Impossible to install/boot on custom recovery

Hello,
I wanted to install the last Cyanogen snapshot for my LG G2 but I am not able to boot on custom recovery...
I tried many ways to install it, using for example:
- flashify
- MK802 CWM
- Mobo Daemon
- even Terminal
My G2 is an international version
I have now Lollipop 5.0.2 (build LX22G)
Software V30b-EUR-XX
I succeeded in rooting my phone, hopefully. But now when I want to boot on the custom recovery, I have this screen:
Erase all user data & restore default settings ?
No (Exit)
Yes

If I continue, I have the following issue:
Critical Error!
DemiGod Crash Handler : Critical Error!
Press key to choose Dload Mode or Reboot
[...]
Board Info
Rev : 1.1 speed, pvs : 1,1 serial : 038d0d1fa3d0cfbc

What can I do?
Thanks in advance for your help.
I found this topic, I don't know if it will help me:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076

i had same issue. I was able to get out if by turning off phone, pressing up button and inserting USB cable. That made phone boot up in download mode. Then I used LG flash utitlity to flash the stock kitkat rom.

You mean I have to flash the stock kitkat rom (sort of downgrade) and then flash anything I want?

No other feedback?

I finally found the solution!!!

If someone has the same issue, here is the solution.

I was on LG stock ROM, not CM. But I found the issue
(En effet, "unable" sonne beaucoup mieux, je n'y avais pas pensé, même si "impossible" ça passe je pense ^^)

Custom Binary Blocked by FRP Lock

After installing Super user through TWRP, my Phone: Galaxy Grand Prime 4G Dual SIM, SM-G531H encountered a problem in recovery mode
and says "Custom Binary Blocked by FRP Lock" and it is not booting.
1. Tried to flash using ODIN v3.10, while flashing it stucks at FRP Lock and fails the flashing process.
2. Tried Kies3, but it cannot identify my S/N
Please help me
Thanks you

The G531H is a dual sim model yes, but it is NOT 4G, it is a 3G only model.
FRP lock can be solved by reflashing to stock firmware (You'll need to make an account: https://samsung-firmware.org/download/GALAXY GRAND Prime/t1s5/UPO/G531HUBU0APE2/G531HUUB0APE2/ -Download an older one if that doesnt work. Also thats the uruguay firmware so double check for your country too)
- Use ODIN to flash this, it should work fine with v3.10. Click PDA or AP (Depending on ODIN) and add the firmware.
Then after setting up your phone, go to settings->about-> tap build number 7 times to activate developer options.
press the back key->developer options->enable manufacturer unlock. (NEVER UNTICK THIS UNLESS YOUR RUNNING UnROOTED STOCK)
Flash TWRP as normal, then flash flash the supersu.zip thats available here on the forums.
Hope it helps!

FRP Lock is enabled when you have a google account on your phone and if you modified your boot or recovery. To disable FRP, either remove the google account or restore the stock boot.img and/or the recovery.img if you modified it.

Then if you flashed recovery, can you boot into recovery ? If you can, then try to use sideload from recovery and restore your system.
If Odin stop when flashing system.img, check your USB wire, download an up to date Odin & Stock firmware, maybe your Firmware is corrupted somewhere.

I've been installing the frp locked twrp I do not know what the correct name is. AND
* I found an original cable there at home Samsung I do not know I'm believing it's cable I'll try to do it now. This Side load I'm afraid that it works the same twrp by and frp does not accept frp official program is blocking!
Does it work if I try to install it by the memory card or SD card?

If you have access to your phone, you can zero you PERSISTENT partition (that's how its called on my phone), its where android saves the FRP blocking infos. By zeroing it, you can run anything like before till google play service rewrite it again. I just do dd if=/dev/zero of=/dev/block/platform/soc.2/by-name/PERSISTENT, and I can boot to TWRP, but if I start phone to system, PERSISTENT gets rewritten again and then FRP lock turns on again, but I just made a script that runs when I shutdown phone that zero this partition so I don't have FRP anymore. :good:

No meu caso aqui eu preciso só instalar um Android que não está sendo restaurado ele trava no quando eu fecho ele ele não trava ele fica parado e não anda mais. Eu abro o Odin instalar boot recovery chegar na System link ele não passa ele fica parado carregando eu acho que é o cabo será
In my case here I only need to install an Android that is not being restored it locks in when I close it it does not lock it it stops and it does not walk anymore. I open Odin install boot recovery get on the System link it does not pass it stands still loading I think it's the cable will be.
Aqui eu só tenho acesso ao recovery e modo download no meu caso aqui tem alguma chance? e não tem depuração ativado não tem root eu tenho chance de restaurar conseguir salvar meu celular?
Here I only have access to recovery and download mode in my case here has any chance? and does not have debugging enabled does not have root do i have chance to restore able to save my cell phone?

Ha G531BT is a Marvell SoC, my bad x). Your only chance is to update your samsung drivers, Update Odin, download a fresh firmware and flash your phone. Don't touch the wire while flashing.

I give up I'm going to leave here, even if it's an hour to 5 hours, if I'm not going to sell the pieces

I'm not an expert, but I think that you have to install the stock recovery first.

Your recovery image is missing.. enter fastboot by turning off the phone, holding the vol- button and plugging in the phone. This should get you to fastboot from error mode. From there, flash the recovery.img extracted from an update.app file in huaweiUpdateExtractor from https://forum.xda-developers.com/showthread.php?t=2433454]

No puedo acceder a fastboot.... Siempre se reinicia y queda en esa pantalla

J7 Pro (sm-j730gm) rooting problems...

I have been trying to root my J7 Pro, however, I have been hindered by many obstacles. The first one was trying to install TWRP (i know it isn't necessary). When I tried, I was greeted with a fail on Odin and the error message "Only official released binaries are allowed to be flashed".
I tried to get around this by trying to unlock the bootloader through fastboot. When I tried to do so, the computer would just outright not detect the phone while in fastboot mode. Nothing will show up in the command prompt, nothing will show up in Device Manager, and I've tried to use all USB ports, which means both USB 2.0 and 3.0.
My next step is to flash the ROM to Nougat (phone is currently in Oreo) and try to get OEM unlock from there. This is where I started this post. Should I go ahead with downgrading my phone, then trying to flash TWRP, or is there another method?
Where I'm heading: https://forum.xda-developers.com/samsung-a-series-2017/how-to/guide-root-install-twrp-samsung-t3747535
P.S Yes, RMM is set to Prenormal.
Thanks!
Edit 1:
Literally found this 5 minutes ago, would this work for this particular case?

cara, vc conseguiu algo?
fiz o root e deu tudo certo! mas tive que reiniciar o celular e agora vejo a mensagem: "Only official released binaries are allowed to be flashed" no meu J7. O que fazer? Alguma forma de voltar? pode me ajudar?
Dude, you did it?
my root worked!... but I had to reboot the phone and now I see the message: "Only official released binaries are allowed to be flashed" in my J7.
What to do? Any way to get back? can you help me?
