Does stock have an fstrim binary? - Droid RAZR M Q&A, Help & Troubleshooting

While trying to troubleshoot some slowdown, I wanted to do a manual fstrim.
But by the looks of things, the stock KitKat ROM doesn't have it.
Am I mistaken? Could someone point me to getting it done?
EDIT: I already know of Lagfix, but I'd like to be able to run fstrim through adb or with shell scripts in the future, should it be needed.

How to confirm I have unrooted?

Okay unfortunately 5 mins after rooting my phone I noticed my replacement Vibrant has a bad screen. I used the one-click program to root, so I did the same thing to unroot. I downloaded ROM Manager after I unrooted to confirm the phone was unrooted and ROM Manager seems to think so (it told me to root my phone).
However, I am wondering if there is any way to *confirm* my phone has been unrooted (i.e. manually look for the root files and make sure they are not there)? I ask because I reset my phone to factory settings after unrooting, but updated.zip and chromemod folder were still present when I looked under files, which sort of scared me into thinking T-Mobile may be able to detect I had rooted.
Thanks for all the help and wish me luck for my *third* Vibrant.

Well, I know there will probably be a lot of people freaking out on me, but from how I use my phone the only use I've had so far is using cachemate to clear cache, and possibly modding the look of the os. I personally used to it to remove the annoying tmo boot and shutdown sounds/video.

Welcome to Android 30Glock
the main benefit of rooting is to be able to remove bloat-ware. Bloatware plagues the vibrant. Besides that there are other things you can do like custom roms(not many for the vibrant but they will come), with custom roms comes custom themes, also you can increase you cpu frequency. There are a few awesome apps out there that require root (Titanium Backup).
Basically think of it as you have just been given a new windows machine at work, and the admin gave you User permissions, so yeah you can do some cool stuff, but to really get in and have some fun you need admin permissions. To root/unroot this phone it is jaw dropping easy! Thank you samsung. Thank you DEVS!
Install Root Explorer and try to navigate to your system folder.

Overclocking Daemon with or without RAM optimizations

This is a tweak of this thread to work with the nexus. I claim no credit what so ever. All the work was done by Smokin1337, Rmk40, Juwe11, Sybregunne, and -viperboy-, I just tweaked it a bit to work with the nexus.
I am using this at the moment with the latest MIUI.us rom (1.8.26) and it is working for me. I am unsure about other roms but I imagine that it will work with CM because it supports init.d.
Install this from recovery and make sure to make a backup before because I guarantee nothing. Make sure to remove any overclocking apps otherwise the daemon wont work. A lowmemorykiller app such as autokiller will change the values set by the RAM script therefore you might want to remove that too.
More info on the overclock daemon here. http://forum.xda-developers.com/showpost.php?p=14529333&postcount=5

edit:
updated zips because i messed up the update-script on the original ones.
flashed zip and installed apk but cant get the gui to work the apply button doesnt allow it to apply, 1.8.26 miui
which gui version are you using? I used 2.11 and it works for me.
2.11 hangs on the loading screen for me...i get further with 1.21 but not by much
probably hanging because the install didnt work. Using adb shell, terminal emulator, or root explorer verify that the virtuous_oc folder got installed to /system/etc and has the 6 adjustable files inside of it. I will do a clean wipe on my phone and give it a try again with the files from the OP.
OK so I messed up on the update-script, I am still new to this. The OP will have the updated zips.
to tell if its working go to adb shell or a terminal emulator and type
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
it should change when you wake and sleep the phone
edit:
lol just thought about this. Will be kinda hard to check to see if it is working from a terminal emulator.
Working now thanks

How to root stock 3.2

Ok, after messing around with 3.2 I decided to fix the rooting issues without downgrading. The problem with downgrading is it requires a SDCard and requires you to install a couple of programs and then to install an update.zip from the sdcard. I could not get half my ACER's to read and mount a sdcard, and some ACER's I have located in a remote office and trying to walk someone through the process was too painful. I tweaked the the downgrade tool's images to install 3.2 with root instead of downgrading it and jumping through hoops. All I did to the stock image is to copy the ash shell over to /system/xbin/su and set the sticky bit. Everything else is stock.
Update posted here, read thead http://forum.xda-developers.com/showpost.php?p=20654298&postcount=129
New version V4
-- The instructions are in a PDF document inside the download --
== Version V4 ==
-- Added /system/subin/su which is a backup (backdoor) root in case an OTA deletes the /system/xbin/su
-- Set permissons on the su root(#) tool so OTA's shouldn't be able to break it.
-- Added drivers for XP
Summary:
Version V4 is the same as V3 with the only difference being that there is a NEW backdoor script which has some additional features to protect root(#) from getting broken when you do an OTA. I also applied these to this flash image so you wouldn't have to add the additional protection yourself. V4 also has the drivers for XP included. However, when taking an OTA you should also install the backdoor for additional protection. However, you cannot leave the backdoor installed as it turns off sound. So having a little more protection just might save your root in case you take an OTA and forget to install the backdoor.

Which 3.2 update is it ? Fully working, no issues ? Good job. Is it power + volume down or volume up to go into recovery ? And is it possible to flash a custom kernel like Honeyvillain on this stock ROM ?
Thx
Has anybody ( including OP) tried this method?
It is the 3.2 OTA for WiFi that my Tablet picked up. It is total stock other than making a SU from the ash shell and putting it into /system/xbin.
Fully works, no issues, have used it on 8 ACER 500's with no issues.
To enter recover it is the left side of the volume button which is volume (-) oopps NOT (+) as I indicated.
Hah, saying Vol +/- is not intuitive on this device since when in landscape, Vol + is the "right" side, but in portrait mode Vol + is the "top" side.

same here i run the setup file and it installs but after i run test.cmd and it cant find it
Sorry about the test.cmd not working. The script just calls adb.exe to make sure it is working and I have it installed in another directory that I did not include. I posted, to the original message an attachment, it is called fix-Test.7z that fixes the test.cmd. You should be able to just unzip it into the directory you created and run the test. The archive includes the adb.exe and dll's so the test.cmd should work. If you have adb.exe working you really don't the test.cmd, but I found out when talking someone through it (over the phone) this made sure that adb.exe was installed and they had the tablet USB Debugging turned on.
And it is a quick and easy way to get the serial number which you need to flash it.
Thanks,
Let me know if you have any more issues.
does anyone know if flashing it this way will delete all your data on the tablet?
NO GO2
The attchment does fix the test.cmd "problem" but the next step, Dotnetdetecter, does not work. It re-installs the driver (?) then error "adb is old" or something like that. All packages in my computer's ADB are up to date. I think that the "target" directory in the DONETDETECTER IS NOT CORRECT. ANY IDEAS? btw GOOD WORK!!!!!
Many thanks for this. It is really easy like this. Keep up the great work.
UPDATE
Installed, booted, but no root. Previous rom( acer update) was3.2 Gen 2, now 3.2 Gen 1. was worth a try.. Thank you... tablet is working just fine, just no root

Idk about this test thing but if u type 'adb devices' it'll show you which devices (if any) are connected. I always use that as a test when i use the adb to install apks.

Not sure what that would be. I just use the adb.exe and dlls that are in the fix.zip. Maybe you have a different version loaded?
ROOT IS NOT in the apps. It is in the adb shell.
What this does is allows you to connect to the device using adb.exe shell and you will get the $ prompt.
at the $ prompt type su and press enter. You will get # and be in su mode.
Now you can do whatever you would like. What would that be, you might ask? Well you could do the following:
1. mount system as rw
2. Push your favorite su tools to the device so they are listed in the apps (busybox etc).
Again this gets you to 3.2 with the ability to have a SU when connected via the adb shell. I left the building of the tools and custom CW to you guys to do as you wish. Here's something else you could do.
1. Shell to it, and issue the SU
2. Mount system as rw
3. Push your favorite tools to where you want (busybox etc)
4. Take the recovery.img (in the zip) and dd dump it to the recovery partition. This will put clockwork on the device (1.5).
a. You should probably run itsmagic too.
5. Get everything the way you want it.
6. Reboot to recovery and CW will load.
7. Now with CW 1.5 loaded, you can build and make copies of your ACER and make them available to anyone you like. CW 1.5 does NOT require an external SDCARD.
Sorry, if I did not make it clear that this is just a SU that you have to use from the command line. If someone wants to give me the links to a SU apk, busybox, etc they'd like included I'd do it. It would only take a few minutes as I got hundreds of these ACER's to flash for our company. I just wanted to get SU, but what the heck, I could build it out if someone would like it that way. ACER really pee'd me off with this, and guess what? They left the ability to gain root in the 3.2 100. Why the 'Sam Heck' did they change the 500 3.2 so you cannot get root?
So, anything I can do to help let me know. Also, If you never want ACER to send you another update I can tell you how to fix that too. All you have to do is the following:
1. Get to the adb shell $
2. type su to get the # prompt
3. Now mount system as rw by doing the following:
a. mount -t rfs -o remount,rw system /system
4. Now rename the update tool by doing the following:
a. mv /system/app/FDUpdater.apk /system/app/FDUpdater.apk.old
mv /system/app/FWupdateService.apk /system/app/FWupdateService.apk.old
5. To get OTA then just reverse the process if you ever want ACER and their OTA to break your fleet of ACER Tablets by pushing silly updates that they think you want then you can undo it. The last I knew, I owned these ACER Tablets and I don't take kindly to them changing something that I do NOT WANT CHANGED. They should be sued, matter of fact, I think they are violating federal laws by destroying data on MY tablets. Anyway, off my soapbox.
i have re run the new test.cmd and is working now, and have successfully run dotnetdetector but i dont want to proceed until someone can confirm if doing this will wipe all data on the tablet
appreciate it, great work btw dev!
---------- Post added at 05:05 PM ---------- Previous post was at 04:39 PM ----------
did this wipe the data on it?
Hello, may i use this procedure on my A501?
Thanks
I did NOT test on the 501 so I do not know. If it was me, I would take the 501 stock images and put them in the kitchen and root them and then replace the ones in my zip with those or better yet, use CW to flash it in.
I think the ACER 501 has cell phone data connection doesn't it? I don't think the stock for WiFi only would be a good idea.
What ACER did on the 3.2 update (my opinion) was removed the Gingerbreak exploit and they removed the adb root exploit (they left the adb root exploit in on the 100). This is what many OEM's did, however many allow you to flash your own easier than ACER seems to want to let us. So if you got 3.2 NON-ROOTED loaded then there is no way to 'hack' out a root (just yet).
So how do you root it? You have to make a custom ROM and flash it. Now ASUS/Motorola/Samsung/Toshiba all allow you to flash your own ROM if you know what you are doing.
ACER seems to hide how to put the tablet into flash mode (if someone knows please let me know). Even if you did flash it they do want those ROMS running so they take each partition and calculate the MD5Sum and write it to, I think, partition #7. Therefore, if you do figure out how to flash in a new boot image or system image the tablet will not boot because the MD5Sums will not match (if you brick your tablet this way you are fubar). Fortunately, someone wrote a tool called itsmagic which you can run to tell the tablet to rebuild these. But if you fubar brick it before you get itsmagic run, I don't know how you get into flash mode using the keys so you'd be up a creek.
So, the 411 skinny on rooting an ACER with 3.2 is to get 3.2 off the device. Fortunately, they made an earlier flashing tool to flash in 3.0. I would guess this leaked out as a way for people to reflash to stock when they have issues.
Once you are on 3.0, you now can use Gingerbreak or the adb root exploit to root it. Once rooted, you can get CW loaded. CW allows you to install your own ROM's. Without CW you can only install ROM's signed by ACER and without ROOT you cannot install CW.
So, if you flash to the 3.0 now you are 'back to the future' in 3.0, you can root and install CW so you can now install a custom ROM from your SDCard.
What I would do is go get the STOCK ROM from ACER for your 501 device.
Once you have the stock ROM, you can use the kitchen tools to unzip the ACER ROM and root it to your liking. Now, re-zip it, but you cannot sign it with an ACER certificate so it will only install using CW. No, big deal because you got 3.0 loaded with CW. You boot to recovery CW and then run the update from your SDCard that you built in your kitchen.
This isn't really that hard to do if you're willing to read some documentation.
I have no idea if it wipes it clean totally. It does walk you through the setup again (like it was new out of the box) so I would assume most things would be wiped. I would back it up and not take the chance because it is best to be backed up.
Just a note here. It says fully stock execpt root? i don't think that's entirely accurate. I believe that it's still downgrading the bootloader, otherwise you'd never be able to get CWM to run, as itsmagic doesn't work with the new bootloader. So your left with stock 3.2 ROM with adb/su abilities and pre 3.2 bootloader.
On another note, I believe step 17 is not needed. CWM run's itsmagic automatically on every boot. So just booting CWM and then rebooting to android should suffice.

[Q] Rooting the Streak 5 without USB connection

Is there a way to root the Streak 5 or install custom recovery without using USB connection? The USB charger port is broken so I am unable to connect through USB. I´ve tried to root the phone with GingerBreak and Z4Root without success. Maybe it´s possible to root the phone or flash recovery with Flash_image in Terminal Emulator but I am unable to find a guide to do so. Any help would be apreciated, I´ve searched the forums here but am unable to find the answer I´m looking for.
edit:
I´m on Android 2.2.2, 360 stock ROM, build 17397.
Well, if the answer you were looking for is "yes it can be done", then it's obvious why you haven't found the answer you were looking for.
You have to have a working port on the Streak to install CWM since installing a custom recovery requires being in the Streak's Fastboot mode. Rooting may be possible, but unlikely since you have to copy files to the \system directory, which isn't writable unless you've rooted using CWM to install the files or ADB to push them.
Short of finding an exploit to root with, he might(?) be able to by disassembling it and pushing root to /data/local and setting permissions with a pc.

ah.. i see... by taking out innerSD and manually push root into it.. it seems possible that way...
Rooting is ultimately getting SU somewhere runnable and changing it's permissions to 06755.
It just makes the most sense to place it in /system/xbin 99.95% of the time.
it seems the guy doesnt read the forum thorough enough.. because there is solution to it already..

Dont recall gingerbreak working on 350+ as dell pretty much patched everything.
I believe it works on 318 or thereabouts, but OP is on 360 he already stated it didnt work (but not which exact version of gingerbreak)
well.. at least he can try first... but it seems not possible is it?
Gingerbreak version 1.2 works on stock 351 but not on stock 360.

That sounds like a good idea since I have already cutted out for access to the internal SD card. What would be the best program for Windows 7 to push root to the SD card and change the permissions?
You would need to be able to read ext3 partitions and modify the file permissions.
I've never bothered trying under windows, the simplest way is to do it under linux.
You can install it in a VM if you wish, or you can try and figure out how to do it with additional software under windows.
Regardless you should try pushing su to /data/local/ and setting it's permissions to 06755 (rws--r-s-r-x).
If you get that far we'll continue from there
Would it be possible to get a repacked 360 stock ROM (apk or zip package) that is already rooted, and then install it on the Streak using the 360 stock recovery? Maybe that´s not possible because of the signature verification but I wonder if it would be possible. Then I would have to find someone with a rooted 360 ROM to make the package for me.

sorry to bust in. /data is mounted nosuid for a reason. Don't know whether this is so on the 360, but at least check ($ mount |grep /data) before you open your device and risk hardware damage.

Why does no root method exist for 7.1?

This is not a complaint, thought it may sound like it, but I am really curious as to why it is so difficult to root this firmware.
My understanding of how rooting works is a little outdated I guess, but from a linux hacker's POV, heres what I understand:
1) Gain read-write access to the filesystem (I understand we have this)
2) Stick a su binary in there
3) chmod 4755 it
4) Clear any issues we may have with SELinux (/ACLs?)
5) Profit!
But clearly this is not that simple. I have tried looking into the supersu zip, but so far I understand it is setting some attributes/capabilities manually?
Can someone point me to some good resources to better understand the entire rooting process?
UPDATE:
Actually, I have another question as well:
In the systemless root method, we create a loopback image, which is mounted at /su on boot. However, we still need to modify init.rc, so why do we even bother if we NEED to modify system?
