i have been advised to flash the old rom using the sd card method
can any one guide me with the link related to the subject please? thanks

can you get into bootloader?. Have you try to flash via sdcard.

yes i can enter bootloader mood, and managed to install many roms but on startup still this black image appear, and i can not flash it by SDcard because (PSAS program of QMAT) can not connect to the cavalier exactly as active-sync

with the help of (OOKba) i managed to fix my CAVA with MTTY program, thank you very much

S-off problem
I can not complete s-off in step 3 it stops and say
hub 2-1:1.0: Unable to enumerate usb device on port 1
and then a lot of adresses vith 331, 343, 353, 361, 366 codes???

did you try to change usb port (i uvek ga kaci odnazad na plocu a ne spreda na kucistu)

Now it's solved, i changed ROM to oxygen, and it's works.

Anyone recognize this problem ?

My device is not S or Ion, it`s T, sorry for asking a question here, but maybe someone know about this problem and give ma an advice how can i solve it.
The problem is, when i flash f/w via Flashtool or simply upgrading f/w via SEUS, afetr flashing i get this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And the phone doesn`t boot. The only f/w that works normally after this issue is a f/w made by me in Flashtool, that was in phone from box. And the only way to successful flashing with any method, is the factory reset with internal storage wipe. If i do it from any working system, i can flash phone with any method, everything will be OK, but if i don`t do wipe, i`ll get this bug again and again. I don`t know why is this happens, maybe you van help me?
PS Bootloader is factory locked.

Remove battery and hold power button for 20sec and try plug in if u dont see anything i guess u should search for unbrinking threads

weird problems

A friend Gave me his hold g5s because of battery damage. I should see if I can do something with it. because I have no use for it I gave it back, now I have the phone again with a new problem.
boot loop
OEM Locked
literally no OS, firmware, or something...
I tried the "rescue and smart assistant" App for windows
by rescuing: "your device version is the last version..."
still Boot loop
with RSD Lite: device Properties = n/a
tried to unlock with bootloader ID (fastboot oem unlock code)
all this with Tools mode config enabled and disabled
the issue is now 2 1/2 years the same and now I'm literally at the end of my knowledge
I hope you can help me
we don't care if it has after all stock or custom firmware. it only needs to walk again
