[Q] one click lag fix.. screen black, help!

Hi guys, I rooted my phone using z4root. I used titanium back up and set set to factory thing. and then i used one click lag fix the newest version and did one click lag fix v1+ and as soon as i did that my phone rebooted. but ive waited for more than 5 minutes and my screen is still black. and four bottom keys are lit. and galaxy s logo and sprint logo did show up but its still black....
so i read some things on forums and it said just take out battery and re insert it
and turn on. i did that and is still black.
omg. did i just brick my phone? i dont know what to do.
help!
The lag fix IS NOT for the Epic, I repeat IS NOT for the Epic. Odin your phone back to stock and start again.
how do i odin back?
You need to learn to search in the future, but here you go
http://forum.xda-developers.com/showthread.php?t=853209&highlight=ODIn
my epic 4g is 2.1 eclair does this matter?
No
Also don't make useless polls
sorry i was new and didnt know what that was
and thanks for your help
No problem, just remember to search before you flash/install anything that doesn't say it's for the Epic because I'm sure you don't want to have to go through this again.
sorry but whats the difference between ODEX version and DEOdexed version?
That would've been a perfect question to search to find the answer on, but the only difference is that DEODEX is if you want to install themes
i didnt do the odin thing but i did recovery thing and my phone became alive again. i did factory reset thing.. thank you. thank you!

Hi masters,
I have problem with my Samsung google nexus, firstly i purchased in singapore when i went to holiday so thecnical service is only valid in purchased conutry,

I have a galaxy nexus and for the past week it keeps telling me to install the new software update.

Take a look to the thread " unbrick and restore " from Tomsgt here you find a guide
galaxy tab 3 7
I have finally managed to fix the flickering screen by re installing a new firmware. Odin 3.07 wouldnt work, but odin 3.185 did for some reason!!! Now is there a root for this that won't put me in this position again. I am sure this has been asked and answered somewhere else, but I can't find it.
The previous root I did installed an old firmware, which caused the problem,
The auto display feature on this tablet still leaves the screen too dark,so I have had to disable this feature. Anny ideas anyone, thank in advance for any help

Go to dev Thread and usw the thread Cwm for sm-t210/r
http://forum.xda-developers.com/showthread.php?t=2433853
I had the same issue when i was stuck on boot loop, install a different recovery, i used CWM, and then install a different rom. Allot of the stuff here works across different platforms and it works fine but sometimes it cause the flicker.... good luck
I think you went into the developer options and clicked on the show screen updates. It will flicker all the time until you disselect it.

Sm-T800 stuck at Samsung logo start screen

I'll preface this by saying I have searched the forums here and after reading a few threads about similar problems to mine, I haven't been able to find a solution. So, I'm making a new thread in the hopes you fine individuals will be able to help me troubleshoot what's going on.
The problem:
I was running CM 12 on my T800 for a while, but after some bugs and random reboot issues, I decided to give the new IronRom a shot. I went ahead and flashed it through TWRP and everything went swimmingly. I was able to set up the tablet and use it for a while. However, two days ago when my wife was using the tablet, it randomly restarted while she was using it and then froze at the Samsung startup screen. It would show the screen, then blink to black like the tablet had restarted, show the screen and repeat this about 4 or 5 times before freezing at the Samsung start screen.
What I have tried doing:
First thing I tried was home+power+volume up to get into TWRP and do a wipe and start over. But I cannot get into recovery. Once the tablet is frozen the only way to get it to restart is with a hard reset power+volume down, nothing done after that seems to make any difference.
Second, I realized I could still get into download mode, so using ODIN I tried going back to stock. Flashed the stock rom for my region but when Odin is done with the initial flash, it reboots the tablet and everything is the same. Frozen at the Samsung screen.
I've tried flash TWRP again, but once the tablet reboots after download mode, it just freezes at the Samsung screen.
Any suggestions at this point would be welcome.
last time i had this same trouble but on my T705. I had to wipe everything including the internal storage. only then the device boot properly.

I would love to be able to, but as I said in the original post, I can't get the tablet to enter recovery, so I can't wipe it. The only thing I can get it to do is boot into download mode.
Hi, sorry to be that guy who bumps threads, but I'm still sitting here with a tablet I can't use and no more ideas on what I can do to fix it. I'd really appreciate any ideas at this point. Thanks again!

I had similar experience, and even started downloading official samsung image, with odin etc. However it looks like I was able to enter recovery if rebooting using the following sequence:
- power-vol_down-home combination until the screen goes black
- moving finger from volume-down to volume-up
-> waiting a few seconds (less than 10) until recovery screen shows up.
Then I just reinstalled the good old cm 12.1 (instead of the failing lineageos 14.1), and then all happy again.

Thanks for the link. I tried it but never could get the tablet turned off to see the battery icon. When I used the method in the link it just returned to the Samsung Galaxy Tab S startup screen

LG G8s Screen After Complete Factory restore, Screen Lost sync, then went Black

Hello.
I have an LG G8s that was functioning completelly well.
I did a full factory reset from the system settings (complete format).
The phone showed the typical message 'the phone will reboot twice', I left it over the table then pushed the button that says 'restore'.
It made the first erasing, then reboot but in the middle of that first boot the image of the LG logo went corrupted. Then it was corrupted all the time.
It seemed as if it had lost the screen syncing but still visible enough and the touch screen functioning completely ok.
I repeated the factory reset again, nothing changed, then I didn't try anything else.
Powered off, and on some time, all the same... 3 times powered off and on and then the screen went finally completely black.
Trying again off and on some times, all black.
For some reason during one boot the LG logo appeared perfectly well for 1 second and then again black...
"All Black" is now the situation...
Any ideas about how to fix it?
Please help!
Thank you in advance!

Let me guess,Android 12 was installed?I have seen reports where the A12 update is having problems with screen flicker,non-responsive touch screens and apps crashing!Go here,and grab the firmware of your model.Do a refurbish with LGUP.I would roll it back to the last A11 firmware and see what it does.I think you'll be fine on A11.I just updated my G8x this morning to A12,and I was watching it to see what it does myself.

Hmm... Interesting. News to me, but good to know. I guess I got lucky. I flashed my G8 (originally from US Cellular) with 3 different variants of A12 (UCL, Open CA, Open US), and didn't get any problems.

Yes,I was reading through Reddit about it the other day.Could be certain variants,which they didn't state which ones they was using.They did say it was all happening since the A12 update was pushed to their devices.On the other hand,could be a corrupt download which is odd because any update is verified before it ask to restart.

Hello.
Thank you so much for the answers, the info and the interest.
I have tried changing the ROM, my phone is detected as com port 5 but unfortunately LGUP doesn't detect it.
Also I have tried LG FANs firmware but when I push download the link is broken...
Any idea of what to do in order for LGUP to detect it?
Thank you so much in advance!
