Thanks for telling ! I had been looking for this information for a long time.
Apparently, my service info says "bootloader unlock allowed: yes", I wonder if it means that I actually unlocked it or that the device would accept me to do it.
I moreover wonder how one can manage to install CM or root its device without using Recovery Mode. I saw on your signature you rooted your device. May I ask how you did that ?

It means your bootloader CAN BE unlocked.
To install a ROM, such as CM, you first unlock your bootloader, then move the ROM zip to your device. After that, you flash the included kernel from the zip with fastboot. Then, you boot into the included recovery from the kernel and flash the whole ROM.

I finally found a solution to my problem : I unlocked the device using flashtool-0.9.11's gui procedure, instead of flashtool's fastboot. It succeeded and I can successfully flash anything I want on the device.
I found your rational approach to my problem useful. It helped me isolate a solution. Thanks !

Press and hold the Power and Volume Down keys for 10 seconds.
The device will reset and restart.

random restarting

So recently my swift 2 plus has started randomly restarting when I'm doing stuff on my phone. I haven't changed any settings or installed any new apps so I'm not quite sure what is causing this. Has anyone else experienced the same problem and has anyone got a fix for it?
This could be caused after several OTAs. I'd try getting into Cyanogen's Recovery mode (while the phone is off, press and hold Vol- button, then hit the power button a few seconds until it vibrates without stopping holding the Vol- button, and once the Cyanogen Recovery pops-up, stop holding it), and from there do a Factory reset.
If that doesn't solve the issue, I'd contact whichever store sold you the phone to get a replacement ... (Or, opening the bootloader and flashing the latest stock rom image via fastboot, but, I'd not unlock the bootloader at this point if the phone is broken for any reason)

Redmi 3 Pro Dead Brick

Hi,
I got brand new Redmi 3 Pro (3/32 GB) which is great device. I wanted to install MIUI 8 on it so I applied for unlock which passed ok.
Then I download a MIUI 8 ROM (cannot remember which one now) and pasted into my device as a .zip file. I went to 'Update' app and I choosed the file. My phone rebooted and it went into some mode (please note that my knowledge of flashing is very poor) where it was installing the package. It did not show any veryfication screen at any point. The phone was in that state for about an hour when I decided to reboot it - I held the power button for few seconds and my phone switched off. Now I am unable to switch it on.
I tried to boot it in Download Mode but nothing works. I was pressing the power button for long time - nothing happened.
I tried to hold Volume Down + Power Button - nothing
Volume Up + Power Button - nothing
Volume UP + Volume Down + Power Button - nothing
Volume UP + Volume Down - nothing
The sceen remains blank and no light is turining on - not even the light when I charge it.
I was using two different comupters with Windows 8 and Windows 7 but no luck. I installed MiFlash and MiSuite. When I connect the phone to the Windows 8 machine it gives me the sound of connected device and MiFlash shows a device that is connected but it cannot communicate with it. It stucks on "Sending Hello Packet" - the phone does not respond back.
I was following many tutorials but none of them solved my problem.
and many other threads but nothing helped me.
Please give me advice what should I do.
You have to work with edl mode and port v7.1.2.0 rom.

t870 S7 unlocked bootloader stuck in loop

sm-t870 unlocked/rooted stuck in bootloop
cannot enter recovery or download mode, or even seem to shut the tablet completely off.
any combination of buttons turns the tablet on with the message "bootloader is unlocked press power key to continue"
so holding power+volUP, must be let go to press power which seems to interrupt the button combination
power+volDOWN seems to shut the tablet off for 5 seconds but it automatically turns back on.
having plugged into laptop seems to make no difference.
help!
Hi man, have you fixed this issue? I'm having the exact same problems as yours. I updated my Magisk it just went bootloop.
Thanks!
Plug into PC then Power+Volume Up got me into recovery mode

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
