Need Help With Root! (Lenovo Tab 4 8) - Android General

Posting this to see if I might be able to get some help. I have intermediate knowledge of Android OS, so I'm looking for step by step help. I currently have no PC access which makes all of this much harder. Device I'm currently on is ZTE Zmax Pro, (no root on marshmallow 6.0.1)which probably won't be any help in this situation. I've looked through several threads but haven't found something I can really use. I even looked into a couple 1 click root apps, but they didn't work. Not only that but I'd rather do it manually anyways.
Here's all my device information for the Lenovo Tablet
Model: TB-8504F

Try with #King_root
https://kingroot.net
Sent from my [device_name] using XDA-Developers Legacy app

I've tried that a few times already. First time was after I unboxed the device(stock firmware I believe?). Went through 3 software updates while trying in between each one as well. I'll go ahead and try again though. I'll post update.

Kingroot Update: Ran root process, hangs at 01% for about a minute until jumping to 15%. Got to 16% and process stopped. Was prompted to either Reboot or release memory. After reboot, the root process went up to 23%. Third time around it goes to 19% and keeps doing it. Do I keep this process going or am I wasting my time? Does the software try a different method each time? There's only 18 root requests too. Not sure how popular this tablet is but that means it's being rooted easily or nobody has one lol

Is it the lenovo tb 8504f you want to root because we have the same device and i know how to root it very easy please answer me i also need your help

[Q] Backuping a chinese brand phone

I recently bought a chinese brand phone but the stock ROM is ****ty and is full of lies.
It supposed to have android 4 on it, but I'm pretty sure it isn't. It not only looks and reacts totally different but many aps give parse errors when installing. It's pre rooted and has Antutu pre-installed. but I'm unable to update Antutu because it always keeps using the version that was preinstalled. Antutu claims this:
model: X315e
CPU: Qualcomm snapdragon MSM8660
CPU model: ARMv7 Processor rev 2 (v7l)
CPU freq: 1024.00 MHz MHz (yes... 2x MHz)
Android version: 4.0.6
Build nr: X315e DuakCore 1.5GHz 1GB RAM+1GB ROM
Kernel : Linux version 2.6.35.7 ([email protected]) (gcc version 4.4.3 (GCC) ) #5 PREEMPT Tue May 19:07:25 CST 2012
I'm not sure how much of this that can be trusted, since I know the phone has less Ram that stated.
What I want to do is find out how to backup the stock ROM, and maybe find a custom ROM that works on it.
The seller clams it runs on a MTK6575, I found out that powering it up while holding down the volume up key gets it in recovery mode. But it only shows a picture to state that it can't find a recovery rom. I have to take out the battery to get back to a normal phone.
Any help here would be appriciated.
Summing up:
- How to install a recovery rom
- How can I make a decent backup of the rom
I managed to make a decent backup with a Russian program called mtkdroidtools.
That program also tells me that the processor isn't a MT6575 as claimed by the shop, but a MT6573 instead.
I kinda expecting this already, but it really bursts my bubble in hoping to get ICS on it.
Next thing I need is a recovery.img. After making a search for MT6573 I stumbled on this thread:
[AIO][TUT] ClockworkMod recovery for any MT6573/ 75/ 77
It explains how to make a clockworkMod img for MT65xx. I have been at it all day yesterday. It uses Cygwin and then either perl script or "Android Kitchen".
I've tried the perl scripts first. Unpacking was no problem, but when repacking it uses "Switch". The "switch.pm" module was removed from perl recently so it doesn't work. I tried changing the script to use other switch like functions but it keeps throwing me errors. (maybe someone with an older version of perl can get me a "Switch.pm")
Then I tried the "Android Kitchen" plugin. This one seems to run fine, and finishes without an error... but I can't find an output recovery.img anywhere.
I would contact the writer of that thread, but since I'm a noob to this forum I'm not allowed to.
So if anyone can help me with any of these issues then please do.
I'll be very grateful
I just had an epifanie, I was thinking I could just make a script without the switch in it, for now I only needed it to repack the recovery anyway.
So I hardcoded the script to only repack recovery images and that was it. everything works fine!
I would like to thank all those who were interested in helping me.
If anyone can still get me the switch.pm then please do. I can still use it.
And if anyone has a good place to start looking for roms that might work on my phone then that would be helpfull too.
Thank you XDA and thank you yuweng, I already thanked you in your thread but you deserve a second one

Mtk6577 Root, build-120920.ics v13 -problems

Hello all,
I have been a reader of work on here for sometime when needing help with a problem, mainly with mine and my wifes Galaxy mini due to it's low built in memory..
Anyway on to this little problem, I have been toying with the idea of rooting my china import hero h2000+ So over the weekend I started collecting information/bits towards it.
Tried the easier route with unlockroot.com free version that couldn't unlock the shells.
Then tried one from Youtube but there's was a new version (phone wise) using MTKdroidtools v237 That one went though okay and had the super user there then when you reboot it, it was gone.
Then tried, sorry can't remember the person/user but was Root_with_Restore_by_Bin4ry_v17. Press one for normal all goes though fine just nother there at the end again.
Then tried Root_with_Restore_by_Bin4ry_v18 all the same as the v17 but once rebooted and back on there's a little problem..
It seems that all the apk files have been wiped, but on closer inspection they seem like they are there after managing to install the apk for ES File Explorer so I've managed to in still other apk files to keep me going for the moment But it will not reinstall google play. as I can't get it back to 'as before'. I also noticed that the recovery mode no longer works the screen will come up as if it loading it but just turns off.
In an ideal world I would like to either get back to fully working or rooted & working, but read there a bit difficult to.
Other detail are:
Android Version 4.0.4
Baseband Version: MAUI.11AMD.W12.22.SP.V7,2012/08/20 16:49
Kernal Version: 3.0.13 [email protected] #1 SMP PREEMPT Zed Sept 19 05:06:34 EDT 2012
Build number: 120920.ICS.V13.FWVGA.CN.COM.4P4.MT6628
Also just found that it does not Reboot Recovery from about phone.
Any help or guidance would be very much appreciated :fingers-crossed:
Thanks
Anyone? please.

[Q] Rooting S5770 with Jelly Bean

Hey all
Problem: I installed clockworkmod, gapps and 4.2 on my s5770 without rooting the device. I was messing around with play store trying to download apps but it turns out my internal memory is pretty much full so cant download. I've tried changing the download location to the SD card but didn't work. I found a few websites that say its possible to expand internal memory but the device needs to be rooted and here lies the problem. Im not sure how rooting works but I have tried using a 4.2 method but didn't work and I've also tried a 2.3 method but still didn't work.
Ill list the specs for you guys based on the about device section in phone settings. I want to know how to root the device because so far, everything ive tried hasn't worked or if their is a method to expand the internal memory without rooting that might help too.
regards.

Nobis 9" Internet Tablet (Model NB09) - Custom ROMs?

Hello,
I've had this Chinese knock-off tablet running Android 4.1.1 for a few years now. I haven't really used it, since it doesn't have enough installation space, even though it says there is over 5 GB of space. However, I was able to root it the other day using the KingoRoot tool, and change the install location to my SD card using a terminal emulator. I would like to also add a custom ROM to my tablet, to allow for added customization, but I have found very few resources online covering this tablet. Are there any compatible ROMs from other devices that could work on this device? I apologize if this a bit of a newbie question, as I am relatively new to Android modding/rooting.
Additional Info:
Kernel Version: 3.0.8
Build Number: NB09.20130929.v005

MediaTek T906 Tablet(Made in China!!)

Good Evening All(or whatever time it may be there),
I'm new to XDA and Rooting, etc. etc. I purchased a MediaTek T906 Tablet(Made in China!!). After I received it and charged it, the first thing noticed it wasn't allowing some apps to download and install. Keep in mind this is suppose to be Android 9 and 512Gig 8Gig ram device.
Below is what MTK Droid Tool v2.5.3 says about it(and yes I Root it, am fully aware that it voids warranty):
Hardware : MT6582 (MT6797 is Fake!)
Model : T906
Build number : T906_vEN52S2_TB_20191205
Build date UTC : 20191205-085910
Android v : 9.0
Baseband v: MOLY.WR8.W1315.MD.WG.MP.V54, 2018/01/02 15:01
Kernel v : 3.4.67 ([email protected]) (gcc version 4.7 (GCC) ) #1 SMP Thu Dec 5 16:56:01 CST 2019
Too root(successfully)it I used KingoRoot and Got SuperUser Status/Privileges. I did a lot of reading on root and other root apps(to be used in conjunction with). Long story short, I'm trying to get a specific app to download to this tablet and am not sure how to go about it. I did the dump data/cache thing in Play Store and Google Play Services and reboot. Didn't work. Did all the steps before I root the device. I even used Root Essentials Editor to mod the device name and manufacturer, that didn't work. And the time zone is set to right time zone. So, I'm making this post asking for some guidance and/or help on what I can do? Any and all help is greatly appreciated!!
I am in the same situation as the previous poster with the same Version, Kernel, Baseband, Build and my experience with this should be considered at a beginner's level. In researching this and came across a post that indicated that the tablet is not actually Android 9.0 but suspected to be KitKat. Please, if anyone knows how I could get this setup with Android Oreo, I would be grateful.
Hi guys,
just got the tablet too, it also seems to me it has this config:
- MT6582
- 1GB RAM
- 16GB Storage
- 1280 * 800, 7.19" display
- Android 4.4
Not sure what options there are, but I hope there are some newer Android builds that would work on this?
I'm following
So far....
I have been successful in rooting my device and hope to find a ROM that will move it up to a level that will allow KODI -Leia to be installed. I will let you know what my findings are. I'm just afraid as I don't want to brick the device.
Hi guys . Same problem. But. Works to me. Go in accounts remove account. then try loggin again.
uncheck all boxes. Unynchronize the two options in the account. Agenda and contacts. Deselect the check options. If it doesn't work restart and turn off the wifi. then rewire. Do it again. good luck
A brother in distress
I've got the exact same issue with my T906 Mediatek. I downloaded the Root app (Thanks!) and kept trying to get the things to load and run. I'm specifically having the issue with Alexa app. I can find it but I get that the app isn't compatible. It runs on my Samsung phone that's running A9.0. It keeps saying the app is already installed, yet it isn't . I went into the Play Store and Play Services apps and deleted the updates and caches as suggested on YouTube. No difference. I'm sort of at a "What Now!?" POINT.
Any help would be appreciated.
Be safe out there and for goodness sake, wear your masks until this crap is beat.
The REAL OldGeezer
you can't upgrade generic android devices until version 9. Android 9 seperates the drivers with the treble abstraction layer allowing you keep the drivers and upgrade the rest. The T906 has android 5.11. If you run CM lite scan you will see a huge Opera beta file that is always 3 times your storage. This is how they fake the RAM and ROM sizes. If you take off the back and look at the board you will ussually see printed on the board 1GB ram 16GB rom. They have also faked the CPU by using the ROM for the upspec version with better camera, screen resolution and CPU which uses the same drivers. Thus these are also falsely reported. Sadly Google no longer supports android 5 for things like Google sheets so your apps will soon stop upgrading. I love this machine because the screen size makes it cheap for 50 USD
Help to get ROM image to restore same model
I have the same model but when trying to get root access managed to brick it. I have got SP Flash working and managed to get some T906 firmware on it so I get the Mediatek logo and battery charging symbol on screen however the boot options i.e. Fastboot etc just gives an error message when selecting any of them.
I've got a development background but new to Android and scatter files but is it possible for anyone on this thread with the exact same model to help get back to a working system? I assume there is a way to back it all up using SP Flash ?
hi everyone are in the same problem boot error !!!
how to solve it I have tried in all ways but I find myself as soon as I turn it on boot error !!!! you can not even go into recovery?
Help!!!
These manufacturers need to be found and dealt with cause they are robbing customers. They are giving fake specifications. They need to be sued asap.
I got a Mediatek tablet and try put it in recovery mode and now I got black screen with blue bar with SIM and Chinese Characters. Any way to fix it

Hello guys.
I have a different problem with my T906. It works fine and it is fast and reliable but I had problems downloading apps from the Google Play Store. When I checked it said that the Device is not certified under the Play Protect Certification. I remembered that it came without the Google Play app and I installed from another APK store (apkmirror.com) and it installed without issues. I've tried to download another Google Play app but can't find the correct match for my version and OS (64-bit - Android 8.1).
Any help will be truly appreciated.
I've just created a dump of this tablet with flash tool, maybe you can try to revive yours

MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Btw I'd welcome any kind of rom that would make this device more usable
