Bricked Captivate - Random dots on the screen instead of Download mode - Android Q&A, Help & Troubleshooting

Hi there,
I created thread under both general and android Q&A to have this post seen by as many experts as possible.
To brief the story:
Tried to upgrade my Rogers Captivate non-root Froyo to Gingerbread trough Kies the first attempt failed as after 30 min there was no progress on the installation bar, I disconnected the phone and restarted it, it booted up well and again I tried to upgrade. This time the bar filled up to 10% and then the screen on my phone went all Pink!! and the progress got stuck, then the phone was in semi-bricked state. I tried to flash back to 2.2 stock ROM on Odin 3 v1.82 the progress failed half way with a all purple screen (the green bar on Odin was almost at the beginning of the procedure). I thought to get it into DL mode once more to see if I could succeed but no DL mode anymore, all I get is random dots all over the screen!! and even when it gets connected on COM, ODIN cannot reach it anymore and it fails at Setup Connection. My belief is that my phone is bricked totally, but wanted to see if anybody on XDA has any thoughts for this.
Thanks for the help and time in advance.
Chrs.

[Q]Need help with with resetting phone

Alright I am completely clueless as to what to do and need help. Last night I tried to root my phone with the super one click. My phone froze at the Vibrant screen and was stuck there so I ended up bricking my phone. I looked online and found a couple of options and used the one click unbrick to unbrick it, then tried odin to get it back to the out of the box form. Well during this process, my computer froze and forced odin to close with the android download bar just starting. After that, I tried to restart odin with no luck. I pulled the battery and now only the soft keys light up and I can't get anything on the screen. Is there anything I can do or am I completely screwed?

[Q] Cellphone is looping at splash screen after kernel update

Hi everyone,
First of all, thanks for all the help/development done here, it is really awesome. I am new to rooting/rom so, I've spent a lot of time reading forum threads and looking at people's issues and it's been really helpful.
Yesterday, I spent all day trying to update my Bell Mobility Samsung Galaxy S Vibrant GT-I9000M from Froyo 2.2 to 4.2+
I sucessfully rooted the device, installed SpeedMod kernel(with Odin 3.04) and got CWM Recovery working when I restart the cellphone.
Afterward, I tried to update with different ROM(CyanFox, CM11, Mackay OmniROM...) but always got Status 7 error at CWM. So I figured I'd try to upate to a recent Kernel and installed GearKernel_JBPlus_Vibrant_1.0.3v.tar trought Odin. The phone got in an installation loop. Here is a poor webcam photo of the error(sry couldn't get better) : http://i.imgur.com/L3b0RmF.png. It says something like Estimating(?) volume for path [grep], Can't mount grep, Installation Aborted. Restart, splash screen, installation aborted, loop.
I had this loop at other occasions trying to update Kernel. The solution had been to put the cellphone in Download mode and reinstall Speedmod Kernel with Odin. This is what I did again.
It allowed me to get in Recovery mode but I couldn't go passed it. Attempt at restoring backup didn't worked. So I decided I'd go back to everything stock and followed this thread http://forum.xda-developers.com/showthread.php?t=1047087 and used Odin with the PIT and TAR files.
This got me in my worst position so far. If the cellphone is plugged, it loops between dark screen and the little "loading thingy" before the battery, but nothing more, no battery charge. If I try to open it without the plug, it display the GALAXY S GT-I9000 splash screen(which is weird cause I'm using I9000m) for a couple second then goes dark.. Then splash screen.. then dark... pretty quickly.
I can go in Download mode but I haven't succeeded to get in Recovery mode. I have adb on my computer but I haven't been able to call anything from it at the point I am.
I have found different threads showing different solution for various problems but I feel like I tried enough and I'd like to avoid bricking my cellphone so I decided I'd make my own post detailing the steps I took.
What should be my next step to get out of this loop? It seems like I only have Odin/Download mode to help me.
Thanks again.
If you have the gt-i9000m that is not the vibrant. The vibrant is the sgh-t959. Thats probably your problem

[Q] Sidekick 4G with Bootloop, Ive Tried Everything.

I have a bootlooping sidekick 4G that was rooted with SuperOneClick about 3 months ago. It was working perfectly until this morning I shut it off and powered it back on. The only thing I remember doing was downloading a couple of apps last night. I see green dots first when I power it on, then It goes to the screen logo and starts to bootloop. I have tried reaching the recovery screen but it just wont let me, although I do have access to the download screen. I tried to reset to stock firmware with heimdall but it fails when it trys to upload the modem at 99%. I searched the forums left and right for the sidekick 4g stock firmware to try to reset using odin but its full of broken links because my cell phone is so old. I really need my cell phone back and I just dont know what to do or where to go from here. PLEASE HELP!! Thank you.

[Q] Is my Galaxy S2 "Dead"?

Hello! So.. I have a problem and i sincerely don't know what to do. 3 days ago, after a day of use (everything went ok for a while) i came home, i grabbed the charger and pluged it into my phone so it can..charge(nothing out of ordinary). After like 1 hour, i took my phone, unpluged it from the charger and pressed the on/off button to open my phone, check my gmail,facebook, the usual..buuuuuut it won't open..
For the first couple of minutes i thought it was just a bug and tried to restart it(take the battery out, wait 1 minute, put it back in, press "the button" and so on) but still it would not start. RESEARCH TIME!
After this, i went online from my laptop and started looking for explanations regarding why is my phone (i am trying to avoid the word but..) maybe "bricked"..
Here is a video i found online that explains what my phone is behaving like: "*SOLVED* SAMSUNG GALAXY S2 wont turn on, in description"
(i can't post links )
IMPORTANT
- My S2 has the official software ( JB 4.1.2)
- Never rooted my phone
- Never tryed to change anything to the software
- Did a couple of factory resets in the last 1 and a half year just to refresh it(so it is not such an old phone)
- It is not under warranty
Ok.. after 1 day of research i tryed the following methods:
-went into recovery mode and did a factory reset to it, erased the cache, rebooted it etc..still nothing
-when i saw it was not working, i went further into the download mode. Odin on my computer, official firmware downloaded(4.1.2) ready to go..
After i waited for a couple of minutes so Odin would do it's magic, the little window( In odin, the one with factoryfs, cache,hidden etc.) reached the "Reset" status, the blue bar on my phone dissapread and it started to reboot.. but here everything got out of control.. my phone started to reboot like this: samsung logo on for a few seconds, and then the green android with the blue things spinning appeared on the screen but just for one second, and then, it was gone...and the phone started to repeat itself.. i mean the logo and the green android again and again, without any improovment and way to stop it.. so i pulled the battery out and started thinking for other solutions..
OK, after i saw this, i tried again with the 4.1.2 one, and then with the 4.0.4 one(i thought maybe an older soft would help me) but still it wouldn't go through all the way( ok honnestly i think this one was the one that wasn't stuck rlly on the green android screen but on the samsung startup screen with the S sign on)..
the end..
Sorry for the long story but i really don't know what to do with my phone
I am willing to listen to any solution you guys can offer..thanks :good:
Keep flashing different firmwares and take a look at this guide

Samsung Galaxy S9+ (G965F Dual Sim) Bricked/Bootloop

Hello XDA community,
I have a G965F that is permanently stuck on the first boot screen (Samsung Galaxy S9+ secured by Knox powered by Android) and it will not progress past this point. I have left it on for hours, and it just stays on that screen. Recovery mode does not work; if I try the button combination for it, it just stays on the same screen as mentioned before. However, I am able to get it into download mode. From here, I have tried flashing every firmware I possibly could, of course with the correct region and version, but nothing works, and the situation stays the same as mentioned before. Odin usually finishes up with no problems and reboots the phone, in which case the bootloop happens once again. On the rare occasion that Odin does fail, it will not boot even to the first splash screen but rather to the blue screen with the triangle, telling me to connect it to SmartSwitch and go from there. I have attempted this also, but SmartSwitch only gives some errors, and it fails.
The phone was on the stock firmware for a few years and even updated through Odin when OTA didn't work. It is a UK-unlocked Exynos device. About 2 years ago, I decided to switch to lineageOS using Neuroticals ROM, and that worked flawlessly, OTA updates and everything, 0 problems. I even went back to stock at some point and reinstalled Lineage shortly after because of how much it improved the device. About 9 months since I last did any type of flashing, the phone randomly froze while I was using it (I think the bottom half of the screen went black) and was totally unresponsive until I forced shut it down. This is where the aforementioned problem began.
I thought letting the battery run out would help, but it hasn't. One thing I have noticed is that it either charges very slowly or doesn't at all; it will only stay on for a maximum of a minute after it is unplugged. I left it for a few months, hoping to discharge it completely, but the problem persists.
Apologies for the lengthy post; I've used this site for about a decade for mods on various devices and it has solved all of my problems, but this is the first one that has really stumped me. For the past few months I've spent tens of hours searching various forums and webpages but can find very little about my specific problem. Thank you for any help in advance.
I will include pictures of the codes that download mode shows, and hopefully someone has some answers.
PS. For some reason current binary says "Custom (0x8)" after successfully flashing the stock firmware many times with Odin, but when Odin does fail it will show "Samsung Official". This I cant make heads or tails of.
