Try booting the tab to recovery using this method here: How to Boot Bricked MTK Android to Recovery Using MTK Droid Tools and then, you can flash your Custom ROM from there.

saibinc:

Custom ROM does not come with custom recovery. Since Custom ROM are being flashed from recovery level rather than Pre-loader or Boot-loader level, so, overwriting the recovery is not possible with Custom ROM.

Maybe in MTK devices where the kernel sources are closed sourced.
The recovery contains its own Linux kernel, separate from the kernel of the main Android system.
If you flash a custom ROM you overwrite the kernel, unless the ROM doesn't come with a kernel in the first place.
All CM and most AOSP based ROMs come with their own recovery which overwrites the existing after reboot.
The few time a ROM doesn't overwrite the existing recovery is perhaps if it's stock based, and you might have to flash via Odin, or if it doesn't come with its own kernel.
I'm talking about Samsung devices.

saibinc:

Even with root access, such problems are not resolvable. I had that experience with an LG android. I had to flash it to sove the issues.

Similarly, several other Tecno and Infinix were solved by flashing.

Some users reported the problem persisted after flashing.

The trick is to disable the apps, not uninstall them.

I meant broadcasting my music to an FM radio. It will broadcast wateva music file dat i'm playin on my fone to a radio.

Ah.
If you want to do that OTA then you need to have your own radio station.
However there is a way to do that with a wire, if your FM radio has an AUX port then you're in luck.
Connect the device to the radio via a wire (the long wires in some headphones) into the AUX port.
You might need to change the mode of the radio to AUX
The radio then acts as a headphone or speaker of sorts for your device.
Them whatever you play in your phone plays on the radio-- even calls.

If your radio doesn't have an AUX port check if it has a micro SD slot where you can insert your memory card and play your files from.

Everything is online now.

I will hv to look underground, u dont knw wat it can do

Karmanaut:

If you can boot to recovery your problem is half solved.
Just get a PC with ADB installed.
Then

adb push

the build.prop file from the same model of phone to your phone.

Yeah...But I can't boot into recovery only factory mode and in there I cant find the "clear emmc" option

Was USB debugging turned on beforehand?
If so boot into factory mode, connect your device to a PC with ADB installed and push the new build.prop to your device via ADB.

Alright...but how do I go about that....
1)where do I get the build.prop to modify
2)Windows is telling that my device is an unknown device...Although it connects to the PC and I see it as a removable drive but after some seconds....P.S..Device manager tells me I have no drivers installed...so what drivers do you recommend for my Mt6572 ubifs(not adb drivers installer)....Thanks a lot....

Gyrados:

From another phone that's the same mode as yours.

That's a major problem....I don't know anybody who has this device.....How do I install the drivers ...I ran the setup bit still...Help me....Because it tells me that the.inf file has no info of my device..

Gyrados:

Yes you can, but It'll be the modified one that's causing your device to bootloop, if you know the changes you made to the build.prop you can pull it from your device via ADB, edit it, then push it back to your device.

Karmanaut, thanks for all your help towards this page, it hasn't gone unnoticed.. My problem, I rooted an old Samsung galaxy note 10.1 2012 WiFi edition and flashed bliss pop custom rom lolipop on it, unfortunately to charge this tablet now is an absolute pain. On stock, I will usually plug it in at midnight, and by am battery is 100%, but on this rom it can take anything up to 13hours plus. And this is just 7000mah. The main issue now is the battery indicator is stuck on 4% and it won't go any further.. I have downloaded the stock OS from sammobile but I don't have enough charge to even boot up.. My daughter wan kill me, na where she dey watch her cartoons on YouTube.. Any solutions please?

Have you tried a different charger?
The problem should be from the kernel of the stock ROM.
You can flash a different kernel or ROM entirely.
Turn off the tab, charge it and see if it comes up a little.
10% should be enough.
Then boot to download mode and flash the stock ROM.

error....access denied.....Windows sP...

XP?
You need to activate the hidden administrator account.
Right-click "my computer" and select "manage". Expand "local users and groups". Select "users". Now right-click on the administrator account and select properties. You can enable it in there.
Or you can Upgrade to Windows 7.

Which custom recovery did you flash on it?

bigiyaro:
thanks boss, my tab is up n runnin.

You're welcome .

Karmanaut:


Maybe in MTK devices where the kernel sources are closed sourced.
The recovery contains its own Linux kernel, separate from the kernel of the main Android system.
If you flash a custom ROM you overwrite the kernel, unless the ROM doesn't come with a kernel in the first place.
All CM and most AOSP based ROMs come with their own recovery which overwrites the existing after reboot.
The few time a ROM doesn't overwrite the existing recovery is perhaps if it's stock based, and you might have to flash via Odin, or if it doesn't come with its own kernel.
I'm talking about Samsung devices.

Even Custom ROM for Samsung devices do not come with Custom Recovery. Maybe you are mistaken boot.img with the recovery.img.

It is the boot.img that when flashed, overwrites the kernel.

Karmanaut:

Some users reported the problem persisted after flashing.

The trick is to disable the apps, not uninstall them.

ONLY rare ocasions, the infected apps remain silent when disabled. It is safer to flash them than to disable them.
There was case a client reported to me. He didn't want to flash the phone because of his BBM Chat history until eventually, the phone began downloading some apps, installed them itself and eventually, the phone went off and never came on until I flashed it for him.

The phone in concern was Tecno H6.

If they're disabled then they can do no harm and there's no need to flash.
