Yes, I shut down the SP Flash Tool because nothing happens... it stays in red...

Unless you are telling me that I should wait with this red progress bar for 12 minutes ?
[Android General] makbro:
No, not at all...In my case the Flashing continues till I get the green circle with 100% that you got in case of Foxtrot ROM...Try pressing the reset button again when the flashing stops after red with my back-up !!!
[Android General] csns:
Well pressing the reset button, unplugging and plugging in again does not have any effect.

Red bar is stuck in 100%, time keeps running and that's it.

Do you also get all the errors while loading preloader and dsp_bl ?
[Android General] makbro:
No, I don't get any errors...But I have noticed that even if I replace these two with the ones from Foxtrot or Chinese Stock, I still don't get any errors...May be you can also try that (Of course if you haven't already :) )
[Android General] csns:
If I use Foxtrot preloader and dsp_bl the whole process goes OK to the end... but the device gets stuck on the Lenovo logo when I try to boot it.
[Android General] makbro:
Well if it is the same with Chinese stock ROM preloader and dsp_bl, then I am out of ideas...sorry !!!

One more thing though...Have you tried the "boot.img", "preloader" and "dsp_bl" included within "CWM Firmware" folder by pemergency provided on page 5 of the thread ??? Rather try using all of his files, together with "system.img" and "data.img" from your original back up !!!
[Android General] csns:
Can you tell me what is the SP Flash Tool version that you are using? Perhaps that's the problem...
[Android General] makbro:
The one included in Chinese Stock ROM ... Pl read the updated part of my post above as well ... May be that will help :)
[Android General] csns:
I just tried the trick from your edited post - no luck - still freezes on Lenovo logo.

But coming back to the SP Flash Tool - can you provide the exact version number?

Thanks.
[Android General] lieutenant132:

[Android General] csns:
Thanks a lot but a STOCK rom is a rom that came unchanged from the manufacturer of a device - if it was modified (like in this case the calling feature enabled) it means it's NOT stock rom any more.

Thanks for the effort though.

[Android General] acanuckeh:
I followed your guide to root and put CMW on the tablet. I used mobileuncle and michfood to install cmw. The issue is, although I can boot into CMW from mobileuncle, I cannot boot into CMW recovery from the tablet being off. Every time I try, I just enter into android recovery...Am I missing something? I tried following your update 3 guide thinking that its a more 'permanent solution but cannot get it to work. It will give me an error after the purple bar is 100%.. Am I missing something? Do I have to unlock the bootloader to make the michfood method permanent?

The error I get is:

BROM ERROR: S_FT_NEED_DOWNLOAD_ALL_FAIL (4050)

Need download all images!

{hint}:

DA partial images download is only allowed under following prerquisties: 1. all images have been downloaded to target before, and target could boot up; 2. the images layout map on the target is the same as the load that is to be downloaded.

Thanks!
[Android General] makbro:
Did you switch your storage media back to Internal SD after you created a ROM dump with step 1-2 and before flashing recovery ???

Also check if you are using the correct scatter file and the recovery file from within the CWM recovery folder provided in update 3 ...

Hope this helps...
[Android General] acanuckeh:
There is no actual CWM recovery folder in the zip file...but I am pretty sure I am linked to the correct scatter file and other files that are located in the same folder.

I did switch over to SD, my unit has internal storage, plus and internal sd card and i have an external one.

Can't figure it out !

A2107A-F

Well what about the f/wifi only model any roms come on

or athing something any info help ect ??
[Android General] makbro:
In case you are not already using this method and this folder, pl try it :-

http://www.mediafire.com/download.php?fbuzi5xjofs7vgf

Above is the link to folder"A2107A-easy_CWM" installation, that is the CWM folder I referred to in my last post and the link is provided in Update 3...It has the instructions included along with 3 different recovery files that you can choose to Flash...1. Stock that you already have...2.CWM 5.5.0.4...3.CWM 6.0.1.5...

Choose whichever you like, personally I prefer CWM 5.5.0.4 cause 6.0.1.5 makes back-ups in a different way...
[Android General] acanuckeh:
Still no luck, same issue. I mean, I can boot into CWM from the OS w/ Mobileuncle tools, its just that I cant boot into CWM when the unit is off, it just loads into Android recovery. Thanks for the help though. Still looking for a solution though.

I notice that when I flash CWM w/ Moibleuncle tools, it will boot me into CWM, if I press the reset button i can manually boot into cwm, but if shut down from the os, then when i go to boot back into cwm from power up, it sends me to the android recovery. its like the flash erases from my system when ever i power down. any explanations?

PERHAPS RELATED?
[Android General] Gromph:
I've been trying to follow pemergency steps from post #45. Sp Flash Tool formatted successfully, but Smartphone Multiport would go to 100% on Com11 then say FR ERROR. Now my A2107A won't boot, nothing ever displays on the screen. I've read most of this thread and I tried most of the tricks mentioned.

Now I'm trying the A2107A-easy_CWM.7z, the post above mentions that instructions are included but I don't see any text documents in the archive.

Flash_tool does successfully format, but now what?

Thanks!
[Android General] makbro:
Hmm..there may be one thing, have you checked for the file "/system/reboot-from-recovery.p"...If it's there, either delete it or move it to some other place...This file restores the default recovery on system reboot !!!

performance increase

:laugh: so today I installed zeppelinrocks v6 supercharger on my kids tabs. What a major performance increase. http://xdaforums.com/showthread.php?t=991276 read the thread thoroughly if you need help or have questions pm me.

Major improvement on touch screen

Major improvement scrolling speeds

My son watched YouTube videos with no problems

I also downloaded spare parts from play store and set all animations to off.

Live wallpapers will cause the home launcher to be choppy, I'm looking into other alternatives for this

There was just major improvements all over you will be glad you installed this

---------- Post added at 10:09 PM ---------- Previous post was at 09:44 PM ----------

In addition another major improvement is to use another home launcher. 99% of the lag this device experiences is in the stock home launcher, after I installed nova or apex they were able to use live wallpapers with no lag. I'm still searching for a better solution
[Android General] manwithmanypiercings:
Have you tried holo hd?
[Android General] acanuckeh:
I just installed this aswell...Wow a great improvement! Which options are you using? Which install did you go with? I am using V6_SuperCharger_for_Android-Update9_RC10.sh.pdf

Thanks!

Also...

....worked for me !! Thanks so much :D
[Android General] garringm:
I don't remember exactly which one it was, I know it was a stand alone .pdf script from a post on that link, the latest I could find. I used the recommended OOM values, I also used that lag killer, not sure what it did though but I installed it, I did the misc tweaks on one and not the other, don't notice a difference between the two. I set one to use the V6 animations and one to not ??. I also did a dalvik-cache wipe and reboot as recommended by the script installer. Afterwards I set Script Manager to run the created .sh file at boot. The next biggest lag killer was getting rid of the stock launcher and replacing it with apex or nova, I'm still looking into other alternatives such as Holo Launcher HD as recommended.
[Android General] manwithmanypiercings:
I just use Holo because it's a small file. Just kept with it since the time I was running SlimBean on my SGH-i717.
[Android General] garringm:
I just had my son install it and he didn't like it. I installed it on my SG3 and like it. But to each his own. I'm gonna try pulling the launcher from my acer tonight see how that goes on his.

For anyone wnating to get rid of the Lag especially with the launcher and app drawer, as of right now it is Highly recommended to use one of these three launcher

Apex

Nova

Holo Launcher HD

I'll be sure to post any new tips or tricks as I find them to help this tablet along the way. I think we have made great progress so far.:good:
[Android General] lambofgod13:
I use apex on my evo, galaxy nexus, nexus 7 and my lenovo. It seems to work the best.
[Android General] garringm:
What was your take on using it over the stock launcher on the Lenovo tab, this needs to be shared so everyone knows
[Android General] D1358531:
Go Launcher works quite well too. :)

By the way, I haven't had a chance to read this entire thread, but is it possible to install just the CWM on the A2107A-F? I already have it rooted.

[Android General] lambofgod13:
I use apex over all stock launchers for the customization and its way more responsive and no lag. The issue with lag on this tablet is that the ram fills up what's bearly usable after the rom and apps that are on internal storage.

After years of using launchers ice find apex performs best, launchers like EX and Go launcher have to much integrated stuff that constantly runs in the background causing crappy battery life.

My A2107A-F is completely stuck on the second lenovo logo (right after the animation) It just stays there. It vibrates shortly, and that's it.

Happened after my first full shutdown after rooting it. (It was working just fine after the root)

Any ideas?

I can boot into android recovery mode.
[Android General] garringm:
First off did you do a backup during the rooting process. If you didn't you will need to try a factory reset through recovery. If that doesn't work you probly need to get the files to do a lot flaws with mtktool I know I posted a clean backup somewhere in the pages recently
[Android General] makbro:
If it vibrates shorty, it means the device is past the preloader and not in bootloop...Try waiting longer after it vibrates (may be upto 5 mins) to see if it completes the start-up...If not starting up then consider the lines below:-

Did you make a back-up before shutting it down after rooting ??? If yes you can flash CWM 5.5.0.4 recovery using "Update 3" procedure in this thread (credit csns) and restore your back-up :-

http://xdaforums.com/showthread.php?t=2044496

If you don't have a back-up, you can flash the clean back-up posted by garringm in this thread...

If that doesn't work too, the only option is to flash a custom ROM for A2107A-F (which I haven't been able to find as yet) ...Pl don't flash A2107A-H custom ROM to your device !!! All the custom ROMs mentioned in this thread are for A2107A-H not -F !!!
[Android General] garringm:
I've been looking into building a clean cwm flash able ROM for the -f
[Android General] makbro:
That would be great for the -F device holders in this thread cause there isn't any real support for this model as far as the custom ROMs are concerned...Since I don't have the device, I cannot test any customization I do on -H ROMs or try to port them to -F...

Just a suggestion for CWM flashable back-up, if you follow steps 1 and 2 of the thread by csns for back-up + root + cwm, the Gscript lite back-up that is created in "backup v2" folder has a subfolder in it named "BDRS...", the dots are the date and time of the back-up...This folder has a 100% working, personally verified CWM flashable ROM :)
[Android General] ilam3d:
I managed to get it to boot. After a few factory resets (i don't know why it needed a few) it booted into the 1st time setup promp. I managed to upgrade it to the latest firmware while on the OS. (The latest firmware really does speed this thing up, it's really snappy now)

It seems like the Desktop APP somehow got damaged, since it wasn't working when it booted up. That's probably what held it from booting up properly.

Thanks a lot for the help.

-------------------------

For -F users: Try to not mess with the integrated apks unless you really know what you're doing. There is no official firmware backup out there. (Unless someone figures out how to somehow get the official firmware upgrade file that's downloaded from lenovo)

**** DO NOT PUT -H ROMS INTO -F TABLETS ****

This did not work for me. I still only ever get to android recovery and not CWM from power down using the button presses! This is very frustrating :(

The file was there and I renamed it and moved it to root. I can only ever get to CWM via mobileuncle. Perhaps the lastest OTA breaks this functionality.

[Android General] garringm:
Any chance you can put that file up for download somewhere?
[Android General] D1358531:
I would, but the file is 448MB...I have a mediafire account, but I can't upload anything over 200MB...any free services that will allow this file?

I'm trying to upload the file to my Dropbox folder. Hopefully that will work.

Another thing, my tablet is rooted...could that be a problem with installing the firmware?
[Android General] makbro:
Rooting doesn't affect the firmware installation...Bad signature warnings are mostly related to incomplete/ corrupted downloads...If the system and boot.img in the archive are complete, you can use Android Kitchen to cook an update.zip yourself OR I can do it for you if and when you upload the archive !!!

[Android General] slayer402:
Just out of curiosity did you change the default write disk in storage? I have the same tablet & was able to install the update through android recovery without issue by changing default write disk back to usb device & putting the update.zip in the internal storage.
[Android General] D1358531:
Well, it was origianlly downloaded to the external sdcard, but then I moved the file to mnt/sdcard2 (which I believe is the internal sdcard). I then tried to install the update, but got the same results. I'll try to change back to usb device and try again. Thanks!

EDIT: I changed it to usb device, then tried to install via CWM recovery, but got the same results.
[Android General] slayer402:
I'm not sure about installing the update via CWM, I'm sure someone will correct me if I'm wrong but I believe it's not possible. I'm pretty sure you can only install that update via stock recovery, which is what I did. You may have to use something like android kitchen to modify the update so you can install with CWM. But don't take my word for it wait for the experts to weigh in.
[Android General] makbro:
Actually /mnt/sdcard2 is the external SD card...the internal memory is shown as USB Storage and /mnt/sdcard ...

---------- Post added at 04:17 PM ---------- Previous post was at 04:15 PM ----------

slayer402 is 100% correct, you cannot install official update thru normal CWM recovery, try to use the "install zip from sdcard" option of CWM recovery and place your file to the root of sdcard2, that is your external SD card...Or, you can use stock recovery or cook a CWM flashable ROM from the update.zip...Since you have uploaded the zip, I'll try to find some time to cook a CWM flashable ROM for you using Android Kitchen...

By posting a reply I, by no means imply that I am an expert...I'm in the learning phase too :)

EDIT : I have seen you "update.zip" file, it cannot be flashed via CWM recovery, you have to use Stock recovery, place the "update.zip" to the root of sdcard (not the external one bu the one shown as USB storage when plugged in to PC or shown as /mnt/sdcard within file manager or root explorer)...When you'll reboot in recovery, it will automatically start to apply "update.zip"
[Android General] D1358531:
Thanks so much for your response! So, I cannot install the update through CWM...how do I get to the stock recovery?
[Android General] makbro:
You can select the "recovery_ICS_Stock_403.img" file while using "Update 3" procedure of csns in this thread to get stock recovery:-

A2107A-F compatible rom's?

Ok, it's been asked many times in this forum, but I still do not see a definitive answer. Are there any A2107A-F specific custom roms available to try out? I note that most of the roms referenced here are for the A-H model and am wary about trying any of them as the h/w specs are different.

The A-F model is WiFi only and no calling functionality. Anybody?
[Android General] makbro:
No custom ROMs as yet (Based on my search)...Only a few stock Images and updates posted (By garringm and D1358531 on this thread)
[Android General] D1358531:
I tried that, but I was stuck on the lenovo boot screen. So I had to install CWM again. :( Will it be a problem cooking the CWM flashable?
[Android General] makbro:
I would need the scatter file of your device as it is now...You can find that in the back-up created using Gscript Lite...Just upload the "firmware.info" from that back-up, I will generate the scatter file, or you can do it yourself as well using "MTK_ROM_Studio"

---------- Post added at 12:51 AM ---------- Previous post was at 12:41 AM ----------

I want to post this as a general info for all those who are getting their devices stuck on boot (after preloader) following an update or custom ROM and / or any transition between these...

If you compare the scatter files of the stock ROM, the update.zip and the custom ROMs, you would notice that the mounting of "/system" changes from "mmcblk0p6" to "mmcblk0p7" once upgrading via "update.zip" and "/fac" takes it's place...On the other hand, the stock ROM as well as the custom ROMs use the mount point "mmcblk0p6" for "/system"...

This is why you run into boot problems and other operational issues, mainly if update or flashing is incomplete/improper, "boot.img" looks for "/system" at the wrong mount point !!!

One way to get around this problem is restoring the stock ROM thru SP Flash Tool with the correct scatter file and all original images from the Gscript Lite back-up...The other is to cook the ROM using Android Kitchen by updating the device definition and updater script to the correct mount point for "/system"
