[GUIDE/HOW-TO] Beginner's "Getting Started" Guide :: Root, Recovery, Roms etc
Update: Links are dead, mediafire decided to pull them without any notice. However, all important files can be found on my DevHost Account
This guide is made to help newbies get started on the basic customizations they can do to their Galaxy Fit, and with minimum possible risk of bricking it. Plus, recent update will help users to move on from being android newbies to experienced users.
Before you think of posting as ‘copied’, I want to inform you that more than 90% of the guide has been typed by me, using my own experiences with my Galaxy Fit, and has not been simply copy-pasted from anywhere.
Note: Even though care is taken to help you minimize risk of bricking your phone,
no one, except yourself, is responsible for any damage that happens to your phone.
Also, doing most of the modifications below WILL void your warranty.

Pre-requisites:
Before you proceed, you need to have the following things ready with you:
Samsung Galaxy Fit S5670 (obviously)
Windows PC (Xp, Vista, 7)
Usb Data Cable
Samsung Usb Drivers installed on your computer (Download)
Usb Debugging Enabled (Enable it from Settings> Applications> Development> Usb Debugging)
A minimum of 50% Battery left for use
Knowledge on how to use a windows pc (optional, but recommended )
A calm mind, and plenty of patience.
Also, remember this:
a.To reboot into “recovery mode”, first shutdown your phone completely, then press and hold power + home button and wait for phone to switch on.
b.To reboot into “download mode”, first shutdown your phone completely, then press and hold power + home + volume down button and wait till phone switches on (you’ll get a yellow triangle with an android inside it, with the word “Downloading” written under it)
Edit: Since a proper "route" to installing custom roms isn't very clear, I'll just add this:-
Let's say you have a stock froyo rom, and want to try some custom rom, then
[OPTIONAL] Root Froyo, if you wish.
Then, you update to Gingerbread.
[OPTIONAL] Root GB, if you wish.
Install ClockworkMod Recovery
Then finally, install the custom rom of your choice.
Hope the "path" is now clearer ​
1. Rooting
Q) What is “rooting”? What are its advantages and disadvantages?
A) “Rooting” your device means obtaining “superuser” rights and permissions to your Android’s software. With these elevated user privileges, you gain the ability to load custom software (ROM’s), install custom themes, increase performance, increase battery life, and the ability to install software that would otherwise cost extra money (ex: Wi-Fi tethering). Rooting is essentially “hacking” your Android device.
For more info, refer Source
Though, one thing worth mentioning, YOU DO NOT NEED TO BE ROOTED IN ORDER TO INSTALL ANY CUSTOM ROM OR RECOVERY, it is optional but recommended…
People usually root beforehand as it helps them to backup their data…and you won't be able to root after you install a custom recovery, since the scripts are made only for stock Samsung recovery​
Q) Okay, now how do I root my Galaxy Fit?
A)
If you are running Froyo (android version 2.2.1), then:
Download SuperOneClick (Source Link)
Make sure your phone is connected to the computer via USB, AND your SD card is NOT mounted.
Run the app
When SuperOneClick launches, you’ll see several large buttons at the top of the screen. Make sure that the debugger can “see” it (activity will start logging).
Click “Root” in SuperOneClick.
If you are running Gingerbread (android version 2.3.x), then:
Download this update.zip file (Link)
Place it on the root of sd card (root here meaning “home directory” of your micro-sd card, i.e. the first folder which you get when you open any file explorer)
Make sure the file’s name is “update.zip” (without the “”)
Now reboot into recovery mode
Select the option: “Apply update.zip”
Wait for it to complete, and you are done!
After you have successfully rooted, you will find an app named “Superuser” in your application menu. If not, you can download it from Play Store.
Also, it is advisable to update the app (as well as the superuser binaries, option present in-app) to the latest version available.​
Q) How do I unroot my g-fit?
A) There might be various reasons why you would want to unroot your fit (the main one being to recover/reclaim your warranty)
For unrooting (in Froyo), just run SuperOneClick again, and click option “Unroot”.
For unrooting (in GB), you have a few ways: one is a sure-shot way (install/flash stock rom), another works for some and doesn’t work for some (update.zip), and one more is false un-root.
1.Sure-shot way: This method will work all the time, i.e. you will be able to unroot successfully with this method. All you’ve got to do is flash a stock rom, and you will be back to factory settings (and even get your warranty back)
2.Update.zip method: This method worked for some users, and didn’t work for some. In this, you just need to download this file, rename it to “update.zip” and install it the same way as you did to root, i.e. reboot into recovery and apply update.zip
3.False un-root: This isn’t actually unrooting, but is a little trick I used to get my warranty back.
1. First download and install Audio Manager aka Hide It Pro
2. Then use it to hide all your root-related apps (like superuser, titanium backup etc.), and done!
Note: The false un-root method isn’t actually un-rooting, as anyone with enough android knowledge will be able to tell that you still retain root access. The method only hides the notifications that you receive from superuser, when any app is requesting root access. Exercise caution when using this method, as all apps can have root access, and you wouldn’t even come to know about it.​
2. Backing up data using Titanium Backup Pro
Since you don’t need to have root access in order to install any custom recovery/rom, hence one of the major reason left to root is to backup your phone settings and data.
You can find plenty of apps on Play Store which can backup AND restore your data, but barely any other app can do it better than Titanium Backup. The free version also does quite a lot of stuff, but in this guide I’ll be explaining how to use the pro-version (v4.8.2), including how to do one-click backup as well as restore, and scheduling backups to run at a pre-defined time automatically.
First, install Titanium Backup Pro
Then, run the app.
(I recommend going through the app settings so that you can tweak it according to your preference)
Now, you can either backup apps (and their data) one-by-one or just backup all of them at once. In order to backup all of them at once, run the app, press menu button > batch > choose option “backup all apps + system data”, and then wait for the backup process to get over.
To restore backups after a data reset, run the app, press menu button > batch > choose option “restore missing app + all system data”.
Note #1: Restore all system data only if you are doing a data wipe. If you have flashed a new ROM altogether, then do not restore system data, only restore missing apps + data, else you will get force closes.
Note #2: Titanium backup automatically store its preferences/settings on your sd-card, and auto restores them after a wipe, so you do not need to bother about it again.
To set-up schedules, run the app, and then go to the “schedules” pane/tab, and then select the ones which were pre-set, or create new ones according to your need.
Titanium Backup has other uses as well (which you can find on your own), but the main important ones have been covered.
Note #3: Use some other app to backup and restore your contacts/call logs/messages...
I use GO Backup or sometimes, MyPhoneExplorer...​
3. Installing Stock Roms
First, download the stock rom of your choice from samfirmware.com
Then download beni.ops and Odin Multidownloader
Remove the sim card and memory card of your phone, and put it in download mode
Next, run Odin, and connect your phone to your windows computer. Odin should respond as detected. Then, select “Ops” as beni.ops. (Doing this would disable all other fields except “One Package”)
After this, select your desired stock rom in “One Package”.
Do not alter any other option other than those mentioned, let them remain as they are.
Make sure that the color of “COM PORT MAPPING” is yellow, and then click “Start”.
Odin will start giving different responses, and the timer in Odin would also start…now all you have to do is wait till Odin completes flashing (You will get a message “Pass”, usually within 10 minutes)
Note: Do not disconnect you phone while the process is on, and till you get that “Pass” message.
After this, it is optional but advised that you reboot into recovery mode and wipe data, otherwise you *may* face bootloops.​
4. Installing Custom Recovery
Q) I already have stock Samsung recovery. Why do I need a different recovery for?
A) The stock Samsung recovery has a very limited functionality, while other recoveries offer various other functions, and support other (better) filesystems also.
Also, to install any custom rom, you will need a custom recovery.
The most popular and commonly used recovery for Galaxy Fit is ClockworkMod Recovery v5 built by tj_style.
This recovery works with all custom roms, but it does not support backing up and restoring (Nandroid Backups) of stock roms (since samsung stock roms are of rfs filesystem).
Hence, you CAN install this recovery on stock roms, but you won’t be able to take (and restore) nandroid backups of stock roms.
However, pratyush.creed has modified this cwm5 to support backups of rfs (i.e. stock roms), you can get this from here
But for this guide, we will stick to the popular, tried and tested, cwm5 by tj_styles​
Your phone needs to be on gingerbread, as this recovery doesn’t work on Froyo.
Note: Even though rooting is not required for installing CWM, it is recommended to do so before, since you can root only from stock recovery, and CWM replaces the stock Samsung recovery.
To install this recovery:
Download the recovery file from the above link.
Also, download beni.ops and Odin Multidownloader
(Beni.ops and Odin are the same files used, so you don’t need to download them again)
Next, run Odin, and connect your phone to your windows computer. Odin should respond as detected. Then, select “Ops” as beni.ops.
Select the recovery file under “One Package”.
Do not alter any other option other than those mentioned, let them remain as they are.
Click “Start”.
Wait till odin completes flashing (might take upto 10 minutes)
Now, after your device has rebooted, restart into recovery mode to confirm that you have successfully installed ClockworkMod Recovery (CWM).

5. Installing Custom Roms
Though Samsung has possibly tried its best to create the best stock roms (compared to other manufacturers), it still has a lot of potential. Custom roms are made to achieve this potential, helping you get more returns from your Fit.​
Q) How to install custom roms?
A) Before proceeding, you will need to have any custom recovery installed, since the stock Samsung recovery cannot be used here. Preferably, use CWM5 by tj_style (the one explained above). Also, remember that your phone’s data (not the one stored on sd-card) will be erased/reset, so be sure to make a backup.
Now, download the custom rom of your choice from the Development Section of our sub-forum.
Optional: Check if the zip file you have downloaded is proper (i.e. not corrupt).
To do this, simply use WinZip (Windows) or other similar program to extract the file on your desktop. If the extraction has completed without any errors, then the file is proper, but if you get any errors while extracting, then the file is corrupt and you will have to re-download it.
Now, copy the file onto your sd-card.
Reboot into recovery mode.
Select “wipe data / reset”.
After this completes, select “wipe cache partition”.
After this, select “advanced”>”wipe dalvik cache”.
Now that you have wiped all data, select “install zip from sd” from the main recovery menu, then “choose zip from sdcard”.
[*] Optional, but recommended: Select “mounts and storage”>”format /system”.
(Important, if you are installing any variation of CyanogenMod 7 (cm7) for the first time, or are moving from a stock based custom rom to a cm based custom rom...else you will be stuck on the "android" text screen)
Now select the custom rom that you had placed on your card, and wait for it to install.
Optional: When the install completes, wipe data, cache and dalvik cache again (steps 5,6,7)
Select “reboot system now”, and be prepared to wait till the phone restarts. (Note: first boot may take upto 10 minutes, so do not panic)
Enjoy your new rom!!!
If you want to get back to your stock rom, you will have to flash the stock rom using Odin.
Also, all custom roms are pre-rooted, so you don’t have to bother with rooting again (though you might have to update superuser and its binaries)​
For your first custom ROM, I would suggest sticking to stock based custom roms...
Some sim cards aren't compatible for CM7 and CM9/10 (cm = short for CyanogenMod)...we don't know the cause and effect relationship between them, as of yet...
So, if your CM doesn't boot into the homescreen, try removing your sim card...
If it then boots up without any additional steps required, then unfortunately, you belong to the group of people who can't use CM7 with their current SIM...
The only workaround available are:
Use phone without SIM (unrealistic, since it wouldn't do the primary functions of a phone then)
Change your SIM card
Use stock based custom rom's, and forgo CM entirely
6. Creating and Deleting Sd-card Partition
Partitioning sd-card is basically virtually “dividing” your sd card into parts, so that you can use each one separately for different purposes.
So, in easy words, you can virtually increase your phone’s internal memory and ram (both of which are unsatisfactorily low in our device)
However, there is a disadvantage to partitioning, mainly a slightly slowed phone. This “slowdown” is caused mostly if you:
Have a low-speed (technical word = “class”) sd card
Have moved dalvik cache to sd partition that you have created
Have attempted to use a swap partition
But a lot of people don’t mind this slowdown a lot, since a partition allows them to have access to more apps.
Also, you will lose hot-swapability, i.e. you won’t be able to remove your card from your phone, will the phone is running.​
Before you proceed, you SHOULD backup all of your data on your card since it will be deleted, as the card will be formatted during the process.​
Q) How to create a sd partition?
A) You will need
• A good micro sd-card, with a class greater than 4
(the class is usually printed on the card itself, it’s the number inside the letter ‘C’)
• A rooted galaxy fit running android 2.3.x (preferably on a stock rom), with ClockworkMod recovery
Steps:
Backup all your data.
Reboot into CWM.
Go under “advanced”>”partition sd card”.
Select the size of your second partition (On my first try, I made a partition of 1024MB but found it too big with a lot of space unused, so I deleted the partition and made a new one of 512MB)
This is your choice, choose one depending on the total size of your card, the no. of apps/games you’ll have etc.
After selecting that, select swap size as 0MB (This one also is your choice, but I’ll explain why to take 0MB, and not anything else)
Now wait till the process is completed, and reboot.
As far as I know, CWM v5 makes a partition of EXT3 format, by default.
Q) Why to select swap size as 0MB?
A) Swap partition is made with the objective of utilizing it as VIRTUAL RAM. Now this may sound as a good thing, but in reality the ram in our fit is way faster than the average class 10 micro sd-card. So, instead of speeding up your system, it will slow down your system horribly after a certain point.
So, in short, you shouldn’t be using a swap partition, hence there is no point in creating one if you are not utilizing it.
You are still free to create a swap partition, but I shall not be providing support for that in this thread.​
Q) What if I want to delete all my partitions and get back my sd card the way it was?
A) There are a few ways to delete your partitions and reset your card, and I’ll explain the easiest one.
Backup the data on your card.
Make sure your card is in the phone’s card slot, and that your phone is booted/running.
Go into Settings>Storage, then select option “Unmount sd card”
When the card is unmounted, you will be able to select the option “Format sd card” (which you previously couldn’t)
Select the option and wait for it to complete.
If you want to delete the ext partition, I recommend doing it after a clean install of a stock rom. Else, make sure to move all your apps from the ext partition to your phone.
7. Setting up and using Link2sd
Now that you have created an ext partition, you need to make use of it (duh).
There are a lot of ways and scripts to transfer apps from your internal memory to the sd ext partition, but the most consistent method I found was Link2sd.
This method works across all roms (rooted stock and custom, both) that I’ve tried, even on all variations of CyanogenMod7 (CM7) as well as on ICS CM9 and JB CM10, and is very easy to setup and use.
However, if a custom rom already has DarkTremor's a2sd (a2sdgui app will be present) or any similar script, then DO NOT configure them.
For example: Creeds v3 has a2sdgui, and if i want to use Link2sd, then after flashing Creeds, I SHOULD NOT run a2sdgui, and directly install (and configure) Link2sd...if you run/configure a2sdgui, then it will clash with the working of Link2sd.
Similarly, if any custom rom has any memory hack already implemented, then you cannot use Link2sd...​
Steps to setup Link2sd:
Download Link2sd from Play Store (it’s a free app).
After it gets installed, run it, and allow root access.
You will get a message to select the format of your sd partition, select “ext3”.
Link2sd will then automatically create mount scripts that it requires to work, and will then tell you to reboot your phone.
Do a proper reboot, and not a ‘hot reboot’.
After rebooting, open up Link2sd, press menu then select “settings”.
Select/check the options “automatically link newly installed applications to sd”, “auto link notification”, “relink lib files at boot” (and “fast scroll”, if you want).
For “install location” option, select “internal”.
Then go to “auto link settings” and select/check all the three options (you can skip/ unselect “link dalvik-cache file” if you wish)
Done
Now, every new app that you will install will automatically be moved to your sd ext partition.​
Link2sd is also an excellent (and fast loading) app manager, with which you can freeze, uninstall, re-install…though you can move only user apps to sd-ext partition.
Also, there is no point in having your entire phone memory empty, so you probably should unlink the dex (dalvik cache) of your apps. I usually link only the apk and lib files, and leave the dex files unlinked and on the phone storage, so as to avoid any sluggishness in operation., though if your phone memory still fills up, you can link the dex of your rarely-used apps, and leave the dex of important and frequently used apps on the phone storage.​
Suppose a custom rom has s2e/app2sd pre-implemented, then after a fresh install, FREEZE the app (rather than uninstall), and then install Link2sd...
Also, if you get error "mount script not created", then choose partition as ext4 (rather than ext3 mentioned below), even though your partition might be ext3...(don't know why this happens with some roms )
If on some ROM, you get “device/resource busy”, then you need to format your SD-EXT partition from CWM (should be under “mounts and storage”)
[DO NOT confuse this with deleting and re-creating a partition]
8. Installing apk’s through root explorer method.
At times, some of your apk files won’t get installed in the normal way, so you can use this approach to install them. This method is coomonly referred to as "root explorer method".
For this, you will need:
•A rooted phone
•Root Explorer or any other file manager.
Since root explorer isn’t a free app, you can use this free File Manager (my personal preference).
If you are unable to uninstall a newer version of any app, then first uninstall the old version, and then use this method.
Steps:
Get the apk file of the app that you want to install.
Now launch Root Explorer
On the top left side, it will be written as “Mount as r/w”, click that, and allow root access. (basically mount system as read and write, if you are using other file managers)
Now place the apk file at either /data/app or /system/app (if you want it as a system file)
Now set appropriate permissions (For /data/app, the default permissions are rwx rwx rwx and for /system/app, the default permissions are rw- r-- r--)
Reboot your phone, and then check your app drawer, you will find your app installed.

12. Bootloops:
If you have flashed any custom rom/recovery/hack/kernel/update.zip, and unfortunately, have got stuck in a bootloop (i.e. you cannot reach the app launcher as the phone keeps rebooting again and again), then before asking for help, do try wiping data, cache, and dalvik cache from recovery mode...
This should stop bootloops (in lots of cases)...​
13. How to reclaim warranty?
Let's just say you need your warranty back for some reason...but have done any of the above stuff (which voids your warranty)...
Then all you got to do is flash any stock rom (preferably, of your region), and you will have your warranty back
(This, ofcourse, assumes that you had warranty, in the first place)​
14. Battery care
A lot of people have said that their battery has swollen. If this is the case, then this could be dangerous for YOUR HEALTH.
If this happens, you SHOULD replace your battery.​
Q) Why would the battery swell up?
A) My phone's battery looks safe enough, so I do not know the perfect cause. But from the users who complained about this, I did notice that most of them just leave their phones plugged in, unattended, for more than 4-5 hours at end (Usually, they just leave it to charge overnight)
So, if you do this on a regular basis, then watch out!​
Q) How do I know if its swollen?
A) To know if its swollen, just see if the battery surface is smooth or not, from all the sides. If there is any swelling, you will notice it.
Also, if you get REALLY POOR battery life, (only 3-4 on single full charge, with light usage), then this could be an indication that you have battery problems. [Just to confirm, ask other fellow users how much usage they get on that rom and baseband, since this could happen due to ROM and kernel also.]​
Q) What do I do if it's swollen?
A) There is no other option but to replace the battery with a new one. I STRONGLY ADVICE to buy them from your local Samsung Service Center. Avoid online sellers, or other 3rd party batteries, as they may not be proper.​
Q) Any precautions that can be taken?
A) Yup, DO NOT LEAVE YOUR PHONE TO CHARGE FOR LONG PERIODS, ALL THE TIME.
That's what has been deduced from the people who have complained.
Take Care!!​

9. Nandroid Backups
Q) What are Nandroid Backups?
A) Nandroid Backups are like an exact copy image of your phone’s state, saved on your sd card. It stores all your apps, data, settings, sd-ext etc. of the phone (obviously, the state when you took the backup). Nandroid Backups are a very convenient way to restore your data after something has gone wrong (or want to change between roms), and their size can be anywhere starting from 150mb+.
If you want to test some stuff from the development section (like different mods/hacks/scripts), it is advisable to make a Nandroid Backup before you proceed...​
Q) How to make Nandroid Backups?
A) Perquisites to make a nandroid backup:
•ClockworkMod Recovery (any version) on your galaxy fit.
•Plenty of free space on your sd card (this depends on how many apps you have, my backups usually average around 450-500 MB)
Steps:
Do a clean reboot into ClockworkMod Recovery (i.e. shutdown properly, then reboot into recovery mode)
Go to “backup and restore”>”backup”
Wait for the process to get completed, and you are done!
The backup that you just made has been saved to your sd-card, in a folder named clockworkmod (complete location is /mnt/sdcard/clockworkmod/backup).
Restoring:
Now, suppose, while flashing any rom, you are stuck in a never-ending bootloop, and you have wiped everything (i.e. data, cache, dalvik cache), and just want to get back the way it was, then just follow these steps to restore:
Boot into CWM
Wipe data, cache, and dalvik cache (optional, but recommended).
Go to “backup and restore”>”restore”, and then select your backup.
Wait for it to complete (time taken depends on the size of your backup, which in turn depends on the number of apps that you had installed), and reboot
You will find that you are now back to last state before you did that backup, with all your apps, settings etc. the way it was left.
If you keep more than one nandroid backup, you may find it confusing to remember which one is what…
So you can rename them in the following way:
Suppose the default name of my backup of a cm7 rom is 2012-03-29.14.04.59 , then I can rename it as cm72012-03-29.14.04.59
In this way, if you ever get a md5 mismatch error while restoring, then you can simply edit it back to the way it was.
However, if you still get an md5 mismatch error, then you can use this method suggested by fellow xda member, arhant. Though if the backup wasn’t created by you (i.e. you took it from someone else), then exercise caution while doing this.​
10. Overclocking
Q) What is overclocking?
A) Overclocking refers to running your processor above the “safe” limit set by Samsung (or the manufacturer, in general). This limit is usually set so that the battery life is extended, less overheating problems occur as well as minimum possible damage is done to the processor in the long run.​
Why to overclock:
Helps make Fit more “usable”, i.e. makes launcher smooth, games a little less laggy etc.
Why not to overclock (Most of this happens only if you don’t overclock properly):
Poor battery life
Abnormal heating of the phone
Increased instability
Q) How to overclock (oc) Galaxy Fit?
A) In order to overclock Galaxy Fit, you need to have a custom kernel, as the stock kernel doesn’t support overclocking, as well as root access.
Note: Stock roms can be overclocked! They just need another kernel, the in-built kernel cannot be overclocked.
• If you want to overclock on stock (at your own risk), you can flash any kernel from this via cwm (so, obviously you need cwm, stock recovery won’t do).
• Most custom roms have oc kernel in-built, so you usually don’t need to flash anything extra.
After you have a custom overclock-able kernel, you just need to install either No-frills CPU Control or SetCPU for Root Users (No-frills is free ) or any other such app, run them, and select the desired max frequency, governor, and i/o scheduler. (Don’t set the max frequency above 800+ mhz, unless you know what you are doing)
You have to use trial-and-error to find out the combination of governor, i/o scheduler, and max frequency, which suits your need…and you will get different results on different kernels, roms and basebands, so keep experimenting.​
11. Bricked phone
Q) What do you mean by a "bricked" phone??
A) A "bricked" phone is a phone which cannot start normally, AND cannot be rebooted into both, the recovery mode as well as the download mode...thus, effectively, it becomes just a paperweight, i.e. a brick
It is more of a "state" your phone can go into, if you do things wrong...​
If your phone can enter recovery mode OR download mode, then it is not bricked!
You can try and fix it yourself!​
If your phone can enter recovery mode, (and assuming you have a custom recovery installed), then you simply have to flash any custom rom to get your phone back in working condition.
If your phone can enter download mode, then you can install any stock rom (via odin), to get back your phone in working condition.
Note: These solutions are general in nature, i.e. they will work for the majority of cases, but may not work for some.​
HOWEVER, IF YOUR PHONE IS BRICKED,
Then there is nothing much that we can do...only the samsng service center will be able to repair it (they replace the motherboard).​

15. Android Debugging Bridge (ADB)
To put it simply, adb is two different applications - one running on your computer (Windows, Linux or Mac) and one running on your phone (which you don’t have to bother about). When your phone is connected, and USB debugging is enabled, you can issue commands and communicate with the phone using your computer screen and keyboard.
Your Android phone uses a modified Linux kernel and tools as a base. This means that quite a few Linux commands can be sent via the adb server (the one running on your computer) to the adb client (the one running on your phone) and they will be executed. – Android Central​Q) How do I setup ADB on my Windows PC?
A) With the help of my friend wilfredcool007, I have made a really simple method to use adb and also provided some tools for hassle-free logcats. This method is portable in nature (you do not have to install any untrusted application), does not need large downloads, neither the full Android SDK installation. You will just have to download a small compressed file, which is all that you require.
Thank You Wilfred!
Make sure you have the device drivers installed beforehand. If you have been following this guide since the beginning, you will have it on your computer. If not, just simply refer the beginning of this thread.
Steps:
Download this file: ADB & Logcat Tools.zip
Extract the .zip file to any suitable location, wherever you wish. I extracted it on to C:\Android Debugging Bridge just so that it’s easy to remember where it is.
Now, once you’ve extracted the zip, you will find 7 files in it [of which the 3 files named as “Logcat xxxxxx”, and “dmesg”, will be used in the later part of this guide for making logcats].
To launch ADB, just hold the “Shift” key and right click on a blank area in the folder, and in the drop down menu which follows, select the option “Open Command Window Here”.
And you’re done! Now you can use any of the adb commands that you wish! It really is this simple!
Some common ADB commands are:
Code:
adb devices – list all connected devices
adb push <local> <remote> – copy file/dir to device
adb pull <remote> [<local>] – copy file/dir from device

16. Logcats
A lot of time, you'll see developers asking for logcat. Viewing a logcat is usually the best, and in some cases, the only way to diagnose a problem.
You can do it two ways:
Within the device, through apps like aLogcat or Catlog or any other application that is capable of logging (This is self explanatory, all you got to do is download and run the app, and the app will do the work. Do check out the options to tweak out the settings and other stuff. I shall not be providing help for these in this thread.)
With ADB (explained further)
Thanks to the zip provided in the previous step, it’s really easy to do so via adb.
Steps:
If you haven’t downloaded it already, do download the ADB & Logcat Tools.zip (it’s the same file mentioned above) and extract it to a suitable location.
You have two options now.
You can either run adb as explained above and use the command
Code:
adb logcat >logcat.txt
There will be no further activity on the screen, but the logging will start. Recreate the problem that you wanted, and when you need to stop the logcat, just press “Ctrl” + “C” [Hold Ctrl and press C], and then press “Y” and “Enter” key to stop logging.
You will notice that a file named logcat.txt has appeared, and when you open the file in Notepad, you shall see its contents.
Example:
Code:
--------- beginning of /dev/log/system
I/ActivityManager( 1019): Starting: Intent { flg=0x14000000 cmp=com.whatsapp/.Conversation (has extras) } from pid 18867

Logcats get longer the longer they run. So it is advisable that you run the logcat and immediately proceed to recreate the problem.
Also, paste the resulting logcat on sites like Pastebin and share the link to the dev!​
Now, you must be wondering what the rest of the files in the Zip were for…
Well, those files are pre-configured commands for logcats to run. All that has to be done is double click the .bat files, and logging shall start. To stop logging, as stated above, press CTRL+C, then Y and ENTER.
Remember: Do delete/rename/move the output logcat file before creating a new logcat with the following files.
Files:
Logcat 1 (Long and Detailed).bat : Normal Logcat command. Same result as the example given above.
Logcat 2 (Short and Errors only).bat : Shorter Logcat command. Omits out Verbose, Debug and Info. Displays/Filters only Warning, Error And Fatal. Useful when logcat duration is very long, as this displays only the error and fault messages. Example:
Code:
--------- beginning of /dev/log/system

I know
The most popular and commonly used recovery for Galaxy Fit is ClockworkMod Recovery v5 built by tj_style.
This recovery works with all custom roms, but it does not support backing up and restoring (Nandroid Backups) of stock roms (since samsung stock roms are of rfs filesystem).
Hence, you CAN install this recovery on stock roms, but you wont be able to take (and restore) nandroid backups of stock roms.
However, pratyush.creed has modified this cwm5 to support backups of rfs (i.e. stock roms), you can get this from here
But for this guide, we will stick to the popular, tried and tested, cwm5 by tj_styles

thx to FireDiamond
Apply the "Invalid Partition Error" fix before rooting!!!
To avoid unfixable bootloop, first apply this patch from Acer.
Install the APK, start it, click on FixG1PMT (no feedback) and uninstall afterwards. Good luck!
If you're rooting with prerooted system.img.gz here are the Downloads. Pick the one, fitting to the firmware installed on your tablet, otherwise you will get into bootloop!

FAQ
Q: I'm stuck inside a bootloop after rooting!!!11
A1: The system.img.gz you applied, wasn't suiting to the firmware version installed on your tablet. Download latest Acer firmware update ( !!! if available !!!), copy it on a micro sd card, plug it into your Iconia, go to recovery by holding Volume up and Power button while device is turned off. Then choose apply update from sd card.
A2: If you cannot apply any Acer firmware, because you always get a partition error while installing, you should do a reboot after you get the error. A user reported that this made her/his device boot into Android again, showing the new version in settings -> info. Good luck
A3: If your device is really bricked you could try bring it back to life. Here you find help: link1, link2, link3, link4 (many thanks to Gilly10, drmad and Hamza91)
A4 (B1-A71, B1-710, B1-711 only): Unbrick
A5: If the A1 - A4 didn't help. Send back the device to Acer. Tell them you tried to apply an update from sd card and ended up in this bootloop. Sending device back to Acer over UPS is free. Good luck!
Q: Successfully rooted, but still no root after rebooting!
A: Have you installed Superuser App from Google Play Store?
(B1-A71 only)Q: Cannot update, always getting ERROR: - Invalid partition setting; 17: fat 238e8000:888e8000; Instalation aborted.
A: Download "Invalid Partition Error" Patch.
(B1-A71 only)Q: I applied update from RV05RC05 to RV05RC06 but still it shows RV05RC05.
A: There is no RV05RC06. It is the RV05RC05. It got on Acers Download section with a RV05RC06 named zip file. But the content is 100% equal to RV05RC05.
Q: Toolkit fails or crashes for any reason and I don't know what to do.
A: Run it again with parameter -d, e.g.: toolkit.exe -d and post the entire output here.
Q: Root from scratch on Linux doesn't work because of Error message: 'No such file or directory bin/posix/64/adb'
A: sudo apt-get install ia32-libs libstdc++6 libgcc1 zlib1g libncurses5 libsdl1.2debian
Q: Can i flash a custom recovery?
A: No, because bootloader is locked. You would brick your tablet.
Q: Are there Custom ROMs?
A: No, see answer above.
Q: Is my data wiped during root?
A: No.
Q: Do i lose root after factory reset or wipe date?
A: No.
Q: I get an error in Engineer mode entering telnet command.
A: If Swiftkey is installed / enabled try settings Google AOSP Keyboard as default.
Q: How can I start telnet server manually?
A: Try this.
What you can do with root:
Apply Supercharger V6 by zeppelinrox and significally speed up your tablet! [My small How-To]
Install Adaway, an ad-blocker for webbrowsers and apps containing ads.
Install ROM Toolbox and customize boot screen and other funny things.
Install Titanium Backup to Backup, Freeze, Uninstall any App and more.
Install Datasync to sync app data like save states between rooted devices.
What you can NOT do with root on these devices:
Change DPI
Flash Custom Recoveries
Flash Custom ROMs

Regards,

I uploaded a new version where I added some commands that hopefully resolve the permissions issues.
The problem is, that I can't reproduce it.
Are you rooting the Iconia the first time? or did you already have root before?
Regarding the progress bar. It only appears when writing the system.img.gz
I have Windows 7 64 bit, btw.

I will try to fix it asap. The problem is, that I cannot reproduce it.
I assume that the chmod 777 /cache command that I do, before the adb push command fails with "Operation not permitted."
But this I still don't know how to fix. If someone knows, tell me!

error in v.0.2.3
Dear entonjackson,
thanks for your work and for the time you spend on it.
Unfortunately, I too have problems with the tool for Windows since version 0.2.0 and also with the latest version (0.2.3).
The error messages that I receive are identical (with the same line numbers) to those receiving cakadut in his last post.
I am trying to root Iconia for the first time.
I tried with Windows 7-32bit and Windows 7 64-bit.
My configuration:
Iconia B1-A71 8GB ROM, 512Mb ram
Android 4.1.2
kernel 3.4.0
Image version: Acer_AV051_B1-A71_RV04RC04_WW_GEN1
Build Number: Acer_AV051_B1-A71_1.174.00_WW_GE
I hope you can find the solution.
Thank you for sharing your work with us.

Just uploaded a new version. Could you please try again?
It's hard to fix for me, because I don't have the problem, so all I can do is try. Thanks for the patience!

****, I think i found the bug. Don't try 0.2.4 it won't work also.

Ok, people. With pawitp's help I hopefully fixed the permissions bug.
The problem was, that i was trying to chmod the /cache directory directly from adb shell, which isn't possible. I forgot, that this needs to be done from telnet. So in 0.2.6 I'm setting permission with telnet. This should fix it!
Please report!
Good luck :fingers-crossed:

I will try to do a video tutorial, but it's very easy to do.
Download and install Ex Dialer & Contacts.
Launch the app.
Dial *#*#ENGMODE#*#*.
Swipe from right to left (to Connectivity). Then choose CDS Information and Network Utility.
There you paste this command: /data/local/tmp/busybox telnetd -l /system/bin/sh -p 1234

stell no thing happen maybe i must upgrade to pro version ???

Thanks entonjackson,
unfortunately with version 0.2.6 I can not get the ADB connection with the tablet. The message it gives me is:
"Trying to Establish ADB Connection (If this hangs, ADB Connection failed. CMD Shell Close and open a new one) ..."
and remains so without making the connection.
If I run the command 'adb devices' in another command line session, the device is seen correctly (0123456789ABCDEF device),
but when I run the new version (0.2.6) of the tool, the message is what I wrote above.
Thank you for your patience.

Unable to flash CWM

Hello! I've been trying to flash CWM on my LG Optimus 3D, but, unfortunately, I was unable to. I am currently on a stock ROM (or should I say..stuck ROM)
My device is rooted, USB Debugging is enabled, I tried with ROM Manager and Recovery Flash (both from the Market) as well as two PC application. Here is what I get from the CWM Recovert touch installer:

Thank you very much, my friend! I shall try to do this. However, I wanted to find a ROM that is below 4.0.4, I already have the stock 4.0.4 installed, and it is really, really slow. I was looking for an older ROM but unfortunately all links are dead..And CyanogenMod seems not to work for me --'

If you do a search on the optimus 3d forum for "downgrade to gingerbread" you will find help to downgrade. A gingerbread (2.3.5) rom can not be used if you do not downgrade from ICS. None of the rom manager type of apps that are available from the play store work with this phone.Only use the methods to install roms using the recommended methods in the optimus 3D forums
If you upgraded to ICS using LG official update tools, many users have had problems after upgrading. Try the method described in my original post and if you are not happy with the results maybe then try a downgrade.

Bugs/strange things:
in call the proximity sensor don't turn off the screen it happens only if you have enabled the loudspeaker or use hearphones
for 3rd part apps use this to enable the airplane mode (with llama is not needed)
sound volume:in sound options play a little with the notify/ringtone level, check or uncheck the separate volume option and play again with notify& ringtone level, to me they change together also with the "separate" options solved in 18/08/14 rom
could i update to the latest normal or ota nightly? NO, you need an OS2SD rom, see the summary to make your os2sd rom
wifi battery drain
wifi hotspot,it need a reboot after use
fm not working
If you use Instagram, download the v.6.3.1: http://instagram.en.uptodown.com/android/download/72905
please refer to this post for instagram downloader and xposed module etc (thanks to xu3sno)

How To:
- Repartition SD card, the minitool partition tutorial:
Now in the first post of the HardLight's thread, under "Installation instructions" there are two beautifull "Partitioning guides", please follow one of them step by step
start minitool partition, chose minitool partition wizard,
select your usb disk (i.e. with my 8gb sd i've selected the disk "basic 7,47 GB" )
if you have also a sd with 2 or more partitions you have to delete all partitions -> select partition and click on "delete" button
when you have all the space in your sd "unallocated" (in gray) you can create the partitions needed
so select your unallocated volume and clic the "create" button
if minitool say "the new created partition cannot be used in win..." click yes
in partition label: leave blanc, don't give it a name (no /system, system or anything else)
in create as select "Primary"
in file system select "fat32"
in cluster size leave default
in size location unallocated space before 0.00 MB
partition size 5900 MB
click ok
do last steps for a second partition: primary, select the file system "ext4", partition space 450MB (You need 380+ mb for system on f2fs.)
the same for 3rd: primary, select the file sistem "linux swap, partition space 128MB"
the same for the 4th: primary; select the file system "ext4", partition space ~1.100 MB
in the end you have to CLICK THE APPLY BUTTON, else nothing happens
partition scheme for F2FS only:
1st: 5850 mb FAT32
2nd: 450 mb EXT4 (before flash the rom you have to change the file system to f2fs in TWRP-> select wipe->advanced wipe->SELECT Data -> click Repair or Change File System->Change File System>F2FS->swipe to change)
3rd: 128 mb linux swap
4th: ~1.100 mb EXT4 (change the file system to f2fs before install the rom)
- Overclock & Performance settings
To enable the performance menu you have to:
go to settings->about phone-> and tap tap tap tap tap tap ... tap on the "build number"
Now you've "dev options" & a "performance" menus at the end of the "settings" menu.
In dev options:
you can find 3 scale animation options, set them to 0,0x
In Performance:
set CPU min freq to 320, max to 729 (check "the set on boot" option) ... warning someone can keep 800+mhz but at long time this can BREAK (really) your phone & use a lot of battery
set Governor to smartassv2
set in I/O scheduler -> SIO or DEADLINE (check the "set on boot" option)
set in Memory -> check the Kernel page merging
uncheck "force high end graphic" (if you don't need a transparent notification bar)
make a reboot after these settings is highly recomended
in Testing PurePerformance mod
- Superuser update and titanium backup problem
if you have Superuser problem with titanium backup: i remember there was a fix to that, but the simple method is to install supersu (via TWRP) from the playstore
- Navigation bar with soft key
edit the build.prop and insert
Code:
qemu.hw.mainkeys=0
to show navigation bar with soft key
update, thanks to xu3sno
Well, for transparent/translucent status bar and softkeys, just edit build.prop, find ro.config.low_ram= true, change the value to false. It will enable translucent status bar.
Still in build.prop add line qemu.hw.mainkeys=0 in order to enable softkeys in navigation bar. Save > exit > reboot system.
Softkeys with L theme, install this module (you need Xposed of course). To enable L theme softkeys, go to Settings > Buttons > Buttons and layout > tap reset. However, once the screen lock and open, softkeys will back to the traditional one. Don't know, may be it's a bug.

- Mod power button<-> search button (if your power button is broken)
the search<->power button mod can be applied in the rom zip before to flash, with 7zip open the CM-11-XXXXXXX-NIGHTLY-OS2SD-p500.zip\system\usr\keylayout and you need only to sobstitute the 4 files manually inside the zip ( see in the mod thread -> manual version)
- Saving Battery
refer to this thread
and to this explanation
please don't use tweaks like the parsley
i'll test the wifi.supplicant_scan_interval=180 in the end this build.prop change don't saving power if wifi is connected but when not in range of a known network and you leave wifi on, you can set from 120 to ...3600 (i think is the time expressed in seconds to wake up the wifi and to check if there are known network).
2nd test: the bigsupersquid's patch need a new kernel, not applicable ATM
bigsupersquid patch and dovidhalevi iwconfig suggestion
on the second p500 (yes!, i use it only in aereo and wifi because i've no 2nd sim)
- Dialer pad number problem with L theme
If you see this in your dialer:
there is a problem in the L dark theme, until the theme dev will solve the problem you can click where you usually write phone numbers and swipe to the top.
or in the "speedcall""all contacts""favourite" tabs click on the search bar on top and write a number to call,now you can call the number directly from the search bar or then if you click the pad icon can see the full pad number
- Make any rom an OS2SD rom
Please read the HardLight Guide
try this if you want the latest nightly
Images:
with kitkat original theme and with L theme (Android L - CM 11 Theme, thanks to tung91 )

i see in the updater-script that the mount point is set to this
mount("ext4", "EMMC", "/dev/block/mmcblk0p2", "/system")
a simple question, if i use this updater script mod with other rom (i.e. rhar****'s omega) and your TWRP could i make my "omega os2sd" or there is something else to change?
ah i pushed the thanks button, but however i want to say Thank you for your work
edit:
added at 1st post the link to the HardLight's os2sd guide

Anyone tried using this rom with a class 4 sd card? I think I'm about to try it, even though I'm pretty sure it'll be slow like hell

a little bit, maybe,however also the internal memory transfer rate is 5-10 mb/s (lower than an usb2 transfer rate), is not like the hdd internal transfer rate (hundreds mb/s) or an ssd (gb/s)
what i can see is that, few apps = the phone is quite fast
much apps need internet connection = the phone is unusable
i've a decent use with Whatsapp on, but is the only app with data necessity unfreezed
the amazon store,appfree, skype, teamviewer etc. are freezed, and i'll unfreeze when needed

For some reason I never thought of freezing data apps, might give it a try.

So I took the bait and installed it. Apart from the obvious delay when opening most apps (which is perfectly bearable so far), the rom runs smooth as silk. However, I don't have any additional apps apart from google's yet, so I still have to try that out. Time will tell.
PS: battery usage seems to be way lower so far (except for the wifi drain) when compared to gingersnap (which I was using before), and that's a first to me. You can barely say this battery is 4 years old (it's actually quite obvious but whatever x) )

Bricked?
I've flashed this ROM with files for broken power button mod and gapps. After first boot everything seemed to be working but I was getting constant keyboard crashes so I've tried all that "reflash gapps, clear cache etc." As it didn't solve the problem I've downloaded a keyboard on PC but I couldn't connect the phone via USB (there was no notification about connection and nothing showing up on PC). Then I turned off the phone and I can't turn it back on and I can't enter recovery. It's completly dead. The only thing that is working is offline charging. However when screen turns off after a few seconds I can't wake it up with any button. What to do?

Please at this moment don't use the f2fs version, it's only for the brave, in the OP there are 2 kind of rom: a f2fs version and another not-f2sf
keyboard app problem -> go to setting -> app -> select keyboard -> clear data, clear cache (into this menu, not in the recovery or something else)
else you can try with another keyboard, usually i set swiftkey as default.
See you the LG logo and after a black screen?
if you didn't use KDZ or LGMDP to flash roms, usually you can enter in recovery (if somethings go wrong with LGMDP or KDZ you make an hardbrick).
so don't use KDZ by now
how to enter the recovery: pull out the battery, wait 2 sec, reinsert, push power on button (you can see the LG logo) and after keep only vol down and home buttons.
if you can see the recovery then reflash the rom
sometimes after the LG logo you see a black screen, please check if the phone is off or the screen is on but black, if it's black it could be you didn't pressed the vol+home buttons in time
if you have problem contact shinobisoft or HardLight and search the howto unbrick/revive p500 guides in xda (i remember that there were 3 or 4)

with latest file system mod (f2fs) it should a bit faster, tomorrow i'll test on my 2nd p500 (actually with omega rom), see the HardLight's thread

I've managed to somehow turn on the phone but i still have 2 problems:
Crashing keyboard app. It has no data and 24.00KB cache. However I don't know if I can clear it because when I tap on "Clear cache" nothing happens and it stays at 24KB.
I can't add Google account. In settings I tap on "Add account" and nothing happens.
Factory reset and reflashing gapps didn't resolve those issues.

about this problem,
i have tried f2fs builds from 8/30, 9/5 and 9/8 ... and i cant get gapps to work in any of those ...
however gapps are working fine on ext4 version ... tried two latest from hardlights drive
is it possible that gapps are just not working on fresh install f2fs builds?
and upgrading from ext4 version to f2fs with converting data partition should work ?
/edit
well nevermind, hardlight uploaded new version of gapps and f2fs build works for me now
thank you hardlight & everyone affiliated

reported to HardLight's thread

[ROM & discussion][7.1.2_r11][Grouper|Tilapia][3May2017]AOSP - UNOFFICIAL

In Android ROMs' developments, I always start with AOSP. It is the root and if I want to do it right, I have to make it work for AOSP first. Putting the AOSP tests in my kernel thread is getting messy. As I would continue my work here for a while. Starting a thread for AOSP seems reasonable.
Here is for sharing of experiences and discussions.
There would be no nightly, weekly or monthy. I would follow the releases of AOSP and keep it as genuine as possible. If you are looking for a feature, there are many nice ROMs out there.
Known Issues:
　1. AOSP Camera App　The AOSP Camera2 app is not working with the Nexus 7 (2012) which is the only (I think) Nexus device with a Front Camera but not the Back Camera. The new Camera2 app set the back camera as default. I can make the preview shown by a simple overlay configs. But, make it really work would be quite a work. In the app market(s), there are many camera apps already taking care of that and would work flawlessly. I see no reason to waste time on that.​　2. "E:unknown command [log]"　If you got this message when flashing, don't panic. It's the new "block_image_update()" in recovery cause that. It would do no harm and it would be gone in the next TWRP.​　3 Please report.
Tips:
　1. DT2W　At deep sleep, the idled CPU takes time to resume. If the taps are too close, it might not be recognized. Delay the duration between taps would give you better results.​　2. Built-in File Explorer　There is an built-in file explorer in AOSP. We can explore the files as well as installing apks.
Its in: Settings > Storage > Explore (under the storage you want. In case of Nexus 7, only the internal and OTG exist.)​Change log:

DT2W
Sometimes it won't wakeup after a long DEEP_SLEEP
When volume buttons are also enabled for wakeup. It won't work too. Seems there are situations "soft pwr button press" won't work.
Fail after reboot
Code:
Supported API: 3
E: unknown fs_type "f2fs" for /cache
E: Can't mount /cache/recovery/last_locale
Some of you might encounter the above message after reboot. I never encountered before but there is definitely something wrong.
@millosr found that it was the recovery being replaced. I think that make sense and I want to study why.
I looked into the source. In the original AOSP, an OTA might come with a recovery patch. Stated in the build/core/Makefile "boot.img + recovery-from-boot.p + recovery-resource.dat = recovery.img"
It would generate the "recovery.img by the above formula itself. Custom ROMs usually won't carry a recovery and this part was usual ignored.
There is a warning in TWRP before reboot. Some of you might not read clearly and slide to continue immediately. In that case, the above mentioned recovery.img will be generated and flashed to the /recovery partition. Everything seems normal but after reboot.
When the script kick in, it would execute the "new" recovery. As a normal recovery, it would load the fstab and try to mount the partitions. The current fstab version is API 3. Almost all ROMs (no matter how close to AOSP) would have F2FS support. When we open a typical fstab:
Code:
/dev/block/platform/sdhci-tegra.3/by-name/APP /system ext4 ro wait
/dev/block/platform/sdhci-tegra.3/by-name/CAC /cache f2fs noatime,nosuid,nodev,nodiratime,discard,inline_xattr,inline_data,inline_dentry wait,check
/dev/block/platform/sdhci-tegra.3/by-name/CAC /cache ext4 noatime,nosuid,nodev,nomblk_io_submit,journal_async_commit,errors=panic wait,check
Note that the second line is the declaration for the /cache in f2fs. Stock AOSP recovery doesn't support f2fs. That's why the above error shown. Since it fail to mount /cache, the last_locale is not loaded and recovery would hang.
How to recover?
Naturally, you have to flash TWRP again.
First of all, you need to boot into bootloader (fastboot mode)
Some init.xxx.rc might start adbd earlier and in this case "adb reboot bootloader" would do the job.
If adbd was not started before the hang, the command won't work. In this case you can only use the pwr+vol. down combination.
If it is still hanging, the buttons might not work. Press the power button continuously might lead to repeatedly reboot. It is better to make sure the device is OFF first.
1. Connect to a charger.
2. Press the power button until you see the charging image
3. Release the power button immediately.
4. After that, press the volume down button first, and then the power button.
It would go to the bootloader.
Note: /system is not really formatted during flashing. To make sure no residue left in /system, it is better to wipe the /system before flashing.
For ROM builders, there is a flag BOARD_USES_FULL_RECOVERY_IMAGE. Set it to true will stop the generation of recovery-resource.dat (in /system/etc) and break the above formula.

Does D2TW require the digitizer to remain permanently on? Trying to guage the impact of such a feature before I turn it on.

Thanks for bringing nougat to our beloved Nexus 7!!!
I just flashed but no matter which gapps I use, I can't make playstore and google play services installed.
Any hints?
Thanks.

If you want anyone to help, you have to provide details.
The tested Gapps' are listed in OP. "No matter which gapps" ?
Can you tell us which one and version you actually tried?
What's your flashing procedures? etc.

Procedures (clean flash)
- rom
- gapps
- supersu
- reboot
- no playstore/play services have been installed after reboot
I used explorer to check and found that those gapps are installed (e.g. Vending.apk) but their sizes are all in 0kb.
the gapps I used were opengapps PICO and Banks. (I tried both. All after clean flash)
Finally I got playstore installed as follows
- flash rom/gapps/supersu
- reboot
- uninstall some system apps I don't need
- flash gapps again
then the playstore appears in app drawer. (And it works)
However, I have another big problem after reboot.
My device is now stuck in bootloop after splashscreen.
It just shows message as follows and I can't enter recovery/bootloader.
Supported API: 3
E: unknown fs_type "f2fs" for /cache
E: Can't mount /cache/recovery/last_locale
In the following page I found a solution "adb reboot bootloader" but I can't even enter bootloader/fastboot mode.
http://forum.xda-developers.com/nex...ip-linux-tegra-nv-3-4-bringup-t3128195/page46
still trying...
Any helps would be appreciated.
Thanks.

I think you are not using the Official TWRP. There are similar reports having the same problem for other MM ROMs too.
You may try the Official TWRP 3.0.2 here (follow the link if you have a Tilapia) and flash everything again.
You might have corrupted your /cache and /data. It is better format them (to ext4 or f2fs) in the Official TWRP again.
Good luck!

Thanks for your suggestion but the TWRP I used were downloaded from TWRP's official website, so I supposed it is official version.
I can't flash TWRP again as I am still struggling to enter bootloader mode.

Which version? eariler version might have a wrong fstab which have issue on f2fs.
Make sure you got the latest version 3.0.2
You can't go to boot loader?
That means you press pwr+vol down and it won't reboot to bootloader?
That's strange.
"adb reboot bootloader" only work if the adbd is up. That means you can use "adb devices" to check the existance of your device.
You may try this:
1. connect to the charger
2. pressing the pwr button for > 8 seconds.
See if the tablet reboot. If yes, it would boot into charging mode. Pwr+vol down again would work.
If it doesn't reboot after you pressed say 20 seconds, you need to remove the battery.
Good luck!

Thanks for the new AOSP build Daniel. Nice work fixing the hardware decoder, my Netflix is now working and I was able to play one of my MP4 movies with BS Player in HW mode. I've been changing back and forth between your first AOSP 7 build and your DU 7 build with dirty flashes. With this build I decided to clean flash and at first things were very sluggish but settled down after a reboot and probably after Google finished whatever it does in the background. LOL Aside from a few occasional random force closes, it's running pretty well.
A couple of observations:
As mentioned, I did a clean install with this build. I'm using official TWRP 3.02 and installed the rom and 7.0 Open Gapps nano 20160915 at the same time and when it booted up for the first time, there were no gapps installed. I powered down and then went back into TWRP and reflashed the gapps, this time they were there upon reboot. Surprisingly, I didn't have to set permissions for Google Play or Play Store, as they were already correctly set??? I did run into a snag when trying to download apps from PS, clearing the data for the download manager app solved that problem for me.
I installed a camera app (HD Camera) from Play Store and it works but when I use my phone's camera, it reminds me how crappy the N7 camera is. LOL
After setting things up, I wanted to try phhsuperuser (no Magisk) to root and it went fine. All of my apps that require root worked...except Titanium Backup. I tried uninstalling/reinstalling both phhsuperuser and Titanium but couldn't get it to work. I rely on Titanium quite a bit, so I flashed Supersu 2.78 and all's well.
Thanks again.

Do games work on this rom?

Hi,
This is the best 7.0 ROM so far !!!
Smooth, video HW decoding is working, games work perfect.
As webdroidmt said I also had to reflash GAPPS to have GAPPS installed and i had to give proper permissions on Google Play service to stop seeing the "google play service stop" message.
All Apps/games that i installed are working properly.
Thanks Daniel_hk for your work

Many thanks Works like a charm !
Is SEpolicy restrictive in your build? (I cannot see it from Settings -> about tablet)
.
Can you post your manifest on Your Github for easier building ?

Hi, currently testing your ROM, looks awesome!
When Browsing the web with Chrome, loads and loads of SELinux denials, mostly when the page loads:

In any case, it's a good practice to read the console after flash anything. There might already be essential messages which not necessarily in red.
I also experience SuperSU need to flash again. I just found out something that might help. Seems SuperSU would use the cache to start a checking process in the next boot. I don't know if it would help gapps too.
1. Try factory reset before flashing.
2. Flash ROM+Gapps+SuperSU
3. After that don't do wipe cache/d-cahce again. (factory reset already include this action)
Good luck!

I think you meant "Enforcing". Yes, it is enforcing. Only some Custom ROM would show this in About but not AOSP.
There is a shell command "getenforce" which you can check the SEPolicy status.
If you read the OP, you would know its an AOSP without any mod/tweak, just porting. You can get the manifest and all the helps in https://source.android.com.
Good luck!

Chrome has many versions and it should not be an untrusted app. I'm testing the CarbonROM which has a bloated Chrome and being treated as isolated app. It might take time for those UID's being properly handled.
I already included some extra permissions which would be include in my later builds.
Anyway, we would encounter denials more often in apps. That's what newer Android intent to do.

This is repeated every 5 minutes during deep sleep. I'm not an expert, but this probably doesn't help with battery drain
I'm also having some touch sensitivity issues when coming out of deep sleep or off the charger. I have to do some more testing, then I will have more details.

I wanted to try this 'Sept 23' ROM as it should play video OK: in the end I got it to work, and I can now indeed play video in some video based apps that did not work before. I used the older DU ROM and also the nAOSP ROM of millosr. There video does not work yet.
But with this Sept23 ROM I had a fight with Gapps to get it to work... First the Gapps I normally use failed to install in TWRP. At least, that is what I think I saw: the progress bar suddenly jumps ahead as if the install process was broken off somehow. So I again clean wiped all and now used opengaps-pico. That installed fine, but on first boot, no gapps. So I again installed opengapps and now finally I had working playstore. Strange, I never ran into something like this before (I am mostly active on Xperia S with nAOSP).
But the story ends well, as my video now works: great job !

Did you set "keep wi-fi on during deep sleep" to NEVER?
My tablet drain 5% during this night (about 8 hours), so i guess this is normal/acceptable
