Hii there!
I am relatively new to this so I'll explain everything I know and tried so far.
I have a Micromax AQ4501 Android Phone running marshmallow. Recently My phone started acting strange like apps suddenly crashing. Yesterday, My phone ran out of juice. After charging it for a while, I switched it on and it was stuck on a boot loop. It has happened many times before. I usually fix by flashing it with stock ROM available on Micromax website. But now the case seems different. I first unlock the bootloader by going to fast boot and by using "fastboot oem unlock" then "fastboot -w" then when I restart my phone I should get a Micromax boot logo with oem unlocked written below. I then went to recovery to check something out. When I entered recovery, It showed E: cannot mount /cache (Invalid Argument). I tried to factory reset in recovery menu, it still showed the same thing. Even /system couldn't be mounted. I cannot even flash the ROM as I cannot unlock the OEM. I read few forums and many suggested to try it with different recovery. As I couldn't flash it, I used Android One Toolkit and booted into TWRP, CWM and Philz8 recovery. In all those, I got the same error message. In TWRP, the internal memory showed 0MB and in the mount selection, I the system, data and cache option were grayed out( Couldn't select them). I even tried to wipe cache method, still no luck. So From boot loop, now my phone is bricked. I have attached the images regarding this. Images 1 and 2 are of stock recovery. The remaining are from TWRP recovery.
Can someone please suggest or guide me through how to restore my phone. Here is my email just in case [email protected]
Since this is my first post I cannot share the link to my drive. Upon request, I will surely share those images.
Thankyou
Shamanth S

Hi Guys..
I used this guide to repartition my internal storage so that I could squeaze some extra GBs and it worked for me the first time and I set 500mb for my system partition. Things were going great till I decided to flash lollipop on my S3. I came to realize after the first attempt of flashing lollipop that I need to increase my system partition coz flashing was failing with status 7 error so I repartitioned again and this time I gave 700mb to system partition. This time flashing went fine but while starting the phone it got stuck at "Encryption Unsuccessful" error message as shown in screenshot.

I am getting the same error message flashing any CM rom or after restoring my backup.
Resetting phone doesn't help either as same message appears again, factory resetting through recovery doesn't help either. If I flash stock rom again using provided pit file through odin I am able to restore my backup and use my phone normally but the same error messages returns if I repartition my phone to any different size than stock size.
So currently I am back to stock size by flashing pit and stock rom and then restored my CM11 backup.
It's really not mandatory for me to really repartition my phone and I won't unless I know what's the cause of this error message and how to fix it.
Can you guys suggest me what's wrong and how to fix this error message?
P.S. - One thing to mention here that after I flash the repartition zip and phone rebooted to recovery after that I clear all partitions except data cause I was getting mounting errors for data and I simply flash a rom and rebooted my device. Phone stuck at boot animation so I went to download mode and flash stock rom with provided pit file to revive my s3.
Also please note that I didn't do anything related to Encryption to enable or disable it.
Thanks.
Never play with the partition arrangements of this phone, the emmc chip is very fragile and mostly ends up with a hard brick.
That's why I stopped fidgeting with it anymore but just want to know the cause of this error.

I don't know its a virus or what but suddenly my phone was not responding. I had a doubt that it was a virus so I decided to wipe everything but my recovery also stopped working.
How can I solve this ?
What ROM are you using?I suggest flashing a new ROM This time wipe everything except SDcard if it fails then wipe SDcard too.
nothing is working :/ i tried adb and tried to mount the system but it is failing. tried to wipe through twrp nothing working.
update twrp to 3.0.0 but still same
Now I have done "fastboot erase system" now my os is not starting and i am unable to flash another through adb
Please Any suggestion ?
anyone ?
if u erased system partition then os wont start as u have erased os files. Now the best thing to do is wipe all partitions from twrp. download a new custom rom and flash it through twrp. if u were using stock rom and want it u may get that from forums too. if u have a working nandroid backup ( which i feel u dont have) of previous rom u may try that
i can't format or wipe or do anything from my twrp.
EDIT: you can see it in the video

Hey folks,
I think I briked my Phone last night but I dont give up on it.
What happened: I tried to flash a new ROM because my current Custom ROM didnt appeal to me at all. So I went into TWRP and made a normal wipe. Then I tried to install new new ROM.zip. The first odd thing was that I couldnt navigate to the download folder on my external sd card. The good thing was that the old ROM.zip was available for flashing so I decided to flash the old ROM anew. And then...nothing happened. I couldnt intall the ROM. Not even the Gapps.zip was able to be flashed.
Then I thought I could try it via Fastboot on the PC (I have a Motorola x Style/Pure) and googled how to do it. I found a command to install a .zip and tried it. But it didnt work: It said smth like 'Bootloader denied'. So that wasnt the ways to go for me.
After that I went back into TWRP and looked on the command line. And there was smth odd aswell. I said: "Failed to mount '/cache' (Invalid argument). The same with 'data'. The internet said I should format (not wipe) the storage in TWRP. I tried it and although it said that it was successfull nothing was...TWRP is still unable to mount cache and data.
I found out that it has smth to do with the encryption but idk.
So that is my problem: I cant install anything. I cant format anything.
Pls if you have any idea on this pls tell me. I already ordered a new phone but it would be nice if this phone didnt become a paperweight...
And thank you if you read till here. Aaaand sry for my bad english

Hello everyone, just got hands on this phone, but it came with Android 4, so I decided to flash it.
Step by step what I did. Had a stock ROM, flashed a TWRP in, then flashed in the Cyanogenmod, it was working fine, but the SIM wasn't working, tried to put the NVRAM file in manually, didn't work and it was deleting itself everytime.
So I reflashed it back to stock and notice the SIM isn't working still, found the bin file on the internet, flashed it into the stock ROM, everything was working fine.
So I went back to flashing in the custom ROM along with the NVRAM.
The thing is that somehow it made two locked folders - protect_f and protect_s and I got no idea how to get rid of these, TWRP is giving me error, that it count mount these folders and after flashing in the CNM it's not booting.
I can still flash back the stock ROM with the stock Recovery and it works, but as long as I flash in the TWRP it's not booting.
Settings that I used -

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
My question is how do I get rid of these two encrypted folders, so TWRP can flash in the CNM properly or what do I do?
I'm trying to fix it for 5 hours already and I'm losing my mind.
EDIT: Currently I'm running stock ROM and fixed my IMEI via the Engineering Mode. The two locked partitions are still there.
Still I don't really like to use Android 4 in 2017 and would like to flash in the CNM, but yet again I need my IMEI to work.
EDIT 2: Seems like my EMMC is locked or something? When I'm trying to flash the ROM from recovery it gives me - Failed to mount /protect_f (invalid argument), same thing with /protect_s and after that I'm stuck on CNM animation, not a bootloop, but won't boot. The thing is that it was working before I went back to stock ROM to get the SIM working, now I just can't get the CNM to work.
EDIT 3: This is the stock firmware backup done in MTK Droid Tools, as you can see, there are these protect_f and protect_s folder, which I need to get rid of from my phone (I guess?)
Any help is appreciated!
Hi, i am new to this. I have galaxy s3 i9300.
My gf was using this phone on stock rom 4.3 or 4.4.4 and it was really awful. I am iphone user, but i do know a little about phones and all that so i tried to install some custom roms.
First i tried lineageOS 7.1.1, it was laggy, camera constantly crashing etc.
So i tried to install android M cm 13.0 unofficial teamseek v12.3. Less laggy but after installing telegram app, os crashed. Some trebuchet proccess was constantly rebooting phone. Messenger app could not use camera, black screen. And once phone could not see storage. Wiping cahce could not solve the problem. Meny restarts, nothing. I pulled out sim card and it boot, but after some time trebuchet crashed again and boot loop continued.
So i tried 4.4.4 kitkat cm-11-20160115-SNAPSHOT-XNH0E0O00N and same problem, messenger cant see camera app.
Then i tried 5.1 blisspop and it was good, messenger can see camera, little lag. And then it suddenly shutsdown on the charger. Tried restart - boot loop. TWRP cant wipe anything or mount anything, storage 0. Phone cant see memory card either, but i know its working because i put it in the other S3 which is in boot loop too .
What to do now, other s3 cant be recognized by the PC but can see memory card, and this s3 can be recognized by the PC but its shows empty.
Then i tried to install official 4.3 for s3 via Odin. Installed successfuly but same problem, cant mount any partition. Newest TWRP installed.
I am stucked here now:
