USB OTG doesn't work with the A2107A-H...That's the official verdict on 4pda forum :)

---------- Post added at 12:41 AM ---------- Previous post was at 12:38 AM ----------

In contrast to voltage, amperage is drawn by a device according to requirement so a higher amperage charger will work fine, as long as the voltage is same :)

Which ROM are you flashing ???

There are a couple of things you could do...

1. If your device is booting-up normally with any ROM, you need to open the "MT6575_Android_scatter_emmc" file in Notepad ++ and add "__NODL_" before "FAT 00xxxxxxx", save file and then flash ROM...

2. You may use a ROM that has "fat.img" file in it and select in manually by clicking on "FAT" field in the flash tool and browsing to it if it's not automatically selected...Remember not to use "fat.img" from another ROM though !!!

Hi. The link to your rom can than I will help. You do it on a basis MIUI? When I was making my MIUI_v4 then probyval different plotnosti.Samye multiple possible settings were optimal at 190 - 220. Future versions I settled on 230.Esli to sink to change to a value more than 160 is in my experience the bottom panel and not working at all glyuchit.Kak something like this.Sorry my bad english.

Hmmm...At this stage, you may follow the steps in this post and flash the Chinese ROM in step 2 (a) :- http://xdaforums.com/showpost.php?p=39219999&postcount=1280

After successful boot-up into Chinese ROM, you may flash CWM Recovery again and then flash any CWM based ROM !!!

3) After the installation will be prompted to reboot in recovery mode.

4) Use the volume, select "Backup and Restore", press the power button to confirm.

5) Select "Restore" or "Restore from internal sdcard" depending on what memory was to chip firmware.

6) confirm, wait until recovery "restore" the system.

LCD 180 Diff. You deodex firmware ? Initially no calls, if you add tissue problem . Calls only to port it to the firmware A750 or similar smartfonе.

And the original firmware , without your patch where you can watch or download ? For comparison .Button to add a problem after increasing LСD.
[Android General] crashpsycho:


I have a 16gb device yes I've always de odex plus I plan putting a few themes together. And to make sure if I do port the phone option over to this device it would be from a similar devic like the a750. Would you screen shotting what changes you make to ut the navbar
[Android General] Velial39:
You mean what changes ?About the button or what?
[Android General] crashpsycho:
Well I went in and vhnaged the density to 200 and still no Navbar unless I didn't understand your instructions
[Android General] Velial39:
In the build-prop knock you must manually register

qemu.hw.mainkeys = 0

It is only by increasing LCD.Esli leave this change in LCD160 then all the buttons will not.With increasing LCD will not interface tablets.

I'll try to add the missing files in the firmware

Hey all...I threw this on the ROM thread too, but hoping I can get some help. Thanks!

I was wondering if you could help me add CWM to my Lenovo 2107A-F?

Ive gotten as far as rooting it. I was able to talk to it via the ADB shell too, and was able to access SU. my issue is I cannot, for the life of me get CWM on. I Copy/Paste a few different Images & Zips (trying both) to my USB & SDCard. Ive tried using MobileUncle (I downloaded the APK file, and installed it.) I use the option 'Flash Recovery from SdCard and it then asks me several times to grant SU powers. So I do..then i goes into a recovery that states the following:

Title up top says: Android system Recovery <3e>

Android System Recovery utility

(options menu)

Then below it has a dead android with a Red "!" symbol and the following:

--Install /sdcard ...

E:signature verfication failed

signature verifcated failed

Installation Aborted

I can wipe the cache to 'fix' the android, but when I try installing the zips using 'apply update from sd card' I have the same end result.

Im trying to throw the barebones rom on their ultimately, and would love some help. Maybe a small step by step? Thanks.
[Android General] bakuLaw:
success install

hi sir makbro,

after editing the scatter files as you told to edit the FAT files,

everything goes well,

i installed Foxtrot ROM with call function.

thanks and more power :good:
[Android General] makbro:
Hi there,

First of all, you have A2107A-Fas you mentioned...All the custom ROMs posted on this thread are for the A2107A-H...

Secondly, these custom ROMs can be flashed using the "Install zip from sdcard option" under CWM, not "apply update from sdcard"...I presume you are using the Stock recovery of ICS...You have to use CWM 5.0.x.x or later for these custom ROMs...However, you should only try to install a ROM for the -F not -H :)
[Android General] Tuffshift:
Oh. Im sorry thank you for the clarification. Im just stuck trying to get cwm even installed on my tablet
[Android General] crashpsycho:
At 200 density not 240. 200 will work jut fine
[Android General] makbro:
Use "csns" UPDATE 3 method (SP Flash Tool one) from the following post and flash the attached "recovery.img"...It's for the A2107A-F :)

NFSHP

the sound of Need For Speed Hot Pursuit while playing is somewhat robotic/delay,

any tweaks to improve the sound or this device is not for gaming,

cuz Temple Run 2 and Angry Birds is working well,

only NFSHP sound is not good
[Android General] makbro:
I know it may not seem to have a direct impact on game sounds but try to install "IVONA" TTS engine and select it as default instead of "pico" or "google" ... I have that and it does have the desired effect on games :)
[Android General] Tuffshift:
Thanks. Sadly I tried pushing a similar recovery manually using ADB Shell, and I while it was able to load on the PC (File transfer over,) it didnt take..and I bricked it. Now It just loads and sticks at the 'lenovo' screen. I also cant talk to it anymore via adb, and my pc wont recognize it.

Anyone ever have success with unbricking/getting around this on any 2107a? It was my fault, but just sad to have a brand new paper weight.
[Android General] makbro:
The good news is that "MTK 65xx" chipset based devices CANNOT BE BRICKED :)

If you have a Lenovo logo after power-on, SP Flash Tool will connect to the device provided drivers were installed on PC...Try flashing the attached UNBRICK ROM (Courtesy FoxtrotKZ and manwithmanypiercings) using SP Flash Tool...This is not a complete ROM (No /system) but after flashing, you would have CWM Recovery which you can use to flash either your CWM back-up or one of the two A2107A-F ROMs I've posted !!!
[Android General] Tuffshift:
Well thank you very much for your swift response. You have no idea how I felt this morning getting e-mails that my screen/protectors & case shipped for a non-op item.

I will have several questions if your okay with that. I know as for the drivers I could NOT get windows 7 to manually install a google usb driver (one recommended I saw, around) so I had to download some program that had the word "PDA" in it to get it to work..after that it recognized my tablet (2107A-F) and I was able to ruin it from there..lol.

Post Intentional Accident - When I plug my Tablet it (once it charges,) my computer does make the normal 'tones' as if It has recognized a new device. That PDA program also takes not that a tablet has been hooked up. Although if I search under Decvices in the control panel, im pretty sure it is listed as an unrecognized device.

Thanks again for your swift and informative response. I will need future help, but Ill make sure my next reply is detailed with whats going on once I get home.
[Android General] jonessl:
Hi, Makbro, that's really good. Will the same utility work with a A2107A-H as well, please?
[Android General] makbro:
Sure, it's the original solution posted by FoxtrotKZ for seemingly bricked A2107A-H...I just modified it using manwithmanypiercing's stock back-up for A2107A-F :)

I have attached the A2107A-H unbrick ROM with this post !!!
[Android General] jonessl:
Thanks, Makbro, that's really good of you!
[Android General] Tuffshift:
So success...sorta. I was able to use the unbrick via Phone Flash Tool...and im while the format/download is a success after I hit the reset on the back the tablet will only turn on when plugged into a PC (It will boot to 'lenovo' logo where it just stalls.) It will not turn on at all if unplugged. Also, I for the LIFE of me have tried to get this into the recovery screen but cannot. I hit the power button for 3 seconds, quickly let go and hit the +/- symbols and nothing.

Also as mentioned it will not turn on/stall at the lenovo screen if not plugged into pc. Once I plug it is I get this blue bubble screen and a battery with 1/3 have an orange frame on it, charging. If I hit the power button again, it will load the the lenovo screen and do nothing.

Again I have had several different attempts at loading the preloader/recovery but cannot get into it!

EDIT - When I follow these instructions:

It does not take 13 minutes..it does go through several colored bars..and says Ok (Green Circle) but this is all done within a minute.

******While I would love to do the Update 3 by csns, I cannot. Remember once I use the unbrick method, etc..I cannot get into CWM, not past the lenovo screen.

**************Note - Under "SP_Flash_Tool_FULL_A2107" There is a folder "A2107_ClearSky" with is a full SP rom. If I upload this one, (This one takes roughly six minutes to install, instead of the 1 minute like the others,) I get past the lenovo screen..to the lenovo 'chime' sound and a choppy lenovo logo going across the screen. It then hangs THERE. If I do a hard reset I can get into the bootloader/recovery screen labeled "Android system recover <3e>" by pressing and holding + & - right after a reset (tablet totally off). In the center of the screen it reads "E:failed to open /sdcard/update.zip (No such file or directory)

E:sinature verification failed"

Again this is only under clearsky atm. Sad...but its something..
[Android General] Tuffshift:
Slight Update. Given I could get into what I think is the stock boot/recovery area using Clearsky...I tried it (Holding the + & -, then the long pressing the power) under A2107_F_UNBRICK, it didnt work. I next uploaded A2107_ANTIKIRPICH and it did work! Finally for the first time..I have progress! Im downloading the stock & barebones rom to an sd card as I type. Wish me luck!

*Sorry if this seems like spam..im just wanting to leave a trail for others who may have an issue like me on a 2107A-F, and so the guru's know what ive done..lol

---------- Post added at 12:38 AM ---------- Previous post was at 12:30 AM ----------

Okay, now while I do have the roms loaded on an external sd card, im getting "E: Cant mount /sdcard/"

Ok. If I try installing the stock A2107a-f_s483_12115.zip, I get an error (status 0) Installation Aborted.

If I clear everything and install barebones, it installs and i get install from sd card complete, message. When I reboot the system it still hangs on the lenovo screen.
[Android General] Tuffshift:
Looking for a hero - ive managed to try and install both the stock and barebones rom via cwm v5 and v6 (yes im clearing cache and the other two,) and with no luck im still stuck at this pesky "lenovo" screen. No animation just boots to the lenovo screen or i ca. Reset and boot to cwm.

Any ideas?
[Android General] makbro:
As I told you earlier, all the ROMs available out there are for the A2107A-H, including "Clearsky"...By trying to flash that, the hardware configuration of your device has been seriously messed-up :(

If you have followed Step 5 of my procedure referred in your post above (Auto Format whole NAND flash) and still no result, I have no more ideas...May be someone in the -F thread would be able to help you !!!

In case you haven't formatted the NAND flash before installing ROM, try that...But remember, immediately after NAND Flash format, you must flash the UNBRICK ROM, then flash ".zip" ROM using "Install zip from sdcard" option under CWM 5...If you don't get CWM after UNBRICK ROM, follow UPDATE 3 procedure of csns but use the "recovery.img" file that I sent you to flash CWM recovery and then flash the -F ROM (http://d-h.st/Q4t) !!! You can try out the SP Flash Tool version of this ROM also that I uploaded here : https://www.dropbox.com/s/jv0mw4gnrolan7a/A2107A-F_S483_121115_SP.7z

I hope it works out for you !!!

ROMs

sir makbro,whick ROM is better,

Foxtrot,permergency or tasemartmod?

my ROM now is Foxtrot and my dial keypad is somewhat small {attach},

while in tasemartROM,the keypad is almost half the screen as i watch the video.
[Android General] makbro:
As per my opinion, Foxtrot is the best one amongst the ones you mentioned...If I remember correctly, the Tesmart dial pad is the same size but I can't be too sure since I switched to LeWa and Foxtrot long ago...Moreover, the Tesmart dialpad has only one SIM dialing at a time whereas in Foxtrot ROM, you can choose which SIM to make a call from the dial pad itself :)
[Android General] AgustinArwin:
Has anyone successfully installed Hack Google Now on A2107A-H? If yes might giving me instruction.

[Android General] makbro:
Again Foxtrot since it give you full functionality including SIM Management from Settings menu, Dual SIM calling from dial-pad, TTS etc :)

LeWa supports higher resolution and some other enhancements like V6, Turbo Net (3G and WiFi), touch enhancement and LCD density of 200-220...

However, you can add all enhancements to Foxtrot ROM as well by "build.prop" tweaks (except LCD density) !!!
[Android General] makbro:
"build.prop" TWEAKS

Hey there everyone,

So I've been reading a lot about custom tweaks to enhance Android device performance like "V6 super charger"...I also analyzed the custom ROMs like MIUI and LeWa to gather a set of all performance enhancing tweaks...After careful vetting and testing, I've come-up with a mixture of all positive tweaks (from all available scripts) that enhance the performance of our A2107A-H without creating any problems...So here's what is needed to be done :-

1. Device has to be rooted.

2. Run "Root Explorer".

3. Browse to "/system" and select "Mount R/W".

4. Open the file "build.prop" in "text editor".

5. Copy all lines in the attached text file at the end of your "build.prop"... Remember to leave one line blank at the end of "build.prop" file.

6. Save the new "build.prop" and reboot...Your old one will be automatically saved as "build.prop.old" by Root Explorer which can be restored if

something goes wrong...Nothing would go wrong though since I've tested these tweaks for long now without any issues !!!

7. Enjoy the enhancements :)
[Android General] AgustinArwin:
WHAT!!! Foxtrot can do that!

What version of Foxtrot are you using? any bugs you found? How to flash Foxtrot? I can't understand Foxtrot's 4pda thread even when translate (Google Translate) (I have 4GB A2107A-H)

Backups made from MTKdroid can be restored by SP Flash Tool right? what version of SP Flash Tool should I use?

How about the ICS ported google now have you successfully install it?

Thanks,
[Android General] bakuLaw:
thanks for this,

after applying new build.prop i noticed the net speed,

much faster now than b4, :good:
[Android General] makbro:
I am using "Foxtrot v100" and I have added the features of "Foxtrot v110" to it myself along with the "build,prop" tweaks I posted...Absolutely no bugs at all...You can install the modded Foxtrot I have posted using CWM 5.0.x.x and then install the Foxtrot v110 apks manually later (not the complete update cause it will make Russian language default for the new apks)...Link is in my signature...

Theoretically yes, MTK Droid back-ups can be restored using SP Flash Tool...However, I wasn't able to do that myself on this device...I used the "Gscript Lite" back-up, that's a better option in my opinion...Within "Gscript Lite" back-up, the best method is to restore the CWM back-up it creates in the "BDRS----------" subfolder (within the main back-up folder "backup_v2") using CWM 5.0.x.x...As regards to SP Flash Tool, I have used both "V3.1224.01" and "V3.1216.02" without any problems...Both have slightly different method of flashing...

I haven't tried the ICS ported Google Now yet...

Straight answer.. Did I Brick my device ?
[Android General] makbro:
MTK 65xx devices cannot be bricked; so, NO YOU DIDN"T BRICK YOUR DEVICE :)

---------- Post added at 12:52 AM ---------- Previous post was at 12:23 AM ----------

@crashpsycho...Try to follow this procedure :-

1. Download the "A2107A-H Unbrick ROM" by Foxtrot_KZ from here :- http://xdaforums.com/attachment.php?attachmentid=2070714&d=1372247425

2. If your device is 16GB, skip this step...If your device is 4GB or 8GB, browse to Stock ROM folder (downloaded and extracted in step 2)... Open the file "MT6575_Android_scatter_emmc.txt" in Notepad++ and change "FAT 0x924e4000" to "__NODL_FAT 0x924e4000" (There is a double under-score before NODL and a single underscore after NODL)...Save file...

3. Make sure device is not connected to PC and is powered-off...Run SP Flash Tool V3.1224.01 "Flash_Tool.exe"... Click on "Scatter-loading" button, browse to the Unbrick ROM folder (downloaded and extracted in step 1) and select file "MT6575_Android_scatter_emmc.txt"...

4. Select "Format" from Flash Tool menu and then "Auto format whole NAND Flash" and click OK to format device...Now plug-in the device and keep the "Reset" button of the device pressed while plugging in the USB cable to your PC and release the button once cable is plugged-in...A big green circle appears with "Format OK" indication...Disconnect device from PC...

5. After format, check the box "DA/ DL all with checksum" and click "Download" from main menu of Flash Tool and click yes on the dialog box that says "not all images were selected"...Now again keep the "Reset" button of the device pressed while plugging in the USB cable to your PC and release the button once cable is plugged-in...The ROM will start flashing to the device...Don't do anything until the big green circle appears again with "Download OK" indication...

6. Power-On the device once, you should get the first Lenovo logo (not the second splash screen)...Then again use SP Flash Tool to flash the Chinese ROM (available here :- http://dl01.chinapader.com/ROM/A2107A_H_S121_120525.zip) using the Download option (no format this time) using the same method as step 5...This time, it will take approximately 13 minutes with 7-8 different color bars completing 100% progress before "Download OK" appears...

7. The next power on would hopefully boot into Chinese ROM :)
[Android General] crashpsycho:
OKAY i got the splash screen but for some reason its still not working in SP flash tool the end time is always around 6-9 minutes and i only get 3 colors red yellow grey and grey loading up around 4-5 time i think but since doing the second part i no screen for splash nothing now... UGH! very frustrating lol any other input you can add to these details
