Hi,
So I have Huawei Mediapad 7 and I want to flash CM11 on it. I fail on the first step, rebooting in Fastboot mode. I press volume up + power button but nothing happens, device just turns off and there is searching for USB drivers in the background of Windows 7. Never finds them, it says unrecognised device in Device manager. I tried with AIO but it is all the same - no fastboot mode. Sometimes I get green droid with yellow exclamation mark and message in the bottom "rebooting" and then just reboots. I managed to root it (at least hope so) and that is about it.
Another weird thing is I rooted it then made factory reset and there was still Superuser icon and .apk in the menu. Factory reset should wipe that too, right?
So the problem is that Fastboot mode which simply skips or is broken somehow in my Mediapad 7. What is a solution? Any advices?
I just have bad luck, I have another mobile phone which simply doesn't want to be rooted but that is for another thread...
Well, I own S7-931u tablet, but haven't heard of ANY custom rom for this tablet, nor CM11.
Fastboot concerned, well I didn't found the way to boot it to fastboot mode, so at the and I gave up altogether on it.
About rooting question, well I didn't test to do factory reset, I mostly do reinstall, because I have nothing to lose.. well tablet isn't worth of putting anything on it.
I can't post link but tutorial is here, just google "kitkat mediapad 7". What about that?
Sadly Mediapad 7 and Mediapad 7 Lite are different tablets, just like s7-30x is not the same as our s7-931u.

I have a problem with one of my Lenovo A830 phones.
I bought it from Etotalk, so it came rooted, and with their custom version of the Lenovo Stock ROM and their custom version of CWM 5.5 installed.
I tried formatting my SD card and then doing a factory data reset from within the operating system. (I was intending to install MIUI V5 after rebooting into recovery).
However, on rebooting, the device is now caught in an infinite boot loop, and I am not able to boot into recovery mode (by holding down power and both volume keys). It loads the initial splash screen, then shows a few seconds of the Android character and some whirring cogs before rebooting.
I am able to boot into Factory mode (power and volume up) or Meta mode (power and volume down). Factory mode has a number of options, but they are all in Chinese characters, which I am unfortunately not able to read.
I did notice that my SD card seemed to be write protected when I tried to format it in my computer and to copy on the new ROM - I solved this by putting it in a different phone and reformatting it. I wonder whether the factory reset process has write protected something it shouldn't have?
Does anyone know how I might best proceed? I've been digging around on the forums, and tried a few things, but there's nothing which seems to provide a coherent solution for this problem.
I've got the latest Android SDK Tools, MTK Droid Tools 2.4.8, SP Flash Tool 3.1312, some additional ADB drivers (120827 v3.7) that I'm not sure how to install, the latest MIUI V5 ROM (3.8.16), and the latest stock Lenovo ROM (S118 from Need A ROM, just in case I need it).
Maybe different SP Flash Tools version?
I had trouble using SP Flash Tools v3.1312 with A830. Once I switched to v3.1304.0.119 I was able to flash both the original ROM and the custom MIUI one without serious issues. I'm unable to post the download link but google it.
One other thing is that when connecting the phone, it usually loads the something something Preloader driver, which is no good (even if it gives you Download OK). When attempting to flash either ROM, try pressing both the power and volume up buttons while connecting the phone (after pressing Download), only way it worked for me.
Good luck!
I managed to sort this out quite simply in the end!
On the Lenovo A830 (and presumably other Lenovo Android phones?), you enter recovery by pressing power and then pressing volume up / down together after a short pause. The short 1 - 2 second pause is important, because if you try and press them at the same time or in quick succession it doesn't seem to work.
I then installed MIUI V5 from the SD card followed by Google Apps after a reboot. In order to get MIUI to install, I had to remove the assert check at the top of the update script, because this seems to erroneously check for the A820 (even though there isn't currently a port for this device?). It's working excellently with two exceptions - I am unable to select the SD card as a storage device, and Google Play store is not searchable (it causes a Force Close).

Hi I had similar "reboot loop" problem this morning after a phone factory reset.
I have no idea how I solved that but the following was the steps I tried:
1. Install the MTK6589_PdaNET_ADB_VCOM_Drivers. Skip the USB connection during setup. Start the PdaNET after setup finished.
2. Insert battery inside the phone and connect the phone with the computer by USB
In my case, the phone reboot loop once, and the lenovo screen appeared in the second restart. The phone hanged. I unplugged the cable, took out the battery, insert the battery again and start the phone normally again and it is working now.
I recommend installing the recovery rom after you have fixed the phone.
Goodluck
Hi, first of, this is my first post on this forum, so sorry if this is by chance in the wrong place...
Right, now the issue;
I got a Lenovo Tab A10 (model: Lenovo A7600-F. There is another set of code that goes like Lenovo A7600-F TAB A16GBE-DE)
and I have a serious feeling its bricked.
I turned it on today (at time of writing) and it gave the "Lenovo FOR THOSE WHO DO" logo like normal, and stayed like that...
forever...
So after I pushed the little white reset button besides the micro-sim slot I boot up in recovery mode by holding the volume up and power button till the black screen with the white letters pop up, and I select [Recovery Mode].
Then the Lenovo logo pops up again, and after a second or two an Android looking like he's playing very dead comes on screen with a "!" exclamation mark
above and the text "No command" under it.
I tried a reboot with the same splash screen hangning as before.
I looked up on the internet and found that clearing the cache helped a person, so I did that by pushing the power button with the dead Android and scrolled to "clear chache" with the volume buttons.
I did that, tried a reboot, but nothing happened, same result as the previous reboot.
I went as far as restoring the factory settings and rebooting but to no avail.
I go digging.
I found it could b the rom, the os or both that is totally f%#@ed up somehow and that it is in fact repairable.
Some more digging about and I find this: forum.frandroid.com/topic/203630-clockworkmod-recoveryroot-pour-lenovo-a10-70-a7600f/
Those links are very useful, because they bring me to a bunch of downloads that contain the flashing tool I need and recovery images along with a link to
Lenovo Smart Assistant. Also I can read French, so following the instructions wouldn't be a problem.
The first thing I do is connect the tab and start up Lenovo Smart Assistant (with the tab off). The computer (win8.1 Packard Bell Easynote LE) makes the chime of something
being connected, but I cannot see the device between My Computer like I normally do.
Neither does the Lenovo Smart Assistant recognise anything plugged in after a scan.
Following the instructions on how to recover with the Flash Tool also is fruitless because the Flash Tool doesn't recognise anything plugged in either.
I've now completely run out of options and don't know what to do.
Is there any way at all to save the tab and get it back up and running?
please help me this !
my Kindle Fire HDX 7", maybe hard bricked after factory reset (wipe all) ?
now, it just show "Kindle Fire" and stop here forever ! yesterday, i still turn on and turn off normally !
But today, after I tried to Factory Cable method, it's quite ! "waiting for device" show so long ! then, I turn off by hold power, and all will be : no signal when i plug in charger ! no turn on by press power button ! no connect to PC, no ADB, in Devices manager on PC, only show "QHSUSB_BULK" ???
I have read a thread on this sites, by long press power button in about 2-3 minutes, and my KF turned on and show "kindle fire" as before !
and whenever i turn off by hold power, my KF will be quite ! and PC only show "QHSUSB_BULK", to turn on, I must long press power in 2-3 minutes as... again and again !
if my KF stuck on "kindle fire", when usb cable is plugged, PC will show "Portable devices - MTP USB Device" in Device manager !?
I tried installing Kindle Fire driver, ADB driver, Android SDK... no effect ! In command prompt, I type "adb devices", it show "list of devices attached" and nothing !
I'm confused and nothing I can do ?
So, Please help me !
Thanks you !
How exactly did you perform the factory reset? What exactly did you wipe, and what did you use to wipe? Which original OS version did you run, did you root, install any recovery tools like Safestrap or TWRP, and did you use any custom ROMs like Nexus or CM?

I installed salestrap and CM10, then factory reset, i don't remember what's i wiped ! maybe all !
I tried pressing power and volume UP, then my KF show System Recovery, but only have 2 lines : Reset kindle and factory reset, i saw "Your Kindle doesn't seem to be able to boot", i choose factory reset again, and everything is stuck on "kindle fire" !
i wonder when i plug Factory Cable and try any methods, then It's get black screen and show QHSUSB_Bulk in device manager ! I reallize that it will be drain battery if i do Factory Cable methods ! that's reason make my kindle get black screen => no battery remain ! I try charge it about 30 minutes, and i can turn on normally !
i don't know why, my Factory Cable is wrong ?? i tried with 2nd cable ! I linked RED Jumper to EMPTY jumper (1 - 4, and some can different, but still with RED and EMPTY)

Do I get this right, you were on 4.5.2, rooted, installed Safestrap v4. Then you probably installed CM11 (there's no CM10 for HDX, right?) into the stock slot, i.e. FireOS is gone?
Then you did a factory reset from Safestrap v4 (this would mean you had some protection to not wipe system)?
But then you entered Amazon recovery by pressing the Power & Vol + Buttons, but without something in the stock slot that probably failed, and probably killed Safestrap, too? So you don't get the Safestrap screen after power on/reset anymore?
If that's the way it is, it seems pretty bricked to me. Dunno if this could be rescued anymore.
Thanks for
I just remember after i wiped 3 times, every has gone ! I installed a salestrap but don't know version, and CM, because i got them from my friend's PC, and he has a other KF that running well !
Now, my KF only : Stuck on "kindle fire" or "system recovery", nothing else ! No adb, no fastboot !
Poor me !

"Factory Cables" do not work with with HDX devices. This recovery technique can not be used.

With HDX you must know what version you're on, because what you can do depends on that. You must pay attention to the compatibility notes in the threads of recovery tools (e.g. Safestrap or TWRP), and the ROMs you install. Otherwise failure is what you will get.
my mistaken !
i guess it's dead !
I can not do something else ! I found everything that concerned with on google, but nothing can help me for this situation !
thanks so much everyone !

Hello,
I have a tablet that looks similar to Q88 A13. CPU is wm8801, OS - Android 4.1. So I had stopped using it and left it sit for like 1 year. Now I charged it and tried to turn on, but it wouldn't get past first logo(the one that appears first, not the os loading one) and would attempt to go into recovery itself, but then the android with exclamation mark would appear for a while and then device would reboot and so on and so on...
Then I triggered a hard reset with a button combo, but it didn't really help. Tablet stopped trying to go into recovery and simply kept getting stuck at logo.
I can't access recovery, and neither ADB nor fastboot is working. PC with win 7 reports it as unrecognized device and other PC with win xp doesn't even see that anything is connected to it.
I've tried unsoldering the battery, completely discharging tablet without it, soldered it back on, but didn't help.
Help?
bump
Try Livesuit 1.11.
I've used it to load several ROM's
I'm currently running FaaastJB v2.5 found at http://forum.xda-developers.com/showthread.php?t=2447819
Afternoon
I have a Lenovo 7" tablet which is sticking on boot...to describe:
tablet off, charge screen working fine (green battery)
can get into menu to select fastboot mode or recovery
fastboot works, at least screen appears!
recovery shows dead android/no command screen - how to access recovery?
booting up, get inital orange logo then a 'bing' and start of boot but then freezes on the second logo
tablet not visible on PC, even in fastboot mode (have installed drivers)
I'm looking to get this going but am a bit stumped. I tried reinstalling firmware but can't get SPF Tools to work with any available scatter files; I would like to install TWRP (I found a potential image file on XDA) but can't do this until the PC recognises it....and I'm going round in circles now....any suggestions gratefully received. :good:
Update
OK, post was maybe a bit premature - I've kinda fixed my issues.
Managed to get into recovery after watching many videos (most of which were wrong, but hey-ho, got me on the right path!). At dead android screen, press and hold in power + vol up + vol down together (there is a bit of knack, turn it on its side with buttons facing up seems to be easiest) - this fires up the recovery screen (android standard recovery).
I managed to get over my bootloop issue by performing a data wipe/factory reset and cache wipe, then restarted fine.
As this was a secondhand tablet (my usual purchases - good condition bootloops!) - once it booted up I got into the set-up screens only to discover a Google lock issue. I ran the FRP unlock from here: https://androidfilehost.com/?fid=11050483647474832839 using the instructions from here: http://forum.gsmhosting.com/vbb/f958/lenovo-tab-4-7-essential-tb4-7304f-frp-remove-2322527/ (Voltrans second post, not the original one which has a 404 error on the download site). This removed the FRP lock straight off and now I have a functioning tablet.
I'm probably going to try getting custom recovery on so will see how that goes - I'll post back
and...that's all folks....
OK, despite finding a TWRP recovery online https://twrpbuilder.github.io/downloads/twrp/#441 and downloading it, can I get the fastboot unlocked? no.
Apparently Lenovo locked them all up and threw away the key, so nothing more can be done here.
I tried various iterations of fastboot oem unlock and fastboot flashing unlock, and nothing works, just get an error - and yes, I did put developer options on, OEM unlocking ticked and USB debugging active.... :silly:
So, unless someone can point me in a direction on how to unlock it - I've reached the end of the road with this one
