#1

so ive made a device tree using aospdtgen, and changing things as needed, im building fine, but when it come to flashing. it flashes !! but when i go to boot into TWRP.. ill explain process

First it boots normal process of bootscreen/unlocked lock flag notice, then the backscreen will light up as if about to boot into TWP but it doesnt it just siply stays on bootscreen, but enters adb recovery in which doing some debugging is showing its on twrp build, but TWRP is not starting ?

this is my BoardConfig:

Any Help is GREATLY APPRECIATED.. I've been trying to debug this issue for a solid week maybe 2 weeks longer now!!

(27-03-2025, 05:35 PM)xXHenneBXx so ive made a device tree using aospdtgen, and changing things as needed, ...

What manual changes did you make to the device tree after it was generated?

other than some of the additional lines and changing it to build for vendor_boot move the recovery resources over in the above for my board config.. ive changed the fstab made a twrp.flags .. eveything is copied over form device.mk like uevent files, also in the device make also inherit a couple other things needed for my device such as virtual/ab compression, gsi keys ( maybe not needed ) ..

in my twrp_{device}.mk ive inherited the vendor/twrp/config/common.mk and changed product name as twrp_{device}..

ive edited all the prop files adjusted and removed all unnecssary lines keeping only whats needed for recovery

inside my device dir i have the recovery/root folder with other folder files such as ... vendor/firmware lib/modules system/etc/ with ld.config.txt recovery.fstab(device original) ueventd.rc and i have the first_stage_ramdisk/fstab.*(s)

so far thats what i got .. if you need me to post any of them for reference let me know ill post them .. dont see what else im missing.. i did recently change and remove some of the module being loaded, and directly have just spd-drm.ko by kernel and remaining being loaded by.. ive changed my modules.load.recovery for only recovery modules commenting out the rest ..

now i get i a bootloop ?

Dump the full firmware free on tadiphone dump and drop link
Because u can't have a stable twrp with such tree

Full Firmware Dump of The device is also on My Github page link here : Umidigi Full Firmware Dump

Used Dumpyara for firmware dump

I had used the firmware dump that i had made with dumpyara stated above in link, and made a device tree from the firmware dump using aospdtgen, and changing anything needed for twrp variation, editing prop files, *.mk files etc.. what is it from the firmware dump that i need ?

Your ramdisk in found inside vendorboot so use vendorboot.img to create a tree
