[Q] YP-G1 resets when flashing factoryfs

I believe I ended up bricking my device after trying to fix a battery issue I had with CM10.2, where my device wouldn't charge. I had no access to recovery, only download mode. Trying to flash stock with heimdall and odin, i find that for both, when it is trying to flash factoryfs, the device reboots, and is sent from download mode into the one with the exclamation mark (forced download mode?). If I try to flash with either one in that mode as well, it will simply reboot back into the same thing. If I try to access recovery, it will result in a bootloop from the battery meter to a black screen until I enter back into download mode. I have tried this with and without kies installed, and have reinstalled drivers using zadig. Is there any way I can fix this issue?
EDIT: Managed to flash back to stock, but I no longer have my efs, nor can i find my previous efs backup. I tried use the dummy efs and have also edited out a few things, but I am still missing my lock screen and power menu.

Lenovo A390 rooting problem, using Framaroot and Rashr

I have a Lenovo A390 and I want to put a custom ROM that supports english and Google Play store app.
It is currently using some Chinese OS without google Play app, so not much I can do.
Current status: It is rooted but I can not access recovery mode.
I used:
1. Root - Framaroot with the Boromir exploit, worked fine initially. Then I used Rashr.
2. Install Recovery - Rashr let me install TWRP so I installed LenovoA390_recovery.img and tried to reboot to recovery mode. At first time it worked, and I saw the TWRP application screen and did a full backup of my Lenovo_A390. Then I tried to install a custom ROM and I chose the image file and started to flash it. It went very quick and I rebooted it. It started again but same operative system came up.
Once I restart the phone and try to go to recovery mode I see the old Lenovo logo or similar with a small text below that it is entering recovery mode, and then it goes to a black screen and nothing happens.
Now I can not access recovery mode anymore, then I hold volume up and power button, all I see after a few seconds is the Lenovo logotype, and nothing else happens afterwards. I have tried to install the recovery image again (using Rashr), but I have the same problem all the time. It installs the recovery.img but when I try to boot into recovery mode, it is not working. I also tried with CWM recovery image, but I get the same problem. Lenovo
The phone is still rooted (Rashr is working) but I can not access recovery mode.
How can I get the recovery mode to work again, so I can install a different ROM without Chinese operator branding?
Thank you!

Guys, What can I do if my screen turns black every time I try to go to RECOVERY mode?
The phone works fine, but when I try to go to recovery it JUST GOES black and I need to power it up again. How can I fix the recovery?
I have tried installing TWRP over Rashr, and it installs well, but just can not go to recovery mode.
Also, when I try to go to FASTBOOT MODE by holding POWER + VOLUM UP buttons, I only go to FACTORY MODE all the time.
Why is this happening like this, and WHY can't I go to FASTBOOT MODE?
Is it the same ?!?

Stuck in a bootloop after unroot, Coolpad E560 (Porto/Sky mini)

Hello! I rooted my Coolpad E560, a.k.a. Coolpad or Sky Mini and everything was fine until I decided to unroot it. It immediately restarted and will not boot ever since (stuck at logo). I opened recovery mode and selected wipe data/factory reset but it didn't solve the problem, neither did wipe cache. Then I selected reboot to bootloader. "Download and Install the package? Press volume up to agree or volume down to cancel". I press volume up and then it's stuck on "Information Do not disconnect the data cable". In the end I tried to flash stock rom. The only firmware I found was (phone name).CPB and it seems like the only flashing tool that can use .CPB is YGDP. But the flashing process doesn't even begin, it gets stuck on Entering download mode... I unsuccessfully tried to enter download mode on my phone. It doesn't have removable battery, some key combinations I tried didn't work. Now I don't know what to do. Any help will be appreciated.

Stuck in bootloop can access recovery no fastboot and no usb debugging..

Hi guys,
I own an InFocus m810 and had flashed a marshmallow based rom. It was all working fine until after 6 months my phone started to hang a lot so I decided to factory reset it... I tried to go to twrp but it wasn't going to recovery mode like it used to (by holding power and volume up buttons together) so I downloaded quick boot from play store and booted into recovery there I wiped my dalvik cache and all the files then I flashed supersu zip and rebooted but it's still stuck on the boot screen. I tried to go to recovery mode by trying all the combinations (vol up+ power, vol down+power,etc) but in vain... I even tried to flash my stock rom again by going to fast boot mode but it isn't even going to fast boot mode so that my pc can recognize it but it doesn't work.. when I press vol up+power(combination for recovery mode) it restarts and again go to boot logo and get stickers there... I looked over entire internet but everywhere it's telling to flash rom or wipe cache etc... but I can't even go to recovery and fast boot to wipe cache or flash rom please help me thanks.. i have an unlocked bootloader...
UPDATE: I can now access revovery (twrp) but when i cleared dalvik cache and went to reboot page it says no os installed...now i am worried to reboot it as i could loose access to recovery.... i cant find any recovery flashable rom ... there are some roms but they are only SUT(software upgrade tool) flashable any help would be appreciated..
