Hi. I brought a cheap TF201 that wouldn't boot, thinking it would be an easy fix. It's working with stock ROM now, but I can't flash anything else to it. The story goes like this:
When I got the tablet, it would only boot into TWRP 2.6.something. Trying to boot normally would just bootloop. So I transferred some ROMs to it, KatKiss 6 and 5 and cyanogenmod 11, and tried installing. They all failed with somewhat different errors, like unable to mount /system or failed to create symlinks and none of them would boot. So I reformatted /system with EXT4. Some of the ROM files would still not install, but one did (can't remember which), however it would still just bootloop. cyanogenmod 9 would complain the device was a tf201t and and not a tf201. So I went for the stock JellyBean ROM. It failed to mount /system. I tried reformatting /system to ext3 and the ROM installed and worked! But it also tried to change the recovery back to stock, breaking it. So I flashed the latest TWRP blob for JellyBean with fastboot, and got recovery back. This recovery is (TWRP 2.6.3) is a bit different, and missing the option to change filesystem. I tried installing cyanogenmod again, but it broke /system again. As the new recovery didn't have the option to change filesystems, I used the terminal to mkfs.ext2 /dev/block/mmcblck0p1 (the recovery didn't have mkfs.ext3) and installed the stock ROM again. So, this is where I'm at now. Having a tablet that works using the stock JellyBean ROM on ext2, but not anything else.
What should I try from here?

Background:
Rooting and flashing roms since the HTC Hero, continued with the HTC Evo 4G, and currently on the GNexus. I am not a programmer, but very comfortable with several rooting methods and I understand the ins’ and out’s of backups, nightlys and bugs and glitches.
I bought an Asus Transformer Prime (Tf201) as soon as I could. I resisted the urge to root because its lightly skinned ICS Rom was really good. Once JB came out, I started getting antsy and started researching root methods.
I was on build version .28, and after a couple of failed root attempts Debugfs Root v1.8 worked.
I tried several roms, CM 10, Team EOS, AdroWook- and things were good, until….
Current State:
I think it was CM 10, things were just OK.. not great, and I missed some of the stock Asus apps which I liked and used often. I was previously on AndroWook, which was awesome because it had stock apps, plus many more customizations. So I Nandroid via TWRP as my recovery. And flashed CM 10. Didn’t like it so I flashed the nandroid backup of the Androwook ROM.
Now here is where things went bad. I didn’t factory reset wipe before flashing the nandroid. I did wipe cache and davlik.
Everything was fine. Until I noticed a few bugs, and I chalked it up to not fully wiping before the restore. So I tried to go back into recovery and wipe and re-flash the restore file. But no recovery found.
Nothing is left of a recovery file. And while loading up Titanium Backup it says I am not rooted.
I spend a lot of time trying to fix it. Trying to re-root via debugs, getting busy box, Super user, nothing works, I can’t get to recovery, I am not rooted anymore and none of the root methods work. I have a custom rom on, AndroWook, working fine, but I am stuck, no recovery no updates, no titanium backup, nothing!
Recap:
• Was unlocked, rooted, and on custom roms. TWRP was recovery image.
• Was on CM 10, didn’t like it, flashed back to ArndoWook via Nandroid backup restore
• Did not factory reset before flashing back to nandroid, but wiped cache and davlik
• Now the rom is no longer rooted, can’t use any of the root methods, always says SU not found
• I think it has something to do with superuser, at least that what every app that needs root can’t find.
• NO recovery image available,
Any Ideas? Thanks for the help
You should be able to flash a recovery from fastboot mode.
to get into fastboot mode, press and hold volume down while turning the prime on, when it says press up to enter recovery... dont.
wait for that to time out, you shouls then get a few icons on the screen. navigate to the icon that has a USB image and press volume up.
your tablet should now be in fastboot mode.
you will need the fastboot driver, android SDK and twrp image for the tf201 to continue, you will find the answers to these bits on the forum if you are missing any.
you can then flash the recovery with the following command:
fastboot -i 0x0B05 flash recovery recovery.img
(Replace the recovery.img name with the correct name of the img file)

Me too!
So I'm in the same trouble you are in only got there a little differently. For me without thinking I had accepted the Firmware update for the keyboard dock. After that installed my keyboard is bricked. The Tablet sees it and sucks from its battery, but none of the keys or track pad work. So I decided to do a complete full wipe of everything (Also on Androwook 1.3) and cleared out everything. It all looked like it went good, until I noticed no root. I tried to get back into recovery and cannot. Can't even get into Fastboot. Here is the details of what I'm looking at.
When I try to get into Recovery/Fastboot - Holding PWR and Volume Up will make the tablet buzz like its going to turn on but then never does. I will only see something on screen if I don't hold volume down and let it boot normally. If I try to reboot into Recovery from power menu, it goes to the dead Android screen (Android laying on his back with red exclamation).
So I tried to recover root and kept noticing that all the methods were giving 'access denied' or 'could not copy file' messages. Finally drilled this down to missing SU. When I ADB Shell in and try to SU it give me a 'SU: not found'. Unfortunately I don't have a backup of this anywhere and the only once I've been able to find is in the System/Xbin/ folder. However when I go to Xbin and SU it gives me the same 'SU: not found' message even though I see it in there.
Is there a way to download the SU and put it somewhere else to be able to get full access so I can then try the other steps of recovery?
Any help would be greatly appreciated, I'm going a little crazy here. Thanks in advance!
Hello Everybody,
my boss got me a Galaxy ACE S5830i in order to test some app development and I immediately managed to root it and install a custom ROM.
These were the steps I took
1- I flashed the update.zip I found around the web, for example here -> http://www.theandroidroot.com/root-install-cwm-recovery-samsung-galaxy-ace-s5830i/
2- I flashed CWM 5.0 and immediately, without rebooting, saw the new Recovery. So it really did install!
3- I updated to CWM 6
4- I flashed thunder kernel in order to make the CWM permanent -> http://forum.xda-developers.com/showthread.php?t=2335947
5- I rebooted the phone in recovery mode and got the CWM. Everything was fine up to now
6- I flashed a ROM (after wiping everything). Actually, several roms. I tried first with CGM, then with Aroma and Retribution Beta. http://forum.xda-developers.com/showthread.php?t=1806471 All of them managed to install but none of them works. What ALWAYS happens is that the ROM installs, then I reboot and the phone does not go past the Samsung Logo. Then, and here we come to the weirdest part, when I reboot in recovery mode in order to flash another rom... I get the stock recovery! No CWM, no customizations!
What's happening, in your opinion? I tried to flash a custom ROM with Odin as well, but being on Linux I had to use JOdin and could not manage to flash anything because (as it ALWAYS happens with JOdin) I was not able to load a suitable PIT file. No success with wine+odin as well.
Please, could somebody help me? I can't use my boss phone, and can't return it to him until I get a working ROM on it
Thank you in advance
P.S. When I get to the Recovery I see some rows to the bottom:
-- Appling Multi-CSC --
E:failed to mount /system (Invalid argument)
E:failed to mount /system (Indalid argument)
and (I know 'cause I tried) I can't mount or format the /system partition. Maybe it's related, maybe it's not...

Hello,
thank you for answering.
I can temporary get to CWM recovery for sure, but I don't know how to push the erase_image file (that I found) to the device. I'm only able to copy files on the SD, using another phone, and then flash them from CWM. Is there a way to make adb able to detect the device even when it's in recovery?
Thank you

Are the ROMs you tried based on CM7/9? Because if they are, you need to format your system partitions to EXT4. You can do that with the multi-formatter.
Also, you say that you have your stock recovery back. Check the ROM zips that you flashed for any boot.img. If there is, check which kernel and which version. Some older kernels still have stock recovery.
As even stock recovery cannot mount /system, clearly your system partitions are corrupt. Format with the multi-formatter and flash a CM7/9 based ROM or flash back stock firmware via Odin.
If you choose the multi-formatter, remember to flash a kernel afterwards. And if you prefer, one with a permanent CWM.

Hey guys,
I got a TF201 tablet.
I was trying to install the crombi-KK rom on it.
After several hours of trying and failing I found out that I had to install TWRP 2.8, but to do so, I needed to run the hairy bean boot loader.
When I figured that out, I shut down the device, and then nvflashed it back to the stock FW.
When the flash finished, the tabled was no longer booting (weird because I have never seen it failing after nvflashing the stock firmware).
After nvflashing it, the bootloader when back to ICS. I installed flashed TWRP using fastboot, when I started the recovery image I got a message asking for the password for data. After doing some research on that I figured that I needed to format the data partition for it to boot again.
Once that was done, the device boot OK to the stock ROM. I tried upgrading back to JB using the asus upgrade procedure and the tablet rebooted back to ICS.
I tried to install the stock JB firmware using twrp, it says it completes OK but when I reboot the tablet it goes back to ICS.
I then flashed several other recovery images, every time I start the tablet in recovery I get a message saying that it cannot mount the /cache partition and others.
If I try to flash any ROM using any recovery sometimes it says it worked but the tablet boots back to ICS, some other times and says it failed and goes back to ICS.
I used to have a BAT that helped me formatting the partitions and then to flash blobs one by one, but I deleted it because I thought I was never going to need it anymore.
I was wondering if what partitions does this tablet has (EX: recovery, boot, app, etc).
Is there any toolkit that formats the partitions and flashes then using stock JB images extracted from the blob files?

Hi there,
Tried to install Hyperdrive but unfortunately I have crazy lags and problems with it. It is almost impossible to move around on the phone with it. The biggest problem I have is that It wont boot into TWRP recovery anymore. I made a backup before but when I try to install it with the android system recovery it fails (E:footer is wrong and E: signature verification failed)
I tried to flash Hyperdrive from recovery again (didn't work); I tried to wipe cache and format (didn't work)
Now I tried to flash a new Rom but apparently you cannot flash with the android recovery environment(I am also getting the two E: errors)?
Would like to get the phone back. Hope someone can help.
Do you remember the system baseband? This is critical. If it was MDK, then you could have used safestrap. If not, then you should have used safestrap, not MDK.
The A.R.E won't work, you need Odin + the tar file..
Hey,
So this is my first foray into this sort of thing. I have some computer background but I haven't really gotten into this sort of stuff.
I have an Asus Eepad Transformer T101. I was requested to load Android 6.0 on it.
I followed this thread:
http://forum.xda-developers.com/eee-...t/rom-t3318496
I had to learn some things my way. User Debugging was on but I couldn't flash recovery. I ended up finally flashing recovery (I forget what step I had to do to use Clockwork Mod Recovery).
Once I was into CWM I had E:\Cannot Mount \sdcard\.
I then found out I had to use a micro SDcard, fine.
I couldn't load anything, and no solutions were working for getting SDcards to work.
I found a thread through google that said to use SD Formatter, to no avail.
Then I found this:
http://www.transformerforums.com/for...-firmware.html
I have the files and. It was a batch file that loaded ADB then I could flash recovery. I attempted to flash recovery and I got to rogue XM recovery 1.5.0 (CWM - based recovery v5.0.2.8)
I used Nandroid Backup (Note, still could not mount SDcards)to do a backup of everything to the internal storage. I then did a wipe of all user data.
I have a folder called Marshmellow with Katkiss-6.0_025.zip, open_gapps-arm-6.0-pico-20160219.zip and BETA-SuperSU-v2.52.zip.
I attempted to install the KatKiss one, and it failed saying:
"Installing Update...
set_metadata_recursive: some changes failed
E:Error in /sdcard/marshmellow/katkiss-6.0_025.zip
(Status 7)
Installation aborted."
So here's where I'm pretty sure I screwed up.
I loaded the Gapps and SuperSU.
Tried marshmellow again, and no luck.
Now the device boots to the eepad transformer screen, lasts a few seconds (usually no more than 10) and then reboots.
I've tried
http://forum.xda-developers.com/show....php?t=1688012
and
http://justanotherdave.ca/?p=351
The latter simply doesn't work. And I don't think I can get into ABX mode for the former.
Are there any resources on how to "unbrick" the device that may still work. Right now it just keeps rebooting at the nvidia eepad screen. I can get into recovery still.
