[Q] DEEP Trouble, galaxy Tab 7

i really typed a big explanation regarding the problem, but i have no F*****G clue how it got erased. am already sad n pissed, well recently i tried to plug in my usb for my Galaxy Tab 7 running Overcome 7 ROM and Kernal 4.00.
but it dint get recognized at all, it hasnt happend before, but now i have tried every possible troubleshooting technique including kies troubleshooting and couple of em off google.
nothing has worked, and lastly i tried to install ChopSuey-v.9.1-SYNERGY_GODMODE-signed Kernal, coz for someone els it worked, but i totally bricked my tab, i used some android based software as odin doesnt know my tab exists, my hardisk is unable to mount and complete the factory reset all tat is failing.
right now no usb connection and my tab doesnt boot, doesnt recignize in download mode either!!!! please someone tell me what to do. i cnt take it to the service centre, am guessing theyll know its rooted and with custom rom thus voiding the warrenty.
it is stuck at the boot screen, and if i switch it off, it doesnt switch off just reboots , ad its stuck.
anybody any help?

i5500 problem with jig and entering download

hy guys,so recently I flashed gt i5500 with wrong firmware,some deoxed for s2 and samsung was hard bricked,it would not enter download mode even with jig so my dad took it to local service and they were in hurry so somehow they restored it to previous rom I had flashed it before deoxed and it was working perfectly,wifi and other functions,altough sim card was accepted,he didnt want to connect to network,normally he found network but didnt want to connect
so I restarted mobile phone,and now for some reason it wont start,I tried entering download mode with jig to flash another ROM,but no life signs,there are only white colour over black,so basically he is somehow "alive"
I didnt do anything him to cause that,and I don't know what to do next ? :crying:
no one knows anything ? some people say that he messed up with EFS,some say he deleted IMEI number ?
sorry for another BUMP,this forum is far less visited than others,I was today at local service and dropped my i5500 for repair,he checked battery and by voltage he concluded that maybe battery is completely dead and thats why phone wont even start
could that be reason ? i get white screen loop also when I connect to charger

Xperia X10 mini dead? :(

Hy all....i lost my Galaxy S4 and i got my hands on a Sony Ericsson Xperia X10 mini. First i wanted to put a custom rom on it with android 4.0...all i got was a boot loop. Then i wanted to put the stock rom back, it failed, and the phone now won't turn on at all, i can't even get into flash mode, nor recovery. My pc no longer recognizes it! I tried several things, but the problem persists... If i put my phone to charge, nothing appears on the screen. Does this happen to anyone before? I think it's dead forever . I will try to charge it for an hour or two, and i'll see what's going on. I accept any help and opinion!
Thanks in advance, and sorry for my english!
Edit: I went for a few hours of sleep, now when i connect my phone to the pc, the red led finally blinks, but the pc can't see the phone at all. Can't even get into flash mode...any advice?
Edit 2: I put the phone in to the wall charger and now it seems working (boot loop) but at least its not completely dead, i got my hope back!
What did you do next? Have you flashed it? How?
