Rooting Help

I downloaded the mistakenly flashed android 1.6 recovery image while trying to flash Cyanogen 4.1.999 . And I lost my root . Now I am unable to root my G1 by 1-click rooting process. When I run recovery Flasher, both the i am not able to backup the recovery image and install the new recovery image. Is there any way to root it.

I did a similar thing. You lost your recovery image, yes? I used downgrade-firmware method... DREAIMG.NBH+g1 root in a google search should get you started...or search the forums here sucks you got to start from scratch tho...there may be a way to downgrade to doughnut and try running the 1-click root app to restore a custom recovery image?

That means i need to downgrade to android 1.5 before being able to run Recovery Flasher.

Find a tutorial on the non 1 click root method and reflash a custom recovery image via the rc29 exploit...the power of google is in ur hands or at ur fingertips.

Look through the q&a's there is a pretty straight forward tutorial that gets you back to a rooted state.​

you dont need to reroot your phone. look at the last few posts i made in the cyan 4.1.999 installation support thread in this section. it should get you where you need to go. if you need help, post there or pm me

Question about FROYO 2.2 --> Stock ROM with Amon Recovery and SuperBoot with Himem

I am running the Modaco Stock ROM Kitchen "10/May ERD79 -> EPF21B - Stock ROM for Nexus One images / zip / online kitchen (optional root / insecure / himem)":
http://android.modaco.com/content/google-nexus-one-nexusone-modaco-com/300414/10-may-erd79-epf21b-stock-rom-for-nexus-one-images-zip-online-kitchen-optional-root-insecure-himem/
- ROM = Stock EPE54B
- BOOT = SuperBoot with Himem
- RECOVERY = Amon_Ra's Nexus One Recovery 1.7
- The FROYO 2.2 OTA will work automatically ?
- Do I have to go back to the STOCK Recovery image ?
- Do I have to go back to the STOCK Boot image ?
- If I get the OTA can I save it as OTA.ZIP and then from the Amon's Recovery do Update from Zip ?
Thanks

No need to spam MoDaCo AND xda...

From what I understand you will NOT get the ota if you have a custom recovery. We will have to wait until the .zip file is out and flash it from SD like every other rom.

you will get it with amon ra but won't be able to flash.
I'm tired of all these froyo threads.

I followed the instructions in the following thread:
http://forum.xda-developers.com/showthread.php?t=614850
And after the installation I got Build ERD79 (original shipping ROM), almost immediately I got the OTA update to 2.1-update 1 and now my device has the build ERE27 (official update).
That means if you go back to Stock ROM and Recovery, the OTA process should work fine.

So will we be able to flash the official update.zip once it is posted with the custom recovery or would we have to revert back to flash it all together?
I've seen some say yes and some say no.
Thanks!

Plea - Need help. Explain correct way to root FRF91. Noobs want to know!

OK friends, I will pass the favor to others for current information. I've been all over the forums looking for the safest way to root the FRF91. The problem is, the pages with some instructions have dead links to files and missing information about recovery. The stickies are gone or are showing how to root older roms only. The information is partly available in multiple places only. There are people searching and still confused on the correct procedure to root with or without an unlocked bootloader. I for one, am not sure when to use a recovery file or if any is needed. If some veteran or experienced user can finally post accurate and complete instructions on the exact procedure to root the FRF91 rom, others will be eternally grateful.
1) Please explain how to root FRF91 (aware 91 has to be downgraded).
2) If a recovery rom is needed.
3) How to downgrade to an earlier rom for root access.
4) How to upgrade back to FRF91 (or custom rom).
Yes, this question has been asked a number of times and most of these posts are passed over and ignored. People want to know and will keep asking because there are not clear instructions on rooting or recovery for this latest rom.
Thanks for your time.

((A))
1) Wait for [email protected] modaco to update his superboot.
2) Use that.
((B))
1) Flash AmonRA recovery using adb/fastboot.
2) When flash is done, reboot into recovery using fastboot, or pull the battery when it's done being written (but NOT before!!!!) and reboot into recovery with the trackball+power combo. If you boot normally without root, it will overwrite the recovery with the default one.
3) From within AmonRA, flash a rooted ROM using .zip file.

what i did is installed a clean 2.1
Then i just let the OTA do its job.
Installed OTA
downloaded Root Access via LINK
Flashed it in Amon Ra
Done.
If you allready have un-rooted FRF91 just use the link.

Which clean 2.1 are you referring to? Please post a link.
Can I downloaded Root Access via the "LINK" only without downgrading to 2.1 and flash Amon Ra Recovery if FRF91 is already OTA installed?

1) Please explain how to root FRF91 (aware 91 has to be downgraded).

2) If a recovery rom is needed.
Custom recovery rom is not necessary to root, only to flash custom ROM
3) How to downgrade to an earlier rom for root access.
See #1
4) How to upgrade back to FRF91 (or custom rom).
Go here and pick a rom that based on FRF91 Froyo. Cyanogen Beta is out, as well as Enomther's Official Rom 2.9.2

[Q] lost recovery after 2.2.1 ota

i had cyanogen custom ROM installed on my nexus i used the ROM option to install stock froyo ROM with superuser, after that I had the stock fr191 ROM then the O.T.A. update hit my phone and since that i lost my recovery I still can access it only by pressing power and volume + but it doesn't give me any option beside flash update.zip is there a way to install recovery without messing the FRG83, 2.2.1 its very good no problems I just want the htc camera with the 720 support. and i also miss the back up restore option, any help?

I used the rageagainstthecage method to gain root and then flashed the recovery with the method described here: http://forum.xda-developers.com/showpost.php?p=7392149&postcount=61

thanks allot but the recovery image in the link is not valid

Read my signature, read the relevant guides, and download the new recovery listed in "Recovery".

[Q] How to get back to vanilla from rooted FRF91 with custom recovery?

A couple of months ago I rooted my N1 FRF91 with Universal Androot. Later I flashed psfMod (based on CMW) custom recovery using flash_image recovery.
Now I don't have any use for custom recovery or a rooted device anymore, and want to get back on track to be prepared OTA 2.3.
I have received notifications for 2.2.1 OTA (2-part update), but the device just locks up during the upgrade and gets back to rooted 2.2 after a reboot.
So how do I apply the 2.2.1 update? Could I just flash the original recovery with flash_image (and what file should I get in that case), unroot with androot and just use the OTA? Or is there any better/easier way?
The question feels kinda nooby, but the only guides I find is to get back to shipping conditions (Which I don't want to keep my settings and so on),using fastboot which I can't since my bootloader still is locked or assumed that you are using a custom ROM which I don't.
Thanks for your help!

There is no need to get rid of a custom recovery or root to apply those updates. This has been covered in many threads.
This is what I would do. Use flash_image to flash Amon_RA 1.9.0 recovery. Then download the update (make sure you download the correct one: there is one that is FRG83D from FRF91, which is what you will need if you are running FRF91)and save it to the root of your sdcard. Then boot into recovery, and flash the update. (You will lose root and your custom recovery, but just root again if you want.) That covers part 2 of 2 of the update.
If you want to flash the first part, dowload the HBOOT 0.35 update file (floating around the forums) and place it in the root of your sdcard. Boot into recovery and flash that. You may have problems flashing certain custom recoveries after you flash the 0.35 HBOOT.

Thanks for your reply. If I follow your steps, the 2.3 OTA will work when it eventually comes?

If you keep a custom recovery, you will still get the notification, but you will have to manually apply it. If you keep the stock recovery, it should be able to apply it automatically. No word yet on if the newer HBOOT is a requirement for 2.3 or not.
