[Solved][PX5 GS] Can not use custom recovery - MTCD Android Head Units Q&A

I would like to flash custom recovery -> in order to use custom ROM -> in order to gain split screen in my 7" device (ehhh)
I have root, adb, access to bootloader (everything what I need..) but it does not work in default way.. - I mean flashing just by fastboot flash recovery TWRP.img
I have checked those TWRP builds
https://twrpbuilder.github.io/downloads/twrp/ (type px5)
Flashing worked fine (no error, success message)
But after rebooting to recovery I still have original recovery. Note: I have to reboot to system, and then to recovery by adb command. There is no reset button on my device, I can only enter bootloader by long pressing volume button while booting.
I saw `backup` partition in my device. Is it possible that system is reverting recovery partition? How to fix that so I can use TWRP

That TWRP don't work in PX5. I'm trying to get it work

Good luck!
Please inform me if you will succeed.

Have you first tried to boot TWRP without flashing? I'd most certianly want to try that before flashing something.
Did that work?
This might sound super silly, but did you also unlock the bootloader first? (Sorry, I'm not familiar with your specific device so this may or may not apply in your situation)

Any advice is welcome thanks
But without unlocking bootloader I would not be able to go to bootloader and use fastboot tool right? So I concluded it is already unlocked.
I tried
fastboot boot TWRP.img
Image was downloaded and booted (success message was printed in console), I lost connection with device so it went in some other mode then bootloader, but after 30 seconds of black screen I have switch power off and back on to restart.

I tried using A8 roms but I can not flash it with original recovery.. It requires device name be PX5 (I have rk3368). If I remove checking from rom updater script, signature verification fails.

I have tried recovery from Malaysk pack (extracted from update.zip), tried RecoveryInstaller from malaysk, lot of TWRP which I have found in web.
Nothing worked.
However as a last chance I used bootable SD from Malaysk - recovery (for android 8) successfully installed, Malyask rom installed. Im happy now
BTW. If you want you system to not revert recovery - you need to remove "/system/recovery-from-boot.p"

I mean I already have Recovery v8. So I was been able to flash custom A8 ROM.
However if you would implement TWRP please message me It is always better.

Maybe you are right. But at least it is easier to backup / restore whole device with TWRP.

How to Downgrade bootloader 41.1A to 41.18 or 41.19

i want to Downgrade to version 41.18 or 41.19
anyone know ..??
please share it
thank you

Me too
My bootloader v 41.1A I downgrade 41.18 Help
Why do you need to downgrade? Messing with Bootloaders can destroy your phone.

Bootloader cannot be downgraded. You're stuck on w/e version you have currently installed.
Okay so I'm stuck on 41.1A and my phone will continue to restart itself and then stuck in bootloop till the battery dies... and then when I connect it to the charger boot's up normally...
@lost101
Can you please let me know how to check bootloader version?
I am using Moto G XT1033 model(Asia).
It was updated to Lollipop 5.0.2 by Motorola Stock Lollipop update.
Later on I had unlocked bootloader and downgraded it to Kitkat 4.4.4 using this thread.
I don't have any clue about current version of bootloader in my Moto G.
I want to try Lollipop 5.1 Optimized stock rom link here, so just wanted to ensure compatibility of bootloader so that my phone works after flashing it.

Enter bootloader (hold volume-down while turning it on), read text on screen (second line).
I too want to know if there is a way to downgrade or at least reflash my damaged bootloader which is causing weird behaviour.

I have the exact same problem.
Stuck on 41.1A
Was on a slim6 rom before. Tried to return to STOCK_ASIA_RETAIL. All fastboot commands successfully executed but no apparent change. I have the exact same wallpaper, the same layers RRO navbars, everything. I would not need to go to STOCK but since the slim installation is unstable and everything force closes, the phone is unusable.
Additional note: Somehow even TWRP is stuck in the splash screen, so cant flash any other ROM. Even tried to access TWRP using adb, but the TWRP service fails to start.
I fastboot flashed phillz recovery, stock recovery & newer TWRP versions, but nothing happens. Phone still stuck in TWRP screen.
To my surprise I was able to pull my personal files from the internal SD using ADB (which still works btw).
But I'm left with a phone in a zombie unusable condition, it just doesn't react to anything.
Any help from the XDA community would be greatly appreciated. I am still keeping my fingers crossed, so that one day a guide comes up to brick my device (STOCK 5.1 bootloader) and unbrick it using some sort of unbrick tool.

Creating such a zip is possible, but flashing it may either not work or hard brick your phone.
How to install working recovery on 41.1A bootloader
I had the situation on my Moto G XT1039 where I had formatted the partitions on my phone (using my old CWM recovery), then flashed the 41.1A bootloader, but 41.1A would not allow me to flash any recovery.
So I had a working bootloader, but no recovery and no OS. And apparently no way to install a recovery, to install an OS...
I got the phone back like this:
- Flashed 4.4.4 stock manually using the bootloader (if you do this, DO NOT flash the 4.4.4 motoboot.img, according to everything on here that will permanently brick your phone; I am not sure about partition gpt.bin - I flashed this, but I was already on the 4.4.4 partition layout anyway). Do flash boot.img, that is the OS boot.
- So now I had a bootable phone OS (back on 4.4.4 again, with a flickering screen), but still no recovery.
- From the bootloader, I booted into an old recovery which I knew had previously worked with my phone:
Code:
fastboot boot clockworkmodrecovery.6051.peregrine.img
(this boots into a temporary copy of the recovery, without actually installing it on the recovery partition).
- Using that, I installed the SuperSU binary.
- Then I booted back into my 4.4.4 OS, installed the SuperSU app, checked it was working, then installed the TWRP Manager app (which requires root, hence the previous steps), then used that to successfully install the TWRP recovery on my phone.
From there I now had the correct recovery in place to flash the 5.1 Optimized distro (which I would definitely recommend - clean, stable, excellent battery life!).
Yay!

I hope I haven't misunderstood, but isn't the whole point of this thread that the 41.1A bootloader won't let some poeple (including me) successfully flash anything to the recovery partition? You can run the command, but the recovery won't boot up. At least that's how it was for me.

I see. So "fastboot boot" worked, but "fastboot flash" wouldn't write anything? In that case you could probably also have used fastboot boot with TWRP and then use TWRP's "install image" feature to flash it.

Thanks! I definitely tried that first! Maybe this bit I didn't make clear in my post, but actually:
- fastboot boot was only working for me with older recovery ROMS, i.e. the older CWM recovery which I mentioned, which I had lying around from when I first rooted my phone on 4.4.4, and also - not that it's much use - with the recovery in the 4.4.4 image, which just brings up the dead Android logo
- fastboot flash recovery was not working at all, not even with the recovery roms which would boot with fastboot boot
- but fastboot flash to all the other partitions seemed to work fine (I could see that it seemed to be working because I was able to flash different logo.bin files to change the phone logo which shows before the phone tries to boot into recovery or OS) and as per my post this was how I was able to get my phone back eventually
This thread was the only place I could find which seems to represent people having the same set of problems, so I thought the above workaround might be useful in future to someone in the same situation.

That doesn't make any sense. Not that I don't believe you, I just can't explain how fastboot could fail writing recovery but succeed in writing a different partition.

It appears to succeed, except that it gives the 'mismatched partition size error' on the bootloader screen at the end of flashing. (Although other posts seem to state that this is normal for a non-strock recovery?)

Yes, I've got that one too, but my flashed recovery then worked fine. However I upgraded my bootloader by installing the complete 5.1 stock ROM, maybe your bootloader update was somehow incomplete.

Booting TWRP Advice

HTCDreamOn said:
A word of advice: I strongly recommend temporarily booting any images (be it recoveries or kernels) you are about to flash to your device. This is simply a case of using the command "fastboot boot blahblah.img" whether blahblah.img is a recovery or kernel.

We know you can boot to TWRP vice flash to your device by using the command:
Code:
fastboot boot twrp.img
But how do you proceed from here? Are you required to use ADB commands at this point or can you unplug your USB cable and use TWRP as if it was installed, I.E. , back up current ROM, and install new zip.

Sorry if I wasn't clear. Yes you can unplug usb and use as normal, it just means twrp isn't flashed to the device so it won't be there when you reboot.
I just recommend this step because I'm paranoid. Once you've confirmed the image works you should reboot to bootloader and fastboot flash the image, then you'll be able to boot into twrp whenever you want.

This is a good step to do, and if the device supports it it should be used... for example the Moto G (if unlocked) fully supports fastboot boot commands, devices like the HTC One M7 do NOT support this anymore...
To the OP, what is really happening here is that TWRP or the boot.img (kernel) is being loaded from USB into RAM and executed normally, instead of the standard /boot partition which is skipped when executing fastboot boot. TWRP (and recovery in general) is really just a specialized micro-sized android distribution and when started via fastboot boot is executed as if it was the boot image. Once the image is transferred into RAM, the boot continues normally per the instructions of TWRP or the boot image, and no further action via USB is required. USB is just the medium to load the image into RAM and nothing more.
fastboot boot - used to manually load a boot image (or recovery) and execute from RAM, it is not flashed to the device, on the next reboot it will return to it's previous state
fastboot flash boot/recovery - used to actually flash the boot image or recovery image to the it's appropriate partition on the device, it does not execute it. On a reboot or factory default this information will stay in the device.

Thanks. So it seems there is no reason to ever flash TWRP unless you don't want the PC dependence to use the TWRP tool.

Well, sort of... but the point is once you flash anything via twrp, you are no longer stock, so why not flash twrp to make it easier to flash other things?
The smartest thing would be to unlock, boot TWRP, make a nandroid backup before you do anything at all, then flash TWRP and do your thing...

I understand what you are saying. The only flash I planned on was SuperSU. I thought when a system upgrade is available, I could simply use SU to unroot and be ready for the update. Would this work?
If I followed your recommendation, could I feasibly, flash TWRP, then when an upgrade is ready, flash nandroid backup (which I assume removes TWRP) then accept system update, then re-flash TWRP. I could restore apps by using TB. Does this make sense? Or does TWRP remain in place after flashing nandroid backup?

TWRP remains in place after restoring a nandroid (I think, I haven't installed on my Moto G, but in most devices it doesn't backup/restore recovery), but you can easily restore the original recovery via fastboot.

Hey thanks for helping to answer this, your explanation was much better I thought it had something to do with loading into RAM but wasn't sure. I didn't know some devices don't allow fastboot boot commands though, I've always relied on them. Part of the reason I'm avoiding htc now.
@purplepizza I agree with everything acejavelin has said: essentially you really do want to make sure your have twrp flashed.
To answer your nandroid question: It basically just takes an image of the partitions you choose, usually /system, /data, and /boot (where kernel stuff is) which is the least you need to boot back with all your data. It doesn't backup recovery and when you restore it doesn't write anything to recovery, so yes twrp will still be in place. In general you should only ever flash stuff to the recovery partition whilst in fastboot mode (i.e. using fastboot flash recovery recovery.img), I know on some devices you can flash recoveries as zip files in the recovery itself but you shouldn't.
I've seen quite a few people querying about the 6.0 OTA: in short, I wouldn't worry about it because once they start rolling out, people always catch the OTA and post here on xda. You can flash that and it'll return you to stock 6.0 anyway, at which point you can reroot and everything if you want.

So what is boot? I know I am kind of going back to my previous question, but if I restore boot, is that the boot loader? I would assume this would not commonly need restored?
And I now assume the bootloader is completely independent from recovery.

It is not the bootloader... It is the /boot partition of the phone, basically the kernel and RAM disk. If you screw things up and need to restore, you typically want to restore /boot, /system, and /data, and occasionally /cache (if you want to restore to save time and get an exact duplicate of the previous image, otherwise many people skip /cache and let it rebuild on the first boot which takes 10-15 minutes extra).

Rebooted and flashed TWRP, see below:

sending 'recovery' (7772 KB)...
OKAY [ 10.635s]
writing 'recovery'...
OKAY [ 0.141s]
finished. total time: 10.776s
All seems OK.
Scrolled to recovery, selected recovery. TWRP was there. I then powered down.
After that I held power and volume down, system boots to dead Android with message “No command” Held power then volume up, I see stock boot loader. Is TWRP flashed somewhere or is it gone? So what did I do wrong.

Any recommendations how to proceed?
I also need help with my soft bricked moto g3
Moto g3 (xt 1550, Indian dual sim 16 gb version)
I officially upgraded to 6.0.0 via ota and my objective was to root my phone and use xposed modules. I am not interested in any other custom rom (I'd rather keep stock rom just for moto display and ota upgrades) or custom recovery like twrp(I'm afraid it may cause ota upgrades to fail).
I used the method described here in the question- http://android.stackexchange.com/qu...rsu-using-play-store-versus-a-custom-recovery
So I first successfully unlocked my bootloader using the official motorola method.
I then proceeded to use google's backup settings to re-install all the apps that were uninstalled due to unlocking the bootloader. I also put supersu.zip version 2.46 on internal sd card.
I then proceeded to (without rebooting) enter fastboot where i used minimal adb to temporarily boot into twrp version2.8.7 r5 (link - http://forum.xda-developers.com/2015-moto-g/orig-development/twrp-twrp-moto-g-2015-t3170537 ).
Once in twrp, I located and flashed the supersu.zip. It flashed successfully. I procceded to clear dalvik cache and then after clearing cache I tried to reboot my phone using twrp.
However, it did not go beyond the "Warning - Bootloader Unlocked" screen that you get on unlocking a motorola bootloader. I left it for over 10 minutes (usb was still plugged in, I had >80% battery) but it did not proceed.
Long -pressing the power button causes the phone to vibrate and again attempt to boot, stuck at the same initial screen. Adb quite understandably does not work here.
I can press vol down+power and enter fastboot , where adb works fine.
I can enter stock recovery from the fastboot sceen too.
Using adb in fastboot, I am able to boot twrp . In fact, I tried to re-install supersu.zip. I retried version 2.46 and then tried version 2.56. On all occcassions, it was able to successfully flash it, but gets hung on the initial boot screen.
USB Debugging is also enabled, and I have a backp of my sd card data.
I tried taking a backup of the system and apps in twrp (3 gb in total) and tried to reflash it, but it still hangs at the same screen.
Is there any way I can unbrick my device and- (in decreasing order of preference)
1. Keep my stock rom and recovery?
2. Keep stock rom with twrp? (It should not be a problem)
3. Custom rom with custom recovery - perhaps official cm. Least preferred as I want Moto Display and stock/vanilla android.
Also, is SELinux involved anywhere with my phone getting bricked? I also read that a custom kernel is required for rooting 6.0, which I don't have. Supersu Version 2.56 is said to prevent soft bricks if the kernel is incorrect (systemless root), yet even after flashing the newer one it is still bricked. Where am I going wrong? What should I do? Thanks in advance! :good:

I have not rooted yet. I guess I can try by booting TWRP then flashing SuperSU.
Can you think of any reasons not to try fastboot again the re-flash TWRP?

I didnt get anything from the post. you have to be little bit specific.
i mean you
1. unlocked bootloader(fine)
2. installed twrp(also fine)
3. installed cm13(great)
4. you reverted back to stock rom??? How from twrp, flashfire or fastboot.?
and now how are you trying to install twrp? from fastboot?
Flash twrp image with fastboot, start TWRP, reboot recovery within TWRP, then twrp sticks... profit.

TWRP is not sticking...
1) Start the bootloader, flash TWRP in fastboot with the command: fastboot flash recovery twrp.img (Replace twrp.img with the name of the TWRP img file)
2) Press VOL DN to start Recovery and select it, TWRP should start... When prompted if you should allow changes to system, say YES or allow or whatever so that is allowed to mount system as read-write.
3) In the TWRP main menu, select Reboot, then Reboot - Recovery
4) The device will restart and TWRP will start again, if asked to allow changed changes to system again, allow it
5) Go to Mounts and make sure Mount System Read-Only is NOT ticked
6) Press Home, then Reboot and Reboot Recovery again
TWRP will start again and be set, it will not go away unless you flash something with a recovery.img in the file (custom ROMs do not normally contain this file).

At what point? What command are you using to perform the flash?
I'm sorry... I've just done this on numerous G3's and what you are describing doesn't just happen for no reason... either the initial flash was done incorrectly, the process to set it was not followed, or there is actually a defect in the device (which is unlikely if TWRP boots even once after bring flashed).

NEVER USE KINGROOT OR KINGOROOT on a Moto G3 with Marshmallow, it will soft brick... We have seen at least a half dozen specific examples by experienced users... Somehow you got lucky, but I would never recommend this method to a user.
Now, once rooted Flashify is a viable option.

[Guide] BQ Aquaris M10 (freezerhd) twrp & root

Hi,
as I did not find an English guide for rooting a BQ Aquaris M10 tablet and had some problems when trying to root my tablet, I want to post an guide how to root this tablet.
First of all:
- This guide is just from my experience and is not thoroughly tested. It's on your own if you risk bricking your device.
- If you get stuck in the process, in nearly all cases you can revert to stock with the MTK flash tool (can be found on mibqyyo.com) and the images provided by BQ on their website.
- I could not unlock the bootloader with the 1.X-Images (Lollipop), as the VolumeUp-Button didn't work in fastboot-mode and you need this button to confirm the unlock.
- Booting into recovery from start with VolumeUp and Power-Button. This doesn't work with the 1.X-images, too.
- This guide is not intended for users without experience in unlocking/rooting a device. If you don't know how to use adb, fastboot, recovery and things like that, don't try it!
- You will loose all your data during this process!!
Guide:
Modify boot.img, flash new firmware
SuperSU in systemless mode doesn't work on stock image, as the SuperSU installer can't extract boot.img. You have to repack boot.img.
I tried a SuperSU installer without systemless-mode, but device didn't even boot anymore afterwards.
This guide is derived from a Spanish tutorial on the HTCmania-forum ("Root M10 HD Marshmallow") by yquepongo. Thanks to him!
Get a firmware for your device from the BQ-website (should be Marshmallow, see above) and unzip it to a directory.
Extract the boot-verified.img in the firmware directory with a bootimg-extractor. There are various tools available.
I used bootimg.exe, because this was explained in the mentioned thread and I even used it with wine on Linux and it went well.
Search for cpiolist.txt in your extracted boot-verified.img and delete the first two lines:
mode:mtk
mtk_header_name:ROOTFS
Repack boot-verified.img and put it back in the firmware directory.
Flash the modified firmware with the MTK flash tool according to the tutorial on .mibqyyo.com (Title "Hard Reset for the smartphone range Aquaris and Aquaris E"). In short: Disconnect device, start Tool, load scatter file from firmware directory, choose firmware upgrade, start download, connect the device in power off state, download will start automatically.
This will delete all your data and put the device back to factory rom (hard reset)!!!
If you don't want to flash the complete firmware, you can flash only the boot-verified.img with "Download only" in the flash tool. I didn't try this and don't know if this is working.
Start your device, don't activate any security settings to prevent encryption of data partition.
Unlock bootloader, flash TWRP, install SuperSU
Enable developer settings on device and activate "OEM unlock" in developer settings.
Reboot into fastboot (adb reboot bootloader) and unlock bootloader (fastboot oem-unlock).
This will delete all your data!!! Reboot your system afterwards to make sure everything is still ok.
Do not activate any security settings and make sure your data partition is not encrypted!
The existing TWRP-image can't handle an encrypted data partition, you will end in a boot loop and have to start the whole process again!
Double check, your data partition isn't encrypted. (Settings - Security)
Reboot into fastboot (adb reboot bootloader) and flash the TWRP-image from the TWRP-site (fastboot flash recovery twrpxxx.img)
After reboot TWRP should start.
If you have checked that everything is ok (I would recommend a reboot into normal mode), you can install SuperSU with the standard-installer-zip in TWRP.
If you didn't modify your boot.img, the installer will give a warning that it cannot extract boot.img and you will not find any SuperSU on your system.
If you get stuck in bootloop afterwards you can start anew and try it with another image flashed with MTK flash tool. (Firmware 2.2.0 from December 2016 for freezerhd worked in my case)
Maybe some steps could be shortened, but I haven't tried it.
hi zrfl,
i have a bq aquarius m8 with mm os.
the m8 has the same resolution (1280x800)

i will also root my m8 but i cant extract the boot-sign.img.
all tools fails.

update:
yesterday i opened the bootloader. the volume button works in fastboot-mode.
also i can unlock the boot image with the tools from: https://forum.xda-developers.com/showthread.php?t=2073775

Sorry, but I can't help you there, as the M8 seems to be too different to the M10: I didn't have to unlock the boot.img, it was easy to unpack.
hi zrfl,
thanks for your reply. i contacted the developer osmOsis from the android image kitchen.
he will implement the bq specials in his tools.
more in the AIK thread: https://forum.xda-developers.com/showthread.php?t=2073775&page=108
this is the only way to root this device !!
thanks a lot ...
Thanks for this tutorial.
I've followed all the step, I'm able to flash the new recovery from the TWRP website but then I do a
Code:
fastboot reboot-bootloader
but the device reboot normally, just with a warning message during boot saying something like "This device is unlock and can't be trusted, it will boot in 5 seconds".
So I'm unable to access TWRP recovery, I guess when the device reboot it override the recovery partition because if I do a
Code:
adb reboot recovery
I end up in the Android recovery not TWRP.
Any idea ?
Thanks

Sorry, I have done this a long time ago and don't know what could be wrong:
You have the correct message, so unlock was successfull
You try to reboot in fastboot, so you flashed TWRP correctly in fastboot-mode
And I don't have the device at hand to try it myself. But I do have a few suggestions, what you could try:
Don't try to shorten procedure with unlock and flashing of TWRP at once. I'm not sure, but I think I had problems when I tried this. So do a normal reboot after unlock, before booting again into fastboot and flashing TWRP. (Now you have done this already )
I don't remember the proper boot command after flashing of TWRP. But
Code:
fastboot reboot-bootloader
doesn't make sense: You are already in bootloader.
Is there a boot-option in the bootloader where you could choose recovery?
Otherwise better power off and use the key-combination for booting into recovery: VolumeUp+Power.
I think, you have to repeat the procedure, as recovery seems to be overwritten: Boot into fastboot, flash TWRP, reboot into recovery. And avoid normal booting before first boot into TWRP!
Did you use the newest TWRP 3.1.0 from March 8th? I haven't tried this yet, so there could be the problem. You could try the previous one: 3.0.2 from last year.
Thanks, I succeed with the combo key (power + vol up) directly after the reboot process
Perfect it's working great now !
I did exactly what you wrote but SuperSU won't install because it cannot extract the ramdisk...
Hi @zrfl
Thanks for your posting!
I did as you suggested and successfully unlocked bootloader and installed TWRP 3.1.1. Your hint to modify the boot-verified was extremely helpful, as I wouldn't be able to unlock the bootloader otherwise.
However, I did not manage to install super su. And boy, I tried many different versions od regular/system/systemless supersu, each flashed according to the respective how-to.
I ended up either in a bootloop, or get stuck on the Android logo at boot.
Flashing goes well until this step:
"Decompressing ramdisk
--- Failure, aborting"
I checked ramdisk compression of boot with Carliv image Kitchen and it tells me that it already is set to "gz" and not another compression TWRP can't handle.
Please help me on how to flash SuperSu.
Thanks and best
Tom
There is something wrong: TWRP does not need a modified boot.img.
Maybe newer ROM-versions are different.
Solution for geting root on BQ M10 FHD on stock rom 2.6.2: Start with a fresh system and install magisk beta (not stable), reboot and root is granted!
tanks a lot to @scafroglia93!
Are there any Custom ROM's
For this Tablet like CM/LineageOS AOSP etc?
Googling reveals nothing and Considering all the kernel mods like hardcore and Ubuntu touch I find it hard to believe that nobody has built one of the later.
I've been searching for custom ROMs too. Apparently, there are none available at present. However, I'd highly appreciate lineage rom.

I haven't tested fastboot but it should work. TWRP works 100%
Thank you very much, you are a life saver!!
I was stuck in a TWRP loop.
I tried flashing through TWRP but it didn't work but the fastboot method worked like a charm!
My phone is running again.
Thank you very much.

For some reason on my unlocked nokia 1 it started to ask password after flash and boot and gkeyboard always crashes on boot. So, I thought flashing fresh userdata might help.

I wrote in the instructions...
If you get a password just enter a random one, then it will ask you to wipe the device, click ok and it will reboot to recovery and then wipe userdata and boot fine.
just make sure you flash the recovery.bin and not twrp before you wipe

Same happened to me. I solved it by a hard reset via the stock recovery.
Make sure you flash the recovery.bin like Sooti said.
Wiping through twrp doesn't work.
Nice, working twrp for Nokia 1.
I buyed this phone today. Waiting for customs
A little warning.
It looks like the recovery.bin I took from another nokia 1 device doesn't match the checksum check which causes a failed during ota updates, please only flash this rom if you soft bricked your device.
If anyone can get me TA-1060 stock recovery image that should solve it. for now you can't update the phone until a fix is found
I have Nokia Ta 1066. Will this rom work on mine? Also I read somewhere Ta 1060 is single sim variant. What about the second sim?
Has anyone with TA 1066 tried it?
Thanks. Both methods work fine. Don't ask how I found out.....
Can you share how you managed to backup stock recovery file. Maybe after all the steps above we can flash our own device recovery to make ota work again...

Hey guys i have a TA-1056 and after unlocking bootloader and flashing TWRP it booted to recovery and came up encrypted, after looking around the only solution was to format data, afterwards when rebooting it always boots to recovery, i tried flashing this zip and i get the same issue and i can't find the stock ROM for the 1056 anywhere online, can anyone help me out? i really appreciate it

Sir, is that possible to get a stock rom of TA 1056 ?
I have searched everywhere but whole thing available over net just left my phone bricked. All i need is a working rom source. Even if that’s a custom rom too to flash via sp flash tool. Thanks in advance
Can any please repost the firmware , the link isn't working
