I'm struggling with this

I've had experience rooting htc hero and htc desire, but started rooting the Xoom for the first time yesterday.

On a couple of occasions I thought I'd bricked it but I don't think it's that bad.

Currently I'm using this recovery recovery-Tiamat-R4c-100611-1150-cwm.img

I've also flashed ElementalX-Xoom-v0.7-cm-wingray.zip

and also this gapps-jb-20120719-signed.zip

When it boots it gets to the CyanogenMod screen with the circling cyan lights. And there it hangs - I've waited over 15 minutes but there's no change.

I used this because I tried the 1.3 version with no success, but I'd read about other people trying earlier versions with success. I also read that someone said it worked when Gapps was installed as well.

Maybe I've got the wrong combination of recovery/rom any advice gratefully received

p

When I do flash roms it seems to be very quick - 3 seconds or so. I'm sure it should take longer. I don't think things are being written properly but it says complete - and doesn't feedback an error message

I think there's a problem with accessing davlik cache. When I try to wipe the dalvik cache it just flicks back to the previous screen without giving me the option of selecting yes

Select "wipe cache partition"

Select "Yes - Wipe Cache"

Select "advanced"

Select "Wipe Dalvik Cache" ------------------ I can select this, but then don't get the option to select yes

Select "Yes - Wipe Dalvik Cache"

Select "+++++Go Back+++++"

Not sure what this means but it may be the problem

Have you Bigparted?

From the recovery you're using which doesn't look to support Bigpart it would suggest you haven't done this, which is probably why its not working. Hope this helps!

Error loading kernel after self-compiling

Hi,

I want to compile the ElementalX sources in order to test some changes but I can't successfully load kernel after compiling it myself. I'm compiling the master branch and using elementalx_defconfig. I've tried linaro 6.3.1 and linaro 4.8-2014.3 but my kernel binary is 0.1 MB bigger than the included in the zip file from the first post. It could be a problem? I replace zImage in the zip file with my own version. After flashing it and rebooting the boot process gets stuckd in the moto logo. I've tried to debug it but I can't find any helpful info because /proc/last_ksmg doesn't contain valid info from my own compiled kernel. I can't guess what's is happening, does somebody experienced issues when compiling the kernel by his own or I'm missing some crucial step?
[Xoom Android Development] flar2:
^^I don't have that device. Something like s2w would be really hard to add to a device if you can't test it.

***********************************************************

Back on the xoom, I will be doing some updates and other work on this kernel.

Unfortunately for you guys, a few days after I started work on this kernel, source code was unexpectedly released for my main device. So I've been preoccupied with development on the HTC One X the past week or so.
[Xoom Android Development] shpitz461:
Thanks for the update, and no rush...

Maybe you'll have some time to look @ the Stingray issues as well :)

huge battery drain... any tips? im using myandroid 4.2.2
[Xoom Android Development] flar2:
You'll have to be a little more descriptive.
[Xoom Android Development] guitmz:
i was on myandroid 4.2.1, it was perfectly fine (for example, days of stand by and low battery drain) and i was using shield kernel.

flashed 4.2.2 with this kernel, turned off sleep2wake just in case and change the governor from ondemand to dancedance.. this night, i got like 10% of battery drain on stand by when before i used to get 2%, 3%

the only thing i did was overclocking it to 1408mhz (but this state hasnt been used so far)

:)
[Xoom Android Development] flar2:
I think it's 4.2.2. My wife has been using the xoom a lot lately and I notice she's been running out of juice more often since I updated to 4.2.2. Was using EOS 4 before that, and My Android 4.2.1 before that. Sweep2wake shouldn't cause a noticeable drain.

I'll follow the battery stats a bit more over the next week.
[Xoom Android Development] guitmz:
i'll give u and dreamcwli a report later today!
[Xoom Android Development] flar2:
Also try a different governor, I haven't really tested dancedance, just tossed it in there.

Had a couple lockups, been running it for about 3-4 days and had it freeze up twice while asleep. SOD? Currently using interactivex2 min 456 max 1504. I am going to try a different governor and see if it helps. This is on EOS4 latest nightly(177 I think).

so happy to see some more dev'ing for the xoom - thanks so much!

i just installed this morning and occasionally when using sweep2wake i'll get a blank white screen instead of the lock screen. a quick toggle of the screen with the power button usually fixes it, but just thought it odd. trying to recreate why it happens and seems to be random. running eos4 nightly 178 - wingray.

Nice job just installed your kernel to my Xoom. Reading the header I thought there was NTFS read/write support but when I tried to write to my USB flash drive I couldn't is there something I am doing wrong?
[Xoom Android Development] flar2:
When I have a chance I'll make a sweep2wake patch that should apply to any xoom source tree.

If this happens again, please send me /proc/last_kmsg

Thanks, still got your HOXL?

I haven't experienced this, I haven't tried 178 though. Last one I tried was 177 and I've been running My Android 4.2.2 all week.

It depends on the ROM you're using. I tested using StickMount and it works that way. You can find it in the play store.
[Xoom Android Development] dreamcwli:
The NTFS write support in kernel is actually a replacement support. You have to use some apps to get the real NTFS write support.

Re: [KERNEL][Feb16] ElementalX-Xoom-v0.5 | OC | UV | GPU OC | ZRAM | SWEEP2WAKE

Running the kernel with EOS 178 I got many reboots with most of the custom governors when trying to OC to 1600. With dancedance it's working. Before trying ElementalX this was not an issue for me.

Anyways, thanks for the great work!
[Xoom Android Development] recognitium:
Re: [KERNEL][Feb16] ElementalX-Xoom-v0.5 | OC | UV | GPU OC | ZRAM | SWEEP2WAKE

Tested briefly Elemental X and sweep2 wake is great. I reversed mainly because neither BT keyboard nor mouse were working with it. As far as I understood that was a problem in earlier EOS 4 (up to 164), but they had fixed it. Sorry if I mix things up since I am not sure if this is kernel or ROM issue.
[Xoom Android Development] flar2:
Should be back working on this again soon.

For now, I've posted a sweep2wake patch in the OP.

Still some work to do to improve it, but the patch can be applied to any xoom kernel source as-is.

Feel free to use it, give me credit if you do.

I tried this kernel out on the recent Orca builds. So far so good, seems to be working well. Haven't done alot of testing with it yet though but it installs and works fine. The stock kernel(CM based) was giving me random reboots so decided to give this a go. I wasn't sure how successful I would be but I was pleasantly surprised it booted up perfectly.

Thanks for this flar2, trying to get used to using Swipe 2 wake. I love it but hard to retrain myself not to use the power button. :silly:

[Xoom Android Development] ouldsmobile:

[Xoom Android Development] Dafonse:
I installed this kernel and forgot to wipe, now the xoom gets stuck at the rom logo and wont go any further. I have tried to get back to the clockwork mod settings but none of the button combinations work, the up button gives me starting RSD protocol Support, down gives me starting fastboot protocol support, both buttons gives me powering on bp.........Never ran into this problem before so was wondering if you guys had any advice or experience with similar issue.
[Xoom Android Development] shpitz461:
Boot with down-vol + power.

wait 3 seconds then press down-vol

you'll get a 'menu' with a single line @ the top.

press the down-vol to scroll between the different option

press up-vol to select (like 'enter')

worst case you can always flash back the original kernel, just extract boot.img from the zip (of the ROM) you flashed originally (and flash with fastboot using the command "fastboot flash boot boot.img").

You can also flash in fastboot mode using fastboot.exe util, you can also clear cache with fastboot:

fastboot erase cache

So you don't really need to be in CWM to erase :)

I am using sweep to wake and when I re all I have it and it works it is very cool. However, I don't always remember and I busily press power button and then try sweep to wake but now nothing works. So volumes and power button for a hard reboot. Somehow I will figure it out. Thank you for the work.

How 'bout some Stingray/Stingray LTE luv. We would also like to use the Sweep2Wake and other options that you have to offer. I hear good things about your work. I actually flashed your kerney on my mz602, (knowing that it would loop on boot) lol and it did. But afterwards, I fastboot'd a boot.img it booted and I was able to see your "zRam" in terminal after typing "free" so that part took. If you need an mz602 boot.img let us know.

EDIT - How 'bout some 4.1.2 Stingray/Stingray LTE luv.

I'll really need your help for Stingray, since I don't have one.

Try flashing this boot.img on Stingray: http://goo.gl/CmjxD

If it boots, could I get dmesg output? In terminal or adb shell:

dmesg > /sdcard/dmesg.txt

And kernel config:

zcat /proc/config.gz > /sdcard/config.txt

If it doesn't boot, then /proc/last_kmsg. In terminal or adb shell:

Is it the latest version? About screen showed it as v0.4 from Feb 12.

Yep, and it works great, I can turn 4G on and off, reboot, no issues.

I also flashed EOS4 174 last night, will continue testing tonight.

SmartAssV2 was very slow when playing a card game. The tablet was very slow to response. tried Interactivex2 and lionheart and both appear to be ok.
[Xoom Android Development] flar2:
So all that was needed was a different ramdisk.

I mistakenly put the zimage from 0.4 in the boot.img.
[Xoom Android Development] shpitz461:
Cool, so you'll get a new version out? what is the difference between Wingray and Stingray? What was missing before (any version in the OP) that wouldn't boot?
[Xoom Android Development] Mjamocha:
Sooo... nothing for 4.1.2?
[Xoom Android Development] flar2:
^^in time, I only have one xoom and I can't constantly change ROMs or I have no baseline for testing the changes I make to the kernel. Have you (or anyone else) tried to boot this on EOS3? What happens? /proc/last_kmsg or dmesg output would be helpful.

The only difference is the ramdisk and command line. I thought for sure I was going to have to add some weird driver or something. I'll be posting a stingray installer with version 0.5 later tonight.

I have an issue with this kernel. When my Xoom (Everest with EOS 4 #146) is unused for many hours (from 3 to up) I can't wake up the device with the sweep neither pressing the power button. The only way to power on the Xoom is with the combination Power Button+Volume Up. This is some sort of reset and not a real wake up. Any suggestion? And how I can set the volt for the frequencies, because I want to undervolt the beloved Xoom.

Ok, there's a problem: after i shut down tethering, wireless can't find 5GHz network anymore. Turning wifi off and back on doesn't restore it, still says 'not in range'.

It's as if the 5GHz radio is turned off by the tethering and doesn't get turned back on.

Only way to fix is to reboot.
[Xoom Android Development] emaxxim:
After i posted my issue i flash the new EOS #147 and then reflash the 0.5 ElementalX Kernel. In about ten hours everything works fine (by the way there are many hours od deep sleep for the device, cause I'm sleeping too tonight). This morning I play with some game and the sweep2wake still working. When I shutdown the display the battery is at 51%, now after three hours the same problem: the sweep2wake doesn't work, neither the power button and the lower right corner of the screen is warm compared to the rest. I reset the xoom with vol up+ power button and now the battery display there is only 18% of charge. Down there, is the log you requested to me. I hope help you so maybe I can use this amazing kernel.
