black screen - Nexus S Q&A, Help & Troubleshooting

Hi,
I´ve tried to use "root live logcat". This app is supposed to show logcat during phone boot, but I got black screen instead. Phone will boot but I´d need to know how can I remove black screen.
I tried to uninstall root live logcat and copy new bootanimation.zip into data/local and system/media but it didn´t help.

If you select wipe data/factory reset...you will lose everything that isn't saved to your USB storage. You should be fine with just flashing the ROM without the data/factory wipe. Just make sure to wipe your cache and Dalvik!

What betoishly says. Wiping cache and dalvik cache does not affect your apps/data. Only if you do factory reset you wipe everything.

For the record, this solution did not work. Any other suggestions?
After wiping the cache partition and Dalvek cache, the phone continued to boot with a black screen. It then went to an "Android is upgrading..." screen and Optimize every single one of my apps (128). Nothing was messed up.

[Q] I am Bricked....i think

Ok, So i rooted my T-mobile G2x 2.3.3 and there were difficulties when i flashed the Cyanogen 7mod. The Rom worked but the only default was i didnt get data. Like i couldnt even get Edge. The only way to use internet and stuff was through wifi. SO then i reflashed it thinking it was a bad flash. But when i reflash through rom manager it gives me the option to downoad with google apps. so i clicked that option. It downloaded fine but on the reboot it stayed stuck on the 2nd LG screen. Am i bricked or if anyone can help id appreciate it alot.
U can't do it via rom manager. U have to flash recovery using nv flash, then u can try to flash custom rom. Remeber to wipe data and format system before flashing any rom.
U r not bricked yet
Check here to nv flash the cwm

Did you flash CWM via NV Flash. If not, do that. Then boot into recovery by holding down the power + volume down keys until you get the second boot logo. Then wipe the dalvik cache and the regular cache. That is usually why a phone refuses to boot.
Also, if your phone turns on it is not bricked. Bricked means when you press the power button nothing happens at all. You can be soft-bricked like you are, but it can be easily fixed. Nothing to panic about.
I did all of that im sorry if i gave you info wrong. Like i cant do anything it turns on but goes to the first LG screen then goes to the new LG screen with the blue streaks and it stays there. Then when i try to go into CWR it shows the LG with a blue and black loading bar below then shows as if its loading something then it just goes back to the blue LG screen and im stuck there.

You have stock recovery on the recovery partition, not CWM. You MUST flash CWM onto the physical recovery partition using NVFlash with the One Click flasher. You used Rom Manager and that doesn't install CWM onto the recovery partition. Once you have CWM properly installed you can enter recovery and revive your phone.

@OP, this is is correct. Use tga gunmann's nvflash tool from the development section. The process is super easy. Just make sure to follow his instructions closely. Just fyi, most people get errors during the nvflash process because they don't install the apx drivers appropriately, so take your time and read the instructions carefully.

Start off by wiping cache and then go to Advanced and wipe dalvik cache. If you still can't boot after that then try a full factory reset.
Just remember the first boot after wiping dalvik cache can take several minutes as android rebuilds the dalvik cache. All subsequent reboots will be MUCH faster.

Did you do as phburks said and go into advanced and wipe the Dalvik Cache. Most issues of not booting are related to the Dalvik Cache not being wiped after flashing a new rom. That is essential to getting your phone to boot again. A factory reset DOES NOT clear the Dalvik Cache.

Boot back into cwm, go to Mounts and Storage, format /system and then reflash your rom.

Could be a bad download. I'd try downloading again. Use your computer to download again and save it to your microsd card. Then reinsert the sdcard, boot back into cwm and try again.

The reason I ask is that with cm7 you have to flash 2 separate zip files. First you flash the actual cm7 zip which installs the rom and then you flash the gapps zip which installs the Google apps (market, gmail, etc). Make sure you have both on your sdcard and then flash the rom first and gapps second.

Im glad you brought that up because when i first flashed Cyanogen i did also flash gapps but after i flashed gapps thats when i wouldnt get data. Do you know the reason for this? or was it could have been another bad flash?

Not sure. I'd just play it safe, re-download both, wipe data, and reflash both. Sometimes its hard to determine which step went wrong and its best and quicker to just start with a clean slate and redo everything.
I wont be able to post for a while so good luck.

[Q] Phone doesn't boot

Yesterday i preformed a hot reboot because my phone was not installing apps correctly. I used the app Hot Reboot. When i looked at my phone again this morning it was still booting! I took the battery out and back again and pressed the power button. But how i try it keeps booting all the time! I can get into all boot modes but i don't want to flash a whole new rom 'cause i haven't backup all my stuff... What can I do? Will this be solved with flashing for example a new kernel or anything wich doen't reset my phone? I'd really appreciatie help!
Try clearing the cache and the dalvik cache in recovery, if that doesn't work tho you will most likley have to do a full wipe and re-install your rom.

Tnx but my phone still keeps on booting after wiping cache. Is there maybe a way to backup all my system 'n data files using adb or something?
It also happened to me this morning...u may again flash your device with the stock roms (froyo or gingerbread) again by using Odin Multi downloader...first power off the phone..then hold volume down+home+power on
To bring into download mode
Then flash the roms...it should restart....at least worked for me

Go into recovery mode and then go to backup and restore and then select backup. It usually takes a little while backing up the system so be patient.

I don't have clockworkmod recovery. Can I just flash the latest version of g3mod (wich involves cwmrecovery)? Doesn't it reset my phone if I flash that?
But are there no possibilities using adb? Because i run one of the first g3mod kernels...

Just flash the latest G3MOD kernel and use the CWM from that. It won't wipe any data whatsoever but if you get force closes it is recommended that you wipe the data from CWM. I don't really know how to use ADB but i think rudolf895 has a tutorial on youtube. Google 'rudolf895' and find his video that is called how to make your own custom ROM.

System UI crashed

Guys in random times my UI crash and system inform me that UI was stop. Then I pick ok and the device returns to the lock screen. I haven't any ROM, I use the official 6.0.1 version. Can you give me a solution please?

Do you need some advanced recovery to do this?
No advanced recovery is required. Just boot into recovery and wipe cache, don't wipe data or factory reset.

Try clearing app data of SystemUI from the system settings. You could also uninstall the last apps you installed/updated.
Also try recording a log. It may help.

Try a smaller Gapps package than the one that you flashed with the ROM. The package you used is probably too large to fit in the system partition along with the ROM.
Or, you didn't factory reset, wipe cache and wipe dalvik cache when you flashed the ROM. Failing to do those wipes will cause bugs due to the new system conflicting with the saved system data/settings from the previous system. In other words, data left over from the old ROM is causing problems with the new ROM.

Boot back into recovery, then factory reset, wipe cache and wipe dalvik cache, then reboot.
If that doesn't work, try booting back into recovery then flash the ROM then the Gapps then factory reset, wipe cache and wipe dalvik cache then reboot.
If that doesn't work, try booting back into recovery, then select the "Wipe" option, then choose the "advanced wipes" option, then choose the system partition, then swipe the slider at the bottom to run the wipe, then try flashing just the ROM but don't flash the Gapps, factory reset, wipe cache and wipe dalvik cache then reboot. After you get the device booted, you can delete the Gapps file then download a smaller package and put it in your phone's internal storage then boot back into recovery and select the "Install" option, at this point, you already have the ROM installed so no need to flash it again, but you do need to flash the new Gapps file, then factory reset, wipe cache and wipe dalvik cache.
Do you see how important it is to factory reset, wipe cache and wipe dalvik cache every time you flash? It is a vital step.

Hey thanks for all these but my device is using cwm right now so can you pls rewrite the instructions for me?
Also i cant finish the setup with all these popups so theres no way i can load files into it.
And yeah i guess i didnt wipe data or caches away after i finished flashing the files.
Thank you so much.
