You can't downgrade/upgrade from smart 1.5. It's locked as in you can't changed the ROM. Kaya kailangan mo munang palitan yung bootloader mo to make that work. Nangyari na sakin before na hanggang canary screen lang ako with bootloader 1.04. I tried orange, smart 1.37 ayaw nang mag install. What I did was borrow a phone from an officemate, copy the bootloader 0.98 to my sd card using USB term, then flash that ROM to my phone. Tapos run ko ulit yung smart 1.37. Voila, may phone's alive again.  

Oo nga eh... yun na nga ang nangyari sa akin....  kelangan ko talaga munang mag chang ng bootloader...

SPV, pwede rin ba kung 0.99?

[spv_dman]

Just remember these when playing around with bootloaders:

1. version 1.04 - This SIM Locks your phone (for those previously unlocked) and prevents any ROM update even smart 1.37 won't work.

2. version 0.99 - Enables your phone to be downgraded / upgraded using any kind of ROM.  However, you won't be able to unlock a simlocked phone as the spv unlock software won't work.

3. version 0.98 and lower - Enables your phone to be downgraded / upgraded using any kind of ROM and SPV unlock is fully functional.

Yes you need a SD/MMC - card reader/writer to write the bootloader to your SD/MMC card, WinHEX is a program that let you read/copy/edit/write HEX files  :idea:

anyone here have a copy of the bootloader in their PC? I will use this kind of copying, from PC using winhex to SD. Please PM me if you have the file.

NICE TO KNOW.

Isa sa mga Disk Tools ng WinHEX kasi is "Clone Disk".

Sabi sa WinHEX... "The command "Clone Disk" is part of the Tools menu. This function copies a defined number of sectors from a source to a destination disk. Both disks must have the same sector size. In order to effectively duplicate a drive (i.e. in order to copy all sectors of the drive), enable the appropriate option, so the correct number of sectors is entered automatically. The destination disk must not be smaller than the source disk"

So, to Copy a Bootloader without using USBTerm, kelangan ng full version ng WinHEX, bootloader file, and a SD/MMC reader/writer.

Di ko pa to na-try pero sabi sakin, just choose clone disk and just select the  the bootloader file to the drive assigned to your memory card...

@spv_dman

i still have 0.99 bootloader on my phone... does upgrading to qtek 1.50.91 will unlock my unit?

[dinoalbert]

i think you have to unlock first your SAP before you upgrade to Qtek.

Qtek will not unlock your SAP...instead it will retain the status of your SAP...if it is previously unlocked, it will remain unlocked after you upgrade to Qtek (unlike the Smart 1.5 update) and if it is previously locked, it will remain locked after you upgrade to Qtek  :wink:

[BrAGoL]

thanks for your quick reply! need to downgrade it first to 0.98 bootloader then unlock... then proceed to upgrading to qtek 1.5

[kroblanx]

Can somebody please post a copy of bootloader 0.98 here? The i-Mate ROM update sems to be worth the upgrade. It would be great if somebody will post detailed instructions on how to work around the SAP 1.50 update to enable upgrading to the i-Mate ROM. Iba-iba kasi yung instructions dito sa Modaco at ang gulo.

Is there a way to do this without having to use another SAP? Thanks!!

[dinoalbert]

si mar! he was able to upgrade his Smart 1.5 to the i-Mate rom!

Pwede kaya?  :?: Meron kasi ako dito .whx ng 0.98.

[chibako]

pzee, try it. kaya lang if it works, we still need to have a card reader to transfer the .whx 0.98 to a SD card.  

[dinoalbert]

bootloader na .whx can not be copied by just copy-and-paste sa SD (actually pwede magawa kaya lang di marecognize ng phone yung file)...kelangan talaga ng Winhex at SD card reader.

yah kelangan talaga ng card rdr/wrtr para masabi natin na gumana nga cya. so sa mga may balak mag downgrade sa bootloader 0.98 using this method, gez dapat kumpletuhin nyo muna requirements: software and hardware. sori wala pa kong card reader/writer. any idea kung magkano yung ganun?

[chibako]

i think the card reader costs around 1200 up... pero atleast we can have a copy of bootloader 0.98 in our PCs. no need for extra MMC or SD cards.. tama ba yun?

[gpcarreon (MVP)]

Yung bootloader ata comes in .whx format pag nasa PC, parang .iso image. I think ang gagawin ng WinHEX is to wite in a SD Card yung whx image na nasa PC so that marerecognize ito ng device/phone. As mentioned by dinoalbert, di marecognize pag cut-paste lang gagawin. Kelangan dumaan muna sa WinHEX.

Sequence: whx file in PC -> use CloneDisk feature of WinHEX -> WinHEX will encode the image sa SD -> data encoded sa SD yun ang 'bootloader v0.98' na. Pag nakopya na sa SD, pwede mo ng gamitin sa phone (ei to downgrade). Yun ang pagkaka intindi ko sa kanya. Siguro may iba pang way to write a whx file to SD aside from Clone Disk.

Eto yung sinasabi kong "Clone Disk" feature ng WinHEX.

kelangan parin ng extra SD card.

kse doon mo ilagay yung 0.98bootloader .whx file via Winhex program and card reader...pag nakopya na, tanggalin mo card sa reader, then insert mo na sa phone mo...then reboot mo phone, tapos choose mo downgrade bootloader...tapos ok na naging 0.98 na bootloader mo...pwede kana mag-unlock or upgrade rom

tapos tago mo na yung card for future use

:wink:

chibako, tama si dino. kelangan pa rin talaga ng storage card.

BTW yung 0.98 .whx is equivalent to 6.44 MB (6,759,306 bytes).
