Weird,since the essential seems identical to a7-20f I thought that its gonna work.I will still give it a shot,I dont have anything important in the tablet to worry about,if it doesnt work I will try extracting its system folder to make it twrp flashable.

Well,my desire 310's camera works fine on cm12.1 and cm13 with kitkat camera libs :D
[Android Q&A, Help & Troubleshooting] raju sesharaj:
Thanks for the reply

Ok i will wait then. The stock ROM lacks lot of customisation and i hate that. Wish CM was developed for this tablet, but i understand considering how much of the devices were sold
[Android Q&A, Help & Troubleshooting] MaRtYy01:
I managed to flash the tab 3 7 essential firmware (took 25mins and 7gb firmware) and it did boot,but screen didnt work(backlight works tho)

What works:

-power button

-vibration

-backlight

-volume down and up buttons

-probably more things

What doesnt work:

-sound(no startup sound,nothing at spamming volume up

-screen(as I said)

-touchscreen(tested with screen timeout,doesnr react)

-OTG(connected a mouse,didnt work)

Also holding power just vibrates(probably opens the power menu) but doesnt seem to restart the tablet,weird.

Update:Managed to restart it but I cant turn it off to reflash stock rom XDDD also pc and adb doesnt recognise it at all(no beep thing and backlight seems totally bugged so its even harder to recognise when its turned off,f0ck unremovable batteries).

Update 2: Opened it and unplugged battery,flashing stock rom worked fine like that.

Guess it can be fixed with the kernel source but idk it it worth the effort.I saw in a screenshot that its actually 5.0.1 with 3.10.54(non +) kernel.

BTW russians from 4pda reported that new small(~30mb) update to S057 is out- T2-A7-10F_S100_150810_ROW,seems like a kernel patch.
[Android Q&A, Help & Troubleshooting] pix106:
Great, how did you manage to flash it ?

If nothing appeared on the screen, no bootanimation etc... system has not booted. Kernel may be running, but what's really working... adb shell and adb logcat are needed, if adb works.

AFAIK, the kernel source lenovo provides is not enough, as we have MTK components and the MTK sources are not public.

I agree with you, if it's android 5.0 and 3.0.54, there is no need to go on with this firmware, that's what we already have :)

I'm not prompted with this update... yet ?

The version number is weird : T2-A7-10F_S000057_160701_ROW_TO_T2-A7-10F_S000100_

15

0810_ROW-> first date is good, but we're not in 2015 :)

I can't download the file that has been uploaded on 4DA, as i'm not logged in (I had an account there, but cannot read russian, so i can't log in nor register again, and i think i had used a temporary email, so i can't receive the link for people who can't read russian ; may manage it later with some russian people at work :)).

Could someone download this file on 4DA and upload it elsewhere public ?

Maybe some 4PDA guys will read this, as they download the roms and recovery i post on XDA to upload them on 4PDA... :)
[Android Q&A, Help & Troubleshooting] MaRtYy01:
Im pretty sure it had booted.It seems like a driver issue.SP flash tools downloaded 7.2gb and took 25 mins to flash it,but it worked after all

And thats S100:

http://www.4shared.com/zip/gGL4vKdzba/T2-A7-10F_S000057_160701_ROW_T.html

Good thing I understand enough russian to log in :D

Checked it out,still 5.0,still 3.10.54+ and security patch magically dissapeared from settings so yeah...
[Android Q&A, Help & Troubleshooting] pix106:
try and use adb, it's the only way to know what's really working :)

Thanks for the file, i'm trying to download it (link does not open, 502 Bad Gateway, i must be damned :))

I don't understand, "so yeah..." => do you think it's an outdated update ?

---------- Post added at 10:38 ---------- Previous post was at 10:15 ----------

Edit : link opens now, i get a ton of ads but no file download...
[Android Q&A, Help & Troubleshooting] pix106:
you have to activate adb, maybe modifying the build.prop.

i "think", "suppose", "probably"... are not reproductible facts, but thoughts :)

It works because you have a 4shared account, i'm using it anonymously, ton of ads, "wait for 60 sec" that does not decrement... and then nothing.

I already tried using a private browser, with no adblocking, and some other browser...

I just hate ads and ad-filled hosting services ! :)
[Android Q&A, Help & Troubleshooting] MaRtYy01:
Naah,screw it,I have a lot of experience in flashing other device's stock roms and if it does that,well,its simply not compatible.I might just extract the system folder and try to port it,but Im kinda out if time now.I have to port and try some roms for my lenovo phone and idk how to crossport cm12.0's boot.img for our tablet,I got it barely working once but I deleted it and now cant even get through the bootlogo.Ugh,I wish it had mali-400.

Allright,reuploaded it in gdrive for you ;)

[Android Q&A, Help & Troubleshooting] pix106:
Thanks :good:

I'll give it a try later.

Talking about boot problems, I have done some cm12.1 build from source lately, after having set a new build environment from scratch. I think the problems i have with it are related to the init scripts at boot that do not do what they should. I get bootanimation though :p We'll continue talking about building in the build thread :)

Thanks again !
[Android Q&A, Help & Troubleshooting] pix106:
So... I finaly flashed this S100 version.

Obviously it couldn't install on a modified rom... I tried a few things, modifying my TWRP build and the OTA S100 file, i couldn't get stock recovery fingerprint in it, but i did not insist as it's a block based update and it would eventualy fail IMHO.

Then I flashed my unofficial v57 stock rom, which only included v54 stock recovery... it failed to flash OTA S100.

Then I found this "official v57 stock rom" on the same forum we found the first ported TWRP version for our tablet : http://lenovo-forums.ru/files/file/1270-lenovo-tab-2-a7-10-прошивка-t2-a7-10f_s57_160701_row

This forum also provided the OTA S100 : http://lenovo-forums.ru/topic/20142...7_160701_row_to_t-2-a7-10f_s000100_150810_row (with no ads ;))

I don't know how really "official" it is, anyone has info about the official way Lenovo releases official firmwares ? :confused: ... if they do...

It's the same for previous official stock roms actualy.

I compared my unofficial stock rom with this official one (using md5) : it's close and consistent (boot, EBR1, MBR, logo and userdata are the exact same files).

Due to the dump method i use for system image, or my limited knowledge (i use SPFT ReadBack + MTK DroidTools, and only get full size images, not smaller content size images), i can't compare system images.

Anyway, I only flashed its recovery.img (v57) and it successfully flashed the OTA S100.

So v57_unofficial + v57 stock recovery can flash OTA S100

S100 OTA: i can't see a real difference for now, android security level is not shown anymore, as you noticed too.

I will make a backup of it (unofficial v100 Stock Rom :)), and then start playing with it (twrp backup to dump it, root, debloat, updates...) and see if i can get kernel info (for exemple...).

I would need some other tablet to compare versions :D

[Android Q&A, Help & Troubleshooting] Dinaiz:
What's the difference between the A10 and the A20 ?
[Android Q&A, Help & Troubleshooting] pix106:
I checked S100 closer :

- many files were created on 2015-08-10

- i checked a few libraries that were updated from S54 to S57 : for example /system/lib/hw/sensors.mt8127.so, the file in S100 is the same than S54 ! I checked a few other files... S54 version too.

So... it looks more like a downgrade actually.

I don't know why this version pops out on 4pda and lenovo-forum... Maybe there's a reason.

I have restored my version 57 backup now :)

Lenovo Tab 2 A7-10 Not Responding after Flash Pls Read Details.. Please help me!!

I have update my Lenovo tab to lollipop but since it was not working then I thought to downgrade it. I have no experience of any programming or technical Knowledge. What I did is following thing:

1. I read a blog on XDA which said process of downgradding of tab. I did as was mentioned there. But that was for Lenovo tab 2 A7-10 F with mediatek 6522 while mine is Mediatek 8127. During Flashing it asked something like different MT number but I click okay casaully. Since then my tab is not getting switch on.

2. Then I gave it to service center but they told nothing & told it will take 5000 rupees to repair while original cost is only 4500/-.

3. Yesterday I tried to flash tab one more time and I removed battery & done the process. SP tool detected my tab & flashed successfully but I was unable to switch it on. I have flashed Lenovo Tab 2 A7- 20 stock ROM downloaded from Russian website. After this my Laptop Detect my Tab as Lenovo Tab 2. A7-10.

4. Then yesterday only Once again I flashed Lenovo Tab 2-A7 ROM with mediatek 8127 & SP tool flash successfully but Still I am not able to Switch on Tab. Nothing happened when I press different Keh Combinations. This ROM is available OK n XDA with something TWSS recover. I have used only M8127 Scattered file.

5. Still my laptop can detect my tab as Lenovo Tab A7-10. What should I do to make it alive? I can not even go to recovery mode as it is not getting switched on. Or It may be possible that it is in bootloop. But as a newbie I can't detect that. Please Help.
[Android Q&A, Help & Troubleshooting] pix106:
Don't post the same message on multiple thread : i reported your post on TWRP thread, as it has strictly nothing to do with TWRP.

I don't realy know what you should do but flashing a stock rom again and see what happens. Latest KitKat firmware if S041, i suppose you already have it.

Some more technical info, not related to this model, could be useful : look for threads, here and elsewhere, about general MTK device revival, not specific to this model, you may find a way.

Good luck :)

If it works, i guess it should be booting fine then.

Flashing wrong firmwares on a tablet can brick it.

IF, only IF, your device is realy bricked, you can try something like this : http://www.engineerthink.com/blog/2016/07/how-to-unbrick-hard-bricked-mediatekmtk-android-phone/

I never had to use such methods, i can't help you further, but you can google "unbrick mtk device" for example and see what it is about before trying :)

1. No screen at all not even Boot Logo.

2. Can not go to Recovery mode. Functional key combination not working.

3. Even while I am charging my TAB I dont have any sign of Charging as well. Dont know weather battery is charged or dead.

[Android Q&A, Help & Troubleshooting] pix106:
You wrote here, and on twrp thread (reported and deleted yesterday) that you flashed a wrong firmware for some other tablet on your tablet, and then you start spamming on many threads, even the ones that are not related to your problem but to your revival attempts.

You were already told yesterday your problem is not related to TWRP or anything else, seemed to have understood and apologized for posting in wrong threads.

Ok.

And today, you only write on my stock rom thread that your tablet is not booting anymore after flashing my rom... (edit : your post has been reported and deleted, thanks to the moderators)

Are you stupid ? By doing this you're insulting the person that is trying to help you !

You know it was not my rom on any rom's fault but only your fault, you flashed some other tablet model rom on your tablet and try to revive it with any rom you find.

So stop spamming on different thread, as your problem is not related to one particular rom/recovery/whatever you tried AFTER you messed with your tablet.

You should read and learn more before trying to flash things on your tablet, and be careful on what you do.

Anyway... one last chance to understand i'm trying to help (and i really shouldn't) :

the word you are looking for is "bricked", you bricked your tablet, it does not boot because you have flashed some other model firmware on it and it can't work. Simple as that.

Yesterday i already gave you the way to search google for info, and a link to a howto for bricked devices, read again.

Last post from me as i don't know much about unbricking devices, and you're being disrespectful.

Hi

I downloaded the camera Mod by amk19 and in the instructions it said if flashing successful then deleted the arms folder in system.

I did that and now the UHD and Quad HD sections are missing in cameras settings.

I didn't do a backup because I'm an idiot.

I flashed stock ROM successfully and rerooted but the 2 selections in camera app are still missing.

Anyone know what I do about that? Also the mod didn't work anyway as nothing had changed apart from that.

[Motorola Droid 3] sd_shadow:
you mean unlocked?

That should be fine, did you verify md5 checksum?

The carrier must use bands that are compatible with the Droid 3

see TECHNOLOGY section http://www.phonearena.com/phones/Motorola-DROID-3_id5305

and see if bands match the carrier you want to use.

Which RSD Lite version?
[Motorola Droid 3] Shakbazian:
The phone had become locked by the time I knew what to ask for.

Codes match. I am using Rsd lite v.6.1.5. I remember seeing somewhere that it will work with that carrier. I can't post pictures, but Rsd shows "N/A" for all the device properties, though in the bottom box under model it shows "fastboot CDMA_solana s"

Could this be a driver's issue. Too many extra non Motorola drivers? I installed the remaining network adaptor and modem drivers.
[Motorola Droid 3] sd_shadow:
That should be correct. You only need to use RSD Lite, if you have a custom rom installed, or the phone will not boot correctly.

If stock rom is work goodm you can skip to next step

Root
[Motorola Droid 3] Shakbazian:
I have rooted. Verizon is not giving out any pin numbers that will work. Is there a software work around for this Sim Network Unlock Pin? There is no contract for the droid 3. I picked it up on Amazon. I can still access the menus.
[Motorola Droid 3] sd_shadow:
Stock rooted should be fine

some Droid 3s just do not accept the unlock code

there is a limited number of times unlock code can be tried

what is current system version?
[Motorola Droid 3] Shakbazian:
5.6.890 Switching from global to gsm network shows the Pin screen again.
[Motorola Droid 3] sd_shadow:
you could try flashing stock rom with the droid 3 utility aka

ovelayer’s .906 1_click sbf .exe
[Motorola Droid 3] Shakbazian:
Should I bring this to Verizon and pay for a month, just to unlock it?
[Motorola Droid 3] sd_shadow:
no I would not

i may have misunderstood,

you have tried unlock codes?
[Motorola Droid 3] sd_shadow:
if you are seeing "The phone is subsidy locked. Please contact...",

an incorrect code was entered too many times, and the phone has locked you out.

even if to get the enter code screen again, and have the correct unlock code, I don't think it will work.
[Motorola Droid 3] sd_shadow:
Because of the way the phone was locked, every droid 3 has 3 or more possible unlock codes, only one of them will actually work.

there is no point entering the same code more than twice.
[Motorola Droid 3] Shakbazian:
Have tried the codes. How many numbers are they usually?

I cant rename or switch out the build.prop file either.
[Motorola Droid 3] sd_shadow:
look like this

27234487

78863555

You need root, verify root access, with a root checker

you need a file manager with root options
[Motorola Droid 3] Shakbazian:
Is the sim network unlock pin necessary for verifying root access?

Verizon did give me an 8 digit pin. As of now I do not have root access with the droid 3.
[Motorola Droid 3] sd_shadow:
No, but if you want to edit build.prop, you need root access

only 1?

did you tell them it didn't work?
[Motorola Droid 3] Shakbazian:
Just rooted it with the 1 click root by http.......//www.psouza4.com/droid3/unbrick.htm

Unless that isnt a real root process.

I am thinking that it is likely that once it is subsidy locked no other codes will work.
[Motorola Droid 3] sd_shadow:
depends on what version you used, what was filename?

I would just use this version

Pete’s Root Tools

or use

Motofail

That is Likely the case
[Motorola Droid 3] Shakbazian:
Flashed with version 5.3.890 found on his website. Errors in the root and also the .Temp Adb root procedure and I can't change the build.prop
[Motorola Droid 3] sd_shadow:
just use my link
[Motorola Droid 3] Shakbazian:
Yes, I used the links from the google docs page.

Moto fail was just viruses attached to a Vlc download.

There was a problem with the phone not being recognized in night saver mode that it had defaulted to, but using performance mode it worked to the last steps.
[Motorola Droid 3] sd_shadow:
Motofail is not a virus, Devhost is a little tricky, try one of the other download mirrors, i just updated list
[Motorola Droid 3] sd_shadow:
You can't edit build.prop without root.

Editing build.prop does you no good, if device is still sim locked.
[Motorola Droid 3] Shakbazian:
trying again with a sim unlocked 0A.64 "5.7.906 .xml" droid. Is there a different process to root and flash? I guess i made a mistake flashing the 890's radio.

The signal showed 4 bars after being sim unlocked, now it is showing no signal after the radio flash.
[Motorola Droid 3] sd_shadow:
unlock code was accepted?
[Motorola Droid 3] Shakbazian:
Yep but with a droid 3 I had had from a while back and stopped using. It is 0A.64 "5.7.906 , so I'm guessing it's an older droid.
[Motorola Droid 3] sd_shadow:
Blur_Version.5.7.906.XT862.Verizon.en.US is the newest version avalible

only way I know how to root that version, is motofail
[Motorola Droid 3] sd_shadow:
906 cannot be downgraded
