Here's the thing Makbro - I can return the device, opened, to the my local Best Buy and get a full refund! So I'm not really spending a penny! If you could give me step-by-step and a list of needed tools at your convenience I'd really appreciate it - whatever I need to do to get that firmware off the new f-model, and USE SP FLASH to put it on my crippled one right now :)

Now, in regards to the CWM method...

The big problem with that is that I can only get the H model firmware to actually boot my F model device. I can root the device after I put the H firmware on (remember, trying to get the F firmware because this one is buggy and glitchy because of different model!), but I can't install cwm recovery. Or, more specifically, I can never find where to delete the file that restores stock recovery (mobileuncle flashes successfully but stock recovery always comes back) is. I read earlier in the thread that you have to navigate to /system or something (how I have no idea, I can only see internal and external sd cards on the tablet when I look via Windows XP). and delete a file, but I don't know how to navigate there).

Do you have any advice? If I can find and delete that file, here's what I'm thinking I could do:

1) Mount H model firmware on MY F model (to get it to fully boot at least).

2) Root

3) gspbackup thing.

4) make recovery file

5) Use mobileuncle.

WIth cwm installed, you think I could flash that F-model firmware onto the tablet, even though it has H firmware (that I will install as mentioned earlier)? If I could, I will try this when I get off work and we might be in business!

As always, THANK YOU
[Android General] makbro:
I have read your mail in detail...There is a very simple solution to prevent you from all this :-

1. I have the boot.img of the -F model, so I can prepare a "recovery.img" that will flash CWM Recovery successfully to your device...Just flash recovery and don't power-on or boot device !!!

2. You need to place the A2107A-F stock ROM from my post to the root of your external sdcard (just take it out of the device, use minisd adapter and save the zip file in the external sd thru PC)...

3. Then what you do is power-on straight in to CWM Recovery, perform all 3 wipes (data/ factory reset, cache and dalvik cache) and install the stock ROM as "Install zip from sdcard"...

That should do the trick ;)

The reason that I am trying to get you to do all this is even if you buy a new device and use it to restore this one, it would require to be rooted... That itself voids the warranty...I don't know any procedure thru which traces of rooting can be removed completely except the SP Flash Tool Flashing of a Factory Stock ROM, that we don't have and cannot have, so you would not be able to get a refund for any of the devices !!!
[Android General] manwithmanypiercings:
Best buy won't check for root when he returns the device. They'll just sell the item as an open item "as is".

Can you post the image for CWM with the -f? Mine isn't working for some reason. I keep getting an error message when trying to do it and i've moved the michfood folder completely to the root of C drive on my computer.
[Android General] makbro:
OK, then...It's up to Camborg80-Trey to decide if that's the case...The solution that I offered is much more simple don't you think :)

I have attached the recovery.img for A2107A-F with CWM 6.0.1.5...Please let me know if it works !!!

Could you also post your original "Recovery.img" so that I can re-check this recovery I made from "michfood" ???

EDIT : And regarding the error, you should re-name the file "cwmr 6015.bat" to "cwmr6015.bat" (remove the space in between) and you are good to go !!!
[Android General] makbro:
CWM Recovery 6.0.1.5 for A2107A-F

Attached are the two "recovery.img" files that I have for the A2107A-F model with CWM Recovery 6.0.1.5, first one is from D1358531 and the other (zipped) I prepared from the stock recovery.img from garringm back-up :)
[Android General] manwithmanypiercings:
I'll try and get it to you when I get home. I don't have my tablet or my laptop with me right now. Thank you very much for that file though :).
[Android General] makbro:
You are welcome and I hope it works :)
[Android General] brickedstone:
makbro,

I tried flashing the latest Lewa ROM you shared. After doing all the wipes, I chose the option of install zip from sdcard and then rebooted. But ever since my tablet is booting into CWM. Any idea what might have gone wrong? Of course the device is fine, I quickly reverted back to a backup. But I cannot rest until I get the modded stuff running :)
[Android General] Camborg80-Trey:
Thank you makbro...I will try and give it one more shot! Only question I have is, can you identify what file I'd have to delete in order to prevent the STOCK recovery from setting itself back up after I use mobileuncle (this happened to me last time)? I believe its a file in the /system folder of the tablet, I'm just not sure which one or how to even navigate to it (can only browse Internal and external cards when I connect th3 tablet to my pc).

Also, which of the two recovery images you uploaded should I use in my current situation? Many thanks!

Also, which of the two recovery images you uploaded should I use in my current situation? Many thanks!

EDIT: Actually, wouldn't I need the recovery.img for the h model and NOT the f model? Reason I ask is because the firmware ill be running just to get it to boot is the h's (even though I have the f model. Its the only way I can get the device to fully boot).

Way I see it unless I'm wrong, I'd wanna reflash my tablet with the h firmware, install mobileuncle, and then run the recovery.img for the h model, right (since my tablet will think its an h model when it really isn't).

Or do you think running the f model recovery.img should still work just fine?
[Android General] makbro:
It's not the matter of tablet thinking it's -h ... It is -f and will remain that ... The reason it's working with the -h firmware is that they are quite similar ... Yet they are slightly different (including no 3G) so your device is glitching badly ...

You definitely need to install recovery.img for -f using Flash Tool, not Mobile Uncle Tools ... Just get the device into power-on state with any firmware, flash one of the "recovery.img" I have attached in my last post and try to boot directly into recovery ... If that doesn't work, use the second "recovery.img" I posted ... One of two will definitely work :)

Once you get into CWM Recovery, Installing my cooked Stock ROM for the -F would be easy (after wipes of course) ;)
[Android General] makbro:
I guess our timings would not match today as well, so here's what you need to do step by step :-

1. Download the A2107A-F Stock ROM I posted here : http://d-h.st/rW4 and save it to the external sdcard of your device (using sd adapter and laptop/pc if you can't access the card in the device)...After copy, put the sdcard back in device...

2. Download and extract this package to your PC : http://www.mediafire.com/download.php?fbuzi5xjofs7vgf

3. Download the two "recovery.img" files I posted here : http://xdaforums.com/attachment.php?attachmentid=1712957&d=1360338271 and here : http://xdaforums.com/attachment.php?attachmentid=1712964&d=1360338404

4. Ensure your device is in working condition (powers-on) with any firmware...

5. Since you have already used SP Flash Tool, so I presume your ADB drivers are set-up ... Open the folder you downloaded and extracted in step 2 (named A2107A-easy_CWM), move the 3 "recovery.img" files already in there some place else and copy one of the two "recovery.img" files you downloaded in step 3...

6. Run the SP Flash Tool provided within the folder you opened in step 5, choose the scatter file, ensure the new "recovery.img" is selected in the tool and press "Download", a warning would pop-up saying "Not all images have been selected", just press "Yes" ... Now connect device to PC and press reset button on the back of the device, recovery will flash, upon completion a big green circle with "Download OK" would appear ...Press device reset button again...

7. Now power on device directly into CWM recovery (pressing power button for 3 secs and immediately pressing both vol (+ & -) buttons till you get into CWM)...Do all three wipes (wipe Data/ Factory reset, wipe Cache, Advanced ---> wipe Dalvik cache)...Choose the option "Install zip from sdcard" and choose the Stock ROM "A2107A-F_S484_121211.zip" you downloaded and saved to your external sdcard root...

8. In case you don't get into CWM Recovery, use the second of the 2 "recovery.img" files and repeat step 5 and 6...

9. When installation is complete, power-on your device...Hopefully, you'll have the stock ROM up and running...If you have the "/data/nvram" folder backed-up from original device, replace it :)
[Android General] manwithmanypiercings:
Worked like a charm. Thank you!
[Android General] Camborg80-Trey:
Well, everything went well. Except...

Basically, I can boot into the tablet fully (I did not flash the F firmware, I was trying to install cwm). But, after using SP FLASH and trying each of the two recovery.img's, I can't boot into recovery mode.

If I try, the screen freezes at the first Lenovo screen, and does not advance past. If I reset the tablet (you know, disconnect the battery) and turn it back on it will boot all the way through.

It just now has this awkward problem of freezing if I try to get into recovery mode. Since I can't get into recovery mode (I don't even know if cwm is on it at this point), I can't flash the F-firmware :(

I even rooted the tablet and put mobileuncle on it to try both .img's through that, and I got the SAME result for both.

What the heck is going on . I'm so close :(
[Android General] makbro:
Hmm...As you can see in the above post by manwithmanypiercings, who also has a -F model, the "recovery.img" I have posted works...

So the only thing left now is to see if you have a file named "reboot-from-recovery.p" in the folder "/system"...If it's there, just delete it and flash "recovery.img" again !!!

And I hope you don't physically disconnect the battery everytime you have to reset the device cause there is a reset button at the back for that ;)

Here is the reset button (I am posting just in case ;) )
[Android General] brickedstone:
I just tried CWM Foxtrot ROM and that too gets stuck on select country screen. I select a region which it fails to set and thereafter takes me to reboot ad infintum. The only way out again is to restore the original backup in recovery menu. If I am not hallucinating, then someone in this thread had a similar problem with Foxtrot. Can anyone point out to the thread where it was fixed, if at all?

Thanks
[Android General] makbro:
It's fixed if you use the SP Flash Tool version of Foxtrot ROM or the Chinese ROM, not thru CWM versions :)
[Android General] brickedstone:

Thanks a lot makbro, will try it out shortly. But any idea why CWM would not work? I have tested each of your ROMs except stock and all of them run into a problem of similar nature at boot.
[Android General] makbro:
SP Flash Tool overwrites the whole NAND Flash while the CWM Restore ROMs only replace "system, data, cache, boot.img and recovery.img" while in case of the update.zip type, you have to wipe data, cache, dalvik cache and the installation replaces just "system and boot.img" !!!

You would just need to use SP Flash tool once, and then flash CWM Recovery again...After that you would be able to restore/ instal any custom/ stock ROM thru CWM :)

Stock ROM part 2 won't unzip

Hi makbro,

thanks a lot.

I can't unzip part 2 of the stock rom. part one unzipped just fine, USB drivers & flash tool also and flash tool can be started and is working.

Since I can't unzip part 2, I left it in the global folder and tried the procedure without an unzipped part 2. When I reset the device nothing happens and the flash tool seems to got stuck... no big green circle showing up...

Can you advice?

Thanks again.
[Android General] makbro:
:) It's a split .zip, you don't have to unzip the second part, when you unzip the first one, the second is automatically unzipped so you have the complete ROM...

About the Flash tool, it's usage method is different to the older version...The usage instructions I posted include that first you select the scatter file with device unplugged...then select Format or Download (whatever you are doing)...After that, you have to keep the reset button pressed while plugging in the USB cable and release the reset button once the cable is in, not before that !!!

Hope this helps ;)

Any feedback on whether 3G is working for you guys with this ROM ???[/QUOTE]

I also tried ROMs Lewa and Foxtrot but continues on the frequencies indicated by berriosb. How to activate those bands? :confused: Thank you in advance makbro
[Android General] makbro:
Well, sorry guys, this was the last "modem.img" file I had (that was claimed to be working in European Region)...If it doesn't work, we continue search for the correct modem !!!

See it's not only the modem itself, it has to be compatible with the ROM to work...The modem of European Stock ROM is incompatible with all the custom ROMs, so it doesn't enable 3G for the rest !!!

Regarding activation, it can be done thru Engineering Mode (MTK) under item "BandMode", if it is supported by the "modem.img", otherwise, the selection is Frozen only to the default supported Bands !!!
[Android General] Camborg80-Trey:
I tried looking far and wide for that file using Root Explorer app within the tablet and could not find it.

The interesting this is I cannot get to cwm, OR the stock recovery. Screen always freezes at first Lenovo screen. Is it because of my h firmware? I really don't know for sure. The thing boots all the way to the tablet desktop if I leave it alone :(

I'd imagine I"d be able to get to at least the stock recovery if that rebootfromrecovery.p file was there, but like I said I couldn't see it. Do you have any other ideas?

Also, (and you've been VERY kind and I can't thank you enough), if I do go to my local best buy after work tonight and buy another F model to get its firmware, could you give me step-by-step instructions when you get the chance on how to extract everything I need from that tablet and put it on my current, messed up one using SP FLASH tools?

If there is a method to do that I am more than willing to try it at this point. I'll also upload everything to this site for any other hapless soul like myself that runs into this mind-numbing problem.

Again, thank you for everything :)

3G

Well as i mentioned before, 3G is working for me. all the ROM's you suggested are working perfectly for me at least. but now i am using chines one. its base on original OS of Lenovo with value added features. just one thing, its poping that you have a firm update. should i apply and download it ?

I am not comfortable with both LeWa and Foxtrot ROMs since the tablet doesn't have hardware button. pages like about in LaWa when you enter, you can not find back ! so u stick in the page ! i used volume button to make tablet to show the screen back button.

it is for sure that mentioned ROMs are faster. but i prefer the originality of OS.

one more thing, do u have any experience with Ubunto phone. well the demo made me crazy !

it was fantastic !
[Android General] makbro:
Sure, I can post a step by step method to create a Back-up from a new device and then flash it to this one if you want...I wish I was able to help you recover this one without that though but it seems that is impossible except if I have a look at the device and try to remove the SP Flash Tool errors that you have while flashing garringm's back-up !!!

---------- Post added at 09:59 PM ---------- Previous post was at 09:57 PM ----------

That's not much of an up-grade, just a few apps have been added with a few customizations that you can already do with playstore...Moreover, if you update, you'll loose all the customizations and performance boosting tweaks that I have incorporated since the whole "/system" will be replaced !!!
[Android General] Camborg80-Trey:
Yeah, I wish I was more versed in this kind of stuff, unfortunately I'm still a bit of a noob and dont think I could toubleshoot those errors well enough.

Ill go buy that tablet after work tonight and give it a whirl. I will be patiently waiting for instructions from you on everything I have to do.

By the way, you are my hero. Thank you for everything :)
[Android General] makbro:
There's some good news...I have found out what was wrong with the garringm images and have corrected the files, now that back-up can be flashed thru SP Flash Tool !!! So you can try this if you want, only if you have already flashed the -H firmware thru flash tool...If you don't want to experiment any further than just ignore this post ;)

I am uploading the SP Flash Tool ROM, will post the link as soon as done !!!

EDIT : Here is the link to the ROM : http://d-h.st/zYb

And here's what you need to do :-

1. Make sure device is not powered-on and is not connected to PC...

2. Download and extract the ROM...

3. Download SP Flash Tool from here : http://xdaforums.com/attachment.php?attachmentid=1708563&d=1360162416

4. Run SP Flash Tool, click on "Scatter-Loading" and select the "MT6575_Android_scatter_emmc.txt" file inside the ROM folder you extracted above...

5. Scroll down in the lower white window of the Flash Tool, you'll see that "FAC" will not be checked...Click on it (FAC), an explorer pop-up window will open, select the file "fac.img" from the extracted ROM folder (All the rest of the images/ files will be automatically checked and selected)...

6. Click on the "Download" button...Now keep the reset button of device pressed while plugging-in USB cable to PC and release the button when cable is plugged-in, flashing would start...It may take up-to 10 mins...

7. Wait for the big green circle with "Download OK" message to appear, when it does, unplug the device from PC and power-on...

Hopefully, you will have the stock ROM with CWM Recovery (I have included the CWM Recovery in it)
[Android General] Camborg80-Trey:
A million thank yous makbro! I will try this out tonight and report back the results. CROSSING MY FINGERS ON THIS! :)
[Android General] dirtrider146:
I downloaded and followed the instructions, but now when I turn my device on It gets on the first Lenovo screen. Hangs. Doesn't quite make it to the animation. I can get into the Boot manager and tried to do a clear the cache and do factory restart. No luck still for some reason it doesn't seam happy and cant boot.
[Android General] brickedstone:
It indeed works! Now I am on Lewa and don't think I can ever return :) A couple of things though, is v6_supercharge already running in your ROMs? I remember vaguely you were saying something to the effect somewhere. And last, what were those two patches about that you shared along with CWM flashable ROMs? You said that people working with Foxtrot or Lewa might want them.

Please step by step

I'm a noob, so I apologise in advance. I've tried reading through the thread to find the steps needed to root my a2107 -f and I'm having a lot of trouble following... Could someone please list for me the steps and files needed to root my device... (I own a samsung captivate which I've rooted and have flashed multiple custom roms on it but for some reason I'm just lost with the steps for this "new" device)
[Android General] brickedstone:
You seem to have the similar problem that I was asking until yesterday. At the beginning, for whatever reasons, you need to SP Flash a new ROM into your tab. Once it is in place you can install and use CWM to flash as many as you wish. But the first one has to be SP Flash. You can find the procedure in many posts in this thread. Here is one of them:

http://xdaforums.com/showthread.php?p=37294595&highlight=scatter+4gb#post37294595

Also, CWM ROMs won't help your cause and you will have to download an SP Flashable ROM just for this first honors. Here you can find the Foxtrot and Chinese ones:

http://xdaforums.com/showpost.php?p=37419556&postcount=814

As you see, this is all thanks to the awesome makbro :)
[Android General] Camborg80-Trey:
Welp, made one step forward, I guess.

I followed all the instructions to the T. When I ran the SP FLASH tool, the process didn't actually take 10 minutes. It finished (Green circle etc.) after only two minutes. This kind of raised a red flag to me so I pressed ahead anyway.

On the flip side, I was able to boot into CWM without issue. On the negative side...if I didn't boot into CWM, the screen would not advance past the first Lenovo screen.

Kind of angry, I decided to try installing the F-firmware ZIP you made (I had it stored on my sd card still), and like before, it said it installed successfully (I wiped data, cache, and dalvik before running it.

Yet again, I still can not boot past the first Lenovo screen. I can, however, boot into CWM still. I even re-put the H firmware back on, used sp flash with the files you provided, and tried to run the firmware for F.zip from CWM WITHOUT flashing data, cache, or dalvik, and still go the exact same result.

So close. I thought this was it. You had everything down perfect. I just must have the worst luck ever :(

I wonder what the flying hell else I can do at this point. This is going to sound beyond nerdy but my spirit is broken a bit. So much time invested in trying to fix this stupid tablet and it's still winning the battle at every step :(

[Android General] makbro:
Can you get into CWM Recovery ??? If yes then just take out your external sd and use PC to put any ROM in it that I have posted...

If not, then you need to Flash a ROM from SP Flash Tool (either Stock, Foxtrot or Chinese SP Flash Tool version, not CWM)...Then flash CWM Recovery again using Flash Tool !!!

---------- Post added at 12:56 PM ---------- Previous post was at 12:54 PM ----------

Yes, I have included most of the v6 Super Charger performance boosting tweaks to all my modded ROMs including some others...I just left out the Launcher tweaks that v6 did...

About the patches, they are the memory pathces to set either internal or external memory as the main system memory for apps installation, useful for 4GB device holders !!! Ther are posted in the EXTRAS section of my ROMs post here : http://xdaforums.com/showpost.php?p=37409096&postcount=800

---------- Post added at 01:01 PM ---------- Previous post was at 12:56 PM ----------

Now the very last thing to do is before you flash the SP Flash Tool Stock ROM I posted last night thru "Download", first do a "Format" ----> "Auto Format whole NAND Flash" (After selecting the scatter file)...After format is complete, "Download" the firmware files (Again check "FAC" should be selected and this time you won't need to select the scatter file again since it is already selected while doing Format)
