[Q] C6502 not booting up

Hello,
I tried flashing a custom rom today, went for pac man rom, unlocked my bootloader, flashed boot.img but forgot to put the zip in the phone, and couldn't sideload it because the phone wasn't detected by adb. I tried looking for a stock boot image, found one(by doomlord, latest firmware) , but when I flashed it and fastboot restart, the phone wouldn't boot up anymore, I just have the red led on all the time. When I press the reset button, the phone vibrates once, if I hold much, it vibrates thrice. I'm keeping the phone plugged in case it's a battery issue, but in the meantime, could anybody be of any help please?
Edit: if I long press the reset button and volume down, a green light blinks for a short time, and a new peripheral (S1) is detected by PC, but after a short time undetected by PC, and red light is turned on again.
Thanks in advance!

But First, try to put the ROMs and Gapps on the MicroSD by an Adapter with a computer. then try to get into Recovery and install.

Thanks for the quick reply, but I forgot to mention, I can't seem to access either recovery or fastboot mode.

waht colors do you have whaen the ZL reboot?

A blink green, then red stays on
Edit: I seem to have managed to get Fastboot mode by pressing reset and volume down, then releasing reset and holding power button as soon as the red light goes off. Now blue light. I'll try flashtool.

Ummm. Start the flash tool. And try to connect the phone in flash mode. Reg flash tool will show you if the phone is connecting or not. If connected in flash mode flash a tft Rom. The correct one of course.

[Q] Mysterious problems with used Phone... HELP!

Hi guys!
So, my sister got a Galaxy Ace II yesterday with some ode stuff, then I decided to install Cyanomod 11, BUT more problems appered:
1 - My Windows 7 (64bits) doesn't recognize the drivers.. so it no even list the phone as conected. I tried using Kies to detect and a bunch of packages of drivers of this smartphone model, but till now haven't made any progress... what can I do?
2 - I reseted the phone to original especifications by his own menu and tried to acess its Download and Recovery mode by pressing the 3 buttons at the same time(Vol UP + Home + Power), but for my surprise it didn't boot like it should, jus initializing normaly...what can I do?
3 - I realized, when it booted, that the boot animation has been changed, samsung logo doesn't apper ever and including I found some stuff installed that doesn't seem to be something that generic stock roms have instaled; this made me think that the room installed is not its stock. If that's so, maybe the problems listed above are resolved, but still so I don't know what to do...
I want to install Cyanomod 11, but need the phone recognized for Windows, it rooted and in download mode, but haven't find a way to begin if my computer doesn't reconize it...
Any Help?

2. did you hold the buttons? another way is to use quick reboot from play store
3. cyanogenmod has its own bootanimation -.-

Yes, I hold the 3 buttons at once and waited to it boot, but it jus performed the normal boot, it didn't get into download or recovery mode... I tried many times, but it's always the same...
And I know that CM has it's own boot animation, I know it, but it's not it this time... it's another one... and for what I know, it's not the samsung original one...

Having Kies installed is counterproductive to installing flashing drivers (and if you sync contacts and calendars with Google I can't even think of why you need it :angel
Try unplugging the cable while entering recovery, the LPM mode (charging while "off") screws it up (but download mode should work!)
And by "no Samsung logo", you mean not even the firmware's "Samsung GALAXY ACE 2 GT-i8160"? Sounds like you got a fake then...
But if it boots, you should check the Settings/About menu and tell us the "build version", often that's enough to know what ROM is on it now

Ryccardo, I installed Kies in the hope of having the drivers easylier recognized... But that was not my luck...
About that trick could you be more especific? Do I put the phone off with the cable plugged to PC and when I press both 3 buttons I unplug it?
About the version it is :
DM_BASE_12A_W12.43|sc6820_modem|11-02-2012
And this means that??? It's not the original one, right?
Thanks for the help in advance!

Recovery mode is: with power off, hold up+home+power (if it's on, it will reset since you're holding down power... keep holding it) and download mode is the same with down+home+power...
But that version is VERY dubious, the standard Ace never had "SC6820" (maybe it's the L model?) and I don't even think it was out at the start of 2012...

Strange, afaik galaxy ace 2 is shipped with 2.3.6 android.
Did you succed booting in downlaod mode ( Vol down + home + power )
you have to flash Stock JB and we will see what is going on

When I Google it I noticed it too..
No, I still couldn't reboot it nor in download nor in recovery mode...
Even doing what Ryccardo said, it still boots normally..

So could you please post a photo of the sticker under the battery (preferably with the entire inside back of the phone showing)?

Ah, sorry, I remember how much the <10 post restrictions sucked
But back to your problem, this is not an Ace 2... I suspected it since you posted that version number:
Googling "sc6820_modem" has http://www.pandawillforum.com/archive/index.php?t-18643.html at the end of the 1st page
2nd post there mentions "Star I8160"
Googling "Star i8160" on images shows http://www.gldron.com/media/tmp/catalog/product/6/4/64cfade20f06e0e31ffd853fb1f8009a.jpg as 5th result... while searching the version number on images shows a lot of Samsung clones...

Unfortunately you have fake galaxy ace 2 (
You cant intall any rom on that device

You surely can't use roms from these forums... There may be other roms for your device but you'll have to find out what it actually is first, which can be somewhat difficult...

Poor sister of mine.. She won't be happy in knowing this...
Anyway I wanna thank you Ryccardo and Rox!
You both Saved me a bunch of tie searching a solution that doesn't existed...
Thanks guys!

PixelXL bricked

Hi, sadly i just bricked my Pixel XL
ive installed newest system image trough fastboot, installed twrp rc1, super su, and after an reboot ive installed the ElementalX Kernel for 7.1.1., ive rebooted (all was fine).
Then ive remembered to see slot a and b in twrp restart,
ive loaded twrp, it was current Slot A, then ive hit Slot B and rebooted, since then my phone is just black, nothing on screen only sounds when on usb, like connected (dimdimdim).
tried already to hit different power + volume actions but still no luck.
Fastboot not recognizing an device, adb either.
Whats possible ?
thanks.

Have you tried holding the power button down for a long duration with it unplugged? It should after 30 seconds or so force the reboot

You might have to wait until the battery runs out to see if when it's plugged in to charge to see if anything happens!
I've never had an issue with a force reboot unless it's just a screen issue, which could be addressed with Google or whom you got it from

Try it on a different PC. Worked for me, when I bricked my Nexus 6, the same Way you did. Hope it works.

If you tried to boot slot b without first flashing a bootloader to slot b then you're screwed. That's a legit brick.

this is called a softbrick if there is still some life with the phone...the sound u get when the computer recognizes it.

then iam screwd, normally fastboot should install it on both slots, or iam wrong ?

its a hard brick, not softbrick because i cant load bootloader

might have to research what the differences of brick are. If there is no sign of life...screen turning on, flickering, or sounds thats a true brick. If the phones makes a noise after plugged into computer it is not a true brick aka soft brick.

I never heard of a soft brick being unfixable in my life period. I need to google it lol that's funny. Soft bricks are easy fixes. Why don't you fix it for him?

Maybe you should read more carefully. Hes not getting sounds from the phone itself. The computer makes a sound when he plugs it in cuz it recognizes a USB charging device. The phone can still recieve power from the computer regardless of the bootloader. However because he has no bootloader on his active slot he's toast.

It sounds like you may be booting into a low level Qualcomm boot mode. It is possible to recover with Qualcomm tools, but you would almost certianly need Google's specially signed versions.

brick after upgrade android 10

It seeems something wrong occurred (or interrupted ) during upgrade
I think the best youn can do is to repeat the process by means of usisg a full android image od android 10 on a sdboot card and reboot your unit by means of disconnecting it from battery or fuse
