[Q] Bricked Galaxy Mini

Hi, I live in Egypt for a while and I bought last month a Mini. Everything was going just fine, I was using Odin many times to try new roms, and CWM Recovery to give a try to custom roms, without problems. Yesterday morning I flashed my device with the 2.3.6 rom that I found on this forum, apparently made for Latin America. Since that moment, my mobile is on boot loop, i can't do anything, I only can access downloading mode, I tried to reflash gingerbread 2.3.4, and2.3.5, it goes well, Odin gives me the PASS message, but still my mobile is forever rebooting at Samsung logo. I can't access recovery.
What to do? Is it bricked and do I have to send it to Samsung Center or is there hope to fix it by myself?
Thank you for any help...

u cant even enter recovery?if u can,just wipe cache and data..

Just remove the battery and stop your phone.
Put the battery in again.
Go to recovery mode by pressing Home + Power button at the same time.
In the reocevey choose wipe data/factory reset option.
Reboot your device after you are done.
You mobile will boot up fine.

Thank you for your answers but I wanna insists on a point: I can't access recovery at all, the phone show me the samsung logo for about half a second then restarts, and is looping in this state. No recovery, only downloading mode and RAMDUMP Mode (ARM9 mode) & Emergency Dload Mode (ARM9 Mode). Nothing else is avalaible.
Helppp

hey man i've already had that problem..coz i flash 2.3.6 and encountered same problem but i manage to fix it.. you need to enter recovery mode... Note: you need to hold the home & power button and wait for the samsung logo to flash TWICE (2X),when the 2nd logo flash, just realease the buttons and your on recovery mode.just wipe/ data reset.. right now im using Ginger bread 2.3.6JKVT and its rooted also.

No, I can't access recovery sorry.

Connect your phone to your laptop.
Use ADB
Type this :
adb shell reboot recovery
That will take you to download mode,then you can flash rom again. It would be easier if you have a CWM installed

If you can't access recovery either falsh CWM recovery or Flash another firmware from Download mode. If you want to flash CWM recovery just follow the link below for Galaxy Mini and search CWM recovery.

I tried many times, since i have this problem, to flash and reflash, official roms, CWR, but nothing works, setup goes fine according to Odin, but still have the problem on my phone, still only downloading mode works, and still a flashing screen, just during the samsung logo.

No one can help me with my mobile???

did you wait for the samsumg logo to flash tiwce while holding the combo key? you see when im installing firmware using odin my laptop turn off coz i dont have a battery i thought my mini was brick because the process was not finish,so what happen i tried to acces recovery mode its only shows a computer icon & phone icon. but i manage to fix the problem i go to download mode and flash again another firmware. and everything goes fine..so how come that you cant access recorvery...i would suggest that you flash a firmware with 4 parts not a single package.

just try this www*mediafire*com/?br3r8fod5g3vud4 flash this firmware with Odin this will surely work please replace * with . brace my post count is not enough to post outside link

As long as you can enter download mode... you are safe. If you can... just flash it back with Odin.

i had a same problem too.
my phone cannot power on, and ONLY download mode only working.
i flashed it for so many time too, and it doesn't seem to fix the problem.
so any fix on this ?

To ybregeon and Tre3,
I had the exact same issue, only Download Mode and RAM Dump, but could not enter recovery mode. Tried flashing many ROMs, oneclick unbrick, Heimdall recovery etc. but still no solutions available, I tried many-many tricks with no luck. So I went to Samsung Service Center, and it turned out that the problem is in the mainboard. It took me one night before Samsung replaced the mainboard from my phone and it's been working well since. All free of charge.
I hope your warranty is still valid. Good luck.

reflash the XXKPI/XXKPK 2.3.4 then flash the cmw, xxkpi and xxkpk is the safest stock gb rom to install

Flash odin and go to recovery mode and wipe.
It should work.

[Q] My phone is stuck in Galaxy note N7000 screen, can´t enter to recovery mode

Ok, so I Flash rocket rom on my note and when i rebooted the phone it stucks on the screen of samsung galaxy note, i can not enter to CMW mode so i can do anything...What do i do? i think i just screw up my cellphone please help me

Probably get a usb jig. Take your battery off.. Insert battery and connect jig. Your phone will boot into download mode. Then remove jig and connect your data cable and flash any stock Rom via odin

have did some battery pull for 5-10mins, use different pc, different usb cable... also no use.
Does that means i need to pay samsung to restore back for me?

Hello guys, even I am stuck factoryfs.img when trying to flash stock ROM.
I bricked my phone trying to install rocket ROM ICS.

PLEASE HELP

If you are able to enter recover, wipe cache, wipe delvic cache, wipe off data
then reflash

Not specific, you select any different, n as balok said connect directly to usb port, n close if antivirus running. Better download rom without antivirus, some time antivirus can cause problem, if any component of rom falsely consider as trojan.

That diagram you had is the same thing as the download mode. So treat it as such and flash your rom and kernel normally and it should work. I had the same problem before. To be sure, tried the following thread. Go to the 3rd post in this thread and follow the installation instruction. It will work. http://forum.xda-developers.com/showthread.php?t=1382055

I get that every now and then too. I reinstall the drivers (included with Kies), and reboot the computer. After that it will work.

Froyo to Gingerbread -- Please be extra careful when flashing

Does ODIN still recognize your Tab? If you are upgrading from froyo to gingerbread, you may need to load new PIT file as well as new dbdata.rfs.
If ODIN still recognize your Tab, try to download your choice of firmware again with PIT file included. I'll attach a working PIT for you.
Note: Please extract the attached file to get the .PIT file and put it on PIT field on ODIN along with your choice of firmware you are flashing.
Once you are done and reboot, mostlikely you'll be in a boot-loop stuck at SAMSUNG screen. Now reboot to download mode again, then flash the DBDATA.rfs.tar I attached on the following post in PDA field on ODIN:

If you can access download mode, its not a hard brick.
Just flash a stock firmware with Odin in downloading mode. After you get the "PASS" in Odin. Unplug the USB. Remove Battery and put it back. Go to Stock recovery, clear user data and cache and reboot.

I have this problem before and i managed to use ODIN3 v1.83 (can use Odin3 v3.07) to detect my phone and flash a stock rom onto the device. I followed the advice given on this excellent thread by Supermini.
http://forum.xda-developers.com/showthread.php?t=1071970
As mentioned on his thread make sure you have the latest stock firmware from the sammobile site or by using Check Fus Downloader as per the guide in Rafael thread http://forum.xda-developers.com/showthread.php?t=1551156, a working samsung USB driver to detect your mobile on your PC and a copy of ODIN3 v1.83 (or v1.84, v1.87, v3.07 run ODIN in administrator mode if using in windows). Ultimately if this this fails you could always try a USB jig which can be purchased from ebay, etc. to get the phone into download mode.
Good luck and if this helps make sure you send a thank you to Supermini.

So . . . last thing to rescue your phone is buy on e-bay or in other place JIG if it isn't help you then try in phone service and say you tried install new ROM with Kies and your phone is brick (maybe it'll work).

Say to Service Centre Representatives that you kept your at charging last night
And when you woke up
It was not booting up
Pretend as if you dunno anything about root or ROM
They fixed my bricked phone
I am not sure if I am breaking any forum rule by telling this

Hey bro sorry for the late reply also, please before you do anything else try following my instructions.
1) download Odin v3.07
2) source the stock firmware you want to flash from sammobile.
3) make sure you have the Samsung mobile driver.
4) open and run Odin as administrator and load the single file in the PDA and highlight the tick box.
5) shut the phone down and take out your Sim card.
6) put the mobile into download mode as normal (press both up/down vol keys +power)
7) connect the phone to the PC and check in Odin to make sure its com port is detected.
8) then flash through Odin as normal.
I understand what your saying about no download screen appearing, I have found through experience that custom kernels can cause no download screen to appear. Normally with stock kernel this is not a problem but with custom kernels sometimes all you get is a black screen. Ignore this and just make sure that Odin is detecting the phone and try to flash, chances are it will flash the stock ROM and kernel. If you get the setup connection error in Odin and the fail 0\1 just try another USB port on your PC and keep persevering.
Please keep us updated so we can help you if you need it.

Why will it be hardbricked if the custom roms are based on s5830i stock roms?

But it is probable that we did I not flash the rom properly as per procedure..so is there a chance that it be bricked? Else the rom may have some problem... just telling the probability
