Check the md5sum of your "Official" 4.23 bootloader if it isn't THIS:

Those two post will explain in further details.

Let me know if you are still having issues. As long as your device is detected by ADB and fastboot it should be fairly easy to recover...

Also, are you still trying to do F2FS or Custom Kernels at this point OR just get back to Working Stock ??
[Nexus 7 Q&A, Help & Troubleshooting] Narwhal73:
I'm not sure what F2FS is, so I'm pretty sure I wasn't trying to do that. I'm just trying to get an actual bootable OS back onto the tablet. Stock Lollipop is preferable to anything else right now and I'll worry about customising it again at a later date...

I was unaware that Google/ASUS fudged up the bootloader images for the last few major releases (that would explain my inability to flash 4.23 to the device), so I'll try the instructions in the threads you've pointed me to when I get a chance. Thanks!

I'll report back with any successes or failures at some point next week; I have exams to study for in the meantime... :eek:

Hi dude, you can Try to install Firmware stock 4.2.2 and after upgrade it using ota. My friend resolved same problem in this way.

[Nexus 7 Q&A, Help & Troubleshooting] Narwhal73:
Okay, so I found time to try to fix this thing tonight. The bootloader from KRT16S flashed fine, so my N7 is once again running bootloader version 4.23. The issue with flashing the system.img persists however.

The error I get is:

writing 'system'...
FAILED (remote: (FileWriteFailed))
finished. total time: 93.175s

What is so frustrating about this is that a "write failed" error message isn't very descriptive. A write could fail for any number of reasons. Is there a way I can enable more verbose error output in fastboot?

The only thing that I can think of pinning this on is an improperly sized partition. Unless there is something someone else can think of, could someone point me to where I can get the stock partition layout, and how I can repartition the device?

EDIT: not sure of the relevance, but I have just noticed that as soon as fastboot begins sending the image for writing, the bootloader on the device freezes up. Like I can't scroll through the options, not see any live text on the screen. Same goes for userdata.img.

EDIT: Here's all the bootloader variables (S/N changed in this post for privacy), can someone make sense of the partitions? What's with the hexadecimal?:

$ fastboot getvar all

[Nexus 7 Q&A, Help & Troubleshooting] Narwhal73:
Bumping this again because I'm still having issues, anyone have any ideas about how I could go about getting my N7 back to working stock? It's recognisable by Fastboot, and I can get a working ADB connection through PhilZ recovery, but apart from that I can't do anything. It's a nice tablet and I'd like to get it back to a usable state. :eek:

So I am very new to this kind of stuff, I just bought a S5 and installed cyanogenmod, My question is can I use the Keyguard.apk to add the fingerprint scanner back?

No the code for the fingerprint scanner is in the framework.

Ok thanks, I assumed if it was that easy I would have found a post about it, but figured it wouldn't hurt to ask. Thanks for the info.
[T-Mobile Samsung Galaxy S 5] elesbb:
Yeah it would take forever (to the point it's not even worth it) to go through the millions of smali code to find everything it uses. Not to mention the settings app will need to be changed too. Your better off just using a stock based ROM. Plus with xposed stock ROMs can actually be really nice.
[G3 Q&A, Help & Troubleshooting] scy1192:
Does anyone know if it'll be possible to have v3 of the Camera HAL implemented so we can take advantage of all the cool camera improvements? We know from the Nexus 5 that it's possible for an older device to be upgraded, but does this need to come from LG (which seems unlikely at this point) or will generic Sony Exmor 135 firmware be able to be hacked in? Unfortunately I don't even know where to start to see if it's possible, so I figure I'd ask you fine folks.

Hi everybody,

So I have an HTC One M7 running Google Play Edition Rom and my touch screen stopped working. Now, this isn't the first time it has happened but it is the first time it's happened on this rom. I was previously running Android Revolution HD and when my touch screen stopped working, I would hard reset by pressing and holding the power and volume down button until the buttons started blinking for around 10 seconds, and then the phone would restart. However, I can't hard reset my phone anymore. I tried holding the power and volume down button down, but after a full minute, the phone still didn't restart; it was just the capacitive buttons flashing. I tried every combination of holding down buttons but it still doesn't work. What should I do? Any help would be appreciated.
[One (M7) Q&A, Help & Troubleshooting] otij:
use an OTG cable adapter and plug a mouse ;

go to settings backup and reset : reset phone .

if this is what you want to do.

kinda only way to reboot if you stuck .

or download a rebooter apk
[Samsung Gear VR] Thor:
Just thought I would throw up a thread regarding the gear vr and a custom rom on the note 4.

A few things to note.

I'm using it on my international N910f in Ireland with zero issues

Custom Rom has no issues (Dr Ketan v2)

My DPI is set to 480 and all of the Oculus apps work perfectly without the need of changing their own DPI's in app settings. (I got the feeling it even looked better, but could have been in my head).

Also, I noticed the Oculus Cinema is now picking up all the content on my My Micro SD card. Not sure if was doing it from the start as I was temporarily using the card the gear vr came with. Can make searching for specific videos annoying if you record a lot of videos yourself.
[Samsung Gear VR] Powerslash:
On the setup process did you create a new oculus account or did you already have one. And when you made a new one did you chose ireland as your country or USA?
[Samsung Gear VR] Thor:
I made a new account and I picked Ireland.
[Samsung Gear VR] Powerslash:
Ok thanks, i wasn't sure if there is a region lock on the store and will allow only US users.
[Samsung Gear VR] richlin71:
I'm also using a custom ROM (FireKatN4) just fine, although I had to flash a new kernel (N4 TMO AEL Kernel) to get it to work. Info is in the XDA FireKat thread: http://xdaforums.com/note-4-tmobile/development/firekatn4v1-4-4-4-tw-anj7-extremely-t2916463

Has anyone tried using the VR on lollipop or cm12?
[Samsung Gear VR] ceo.mtcl:
Which kernel are you talking about? I can't find that...
[Samsung Gear VR] InsuredApple:
I am confused. So when you guys put the Note 4 in the Samsung Gear VR... it does not prompt for a carrier software upgrade?
[Samsung Gear VR] ceo.mtcl:
I have a tmobile note 4. When I plug it in, it does not ask for any software upgrade. However, I can't use any custom with gear VR. I have to flash the stock nk4 Odin tar to get it working.
[Samsung Gear VR] InsuredApple:
Where can I get this tar file you speak off?

Thank you sir.
[Samsung Gear VR] ceo.mtcl:
Can you please confirm that you have a T-Mobile note 4? If not then you can mess up your phone.
[Samsung Gear VR] jarazmek:
So if I am reading correctly the VR will work on custom roms if the kernel is compliant? I was running stock rooted, wanted to get rid of the lag in the system and went over to SuperStockRom and now after loading the Gear VR software all I get is a blue screen and after 5 seconds it goes to the home screen but with no movements or menus... any ideas?
[Samsung Gear VR] pyr0path:
i'm loving rooted stock at the moment while i use my VR. all that you have to do is flash the latest(or which ever one you prefer) ael kernel in twrp/cwm over whatever rom you are using. no need to setup anything further than that. here's the link for the ael kernel thread http://xdaforums.com/note-4-tmobile/orig-development/30-november-2014-n4-ael-kernel-t2961240
[Samsung Gear VR] chakra:
No because we are using a coustom Rom thats already upgraded
[Samsung Gear VR] Thor:
As long as it's a custom rom based on NK4 or later, then it should work perfectly fine. That being said, some people may be using custom kernels based on older versions, which may causes issues.
[Samsung Gear VR] jarazmek:
Thanks, I'll give it a shot.
[Samsung Gear VR] haxyn:
Hi Thor, I also have SM-N910F

What ROM should I flash to make VR work?
[Samsung Gear VR] Thor:
You can just flash the generic firmware for the Note 4. It's on Sammobile.com. Or I can PM you a link to one I uploaded(will download faster)
[Samsung Gear VR] haxyn:
You mean I can just download SM-N910T and upload to the phone via Odin without root?

[Samsung Gear VR] Rayan:
My setup:

T-Mobile Galaxy Note 4

Gear VR

FireKat V9

AEL Kernel V7.2

No issues whatsoever!

The Gear VR is so freaking underrated when in fact is the Samsung Galaxy Note 4 "Killer App"!

I recognize I had my doubts about this, but now that I'm using it, there's simply no way to describe it!

SIMPLY AWESOME!

Im on my phone right now, but you can do some editing of colors and images, which isnt too hard. You have to find the .edj files, use edje_decc to decompile them, you will end up with a edc file and a build.sh file to recompile.

Pretty much what i've found is we will not see custom watch faces on the lockscreen, till Samsung allows us. I have figured out some ways to customize the default digital time lock screen.

If you change any of the api permissions in the xml files make sure to update smack as it will reject it.

Ive been able to pull packages using Sdb. For instance I pulled, /usr/apps/com.samsung.w-contacts2, which has some images that are decompiled, like home screen icons. So I havent actually decompiled anything. Sdb pulls all of the folders and signatures. If I wanted to edit a couple of images then push it back to my watch, how would that be done?

For those that do not know what the directory structure looks like, as I asked in my previous post, download DiskInternals Linux viewer

http://www.diskinternals.com/linux-reader/ Open the program and browse to rootfs.img file of Cipherswitch and mount the image. It allows you to view the files on the image.

What exactly is Flora? I thought all linux distros were open source. Isnt Tizen based on Linux?

---------- Post added at 06:05 PM ---------- Previous post was at 05:57 PM ----------

@ooms ya, when I pulled that particular app, it came in folders. Now that I think about it, its just a usr folder. I was hoping to theme the whole os.
[Samsung Gear S] ooms:
So digging around, in the contact app folder in res/edje you have 4 .edj files you will need to decompile using edje_decc and edit then recompile.

Flora = http://floralicense.org/

So all the system apps in the source are already pre-compiled, there are some .h files that refer to the apps and "distributor" level api's but no .c files.

So till they release the source can't do too much custom stuff. Kind of like how they release the source of the Note boot loader but it's worthless because it's locked with proprietary information that they won't release.

Just the other way around.

Following the Gear S thread... quick question for another device...

[MENTION=283412]Cipher[/MENTION],

First of all, great thread, I've been following only for a couple hours and I've read every post from the last month or so (starting when it was posted by someone else and taken over by you in this thread) I'm excited to get started on rooting my Gear S.

On another note altogether though, I was wondering if you knew of a resource where I could get info on rooting the Galaxy S4, AND Galaxy S4 active. I'm currently trying to root both to work with DoCoMo here in Japan and I've read some success stories but have had no luck myself. I'm fairly versed in Linux, Android, and some rooting experience with other devices but I can't seem to get these ones to cooperate.

I've tried the "TowelRoot" and the other vairiant from Geohot with no success. I just finished my 7th attempt with the Kingo root, again, no success. Both Galaxy phones are running 4.4.2. One is the "active" variant, and one is straight up S4. I'm ultimately trying to get all my devices to work on the DoCoMo network here in Japan and I know I can do it with the right resources. Any help you can provide is GREATLY appreciated. Please feel free to email me if you have the time. Keep in mind we are 15 hours or so ahead of you guys so it may take me a minute to respond. Thanks again, I look forward to hearing from you.

Hello all...i have a question in putting in custom notification tones. I modified the script from the lollipop theme to push my own notification tone. But it doesnt work on the watch. Any advice pls.
[Samsung Gear S] cipherswitch:
the theme install scripts is not the way to do it, you should already have the folder structure after rooting, drop the already converted .ogg file into the appropriate folder, then run the update script.

Update scripts

[Samsung Gear S] bravo-_-:
you can Achieve root access once you download cipherswitch firmware. for the iphone 6 its going to be limited to some notifications it gets, it's good that you can connect any phone with the gear s..
[Samsung Gear S] cipherswitch:
for the themes its simple, copy files to pc -> turn on root -> change file system to re-writable -> change folder permissions for affected folders-> push files from pc-> change back to Read Only file system -> wait -> reboot.

for alerts and stuff, its a bash script, basically ur not writing directly to those folders, you put your content in the visible folders and then the script moves it where it has to go.
[Samsung Gear S] skyred5:
Icic...thats what i tot so too. Which is why I modify it to push the ringtones in. I removed all files related to the themes and just put in the ringtone meant for the notification.
[Samsung Gear S] cipherswitch:
thats just a harder way to do it..... honestly, I just use the Tizen SDK for my personal watch, with root you can get into the nitty gritty of the watch and just drag+drop+delete right from the directories.

Good evening!

Does anyone have any information on how to root (preferably easily) Sprint's fancy watch? I'm seeing Att/TMO, but no Sprint or VZW. What's the deal? Cause it's CDMA vs. GSM? I just want root! Is that so much to ask? ;)

Cypherswitch,

I rooted to your specifications and it was successful.....however, because I have the Sprint variant, I do not have a sim card. Tmobile does. And now its got tmobile firmware that is not letting be connect to my data because there is no sim card in it. I thought I read through and saw it was kosher....maybe I did something wrong? Any ideas. Thanks in advance, my friend.

Jimmy
[Samsung Gear S] cipherswitch:
Thank you for reading through the thread.

There is no root for the Sprint or Verizon variant. There just isn't. Also, there is no equivalent firmware for your specific model that doesn't require a sim card. The bad news, I have no fix in any shape or form for what you did as I don't have access to the stock firmware ( If I did, you would have root already) . Samsung kies is defective and can't re-initialize the watches properly if at all. I believe the last member that did what you did ended up going through for a warranty repair directly with Samsung.
[Samsung Gear S] Resq176:
Can you PM me, Cypherswitch? I dont want help fixing what I have done, I just need clarification on one thing.
