A fresh new plea....

Greetings...

I've done my requisite research and have found many "could be" solutions, but a post in here as recently as a couple of days ago referenced a couple of defunct links so I just want to be sure I'm doing things properly...

Though not knowledgeable enough to do these sorts of things myself, I'm excellent at following directions and have successfully rooted multiple devices....to include the very device I'm asking about right now....

2 Lenovo IdeaTabs: Both 2107A-F, Android Version 4.0.3, Build Number A2107A-F_S496_130221

1 is rooted, the other doesn't appear to be (no SU)....(I thought I had done both at the same time but apparently not)...everything was fine....then with the unrooted one I had the following happen....

At some point I started noticing the "Optimizing applications" at startup...

- My reading indicates this is a function of an OTH update...the rooted one didn't get it presumably?

Then the headphone jack mysteriously stopped working...(no trauma, really, really seems like a software issue given the couple of times I've gotten it back online)

- Some reading indicated this, too, might have been an update issue so I reset to factory settings (though I know that doesn't reset the firmware)...and oddly enough, it worked just fine....but then it quit again, with no rhyme or reason....

In further investigating the headphones, I realized it hadn't been rooted so I plugged it into the PC to do so....USB charges but doesn't initiate "USB Mass Storage"...

- The other device plugs in just fine and everything is normal but this one doesn't want to hear it....

So...

I'm pleading for some help...I've found enough info to try this or that but based on the knowledge base I'm seeing here this is something someone here is familiar with...my guess is that I need to flash the Firmware, root, and then perhaps install a custom ROM...perhaps on both...

I dunno, just need some help and I know many of you are much smarter at this than I....

I've verified that every setting is identical between the two, tried different cables...etc. etc...The troubleshooting I've done, coupled with this and a few other threads, seems to indicate a software issue...

Thanks much!

Dan

Thanks a lot for the reply. No, i havent solve it yet. Been away but im back.

Btw, there is also a reply by "priyanga" (thanks priyanga! :o) to startover but since mine is semi-bricked i cannot do the 1st step of backup.

Any suggestion?

Thanks for the help guys!!!

Many many thanks!!!!!!!

I repeat from scratch and

AT LONG LAST!!!! I WAS ABLE TO GET IT WORKING!!!!

THANK YOU SO MUCH... SYSERR!!!

THANK YOU SO MUCH... SVERZA

Also, maybe this version will not work properly SP_Flash_Tool_v3.1316.0.150 and i was forced to use this version SP_Flash_Tool_v3.1224.01 and it worked great! I used the foxtrot100 rom & files.

I am testing it now, i dont know if SIM1&2 is working (im looking for 2 SIM -only have micro). It has radio, camera, bluetooth, wifi are all working. Skype work well. Very, very HAPPY!

Also, THANK YOU SO MUCH... PRIYANGA

and THANK YOU ALL! (sorry if missed some names)

MANY THANKS XDA-DEVELOPERS!!! GOD BLESS YOU ALL

Great to be in this forum! THE BEST!!!

I hope the 2 SIMS work!! If not, please suggest (dont want to repeat that mistake again -hehehehe:D).

I tested the 2 SIM slot and i was able to call and send/received sms haven't tried 3G yet but still HAPPY DAY!!!!!

(i have my nvram backup so IMEI was the same as the original as indicated in the barcode)

Btw, the language is russian when i booted for the 1st time. So i change it but the dialer pad still has the russian characters. How do you remove or change it. No luck with the setting. Any ideas?

Thanks for all the HELP IN ADVANCE!! ...HAPPY DAY ...OH... HAPPY... DAY....:victory:

I think you can't remove it. I still have the russian characters (but also latin characters). In my opinion is a minor "issue" and never I went deeply to try changing it

Hi guys,

I have a Lenovo Ideatab a2107a-F version. It just like stopped working. Won't turn on. Can't get to recovery. But when I plug it into my computer, I hear the ding noise that it detected a device.

Is there a way to bring this thing back to life? Its for my little brother. I've tried using the SP Flash tool and that just never works. I'm not sure what to do. Can someone help please?

Thank you. Kevin147.
[Android General] syserr:
"It just like stopped working. Won't turn on."

The very first thing to do is hit the reset button... it kills power when it's hung.

Slide the back plate off. Below the camera there is a reset hole, tap that with a pen.

Now, press the power button for 3 seconds and release. Does it turn on? 90% of the time, this is all that is needed
[Android General] Kevin147:
I've literally tried that so many times. I'm the 10% that it won't do absolutely anything. I've tried the reset button, tried putting it in recovery mode, meta mode, everything. I don't get a response at all, it doesn't even show a Lenovo logo. Just a black screen no matter what I do.

Its really random and that's what I don't understand.... all of a sudden, it just stops. The only response that I get is when I plug it into the computer and my computer will play the usb connect notification, and the usb disconnect notification.
[Android General] syserr:
So, you never see anything but a black screen.... ever at this point? No matter what you try? When you say random... do you mean no reason for any of this to begin happening? or do you mean you get random behavior?

Tap the reset button. Plug it into USB power, not a computer. Check back in 30 minutes. Tap Power Button, do you see the battery screen charging?
[Android General] Kevin147:
All I ever see is a black screen no matter what I do. And yes - what I mean by random is I don't understand why this just began to happen. It was working perfectly before.

I just tried this. I do not see a battery charging screen. Still black screen.
[Android General] green2013:
Thanks for the reply :). REALLY APPRECIATE THE EFFORT!

Though it is a minor problem, I hope to see a solution. I tried to install different dialer, change language but still no luck.

BTW, 3G WORKS!!! Thanks ALL!!! Thanks XDA community :)!!!

Thanks ALL!!! Thanks XDA community :)!!!

advice

Is this tab running in original stock rom or you try to install any custom rom?
[Android General] Kevin147:
I had clockworkmod on it but it never booted into it so its still on stock, rooted.
[Android General] ssenemosewa:
I had a similar situation with my A2107A-F a while back. I managed to bring it back to life by pressing and holding the reset button on the back of the tablet for about a minute while also holding down the power button at the same time.

Pushing the reset button disconnects the battery from the tablet. I'm guessing that holding down the power button at the same time drains any residual power going to the board, allowing it to reset somehow.

If the tablet still doesn't show any signs of life, then you may want to examine the USB connector at the top of the tablet for dirt and/or pin damage. My intuition tells me that the tablet is not receiving power to the pins required to charge the battery...but the data pins are aligned enough for the computer to detect that something was connected to it.

Language question

Hi, I bought the A2107A-F for my father in law who lives in Rio De Janeiro

When he opened it and asked me to put it in Portuguese i was shocked

that it was not an option. I called Levono tech support and they told me to

buy another tablet in Brazil !!! Can I add a language pack to this, or if i flash

the European ROM will it have Portuguese ? I also read in the thread that flashing

the H ROM to an F tablet will make it very slow. Any assistance will be appreciated.

Thanks

What is the problem???

Your device is in factory mode...Follow the procedure below :-

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. Back-up the folder "\data\nvram" from your device to your PC...If not possible, at least note both your IMEI numbers that can be restored later using MTK Droid Tools...

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

(a) One of the two custom ROMs (with calling function and FM Radio) below (preferably Foxtrot v100) :-

(i) Foxtrot v100 : http://narod.ru/disk/64555789001.e72...t_100.rar.html

(ii) Chinese : http://dl01.chinapader.com/ROM/A2107A_H_S121_120525.zip

(b) SP Flash Tool v3.1216.02 here : http://xdaforums.com/atta...3&d=1360162416

(c) USB VCOM drivers here : http://xdaforums.com/atta...4&d=1360162416

(d) USB Driver installation here : http://xdaforums.com/atta...5&d=1360162416

3. If you haven't already, install the ADB drivers to your PC downloaded in step 2(c) as per "How to.doc" downloaded in step 2(d)...

4. If your device is 16GB, skip this step...If your device is 4GB or 8GB, browse to ROM folder (downloaded and extracted in step 2(a))... 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...

5. Make sure device is not connected to PC and is powered-off...Run SP Flash Tool "Flash_Tool.exe" downloaded in step 2(b), click on "Scatter-loading" button, browse to the ROM folder (downloaded and extracted in step 2(a)) and select file "MT6575_Android_scatter_emmc.txt" (the same file that you edited in step 4 if your device is 4GB or 8GB)...

6. Check the box "DA/ DL all with checksum" and click "Download" from main menu of Flash Tool...Now 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 (reset button location is shown in a pic inside the "How to" doc you downloaded in step 2(d))...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 with "Download OK" indication...remove usb cable.

7. Power-On the device...You have installed the new ROM...whait for 1 to 3 minuites

[Android General] syserr:
Ed,

Yeah, you don't want to flash the -H ROMs to a -F, unless you can figure out what makes it slow. I believe the -F was only marketed in the US, and I only know of one ROM (family). The only thing left would be figuring out how to port Portuguese to the -F ROM that pretty all -F users have.

It's sad to say, but the value of this tablet is $60 or below now. It may be worth getting a different tablet. If you really think this is what you want, I'll look into it.

You need to do lots of reading. The FAQ and ROM links in my signature are helpful. The AT&T ROM that you mention is a CWM-style ROM. You have to get Clock Work Mod installed before you can use it. But also, the AT&T ROM seems to break 3G/DATA on dual SIM -H models, so do you really want to do this in the first place?

Hey :)Tons of useful inferomations in this thread, helped me lots. :)

Sadly, I find myself in a bit of a stupid situation - while fiddling with my a2107a-h, i deleted some .apk from the system folder with root explorer.

I was smart enough to make a CWR 6.01.5 backup that same day. But when I used the recovery option in CWR the device booted, went though the boot animation and stuck in the lenovo splash screen. I waited for a while (30 min) but nothing happened.

Then i wiped the data to factory setings, hoping for the best. The device booted (as in out-of the box) but when i tried to unlock it it froze in a blurry way.

Can you guys tell me what to do, because I`m seriously lost here.
[Android General] priyanga:

[Android General] leobuf:
I think the backup was not complete so the restore doesn't work properly. Take a look to other ROMs are really great!
[Android General] Kiretza:
I read a few guides on how to flash with SP tools, and yet I still am unable to. I have the scatter file, generated with MTK droid tool, I have the zip file for foxtrot (downloaded from here for my device). There must be something I`m missing. I also tried installing the zip with CWR, but that didn`t work either.

BTW I used the same restore before that and it worked. Don`t know if it really matters though.

[Android General] syserr:
Nope, it looks like I haven't uploaded it. (shame on me)

I purchased one about 4 months ago in hopes that it would help piece together the whole A2107A family. The Vodaphone Smart Tab II I purchased is from UK. I stripped it down and found it was much like the AT&T ROM. One big difference is it has a FAC partition like the A2107A-F.

I'll upload it ~12 hours from now. I have a SPFT rip and also I apparently I made a "SE-SRS" (syserr rooted and scrubbed) version in CWM-style ROM. The trick is because of different partitioning, you can't throw a stock VOD rom on say a generic -H without an SPFT reformat with the VOD scatter file.
[Android General] sverza:
In fact. I have the Vodafone version (4GB, 1 sim) that had the stock rom.

I tried to flash a ROM simply with the recovery modified but with no positive results (stucked on Lenovo logo or reboot issue). I had to flash with SPFLASHTOOL the stock 4GB ROM (no brand) and then I was able to flash another ROM "simply" with recovery modified.

Before flashing the tablet I did a dump of stock Vodafone rom with MTKDROIDTOOLS and then made it compatible with SPFLASHTOOL (just in case something went wrong). Well, everything was ok BUT one night I deleted the dump!!!

I wait for your upload

[Android General] ssenemosewa:
Can you share what those minor changes are? I'm curious how it stacks up to what I'm using.

I'm currently using what I refer to as a "Frankenstein ROM." Basically, it's a mixture of Syserr's SE_SRS_A2107A-F_S486_130221-signed.zip ROM and the kernel from Shiloh's A2107A-F_S483_121115.zip ROM.

Why the hodgepodge? Well, Syserr's ROM works great except for one thing: The kernel he used shuts down the tablet almost immediately when it feels it's overheating. Normally a great safety feature...except when you have a temperature sensor that's a bit goofy like in my A2107A-F: It tends to fluctuate all over the place. Hit the upper limit and wham: Syserr's ROM shuts the tablet off.

For whatever reason, the kernel in Shiloh's ROM warns of the over temperature condition but allows you to dismiss it without the tablet just shutting down on me.

What you need to understand, not only do you need to adjust the scatter file, but MBR, EBR1, and EBR2 need to be adjusted to match. I have a script that does this. If you have the original scatter file and ask me to adjust it, I will. Be warned though, about half the people get disintersted when they find the DATA/USRDATA partition can't be over 2GB-- it's a limitation of MediaTek at least during this time period.

So, the only way to resize parttions seems to be flashing using SPFT. Not recovery (CWM or TWRP), right?

Sorry for the question, do you currently use different sizes than the original?

And in this case will you generate a new scatter file + MBR + EBR1 + EBR2?

It seems to be the "upgrade" of the A2107.

If Lenovo has used the same "process" as A2107 (and various 4-8-16gb) maybe this recovery could be ok also for A1000...

It also true there aren't so many custom ROM (at the moment) for the A3000 series
