Flashing a stock ROM first? - Touch Pro2, Tilt 2 Windows Mobile General

I've seen people say to flash a stock ROM before flashing a cooked one - why? Surely all the data from the last ROM is overwritten by the cooked ROM anyway, isn't it?

I'm not sure about the TP2 but on the hermes it was always recommended for going from an extended storage rom to a normal rom. Might have just carried over since then.

Doesn't make a difference, its a myth. The flash chip gets rewritten.

Not a myth, at least to some devices like the diamond, HD and the HD2 where members who decide to skip this step are finding themselves with very unstable devices that often turn off or restart on there own.
Flashing a stock rom or using the mtty tool erasers any artifacts that can be left behind when flashing cooked roms.
Flashing Procedures I use:
• flash stock rom or mtty tool found in sig.
• flash cooked rom
• hard reset twice
Never had any issues from automatic resetting of any kind!

ive been flashing since the wizard, and probably after 20 phones ive never flashed stock rom first. i actually stop hard resetting to.

As mentioned, some devices are more prone to it perhaps. There are a lot of threads that speak to members dealing with device resetting and other glitches and the remedy recommended is always the same.
For me, it's just habit now....

Only do this as a last ditch effort. Say u flash a custom rom, hard reset as u should, then configure the rom. But u seem to be getting odd screen freezes and problems that only u seem to get and not anyone else for that particular rom. U go into the thread of the rom asking and everyone says its just u. Well at this point u would flash stock rom, hard reset, flash same custom rom, hard reset, now the custom rom works perfect! Why? How th hell should i know? I just know what works!

I think that flashing a whole stock ROM each time is a bit over the top. If you want to be on the safe side, then do a hard reset on your old ROM, then flash the new ROM, then hard reset again. That should do as much as flashing the stock ROM would do.

I think main the benefit is because the CustomRUU doesn't perform a Hard Reset after flashing, where as the Stock RUU does.
Some people prefer to do a "task 29" nand format. Unless you've been flashing dodgy ROMs that go outside of where they are meant to then I think you'll be OK.

DaveShaw is the man so take his advice.
I have flashed over 40 ROMs (all from XDA or HTC) on my TP2 and I never flash back to stock. I have had no issues. I also did the same with my Tilt1.

Resetting and turned into a hard reset?

any time now on any rom, i'll soft reset my phone and all of a sudden it goes to the windows mobile start screen with the screen calibration.. (basically a hard reset to a clean os)

I am sure I have advised this when you wrote on one of the threads. Try flashing a shipped rom first, it is in my 4shared, doesn't matter if you have AT&T 8525 or not as it works for my jasjam. Flashing too many radios may kill your phone. So ... flash that and then flash the one you want ..
I have not in my time flashing my phone and my customer's phone that a soft reset causes a hard reset after following the doctors instructions
i will try that but what does the regular att rom have that customs dont to stop this from occuring

As I mentioned no issues for me yet touch wood/knock on wood as your part of the world probably accustom to.
ok so far so good, no more hard resets but i just wondered what the original att stripped rom is actually doing to stop this from happening and how much more to reflashing the roms before it happens again..
it has something to do with the big storage/non big storage flashings etc and that shipped rom sorta resets it all to an acceptable state to the phone's brain so to speak .. the doc's never wrong

In a normal rom, the flash rom is split into two pices, ext rom and storage rom.
In a bigstorage rom, this boundery is removed.
Now, over time, this causes instability in the way windows access and manages the rom, leading to data loss (random hard resets).
Flashing a OEM rom with a OS partition and a Ext rom parition acts as a spring clean on the memmory layout, thus, stability.
As with windows, most things are solved by formating your HDD and starting again, its the same kinda thing!
Great.. Thanks guys, im back to normal now with no hard resetting.

Problems with Radio flashing via SD-card

So I have problem, I updated rom from sd card, it worked nicely, but when I try to update Radio, sd flashing app freezes in 'Update in Progress' state, in about 10 percents.
It takes about 1/2 hour to flsh radio rom. DON'T interrupt the flash or you will get a brick...
I will try it to leave flashing for several hours even status is not moving..

I think what he is saying is if this happened the first time you tried flashing the radio you might have a brick at this point..
Best idea would be to try and flash shipped stock rom, you might get lucky and fluke it... WM06 from the carrier you originally had would be ok too as the radio might be able to be fixed but don't count on it...
Theres been limited success...
Good luck...
I managed to flash rom called Manilla 2d, sometimes I have no gsm message sometimes not, I tried to use mtty to access radioloader but there are always error message. It is possible to check physically(by opening case) if the radio stack is destroyed?
I installed WM5 via sd-card with radio rom, it was going really slowly, I thought it freezed again, but then finally it started moving, and finished instalation. Even now I cannot remember how many procedures I have done many different roms, radios, mtty procedures........ and finally radio works, wm works
Cool, glad to hear it.
Now would be a good time to flash Hard SPL V7. It can help you out of perilous situations. Please remember though, even though it worked this time round, it may not again. I personally DON'T flash the radio rom unless I REALLY have to. Either use cooked roms or edit the originals using Rom Koch. You can remove the rdio part and flash just the os.
Cheers...

Great advice there. Find a radio you like and stick with that. With the Hermes being end of line there, you won't see many if any new Radio's available. In my experience the best ones to date are either 1.47 or the 1.56 radio.

Warranty vs modified ROMs

Hello all,
I've just heard of HTC not providing warranty to devices with altered Roms.
Considering this is true, has the Touch Diamond 2 a reset button to place the original factory Rom before sending the device to the manufacturer?
I'm planning on buying one, this is why i'm asking.
Thank you,
-Moving Thread-
1) this does not belong in the android development
2) the reset button reboots the phone.
Rebooting the phone will only restart whatever ROM is on the device. You can use a key combo to force a ROM reflash that will return your phone to its original configuration. There is also a program called Clear Storage on these phones that will do the same thing.

Wrong.... using the "key combination" will NOT reflash back your original rom.. all that does is hard reset the phone to the original settings of the custom rom you put on the phone.
If you have done any reading about flashing roms you'll see its a 2 parter. The first is the Hard SPL and the second is flashing the custom rom itself. If you plan on sending a phone back in for warranty purposes and have a custom rom on then you need to do two things. Flash back to the stock rom which you can download in the roms section and then you need to respl your phone to whatever version of spl your phone had. I believe there are three different ones to choose from.
That way when you send it in they cant tell that you had a custom rom on and that you dinked with the phone in any way.
So in short.... doing a hard reset will NOT just go back to your original rom.
Do some reading in the rom section, specifically the Hardspl thread and within the first page everything is explained in details on how to hardspl the phone and REspl the phone back.
good luck
Didn't mean to get your dander up, but if you reread my post I said nothing about it reflashing to the stock ROM. I said it will reflash to the original configuration, meaning whatever ROM is currently on the device will be reset and lose any customizations or add-ons. A soft reset will not accomplish this. Sorry I wasn't more specific.
Oh no worries Miami... Keep in mind the guy has 1 post... He could have been around for ages and know all about flashing roms and what not but its pretty easy to assume he doesn't know much about it with only one post. If I was confused by what you said I can only imagine what he thought. "oh once I flash a custom rom I just have to do a hard reset and it goes back to the way it was when I got it"
Just covering the bases here right

ROMS conflicting and a clean start

So, I flashed my frist rom back in April. I tried out the Energy Rom. Last night I tried out the Core Cell Evo Rom. This Rom started to give me trouble so I flashed to the current energy rom. I'm still new to this, so I think I may have made some kind of mistake that I'm not aware of.
I noticed that when I flashed to the new energy rom, the splash screen for the cell rom came up. Now whenever I try to change the date and time on my phone, it kinda locks up. I think it still functions, but because the screen is frozen I can't see what to press so I end up doing a restart. Does anyone know how I can remove all the remnants of the cell rom? I thought when you flash a new rom, it's supposded to completely get rid of the old rom?
First run TASK29, then flash preffered ROM, after that do HARD RESET, and then it must be OK
Some ROMs include a new splash screen, and some don't. The EnergyROM series doesn't include a splash screen, so that's why you can still see the Core splash screen.
You can find utilities to replace this if you search for "splash screen".
Task29 won't affect this (i.e. it doesn't touch the splash screen, nor the radio either), but it does a good job at wiping the ROM area itself.
If the problem still happens after a task29 and a flash (i.e. the lockups), then you should post about this in the thread relevant to the ROM you're running.
Thanks for the info guys. I'm at work but I'll try out the task29 thing when I get home. I didn't post this in the energy rom thread because I didn't want to seem like I was directing my problem at that rom until I had a good idea of what was going on. If the problems still persist, then that's where my next post will be.
You can always reflash a stock ROM. That will give you the original spash screen back and then you can flash the custom ROM again.
Well, it wasn't the splash screen that I was worried about. Seeing the splash screen made me think that the core cell rom was conflicting with the energy rom. After hearing what steviewevie had to say on the subject, I know otherwise. I'll also install a custom splash screen later now that I know that can be done to.
You can go here for the steps to change the splash screen its actually pretty easy and fun.
http://forum.xda-developers.com/showthread.php?t=576703
Ok, I ran Task29 and I've installed the stock rom. Do I need to do another HardSPL before I can flash a new rom?
No you only need to perform the hardspl once which you have already done so from now on when changing roms just make sure to task 29 then flash new rom and thats it

Oh? I didn't use the stock rom that was put up on this site. I actually downloaded the Tilt 2 rom from the HTC site. So I thought that would have made some kind of difference.

HardSPL was designed to stay on the phone, even if you flash stock ROMs. You have to specifically run the relocker utility (from the HardSPL thread) if you want to go back to the stock SPL (e.g. for warranty return).

I'm moving your thread to General. This has nothing to do with ROM development. Custom ROM usage yes, but not Development.

HTC Desire - New to android modding - help needed

Hey everyone,
I'm really new to android modding, and don't know much about all this. I'm good at modding but never been on android before. I went through the stickies and full desire guide etc threads, but its really getting confusing for me.
I've come to know some things: (correct if wrong)
1) You have some custom ROMs which you can flash after rooting the phone.
2) Most ROMs have pretty much everything working, but some things don't work on some ROMs (like camera for some)
3) Rooting voids warranty.
Seeing the vast amount of ROMs in the development section, I'm confused which one to look for. Can anyone suggest me which would be the best (stable and everything working) ROM for me? I basically need APP2SD or APP2SD+ (NOT the froyo one because its useless, I'm talking about the custom one) and minor tweaks like changing the homescreen etc.
Which would be the best suited ROM for above description? Basically, what criteria decide which ROM to put on the phone?
@Moderators, sorry if its the same old story. I'm really confused and so HAD to make a thread.
Hi and welcome. A couple of points I can help you with:
There are loads of roms to choose from, I am using this rom atm:
http://forum.xda-developers.com/showthread.php?t=768703
Everything on this particular rom works fine and is very fast and stable. I generally find if roms have several revisions then are are generally very good. i.e. are having continuous support and developement.
As for rooting voiding warranty? Well this is no longer an issue as rooting can easily be reversed )
Hope this helps

You do indeed need to Root the device before flashing, the only ROM that don't have 'things working' is the Desire HD ROM. I am not sure if that has been fixed or not yet though. All the other AOSP and Sense based Desire ROMs have everything working just fine. Rooting will void your warranty but it's super easy to reverse so there is nothing to worry about.
The most popular ROMs by far seem to be the AOSP (Android Open Source Project) ROMs (Non-Sense ROMs), all of them will have APP2SD built into them, the Sense ROMs also have APP2SD built into them.
LeeDrOiD is by far the most popular Sense based ROM, RCMixHD is the Desire HD based ROM, which I think still doesn't have the camera working.
And by far the most popular Desire ROM overall is the ASOP Cyanogen based DeFrost.
To get the most out of APP2SD you will need to download ROM Manager and create an EXT3 partition on your SD card so the ROM will place all of the Froyo compatable apps into the partion and not your internal memory.
Being brand new to the desire, I've flashed every Rom available in the last 2 weeks.
Leedroid is a very good sense Rom. I prefer having a Rom with sense right now because this is my first HTC.
Right now I'm running the Aurax sense Rom, solely because it has its own setCPU built in.
The hd roms didn't impress me that much, not yet at least, with a little more time they will be awesome though.
The MIUI roms are also amazingly pretty, if you don't mind the iPhone feel. My only problem with it though, and I've been told this hardly happens, my battery life was pathetic.
At the end of the day though, apart from the hardware, it is android and all the available apps that make our phone so great.
All the custom roms do add a lot of speed to the phone though, you have to do a quadrant after you flash so that you can see how awesome the Rom makes your phone run. They also add additional functionality compared to the stock Rom.
Honestly, I can't see why anyone would keep any Android device stock when there are such amazing roms around. At the end of the day its all down to your own preferences and what functions you like. You'll love any Rom you flash.

Thanks for such amazing replies. Meanwhile, I've also been through many ROMs and their descriptions. The terminologies are kinda new for me, but I can understand many things now....
The only thing I care about right now is App2SD because I found FroYo's move to SD doesn't help much. Also second thing is that I'm not having MY desire yet, its my friend's device m gonna try out everything on! So I'd be taking some extra care!
One big relief is that rooting is reversible. That'd be cool.
What are the odds of bricking your phone while flashing or applying mods?

It is honestly impossible to brick a desire. I bricked my MOTO backflip, there was no coming back from that. With the desire I flashed something that didn't work, but pressing volume down and power gets you right into the hbooot menu, from there just mount as usb and copy over a new Rom to flash.
The one thing you need to remember, when flashing new roms the first boot takes a while, never pull the battery thinking there's nothing happening, that will destroy your phone and there's no coming back from that.
Before every Rom you flash make sure to do a factory reset in the recovery menu, that ensures that the new Rom will work to its full capability and minimizes the chances of experiencing problems.

You can brick your device flashing Radios, but you can always send it back to HTC, pay them an extortionate amount and they will revive it for you. But overall, the chances are slim to none in my experience.
Just make sure, after rooting, you make a Nandroid backup of the OS. Then you can do whatever you like to the phone and it will be reversable.
I keep a Nandroid of my DeFrost ROM, and one of my PaysROM, and I have one of my MoDaCo R8, you can switch between them just using Recovery, as the mood takes you, absolutely everything will be exactly as it was everytime you load the backup back onto the phone, I just wipe the cache, Dalvik Cache, factory reset the ROM then reinstall whichever ROM I want to use (DeFrost, PaysROM etc etc) from the SD card and then backup from the Nandroid.
Depending on the age of your desire, you shouldn't need to flash a radio though. I've never needed to flash a radio, but that's because my desire came with the latest radio, thankfully it still has the amoled screen.
If you do need to replace the radio and somehow brick it, if its still under warranty HTC will replace it for you because there is no way that they can prove you bricked the device.

Wow that means you install a ROM, make settings you want, put in your data (phonebook etc) and then take a full backup. Switching between them is as easy as restoring a backup!
Is that right?
Initially, I'd be trying out ROMs, and would stick to the one which suits me best. I just can't wait before my desire arrives this monthend!!

It saves everything, app data, messages, settings, the lot. Although when switching ROMs I still factory reset, wipe the caches and reinstall the ROM I want to use before loading the backup of that specific ROM. I am not sure things will go so smoothly if you just reload the backups without factory resetting and reinstalling the ROM first, but it won't hurt to try.
