I flashed a faulty recovery using mobileuncles and there was no signs of life other than a red led liggt, and holding power + volume up works just fine and it went into flashmode.

I have the same issue.
I organized xperia light rom for our xperia c, I flashed it from custom recovery. Phone is completely dead now.
There is a just red light, phone does not go into download or fastboot mode. Pc Companion, Sony Update Center, Wmshua Flashtool do not recognize the phone.
Any suggestion with that?
I don't have warranty, my last option is to pay money for technical service.

this worked for me but instead of POWER+VOL UP i used POWER+VOL DOWN

thanks
thank, i like this forum

worth to try... (hope it won't happen to me :laugh: )

I have experienced this too, however, instead of using the Sony Update Service, I used the Sony PC Companion. At first it was not working, so I did a hard reset on the phone (press the button at the back). I held the power+up button while inserting the cable, and finally it was detected by Sony. It will reset your device to factory settings though.

If you flash a different device's rom, it happens. If you replace your motherboard, it will work again.

It worked for my Xperia M (rooted on JB 4.3) with a locked bootloader which was STUCK on bootloop screen and when I did the whole thing with holding the power and volume up button (after I let the battery die after so many bootloops it did), FINALLY I was able to take it to flashmode, while I had selected from Sony PC Companion to repair my phone, and after 3-4 tries, I DID IT!!! Thank you so much for this thread ( I DEFINITELY pressed the "thanks" button), it really SAVED ME time and money (because I was planning to send it to Sony to fix it and you ALL know how bastards Sony is)!!!! And to all those of you who are DESPERATE to fix their phone (I hope you read this thread), DON'T PANIC, and DON'T GIVE UP!!! It took me 2 days of searching the web, and FINALLY I MADE IT!!! There are ALWAYS solutions to these kinds of problems!!!!

Xperia Z5 not booting up/red blinking light after update = Bricked?

Hi gang,
My Xperia Z5 (E6603) would not boot up after the latest update. I'm guessing it must've died during the update.
I tried:
Reset (Pwr + Vol+/-) and OFF button in sim card tray. All reset attempt was done several times with and without the simcard tray.
I noticed the phone did not vibrate when I tried Pwr + vol+ or with the OFF button by itself. It only vibrate when the OFF and Pwr button were held down simultaneously.
To rule out it was battery, I let it charged for almost 2 days now without any success. I still get the slow blinking red light and no solid red or orange or green light indicating the device is fully charged. I also check the integrity of the battery at the stored and it is at 4.0 V, so I believe the battery is not the problem.
Unplugging battery method: Tried unplugging the battery and connect to the computer then plugged it back in with no luck.
Flashtool was not recognized after holding Vol- and connect to the computer.
I also tried different charger and usb
i read from many forum that the battery needs to die in order to reset the kernel. Should I just let the battery discharged? Or are there others ways that are more efficient?
I'm not sure what to do at this point. Any suggestion will be greatly appreciated.
Thank you!

Go to phone repair outlets in your city, not in Sony Service Center. usually they can fix hardware problem. I dont know what software are used. I only know with Jtag can repair bootloader via test point.

Does the bootloader need to be unlocked on the phone previously for the JTAG method to work?

not sure. locked or unlocked should work, because the files inject directly to emmc
by the way, have you try to change another battery?

ave you tried to boot the phone into download mode?
Have you tried the actual Sony Tool and the Recovery-Process?
With that i unbricked my Z5 from that symptons i think 2 or 3 times already after the flash went somehow wrong because it stopped midway.

Another thing - on my Laptop i can't access fastboot mode because it restarts everytime (showing the blue led and then it reboots), therefore i have to attach the Z5 to the Dockingstation.
But it seems like it is completeley dead right?
just to be sure - press and hold vol up and then connect your usb-cable. If the LED stays blue - gg
Then you just have to install the fastboot driver in Test-Mode (reboot to f8 and deactivate the Enforced Driver Signature) and then you may be able to atleast flash or better first boot the phone with a new kernel. If the boot works and then crashes you have your first step to unbrick the phone.
fastboot boot "kernel-image"
Altough i don't have any idea which Kernel you should choose

Bricked S8+ SM-G955F while rooting!?

Hello!
I tried flashing another ROM to my S8+. The ROM was downloaded from SAMMOBILE and I followed the instructions step by step. While flashing with Odin ( Odin was downloaded from the link they provide on their site ), 5 seconds after I pressed START the phone just powered off after I pressed the bixby button by mistake. Now, the phone won't even power on and the led isn't turning on when I charge the phone! What can I do? Worked so hard for this phone!!

Was it fully charged when it when off?, maybe let it discharge overnight
Try to charge it with a different cable/charger
Make sure that none of the buttons are stuck, press them one by one to make sure they work properly
Press power on , plug it into your pc and see if the device is recognized
do all of the above with the SIM and memory card out.....
What setting did you have in odin....
What it was flashing when you pressed the bixby button?

Hi again and thank you so much for all the help!
I had around 70% battery life so there was no chance it went from 70 to 0 in 5 mins.
It can not discharge because it's turned off and I can't make it power back on
I was flashing the AP file and 3 seconds after I hit start in odin the phone just powered off. All the buttons are working properly and there is no SIM/memory card in it.
If I press the power button nothing happens...same when I connect it to my PC....nothing
The phone is dead and so am I ))

Hi
Just the AP file what about the other 3 BL , CP and CSC? and what Odin setting you had?
My best guess is that the hardware is in an undetermined state ..not necessarily bricked but it may be
Keep pressing the buttons , try to get into download you may get lucky and catch the hardware "awake" and let you get into download mode...if so flash the firmware again...all 4 files

If you are in the same base , Nougat to Nougat, flashing just one of them should not be too bad..but when changing base Nougat to Oreo...that is not a very good idea, is complete different firmware and they may not be 100% compatible
lets cross fingers and hope for the best

Hey, did you manage to start your device again normally?
I'm having the exact same issue and there doesn't seem to be any solution online.

Hello it's me (maicanvlad7) but from a guest account. It didn't start so I was forced to use the warranty. Depending on your location you might or might not be able to use the warranty. There is no software solution for this problem, none that I know of at least. Best of luck man!

OnePlus 8T Dead (Solved)

When I used the Fastboot Enhance tool to flash the payload.bin file, after the flash process finished I try to reboot but unfortunately it was dead.
No Fastboot, no EDL, no recovery, 3 buttons not working, power with up/down not working, when i connect to PC no sound that the pc recognize the phone "OP 8T", when I plug it into charger no info showing, Just black screen.
So it's working now, I'll explain everything here so it might help.
My device is OnePlus 8T DDR5 version
first, I understand what happened to me, I think the tool didn't recognize ram type automatically so it was flash DDR4 on a DDR5 device, so it made a hard brick
at this point, the idea is to connect 2 test points, and you can force your phone to enter to EDL mode, and we can do it in two ways:
1. Rootk1t giude, thax bro Rootk1t
- Removing the back panel by heating it.
- Unplugging battery
- Then use the EDL points on the motherboard to force the device to boot EDL.
- The device immediately will be recognised with just one tap on "enum" now.
- Plugging the battery again and attaching the back panel and rebooting
2. By using deep EDL cable, but not any edl cable, it must be a moded cable so it can be worked with the new security ...... this link will explain
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! - GSM-Forum
Hydra Tool Gift Xiaomi, Huawei, Redmi Qualcomm EDL Mode New V2 Cable!! Hydra Tool New Type-C EDL cable Schematic With this cable you can reboot your
forum.gsmhosting.com
- So i use Hydra EDL Cble V2 , you can buy it from aliexpress
- Be ready and open your MSM tool
- Press the cable button before connecting
- Connect the cable to your phone when you still pressing the button
- Then connect the USB to your PC
- It will automatically put your phone in EDL mode
- Now your phone will show in the MSM tool screen so you can revive it.
Thanks to everyone who tried to help.
Special thanks to Rootk1t , semdoc

Seem like you flashed the wrong xml for the ram type. There is one for ddr4 and ddr5. If EDL is not working I'm afraid according to several post it's an unrecoverable brick...sorry mate!!!
However keep searching for a solution, you never know maybe a new method of recovery from this disaster may exist. I'll keep searching and if I find anything I'll post it here!
Also have you tried the 3 buttons connected from charger and disconnected? Usually for some reason my phone won't respond with the 3 buttons when connected to usb sometimes.
Also have you used the msm tool before?

Just one more thing, when you connect the phone to pc check your device manager to see if the PC reads the phone. If it does than its just a driver issue and reinstalling the qualcom driver for msm maybe needed.

I've found that sometimes I have to reinstall the Qualcomm drivers for EDL. So check that when you connect the phone to the PC in EDL mode there isn't an entry in Device Manager under Ports (COM & LPT)

I can't know which mode the phone is stuck on, because I have only a black screen, even the Power button with volume up / down not working,
do you think if I keep it for a couple of days the battery will drain and I can use MSM tool with press 2 volume buttons, it's the last thing i think about

I would open it up and remove the battery instead of waiting for days but that's also an option. It's not that hard to open, I opened mines to replace the usb port. I just held the back of the bottom corners of the phone over the stove until it was hot enough to soften the glue and used an old credit card and my thumb nail to open it. It maybe unrecoverable anyway so its worth a try.

I've had a totally black screen at times in Qualcomm Crashdump Mode. To get out of it you can use Power+Vol up and then, when the phone buzzes, use the key combination for bootloader or MSM.

I tried a lot to press Volume Up + Power & Volume Down + Power & the 3 buttons, but with no response.
I can't feel any buzz, even I tried it when the phone connected to the PC, no sound come from PC prove that the phone is connected

Please keep us updated with any current queries or resolution as I'm very interested in the outcome.

Hello!
If waiting for battery to discharge will not help you, i suggest of:
- Removing the back panel by heating it.
- Unplugging battery
- Then using the EDL points on the motherboard to force the device to boot EDL.
-The device immediately will be recognised by just one tap on "enum" now.
- Plugging the battery again and attaching back panel and rebooting.

thanks my friend for your suggestion, yes I was thinking about this solution, but I keep it to be the last one, I think I will try this method at the weekend as I'm busy with work these days.
I'll tell you after I try this solution.
Thanks for your cooperation

Dead boot

Hello, please help. I have a big problem.
I just flashed custom ROM and the installation was successful. When I restarted the phone, it stopped at the "Samsung Galaxy" logo and did not complete and then restarted automatically in this case. I tried to enter twrp, but to no avail. I also tried Entering the download mode, but also it does not work
I hope that someone will help me, and is this how the phone was damaged, or is there hope to recover it?

Try holding power and volume down for over 20 seconds, after the phone reboot keep holding those keys and hope you get into download mode

Does Odin recognise the phone?

Unfortunately not, I even tried to enter it into download mode by pressing the volume up and down buttons and then connecting the USB, and it did not work, so I think it may need a board

Can you disassemble the phone and remove the battery and reconnect it again and try to put it into download mode?

Honestly, no, I haven't tried jaw before But I waited until the battery ran out and tried again to insert the download, but it didn't work either,,, I have a question I first formatted and then installed the ROM, then it succeeded, but after the word “installation was successful” there were words in red “failed mount system root” Then I flashed the rest of the ROM files, then I thought it was over, so I restarted, but it stopped at the "samsung galay - secured by Knox" logo. It does not continue and then restarts itself in this case and does not stop until the battery runs out and stops then I tried to enter the recovery but to no avail and also the same thing with the download mode,, summarizing all this does the phone need a motherboard, or that the matter can be solved?

It can be solved. It doesn't need a motherboard.
Try Chimera tool. It can fix dead boot. You may need to short test point of your phone so that the software recognises your phone.
