I was trying to install LineageOS 16.0 on my P20 Lite. I was following the official tutorial: https://wiki.lineageos.org/devices/anne/install
When I was trying to format the data partition, twrp never finished. I googled it and found the following thread: https://forum.xda-developers.com/oneplus-3t/help/stuck-formatting-twrp-t3586406
I rebooted my device to see if i could format it in ext4 (it was using f2fs by default)
But after rebooting, i couldn't get into the recovery ( stuck at twrp boot screen ).
I already tryied:
1) Reflash the twrp recovery
2) Flash the default recovery ( stuck at 'Your device is booting now' )
3) Boot into eRecovery to restore the device ( stuck at 'Your device is booting now' )
4) Format data partition from fastboot ( 'Command not allowed' )
4) Flash default system image ( Because it was on the thread i found )
5) Flash kernel image ( Don't know if this would change anything )
The only thing I can really do is boot into Fastboot.
Is there any way to restore my device?
Hope someone can help me

Have you changed the 'data' format to ext4?

I wasn't able to because fastboot wasn't allowed to and I can't boot into my recovery to do it.

it's all right, normally it is on each P20 lite device f2fs (including Custom ROMs). Have you tried Stock recovery from fastboot? ( You TWRP is installed over Recovery or over eRecovery?)

Yep I flashed the stock recovery multiple times but it's also stuck at the boot screen ( 'Your device is booting now'). I've waited for ~15 Minutes, but nothing happens.
Okay,
I was able to recover my phone by booting into fastboot and erasing the userdata partition. Then the info '(bootloader) success to erase cryypt info in oeminfo' popped, what surprised me. After that I was able to boot into eRecovery and recovery my phone!

First of, I'm running Cyanogenmod 12.1 on my Z2.
On the install it vanished my TWRP Recovery, so I decided to reflash it using their app - this was unsucessfull. I thought I would flash it the next day using adb, so I didn't mind.
However in the next hours I needed to reboot the phone - resulting in the Sony logo and nothing more. So I bootet into the CM recovery and tried to reflash the CyanDelta zip - this failed and resulted in "footer is wrong - signature verification failed - Installation aborted". The next thing I tried was flashing a zip by adb recovery sideload - this failed as well and resulted in "protocol fault (no status)".
This was when I tried to boot into the bootloader using the recovery menu entry. The screen got black, the LED lighted up blue and nothing happened forever. The same thing occours when I try to boot into the bootloader by hardware keys (hold VolUp and insert MicroUSB cable).
So, in short:
I can't boot android
I can't install zips by CM recovery
I can't boot into the bootloader [EDIT: I can.]
I can't install nandroid backups since the CM recovery doesn't offer that
Any idea?
If the phone's LED lights up blue it means that you are in fastboot mode (AKA the bootloader) . It is normal for the screen to be black. I suggest that you download a stock FTF and flash it using the windows flashtool application. Your phone is fine. Good luck.

Ah, I feel dumb now. I might be damaged from the informational Nexus bootloader.
So, I tried to flash a new recovery - fastboot flash twrp-2.8.6.0-sirius.img - which succeded, but it still boots the CM Recovery. Buh.
Seems like something is overriding the recovery on boot. So lets erase everything:
Code:
fastboot erase system
fastboot erase userdata
fastboot erase recovery
fastboot flash twrp-2.8.6.0-sirius.img
Aaaand - still CM Recovery.
I also tried to flash a stock image as you suggested, however:
Code:
fastboot flash system system.sin
sending 'system' (1800183 KB)...
FAILED (remote: data too large)
finished. total time: 0.002s
No worries, I came from a nexus 4 and it confused me as well at first. Try exacting http://forum.xda-developers.com/xperia-z2/development/kernel-m5-kernel-t2858912 and flashing the boot image via fastboot. That should give you a working recovery.
As I said, flashing a recovery by fastboot results in the CM Recovery.
I just tried to wipe my device using the CM Recovery, it told me it was unable to mount /data - my guess? The filesystem is ****ed up.
EDIT: I got it. Seems like TWRP needs some custom stuff to work (which is provided by CM). Flashing philz worked fine and allowed me to sideload a proper ROM. Everything fine now
Recently bricked my honor 5x used fast boot to get it out of boot loop. (Because I tried to its update my phone with twrp)now when I try to re flash twrp it gets replaced by the stock recovery Everytime . Please help!
Samething happend to me... cannot flash twrp because when i restart phone after flashing twrp, it gets replaced by stock recovery.
What i do now is to boot to twrp instead of flashing using this command:
Code:
fastboot boot twrp-3.0.0-0-kiwi.img
Hopefully there is a solution for this flashing problem.

you can't just reboot after flashing recovery ...you have to boot directly to twrp after the flash with power + volume up (Skip the fastboot reboot step)
the simple way is to copy kiwi_twrp_3-21_recovery.img to your sdcard
fastboot boot kiwi_twrp_3-21_recovery.img
now in twrp choose install / image / then choose kiwi_twrp_3-21_recovery.img
next choose reboot / recovery
you now have kiwi_twrp_3-21_recovery.img
from then on adb reboot recovery from android
or power + volume up will enter TWRP

why are you using adb ?
did you read the instructions i posted
I have the stock recovery.
I cant get into twrp.
I tried to flash then go straight to twrp which gets replaced by stock bootloader
Idk it gets replaced everytime
Okay the adb thing stopped I got into twrp by doing the fastboot thing but when i boot into recovery it goes to the stock recovery.

I really don't know why you don't seem to get it
it's this simple
you fastboot boot kiwi_twrp_3-21_recovery.img
now while in TWRP copy kiwi_twrp_3-21_recovery.img to the phone
Also copy SuperSU-v2.64.zip (or newer) to the phone
after the files are copied choose Install / Image / kiwi_twrp_3-21_recovery.img
next choose install / SuperSU.zip
next choose Reboot / Recovery
you now have TWRP recovery and you can enter it by using power + volume up
or from an app on the phone (I use Quickboot) or from a pc with adb reboot recovery
I have the same problem, i tried with your method but the system continue to replace bootloader, impossible to keep twrp on recovery
Edit : I try to install Root Checker, it detect my phone is root but impossible to access to TWRP, very strange

Tried this on my KIW-L21, as this is the only way I did not try it yet...
Did not work, unfortunately, I assume the OP could have the same problem as I already posted in the TWRP thread:
http://forum.xda-developers.com/showpost.php?p=66678377&postcount=509
(It is a shame people spam this thread with unlocking problems, though)
EarlyMon mentioned something about dual recovery partitions here: http://forum.xda-developers.com/showpost.php?p=66838009&postcount=529
So regardless how many times I flash TWRP it wont stick until the next reboot to recovery, as it gets replaced by the stock one all the time.
I am thankful for every news on that topic and I would happily help(to the extent I am able to) getting TWRP back onto our phones :good:
P.S.: I am not quite sure if the OP has another problem in flashing the recovery, though.

So you are booting TWRP
Installing / TWRP.Img in TWRP and Reboot recovery and your not booting to TWRP ?
Just my two cents into this thread: apparently (from my personal experience, and EarlyMon seems to back this up) the Honor 5X for whatever reason allows the installation of TWRP but still keeps Huawei's stock recovery in place, unlike most phones. What's more, it randomly (yeah, guessing it's not random obviously, but I don't have the slightest clue what the pattern might be) decides to boot into stock recovery while I use the same hardware keys that have continuously booted me into TWRP up until that point. This behavior led me to believe I had bricked my phone for a day, lol (I made a recent post about it on this forum, in case anyone cares).
Bottom line: if you can't boot into TWRP even though you made sure to install it correctly, try changing the key combo. Vol down + Power not working for you? Try Vol Up. Neither work? Try Vol Up + Down + Power. Spice it out and it might solve your problems.

That is correct:

The last approach was done with the one from the first post of the TWRP thread here on XDA(https://goo.gl/53xai9) "kiwi_twrp_3-21_recovery.img"
I also tried the TWRP images from https://twrp.me/devices/huaweihonor5x.html but always the same result.
I can try with a specific image, just give me a link and I'll try to flash it. :fingers-crossed:
Hey everyone.
All the links for downloading 10F appear to be broken. I need to downgrade from 10V to 10F so I can root, but can't file the firmware anywhere.
Anyone any ideas where I can find a working link?

Why would you need to downgrade to V10f for root ?
Im running V10v and have no problem at all.
flash TWRP in fastboot (fastboot flash recovery twrp.img), then boot that image (fastboot boot twrp.img)
Now youre in TWRP, enable modifications, reboot into recovery again (so you boot the one thats actually flashed)
then flash lg-rctd, no-verity-opt-encrypt-6.0, completly wipe data (factory reset, includes internal memory to get rid of encryption, optional) and flash Magisk
Now you have a rooted stock rom. Optionally with disabled encrpytion (only if you completly wiped /data ), so you can actually take a backup of that partition too and twrp is able to mount it
Some ppl had problems with V10v installing TWRP like me. Tried 1000 times to no avail, downgraded to V10f and TWRP worked the very first time w/o any problems on the lower FW vers.

Like the guy said below, I've tried a few times and never been able to get TWRP to stick.

Thats what the fastboot boot twrp.img and then reboot recovery (inside that twrp) commands are for
To actually make it stick and not get it overriden again.
Edit: had todo that twice actually, because i ****ed up the system one time, and went back to completly stock to find out what i did wrong (result, a magisk module was causing some error)

Hi all,
I unlocked my phone and I installed LineageOS 14 (thanks to TWRP).
I tried to update Lineage (i had a notification), but when I rebooted, the stock recovery was launched... not TWRP.
Of course, i've flash TWRP several times... but at each reboot, the stock recovery come back..
From my PC, no problem :
- adb reboot bootloader : OK
fastboot flash recovery twrp-3.2.3-0-kiwi.img OK
fastboot boot twrp-3.2.3-0-kiwi.img OK
From the phone, with the correct combo key (Volume Up + Power), TWRP wasn't launched...
Could you help me ?
Thanks !
What happens when you boot to recovery via adb?
Adb reboot recovery
Thanks for your answer !
Screen "EMUI" appears
with
- Reboot system now
- Wipe date/ factory reset
- Wipe cache partition

Is your usb connected while you boot to recovery.? If yes remove and boot once they see of that makes a difference
- adb reboot recovery
- Phone shutdown
- I remove the USB cable
Phone restart

Are you flashing the correct version of twrp. Whats your LOS version and which twrp you are using. May be the one you flashed is not compatible
I think You have skipped one, but important point of flashing twrp. There is a point what to do to prevent of returning into stock recovery after first twrp flash. Please read carefully all steps from howto and follow them in right order.
Good luck, Bro ??
Current State:
TWRP Installed, no OS, no system partition, instead a super partition.
I also flashed an orange_state_disabler which seems to have worked just fine.
ADB Sideload:

I converted the lineageos img file I have to a flashable zip using the tool from here:

but when I try to flash that zip file tho it returns this:

Checking for Digest file...

A Custom ROM like LineageOS can only get installed via TWRP, not by any other means: in no case by "adb sideload".

Your posted error messsage suggests the zip install has failed. So no change to device should have happened.
Current twrp cannot flash system.img
Only super.img(combined system.img, vendor.img, and product.img)
The systemswapper you refered to is from a qualcom device thread, and uses some *qti* device binaries that are not in your recovery. It is unlikely to have worked. (I might be wrong about the *qti* binary being only a qualcom device tool)
These new devices with dynamic partition have 2 fastboot modes.
The bootloader mode (adb reboot bootloader)
This is used for unlocking bootloader, flashing standard partitions
There is fastbootd mode (adb reboot fastboot)
This mode is only available if stock recovery is installed.
It also requires r30 or higher fastboot binary file on PC.
From fastbootd you can flash the sub partitions on super.img
There is alot of changes that take place with this new partition setup.
As for your phone no longer booting into original system, and bootlooping to recovery, I suggest first try boot to bootloader, and flash stock recovery, see if this stopps the bootlooping.
If not then use sp flash tool and flash full stock room and start fresh

Fastbootd is part of stock recovery, it will look different than what you may be used to as being fastboot mode.
You should see options on screen to select just like stock recovery has.
One for boot to bootloader
One for boot to recovery.
When you confirm you are in fastbootd
You just use
Code:
fastboot flash system /some-directory-on -pc/gsi-system.img
You should see messages on screen
Resizing system
Sending sparce system chunck. 1 of x
Writing system chunck 1 of x
There could be more descriptive guide on flashing gsi on dyniamic partitions if your Search google, (xda).
But it is hard to guide you to fixing device, when I'm not sure how you got stuck. I mean the description you have said should not have made you loose system partition or fail to boot, so I said it before and will suggest it again. If you have a non booting device , the FIRST thing you should do is flash it with sp flash tool and full factory rom, before messing around with other stuff before you get into worse condition

Ok, I am back to a fully working device again, where I got stuck was that I do not have a system partition, thus I can't flash it. Whenever I try to flash it using fastboot flash system or anything else, it just says that I do not have a system partition
Where I am right now:
I am back to a fully working device after downloading the stock ROM from my manufacturer and plugging that into SP Flash tool
After that I researched and figured out that the super partition I have basically acts like a container for
system.img, boot.img and vendor.img
which explains while simply flashing LineageOS.img to my super partition (
Code:
fastboot flash system Lineage.img
) resulted in
my device not booting anymore.
I found a tool which can unpack those super.img into system, boot and vendor
(using this youtube video: https://youtu.be/J5cQdzivtXk)
I used that to unpack the super.img which I got from my stock ROM and
now I have system.raw, boot.raw and vendor.raw, I do not know what kind of file these are but my plan is to replace system.whatever with the lineageos.img and then repack it into super.img which I can then use to flash the super partition on my phone

@MoonPadUSer
Code:
fastboot flash system Lineage.img
must have failed.
Reason: This command tries to write a complete Lineage OS ( what itself contains a partition named /system, too ) into phone's Android's current /system partition - what only is 1 partition of multiple ones that exist.
Note: You can't flash a Custom ROM by means of Fastboot.

Actually... I don't really care about the version all that much, whatever works, just didn't know if 18x is supported
Downside to Lineage GSI is for Umidigi you can't flash gapps. So unless someone adds it to the gsi for you it's best to use something else.
I went with this
https://forum.xda-developers.com/pr...velopment/aosp-10-0-quack-phh-treble-t3992559
You have to get the AB version with GAPPS if you want them
Comes pre rooted as well and gave my phone a huge speed boost
Flash the stock ROM
Unlock bootloader
fastboot flashing unlock
(unnecessary if already unlocked)
fastboot flashing unlock_critical
enter fastboot
fastboot reboot (to enter fastbootd)
fastboot erase system
(optional but I had to do this myself)
fastboot delete-logical-partition product - deletes the product partition, allowing a larger system partition
fastboot flash system (gsi file)
And you're good
Don't try to install magisk because it causes a bootloop. Even when installing it through the app. Once the boot image is patched you're in a bootloop until you reflash the stock boot
Made a generic ish Umidigi flashing tutorial because it's the same in all of them I've had so far
