New Custom Roms - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

Hi
Just wondering if anyone has made any new custom roms. I have looked so far as I can in the forums and I cant see a cooked rom from the kitchen for the hermes.
Would be nice to see if there is one superb one out there that would replace my rubbish t-mobile one!
Thanks
Phill

Right now everyone is using the 1.35 south africa released HTC rom with the latest imate 1.20 radio.
You first need to SIM/CID unlock your phone with pofs hacked radio rom (which you might need the slightly illegal bootleg bootloader downgrade from any version to 1.04 to accomplish)
then after that you can throw up 1.35 on your device, and use the aforementioned bootloader downgrade util to get down to BL1.04 to put the 1.20 radio rom only upgrade on.
Theres no cooked roms or kitchen ATM because the devices are locked to official roms only. Once someone figures out how to get around that its open season!

---

Unfortunately, due to encryption of the ROM, there are no custom "cooked" roms as of right now.

---

I am thinking of buying a Hermes however what is the latest AKU avaliable?

Hermes custom ROM cooking
All shipped Hermes bootloaders enforce signature checking on NBH files against an HTC private key, this is what is preventing the development of custom AKU3.x cooked ROMs on Hermes (and all other new HTC devices).
The SPL can be hacked to avoid this, but it will require some months of research... if anyone here has knowledge with disassemblers / debuggers such as IDA Pro or radare, embedded device bootloaders and ARM/Thumb assembly and is willing to help with this, feel free to contact me on this matter and we can work together
I can't give a real estimation of when this will be possible, because it depends on a lot of factors, but I'm sure we'll be able to do it in the future...
Anyway, I see a lot of people willing to have an AKU3.5 on its hermes, but haven't seen anyone willing to cook it himself on this community yet ... so we need people willing to cook Hermes ROMs first, otherwise the effort put in hacking the SPL is not worth it.

Do You Have Any Links To How To Cook Your Own Hermes ROM Pof? I Would Be Interested In Trying To Cook My Own ROM And If There Was A Turorial/Guide Telling People How To Do It I'm Sure That Many People Would Start Cooking Their Own ROM's.

The tutorial does not exist because no one has done it yet, so if you investigate how to do it the first, you can do the tutorial.
A good starting point is having experience with ROM cooking on previous HTC devices, I don't want to discourage newbies in that area but it really helps a lot.
For the Hermes one must first learn how to extract ROM parts from NBH file, this is explained here.
Then one needs to be able to modify OS.nb to add/delete files and modules on it, I have no idea on how to do this on hermes "OS.nb" files... on previous devices one could convert NBF to NBA and use mamaich imgfs tools, but I don't know how to convert Hermes OS.nb into NBA to do it.... so this point should be where people willing to cook ROMs should have to start researching.
I myself never cooked a ROM for any previous device, but have used cooked ROMs in my old BlueAngel and Universal, and more-or-less understand how the cooking process works because I've read the relevant threads on this matter here... I am also not going to loose my time cooking ROMs for the Hermes at this point, because I believe it's more important to loose it in research to provide a way to flash this cooked ROMs once they exist, but we'll get things done faster if we work in parallel, that's why I ask the community to start the cooking research now, even we don't have a real solution to flash the cooked ROMs yet.

Once we have chance to USE cooked ROMs we will start cooking, right away... No point in starting to cook it if there is nobody who can eat it...

Once you have the chance to flash unsigned code, you'll need 3 months of research to be able to cook a ROM because nobody has investigated on the OS rom layout of the hermes... you'll only be able to flash your splash screen if you stay there sitting and waiting for someone else to do it, we're a community of developers, and what I am asking is to work in PARALLEL.

OK, let's make it easy: Imagine hacking the SPL to flash unsigned code takes 3 months, and producing a flashable OS.nb with AKU 3.5 takes another 3 months.
"blue pill") 3 months to hack SPL + 3 months to produce cooked OS.nb == 6 Months to have your cooked AKU 3.5 on Hermes.
"red pill") 3 months a group of people researching on method to hack SPL and another group of people investigating how to produce cooked OS.nb == 3 months in total to have your AKU 3.5 on Hermes.
In the Matrix, which pill would you take, the red or the blue?

i would like a lethal dose red pills please

---

pof, is it just me or does it seem like no one else is interested? Seems like lots of people are interested in flashing a cooked rom, but doesnt seem like many people want to help get there

@shogunmark: yes
To make things easier I've just published a tool to extract the contents of NBH files, so people does not have to mess with perl:
NBHextract: Extract contents from NBH files
OS.nb can't be converted to a valid imgfs_raw_data.bin using mamaich prepare_imgfs.exe, I still don't know why. Theoretically it should be the same as a decoded nbf (or nba) file, but imgfs tools don't like hermes OS.nb
It would be great if anyone can have a look at it and point us in the right direction...

---

Oh pof and shogunmark,
you can belive, if I would have the knowledge I woul help you.
It's a nice tool to extract the .NBH and a good start to make things like romcooking. Thanks.

---

hi POF,
I've tried to run your tool but don't work.please let the world know about this software in order to reduce working time (from 3 months to 1,I hope)..
thanksss

Weird, I was using HTC 1.35 rom to do the tests, and was unable to get a imgfs_raw_data.bin bigger than 7Mb.
I have just tried with HTC 1.18 rom, and I could dump OS.nb without problems
Code:
C:\imgfs_tools>prepare_imgfs.exe OS.nb -acer
Searching for IMGFS start... Found at 00659000
Dumping IMGFS ...
Done!
C:\mgfs_tools>dir imgfs*
14/01/2007 09:11 53.215.232 imgfs_raw_data.bin
14/01/2007 09:09 0 imgfs_removed_data.bin
C:\imgfs_tools>viewimgfs.exe imgfs_raw_data.bin
Probably OS.nb has a different layout on newer Hermes ROMs... will have to investigate that!

Hi
The way, I've testet the tool is the following:
1.unzip the NBHextract folder to c:
2. put the .NBH you want to extract in that folder.
3. go to the commad-console and switch to folder "NBHextract"
4. type"NBHextract.exe HERMING.nbh -v" now the tool extracts the content.
It's easy .

It's the same problem with the german O2 Update

thank you scorpio16v

Ok 2 Questions.
1.
I Tried Running The Program On An NBH File I Downloaded But I Got An Error.
C:\>NBHextract.exe test.nbh -v
The system cannot execute the specified program.

2.
Most/All Of The Updates I Download Come In .exe Format, How Do I Get An NBH File From The Exe.
Finally. With You Being Able To Extract The OS.nb File Pof Does That Mean In Theory We Can Cook Roms From The Older (1.18) Roms?
Cheers
