- How to use fastboot

Please read carefully and thoroughly all the steps before you start...if something is not clear then feel free to ask...its easy to softbrick your tab and not as easy to unbrick it...

You will need your CPUID - this cannot be said enough!!! Please do not attempt any flashing until you have a copy of it stored safely!!!

Bear in mind - installing custom roms and a recovery IS NOT DONE the same way as on your phone or other android device!!!

You must install the "skrilax_cz unlocked v8 bootloader" to install a custom rom/recovery

There is alot that can go wrong and you will need to follow the directions to the letter.

If you are stuck with the acer logo on boot or faced with a dead android or a recovery verified failed, when booting to recovery

then you have not followed the correct procedure and at the very best will need to do this all over again.

Before you go any further and while you can still boot into your tab - please retrieve your CPUID - see my guide here

Summary of Steps to flashing the skrilax_cz unlocked bootloader and custom recovery using nvFlash

Step 1. Install the Acer Drivers here and the USB drivers from the Android SDK here

Step 2. Retrieve your CPUID

then head to blackthund3rs site to generate your sbk

Step 3. If you are running factory stock - you will need to rename or delete "the boot.p file" in /system to prevent your custom recovery being overwritten

- Use blackthund3rs ICSRoot here which will rename "the boot.p file" for you

- Have your Custom Rom downloaded and copied to your External SD Card ready to install immediatelyafter flashing skrilax's patched bootloader

- You are now ready to proceed with the "installation" you will also be asked to choose a Custom Recovery (CWM, TWRP,or Public)

Step 4. There are a couple of ways of doing this, manually or with one of the Auto Tools

- civato's manual nvFlash download and Guide and a walkthrough here

- Download gersma's afterOTA Tool if you have OTA'ed to ICS

- Download blackthund3rs apxFlash Tool and a walkthrough here

Step 5.To Manually Enter APX Mode

Once the flash is complete, boot directly to Recovery, Do a Wipe and Format and install your Rom!!

I have the unlocked bootloader: how do I update or change my recovery?

Only a few custom recovery's are compatable with ICS Custom roms, I've attached these to this post and they need to flashed via fastboot

Via Recovery:

There are some flashable zips around so copy the zip to your external sd or flash drive

boot to recovery and choose:

Install from zip option

Navigate to the zip and flash!!

Via fastboot see Post 3 for using fastboot

Use Acer Recovery Installer from the playstore

Please note again this is only possible with the unlocked bootloader

I'm on a stock rom, How do I root, I don't want a custom rom or recovery?

If you're happy with Acers Stock Rom?? and just want root, there are a couple of options:

blackthund3rs icsRoot.zip in Step 3 above - extract and run the .exe...Done

Original thread [ROOT] Stock ICS Leak One-Click Root Tool

For those wanting to root manually ZeroNull's method Full root for A50x ICS 4.0.3[LEAK]. Simple method.
