[Galaxy Tab 10.1 Android Development] kasper_h:
I have to correct myself. I made a mistake when building stock 2.4.4.0 (my build script automatically checks out to my local tree). I redid it properly and now the recovery.img size is 5.259.264 bytes. So a few bytes too large.

But with the "TW_EXCLUDE_SUPERSU := true" flag, the recovery has a size of 5.177.344 bytes.
[Galaxy Tab 10.1 Android Development] AAccount:
So it looks like you didn't need to take quite the drastic measured that I used to get twrp 2.4.4.0 to fit. Actually, when I did twrp2.4.3.0 a few weeks ago I did try less severe measures but I still couldn't make it fit. Then, when I did twrp 2.4.4.0 this weekend I just figured I'd go with what worked for 2.4.3.0. In those few weeks I was offline, twrp 2.4.3.0 worked fine for me with those severe space saving measures so I deemed them ok for long term use.

Now the question is, have you gotten a 3G version to work properly of versions > 2.4.1.0? I use the exact same BoardConfigCommon.mk for both the 3G and Wifi but for some reason cannot get the 3G version to backup/restore correctly. Perhaps you've had more luck or more free time to get a 3G version working?
[Galaxy Tab 10.1 Android Development] kasper_h:
The issue is that I don't have a 3G tab. So I only build for wifi. And I don't feel comfortable testing 3G on wifi model...(semi-bricked my phone recently with testing for a slightly different model...).
[Galaxy Tab 10.1 Android Development] kasper_h:
The 3G recovery.img is 0.4MB larger (without su)...so that indeed would require more work to get it to fit...

The odd thing is that with my personal changes to TWRP (some theming) it gets to 5.2MB again so it should fit. No idea why ?!

Now i just have to find a volunteer to test whether it works :)
[Galaxy Tab 10.1 Android Development] AAccount:
Well, after the unpleasant 5something trials I did yesterday with backup and restore failing on the 3G version I'm a bit hesitant to try it again. I actually don't mind if it tells me restoring the system partition failed because a zip flash can always take care of that. I just don't want to have a failed data partition restore and be caught off guard without a working backup.

Unfortunately for now, this means I probably won't make recoveries for the 3G version. And besides, no really revolutionary deal breaker features have come out since V2.4.1.0. I think most improvements have been incremental, but, there's just that psychological satisfaction of knowing you have the newest version.

Also, TabletMod will take an extra step to make from now on because of the new CM commit that breaks compatibility even further. That will eat up more of my time too.

I'll test the 3g recovery if you like.

I'm comfortable enough to fix back to normal if it doesn't.... as long as it doesn't fry my partitions! :)

Worst case I can Odin a working recovery, or even restock
[Galaxy Tab 10.1 Android Development] AAccount:
It won't fry your partitions but I would make a backup with a known working recovery to be safe. Didn't fry any of my partitions when I tried it yesterday but had to rely on my February 22 backup to get things going again.

Well, mate I managed a backup, a full wipe, and a full restore :)

Using TWRP 2.4.4 from the AAccount CWM attachment above ^^

Had a few "E:A render request failed" messages along the way in the running log BUT it restored just fine

GOOD progress, well done!

Glad to know it cooperated for you. I'm not sure why it didn't work for me.

got this "render request failed" multiple error while making a backup with the 2.4.4.0 wifi version. It ended with "success" message, but i'm not sure what that error means, and whether it affects the backup in any way.

I was using twrp 2.2.x version (i think it was an older version from this thread) and just flashed 2.4.4 over it, then went to make a nandroid first thing and noticed these render errors.
[Galaxy Tab 10.1 Android Development] AAccount:
Ok, I added a note to the first post about the render error. Basically it's not harmful at all and should not be a cause for concern. I even underlined, bolded and put the font color to red for the notice about the render error. Hopefully that should get peoples's attention.

Re: [Kernel/Recovery/MOD][P75XX] A1 Kernel V1.8.4/TWRP2.4.4.0/TabletMode

Flashed the provided zip. Everything seemed to have worked until I go to settings which causes a reboot every time. Has anyone encountered the same issue when they flashed the zip? I haven't tried doing it manually as AA originally suggested. Appreciate if someone can point out what i'm doing wrong. I'm on latest CM 10.1 nightly 3/28.

Thanks!
[Galaxy Tab 10.1 Android Development] hanspampel:
Maybe try this zip. It should work without deleting if anything. Its build from 3/27 nightly.
[Galaxy Tab 10.1 Android Development] enmriley:
AAccount,

Just a note... I downloaded 1.4 just before you loaded 1.5 last night. It seems when I power down, the unit shuts completely down, ibut then reboots. I have since gone back to 1.2 and it does not have this problem (that is I get the battery charging symbol).

Any chance you can post the stock kernel in a zip format... I would like to keep in on the tab in case I ever need it.

Thanks for your efforts.

Stock US ICS rooted, WiFi, kernel version 1.2
[Galaxy Tab 10.1 Android Development] jaswinky:
Yes, you are right, my report is wifi connected , but with no user transfers...

Now, see attach pic, this is from my galaxy s2, you will see most time in offline mode (i think same state as your sleep mode), and most that time corresponds to the nights, i sleep wirh the phone on, screen off, wifi on... I mean, i dont think to be connected to wifi with no activity should be a problem to enter in offline mode, the problem could be in the wake up events... While my s2 only need to go from sleep to 25MHz. , the tab is obligated to go from sleep to 216MHz...

Thanks,

[Galaxy Tab 10.1 Android Development] jaswinky:
Note that in both cases, tab and smartphone, de second more usual freq state with no activity (200MHz in s2 is requered t unlock the screen) is the minimal freq, 25MHz in s2, 216MHz in tab... so, I'm really sure if the minimal freq would be less than 216MHz in our tab, the drain batery would be much lower.

Also note that sleep or offline mode is not a "real" 0Hz cpu state... if so, the wakeup or ingoing call events couldn't be started (!!)

Regards,

I just quickly skimmed your report first but I forgot to say between 1.5experimental and 1.5release, I changed the current report from current_average to just current. (I'm assuming this means instantaneous current). That might be why you got 1.5A on a 1A charger. I'll upload a version with AC always but reporting current, not current_average.

Thanks for the report. I'll read it carefully now.
[Galaxy Tab 10.1 Android Development] jaswinky:
Perfect, I'll just compare some values to check the diff.

All old versions have been uploaded again. Sometimes you have to reflash the kernel if something weird happens. This happens to me occasionally in testing. I use the TWRP recovery.
[Galaxy Tab 10.1 Android Development] CazeW:
Don't know what's going on with your tab but I tested with mine and when I put wifi always on, I never got to deep sleep even when I wasn't transferring anything or connected to a network. Try testing with CPY Spy, it could be that your app is reporting wrong.
[Galaxy Tab 10.1 Android Development] AAccount:
There's the 1.5 version with the battery reporting the "FG_CURRENT' instead of "FG_CURRENT_AVG".
[Galaxy Tab 10.1 Android Development] jaswinky:
Thanks!

One issue: some people on the spanish forum (htcmania) are reporting a hangup on start after flash 1.5, it stands infinitely on first samsung message. I happen it once with 1.5, but never with 1.4 or previous 1.5experimental. I just pushed the power button some seconds to restart, and it restarted with no problem...

[Galaxy Tab 10.1 Android Development] AAccount:
This might have to do with 1.4GHz OC. I only started getting these weird issues after tinkering with 1.4OC. 1.2OC never gave me problems. Should that be removed or a separate version made with all the features except capped at 1.2? That would be harder to keep track of and make sure the right versions are being compiled properly. From my experience, anything more than 1.2GHz with these kernel sources can (but NOT necessarily will) produce a moody tablet.
[Galaxy Tab 10.1 Android Development] AAccount:
That would be hard for me since I don't want to constantly flash back and forth between stock and JB. I need the front camera of stock ICS right now, which is the whole reason I started to make this kernel: keep the features I liked in HC after the upgrade.
[Galaxy Tab 10.1 Android Development] CazeW:
If you want to separate the 1.4GHz from 1.2GHz I recommend doing it the way pershoot had done it, namely having a TEGRA_OVERCLOCK setting that turns it on from the .config. That way you just need to have two different config files.

---------- Post added at 09:41 PM ---------- Previous post was at 09:32 PM ----------

It seems that it was my tab acting up, now it goes into deep sleep even with wifi always on. But my statement still stands, as long as the device is in deep sleep it doesn't matter what the minimum frequency is. When it wakes up by wakelocks, having a lower minimum frequency could have a small power saving effect. Anyways, it's all up to AAccount if he wants to implement it. Personally I don't think the difference would be that big but I could be wrong too.
[Galaxy Tab 10.1 Android Development] jaswinky:
I did never happen with 1.4 version...

[Galaxy Tab 10.1 Android Development] AAccount:
When I started tinkering with V1.4GHz OC after V1.3 I sometimes got the "Galaxy Tab 10.1 stuck issue". When I flashed trials of V1.4 and V1.5 it didn't happen often but a few times did this. What solved the problem for me was simply reflashing the kernel again. That's why I suspect the 1.4 GHz OC is behind this. Before releasing V1.4 nobody reported this issue and I didn't have this issue either. It's odd that V1.4 works butV 1.5 doesn't for some since the only change has nothing to do with the clock settings but the 1 thing V1.4 and V1.5 have in common the the 1.4GHz OC.
[Galaxy Tab 10.1 Android Development] CazeW:
I haven't had a single stuck issue with my 1.4GHz kernel after I got it working. I don't know if it actually makes a difference but I've copied from pershoots git (check his galaxy-31 sources) the settings so that you have adjustable MIN/MAX frequencies for init/boot. Those are set to 216000 and 1000000 respectively and I've also disabled CONFIG_TEGRA_CPU_FREQ_LOCK in the config file.
[Galaxy Tab 10.1 Android Development] AAccount:
Does 150MHz min sound good or should it go even lower. Testing 1.6 150MHz min right now.
[Galaxy Tab 10.1 Android Development] CazeW:
A small sidenote, lowering just the frequency won't have that much of an effect on the drain unless you also lower the voltage. For example running 150MHz and 216Mhz on the same voltage has almost the same amount of drain (theoretically). Unless you knew this already. :)

[Galaxy Tab 10.1 Android Development] hanspampel:
Hmm strange. I cant check it with GTab, but on my N10 its running good. Without any problems. So maybe try with complete fullwipe and format system, or i can made a newer one from latest nightly if you want and you try this with actual nightly.

Re: [Kernel/Recovery/MOD][P75XX] A1 Kernel V1.8.4/TWRP2.4.4.0/TabletMode

Perhaps it is indeed not compatible with p4wifi. I dont think i will be doing a fullwipe just to install a patch. If anyone can confirm that AA's patch worked for their p4wifi with CM10.1 nightly (3/28) then i might try again using his posted steps. Otherwise, might look into other roms that support hybrid mode. Thanks anyway for the help.
[Galaxy Tab 10.1 Android Development] hanspampel:
It should work with 4wifi too. I postet this MOD in german forum as well. But no one seem to have the problems. Maybe try newest nightly(3/30) with this attached MOD. The older ones doesnt work anymore with the nightly from toady!!!

TabletUI is proving to be much harder to get working. It looks like there won't be an update to it for a while since finding a fix with my limited skills is going to take a while. If anybody else has more time or skills to get TabletUI working please put your suggestions. I personally won't be flashing my own tablet for now since I can't stand the ugly 2 bar UI, especially with the lag it introduces. Part of the problem appears to be the new pie controls throwing in some new unexpected problems with the reversion process.

A quick glance through the development section of the GT10.1 shows that Task650's AOKP has a more elegant solution for the classic tabletui and he has quick settings working. Anybody tried that and can tell me how that compares to my tabletui mod? With the current rate of difficulties getting tabletui to work, I really put it up for question how much longer I can keep it going by myself.

[Galaxy Tab 10.1 Android Development] yopet:
Hi guys!

I need to ask few questions because I'm not sure I understood what's going on exactly...

I saw in some other thread(s) that there is a GT-P7500 TWRP version 2.2. That is the newest build I have found so far for GT-P7500. The build I see in this thread for GT-P7500 (3G) is 2.4.1.0.

I am currently at CWM recovery 6.0.3.0 and stock ICS 4.0.4 (stock kernel 3.1.10). I had to encrypt the tablet and that's why I am looking into CWM recovery alternative. I would like to be able to create nandroid backup(s) of this encrypted tablet and I have read somewhere that TWRP is capable of making such backups.

In the change logs for TWRP I see that there are some decryption features and/or improvements implemented since version 2.4.0.0 onwards.

Now the questions:

Having in mind the details of my rom/kernel, is it safe for me to install the 2.4.1.0 version on my tablet?

Is it possible to make nandroid backups of my tablet with TWRP 2.4.1.0?

Thank you very much in advance!
[Galaxy Tab 10.1 Android Development] AAccount:
My tablet isn't encrypted. I'm really not sure how twrp will play out with that. I'll probably make the 3G twrp 2.4.4.0 official on this thread since the feedback a while ago was all positive. Anybody else tried twrp with encryption?

Also, if anybody is willing to share how to make tabletui work on newer builds I would very much appreciate it. I tried last week to make a new one but ended up messing up my CM10.1 sources. From now until the end of the month I have exams again and trying to fit in my social life and somewhat part time job in there will make it hard to work on my tablet so I probably won't post anything new until the end of the month. (My good friend is also taking me to see my first ever concert somewhere in there too!!) And yes, unfortunately, I have to live with the 2 bar UI for now. :crying:

On that chinese kernel, I think that would be a binary which makes it not possible to apply to my kernel. Also, I don't feel like doing a rebase on every single kernel source variant put up by Samsung just to hunt down the 1 out of many that will have the fix at the source. That would be rather tedious and time consuming.

And... all my gadgets shown below are finally opted in to the CM stats.

Surprise Update

I was going to take a shower so I thought I'd just do the usual 3 step process to make tablet ui to see what happens. Around March 23rd, the usual 3 step process failed me so it turned into something like a 9 step process. I tried to repeat the same 9 step process last week and it failed miserably. Had to end up redoing the frameowrks/base folder of my cm sources So like I previously mentioned, I thought before I go to shower I'd do a quick 3 step on my newly fixed sources and set it to compile. When I came out of the shower, adb'ed the new files and it works!!
