I have a Z5C(E5803) that was originally able to unlock the bootloader and let me flash ROMs, specifically the Cyanogen ROM that CTXz has been working on. I ran out of power and got stuck in some kind of nasty bootloop yesterday that prompted me to re-flash boot.img and TWRP.
After I did these things I left it charging for a few hours and it was able to boot into TWRP where I then restored it to a backup of the basic Xperia pre-loaded ROM.
This all worked fine, thought I could boot into TWRP and just flash the Cyanogen zip again. I can get into TWRP just fine but I attempt to flash Cyanogen I get an "ERROR 7"
I have since done several wipes, gotten into the bootloader settings by entering that code in the dialer and have seen that bootloader unlock = no. I distinctly remember bootloder unlocking being allowed the first time I installed CM on my device, what could have caused this?
I was able to use it with fastboot anyway and install CM13 again, maybe this was a bug?
When I tried using oem unlock command with fastboot it said my device was already rooted even though I had just restored from a backup, and then I just proceeded normally from there.
use CM13 official Recovery to FLASH CM13.
also i don't think so twrp3.0.2 is out there for z5c. are you using any other variants Twrp? (YUGA ? )
Lets start off with telling you i am a newbie and was just following tutorials without really knowing what i was doing.
That said, i tried to install a custom ROM but got an error (7) in TWRP. Decided to reflash my old rom and update TWRP using the official TWRP app.
So i did that but when i wanted to boot into recovery it was stuck on the oneplus screen. I went into fastboot and typed fastboot oem unlock because i thought i could flash TWRP that way if the bootloader was unlocked.
When i tried to restart it gave me nothing but the oneplus screen, even the bootloader wont start. I shut it off completely and now it doesn't give me anything at all - just black.
Can someone help me out?
EDIT:
Issue resolved using THIS. Tyvm
Hi friends,
So here's a thing:
I was trying to update my Nexus 9 to the latest Slimrom build , and I used Chainfire's flashfire app. It didn't work and sent the tablet in a boot loop. But it also wiped my recovery so I couldn't even select my recovery.
So no issues, I used the Wugfresh nexus toolkit to flash it back to stock and unroot. Bootloader is still unlocked, so I just root it again and go ahead and try to install the update using Wugfresh. It works, but says the vendor.img is wrong. So I downloaded the correct vendor.img and tried to flash it, but of course because the tablet is encrypted TWRP asked for a password. I hit cancel and tried to continue, but Wugfresh just hung at that step.
So I tried to manually flash the ROM, but now it gives me a vendor.img error and will not flash anything. Trying to flash anything sends the device in a bootloop.
TLDR; I can restore to stock and root, and also access the bootloader and recovery (TWRP) but can't flash anything without sending the device in a bootloop.
I've currently restored the tablet to stock via wugfresh's tool and rooted. So I'm back at the beginning, except with this vendor.img issue when I'm trying to flash a ROM.
Anyone have any ideas?
Hi all people,
first of all, I want excuse me for not my perfect English.
I have Honor 9 from few days. And I think to have bricked it.
I have unlocked bootloader correctly.
I have flashed recovery this TWRP recovery with the intention to proceed to root with Magisk or SuperSu. I accidentally and unconsiuosly do factory reset then the phone goes bootloop. (it power off and power on continuously) with the alert "your device has been unlocked and..etc".
Yesterday, reading this thread, I flashed, from fastboot console, boot, recovery and system, the phone resets two/three times then goes to eRecovery where I do a factory reset.
After a factory reset the phone works correctly and seems successfully unbricked. So I re-flash TWRP recovery.
But this morning, during the attempt to install from TWRP one between Magisk or SuperSu (I don't succeed to do it beacuse the phone was crypted and I don't see zip files from TWRP). I have reset the phone but goes bootloop again.
I tried to re-flash boot, recovery, system and cust more (that I don't have flashed yesterday). Now the phone goes eRecovery and ask me to connect to download latest version and recovery, but don't ask me to do a factory reset.
Now I don't know what I can do.
How I can solve this situation? I want only unlock bootloader (done!), install TWRP and have root permission. Now I don't think to change rom.
Something similar happened to me. It seems like the TWRP provided has some issue..... After installing TWRP I had a bootloop problem. I have resolved installing Magisk. It seems that Magisk patchs something. If you can access TWRP try to install Magisk (put the zip file on external sd). In other words: copy magisk zip on sd card - during the bootloop you have the chance to power off phone - Power off - Power on in recovery mode. If you have TWRP correctly installed Honor should go in recovery using TWRP . Install Magisk and see what happens...

I have tried to flash TWRP recovery again to do install Magisk from sd card. I have done it but the phone doesn't work fine.
So I have put rommco05 TWRP Backup into sd card then restored it from TWRP restore (boot and vendor img). Now the phone seems have bootloader locked, in fact I don't have bootloader warning at the power on. Now in fastboot mode the phone says me that I have Phone locked and FRP unlocked.
How can I exit from this situation?
Try this

I have unlocked bootloader again and do a factory reset from TWRP recovery, now the phone seems works correctly!!!:good:
Now I should try to root the phone with Magisk or SuperSu, right?
I have a question about TWRP. From TWRP's file manager I don't see the files that I put in the internal memory. It's because I have used finger print to lock the phone that encryptes files?

This is to re-brand the phone from Chinese to EU version...I don't think is my case.
Rommco05 said:
Take a backup before make root. You don't see files because is some issue with decryption in TWRP. I achieved root with Magisk but I don't remember exactly steps

I think it's too late
Anyway I can re-flash all thing from begin.
Then I can't use TWRP with the phone encrypted ( PIN, password, fingerprint, etc...) ?

After I have installed Magisk (v14.0) now I have problem with google play services which don't download and do updates apps.
If I do a factory reset again I can solve it?
Update:
After I done a factory reset from TWRP recovery
and formatting data partition the phone seems working perfectly (I don't know why, but before format data the phone says me that I have only 150mb of memory space)
I say "seems" because there's something getting me in trouble, for example, I don't have anymore ringtones in the settings menu.
And I don't know if I have lost something else.
Exists a possibilty to restore all contents of the phone?
You could try this and flash your phone back to stock. But then you would need to unlock your bootloader and install TWRP again. Another way would be to unpack an image of your ROM and flash system and other parts via fastboot. Of course this could be risky and you could brick the device.

If I understand it well...
I have 2 options:
1) Rebrand the phone and flashin, then at end I have back the phone stock.
2) Unpack the image of ROM (what it means?) and flash system and other parts via fastboot. (Which are those parts? How?) But this procedure is more hazardous then rebrand procedure?
I have understand right?
1. Yes, correct. I would recommend that. Everything is explained in the thread I linked. Of course everything you do could potentially harm your phone, but you should know that already.
2. Get an update.app file for your specific phone model (there are threads already here, just search a bit, or use Firmware Finder), open it with the Huawei Update Extractor and extract the parts you want to flash (like system or recovery). Then flash them via fastboot. I tried this because I was in a situation like yours, but it didn't work for me. But in theory it could, because you would replace the faulty parts of your firmware.

Hi, I don't say it because I have replaced the phone with another same.
Now I'm starting to unlock bootloader, installing recovery TWRP and rooting the phone.
I hope to avoid bootloop this time.
Goodmorning everyone!
Yesterday I have:
- Unlocked bootloader correctly!
- Installed TWRP correctly!
- Make a TWRP Backup of all partitions of the device, except data partition because TWRP gives me an error during backup attempt.
- Then I start the device.
- After start the device I go to recovery TWRP to install Magisk, but the phone goes bootloop.
After reboot 2-3 times on the screen appears for a few moments a message of eRecovery that have restored something but I don't know. Then the device shows me the eRecovery that asks me to make a factory reset.
At this point I shutdown the device, go in TWRP to flash Magisk unistaller and the device goes out bootloop and works fine but without root.
How I can solve this problem and install Magisk and have root finally?
Some question:
-When I flashed TWRP (via fastboot) and I configurate it, example language, hours, etc... TWRP don't save the settings, in fact when I go in TWRP again I do remake the settings. Why?
-Then I go in sdcard I don't navigate files, I see folders with casual characters. This is an effect of encryption of the device?

Answers to all your concerns go here mate---> TWRP doesn't decrypt data. Done.
Hence: weird folders in there, nowhere to store its settings prefs, about Magisk it's another story, if you want root go SuperSU latest beta.
Regards.
a basically did what that guy did, got root installed via TWRP but my google apps are all busted.
I tried flashing the update_data_full_public.zip and update_full_hw_usa.zip I found using the russian device lookup link switching trick but I the HW errored when I tried to flash it in TWRP and my play store still broken.
So i had a hickup with updating magisk to v20.3.
The result was that after a reboot the device got stuck in fastboot mode.
I went to TWRP 3.3.0 recovery and backed up all offered partitions before then attempting to re-flash magisk.
Didn't work out.
Then i heard that if you extract the boot.img from the stock firmware and flash it with fastboot you can get back to a working state where you can install Magisk again.
So i thought.
Now after booting i am greeted by the miui first install wizard and the whole set of apps seems to be gone as well as my settings.
IIRC i only removed the dalvik cache which shouldn't affect this state.
Where in the procedure is the mistake and can i get the old pre-broken update state back? I am afraid something has been lost in the process

Just install the latest stock rom then install recovery and restore all the backed up partitions.
Now install magisk and reboot.
If that doesn't work (u get into fastboot again) then just flash the boot.img file via fastboot and then reboot.
if i restore the backed up partitions and install magisk over it i get back to the non-booting , stuck in fastboot version. So something is wrong in the state of denmark.

I looked at the /data backup from twrp and it is only 3mb, unless stuff got moved to /system or so, it seems to be gone forever.
Hell , i wil never update magisk again.

Don't install magisk with the rom, just restore the data, flash the stock boot.img file and then reboot.
After boot uninstall the magisk manager app and reboot to recovery and then flash magisk again.
