Unfamiliar with What the Tech?!! Series? Well, check out the previous issues below:

What the TECH template.jpg

Hi Everyone!
Happy New Year! and I'm back with another Issue of What the Tech?!

I've always been a Flashaholic ever since I had my first android phone (LG P500) way back in 2011. I remember then that I was frequent checker of XDA forums for new ROMS, in every device that I've own through the years. I even flash twice or thrice a day, checking and testing every ROM out there for my device.

But it always made me wonder,
would I eventually damage my Phone if I frequently flash, wipe, and write ROMs and flashable zips? What the TECH?!

To attempt answering the question, we must first understand how flashing works.


What is Flashing?

Flashing is the the process of over-writing existing data in your internal storage device with new data.

over ROM.jpg

In Android terms, Flashing mainly refers to the way we install ROMS and flashable ZIP tweaks, to our device through 2 ways:

a.) the Recovery, or b.) Fastboot
Learn more about them here:

As we know, our devices uses different types of storage, but it usually uses an internal storage device, called a flash memory storage, where the Android System is contained.

My MI 3 for example uses a 16GB Sandisk Multi-Layered Cell (MLC) NAND flash memory.


As Wikipedia defines it:
Flash memory is an electronic non-volatile computer storage medium that can be electrically erased and reprogrammed.
The NAND type flash is primarily used in main memory, memory cards, USB flash drives, solid-state drives, and similar products, for general storage and transfer of data.
But, one significant disadvantage of flash memory is the finite amount of read/write cycles in a specific block.

So now, the question is,
can the flash memory handle frequent, and excessive wipe and flash of ROM's and Fastboot?

Just like any other electronic device, a Flash memory has a lifespan, or "Memory Wear"

....(a) flash memory has a finite number of program-erase cycles (typically written as P/E cycles) per block. Most commercially available flash products are guaranteed to withstand around 10,000 P/E cycles (for MLC) per block before the wear begins to deteriorate the integrity of the storage...

Should I be worried about Flashing Frequently?

Honestly, No. Flashing wont be a problem.
Whether you're Flashing ROMs daily or just copying files to your devices, or simply downloading stuff to your flash memory, you are still using up the life-cycle of your flash memory.

While true, your device's flash memory will eventually fail in the future, but you've probably replaced your phone with a new one at that time. Besides, different Wear Leveling techniques are being used to prolong the life-span of your flash device,

With Wear-leveling, for example: My MI3 uses a 16GB Sandisk Multi-Layered Cell (MLC) NAND flash memory. MLC NANDs is generally rated with read/write endurance of 10,000 cycles. So, let's say I flash a ROM (usually 500MB) every 5 minutes, continually. That would amount to 57.6 GB per day. And the total number of days the drive will last before becoming unreliable is:

(Capacity of the Flash Memory x P/E Cycle Rating)/Total of Data transfer per day) = Theoretical Lifespan (in days)


(16 GB x 10,000 P/E Cycle)/57.6 GB per day = 2778 days, which is about 7.6 years of continued flashing every 5 minutes, before my flash memory dies on me.
Flashing a ROM daily, it would take you 876 years before your flash memory dies.

con03_02.jpg wl.jpg

therefore, 10,000 P/E cycles is pretty much just a theoretical number.

I've probably flashed ROMS hundeds of times in my LG P500 I had in 2011, and it's still working just as it was.

In Conclusion:
Over-flashing will not damage your device (hardware-wise), but Memory Wear will, ..... over time.

But what do you guys think? Is there really a thing as Over-flashing? Participate in our debate below!
