Hi All,
So, I tried to flash Cyanogen mod last night using the instructions here: http://wiki.cyanogenmod.com/wiki/Samsung_Vibrant:_Full_Update_Guide. I was coming from a BIONIX ROM that flashed fine.
Anyways, the phone went into a reboot loop in the recovery screen and I foolishly just held the power button until it stopped. When I turned it back on it was broken. That is, now all it does is display the white Vibrant logo in the middle of the screen with the smaller Samsung logo below it. If I hold the power button for about 8 seconds the screen goes black for about 2 seconds and then comes right back up to where it was. I can't seem to even turn the phone off any more. It just stays on that screen permanently unless I hold the power button, in which case the screen is off for 2 out of every 10 seconds. Yanking the battery of course turns it off, but putting it back in immediately returns it to the state I've described.
I've scoured these forums and tried every button press + battery state + cable state + SD card/SIM state combo suggested, but the phone won't go to download or recovery mode. I found one thread describing the exact same problem. The OP said he'd try a jig and then disappeared without any further updates. I'm going to try to get my friend to make a jig using one of these sets of instructions
http://forum.xda-developers.com/showthread.php?t=819551
http://factoidz.com/how-to-unbrick-your-samsung-vibrant-galaxy-s/
but until then my questions is: does anyone have any experience with this problem (can't even turn the phone off)? If so, do you have any recommendations? Did a Jig work?
keep trying to get to download mode, pull battery, plug usb in to computer and to the phone, while holding both volume up and volume down pop in the battery. People have tried hundreds of times with it not working and then all of a sudden *bam* download mode.
So... my friend made me a jig and it works in that I can see the shoveling droid indicating download mode. However Heimdall/Odin won't recognize my phone. Heimdall's zadig utility won't locate the phone either, even with the cable plugged in. I'm, once again, stumped.
Just an update; I've tried Odin on three different computers, two Windows 7 (64 bit) and a Mac (with Heimdall). None of them seem to recognize the phone. Device manager on the Windows 7 machine does not update when I plug the phone in (in Download mode via the jig or not) and I can't find anything about Samsung in it anywhere. However I have installed the Samsung drivers; a few different sets I've found around the forums. I've also tried a couple utilities like the Vibrant toolbox and one click unbrick. Nothing seems to have any effect. I was so hopeful when the jig worked and got me to download mode, but now it's seeming I'm actually bricked. Has anyone seen a phone that could get to download mode but still be bricked? Oh, and I checked the cable using a friend's phone; her Mac recognized her phone using the cable. Haven't tried her phone on my Window's machines though.
Once again, any help is more than appreciated.
Have you tried to see if adb is working? If it does then try adb reboot recovery? If it works there is a file I can post for you later (is in my pc) that can restore your sbl.bin and fix your download mode problems.
Thanks for your help everyone, the problem was apparently resolved by a new cable; which is strange because the old one works for data transfers... just not for flashing apaprently. :S
GS701B [ATM7013 CPU] Brick Repair
In this thread i am going to show you how to unbrick your gs7013b tablet without recovery mode.
Please be aware that i have spent a lot of time researching and sourcing the resources to be able to do this and it may or may not work for other MIPS tablets....
firstly you need to set up your computer environment (drivers etc)
Downloads
Actions Product Tool 1.02_02 (Developer Edition)
Firmware Files
When you have finished download the above files extract the actions developer tool to a folder on your desktop for easy access and do the same for the firmware files.
Now we need to get your tablet into ADFU Mode (ADFU = Actions Device Flash Utility)
FOLLOW THE INSTRUCTIONS CAREFULLY OR YOU WILL HAVE NICE LOOKING SQUARE FRIZBY
firstly open up your tablet by popping off the rear panel.
when you have opened the tablet up you should have something like the below picture.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now to get the tablet into ADFU Mode connect your usb cable to tablet and computer and remove any memory card you may have inserted.
now you need to find a tiny flat screwdriver or knife or something similar and we need to short pins 7-8 or 8-9 on the tablets nand chip to force it into ADFU Mode while shorting these pins keep pressing power button until computer recognizes it.
see picture below.
NOTE: i have been informed by some users that the nand chip on their devices is actually soldered on inverted to find pin 1 simply look at the chip and in one corner there will be a little circle which is sort of sunk into the chip this means that pin 1 is on the same corner as the little circle..
when you get the tablet into ADFU Mode your computer will make a sound as if you have just plugged in a usb device. Your computer will now ask for the adfu usb driver which you should have in the Actions Tablet Product Tool 1.02_02(Developer Edition)\Tablet Product Tool(Developer Edition) 1.02\Driver\ folder on the desktop which you downloaded earlier. point windows to he driver and you should now have the device installed...
now goto the Actions Tablet Product Tool 1.02_02(Developer Edition)\Tablet Product Tool(Developer Edition) 1.02\Product folder and run the mainapp.exe
the tool will open and then ask for a firmware file choose the icecream_gl5201_q8_rgb.fw which was in the firmware files zip you downloaded earlier
Now when the tool has read it you need to click the button as in the picture below.
Now on the right of the tool there are a few check boxes etc LEAVE EVERYTHING ALONE apart from the 2 options i explain below
click the image button for FAT_MISC Partition and choose the ACTA.IMG you downloaded earlier in the firmware files.zip
no click the image button for System Partition and choose the ACTB.IMG you downloaded earlier in the firmware files.zip
Now click the big green button as in picture below.
when flashing is done reboot tablet if it doesnt reboot automatically
BOOM working tablet... you should now be able to use your tablet with what you just flashed or you can try a different rom using stock recovery
CREDITS
massive thanks to
Edo2013 (xda forums) for helping me with software and firmware sourcing and flashing.
EDIT: IF YOUR TABLET WILL NO LONGER GO INTO ADFU MODE AFTER BAD FLASH AND SEEMS TO BE TOTALLY DEAD USE THIS METHOD TO GET IT WORKING AGAIN

hi at which point in the above process do you get the errors?? i cant help you without a bit more information.. if the errors are during flashing then please try a different usb cable and make sure your in adfu mode by checking device manager.. also if you are using windows vista/7/8 it would be a good idea to run everything as administrator or turn uac off completely. make sure your computer is setup correctly and fully updated with the latest .net framework etc...
Q8 GS701B [ATM7013 CPU] hang on android logo
Very helpfull tutorial. Thank you.
But I've got a little bit different problem with my tablet. When I turning on my tablet during booting it is hang on android logo. I've tried all firmware from ele-china and tried also icecream_gl5201_q8_rgb.fw and CEMA10S24 but no one works for me.
When I use your method upgrade is successfull but it is still the same problem with hang on android logo.
I've tried also check box FLASH READ CHECK see attached screen shot. After that its appear checksum error and error 81.
Do you have any idea what can help wit this issue?
My gs701b tablet is not bricked but its touch screen does not work. I tried to download iccream rom you put here to my tablet and I tried another
Rom but touch screen does not work? Is that hardware problem or software. The problem occurred after upgrading to rom upgrade.fast.fw.
Thanks
you will have a hard time getting it to work what you need to try to do is pull the ts drivers from your previous working firmware and then insmod them to this one although doing this is not an easy process it took me week to get my tablet working again.. your ts dont work becuase it uses a different driver for touchscreen which is not the same as mine you need to find someone with the same tablet as yours and get them to give you a dump of there acta and actb partitions....
i currently cant give much support as i got rid of my gs701b tablets as it is a mips tablet and the support for mips is almost non existant becuse of its incompatibilty with almost all apps on the market and the lack of firmware for these tabs are almost also non existant..
I have flashed some wrong firmware that was supposed to be for tablet with a home button. Now it does not power on. Screen does not light up. When I plug it in with usb cable I hear windows notification sound. Then I longpress power button and I hear windows notification sound that indicates shutting off connected device. Doing so also makes it to disappear from device manager. As soon as I release the power button I hear a positive notification sound again and it reappears in device manager once more. So I am stuck at this point. I managed to install unsigned Actions USB 2.0 HS driver, this is how it appears on device manager. I have tried to power it on with cable connected while shorting nand pins but same thing happens.
* UPDATE * So I tried Again. Screen lighted up and is white. I opened tablet product tools. Added firmware and two images. Pressed the green large button. Process have started and got stuck at DOWNLOADING ADFUS ... 20% clock is ticking at 19 minutes now and the progress bar wont move.
* UPDATE * After 143 min and 30 secs i checked on the progress of downloading adfus. It was still 20% but I noticed that a small question window popped up "upgrade firmware" pressed OK. Progress bar went to 95% with title UNKNOWN ERROR. The clock has stopped.
* UPDATE * I have tried again. It takes about 60 minutes until I get the UNKNOWN ERROR an the flashing process stops. Maybe Im not getting into adfu mode? The tool program thing the tablet is ready for flashing as soon as I plug in usb cable or hold power button for 10 secs to shut it off and then release it. The screen goes white after download adfus reaches 20% and it takes about 5 seconds.
* UPDATE * Now I understand that small pop up window on tools program actually says "upload partition error".

i have never had this problem all i can suggest is trying to use a different usb cable or maybe even a different computer... i had something simular to this before a while ago an i took it to friends house and used his laptop and it went through the process perfectly..
Would like to say thanks handy trick work wonders, Aoson M723, (Actions ATM7029) was looking at upgrading, flashed incorrectly. Only issue now OTG is still not working and Gsensor is not working now
Just happy to have the tablet working again.
One minor issue, when I plug in the USB, the tablet shows the boot up image, little odd, what could the possible cause be for that ? I can only think of the actions USB driver causing the trouble how do I go about removing the driver ?
Dear sir, any chance that you have tried this one an Ainol Novo 7 Venus Lite. Mine is deep bricked and I can't even get it to be recognized on my Laptop, by holding Vol+ and Power. I got CXZ ADB drivers installed and the Pad tool Ver. 1.05, but nothing happens and I fear I need to open it up and shorten pin 5 and 6 as mentioned by fuser-invent here;

Can you help me out here?

message: "Encryption unsuccessful"
Hi!
Everything went perfect with update with no errors. But after the android logo, when system is starting, I see message: "Encryption unsuccessful" and than folowing text: "Encryption was interrupted and can't complete. As a result, the data on your tablet is no longer accessible. To resume using your tablet, you must perform a factory reset. When you set up your tablet after the reset, you'll have an opportunity to restore any data that was backed up to your Google Account". There is a button "Reset tablet". After the reset, tablet starts I reach again the message above.
Any ideas what's going wrong? After update tablet did not starts alone, but I manualy press power button and it starts. Before power on, I see that update proces in MainApp.exe was finished.
And also I have no recovery options by pressing Volume UP + Power buttons.
And finaly: can I put other firmware to upload using that application, and should I use acta.img and actb.img whith any other firmware?
Thanks in advance!

I have been working on this tab for days, and I have the exact problem as this dude mentioned. I can't get into ADFU when I short the pins anymore, and i've been trying for over an hour, which means I can't flash again. No recovery options, no way to access USB debugging on the tablet, I can't figure this thing out. I think the cause might be manually restarting the device once it appears to be done but it really is not. Perhaps our impatience got the best of us.
Trio Stealth Lite 4.3 GS701b without home button. Please, please help us. Willing to donate a handsome amount, and i'm completely serious.

hi sorry for my ignorance i have been away on holiday...
the picture in the OP of the nand chip is a little misguiding.. i am guessing you have both tried pins 7-8 and 8-9 if so an its not working try the pins on the other side of the nand chip as some model version differ from others i have had 3 of these and had the same issue although i solved the problem by getting a thin sharp blade eg, craft knife blade and i pressed it onto all the pins on one side of the chip and this worked for me although be aware of the fact that you could possibly permanantly damage the nand by doing this... (but i have not ever damaged a nand chip or tablet doing this and this is now my preferred method..
Also try pins 5 - 6
and when shorting the pins also try to push the vol- or vol+ and the power button
there is no other way to get the tablet into adfu mode the only way is by shorting the nad and while you have the pins shorted turn the tablet on..
if you have any questions or need more info let me know..

That was genius because it worked. I just pressed a cream cheese knife against the opposite side and it booted into ADFU mode, first try. Thank you. here's some images, maybe you can include this in OP for future reference if the same thing happens, because after the flash it switches which pins need to be pressed.
Problem is, though, that I still get the "encryption unsuccessful" message after a successful flash. I can't access USB debugging, a factory reset doesn't get rid of the message, and I can't seem to find the recovery menu to flash a different ROM. Perhaps you know how to get into recovery/download mode? Or is that ADFU and I should find a different ROM to flash with that program? Here's a video if you want to see exactly what's happening. (It has my beautiful voice, lol.)
Thanks again.
At my tablet the flasher is getting stucked at 20% .
Is there any solution ?
Thanks !
Glad it worked for you..
as for the encryption problem i personally have never come across this and i would defo suggest trying a different firmware or maybe even a different version of the flash tool..
getting stuck at 20% is because you are trying to flash incompatible firmware..
Thanks for the reply but where to download correct flash for my tablet ?
ATM7013 , GS701b without home button .
Thanks !

Good question... The answer we all would like to Know but you will find some here these are all that i know of at the moment
http://www.ele-china.com/soft/tablet/Atm/Q8/
let me know how it goes..
an if the link above contains what you need please dont forget to hit the thanks button
My tablet is bricked . I cannot enter recovery menu and flash from sd-card .
That firmware aren't recognized by the flasher .
How the problem occurred
So a year or two ago I bought a Jiayu G4A/T/Whatever they're calling it and safely got it here. I've used the stock ROM for a bit but I wanted to get rid of the bloatware that was still on it, so I eventually ended up with a properly rooted phone with a ROM from Jiayu.es (Everything worked, have ClockworkMod as recovery, accessible via Mobileuncle Tools), which was essentially a stock Kitkat rom made to work for the phone. Now I got sick of the ROM and recently saw the new EMUI version on Huawei's P8 Lite, so I figured I'd look around for a tailored ROM running that, and ended up at "jiayu-emui-3-0-stable" from Needrom.
What I did
1. I downloaded a ROM from Needrom with identifier "jiayu-emui-3-0-stable" (I can't post external links)
2. Backed up my important files following a guide from androidcentral titled "[Guide] How to Backup and Restore Apps and Data when installing new ROMs" that I can't link,and did a full backup using CWM
3. Placed the ZIP on my internal SD card, went into recovery, wiped data/cache (not dalvik, since it wasn't described in the instructions, I think this might be a probable cause) and installed the new ROM from ZIP
4. Rebooted the phone and now it's stuck in the boot loop I mentioned.
What the problem is
Bootloops aren't that much of a problem usually, except this one is... I can't get into recovery mode. From there on it'd be cake, since I made the right preparations, but I can't get into it. While connected to my PC it keeps powering on, showing a splash screen from Jiayu.es briefly (which shouldn't be present anymore) and powering off after 10 seconds, only to come back to the splash screen.
What I've tried
I've unplugged it, removed the battery, waited to get a full power cycle and tried to hold my buttons in these combinations: [power button + volume up], [power button + volume down] - but neither work. It just keeps going with the boot loop. I can succesfully power it down, and when I plug it in from there it shows the low battery image. At the moment of seeing that I thought I could connect to it using ADB / Fastboot, but no luck there either. It keeps saying no devices found, and with fastboot it keeps on <waiting for device>.
My questions
What exactly can I do if there is no way for me to get into recovery mode? Are there any alternatives? How can I get my device to be recognized by ADB? Is that even possible? Why is this bootloop any different from others?
Update from the massive Q&A thread:
ZipAddict said:
Is it booting up on its own too after being off? This happened to wifes phone and it turned out the power button was stuck. I took a pencil and hit the power button with the eraser a few times and it worked then. Her case mustve dislogded it. I will keep my fingers crossed for u. If not send me a private message and i will look for an answer tomorrow and get back with u

Thank you for the reply!
Yes, it does. I took the battery out and let it lay disassembled for a night, after which I cleaned it a little and re-inserted the battery. With the case back on, nothing happened, so the power button wasn't stuck for sure. When I powered it back on with the power button (no USB attached) it showed the emblem for ~8 seconds and powered off. It then buzzes to show it's powered on again and up comes the splash screen again. Could it be that the ROM was just a rebooting falsehood? Why would it disallow me getting into recovery mode? I really hope there is something that can still force the device into recovery mode / interact with it somehow while in this state.
Oh, I also tried to see if the volume down button was broken but all the contacts seem intact, plus, they worked an hour before I started switching roms.
So i was using RessurectionRemix (a version from last month) and recovery twrp 3.1.0-0 and the phone was working great!
Yesterday i left my phone charging over night and in the morning i wake up to my phone bootlooping!
So i tried different things including everything it says here https://forum.xda-developers.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949 without luck
I can get it into recovery and fastboot but as soon as i let the key combination go the phone stops and just shows a black screen (screen is on) and i cant get into qualcomm recovery to flash!
And the only way to shut off the phone is by holding power + vol up + vol down!
Any solution or suggestions?

connect phone to computer, try force shutdown phone by hard button, ater phone shutdown, immediately release power but keep both volume. Phone maybe will enter Qualcomm flash dead mode, and Flashone will regconize com phone (refresh nedded)
Hope you success ! And believe, if a phone can flash with Qfil or Flashone, almost that phone never die (software)
Are you able to connect to the phone via Vysor, either via Chrome browser or as a standalone app on Windows PC when you do not see anything on the phone screen? Please post if Vysor install goes thru successfully. Hope your developer options/USB debugging are on. I assume your phone boots but may have display issues either hw or sw.

Phone gets recognized but not long enough to do anything (windows makes sound but doesn't install anything and doesn't show up in device manager)
try this guide
https://www.gizmochina.com/2016/11/20/leeco-x820-max-2-super-unbrick-guide/
You have mentioned that you are able to see the device in recovery and fastboot till you release the buttons - does this mean if the buttons are held say in fastboot mode you are able to see the device via "fastboot devices" or in recovery the twrp screen or nothing ever shows up at all? Are the buttons clicking properly? Check individually to make sure - particularly the power button. Does it vibrate at any point of time when you press and hold the power button? Are you able to see any backlight when you say the screen is on?
If there no backlight shine a torch or sunlight from the side of the screen to see anything at all on the screen.
Vysor reports apk not installed when it attempts to download from PC to phone but fails. With Vysor you will have two windows one showing status of phone - this is the main window. The other is the mirrored one - that of the phone when you click view on the main window. I forgot that the phone requires approval to install the apk. Please see the attached thumbnails. Keep touching the screen about 3 cms up from the bottom of the screen (not the phone) to see any change. Hope your touch works.
I know it is quite frustrating to try a number of things. I recently went thru the same on Galaxy S4 to make sure the phone but for the screen works OK prior to ordering the screen. Besides in my case developer options was disabled and touch also did not work. It took about a week of learning and trying to see something on Vysor. I never have used a Sam phone till that time this broken phone was handed over to me.
After a lot of trying i found out that when i keep pressed power + vol down or vol up while connected to pc and device is off it gets recognized as
qualcomm hs-usb qdloader 9008 long as i keep the keys pressed so i tried the flashone method but it just says could not connect
Are Qualcomm drivers loaded on your computer? I have not used flashone. I used QPST to see if phone is connected. I am not sure if they are same.

You have mentioned that you are able to see the device in recovery and fastboot till you release the buttons - does this mean if the buttons are held say in fastboot mode you are able to see the device via "fastboot devices" or in recovery the twrp screen or nothing ever shows up at all? Are the buttons clicking properly? Check individually to make sure - particularly the power button. Does it vibrate at any point of time when you press and hold the power button? Are you able to see any backlight when you say the screen is on?
If there no backlight shine a torch or sunlight from the side of the screen to see anything at all on the screen.
Vysor reports apk not installed when it attempts to download from PC to phone but fails. With Vysor you will have two windows one showing status of phone - this is the main window. The other is the mirrored one - that of the phone when you click view on the main window. I forgot that the phone requires approval to install the apk. Please see the attached thumbnails. Keep touching the screen about 3 cms up from the bottom of the screen (not the phone) to see any change. Hope your touch works.
I know it is quite frustrating to try a number of things. I recently went thru the same on Galaxy S4 to make sure the phone but for the screen works OK prior to ordering the screen. Besides in my case developer options was disabled and touch also did not work. It took about a week of learning and trying to see something on Vysor. I never have used a Sam phone till that time this broken phone was handed over to me.

It doesn't stay long enough in recovery or fastboot to do anything it shuts off after a few seconds even with the buttons pressed after that it just shows a black screen
Phone vibrates when i press power and shows leeco logo (not os logo) and after 1-2 seconds screen goes black and phone vibrates again and shows leeco logo again and just continues looping
if i try to press power + vol up normally it goes into recovery but as soon as recovery is loaded screen goes black (screen on just doesn't show anything) the same goes for fastboot if i press power + vol down it loads fastboot but after 1-2 seconds screen goes black
if i keep pressing keys the phone just stays longer in recovery/fastboot but only 4-5 seconds
I assume you have adb and fastboot. Since you say the screen remains on when booting to recovery open a command prompt at the directory where adb is and issue a command "adb devices" without quotes. Does it just exit without showing any device or throws up some error? Try this irrespective of the black screen.
Have you looked at and tried what is given by @HTC-TYTN2 at post #8? It is for Le Max 2 and you will find a link to Quallcomm drivers too. Do not bother that the link mentions X820 even your Max 2 is 821, 829, etc.
since it happened after charging, you might want to check your cable and battery. best is to get a cheap usb multimeter.

I too thought it could be the battery based on that's the screen goes off. But he also mentioned that the screen remains on but nothing to be seen after a short while. Wanted to suggest slow speed charging probably via a laptop usb as I'm not sure if he used high speed charging resulting in battery issue.
Did you solve the problem?
My phone just died completely! No response at all anymore. I'm contacting the seller now to send the phone back.
Looks like it is a hardware defect! A pretty odd one but nothing i can do anymore. I send it back and post what the problem is as soon as get any information.
Thanks to everyone who tried to help!

Try this:
https://www.androidfilehost.com/?w=files&flid=136823
download file, unzip, open folder, connect phone to USB via fastboot ( phone off phone + hold volume -) . Click to the flash app in your PC. The app should find the phone. Confirm TWRP problem -NO and start flash.
Drivers must be installed.

Hi guys,
this is the first time I'm having a trouble which has no working solution on the internet.
So, recently like month ago I bought mi 10 5g( 8 256 ), I've requested the bootloader unlock, and successfully unlocked it with MiTool for MacOS.
I installed the TWRP with the same MiTool and wanted to install xiaomi.eu ROM via ADB sideload. TWRP was on Chinese but i managed to see english pictures of TWRP and follow that to turn on ADB. I forgot to clear data so again I found tutorial with TWRP on english so I can see which of given button is for clearing data. I found it selected "data" swiped, there was two options on the bottom on Chinese and i assumed that the right one should be something like 'proceed'.
Click on that button gave me black screen. I tried to turn it ON with power key, long press power key, power key in combination with power DOWN and power UP, long press with volume keys. Neither of these worked for me.
I'm not getting even the buzz from the phone and when plugged in charger still no response from the phone, no lights, or screen wakeup.
My last option is to open it and remove the battery. Are there any other solutions that are not including removing the back part of the phone.
Thank you in advance
