How to go back to original ROM? - G1 Q&A, Help & Troubleshooting

I have G1 on custom ROM WG Built Y-2.6.
How to flash beack original ROM?
Thanks.

What's your SPL, and Radio? If your 2708+ with the new SPL. I don't think you could flash the original 1.6 ROM. But if your not, just search the Form's for Android 1.6 for HTC Dream or T-Mobile G1. Then flash it like any other ROM.

thanks for response.
radio is 0-1.22.12.29
HSPL 10.95.3000
is it possible to flash original rom?

From what I know yes.
Sent from my HTC Dream using XDA App

I need full instruction to downgrade. Cannot find any on forum.

Find unrooting guides. They often put you back to stock.
Oversimplified instructions:
1. Flash the stock .nbh file in hboot
Done

How to flash an extracted SPL?

Hey Guys,
sorry, I´m searching the whole time after how to flash just an spl, for an extracting I used the NBH util.
My plan:
1) I want to flash my O2 branded Diamond, without flashing a hardSPL.
2) As I understood, it´s possible just to extract an SPL from the newest HTC rom, and flashing this with DiamondCustomRUU in the first step.
3) After this I should have the possibility to flash a full HTC Rom?
Are there any misunderstandings? because I can´t flash the extracted SPL with DiamondCustomRUU.exe.
What did I wrong, and what should I do?
Cheers, Chris
No one any idea???????????????????????
it might be possible to do this!
but you have to be careful not to get device ID/version different on both the OS or the SPL!
but why not just put hard spl and then revert back to stock SPL when you want to at a later stage! all versions of the stock SPL are availble on the rom developement forum

Rooting a HTC Dream without applying another ROM

I have a South African HTC Dream and did some research on this forum about rooting. I am more than happy with the phone's current ROM with the exception that it does not support WPA-Enterprise Wifi - in order for me to configure this, I would need to root the phone and will then be able to adjust wpa_supplicant.conf.
In all the tutorials I would have to downgrade the firmware (I have not been able to do this with any of the guides supplied - either normal RC7 downgrade, 1-click or Goldcard) in order to root the phone.
Is there any way I can root the phone without having to flash another ROM (i.e. retain the current HTC ROM and make adjustments to wpa_supplicant.conf)? Most ROMs provided are not based on HTC build, and I would loose ActiveSync. AFAIK there is no ROM available which provides ActiveSync AND HTC Mail.
My current phone info:

There are HTC based ROMs. The ROM from the Rogers Dream has exchange support, but before you flash the ROM you must flash the new radio then the SPL.

Thanks - I replaced my phone with another one (FW 1.1) and was able to flash. I installed Touchdown to overcome the Exchange problems - not ideal, but best choice now.

You're on 1.1?! I would strongly recommend flashing a Cyanogen ROM to get you back to 1.5.
I did update to latest Cyanogen rom. One question: I rooted the phone and am on latest Cyanogen. Only (minor) issue I have is that before the Cyanogen splash-screen comes on, I still see my mobile providers boot-logo (for about 10 seconds until the splash screen comes) - is there any way to change this?
I tried fastboot flash splash1, but get an error. As part of my rooting I did not flash SPL (i.e. HardSPL) but have cm-recovery - should I update SPL and if so which one (also, what is the risk of bricking?).
If replace SPL, do I need to update the radio again or reflesh Cyanogen?
As far as I know you wouldn't need to flash either again, HardSPL is known to be safe on all phones I believe. The only problems I've heard are with Haykuro's SPL. If you haven't flashed a new SPL that could be the issue, what is the error your getting when trying to change the splash?

It should be safe as long as it doesn't not require a specific radio. I have never heard of the radio version you have, but that's probably because you don't have a t-mobile G1. What carrier is it on? If it's unlocked, what was the original carrier? (the ones displayed on the boot screen).
I think Josh is right that it's safe for all Dream's, so you probably could go ahead and flash it, I'm not 100% sure. Just a quick not about flash SPL's and radios on cm-recovery, you have to physically press alt-s then home+back to reboot. Don't touch the trackball. That's only for SPLs and radios.
The hard spl is great, but if u want to run hero u will nees to flash haykuros spl. If u do flash haykuros spl make sure u flash the new radio image FIRST! OR U WILL BRICK! Have fun flashing away
Thanks. I applied SPL from here: http://forum.xda-developers.com/showthread.php?t=548924
And then fastboot worked: /fastboot-mac flash splash1 DOWNGRADE-SD/Boot_images/android.rgb565
Upgraded to latest Cyanogen 4.0.4 and have now an awesome phone - thanks to everyone for the help on this forum!

I had flashed ota-radio-2_22_19_26I (not sure what it was before). I did roughly document my steps on my blog if you are interested.

thanks. after seeing the radio you said you originally had in the first post i remembered that rogers has a radio that starts with a 3(then i searched and they are the same radio), then when i tried to download the root rogers package from that thread it kept timing out the download, so i was just curious as to radio you used. according to all the rogers root thread you have to flash the 1.33.2005 spl first before you can actually root, so basically i was trying to figure out if devices with that radio are immune to the bricking without 2.22.19.26I radio.

Flashing Back to Stock ROM

can anyone give me a step by step on how to flash my ROM back to STOCK?
if you want it for warranty reasons then you will need to flash the SPL also to stock. you can just download the latest ROM from HTC website and flash it. it will give you the stock ROM on the existing SPL.
End of the post http://forum.xda-developers.com/showpost.php?p=2710548&postcount=1.
Remember you will also need to go back to stock spl if for warranty purposes.

nevermind what i said there, for sum reason it works again now
I've kinda got thesame question. I flashed a stock rom (latest EU rom from HTC site), then stock SPL (1.14) and then the stock rom again. Is this enough to be able to claim warranty without HTC finding out about custom roms/boatloaders?
Thanks

That depends. What was your original rom and spl? Are you entitled (via location) to use the new EU rom, eg if you live in America then this may not be acceptable to HTC.
When you boot up the new rom, are the screen colours ok as this will tell you if you have the right spl for your rom? If you have the latest EU rom, I doubt that 1.14 spl would be the right one, but it could be I guess. With the stock rom, you should also get the stock radio. So provided you have the stock rom available to your area, with the correct matching spl and the radio, there is no way to tell of your exploits
Thanks for your reply
The problem is that the screen of my device won't turn on anymore (Device powers on, I can connect with activesync, digitizer works fine) so i have no way of checking if I have the right SPL or not...
I also have no idea what my stock rom/spl/radio version was.. I live in the Netherlands, and through the official HTC site i flashed the latest rom, which included a radio (a radio version was part of the filename). What I'm trying to find out is:
Could 1.14 have been my stock SPL, or was that version never used on any Dutch Blackstone?
If the spl doesn't match the rom (wrong colours) that isn't much of a problem; I can tell them I tried to update my rom because I thought maybe my screen would work again after I installed the latest ROM... But if I have a SPL that was never even used I don't think they will buy that
According to the wiki there are 2 Dutch roms - one would require a 1.14.0000 spl and the other a 1.54.0000 spl. So I guess either of those would do.
When you flashed the rom from the website, where you still using hspl or uspl? Depending on the rom you flashed you will need to flash the matching spl. Do you have the full notation/naming of the rom you flashed. This should give an indication of which spl you will need.
As much as I appreciate ClydeB1 for assisting you, I fail to see a reason for this thread. A thread already exists for flashing advice, i.e. the dummies guide. Also the HardSPL thread exists and has advice on how to flash back to stock. So depending on your query post in either of these.
The initial query and reason this thread was created has been answered, so no need for this thread to remain open. Thread closed

Downgrade SPL and to Stock to return to Orange

Hi, I'm due to return my Touch HD back to Orange for a swap for a replacement handset, but I would like to make sure I return it back with the original Stock ROM and SPL.
If I switch on my phone with the vol key pressed, it shows that I have:
SPL-1.56.OliNex
And I am currently using the latest MaryOne ROM.
I have downloaded: RUU_BlackStone_Orange_UK_1.14.405.3_Radio_52.49a.25.26_1.09.25.14_Ship which I believe was the original Stock ROM for my phone. It appears that this ROM is the older 1.14 version.
Before flashing my device with this ROM, do I need to downgrade my SPL first? Or is there a way to make the phone use the Stock SPL? (The reason I ask this is because I remember reading the "dummies guide" and it said that in order to use the newer 1.56+ ROM's I had to upgrade the SPL, so my guess is I may need to downgrade now to install a 1.14 ROM?)
Could anyone clarify for me?
Thanks,
WizzKidd

You are correct, if you are using a rom based on 1.14 you need to match the SPL or you'll get screen issues etc. You can either use HSPL 1.14 or return stock 1.14 SPL. All info can be found in this thread including how to return to stock rom & SPL (bottom of first post - section called 'How to reflash Stock/Shipped SPL - STEP BY STEP - FOR WARRANTY REASONS ONLY!')

Help!!

I just rooted my phone. Baseband Version 62.33.20.08H_1.22.12.29

After rooting my i tried fastbooting by holding camera and all i can i see is
HSPL10.95.3000
CPLD-4
RADIO-1.22.12.29
then below it is Seria10
Please I want to install Gingerbread and am having difficulty finding my way from here. I need help urgently.. Thanks
sounds like all you did was downgrade your phone, you still need to flash a custom recovery via telnet, then update radio then spl. if you want gingerbread then you will have to update your radio and spl one more time
google search "cyanogen g1 root wiki" follow the steps after downgrade (radio and danger spl, no need to flash a rom yet)
then dearch the developers section for ezterrys thread on the 2708+ update, here you will upgrade radio and spl one more time
now find the gingerbread rom you want
flash it from recovery
be very careful to read through and understand what you are doing, a brick is easy if your careless when flashing firmware

For easier installation of recovery ,just download ROM MANAGER from googleplay ,end via instal clockwork recovery or for best work RA recovery .
Then you can easily change radio and SPL via recovery ,and instal cyanogen rom ,or or whatever you want.
!!!Just be very careful when changing radio end SPL ,read what first must flashing radio or SPL !!!
One mistake end you phone is bricked!
Sory for my bad englich,and hapy flashing:good:

Thanks so much..am on it.. i went through a post about adb fastbooting process downloaded the files etc using the cmd commands given to me.. I hope am on the right part.
I did the custom flash recovery via telnet immediately i downgraded my G1. should i do it again before updating the radio and spl?
If you have amonra now (or clockwork recovery) then you don't need to reflash it. Just boot I to recovery (hold home while powering on) from here is where you will be changing you radio and SPL
