Acer A500 Starting Fast Boot Usb Download Protocol



A700 won't reboot, says "fastboot USB download protocol" at top of screen even after pressing reset button. Even if I wanted to reset to factory default, which I don't want to do, no menu comes up to allow me to do this. I have tried the power and volume down up process numerous times and it always comes back to this screen. Also it is getting pretty warm in lower right corner even though I can't use it at all. HELP!!!!




acer a500 starting fast boot usb download protocol



It's after that things get weird. When I use the combination of buttons Power, Volume -, Volume + necessary to begin "Booting recovery kernel image" instead I get this: Entering boot menu mode Booting failedBootloader vjB-3fb8d45: Starting Fastboot USB download protocol


My next step was the more difficult reset involving a combination of buttons and toggling the screen lock. I tried this multiple times with and without a microSD image of my A210's current OS. And once again I was back to: Booting failedBootloader vjB-3fb8d45: Starting Fastboot USB download protocol Knowing Android rather well, I fully believed my Iconia could not be truly lost. But I'm now thinking it may be time to hand it over to an electronics recylcer. I realize an Android 4.1.1 tablet is well outdated. But I'm consumed by this challenge. One last clue I can offer is that it went to sleep set on a seemingly harmless web page with a microSD inside. I had been downloading DIY jpegs to the microSD. When I returned to resume about an hour later, the Iconia was fully unresponsive until I realized I had to hold the power button for a full five seconds to get it to silently power off.


The key seems to be "Entering boot menu mode." It's as if the unit wants to find the recovery kernel image, but fails as it immediately follows with the words: "Booting failed." Then immediately appear the words "Bootloader vjB-3fb8d45: Starting Fastboot USB download protocol." The tablet then freezes at the ACER logo screen with those words in the upper left corner, and would remain so all day if not powered down. Since booting failed, there's no capability to scroll with the volume buttons let alone choose any funtion with the power key.


A210 Epilogue: "It's Dead, Jim."After taking ACE Iron-Fly's advice to check XDA Developers, the only input received was similar to ACE Billsey's original suggestion. So as a last last resort I asked if a local phone repair shop by wildest chance had a tool to assess "Starting Fastboot USB download protocol."No was the owner's expected answer. "It's some type of software problem," he said, adding an operating system reinstall and perhaps more was needed. Since only the factory could achieve that given the booting circumstances, the owner ended with the obvious: better to buy a new unit.


The tablet then freezes at the ACER logo screen with the above alert in the upper left corner, and would remain so indefinitely if not powered down. There is no capability to scroll via volume buttons, choose a function via power key, or I'm guessing unlock the bootloader. I think the failure is more than a corrupted boot drive. "Entering boot menu mode" and "Starting Fastboot USB download protocol" suggest a corrupted boot BIOS, as the tablet tries to boot an image from a USB connected diagnostic device. Probably something only the factory has access to and likely tossed for this old of a model.


I downloaded about 4 different versions 2 of them are fastboot versions the second actually states CSC within the firmware version/name and since my mobile will show CSC I downloaded that as my second option


Et bien bonjour à tous j'ai actuellement un probleme avec ma tablette acer voila, quand je l'allume il y a le logo et acer et puis en haut à gauche c'est ecris "booting failed Bootloader vjb-d0ca683: starting fastboot USB download protocol", je peut meme pas acceder au menu recovery. Aucun root ou modif a etait effectuer sur ma tablette.


Je précise que je n'ai fait aucune modifs et que c'est arrivé comme ça du jour au lendemain. Je n'ai pas accès au recovery avec la combinaison de touche ni au mode fastboot. Seul chose que j'arrive a faire est de me mettre en apx mais là encore le logiciel acer software update utility ne fonctionne pas et windows me met un point d'exclamation sur le peripherique apx et [color=red]qd[/color] je fais mis a jour des pilotes il ne trouve rien :-s De même le Hard reset ne fonctionne pas. 2ff7e9595c
