Hi all, I followed the directions here to root my phone and unlock my bootloader and things have been great!
But, I can't get install the OTA update. When the auto-updater failed, I tried the manual install per these directions:
androidcentral.com/how-manually-update-your-nexus-one (new user can't post links)
However, I never see
"Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle."
or
"Apply sdcard:update.zip"
I do have the option to "Flash zip from sdcard" and I select "SDCARD:update.zip"
Then I get the following
Build : RA-nexus-v1.5.3
.... (Confirm install stuff)
Install from sdcard...
Finding update package...
Opening update package...
Verifying update package...
E; No signature (208 files)

You need to follow these instructions.
Can you give me some more info about this? Will this wipe all my settings and apps? Will I have to unlock/root my phone again afterwards? Why is this necessary, is there a problem with my build or is this something that everybody has to follow who did the unlock/root process.

You dont have to wipe, unless maybe you are coming from a Cyanogen ROM.
Its something that everyone who is rooted has to do. You will have to install the modified update, and then flash the boot.img of your choice, unrooted/rooted/rooted with himem.
So download this under "ERE36B - update zip format": http://android.modaco.com/content/g...-online-kitchen-optional-root-insecure-himem/
and then go here and select which one you want

I think I may have used the Cyanogen mod, is there a way to tell and should I still follow these directions if so?

If you go settings>>about phone>>look towards the bottom and look for something that says cyanogen.
You can still follow the instructions, but if it doesnt want to install the update, or you get force closes once you reboot, you will have to do a wipe and do it again.
Also if you want the latest radio, install this from under the first link: "ERE36B / 32.26.00.24U_4.04.00.03_2 radio - update zip format"
Ok, I don't see anything about Cyanogen so I'm going to go ahead and try to follow these directions. What do you mean by "new radio"? My build number is ERD79
So just to confirm that I'm doing the right thing, I want to use this image "Superboot for ERE36B with himem enabled" for the most updated that will root and unlock and this will contain the OTA update?

The update in conventional zip format, with root options is here!
P
Works mint! I was running Modoco 1.3 ROM, heres the steps I performed:
recovery install: update-nexusone-ERE27-signed.zip
recovery install: update-nexusone-radio-32.24.00.22U_4.03.00.21_2-signed.zip
./fastboot-linux boot boot.ERE27.superboot.img
./fastboot-linux flash zimage zImage-2.6.29.6
./adb remount
./adb push bcm4329.ko /system/lib/modules/bcm4329.ko
Can I flash this manually WITHOUT being rooted?
I posted a thread on updating without root: http://forum.xda-developers.com/showthread.php?t=627533
Modaco's page confused me a little.
Does the "Main update" include the radio update, or did he split that off and they're completely separate?
Can the main update be installed using a rooted, but stock, rom and recovery?
In other words, if I just want exactly what the OTA would give me, on my rooted (by superboot) but stock N1, what do I need to do?
Thanks!
I'm completely stock rom / not rooted and I just did this:
http://androidforums.com/nexus-one/41504-how-force-2-2-2010-ota-update.html#post316090
1. Get the update from Google: http://android.clients.google.com/updates/passion/signed-passion-ERE27-from-ERD79.a487b405.zip
2. Put the update on your SD card & rename it to update.zip
3. Boot in recovery mode (hold down trackball + power)
4. Go to bootloader -> recovery
5. Now there's a picture of a droid with a triangle
6. Press the power button + volume up
7. Apply sdcard:update.zip
8. Updating
9. Reboot system now
10. Enjoy the multitouch

I'm in the same exact boat as you. I rooted my phone last week because i was eager to get multitouch working, so i followed this tutorial:
theunlockr[dot]com/2010/01/21/how-to-enable-multitouch-browsing-on-your-nexus-one-using-the-native-browser/
So now when i try to apply the OTA update manually in recovery mode i get:

Does anyone know what i can do to get this OTA up and running? Im rooted but i havent flashed any custom roms or recoveries either.
This is my first android phone so i'm a bit of a noob and new to the scene. Any help would be greatly appreciated

check that guide out, it was simple and easy to follow...
Thanks JHaste.
But those are pretty much the exact instructions I followed that gave me the error.
My phone is rooted, but running the stock rom.
No custom rom, no patched browser.
The only changes I've made since rooting it are to copy some Thai fonts into the fonts directory.
The exact specifics of my error are posted in:
http://forum.xda-developers.com/showpost.php?p=5528501&postcount=118
Very similar to what PhantomRampage listed, but a slightly different cause, I think... (his is an error on Browser.apk)

Thanks for trying but as i said before, i tried that and it fails because i have an unlocked bootloader.
Sorry if my first post was confusing, ill try again.
I unlocked my bootloader and rooted my N1 the other day, i also modified and added some files to get pinch-to-zoom working on the native browser. To do that i followed some tutorial on theunlockr, i cant post direct links so google it and you'll find it easily.
So, now i want to apply the new OTA update but it fails, either because i have root access or because i tampered with the browser files im guessing.
Knowing all that, what can i do to install the new update?
Also, will i have to download patched updates from now on since i rooted my phone? I'm really hoping i dont have to; i'd prefer to install the ota updates as they come out officially.
might have found a solution
check out:
forum (dot) androidcentral (dot) com / google-nexus-one/6469-will-my-n1-receive-ota-ere27-update-cyanogen-mod (dot) html
seems to be just what i was looking for but i think i want to re-flash the stock firmware instead, i want to stay as stock as possible so i can install future OTA updates without having to go through all this trouble. Can anyone help me with that please?
Anyways, i hope my link will help some people. Sorry for the double post
Closing Double Thread (it's also at Development).
Please do not duplicate threads if not necessary.
I just got OTA notification, should I install it? I'm rooted and have custom recovery.
If you're running stock 4.2.2 (you didn't flash a custom ROM or applied other system changes), then yes go ahead and install the OTA.
Check this thread for more info.
4.2.2 OTA Failed
Hey
I have a rooted Nexus 4 also. Running mako kernel. I got the 4.3 OTA update. Proceeded to install the update. But the update failed, then directed me to the stock recovery screen with the red warning sign. I rebooted the phone, went to Settings -> System Update, the 4.3 OTA is no longer there, and the phone is still running 4.2.2. What should I do to get 4.3?
I'm a noob.
Thank you for your help.
By "mako kernel" do you mean the stock kernel?
Why did the update fail - did you see the error message?
Since you're rooted, you have the option of re-flashing the OTA update:
1. The update zip should be in system/cache. First copy the zip file into your sdcard (ie the root folder).
2. If you don't have a custom recovery already, I suggest you use one to flash the OTA update. Install GooManager from the Play Store and install recovery. The default recovery is TWRP. Google Youtube for the process if you're not clear.
3. Once you're ready, reboot into TWRP recovery and select the OTA update file which you copied over in step 1. This should update you to 4.3.
4. If flashing this is successful, select the option to wipe dalvik cache, then select reboot device.
5. The phone will boot up and you should now see that you're on 4.3. You can now delete the OTA zip from your root folder.
6. If you want to re-root your phone, here's where TWRP comes in handy again. Download SuperSU from here, and paste it in the same root folder you placed the OTA zip before.
7. Now boot into recovery again, then choose to flash the SuperSU zip file.
8. Reboot phone and check that you have root access.
Good luck.

Can you please expand on Step 1?
Im not so sure as to what you mean and how to complete that step
Sorry for the trouble
Thanks
I believe that's the faux kernel (not sure if that's the correct name; I don't keep up on kernels). You will need to flash the stock one from Google if you want to apply the 4.3 update.
Search this forum for more info on doing that; I think the thread I linked to earlier should have instructions.
Expanding on step 1:
- When your phone automatically downloads the OTA zip file, it will store it in system/cache. Open a file explorer app (like Solid Explorer), press back a few times, and you should see the "System root" folder. Look for the "cache" folder, and the OTA zip file should be inside.
- Copy this OTA zip file into your "Internal memory" folder. Actually you don't really need to do this step, however it's the easiest folder to select when you go into recovery mode.
I managed to get the 4.3 OTA again
It downloaded and I'm now in the process of installing.
The phone reboots, (bootloader is unlocked), I see Droid, with the stomach open, blue bar right underneath it.(The screen that shows up with all updates)
Now the progress stopped. The blue bar stopped moving. This is the message on screen
Install Untrusted Package?
THIS CAN NOT BE UNDONE.

When I choose "Yes- install untrusted zip", the installation fails, with the red warning sign and the droid laying on the ground.
Now I'm at the ClockworkMod Recovery v6.0.3.1 screen, given the following options.
- reboot system now
- install zip from sdcard
-install zip from sideload
- wipe data/ factory reset
-wipe cache partition

Thanks again. I appreciate it
That message is very similar to mine when I tried to apply the update using my cwm I have my baseband flashed to .33 so I can enable LTE idk if that's the problem causing it
Sent from my Nexus 4 using xda app-developers app
@cliew:
Signature verification check failures tend to happen on CWM, which is another reason why I recommend using TWRP instead.
You can try following step 2 of my initial post and see if that works.
If the update still fails when you use TWRP, that means you've altered some system files that conflict with the OTA. You'll get another error message when that happens, and it should point to whichever file is in conflict.
---------- Post added at 09:35 PM ---------- Previous post was at 09:33 PM ----------
@droidman89:
Yes, I believe if you've flashed different radios, that would most certainly stop the OTA taking. If you haven't already done so, you'll need to re-flash the stock ones in order to update.
I have the OTA file. Assuming that I'm on stock everything but rooted with a custom recovery, will the install still work, or should I reflash stock recovery as well?
@viewfindr
If only your recovery is custom - and no other system files have been modified - then yes, you should be able to take the OTA successfully.
Rooter? Lol just root or rooted. Sure it's a typo.

It should be in System root / cache. The other stuff in that folder (at least for me) are three folders named backup, lost+found and recovery.
If you can't find it there, it's probably because it's been some time since your OTA arrived. Which means it's now been cleared from cache.
If that's the case don't worry, because it'll come back again. Alternatively you can flash the update manually using the 4.3 image elsewhere in these forums.

In order to take the ota you need the original recovery from the build you have now. Once you unzip the firmware (xml.zip) it will be the recovery.img file. Flash that with Rashr tools from Play. I assume you have a VIRGIN phone/root file structure, if not the ota will still bomb out. In that case RSD LITE restore the whole XML. Be sure to backup the current ROM even if it is not custom.
The stock recovery img... But even with that it still may not update if you have modified your system any.... Debloated deodexed xposed these things may prevent the update..

Do anyone know if there's already CWM recovery for Zenfone 3 ZE552KL?
I dont think many people use clockworkmod anymore, though I think I still have it on one of my backup phones.
Most people here use TWRP as a custom recovery on their ze552kl, myself included.
Procedure is the same to flash it as cwm.
Check the guides section

Sounds like you may have a corrupted download. Try downloading it again via your computer and then transfer it over.
I literally JUST updated to the the latest version of nougat off Asus' website (came out two days ago!), only error I got was Error 7 which I bypassed by deleting the first 7 lines of the updater script. No problems over here?
I am assuming you have an unlocked bootloader, TWRP v3.0.2+ and have read through the guide on how to flash, including the no-verity.zip.

I suppose it's best to start from scratch.
go here and unlock your bootloader.
go here, and perform Step 1 only for now, in case you have a corrupted recovery.
download the latest Nougat firmware from Asus' website here (in case your original one was corrupted). Open the archive and edit the updater script (/META-INF/com/google/android/updater-script) to remove the first 7 lines of code, so the script starts at "ui_print....." now. Save it, and load it onto your sdcard.
Boot into recovery with "volume up + power", select "wipe"-->factory reset. Then select "install", select the firmware, and let it do it's thing. When it's done, select "wipe Dalvik & cache", and then reboot and wait no longer than 10min.
Once she's up and running, go back to here and perform step 2.
click the "thanks" button for the two gents that wrote the above guides, without them we'd both be lost, lol.

You should try only one - 2.21.617.1 or eventually newer but it would have to be for your model (US, SingleSIM my best guess).
Take the 2.21.617.1, save it properly named on the SD Card and boot into update.
And be more specific - what is the "brick" according to you?

It is not HTC file. Someone has been playing with it.
Third one:
If you can get into TWRP you could simply install LeeDroid 2.1 that is for single and double SIM recovery installer and save all the hustle.

I was able to downgrade to 1.64.617.17, however when I now go to update OTA the phone says
Can't update software
There was an unexpected error and the file system may be corrupted. Please contract HTC support for further assistance.
How do I fix this?

First - explain, how have you managed to perform the downgrade?
Second - do you have TWRP? If yes - OTA won't work! It has to have the original HTC recovery to handle the upgrade package.
Flash TWRP, If you already have it. Just boot to recovery and flash new custom rom or if you want stock rom so you can downgrade to nougat and then update to Oreo.
