Bootloader doesn't exist on Nand........ - Android Q&A, Help & Troubleshooting

Hallo to entire forum,
I have a phone called Y9190 that suddenly turned off and will not turn back on. I tried to flash it with flashtool, but the program sends me this error: "Boot Loader does not exist on NAND / eMMC flash! Please download bootloader first."
At this point, I do not know how to go forward.
The flashtool drivers are installed correctly and the rom is the right one.
Any idea to help me?
Thanks in advance

Any suggestion is welcome.....

Same problem
I googled it and many of the answers are opening your phone and unlocking your bootloader, but how?
The phone is dead and won't open...
I've got the same message "Bootloader doesn't exist on nand flash. please download bootloader first..."
UP FOR THIS!!

They most likely removed the bootloader. This is not uncommon with some China based knock off devices.

[Q] [failed to boot 2] How i do ?

Hello everybody !
I wanted to install a new "ROM" on my device. I installed the "ROM" with "RCW" and everything went well.
But when I turn on the device again, the following message appeared:
"Failed to boot 2"
"starting mode rsd"
What should I do?
I tried to reinstall a "ROM" in "SBF" but the process to stop after a while and says "failed".
I also tried with "fastboot". Everything seems to be fine but the device shows the same message.
Any idea? Have i to unlock the "bootloader" again?
My device is an "AT&T" from "United States" and used in France. The latest version of "android" that I used was the official 2.3.4 updated "in the rules" with Motorola.
I just wanted to install a "ROM" more Sympathic. Until now I had just root the device and unlock the bootloader.
Thanks for all !
P.S: I searched around and tried many things. So I'm sorry if there is a post that I have not seen about it.

If the boot screen shows unlock on the top of the screen than u don't have to unlock the bootloader again.
You should check if you get the "unlocked" message on the top left side of your screen to ensure it is unlocked or not.
If it doesn't show anything, you should try to unlock the bootloader again.
Just be careful to not flash any rom through SBF before make sure you are not downgrading your Kernel version, or you will hardbrick your phone.
The Pudding (http://forum.xda-developers.com/showthread.php?t=1136261) thread and the Brick thread (http://forum.xda-developers.com/showthread.php?t=1160408) should give your more insights about this.
I'm searching for some screens and a thread explaining how to unlock the bootloader in the safest way. As soon as I find I'll edit my post.
Thank you for the answer.
I'm also looking on my side. The first is that the announcement to another.
Thanks again ;-)

FAILED (remote: Command not allowed) flashing recovery or boot img

Hi,
I made a different thread to find a solution about this error I got when I try to flash the Androkernel boot.im and TWRP recovery on my UNLOCKED BOOTLOADER Z4 712 wifi european tablet.
I updated with the Sony PC Companion tool, I DID NOT turn ofn the MySony Security (that was THE problem that caused this error last time), and bootloader is still unlocked (checked with Sony Mobile Flasher).
The service mode say "root:unknow", in previous tablets/room it should say "bootloader locked or unlocked", but I'm not sure.
That's what I got when I tri to flash boot.img:
C:\>fastboot flash boot boot.img
sending 'boot' (32584 KB)...
OKAY [ 1.633s]
writing 'boot'...
FAILED (remote: Command not allowed)
finished. total time: 2.150s

First of all it's not polite to create new thread in android development part. Here should be only roms, fixes, patches recoveries. Not q&a threads.
As to your problem, are you sure that you've unlocked bootloader? In service menu you should see
"Rooting status:
Boot loader unlocked: Yes"
if you doesn't see it, it means you haven't unlocked it or unlocking is not allowed on your device.

Hi,
I think the problem is here if you enable myXperia before or after unlocking the bootloader ( can be @AndroPlus can explain better the problem ?)
Verify that your USB drivers for fastboot and adb are correcctly installed (install the USB drivers provided with Flashtool)
I hope you can root your tablet again :good:
I'm very sorry if I opened the thread here, feel free to close or move it, but I found it related the modding and , actually, in installing the androplus kernel.
As I said I did not turn on the sony security nor befor nor after, root status is "unknown", Flas Tool say is't unlocked, I already flashed the androkernel before and the problem was the MySony security, but now I know I don't have to turn it on.
Drivers are Ok, I flashed the new rom with Flash tool and then with Sony Companion.
Anyhow, if I'm bothering with this thread pleas close it, al try again and again
I think it's okey moderators will move the thread over.
Did you unlock your tablet by flashtool or follow official Sony instructions?
Do you have myxperia app installed?
Have you got factory reset after unlocking?

Do you have myxperia app installed? yes, but it's not enabled! Actually it's not an app, but an option in "security" menu.
Have you got factory reset after unlocking?

First of all, I don't really understand how he was able to update something via pc companion with unlocked bootloader?
No ota update, nor update via pc companion is available after unlocking.
DHGE will we have the same? I mean when android MM will be released, we flash it and will it be with myxperia? And if we launch it by accident we break our tablet, right? In this case, how to remove it, factory reset?

I read about a guy thoblem because after updating with Companion bootloader was relocked, he unlocked again and so.
Anyhow,I just NOT UPDATED, but RESTORE/REFRESH the firmware flashed with Flashbout a bad flash with Flashtool. Immediately after the flash with compsnion,even without turning on the phone, I try and I got the same FAILED (remote: Command not allowed)
:crying:
I even relocked and reunlocked bootloader with Flashtool (didn't even know it's possible to relocked...).Thi lost :-/
UPDATE: I found that myxperia was administrator even if I didn't turn it on, so I remove from administrators, but....same problem
Maybe it's better to try to unlock bootloader again following official Sony instructions, not flashtool? WITH flashtool unlocking, you haven't got a factory reset, that's the reason of all your problems IMHO.
After unlocking my xperia must disappear.

SONY thinks MyXperia is a useful feature security wise and I agree. It is just not for me since it prevents my tampering with the device.
I am sure it will be in MM.
You have to launch it explicitly on setup! SONY warns in the bootloader instructions to activate it after unlocking.
Once activated after unlocking the tablet is bricked. End of discussion, beaten to death in the xperia fora....
If a factory reset could revive the devices this would be no security feature but rather an annoyance for thieves.

I completely agree with what @DHGE said this is a no sense if a thief can reset the tablet with a factory reset once MyXperia has been activated. MyXepria operates at a low level, also be able to deactivate it easily is not possible.
:crying:
Oh my God.I haven't known it. http://fxpblog.co/2015/07/03/dont-destroy-your-unlocked-device.html poor people. Indeed, with unlocked bootloader and enabled myxperia, people get tea-tray instead of working device. And it's unrecoverable.
If nevertheless icon of my xperia will appear in a menu of new MM. Can I delete it with some kind of system-app-uninstaller ?
Edit 1. This damned app was in my system, so I used "Uninstall" app and remove my xperia, wiped dalvik and cash.
I strongly recommend it everybody to keep your device safe and don't worry incidental pressing.Better delete it!!!
I activated myxperia with unlockebootloader and I have no problem, can't be able to unactivate it, when I reflash the ro if activate it or not and I can remove administrator priviledge in security section.
If I clickif I want to turn it on and sony says that "if turned on"repair the firmware but will be "unusable" till you imput your google account saved for the my'm UNLOCKED I try turning on myxperia a few days ago to an disable it later (no ways, my xperia has only a blank page without settings), then I reflashed 2 times and both time it asked me if I to turn on the myxperia.I even try with flashtools to chek the bootloader, relock and reunlock and everything wly problem is flashing things via fastboot!

HELP please... HardBrick RN3SD

i don't know what to do... i think i read every tutorial for unbrick my phone but nothing works...
my situation:
-i unlocked my fone by unnoficial method, instaled twrp and everything was ok.
i decided to instal sMIUI, but nowhere i read that is necesary to delete emmc file... so i bricked my phone.
bootloader got relocked, i can't turn on my phone, mi logo appears during 1 sec > screen off > again mi logo during 0.001s > screen off
when i plug in my phone into my pc, i have black screen and red led, but it's not adb mode.
i can't enter adb, my pc (windows 10 x64), i use command "adb devices" and list is empty
i can't edl
i can enter in fastboot mode.
i can't flash nothing, "failed: device is locked"
anyone can help me?
if i unlock officialy my bootloader, can i flash again stable rom or something? i just had my phone during 2 weeks.
can i do anything?
thanks.
one more thing: i had guaranty, so, if i unlock my bootloader officialy, i lose it?
i don't want to try testpoint method, because of guaranty.
Well, welcome to the party.
Irrespective of how much u search, cry for help or open millions of threads like this instead of doing a little search, there is no solution except test point method. Now don't ask how to do it. Search and read a little u will get the necessary info.

Don't worry bro u will certainly do what is required. I was the first who reported a bricked device while unlocking bootloader by unofficial method. After extensive search and trying different methods I came to this conclusion.
