[Q] ROM Manager Signature Verification Failure

A few weeks ago I flashed the Cognition V2.2 ROM and everything was fine until it started getting twitchy a few days ago. I tried to use the ROM Manager to restore the backup that was created during the flash but I keep getting the same error message and the phone does not seem to go into the Clockwork Mod Recovery but stays in the Android system recovery. The message says that the whole-file signature has failed to verify and that the installation was aborted. Does anyone have any idea how I can get my phone back to normal?

Common knowledge that the version of Cognition you are running is not supported by ROM Manager, it is 3e recovery and Clockwork needs 2e. You can update to the newer Cognition which has 2e recovery. I recommend you read the facts sheet befor flashing, the method you should use is Odin one click back to stock http://forum.xda-developers.com/showthread.php?t=731989, then master clear so that nothing is lingering from your previous setup, backup everything from your internal storage to your pc first, this will wipe everything from your internal, replace it after you finish Master clear. you should only replace the update.zip, ClockworkMod and your music, photo's and that stuff. Backup your apps using Titanium Backup.
Here's the link for the new Cognition http://forum.xda-developers.com/showthread.php?t=786532

So I tried what you recommended and got my phone back to the stock condition but I'm still not able to use ROM manager or flash another ROM. After I root the phone I install ROM Manager, flash it to the current edition and then try to reboot into recovery but when it gets to recovery it gives the following error message...
--Installing from package...
Finding update package...
Opening update package...
E:Can't open /cache/update.zip
(bad)
Installation aborted
Also the header of the screen states that I am in Android system recovery <2e>. If I am not mistaken, shouldn't I be in recovery <3e>? If so how do I get there? I've tried flashing the stock Kernel but that didn't work and I even installed the internal betas correctly but no cigar.

did you really read Rhi's post?
in order to use rom manager (clockwork mod) you must be using 2e!

Touche, but the error still remains. Does anyone have any positive ideas? Like I stated before, I still cannot put my phone into clockwork mod recovery.

so put it in download mode, and use ODIN one click back to stock...then leave it the hell alone....

Like I said, I've already used Odin. Everything is back to stock except for the Kernel and a stock kernel install with Odin doesn't seem to work. Odin says that the install passed but nothing changes on the phone itself. All things considered, the phone is stock but not capable of going into Clockwork Mod recovery.

When you go into stock recovery now is it version 2e or 3e?

if you used the one click back to stock then you are on the stock kernel.....what makes you think you are not on the stock kernel?

The recovery is 2e
I believe that the kernel is not stock because when I look at the phone information it says that the kernel is
2.6.29

I'm not sure that it is stock or not but my gut tells me that it isn't.

Rom manager will work just fine with 2e recovery. Just delete any update.zip files you have in your home directory - then open rom manager and reflash clockworkmod the cappy - then you should be good to go.
As for whether or not that is the stock kernel I am not sure, but how can you tell just by looking at it if you don't know which kernel is the stock one?

I've mounted my internal and external sd cards and removed any updates but it still gives the same error. After I used the odin one-click to flash the stock rom I used the master clear as recommended. Now, if I am not mistaken, shouldn't that erase all of my user data? I reinstalled my espn app so I could follow my football team and the app still remembered my preferences and favorites. This makes me think that the master clear did not finish the job. Thoughts?

Master clear should've done that. If you are restoring your apps and settings using Titanium Backup then you are restoring user data which you should not do.
When you Master Clear is your device on and on the home screen, it needs to be. Don't Master Clear in Recovery mode or Download mode or it does nothing. Also you need to have debugging on.
2.6.29

That is the stock kernel. Just so you know if you are running stock with root you can simply place the update.zip from the Clockwork folder, you should have backed up before flashing and Master clear, back into your internal. ClockworkMod does fail on first attempt to flash sometimes, it happenned to me the first time I flashed it, the second time worked like a charm. Are you rooted? You need root to use ROM Manager and debugging should be on.

After you deleted the update.zip then opened rom manager and flashed clockworkmod it should of put a new update.zip on your phone in your home directory - can you confirm that this is the case?
Also you may not have had a successful master clear - you may want to do it again then redo odin3 one click. Also if I am remembering correctly I believe you have the option to clear cache or user data or both in stock recovery you may want to try that as well.

It all works now. The issue was with the master clear. I guess that I did try to run it in the download mode. Thanks a million guys, i really appreciate it.

Maybe I was a bit premature on that. ROM Manager works beautifully but I cannot install updates or flash a custom ROM. The Manager was able to backup the system correctly and enter clockwork mod recovery but it cannot install the update. If the update is on the internal SD it says that...
E:Can't open /sdcard/update.zip
(bad)
and if the update is on the external SD it says that there is no such file or directory. Am I doing it wrong or is there still an underlying issue?

/sdcard/update.zip should only boot into clockwork recovery from stock recovery or boot to stock recovery from clockwork recovery if you flashed clockworkmod correctly from rom manager - and so long as you are not renaming any other files as update.zip after you flash clockworkmod recovery.
Which custom rom are you attempting to install?

I got it. The zip file was corrupted. Now, should I be able to boot into normal clockwork mod recovery with the Cognition 2.2 Beta 7 cuz when I try clockwork recovery it boots into normal recovery? I'm still a little hazy about all this.

When you first boot into recovery it should be stock recovery. While in stock recovery when you select reinstall packages it will reboot into clockwork recovery - if you flashed clockworkmod recovery correctly from rom manager and it put the appropriate update.zip into your home directory.
And just to note: don't be renaming any files as update.zip if you are using clockwork recovery to flash something.

Can't access recovery

Hi there, after rooting my phone with the "DoomLord's via Zergrush Exploit" , and after installing rom manager and flashing clockworkmod. I just can't access it.
If I load into the bootloader and click recovery, I get an image with a ! sign and a picture of an android, the same happens when I load recovery through rom manager. I have flashed the recovery twice now and my phone's just not having it. My phone works no problem, I just dont understand it
All I want to do is to make a backup and install a custom rom
Am I doing somthing wrong?
(Yes, my bootloader is locked BTW)

Very simple - you didn't flash the recovery properly, so you're getting to stock recovery.

Yup like Jack_R1 stated, the flash didn't stick or you didn't do it right.
Open Rom Manager, at the top it will tell you what recovery you have.
Does it show anything?
You could also try adb if you have that setup
http://wiki.cyanogenmod.com/wiki/Nexus_One:_Full_Update_Guide#Installing_a_Custom_Recovery_Image
You could even install it via terminal on your phone
Heck try this recovery, it's good
http://forum.xda-developers.com/showthread.php?t=1291970

Try THIS. Install the application and it will install the best recovery

Rom manager tells me that i have clockworkmod 5.0.2.0
I'll try installing the recovery through terminal when i get back to my pc
Sent from my Nexus One using XDA App
EDIT: Having seen the other recovery you've stated, i'll try and install that.
Also, does it matter about which version of android i'm running? could that result of a bad install of the recovery through clockworkmod?
Its 2.3.4 stock rom if anyone's intrested
FINAL EDIT:
Thank you!
4EXT flashed perfectly, after using the app to reboot into the bootloader, it loaded up that. Many thanks!

[Q] rom manager recovery mode

Hi guys,
posting here as i've tried searching and nothing comes up (anything that does has out dated download links or just doesnt apply)
Problem: after rooting my phone when i try to use rom manager, nothing happens. I've bout CWM touch, I've downloaded the normal CWM but when i try to either load cyanogen from the zip on my sd card it does nothing, it prompts me to back up, wipe etc but then when it says it will boot to recovery nothing happens. Also tried other apps to reboot and none of them work
any advice on this?
I've seen a cmd prompt set of instructions for Superoneclick, but im lost as to the getting to the directory through cmd tool.
any help would be greatly appreciated

Hi , if you have CWM touch, install QtADB on your computer => http://qtadb.wordpress.com/download/
reboot recovery from menu
or install android sdk and in a command prompt : adb reboot recovery
or at reboot OB, press G-key

Did you flashed recovery? First option in rom manager.
Trolling in the deep

yep clicked the first option, the prompt for the device comes up, i hit it, then the bar loads... then "succes".
then when i try to install from SD card nothing happens
Thankyou YkZ_1967 !!! However I installed qtADB and got reboot recovery, but it just reset the phone. Any ideas?

that's depend what you want to do, if you install custom rom, reboot in recovery, wipe data/cache / dalvik , then install zip from sdcard and choose your rom, then after success flash, reboot now.

I want to install cyanogen but when i try to load from sd card in rom manager it wont go into boot recovery.
when i managed to get it to boot recovery in the way you suggested it only reset the phone.
I feel like i'm missing something, did not think it would be this difficult

That means actually no cwm recovery installed yet so it will reset your phone everytime you want to enter recovery mode. This is the best thing you should do : reroot your phone like in this guide http://forum.xda-developers.com/showthread.php?t=1487105. It will automatically installing cwm recovery touch. After that, you can go to recovery mode by using quick boot (download it from playstore). Therefor, you can start flashing roms, but remember don't use rom manager, coz it wont detect your cwm recovery touch and forcing you to flash the non-touch cwm recovery.

follow the method with smartflashtools and v20.x patched with cwm touch by SnegovikRZN , then you have OB rooted with CWM Touch, you will be able to install CM7 and unbrick your phone.

Thank you thank you thank you!!!!
Got it to work that way all i had to do was flash that then clear data/wipe cache/wipe dalvik and then load from sd card and it works! very happy now

after you try to install zip from SD card and fails, check to see if it shows: error can't mount /sdcard. or something like that. ???
if it syas so. try a different recovery like TWRP, i was having a problem, similar to what you describe, an hour ago while rooting and flashing my mother's in law OB, i flashed the CWMT recovery and for some reason it couldn't load the ZIP from SD and it showed this error, so i flashed TWRP recovery and then it was fine, i manage to flash marvel rom and all was good.
hope it helps.

you are right, but i had a problem, the CWM was flash and ob went into CWM recovery mode, but for some reason it stated an error that it cannot mount /sdcard, so i tried via recovery menu to mount sd card, didnt work, then i tried again to flash a different version of CWM, same error, then i went and flshed TWRP and it worked.
i wonder if its a specific OB bug, bcoz this problem happen on my mother in law OB and on my OB it was rooting and flashing just fine, exactly like the guide.

Is Galaxy S advance supported with Rom Manager? If Not, other ways to change ROMs?

Hello,
I have recently purchased a Galaxy S Advance phone, and I am quite new to the android os.
I have read already many guides and forums about the whole process of rooting / flashing etc, so I have some knowledge of the terminology.
I already have a rooted phone with GB on it (yes, I know JB is about to come out officially ) and I wanted to change some of the UI elements.
I installed the rom manager app by koush, but yet to use it because I saw that in the past that the phone wasn't supported.
My question is: Does ROM Manager support this phone? Can I go ahead and flash CWM on it from the rom manager app, and then use it to flash other roms?
If not, which is the best solution to backup and replace roms? ODIN?
Thanks,

I think it is not working. It is not supported. Way we install custom ROMs: download ROM zip, transfer to SD, then go to recovery and install it from there.

I checked TWRP supported devices list (tried to link it but forum wont allow new users to link ) and I don't see the galaxy advance S on their list either.
Is there a special mod version for this device?
And another question, if installed, will this wipe the current phone data or just the recovery loader? Since I want to backup my current ROM (+ contacts, settings etc.) before doing anything sketchy...

You have GB? Look here.
On I9070 recovery is on the same partition as kernel. So it can't be installed separatly. It is ported. You need to install this kernel, or CoCore. If you install with Odin - you will increase binary counter. For installation with ADB shell, or Terminal emulator (app from market) you need root - and it will not increase bc.

So I am guessing I will use the dd command line way since it doesn't increase the binary counter (why would we want to do that ).
Is it possible to backup the current ROM before flashing it with the TWRP modified ROM?
And another thing, since I will be using other ROMs, how can i add the TWRP recovery loader to them (you said that the recovery is on the same partition as the kernel, making me believe that each ROM I load will need to have TWRP on it)?

No, only JetMOD have embendend kernel too. And it have TWRP.
Hm, another thing. You better use non binary counter increaing root method. But it need you to flash whole firmware with Odin. And maybe you loose data. But if you do not do factory reset - it will be ok.

Sorry, I didn't understand your last post.

If you want to get TWRP with dd command you need to root your phone first.
There are 2 root methods. One that increase binary counter, and one that do not..
With one that do not increase - you need to flash whole firmware with Odin. And by doing that you might need to do factory reset. That will cause your data and app delete. You can try to boot, maybe it will be ok.

Oh, I already said I have a rooted device, so this wont be an issue.
What I asked was:
1) If I can backup my current ROM before installing the TWRP ROM you linked (in case something goes wrong).
2) When I install other modified ROMs, will they override the TWRP I installed, or just change the kernel system leaving TWRP in the recovery?

Didn't pay attention.
You have backup option in TWRP, and you can restore it.
Custom roms do not have connection with kernel, just JetMod who do have kernel with TWRP too.
P.S. lol you confuse me. TWRP is kernel related, nothing to do with ROM.
When you want stock kernel back, just flash your firmware from sammobile.com.
So you need to change kernel to get TWRP. And with TWRP you do backup of system.

Hmmmm, now I am a little confused.
Since I don't want to touch the kernel (yet), all I want to do is change the ROM (as in UI changes etc...).
I wanted to backup my current ROM and then load other ROMS.
I started off with ROM Manager because it seemed to answer what I wanted to do, but as you said ROM Manager doesn't support this phone and we went from there to TWRP.
Since I now get that TWRP is kernel related only and not ROM management, what would you advise right now for:
1) Backing up the current ROM
2) Loading other ROMs to the device?

You can do that only with TWRP.
And did you read ROM manager description?
* Flash your recovery to the latest and greatest ClockworkMod recovery.

For ROM manager you need custom recovery. And for I9070 that is embended in kernel. Full stop.
And it is connected to CWM, not to TWRP. We do not have CWM for Android 2.3.6. ported.
P.S. So to close this:
- You can't do any backup, installation of ROMs without custom recovery (in our case TWRP) on our phone.
- Custom recovery couldn't be installed separatly - it is embended inside kernel file - and has nothing to do with ROM.
It is clear now?

I think I got you now
1) CWM doesn't work on my phone because the recovery is attached to the kernel.
2) In order for me to backup my ROM I need to install the kernel with TWRP embedded (the one you linked me).
3) I also can't backup my current kernel without TWRP so in order for me to have TWRP I will be doing #2 without any backup? I am guessing this is the part where bricking has a chance of occurrence?

CWM = TWRP
Both are custom recoveryes. Not the same, but same purpose.
1) Our phone have same partition for kernel and recovery. So we can't install it separatly
2) You can backup kernel, but you will need Terminal emulator, and similiar command like instalation of other kernel
Code:
$ su
# dd if=/dev/block/mmcblk0p15 of=/sdcard/boot.bin
# reboot
This will backup your stock kernel on your sdcard. You can install it later this way (ofcourse if boot.bin file is on your sd)
Code:
$ su
# dd if=/sdcard/boot.bin of=/dev/block/mmcblk0p15
# reboot
You always can flash your stock kernel, Download mode do not have anything to do with kernel and recovery partition.
If this is little hard for you, just install custom kernel with TWRP. Or do not do anything. :laugh:
P.S. Trust me, you can't hard brick device with installing kernel. I am tester, and I flashed at least 10 non booting kernels, and 50+ booting ones.

I do trust you, just trying to get an understanding of how the things work on these devices.
So I now understand the backing up and flashing commands (I would like to know how you knew the mmcblk0p15 was the kernel partition for this phone), so where does the "Download mode" come in handy if u can flash directly from a terminal window?
If for some reason the flash wasn't successful, can you enter download mode and restore the backup you created?

Most likely you will have to flash whole firmware if something goes wrong. I told you what I know.
And if you can go in TWRP recovery, it can restore krenel with other things you backed up. And you can flash new kernel in TWRP too.
Somewhere is written what partition is for what. I do not know that. And developers told us what partition is for kernel and recovery.
I do not think that that thing with restoring downlaod mode will work. Newer tried or heard of it.
I tried to explain you, but maybe I was little confusing. :angel: My english is not great, and I didn't provide 1, 2, 3... steps explanation. Like I throw everything to you. :laugh::laugh::laugh:

:laugh: More or less I understand you :laugh:
So to sum up:
1) Create a backup of the current kernel
2) Flash Stock Kernel + TWRP
if all goes well....
3) Create full phone phone backup from TWRP
4) flash custom ROMs (or kernels) with TWRP
Hows that?

That is ok.
And you backup old kernel that you can easy go back to stock one. Without flashing whole firmware, when you want stock. Like you want to go to service for warranty or something like that...

[Q] Stuck at CM recovery after accepting newest official software update

Hi, device is rooted, and clockworkmod recovery 6.0.4.5 installed.
ROM is JB, the official update from LG. Today device reported there is an update to the installed firmware.
I rebooted in CM recovery, took a nandroid backup, booted, and accepted to download the official update to my official JB rom. After downloading I was asked to reboot (in order to install), and the phone reboots to the CM recovery.
From there I don't know what to do. I have tried rebooting, but again find myself to the CM recovery. I have tried "reboot to bootloader" and get stuck at the LG boot screen logo with the message "Now Ready!" in tiny white letters on the upper left corner.
I would try "install zip" but I don't know where the downloaded update is (if it even is in an acceptable zip format)
Phone isn't bricked, I guess I can always restore from the recently taken backup, but I really would like to know if there is a way to install this update.
Thank you

You're right, but you know, sometimes you just can't nail the right keywords especially if its not your native language. I searched, but obviously not good enough.

Sadly, this seems to be the case.. bummer.
Thanks everyone

Not even my nandroid backup can help me get to where I was before? So much for nandroid being the ultimate backup, a "snapshot image" of the device...
So, what if, I use CM recovery to install a custom rom, and then restore from my nandroid backup (being the official JB) ?

Flash with kdz flasher original ROM then flash cwm you can put back your backup. I think the problem starts that the update pushes something in the boot section that is expecting an other (read original) recovery . when you installed cwm it boots up cwm so that's why an nandroid backup doesn't work I think ( to be honest I'm not 100% sure this is correct)

I can't even flash cyanogenmod???
I downloaded latest stable build, copied it to sd card, selected it from the CM recovery ("install zip"), installed fine, reboot, still stuck at CM recovery!!!
What gives?

Have you yet followed the advice and installed the KDZ?

Trying to avoid that, as it seems too much work for a phone that was working fine, and stuck to recovery due to some silly boot flag or something.
Saw it as a chance to try cyanogenmod. But it seems having CM recovery and the cyanogenmod rom on the sd card won't cut it! Talk about failure..

I don't think you will have a choice. If you created the nandroid backup on your SD card then you aren't going to lose it, so just flash the KDZ, root again and install your backup, or accept the LG update and rebuild all your software again.

Yes, one thing is for sure. I had to install the KDZ to be able to proceed with anything..
It's just funny having a working CWM recovery and a cyanogen rom on the device and after flashing it, still not having a device that boots. A "recovery"/flash tool, should be able to "recover" from such a situation..

You can't blame the recovery. It is clearly stated many, many times that you should never attempt an official OTA update with a non-standard (rooted or recovery installed) device. On other devices you could even hard-brick AFAIK, so consider yourself lucky that you only had to reflash a KDZ and start again.

For restoring stock rom use this: http://forum.xda-developers.com/showthread.php?t=2682146 I can confirm it works and it is (very) easy.

Yes that's what I used and I also confirm it works and is very easy.
