In the last part to flash a full OTA ROM of any region, can I flash OOS 11 or I have to flash OOS 10 OTA to match the same Android version? You can flash any Full OTA ROM after flashing Fastboot ROM. So you can stay on OOS 10 or OOS 11 if you'd like.

Which guide did you use to install TWRP? I wanted to do a backup of persist and modem/efs image files. From what I remember backing stuff like persist, I used MSM Tool. I tried to find the YT video that shows a guy backing up persist and modem using MSM Tool but I couldn't find it. Anyways, from my current knowledge, you back up persist, etc. either through Root and/or Command Prompt/CMD or MSM Tool. From what I have read on others' experience, most commonly I read people backing up through Root Method.

The Pixel 7 is a great phone. My friend have it and he love it. Everything just work, no worry about bloatware or slow downs. I hated the battery life on the first day, only lasted 4hr SOT. I figured that Stock Launcher was eating up all the battery, I tried to ask others if they have a similar experience but last time I checked, I was the only one who had stock launcher consuming the most battery usage: went up to 40%, higher than my social media apps.

The fix is to change launchers, I recommend using Lawnchair and that has given more 7hrs+ SOT, so if your friend is having major battery drains on the Pixel 7, I recommend him switching launchers.

Not sure if you know this. Be warn!! If you RMA to replace your phone, Google will give a new phone where the bootloader cannot be unlock. And there is anything they can do. Unless you want to file a suit. I have a friend who did a RMA replacement and was not able to unlock bootloader anymore. DAMN. Thanks for letting me know in advance, I'll try not to RMA it, after all I cannot unlock bootloader yet and I won't be planning to in a while.

Which state you from? I'm from CA here. Originally from the Philippines but currently in FLAAWWWRIDA, about to graduate high school on my last upcoming school year and currently a dual enrollment student
[OnePlus 8 Guides, News, & Discussion] magi44ken:
That's why my friend's Pixel 7 have a great battery life compare to other users. He immediately replaced the default launcher with Nova Launcher that he love.

I love the state of FL. It always have the beautiful warm weather there. Specially the great beaches you guys got there.

Nice... I bet you can't wait to get to college. You can set your schedules. One of my cousin gets graduated from high school.

I think I screw up big time.

When I try to flash the EU firmware, I get stuck flashing the system partition with this error message.

Invalid sparse file format at header magic
Sending sparse 'system_a' 1/4 (523320 KB) FAILED (Write to device failed (Invalid argument))
fastboot: error: Command failed

I finally realize that I forgot to set the target to TMO in MSM tool when flashing the TMO MSM firmware.

Now it bootloop in the fastboot mode and can also access the Recovery Mode. I can't only turn off the phone manually using Power and Volume Up buttons combo.

The really bad bad news is I can't seem to boot to EDL using the Volume Up and Down buttons. Doesn't matter how I try. I also tried the holding Volume Up, Volume Down, and Power but that always trigger it to boot to fastboot mode.

I can't install or boot directly from a recovery image like TWRP or OrangeFox. It say missing boot partitions.

I google search and find some people did the same mistakes like me and they were able to boot to EDL mode somehow.

Do you have any tips to boot to EDL mode?
[OnePlus 8 Guides, News, & Discussion] thattechguy_69:
Do you have any tips to boot to EDL mode? In fastboot mode "START" screen, you can use your volume buttons to change the "START" to "REBOOT EDL" and that should do it.

I love the state of FL. It always have the beautiful warm weather there. Specially the great beaches you guys got there. FL is nice, but weird weather. Just had a thunderstorm before work at 6am to 9am and the soon I arrived at work, it immediately became sunny and dried up already. FL has some of the weirdest weather patterns ever!

Nice... I bet you can't wait to get to college. You can set your schedules. One of my cousin gets graduated from high school. Nah, I regret not preparing sooner before I graduate, tbh, I don't wanna graduate yet. I am heading to the military after I get my BA and I am also planning on getting a scholarship to pay my BA. I already went to MEPS so hopefully God's got my back.
[OnePlus 8 Guides, News, & Discussion] magi44ken:
Finally got it to boot to EDL mode by using a different USB cable instead of the OnePlus red USB cable. This is so strange.

I don't have reboot to EDL option in the fastboot mode. I have to use Volume Up and Down combo method.

The reason that I was not able to boot EDL mode because of the USB cable. For some strange reason, my OnePlus USB cable doesn't work. I tried three other USB cables that I have and only two of them work with EDL mode.

I really admire what you have planned for your college. I wish best of luck to you.

You should check the ACC magisk module that you can setup to enable battery idle mode that can prolong the battery life of the Pixel 7.

Getting OTA update did not help or fix on Global...at least not for me. I have just gone through both versions, Global and Europe... neither has worked after restoring my original modem. What a waste of time... been working on this all day. If anyone can tell me the secret or another way to restore the modem, I would surely appreciate as TWRP is either not restoring it or is restoring it but it is not taking. TIA

Edit: Well, MSM and full restore to original, or so I thought. Tried to update from 10.5.7 to 10.5.8 and got errors, eventually ran MSM again. This time updated fine to 10.5.8 (Tmo) was going to unlock bootloader, root and TWRP again, but now I have no fingerprint or facelock, only pin. So whoever thought MSM was going to give you a completely brand new phone, well, apparently not. I am bootloader locked again, no root, no twrp. But also, no fingerprint or facelock. Any ideas? Any help would be appreciated. And one other thought, I never could get the modem to restore on Global or Europe. But I am wondering if a real modem backup and restore involves a "non-hlos modem.bin as I have ran into this but didn't get that far or even know who to pull it. Again, any thoughts on any of this? These phones are too expensive to mess up.

After further research it states using the MSM tool to unbrick or go back to an earlier OS version, that it is possible to get errors when trying to get FP going again, so, I did back up my persist, but how do I restore it?

fastboot will not allow to flash to critical partitions... :( What about twrp? Can flash it there? This has jacked up my phone and it is not functioning properly... need to fix it. Any help would be appreciated. Oneplus support asked me to do a hard reset, I did, it didn't work. Now they want me to send it in for repair. Seems someone on XDA has a solution, but MSM is not it. I tried it 4 times now, it does not fix the persist partition, even tho it should.
[OnePlus 8 Guides, News, & Discussion] LLStarks:
MSM will not repair persist. Not sure if you have to flash persist from bootloader or fastbootd but you should have be able to flash it if your bootloader is unlocked. If you did an MSM, you have to unlock again.

open a terminal emulator with root

[OnePlus 8 Guides, News, & Discussion] free4flight:
Yes just got the same advice over on another forum, must be good advise... doin it now. Thanks:)

Edit: Well, tried it both ways, he wrote his a little different and it copied the persist but didn't help me. Still have no FP or Facelock, and intermittent loss of signal and wifi. Seems I'm screwed. Never had this problem converting over to global on my 6T. The 8 is a *****, plus now my laptop is seeing my phone as a OP 8 Pro and it is not the Pro version. Any ideas?
[OnePlus 8 Guides, News, & Discussion] The_Anomalist:
First could you link that persist IMG? Also I believe it shows up as op8 pro because of the twrp recovery. Mine says it as well but the actually model in settings is correct. I also didn't have this issue on my 6t, it was super easy, right not I can't even flash on critical for some reason. I might have idea for persist issue as well

Looked into it more and it looks like if i try to flash that img it could cause way more issues. Unless it has changed since then
[OnePlus 8 Guides, News, & Discussion] Some_Ghost:
MSM relocks your bootloader, you need to unlock bootloader, reboot to fastbootd and then fastboot flash persist persistfilename. Using MSM after a conversion to go back to tmobile will always mess up persist that is why it is said in the original post to save it. Also before you convert you need to be on the latest T-Mobile update and you need to flash the latest global fastboot ROM or Europe. This is why people run into errors They Flash older fastboot ROMs you need to be on the latest update and convert to the latest fastboot ROM available.
[OnePlus 8 Guides, News, & Discussion] free4flight:
Yes, this I know, the problem is, I cannot get it to boot back into the system, it is stuck at the qualcom crashdump, therefore, I cannot get to dev settings to click on the oem unlocking or the usb debugging. I was hoping maybe one of these "one-step" root proggies would get in there but I haven't found a way to do it yet. I am screwed and will probably have to send it to OP for fix unless someone can help. The unbrick program won't even work, I mean it works, but afterwards it won't boot into the system, just back to crashdump. It is a ***** going without a phone.

Globals dats speeds are lagging

Since I converted to the global firmware i have seen a huge decrease in my data speeds at home (the only place I've been since the firmware conversion)

T-mobiles 10.5.8 OOS was definitely optimized for the t-mobile network, considering flashing back because i was getting a pretty decent 5g speed at home and now i am getting just lousy HSDPA+.

I didnt think there would be such a huge gap distance between the signal strength considering Re-flashing the T-Mobile modem was required to get service.

honestly its almost a complete deal breaker as i dont want to be on a snail speed signal.

Anybody have any ideas for optimizing signal strength?
[OnePlus 8 Guides, News, & Discussion] garz:
I am going to be flashing this weekend to global. Or was going to... I'll take some speed tests at work and at home and then try it again when I flash over to global.

Sad part is that, once your unlocked you'll loose the ability to get T-mobile updates. Unless someone will port them over for local updating through twrp.

I'm about to get my OnePlus 8 TMobile version tomorrow( took advantage of the free line plus half off the device). I have a couple of questions as it seems the process to convert has changed since the 6T:

Are people having success with the conversion to global ROM? Seems like lots of modem issues in this thread.

Once converted, can we update via ota or will it need to be manually?

Lastly, can we run custom ROMs based on the global version, after conversion?

Thanks in advance.

Can you relock bootloader and run stock recovery after converting to global version?
[OnePlus 8 Guides, News, & Discussion] XD-MOD2-9MM:
After reading the complete thread, I've come to the conclusion that I need to flash the flashall, then relock the bootloader, then run the MSM tool to ensure the modem is working correctly? Or do I unlock the bootloader again after I flash the MSM tool, and flash the T-Mobile modem? Nothing is 100% clear here lol. I did convert my 7T to international so I'm not clueless. Thanks
[OnePlus 8 Guides, News, & Discussion] gerguter:
No. You don't need to relock the bootloader. Make sure your up to date on Tmobile. Unlock the bootloader. Reboot to bootloader. Run the flash all from the ROM you downloaded. This will get you to global. Most of the time there is no need to flash the Tmobile modem. Once you are converted to global, update and you should have a working modem.
[OnePlus 8 Guides, News, & Discussion] parsa5:
Can you relock bootloader after this?

I'm not sure. You would still be running stock recovery unless you install TWRP.

I tried converting from TMO 10.5.10 to GLOBAL 10.5.7 but received some nasty "Flashing not allowed to critical partition" and failed to proper update. The phone ended up rebooting but network services was disabled. I restored a TMO TWRP backup and all if fine now but I still want to convert it to GLOBAL Variant for updates. My question to get this converted are.

1. Can I directly go from TMO 10.5.10 to the GLOBAL 10.5.7 or do I have to use MSM tool to downgrade my TMO software before I can convert to Global variant.

2. After I unziped and ran ./flash-all.bat things ran smoothly until the point the device was "rebooting into fastboot" at this point my OP8 boot into recovery. From there I manually got into fastboot but began to see the same "Flashing not allowed to critical partition error", no partition found, and some other random errors in power shell as the .bat script attempted to finish the install. Did I do something wrong to botch it?

Any help is appreciated. Thanks.

Can you clarify some thing."Reboot to bootloader and then ADB reboot fastboot". I'm long pressing power button, selecting bootloader as what I want to enter. From there I'm taken the screen that shows Fastboot Mode, PRODUCT_NAME, VARIANT, BOOTLOADER VERSION, BASEBANDVERSION, ECT. I thought this was the fastbott location I would run the "flash-all.bat" but it sounds like you said I need to run "ADB reboot fastboot" from here? I tried running it but receive a devices not found. I attached a generic image of where I'm running flash all from.

Also to clarify my self earlier. When I flash-all from the bootloader (that I attached a picture) the flash-all scripts gets stuck at rebooting into device and my phone rebooted into OEM OP Recovery for some reason even though I have TWRP installed.
[OnePlus 8 Guides, News, & Discussion] XD-MOD2-9MM:
Then you don't have the correct drivers installed. if you followed my instructions you should be out of screen that looks like the recovery menu which has English and a couple other languages I can't understand right there to choose from. That is fast boot d or whatever they call it now. If your phone is not recognized there than you do not have the correct drivers installed. The flash all can't be flashed from the bootloader screen that is not fastboot and therefore nothing will successfully flash. Good luck ??

Again that is not OEM recovery that is the fastboot d that you need to be in
