job done.

I had win10 x64, installed win7 x64 driver. had S000018 4.4.2 kitkat. updated to S000019 kitkat. and after this versiyon tablets own updating worked and got 3 updates! first kitkat, then lolipop and again updated version of lolipop.

important things are driver, running sp flash tool as admin, scatter file, connecting the device while holding sound button and after clicking download in the flash tool.

thanks for the help.
[Android General] Nickco43:
Apparently this recovery tool works with Lollipop MTK devices. I am not brave enough to test it since I just got my tablet back from RMA.

Your msg is not directed at any person. It could be me or to somebody else? I am shutting down permanently my BLOG and FB support pages 31-Dec-2015( it has been 5 years). So you better be quick IF you want the A7-30HC Lollipop version S000126 (second version) you have to be a member on my FB Page before I will give you the link address.

Background preparation before and after using SPFlashTool (all are given). Please beg , steal or borrow Win7 PC. Other Win OS will result in failure to complete flashing process .

Does anyone have the SP Flash Tool or OTA images for the A7-30GC variant? I'd like to have both for Kitkat and Lollipop for emergency's sake in case I decide to tinker with my tab somehow.
[Android General] cracktech:
I have both HC/GC Lollipop SPFlashTool version. The HC is S000126 the GC is S000120 both Lolli. I can give provided that it is not shared on any Websites. I had it for about 1.5 month already and trying to preroot/ debloat WIP.
[Android General] blakegriplingph:
Is it the international version? The ones I see appear to be the Eastern European variants afaik.

EDIT: Just sent you a friend request if you don't mind, well since you don't intend to share the files and would like to pass it privately.
[Android General] cracktech:
Dont understand your question Eastern European variants? Only GC versions are targeting the Ukrainian/Russian/ Slovakian markets. I had mine sold in Malaysia but on the box is said to be originated from Sllovakian Lenovo but it is specially build to be "A7-30HC-MY" but after the upgrade to Lollipop from Russian sources (I mod it so it doesnt install bloatwares of 270Mb to be 25Mb (but dummy files) so that no after market apps are installed at all) It is now HC pure Lenovo ROW version (Rest Of the World).

[Android General] blakegriplingph:
So I noticed. But let's say I go for the OTA route, that is if Lenovo does roll out any updates of that sort at all. Assuming I'd still be able to get my tab to boot (yeah, you told me about those bootloop issues before), will I be getting that SD card issue as well?
[Android General] cracktech:
It is a standard AOSP feature for all Android Lollipop and some KitKat not to be able to write to sdcard.
[Android General] blakegriplingph:
Not unless if you either root it as you outlined earlier and on the Lenovo boards, or if the applications are aware of it and have write access permissions from what I read.
[Android General] cracktech:
Tough luck for finding a stock ROM that allow to write the first time out of the box.Good luck tell me when when you find one.That is why I root all my Androids and put in my mods to the point that I didnt realise that most KitKat and Lollipop doesnt allow write to sdcard.

Guys i need some help. I rooted the device with kingoroot and then i tried to pass the philz recovery but something is wrong and when i reboot in recovery the device stuck in a black semi lighted full screen. After that is not responsive to anything till the battery runs out and then after i charge it it starts normal but again if i reboot to recovery same huppens.

I think i destroyed the recovery partition but i don't seem to find anywhere the original recovery img to pass it on or a correct twrp or cwm for my device.

I have the a7 30 dc with 3g... can someone help?

Thx in advance
[Android General] markosjal:
Just a quick note . I upgraded lenovo tab 2 a7 30gc using the method and files here youtube video >>>> watch?v=B9xxjzMELJQ

I tried the windows lenovo tool and the ota updates and both said i was running current version.

After lollipop upgrade no more annoying touch screen problems and everything works.

There was one issue i ran into at installation and when i clicked download and connected tablet nothing happend but after disconnecting and reconnecting tablet it worked as expected. Also only one of my many USB cables actually worked for this update.

What i really need however is the ability to mount an nfs share so tjat it is available to apps . accessing nfs is one thing but i need a permanente mount at boot.
[Android General] cracktech:
Under normal cicumstances you should use MobileUncleTools to install Customs Recovery and if it goes to a black screen just bypass the Recovery reboot and go back and re "update" (using MobUncTool naming) the Recovery back to the the 3E (factory recovery) I got mine in similar situation while modding the A7-30HC ..taa daa! "black screen with flicker" I reboot and waited for the phab to get to the home screen (also by pressing once in a while the power buttons to wake up the screen)and reupdate it back to 3E Recovery. Honestly this A7-30/10/20 models has got no reliable customs recovery since no gurus are using this low end device. Philz Recovery/TWRP/CWM/CTR are all non existence for these models and anybody claims to have put in customs recovery , had to be taken with a bit of salt. Probably one or two for KitKat version but nada for Lollipop.

I sympathise with you but to get the A7-30DC (I actually first heard it here) firmware in SPFlashTool version is no where to be found since we only have HC/GC/H/F I dont even know the specs. If an SFlashTool format ROM can be found for "DC" at least you can extract the "recovery.img" and reflash it back. Sorry mate!

greatly thank full

if someone helps me . thank you:o
[Android General] cracktech:
You are lucky Rj5676 at least the it didnt complete the flash process. It would have hardbricked your A7-30 if it went through. Do your research first before you do something st%#&!d like this. The A7-30 HC/H/GC are all MT8382 and the A7-30F is MT8127 (that is a different processor alltogether).

Just closed down my FB/BLOG/Google+ pages that includes the support for ALL Lenovo phones and tablets (at least the popular one)

If you want the Lollipop A7-30GC S000120 in SPFlashTool format please PM me for the download links. (But let me remind ALL A7-30 users there are no working Philz/CWM/TWRPrecovery so far) dont install any Philz Recovery/TWRP/CWM unless it is posted in a reputable Forum or else you are gonna end end with Recovery that shows a black screen.
[Android General] ralax:
Unfortunately i found your forum in the last moment...i have A7-30F with MT8127. I wanted to root if with sp flash tools and scatter from MT6582_Android_scatter and it said something like "it is not your version". So now I have not working device, i can't turn it on, just a black screen. I thought maybe i need to disassemble it and reconnect the battery, after than just re-upgrade it? Could you help me please guys.
[Android General] ralax:
So...anyone has this model A7-30F (MT8127) with 5.0.1 android version and want to root it:

1. Install KingRoot and Root it.

2. After install SuperSU-Me and run it.

3. Update SuperSU.

4. Reboot it and delete SuperSU-ME.

My device was bricked and couldn't turn on. But finally i could repair it. Special thanks to - cracktech :good::)
[Android General] blakegriplingph:
Care to elaborate on how you unbricked it? I am comfortable with flashing Allwinner tabs as they have a hardcoded bootloader and is thus resilient to bricks, but MTK's a bit touchy on that subject.

Also, has there been any progress with cobbling up a CyanogenMod port for both the MT8127 and MT8382 variants of the A7-30?

Flash stuff using stock recovery?

Hi@all,

has anyone ever tried to flash something using the stock recovery? Maybe Xposed or SuperSU update?

I never used a stock recovery since a custom recovery was available for all my devices til now.

The Lenovo Tab 2 A7-30H is my first Mediatek device and the first one there is no custom recovery for.
[Android General] cracktech:
For a low end device like this the developers are more excited to work on other projects, so far there are 3 customs ported ROM ( 1. EXCEPTION OS , 2. AOSP5.02v3 3. Galaxy6 LP) but not heard of anybody working on CM ROM . Just be careful ported ROM do have their problems. but a 100% working TWRP 2.8.7.0 was just released the past few days for HC/GC/H/DC only but nothing on the F. My advise is not to touch the customs ROM (but your choice) bcoz as it is the A7-30 is already a very touchy phablet if you installed certains apps that we normally use on other Android

might

cause random reboots on A7-30 like Cheetah Mobile apps, 360Security, Lenovo Cleanit (might cause random reboots if on Kingroot/iRoot - dunno about SuperSU but there are reports from users about it)

---------- Post added at 10:02 PM ---------- Previous post was at 09:53 PM ----------

Lenovo stock recovery is referred to as 3E recovery, NO you cant install SuperSU zip using 3E recov! It has to have the script rewritten extensively and the apk need to compressed to Lenovos standard to produce the "xxyzz.apk.

p

". What the hell for only a few days ago TWRP 2.8.7.0 was released for A7-30 HC/GC/H/DC and I can confirm its 100% working becoz I just install it today on my A7 in under 3 minutes flat. Most MTK devices for the more popular models have got a variety of customs recovery for them lining up but it is just for this A7-30 that the Recovery took so long I waited 6 months for it. MTK is fun to play around the firmware bcoz it has no bootlock and it takes 5 minutes out of the box to root it.
[Android General] Cypher_01:
Nice! Do you have a link for us? :)

I made a decition. I've returned my Lenovo Tab 2 A7-30. I'm afraid I'll never get a Mediatec device again, even though the price point is great.

Anyway, thx for all the information in this thread! I wish you a good time with your tablet! (No sarcasm, really)
[Android General] cracktech:
None taken, on my BLOG in June 2015 I wrote that the A7-30 is a not recommended buy although the price is cheap for nearly anybody. First because on KitKat there was so much problem with screen lag, OTA updates were sofbricking/bootloop the device, the camera specs is just plain rubbish. But I had other MTK devices I own such as the A8-A5500 tab (excellent but no Lollipop upgrade), my S939 6inch phone,an A880 6inch,a A369i as a toy. But MTK SoC are the reason of Lenovo price:performance features and with the introduction of the 10-core SoC is sure to heat up the competition.. I am thinking of venturing out to Lenovo Qualcomm device the PhabPlus 7 inch phablet.
[Android General] Cypher_01:
That's comprehensible. Usually I use high end devices for huge amounts of money, but everytime they were worth it.

I only went for the Lenovo Tab 2 because of an Amazon sale. And I have to confess, it was a mistake.

I am so satisfied with my Sony Xperia Z3 Compact Smartphone. Next time when looking for a tablet, I'll go for a Sony or Nexus, even though they cost 3 to 10 times the money of a Lenovo tablet.
[Android General] AfterShöck_1:
So hey, i managed to get the .img from 4PDA but now I just can't get to install it, Flashify just doesnt want to work and the drivers are giving me headaches (I'm on Windows 10, maybe is that?)

Can you give me any pointers on how to install it?
[Android General] cracktech:
First you need to be rooted. Are you root? Then for any MTK powered Device please use MobileUncleTool(it needs root) to "upgrade recovery". It only takes 30 seconds to do it. I tried using SpFlashTool method but it doesnt work although flashing works flawlessly but it didnt flash the TWRP ( the flashing process got through 100% but when going into recovery it only shows the 3E recovery(factory recovery). I tried it 2 twice. Backup and restore works flawlessly but before doing anything else do a "backup" first, as I found out when trying to install "SuperSU update.zip" it wipes my "system partition" and was unable to bootup after showing "installation of SuperSU is succcessful" . It is only the "SuperSUupdate.zip" that causes this problem as when I install my own mod zip it got through OK. The SuperSU has this script that mount and dismount system partition and that causes it to either wipes out my system partition or fail to mount the system partition (only when installing original SuperSU.zip.) Lucky thing I did a backup so I was able to recover. (I nearly wanted to reflash)

I have told the admin at 4PDA (which I am an active member) about this error, and I put up a warning post.
[Android General] plane17:
hi all, please i need help. i have lenovo a7-30DC tablet and i upgraded on 5.0.1 via ota, but i have some problems on 5.0.1 and i want to downgrade back to 4.4 kitkat, i was searching for stock kitkat rom but i did not find DC version. please help me and i have one question: does downgraing will void my warranty? thanks
[Android General] cracktech:
Told you guys about the risk of doing OTA, didnt I? The Lollipop is stable like we did on HC/GC version with SPFlashTool format ROM. But your DC is an unknown device to main stream Forums , so there is no ROM in SPFlashTool format for DC, that I am sure of. Sorry cant help
[Android General] plane17:
Thank you

Thank you but i found DC version of stock kitkat but when i flashed it, my tablet did not boot on, when i was pressing power button there was no light on screen and nl vibrate too, it froze, nothing happaned whem plug in charger or plug in computer with usb cable, so i flashed again lollipop and it works fine, please tell me if you know what happend and why it did not boot, i really want kitkat, thank you again ans sorry for my english it is not my language
[Android General] cracktech:
Your call! I would prefer Lollipop rather than KitKat. Because of screen lag issues of KitKat. Your case "didnt boot up" , I would suspect that the ROM was not the original one. It might be a cut and paste work by somebody. Theres is a possibility that he copied a GC or HC kernel into his so called DC version. That is my guess only.
[Android General] AfterShöck_1:
I am, its just weird that flashify didnt work, i have flashed some 4 or 5 devices with that app before.

But yeah, mobileuncle got it done, although i had to get the apk since playstore lists the tablet as incompatible for some reason.

Thinking of trying the AOSP rom now, you've got any recomendations for it? besides backing up, of course.
[Android General] cracktech:
Dont belief one bit that one app can work on ALL devices. I used RASHR Recovery flasher (but never Flashify) and found out that it doesnt always work on ALL the devices I own , but it worked on my PiPo M9Pro RK3188/ but RASHR didnt work on my AML M802, I tried "Recovery Flasher","1-click Recovery Flasher" and anything in between to get it to flash the recovery. But MobileUncleTool is only for MTK SoC and dont go and use it on any other SoC! No although I am aware of AOSP developments ROMs in Russian Forums but , if they are not popular and receive accolades that only means one thing it is full of bugs! I wont recommend them since this stock firmware is already AOSP compliant with minor additional Lenovo apps.

Yes for both KitKat n Lolli. I am puzzled when you say unable to root using kingroot.apk? All A7-10/30/20 over here in Asia we 100% rooted successfully using Kingroot. If not you can try Google " iRoot.apk" but download from official websites. 99% of MTK device can root using Kingroot version 4.65. Please turn on your WiFi during rooting process.I am currently on Kingroot 4.65. In order for you to install TWRP pls use MobileUncleTool( must be rooted) copy TWRPrecovery.img on your sdcard then select " update recovery" on MobUncTool.Dont use Flashify/ ect only MobUncTool

What recovery? Factory recovery? TWRP Recovery? Yes I have the full GC ROM in SpFlashTool format , if you want the factory recovery you can download the ROM and extract the factory recovery from it. If you want TWRP recovery you will need to provide me with an e-mail from the link on my BLOG : http://malaysianandroidsupport.blogspot.com/ because I dont want the TWRP link to be floating around the web, therefore I will not provide the link here.

Hello

Please help. I have a Lenovo Table 2 a7-30 HC, I did a downgrade over the SP Tool to 4.4.2. ROOT done and over Flashify uploaded TWRP. Unfortunately, after boot into TWRP the screen width and twrp does not respond to touch, until battery power is exhausted, I can not use tablets. After the acquisition system moves, but when it enters TWRP again, I can not choose, does not touch.

Can I flash original recovery? I searched but found nothing.

A7-30HC Lollipop root

Hi everybody,

I am no expert for rooting phones/tablets, just IT who knows only what need to get my devices worked.

I just want to share info about my rooting process, which can be potencially usefull for another user.

I have Lenovo Tab2 S7-30HC tablet, running Lollipop 5.0.1 (v125) and tried to root.

Based on discuss here, I tried Kingroot to make root and it worked for me.

The problems comes, when I tried to replace Kingroot and install SuperSU.

I have previously done this (with S3 mini) by W0lfdroid script (su, sh /sdcard/mrw/root.sh) and that was my first try with my tablet.

W0lfdroid script did not work for me, as for script version 2.0, 2.1, 2.3 finally I found 2.4 and still no luck.

After hours of googling, I choose SuperSu-ME, as some bad-english-speaking-youtuber guy mentioned, its 100% safe.

Untill this, all my replace tries was unsucesfull, but made no damage, simply Kingroot removed and SuperSu not working, but still, Kingroot can root it again.

But, with the SuperSu-me, my tablet became bricked.

I resumed Lollipop 5.0.1 back (not sure, what exactly I done, simply download ZIP for SD card recovery and it worked, I am no flashing guru) and tried to figure out, what the hell had happend.

My ideas was:

1. What If, KingRoot and SuperSu-me developers, simply dont like each other for obvious reason and there is some kind of countermeasure inside Kingroot latest version (4.8). What about, to try some older version.

2. I luckily remember some error messages from terminal, when trying W0lfdroid's script v.2.4, which was "already installed" (I guess SuperSu), even when I uninstall supersu. What if, W0lfdroid's script does not presume, supersu can be already installed.

So, after clean recovery to Lollipop 5.0.1 (v 125), I tried this strategy

A. Kingroot, but older version (mine was com.kingroot.kinguser-4.5.0-120-minAPI8.apk, search for it somewhere), made root

B. do not, once again> DO NOT install SuperSU

C. Run W0lfdroid's script v. 2.4, mine was Replace_Kinguser_with_SuperSU-v2.4.zip (terminal, su, allow root permission, sh /sdcard/mrw/root.sh, then some errors appeared, then restart and taaa-daaaa)

Overall> still not sure, if Kingroot lattest 4.8 was the problem, but, whats important: you, yes you, impatient semi-IT-semi-BFU, do not install SuperSu, w0lfdroid's skript do it for you.

Hope, this can help anybody.
