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 ?
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

Hey guys, I'm facing an issue right now.
I had a rooted OPX with TWRP and Lolipop. I downloaded the new OOS 3.1.3 from OnePlus site, flashed it. There was an error, fixed it by updating updater-script. Flashed the zip, then just after that flashed SuperSU zip and TWRP image over recovery. I don't know why I did that but that's the order. Then I forgot to wipe Dalvik/Cache and rebooted into recovery...It stuck in OnePlus Logo screen with powered by android written at bottom. Then I tried to boot into System by pressing the power button, it got stuck in the boot animation (The new one in Marshmallow update). It just keeps rotating infinitely (I think). I have waited for about 30 minutes on that screen, no luck.
What should I do? Is there a way that fastboot mode would be recognized by my PC and I can boot into recovery via image? Or any way for factory reset? Data is all backed up, so no issue about that. Just need it to get running asap.
Please reply asap.
Thanks for reading.
Did you try booting into recovery or fastboot manually ?
For recovery - hold all 3 keys, when OnePlus logo comes, then leave Vol Up key and hold the other 2.
Do the same but leave the Vol Down key for fast boot.
If either of this works then you can recover easily.

Just as I mentioned, booting into recovery doesn't work. Stuck at the OnePlus Logo Screen if I do that manually.
Though I can boot into fastboot. But after doing that, when I connect the phone to the PC, fastboot devices command returns an empty line.
We get so caught up in custom recovery and such that we forget about what people would normally do who don't mod. Simplest safest way to upgrade bootloader or downgrade is by using original stock recovery. Now your gonna probably need to go through the hard brick guide.

Yeah, I did for the first time.
I think I now know what went wrong. For future viewers -
Do NOT ever Flash Recovery Image through your recovery. Always use fastboot.
Something weird happened. I managed to flash recovery, update to OOS 3.1.3. Then for rooting, I downloaded TWRP and SuperSU zip from the links here http://forum.xda-developers.com/oneplus-x/general/discussion-how-to-root-oneplus-x-t3242830.
But as soon as I flashed SuperSU, I got stuck in Bootanimation again. Why is this happening??

You have to use the modded SuperSU. You can find it in the many guides posted for oos3.
Hello,
I started on a quest last week to try and make my long forgotten Xperia tablet z LTE SGP321 more user friendly.
I stopped using it after being frustrated by the bloatware and its lack of customisation.
So I thought flashing a custom rom might help and wanted a bit of a technological challenge. Boy do I feel like I've got one.
I used kingroot, which worked fine. I tried to install SuperSu but it wont update the binaries.
I've managed to unlock the bootloader (forgot to do the backup TA woops!).
I downloaded TWRP app, flashed pollux_windy to recovery. Now there doesn't seem to be a combination of keys that I can find to boot the sony xperia tablet Z into recovery?? Power and volume up or down or jamming both keys...nothing seems to work. I've found one forum post suggesting it isnt possible and that I need to flash a kernel which is where I'm getting stuck.
SO this is where I am now and was wondering if I should use CWM instead or if there is another way to open recovery?
My main aim is to completely clear the tablet hard drive and start again with a custom rom.
Thanks!
>>>>>>
NEW info
So i've managed to use the ADB to reboot into the boatloader. All that happens is a black screen. I want to try and flash CWM or TWRM but it doesnt seem to work.
Im beginning to think there's something strange about the sony xperia tablet z in that it doesnt have a bootloader in its stock firmware. i've seen something about using a Kernel approach but the guides are unclear.
Any help on flashing a CWM or TWRM into recovery would be much appreciated!!

Flash boot.img of any latest custom ROM with TWRP integrated.

Thanks for your help. I thought I'd start simple and just try and flash TWRP to recovery.
i downloaded the latest TWRP pollux windy img and then used the command fastboot flash recovery twrp.img
It says FAILED (remote: command not allowed)
adb fastboot devices displays my tablet
(by the way in configuration in service info it says bootloader unlocked: Yes)
>>>>>>UPDATE
so i managed to flash a cyanogenmod img using "fastboot flash boot boot.img"
The device then soft bricked and went into a boot loop. Is this because I used the wrong version of cyanogenmod?? Any other I can try that work?
I panicked a bit, mamanged to get the tablet into fastboot somehow andthen flashed a TWRM img to the boot using the same command above which now loads TWRM.
fastboot reboot now caused the device to go into TWRP but its in recovery mood
How can i undo that step i did when I flashed the boot img of the cyanogen mod. I want to put the old boot.img back!

also can I ask another quick question of you, what do you do to boot into recovery on your xperia tablet Z device?
Thanks!
Sorry about all the updates.
I decided to see what you had installed on your signature and tried resurrection remix. Version 5.8 caused Error 7??
So i went for version 6.9 which i installed successfully.
Only way i know how to get into recovery is to use adb terminal command "adb reboot recovery"
Also before I installed resurrection remix would you recommend a complete wipe of everything or does it not really matter?
Thanks and hopefully that's me all sorted!
Use VOL+ or VOL- on boot to enter recovery.

2 way for me:
- usually you can set an "advanced reboot menu" under developer option or the ROM customization panel (depends on which ROM do you use)
- turn off your tablet, now push the power button until your screen just turn on, leave the power button and start pressing vol+ and vol- alternately until you boot into recovery
Hello everybody,
Im totally new and have a big problem.
I rooted and unlocked my phone (HTC one m9), to install a costum Recovery (Team win)
I followed all instructions and copied viper rom on the phone.
After installation, I got into the bootloop.
I can see white HTC Bootscreen with the red instruction ..."This build is for..."
I know, that my phone is not able to boot new image because S-Off is not enabled.
Now my question.
Whats the best way to get a solution for this problem.?
I can boot into download mode or get into my costum recovery.
ADB and platform tools are installed on computer.
Need help. please!!!
Factory reset seems to be it. Thankfully something pops up, instead of dead. There should be a option( you may have to look for it on xda) to get into the stock recovery, through a combination of button presses. On my phone, volume up, and power button gets me into twrp, volume down and power button takes me to the stock recovery. You may have different cadence for your particular phone, so finding that out is a must to return to stock, which you can start over again. I couldn't even root my phone, with out installing twrp first, so I had to get the unlock code, to unlock it first. Some phones may have a different way to root, without unlocking the bootloader first, but start over, it still turns on. Whatever you have had will be lost, if you didn't backup somewhere before you started to install twrp, because it won't boot into the os, that info's gone, and you have to go back to stock, to get rid of the garbage that would still be there from the failed attempt. Trying to install twrp, without doing that may corrupt your partitions, then it may get bricked beyond repair.
What are the necessary steps i have to follow?
Relock Bootloader?
Flash firmware.zip?
how do i flash stock rom?
Im not able to star my phone.
only workspace is recovery and ADB via PC...
Help please!
