[Completed] xperia z bootloop - XDA Assist

hey guys,
i am having a problem with xperia z c6603 lollipop 5.1.1. i rooted it using kingo root and installed a font using fonter which unfortunately turned out to be some faulty font. and i was unable to unlock my phone because the font on the lock screen became too big to make any space for pattern unlocker.after all the efforts i had to reset my phone using google accounts which unlocked the phone. now the font was still the same so i had to download fonter again to change that font but this time the fonter was not working.as it works on rooted devices so i decided to unroot and then again root the cell.i was unrooting it using kingo root when it stuck in a loop .the sont logo appears and then the phone restarts. and it is not going to recovery mode i have tried everything. can anybody help me out

xperia play (r800i) stuck on ¨boot loop?¨

hello everyone.
i got a xperia play that i have rooted with superoneclick.
now i have changed some icons like battery status etc with rom toolbox
and after restarted so i could see the changes it just stuck on the sony ericsson boot text.(in a loop)
i got stock rom an all no busy box just rom toolbox pro,superuser and maybe a bricked phone.
please help!!!
note i had a lot of crashes before i restarted the phone
and i got it in christmas so i m very sad now cus its my only good phone D:
mystery cant be bricked
its not bricked i guess becausse its still charging when not trying to boot
well...
i was wrong so now i have to download a stock ftf file atleast i know what wrong
Heya
I have the exact same phone as you with ROM Toolbox Pro and Superuser as well, and I've run into the same problem after trying to customize some icons and system fonts.
I'd be very much interested in knowing how you and if you got your phone working again.
I'm currently downloading FlashTool in the hopes that I can use that to flash it back to a stock Android 2.3.
Bootloader locked, can't flash ROM
As the title said, apparently my bootloader is locked so I can't use the flashtool to flash the ROM.
I can't unlock my bootloader in any way I've been able to discover on here as I can't boot past the Sony Ericsonn logo text screen.
Does anybody know if there even is a way past this? Will paid professionals be able to fix it? Or am I stuck with a permanently bricked phone here?
Maybe one of my family's contacts working for the service provider will have an idea of what to do.
Everything went so well until I tried to change some icons and fonts, then everything just went downhill.
Thank you very much in advance.

[Q] Stuck reboot

Hello. Greetings from Canada.
I managed today to finally root my Sony Xperia J ST26a after several months of having tried for the first time.
My experience rooting devices is very limited.
I deleted a lot of bloatware put by Sony and Bell
The phone worked quite well for a while until I got "trigger happy" and started to delete more apps.
One of these deleted apps was com.sonyericsson.home.
Such app stopped working and the phone became unusable.
I rebooted the phone and it is stuck on the Xperia animation.
Is there a way to regain access to the phone? Or is it bricked?

Flash firmware by Flashtool
Sent from my ST23i using XDA Premium 4 mobile app
Thank you DPxMiro.
Your suggestion led me the right way.
I did not use flashtool. Ended up doing a hard reset of my phone as stated in: http://forum.xda-developers.com/showthread.php?t=1862664
Phone works again. :good:

How to unbrick rooted Sony Xperia E3 with bootloader unlock allowed no

Hi guys,
I really need your help!
I rooted my phone using the method for xperia devices with bootloader unlock no(Root for Xperia E3 D2203 with locked BL by nortonex) Everything was working perfectly fine for couple of months. Yesterday my phone restarted and after a minute of using it restarted again and kept doing that, basically was stuck in bootloop, but in this case it turns on, I can do something for 5 - 10 seconds then it freezes and restart.
Rooted Apps installed:
Xposed - I disabled it pressing the right key during boot up
Amplify
Greenify
Xposed modules - Sd card, OBB on sd card, App settings, Gravity Box, Gem Xperia
Link2SD
SDMaid
I also recently installed Theme Catalog by Michael Ambrosiac.
Two weeks ago I installed BusyBox installer by Stephen Stericson from Play Store to give permission to Gem Xperia to restart the System in order to change the navbar buttons. It worked perfectly fine.
I disabled many Sony apps months ago.
My PC doesnt recognize the phone. Sony PC Companion also. I cannot use adb. I managed to uninstall BusyBox but I dont think thats a problem.
I have 18.5.C.0.19 firmware.
Thank you

How to remove =>root text from boot screen on Coolpad Note 3 Lite

I rooted my phone, everything was going fine. Last night the 3 buttons at the bottom stopped working. Now I want to visit service center to fix that but as my phone is rooted, I uninstalled the KingRoot in the process to unroot. Now Root checker is showing no root access.
But one problem is still there, on boot screen it shows =>root text. And even after unroot its still there. Any solutions??

Remove root text from boot screen
Hello,
Hard reset your device. once your device is ready then download flash ROM and flush using SP tool. this trick works for me.
