Fastboot mode completely absent?

[Darklurker]

Hi folks,
I was gifted a Micromax A092 a few days back. Quad core, 1GB Ram, Jelly Bean 4.3...not to shabby for ~100$....

But that was before I got around to modding it. Well after somehow rooting it and installing SuperSU, I can't seem to get fastboot mode working on this damn thing. I have doubts whether it even has one. The Vol down + Power button combo gets me to the logo screen where it stays till I am forced to pull the battery out to reboot.

Now the phone does get detected under Device Manager even when its stuck on the logo screen and I can even install drivers to get it to show up as Android ADB Interface or Android ADB Composite Interface but fast boot refuses to detect it even though adb does when connected normally.

Well here's a list of things I have tried:

15 seconds ADB Installer - check
Minimal ADB and fastboot - check
Android SDK with google drivers and unnecessary packages - check
Universal naked drivers - check
Modding the inf files with my devices hardware id's - check
Pdanet+ driver installation method - check
Mobrobo/Mobogenie - check
Manual driver installation - check
Different USB cables - check
Few other random hacks - check


Later gave adb sideloading a shot hoping I could flash a custom recovery onto it via command prompt. No dice there either. Being unable to flash anything means I am still rocking "android system recovery 3e" as my recovery mode which in turn means the dreaded signature verification failed message trying to install 3rd party apps in recovery and sideload mode. I have also tried installing a couple of these custom recovery modes via .bat files but I guess its failing due to the same damn signature verification reason.

Now I know all phones don't ship with fastboot mode but given that this phone was released just a couple of months back and 2 year old inferior phones from Micromax have said feature gives me hope that maybe there indeed exists a way to flash it.

So a little help please guys. What am I missing? Or is it my phone that's lacking? Thanks.

PS: Also my phone's got a Qualcomm processor unlike most other Micromax phones, even more expensive ones that are powered by MediaTek processors.

Hi Darklurker,
Some devices don't have an active fastboot mode and I'm not 100% sure if the MicroMax a092 does for sure our not.
Just some suggestion but have you tried connecting your Micromax to your PC with usb debugging enabled and then open command prompt and start an ADB connection and then type:

adb devices

If its connected properly it will list the devices serial #

adb reboot fastboot

fastboot devices

If the device is connected in fastboot mode it will lost the devices serial # and fastboot is then working.

You could also try and type in Command prompt :

adb devices

adb reboot bootloader

To see if it will boot to bootloader/fastboot mode then type:

fastboot devices

If fastboot is working it will lost the devices serial number.

It's possible that the PC drivers may not be installes properly. You might also want to try and either uninstall and then reinstall the PC drivers or a whole new set of drivers all togethet. Take a look here for the Micromax a92 - Welcome to the ./downloads/Micromax/00_A Serie/A092/Tools/Drivers/ folder of GsmHosting support area

And also here, it has Micromax USB drivers and Micromax PC suite -

I also read and I'm not sure if it works but to enter into fastboot mode... first enable USB debugging in settings/developer options/ then you power off the device and remove the battery and then press and hold down the volume (+) up button and then connect the USB cable to you PC, it should boot to fastboot mode. You may have to also reinsert the battery after connecting it to your PC, for an active connection and the try the fastboot command promps I posted below.

Or try this fastboot mode, press the Volume Down (-) key + the Power button for a while till the Micromax logo pops up and then connect the USB cable.... It should just sit there displaying the logo looking like the phone is hung but its apparently it's supposed to be in fastboot mode, so try opening command prompt and running the fast boot commands I posted below.

Instead of using fastboot mode... Alternatively you might be able to install it, by downloading and installing "BusyBox" by stericson and the "Terminal Emulator" app.

You may have to go into the drivers file and edit the INI file and add your Micromax a092 to the file for fastboot to actually work... I had to do this with one of my devices too.

Hope this helps and gets you started in the right direction ! If you need any more help just let me know and I'll be happy to help!

Hi xdrc45, thanks for the reply.

Having checked a million times to see whether its enabled after unlocking Developer options, I can assure you that USB debugging ain't the problem.

The adb commands you have listed all work as I can see my device's id and I can get it to reboot normally as well as in bootloader mode but once it gets into supposed bootloader mode is when I hit a brick wall.

The fastboot commands don't work. It just sits at the logo screen and only gets detected by Device Manager. Now like I said I can install drivers in this hung mode and I have tried every version of drivers known to man but fastboot won't respond.

Now having rooted, unlocked and flashed an Xperia M just prior to getting started on my phone, I am adequately familiar with adb/fastboot commands. I have plugged the M back in fastboot mode to see if I was doing something wrong but it gets detected properly which means my adb/fastboot installations or commands aren't the issue I am guessing.

The drivers you have linked to are one of a dozen versions I have already tried unsuccessfully.

About the 2 ways you mention about getting into fastboot mode - the second one is what I have been unsuccessfully attempting. I press the button combination you have stated and it gets to the logo screen and stays there. I then connect the USB cable and Windows detects the phone but unfortunately fastboot doesn't.

Now the first method you mention is something I haven't heard of. That's the key combo to get Xperia phones into fastboot mode isn't it? Of course the Xperia phones still have their batteries inside. How do you get a phone to boot up without batteries?

I have Busybox installed on my phone but I am not aware of how to use it to install recoveries. Also Terminal Emulator is another app I am totally unfamiliar with. Would you kindly educate me a little on these two apps?

Also like I stated in the OP, I tried editing the ini file with my device's ids but no luck. As I understand, you have to add those 2 lines of hardware id's under two sections correct? I read a post describing it and did it exactly like it was mentioned there and then manually pointed the Device Manager in the direction of the modified ini file. Please let me if I am doing something wrong or if there's another way.

Again thanks for the detailed reply. Much appreciated.

Also forgot to mention - there's some haphazard description on how to flash a stock ROM on this phone via a .bat file. Here's the procedure:

Flashing steps:
1 - Power on the handset and connect to PC.
2 - Install driver.
3 - Double click on below icon and it will flash immediately.
8x10_fastboot_all_images.bat
4 - After flash, handset will restart automatically.

Here the code that I am guessing needs to be in the .bat file:

Spoiler

@echo off

adb reboot bootloader

echo for not erase modemst1 and modest2

rem fastboot flash partition gpt_both0.bin

fastboot flash aboot emmc_appsboot.mbn

fastboot flash sbl1 sbl1.mbn

fastboot flash tz tz.mbn

fastboot flash rpm rpm.mbn

fastboot flash sdi sdi.mbn

rem fastboot flash fsg fs_image.tar.gz.mbn.img

rem fastboot flash modemst1 dummy.bin

rem fastboot flash modemst2 dummy.bin

fastboot flash modem NON-HLOS.bin

echo for not erase bt and wifi information

rem fastboot flash persist persist.img

fastboot flash cache cache.img

fastboot flash usbmsc usbdisk.img

fastboot erase splash

fastboot flash splash splash.img

fastboot -S 256M flash system system.img

fastboot flash recovery recovery.img

fastboot -S 256M flash userdata userdata.img

fastboot flash boot boot.img

fastboot reboot

Seeing a lot of fastboot commands in there which could mean there indeed is a fastboot mode in the phone or I have a lemon.

In any case, 3rd rate support from the company for a phone just a few months old. Since I ain't a complete novice, all this is not totally alien to me but how is a grade A noob supposed to make any sense of this? The code is not even on the pdf describing the flashing steps! I had to get it someplace else! Pathetic considering they have proper .exe drivers and support guides for much older and inferior phones. I mean I had to install the phone drivers via Moborobo after hours of frustration to finally get it detected via adb. Aaah what can I do...it was a gift :dontknow:

first download these driver use this link d-h.st/ZUh and extract it. switch on phone in fastboot mode and connect to computer now open device manager and you see "Android" with yellow icon right click and select update driver now select second option and choose manual install on next page select all device now select have disk and click browse and go to extracted folder and all win now select winusb inf file and click OK and its done. its lenovo phone driver but it works fine.
