Black screen after "wipe data for all users" - General Questions and Answers

Hello all,
Sorry for my bad english.
I try to install new rom (fixed rom) on thl t11.
After i go in recovery mode i go in button "wipe all data" and after " yes - wipe data for all users"
Now when i turn on my mobile (power button) i get only black screen,nothing alse.
Please help me,is possible to fix this ?
Thanks a lot
Edit:
My phone is not rooted.also now i can't acces to my recovery .

did you fix that and if did how ?

By wiping your data you deleted the android system and data on your internal storage. But all your user data should still be there. However, since no operating system is installed, nothing can boot. That's why the screen stays black.
You will have to flash a ROM now. It must be suitable to your phone. You can either install the stock ROM oder a Custom ROM (which I would do since usually you have more options there). Download the zip-file to your sd-card and then flash it via the recovery, which you normally can enter by pressing certain buttons.
Which phone do you have? There a different ROMS out for most of the phones available. CyanogenMod for example is available for almost every phone. I would recommend getting that or the original firmware that was coming with your phone when you bought it.

[Q] LG MyTouch Bricked! Please help...

I went to clockworkmod's website and downloaded a cyanogen mod rom that they claimed was compatible with my device... Now the thing is bricked and I can't seem to recover the original rom... Anyone have any suggestions?
What do you see when you try to boot?Please explain little bit more. I have E739 too and CM7 works good for me.
go to the telephone service
When I turn the phone on the android on the skateboard shows up and that is all you see. It stays at that screen for about give minutes and then the system crashes.
I've tried every key combo I can think of to get it to go into recovery mode and or into clockwork mode, and nothing...
I've had that problem before. You didn't wipe data,cache and dalvik cache before installing CM7..you need to get into CWM recovery.. *From T-mobile website* To perform a master reset using hardware keys, follow these steps:
Turn off the phone.
Press and hold the Volume Down and Power keys.
Wait 3 seconds and press the Back and Menu keys.
Note: If you see the LG logo before pressing the Back and Menu keys, the reset hasnt been completed and you will need to restart.
Release the Power/Lock key after you see the LG logo.
Release the remaining keys after the LG logo flashes (blinks once).
The Android Unpacking screen appears.
The phone will restart and complete the factory reset.
Note: If you unintentionally press the Volume Down, Volume Up and Power keys simultaneously, the phone will display a circle icon with two arrows and 'S/W Upgrade, Please wait while upgrading...' message. You will need to pull the battery and restart

Hopefully you backed up your ROM before installing CM7..in CWM recovery use volume keys and power button to go to Backup/restore and then restore to most recent backup.

Moving to Q&A
@DarkLP: Already tried that, and it doesn't work on this model phone. I did wipe all the caches before restarting too. Not quite sure what to do next...
Timing is precise in getting into recovery, keep trying eventually you will get there, I have the same phone.
I bricked my phone too yesterday, I am really sad now. I was panicking and trying to save my phone but all it does is go into the LG logo, blinks once, and shows a half cut-off LG logo.. I tried doing that master reset thing.. are you sure it works? I'd dedicate all my time just to unbrick my phone

			
				
I was able to unbrick my phone the other day using Android SDK and the command prompt. What you need to do is have a backup of your ROM saved on your sd card. Use the command prompt to put the phone into CWM recovery mode and then choose the backup/restore option on your phone.
If the backup is stirred in the correct file on your sd card then the recovery program will automatically detect it. From there choose the file you want to install and then activate the restore process.
You should be good to go after that.
That is what i was going to say.
Ahaha I couldn't be any more happy, I went into recovery using that button combo trick, flashed C7 and a Kernel and Google Apps (you have to flash google apps if you want them) go to cyanogen mod wiki and find g-apps there. To get your cyanogen rom just google "lg mytouch roms" and you should click the android central link and then scroll down and someone posted the files for it. Only thing that went wrong is the Camera doesn't work..
It should be same as Dream G1, download a .pnh and Fastboot
Low end cheap bro.....
Tmobile Customer Service
TMO's customer service is pretty good. Call them and tell them you were installing a non market piece of software (true enough) and that your phone won't power on. They will walk you through some steps that might get you going and if not they will offer to replace your phone if it is still under warranty. I sent my defy back several times whaen I was learning to flash ROM's. Then, remember to wipe everything before you flash anything.
OK that doesn't make sense. once you root your phone, warranty gets voided.
yes i'm sure, I've had the same problem as you did. you need to keep trying.
so did you fix it?
If you are talking to me, yes I did manage to fix it and flash C7. But I want stock ROM back, anyone have the files and directions?
Now the phone wont boot into S/W mode and wont power unless powered on after my pc froze during the update

Greetings;
Have you solved your problem?
If not, tell me what Android version are you running on your device?
i.e: Gingerbread; Ice Cream Sandwich; Jelly Bean or KitKat.
Assuming you are running stock firmware i believe that either your brother flashed a wrong CF-Root for your device or used an application that could not root your device properly.
Either ways don't worry since your device can enter both Download and Recovery modes, it means that you can debug it.
[Rooting]
The best way to root this device is by flashing CF-Root file.
By flashing this file (CF-Root) you will be installing:
- ClockWork Mod Recovery
- Script that will root (automatically) your device.
- ext4 application. (do some research to know what ext4 is and how it os often used)
Small note: Since you will be rooted you will be able to overclock or underclock your device as well increase your device performance and battery duration.
Just PM me or do some research if you need some info regarding these configuration and settings.
[Fixing your issue]
Download Universal CF-Root here:
http://forum.xda-developers.com/showthread.php?t=1351056
Read the instructions before proceeding.
Now boot your device under Download Mode.
To do so:
Unplug USB Cable, Power Off your device and press the following key combination:
Vol.Down + Menu/Home Button + Power Button.
Release when the device enters download mode.
Now open Odin.
Under [PDA] load the CF Root File you've downloaded.
(Do NOT change any options inside odin if you dont know what they are for. Or you may get your device useless).
Put down your device so movement is done into the USB Cable (just to prevent bad flashing when you have low quality USB Cable).
Press Start and let the operation to complete.
Odin will display a message saying: "Pass" highlighted with Green.
Check if your device restarts (it may not restart yet)
If your device boots properly backup your data and follow the next step. If it doesnt boot properly follow to the next step.
Voot your device into recovery mode.
To do so: Power off your device and make sure it is not charging or connected to USB cable.
Then press and hold the following key combination:
Vol. Up + Menu/Home Button + Power Button.
Release after the Boot Logo is shown and you will enter recovery mode.
Now you will perform a Factory Reset.
Inside CWM select by the following order:
- Wipe Dalvik Cache
- Clean Cache
- Factory Reset
Note that Dalvik Cache is not shown at the main menu.
I dont remember the location exactly but if im not mistaken you can find it under "Advanced".
After you perform these 3 options the device shall reboot properly.
(it may take a little bit longer this time. Just be patient).
Since i dont know what was done to your device, there is still a chance that your device wont boot.
Either ways please let me / us (at XDA) know if it worked for you.
It is important (at least for me as a quality standard) that you are able to repair your device.
Best Regards
Please press thank button if this helped you. Since this will keep me motivated to continue helping.

Thanks for your reply. Frankly speaking I don't remember which Android version I was using may be Gingerbread (Is this important)
I downloaded "bagaria-09.GT-I9003_PDA.tar" from the link given by you and following procedure that you have mentioned. After odin says "Pass" I switched off my mobile and started in Recover mode it took around 15-20 mins to show recovery option. after this performed
- Wipe Dalvik Cache
- Clean Cache
- Factory Reset
and then Reboot. As you said phone is stucked on boot image for more than 15 mins then an loop on "SAMSUNG" logo after more 15 mins phone is showing "kernel panic upload mode"
Can you help me further?

Hello amoghs;
Again sorry for answering after so long; I'm not so often at XDA Lately.
Yes.
1st: Try Remove the Battery, then Put it Back and Try Again.
If this doens't Work:
1) Turn your Device Off and Press:
Vol. UP + Home Button + Power (To Enter CWM / Your Recovery Mode)
2) Select: "Factory Reset"
Let me know how it worked for you.
Note:
- After Flashing a ROM it is Normal that your Device Takes a little Longer to Boot on the "1st" time.
- Phone Stuck on Boot Logo and Looping: Boot Issues (Either Requires to Remove and Place Back the Battery; or Re-Flash the ROM or Stock Rom in a Difficult Stage).
Notes:
- After a Flash Perform a Factory Reset (To Clean Up Old Stuff).
- If you Experience: "Kernel Panic":
a) Remove Battery and Place it Back - (Works on Most Cases)
b) Flash your ROM again and DO NOT Instal Custom Kernel (May be Wrong Kernel or Bad/Incompatible Kernel Programming)
c) Phone Restarts by Himself: Reflash ROM, Try MinFreeManager or Similar APK (Application). Try "Optimal" Settings. (I dont recall the Presets names - But you can Safely test them - Even if device gets stuck. You can always revert to previous state).
d) Any Hard-to-Solve Issues: Just do a "Clean Flash" of STOCK Gingerbread (Check Sammobile Website - Invalid Download Links Just send email to Support Requesting the File)
or Flash "DDLF2 2.3.6 (Also Gingerbread). But always try Stock 1st to remove most issues, and only then Flash your Desired ROM.
Also if you haven't fixed the Boot Issue already: Do note that you can recover your device Boot.
NOT Dead Yet!
Please do let me know if you solved your Boot problem.
Best Regards;

[GUIDE] How to boot GT-I9070 in safe mode !

Hi guys! I searched how to boot in safe mode on our galaxy s advance and i dont found any topic like this.If exist one and i dont saw it,please delete this thread.
Im on cm and yesterday i tried option "Simulate secondary displays",because i was curious to see what it does.I touched this option,then i choosed a resolution ( 720x480 mdpi) from there.Then my phone rebooting and while charging bootanimation,bootanimation stopped ( was freeze ) and every reboot bootanimation still freeze.Now,i still dont know for what is this option,but i advise you to dont choose it,let it "none" to avoid bootanimation freeze.I had like 300-400 mb data for internet browser ( lol ) and others apps and i dont had a backup.But,i did a backup after i got bootanimation freeze and then clear data and cache and then restore just data,but got again bootanimation freeze,so will wont work.
If you choosed this option like me and you are searching how to solve this problem without lose anything,you must go in SAFE MODE.
What is Safe Mode ?
Safe mode is a great tool that you can use to troubleshoot these issues. Safe mode boots your phone running only the apps that came with the phone – that means no third-party apps. Therefore, if your phone runs without an issue when you’re in safe mode, it’s a pretty good bet that the problem isn’t system related, and instead a third party app you downloaded.
After i tried some combinations and searched on google how to boot in safe mode in others phones,i got one working for our galaxy s advance (i think work too for GT-I9070P ).
How to boot in safe mode:
1.Power off your phone.
2.Reboot your phone.
3.When you see bootanimation keep pressed menu button ( left bottom button ) until your phone boot.When your phone booted,you should see a “Safe Mode” watermark at the bottom left of the screen, to let you know that you are in fact in safe mode.
How to solve same problem which i had:
1.Power off your phone.
2.Reboot your phone.
3.When you see bootanimation keep pressed menu button ( left bottom button ) until your phone boot.When your phone booted,you should see a “Safe Mode” watermark at the bottom left of the screen, to let you know that you are in fact in safe mode.
4.Go to Settings > Developer options > Simulate seconday displays and choose "None".Then close settings.
5.Reboot your phone and wait until your phone boot.
Alternate method: If still dont work ( i think is impossible to not work ) follow these steps:
1.Make a full backup (you can make full backup if you stuck at bootanimation).
2.Flash cm again.
3.Reboot phone.
4.Power off phone.
5.Go to recovery and restore just data from backup (advanced restore).
6.Reboot (at this stage i was stuck at bootanimation again,i think you too).
7.Now do steps from How to.
Now,maybe you will have some lags (like me,is not caused by safe mode),just install some scripts,like Pure Performance script (work for our phone,tested by me) or any others scripts/tweaks.
I done alternate method because i was too scared after i got bootanimation freeze instead go to safe mode before do backup.Just follow first method (instead alternate method),must work.
Maybe safe mode will work too when you get bootloop after flashing something over a rom,so you will can boot in safe mode and delete what you flashed,im not sure if will work (i dont tried),but is better to make a backup when you consider that you have something important to avoid all problems.
In my case,i dont had a backup before to change "Simulate secondary displays" option,and safe mode was solution.
Before finish this thread,im sorry for my bad english Good luck !
Very good tip, thanks
Very helpful post, especially for those experimenter's like me lol
This is only for CyanogenMod right.... Or can it be done on other ROMs ?

[XT1032] Changing the firmware

Hi,
some time ago I tried to post my problem in general Help thread in this forum, but someone redirected me to post it directly here.
Hi,
I have a phone Motorola Moto G XT1032.
One day it turned off and I can't turn it on again - it displays the "planet picture" (which was always animating and then turning on), now it only hangs. I've tried literally everything in boot menu (or how you call it - pressing both "Power" and "Vol down" keys), all kind of factory resets etc.
Thus I decided that my only help would be to change firmware in this phone, but I've never did it before, so I'm looking for guidelines.
My telephone was not rooted, it was the ROM I got from the provider - it was pretty clean, but had a few Motorola apps preinstalled.
I wanted to install stock ROM, I've found this topic which looks nice: http://forum.xda-developers.com/moto...ction-t2854688
However:
a) I don't know what android version I had - it was surely some 4.4.x, it could be 4.4.4, but I'm not sure.
b) I don't know how to recognize whether I had stock ROM or Google Play Edition, as far as I can see there's difference in filesystems.
c) I don't know how to proceed with the instructions from this topic:
1) Download ROM to Internal SD.
2) Boot into Custom Recovery.
3) Factory Reset (System, Data, Cache, Dalvik)
4) Flash ROM zip, FOTA_Disabler.zip and reboot.
Click to expand...
Click to collapse
How should I download ROM to Internal SD, if in my case, I can't turn on my moto G?
Then I assume that custom recovery is the same thing I called above "boot menu" ("Power" + "Vol down") and "Factory reset" is one of the options I can find there.
And 4) is quite mysterious to me, except reboot part

Any help appreciated.
Well there's a GUIDE here on XDA some kind soul has written for you.
