Hacking the HP rw6828 for use with XDA Atom upgrade - accomplished!

[jiggs]

Although everyone (if not most of us) by now has known that the HP rw6828 is a rebadged XDA ATOM. Apparently, this device, though slower than our current AKU3.3 ROMs seem to have a newer set of device drivers.

These device drivers are essential in the upgrade of our ROMs. Should we wish to port WM6 into our Atom, we will need the most up to date device drivers.

Unfortunately, we couldn't hack the lock on HP Official ROM. So, we though that if some generous soul with access to an HP rw6828 can dump the ROM from the device to an SD Card. This would be a lot of help!!!

Also, if someone knows how to decrypt the official ROM... this would even be better!

I Want Use Atom Rom For My Rx6828, Hp No Rom Update!!!! Angry!!!!!!

this is not possible because HP has placed a lock on you RUU. If we try to trick it to use Atom bootloader, it will check CRC. Are you willing to try??? I will make an ATOM bootloader for your HP. BUT there is a big RISK on this.

give me a couple of days. I need to work on it. The Atom has an extended partition unlike the HP which has NOT. There are applications that need to be migrated to work on your device IF the bootloader that I am going to prepare for you will work.

Just keep posted on this thread. :D

PS: there is already a AKU2.6 for the HP in the official website. You can try that while waiting.

hi all
i can dump Titanium version 2.6aku,let me know.
good work jiggs

[backwards153]

Has this got to testing yet and if so hows it all going. Have problems with my rw6828 not connecting to certain Symbol access points :( seems this is a known issuse between WM5 and Symbol

Wanting to test another image for it to see how i get on.

[tiveyau]

hope my rx6828 can use atom exec rom.....

if can use atom life wm6 is bonus!!!!

wait wait wait

[backwards153]

But waiting takes so long :p

[homer285]

I would say there seems to be some misunderstanding within the HP community.....:D The idea of hacking the HP rom was infact not to benefit any HP user, rather to benefit the Atom with the latest device drivers in hope of using these drivers within the WM6 or Crossbow upgrade. However it seems HP device drivers cannot be used for the Atom (so far anyway) therefore I seriously doubt any cooked or custom rom for HP, unless jiggs can somehow swing it almost blindfolded as he doesnt use the HP.:D

What is RUU?

Since HP rw6828 and Atom is identical in hardware, is it possible to erase the whole rw6828 ROM and replace it with Atom ROM? What's preventing it? Anyway to hack this protection?

RUU- Rom Upgrade Utility

The bootloaders for Atom and HP is not identical. You need the Upgrade/Update Utility to put the ROM into your device. BUT, the RUU in hp checks each file component (radio, ROM, bootloader update, etc.) prior to flashing it to the device. Unlike the Atom DSUU, which checks only the filename and flashes it to the device.

To hack it is to unsign it. Well, someone has to do it. I can't.

another way to get HP's firmwire is dumping whole ROM using pmemdump from itsutils

Adding on. Correct me if I'm wrong. Basically HP hardware allows for ROM flashing same like any other manufactured PPC phone. The hardware won't check if the ROM is from HP or not. Only the software that flash the ROM into the hardware checks the ROM details. So to say, if this RUU can be hacked not to checks the ROM details, basically it's easy to flash the rw6828 hardware with ATOM ROM. Is my statement correct?

Cheers!

Thanks for the clarification. That lead me to another question. I recalled in the past, iPAQ hx4700 got a hacked RUU that allows it to use cooked WM5 ROM. Can that RUU be used here? What's the different? Is HP RUU universal, means usable on HTC and Quanta designed phone?

I am afraid this is not the case. Different devices locate the stuff differently.

I only found this between XDA Atom / Atom Pure / Atom Exec making it possible to flash their ROMs interchangeably.

In most cases, RUU is device specific.

Hi,
I found a tool called Universal BootLoader, on the internet (http://forum.brighthand.com/showthread.php?t=243857) . It's supposed to be able to flash ANY valid rom to ANY hp pda.
Can it be used to flash your modified rom?
If you need somebody for tests, i could flash my device for the good of the world :P

Could you explain, why do you have to modify the bootloader of the atom if these are the same (re-baged) devices?

Thanks for the answers.

PS. I have a rw6815, not 6828.

[DJKai]

Wow good find! That's really interesting, hope this will help the genius's out there to crack this thing.

The identical twin is 6828 in hardware only. BUT different Disk-On-Chip (doc) format!

I don't think it is IDENTICAL to O2 Atom. I did flash ATOM ROM to the 6828 once. I lost the cursor after flash. Maybe they are using different "pen" driver.

OK, so how big is the possibility of bricking my 6815 if I try to flash Atom wm5 AKU 3.3 Final or WM6?

Anyone done it yet?

Huball, did you try the official update from HP dated July 24, 2007 for the rw6815?
Did it do any good?

[huball]

Thanks, Tonio, but I already have that rom installed. Nothing new really. Only some bug fixes (which i didn't experience). No speedup.

[Evilandi666]

are there some news? anyone tried the universal bootloader?

I know a old method for HW6515 from HP. When the Update Process begins, you change the files, and it flashes any firmware on your ppc.

Perhaps this works on rw6815 too? When you also use universal bootloader to get a Atom bootloader into it.

[me101]

Does that RUU you've posted still require the ROM to be encrypted before flashing it to a device?

[drphil]

just the thread i'm looking for. I have a HP rw 6828...
Any body successful in decryption so far?

I don't think decrypting the ROM is the problem, re-encrypting it for the RUU to accept it is.

Apparently, some guy on a chinese forum has WM6 working on an iPAQ rw6828. And from what i can gather, he uses a modified RUU to flash it, but i can't be sure. (mainly because i can't read chinese ;)) I'm hoping someone with knowledge of ROM cooking could translate this if it actually works.

yes. they hacked the rom already, but what they did is extract the rom from ATOM, and use the RUU for 6828,
before flash the rom, delete eboot.nb0 after open the RUU program, the reason for delete that file is, eboot.nb0 same as the bios in Computer, if we don't flash the "bios", 6828 won't dead during flashing.

after "diskimage_ver.nb0" rom flash into 6828, error box appear about "eboot.nb0" not found, that normal, coz we deleted the file.
and that's the end of flashing

translated from chinese hacked rom process

according from the author, the hack rom isn't perfect yet ,
1. touchpad/keyboard "driver" is different, so there may cause error sometimes
2. hang up phone method, press 2 times"hang up" button , because for Actual ATOM machine, dial and hangup are the same button.
3. wifi function, author still working on it. wifi won't work for the 1st/3rd/5th/...reboot and so on

I managed to flash my Hp rw6828 with a Hp 6815 using the patched HPRUU above.
Can this be used to flash my 6828 with Atom WM6 rom? Come on Jiggs, give us HP users some joy :)

I was under the impression that the main ROM file to be flashed to a HP device had to be encrypted before the RUU would allow it, but i guess not. :confused:

And if 'eboot.nb0' is like the device's BIOS? then what happens when you flash a ROM without it? Does it just use the current one or something?

nothing effect flash wm6 without flash eboot.nb0. if flash ATOM's eboot.nb0 into 6828 machine accidentlly, 6828 may not work anymore.

apologize for my wrong explaination. for the eboot.nb0 thing not the bios, wht i meant was "BIOS firmware"

signed. not encrypted. nobody tried the unsigned nbo until now, so we didn't know before.

[tjlabais]

This is correct. The easiest way to solve this is to use the Atom Kitchen, and change the whole of OEM section. use the one from the original hprw6828.


2. hang up phone method, press 2 times"hang up" button , because for Actual ATOM machine, dial and hangup are the same button.


Now, this is something new. we do have two buttons for dial and hangup. we call it send and end buttons.

3. wifi function, author still working on it. wifi won't work for the 1st/3rd/5th/...reboot and so on

same as number 1.
