The only logical reason is your ADB Drivers are not installed properly or are incorrect and SP Flash Tool doesn't recognize your device...Install the drivers I have attached using the "How to" I have attached too :)
[Android General] underdeveloped user:
Hooooray... it's working again...
[Android General] Camborg80-Trey:
Well, I did it that way (wasn't doing the format option at first before), and still had the same problem.

Can boot into cwm, but cannot boot past first lenovo screen on normal boot.

:(
[Android General] Velial39:
Good afternoon. The huge request to those for whom is available at present full dump stok version A2107A-H Rom 4gb Europe. Share
[Android General] makbro:
It's posted here by Foxtrot_KZ : http://4pda.ru/forum/index.php?showtopic=286687&view=findpost&p=17817202

Download the folder "SP_Flash_Tool_FULL_A2107" and inside it, the "Clear Sky" folder houses the European Stock ROM !!!

If you are looking for the CWM Flashable version, I have posted that here : http://d-h.st/rW4
[Android General] Velial39:
good

I know about it, but for 16gb versions. Me interests for 4 Gb of the version Stock ROM .For SP_Flash_Tool!!!!
[Android General] makbro:
It's flashable on 4GB also...Just open the "MT6575_Android_scatter_emmc.txt" in Notepad++ and changer "FAT ....... " to "__NODL_FAT ....." and u r good to go....That's the only difference in firmwares !!!

Otherwise, I have posted a Stock ROM and complete instructions here : http://xdaforums.com/showpost.php?p=37660076&postcount=890

Also the CWM Flashable version I have posted is for 4GB !!!

I should not FAT a drain without marking veils, I know about a clear sky. And thanks to joint efforts the FOXTROT KZ and my to my tablet is found this way of installation. Once again I will repeat to me 4GB Stock ROM is necessary full dump a drain to make a normal insertion for version 4GB for kickback.
[Android General] manwithmanypiercings:
Let me try to send you an actual CWM backup.
[Android General] makbro:
I have that of my device (created thru Gscript) but the problem is it has my "nvram.img" and "data.img" that contains all my personal info (including passwords)...That's why I haven't uploaded it...

If you can live without "nvram.img" and "data.img", I can give you my device full dump...otherwise, sorry !!!

---------- Post added at 05:59 PM ---------- Previous post was at 05:54 PM ----------

@ manwithmanypiercings, good idea ;)

@ Camborg80-Trey...That is also worth a try ;)
[Android General] Camborg80-Trey:
Welp...

I went on ahead and re-did flashing the f firmware on via makbro's files again.

Still couldn't boot into anything other than CWM.

I had CWM try to restore from the zip you pm'd me (Extracted it to the restore folder, it was seen just fine by cwm).

When I tried to run the restore, I get this message:

Checking MD5 sums...

Erasing boot before restore...

Restoring boot image...

Restoring system...

Error while restoring /system!

And nothing happens after that.

I appreciate everything guys but I'm inches away from just giving up already. 2 hours of sleep and I'm not one step closer than I was when the device was originally bricked :(
[Android General] manwithmanypiercings:
Sorry, Wish there was something else I could do.
[Android General] makbro:
Bad luck really :(

Since you have another back-up now, try doing this...Replace the "boot.img" and "system.img" in the Stock ROM folder (named A2107A-F_S484_121211) with the "boot.img" and "system.ext4.tar" that is there in manwithmanypiercing's CWM back-up and flash device with this using SP Flash Tool !!!
[Android General] Camborg80-Trey:
Ill give it a shot after work tonight. If that doesn't work I'm left with having to buy another f model and try that backup method...

Got any instructions for that makbro? I'm gonna try it monday night if this method doesn't work. And that ends up not working then.... :(
[Android General] makbro:
I missed your post earlier somehow...Here is the step by step procedure to root your device :-

1. Download and extract the "USB VCOM Drivers" from here : http://xdaforums.com/attachment.php?attachmentid=1717500&d=1360494240

2. Download the "How to install ADB Drivers.doc" here : http://xdaforums.com/attachment.php?attachmentid=1717501&d=1360494240 and read it carefully...It will guide you how to install the drivers downloaded in step 1...

3. Install the drivers as per procedure described in the document in step 2...

4. Download and extract the archive "4.03root.zip" from here : http://xdaforums.com/attachment.php?attachmentid=1486413&d=1353075835

5. Now turn on your device, let it boot completely, then run the batch file named "root.bat" in the folder that you extracted in previous step 4...It will start rooting your device...Now this is probably tricky and most important, Your device will restart 3 times before it's completely rooted, each time the batch script tells you to "press any key to continue" you have to wait until the device restarts completely, then press any key...

6. After the third reboot, the batch script will tell you rooting is complete, and it will be ;)
[Android General] manwithmanypiercings:
I have one.. heat up the seals on the box and switch your crap out lol j/k

I tried other usb port but same problem
[Android General] pemergency:
It looks as both of you guys doing wrong same thing.

One more time.

1. Start SP_Flash_Tool_v3.1206.01

2. Press Scatter-loading and choose MT6575_Android_scatter_emmc.txt from CWM Firmware folder

3. Press Format and tick Auto format Nand flash/format whole flash.

4. Press OK!

5. NOW Connect your device and press reset button on a back of your device.

Program should format your device and dispaly OK in a green circle. If this will not work it looks as you have a problem with a drivers.

If you will se OK in a green circle you will have no problem with recognize your device under SP_MDT_src_v3.1216.02_A2012.05.22

Than follow procedure from manual from a point 1. of (Installing CWM Recovery ROM)

Good luck

Is there way to get the orgenal rom back or to reset the device so it can start again?

Thanks
[Android General] drtemz:
Hello everyone

i just need CWM with my current stock rom ( so i can backup it first then start playing:D )

thanks
[Android General] pemergency:
NO not yet

---------- Post added at 06:44 PM ---------- Previous post was at 06:42 PM ----------

Yes if you find original ROM, I have a original ROM chinesse if you want...

Tell me somethink, did you try to format your device? without flashing afterwards?
[Android General] hasan2013:
But the computer does not recognize the device and it shows that unknown device. However the next process for installing the frimware u didnt mantion what file should choose? Maybe if i do this process the device will start
[Android General] pemergency:
If the computer not recognize device this is meen as you have a problem with drivers install whole ADB SDK package. On which point I didnt mension what file should you choose?
[Android General] hasan2013:
No i didnt i just followed ur process. How can i install the orgenal rom?
[Android General] pemergency:
Im not getting you? how did you brick your device without drivers? this is not make sense...

Thanks alot
[Android General] makbro:
Will post the instructions for you tomorrow morning :)

Wouldn't hurt, it's better to do it ;)
[Android General] patenteapoil:
Thanks for the reply, but I have a bit of a problem...I tried following the instructions on the doc but at step 2 when it should detect the device "Lenovo preloader", I get "MT65xxx preloader" is that a problem or does it not matter?

EDIT

In fact it is a problem, if I try to continue after, while running root.bat, after the first full reboot it fails to chmod superuser.apk and pretty much everything else, the tablet reboots and root.bat closes with no result
[Android General] Velial39:
OK. Provided that it 4gb version stock ROM. Lay out on any file hosting service. I thank.
[Android General] degsie:
If you are trying to root then you should have an entry in the device manager for "ADB Interface". Have you enabled USB debugging on your device and re-connected without holding the reset button? If you dont see "ADB interface" from the device manager then drivers are not installed properly and will fail to root using the batch file...
[Android General] tikkesang:
While doing your works, take a look @ Ubuntu Phone. I think it is an innovation on phones UI

http://www.ubuntu.com/devices/phone

You can use youtube for more videos

Good Luck with that ;)
[Android General] makbro:
It is not a problem...The main thing is the PC should detect the Preloader and you should manually install drivers for it...Just check whether you have USB Debugging enabled under "Settings"---> "Developer Options"...

The other way of installing ADB (if you don't want to do any further modding) is to just install the software "PDA.net" on your PC (with device connected and USB Debugging Enabled in "Settings"--->"Developer Options") and select "Unknown Device" or "Not sure" option (since it doesn't have Lenovo brand supported, don't worry, ADB Interface will still be installed)...After that run root.bat !!!
[Android General] makbro:
Instructions to create full ROM dump from a New Device

Here are your instructions, please read carefully...

0. Don't install any update on Stock ROM...Enable USB Debugging on your device from "Settings"--->"Developer Options"...

1. Download and extract the "USB VCOM Drivers" from here : http://xdaforums.com/atta...0&d=1360494240

2. Download the "How to install ADB Drivers.doc" here : http://xdaforums.com/atta...1&d=1360494240 and read it carefully...It will guide you how to install the drivers downloaded in step 1...

3. Install the drivers as per procedure described in the document in step 2...

4. Download and extract the archive "4.03root.zip" from here : http://xdaforums.com/atta...3&d=1353075835

5. Now turn on your device, let it boot completely, then run the batch file named "root.bat" in the folder that you extracted in previous step 4...It will start rooting your device...Now this is probably tricky and most important, Your device will restart 3 times before it's completely rooted, each time the batch script tells you to "press any key to continue" you have to wait until the device restarts completely, then press any key...

6. After the third reboot, the batch script will tell you rooting is complete...

7. Download and extract "Gscript Lite" attached with this post, copy the "gscript" folder to the root of your sdcard (internal)...Now install "GScriptLite.apk" and run it, needs root access, grant it...

8. In the app hit the menu button and pick "Add Script" --->"Need SU?" must be checked ---> "Load file" ---> select "back_mt6575_a4_v2d.sh"...

9. Go to "Settings"--->"Display" and set dim display timeout to at least "30 minutes"...

10. Now run the app "Gscript Lite", click on the script you loaded named "back_mt6575_a4_v2d.sh" and wait for about 10 minutes while it creates a full dump of your ROM at "/mnt/sdcard2/back-up v2" folder (that is your external sdcard)...

11. For a second full ROM dump, run the software "MTK Droid Tools" on PC with device fully booted and connected to PC--->select tab "root, backup, recovery" and check the box "Backup userdata and cache"--->click "Backup"...Now Droid Tools will make a full back-up of your ROM and save it in the folder "backups" inside the main folder of MTK Droid Tools...

12. These two back-ups will have all the files required to flash the ROM of new device to any device using SP Flash Tools...These are :-

PRELOADER (.img or bin)

DSP_BL (.img or no-extension)

MBR (.img or no-extension)

EBR1 (.img or no-extension)

UBOOT (.img or bin)

BOOT (.img)

RECOVERY (.img)

SEC_RO (.img)

LOGO (.img or bin)

EBR2 (.img or no-extension)

ANDROID (.img)

CACHE (.img)

USRDATA or DATA (.img)

FIRMWARE.INFO

13. Download and extract "MTK ROM Studio" also attached with this post...Run its .exe on PC, open the file "Firmware.info" generated by "Gscript Lite" back-up and click "File"--->"Save Scatter" to generate "MT6575_Android_scatter_emmc.txt" automatically...

14. Now you are good to go ;)
[Android General] makbro:
It is from my device that is 4GB and it is the Stock ROM full dump...

The ROM is rooted and with CWM, since you cannot create a full dump without rooting it...

It doesn't contain "fat.img" since neither "Gscript Lite" nor "MTK Droid Tools" creates that image and when I made it, I didn't know how to "read-back" data from device so I didn't create it manually either, afterwards I had installed custom ROM...

I'll PM you the link !!!
[Android General] makbro:
Check under "Settings" whether you have "Vibrate on touch" selected (I think it's either in "Sound"--->"General" OR "Accessibility)...If it is selected, un-checking it should solve the vibrating issue...

For the audio, run "Mobile Uncle Tools" app, click on "Engineer Mode MTK"--->"Audio", select "Media" under second option and play with the "Max Vol" value...It is between 0 and 160, set the value that reduces the sound issue...Do the same with "Speakers" or "sph" option as well (select "Speakers" or "sph" in place of "Media" as you did above)...

In fact from here, you can set all sound related values including mic, speakers for headset mode or media mode, just adjust "Max Vol" field :)
[Android General] Velial39:
It turns out at you full dump custom 4gb versions. Without marking veils. Such and I now can make. But Rom.Takaya is necessary to me from veils a marking full dump stock 4gb as at you doesn't approach.

---------- Post added at 02:51 PM ---------- Previous post was at 02:45 PM ----------

FAT surely has to be present in full to dump, without it there is no sense.
[Android General] makbro:
You obviously didn't understand what I said...All the main files including "boot.img, recovery.img, system.img and secro.img" are from the Stock ROM...All the other files of my full Stock ROM dump that I replaced with Chinese Stock ones are also included in a separate folder in the archive and that completes the STOCK ROM Dump (except "fat.img"), NOT CUSTOM ROM...So I'm not lying when I say this is the Stock ROM dump !!!

Regarding "fat.img", I guess I am senseless (as you implied) and don't understand why it's the part of the most important part of ROM :)
[Android General] Camborg80-Trey:
I did that but I still have the same problem (CURSES!)

Basically, it's like when I play sound locally or on the internet - I won't hear any come up, but I will hear a random "pop" noise coming from the speakers in the tablet. Sometimes it repeats intermittently, sometimes it doen't. In some instances volume does work on the tablet for about 4 seconds.

Strangely though, I turned the sound on for clicking stuff and that work just fine everyiime.

SOOO CLOSE MAKBRO! Please, if I can get the sound on this thing to work reliably then I'd probably jump through the roof in happiness. I might've been able (with you primarily helping me) get Lewa onto my tablet, different firmware and all!
[Android General] makbro:
Check "Settings"--->"Accessibility"--->"Talkback"....If it is ON, turn it OFF :)

To get "Talkback" running, install the app "Ivona Text to Speech HQ" and then download any voice files "Ivona Amy GB" or any other (also thru playstore)...Then go to "Settings"--->"Language and Input"--->"Text To Speech Output" and select "Ivona Text to speecch" as the default tts engine...Then you can turn ON Talkback again !!!

NVRAM Error

Hello,

thanks for this ROM and yout work. :good:

I've testing this ROM, the most is working very good. :o

But i have a big problem about the WiFi: :(

there was a WiFi-Ghost ==> NVRAM WARNING: Err = 0x10 (00:00:00:00:00:00)

and the WiFi-MAC-Adress is changing on a boot! :eek:

I've change back to Stock-Rom, but i have the same Problem! :rolleyes:

Have someone an idea to Repair this? Thanx for help :confused:
[Android General] manwithmanypiercings:
Glad you finally got it up and running. Did your contacts or people app show up with that ROM?
[Android General] makbro:
It's because you didn't replace the folder "/data/nvram" with the one from your back-up as I posted in instructions...

If you have this folder from your back-up (before installing any custom ROM), just delete the folder "/data/nvram" from the device and copy this folder from your back-up at the same location...Then reboot device !!!
[Android General] Velial39:
OK. Whenever possible lay out yours dump on a file hosting. Probably because of my bad English, I that did not understand that. After viewing dump it will be visible, will be suitable or not it for insertion preparation for kickback. It is very grateful for your participation.
[Android General] greeneye:
Hello makbro,

thank you very much for your answer :)

I test it now and restore the "/data/nvram" from my backup

and have the same problem.

Now I find an Error in my Backup

[this is not completed and have read-error],

ahhh sh*t!!!

Have you an Idea to repair?
[Android General] dirtrider146:
@Camborg80-Trey, Im having the same problem that I can't boot past the first "Lenovo" Screen and can get into CWM. I read your post on how you final got past that, Congrats, I have been working for hours to get to that point "My fiance thanks I am crazy because I keep working and working with no positive results" Though she thanks I should just be able to press a button and everything just work lol. After reading your post, the only problem is I'm lost with all the links and can't find the thing you said that got it to work. Anyway you can help me out with that?
[Android General] makbro:
You are welcome...I have attached the "fac.img" with this post...

"pmt" folder just includes the multimedia files like "Music, Photos, Emoticons" etc and "fac" includes some apps downloaded and installed during the OTA update so both these are not important at all since the ROM flashes and works completely fine without these ;)
[Android General] Camborg80-Trey:
And try to help someone else through this nightmare? Hell frickin' yes! :)

First off, what is the model of your device, and how big is the internal sd card on it?

I'm assuming it's the a2107a-f model, but I just wanted to make sure.
[Android General] makbro:
You can restore your IMEIs using the "replace IMEIs" option in "MTK Droid Tools" (Download from here : http://mediafire.com/?b0pdv2e4q1uj9ia)

EDIT : About the MAC address, you can do the following :-

To restore MAC Address, enable WiFi...open "Terminal" and type the following commands :-

su

busybox iplink set wlan0 XX:XX:XX:XX:XX:XX

(Just to be totally unambiguous, you have to replace XXs with your actual MAC Address)

For the rest, you must have all the files from back-up to replace and correct that !!! In fact all the device info is restored only if you replace the complete "/data/nvram" folder from back-up...If you use someone else's, you will be using their device info !!!

---------- Post added at 08:13 PM ---------- Previous post was at 08:11 PM ----------

Hi Camborg80-Trey, did turning-off "Talkback" remove the sound issue or was it never ON in the first place ???
[Android General] Camborg80-Trey:
Well, I did all that and it didn't have any effect...

Went to go play a sound file and i only heard the first 4 seconds of it before the sound completely stopped working, but not before a small "pop" was heard. I know it's not the device itself - works on boot and clicking stuff. It's because I'm trying to run this badass mod on an F model, lol.

Still, I wish there was a way to fix this one thing! I'm so close! :P
[Android General] dirtrider146:
Yes its a F2107a-f, 8 Gig model
[Android General] manwithmanypiercings:
Have you tried going through all of your sound profiles?
[Android General] degsie:
So some ppl are managing to load custom roms onto the A-F model? I'm all ears!!!

Which roms load sucessfully? I understand that one poster has some audio issues after loading a rom.

I have a A2107A-F model, 8GB. I am rooted and have CWM installed.
[Android General] Camborg80-Trey:
I found that it was not turned on. Also adjusted all the volume settings in the media categorgories to 70. Still no change.

Also there is a three second delay between every third key press on the keyboard which makes tyipig jerky impossible as yo can see from his post LOL.

This might be a lost cause guys :(
[Android General] makbro:
Can you send me his CWM back-up, let me prepare the .img files from it so that you can try and flash them thru Flash Tool !!! (May be manwithmanypiercing's "/system" can work for you)
