So, in Flash Tool, after format the whole flash, I click on Scatter-loading. Browse the file "MT6575_Android_scatter_emmc" after I modify it for 4GB device.

Now, I have only two boxes checked:

1. Preloader with the path to the "preloader_lenovo75_a2_ics"

2. Recovery with the path to the "recovery_CWMR_5504"

3. Check the DA DL All with Check Sum

I don't know where should I put the path to the chinese ROM? And then click on Download.

Maybe I should put the ROM in the SP_Flash_Tool_v3.1206.01 folder

Ignore the above

I managed to flash the Chinese version but now, it's stuck on Lenovo logo

Thanks

Random Reboot

Hey Macbro,

Just a few issues here. I'm running v3.

1. I am experiencing random reboots just out of the blue (i think its after I updated the go launcher - don't update the launchers !!!!)

2. The radio keeps going off (again while go launcher is active)

3. Phone feature is buggy. I can call but if someone calls me i can't answer. (it displays: "Unfortunately the process com.android.phone has stopped")

Thanks

Alex

Makbro_V3

Don't try this rom, use the others, i experienced the same bugs! Read backward other posts from Makbro and my experience!! ciao!
[Android General] makbro:
Alex is right, the v3 had bugs in it which have been fixed in the final versions of the ROMs that I have updated today...Use any one of the versions I have uploaded now...Personally I have found the modded Chinese and LeWa to be working bug-free, modded LeWa is the best in my opinion :)

---------- Post added at 09:51 PM ---------- Previous post was at 09:49 PM ----------

I think you realized that in your previous post, you were trying to flash just the CWM Recovery...For any ROM you want to flash thru SP Flash Tool, you have to open it's own scatter file (Provided within the folder of that ROM) and make sure that all the images being flashed are also from the same directory...

And you can place the ROM folder any where, just browse to that folder in SP Flash tool by clicking on "Scatter- Loading" and open/ load the scatter file of the ROM you want to flash :)

No 3G connection

Hi makbro. Congratulations and thank you for the tremendous support you give us :good: . I have a little problem, in any of the ROMs that you have given us, can we unlock the frequency band to 850 MHz and 1900 MHz? :confused: With MobileUncle I saw that these ROMs only use UMTS Mode: WCDMA-IMT-2000 and WCDMA-GSM-900 as base band. But 3G doesn't work on those frequencies in Peru. Thank you very much for your support. :D
[Android General] makbro:
I would need a "modem.img" file that supports this band for the MTK65xx chipset...If you can send me that, I can cook a ROM for you with that support, all the modems I have now use the same bands as you posted :)
[Android General] BBLoo:
Yes I just realize how dumb I was.

Thank you Makbro.
[Android General] lenizzita:
Thanks makbro. I'll try to get that file.:D
[Android General] makbro:
One more thing...have you flashed the European Stock ROM ??? That includes a different modem that I am not sure supports extra bands or not...If it has the support for bands you are looking for, then we don't have to look for this file :)

Don't worry, you are definitely not...we have all made these kind of mistakes...that's how we learn right ;)

Hi Makbro

The european rom have the band of 1900 and 850 for the 3g in peru if you could make a custom rom with the base band was wonderfull.

i think you just have to replace the file modem.img on this \system\etc\firmware folder ,i'm from peru i didn't do that, but i think you can do it, if you want it i have that modem.img file
[Android General] xkikinx:
Thanks 4 everything Makbro, just to comment, I am from Peru and I have flashed the european stock (clearsky) and the 3G works just fine; however, the chinese rom from chinapad doesnt allow me 3G.

BTW, I have a back up that I made with MTK tools. Where can I find the modem.img you were asking for?
[Android General] thunder141:
If to use stock rom, is it possible by changing some files in the stock zip by your mod zip to get the full tts support like in the mod rom?
[Android General] makbro:
If the European Stock ROM is working for you guys, I'll cook the modded Foxtrot and LeWa with that "modem.img" so that your 3G could work...

So don't need to send me anything, just wait...I'll do it as soon as I find time ;)

---------- Post added at 01:18 PM ---------- Previous post was at 01:11 PM ----------

I think the "tts engine" is initialized in the "boot.img"...If it is so, you'll need to extract "boot.img-ramdisk" and "zImage" using Android Kitchen and then unpack "zIamge" using "initramfs utilities"...Then you can see where it is initialized and make the change accordingly...After that, do the reverse process to build new "boot.img" :)

If it's somewhere other than "boot.img", it would be easier...I can't say for sure as yet ;)
[Android General] lenizzita:
Thanx johnmilthon, :good: but I think it isn't so easy. I already tried to do it but that didn't work. Just change that file and boom!! removed completely internet connection :S But I read that makbro will prepare a special ROM for us. :D

---------- Post added at 11:21 AM ---------- Previous post was at 11:13 AM ----------
[Android General] makbro:
:) It doesn't work this way with .img and most of the system/ firmware files...The .img files are extracted and installed during the first boot so just replacing them won't do the trick since the older file is already installed and in use, may even cause a conflict and the baseband may stop working ;)
[Android General] lenizzita:
OMG! You're so fast makbro! I'm going to try it now. Thanx :D :good:
[Android General] xkikinx:
Thanks Makbro, you are great. I'll definitely give it a shot! ... Thanks

I tried Chinese Rom and 3G didnt work :(
[Android General] lenizzita:
Hi makbro. I don't know what I did wrong. I had installed the latest version: A2107A-H Foxtrot modded ROM (Jan. 22th.) All that remained was to have the 850 Mhz band. Today I installed: Modded Foxtrot A2107A-H_S222_121121_MAK_EU , but it doesn't update the band mode, in addition, this version doesn't bring all the previous apps, for example, radio, mobileuncle, etc.

I don't know what else to do. I already flash the tablet with SPFlashtool, wipe cache, data and Dalvik cache, but nothing happens.

Sorry to be annoying but please I need your help. :crying:

HELP! Bricked tablet

hey guys I really need help I bricked the hell out of my tablet. I have the a2107a-f model. Iiterally BRICKED it trying to flash roms for the h model on it. Luckily i was able to use the european stock rom for the h model on my f model via the flash tool and get it to fully boot up again, except it glitches really bad since the firmware I have for it is for a different model.

I know a user posted their f model image earlier in the thread, but when I try to use it via the flash tool, I get scatter loading errors.

PLEASE, ANYONE, where can I get or find a full flashable (not rom) stock American F model firmware I can successfully use with Flash Tool? Once I get this my device will be saved and I can go back to being a happy owner of a non-bricked device. If ANYONE could help me I'd be in your debt!

thankes to all

Hey guys

thanks very much to this fourm

and thanks too much for

pemergency

i tried to do it and every thing working very well

many thanks to all

​
[Android General] makbro:
You didn't need to use SP Flash Tool, I mentioned in my first post with ROMs that these are installed thru CWM Recovery...Moreover, when a new ROM is flashed, you are required to wipe data, cache and dalvik cache since the app settings from previous ROM may create conflict with the new ROM, which you did correctly...

To restore all your apps, you need to use app "Titanium Back-up" to create a back-up of apps + data which you can restore by installing the app again and using the back-up folder to restore all your apps...I presume you haven't done that so there is no chance of getting old apps + data back...

If you created a CWM / Onandroid back-up, you can restore previous ROM fully with apps + data...

Try using the LeWa modded ROM with EU modem and see if the band becomes operational, as I said, I cannot verify it since bands are different here !!!

---------- Post added at 12:57 PM ---------- Previous post was at 12:54 PM ----------

I have posted the European Stock ROM for the -F model in this post (First ROM) : http://xdaforums.com/showpost.php?p=37409096&postcount=800

[Android General] BBLoo:
Hello,

Makbro, this patches work on the european stock rom?

I have the 4GB version and I want my games and apps to be installed on my 32GB external microsd.

I think there are many of us who own the 4GB model...

Thanks
[Android General] makbro:
Yes they would, they need to be installed thru CWM Recovery as "Install zip from sdcard"...You should use the "patch_main_to_sd2" one to make external sdcard as main memory :)
[Android General] xkikinx:
Hi Makbro, I just flashed Lewa EU and I couldn't get 3G connection.
[Android General] Camborg80-Trey:
Would you happen to have the scatter file and all other associated files with it for the F model that work in the Flash Tool?

Reason I ask is because I had a very serious problem trying to get Clockwork Recovery installed before brick the tablet. I'm scared I won't be able to get it on and the Flash Tool works for me if I have the appropriate files.

[Android General] Camborg80-Trey:
So I have a question...

After extracting all the files, I had to rename the scatter.txt to something else because Flash Tool said the filename was "illegal." (I renamed it to MT6575_Android_scatter_emmc and it loaded it fine).

However, the only box that is checked is the BOOTIMG box. As a result, Firmware - Upgrade option cannot be used. Am I supposed to just click "Download"?

Also, do I have to flash the tablet first? Or make any adjustments to the scatter file (I have the 8 gb model).

Thanks again for the help. :laugh:
[Android General] D1358531:
I'm not really sure :laugh: Maybe makbro will know more about this?
[Android General] makbro:
1. Since your device is 8GB, edit the scatter file and change "FAT 0x924e4000" to "__NODL_FAT 0x924e4000" BEFORE flashing...

2. If your device is bootable and with a working ROM, you have to use the "Firmware-Upgrade" option...About only bootimg being checked, just click on the rest of the fields (one by one) and select the files manually (from the ROM you want to flash) and check the boxes yourself :)

3. If your device is not bootable OR the ROM has glitches, you must first load scatter file, select "Format"--->"Auto format whole NAND flash" and then use "Download" option in step 2 above with "DA/DL all with checksum" selected...

Hope I am clear enough ;)

---------- Post added at 01:30 PM ---------- Previous post was at 01:25 PM ----------

You can do that thru "BandMode" option in Engineering Mode...You can enter Engineering Mode either by entering * # * # 3646633 # * # from dialer OR using Mobile Uncle Tools----> Engineering Mode MTK----> BandMode

@makbro..

sir makbro is there any other way that i can enabled the calling features for this model "ideatab a2107a-h" i bought this table recently but i discovered that i cannot placed anycall. I put already my sim card on it but still the same.. Upon reading this thread i noticed that i need to root first.. is there any other way that no need to root my tablet just to enable my calling features....
[Android General] makbro:
I am afraid without changing the Stock ROM, it's not possible...For that, you would need a device rooted and with CWM Recovery installed !!!

thank you sir for the fast reply.. I have another question i received also n update to my tablet but when i update this nothing happen same version 4.03 strange thins also is that i dont receive any error message..

About the update, your "Build Number" under "Settings" would have changed, Lenovo OR OTA has not released the full Android update for this device yet (4.0.4 OR Jelly Bean) :)

I installed the 3 modified roms eu (lewa, foxtrot and chinese) but nothing have 3g function, i upload the modem img of the stock european rom version s309 that have 3g working in my country (peru) please cuold you make a new rom with this modem

[Android General] makbro:
For those interested in restoring stock ROM (completely out of the box one), there's good news...I have successfully collected all the required images, flashed and tested the stock ROM version A2107A-H_S309 (without S341 or S345 update)...You'll even loose the Rooting and CWM Recovery after flashing (without trace), in case of a warranty claim requirement ;)

The only catch is it is the SP Flash Tool version (haven't been able to cook a fully working CWM version of it yet)...

Will post the stock ROM and the modded ROMs with the new "modem.img" provided by berriosb tomorrow morning (EEST) :)

[Android General] Yann68:
Makbro, do you know why the Lewa lockscreen look like that?..it's not centered.
[Android General] makbro:
All the files being shown in the lower box of the Flash Tool after you load the scatter file...As per the scatter file that was posted by D1358531, these would be :-

PRELOADER

DSP_BL

MBR

EBR1

UBOOT

BOOTIMG

RECOVERY

SEC_RO

LOGO

EBR2

ANDROID

CACHE

USRDATA

FAT

If your model is not 16GB, then you would have changed "FAT 0x924e4000" to "__NODL_FAT 0x924e4000" and would not choose "fat.img"...

Stock & EU ROMs

The SP Flash Tool version of Stock ROM A2107A-H_S309 :-

Part - 1 : http://d-h.st/IU5

Part - 2 : http://d-h.st/0wB

4/ 8GB device users should not flash "fat.img", change the "FAT 0x924e4000" to "__NODL_FAT 0x924e4000" in the scatter file...

EDIT : Have taken-off the EU versions again since 3G still not working (as per feedback) !!!
[Android General] makbro:
The attached image showing the files to be flashed are not the ones to be used with SP Flash Tool...The files used for flashing thru SP Flash Tool are either ".img" files or ".ext4.tar" files...I think it was garringm who posted these images for the -F Stock ROM somewhere in this thread...

EDIT : I have attached two snapshots as examples in my next post--->
[Android General] makbro:
I have attached two snapshots of example SP Flash Tool flashable ROMs with this message :)
[Android General] makbro:
Moreoever, these files that you get after extraction belong to the same CWM Flashable ROM that I cooked for D' and have uploaded with the other ROMs as well...They are not to be extracted since they are "ext4.tar" files and are automatically extracted and installed by CWM Recovery...This is not SP Flash Tool flashable ROM :)

A bit of a miscommuncation here...

What I need is an SP Flash Tool FLASHABLE ROM, and I need this for my a2107a-f model because I am having immense difficulty getting CWM on the tablet at all.

I already used garringm's image for the SP Flash Tool, but the firmware is for the H model, not my F model. If I use his, the device boots up completely but glitches really bad because, again, the firmware is for the H model, not the F model.

Is there a brave soul out there who happens to have the A2107a=f model rom that is an SP Flash Tool flashable ROM? All I need is this and I'm up and running, good to go!

Thank you.
[Android General] makbro:
Sorry about that, garringm clearly stated in his post that the images are for the -F model...I didn't check either, since I have -H !!!

I guess now the only option is someone backs-up his -F device using Gscript Lite OR MTK Droid Tools and offers you the image files :)

Hi Folks,

I have a A2107A-H which I messed up. I managed to delete pretty much everything I shouldn't have.... SuperSU and Browser are left. Settings are gone too, so I can't even connect to wifi... and it seems I can not install anything. Factory reset brings nothing else back either. Yes... my name is sad reality. :crying:

I checked the thread in detail, but I'am slightly confused.... too many models, downloads, links, languages etc. and I don't want to make it worse... if this is even possible.

Any chance that somebody has or writes a summary for a A2107A-H (english) on how to bring it back to original state by connecting it to a computer, incl. links to required software and other stuff?

I know it's a lot to ask.... eternal thanks will be yours... :angel:

Hello makbro... does any of these roms support arabic language? And where to find the nvram file? I canot find it thanks
[Android General] makbro:
No, I am afraid none of these supports Arabic Language...Only my stock ROM has that option and it's in SP Flash Tool version...I cannot separate my personal data from it and if you flash it without the data.img, it will give you problems !!!

About the nvram, it's not a file, it's a folder and can be found as I posted at "/data/nvram" (root of device once you open the Root Explorer) :)
[Android General] makbro:
Use the ones I have attached :)
[Android General] makbro:
I have researched in detail and the solution is the same as before, we have to find the correct "modem.img" that is compatible with the specific custom ROM to be able to change the bands...We should just keep looking till the time someone finds that !!!
