Is This the correct section ?
I have a xda2 exec. I tried to update my rom, the congratulations screen displayed with a checking informaton on device message, this froze for some time so I disconnected the usb cable. when I tried to reset it, I get is a dispaly with just colours on it and it does nothing else, when I try to update again it shows an error connection error 101, also the device is not recognised. Is there a way to resolve this issue please and can someone be kind enought to direct me.
I used the rom update from - my-xda.com/xdaexec_soft2.html
Thank you in advance.

Try to hard reset your device
hold buttons: "-" + "-"
and then reset
so in practical terms, push the top 2 dash keys which are between your green and red phone icon buttons, and while holding them reset your device using the pen.
this should give you a white screen with a little menu.
You can now select clear device or something, I think it's the 0 or the X
it should work
if that doesn't work try to put your device in Bootloader
buttons: Backlight (front little button) + power button + reset button (with your pen)
again, hold the backlight and power button, then reset button
the screen should be dark, but if you look real close it would say USB or Serial v1.0 or v1.1 or something
you should be able to flash now using the tool
Also look around on this forum, loads of topics about upgrading/flashing and hanging problems

u might have to update bootloader, try 2 read wiki.xda-developers.com lots of usefulll infos for beginers

Thank you
To both members above, thank you for your time. I am now using the update tool, hopefully this will now work. I used the method pressing the light button and power and reset. (Bootloader)

Really don't know where to put.

First of all - I am a Sprint customer with the Latest Htc Rom -stock
List of problems and actions taken.
Problems
Soft reset reboots with phone in Airplane mode.
When the end key is pushed not long pressed but pushed it puts phone into Airplane mode.
Battery run time is not about half or even less than it was before.
Actions taken
Removed battery for about 10 minutes and tried a hard reset. Got to the screen where you are supposed to hit volumn up to restore to original and well the volumn up button gets pressed but nothing happens. So after waiting for about 15 minutes I do a soft reset to get back to the HTC Sense screen (today screen). I take the phone out of Airplane mode cause from reset. I hit the volumn up button and it works fine. I tap the end key and it puts me back in Airplane mode.
So I reflash stock rom back in that by the way wouldn't go until I unlocked the phone with HardSPL. Apon first reboot it still boots with phone shutting down into Airplane mode. Turn phone back on then turn power off. Take battery out. Replace battery. While holding Talk ad End buttons I tap power on for hard reset. Goes through try colored screen then to the volumn up option screen. I tap volumn up and nothing still happens.
I'm looking at Task 29 but I am worried about the volumn button not working.
Anyone have any ideas on what direction to take. Thank you

Which model is your device? You can find the model number above the barcode that is under your battery. It will be in the form of RHODxxx where "xxx" is a three digit number. From here, I'll be able to help you a bit better once I know which model you are using.

Thank you for the reply. The model# is M8RHOD400. Since my first post I have tried flashing other Roms and I think it was the Sharkie Rom that actually said it could find the end key file. Other than that all the other Roms I tried pretty much do the same. When end key is tapped it shut phone off. Plus the volumn up still doesn't work at the hard reset state. It works normal otherwise but when I try to hard reset it will not go past the first screen that says press vol. up to reset. Thanks again so far.

Ok, so the first thing we need to test for is hardware fault. To do this, you will need to perform a task29 and then flash the latest Sprint ROM. After that, try to see if you have the same problems. Please do not install anything while testing. If it works fine like this, then we will need to do some specific testing on the custom ROMs to narrow down the cause.

Things have changed a bit. Long morning. I tried flashing a few ROMs to see if any would fix it. I know a feeble attempt. Well one went bad and never got past the splash screen when it went to restart. Won't connect to ActiveSync. So I tried reflashing from SD card. and I get to
RHODIMG.nbh
OS -
Press Power button
to start update image
Press VolDn button
to cancel update image
The problem is I press power button and nothing happens. I press any buttons and nothing happens. I pulled the battery and reinstalled it and got the same again. I tried to run Task 29 but how. Won't load. Tried renaming rbh file but got the same results as above. I need a way to hard reset without buttons and its obvious that nothing working outside of windows. I'm lost.

First of all, you should stop trying to update with the SD card. That's the problem you're having, so we need to try something different. Flash it via USB. You don't need an Activesync connection. It just needs to change from SERIAL to USB at the bottom of the bootloader screen. Once that happens, simply run the RUU and it will flash to your device. Do task29 first. Then do the stock Sprint ROM. Task29 cannot be flashed via SD anyway. The NBH file in task29 is a filler file. It's the actual RUU in it that is modified to perform the wipe.
So, let's try this again.
1. Get into the bootloader by holding voldown while turning the device on.
2. Plug it in to a USB port on your PC.
3. Once the text at the bottom of the screen changes from SERIAL to USB, begin running the task29 RUU.
4. Once the progress bar gets to 99% on the task29 flash, hold the voldown button again and await the restart.
5. Once it restarts into the bootloader and the text changes again, begin flashing the latest Sprint ROM.
6. Allow the ROM to boot up all the way and settle down, then give it one soft reset.
7. When it comes back again, go ahead and test it out to see if your problems persist.
8. Report back here with the results, and we'll move on from this step.

Task 29 doesnt seem to working because it reboots back to the last rom. Everything is still there. I really don't think that any of the hardware buttons work outside of working in the OS and at startup. IE volumn works when unit is on or when putting unit into bootloader mode but Volumn button does not work when trying to do a hard reset or a Task 29. Power button turns on unit, turns off unit, puts into bootloader mode, starts hardreset. I have loaded a Custom Rom just because maybe with the X button on the bottom and bigger it might be easier. I'm all ears from here on out. Its seems I need to clear ROM or Cmos without button usage. I don't know if that makes any sense to you but like I said I'm all ears on what to do now. Thanks for the little lesson on flashing without Activesync. Feeling kinda stupid about that one. Thanks for the help so far.

I don't know where you got your task29 utility from, but you cannot run it from SD. It HAS to be used with the RUU that came with it. It is the modified RUU that runs the task29 function. Just to eliminate the confusion, I'm uploading a modified RUU to this post that is very simple to use. Extract it from the archive and follow these instructions.
1. Connect the device (in bootloader) to your PC and wait for USB to show in the bootloader.
2. Run the RhodiumWAdvancedRUU.exe
3. Select the third radio button that says "Perform task29 only."
4. Uncheck the box that says "Restart utility when task29 completed."
5. Hit Next and keep going through it until it flashes.
6. Once the progress bar gets to 99%, hold your voldown button and wait for the reboot.
7. Once you are back into the bootloader, wait for USB to show up on the screen again and then flash the stock ROM.
8. Once the flash is complete, allow it to boot once and settle, then soft reset.
9. Once it restarts, test the problems again.
10. If the problems persist, we can move on from here.
Note: If you want to make sure that the task29 utility worked, feel free to try and boot it after performing the task29 and see how far it gets. If it gets stuck at the bootscreen, then you know it worked. Simply pull the battery, or hit the reset button, and power it back on while holding voldown to return to the bootloader and continue with step 7.

I cannot find the uploaded file that you sent, but also I am not trying to run the Task 29 file from SD card. I'm trying from the comp but like I said, when in any mode other than Windows, I really believe none of the buttons work. Volumn down at 99%. Volumn up on a hardreset. The buttons work to get me into the various mode either from Windows or at startup, but once into the special modes I think I don't get any buttons. That and the fact that the only thing the endkey button does in turn phone on and off but doesnt end anything is peculiar to a person like me. Anyways I didn't get your Task 29 file yet.
Thanks again

That's because I forgot to upload it. Sorry. here it is.
I know you feel that way, but there are a few things we can try. We just need to go step by step to rule things out. Please trust me on this. I'm trying to keep from saying that your phone is having hardware troubles, because I think it is fixable as it is now. We just have a certain order to attack it from.

I do appreciate the help I have always gotten from this site and thank you. The worries that I have are actually getting any buttons to work when doing any work on the phone outside of the windows format. I noticed that at 99% I am to tap the vol. dw button and I don't think thats gonna work. From my desktop computer exsperience that I have I know there is actually 3 modes happening that work in conjunction with one another. CMOS MSDOS and Windows. I don't think its a windows issure and I don't know what else there is in these phones that work, but I will try this program and thank you again. I will let you know where I at with it in a few.

Even if holding voldown doesn't work, you will still be able to boot back into the bootloader. task29 will clear the internal memory of everything. There won't be anything to load, so it will hang on the splash screen if it tries to load. Don't worry. We're going to try everything we can before we call it quits. This is a unique problem, but I think it can be fixed. Like I said, we just have to go in order.

Okay. First of all I'm sorry for the void between your last message and now. Its been a wild week so far. Thanks again for the help so far. With that said and done heres were I am at. I tried your Task 29 software and it did seem to be different at visualy. Possible problem is, is that when it rebooted after following your instructions, it did not go to the tri colored screen but to a blueish looking screen with the words Touch Pro 2 across the center. It almost looked like a splash screen, but never went any farther. So I'm not sure if that was acceptable or not as a proper task 29 but I did go ahead and load the stock rom into it and it went find. After the first reboot it started up with Airplane mode on. I shut it off and turned on the phone again. Everything was okay. You can only assign the phone button and nothing else that I know of so I couldn't see what was assigned to the end key so I pushed it. immediately it stuck the phone back into airplane mode again. Push or I should say tap and it took it out of it. I realize that by default the phone set the long press end key to shut the airplane mode on and off, but I am tapping and only tapping as I always have in the pass. Well so I got the idea of trying a different Rom in hopes that something will program the key to not shut the phone function off everytime I accidently tap the end key, I tried a few and Sharkies seems to surfice for the moment. By tapping the end key only brings up the Comm Manager instead of shutting the phone function down. Funny thing is though is that also was Sharkies default for long press. The problem has become with that now is that it has been just popping up by itself over and over. So I started tapping the end key when it popped up and suddenly it seems that it worked until I realized the the end key doesnt seem to be working at all. It clicks but thats it. So what to do now. Good thing at this time is the fact that I dont have to worry anymore about accidentally tapping the end key.Good chance it could be the button it self. I don't know. What ya think?

On task29, it removes the entire ROM from the device's internal memory. There was nothing to boot up, so it stopped at the splash screen. That's how task29 works.
Well, this allows us to completely remove the possibility of the software's effect on your problem. What is happening is that the device is recognizing a short press as a long press. Since the button commands are interpreted by the SPL, we've got one last thing to try before declaring hardware fault. We'll need to flash the stock SPL, again to see if that clears it up. To do this, I'd ask that you flash the latest stock ROM to your device. After this, you'll need to go back to the CDMA Hard SPL thread and grab the latest stock SPL. Flash that to your device. Then boot it up and see if the problems persist. If it continues to register short presses as long one, then you have a hardware fault. If this fixes it, then you should be able to flash Hard SPL again and load another ROM with no problem.

[Q] A100 bricked?

I am a newbie in this forum and would need some help to unbrick my tablet.
I have been using leaked ICS in the past 2 weeks or so. This morning when I started using the tablet, it was running VERY slowly. I rebooted it but it was stuck at Android screen for more than 30 mins. Running out of patient, I restarted it 1 more time and it can now only get to the Acer screen no matter how long i waited.
Tried a few things already with no success:
1. Hard reset using the pin hole bottom left - nothing changes
2. Go to recovery mode trying to use the HC rom (rename to update.zip) using volume up button. Once the green droid shows up for a few seconds, it turns into a droid lying down with a red exclamation mark. It will then restart itself after 30 seconds or so.
What's going on with my tablet? Any help would be appreciated.

Any help??

Cant use HC ROM...
As long as you are not BOOTLOADER UNLOCKED you can use a regular UPDATE.ZIP for your device... You cannot "DOWNGRADE" that is, you cannot go from ICS to HC again without some form of "hack" or "workaround"
See if your tablet allows you to re-flash the ICS build you were able to update to and post back... It may just be it corrupted some files...
Let us know... jejeje
UPDATE 1: And... Dont use VOL+, its supposed to be VOL-.

lol...vol+ if your like me and boot to recovery in portrait
Sent from my SGH-I897 using xda premium

I tried the vol - button (the one farther away from the orientation lock button), it seems like the tablet was not doing anything different at all. It will eventually get stuck at the Acer screen.
If i use the vol + button (the one closer to orientation lock button), it shows the text "Booting recovery kernel menu" in Acer splash screen. It will then go to green Droid screen with a spinning sphere. In less than 5 seconds, it seems to fail to boot into recovery menu with a 'dead' droid with a big red exclamation mark.
These are the update.zip file I found in the forum. They all gave me the same error:
Acer_AV041_A100_1.012.00_WW_GEN1.zip
Acer_AV041_A100_1.014.00_WW_GEN1.zip
Acer_A100_1.014.08_COM_GEN1.zip
Any more help? I can get upload a video to Youtube if it helps.

HOME Button?? Maybe??
When you get to the GREEN ANDROID... click on your HOME button and see if you get a bootloader/recovery type menu at the top left... If you dont get it from the GREEN ANDROID, try thesame (HOME button) while the RED DEAD ANDROID is showing...
When mine did that for a bit, I found there was a "hidden" recovery built in... Again, try to go to recovery and press the HOME button... You may have to press it for a few seconds...

Thanks for the pointer! It now shows a lot more information (while the sad Android with red exclamation mark is in the background)
I can scroll down/up using volume button for these options:
reboot system now
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
At the bottom of the screen, it is showing a whole bunch of yellow text:
E:Can't open /dev/block/mmcblk0p5
(No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/command
(repeat the above message for /cache/recovery/log, /cache/recovery/last_log, /cache/recovery/last_install
How can i select an option from this menu, btw?
I also tried to use the vol - button. I found that if i keep flipping orientation lock back and forth, it will show 2 messages at the top left corner showing "Erasing Userdata...Erasing cache..." in the Acer splash screen. Then it will freeze again....

PWR button to select
Make selection with Vol+/- and press PWR button to select... See if you can do a factory reset...
"
Or put the UPDATE.ZIP into your microSD and see if it lets you select the "Update from ZIP" message

Pressing the power button doesn't do anything. If i press it long enough, it just shuts down the tablet.

I dont know man... I cant get mine to there because I have the unlocked bootloader now... Have you tried either of the volume buttons... maybe the HOME KEY? that may be it...

I tried every single buttons on the device w/ no success. The home button only hide/unhide all the text. Vol +/- can scroll up/down in the menu. Pressing the power button doesn't work at all.
In the system recovery screen, it has the yellow text complaining about /dev/block/mmcblk0p5. Is there anything i can do with this?
It looks like I am running out of ideas to revive my lovely tablet. Is it time to throw it to a trash can?

Some people are trying to do it through APX mode but it can be difficult if you don't have certain info specific 2 your tablet...

no response? I guess this is a dead topic

same problem!
my A100 does not work and face the same problem now...
I could not select the item to even recovery or anything.....
Any one can help?

I called acer. We went through the hard reset thing. When he found out that it didnt work he told me to send it to them. So im packing it up tomorrow. Not sure if they are gonna try and fix it or just send me another one. We will see. Will keep u posted

I have been having the same problem. I can get into the system recovery menu from the dead android, but I don't know how to select menu items.
I've tried all the buttons on the device, but none work.

EXACTLY the same symptoms and exactly the same issue with not being able to select anything off the recovery menu.
Ugh.
Unfortunately mine is rooted so I assume if I send it in to Acer I will have to pay for the repair myself.

I had the same problem on my son's pad, tried every type of reset w/o any luck I finally got tired and called Best Buy they told me to bring it in and they tried the same resets before giving up and shipping it to Acer for repair. I just told them the screen froze after ICS update and 4 days later my son has his pad back in working order.

Px5 unknown boot screen? Error flashing

Good evening all
I’ve tried flashing my px5 8.0 to hal9k. I had read that first you must flash to 3.x to then Android 9. I put the boot card img on an 8gb card and put the unit into recovery. The flash worked and brought up the first screen. Then went to update from sd and now I’m left with the second screen. See pic.
Now i am unable to get back into recovery.
Any help would be great. Thanks
So I am unable to post outside links.
The first screen boots up black with navigation system upgrade card.
The second screen that comes up is black with red green and blue squares at the top with a load of Chinese writing it says at the very top in small writing - px5 v1.1

forgot to mention I have the unit that is unable to get into recovery by pressing the power / reset buttons. I believe it had mod installer app that put the unit into recovery.

Did you ever figure this out? Im having the same problem with my px5 head unit (same screen)

Help recovering a "bricked" MTCE, PX6 (Xtrons) unit

Hi all,
first post in this section, so be nice I have a very recent build Xtrons TQ700L unit that i have managed to soft(?) brick after rooting and removing a factory app ("Easy Connect"). On boot I get the initial logo, then after a long time a black screen that goes nowhere. I'm looking for advice on the best strategy to recover/rebuild it.
Hardware details...
build number:
rk3399-userdebug 10 QQ2A.200305.004.A1 eng.hct2.20200521.120545 test-keys
MCU version:
MTCE_GS_V3.53_3
As i understand it i have an "MTCE, GS" MCU and can ONLY flash MCU updates from the GS manufacturer. The MCU is probably not the problem here though.
I have a PX6, Android 10 build date of 20200521. Am I correct in saying i can flash any android 10 ROM designed for the PX6 that is newer than this date? Are the only differences between manufacturers cosmetic, like the nice launcher Xtrons supplies?
When i look on Yandex (https://yadi.sk/d/umCvHqCDzHccr), there is no PX6/Android 10 firmware at all from "GS", but there is from "HCT". Should i be looking at flashing the HCT/PX6/Android 10 firmware date 20200612 from the recovery menu? I can get to recovery easily enough by holding, then double clicking the reset button - i just dont know whether i should be flashing part of or the whole of the above package to fix my brick.
thanks.

So in case this helps anyone else, it was an easy fix. Baby steps below.
- grab the latest "Android 10", "PX6/RK3399" factory ROM either from threads here, or from Yandex. I found HA3_RK3399_10.0_ota(20200706).zip here on XDA.
- unzip the outer layer ZIP file and copy the inner "update.zip" to a micro SD card. The stock recovery systems dont allow any selection of ROM file names, so it must be update.zip.
- put the SD card in the "GPS" SD slot.
- with the unit on, reboot to recovery. My way was using a nail to hold the reset button in until the touch button lights began the flash, then quickly release and double click the reset again.
- in recovery, menu items can be scrolled through by either clicking the reset button, or (in my case) touching anywhere on the screen (easier).
- push and hold the rest button (or screen) to select the item.
- do a "wipe data/factory reset" (i guess) to be sure of cleaning out the old mess.
- then do "Apply update from SD card". it should automatically find the update.zip and apply it to all partitions.
- select reboot. Done.
The ROM i used was a "HA" branded generic ROM, so it didnt have the same launcher as my original "GS" (Xtrons) branded ROM. Xtrons wouldn't supply me with their stock ROM when i asked. The generic one was a little better anyway, since it has a stack of boot animations to choose from, whereas the Xtrons one only had the Xtrons logo. It also doesnt have the Easy Connect app, which is what I was trying to remove in the first place!
Additionally, i was able to obtain root easily by using the wifi ADB method here.

I did the same thing. Stupid app kept opening.
I don't have a micro sd card slot, hope it works with usb stick. Don't have one at the moment to try.
Same as yours.
Also, entering recovery mode you..
Hold reset button for 10 sec, release and immediately press it once.
I have a dicola px6 mtce
I'll update if i get it working.
