Xperia SP C5303 Bootloop Help

Hello xda community,
First I have to say I'm french so sorry for my english
I really need your help. I've bought that phone TWO days ago and it already doesn't work. Lemme explain:
- I used DooMLoRD method to Root and install CWM (C5303 model with locked bootloader).
- I installed Xperia Pureness. Wiped System, Cache, Dalvik... It worked fine.
- But i after a few hours Home button didnt work eek so I decided to reflash the rom to reload the System UI. As I used to do with my HTC Sensation, i only wiped dalvik cache and cache for the 2nd flash (ERROR). I realised after have rebooted that i should have had wiped System too.
- It didnt boot since this 2nd flash.
- I've been trying to repair it for this ENTIRE day, nothing happens (pressed red button 5 secs, 10 secs, also tried to reflashed stock .254 ftf with FlashTool...), still can't access Home...
Can you devs find a solution? I really need to repair my phone, bought it 2 day ago :crying:
PS: it doesn't matter if i loose data on my phone

Reflash ROM and dont wipe cache and dalvik If that does not work you need to restrore the backup you made, or you can restore it with my easy restore guide i just made

Thanks for the quick reply.
I'm always on bootloop, so can't even access CWM, is it still possible to flash a ROM, or access CWM? I've tried something like 10 times to reinstall stock ROM with FlashTool, still stuck at bootscreen.
I didnt think about making a backup

Need help bricked phone :(

i recently flashed the eXistenZ Ultra 2, and im sure i did everything fine, after flashing the rom in recovery and flashing suprsu and wifi fix, i powered off the phone, and powered on but sony logo has apeared until now , and welcoming`s sounding 999..times. i cant turn it off, or i should say i cant do anything.
please help,

After flashing ROM and the fixes you should flash the 12.1.A.0.266 Firmware with FlashTool!
If problem still persists:
http://xda-university.com/as-a-user/how-to-recover-from-a-bootloop
Take a look at this site A recovery would be quite useful, but I think the kernel of eXistenZ ROM has one. If not, you'll find one in the development section. Otherwise, use the ADB as solution.
Good luck

Thanx for the post!
I used force shut down and then flash the 254 rom, and did all those things, and the problem occured again.
does the recovery software have to be the touch recovery? I use CWM v6 that enables with volume +.
and i use SuperSU fix.zip rather than superUser.zip and generally i flash rom, supersu fix.zip and wifi fix.zip. i flashed those three, before first booting, do i have to boot first before flashing wifi fix.zip?

I think you need to flash 12.1.A.0.266 instead of 12.0.A.2.254 after flashing ROM. You could also wipe data, cache and dalvik cache, reflash eXistenZ ROM and SuperSU fix (or SuperUser but SuperSU should be ok), shut down the phone with the option in recovery and then flash the 12.1.A.0.266 with FlashTool.
It doesn't matter which recovery you take. Use the one you like best. I'm not quite sure, but to go sure, please flash the wifi fiz.zip after first boot up!

thanx again,
i flashed the 266 kernel before the first boot, and the rom runs correctly,
but ive got some new problems:
1. performance, when i click on performance, it closes unexpectedly and says it has stopped.
2. i used go backup for backing up from data in 4.1, but in this rom i restored my apps,the apps installed correctly but goBackup says the data restoring successfully finished , but the data didnt restored, by the way at the time i backed up from my apps&data, i swapped memories with that linux code that this forum did.

You're welcome
1. Do you have SuperSU installed? On AOKP ROM I'm running it asked for superuser permission for ROM Control (the control center implemented in the settings of the ROM). Maybe it'll ask you if SuperSU is installed. Otherwise, because it is after the first boot it needs to rebuild cache and so on.. If problem persists after reboot, just use an other clock speed controler (No-frills CPU, SetCPU..)
2. If you did that at the same time, maybe Go Backup didn't really backup your data. Try again, if it doesn't work and if you have a nandroid backup (backup from recovery) you can go into recovery, then to advanced restore and restore data. Otherwise your data is unfortunately gone I think :/
PS: I prefer Titanium Backup

[Q] Bootlop after failed wiping data [Solved]

Hi guys, i need your help..
I was tried to install a custom ROM and i use CWM v6 to install it (i'm on stock ROM | JB 4.3 | FW .205 | locked bootloader | recovery installed : CWM & TWRP), first step i format the /system and is successfull, then the next step wipe data/factory reset but i get stuck process on:
--- wiping data ---
clear /data done.
clear /cache...........
I don't know why, but i've been waiting for 20 minutes and still stuck like that than i decides to turning off the phone with tiny button at bottom of battery (not power button), i turn on the phone again and then i've got bootlop ( what.... where is my recovery ) i didn't noticed the recovery still in there because there is no LED notify when i turn on the phone, just SONY logo :crying:
Is that happen because wiping data didn't completed and causing my recovery also gone ?
So what should i do ? can i get the phone back again ? I have the stock ROM backup on my sd card and on my laptop because before i try to install a custom ROM, i've created current ROM backup with CWM.
please help me guys..

You wiped /system so your recoveries are gone.
On older Recoveries using the wipe to install new rom can take ages so just leave it and eventually it will finish, latest version of Philz (in Bagyusz/Nexus ROMs) seems to fix this issue.
Use DSSMEX triple recovery and use philz not cwm as its a much nicer recovery (but the clean still takes ages as its an older version)
Use flashtool to flash stock rom and start from scratch to re-install custom rom.

Oh god, i don't know about that, because this is the first time i've got bootlop..
Where is i can get the latest version of Philz, would you like to give the link ?
Triple recovery ? maybe 2 recovery is enough
Flashtool, okay i'll try to save my phone..

You have bootloop because your phone is essentially empty of any OS or recoveries.
Flashtool to stock, find dssmex triple recovery and install that in stock when rooted, load into Philz, clean to install a new ROM and then just wait, it will take a while usually dont worry unless it takes over an hour.
Then flash the custom ROM of choice.

Can I know what Custom ROM are you trying to install?
Sometimes wiping could take time, and I am not sure why. If happens again in the future, just let it be.
As you are using LBL, I am unable to elaborate nor understand how recovery has gone. (WARNING: FOREIGN LANGUAGE) Recoveries for LBL are stored in the ramdisk OR the FOTAkernel. This is due to the fact that Xperia SP does not has an exclusive "recovery" partition in the rootfs. I dont know if wiping data would trash them.
You can easily recover your phone by flashing a stock ftf. You may follow this guide: http://forum.xda-developers.com/showpost.php?p=56717587&postcount=4

Thanks for your explanation sir :good:
Flashtool to stock means i need .ftf file to restore the stock rom ? is it possible to restore stock rom through nandroid backup file that i've created using cwm ?

Well, the problem is solved. My phone back again and a custom rom has been installed.

Dont use flashtool..... Youre wasting time.
Just flash Williams kernel using fastboot and flash the custom rom you want.....

A cry for help

Hello all,
Firstly I would like to thank all the great people here, I've been struggling for hours with my dead Xperia Z and the amount of dedication and support I've found so far across all the members here is really impressing.
Let me first illustrate my case.
Firstly, I came here to root my phone and install a custom rom ships with Android N 7.1.2 (Resurrection Remix), I did went through all the newbies/how to threads and I did successfully ended up with Android N on my phone
Unfortunately, the device was not working probably in case of incoming or outgoing calls. No ringtone (already selected from Settings >Sound - played and heared), while in call it keeps ending the call unexpectedly, sometimes it feels very laggy that I couldn't even tap on anything. So I decided to give up until I found another rom that ships with Android N (XOSP), after successfully installing the rom, it starts out very smooth and I tested everything and it was ok, until yesterday the same issue still persists plus my device mic is not working no one can hear me while I'm talking neither from a headset mic nor the device mic. Finally I gave up and decided to rollback to the old lolipop stock rom.
Here's comes the current problem:-
1- I did flash 10.7.A.0.222 Customized MEA using flash tool and it's flashed successfully.
2- I'm now stuck with a dead black screen after sony logo.
I tried everything, changed the flashtool version, downloaded other ftf kernel file, used Xperia Companion and non of them worked for me. I did also tried what's listed in here https://forum.xda-developers.com/xperia-z/general/disaster-recovery-getting-z1-zu-z-zl-to-t2229250
I only can boot into fastboot or flashboot mode
I cannot copy files to my phone as it never appears as a storage media in my computer.
Any help will be much appreciated
Sorry for the long post

I never had this problem before, but have you try other ftf with lower android version like KK?
I see this problem on someone, everyone of them had this problem when they try to revert back to stock LP from N. Then someone suggest to flash KK ftf. You should try this if you haven't try this.
Sorry if my English is bad.
UPDATE:
when the first 7.0 nougat custom rom came, I'm on 5.1.1 rom with XZDual recovery. I made a backup for this rom and flash the 7.0 N rom only for trial then revert back to stock 5.1.1 that I backup before. Chippa's rom always came with latest built-in recovery so when I upgrade to nougat rom the XZDual recovery also lost (I don't have FOTA recovery, lol).
The step I made to revert back to stock is to do a FULL wipe of the phone (cache, davlik cache, data, system, AND internal storage), not a regular full wipe (without internal storage).
I put my backup stock rom file to my external sdcard (because the internal storage got wiped) and begin to flash, BUT NOT reboot into system, I reboot the phone to recovery instead (because I think the 5.1.1 rom works better with old TWRP so I reboot the phone to recovery first to get the old XZDual recovery).
After phone enter the old TWRP, I do a FULL wipe (cache, davlik, data, system, internal storage) once again to make sure everything OK, then flash the stock rom once again.
aand... it works. I did it 3-4 times to test new build of 7.0 n rom and never have any problem of reverting back.
But, I never test this method on newest 7.1.1 rom or 7.1.2 rom.
since you can't boot on LP rom, then try to flash KK rom.
Just install phone driver, flashtool, and download the KK ftf.
I'm sorry I can't provide you the full instruction because I never had this problem before, but you can search for this on N rom thread (the rom developed by Chippa). There is a guide made by someone on that thread.

Install Stock Firmware (JB 4.1.2) without Odin

Hi everyone, I'm here because i have problems with my phone and i want to fully restore. To do this i would like to install a new ROM, but from what i've seen, to install a ROM is necessary to have the stock JB 4.1.2 on the device, while i have CyanogenMod 11 (4.4.4) running.
This wouldn't be a problem if i could use Odin, but apparently my USB port has something wrong, and i cant connect my phone to any PC, so i cant flash in that way. Luckly i can access to the custom recovery (CWM), so i 'd like to ask if there is a way to flash the stock firmware via CWM.
Instead, If I can install a ROM starting directly from CM11 without restoring stock JB, or if i'm missing something important, let me now, i would appreciate a lot
Thank you in advantage. (Excuse se for any misspelling, I'm not English)

What kind of problems do you have?
If you can access CWM recovery there's no need to install stock in order to flash a new ROM, just be sure to wipe caches and data before installing the new one to avoid related bugs; and you will probably need to update the recovery to TWRP if you want to flash one of the most recent ROMs
It's always recommended to create a backup before everything else.
Peace

Hi, thank you for then anwer Well, it would be a long list of problems ^^ The biggest one though is the fact that if I'm in AeroMode everything works as always, sometimes bugged but nothing exceptional, but in the moment i switch AeroMode off and digit the SIM pin, the phone turns off and then enters in a bootloop(vibrating every 1 minute like before entering the main window, but it remains stuck) that is solvable only pressing for 8/10 secs the POWER button and restarting it. I can't have a phone which is not able to make voice calls :/ Back to the problem, so if i'm not misunderstanding anything, I dont need to reverto to stock and then reflash the new ROM? Because, for example, in the main page of CM13 it's written:
ROM Firmware Required: Stock + CWM compatible with KitKat
and that's the origin of my post... But in case, which wipe should i do? Dalvik + wipe data/factory reset?

OK, the thing is that you need stock + CWM at minimum, it means you can't install it if you are on gingerbread; but if already installed something higher than 4.1 you can go from there.
First create a backup then wipe cache, wipe dalvik, factory reset and install your preferred ROM

Ohhh, that makes sense.... Ok, so i will wipe what you said and flash the new ROM! You saved me a lot of time, thank you so much!
