Hi,

First i want to tell you my english is too bad .. but i will do my best..

This is the first Thread for this Phone..

_____________________________________________________________________________

A- Unbrick Acer Liquid Z330 (On Windows Only)

Step 1: Required Files ->
1- Converter (To make a System.img file) : Download

2- Stock Firmware :
For "WW_GEN1" : WW_GEN1

For "EMEA_BGCS" : EMEA_BGCS

(If links not working download from this link Acer Official)

3- Download & install Adb and Fastboot from this thread : ADB and Fastboot

4- Download & install Python 3.x (Required for Converter) : Python For Windows

Step 2: Prepare Files ->
1- Extract Converter folder.
2- Extract Stock firmware and copy "file_contexts" , "system.new.dat", "system.patch.dat", "system.transfer.list" from it to Converter Folder.
3- Launch "Converter.exe" and tap any key and wait...
4- If all done you got 2 file called : system_new.img and system.raw.img - we need just one file called system_new.img
5- Move "system_new.img" from Converter folder to your adb folder (for me is C:\\adb) and rename it to "system.img"
6- Back to Stock Firmware Folder and copy from it this files "boot.img", "misc.bin", "NON-HLOS.bin", "rpm.mbn", "sbl1.mbn" to your adb folder.
7- Check if you have on your adb folder all this files: "system.img", "boot.img", "misc.bin", "NON-HLOS.bin", "rpm.mbn", "sbl1.mbn"

Step 3: Enter to fastboot ->

2- Press Volume Up (Volume +) don't release it and press power key untill Acer logo appear and release power key only (keep your finger on volume up) until you enter to recovery mode
3.a- if you have stock recovery, just choose Fastboot mode
3.b- if you have TWRP choose Reboot and Bootloader
4- Connect the device to the computer through USB.
5- Now launch CMD on adb folder (press shift on keyboard and right click on your adb folder and choose "Open Command Window Here".
6- Verify your PC sees the device by typing :

fastboot devices

***** If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine. *****

Step 4: Flash files ->
1- Execute this commands :

fastboot -w

fastboot erase cache

fastboot erase sbl1

fastboot flash sbl1 sbl1.mbn

fastboot erase rpm

fastboot erase misc

******** NOTE : flash system take about 5/10 mins.. Don't worry about "Max length message" just wait until you show you "Finished" *************

fastboot erase boot

fastboot flash boot boot.img

fastboot reboot

2- Normally after finished the phone take about 10mins on boot to system.. just wait

3-[JUST IN CASE] If your phone stuck on demo mode (show demo mode on bottom) please don't worry.. connect it to wifi and reboot.. Phone check the updates.. download and install all update and do a factory reset.

Sorry for my bad English...

I'm here if you have any questions..

 

[Mounir9912]

the converting the system.new.dat files to system.img part failed (the program gave some error). Could you maybe provide the system.img you used?
Also, did your phone keep going off and on again during those 10 mins of first startup?

System.img is a big file to upload about 2.6gb ... your are install Python or not ?

My phone stuck on startup around 15 mins .. but it's working..

Please try both official rom.. for me my phone working only with the second one..

I've tried it with the other rom and it worked. Well, actually the converter didn't work. I actually had to use this:
https://github.com/xpirt/sdat2img
to create the system.img in ext4 format, then I had to use this:
http://forum.xda-developers.com/showthread.php?t=2749797
to create a flashable sparse chunk from the system.img.
the rest of the stuff like the boot, modem, cache etc flashed just fine. After flashing everything it booted perfectly.
Only problem is it's in demo mode and it requires the google account of the previous owner to log in before it unlocks. Since I'm only repairing it for someone I don't have that and can't get it out of demo mode for now.

When I try to update the phone, it automatically boots into twrp recovery and after rebooting it says update failed. I think it's trying to update via the recovery but it can't because it isn't the original recovery. Do you have the stock (original) recovery?

Btw, where did you get the EMEA_BGCS firmware from?

After flashing all files the phone back to stock recovery itself.. please use erase commands..

[Mounir9912]

I did do all the erase commands, did you also erase the recovery though?

 

[Mounir9912]

When you have the time, could you explain step by step what you did to convert the .dat files into the .img files? That's the only thing I did differently because it didn't work for me (yes python was installed)

 

[sYntrax121]

Where give you this problem ?

everytime I run "fastboot erase cache" command

 

[Ysfzone]

everytime I run "fastboot erase cache" command

Just ignore it and jump to next command

No unfornately I have' nt an other program to do that, but I have tried to install the original rom of acer and I have this message :
E: footer is wrong
E:signature verification failed
Installation aborted

I tchat with a technician of acer. He ask me to give the build number.... Yes but I can't give it that. My mobile is bricked! He advises to send my phone on SAV, but the phone is rooted!

Is there someone would be kind enough to give me the build number, please? :crying:
Or is it possible to get this number with adb?
Thank you for your answer and sorry for my English

На 4pda .ru есть тема "Обсуждение Acer Liquid Z330 Duo" страница 47, пост #930 в ней описан способ прошивки и сама прошивка 027 версии для разных языков. Телефон прошивается без проблем, проверено. Ссылку сайт не дает вставить. По этому ищите вручную.

Amazing work!

Windows 10 mobile --> android = Problems

Hello. I installed on the Z330 Windows 10 mobile. Help please go back to Android. Presumably change Disk Partitions. How is it to create one?

 

[Last Roze]

TWRP won't Install, it's always goes to stock Recovery instead TWRP. Help please thanks ~

 

[ludwiglintw]

I got the same result with #19, and my image version is Acer_AV0L0_T01_RV01RB10_TWN_GEN1.
The fastboot flash command seemed to pass, but I can not boot into TWRP. It still stayed in the old recovery mode.
