[FIXED] Help!Cant flash any recovery images

Ever since I updated to the last OTA I have lost clockworks recovery image. Thus now I am unable to install the latest froyo rom.
I have tried to install the latest clockworks recovery image and Amon_Ra recovery through Rom Manager. Each time it states it is installed but everytime I try to boot up to the recovery image it gives me the following error:
E: Can't open /cache/recovery/command
and it just gives me the Android System Recover <2e>
Any help would be appreciated....

It sounds like you are not rooted.
If you accepted the OTA from Sprint using your system update on your phone, you are no longer rooted and will not have a custom recovery/root permissions. You will be unable to flash any custom recovery/ROMS/delete any sprint apps/Other Root only things until someone comes up with a way to root 2.2.
Have a drink in hopes that a dev will come up with a way to Root 2.2 soon!

I didnt update over the phone
What happened is I installed a rooted verson of 1.47.651.1 but in doing that it got rid of the recovery image... it definetly a rooter version because i can run apps that require root.. such as wife tether titanium back etc...
any other suggestions...

there's an update.zip around here somewhere that will allow you to boot into an early form of clockwork recovery.
so, assuming that you goofed something, but still have nand unlocked....
find that update.zip. put it and a .zip for a real recovery onto your sdcard. boot into hboot, let it run the update.zip, that will take you to koush's early clockwork recovery. use that recovery to flash a solid recovery.
done.
alternative method would be to use fastboot to erase the recovery partition, then put a new recovery in.

Here is the update.zip...Just extract Recovery.zip....Do this OR/AND what the Senior Member above said and you should be good

I actually tried the update.zip one already and it doesnt install... it will stated that the signature cant be verified and it will about the installation... havent tried the fastboot approach... I guess I will need to find out how to do that now

so from the looks of it I am screwed... I have hboot .79 if that matters and from the looks of it the rooted rom i installed screwed up my nand unlock.. which is why i think i can install any recovery images... i tried alot of the nand unlock tutorials and most of them I eventually get to a point were i need to write to /data and i cant because permissions are denied... great... oh well i'll keep on trying... any suggestions are appreciated...

If you still have super user, try this...same thing happend to me.

I'm having a very similar problem also. My Hboot is 0.79.000 too & after trying clockworkmod recovery, a few RUU update attempts, and attempting to change ROMs completely (not in that order) I'm at a loss, no success anywhere. I can't even get in to recovery anymore. It just reverts back to Bootloader menu where my options are Reboot, Reboot Bootloader, or Power down (& I think there is one other option that i tried and sent me back to the aforementioned screen). However, I can still load my pre-existing ROM...
Does anyone have any ideas if there is anything I can do?
TIA

you can erase recovery from rom manager and try to reflash. i would recommend reinstalling rom manager just to make sure it installed correctly. it installed bad on me once and corrupted my recovery trying to update it, reinstalled and installed an old recovery then the newest one and it worked.

Thanks for the suggestions all. I followed the instructions from link you posted using terminal emulator. No such luck, still reading HBOOT 0.79.0000 and running same ROM.
I also tried reinstalling (several times) clockworkmod recovery images and it effects nothing.
Should I try to completely unroot my phone again? If the images i just flashed didn't do it what will?
Im totally at a loss here. ARG!

hit there jtwonbly.......are you also running the stock rooted 1.47.651.1?

Build number 1.47.651.1 CL195459 release-keys

yea same here......and what is it that your trying to do...go back to stock ROM?

I'd like to go to any other ROM. Its as if I'm no longer rooted anymore.
I think I may try to start all over again using NeckFaces old tutorial on unlocking NAND w/o adb. I'm just not sure if that will fix the HBOOT file because I can't get in to Recovery.

OK Guys thanks for all your help but I have been able to get it fixed now!!!
I pretty much had to redo all of Toast Root tutorial and NAND unlock to get it working. Both Part 1 and Part 2 even though I was already running a rooted rom.
The original problem I had is I kept getting told to just try the nand unlock in part 2 but the phone wasnt having it. It wouldnt like the engineering build of the pc36img.zip
So I started from Part 1. Downloaded the rooted rom pc36img.zip and what do you know it finally let me install it. By the time I was done with both parts 1 and 2 I was able to flash a recovery image, get back to hboot .76 and I am now another proud owner of an Evo running a rooted Froyo!!!!

Custom rom install errors

So here is my issue.
I rooted the slide using eugene373 method.
(everything worked. Even ran rooted apps.)
But I wanted to add a custom rom. (MyFroyo5)
So I attempted to do the 'flash custom rom guide' but kept getting
"E:signature verification failed installation aborted" when running the first update.zip in the stock recovery.
So being "clever" I decided to get pass the stock recovery by doing the original root method. (Do an adb push update.zip /sdcard right after selecting apply update.zip)
It worked, and from clockwork I flashed the myfroyo5.zip.
BUT, the rom didn't flash correctly for some reason and my phone is stuck at mytouch slide screen
Can someone please help me to at least get back to stock so I can fix what I did wrong. Thanks.

Power off your phone
Boot up into the bootloader
Once in the bootloader start your loop in adb
Boot into recovery and good luck.
If you miss on the "offline", pull the battery and try again.

Also you were getting the signature failed because you never did the ENG build...just an FYI

Thanks for the reply. I did eventualy get my phone back. I redid the root process and flashed the teamfennix rom.
However can some one tell me more about flashing the ENG build? That's not on eugene's guide.

The guide that is in the slide rom bible is all that you need.
It has every step laid out really well.
There is also a video if you want to watch it done, its pretty simple and you shouldnt have any problems with it.

[Q] Clockwork Recovery

I updated to t-mobile's OTA update and was fine until i started getting phone process FCs. So while i wait for the t-mobile replacement phone, i thought i'd see some of the roms available.
I used the new root method to flash the ENG build, and it say something vaguely about installing Clockwork Recovery. But it doesn't say how to install it. With tis, i assume clockwork being installed mean when i do the Vol Down + Power boot and select recovery, it takes me to Clockwork recovery instead of the default recovery. I however only get to the default and have to load Clockwork from the update.zip file on my sd card.
Any help in explaining what to do (i don't want to go messing around with stuff like this blindly when i have to send the phone back to t-mobile so soon).

clockwork is an update.zip to be kept on the root of your sd card, you will need to flash it each time you enter recovery, when you have gotten to default recover then you need to press vol up+power, and then apply update.zip which should take you to clockwork

Thanks for the response. That is kinda what I was thinking after doing a bit more reading.

I have had no problems doing anything except getting the update.zip to get me into Clockwork. I flashed the ENG build according to the steps to the letter. (With some idiotic blundering in between.) I may just revert back to stock and try all over again. Any other suggestions?

G2 clockwork recovery

My phone is permanently rooted using visionary, and I have flashed clock work recovery from rom manager, but when I try to boot into recovery it just shows the phone with the red triangle? Can any one help me.
Thanks

From what I have read elsewhere, re-flash Clockwork Recovery.

Doesn't work.
Sent from my T-Mobile G2 using XDA App

You're supposed to only download and flash recoveries from Rom Manager if you're on wi-fi since T-mobile caches web pages but I was able to get around this by flashing an older version (in Rom Manager) and immediately reflashing the correct recovery (without rebooting or even leaving RomManager).
Of course you can always download the recovery.img file and fastboot flash it.

me too
Same issue. Trying to boot into recovery gives pic of phone with red triangle.
- I reflashed clockwork recovery (not sure is this helped)
- manually went into recovery manager from rom manager menu which loaded w/o problems
- selected backup and restore
- perform backup
seems like it is working...

Volume-up + power. If you already did that then i dunno

fix permissions in rom manager and reflash clockwork

recovery mode
newbie here, or course. back after 2 years away with BBerry, g2 cant get past recovery. i am looking for a way to get my device to turn back on... basically when i try to fastboot, it say i have the wrong image, or no image, fails to load E: sd card failed. i have acces to another G2 so i can get a copy of the stock rom image but has not worked::: i need assistance in this process. what do i need to load from the sd card to make my G2 turn back on or is this what bricking your device is? i have access to the recovery screen and can still load info from the sd card.
thanks for any info.

Are you saying your rom doesn't boot? Are you s-off? And if so can you get into recovery?
FYI - people generally don't fastboot from the SD, are you sure you were in fastboot mode and not hboot?

[Q] Need help with Root/Recovery

Okay, so here's the deal. I have an Evo. I rooted it using unrEVOked, updated the Clockwork and all was well. Well I started having a few issues so decided I wanted to RUU back to stock. Well then I noticed it still said S-Off and had the Revolutionary thing at the top in the Fastboot menu. I then tried running the Revolutionary Root and it said it had the S-Off already. It asked me if I wanted to download install Clockwork so I did. Now I currently have no recovery and don't believe I have root. The phone still powers on and works functionally. I am just wondering how to regain my root and recovery. Any ideas?

You have s-off correct but no recovery? Is that right?
Sent from my PC36100 using XDA App

Yes, and I used root checker and it says I have no root.

Have you tried flashing a recovery like amon ra
Sent from my PC36100 using XDA App

You need the two attached files.
Place the PC36IMG file (after you change the name to PC36IMG) on the root of your SD card. Then run the update through your bootloader (power off, then volume down + power button).
Then flash the su file from your new custom recovery.

Root access is a combination of S-off and the superuser app within whatever ROM you are running. If you had a stock rooted ROM or a custom ROM loaded onto your phone then you dont need to flash the superuser file as these already include superuser.
If I'm reading your original post correctly, and please correct if I am mistaken, your phone was/is already rooted. The only thing that seems to have changed was the fact that you somehow do not have a recovery. Instead of getting flash happy, try loading the recovery first via shorty's attached copy of Amon Ra. Then try to boot up into Android. Then you'll have three options.
1. The phone boots up and you have Superuser in your app drawer: Enjoy your rooted phone.
2. The phone boots up and you do NOT have Superuser in your app drawer: flash Shorty's attached Superuser file.
3. Phone does not boot into Android: Reflash a rooted stock ROM or a custom ROM of your choice.
I suggest doing it this way because you seemed to screw up your phone by doing what most would call a simple flash. It would be counterproductive to risk your phone's functionality by flashing something you don't absolutely need to flash.
