eris 2.1 to 1.5 downgrade

my girlfriend hates the OTA 2.1 cause there is so much not working now
so i was wondering if there is way/tutorial to downgrade from the crappy 2.1 OTA back to original 1.5 without rooting
if not what is there a tutorial for rooting then downgrading
Edit:
since i have a moto droid and my girlfriend didnt care much about rooting till now what type of things are diffrent when rooting the eris compared to droid (OCing, roms, themes, nandroid backups, ect.)??

Check out this link to root the eris: http://forum.xda-developers.com/showthread.php?t=647707
I'll post again once I find the 1.5 rom, although I think it may have been removed.

After searching it appears that jcase took the download down at the request of a few users.
So, what I would do is root then flash some of the new roms that have come out. Personally, I'd give either CyanogenEris or Senseless a try because they are AOSP based (like your droid is).
If you are into the Sense scene, I would check out the plethora of roms listed here: http://forum.xda-developers.com/showthread.php?t=649705

so your not able to just downgrade?? cause thats all my girlfriend really wants
and are the 2.1 roms(with sense ui cause for some reason my girlfriend likes it) based off the leaks or the official 2.1 and do they run better then the official 2.1
Edit: that tutorial is for stock 1.5 not 2.1

Downgrade instructions are here http://androidforums.com/all-things...ot-thread-apps-roms-updated-05-06-2010-a.html
Full Downgrade from 2.1root (any) to 1.5 stock - FULLY WORKING
THIS IS NOT FOR LEAK USERS SO DON'T ASK
If it bricks your phone, not my fault (it shouldn't and I hope it doesn't).
Please read and follow the directions included.
unzipme.zip md5sum: 0ed3c91d7574367d65428b3bc230f217

This is fully working, I just did a full reflash to 1.5, including the kernel, the system software, the radio firmware, recovery image and the bootloader.
This must be done from a PC with Fastboot, which comes with windows. Linux/Mac users will have to find it and compile it. You will need to have Amon's recovery image installed to use this downgrade, at the end we will overwrite his image with the stock one.
Inside unzipme.zip are three files
downgrade.zip md5sum: c440c87f1e67f4b62e05da0d255e80e9
-Do not unzip/open/alter this file
--Contains your kernel, radio firmware, and system.
recovery.img md5sum: 71a4b633bdb32de9dcdd8953fef43cdc
--stock recovery image
hboot.nb0 md5sum: 38899da4e5e002e3be22900f5f4eb6f7
--Original bootloader
Step one:
Put hboot.nb0 and recovery.img in the tools dir of your sdk.
Put downgrade.zip on the sdcard of your phone
Step two:
Turn your phone off, then turn it back on holding the power button (red) and send button (green). Once in the boot loader press volume down, then volume up to get to Amon's recovery image. Go to wipe, wipe dalvik cache, and do a factory reset (aka wipe data). Then choose flash zip from sdcard, and flash downgrade.zip. The phone will flash the kernel, and system softare, then ask you to reboot. Let it reboot so it can flash the radio, it will restart back in the recovery image. You can power down your phone now.
At this point if your just wanted 1.5 back, you are done.
If you want the original bootloader and recovery image, (ie 100% stock) continue on.
Step three:
Plug your phone into your PC. Power your phone on using the power button (red) and send button (green). Your phone should now be sitting back at the bootloader screen and say FASTBOOT USB. Now on your PC, go to the sdk tools dir in command line. Issue this commanhttp://www.multiupload.com/6UE7AUN810d
Code:
fastboot flash recovery recovery.img
Let it flash, when done wait a minute (just to make sure).
Then issue this command
Code:
fastboot flash hboot hboot.nb0
Once this is done, wait a minute then pull your battery and restart your phone.
You are now back at factory stock.

Personally I'd stop after step 2 in case you ever want to flash a rom in the future.
Woops, I missed that she's not rooted. You could root it and go back down to 1.5.

In theory you could downgrade using the same methods as going from RUU 1.17-1.16 (since they have the same bootloader version and are both signed), but I don't know that anyone on 2.1 OTA has tried that.
Even if you got it to downgrade she'd be bugged constantly about the OTA (every 2 minutes I believe), which would suck for her. Also it takes up ~100MB of space on her phone too, so I would just go with rooting.

The root process is exactly the same for 2.1 OTA users, but will not work if it's a 2.1 leak.
At this point all the roms are based on 2.1 OTA or another person's 2.1 rom and most of them run better than the 2.1 OTA.
It's really just a trial-and-error process. Some users will swear by one rom and hate another, while others will swear by a different rom.
I'd have her look at all of the roms and pick one based on looks, because it sounds like she won't use most of the advanced features anyways.

yea she doesnt care for the advanced things i have tried to get her to use another home replacement app like helix cause i know sense ui is a resource hog but she likes it too much and doesnt wanna try and get used to something new but i will talk her into rooting and choosing a rom she might like thanks for the help
i had a rom before 2.1 for the droid that didnt block the ota and it was very annoying it varied between 2 minutes to ten minutes

is there an app like rom manager to switch between roms like the droid

I went from 2.1 OTA back down to 1.5 using the RUU MR2 on the computer. Worked like a charm!

HBOOT 1.49.0200 and 2.1 RUU

I just recently rooted my phone with the new methods and also did the bootloader mod as well. My question is what would happen if I flashed the stock RUU of the latest OTA on my phone that has the 1.49.0200 S=OFF bootloader and Amon_RA's recovery installed? I know it would un root the phone but would the custom recovery and engineering bootloader be intact still? Basically what I want to do is have a stock ROM with superuser support. Thats it. OTA notifications would still show up but I would just ignore them. I'm guessing if the recovery and bootloader were not touched by the RUU I would just flash my overclocking-kernel-v3 and EngTools to root though recovery.
Thanks in advanced. You guys are great. Keep up the great work. You have my full support.

If you want a stock ROM with SU just get plain jane. Or install SU by putting the .apk on the phone.

Why not use a rom like Ivan's or Plain Jane?

I have this obsession with having things as close to stock as possible. I would just prefer the "stock" way even with the apps like Amazon MP3 and other stuff still installed. I also just wanted to know what are some limitations of the engineering bootloader like if I did upgrade to a new official OTA in the future.

If you flashed the current RUU it wouldn't mess with hboot so you would be able to flash a recovery and add root to the rom.
And if the update thats coming doesn't mess with hboot you should be able to add root to it later, but we don't know if it will mess with hboot.

It would be very easy to simply keep everything the same in the OTA rom and just add su

also im pretty sure u cant use the RUU if you have the bootloader 1.49.200 because the bootloader on the RUU is 1.49.000 so its lower it wont go.

I'd suggest you actually take a look at the ROMs suggested. They might surprise you how "stock" they are.

I rooted my phone back when I had HBOOT 1.47, and it brought me to 1.49.200 for root, and I flashed the RUU and it brought me back down to 1.49.000.

Help with unrooting

first, yes i know how to search!
i've found out that when you want to unroot your phone you have to do it using ruu's.
how do i know wich Ruu i should use?
when i install the Ruu, is it just like installing a new rom using clockwork?
and when i've installed the Ruu how do i uninstall clockwork and all the other things that comes with the root?
i am currently using the standard 2.1 update 1 rom for wildfire (original rom)

if you plan not to do rooting and flashing anymore, just update to 2.2. Everything will get original, but you will lose the opportunity to root it again. Otherwise, flash a kinda of unroot image, which comes with unrevoked, i didn't hear about it anyway. Try yourself.

To install the RUU, Download it (It will be an EXE File), install HTC Sync on your PC, Connect your device, and, run it. You will lose Clockworkmod and all root associated apps and priveleges when you unroot it.

First check that you can root your phone.
If you already have Froyo installed on your phone then you will have the new Hboot.
If can root use the old unbranded Eclair Ruu from shipped rom's.
It's in the guide (turkeys guide i think) stickyd at the top of the page.

I also want to go back to using stock ROMs. Froyo actually. The only reason I rooted was to gain app2sd facility which was not there in Eclair.
Now that Froyo is out for wildfire spare me the unstable ROMs. I will go for the Stock one.
I have the RUU for my mobile. But When I run it from PC, I get cannot upgrade your phone. I understand this is because I am having a custom recovery (Mine is ClockworkRecovery).
Now can anyone tell how I can get the stock Froyo ?
Do I need to get the stock recovery back ? Is there a bypass for this ?
Or is there a .zip file intead of RUU.exe files for Stock Froyo ?

[Q] Well this work to unroot Rooted Gingerbread 2.3.4??

By my understanding you can't just flash the new gingerbread update 2.3.4 if your rooted and have s-off right?
(unless it's the rooted one which I currently have http://forum.xda-developers.com/showthread.php?t=1175536)
you need to be unrooted with s-on?.. So I'm thinking about unrooting my phone using the automated way
(http://forum.xda-developers.com/showthread.php?t=924923&page=13)
so now my question is it safe to do this with the rom I have? Because I have read forms that once you update to the new ginger bread you cant downgrade? Or that it's just a little more difficult to do right? ( I don't know if has to do anything with the rooted one I have btw) so if I unroot using that method well it root since I'm technically going to downgrade right? Since the unroot instructions says you have to flash the PD15IMG.zip (which I think it would be an older version.) So that being said can I just unroot using that method but instead of using the PD15IMG.zip they give you can I used the new gingerbreed PD15IMG.zip file SO WHEN THE PHONE BOOT UP I WOULD HAVE THE NEW GINGERBREAD UPDATE 2.3.4 well that work?!?!?!
reason for unrooting have bad chip..

this update i think is no different than the full RUU we had before, if you flash this or that RUU, you will goto stock unrooted factory mode, with just one think that may or maynot happen,....
1: for me i still have S-off, so i still do whatever i like.
2: for many they turned to S-on and now stuck with this ROM as this version 2.3.4 is not rootable at the moment.

[Q] Need to unroot froyo 2.2

I have looked and looked but probably not in the right places... I have a rooted Evo 4G with froyo 2.2. I used unrevoked forever and know how to get the s-on back... I just would like to update the phone to the newest update and root it again. Is it still necessary to get s-on back then load the original ruu rom? I would think I just need to remove the unrevoked then update. The phone works I just want newer firmware on it... My apologies if I did not look for my response properly, but all I see is a reload the IMG file... I dont want to set back to factory... just wanted to post this question. Thank You

There is absolutely no reason to unroot. All you have to do is flash a custom stock ROM based on the newest firmware. A whole bunch are available for flashing in the Development forum.

It is much easier to leave the phone S-OFF and then either flash a rooted stock ROM or run a stock RUU. Then all you would need to do to obtain full root again (with stock ROM) would be to install a custom recovery and then flash a superuser.zip file, rather than turning the phone back S-ON and then going through a potentially complicated procedure just to reroot and possibly turn the phone back S-OFF.

Thank You guys sounds like a custom rom is the way to go... it would get rid of that IQAgent also... I'll look around for a nice looking rooted rom.
