unbricking alcatel idol X plus (6043D) - Alcatel Idol X Questions & Answers

Hallo friends, its great to find thread for noobs...
I am a bit desperate - can not find answer for my questions. I have alcatel idol x plus, which was bricked - originally not my so don`t know exactly what happenned but sudenly stucked in bootloop. The only think I can do is to get to recovery menu. The cache partition with rom does not exist, the sd card slot is not present. The problem is that only way how to load new rom to device is with adb sideload. The only stock rom I found was one, that is loaded by spl flast tool, which is unzipped one. And the only rom, that should be loaded by adb sideload shoud be zipped.
So my questions are:
1] IF I want to load rom using adb sideload, could i used that one rom which is ready for sp flas tool and load it file by file, or zipped, or I should not use this?
2] is it possible to use sp flash tool to upload new rom to bricked device or tha one which is just in recovery menu?
3] what is the difference betwen .ZIPped rom and that one which is divided to many files and uses scatter loading file?
thanks for advice and response in advance, sorrz for my English...

Noobie Question about ICS

I can't post in the development forums so I figured I would ask here:
I understand how to use adb and fastboot, etc.. What I am missing is with the new ICS ROM it states that I must "fastboot flash system system.img"; however none of the ICS zip file I have seen come with a system.img file (just the boot.img).
Am I missing something? Any help would be greatly appreciated..
I used the version available on Rootzwiki... not sure if thats the answer you wanted. I'm running 4.0.3 ICS on my wifi XOOM OC to 1.54. No FC's, reboots or anything of the sort. You'll need to be sure that you have su-install.zip, and other img files needed. As I said, you'll find them all on the rootzwiki website under xoom hope this helps, if not good luck.
You are talking about two different things here. I don't know where to start here you're all mixed up. There are several ways to flash a ROM, you can fastboot flash the .img files such as what you are referencing to. Or you can flash an update .zip file from recovery. The way you flash the ROM depends on the source, if its a bunch of *.img files you use fastboot, if it's a *.zip file you use recovery. Just follow the directions given for installation that are provided with the ROM you are downloading.

Hello, and welcome to XDA! =] Anyways on with your question. There are two ways to flash a ROM to your xoom. One being fastboot/adb, where you use the command line on your computer to send commands to your device and make it do stuff. This is where you use system.img, boot.img, recovery.img.
The second, is CWM (ClockWorkMod recovery) This, as far as im aware, is the most common way. This is where the .zip's come in. Because you take the .zip you put it on your external SD card. boot into recovery (after flashing CWM of course) and flash the rom. CWM is nice because you can also make a 100% snapshot of your internal memory state via making a nanodroid back up. That way if anything messes up you have a 100% backup you can restore at anytime if you need it.
In a nutshell, You use *.img files with fastboot and .zip files with CWM.
Anyways. If you're new to rooting. Please check out these two threads, They'll help you get started. =]

[Q] Rom Flashing w/ TWRP Problem!

Hello Im new to the world of Custom Recovery and Flashing Roms. So I'm having a bit of a problem!!!! I rooted my Sprint Galaxy s4 with odin on my iMac threw Parallels V Machine and windows. Worked great! i installed TWRP which also worked well. Ok heres my problem.... I boot into recovery and wipe all the things i need to and I've done my research for a rom that works with my phone I've also watched countless number of youtube videos on how to flash. i have the rom downloaded on my sd card. When i pull it up it lets me pick the rom but no swipe to flash. Instead... When i tap on the rom it goes into the files that the rom has in it and thats it... no way to flash it. Then I'm left with no choice but to restore my backed up stock rom. Does anyone have any ideas? What am i doing wrong if anything? Please help if possible. Thank you!
You are in the wrong forum. This is the Verizon variant.
But to answer your question it sounds like you extracted the zip file to a folder.
You do but extract it. You only flash the .zip file as a whole.

But i didn't extract anything i pulled it from my iMac is that the problem?
Does it have [Rom filename].zip? Or just show the rom filename?
The file list in twrp to install a rom will show filename extensions.

Moved to correct Q&A forum
There are 6 S4 forums...make sure you choose correctly
Also questions go in Q&A
Thanks
FNM
As was mentioned you've done something wrong; and that looks to be that you've extracted the ROM zip.
Since you downloaded it on a Mac it probably used the download manger and uzipped it.
You need to download the file (and keep it) so that it looks something like this:
Stock_Rooted_Deodexed_MF9_Rom.zip
or
Sacs_Custom_Rom_4.3_v3.1.zip
or
MetalROM_v3.3.zip
etc.
Copy that to you exernal SD card then in TWRP select install zip after you've followed the OP's instructions on wiping to select it and install.

Updating Asus Zenfone 3 Zoom ZE553KL by TWRP : some errors and difficulties

From the first time i was not able to upgrade my phone to another new version of Android.
The phone was bought on chinese store with Android version : WW V10.40.47.107 (Android MM)
When i checked availability of new versions, phone showed me no result available.
Then following instructions i unlocked bootloader and then install TWRP as recovery system.
I tried to install updates of ROM downloaded from Asus website using this methods with this results :
installing by TWRP with ROM transfered to internal memory of phone KO
installing by "ADB sideload" command KO
I partially resolved after many attempts updating only to Version V11.41.87.2 (Android MM)
I solved in this way :
i used TWRP installing from file transfered directly in microSD
i extracted from zipped file "updater-script" file that is possible to find in the following folder path :
META-INF > com > google > android
and then deleted this rows :
(!less_than_int(1494697617, getprop("ro.build.date.utc"))) || abort("Can't install this package (2017年 05月 14日 星期日 01:46:57 CST) over newer build (" + getprop("ro.build.date") + ").");
.....
getprop("ro.build.asus.sku") == "WW" || abort("Please use the right SKU for updating...");
.....
and then save file extracted and compress into zip file.
During TWRP install process i got some error updates, it seems connected to System folder/partition update
but at the end i was able to update Android to my phone
I tried to do the same method with an other update Version V20.32.67.25 i got a corrupted System folder/partition
It seems essential to update this phone to use original recovery system. Can anyone give it to me?
Or is there someone who has been able to install updates using TWRP without any error ?
Also after installation I wiped the Boot, System, Data, Cache partitions and then I restored from Nandroid backup done by TWRP.
But the phone did not start at the reboot.
I then had to reinstall the update with the method described above to get the working phone back
Why did Nandroid backup with TWRP not correctly restore the phone?
Many thanks to anyone can help me

There is a link to a rom in this post. In that zip you will find recovery.img. Flash it with adb, like you flashed twrp.
Then you can flash the last M official rom, and subsequently the first and last N roms.
That's the way I did it. I had to end up wiping data, to make it work correctly.
I'm also looking for a Nougat recovery.img.
I wouldn't like to go thru all the process again if there is another update.
Good luck.

i think you need flash full firmware bro ,
1. Download newer version firmware
2. You need Convert system.New.DAT to system.img
3. Move system.img and boot.img to minimal adb & fastboot folder
4. Open minimal adb & fastboot
5. Flash boot.img and system.img

Just to let you know I did this then downloaded each update from Asus website. You have to do it in order ie newest MM to oldest N to newest N. Takes a lot of time but it works. I now have N on my phone.
Thanks everyone for all your help.

After 11 hours trying out finally solved!!!
I originally just wanted to do a factory reset, and swiped then not only data/cache, but unfortunally - because of lack of expirience - also system partition. After that all the problems occured like described above and partitionally in https://forum.xda-developers.com/zenfone-3/help/unbricking-zenfone-3-ze552kl-dm-verity-t3563970 (there was no OS anymore, twrp warned me this every time I wanted to power off, but I couldn't install the firmware again through fastboot neither through twrp -> install zip; have got error 7 or 6).
Afer a lot of fears and hours of trying aroud possibilities above as well as ideas from articles here:

I have finally founded a solution!!! This is in FIRSTLY restoring original recovery and just then flashing the stock ROM. Here the steps to do for it:
a.) Download original stock rom (raw-version!) from https://cloud.mail.ru/public/HuMJ/wEybSNsQA (raw is to flash through AFT - asus flash tool) or from any other source you can find online; official name seems to be "WW-ZE553KL-20.31.49.2-MR2-user-20170620235128-release_raw.zip"
b.) Exctract and move recovery.img to your adb-folder on PC
c.) Boot your phone into fastboot/boot mode, connect to PC through USB-Cable
d.) Run cmd in adb folder, then type in the command "fastboot flash recovery recovery.img"
e.) Reboot and choose recovery mode - now you have no twrp anymore, but the original recovery menue
f.) Install update, which means, original stock from your sd-card.
Be happy!
It would be nice if you could give me feedback, whether my solution was helpful for you, because it took time to write it and hope it will usefull

But, I can't update android nougat any way. I convert system.new.dat to system.img...... And try to flash it but unfortunately that's not working......
Please help me .......:crying:
Yes, I did it with my Zenfone 3 Zoom (ze553kl). So, you have firstly to flash the original recovery - to find, as described, in the raw stock rom zip archive. Or, you can find all original recovery's also here: (not tested by myself) https://mega.nz/#F!p90wgAaY!l1JbJilmAUEKTKWu43pT9w
Copy recovery.img to adb-folder, then flash it in fastboot mode in the cmd with "fastboot flash recovery recovery.img". Also copy the original stock rom with Android N to your sd-card and put it into your phone.
Then reboot your phone into recovery - now you have no twrp anymore, but original recovery. Install now the zip with Android-N-stock-firmware from sd-card. Enjoy!

Boss ,
Thank you very much ...... Your solution absolutely excellent and work very well . I am very happy for your support . But unfortunately I found new problem on my phone ...... After update nougat a white line found on the display......
How can I solved it .......
Waiting for solution.......
Thanks again for your support ........
Glad to hear, that it worked for you as well. About white line I have no idea, but on other pages I have already seen somewhere, that other users also reported about this problem. Try to look at google "ze553kl update white line". You can also search a solution for ze552kl instead of ze553kl, because, as far as I know, the ze552kl (ZenFone 3, without "Zoom") is almost the same device, just with a little worse cam. Therefore, it seems to be longer on the market and to have more users, so there are also more solutions for problems which can occure to this device in the internet. Wish you a good luck!

Very helpful, thanks!
I must've messed something up when I flashed TWRP.
TWRP ran fine, but when I tried to start it up, it stayed stuck at the Android logo.
Then errors popped up when I tried to install the stock rom through TWRP.
I never would've thought or had the guts to restore stock recovery first.
This should get its own thread.
Edit: I think my mistake was unchecking "Mount system partition read-only."

After many days i finally found enough time to try to use your tips.
I tried to convert system.New.DAT to system.img but without success using this program Autotool 3.0
http://www.droidviews.com/convert-and-extract-system-img-and-system-new-dat-files-on-windows/
After this attempt i used a ROM provided by chinese store to flash its content :
system.img
boot.img
recovery.img
Original recovery.img is essential to install other updates.
After that i tried to install other updates recognized directly starting by phone but always without success.
So i have had to install updates using original recovery tool.
Now i got Android 7.1.1 last version installed on my phone but it's impossible to use
TWRP recovery tool.
Obviously it's possible to install TWRP instead of original recovery tool and also possible to make a nandroid backup
but it's impossible to use it to install original ROMs released from Asus and it's not possible
to use to restore nandroid backups.
Is it eventually possible to use a custom ROM ? If it's, which one and possibly compatible with TWRP ?
i solved issue of update, but TWRP ?

After many days I finally found enough time to try to update my Asus Zenfone 3 Zoom to Android Nougat.
To solve the issue, I used an original Rom from the Chinese store because it contains useful files for purpose without any conversion:
boot.img
system.img
recovery.img
I flashed all 3 IMG files.
Recovery.img that it's necessary to get original recovery without which any update can be done.
You must use a microSD and the original recovery tool to be able to upgrade your system.
The problem is that it does not seem possible to use TWRP. It is possible to install it in place of the original recovery and you can do also a nandroid backup but in practice you can not use it to install any updates and restore any nandroid backups.
Is there a custom rom that you can use instead of the original one?

Almost soft-brick my device. Need help, Emergency!!

Hey guys!
This is my first ever thread on XDA! And my problem goes like
I have a Asus max Pro m2 device. And also I'm familiar with things like custom ROMs, custom recovery, rooting and all that stuff. I have been using custom ROMs, etc etc.. from a long time. And I use TWRP as my recovery system. Recently I tried to install lineage OS on my phone, but it gave me an error 7. Then I searched on google about what is error 7. Tried all the solutions, nothing worked. Then I thought it's happening because of my phone's modem. So I searched for the latest modem file for my device, then I got a file on XDA. And that was a TWRP backup file of the Modem and the EFS. So I downloaded it and restore the file through TWRP. And from there, I'm not able to install any custom rom on my device. I tried many of them but couldn't. All of them have me an error 7.
But before that everything was fine. I was in evolution X custom rom. And that file ruined my device completely. Now I'm completely helpless, clueless. So what to do. Any expert suggestions?
PLEASE RESPOND!!!
Hi, if you didn´t solve this problem watch this video that has the solution for asus zenfone max pro m2 brick devices. Keep in mind that when you do this, the phone gonna be with the first oreo version, relock bootloader and unroot your device so you have to uptade manually.
Copy the zip ROM file to your PC and unzip it using your favorite archiver (for example, 7-zip);
After unpacking find META-INF folder and go the META-INF/com/google/android line. In the last directory you will find two files called "update-binary" and "updater-script". We are interested in the latter one;
Rename "updater-script" to "updater-script.txt" and open it in any text editor (for instance, Notepad++);
Now remove the line starting with "assert" to the next semi-colon. Usually it is the first or a few first lines in the beginning of the text file;
Save the modified file;
Rename "updater-script.txt" back to "updater-script";
Update all files you have unpacked;
Copy the modified zip-file on your phone;
Reboot your Android device to recovery mode and try to update it again. Status Error 7 should be gone.
