[Android Q&A, Help & Troubleshooting] rafael_mfr:
My ASUS PadFone 2 was with CWR and latest fw (10.4.12.14) Linderburg version which is Deodexed, Zipaligned and Rooted, it was running smooth and perfectly, however phone started to freeze sometimes for a few seconds, so I decided to do a reboot. After the reboot, phone hangs at the white ASUS logo during boot and stayed there for 15-20 minutes, until I decided to do another reboot by holding the power button for a few seconds. Finally tried to enter fastboot mode (PWR + Vol UP) and phone got black screen permanently.

Recently I got my SECOND ASUS Padfone 2 with the same issue. This one was on stock (unrooted) and latest firmware.

Finally the phone simple doesn't turn on, screen stays off, no recovery, no boot, nothing.. the only thing it happens is that device manager from windows 7 (64 bits) just recognizes it as QHSUSB_DLOAD device, as you can see below:

Googling about this error on the internet, I found that some of HTC devices already had this error: http://xdaforums.com/tags.php?tag=qhsusb_dload

ASUS already know about this error that phone cannot boot propertly, it's a know issue, and it has an official note about it on their (taiwan) website: http://www.asus.com/tw/News/IOkzw7fDcerZuFoJ

However my phone was bought on the first months of sales 14/Dec/2012 in Switzerland during a trip and currently I live in Brazil (Recife City), so I contacted ASUS Brazilian Support Center and they claim that as the phone was bought in Switzerland I should contact the support from there, but I don't have anyone who can support me there and also I don't speak french. They only give support to devices bought in Brazil from a official reseller.

I thought all of ASUS devices has Global Warranty for a periodo of 1 year. I was wrong!

Many sites of Android fans said something about this issue:

"Thankfully, ASUS is well aware of this issue and they have released a statement confirming it. The issue seems to be with the firmware and the eMMC on the affected devices but ASUS will be replacing the affected devices.

"ASUS confirmed this problem and released a confirmation, promising to replace the affected devices.

It was not only my device who got this problem, many people had it and related their problema on MoDaCo and PadfoneCub foruns.

For now, I've an almost dead device and don't have who can help me.

Do you have any ideas? All advices will be much appreciated.

THANKS IN ADVANCE!
