From what I can tell anyway. I was working on this, and I had it working up until installing a new app from the Market. Here's the tutorial I wrote:
Code:
Note1: This process can brick your phone, and it can crash the Android OS. Please use with caution, and know that you are responsible for your own actions, not me, nor anyone else.
Note2: If the Android OS does crash (signified by the Android loading screen, with the flashing Android logo) a factory reset is your best option. It saved me a few times when working on this process.
Note3: Note that a fresh start (factory reset phone) is best for this process, as it changes where all apps are going to be stored and used from.
Note4: Your SDcard cannot be accessed when the USB cable is plugged into your computer, so note the apps will not work/will not work well if you are connected to a PC.
Get root
In terminal:
1. su
2. cd data
3. mkdir /sdcard/data/app
4. mkdir /sdcard/data/app-private
5. mv app app2 (don't want to delete the directory terminal is running from, also kept for backup)
6. mv app-private app-private2
7. ln -s /sdcard/data/app app
8. ln -s /sdcard/data/app-private app-private
And bam! Done.
I then used adb push/pull to backup the app and app-private directories to the SDcard. (just in case, for the terminal app. And I tried this process with and without this step, so I know it isn't this messing it up)
Now Terminal Emulator runs, as well as everything else, but when I download/install a new app, my phone freezes as it goes to install it, and then crashed and goes to the Android OS loading screen forever.
I also worked on this and ran into the same problems you have...I know that there are some other folders that deal with the apps we download from android market.. One of the problems you may be having is that when installing there is an intitial setting up communication that is trying to occur between the downloaded apps, /sdcard/app, and other folders on the phone. When the sdcard/app trys to communicate back with the other party, your errors occur and you crash....I would suggest doing this again, hooking your phone up to DDMS and reproducing the crash again so that you can see what is throwing the errors...that may give you a better idea of what else needs to be done....
I would love to help in any way possible as I was working on this as well, btw, when you get stuck at the flashing android, there is no need to do a reboot, you can plug your phone into your computer and run the adb shell even though it isn't booting up. Since you can run the adb shell, you can fix the problem. Also, you could run DDMS to see what is keeping it from booting as well.
Me too!
I'm working on this as well, I will relay any progress I make, hope you will do the same.
Thanks!

one question .. why are you trying to install apps to /sdcard??
This is an old thread that got bumped. This is not the way to go about getting apps to install to the sd-card.
Hello friends, Please note that i tried installing ClockworkMod 3.1.0.1 but it refused to setup for some reason, even though i did everything right i.e. holding down the down vol key and power button etc but like others i only get the green android with the exclamation mark in the middle, so i do not have a backup unfortunately ;(
Anyway the story starts here:
Please be patient with me though as i am new to all this but learning fast.
Got a new Asus transformer TF101 (with keyboard) for only 5 days with
Device serial: B70KAS3?????
Build number: HMJ37.WW_epad-8.4.4.11-20110711
Android version: 3.1
Didnt know about Razorclaw ability to root B70 :-(
Anyway on going online on the TF101 for the first time, I immediately got a message saying there was a new os update available, the TF101 auto downloaded it and i then immediately updated it, thinking that the new update was best for me :-(
After the update, i then had -
Build number: HTK75.WW_epad-8.6.5.21-20111216
Android version: 3.2.1
Razorclaw doesnt work on my TF101 however i was able to use use the WW_epad-user-8.6.6.19.zip update on it and then was able to root using Razorclaw.
After that everything worked fine until i used 'Rom Manager' to create a script that was to change my hostname to my preferred one instead of the usual 'android_????????????', i then set it to do so on boot within 'Rom Manager'.
I then used 'Rom Manager' 'reboot' script to reboot the TF and now it boots then flashes locked screen for a second and shuts down and the same thing happens when i power it up again
If i am lucky and quick, i can put in the password and see the desktop just before it shuts down.
I have a feeling it the script i created and set to execute on boot is what is causing the shutdown.
Is there anyway to fix this?
It not a low battery issue, already checked that.
Was thinking along the lines of a key combination to prevent scripts running on boot time.
Dont really want to wipe the TF, as it already taken me 5 days to get it setup how i want it and now this!
It sounds like you have a stock recovery and a buggered up system.
You might be able to recover with adb, but you'll have to know what to stop/kill before it reboots. If it's enable, adb will be active well before you see the lock screen. There might also be some tools in the android sdk, perhaps ddms.
What exactly is in this rom manager script? Perhaps it is passing a reboot via one of the partitions. You would need to clear the command to stop the reboots or just kill the process that is rebooting.
That's all I gots. Good luck!

thanx for responding mate...appreciated.
the script is just a simple script with just one line with tr3ble being the new hostname, its exactly as below:
setprop net.hostname tr3ble
I'll have a tinker with adb but what how do i search for processes to stop/kill using adb as im not that clued up with linux commands
I'm not a pro either, but I think "ps" will show you the process and "kill <pid>" will kill them. There might be a better way and I haven't tested this, so if you end up in a worse situation than then one you are in, it's all on you.
I don't think that changing the hostname will cause a reboot. I think the "reboot" command from rom manager is somehow stuck. I think it passes a reboot command via one of the partitions so that it can "find" it when it restarts. You would just have to clear the command. I think it's somewhere in the /cache directory, but that is just a guess.

Wow...you are definitely pointing me in the some direction though, in the begining i didnt have a clue what to do and where to look but now i have a few things to try...i'll see how things go with adb and report back.
Thank you for your time and patience mate
Update:
I tried everything i could but just didnt seem to have much time to do much using adb so i bit the bullet and did a data wipe, but to my joy, after the data wipe the TF was still rooted and my adhoc hack was still in place. If only took me bout an hour to then reinstall all my apps, which was more or less easy as i had them all in one folder on my microSD.
So all in all, the data wipe which cured the shutdown after restart wasnt sooo bad afterall.
Thank for your help mate!
....Happy New year!

Hi guys,
I've been reading you for a while, but this is actually my first post.
Currently stuck with a "Unfortunately, Launcher has stopped" on my tablet, with no access to any menus except my Settings. The menu bar (back, home and multitasking) is now gone. I've got my keyboard to navigate, but something in the display is also quite wrong, image seems to be zoomed, or set at the wrong resolution. Tried to search on the forum, but all posts found were not about the same rom or the same issue. Sorry if I missed one.
Here's a little background story:
I've rooted my TF300T about a month ago and installed Hydro 4.1. It has been working very well since then, but in the last days, I thought that my tablet felt a little slower than usual, so I started searching if an update to 4.2 was available.
I'm not sure if this is what caused the issue or not, but I went into my "Power button" menu and went into "Recovery" mode (instead of Shutdown, reboot, etc.), which then restarted my unit into TWRP menu.
I then selected the "System" submenu and simply touched "Reboot". (terms might not be exact). At the first reboot, I got the problems that I described.
Can't do much, popup keeps appearing on my screen. I haven't tried yet to clear the cache of my Launcher, which I'm trying to avoid as I would prefer to avoid rearranging 5 pages of icons, but between that and reinstalling everything, obviously I prefer to simply lose my display preferences.
Can anyone help me about what caused my issue, and what can I do now?
Here are 2 screenshots that I took, showing that my bottom menu is missing and that the fonts aren't set right (clock and left icon). Also, my notifications menu now appears near the middle of my screen.
EDIT: I unfortunately cannot post links yet
I remember installing an app (with root access) that gave me a menu about my resolution. One thing that I'm wondering, could it be that the resolution got changed and I simply never rebooted since the change, which now caused my Launcher to crash? How can I launch an app without having access to the app menu?
Thanks in advance for your help.

What you describe is likely caused by changing the resolution. Are you still running hydro 4.1?
You can likely recover by replacing your build.prop or editing the one you now have. build.props are usualy rom specific so you need one from the rom you are using.

Yes, still using Hydro 4.1. I do have a build.prop editor installed on my tablet, but since I can't launch app, I don't know how to do it.
I'll try to connect the tablet to my PC and see if I can get access to my file from there.
Thanks!

I'm presently downloading 4.1 hydro to retrieve the build.prop. If you unzip it the build.prop is /system/build.prop also located there on your tab. I have another fifteen minutes to download if you wish for me to supply the file!

Only thing left, how can I send the file to my TF300T without access to my apps? I'm currently trying to cheat by opening my apps using the Share feature with screenshots taken, but so far, no success.

Open terminal or cmd in the directory with fastboot.
Boot into twrp – twrp provides adb access by default.
Use twrp mount menu and check mount system.
Then type

FYI, before I got your last post, I used Android commander to push the build.prop that I still had on my PC when I installed the custom hydro 4.1 rom.
After my reboot, I got the Asus logo, than a black screen that does nothing.
I then rebooted in Fastboot and followed your instructions.
So now, it seems that my pc doesnt see my tablet anymore when in TWRP. is this normal? Do I need to restart it after checking "Mount system"?

Slowdown, I'm getting behind. I'm willing to help but you are now worse off than before.
Sit tight for five minutes and I'll try to give you a twrp flashable zip for your build.prop and hope that is the extent of the damage.
If not we'll try to go from there.

This is a twrp flashable zip that only replaces your build.prop with the one from hydro 4.1.

Alright, I'll wait for your answer before trying anything else.
So now, I've got your latest .zip file.
Still can't see my TF300T from my PC, so, ADB is a no go for now.
In fact, I do see it in the Device Manager, but since my last reboot, it now shows an exclamation mark on it as if my drivers weren't good.
Since you mentioned the file is a flashable zip, I'm guessing that I can flash it using TWRP without going through my PC?
Can you give me precise info on that, since I do not want to mess with my system more than I already did.
Thanks

Look at the bottom of my previous post. You will find a new link there. Just flash with twrp and reboot. Don't worry about wiping or any of that, just flash and reboot.

Yep, that's the file I was talking about.
I now need to flash and reboot, your file is at the root of an SDcard in my TF300T, I go through the Install menu and then, can't seem to view the content of my sdcard. Tried to mount it first but can't select it either, it will simply stay on "Internal Storage".
EDIT: The RCK icon is the only one right now that boots me into something. If I try the USB icon, it just stays on that screen forever.
Trash the two zips you have downloaded. I'm providing a new one for when we get back to that point. And there will be no doubt about which zip you are using.
http://www.mediafire.com/?hagehu5qu5ky6sf
OK. First I'll explain your earlier comment about adb being old. Twrp expects a recent adb or refuses to allow adb access ( we'll not worry at the moment about that but it is something you need to address later (I hope).
If you have a cord between your tablet and pc remove it. The sdcard may be mounted as data on the pc and not allow twrp to mount it.
You have been using this sdcard prior to this exercise?
Do you have any backups or flashable zips or anything of that nature on your internal sdcard?
If so what?

Zips trashed, kept only the one provided in your latest answer.
No cord between PC and tablet. Still unable to click on "Using external SD" or "Mount SDCard". It simply won't let me check the box or switch the bullet.
As for using this SDcard before, yes in a PC, but no, first time in my Asus. Also tried with another one just in case and same result.
As for backups and flashable zips, I kept everything from when I did my root and rom install.
I do know that I have a backup in the Restore menu of TWRP, which seems about the time I installed it. I suppose I could simply do a restore and avoid additional headaches, but my question is, what exactly will it restore? At this point, I'm mentally prepared to go back to what I had after installing Hydro 4.1, as long as I can use the tablet ASAP.
Asap = restore your backup.
If I'm restoring a different rom I'll wipe Cache, Dalvik Cache, and Factory Reset. If the backup is from the same rom I'm flashing and I want to keep the apps I have Installed since the backup I won't Factory Reset.
Good Luck!

So, I did the restore, and I'm up and running, but, no more Hydro 4.1. I guess my backup was probably what got done right before the installed it.
The good thing is, my tablet is working again and my root is still active. The bad part is that I'm gonna have to dig my head again in all the tutorials and try to find the best one.
Hey, I wanted to say a huge thank you for all your help, if it wasn't for guys like you, newbies like me would be stuck with useless thin computers.

Great I'm glad you are happy. I had hoped for the outcome you expressed but this works also.
You're welcome!
So I've had a bit of bad luck mixed with poor timing. Here's the run down.
I have an Asus Transformer TF101 which was running the stock rom.
I rooted my Tablet a few weeks back without any problem. Things were great. Then, I tried to upgrade to Jelly Bean from ICS using Team EOS (I followed these 2 threads mainly, http://www.transformerforums.com/fo...ficial-faq-teameos-4-android-4-2-x-tf101.html & http://forum.xda-developers.com/showthread.php?t=2063406)
I put the ROM and all the files needed onto my micro SD card.
I booted into TWRP and followed the instructions. Things seemed to have gone great. When I rebooted, I saw the new splash Logo upon bootup and awaited it to do it's thing. It never did. I let it run for an hour and it never made it into the OS.
I rebooted, went back into TWRP with plans to redo the procedure, only now the microSD card slot is not being picked up. I tried multiple micro SDs of different sizes (1GB-32GB), I've tried inserting before boot up, inserting after bootup, inserting after bootup and then rebooting the device. No luck.
I bought a USB adapter that plugs in where the power plug goes, hoping I could run the files off a USB flash drive. or a micro SD card within a USB flash drive. No luck.
I am running Teamwin's TWRP 2.3.2.3
My backup from nandroid happens to be on my microSD card too. So I can't use it to recover the old OS either.
TL;DR: Micro-SD card stopped working after a failed attempt to flash an OS. OS and backups are on the microSD card. PC recognizes the device but won't let my access the hard drive.
Does anyone have any suggestions on what to try?
Thanks!
Well, the USB is not set up to be mounted in recovery. Keep in mind, the microSD is mounted at /sdc/ in TWRP.
You can always use ADB and push a file to the internal (/sdcard/) so you can flash if your microSD slot is dead.
Let me find a post on how to do this.
EDIT: Here is what to do if you need to use ADB:
Plug tablet to PC via USB
It should install new hardware and show 1 devices, an ADB device.
Update the driver in the Device Manager on the windows machine to the Naked Drivers
Once that is updated, I downloaded ADB from the Android SDK. You really only need three files, available here: http://db.tt/b9dQ6xzp
Unzip these files to a folder called c:\adb
Open a command prompt and type the following:
Code:
c:
cd c:\adb
adb devices
It should show a device connected. It may error out when restarting the daemon, but keep trying and see if it can find your tablet.
If you cannot get the ADB driver installed or updated, my guess is that you have a bad USB cable. Yes, it IS possible to have a bad cable for data transfer that STILL charges your tablet. I have even had that happen to me.
If you got this far, then here is what to do next:
Download your favorite ROM. If applicable, save any other files needed (GAPPs or kernel)
Save this at c:\adb\ROM.zip. Other files save accordingly like Kernel.zip and GAPPs.zip.
Next, run the following commands
Code:
adb push ROM.zip /sdcard/
Once this competes, you will need to repeat for any other files to flash like GAPPs or Kernel.
After these files have been transfered, you can install a file from the internal (/sdcard/) directory.

After these files have been transfered, you can install a file from the internal (/sdcard/) directory.

Thanks so much frederuco! I will be trying this later today and will update this post as soon as I do.
I just wanted to say good luck, and we are all counting on you.
Almost there!

The update! I followed your instructions, while on the cmd prompt, I got no confirmation that the files were moved, but they appear to be on the device now. When I go to reinstall through TWRP, the flashing fails. I am going to do some digging around the forum to see what solutions there may be, but if you (or anyone reading) has an idea, do tell.
I will be sure to update this thread if I fix it, including the solution I found.
Try downloading the ROMs again.
Also, note that I edited my reply as I had said ROM.blob and it should be ROM.zip.

I think I'm in good shape. I tried to edit my post from earlier, but I had to wait a few minutes before it would let me.
I realized the file didn't finish transferring to the tablet. Moments after my last post, I got a confirmation from cmd prompt that the first file finished. The second one just finished, and the third is still transferring I suspect. That would totally explain the failure.

Alright, so I got past the logo, Android upgraded all the Apps and is now "Starting apps" .. it's been here for about 10 minutes. I think I can take it from here.
The ADB push was the solution.
Waited another 15 minutes. Nothing happened (stayed at Starting apps)
Restarted device. Booted up as it should and I am now all set. Thanks again!
Now that you're using EOS can you use the microSD slot? I know moving from stock to EOS fixed my card slot issues not to mention that I'm loving the Jellybean goodness

I'm fairly certain the slot itself is broken. Haven't been able to get it to read things yet.
I'm still having some minor issues with the setup, but I know I've seen fixes to these problems when browsing this forum. Google Search/Google Now crashes 3-4 seconds after opening it. The system also reboots "randomly" (really, just when it's idle for more than 10 minutes), I also had to go into TWRP last night to get the system to power down. Long pressing power and selecting Power Off simply rebooted it.
But compared to where I was 24 hours ago (and had been stuck there for 1+ week, I really didn't want to burden people with my problem since I'm a lurker here), I really can't complain and have full confidence that I'll be able to get the kinks worked out.
At least I have an adapter for the power port, so I can plug USB sticks (or USB-microSD adapters) into the tablet still.

The workaround for Google Now crashing is to disable Hotword Detection in Settings - Language & Input - Voice Search (or something like that). Search the EOS thread for "Hotword" and you will find the location.
Do you have a SD in the dock? This can cause SOD and RR's.
Hmm, I guess I have never tried powering down on EOS, but I am pretty sure it works. I just put my tablet to sleep and never turn it off. I find my tablet (even undocked) will lose more power when it is off than when it is sleeping.

Nope, nothing was in the dock. I actually didn't have the keyboard dock plugged in during the "crisis"- I did try getting TWRP to read a card from it once, that was about it.
I read somewhere else, that once you let the battery die on it's own, and recharge, the "never powers off" issue goes away for many people (haven't seen one specifically relating to EOS on TF101, but the other symptoms were spot on)
I'll be checking out the Google Now tweak in a bit.
I'd been running a custom kernel on my Transformer since about a week or two after I bought it at a Black Friday sale simply because it would keep running on the stock ICS ROM. Changed to KAT kernel when I moved to EOS. You might want to consider a custom kernel if you have a Transformer that suffers from the reboot issue like mine did.

You may want to try doing a full format in TWRP, and using the superwipe full scripe from the ARHD thread, then formatting again, wipe cache and dalvik, push the latest EOS, KATkernel and Gapps to the device, wipe dalvik cache and cache, flash EOS, wipe dalvik cache and cache, boot into the ROM, boot back into twrp, wipe cache and dalvik, flash Gapps, wipe cache and dalvik, boot into the ROM, boot back into TWRP, wipe cache and dalvik, flash KATkernel, wipe cache and dalvik, cold-boot into the ROM.
That should set you up with the most stable your tf is going to get, it seems erroneous and like a ton of work, but I strongly believe in doing this whenever I flash a new rom setup, I've gotten to doing it in about 10 minutes now.
Just an update.
EOS's random reboots were getting pretty bad. Happened a few times while I was working on a few docs (thankfully Evernote had autosaved)
I also noticed when the screen would go off, it would eventually turn back on and attempt to reboot, getting stuck at the Asus loading splash (pre EOS logo). I ended up re-flashing with my newly gained leet adb skills (thanks frederuco ) and went with Cyanogenmod 10. I've only had 1 random reboot since and Google Now seems to work 90% of the time.
I'm sure there are some more things I can do to fine-tune it, still getting a hang of everything.
Thanks again for everyone who's helped.
begonia (Xiaomi Redmi Note 8 Pro), MIUI 11.0.6.0
I had an unfortunate series of events that resulted in a booloop. Basically:
- Magisk suddenly stopped working one day, after 1.5 year of no issues. I did nothing related to it recently, except just using root functionalities in e.g. Tasker
- I flashed newer Magik 23 and also updated TWRP fom 3.3.1 to 3.5.2
- everything worked fine up until one restart, which resulted in TWRP encryption problems. Right before restart I'm pretty sure I installed Viper4android. I could still get into system with a workaround of TWRP's "Decrypt user" hanging into button reboot, but Magisk/root wasn't working anymore
- so I thought reflashing Magisk and dm-verity/forceencrypt would help, but here's where the bootloops started. During the flash attempts I saw some partition mounting errors since the device was decrypted, so maybe that caused some data issues?
I tried now:
- downgrading TWRP to 3.3.1 - decryption works fine in it and I can flash problemlessly from it, however, doesn't help with bootloop. Reflashing Magisk/dm-verity zips from it also didn't help
- flashing recovery ROM (the same MIUI I had - 11.0.6.0) changed nothing
- flashing fastboot ROM in MiFlash with "save user data" option changed nothing, except I guess confirming the issue is with data
- last thing I tried was flashing uninstall.zip for Magisk since that removed its data folders, which I thought may have got corruped, also to no avail
I know it would probably get fixed with data wipe, but I need the data - I have hundreds of apps with lots of configuration for permissions, notiications, etc. and my recent backups from few months ago vanished because SD card got lost. I have a TWRP 3.3.1 backup of the data now, too bad I didn't do it before updating Magisk/TWRP - lesson learned... So the question is - what can I still do to further debug and fix this without losing data?
I read that reading these logs may also help with debugging, but not sure what to look for.
Kernel log (/proc/lastkmsg): https://pastebin.com/T2xBBRvi - some error looking lines at the end, but non-comprehensible. Can I use them somehow futher?
dmesg log: https://ghostbin.com/paste/vyBDk - don't really see anything here, but it's quite long and not sure what to look for
logcat: https://ghostbin.com/paste/PSh7f - lots of "avc" errors
Please help
Bump. Any help would be appreciated
Plug in the USB cable with the phone powered off. Then issue the commands
Code:
adb devices
adb wait-for-device
adb logcat
from your Windows CMD or Linux terminal: it will hang waiting for the device to come on-line, now power up the phone. The logcat should start scrolling off then.
While it's turned off:
Code:
$ adb devices
List of devices attached
mfaajbdu5s79pfhy unauthorized
If you `adb wait-for-device`, the cmd just waits and you can't enter next command.
`adb logcat`, if I skip the above, waits for device itself, but nothing happens, it just restarts to TWRP and the commands still hang. I can use logcat while in recovery though, that's what I did above
Ok, so I just went ahead and tried the following, too:
- made sure the TWRP data backup can get restored, just in case
- wiped data through TWRP, still the same (re)bootloop into TWRP. I tried both factory reset and advanced wipe with Dalvik/Data/ntenal Storage/Cache.
- so I tried reflashing 11.0.6.0 using MiFlash with that erasing data. That at least worked and phone boots after doing this, but unfotunately not what I'm looking it
- I then tried to get TWRP 3.3.1 back. I got into that and the usual rooting steps were invalid - recovery_fromboot ile was not present in system_root/system. Maybe that's not just present in downloadable ROMs? No clue, but doing the rest of required rooting steps - Magisk 23 install -> Close AVB (TWRP action) -> Remove dmverity (TWRP action) resulted this time in infinite type of bootloop, not sure why, waited for over 30 minutes
- so I reset into TWRP and tried flashing the dmverity zip that's from xda. And this is definitely what caused previous (re)bootloop as after flashing that its more or less the same time length before boot stops and restarts into TWRP. Now, weirdly, while installing this there was an error this time, saying that nvdata cannot be mounted
So I guess the problem before was with mounting nvdata? I see it's something related to phone's IMEI. How does it work exactly, is it somehow related to /data partition? Why wouldn't it mount? Why does it work with pure standard flashed ROM? Is it supposed to be empty when you look at it with TWRP's file manager? Could be something else but this is my only clue right now...
EDIT: oh, you can mount it in TWRP and that works fine, it's not empty. Not sure why that install scipt suddenly stated claiming it can't be mounted, by the end of log, though.
Completely no insights?
I'm coming back to the topic after almost 1 year on old backup phone because I got depressed by this incident and couldn't continue working on it. The old one is like 6 years old, it has abysmal battery life, it ran out of space and I can't install certain apps on older Android, I'm also missing a lot of the set up that I had and which was pretty convoluted - with Tasker and lots of other heavily configured apps. Which slows me down each day.
I can bring the new phone into usable state anytime, a matter of less than hour and reflashing the soft completely, however, setting it up initially took me one year of almost daily changes, many of which can't be retraced as my Titanium backup is old for some reason and there were a bunch of root related changes.
So any sort of help as to how I could potentially recover it with the data would be really appreciated.
And bump
Let's try a bump again
And one more hopeful bump. I'm even willing to pay/donate for any useful insight that will lead to progress with this as my old backup phone is becoming unusable and I don't want to start setting up this one from scratch again.
One last bump before trying in a new topic.
TLDR: what's the best way to debug a bootloop? Do the logs above help or is there something else?

Titanium backup is now broken, at least the recovery is now broken. You also are not allowed to start duplicate threads.
Titanium backup doesn't really help me anyways. And ok, I guess I'll keep bumping it then...
Can you access fastboot?
