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.

[Q] Downgraded bootloader for CM6, need to restore for nandroid

All,
I was running Fresh 3.2 on my evo, rooted via unrevoked3. I wanted to try CM6 which required downgrading the bootloader to .76. Decided to go back to Fresh but I can't do a nandroid restore. I wound up having to go stock and running unrevoked again, bootloader now reads .79 but nandroid still won't restore. I'm thinking I need .93 but not sure.
Any help/thoughts?

Yeah you need to upgrade your bootloader back to the previous version then all will be well.

Any idea where I can find/download the later revision bootloader? I see .76 all over XDA and the web, don't see later versions for download.

i had the same problem last week. you did the right thing, but apparently didn't use the most recent stock RUU. once you reflash that, it should update your bootloader to 0.93. you can then re-root and restore.

I just downgraded my bootloader for cm also. My question is can you flash any other rom without updating the bootloader? Say I wanna flash a fresh rom. Would that work?

What was your original bootloader? 0.93? I believe there was no need to downgrade your bootloader for CM 6.1. I had sort of the same issue and this link helped me, I hope it helps you.

Well dang didn't kno that cm6 wasn't hboot specific. I just went off what he had in his guide. So with that pc36img I just flash in hboot and that will change my hboot to the .96? Will I have to flash a different rom right of way? Also are any other roms specific on what hboot u have? I don't mind setting up my phone again. That's the fun of it. Lol thanks tho for the link and helpfull info.

Yes, put the PC36IMG.zip in the root of your SD card and then just boot into the Bootloader. Accept update and you are good to go. So far on my end, I have flashed many many ROMs and did not have to load a different HBOOT. Good Luck.

God, I just KNEW I shouldn't have even tried to root... Please help =(

I recently got back a warranty swap Nexus One with an old version of android (2.2) and thought to myself "Hell, I might as well try rooting for once since it the 1-click method doesn't unlock the bootloader and you can always go back right?" Wrong
Well, I updated the radio as part of the Cyanogen 6.1 installation to radio version 5.12.00.08 and now that I don't want to be rooted anymore I can't seem to get the radio version back to normal to what it should be on 2.2.1
The 2.2.1 radio should be: Baseband version 32.36.00.28U_4.06.00.12_7
But when I updated to 2.2.1 it stayed the same: Baseband version 32.50.00.32U_5.12.00.08
Have I screwed up my radio? I just want to get my phone back to normal please help

Does the phone still function? Making calls, sending texts.. etc?
If so, then whats the problem? The radio update was probably included in the ROM you flashed, if you're experiencing problems, search the forum for the Radio you want and instructions on how to flash
Be careful though, you can brick your phone when flashing a radio.. so make sure you read the instructions..
Good Luck

2 things I am worried about:
1. Before I rooted and changed the radio, I could check for system updates and it would say I could to update to 2.2.1 ota... Now, after I unrooted and got it back to stock 2.2, I would check system updates and it no longer gave me the option to update to 2.2.1 (I had to manually do this)
This worries me since I don't want to miss out on all future ota updates if my radio has been screwed up when I flashed one earlier.
2. Radio has been slower since upgrading manually to 2.2.1 but still having the old radio in place.
Isn't the each radio optomized for the particular android build?
Also what about rooting causes the phone not to get the new ota update? Is it the changing of its radio?

What country is yor phone? And with what build did it came after warranty?
My guess the radio is just part of the update (if you flashed a stock rom)
I recently bought my nexus in holland it came with FRF91
And 5.08.00.04 radio so

Radio isn't per build.
There was a major change to adjust to Froyo in 4.06 radio, all the above are compatible with it, all the 4.04 and below are compatible with Eclair and not suitable for Froyo.
2.2.1 includes 5.08 anyway. Your not getting OTA doesn't have anything to do with radio.
You can flash any radio you want when you're rooted, using the guide found in Wiki.

Yeah I've benefited from newer radios. Dont sweat it your rooted, this is good.

It's the rom and recovery.
I really would not get stressed out about this. Worst case scenario is that you have to come on xda every so often and flash the update manually.

LOL, if ur on CM6 u already have 2.2.1 and worrying about future otas, root user update to latest version normally before unrooted people and u should have to problem updating, if u want to revert back to the old boring stock version just flash one of the shipping roms in bootloader by renaming them to PASSIMG.zip

1) From where did you upgrade to 2.2.1?
if you upgraded from rom manager or any ROM given by developer, they remove the radio and provide it as a separate update file.
http://www.tap3w0rm.com/hosted/android/radios/nexus-1/FRF50-radio-4_06_00_12_7.zip is the update for radio you want.
2) However, Radio update is not what you want. "Recovery" is what you want. Recovery is a piece of software that allows you to flash custom ROMS. did you install Amon's recovery or Clockwork (from ROM Manager) recovery?
You will not get OTA if you have one of these custom recoveries. you will need the stock recovery.
3) In short, you need to flash your phone with a completely stock google ROM.
follow these instructions
http://forum.xda-developers.com/wik...des_&_Tutorials#Unroot_.2F_Restore_your_Nexus

hmmm interesting...what makes you wanna unroot besides OTA? From what I see that's virtually no advantage to go back to stock rom
If you really want official OTAs, just make sure you check xda often when those are pushing out. There will be stock OTA updates hanging around.

Try this:
http://djmcnz.batteryboss.org/Kang-o-rama/froyo/radio/froyo-radio-update-signed.zip
Flash it from custom recovery. It will reboot, unpack the radio, reboot again in a few minutes, and you should end up back on the 4.06 radio. For what it's worth.
If you want to go back to totally stock unrooted, the most complete way to do so is using a PASSIMG file.

I installed Clockwork recovery when I first did the Cyanogen flash so how do I know if I still have it on my phone blocking OTA updates?
I had an old 2.2.1 update.zip on my SDcard from an old Nexus One that I sent in through a warranty swap.
Then I powered off and did the whole Volume Down + Power button.
I get the screen with the 3 androids on skateboards and clicked on Recovery
I press on recovery
When I see the triangle with exclamation mark I press power button + volume up and the only options I see are reboot system now, install update.zip from sd card, factory reset, wipe cache
I click on install update.zip (2.2.1) and reboot system now so the phone reboots but I still am stuck with the old radio. How do I know if I have stock recovery and will get OTA updates from now on?

I tried the steps exactly (PASSIMG.ZIP on sd card) but when I do the power + volume down step 7 doesnt happen. There isn't any screen looking for update files. I get the screen with the 3 skateboarding androids instead and no way to get the PASSIMG.ZIP file to work.

Can't you download a unrooted 2.2 rom from rom manager and then ota once its installed? Dont quote me though I've never actually tried to unroot

On my phone this is what I get in bootloader mode...
I start up the phone holding down the trackball, and I get the Fastboot with the skateboards. The first menu option, BOOTLOADER, is highlighted. I press Power and I get to the HBOOT screen (also with skateboarding androids). I wait 5-10 seconds and it checks for a PASSIMG on SD. Since I don't have one, it finds nothing and returns me to HBOOT.
Or alternately I boot while holding volume down and I get HBOOT directly. In 5-10 seconds it checks for PASSIMG. The only time it won't do that is if my SD is not installed.
You're saying that on yours it doesn't check for PASSIMG at all?

I am in a somewhat similar boat (though not exactly), a colleague of mine purchased a used Nexus One off of fleebay and it came rooted running Cyanogen 6 with Clockwork Recovery (for the Recovery Image).
My colleague wants it to be completely stock (which I do not understand as I find Cyanogen 6 to be far better) and asked me the resident Android guy if I could help.
I figured PASSIMG.zip was the way to go and downloaded the stock rom from developer.htc.com and renamed it PASSIMG.zip. I put the PASSIMG.zip file on his SD card and booted into the bootloader. It checks the PASSIMG.zip image but does not offer me option to install it. It simply checks it and then offers me the normal 4 options.
Any thoughts?
Dan

Read the Wiki, it has specific reference to FRG83 stock ROM now, which refuses to work in PASSIMG mode.

Try as update.zip through custom recovery? Then clear the custom recovery by flashing stock one...then delete superuser.apk + unroot?

Actually, it's just the ROM. Even if you have a custom recovery: a rooted, stock ROM will still receive OTA updates...

Yes but on quite a few custom recoveries, it will fail to install due to the signature.

True. If you are using anything earlier than Amon_RA 1.8 or the latest ClockworkMod, it won't install.

[Q] Reverting to stock - clarification required please

I'm hoping there is someone here to clarify some information regarding ROM flashing for me by answering a few questions.
I want to be able to flash ROMs and kernels, but be able to return completely back to stock.As I understand, this is not completely possible but I want for somebody to tell me I am wrong?
1... Will an RUU revert back to s-on?... that is what I'm assuming cannot be reversed.
If s-off cannot be reversed I plan to just root, then replace all apks with the odexed and zip-aligned versions from the Modaco ROM instead.
2... Will I still be able to flash an OC kernel with root enabled but with s-on?
3... If this is possible then I assume I can revert to stock from any of this with the RUU, correct?
Thanks a lot.

That's not correct, you can go back to stock even if you flash custom ROMs etc.
But do *not* just apply a stock RUU once you have a custom ROM, see this for more info as to why not - http://forum.xda-developers.com/showthread.php?t=838484
Follow the guides in the dev forum on how to return to stock.

Thank you for the swift reply!!
That's sweet music to my ears.
If you don't mind just giving me the nod to this then...
My Build number: 1.34.405.5 CL273326 release-keys
So to unroot and s-on I can follow the following little section from http://forum.xda-developers.com/showthread.php?t=835971 using the PC10IMG from the EURO generic 1.34.405.5 rom.zip.....
Step 2.) Restore factory BOOTLOADER, RECOVERY, KERNEL, ROM (THIS RE-ENABLES S-ON)
Place the factory firmware you downloaded in step 2 above on the root of your sdcard and rename it to PC10IMG.zip one you have done this power off the device and power back on by holding volume down and power. Once in the bootloader it will then scan your sdcard and find the file needed, be patient this can take quite a few minutes. After it finishes scanning you will then have to hit the Volume up key on the side of the phone to restore the software. This will take approximately 5-10 minutes. The phone will reboot in the middle of the update to restore S-ON once rebooted it will then scan sdcard again and resume flashing. Once completed you will have to hit Power to reboot and boot back into the factory restored android os.

..... then just run the 1.34.405.5 RUU?
Or do I need to downgrade to an older ROM 1st as stated in that link I looked at above?
Thanks again

I don't think you need to run that RUU at all, but please wait till someone else confirms if you're going to try this yourself, I don't have enough experience yet to say for sure.

Ok no problem, I'll worry about it another time. Now, know I can go back if I need to, I can start playing!!!
thank you.
If anyone else can add to this please do.

[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.
