Thanks Lucius, I'll give it a shot to see if it works. As an update, here's what's been going on the last few days:

1. Tried your suggestion of not implementing the certain tweaks in PMR. Still got a random reboot leading to a bootloop.

2. Tried reinstalling everything, but then not doing any PMR tweaks. Again got a random reboot after awhile leading to a bootloop.

3. I was going to try reinstalling everything, and leaving fsync enabled, but haven't gotten around to it yet. I'll first try doing everything all over again, but will try using hund's new kernel that you uploaded to see if that works

One other question, does it make sense that I need to rewipe and repartition my sd card every time I do a fresh install? I've tried not doing it, and I just get a bootloop everytime I do a fresh install. Sorry if that's a dumb question, but I'm trying to narrow down whether there's a chance that my sdcard is defective.

One other note, I got my TF700 very early, so maybe there's some fault with the earlier models that leads to this?
[Asus Transformer TF700] lucius.zen:
Naw I got mine as soon as it was released in the US. Mine was part of the first round of models released in NA. So the age of your device won't be playing into things.

I doubt PMR tweaks or disabling fsync causes the bootloop. It is most likely due to the older version of Hund's kernel not working well for you. Try the newer one before anything else. The newer version fixed issues that some people were having. I have not had any myself, so I did not bother updating, but that should definitely help out :)

You do not need to repartition your sdcard when doing a fresh install. You should wipe everything but you do not need to reformat it.
[Asus Transformer TF700] lucius.zen:
I have had all of those PMR tweaks enabled for a month and have never had an issue with the status bar dissapearing. None of the tweaks in this guide do anything that could change the way the status bar is working. An app, or something else you have done, must be the culprit. I honestly can't say I have ever had the status bar disappear on me. With these tweaks enabled or otherwise.
[Asus Transformer TF700] KinetiClutch:
no worries! Think I sorted it :)! Thanks for all the help!
[Asus Transformer TF700] nsharma2:
Thanks Lucius, I'll give it a shot when I get off work and have some time to work on this.
[Asus Transformer TF700] lucius.zen:
Awesome glad things are working out, sry I could not be of more help, that is an issue I have no experience with.
[Asus Transformer TF700] ronniereiff:
CPU2.sh is set up like

echo <1700000> > /sys/module/cpu_tegra/parameters/pwr_cap_limit_1
echo <1700000> > /sys/module/cpu_tegra/parameters/pwr_cap_limit_2
echo <1600000> > /sys/module/cpu_tegra/parameters/pwr_cap_limit_3
echo <1600000> > /sys/module/cpu_tegra/parameters/pwr_cap_limit_4

but in Antutu CPU it indicates while in balanced mode (or any mode in that matter) the max is 1900000. So will my CPU ever hit 1.9GHz? or not?
[Asus Transformer TF700] nsharma2:
With the new Browser2Ram init.d script, I no longer need to install the app through the CROMI installer? That small script replaces it?
[Asus Transformer TF700] lucius.zen:
Yep, no more Broswer3RAM app, the script has exactly the same effect. I would rather usea simple script to set B2RAM than an app.
[Asus Transformer TF700] lucius.zen:
The max is still 1900000 because that is the absolute max you can attain, if you have set CPU3.sh to do so. While in balanced mode my max freq is 1750000, although I am able to go up to 1900000 in performance mode. That max freq that is recognized is the highest freq possible, regardless of whether your profiles are capped below max freeq. When I am in balanced mode I am not able to go above 1750000. While in performance mode it is not possible for more than 2 cores to use any freq above 1850000.
[Asus Transformer TF700] ronniereiff:
Thanks I just needed reassurance that's what was happening :silly:

Should I replace 60tweaks found in your dropbox with cromi's 99tweaks?

Also have you thought about making a bloatware section for removing system apps/lib files?
[Asus Transformer TF700] nsharma2:
Sounds good to me!

FYI, I have run through your installation process again, with the only change being hund's new data2sd compatible kernel that you pointed me to. So far so good, but I'll come back and inform everyone later if that has fixed my issue.

Thanks very much for your help Lucius. I very much appreciate you taking the time to write the guide and being extremely prompt in your replies.
[Asus Transformer TF700] lucius.zen:
You should definitely use the script I have uploaded, it is modified to work congruently with my governor tweaks :)

I am going to absolutely have the bloatware section done tmrw. I put a lot of sections and video guides on hold bc people wanted to know what was happening with regards to 4.2. Now that everything has settled and I am sticking with 4,1 I will start to update these sections. Sry it has taken so long, I am currently packing up my entire room as I write this lol. When I am done moving it will be the tenth house I have lived in over the past 5 years....I just stated living in halifax 5 yrs ago. **** is insane. Since 18 yrs old I have essentially lived in a new home every 6 months in a city that is over 1000x bigger than the 70 person hamlet I grew up in. I know a lot of fools lol. Just let me know whatchu need son haha. Ridiculous.
[Asus Transformer TF700] ronniereiff:
Your pace on the guide has been perfect no need to rush and you're doing a good job (7300 kind of good) . Have a clean and safe move will yeah? :good:
[Asus Transformer TF700] lucius.zen:
Thanks a lot I realy appreciate the feedback.

Everytime somebody giives me fedback my guide literally gets 10% better. If I get good feedback I know what to emphasize and work on moving forward. If someone is hatin or having issues I know what needs to be improved. Regardless of the feedback it helps overall :). Please keep hooking me up. This thread is starting to collect enough data that it is a great place for people to learn how to tweak android in general, which was my goal with this thread in general.

This thread takes way more work than I thought, but it is evolving into the thread that I truly hoped to get going. A lot of people from very different backgrounds and experience levels are starting to share more than they used to. Which is more than I ever could have hoped for.

Ultimately what attracted me to android in the first place was the trajectory of its development. I was amazed that millions of people were working together to bring their devices to a higher level. Ultimately, if android continues to keep this spirit alive, no other mobile OS will be able to keep up in the long run. Apple and Microsoft are great, but they do not have a dedicated community like us.

I have never been a google fan boy. However, every day that goes by I am continualy impressed by our user base. Over the laung haul, it will be impossible for locked down operating systems to compete with our ingenuity.
[Asus Transformer TF700] nsharma2:
Another question for you. When I use Asus' stock file manager system (which I really like, so I installed it too), I noticed that it correctly interprets the locations of my internal storage, SD, and MicroSD cards. I was under the impression that data2sd would force the internal storage location to be my microsd card. Just want to make sure this effect is correct and that my data2sd mod has been implemeted correctly.

---------- Post added at 08:27 PM ---------- Previous post was at 08:14 PM ----------

And 5 minutes after I wrote my reply, my tablet randomly rebooted and is now in a bootloop... No idea what to try next. Assuming there is just some issue with my tablet or sdcard which will prevent me from successfully implementing the data2sd mod.

---------- Post added at 09:14 PM ---------- Previous post was at 08:27 PM ----------

Is there a recommended partition size for either the fat32 or ext4 partitions? I'm currently doing 32000mb for fat32, and whatever is left for ext4. Clearly I have a 64gb card.
[Asus Transformer TF700] buhohitr:
1) If you see 2 directories /sdcard and /sdcardi and /data /datai, you are running data2sd, Also download androbench app from the market and run check with "Micro" option and if the random write speed is 0.3mb/s or more then you're on data2sd

2) If you have 64gb, I would do 10gb for fat32 to store your backup/rom/kernel zips and what ever, the rest for ext4.

3) Try to bring back your normal setup either reflash cromi or from nandroid restore. After that flash _that kernel then let it boot up, then boot back into twrp then flash _that_data2sd.
[Asus Transformer TF700] nsharma2:
1. I see sdcard and sdcardi, but then I see data and data2. I think that's what you meant, so I'm good. Random Write is 0.3mb/s now (i left fsync disabled to experiment). Data2SD looks to be functioning properly.

2. I'll try that

3. What do you mean here? Don't I need to install mount-data2sd before I flash CROMI onto my machine? That's what I've been doing by following lucius' guide. I'm open to following other approaches if they might work.
[Asus Transformer TF700] buhohitr:
What you do is correct, you do need to flash mountdata2sd first.
[Asus Transformer TF700] nibblet787:
Just got through your awesome tutorial yesterday, then today I see that Pimp My ROM Beta has been released. And, sadly, it DOESN'T carry over any of the settings from PMR Alpha! Sigh, have to start all over again. :(
[Asus Transformer TF700] KinetiClutch:
Might be worth holding off. Read through his release thread and lots of people reporting issues!
[Asus Transformer TF700] nsharma2:
Update: Went through the same install process, but kept fsync enabled. Earlier today I got a bootloop again, so that did not solve the issue. I will try _that's kernel next to see if that helps.

I've seen some other posts that suggest disabling journaling can help with reboots/bootloops. I'm just not sure if that's already taken care of by the other mods I've been installing.

One other point: I've done a Nandroid backup, and when I restore that backup (after getting a bootloop), the device still gets stuck in a bootloop when I start it up. I thought restoring the backup would fix the bootloop temporarily. Maybe this is normal and expected, but my other thought is that my sdcard keeps getting corrupted somehow.

Thanks.
[Asus Transformer TF700] ronniereiff:
Ive had 2 fatal crashes that caused me to restore my back up but i cant understandy why. It seems it happens randomly. Is there a way to get the loggs and find the problem?
[Asus Transformer TF700] lucius.zen:
I just finished cleaning up the alpha PMR tweaks. I wanted to get a solid base to work from. The new version has some new tweaks. I am going to start testing the beta version now.
[Asus Transformer TF700] lucius.zen:
Restoring a working Nandroid backup should not result in boot loops so long as it is done correctly.

I am pretty sure journaling is disabled with Hund's kernel, I am not 100% sure. I checked in a terminal if it is enabled and no output came back.

Since buying a new 32Gb SanDisk UHS-1 SD card I have not had any issues with random reboots. I would not use a 64Gb SD card, I know people had issues with using them and D2SD in the past. I would send Buhohitr a PM or ask him about using 64Gb cards, he has been using D2SD for a long time and has helped more people use D2SD than you could shake a stick at. I am sure if you asked politely he would not mind helping you out, just be ready and willing to describe your issues in great detail.

To get logs after a random reboot you need to enter the following command into a terminal and save the output - last_kmsg.

See the following link for detailed information about accessing last_kmsg from unexpected reboots or kernel logs in general. See the last two sections at the bottom of the page - http://code.google.com/p/tegraowners-ics-rom/wiki/How_to_get_logs.
[Asus Transformer TF700] nsharma2:
Likely a dumb question, but if I'm using a _that kernel, I can't simply take your init.d script right? I'd need to write my own?
[Asus Transformer TF700] ronniereiff:
I believe the voltage table would have to many steps in it.

---------- Post added at 06:55 AM ---------- Previous post was at 06:09 AM ----------

So i reflashed tthe rom and replaced all int.d scripts with the one you have and the none data2sd kernel in your drop box. I also flashed the entropic mod or what ever it was called and the xloud thing. Thats it. Yet it still crashed after like 5-7 hours of smooth and cool use and bootlooped.

I'm going to leave int.d alone and see if it can last all night and tomorrow
[Asus Transformer TF700] KinetiClutch:
Had an issue on 4.4 whereby after doing the most internet and kernel tweaks I no longer could get internet access.

Just wouldn't get an IP
[Asus Transformer TF700] nsharma2:
I had that happen as well when I tried using a _that kernel, and then still tried applying Lucius' tweaks. Imagine it was my fault since I didn't completely follow his guide and tried to implement his tweaks anyway.

Ended up reflashing everything and skipped the PMR tweaks.
[Asus Transformer TF700] ronniereiff:
So far so good.. I'm convinced its the int.d scripts

Update: still running smoothly with no crash.
[Asus Transformer TF700] lucius.zen:
The PMR tweaks are a mixed bag with any 4.2 based ROMs, I would apply them one at a time and test thoroughly if you are using PMR with 4.2.

Just moving my stuff into my new place today. Almost done testing the beta PMR tweaks. Getting pretty awesome results so far.
[Asus Transformer TF700] lucius.zen:
Which init.d scripts in particular? I have been using my voltage table and kernel tweaks for a long time and have had no issues. In my guide I mention you may need to increase your voltages for higher frequencies if your CPU does not take well to under volting. Simply applying my 01ZenKernelTweaks may not work well, you may need to tweak the voltage table to suit your cpu. The voltage table is the most likely to be finicky between different devices. It is the only tweak that may not be optimal for every device. I should stress this more in my guide. I thought I did but now that I look at it I dont make this as clear as I should. I will update as soon as possible. I have a lot of things in the pipeline right now but moving is preventing me from doing any real work.

I will do some major testing of my governor tweaks to make sure they are not causing your random reboots. I have not had this issue so it may be difficult, but I will spend some more time looking at how these change cpu behaviour and how this might cause a hiccup. The voltage table you will have to work with on your own. I suggest starting by making small changes in the voltage table using android tuner, running some benchmarks and stress tests, then looking at cpu scaling and behaviour in android tuner. If things look nice and smooth like the graphs ive posten in the detailed results section, and heat is within a reasonable range, then you are good to go. After finding the optimal voltage table simply modify the init.d script i have provided with the new values. Implement it as usual. If you are not using android tuner I suggest doing so, it is necessary to make sure the 01ZenKernelTweaks script is actually applying properly.

Have you checked to make sure the voltage table and gov tweaks have applied properl using android tuner??
[Asus Transformer TF700] ronniereiff:
Amazingly it crashed again as sooon as i got home and bootlooped. I added no int.d scripts no pmr tweaks. Nothing unusual. I installed greenify and added nvision to too it and 20sec later it crashed.

I might just flash cromi-x to see if that fixes it. bbecause im scared the crashes are hardware related :/
[Asus Transformer TF700] nsharma2:
I was experiencing random reboots (leading to a bootloop everytime) and tried multiple ways to install using lucius' guide. I ended up using a version of _that's kernel, and so far it's the longest I've gone without a reboot & bootloop. Not saying it will stick, but I'm feeling good about it.

Maybe that will work for you?
[Asus Transformer TF700] bluntman420:
I also am having random reboots leading to a full system crash that can't be recovered. Have to restore a backup or start fresh. I have followed the guide to a tee and increased the volatge for 1900 to 1360mv as suggested. Any suggestions?
[Asus Transformer TF700] ronniereiff:
Which kernels did yall use? Was it data2sd ones or?
[Asus Transformer TF700] bluntman420:
Hunds 2.2 04/08. No data2sd. The tablet was getting really hot also.
[Asus Transformer TF700] ronniereiff:
I also had v2.2 none data2sd and got a crash and bootloop. As for heat i dont recall iit getting hot.
[Asus Transformer TF700] Hundsbuah:
please dont use the old kernels.they are not realy stable. upgrade to jb4.2 and use my kernel 3.0.5 with m app to cap the highest allowd oc frequency
[Asus Transformer TF700] KinetiClutch:
Ronnie. Just install the new CROMI and try that. Least you can start figuring out if its hardware or not! Stir you'd rather know than not know
[Asus Transformer TF700] ronniereiff:
You don't have any stable kernels for 4.1.1?
[Asus Transformer TF700] Hundsbuah:
hm not as stable as the new jb4.2 ones. what 2.2 kernel do you use? _20130410?

Gesendet von meinem ASUS Transformer Pad TF700T mit Tapatalk 2
[Asus Transformer TF700] lucius.zen:
The one that I have linked is 20130410 so most likely thats the one they are using.

I havent had any stability issues but now that CROMi-X has started to get updates and Hunds kernel is running smoothly I will check out 4.2 again. Just finished moving into my new place so I will have a chance to start working again. I have been out of it for the past week.

How well is the D2SD version of your kernel working? I won't use 4.2 unless the D2SD version is working well. I can't keep using my tablets internal storage, i am afraid of burning it out with all the testing I do.

Is it possible to implement the freq steps you used in v2.2 in v3.05? My voltage table and governor tweaks work really well with those freq steps. I would have to rewrite my voltage table and test new governor tweaks if I were to move to 4.2. That will take several weeks of testing and research that I would rather avoid. If the freq steps on your new kernel can be modified to be the same as v2.2 then I would switch to 4.2 in a heart beat. I still will, I am just a lot more reluctant lol.
[Asus Transformer TF700] lucius.zen:
Hey guys,

I am really sorry you have been experiencing issues and I have not been around much to help out. I just finished moving so I will start looking into it. I have been going through my tweaks but none of them should be causing random boot loops. Considering it still happens when you remove the PMR tweaks, my other kernel tweaks, and with both D2SD and regular kernels it must be a bug in Hund's old kernel. Which is weird, bc I have not had any random reboots, but it could not be anything else. I am going to take a look at getting my tweaks to work with Hund's new kernel and 4.2 so that you guys who are having issues with 4.1 and the old kernel have something to work with.

All the best,

Lucius

PS - Thanks for giving these tweaks a shot, I am really sorry they have not worked out for all of you. I will do my best to get these working for everyone, so we can all have badass performance, regardless of which version of android we are using.
[Asus Transformer TF700] Hundsbuah:
the cpu sacling was really fine when i rewrote the dvfs table. with asus stock settings the scaling is not so great and smooth. but rewriting means a lot of testing and its time consuming.

i use data2sd in jb4.2 with my kernel since 2 weeks and no problems so far. runs really great!

[Asus Transformer TF700] KinetiClutch:
Hund what do I need to do to get Data 2 SD working with your kernel?
[Asus Transformer TF700] lucius.zen:
Cool I was just curious why the freq steps had changed, considering I was getting such amazing results with them, I figured you would keep them haha. That sucks they do not work easily with 4.2.

Do you plan on trying to rewrite the dvfs table in the future? I realize its a lot of work, so no rush, I am just curious more than anything. If we stick with the freq steps that Asus uses it will be impossible for me to get the cpu to perform as well with 4.2.

Up until v2.2 I had hit a plateau in my performance. I was honestly starting to believe my tablet was not capable of running the GPU above 750Mhz and the CPU above 1.8Ghz. The dvfs table in v2.2 is unreal. Voltage table and governor tweaks are much more effective with those freq steps.

Ill try and learn more about dvfs tables and kernel compilation in general so I can be more help.

All the best,

Lucius
[Asus Transformer TF700] lucius.zen:
You need to flash the D2SD patch included with Hund's 3.05 kernel after flashing your new kernel, I beleive.
[Asus Transformer TF700] Hundsbuah:
just flash the kernel zip archive in twrp and after flashing the kernel (you dont have to reboot after kernel flash) you flash the data2sd patch zip file (also on twrp, some procedure as flashing a kernel)

yes i think ill rewrite the table when i have time. as the tf300t are now on a sperate project and seperate sources its much easier to rewrite the dvfs table just for a tf700t device.

[Asus Transformer TF700] lucius.zen:
We definitely have a lot of work to do lol. See what i mean - http://db.tt/3NXeHAO3

Scaling is really bad.

Heat is actually good considering the inefficient scaling. GPU performance is a little weird. I am only getting 40fps during 2d graphics tests rather than the usual 50fps. I am getting bad results on the second 3d graphics test in quadrant. Instead of a steady 60fps it jumps from 35fps to 40fps. Everything else is fine, still getting browser shut downs if i try to use shift+backspace.
[Asus Transformer TF700] Boerseun23:
This guide helped me to actually move away from data2sd. I am getting over 7000 points on the i/o quadrant benchmark and no lag on keyboard or browser. Its just awesome. :)

---------- Post added at 07:56 PM ---------- Previous post was at 07:50 PM ----------

Only issue I have is voltage seem to high for 1.9ghz so i only use 1.75ghz. Still notice the top left hand corner of the tablet getting luke warm
[Asus Transformer TF700] lucius.zen:
Glad my guide has helped thanks for the feedback :).

Luke warm is approximately 22C-36C. You should do more exact measurements. A solid operating temp is between 33C and 45C. Up to 55C is safe, safeguards are buit into the cpu to shut things down when core temp goes into unsafe territory. When using 1.9Ghz I still sit between 34C-50C, usually never more than 45C.

If you are getting heat in unsafe ranges you could drop 1.9Ghz to 1340mV and 1.85Ghz to 1310mV.

I also cannot recommend my tweaks if you do any gaming, I have never tested any games on my tablet.
