Hello, great is your work, but i found some problems, the link TWRP_3.0.2_Lenovo_TB3-730X_Android-6.0_recovery.zip does not work any more and also my tablet does not work with the file SuperSU#.zip, i don't know what happened, can you help me? thanks so much!

please reply to me through email dangvanhan.cfic@gamil.com

thank a lot my friend!
[Upgrading, Modifying and Unlocking] 0xAF:
The link is working, just checked. Take a look at the first post, it has the working link.

The SuperSU should be flashed from the TWRP recovery (from the link, which is working). Then you will have root.
[Upgrading, Modifying and Unlocking] Agustine:
Thank you so much, i will try to work now, i hope i can root my tablet. :)

---------- Post added at 04:17 PM ---------- Previous post was at 04:08 PM ----------

I am sorry to bother you admin, i already download the file, but unluckily it was already corrupted. I could not flash it. Hope that you can help me some how...
[Upgrading, Modifying and Unlocking] 0xAF:
What you mean "corrupted"?

Can you provide more information on what the problem is?

Please read the first post again and follow step-by-step the instructions.
[Upgrading, Modifying and Unlocking] Agustine:
I am happy that you answer my question. Thank you so much!

What i mean is the file TWRP.zip you provide in the post which i can't open it admin. Do you still have the original one. Can i have it please admin. And also the SuperSU#.zip, i can flash it on my tablet, because the result appeared in my screen is INSTALATION ABOERTED! So i think i don't have the good file or may be something wrong i don't know. I hope i can make you understand clearly admin. Thank you so much. My email is dangvanhan.cfic@gmail.com
[Upgrading, Modifying and Unlocking] 0xAF:
The TWRP file, which is linked is good.

Have you unlocked your bootloader?

Have you booted the recovery with the fastboot command?

If so, then it is the SuperSu file that is incorrect probably.
[Upgrading, Modifying and Unlocking] Agustine:
I don't have the TWRP.zip sir, the file which you provided it was corrupted, i could not open it. I am stucking there, i need TWRP.zip and SuperSU#.zip sir. :'(
[Upgrading, Modifying and Unlocking] Kellicros:
First of all, thanks so much for these, 0xAF, and honzazkrumlova.

Just to report that I have successfully rooted the device with the latest official Magisk(11.1), this could make things easier for people who wants Xposed or other Magisk mods.

I personally have Magisk's Xposed(SDK23) module installed, no issue so far but I will do more testing, will report back if I have any issue.

EDIT 25/02/2017: Everything works perfectly without issue, highly recommended if you do not flash the custom recovery, many mods can be flashed directly with Magisk.
[Upgrading, Modifying and Unlocking] 0xAF:
The link on the first post (https://goo.gl/5ZW6uG) is working. It opens a zip file in google drive. You should click on the DOWNLOAD button in the upper-right corner of the page.

It will download the TWRO zip file. Then you should unzip this file to get the TWRP img file.

Then follow the instructions on the first page.

If you download a corrupted file, then you have problems with your browser.

Or if you use proxy (which can be invisible to you), it could be a problem of the proxy server.

Or it could be a problem of your antivirus program.

Try downloading the zip file from another computer and follow the steps in the first post.
[Upgrading, Modifying and Unlocking] 0xAF:
Thank you very much for this information.

EDIT: I've updated the first post to inform other users about Magisk.
[Upgrading, Modifying and Unlocking] Agustine:
May be you are right sir, i will try to find out the problem, if there is any issues, i will report to you sir. Hope that you can help me again. Thank you so much for your hospitality. :)
[Upgrading, Modifying and Unlocking] Agustine:
Hello, my tablet was bricked after i have mistake in rooting it. now i am looking for a firmware of it. my tablet is Lenovo tb3 730x . Do any one have the firmaware? i appreciate any help. Thank you guys in advance!
[Upgrading, Modifying and Unlocking] 0xAF:
How bricked is it? Can you start TWRP if you have flashed it or with the fastboot command?
[Upgrading, Modifying and Unlocking] Agustine:
My tablet is freeze in the logo. I think that is the result of my mistake in installing SuperSu# using TWRP. I will try again using the computer to enter the TWRP MODE. But i think i don't have that lucky chance since my tablet was bricked already. I hope that you can help me find out the firmware of this lenovo tb3 730x. Because if i don't have the firmware, i can not use my tablet again sir. Thank you so much again for your support!
[Upgrading, Modifying and Unlocking] Kellicros:
What exactly did you do? did you "swipe" when you boot up TWRP? If your tablet is only bricked by installing SuperSU you can try a factory reset.

I have downloaded the Russian firmware for safekeeping, if anyone knows of a free cloud drive I can upload it there.
[Upgrading, Modifying and Unlocking] 0xAF:
I presume, you did not follow the instructions correctly and you've allowed TWRP to touch your system partition.

Here is a system backup, I've got from [MENTION=7255241]honzazkrumlova[/MENTION]: https://goo.gl/LnRbNI

You have to use TWRP and restore this backup.

I'm using this system backup, thanks to [MENTION=7255241]honzazkrumlova[/MENTION]
[Upgrading, Modifying and Unlocking] Agustine:
Yes, i swipe it, and after that i regreted. I already reset but it still stuck in the logo, i think i need to flash it with its firmware. I am so happy if you give me the link to download and show me how to work also, i am using windown 10. I hope i will not find any difficulty. Thank you so much.

---------- Post added at 09:52 AM ---------- Previous post was at 09:49 AM ----------

Please help me, because i don't know how to use TWRP to back up the system. I am stuck in the logo now, thank u so much sir.
[Upgrading, Modifying and Unlocking] 0xAF:
If you have flashed TWRP, you need to enter the recovery mode with the buttons. Hold the volume button and the power button and start the recovery mode.

If you haven't flashed TWRP, then you need to start the tablet in fastboot-mode (again with the buttons) and then use the fastboot command on windows to start the TWRP.

After TWRP is started, use the adb command to transfer the backup to the SDCard of the device, then use the RESTORE menu from TWRP to restore the system partition from the backup.

You lack knowledge on most of these operations, so I suggest you to read more guides before doing any dangerous operations in future.
[Upgrading, Modifying and Unlocking] Agustine:
Hello, thank you so much for your advice sir, i have a good new, my tablet is rooted. :)
[Upgrading, Modifying and Unlocking] donkeyman1234:
Can I apply this method to tab3 730x (mt8375p 2g/16g)?
[Upgrading, Modifying and Unlocking] 0xAF:
I had no idea that there are non-lte TAB3-730X models?

But anyway, it should be working... follow the steps and try to boot the recovery from fastboot.

If it works, you can proceed with flashing.

Read the instructions carefully before starting.
[Upgrading, Modifying and Unlocking] donkeyman1234:
thank you, I will try this method when I get my order. (ram 2g/ internal storage 16g) it's lte model.
[Upgrading, Modifying and Unlocking] 0xAF:
Ahh, sorry, I misunderstood your previous comment. 2G is the RAM. And now when I'm actually thinking, the chipset is LTE anyway, so there cannot be a model with that chipset that is not LTE.

Just a fast look at the previous comment while I'm at work is sometimes confusing... ;)
[Upgrading, Modifying and Unlocking] Kellicros:
I'm not sure if I should post this here but there is no dedicated forum for this tablet, any help would be greatly appreciated.

I am trying to unroot the tablet for OTA updates but I can't seem to boot my tablet without root, it would always stuck at the first Lenovo boot logo,

The tab would boot fine with magisk/supersu flashed, but it won't boot after magisk uninstalled/full unroot.

I have tried everything I could think of, stock recovery, formatting the internal storage, factory reset, or even restore a TWRP backup of my fresh clean rom without root or any mods/userapps. But unless I flash root into it it would always stuck at the boot screen, I have tried letting it stay for 2 hours but there is no progress at all.

Any idea what could be the culprit?
[Upgrading, Modifying and Unlocking] 0xAF:
Have you tried to flash your original (unrooted) boot partition?

From the backups, I've got from another user, I've flashed his system (up-to-date) partition and now I'm on the latest OTA FW. But when I flashed his boot partition the tabled was not booting, stuck on the boot logo, so I flashed back my rooted boot partition from my backups and it worked.

I don't know why that happened and I had no time to investigate...

For what I expect, flashing clean (unrooted) system and boot partitions should do the trick, but in my case it did not worked.

Anyway, even if you unroot, I'm almost sure you wont be able to OTA upgrade.

When I got one of the OTA updates and unziped it, I saw that the update checks if the boot and system partitions are modified (with hash or checksum). If it was modified, the update will not go.

And since the updates are incremental, they only touches the data in partitions in RAW. The update do not understand filesystems and do not mount the FS. It's like a hexediting the raw data in partition. So if the checksum is not correct, you should never touch the data.

IMO even if you successfully unroot, the checksum will not pass, since you already made modifications on partitions and patching the RAW data will damage the filesystem probably.

The only way to do OTA update is to have a backup of the original partitions. And not just archive with the files of the partitions, but you would need a full dump of the partition.

NOTE: May be if I have some free time in future, I can try to port some ROM from another tablet with the same chipset. Should be relatively easy.
[Upgrading, Modifying and Unlocking] Kellicros:
That seem to be my case exactly, I made the clean backup right after I successfully booted into TWRP for the first time, is that good enough? Because even with that restored it would stuck at boot screen.

Thanks so much for the insights, I did successfully installed the first 2 ota's, until 151031 if I remember correctly, then it started to fail, so I thought a fresh restore would help, but nope. Wonder if the OTA's broke something.

EDIT: Some custom rom for this tab would be awesome!
[Upgrading, Modifying and Unlocking] 0xAF:
Yes, should be good enough. But I don't know why it's not working. As I said, I have the same problem.

Here is 161228 system backup, if you want to flash it.

https://goo.gl/LnRbNI
[Upgrading, Modifying and Unlocking] Kellicros:
Thanks again, I just need to restore it over my current setup, right?
[Upgrading, Modifying and Unlocking] 0xAF:
Yes. No need to factory reset or any other actions, just restore it over your system partition.
[Upgrading, Modifying and Unlocking] Kellicros:
Is there a reason to not flash TWRP though? I am only keeping the stock recovery for OTA updates, but I guess that isn't the case anymore.
[Upgrading, Modifying and Unlocking] donkeyman1234:
Thank you so much, I've rooted my tab3-730x.
[Upgrading, Modifying and Unlocking] 0xAF:
Dunno, I have flashed it, since I cannot OTA anyway.

Brick

Hi

At first thanks for twrp

but I think I brick my tablet and I need your help

I already flash twrp and root

I wanna make my tablet faster so I started to remove some system apps wich include Google keyboard

but when I reboot I always have to enter my password to start android but because I removed Google keyboard , there isn't anything to enter password with it

(I installed another keyboard in my tablet but for entering password we have to use Google keyboard)

So I googled about flashing Google keyboard app with flashable zip. I make flashable zip and flashed it with fastboot in my PC to the system folder

because I didn't mont system in twrp I use fastboot in pc (because monting system brick our tablet)

but after reboot my tablet stop at Lenovo logo and don't do anything else

Now I have to unbrick tablet

I already backup my system partition with twrp

but I can't restore with twrp , because I didn't mont system

I really need help guys

_______________________________________

I have another question too

does anyone use xposed on this tablet?

because when I flash xposed , my tablet stop at Lenovo logo

I solve it by flashing xposed uninstaller
[Upgrading, Modifying and Unlocking] 0xAF:
If you have backup of your system partition, you can restore it. There is no need to mount it. Just restore the backup.

As for the xposed, I'm using it without problems.

You can try installing Magisk first and then install xposed from magisk, there were reports that it works. (see the OP)
[Upgrading, Modifying and Unlocking] Unique_Ali:
But bro when I restore backup , twrp shows eror which you can see at this photo :

(I can't send link of photo in reply because I'm a new member , I will send a photo in massage for you now)

_________________________

And about xposed

I didn't use Magisk

I just flash super user
[Upgrading, Modifying and Unlocking] 0xAF:
Try to unmount the system first and see if you can restore the backup.

About xposed, if you cannot install it, or having problems, you can try installing magisk and install xposed from there.
[Upgrading, Modifying and Unlocking] Unique_Ali:
But bro I didn't mont system at all

It's unmont from first
[Upgrading, Modifying and Unlocking] 0xAF:
From the screenshot, you've sent me, it seems that the system partition is mounted in read only.

Try mounting and unmounting it, so the backup can start...

I dont know why you see this problem, but it should be something easy to solve, i guess...

(btw, you can try this system backup from 161228 - https://goo.gl/LnRbNI)
[Upgrading, Modifying and Unlocking] Unique_Ali:
Sorry bro

I was forget system read only option

I untick it and now everything goes ok

Thanks a lot

Hi folks, i'm having a issue which prevent me from booting into twrp and also flashing it which is "fastboot failed (remote unknown command) i heard that on my tablet(tb3-710l) android 5.1, the flashing commands is disabled by lenevo, and after unlocking bootloader with fastboot oem unlock command it seems that it runs perfectly and tablet does powered on with all my data removed but when i verify my bootloader whether its unlocked or not by "fastboot oem device-info". Please help me cause i really need root

---------- Post added at 11:17 AM ---------- Previous post was at 11:12 AM ----------

Edit: and i'm using fastboot to flash twrp not sp flash tools.
[Upgrading, Modifying and Unlocking] Tzul:
[MENTION=5500243]AndroidLover666[/MENTION] This topic is for the TB3-730X. If you have a TB3-710I, then go here.

Also, I don't think the command "fastboot oem device-info" is supported, hence the "fastboot failed (remote unknown command)" output. To see whether or not the tablet is unlocked, use "fastboot getvar all".
[Upgrading, Modifying and Unlocking] 0xAF:
1. The recovery from this thread is for Android 6.0. I don't know if it works on Android 5.1.

2. Your device is probably with another chipset, so it's not a good idea to try this recovery.

3. Given the above 2 points, it's really bad idea to flash the recovery. You can try to boot it, but do not flash it, unless you're sure it works for you.

4. IIRC, Android 5.1 can be rooted with many installable apps (APKs), no need to flash recovery for that. (I could be wrong, though)

As [MENTION=5919159]Tzul[/MENTION] mentioned, it will be better to go to the correct thread and see what recoveries are available for your device.
[Upgrading, Modifying and Unlocking] AndroidLover666:
Hi there, thanks for prompt reply, i see but i've tried many apk's of roots like kingroot, kingoroot, oneclickroot no progress all fails, and i first try to boot into this (https://nl1.androidfilehost.com/dl/...24965684/recovery_twrp302_Lenovo_TB3-710I.zip) but fastboot give me unknown command error it seems it's blocking boot and flash command and i know that after flashing recovery tablet should be force in to recovery mode rather than normal boot as it will restore android 3e stock recovery.

I have finally booted recovery_twrp302_Lenovo_TB3-710I.zip which is for android 5 i have checked its readme instructions but now it wont boot properly and gets restart itself after the openrecoveryscript like that where its replacing twrp with stock recovery, how to solve this please someone guide.

Looking for a twrp recovery file for the Lenovo/LenovoTB3-X70L/TB3-X70L

current factory file installed is 6.0/MRA58K/TB3-X70L_S000020_170209_ROW

This is a Lenovo TAB3 10 Busineness LTE
[Upgrading, Modifying and Unlocking] 0xAF:
Looks like the chipset is the same. You can try to boot this recovery with fastboot and see if it works. Do not flash the recovery, just boot it. If it boots, check if you're able to mount/unmount the partitions. If it works, you should be able to flash SuperSU and if you want you can flash the recovery permanently.
[Upgrading, Modifying and Unlocking] lostmysandal:
Hey I was wondering, on the box mine says MT8735P LTE Call but WWAN:WCDMA.

What does this mean? Mine seems can only connect to 3G Networks. What was the part about LTE call?

One more thing, I have succesfully rooted the device, what is lenovo scraps that is safe to remove?
[Upgrading, Modifying and Unlocking] 0xAF:
LTE, WCDMA are technologies for data carrier, I don't know what you mean by LTE Call?

If your mobile operator have 4G or LTE your device will use it.

The icons in the notification bar will show "H" or "3G".

Even when it shows 3G it seems it's using the 4G/LTE technologies. At least that's what I saw...

As for the apps, I can't remember what I removed, but almost all of the lenovo apks were removed on my device.

Like "User Experience", "Lenovo ID" or something similar...

Make a TWRP backup of your system partition, before removing anything.

So you can restore it if something goes wrong...
[Upgrading, Modifying and Unlocking] baraja29:
in my suggestion, i think it's better when you show us in video mode,cause with word can make missunderstanding especially newbie just like me lol..

i have bought lenovo tab3 730x too and i wanna try to install TWRP to but, i don't really understand hahahaha
[Upgrading, Modifying and Unlocking] 0xAF:
I think that if you do not understand the instructions, then it's probably dangerous to try them. Even if I record a video of the process, something might go wrong in your case, and if you do not know what to do, then it's better to start reading about all these stuff.

Besides, I do not have the time, neither the will to record a video.

If someone here is willing to do so, please, be my guest, I will put the link in the OP.

I see..ok, I will..

And i was thinking of trying to port from meizu m2.
[Upgrading, Modifying and Unlocking] 0xAF:
That would be nice.

I was thinking to port CM (LineageOS), but no time to even start reading...

and so far, with stripped version of the original rom i see no point of spending time...

If you believe you can make/port more Android Vanilla ROM, that would be very nice.
[Upgrading, Modifying and Unlocking] dmilz:
Yeah. One custom ROM for this animal should be enough..

If actually could port lineage , that could make sense..

Can't start working on it though because am stuck in boot loop..hope to raise it from the dead by tomorrow and try the port
[Upgrading, Modifying and Unlocking] 0xAF:
Just a hint, when I rooted mine, which actually modify the boot partition, I had boot loops when I flashed the original system partition after that...

So try flashing a rooted boot partition and if that helps.

I can give you links to original firmware images, which was sent to me by users.
[Upgrading, Modifying and Unlocking] dmilz:
i Think those will come in handy.. You can give me

boot image (i think this one was original and unrooted) - https://goo.gl/FJo9Fi

Ok..I will appreciate..

Yes I can

If you get back online..

If you have root access on your TAB.. Please make .IMG backups of the TABS partitions using PARTITIONS BACKUP AND RESTORE.. you can find it in PLAY STORE....

Then share with us..I have noticed am not the only one in LOOP?

---------- Post added at 11:45 AM ---------- Previous post was at 11:06 AM ----------

Found a solution guys...managed to FLASH STOCK using SP FLASH TOOL successfully...

Will compile a FULL ZIP with the necessary files and then upload to MEGA.. Link will be shared here by TOMORROW.. whoo finally the pain is over
[Upgrading, Modifying and Unlocking] 0xAF:
Here is the rooted boot.img - https://goo.gl/6r3TrD

I guess we have the bootloop problem, because the system partition has something from the rooting too... and depends on the rooted boot.img. I had no time to check it, but this boot.img should solve the problem.

This is TWRP backup and can be restored with TWRP. If you want to use it with other tools, it's actually an image, so you should be able to flash it with whatever tool you like, even with "dd".

BTW, where did you get the OFW to flash it with SPFT? And which version is it?
[Upgrading, Modifying and Unlocking] dmilz:
Thanks..

Found it from a certain site as I was googling..

TB3-730X-160707..

ANDROID 6.0
[Upgrading, Modifying and Unlocking] 0xAF:
If it's OFW, please share it, it could be usable for OTA later.

EDIT:

Or do a full OTA and then backup it and then share it ;)

But do not root before that (if you're going to OTA), otherwise it wont be usable for future OTA.
[Upgrading, Modifying and Unlocking] dmilz:

Hi 0xAf,

Thanks for your earlier responses, I've had a play and now want to return the 730x back to stock. I downloaded the .7z file for the original firmware and also the SP Flash software. I then followed he instructions but everytime I try the tablet either boots up, nothing happens or I get the error message: BROM ERROR: S_BROM_DOWNLOAD_DA_FAIL(0x7D4)...

Any ideas how to resolve this?

Thanks in advance

Hi, I'm not sure what the problem is, but my experience with SPFT is not quite good.

I prefer the fastboot way, when it's possible.

You can wait for [MENTION=6488648]dmilz[/MENTION] to finish the upload and try with his rom.
