Logic behind flashing phones multiple times

[Andrewwelton]

Yes this is true. By stuff left behind I thought you meant files on the internal memory. My bad.
But also, If the ROM you're flashing doesnt modify bootscreens but you're previous one did, flashing multiple times will do nothing to change the bootscreens.

Correct. For instance, the EnergyROM series does not flash a new bootscreen. While some may find this annoying, I use this to my advantage, because it allows me to retain my custom bootscreen in between each update of the ROM. A ROM image is capable of flashing any and/or all of the following: Stock SPL, OS, Boot Screen, Radio. Most custom ROMs only flash the OS. Quite a bit of customised ROMs flash the boot screen also. Some flash the radio to the "optimized version" but many do not. it is expected that if you know how to flash a ROM, you are fully capable of flashing whatever radio you wish to have on your phone, and many users, (such as myself), use a custom boot screen that saves 30s by not having to re-flash your custom boot screen, so many customized ROMs do not include a boot screen.

Ya, again, I see no reason to flash multiple times. I only see a reason to flash a stock ROM between custom ROMs if you want to be sure everything is reset to stock first and nothing carries over.

You're not all alone, I am the same way. There is no reason to keep re-flashing. In fact, you only have 10,000 times to flash a ROM, I could probably get that done in about 3 years. So, flashing a ROM multiple times does nothing but shorten you by at least 1/2.

Thoughts?

Paying Omag to our forefathers back when this technique actually had the hardware to support the theory. Haven't needed to do this since the HTC Apache/Mogul days. The phones had extended ROM's that held the boot image, the device then copied them into "working" memory.

Nowadays, the phone memory is one. It's just 15-20 minutes of their lives...

By Omag do you mean homage? LOL, sorry couldn't resist.

[rstoyguy]

Yeah. It's just one of those words I say alot, and not type very often...

Hi, my name is Brack and I'm a flash-o-holic. Here is what I've experienced. I love flashing different roms and testing them all out to see what I like best. I found that sometimes, not all the times when flashing something gets corrupt and the internet and incomming calls won't work. To solve this problem I flash back to sprint stock then run IOTA, then flash which ever custom rom I want and bang back in business. I'm not sure about flashing the same rom a couple time helps or not. I just know for a fact that flashing back to stock then flash the custom rom will cure some problems.
I'm not a techy or anything, this is just what I found in my flashing experience.

I have never once flashed a ROM multiple times. Don't see a need to. Then again, I never end up with the issues I read others complaining about. Most sound like either unreasonable expectations of the phone/ROM or user error. I flash once and things just work. If not, I move on to another ROM and/or wait for updates.

In on this. I think it's a load of BS too. I've been stuck on one dude's ROM for some time and it's the worst quality of any that I've experienced. The problem is, it's the only ROM I've every used that actually has the things to do what I want. So alot of the minor/annoying hiccups, bugs, etc., I deal with until the next version.

However, on multiple occasions, I have run into scenarios where my phone will suddenly decided to start hard-resetting itself. For a ROM that never touches the radio/boot screens, it sure causes alot of problems in those areas.

"Upgrading" the radio is such a pita considering what you have to deal with at customer support to get your phone working again.
