[Q] My CWM 3.x.x.x backup doesn't work : SGS2

Hi,
I checked through many threads to see if anyone had a similar problem but couldn't find anything unfortunately.
Background :
I was running a Lite'ning ROM on my Samsung Galaxy S2. You're probably familiar with this ROM, but for those who aren't it gets flashed with ODIN and comes rooted and pre-installed with CWM.
I forget which version of Lite'ning ROM it was, but I am fairly certain it was pre-1.5 as the bundled CWM was definitely version 3.x.x.x (later versions I found had 4.x.x.x and 5.x.x.x).
I wanted to try a version of GalnetMIUI for something a bit different and hadn't changed ROMs in quite some time, so I booted into CWM 3.x.x.x (maybe 3.0.0.2?) and did a backup to the internal SD. This came in at around 1.4 GB and comprised of 4 files :
cache.img
data.img
nandroid.md5
system.img
I copied these to my PC too, just in case they somehow got erased from my phone.
Once I'd done this, I then copied the new ROM .zip file (latest version of GalnetMIUI) to the root of the internal SD, booted the phone into CWM, wiped user data and Dalvik cache, then proceeded to install it.
The problem :
I can't get my apps or data back. I was under the false impression that my Google account was automatically backing this up for me, and would restore everything once logged in as it had in the past (factory resets etc.). So once this didn't happen, I tried using CWM to revert back to how things were before installing the new ROM but although the restore appears to work I end up with issues.
I've tried a number of different ROMs and they either get stuck in 'boot loops' or a black screen after running through the restore procedure. I've tried restoring just data via the 'Advanced' option but this doesn't help.
I was under the impression that I'd be able to fully restore the ROM backup if I needed to, and have the phone running exactly how it was prior to messing around. It would seem this is not the case.
In desperation I tried flashing every Lite'ning ROM from version 1.0 to 4.2, restoring my backup each time but as mentioned I always get boot issues.
Have I lost my data? I hope not, as I had 'To Do' lists and all sorts of things that would cause problems if they were not retrievable. I realise this is a lack of knowledge and foresight on my part. I'm thinking now that I should have run Titanium Backup prior to this, and not assumed that CWM was going to provide a complete solution.
Hope all this makes sense and if any of you have the time to read through and offer advice it would be greatly appreciated. I am currently running a very pretty and slick GalnetMIUI without any of my data!
Thanks in advance.

Thanks for that, I'll give it a go tonight after work. Am I right in thinking that if it doesn't work I can extract the individual files and insert them manually to get my app data back?

OK, so after hours of searching I'm still no wiser as to how to install CWM 2.5.1.2
I found a zip file that was apparently version 2.5.1.2 but when I tried to install it from inside CWM 5.0.2.6 (included with GalnetMIUI) it sometimes gives an error, sometimes it reboots CWM and sometimes it simply says it has successfully installed (it lies). No matter what it says or does, it doesn't seem to actually replace version 5.0.2.6 with the older one and every time I do the three-finger boot it loads up the latest version like nothing changed.
I'm just so lost. All I want to do is restore my old backup, get my data back and move on. Please someone help me before I go insane from all this research!
[EDIT] In case any more information is needed, my exact procedure for installing version 2.5.1.2 of CWM went like this :
Download 2.5.1.2 zip file
Copy zip file to root folder on internal SD
Boot into CWM 5.0.2.6
Select "install zip from sdcard"
Select "choose zip from sdcard"
Navigate to 2.5.1.2 zip file, select and confirm

Can anyone help me at all?
In particular I'd like to know how I can downgrade to CWM 2.5.1.2 or similar in order to give [email protected]'s suggestion a go.
Failing that, if anyone has any suggestions whatsoever about how I can get my backup data restored it would be greatly appreciated. After spending some time with MIUI - in particular the Galnet ICS build - I have nothing but praise, but I really have to get my data back!

You should be able to downgrade through ROM manager. Go to "All Clockwork Mod Recoveries" and just flash one that is not 5.x.x. Any backup not made with version 5 will not work with the new version So if you can flash one that is version 2, 3 or 4 you should be good to go. If that doesn't work you can fastboot flash it. There are guides on how to do that.

Wait.....did you mount /system before installing the CWM zip ?

Sorry for the delayed reply, for some reason I didn't get an email notification that my thread had been updated.

For some reason, when I select "All ClockworkMod Recoveries" the only two options are 4.0.1.4 and v4.0.1.4. I'll have to look into "fastboot" flashing as I've never heard of that.
By the way, if I boot into CWM via ROM Manager the version that loads is 4.0.1.5, but if I perform the three-button combo when switching my device on I get version 5.0.2.6.

I didn't, is that something I should try?
Edit - Just tried this and at first it rebooted CWM and the version number hadn't changed. Doing this again yielded me the following error with no change in version number :
Code:
E:Error in /sdcard/CM V 2.5.1.2_update.zip
(Status 0)
Installation aborted.

I found out that I can extract the contents of my backed up .img files using unyaffs.exe.
Unless I'm doing something wrong, it would appear that my backup is corrupt somehow. When trying to extract data.img, it processes for a while and does bring back a lot of files but I also get the following :
Code:
read image file
: Bad file descriptor
read image file
: Bad file descriptor
data.img is around 1.2GB but the files I extract only amount to around 190MB.
It would appear that I don't have my contacts database in there which is annoying as for some reason there were quite a few that didn't get synced to Google's servers.

[Q] Startup error - installed wrong script

To whom ever can help out, I have a Galaxy Tab 2 7.0, and cannot seem to get my problem resolved by myself. I have somehow inadvertently managed to install an update.zip that had or had no relations to this particular OS of this particular model of android.
My problem is that I wanted to be able to, migrate my apps to the external SdCard or extSdCard, and I think I used an update.zip designed for the cellphone HTC Evo 4g. Not realizing that I will be later unable to use the restore feature from a previous backup I had made using CWM 6.0.1.0 to recover from my inadvertent mistake (not to comfortable making a backup, and thinking I can restore properly anymore, like I can on my cellphone that I am spoiled with).
Silly of me to think I could use an update.zip designed for another type of device such as the HTC Evo 4g, but… (anyway my bad what was I thinking…?). The update.zip, by the way is "dtapps2sd-2.7.5.2-signed", like I mentioned this is clearly designed for the HTC Evo 4g, and not for the Samsung GT2 7.0.
The problem I experience now is not complete lose of my GT2 7.0 device I can still install and change out OS through the CWM-Recovery and install apps through the Android Market. I do however experience the inability to check my Storage properties under my Settings profile. When I attempt to click on this link it pauses for a second as if it wants to open up and perform its normal function, then reports an error "Unfortunately, Settings has stopped". Now at this point this is where I would have to mention another issue similar to this one, and that is at startup. When I first start the device up and it runs through its process of startup configuration. It will then report a list of programs that are prevented from running properly it as follows;
Unfortunately, the process android.process.media has stopped.
Unfortunately, My Files has stopped.
Unfortunately, Factory Test has stopped.
Unfortunately, MTP has stopped.
Now my question is, how is-it possible to resolve this issue. I have tried to complete a fresh install of the OS, CWM-Recovery, and also attempted to wipe everything possible that the recovery will allow, but I am not expecting much, as I cannot even get the backup and restore feature to work efficiently enough to provide me with what I need it to do…
I have provided this post with a download of the update.zip I used as well as the version of the OS I have provided my Samsung GT2 7.0. If anyone can shine some insight on what direction I should attempt to do to resolve this issue I would be more that interested to take a look at what I could use to correct this error of mine…
-Samsung GT2 7.0 - OS (Use the Download link above the Rosewell signature)
http://forum.xda-developers.com/showthread.php?t=1784318
-dtapps2sd-2.7.5.2-signed
http://www.mediafire.com/?7jpc5oudzt6o76p
I might be comfortable to ADB Shell into my device to make changes, or if one was able provide me an update.zip/script that would be great. Also is there a better recovery out there than the ClockWorkRecovery.

Better recovery so you may try twrp or so
Try install a fresh firmware preferably with a pit file from odin pc

Factory reset in stock recovery. So Odin a stock Rom and before u install anything custom, do a factory reset in recovery after u Odin back to stock. Then flash away.
I imagine you have alrdy tried a factory reset using a custom recovery.

WAIT!!! You don't have to factory reset, just reboot into CWM recovery ang go to mounts and storage>wipe internal storage. Confirm and reboot. You will lose anything on the sdcard but your apps will stay.

1. I am all over the Factory resets, and wipes.
2. Already tried Stock Rom(s).
3. I believe my problem is a bootloader, or partitioning script. (As this denies me access from inside settings>storage where I can view my allocated size, and Restore to Factory button. In addition in CWM, I am not allowed to mount/sdcard(internal), extSdCard is ok though. Also, I cannot plug Tab via USB to check contains on Internal or External sdcard, but I can remove the External to transfer data from it via sdcard slot on PC...)
Maybe you can recommend a good Stock Rom, so I can give that ago...
I was in the process last night, and could not get a good connection with Heimdall or Odin. I am now looking into driver issues, so...

Ok, so I was successful in taking RomsWell and MultipleMonomials advice, and was able to return my device back to "Normal" state, including "Stock Recovery". But I still have the original problem as in my request I asked in my first post...

I think now, if I cannot get a sizable remedy..., is just to try and send it in Samsung so they can take a look at it...
Any suggestions...?
FYI; I have also tried connecting to Kies, but due to the inability to posses a "MTP" (Media Transfer Protocol), is the reason I cannot connect to my SdCard & extSdCard. I can "PTP" (Picture Transfer Protocol) into it, using "adb shell", but not using "MTP"...
So I do not know how much "MTP" has to do with this relationship of the other three items that I mentioned in my bullet list in my quote, but...
Anyway, I don't know what I am trying to say, but thank you two, for getting me this far...!

Did you try formatting internal storage in CWM?

I am not quite confident on how much this will work. As I have tried this multiple times to wipe "Wipe Factory/Data", "Wipe Cache", including all the partitions under the "Advance" section found in CWM Recovery. Even using TWRP Recovery.
Per this post; I just attempted to flash a "Stock Rom", but not before doing a factory/data, cache wipe using "Stock Recovery", including after a successful install...
No luck, the same problem still exist as above...

Ok, this was all just the rudest experience I put my self threw. As I have an HTC Evo 4g - cellphone and have become comfortable with installing ROM's, Kernels, and Updates.zips, as well as, other modification. All threw the Recovery designed for this particular device, and don't get me wrong there has been a couple of times. Maybe more than a couple, more like a few times I have installed incompatible downloads I find in the XDA forums. Which makes this screw up, difficult form me to know that as long as you can get into a Download/Bootloader or a modified Recovery designed for a particular device that was successful flashed correctly. Well the screw up are easily redeemed/recoverable.
So, to make a long story short. After having called Samsung Customer Care (the 1-800-SAMSUNG) number, it seems to have been a External SdCard getting in my way from having been real short from sending my Tab off to the repair department (where ever it is...). I in fact already had it in an envelope, all I needed was an address to send it to. Anyway the nice person on the other side of the phone requested that I remove my External SdCard, and confirm that I was able to get into my "Storage" tab under my settings. Well after success getting this option back, I then made the suggestion that maybe my Eternal SdCard is corrupt or incorrectly formatted. She then agreed maybe this is the case. After ending the phone call. I quickly restarted my Tab, again only to find out that I was no longer receiving the error messages like mentioned above, which is great, because after multiple flashes of "Stock Roms w/Stock Recovery", and forcing myself to believe that it was a system install error. It in fact the External SdCard in place preventing me from throwing my Tab against the wall / in the mail to Samsung Repair Center...
"Man what an ordeal...!!!"
Thanks to all that helped with the suggestions, as to what direction I most defiantly tried.
I am now in the process, since I am living back in Stock mode. To receive an OTA (Over The Air) Update, and am still in the process of seeing if this thing still possess any residual silent errors...
I will keep you posted.
If not, well it off to happy rooting for me...!!!

That is it, my problem is resolved. Damnedest thing this problem of mine, it seems the only thing I screwed up was the micro SdCard. to the point it was the cause of all the error I received when I started up the device, as well as when I attempted to access my storage through me settings options...!!!
Now re-rooted, and a happy camper, Cheers...!

[GUIDE] How to restore your Nextbook Ares 8 - NXA8QC116 to Stock (TWRP/Rooted)

After tinkering with the tablet and trying my best to restore it I finally was able last night to restore it to a clean install using this method. I'm sure there may be other ways to do it as well but this worked for me and was painless.
1. Make sure the tablet is rooted/unencrypted using Vampirefo's guide:
http://forum.xda-developers.com/android/development/root-nextbook-ares-8-twrp-recovery-t3133165
2. Make a backup of your System, Boot, etc. of your current boot-looped ROM with TWRP.
3. With TWRP's file manager, go into the internal storage and delete all the files within the backup folder.
4. Download this backup:
https://onedrive.live.com/?id=19085CD12562E567%21931&cid=19085CD12562E567&group=0&parId=19085CD12562E567%21925&authkey=%21AHmuVovnpuzX0tI&action=locate
5. Extract the files from the zip and copy them over to the backup folder on the internal storage.
6. Go to Restore on TWRP and dance.
After many attempts of trying to restore from an external SD card and from just creating my own TWRP backup folder, TWRP just wouldn't see the backup until I copied and replaced. I'm glad it worked and I hope it helps anyone else who needs a restore.
Credit goes to jmreyesiii for providing the backup files and vampirefo for the rooting.

An absolutely great post! You need a special thanks because this ability to recover from catastrophe likely will encourage others to move forward with more daring mods. I feel much more secure in playing with a few ideas knowing you have the base Rom and recovery spelled out and that it actually worked (Yes, I knew how, but knowing it worked for sure is huge!)
Thanks,

Now if only some kind hearted dev would release a ROM....

Actually, after you root and decrypt it, and fix the cpu governor and such, and get rid of the google apps that you don't use, with the exception of the lollipop HW overlay flaw it is not a bad ROM to start with. I wiped most of the Google stuff and put in Nova launcher. Now the device is quite manageable and very fast without much further help. Here is a pretty good summary of the device for anyone who has the tools to build a ROM: http://specdevice.com/showspec.php?id=ee2d-39de-0033-c5870033c587 with the exception I can not find that the FM radio exists in the device although the hardware seems to say it is there..........

[STOCK][TWRP BACKUP][UPDATE] AT&T H910_10L Stock Recovery, Boot, and System Image

Below are links to full backups that can be restored in TWRP for the H910 after the Dirty Santa exploit. This is useful for restoring a bad install once you have access to TWRP. I will outline three methods for install below that will help in putting back the TWRP backups, a good method for installing it, and a few suggestions I have from restoring my device about 10 times now. So without further ado.
UPDATE: I bricked my device and had to send it off for repair (turns out I can't just flash US996 firmware for funsies) I received my phone back with the still rootable OTA 10L and yesterday I rooted it again and uploaded the new firmware. So if you're an AT&T user who wants the second latest update (10M dropped 04-15 but it isn't rootable as far as I know) then you can grab this and run it along with the stock kernel I made a backup of. I'll update the links below to reflect this. Stock 10L kernel located in tips section. Not flashable, you must extract and install as image and immediately install SuperSU 2.79 or greater or your device won't boot!
How to Install and Restore Stock Images and Boot (Kernel) Image
1.) DOWNLOAD - https://www.androidfilehost.com/?fid=673368273298948069 (Updated to 10L) download the file and verify the MD5sum of the zip matches the file you downloaded. (System image link for devs posted at the bottom)
1a) Download the latest SuperSU 2.79 flashable zip from here: http://www.supersu.com/download
2.) EXTRACT --This is not a flashable zip-- extract the zip file wherever you would like so that it can be copied to the device
3.) COPY - The extracted folder to TWRP > BACKUPS > (paste here) on either the MicroSD card (preferable) or internal storage (This will be wiped when you format data)
4.) REBOOT TO RECOVERY - Once the folders are copied to the backup directory you can reboot to TWRP to begin the restore process.
5.) WIPE - This is getting two sections in order to account for two situations
5a) MICROSD - If you have a MicroSD card and copied the restore files to it wipe everything: Data, Cache, Dalvik/ART, Internal Storage, and System.
5b) INTERNAL STORAGE - If you don't have a MicroSD card installed only wipe the following: Data, Cache, Dalvik/ART, and System.
6.) REBOOT TO RECOVERY - Once you have wiped everything, especially if you wiped internal storage, you should reboot TWRP before you start the restore process
7.) RESTORE - Back in TWRP Choose Restore from the main menu and if you can't see your restore file choose "Select Storage" at the bottom and inside that folder uncheck RECOVERY unless you want to overwrite TWRP (which I recommend against).
7a) I would recommend checking the box "Enable MD5 Verification of Backup Files" which is a little slower but ensures a good restoration
8.) SWIPE - Swipe to begin the operation and it will alert you upon completion. You will need a very large amount of space on your card to do it since the system image is split into 3 packages
9.) ROOT - Do not reboot until you have rooted! The unlocked bootloader will prevent booting on the stock kernel. The stock kernel can be used if it is rooted first, otherwise you will be stuck on the LG Boot logo.
10.) REBOOT TO SYSTEM - The phone will reboot itself! Don't panic, this is part of the standard rooting procedure. Now, see tips at the bottom for best performance.
TIPS!
- This is the 10L update stock kernel made during dirty santa method. This kernel has all features working minus the static on boot being gone, but Wifi calling, comfort view, FM radio, etc are fixed using this kernel. https://www.androidfilehost.com/?fid=817550096634762281 (You must flash SuperSU 2.79 or greater after flashing this kernel before you reboot! Not Flashable, must extract)
- To use the above kernel, download his ROM and extract the boot.img file from that archive. Save it to your device, boot to TWRP, choose Install, Install Image, and click the boot.img file. Then choose the checkbox for "boot" and swipe to flash. Really important to install SuperSU again after installing the custom kernel.
- Boot-up static can be cleared by allowing phone to boot to screen off, placing it face down to turn of second screen, and then flipping it back over. Static will be gone until next boot.
- Using fstrim after wiping in TWRP is good for increasing flash drive performance. Go to TWRP > Advanced > Terminal and type fstrim -v /data/
- You can do fstrim on /system and /cache as well to get all three partitions running clean
- Some of the AT&T apps that you can remove with TiBu are tied to bootup. Be careful what you remove if you like to get past the AT&T logo.
- The button combo to get into TWRP from powered off is Vol Down + Power until the LG Logo appears then let go of power and immediately press power again.
- That button combo boots you to a screen asking it you want to wipe your device. Answering 'yes' to both questions boots you to TWRP.

9.) ROOT - Do not reboot until you have rooted! The unlocked bootloader will prevent booting on the stock kernel. The stock kernel can be used if it is rooted first, otherwise you will be stuck on the LG Boot logo. [/QUOTE] What exact method of rooting do you mean, without rebooting? Do you mean just flashing SuperSU? Can you clarify? THANKS for everything! Hoping this gets me out of my semi-brick. No matter what I flash...it keeps reverting back to TWRP.
EDIT: I did this, exactly...and yet again...I'm stuck in the phone autobooting back to TWRP. Any suggestions? Is this bricked?

If you do a battery pull and can get to TWRP you are not bricked. However, I have no idea what you did to get a bootloop. What kernel did you install: the stock one from TWRP or Tilde88's kernel from his ROM? Either way, if you did this:
Wipe > Restore (Boot and System) > Install SuperSU 2.79 zip > Reboot
then you did the correct steps. The issue of not having SuperSU installed on my device was not booting past the LG logo and never rebooting. However, the method I most recently followed was:
Wipe > Restore (boot and system) > Install Tilde88 kernel > Flash SuperSU > Reboot
and my phone has been running extremely well. I need way more info from you before I can help you further.

Shoot...I think I followed your instructions in Tilde88's thread....and hit reboot instead of flashing his kernel. I then went back in to TWRP to reflash the entire thing...and the kernel...and I was given crap about encryption. Then, that's when the bootloop started. Right now, I'm sitting on TWRP. I've tried flashing everything, per instructions....but I guess, what I'm asking, is...since I'm on TWRP...and it's bootlooping because of encryption...what would you personally do? Shoot...I'll pay ya if you can fix this! LOL. I just really never dealt with the encryption thing until this phone...never really had problems till now.
---------- Post added at 09:28 AM ---------- Previous post was at 09:12 AM ----------
FLASHED EXACTLY THE WAY YOU DID (WITHOUT THE REBOOTING TO RECOVERY IN THE OP)...NOW, IT GETS TO STATIC, THEN LG SCREEN, REBOOTS ONCE TO STATIC THEN BOOTS UP!!! YAY!!! :good::highfive:
I guess there's no need to REBOOT TO RECOVERY if a person faces encryption issues and is trying to fix their phone. Even after decrypting, I came up with issues. Now let's see if this this asks for my PIN on reboot. THAT was another issue!
IT WORKED!!! THANKS! I'LL now try to go back into TWRP and flash the Tilde's boot.img

So...by flashing your STOCK TWRP backup...per your instructions, I was TOTALLY FIXED...I then didn't even flash Tilde88's kernel...I immediately rebooted back to TWRP, and DID NOT WIPE...but immediately flashed his ROM....and BOOM! Google Now/Always On works flawlessly, zero lag! AWESOME!
So, to all that are having issues with no Google Now/Always On...follow this instructional on this thread and DO NOT wipe after flashing Tilde's rom.
BTW, I shot you a PM, bro! :highfive::good:

Nothing like some good news to start the day. I wanted to let you know that the reason this worked is that it is essentially a dirty flash that replaces the stock kernel and adds his ROM tweaks into my stock system. So once it had booted and you flashed over it you were able to keep the stock files needed to get screen off Google Now working while adding his audio tweaks and build.prop because they overwrite the stock files. Since my stock files are odexed and his are not I'm not sure how well all your system files will function since they've been overwritten but if you have no issues then no harm, no foul.
I'm glad this got sorted and to anyone else if you follow this guide and you have any confusion about the instructions just do an @AlkaliV2 and I will do my best to help and I will also fix up the guide so that it is less confusing. Just let me know.

Stuck again....in TWRP.
Delete please

Same issue
i followed it to the letter yet i still keep being returned to team win recovery no matter what i do.

Great step by step instructions. Thanks!

Try booting into your bootloader (fastboot) and type:
fastboot erase misc
fastboot erase cache
fastboot erase fota
fastboot reboot
See if that helps you at all. Make sure you have a valid ROM flashed correctly though.

im having trouble, i downloaded the file, and i put the extracted folder into TWRP>BACKUPS but when i go to restore on TWRP theres no files to be open, am i supposed to keep the file as a zip or?

I was having the same issue, do a backup(choose something small) from TWRP. It will create the TWRP>Backups Folder for you and then you can place the extracted zip. from this thread into that folder and it will see it.

i've tried what you suggested, and still nothing seems to show up, i made a back up in both internal and micro sd

So you created a backup of let's say the EFS partition in TWRP. You backed it up once to the internal SD card and once to the external sd card. Then you extracted the zip from step one, placed the folder inside of the backups folder and it does not appear?

how can i use this file if i i'm not rooted? My phone is being weird and i would like to reload the stock software on it.

You cant all you can do is factory reset on stock

Does the factory reset to stock also reset the recovery? Want to root phone but will most likely trade in to ATT once I'm eligible for upgrade(with trade in).

right now the root method for the h910 does not allow you to go back to stock

My 8gb sdcard ran out of space during step #8. Can I copy the contents of the sdcard to a bigger card and redo the full restoration from step 1?

Having the same issue. I copied the folder over to the microsd card and the folder I copied over isnt showing up in restore. I cant do anything or wipe anything if I cant see a backup right?
Im going to try and do the internal storage copy. No other choice.

If you create a backup of anything on the Microsd card before you attempt to put the folder in it, it will create the directories for you and all you have to do is copy and paste at that point.

G930F won’t install files

Hi! I have been searching on the web for the Stock ROM to G930F, but the phone only installs the modem.bin file. Everything else throws a error on the phone, and in Odin. So i’ll tell you how this happened, And yes this might be a long story.
I wanted to use Samsung Health to check my puls.
I opened the app and it said that I couldn’t use this app because the phone was rooted. (I had rooted my phone in the past and downloaded a stock ROM to flash my phone with to start off clean)
And so I thought I’ll just fix it now, because I am on computer. So I flashed my device with TWRP and mounted the system and the data. I saved the build.prop file on my computer and changed the Knox Trigger Value to 0. When I flashed the file back after editing it, ADB said it couldn’t read the file. I thought “what the hell?”. I rebooted the device, plugged it off my computer and noticed something was odd. It began to bootloop, the start-up image when you power on the device. I got into Recovery and checked to see what was wrong. It said the Internal Storage was (0 MB) used. I was powering off the device, and it said “No OS installed!”. I tried flashing the stock ROM but it would only accept the modem.bin file. I was worried and didn’t know what I would do. Any help would be great!

Ok so you don't say what firmware you had and which one you want to flash., there are lots of firmware for the G930. You can download them from several places , sammobile, SamFirm Tool and updato.com.
Use the latest version of Odin if you want Oreo, preferably unbranded.
With regard to Samsung health, this app will not work on a rooted device, just like banking apps, network provider apps and any other app which hold personal info.

As @cooltt said use SamFirm tool (search it on google, it's here on xda) and download the latest firmware for your variant (ex. SM-G930F if you own the international S7 flat).
Flash with odin. Make sure you put all the files in the right tabs.
Let the phone boot completly (until the tutorial shows up, if you used the CSC file instead of the HOME_CSC one)
To be able to use SHealth you will need to edit the build.prop. To do so:
1) flash twrp
2) boot to twrp and wipe data (you will loose everything you have in the internal storage so make a backup)
3) Reboot to recovery (twrp menu > reboot > recovery)
4) Flash Magisk 18.1
5) Reboot to system and wait until the phone boots (it may take 5-10minutes)
6) Set up everything and go to play store. Download BuildProp Editor
7) Open BuildProp Editor and make sure you grant it superuser access in Magisk
8) Search for the property: ro.config.tima and set its value to: 0
9) reboot the phone and you should be good to go.
If you want OTAs you will need to 1) uninstall magisk and 2) wait until the next update is released and flash it with odin using the HOME_CSC file.That will revert the kernel to its original state (non-rooted), the recovery to the stock one and the system and binary status to Official (which will allow you to receive OTAs once again)
