Black screen o Death part II

I posted this herehttp://code.google.com/p/cyanogenmod/issues/detail?id=329
This has been happening for me for a few cyan updates now, and also on the HTC 1.6
image currently
the g1 was "charged", when i got home i took it off the charger and cranked up all
the bells and whistles. within 5 minutes the g1 goes black except for the keys for a
moment and then they go dead as well. no reboot. just goes dead. when i do reboot it
it sometimes wont go throught the whole reboot without shutting back down. does not
happen when it is on the charger. really hard to calibrate the battery when your g1
wont stay on without the charger and when it is it says its charged! i would post it
on the bug tracker, but i can't tell if it's my battery or the rom
and i'm running the death spl 8g card, cyan recovery and newest update, with only a
fat32 and no ext or swap
an update.. maybe check into the device staying awake. seems like with everything
running(gps, 3g, blutooth, etc) and with the phone sleeping, it doesn't crash, but if
the settings to never timeout the screen are active and you leave it on, it crashes
within a few minutes.

you should have an ext partition (the swap is recommended but not required). I only say you should get the EXT because the problem may come when all your apps are in the fat32 drive... it doesn't unmount correctly when you shut down or reboot your phone so your apps / partition sometimes get messed up... this MIGHT be why you get the black screen because it's corrupting the running processes (that are running from the fat32 (apps2SD)) when you reboot the phone(or mount the drive on the computer through usb) while they're being used.... repartition your card to include a EXT3 partition and reinstall the rom... let me know if that works. Post #69 hope this post helps, lol

i have had an ext2 ext3, swap, no swap, all with fresh partitions.

awww so i wasted post #69 lol... Did you keep the 1.6 HTC rom? or did you upgrade it to CM 4.2.3.1? Maybe it's the HTC rom that's the issue? install the 1.6 htc and move to cm 4.2.3.1 (you can go straight from htc1.6 to 4.2.3.1, just follow the instructions) and start with fresh fat/ext/swap partitions... i personally use 100mb for swap (just in case i try a rom that uses more than 32mb by default i don't have to repartition)
edit: sorry, just noticed you said it's been happening on a few CM builds already....
try this: make sure you have CM1.4 recovery, new radio and new spl... new partitions (fat/ext3/swap) install the HTC1.6 rom, as soon as it reboots into recovery install the 4.2.3.1CM update. reboot phone and boot everything up as normal....
If it doesn't work after 100% fresh install like that... then maybe it's just a phone issue?

thanks for your help, but I originally formatted and followed cyan's instructions for his newest legal rom. i had this problem still, and then tried to fresh install the stock 1.6 from htc, and still. i think it's an aosp thing. i have had everything running( 3g gps sync blutooth ) for a couple of hours while the phone has been asleep and i can wake it. but if i turn the screen on, its only a matter of minutes before a crash. it's all posted on the cyanmod code.google site http://code.google.com/p/cyanogenmod/issues/detail?id=329

Is anyone running Advanced Task Manager, someone typed in market that it was doing he black screen of death so I uninstalled it and reinstalled it and it was still acting weird so I unchecked "show Auto-End notification" and it seems to be working a lot better no black screen o death

i used to get the blackscreens. i dont get them anymore. turning off compatibility mode in spare parts helped. try that. untick and reboot.

it has nothing to do with the SPL. try the spare parts trick and see if that helps. even if it slows it down to once every 3-4 days would be an improvement.

wipe out your sdcard's ext partitions (not the fat32), and do a full wipe. reinstall the rom, get spare parts, untick compatibility mode, reboot, and then observe.

[Q] Freeze at booting (FroyoBread/GingerDX)

Hello dear xda-community,
I'm new to community OS, but I gave it a try. Rooted, xRecovery installed, App2SD - everything no problem. But I have huge problems with getting FroyoBread to work.
At first I downloaded the latest version of GingerDX, installed it (custom zip) via xRecovery and when I'm now booting, it always shows the animation of that skateboarding blue Drood (don't know the name of it, sorry). So after 5 minutes I took the Akku out and tried it again: same :/
So I thought to myself: Why not FroyoBread? It has the features you need and also a nice look. So I tried this - unfortunately the same. The animation continues until the orange Drood (sorry again) and then it freezes. In both cases I let it load for an estimated 15 minutes, maybe it takes longer at the first run - I was wrong :>
I did several full wipes, I don't know what else to do. I set up my old backup to be able to keep using it, but with FroyoBread it would be much better, wouldn't it?
Excuse my bad English, I'm German and heard of you guys being pros at you area, so I decided to demand to the highest
Sincerely,
anfyd

Indeed strange.. Can you check your baseband and see if it ends in 15?
Sent from my E15i using XDA App

First thank you for your reply.
Jup, my baseband version ends with 15, kernel is also up to date. I updated everything with SEUS. Are there maybe other ways to install FroyoBread?
Sincerely,
anfyd

Not very sure why this happened, but I suggest you do the following.
Flash back to stock rom.
Root it again.
Install xRecovery.
Boot into xRecovery.
Backup your phone.
Perform a full wipe.
Wipe cache.
Wipe dalvik-cache
Install Froyobread/GingerDX using the install custom zip method.
Perform a full wipe again.
Wipe cache again.
Wipe dalvik-cache again.
Reboot your phone.
Pray for the best (not needed).
Hope this worked!
Cheers ,
SpyderX

For some reason it's working now but sometimes it boots forever - after taking out the akku and try it again, everything works smooth.
Thanks a lot to you for replying to me

Happening to me
This is happening to me, does never start

[Q] Samsung Galaxy S GT-i9000 freezes after around 30 seconds from reboot.

Hello everyone, thanks for taking your time and reading this.
I've owned a Samsung Galaxy S GT-i9000 for about two years now. This phone is not my primary phone, as I just use it as a secondary phone for different apps/backup, most of the times the phone is turned off.
But a few days ago, I turned the phone on, and once the homescreen had loaded, around 20-30 seconds later, the phone will freeze, and there's nothing else you can do other than take the battery out to turn it off.
A few details about the phone: the phone has never been flashed, and the OS has never been touched. It's basically at stock, but the only thing I remember is updating the official firmware through the Samsung link in the settings. The phone has never been modded, and that's what bugs me the most. (I've never had experience with 'modding' phones with custom ROMS and such)
So, after sitting at home all day looking for a fix, I couldn't find anyone else in my situation. There are a few similar situations, but I am yet to find something that replicates my problem exactly.
I've also tried rebooting the phone in many different ways, for example, taking out the memory card, then taking out the sim card, then taking them both out completely.
That's when I found a link which gave me information on how to factory reset the device. Since nothing else was working, I decided to go for it.
I held the VOLUME UP button + the HOME button, and hit the power button and got the menu up.
The menu works fine, I was flicking through the options for 10 whole minutes just to check if it freezes or not, and it works perfectly fine.
So then I factory reset the phone, wiped the system cache, and I also formatted the internal SD card.
Still, the problem persists. This time, the phone will reboot for a little while longer, since I expect the system files are getting set up, then it asks for the language, and before I can hit English, it freezes, and the screen stays like that until the battery is dead. All the hardware buttons don't do anything, it's basically fully dead with the screen still on the OS menu.
I was wondering if anyone knows what I should do?
I can provide more information if needed, and I can even upload a video to YouTube if you want a better aspect of the problem.
Any help is appreciated, thanks.

is it i9000 or 9100?

Ah, sorry, got the title completely messed up there.
Yes it's the GT-i9000 and I think it had Froyo 2.2.1, forgot to include that in the main text.

Could try Rooting the phone and wiping all options in Recovery and Reboot
or
Could be that something maybe corrupted which is halting the system
Upload a video so that we can offer better advice
Which Rom / Firmware are you using?
Last option.
Would Recommend Downloading Rom (whichever you choose) and go from there....

Major UPDATE:
Okay, so after sticking at it the whole day and trying to get a better understanding of this situation, I've managed to work around the problem slightly. It's not fixed yet, though.
So after the screen had frozen for the (insert number here)th time, the battery was starting to go empty, so I stuck it on charge, but I forgot that I had left the frozen screen on (currently frozen on the 'Language Select' set up menu).
After about 20 minutes, the phone vibrated and a little message popped up, and it said that 'the process Soundhound.com.xxx.xxx was force closed', or something along the lines. I can't remember fully because it popped up for only around 4 seconds and disappeared.
As soon as I saw that, I quickly went to the application settings and deleted all of the soundhound cache/data and then removed the app completely. After that I thought it was fixed for sure, so I was messing around with the phone and using different apps to see if it freezes again, and it didn't.
But I had to restart the phone to see if the freeze issues happened again, and yep, it was there again, this time the same as the first issue, where it used to freeze up in the home screen. AND, I let it sit on the frozen screen for 15 minutes and it was that SAME soundhound app that got force closed, so once it got out of the frozen state, I quickly went to the application settings and the app was still there, it was like I didn't even delete it?
This leads to my new problem, the so called 'hard factory wipe/reset' doesn't actually reset EVERYTHING. As seen in my other post: http://forum.xda-developers.com/showthread.php?t=2305825
Now I'm completely confused as to what I should do.
I've pretty much tried everything, and i'm sure a FULL hard reset where EVERYTHING gets wiped out might just fix it? The thing is though, I don't know how? I've been trying to fix this phone for about 7 hours straight now.

My opinion Flash a Stock Rom or what ever you wish and then Root it...
If selling it just dont bother with Rooting it.
As you say you have been at it for Several hours and flashing takes less than an hour even for a newbie if following the procedure correctly
As going by what you say it seems that files are messed up on the phone and better to start fresh

Is there a legit way to flash it, maybe through Samsungs website? I don't want to mess around with custom files, as I would like to keep everything clean.
Oh, and also, I just went through the media files and found some of my old pictures too. So for some reason, the 'format internal SD' option in the recovery menu isn't working.
If I flash it, will I have to flash it to Froyo 2.2.1 which it is currently in right now?
Here's information I found on the 'About phone' menu:
Kernel version:
2.6.32.9
[email protected] # 1
Build number:
FROYO.XXJPY
Baseband version:
i9000XXJPY
Thanks for all the help so far.

Legit way your on XDA!
Flash a Stock 2.3.6 (Clean) which is the same as Samsung Site its in my How to Guide if you wish to follow it
Its the exact same Rom just not on there Site

Thanks.
Briefly read your guide, and it's all mind boggling to a newbie like me :silly: lol
I might just have to flash it, because this problem is getting a little bit annoying now.
Which parts of your guide should I follow exactly? And shouldn't I be sticking Froyo 2.2.1 back in? Won't a newer firmware (such as the 2.3.6) make the phone slower/drain more battery than usual?
Oh and one last thing, what's the difference between rooting and flashing a phone? Cheers.

Rooting briefly means :
Giving yourself root access to system files and the ability to change things that normally are marked read only
This allows you to change all kinds of things that normally you wouldn't be able to
Flashing : Erm.. Flashing a new Rom on your Phone or the process of over-writing your internal memory
2.3.6 will be ok for you if you wish to stay just Stock on your phone.
Plus the fact if you wish to move to another Rom later on its just a matter of Rooting the Phone and installing the Custom Rom
Just follow guide from the : HOW TO GUIDE : TUTORIAL TO FLASH 2.3.6 JVU + ROOT BEFORE INSTALLING CUSTOM ROM
and you will be ok.

So the 2.3.6 Firmware you provide, is that known a 'custom firmware'?
I've been searching for YouTube videos with people explaining how to flash, but all the videos sound like they're speaking about some rocket science sh** lol
Now I'm super confused, some guy on YouTube is flashing to 2.3.6 JVT while you're doing JVU, I don't even know what that means haha
I just don't want to brick the phone and make it completely dead, that's why I'm just making sure I understand the basics before I go ahead with it, sorry if I'm starting to sound annoying lol

You wont brick it if you follow it correctly...
2.3.6 JVU is the basis for all custom roms been flashed unless stated otherwise by Rom Developers.
As its basically a stock 2.3.6 then when you want to flash another Rom its just a matter of Rooting the 2.3.6

Ah, okay.
Well, I'm in the process of downloading your files, THANKS for ALL the help you've given so far, sir!
I'll flash once all the files are downloaded. By the way, does 2.3.6 have Google Play store, and not the old Andropid Market?
I hope I can get this done before I head off to sleep in a few hours, been a very long day haha
I'll let you know of the results, cheers and have a good day sir.

No problem hope it all works out for you :good:
Not sure if Google Play is on it as its 2.3.6 Stock ...just upgrade it if possible

I was just wondering, did you say I should root or not? As rooting it seems like a bit of a hassle? Plus, it says that I should install a custom rom zip file if I decide to root it, but I don't have one? I am using your 2.3.6 which was in your Odin Files download link, right?
So if I root, what do I do exactly?

Exactly the same way before I flashed it :crying: :crying: lol
I actually feel like crying right now haha, I think the phone may be completely dead? Something is seriously corrupt with it I'm guessing?
I've never dropped it, or accidentally dropped liquid on it or anything like that.
I have absolutely no idea what to do now. Sigh.

You could try reverting back to 4.3 then update to 4.4.2 by installing a custom rom.

By any chance your extreme lag also affects the audio performances? I and a friend of mine had in the same period (for 2 weeks) EXTREME lag, signal lost on mobile network. The lag was so powerful that even music was interrupted. The only way to get rid of this was rebooting the tablet.
The most awkward part is that the bug persisted over ANY KIND OF ROM/KERNEL. Even the official one from Google Developers (any android version).
Best part: It was fixed by itself. Lags started to be increasingly rare and at some point they stopped.
I tried to catch some logs...at the moment of failure, just once they pointed me to some lines in the source code...so I quit trying to figure it out what happens..

I had the same problem, I solved it installing SlimKat, but probably you can solve it with any custom rom, I tried many times to restore 4.4.2 but always the same, only installing custom roms seem to solve it...
I remember it, is like a nightmare to me, turn the tablet On and let it 5 minutes before open any app, open Google Play and see how it lags, installing apps always causing freezing... It remembers me my Windows XP years...
At the beginning i let it thinking it will solve itself, haha, after months I was about to broke it with a stone

If you want to keep the official rom you can just try to reflash 4.4.2 wiping everything, just copy to PC the files you want to keep and after flashing copy again to tablet, i would recommend you to copy only important data, not everything, and specially not copy the folders with strange names that you dont know what they are

Before flashing anything try to restore the tablet, copy all your stuff to PC and format it by going to settings / backup and reset / factory data reset and checking to wipe all on internal memory/sdcard
It will wipe all your data, apps and everything, so be sure that you dont forget anything to be copied to pc.
Maybe it solve the problem without flashing
About root and flashing:
You dont need it, but you can root it if you want after flashing,
I dont know how much you know about flashing and all that, so Im gonna make you an quickly tutorial
Basically all you need is:
Nexus root toolkit from here: www.wugfresh.com/nrt/
4.4.2 firmware (can be downloaded directly from the Nexus Root Toolkit)
And be sure that you have copied to PC everything you dont want to be deleted, you can just copy all to PC and after flashing copy to tablet only what you want...
On tablet turn on USB debugging, on developer options (To unlock it go to settings /about tablet /build number and click it many times until it says "you are now a developer", then go back and you will see it)
When its done follow the Nexus Root Toolkit instructions to "flash stock + unroot" (by clicking a button with that text) you should select Android 4.4.2 (KOT49H) and check the option "automatically download"(dont remember what the option says exactly)
And the tool will download it and tell you when you have to do something. Just dont disconnect the tablet until the tool ends its job
Maybe you should install some drivers if you get an error message like "device not found"
If you want to know more about insalling drivers, you get any problem or something else just tell me, but maybe im gonna make you wait because tomorrow is my birthday and I wont be checking it for few hours.

Before flashing anything try to restore the tablet, copy all your stuff to PC and format it by going to settings / backup and reset / factory data reset and checking to wipe all on internal memory/sdcard
It will wipe all your data, apps and everything, so be sure that you dont forget anything to be copied to pc.
Maybe it solve the problem without flashing
About root and flashing:
You dont need it, but you can root it if you want after flashing,
I dont know how much you know about flashing and all that, so Im gonna make you an quickly tutorial
Basically all you need is:
Nexus root toolkit from here: www.wugfresh.com/nrt/
4.4.2 firmware (can be downloaded directly from the Nexus Root Toolkit)
And be sure that you have copied to PC everything you dont want to be deleted, you can just copy all to PC and after flashing copy to tablet only what you want...
On tablet turn on USB debugging, on developer options (To unlock it go to settings /about tablet /build number and click it many times until it says "you are now a developer", then go back and you will see it)
When its done follow the Nexus Root Toolkit instructions to "flash stock + unroot" (by clicking a button with that text) you should select Android 4.4.2 (KOT49H) and check the option "automatically download"(dont remember what the option says exactly)
And the tool will download it and tell you when you have to do something. Just dont disconnect the tablet until the tool ends its job
Maybe you should install some drivers if you get an error message like "device not found"

I tried to restore the tablet and that didn't worked (look at the first post).
I will try the 2º option, thank you !!

Ya the tablet is extremely slow, and freezes sometimes for some seconds!
What do you mean with "rebooting the tablet"? Factory Reset on the original recovery menu?
Thanks.

No...just a simple restart. As I stated, I tried different resets and flashes and everything and nothing worked...

Be careful about "Returning to stock" method as I think Google broke their "flash-all.bat" from the arcvive of Android 4.4. Flash every file by your hand. I used that idiotic flash-all on any android version, but on 4.4 it completely broke my motherboard by flashing wrong boot.img.

Okay, I was no sure that you also format "SD card" factory reset do not delete user data/sd card on some devices and Im not sure if in N7 you have to check the option
Try the 2° option but take a look at this comment:

If thats true then try to flash 4.3 and install 4.4.2 by OTA, just select 4.3 instead 4.4.2 when you are about to flashing

Ok,
I flashed the nexus 7 2012 directly to the factory 4.4.2 using the nexus root toolkit, and everything is working fine without problems, at least for now.
The tablet isn't giving exchange errors, and doesn't hang everytime, but I only used it for some minutes, lets see how it works after some days/intensive usage.
Anyway, as I said, I flashed to 4.4.2 directly using the toolkit, and it worked without any problem
Thank You!

Can't turn off wifi toggle

has any one been having any trouble with their wifi on their nexus 6, randomly the wifi toggle will stop working the toggle will be off and it still says "Turning Wi-Fi on..." i've booted into recovery and cleared cache and rebooted the phone and it worked the first time and it's been acting up again and this time clearing the cache isn't working does anyone else have any ideas without doing a factory reset.

maybe try just flashing the system img, then wipe cache's again before booting. if that doesnt work, its may be time for the dreaded fdr.

I've never been into flashing system img & fdr? It's just sad because I had the same issue before also losing signal with my device. Til I got a replacement and the replacement device is starting to act up also.

my only other suggestion would be to re-flash. you could try just the system partition, but if it were me i would just go all in for full clean flash.
im sure Simms will get on me for saying so, but you can just grab wugs toolkit and be done in 20min or so.

I've never flashed before i know from what i hear its really easy for Nexus devices. but i'm just curious what would of caused this like from my first N6 since December and it acts up now in Sept and having the replacement N6 acting up the same way.

Is it rooted with mods or completely stock? If stock, try deleting the saved wireless networks..

these random issues usually come from a corrupt file, either by an update or some other means. its hard to impossible to pinpoint the cause usually.
if you never flashed before, its best to read up on it a bit first. wugs walks you through the steps, from downloading the files, and drivers, to the flashing. its not foolproof, but if you follow the lead of the script, its not hard to figure out.

well i have before but that was so long ago and that was for my MyTouch and HTC Sensation but that was years ago. Now I know things are easier but I've never really been into flashing and the only reason I did back then was for updates and different version of Sense UI but since I've been using Nexus Devices I didn't have a need or desire to actually flash. Pretty much I'm a NOOB! :laugh:
but I don't see why wouldn't a factory reset fix it. even if it was temp.

a factory reset only deletes data, it does not restore any of the file system to its original state.

clearing the cache is always a good idea, i think i suggested that earlier.
i dont know how to explain well what cache is exactly, its not part of the file system, its more like temp data storage i believe.

def of cache from google
"In cell phones and networks, a cache usually refers to a memory storage area in the phone or network that stores copies of information that is likely to be needed in the near future, so it can be accessed faster."
i dont know how to flash with a chrome book, if possible. sorry

thats pretty consistent with what i said earlier. these type of issues frequently arise after updates. files dont update exactly right and something gets corrupted.

i decided to call T-Moblie and talk to them they told me to take it to a store and get it dianogsed and they will call to get it replaced since it is the 64GB and stores don't have it.... I just want the Wi-Fi to work even though i don't use it all the time but still.
