What are the right steps? - Samsung Galaxy S7 Edge Questions and Answers

Quick question. I have a G935 on Android 7.0 rooted with twrp installed. Now I want to format it and go to 8.0 and then root it again. What are the right steps to avoid getting into bootloop or any other bad situations?

Download a custom rom from the forum for s7 and specify the country code for country specific changes.
Or just use odin and flash ap cp and bl for your version of phone.
None of the custom roms change your recovery just flash magisk in twrp for root.

So if I:
1) Download latest oreo from updato.com
2) Flash it over 7.0 as it is
3) Then without letting it boot in I go to twrp and do a "Format Data" from the wipe menu
4) Normal boot in menu
5) Reboot to twrp and flash supersu or magisk, will everything go ok?

You can format it before flashing anything.

You wipe data before flashing the Android OS.
You may wipe all data before flashing oreo but you don't have to wipe external SD or internal storage these two have no effect on Android.
The steps are long but this is a guide to truly get the stock firmware on your phone with nothing custom.
If you don't want to have slow download speeds basically you download the firmware package zip directly from samsung.
you may use samfirm application from the xda forums.
Just specify the 3 letter country code and phone model SM-G935F
Next boot your phone into download mode by restarting and holding power volume down and home button.
Then continue to odin download mode.
Download odin 3.13 because it is the only version that works with oreo.
Slot the ap cp bl and csc in the appropriate browse menus and click each of the check boxes to toggle flashing. Then click start to begin flashing the firmware.
The updato zip files have 5 files in them which are
BL the blue screen before odin mode.
CP it's the modem used for data and wifi
Ap it's huge its the Android os.
Csc it's the country code for your phone stuff like shutter sound in camera special apps. Will erase all data like the phone is factory reset.
Userdata csc keeps user data when flashing a csc not factory reset.
You only select Userdatacsc or csc for the csc not both.
If you want root then flash magisk or supersu in twrp after the Android os is installed.
Much easier if you use Civz or Galaxy project because all you have to do is install a zip file in twrp then select install options from a menu. They even have root available from these menus.

Just searched around... I found this "CivZ G935F-G930F Multi CSC". This is what you're talking about? So while being in Nougat I flash this from TWRP and follow aroma instructions as I please and that's it? I go to Oreo and rooted?

My advice would be to backup your contacts and sms with apps then restore them once your in oreo.
1. Backup sms and contacts using playstore apps.
2. Boot twrp Go to wipe menu advanced wipe and select all except internal storage and external media SD. Then wipe.
3. Go to install menu in twrp and install the CIVZ zip file select options from the installer you may choose your root version type during install.
4. Once your Android OS is stable and installed then you restore your contacts and sms using playstore apps.
Finally you also must update your modem and bootloader because they are oreo optimized (if u don't u will get battery drain) which are available for download latest is ERG2
https://www.androidfilehost.com/?w=files&flid=271397
https://www.androidfilehost.com/?w=files&flid=271403
Boot into download mode by restarting and holding power home and vol down then hit OK to go into odin download mode.
Plug ur phone into computer with USB.
Open Odin 3.13 on your computer and tick the boxes for bl and cp and browse to select both ur bl and cp for oreo hit start to flash and your phone should auto reboot with the oreo bootloader and modem.

[Q] N900 Rooted With Custom ROM to Lollipop?

i've been reading this thread over in the General discussions:
http://forum.xda-developers.com/galaxy-note-3/general/lollipop-ota-note-3-n900-started-t2973773
i currently have K14-Dr.Ketan custom ROM flashed to my phone:
http://forum.xda-developers.com/showthread.php?t=2519897
and my recovery is TWRP v2.7.1.0
the CSC code is: INU.
at first, i thought i couldn't update to the Lollipop update because its CSC code is XXV/THL
but then i saw a reply somewhere in the midst saying to flash a 4.4.2 version to change my code to the proper one.
i'm not entirely sure what to do. any help would be much appreciated!

It take time to change csc code.
Read this topic and change to XXV.
http://forum.xda-developers.com/showthread.php?t=2342328
so i don't understand a few things in regard to the steps...
1b. You are on stock ROM but is on other's region firmware and is rooted (based on Samsung official firmware). Same, just download your stock latest update firmware from sammobile.com first. Which contains your region's CSC.
Click to expand...
Click to collapse
so since my stock custom ROM is INU-based, i go and download the INU firmware?
2. Ok, now both are on a stock ROM but rooted, check your CSC using the CSC Changer app.
3. If not working, then install ES File Explorer from Playstore or link below (recommended) or other file browser with Root access ability. Open the side menu and select Root Explorer.
Click to expand...
Click to collapse
i only found one app in the Play Store with this name, and it's 0.99 cents, before i buy it, is that the correct one? or if i don't want to buy it, i just continue with step 3?
7. Alright all done, reboot your phone first. Then reset the BIN counter using Triangle Away. (Again, friendly reminder: Do not enter CWM Recovery again as it will increase the BIN counter) Reboot and put your phone in Download mode. Flash the stock ROM you've downloaded though ODIN.
Click to expand...
Click to collapse
so if i go with the ES File Explorer route, i can then go straight into flashing the Lollipop firmware?
also, do i need the app Triangle Away? if i don't care about the BIN counter?
my goal is to be unrooted, on Lollipop, with/without Knox counter tripped.
It doesnt matter INU or whatever region. As long as your device is N900 , Just download NJ3 firmware with XXV region which download link given in that post or download from sammobile.
Secondly, better to do factory reset after u flashed NJ3.
3. No need to buy csc changer. Just install free"phone info" from play store and check ur csc and if not xxv, change ur csc code to xxv with that "phone info" application.
4. You may need to flash NJ3 again or wipe data until u see ur csc is xxv.
5. Follow the instruction about lollipop post.
6. You can skip supersu 2.40 step if u dont want a root.

i ended up following the "new" method posted to the original topic. and just in case anyone finds this thread, here are the exact steps i took:
1. Flash TWRP via ODIN
Click to expand...
Click to collapse
i was using Odin 3.09. put your N900 into download mode by powering it off, then holding the Vol Down + Home Button + Power Button.
then within Odin, click on the "AP" button and browse for the "openrecovery-twrp-2.8.1.0-ha3g.img.tar" file, and click the Start button
1.1 Enter TWRP and create Backup. (To safe)
Click to expand...
Click to collapse
boot to custom recovery by having your N900 powered off, then holding the Vol Up + Home Button + Power Button.
perform a nandroid backup, and reboot the phone back into Android
1.2. Copy unziped file at /twrp/4d00279c40989079/2014-12-18--00-18-21 LRX21V.N900XXUEBNL4 to phone /twrp/xxxxxx/2014-12-18--00-18-21 LRX21V.N900XXUEBNL4 where xxxxxx is unique generated for your device
Click to expand...
Click to collapse
now that your phone is backed up, copy the extracted "TWRP-LRX21V.N900XXUEBNL4-samsungviet.vn.zip" to your nandroid backup location
2. Enter TWRP -> Wipe -Swipe to Factory Reset
Click to expand...
Click to collapse
boot back into custom recovery (holding the Vol Up + Home Button + Power Button.)
3. Return TWRP Home -> Restore -> Select "2014-12-18--00-18-21 LRX21V.N900XXUEBNL4"
Click to expand...
Click to collapse
select the extracted folder as your restore state
4. Select everything to restore
Click to expand...
Click to collapse
for me, there was only 3 choices to select, and they were already pre-selected.
5. When finish Restore, return TWRP Home -> Reboot -> Download
Click to expand...
Click to collapse
i had to power off the phone instead of using TWRP to reboot into Download Mode, then do the Vol Down + Home Button + Power Button.
6. Flash Bootloader 5.0 (without Auto Reboot) then pull out battery and re-enter download mode
Click to expand...
Click to collapse
then in Odin, click the "BL" button and browse for the "bootloader-5.0.tar" and click Start
7. Flash stock recovery (with auto reboot)
Click to expand...
Click to collapse
after pulling the battery and putting it back in. boot to Download Mode again (Vol Down + Home Button + Power Button)
in Odin, click on the "AP" button, and browse for the "recovery.tar" and click Start
8. First boot will take 5-10 mins.
Click to expand...
Click to collapse
voila. done.
BLUETOOTH FIX
Flash cwm via odin (dont tick auto reboot)
Take off batre and cable. And take on again.
Press volume up + home + power button and get in recovery mode (cwm).
Flash bluetooth dix from this forum (http://forum.xda-developers.com/gala...-roms-t2938607)
Get in the download mode and flash stock recovery.
reboot and you can use your bluetooth again
Click to expand...
Click to collapse
although i don't understand this step.
it says to flash CWM even though the previous steps have you flash TWRP. (edit: and then the previous steps have you flash stock recovery)
then it says to flash the ZIP file within the custom recovery, boot to download mode, and flash stock recovery?
any help on this part?
Just consider yourself that you are now using android L which is with stoch recovery after u have done all procedure. And yes u facing bluetooth error.
So u have to flash custom recovery( CWM) to flash bluetooth fix zip. May be u can use twrp again to flash bluetoothfix zip.

oh yeah, duh. step 7- flash stock recovery.
so i tried to flash TWRP again and i received an error in Odin. i'm thinking it's because i have to root again.
without root, i can't fix the bluetooth then?
I dont think u need root for that.
May be u change ur recovery to CWM than twrp and flash bluetooth fix

[Q] How To Make Samsung Galaxy Core 2 (SM-G355H) Good As New?

Hi! How do I make my device good as new like I just recently bought it? I am not just telling about hard reset. I mean EVERYTHING will be good as new, no records of roots or binary counters, restored to original stock firmware, whatever they are, I have no idea, ahahaha . I just want to know how to make it GOOD AS NEW just in case something went wrong with my device. Thanks in advance!

Hi,
In order to restore everything on your device as good as new, you must download the original stock firmware along with the pit file (if needed). You can obtain the firmware via either Sammobile or Samsung Updates. Don't forget to check your phone model before downloading. After downloaded, reboot your phone to Download mode then extract and flash the firmware via ODIN on AP. After the stock firmware installed, reboot to Recovery mode and select both Wipe data/factory reset and Wipe cache partition.
Hope this helps.

Is the firmware downloaded from sammobile safe? Can you teach me or give me a link how to use odin and will it conflict kies in my computer? Also, will these methods erase binary counters like triangle away?

Hi,
Sammobile requires you to register at their site, but it's safe and also fast to download. Besides the firmware and ODIN, you need the USB Drivers installed and Debugging mode to be enabled (by tapping Build number 7 times on Settings -> About device).
Files to download:
ODIN -> Click here
USB Drivers -> Technical Documentation | SAMSUNG Developers
After you obtain the firmware and ODIN, here is the step to use ODIN to flash firmware:
Extract the firmware and ODIN to anywhere you know.
Open ODIN, click AP button, and choose the firmware (in .tar.md5 format).
Hit start.
Firmware flash will take about 5-10 minutes. Don't unplug the USB cable or you will hard brick your phone.
After you see green RESET! or PASS, unplug USB cable from your phone and wait until recovery installs all files.
Don't forget to reboot to Recovery mode and choose both Wipe data/factory reset and Wipe cache partition.
After installing the stock firmware back, it's safe to update or connecting your device via Kies as long as your stock firmware is not modified (either by rooting or something else). And on your last question. Do you mean that this method will erase flash binary counters? If yes, probably not.
As a additional note, download the version that match your region code. So doing a backup of EFS partition is strongly recommended!
Hope this helps.
give me firmware link????????

Galaxy S7 G935F - Recovery root

Hi guys
Just got a brand new, G935F S7, would like to root and install custom recovery to install the dream S8 Port.
https://forum.xda-developers.com/s7-edge/development/root-proton-x-1-0-t3497772
I looked around, but found a few different versions of recovery and rooting options.
Is there a link i can jump to for the easiest, less risk way?
I have SM-G935F (Black Onix) and i have TWRP+Root and Custom ROM
Download:
TWRP -> Twrp-3.0.2-4-hero2lte.img.tar
Odin -> Odin
1. activate developer mode on the current system and turn on the option 'enable OEM
2. reboot phone mode to 'download mode' and flash using Odin (position AP) TWRP recovery [ATTENTION you must turn off autoreboot options in odin and after flash manually reboot the phone into recovery mode]
3. You can flash SuperSU or if you want custom rom with root:
3.1 go to options and select wipe data format - write "yes" then after finishing wipe necessarily restart phone to recovery mode [ATTENTION this operation will clear the memory of the phone without touching the data contained on the ex-scdard]
3.2 flash in the recovery file no-verity-opt-encrypt-2.2.zip
3.3 reboot phone to recovery mode
3.4 Flash your favorite rom and wait for boot up I recommend Ambasadii ROM..
Have a good day

SM-P550 No system

i have Samsung galaxy tab A s-pen and i have twrp on it i wanted to delete some data and i accidentally deleted every thing including system now if i try to power on my device it only thing that opens is twrp people please help :crying::crying:
if your twrp still working, what you need to do is get in TWRP, select download mode, then flash official firmware of your device. Before you do that, download official firmware here: https://samsung-firmware.org/model/SM-P550/
and then using Odin, flash it.
If you don't know all above steps, make sure you learn it, how to flash firmware using odin. there are good amount of info in XDA.
if you can only open twrp, then put a ROM in SD card and install it
https://forum.xda-developers.com/ga...om-samsung-tab-6-2016-10-1-lte-s-pen-t3525560
Download a custom ROM and move it to the SD card and then flash, or flash with Odin so that you can start fresh.
Personally I would flash with Odin so you can start fresh and not have to worry about any left over data or whatever that may interfere.

[Q] Cant flash Stock rom anymore

Hello everybody,
I got a Samsung Galaxy S7 Edge (SM-G935F) DBT version and flashed a Custom ROM (Firmware? idk the difference).
I did that like this: youtube.com/watch?v=_1ofpLHMVvA
Unfortunately there were a few problems there, like the camera is awful now (Bad quality and other camera apps didnt made it better).
So now I want back my Stock ROM. (Yes, Unfortunately I didnt made a Backup)
But I cant get it back, neither with TWRP or with Odin.
At Odin its stops at system.img and fails than and at TWRP I guess I used the wrong Rom because is said Zip file is corrupt!.
The following Stock ROM did I use for Odin and TWRP: updato.com/firmware-archive-select-model?record=2A12F0CE03CD11E7963AFA163EE8F90B
At Odin I unziped it and added it the right way: (BL, AL, CP and CSC).
At TWRP I didnt unziped it and used it like it is.
I hope you can help me there.
I have already made the following:
Changed USB Port
Changed USB cabel
Used Smart Switch
And yes, I can still install custom roms like LineageOS and Resurrection easily via TWRP.
Greetings, Darkatzu.

It is, because you will need no verity opt encrypt to flash too alongside official stock rom in order to use stock rom if you rooted by system modification method, with oreo 8.0 I think no verity zip is not working, so you need to flash latest nougat for your country/region alongside twrp , no verity zip and super su, you can download latest stock firmware for your region from samfirm application or updato, also download odin version 3.13.1, latest twrp recovery, super su and no verity opt encrypt from here on xda forums, first check and enable oem unlock, flash stock rom and then flash twrp through odin, then boot in twrp recovery and flash no verity and super su zips, to get detailed info on above steps search the forums. AND PLEASE TELL WHATS ASKED IF YOU WANT TO GET HELPED.
!! NOTE : IF YOU ROOTED FIRST TIME BY SYSTEM MODIFICATION METHOD, AND THEN INSTALLED CUSTOM ROM, THEN FLASHING STOCK ROM BACK WILL PUT YOU ON A DM VERITY ERROR. ALWAYS REMEMBER TO ENABLE OEM UNLOCK IN DEVELOPER OPTIONS BEFORE DOING ANYTHING!
HAVING OEM UNLOCK DISABLED AND THEN ROOTING VIA SYSTEM MODIFICATION METHOD, AND THEN FLASHING STOCK ROM WILL PUT YOU IN A HARD BRICK SITUATION WITH BOTH DM VERITY ERROR AND CUSTOM BINARY BLOCKED ERROR !!
As far as I know the above situation has no solution if you get into this mess and only a memory swap on board or some box can fix this. I know many users here on xda are stuck on this situation. Some users said they fixed this by using nand erase all and re partition using pit file options during flashing in odin, but I really doubt enabling these options will solve this if not making problems worse. Anyone is welcomed to correct me if the above situation has any solution. BUT THAT IS WHY SYSTEMLESS ROOT IS THERE TO AVOID ALL THIS...

I showed a Video Tutorial how I did that.
The reason why I did that, is for me: Not important.
And yes, I did OEM unlock.

Maybe you are using an older bootloader ? Can't say for sure whats causing it, the method you used above I think required system modifications, but you are using a march 2017 stock rom, so it looks updato don't has V2 bootloader firmwares for DBT, problems may happen when flashing an older bootloader on a newer one, it could also be your pc or other hardware problem, but in case try again and download samfirm from here : https://forum.xda-developers.com/attachment.php?attachmentid=3803841
Enter DBT as your region and model SM-G935F , it will download the latest stock available, be sure option for auto decrypt, check crc32 and binary nature are ticked.
After that check oem unlock and usb debugging is enabled and follow the steps :
1. Put phone in download mode, use original usb cable, and make sure pc usb port is working correctly. Also phone must be charged above 50%.
2. Download odin 3.13.1 from here https://forum.xda-developers.com/attachment.php?attachmentid=4431597&d=1519662712
Latest twrp available https://eu.dl.twrp.me/hero2lte/twrp-3.2.1-1-hero2lte.img.tar.html
Latest no verity opt encrypt https://build.nethunter.com/android-tools/no-verity-opt-encrypt/no-verity-opt-encrypt-6.0.zip
Latest stable super su https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.82-201705271822.zip
3. Put phone in download mode, extract the firmware downloaded above from samfirm tool and put the respective files in their boxes, use CSC and NOT HOME_CSC. Make sure no option other than F.reset time is ticked in odin options. Begin the flash procedure. After it is completed, don't reboot and place twrp zip downloaded from above in the AP tab of odin. After it is completed, stay in download mode and hold power+home+vol down to reboot from download mode and immediately switch to vol up button to boot in twrp recovery menu.
4. In twrp recovery menu, you need to swipe for system modifications or tick read only ( if you previously allowed for system modifications then you can do it again it doesn't matter, but if you previously didn't swipe for system modifications then tick read only and download systemless zip from https://forum.xda-developers.com/s7-edge/development/samsung-systemless-devbase-encryption-t3517178 )
I will recommend this as you won't need to flash dm verity.
5. Now, go to wipe> format data in twrp recovery, after its done, flash super su and system less zip through twrp to get system less root if you don't want to get dm verity error hassle when flashing stock roms OR flash super su and no verity opt encrypt if you already have allowed system modifications. After that reboot. It may take sometime.
Also to note if you never allowed system modifications before in twrp, and you don't want to root either, then you can safely flash stock without flashing twrp or going through further steps.
This is what I could best explain according to my limited knowledge, if you still fail to flash stock in odin, then I am not sure it may be your pc or other hardware problem and you may need a repair box, try checking on another pc or some expert user to help. Good Luck.
These steps are only for installing stock rom back on previously rooted S7 edge devices using custom roms and for rooting a stock rom.. and only applies to SM-G935F

As I already said: As I did. (both)
I already tried with samfire.
Same error.
Sorry I couldn't be much help. Does it always stucks in odin at system.img? Looks like its a hardware problem in your pc/usb ports or phone's usb jack. Try getting your phone checked by a repairer, flashing from another pc or changing usb cable. Also try running odin as an admin or try with an older odin version. Good Luck

And I can flash TWRP via Odin without any errors.

And yes, I changed PC 2 and yes tryed other versions of Odin LIKE where AP is named as PDA.
Strange thing if you could flash recovery but not the stock rom, looks like you need to get it checked by a tech. But as a last resort did you tried using pit file and repartition ticked? To get the pit file extract the CSC file and you will find .pit file there, open pit tab in latest odin and select that pit file, then tick repartition box and proceed to flash with all other files selected in their respective boxes. If its still the same then I guess I can be of no more help. Cheers !
!! Warning : Using pit file is never recommended and it could brick your phone permanently if there is any power outage/usb disconnection during flashing with pit, it is used to correct file system partitions if they are changed/corrupted. Its better to outweigh benefits with potential danger. Also a pit file will erase all partitions first, then write flash data from beginning and if you again stuck at system.img when using pit file, you will be left with a permanent brick. So I will recommend to get it checked by a tech if you want stock rom that bad and don't do any risky thing with your pricey phone
