[Q] Can't overwrite current recovery? - Acer Iconia A500

My relative's A500 has TWRP 2.1.3 running (extremely old version) and I'm trying to replace it with CWM 6.0.4.5. I did the following in fastboot
fastboot erase secboot
fastboot flash secboot recovery.img
But when I boot into recovery it's still TWRP . What am I doing wrong? The tablet is running Skrilax_CZ V8 bootloader, I want to update that to V9 and the use CWM to be safe since that's what's recommended in the thread. Any advice would be appreciated.
Thanks

Figured it out, have to boot into second boot :silly: . Mods can close this thread

[Q] How to root CM12S Stock..? [SOLVED]

Guys I am unable to root CM12S because none of custom recoveries are booting.
Initially I tried Doomlord's hotboot recovery flash method. I have tried twrp 2.8.6.0 , it enters into grey screen. Cwm and Philz recovery enters into black screen.
fastboot -i 0x1ebf boot recovery-yu.img
Secondly I tried actually flashing the recovery and the result was the same.
fastboot -i 0x1ebf flash recovery recovery-yu.img
So how do we root CM12S....? If anyone has managed rooting do share your method.
Thanks in advance..!
[SOLVED] : Used 64 bit twrp recovery meant for lollipop from this thread HERE

MX4 bootloop brick after trying to update I firmware on A phone

SOLVED:
Hi,
I just bricked my MX4 after trying to update system image from 4.5.6 to 4.5.7 using this guide:
Extract I version update.zip
use sdat2img to create system image
dd system image to system partition on live phone and reboot.
I used the same procedure successfully before, x-updating 4.5.4A ti I then updating to 4.5.6I.
After updating to 4.5.7, the phone goes into an infinite loop of Meizu splash screen, Flyme balloon, reboot.
I can enter fastboot and official recovery, but can't flash any partition from fastboot.
The bootloader is still locked.
Does anyone have any advice for unbricking?
Update:
The bootloop suddenly froze up for long enough for me to use adb to push an update.zip to the "sdcard" root. Have now flashed 4.2.8A from recovery and booted the phone.
As I had to clear all data I will unlock bootloader before trying anything else.
Try do flash 4.2.8.2 with uboot.img modded (to reunlock bootloader) and reboot fastboot and tell me

Hi,
I managed to push 4.2.8.2 to sdcard then do a normal recovery reflash.
Have now successfully unlocked using the .apk method.
Now I need to find out if I can use that unlocked bootloader to flash recent "I" firmwares, or if I can only flash the unfinished cyanogen (would like to wait 'til that's a bit more polished before using it.
Anyway. Happy to have my phone back!
Maybe that newest 4.5.7I need a new kernel so you'll need to update to 4.5.7A before flashing system.img or you can flash directly 4.5.7I but you'll need to use fastboot flash boot boot.img
If a rom/firmware needs a specific kernel it'll bootloop if you don't flash it
Can I flash 4.5.7 I now that I have unlocked bootloader and custom recovery? If I understand the unlock threads correctly, I think I will relock the bootloader, or even brick if I try to flash the complete update.zip. Can I flash system and boot partitions using fastboot?
Fully BRICKED.
Now I FULLY bricked it (no more recovery).
Had successfully upgraded to 4.5.7 "I" and was installing super su for full root, before disabling update, but had forgotten that I still had official 4.2.8 rom as update.zip on "sdcard" root.
rebooted to TWRP recovery for full su install and recovery found the update.zip and flashed it.
Result: Bootloop, No recovery, locked fastboot, no possibility to flash anything.
Aaargh!
Where do I find a 4.2.8 recovery.img for this phone?
Maybe there's a possibility doing a fastboot boot recovery.img ???
NOPE:
[email protected]:/home/marius/Downloads# fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.662s]
booting...
FAILED (remote: unknown command)
Fixed with large hammer! Goodbye Meizu!

fastboot boot recovery.img isn't a command at all... It's fastboot flash recovery C:/path/to/recovery.img

[Help] No more bootloader after full ASUS-ROM reinstallation

Hi,
After rooting my ZE500KL doing some stupid operations (like breaking gapps with Titanium backup), I decided to make a full factory reinitialisation with UL-ASUS_Z00E-WW-12.8.5.106-user.zip..
That's work fine, but I can't boot to bootloader any more with power+sound key combination or adb reboot bootloader: boot never finalize.
Information: The recovery boot correctly.
Anyone can help me ?
Try flash .156
It updated bootloader, so it should fix your problem.
After that, you can downgrade to .118 if you want (best version for rooting, imho)
Go to this http://forum.xda-developers.com/zenfone-2-laser/general/wip-finding-to-root-ze500kl-t3223797
and download Original boot.img and Official recovery then use ADB to flash your bootloader
-adb device
-adb reboot bootloader
-fastboot devices
-fastboot flash boot boot.img
-fastboot flash OfficialRecovery.img
-fastboot boot boot.img
try it.

Twrp fastboot

Is it possible to fastboot flash recocery twrp.img to get twrp back if i had to flash stock recovery img for something. Given im running custom ROM.

Nexus 6p with custom recovery is in bootloop!

Hi there! I recently got my first android phone so wanted to install Lineage os 15.1 but messed it up right away as it's in now in boot loop! Here's what I did:
It was on Android 8.0 angler-opr5.170623.011-factory-0e60ceb6 but I unlocked its boot loader and installed custom recovery and I successfully flashed in the fastboot , vendor, radio and boot loader from Lineage OS 15.1 thread, now instead of following the rest of instructions, I madly decided to reboot the device using fastboot reboot and now I don't see anything except these colored circles which is what boot loop probably is! Please help me find a solution! Thank you!
edited: I have successfully entered into bootloader mode but don't know how to proceed!
I'd flash all the stock firmware in bootloader and start over. Grab the latest firmware package from Google's site, extract it, then run:
fastboot flash bootloader bootloader.img (name changes with version)
fastboot reboot-bootloader
fastboot flash radio radio.img (name changes with version)
fastboot reboot-bootloader
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash vendor vendor.img
Reboot to system
You'll probably have to flash your custom recovery again in bootloader after the first boot. It usually reverts back to stock.

Part 10 in the thread above^
I recommend you installing an easy official ROM.
With them all you need to do is a clean flash of the ROM
Since I'm still a noob so I need to muster up courage to proceed but I really appreciate your valuable input guys!! Cheers!! :good:
edited: I have successfully installed stock firmware! cheers!
