What I believe he means he was upgrading to IPL/SPL 2.26 by flashing T-mobile,after downgrading to 1.xx by Button's Rom,while flashing,it got interrupted and in panic he reset the device,now can't power Up the device.

Well,interrupted during flash or resetting doesn't brick a phone.

secondly,Bootloaders IPL/SPL are automatically downgraded/upgraded by flashing a Rom with IPL/SPL when flashed.

Unless,as I posted above, if he has flashed G4 IPL/SPL or a G4 Rom with IPL/SPL,it wud certainly brick a G3 device.But as he said he was upgrading to 2.26,means,he was flashing T-mobile,so I believe,it cannot be bricked this way :)
[8125, K-JAM, P4300, MDA Vario Software Upgrading] zabardast_1:
OOOPS!

On second thought,did he mention its a G3,well,what if its a G4!!!

and he flashed Button's Rom............. GONER!

I assumed its a G3,coz he posted ipl/spl 1.xx and 2.26 and he already got it upgraded.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] s_v_r:
hi thanks for all the info.

Before the upgrade I verified it have more than 60% battery (arround 80%). I had got a new battery and charged it 100% overnight before i tried the first upgrade.

Its a G3 phone (It showed 2.2x a did not have following .000 which show for G4).

I had downgraded using the Button ROM and was upgrading the rom using WST write ROM.

So is there still a chance..

I can try and see if anyone's got a HTC Wizard within my friends/around and try to charge the battery in their phone....just to make sure its fully charged

I have repair my wizard with this manual.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] gizmofan777:
I wonderfully and utterly stupidly did exactly that !!! I wrote a G4 rom on G3 Wizard !! It turned on once after the procedure and wm6 loaded all the "extras" and then re-booted... into complete darkness !! Now it's completely dead nothing turns on, not even the green charging light. I left it for a couple of months and the red light come on briefly... but that's all. Now it stops the papers from flying off my desk .... it's my funeral and I'll cry if I want to (:(
[8125, K-JAM, P4300, MDA Vario Software Upgrading] zabardast_1:
I honestly feel sry for it,but may I ask which was the rom which you say is G4,which you flashed ? coz all official roms are suitable to flash to both devices and custom build roms do not contain IPL/SPL in them,which cud harm any device,its really questionable as which was this rom which bricked a G3 phone,if you are sure your phone is a G3. YES! its certain that if a G4 phone is flashed with a G3 specific rom,it'll get bricked,was your G3 or G4 ?
[8125, K-JAM, P4300, MDA Vario Software Upgrading] gizmofan777:
I confirm my Wizard is a G3 device and the rom I accidentally wrote over it was a G4 rom (I since deleted it from my computer to ensure I would not repeat the mistake) ....
[8125, K-JAM, P4300, MDA Vario Software Upgrading] ashasaur:
So, there are G4 specific ROMs floating around out there? Now that doesnt make a whole lotta sense. I thought that all carrier ROMs where G3 (and to an extent G4 safe), and that all cooked ROMs where G3 and G4 safe because they dont contain IPL/SPL?
[8125, K-JAM, P4300, MDA Vario Software Upgrading] mestrini:
After G4 came out, the providers started releasing ROM packages with two bootloaders and a new RUU that would detect the device DOC generation and flash accordingly. If you extract an 'official' ROM you'll find IPL_1, SPL_1, IPL_2, SPL_2, etc... which means G3 and G4 respectively and therefore safe to flash to any Wizard in the market (minding the CID status of course)

As for G4 only roms i believe that might be a few around that were cooked in a time when the "G4 safe" concept wasn't yet implemented and when one would flash a complete ROM and upgrade IPL/SPL at the same time.

Nowadays, since Wizard official development has ended, almost everyone has a 'high' bootloader and only needs to change the OS version/flavor thus the absence of IPL/SPL in a released cooked ROM

Hope it's clear :)

I bricked my phone too!

Hi there! I think I have the same problem. My phone is a G4 and it won't boot to bootloader mode nor charge in a wall charger. I had my phone unloacked and during the process, my phone shut down. Now it's dead. Is there a go around for this problem? Thanks.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] centuryheli:
Hey Guys,

I've got a similar thing, think I might have flashed a G4 file to a G3 Wizard.

I have, by following through the "Let's Revive A Wizard" thread (http://xdaforums.com/showthread.php?t=274766) been able to get the thing to boot into the bootloader screen and show IPL 1.05 : SPL 2.26.clip I think from memory and then flashed the 02 ROM but then it just boots back to the bootloader.

I also tried an SD backup from my other G3 and followed that through but nothing.

I think there is a way to revive using the methods shown, but there appears to be no more help relating to it and I'm out of ideas myself.

If anyone has a IPL & SPL file for 2.26 can they post it for me to try.

Thanks.

Ian

I've taken my sim card from my old Razr and put it in my new tilt. Everything seems to be working fine. I had unlimited MediaNet data on my Razr. Will that carry thru to my new Tilt?
[Tilt, TyTN II, MDA Vario III General] Cosmic Blue:
yes, it will carry through until AT & T realize you have a WM phone then they may make changes to your plan.
[Tilt, TyTN II, MDA Vario III General] mikemorris:
i had the same thing i went into the store and asked and all the did was register my phone with the SIM/phone # with the IMEI # the guy said this will keep people from stealing it and putting a new SIM in. but in all reality there isn't a reason to go in and do anything the plan is identical UNLESS! you add MS Exchange, then they tack on an extra $10 or maybe $20 i would have to check. I don't recommend it just hook up your gmail account.
[Tilt, TyTN II, MDA Vario III General] Hyden121:
I would just keep the sim int he new device and not say anything about it. Let ATT figure it out. I seriously doubt they will though since they have warranty swaped and upgraded my phones in the past and everytime I call they still think I have my original from when I first started...
[Tilt, TyTN II, MDA Vario III General] amkaos:
is that yer best guess?... cuz it is ONLY a guess, just to post something.

att aint gonna do nothing.. not a thing..

you learned something today..

at least when you post guesses, you should preface it as a guess.
[Tilt, TyTN II, MDA Vario III General] mikemorris:
hope my reply helped 2 seperate plans unlimited (which you have) and the Exchange server (allows sync with windows exchange, outlook etc.)
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
It's not a guess but a fact as I had the 20$ unlimited media package from my razr, then to my Hermes, then to my kaiser, and all was well until my Kaiser crapped out and had to upgrade to the ppc plan to get my new kaiser running. 35$!! They say that data plan doesn't work for ppc's, even though It was working just fine for two and a half years; I smell a lawsuit coming...
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
I'm not sure why nobody has looked into this with their local attorney's or even at a Federal level, these phone company's are getting away with anything they wish! I don't even pay half that amount for my monthly DSL! **** this ****, goin to downtown L.A. today to connect with my Lawyers
[Tilt, TyTN II, MDA Vario III General] kilrah:
@kaalgoosy: Read this.
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
Point is, you shouldn't have to run circles and basically trick your service provider from charging you more monthly charges when it's not necessary for getting the same service. Multiply the added service charge by how many new customers are being duped=$$$$$$$$$$$$$$
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
Yea, there's a way to sneak past these charges by pretending to own an old school miami vice brick phone; but how many other people are getting screwed???
[Tilt, TyTN II, MDA Vario III General] kilrah:
The point is, the plans are pretty unclear now as both are "unlimited". But the cheaper one is to be understood as having lets say a 3GB/month limit before they will come and moan at you because there's no way you'd download that amount of data using a common phone and light browser, while with the expensive one you can do what you want (truly unlimited).

The only thing you would get from suing them is for them to state a clear transfer limit for the cheap plan. The thing is that, but if they have too much trouble they'll just limit the cheap one at lets say 2GB/month.

Or you wouldn't get anywhere as I wouldn't be surprised if there was already a limit mentioned somewhere in the small print that nobody reads.
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
No, Both plans are labelled and listed as "unlimited" media packages, and I've experienced no extra charges from extra kb or mb downloads for the last two years
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
there was never a specification on download kb's. It was an all you can eat plan, I must have spent an hour on the phone making sure I wouldn't be charged for exceeding my download limit as I 've seen my friends phone bill exceed 1000$ in one month for sending one too many pics and texts
[Tilt, TyTN II, MDA Vario III General] kilrah:
That's the point. They don't have a fixed transfer amount after which they charge you for extra traffic, rather if they judge you use too much with regard to the device category your plan is meant for they'll "kindly force" you to change for the one that matches the usage you really make of it.
[Tilt, TyTN II, MDA Vario III General] kaalgoosy:
That's exactly what I'm talking about, a contract is a contract, and you can't just change a stipulation or add a ghost policy because it might not suit your company's best interests. Only in my second year of law school, but c'mon, this smells like horse****, gonna read the finer details today

For the global, we don't know until we get it, but [MENTION=10284123]Some_Ghost[/MENTION] checked with the euro and signal stays, so you can do the euro version instead of the global and still keep the the signal without reflashing your modem.

---------- Post added at 02:38 AM ---------- Previous post was at 02:32 AM ----------

If you flash your modem backup with Euro firm it sticks throughout updates so far... It didn't work for me on global. You still need to restore your modem backup on either firmwares. Global so far modem doesn't stick after updates, euro so far, it stays after updates.
[OnePlus 8 Guides, News, & Discussion] ecompton59:
I fixed it with ota if you flash global do the enable and and dev settings I waited to install magisk. Ayer first boot put ota for global and it works because ota has modem in it and fastboot can't flash modem yet with bat file but I have no issues I have global modem and global ROM and from here on ota will work no need for modem
[OnePlus 8 Guides, News, & Discussion] Vio281:
not really converting to Global then? this is just so you can use dev ROM, but since DEV rom hasnt come about there really is no reason to do this.
[OnePlus 8 Guides, News, & Discussion] joemossjr:
What? He used global ROM. Not a DEV ROM.
[OnePlus 8 Guides, News, & Discussion] Some_Ghost:
I will try this thanks ??
[OnePlus 8 Guides, News, & Discussion] rjp0615:
Does the Global ROM share the same 5G compatibility introduced in the new TMO ROM?
[OnePlus 8 Guides, News, & Discussion] Vio281:
Thats what I'm saying, this is to flash rom, it not necessarily converting the phone to a global phone since it still need Tmobile Modem bin file in order to be function as a phone. If you take the phone outside the U.S it questionable if it works, that is why I say this is only for Dev Rom and in this case stock global rom but it is not a global phone.
[OnePlus 8 Guides, News, & Discussion] UniX1rm:
[MENTION=3659125]joemossjr[/MENTION] :p :p :p

Well check [MENTION=6315182]ecompton59[/MENTION] 's response. He was able to get things working.

The modem does work, just there is an issue with the fastboot flashing the modems. The TWRP restore of the modem is to get cell signal right away.

Here is what I did:

After I did what is in the first post in the thread:

I used oxygen updater to download the EU update and flashed it via "Local Upgrade" [MENTION=10284123]Some_Ghost[/MENTION] tested that as well.

There is signal. I believe that it may have flashed the modem "maybe", unlike fastboot.

While I was on the EU version, I downloaded the update for the global, and did a "Local Upgrade" again, and got signal.

I did all of this with Magisk being installed and after each "local upgrade, before reboot" I install Magisk on the "inactive slot, ota".

Technically speaking and don't quote me 100%, the first flash to the global is what gives issues with the sim, but that's the way to get the ability to do "local upgrade" because it is disabled on the t-mobile firmware.

Theoretically and I haven't tested.

Unlock bootloader >> Flash global "won't flash everything properly" = no signal

Global to another global or EU update >> will flash the modem >> signal will work "as it will properly flash everything"
[OnePlus 8 Guides, News, & Discussion] Vio281:
again, this does not make it a global sim unlock phone, you are flashing a previous Tmobile Modem on top of a Global rom.
[OnePlus 8 Guides, News, & Discussion] UniX1rm:
It at least we can run different firmwares on T-Mobile. You could try the global msm on T-Mobile and report back. As being sim unlocked depends on the bands enabled in other countries but should work with any sim.
[OnePlus 8 Guides, News, & Discussion] bluemoel:
is there different functionality between the tmobile modem and global modem firmware? I flashed the global rom and am using that with tmobile modem flashed through twrp. I haven't done a local update yet to get the global modem. if I do, what is the difference running that vs the tmobile modem? im in seattle using tmobile anyway.... would I see a difference in anything? speed? I had updated to the tmobile ota right before I flashed, they supposedly updated something with the modem in that update. im just wondering if there is a benefit to using the global modem or not. I definitely see the benefit in using he global rom though....lol
[OnePlus 8 Guides, News, & Discussion] Some_Ghost:
you'll be fine, my signal hasn't changed since flashing it remained the same as far as I can tell

---------- Post added at 12:34 PM ---------- Previous post was at 12:30 PM ----------

Be happy that people actually take the time to experiment and work on things like this for the community so we can root and run different firmwares, kernels, and recoveries etc. At the least we aren't stuck on TMO firmware with lack of updates and missing features and as far as we can tell everything is working and odds are you aren't going to be using a T-Mobile SIM when going out of country anyway. Any issues will be ironed out when we cross that path I am sure ??
[OnePlus 8 Guides, News, & Discussion] Jacob O Link:
so did i, tbh the op should prob update his instructions but more importantly provide details about he FP sensor. I read op over and over and it mentioned nothing until you click "Old instructions" sucks tbh. However i did flash this twice and convert to global twice, all you have to do is msm back to stock, update from stock to latest version, then you unlock bootloader and flash the oxygen os rom, i used the 10.5.7 version and updated OS when i installed that, i had signal and everything was fine imo except the FP sensor.

[OnePlus 8 Guides, News, & Discussion] zander21510:
This is how you do it successfully, even the comments in this thread are unclear, and a few update steps are unnecessary. Here are the steps with helpful links:

1. No matter what firmware you're on, MSM to 10.5.7 using the method in this thread.

2. Unlock bootloader using the method on the oneplus website here. You'll have to repeat the process even if you already unlocked your bootloader after the MSM process (but you can reuse the unlock token so you don't need to wait).

3. Download the latest global file from the link in this thread (the latest as I wrote this was 10.5.10-GLOBAL)

4. Reboot into fastboot on your phone

5. Double click flash-all.bat in the extracted folder

That's it, when it finishes and reboots you can check if you were successful by the signal. If you failed, just start over.

I backed it up before it broke, and tried restoring it, it didn't fix it. I also noticed my persist.img is twice as big as it was before it broke itself. Old one was 16kb, broke, now its 32kb.
[OnePlus 8 Guides, News, & Discussion] MNBatman080715:
If it fails then you are not in fastboot d which looks like the recovery home page with the OnePlus logo and three languages on it. If the flash-all fails more than likely you are trying to flash it from bootloader, which is not the same as fastboot anymore ??
[OnePlus 8 Guides, News, & Discussion] esjames:
Ok good, what I ended up doing is coping the persist image (my original) into the folder of my downloaded fastboot rom (global) and edited the flash-all bat to include fastboot flash persist persist.img in it. After it was done my FP worked like it should. Pretty easy.

You may not have to. That is just what I had to do to get the msm tool to work. The persist keeps sensitive data about the FP sensor and if you do not have a working backup you may lose fingerprint for good, there a guide to fix a broken one. OP updated his guide on this thread thankfully.
