[Nexus 7 Q&A, Help & Troubleshooting] Partitionator:
Hi,

I saved the blobs for APX Mode an did the other images like here described: https://www.androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/ because I linke flashing and I´m very interreseted in the Partitions and the Bootloader, and with the APX Blobs I should always be able to revive my device if i brick the Bootloader because the APX mode ist in the Bootrom.

So before I started playing around I´ve made images of all Partitions. Then i relocked my bootloader with fastboot and tryed to reunlock it with flasheung the rigth Partition via nvflash.

The first partition in the Partitiontable hast the id 2. First i tryed to flash back these but i only got this error

D:\Eigene Dateien\Eigene Dokumente\Experimente\Nexus 7\APX>nvflash --resume --download 2 2.img
Nvflash v1.13.87205 started
[resume mode]
failed executing command 15 NvError 0x120002
command failure: partition download failed (bad command)

After that i flashed the kernel with the same command (boot has ID8). After that it booted.

Then i put it back in nvflash mode an thryed partition 3 (PT - Partition Table). That faled with the same error.

Then I tryed Partition 4 (EBT) and after that my Nexus 7 was compleatly dead. I thought no Problem I will just put it in APX Mode again and revice it. But since i flashed EBT there APX doesnt´t work anymore. I press Vol+ and Power as long as I want but nothing, it doesn´t sow up on the PC (another N7 does).

I removed the battery, tryed with or without USB to enter the APX-Mode but nothig.

Another thing that made me wondering was that as the Bootloader was unlocked the Nexus showd the unlocked Symbol after bootstraping it with my blob, and after relocking the Bootloader it showed only Google, without the lock in nvflash mode. But im sure that that wasn´t the flashed bootloader, because reflashed the 4.23 Bootloader after saving the Bolb and as I flashed the bootimg via nvflash i cought it from booting by holding the vol- button it showd bootloader version 4.13 (the version of the modified bootloader that i had to flash for saving the Blob) in fastbootmode.

If it helps you, here is the Partition Table:

Does anyone know why the APX-Mode doesn´t wor anymore and maybe how to fix it?

EDIT: I think its solved: APX-Mode works suddenly again (unplugging USB, holding power and vol+ for 12 seconds, releasing power, but still holding vol+, plug in USB)

EDIT2: I just missed flashing the bootloader and now I have the same Problem again...

EDIT3: OK now it worked again, it think I´m just not able to press two buttons :D

EDIT4: I think now I hard-bricked it. I wrote rubbish on mmcblk0boot0 and now this happens if i try to bootstrap it with wheelie...

Wheelie 0.1 - Preflight for nvflash.
