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 ?
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!

here
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!
I rooted my Nook using the method here. I then downloaded Goo Manager though the app store and installed TWRP recovery. If I choose "reboot recovery" in Goo Manager, it will grant SU access and reboot, however it will not boot in to TWRP. it will just reboot the Nook normally. Then I powered down normally and now my Nook won't boot at all! It just shows the splash screen and shuts off or bootloops if i plug it in. What's up?
Edit: I tried doing the root method over again to unbrick it. I could boot in to recovery but the tablet still won't boot after I flash.
Unfortunately I can't help you. Just give my view that whenever I have tried TWRP there has been issues. EIther "not just doing the job" which is annoying but not much more. But also getting stuck in bootloop. When that happened to me I stumbled on the repart.im recover image that put my Tablet back to "out of the box" condition. I ran it and after that I have used CWM without issues.
Hopefully someone will come along with a better answer to you.

How did you flash CWM? I can't find any flashable files anywhere. Did you do it through Rom Manager or something like that or did you download a file and flash it through a bootable SD recovery?
Back when I origianlly did it I did it like I outline in this post (under C): http://forum.xda-developers.com/showthread.php?t=2081981
Nowadays I do it differently though, but that process should still work.
GooManager does not flash the right recovery image for some root methods. The Nook Tablet one has acclaim in the name, and when I rooted mine, I realized it tried to flash a build for blaze. I just booted from a CWM SD to install my ROMs, and then flashed TWRP to internal using fastboot.

Fastboot is a tool in the Android SDK that can do a lot, including flashing a recovery.
Steps to use
Make a Ubuntu 13.04 virtual machine
Open Terminal
Put in : "sudo apt-get install android-tools-fastboot"
Install CyanoBoot if not already
When booting Press n in cyanoboot
Choose start fastboot using buttons
Plug into computer and hook up to VM
Download TWRP internal 2.4.3.0 from iamafanof.wordpress.com
Open terminal
Type cd Downloads
Type ls
Look for a file that starts with twrp
Type fastboot flash recovery then type the file name of the twrp file
Done

Guys, KITKAT is out for HP 7 Plus. I had successfully rooted the tablet on JB with no bootlooping issues but lost root when updated to Kitkat. Plz update your tablets and let us all work together in developing Custom ROMs and Recoveries.

Kitkat is available but it's flawed. Received "update -1" and left in recover mode until I rolled back.:silly:

No, it is not flawed. When you flash the zip the first time in recovery, it flashes your bootloader and recovery. Reboots into recovery again showing received update-1. Then choose the zip again. You have to do this 3 or 4 times. Keep on choosing the revovery zip again until it says completed.
Has everyone given up?
Hi guys,
anyone know how to root this phone?
root on Cubot Cheetah 2
https://forum.xda-developers.com/ge...bot-cheetah2-information-reviews-5-5-t3509666
I flashed TWRP, attachted as rar file. I did it like this:
http://forum.xda-developers.com/android/general/guide-clones-t3421539
Did you know that devices has build in recovery menu?!
It can only backup some user data for you
You can get into by pressing POWER and Volume+ for a few sec. while turned of tile boot.
Hold Volume + and press Power again.
***Do not press Volume down, it is "enter" in first recovery screen you maybe start fastboot or normal
***Volume + is for navigate in first recovery screen
Do not flash other super user as in thread... i did and had a heavy bootloop (;
hello
i cooked my 1st rom for a Cubot like this https://forum.xda-developers.com/showthread.php?t=1801690.
Then i flashed it with the recovery. As installation stoped i got a message: "no os installed do you realy like to reboot?!"
So i cancel process to restore systemfiles which i backed up befor. *
But now all system app are gone and recover them with Titanium backup doesn´t work well. I also got those files from stock image and maybe most by another backup by root explorer. What to do right now?
Try to install my rom again? Via fastboot? Or flashing a clean stockrom i don´t know.
I´m uploading Cheetah 2 rom i cooked since hours, it is ~2gb
Maybe someone can look into it
My pc is to slow to run a emulator to test it. That´s why i try flashing befor posting download link dang

Are you in develop mode, enable debugging or connected as android bridge?
I flashed today TWRP to another Cheetah 2! But this super user installation blow my mind and device!!! Installed chainfire (2.52) as in linked thread made my phone hang on cubot bootlogo. Then i downloaded SR2-SuperSU-v2.79-SR2-20170103215521.zip and i pass the boot but now all system apps are gone again! Recovered it with my TWRP backup.
Thinking about retry 2.72 SuperSu which maybe was reason of bootloop on 1st cubot rooting :fingers-crossed:
Keep in mind to backup your whole system if you enter TWRP 1st time, befor installing SuperSu. Suggesting befor install TWRP make backup with stock recovery!
Maybe a video i made on that 2nd rooting procedure is helpful to you?

Do a websearch: "unlock bootloader adb" example
It is basicly same step as in ultimate MT6753 thread url = see me 1st reply
You just need fastboot.exe and your Cheetah running as adb device to install TWRP.
Make sure you got it installed Cheetah via ADB driver not as MTP device or else!
TWRP is same on cheetah 1 & 2 not 100% sure, maybe ask megathebest .
Alternative method:
adb.exe to unlock and
Sp flashtool with vCOM-driver installed

Another method to install TWRP is via update.zip but if you have to unlock oem via adb (minimal adb fastboot.exe) why manuel flash it.
How:
Rename twrp.zip to XXX-stock-rom name-XXX.zip place it at you internal memory boot into fastboot by power and volume button.
Ya, there are loads of tutorial on the internet about TWRP 3.1.1 For Cheetah 2 which means root is possible for the device running the latest Android OS.
Here is a guide which has shared the latest TWRP 3.1.1 with rooting guide

i had the same problem but was very easy coming out. just connect the otg cable to your phone since the handset supports otg functionality then use the pc mouse once you have rebooted into recovery mode. works swiftly!!!!
