Did factory reset rooted XT 1799-2, now phone only boots into recovery mode

Hi,
My previous post relates to this one. Due to that problem I got, I had to factory reset my device to get my camera working again. However, instead, my phone rebooted into TWRP and would not boot system normally. When I tried to go to factory mode via fastboot I ended up in endless bootloop. Back in TWRP I tried to restore my backed up ROM from before rooting, but nothing really changed. I am really desperate because I have not find any solutions for my model and I don't want to use other montana models stock ROMs as I suspect them not to be compatible. What shall I do?
Cheers

Flash montana_retcn stock rom via rsd lite or fastboot and your device will boot again but it will lose all your files

Thanks senor, but how do I flash it via fastboot? Can't I use TWRP instead?

Ok I was able the Stock rom, but it is Chinese, not the global one wihout Gapps and lots of bloatware. Do you know if there is also a GLOBAL stock ROM I can get? Conversely, is there perhaps a custom ROM like Lineage OS or others that is compatible with this device? Cheers

Sorry this is the stock rom of montana_retcn, to install the playstore by the store that comes in it, and it has the English language.
The rom that you were supposed to be a shop rom of the store that you bought, mine came with one of this but unfortunately I do not know where it has to download ...

Ok I guess there is nothing more to be done here. Any custom ROMs are also probably not lying around too I guess :/

Turn off the device, boot into Fastboot Flash Mode using vol down + power, using volume keys scroll and select factory mode and device will turn on. the next time you boot up the device, it won't go into TWRP directly. I have faced this issue many times. Hope this helps.

Not in this case. What Factory Mode did was that it got stuck in loading loop playing the Moto logo endlessly for over 5 minutes. Anyway, the phone is now hard bricked so I am facing even larger issue )

I'm having the same problem with my wifes g5s.
I have found that from twrp>restart>bootloader (phone then enters bootloader) I can the immediately choose "start" to boot the phone.
But that is a hassle I'd prefer my wife not having to go through...

Flash stock ROM via fastboot problem will be solved..
As far as people who need play store can flash gapps via TWRP as a same method we use for custom ROMs.
P.S. i will not suggest to buy XT1799-2 because this SKU is purely made for Chinese Market, if you need any custom ROM go to Weibo.com/diyroms and post a request to build a custom ROM for this device.
And there are some custom ROMs available that you can search via baidu.com ( Chinese Search Engine).
I will try to find any ROM and post for you guys and also post. Request to build for XT1799-2.
CHEERS

so have you find any global custom rom for this device ?

Question Poco f3 Error: Sending modem_ab

good evening
I have been trying to return to stock miui from Pixel Experience since yesterday but get this error every time I try to flash the Firmware and do not know what I can do about it. I would be happy if somebody knew what this error is from and what might fix it.

Same problem. Don't try more things because you will brick your phone like mine.

Thanks for your reply. What did you do that bricked your Phonem? This way I know what to avoid. Thanks you in advance

As you are sure your device is a eea one, try with this last official stable firmware : Version: V13.0.7.0.SKHEUXM
You can find it here https://new.c.mi.com/global/miuidownload/detail/device/1900394
Fastboot version here at bottom : https://xiaomifirmwareupdater.com/miui/alioth/stable/V13.0.7.0.SKHEUXM/
Or https://bigota.d.miui.com/V13.0.7.0...EUXM_20220627.0000.00_12.0_eea_e461331a7d.tgz

Thanks you so much I will try that

and i did not mention this but I started this whole project of returning to miui because my poco was and still is in a bootloop and is only accessible over fastboot, not recovery and even though it sometimes gets to the system it almost instantly crashes and reboots

Still the Same Error unfortunatelly

Ok,
Do you have any idea what you did that may have caused this bootloop ?
Have you used any Qualcomm Tools or any soft in EDL mode ?

No, I did not do anything that would mess with the system to my knowledge . which is why i really do not know what to do. Can This Error occur because of a USB 3.0 used to flash? The Phone even tries to reboot when it is detected as a Fastboot device, maybe This has Something to do with it. Maybe it loses the Connection and therefore the flashing process stops. Are there possible ways to fix This?

Try with the latest android platform tools.
Put the content of platform tools archive in the fastboot folder and launch flash_all.bat don't use flash_all_lock

Still the Same Error . Can This be because of a Driver or a hardware issue?

i had similar issues but with the super partition when trying to flash from cmd.
flashing with miflash instead solved it.

It doesnt seem to make any difference to the error whether i flash it via cmd or miflash

Maybe : So as you can try with other PC, USB cable, USB connector, reinstall USB drivers...

I already tried with two Notebooks, I will try again tomorrow with another PC and installing USB drivers again. Thank you

You could try redownloading the MIUI ROM... you got it from xiaomifirmwareupdater.com right?
And yes ^^, try other PCs/laptops and other USB-cables.
Just please make sure
Unfortunately, Fastboot-Flashing is a gamble. It's not a solid protocol. It has zero protection against sudden USB-connection loss.
And manufacturers like Xiaomi go out of their way and block Qualcomm's EDL Mode, which is the only way to recover your phone in case Fastboot Mode stops working, because that Mode itself can also get damaged.

Fixed - first flash a miui recovery rom from twrp make sure the rom version lower than the latest one, now flash and boot miui , now just update from miui updater once you updated to the latest version , now try to flash the fastboot rom that you trying to flash, it should work.

I cant access a bootloader like TWRP because the phone still keeps rebooting after a couple of seconds in the bootloader so i cant really do much. I only have access to fastboot

nockcx said:
just flash a custom vbmeta and then install a custom recovery in to the boot partition like fastboot flash boot ....flash both the slots boot_a and boot_b the run fastboot reboot recovery do all this with latest platform tools

okay Im as far as I have never been with a very weird method, maybe somebody can explain. Because my poco always wants to reboot I found out a way to keep in in Fastboot mode. I repeatedly press the power and volume down button, This way it stays on for a lot longer, but it still is not enough to succeed at flashing the rom. It also lets me believe that my problem is not a software but probably a hardware problem, otherwise and cannot explain this suuuper weird behavior. what do you guys think? is there a possible fix you know?

Question [lineageOS][Recovery]Stuck with fastboot bootloader bootloop

I had lineage19.1 working and a respective custom recovery with it. That was cool. Then I got dumb...
I proceeded to flash the new custom recovery for lineage-20.0-20230103-recovery-lemonadep.img. I am still not sure if the recovery needs updates or how to do so anyway. Can I still upgrade to version 20.0 with a recovery from 19.1? Regardless I am stuck in fastboot loop.
I am lost. I can't get to recovery mode anymore. How do I check things and see what to do next?

Hi.
I have been looking into lemonadep a bit lately.
I found a (renewed) 9 Pro a few days ago.
Should be here by the end of the week and I test more then. ​
Might want to ask your question in the LOS 20 thread.

I suppose you are about to flash lineage20,
if so, search "payload-dumper" tool
from the rom's payload.bin extract dtbo, vendor_boot and boot img files, flash them to the related partitions, and your phone should be ready to load the new rom via sideloading it

Thank you for your time and consideration.
I have lost track of my own efforts here. Basically I'm right where I left off, with a little less battery. I am now onto the process of using MSM tool from this place. I get things started and then I reach "param preload failed" under the status, in the MSM tool. Is there any hope? I get scared when reading this disclaimer...
"If you modified any partition not touched by MSM, namely param and persist but there are others, you face a possibility of a hard brick. MSM will reset your "Enable OEM Unlocking" in dev settings and you might get a corrupt boot. Restore your backups before attempting. That said, If all you just tried to convert a ROM using OTA payload.bin, you should be fine."
...because yea I'm a curious kitty. I think I was messing in just about everything dangerous that I could... I still have a bootloader screen, thats fun to play with... I've got the right driver from qualcomm and it says the proper "QDloader 9008." But still no dice with MSM.
Is MSM the only option? I found this other OEM reFlash tutorial. I have questions tho...
Step 4: Gives me a prompt that says "Server Busy" "This action cannot be completed because the other program is busy. Choose 'Switch To' to activate the busy program and correct the problem."
I'm gonna stop running through the dark and hope someone can be my savior. A wing and a prayer.

What phone you got tmo,global EU?

I always assumed it was the global version. Bought it in the USA. Model LE2125

Host Machine is a Legion 7 16ACHg6.
Perhaps "New generation USB 3.0/3.1 ports may not allow the QPST tool to recognize your phone and could also cause problems during the flashing process."
Q1. Would there be a way to test and verify this possibility with my current machine? I am using the factory "red" usb-c cable.
Q2. How to verify no other drivers are causing issues simultaneously. (I went through quite a number of drivers before this)
Alas, my previous question regarding this "alternative MSM tutorial" and what the Server Busy means, should take precedence I think.
I am new to XDA and the android community and I truly love and thank you all. There is so much here and so much more opportunity. Thanks again.

[SOLVED] boot loop after i tried to fix broken root

I tried for like 3 hours to find a boot.img and i had root on my phone, but without wifi and sound.
a quick google search showed me that it was because i had a wrong version of the boot.img, afterwards i found another one and now after i have tried installing twrp, booting and flashing using adb (stock and modified versions of boot.img) but it just keeps bootlooping. in twrp i cant wipe, make a backup, see any files in /storage/ and i have no clue what to do next.

What model 7T do you have? HD1907? What was the rom that you were using before you installed TWRP on? OOS12 does not support TWRP. Custom rom A13 does not support TWRP. Only a few custom rom A12 and OOS11 support TWRP.

Idk but I'm just wondering if flashing the last working rom image (dirty flash)? That would eliminate TWRP(?) and eliminate Magisk(?) while hopefully keeping the device from being wiped possibly?
*** Hopefully someone could/would verify this before you attempt... ***

i was on android 11 but i cant remember the version, i have HD1903 (EU ver). i THINK i had the one from the oneplus website(https://service.oneplus.com/us/search/search-detail?id=2096229) but idk anymore

I JUST RANDOMLY TRIED BOOTING MY PHONE AGAIN AND IT WORKED imma check if everything works and will regardless still look at this thread bc it can prob break easily

i cant find the file for my current version and it doesnt work if i try it with the only version that is android 11

and i cant turn my phone back on
and after i installed the drivers i had to restart my pc and now there is this thing at the bottom right:
testmode
windows 10 pro
...

i waited until my phone had no more battery charge and now im bootlooping again :/

nvm it just booted

im downgrading it now and i dont get the error "smth communication smth" in msmtool anymore
alr it worked my phone is wiped again but i can turn on wifi and sound
but how do i root my phone now? I have an Idea, im gonna write step by step what i think gets me a rooted phone please confirm if that would not break my phone ^^' (bootloader already unlocked)
1. enable usb debugging and allow my pc
2. download and install the latest magisk version from the github
3. download magisk patched boot.img for ver 11.0.5.1BA BUT since i cant find anything on the internet im gonna have to use the zip file from the unbrick tool thing (https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/EU_HD65BA/R/) and then patch the boot.img using magisk myself
4. then use platform tools and type following commands: "adb reboot fastboot", "fastboot flash boot {the patched boot image file}"
5. then use magisk to direct install the root thing

i just realisized the unbrick thing that i wanted to use instead of a boot.img doesnt have a boot.img in it... WHERE CAN I FIND A BOOT.IMG brooo androidfilehost.com doesnt have it the unbrick tool doesnt have it
omg i realized i could update my phone to 11.0.9.1 then download the same version from official website and use the dumper to get the boot.img **** meee

wait it sais its 11.0.9.1HD65 AA and not BA **** me

k nvm i just changed the site settings to germany and now its BA

i just went for it and now my phone is rooted thank you very much for your help i would've prob tried to revert back to stock for like 2 weeks and then cry that i cant root my phone thank you so much xd

Question POCO F3 gets stuck during flashing with MIUI 14 XIAOMI.EU

Hi all,
I hope someone will be able to guide me as how to recover from this.
So today I tried flashing my POCO F3 with MIUI 14 (xiaomi.eu_multi_HMK40_POCOF3_V14.0.4.0.TKHCNXM_v14-13) from the stock version MIUI 12.
I first successfuly unlocked the bootloader using MiUnlock. I then unlocked the developer options , usb unbugging etc. again on the fresh phone.
I also had USB / ADB and fastloader drivers installed.
I downloaded xiaomi.eu_multi_HMK40_POCOF3_V14.0.4.0.TKHCNXM_v14-13 , phone was already in fastboot and connected to the computer so run 'windows fastboot first install with data format' as an administrator which opened the cmd , after agreeing it started flashing the first few files successfully but when it gets to " Sending 'cmnlib64_ab' (504 KB) " the process just stopped there and it has been like this for around 30 mins - no error ...simply stuck on this step .....
I am not sure on what to do now to avoid bricking my phone, should I leave it connected ? Disconnect it and try flashing it again ? Download an older version of Xiaomi.Eu ROM (e.g MIUI 13 ) ?

Leave it connected for about 1 hour or so until you get success or error confirmation. If failed just reboot to system. If system failed to show up then go to fastboot again and install xiaomi.eu a12 version.
This is exactly why I hate fastboot method and always install rom from twrp

Flash 14.0.5 via orangefox recovery.

I left it overnight and nothing happened . I disconnected the phone and it rebooted ok. I am kind of worried about trying again. Is the twrp method safer ?

Just discovered that I stupidly set the "USB debugging (Security settings) on but I forgot to turn on "USB debugging" which is a few lines above in settings. Could that be what has stopped the process?

Phone should flash fine even if debugging is off. I would recommend you to make sure that the cable doesnt even move an inch during the whole flashing process as that sometimes interrupts it especially if you have a loose port.

I just switched the usb port from the back of the pc (which I think are USB 3.0) to the front panel of the PC (I suspect USB 2.0 ) and tried flashing the MIUI 14 from yesterday again - It worked !!!!

Hi...
Is it possible to flash a ROM that says "...V12.0.6....V12-10" for example, on a device that shipped with MIUI 11 Android 10, directly, without first updating the device to MIUI 12 normally?

you can do if you flash the fastboot version by mi flash tool, and your bootloader is unlocked.

Thanks... I really appreciate the early reply.
But can't I do this using the recovery method? And also must the android and miui versions of both the global stock rom and custom rom be the same?
Nevermind...thanks for your help

if you want to flash specific version of android, then you need unlocked bootloader and mi flash tool, otherwise make updater app do its job. and no need for the global stock rom and custom rom be the same. just put in your mind to backup your data .
