[Teclast X98 Air 3G] :
after you use the tool report back on whether it worked or not, what have you flashed (bios and rom), if you have you made any changes in the partitions (delete the EFI one for eg?)

considering that on some devices (same model) it works while on others it doesn't i need some more info in order to figure what could be that triggers this different behavior.

the link is in the OP first post
[Teclast X98 Air 3G] k2wl:
I first flashed v7.0 rom and then i couldnt get into windows. so i flashed 2.0.5 bootloader.

then its bootlooping into red chinease logo.

following error comes when i follow OP procedure.

this error pops up when i follow above procedure.

Hello guys!

ionioni here is my first attempt screenshot if you could remember - somehow I could not find the sent messages in XDA Private messages folder /WHY?? - I sent you. THIS IS the SAME! But there was now problem... and it has rebooted, and you wrote me something but could not remember what.
[Teclast X98 Air 3G] florent.m:
Thanks Blackbile& IonIoni to help us!!!!

hope you can remember the magical trick you use to recover your brick and hope the solution will be the same for us!!!!

thanks a lot,

[Teclast X98 Air 3G] k2wl:
strangly i can boot into bios settings via connecting usb keyboard and mouse. and pressing ESC button.

does this means anything??
[Teclast X98 Air 3G] blackbile:
Hi florent.m and k2wl!!!

k2wl if you can enter into the BIOS this is normal otherwise we can't repair the BIOS... I think.

Here is my idea: boot into BIOS with Escape or Delete AND there make "RESTORE DEFAULTS" and "SAVE CHANGES AND RESET".

After that try again the restore procedure!

Waiting for the result....

*******************************************

florent.m

I see your uploaded BIOS, and I found that it is the same as ionioni used for restore, it means that it has to be good for you restoring.

BUT you don't try flashing back your saved original BIOS - if you restored your tablet and it works - because at 400DH 400EH address there are FE FE datas, it has to be changed FF FF with a hex editor!!!

I don't really understand why it has to be done, I did it before I sent the clear 2.05c BIOS to ionioni.

*******************************************

There is very questionable thing in Mirek 7.0 package - the BIOS update, I read in the thread, that he use for flashing the 2.05b version, so maybe that is a big trap for the C5J8 owners, as here are 2 people who did that Mirek tool reflashing and his tablet bricked!

I think for C5J8 the perfect and ONLY USABLE BIOS is 2.05c version!!!

[Teclast X98 Air 3G] blackbile:
What happened exactly? Colud you send me screenshoots in PM because <10 posts you can't post pictures or something...
[Teclast X98 Air 3G] blackbile:
I have a question:

what happened exactly when you tried to restore the BIOS? You wrote the 2 commands as in the OP and did you see the screenshots as I did, or the tablet did not reboot at all after the 2nd command???

******************************

New idea!

What commands did you use for restore??? I found another mistype in the OP - I'm sorry.

You see 2 red rect in the attachment, which command did you use:

1. from the 3. point

or

2. from my log (command window screenshot)?

Unfortunatelly the 2 was not the same (in my command window screenshot there was the first version restore command string)!!!!!!! I edited now is the same.
[Teclast X98 Air 3G] florent.m:
Really thanks Blackbile for suppor you give us,

here is the complete storyboard I apply to my tablet,

then you can see, we never go in the bios tool app :((((

while on the pc side, all seem to be right

hope it can help you to remind!

may be you can also a copy of your old tool, and I can try it

also, I ad a screenshot of my bios, my be some info on it!!!

thanks again,

Cheers, Florent
[Teclast X98 Air 3G] k2wl:
this is exactly same Screenshots from my Tablet.

bios is exactly the same.
[Teclast X98 Air 3G] blackbile:
Well, your bricked state is NOT as mine was!!! You are on a 2.05b BIOS at the moment as I see on your picture, is the tablet continously rebooting?

Could you flash the Android by Mirek tool or MFT in DNX mode?????????? If yes than I dont understand why you could not restore, if no, then I have no more idea... did your try the previous ideas from me?
[Teclast X98 Air 3G] k2wl:
I flashed android by MFT in Dnx mode.

which previous idea??
[Teclast X98 Air 3G] blackbile:
Post 26. and 29.

Could you flash it now from DNX mode?
[Teclast X98 Air 3G] k2wl:
i can't flash.

i tried both . but both failed.
[Teclast X98 Air 3G] :
for some reason (that i can't know not having any of these devices to test) the same model that bricked in the same way refuses to load stuff that works on other models (@blackbile no, the old tool is the same identical one, in this later one i just managed to enable the status messages). i think that has to do with 'the way' the tab was bricked and more exactly the rom that was flashed (and the options available).

anyways, like i said, since i don't have the device (not any Teclast) it's cumbersome for me to try all kind of stuff in order to 'align' the restoring tool for all. problem is that the dnx loader/boot image combo doesn't work on some of the bricked tabs so i have made another variant that will bypass all of these. i compiled an (only) EFI binary loader and packed in it the stuff needed for the bios restore (so no longer it needs to boot a kernel or use the stock loader). so far i made the restore (from EFI) tool for the C6J7 variant (and was already used by a user who had this not'working problem with the first restore tool).

as the skeleton EFI app alredy exists and working is not very hard to compile it to the other models

so in order to do it i need owners of the other models to work with (this is easy now but i still need to check)

1. you have the original(working) BIOS file for your model and you are sure that is the correct one

2. you have some messaging form available (i will NOT answer pm's from an owner that doesn't send a skype contact or similar mean of communication, NOT email!, you do know what real-time messaging is no?)

DO NOT pm me unless you have the above two points, again i need some owner to test with (and after that he will post and explain to the others)

that's it, the C6J7 BIOS restore 'the EFI way' is tested and working, so now i might make similar ones for the others but...
[Teclast X98 Air 3G] k2wl:
i have PM you my original bios file and my messanging details. thanks.i hope you will succeed in this..
[Teclast X98 Air 3G] florent.m:

Hello K2wl,

I see your message on the other post, but I Cannot understand neither what you are requesting,

nor the way you recover your brick thanks to the help of ionioni.

if you need my bios, the one I post above, is the one I get directly from the Mirek tool. before flashing. and I let this version untouched.

So, please, Could you explain a little bit more?

Thanks,

[Teclast X98 Air 3G] k2wl:
I mean to say, ionioni worked on my original bios file which uses EFI loader for flashing.

my bios is kind of locked state and which is not good. he said some way i need to flash "free bios"

and i want you guys to share your original working bios files.which he will match with my orginal bios.
[Teclast X98 Air 3G] blackbile:
Send me your original BIOS!

I don't really understand that could you restore your BIOS or not?
[Teclast X98 Air 3G] :
actually, what i suggested was that you seek for information from the others on whether after flashing a BIOS that was not modified (still with 'FE FE' when flashed) can somehow run you into troubles in the future.

whether you will want to flash again with another 'modified FF FF' BIOS file (if i recall flashing a 'FE FE' BIOS should have bricked your tab yet it did not) it's up to you and i was telling you to make that decision after you get more information on the matter from the others.

imo the 'if it works don't fix it' should apply here ...
[Teclast X98 Air 3G] blackbile:
ionioni: did you restore or not?
[Teclast X98 Air 3G] :
already there

as a personal curiosity, can anyone confirm that flashing his backup BIOS file (having the two FE bytes in there) has bricked his tab? and even if he bricked,how can he be sure that the reason was this one? seeing this 'mandatory' condition on your device i checked my BIOS backup and it also has the two FE bytes in there, yet i never bricked my tab tho i think i flashed it at least a dozen time (i have a Yoga Tab 2 but is a somehow similar Baytrail hardware with the X98)... so i wonder is this 'mandatory precondition' checked by anyone? an x98 owner that has a BIOS programmer could also double-check easily (and safely) by flashing a BIOS with 'FE' and with 'FF' and confirm that he bricks on 'FE' and he works on 'FF'.
[Teclast X98 Air 3G] k2wl:
Basically and frankly speaking i dont much understand what he (ionioni) said. so there is confusion in my saying.
[Teclast X98 Air 3G] florent.m:
Hello all,

Lately back from work!

but it seems that you have some good news?

the basic question, is 1st dedicated to K2WL,

Is your tablet dead or alive?

and if alive, could you tell us how to do?

and for sure thanks to Ionioni & Blackbile for your support!

Hi [MENTION=997923]ionioni[/MENTION], my device (C5J8) got bricked flashing the 2.05 BIOS with Mirek's utility. I have found your solution for which I am very grateful but I cannot get my Teclast recognised by Fastboot although is in DnX mode.

I have a soft brick with the red chinese logo.

My device looks in the device manager like this:

Thanks a lot in advance,
[Teclast X98 Air 3G] Gitanitos:
Have you checked the battery level? I had the same problem some days ago but using this guide I unbricked directly.

Maybe you can check the path in the command window, it's the only thing difficult to understand of this method (I'm a real noob...)

Good luck

Well, I've got the fastboot to recognise my device by updating Intel drivers but I cannot push the file when I execute the second command. No errors are shown:

EDIT:

Finally I managed to push the file but I am having the "get_path:334" error. In the PC looks fine though.
[Teclast X98 Air 3G] florent.m:
All, hello,

and first, thanks a lot to ionioni!

yesterday night, he was able to bring back my tabletup to life!

really, really impressive and efficient!

after some basic tests, he get my bios file an then with a new loader, he was sending me a package able to flash back the tablet.

the procedure is more or less the same as the one described on the first post of this thread, but with the files modified.

so Al-Azraq may be you can wait what is ionioni statement,

if he tells it is 'safe' for every one (your tablet & my privacy) I can write a new post with all this package

and

he didn'nt prefer to do it in another way !

so you have now to wait a litle bit more before an answer, but seems that solution is not so far away!

and again, thanks a lot to IONIONI and to Blackbile for your support!

Cheers,

Florent.
[Teclast X98 Air 3G] blackbile:
After seeing that there is some differences between the bricked status I have a solid idea:

!!!FIRST thing to do - before you brick your tablet :D - save your original BIOS!!! AND change data from FE to FF at address 400Dh and 400Eh with a hexeditor!!!

1. Bricked 1 status

as mine, I had another think about my bricking - unfortunatelly I did't remember exactly - I had 2.05c from factory, I have not got GPS therefore I tried to flash the ver.2.02, BUT the result was not good as the verify found differences. After that I DID NOT power off the tablet because it could brick it. Rather I flashed back by FPT my saved 2.05c BIOS.

And I think that here is the key - my previously saved BIOS has FE FE at 400Dh and 400Eh address!

Bootloop with Teclast red logo, I could enter the BIOS, I could enter into DNX mode.

ionioni's first restore package work for me.

2. Bricked 2 status

I think here are the others, who flashed 2.05b by Mirek tool - assumption!

I don't know what BIOS was before on this tablets, what did the owner after flashed the 2.05b... etc.

ionioni's 1st restoring tool (but ver.2) give a "get_path:334" error

ionioni made other tool for this brick status and it seems working!!! BUT nobody shared it yet...

***********************************************************

I'm working on 2.05c BIOS unlocking.

I have a modified BIOS, but I did not dare to flash it... :silly:
[Teclast X98 Air 3G] florent.m:
Hello Blackbile,

Yes, the second bricked status seems to be the same for many of us,

for sure IONIONI magic potion will likely be able to do the trick, but as it seems to be a draft version, with the belonging risks, I didn't want to post it without his authorisation,

(for example version I have didnt answer nor react at the end of the flash during the verification phase -> was ok for me as I accepted the risk of deeper failure....but it's not a no-risk tool!!!)

hope you can all understand, even for sure if I understand well the pressure and the weight of the brick!!!! ;)))

and for sure I'm closely following your posts regarding the gps which is also missing me a lot on this device :((((

best regards,

Florent.
[Teclast X98 Air 3G] Al-Azraq:
Great news! I am very glad that you were able to resurrect your half dead tablet.

So I will patiently wait until you say so. You are amazing, thanks a lot for your efforts to all of you.

And yes, I have bricked my tablet flashing the bios 2.05*with Mirek's v7.0 and, if I enter the bios, it says that I have 2.05b version.

If more test is needed, I can work as guinea pig [emoji28]

BTW, I have my original BIOS backed up.

M5C5 (Air 3) also not able to boot

Hi there,

sadly i have the same problem after updating my bios (Version 2.05) with the mirek v3 flash tool. I have a backup of my working bios. I tried every method posted here. Nothing lead to a working state.

What i tried:

- Used the files and procedure of the recovery of my model number (m5c5)

- Used the files and procedure of the recovery of my model number (m5j8)

What is working now:

- i am able to enter the bios

- i am able to enter the DnX Mode

What is the error message:

- when i try to reflash the OS it show the error_path:344 (...can find boot handle.....) error message

I uploaded my backup bios at drive (contact me for the link). Could you please try to create a working file(s) for me?

Thank you
[Teclast X98 Air 3G] Al-Azraq:
I am sad to read that you had to same problem as many of us.

If you read previous posts, you will have some good news as it seems that [MENTION=997923]ionioni[/MENTION] was able to develop a package that is able to fix our devices. [MENTION=6943103]florent.m[/MENTION] managed to recover his tablet which was bricked for flashing the BIOS 2.05 using Mirek's v7.0 tool. I think that they want to be sure that the tool will work 100% sure and then they will post it.

So a little bit of patience as the fix is on its way! :)
[Teclast X98 Air 3G] blackbile:
Yes, I flashed the modified BIOS several time this afternoon... no resolution. :(

The other functions did not show up, after reboot only the "Recovery" option show up which - it seems too me - wanted to recover something automaticly, but could not success.

In short term: our BIOS is an AMI APTIO V and the latest AMIBCP tool which I could get on the net is ver. 5.0.1.0014 with this utility I could not unlock our 2.05c BIOS.

Make sure you have the correctly sized bios_file. It took me a couple of tryouts to make it start, but then it was finally done.

You find all needed files and tools in this thread. I will summarise them later on...

Now I have a proper brick!
[Teclast X98 Air 3G] MAGIo18:
How the hell could I create a brick flashing a proper BIOS to my tablet?
[Teclast X98 Air 3G] :
i can think on a few reasons...

1. you said that it 'took a couple of tryouts' and you mention about the 'correct' size of the bios file... what do you mean? the bios file on these tabs is always the 'correct' size, have you modified something in the process of making it to 'work'? maybe link the signed file

2. everyone thinks that the risk is when writing the bios, to 'lose' somehow a few bytes during the operation, but actually that cannot really happen the way this tool works. the risk is of losing a few bytes when making the bios backup and this one goes undetected, because usually nobody makes the verify after to check that the backup file is the same with the bios was dumped from. also consider that the flashing operation is followed by a verify one, so you can be sure that the file you flashed was really flashed correctly and also because of the md5 signature you can be sure it is the same one you have on your pc and you had signed (this was one of the reasons i added the md5 signature, the file content is checked against the signature and the tool will abort and show an error message from start if non matching)

3. this is the most generic one, a bad bios file and is so easy at times to have one
