Lenovo tab s8-50f : Unique problem - Android Q&A, Help & Troubleshooting

The tab was used by a school, so they had their software in it that uses only their Launcher and
BLOCKED EVERY ANDROID PROCESS.
The USB-Debugging mode is NOT ON so could NOT USE any FLASH TOOLS or FASTBOOT.
Using HARD RESET and WIPE-CACHE does NOT SOLVE THE PROBLEM.
Need to Install Original FIRMWARE using SD-Card, so firmware needs to be in .zip format.
How do i do it?
Please HELP!
Thanks in Advance!

[Q] Garmin Asus A50 Dead

Dear All
I'm a new android user, I just get a new A50 from Australia and try to root it. It's successful with z4root and I try to install Thai font to system. Unfortuantely I did wrong by deleting font folder in the system, therefore I can't run the system again. When I power on, it still have only garmin asus android logo and can't use it again. Does anyone please let me know how to restore or resolve this problem, or I have to throw it away? Thank you in advance.
Cheers!

Android 1.6 or the new 2.1 Eclair update?
It's a new Eclair 2.1 update, is there any solution?
Connect it to your computer via USB cable.
Using ADB, try this:
ADB REBOOT RECOVERY.
If it works, a yellow triangle appears with the green android guy.
Hit the HOME button. A menu appears. Use volume up/down to move through the options. Tap power to select it I beleive.
Reset/wipe to factory is one of the options.
If you need it, ADB is found in the Android SDK.
If that doesn't work, try calling in to Garmin for support.

Dear Spazmogen
Thank you for your suggestion, but I'm really new with ANDROID.
I downloaded ANDROID SDK and try to install but it dodn't work.
I use Win 7 64bit, do I need another software to run this command.
If possible, please let me know some previous post that already teach for beginner.
Thank you in advance.
Cheers!

ADB is a command line tool. But you will have to get Android SDK installed on the computer 1st.
Read the instructions for installing the SDK here: http://developer.android.com/sdk/index.html
ADB commands: HERE.
Interesting. I got into the recovery screen using the Quick Boot app,used the home button to show the menu. The arrows and volume buttons move, but can't actually do anything. Probably related to missing files that are reported in the data/cache/recovery folder.

official 2.1 update came out today for USA GARMINFONES. Not the A50 Nuvifones elsewhere in the world...
Is the update different from the leaked one?

I am waiting for an answer to that question myself. I have no plans to change from the leaked version Garmin posted in mid-November.

Apparently someone did a bit comparison and said they matched. Plus, I tried and it told me it was the same version. On the plus side, I messed up my recovery partition and recovered it using the backups I made of each partition after I loaded 2.1 (dump_image). I made img backups and tar backups of all the files in 1.6 (I am anal about backing up). Good thing because 2.1 doesn't come with flash_image.
I can get into fastboot and the driver loads and stuff, but I get no devices listed when I do fastboot devices command. Next stop is Ubuntu
I know it works,just need to know how to get to it. Btw,I tried both the Garmin fastboot and adb drivers as well as adding the device hardware id's into the android drivers and neither worked.
I also need to find out if there is a similar enough kernel that I can use to get a fully functional recovery mode. I did find out that you can use adb just fine in the stock one and it loads a serial driver as well.
any possible way I could get that backup you made? I apparently didnt save my backup to the pc. And currrently I messed up permissions on my Garmin trying to get recovery working. I cant run the update or anything.
I've just stumbled across this forum post from google, I too am need of fixing my phone. All that is faulty is that the recovery mode has been overwritten with an incorrect one. Is it possible to extract the recovery image and reflash it from the optus supplied Android 2.1 006-B1130-00.update file?
Or is there a way of just getting say Rom Manager to work some magic for me?
Yes, it is possible... would be easier if someone could just use dump_image on a phone that has a working recovery mode and root access. I can provide the dump app and instructions.
Where can I get the Optus update, and are you positive recovery works on it? Does it also have working fastboot?
And to the other poster, which partition do you need? Btw, Rom manager has a permission fix mode. I can get you a tar file if it is the system partition or your choice of img or tar for the others.
And to everyone, after updating to 2.1, do a master clear because a lot of 1.6 apps are left over... duplicates.
Also, odexing all apps speeds it up a lot, with the caveat that you have to re-run the odex.sh file (found somewhere here and modified by me to be more thorough) after every app update or you will get force closes.
Oh I just reflashed the update again, and I got my recover menu back!
I'm not sure if i need any help anymore, but thanks for your offer of help merwin.
By working, do you mean that you can get to it with a hardware key combination and can actually select items?
first of all ,i 'm sorry for my english .my a50 is dead too.i also delet font folder and i use the adb command 'adb reboot recovery'.but the error is device not found. and my pohone can not boot .it stop at the android guy . how can i setup the device..Q.......Q......help me ..pls

Micromax Nitro 2 E311 - Privacy Protection Password Issue - Urgent Help Needed

Hello Friends.
I have Micromax Nitro2 e311 model. Few days back my wife put Privacy protection Password on device and forgot the password.
I searched for the solution over the internet and did a hard reset from recovery but ended in losing data.
The issue is when i switch my phone on it asks for the same password. I think it is anti theft password.
I then google for flashing the stock rom which i downloaded from somewhere. I installed adb drivers and other drivers suggested in search.
But the issue is my laptop is not detecting the phone.
Please guide me i can recover my phone or not.
If possible then please provide step by step procedure.
Download sp flash tool, and run it.
Assuming that, You should have already downloaded stock firmware....
Unzip the stock firmware on desktop.
From SP flash tool... Go to download select scatter file to flash.
Connect your mobile to PC without battery by holding volume down or volume up. Once the process completed it will be ok.
Don't forget to un tick the pre load part after selecting the scatter file otherwise you may lose IMEI no. Device will not work.
Caution
1. Firmware must be of same model.
2. Pre load un tick while start download
3.. Some cool mind.
What is size of that scatter file or stock rom

Teclast P70 3G C2B7 backside camera not works

I have this tablet and there is no way to make it works the back side 2 MP camera. The android camera app do not have the selection button in the panel that allows to select front/back camera, so only front is showed. The at boot internal testing (in chinese) accesed with Pwer+vol(+) only finds frontal camera, and test it well, but back side camera is not available. Mtk engineering app says that sensor is not available, when trying to test the camera. I have done a restore to defaults from android settings menu, an also a restore to defaults from Recovery menu at boot, but no luck. My Compilation number is V1.01_20150122. I have tried to download a Baidu archive called Taipower P70 3G eight cores (C2B7) -Android4.4.2-V1.02.rar that seems to be the 1.02 version of my tablet, but I have no way con sign a Baidu account, so I can not download it. Any help?
more thoughts...
With the help of the chinese aliexpress shop, I have downloaded the firmware file P70 3G八核 %28C2B7%29-Android4.4.2-V1.02-51FE.rar from a Biudu account that seems to be an upgrade from my current one. Tha bad news is that the file is corrupt in the main component system.img, render it useless. Also includes the flash tool Mediatek SP Flash Tool v.5.1348.0.100 that seems to be the utility to flash the new firmware, also seems to have a read folder able to read internal memory from tthe tablet, but I am a noob and do not want to break nothing using it.
Hi again. I have finally downloaded a right copy of the firmware, using Internet Download Manager to download it from teclast webpage www.teclast.com/tools/pad/putcode.html . Selecting my tablet model, and using my Baidu account. But I have a question before upgrade the firmware. All tutorials for using Mediatek SP Flash Tool states that the battery of the device must be not plugged, but mine is as usual in all tablets, soldered. I think that the right process mut be using the tablet off, but in that way is not recognized by the computer using Windows 7, and tablet only charges its battery. If I connect it with power on is recognized as ADB Android Composite Interface. A curious option is Reboot to Test Mode, then is recognized as ADB Android, but without android running. What will be the best option to proceed to upgrade? The help file includes does not say nothing about it.
root and more problems
Things worsen everyday. Desperate for a solution I try to root the tablet, I found Iroot PC sofware that roots the tablet easily. So I installed other android app that works fine in my LYH M10 MTK8382 quad core, those are busybox pro, Link2SD pro, ES file explorer, SuperSU Pro. But after Busybos install the wifi connection loses and no more wifi was available since then. Wifi find access point (two wifi routers with WPA encription) but stay in connecting without getting an IP. I deleted wifi access points and look for it again, then put the password, but the same happens. The more I have is Getting an IP.... but disconnects without a connection. I have heard about delete /data/misc/wifi/wpa_supplicant.conf , but I not try it yet. The very bad new is that in my desperate, I used Recovey boot menu, and make a Wipe Cache, and also a Restore to defaults, and I am not root now. I try to re-root the tablet with PC software root, but no luck, mainly because there is no wifi to support the process. I have downloaded Iroot.apk and let it try asap, but if it depends on wifi, I am going to be in the same situation. Any help?
Plea for a update.zip for Teclast P70 3G
I would like to have a update.zip file to update my Teclast P70 3G using recovery ability to do this. This is mainly because no OTA update is available, and no way to update thru USB cable using MTK SP Flashing tools, due to the impossibility of putting the tablet in flshable mode. Any help wellcome.
Smashing success!!!! I have managed to flash the firmware. So simple, connect the tablet after you push Download button in MTK SP Flash Tool v5.1352.01, because the included Flash Tool in firmware is obsolete and not works at all with the files (scatter and so). Then the tablet itself stabilize Prelodad driver an charges the new firmware. Of course, new firmware activates the backside camera, and now works flawlessly!!! Indeed the Unknow Error from auto update app from Teclast is now a "Undiscover new version" that at least says that OTA is possible, but no one is ready now. Solved!!! Cojonudo....
This is the firmware and the procedure to make the flash in a help file. Sorry, but in spanish, castellano para que ustedes lo entiendan mejor. Enjoy,

Iconbit NT-1006T Help

Hello, sorry for my bad english, I'm from Germany.
I have a Iconbit NT-1006T from my Dad, and it stucks at the Boot Logo.
The only thing i can do with the Tab is to boot it into Recovery mode.
But in Recovery i can't do anything. ADB Connection doesn't work, wipe cache and data doesn't help.
I want to backup the Data (if its possible) and flash a new firmware, but doesnt find any firmware files.
Perhaps someone can help me, to solve my problem
Edit:
I did a little bit process. I found some Firmware files on files.iconbit.ru including the Software (Action PAD Product Tool) to flash.
Now it seems, that my Computers have problems. I tried to connect my Tab with 2 Computers and 4 different USB-Cables, nothing works. Also a different Tab won't connect with my PC. I also tried different OS (Windows and Ubuntu).
Please help...
