Yesterday I tried to flash a a new rom on my Xperia Z2 (unlocked bootloader).
From TWRP I did an advanced wipe and selected basically everything except my mircoSD (because it has the new files).
After a long time of waiting I tried to flash the ZIP file and it gave me an error. I thought this had to do with the wipe so I decided to reboot my phone.
As you can imagine, it got stuck on the Sony logo (because system would be empty).
From this moment I couldn't do anything with my phone, except from the tool Emma.
I now have some clean installation of Sony their Android 6.0.1 for the Z2 (23.5.A.0.570) but Im unable to flash TWRP through fastboot.
The command adb devices shows my phone, fastboot devices gives an empty response.
When I restart to the bootloader from adb and try to flash TWRP I get the message "< waiting for device >".
I tried on three different PCs including a clean install of Windows with all kind of different drivers, yet I cant get fastboot to work.
Am I stuck with this unrooted version of Android now or do you guys have any suggestions for me?
Thanks in advance!

As I said I've tried all kind of different drivers (Android tools, Sony drivers and flahstool drivers). So for me it's hard to tell what I'm doing wrong.
My computer notices the phone (if I hold volume up and attach the charger), it just doesn't show up under fastboot devices.

Okay, apparently it was because of the driver signature stuff in Windows 10.. The fastboot command now works fine!
Next problem occurred though, flashed the newest TWRP recovery but as soon as I enter "adb reboot recovery" my phone just normally boots again..
Why do things never work out the right way for me as they are intended..

Manually boot into recovery by booting up your device normally and when you see a violet LED, press vol+.
[At first, I have a Huawei p9 Lite] I recently was stuck in reboot mode, my phone would not boot up anymore and just keep rebooting so I went into twrp and did a factory reset without having a backup because I did not have any important files on my mobile. I then still could not boot up so I accidently wiped the whole cache and deleted my OS, so now my phone won't even boot anymore and it's stuck in the "Your device has been unlocked and can't be trusted" screen. How do I make my phone work again? I don't know anything about how to download stuff on my phone when I only have twrp left so I can install it with twrp and then boot again.
EDIT adb push doesn't work either and I can't wipe because it always gives me a red error line in twrp "Failed to mount '/cache' (opperation not supported on transport endpoint)

OK so, whenever I try to adb sideload a rom from my pc to my mobile and I go to adb sideload in twrp and swipe it disconnects from my pc and I hear a de de de sounds
That device has an sdcard slot, so just move your desired rom over to that and flash it.
Also, may I ask what rom you had? Lineage os is available for your device (not sure, but if someone compiled twrp, sources are available which means that you can compile it for your device)
Good evening XDA Developers Forum,
I am trying to figure out how to install LineageOS 14.1 on a Huawei Honor 5X without getting into too much hassle. (If you are not interested in my chit-chat, I recommend reading only the bold text.)
Why do I need help? I tried to install LineageOS 14.1 right after buying a fresh new Honor 5X following the instructions at the LineageOS-Wiki*, but things didn't went as expected. After 5 days of macgyvering the (suspectedly) bricked phone I managed to get it running again, but not yet with LinageOS. So I wanted to share my experiences to help others having similar problems and I want to avoid too much stress with the next steps. (* I wanted to link to the Wiki, but due to being a new user, I am not allowed to. You may follow the kiwi-Install-Instructions in the LineageOS-Wiki.)
Kind of disclaimer: I've modified my mobile devices a few times in the past years. I rooted and installed CyanogenMod 12.1 and later an XDA-Dev-built Android 7.1.2 on a Nexus 7 3G 2012. I rooted and installed CyanogenMod 12.1 and later 13.0 on a Nexus 5. I stumbled over some problems, but after some trial and error everything worked. Therefore I thought I was a bit experienced and could easily do that stuff with a phone that is listed as "supported"... I didn't ignore mandatory steps of the LineageOS Wiki. I did RTFM and read this forum. I often found questions being close to my problems, but sometimes I didn't understand the answer or often the answers didn't work for me. I hated to see how this forum tried to help new users that didn't reply on questions and how some new users neither followed the instructions nor posted their solution. I promise not to let the thread die before I summarize a solution. As soon as I'm allowed to, I'll link all the files I used to their source, I kept track of them all.
You may skip the history passage if you're not interested in the pre-story or if you don't want to profit of my trial and error experience. So here comes what I did until today:
Update Google USB drivers, already have adb and fastboot installed
Buy a new Huawei Honor 5X
Check its attributes: It's a KIW-L21 with a Huawei version of Android installed, version 5.1.1 and EMUI 3.1. This device is called "kiwi".
Successfully receive unlock code via Huawei
Root the phone via fastboot, until the fastboot & rescue mode screen says "OEM Unlocked, FRP Unlocked"
Flash TWRP 3.1.1.0 (kiwi) to recovery
Push lineage-14.1-20170809-nightly-kiwi-signed.zip to /sdcard on the phone
Wipe cache, system and data
Start install of the above LineageOS .zip file in TWRP
Installation getting aborted with "assert failed: kiwi.verify_trustzone(...) ==1" and ending with an "Error 7"
Learn from the forums that I should have installed "stock MM" first. "MM" seems to be Marshmallow, also known as Android 6.0
Search for images of "stock MM", end with a complete mess of gigabytes of dozens of images, differing by region (Arab/Europe/Americas/etc.), build numbers, firmware stuff, model numbers... oh crap, I don't understand a word
Extract different "stock recoverys" from multiple firmware packages, try to combine them with all kinds of firmwares
Flash stock recovery "recovery_l21_b130.img" to recovery, put SD card with /dload/UPDATE.APP (KIW-L21C432B130CUSTC432D005.dload.modaco.zip) into phone, reboot with Volume-up + power button, start factory reset, end with "data and cache format failed"
Flash stock recovery "recovery_l21_b130.img" to recovery, put SD card with /dload/UPDATE.APP (08_Huawei_KIW-L21_Firmware_C432B130CUSTC432D005_Android 5.1_EMUI 3.1_Finland.zip) into phone, reboot with Volume-up + power button, start factory reset, end with "data and cache format failed"
Flash stock recovery "RECOVERY.img" (from Extracted_L21_B130.zip) to recovery, put SD card with /dload/UPDATE.APP (08_Huawei_KIW-L21_Firmware_C432B130CUSTC432D005_Android 5.1_EMUI 3.1_Finland.zip) into phone, reboot with Volume-up + power button, start factory reset, end with "data and cache format failed"
All of the issues resulted in a boot loop
Wife getting mad because I bricked her new phone and wasted nights for it
Finally find this nice file depot of the Honor 5X in this forum but do not understand all the different headers or the structure of the list
Find out that the used firmware versions may have been too old (although I thought I should have used "stock" and therefore the oldest ones)
Try my luck with flashing L21_B130\RECOVERY.img (from Extracted_L21_B130.zip) to recovery, used "KIW-L21 C432B350 - D003" from the file depot to copy its UPDATE.APP to /dload/ at the external SD card, held both volume buttons and the power button until reboot
The Honor reboots into an autorecovery mode, installing the file from UPDATE.APP automatically and for the first time not cancelling the process
Great success!
I feel myself like I "unbricked" the phone
I am now holding a running Huawei-crippled Android 6.0.1 in my hands
My current situation is a running Huawei Honor 5X with a Huawei-branded Android 6.0.1, EMUI 4.0, build KIW-L21C432B350, custom version CUSTC432D003, fastboot & rescue mode screen saying "PHONE Unlocked". Unfortunately – you may have noticed – that is not LineageOS 14.1, which I actually wanted to install. How do I do that? Should I just follow the wiki instructions? Do I now have a "stock MM installed"? Doesn't it become uninstalled when I wipe system in TWRP before I install LineageOS?
When I try to read information of the phone via "fastboot getvar all", I just get an empty value after "all:". Why is that?
Rather than struggling over anything else when I try to follow the LineageOS wiki install guide again: What should I do or check first? I do not want to get a "kiwi.verify_trustzone" error again. How do I avoid that?
Thanks for your patience in advance!
You're on B350 and it's a good firmware to go (my phone was using it before 'conversion'). Flash twrp via fastboot, clear system/data/caches (backup your and app data first! if you want) and just flash Lineage + gapps (at once, no reboot between). You should be fine.
You are good to go
I have the problem that i cant get MM on it. I am still on b160.
I copied the dload folder for b330 on it and went to updater, menu, local update, update.app and press install
My phone reboots into twrp and nothing happens. I also cant boot into stock recovery. When i press vol up, vol down and power, my phone restarts over and over again. When i release the Buttons it just boots into android.
How do i get b300+ on it?

You can't flash stock images with twrp. You'll have to revert recovery back to stock one (extract image from b160) and then try to update.
ok that was a little bit to fast. do i need to download stock recovery and flash it via adb? because i got TWRP on it this way.

Please do not steal my thread topic. I am trying to complete a tutorial.
you literally had the same problem I have. You had TWRP on it and tried to get stock recovery back to install MM. wouldn't it be part of a tut to explain how you did that? And since you know the answer, cant you tell me?
It worked! I finally got LineageOS working. Thanks to ShadySquirrel and PalakMi for your verification of my installation!
So here is my ultimate tutorial how to install LineageOS 14.1 (= Android 7.1.2) on a brand new Huawei Honor 5X KIW-L21 that comes originally with a Huawei branded Android 5.1.1:
Step 0: Preparation
You have up to date Google USB drivers installed
adb and fastboot are working
You know how to check checksums
You checked your device: It's a KIW-L21 with a Huawei version of Android installed, version 5.1.1 and EMUI 3.1. Your device is called "kiwi".
With your detailed device information, you ordered an unlocking password from Huawei (except your phone is already rooted)
Step 1: Install Stock MM (= Marshmallow = Android 6.0)
Root the phone via fastboot until the fastboot & rescue mode screen says "OEM Unlocked, FRP Unlocked"
You can reach the fastboot & rescue mode screen by plugging your phone via USB to a PC and keep volume-down + power buttons pushed until you see the Honor logo
Download the following images and its checksums and check them to avoid corrupted files:
- Stock recovery image from Extracted_L21_B130.zip: L21_B130\RECOVERY.img
- Stock MM from this nice file depot of the Honor 5X in this forum: KIW-L21 C432B350 - D003
Flash the stock recovery to the phone with fastboot when you are at the fastboot & rescue mode screen: "fastboot flash recovery RECOVERY.img"
Copy the UPDATE.APP of the above file to /dload/ at an external SD card and put it into the phone
Hold both volume buttons and the power button until reboot
The Honor reboots into an autorecovery mode, installing the file from UPDATE.APP automatically
Wait until it's ready and be happy about your Honor 5X with Stock MM
Check if you are at this status: Huawei Honor 5X with a Huawei-branded Android 6.0.1, EMUI 4.0, build KIW-L21C432B350, custom version CUSTC432D003, fastboot & rescue mode screen saying "PHONE Unlocked"
Step 2: Install LineageOS
Download the following images and its checksums and check them to avoid corrupted files:
- TWRP 3.1.1.0 recovery image for the Honor 5X (kiwi): twrp-3.1.1-0-kiwi.img
- LinageOS 14.1 nightly build for kiwi devices: lineage-14.1-20170816-nightly-kiwi-signed.zip
- Open GApps package for ARM64 / Android 7.1 (in my case I choose "pico" to have the calendar and Google Play): open_gapps-arm64-7.1-pico-20170819.zip
Place the files where you can reach them from your adb/fastboot-console
Connect phone via USB to PC
Keep volume-down + power buttons pressed until phone restarts and shows Honor logo, release buttons; "Fastboot & Rescue Mode" screen should appear
On PC, check with "fastboot devices" if phone is connected and ready to go (should list an ID and the state "fastboot")
Flash recovery with "fastboot flash recovery twrp-3.1.1-0-kiwi.img"; should report sending and writing with two "OKAY" messages and a "finished"
Try to start recovery mode by keeping volume-up + power buttons pressed until Honor logo appears, release buttons and wait ~ 20 seconds
In my case, this started the Huawei eRecovery – you don't want that (and it's not part of the LineageOS wiki)
Navigate with the volume buttons to "Reboot" and press the power button; phone should boot normally
Once your old Android is up again, activate USB-debugging
Check if adb is connected to your PC with "adb devices"; you must allow access to the device on your phone when prompted, the device should appear with the serial number and the state "device"
Restart into the recovery mode you really want with "adb reboot recovery" and wait until TWRP boots; allow writing on its first start
Check if adb is connected to your PC with "adb devices"; the device should appear with the serial number and the state "recovery"
Push LineageOS image and Google apps to phone with "adb push lineage-14.1-20170816-nightly-kiwi-signed.zip /sdcard/" and "adb push open_gapps-arm64-7.1-pico-20170819.zip /sdcard/"; both should report transferred size and time
Do not forget to push the md5 checksums if you are paranoid like me
Backup everything to an external SD card from the Backup menu in TWRP (needed 4021 MB of space and took ¼ hour in my case)
Seriously, backup! Even though you haven't done anything with the phone yet. You have a running firmware, that's worth a lot
In TWRP, select "Wipe" and then "Advanced Wipe"
Check "Cache", "Data" and "System" and swipe to wipe
Go "Back" to return to main menu, then select "Install"
As you have backed up to an external SD card, "Select Storage" to "Internal Storage"
Navigate to "/sdcard", select lineage-14.1-20170816-nightly-kiwi-signed.zip and swipe to confirm flash; should not take more than a minute
When it's done, do not reboot but navigate back to "Install" and install Google apps by selecting open_gapps-arm64-7.1-pico-20170819.zip and swiping to flash
Once installation has finished, return to the main menu, select "Reboot", and then "System"; the Honor logo will appear shortly
LineageOS 14.1 is now being initialized
Disconnect phone from PC
Profit!
I'll provide links to the images as soon as this forum allows me to.

You are right, sorry, I was being too harsh. I'd like to post the link to the recovery image I've had success with, but I am not allowed to do so. Maybe you'll find it when you look for it and follow the instructions of my last post (Step 1). Does it work?

Hi I want the same kind of tutorial for KIW-L22 also. I tried almost every methods to flash any custom ROM. But all ended up as a failure. WhatI did was, I was in KIW-L22C675B360 version of EMUI. I unlocked the bootloader the official way, flashed twrp as proposed by TWRP site (fastboot flash recovery my-twrp.img). I booted into recovery successfully. I BackedUp all my partitions (Thank god that I did this). Then I wiped my Data, Dalvik-Cache, Cache, System, Android Secure. Then I flashed the latest Lineage OS (lineage-14.1-20170816-nightly-kiwi-signed.zip) and flashed the latest Open Gapps nano. Then I rebooted. There was no problem with the installation. Then the boot animation started loading and I was waiting to see LineageOS. :crying: :crying: But all of a sudden, the boot animation freezes and the phone starts rebooting. This was happening all the time no matter how many times the phone rebooted. I thought it might be a ROM problem and i went back to twrp by holding power up when the phone rebooted. Wipes all as before and flashed certain other ROMs like AospExtended, MIUI 8 (PatchRom), etc but neither of them booted. I don't know what to do after that and I restored my old TWRP backup and now I'm on stock EMUI KIW-L22C675B360. I would be thankful if I get a solution to solve this problem. Waiting eagerly for answers.

Good to know :highfive:
@Et tu, Brute? : mate, I followed your instructions but the device ended up in bootloop. Any help?
m on twrp 3.2.2.0
Lineage OS v14.1 (29th Jun build)
Gapps 7.1 x64 pico
I flashed TWRP to the device successfully, and proceeded to try to install Magisk 19.3 zip. It would begin to do a recovery bootloop. I fixed it using TWRP, and tried using the patched boot img from magisk manager instead. This is where things go wrong. After flashing boot.img, the phone refuses to boot, and asks me to do a factory reset. I did this twice, and the phone continued not to boot. I then tried installing the latest android Q factory image. The flash failed, and the phone stopped showing up when I do fastboot devices or adb devices. It is stuck in the bootloader telling me slot b is not bootable. I have tried different ports, but adb and fastboot are no longer responding.
Take out the battery for 10 sec or more replace, see if you can get back into recovery. Recovery should be TWRP.
You may need to uninstall and reinstall the driver on your computer. IF it is a Win computer should show up in device manager at the top under Android.
https://www.xda-developers.com/how-to-install-custom-rom-android/
or you can do a factory reset which is also a button.
I fixed it by holding down the power and vol up buttons, which allowed me to use fastboot again and fixed everything. Thanks for the help tho>
Hey community,
I have been running Poco F1 with twrp and PixelExperience for the last 2 years. Considering the past record of the OS and my experience with the OS, I decided recently to upgrade to the newer PE12 for Poco F1 (maintained by Lakshay Garg). It went smooth initially and after the last OTA update, the phone started behaving weirdly.
Long story short,
This morning the phone went into an automatic restart and is now stuck in a boot loop. It boots and reaches the "G" logo and reboots. However, the weird part is,
Code:
fastboot flash
and
Code:
fastboot boot
are not available, throwing errors. The device is visible in
Code:
adb devices
and
Code:
fastboot devices
. This problem occurs when the phone is not plugged in. Once plugged in, the phone runs fine and everything just works. TWRP is not accessible, as if it is not there anymore and the only recovery that I can reach is the pixel recovery which has no option to flash any custom recovery (newbie, so not sure if something like this should exists or not).
I've tried various threads here and wasn't able to find any solution. Let me know what commands/outputs you guys might need from the device to help me in this.
Thanks in advance. Hope this gets fixed soon.

TWRP is not accessible, as if it is not there anymore and the only recovery that I can reach is the pixel recovery which has no option to flash any custom recovery (newbie, so not sure if something like this should exists or not).
I've tried various threads here and wasn't able to find any solution. Let me know what commands/outputs you guys might need from the device to help me in this.
Thanks in advance. Hope this gets fixed soon.

Seems to be a battery problem. How old is it? You may need to replace it.
However make sure you followed the clean install method before you come on a conclusion. Also try to not use any Magisk modules.
Best Clean Install method:
Backup all your data. All your data into Internal Storage will be lost during this process.
Download latest Official TWRP Recovery, Pixel Experience build.
Create one Folder and move all the files you downloaded there.
Reboot to Fastboot Mode
Connect your device to PC and Boot into to TWRP via ADB or Minimal ADB and Fastboot:
Code:
fastboot boot <recovery_filename>.img
Example:
Code:
fastboot boot C:\Users\Retrial\Desktop\twrp-3.6.1_9-0-beryllium.img
Select Wipe > Advanced Wipe -> Select Dalvik / ART Cache, System, Data, Internal Storage, Vendor, Cache and then Swipe to Wipe.
Go back and select Wipe > Format Data > type yes
While you are in TWRP, transfer the Folder with the files you downloaded above.
Flash Pixel Experience ROM.
Flashing the ROM will replace TWRP with PE Recovery so OTA updates can be installed without problems since TWRP currently doesn't support decryption on A12 encypted ROMs - If you need in future to change ROM just fastboot boot to twrp via adb and flash img of twrp to recovery partition.
Done! Reboot to system.
Thanks, turns out that it was a battery problem after all. After battery replacement everything is working just fine. I also installed Awaken OS as Pixel Experience was removing the TWRP recovery each time I flashed it. Now as for my fastboot, initially it was not working; it was showing this error whenever I tried to flash TWRP recovery or any stock recovery:
Sending 'boot.img' (38640 KB) FAILED (Write to device failed (Cannot send after transport endpoint shutdown)) fastboot: error: Command failed
After this, the fastboot mode was diconnected and my phone was showing this Error:
Press any Key to Shut Down
It was resolved by running this bat file (as admin) :

After running this file, there was no error and I was able to flash the twrp Recovery smoothly. So thanks for all the help really appreciate it.

Did you face the problem again?
I am using PE11 since last 2 years but suddenly i started facing the same problem. When plugged in, works fine. When I unplug it, works until screen is on and when I use power button to lock or unlock, phone goes into bootloop. I opend it in twrp where it can work as long as battery lasts, that's why I am not sure if it's a battery problem or something else
