[G Tablet Q&A, Help & Troubleshooting] FarSight87:
Soft-Brick looking Hard Brick...Hmmm

Hi,

Does anybody know if the OP got this problem sorted? I am having the exact same problem. Hanging on Viewsonic Birds logo with other exact symptoms.

Current Situation:

1. Power/Vol buttons work and tablet visibly boots up to Viewsonic Birds Logo (where it hangs).

2. I can access APX mode and can NVFlash without problems.

3. If i hold vol + to access cwm recovery after nvflashing part9.img with cwm, it hangs on VS logo with "RECOVERY KEY DETECTED" and "BOOTING RECOVERY KERNEL IMAGE" and nothing happens.

History:

Before this happened my setup was: BL1.2 with Gtabcomb ROM partitioned 2048. For one reason or another my touch screen became unresponsive after a couple weeks, I entered cwm and did a factory reset (of gtabcomb rom), to no avail.

Stupidly, i nvflashed directly back to BL1.1 bekits original image following this. Im tipping that may have brought on my next problems as now i am stuck.

I have tried the FORMAT tool/CODE DETOX here several times to no avail. Ive followed the Format with a NVFLASH into each of the following in turn:

BL1.1 3588 without cwm

BL1.1 3588 WITH cwm

BL1.2 4349 without cwm

BL1.2 4349 WITH cwm

(as listed in table here)

Results are the same

1. Tablet will not go past birds logo on normal startup

2. Tablet will not boot into CWM recovery with Vol+ held at startup (on roms with cwm)

3. Tablet can still enter APX mode as normal.

NOTE: Most posts i read about NVFlashing say that the tablet will reboot automatically, however mine does not. Not sure why, Im using Ubuntu and when i try "lsusb" in terminal i get the "ID 0955:7820 NVidia Corp. " as your supposed to. This could be completely irrelevant though.

Any ideas?

My last NVFlash looked like this:

EDIT:

I have also followed this guide up to step 04)EXECUTION e)3. Which says that I should now be in CWM recovery to repartition to 2048, 0. But all i see is a Black Screen containing:

LINE1: "Entering NVFlash recovery mode / Nv3p Server"

LINE2: "Recovery key detected"

LINE3: "Booting Recovery Kernel Image"

All on the same screen and just hanging there. Cannot Proceed. :-/
