Hi,
so basically last year a friend of mine asked me to install a ROM on his phone so I successfully installed the official CyanogenMod 11 but he tried to download an OTA update which led to the phone not being able to recognise his SIM card. He wanted me to install the unofficial CyanogenMod 12.1 but I messed it up.
I don't know why but I tried to flash the boot.img (from the .zip of the ROM) with fastboot and rebooted the phone, then it got stuck on a black screen.
I somehow was able to have access with adb and rebooted into recovery but I tried installing the recovery from the official CyanogenMod 11.
Since then I can't get adb nor fastboot to recognise this phone.
I found some info about RUU but I need to re-lock the phone.
Does anyone have a solution ?
It just needs to boot once again, preferably on a CyanogenMod ROM ...

This is the first time I tried to install a custom rom. Please be gentle.
Device: Huawei Y300 (Bootloader unlocked and rooted)
TWRP Version: 2.5.0.1
Custom rom: cm-11-20140510-NIGHTLY-u8833.zip (found here)
I mindlessly tried to flash cyanogenmod 11 (kitkat) on my Huawei Y300. Here was the last steps I did:
copied rom and gapps zip files on phone root
restarted phone in fastboot mode
on ADB, ran
Code:
fastboot flash boot path\to\boot.img
(everything seem to be working fine)
ran
Code:
fastboot reboot
(phone rebooted in TWRP)
Tried to install cm-11-20140510-NIGHTLY-u8833.zip rom file (installation failed)
From what I read, the version of my twrp is not compatible with kitkat? Now i believe I bricked my phone because I forgot to create a backup of the stock rom.
Questions:
Is the stock rom still somehow there, hiding in my phone memory?
Is it possible to "undo"
Code:
fastboot flash boot path\to\boot.img
so that the "original" boot.img is used by my phone when I try to reboot it?
I am currently downloading Android SDK with a plan to upgrade my twrp for kitkat compatibility. I hope this will let me install cyanogenmod kitkat on my huawei. But I am not sure if I will succeed. If I still fail, can you guys tell me what other options I have to save my phone?
Thanks
Edit: problem solved.
I learned how to properly flash/upgrade twrp via fastboot.. Retried installing rom with twrp 2.7 and it was successful.
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 ? )
I was new to this twrp stuff, so i wanted to change my custom rom to stock rom on my lg k20 plus (model - mp260) And I couldnt find a way online to flash it, so i tried wiping all my data via twrp and i wiped everything because I had no knowledge, after that i rebooted my system and It showed the android screen for about 30 minutes. Then, i tried to reboot into twrp via adb, drivers arent recognized, tried to reboot in phone, bootloader unlocked message is preventing me from doing that. Can someone help please???
Hi,
I have a Sony Xperia Z2 Wifi tablet (SGP511). It currently has the outdated Cyanogenmod 12.1-20160807 (castor_windy). Because it has a lot of software issues, I decided to switch to a more recent ROM (since CM is discontinued). When I tried to access the CWM recovery I had before, I only got the Cyanogen recovery that came with the CM (where it is impossible to flash anything else but CM updates). So I decided to flash the recovery again using bootloader. The flash was done, but caused a startup loop. The sony logo is displayed and the device swiches off and on again, no matter if I leave it or try to access recovery. It seems that it is bricked, but I figured that by continuously pressing the red button besides the SD hole I can still force it to boot into the CM that is installed. So now I can boot into the old CM, and access bootloader by rebooting it via adb. What should I flash to gain back access to recovery?
Nevermind, I fixed it. By accessing the bootloader by ressetting the tablet using adb command I was able to flash the dual recovery from [NUT] . It worked, so I was able to flash the new AICP ROM from it.
Hello,
I have a H830tmobile, have had LineageOS for the past 7 months, but recently figured out I didnt have TWRP when trying to find a system file. While trying to install it, I got dumb and bricked my phone.
Thankfully I unbricked it that time, installed vannila ROM H83020i and downgraded to H83020a. I downgraded because it didnt let me use most fastboot commands and couldn't flash TWRP(flashing,booting,...), keep in mind it didn't let me on LineageOS too.
After that I rooted it using Hard Recovwery Method and flashed TWRP. Everything was going great until now, I found out that my phone doesnt show up on PC while in TWRP, would show up without problems in adb or fastboot. After continuing on through the guide, I formatted data, went back to boot into system and got a message that encryption was unsuccesful. Rebooted back into TWRP, searched for a fix and factory reset the phone, didn't help. I read that I should reformat only the System to ext4, did that and phone is without OS and boots endlessly. While trying to go into recovery mode through fastboot commands, it only sends me into endless boot and I can not get into TWRP and even if I could, I wouldn't be able to flash LineageOS as my phone just doesn't show up on PC.
Is this saveable or not?
ok booted into vanilla os again through uppercut, gonna try flashing lineageos only this time
