[A51x] Key shortcuts (recovery, bootloader, factory reset)

---

Don't recall seeing this yet on the forum, but here's a list of "keyboard shortcuts" to boot your device into bootloader, factory reset it or boot the recovery.

Recovery:
WARNING: if you have stock recovery and an update.zip in your external sd it will start to flash immediately
Volume- (two dots) and Poweron

Bootloader:
WARNING: this is very similar to factory reset, which will start immediately
Volume- (two dots) and Poweron and then toggle the rotation switch on and off a few times

Factory Reset:
WARNING: reset will start immediately
Volume+ (one dot) and Poweron and then toggle the rotation switch on and off a few times

APX Mode (for NVFlash):
WARNING: use APX mode only when you know what you are doing!
Hold Volume- (one dot) and Volume+ (one dot) and press reset button & release volume keys
Screen will stay black and power led will not light up. The only way to check APX mode is enabled is to plug the tablet to the PC and see if the APX device is there.

Nika.

Recovery is using [volume-] + power ;)

oh silly me, I keep mixing them up. Modified them now... glad I added the warnings

Indeed, they are still wrong

vol-/power = recovery
vol-/power/rotation lock toggle = fastboot
vol+/power/toggle rotation = hard reset (that one was right )

Yeah, just figured that out myself. Sorry. Changed it now

You can add the APX mode :

• hold vol+ & vol-
• press [reset] once
• release volume keys

Screen will stay black and power led will not lit. The only way to check APX mode is enabled is to plug the tablet to the PC and see if the APX device is there.

Good one. Added it. Alternatively you can also restore an invalid boot image, and brick your device, or something like that to get into apx automatically

That would be too easy. I have done this in a more
interesting way after corrupting /data by the CM5 wipe and trying to repartition internal mem :

Pls, excuse me for any inconvenience, I'm not much of a poster here, so the forum didn't allow me to post an external link and the attachment got automatically resized. Going to take super-regulatory measures and override the rules

I soft-bricked the phone with the CWM Recovery 5.0 Wipe, as I mentioned before, after only 3 months of using a rooted device, while trying to get a custom ROM installed to get usb camera driver working, found out that the /data partition has been corrupted by the old CWM ver, read the partition table size somewhere on the net for A510 and tried to repartition the SD to 12GB as it should be, but noticed the 32GB SD/MMC size mark in the output of the parted tool right after I entered the 12800 as the size. Was a little bit shocked, tried to apply some other's tablet partition sizes in the end, and this eventually bricked the device to black screen

And yeah, I did pay for the 16GB ver, the receipt said it's 16GB, the box has 32GB print label, the device has been partitioned as 16GB, I took it apart and read the memory label it was 32GB, if I am not mistaken, I assembled it with no issues and then I was able to partition it AS 32GB, as you can see on the screenshot. All I wanted was my device back to life, but out of curiosity couldn't stand trying to get extra 16GB for free. Curiosity killed the cat

The device now can get into both: APX with both volume down and reset AND into a 1-2 sec boot up with no vibe or screen light up after a short single power button press which is enough to get detected by a PC and power off immediately!

All my attempts to bring it back to life have failed, there is simply no custom software for it yet! NVFLASH was not able to do anything with it either. Acer support told me they do not have any access to give me a temporary login and password for the Acer Download Tool which would save the world for that day, and the device has my corp data within, so I can't handle it to any repair shop and it's just resting on the shelf as a bunch of antiques

Acer, I think this is a bit unfair, so I am putting an EXTRA effort into this...

Thanks in advance to whomever will look into the issues with internal memory and perhaps bring a second life to my and such other devices on the planet!
