hi timduru

despite total success with my "other" tf300t with this set up, i have found that twrp 2.8.7.0 is reluctant to allow f2fs format on the data folder

2.8.1.0 was a happy camper, so is twrp the problem ? is this a known issue to you ???

and ho ho ho, regardless :)
[Transformer TF300T Android Development] mickmik:
Hi,

I erased everything "fastboot erase xxxx" all partitions.

I installed stock rom.

I installed twrp kang.

And ... I have bootloops on splashscreen.

Someone could tell me what is wrong with my tablet ?

Thanks a lot.

Sry for my English.
[Transformer TF300T Android Development] DriftJos:
I don't see you saying that you installed GAPPS and SuperSU. Did you install those? If not, I would do it all over again and install those ones too. Follow the instructions exactly and it should work.

Also, don't forget to format data to f2fs, it really helps.

---------- Post added at 09:52 AM ---------- Previous post was at 09:38 AM ----------

Try the KANG version of TWRP and it's working fine. Had the same issue and discussed a few posts ago.
[Transformer TF300T Android Development] scruffy1:
ho ho ho..... d'oh ! :silly:

thanks for the reminder

happy christmas, and i'll give it a try and report back
[Transformer TF300T Android Development] mickmik:
Yes, I also installed Gapps and SuperSU.

I don't understand what happens.
[Transformer TF300T Android Development] pe1dnn:
You say wiped everything and installed stock first. Did you boot to stock to let it initialize everything before you continued with TWRP? Stock has to work properly before you can continue. The stock image will format all other partitions if they are not yet initialized (which they are not after erasing with fastboot).

After installing TWRP you first have to boot to system before going back to recovery, if you go directly to recover after installing TWRP you also get a boot loop.

Basically, verify after each step before taking the next, however Katshmallow, gapps and super-su shall be done as one step without rebooting in-between.

I hope this helps.
[Transformer TF300T Android Development] mickmik:
Thanks again. I'll try to make it like that.

Wait and see...
[Transformer TF300T Android Development] mickmik:
So, I just did this steps really carefully:

1. In bootloader, fastboot erase system, recovery, userdata, boot, misc, cache.

2. Fastboot flash blob (stock from Asus.fr)

3. Go to my fresh install (everything was good)

3. In bootloader, fastboot ... TWRP.

4. Go to the stock from (works fine)

5. Go to TWRP

6. Wipe cache, system, dalvik

7. Flash rom, SuperSU, Gapps

8. Wipe cache, dalvik then reboot.

And ... Bootloops !!! I can see the LSD dog and it stuck then reboot it self

TWRP was Kang 2.8.7.2

What can I do ?

Thanks again and again...
[Transformer TF300T Android Development] scruffy1:
dunno about kang twrp, but i found that twrp 2.8.1.0 has been bulletproof

i "accidentally" upgraded my 2nd tf300t to 2.8.7.0 - and it refused to format f2fs, and then trapped me in a bootloop also

i eventually fastboot booted it into 2.8.1.0 using the computer after an afternoon of exasperation, and i am only just now watching the initial bootscreen with the meerkat

it took a hard reset using the pinhole near the sd card to reboot it, and then when it was at the rck screen i used :

fastboot -i 0x0xB05 flash boot twrp.blob (which was a lucky dip command i found after immense google-fu)

thereafter everything worked like timduru's instructions - might be safer to wait for a nerd of merit to confirm this is appropriate, but it seems to have worked for me :)
[Transformer TF300T Android Development] mickmik:
Thanks but you can't have f2fs with 2.8.1.0 ?!
[Transformer TF300T Android Development] scruffy1:
is that a question or are you stating it can't

i can totally assure you it is working fine on not one, but now two tf300t's using katkiss 6 and only the data drive rejigged as f2fs while the rest of the partitions are on ext4

exactly as timduru directs to do in the instructions, and humming :good:

2.8.7.0 is no good for f2fs, but 2.8.1.0 is happy - i am uncertain of the intervening versions being good, but as i already had one complete success with 2.8.1.0 :victory: i wasn't keen to see what else might fly :confused:

sorry, i got the number wrong in my initial post, now corrected in bold font
[Transformer TF300T Android Development] mickmik:
Hum, with 2.8.1.0 there is no option to format data as f2fs, just exfat etc..
[Transformer TF300T Android Development] scruffy1:
after the initial format (ext4, which takes a long time) you need to go wipe > advanced wipe and tick data, then hit "repair or change file system" and then you get the option to change file system and choose f2fs

hope that helps :)
[Transformer TF300T Android Development] mickmik:
Maybe I found a tuning version ! I try an official
[Transformer TF300T Android Development] scruffy1:

[Transformer TF300T Android Development] mickmik:
Yes, obviously I found a funky version [emoji16]

I try with this good one
[Transformer TF300T Android Development] scruffy1:
good luck - no problems here (apart from the days of work it took me to find out how to fix my own stupid mistakes, and happen upon some useful extra commands, given i am as fluent in android as i might be in martian) :p
[Transformer TF300T Android Development] mickmik:
Ahah.

I have another problem now ! It stuck in meerkat and four balls. It not a dog ?! Hum
[Transformer TF300T Android Development] scruffy1:
might not be stuck

first boot is very slow as it builds... and if you succeed, don't rush to the initial configuration - leave the rom stabilise for half an hour so it plays nice once you use it
[Transformer TF300T Android Development] mickmik:
Should I wait more than 15 min in splashscreen ?
[Transformer TF300T Android Development] scruffy1:
just re-set mine to try, and only took a few minutes... but i usually walk away and do other stuff at this point, and for another 30 minutes after the initial config screen appears

anything less complicates my life after i discover i have ruined the build by pushing it

when mine showed the kat for as long as you said, it wasn't a clean install

you have to meticulously follow the instructions, and that includes the initial wipe of all the partitions that timduru says - which is 10+ minutes easily; then reformat the data as noted, and then wipe dalvik yet again

then go for install

sometimes it takes several tries (my first go did, and it was in retrospect due to my keenness to not do all the steps patiently

add the zips in the order stated - kat 6, then superuser, then the apps

make sure your superuser file isn't crap either... i found the one suggested here (kang) didn't seem to do so well, but UPDATE-SuperSU-v2.46 worked for me

perseverance will pay - this rom is very good once you get it up

when you eventually get to "android is starting" there's another 10+ minutes, after which you should let it just settle on the welcome screen for as long as you can stand - the minor things you rattle by being in a hurry will only get discovered later when some things don't work as you expected, whereas with the patient approach they are faultless
[Transformer TF300T Android Development] mickmik:
I did all steps patiently. Again... I take a break !

Thanks a lot for your help [emoji169]
[Transformer TF300T Android Development] scruffy1:
you're welcome

several people here did the same for me, so pay it forward by all means

i again thank timduru for such an excellent refurb for the tf300t - it is like a new machine :D
[Transformer TF300T Android Development] ch3mn3y:
Anyone unpacked boot.blob? I would like to stay with Xubuntu, so I want to use kexec kernel, but for this I need zImage and initrd.img, however I don't know where to find boottools and blobtools working with MM. The one I got are giving me that kernel from last build is "not valid blob file".

Thank you very much again for your amazing boot animation!!!

I completely disagree with it. ext4 works well on my tablet. Moreover, I don't want to use f2fs until the final version will be released. My information is more important for me than little bit more speed on the raw and unstable file system.

Thank you very much for your useful answer. I hope it is possible to remove this stupid doze mode. But if not, I must try some software to keep my Wi-Fi on. Anyway, keeping Wi-Fi on for having important calls is more important for me than battery life.

Yes. I have exactly the same issue. Hope, it will be fixed as soon as possible.

I totally agree with you. This is definitely a ROM issue. Wi-Fi works perfectly on the stock ROM.

Hi, liljom.

Unfortunately, not. There are still Wi-Fi problems in #11.

That is wrong command. Here is the correct command.

fastboot -i 0x0b05 flash recovery twrp.img
[Transformer TF300T Android Development] Ozzie12:
I am loving this rom...it feels like a new device and am very thankful.

But...I see the second battery from my keyboard doesn't show up on my widget.

Is this something to do with the kernel?
[Transformer TF300T Android Development] scruffy1:
i realise that is the normal command, thanks

sadly my tf300t was completely ignoring it, as it was somehow stuck and i am not nerd enough to appreciate the subtle reasons, but i am able enough to recognise that "doing the same thing again and again and expecting different results" is how einstein defined insanity :silly:

having happened upon the command line i figured it was telling the tablet what i wanted it to do, and it worked, although i had to use the pin reset to get it into the rck screen as it had been bypassing that on every reboot regardless of how i tried :mad:

prior to that adb devices returned 1234567890abcdef and another word (that i have forgotten, but which wasn't there whenever i asked for devices after successful link)

i still don't know exactly what happened, but the tablet is now humming along like its doppelganger and i am staying with 2.8.1.0 :D
[Transformer TF300T Android Development] DriftJos:
In my opinion this 'stupid doze mode' is not that stupid at all. I am not using my tablet a lot and I am really happy that, I think because of doze, my battery lasts far more than a week and I do not have to charge it first the moment I decide to pick it up and use it.
[Transformer TF300T Android Development] pastorbob62:
If it was a ROM issue, then how do you explain so many users without any WIFI problems who are using the same ROM? I think it goes back to a previous post that mentioned two different versions of WIFI hardware on this tablet. That combined with the wide variety of hardware used and it points to hardware, not ROM.

---------- Post added at 11:06 AM ---------- Previous post was at 11:03 AM ----------

On some tablets. Not seeing any WIFI issues whatsoever and I have been using #11 since its release. I suggest trying it and if you have issues restore your backup.

bug: press power button twice for camera

it doesn't work for me on #11

screen off, press twice > nothing

Wifi

Those who have issues with Wifi, try to flash this and report back: Tim_KatKernel_024-t6_TF300T_MM6.0.1.zip

It's still a WiP , but before going further I'd need to know if it's fixing some of the reported "issues" or not.

From what I have gathered so far there are different things reported

Please do not mix the issues, by replying "me to" to an issue that has nothing related to yours, that just make it impossible for me to try to gather useful information,

Do not reply to another issue without context

Always state clearly what is / was your issue in every of your post / replies.

Do not reply or repost every few days for the same issue over and over again.

And of course make sure that you made a full clean install with a FORMAT of /data before reporting an issue. (try f2fs to make sure we're testing with the same base)

1) Wifi turning off when sleeping / dozing

: that's a wanted behavior to me.

So if you prefer it otherwise try to flash the attached zip, it should allow wifi to stay mostly on.

Not sure if the "Keep wifi always on" option is not creating more trouble than anything and is incompatible with the new doze mode or not though..

I might just get rid of it.

Also remember that If you want an app to be able to notify stuff you need to exclude it from doze mode (Battery optimization)

To maximize the notifications also exclude these 3 from battery optimization: "Android System" + "System UI" + "Settings"

And before someone complains about battery life, changing that will of course decrease your battery life compared to the current default version.

2) Wifi group rekeying causing wifi reconnection with some routers

.

- Change the group rekey interval on your router to a higher value or 0

I don't have the issue so it's difficult to know, but also try the attached zip, it might help on the issue , as the wifi driver is more recent.

If you still have the issue, try KatKiss Lollipop after a full wipe / format of /data

That would help to know if you have the issue in Lollipop

3) Unstable wifi, not reconnecting

:

I don't have issues either, so I don't know, might be hardware related or router related.

- try to change the router channel to a channel lower than 10

- try to change wifi regulatory domain in Wifi => advanced

- try the attached zip.

If you still have the issue, try KatKiss Lollipop after a full wipe / format of /data

That would help to know if you have the issue in Lollipop

As a reminder when reporting

:

- Post the full set of logs.

- Describe exactly what is your problem, what were you doing just before it happened and so on, when was it (approximate time), any indication to help me find the issue in the MB of logs.

(basically follow the How To Report link)

If you can't do that, don't post in the Dev thread.

This thread is made for helping me to progress on issues, if you're not able to help by giving useful info, don't post, as it just creates confusion for other users and myself.
[Transformer TF300T Android Development] frank.devliegher:
I know this is a TF301 based thread, I just want to drop a question about using this rom on a TF201. I am using the [MENTION=3951330]timduru[/MENTION] KatKiss rom 5.1.1 v30 release on my TF201, on which I was require to flash the grimlock kernel to make it boot on the TF201. Doing this since the v13 release or something. This rom still makes my TF201 the daily tablet I use. It could be faster and more stable, but still more than good enough for daily use and not to throw the hardware away. Thanks a lot for that!

This Marshmallow version does trigger my curiosity of course :) However it seems it doesn't boot on the TF201, so I assume the 'trick' could work again by flashing a different kernel after flashing this rom. There is however no Grimlock kernel for 6.0, only for 5.1.1 and I assume this 5.1.1 version will not work on this 6.0 android version.

I want to try and help to get this rom running on a TF201, but some help could be welcome :)

1/ Is it save to try the 5.1.1 Grimlock kernel with this rom?

2/ Any other kernel which could be tried?

3/ other options to get Marshmallow running an a TF201?

Thanks a lot!

Frank
[Transformer TF300T Android Development] gc2712:
I too have a question about using it on my TF700T as well.. I have installed it on my TF300 and am very pleased so far. I used to run Zombie-Pop 5.1.1 on both my TF300 and TF700 and could install to either machine with the one Rom and aroma installer, simply checking the option for which device was being installed to. So I would be very interested if there was a way to install this ROM on the TF700 as well.

Audio issues and bug in Clock app

When I try to select another time zone by clicking on the 'world' icon in the clock app, it just crashes. Clearing cache and data did not fix this.

Audio problems more serious. I am unable to get audio using Google Hangouts. It crashes when the call is connected. I can hear the other person for a second and they can hear me similarly but then crashes instantly. I tried installing K.A.T. audio, but that didn't solve the problem either. (Then uninstalled) As Hangouts is how I keep in touch with family this is important to me . Is there any workaround for these audio issues? I should add that it all worked with previous Lollipop rom, so not a hardware issue I wouldn't think. I should add audio and video work fine with eg Youtube or streaming radio.

And its great to hear about the TF700 development! Many thanks
[Transformer TF300T Android Development] purple patch:
Hi, I tried the new kernel. I was getting Wi-Fi cutting out, and then reconnecting (rekeying issue). Tried flashing kernel on top of current. Got auto reboots about 3 mins after tablet loaded fully. Did new clean install, went well through setup, but then auto reboots again. I'll just stick with issues, until I have time to go back to katt lollipop where everything works fine.
[Transformer TF300T Android Development] tjikko:
I'm just adding a small note

I started to get WiFi issues aswell, some random disconnects at first.

But a week ago the list of WiFi networks was empty. I could add manual networks and it kinda worked but I was not able to select anything as it didn't show any networks in the area.

Reboots didn't do anything and the kernel patch was not fixing it either. In the end it was fixed by a complete wipe and reinstall with only update 11 and now it all works again as normal.

Tim, kudos to you for working on this. I do think that ASUS made motherboards from at least three different factories. I live in China and know this happens. That means tracking down all these issues will be very tough since there are small differences in all the makes. If we all opened up our tablets and compared we would see three different colored motherboards. Its a bummer ASUS does this but so be it.

Thanks again for your hard work.

After a soft brick I have rebuilt my tf300t a few times from full format and changing file systems on data.

A major hurdle right now is the fact I cannot use my 2TB USB drive without a format. That's my stay in the woods movie player.

Other OS's see it, mixed results on playing vob files.

So far the only os that plays flawlessly is cromi.

If this could be corrected I could stay with it.

Right now if I need it a restore to cromi is needed and thus no f2fs unless another format.

It has to be ext4 for now...

Any ideas why this is an issue? Some drivers not there yet?

[Transformer TF300T Android Development] pastorbob62:
Yes, the data format does take quite a while. Good thing you didn't panic though. The first time I formatted data was way back on CROMBi-X as an alpha tester. I did panic and wound up soft bricking my tablet. Fortunately the developer patiently guided me through recovering which required going all the way back to stock and working forward again (thank you again sbdags). It was a nerve wracking lesson to learn. :p

I would recommend updating your TWRP to Kang's latest just to stay up on all of the latest features.
