"E:can't open /cache/recovery/command", means???

I'm enjoying the new roms that are coming out, each one is better than the last, and I've tried just about every one of them. That being said I am still having a few problems with the g1. When I boot using (home+power) I see this at the top of the screen "E:can't open /cache/recovery/command" I've tried updating to cyanogens newest recovery console and it didn't change anything that I could tell, I can't even alt+X to get a prompt, this text at the top could be the reason why. I'm sure I have messed something up but honestly after 2 days of searching I am still no better off than I was before. Also, I cannot get my sd card to work properly. I've tried every way on earth to format the sd card to attempt to get 3 partitions. When I do this, I either cannot install update.zip to the fat32 part, due to the recovery screen not seeing anything on the card ("update.zip not found") or I end up boot-looping after the HERO screen. I'd like someone to help me start this over again. I've used all the different roms out there, I just want to get my SD card properly formatted so my HERO rom will use the swapfile and ext2/3 the right way. I'm not sure what I'm doing wrong, I've followed the "step by step" guides in this forum and to my knowledge I've done everything right a few times over. I used paragon to attempt to set up the sd card, and I was using the correct radio/spl for each rom I attempted to use. It also might help if I mentioned after re-installing the Cyanogen's recovery img, I saw no change in the (home+power) screen. If you need more details from me PLEASE don't hesitate to ask me, I just want to get my phone set up the right way so I can install all my apps and not have to stay in the habit of flashing my phone 5+/- times per day which is cool but getting old fast! So please help >.<

You need to reformat your SD card. That message means nothing. I had that before.

I have reformat the card over ten times now. I've tried using the paragon method, did it exactly as the guide said, I got boot loop and had to reformat the card back to fat 32 so i could even boot to hero. I still cannot use alt+x to access anything from the recovery screen either.

Do you still have root?

do you have access to ADB?

Yes I still have root, and I am currently running Soulife Roger's 2.8 if that makes a difference. I'm not sure what ADB means is that something I run in terminal?

3. Download the recover_testkeys.img
http://files.lucidrem.us/_fd.php?file=jf/ROOT/recovery_testkeys.img
4. Copy recovery_testkeys.img to SD FAT32
14. Type cat /sdcard/recovery_testkeys.img > /data/local/recovery.img[enter]
15. Type cat /sdcard/recovery_testkeys.img > /system/recovery.img[enter]
16. Type flash_image recovery /system/recovery.img[enter]
once you do this .. try to reboot .. let me know if you're good to go

I tried the "cat /sdcard/recovery_testkeys.img > /system/recovery.img" and I got this message " cannot create /system/recovery.img : read only file system "

You must type "mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system" no quotes. Before the cat commands.

Tried using that command first and using those 3 commands again. Nothing happened other than when I load into recovery menu, I see Android recovery menu, test keys, then I get the same E:can't open /cache/recovery/command error as I was before. I'm still having SD card issues too. I can't seem to get this to work right, no matter how many times i read a "how to do xxxx"

The "E:can't open..." is referring to the Nandroid backup- I had the same problem too and everyone thought I was crazy. This may be preventing you from updating to the cyanogen recovery.
When I rooted my phone I went directly to JF1.5 which does not have nandroid in it. To solve it, I flashed the previous JF (1.43?) and that went away.
Give that a try and then flash the cyanogen recovery. Good luck.

I had the the same problem mate! here is what I did to fix it....
1....format card to fat 32 (make sure you dont have any other partitions on your card!)
2....go here and download the "update.zip" version http://forum.xda-developers.com/showthread.php?t=523558
3....rename and flash the file in the normal way!
4....enjoy!
p.s. make sure you sdcard is freshly formatted and as only a single fat32 partition.

attempted that last suggestion twice before I posted here that it unfortunately didn't solve the issue I still get the same E:can't open /cache/recovery/command error i've been getting and cannot install cyanogen's recovery image. Is there anything else I could try? Surely there is a reason for all this trouble I've been having with the SD card partitioning working with the ROM, and being unable to use cyanogen's recov.

Does it go back to the command prompt or error?

I'm pretty sure that the error message I've been getting is the only reason I'm having these issues. IF I could use cyanogen's recovery, I could follow the exact guidelines here http://forum.xda-developers.com/showthread.php?t=533731
Since I cannot do the " How to install custom ROM (With full wipe)" part of the guide, I think that is where my issues with SD partitions working properly within the ROM.
Again thank you for the help, I don't have much black hair left, the gray is running wild

^ It went back to the command prompt without an error, and this time after typing all three lines of code, and rebooting the phone to check the recovery menu, the error was still there as if I had done nothing.

how were you able to update to cyanogen's recovery if you can't get into recovery in the first place? or did i read that wrong?

When I flash the Cyanogen's recovery, its as if it did nothing, I'm assuming from what I read it would add more functions to the screen or it would be obvious that it did something. I thought that if that had flashed correctly I would be able to use alt+X to open a prompt. I could be completely misunderstanding what it is supposed to do, but I don't know I thought I was more sure of what I read
I thought my error message at the top of the screen (after home+power) was what was preventing me from installing the recovery.

Ok I tried flashing an older version of the JF1.42 and my recovery error has been solved. Thank you for all your help!! Would I need to flash to something else If I wanted to run the latest and greatest hero rom? Either way what would you suggest I do next?

HELP!! installed CM 4.0.3.1 with move cache..NO SD!

hey guys i just updated to CM 4.0.3.1 and it automatically installed move cache to sd, i also accidently installed teds hero theme, not knowing it wasnt ready for 4.0.3 yet, but now my phone cant read my sd card, therefore i cant mount/unmount it , could this be from the "move cache to sd" app? any help is appreciated, thanks guys!

Did you have your card partitioned with ext2/ext3/ext4? If you didn't then apps2sd won't work. And you can always mount your sd card thru adb.

Just partition your sd card with your fat32, ext2/ext3/ext4 (I would do ext3), and linux-swap then reflash the rom.

i dont know how, and my sd card doesnt even show up on my phone at all

btw im using my 1gb card that came with my phone

Do you have a card reader?

nope im suggesting my card is toasted or i have to do a wipe?

try booting into recovery, drop into the recovery console and type
ums_enable while your phone is plugged up to your computer. if that works, when you are done type ums_disable. that should allow you to mount your card in recovery

either way, i still dont know how to partition my car....i just want to be able to get it to be read so i can reflash my rom and go back to normal

we all had to start somewhere
do you have adb? if so just type adb shell reboot recovery
if not, then while stuck at the android screen press send, menu and call to reboot then hold home to boot into recovery.
once in recovery, does it have a picture of a green android, or what is the background of?

CM 4.2.4 upgrade issue

Hi team,
Having some trouble rooting my g1 and upgrading to CM 4.2.4
I have been following a tutorial from here: http://androidandme.com/2009/08/news/how-to-root-a-t-mobile-g1-and-mytouch-3g-android-phone/
... to achieve my goal. Followed all of the steps fine and to a tee. Installed all of the suggested files from the suggested places.
Succesfully upgraded the radio image, then moved onto upgrading the SPL. Ran through and rebooted phone, until the never ending "Formatting Cache" notice came up on the automatic boot into the Recovery Mode.
(FYI: radio and SPL images were from http://code.google.com/p/sapphire-port-dream/)
Moved on to installing CM 4.2.4 after realising that the format was complete... Alt-W then Install from zip. Installed CM. Waited for prompt for completion... pressed reboot... then the boot hangs on the G1 startup screen.
Only way I could get out was to remove the battery. Went through the process again (Alt-W, SPL install, reboot, Alt-W, CM install, reboot, hang) numerous times, all with the same outcome.
Only thing that I can think of that I am doing wrong is pulled straight from CyanogenMod Wiki explanation: "I've noticed on some devices that when you fresh install the first time and you update with the rooted adp package from htc, reboot and then update to latest CM, some people get stuck at the tmobile logo. What I did was install the rooted adp package from htc, reboot and sign in all the way to home screen, then rebooted and installed the latest CM. That should get you past the first screen freeze if it happens to you."
As I am a noob, I have been unable to try this for the following reasons: 1. Where can I find the HTC rooted adp? and 2. How do I get this image onto the SD card when I can't boot in? I have tried without booting and my computer won't let me access via USB...
I was going through the process from factory settings. Is this my problem... Very confusing.
Realise that there are currently two active threads running in this section that are similar... but these guys seem to have done the wrong thing and are trying to right the ship... I can't seem to figure where I've gone wrong.
Thank you in advance for your assistance.

As well: could booting with camera + power get me into the Dreaming.nbh OS to get HTC root OS onto the SD card?

http://developer.htc.com/adp.html
Download the 1.6 recovery image. It is actually the 1.6 Android Dev Phone ROM, flash that via recovery console... then flash the cm update. Make sure you wipe before you start flashing.
As well, do you have your SD card partitioned? It would be a good idea to do that as well. Two ways to do it, manually, or download and update to RA's recovery image 1.2.3:
http://forum.xda-developers.com/showthread.php?t=566669
I would update to that recovery first, use the option to part my SD card, upgrade to ext3, wipe, flash 1.6 recovery, flash cm update, good to go!

Thanks for the quick reply! Very handy info... How do I get the images onto my SD card without being able to boot though?

Do you have another device like a camera, or mp3 player that can take a microsd? If so just hook it up and transfer.. otherwise you may need some additional devices.. I bought an adapter so my sd can plug directly into a usb.. other than those couple options, I haven't any more suggestions to offer ya. If you cant get past the boot screen to mount, I don't see how you can do it through your G1.. there might be some terminal commands you can try to mount to a computer.. but that's beyond me.

You take it out of the phone, while the battery is pulled, put it in an micro SD card reader, plug that into your computer, tada! If you computer doesn't have a slot for the standard SD card adapter, you can get microSD to USB adaptors most everywhere that sells electronics.

Or if you have cyan's recovery installed... you can hold Home+power
go to console, press enter and type
ums_enable
Click to expand...
Click to collapse
and it will mount the sd on your pc.....
put ums_disable to unmount

Sorry to be a noob, but what benefit does partitioning do?

If you have an EXT3 partition, you will have app2sd. If you also have a linux-swap partition, you will be able to have a swap file (in simple terms its like adding more ram)

The ext partition is for apps2sd, and the Linux-swap partition is to give a little extra memory for the ROM.

Thanks for all of your help lads! Up and running. Muchly appreciated!

Urgent help needed :(

I have had my g1 for about a year now and I rooted it a few months ago. I've been trying to update the rom but everytime I try to format the sd card on my pc it says no disk found in drive F. I have tried it on other computers. I tried it via usb and a card reader. When I put update.zip into the root folder it says it cant find it. Please someone help! I need my phone to be amazing again!

Is the card formatted in Fat32?

Yeah its formatted to Fat32

you have to assign the a sd card a drive letter.

assign the sd card a drive letter.

How do I do this?

Well I just assigned it a letter and the same thing happens. I really am stuck.

What are you trying to update from? What update are you trying to apply? What recovery are you using? Do you have a file manager on your phone like androzip? If you can answer some questions, you may have a few workarounds....

You could try doin it with your phone (since you said you're rooted) using recovery
If you're using Cyanogen's recovery there's a good guide on androidandme.com
http://bit.ly/61CXFo
If you're using Amon_Ra's recovery I think it's automated, I've never used it before but from what I understand the you have the option to do it from the recovery menu

I'm currently running cyanogen mod 4.1.11.1 I'm not sure of the recovery image and I am trying to update to the next version of cyanogen. I think it might be a problem with my phone :S I really dont know. I have looked online and nothing seems to work I can put any update onto the sd card but when I try to update on my phone it says the file doesnt exist

it should say what recovery you are using in the recovery screen.
connect to wifi spot, download the new amon ra recovery, and move it from the download folder to the root of the sdcard using androzip (from the market).
follow the steps to flash the new recovery in the amon thread.
the next steps from there are up to you.....you can try to repartion your card using the menu option in recovery and then try to mount your g1 to your computer in the recovery menu. the recovery will allow you to choose what size partitions you want (fat32, ext, and swap) and do all of it for you. very handy.
once you get it to mount to your computer, you're in business.
if you think your card is ok as is, you could always download the htc file and cm4.2.6 directly to your g1, move them from download folder to sd root, wipe everything and flash.
either way, if you run into problems with your card, you maybe without phone until you get a good card.
good luck

Hey thanks for the great replies. Still no luck though I downloaded the amon ra recovery image and did what it said but when on the terminal emulator I type mount -a and it says 'mounting /dev/block/mmcb1k0p2 om /system/sd failed: no such file or directory'

Bump! PLEASE HELP ME

Can't mount SD Card.

Have a 32B. It broke, so I swapped the insides of that one into another G1. The G1 boots into recovery, there's no ROM flashed on the Phone. I tried to mount the SD to PC. It shows that there's a disc connected. But it wont open it. The SD card will mount in my other phones, and connect to the PC via USB, USB dongle, and SD Adapter. I can't flash ROM's via recovery. All i get is this error:
Build : RA-dream-v.1.7.0
E:Can't mount /dev/block/mmcblk0
p1 (or /dev/block/mmcblk0)
(No such file or directory)
E: Can't mount SDCARD:
So I was like meh, I'll flash the ROM via ADB
ADB Isn't working either
just saying "device not found".
Anybody have any clue what this means?

Here's something to try:
Back up all the stuff on your SDCard to your computer using USB.
Unmount the SDCard from the computer.
Go to Settings/SD card, and unmount the card and select format.
(at this point I would turn on your WiFi if you have is to facilitate the faster Rom download your about to to, but it's not necessary)
Go to Rom Manager and select download Rom, and choose the one you want.
If its a cyanogen one, you will be asked to install google apps (gapps), Yes. Backup Current rom, Yes
When asked to reboot to install the Rom, Yes
If all this works out, replace you stuff on to your SDCard
Good luck, and let me know how you make out!

That would work, but my board has no ROM flashed on it. Can't access SD Card in Recovery. Can't push the rom to data with ADB.

Man, here's two way for this situation:
1. (Good) You just updated your radio in a wrong way. Try to do this right
2. (Bad) Your phone now is just a brick. You can use it like a hammer
Hope, your way is first. Try to reinstall radio, bootloader etc.

my g1 doesnt detect memory card....but dats because the thing that reads the sd card is loose but if i press on the bottom of the phone it reads...you could try that..but again you will have to keep on pressing on the bottom so that it flashes the entire rom works for me.
one question though how do you flash a rom via adb???

I know for a fact it's not bricked. It's just I took the board from my 1st G1, 2708+ and Everthing. Worked perfectly. Then i just put it inside a "New" G1 b/c that on didn't boot. The G1 boot's into Recovery, just wont access SD card. I hate my iPhone Xo that's the only phone I currently have. Don't let meh use iOS YoY.
I'll post Pic's soon. All I have is a ****ty 3G, and it's not on iOS so no autofocus. Unless a blurry cam pic can help. Otherwise I'll wait for the wife to get home with the Nokia.

Waiting for pictures!) А тут часом никто русский не затесался?)))
