_that v7 configuration switch

Hi all,

I install latest version of Cromi-x (by the way, excellent as previous one), and select _that v7 kernel with clock up to 1.8GHz. I'm wondering if there is a "rapid" way to modify this to use the 1.6GHz max instead as proposed during installation ? Any script to launch ?

I know it is always possible re-installing other the current installation, but it is very long process.

A second question, that is somehow closed to the previous one would be: is there is a way to select a different kernel without doing a complete installation ?

Thanks and Merry Christmass
[Asus Transformer TF700] lartomar2002:
sbdags, would it be possible to include "dynamic fsync" with the next rom for those of us that do not use hund's kernel? Or, is it a kernel only function?
[Asus Transformer TF700] butcherbird:
+1

Or, maybe Hunds can share it with _that?

I'd like to know that, if I decide to switch back to _that sometime, I have the same security in place.

Thank you all! :)
[Asus Transformer TF700] _that:
All ways of turning off fsync violate the contract between apps and the kernel. I am not convinced that "dynamic fsync" is safer than turning it off completely.
[Asus Transformer TF700] sbdags:
It takes about 5 mins - just reinstall and choose the same options - you don't have to reset anything else up as dirty flashing keeps all your apps and date ;)
[Asus Transformer TF700] nevertells2:
Thanks!!! :laugh: That makes good old plain sense. Guess I am a fairly conservative kind of guy and don't want to risk the corruption, data loss and other consequences of messing around with fsync.

---------- Post added at 06:49 PM ---------- Previous post was at 06:45 PM ----------

Did you guys read what _that previously had to say about dynamic fsync? I believe Sbdags only includes the kernels, not write them.
[Asus Transformer TF700] JBT1:
OK thanks, was just wondering ;)
[Asus Transformer TF700] Mackis:
Hi Sbdags. You and Hundsbuah have surprized me again. Running the latest build with Hunds kernel and this is blistering fast. 7062 is the quadrant score i get.

Once again THANKS for all the work boys you are simply awesome!!

I received a couple of 64GB Sandisk Ultras for Christmas and decided to jump into the Rom2SD waters. Wow, what a difference! I even left fsync on and feel like the tablet is plenty fast enough in comparison to its native state.

Many thanks to all the people who worked to make this work on this tablet along with CROMi-X. Together, CROMi-X and Rom2SD is a perfect combination.

Again, WOW!
[Asus Transformer TF700] tiernan22:
Let me know how it goes with the Sandisks. I picked one up too about a month ago and my system partition corrupted twice after a couple days on rom2sd.
[Asus Transformer TF700] thefezzer:
I seem to be having the same issue with a 32g Ultra. :( The first two tries were in data2sd, this is the first try with rom2sd. I must say, when it does work, the tablet is just stupid fast.
[Asus Transformer TF700] butcherbird:
I'd missed _that's previous comments, but I see what _that wrote just recently. I'll leave the why's and how's to better pirates. Haarrr!
[Asus Transformer TF700] sbdags:
What tool did you use to partition it? I also recommend leaving fsync enabled. You don't really need it for rom2sd or dats2sd.
[Asus Transformer TF700] tiernan22:
I used GParted Live. I haven't gotten a chance to repartition it yet but perhaps I will tomorrow. In all fairness, you've made it far to easy to fall back on my internal. :highfive:
[Asus Transformer TF700] thefezzer:
I, too, love the instant fallback. Is there a meaningful reliability advantage to having fsync enabled? Is that a possible culprit to my issues with the device bootlooping?

Also, thanks for all you do, sbdags.
[Asus Transformer TF700] sbdags:
Yes quite possibly - if the device crashes or reboots unexpectedly then it is possible your data partition can become corrupted. This seems to happen much easier on the sd card than on the internal partition. I don't recommend fsync disabled if you don't understand the risks. I have corrupted 3 times now (all internal) - admittedly I'm probably flashing more than anyone else here and testing stuff all the time but still it can and may happen. It could also corrupt something that you don't use so you may not realise for a while or until that part of the data partition is used.

Since I reformatted my internal card and stopped OC'ing I have not corrupted at all for the last 2 months. I use fsync disabled (for testing purposes obviously :) )

Always have a recent nandroid backup to fall back to and I recommend scheduling backups with tibu - that way you can always get back without too much effort if you do corrupt.

Remember we are pushing our devices beyond what they were designed for - 5.2.3 seems to be the most stable for me though :good:
[Asus Transformer TF700] thefezzer:
As this is a desperate attempt to get the performance we paid for out of these tabs, I think we're pushing the tablets /to/ what they're designed for. ;) I've had no fc's or anr's on this new kernel in the sd, but time will tell. With fsync enabled, it posts 6100 on Quadrant, which is okay. I think I'll just watch to see if the user experience is up to snuff.
[Asus Transformer TF700] _that:
(micro)SD cards seem to be unreliable throughout, especially on the TF700. I remember there were severe reliability issues in old (ICS) kernels that Asus worked around by reducing clock speeds below their nominal values, also UHS-I doesn't seem to work with the rated maximum speed. This looks like a hardware issue.

All those interoperability issues tell me that either the MMC/SD spec is not strict enough, or the implementors don't care enough about the spec (and can get away with it).

In addition, the flash translation layers embedded in the cards are much less sophisticated than those on real SSDs - some of them are even optimized for running FAT only. Manufacturers only specify maximum sequential write speed and capacity. And there are no real reviews that measure the performance and reliability of these cards as an OS drive. I'd like to see flash cards reviewed as thoroughly as SSDs, e.g. by AnandTech.

If anyone wants to know how flash cards work internally, read this: https://wiki.linaro.org/WorkingGroups/KernelArchived/Projects/FlashCardSurvey

Perfomance switch ?

Hi,

I remember that stock ROM and even Cromi-X 4.1 UI, when opening the notification tray, there was a switch to move from the 3 performances mode.

I move to 4.2 UI and Asus performance swith has diseaper. Is there a way to make it re-appear ? Or does anyone know a widget that could be placed on the desktop to move from "normal" mode to "balanced" or "saver" mode ? Currently I have to go to parameters, Asus property and select the performance mode which is a lot of screen and actions.

Another remark from the Wifi switch in the notification tray, it does not enable/disable the wifi but open the Wifi parameter screen instead. Is it expected ? I remember that it was enabling/disabling wifi with 4.1 UI.

Thanks
[Asus Transformer TF700] sbdags:
You are going through what all of us do with 4.2GUI. Basically Asus never added any of their tweaks and never even enabled it on the TF700.

You can enable some functionality with the xposed modules I included but most of us go back to 4.1.
[Asus Transformer TF700] JBT1:
Too sad :( I like the position of the buttons in the bottom bar...

Any chance to get the UI from theTF701 ?

Do you have a module to recommend from xposed ?

Thanks
[Asus Transformer TF700] acraigl:
I'm staying with the 4.2 UI, I just like it better. I was annoyed at first, but in practice, I found that I really don't switch speeds all that much. There's an app called QuickShortCutMaker, that can give you access to the specific setting quickly from the desktop. I made one for 'Performance' and 'Display' (for IPS+ mode).

I really don't miss 4.1 at all and I don't find the 4.2 launcher to be laggy since the more recent Chromi/Kernel combos.
[Asus Transformer TF700] sparksd:
In QuickShortCutMaker, what are you shortcutting for "Performance"? I assume you mean changing performance modes but in QuickShortCutMaker it appears that you can only create a shortcut to bring up the entire "Asus customized setting" menu from Settings, not the performance subcategory alone. I'd like a shortcut that simply brings up a selection of performance modes only.
[Asus Transformer TF700] JBT1:
Thanks, sound's good.

I install it but can't find the direct acces to "performance". I see the access to the Asus parameters pannel, is it the way your doing ? It is already some actions less :)

Since we're talking about memory cards, I was gifted a pony 128 gb sd memory card. It won't work on the tablet, but it will on my computer. I formatted into fat32, but that was a no go. Any suggestions?

[Asus Transformer TF700] Jettubby:
Hey guys why is this tablet always so slow after it wakes up? Every Rom and every kernel is the same. It's like it never fully wakes up and I always have to reboot to get it going? What the.......? Frustrating
[Asus Transformer TF700] acraigl:
Sorry guys, I see how that sounded more magical that it actually is. My "Performance" shortcut is simply access to the Asus Customized Settings where I can access the system performance setting. It's only a click or two savings, but it is what it is. Sorry if I made it out to be more than that in my previous post :o
[Asus Transformer TF700] berndblb:
If it is the same on any kernel and rom and nobody else complains about it - could it be your setup?

Do you have the same behavior before you restore your apps, launcher, widgets etc?
[Asus Transformer TF700] sbdags:
Both of your problems are particular to your setup. Lookup how to get a logcat here on xda and grab one. It will help identify where your issues are.

Failing that I'd try a full data partition format in twrp and clean install to eliminate other issues.
[Asus Transformer TF700] nevertells2:
Your card is too big. TF700 will read up to a 32GB SD card.

Is it possible he meant the SD card in the dock, not the microSD in the tablet itself (he mixes tablet & SD together)? I also use 64GB microSD in my tablet (formatted NTFS) and a 64GB SD card in my dock.
[Asus Transformer TF700] johnnytraveler:
Sorry, let me be more specific. SD card in the dock. The tablet sees it when it is docked, but can't read or write to it. Yet I can with a computer.

Bootlooping

Hello

I wonder if you could give me some advice I am new to rooting - so inexperienced (so why did I install a ROM ... of course because the TF700 is so laggy I could not take it anymore!!)

I was using CROMIX 5.1 and everything was ok - and so much better than standard rom!

I updated to 5.2.3 and everything seemed ok.

The tablet TF700 was working with no issue.

I switched it off and when it rebooted it got stuck at booting with the circular dots 'spinning' round and round and never starting.

I got into the recovery mode and cleaned dalvik cache... issues remained.

I then reinstalled the ROM from zip in recovery mode. The issues remained.

I have recleaned dalvik cache / fixed permission / cleaned cache partition ... still stuck...

What would be the next step - do i need to do a full whipe and start again?

Anything else I should try?

Thanks for your help

M
[Asus Transformer TF700] sbdags:
Can you capture a logcat using this guide please as it is stuck on the bootlogo and we need to know why.

To fix your issue - you probably need to format data. You can do a backup in TWRP first, in the TWRP wipe menu slide the wipe button and then either reinstall the rom - you will lose all your apps and data or restore your backup.

If that doesn't work then in the wipe menu you will need to format data - hit the format data button. This will wipe your entire internal SD so make sure you save photos, music, etc that you want to keep.

Let me know how you get on please. BTW which kernel were you using and did you disable fsync?
[Asus Transformer TF700] sbdags:
You had a previous installation and did not uninstall it cleanly. You need to remove the tibu entries in /data/data and then it will reinstall again. The most common cause of this is using cache2sd. You can unmount cache2sd by issuing the cache2sd -u in terminal window.
[Asus Transformer TF700] ghislandi:

Sorry again for stupid questions...

I don't have the tablet with me... I followed the wizard and only changed the dpi and put on us built....
[Asus Transformer TF700] ntunix:
Does anyone here notices significally advantages in using ROM2SD or even DATA2SD on the latest ROM with fsync on? I wanted to get a sandisk extreme micro sd (80MB/s) but bought a sandisk ultra (UHS-1 30MB/s) instead as it was recommended here in the post. But this card shows little to no advantages at my eyes... the tablet doesn't feel snappier at all, not with ROM2SD and DATA2SD or just with DATA2SD. I'm just wondering if it's just me or if maybe I should had bougth the extreme card.... I used thatv4 and thatv7 kernels for testing.

Btw, android app Sdcard tester shows average of 8MB/s write and 28MB/s read speeds.

Stuck after reboot

Hi Guys,

Thanks for all the work that's gone into these ROMS, while I've messed about with different ROMS in the past, I've never used ROM2SD before. I bought a Sandisk Extreme 16GB to try and make the Infinity more usable, partitioned it with GParted and run through the installation scripts.

After the tablet restarts, it gets to the line;

system/boot/preinit: mmcblk1p3 detected, setting up for ROM2SD

and hangs, how long should this step take?
[Asus Transformer TF700] sbdags:
Unfortunately the SanDisk Extreme is not compatible. :(
[Asus Transformer TF700] RexNoctis:
Ah, that's a shame but thanks for the info.

I have a normal Samsung 32GB but it's not particularly fast. What is the fastest compatible card and what should I be looking for to ensure something is compatible?

Cheers
[Asus Transformer TF700] nevertells2:
My bad, I thought I read that it took up to 32gb.
[Asus Transformer TF700] sbdags:
I have a 32GB and a 64GB SanDisk Ultra Class 10 - UHS-1 card and both work fine.
[Asus Transformer TF700] geri.st:
i am facing a similar issue,

after installing 5.2.3 the first time, everything went fine, when i rebooted i stuck on bootloop. after reinstalling 5.2.3 i got stuck on "starting apps"

i am not at home, so no pc to pull a logcat.

any update on this?
[Asus Transformer TF700] berndblb:
I have used a 8 gb ScanDisk SDHC class 4 to run miniC as ROM2SD and that was just fine - except it's too small, so I now use the ScanDisk UHS-1 class 10 everybody else has.

Get a good quality card. That will make more of a difference than class 4 or class 10.

I tried the Extreme too but it does not work for ROM2SD with the TF700 :(

DATA2SD vs ROM2SD

OK guys, quick question or straw poll on which would be quicker;

1/ DATA2SD on SanDisk Extreme (~80MB/s) with data on card and system on internal memory

or

2/ ROM2SD on SanDisk Ultra (~30MB/s) with both data and system on card.

Can the Infinity even use the extra speed of the Extreme card?

I'm currently running option 1, wondering if it's worth buying an Ultra card in order to use ROM2SD?

Thanks again,
[Asus Transformer TF700] butcherbird:
Does ROM2SD work using microSD cards? Or, does it have to be a full-size SD card? The microSD is a lot harder to accidentally remove, imho.

Is there an official consensus yet on which card is best to use for ROM2SD? I see bernd's comment about SanDisk Class 10 UHS-1 (not Extreme version).

Thanks.
[Asus Transformer TF700] _that:
It's designed for using the microSD card, for exactly this reason. It would suck if your tablet crashed every time you undock. :)
[Asus Transformer TF700] sbdags:
The Extreme won't work as DATA2SD or ROM2SD. For some reason it doesn't like EXT4 partitions.

Just quick question, if I want to start using rom2sd will I need to do a clean install/factory reset? I'm currently quite happy with my CROMI-X 5.2.3 install, so if I need to reinstall everything might have to think twice haha. Speak volumes about the quality of CX5.2.3 though!

Nope, it's totally separate installation. And if you want you can make a nandroid of your current setup and restore it to the ROM2SD installation ;)

OK, I'm running DATA2SD on the Extreme at the moment, ROM2SD would not work. I will keep DATA2SD on there until my Ultra arrives. I can't see why one would work and not the other, it has three partitions Fat32 (1024MB) / Ext4 (~14GB) / Ext4 (1024MB).

I put the Extreme micro SD into my S3 and bought a Sony 40MB/s, faster than the Ultras and works a treat. :)
[Asus Transformer TF700] sparksd:
Apologies if this is covered in the thread but I couldn't find it. With ROM2SD and DATA2SD installations, what exactly ends up on the microSD after installation? After installation, is the internal memory still used, i.e., are apps installed there or on the microSD, is internal memory available for file store, etc?
[Asus Transformer TF700] sbdags:
ROM2SD - full rom is installed on sd - so that is the system and data partitions ;)

DATA2SD - only the data partition is installed to SD (so installed apps, app data and settings, preferences etc). System remains on the internal SD.

On both the internal data partition is still accessible but is not used by the system. SO you can transfer stuff or store stuff on the internal SD still but most apps won't see it unless they have an option to share a folder somewhere - file explorers do for example.
[Asus Transformer TF700] acraigl:
I'm pretty happy with the standard installation, but everyone is so gaga over this ROM2SD thing, that I'm going to give it whirl today.

Currently, all my backup data (TWRP, TiBU) is on the external SD and all my media (videos, music, etc) is internal. Should I reverse this for the ROM2SD install, or is that something that I don't have to worry about? I took a nandroid already, so not too worried, but any planning I should be thinking about with the change?

OK, so I did it :)

Any way to restore my previous nandroid to the the ROM2SD partition?
[Asus Transformer TF700] berndblb:
Make sure the nandroid is on the microSD (fat32 partition)

Boot into TWRP, flash rom2sd1 to orient TWRP towards the rom2sd installation.

Restore the nandroid.
