Can't access recovery - Transformer TF300T General

HI,
After manually trying to upgrade my TF300 into the latest version,
And trying troubleshoot it by myself, I can't access the recovery anymore.
It got stuck with no progress and I have to perform hard reset of my device.
Any idea how can I fix it?

Guys,
Any recommendations?
Thanks!

This is not enough information. Advise what state you were in before. Did you have recovery before? What update did you attempt? Are you on jb or ICS? Include versions when describing what you're working with when talking Roms, recovery, or other updates.

Hi,
Thank you for your answer.
I'm running root and unlock 10.4.2.9 ww version.
I'm using voodoo to keep my root rights, and cw 5.8.34 to access recovery.
Every time I'm trying to access recovery,
The tablet freeze right after choosing the RCK option.
I'm not sure what did I do that might have caused that.
Apparently, after removing some of the built in applications, I cannot simply upgrade my tablet to the latest version, so I had to try few workarounds, but it seems like I had few mistakes...

You could try to reinstall the recovery (which one were you using : twrp or cwm ?).
Best option is probably twrp2 (follow instructions at h t t p : / / teamw.in/project/twrp2/97).

I'm going to have to agree with this being the best option.

Wow,
After replacing the recovery as per your suggestion,
I can open the recovery and even upgrade the version into latest version (10.4.2.13).
Thank you very much!

You should always make a nandroid.
You downlaoad the latest arhd and super wipe first.
Go to recovery mode
Flash super wipe first
Then arhd
Then reboot device

I am also about to load Android Revolution on to my stock 8.6.5.21 (HC3.1) non-root.
But I would like to either backup or download a copy of the stock ROM 8.6.5.21, (apparently the last working stock ROM) before proceeding.
However, no stock ROM 8.6.5.21 can be found on the Asus website. AFAIK, ROM backup tools require root, which I don't have. If I root, that would change the rom before I can backup.
I need some suggestions.
up, any ideas?

It's serious: I need help... flashing stock A501 rom

Hi,
atm, I have an A501 with CWM-based Recovery v5.5.0.x(thor2002ro rev1.7) and Android 3.2 (EMEA CUS7 - Germany).
My Tab tells me that there is an update, which I downloaded and tried to install. However, after a few seconds an Android with a red exclamation mark appears and the installation of the updates aborts.
So, I want to remove CWM Recovery and root and return to a stock rom. However, that seems impossible. I downloaded the Acer Recovery Installer App but this one offers me a USA A500 stock rom - but I need an A501 rom because of 3g.
When I try to install this one (http://forum.xda-developers.com/showthread.php?t=1234039) I decrypted before, CWM tells me
"Installating update...
Installation aborted"
So, this does not work either.
I am really desperate because I have to revert to a stock rom...
Can someone please, please, please help me out?

The update has overwritten yr custom recovery with the Acer stock recovery. It also checks yr system files if it ain't completely stock it will abort. being rooted can also affect the update.

Yes, I did install cwm again from acer recovery installer, but that did not change anything.
Unfortunately none of the roms offered on xda work, they all abort in cwm and I don't know why.
I would prefer to go back to a stock rom with stock recovery because I want to give the tab to someone else.

Yeah, you may have difficulties flashing full packages via CWM. Especially if you didn't decrypt the rom first.
I've got a few 501 roms you can try. All HC 3.2.
One of them, is an ATT full package update which will probably work for you. Just pull the update.zip out of it. Put it on your Ext SD card, and boot holding PWR and Vol+. This will force it to install update.zip from the SD card.
Any rom you use, you have to decrypt it first. Some try renaming the rom to update.zip, and some have success using this method.
Like I say, it's an AT&T rom, but is probably really a ComGen 1. So it should have decent language support.
If you're interested, I can throw them up on a server tomorrow.
But I tell you this first, before you go messing around with these things. GET YOUR UID Number first, and write it down. You can get instructions on UID in the Development Forum, 1st page usually. It's easy.

U must use a "update.zip" , decrypted first as Moscow said, and booting into recovery via button combo may help too,
also remember to remove the zip file off the ext. sdcard when you are done!!

[Q] Booting into recovery shows "no command"

Hi there,

Today booted and also flashed the new CWM recovery image but now, when booting into recovery only get an android logo and the text "no command" ?
Any ideas ? Flashed back to original recovery image but no change either ?
Root remains though and working fine.

From efrants android 101 sticky:
I just flashed CWM, but every time I try to boot into CWM, I keep seeing the stock recovery. Why?
If you updated your Android build using an OTA update file (either manually or over-the-air), the update placed two files on your device that re-flash the stock recovery every time you reboot your device. These two files are:
/system/etc/install-recovery.sh <== this is the script that installs the patch file
/system/recovery-from-boot.p <== this is the patch
You have to rename (or delete) one or both of them, then re-flash your custom recovery. Now it will stick.

Perfect! Thank you! I had just previously downloaded 4.2.1, and so renaming recovery-from-boot.p did the trick. I had to remount my /system as read/write (used Total Commander, and it worked like a charm.

[Q] How to Downgrade to 4.1.1 or Original for TF300T???

Hey guys!
I am trying to downgrade my current Stock 4.2.1 Rom to either 4.1.1 or 4.1.2 either stock or custom if possible even factory original.
How would I go about doing this as there is no clear cut instructions I could find....not sure if I can use NVFlash???
I previously had root performed using the VoodooOTA Method. Now I have unlocked the bootloader and also managed to install the TWRP Custom Recovery....although I do not think it has been installed correctly as it is unable to mount certain directories...../cache or /data and /system are some examples.....not sure if that is because of version or because of changes done to root enabler by new firmware upgrade.
If anyone has clear instructions or could point me in the right direction I would highly appreciate it!
Thanks
There might be a few issues with the new OTA update and recovery, if you already have a backup with nvflash from when you had ICS then yes there is a guide you can use to go back,
http://forum.xda-developers.com/showthread.php?t=1894867
if not then you should either try to flash one of the stock ROMs mentioned in the sticky in the Android Development section
http://forum.xda-developers.com/showthread.php?t=1697227
or if you think twrp is not working well you should wait just in case you do damage to your device. There is a chance some partitions have been altered in the new update and twrp needs to be updated, by whoever is responsible for our version, to be able to function properly.
If the reason you want to go back is the launcher then there is an option to switch to the 4.1 launcher in the options, not sure where exactly but if you look a bit further down in this section you'll find someone else posting something about it.
And a last suggestion is that when you have a question better post it in the appropriate section

hahahaha! funny u mention that coz i think I screwed up :silly: ...What I did was download the official bootloader from the Asus Website ASUS Transformer Pad TF300T Firmware: V10.4.2.20 Only for US SKU (Android 4.1) and use fastboot to flash the blob file.....now the only thing it does is spin at ASUS (boot loop)....The funny thing is it did affect how the fast boot option loads though it now shows up with the option of USB....and does not automatically go to fastboot.....my comp recognizes both in fastboot and adb the device so there is something......just performed a cache and dalvik wipe but to no vail and prior did a fix permission.....ALSO I do not receive any error with regards to mounting like before....

I am pretty sure he said that he is unlocked and running twrp, you can flash whatever rom you want from recovery but it will not bring back the ICS bootloader and the ability to have NVFLASH or even the 4.1 BL, so in reality he flashed a new rom and not actually downgrade to the previous state of the tablet.

That is actually correct, I dont know if itwill work in general but I previously had my OS rooted and backed up using Voodoo OTA Rootkeeper. The only thing that I did new from here on is
1. Backup an Nandroid using ADB Terminal Access -
Code:
adb backup –apk –shared –all –f C:\Android_Asus_4-2-1.ab
Ofcourse in-order to perform this feat you would need Android SDK Tools Package and Google USB Drivers installed on the drive
2. Perform the unlock bootloader using the apk found on the Asus Website
3. Flash Stock Rom that can be downloaded from Asus or here
using fastboot
4. Flash TWRP for JB using fast boot with help of link
5. Go into recovery Wipe Dalvik and Cache and Factory Restore
6. And boot!
Okay I know this is no GUIDE as I am press with time....I will try to make a proper one. but in all honesty I would just wait for the REAL DEV's to post the solution to 4.2.1

Hi,
I need to downgrade my tab as my touch doesn't work and need to flash other firmware it. It was told to me to downgrade and it should work, but was said I need TWRP because with CWM I could brick my tab. Without touch it's impossible to use TWRP. I have ulocked bootloader and rooted. Your guide doesn't seem to need of use exactly TWRP as Wipe Dalvik and Cache is worked when I rooted tab.

noob here, lost at rooting

hey all,
I'm a complete noob when it comes to rooting
I've been searching online on how to root a nexus 4 using a mac.. every single guide is different, some skip the unlocking bootloader part, some skip other parts, and most guides are just outdated.
I'm running on absolute stock, 4.4.2.
What's the best (and most current) guide out there? I'm interested in rooting my phone mainly so I can get LTE access.. do no care too much for non stock ROMS (not yet at least)
I think this is the easiest for noobs: http://forum.xda-developers.com/showthread.php?t=1999065 . It's a tool that will do all the work for you.

so now I'm confused about the whole Rom part.. which one do I download? There's a ROMs column, a stock recovery, and stock touch recovery. What are those?
You don't have to install another ROM. You can just download the recovery (CMW for mako touch or non touch) in the post. Also download the su zip tot get root acces.

ah, so the touch column is all the 'stock' roms. how do I know that it's the latest 4.4.2 stock rom? will be able to do OTA updates after I flash the mako touch?
If you're device is rooted I think you won't be able to install OTA updates from google anymore. But, you can flash these stock roms easily. I'm sure people make flashable zips of every new version of Android. About the columns: ROMs=you can download custom roms (you don't need that); Recovery and recovery touch is basically the same thing. The difference is one recovery can be controlled with the touchscreen and the over with the volume and power button. It's just what you like best.

Cwm(clockworkmod recovery) is a side load which helps u to flash different ROMs and zip files. It also helps u to wipe battery stats, partition sd card(not with case of n4)
Factory image is the stock ROM that Google provide that u r having in your nexus 4

And regarding your previous question of OTA updates, You'll have to flash the stock recovery if you're on CWM or TWRP (Team Win Recovery Project - Many people recommend this one, I use it myself) and you shouldn't have made any changes to the system files of your stock ROM.
You will receive the OTA if you have modified anything in system, you just won't be able to flash it. And you can also flash the OTA with TWRP instead of stock recovery. Root does not matter, although it will be lost after you update. Before updating, also make sure you're not using a custom kernel. Kernel: The "thing" that android runs on. It's the heart of the OS, you could say. No kernel, no boot.

So let me make sure I'm following this..(sorry, I'm sure you saw such questions countless times before)
CWM (or TWRP) is a custom recovery instead of the stock 'recovery' option that's found in the bootloader. If I choose to go with either CWM or TWRP, how much of an issue is it to flash back to stock recovery? would it be done through ADB the same way the custom recovery was flashed in the first place?
As I understand.. the first thing I should do after unlocking the bootloader (already done) and flashing a custom recovery (not done yet) is to create a backup through the custom recovery. Does that back up the radios as well? If I decide to flash the all in one LTE zip and it doesn't work or what not.. will using that recovery flash back the old radios?
Now to the actual rooting..
so flashing super su is what actually does the root? How would I go about returning to complete stock if I ever need to? (stock recovery, remove root, lock bootloader)
When flashing a different ROM, how come I need to make a backup of my apps? what if I want to start completely fresh? Would I not be able to go to the playstore after flashing a custom rom and downloading everything I need? or there is not going to be a play store after flashing? (that's why GAPPS are needed?)
so I rooted and flashed the hybrid radio, works like charm!
I answered most of my own questions in the post above just by going through the process.
What happens if I decide to factory reset through settings? will CWM stay? will the root stay? will the lte fix stay?
Yes...yes...yes.....you really should take advantage of the countless guides people have written explaining all of your questions.
