[Q] Boot Loop After Flash

When I got my G tablet yesterday and rooted/flashed to 2.2 Lite, I did it using my G1's SD, but since then I backed up my SD to what I had it on my G1. My question is, can the G tablet naturally boot from an SD card(micro) as long as its named update.zip? I mean so I can do the flash again or is it perma bricked? If it is perma bricked, should I return it to store and start all over with a dedicated SD card?
Thanks!

Necro,
This tablet is 99% unbrickable (I would say 100% because I haven't head of one bricked yet but nothing is impossible). you just need to boot into APX mode and reflash stock firmware
how to get into APX mode can be found here
http://wiki.tegratab.com/index.php/Nvflash_FAQ
you are going to need to download the complete NVflash restore file
which can be found here: http://forum.tegratab.com/viewtopic.php?f=13&t=18

The download link for the SDK is broken or old. Is there another place I can download it. Stupid google keeps bringing me the PDFs for Nvidia. Nevermind about the SDK, found it on their site. What about the original ROM/IMG? That link is also broken.
Is there a better guide. I'm getting a headache from all the files the SDK dumped onto my computer. Can someone show me a noob proof version of how to do this?
I only undertand the APX mode on the G Tablet. Other than that I cannot get windows to recognize the device even after installing the SDK. Where are the drivers for the APX?

There are instructions on the main post for TNT-Lite for what to do if you get into the boot loop. I ended up having to get to the step where I repartitioned the internal flash and re imaged.

You can avoid the SDK and driver issues and only use the computer to put some files on the SD card:
Easiest way to fix for me was (I had same issue problem with 2.0):
1. Download "Clockwork .8" (links at XDA)
2. Unzip the recovery file and update.zip to root of a micro sd
3. Change the recovery folder's command file to "microsd2" & save it
4. Put the card in the Gtablet
6. Interrupt the boot loop by pressing power and volume up at same time
7. Clockwork should install
8. Power down and restart the G tablet
9. Download TnT Lite 2.20
10. Repeat 2 and 3, but this time extract the update.zip file from TnT 2.20 and copy over the update.zip already in the root directory. YOU WILL NOT NEED A RECOVERY FILE FOR THIS METHOD.
11. Delete the recovery file in the root directory
12. Power down
13. Restart by pressing power and volume up
14. Should be in Clockwork
15. You want to clear both cache and data (two options on main screen)
16. After clearing both, choose install update.zip.
17. The next screen will show the update.zip. Go to its row and choose it by pressing home button
You should auto reboot and be set. You can then install the Folio Flash apk and install Titanium so you can do the market fix.
This is process is what saved me, at least.

Did not work... I might go and return it tomorrow. I even tried flashing to original firmware and nothing.

I got stuck in an unrecoverable boot loop as well. I tried to install TNT Lite 2.2, got a boot loop.
Tried to install TNT Lite 2.2, 2.2.1, 2.3 from microsd (yes changed the line to SDCARD2), always got the giant exclamation mark.
Tried to install the vanilla restore and stock TNT from here http://forum.xda-developers.com/showpost.php?p=9439414&postcount=7 still exclamation mark.
Tried to install Clockwork Mod, still exclamation mark.
EDIT: Finally got out of my bootloop by flashing the ViewSonic G-Tablet Restore file from DroidPirate
http://www.droidpirate.com/download/click.php?id=1777
http://droidpirate.com/category/ablets/viewsonic-gtablet/
Its the only one that worked.

PC does not see TF101 B40

HI,
2 of my PC (Windows 7 64) does not see my transformer in USB Debug mode. I installed the 64 bit Dell driver on each PC. Could someone provide me with some options to try.
Is there a way to completely reset the Transformer to stock without USB or being able to load a kernel from SD card?

2 ways to reset -
If you can boot then go into settings --> backup and reset --> factory data reset.
If you can't, hold volume-down then press power, and wait till wipe data appears, use vol keys to select it.
and search for the Universal Naked Drivers, those may help.

Thanks. That seemed to wipe the user settings and data, but not the recovery app "CWM-based Recovery v5.5.04 roach-tf101-r2". As a result the following happened after I reset.
System reboots
System comes up clean and runs setup (wifi, gmail account, etc).
System downloads firmware update.
System reboots to install update
Android appears and runs for a few seconds
Mesages appear: CWM-based Recovery v5.5.04 roach-tf101-r2
Finding update package, opening update package, Verifying update package
E: failed to verify whole-file signature
E:signature verification failed
Installation aborted
At this point the TF still will not install zip from sd card since as you told me before I need a different recover and is not found by the PC with a naked driver.
However, the unit is functional.
Any other options to root and get a new recovery installed and finally a new ROM.
Note: the PC does see the TF if I am in the recovery. However, as soon as boot the TF and enable USB debug the TF us not seen.

To go back to totally stock including stock recovery, download and flash an official ROM from Asus website.

I have no problem doing that, but how do I do it if I cannot connect the TF to PC via USB or load a zip file via recovery? Both of these do not work!

Did you update cwm via ROM manager? That's the issue there, you can run Roach2010's fix to fix that.
If terminal emulator app works you can flash a downloaded and extracted
(through es file explorer) recoveryblob with
Code:
su
dd if=/sdcard/recoveryblob of=dev/block/mmcblk0p4
reboot
Then you have working recovery and can either flash ROM or Stock.

Thanks for all the replies.
I finally got it working. It took me forever to understand that having a recovery that could only read from the internal memory was not a big deal. I created a folder on the internal sd and dropped in the zip for the external version of CWM . I rebooted and loaded the new restore and from then on I could load ROMs from my external uSD card. I am now happily running the latest version of Revolver.

[Q] Stuck in Android system recovery <3e> & need help (Newb)

I tried to install clockworkmod recovery on my Sprint Samsung Epic 4g, and tried to root it, in preparation for flashing a custom rom. I failed. Please help me.
Instead of describing exactly how I got the phone into its present condition -- I don't think I could do so accurately -- I will, for starters, describe the present condition of the phone.
When I power on, the phone boots into Android system recovery <3e>. Must remove battery to turn it off.
After removing battery, I can boot into Android system recovery <3e>. In this recovery environment, I did a wipe data/factory reset and wiped the cache partition. If I select the reboot option, the phone restarts but hangs on the initial Samsung screen.
After removing the battery, I can also boot into download mode.
After removing the battery, if I plug in the micro usb from the wall charger, or if I connect the micro usb from my pc, the phone boots into Android system recovery <3e>.
Is this a hopeless situation? Or, can I install clockworkmod recovery, root the phone, and flash a custom rom?

You have failed to explain what exactly you have done to root your phone, especially since there are different methods of doing so, and without your explanation, no one can you help you.

Please try to be patient with me. I will recount what I did to the best of my ability to remember.
I began with the Samsung_Epic_4G:_Full_Update_Guide on the cyanogenmod site.
I'll quote the guide and, along the way, I'll indicate what I did:
"Download DRockstar's ClockworkMod Recovery, and the Heimdall Suite:
DRockstar's ClockworkMod Recovery: download
md5: 9ae119a8202d594226e88796dfb8d0c2
Windows:
Heimdall Suite 1.3.2: Download
Windows ONLY:
Power off the Samsung Epic 4G and connect the microUSB to the computer but not the Samsung Epic 4G.
Boot the Samsung Epic 4G into download mode by holding down the 1 key on the physical keyboard and Power.
Connect the microUSB cable to the Samsung Epic 4G.
Run the included zadig.exe in the drivers folder of the Heimdall Suite.
From the menu, choose Options » List All Devices.
From the drop down, select Samsung USB Composite Device or Gadget Serial.
Click Install Driver.
NOTE: A prompt may appear warning that the installer is unable to verify the publisher of the driver. Ignore it and select "Install this driver anyway."
Heimdall can now be used safely on the Windows computer.
Power off the Samsung Epic 4G and connect the microUSB to the computer but not the Samsung Epic 4G.
Boot the Samsung Epic 4G into download mode by holding down the 1 key on the physical keyboard and Power.
Connect the microUSB cable to the Samsung Epic 4G.
Untar DRockstar's ClockworkMod Recovery into the Heimdall directory.
On the computer, open terminal and run the following command from the Heimdall directory:
heimdall flash --recovery recovery.bin
A blue transfer bar will appear on the phone showing the recovery being transferred. The device will reboot automatically.
The Samsung Epic 4G now has ClockworkMod Recovery installed. Continue to the next section."
I completed all of the above steps successfully. Next, it says,
"Flashing CyanogenMod
NOTE: In order to flash CyanogenMod via ROM Manager, root access is required. Attaining root access is outside the scope of this wiki page.
If the Epic 4G has been rooted, unlocked, etc. through steps other than the method described above or running a custom ROM other than CyanogenMod and you are having issues flashing or booting CyanogenMod, it is recommended the Epic 4G be returned to stock & start over with the full instructions provided above."
At this point, I decided to root the phone so I could use rom manager to flash CyanogenMod. I used the root samsung epic 4g at the androidauthority site to try to root the phone. I was able to complete all of the steps, that is:
Download the rooting package (SamsungEPIC4GRooting-Kit.zip, 6.48 MB) from here to your PC.
Extract the downloaded ZIP file using any extraction software such as WinZIP or 7-Zip. You will get 3 files; place the extracted files inside a single folder.
On your PC, launch the Odin application by double-clicking the odin3 v1.85.exe file. This should launch the Odin3 application on your PC.
Switch off your Galaxy Epic 4G.
Boot into Download Mode. You can do this by pressing the number 1 key on your phone while turning the phone on.
With Odin3 running, connect your phone to your computer via USB cable.
Odin3 will automatically detect your phone. If successful, the word “Added!” will appear in Odin3’s message box.
If you don’t receive any message, you need to install or reinstall the appropriate device drivers on your computer. Also make sure that USB debugging is enabled on your phone.
Select the PDA tab in Odin3’s user interface. A dialog box will appear, asking you to browse for a file. Browse for the extracted .tar file; in this case, select acs-eb30-clockwork-epic-touch-4g-sep-20-4-00-pm.tar.
Make sure that you do not change any other settings in Odin3, as it may cause irreversible damage to your phone.
Select the Start button in Odin3 to start rooting your Samsung Epic 4G. It may take about 2 to 5 minutes for the whole rooting process to finish. If rooting is successful, you will get a “PASS” message in Odin3’s message box.
Disconnect your phone.
Congratulations! You have successfully rooted your Samsung Epic 4G SPH-D700. Enjoy the many benefits of having a rooted device such as installing custom ROMS, mods, hacks, and themes.
Next, returning to the cyanogenmod wiki (Samsung_Epic_4G:_Full_Update_Guide). I did these steps:
Downloaded the latest version of CyanogenMod.
Downloaded the Google Apps for the device.
Placed the CyanogenMod update.zip file on the root of the internal memory.
Placed the Google Apps .zip on the root of the internal memory also.
The next step was to Boot into the ClockworkMod Recovery.
When I tried to do so, I think I got into the <3e> screen that I described in my first post.
I Selected the option to Wipe data/factory reset.
Then selected the option to Wipe cache partition.
Next, Selected Install zip from sdcard.
When I tried to do that, however, I got an error saying the file signature was not verified.
That's how I got stuck in the <3e> recovery mode.

What you have done is used an article that is say, out of whack. If you looked in the comments, you would see that others have failed with that method or their phone broke, which leads to this video: http://youtu.be/QTQ6Rn0FBSk
You could have used that video, but here is where you screwed up even more..
You downloaded the CM and Google apps zip to your internal memory when you were supposed to placed them into the root of your SD card. And to add on to your mistake, you already wiped your system, cache, etc. without backing up your current ROM..
You already wiped your system and such, and I honestly wouldn't know where to go from there.
However, I can lead you to this video: http://youtu.be/QTQ6Rn0FBSk to unroot (possibly unbrick your phone).
And I can give you this link: http://forum.xda-developers.com/showpost.php?p=28080049 because someone has had the same problem as you do now.
With that, Best of luck to you and your phone!

Happy New Year!
Please note: I placed the zip file on the external sd card. I just checked the external sd card with the card reader on my pc, and that's where the zip file is. I mistakenly remembered putting it in internal memory.
Does that make a difference in the advice you gave me?

GOOD NEWS! Using the link you sent to me for the you tube video, I returned my phone to FC09.

Glad I could help [just a little]. :good:
Extremely late, I know.

upgrade to CWM 10.1 caused my device to FAIL..need help!

Hey whiz kids,
I upgraded to a new NIghtly cm-10.1 for my tf300t through the custom roms app. Problem is I didn't have a upgraded bootloader, it could be as old as honeycomb I don't know. Whats happening now is a the first Asus screen loads up and its just frozen there permanently until the device dies. I can get into RCK and Fastboot. Apparently I don't have a backup either. What are my options?

Whoops, sneezed and clicked the Thanks button. Oh well... you have my thanks.
Load a stock ROM on you microSD (available on ASUS' support website), and flash it from recovery. This should update your bootloader in addition to flashing a bootable ROM. Then, reflash CM's nightly.

It might be better to ask in the 300T section in case there's any slight idiosyncrasy's that differ from the TF700T.
Marty is right though you should be able to flash back to ICS and start over with an unlocked bootloader.

Appreciate the comments back..thanks. I tried the suggested idea, however, the microsd card inserted on the side of the tablet doesnt have an option in recovery to open up and view the files. The only option I have is to look through the internal usb storage drive, since I cant connect the tab to my computer in an way I tried so far, I cant get an old rom into the internal drive.?? Its just frozen on the asus bootloader screen and wont even turn off lol.

Hold down the power button long enough will enventually turn off the device. Make sure it off first then boot into recovery and see if you can access your sdcard. If not working hookup usb cable between pc and your device, boot into recovery (home page), then open adb on your pc and make sure the rom file is in the same directory of your adb command, on your pc run this command to copy file to your internal memory:
adb push c:\folder_where_adb_and rom_zipfile\rom.zip /sdcard

OK..I sent the file using adb push it took like 90secs and it confirmed the asus jellybean firmware (10.4.2.16) file at 100mb. Only problem is is that its not showing up in the sdcard. There are just a bunch of folders with no new .zip files.?? I dont understand why the file wouldn't show up after it says it sent it.

Which custom recovery are you using? Sounds like you need to re-do it from a PC when in fastboot mode ( choose USB icon in boot loader ). Make sure you use the latest TWRP or CWM as they both read the card fine.

If you are at RCK what happens when you press then release (and wait) volume + (up)?

Shamelessly ripped from Pretoriano80's excellent summary thread from here:
http://forum.xda-developers.com/showthread.php?t=1833212
I copied it here because I wanted to point out the rename step that's needed if you're on stock recovery somehow. I too am curious as to what recovery is active on your system...
*** Factory Restore after a softbrick/Downgrade from Jelly Bean to ICS/Clean Factory Restore ***
When You Need This?
* if you get stuck on Asus boot screen (the one with the spinning wheel)
* If you don't like JB and you want ICS back
* if you want to get back to a clean stock firmware
Note: You need to have a working recovery (stock or custom) in order to use this method.
========= Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with stock recovery =========
1) Download the latest firmware from Asus site (based os your SKU,eg. ww 9.4.5.26 * to downgrade from Jelly Bean you need the 9.4.5.30 firmware)
2) Extract the .zip file somewere on your desktop (the result will be another .zip file,use it for step 3)
3) Rename the extracted archive to "EP201_768_SDUPDATE.ZIP" (without the " ") and upload it to a MicroSD card
4) Insert the MicroSD card in your tablet and use this button combination to Power ON and go to recovery --> Start the tablet by pressing Volume Down and POWER togheter for 5 seconds ,a message will inform you that you have 5 seconds to enter the recovery,press Volume UP before the 5 seconds expire.
At this point the device will go in recovery and should start updating your firmware .
Note: Keep in mind that Windows doesn't show the known file extensions so most users don't have to put the .ZIP extension in the filename.

Phone stuck in Cyanogen boot logo after trying to flash CM12.0s

It's been a rough morning over here.
I've had a lot of issues with the latest update (12.1) so I decided to download the .zip for CM12s and install it from recover - the exact same way I updated it initially (before I got the 12.1 OTA update).
I used the same .zip file from before, builds.cyngn.com/cyanogen-os/bacon/12.0-YNG1TAS0YL-bacon/2263178b74/cm-12.0-YNG1TAS0YL-bacon-signed
After installing from internal storage from the menu, it seems to install fine, and then it takes me back to the menu and I select Restart System.
After 20 minutes looking at the Cyanogen boot logo, I'm assuming it's stuck.
When I plug the phone into the computer, it says it's charging but neither Windows or my Chromebook recognize the device to allow file transfer.
If I press down+power, I can still get to the Cyanogen menu, but without a new .zip file I'm not sure what else to try.
Any advice? I'm pretty worried!

Have you tried using fastboot to flash the stock images?

Are you using twrp?
1.I suggest installing twrp vor any recovery you like.
2. Than redownload rom and gapps (just to be sure)
3. Mount your device as mtp storage in twrp and put Rom and gapps in it
4. Than wipe /system /data /cache
(data wipe will delete all apps, your internal storage will be untouched)
5. flash rom and gapps
6. reboot your phone
If that does not help try Heisenbergs solution.
