It's not the regular GRIMKERN 2.2RC you're talking here, is it? I tried it yesterday: Did a backup with Philz CWM, wiped Cache/Dalvik then flashed this one. Got bootloop.

Curious: Restored the b/u, still bootloop.

Did a clean flash: newest SlimKat (RC 1 3.6), GrimKern 2.2 RC1. Bootloop.

Clean flash: Slim, GEASS, now it's working.

I'm no expert by any means but have been doing quite a bit of flashing during the last 3 years, Did I do something wrong? Especially the bootloop after restoring the backup had me flabbergasted a bit.

If you somehow compiled GrimKern to your needs - is it o.k. for you to post it here? Would love to try this one ...

Can't wait to see a new weekly btw :) :laugh:
[Transformer TF300T Android Development] ne0zone75:
Hello, did you wiped cache / dalvik AFTER having restored your backup ?! If so, i do not see any reason for the bootloop to remain after your backup is restored :confused:

Anyway official GRIMLOCK v2.2RC can work out of the box but only a few users have reported it to do so... most of the time you'll get bootloop or SOD's...

To summarise i would say that you did nothing wrong but you may have forgot the cache / dalvik wipe after restoring your backup...

Yes i am using a private build of GRIMLOCK v2.2RC but it is basically the same as the official one and i'm issuing some SOD's but no bootloop ! If you really want to try it, i can ask [MENTION=2158597]hardslog[/MENTION] the permission to make it available for download in this thread :D

Or you can wait for an official update of it...

And you are right, GEASS v6 is running really great!

BTW SlimKAT RC1 build 3.8 is compiled :good: It's currently uploading ;)

SlimKAT for TF300T RC1 build 3.8 is available for download !

Download links are now updated !

Enjoy and don't forget to report back please...

NOTE : There is no changelog today on my side because there is nothing new... i'm working on dock battery display status ATM and i'm progressing slowly :p So this release is a SlimKAT weekly update like our device was officially supported :good:
[Transformer TF300T Android Development] hardslog:
No need to ask for my permission. GRIMLOCK is full GPL. Do what you wish with it :P

By the way, the only common occurance I have of people not being able to get 2.2rc working is that they are using Philz recovery...... Seems odd if that would be the culprit though.....
[Transformer TF300T Android Development] ne0zone75:
Hello and thank you so much for your answer hardslog :good: In addition i would like to say that when flashing v2.2RC on my setup i must never do not wipe cache / dalvik once your kernel is installed otherwise i'm beginning to get various FCs and some SODs... i don't know if it's related to ART turned on; ATM i'm running it on build 3.8 released a few moments ago and it's working perfectly well :D

So i will make my flashable .zip file of your kernel available for download ASAP !

Thank you again !

Custom GRIMLOCK v2.2RC kernel with NFS/CIFS support !

So my own build of GRIMLOCK v2.2RC1 kernel by hardslog is now available HERE for the kernel (flashable .zip file) and HERE for its .md5 :p

CAUTION

: TO AVOID TO GET INTO PROBLEMS WHEN FLASHING IT PLEASE FOLLOW THE STEPS BELOW... THANK YOU ;)

=>TO BE ABLE TO FLASH SECURELY THIS .ZIP FILE YOU MUST COME FROM CM KERNEL (which is inside my SlimKAT ROM .zip file). If you're coming from GEASS please switch to CM stock kernel first by the way of your choice !

=> ONCE KERNEL IS FLASHED, IF YOU WANT TO SWITCH TO GEASS / CM KERNELS PLEASE RESTORE YOUR NANDROID BACKUP FIRST AS DESCRIBED BELOW ! Thank you !

-> Perform a full NANDROID backup before doing anything else !

-> Flash the .zip file from recovery (TWRP HIGHLY RECOMMENDED, Philz CWM users may encounter issues by flashing it ! See hardslog's post just above... thank you !) :fingers-crossed:

-> Reboot straight into system after flash is done WITHOUT wiping cache / dalvik !

-> DO NOT NEVER EVER WIPE CACHE / DALVIK ONCE THIS KERNEL HAS BEEN INSTALLED OR YOU MAY BEGIN TO GET FCs and SODs ! (needs confirmation)

Enjoy :highfive:

INFO : THIS ENTIRE POST IS OBSOLETE BECAUSE GRIMKERN v2.2RC3 IS OUT and works really nice on SlimKAT RC1 build 3.8 out of the box : no more bootloops & SODs :good: It is very fast and stable for me so far :p => Please check hardslog's GRIMKERN thread HERE if your interested in it, Thank you for reading this ;)

Exelent Work My Friend.!you rom work is very smooth and fast / whats diff you kernel and previews?

I am in 3.8 Twrp And original GL 2.2
[Transformer TF300T Android Development] ne0zone75:
Hello and thank you ! I'm glad you are enjoying it ;)

My GL v2.2RC build differs from official hardslog's one by adding NFS/CIFS support to it and kernel compression is LZMA instead of GZIP. I agree that these differences cannot explain why my build is not leading me into bootloop like the original does but mine is working perfectly fine for me on 3.8 :D

As GL v2.2RC issues origins are not clearly identified at this point, if it is working for you i do strongly recommend to stick with your current version :p

Is official one working great for you on 3.8 ?

All the best

TWRP 2.7.0.0 for TF300T UPDATE (now supports dock sd card)

Hello all, updated TWRP 2.7.0.0 for our beloved TF300T is now available for download :p i've just added downloads links for it; previous ones remain because i've not tested the new release WITHOUT using the dock. Please report back if you want to !

You can download the new version HERE for the flashable .zip file and HERE for its .md5 :highfive:

It features a significant update

: NOW YOU CAN USE DOCK SD CARD AS EXTERNAL STORAGE :good: like internal microSD one -> your SD card MUST be FAT formated AND if it does not mount automatically in TWRP, you can use the 'mount' menu in TWRP and select the corresponding entry by clicking on it ;)

Enjoy :D

EDIT : 2014-03-20 => New build is out and ready for DL :victory: It's built from today's synced TWRP sources from OmniROM GitHub tree and corrects some minor bugs : you can checkout changes HERE :p OP and above download links all updated, they are linked to most recent build !

Hello, RC1 build 3.9 is currently compiling, it will be available for download soon ! :good:

As usual you can dirty flash it over the previous build BUT for everything to be working please install official SlimROMs GAPPS (AIO or minimal package)... thank you ;)

ATM i'm still slowly progressing on adding dock battery display status feature to SlimKAT for TF300T : considering poll results it will be added added someday BUT because it is very time consuming it will take sometime... stay tuned ! :p

Here is the build 3.9 changelog from SlimROMs website :

I believe I am on bootloader 10 6 1 15 3 running omni but I have read through this thread and hear great things about slimkat I want to give a whirl.

I read in op I would need 10 6 1 27 5

Can I flash the new latest bootloader in twrp or do I need to fastboot the latest. I'm out of town and DONT have PC with
[Transformer TF300T Android Development] DoughMucker:
Hi,

I just bought a used tf300t and sometimes find it painfully slow compared to the tf101 I already own with Kit Kat (KatKiss) on it. From what I can determine by my use and what I have read this is probably due to I/O issues on the tf301t.

I'm going on holidays in a couple of days and don't have time to backup, flash, and restore before I go, but am going to when I get back. In the meantime, will SlimKat on it's own eliminate much of that lag or is inverting the install also required? Similarly, would flashing a kernel also help with that lag or is SlimKat enough on it's own?
[Transformer TF300T Android Development] ne0zone75:
You can try this : leave the bootloader as it is ;) Because if you're decided to give SlimKAT a try, coming from Omni then you'll certainly do a full wipe after having performed a full NANDROID backup; So you can try to use 10.6.1.15.3 BL instead of 10.6.1.27.5 AND if you cannot boot with 10.6.1.15.3; you can still upgrade it later when you'll have a PC with an Internet connection from which you can 'fastboot flash staging... your TF300T in order to upgrade the bootloader ;)

To clearly answer your question : It's strongly not recommended to flash only a bootloader image file thus it's possible via TWRP (or any custom recovery) BUT you can try skipping the bootloader upgrade part of my OP if you can be sure that you are running 10.6.1.15.3 (device off : push vol - and power on untill screen is showing you the three BL icons -> 'RCK', 'Android' AND the 'NEVER CLICK ON ME ONE' :p Then, on this bootscreen, your bootloader version is printed upper left on the screen !) If you're running a bootloader version previous to 10.6.1.15.3 THEN YOU WILL NEED TO UPG IT ! If your current BL is 10.6.1.15.3 there will be a chance that SlimKAT do boot with it :fingerscrossed:

Good luck !

I did my volume power button (s) trick and it did say what I previously posted (10 6 1 15 3).

I will do as suggested and let you know.

I have to say...As I read throughout your thread and op. ...YOU are frkn on the spot and very detailed about whatever situation anyone has and WANTS to resolve.....or guides them in a great direction (as you did with me) VERY IMPRESSIVE. ....had to say that!!!!!!!!

Now.....I will get back and update on how it's going....THANK YOU !!!!!
[Transformer TF300T Android Development] ne0zone75:
Hello, when acquiring a previously used android device, it is always good to format and i'm saying FORMAT again (not wiping) all your device's partitions from custom recovery ;) AFTER having done a full NANDROID backup !

You are right => I/O is a bootleneck on TF300T that's why ROMs featuring ROM2SD / DATA2SD like recent CROMBi-kk one are so fast because with a class 10 microsD used as system storage, ROM will be really faster than another using traditional slow TF300T internal NAND one (for the I/O part)

Stock SlimKAT (with embedded CyanogenMod kernel embedded into the installer available for download on post number 1) will BE : STABLE, FAST with GOOD BATTERY LIFE on its own BUT don't expect to get delirious benchmark results with a non OC kernel (like GEASS / GRIMLOCK) !

To limit I/O bootleneck on TF300T, you can try my SlimKAT Power Pack available for download in post number 2 (2 init.d scripts in it can make things better regarding I/O performance); it's not reserved to SlimKAT users BUT your TF300T must be running a ROM with init.d support (if you are unsure, you can download 'pimp my rom' app from Google Play and then check your init.d status with it... you must be root to use this app)

Sent from my TF300T
[Transformer TF300T Android Development] DoughMucker:
Yeah, I only did a wipe and not a full format. I have rooted and ran lagfix, but don't see too much difference. It's only at times when reading/writing to the sdcard is occurring that I notice it.

You mention stability, speed and battery life and that is why I am looking at SlimKAT. I don't need super benchmark scores, so I don't think I'll invert it, but my try a bit of overclocking.
[Transformer TF300T Android Development] ne0zone75:
If it's not stock ROM AND if 'pimp my my ROM' free app says that your current one is init.d enabled THEN my answer is yes :highfive:

[Transformer TF300T Android Development] MrsColumbo:
Cool

Works very good. Very smooth experience.

This is most probably off topic but I still have problems with TWRP. Split screen again ... maybe Philz CWM is the culprit. If i may ask: To change recovery you just flash a new one, don't you? Or this there any erase action required that I'm not aware of? I remember that TWRP worked before I changed to Philz recovery. Hm ...

And - again, this could be me - I always lose root, have to flash SU manually.

And (bear with me please :cyclops:) the combination Slim (newest as of 26th) with Geass (also newest) had insane battery drain - I always disable the usual suspect like FB, Mail and WiFi network scan, so it can't be those.Ah .. got SODs from time to time.

Slim without any custom kernels just works as intended.

Just 4 info.

I tried the KK Cromix (to have a bit on the side lol) - very nice and all, but I think Slim is my daily contender. I guess I have to iron out the mistakes I probably made in the course of installing hundreds of ROMs during the last years :angel:

Since I'm a magazine editor I need something that can be used for day to day routine when I'm not in the office (Basecamp, Drive, Dropbox, audio recording and transcribing these into articles and such, you know the drill), and Slim really fits the bill.

So: Thanks a lot for all the hard work - I really appreciate this!
[Transformer TF300T Android Development] ne0zone75:
Well.... thanks a lot for your post :good:

-> For your TWRP issue please try to flash the recovery.img file directly to your device using fastboot :

sudo fastboot flash recovery recovery.img

from a Linux terminal ;) after having extracted it from my flashable .zip to the directory of your choice... for Ubuntu based distributions you can install Android tools like this :

sudo apt-get install android-tools-{adb,fastboot}

If you are using Windows you can PM me I'll send you a mini howto...

-> For root access embedded Superuser is working BUT you have to activate it ! => for a fresh install go to 'developer options'' in settings menu and set it OFF (upper right toggle switch), then go to 'advanced options' / 'Superuser' and set it to ON using 'app +adb' mode (settings menu for Superuser is available from the 3 tiles upper right of your tablet screen). Then root access will be enabled :D

FYI it seems that is the way Philz CWM is flashing the. zip file that may cause your issue... you are not doing anything wrong :highfive:

In my opinion your post is not off-topic... anyway feel free to PM if you need further assistance...

[Transformer TF300T Android Development] MrsColumbo:
thx mate! Thing is ... I did fastbootTWRP to avoid any flashing issues - no difference to flashing from recovery, still splitscreen.

Next thing I will try (when there's time; I really really need a vacation) is a complete factory re-set-up. maybe I borked something with Philz or before.

Anyways - Philz works as intended so flashing TWRP would be a mere "cosmetic" thing - I like the look better :)

I don't really care 'bout the Kernel issues. I only miss being able to turn off FSYNC - I seem to notice some additional awesomeness smoothness-wise. I don't really OC the tab - that's what I have my Nexus 4 for - noodling around with different ROMs and kernels - an old mans toy, so to say.

I don't want to miss out mentioning this: I'm absolutely positive these issues are not in any way related to your ROM
[Transformer TF300T Android Development] ne0zone75:
What APP are you using to set kernel settings ?! Check out Trickster MOD if you are not already using it ;) For the battery drain you're experiencing... is it huge ?! Because GEASS kernel is usually battery friendly with SIO as I/O + smartASSV2 as governor :good:

Yeah I got Trickster. Will try with the settings you suggested ... thx again mate

Hello and welcome ;) FYI SlimKAT is CyanogenMod based (i mean its TF300T version here because device and kernel sources trees are coming from CM... otherwise original SlimKAT ROM is straightly AOSP based ;)) and AFAIK network geolocation is not working on CM for TF300T... please correct me if i'm wrong... so it doesn't work neither on SlimKAT BUT GPS is fully functional :good: Give a try to 'high accuracy' mode for geolocation it doesn't drain the battery too much and it uses GPS in addition :D
