Can I go back?

I looked around and did not see a clear answer to the question of reverting/flashing back to WM5 if desired after flashing one of these WM6 ROMS.
Does anyone know where I can find the answer?
Thanks in advance.

I too have looked around but haven't asked for fear of being flamed. The gurus think that we should be able to pick up on all the lingo and have a clear understanding of what everything means.
I am looking for a way to go back to a shipped ROM from anything after flashing SPL 1.11 in case I need to warranty exchange my Cingular 8525. I have yet to figure out how to do it.

Yes. You can go back to WM5 from WM6. I have done it before with no problems. Your answer is once again yes!
I will not flame you but look harder.

...but just to let You know..
once You go black (2.5 ), You will never go back...

hi there
first of all, I am no expert in the ROM related knowledge, but i did go back to WM5 from WM6 recently. The reason I have gone back to WM5 it is because I am suspecting the Chinese viewer (CE-Star) that i used does not work good in any flavor of WM6, it causes frequent lock-ups in WM6 that makes my phone pretty much unusable.
Besides, i don't mind to share my experience for downgrading to WM5, the following is my up and down sequence.
1. upgrade from Dopod WM5 rom to WM6 cooked rom
2. upgrade to SPL 1.40
3. upgrade radio to 1.38.00.11
4. upgrade radio to 1.40.30.00
5. upgrade to SPL 2.10
6. downgrade SPL from 2.10 to 1.40
7. downgrade from WM5 Rom (It is some sort of HTC Standard WM5 Rom that my friend gave me, and my radio has gone back to 1.38.00.10 as the ROM comes with it.
8. upgrade to SPL 2.10
9. upgrade to Radio 1.40.30.00
Also, you may check out mrvanx's guide for downgrading to WM5 here.

actually... i'm on black 2.5 and thinking of going back... too many apps are wiggin out on wm6

I actually just did it. I was running the latest version of HardSPL, flashed to the new ATT ROM, and then created a updater to flash the SPL to the ATT spl.
Wasn't hard, and only took a few minutes. So, as of right now, my phone is running the new ATT ROM, and if I need to warranty it, I'm all set.

in the wiki it mentions..
If your vendor has released you original rom as a shipped upgrade, you just need to flash it.
If your vendor has not released any ROM upgrade yet, you cannot fall back to original ROM easily. You'll have to reconstruct the ROM out of a dumped ROM.

I'm using 838pro, what about the ROM which available to download from the dopod company website.
does it safe to just flash from it or do I need to repackage the ROM..?
thank you.

if you only want to read chinese, but not input, there is an alternative to it. look for a cab which is named 'sunglobe.ttf register patch'.

Maybe the easiest way
First thing I would want to do is to Flash the unit to what is known as a "Hard SPL". For some reason it makes all the other flash work go a lot more smoothly. You can get instructions and software for that at:
http://www.mrvanx.org/cms/index.php...ask=view&id=40&Itemid=26&limit=1&limitstart=2
Once that is done, and it should take about 5-10 minutes depending upon the speed of your computer and USB connection, you can load whatever OS rom you desire.
You can get a carrier agreeable rom from the Cingular/ATT site:
http://www.htcamerica.net/support/8525/software-downloads.html
Or, and this should work, just link directly to the rob by clicking:
http://www.htcamerica.net/support/d...R_WWE_2.15.502.3_6275_1.40.30.00_108_Ship.exe
This should leave you at the latest and greatest of the WM5 packages from Cingular/ATT, and all should be well. And . . . if it hozes . . . which it should not, you should have no warrantee issues since you were trying to flash the upgrade that THEY were providing you. :-D
Laters,

ROMs from Dopod HK or Singapore are very old ones. The SPL is 1.04. You may not be able to flash backward if you are with HardSPL v7. Also if your radio ROM is newer than 1.27, you may face problem when you flash the original (as it is packed with an old radio rom).
(Please correct me if I am wrong.)
To play safe, follow mrvanx' guide:

After some readings and I have managed to used dutty's tool to recompiled the Dopod's WM5 English rom from the original Dopod shipped rom.
This rom has OS + Extended Rom ONLY.
No IPL, No SPL, No Radio.
I have tested and it works on my Hermes, and Bootloader and Radio stay as is. Please note your result may vary.
Here's the download link
http://rapidshare.com/files/29500131/WM5_Dopod_1.30.707.4__Huchison_3_AU__OS_ExtRom_only.7z
To play safe, I would suggest you to do the following prior flashing the OS rom.
1. Flash boot loader to Hard-SPL-V7
2. Flash your radio rom to 1.38. or 1.40

Flash O2 XDA Diamond? To Remove Branded Rom?

Hi guys ... I will probably be getting a O2 XDA Diamond...
The O2 Diamond has a blue branded Touchflow Gui...
Will there be anyway to install the Original HTC software on it so i have the nice Black Menu?

yep you have to install a hardspl, either olipro's [which i think is unreleased] or the one made by the diamond project team.
then you can flash a new rom.
however, check your rom version in settings->system->device information
if it reads 1.34.831.1
it means you have a new spl that prevents you from flashing hardspl until the experts here create a work-around.
i hope this helps
Rory

On a related note, I was considering getting the O2 XDA Diamond but putting the black TouchFLO 3D on it. However, I've now decided to get a normal HTC Touch Diamond, because I'm lazy and I don't want to flash a new ROM for a number of reasons.

I dont think ill be getting the htc modell becaus i would have to pay much more...
Because of the o2 contract that i have in august i can re new the contract an will get a o2 xda for about 100 euro... so i think ill be sticking to this modell..
Please keep this thread up 2 date guys... Good work so far...

Well I´m pretty new to this. Im gonna get a XDA Diamond too within these weeks. But as mentioned the blue TouchFlow theme from O2 is really ugly in my opinion. So maybe someone can explain me how it is possible to change the ROM to get the original black theme from HTC.
What is necessary for that to work, what changes would that bring to my system (all programs lost?) and what dangers come along with that?
I appreciate your answers. Thanks.

c´mon guys, please give me some information on this.

Ok .
First of all you can take one of two options.
1) Hard SPL the device and flash a new ROM that someone has mirrored here.
Look here for Hard SPL ( Read carefully as not all Diamonds can be Hard SPl'd as yet)
HardSPL Here -> http://forum.xda-developers.com/showthread.php?t=395640
ROM is here -> http://forum.xda-developers.com/showthread.php?t=394985
Hard SPL your device as per the Instructions then run the ROM update that you would have downloaded above . Job Done.
2) Wait until someone removes the 3G Interface from a Diamond (HTC Maila) and then apply that cab to replace your blue one.
Hope this helps
If you read the very first thread in this forum then you would have had an idea on what you was asking.

Thank you very much for your answer. So just to get me right. If i need a german ROM, is there a chance, as far as the new ROM version (probably comming with the german xda) is HardSPL useable, to flash another german HTC ROM on to it (if someone is providing it)?
And the last question, do i loose all my installed or preinstalled apps on my device, such as TOMTOM when i flash a new (other) ROM?

If its an O2 ROM then as you have an O2 device you may not need to Hard SPL but not sure on that one.
As long as you Hard SPL the device then you will be able to flash any ROM that turns up on this forum on your device. Please read the post I pointed out to you, as one of the SPL's shipping on the Diamond will not work and you may brick your device
And the last question, do i loose all my installed or preinstalled apps on my device, such as TOMTOM when i flash a new (other) ROM?
When you flash a device it will set it back to a ROM only . EG all the apps etc you have installed will be gone. TomTom if available on the device ROM will be on it as well (Although I thought O2 pefered Copilot) . If not have a look around the Forums and find a suitable TomTom cab for the device.
Again if you spend some time reading some of the threads on here and within other devices you will start to understand more .

Ok guys so hold us up to date on this.... Im getting my O2 phone in 2 weeks and I think I wont like the blue TF3D.

Ok guys... so is there any new information on getting the branded colour touchflow 3d to the orignial black one? Someone here mentioned doing it without any hardspl stuff via a CAB file or something....
ANy news on this?
Thx Busta

Here in germany it's possible to renew your contract through several online shops. When doing so, you can get any device you want. You usually also get a better deal than renewing through O2. Try if this is possible in your country and get a HTC device!
The only advantage of getting an O2 device is, that you get a refurbished device sent to you in case of a waranty return and don't have to send it in for repair. (At least that's my experience with the hermes aka. XDA Trion I had)

Whats the point of getting a HTC Touch Diamond then? The "fun" begins with cooked ROM flashing and since the Touch Diamond seems to be more and more popular, some very nice ROMs will be out in the near future. Can't wait to see where this is going...

Flashing to another ROM with HArdsSPL wipes out all in your RAM and ROM memory. it over writes al registries.
Also TomTom. A back-up is not advisable as it will not run, or cause bigger problems.

Read and search mate !
I did as i'm a total noob and still managed to install hardspl and the new rom !
Its all here to be found

OK, Noob education thread!!

OK, so I’m going to be getting a UK Orange branded Touch Diamond this week. My aim is to remove the Orange branding in the software and revert it to standard HTC black and white theme. As it would be out of the box if I bought one direct from HTC. I’ve no interest in any tweaks/improvements to the standard ROM (different radio ROMs etc) at the moment, maybe once I’ve managed it once successfully I’ll worry about that! I’ve spent a day or so reading these forums and though it seems complicated to a beginner I think I have it all figured out now! I would appreciate however if someone experienced could cast an eye over what I’m about to do and let me know if I’ve made any errors that could result in me ruining an expensive piece of kit!
My understanding is that there are basically 3 stages to flashing a new ROM onto a Diamond, backing up, loading hardSPL and loading the desired ROM. So my plan is to do the following:
1. Back up all operator settings (WAP, MMS, GPRS etc) or use something like PIM Backup (though I won’t have any data on my Diamond as it will be brand new!)
2. So, first I download the signed version of hardSPL (1.40), from here (http://modmydiamond.info/index.php?option=com_content&task=view&id=12&Itemid=26&limit=1&limitstart=2 ). My understanding is that by using the signed version I’ll reduce to a minimum any chance of buggering up my Diamond and basically it will stop me from doing anything stupid!!
3. Then follow the instructions on that same page, which will install hardSPL.
4. Now find a ROM that I want to load onto the Diamond, from what I can tell this (1.34.831.1 WWE from http://forum.xda-developers.com/showthread.php?t=399680) is the latest HTC released ROM in English (PLEASE correct me if this is wrong!!)
5. Follow the instructions detailed here to install the ROM (http://modmydiamond.info/index.php?option=com_content&task=view&id=12&Itemid=26&limit=1&limitstart=4). As I understand it, when I unzip the ROM that I have downloaded, it includes the 6 files listed on that page, including the ROM update utility.
As I understand it following the instructions on that final page will leave me with a Diamond that is not in any way Orange branded and has the latest official HTC released ROM on it (black and white themed menus etc etc).
So, is everything that I’ve written correct, and if I follow these instructions will I avoid ruining my phone? If I’ve missed anything to check before I start or that I need to do please point me to the thread that explains it so that I can look over it.
Hopefully over time this thread can be a one stop shop for absolute noobs who are unsure of how exactly to go about flashing their device, and in what order to do things!!
Thanks
JP

I'm still a noob, too, but two things you should make sure:
- Have your battery on the phone fully charged
- Disable standby on battery and on AC power in the phone and on your main PC so they don't shut down during the flash process
I just flashed my Diamond successfully today, it's actually quite easy if you get the right steps - and thosee above look just like what I did.
Good luck!

4. Now find a ROM that I want to load onto the Diamond, from what I can tell this (1.34.831.1 WWE from http://forum.xda-developers.com/showthread.php?t=399680) is the latest HTC released ROM in English (PLEASE correct me if this is wrong!!)
Really, that's the first and not recommended.
1.93 is the last, but not very obvious where it is released from.
1.37 is what I know the last official release.

Orange UK ROM is 1.37...
When flashing one for a friend I exprienced issues trying to flash HardSPL with 2 errors but managed it in the end with Olipro HardSPL 1.3 the but Diamond project team 2 rom on, the flashed radio rom back to 05.

How do you tell if it really is stock and uncooked? No idea, but it works very well indeed and is very responsive.
Oh, and the dev hard spl works to flash 1.93; some others I tried didn't. YMMV

Noob Question: HardSPL and ROM

Hi,
I have a CDMA diamond (flashed) but now my friend ask me to flash her GSM diamond for her.
I am fairly familiar with flashing (it's a few clicks after all).
I usually get CDMA stuff from ppc-geeks and i am fully aware that xda-developers are for GSM diamond (that's why i am here).
I have a few questions after reading a few posts and hope someone can fill in the gaps:
1. I am aware that HardSPL which only allows Oilnex signed rom seems to be a better idea. Which version i should try?
2. I am aware that there are many roms out there and each has its own pros and cons. Would anyone name a few that's closest to the stock diamond rom and name a few that's most popular?

The 1.93.olinex is probably the best choice because there are only a handfull of oli signed roms in existence. The non-dev version of hardspl should go the way of the dodo as people seem to rarely use it.

which rom update to get? current version 1.37.707.1 WWE

hi guys
as you can see im a total noob to the forums and to updating ROMs on the diamond
my htc diamond is running rom version
version: 1.37.707.1 WWE
date: 06/10/08
radio version: 1.00.25.03
protocol version: 52.26a.25.09H
i find that phone lags a bit and slows down especially when im unlocking with my password.
it also lags a bit when im activating the keyboard to write a sms..
so i guess i was hoping somebody could guide me in the right direction to get the latest rom update, and how do i do it.
i can see there are some custom roms around...so i have no idea whats the best way to proceed..
ive tried to download the latest rom update from the HTC site but it says that my device is not supported?
i dunno, cause i entered in the serial number located under the battery...
so im hoping somebody here can help me out..
thanks!
subs.

More info...
What's your diamond model number? It's under the battery.
You should look into HardSPL and then check out the official ROM's and Cooked ROM's and make a decision on which one you want to flash your phone with. Read the forum's and how-to's for more info...but first you should work out what version of the diamond you have before you go looking for ROM's...also, always HardSPL before you flash!
Good luck.

under the battery it says
HTC P3700 DIAM100
is that what you are referring to?

i would like to do this rom update on my phone
http://forum.xda-developers.com/showthread.php?t=423418
so from what i understand i first have to install a unsigned hardspl, any recommendations on which version i should use?
1.23
1.24 or
1.34 ?
i was going to use 1.24 only because i saw somebody post saying they used it and had no problems, but if i should use one of the other ones because it will work better then please let me know.
after doing the hardspl install i was going to backup all my contacts and then do the rom update.
am i missing any steps?
do i have to do a radio update before a rom update?

I use HardSPL 1.40 and had no problems so far so I havent updated it to 1.93.
I would recommend one of the new roms 2.03 (official or cooked, it depends on what you'd like ).

Install hardspl 1.40 or 1.93 (I use 1.93, but didn't have problems in the short time I used 1.40) hardspl and then install any rom you like. Just try to read as much as you can because chances are, any question you have, someone else has had it and it's on the board for you to read.

ok cool, i will install hardspl 1.40 and then that rom i mentioned
at the moment i dont have any questions, i will follow that thread that explains how to update roms and hope for the best

if you brick your phone, the only option left is to claim warranty.
And i believe the only step that could possibly brick your phone is flashing HardSPL, right guys?

I was in the same state of anxiety when I did my first ROM flashing. Thankfully it all went smoothly.
My 2 cents :
1, Think about what you are gaining by a ROM upgrade. If your phone is working well out of the box and your routine functions are satisfied, you are well off with you stock ROM. I flashed a couple of ROMs and now I am with my stock and I am perfectly fine.
2, Read this -> http://forum.xda-developers.com/showthread.php?t=416211 and this -> http://www.modmydiamond.info/ And if you understand every single letter of it only proceed.
Happy flashing

thanks for all the help guys, but i decided to flash my htc with the original rom from the htc site.
for the moment it runs like a dream and has fixed all my lag issues.
so im gonna stick with that....for the moment

It's important that you feel comfortable crossing over......but I have to say, when you decide to cross, it's an exhilarating feeling to know that you can select what ever Rom from, what I think are, top notch chiefs here but also the fun continues by selecting which ever Radio.
Many post on here that say, "I bricked my phone," truly didn't brick anything. They just hit a wall so they panic. Hard SPL really does a good job. So the chances of your bricking this device is not as high as some people think..
