Hello everyone,
I bought this tablet on ebay and it seems that the ROM preinstalled is a test ROM.
I searched the web to find a custom ROM but I couldn't find much info.
I found the way to root the tablet but that's all.
Is there anyone who can indicate me a link to a stock rom or a good custom one?
Thanks for those who will read and help!
What do you mean by TEST ROM?!!! this is ridiculous, I have the tablet and it's working like a charm even I received over air update yesterday, the only odd is that I can't use it as a phone because Lenovo has no license yet for that it's available only in the Chinese version, and I think this will be solved later when they start launching their mobile phones all over the world.
Hello mmis,
Test rom is not the correct terms but I didn't know how to call that !
The problem is that every widget I put on the desktop is loading but never display anything.
The information in "About tablet" are the following :
Model number : IdeaTab A2107A-H
Android Version : 4.0.3
Baseband version : MAUI.11AMD.W11.50.SP.V13, 2012/05/25 01:09
Build number : A2107A-H_S307_120605
If I search for system updates, it doesn't find anything. If I click on firmware update, the settings FC.
I made a factory reset but no luck.
That's why I thought it wasn't a stable version.
As long as you tried the factory reset with no luck, I think in your case its better to get back to Lenovo customer service or your local dealer if it's under warranty, they should be able to help you. it's a new device in the market and it will be difficult to find custom ROM for a while or even someone to give model-specific help. Good Luck
Would you mind linking to the instructions on how to root this thing?
Sure, no problem !
After several hours of search and difficulties to register onto Chinese websites
I managed to find the attached file. I take no credit for the tool because it was developped by someone else (SNARL I guess)
It was missing the superuser apk inside so I put it back and also translate the steps to English.
Here are the steps :
- Connect the tablet in Debug USB mode
- Launch root.bat
- The device will reboot at each of the 3 steps
If you need more info, don't mind to ask!
Here is the link of the original thread :

Fantastic, thank you very much.
LePad Chinese Model A2107A-H
I have a Chinese issue model of the A2107A-H that has the dual sim card cellular feature. I've been trying to get it rooted to get rid of the Chinese apks on it, but normal rooting software has not been successful so far, including the one posted here from SNARL via Ichi go's post. I get a "device not found" error message and in device manager on my PC it indicates that there is no driver installed for the device. I have "debug" turned on and the USB link seems to be working as I can see file folders on the device, but the rooting software will not run. I've tried several of the most well known methods with no luck. Any ideas on this would be appreciated and in particular, if there is a driver I need to have installed to get the rooting software to work??
TIA!!!
Rob
First of all many thanks to you ichi go it was very easy to root this device as instructed, but as the one I have does not have the phone calling capability, I replaced the phone.apk with different one but now the device does not recognize the sim card at all, I tried to push many versions of phone.apk to system folder with no luck, it seems even if I put the apk in the system folder the device will not launch it at all, could you please help me in that.
I've had this tablet for a while and love it. I just got the OTA update and its downloading now.
I'm a also keen on rooting it and inns installing a custom ROM. I guess once its a bit more common, we can expect a dedicated Dev community here on XDA
The update failed to install. I'm not rooted or anything but upon restart it gave a signature verification error.
Any way to fix this?
Edit: got it! was a path error since i had changed the default storage.
but i can't figure out any changes

How does your device appear in the device manager? For sure, the adb driver isn't installed. If it's not the case, download android sdk and then the Google USB driver in the extra section.

FM Tuner - perfect for in-dash?
The in-dash car tablet people should be happy to hear the A2107 has an FM Tuner. It's one of the few tablets that has a radio tuner, and the only modern 7" that I know of. I just ordered one. I will report back.
The Chinese stock rom I installed has the phone ability and that works very well! The problem of this stock rom is that the Google services aren't there. I'm trying to find a way to install the zip file but I need to know the exact path of the recovery partition.
I tried to find it with the cat /proc/emmc command but this partition isn't listed.
If anyone has an idea...

So I understood that you managed to flash the Chinese stock ROM, am I right?!! please tell me how to do as I am facing serious problems with my device, I managed to root and then I changed the phone.apk (what the hell I was thinking of) and now I have the the error message android.process.acore stopped working and sometimes the sittings force closed, I tried to re root, factory reset and deleting cache of almost everything with no use, even I contacted the Lenovo CS to reinstall the original firmware, I think they will charge me for that :crying:
by the way I don't have contacts anymore (I installed it manually) and the most impressive thing that the device doesn't recognize the SIM card (I cleverly deleted the original one phone.apk :silly and what ever apk I push into the system/app folder and change the permissions it will not install after reboot.
So...what do you think guys?!! any help?
I've confirmed this does work on the A2107-F.
I had some trouble with the ADB driver. I can't post links, so you will have to google it, but I used adb_driver_20110720.zip for the drivers. I forced it to install via Update Driver > Browse my computer > let me pick > have disk > pointed to the android_winusb.inf file > selected the thinkpad option, it was the bottom of the two.
I also had to manually turn the tablet back on after the first reboot, but it went fine after that.

Hi mmis,
I will upload tonight (if i have the time to) all the needed files to install the Chinese ROM (tools and procedure included).
Btw, I managed to install all the Google services and all is working well! The only thing is that the OS can only be put in English. All other languages are Chinese variants.
Hi I just flash tablet with a chinesse rom A2107A_H_S121_120525 and right now the device don't turning on anymore. The flashing is still possible. So I need a stock rom please
I have an older Hipstreet Flare (1) HS-9DTB4-8GB which worked fine for the past years. And before someone says it; yes, some might consider it as a China knockoff.
The device is rooted by default. I can for example write files into / via ADB. A few weeks ago I tried to install busybox but it ended up in a loop. So I deinstalled it and could continue working.
Next time I booted all was in Chinese, with the main screen having no icons (links to) apps. In the secondary app menu only default apps were there, none of those I installed over the years. Still the SD card directory (is all internal though) was unaffected.
Listing the file system of the underlying Linux showed most files with a date stamp of 2-1-1970 and a few with 2013, the year I purchased it. I still could create files there via ADB. Could also install apps and set it to English again. But the next time I booted all this was forgotten (apps and files I created gone and it was in Chinese again).
I used volume-up and the power button to get into the (what ever you call it) and selected "wipe data". Rebooted, set it to English and rebooted again. But again it came back in Chinese. Same when I used the menu "Backup/Restore".
Assuming the firmware (rom?) was damaged I was also contacting the Hipstreet support. Who were friendly but also only told me to wipe the data into factory reset. But I did this already several times, see above. They also couldn't help with firmware.
Before I throw it away. Does anyone has any idea what I could to? May be with suggestions taking in account I am a Linux user on my PC (no Windows or Mac installed here)?
Does anyone know if phones (like this) store a copy of the firmware somewhere? If, what's the file name? default.prop?
Thanks you.
Hello all. I am new to the forum and I do not speak English. Helping a google translator.
I have a phone Allview x2 Xtreme and a small problem.
I root my phone out of your forum and I fell android system, so I downloaded the go with your forum and installed. everything went without any problems with one exception. My problem is the inability to save any files to the phone memory. Downloading various applications from Google Play but do not sign up and grind endlessly. Factory settings restored more than once and not washed your any positive results. It seems to me that after installing rom should create folders, unfortunately, nothing. Computer and telephone see partition, but you can not have any utorzyć folders. Please help and sorry for my language.
Something else I noticed. On the phone memory is formed TWRP folder and no other can not be next to him to create. But in the middle of TWRP you can create other folders may help. Or YWRP adapted at each other partition memory and therefore does not see the android. Please help phone admittedly under warranty but with us is how to give the equipment to the site takes a long time to repair.
I'm having the same issue... currently looking for a fix. Seems that TWRP is incorrectly formatting the device.
OK, I had to utilize the Gionee scatter file and stock ROM in order to get the phone partitioned correctly,
I then took the BLU Scatter file and Stock ROM , boot, and recovery and flashed it afterward. Then did a factory reset. Took updates then rooted, again. You are left with the Gionee splash screen... But that's an easy fix.
Appears that the versions of TWRP posted DO NOT partition the phone correctly and writes a TWRP partition that screws everything up.
I will post links or you can find them yourself in the meantime. They are all on xda mainly on the thread about rooting... Odd thing is. Phone seems to run better than before... I would have left the Gionee ROM up and running if it wasn't 4G only... I'll post links later.

Hi Im not a developer and dont know much about android i just don't know who to ask for this particular problem.
I had a ZTE Obsidian phone that wont get past the Metropcs boot screen so I did a system restore menu by holding power and the up vol button.
After going to boot menu I created a backup to my sdcard. userdata_20150101_003623.backup this is the file name I was given. To make sure I created another one and the only diffrence is trhe file extension saying backup1.
I then factory reset the phone and tried to reboot but it still has the same problem. I purchased a new phone the asus Zenfone3. I then tried to do the same thing here but restore the phone using the same backup from the ZTE but I received an error saying the backup is out of date. The zte was running on lollipop and the asus on marshmellow.
Im on windows 10. I was hoping to find away to extract my contacts and possibly the app color note with the notes I wrote in it from the backup.
Is this possible can I extract these files from a .backup to my windows 10 desktop some kind of way or can I get another zte phone and create a clone of my last one from the backup file
Greetings and welcome to assist. Do you know what format the backup was saved in ? Where you using twrp or cwm? You could use titanium backup to extract from the backup on your phone if you have root or I think assayed kitchen has the option to extract from a back up here

Do you know what format the backup was saved in ?
No I dont know what format the file is saved in. The file extension just says .backup
Where you using twrp or cwm?
Im a novice at android and developing. I dont know what these are. I used my no rooted phone from Metro Pcs (ZTE Obsidian Z820) before I factory rest it I created a backup using the factory restore system on the phone. I did not use a computer or third party apps to do this.
You could use titanium backup to extract from the backup on your phone if you have root or I think assayed kitchen has the option to extract from a back up here.
The phone was from metro pcs and not rooted. I have also downloaded the (Assayed Kitchen) program but have no idea how to use it to access the .backup file. There are no instructions for some one of my limited knowledge on android phones.

Greetings ans welcome again. It is unusual for a stock recovery to be able to make a back up that is the problem, it is only normally possible to make a backup using a custom recovery like cwm or twrp so I assumed you had done this. You can not restore a backup from a different model of phone as it is incompatible, if you copy your back up to your pc and right click it to get properties it should tell you what file extension was used. You won't be able to restore the back up to a different model of phone but may be able to extract contacts, messages, photos etc

Yea thats what I thought but wanted to verify it. Im currently trying to find the same model phone online so I can use the files.
When I click the properties button the file type is listed as "BACKUP (.backup)". I dont think there is a program that can actually read this file type at least I cant find one that does.
If there is one I would like to be able to get that kind of info off of it.
This post is to help users who have accidentally or on purpose tried to upgrade to Android 6.0 on their Kiwami Samurai FTU152D using software for FTJ152D (Japanese version of phone), and to help with root and installing Xposed on your phone. There is a risk of getting the phone stuck on boot screen if a user uses certain versions of SuperSU. If you searched the net and found this thread, and are still on Stock Rom for your FTU152D, Do not Upgrade until you have read this thread. Upgrading by flashing a rom using SP Flash Tool you risk losing your IMEI information in the phone forever. I am going to write this thread with an assumption that reader has upgraded the software in their phone using the Japanese Firmware. You can read through and use this thread based on your situation and if confused, better to ask questions on the thread than trying something on your own. I do not take any responsibility if you brick or hard brick your phone, so please be careful and do not just randomly flash things without full understanding, confused? ask questions.
Note #1: First and Foremost, Be careful to not flash a preloader.bin file in your phone from other phone models. You run the risk of permanently bricking your phone. Use the correct preloader made for your phone.
Note#2: Make at least a 5 GB backup dump of your phone using SP Flash Tool 'Read Back' tab before you attempt root or other customizations on your phone. This can be done using the scatter file from stock rom of FTJ152D Android 6.0 available at needrom website at:
https://www.needrom.com/download/freetel-samurai-kiwami-ftj152d/
You will need to input scatter file in the download tab before SP Flash tool will allow you to do a 'Read Back' dump of your phone. Be very careful when attempting this and do not accidently download (the whole reason of this thread and my troubles is because I did exactly that). In 'Read Back' tab, you can click on 'Add', name the raw dump, and add the starting address (that will be 0 of course) and make the length equivalent of at least 5 gigabytes, make sure that you have selected the 'EMCC_USER' as your region. Use 'Add' to add another 'Read Back', this time for preloader (in boot_1 region). You can open the scatter.txt file from the rom you downloaded earlier to see how long this 'Read Back' needs to be. Next, click on 'Read Back' to start the backup dump, power off and connect your phone via usb to the computer. (You may need the VCOM drivers, if the phone is not detected by SP Flash Tool or you keep getting errors, search for the driver online or download it from the needrom website, same page where the rom is (link above). Keep these two dump files safe as these are effectively your backup in case you mess up your phone.
ROOT and Xposed:
If on lollipop there are at least couple of options to root using kingroot (personally dislike) and others. If on Marshmallow, you can use my posts in this thread to root using Magisk:
https://forum.xda-developers.com/general/help/how-to-root-freetel-kiwami-samurai-t3610015
Recover from Japanese firmware and/or Going back to Lollipop:
In case you have flashed the Japanese firmware and now have problems using the phone and want to go back to FTU152D stock rom (Android 5.1) with correct baseband, use the attached file (mega link below) with SP Flash Tool. First, find an nvram.bin file online compatible for mtk6795 chipset or look at this page as you can download a nvram.bin from there:
https://afterroot.wordpress.com/2015/07/22/mtk-restore-nvram-bin/
***Very Important Note*** Nvram.bin file as the one on the above website will fix your phone, especially the baseband (all the better if you made a backup using the method mentioned in Note#2 above, you can use the scatter file and hex editor (such as HxN from download.cnet.com) to cut out the nvram.bin and secro.img (need both to restore imei and baseband) partition file from the raw dump) but the IMEI numbers will be specific to the nvram.bin file you use (and this is why i didn't provide my backup nvram file, but i did provide secro.img as it contains baseband info), and using wrong imei number with your phone may not be legal. If you use the file from the above website, your IMEI numbers will be specific to that file and you MUST change your IMEI numbers to your original numbers using a number of apps or other methods available online, just search the web.
You should unzip the rom zip from this link:
https://mega.nz/#!1v4GUaBC!Wj4JW6fZkxNB-ZISrdPmBcR_hu_XSu9NoCrnOKYMdYo
that I put together by dicing raw dump of my phone using SP Flash Tool and putting together some of the files from the MM folder. Some of these files may not be needed for a successful installation but i just wanted to be sure because I had issue with some folders not being visible in the phone's internal memory. Make sure you insert an nvram.bin file in the rom folder before proceeding otherwise your phone sims will be greyed out, choose the scatter file in the folder with SP Flash Tool download tab, and use 'format all + download' option in download tab, click on 'Download', power off the phone and attach to PC via USB cable. Once download is done, power up your phone and you are done. Now you can root and install xposed, and fix your IMEI numbers if they are wrong using the tips and link provided above if like.
I am trying to get a custom recovery to work with this phone but so far because there is no touch in recovery mode, TWRP doesn't work. If anyone have been able to install or use custom recovery, please share your experience and help out others. Thanks.
If anyone have internal phone storage not showing DCIM, Alarm, Ringtones, and other folders, make sure you don't have an SD card in the phone, do full factory reset after flashing, go to storage settings and make sure the internal phone storage is selected for write to memory, then insert SD card in the phone. That fixed this issue for me. It is just how this phone is setup that you have to select internal phone storage or external sd card for where the stuff gets stored.
Another fix that worked for me was to remove SD card from phone, format whole flash except bootloader in format tab first, flash all files except userdata.img and cache.img in download mode, and then make sure you go directly to stock recovery at first power on (hold volume up while powering up the phone), wipe cache and wipe data/factory reset, and then allowing the phone to boot up the first time.
Another tip for other Kiwami Samurai users i wanted to share is that both Freetel roms (5.1 & 6.0) come pre-installed on either variant of phone with 3 potential malware or PUPs that i just detected using Malwarebytes (see screenshot). I wouldn't have expected this from a Japanese smartphone manufacturer. These are installed as system apps and require root and an app like Titanium Backup to freeze and/or remove these. 'Debloater' app by Gatesjunior on xda forums can also remove these.
Thank you for the thread.
I have this phone, the US version FTU152D.
From what I can find on XDA and other places. there is no update to Marshmellow available for the US version. Can you confirm?
I see your methods above. I am thinking of flashing stock ROM to the phone to clean up some issues. Think of it as a clean install.
Thank you,
