I flashed to G4HG-20130706-153833, GPS is better. But the new update is not stable on my phone. Many times phone froze when I run some application and I think that accest to phone memory is good only for G4 advance version.
Hello, the last rom is very good , but the problem for me is that there are , again, two partitition sdcard 0 and sdcard 1, and this is a problem.Please, how can I solve this problem.
Thanks in advance.
Can someone put the exact steps in updating the phone to latest ROM? I get error 8038 when I try to update, also sais that not all image files are correctly loaded when I press download.
I almost bricked my phone, SD version doesn't work, gives an error, and I flashed with FL, after a workaround (edit scatter emmc file)
.
for the sd rom:
1] extract the content of the downloaded zip file onto the root of your sd card
2] search for the "update" app on your phone
3] launch "update" app
4] sit back and wait for your phone to be updated
very good romfrom using it for a week but couldn't live without apps on the [external] sd card. i googled on how to link sdcard1 to sdcard0 and wasn't sure if i could achieve this so went for the easier route instead
what is the difference between JIAYU G4HG – FL – Update 07/06/2013 and
JIAYU G4HG – SD – Update 07/06/2013 I have to download both?
The difference I see an SD FL and the other the difference?
Hi,
will this rom work on a G4 Advanced?
I have one with the oficial rom G4HG 20130706-153833
This ROM is eating battery like mad, now my phone lasts less than 14h, and I have 3000 mah battery. I think I will try LEWA.
your phone have a proplem, maybe you need turn off all soft by hold "home"
Flashed it via sd card and it caused loads of problems, Tried to flash via FL, but it does work. Can anyone help? Soemone said they edited the scatter file to get it to flash. How do you do that and is it stable?
It's stable but something is eating battery. Default ROM was better related to battery backup, even if touch was kinda crap. And the bug with incoming call is still there and worse than before, can't answer. Scatter file must be edited, because it gives and error at FAT. Use google translate HERE
Hi, I need some explanations before upgrade my rom. At the moment on my Jiayu G4 I have installed the original factory rom 06/20/2013-163509. What files should I download and install from the "link" in this page? If I had to install more than one file, which one would go first and which last (i.e. what are the steps)? Please let me know, thanks. Bye, Giancarlo
the musik player have a problem …..
and the patery (3000mAh) is to fast low
