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've gone through numerous threads about "unbricking" but I have not been able to find any specific instructions for what to do in my situation. I have installed Ubuntu on a USB drive in order to access ADB/Fastboot and have allowed myself to spend a few days troubleshooting the problem myself, but must admit that I am in over my head and require some sort of guidance if possible. Any insight or help is appreciated.
How I got to where I am:
I believe when I installed TWRP I had to use the build prop exploit, but I can't remember clearly
At some point after installing TWRP, I believe I removed SafeStrap
I installed the CM-11 ROM and used it for a period of time without issue
CM-12 for Thor was released, so I installed it over the CM-11 installation I believe
I realized that by installing CM-12, I had made my gf's save files for Final Fantasy inaccessible
I tried to restore to a backup I had made of CM-11 and was met with a bootloop
By trying to "start from scratch", I wiped all options allowed without realizing the consequences
Any reboots of the device brings it to a black screen after the gray Kindle Fire logo
Here are some observations I have made while trying to figure out a solution:
In TWRP, ADB shows the device as being in "recovery"
In "adb shell" with the device booted into TWRP, the command "su" produces "/sbin/sh: su: not found"
I am allowed to drag .zip files into "Internal Storage" for the device, but flashing "13.3.1.0.zip" or "cm-12 ... .zip", for example, leads to the device booting into a black screen (I have tried mounting /system in TWRP)
Fastboot commands tend to hang on the linux terminal with the device not responding to commands
EDIT: After a little dicking around, I found out how to make the device show up under Windows 8.1 by using a guide outlined here: http://forums.team-nocturnal.com/index.php/topic/1362-how-to-adb-fastboot-in-windows-xp-7-81-10/
I am now familiarizing myself with ADB/Fastboot commands a bit more to see if I can figure anything out on my own.
I haven't been able to figure this out on my own - is there anyone who could give me some advice about my situation?
Basically TLDR is that I did a factory reset on TWRP, I can boot into TWRP but can't seem to flash anything, though I can put zips on my internal storage.

Sound like you either lost write permissions on the system partition or the partition contents are corrupt. I have also heard problems within the data partition can create flashing problems. Have you tried the advanced wipe functions in twrp? You'll need to do a little poking around to determine which items are safe to wipe. Obviously you don't want to touch boot and recovery but (intelligently) neither is an option in twrp.

I get a lot of errors involving /system when I try to mount and then repair or flash anything. Also, when I reboot it often says "Your device does not appear to be rooted - Install SuperSU now?" When I swipe to install it just restarts normally to my white kindle fire logo.
EDIT: I somehow was able to flash the cm11 ROM onto my kindle, rebooted, and my tablet is working again! I tried a bunch of different repair options and even used the option that makes you type out "yes" ( can't remember the name, need to sleep atm), but somehow got it working. Thanks for the help so far.
So I got my shiny new device today, and it feels really nice. I worked with the launcher it came with, tried another one, and realized that yep, I gotta root and install a new rom. The notification bar just annoys me too much as I'm used to having quick actions and other things in there.
So, I followed a few guides, and finally worked my way through to having my command line find my device and can successfully reboot it into fastboot mode.
At that point, I realized that I can boot into recoveries without flashing them first (essentially trying them out to see how it works). However, I tried the 4 official version on the twrp site, and one made by a user here (cuoco92). They all successfully boot into the recover using the command "fastboot boot nameOfFileHere.img". At this point, every single recovery failed to respond to touch and volume presses. I can press the power button to turn off the screen, and pressing power to turn the screen back on shows a locked recovery screen, but I can't slide the screen to unlock it.
This is quite concerning to me. I don't want to flash a recovery for good if it's not working properly. I hope this makes sense. Or, is it normal to just flash a recovery and hope for the best? Do recoveries work with just booting to them without being flashed?
I haven't rooted and/or flashed any devices in about 5+ years, the last being a phone from virgin mobile that supported sd cards. When installing new roms, do we store the zips in the root of the phone, or does this get cleared out/deleted when doing the wipe cache/dalvik/etc?
Personally, I just want to make sure I don't rush into this, as there seems to be fragmented results when searching around for twrp not working with touch. I know these things have been asked before plenty of times, and I hope I don't come across as another "ugh, this again" post. I really appreciate any responses!
you never did, then just leave it as it is...its a nice phone eui is not bad... take it easy
Try booting the official TWRP recovery. As far as I remember, some of the versions tweaked by Cuoco92 had issues with the touch panel.
Anyway, EUI is not that bad, as your were told. While I used it, I also used an app called "Notification Toggles", which lets you get Quick Settings like toggles on notification area. It's nice and easy to set up, and the results, although not the same as having the AOSP toggles, is quite nice and convenient.
BTW, which stock ROM did your phone come with?
I have tried 4 different official twrp files (all from the twrp site). My phone is an x820 6gb/64gb and came with EUI version: 5.8.019S (Stable). EUI is nice, very fast and sleek. Maybe I do just need to get used to it, or maybe it's just me itching to try out the different options available since I finally have a phone is not carrier/manufacturer locked down.
Heyyo, hmm that's very odd indeed! I wonder if maybe by temporary booting Cuoco92's TWRP it could have messed up your recovery hmm...
I'd recommend first to flash the stock recovery over your current one and then reboot to fastboot and then flash TWRP. Hopefully this will erase any problem that Cuoco92's recovery could have caused.
This was the guide I followed and it worked flawlessly for me
https://forum.xda-developers.com/le-max-2/how-to/protocol-backup-stock-rom-flash-stock-t3517151
I never actually flashed any of them. I have only ever just tried booting into them using "fastboot boot recovery name.img". I have not used the fastboot flash command for any of the files.
The only thing I can do after booting the recoveries is hold the power button and eventually the phone will boot up normally.
Remember that I just wanted to boot them to make sure they worked before flashing them. I'll be checking out the guide you linked shortly.
Haven't flashed any of them eh? Hmm should work just fine then... Have you tried TWRP 3.0.2-0 ? I know that one was built with Marshmallow sources
As for which ROM to try? I'd recommend OmniROM if you want to try a custom Nougat ROM.
If you want to see why I think so? I made a massive post or two about it here heh
https://forum.xda-developers.com/le-max-2/help/party-rom-best-help-t3691165/
Thank you so much for the guide you linked. I'm making a little bit of progress here.
I found a twrp recover by cuocos92 that is labeled V3 (apparently from what I read in other threads, V3 seems to be good with the 6gb/64gb models). This recovery allows the use of the touchscreen . Remember that I am only using the "fastboot boot" command so no flashing yet.
Now that I am in a working recovery, I kept hitting "keep read only" so that the stock recovery would not be replaced. I set out to make a backup. Well that kept failing with attempts of trying to mount /system and such. Off to more reading, found out that using the Wipe->Swipe to Factory Reset inside twrp fixes this. I did that. I successfully created a backup.
Now to try to flash the SuperSU zip I have, which was previously copied to the root of the phone from my pc. Can't see any zip files on the internal storage. Reboot the phone (forgetting that it takes a long time after the wipe). Copy the backup to my pc. Copy the SuperSU back to root of phone. Restart the process of adb and fastboot -> back into the cuocos92 V3 recovery. Still no zip to be found. Couldn't mount system again...
Did some more reading. I just attempted the Wipe->Format data. I am currently rebooting back into the phone to set it up again. Apparently, a lot of people say this needs to be done if we did not reboot after unlocking the bootloader. Since twrp has been asking for a password each time I entered it, the format data is supposed to solve this.
I'll edit/post again with more steps or results.
I apologize for the second post here, but this seems more than should go into an appended edit:
After doing the Wipe->Format data, it's advised to reboot back into the recovery. Without flashing the twrp cuocos92 recovery, my thoughts are it would just be back into the stock recovery. At least the twrp version works, so I have no problems with flashing it. And then I'll have to Wipe->Format data again, reboot back into recovery, and then I can flash my SuperSU zip. But how can I get my SuperSU zip on the phone?
Doesn't Wipe->Format data remove it? Everytime I reboot my phone after that the SuperSU on the root of the phone is gone. I can't seem to mount to my pc from the recovery either, clicking the usb storage just unchecks itself right away, and clicking the enable MTP doesn't seem to do anything. So, even if I flash the recovery, Wipe-Format data again, reboot back into the recovery, I still don't see a way of getting the SuperSU zip onto the phone anyways.
I know it probably sounds like I'm whining by now about how things aren't as easy as it seems. I'm trying to be descriptive in what I am doing and what's happening.
Hmm by chance are you using Windows 10? At least I've noticed for me it fails to properly mount the correct drivers for ADB and MTP for TWRP. I'd recommend checking device manager.
If I remember correctly here's what mine looked like at first
https://photos.app.goo.gl/wXaqbi3OeH3bKEf62
Select MTP > update driver > browse my computer > let me pick > (standard MTP Device) > MTP USB Device
Sorry I'm not in front of my PC but I'm sure it's something like that to solve it
If that doesn't work? You can always use...
Code:
adb push ROM.zip /sdcard
Which will copy the zip file to the root of your data storage (on the Le Max 2 much like the One Plus 3 they use /Sdcard as a shortcut since we don't have external Sdcard hardware).
As for system read only? Swipe to allow modifications. Can't flash a ROM properly if the system is read only eh? Hence the failed to mount system.
It's really just there as a disclaimer to cover their ass in case people use TWRP improperly and brick their device. Following green man gaming's guide is safe as I've used it plus many other people as you'll see in his replies
I'd also recommend following the guide and flashing TWRP to your recovery. I only did boot recovery image for backup and then booted to EUI and copied that backup to my PC.
Format data is handy to get rid of encryption and also give you full access to your storage capacity because when I didn't before I didn't get 54.43GB of data storage only something like 40GB.
Tbh I haven't used any custom EUI ROMs but if you're fighting with TWRP? I know Cuoco92's eui has a fastboot installable version
Hope this helps
Well thank you so much for the information. I am running windows 10, but never saw mtp under portable devices, only the phone name Le Max 2. That's ok, as I booted (still not flashed) into recovery and this time I swiped to allow modifications. I still couldn't mount /system but I was able to use the adb push command and the SuperSU file appeared inside the /sdcard directory when looking under Install inside twrp. I swiped to flash the zip, then hit reboot system. Looking in the SuperSU app, I noticed that the setting "Install SuperSU into /system" is greyed out. Well, at least I think it worked.
At this point in time, since things appear to be working, I'll be flashing the recovery and installing OmniRom (it was either this or Resurrection Remix). I think if the play store just works on OmniRom like people mention, it'll be worth it.
So, my steps will be to:
adb -> fastboot -> fastboot flash recovery fileName.img
recovery -> wipe -> factory wipe (using factory to get rid of system encryption) -> reboot back into recovery
recovery -> wipe -> dalvik/cache (do i still need to do this after factory wipe?)
adb -> adb push romFileName.zip /sdcard
adb -> adb push gapps.zip /sdcard
recovery -> install -> /sdcard -> romFileName.zip
recover -> install -> /sdcard -> gapps.zip
At any point do I need to flash SuperSU again? I guess I should after flashing the rom/gapps because, afterall, SuperSU is an app.
Once again, thank you so much for all the information that you have already provided!
Heyyo, it's always recommended to do a full wipe when installing a different ROM so you should format data, wipe system, data, dalvik and cache and then install the ROM of choice with Gapps of choice
Wiping system is OK when flashing a ROM as it'll write into system.. plus there's always the risk of instability if system is not wiped if a Gremlin setting is left over from previous ROM
I'd recommend using Magisk v14.3 over SuperSU as SuperSU doesn't have the same functionality as Magisk for passing SafetyNet...
Plus Magisk is full open source software (FOSS) where as SuperSU is closed source so gotta love that open source (this part is more personal preference since Android is built upon open source and people working together).
Plus there's really cool Magisk modules you can do like ART Optimizer and so fourth if you check the XDA forum section for it
Also, you're welcome! We all had our start on XDA at different points and passing on the knowledge I find is just as important as the ROMs we love
Don't use SuperSU. Magisk is the way to go for rooting nowadays. Easy, systemless, updated frequently to pass safetynet. It's a no brainer.
I 've had a Nook HD+ for years. I don't use it often, but it does come in handy from time to time. Early on I replaced the stock rom with CM 10, later upgraded to CM 11 and finally to CM 13. Recently the tablet started rebooting itself from time to time, an annoyance but not a show stopper. Thinking it wise (I'm not so sure any more), I decided I should reintall the OS using TWRP 3.1.1-0. Typically, I would have launched it from the Android restart menu, but that function was no longer working. So I launched TWRP the old fashioned way using the power an n keys. Then I reinstalled CM 13 in the normal manner. That seems to have made things worse.
Now, from a cold start the tablet sometimes launches Android very briefly, but often it never gets that far. Before the blue marshmallow can stop pulsing on the display, the cyanogen universal bootloader kicks in all over again ... and again ... and again.
I can still access TWRP without a problem. Howerer, I don't have a system backup generated from TWRP, and I can't seem to restore those using the TWRP restore function. I do have a backup of the stock rom made years ago with CMW, so I'm thinking I may have to replace TWRP to restore the stock rom, then upgrade the OS from there. I also have access to another Nook HD+ running CM 10. Maybe I could use that device to create a system backup for my Nook HD+?
If none of these ideas make sense, what are my other options? I'm open to anything and everything. Thanks!
I’ve been unable to solve my boot loop problem, which makes me more determined than every to find a solution.
My Nook HD+ will not launch android. The device launches the Cyangenmod Universal Bootloader, which quickly crashes and relaunches the boottloader, and around and around it goes. I’ve saved backups created using an android app, but those are of no use since I can’t launch android to access the required app. I also have the stock rom backup that I made when first installing CM, but I would need to launch CWM to restore it. So I tried flashing CWM using TWRP. That doesn’t work because it requires a reboot using TWRP to replace the TWRP recovery, and the reboot menu only offers System and Power Off. The Recovery option is missing, a known bug from what I can tell. No matter how many times I flash CWM, when I power off and boot into recovery I still get TWRP.
I also tried booting into CWM from an SD card. But no matter how many times I powered down and then restarted the device, it would not boot into CWM (because TWRP is installed maybe?).
My next idea was to use ADB and Fastboot to flash CWM. I installed everything needed (I think), and tried to install this way, and here’s what I get:
[email protected]:~$ adb devices
List of devices attached
* daemon not running; starting now at tcp:5037
* daemon started successfully
3024900030504303 recovery
[email protected]:~$ adb reboot bootloader
[email protected]:~$ fastboot flash recovery recovery.img
< waiting for any device >
It doesn’t matter how long I wait. Even though daemon sees and correctly identifies my device, the terminal hangs up and never flashes the CWM recovery image. Is it possible that this is because android debugging is not enabled and if so, is there any way to fix this when I can’t launch android?
One other possibility occurred to me (when you read this you will see just how desperate I’ve become). Looking at the internal files displayed when the Nook is connected to my PC (note that my Nook HD+ has not been rooted) I can see an 8.9 MB file named twrp-3.1.1-0-ovation.img. What if I removed that file, put a CWM image file in it’s place, and gave the CWM file the twrp name? Might that allow me to run CWM recovery and restore the stock OS?
I welcome any and all ideas!
Thanks!!
Hi everyone!
I'm using a Samsung gt-n8010. It could be done for due to the age, but maybe there is still hope.
My problem is that the tablet boots always to TWRP recovery and I can switch to download mode as well. Everything seems all right, internal storage and sd card shows exactly how they should, BUT... I can't do anything in TWRP. If I have the Keep system partition read only unticked, it still says the storage is read only and /data/media is not accessable. I can see it and access it with TWRP File manager. I tried flashing ROM and Recovery, also stockROM with Odin, but Failed. Clearing Cache, Data, Dalvik... also ends up with error. Format Data works, and also changing the partition types, but when I reboot device, it all comes back the same as before, no changes take effect. In Download mode I tried to use Adb from computer terminal, but it was stuck saying 'Waiting for device'. If Tab is in Recovery my PC shows both internal storage and sd card, but the internal storage is empty when I open it.
For details: I use Lineage OS 18.1 with TWRP 3.6.1_9-0. On my computer I use Linux Mint 20.3, but I tried with a laptop using Win10 as well, no success.
I've read many solutions on 'Unmodified system partition' or some had 0MB internal storage problem, but in my case that is different, as I have them all, but it seems all is read only and not accessable. I even tried to have the last Backup (2 month old) set using Restore of TWRP, but during the process, the tablet reboots and TWRP comes up again. I can't even turn it off, as TWRP comes up after some minutes.
Please help me somehow to be able to use the Tablet. If you need any further details, just tell me.
TWRP is not out yet on android 12, if you have it as of writing it wont be able to unencrypt your device. So all you can do is use it to install roms (YOU MUST FIRST FACTORY RESET THE DEVICE).
I also have never used odin as I have prefered adb
Code:
adb shell
/sbin/recovery --wipe_data
/sbin/recovery --update_package=SDCARD:romname.zip
adb should work in twrp?
I see your point. I intended to change/downgrade LineageOS version, but I was not successful. Now I am not able to do a factory reset either with success from TWRP, but I give a try to your adb codes. Give me some time

Hi, I gave a try to that code both on TWRP and Linux terminal (from PC). But no effect First I did a FactoryWipe (successful) and went back to the Terminal each time. I tried with ROM zip and TWRP img as well, but after rebooting, TWRP 3.6.1 comes back again. I downloaded Lineage OS 17.1 (with GAPPS pico) and TWRP 3.5.0-9. It seems somehow I got stuck with that TWRP 3.6 and all I get on every attempt of flashing or wiping is it can't see '/data/media (No such file or directory)' or 'Unable to make /cache/recovery: Read-only file system'. I hope there would be a solution to get my system out of Read-only state

Do you have adb installed and do you see your phone when you type "
Code:
adb devices
"
Usually its as simple as just booting into TWRP -> Factory reset then install the rom and done.
Maybe you do need odin but im pretty sure you can use adb instead like I outlined above, I hated using odin but if you find the right file it should also fix your issue.
What is the codename for your tablet? I cant find it on lineageos's site, what guide did you use its an official lineageos im assuming?

Well, I have adb installed, but as my Tablet can only load in recovery it says like these:
adb devices
List of devices attached
4107cd04a2b611b5 recovery
When I load Odin or fastload mode (Download mode as tablet says) I can not list it with 'Fastboot device" command. It says 'waiting for device'.
My tablet is Samsung gt-n8010 (10.1) and I follow this thread to make changes:
LineageOS 16.0 Android 9 for GT-N8000 GT-N8010 GT-N8013 GT-N8020 FINAL VERSION EOL

I had Lineage OS 18.1 installed and maybe what caused the issue is that I did not update the TWRP, or we do not have a TWRP ready for it yet, but currently I have TWRP 3.6.1_9-0 installed and stuck with. As I mentioned, on rebooting tablet always starts with TWRP, asking if I want system read only or not with an Unmodified system partition heading. I can not boot OS at all, I can go to Download mode, but Odin always failed indicating my system is read-only.
Ok yes your device is listed as recovery because it has not booted anything. I'm not sure if the commands I gave work without the system actually booting however.
After you entered adb commands there was no error text?
Also if you cant get odin to recognize your phone (RUN IT AS ADMINISTRATOR) you should figure out that first as thats a last resort fix when you really mess things up which I dont think you have yet. I think you must have something off in your configuration if its not reading anything make sure u can access another phone to rule out your pc, but get this working asap.
Usually if your device boot loops you can wipe the cache, and now days remove magisk modules.
If your device still boots straight to recovery It should be as easy as I outlined above, try not isntalling the apps/plugins after the initial rom, and again make sure you wipe cache/data before hand.
If your device boots straight to the bootloader then your left with Odin.
Man I hate video guides. But it looks good (unless he forgot to wipe) should have been as simple as that. He does not however provide you with the firmware (not rom) file that I believe you are going to need if you improperly downgraded the android a full version number. Post on his youtube and find that firmware file and fix your odin connection and flash it. If odin is also dead I have no idea but I have never in nearly 20 years had a phone fully brick even when I try to brick them. But I know it can be possible but your most likely going to recover from this.
If he doesn't respond just read more and learn, you may need some specific large file though to flash over what I believe may now be missing partitions entirely.
Maybe someone else here can help too. Good luck!

Hi there, I actually find some videos or instructions useful and some helped me out a lot. But as always, things can only be proper if anyone is qualified to do it or when you have the exact same issue on the device. Now back to my case...
I tried many ways, many aspects, but none helped me out. There was this good and working Samsung 10.1 gt-n8010 and one afternoon I found it turned off. When I charged it for a while I turned it on and all it could load is TWRP and I could not do anything. It seems to be working, but I could not see internal storage, while it showed all the 12 GB amount I had, so the issue is not that it shows 0 GB like in many videos. I tried to wipe cache, data, system, even change partition types, all ended with a fail saying my 'system is read only'. I also tried to use Odin and Heimdall to flash new recovery and ROM, also gave a chance to stockRom with android 4.1 or 4.4, but in all cases it said FAILED. To conclude all: I think it could be a hardware issue and as the machine is more the 10 yrs of age, it would not be a surprise, but it's a same it can't be flashed.
If anyone had a similar issue or may have suggestions I'm all ears and the thread remaines, but I am out of ideas at the moment and put my Samsung tab on the shelves.
