[Android Q&A, Help & Troubleshooting] smartmanvartan:
The touchscreen issue comes from flashing the recovery in the first post. Do not flash that recovery!. The one I posted works perfectly. The issue with the bootloop our friend has happened because he unlocked the bootloader and flashed the recovery in the same instance. You have to unlock the bootloader and reboot. At this point your phone will perform a factory reset using the stock recovery. Then you have to reboot into fastboot and flash the recovery. Once you have the twrp recovery, you can flash the root zip in the first post. But I say again, do not flash the recovery in the first post! Something happens when you boot that recovery and it somehow messes up the touchscreen. Read all of my posts, the same thing happened to me and I went and got another phone.. if you flash the recovery in the first post, restoring the stock recovery will not fix the problem.

I'm currently working on a non touch recovery that will back up all partitions in an effort to help anyone who has lost touchscreen from the other recovery in the first post.

Here is a video.

In the video, I said that I made the recovery, I misspoke, I ported it to our phone but did not compile it.
[Android Q&A, Help & Troubleshooting] :
Hi everyone

I have an Acer T07, and with the help of this tutorial and one or two other ones I was able to reach the step of unlocking bootloader (yay!).

However I messed up completely right after this. Unable to find TWRP known to work with my model I downloaded the one you posted (not in the OP), thinking the difference between T06 and T07 was certainly no big deal.

So I tried to boot this recovery (not flashing it, I'm a careful reader :P), but nothing happened, it just did boot my phone normally.

Then I was totally stupid and thought : oh this does not work when booting, well I'll flash it to see what it does. And on top of that I made another mistake : I did fastboot flash boot twrp.img instead of fastboot flash recovery twrp.img

So, well, got bootloop. Recovery does not work either.

I got my phone stock kernel from Acer website (unfortunately cannot post link because I have less than 10 posts) but what I got is obviously not an img file so I have no idea how to use it. Read the README, it tells me how to use Git to create ROMS.

I downloaded SP Flash Tools but the software is so unclear I have no clue how to use it - or even if it can help me.

Here I am. Any help welcome !

You're in a bit of a pickle... Your only hope if to find your stock firmware... I took a quick look and so far I haven't found anything... What's the FCC ID ending?
[Android Q&A, Help & Troubleshooting] :
I contacted Acer but they told me these images were not availible to the public (and I have to pay to send them the phone for repair !). I believe they are wrong : Android is open-source and I think they can't just put bloatware in it and call it theirs. Plus, in the phone's manual, it is said that for 3 years from now I can ask them for the full source code for free. I'm going to contact them and tell them this. Hopefully I can manage to get this firmware.

PS : What's an FCC ID ?
[Android Q&A, Help & Troubleshooting] smartmanvartan:
Acer likes to have two model numbers for their phones. Mine is the T06/Z525. The z525 is also the end of my fccid. It's written on the back of the phone where the model is written. It's easier to look for firmware when you can cross reference model numbers. If you had the build number, that would be the most helpful....
[Android Q&A, Help & Troubleshooting] :
Mine is a T07 aka Liquid Zest 4G. I can't find its zXXX number though...
[Android Q&A, Help & Troubleshooting] smartmanvartan:
Z528 from what I can tell. If it's the z628 I have the firmware but I don't think so. You never found the FCC ID?
[Android Q&A, Help & Troubleshooting] :
Yep that's it, z528. The z628 is the uppper moel, the Liquid Zest Plus. That's too bad !

I had Acer support on phone to try to make them give me the firmware files but the guy wouldn't let me have it. I was on phone for 15 minutes trying to get it but nope, gotta send the phone to them. They want me to pay 48â‚¬ for them to flash their boot.img on it - really, a 5 minutes operation.

That said maybe the z628 firmware will go on my z528. It'd be cool if you sent it to me so I can try, I have nothing to lose now xD
[Android Q&A, Help & Troubleshooting] smartmanvartan:
Don't do it...lol.. just wait a bit, I'll find you some firmware
[Android Q&A, Help & Troubleshooting] :
Wow, many thanks to you !
[Android Q&A, Help & Troubleshooting] smartmanvartan:
Found it. I'm gonna check it and reupload it for you and others.

THIS IS FOR THE LIQUID ZEST 4G/T07/Z528

Do you still have access to fastboot? try THIS.

So I have an Acer Z525 and the touchscreen isn't working... what should I do?
[Android Q&A, Help & Troubleshooting] smartmanvartan:
What about the recovery? Can you test the backup and restore function? And were you able to flash root?
[Android Q&A, Help & Troubleshooting] efrant:

The recovery seems to work fine (although I'm not familiar with TWRP, I used to use CWM) but I have not tested backup and restore for now - I'll tell you when I do. However SuperSU.zip returned error messages and did not enable root. :(

[Android Q&A, Help & Troubleshooting] smartmanvartan:
OK, I have a modified twrp recovery that backs up all the visible partitions. and i have a backup from my perfectly functional T06. I also have a set of commands that will let you restore the backup from your computer(because your touch doesn't work). So, first you gotta flash this recovery with fastboot. Then you boot into the recovery. plug the phone in to the computer if it is not done yet and extract the "t06touchfix3" folder from this rar to your phones internal storage. Now, open a command promt and navigate to your adb/fastboot folder. Type "adb shell". now type "twrp restore /sdcard/t06touchfix3" and let it perform the restore. After the restore has finished, type " reboot recovery" and once the recovery reboots, let me know if the touch functionality has returned. Good luck :)

But it wont reboot into recovery after applying the fix.

It reboots system instead, and hangs. About every 5 minutes it reboots.

It hangs for a few minutes and tries to reboot system.

Do you still have a firmware of acer z628 (t08)? If you have can you please upload it and send me a link? Or do you have a custom recovery for that model?
[Android Q&A, Help & Troubleshooting] DeNuNietNooitNiet:
I'm so sorry for this incredibly late response.

This was due to circumstances, so again: sorry.

I hope you still have those files and all, and willing to help...

I installed the stock firmware you linked to in post 64

Then I went to install the recovery. (After unlocking the bootloader once again.)

I rebooted the phone, and placed the folder called "touchfix4" on the root of the SD.

I applied the fix, using the same procedure I followed for touchfix3.

I did not notice any errors.

But when I rebooted once again, the fix didn' t work.

I tried to apply the fix once more, but I couldn't access any of the filesystems anymore.

So I checked the bootloader, which it was locked. I tried to unlock it but it gave an error.

C:\Users\mym4y4>fastboot devices
0123456789ABCDEF fastboot

C:\Users\mym4y4>fastboot oem unlock
...
(bootloader) Start unlock flow

FAILED (remote:
Unlock operation is not allowed
)
finished. total time: 171.652s

C:\Users\mym4y4>fastboot flashing get_unlock_ability
...
(bootloader) unlock_ability = 0
OKAY [ 0.015s]
finished. total time: 0.016s

C:\Users\mym4y4>

I tried several other things, but the bootloader remains locked.

When I boot the phone, I see a greenish desktop launcher.

I see the device in Windows Explorer but I cannot write anything to the internal SD.

What to do now?

EDIT:

I used this settings. That is what you meant, right?

EDIT2:

I am able to boot the device into system all the way to the homescreen.

I can boot into fastboot and recovery as well, but the recovery reverted to stock.

I all the file systems seem to be locked, so I cannot flash using ADB/Fastboot (nor transfer files through Windows)
[Android Q&A, Help & Troubleshooting] Wagh liddi:
The recovery in post #1 screwed up my touchscreen. I tried everything nothing helps.

I tried the solution provided by smartmanvartan, and the only response I got was a tiny vibration after hitting the back button. I also have the same errors as DeNuNietNooitNiet mentioned in post #64. I repeated it 6 times.

I am afraid the digitizer is broken. Otherwise I am willing to pay at least 10€ if someone has a solution!
[Android Q&A, Help & Troubleshooting] MasterSheea:
Wagh liddi, exactly the same problem here.

This recovery was worse than a virus.

I have tried everything and I have posted to ask help everywhere, but nobody is able to help.

I think that the files for the configuration of the touchscreen are in one of the partitions not present in the firmware's folder, I do not know exactly in which one.

The only hope to fix the phone is that someone would share a full backup, containing all the partitions. Or just a single dump file (made with the read back of SP flash tool) containing all the partitions: I can cut it from myself.

The Acer Customer Care service says that this partitions are not allowed for public use. To flash the partition we would have to send the phone to them.

This is a trick of the Acer to force customers to send the phone to them and to pay their rates.

All serious producers make available the firmware in their official webpage; Acer NO.

Of course Acer is not in good faith.

Of course, me too I would offer a coffee to someone able to fix the problem!

But never I will send the phone to Acer; they think to be too much smart, but at the end the result is that they behave not correctly.

About me, that was the last time that I bought an Acer device.

If you find a solution, please let me know; I will do the same with you.

Thank you in advance.

How to Backup Original Firmware?

Hi,

I am running Windows 10 64.

I tried to create a scatter file for the T0-6 Acer phone but could not!

You can back it up before messing around with other ROMs or recoveries that are not intended for our phone. But it has to be backed up from YOUR phone and restored to YOUR phone.
