Un-doing Your Hard Work
 

I work for a company that recently got into repairing and refurbishing HTC devices. More and more often our technicians bring me devices with your ROMs installed. This morning I was given a device with a Swedish Chef/PPCGeeks.com boot graphic. Pretty darn cool, we all had a good chuckle. There's another one on my desk I'm quite honestly afraid to look at.

I have a lot of respect for what you guys are doing here :salute: but let me tell you it's been a pain in the butt figuring out how to un-do all your hard work. ](*,) You see, we have to return these things to factory standard and default before we're done...

Unfortunately, from what I've read here and experienced on my own, there are going to be some cases where this is not possible. Regressing GPS enabled software back to non-GPS, for example.

Anyway, I just wanted to let you guys know that someone out there appreciates your efforts! Thought you might get a kick out of my predicament...

Later, and keep up the good work.

PS-You'd be surprised the number of half-cracked and screwed up devices we get from people that simply didn't follow the instructions you guys post. N00bs.:-P

It is very possible to regress back to nongps roms. I do it all the time. But the nongps rom I install is Verizon. If you have the carriers nongps rom then it is easy.

Re: Un-doing Your Hard Work
 

all that work can be undone with a simple flash of the stock rom... all the gps stuff, reg edits, everything...

its awesome to see a response from a service tech somewhere though...

is that how you found out about pppcgeeks, a splashscreen?? if so, thats awesome...

hope you enjoy everything this place has to offer

Why must you go to Pre-GPS? Most carriers released stock ROMs that include GPS. But, to answer the question flash a pre-gps ROM is not hard at all.

Welcome here :)

Possible, but not reliable. The stock non-GPS ROM is smaller than the GPS ROM, from what I've seen HTC doesn't "erase" memory, they just re-load the ROM on top of what exists. This leaves a chunk of data in memory that the current ROM doesn't understand how to access or use leading to instability.

Cell phone manufacturers typically format memory as part of a firmware update, LG and Moto for example. I don't know if devices designed for Windows Mobile don't do this for a particular reason, I still have a lot to learn.

Think of it as making a mix tape when you were a teenager. You had a crappy old Great White album and recorded Motley Crue and Megadeth and Metallica songs on it after covering up the write protect holes. Unless you used up every little bit of tape at the end of each side there was still a little bit of Great White on there at the end of the other songs, right?

I've had one get squirrelly on me that I couldn't in good concience send to a customer, and a few others that were fine after monitoring for a few days. If I had a better handle on what you guys are doing I may be able come up with a remedy.

Which is why I'm here...

Right, but down-reving radio versions and re-locking the SPL is tricky. Unless I'm doing something wrong...

One of the carriers we service didn't implement GPS, and are hung up on us shipping 6.0 on 6800's. I really don't have a good explanation why though, several customers have requested 6.1 and we can't oblige.

Next will be the 6900 and 6850 I'm sure.

If you guys don't mind I may post here from time to time asking for some input until I get this down to a science.

Re: Un-doing Your Hard Work
 

Flashing erases the entire rom and puts the new one on. There shouldn't be any problems going from 6.1 to 6.0. I do it all the time with no problem.

Re: Un-doing Your Hard Work
 

What are you using as the relocker? I follow the following steps. Relock with ftp://up.ppcgeeks.com/Titan/Users/Im...n_Relocker.exe. Install stock 6.0 rom which also includes a 6.0 radio.
