I hope K will be back in form after this week. :) I was checking for latest release on dropbox and when didn't see new kernel, I thought K is sick...

Meanwhile, waiting for my Moto G to arrive. I thought I would never ever buy a Moto again but Moto G has surprised me and Motorola is now transparent about their future. Besides, Punit Sony's team is working good. I just hoped they would have released the source code for the kernel.

Worst? Motorola released a quad-core beast for the price of a low end device. In my country, moto g costs ar$2000, while the competition (s3mini) cost more than ar$3000. Also is the only mid end device with 4.4

Moto x is also cheaper than samsung and sony's top line phones.

They now don't do promises that can't fulfill. Moto g was promised to only have 4.4 and my brother's g just got the ota a month ago.

To me, google's direction was a good thing. Hope lenovo won't ruin it.

One more feedback :)

I used CM9 (because of working bluetooth audio) with latest kernels (from 17.02, 22.02) for 3 weeks. In general it's ok - speed, apps, even battery life, but some issues annoying me:

- power button often doesn't wake device at first press;

- modem drops;

- camera focus: touch is always focuses wrong, autofocus is sometimes wrong;

- video focus: refocuses every 2-3 seconds (it was discussed, but i couldn't find a solution);

- slightly lagged bluetooth media volume adjusting.

[Atrix 4G Android Development] phoenixgfx:
I'm on 2/22 Kernel and it shows that there are 2 internal storage. One with 1.97GB and one with 10.70GB. Is that normal to be displayed like that because I never noticed it before.

I thought it should have 1 internal and 1 external...:confused:

Everything else (that I use) seems to work including Mobile Data.
[Atrix 4G Android Development] andresrivas:
That's right. The 1gb internal is actually the /data partition, where all apps go.

The other is what is mounted as sdcard, emmc, etc.

trying to update radio

I finally got around to trying to flash this radio -- to see if it would be better with regard to Google voice recognition as well as the reported speedups in GPS locking -- but haven't succeeded; I get a Status 7 error. I understand this happens when an assert that checks the phone model against that specified in the zip to be flashed. This is puzzling to me, as this is supposed to be a 38P radio for a U.S.A. Atrix, which is what I have. What could be going wrong?

I am running epinter's CM10.1-20131211, and the krystianp's kernel from 02_17. Model is MB860. Present baseband is N_01.77.37P. Recovery is CWM v5.0.2.7-atrix5.

Presumably I could clear the Status 7 error by disabling script asserts from within recovery, but this seems risky to me as there might be some other incompatibility. (e.g. do I need to revert to stock ROM to safely install?) The asserts are just the following:

assert(package_extract_file("bp.img", "/tmp/bp.img"));

assert(motorola.motoflash("/tmp/bp.img"));

It is at least the first one that is problematic: "assert failed: package-extract_file("bp.img", "/tmp/bp.img")".

This zip was created by [MENTION=2315905]ravilov[/MENTION], maybe he can comment?

UPDATE: I can see why the assert would fail, "/" is a Read-only file system so a directory /tmp can't be created. How does this script ever work? Only by disabling asserts? Safe to do? Seems like the flash needs to write to /tmp.

Feedback about some tests with rom atrics 20121114:

With rom atrics 20140107 neither kernel 201402 22, 23, 17, have mobile data connection but was very slow or none.

Tested kernel 20140205 with icsrom and the mobile connection was much, much better.

You dissable those assers, and the script won't do anything useful.

Afaik, in recovery / is rw and tmp should exist.

Tomorrow I can search my backups fir the att 38p radio I've flashed onto my intl atrix.

[Atrix 4G Android Development] ravilov:
Something is wrong with your recovery. I don't know about / but /tmp should exist and be writable. Literally all flashable ZIPs work the same way. Also, this radio ZIP has been used by dozens and nobody ever reported any problems so far.

Check the state of your recovery through adb. Like I said /tmp should exist and be writable. If this is not the case for you, remount / read-write and create/adjust your /tmp. Recovery runs entirely from RAM so no changes are permanent, if you mess sonething up just reboot back to recovery. Also check free space on /tmp - obviously there needs to be enough available for bp.img to fit in.

If everything else fails, you can always extract bp.img manually and flash it through fastboot.
[Atrix 4G Android Development] rhcohen:
So far not my experience. With terminal emulator I find / has no sub-directory tmp, and I cannot create one (even as su) because / is read only. And apparently recovery can't either.

I COULD use Root Explorer to mount / as R/W and then create /tmp, but I am unclear if the RW status would carry over to recovery. I guess I can go ahead and try.

I would like to know how people who have successfully upgraded to this radio on a CM ROM have managed to do so.

---------- Post added at 11:44 PM ---------- Previous post was at 11:04 PM ----------

Strange, I have had no problems flashing any number of ROMs and kernels using my current CWM. But looking at the asserts for example in one of krystianp's kernels, I do not see any reference to /tmp.

For now -- using Root Explorer I remounted / as RW and created a /tmp directory with same permissions as on my laptop (rwxrwxrwt). I will go ahead and try to flash with CWM. Given what you say it seems like I shouldn't need to do the above fix. What version of recovery do you use?

Oh -- what do you mean, "check free space on /tmp"? If I am just doing "mkdir" to create /tmp, what control do I have over that? I would think it has access to whatever free space is on the partition that / belongs to.
[Atrix 4G Android Development] ravilov:
Correction - All the flashable ZIPs that contain a flashable IMG deal with it in a similar way.

I didn't come up with the updater script for this ZIP, I used an existing radio ZIP and just modified the meta-information.

Feel free to try some other radio but I'm thinking if you're having issues with this radio ZIP you are likely to have issues with any other as well.

This is entirely pointless as the two root filesystems (main and recovery) have precisely nothing to do with each other.

recovery-RomRacer-blue-5.0.2.7-atrix5.img

Correct. I wasn't sure if /tmp in recovery is a plain directory or a mountpoint (for something like tmpfs). If it is a plain directory, then / is the containing filesystem and there needs to be enough space on that.
[Atrix 4G Android Development] rhcohen:
Kind of discouraging. Your messages suggest there is something deficient in the CWM I'm using, but before trying a radio I've had no trouble with CWM. I guess I could try RomRacer. But surely others have flashed with CWM. From what I've read RomRacer and vanilla CWM are supposed to be pretty much the same thing now (and we're talking about the same version number of CWM.)

I am wondering if there is a CWM setting that needs to be set to install a radio.

I wasn't aware of this notion of two root file systems. Is there a way to view the recovery file system? Via a file manager, or from a computer via adb? I can't find anything about this from a google search.

UPDATE: searching on RomRacer, I realize that is what I am running, though maybe a different color than yours. Looking on my laptop it appears the one installed was from a file "recovery-romracer-atrix5.0.2.7.img". I also see when running recovery that there is a Mounts and Storage menu, which gives me the option of mounting (I presume as R/W) /data, /osh, /pds, /system, /preinstall, /sd-ext, /sdcard, but no option to just mount /.
[Atrix 4G Android Development] ravilov:
Read my previous posts again.

Root filesystem, or /, is a RAM filesystem. It is temporary and only ever exists while the system is running. The only way to access it (to some degree) is to decompile the boot image and extract the ramdisk. This is why I suggested checking/modifying / through adb while the system is running.

This goes for both recovery and normal system.
[Atrix 4G Android Development] andresrivas:
Afaik, you are wrong. The / that recovery works on is not the / nor the /system you see on a fully booted rom. The flashing is independant of which rom you are currently using. I'm using CWM 5.0.2.X-atrix-X (I don't recall which numbers the x are refered to, but I know those aren't zeroes.).

BTW; I can't find the flashable zip for that radio...
[Atrix 4G Android Development] rhcohen:
And the answer is ..... the md5sum doesn't check for the radio zip. It did on my laptop but not after I sent it via bluetooth to the phone. So will re-download. It looks like it was the other part of the assert was the problem, something not checking with bp.img.
[Atrix 4G Android Development] ravilov:
Y'know... Instead of struggling with external services and their unreliable downloads (dropbox, gdrive, various filesharing services), you could've simply just searched this forum.

Would probably have saved you quite some effort.

Also like the title says, this thread is about the KERNEL, not about radio.
[Atrix 4G Android Development] rhcohen:
FWIW I did download the radio from that link, to my computer; the problem was transfering the file from computer to phone. I had fooled myself into thinking I was flashing a good radio file as I looked at the checksum only on the computer. After I was aware of the problem I downloaded, using the link you posted, directly to my phone. Checksum matched, and flashing was successful.

As to why I posted about the radio here -- because some of the variable behavior with modem drops, google voice recognition failure, etc., which are being traced on this thread, seemed to have some correlation with radio. In particular with the 37P radio and the best kernels (2/17, 2/22) I could rather easily induce data drop by using google voice recognition via cell data. [MENTION=462587]Voldemort[/MENTION] seemed to be having better luck, and the only difference I could find in configuration was the radio. And today after upgrading the radio, it seems my experience is closer to Voldemort's -- google voice recognition seems to work over cell data, and doesn't seem to be leading to modem/data drops. But I don't yet have sufficient experience with this radio to draw a firm conclusion.

I am however still having a problem I reported earlier: I can be doing nothing on the phone except have Android Assistant open, and watch the available memory slowly but steadily drop.
[Atrix 4G Android Development] Voldemort:
I am not sure if it's kernel related or not, but while using Waze (navigator app) over 3G after a while the data connection apparently stops working and also the GPS position seems incorrect.

I did a few tests and some times while Waze does not work anymore, Google navigator can still get the position and trace the route.

Is it app related?

Good to have you back!

Using your latest kernel my phone has been much, much more stable, though with mediocre battery life and slow cell data speeds (I recall you saying you'd removed the battery optimization for troubleshooting purposes). I've only had a couple of hard freezes, and those only happened when I had powerful magnets installed in the case. I'm not positive they're related, though - do you know if strange behavior from the phone's compass could cause instability?

[Atrix 4G Android Development] PolesApart:
I'm using a 02-02-2014 kernel and had no more than 5 hard modem drops since them. ppp disconnects a lot (yet, no more than other kernels - every single one i've tested since 3.1 kernel appeared had this behavior on epinter's cm 10.1, and IIRC even 2.6 had it too).

Afterwards I tried one or other kernels but always could get a hard modem drop on the very same day of changing it. Some was even worse.

The only thing I can complain about (besides the well known bugs as BT handset) is the speed. I've played with a dozen or so android devices, and every one of them got laggish at some point e.g. when google play is installing app updates. But on this device, it's not just laggish, it's absolutely unusable, for minutes even. When that happens, trivial things such as answering a call are impossible sometimes. Someone else faces this?

I'll try this kernel and compare it to my current one, at least about modem drops. If I don't ever come back is either because I died or it's as good as
