stuck in apx, no ADB or Fastboot

[aliaksei]

hi,
before updating to 4.3 via OTA i was rooted via chinese method and had problems with my wifi, i decided to wipe my note using fastboot -w, to see if it would fix the wifi issue, afterwards it booted up and i installed the 4.3 OTA, i think it installed but my device went into a bootloop and i can not get ADB or Fastboot to recognise it (I know the drivers work, they recognise my LG G2), the only device showing up in device manager is APX. I did some googling and found that its Nvidia low level recovery system. Is there any way to get my TN7 out of APX or do I wait until Nvidia release the relevant blobs? (Am I right in saying that Nvflash doesnt support Tegra 4 yet?) Can you guys think of any solutions? I am happy to try experimental, pre-alpha stuff!

Thanks in advance,
Aliaksei

Sorry to say that no one has yet got NvFlash working with Tegra 4 SoC, bar in-house developers and wholesalers.

If you can't get the device into fastboot then your only alternative is to return the tablet on warranty since you are not getting a proper bootloader which is a sign of an early released unlocked tablet where legally there was no hindrance to tinkering. To get fastboot try;

Starting up the device with the POWER-BUTTON + TOP VOLUME-BUTTON held down at same time. The device will boot and as soon as you see the logo, then release only the POWER-BUTTON so that the device doesn't do a unwanted restart on you. What you should be trying to archive with this is get to a menu based bootloader if you have one. There, you should be able to toogle on fastboot and recover the device.

I hope that helps.

If I return it on warranty, will they be able to see that it was rooted, invalidating my warranty?
