How to go from RC33 from RC29 manually without root? - G1 Android Development

How to downgrade from Rc33
Ok...I updated to RC33. Didn't know before I updated that I wouldn't be able to go from RC33 to root. So now I need to downgrade.
Can anyone help me downgrade from RC33 to RC29? Or maybe even RC33 to RC30? I searched and couldn't find anything on this but did see someone post that JF walked someone thru it recently....how ever I can not find it.
Any help would be greatly appreciated.

I been in that thread....it's instructions to downgrade from RC30....not RC33.
And I have been going backwards in that thread from the latest posts for about 10 pages now and see nothing about downgrading from RC33.

Doesn't matter what rom you have installed as of now.
You need to follow the instructions and then pick which rom betters you.
Or even try going straight to 30 by renaming it, update, and install it in recovery mode.

Ok....I missed one small word....RC30 and above...
Thanks...in the process of trying to gain root now...

To make it clear for me, is the old downgrading process with a new german RC33 G1 still possible or will it fail because of an new SPL?

i don't really understand your problem. you want to downgrade because you don't have root anymore?
if so, it's a bit strange because i have root access on RC33 Oo

Think he means he upgraded to OTA RC33. Anyway like the previous posters have already indicated, the NBH file downgrades OTA RC33 as well.

ah i see, my mistake.

Hey guys I have two quick questions:
1. I have an OTA rc33 (stock) update on my phone I just received today, in order to root my g1, I will need to downgrade to the stock rc29. It's imposible just to get my phone rooted straight from rc33?
2. If the first question is true. After I downgrade and rooted the rc29, can I just download the latest jfv1.41 rc33 (developer version) ? Or I would need to update the rooted rc30 first in order to get the jfv1.41 rc33.
Your kindly help and suggestion are greatly appreciated.

Correct you need to downgrade to RC29 first for root.
2. If the first question is true. After I downgrade and rooted the rc29, can I just download the latest jfv1.41 rc33 (developer version) ? Or I would need to update the rooted rc30 first in order to get the jfv1.41 rc33.
For RC29 you can install JF's Modded version of RC33
Your kindly help and suggestion are greatly appreciated.

You're welcome

Just One Question:
Is it still possible to downgrade with an GERMAN G1 with the original Bootloader installed on it, or is the security hole fixed which allows downgrading with the nbh File. Please do someone answer me that question please

I tried root but had problems went back to RC29 stock but now I would like to go to RC33. What do I need to do to manually update?

Links to manually update are here:
http://forum.xda-developers.com/showthread.php?t=479571

i manually installed rc33 ota update and so i decided root my g1 then i get stuck on the colorful boot screen.
as the instructions on downgrading from rc30 i suspect it would be the same on a g1 with rc33.
im not sure if the formatting was done correct but i did the following:
on my eee linux netbook i typed
umnount /dev/sdd1
mkdosfs -F 32 /dev/sdd1
the zip file contained a file named "DREAIMG.nbh" the instructions quoted the file name as "DREAMIMG.nbh" so i tried it with both names and i get the same thing.

Root User on RC33 Firmware1.1

I have by my G1 in Austria at T-Mobile. I´m not shure about RC33 but i have Firmware1.1 BuildNumber123099 and KernelVersion2.6.15-01843-gfea26b0 [email protected] #6!
Now i need help for going Root User. I did all things with Terminal Emulator and Telnet.apk I Have install the Android SDK with emulator and adb. and this all for only one - being a root user on my G1 and nothing runs!!!! I have allso a HTC Kaiser and i flash him with soooo much roms without problems and with big help from xda-developers!
Now i know only here i can find a help for my problem!
Sorry for my english but i am from austria and writing in english is very hard for my!!!
I Think im not the first or the last one with this problem! And all who by the G1 at 2009 have these Firmware. So we have to find a way!!!!! PLEASE.
THX for searching
DirtyJ
I come also from Austria/Carinthia and I ordered my G1 these days. I also hope that we will one day be able to root our German G1 with Firmware 1.1. But the only thing we can do is wait and offer our help to people, who know more of the matter. So lets drink tea and wait.
By the way, where from Austria do you come???
I´m from Salzburgand i dont know "Carinthia" The Problem with the new G1 is that T-Mobile will close the backdoor with the root user and so she installed this new Firmware. I´m so angry because i like the RC30 on my G1 also for wlanrouter on my G1. So i hope we find anyone who can help us!

I'm not sure if the instructions found at the link below, work for downgrading from RC33
http://forum.xda-developers.com/showthread.php?t=442480
They worked for downgrading from RC8 / RC30 to get RC29 and root access.
Out of interest if you use those instructions with RC33 please post your results so others know if it is possible.

I don't get it.. 'root' was patched out RC-30 (ie telnet hack fixed), so why is RC33 different ? I doubt they fixed the bootloader.

I assume the bootloader for RC33 is untouched hence the root exploit via downgrading should work and dirtyjunkie will get the root access he/she requires.

Carinthia is Englisch for Kärnten. I think everyone knows Kärnten, because of our Landeshauptmann Jörg Haider, who died in a car accident.

Thanks for the info andonnguyen, this is good news as it looks as if google/tmobile are not actively trying to prevent people getting root using the downgrade method.
Has any german/austrian user tested the downgrade from RC33 to RC29? It would be great to hear if it worked.
Do I have to wipe it after that?
Can't test it yet, because I have an android dev phone
From what i heard there should be a way to downgrade form this Build (is this Build the same as RC33?) and maybe JF already guided some guy through the entire process... at least i think i heard so
i'd also be happy to try this, but i could not find a Tutorial or anything else yet... I'm also an Austrian User with FW 1.1 and really d'like to get root access

here is a tutorial for downgrading:
http://android-dls.com/wiki/index.php?title=Root_For_RC30
Right, but this tutorial is for downgrading the rc30 and not this "special" european build 123099
European G1 has build 123099, RC33 is 126986.
ok, didn't know that... thanx!

If you mean, if you have the oi language in german or english afterwards: of course it's english after downgrading and aupgrading. You put on english firmware with that method.
If you mean, if the downgrade works with your german build, then try it an tell us. I don'T think, anything severe could happen either it works or it doesn't.

Full Factory Restore G1

Can I (we) get a stickied walk through with file links?
My main goal would be to restore my G1 to be able to receive official OTA updates again.
I'm sure a lot of people would appreciate this. Thanks in advance!
If you did a search there is a thread for this
This post tells you how.
Very simple.
Thanks for the response. Using search I found many posts with similar instructions. What I need to know for sure was if the linked RC29 image is an official release or a tweaked version. Remember my main goal is to be able to receive OTA updates again. No one has officially confirmed receiving an OTA update after going through the downgrade steps. It's just implied that it works.
It would also be interesting to know if it goes from RC29 straight to RC33 or not.
Once again, a sticky would be nice.

Well it is simple...but if you have hard spl, and jf rc33 dont you have to push the official keys so it can work I have searched and looked at many threads. sorry about the noob question. Im sending back my phone so i want to make sure its stock
I followed the steps in the post. My G1 also had Hard SPL and was rooted with JF RC33. I didn't mess with "official keys" as I'm assuming they come with the RC29 image that was linked.
A stock G1 bought from a store receives the update wtihin 3 days so we'll see if this works.
Ok confirmed. 2 days after following the steps mentioned above I received RC33. Full stock factory reset restore with update.

Thank you, Guess ill do the same

Ok i just got the G1 yesterday

and i made it have root so i downgraded to RC29 from stock RC33 and now i upgraded to RC33jesusfreke version
but it seems to freeze alot
how do i revert back to original RC33?
if you just downgrade again and leave it, it should (after a little bit) automatically offer you the ota update. it's done this for me after downgrading (though that was from rc7 to rc8 in the uk rather than rc29)
thanks for responding..
so i should put the RC29 back on and wait for it to ask to upgrade?
and is this RC29 the one to use?

I would like to downgrade

to the official RC33 rom. I have had some probelms with jf 1.42 and cupcake. So i just want to go back to what i had. I searched already. I would just like an Update.zip file
The fastest way is just to use the same DREAIMG.NBH you used in the process to root, then apply an official update.zip. Otherwise get an official update.zip and use a signing tool (e.g. signapk) to sign it with the test keys.
This is what I found
**Didnt my link didnt work, not signed. something I have no idea how to do
jashsu thanks worked great!!! thanks man

Ok so I have rc29. I thought it would just ask me if I wanted to upgrade but it hasn't all day. I'm guessing its not an original file. Do you knoww where I can get the original signed file?
Found it!! Thanks for the start
