[Q] Noob rooting and backing up (NAND) SG2 before ROM change - General Questions and Answers

Hi all,
Would appreciate any assistance with this as I'm going back and forth on this topic on the net and hitting dead ends at every turn.
Firstly, I have a Samsung Galaxy S2. It is ROOTED (using S2root). I have installed ROM Manager and Clockworkmod. 4.0.0.15.
I was using these instructions
*URL prevented by forum* but it was on androidpolice.com website -- to get to be able to do a full NAND backup before I screw about with anything. However, I cannot. Whenever I choose to do a full backup from rom manager my phone restarts and I get
Android System Recovery (3e)
4 options not including backup or restore (i.e. reboot, install update from sd,wipe data/factory reset, wipe cache partition )
and at the bottom of the screen
E: Failed to verify whole-file signature
E: signature verification failed
Installation aborted
and won't go any further
I've read forum posts elsewhere on 'toggling verification on/off' but there is no option to do this in any menu, including ROM Manager's even under Advanced. I've seen other posts that show a toggle in the Clockworkmod menu but I never get there - it only restarts in Android System Recovery not Clockworkmod recovery menu.
Does anyone have any sensible suggestions that would help please?
thanks
Mark

Before people can help you, you need to give more information.
What is the model for your phone and is it rooted?
If so, what ROM is it running and what custom recovery do you have?

Ok you can't "apply sdcard:update.zip" because even though you rooted your phone, you don't have a custom recovery. You have the stock recovery image that comes with your phone. This means that every zip you try to "apply" or flash will automatically be checked for a signature (to make sure its a valid update from the manufacturer). Since the ROMs usually don't have signatures, it won't work
Never mind about finding out the ROM. since you have a stock recovery, it looks like you haven't put any custom ROM on it. you are running the stock android OS that came with the phone.
It seems your OS got messed up when you tried to root the phone. The One Click root method you used I believe wasn't fully compatible with your phone. You should have used "Universal Root." Anyway, Give me a day or two. I will see If I can find you an official zip belonging to your manufacturer. THAT you can push back onto your phone and get your OS back and in working order.
Cheers!
P.S: Check if there is an option in recovery mode called "Toggle Signature verification" I doubt it but if there is it would DEFINITELY help you.

I'd recommend changing to CWM recovery via rom manager if you need to toggle verification. Rom manager from the market will flash a recovery for you also.

Here is some dato of my hero:
HERO CVT SHIP S-ON

2. official update.zip can fix your problem.
You can't do anything(but your mobile company can help you)
1. Your mobile company not release any update for your device
2. If USB Debugging is disable
I send my Micromax Mobile on 08 Feb, 2011 and Still no info on my device, Micromax = Poor Quality Support, Wastage of money.
@Micromax - Please close your company.... and move your company to your own country....
I tryed to fix it with every update.zip I found in web by
downloading the zip
rename to update.zip
format sd card
copy update.zip to sd card
start in recovery mode
try to start update
... and get a varification failed error
Has somebody a working update.zip, or can say where can I get it and if my steps are right?
1. If your update.zip is not official(signed) then you can't update your device.
Download this and rename this file to update.zip and retry.
Its a signed update.zip

If not work then just find your radio update in this list..

Thank you very much, I will try it tonight.
Damn, now I get a
"failed to verify whole-file signature" error???
What´s wrong now?
Maybe I need a Certificate to put on my sdcard for the whole file?

[Q] Installing CWM Recovery (and CyanogenMod) via Odin/ROM Manager not working?

I'm quite new to all of this flashing stuff-- sorry if I sound like a complete newbie.
So I'm trying to get CyanogenMod on my Samsung Mesmerize (Galaxy S), though to no avail. I tried to follow the guide on the wiki located at http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_S:_Full_Update_Guide though it's not working. I can't even get CWM Recovery on it.
To get CWM Recovery, I'm following http://forum.xda-developers.com/showthread.php?t=734166 -- it says flash back to a stock kernel first, which I did via Odin and by following http://forum.xda-developers.com/showthread.php?t=881064 (I downloaded the "EC10 Full Froyo Restore Package"... not sure what the difference is between that one and EE19 but it seems to work.)
I'll go over my steps from the beginning, starting from when I'm flashing back the stock kernel on my phone:
Flash back stock kernel (EC10 Full Froyo Restore Package) using Odin (I've also tried flashing the EE19 one)
It starts up after this, however it briefly displays "FOTA wipe failed" in red and "wipe_data failed" in yellow (along with some other stuff too, but no other errors - when I use EE19 these errors occur as well)
It starts up into the default Android system recovery - I choose reboot system now
Root my phone using SuperOneClick ('yes' to install Busybox prompt)
Insert SD card, Download & install ROM Manager from the Market (following this guide which I linked up above)
Select "Flash ClockworkMod Recovery" (Current/Latest Recovery: ClockworkMod 2.5.1.2)
Select "Galaxy S i9000"
Superuser prompt appears, I click accept
ROM Manager freezes for a bit, then displays "Successfully downloaded ClockworkMod recovery!"
Choose "Backup Current ROM" - freezes for a bit, then phone begins to restart... enters default Android Recovery mode:
Install from package... Finding/opening/verifying update package...
E:Failed to verify whole-file signature
E:signature verification failed
Installation aborted.
When I reboot and enter the recovery mode by holding volume-power-home,
it displays "E:Can't mount /dev/block/mmcblk0p2 (No such file or directory)" at the bottom.
Also, when I try to "wipe data/factory reset" in the stock Android recovery mode, it gives this error:
E:Can't mount /dev/block/mmcblk0p3 (No such file or directory)
E:install_application_for_customer:Can't mount HIDDENSDCARD:
your storage not prepared yet. please use UI menu for format and reboot actions.
I also know there's a "Manual Flash Overrride" option in ROM Manager - could I flash CWM Recovery manually and go that route somehow?
My final goal is to get CyanogenMod installed on my Mesmerize, though-- however, I need CWM Recovery to do that. Any ideas as to why CWM Recovery isn't getting installed, and how to fix the mmcblk0p2 error message in recovery mode (and if that's affecting anything)?
Thanks!
MOD EDIT:
FORUM RULES:
Encouraging members to participate in forum activities on other phone related sites is prohibited.
Yes, and i will add ROM manager only works for Mesmerize MTD systems, and CM7 IS MTD. SO, technically you need to be on CM7 already to use ROM manager.
You don't need to use ROM Manager period.

[Completed] Can't install CM12 to Galazy S2 I9100P

I've downloaded the latest stable files and followed the instructions here to the letter:
http://forum.xda-developers.com/galaxy-s2/development-derivatives/rom-cyanogenmod-12-t2955551
But I cannot get CM12 to install. If I boot the phone using stock recovery I can see and select the CM12 zip file but I get the 'Signature verification failed' error. If I use CWM recovery where I can toggle signature verification on and off, it's like it can't even see my SD card. Even though it says that the current directory = /sdcard it isn't, and instead just shows everything on the device internal memory.
Can anybody help? I've been stuck with this for about 8 hours.
I've also tried installing TWRP recovery. This does at least see my SD card and let me choose the CM12 zip file, but when I press the 'FLASH NOW' button, it asks me if I'm sure I want to reboot to recovery and complete the specified actions then does absolutely nothing when I select 'OK'.
Having spent hours trying various different things, I've made some progress and can now at least get CWM to see my SD card and the CM12 zip file. Unfortunately the installation fails with an error 7. I've deleted all of the 'getprop' entries from the 'updater-script' but it's made no difference. Please can someone help?
Thanks to the overwhelming support and advice received on here I managed to get it working
I'm posting this in case anybody else happens to have the same problem and finds this thread. This is what worked for me:
1. Download and install Odin
2. Flash stock ROM
3. Flash rooted kernel (I used one with CWM pre-installed)
4. Update CWM to v 6
5. Perform factory reset
6. Wipe cache
7. Wipe Dalvik cache
8. Install CM12
9. Install Google apps

Damn guys, please help me [huawei crr-l09]

So, lets start.
I have the mentioned Huawei Mate S, i flashed the TWRP bootloader and just wanted to root my device..
that have i done untill now:
- found a page (cant post the link cause i am new here) to root [search: "huawei-mate-s-root-twrp-recovery-v2-8-7-0/" in google and take the first page to get there (theandroidsoul .com) ]
- downloaded everything mentioned (TWRPand i got the SuperSU-File)
- first i loaded into bootloader, then made a backup of my system.
- then i installed the System again with the SuperSU.zip File
- i tried to boot the system, but it was stuck for 8 hours in the Huawei System Boot Page while i slept
- then i rebooted into the recoverymode of TWRP and restored the system again from the backup, but this time without installing the SuperSU. I could reboot but my phone wasnt rooted, so i tried again:
- this time i just installed the zip-file using the twrp-recoverymode
- didnt work
- and then i think i made a mistake, i tried to do a factory reset but after like 15 minutes i thought it would be stuck and i rebooted
- after the reboot no matter what i did there was always that problem: "E: unable to mount "/cache" "
- i tried a a couple different things and now i am at this point:
-> my android system isnt booting so its stuck in the bootpage
-> i dont have the backup (dont know where it went) anymore so i cant restore with that
-> i cant wipe the /cache cause everytime it says: "E: unable to mount "/cache" "
WHAT CAN I DO? maybe flash a custom rom?
PLEASE HELP, THANK YOU! <3
ccas
edit: phone is listed in pc so i can transfer any files, but its empty, there is only one file called "TWRP"
Flashing a custom ROM may fix it.
If not, I'd try to flash the original firmware. Huawei must have some software available that allows you to do it.

Not able to flash Stock image with custom Recovery (TWRP 3.1.1.1.)

Hello guys,
Today I wanted to update my Honor 8 (FDR-L09) because it was showing me, that there is a new update ready to install (FRD-L09C432B405) and I was on a very old firmware (something from mid 2017). So it was time for me to update.
I downloaded the latest update (FRD-L09C432B405) and tried to wipe the cache, dalvik, and Data, but for some reason it "couldn't mount /data" and the wipe failed.
After an advanced wipe it worked and I tried to flash the stock image (the update which was shown to me (FRD-L09C432B405) with TWRP (3.1.1.1.)).
Now my hassle starts:
1. The Rom couldn't get flashed because of "Error: 7" --> I fixed it with the common "Error 7 fix --> editing the update-script and removing the assert line. (And yes, I'm 100% sure that it was the right ROM.
2. Now TWRP seemingly starts to flash the rom but inbetween the lines there is "mountencrypt: failed to mount /data: no such file or directory and it ends with "unknown command [[]" and it takes just two seconds, so the flash obviously isn't succsessfull.
I tried the "failed to mount /data" fix, where I change the data system to ext3 and then back to f2fs and change it back, but it won't work.
In my frustration I did another pretty bad thing and made another advanced wipe and wiped the system too, so now I don't have an OS on my system.
Maybe it's also important to note that there was a window showing up for a very short amount of time, with something like "encryption/encrypted" showed up.
What should I do now? Is there a way to fix the "/data couldn't be mounted" problem? Or am I missing a vital step in flashing the stock rom?
Thanks for your kind help!
You can not flash an update with twrp unless you use hurupdater. You essentially bricked your phone. Look for hurupdater here on xda and follow the instructions and you'll be fine
