Well I need to send in the Chacha because of some Hardware issues, so I'd like to restore the original ROM.
What's the easiest way getting it back (maybe with the option not having to root it again afterwards, or restoring the Clockwork-Backup)?
The best way is to download RUU, extract from it rom.zip and from that zip extract system.img, boot.img and recovery.img. Then flash those three via fastboot using these commands:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
And reboot your phone and you will have stock rom with stock recovery on it. Then you can use OTA update if available.
Can someone point me to a procedure to install a custom recovery. I'm currently on the stock recovery, have downloaded a CWM .img file, but don't know how to "flash" it using the stock recovery. Or is that not the way it's done at all? Thanks for the assistance.
Hi,
[GUIDE] Nexus 5 - How to Unlock Bootloader, Install Custom Recovery and Root
You need to flash it in fastboot. Boot into the boot loader and, fastboot flash recovery recovery.img. where recovery.img is the cwm image file
I can't seem to get TWRP or Cyanogen Recovery to flash succesfully CM12.1. They refuse to flash ROM zips, but do flash Gapps. I've tried ADB sideload to flash CM12.1, but ADB doesn't find my E3 no matter what I do. I go to recovery, and choose ADB sideload. Then I do adb devices and it just says "List of devices attached", but no devices. I can only use fastboot succesfully, which that made me think that I could decompress the zip and make the boot.img, system.img, and userdata.img out of it to flash through fastboot. I got all the required filesfrom the zip to make userdata.img and system.img (boot.img was already in there). I only have one problem: I haven't found a way to re-pack the files into the correct img format to be able to flash it through fastboot.
So, back to my question:
Has anyone managed to flash the CM12.1 zip successfully? If so, how?
Or, can someone show me how to repack the system files into system.img and the userdata files into userdata.img?
I recently tried to install multirom but it kinda messed up, Now I can't either do fastboot boot recovery.img or fastboot flash recovery.img cause none of them works. I also tried to recover stock firmware but it didn't help. any help is appreciated.
I can boot into stock recovery via fastboot boot recovery.img but cannot boot a twrp or cwm.
12S Ultra unofficial TWRP - link MEGA
Credit - UnofficialTWRP
They released TWRP under 12S Pro, but the code name is Thor which stands for 12S Ultra, and after flashing, I do confirm this is for 12S Ultra.
now they have a proper 12S Ultra section!
Download the image and rename as recovery.img for simplicity.
fastboot boot recovery.img (or full file name)
in TWRP, go to "Advanced" and "flash this twrp."
edit: the recovery image file is too large to be flashed directly via fastboot, so you need to boot first then flash using twrp!
edit2: backup and restore function may not be working properly on this version of twrp! I get boot loops everytime I do a full system backup and full restore after bricking the device, especially on the data partition. Clean installing rom then restoring data only still get boot loops. so use it with caution.
I suggest you to use 3rd party backup apps to do backups on apps and data, and stick to the flashing and other functions only for twrp.

Awesome thanks. But why not Fastboot flash recovery recovery.img?
No. You must type fastboot flash boot recovey. img

No I'm pretty sure it's:
fastboot flash recovery twrp.img
However my question was why the method outlined by @Nabicook vs this method. Is it because of the dual partition?

Because not only it is the method unofficialtwrp suggested, but also the size of the recovery img file is too large to be flashed via fastboot.
I already tried
fastboot flash recovery recovery.img
fastboot flash recovery_a recovery.img
and so on, but all failed.
only way to properly install this version of twrp is to boot first then let twrp to install itself to both a/b partitions.
Hi!
I'm following your guide...and after uploading recovery nothing happens
rebooting into recovery through ADB or just using buttons...still sends me into fastboot mode
What can I do?

are you sure you did
fastboot boot (your recovery file name).img
it should automatically boot into twrp without touching anything from fastboot mode.
then install twrp through the advanced option in twrp

Still having issues:
After flashing twrp + magisk, reboot sends me into fastboot mode ..
As I get it, previously I've messed up with boot image, flashing recovery into that partition
So question is:
Do I need to reflash stock boot.img (need help with getting it, stock recovery rom is packed into .bin and I'm unable to extract boot image
Or can I simply reflash stock ROM (in recovery or fastboot mode?)
*my phone is unlocked already

yeah you can try flashing stock boot img, and if that doesnt work, you can download fastboot rom and flash stock rom using flash all without wiping data(there is .bat file that says something like install without formatting).
That will fix any kind of brick issues of xiaomi device, and you just redo the twrp part.
