[Q] CM9 Alpha 1, no boot animation

After upgrading CM9 Alpha 0.6 to Alpha 1, the boot animation does not appear anymore. I tried to replaced the bootanimation.zip file with a fullscreen one, but it still does not show up.
I also did a 'fix permission' from ClockWorkMod, but no change.
Everything else works fine. I will upgrade to Alpha 2 this weekend, but I don't think it will make a difference.

I'm assuming you can still enter CM9. If that's the case the boot animation disable function has probably been checked.

two things that can cause this.
1. wrong folder
if the bootanimation.zip is not flashable, then you have to copy it either to /data/local OR /system/media
change the permissions to rw-r--r--. If the system/media is not doing anything try the other.
2. if you did turn bootanimation off in previous built then it's possible it stayed turned off when you switched to newer alpha. there is a fix (this is shamelessly copied from somebody else on Rootzwiki)
maybe you still have the setting on ("persist.sys.nobootanimation"):

Works like a charm, got back my boot animation with your trick !

Any other ideas on how you can fix this issue? I am running Alpha 2 and have tried to install this Bios Boot both manually (with ES File Explorer) and flashing it: http://forum.xda-developers.com/showpost.php?p=21560233&postcount=1. The first time I tried to flash it, it failed. I think that may have messed something up.
I still get the black screen where the boot image used to be. I don't see the persist.sys.nobootanimation file when I go to /data/property.

XT890 unbrick (new firmware)

Many of XT890s with "Service required Code corrupt" are bricked and mine as well.
I've found out that there's a ancestor model - XT788 in China. And now we've all parts to reflash Medfield: ifwi (UEFI BIOS), osdnx (bootloader), osimage (kernel with fastboot). There's the last part to do, the fwdnx should be changed, but it has checksum and it should be recalculated. How to calculate dnx checksum?
Maybe you know somebody who knows!
He knows but I can't reach him.
http://www.linkedin.com/pub/tapan-shah/10/59a/39
View attachment dnx.zip

The algorithm is unknown still.
Could somebody make a dump of the first 500 Mb of the eMMC, please? (XT890)
Code:
su
busybox dd if=/dev/block/mmcblk0 of=/sdcard/dd.bin bs=500M count=1
After some time (10 minutes in the worst case), You'll find dd.bin file in /sdcard folder.
It operation will copy some specific to only your's device data. I'll not use it and will delete it after my analysis.

Sorry, my I is bricked, or I would.
So, by reading the "--help" message, "xfstk" is capable of flashing more then two files. I assume more then two files have to match/are the same/depend on each other to bootstrap Android. Why aren't more files being flashed? In my bricking experience, I tried flashing the ifwi and dnx files from the 4.0.4 that I was leaving, the 4.1.2 zip didn't have them in it so I tried others from a stock 4.1.2 rom and the original versions packaged with the xfstk. So which ones go with Mattlgroff's cwm Jelly Bean zip? What other files need to be flashed to un-corrupt the code? I don't see names that line up here.
The flashing utility works, we just need the right files to be flashed.

gilbertiddi0, things aren't so simple.
Motorola doesn't provide osdnx. I'm almost sure that it have never been developed for our model (XT890).
I still have no full dump of the first 500M.

Can you do that on an unrooted machine? If you can describe how to do that I will try. I am familiar with "dd" - just assumed you are needing the help of usb-debugging and busybox.

I went ahead and ran that command. This is a friends 890. As I hardbricked mine by opening the bootloader I am unwilling to unlock theirs

gilbertiddi0, Thank you.
As you see there is a mmcblk0. But only root has rights to read it.
Yours headset bricked with "Service required Code corrupt"? All others cases are debrickable.

Now that you mention it, yes in fact that is what happened. I never thought of it in quite those terms. The second time it got locked on the "bootloader unlocked" warning so I forced it off and turned it back on, I had always equated THAT as the important event: somehow it got stuck, in my haste I corrupted something by making it reload. Since it obviously couldn't get back to the "bootloader unlocked" screen even. I searched for quite awhile for that logo screen thinking that replacing that would allow it to cycle normally. Of course that isn't something you get with a new firmware like you're saying ...

I have the dump. The "pm" link doesn't include a file transfer, how do I get it to you?
I got another 890. It had Jelly Bean on it - it was a pain rooting (I used Matt's method of rooting - unlocked bootloader, flashed insecured boot - reinstalled boot) but I had to do it with "su-bin-3.1-x86" instead of the su file that came with it. Ohh, and replaced the "boot" that came with the unit. I knew you needed this dump and I am still hoping to fix that other unit.

And there's a hope to fix it still. Unfortunately Motorola have made it as hard as possible.
The fix process is the same for whole Z2xxx family and it suits to other devices. We're working with XT890 and Lenovo K900 now. But if anybody has a device on Atom SoC platform (Orange SanDiego, Lenovo K800, Lava Xolo X900 e.t.c) and wants to join - welcome.

HI!
Thanks guys for the help! i have a razr i and it is hard bricked, and there isn't nothing to do (the battery is over and the phone doesn't start) an option is change the motherboard with another and maybe the phone can start ? (sorry for my bad english but i am italian)

If you have no "Service required code corrupt" message - it have chance to be reflashed with standard tool.
And yes - if you'll change mainboard it will solve the problem, because it's like change the whole phone.

i had hard bricked my phone why i downgraded (not from jelly bean to ics , but i had downgraded with a fastboot ics from jelly bean and it was all ok, and when I flash with rsd a firmware ics the phone after 1 reboot gave me the "service required code corrupt" screen with the green led, i tried to revive the phone with the unbrick.zip but nothing outcome from the phone.. sometimes when i change the dnx and ifwi file the phone reboot with a dark screen but nothing..

Boot loop, problems with recovery

Hello,
I recently unlocked my bootloader and went to install a custom rom with Clockwork Recovery. It got stuck on the HTC boot screen (using an M7), and it would not move. I hard booted the device, and it corrupted my data.
Now, when going into CWM, the device reboots. I have tried reflashing CWM to no avail, so I then tried flashing TWRP. TWRP cannot mount any partition other than system. Problematically, I cannot get adb to recognize my device when in recovery (on multiple computers) but can get fastboot to detect it.
I cannot get a new image onto my phone via usb to fix it, and I cannot use the following guide (edit, cannot post links yet) to fix my corrupted data as a result. Also, I cannot get the device to show up as mountable storage in windows (I have yet to try Linux) to transfer files to it.
What are my options here?

Update:
I was able to update my "unknown" driver to the HTC diver in windows, and now can see my phone with adb devices.
So, I tried the data corruption fix by loading mkfs.ext4 to it and running :
/tmp/mkfs.ext4 -b 4096 -O ^huge_file,^dir_nlink,^ext_attr,^resize_inode,^extra_isize -m 0 /dev/block/mmcblk0p37
this completed, but now I still cant mount /data/ for some reason.
this is what I get:

Hey Wulf,
Sorry I'm still at work but this happened to me once as well. You wiped the OS completely from the phone and somehow corrupted the recovery.
I resolved it by relocking the bootloader and flashing a stock RUU. After it booted stock I unlocked the bootloader again reflashed the custom rom.

No CSC folder in stock MM?

In other ROMs I've edited an XML file in /system/csc to make some changes to the keyboard -- specifically, to display alternate symbols when you press-hold a key. I flashed stock MM tonight and noticed that this folder no longer exists.
I checked the Maximum OvrDriVE MM ROM and it does have this folder with the appropriate file. So what happened to the CSC stuff in stock?

Those are the stock ODIN flashable files. Once you flash it via ODIN you will see CSC folder on your phone under /system directory.

I've flashed the build a couple times now, same results. My procedure:
1. Ensure SuperSU zip is on external SD card
2. Boot TWRP recovery (currently 3.0.2 installed)
3. Wipe every partition except external SD
4. Boot the phone into download mode
5. Odin (3.0.9) the ROM to the phone
6. Odin TWRP back to the phone
7. Boot TWRP recovery
8. Flash SuperSU zip
9. Reboot and let settle for 15 minutes

Don't know if it would make any difference but you should be using Odin 3.11.1 with this latest EPG2 firmware. CSC related files reside in cache.img.ext4 , so it is possible that that particular file is not being flashed in your case.

I'm surprised the phone even works!

Hm, experiencing flash write failures. First time was about 15% finished. Second time seems about 95% finished.

Third flash completed. Before rebooting, I flashed TWRP. Then I booted TWRP and installed SuperSU. Booted normally and received the dreaded ddi: mmc_read failed message. Crap. Tried another flashing round, which also completed, and let it boot immediately. The Samsung recovery started (which I have never actually seen before) and ran through an installation cycle of something. After that, the phone booted and once again shows ddi:mmc_read failed. Is this thing kaput now?
----------
EDIT: I power cycled the phone and now it appears to be doing a normal first boot -- I'm staring at the T-Mobile splash and the status light is flickering blue/cyan. Wow!

Did you use the latest version of ODIN now? Also if the phone looks stuck on T-Mobile logo for longer than 30 mins, then remove the battery from the phone and try to boot again.

Yep, Odin 3.11.1 worked, but like I wrote before, it took three attempts. Weird.
BTW, not everyone agrees that the version of Odin was the actual problem:

Worked like a charm. Now I have wifi calling and secondary characters on my keyboard again!

You'll also notice that Bluetooth tethering is gone. T-Mobile likes to disable that for some reason. I imagine that buried in one of the CSC files is a line you could delete to restore Bluetooth tethering.

Memory limit caps the amount of memory zRAM can use. This is not something users must deeply understand to use this software. There's a config file: /data/adb/vr25/zram-swap-manager/config.txt (Android) or /etc/zram-swap-manager.conf (GNU/Linux). While the config can be edited with one of many programs, the usual way is with zsm -c [editor], editor being optional (falling back to vim | vi | nano).

Also while you are at it - if its ok with you wanted to ask you about fbind - is there anyway you figured out to modify selinux policy so it can run successfully on enforced mobs. I asked that in relevant thread. wondered if it updated. thx!

It almost seems like your kernel lacks [proper] zRAM support.
Share /dev/.vr25/zram-swap-manager/service.log (recreated on reboot).
Also while you are at it - if its ok with you wanted to ask you about fbind - is there anyway you figured out to modify selinux policy so it can run successfully on enforced mobs. I asked that in relevant thread. wondered if it updated. thx!

@sieger007, your kernel does not seem to support zRAM.
Which device is this?
Does /sys/class/zram-control/ exist?

Hi, can you please release a guide for how to do this? My goal is to keep (certain) apps running in the background. If I can't choose specific apps, I'd like to keep ALL apps running in the background unless I actively close them. It's pretty ridiculous not being able to use more than 1-2 apps at a time. I run adguard, accubattery, JamesDSP constantly. I also listen to music sometimes while also browsing or playing a light game. Browsing even requires the keyboard open sometimes to type. And don't even think about summoning the Google assistant or any voice typing because instead of opening as an overlay, it closes the background app and switches to GA as an active foreground app.
I'm using a Pixel 3 with PixelDust12 and sure, it only has 4 gigs of ram. But even stock behavior isn't this bad. And I have the highest amount of zram I can set through EX kernel manager. (yes my kernel supports it. I have the directory mentioned above with two files inside it)
But the more I mess with zram settings the worse it seems to get. At one point yesterday it got so bad I wasn't able to use even 1 foreground app without it crashing on me. Sometimes even pulling up multi-tasking is enough to make it all crash. I even switched to Pure browser because it has far lower foreground ram usage than Brave (more than half) and it was still not enough. I'm now in Via browser and it seems to be ok. But without anything running in the background. Even system keeps crashing on me. Dev ops shows 0 background processes and around 10% average ram usage. It's crazy. EX shows that zram keeps getting disabled.

Hasn't been updated in a year... Does this still work ?
