Hello, does anyone know on what kind of memory unit the software is being held? I was wondering if it is possible to replace that unit, flash a rom into it and put it back and start the device, like replacing hdd in a pc? Reason: after failure with flashing stock, my tablet refuses to start or show any sign of life/response when connected to pc.
PS: I am 100 miles away from my tablet and won't be able to get it in a week so I can't disassemble it, sry in advance plus I couldn't find the answer on google.
Regards,
A
I don't think you can replace this device without damaging the tablet:

But maybe you can boot your tablet in USB recovery (APX) mode and flash the ROM that way.
Hi, I'm kinda of a noob at this stuff, but I've learned quite a bit recently from just reading around, so bear with me if I don't understand or need more specific instructions. I have the trio stealth pro 7 and it is always stuck on the boot screen with the android logo when I boot. I was attempting to flash cm9 on the tablet but after I wiped the tablet initially, i couldnt find the cm9 rom on my internal memory while in recovery mode, so I ended up turning off my tablet, which now doesn't boot up anymore (stuck with android logo).
I found a fix where you can use livesuite and adb to fix this issue; however, after installing adb, my tablet is not being detected, (my phone does). My tablet is not being recognized by windows in general, and it doesn't show up under device manager. There was one part of the step where I need to install usb drivers for the tablet; however, I cant find any online. I have used the tablet before with my computer before the attempt to flash cm9, so I am guessing drivers should already be installed. I feel I can get this issue fixed if I can just get adb to recognize my tablet.
Perhaps this fix is not the one I need and maybe there's a simpler fix. I'm just too dumb to have realized it. Another note to add is, pressing the combination of power and volume buttons does nothing. Please help!!! thank you!!
For starters: This tablet has absolutely no mods on it, it wasn't rooted, and the bootloader was stock, everything is stock. I don't have any backups of anything. It was purchased May 2012.
The story: Came home last week and saw an sd card on my desk, put it in my tablet, turned it on. Then I realised that the sd card I had just used was one that I previously had formatted with Homebrew channel for the Wii weeks earlier. Before I could take it out the damage had been done, the tablet was stuck on the acer screen. I left it running in hopes that it would work but after leaving it for 10+ hours on the acer screen I gave up. Turned it on the other day and now it's just a black screen. When plugged into the computer the tablet is running in APX mode. I have managed to retrieve my CPUID from a script in Ubuntu but I haven't managed to find an sbk converter.
So in my searching I hear a lot of mixed information, that the tablet can't be flashed from APX mode and some saying it can be. Some say it will only work if you have backups of your bootloader etc etc. I just can't figure out were to go from here.
I have used the reset button.
I have tried recovery pwr+down button.

There's a huge thread just for this, but here goes.
You can flash in apx mode, it may or may not save it, we've never tried, see below.
You can't use apx mode because we don't have the SBK to allow use of it, Acer kept it secret, so while an apx mode flash may save it, we can't do it. The info your stating is for the a500 which they cracked the SBK for. The a100 once bricked stays bricked until a motherboard replacement is done.

Really sorry about that, don't know how I missed it, I really have been looking around for information for a few weeks now.
Regardless I guess the only option is to scrap it, hack it, or pack it away.

Getting CPUID?
When plugged into the computer the tablet is running in APX mode. I have managed to retrieve my CPUID from a script in Ubuntu but I haven't managed to find an sbk converter.
Hey. I have an acer a500 and I am also stuck in APX mode but I do not have a CPUID. Would you be willing to explain how you where able to get it from APX mode, and would I able to do it from windows?

If your A500 was ever plugged into your PC there's supposed to be a way to get it that way. If not there is a method to get it from APX mode but the tool for it needs to be built and runs in linux. The first command, any command, thrown at the bootloader in APX mode will respond with the CPUID.
That doesn't help for the A100 as we can't get the SBK the same way the A500 does, but the A500 can still get the SBK from the CPUID. You'll have better luck in the A500 forums, though.

Ok. Thank-you very much! I was actually able to find it in an archive (I had written it down in the past, but couldn't find the file) Making lots of backups this time.
Hello everyone, I bought a brand new IPPO Q78 (Android 4.0.4) via focalprice.com 2 month ago. First day of using it, and by using I mean simply installing a few apps, and after reboot, I got BOOT LOOP problem, so it wasn't able to get to tablets home screen. After lot of reading about similar problems, I was able to successfully unbrick it using (I suggest others with same cheap china tablet that are also soft bricked to use this program, it really was the only one which helped me):
http://forum.gsmhosting.com/vbb/f781/android-tablet-wifi-cpu-a10-a13-wipe-rom-easy-zakir-gsm-1656461
Here is my situation now, you can view it:
http://www.youtube.com/watch?v=cU1KYIrvZWI
Before, when it was soft bricked, at least after this android logo came the android animation that looped forever, but my computer was able to recognize and install the drivers for Android ADB device, now it can't, it won't recognize my tablet no matter what, ONLY when I press volume up and connect it to usb port, then it recognizes and installs vid_1f3a_pid_efe8 driver, which also I cannot use with LiveSuite, why? I really don't know, I've tried every possible solution found on forums (mainly here, but elsewhere also).
Whole this situation is a result of me doing the CWM upgrade/install, I'm a newbie, so I cannot tell for sure what was it, I just know it was from xda--developers forum, more accurately this thread:
http://forum.xda-developers.com/showthread.php?t=2189640
after this, poof. I think it is hard bricked, and my question is, is there a way to flash it (btw, tablet is rooted) by only having access through mentioned driver vid_1f3a_pid_efe8 and without LiveSuit, cause I would have to download and try a 100 ROM's before I pin the one that suits my tablet. It's really a tough program to deal with, but if it's the only one, I would gladly format and reinstall my Windows OS as many times I need to to get it working.
Hello everyone! I'm new to the forums as a member, but used this for info since a few years back. Ok, so i've spent the past week trying to unbrick a samsung galaxy s2x (t989d on telus or koodo) and it seems alot of people are having trouble with this model. I've brought back another one identical to this one before, but it was only softbricked, so i could still enter download mode and use odin and just searched my butt off to find original roms and all and wound up bringing it back to life.
This one though... It's hard bricked with the dreaded QHSUSB_DLOAD mode. Found drivers for it to use it in windows, found QPST 2.7 build 422 and tried that to no avail since QPST always tells me the HEX files have a scrambling method which cannot be determined (even with it's own hex files that come with it, and tried on 2 different computers, one x86, one x64) so still stuck there. Tried ADB in windows but it never wanted to work in any way, also tried ADB with ubuntu linux but the devices list always ends up empty no matter how hard i try and what i change, even with other phones that are not bricked it won't list them at all... Also tried to use the SD card method and push an image on it to try and boot off the external SD using original rom from odin i have found, but have no idea exactly which image i need to push into the SD or if it need modification in any way to be able to boot like that, or if even the t989d does in fact truly support external SD card booting.
Before anyone says:" Ya you need to JTAG that, it's the only method..." First, no one around here has anything to jtag with and i don't want to cross the border to get it done, second this is the kind of job i need to get done without spending any money if at all possible cause phone is not mine and client on a restricted budget. Now i know this CAN be done as alot of people here and there were able to fix their phone that were on the same qualcomm series chipsets. I just need some help to do this on this phone, and any SERIOUS help would be apreciated.
I have access to original rom file for the particular MC4 version i have in hand, i have original rom file for another version of the 989d which i got to unbrick the first t989d a friend sent me, i have a NVbackup qcn file pulled out of my firends working t989d, and i also have a full backup made with TWRP on my friend's working phone. Wanted to pull out a better backup using darkspr1te's Brixfix-2-1 tool but like i said, in windows ADB wont work in any way even with python installed and all that, drivers also installed, but ADB isn't a recognised command. And in Ubuntu, no way to list any phone at all, even if i installed all the ADB files, JDK, did the whole rules file, changed attributes to the rules file, did the .ini file, and killed and restarded hdev and server... So i'm kind of at witts end right now, plus i've been sick and had a major headache for the past 2 days, and spent so far around 38 hours on this phone plus my normal job this week... So ANY help would be GREATLY apreciated, and i will gladly use this experience to help out the community and help put out a tool or whatever to unbrick all these damned t989d
Just le me know if you need any more info or files to help out and i will gladly do all i can to comply
Thank you in advance to this great community
Nobody?? not even a troll ?? pretty sure that not even a mouse is stirring
Update: I have finally been able to start to get somewhere with this. I was able to extract most of the MBN files needed for QPST from the stock rom, and created my own partition.mbn out of a PIT file i had from a previous t989d. And now i get the phone to accept download and don't get errors for those files, but it stays stuck when sending reset packets. So my guess is that either the partition.mbn file isn't good, or the mprg8660.hex file i used to substitute and test isn't 100% compatible with the MSM8260 chipset. I tried all i could but never was able to find the real mprg8260.hex file anywhere. So if anyone has mprg8260.hex and/or a working partition.mbn for the t989d, i would be grateful to get those so i can continue troubleshooting this and get it working. If you want any of the MBN files and everything i have so far, just send a PM or reply to this thread and i will gladly upload for you.
Don't use the 8660 hex, it might make it go out of DLOAD or SD mode and you'll get a HS-USB 9005 state instead of a HS-USB 9008 or a HS-USB 9006 state, and then you'll need to manually flash it while it reboots every 5 secs in factory recovery mode. Not fun stuff. Also, if you're playing in QPST, make sure you using 2.7.411 or later. And be careful. there is a 2.7.422 that is actually an old version with a Trojan floating around.. Also, be warned, If you don't know what your doing in QPST, you can make things a lot worse.

So far i had no problems using 8660hex, only stays on 9008 download mode so far, even after it's supposed to pop back to diag mode. And i AM using 2.7.422 but it doesn't seem to have a trojan or anything or else my anti-virus would've told me, but still kinda looks like an old version since most of the devices supported are the old ones and has nothing newer than 7XXX series on protocol modes in the settings menu. But like i said, so far i got it to respond with the 8660 and accept the mbn files, but still no change yet, still wont reset/reboot, still wont turn on or anything, just stays in download mode seen as a 9008. So i'll check to find 2.7.411 to try it out and see if does anything else. Even if it would reboot every 5 secs in factory recovery mode it would still be a step further than i am now right now it does nothing and stays in download mode. But thanx alot for the info!!
