is there any hopes of me getting my tablet to turn on again?

nope they purposefully bricked it so at the lowest level it can not turn on short of desoldering the nand and swapping it or some sort of super low level direct write to the nand nothing is going to unbrick a pyro. The chassis and parts is worth something if you swapped a k1 mobo and battery into it...

You did that? the only mobo I can find on eBay is 119 bucks....so not worth it if u ask me.
you know where to get it?

No I just bought a k1... But as they have not elected to make a 2016 tablet as people break them I imagine more will show up. As for everything else a bricked pyro can still be sold for parts to someone who broke a screen on a k1.

I restore the blocked nvidia shield tablet

I recover the disabled Nvidia Shield pad, for this purpose it is necessary to send the motherboard to repair.

There is a person from a forum which wants to send for repair, hope when he writes a response you will be sure that I really repair

Can you please elaborate? I really want to send my ST to you but you're not sharing any information. Can you really recover a bricked tablet from APX state after the kill switch is activated?

It is working!!!

Hello guys!

I have send my motherboard to drims75 from Austria.

It was already stuck in APX mode no change to reactivate.

Today I received my motherboard back and rebuild it to my tablet.

It is working now with android 7 serial number changed (fully official nvidia update no problem) also the battery type is showing now B01.

All I can say now drims75 has really done the job and it is working now.

Always when I ask a question to drims 75 I get very fast answer with pictures.

So please trust him he can repair.

I made photos from my repair process if you need any information please ask!!

I am so happy!

Best regards from Austria to Drims75 and all of you!!!

Regards
Michael

    mine was already bricked and no sign of life except when the light opens when charged thats all and when connected to the computer it just show APX but after few days later it opened and worked like it wasnt bricked i dunno what happened but the only thing i remembered is i prayed so hard to help me fix it xD

    Divine Firmware Update that's an interesting concept... :cyclops:

    IMEI (International Mobile station Equipment Identity) is a unique code each mobile device has, similar to the MAC address of a network card. Changing this is most of the time not possible, being a hardware specific number. That would not help in this case, since nVidia identifies our Shield Tablets by serial number.
    In bootloader mode, there is no concept of "being rooted". You can only be rooted while running an OS (Like Android, Windows, Linux, etc) and means having access to the master Administration account. The bootloader is similar to a computer BIOS. Since Nvidia messed that up with the killswitch, having root or unlocked bootloader has no point.
    The only action is, with the only access remaining, APX mode, to rewrite the nvflash with a valid bootloader and other first boot stuff (similar to rewriting the BIOS on a computer.... You mess that one up, computer is a paperweight). Trick is that only nVidia has the necessary packets to fix the nvflash.
    So, Victor, you did not get your tablet killed by nVidia. Was something else that happened to your tablet. Having access to the bootloader means is still there.
    I hope one day someone will find a way to fix this tablets (hack the APX access, leaked packages from nVidia) because is a big waste of perfect hardware.

    Indeed, 100% accurate!

    Once the killer roms upgrade has been applied, the tablet is dead period. Unless an nvflash package surface this recall is indeed a waste of hardware! Nvflash is fairly common with older nvidia chipset but it's been less and less common with the recent SOC they released. The best is to remove the OTA before your tablet get killed.

    The only question I still have about the recall process is the fact that the made us enter a code inside the recalled tablet, I suspect we unlocked something inside the recalled tablet so that the kill switch can kill the recalled tablet, I would not be surprised that the kill switch would not work on a regular tablet as you would need to enter the code to allow the kill to happen, however I am not yet ready to do a proof of concept test on this theory yet on my hardware :)

    I would find strange that any tablet can be killed by urgent OTA, to me that would be opening a HUGE security hole ..

    I had the same question, but the reason is simple (thanks to Bogdacutu again): the code that we had to enter is proof that we own the recalled tablet. Imagine we could enter someone else serial, from a friend, leaked on forums, etc. and get for free a new tablet, while those would be left hanging. Regarding to the killswitch, you are partially right: from the entered serial at the recall they pair the old and new tablets so when the new tablet connects for the first time to the OTA server, the old one will be sent that broken rom. Thing is, all receive the same 3.1 firmware... all have the urgent OTA option. If the new tablet received the killswitch, would run it in the same way. In the end is a firmware update like any other, only that is broken intentionally :)

    I removed TegraOTA from my new tablet the moment I first powered it on. It did not have time to connect to the OTA server. I did the same on the old tablet as well. Thing is that 27 days have passed since I have both tablets on and according to Bogdacutu OTA check, no killswitch is waiting for my old tablet. So, is exactly as they said: activating the new tablet (more exactly, appearing on Nvidia OTA server) will kill the old one. If is not connecting, it is not killed (at least for now... maybe they will put all the list on death row one day).

    Edit: It crossed my mind now.... If someone would check the new tablet serial also on Bogdacutu page, that might as well mark it active and release the killswitch for the old. Auci !
