[Wing, P4350 Herald Upgrading] itbmd:
Hey there,

A friend of mine just told me about flashing ROMs literally a few days ago. I did my first successful flash just yesterday and I am very happy that I did. FYI, yes I am using a stock TMobile Wing from 2007.

Rom's are not interchangeable across different phone models as far as I know. So you need to get ROMs made for the wing a.k.a. the Herald. Any Rom for the Herald should work.

Just remember one thing that I forgot to do, make sure that you back up your data. I forgot to do this and lost all of my data. Luckily, I did not have any pictures or music that I was too sad to lose. However, I did lose my contacts. Again luckily, I had an old Sim card from last year that had my contacts on it, so I was able to get back 90% of my phonebook, except for a few people that changed numbers or new contacts. So be sure to save anything you want to keep somewhere else.

I am pretty technically savvy, but I must say that flashing the Rom did take me several hours. The process itself only takes about 10 minutes, but it took hours to figure out what type of Rom I needed and how to exactly flash it. You will see many people trying to tell you that you need to know your IPL and SPL version, and there is no way to know this until you start flashing! It wasn't until I did my first accidental flash that it showed me this information, and this ended up being my first successful flash. After trying for several hours the night before and not succeeding, I guess that's why it slipped my mind that flashing successfully would erase all my data.

The one that actually worked for me was the Canonyang Rom. In the link below please look at post number 216, and you will see a link to download the ROM that worked for me. The file is "HardSpl_WM6".

I tried to flash directly to open touch, and no matter what I tried it was not successful. When I accidentally tried this Canonyang flash it worked successfully the first time, and after that now I was able to flash to any other Rom.

I am currently running open touch light version 6.5 because I read in another thread that it's supposed to be the fastest. I don't need a lot of features so I'm happy with what it has, and it is much, much faster than the stock T-Mobile Rom.

Since you are now getting it, yes, warranty is an issue for you. I am very new to all this, but from what I gather, once you flash, it does void the warranty. Perhaps someone else can answer if there is a stock TMobile rom, that you can flash back to. However, since the roms are digitally signed, I'm not sure that by even doing that, if TMobile can tell you modded it, and therefore elect not to honor your warranty. I guess that's a risk you have to decide if it's worth it or not. IMHO, I found out about rom flashing this week, and my warranty was up last month. However, if I had found out about this during my warranty period, I would have still done it. The Tmobile stock rom is sooo slow, compared to these roms. If you've never used these roms, you'd think like hey, it's got some bugs, but it's not that bad. But if you've used them, you're never going back to stock rom again.

I apologize if there are any typos, as I am using voice to text recognition software that I am testing. I thought I'd help you out by writing this as well as I test it. Good luck and let us know if you have any questions, we're all here to help.
