A. if you have a backup:

1. download and extract the zip file attached (files required to go in fastboot mode)

2. download and extract the TWRP temporary recovery from here

3. power off tablet, the start in dnx mode: press and hold both vol keys, now short press pwr to start (release pwr when buzzing but keep vols pressed) in a few sec screen shoud say "Fastboot starting.." and freeze on that message (you can release vol buttons now). you must have the "Fastboot starting..." before moving on (repeat from power off if not)

4. open a command window and issue these commands (using the files in the zip file attached)

fastboot flash osloader bootx64.efi

fastboot boot droidboot.img in a few moments you will be started in fastboot mode

5. go in the extracted IntelAndroid-FBRL-07-24-2015 folder and start the launcher.bat file, choose your preffered recovery mode (TWRP?) and as a trigger use T4

6. restore

B. i don't know what kind of backup do you have, however the bios gets displayed mostly when something is wrong on your ESP partition and if so you can restore it using the esp.img file from here by doing this:

1. go in dnx mode (steps from p. 3 in A.)

2. start in fastboot mode (steps from p. 4 in A.)

3. issue this command after you are at the droidboot menu

fastboot flash ESP 1380f-esp-original.img (or use the patched one to unlock too)

C. should none of these work for you you can do the get back to kit kat step and this will work for sure (it's safe to do it 100%)

Up and running!

Whoa thx for that !

But i have to admit i guess i over reacted, when i woke up i turned the pc on and after connecting the tab the battery screen turned on and i heard the usb on the pc connect! I guess the usb connection was acting up or something after multiple connect/disconnects ?

Anyway, after the usb did connect i tried using the Intel FB_RecoveryLauncher and it actually worked! I then fully recovered from my previous nandroid backup using twrp.

Even better, i went back to the xposed page here on xda and downloaded the latest x86 build (sdk21) + the alpha 4 installer, installed and flashed the zip, now everything is working 100% OK.

Again, thanks so much for your quick response and solution.

And to anyone in the same situation, please, use this information to your benefit!

congrats.

question... how did you flash the xposed zip?
[Thinkpad Tablet General] Sinista2015:
I used the Intel FB_RecoveryLauncher (has built-in TWRP+CWM) :good:

1380F Hard bricked - Need help

Hi Friends,

Looks like i have hard bricked my new 1380F Yoga 2 Pro. I had upgraded my yoga to Lollipop and was trying to downgrade to kitkat. I followed the instructions and i got a message flash OK then some text scrolled on the screen and screen went blank. When i press power on button nothing happens. When i charge, only poweron button light keeps flashing. PLease help

Raju
[Thinkpad Tablet General] :
really? on what screen? the tablet screen is frozen when the exe tool asks you for the final confirmation and gives no more messages once it started the restoring process until it reboots (see attached how the tab screen looks and stays on a 1380 tab, and for sure no 'flashing is ok' message there, it is impossible to give any message as the droidboot service is stopped and adbd doesn't output nothing to the screen during the process, moreover the ux interface is inactive...) did you really run the kitkat restore tool? i guess not. did you had the screenshot i attached on your tab? i think not

next time when you say that you followed the instructions make sure you post your message in the thread where you read them from, not some place else. you did not used the downgrading method from this thread but another one, yet you post here as if you do it something will change (and i am pretty sure of it considering that you say that "some text scrolled on the screen and screen went blank" and this is not what happens when you use the tool i made, yet a method described in another thread has similarities with what you were describing so go and ask for help where you read the instructions not here).

no intention to be mean, i do understand how frustrating this can be, yet when you have a problem it's better to talk with the one/at the place where it was generated it, not throw it in a completely different place.

@ others: i made sure that NOTHING can go wrong, once the restore process on the tab is started it will finish and reboot at the end (the restoring process that runs on the tab won't start flashing until he rechecks the files internally, also when done it will check again read/verify the bios for what was written and only then reboot the device). i took care that the restoring process running on the tablet won't ever get interrupted (even if somehow the usb is disconnected it still goes on restoring and rebooting at the end), only two things can go wrong (and to make them one must really be ...... considering that they are against even the common sense not to say about how many times in the thread and while the exe is running the user is warned not to make them ):

1. the user forcefully powers off the tablet during the process which can (but not necessarily) cause the bios to be partially written, all depend of the moment he did that stupid thing (but why would he?)

2. the user flashes by mistake the other version of the bios (there are only two files... so come on...) yet i don't know if this would hard brick, could still be working(with some penalties) as they have identical hardware yet the screen could be affected and not display properly during the boot (but it's better not to test things like this)
[Thinkpad Tablet General] rajan2002:
Hi Dear

my apologies. am new to XDA. you are right. i tried using your tool but my tab was not recognized. i tried installing drivers. then i tried another method which showed success but now tab is not rebooting. only power light keeps flashing. My sincere apologies as its not your method.

I should have been careful in knowing what am i getting into. looks like i have bricked my new Yoga tab. I tried disconnecting power cable by dismantling back cover but no change.

You are an expert and hence looking forward to your advice.

Once again pardon me

Regards
[Thinkpad Tablet General] :
no need for that, i was somehow caustic, but you got me confused about what you wrote...

again, i understand how annoying this can be (i hard-bricked my tablet 2 days after i bought it by flashing the wrong bios then i waited one month for the needed/ordered bios programmer to come from china, sending it to Lenovo for repairing was not an option because i knew i would hard-brick it again after it would have came back and boy did i bricked it... i think i reprogrammed the bios 50 times).

if your tablet no longer buzzes when you press the pwr button then that's it. i wish i could say that there is a solution, yet if there's a wrong firmware nothing helps, you can disconnect your battery but the firmware that is stored in the bios stays there (you can as well un-solder the bios chip and solder it back on and still it will be the same stuff in it). only thing that can be done is to program the bios again with a good firmware but this can no longer be done by software means (flashing from outside) it can only be done by physically attaching a connector to the bios chip and program using a hardware programmer (this is what they will do even at the repairing service at lenovo). it can be done, i did it, yet you must have the know-how and the programmer required, also the components are small and is a small working area, the chances of bricking for good your tab (physically) are high, so you should take your tab someplace where they can program the bios safely.

considering that is a new one, in warranty, just contact Lenovo (be angry :) ) and send it at them, they cover the sending/packaging and they will repair it for free (you should 'forget' to mention what you did, they don't care, just tell them is no longer starting) or find some local repairing center... the thing is easy to be done when you have what you need (dismantle/program/assemble back takes tops 10 minutes) but it can also go very bad when is done by someone without the needed stuff... if you're doing it locally tell me if you need the bios or some other advice
[Thinkpad Tablet General] rajan2002:
Dear Ionioni,

Really appreciate your guidance here and thanks for your help.

My situation is like this. When i charge the tab, light keeps glowing but when i press power button nothing happens not even vibration/buzz.

I bought this on ebay from Korea and am based in India. No luck on warranty as international warranty is not available.

Past few days i did lot of research on google but in vein.

I saw one user suggesting shorting GND and Pin 2 on BIOS. attached Picture.(Similar winbond BIOS)

I have not yet tried this. Any help on BIOS will be highly appreciated. If i am lucky getting BIOS, is it just replacing BIOS will i be able to recover?

You are an expert and hence your guidance will be of immense help

Regards
[Thinkpad Tablet General] rajan2002:
Dear Ionioni

Thank you for a very comprehensive guidance and taking time to help me. I did contact Lenovo but they insist they cannot service it in India but they did give me local repair center details where i can try repair by paying charges. Am visiting the repair center today. I will also also take copy of steps given by you. Will be great if you could provide files to be put on BIOS.

As always i really appreciate your help and kindness.

Regards
[Thinkpad Tablet General] :
Atached. You can either:

1. give them only the bios file and after they program your bios with this is possible that you need to flash the kitkat stock rom when coming back (if you android files were not fine when you bricked) or

2. you can also bring them the whole kitkat stock rom for the 1380F model, so that they will also flash it on the tab after they do the step 1, but this step can be done by you too

If you think they will charge extra for flashing the kitkat stock rom too, then give them only the bios file and you can flash the stock rom easily when you come back home with your tablet (if the tablet starts after you press Pwr then it's ok, doesn't matter if it boots in some error or stuff, as long as it starts/buzzes and shows that white Lenovo logo you can flash your stock rom)

Good luck!
[Thinkpad Tablet General] rajan2002:
Dear Ionioni

Thank you so much for the BIOS file. I will take this to service center and report back status. So nice of you.

Regards
[Thinkpad Tablet General] rajan2002:
Dear Ionioni

Hard luck. Service center mentions motherboard needs to be replaced. I guess they want to make money. I need to now see if anyone can program the EEPROm. By the way is this Nano usb programmer will work with winbond 25xx chip
[Thinkpad Tablet General] :
such scumbags... or maybe they don't know how to program from zero. did you possibly bricked something by your exploring? i doubt.

the bios is programmed in a flash memory W25Q64DW (WinBond replaced it with FW, same thing) 1.8V flash 64Mb (8MB) SPI nand memory, you don't need to buy it as it's good it just needs new firmware on it (i bought myself back then a lot, was some 2$ for 10 pcs still have them someplace, never used one as it was not the case).

i don't know about that programmer (i doubt it programs at 1.8V, most likely is a 3.3V one)

any 1.8V programmer should do (no 3.3V or you risk blowing stuff on that area).

did you worked before on electronics? or at least have a buddy to help you?

can't you go to a phone repairing or something? i mean come on... there must be someone in your area that can program a 1.8 flash memory... wth
[Thinkpad Tablet General] rajan2002:
Hi Ionioni

So far no luck on the EEPROM programmer [MENTION=4149147]1.8[/MENTION]V. Am going to try my luck at Bangkok during vacation. Jsu to be safe side i was looking getting Bios chip but am not getting exact chip. My tab chip reads as 25Q64FWIG. Attached picture. Is this SOC8 or WSON8 or QFN8. On Aliexpress am getting WSON8 and QFN8. Kindly guide

Regards
[Thinkpad Tablet General] :
you do NOT need to buy the chip, before you will destroy the chip you will destroy the whole mini-board and in that case your chip will be of no use anyways...

[Thinkpad Tablet General] rajan2002:
Hi Onioni,

At last i was able to get back my tablet in working condition !! This would not have been possible without your guidance.

I took this tablet to one hardware engineer and he was able to take off the chip and reprogram it using file provided by you. The moment freshly programmed chip was put back, tablet started on Lenovo logo but was getting into constant loop. The good part was my PC was recognizing the usb connection. I then used ADB commands to reboot into recovery and finally i could get into Lenovo recovery menu wherein i used wipe cache option etc and Tab was back on Kitkat without any firmware flash.

Thank you so much for all your help. May god bless you !!

Regards

[Thinkpad Tablet General] :
good to hear... in the future you know how to downgrade your bios :)

you can flash stock kitkat rom safely just so you know youre just as new, the operation has nothing to do with the bios
[Thinkpad Tablet General] Eyecare:
I have all drivers installed, rebooted pc, I'm getting the "Fastboot starting..." message on my Tablet, but when I run the RESTORE-KITKAT-BIOS-830-1050-V2.EXE, and I choose "C" to continue, I'm getting an error message "error when flashing osloader, have you started in DNX mode? .... press any key to exit".

My tablet is Yoga Tablet 2 830F, on Lollipop (latest official rom)

I'm running Windows 10 x64 on my pc.

Thank you in advance.

ps. I think there's something wrong with the iSocUSB driver, as it won't appear on my device manager. The only thing I see there when I connect my tablet is the Intel Android Device. Though, in my programms, that iSocUSB driver looks ok.
[Thinkpad Tablet General] :
run the tool from the C: drive (easier i think is to just copy and run from desktop), there is a minor bug in the restore tool script that makes him not find files on other logical drives
[Thinkpad Tablet General] Eyecare:
thanks, that worked

for 'le connoisseur' dnx(efi) mode bios flashing tool
[Thinkpad Tablet General] OskuPosku:
Hi!

I have Yoga 2 1050-L. I successfully restored KitKat BIOS and flashed KitKat ROM. Thanks for the tool ioniioni!

My ultimate goal was to get a fresh new Lollipop system without root. (by downgrading back to KitKat and then upgrading to stock Lollipop through OTA).

Unfortunately now I have few problems with OTA/country set and mobile data. I've already tried few different KitKat versions. This is what's been going on:

I tried to change my country set with ####6020#. At first it popped up with a message "Cannot read OTA patch from sdcard... blah blah", so I threw easyimage.zip on the internal storage and it worked and I could select my nearest country from the list. Then my tablet rebooted and went to the original Lenovo recovery and started an update. It went fast thru with a result "Update failure". It didn't change my country set.. still it's set as "Unknown". All OTA updates fail too.

Another problem is that I cannot enable my Mobile Data connection. Nothing happens if I select it from the menus. In settings Mobile networks is grayed out. Still the device recognizes if I insert/remove a SIM card, and lets me unlock it with PIN, but in status bar there's always network icon with a "X" on it. I've tried with different SIM-cards without luck.

I've flashed many roms (not BIOS though) on this particular tablet in the past, never had problems like these. I don't understand what has changed.

Hoping someone could help. Thanks in advance. :)
[Thinkpad Tablet General] :
i am assuming that the restore kitkat bios was successful (as you said) and you did not updated to lollipop meanwhile. flash this (from DnX mode, PwrOn with both Vol keys pressed, screen says "fastboot starting...") after you flash remember to set the country code ####6020# in Contacts before you attempt to take the ota's) and then take all the ota's when prompted
[Thinkpad Tablet General] OskuPosku:
Thank you for your response, ionioni. :)

KitKat bios flash was successful indeed and no Lollipop updates meanwhile. I have already done everything exactly as you tell me to do now. I think I've even tried that particular rom you linked (found on another thread), with no different results than other roms.

Anyway, I have good news: I managed to get the device working now with OTA. Country selection worked too. Don't know how, but I just re-flashed another rom (I think it was YT2-1050L_USR_S000066_1410301706_WW21_ROW). My Mobile Data still not working, I'm starting to think it could be a hardware issue.
[Thinkpad Tablet General] :
oops...
[Thinkpad Tablet General] jozeck:
What do you exactly mean by that? I need to restore bios and then flash with KK or just flash KK without restoring bios?
[Thinkpad Tablet General] :
hmm...

i mean exactly what i wrote, if you take an ota and you don't have a country code configured (by using that ####6020# sequence) will cause a brick

if you flash kk stock rom and you did not restored (downgraded) your bios you will also brick, since your bios (still the lollipop x64) cannot load the new bootloader (kitkat uses IA32)
[Thinkpad Tablet General] jozeck:
OK.... tried to restore BIOS. Tool hangs on [PC] Preparing to push files. Tablet was started in DnX mode and after confirming it restarts. Instead of going into fastboot, there is only a black screen.
[Thinkpad Tablet General] :
- make sure you run the tool from the C: drive (for eg from Desktop)

- check that you use the correct one (830-1050 or 1380 depending on your device)

- start in fastboot (droidboot) mode and check what he says under IFWI entry
[Thinkpad Tablet General] jozeck:
Thank you very much for your desire to help

- yes, C:\tmp

- yes, I have 2-1050L, so I used restore-kitkat-bios-830-1050-v2.zip

- IFWI VERSION: (empty)
[Thinkpad Tablet General] :
if the tool hangs on 'preparing to push files' and the same time the tab starts to whatever you had before means you already have the kitkat bios on it. try and flash the kitkat rom and see what happens.
[Thinkpad Tablet General] jozeck:
Worked :) I have working KK. Let's try to OTA to Lollipop - setting country code this time ;)

Thank you again for help :) and will to share your knowledge.

hi@all.....

i have a question about cooking a rom...

I have installed the Core Pro Artemis Kitchen and im able to extract a rom... add packages.. and rebuild the rom... so far so good.

My Question is :

I take a Base rom witch works on my Device (lets say the Official O2 UK WM6 Rom) which has a certain Version Number of the "core" os... (i think its caled Build Number)

There are Roms for other devices which have a higher version Number and i want to "port" this rom to my device..

i tried the following :

1. Extract "Base" rom with Kitchen..

2. Rename C:\core to C:\core-org

3. installed Kitchen again and extracted the "new" rom

4. Rename c:\core to C:\core-new...

5. Rename c:\core-org to c:\core again...

6. Delete the sys folder from c:\core

7. Copy Sys folder from c:\core-new to c:\core

8. Rebuild the Rom

9. Flash the Rom to my device..

after that the Rom boots up and i have the newer version number.

BUT

A lot of Images are "away" (ex. only white background at device setup). GSM is not working and the device crashes after about 5 minutes.

Are there any files that i must keep from the Original Sys folder?

Or must i do the other way? Copy OEM Folder in the Kitchen of the newer Rom?

I no that there will be no complete answer but maybe someone could point me to the right direction...
