[Q] e:can't open /cache/recovery/command - myTouch 3G Slide Q&A, Help & Troubleshooting

I'm trying to root my phone and my computer cannot pick up the connected device. I've tried several methods of rebooting and the latest from kingofyo1. I cannot get my phone to boot into recovery mode and see this message on my phone when trying to do so "e:can't open /cache/recovery/command"
what are my options and someone help me with detailed instructions or point me to a thread with the answers?
Thank you

Mine always gives me that message before pulling up the clockwork mod recovery. Do you have the clockwork mod "update.zip" at the root of your sdcard?

did you used Eugene's method of root and cant get to clockworkmod recovery? i ask because if you are rooting this late, you must follow the newest root method thanks to the recent ota. the newest method instructs to use eugene's method down the line of rooting. if so, did the eng build load fine?

did you forget that there was a section of the forum called Q&A where you go to get your questions answered? its right here ---->http://forum.xda-developers.com/showthread.php?t=701241&highlight=root+method
also that error will always be there. go thoroughly read through the rooting thread and if you follow the instructions TO THE TEE you will have root.

Is that what you see right after pressing Vol Up and Power? If so, not a big deal, I see it all the time. Just press the keys again and it should come up with the recovery screen.

Wow, you need to do some more reading lol. That is normal, what you need to do now is flash the ENG rom in order to get into clockwork much easier and flash things without the need for signing.
If you are trying to get into recovery to finish rooting though, after the '.img' stuff finishes, use the volume to highlight recovery then press power. Once it reboots press 'vol up+power' now you're in recovery.

[Q]

Can anyone help me get this phone rooted I have done it before and had no problems but this phone is driveing me up a wall and I dont know what to do I have tryed different methods and nothing seems to work
1) I tryed this one : http://forum.xda-developers.com/showthread.php?t=754669
2) http://forum.xda-developers.com/showthread.php?t=754020 and this one get to step 5 and and no device found I dont know but i cant do any thing if adb dont find the phone
and "adb loob.bat" method I dont know why nothing works it runs the loop i do the recovery and i get a black screen with a pic of a phone with a red triangle and a ! in the middle and the computer dont find the device
Please help thanks
First of all you should have posted your question here: http://forum.xda-developers.com/showthread.php?t=754020
Secondly, if you need it more spelled out, try this: http://forum.xda-developers.com/showthread.php?t=754020
Whatever you do read and make sure you have everything installed, sauch as the SDK, as well as the files necessary placed in the tools folder of the SDK to make it easier to push the files.
ok....have you rooted a Slide before? When you first boot into recovery you get a screen with a phone and a red triangle. Hold down your volume up button and power button at the same time and it should get you to the stock recovery. From there you need to choose Apply sdcard: update.zip. From there if you have done the root process correctly it should boot up into clockwork recovery.
Not sure if you made it that far if your device isn't recognized by adb.
Hope this helps and please post in the correct section next tim. Things like this go in Q&A

Can't get into Recovery

Hi I'm new to the mytouch slide family coming from a Motorola Defy and I'm having a hard time going into the recovery mode. Everytime I try get the red triangle warning. I've watched videos, read ROM bible and other post and still no luck. My slide is rooted by VISIOnary Temproot but with root at boot selected. I've been at this for 3 days trying not to bother anyone on the forum for a solution but now I need help!!!! Also I have ROM Manager and loaded Clockwork Recovery through ROM Manager.
Thanks-
Under ROM manager the 2nd option says reboot into recovery. Im pretty sure you tried that right? You can also get to this by turning off the phone and hold the vol down button and press power.
Oops. then select recovery
hoped this helped

Thanks for the quick reply but yes I've done the the power button with the down vol button and once I select recovery I get the same outcome (Red Triangle). I've even selected the boot into recovery from ROM Manager and the same thing happens (Red Triangle).
Sorry i couldn't be of any help. I did a quick search on yahoo and found this. Seems you aren't alone. Maybe you'll find what you need here.

Ive never heard of that root method. Are you sure youre rooted? You did say you used a temp root method. Every time you power down youre probably breaking root. First, download an app that needs root, like titanium backup. If it fails to load, you dont have root and that will be why you get a red triangle everytime. I would try rooting using a full proof way listed in the development section. Also, i dont use rom manager but i've heard of issues using that to get recovery.

VISIONary is used to temp root the G2. With VISIONary you can select to temp root your phone on boot, so that's what I selected.I tried it on my slide and it worked. May I ask what method you use? I will try the full proof way.
Thanks-
I cant give you a link since im not at a computer, but its called " [UTIL] New Root Method as of 8/13! -> UPDATED 12/30 for NOOBS! <- " and its stickied in the development section. I used this the second time i rooted my phone (decided to update with tmobile's ota and it broke my first root).

I think I may have found the solution to my problem but I'm looking for the HTCsync.zip that I cannot find. If somebody know where I could find please let me know.

Htc sync? What would you need that for. As long as you phone is visible to the computer you shouldnt need htc sync. I know i have never used it
Sent from my T-Mobile myTouch 3G Slide using XDA App
at the red triangle screen you push vol up + power I believe -- can't remember exactly and no longer have stock recovery to check with. But it is just another button combination.
HTH
Temp root apps don't root your phone, regardless of boot settings. You need to have the eng build flashed through hboot to be able to get into a recovery that will flash self signed zips such as clockwork. No matter what you do, without fully rooting using a method in the development section, you will not be able to flash clockwork or any custom rom. Temp root only allows you to run root apps inside of android.

As for that, it's the easiest way of obtaining the ADB drivers for the slide, as the slide is only plug n play as far as mass storage, not its adb interface. I'm sure there are other methods, but installing HTC sync is the easiest.
Need help!!! Recovery
I have succesfully root my girlfriends slide and s-off. but i tried to flash cwm 2.5 thru fastboot and now cannot get into recovery neither factory with triangle or cwm. How do i fix this or will i have to unroot bascially and start over to get the recovery .img again? Also, who can help with permanently flashing cw recovery so that i do not have to use the update.zip method.?

Did you try to fastboot flash the update.zip? That's not good, you should've flashed the cw2.5 .img file. No, you don't have to reroot or res-off, but download the .img file for the latest clockwork recovery on koush's website, for our device. Then, on your computer, while in fastboot mode and plugged into usb, type
fastboot flash recovery filename.img
obviously replacing filename.img with the actual file name/location.
Please help me figure this out...
I also cannot get into recovery mode. Here's my story:
I have a rooted (Supersonic EVT2-2 SHIP S-OFF; HBOOT-0.93.0000) EVO (I know that this is a MyTouch thread, but I couldn't find any similar issues at the EVO thread) that I'm running Warm 2.2 RLS 4 on. I have it set up the way that I wanted and it is running perfect (enough for me).
Yesterday, I caught a glimpse of the MIUI ROM that has an iPhone theme so I wanted to try it out. So, I used Titanium to back up my apps and data to my SD card (8GB with 3GB open). Then, I went to ROM Manager to back up my ROM. I saw that there was an update for the ClockworkMod Recovery so flashed it up to 3.0.0.5. Then I went to Backup Current ROM, kept the suggested name, and hit OK. After a few seconds, the Splash Screen briefly shows, the phone buzzes and then I'm on the initial Bootloader menu screen (with the three Androids at the bottom).
I highlight Bootloader, then I hit the Power button to go to the next set of menus, and the phone does it's checks. After the checks, I push the Volume Down button to go to Recovery, then hit the Power button. The splash screen (white HTC EVO 4G) shows again, the phone buzzes, and I'm back at the initial Bootloader screen.
Whether I use the Quick Boot app, the ROM Manager app, or the Power and Volume Down method, I cannot get past the Bootloader screen to get into Recovery. All I get is Splash, buzz, then the initial Bootloader. Warm 2.2 RLS4 is a nice stable ROM, but I am starting to feel limited, which is why I rooted the phone a few months ago.
Could someone PLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEZZZZSSSSSSEEEEE help me with this? I am far from a comp engineer, but I can follow instructions pretty well.
Thanks a million!
njgoodfella2199: You're really going to be better off asking in the EVO forums. Good luck!
Yeah, we don't know much about the evo or how it works compared to our gsm phones. The way rom manager updates it may be different. You might be able to use the same solution, find the img file of the latest clockwork and fastboot flash it, but ask on the evo q&a.

[Q] OMG - can't open recovery cache on evo

HI - I pray that some can help me resolve my issues. I had to return my phone to sprint for another, this morning I received my new phone and started the recovery process unfortuanely in the middle of it i remember that did not back up my orginal system. Now I have this error "can't open recovery cache" when I attemt to enter in to rooting steps. it aborts on each try. Can some pleaseover me some advise on how I can gain access to my recovery rom so I can complete my rooting process?
If you're trying to restore the backup of your old phone, I HIGHLY don't recommend it.
Can you just not get into recovery?
No Sir I am not, I have no way of gaining access to the recovery system, my phone is functional but I have no way to go into recovery program. I have made a terrible mistake, once I hold the volume button down and attempt to enter hboot it simple locks with the 2-phased dark battery with the big red triangle.
this is the message i get
E:CAN't open /cahe/revoery/comand
---Install from sdcard
Finding update cae...
Opening updae packge...
Verying update package.
E:failed to open /sdcard/update.zip (No such file or directory)
E:signature verification failed
Installation aborted.
That's the entire message
Any help you can offer will be greatly appreciated
Lawlz, no need for sir.
I don't feel like re-uploading the file, but second the second post here > http://forum.xda-developers.com/showthread.php?t=1062442
Place the file on your sdcard, as it is, not renamed, not extracted, ect. Boot into the bootloader, it'll scan, apply update, reboot, reboot into recovery, and you'll be on amon_ra 2.3.
The ! is you trying to get into recovery, but you're on stock recovery, which is no recovery. And you are rooted, s-off?
Do you have root access in your rom? You can try installing a recovery image from ROM manager or find the AmonRa thread on here and flashing the PC36IMG.zip from that thread from within hboot.
teh roxxorz beat me to it...
I have attempt to use the recovery manager - it force closes
I have attempt to use the terminal manager - commands not recongized
I will attempt to upload the link provided and let you know
Aye aye cappy, we'll be lurking.
Sniff, sniff nothing still the same errors
Well no luck, I have purchased the rom manager- it forecloses, I have downloaded, installed and rebooted to bootloader no luck, I have tryed everything i know which is very little. I guess I should consider my lucky that I have a funtional phone, but I will have no access to the recovery mode so i can root it. sigh....
To answer your previous questions
The ! is you trying to get into recovery - Yes that is when i get the error
, but you're on stock recovery, which is no recovery.
And you are rooted, s-off? - No I not rooted yet
I was trying root my new phone when i got myself into this mess,

What method of rooting were you using, and which recovery did you try flashing? As teh roxxorz asked, your hboot is s off right? It sounds like your best bet will be to run an RUU and start over again.

Make sure usb debugging is enabled on your phone, settings > applications > development
Then connect the phone to the pc in charge on, run unrevoked, and you'll be good to go.

That means you have no recovery, and you have no recovery because you aren't rooted. if you follow the instructions I posted above, you'll be good.
Sigh... I was in the process of performing this when I got into trouble, I have the andriod bootloader install, I power down and reboot using volume down key and power, once there I allow the system to perform system check then I select hboot, I have inserted usb cord once this process start and directily run unvoked3. What occurs then is it is not recongizing my phone for some reason and just sits there in limbo for 15 to 20 minutes. I have also unistalled htc sync, cleanded files, and reboot 3 times. I will continue and maybe i will get lucky

You need to turn the phone on, normally, boot into the phone, then connect the phone in charge only, do that, and run it again.

Noob time

Oki.. time to toss in the towel and be a cowering noobster...
I have a Desire HD. I had it fully updated with HTC's ROM. BUt I got tired and desided to root my phone....
So I continued to downgrade it, and got it ser to radio-off by following some easy steps some finnish guy posted here. Cudos to you my friend, and where is that damn thank you button.... ut I got the phone to build 1.32 something and the $ goes # when I do su in a shell....
Got Clockwork flashes to newest version. And desided to download the newest version of Cyanogenmod, though not the Nightly Build. It downloads, and asks if I want to rebot phone to flash it... I want to do that, so yes please.
Then my frustration sets in. I get this red triangle with a exclamation mark on top of it. press volup and power, and I get a manu. Juts before I get the menu I get an Error. E:Can't open /cache/recovery/command. ANd if I try to do the "Apply sdcard:update.zip" I get a validation error check.
I have tried to find out where I turn off the validation, but no luck there...
And now for my question... since this is a question forum.
Have I missed something? And in case of yes, what might that be? and WHat can be done to make it happend.
In advance.. thanks. ANd sorry if I bored you with the trivial facts of my problem...

How did you flash clockworkmod recovery? I'd try flashing it again.
Bear in mind if you select sdcard:update.zip
You have to rename the downloaded cyanogen zip to 'update.zip' and put it in the root if the SD. Or select choose zip from the cwm menu instead of renaming it.

The red triangle is the stock recovery, try reflashing recovery via ROM manager or fastboot and see how you get on
Thanks. Flashing clockwork from rom manager worked when I did it the 5th time or so. Anyways, I am here now in custom rom. And works great.
Thanks for the tips.
