boot freeze after flashing twrp:

0. I've flashed G935FXXU1DQH5_G935FAUT1DQH1_AUT

and followed the instructions on the first post:

1. enabled OEM Unlock and USB Debugging

2. flashed twrp-3.1.1-0-hero2lte.img.tar using odin

3. adb sideload BETA-SuperSU-v2.68-20160228150503.zip

4. adb sideload no-verity-opt-encrypt-5.1.zip

boot system

freeze at samsung logo. (I've waited for more then 5 mins)

I've also tried to flash the rom again and just flash twrp (2) and tried to system boot but it still freezes.

I've also tried to wipe everything, it doesn't help.

If I try to flash older rom with Odin (G935FXXU1DQE7_G935FOJK1DQD1_ILO) then it would fail to flash (before I flashed the newer rom I could flash this rom, so I guess it is blocked by the new BL?)

Help please.

Hi friends. Please excuse my English (bad knowledge and Google) I would like to ask how do I restore the TWRP backup if I upload a new rom? Understand, I now have ROM QEI and I'd like to upgrade to QH5. If I flash through Odin, everything will be deleted. I have a custom splasch screen and a bootlogo. different settings and I'm too lazy to set everything up. I would like to flash a new rom, upload a TWRP and a flash backup, or part if it goes. I have found many wonderful advice, but I have not found it here.

Cannot install TWRP on SM-G935W8 with Nougat

I am trying to root my Galaxy S7 edge which I just recently purchased and I have been failing miserably.

I went through the steps of installing twrp. I used odin version 3.12 and twrp-3.1.1-0-herolte.img.tar. After flashing when I try to go into recovery, the screen turns red and goes nowhere. I tried couple times, where I first re-flashed AP part if original Bell firmware followed by twrp, but I got same results. I also tried different versions of twrp. I tried all the versions from 3.0.0 to 3.1.1. I got either red screen on newer versions, or message "recovery is not seandroid enforcing". In either case flashing wasn't successful. I usually gave it about 10-15 seconds before I restarted it again in download mode.

When I tried to downgrade to Android 6 followed by twrp, but I got a same red screen in recovery.

I also tried CF AUTO ROOT method, but it wasn't successful either. I got "recovery is not seandroid" error message at boot up and then a black screen appears that says "verification has failed reset smartphone to boot normally" and a reset button is present at bottom. After reset all changes are wiped and no root.

I need root to get my Titanium backup going and to restore content of the old phone. I have done lot of reading and googling but I couldn't find any solution or explanation why I am failing.

I also wanted to mention that I am not the original owner of the phone and the phone is unlocked. I am not sure whether unlocking procedure could lead to issues installing twrp.

If anybody can point me to right direction how to overcome those issues I described and get phone rooted your help is very appreciated.

From what I read, after installing TWRP I have to wipe data. Before wiping, can I backup data and restore after flashing superSU and dm-verity? Does it conflict in any way with the root process?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] ampirz007:
your bootloader is locked so you wont be able to root your phone (yet). :(
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] force70:
Its not locked he has a bell phone and it has exynos not snapdragon...the thread title is pretty clear saying EXYNOS anyway

the 1st post is clear about exynos only and not snapdragon

the 2nd post clearly states not to use on snapdragon.

In other words youd have to be an idiot to try this on a snapdragon lol.

But the red screen he mentioned is new to me...wish i could help but something is clearly odd

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] lilrevuk:
Hi, was wondering if someone could help me out...

Flashed a few devices before, but this is the first time I've played with my S7 (G935F).

Downloaded ODIN, latest bootloader and modem from Tkkg1994's page and followed tutorials to flash all 3. Problem is, I can't get out of download mode. When I restart the phone it goes back to download mode without the info at the top of the page. Odin still sees my phone, and will flash the bootloader just fine, but no matter what I do I can't get into recovery to see if TWRP is installed.

Any help would be greatly appreciated,

TIA
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] cavinrocks:
Shouldn't you have used twrp-3.1.1-0-

hero2lte

.img.tar ?

Why did you flash bootloader and modem and not just the TWRP Custom Recovery, like explained in the first post? Did you disable Auto-Reboot in Odin?

Some problem for me, but previous version works fine. I think last one is buggy.

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] robsonr:

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] cavinrocks:
The question with the bootloader wasn't for you, it was for lilrevuk. :eek: Your question is, did you flash the twrp-3.1.1-0-herolte.img.tar (S7 flat) or the twrp-3.1.1-0-hero

lte.img.tar (S7 edge)??
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] voroxda:
In my experience that is not true! A stock bootloader does not boot into a custom recovery. You have to flash the suitable bootloader too.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] cavinrocks:
What :eek: just trying to help here, mate. Nevermind, I used the tutorial and everything worked fine for me. No bootloader, just TWRP over adb. And we will never know, what TWRP was used by robsonr.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] voroxda:
I agree to everything you have written. Of cause TWRP must match too. I can only say, I was in the exakt same situation: no chance to boot into recovery. no chance to boot into system. After flashing the bootloader, which was part of the custom ROM which I want to install afterwards, a boot into recovery was no problem any longer. May be it depends on the installed bootloader (version,branding..)?

PS. Most important is also the OEM unlock status.

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
So I started reading the procedures and downloading files for rooting my 935F. But I stopped here as I read a few steps which are unclear so I won't proceed unless I'm sure about the following questions that didn't apply on my previous phones:

1. I see 2 different steps for root (a. use the SuperSu flashable zip, b. generate CF-Auto root for your specific ROM version from ChainFire site). Which one to use and why not the other?

2. I read that if my data is encrypted, the procedure of root will wipe my data partition but I don't have time for this. Then I read that by default all phones data partitions are encrypted. So is my phone encrypted or not and how can I find out in order to avoid data wipe?

3. I read also that you cannot just root and keep your stock ROM to work on it as a base. You need a modified kernel otherwise your phone doesn't boot. So which is true. Can I keep all stock or am I forced to use custom kernel and since I do so, I also use custom ROM?

[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
Thanks. Very clear answer. About 2 though, i haven't seen any step on how to decrypt and since i haven't encrypted anything myself, i don't know where to look. Or does this imply that during root I choose to format data and setup phone from scratch?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] Ferenor:
Mmm thank you. Honestly last time I tried I had some problems... Probably because I didn't format the data partition, cause it was giving me an error on the recovery. Will try again.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] jrjully:
Good morning guys,

I have an S7 935F, but I can not do TWRP recovery

I have already seen some tutorials, I already did the OEM unlocking and even then nothing.

The procedure is complete and I can enter the menu of Recovey, but my device of the error and does not start anymore, then I have to pass the ROM.

Help!

Sorry for my bad english
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
From my understanding after reading almost the whole thread, I realize that decryption part that is mentioned at some places but NOT in the main instruction steps, is the step where you format /data partition (if yes, that should be clearly stated in instruction steps if it is so crucial). Please correct me if I'm wrong. But if I am correct, I guess I am also correct in the following case where one needs to stay rooted with stock ROM and kernel. In that situation, whenever there is a new OTA update, root will be gone, the new update will encrypt /data again and by repeating the rooting procedure, you'll have to format /data again. That means complete setup at each OTA. Am I correct? cause if that's the case, it may be more worth it to follow a custom ROM just to avoid this whole step since with custom ROM you'll a=only flash /system.

Please correct any mistakes in my explanation above.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] mrsmtt:
Certainly, as you said, decryption = format data partition; I'm not sure about the OTA thing but I know that if you're on stock ROM and rooted you can update through SmartSwitch whenever a new update comes out and you'll loose (forgot to write this) root by doing this so maybe it might be possible even updating just through the phone.

I'm afraid that if you do so you'll need to do the whole process again including data format so yes, it's definitely better staying on a custom ROM since you've already tripped know there's no advantage on staying stock.. at least this is my opinion ;)
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
Too sad but i thought so. Well, my 10 year experience with custom ROMs is that they usually carry a few bugs and you enter an infinite circle of waiting a newer version that will fix the bugs but will trigger new ones and by the time your device gets a bit older, most devs stop development so you stay hunging with an old base. I decided never to use custom rom again and in fact i even kept my phone stock without root for the first time in my life. I'm still thinking whether i should proceed. I definitely need my old root capabilities but i don't want to enter this time consuming circle of reconfiguring from scratch every time there is an update
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] mrsmtt:
If I were in you I'd wait since the oreo update will bring the new UI and probably will require the stock firmware to upgrade so at this point it's worth waiting and then if you decide stock isn't enough for your needs you can always give a try to some custom roms; I must say, in the past I've been in the same situation with my HTC devices.. bad ROMs, lot's of problems like I couldn't even manage to call someone but here, people who "works" for the s7/edge seems to know what they're doing! Custom ROMs are pretty stable at the point that I don't regret being stock at all :victory:
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
Oreo won't come to us soon. Wait at least a year or more. 7.1.2 should already have arrived to us but it seems it will take months instead. Since there is no announcement at all, i guess it will take even more
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] andreasy:
I don't know but I did what we said here, which is flash TWRP, enter recovery and flash SuperSU, I selected to allow changes by swiping right since I would install SuperSU, and then tried to format /data as discussed but it cannot be mount for formatting. After that stack in boot. Extracting stock now to fix but if that's the case then what else should I do if formatting data is not possible?
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] force70:
You are supposed to format before rooting dude not after.

Flash twrp and format data, reboot twrp then flash SU.

This has been the procedure for over a year now, the only change is you dont need to flash dm verity if rooting as its built in to SU and magisk.

I purchased my S7 edge b4 it came out. This is the last phone I ever purchase without knowing 100% that I can root it. It's disgusting how much we pay for our phones and then have restrictions. Yes, I may be on a network (that I pay for) but I dont call in for "support". If the support thing is a real concern, the providers can ask what OS ppl are running and inform them if they req assistance, they need to run x. How many ppl actually call into a providers support with a rooted phone or custom Rom anyway? Those ppl have no business doing anything to their phone..

Hi, I'm having a problem with installing on my s7 edge. I followed the instructions on the first post, but my device will not boot up. The only thing that I can think of is I download twrp from the Americas link as the european link is dead.

---------- Post added at 07:25 PM ---------- Previous post was at 07:23 PM ----------

By the way, I'm using the odin install as I was planning on installing Batman and using Magisk for root.
[Samsung Galaxy S7 Edge (Exynos) ROMs, Kernels, Rec] impBerlin:
Had the same issue.

Very important: You shouldn't reboot when you installed twrp by Odin.

Install by Odin in Download mode then go directly from download mode into recovery mode.

In recovery either you install a SU tool like SuperSU or Magisk if you want to root.

Else use the dm-verity fix and install this instead of a SU tool.

Important is, that you go directly from Download mode into Recovery (into twrp) and install one of the mentioned patches. The SU tool installation will patch your boot loader and will boot normal.

I couldn't manage it to keep my /data partition and was forced to wipe it in twrp. Maybe it will work on your phone without wiping your data.

This is for sure. You can install from SD Card

What I have done so far:

... Flashed latest firmware ... and did a factory reset (plus wipe cache partition). ... Flashed Auto-Root again. Waiting 9 Minutes. Flashed bootloader and recovery file provided by chainfire as it seems like it really does not work this way. Guess there is something wrong with chainfire's stuff. Maybe I need to disable autodetection option when generating Auto-Root file for my device. Waiting another 13 Minutes. Flashed the whole firmware again. ...
