S8 recovery mode problems - Samsung Galaxy S8 Questions and Answers

Hi, when I boot into recovery mode I see the following message: #fail to open recovery cause(no such file or directory)#
My S8 (sm-g950u1) has been flashed stock firmware (crk3), is not rooted and boots fine.
Also, when I tried to install an update from sd card (named "update" and placed at the root of the sd card) I get a failed to verify signature and "error 21."
Thanks in advance

for signature problem try clockworkmod recovery (try there option disable sign)
or download file again may be it is incomplete or sign missing
Are you sure you have a recovery image installed other than the stock one?
Try 1click root & recovery script from maverixx.
It`s very useful for for rooting and reflashing recovery, and You will see if there is any error.
1. Download RootTattoo1Click_Recovery_2010-03-18_Mvx.zip from http://forum.xda-developers.com/showpost.php?p=5835675&postcount=1
2. Extract rtattoo folder to C:/

[Q] No fastboot only adb on TWRP

Hello
I think the phone is bricked but I'm trying anyway...
Only adb is working but i can't copy zip file on the phone
"failed to copy 'LG-G2_D802-StockMOD_v1-01.zip' to '/sdcard/rom.zip': I/O error"
It works for small files... great
Everytime I reboot in recovery mode it's like he lost everything on sdcard, even on / if I put a zip, nothing stay after a reboot
If I put CM in / for exemple and I try to flash it I've got :
Updating partition details....
E:Mount: Unable to find partition for path '/cm.zip'
Error flashing zip
Updating partition details....
If you can go to download mode, just go back to stock. In general section.
Can't back to Download mode :/

You can't write to any /system folder unless you flash the switcher zip that flashes recovery to the boot partition and the bootloader to the recovery partition.

Downgrade to Marshmallow

Hello Friends, I just upgraded my Zenfone 3 ze520kl to Nougat, but i prefer Marshmallow i try from recovery mode to flash Marshmallow, it shows error and the installation aborted. Can any one help . Thanks.
What error does it show?
Error with some numbers follows by 'install aborted'. I unable remember the error numbers. I did three times all the time with same remark.Thanks.
That's not very helpful. Can you try it again and tell us exactly what it says?
Hi,
I downgraded a few days ago, here's an overview of the steps.
WARNING, this requires a factory reset so you will lose the data on the phone, so make sure you have backups before you proceed. You do this at your own risk and I am not responsible for any damages.
I assume you have adb / drivers all configured and know to how use them.
1) download firmware file http://dlcdnet.asus.com/pub/ASUS/ZenFone/ZE520KL/UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip and save to SD card / insert card in phone.
2) download recovery and boot img files for Z017D_WW_13.20.10.152
- https://mega.nz/#F!ok0V0RIA!5WKtHe98opzjVI3NPbM7Ww
- under the folder Z017D_WW_13.20.10.152
3) Go to fastboot mode (power + vol up)
- flash recovery.img (command: fastboot flash recovery recovery.img)
- flash boot.img (command: fastboot flash boot boot.img)
4) reboot to recovery (power + vol down)
5) install update form micro sd card.
set the file UL-ASUS_Z017D_1-WW-13.20.10.152-user.zip that you saved earlier
6) wipe cache
7) factory reset
If you don't do a factory reset and reboot, Android pretty much crashes on multiple processes on start up, it is unusable.
Regards,
TK

Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.
Same thing happened to me as well. I just went ahead to flash the RAW file (http://www.asus-zenfone.com/2016/12/asus-zenfone-3-raw-firmware-and-asus.html) and updated the software to the latest marshmallow update, followed by a factory reset.
If we Downgrade
Then we get update in future yes or no??
Sorry for bad English??
Yes.
Hi, thanks for the help. Please answer this:
Do I need to use Recovery and Boot.img the same version of ROM? Why?
Why do I need to install Boot.img?

E:signature verification failed

Hello
I rooted my TAB 2 P5100 with "CF-Auto-Root-espresso10rf-espresso10rfxx-gtp5100.tar.md5" through Odin 3.0.7.
It all finished OK and As i Check through Root Checked it says that my device is Rooted and it still has the latest original Android version 4.2.2
As I go to install any possible ROM I can find through SDCARD I recieve the error displayed in the title.
E:signature verification failed
I read a bit around and I wast to add that I do not have the option to toggle off verification mode.
Any help PLS
Thank you

NVM, it was easier than what i thought.
Download TWRP.zip and place it on the SD card
install TWRP fropm Google APP
Open it and tell it to install the TWRP.zip into recovery.
shut down and start to recovery - which starts to TWRP
after that is very easy.
