Hi, I was checking and there's not much information on how to flash R720, so I decided to help with the way I do, and I have done many of them.
I will not take reponsability for a bad use or any problem caused on your phone, so please read carefully and go ahead.
BEFORE YOU DO ANYTHING MAKE A BACKUP BEFORE FLASHING !!!!
First download this package that contain everything you will use : d-h.st/zFgk
1- Turn your phone off and install with odin the file named: admire-cwm_2.tar
2- with the phone off, now press these 3 at the same time, power button, volume down and the back key and when shows the samsung logo, release the buttons and inmediately press volume up and home button and it will enter in to Recovery Mode, now install the file named: CM72RC1-Kernel.zip wipe data and wipe cache and power the phone off again.
3 - Enter to Recovery Mode again, and flash file named: Samsung-Admire-rc3.zip, wipe data and cache, reboot the phone and will be done.

I installed the stock firmware via odin but now my sgs2 is in boot-logo-loop please help me!
If the flash went all good which im guessing it did as you are trying to turn you phone on do this.
1. Turn your phone off
2. Hold Volume up + Home + Power on
3. This will bring up a menu with some options on it, select wipe data/factory reset then select wipe cache partition
4. Then on this Menu pick Reboot System
should work if it doesnt after this try reflashing your ROM.
I tried to flash a new rom, after wiping the data of my previus I noticed I haven't moved it into the external SD so I restared the mobile in order to move the .zip file.
At the point where you set a google account I tried to rush it though but at one point the phone restarted and from that moment on it always gets stuck in boot screen.I use the Omega rom.
How can I boot into CMW with "hotkeys" at the beggining of booting (Samsung logo)?
Things I tried:
Removing the batery for 1 min and restarting,
Almost all possible key combinations at the boot screen (Samsung boot) not the rom boot
CWM recovery
Hold down
Vol Up Button + Home Button + Power Button at first splash screen release buttons .

Normal 3-Button Combo should work. Maybe you have to be fast after insert the battery again.
If you can't go there, try to get into download mode a start a fresh install with odin or heimdall.

What is easier to use odin or heimdall?
ideally flash with odin to the T if your going to upgrade the rom to whatever you choose, it will do a full wipe for you bit of a pain losing your data but its really the only way of getting back up to scratch put it into download mode vol down - menu button + power button then an option will show press vol up and go from there be warned you must follow the odin instructions perfectly

Now i haven't tested beyond that but i found a youtube link for flashing stock rom via odin
https://www.youtube.com/watch?v=4ChtmNtpk3c
but this is in spanish so i translated in english here..
You must install Samsung KIES to ensure that your PC detects your phone.
After downloading install Odin
1 - Restart the phone in Download Mode ( Vol down , Home, Power Simultaneously ) .
press volume up to continue ( or vol down to leave but it can damage... )
2- Start Odin
3 - select files and press Start
Watch Out !!! Never unplug your phone before restarting
After 5-10 minutes your phone will reboot to your new ROM
stock rom download below:

Thank you very much! Although my SCH-i589 is currently hard brick, I think it will be very useful! -- Greetings from new members after 8 years
Can anyone please help me for a solution to recover my phone from it's bootloop state, I tried factory reset from stock recovery but it doesn't help, phone still unable to boot to homescreen. Been looking all over the Internet but no luck finding the firmware for ZTE blade S7 t920. I haven't enable the USB debugging on the settings so my pc doesn't detect the phone
Not sure if you manage to sort out you problem yet but you can download a ROM from the ztedevice dot com website and copy the update.zip file to the root directory of your memory card then you do the following:
Forced upgrade (for the phones that cannot be started or the phones that cannot enter standby state)
1) For a powered-off phone, press and hold both the volume key + and power key to enter into Recovery mode.
2) Press the volume key - to select apply update from sdcard, and press the power key to confirm it.
3) Press the volume key - to select the update.zip file, and press the power key to confirm it. The phone completes the upgrade process in about three minutes.
4) On the Upgrade Complete screen, select reboot system now and press the power key to confirm it.
Hi All,
I was in 20L ROM by eliminator. Wanted to reset my phone because I had some bluetooth and WIFi issues. After wiping System, Data and Cache I rebooted from TWRP and now it is stuck. If I remove battery and insert USB cable to it with Vol down, it enters "Welcome To Fast Boot Mode" screen and I am able to see my device listed from fastboot command from my Windows PC. But not sure about the next steps. Is my recovery gone too? Please advise with step by step instructions and kindly help me.
By the way, I was just trying fastboot flash recovery with a compatible version of TWRP and it says FAILED (remote: unknown command)
Help Please
Any help? I am stuck with dead phone

you "Never" i repeat "NEVER" wipe system it formats your system partition which contains all the OS solution is very simple.
1. Go into recovery mode to do this
a) pull battery out, and put it back in to make sure phone is completely powered off
b) Press and hold volume down + power button, as soon as phone lights up and shows LG logo release power button for just one second and press again untill you see a hardreset screen
c) on hard reset screen press vol - button on yes and press power button to select yes and do it again on next screen, it will lead you to TWRP Recovery
2. Now copy rom of your choice onto your external SD card and install it
hope it helps!!
