It's ok makbro. If I can't get the audio and keyboard delay issues resolved on the tablet I'm just going to chop it up as a lost cause and pull the switcheroo method. I can mess with my tablet while at work but I just have a sneaky suspicion that there won't be much I can do as it might just be firmware and hardware specific.

Any other tips for the tablet issue? I it'd be a great to get it to work. I might open a whole new Avenue for us f model guys :)

Also assuming I do get another f model working, are there any tweaks or safe mods I can use on it? I I have read about tweaks possible for the first model in this thread but have lost what pages they're on.

P. S. I I'm typing this post from my synergy-molded s3 with SwiftKey 3 and it is amazing. I would kill a man to get this kind of responsiveness for my position tablet lol!
[Android General] dirtrider146:
Looking at the other post, I would say yes. I wasn't actually trying to run a different ROM LOL, I was trying to fix the Bluetooth profile, and deleted the wrong JAR file, I couldn't get to the point that I could copy the file back on to it. The process lead me to following the rom install options and now I'm stuck at the 1st Lenovo screen like Camborg80-Trey was. So I'm hoping to get it to boot again. Sound issues can wait. I mainly care about finishing the book I was reading on it.
[Android General] Camborg80-Trey:
UPDATE: I have found that the tablet also does not recognize having more than 26 percent charge, and no matter how long it's plugged in.

Sorry fellow f model owners... We might be sol on installing lewa on this device unless makbro or others could figure this out. I have no idea.
[Android General] makbro:
OK, as you like !!! (Although I have come across another -F ROM dump)...

As for any other tips to recover from sound issue, none for now !!!

Safe tweak for performance boost is "V6 Super charger"...Download from here : http://xdaforums.com/showpost.php?p=18703418&postcount=5021

[Android General] Camborg80-Trey:
Another f rom dump eh? I I'm down to try one more time tonight if you think it might work. I at this point I'm getting a tad versed at all this lol :)
[Android General] Herrthegeek:
Just wanted to let you know I am in the same boot....an A2107a-f device...with the only bootable ROM being the -h variant, which is causing a large amount of issues. Thought I would let you know you are not alone...and will let you know if I find a fix.

modem.img

makbro,

Over the threads I noticed a few ROMs built with various modem.img to check the functionality of 3G. I assume it would be helpful for all of us if in a single post you could put different modem.img files with you that are compatible with our device possibly with a mention of the source where they were obtained from. That would allow us to take it one by one into the kitchen and find out whether it works or not? Right now I haven't gotten the opportunity to test LEWA ROM I am on. But I soon intend to and don't realistically expect it would work off-hand. It would be tremendous support if everything that is already known to be working or otherwise is available.

Thank you eternally :)
[Android General] makbro:
I can't promise anything 100% (due to not having the device) but I am pretty sure I have obtained the correct, fully flashable and working ROM dump of Stock A2107A-F model :)

In the mean time, I also checked the "system.img" obtained from garringm's and D's back-up using ext4_utils and discovered what was wrong with them (hence your device not booting when they were flashed)...

I am checking this new "system.img" and found no similar errors...If all is well, I'll upload the ROM tonight and would be accessible to you by morning ;)
[Android General] manwithmanypiercings:
I hope you can get it to work for them. I have no idea why mine wouldn't work since it was literally just my CWM recovery lol.
[Android General] makbro:
:) There was no issue with your CWM Back-up...since -H firmware has been installed, they need to use Flash Tool to format whole NAND Flash and install a SP Flash Tool version of the ROM (that should be working)...

Once they get back to -F firmware, they can very well flash your CWM Back-up without any problem ;)

Keep-up the support, thank-you :)
[Android General] makbro:
It's good that you brought this up...I have recently established that replacing "modem.img" DOES NOT require changing the ROM completely or cooking/ flashing new ROM...So I am posting the procedure to correctly replace "modem.img" in any compatible installed firmware (If you follow the procedure ending up as "Baseband Unknown" means modem is NOT compatible)...

Please note that none of these "modem.img" files are mine, they are from different ROMs posted on different forums including bbs.lenovomobile.com (chinese) or 4PDA (Russian)...If you download and extract the archives, I have named the folders after the ROM from which the file has been extracted :)

Use Root Explorer to perform all these steps :-

1. Place the new "modem.img" you wish to use in the root of your external sdcard (or a folder at root of external sdcard, you can keep all the ones you want to try in different folders as well)...

2. Now Copy the new "modem.img" from "/mnt/sdcard2/..." (...where you put it) and browse to "/system/etc/firmware" folder and Paste the new "modem.img"...Remember, don't delete the previous one, overwrite it when prompted by pop-up...Don't exit the folder yet, go to next step...

3. Change the properties of the new "modem.img" file just replaced and set them as shown here :-

4. Reboot device...Your modem has been successfully replaced...If you find "Baseband Unknown" under "Settings"--->"About tablet/ phone" this means the new modem.img is incompatible with this ROM, just replace it with another ;)
[Android General] Herrthegeek:
I just wanted to say thanks!! This would be flippin awesome if it works...I have pulled my hair out for the last 48hrs, too the point that I was about to go buy another unit so I could build a clean SP Flash for others. Thanks again!
[Android General] dirtrider146:
I am sure grateful for it as well. Glad to see I'm not the only one with the problems.
[Android General] Camborg80-Trey:
I'll hold off until I try this as well makbro...

One more shot! Maybe this is the one! Who knows...after all this nightmare I've gone through maybe I'll learn a bit and somehow convert LeWa for the F model and remove the useless stuff like contacts and phone call options?

Lol, I kid. But this sounds promising makbro please keep us informed!!!
[Android General] makbro:
Yup, testing is finished and I am quite confident this ROM will work (if only I had access to a -F device, I could check it to be 100% sure)...I am uploading it right now but it'll take a while ;)
[Android General] Al3xxxinho:
Hello boys and girls

I have a a Vodafone Smart Tab 2 7.0 ( 4gb internal memory and 1gb ram, single sim slot ) and I am facing some difficulties.

Does anyone know where can I get the official vodafone rom ?

Now I have Clearsky rom but my memory readings are incorrect.

Also is there any way to get wifi mac address back without having data/nvram backed up ?

Thank you for your time
[Android General] makbro:
Sorry, don't have vodafone ROM but I have solution to both problems :)

To correct memory readings, copy all the contents of "/mnt/sdcard" to external sdcard or PC...Then go to "Settings"--->"Storage"--->"Erase USB Strorage" and select "OK" to format the internal sdcard...After format, reboot device and copy the contents back !!!

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 and must have busybox installed) :)
[Android General] dirtrider146:
I am willing to let you barrow mine to test with LOL just don't know how to get it to you. LOL
[Android General] Al3xxxinho:
makbro thank you for your time.

Wiping the sdcard fixes the internal memory problems.

Still the wifi mac problem is unresolved.

I go to settings - about tablet - status and I see the wlan mac adress.

I open up terminal emulator type busybox iplink set wlan0 and the mac I got from the settings menu but it gives me this: either "dev" is duplicate or ( the mac adress i wrote earlier ) is garbage.

Also, is there a way to replace the generic serial number and dissable the second sim menu ( my tablet has only one sim slot ).

Thank you!

A2107A-F Flash Tool Stock ROM

Here it is guys, the stock ROM for A2107A-F to be flashed thru SP Flash Tool v3.1216.02 :

EDIT : ROM taken off, did not work as per feedback :(

1. Run the Flash tool, choose "MT6575_Android_scatter_emmc.txt" from the extracted ROM folder...

2. Check, whether all image files are selected to be flashed...If not select manually...

3. Click "Format"--->"Auto Format Whole NAND Flash"--->"OK"...Keep the reset button of the device pressed while plugging-in the USB cable and release once cable is plugged in...Wait until Format finishes with "Format OK" message in a big green circle pop-up...Disconnect device...

4. After format, check "DA/DL All with checksum" and click "Download"...Again keep the reset button of the device pressed while plugging-in the USB cable and release once cable is plugged in...Downloading would begin and wait till it finishes with "Download OK" message in a big green circle pop-up...

5. And the moment of truth...power-on device :fingers-crossed:

I will see the thread tomorrow morning (EEST), hoping with some good news ;)

---------- Post added at 12:20 AM ---------- Previous post was at 12:14 AM ----------

For MAC Address, enable WiFi, type the command "SU" then "netcfg" to see what all interfaces are there initialized as "wlan..", Use the interface number (0 or 1 or what ever you see above) in the command "busybox iplink set wlan.. XX:XX:XX:XX:XX:XX"

Regarding single SIM menu, not possible in stock ROM...If you install Chinese modded ROM or Tesmart modded ROM that I have posted, each has only one SIM menu in "Settings"...
[Android General] Al3xxxinho:
Still getting the same error.
[Android General] makbro:
Why are you using the same MAC Address that is already set ??? I mean you are noting the MAC address from "Settings" (that is already set) and trying to set the same again !!! That's why you are getting the "DUPLICATE" error :)

What you need to do is set the original MAC address instead of using the one that is already there ;)
[Android General] Camborg80-Trey:
Testing now...KEEP THOSE FINGERS CROSSED!
[Android General] Al3xxxinho:
The problem is that I don't have the original MAC adress ... If it was printed on the box, i'm sorry to say but i threw it away from day 1.

Do you know where else I can find it ?

Thank you.
[Android General] makbro:
Really sorry about that...Right now, you can try to flash a stock ROM using SP Flash Tool, I have posted one here : http://xdaforums.com/showpost.php?p=37570061&postcount=868 ... that would get rid of this changing MAC address issue...

Before you flash the ROM :-

1. Note down your IMEI numbers for restoration after flashing...

2. Remember to change the FAT value inside the "MT6575_Android_scatter_emmc.txt" from "FAT 0x924e4000" to "__NODL_FAT 0x924e4000" in case your device is 4GB or 8GB because the "fat.img" in it is for 16GB

After flashing the ROM, you can restore your IMEIs using "MTK Droid Tools"...
[Android General] Camborg80-Trey:
Well, I did the process to the T (used the proper SP Flash tool, checked FAC, etc.) after formatting. The entire process took 10 min. 43 seconds (a new record for my flashing experiences).

I thought this was it. But, upon booting up...

Still stuck on Lenovo screen (first one).

Interestingly, I CAN however boot into the STOCK Android recovery. For kicks, I did the wipe factory/data restore and cache settings and rebooted.

Still would not advance past first lenovo screen.

Sorry guys, this looks like an all-hope-lost cause (unless Makbro, the TABLET GOD (Thanks for all your effort regardless sincerely), can come up with something.

I plan on doing a little "swap" with walmart. If I succeed I will consult makbro on how to upload all the important files for sp flash so anyone else suffering through this can recover their device.

If anyone else has any other ideas, please chime in.
[Android General] makbro:
OK, can you now flash the CWM Recovery from "recovery.img" that I posted here : http://xdaforums.com/showpost.php?p=37743903&postcount=926 ... and try to "Restore" the "manwithmanypiercing's" CWM back-up ???
[Android General] Camborg80-Trey:
Pretty sure I'd need mobileuncle for that, don't I? And since I can't even boot past first lenovo screen, not sure how I'd do that.
[Android General] makbro:
Use the UPDATE 3 procedure of csns post here : http://xdaforums.com/showthread.php?t=2044496 but replace the "recovery-----.img" files that are there in it's extracted folder with my posted "recovery.img" file...The procedure uses Flash Tool, so you don't even need to boot the device, just keep it with the -F firmware, whichever state it is in right now with this new ROM :)

Better even use the Flash Tool that I suggested so that the flashing procedure doesnot change (his is an older version and flashing procedure is different), just use his folder and Flash Tool v3.1216.02 :)

EDIT : Next I am going to cook a .zip CWM Flashable from this new -F back-up, will post tomorrow, not going to leave any stone unturned ;)
[Android General] Camborg80-Trey:
No dice. I moved your flash tool folder over to the A2107A-easy_CWM folder (from step 3 on that link) and ran it. I had it load the scatter file that was in A2107A-easy_CWM, and also use the preloader file that was included as well, but I redirected it to use D's recovery.img.

After pressing download, I get this:
[Android General] makbro:
Try using his Flash Tool, the difference in flashing is that device has to be connected when you select the scatter file, then press reset button once, flashing will start, then press reset button again after flashing...Then you can boot into CWM :)
[Android General] makbro:
If the "CWM Restore" option with manwithmanypiercing's back-up fails too, try replacing the scatter file in the new SP Flash Tool ROM that I posted today with the attached one and flash again, this time "fac" will not be flashed !!!
[Android General] Herrthegeek:
I got same result as far as stuck at the first Lenovo screen....BUT I finally succeeded in loading CWR. I had to change the process a little though for it to take.

It kept complaining that I need to download ALL files..and refused to continue. So I took Makbro's stock scatter file....but swapped the preloader, and recovery images from the files we just downloaded in the last step...and BANG!!! I got CWR.

Now to see if I can restore a backup???

UPDATE: Install from sdcard appeared to succeed, but even after performing all wipes...I am stuck in a reboot loop. At least I am one step further.
[Android General] Herrthegeek:
Maybe my eyes are crossed...but I cannot seem to find the link to manwithmanypiercing's backup? Any chance a guy can get link. I tried to restore the A2107a-f rom you had on dev-host (A2107A-F_S484_121211.zip) but that rom has lead to my reboot loop?
[Android General] makbro:
It may sound weird but "bootloop" is good news as compared to being stuck on first Lenovo Logo...Just hold on a bit longer guys, I'll post two ROMs shortly, one for SP Flash Tool (again) and second for those who have managed to flash CWM successfully...

And about manwithmanypiercing's CWM back-up, he sent the link to Camborg80-Trey via PM, not posted on thread !!!
[Android General] makbro:
-F ROMs....AGAIN !!!

Yet another try at getting the A2107A-F working again...

EDIT : Attempts failed again as per feedback from Herrthegeek :(

makbro help meee
[Android General] brickedstone:
This is what I and probably many others faced when tried to install another ROM via CWM. I don't know the technical glitch causing it, but the workaround is simply to first flash into your tablet a stock or chinese, whatever you wish, using SP flash tool. It will completely replace everything including that which is making your device stupid enough to work together with custom ROMs. Then install CWM and it would be good to install any of the modded ROMs posted here.

Wish you all the best

You are welcome, now you can flash CWM Recovery and install any of the other modded ROMs I have posted, If you like ;)
[Android General] Camborg80-Trey:
Even though another user reported that it didn't seem to work via sp flash tools (unless I'm mistaken), I will still give this sp flash tool a go. In the meantime makbro, I will pm you manwithpiercings' backup and you can edit out the "sensitive" bits of his data (said email was included in it or something and ask that I delete it.

You'll also see the lack of his .tar for the system file (when you origninally asked me to use it). I just PM it to you and we'll see if it does anything! Here we go... :)
[Android General] Camborg80-Trey:
EDIT: I'm a total newb and can't figure out how to send files via PM, lol.

Here is the file (I doubt any of us newbs can do anything with it anyway):
[Android General] Camborg80-Trey:
Alright, so here's how it went!

Flashing took about 9 min. 30 seconds. Wasn't getting past first lenovo boot logo. Went on ahead and flashed D's recovery.img file (the first one you uploaded) by using SP_Flash_Tool_v3.1224.01 (this was the ONLY version I could use in order to work. I think it also happens to be the latest one).

Good news! Flashed successfully and I had CWM on the tablet. I tried to run manwithpiercings's backup but kept getting an "Error: installation aborted." message. Just for kicks, I wiped user date/cache and dalvik cache several times then tried installing update from sd card using the F-firmware stock rom.

It staid it installed successfully (as it always did for me), but now after reboot it will go to the first lenovo screen, stay there for 4 seconds...THEN REBOOT! I have NEVER seen this before and in my mind might be a sign that we're on to something!

Like my theory went, I suspected the F-rom via CWM never worked because I had H-FIRMWARE on the tablet at the time. Now since we have F-Firmware, perhaps the tablet really is trying to get it to work or something.

It's still mystery to me, but it feels like we're very VERY close...
[Android General] makbro:
manwithmanypiercing's back-up is from the new CWM format and is incomplete without the "blob" files (also made by CWM)...This is compatible with CWM 6.0.1.5...That is why you face errors while trying to restore this back-up, you can never do that without the "blob" files...You can read all about this in the words of CWM developer himself here : https://plus.google.com/103583939320326217147/posts/L5aVZe7C9vg

I am just uploading another try at the CWM flashable .zip...Because of the bootloop now, I feel with more assurance that the device can be fixed!!!
[Android General] manwithmanypiercings:
Well hell.. I can send him the blob files lol. Didn't realize those had to be in there.
[Android General] makbro:
If you could send them to me too, I'd very much like to build a working CWM Flashable Stock ROM for all the -F troubled members...Thanks
[Android General] manwithmanypiercings:
will... i'm zipping a copy of the folder right now so I can upload it to Drive.
[Android General] makbro:
And it would be a great favor for all the -F device holders if you could upload full ROM dumps (using Gscript Lite AND MTKDroidTools) as well so that they can flash them thru SP Flash Tool...

I am asking you for help since I myself have a -H model, so basically I am trying to get the only ROM Dump (By garringm) to work for them in the SP Flash Tool blindly (implying without the device ;) )
