I've flashed the TWRP v1.0.2 via Rashr, I think it was a success. When I boot to recovery, it shows a permission to modify system partition, so I swipe to confirm. Is that ok? Is that means that TWRP is permanently replaced stock recovery? I'm not really sure what I'm doing :silly:

Everything seems fine though, TWRP looks good, I can operate them just like on my lovely Moto E :good:

By the way, before the TWRP splash screen, the screen flicker for a fraction of seconds. It gave me heart attack :eek: hope that was a normal thing

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

Oh, one more thing. Actually this is happen since the first day I bought the tablet. If I transfer files through USB cables, they're always either corrupted or has 0b in size, is this happens to other A7-10f too? But this problem never occured if I'm transferring files via wifi.
[General Questions and Answers] pix106:
TWRP has indeed replaced stock recovery, that's why you flashed it :) But this message is not related to that at all.

It means that default is to mount /system partition read only, but it can be mounted read/write if needed, and this options should be in settings menu.. No big deal, just forget it...

Nope, check your cable.
[General Questions and Answers] rly:
Okay this is kinda weird, if I transfer file from tablet to PC, everything is fine. But if I transfer from PC to tablet, the files are always get corrupted no matter if I transfer it to internal or external :(

This is only happenning for USB cable transfer

When I'm copying file from PC to tablet (video or music), on PC I always get popup windows, asking if the file probably cannot be played on tablet.

I'm guessing about maybe the cause is decoding process on the tablet, but still I'm not sure.. :confused:

What probably cause this issue? Is this software or hardware related issue? If hardware is the culprit, then maybe I'll unroot and revert all the system back to stock and asking for a replacement unit :(

FYI:

- Lenovo Tab2 A7-10f MTK8127

- I've tried all other usb cable in my house

- I'm on stock S000044 firmware

Today I tried porting exception os from a7-30hc,no success-doesnt boot.Can anyone find a porting tutorial for mt8xxx?

And that 3.10.54+ kernel seems suspicious to me.Idk,might be an issue for rom porting.Cant find other device with it.

BTW,somebody can give a shot to try to flash the a7-30HC stock rom,I flashed the desire 320 stock rom to my desire 310 to get the 3.4.67 and it worked well,a7-30hc has the 3.10.54(not +) kernel and since there are a few roms for it in 4pda,I guess there could be ported more.

EDIT:I forgot it has a different chipset so dont even think about flashing it.

Lenovo Tab2 A7-10F (Indian Model) running Lollipop 5.0 lost Wifi and Blueetooth

I am a Lenovo Tab2 A7-10F user from India. Bought this three weeks back. It came with Kitkat, updated to Lollipop without any issues. Rooted and removed some bloatware. Later removed Launcher 3 and pushed Apex Launcher to system. After making all the changes that I required, I cleaned dalvik cache and restarted the system. My goal was to remove root access as I have already made changes that I required. However I forgot to open Kinguser and revoke root access. Instead I went and cleaned dalvik cache and reset the tablet. Tablet booted fine, launched with Apex Launcher fine, but it has lost two functionalities namely; Wifi and Bluetooth. When I try to switch on these two, it fails to switch on. The toggle goes back to off position by itself immediately. I have tried resetting the tablet using default recovery (It is in chinese for some strange reason) but it produces the same result, as in the Wifi and bluetooth still don't switch on.

Anyone faced similar issues? Anyone has any ideas how to mend this? If no, I guess the option is to reinstall Lollipop or Kitkat again. If so, can anyone send me links where I can download a proper untweaked default indian version ROM (Kitkat or Lollipop). Also let me know how to install it. It would be better if there is an option to update Lollipop using default recovery itself so that I can drop the ROM in SD card and update. Also since my recovery is in chinese, it would be greatly helpful if someone helps me to identify which lines to click to update through SD placed ROM.
[General Questions and Answers] pix106:
Tablet has 2 recoveries, Chinese recovery, and stock recovery you can access by booting with both volume buttons presed.

The stock recovery can be replaced, not the chinese one.

Also you shouldn't use kingroot, simply flash twrp (you'll find it here) and flash latest stable SuperSU.zip (or let twrp root with Its embedded SuperSU)
[General Questions and Answers] prmbasheer:
Thanks a lot, for the useful input. I have managed to install Kitkat using SPFlash Tool. I am yet to root again. Will try your instructions to access english recovery and also use twrp to root. Thanks again :)

It was a big relief to get back my tablet to original state and was happy to see Wifi and Bluetooth working. So, I haven't fiddled it further. Will root may be after a week or so. Now, I don't have the time and energy to spend on recovering if something goes wrong again.

I wasn't aware of that. Thanks.

I rooted the tablet using iroot. It is rooted now. Removed some bloatware. Now I want to unroot. The SuperUser app installed by iRoot has an option called "Unroot". However when I click that, It takes me to another app that was installed by iroot called OneCleaner. After that I don't know what I should do in OneCleaner to remove root access. Everytime I click unroot in SuperUser, it takes me to OneCleaner. Any help with this is appreciated.
[General Questions and Answers] cracktech:
This is the tricky part.! Unrooting iRoot/Kinguser/ Kingoroot ( all Chinese root app different names but actually same source) is best left alone. Please find in XDA thread topic ( Supersume topic) the problems faced by trying to replace the Chinese app with SuperSU, then you will understand what you will be facing. FYI unrooting process by Chinese root will leave behind a lot of orphan files and rerooting it using SuperSU is difficult/ risky at best. I am just an observer here and do not have your model on hand but the firmware structure is the same for most Lenovo with MTK SoC. I know you just want to unroot but read the recommended threads for you to understand the challenge you are going to face.

Hey guys!One guy ported Resurrection Remix MM 6.0.1 to A7-30.Dont get too excited,he hasnt uploaded it and the a7-30 has mali-400,not mali-450 as the A7-10/A7-20.Its running on kernel 3.4.67 and the baseband is 2014/11/25 so I guess he came from the stock 4.4.2.Thats a link to the post:

Bro , if your ported ROM from amazon fire or any source will work than please tell me , I'll also start porting all the ROMs. On A7-10
[General Questions and Answers] pix106:
with a friend (Doume) we started to build omnirom 5 on A7-10 a few months ago.

Our github is there : https://github.com/PixNDom.

Twrp recovery, boot, using prebuilt kernel and a few blobs, and a lot of time trying, made the tablet boot with graphics ("buggy", red borders quite often), partial audio and bluetooth.

It was my first attempt building a rom from sources, it was not Doume's first try (he had achieved building a rom for another device), but we didn't know how to go on... and project stalled as time has passed.

I think we used too many blobs and mixed repos (mediatek drivers, lenovo sources...).

Lately i was thinking about trying again, maybe we coul try and join our efforts ?
[General Questions and Answers] MaRtYy01:
I dont know how to build roms from source bro XD

But anyway,thied porting a rom called Nexus LP from the amazon fire and it didnt boot at all.It was stuck on the lenovo powered by android logo forever,which means that I f*cked up something while replacing files.

and this: http://www.mtkroms.com/2015/08/install-real-lollipop-on-all-mtk.html

porting guides.The fact it didnt start glitching after it booted means that the kernel is compatible.So somebody else can try to port it or offer me another guide.BTW,I also downloaded slimlp and the system folder was in a .dat file ;( that means not all roms for the fire could be ported without linux...

I just posted this about roms/recoveries

for android 6.0, it's on 64bits tablets -> not possible IMHO

for android 5.1 of Tab3 7 essential, maybe it's possible.

I never ported roms, and may not try, as i'd prefer building a rom from sources.

As stated before here, we started building Omnirom 5.1 with a friend (Doume) a few months ago, we tried hard and finaly stopped after a while.

I recently started again from scratch, current state is building a working TWRP recovery.

Next would be building a kernel using lenovo sources (it builds fine, but does not work, i think sources are incomplete)

Any help from experienced MTK rom builder would be appreciated
[General Questions and Answers] MaRtYy01:
I think the essential is mt8127 too,flashing its stock rom might work.The only issue is that it has back camera,that might be a problem.I would like to try it but I cant find its stock rom anywhere :/

We will need it because it has newer andoid sdk level,currently I think I can crossport only same sdk roms.There is cm12.1 for 3.10.54+ (if it uses that kernel).Who knows,lenovo might update it to 6.0 just like they updated the a7-10f to 5.0 .

Did the omni 5.1 boot after all?I tried porting from the fire 2015 but I think it has some patches in the boot.img that are a problem.
[General Questions and Answers] pix106:
Omni 5.1 booted with prebuilt stock kernel, with no wifi, medium performance graphics and a huge ammount of blobs.

Hi Everyone!

I've recently got an A7-10F, and we planned to use it as a family device (with Android 5 and multi-user support)... but I think most of you guys know, Lenovo has removed the support from it's latest version.

I've read around and every tutorial / description I've found was for older versions and don't work, is there a way to re-enable this? I've got it rooted, so that's not a problem, but I would like to avoid flashing cfw if possible, and I'm comfortable in editing system files :)

I've seen your stuff over at github, can I help in any way to speed things along? I'm not really familiar with this level of the Android environment, but I've been a web developer for a few years.

I think I found the problem.. Xposed to old :D

The Custom ROM was made December 2015 and therefore the xposed version is too old for the xposed multuser-module! I will update xposed (i saw, you use version 81) and try it again!

YES!! Upgrading xposed version to at least 81 made the trick. Then the "multi users" module also works. Is there any way, to add the icon/menu in the settings-dialog or do we have to use it from the status bar?

Did you only use xposed module ? Or did you have to enable multiuser in build.prop too ?
