how to flash tablet if you cant enter recovery mode

hi everyone i thought i had completely bricked my tablet but after hours/days of searching i found information about flashing by taking information from different methods for different tablets. i learned about the nand memory and about how the boot loader works. when tablet starts up the tablet boots to internal storage first that's nand then external storage sd card then adfu mode/recovery mode.But heres the problem as long as tablet detects the internal storage it will always boot to that even if its corrupt. if you were like me and you installed another firmware and lost the abilty to enter recovery mode then adfu mode and sd card then you would have no way to flash tablet. i found a way to trick tablet into skipping reading internal storage i don't know if it skipped external storage didn't have memory card. it skipped these went straight into adfu mode.

HOW I FLASHED MY TABLET THAT COULDN'T ENTER RECOVERY MODE

first i took it apart . for me it was two screws on side then used flat head screw driver to get case apart.warning the speaker inside will be stuck to back part of case so dont rip off. you can remove speaker from case if you want if it makes it easier to work with tablet open.

You now need to get to the nand chip mine and probably everyone else's is behind the big connection for the screen. if you have tablet facing down and circuit board is on the right. the top left of circuit board is a connection that goes from the screen to tablet under this is the nand chip. you should remove the screen connection by unclipping it from board you dont need the screen to use recovery. this is what the nand chip looks like. ( there was on mine a empty space for maybe another one but its the the space with a chip on left not the space without one on right)

you will notice that theres a triangle mark on tabletboard thats pin 1.

what you need to do now is get a pin or flat head screw driver ready. switch your pc on ready to do your flashing.

connected tablet to pc by usb cable.

now is the important part with pin or flat head screw driver touch pins 7 and 8. i used flat head screw driver i might of been touching other pins as well but as long as 7 and 8 are bridged then this will work

While touching pins 7 and 8 switch tablet on. because tablet cant detect nand it boots from next thing as thers no sd card it goes into adfu mode.

you need stop touching pins 7 and 8 before you flash.

if your pc dosent detect tablet properly just remove and reinsert usb as long as you dont switch tablet off by power switch it will stay in adfu mode.

you can now flash by pc.

I had to flash tablet with CEMA10S24 firmware as i dont have luck with the other two TF-20121031-Q8-0329camera.zip and PC-20121031-Q8-0329camera.zip

if anyone got other compatible firmware thats not yet listed that would be great

also i have had some luck opening .img files by using magiciso and winimage
[Android Q&A, Help & Troubleshooting] brynthomas:
here's a better pic of nand chip. more details about my flashing method it seems you need to touch pin 7 and 8 but make sure not to touch other pins just bridge those two (you won't mess chip up but touching more than 7 and 8 dosent make it enter adfu mode). you switch tablet on while touching those two pins. the tablet goes into adfu mode. you stop touching the pins. you then flash your tablet .

now to figure out how to root it .. unlockroot says no device .,. Root_with_Restore_by_Bin4ry_v18 gives random errors .. superoneclick stops at an error ..

edit!! .. got it rooted!! i followed this ..

0) Extract all the files from the zip attachment here Download gl5201-rooting zip

1) adb install <pathtofilesextracted>\Superuser.apk

2) adb push <pathtofilesextracted>\busybox /sdcard/

3) adb push <pathtofilesextracted>\su /sdcard/

3.1) adb shell

3.2) su

10) ln -s /system/bin/su /system/xbin/su (here it says "error files exists" but go on..) ***

11) Install Root Explorer, it'll ask for root permissions...give it to it !

try firmware from polish publisher. google: tracer ovo lite gt . first line in search. choose polish language, Seria OVO, Android 4.0.3 dla OVO Lite GT / Light. sorry, can't post links yet.

your tablet gs701b is the same as Tablet Q8 or my Tracer OVO Lite GP/Lite.

there are two versions Light updates v1 and Light updates v2.

one of these should be 100% with working touchpad.

I can not understand everything

Hi sorry I do not understand what happens but when I follow the steps you indicate tells me not find the device and do not have the drivers installed many times but I do not wrong. Reviewing some step by step what I am supposed to do I think the problem is when drivers and I can not find the folder c:\Users\.Android to replace the file adb_usb I have no idea what happens but not meeting as this could help me this unsettling, greetings and thanks for the help.

PD: Sorry if my English is very bad but it is not my native language sorry.

Edit: I was able to resolve the issue of drivers but now there is another problem when I try to step 2 and step 3 I get this error "Failed to copy <pathtofilesextracted> \ busybox to / sdcard: is a directory. And as this happens when I get to later steps tells me that the file is not found busybox someone can help me with this.

I tried to copy on another route and modify the script below and copy the file but in subsequent steps after executing the command line adb shell tells me it can not access the directory anyone has any ideas about how I can fix this please .

Edit 2: I have a problem is a bit strange and it seems that adb recognized my dispostivo and everything is fine but in subsequent steps to ADB Shell command line appears that the connection is lost after putting the password and others wanting to use cp throws me the error saying, Not device found and I am stuck right in that I can do it no one can help me please = S..

Is chinese skype safe to use?

I managed to root this tablet following the instruction from this forum. Big thanks to all the contributors. The immediate benefit is to under clock the cpu with no-frills cpu control to 96Mhz and overclock it to 996Mhz. This increases performance and extends battery life.

Now I have a new challenge. The installed skype is version 1.0, not the skype from google play store. The skype version 3.0 from play store got hung during log in. While the built in version 1.0 flashed on screen about using P2P protocol and works. Is this version safe to use? How can i get the official version working with this tablet.

Thanks.

no.spam.period, was your tablet a gs701b or an actual gl5201, I am curious as I am unable to get my PC to recognize my tablet in ADB and am wondering if I may have incorrect drivers. I have seen in multiple forums and message boards that these drivers are cross compatible. I have used the drivers that are linked in this thread, windows appears to see the device, but ADB will not, I am going nuts, this is not my first rodeo, so my frustration is compounded by the lack of information on this tablet, any help would be greatly appreciated.

4. hold vol +, home button and then press power button

5. select option 3. install from sd card

6. confirm selection

7. put tablet down and let it do it's thing

8. once the tablet has done upgrading turn it off and back on again and voila a working gs701b once again

[Android Q&A, Help & Troubleshooting] waderb77:
Root achieved via wifi

If some of you don't already know, root can be achieved via wifi without having to install usb drivers for the gs701b, (from hours of research I found that wireless debugging is enable by default in ICS builds) use the following steps:

Open ADB

type "adb connect (local ip address of tablet)"

follow the walkthrough steps listed in this thread

you will achieve root as long as you are using an ICS build on your gs701b w/out home button.

hi guys, I have a gs701b tablet without home button, I have rooted based on information found on the internet and all is good.

I have a few issues with the tablet I like to solve.

My firmware is dated March 12th 2013, so it's much recent than the ones found on the web so far.

My tablet has some kind of problem with memory, and responsiveness, most of the time I only have about 75mb of free RAM even if there are no apps running and the tablet does not work like it should, don't know if the problem is the firmware or the hardware itself.

I wanted do make a ROM dump of my version because it seems the most recent, that way I could flash other ROM's to see if solves that problem and that way it may be helpful to others with same or similar tablets.

My only problem is how to do that ROM dump and how to put it in .FW format to be used with SDCARD.

Can anyone point me to that path?

Hi releaser,

First of all, I have finally found working ADB USB drivers for my Polaroid MIDR477 tablet (same as GS710B) : https://www.dropbox.com/s/atft0999rm8xehw/usb-driver-funtek.zip

Had to add my vendor ID into adb_usb file in Users/<username>/.android/ folder (0x10d6 in my case)

I am trying to dump my rom as well. I tried using romdump v82 but at the last step I get "not executable magic 7F45"

Here are the steps I have used :

Could you provide me informations about your kernel version etc ?

Let me know if it works for you. I suspect it is not working because romdump may not be compiled for MIPS architecture. I am trying to find manual methods because I would like to create custom roms for this tablet. I have already tweaked some kernel parameters + alternative laucnher - it is much faster than the original rom. :p

UPDATE : seems like I've found the command in order to convert those FW files into IMG and vice versa. It can be done under Ubuntu :

UPDATE 2 : Good news. Found out that some ATM7013 tablets were using Android 4.0.4 not sure if you have that version of android.
