Micromax AQ4501 Bootloop - Android Q&A, Help & Troubleshooting

Hello
I have Micromax Canvas AQ4501, its settings crashed, so I did factory data reset and cleared cache using recovery mode since then it's in boot loop :crying: I tried to flash using sp flash tool but my computer is not detecting device I tried again and again by installing all available drivers but it is not happening I tried to install update from sd card using recovery mode but it says E:signature verifaction failed I tried to flash using cmd but its not detecting device.
Please help if there is any other way, if anyone knows how professionals(at Micromax service centre) do it, since February 2016 it has happened 5th time if anyone knows why this happens please tell me I will take care of that from next time.
Thank you for your precious time.

Lenovo A6000 Stuck on Boot

I tried to install a new rom(cynogenmod 11 from xda forums) in my lenovo a6000 which i god a day before on my birthday. it had lollipop os and i installed TWRP recovery in it. but the instructions for installing rom said to clear data. dalvik, cache before installing and the twrp cleared cache and delvik cache but then it had been over 5 min and it still stated -"formatting data by mounting(bla... bla...) method". so i just reboot the phone by removing the battery and booted in the recovery again. i tried to clear them again but this time all of those three stated mounting problems while clearing. i went on installing the rom but it stuck too stating only these lines:-
1>no md5 checksum found.
2>skipping md5 checksum(bla.. bla...).
so i did the same mistake again and removed the battery to reboot but now it just shows the lenovo logo on bootup and nothing happens thereafter except frequent restarts. i tried to connect it to pc to load recovery via minimal adb and fastboot but the phone is just charging itself via usb cable and not connecting to the pc no matter i reinsert the battery.
i dont want to reach the service center or my dad will kill me for damaging a new phone. please if anyone can help then reply soon or i am gonna screwed.
Just press volume - & power key same time , now your phone is in boot loader mode now connect USB & flash twrp recovery through minimal adb method & restore your backup

To be continued
Oh I somehow figures it out, I pressed all the keys I.e. volumeup + volumedown + power key even after the Lenovo powered by android logo and it suddenly booted into recovery. This method worked in my bq s37 I didnt expected it in this case. BTW thanks for your support and can u please help in in a new case related to same. The twrp recovery for a6000 lollipop is not installing cm11 properly. Every time I install using the same method as mentioned in a post of XDA. After installation it stops on the same screen:- Lenovo (powered by android) and after that no reboot just that screen forever till the battery dies. I even tried cleaning /system before installing cm11 ROM but still no progress. Please help!
You cannot install cm11 on top of stock Lollipop rom
Revert it back to kitkat flash recovery Then install cm11
Get it of one problem and the other awaits. Now when installing KitKat rom (the official one from techotally) it said unable to mount /data. I followed some tutorial which asked to write some codes from adb shell menu. One of the codes said something like -kill recovery, after what my recovery frooze. I restarted the phone by removing the battery but nothing is happening after that. I am trying to restart it in recovery or in bootloader or even normal restart. Everything in vain and nothing is shown on screen and not even boot logo or the lenovo powered by Android screen. But in my pc some drivers started installing out of which two were installed and two weren't please help.

You are not correctly getting it my friend. i said the phone doesnt boot at all no matter what key combinations are tried. it simply doesnt start. no display no vibration no sound nothing just the pc detects it as qualcomm hsusb.........
BTW in the mean time my father got to know about this condition. he scolded me but asked to fix it if i can before going to service center. i was just thinking what if they got to know that i rooted the phone? or installed custom recovery in it? anyway if i am to go to the service center the statement given by me will be that:- while updating via ota from kitkat to lollipop the battery died and this all happened. an yes i live in INDIA time zone=+5:30 GMT so tell me when i can find you online(time?) my friend so we can try fixing my phone also it will be help full if we become friends on facebook? so that we can chat live clearly and for as long as we want. so that i can ask you about any problem occouring in future directly without creating a forum in xda. so please buddy please....... .... .. .

You can still connect your phone via USB....copy your custom rom((probably a stable one) files into the phone and boot in recovery to install that rom again...best of luck..

Help!!! My infinix note 3 x601 always boot to recovery

I have an Infinix Note 3 X601, updated to Android N, Rooted and Philz Touch 6. 59, 0 custom recovery installed. Problem began when I tried to factory reset it from within the settings, the phone rebooted to recovery to wipe the data, and since then it wont boot to system again, whenever i try to boot it to system, it will go to recovery. if i connect it to pc, the pc wont recognise it, the pc will show a message that the USB device is not recodnisd, and the phone will boot to recovery again.
i tried to reflash the stock firmware using sp flashtool and it always fails as the system will not recognise the phone, even though i have the required mtk drivers installed.
i tried to flash this https://androidhq254.blogspot.com.ng/2017/04/mad-aosp-n-711-for-infinix-note-3-x601.html and http://bbs.infinixmobility.com/thread-149453-3-1.html custom roms using the custom recovery, they all fail mid way.
i will appreciate any help i can get in reviving this phone. thanks in advance

thanks for the reply, could you elaborate on the "qpst tool" pls, i dont know much about it
qpst is a kind of software
that enable us to use a port in the phone to install firmware and others software when something like this happens...
some manufacturers like Samsung manufacture in such a way that this cannot be used,
depending upon your manufacturer and the processor(it mainly support snapdragon i think) you may get if you search in Google.
