help ... xda exec won't start after rom flashing

somebody please help ... just flashed my xda exec with the latest rom and now it won't start... When trying to hard reset it and just after pressing "0" in the white screen it won't boot... I plug in the mains charger and the orange light won't show either (so I can't know if it's charging). I'm not quite sure but I suspect that the main battery's red plastic lock-switch was in the "unlock" position during the flashing (but the battery was 100% full just before). Is that relevant ? Could this have drained the backup battery and that's the reason that it won't boot now ?? please help...

... what's the "bootloader mode" ??... (it's not documented in the user guide, is that a sequence after pressing 2-3 buttons together or something like that ?)
Put the Universal in bootloader mode by pressing Power + Light + Reset, which brings up an un-backlit screen with "Serial" at the top, and "v0.XX" at the bottom. (A lot of people get an error message if they are not in bootloader mode. They can install the ROM a second time. If you are in bootloader mode, you won't get an error message.)

dear kumar..i've tried for a few times...eventually i've tried to reinstall using the old rom..but its still hang....
i've contact o2 custpmer support ..they asked me to send it to the service centre...then i ask how to send and the charge would be (eventully i'm in malaysia right now) but they ask me to call the service and warranty centre personnally..
i've called them but the line was so bad and can't hear them clearly. Even so i've given my email address for them to email me their correct address for me to sent it..and their email address for me to communicate..but until now..no news....

What ROM did you guys flash? My suspicion is rising that one of the new AKU3.2 ROMS is the culprate, and that there is something wrong with one of them.

Got the same problem here after using PDAVIET...
No upgrade working
This happens with the uni sometimes regardless of rom. Remove the battery wait 5 minutes enter bootloader and reflash. If it doesnt work reflash again just the CE os rom. It will kick out in one of those. It usually helps to flash to operator stock rom first then back to wm6 or cooked WM5. (You have not hurt the device, the uni is a picky girl but always comes back

(SOS) Did I just brick my phone? (SOLVED)

I installed Nataly Rom on my phone and since that time, my phone start to hard reset more and more often (3 times today)
Now I don't think that this has anything to do with the rom, but more with my phone.
Now, If I turn on my phone, I just get my red vodafone screen and nothing else happens.
I tried a hard reset, even with a complete format, wich now puts my phone completly bank, but still it won't pass my red vodafone screen.
Does anyone have suggestions of how to boot it up again?
please help

try putting your phone into the bootloader screen and reflash with another rom.
I have a friend that had this problem with his phone. In his case there was a problem with the pagepool, installing a different rom as cobbs stated was the solution for him as well.

some of us have had this problem already - my advice- use tbe search function 'cmd task 29' is the answer
Hi Gort
Thanks for the wonderfull advise.
I already thought my phone was a gonner, but now I can work with it again.
For all the people who experience a phone that keeps hard resetting more often and eventually cant boot at all, here's what to do.
Procedure:
1. bring the device to bootloader.
2. Launch ActiveSync on PC
3. Go to connection settings
4. Uncheck the Allow USB Connection
5. Now, run mtty1_1_.42_538 on PC.
6. If you have run mtty1_1_.42_538, just press the button USB
7. Type CMD
8. Type task 29 and let the program do his work a bit.
9. after that, flash with the rom of your choice
here is the link to mtty1_1_.42_538
http://forum.xda-developers.com/showthread.php?t=490182&page=4
Thanks for all the help guys, most appreciated
and hopefully this thread will help others now as well
edit: Link updated, should work fine now

[Q] Ramdump and Boot loop error > Pls help !

Hello,
Yesterday, I buy my new i8150 Galaxy Wonder and i root my phone
I install the rom Black Notes Chapter 2 with ClockworkMod.
I used V6 Supercharger with scrip manager.
After the restart everything worked normally and I just installed Viber app.
Being tired, I have not verified if the scrip was properly installed
I go to bed and getting up several hours later, my i8150 galaxy displays a black screen with
RAMDUMP mode
<null>
I will restart my phone and there's only the Samsung logo that flashes every second.
No more access to Clockwormod, the logo flashes too.
The only thing I know to do is put it into Download Mode or RAMDUMP Mode > cause: force upload
So I try flashed an original rom (W I8150XXKK1 Galaxy (EUR)) into Download Mode with Odin Multi Downloader v4.43.
Every step is going well, but when it restarts automatically at the end of the process, the Samsung logo blinking again.
I also tried to reinstall ClockworkMod with Odin Multi Downloader, but still the stage proceeds successfully, always the same problem of flashing samsung logo on startup and no access to ClockworkMod
Help me please, it's been over 5 hours I'm looking for a solution.
THANK YOU
I'm not completely new to android, I trained for over a year with my ZTE Blade with different Rom (CyanogenMod)

No kidding, but the characteristic for the phone that possible have a boot loop are always have FORCE CLOSE app and doing RESTART itself
It can fixed but only if we get stock firmware with wipe and boot loader to fix this issue
I will bring this issue to new tread

This is EXACTLY what happened yesterday..and just now I wiped everything in the phone and turned it on. It worked first, but there was a FC on the start or something..and the screen goes black. But I notice that I'm still in the custom ROM I was using (GingerICE). Then I turned it off and and went to CWM. I tried reboot system now, but I was stuck in the samsung logo. Can someone help?
I have the backup of the stock ROM. Is it safe to make the backup?

if you could boot into Recovery screen, you could try:
wipe factory/system, wipe cache, advanced > wipe dalvik.
[careful] i usually format my /system if i get bootloops.
then reflash the ROM. reboot.. in my cases, those steps always worked.
edit: you should checkout the GingerICE with non OC version, the OC may work on some device and some don't, IMO if you're using your droid for daily use, i recommend using the non OC
im facing same issue too here... but i couldn't even access to download mode... tried many times, still failed... help plss...
Same thing happen to me ...today. I can get into download mode, but after flash the with odin it is still the same, boot loop on samsung logo.... help !!!

Try flashing the stock from the computer. Don't factory reset it. That might help you maybe.
