We wait for an solution.

Thanks makbro.
[Android General] makbro:
Your device is in Factory Mode, one of the images, most probably "system.img" was incomplete/ corrupt when it was made by MTK Droid Tools...

Now you can flash CWM Recovery again (if required) and try to install the CWM Flashable Nandroid back-up created by MTK Droid Tools...It would be inside the back-up folder created by MTK Droid Tools in another folder named as the date and time it was created...(Look for a subfolder in the MTK Droid Tool back-up folder with files "system.ext4.tar", "data.ext4.tar", "cache.ext4.tar", "boot.img" and "recovery.img")

In case that doesn't work out, you can flash the Stock ROM that I have posted here : http://xdaforums.com/showpost.php?p=37570061&postcount=868

[Android General] makbro:
Will give it a try !!!
[Android General] makbro:
Remember, you have to read and carefully follow all steps, one by one as I have listed below, otherwise, you may brick/ damage your device

1. IMPORTANT...Copy the folder "\data\nvram" from your device to your PC...If not possible, copy this folder to the external SD card in your device...

2. Download and extract the following in one global folder in your PC :-

(a) The Stock ROM I posted here (two parts) : http://xdaforums.com/showpost.php?p=37570061&postcount=868

(b) SP Flash Tool v3.1216.02 attached with this post

(c) USB VCOM drivers attached with this post

(d) USB Driver installation "How to" guide .doc attached with this post

3. 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...

4. Make sure device is not connected to PC and is powered-off...Run SP Flash Tool "Flash_Tool.exe", click on "Scatter-loading" button, browse to the Stock ROM folder (downloaded and extracted in step 2) and select file "MT6575_Android_scatter_emmc.txt"...

5. Select "Format" from Flash Tool menu and then "Auto format whole NAND Flash" and click OK to format device...Now keep the "Reset" button of the device pressed while plugging in the USB cable to your PC and release the Reset button once cable is plugged-in (reset button location is shown in a pic inside the "How to" doc you downloaded in step 2)...A big green circle appears with "Format OK" indication...Disconnect device from PC...

6. After format, check the box "DA/ DL all with checksum" and click "Download" from main menu of Flash Tool...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...This will take approximately 13 minutes with 7-8 different color bars completing 100% progress...Don't do anything until the big green circle appears again with "Download OK" indication...

7. Power-On the device...You have Stock ROM restored...Now delete the folder "\data\nvram" from your device and copy the folder you backed-up in step 1 to the same location in your device...

There you have it, an out-of-the-box device !!!

booting to CWM

Hello

I was following the topic to proceed for rooting and installing custom ROM.

well successfully rooted, and installed ROM with CWM after finishing installation, every time device is booting, its going to CWM,

any suggestion?

i used LeWa rom :)
[Android General] tikkesang:
No Screen

I think I messed Up every thing, No screen, Just plug in sound to PC which shows device is alive !

I tried to use flash tools with my own back up but no success.

makbro

Thanks for what you have done for this topic

This file is not included in your ROM files . MT6575_Android_scatter_emmc.txt

I tried my own, but i don't know which option or img i have to tick or load in flash tools panel for format or back up ! .

let c if you can help me to get back the device alive ! or just i have to forget my tablet totally ;)
[Android General] makbro:
The file is present in the SP FLASH TOOL VERSION OF STOCK ROM that I posted here : http://xdaforums.com/showpost.php?p=37570061&postcount=868 ... I have re-checked !!!

You must be looking inside the CWM Flashable Stock ROM that I posted earlier !!!
[Android General] Camborg80-Trey:
Hey Makbro, so here's where I'm at right now.

That F-model thing garingam posted up earlier is for the F-model (I confirmed it), problem is, I have no idea what to do with the files once I download them. CWM (both versions) could not install the file, and if these are compatible with SP Flash tool, I'm in the dark as to what to check in the boxes when I load the scatter file in sp-flash). In fact I have no idea what to do with the .zip file i get after downloading it from Google Drive (it's what he uploaded it to).

I was able to get cwm on the tablet (while I had the H-firmware installed just to get the thing to boot. I got that from the post posted earlier that had the "skymod" folder. I guess this was stock european H model firmware. I used SP Flash and it worked).

Anyways, and I'm referencing the stock F-model compatible-cwm file you posted for D that he was kind enough to re-upload for me, I installed it successfully (had to use the latest version of CWM, old version wouldn't work).

It said it succeeded without problems, yet after I rebooted I am now stuck at the first Lenovo screen and it will not advance past.

What am I doing wrong? What else can I do? I'm at my wit's end and about to chalk this up to a $150 loss.

If I could just find a stock, F-model firmware that FULLY WORKS WITH SP FLASH TOOLS I'd be all set, good to go. But I can't. And using CWM isn't helping either.

Please, can you or anyone offer me any help? I just want to get the stock F firmware back on this thing :(

Here's what I did in regards to garingm's upload of the F-model zip...

I unzipped all files, and tried using two different versions of SP Flash on them

Here's the error I get when trying to use SP_Flash_Tool_v3.1206.01:

Here's the error I get when trying to use SP_Flash_Tool_v3.1224.01:

I'm wondering if the errors are resulting from an improper DA file (Download Agent). I tried using all the available ones I found in the folder garignm put up, and I get an error for each of them saying they are not proper DA files. Here is what was included in his upload that are listed as .bin files:

I'm wondering if perhaps I can get over the DA file thing this might work! (or perhaps I'm off altogether).

Like I said, SP Flash isn't giving me any help and CWM did the 'update' but device won't boot past first lenovo logo.

I think maybe I need a Flash Tool version that is completely set up to work with garingm's upload? MAYBE THAT'S THE ANSWER! Problem is, it's something I can't do on my own :(

I'm desperate guys...if you can, please please please help! :(
[Android General] makbro:
Use the SP Flash Tool version v3.1216.02 that I have posted here : http://xdaforums.com/attachment.php?attachmentid=1708563&d=1360162416

This will remove the error "incorrect scatter file"...Also read the instructions for flashing thru this tool (step 3 to 7 of this post : http://xdaforums.com/showpost.php?p=37660076&postcount=890)

To confirm what all files you need for flashing thru SP Flash Tool, look at this post : http://xdaforums.com/showpost.php?p=37579773&postcount=871

My Bad !

Don't know y whole the night i was working n couldn't c the file ! :))

Well after 40 hours being awake it could happen. i will try to root again and restore my nvram .. and again i will try to install custom ROM.
[Android General] Camborg80-Trey:
No go...

I downloaded and ran the SP Flash Tool you just provided from the link. As soon as I open it and try to open the MT6575_Android_scatter_emmc.txt that is in Garignm's folder (For the F-model), I get this error:

I thought I was so close :(
[Android General] makbro:
There must be something wrong with the scatter file then...Post the scatter file in the garringm back-up, I'll have a look !!!

And also try re-downloading the Flash Tool, sometimes a corrupted download also creates errors !!!
[Android General] brickedstone:
Dear Makbro,

First of all, thank you loads and loads for your kindest possible support. I am an absolute newbie to Android, in fact tablets, and would like to ask a few buggers in my mind after reading almost all the posts:

- I understand as a 4gb device holder I have to use the flash tool because CWM backups shared here would create storage problems on my device.

- What is the difference if I use

rom dump from my own device (let us say I manage it somehow)

or

from your stock for SP flash

and use them in Android kitchen to create a CWM restore image that works on 4gb device? I actually had a brief look at the kitchen's menu and it seemed disinterested in questions related to storage capacity. Apparently, boot.img and system.img that it takes contains all the information it needs. But are these two files found in the stock ROM you shared (for SP flash) different from those that I would obtain from the ROM dump of my tablet?

- I remember running a backup script in GScript for flashing CWM recovery. Can it be that the boot.img and system.img of my device are already there and I can use them straightaway in the kitchen?

The point is that using SP flash tool appears cumbersome with all the reset button issues and CWM appears to be the most natural and seemless way of doing stuff.

Thank you once again for all the help you provide. Really cannot appreciate in words :)
[Android General] makbro:
I came across another "modem.img" for European Region so I cooked the LeWa modded version with this...Try it to see if 3G starts working...

EDIT : This modem.img also didn't work, so I took it off !!!

And also try the updated modded ROMs that I have re-uploaded today, I added some tweaks to boost, media, system and 3G performance further (for all modded ones), may be that resolves the problem with 3G !!!
[Android General] Camborg80-Trey:
Here is a link to the scatter file:

http://www46.zippyshare.com/v/15157026/file.html

Thanks again for all your help...I really appreciate it! I have a feeling if I can get this stupid thing to play nice with the Flash Tool I'll finally be good to go.

Tried re-downloading zip file for SP Flash, still same error.

If it's not too much trouble...do you think you could download garingams' image and play around with it to get it fully working? Or if the scatter file will be enough (you think), then tool with that and tell me what to fix or re-upload?

Thank you a million times :)
[Android General] makbro:
If you have read almost all the posts in this thread, you already know that I also have a 4GB device...This means all the CWM Flashable ROMs that I have cooked are from the 4GB version...

Moreover, CWM Flashable ROMs don't mess-up your storage capacity info...It's the SP Flash Tool ROMs, in case you flash the wrong "fat.img" file...That's why I have posted to change the "FAT...." field to "__NODL_FAT...." field in the scatter file before flashing thru SP Flash Tool...

From kitchen, you can cook an "update.zip" type ROM which is installed thru "Install zip from sdcard" option of CWM, not the Restore option, as are all my cooked ROMs...And yes, the kitchen uses only "boot.img" and "system.img" to cook ROMs...The ROMs cooked there are CWM flashable, so no issues with memory...

In case of my ROMs, if you put any of my .zip ROM file (un-extracted) in the "original update" folder of kitchen, it will automatically extract the "boot.img" and "\system" folder in the working folder to begin customizations...In case of the SP Flash Tool version of ROMs, you have to unzip/ unrar the archive and you'll find "boot.img" and "system.img" inside, along with many other images...

Your back-up with Gscript will contain both ROMs...SP Flash Tool version in the root of the "backup v2" folder and CWM Restore version in a sub-folder named "BDRS.........", the "..........s" being the date and time back-up was created...

The difference between a CWM Restorable ROM and the "Install zip from sdcard" one is the latter does not contain data and cache whereas the earlier restores complete ROM including "data" and "cache"...

So to sum it up, you can use any of my posted ROMs (except the SP Flash Tool one) to flash thru CWM Recovery OR you can use the "system.img" and "boot.img" from your Gscript back-up to cook a .zip from Kitchen OR you can use the "BDRS......" folder and Restore your ROM completely (including data and cache) from CWM Recovery...

[Android General] Camborg80-Trey:
Sorry about that, here's the link:
[Android General] brickedstone:
Thanks for the wonderful explanation. Actually it is a huge thread already and I just mixed things up. Of course your CWM ROMs should be usable off-hand. That should solve all the immediate problems and should proceed to play around with the moddded stuff. I will nevertheless look into the doabilities afforded by the kitchen. It is quite intriguing to know everything :)
[Android General] makbro:
Use this scatter file, I've checked it, it loads trouble-free with the SP Flash Tool version I suggested to use :)

LeWa Feedback

Well Finally I've Done it, Now I am alive with LeWa ROM.

First of all many and special thanks again to makbro. words are not enough to thank you.

My feedback from LeWa ROM:

1- Very Smooth and fast comparing original ROM

2- Wifi Working perfect

3- very low memory usage

4-3G working fine for me

5- both Sims are ok and working

6-Application till now is working fine

7-both sms and Call are fine

8-input language is ok and i can use another language using applications

....

the most that is bothering is the UI, it is base on cell phone UI and not the tablets . so the fonts are bigger and menu's looks big a little .

will w8 for an update.

some time while booting a some flickr of screen (very rare ) could be seen.

...

thats all for now . will give you an update in case !

...............

makbro

all links of ROMs you've uploaded are gone and no file could be downloaded from the links. would u check whats wrong ?

....
[Android General] Camborg80-Trey:
Perfect! It actually loads it! :D

Problem is...no boxes are checked and I have no idea what needs to be checked and what doesn't, as well as what corresponding files to assign to each box.

I tried to look at the screen captures you put up for me a couple pages back and they're too small to legibly see for me. Also, it doesn't really give me the exact info as to what file to assign to each checkbox.

Do you perhaps have a list I could go off of or anything?

We're standing on the edge of it working...once it successfully flashes we're in! Please stick with me sir and thank you again! :D
[Android General] makbro:
There was an issue with the Dev-Host servers, I have updated the links to all modded ROMs in my post : http://xdaforums.com/showpost.php?p=37409096&postcount=800...

The big UI of LeWa is the unique signature of all LeWa ROMs...Some like it, some don't...Changing it requires expertise I don't currently possess ;) About the screen Flickr, see if you have disabled the Quick Boot option or not from "Settings"--->"Accesibility"---->"Quick boot" (just un-check the quick boot box)...

I have also added a few more tweaks to boost system, display and 3G performance in the newly uploaded modded ROMs !!!

FALSE ALARM! :(

I originally loaded the scatter file while it was in my desktop, and not in the folder with the rest of Garignam's backup.

I put it in there, opened your sp flash tool version, and tried to open the scatter file and get this:

I'm so mad I just can't figure out what the hell is going on anymore. Perhaps it's a problem with Garngnam's upload? Hell if I know.

This is getting crazy.

Why...can't I just get the stupid firmware for F flashed onto this! Sigh. :(
[Android General] makbro:
Well, I already told you the list of files in this post : http://xdaforums.com/showpost.php?p=37567429&postcount=867

Also if you click on the thumbnails attached in the post, the pics will open quite large and legible ;)

EDIT : I read your FALSE ALARM post just now...No error outside and error inside clearly shows something wrong with garringm back-up images either originally or may be a corruption during upload by him OR download by you !!!

Do you happen to have Team Viewer with you??? I can take a look at what's wrong thru that, it would be faster and time saving for me !!!

Re online-backup

Hi thunder.

Easyest way to geth the boot and recovery images its open a termainal or adb shell and using the command :

dd if=/dev/bootimg of=boot.img bs=6291456c count=1 2>/dev/null

dd if=/dev/recovery of=recovery.img bs=6291456c count=1 2>/dev/null

You geth both and coppy them to Your Nanroid backup folder. Delet the nandroid.md5 and do a new one with the command :

md5sum *.* > nandroid.md5

After that its very easy too install the compleet backup with CWM :)

Normaly You also have the original images in the backup from the GScript, its only to copy them too Your backup and do a new md5 checksum. Also posible taking the boot images from the zip you have installing the system with CWM ;)

Have trying difrent versions of CWM 5 and 6 and i cant geth enny good working backups only with the GScriptLite and online-backup nandroid.

The good thing I have never blowing the "/data/nvram" folder and messing the ID:s upp :cool:

Yes, I do! I'll be at work all day today though, and won't be home until tonight at around 8:45 PM (Pacific Standard Time).

Would that possibly work for you?

Please say yes! haha:cool:

I am in Eastern European Standard Time, that would be 04:45 AM for me...So I am sorry, that is not possible :( We have to decide on a time suitable for both of us :)

I am available between 08:30 to 10:30 and 19:00 to 22:00 (all EEST)...

Looks like our schedules will be pretty impossible to mesh over the next several days :(

I just wish I could figure it out...the h firmware flashes via sp flash tool flawlessly. If onlh I could find an F model version that would be the same -_-
[Android General] Camborg80-Trey:
I just came up with a perfect plan!

I'll go to the store and buy a brand new lenovo ideatab a2107-f, download the stock firmware off of it, and FLASH IT ONTO MY CURRENT F MODEL!

What do you think Makbro? That should work, right? Only problem is, I have no idea how exactly to do that and what toola I'll need.

Basically, I need to pull the firmware off the new model and use sp flash to put it onto my currently screwed-up device. Do any of you think this is possible? And if so, could a kind soul give me step by step instructions on how to go about thia?

Thank you so much :)
[Android General] Contra1971:
it does, how to I access the tuner?

I have the a2107a-fdoes it have the tuner?
[Android General] makbro:
It would definitely work but why to go to such extreme step so soon (I am referring to spending another $150) ... There are many more things that you can try before giving-up ;)

Week-end is here, may be we can find some time (late at night/ early in the morning at your end so that +8 hrs is suitable for me too) ... I would just wish you would try to flash the A2107A-F CWM Recovery and then install the stock ROM I cooked for D !!!

---------- Post added at 09:08 AM ---------- Previous post was at 09:02 AM ----------

The device comes with FM Radio app pre-installed, if it's not there, install from Playstore...Then you can use the FM Radio with headsets only !!!

In case you want to use FM Radio without headsets, have to Root device, install CWM Recovery and then flash one of the custom modded ROMs I have posted : http://xdaforums.com/showpost.php?p=37409096&postcount=800

Before you do that, make a back-up of your app & data back-up using "Titanium Back-up" (after rooting) so that you can restore all your apps & data after installing custom ROM :)

Super fast GPS location fix

Yesterday, I stumbled upon a Russian forum with a 4 step procedure for super speeding up A2107A GPS location fix ... I carried out the required steps and results were astonishing, location fix (with all GPS cache clear) reduced from 10 minutes to 30 seconds...With cache (location already fixed once) location fix is almost instantaneous :)

So here is the procedure :-

1. Install the app "ClockSync" and choose the nearest ntp server in the settings (e.g. "eu.pool.ntp.org" for Europe)...Then sync with atomic time from app menu...

2. Install the app "FasterGPS", go to "Advanced Settings" from Menu and set the following :-

NTP_SERVER=eu.pool.ntp.org (Has to be the same one as in step 1 for ClockSync)

INTERMEDIATE_POS=0

ACCURACY_THRES=0

REPORT_POSITION_USE_SUPL_REFLOC=1

ENABLE_WIPER=1

SUPL_HOST=supl.google.com

SUPL_PORT=7276

SUPL_NO_SECURE_PORT=7276

SUPL_SECURE_PORT=7276

CURRENT_CARRIER=common

DEFAULT_AGPS_ENABLE=TRUE

DEFAULT_SSL_ENABLE=FALSE

DEFAULT_USER_PLANE=TRUE

Press "Save" to save settings to the file "gps.conf" (You can also manually edit "gps.conf", the app provides easy interface to edit the file)...

3. Go to "Settings"---> "Location services" and confirm following are checked :-

Google's Location Service

GPS Satellites

GPS EPO assistance

Location & Google Search

4. In the same settings menu as step 3, click on "EPO settings" and press "Download" to download the EPO data (you may also check "Auto download" after downloading EPO data to automatically keep the EPO data updated)...

5. Now open any GPS Status checking app (like GPS Status & Tools) and see the magic ;)

---------- Post added at 09:48 AM ---------- Previous post was at 09:26 AM ----------

If you are referring to "Any Radio" app, there is a button to "search" all channels (I think the button icon is a magnifying glass, can't be sure as I am running the LeWa ROM right now)...Once you press it, the app asks you whether to replace the existing channel list, just press "OK"...After the search is finished, all channels are saved in the channel list which you can access thru a button as well (I think it is the sign used for "bullets" in word or Excel, three dots, each followed by a line)

Once the channel list is prepared, you can subsequently add channels to your favorites list :)
