Xperia SP C5303 Bootloop Help - Xperia SP Q&A, Help & Troubleshooting

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

If you follow this guide i made: http://forum.xda-developers.com/showthread.php?t=2476938
You will recover your device with an official Sony tool
After that you can try it again. Since im not into flashing custom ROMS at the moment i cant help you futher with it ( just being honest )

It was long... BUT IT WORKED !!

[Q] Help: Motorola Milestone Stuck at Motorola Logo on boot

i rooted my milestone a few months ago (g.o.t.) and recently i tried to install the shadowsmod gingerbread rom onto it. when i restart the phone it stuck at the Motorola boot logo (M). i can enter recovery mode and do a factory reset but the problem still remains. maybe i just have to flash the stock sbf to fix the issue but the problem is that my battery is almost deplete and that the phone wont charge itself so if i enter the bootloader it'll say: battery Low cannot Program. please help me, i searched hours long for solutions but nothing worked.
Thanks in advance
Srinath
Have you done a nandroid backup? If so, you must be able to nandroid restore the Milestone, if you still have some batery left. It is usually pretty quick the restore. And if done correctly, your "stone" will be back. Next time flash the phone only when you have a fully charged battery. That would be what I would do.
Hope it helps.
YESS thank you ! i am so stupid : i DID do a nandroid backup but for some reason i forgot it! it works it really works! thanks alot your a lifesaver
Glad I could help . But you went lucky. As soon as I send the reply I though to myself, if the flash is done through .sbfs it must erase the open recovery partition. So, no nandroid restore option. But I guess you where trying to flash the roms from within the open recovery itself. So that way i believe the open recovery partition still remais untoutched. Not shure though.
Anyway, it still worked. And that´s the most important thing.
See you around.
normally if you have this problem after install a new rom, you just need to clear the cache / dalvik cache and it'll fix it
i have the same problem but i installed a rom with Droid 2 recovery bootstrap. before flashing i maked a nandroid backup but i cant get acces to restore. anyone can help me?
just reflash stock firmware. i have Droid2 Global and haved same problem but, reflashed stock firmware, root and after install bootstrap recovery, worked for me. may be helped you?

[Q] Bootloop after flashing Achotjan-Semc-Debrand-Engine-V1.0_Final_E15i

Hello xda developers,
I have searched in your whole forum but i can´t find a solution for my problem.
I´ve rooted my x8, installed xRecovery, Rootexplorer and installed a android 2.2.1 custom rom. Everything worked. Then i decided to install the Achotjan-Semc-Debrand-Engine-V1.0_Final_E15i. I did a factory reset, wipe cache, dalvick and battery stats. Then i flashed the rom.
Problem: While rebooting i got a bootloop. Even worse: i don´t get back in the xrecovery menu !!! I pushed the back button nearly 100 times but it doesen´t work.
Question: How can i get back in the xrecovery ?
Because you need nAa kernel and you need to flash the ROM in CWM recovery.

Can i fix this or is this phone forever broken ?
Did you try to repair your phone via PCC or did you use SEUS ?
I was able to fix a bootloop with PCC

[Q] [HELP]Xperia T Bricked

Alright, Here's the scenario : My phone was working fine, I tried installing the DoCoMo SystemUI here and the All-in-One add-on, Installed normally, cleared cache & dalvik, rebooted, the boot animation plays for a few seconds, it freezes and then the phone restarts. I tried clearing data, then re-installed the JB rom, then i cleared System, Data, Cache, .android_secure and even SD Card (basically everything except ext. SD) then installed CM10.1 from recovery and still the same thing, Bootlooped at boot animation.
And the phone won't charge offline normally, it charges for a while (like 10 seconds) then it starts itself and get into the bootloop.
As formatting everything and installing again didn't help, I don't think FlashTool will, but I'm downloading the 9.1.A.1.140 FTF now and I'll try it tomorrow (slow internet).
Is it possible that the phone is hard-bricked and can't be rescued? If not what else can I do to bring it back to life?
If it was hard bricked it would not boot at all, it would be totally unresponsive (Just like a brick)
Were you on cm10 before?
If so you you cant install those stock based add ons, you should be able to restore your backup. What happens when you do that? (You did make a backup didnt you? Always backup just in case it f**** up!)
If you were not on cm10 before then you need to have an unlocked bootloader to flash cm10, make sure you have unlocked.

I don't have a backup, but would it matter because it only backs up data, system, cache, and .android_secure and I formatted all of them and did a clean install of both official JB and then CM10.1, Same thing for both. That's why I'm scared, I did a clean install but it still bootloops. (OFC my BL is unlocked)

You have yet to tell me which rom you were on, informtion like that will help me help you. Please answer all my questions
which kernel is currently installed on your phone?
YES! FlashTool has fixed it!
And I was on stock rom and DooMKernel at the moment of installation.

I'v done this several times, by cwm and by stock recovery - same result. Finally I've installed branded rom and it's working perfectly to the moment I wanted to uninstall operator apps by titanium backup. Sometimes at the finishing of uninstall phone reboots... but working.

yeah n between uninstalling system apps system boots but thats not a problem as those apps which you wanna remove get removed even if your phone gets rebooted
Did you also wipe dalvik? Try to flash a stock (old) firmware via odin and do this steps.
1.reboot to recovery
2.wipe data /factory reset
3.wipe cache partition
4.reboot
İt has to boot normally in 2-3 minutes. İf doesnt tou gotta make a Jtag operation which you cannot do without the RiffBox.

You should flash a multi package firmware when rolling back from custom roms.XXKPH is one such rom,then you can flash latest update afterwards.Cache etc never matter for me

Bootloop, cannot flash a new ROM

Hi everyone,
I really need help, I have tried everything I could think of and nothing works. So if someone more knowledgeable could help me, that would be great.
I followed the instructions in this thread https://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343
and everything went ok until I flashed a new ROM.
Current situation : Bootloop when I power up. Can still access TWRP recovery. Phone is recognized by flashtool/xperia companion/emma.
Tried to flash a new ROM with flashtool->error (can't read byte value), I tried de/re-installing flashtool and the drivers and different ROMs, always the same result
Tried to repair with xperia companion->error, can't complete
Tried emma->phone is locked
Tried sideloading ROM to flash through TWRP-> error
I don't understand how, even if I flashed a corrupted ROM, it could prevent me from flashing a new one over it?
Any ideas?
Thank you.
You can try xflasher tool as well.
https://forum.xda-developers.com/crossdevice-dev/sony/dev-xflasher-command-line-flasher-t2986634
But be warned - this is for more experienced users. I never tried it but it sounds like to be very powerfull.
For questions ask in xflasher thread... I never used it up to now...
But sometimes it helps to wipe cache/dalvik AND data from TWRP. Yes - all your data is away then!
Not nice to loose data but a bootable phone is even better...
Or flash again full ftf via flashtool. Wipe APPS_LOG/USERDATA (check boxes) but do not flash simlock.ta (if its there) !!!
This will wipe all your data as well..... While flashing, say NO to "fcs-script" popup.
. .
Thanks for the replies.
I tried different USB cable/port, no change.
I always selected to wipe everything in flashtool. I just got the phone so there was none of my data to save.
I will look at xflasher although, as you said, it looks intimidating...
