[Q] My galaxy stays in "S" logo and vibrate, what can i do?!

i am now using the ZSJPG 2.2.1 version.
i use this version for few weeks already and there is no problem...
but yesterday i failed to turn it on and it stayed in "S" logo and vibrated....
so far i know 3 ways to solve this...factory reset, flash a rom or flash the original kernel...
but i want to keep my data and files!! which one is better??
thanks to everyone!
many thanks!!

I too have a similar problem ! I tried re-flashing. it doesn't help. When I go into recovery mode, It says " update media, please wait E:cant mount /dev/block/stl10 ( invalid argument) E:copy_dbdata_media : Can't mount DBDATA :
your storage not prepared yet, please use UI menu for format and reboot actions.
copy default media content failed. "

you mean you failed in both re-flashing rom and kernel??

Now it works.. Peculiar!
I was on I9000XWJV1 .. wanted to go back to I9000XWJS8. Tried JPY as well .. Was having the above mentioned problem. Now I flashed it again with JV1, now it works fine.
Could someone explain this ?

Thanks for helping me walk, the phone unlocked y frp unlock, having prepared in the card the dload b136, when I flash the c432 oeminfo from the twrp 3.0.2.0 b361-b378 Appears on the screen:

Try to find a solution through the program SRKToolHuawei-Lod-Chong-V2.0-20161002 (ALREADY I SAW IN A VIDEO THAT ENTERS THE EMUI RECOVERY)

5º I use the program SRKToolHuawei-Lod-Chong-V2.0-20161002 with the step 1 to unlock the bootloader since with that step it directly enters emui recovery in a video that I saw, (BUT TO ME MEET TWRP 3.0.2.0) (WITH THE 3 BUTTONS DOES NOT ENTER, IT IS ON THE HUAWEI LOGO)
Other data that do not explain if I am not mistaken .. in the bootloader appears depending on whether I enter the from the twrp:

What am I doing wrong because of my lack of experience and knowledge, can you help me?

First flash the same firmware that you had to restore ur phone to a working stat.
In srk tool flash stock recovery.
Find the firmware for ur phone and extract the zip,you will get a file update.app ,copy this file to a folder name 'dload' on ur SD card.
With the phone off,press 3 buttons,power volume up and down till the update start.

I already did it, it does not want to enter, it does not decide to enter, it must be damaged recovery, it does not enter for much that I try with the mode of 3 buttons, it must be wrong recovery emui, no Never comes the emui symbol, only the symbol of huawei, desperate, helps, Can post me some kind of complete help to follow, miss recovery miui

What is not entering?
To boot into recovery,you need to hold volume up + power till you see the huawei logo than remove power key and keep pressing volume up.
Remove any usb before doing this.

Not enter, I already did without usb, turning it off, many times, waiting for the vibration to release the power, and also with the 3 at the same time, there is no way to get the miui logo, the huawei continuously, no I have android start to work ... when I put the dload it well, in the sd card, I feel alone in this problem .. And there where the problem (internal), related to the twrp, must be interfering, my Lack of knowledge, any other method to follow? How to completely erase recovery and re-flash?

Sorry I don't understand what you did and what you use and which firmware.
Do you have unlocked bootloader? Do you have twrp installed? Can you boot twrp?

I have unblocked the bootloader and twrp 3.0.2.0 b361-b378, I explain something important about what twrp 3.0.2.0 b361-b378 shows, once having the twrp, when I unlock with the SRKToolHuawei step 1 instead of going to Logo de miui, it is directed to the twrp, when it is done with 3 buttons it never enters, it stays in huawei logo

1-First boot to twrp, wipe format data,it will ask you type yes.
2-aftet wiping data in twrp go to first page and press reboot and reboot recovery.
3 Flash this in twrp ,copy this 2 files to sd card so you can install.

http://update.hicloud.com:8180/TDS/...3574/f1/full/hw/eu/update_data_full_hw_eu.zip

I really appreciate it, this aside, inside wipes in the twrp comes this when doing wipes
formatting cache using make_ext4fs...
qipping data without wiping/data/nedia...
done.
updating partition details...
Failed to mount '/ product' (invalid argument)
Failed to mount '/' vendor '(invalid argument)

I will follow his indications to the letter of what he said to me before, I will communicate you here.
Formatting and say if this appears ...

you may need to reboot recovery to be able to use / data again.
updating partition details
Failed to mount '/ product' (invalid argument)
Failed to mount '/' vendor '(invalid argument)
Failed to mount '/' version '(invalid argument)
...done

In twrp " format data "not wipe cache. It should ask you to type yes to confirm.

Leave this... I already did

Ok reboot to twrp recovery and flash the 2 files above.

Agree to take time to proceed.. it is downloading, is slow.. you are being of great help to the community and laggards that can happen this

Unable to mount /vendor /product /version

Hello everyone,
First off all, Im not very experienced with all the android stuff, so I tried to flash some custom rom on my Huawei P9 but before flashing I did an andvanced wipe on my TWRP 5.1.0-.0.
The problem is, that I peace of s**t wiped all options, from Davlik/ART Cache about system to version.
I luckily did a nandroid backup before do this, so I restored it but now Im getting the failure every time I try to flash the custom rom or do a factory reset...
Failed to mount ´/vendor´ (Invalid argument)
Failed to mount ´/product´ (Invalid argument)
Failed to mount ´/version´ (Invalid argument)
On every boot it restarts to the eRecovery, what should I do?

If you can still get into TWRP then try flashing the backed up (or stock, extracted from a stock ROM) boot.img first. This will bring those partitions back (I think). Don't do this with the restore method in twrp, instead use the install button then change from .zip to .img.
Have you tried the dload method to flash back to stock or the huawei updater and hisense? Then redo everything from unlocking the bootloader to installing twrp and root. From there try to restore your backup. As far as i know this should work if all else fails, having done the exact same thing myself as you previously.
In the future when installing a custom rom the only partitions you need to wipe for a clean install are
Dalvik/ART
Cache
System
Data
Internal Storage (optional)

Only if you were on b378 before you messed up the phone or plan on flashing a b378 based ROM. Otherwise you will have to download a stock firmware and extract the boot.img from there. You can find stock firmwares in this thread:

Same Problem with Huawei Honor 8 FRD-L04
Having the same issue only without these vendor, version, etc mounting, nothing will flash...including stock. Bootloader works, TWRP works, cant mount, repair, or format partitions. This happened after flashing Revolution I believe. If anyone has a walk through for a potential fix, I'm all ears!

Sorry to say you but there was no solution for it. I did send my phone to servise and still wait for call.. in theory fix should be easy (with their tools etc..) but i am still not sure will they fix it or not.
When they call me i will tell you how much it cost and what they did to it..if they could. Worst case scenario i will sell my phone in parts and get some money back.

Every few days somebody opens such a thread, having the phone similarly bricked. When asking what did you do, it turns out that he was on some of the AOSP based custom ROMs (there are couple of them), and he wanted to go back to stock, or he wanted to try/flash to the other custom ROM, etc.
I really wonder (I never tried those AOSP based custum ROMs - AFAIK, drivers for camera are not published and all those AOSP ROMs cannot utilize the main strength on this phone, the camera. Besides, I'm happily using another custom ROM that is stock based [hence havint the stock Camera app] but debloated, prerooted by Magisk, etc) do the corresponding AOSP custom ROM threads provide FAQ or information how to go back to stock (maybe they do but people don't bother to read)?
If they don't provide such info, why people do not first ask there (before bricking the phone)? IMO, developers of those custom ROKs would know the answer, if asked (supposidely they test their custom ROMs on various configurations and they have to go back to stock and forth to custom).
It will be helpful to ask and to get the answer in those threads for future users who will similarly come to try the ROMs, but maybe then also want tto go back to stock - to prevent that they similarly brick the phones.

Do not worry. First when u r in twrp wipe your system , cache, and dalvik cache partitions. Then extract the big update.app file and extract the boot, recovery and system images. Then flash recovery first and boot image and system image using fastboot. Then take a microsd card create a folder dload and place the big update.app file inside it and put it in ur phone.
Now press vol up vold down and power button till u see the huawei logo.
Wait for some time. You will see the device starts updating. After the update finishes reboot phone.
There you go phone starts working. Now huawei logo will flash for some time. If it is taking too long go to recovery by pressing vol up and power then do wipe data and cache. The process might fail but no problem press reboot and your phone will work.

TWRP builds for P9 Android MM, N, O
TWRP must be ported to the particular device and firmware to support its partitions set-up, encryption, etc
No wonder that installing inappropriate TWRP and using it to flash something can brick your device
For Huawei it means that different ports of TWRP are required for different EMUI versions (4, 5 or 8)
In other words, depending on your P9 stock Android version, the following TWRP builds are proven (and AFAIK the newest)
- For Marshmallow, P9-EVA-TWRP-Android-6 from this post:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
- For Nougat, twrp-3.1.1-1-eva_extended from this post:
https://forum.xda-developers.com/showpost.php?p=75787111&postcount=1
- For Oreo, P9-EVA-8.0.0-TWRP-v4 from this post

I managed to fix this. My P9 was bricked, fastboot display an erro(11) and the above when trying to flash a rom in TWRP.
First download a stock rom, if possible the rom version that came with your phone, unzip update.zip to get update.app. Download app extractor and extract vendor.img, product.img, verlist.img, system.img then flash all img in fastboot, i.e., fastboot vendor vendor.img..
Erecovery mode will now be possible, connect to wifi and recover phone.

Bro today i found solution for this problem i was also getting error i was very frustrated
first of all download the original firmware from the manufacturer and unzip all the files you will find many images file such as boot.img,vbmeta.img...etc extract all the img files from the rom and place it in your desktop.
then whatervr invalid arguments you were getting such as vendor product etc this all comes inside the SUPER.IMG file you have to do only one thing go to fastboot mode and flash super.img file while booting your phone in fastboot mode
command:
fastboot flash super super.img
then it will take a while and congtrats all errors fixed after struggling and searching almost two hour i didnt gat a way out i wan not able t copy super.img file directly into storage i dont know why but after this the phone became normal
if you face any issues then tell i will send screenshots of everything

need help

I just bought a P9-L19 International that comes with MM. I do not what I did while trying to root the thing, but I end up with the following problem:
Every time I try to install something from TWRP, it always says:
Failed to mount ´/vendor´ (Invalid argument)
Failed to mount ´/product´ (Invalid argument)
Failed to mount ´/version´ (Invalid argument)
Since I do not know which version of MM it comes with, I tried many roms. Right now, I have EMUI-A168-L19C900B040SP11. Although it seems to work, I do not for sure whether it is the really the right rom. I can install and use TWRP, but every time I try to root it with SuperSu, TWRP always returns the above error messages and the flashing fails. So, I can't root my phone now. Any help with fixing the problem/id the right rom/root is greatly appreciated!
Thanks!

System Status: Custom
RMM State: Prenormal
FRP Lock: OFF
OEM Lock OFF
Secure download enabled.
Also my Knox is 0x030c.
In recovery I get this:
Code:
#Fail to open recovery_Cause (No such file or directory)
Stock/Combinations flash fine. But on reboot they boot into stock recovery and gives this error:
Reboot Recovery Cause is Unknown
Support SINGLE-SKU
File based OTA

(A lot of times)
Any ideas? I really miss this phone.
Thanks in advance!! I'm on CRGA if that helps, So I can flash ARG1 combination, CRG1 firmware, CRGA firmware.

I had no issues with EFS before at all, All issues came after this backup restore.
Flashing custom recovery gives me this: imgur.com/a/zKcoJVp

Have you tried formatting data, where you have to type yes? I believe TWRP still has mounting issues, so you have to format like I said, then TWRP should mount properly.
You will have to flash stock with Odin to get rid of the binary issue., I believe.

I was just trying to make sense of your post if I'm honest.
If you can not flash stock with Odin, contact Samsung for repair.

Well, take it to your work for them to sort it out, just don't tell them what you tried to do.
Surely they would get you a replacement?

How did you restore your efs partition?
Bootloader 4?
PM me.

I am starting to think it's a hardware issue and this might be how it should be done..Problem is it says System Status: Custom, And I can't change it to Official without booting :crying:

Ok stupid question.
Since your on bootloader v4 since your on crga
1) did you flash any firmware with 4 in like N950FXXU"4"CRGA because you can't flash bootloader v. (3 or 2 or 1)
2) Have you tried the latest Odin?
3) have you flashed the CSC file (this one erases files and set up like new phone) instead of home_CSC?
And since Knox is Tripped there is no going back! So hope your company doesn't mind a rooted phone.
You'll need combination files that's for N950FXXU4CRGA (pay attention to the 4) if your going to flash combination files.

You 2 read my post entirely, I am limited on only stock recovery and stock ROM, I can't even boot stock ROM. So that fix if it's the data one is useless

Ok I have read it, you can't use that method as you are not allowed to flash twrp and that method needs to to have twrp installed.
Last option before sending service station
Flash pit file and tick re partition
You can find pit file by extracting csc tar file

I tried that, I got many solutions I want to try first, I still don't know what exactly went wrong for my device to do this, What will Service station say to "System Status: Custom", I can't reset it to official when I can't boot.

The pit file included into the CSC file don't will be used while the firmware flash process?
