[SOLVED] Issues Booting on a XT925 - Unlocked device

Hi everyone,
I end up here after loads of searchs and manipulations unsuccessful...
Well here is my problem :
Edit : The problem much advanced, but is still not resolved, see 5th post for more information of current status
Final Edit : Problem solved, see the 5th post.
I have a Motorola Razr HD XT925 which is Unlocked.
I tryed flashing a custom rom on it, and failed hard.
Before failing that hard, I had some backups which were working perfectly, those, don't work anymore ...
So here is what I can access :
Fastboot (works perfectly, I can access it from my PC also without any issues)
Recovery (works "perfectly", the only thing is I cant restore any backups and I can't flash any ROM well yet, tryed Factory Reset also, does not work)
Normal boot just remains on "Warning bootloader unlocked"
By the way, by doing all that my backups have gone from my phone, so I only have em on my computer which is a bit hard when you want to try a restore (on a backup that was working perfectly before).
Another thing I noticed, when trying to Factory reset for example, It says "Unable to mount '/data'" which is a bit hard if you want to write data ^^
If anyone has an idea, feel free to make a comment, any idea is accepted since I can't use my phone at all...
Feel free to ask any question if you need more information or if you did not understand something.

Here some more infos I got while using DroidHD Utility Deluxe :
The command "fastboot flash aboot file.mbn" leads to a "error: cannot load 'folder/file.mbn'"

I managed to get a functional Driod Razr XT925 OS working by using the tool I mentioned before : DriodHD Utility Deluxe
Everything works well except those :
I can't read any backups made with TWRP before that (I mean the backups which were functionnal but that I couldnt manage to get back on).
I can't make my SIM work anymore, it says, unknown sim, and no network available when I'm trying to use my phone with GSM functions.

Managed to get my backups work again. The folder was under another name, which is why TWPR couldnt find it.
One last problem, my /efs partition has left me You already see the problem ? No IMEI around !
So I managed to find my IMEI number again and trying to use that http://forum.xda-developers.com/showthread.php?t=1960918 to write it back on my phone.
But...cause there's a but, I cant seem to use my USB drivers when I boot up in "BP Tools".
So impossible to access the phone, and impossible to write that "recovered" IMEI...
Anyone has a solution roaming around ?

Well at least I can feel like not being a total dumb ^^ Managed to install manually the driver for QC Diag Port, by selecting "Motorola" > "Motorola QC Diag Port" manually.
So, the BP tools mode can now be accessed from my computer, but here is another problem, I can communicate with the phone and even write my IMEI, but not on the phone Sounds like the entry 555 (which was totally absent) is in read-only mode :/
Here is the error given by RF NV Manager :
NvManager::writeToPhone(comPort, nvItems, throwException) -Unable to write 'NV_UE_IMEI_I' to the phone. (Parameter is write-protected and thus read only)
A clue ? Anyone ? Before I find it alone again, I think I'll soon be bald considering how I tear my hair since some hours...
Edit :
Ok so I tryed the QPST thing on a 32bits XP computer. Same problem.
I also tryed flashing my ROM into the stock one with RSD Lite, which is called like that :
9.8.2Q-8-XT925_VQU-22_USERSIGNED_S7_UCAVANQU02NA02F.0R_LSAVNQJBRTFR_P007_A004_CFC
Found it here : http://forum.xda-developers.com/showthread.php?t=2032284
Under that name :
Branding: Retail France/Retail Central Europe
Version: 9.8.2Q-8-XT925_VQU-22 FULL
Android Version: 4.1.2
Bootloader Version: N/A
Requires RSD Lite 6.0
Click to expand...
Click to collapse
And got an error (even after removing the getvar command) which is :
Failed flashing process. 2/22 flash partition "partition_signed"->Phone returned FAIL
Click to expand...
Click to collapse
Here is what the fastboot screen says :
Fastboot reason: Flash Failure
usb connected
downgraded security version
update gpt_main version failed
preflash validation failed for GPT
Click to expand...
Click to collapse
Final Edit (#Request lock) :
Ok so I finally got out of trouble.
Flashed to the stock rom with that rom : 9.8.2Q-8-XT925_VQU-22_USERSIGNED_S7_UCAVANQU02NA02F.0R_LSAVNQJBRTFR_P 007_A004_CFC
Found it here : http://forum.xda-developers.com/show....php?t=2032284
And applyed that homemade script (which gets rid of the cache memory problem before system flash) :
Code:
@echo off
fastboot flash sbl1 sbl1_signed
fastboot flash sbl2 sbl2_signed
fastboot flash sbl3 sbl3_signed
fastboot flash rpm rpm_signed
fastboot flash tz tz_signed
fastboot flash aboot aboot_signed
fastboot reboot-bootloader
echo. When the screen bcomes back on, press any key to continue!
pause
fastboot flash partition partition_signed
fastboot flash sbl1 sbl1_signed
fastboot flash sbl2 sbl2_signed
fastboot flash sbl3 sbl3_signed
fastboot flash rpm rpm_signed
fastboot flash tz tz_signed
fastboot flash aboot aboot_signed
fastboot flash boot boot_signed
fastboot erase cache
fastboot flash system system_signed
fastboot flash recovery recovery_signed
fastboot flash modem modem_signed
fastboot flash devtree devtree_signed
fastboot flash logo logo
fastboot flash cdrom cdrom_signed
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg_signed
fastboot erase cache
fastboot erase tombstones
echo. Press a key to reboot the phone
pause
fastboot reboot
Then when I came back on my phone, my IMEI was back itself like a big one
4 days of SMS came back at that time, I'm saved

You should be able to find your stock rom here (for JellyBean 4.1.2) :
http://forum.xda-developers.com/showthread.php?t=2032284
And here (for Ice Cream Sandwich 4.0.4) :
http://forum.xda-developers.com/showthread.php?t=1943879
Extract your stock rom into a folder then copy these files into this folder :
"fastboot.exe", "AdbWinApi.dll" and "AdbWinUsbApi.dll"
And about the script, write it into a file called "flash_fastboot_hybris.bat" using your favorite text editor (notepad or notepad++ for example).
Then copy this file into the stock rom folder.
Then boot up your smartphone into fastboot mode, plug it to your computer and execute "flash_fastboot_hybris.bat".
Follow the script insctructions, and your smartphone should be back to its stock recovery.
Tell me if you need some files or more information.

For my own story, when I had successfully flash with droidHD utility, I flashed back using my own script and it worked.
If it doesn't then your problem is probably different from mine (your IMEI is probably corrupted), you could try using QPST and modify entry #550 with your own IMEI.

fixed

Root Qiku Q Terra 808 (CP8692_I02), unlock bootloader & flash TWRP recovery

Hello Friends,
At last I figured out how to unlock bootloader, root & flash TWRP recovery !!
To achieve the above you should have some basic knowledge of adb, fastboot & flashing.
The usual warning... Try the following on your own risk, don't blame me if your device is dead, burnt or you lose your job because your boss couldn't contact you on your dead cell phone :laugh:.
Lets Begin !!
1) Download & install ADB-setup and Qiku Download Assistant.
2) Go to bootloader, switch off your phone and press and hold volume up button while connecting usb cable. When you see bootloader press volume up again to enter fastboot mode.
3) Go to device manager and you should see “Android or unknown” with a yellow exclamation mark under “other device”. You have to manually install fastboot driver here, just google it how to do it. You to have
go to C:\Program Files (x86)\Qiku\adb and select QK_ANDROID_ADB to install drivers.
4) Unzip the firmwares zip files.
5) Now to unlock bootloader we have flash the following firmware 6.0.018.P2.160720.QK8692.CPD but we have to force close Qiku flashing tool when flashing is at 1-2%. To do that open task manager on your pc before flashing and end Qiku flashing when the flashing is 1-2%.
6) Disconnect phone from pc and reconnect while pressing & holding volume up if you see completely black display it means now you have unlocked bootloader. Always refer to the device manager in your pc if your device is in fastboot mode as you would not see anything on the device display once you flashed the above mentioned firmware.
7) Go to the folder where you have the TWRP custom recovery. While in the folder press shift and right click and select “open command prompt here” from the menu. Copy “fastboot -i 0x1EBF flash recovery Qiku-TWRP-recovery.img” without quotes and paste in the cmd and enter.
8) Once Qiku TWRP recovery is flashed successfully lets boot the same from bootloader. While in the folder press shift and right click and select “open command prompt here” from the menu. Copy “fastboot -i 0x1EBF boot Qiku-TWRP-recovery.img” without quotes. Your device should boot in TWRP recovery.
9) In the TWRP recovery on your phone go to advance and select adb sideload and start the same.
10) Go to the folder where you have the SuperSu.zip and open command prompt here. Copy “adb sideload UPDATE-SuperSU-v2.78-20160905010000.zip” paste in the cmd and enter, without quotes.
11) Now if you wish to lock bootloader again then select reboot option in the recovery and select bootloader. Go to the folder where you have the emmc_appsboot.mbn file and open command prompt here. Copy “fastboot -i 0x1EBF flash aboot emmc_appsboot.mbn” without quotes and paste in the cmd and enter. This will lock the bootloader and you can always unlock the bootloader by following above mentioned instructions.
13) Copy “fastboot -i 0x1EBF reboot” in cmd and enter. This should reboot you phone.
14) If everything went well you should see supersu app in the phone. You can also check by an app called root checker from play store if you have successfully rooted your device.
When you have the unlocked bootlader there would be no display when you're in fastboot mode hence you have to check in device manager to ensure that the device is fastboot mode. Plus while booting or rebooting there would not be any boot animation but only the boot sound. This is due to the unlock bootloader.
Contents of the download link :
A) Stock firmware for the device v21. incase you have trouble and wish to flash stock firmware.
B) Firmware to unlock bootloader 6.0.018.P2.160720.QK8692.CPD.
C) 8692_I02 individual .img of stock.
D) adb-setup for adb & fastboot drivers
E) Stock aboot .img to lock bootloader.
G) Qiku download assistant.
E) Qiku TWRP recovery
F) SuperSu.zip.

You can change the same in buid.prop once you're rooted however you would not just be able to flash and boot Andoird 6 Chinese firmware on your device. I have tried the same but it does not work.

Not at all if you ask me as I have been playing with my device for past 8 months or so. I did hard brick my device at several occasions but was always be able to recover it. During those hard brick the device goes into fastboot mode on it's own or one can press and hold power key & volume up to force the device to go into fastboot mode which it always does.
To recover the device from hard brick it needs to be in fastboot mode whether locked bootloader or unlocked bootloader. If the bootloader is locked then the official tool can flash the stock firmware and boom... The device will be Alive again. Incase of unlocked bootloader it's just the matter of flashing the firmware .imgs through fastboot mode:good: or if you've taken backup in TWRP then just boot TWRP and restore your device.
One warning though... Do not try to flash any other OEM's firmware as I am not sure what would be the outcome as I have only tried our device OEM's firmware. Yes can try porting other custom rom to our device as it only involves flashing system.

I would love to help you but I hard bricked my device about 2 days ago while playing with emmc_appsboot.mbn . As you know to recover the device we need rawprogarm0.xml, patch0.xml etc and the stock rom doesn't contain any of the said files.
Fortunately, I am in touch with another Qiku user and I have already written to him about your requirement. I have also requested to him to respond to you on the xda forum itself. Let's wait for his response.
Besides, I was wondering if you know any ways to get the rawprogram0.xml, patch0.xml etc from a working Qiku for recovering my hard bricked device?? or any other method which can help?. Can Qdart tool help in anyway??.
I have searched Qiku Chinese forum but unable to find the required files.
Any help would be much appreciated :fingers-crossed::fingers-crossed::fingers-crossed: !!

Sure i ll send those files to you in a day or two!

You mean you had a device QK8692_M02 and you flashed QK8692_I02 and booted normally but when you tried to go back to your QK8692_M02 it hard bricked??
Well my friend I am afraid but now you need to reflash QK8692_I02 to use the device and you might not be able to go back to your Chinese OS now. There was a similar case where this gentleman from Russia did the same thing to his Chinese Qiku device and he was not able to go back to Chinese OS now. There is something with the QK8692_I02 OS I guess.
I was able to boot v109 of Chinese OS on my QK8692_I02 and the v109 rom & the instructions are there on the given download link. I was in process of being able to use Chinese OS on my QK8692_I02 when I hard bricked my device . Now I need emmc image of Qiku to unbrick it and then I can continue my research and might be able to give solutions to the issue.
Let me know if you could get me that emmc image it would be just 200-300 mb file and the same you can upload it on google drive.

Yes! You can use follow method:
1. Create a new APN
2. If you see on network icon is E not 3G that not support my EFS model(8692_m02) for you. So you can try a qcn file from same model.

[SOLVED] SM-G930FD: DRK error + locked bootloader = bricked phone?

Hi all,
After screwing up my efs partition, I was finally able to make my phone boot with a stock ROM by installing TWRP and no-verity-opt-encrypt (none of the other options in this guide worked).
But it seems after re-installing the stock ROM the "OEM unlock" option was disabled somehow and after powering off my phone it didn't boot again because of TWRP. I reinstalled the stock ROM, but the DRK error is back.
So:
- I can't boot the stock ROM because I'm getting the DRK error.
- I can't install TWRP and no-verity-opt-encrypt because OEM unlock is disabled.
Any idea about what I can try to fix it? Or am I completely screwed up?
EDIT: I forgot to mention that I still can flash and boot Combination ROM, but there's no way to unlock the bootloader from there as far as I know.
EDIT 2: Solution

I don't fully understand your post, let's make something clear:
Flashing stockrom via Odin/KIES gives you the DRK Error after/while booting
You currently can not flash TWRP, as OEM Lock is on
You currently do not have TWRP because you flashed the stockrom
You do not have a Backup of your /efs partition
AFAIK things like the IMEI are stored in the EFS partition, and it really isn't a good idea to do anything with it unless you have a backup

Hi jaannnis, thanks for your reply.
Yes, everything you say is correct.
Regarding the third point, I had TWRP, but I replaced it with the stock bootloader after the phone stopped booting with TWRP due to OEM being locked.
I thought I had a backup of my EFS partition, but it turned out to be corrupted somehow. But even if I had a valid backup of the EFS partition, how can I restore it with a locked bootloader?
Anyway, the IMEI is not an issue. Actually, after my EFS partition became corrupt, I was still able to use restore the IMEI using Combination ROM and then boot the stock ROM using no-verity-opt-encrypt and use the phone to connect to the network with the correct IMEI.

Solved!
OK, I managed to solve it!
I solved the steps in this post in a Spanish forum.
These are the steps for those who don't speak Spanish:
Install Combination ROM and check the IMEI is correct by typing *#06# in IME as explained in the XDA post by CuBz90 mentioned before.
Untar BL and AP from stock ROM and tar them again containing only cm.bin and sboot.bin in BL and boot.img and system.img in AP. This somehow allowed to boot the stock ROM bypassing the DRK error but with some parts missing like Recovery or Google Apps.
That's anyway enough to be able to enable "OEM unlock".
After unlocking OEM, I was able to flash a full stock ROM and TWRP.
Apply no-verity-opt-encrypt from TWRP as explained in the XDA post mentioned before

is it easy for you to upload BL and AP which you created because I don't know how to create them as you write.

I think you should usually use a stock rom specific to your phone because of the modem drivers and all that stuff, but for this purpose any version may work since you don't actually need to make phone calls and it's only for unlocking the OEM.
If you use Windows, you can use 7-zip to untar the AP and BL files included in the stock rom and tar new ones with the files I mentioned.
I did this almost five months ago and I no longer have the AP and BL files I used, but I still have a copy of the stock rom for my phone (G930FXXS1DQHM_G930FOJV1DQEB_XSG).
I will try to pack the special AP and BL files again and upload them, but it can take ages with my upload speed. It won't probably finish before tomorrow.

Shared on telegram, thanks!

I'm not using qcn
not edl mode using
1. Flashing 7.8.23
2. 7.8.23 root ( patched_boot.img flashin using fastboot mode )
3. Usb diag mode on (dialler open trying or adb using su diag mode open )
4. Dualwriteimei using and restart phone aaaand booom imei restore (dualwriteimei is youtube searching only small size program and very very best )
5.Phone fastboot mode on and 8.1.10 rom flashing and booom

New telegram link:
https://t.me/joinchat/G1MMfkc6EbEZL-62Ii5YmA

thats not permanen, at last for me, maybe work on 7.8.23, but after update via ota or fastboot, after reboot or reset factory on setting imei unknow again
my solution right now, using custom rom, with august security and push modem file from latest stock rom for update baseband

It works, but if you want to update whole system, you have to backup partitions modemst1, modemst2 or EFS in TWRP, after you backup that, flash the new oreo firmware without data, if dont starts, recover the EFS and try again, if dont, do factory reset and if you haven't IMEI yet, restore de EFS, the problem here is, if you restart your EFS would be corrupted, so you have to restore the EFS and force update to the lastest update with EFS already installed, if youre lucky your EFS never be corrupted again

In my case everything is working fine
No issue upon updating or restoring

than so much raj bro 100% working method

I followed this procedure some time ago and haven't had issues. However today I flashed a new Oreo image and suddenly my IMEI was 0 again.
I restored my EFS partition using TWRP and now everything is fine again, except that my smallband version is back to 953_GEN_PACK-1.... which I think is the version that shipped with tissot_images_7.8.23_7.1. I wonder if it's a problem to run with an older smallband version?

Someone there who can help me fixing my IMEI? I have pushed the "flash_factory.bat"-button...
Mi A1 is working and rooted, no 30sec boot loop anymore, but QPST recognize my mobile just for secondes.
I'm holding my IMEIs in hand but unable to get them into QCN sinced days.

i was Restored persist.img via twrp terminal but my phone still restaring continously

Im sooo stupid kiddo :crying::crying::crying:

Bro my telegram @Byramklc add me
Sent from my Mi A1 using XDA Labs

While I did finally manage to restore my IMEI, I found your "guide" really confusing.
You should without a doubt write it better, so people might understand it better as well.
I've been doing custom Android stuff for around 10 years. While I have never developed anything, I have gotten as far as to the point to where I have had to edit files and input hex.
You should _really_ mention when and how you use the files you provided.
You should also provide the "how-to" on editing the files.
I finally got it to work, but I had to read three different guides before I got it.
Still.. Thanks

Can someone confirm that PSN and FSN will missing if using flash_factory ?? (FSN&PSN can be found on *#*#6484#*#* Version Information)

hello guys ,thanks for the guide, i've restored my imei but the mobile data network still wont work, what it can be?
EDIT: I've resolved by using a newer version of qpst software, the 2.7.472.4 one

I managed to get IMEI back wifi and bluetooth working but sim network lost.
Sent the mobile to service center and they changed the motherboard.
Is this the only solution.......

were you able to restore sim network as well???????
If yes pls write a complete guide with all the tools and files used

[need help] asus zc520kl [x00hd] any working rom with twrp

Update/Solved:
Currently the only way for people who deleted their OS completely in this phone model X00HD/ZC520KL is to restore the official firmware.
You can ask for a backup recovery folder in XDA Forums ( https://forum.xda-developers.com/zen...help?nocache=1) if you do not have made a backup with people who have the same phone model. You must have TWRP previously installed and bootloader unlocked. Flashing the official firmware via .zip files is not working with twrp, you must restore the folder. After having the files needed, your recovery folder will not appear on the RESTORE section so follow this simple tutorial to make it appear there (https://youtu.be/trlG3ZxwQxI)
This method will bring your phone back to life if you're stuck in TWRP Recovery Mode with "No OS installed". This method is working and it's the only way for you to use your phone again until developers create custom ROM's for this model.

Hello, I tried your solution. It did not work. I keep getting Error Number 7 when flashing the ROM. Plus I also tried to delete the assert line in the uptader-script of the ROM you gave me the link after learning from a tutorial how to solve Error Number 7 and after that I got another error: Invalid Zip Format. I don't know what do to more, is this ROM link really compatible with my device? I need urgent help.

Thanks for the attention. I already tried tons of ROM's including the official one for this phone. I keep getting Error Number 7. Sometimes when I force an installation editing the uptader-script file it seems everything is working fine, but at the end of the ROM flash process the phone reboots and goes back to TWRP like everything had never happened. I have never seen a successful feedback, just the "Failed" message or a unexpected reboot that goes back to TWRP.
I don't know what do you mean with unlocking bootloader as I have no ROM installed and always I turn ON my phone I go to TWRP automatically. My TWRP version is 3.1.1.

Not working, as I said before, I've already tried to solve this Error. Either 3 things happen: the installation seems to be running good but at some point the device automatically reboots to it's original condition of TWRP (Liniage OS flash and after editing the file to solve Error Number 7 + I get a message saying "Invalid zip format" (Official Asus Firmware flash after editing the file to solve Error Number 7) + I get Error Number 7.

Backup ROM
Hi, I have the same model and I have TWRP as well. I think I can make backup of my ROM an upload it so you can install it on your phone, would that work for you?

Hello @pantarz, yes, give me your backup ROM you have in your phone, it should work on mine. I'm really thankful to see people like this these days. Just need the .zip file for the ROM. Thanks in advance.

Hi @ANDROIDMASTER67, @pantarz I also break my phone ZC520KL ( X00HD ). It shows "no os installed" and "error 7" when I try to install a ROM.
Can you please help me fix my phone? If there is a backup that I can get please let me know.
Many thanks in advance.

I've managed to fix it by doing the following:
Copy the original recovery from a firmware package.
