CE and Radio ROM update only, no extended ROM, how please?

I want to keep all the O2 stuffs intact, is it possible to update only the CE and Radio ROM but not the extended ROM? I know the procedures I think, and I just need to delete ms_.nbf before running BaUpgradeUt? Will my O2 extended ROM stays intact this way?
How much better is 1.06.2 Radio ROM better than 1.02? Is it worth the update?
And after the update, I should just restore DATA but not full restore right?? Also, do I have to disable ActiveSyn before the update? If so, how?
Sorry about so many questions

Think ur ext rom will be blank this way

My answer to your question would be
Unhide the extened rom as is
unlock extenedrom as is now
make a copy of it as in on your desktop
do the normal upgrade
unlock/unhide the new extended rom
delete the content
copy from the destop your old extenedrom
lock/hide the exteneded rom again
do a cold reset.
this will boot the device, reinstall the os and radio and install the old extenedrom.
Do I think that that is a good idea, NO!! but that is what you want to do.
You need to undersatnd that some of the stuff on extened rom is for the new upgrade such as the patches.
So ... not that you asked ... I think what you want to do is swap only some of the files. but do you know which ones?
Read the bit on unllocking the Imate extenede rom
Read the bit about changing boot imaages.
Think about what you realy wont to do and have fun.

but it's not true. I've done that and your Extended ROM is not deleted
so:
1. You chose the ROM you want to use it (and you use xda3nbftool.exe if the ROM comes from another operator than yours)
2. Before launching the ROM installer "BaUpgradeUt.exe", you remove the Extended ROM package which is call "ms_.nbf"
and you update your ROM normally
Only the CE ROM and Radio will be upgraded. Your Blue Angel will keep your old Extended ROM.
And remember: If the ROM you have chosen comes in a package like BA_WWE_BelDT_12200_557_10602_SHIP.exe, you can open the ifile with WinRAR to extract its contents.
Simple solutions for a simple world!

True, only Qestion I have is why did I not Know that before?
Yup its simple and it works.
Now a real qestion for you based on you own knowleage.
Is there any way to add a Romkitchen Exteneded rom to the upgrade?
We seem to have know tools for this er2003edit does not work for me on the blueangle.
I have not been able to find any way of extracting splash screens but am able to replacing then (which is great but I dont have the original splashes)

Things are not only you know, your ways are not always the best.

General questions regarding the updgrading of ROMs

Ok, I will preface this by saying I am a veteran of Wallaby upgrading. I had one of those for a long time and probably used two dozen different ROMs on it. I cooked my own, and I nearly paper-weighted it or the radio stack a gillion times. I can definitely figure things out for myself.
That said, there is very little useful information as to how the upgrade process works with the Blue Angel. For those of us in the US on Cingular with the SX66, we have no update out at all, and we're very much stuck.
Things I don't get:
1. Extended ROM. Actually, I know what it is. What I don't know is, because it exists, does that mean that the base ROM is completely carrier independant? In other words, if I take an Imate or Qtek ROM and install that, but keep my carrier's Ext ROM, will things be the same? (assuming the same language, WWE) Are the base ROMs ever updated, or is it the extended ROM?
2. Where are the tools? The wiki is very out of date, and I don't know what the proper tools are to use. Do I write to an SD card, or do it over USB?
3. Is the radio stack updated by a first run program on the device itself, or is that done from the computer? Do RSU updates come with base ROM updates?
4. There seem to be new security measures taken to hinder our tinkering with the ROMs. How safe is it to change things (for purposes of "going back")? I dunno what else to ask about this...
Feel free to answer any or all of these questions, and for the love of God, don't tell me to search--I did.

Well said, but good luck getting answer around here.

I'll give it a try, but some answer could be plainly wrong, since I don't have a blueangel.
Blueangel and himalaya upgrading are very similar so this page is not so outdated:
http://wiki.xda-developers.com/index.php?pagename=HimalayaRomkitchen
But the mayor problem is indeed the new encryption method used :
ER2003edit or xda3nbftools don't support it (yet)
thus :
* you can't change the countrycode/language anymore
* you can't change the extended rom ms_.nbf
but the extenderomunlocker still works for Blueangel, although you have to use the Blueangel version, so after an upgrade, you can still manipulate the extended rom on your pda & hard reset.
BlueAngel Extended Rom unlocker
Blue Angel Romkitchen thread
thread about the new encryption
Answers :
1: You probably will get a country code error if you try a nk.nbf from another provider. Base roms and radio rom do get upgrades, but I don't know which one are already available for blueAngel. Base and Radio are carrier independant.
2 : Tools : see links above
3 : see himalayaRomkitchen
4 : You can make a backup on SD, but can't seem to find a link right now.

SIM Unlock help...

Hi all,
I had an O2 XDA Stellar which I believe is the HTC TYTN II. However, this phone was stolen a couple of weeks back. I purchased a second hand one today which is sim locked to the orange network. I managed to break the lock by following the instructions on this link http://forum.xda-developers.com/showthread.php?t=433835. I followed the instructions word for word till step 5.
The problem is now though it accepts the SIM and I can dial out, I don't have any audio on the calls So I can call and my phone also rings when I receive a call but I can't hear the caller nor can I be heard at the other end
Also, I hate the orange rom (and I used to complain about the O2 rom) and I wish to use the default HTC WM 6.1 professional upgrade the problem again is that it asks for a serial number and my serial number starts with DCOxxxxxxxxxxx and it says that this is not a valid serial number
What do I do now? Has my phone become a brick Please do help I can't bear the thought of having one stolen and the other toasted by me
All help will be greatly appreciated

Did you actually read anything or did you just start hacking away ? I will cut and paste a few items out of that thread, so that you don't have to actually read it .
PLEASE READ THE *FAQ* BEFORE FLASHING OR ASKING QUESTIONS!!!
* IF YOU DONT NEED TO FLASH A NEW ROM THEN PROCEED TO STEP 6 TO PUT YOUR DESIRED RADIO BACK*
7. After I flash a Rom I dont have any sound in calls and the camera is black
The Radio has to match the version of Rom you flash i.e. WM6.1, an incorrect Radio will give sound and camera problems. Read The Ultimate Radio Thread to find a Radio that matches the Rom there are lots to try on there if one doesnt work then try another.
3. What are the different types of Unlock?[/B] (answer by DaveShaw)
The three stages of unlock are:
SIM: Allows you to use SIM's from another carrier. Can be done using codes or unlocker programs on xda-devs.
Security: Allows you to flash radios from another device - It does other stuff, but this is all the casual user will use it for
CID: CID unlocking is an old concept, nowadays you flash HardSPL instead. This lets you flash any ROM, Splash or Radio (depending on sec unlock) to your device. N.B. the CID is the carrier ID (e.g. HTC__001). The stock SPL's only let you flash ROM's that match the CID in the ROM image with the CID on your device.
Obviously you did not unlock your phone if a serial number is needed to flash a new rom. I would re read everything and do it again

Thanks for the reply

I've been through this link as well and I was contemplating installing the latest version of the HTC WM6.1 ROMS (version 3.34.721.2, radio version 1.70.19.09) available at http://wiki.xda-developers.com/index.php?pagename=Kaiser_ROMs However I was not sure if this would be ok and (at the risk of sounding extremely dumb) I was not sure what WWE stood for

I maintained the default that was given by the unlocker for the CID (I think all zeros). Do I have to change this as per the ROM image? I don't mind re-doing this again it's a relief that my device isn't busted

No your phone isn't busted. Go into bootloader and check what it says next to spl, if you followed Mark's steps, it should say 3.29 Hard. If that is what it says ,then you can flash any Kaiser rom you want. If it doesn't then start over again.
WWE stands for World Wide English and those roms are all in English. That rom you picked will be fine, if you do not wish to explore the fine world of custom roms ? Maybe later.
You only have to CID unlock once by following the steps, not at every rom flash.
No sound means wrong radio, 6.0 roms need 6.0 radios and 6.1 roms need 6.1 radios. If the rom has a radio in it already then flash away.

Thanks Denco Flashed the ones I mentioned and it works perfect. Can't believe I actually have a working device Thanks for all your help, really great.
Now to sync my data to my new (second hand) htc and I'm good to go

Another question, the device works fine, however since it is a HK rom, it seems to have localised to HK. I've changed this as much as possible to UK. However, I'm wondering if this will affect anything else? For example the gps? Is there any quicker way to configure this globally so all settings use UK instead of HK?

Why didn't you flash the latest UK ROM.
Use this code: HT750GB02264 to download from HTC's site.

Once you are unlocked and HardSpl'd you can flash any rom you want. Pick a UK one another WWE rom or a custom rom. Test a bunch until you have one you like. Your only restriction is it has to be a Kaiser rom. And with all the Kaiser roms available, it is not a restriction at all.

Wow, thanks for that, I was looking for a valid serial through which I can download from the htc uk site One question I had is do I install the radio which I download from htc? Or do I keep the one I have already flashed? The one I have flashed yesterday seems to be a later version than what I've downloaded from htc

1. I keep hearing on this forum about Hard SPL, I'm not sure what this is used for or why it is required but I followed the instructions and it seems I had installed JumpSPL1.56-KAIS.exe. Now, since then I had flashed the rom, so do I need to reinstall this again? Is there some other one I should be using? I come across different versions on some threads. Also, how can I check the version of HardSPL I have?
2. When I view the memory (under settings) it shows me Storage and Program. However, I can't seem to see any storage area in file explorer. I know in my old xda 2i, there used to be a separate storage area. The reason is because some of the apps I install are quite bulky for example lexisgoo english dictionary (the dictionary files themselves are about 18mb) and this fills up the main memory. How can I install this in the storage memory? (not storage card since I sometimes swap storage cards)
Sorry lot of questions I know, but I'm a newbie and all help will be greatly appreciated

The UK downloaded ROM will install the radio too.
I would do a bit of testing with your current set-up, then flash the UK ROM.
Test the new UK ROM & radio & then reflash the radio only if you want (do some searching on Radio versions)
Newer versions are not always best, chasing the latest builds normally bites you in the ass at the end of the day.
Check HardSPL by going into bootloader:
* Using a stylus, press and hold the soft reset button at the bottom of the phone along with the camera button
* Release both buttons once the bootloader screen appears
* Exit bootloader by pressing soft reset button
Once you have installed HardSPL thats it, job done (you installed it during unlocking)
What you see in file explorer regarding storage is correct: 128MB RAM for running software ect & 256MB ROM for storing your programs ect (WM2003SE was different)
ROM can be increased by using one of the cooked lite ROMs if storage space is a concern.

Will do, the HK version seems very stable, the only thing that bothers me is the region settings. Anyway, I think I'll give the UK Rom a go and if that works well I'll stick with it

I've attached a screenshot of my memory screen. The bit that puzzles me is that the storage area apparently has a lot more storage but I do not have an option to install all my applications on that area or atleast the bulky ones. I don't think I need a lite one since I do have 112MB free in the storage area which is more than sufficient for all the apps I usually install. Can you advise how I can install apps to the storage area as well?
Lastly, I was wondering if it is possible for me install my apps on the rom and then kind of take an image of my setup and flash the rom with this setup. That way when I do a hard reset, all my apps are installed again. Which will save me the trouble I know sprite backup does something like this but I'd prefer if it was in the rom
Thanks for all your help, it has given me a lot of confidence in these matters. Something I probably wouldn't have attempted

I agree 101% and it appears fewer resources are put into ironing out bugs in the WM 6.1 ROMs than the WM 6.0 ones. I replied to fmervin's post in the ROM forums along these lines.

If all is running OK I would stick with your current HardSPL.
When installing your applications choose the option of installing to "Device"
You could install all your apps into a ROM, this would be cooking a ROM & is a complex process.
I would suggest a backup via Sprite or SPB. I use SPB v2.0 build3065 & it works well for me, preference of backup software is a bit of a Marmite scenario, you either love it or hate it.

Lastly, I was wondering if it is possible for me install my apps on the rom and then kind of take an image of my setup and flash the rom with this setup.

You can't do that, it is flash memory. It's not like you can partition the hard drive.
But this is the easiest way to get your Apps and settings back after a flash.
Try this Sashimi Auto installer by a former XDA member. It is a nice little program that installs all your apps after a flash

Hey Denco..Than'x for considering my thread & giving out suggestion towards the link to check the info. But i m really nt that techy afterall so i can burn a ROM on my Tytn II. Even though i tried to burn a RUU rom that supports TyTN II ..Its just gets disconnected from USB mode..So i was looking forward to start it initially with some comparatively easier to install .cab files..Can't these RUU files be transformed into .cab files or maybe some other version of Manila 3D cab file that is completely fixed...I seriously have done a lot of research upon this but nothing looks like working. So please if you have some links to .cab files that can give a better & different look to my Kaiser running Windows 6.1...It'l be a great help !!
Than'x & regards in advance

I think you need to decide what it is that you want to accomplish. Unless you cook your own rom, there is no way to add apps to the rom ( so that they will remain after a hard reset) Your rom is wyour phone's base operating system, it contains your OS (WM 6.1 ) and can only be replaced after completely erasing and replacing all files from the previous rom.
If it is a new rom you want, pick a rom that interests you and follow these instructions verbatim .
http://forum.xda-developers.com/showthread.php?t=433835
Your phone will go to the bootloader screen ( three color) and it will disconnect from usb during the process, but be patient until the end. When it says it takes ten minutes, it takes ten minutes. Leave the room if you have to , to keep from getting impatient.
If you just want to keep your OEM WM 6.1 and keep it simple, but change the look of your phone try this,
http://www.htcwiki.com/page/Manila+2D+and+M2D+Themes
This will change the look and feel of your phone with uninstallable .cab files and will not affect the rom or brick your phone by accident.

how to to repartition the rom

Hi,
I'm trying to upgrade my radio rom. At first everything seems fine but after the upgrade process is at about 30%, I get error no. 114. I think that maybe a part of my rom is broken, so I'd like to change the allocation of my roms. I'd like to have the extented rom part as new radio rom and vice versa.
Is that possible? If yes, how is it done?
thx for your help
PECK

sorry to disappoint you, but no, that is not possible.
start the other way around, do not try to bypass a problem by creating a new one, try solving the problem first. why would the radio rom abort in the middle of the upgrade process?
- do you use the right upgrade tools?
- do you use the right radio rom?
- did you take care of everything else there is about upgrading a rom (bootloader, active sync kill...)?
- are you able to flash another os rom?
...whatever comes to mind when flashing roms, because this problem will not be any different after all.

@ chef_tony:
I've no problem with upgrading the OS or the extented rom! thats why i think that maybe the flash chip is broken!
I tried many different upgrading tools, even one of yours!
I don't know the current language id of my device! Originally it was a german XDA III! How can I check the current language id and how can I change it? is it possible that I have this problem because of a wrong language id?
thx in advance
PECK

i would guess it couldn't have anything to do with the country id, error 114 is radio rom update error.
btw, you get to see the inofficial country id everytime you soft reset the device, and in the bottom right corner it says something like WWE, or GER, for instance. or, when you connect the device and run getdevicedata.exe from the ruu folder, which is done before the upgrade, to show you the "from:" and "to:" numbers.
but: i just got another idea.
do you actually take out the sim card, before trying to upgrade the radio?
is your device sim unlocked?
have you played around with different bluetooth stacks?
have you performed a hard reset before trying to upgrade the radio?
have you tried upgrading the radio from the stock o2 rom wm2003?
ok, that was more than one idea, and downgrading seems like a lot of work, but it is worth a shot. if you spend days flashing (or trying to) over and over again anyways, you might as well try that, would mean 2 extra upgrading sessions, but what is that, like an hour?
oh, and what radio rom does the device have now, stock? or is it a newer one already?
and why do you think you need to upgrade the radio rom anyways? phone not working, maybe the problems lie deeper and that could be why the upgrade process can't work in the first place!
"don't confuse an original symptom with the sickness from the drugs we gave him" as dr. house, would say

hi,
the device is unlocked! there was no sim card inserted during the upgrade; i just tryed with one but I get the same error at 32% progress...
it doesn't work with the original rom, also!
it would be fine if the stock rom was installed, but unfortunately i don't have installed any radio rom whatsoever!
windows mobile device information says that i don't have a radio rom and no protocol installed!

oh, for pete's sake, i'm sorry.
when i asked you about the sim card being inserted, i thought of taking the card out, if you hadn't done before, should have written that. many people have problems when having a sim card or sd card inserted, i didn't want to suggest to put one in! that can never do good, either nothing happens or it gets worse, i really shouldn't have forgotten that.
it doesn't work with the original rom, also!
Click to expand...
Click to collapse
yeah, but does the stock rom itself work? i mean, the stock rom is a so called baked rom, meaning it contains a rom, an extrom and a radio rom, while the cooked roms here only contain the actual rom, so the os. i mean, you could try and extract the radio from the stock rom and try and flash that. it would give you a radio back! or if that doesn't work either, try flashing the entire stock rom, if that works without problems and then you'd have a radio, it means that your issue is too strange to think about, but still you can delete the extrom again and flash another rom without harming the original radio.
wouldn't that be a step forward?
btw. what radio rom are you trying to flash?
if it is just one, you try over and over, are you absolutely certain, this is for the BA? which version is it? what was the original file name of the exe? where did you get it? have you tried re-downloading it, maybe the file is really broken!

hi,
i tryed many different rom versions, and i'm pretty sure they are for the blueangel!
do you know, where i can get a cooked rom for my xda 3?

first, to be clear about that, as mentioned before, cooked roms consist only of the operating system itself and contain neither a radio rom nor an extrom. so about every rom offered here is a cooked rom. but that won't solve your problem, since, as mentioned, there is no radio included. that is why i suggested for you to try the original radio from the shipped rom, and then the entire shipped rom, to determine, whether the radio rom flashes, when it comes after an nk.nbf rom, which would mean, that from now on, you'd have to "bake" roms yourself, by taking cooked roms and adding the radio, so to not lose it. when you can actually flash wm2003 you can also try flashing other radios with the original BAupgradeut, because in contrast to os roms, there should be no limitations to the radio roms, as far as i know.

Upgrading wizards which are already unlocked

Hi,
Being a newbie into upgrading ROMs, i have a basic quesition.
Do we need HardSPL or SoftSPL even if my phone (a G4 device) is bought with CID already unlocked?
I went through the comprehensive information link
http://wiki.xda-developers.com/index.php?pagename=Wizard Windows Mobile 6 for newbies
but could not get the answer to my question.

If your phone is CID unlocked
To flash cooked ROMs, you need the "Wizard No ID Update Utility"
To flash OEM ROMs, nothing special is required

What exactly is the difference between a cooked rom and a clean rom??

No download luck
I tried downloading the file but the site times out. Any possibility of posting another link?

"Cooked ROM" vs "Clean ROM"
The two are not neccesarily relevant to each other. A ROM determines the behavior of the operating system - what icons you will see, what software is installed, how the touch points are located etc. A "cooked" ROM is simply a ROM that is hand made by an individual (hopefully with experience at these things) as opposed to an "OEM" ROM which is developed by a professional team and made available by a service provider - AT&T, T-Mobile, Vodaphone, for example.
A "Clean" ROM is just a term used to describe a ROM designed without a lot of extra software - just enough to run all the functions of the phone, but not slow it down. Some people want a ROM with games, office apps, weather and on and on; others find that this just clutters up the phone and slows it down, so they prefer a Clean ROM.
