It's been a year since I've been using my honor 6(h60-04). Updated to lollipop. Found too heavy for my device. So tried to roll back to emui3.0
As there was no official rollback yet I've decided to unlock bootloader and install cynogen mod for a change.
Boot loader unlock success.
Installing cwm succes.
Detecting cynogen mod in SD card NO SUCCESS..!!
Installed TWRP success.
Detecting cynogen mod success..!!
Installation failed.!! Error message this mod is for h60-04 and 02. Not for your device ( even it was download from honor 6 xda forum)
Got irritated. Decided to roll back to stock.
First time flashed recovery. IMG and system.IMG via adb and tried to boot using 3 button reset.
Did not go to recovery and Stuck in HUAWEI logo loop...!!
Tried to unbrick using multi tool. Same...!!!
Even tried manual flash using adb. Cust, boot, recovery, system userdata.
No change. Stuck in loop..:crying:
Searched Google, xda and more and tried everything. No help.
Decided to give it for repair. Technician directly said mother board problem...!!
If mother board problem how it can enter custom recovery....???!!!
Please guys.. Need help here... Please....:angel:

tried to install TWRP on chinese OP6, does not boot

Hello everybody,
I am currently in china and bought a new Oneplus 6 there. Unfortunately it comes with HydrogenOS installed here in China. I unlooked the bootloader without problems.
For installing the TWRP recovery i used this guide (https://forum.xda-developers.com/showpost.php?p=76635744&postcount=148).
However after i flashed the recovery (there where no error messages in the command promt), I tried to boot into the recovery. But now it seems that the TWRP Recovery is stuck... It stays at the boot screen. (even after a wait of 15 mins)
Is this guide not correct for a H2-OS Oneplus 6? What can I do now? I would be happy about every help i can get
Thank You!
It's not for HydrogenOS, coz now recovery is part of boot.img so when you flash it you brick your hydrogen .
You should flash the last official oxygen with fastboot after a wipe and then restart from scratch with OxygenOS
There is a topic with that ROM...

Redmi Note 7 Pro - Stuck in recovery mode

Hi,
I recently got a Note 7 pro from China as a gift and I flashed it to global rom using fastboot. But because there was an app that wasn't working anymore and people have suggested its because the phone is in unlocked mode, so I went ahead and used ADB to lock it and now it's stuck in this recovery mode 3.0. Does anybody know how to either reset the phone or bypass this? Thanks in advance.
First unlock bootloader & flash again with fastboot rom
Locking and re-unlocking the bootloader
To lock the bootloader, the device has to be clean installed in Fastboot mode. For the instructions, see this page.
Once a device has been unlocked, it can be locked and re-unlocked using the same account countless of times, anytime, on any official or custom ROM.

1. Unlocking the phone will never affect any app except Mi Find My Device or other Mi Security (that too it isn't much of an impact)
2.. Now use Mi Unlock to unlock the bootloader, since you already unlocked it would unlock immediately but will also format your phone..
3. Now never lock the bootloader while using a custom ROM
Just tried but won't work... it says that this account is not bound by this device. I think it's in a *bricked* state.
Same here. Cannot unlock. Tried fastboot install with miflashtool.
I think you sign out of mi account before locking bootloader if you have done this then you have to visit service centre, they will be able to flash as they have authorised account or else you can try extracting rom into adb folder & direct click on clear all.bat file if it works
Yes, this is the problem. My mistake was installing pixel experience. After install, the device don't boot up and goes în bootloop and I wasnt able to turn off the device. After, I boot up în fastboot and flashed fastboot stock rom. This rom relocked the bootloader but don't boot. The version of stock rom is the good one, only one from miui site for Redmi Note 7 pro available. My device don't boot and cannot install anything neither stock or custom. The recovery is now stock without the option to turn off or installing update. Maybe i will try @navi_58861170's method. Maybe it will work. În other case we must use edl method which is a little tricky. If you find another way, tell me.
Not working. Sadly.

In a recovery bootloop after Android 11 beta update? Here's how to fix that and keep your data and root.
I recently found myself in a predicament where I updated to the Android 11 Beta and stupidly reflashed TWRP (via TWRP A/B Retention Script magisk module), causing a recovery bootloop. I also could not get into fastboot mode via the hardware...

Realme U1 stuck

Hello guys
My realme U1 is stuck in bootloader after installing DOTOS via Twrp. can anyone guide me? and also can I install custom ROM at all? I tried multiple times but same thing happens...
Thanks in advance.... Please help
Mod Edit: Merged
I installed TWRP recovery via fastboot. Cleaned everything, tried to install DOTOS and it went successfully but my phone doesn't boot normally. It goes into bootloader and if I try to shutdown through TWRP it goes into bootloop. I thought maybe I bricked my phone. So I installed another ROM(linieage OS) and it also installed successfully but again booted into bootloader and after shutting down in TWRP via fastboot, it again went in bootloop. Tried different ROMs nothing seems to work...
