Help needed with bootloop - General Questions and Answers

Hello there !
Friend of mine gave me a tablet, which freezes on a MEDIATEK logo.
There is no information about model, the owner sends me via viber some images of a web site with useless information, i don't know if it is true.
The info is: CPU MTK 6796 10 Core, ram 6 gb, rom 128 gb, OS:Android 8.0, res. 2560*1600 pixel, etc...
I can enter into recovery mode, it says ALPS.KK1.MP1.V2.10.
there is options apply update from ADB, sdcard, etc...
I have tried wiping and factory reset, apply update from sdcard too, but no success (adb returns error message, go to update systems and after that immediately something wrong and error message).
Can anyone help ?

Re-flash tablet's Stock ROM.

I don't have any ROM, this is why I am searching help

Request it from manufacturer if you can't find it in Internet.

This is the problem - I don't know any information about the tablet, no manufacturer, no model.
Is there any custom ROM I can use or only PRELOADER fix ?

Maybe you can get more information by getting the vendors (boot)-image and peeking inside it; if you can get inside fastboot-mode.
You can get it by "fastboot fetch vendor_boot <out.img>""
Then do the mapping (http://www.microhowto.info/howto/mount_a_partition_located_inside_a_file_or_logical_volume.html) and mounting it.

[Q] android tab 10 help

hello,
i ve' bought a tab from ebay. i don't like how it moves and tried to install an other image. searched on few forums, but can't find any good help.
pls help me with a custom image that work on my tablet.
here are the info's from "about device":
Model number: Android Tab 10
Kernel: 2.6.32.9 [email protected] #137
Android version: v 2.3 2011-09-01 (001112)
Build number: FRF85B
tried to install Tim6a or other from SD, but the tablet won't enter in recovery mode. the tablet i see that is rooted (or not?), tried many combinations (power+vol up, power+menu, etc), but no luck.
installed superuser, received the message su is outdated, tried to update, but say "seems to have write permission on system like s-on". how can i s-off? with unrevoked forever?
pls help me, because my wife is very uppset of me spending a lot of time with this tab to "tune"...
thx.
calin.
p.s.: is the model with only one tf card slot, 512m ram and 4g hdd (SD CARD)
nobody?
ok, i answer myself: if you want to enter in recovery mode, press "home+back+power" it in couple of seconds you will see a message to tell you to push the right combination to enter in recovery mode in less than 5 seconds; this combination is home+back. then you are in recovery mode.
btw, i'm stuck here: entered in recovery, tried a lot of rom's (tim6, flanflingers, etc) in a lot of formats (android folder, separate img files, 2 firmware files, etc) but allways receive a message: "extracting data failed, please check your zsys.img".
where is the problem?

[Q] Updating ROM for HDC Galaxy S5 G9000

I have purchased a Chinese HDC Galaxy S5 G9000. It is a dual sim. From the start only face camera works. The first sim card is recognized by cannot place a call with it. When calling it does not dial and then hangs off.
I contacted the Technical service of the company which sold me the phone, and directed me to update ROM and flash tool. Unfortunately their flash tool works only with Windows (which I don't have), and everything is Chinese (which I don't know). I have tried to update the ROM using recovery. In the menu there is an option to update from sdcard. When I use that option and select the new ROM it starts "updating" but after a few seconds I get the message "updating (or operation, not very sure) aborted".
I have tried with ADB (on Ubuntu 12.04). I have succeeded in rooting the phone using fastboot. I have also managed to flash boot.img. But when trying to flash System.img, it takes hours, and at the end I get the message "Failed.... can't find device" or similar. And here I cannot see the device until I remove the phone from the computer and put it again.
I have also tried to update the ROM using ROM manager. But I get the same message: "operation aborted"
Can any one help
Thanks in advance

Hi,
Flashing from recovery is generally not an option
SPFlash tool is available for Linux - I can't post a link but check the forums (thread 2650125) or google it up.
There are heaps of stock and custom RoM's over at needrom dot com .. and most of these have great instructions on how to flash for this phone - Just search for G9000.
Good Luck

[Completed] [Q] touch not working, cannot flash img .... bricked tablet?

hello everybody...
i have a (spanish jazztel) i-joy 10" tablet, cortex a7 quad core.
i made a mess with titanium backup and when tried to recover factory settings i realized that i had screwed the recovery data.
system would boot up, tablet would work but with many errors and "stopped working" pop ups.
i looked for a stock rom just to find out there is NONE in the WHOLE INTERNET!!!
then, googling here and there i read about some compatible roms, from allwinner, kalley and other chinese brands.
i downloaded all img files i could find, i flashed them correctly with phoenix usb pro, one after another.
first two worked well except for the cameras, that wouldnt work.
then i tried ICOU10GT firmware, flashed correctly...but touch DOES NOT work, i cannot go any further from welcome screen since the touch screen is not recognized.
i am 100% sure is not a hardware problem, all physical buttons work, screen works but not touch.
since i cannot reach the "enable usb debug mode" option i cannot flash any other img.
when entering recovery mode, if i choose update from adb the tablet is not fully recognized by windows (driver says device cannot start).
i´ve tried sd burning with phoenixcard but doesnt work either, tablet doesnt boot up from external sd card.
is there any way to recover this working-but-bricked tablet?
please help!!!
------------------
if there is not....is there a 100% safe and sure way to commit a "perfect murder" with the tablet to send it to post-service and being able to claim "it just stopped working" and them not being able to see i flashed it? i guess you know what i mean.

[Completed] YonestopTech BS1078 Problem

Hi all,
I have a Yonestoptech BS1078 (ID from motherboard), also designated (Q102 in About Tablet) It's a 10.1" tablet with the quadcore Allwinner A31S chipset
the device came fully rooted. Firmware is stock as originally supplied.
The original recovery I found virtually useless (a known problem with this device), so I looked for a custom recovery on this page ...
http://www.slatedroid.com/topic/106714-twrp-271-recovery-sdk3x/
I flashed TWRP with the the first one on the list flashed via a terminal on the device
... WRONG !, recovery was oversized and totally unusable, the only two buttons I see, Install and Backup do nothing. That was the first mistake, second
was that I never tried to reflash with any of the others. I was told much too late to be of use, that the one for Fusion5 xtra works well on this device.
Next BRAINFOG, sometime later, and the faulty recovery half forgotten, ... one of the main use of this family tab is for downloading and reading our morning
newspaper ... we started having problems with the app, tried a reinstall of that which wasn't the full answer, so went for factory reset of the tab ...
WRONG again, as you'd expect the device rebooted into the faulty recovery, and stuck there, and that's exactly as it is now, each boot up is into the recovery
and no further.
I downloaded the stock firmware from ...
http://vondroid.com/resources/q102-a31s-tablet-stock-firmware.493/#.VbJdsrXppjo
All attempts to flash this have failed, I've tried with Livesuite, Phoenixsuite, PhoenixUSBPro, and Phoenixcard
I should add that device shows correctly in Device Manager as "Android ADB Interface", so I don't think drivers are a problem
I've tried to reset using Android Multi tools also GpGTools ... no joy
Last thing tried was to flash fastboot for Allwinner devices from
https://bugzilla.mozilla.org/show_bug.cgi?id=1026963 ... no joy either.
From these results I suspect USB debugging isn't enabled, but can't be sure if I ever looked at that when the tab was working.
I do read that Allwinner devices are virtually unbrickable, whatsay Guys have I created a brick with this comedy of errors ?, is there hope ?.
Re. my capabilities I have a little experience of adb, and rooting tabs phones etc. I'm no expert, but can usually follow instructions.
Apologies for long post, thought it best to give the full story. ... J

Please help:bootloop Iget Blackview a7 (eu gold version)

Hello everyone,
as its said in title i managed to f*** up my device and cant get out of bootloop.
to explain more ill give some hopefully inportant details:
This was my first root attempt ever(meant without apps like kingroot,kingoroot etc.)
I succesfuly got to unlock bootloader and with fastboot i achieved getting TWRP on it,
after change of twrp language i rebooted the phone(the tutorial i read said to do it)
This is the part when i start to f*** up
My phone rebooted and said :
*Orange Code:
Your device is unlocked and can`t be trusted
Your device will boot in 5 seconds. *
... My first idea was that maybe i was supposed to lock the bootloader back so i did that,that resulted in red code with similiar message about something being off and phone rebooting,so i unlocked it back cause orange > red ,then i googled and discovered that i was supposed to delete all of my data n cache to make sure,so i tried,i got some text about success with cache but data failed with text that it cant find this folder,so i tried to reboot like it didnt said anything about failing(this happens in a lot of software and still manage to somehow workout so i told myself this was the situation),what didnt happen?Orange code again,so i started panic,searched how to restore original rom through fastboot,got some tutorial again telling me to download original rom and file after file flash these,so i tried,it worked until i got to boot.img file,it said that it wasnt boot file at all,so in pure panic and desperateness i procceded to download some recovery.img file in hope that this will do the trick and the original bootloader will recognise it and let me back to my phone,well that was terrible,terrible mistake,now im stuck in bootloop(orange code),cant get into recovery or fastboot by any key shortcut(i tried all i could find up+power,down+power,up+donw+power,just power,nothing works,only thing that happens is that after some time it just shows boot logo and is stuck there)so im desperate,my pc doesnt identify it,fastboot doesnt too,not even adb)so i ask here for help with my sincere pleading and thanks.
Disclaimer:Im sorry if there are some mistakes in text english is not my main language and its my first try to ask for help on technical forum so i hope i didnt done something wrong
Edit:i achieved getting to normal boot logo (seems like kind of random thing will try to get more info how,and in this state its just stuck here doing nothing but device manager recognise it as A7 as it would been normally plugged in exept giving warning (Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)),so that could maybe help that pc recognise its being connected but still nothing further,no fastboot no adb,no sp flash tool
