[Q] Q. Is it possible to unwittingly lose Custom Recovery? Please Help.

Firstly, my nexus one is Locked + Rooted with Stock FRF91.
OK, So I rooted with 1-click, installed a custom recovery (first Clockwork then Amon RA 1.8.0.0).
Did a full backup
Tried out a couple of Roms
Reverted to Stock from backup. All good!
Now 1 week later, I really want to try MiUI Rom so I power on phone with VOL-, select Recovery - all I see is the yellow exclamation in a white triangle with a green Android below. Isn't that normal / stock recovery???
Could the FRG83 OTA that I have not installed (it is still bugging me to do so ) have restored the stock recovery?
Did I clear something / do something wrong when performing the Stock backup or restore?
TIA for any advice.

The OTA update did install, and in the process replaced install-recovery.sh and recovery-from-boot.p, which meant that the stock recovery was automatically reinstalled by the OS on reboot.

Hi rusty, thanks for the reply. I have not installed the update, it is still asking to be installed. I even checked the build number in about phone - frf91.
Are you saying that with out my explicit permission the ota has modified my phone and restored the stock recovery - that certainly would explain it.

I misread your post, sorry about that.
However, restoring your backup is probably the cause, due to the same reasons above.

To simplify, you can lose your recovery in this fashion:
Start with stock ROM
Root
Install custom recovery without removing the .sh and .p files mentioned
Boot up phone
Now, if you install custom recovery using several automated methods, OR manually remove the files previously mentioned in thread, no problem. But if those files remain the stock ROM will automatically run them and restore the recovery image. Happens to a lot of people.
So likely that's what happened; restoring and using your stock ROM had those scripts in the image.

Thankyou both for your help. It makes a bit more sense now.
So in order to get back to a custom recovery, will I need to reinstall it or will removing these .sh and .p files do the trick?
Ps, what is the exact location of these and how would I delete them (i assume they are system/ protected)
Thanks, Steve.

You'll have to remove/rename the files and flash it again.
They are: /system/recovery-from-boot.p and /system/etc/install-recovery.sh
You could rename them:
Code:
mv /system/recovery-from-boot.p /system/recovery-from-boot.p.bak
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
or remove them altogether
Code:
rm /system/recovery-from-boot.p
rm /system/etc/install-recovery.sh
My advice would be to rename, just incase you feel like stock recovery again at some point.

Perfect. Understood.
I'll try to remember to update this thread with how I get on once i'm done but even if I dont, I think the info contained is pretty clear.
Thanks Rusty & khaytsus.

Also I'm pretty sure that if you use ROM Manager to flash custom recovery, it automatically zaps the files that would otherwise revert you to stock recovery.

I did use rom manager and I have since done clockworkmod through rom manager but when I go into recovery I get the stock one. that's why I did the manual process installing ra after clockwork the first time round.
Anyone else has that where rom manager seems to install the custom recovery but then when you go there its stock?

E: can't open /cache/update.zip - need help

Hi folks.
Having some problems everytime I try to boot in recovery mode or try to install a ROM using ROM Manager.
when my phone boots into manual recovery mode, I eventually get this message.
E: can't open /cache/update.zip
(bad)
Installation Aborted
I've made sure I have my update.zip in the root of my internal sd. In manual recovery mode, I even selected the "reinstall packages" option and it would execute just fine and then reboot my phone.
So I'm stuck scratching my head as to why I get the error message above and can't access the additional menu items in the manual recovery mode.
Help please as I am a noob to this hacking stuff.
THanks everyone!

after you reinstall packages and it reboots, do you select reinstall packages again? you should because it takes 2 times to get into clockworkmod

When I boot into manual recovery mode and select reinstall packages, the phone reboots and turns on...it doesn't go back to the <2e> recovery menu. Does that sound right?

There's your problem. Your new file should NOT be named update.zip. The update.zip package MUST be the one for CWM. Its this update.zip that is used when you choose reinstall package and then you get into 2e recovery mode.
Name your file something different so it won't interfere with the update.zip of CWM on your sd root.
If you deleted that CMW update.zip file just return in CMW and reinstall the Recovery. It will push the update.zip again.

Not sure I completely understand.
to give clearer picture, here is where my update.zip file is located.
/sdcard (folder)
within the /sdcard folder are the following:
/Android
/clockworkmod
/DCIM
/download
/layar
/media
/sd
/tmp
...and finally, my update.zip file
so I'm assuming the update.zip is in its proper location within the /sdcard folder
With the file there, I reboot into manual recover and select reinstall packages...it executes and the phone boots up and turns on. It doesn't return me to the manual recovery mode again and I'm assuming it is during the return to the manual recovery mode where I can access additional menu items such as install from SD.
So I'm assuming this update.zip file I have now is the one for CWM. Thoughts?

at what point did you FLASH clockwork recovery manager? are you sure that update.zip file thats on there isnt for something else like the root?

to be honest, at this point I'm not entirely sure. the update.zip could be for the root.
what do you mean by flash clockwork recovery manager...when I go into ROM Manager, under the Recovery heading I see the following options.
Flash ClockworkMod Recovery (Current Recovery: ClockworkMod 2.5.1.2)
Reboot into Recovery

-First delete every update.zip you have in /sdcard
-Return in ClockworkMod and tap on Flash ClockworkMod Recovery (yes it will reinstall the recovery, thus copying the right update.zip onto the /sdcard).
-Now rename your .zip you were trying to install (ie. my_new_file.zip)
-Copy it in /sdcard
-Reboot into Recovery and select Reinstall Package (if it goes directly into the recovery menu even better)
-Now you should be in the CWM Recovery.
-Select the "install zip from sdcard"
-Select your "my_new_file.zip" to flash it.
-Reboot in normal mode.

ok...so I went into ROM Manager application and tapped on Flash ClockworkMod Recovery
A status bar displayed and it completed like in a second or 2. Then I went into my /sdcard directory and there is no update.zip file there. Doesn't seem like it is copying the update.zip file into the directory.

No biggy, just means the recovery is correctly installed.
Just follow the procedure and try it like it is and see if you get a error.

flashing clockwordmod recovery doesn't install an update.zip on your sd card (1 click roots do).
All flashing CWM recovery does is install clockwork recovery in place of standard recovery mode.

ok...so I've deleted the update.zip file from the /sdcard directory.
went into ROM Manager and clicked on Flash ClockworkMode Recovery
Rebooted my phone and got to the <2e> screen. I click on reinstall packages and now it gives me an error message that the update.zip cannot be found.
So then I used z4 root to unroot. I then rooted my phone again and found that it didn't place an update.zip in the /sdcard directory. So it appears without the update.zip in the /sdcard directory I cannot reinstall packages. But if I put the update.zip file back into the /sdcard directory, I can reinstall packages, but then I'm back to the same issue again....feels like a never ending loop.

ok...finally got things to work. Looks like I had the wrong update.zip file in my /sdcard.
I searched the forums and found the correct one that now allowed me to reinstall packages twice and take me to the full recovery menu.
for others that may need the update file, it is located here:
http://forum.xda-developers.com/showpost.php?p=9850347&postcount=1687

That was it!
Awesome, thanks! I had just returned my Captivate to AT&T for a replacement today, and I was pretty convinced the shysters had made it harder for me to re-root and mod my phone. Now, how do I wire you a beer?

If you downloaded with your phone right after rooting, make sure you delete the update from the general sd card folder and move the update from your download folder to the general sd card folder. I had flashed with odin and rom manager last night and i had to install it that way due to fact clockwork has been down.

[Q] How to delete install-recovery.sh in milestone?

I found the following warning in a Rooting guide for Milestone:
If you applied an OTA update before, there is a script run at every system boot that checks and re-flashes the recovery when its checksum doesn't match. In such case, you have to avoid booting to android after the vulnerable recovery flash. Boot directly to recovery when RSD Lite restarts the phone (hold camera button) and from there remove the /system/etc/install-recovery.sh file.
rm -f /system/etc/install-recovery.sh
Could someone provide me detailed information on how to access the recovery and delete the install-recovery.sh file? Also does this reflashing occur on all Milestone which has received any OTA update?

Over 30 views, and still not a single reply. Come on guys, I know you are better than that...

First copy AOR to the root of sdcard.
Flash the VR. When the phone reboots and before it shows the M logo, press and hold the "x" key for a few seconds till the M logo is seen, then release. It should show you the triangle with exclamation mark. Press up volume button + camera button. It will show you recovery menu. Choose second option " apply sdcard update ".
After AOR menu is shown, choose console and type the command.
Done.

i first update my Milestone to the official 2.2.1.
Then copied the AOR 3.3 to sd card.
Then flash VR. then directly start to the recovery and flash the AOR.
After a while AOR starts and i type rm -f /system/etc/install-recovery.sh in the console and then "exit"
But i have to flash the AOR every time, because the stock recovery starts when i press camera button while startin (bootloade 90.74)

In the froyo menu, select Install Open Recovery at boot
After you select that, it will load AOR automatically if you hold the camera button (or X for 90.78 bootloader)
If you wipe caches, then you lose that so you would just Install OR at boot again

I flashed vulnerable recovery, flashed AOR and rooted my phone, and deleted the install-recovery.sh using the console command. I also selected the Install open recovery at root from the Froyo menu. However, my phone returns to the previous recovery menu every time i enter the recovery, and I have to flash AOR all over again.
Is there anyway to prevent this?

I'm having the exact same problem. Still looking for a solution. When I used root explorer to try and find install-recovery.sh BEFORE i started the whole process of trying to install VR, i couldn't find it (I previously used SuperOneClick to root after doing the official 2.2.1 update from Telus/Motorola). I suspect the file has been renamed and moved with this new 2.2.1 update.

[Solved] Can't flash Clockwork Recovery.

I've read the guides, tried manual and the simple download from the Android Market. Here's what happens:
I've rooted my Thrill with SuperOneClick 2.1.1. It was a successful root from what I can tell, it added Superuser into my apps, and I was able to download Rom Manager from the Android Market.
If I try using Rom Manager and click "Flash ClockworkMod Recovery" It appears to install. But when I hit "Reboot into Recovery" it just reboots like normal.
If I try to manually get into recovery mode by holding volume down and the 3D button it just boots into the stock recovery mode.
When I try to manually install Clockwork and copy recovery.img to /data with cmd I get this:
failed to copy recovery.img permission denied

Thanks for any help, I'm hoping it's just a small little step I missed.

This is covered in the cwm thread in development section you need to use a file explorer that has root access and change permissions to the /data folder. You can use es file explorer, its free. Open it go into settings then browse as root... not really sure exact steps but they are in the came thread.

O my such a small step I missed! Thank you! Ill try this later today.

Permissions of /data are set to R/W but I still get the same error..
I'm starting to wonder if the cause of this is because I tried using Rom Manager to flash clockwork, THEN tried the adb method. Maybe it already being there is causing the permission denied?
edit: so it looks like it was as simple as me looking over the permissions and thinking I saw everything was checked, but really the two checks from the left under "other" were grayed out lol, checking those fixed it.

Thrill 4G Clockwork mod Instructions for New Rooters

If you are new to rooting your phone, there are simple ways to go about getting clockwork mod onto your LG thrill
You can root it easily with the 1 click root tool (I dont have the link on hand) after installing the LG Drivers from the LG Website.
Then, Download Rootexplorer, Rom manager (which i think is installed with 1 click root along with superuser)
First thing, download the recovery.img here after installing ADB guide is located here
After downloading recovery image, go to your pc's user folder C:\users\yourname and move it to there, that way there is no mistaking its location for adb
Now, on your phone you first need to go into root explorer, go to the /data folder, long click and go to permissions and select all available boxes and also make sure your device is in R/W mode not R/O mode.
Run CMD as administrator and do the following:
adb push recovery.img /data
then type:
SU
(this makes superuser active)
then:
dd if=/data/recovery.img of=/dev/block/mmcblk0p6 bs=4096
then after clockwork is flashed to finalize the settings type:
rm /data/recovery.img
reboot
Presto, Clockwork Mod is installed, remember you can access the clockwork menu via rom manager menu, or 3D+Volume Down +Power releasing the power button when the LG screen appears.
I will soon post onto this, how to update to gingerbread just making sure it works well on my own first. also, working on ICS as well.
Hope this helps anyone who has had trouble with it!
