how can i install an old ROM ?

i am using currently AKU3.3 jester b1 and want to install JAMin's old ROM but the flasher is giving an error and asking to use a newer version of nbf file.
is there a way to install an old ROM to my device ?

try to cook a rom with the nk.nbf from your "old rom" using this tutorial
http://forum.xda-developers.com/showthread.php?t=271043
this rom will install on spl 2.20 also if it's for spl 2.15
when you tried installing your "old rom" it stops at 95% right?
i had the same problem with my german rom and after using this tutorial i can now use the spl 2.15 rom with my spl 2.20 prophet
good luck

this can brick my phone as it is vey risky.
is there a simple way just to flash my phone to an old ROM i mean from 2.20.7.34 to 2.13.9.23 ?

If you had read the post of risidero carefully you would know that it could NOT brick your phone
it modifies your rom so it doesnt contain any IPL nor SPL data. they are staying untouched
the only risk is a non booting ROM which you can simply flash againt when going to bootloader (hold camera button while soft reset)
risidoro said:
By following this tutorial, you're removing both the bootloaders (IPL and SPL) from a rom of your choice. This means that, if you don't make errors while 'cooking' the rom, you cannot completely destroy (brick) your phone. Sure, you could end up with a non-booting rom but, as long as you can get to the three colors screen (the bootloader screen) you'll always be able to install a different (or your previous) working rom.
On the other hand, messing with IPL and SPL (i.e. installing a rom containing IPL and SPL in a CID locked device) is EXTREMELY DANGEROUS and MUST be avoided in most cases!!!
Installing a 2.xx rom without messing with your phone's IPL and SPL is exactly what this tutorial tries to explain.

Install rom from bootloader

How to install new rom when I have only bootloader, mtty 4.12(it's black magic for me) and SD card (2gb). Could You help me?? I need step by step solution.

I have a very similar problem! I built a rom and flashed it using the Nordic ROM as my base image. Unfortunately something didnt quite work right and now all i get when i turn the phone on is the splash screen then nothing...
I can however go into the bootloader, but cant connect using MTTY??? I do have the ability to flash a rom from there using the rom utility, but as its the real SPL i cant flash a rom with only an OS.nb inside. Because i have previously flashed a rom with a different CID i can no longer flash an official HTC ROM.
Is it possible to re-sign an official HTC rom with a ModelID of: VOX010100 and a CID of: 11111111?
Please Help!!
Thanks,

Iceberg if your phone is CID unlocked have you tried to flash my rom from the bootloader, it should work. I've done it a hundred of times.
EDIT : Oooops, I didn't see you changed the CID. Same answer than the one I made to Luniople then, I don't know . You will have to wait for someone more experienced...
Luniople : Sorry I don't know how to flash a rom from sd card. I have nevere tried, but there should be some guides floating around on the forum.

Ehhh....
Problem is done. I give my phone to servis and i have to pay them some cash. He told me that it takes him about 6 hours but i will have a working mobile again

Questions about IPL/SPL and hardspl

Hi,
My old Dopod 818 originally showed the following when booting:
IPL 1.00
SPL 2.15.0000
GSM 02.19.21
OS 2.15.13.27
I used "Prophet Upgrade 2.6 - bikertibi" to upgrade it to WM6.1. I selected HardSPL in that program, and flashed it. This worked fine (scary moment
However, when I boot it now, it STILL shows the exact same IPL, SPL and GSM versions. Only the OS version has changed.
My question: is this normal? I thought the hardspl would change the IPL or SPL versions on the phone?
Is it possible or usefull to upgrade IPL/SPL also?
Second question: if I want to re-flash it again to another 6.5 ROM, can I just use this utility again, without hardspl selected, and without first downgrading back to WM5?
Thanks a lot...

Yup, it's normal because cooked roms don't include ipl/spl (prophet has 2 version : G3 and G4) and radio ... you wouldn't want to brick your device if flashing wrong ipl/spl would you?
However, it is recommended to install HardSPL so that if anything happen during flashing, you can recover the device via entering bootloader mode and only select your device version (G3 or G4) without selecting HardSPL.
ps : your device is G3 because it ends with 0000 .. read the wiki. TQ

Thanks for your reply. So I guess there is no need for me to upgrade IPL, SPL or radio.
How do I know if hardspl is installed?
And if I want to re-flash it again to another 6.5 ROM, can I just use this utility again, without hardspl selected, and without first downgrading back to WM5?
PS. I know my device is a G3, since I already flashed it (see above)
Thanks again.

HardSPL have number like this 2.G3.4PDA (for G3) or 2.G4.4PDA (for G4)... if you haven't HardSPL your device, you need to have HardSPL ticked before flashing. And if anything happen during flashing, your hope is to flash NVID flash.
If your device already HardSPL, you can just redo the flashing. No need to flash NVID unless HardSPL gets overwritten by stock ROM.
Hope this helps.
ps : lucky you .. G3 has more storage memory than G4 ... mine is G4 ...

So if hardspl is present, I should see something like SPL = 2.G3.4PDA at the bootscreen? This is not the case, I still see SPL 2.15.0000 like it did before the flashing. So I guess I don't have hardspl? But how can that be? I click on hardspl in the upgrade tool, and it didn't give an error message... Or do I need to add extra SPL files for this?
It's still unclear to me if I have hardspl installed or not :-( If it's "no", how could I have installed a cooked rom??? If it's "yes", how come I still see SPL 2.15.0000 at the boot screen?
Any help is appreciated!

From what I understand, bikertibi upgrade tools suppose to hardSPL the device but sometimes it seems to just load SoftSPL to the device so that it would temporarily make the device SuperCID? (will experimenting on this) Only SuperCID device can accept any rom. That's why if anything happen during the flashing, your device can only be recovered either by flashing specific CID (t-mobile/cingular/etc) rom or NVID (no specific vendor) rom if it doesn't HardSPLed. It will either reject the flashing process and the device will stuck in bootloader mode.
Since your device still shows SPL 2.15.0000 the answer is no, your device is not HardSPL. Cooked rom was flash successfully because SoftSPL in bikertibi 'tricked' the RUU to be SuperCID temporarily during flashing so it can finish writing a custom rom.
HardSPL for G3 can be download here : http://forum.xda-developers.com/showthread.php?t=353547
To flash a HardSPL, the device needs activesync/wmdc connection to load a special SoftSPL into the device before it can overwrite the stock SPL.
ps : I recommend you learn how to create SDcard dump if you don't want to HardSPL your device. This is because other than flashing stock ROM/NVID, your device can still be recovered using SDcard backup (it will overwrite everything including ipl/spl/os)
EDIT : Flashed my device to IPL/SPL 2.20.0001. bikertibi HardSPL ticked during flashing only send SoftSPL. Flashing was successful. Still need to flash HardSPL 2.G4.4PDA again after phone boots up normally to make it 'immune' from bricking

aze2learn,
Thank you very much for your help.
Indeed, after using the Prophet upgrade tools and activating "hardspl", hardspl was still not on the phone (so it must have used softspl). I installed it manually via the link you provided, and the SPL value changed! After that, I upgraded it to bikertibi's rom.
Very happy with the result.
Thanks again, I will also try the SDcard dump later.

Issue fastbooting Danger SPL

So I have my hboot.img in the same folder as fastboot. I CD to that directory. I "fastboot devices" to see that my phones attached. I type:
fastboot flash hboot hboot.img
and I get the following error:
sending 'hboot' <512KB>.... OKAY
writing 'hboot' ... FAILED <remote: partition doesnt exist>
Any suggestions? I assume it's something silly I'm just missing (I hope)...

I started on the rogers dream where everyone installed the danger spl as the rooting process.. so I'm a bit less than used to other spls.
However can you tell us the version of your current spl (and radio in case we can't solve fastboot)
Thanks.

SPL is EngBootloader_v2
Radio is U_2.22.23.02
I could flash it via recovery no problem, but in light of recent revelations about the boot modes and bricking (and "borking") I don't want to break my g1 before I can afford my Nexus
Any advice would be GREATLY appreciated.
EDIT: BTW, I can issue all the commands I tried (reboot, reboot-fastboot, etc) successfully, just not finding the hboot partition. Saw that I'm not the only one with this issue over on forum.cyanogenmod.com/index.php?/topic/2734-partition-does-not-exist/

Anybody think maybe the problem is with the Engineering SPL? More specifically HBOOT-0.95.3000? That is the SPL that I have and I'm experiencing the same error. Maybe we need the HardSPL to fastboot a SPL? Just thinking out loud...

Meh...I just said eff it and flashed it via Amon recovery. It ain't bricked...so thats good.

No .. well in theory anyway hardspl is the eng spl..
The EngBootloader_v2 SPL is not nearly as nice to developers as any of the sapphire ones.. We have no hboot/spl flash that I can find.. It also dosn't appear to be S-OFF.. a problem if we wish to run an unsigned nbh (maybe hard spl can do that)
I think the best option is for me to return to defanging a sapphire SPL to prevent "boot mode 3" thus hopefully allow you to recover if you flash something out of order..

yes for now that is the way.. just make sure you see a 2x radio in the fastboot screen before going to recovery and flashing..
(ie. if you have a 1x radio.. flash the 2x radio.. reboot to fastboot verify *in* fastboot it is now 2x.. and then and only then think about flashing the danger spl)

Guess thats what I'll probably do too. What about fastbooting an update.zip file with the spl file in it? I'm pretty sure you can do that.

HTC G1 Heeelp!

Hello! I own a rooted HTC G1, with Radio-2.22.28.25_S (s-on) and hboot0013. I flashed many hboots and many roms, but none of them was good enough for me, so I decided to downgrade my phone to 1.6 firmware, and when I tryed to flash dreaimg.nbh it gave me an cid error, so I flashed Hard SPL because it said that it does not require cid, and signature. The result was that the sd card can not be mounted, either in recovery (RA) either in the rom, so I can not flash a different radio or update anything else. Now I have instaled on my phone a creepy rom named froyo on saphire or something like that. I also have tryed to unluck my bootloader with a tool downloaded from htcdev, but it gives me the following error on the log: (the command: fastboot -s HT848GZ14667 getvar mainver) getvar:mainver FAILED (status read failed (Too many links)). So I can not change anything on my damned phone. What do you think, can I do something with it?
