[Android General] makbro:
Need help

Hi everyone,

Need help, whenever I try to restore any ROM from "CWM recovery" option "Restore" or "Advance Restore", I get error message "error while restoring /system"...This includes pemergency ROMs as well !!!

Thanx in advance !!!

Hi csns,

Which procedure did you use to install Chinese Stock ROM of ichigo...the one in "flash how to.doc" ???

Thanx in advance
[Android General] makbro:
Got Chinese stock ROM working !!!

Never mind, I got the Chinese Stock ROM up and running without any problems :) The language changed without any problem, phone calls working and also the radio...Now going to add Google services :)

Best ROM

Hi guys,

After trying all the available ROMs for our device, the following works best without any problems at all :-

http://4pda.ru/forum/index.php?showtopic=286687&st=920 (go down to the post labelled "A2107_Foxtrot_v100")

The forum is in Russian but you can open the link in google translate with a decent enough translation into English...The ROM can be installed via "Restore" Option of CWM recovery...Do remember to do the wipes before installing this ROM...Language can then be changed from System Settings after reboot !!!

Thanx for all the help and support to all you guys, specially pemergency, couldn't have done it without your help !!!
[Android General] Cristian.Ene:
Is the call function available?

Is the data over sim available?

Thank you for your answer
[Android General] csns:
All works.

Just the letters on the dial pad stay Russian even in you change the system language.

Or at least I can't find the way to change it...
[Android General] manwithmanypiercings:
Have you tried installing a different keyboard?
[Android General] csns:
:)

No, I don't care about the dial pad - I'm not going to use it anyway.

Just wanted to test this feature :)

BUT if someone can provide a link for a full STOCK (unchanged) ROM of the European model (A2107A-H 4GB) I would appreciate it a lot.

Thanks.
[Android General] Cristian.Ene:
Ignore this message post
[Android General] makbro:
Yes all features work and checked by myself except data over SIM, will let you know as soon as I do

---------- Post added at 01:12 PM ---------- Previous post was at 01:06 PM ----------

The letters on the dial pad have Russian on top of English alphabets in my case, so I have both !!!

BTW, thanx to you as well csns, I got CWM recovery as per your procedure posted in the other thread :)
[Android General] pemergency:
If you want to change your keyboard to normal english one from foxtrot mod just swap framework-res.apk in system/framework folder with the one provided on a botom of this post.

just remember to copy framework-res.apk to the system folder first, change a permission by a root exploerer and than copy to system/framework folder.

If you will not change permission before replacing framework-res your system will not boot!!!!

Permission for framework-res should looks like this
[Android General] csns:
Didn't make any difference for me...
[Android General] pemergency:
You are right. The file need to be changed is contact.apk in app folder. Dont forget about permission
[Android General] csns:
The original file got overwritten - just compared MD5 of your file and the one in my framework folder.

Permissions are the same.

So I did it right.
[Android General] pemergency:
Yes I edit my last post... with corect solution
[Android General] csns:
That's it.

Swapping Contacts.apk (and Contacts.odex to be on the safe side) with ones from your ROM worked just fine.

Thanks.

Jelly Bean update for a2109

Hi guys,

Lenovo US ported OTA update notification for it's a2109 devices in the US, rest of the users can download updates from Lenovo servers...The update is for Android 4.1.1 Jelly Bean...Trying to port it for our a2107 as well, but I'm really really new, so would take time...

Wanted to inform all of you so that you may start work in parallel, with all the likelihood that one of the experts here can do it much earlier than me :)

After flashing one this roms, has anyone experienced problems when plugging in the headset? In my case, when I plug in the headset the sound will go through both the speaker and the earpiece but the icon doesnt show up in the notification area. Sometimes the headset icon will appear after i unplug the headset. It is weird :S Thanks for your help!

Just open settings of superuser app, press the right top button with an icon shaped as spanner, select "settings", then "Automatic Response" and choose "Allow"...

Did you perform all three wipes before flashing the ROM as described by pemergency tutorial ??? If you did there shouldn't be such a problem !!! Hope this helps :)

Hi guys,

I still happen to have the Original European Stock ROM for this device...Slight catch though, since I got the device from UAE, the default language may be Arabic once you flash it, this can be changed from the settings menu of course :)

If someone is interested, I can send you the ROM, just PM me :)
[Android General] xkikinx:
stock

Did you get my PM... I tried but it doesnt appear on my outbox panel...
[Android General] makbro:
Yeah I did and sent u a reply also, sorry for the delay.

Note for anyone else interested...I created a Nandroid backup of my Stock ROM before flashing modded ROMs, it turns out the stock ROM is not being flashed properly, CWM restores the ROM with no errors but the device doesn't boot...

I'll add links to the stock ROMs as soon as I figure out what's wrong !!!
[Android General] pemergency:
download and install superuser from google play
[Android General] csns:
I have the same problem.

My guess is that the boot.img needs to be flashed for example with SP Flash Tool.

This makes sense especially if you erased the whole memory to install a custom ROM which seems to be using a modified boot.img

And yes, I do have a backup of my original boot.img but for some reason it is the same size as my original recovery.img and... it doesn't work if I flash it :)

The scatter loading file for A2107A is generally an address map of the whole "memory chip" so use it to flash the original boot.img to your tablet and let us know if that helped.

Good luck!
[Android General] makbro:
Thanx

Thanx, I'll try and let you know :)

Stock ROM flashed !!!

So I was able to flash the Stock ROM back with latest update as well, only problem left now is it doesn't show the IMEI info i.e. both IMEIs are set to null and do not get reinstated even by MTKDroid tools...Any ideas ???
[Android General] csns:
Can you give more details on the MTKDroid tools?

Any error messages?

What version of MTK do you use? I think the latest is 2.30.
[Android General] makbro:
Thanx for the reply...I used MTKDroid tools 2.2.8...No errors, all the system info is displayed...Both IMEIs appear as null and cannot be restored !!!
[Android General] csns:
There is only one thing I can do: go back to stock and see how it works for me.. :)

But before I do that I need to ask you: how did you go back to stock? :) Did you flash the original boot.img via Flash Tool?

If YES then can you please share the boot.img that you used - as I mentioned mine is screwed up.

Thnaks!
[Android General] makbro:
I cooked my stock ROM using Android kitchen using my original "boot.img" and "system.img" files...The problem seems to be that I cannot exactly pinpoint the mount points for the "edify_defs" so that a correct "updater-script" is built...As of now only /system, /data, /cache are being flashed and the boot.img is not (since I don't know the original mount point for this and have not included in the script)...Also I am not able to flash only boot.img using flashtool...

Any ideas how to find the mount point for "boot.img" ??? Thanx
[Android General] csns:
hmm... why don't you try flashing the boot.img alone with SP Flash Tool? Like I wrote before the scatter loading file has the correct "mount point".
[Android General] pemergency:
Yes just go to your connection settings and edit your access point... all you need to do is removing a username and password from settings for your connection....
[Android General] xkikinx:
thanks for trying helping me out!
[Android General] makbro:
I don't have the original scatter file, so don't know the mount point for "boot.img" in the stock ROM...The scatter files I have are for the Chinese ROM and Foxtrot, using these mount points is not helping either !!!
[Android General] csns:
So I hope someone with a stock ROM on the exactly same model can generate a scatter loading file with MTK Droid Tools.

Otherwise... :(
[Android General] makbro:
I got the original mount points from entering "Android Engineering Mode" and made a correct updater-script, still doesn't work !!!

I get everything working but the Baseband is not recognized and IMEIs are set to null...I give up !!! :(
[Android General] berriosb:
I try to reset the acces point but dont meet where is that because dont meet when i write an username or password. I try to activate the function of data but all activated but dont have internet by sim data service but i have normal call service.

Hello friends and thanks for your support, yesterday I got all my 512 Mb of internal memory full, so I create an ext2 partition in my sd card in order to use link2sd. I successfully link my apps and get more space to install apps. The problem came up when I turned off my tablet and then turned on, my apps dessapeared and I had to install them again. What should I do? Try another app instead of link2sd? What do you suggest me.

Need info on warranty.

Hi guys... Thanks for support

I just bought this and want to know if i root and install new ROM, then also i will have warranty of my tablet?

Please suggest me any process to root the device and i don't have to avoid the warranty of my tablet.

I am from INDIA so do the calling will work.

Thanks in advance.
[Android General] makbro:
About warranty

Your warranty expires if you even do rooting and they find out, of course there are ways to un-root but can't be sure un-rooting is without trace...If you install any of these modded ROMs, you would be stuck with them and there goes your warranty !!!

As for installing the new ROMs, don't do it till you have a verified Nandroid back-up of your phone, preferably using "MTK Droid Tools" with "Temporary Root" option...

BTW we would be really obliged if you upload your Stock ROM, or even "boot.img" and "system.img" so that people like us who have installed these modded ROMs can revert back to Stock when needed...

Thanx

How can i unroot the tablet ?

I have added the MTK Droid Tools I use as an attachment...Follow these steps to make your full backup :-

1. Install the USB VCOM drivers for this device as instructed in the Word document attached

2. Set your device for "USB Debugging Mode" from the "Developer options" section under "Settings"

3. Connect your device to PC using USB cable, it will be initially connected as "USB device", tap on the notification for this select connect as "Media Device".

4. Start unzip MTK Droid tools folder wherever you want and run "MTK Droid Tools.exe", give it time (normally just 2-3 seconds), it will detect your device and display all information on the left section

5. Select "root, backup, recovery" tab in the MTK Droid Tools, check the box "Backup userdata and cache" and then press "Backup" button. If it asks for Root Access, just press "superuser" button before pressing "Backup"

6. It will make a full Nandroid backup of your device under the subfolder "backups" of the extracted MTK Droid Tools main folder

7. Click OK on "Pack backup" notification once backup is completed, it will zip the backup, it's not necessary though but safe to do it !!!

There you have it, your full Nandroid backup...Once completed, pl upload it and provide links...Hope this helps :)

[Android General] makbro:
Sure, you may or may not loose root, depending on whether the update is patching system files or formatting and reinstalling them...In any case, you can root again after update :)

Good news !!! I have obtained the ORIGINAL scatter file for my device...Turns out, it was sitting as "Firmware.info" in the full ROM dump I created using "Gscript Lite" before installing modded ROMs...The ROM dump also included all the required .img files for flashing with SP Flash tool...

The mount points are totally different in these modded ROMS, that is why restoring stock ROM through CWM recovery alone was not working !!!

Going to Flash the stock ROM tomorrow by Flash tool and will post results :):

not connect on 3g only on edge

Hi guys

I installed Pemergency rom but when i used my sim data card only reconize edge signal y never have 3g signal. I tried to modifier the configuracion but only there are signal 2g but no there arent 3g signal. In my location before install the rom my tablet was in 3g. Its have a solution? maybe an update for the rom?.

Thanks in advance.

I have installed pemergency rom,.. and foxtrot rom, from the russian website.

I can't get the 3g-data working. The settings are checked and doublechecked, but it won't connect

second, i keep on missing calls on this tablet. LOTS and LOTS of missed calls (the network answer is "phone off")

to solve this problem,... does anyone have the stock rom? or maybe available options?

Hi!

I have a problem when follow the steps it says the word. When I keep "vol +" pushed while pluging in the USB cable, my computer will not let me choose to install manually and device manager does not see any device. How to fix this problem?

I want to install drivers for root, because when I start the application "root.bar" appear the message "device not found". I don´t know what to do.

[Android General] makbro:
Probable solution for 3G data

I think I have figured out the problem that you two have...It's just that all of us who have working 3G data started off modding by flashing the chinese stock ROM using SP Flash tool...If you look carefully, it has a .img file named "fat_3g_16g.img"...Now look in the "scatter.txt" file, it DOESN"T say "NO__DL_" for FAT so basically this image will be installed...that's why we have a working 3G data connection...

In case of Foxtrot SP Flash ROM, there is "NO__DL_" before flash BUT there is no "fat.img" file in the folder, so that area is being formatted and nulled...That's why you don't have a working 3G data connection I think...

So the solution is first flash the chinese stock ROM using Flash tool as described in the original Chinese forum...There is a "How to.doc" in the archive...Then flash either Foxtrot or pemergency ROM and you would hopefully get a working 3G !!!

pemergency is the expert here...pl correct me if I am wrong :)

---------- Post added at 11:28 PM ---------- Previous post was at 11:12 PM ----------

If you want to just root, you can first install ADB.net...It will install drivers necessary for root.bat and also MTK Droid Tools...Later for SP Flash tool, you can remove the earlier drivers from device manager and install USB VCOM drivers or ADB SDK, whichever you prefer

Couple Questions

1.) Has anyone tried installing CoD tweaks on this thing? I have 2 A2107A-F tablets and they become extremly unstable after minimal use. I see it uses up every bit of RAM, I would just like to try and help this thing out a little.

2.) What is the exact hardware this Tablet is using, kinda curious to find out if there is a similar device that has been well developed that will have things compatible for this
