A little video - flashing with SP Flash Tool

(sorry for the repost, but I know people follow this thread independent of the other general A2107A thread)

For a few months I've been answering people's questions about using SP Flash Tool. I know it's frustrating. I understand, no one was there to show me how to use it either. So I made a video:

https://www.youtube.com/watch?v=9V7m9UCM4-c

Hopefully there are just the hard questions and answers left after this. Unfortunately after videoing the whole thing through, I realized it didn't show my thumb on the VolUp in most shots -- oops.

Anyone interested in a collaboration to get 4.2 running on this?
[Android General] syserr:
Of course I am! But... unless you have MediaTek sources, I don't think you can do it. Let's discuss your ideas here!
[Android General] nashy10:
I don't have the mediatek sources which does make this extremely hard, im looking for a device with a similar prcessor and such that runs 4.2 to port from
[Android General] syserr:
I was looking for smooth feature-ful ROM of a device that had a MT6575 processor also. But I wasn't limiting myself to 4.2, *any* would be interesting.

Oddly, it seems the PRELOADER/UBOOT/BOOT are intertwined much more than I thought. A good resource if you want to learn more about MTK builds and the underlying system including booting and drivers...

https://github.com/luckasfb/Development_Documents

Specifically, I like these:
[Android General] anil@aol.com:
I have been using v7 for some time now. However, I had to reflash as for some reason the tablet became very slow and often unresponsive. I am unable to sync to a calendar app (aCalendar) that I use and encounter the same problems that you mention. Would you please let me know which apps you placed in the zip file and from which built did you take them. A link to these files would be appreciated.

Thanks.
[Android General] ShilohDaniel:
I have a start at a 4.2 rom. So far it has boot issues I can't figure out at the moment. I haven't forgotten about this little tab yet. Just slow from health issues.
[Android General] armyofpunk:
Hope your doing OK shiloh
[Android General] syserr:
Great to see you back!

How are you tackling this? Are you using the MTK Framework - ALPS? Or just trying to make the kernel boot?
[Android General] nashy10:
What is the intention of the partitioning? More free space on the partitions that need it? Any performance differences?
[Android General] syserr:
Yeah, basically making max room for apps. DATA can only get up to 2GB because of odd MediaTek limitations, but it seems most of our devices are partitioned with DATA at 1GB or so. My son ran out of app space on his -F, so I decided to adjust it and share.

I doubt their are any differences in performance.

Download Rom

Hello ShilohDaniel

how I download your rom ?

I want to be betaTester

Congratulation
[Android General] girlgeek:
Still interest in this thread and Thanks

Just wanted to let you know that I'm one more person interested in this thread. As I revisit it and other ones I will keep thanking people. Lots of info here.

Am ready to do the Mobile Uncle and CWM piece of this and then install ROMs I am happy to test. I had some shell issues with resolving vars in the backup script and ended up running it outside of gscript I am new to gapps and I think I didn't get a good emulator or complete install of busybox, all that done.

I am interested in more fully functioning USB, the ad I saw in purchasing this tablet said I could stream hdmi video to tv through the usb port, not sure what they meant by that. Cannot use external usb radio/dvb-t tv tuner. I was interested in using this tablet as a media server for my tv. Better bluetooth would be great too!

Thanks for all the good work on this, and I hope Shiloh and her family are doing well. Jellybean would be nice :)

Any news on the BarebonesAlpha 9.1 Rom?

Okay, I installed it and it works perfectly fine, actually a little faster than the Alpha 7. The thing is, it does not come with the Play Store or Google Play Services, which is kind of awkward. I tried installing them and they work for a moment until I try to download something, then it crashes and crashes and crashes and keeps telling me that it crashed... I don't know if you all had meant for it to be like this or there is still something going on with the rom, or maybe just my tablet. I hope ya'll can make this tablet the best it can be! Shiloh and syserr, ya'll are awesome! Keep It Up :good: :victory:
[Android General] dan1239:
Continuation of this thread... please

Hello for all you people still watching or waiting on this thread, I have tried to make some little touches to the BareBones_Alpha_7 and turned into the BareBones_Alpha_7.0.1... :D It might not be changed much but I have tried to do some minor things. I have also changed the boot sound and shutdown sound, I made them both so hope you like... Here's the link to it: https://www.dropbox.com/s/cy9pkulgernuwsq/BareBones_Alpha_v7.0.1.zip Stay cool Lenovo Crew... :cool:
[Android General] syserr:
Hey, good job. My pref is removing boot/shutdown sound/animation, but any fiddling with ROM for this thing is encouraged!
[Android General] dan1239:
Thanks :D I was even trying to get into the Ubuntu Touch and try fiddling around with it, but that didn't work out so well... I hope at least some more people are still working on this rom. I will try to keep making more changes to the rom, I guess speed and fix the panorama in this update. Keep on with the keepin' on!
[Android General] dan1239:
Here is a little update... BareBones_Alpha_v7.0.2:https://www.dropbox.com/s/u8hd2b6g6pyxqa8/BareBones_Alpha_v7.0.2.zip; Fixes: Camera App Panorama wasn't working so I replaced it with the original, PlayStore is the newest version now (no more updating), Added a browser (Maxthon for Tablet), Updated ES File Explorer to latest version, Added the PlayMusic App, Added a MIUI Theme for Smart Launcher. I Hope Everyone Likes It! :victory:
[Android General] dan1239:
Could we try getting the bootloader unlocked? If anybody could, that would be great... I'm trying to put Ubuntu Touch on this tablet but I have no idea on how to get to the bootloader...
[Android General] ssenemosewa:
Hey dan1239, I just replied over in the other thread before realizing that you'd posted here. My bad! From that thread:

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.
[Android General] dan1239:
Well I only did some visual and audio changes, I am not very familiar with the kernal and editing the system. I just mostly customized it. I am however trying to learn how. The changes I made are in some of my past posts, but they are: Smart Launcher instead of Go Launcher(mostly because of the huge lag and memory hog, I also added PlayMusic(since there wasn't a music app in the rom, Added ES File Explorer, Updated the PlayStore app to the latest version so that it won't have to update when you first start it up. I also added different sounds like new startup and shutdown sounds, as well as a nexus keyboard click. Lock and unlock sounds are like the iPhone, since they are better quality then the original. And etc... You will definately notice a change. While I'm typing this I really wish I could figure out why ever word is underlined as spelled wrong. I think its because the dictionary doesn't have all of these words in it... Idk So yeah, that's about it.

And FM radio'

A2107A-F battery over temperature issue

Hi A2107A-F users

I know this thread is related to ROMs for -F models but I would like to ask you if somebody of you have had issues related to "battery over temperature" messages as per is commented in the following lenovo link:

https : / / forums . lenovo . com / t5 / Idea-Android-based-Tablets / A2107A-F-battery-over-temperature-issue / td-p /1309883

The problem is annoying since after few seconds the message appears the tablet shuts down.

In the last post from ssenemosewa (489), he mentioned that Shiloh's ROM managed this issue better than Syserr's ROM in the sense that at least every time the message appears it could be dismiss without the tablet just shutting down.

I would like to make sure if this problem is a software or hardware related issue. In the case of a sw issue, changing the stock ROM for a custom one could solved my problem?. I will appreciate your kind comments.:)
[Android General] syserr:
Not sure, I don't have a tablet with that problem. I bet it's a hardware issue... as you can guess, flaky hw gets hot. Maybe fire up "adb logcat" and watch system messages as it gets warm.
[Android General] ssenemosewa:
Still here, and happy to weigh in on the issue (for what it's worth).

I'm leaning towards it being a hardware issue. On my tablet, the reported temperature seems to be completely unrelated to the actual temperature. As an experiment, I put my tablet in the refrigerator for an hour. You guessed it: It still gives over-temperature warnings!

But here's the rub: It seems to give those over-temperature warnings when I run any app with higher graphics requirements (like mapping programs, games with animation, etc.).

So...cold environment...hot GPU? Also, I tend to get over temperature warnings more when the battery is low.

As to Shiloh's ROM managing the issue better than Syserr's ROM, yes, that is certainly the case. I think it has to do with minor differences in the SystemUI.apk build. I'd love to disable the over temperature function entirely but don't have the programming experience necessary to do so.
[Android General] ssenemosewa:
I'll try it and report back as soon as I can. What is the exact name of the app/author on Google Play? There are a couple that match that name.

It might be a few days, as I'm currently swamped at work.

Try it, you'll like it! Seriously, it definitely improved things for me. I installed Syserr's SE_SRS_A2107A-F_S486_130221-signed.zip ROM, but with Shiloh's A2107A-F_S483_121115.zip ROM's kernel spliced in.

Syserr's ROM supplied all the functionality/stability that I was looking for...except for that blasted instant temperature shut down. The kernel from Shiloh's ROM eliminated that quirk. I still get the over temperature warning but clicking either button just dismisses the dialog box without shutting down the tablet.
[Android General] Doowa:
The application is Smart Battery Monitor made by Andreas Auer, here is the link (with blank spaces)

https : // play . google . com / store /apps /details?id = at.aauer1.battery

Ok, I will try A2107A-F_S483_121115.zip and let you know my comments.

In your first reply you told about SystemUI.apk , what is that file and how it is related to the battery temperature issue?

thanks
[Android General] syserr:
You should make a ROM! ;)

---------- Post added at 10:40 AM ---------- Previous post was at 10:38 AM ----------

From your errors (I'm no expert) it sure does sound like a hot battery... Especially that the temp goes down running off charger.

I'll have my son install it on his -F.
[Android General] ssenemosewa:
I was searching for solutions to the battery temperature pop ups and stumbled upon this XDA thread.

Basically, he modified the SystemUI.apk to eliminate the pop ups and notifications. But the A-F ROM is odexed and the patch only handles deodexed ones. Plus, it doesn't prevent the tablet from shutting down when it hits the thermal limit. That seems to be handled in the kernel (boot.img).

Hey, it's one thing to play Baron von Frankenstein, grab pieces of various ROMS and cobble them together with just guesswork as your guide. I freely admit my novice status and will leave true ROM creation to experts such as you and Shiloh. :o

---------- Post added at 08:28 PM ---------- Previous post was at 07:59 PM ----------

Okay, I tried it. And my temperature readings were all over the place! I'm leaning toward the bad temperature sensor conclusion.

Right now, I'm charging the tablet. The temperature is showing 10 degrees C! I ran a video...the temperature dropped to 5 degrees C. I took it off the charger and the temperature went to 15 degrees C. Stopped the video, and it went back to 10. And, no, I am not conducting my tests from a walk in refrigerator...room temperature is currently 25 degrees C.

Earlier today, the tablet was reading 60 degrees at times...sometimes it would give me over temperature warnings, other times it would not.

But at no time did the tablet shut down...thanks to Shiloh's magic kernel and the stability from the rest of syserr's ROM.

A2107a-f only foxtrot V100 works

Hi,

I have formatted my A2017A-F . Now it can start only with foxtrot V100 rom.

But that one is meant to be for A2107A-H, so I cannot connect to wifi or do anything.

I have tried all available roms , installation goes fine with CWM 6015.

But startup hangs at lenovo logo.

If I try stock roms with Flash tool. then it times out at country code selection.

Any suggestions / help ??

thanks,

Finally it worked with stock rom for SPFT.

I had to select fac, saw that in readme file.
[Android General] syserr:
Great! Yes, if you format, then the FAC partition needs to be restored also... and the tool will not do it be default. Sorry, I was not around to help.
[Android General] Doowa:
Hi ssenemosewa, thank you for doing the measurements, I think 20-35 degrees C are normal temperature values.

I was very busy during these days and I couldn´t reply this post.

By my side, I followed your suggestion and installed "Shiloh's magic ROM" and you were right, as soon as the overheat warning appears I can snooze or dismiss the notification and the tablet never shuts down.

The bad news was that still the tablet was detecting high temperatures around 50-60 degrees C and that situation made the "overheat warning" appeared many times until becoming an annoying thing. Also i powered off the tablet for some hours in order to reduce the "heating" but after booting up still the tablet was detecting high temperatures measurements, so I decided to remove the battery from the mainboard and after some minutes i put it back. After that procedure I noticed average temperature values dropped around 30 degrees C. I am monitoing the battery voltage and temperature with BatteryIndicatorPro. The mentioned app has a setting option where every battery event can be logged and export to a csv file.

Question: I have an issue with Shiloh's ROM related to AutoRotate Screen function, it is not working on my tablet, Each time i want to rotate my tablet I should follow the procedure: press the power button for 1 second, then rotate, then press again the power button. Are you having the same issue?
[Android General] ssenemosewa:
No, rotation works fine for me. But I'm using syserr's ROM with Shiloh's kernel, so maybe that accounts for it.
[Android General] Doowa:
sorry I don´t understand, I thought that A2107A-F_S483_121115.zip file was a ROM but not a kernel.

The procedure I followed was:

1. make root

2. backup with Gscript Lite

3. generate scatter file

4. install Mobile uncle

5. generate recovery.img file with michfood scripts and install the new recovery file generated

6. copy A2107A-F_S483_121115.zip file in a microSD card

7. enter into recovery mode (CWM6015) and install the ROM A2107A-F_S483_121115.zip from the microSD card

I see, I need to install the same ROM as you, please tell me where should I download the ROM??

thanks in advance
[Android General] ssenemosewa:
Sorry for the delay. It's been quite a while since I did this, so I had to go back and try to recreate my steps in order to refresh my memory! Here's a basic explaination of what I did and how I did it:

First off, some basic terminology: A ROM is a file that contains the system image of the Android operating system and apps. The Kernel is part of the ROM and translates software input/output to code that the hardware chips (CPU, GPU, etc.) can understand. The ROM is typically a zipped archive of the image components. The Kernel is a file (boot.img) inside the zipped archive.

As I mentioned before, Syserr's ROM was great (stable, functional, etc.) except for it instantly shutting down when the tablet thought it was overheating. Shiloh's ROM didn't have all the features that I liked in Syserr's ROM, but it didn't shut down on temperature warnings either. What to do?

1) I extracted the Kernel file (boot.img) from Shiloh's ROM.

2) I unzipped Syserr's ROM into a temporary directory.

3) I copied Shiloh's boot.img over to Syserr's extracted ROM, overwriting the existing boot.img there.

4) I rezipped the "Frankenstein ROM" and flashed it to my A2107A-F using CWM.

5) Profit!

So, get copies of Shiloh's and Syserr's ROMs and give it a try.
[Android General] Doowa:
Dear ssenemosewa, thank you a lot for clarifying the whole procedure.

I will give it a try !! :good:
[Android General] gtajunkie:
Would it be difficult for someone like me, with no experience, to change your package to use Apex launcher instead of Smart Launcher?

Or would you consider upping one that has Apex, or even the vanilla ICS launcher?

Thanks for any help!

Edit: never mind, just figured something out (I'm new at this): installed Apex launcher after a fresh flash, then titanium backup, then uninstalled smart launcher - so now only Apex. Thanks for upping the ROM!

Sorry that I didn't answer... I haven't even been thinking about this tablet. It's been sitting on my desk for the longest time accumulating dust. I am still having problems with connecting this tablet to a computer. It refuses to connect and allow me to view its sdcard. Thus I am unable to flash the tablet and fix anything. And great job! I am currently using Go Launcher because of the speed and customizability.

Please can anybody help with my usb problem!? THANKS!!!!
[Android General] syserr:
You may or may not like this. I am not a Windows guy, so what I would do in your shoes is this:

1. Grab a Linux live CD... any should do.

2. Get to a prompt, (console shell)

3. run "dmesg" and take note of the last 5 or so lines of text, so next time you run it you will see more on the end of the output.

4. plug in your tablet

5. See if there are additional lines at the end of "dmesg" output talking about USB

6. Boot into SPFT, (read how in my FAQ)

7. Look at the end of the dmesg output again.

If you see nothing, I think your USB connecter is dead. If you see something, I suspect Windows issues. I use Linux for everything except for SPFT, for that I use XP in VMware on Linux.

Possible Development?

So, ive had this tablet kicking around for some while, and ive been coming to grips with ubuntu and kernel editing and MTK's stupid procedures. Managed to create an installable zip of a port ive made from a ZTE V970, stock ics. i figure stock ics would run a lot cleaner on this device, less bloat, etc. currently the installers getting stuck at unmounting the system, i changed all the scripts mount points so everything should be correct. unpacked kernel and did some tinkering, it may possibly boot. anyways, just wanted to post and see if anyones interested in giving this development a shot, will readily post my folders and progress if requested.
[Android General] nashy10:
Sorry for the double post. unmounting isnt too big of a deal, either way seems to be stuck at boot. suspect it has something to do with the kernel, coming from a phone instead of a tablet. if anyone has a better idea of whats wrong with this build, be my guest. http://d-h.st/irKN thats the rom zip file if you want a crack at it. boot.img may not be in that version but youll find it here http://d-h.st/irKN
