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!

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.
Hi, i received HTC sense 3.0 and android 2.3.5 update. I tried to update it but it stuck on boot screen. Restarting didn't help. So I wiped all the data but later realised I no longer have clockworkmod installed.
I go to hboot and try to put recovery on sdcard through adb, but adb cant find my device.
Is there anything I can do? My phone is pretty messed up now, and I don't know what to do RUU also doesn't work, because my phone can't be found.
// #1 OK I managed to install clockworkmod through the Android Flasher. I've downloaded BeatMod BlissSense Hybrid v2.1.zip but I cant install it through the clockworkmod. It says:
"E:Error in /sdcard/BeatMod BlissSense Hybrid v2.1.zip
(Status 1)
Installation aborted."
// #2 sorry to bother.. I disabled the verification check in clockworkmod, installed su-2.3.6.3-efgh-signed.zip and then custom ROM.. everything now works fine. Of course with the help of tutorials on xda and great people over here.
This was the worst 4 hours in my live as I thought my phone is bricked.

You don't appear alone with problem, so thanks for re-editing the thread post to provide updates, if you have the time and could try to add any URLs and links to the files that you used to resolve your issues, then that would be great!
I've already several threads where it appears the update has put others in the same position, so your update could prove to be a useful resource assisting the recovery of others!
Cheers.

Install ClockworkMod:
What you need to do is get the phone to fastboot and connect it to the PC via USB.
Launch and update Android Flasher. Choose your phone and browse for recovery image (recovery.img that you have unzipped)
Click finish and wait. Clockworkmod should by installed.
Get files on the phone:
Go to recovery
Mounts and storage menu
Mount USB storage
Then copy files (custom ROM you want to install and su-2.3.6.3-efgh-signed.zip) from PC to SD card
Install Root:
Go to recovery
Install zip from SD card
Toogle signature verification (disable it)
Choose zip from card and install su-2.3.6.3-efgh-signed.zip
Choose zip from card and install custom ROM
Optional steps? (right after installing clockworkmod)
Go to recovery
Wipe data
Go to advanced
Mounts and Storage menu
Format /sdcard
That's it. Hope it helps.
i seem to have fubar'ed my nexus s (uk version) i updated to ics, didnt like it so tried to restore to a backup i made earlier today...
at the moment when i turn on my phone it shows
fastboot mode- No Boot or Recovery img
lock state - unlocked
I can enter recovery. but cannot restore.
tried wiping cache,dalvik etc.
When hitting restore it returns with:
... system.img not found. skipping restore of /system/
also does the same with
data.img
cache.img
sd-ext.img
i have no idea what to do... if you could help it would be greatly appreciated.
Try flashing a rom. U can mount SD card within recovery.
Sent from my Nexus S 4G using xda premium
yeah tried flashing ...
gets stuck on google screen
Do you have a One Click return to stock available for your model? It wouldn't hurt to start fresh. I did that on my NS4G last week. Does your PC recognize the phone?
Sent from my SPH-D710 using Tapatalk
looking into the unbrickable mod atm... my phone seems to have no .img files.
tried restoring to stock and still the same issue... it says it cant find .img so skips them then when i try to re boot it sticks on the google screen
After trying to apply from zip (cm7, that i have used numerous times before)
i get this ---
Installing update...
assert failed: getprop("ro.product.device") =="crespo" ll getprop("ro.build.Product") == "crespo" ll getprop("ro.product.board") == "crespo"
E:Error in /sdcard/update-cm-7.0.3-NS-signed.zip
(Status 7)
Installation aborted.
i havent the faintest idea what to do...
Tried re-flashing CWM recovery?
yup tried re flash,
i think i need to replace the .img files... i just dont know how
it says that
system.img not found
data.img not found
cache.img not found
sd-ext.img not found.
it skips the restore of these say restore complete. yet there is obviously nothing to restore.
there must be a way of fixing this???
Do you have the latest version of CWM flashed? (5.0.2.0)
yeah re installed/reflashed (5.0.2.0)
it seems to be working

Facepalm

Such a noob
I have had a similar problem before, and even advised on that exact thing.
lesson learned.
KEEP RECOVERY.IMG UP TO DATE
Thank you for pointing out the obvious.
I'm such a ****
No problem flex59, best way to learn is the long and hard way . I had a similar status 7 problem on my move up to ICS. Figured the latest recovery will save me wasted hours down the track eventually, and hopefully someone elses.
To downgrade from ICS, you need to flash the full GB 2.3.6 ROM first...
I downgraded from OTA ICS 4.0.3 due to battery, Wifi & lag issues as well. A NANDroid backup does NOT contain the bootloader and radio AFAIK. Here's what I did.
Find the appropriate FULL ROM here and download and copy to your SD card.
Download this flashable Superuser here and copy to your SD card.
Make sure you are familiar with and set up for fastboot and have the latest CWM recovery img file. You will have to reinstall CWM. These instructions are assuming that CWM recovery is already installed on your device.
1. Make sure the full ROM and SU zip are on the root your SD card.
2. I did a full wipe of data, cache, dalvik.
3. Go into CWM recovery and flash the full ROM. Now flash the SU zip.
4. At this point, the full ROM flashed GB2.3.6, stock recovery, bootloader and radio back. But you should be rooted due to step 3.
5. Boot into Android. I installed ES File Explorer from the market. In ES File Explorer settings, select both root settings “Root Explorer” and “Mount File System” to navigate and modify root files. Allow permissions in SuperUser.
6. Navigate to /system/etc and rename (tap&hold on file) install-recovery.sh to install-recovery.sh.bak (this file reinstalls the stock recovery at every boot)
7. Using fastboot on your computer, flash CWM recovery again.
8. NOW using CWM, restore your GB 2.3.6 NANDroid backup.
Like nothing ever changed.
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
Hello,
Glad you found your way,

I would like to install TWRP and after that Lineage OS on my Samsung S8+ (Exynos). So i tried flashing TWRP with Odin (Dream2lte version 3.3.1.0). But i ran into a FRP lock so i googled and try to solve this, but so far i am unable to.
I have the password to my Google account, so i removed the Google account from the phone and removed the phone from my Google account. After factory reset i am still getting an error FRP lock when flashing.
Shouldn't the FRP lock be gone after removing google account and doing a factory reset? I have tried a couple of YT Howto's but they don't seem to work.
How do i remove the FRP lock so that i am able to install TWRP and Lineage OS?
Like i said i know the password to my Google account and i 100% own the phone
(Bypass probably isn't the correct word, i am simply trying to turn it off )
Got exactly the same problem, hence like you, ended up here for help.
Well i fixed my problem (Disable USB debug and OEM unlock, couple of reboots and enabled them and it worked). But after that i broke my phone
I am stuck at the screen saying: An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.
I know this is meant to scare me (is kinda working...), but i also know that Odin is still working. So as far as i know i have to flash the original firmware now to fix this. But i keep getting the error: Invalid magic string. When i try to also flash a BL file i get the error: ""Secure CHECK FAIL: (BOOTLOADER)" The option Re-Partition in Odin is switched OFF, as far as i know this is okee... right?
I have tried 3 different versions (Android 9/8/7):
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXU1AQC9/128974/
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXU4DSBA/259612/
https://www.sammobile.com/samsung/galaxy-s8/firmware/SM-G950F/TNL/download/G950FXXS4CSA4/256485/
This zip files contain a BL/AP/CP/CSC file, i have tried them all at the same time in Odin as well as the AP and BL files seperate. (from one zip file, NOT different version files together of course)
I tried using Smart Switch 4.1 to do the emergency procedure using model nummer SM-G955F with my serial number but before it does anything it tells me this is not possible with an SM-G955F.
They all give me the same result.
Does anybody know how to fix this?

Secure check fail on bootloader is your flashing a older firmware than on the device. Look at the builds 5th from last digit. You need to flash that equal or greater than.
The error screen you see for emergency recovery is ok. It's like a modified version of download mode. Kind of. You can still flash Odin files from said screen. Ii see you've flashed a bit 1. And two bit 4 firmwares. So you must be on a 5 or greater. I don't know the exy bit number but like snapdragon is at or near 7 or 8. I can explain better if you need. But not an exynos expert

Thanks for your reply! I am in the normal "Downloading...." screen is there anywhere i can check which number i am at?
But i have just tried this one: G950FXXS7DTA6_G950FOXM7DTA6_PHN and it is not working. But this is the newest one available on sammobile. Still the same bootloader error.
I have tried TWRP 3.3.1.0 and that worked, now i am in the TWRP menu but i don't have the LineageOS 17 + GoApps copied to the root. So i cannot install LineageOS now. What do i do now? My computer sees a SM-G955F but it is not showing any storage, if i can fix this i could copy the LineageOS files to the root...right?

1. If you are on an S8+ flashing firmware for the S8 will cause you issues. Download firmware for the S8+ only. ie: 955f not 950f.
2. If you can't get into the system but can get into download mode there should be a line saying
AP SWREV: B:? K:? S:?
The B:? Is your bootloader version number. You will need to flash the same or higher.
3. How did you install TWRP?
If you don't have an SD card to store files on then after the Format Data stage you can then copy files from pc to phones internal storage.

I am a bit embarrassed, it looks like i have been trying to flash the wrong ROMs last night 950 instead of 955, i am downloading the correct files now and wil try again. Sorry for this dumb mistake!
Just to be sure, i am trying to do this:
https://www.getdroidtips.com/lineage-os-17-samsung-galaxy-s8/
(I do know that this site says S8, but i picked the right files this time and thought the process would be the same)
But i first Flash TWRP with Odin, otherwise i cannot reach the TWRP recovery menu right?
But when i look bullet 5 (not number 5) it looks like i need to flash TWRP from within the TWRP menu. But that is not correct right?
I have placed these zip files on the phone:
lineage-17.1-20200211-UNOFFICIAL-dreamlte.zip
open_gapps-arm64-10.0-pico-20200303.zip
As a zip and unpacked, but when i am in the TWRP menu and i go to install, i cannot find the zip files. I placed them in the highest folder level possible. Why can't i find them now?

I don't use custom roms yet.
Try searching for you device S8+ for installation instructions. Had a quick look the firmware is for S8 only not S8+. Need dream2lit for S8+
Try in separate stages instead of all at once.
I would sort out your stock firmware first get it up and running.
Then install TWRP. Install for S8+ from
http://twrp.me/Devices/Samsung/
They are many guides for this
https://forum.xda-developers.com/ga...pment/recovery-twrp-galaxy-s8-exynos-t3595102
If you need rmm bypass zip
https://forum.xda-developers.com/sa...w-to/guide-root-install-twrp-samsung-t3747535
Get that up and running properly.
Then you can install custom roms,root etc.
In regards to transferring files to phone they need to be a zip file ( .zip ) or an image ( .img ) files to flash in TWRP.
Maybe select internal storage then from menu select sdcard folder check if file is there.

I am using dream2lit.
I have the correct factory stock ROM (now), so i can always go back now. But i agree, my preparation wasn't good enough.
I will look at the links, but for now like i said my problem is that i cannot see my files in TWRP. But maybe that will be addressed in one of your links
With regards to your first link, i used the "Odin Method" so as far as i can tell i did this the right way(https://twrp.me/samsung/samsunggalaxys8plus.html):
Odin Install Method (No Root Required):
You will need to download and install Odin on your PC. Once you have Odin installed, download the proper .tar file for your device from the download link above. Power off your device. Turn on your device using the proper key combo to get into download mode and attach the device to your computer via a USB cable. Use the PDA tab or button to browse to and select the tar file that you downloaded and flash the device.
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.

Note: Samsung don't have fastboot commands. Have to use button configurations to enter recovery or download modes.
What stage are you at?
It will give me a better idea to be able to help more.

Well i installed Lineage OS 17.1 and Open Apps (lineage-17.1-20200211-UNOFFICIAL-dream2lte and open_gapps-arm64-10.0-pico-20200303) with an OTG plug and an USB stick. After installing i removed the USB Stick. But now i am having a new problem...
When the phone boots it asks: "To start Android, enter your password"
Which password is this? When i enter a password i often use it works but then:
"Decryption unsuccessful
The password you entered is correct, but unfortunately your data is corrupt. (Which is no problem)
To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google account.
(Button) Erase ALL DATA"
Of course i erase the data. Look at the attachment to see what happens then.
I will not give up, will get Lineage OS on this phone, and after that on my Tablet S2 and maybe even on my primairy phone (S10+)
What should i do now? Many thanks for all the help so far, and for help finishing this proces

Mounting data errors in twrp generally ( but not always ) means your device is encrypted/re-encrypted when booting into system. Twrp has issues with encrypted devices.
What version twrp are you using?
Have you flashed the no-verity-opt-encypt zip in twrp. This zip file will prevent device from re-encrypting when booting phone back into the system ( after the Format Data stage / reboot back into twrp)
https://build.nethunter.com/android-tools/no-verity-opt-encrypt/
What is your process of installing twrp?
If you have any passwords etc. installed delete them until after setting up you phone.

Mounting data errors in twrp generally ( but not always ) means your device is encrypted/re-encrypted when booting into system. Twrp has issues with encrypted devices.
What version twrp are you using?
Have you flashed the no-verity-opt-encypt zip in twrp. This zip file will prevent device from re-encrypting when booting phone back into the system ( after the Format Data stage / reboot back into twrp)

What is your process of installing twrp?

I am using version twrp-3.3.1-1-dream2lte and no i have not flashed that no-verity-opt-encypt zip. I assume i should flash this one the same way flash the Lineage ROM right?
No passwords used on the phone.
My process:
i put the phone in download mode (POWER+BIXBY+VOL DOWN)
I use ODIN to flash twrp-3.3.1-1-dream2lte, and when the phone reboot i press POWER+BIXBY+VOL UP to enter TWRP menu,
Then i go to WIPE and Advanced Wipe and i select the data, system and davlik cache. Then swipe to wipe it.
Then i go to INSTALL and flash lineage-17.1-20200211-UNOFFICIAL-dream2lte and open_gapps-arm64-10.0-pico-20200303

To install TWRP
1. Flash twrp with odin - reboot straight into twrp
2. In wipe menu select Format Data ( bottom right )
Type yes to format
3. Reboot back into twrp ( use twrp menu )
4. Flash no-verity-opt zip and if needed rmm bypass zip ( using install button in twrp ).
5. Reboot back into twrp then reboot to system using twrp menu.
6. From system reboot back into twrp.
To check if device is un-encrypted use backup menu - check data storage size ( If reading 0mb then device is still encrypted ).
Note: If all ok I would do a complete twrp backup at this stage ( keep backup on a separate storage device ).
Then you can install custom Rom's as per the installation guide of that Rom.

In twrp main menu
Select backup menu - select ( all ) partitions - select storage location ( bottom left of screen ) - then swipe to backup.
Note:
1. If backing up to internal storage copy/move backup to an external storage ie: PC, sd card.etc.
2. Since you want a custom rom backup of the EFS partition is important.
Rmm state can be found in download mode. It will have a line ( near the top ) saying RMM state. It will either say prenormal or normal /disappeared.
It won't hurt to flash it just in case.

I am really trying to do what you are saying...but when i try to "Format Data" (Step 2) it shows an error "Failed to mount '/preload' (Invalid argument). When i try to install no-verity-opt zip (step 4) at the end it shows the same error "Failed to mount '/preload' (Invalid argument). Which is probably because format data failed?
I am installing the zip from an USB stick with an USB-C to USB-A Converter. I don't think that could be the problem?
As Expected the "Data (excl. storage) is still showing 0MB.

Failed to mount preload seems to affect some users.
You could try after the format data and reboot back into twrp ( using twrp 3.3.1.1 ):
Select wipe menu
Select advanced wipe
Select Preload
Swipe to wipe
Reboot back into twrp
Then try flashing no-verity/rmm zips files - reboot back into twrp.
Normally, for me , after this stage If i still get 0mb I will reboot into the Android system and then back into twrp. Then check in backup menu storage. If ok then try to flash custom rom.

Yes Yes!! After doing the Preload i am able to flash no-verity/rmm zips file.
But Data is still showing 0MB.....
I thought why not give the lineage OS rom flashing another try. That worked, but now the phone seems to hang on a Lineage OS logo with a small circle moving around not straight line.
So i wiped everything again and flashed no-verity/rmm zip file, and will wait what for some advice and what do to next.

Have you tried to reboot into system through twrp ie: reboot menu - system. Let it start normally, reboot into twrp, then check storage size. ( This is after the flashing of the no-verity/rmm zip and rebooting back into twrp ).
As I said I' m not familiar with custom ROMs. I do know that some custom ROMs do take some time to boot up on installation.
But out of curiosity I have a spare S8 and will give it a go.
