that it died again. Its not charging, no reaction after connecting to PC, no reaction on ON/OFF button, no reaction for button-hard-reset, no response while trying flashing with EMMA or FLASHTOOL, nothing... Does anybody knows what to do with it or do I have to wait again until it discharge and pray it would work after that?
help
I have the same problem as you did it to solve? :crying:
