Hi.
While trying to upgrade my tablet to a later version of Android, something borked the bootloader. The tablet boots fine to a bare ICS (no gapps, but ROM MANAGER installed, though it does nothing but hang), but trying to boot into recovery mode hangs it (black screen with android robot, OEM info).
I can install apks to the tablet. I have installed ADB on my PC and it sees my tablet.
Where do I go from here ?
I have no clue
- what exact file(s) I need (my tablet is an Ainol novo8 advanced)
- where I need to put them
- what the commands are to do that
- it should be rooted (the superuser app aloows me to grant su privileges to apps)
Any help that can bring my tablet back to life would be very welcome.

If you can still use ADB your tablets bootloader is likely not messed up, it sounds like you booted the tablet into fastboot mode not recovery. To get into recovery you can enter it by holding a key combination the most common combination is holding volume up plus the power button at the same time. If that doesn't work from ADB you should be able to get into recovery by running the command:
Code:
adb reboot recovery
Also ROM manger doesn't always work right with every device so I would recommend just uninstalling ROM Manager for now. If it is booting fine into bare ICS then your tablet should be ok, if your looking for Google Apps for ICS they can be found here http://cmw.22aaf3.com/gapps/gapps-ics-20120317-signed.zip. Let me know if you still have questions .

Thanks a lot for your answer.
I'm sorry I didn't describe the issue well: I can no longer access the recovery mode.
I used to get to it by cold-booting the tablet holding Vol+ and Power. I used that to install ICS, gaps, powertools and 3D tools as described in http://forum.xda-developers.com/showthread.php?p=36059461#post36059461. The first package (recovery CWM) failed to installed because it was unsigned), the others installed, but in the end it seems I only got ICS: I have no gapps.
Now doing Vol+ and Power only gets me to the boot screen (a green android with OEM info, on a black background). Your "adb reboot recovery" does the same. I can only exit that screen by a hard reset.
During a normal boot, that screen flashes by for a couple of thesconds, then another, then the ICS colorful boot animation.
I have no clue how the recovery boot process works. I'm guessing it's reading a file of the internal Flash, and that file or dependencies got corrupted or partly overwritten by one of the packages I installed ? I'm not even sure if CWM recovery replaces the default recovery mode, or if it chains right after it ? I do have a supposedly-working CWM recovery .zip from the authors of the CM10 hack, as well as the "original" files listed here: http://forum.xda-developers.com/showpost.php?p=31089682&postcount=286 (official images from an out-of-the-box, unhacked tablet).
PS: the recovery mode I used to have was very rustic, only taking "update.zip" as an input, so when I did the update I had to go back and forth renaming the first package to "update.zip", applying it, renaming it "update1.zip, then on the the second package, etc, etc... It said Android System Recovery (3e), so maybe 3e was the version.
last but not least, if I could at least get the gapps onto the tablet, even w/o fixing the recovery mode, it would be very useful. I can install apks, or follow instructions to do it via adb ?

The recovery you are referring to is to the standard Android 3e recovery it is included in every version of Android, and will always be like that unless you install a custom recovery such as CWMR and or TWRP. As a general rule you should never install a custom ROM without having a custom recovery image installed first, essentially all the stock 3e recovery is good for is installing OTA updates and preforming a basic factory reset of your phone. You should try and fix your recovery before going any-further, you can sign the un-signed zip by using this tool. Overall, I would focus on trying to fix the recovery to prevent any further damage to your tablet and so that way you have a simple way to recover from anything that might go wrong when flashing ROMs, mods, and other zip files.
issue with the uImage linked
The uImage linked on the download pages for the CM10 and CM9 version ends in ".*"
I have no clue what the normal extension should be; replacing that *.zip doesn't work. Is the file bad, or am I just too clueless about what to do with it ?
Ok so the question is:
1- which "recovery mode" file should I install on my tablet, especially since the mod author's ones seem flaky
2- how do I do that via ADB since my tablet no longer seems to have a working "recovery mode".
I'm sorry to hassle you with those questions... I've looked around, I can't find info nor files I'm confident about ?

I am absolutely new to this Android ROM installs on the phones. Though I decided to install this ROM I absolutely didn’t’ have any idea how to proceed. As a beginner I started doing the following in order.
Download and Keep the CM7 ROM
1. Downloaded Ba2F.zip to my laptop
2. Downloaded and Installed the Motorola USB drivers MotoHelper_2.0.53_Driver_5.2.0.EXE
3. Connect the Atrix and set the USB option on the phone to “USB Mass Storage”
4. Copy both BaTF.zip as well as the Extracted one to Phone internal storage as well as the Ext-SDcard on the phone
Download ROM Manager and Titanium Backup
1. Downloaded both from Android Market (ROM Manager Pro and Titanium Backup Free Version)
2. Both Apps won’t open because I had not ROOTED the phone
Root the Phone
1. I used “Pete's Motorola Root Tools.EXE” file to ROOT the phone
2. Followed step by step as mentioned here http://www.androidauthority.com/how-to-root-motorola-atrix-4g-35233/
Flash ClockworkMod Recovery
1. I used ROM Manager to do this as when you try to do anything in ROM manager it prompts to do this. The version of this is 5.0.2.0 ( I am not sure what is this for why we have to do this)
Unlocking the Bootloader
1. What I learned is, to unlock the bootloader, we have to first flash the phone with the SBF file
a. Installed RSDLite5.3.1.msi
b. Loaded the file 4547-fix-try2.sbf (Downloaded from http://forum.xda-developers.com/showthread.php?t=1136261)
c. Boot the phone with Power+volume UPPER key pressed till "Starting RSD protocol support" comes up
d. Connect to the Laptop and Hit Start button in RSD Lite Program
e. It Did Throw an error saying “FAIL” after showing the following message
i. Failed to boot: error 0x1000'( not word for word). There will also be a list of boot options like Fastboot, RSD, Recovery, etc. And it says Starting Fastboot Protocol
2. Then comes unlocking the phone
a. Though I had the previous error message, it still had the Fastboot Protocol loaded
b. I went to the FASTBOOT folder in command prompt of my laptop executed the following to unlock the phone which worked perfectly as I see the “Unlock” on the left hand corner when phone boots
c. fastboot oem unlock (it gave me the code) then I used the code to unlock
d. fastboot oem unlock #######
e. fastboot reboot
3. Installing the recovery IMG
a. I had downloaded the Recovery IMG file (recovery-atrix5.img) from http://forum.xda-developers.com/showthread.php?t=1204500
b. Booted the phone into Fastboot mode (turn off phone, hold power and volume down key until 'fastboot' appears then use volume up to select so it says 'starting fastboot protocol support').
c. From the CMD promnt and FASTBOOT directory I used fastboot erase recovery
d. Then I executed fastboot flash recovery recovery-atrix5.img (Note: I didn’t rename the file to recovery as suggested by some people)
e. Then gave fastboot reboot to restart.
4. Booting into Recovery mode (This is where I have the problem)
a. The phone is not booting into recovery it’s not going past the Android and yellow Triangle screen
b. I re-flashed the phone same SBF file (this time it was a success showed in the RSD Lite Program), re-installed the same IMG file after renaming to recovery.img
c. Also tried with a different IMG from the same link (recovery-blue-atrix5.img) but no luck
d. Also deleted the file install-recovery.sh from ./etc/ folder (bought the app root manager to delete the file) and then push the recovery.img, no luck
e. Some people said to TAP the bottom right corner while on that screen, did that but nothing is happening
f. Then I saw a note to press both the Volume Keys at the same time, this works but in this mode the cursor (I mean the selection) on the phone doesn’t go to the First TWO (i and iii) shown below, it allows me to select any of the last FOUR (v, vi, vii, viii).
i. Android System Recovery <3e>
ii. <EMPTY LINE >
iii. Android System Recovery utility
iv. <EMPTY LINE >
v. Reboot System now
vi. Apply update from sdcard
vii. Wipe data/factory reset
viii. Wipe cache partition
g. Using the above option I did factory reset but sill no results.
5. Current condition of the phone
a. It boots in unlock mode and I can do all the daily tasks. But I want to install the CM7 ROM that’s my requirement
PLEASE HELP HELP HELP
First of all, I applaud your effort in giving the a very comprehensive description of your issue.
Second, it seems you are having issues with installing a custom recovery because the recovery you're describing is still the stock recovery. I'll look around and see if I can find something that might help.

Have you tried re-installing the CWM from RomManager through RomManager? And then boot into recovery from within the app?
---------- Post added at 11:40 AM ---------- Previous post was at 11:31 AM ----------
EDIT: This might seem trivial, but is "USB Debugging" turned on?
You are the Man, I just flashed the same CWM 5.0.2.0 and i am in the recovery mode. This gave me an error when i did last time hence i didn't try again.
Thanks a bunch
Glad I can help, also, I think it's recommended to use the RomManager recovery for CM7 so good thing it worked.

Oops.. started again, Can i use the recovery-atrix5.img and ROM manager flash it? if yes, then how?
I copy this file (after renaming to recovery.img) to both internal storage and SD card then what option should i choose in ROM Manager?
If you downloaded the CWM zip file for the romracer recovery and as long as RomManager's recovery is working then, yes, you can.

See post#2 from romracer's thread. Read the Miscellaneous part. Probably need to get rid of, or backup, install-recovery.sh.
He has mentioned he already did that. In his OP, under the steps he took look at "Booting into Recovery Mode" - 4.d, he says he removed it.
Maybe he's not doing it in the right order? Do you happen to know which should be done first as far as installing recovery and removing said file?

Woops, I should have read more carefully. It's best to remove the file first and then flash the recovery.img, or else the script will install the stock recovery on boot. That would make stock recovery the current one on the phone at the time of the script getting deleted.
I would double check and make sure /system/etc does not have install-recovery.sh. If it is not there, then proceed to the fastboot steps and reflash the recovery.img again. It should stick this time.
@Ghost, yes i deleted the file multiple times however i didn't find the /system/etc folder on the Internal Storage. however I found the install-recovery.sh file under /etc folder. The thing i observed that whether i flash it with a new CWM or not if i reboot the phone then it was created by itself.
@Live4nyy, Thanks for your suggestion, I could able to install CM7 now and it looks awesome good so far, but looks like i need to install Google Apps separately to access the APP market, am I right?
The only thing that happens to me is, it allowed me to go to Recovery only ONCE after i Flashed it thru ROM Manager, if i exit out of recovery without doing anything then next time tried to go to Recovery, it will struck at the same old Android screen and i had to flash it again. But Many thanks for suggesting to flash it thru ROM Manager.
Now with CM7, under ROM Manager (I guess this comes default with CM7) I see there is no version listed under "Flash Clockworkmod Recovery" and it says i must have to install it in-order to Flash and restore ROMs, do i need to do that? I can go to Recovery mode after reboot without any issues. Please Advise.

I just checked out my girlfriend's stock, locked, unrooted Atrix and she actually has install-recovery.sh in both /etc and /system/etc. Her file manager does not alphabetize anything in either folder, so I almost overlooked the second one.
If you're already on CM7, then you probably won't need to worry anymore. They have an entirely different set of start up scripts in that folder. Welcome to the community!
At this point I do not know enough to help you any further with this issue. All I knew about is the file that needs to be removed that @ghost_og has mentioned. But if you can flash it from RomManager and access CWM from there as well then I guess that's a good enough workaround for now.
Does anyone else have any idea why the stock recovery cannot be removed?

I am good to go now, everything seems to be functioning well after flashing CM7 ROM, no more recovery issues, and the Stock recovery is gone now.
Appreciate for all the info you guys provided, it helped a lot. Have a great day and Merry Christmas.

Hey guys,
I have a bit of a head scratcher. I am currently trying to flash my new Sanei n10 tablet with CM10 and it is proving much more difficult than I first imagined.
My main problem seems to be that the device just does not want to boot in CWM. I have installed the latest version of CWM (found here) via the Terminal Emulator but it doesn't boot into CWM Recovery, but rather just boots normally. I have also tried using the hard keys to boot into it but all that does is boot me into the default android system recovery (3e) which is useless as it will only update from verified roms.
The device is rooted and I have ROM Manager installed. I have given Terminal Emulator superuser permissions... It just doesn't seem to want to boot into CWM Recovery. I have tried using both ROM Manager as well as NOVO7 Tools to boot into it but I get the same results (device just reboots normally)
I think that it might be something to do with the stock ICS 4.0.4 that came with the device.that is causing me so much hastle, but I was hoping someone out there might have experienced a similar issue or can offer some insight to where I am going wrong.
Thanks in advance!

1. Download the latest ClockWorkMod for Allwinner A10 tablets from here:
http://forum.xda-developers.com/show....php?t=1802268
2. Put all three files in the ZIP inside the root of a MicroSD card and insert it in the tablet
3. Check from the Terminal app inside the tablet to see if the MicroSD card is mounted in /sdcard (just type "ls /sdcard").
4. If the "ls" command doesn't show anything (that's what happened in my case), then you must modify the "install-recovery.sh" file and replace all instances of "/sdcard" with "/mnt/extsd".
5. With the proper "install-recovery.sh" file, run the commands specified in the above xda link (in my case the card is in "/mnt/extsd" instead of "/mnt/sdcard" as the original example shows):
su
cd /mnt/extsd
sh install-recovery.sh
sh reboot-recovery.sh
6. The tablet will then reboot to CWM recovery. Then follow the regular steps to install Cyanogenmod (wipe plus install ROM + GApps + Compatibility). This time the Recovery menu won't care about the files being unsigned and will install them right away!
So, I've stupidly let my son try and flash a custom rom on his generic chinese tablet (Cambridge Sciences StarPAD 9 SE) and he found a few very similar spec tablet roms on the internet which said they require TWRP to be installed before flashing. So he's installed that, rebooted into recovery but the TWRP doesn't fit the screen in terms of resolution size. Now, that's not the main problem. The main problem is that the touch screen doesn't work at all within TWRP so I can't select any of the options. Whenever I power off the device and power it back up, it reboots to TWRP and doesn't boot to the main ROM. He said that it did originally reboot to the ROM whenever he first installed the TWRP because he said that it was the only way of getting to the recovery. So I thought that I could just use ADB and just force a reboot from there but off course, there is no ADB device driver to be found on the internet.. well not that I can find anyway.
I'll attach a photo for you guys and hopefully someone can help me with this as I've spent the best part of 2 days trying to figure out a fix but am now stuck.
I'm now able to access the device by adb however I don't know what to do from there.
Any help?
Does anyone have any firmware for this device? I can't find anything on the internet at all. If I could get a firmware img then the device will be fixed.
The build number from the firmware is: fiber_evb-eng 4.1.1 master 20130530
the command is "adb reboot" AFAIK
Did he take a nandroid backup before flashing? It looks like a version of twrp that is not compatible with the tablet was installed. Not every device supports touch screen recovery mode. Can you use the volume rocker to navigate?
I can almost guarantee you won't find the firmware for a Chinese tablet. I've just been trying to help someone in a similar situation but the best we could manage was a ROM that had lots of glitches.
Edit how did he flash TWRP if it was incorrectly flashed ie: fastboot flash boot recovery.img instead of fastboot flash recovery recovery.img then that may produce a device that would boot straight into TWRP. I've heard of that happening on a nexus 7

Hi,
I have a UK Nabi2 which I used Nabilab2 to install TWRP+root+google apps a while back. I needed to do the new two part OTA update, for warranty reasons, so went to install my original backup, but could not find it. I used Nabilab2full and did the stock install, which removed root and returned the device back to stock. (This also changed my nabi to a US version with no serial, FW 2.1.29. which I later found out). & at that point I still had TWRP.
I did the first two of three OTA updates (which worked), the third update crashed during install. I retried the OTA twice more but each time it crashed. The device lost TWRP after this.
Upon entering recovery with ON/Vol+ I now get <3e> recovery. Running the root.zip file from sd card fails (I assume as I am not in the correct mode or have a bad file?). The OTA updates I grabbed from the nabi wiki page (and the thread, see below) also fail.
My device does not show in fastboot. Adb sees it but when using the command, C:\adb reboot recovery, the Nabi reboots and goes to the dead android (pushing -/+ to get into) <3e> recovery, and adb at that point no longer sees the device. The nabi also disconnects once adb shell is executed. I can intsall .apk files via adb command but I still need root access to run TWRP backup manager. I can run the root.zip file via an apk installer, but when running SU it gives a message 'There is no superuser binary installed, and superSU cannot install it. This is a problem!' ...Is there another way can I install root and/or the recovery.img to the Nabi2?
(I have been following the thread here, http://forum.xda-developers.com/showthread.php?t=2041224&page=10, as well as several hours worth of reading various adb, <3e> recovery, lost root etc q&a's in other places but cannot find an answer, or it's assumed that the adb reboot recovery command is working, which mine appears not to be).
Any help or pointers in the right direction would be very appreciated.

Hi,
I have quite a similar issue with this. I flashed custom recovery and forced gapps, but now cannot flash original recovery to perform OTA update. Cannot boot into custom recovery at all.
Done a system restore so now i have lost the gapps that were pushed and cant get into recovery to flash them again :crying:
Thank you for the reply mate, sorry to hear you are in the same situation more or less.
Further reading over at Stack overflow help forums seems to lead me to believe the tablet is bricked. Loss of su/root privileges means no r/w access via adb to put the required files where they need to be, or install or TRWP.
I'm not giving up on this... well not yet. I have a ton of other work related things going on right now that I need to clear down so I can look into this a bit more seriously. I'm away till the 17th April but will check in here when I can. And, if I find a solution I will post it here.

You need to select fastboot protocol in the menu after booting with pwr/vol buttons. Then install fastboot driver, then install TWRP. From that point the thread you linked will work.

Doesn't matter if you flash the original recovery, you need to flash the original system. TWRP can do the OTA but it will fail because there are a couple of system files that were changed that fail SHA-1 checks. Don't know what version you are on or if it's a UK or US or Disney/Nick version.
aicjofs,
Thanks for the pointers! ...its most appreciated.
After checking, I do see the nabi in device manager when its in fastboot mode, but its not installed properly (it says 'Android device' but has a 'fastboot' icon with an exclamation mark under it) which would be the root of my issue I would have thought. I was certain the fastboot drivers were installed too, obviously I was wrong.
*EDIT*
Success!
I had java disabled. I also had issues with device manager switching from 'Android device' to 'Unknown device' intermittently.
I started fresh by uninstalling everything nabi/sdk/adb related. Re-installed java, sdk and adb drivers, in that order, which resulted in no conflicts or driver issues! Then when I put the nabi into 'fastboot protocol' the second menu then appeared (which it was not doing previously). I flashed the 2.3.3.0 TWRP recovery image.
Now I have some more reading to do about what image I need to put back onto the nabi.
Thank you.
*EDIT*
Thanks again.

Somewhere in that post you linked I put a pretty good procedure for getting a UK Nabi to the latest OS, hopefully you will be up and running in no time.
I'm there, finally. Using the link to the three part install you posted. http://forum.xda-developers.com/showthread.php?t=2041224&page=10 post #98
I'm now @ 2.2.2 (I think), 4.1jb, with 2.6.3.0 twrp recovery. First thing I did was make a full backup (once it was all working 100%).
I had a minor issue with SU trying to install repeatedly once I put the 2.2+ stock image (+modded ota), which sent the nabi back to <3e> recovery. But I just flashed it back to 2.6.3.0 with fastboot.
Many thanks ;0)

Hi Smirnofred, I have similiar issues to you, and i'm wondering of you can help. The 2.2 file from dropbox is no longer available, have you still got it? and would you kindly upload it somewhere for me if you have time. It would be much appreciated. :good:

A while back, Amazon automatically pushed an update to my kid's Fire HD 6. Since then, the device will boot up and then it just freezes. The screen stays on the device is unresponsive. I am able to get in to recovery on the device, and that all seems to work fine, but booting in to Android is useless because it just locks and you cannot do anything with it.
I have been trying to go through this forum to see what my options are for sideloading another firmware or TWRP or anything like that.. and the posts here are not entirely helpful (for me at least). I'm used to going in to recovery and flashing some zip files to install TWRP, Cyanogenmod or GAPPS or anything like that... but the instructions I see for installing TWRP and the like do not seem to be the traditional methods. From what I think I am seeing, to install TWRP you need shell access to the tablet and then you can use dd to write TWRP to the correct storage space.
What are my options for doing things through recovery with adb? Or can I load an old firmware and then go from there? Any help is appreciated - would really love to get CM12 on this thing in the end if I could.

Your understanding of TWRP is right. Basically, we dd the twrp image with OS 4.5.3 bootloaders (the only bootloaders that will boot unsigned recovery) and then before leaving TWRP flash back (almost) current bootloaders and recovery.
You should be able to adb-sideload the OS 5.1.2 update to fix the freeze. Was device rooted before it updated? Do you know what OS it was on? If you have adb access while device is frozen, run these commands for current OS info:
adb shell getprop ro.build.version.fireos
adb shell getprop ro.build.version.number
No CM12 available. Mostly-working CM11 is here: http://forum.xda-developers.com/fire-hd/orig-development/rom-cm-11-kindle-hd6-t3270138
BTW, I assume you tried wiping cache and/or factory reset in recovery. If not, I'd do that first.
