I have been unable to restore any of my nandroid backups. They are all listed, but nothing happens when I select one. I tried doing it first with ROM Manager and then tried the Vol Down - Power button approach. All I get is a blank screen. Does anyone have any suggestions? I have no trouble installing ROMs from the SD card.
u should have a custom recovery installed in the first place.. do this..
go to recovery by holding down home+vol down+power..
use the stock nandroid backup..
Did you say to hold down Home+Vol Down+Power? I haven't heard of using the Home button before.
yes in some buttons its home button+power+vol down
try it
Try updating CWM in ROM Manager. The latest version is 3.0.1.0
I tried flashing ClockworkMod using ROM manager, and the first time I tried it I got ClockworkMod 2.5. I have tried several more times, but now it immediately responds with a message saying it was successfully downloaded. It couldn't have downloaded anything that fast! Also, I have made several nandroid backups but am unable to restore them and am wondering if I need to have S-OFF for it to work. If so, how well does the Unlockr unrevoked-forever.zip program work? I can flash it from the SD card since I have successfully flashed the Froyo USCC ROM. That much does work.
They should be there.

I rooted my TF101 model B80 using RazorClaw (nvflash is a no-go for this model). Installed CWM, all was well. I tried to install Prime ROM from CWM, and was unimpressed; tried to restore my Nandroid backup of original rooted OS. Now, Transformer will not boot into any recovery (neither CWM or original green android), and screen comes up garbled. Is there any way I can restore my original stock by merely putting a particular image on my external sd card?
Any other suggestions welcome, I just can't get to a screen (recovery or otherwise) where there is any readable text I can respond to. Nor can I turn the device off. It will continue to reboot in this fashion. When I get home today I'll be able to start from a dead battery.
Thanks
Did you wipe before restore?

Yes, I did a full wipe including dalvik cache before all restores. At this point, though, my primary concern is just finding a path back to usability!

I had the same situation..I used the unbrick method:
http://forum.xda-developers.com/showthread.php?t=1123429
then you could try restore a backup ..
To turn off the device press the power button for 10-15 seconds..

I can try this when I get home today.... I'm just concerned because the method involves nvflash .... which I thought didn't work from the newer TF models (I have a model B80). I needed to wait for the RazorClaw exploit because previous attempts at using nvflash failed....
Then NVFlash will fail still...

Being you can't get back into CWM not sure how you'll flash the stock kernel.
HAve you tried Holding Vol Down button plus Power button till you get prompt to enter recovery at which time immediately push Vol up button withion 5 sec.

OK .... my bad.... I guess I wasn't pressing the buttons in the right sequence/duration. I CAN get to CWM!
So, once again, I try to restore the Nandroid backup and after rebooting, end up with the screen situation as in the reference you provided.
So, I am assuming my Nandroid backup is not restoring the kernel that it needs. I was running a recent OTA update; I believe the version was 8.6.5.19.
Where can I get the appropriate kernel to install from CWM? Does it matter in what order I install the kernel and the Nandroid backup?

Same issue, no recovery though
Hi,
I have the same issue as the original poster, B80 serial, RazorClaw root. However, when I boot to recovery I get the green android with yellow triangle and exclamation mark.
I need to restore a recovery on my device as I may need to unroot to send to Asus. I have an even deeper problem of having to have the device connected to power for it to turn on after shut down.
However my main question is for that serial number and root method, what is the best way to flash a recovery on my device (stock or CWM) if I can not get into recovery to begin with?
P.S. RecoveryInstaller will not work, after installing the apk, I click the flash recovery button, the system holds for a bit, then nothing happens.
I will continue to search the forms for some answers, any insights or direction will be appreciated.
I can get into apx mode.
Thank you community!
I think you can flash the recovery via the staging partition. Search around the TF section, it's in here somewhere. Although, I wonder why the 1 click recovery didn't work?

Everything I see in the forms requires one of several conditions which my TF doesn't currently meet.
1. Recovery. I can not go into any recovery, thus I can not perform any flashing of any other rom or recovery.
2. B70 or later. Because of the security in the boot for these new serials, I can not use the NVFlash tools to un-brick / flash.
I am already rooted, however I do not know the reason for lack of recovery on this device. I unfortunately bought it yesterday from Craigslist, so not sure what this guy did before I got it.
I searched for flashing recovery staging partition and did not find anything immediately relevant. Please advice is there is a different wording I should use in my search as I am now getting an immense download on all of this trying to figure out what to do. I am also fairly new to Android devices having 1 other phone that is rooted.
Thank you for all the support and quick response! wonderful community here.
Try searching for posts with /dev/block/mmcblk0p4
This is particularly dangerous because you don't have access to nvflash. If you get bootloops, it is bricked. You have to be sure that whatever you flash will be 100% compatible with what you have now.
Also, when you try to boot into recovery, what does the text at the top say? There should be a version number in there somewhere.

Thank you gee one. I have since been able to install clockworkmod. My issue with the power not turning on if not plugged in still persists, I have started a separate thread.
I found your post on the staging partition here:
http://forum.xda-developers.com/showthread.php?t=1309949&highlight=power
Do you recommend this for the issue still persisting?
If so, considering I am on 8.6.5.19 will I have to use the blob from that? It is not on Asus website as I got it from the firmware update option in the settings before loading up my new ROM.
Do you recommend this step as the only resolution or is there another way?
Ok let me get this straight:
You have clockworkmod installed. Can you boot into it and do the buttons work?
Are you getting a garbled screen when you boot into the rom? Or are you just trying to unroot?
The tricky part is to avoid the bootloops of death.

Honestly what i would do if i were you, assuming i understood correctly that you can get into clockworkmod, just reflash the prime rom you didnt like(after wiping everything, including cache and dalvik), and if it boots and everythings okay, at least you know nothings really wrong with ur tablet. As for the plug in situation, make sure your battery isnt simply dead. As far as i know, it wont charge from recovery, so if uve been stuck without a booting rom for a while, it being dead could definitely be possible. Once you are in a working rom and you sorted out the charging issue, then you should worry about getting back to stock.
Thank you camaros,
I am able to load stock ROM successfully.
Battery is not dead as it is fully charged, and will run un tethered after powerup. I will test resetting it although I doubt that is causing it.
What i would like to determine is, is this related to a hardware or software issue?
Also, is there a way to restore stock recovery from CWM?
I would like to ask what are the negative effects of having a broken recovery, I flashed my stock recovery with Generic RK30 CWM and now it is not working, i also tried flasing back my recovery.img but it does not work, it flashes but still the recovery is not accessible thru adb reboot recovery or button combination.
thank you :good:
What is your phones name?
On most phones , recovery lets you make a factory reset, but it is essential if your device can't boot.

Backup and restore is one of the main features of a custom recovery. All recoverys have this feature.
I am using philz touch
You can search thread named script recovery installer it is the easiest method for flashing a custom recovery

And then again after sometime when i opened the recovery
What i saw is my old recovery was there

hey guys!
i am having this problem where my phone wont boot. When i try to boot the phone, i am met with a totally black screen and the the little light at the top of the phone is just white. i was trying to do a recovery with twrp with a backup i had made. When it was done i just couldn't boot anymore. I can still boot into recovery mode and to the bootloader.
if anyone can help me with my issue then i would be happy if you could respond to the thread a possible solution, or if you want, you can msg me on discord (TobiS137#2131)
Thanks in advance!
Use msm download tool from the forum. It will format and reset ur phone. Also read up on what you can and can't do with TWRP at this stage ...

Were you trying to downgrade from a Pie installation back to Oreo? That can be a problem. Lots of info on that here.
If you weren't trying to do that, try changing the active slot in TWRP. It may or may not work, but it's quick and easy, so it's worth a try. You could also reinstall the ROM you were restoring on top of the Nandroid backup. That might correct whatever is off about your restore. These aren't sure solutions, but they're easy and don't take long. If something like this works out, at least you'll have your apps and data from the backup preserved and won't have to start over again.

Get back into recovery and flash the ROM zip again, TWRP, reboot recovery, magisk and whatever else you flash as part of your preferred mods. The data can stay in tact regardless, unless you go to another type of ROM.
