[Q] Xperia S stuck on boot! - Sony Xperia P, U, Sola, Go

I need help please!
I tried to downgrade my phone from using this guide:
thespicygadgematics.com/2012/06/downgrade-and-install-gingerbread-and.html
with the gb rom from here:
thespicygadgematics.com/2012/07/root-xperia-s-lt26i-without-unlock.html
I was on this part:
Enable fastboot mode by press and hold the volume down button and same time connect the phone to the PC via USB cable (differ from device to device)
I did it and it started flashing but suddenly it disconnected the phone and now it always displays the logo, goes back dark and so on!
What do I do now?? Please help me

First do the forced shutdown by holding power button + vol down. Then try to charge battery again, just plug it in, and try to flash again. If you can't get it to charge battery try flashing again hoping it will last long enough to finish the process.

Thanks for the reply! I did the voldown+power, then plug it into the computer and did a software reset with seus. Now everything is working again

Tip for Constant-Reboot Problems

I just had my first scare with the Xperia Mini...it constantly rebooted without getting past the SE logo, SEUS, PC Companion and the flashtool did NOT detect the phone....
so what I did was...take out the battery for about 1 minute. Make sure the phone is not connected to a pc/electricity and press the power button a few times, without the batter in. Now put the batter back in and connect the USB holding EITHER the top or bottom volume button, depending on whether you want fastboot mode for kernels or CWM for restoring...
Good luck!
Probably a faulty or wrong kernel I think...

Volume UP button enters fastboot.
Volume DOWN button enters flashmode.
Just turn off phone, click one of these buttons and connect USB cable. These been always so.
Reason for rebooting might be either custom ROM without custom kernel or faulty kernel.
Exactly.
And I will add this other:
You must press the right button when Blue notification LED on left corner will come up during booting, next you will have this 2 conditions:
Blue > Fastboot
Green > Download mode (Flashmode)

U20i No flash mode.

Hello.
I have a U20i (x10 mini pro) and i installed a custom rom (sonystyle v1.1) and i wanted go to stock rom via reperation in pc companion.
The problem is that i cant enter flash mode any more. I've tryed in many ways (take out the battery , plug the cable and insert the battery with holding "back" key) but phone always boot and on the screen there is a charging battery and a yellow led
install SEUS and turn off phone on 30 sec witout USB cable, press and hold back key and then plug cable (you must hold pressed back key all times) program will tell you when u can release back key.
Still the same only charging battery icon and yellow led
Clean your USB connector from your cable, and dont forget to:
Pull of the battery for 5 sec a insert the battery, your phone must be disconnected from USB. Start SEUS and follow the steps, connect your phone holding back key.
Still nothing .
Once i entered flash mode. I connected the cable with holding back button and when the display turn on (before SE text) i pulled battery and inserted it quickly still holding back button. But when i want to do that again it aint working.

Help.! Hard Bricked after restore of NANDROID backup...!!!

I accidentally restore a backup (of my previous Z2 which was on my sd card through TWRP) on my Z2 on Exsistenz LP ROM yesterday. After that phone wont boot. Battery was .70% at the time of death. Red blinking led is seen when connected to usb cable. POWER + VOL UP doesn't give 3 vibes as intended, in fact nothing. Neither red hard reset button(Tried pressing it for >3mins). Cannot enter flash mode or fast boot modes .(tried to flash stock ROM through flash tool-failed). Only red blinking LED appears when usb cable connected.
Wierd to found when I press hard reset button while pressing POWER button it gives 3 vibes. But nothing changed.
Tried "pressing and holding all 3 buttons (power,vol+and vol-) all at the same time till it vibrates once then let go of the power button and vol+ but keep holding vol - while plugging in the usb cable this MiGHT boot your phone into flash mode" But didn't vibrate while holding all 3 buttons.
Its out of warranty period as well.

Something similar happened to me recently...wonder if this is a bug in a new release or something
This is what I did.
If you can't turn off phone, turn it off using the hard reset button http://sony-xperia.mobi/eng/sony-xperia-z2/231-how-to-do-a-hard-reset-and-reboot-a-sony-xperia-z2-physical-hard-reset-button-sony-xperia-z2.html
There's a really good guide on bricked z2 somewhere on xda but I can't find it anymore . What it said was useflashtools and flash and old ftf e.g. 4.4.4 or 4.4.2 and make sure to wipe apps_log and user_data in settings.

If you restored another XZ2 with LOCKED BOOTLOADER's backup you probably killed your phone.
Was your bootloader unlocked?
Restoring anothers TA partition kills your device because drm keys are uniq

Stuck in peculiar boot loop

I tried to flash twrp and now my phone is stuck in a 5 second boot loop.
Fastboot and recovery can't be accessed at all no matter what combination I make. vol+ power, vol- power, both +- power, hold 40 secs 60secs (useless because phone reboots in 5 secs) , all tried. Every 5 seconds it just boot loops. Help me.. I have it for less than a week. Wanted to flash only because the stock rom was giving problems such as landscape and auto random reboots.
I even tried a script which said would wait in adb detect mode, that didn't work. Guess phone rebooted before my pc could detect it. Tried installing intelSOC method as suggested in another thread, the short reboot is tough to get by.
By the way, it's an umidigi china phone.
bump.. pls help!
Hi , let your battery to completely empty , press vol + and plug usb to see if phone goes into Fastboot mode if not try Vol - and plug usb .
Both didn't work. But thanks.

Question How to save a black brick

I tried to root my phone by magisk.
After flashing a patched boot.img, it's failed to boot into system and I got a message that "the device need factory reset". I clicked yes and everything seems ok,I can boot into system. Then I tried to flash img again. So I boot into bootloader. Unfortunately, this time I got a black screen. The phone doesn't response me anymore.
I tried the software repair in xperia companion but It cannot dected my phone when I hold on volume down and plugged in it. I also tried hold on volume up + power but nothing happened. Hold on power key also no response. The led light always black, only become red when I connect it to my pc.
What should I so now and what's my phone's status? I searched something about 9008 mode and edl but I don't know how to check whether my phone is really turn into that status, my pc cannot dect my phone.
Have the same problem, only with the 5 iii instead. Still looking for a fix.
Try to switch the phone off; then just plug it into your PC without holding the Vol- key. It has happenned a couple of times with me that the phone does not want to boot up, with attempts to get it into FLASH mode by holding the key down throwing more confusion into the mix.
I think there is a low battery protection. Make sure the phone is charged up. Keeps the device from death during a flash.
Red led mean a very low battery. Keep it plugged (not to PC but to power adapter) for 2-3 hours and then try again a force reset.
Never, never try flash or other stuff under 50% battery
Also force restart is keep pressed vol+ and power button (or vol- and power button) till you fell a vibration.
Try this after a good charge

It might require experimenting with service modes and different chargers. I had an early Xperia 1 III that bootlooped while charging after setting up the fingerprint reader. It seems that charging is disabled during booting. It has to finish or enter a service/fault mode.
my phone is having this after doing fastboot --slot=b reboot recovery (which actually I had to do fastboot --set-slot=b and then fastboot reboot recovery). the notification light blinks red. have tried vol up + power, vol down + power, and vol up + down + power for like 30 seconds and nothing

I feel sorry for you brother...such a nice device...OK let's talk what happened, the state now your device is in is called hardbrick and it had a corrupted bootloader or no boot loader, but your device is still alive, in your PC in device manager it lists as Qs USB mode with some number after it like qsusb9008...now this device can only be brought to life with the help of a blankflash file which can flash your boot loader in snapdragon service mode...actually no snapdragon can be hardbricked permanently now you need appropriate blankflash file for your device.. Please don't open the device if some repairmen suggests to do JTAG nothing is necessary all you need is blankflash file which is shared to only Sony testers groups.... Who tests ROMs before release and they hardbrick so they share those files to them.... Please don't loose hope....it takes time but certainly it can be bought back to life... And dont try any flashing utility as there is no functional boot loader on it now and nothing will work...Sony won't provide that for sure and they will say then can only solve by mother board replacement ,don't believe therm your device is perfect it only needs blankflash file as it entered into final safe mode... I ain't regular on XDA if you need any info contact me via my mail [email protected] g ma I'll .com
Have any of you tried this - https://developer.sony.com/develop/open-devices/get-started/flash-tool/download-flash-tool/
ok in my case it was the charging IC
