Stuck at the DOWNLOAD mode while the USB Connection Not Working - Galaxy S II Q&A, Help & Troubleshooting

Hi. I have an i9100 Samsung Galaxy S II. After purchasing, I flashed and installed a custom ROM on it (CYANOGEN) and everything was working perfectly.
Suddenly, USB stopped working as a media (it is working just for charging). It was strange because whenever I connect this specific phone to a NEW computer, it sees it for a few seconds then back to unrecognizing it. I though this could be a SW issue, I installed a new custom ROM (cant remember its name) but the same problem persisted.
Recently, I decided to revert to the official Samsung ROM (obtained from sammobile). I first tried this on another i9100 device (which did not have any problem), and everything went smooth.
When I tried to do the same to my faulty device, ODIN recognized it (surprisingly), and when I started the process, it wiped my device, and afterwards it stopped recognizing the USB port (again!!!).
Now I'm stock at the Download Mode, but no computer can see the phone to install the ROM (installing any ROM at this stage would be great )
Could anyone please advise if there is anything I could do to get out of this trouble?
Thanks

S2 doesent start after Stock Update

Hello,
I have a very big Problem. I was using SuperNexus ROM for my GS2 but because the system crashed sometimes and it was pretty unstable I wanted to go back to Stock ROM. So I downloaded the latest ROM for my GS2 from this site, the Official ROMs the newest one from Nordic Countries. Everything was fine and I also unpacked the zip and had the .tar.md5 so I opened the newest Version of Odin which was also attached to the Thread at the bottom and connected the device normally everything worked fine with no problems. Well I put the file in the PDA field and I checked Auto Reboot and F. Reset Time and clicked Start. It flashed everything normally with no Problem also it said at the end Success but then my phone rebooted and now it only shows me the Samsung Galaxy S II logo and it cant go any further I also cant get anymore in the Flash Menu with Volume Down + Home + Power what should I do???
Kind regards

*Fixed* I took out the battery for 5 Minutes and tried Download Mode again and then I flashed it again. Now it works perfect

[Q] [Fixed] MTK6589 - Flashtool readback killed BT/Wifi/GPS

Hello,
I've bought a new device - Evolveo StronPhone Q4, MTK6589 based phone. The stock ROM is basically vanilla Android 4.2.1. I've successfully rooted it using Framaroot.
Then I've created scatter file using MTK Droid Tools (all partitions that were formated were ext4).
Then I've decided to create a backup before I start playing with it, so I've tried backing up flash using SP Flash Tool (using Readback), it was running fine and downloaded approx. 20%, then crashed. I've tried that once or twice more times, always failed. Now after I plug it in, windows display "This device can perform faster" and FlashTool won't detect the device. If I connect it without battery with VolDn key pressed, FlashTool detects it and I get S_DL_GET_DRAM_SETTING_FAIL.
However, the phone boots fine, just GPS/Wifi/BT is not working. (No GPS icon appers, and I get errors like BT_open: WMT turn on BT fail in dmesg). Looks like an issue with kernel/HW issue.
Any ideas what could have gone wrong and how to fix it?
In the meantime, I've asked manufacturer for a stock FW image, but I'm not sure it helps...
Update: Okay, I have no clue what just happened. However I've unrooted, reverted everything I've modified on the phone so far so I'll be able to return it to manufacturer as "deffective"... And just for the curiosity connected it to the computer and tried downloading ROM one more time. And it succeeded - I'll upload the ROM once I get access to faster internet connection. I've removed the battery (phone was stuck in Preloader mode because I cancelled ongoing RAM test.), put it back and now everything works.
So, it looks like everything is fine now, however I'd love to know what happened, if you have any clue, please let me know!

Bricked s2 and cant install samsung usb modem driver

Ok so I bought a second hand s2 on a stock firmware then I flashed it with cyanogenmod 9. I then bought a mhl to HDMI cable and upon further info found out that cyanogenmod don't support mhl and apparently I needed a touchwiz rom, so I flashed a rom called chameleon and Viola my cable worked. I then looked into the multiwindow feature and decided to move to a rom with mhl and multiwindow support so I chose a rom called alliance rom. Everything seemed fine and then my data wasn't working for some reason, so I contacted my carrier (giffgaff) and they said they have blocked my data as the IMIE I have has been used before on multiple accounts for data abuse, I explained I have not done this but they said they would not remove the bar. I thought something was odd about this and upon further inspection I realised since I flashed my s2 my IMIE has changed to a weird 0049 number, I looked this up on Google and it says that this IMIE is a generic one and is caused by flashing sometimes. A lot of property seemed to have the same problem. As a solution to try and get my normal IMIE back I tried flashing back to a stock rom via recovery which has ended up bricking my s2 and I can't access recovery, only download mode. As this was the case I thought I'm gonna have to use Odin on the laptop to install stock rom but now I'm faced with a new problem. My PC wont install the Samsung USB modem, I have tried installing kies mini, installing the Samsung device drivers, installing pdanet al just to get the Samsung USB modem to install but it just doesn't. I've spent all day installing, rebooting, uninstalling, rebooting, reinstalling to no avail. So now I'm stuck with a laptop that can't read my s2 and forced to use my Samsung mini for internet and Downloading on a data plan (lucky its unilimited). Can anyone help me. Thanx in advance.
Honestly, to get this done as easily as possible, try another PC (and use paragraphs; attempting to read what you've posted was nightmarish & I almost didn't bother).

Bricked rooted Galaxy SII without CWM

Hello, let me describe my problem.
Some months ago i rooted my SGSII with stock rom to remove facebook and other unnecessary apps, but I didn't installed CWM. Yesterday I had a small accident. I dropped my phone on the wet floor and two problems occured. Power button didn't work and phone couldn't connect with network. After having dissasemblied and dried it inside, power button started working, but phone still couldn't connect. So I decided to make a full wipe. And here's come my problem. After wipe my Android 4.1.2 is able to go through initialisation process (language selection, wifi password etc.)
but after this it gets stuck and bootloop occur.
I tried to fix the phone using Odin, but after connecting to computer, it shows that device is unknown and Odin don't see it. I also tried to find way to install CWM via stock recovery, but it's propbably not possible.
Please, help me
