Bootloop after flashing with flashtool - Xperia Z4/Z3+ Q&A, Help & Troubleshooting

Hi guys,
I have a strange problem after attempting some upgrade/dwongrades with flashtool. I tried to upgrade my phone to 7.1 version using flashtool (from 7.0). Downloaded ftf file and flashed it. After first start up and those "preparing " thing, it gave a flash of "SIM inserted , rebooting" message. Now it keeps looping on this. Everytime, it attempts to boot, this message appears and phone goes into reboot loop.
I tried to flashback old versions (6.x, 7.x). But , all of them now going into a reboot loop. (older versions are not showing the SIM error, but just rebooting). Doesn't looks like a SIM tray related error, as I tried to boot even without any sim/mem card.
Any pointers? Help?

Update:-
After flashing with Emma (Sony Developer site flashing tool), the phone became stable.
Maybe I should use some wipe options on other flashtool. I didn't select any wipe boxes in that. Just loaded FTF file and flashed.

Flashtool loader.sin errors

Hello guys,
Someone on this forum recommended to use CWM recovery to install existenz 4.0.0. When I tried to flash it it gave me symlink error 7 and I accidently rebooted. Now the phone is stuck on sony logo. Using the reset button didnt work either because it would just reboot. When connected to charger it shows a constant red light. When I use PC comp. to repair phone, it won't recognize the phone for repairs. Flashtool on the other hand does recognize the phone, but when trying to flash a stock Generic LTE ftf is gives me processing of loader.sin is finished with errors and then error flash. aborted.
Phone is C5303, FW was Generic LTE (205). System has been wiped by CWM before the symlink error.
Battery percentage was 35% at the time of using CWM recov.
Any help would be appreciated, especially as I'll be leaving for 4 weeks and I won't have acces to my laptop
Cheers
Is it Looping Again Again On the Sony Logo. If That Is The Case Either The Kernel Does not Match with Rom or The Boot Partition isn't Wipe Properly try Flashing The Kernel That Came with Exisentz or try Doomlord Kernel (depends on the version) Im Sure That will Work.

Thanks for the advice, but I managed to get the flash working (the laptop I used needed 23 driver updates so.....)
It's back to working

[Q] HELP needed!! Phone possibly bricked!!

Hi Guys,
I was trying to update my Z1(C903) to Lollipop, but weirdly I wasn't able to boot into my recovery to install the pre-rooted rom. Every time i tried to enter into recovery, the phone would just vibrate and then proceed to boot the OS(I have dual recovery installed). I tried to reinstall the recovery but to no avail so I tried to flash stock FTF (14.4.A.0.157) but the process was struck at "flashing data" for a long time and I idiotically unplugged the phone after couple of hours!! And now my phone boots and i see the sony logo and next screen says "Software update failed. Connect your phone to computer and try again" And I'm unable to flash any FTF and the process still gets stuck at "flashing data".
Help me out guys as I badly need my phone for work!! Thank you!

you definitely can't enter recovery now, cause that partition would have been wiped now. try flashing again.

Xperia SP: Stuck In Bootloop After Flashing Wrong File

Xperia SP stuck in bootloop!!! Please HELP!!!
Ok here's the short story.
I made a mistake and accidentally flashed the wrong zip file and now my phone is stuck in bootloop.
It is Locked Bootloader C5303
I have a twrp backup of my previous rom which worked fine but i am not able to access any recovery, the phone just stays on the sony logo and then crashes.
I have tried fixing my phone with pc companion (which has worked before) but now when i try it the software says the update service engine for my phone is not available.
I have tried the androxyde flashtool to reinstall the stock firmware but the flashing stops and says that it has completed flashing system.sin with errors.
I don't know what to do, is there any way of restoring backups without accessing the recovery or maybe there is a way i can access the recovery.
When i hold the volume down button a green light comes but nothing else happens.
any solution will help, i don't mind returning to stock either.
Any help will be eternally appreciated.
Thanks

Give me some details
1. Windows version(7,8.1 or 10)
2.Flashtools version
FYI, if you are on windows 8.1 or above then you have to first disable driver signature verification and then proceed with installing drivers.

C9603 Bootloop after using Flashtool

I'll try to give as much information as I can here.
I wanted to downgrade Android from 5.1.1 to 4.4 as Lollipop in general was giving me so many issues it was making my phone unusable. So I looked up as much as I could, downloaded the latest Flashtool and the 14.4.A.0.108 Central European 1 version of KitKat.
During the flashing process I did not select a wipe of userdata as I wanted to see if I could keep what was on my phone without having to do so. I also checked the box to wipe applogs, as I wasn't sure what that was and 'what was the harm?' I thought. I couldn't find anything about what that actually was, so I don't know.
Now it is stuck in a boot loop, but thankfully phone can be turned off. Flashtool is giving me an error when I try to flash it again, so all further details are below. This was my first time using Flashtools and doing anything of this kind, so please try to be nice. Thank you.
- Customisation Version 1276-4318_R2D (Not sure if this is relevant)
- Able to enter Flash Mode and Fastboot
- No recovery mode, Stock ROM with developer options but I think it has a locked bootloader (not really sure what this means)
- No SD card, but I backed up what I wanted to keep on the PC.
- All drivers for phone are up to date on computer, but Sony PC Companion (including repair mode) requires phone to be on and connected I believe.
- I tried to flash it again but this time wiping everything, except Flashtool gives error of 'Processing of loader.sin finished with errors' and then aborts the flashing process.
EDIT: Finally successfully flashed 4.4 to the phone.
Now I have a couple of new problems.
1. The screen keeps randomly clicking/moving itself.
2. My back/home/etc buttons at the bottom of the screen still aren't responding quickly, and I get quite a bit of lag using them.
it is due to dirty flash, I guess, reflash with wiping selected and it should be OK

HELP!! Le2 x526 Not booting Up, nor Charging

Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.
Thanks in advance
Try to check your USB cable, most of the time charging issue is due to cable

Cable is ok. I have another Le2 and it is charging with that cable very well
I am facing same problem. How you solve this issue? Blue led blinks after flashing any rom and bootloop.

I also have the exact same problem. Phone started rebooting as soon as it booted up. Somehow i managed to unlock the bootloader, but to no avail. Can't seems to find any rom which can boot up. So practically i have a bricked device with trwp. Formatted the system and other partitions with twrp, flashed many roms. Still the result is same. Bootloops.
Hi,
try to to reimage your phone with QFIL from this site:
https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Brother same thing happened to me, a week ago. I cant say about your problem but my problem was due to faulty power button. Actually due to that reason my phone actually kept restarting itself. It showed red light blinking while charging and wasn't able to bypass the optimizing app screen. I also thought it was a software issue but actually it wasn't. I spent about 2 hours figuring out what the actual problem was. The problem was: As we know when power button is hard pressed for about 10-15 seconds it reboots itself.
Although the repair shop guy didn't put new power button but he added a tiny piece of paper in between the power button and body housing to prevent the issue and voila the problem was solved.

Hi, Thanks. I actually did that first, flashing through qfil the same rom. it helped me to go to settings after umpteen attempts to go past language selection screen, and i was just able to oem unlock and enable usb debugging (actually after a 2nd partial failed flashing). the phone kept freezing within seconds of booting up. Now After i unlocked the bootloader and installing twrp and flashing many roms thru twrp, i am still having the same problem of booting up and freezing at start-up. cant flash again through qfil, as i will again loose the unlocked bootloader and twrp.
At least , now i can try different roms to see which can unbrick it. last one used was the twrp flashable rom based on eui (small eui by aurel) but it also freezes on language selection screen or beyond.
I am running out of ideas, lets see.
2nd partial failed flashing? any issues during the flash process? i had some issues when i used usb 3.0, 2.0 worked fine for me. If you have also charging issues stay in twrp and let the phone charge properly, its slower but should work fine. You can try to flash the 21s bootloader with modem, maybe it will boot properly. But try it only when you are able to enter the fastboot mode, longpress volume down and power for 10-15 seconds, if that is working you should be able to flash twrp via fastboot and you can experiment a bit. Try to find the chinesse twrp 3.0.2.0 and try to flash the stock 21s version. Should be also an image file, in standard twrp go to install - image, after selecting the image file click on recovery and install, after installation go back, reboot, recovery. Copy 21s to storage, wipe data, cache, dalvik and flash it, chinesse twrp will skip version check and will let you install the stock image, after install reboot but click on do not replace recovery button - this will keep the chinesse twrp installed.
If nothing helps it can be only a HW failure, maybe the power button, try usb 2.0 port during the flash process, i had issues with 3.0 on my pc, if that doesnt help.try a different cable, no more suggestions, sorry.

My phone has been flashed multiple times by qfil method. And always it hangs at initial setup (so it boots up, but hangs at language selection or further up screens, before setup can complete and launcher could be loaded).
While trying to flash again with qfil once it stopped at 25 percent (because the battery went dead). Charged the battery and booted up the phone, and i was surprised it booted up. After 2-3 attempts i was able to reach the launcher screen and immediately enabled developer options and oem unlock / usb debugging. Only had few split seconds to do this and the phone froze again. After that i installed twrp and hence treying different roms. Most fail at setup.
Just tried MIUI 9PRO ROM. It also froze at setup multiple times, but once i was able to complete the setup and miui launcher is up , but it reboots or turn off the phone just after that. So cant do anything with the phone. Unsure of whether a newer bootloader will help in these freezing issues as i have been able to boot up at least in some roms only if for few seconds. Will try to tinker the settings of miui rom (if the phone let me do it before freezing/hanging). Lets see. Thanks for suggestions. More suggestions welcome, because i am still unsure weather this is a software or hardware related problem. I am guessing that it may have something to do with Google security as earlier i was getting msg that phone has been wrongly resetted and needs to verify with Google (but i couldn't get a chance to use the same account, as phone kept freezing at setup).
Did you fully charge the battery, if not let it fully charge in twrp. Flashing the roms in twrp works everytime or do you see any errors? Before you flash anything disconnect the usb cable.
---------- Post added at 09:54 PM ---------- Previous post was at 09:47 PM ----------
Try to flash the 21s bootloarder with modem, one zip using twrp. Go to fastboot mode and wipe modems. fastboot erase modem1st fastboot erase modem2st. Put the phone to flash mode and reimage with qfil. Before you do it write down both imeis, you can find them also on the original package on the backside. Also try to remove all sim cards from the phone and try a different cable. If nothing helps, hw issue, maybe the power button mention earlier in this thread.
After reflash skip everything at setup and reset phone to factory defaults. OEM is already unlocked, you dont have to do it again.
I have charged the phone fully before any flashing after that error. I can flash the phone through twrp without any error msg. The phone boots up most of times in various roms but hangs at or after the initial setup screens show (like language selection etc). Flashed the modem+bootloader, success, but it showed bootloader version as 20s (not 21s). Tried the commands u mentioned to erase modems, it say error failed, no such partition found. I had checked the partitions with parted and 56 partitions are there including the modemst1 & 2.
Now re flashed via qfil , did as advised but again the same problem of hanging / freezing at or after initialization screens of various roms.

Yeah sorry i screwed the command its fastboot erase modest1 modemst2, my bad.
Just now i was able to complete the initialization (setup screen) of sparse image india rom. I can reach the launcher and settings for few seconds before the device freezes or reboots.
So the same problem , with which i started, the only good thing is that i have been able to set oem unlock to on, so that i can flash trwp and various roms (but all fail with the same freezing issues)

So you erased modems and reflashed with qfil right? If so i assume its a HW problem. Try the fix with the power button, i ran out of ideas
Last thing which can help maybe: https://www.youtube.com/watch?v=LH3VOIlLfvo&t=135s
Download 21s stock image + the chinesse twrp, links should be under the video, i think so, or look somewhere in the forum for new links. Try to reflash the 21s, some people reported that freezing issues were gone after installing the latest EUI. Basically you can do the same after QFIL reflash but you need enough time to copy the ZIP file as UPDATE.ZIP to the internal storage and run the local update via setting, system update and local update, i hope that TWRP will work for you, just follow the video tutorial.

Did that also, the same problem. The phone freezes after the os is booted. I was wondering what is that isnt touched by flashing ( in download mode or fastboot mode or through twrp). I may need to tinker that. The roms are all fine in the sense they all stop at the same points. Something in the phones partition, which isnt touched by flashing? (There must be, as i flashed with qfil, the oem unlock remains, the bootloader didn't lock, and it remains unaffected by re-imaging)
Try this, maybe it helps:
