If you connect your device to kies/smartswitch it will repair your device but you will lose your data. You may not be able to recover your data but you can try backing it up in recovery before you repair the phone. Any version of Odin should flash recovery for you

Try removing the battery!
Or the best thing is you do a full wipe in recovery and enter download mode and then flash any stock rom!!
And then flash any kernel for recovery! Mine is uc v9!!
This will fix your problem..

It won't let me wipe data/factory reset
it won't format /cache & /datadata !
your subject and words are two different things. you are going into recovery and attempting to flash a zip, but it fails. your subject said your phone won't start, and instead goes into recovery.
don't take offense, but "all bases have to be covered" since you're a new member, so:
do you know the difference between recovery and download mode?
how many times did you try going into download mode? it doesn't always happen on the first attempt.
if it's still failing even after 5 very careful proper tries that would put another phone in download mode, did you try removing the battery? how long did you remove the battery for before trying to go to download mode again?
Try again. Boot into downloading with volumedown+home+power

4) Click Start (Wait till it Says Pass) (Ur Phone will Restart to a Black Screen)
5) Remove & put ur battery back to ur phone.
6) set it back to Download Mode
7) Click Reset in Odin (Re-Partition should be unchecked).
8) Click PDA button and select this file: CODE_I9003XXKPE_CL409735_REV08_user_low_ship.tar.md5
9) Click PHONE button and select this file: MODEM_I9003XXKPE_REV_00_CL1041909.tar.md5
10) Click CSC button and select this file: GT-I9003-CSC-MULTI-OXAKPE.tar.md5
(Auto Reboot & F. Reset Time should be ticked/Checked)
11) Click Start.(Wait till it Says Pass) (Ur Phone will Restart, wait till ur phone starts shows the settings page. then restart to Download Mode)
12) Repeat Step 1 to 11
13) Click reset
14) Click PDA & "Select I9003XXKPQ_I9003XXKPQ_I9003SERKPQ_HOME.tar.md5" file
15) Click Start. (Wait till it Says Pass) (Ur Phone will Restart, wait till ur phone starts shows the settings page)
16) Done.
Required File
1) Odin & "latona_20110114.pit" files Attached
2) XXKPE & XXKPQ from here
Thank you everyone for your help
actually, I noticed a post here on the forums saying that if I remove the battery, press the combos, then insert the battery while pressing the buttons for download mode.
I tried it & it worked !!
I flashed JPKP5 since it has arabic support then flashed cf root
Everything works fine now I have a rooted phone, trying to flash MIUI on it.
Hope it works.
Thanks again guys for helping I really respect.
Can't find alternative download link.
I have searched the internet for any other download link for xxkpe firmware (since hotfile is closed) but could not find any. I will be very thankful if anyone of you could provide an alternative working download link.
Greetings;
Go to Sammobile website. Search for your device and then pick the ROM you need.
Alternatively I recommend DDLF2 Full ROM. (Found in XDA Forum)

Help Needed

Well , Hi everyone
I will try to be detailed as possible
First of all I used this Guide to reparation my Xperia L 2105 and it worked perfectly .
I stayed on a custom rom for a month until I decided to flash the Stock rom again (silly me)
While flashing and just before it finishes flashing I encountered an error (but I don't remember it)
tried to switch on the phone but there was nothing , just a black screen and when I tried to charge it there was a red led light but no charging .
So I entered the fastboot mode and flashed a kernal with CWM , the device charged normally while the device is turned off and the buttery indicator appeared on the screen. and when switching on normally it stuck at SONY logo
After charging , I entered the CWM recovery and tried to flash a custom rom from SD card but a list of errors appeared.here it is
E:can't mount / cache / recovery / command
E:can't mount / cache / recovery / log
E:can't open / cache / recovery / log
E:can't mount / cache / recovery / last_log
E:can't open / cache / recovery / last_log
E:can't mount /external_sd/
and when flashing the stock rom again using flashtool that's what appears
- INFO - Ending flash session
- ERROR - Error in processHeader : 22 : The device does not recognize the command.
- ERROR - Error flashing. Aborted
- INFO - Device disconnected
----so , anyone can help ? should I try partitioning again or what? please help me

Help to Unbrick Honor 8

Hi,
I need your help as i can't get my Honor 8 (FRD-L09) unbricked:
1) It worked fine with firmware FRD-L09432B389 (except Bluetooth that won't be activated)
2) I flashed it with Lineage 14.1 using this website:
http://www.cyanogenmods.org/forums/topic/lineage-os-14-1-honor-8-nougat-7-1-rom/
3) It worked well but I got a strange message at bootup: To start Android please enter your password. This is probably due to encryption of prior partition. I made a format Data and wipe Data partition but it didn't helped.
No i still have access to TWRP but i'm unable to flash with any rom:
1) 3-Button force update mode doesn't work (it doesn't go the the update mode, even though dload/update.zip is existing on SD Card)
2) When i Try Unbrick mode from Huawei Multi-Tool i get this error message:
FAILED (remote: error partition error)
FAILED (remote: sparse flash write failure)
I confirm my bootloader is unlocked!
Thanks for your help!
Are you sure that you tried to install the exact dload file of your phone's region?
Bro just try the above post it works 100% .
Hi,
I'm trying to flash through adb sideload. I activated the ADB Sideload in TWRP As well. The transfer worked correctly.
In attachment the log of flash.
I tried to flash these stock roms:
FRD-L09C432B381_update.zip (1,3Gb)
FRD-L09C432B381_update_data_full_hw_eu.zip (1,1Gb)
My Honor 8 is from Europe, meaning these flash should be correct.
In the log i noticed these messages:
failed to mount /data: Device or resource busy
unmount of /system failed: no such volume
unmount of /cust failed: no such volume.
What do you think?
Thanks!
Yes it took approximately 50 seconds each.
For HW EU i got this message: Total xfer: 1,07x
For Update : Total xfer: 1,00x
No it is stuck at blue screen with Honor
When i'm in TWRP, I go to Wipe and Advanced Wipe:
- Dalvik / Art Cache: Invalid Partition Selection (when i click Repair of Change File System)
- Cache: ext4 - 247Mb (0Mb used)
- Data: f2fs - 24662Mb (0Mb used)
- Internal Storage: Invalid Partition Selection
- System: ext4 - 1891Mb (1781Mb used)
- Vendor: ext4 - 579Mb (481Mb used)
- Micro SD Card: vfat 59624Mb (6081Mb used)
Is it normal Internal Storage shows Invalid Partition Selection ?
What should i do after flashing both zip files (with adb sideload) ? Go to eRecovery and connect to Wifi?
Thanks,

I must after flash boot to stock eRecovery and here do factory reset, u have this choice in?
edit:no isn't normal Invalid partion Selection
Click to expand...
Click to collapse
After flashing both zip files the welcome screen is stuck at blue screen with Honor Logo.
From this i went back to TWRP to Flash with Lineage 14.1:
- I firstly got a screen that says encryption is unsuccessful and i need to click to reset phone
- I got a second screen that looks to Recovery Screen and that Reset phones (takes 1-2minutes-
- I have a third screen saying: To start Android, enter your password.
I don't have that password since it is converted from fingerprint i assume.
Can you please details how to do this:
I must after flash boot to stock eRecovery and here do factory reset, u have this choice in?
Thanks!
Phone unbricked??
No Phone still not unbricked.
What i'm trying to do know is:
- Install TWRP 3.1.1.1 by OpenKirinProject on eRecovery partitition (Should i try Recovery Partition ?)
- Install FRD-L09C432B381_update_data_full_hw_eu.zip file
- Install FRD-L09C432B381_update.zip file
- Wipe Cache/Dalvik
-In TWPR, click Reboot - Recovery
- In Recovery, choose wipe data/factory reset + wipe cache partition.
- Reboot fingers crossed
But i still have significant issues:
Failed to mount /cust (Invalid Argument)
Failed to mount /vendor (Invalid Argument)
Failed to mount /product (Invalid Argument)
Any additional help, please do not hesitate!
In my opinion all the issues i have is because partitions that are corrupted i think. Not sure if they are recovered only by installing full flash zip file.
Thanks for the help!

Yes but it's not as easy as that for different reasons:
1) First of all thanks for your help and for your post (that explains how to unbrick) but as everyone has is own understanding and knowledge/experience level in these topics, your post lacks precise steps. Example: When you say "Flash firmware for your model" should be: Click install, select your firmware in ZIP format and click Install image. For your level this seems probably obvious but it's not for everyone.
2) Even though, it is not always working. Right now i bricked my phone again by trying to install Lineage 14.1. I just recovered it but it is again multiple steps in TWRP, sometimes clicking there and there, and it works sometimes with chance. I have the feeling that we still don't know 100% sure what to do in which case to have 100% success rate.
Now i have my phone fully working in B389, Bluetooth also.
Does anyone know how to install Lineage 14.1 ? Here is the link for Honor 8:
http://www.cyanogenmods.org/forums/topic/lineage-os-14-1-honor-8-nougat-7-1-rom/
Because they explain:
Wipe data factory reset, Cache partition, Dalvik Cache and Format the System partition.
Again that's not precise:
1) Wipe Data Factory Reset ?? Does that mean:
a) Click Wipe & Swipe to Factory Reset
b) Click Wipe - Click Advanced wipe - Select Data & Swipe to Wipe
2) Cache Partition & Dalvik Cache means : Click Wipe - Click Advanced Wipe - Select Dalvik Cache + Cache & Swipe to Wipe
3) Format the system Partition : Click Wipe, Click Advanced Wipe, Select System, Swipe to Wipe ??
Because i just tried to do it (according to my understanding) and i got bootloop and access to TWRP only.
Thanks for your help.
Hi,
Yes i think you should indeed (if possible of course ). For instance, what was new for me was also the fact 2 flash images were required, one called "update" and one called "region".

Can't boot Android or recovery mode

I have a Samsung Galaxy Note 10.1 GT-N8010. One day it suddenly stopped booting Android and wouldn't pass the first screen (it didn't even reach the one with only the Samsung logo, only the one that says "Samsung GALAXY Note 10.1"). I booted into recovery mode and tried to factory reset, but I got this error: "E:failed to mount /efs (invalid argument)." So I followed this guide: https://forum.xda-developers.com/t/how-to-fix-e-failed-to-mount-efs-invalid-argument.2858056/
Here is where the problem begins. When I rooted to remove the factory mode (just following the guide), I did it using CF-Auto Root. But then my tablet stopped booting to Android (again, not passing the first screen), and when I try to boot into recovery mode, the CF-Auto Root screen boots instead (even after flashing stock firmware and TWRP). On this screen, it says the following:
CF-Auto-Root
Copyright (C) 2011-2016 Chainfire
Detecting devices . . .
- Recovery: /dev/block/mmcblk0p6
- System: /dev/block/mmcblk0p9

Preparing cache . . .
Mounting . . .
- System
- Cache
Rooting (SuperSU) . . .
Restoring stock recovery . . .
Cleaning up . . .
Rebooting in 10 seconds . . .
Then nothing happens. It still doesn't boot into Android, and if I try to access recovery mode, I get to the same CF-Auto Root screen. I can only access Download Mode, but I don't know what to flash to solve the problem. As I said, I tried flashing the stock firmware and TWRP (when I did that, Odin said PASS!).
I have been using Odin 3.10 and flashing this firmware https://sfirmware.com/es/samsung-gt-n8010/ (ARO). I also tried with a firmware downloaded through Frija (probably the same one).
I think that's everything. If I missed any information, please let me know.
Any help is welcome!
Thanks,
Whilz.
Good afternoon. I cannot guarantee that this will help you, as I have not encountered this problem and have not used these instructions. But maybe this will help you.
I found these instructions on the russian forum of the platform our devices are built on (n80**, i9300, etc.)
I will give the translation in this post and links to the original posts.
Spoiler: E:failed to mount /efs (Invalid argument) and how to deal with it!
Original post: https://4pda.to/forum/index.php?showtopic=514244&st=0#entry26179020
According to the instructions, you need to flash I9300_Repair_efs.tar.zip efs image via Odin3. IMEI and S/N will be lost, so you will have to think about restoring it.
Spoiler: Error "E: unable to mount /efs (Invalid argument)" or "failed to mount /efs..."
Original: https://4pda.to/forum/index.php?showtopic=514244&st=0#entry24433995
Attention! This method will not raise IMEI and S / N without efs backup. If you do not have it, then you can only download your phone, but there will be no network.
Tested on SGS III​
1. If you currently do not have root rights, then download them from the link from the topic header, the version for installation via Odin, install.
2. Download Custom recovery. Also versions for Odin (.tar.md5), install.
3. Download AROMA Filemanager
4. Install the File Manager through the recovery as a normal update.
5. Run the built-in terminal File Manager (press menu / select "open console" or "terminal" from the list).
6. We write commands (after each enter - input):
mke2fs /dev/block/mmcblk0p3
mount -w -t ext4 /dev/block/mmcblk0p3 /efs
reboot
The commands are taken here - http://forum.xda-developers.com/showthread.php?t=1896470
7. Reboot into the system (reboot system now).
8. We read the instructions for restoring efs (who did what) and restore.
If during loading we see a translucent pop-up window with yellow inscriptions on the desktop
then we decide like this - Club of Samsung Galaxy S III lovers (Post # 16738476)

There's quite a lot of information here that I'm not moving here. Perhaps you can learn something for yourself by translating the page into the right language.
