[Q] Screen flickers at boot - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

As soon as I boot I get random lines / flickering unable to read screen. I cannot tell if I get in the recovery screen. Based on the noises I can tell it boots up. Since I can't read the screen at all, the software side will have to be done on my win 7 machine. Is there anything I can do?
I don't know the Kernel number or android build, etc. As I bought this on ebay.

Probably your build. I bought mine off of eBay too, broken though, and repaired it.
The first cm10 Rom I installed had that problem where it'd look like a static t.v. channel upon booting sometimes or it would just randomly do so while on. Resetting would be the only way to return the screen back to normal. Now two builds later, I have yet to re-experience that issue.
So I'd say keep resetting with volume down and power to get into recovery and install a new rom. The previous owner probably had a bad flash and wasn't able to restore the screen condition.
If that still doesn't work, correct me if I'm wrong, I believe you can rescue your tab with a factory reset using ADB, as long as you get into download mode.. which should be the first option on the right when launching the tab into recovery.
If you're unfamiliar with ADB like me, I can give you the steps in number counts to get your device into recovery and hard reset it.. like: click volume up once and hit power, hit volume down 4 times then power etc.

This probably will depend on the recovery that you have installed on the tablet, whether it's stock or custom.
This method is for clockwork recovery (CWM):
To get into recovery:
-Hold volume down + power buttons and release the power button once the "Galaxy Tab 10.1" logo shows (should be the first screen to even show). Continue holding volume down for a few more seconds and you should then be at a screen where you choose from download mode or recovery.
-Volume down
-Volume up
Once in recovery:
-Volume up 2x
-Power
-Volume down 5x
-Power
Your device should now be factory restored so you can just hold the power button until it restarts. If that still doesn't fix the issue, I'll look up the stock recovery procedure and you can try that.
Remember, volume UP is the 3rd button on the top left corner of the device and volume down is the second.

[Q] 2.2 on Vibrant gone wrong

I tried to upgrade to the 2.2 operating system using a guide on android forums.
I originally had a rooted 2.1 OS, I don't know if I unplugged it before the process was complete or if I had to return to a stock OS prior to upgrading; however now I cannot get to download mode to use Odin again.
I have read through some threads and I have a different case, I am not stuck at the Vibrant screen, I get past it. Upon boot up I get the Galaxy S screen followed by an Android System Recovery <3e> screen with some other texts. If I hold the power button, I will get the "Power Reset or Unknown Upload Mode" screen. If I continue to hold the power button, the phone will cycle between those three modes, the Galaxy S screen, the Android System Recovery screen, and the unknown upload mode screen.
I have and am still trying different key combinations to get back to recovery mode in attempts to reload the stock OS and then continue with the 2.2 upgrade.
I have made a video that I will post when I get home later today; any help will be appreciated.
Thanks.
What about pull battery plug in usb hold volume keys while placing battery back in DOWNLOAD MODE
Still flashing , thanks to odin & tw
You will be ok. Learn ODIN and you will have your phone back in a hour or so.

I am no expert by any means but perhaps the following might be of help:
try selecting reinstall packages when the stock recovery screen comes up, this may allow you to access CWM Recovery.
also try-- set up odin on Pc and plug in usb cable to Pc ONLY. Then with power off and phone not connected to Pc hold down both volume up and volume down and plug the usb in FROM computer this should take you to Download mode.
Try to reboot your phone with adb.
To get into download mode do this:
remove battery
replace battery
Hold both volume keys.
plug in USB
at no time touch the power button.
Takes me into download mode every time!

I forgot to mention that although in the android system recovery <3e> mode that I get I can scroll up and down using the vol keys but cannot select ANY options using the power key. None of the other keys can be used for selection either.

P3100 - no recovery and no odin mode

OK, i feel like a real noob now :crying:
I tried to upgrade my P3100 to Slim-p3100-4.2.2.build.6-OFFICIAL following the tutorial i found.
Result of this is that now tablet is non more able to enter either CWM recovery nor odin download mode and after normal boot i can only see a flashing Slim logo on the right part of the screen.
The best i am able to obtain is a "forced upload by key pressing" screen rebooting with all three buttons pressed.
Odin can see the device but when i try to re-upload cwm is stits in Establishing connection.
All threads i found in this forum were about phones and nothing about tablets. Anyone can give me an hint on next steps i should follow?
Thank you all

A small update:
I also tried to disconnect battery for 4 hours, but still unable to enter in recovery mode.
When you reach the slim logo, keep holding the power key for about 6,7 seconds. You will hear a vibration, leave the power key and immediately press vol up and power key again(do these steps fast after the vibration). When the galaxy tab 2 screen comes leave the power button, keep holding the vol button. Now check whether you can enter recovery now.

So, i tried tens of times, but nothing.....
flashing logo ---> power for several seconds till i head vibration --> as soon as i hear vibration leave power and faster as i can push vol up and power ---> release power as soon as Samsung logo appears ---> some colors on scree and slim logo again.....
Am i missing anything?
attached are photos of logo blinking
Nope. U didn't missed any thing.
U cant enter the recovery mode, must be a problem of recovery, try doing the same with power down, so that you can enter the download mode. Then odin can be used. Hope this works, and your tab becomes alive agan. All the best

[Q] Need Help. Volume Up not working, phone not booting and can't enter recovery mode

I have a problem. My volume up was not working very well for a while but it worked if you pressed it hard enough so I didn't go on about fixing it, because I was controlling volume within the settings. The problem got worse all the time and now it isn't working at all. And on top of that now my phone can't boot probably cause of some bad zip I was flashing while trying some mods for my rom (I am using Omega v51), and the phone stays on the omega droid walking screen and doesn't boot. Usually this would not be a problem because I would boot into recovery and reflash the rom, or wipe davlik and cache or fix permissions or whatever. But now with the volume up not working I can't go into recovery. I can't go into download mode either, to flash rom via odin, because, despite volume down button works ok, when you go into download mode you still have to press volume up to "continue".
Any other way to get into recovery or download mode without the use of volume rockers?
I even try with adb commands but they don't seem to work when the rom is booting...
PS. I don't think it's a problem of the volume rocker, rather it's a problem of the volume switch on the cable, because i removed the back panel and removed the volume button, and pressed the switch manually and it doesn't work either. I can order another cable from e-bay but it will take a while to arrive and in the meantime, I am stuck without a phone, so any help on getting in the recovery or download mode is appreciated.

Thanks for the answer. I thought of that but I don't have one and if i order one from e-bay it will take a while to arrive also. I am hoping for a solution that doesn't involve waiting that long
Just un update. Finally i got into download mode and stayed in the screen where you need to press volume up to go into download mode, removed the volume up button and pressed the up switch with a screwdriver hoping that at least one time it will be pressed and go into download mode and finally i was able to do that. So i reflashed the rom via odin and it booted into the rom. now volume up still not working, but at least I have a working phone until the parts from e-bay arrive to replace the faulty button and/or switch

[Q] THL W200s bricked by Exchange "wipe data"

A collegue thought it would be interesting to see what the wipe data command on Exchange would do to my phone.
It appears to have bricked it.
The phone boots, shows the THL logo for a few seconds then shows a dark grey screen.
Is this phone recoverable.
I am a complete noob, first post, so if it is recoverable I'm going to need real step by step basic instructions.
Hope there is somebody who can help.
Thanks.

A hard reset could save your life..
Press and hold the volume (-) button and then press the power button for about 3 seconds, release the volume (-) button when the screen comes and wait for repair menu. It's written in Chinese. Go to the part which is writing MMC at the end with the volume (-) button and press the power button. You are now in the hard reset menu, press the power button again and wait until the phone opens. That's all. You will lose all your programs which you installed before if you didn't back up before but the phone will work. I saved my W200S yesterday with same solution.
Thanks for your advice. I noticed the Chinese menu but I avoided it every time being afraid of not ruining something . Anyway, these days I've found out how to flash new ROMs so I am fooling around with trying different ROMs, I got allowance from my wife for this ). I am trying to fix an issue of the stock ROM, the proximity sensor doesn't light up the display when taking away from ear. The phone was not rooted so any attempt to enter engineering mode failed. Yesterday I discovered a MIUI ROM which looks very stylish and it solved the proximity sensor and even added the notification LED option (this was not included in the stock ROM). Now I have to test the battery life.

Bootloop to recovery issue.

Hi guys.
I seriously need help right now.
My friend bought an s2 i9100 in cheep which was stuck on bootloop and he thought it could be repaired.
so we don't know what caused the problem.
But i was surprised that few repair shops weren't able to fix it.
let me explain the problem:-
when we hold power button or plug in a charger it show the logo, goes into recovery and reboots repeating it in loop.
so whenever i charge it goes into this loop.
we can use volume up & down key in those 2-3 seconds in recovery but not the power key.
we can access download mode and it doesn't reboots automatically but going into recovery mode manually also start this loop.
it's like we are only going in recovery mode again & again.
i installed this file "I9100XWLPW_I9100ODDLPC_I9100DDLPB_HOME.tar.md5" through odin and also used the pit file "I9100_STOCK-System_2GB-Data_512MB-Preload.pit" but nothing changed.
i don't know what to do now.
i cant find any gingerbread rom to test.
i don't know how it can be fixed,
so please help me.
Update
After doing a lot of things I finally managed to boot into system but the problem is not solved.
I flashed i9100XXLSJ which had modem and CSC files other than the PDA only.
The device actually booted in system (just the samsung logo) but it was a bootloop.
This time I kept holding power button by which the bootloop stopped and it successfuly booted but power button is not working inside the system so I can't reboot, power off or even switch on the screen.
By holding down up vol + home + power for a considerable long time I can boot into recovery. But again the power button is not working so I can't select any option.
I flashed a cwm touch recovery which is working.
So can anyone tell me what is the problem here and what can I do to actually fix it.
If you have problems with flashing stock ROM, consider flashing a custom ROM, like Cyanogenmod.

Try flashing the 4.1.2 JellyBean leak ROM via ODIN linked in this thread (scroll down to you see "Another option for i9100"):
[GUIDE][Troubleshoot a failed Odin flash]
This will factory reset the device which may hopefully resolve your problems.

Actually the ROM you are talking about is the ROM which I flashed which is mentioned in my second post " update".
PDA = CODE_I9100XXLSJ.tar
PHONE = MODEM_I9100XXLS6.tar
CSC = CSC_HOME_OXX_I9100OXXLS1.tar.
That's how I got this far, previously it was impossible to boot into system.

In CWM touch recovery, you can swipe (or touch) to confirm the option.
Try factory reset. Reboot.
If that doesn't help, try wiping system, cache and data.
Let me know how that goes

Wiping data/factory reset and cache doesn't solve the problem.
There is format option in 'mounts and storage' so I formated system, data, cache & also emmc. But the bootloop is not gone. The only thing that is gone is the ROM because of those formats. I have yet to to install the ROM again.
maybe is a faulty power button... Do u have to push it down a little harder than normal?

It might be the problem of power button. Sometimes it boots as soon as I put the battery. It always boot when I plug in charger. Sometimes it boots after I press and hold the power key for maybe 15 second & sometimes it doesn't boot when holding power key & I have leave hold again to boot it. And important thing is when it boots, I have to hold the power key until the key lights up to stop it from bootloop but then the power is Jo longer functional in system. Same goes for recovery. But this is the only till nowROM which actually boots into system. Other ROMs were booting into recovery automatically.
I wanted to test cyanogenmod but I am not able to install twrp. I followed the steps here using HeimdallSuite https://twrp.me/devices/samsunggalaxys2i9100.html
I had no problem in the steps but the recovery is not actually replaced when I boot into it.
The recovery that I have currently is not able to flash isorec_twrp or any cyanogenmod directly. It always shows error code 7.
I am going to replace the power button with my friend's s2 (other friend who have an s2 laying around) only to see it works.
Anyways tell me how to install twrp successfuly.
The actual power button needs to soldered, I thought It would be a connector, so I am not going to do that. But as far as I can tell, the plastic button isn't the problem.
