Micromax A94 stuck in boot loop - General Questions and Answers

I rooted my Micromax A94 phone and to take a backup tried to flash cwm recovery (ClockworkMod) on it. But it got flashed to the boot not to the recovery. So now whenever i reboot it goes straight to cwm not regular boot screen. I tried flashing stock rom through cwm but it says cant mount sd card. I wiped everything possible. Still no change. Also i cant mount external sd either. If i press reboot now button it reboots back into cwm. Please Help Me.

But will it still work if the phone is switched off?

Your device should be in fastboot mode.
Switch off device and hold.
Power * vol up button for 30 sec and it will be in fastboot mode.
Now connect it to pc . Start cmd and type command.
Use cmd from same folder where your boot.img exist on pc.
Boot.img can be found on any nandroidbackup you made just copy that in a folder ans get to work

there are 2 way
1 > Boot by press up volume & power baton and set reboot And it's done ........
2 > make a Flash your mobile by pc on service center ............

Going to fastboot by either method is correct.
Either use rockers. Or asc command adb reboot bootloader.
Both are correct

I did that now all it does is load the starting logo and not do anything, I can still go into fast boot mode though. If I use the fast boot update command can I flash a new rom and will it overwrite everything else? Including boot.

First you have to remove boot, recovery , system, data , user data and then flash the mew rom.
Search for that on google

No recovery after using htcdev

Hi all, I recently unlocked my desire s using htcdev which all went ok. Then rooted with superoneclick. Installed rommanager which went through the process of installing clockwork recovery into flash which appeared succesfull.
Problem I now have is that when I try and use recovery mode to say backup my Rom, after reboot I get the phone symbol with exclamation mark like recovery is missing. I then have to pull the battery to get it rebooted (which always worries me)
Even starting the recovery feature from the boot menu does the same thing. Any ideas ?
Sent from my HTC Desire S using xda premium
you have to install recovery tru fastboot i.e
get the recovery image and paste in d folder in ur pc where u have fastboot
conncet ur fone to the pc via usb (ensure u have enabled USB DEBUGGING on ur fone)
from ur pc, open terminal or command prompt and navigate to the folder where u dropped the recovery.img
run this command:
fastboot flash recovery recovery.img
*if the name of the recovery image is different ensure its specified in the command e.g fastboot flash recovery <name of recovery>.img
cheers
---------- Post added at 01:48 PM ---------- Previous post was at 01:40 PM ----------
i forgot to add....
after ensuring ur fone is USB DEBUGGING enabled;
connect ur fone to ur pc and restart fone into hboot...u can do this by powering off ur device and then restarting by pressing the volume down button + power button at the same time.
select Fastboot or Hboot.... it shd change to FASTBOOT USB
you can now run d commands on ur pc

Flash boot loaders and recovery without fastboot or root

Hi everyone
Is there a way that I could possibly flash wkparks bootloaders or a custom recovery without fastboot or root, this would be very useful because my power button doesn't work

If you have any recovery installed, install the one in this post: http://forum.xda-developers.com/showpost.php?p=40249156&postcount=7
After that, there's somewhere in the forum a zip file with wkparks bootloaders that you can flash in recovery, search it.
Thanks but I keep getting an error, remember I am not rooted have stock bootloaders have no recovery and cannot get into fastboot mode because my power button doesn't work.

Yes, if you're not rooted you can't install recovery...
I'm not sure if there is a way to enter fastboot mode without power button, try searching the forum for that.

If you have fastboot installed on your phone; pull your battery, hold Vol -, plus 3D and slide your battery in. Fastboot menu SHOULD pop up. Use Vol+ to select fastboot and your phone should reboot in fastboot mode 0.5

i have stock bootloaders and cant get into fastboot
This method requires no use of power button whatsoever. 1st: Do you still have your omap drivers in tact? If so try this tool--> http://forum.xda-developers.com/showthread.php?p=37893247 (if not there is a link for drivers there as well) if you have used fastboot before you should be good; I have never had to reinstall my omap drivers once they were intact until I formatted my CPU; all you should have to do is run the bat file in the "all in one tool 1.2" and it will say waiting for omap device...I never had to hit any buttons or anything I just plug phone in with battery out and tool starts to run. Wait 5 sec and pop in battery and phone will be in fastboot on its own. All other tools I've used I had to unplug phone and then plug back in to start fastboot but not with this one. Choose option 8 for ics bootloaders (wkparks) and then flash any GINGERBREAD recovery (options 2-7) I believe 4 & 5 are cwm touch versions. Use one of those or TWRP 2.3 and you won't have to use power or volume to navigate inside recovery...I use TWRP 2.3 option 6. After that hold volume - and 3D on the phone and type in option 12 (reboot) and hit enter. Profit! Blue Fastboot menu should pop up and default boot option will be on recovery, just let it boot up. I hope this works for you.

I tried to use the same "all in one tool 1.2" but the process stops in "waiting for the device". In phone I have the silver/grey logo for some minutes until the phone reboots in sama state as before.
does the tool actually run when you plug the phone in on "waiting for omap4430 device" or do you start the tool, plug in your phone and nothing happens? Fastboot has to flash to get to the "waiting for device" to pop up. If you wait 5 seconds and pop in the battery right when the tool flashes the second time and nothing happens, just pull out the usb cable and then plug it right back in and your phone should come on with grey lg logo (fastboot). If that doesn't happen maybe try re installing omap drivers.

[Q] Reboots no recovery only fastboot

I have a one xl that will reboot after being on for 2 minutes
evita pvt ship s-on rl
hboot-1.14.0002
it is unlocked, but i cant relock it. Every time i try it says fails then reboots. I have also tried flashing twrp and cwm recovery via fastboot, but everytime i try to enter one it hangs on the teamwin screen. I have tried the ruu it reads my phone at first then when it says rebooting to bootloader the phone reboots normaly and get error 107.
Any help would be greatly appreciated.
What method are you using to try to relock the phone? What method are you using to install the mentioned recoveries? Please give as much detailed information as possible.
Sent from my Evita.
To relock i have used fastboot in cmd and typed fastboot oem lock. I have done that 10 times with the same result phone reboots normally and when i reboot back into bootloader it still says unlocked.
To flash recoveries i have used fastboot flash recovery ********.img
fastboot erase cache
fastboot reboot-bootloader
but instead of rebooting to the bootloader it boots normally
What did you do to the phone before all this started happening? Phones don't usually just start doing things like this of their own accord.
Sent from my Evita.
I bought it like this. The last owner said it happend after he installed a rom. I was hopping i could unbrick it with out jtagging it becuase i am still able to fastboot to it.
If you can't get an RUU to work I think jtag might be your only option.
Sent from my Evita.
I've only tried 2.20. I even extracted the system IMG from it but fast boot says it is too large. The only reason ruu won't work is because I can't get my phone to reboot into boot loader. Is there any way I can flash a different boot loader through fast boot.
Just curious, but when you type fastboot devices from the Bootloader, what is the output?
Are you running fastboot oem lock from the bootloader?

Nothing happens. And if I type fast boot OEM lock from the boot I get waiting for devices

If when you type fastboot devices (while in the boot loader) in your computers command prompt, and it doesn't show your HTC device being attached, that means that your computer is not recognizing your phone. Have you installed the HTC drivers? Do you have the newest versions of fastboot and adb installed?
What OS are you running on your computer?

I have the HTC drivers installed. My computer only recognizes my phone when I put it into fast boot mode then it tend me my device name ht253w309354. Fastboot. As for three adb and fast boot versions I do not know.

If you can connect to Google Play store, download recovery tools, if you have time. From there you could try to install a new recovery for your device. With only 2 minutes you will have to be quick though.
Do you have access to your sdcard from your computer?

I don't have time. Every time I reboot I have to renter my WiFi password. Yes I think I do but by the time any thing loads it reboots.

Have you tried to flash a new ROM from fastboot? It sounds like your recovery partition might have been corrupted.
Sent from my One X using XDA Premium 4 mobile app
I can if I turn it on fast enough, but when it reboots I have to turn it back on.
I have only tried flashing a system.IMG I pulled from an ruu. But fast boot said it was too large.

Alright, so I have a few ideas.
1. Try flashing a new rom via fastboot. (the following is based on the assumption that you have adb and fastboot in your path)
Flashing a ROM through Fastboot
So Why Do I Need To Do This?
You don't, normally you would flash a ROM through recovery, but why not have another way? Maybe your recovery partition on your phone is corrupt?
Maybe you just want to say "I learned something new!" whatever your reason here are the simple steps:
To start:
Quote:
Quote:
We need to download the ROM of choice to your computer. Once complete find the folder that rom is in and open terminal/cmd to that directory
(quickest way for windows; just hold shift and right click within that folder > open command window here) of course make sure your phone is plugged into computer and in fastboot mode.
Lets see how quick and easy this really is...
In the command line type:
Code:
fastboot devices
Seeing your serial number means we know all is good
Now lets type these commands:
Code:
fastboot erase system -w
fastboot erase boot
fastboot update superawesomerom.zip
Of course replace <superawesomerom.zip> with the correct file name
and last but not least:
Code:
fastboot reboot
2. Boot into Recovery via fastboot.
Plug phone into PC, connect with USB cable and have phone in fastboot mode, now open CMD/Terminal in the same directory as your recovery image
Code:
fastboot boot recovery.img
Of course name image correctly to fit command or vise versa
Now you are in recovery of choice within your device without it being flashed to your recovery partition. There is a time and a place for everything, can you think of ways this may help you? Sure you can!
This doesn't actually flash the recovery.img... it will just allow you to boot into it. Make sure that you have a good TWRP version.

Recovery update

So can anyone tell me how I can update my recovery I am already rooted just need to update it . do I need to flash it in fast boot or what
Sent from my Nexus 5 using Tapatalk
Connect your phone in fastboot and run "fastboot flash recovery <path_to_recovery.img>" Or if you don't want to use your PC you can use ROM manager or flashify from the play store. Flashify is only good if you have the image saved on your phone and is limited to three flashes a day on the trial version.

Get into the bootloader by powering off the phone. Turn on the phone by pressing the down volume button and the power button at the same time. Rename the recovery you're trying to flash to recovery.img. Plug the phone into the computer and open a command prompt where you saved the new recovery image. Type fastboot flash recovery recovery.img

Did my phone bricked itself? Please help!

Hey guys, I received my OnePlus One today yayy!
BUT. I booted the phone, configured everything like I wanted, installed all the apps I wanted and then I got an OTA update so I figured I would do that too!
The phone rebooted and... stuck on the 1+ logo / powered by android.
I asked around and people on the OnePlus forums told me to boot into recovery and perform a factory reset / clear cache.
I did this and my phone booted again. I reconfigured everything, reinstalled everything and I decided to reboot the phone.
It got stuck again on the logo.
Now though... I can't boot into recovery mode. I asked for help again but no answers... through some research, I installed Android SDK and tried to open a command prompt and type "adb devices". Nothing appears in the list.
Can someone help me? I just want to cry...
Before you can use ADB, you need the ADB drivers. Download the OnePlus One Toolkit and use the feature that downloads and installs the correct drivers. Or you can manually look for them.

Drivers are already installed, the phone is stuck in the boot sequence.
It's detected by both "adb devices" and "fastboot devices". It responds to commands like "fastboot reboot" but since it cannot reboot, this achieves nothing. I can't "fastboot oem unlock" because the phone doesn't load the OS.

Hey, thanks for your reply!
I'm also getting help from the OnePlus forums but here are the latest updates:
I managed to get into fastboot and flash everything (boot, cache, system, recovery etc.). However, everytime I reboot, it still hangs on the boot screen. I have to leave the phone off for about 5 minutes, get into recovery mode, clear the cache and boot into the OS... every... single... time I reboot.
Is there a reason for this? Should I install another ROM (like Paranoid Android or Color OS) instead? Is there a fix to this or is it even software-based?
Unlock bootloader ,flash twrp,flash flashable rom zip.In twrp wipe everything,then go to mount & then uncheck system.Then flash the rom.zip
