Troubleshooting qin f25 bootloop

urgent!

i did soothing terribly stupid right after waking up without thinking. long story short i need desperately the dialer app from the qin f25. Please pull and post if you have this phone

typed with dpad from my sonim (:cry: bad old days)

Donโ€™t you have a full backup?

Get it from there.

I wish i hadโ€ฆ

Using stock?
If Google just install anyone and update.

Sonim XP5800 has the best T9, donโ€™t know why your saying its bad

And what do you normally type on? The dialer app was the only way for you to get to the JTech app?? :laughing:

I donโ€™t have any qin phones, but I do have the dialer/phone app apk from the CAT S22

Download link here

No. I usually type from gboard on a qin f25 that isnโ€™t bootloopingโ€ฆ

installing any dialer other than stock will probably bootloop for the same reason itโ€™s currently doing so.

btw iโ€™m using tt9

Worth a tryโ€ฆ

On the XP5800? That one is able to type โ€œIโ€™mโ€ and has lots of emojis, so no reason for tt9 reallyโ€ฆ

Complicated. Got used to it cuz itโ€™s the only one that works in termux. And on one of my xp5800s the right dpad button doesnโ€™t work so canโ€™t scroll through options so i made down be to go to next option in tt9. Whatever.

anywayโ€ฆ i guess iโ€™ll try.

did it work for you? What did @10110000 bring you?

Yea I donโ€™t think thats my usernameโ€ฆ

on mitmachim.

Didnโ€™t try yet cuz i highly doubt it would work. Maybe iโ€™ll try soon. itโ€™s not just like opening a file manager and replacing. Meanwhile i tried a lot of easy stuff and all failed including flashing from zip (requires signed zip). Will probably have to read with mtk and mount and change the apk and repack and flash

I never used twrp. I wanna boot twrp from fastboot. All I need is unauthorized adb access. Android 14 mt6768 kernel 5.10. Wonโ€™t be flashing twrp so doesnโ€™t have to be for sure compatible.

Anyone here know where I can find generic twrp that work across different devices and might work on this phone? twrp.me?

Another question, is there any chance that flashing system_ext from stock can make booting issues if the firmware I have is highly modified? @ars18

Didnโ€™t you get along with that dialer? Donโ€™t you have MT manger?

Not sure if you realize the situation. The phone doesnโ€™t turn on at all. Having the app helps if I can get adb which I canโ€™t. Iโ€™ll have to get adb via twrp or flash possibly incompatible system_ext or extract system_ext from my phone with mtkclient with a computer which I donโ€™t have now.

(Iโ€™m writing in Hebrew because itโ€™s only for you, if itโ€™s problematic Iโ€™ll delete it) I got confused because you wrote in the interns โ€œfor whitenessโ€ they usually say that he entered the barik

I decided Iโ€™ll summarize my situation.

device hardware:

  • qin f25
  • Android 14
  • kernel 5.10
  • chipset mt6768

software:

heavily modified! Dayan tikshoret added many system apps including google play and much more. Rooted, vbmeta patched, writing to /system doesnโ€™t cause issues, Magisk + lsposed + core patch (signature spoofing)

the stupidity I did

i took a modified Google dialer (phone) app meant for qin f21 (android 11) and replaced my dialer app in system_ext/priv-app with that one - yeah I know really stupid. Was tiredโ€ฆ I didnโ€™t backup anything at all

outcome of stupidity

the phone boots till the last loading screen (part2 in bootanimation that goes again and again till ready to boot), loads for really long till it reboots to the recovery that says Iโ€™ll have to factory reset with 2 options: try again an factory data reset.

why and how to fix

this section is just my assumptions.
I doubt itโ€™s signature stuff Cuz I messed with different system apps with no issue. Probably just oat not compatibl or just the app itself not being compatibl and the system checks some basics about system apps before finishing boot.

So I basically have to get back the old app there. How? Thatโ€™s the work

what I tried

  1. I tried adb while booting and in that recovery screen and in both, adb works but my host is unauthorized. Tried patching boot.img by injecting my adb keys + setting secure to 0 but still showed unauthorized.
  2. Mtkclient: need a laptop for that. Donโ€™t have 1 now. (not working in Termux - dependency issues)
  3. twrp I donโ€™t have 1 that can work on my phone.

notes

I checked on an Mitmachim since this is a popular phone in israel and doesnโ€™t work at all in the USA to see if someone can share firmware. Someone sent me the app.

on the forums thereโ€™s a link to download the full stock firmware. Iโ€™d do that if I knew flashing stock system_ext on a device thatโ€™s highly modified wonโ€™t make issues.

Any tips, ideas etc is appreciated.

Whoever gave you mitmachim Itโ€™s not just anyone, itโ€™s whoever created this rum.

Why donโ€™t you pull the apk from the rom?
